Microbiome
It has long been known that every multicellular organism coexists with large prokaryotic ecosystems — microbiomes — that completely cover its surfaces, external and internal. Recent studies have shown that these associated microbiomes are not mere contamination, but instead have profound effects upon the function and fitness of the multicellular organism. We now know that all MCEs are actually functional composites, holobionts, composed of more prokaryotic cells than eukaryotic cells and expressing more prokaryotic genes than eukaryotic genes. A full understanding of the biology of "individual" eukaryotes will now depend on an understanding of their associated microbiomes.

Rethinking on bile acid-brain axis: decoding neurotoxic and neuroprotective landscape in aging and Alzheimer's disease.
Biogerontology, 27(1):37.
Alzheimer's disease (AD) is a progressive neurodegenerative condition in which aging serves as the predominant risk factor. Emerging research underscores the importance of bile acids (BAs), traditionally recognized for their role in digestion, as key signaling mediators involved in both systemic metabolism and neural communication. Disruption of bile acid (BA) metabolism during aging arises from altered hepatic synthesis, gut microbial imbalance, and defective receptor signaling. These changes have been implicated in several neurodegenerative processes, including Aβ accumulation, tau protein abnormalities, mitochondrial impairment, and disturbances in immune regulation. Aging induces a shift in BA composition toward more cytotoxic species, contributing to blood-brain barrier disruption and enhanced neuronal damage. Multi-omics analyses have identified distinct BA signatures in plasma and cerebrospinal fluid of individuals with mild cognitive impairment and AD. These alterations show strong correlations with brain atrophy and progressive cognitive decline. Experimental and early clinical findings suggest potential neuroprotective effects of hydrophilic BAs such as ursodeoxycholic acid and tauroursodeoxycholic acid, along with therapeutic opportunities through modulation of BA receptors and microbiome-driven BA regulation. In the current era of AD research, the gut-liver-brain BA axis emerges as a novel mechanistic framework linking systemic metabolic aging to neurodegeneration. This review examines the molecular pathways through which BA dysregulation influences aging and AD, emphasizing its therapeutic relevance and supporting the development of biomarker-based and precision medicine approaches for neurodegenerative disorders.

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within- and Between-Individual Blood Parasite Diversity Revealed Through Metabarcoding.
Integrative zoology [Epub ahead of print].
Avian blood parasites of the genera Plasmodium, Haemoproteus, and Leucocytozoon are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. This approach limits the detection of mixed infections and the relative frequencies of co-infecting parasites. In contrast, next-generation sequencing (NGS) can resolve these problems but has been underused for haemosporidian lineage identification in samples from the wild. We used an improved PCR protocol and sequencing with Illumina MiSeq to determine haemosporidian assemblages in wild birds captured at a migration stopover site in Bulgaria, Europe. From 406 samples obtained from 52 bird species, we detected 81 haemosporidian lineages in 131 infected samples from 32 species (32% prevalence). On average, individuals were infected with 2.4 lineages, with 59 birds infected by a single lineage, and 21 birds infected with 5-9 lineages. A subset of samples was Illumina- and Sanger-sequenced in parallel, finding mixed infections in 72 samples and 8× higher detection rate of mixed and co-infections through high-throughput sequencing. Both methods identified the same dominant (co-infecting) lineage (91%). Metabarcoding identified common mixed infections of sister lineage groups ("sisterhoods") known for prevalent lineages and morphospecies, including Plasmodium relictum p_SGS1, Haemoproteus motacillae h_YWT2, and Haemoproteus parabelopolskyi h_SYAT01. Some other lineages appeared consistently more dominant. Our study shows that in some host communities, metabarcoding can reveal a great diversity of mixed infections. This opens new horizons to the study of assemblages of haemosporidian parasites, their interactions within individual hosts, and co-evolution with other members of the blood microbiome and the hosts.

Rhizosphere Metabolites and Microbial Communities Shape Lettuce Responses to Oxytetracycline Stress.
Journal of agricultural and food chemistry [Epub ahead of print].
Oxytetracycline (OTC), a persistent antibiotic frequently detected in agricultural soils, can influence plant growth and rhizosphere ecology. Using lettuce (Lactuca sativa L.) as a model, this study compared the effects of OTC under hydroponic and soil cultivation systems and integrated physiological, metabolomic, and microbiome analyses. Hydroponic exposure consistently inhibited growth, whereas soil culture showed a biphasic, dose-dependent pattern─low OTC doses stimulated growth while high doses suppressed it. In soil systems, OTC exposure reprogrammed rhizosphere metabolites and reshaped microbial networks, enriching taxa associated with OTC degradation and plant growth promotion (Chryseolinea, Nitrospira, Devosia, Haliangium). Structural equation modeling indicated that rhizosphere diversity and metabolite profiles mediate plant biomass responses. These findings reveal that rhizosphere metabolite-microbe networks play a key role in modulating plant hormetic responses to antibiotic stress, providing mechanistic insight into antibiotic-plant-microbe interactions in agroecosystems.

Spatial metabolomics reveals the role of penicillic acid in cheese-rind microbiome disruption by a spoilage fungus.
mSystems [Epub ahead of print].
Microbial interactions in cheese rinds influence community structure, food safety, and product quality. But the chemical mechanisms that mediate microbial interactions in cheeses and other fermented foods are generally not known. Here, we investigate how the spoilage mold Aspergillus westerdijkiae chemically inhibits beneficial cheese-rind bacteria using a combination of omics technologies. In cheese-rind community and co-culture experiments, A. westerdijkiae strongly inhibited most cheese-rind community members. In co-culture with Staphylococcus equorum, A. westerdijkiae strongly affected bacterial gene expression, including upregulation of a putative bceAB gene cluster that is associated with resistance to antimicrobial compounds in other bacteria. Mass spectrometry imaging revealed spatially localized production of secondary metabolites, including penicillic acid and ochratoxin B at the fungal-bacterial interface with Brachybacterium alimentarium. Integration of liquid chromatography-tandem mass spectrometry and genome annotations confirmed the presence of additional bioactive metabolites, such as notoamides and circumdatins. Fungal metabolic responses varied by bacterial partner, suggesting species-specific chemical strategies. Notably, penicillic acid levels increased 2.5-fold during interaction with B. alimentarium, and experiments with purified penicillic acid showed inhibition in a dose-dependent manner against this rind bacterium. These findings show that A. westerdijkiae deploys a context-dependent suite of mycotoxins and other metabolites, disrupting microbial community assembly in cheese rinds.IMPORTANCEThis study identifies the chemical mechanisms underlying the negative impacts of Aspergillus westerdijkiae on cheese-rind development, revealing how specialized metabolites like penicillic acid and ochratoxin B influence rind bacterial communities. By integrating biosynthetic gene cluster analyses with mass spectrometry, we demonstrate how chemical communication shapes microbial interactions, with possible implications for food safety and cheese quality. Understanding these interactions is essential for assessing the risks of fungal-driven spoilage and mycotoxin production in cheese-rind maturation. Beyond cheese, these findings contribute to broader microbiome ecology, emphasizing how secondary metabolites mediate microbial competition in natural and fermented food environments.

Community-associated quinolone-resistant and extended-spectrum beta-lactamase-producing Escherichia coli isolates are similar to clinical infection isolates by sequence type and resistome.
mSystems [Epub ahead of print].
Escherichia coli is a public health threat capable of causing multiple types of infection, carrying a variety of antimicrobial resistance genes (ARGs), and disseminating ARGs to other microbes. Since ARG-carrying E. coli can exist as a commensal gut microbe, intestinal E. coli in community-associated (CA) members presents an under-appreciated reservoir of ARGs. We cultured 75 CA E. coli isolates from stool of 64 patients lacking inpatient healthcare exposures >24 hours in the previous 12 weeks. Remnant stool submitted to the Barnes-Jewish Hospital (BJH) microbiology laboratory for Clostridioides difficile testing was plated to MacConkey agar with ciprofloxacin and extended-spectrum beta-lactamase (ESBL) Chrome Agar to isolate resistant E. coli colonies, which were whole-genome sequenced. Isolates were compared to ESBL E. coli genomes published by Mahmud et al. (B. Mahmud, M. A. Wallace, K. A. Reske, K. Alvarado, et al., mSystems 7:e00519-22, 2022, https://doi.org/10.1128/msystems.00519-22), which were collected from bloodstream and urinary tract infections. We identified ESBL genes and quinolone resistance elements in E. coli isolates from all patients, 32 (50%) of whom had no recent antibiotic exposure. Sequence type (ST) 131 isolates carried more quinolone resistance elements but fewer ESBL genes than other STs. Eleven patients carried two distinct E. coli lineages simultaneously. CA ESBL E. coli displayed a lower diversity of beta-lactamase genes but similar rates of antibiotic resistance genes compared to ESBL E. coli reported by Mahmud et al. (https://doi.org/10.1128/msystems.00519-22). Carriage of resistance elements without recent antimicrobial exposure suggests the presence of circulating, resistant E. coli. Our results show the continually evolving resistance profile of CA E. coli, demonstrating the importance of characterizing antimicrobial resistance in the community.IMPORTANCEAntimicrobial-resistant Escherichia coli presents a substantial threat to public health, limiting treatment options and potentially horizontally transferring its resistance to other members of the gut microbiome. Resistance to quinolones and beta-lactams, specifically, hinders treatment of urinary tract and gastrointestinal infections, both commonly caused by E. coli. Tracking successful lineages, such as ST131, within the healthcare setting can inform clinicians about resistance patterns among their patients, but this work shows that other STs present an even higher antimicrobial resistance burden than ST131. In addition to monitoring multiple lineages of antimicrobial-resistant E. coli, it is necessary to identify and understand community-associated carriage of this organism, as evidenced by the increasing prevalence of community-associated ESBL E. coli carriage and our specific results showing similar resistance burdens within the clinic and community. This work presents insight into antimicrobial-resistant E. coli among those without significant healthcare exposures, providing important community-focused surveillance that is currently lacking.

Out of the box: toward new frameworks for understanding human microbiomes.
mSphere [Epub ahead of print].
The study of the human microbiome (mirroring broader practice across biomedical science), has historically defaulted to the use of simplified, socially constructed "boxes," such as racial and ethnic labels, that fail to accurately capture human variation and fundamentally misdirect the search for mechanisms to explain differences in health outcomes. Five years ago, I proposed a "frameshift," a fundamental conceptual shift away from relying on these categories and toward a more nuanced, careful approach to the complexity of human variation. Moving "out of the box" means tackling the difficult but essential work of analyzing microbial variation through a systems lens, connecting large-scale ecosocial drivers to individual mechanisms and outcomes. In this Full Circle review, I discuss rapid progress in the field toward this new framework and argue that by adopting transdisciplinary methods, we can generate more accurate, actionable, and equitable solutions for human health.

Recurrent left-sided diverticulitis after surgery: A systematic review and single arm meta-analysis.
Colorectal disease : the official journal of the Association of Coloproctology of Great Britain and Ireland, 28(1):e70368.
INTRODUCTION: Recurrent diverticulitis after resection remains a key concern despite advances in minimally invasive surgery. These recurrences may result from incomplete resection of the diseased segment, unrecognized synchronous diverticulosis or ongoing alterations in colonic motility and microbiome composition. This systematic review and single-arm meta-analysis aimed to estimate long-term recurrence and stoma rates following elective surgery for left-sided diverticulitis.
METHODS: Following PRISMA guidelines and PROSPERO registration, PubMed, Cochrane and Scopus databases were searched (2000-2025) for studies reporting recurrence after elective resection. Single-arm meta-analysis of proportions was performed using random-effects models. Quality was assessed using the JBI Checklist, while subgroup and sensitivity analyses explored heterogeneity. A comparative meta-analysis with medical treatment was not performed due to selection bias, crossover and lack of standardized non-operative protocols.
RESULTS: Twenty-four studies (7,525 patients; mean follow-up 53 months) were included. Pooled recurrence rate was 6.2% (95% CI: 4.8-8.0%; I[2] = 80.6%), with no difference between RCTs (6.3%) and observational studies (6.1%) or complicated vs. uncomplicated disease. Stoma rate (16 studies, 6,400 patients) was 17.1% (95% CI: 8.4-31.9%; I[2] = 99.3%), significantly higher in complicated (31.0%) than uncomplicated (5.5%) cases (p = 0.009) and significantly lower post-2020 (8.0% vs. 31.2%; p = 0.003). Quality was high in 92% of studies, while sensitivity analyses confirmed robustness.
CONCLUSIONS: Surgical resection achieves durable control with low recurrence and stoma rates. Research priorities include standardized definitions of recurrence, assessing long-term QOL and exploring microbiome influences to refine patient selection and minimize residual risk.

Stoma rate (16 studies, 6,400 patients) was 17.1% (95% CI: 8.4-31.9%; I[2] = 99.3%), significantly higher in complicated (31.0%) than uncomplicated (5.5%) cases (p = 0.009) and significantly lower post-2020 (8.0% vs. 31.2%; p = 0.003). Quality was high in 92% of studies, while sensitivity analyses confirmed robustness.
CONCLUSIONS: Surgical resection achieves durable control with low recurrence and stoma rates. Research priorities include standardized definitions of recurrence, assessing long-term QOL and exploring microbiome influences to refine patient selection and minimize residual risk.},

Defining the Intestinal eCBome and Oxylipin Signaling Systems in a TDP-43 Mouse Model of Frontotemporal Dementia.
FASEB journal : official publication of the Federation of American Societies for Experimental Biology, 40(2):e71306.
Frontotemporal dementia (FTD) is a group of early onset and progressive disorders, characterized by degeneration in the frontal and temporal lobes, and subsequent deterioration in cognition, personality, social behavior, and language, with aggregates of the RNA-binding protein TDP-43 being present in ~45% of the cases. We reported alterations of the endocannabinoidome (eCBome) in the brain of a TDP-43 mouse model of FTD. Here we investigated the small intestinal eCBome, oxylipins, and, preliminarily, the gut microbiome. The duodenum, jejunum, and ileum of TDP-43 overexpressing versus wildtype mice were investigated. Lipid mediators were measured by HPLC-MS/MS, and mRNA expression of genes involved in eCBome mediator action and metabolism, or intestinal permeability and inflammation, was analyzed by qPCR. Intestinal content microbiota composition and fecal short-chain fatty acids were studied by 16S DNA sequencing and GC-FID, respectively. Alterations were observed in TDP-43 mice for polyunsaturated fatty acids, N-acyl-ethanolamines, and oxylipins in the duodenum and the jejunum, and for oxylipins and 2-monoacylglycerols in the ileum. Regarding the receptors, mRNA expression of Cnr1 and Gpr119 was increased in the ileum, and that of Pparg in the duodenum, where Gpr55 was instead down-regulated. Regarding the enzymes, Faah and Napepld expression was increased in the ileum. Preliminary gut microbiota data suggest increases of Paraprevotella and Monoglobus in the feces, of DNF00809 in the ileum, and of Butyricicoccus, Candidatus_Arthromitus, and Oscillospira in the cecum, where Paraprevotella, Mucispirillum, and Akkermansia were instead decreased. Fecal acetic, butyric, and isobutyric acid were reduced. We suggest the existence of lipid signal-mediated gut-brain interactions in FTD.

A review of skin microbiome and new challenges to cosmetic microbiome-friendly formulations.
International journal of cosmetic science [Epub ahead of print].
Human skin is a complex ecosystem that hosts diverse species of microorganisms. Unbalanced conditions caused by intrinsic and/or extrinsic factors can lead to dysbiosis, presenting symptoms, such as dryness, high transepidermal water loss, reduced barrier protection, premature ageing, and in severe cases, inflammatory dermatoses. Strategies to maintain the skin microbiome balance are becoming increasingly suggested, with prebiotic, probiotic, or postbiotic ingredients promoting the diversity and relative abundance of important microorganisms. Topical products directly influence this balance, both traditional ingredients and specific active ingredients. The concentration and combination of these ingredients, as well as the pH of the final product, are extrinsic characteristics that can affect homeostatic skin condition. Focused on repairing or preserving the skin microbiota, microbiome-friendly cosmetics are gaining prominence in the cosmetics industry, with a focus on reducing or replacing ingredients with adverse effects on skin microbiota or adding positive compounds for the microbiota. This review approaches the main characteristics of the skin microbiome, in symbiosis and dysbiosis, elucidates strategies for skin microbiota rebalance, and addresses the challenges of developing microbiome-friendly products through studies of the interaction between skin microbiome and substantial classes of cosmetic ingredients, such as surfactants, lipophilic compounds, preservatives, fragrances, vitamins, and UV filters. The presented findings elucidate the relationship between the host, the skin microbiome, and the use of cosmetics, which could serve as a tool for the development of microbiome-friendly cosmetics. Given the growing popularity of this topic, we also highlight the need for further research focused on the dynamics between the skin microbiome and cosmetic ingredients.

The Microbiome Modulates Corneal Wound Healing via the Induction of Cholesterol Sulfotransferase Pathway.
FASEB journal : official publication of the Federation of American Societies for Experimental Biology, 40(2):e71429.
The ocular surface is in direct contact with the external environment and is susceptible to injury from dust, dryness, or other foreign objects. Once corneal injury occurs, a local inflammatory response is triggered, followed by effective repair of the epithelial layer. In this study, we demonstrated that antibiotic treatment delayed corneal wound healing in mice. LC-MS/MS-based untargeted lipidomics and qPCR analyses revealed that the levels of cholesterol sulfate (CS) and the CS-synthesizing enzyme SULT2B1 were significantly upregulated by antibiotic treatment, and SULT2B1 knockout mice exhibited accelerated corneal wound healing along with increased recruitment of neutrophils and eosinophils. Topical application of CS delayed corneal wound healing. In vitro scratch assays revealed that CS delayed the wound healing of human corneal epithelial cells, potentially by inhibiting the DOCK2-Rac pathway. These results highlight the role of commensal bacteria in controlling corneal wound healing via the cholesterol-sulfotransferase pathway.

Vitamin B12 and Affective Disorders: A Focus on the Gut-Brain Axis.
Alpha psychiatry, 26(6):49138.
Accumulating evidence highlights the role of Vitamin B12 (VitB12) in the pathophysiology of affective disorders. However, its influence on brain function and the underlying mechanisms remain incompletely understood. In humans, VitB12 is obtained solely from dietary sources, primarily animal-based foods. VitB12 deficiency leads to the accumulation of homocysteine, a known contributor to emotional and behavioral dysregulation. VitB12 plays a critical role in maintaining neuron stability, synapsis plasticity, and regulating neuroinflammation by modulating key bioactive factors. These processes help to alleviate hippocampal damage, mitigate blood-brain barrier disruption, reduce oxidative stress, and enhance both structural and functional connectivity-collectively contributing to resilience against affective disorders. VitB12 from both diet and microbial sources is essential to gut homeostasis. Within the gut lumen, it stabilizes gut microbial communities, promotes short-chain fatty acid (SCFA) production, and supports neurotransmitter metabolism (e.g., serotonin and dopamine) via its role in S-adenosyl-l-methionine biosynthesis. Crucially, VitB12, gut microbiota, SCFAs, intestinal mucosa, and vagal nerve signaling interact synergistically within the gut-brain axis (GBA) to maintain gut microenvironment stability, protect the gut-blood barrier, and suppress neuroinflammatory cascades, eventually reducing the susceptibility to affective disorders. This review synthesizes current evidence on the involvement of VitB12 in the GBA, its association with mood regulation, and its potential as a nutritional adjunct in managing affective disorders. By elucidating this integrative mechanism, we provide new insights into targeting the GBA to improve clinical outcomes in affective disorders.

Effects of chronic allergic lung inflammation on gut microbiota and depression-like behavior in mice.
Exploration of asthma & allergy, 3:.
AIM: Emerging epidemiological studies have reported a link between allergic diseases, including asthma, and depression. Evidently, the gut microbiota is involved in the pathogenesis of asthma and depression. Therefore, we investigated whether allergic lung inflammation in mice causes gut microbial dysbiosis, via the gut-brain axis, which is potentially associated with depression.
METHODS: Wild-type C57BL/6J female mice were sensitized with intranasal house dust mite (HDM) antigen or phosphate-buffered saline (PBS) for 6 weeks to induce chronic allergic lung inflammation. Sucrose preference tests were performed for assessing depression. Fecal samples were collected, and 16S ribosomal RNA gene sequencing was performed to detect differences in gut microbiota composition between the HDM and PBS groups. The distance calculation, clustering of operational taxonomic units, rarefaction analysis, and estimator calculation (α- and β-diversity) were performed.
RESULTS: There was a significant difference in β-diversity (Bray-Curtis dissimilarity, F-statistics = 6.16, p = 0.001) of the gut microbiota between HDM and PBS groups. However, there was no difference in the α-diversity. We observed multiple differentially abundant bacteria in the HDM and PBS groups. The order class Clostridia (p = 0.0036) and genus Faecalibaculum (p = 0.028) were more abundant in the HDM group, whereas the phylum Firmicutes (p = 0.037) and genera Dubosiella (p = 0.00024) and Turicibacter (p = 0.037) were more abundant in the PBS group. Notably, the relative abundance of some bacteria was correlated with the sucrose preference test results.
CONCLUSIONS: Six weeks of intranasal HDM administration to mimic the chronic status of lung inflammation in asthma changed the gut microbiome in mice and was associated with depression-like behavioral changes.

Potential role of nanopharmacology in reducing neuroinflammation associated with hypertension and metabolic disorders.
World journal of experimental medicine, 15(3):106743.
Hypertension disrupts cerebral blood flow, leading to endothelial dysfunction, breakdown of the blood-brain barrier (BBB), and inflammatory cell infiltration. This cascade triggers glial cell activation, increases oxidative stress, and causes pro-inflammatory cytokine release, creating a neurotoxic environment. In this context, we explore the intricate connection between hypertension, neuroinflammation, and neurodegeneration, as well as how hypertension interacts with other metabolic disorders, such as obesity and diabetes, to further worsen neuroinflammation. Additionally, we discuss the role of the renin-angiotensin-aldosterone system, the impact of the microbiome, and the potential contribution of chronic infections in exacerbating neuroinflammation. It is essential to emphasize the potential of nanotechnology to transform therapeutic approaches. Nanoparticle-based drug delivery systems can enhance the bioavailability and selectivity of antihypertensive drugs, antioxidants, and neuroprotective compounds, enabling targeted delivery across the BBB. By combining effective blood pressure management with nanotechnology-enabled therapies that modulate inflammation, oxidative stress, and protein aggregation, we can explore new avenues for preventing and treating hypertension and metabolic disorder-associated neurodegenerative conditions. Ultimately, hypertension significantly contributes to neuroinflammation and neurodegeneration by promoting neuronal cell death, primarily through impaired cerebral blood flow and disruption of the BBB. The interaction of hypertension with metabolic disorders exacerbates these effects. However, advancements in our understanding and new technologies reveal promising nanopharmacological approaches for targeted drug delivery to the brain, thereby improving treatment outcomes, enhancing adherence, and reducing side effects.

Understanding the intricate interactions between microbiota and host.
World journal of experimental medicine, 15(3):101277.
The review examines the intricate relationship between the microbiota and its host, highlighting how these microbial communities influence various physiological functions beyond simple coexistence. The microbiota plays a crucial role in regulating the immune system, metabolism, and overall health. We explore the diverse microbial populations inhabiting different body regions and their essential contributions to maintaining balance within the host. Recent research has uncovered molecular mechanisms that govern microbiota-host interactions, offering new insights into how these microbes support health and, conversely, how imbalances known as dysbiosis can increase susceptibility to diseases. While much attention has been given to the gut microbiota, this review also explores the influence of microbes in other parts of the body, including their effects on various organs and tissues. Additionally, we discuss emerging evidence on the gut-brain axis, illustrating how the microbiota can impact brain function and behavior. Understanding this connection could open new possibilities for treating neurological and psychological disorders. Finally, we evaluate microbiota-based therapies such as probiotics and fecal microbiota transplantation, emphasizing the importance of personalized approaches. By integrating findings from multiple disciplines, this review provides a comprehensive perspective on the microbiota's vital role in human health and its potential as a therapeutic target.

The gut-bone axis: potential influence of anthocyanins and implications for postmenopausal osteoporosis.
Food science and biotechnology, 35(1):13-25.
With the aging population worldwide and increased life expectancy, the risk of postmenopausal osteoporosis (PMO) is an increased public health concern. Current treatments for PMO have declined in use over the past decade which has led to an increased focus on finding dietary agents that possess antioxidant and anti-inflammatory properties for prophylaxis and treatment of osteoporosis. Anthocyanins (ACNs) have been shown to exert therapeutic effects in chronic diseases due to their antioxidant and anti-inflammatory properties. ACNs are also thought to be involved in modulating the gut microbiome owing to their prebiotic properties. The gut microbiome has been implicated as a potential target for osteoporosis prevention and treatment since it can modulate immune and endocrine systems, which influence bone metabolism. This review summarizes findings related to ACNs' influence on the gut-bone axis, with a focus on the immune and endocrine systems and potential implications for PMO prevention.

The gut microbiome has been implicated as a potential target for osteoporosis prevention and treatment since it can modulate immune and endocrine systems, which influence bone metabolism. This review summarizes findings related to ACNs' influence on the gut-bone axis, with a focus on the immune and endocrine systems and potential implications for PMO prevention.},

Comparative Profile of Microbiome in Normal Skin and Acne Vulgaris Skin Patients.
Clinical, cosmetic and investigational dermatology, 19:1-7.
INTRODUCTION: Changes in the skin microbiome are associated with acne vulgaris (AV), a condition characterized by comedones, papules, and pustules. While some bacteria have been studied, many others remain unexplored, highlighting the need to understand the microbiome differences between acne-prone and normal skin. This study aimed to compare skin microbiome profiles between AV patients and healthy individuals and to explore associations with microbial diversity and specific bacterial populations involved in AV pathogenesis.
METHODS: A total of 144 participants were recruited, comprising 36 AV patients and 108 healthy controls. Skin samples were collected from the left cheek after standardized preconditioning. DNA was extracted using the DNeasy PowerSoil Kit™, and the V3-V4 region of 16S rRNA was amplified and sequenced. Microbial diversity was assessed by the Shannon index, and correlations with sebum levels were analyzed.
RESULTS: The results revealed significant differences in microbial diversity, with AV patients exhibiting a markedly lower Shannon index compared to controls, indicating decreased microbial diversity and potential dysbiosis. While the relative abundance of Cutibacterium acnes, a bacterium commonly associated with AV, showed no significant differences between the two groups, the prevalence of Staphylococcus epidermidis was notably higher in AV patients. This suggests that S. epidermidis may play a complex role in the inflammatory processes associated with AV. Moreover, the study identified a negative correlation between microbial diversity and sebum levels, suggesting that increased sebum production may favor the growth of S. epidermidis, potentially exacerbating the condition.
CONCLUSION: These findings highlight the interaction between host factors and microbial composition. This study emphasizes the role of skin microbiome dysbiosis in acne vulgaris and provides insights for future microbiome-based therapeutic strategies. Further research is needed to clarify microbial mechanisms and potential interventions targeting the microbiome in the management of acne vulgaris.

Clinical Safety and Tolerability of Bifidobacterium bifidum BBi32: An 8-Week Randomized, Double-Blind, Placebo-Controlled Trial With Genomic and In Vitro Corroboration.
Food science & nutrition, 14(1):e71420.
Bifidobacterium bifidum BBi32, isolated from a healthy infant, underwent a multi-tiered safety assessment to evaluate its genetic features, in vitro properties, and effects on gut microbiota and host biomarkers. Whole-genome sequencing (WGS) and functional annotation were performed alongside in vitro assays assessing acid and bile tolerance, mucin degradation, hemolysis, Caco-2 cytotoxicity, and antibiotic susceptibility. Acute oral toxicity was tested in mice. A randomized, double-blind, placebo-controlled clinical trial (n = 40, 8 weeks) evaluated tolerability and exploratory endpoints, including hematology, liver and renal function, LL-37 levels, gastrointestinal symptom scores, and 16S rRNA-based microbiome profiling. The BBi32 genome comprised a 2.2 Mbp circular chromosome with 99.99% average nucleotide identity to the type strain, no plasmids, and no acquired antimicrobial resistance or virulence genes. Functional categories were enriched for ABC transporters, purine metabolism, and defense mechanisms. BBi32 demonstrated tolerance to acid and bile, lacked mucin-degrading, or hemolytic activity, showed no cytotoxicity to Caco-2 cells, and was susceptible to most antibiotics. Acute toxicity test yielded an LD50 > 2 × 10[10] CFU/kg with no adverse effects. In the clinical trial, daily BBi32 administration (3 × 10[10] CFU) was well tolerated, with no hematological or hepatic abnormalities. Compared with placebo, BBi32 reduced uric acid, urea, and creatinine levels, increased LL-37, and improved gastrointestinal symptom scores. Microbiome analysis revealed higher alpha diversity, distinct community clustering, enrichment of Romboutsia, and predicted functional shifts toward amino acid biosynthesis and peptidase activity. Genomic, in vitro, toxicological, and clinical data collectively indicate that BBi32 meets key safety criteria and favorably modulates host and microbiome biomarkers, supporting its probiotic potential.

Therapeutic Potential of Irpex lacteus Polysaccharides in Lupus Nephritis: Insights From Gut Microbiota and Metabolomics Analysis in MRL/Lpr Mice.
Food science & nutrition, 14(1):e71446.
Polysaccharides from Irpex lacteus (PCP) were evaluated for their therapeutic effects on lupus nephritis (LN) in MRL/lpr mice. After 8-week interventions with low- and high-dose PCP, we systematically evaluated the therapeutic efficacy by measuring the levels of autoantibodies, the expression of inflammatory cytokines, and renal function-related parameters. Finally, 16S rDNA gut microbiome sequencing with metabolomics analysis was used to explore the pharmacological mechanism of PCP intervention in LN. PCP could reverse the phenotype of MRL/lpr mice, reduce autoantibody levels, alleviate inflammatory responses, and improve renal function. Gut microbiome analysis found that PCP can improve gut microbiota composition and abundance of two phyla (Firmicutes, Bacteroidota) and five genera (Lachnospiraceae NK4A136 group, Alistipes, Butyricicoccus, Bacteroides, Lactobacillus), which play an important role in the process of PCP intervention on metabolism in MRL/lpr mice. UHPLC-MS untargeted metabolomics showed that PCP significantly affects multiple key differential metabolites, including Linoleic acid, L-Phenylalanine, L-Tyrosine, and 56 other metabolites. These metabolites are primarily involved in metabolic pathways such as tryptophan metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, tyrosine metabolism, linoleic acid metabolism, and arachidonic acid metabolism. Correlation analysis between gut microbiota and differential metabolites reveals a close relationship, suggesting that gut microbiota promoting host metabolism may be one of the mechanisms by which PCP treats LN. PCP alleviates LN by modulating the "microbiota-metabolism axis," reducing autoantibodies, inflammation, and renal damage, while reshaping gut microbiota and regulating key metabolic pathways.

Pathogen spectrum and management strategies for opportunistic infections in lung cancer in the immunotherapy era: recent advances from fungi to mycobacteria.
American journal of cancer research, 15(12):5140-5167.
Lung cancer is one of the most common cancers and the leading cause of cancer death worldwide. Opportunistic infections (OI) are increasingly recognized in this population due to disease-related immune dysfunction and treatment-induced immunosuppression. Compared with the chemotherapy era, the use of immune checkpoint inhibitors and targeted agents has shifted the OI profile. Pneumocystis jirovecii pneumonia (PJP) and invasive pulmonary aspergillosis (IPA) are reported more often in older adults and patients with lymphopenia, while tuberculosis (TB) and nontuberculous mycobacteria (NTM) cluster in those with structural lung disease (e.g., bronchiectasis, cavities) and prolonged immunosuppression. High-risk features include absolute lymphocyte count <500/µL, corticosteroids ≥20 mg prednisone-equivalent for ≥4 weeks, airway obstruction, prior TB, chronic obstructive pulmonary disease/interstitial lung disease (ILD), and recent broad-spectrum antibiotics. Diagnosis should integrate high-resolution computed tomography (HRCT) patterns (e.g., diffuse ground-glass for PJP; nodules with halo sign for IPA), microbiology [bronchoalveolar lavage fluid (BALF) culture/microscopy, galactomannan (GM)/β-D-glucan (BDG)], and metagenomic next-generation sequencing, interpreted against host factors and treatment timeline, while carefully distinguishing immune-related pneumonitis and TKI-associated ILD. Prophylaxis with TMP-SMX is recommended for high-risk patients; voriconazole (or isavuconazole) is first-line for IPA with attention to drug-drug interactions; TB/NTM regimens require coordination with anticancer therapy, especially where rifamycins interact with TKIs. Vaccination (influenza, pneumococcus, zoster) and antimicrobial stewardship are essential. Future work should validate risk scores prospectively and clarify microbiome-immunotherapy-infection relationships.

Decoding the metastatic nexus: how chronic stress reprograms neuroendocrine-metabolic-microbiome circuits to fuel tumor metastasis.
American journal of cancer research, 15(12):5058-5083.
Metastasis, the leading cause of death in patients with solid tumors, involves the spread of cancer cells to distant organs. While genetic and environmental factors contribute, chronic stress is a crucial factor in metastatic progression by disrupting neuroendocrine, immune, metabolic, and microbial homeostasis. This review synthesizes evidence linking chronic stress to tumor metastasis through three pathways: (1) direct effects on tumor cell metabolism, (2) remodeling of the tumor microenvironment, and (3) dysregulation of the gut microbiota. Describe how activation of the hypothalamic-pituitary-adrenal axis and sympathetic nervous system influence epithelial-mesenchymal transition, immune evasion, and angiogenesis via β-adrenergic and glucocorticoid receptor signaling. Explore how microbial metabolites and barrier dysfunction influence immune and neuroendocrine circuits, creating a pro-metastatic loop. Finally, we highlight therapeutic strategies, including psychological interventions and pharmacologic approaches, to alleviate chronic stress. This review proposes a mechanistic framework linking neuroendocrine signaling, metabolic reprogramming, and the microbiome-immune axis.

Targeted therapies for meibomian gland dysfunction - The role of antibiotics in meibomian gland dysfunction management.
Taiwan journal of ophthalmology, 15(4):516-525.
Meibomian gland dysfunction (MGD) is a leading cause of evaporative dry eye, significantly impairing the quality of life. Bacterial proliferation and inflammation play central roles in the pathogenesis of MGD, creating a vicious cycle of gland obstruction and ocular surface instability. Antibiotics, particularly tetracyclines (e.g. doxycycline and minocycline), and macrolides (e.g. azithromycin and erythromycin), are widely used as adjunctive therapy for moderate-to-severe or refractory MGD. This review conducted a comprehensive literature search of PubMed, focusing on original peer-reviewed articles published in English that reported on the efficacy and/or safety of oral or topical antibiotics for MGD or blepharitis. Eligible studies were identified using the specific search terms, screened by title and abstract, and selected based on predefined inclusion and exclusion criteria. Relevant data were extracted and synthesized, with an emphasis on randomized controlled trials and comparative studies. The review indicates that both oral and topical antibiotics improve subjective symptoms, tear film stability, ocular surface staining, meibum quality, and lid margin abnormalities in the short term. Oral azithromycin may be at least as effective as doxycycline, with a shorter treatment course and fewer adverse events, while topical azithromycin offers similar or superior efficacy to systemic regimens with reduced systemic exposure. However, benefits are usually limited to active treatment periods, and optimal dosing and duration remain uncertain. Long-term efficacy, safety, risk of resistance, and effects on the ocular microbiome require further investigation. Antibiotics should be used judiciously as part of a comprehensive, individualized management strategy for MGD.

An In vitro Study of the Isolation of Candidal Strains in Patients at Increased Risk of Oral Squamous Cell Carcinoma.
Journal of pharmacy & bioallied sciences, 17(Suppl 4):S2870-S2872.
BACKGROUND: OSCC stands as a prominent oral malignancy that develops because of lifestyle behavior and microbial activity. The pathogenesis of OSCC receives attention through modern research since Candida species reportedly contribute to the development of OSCC through inflammatory responses and nitrosamine generation and epithelial tissue malformation.
MATERIALS AND METHODS: Sixty subjects participated in this in vitro study, which was separated into two distinct groups: Group A with 30 patients who had high OSCC risk oral lesions (leukoplakia and erythroplakia) and Group B which included 30 healthy subjects. A laboratory research involved collecting samples through swabs from saliva and mucosa, which were subsequently cultured on Sabouraud Dextrose Agar (SDA) alongside CHROMagar for fungal detection. The researchers identified isolated colonies by checking their ability to form germ tubes combined with carbohydrate assimilation tests.
RESULTS: Out of the 30 Group A samples, 80% (24/30) demonstrated candidal growth where Candida albicans constituted 70.8% of strains and Candida tropicalis made up 16.7% alongside Candida glabrata counting for 12.5%. The overall candidal growth among participants in Group B was limited to 30% (9/30) as C. albicans constituted 88.9%, whereas C. glabrata accounted for 11.1%. The incidence of candidal colonization proved markedly higher among the high-risk group compared to controls according to statistical analysis (P = 0.002).
CONCLUSION: The numbers of Candida species, particularly C. albicans, rise substantially within the oral environments of patients dealing with potentially malignant disorders. The obtained data support the possibility that oral cancer development may be related to candidal colonization, thus demanding additional studies on this association.

Determination of Gut Microbiome Patterns Associated with Developing Active Tuberculosis in a Case-Control Study.
Journal of pharmacy & bioallied sciences, 17(Suppl 4):S3069-S3071.
BACKGROUND: The gut microbiome plays a critical role in modulating systemic immunity and may influence susceptibility to infectious diseases, such as tuberculosis (TB). This study aimed to compare gut microbial profiles between individuals with active pulmonary TB and healthy controls to identify potential microbial signatures associated with disease development.
METHODS: A hospital-based case-control study was conducted with 90 participants: 45 treatment-naïve TB patients and 45 healthy controls. Stool samples were collected and analyzed using 16S rRNA sequencing. Microbial diversity was assessed using the Shannon index, and relative abundances of key bacterial phyla were compared. Statistical analysis included Mann-Whitney U tests and LEfSe for differential taxa identification.
RESULTS: TB patients showed significantly lower alpha diversity (Shannon index: 2.91 ± 0.37) compared to controls (3.81 ± 0.28, P < 0.001). The relative abundance of Proteobacteria was significantly higher in TB cases, while Firmicutes and Bacteroidetes were more abundant in controls. These findings indicate a pro-inflammatory gut microbiota shift in active TB.
CONCLUSION: Active tuberculosis is associated with gut microbial dysbiosis, marked by reduced diversity and altered bacterial composition. These microbial signatures could aid in early diagnosis and serve as future targets for microbiome-based interventions.

A prognostic nomogram for colorectal cancer: integrating blood microbiome and clinical factors.
Journal of gastrointestinal oncology, 16(6):2651-2663.
BACKGROUND: The microbiota is pivotal in colorectal cancer (CRC), yet the prognostic value of the blood microbiome and its utility in clinical prediction models remain poorly explored. This study aims to develop a blood microbiome-associated prognostic score (MAPS) that integrates blood microbiome data with clinical factors to improve the accuracy of CRC prognosis prediction and enhance our understanding of the tumor microenvironment (TME).
METHODS: We analyzed whole-genome and transcriptomic sequencing data of CRC patients from The Cancer Genome Atlas (TCGA). A MAPS was developed from blood microbiome data using the least absolute shrinkage and selection operator (LASSO) Cox regression algorithm. A nomogram integrating MAPS and key clinical factors was constructed to predict overall survival (OS). Its predictive accuracy was validated via time-dependent receiver operating characteristic (ROC) analysis, yielding area under the curve (AUC) values for 1-, 3-, and 5-year OS. Underlying mechanisms were investigated through gene set enrichment analysis (GSEA) and immune cell infiltration estimation from matched RNA sequencing (RNA-seq) data.
RESULTS: The MAPS, comprising seven key blood microbes, was an independent prognostic factor. The integrative nomogram demonstrated robust predictive performance, with AUCs of 0.800, 0.805, and 0.755 for predicting 1-, 3-, and 5-year OS, respectively. Mechanistically, the high-MAPS subgroup exhibited enriched pro-tumorigenic pathways (e.g., inflammatory response, hypoxia) and an immunosuppressive TME characterized by increased Treg cell infiltration. We further identified S100A8 and PROK2 as potential therapeutic targets.
CONCLUSIONS: Our study delivers a validated prognostic nomogram based on the blood microbiome and elucidates its link to an immunosuppressive TME, highlighting its dual utility in patient stratification and target discovery.

Microbial allies: shaping growth, physiology, and rhizosphere dynamics of onion (Allium cepa L.).
PeerJ, 14:e20566.
The present study investigates the dual impact of microbial biofertilizers on the phenotypic performance and rhizosphere microbiome composition in an onion crop. A pot experiment was conducted with seven treatments of microbial inoculants, such as Azotobacter, Azospirillum, Piriformospora indica, phosphate solubilizing bacteria (PSB), and control treatments with and without chemical fertilizers. The growth, physiological, and biochemical traits of onion were assessed alongside rhizospheric soil microbiome profiling using 16S rRNA metagenomic sequencing. Significant enhancement in plant height, leaf number, leaf area, chlorophyll content, photosynthetic rate, and antioxidant enzyme activity with low leaf temperature was observed in plants inoculated with Azotobacter and Azospirillum. Notably, the Azotobacter treatment yielded a significant enhancement in the bulb phenol content. Rhizosphere metagenomic analysis revealed 17 dominant phyla, with Actinobacteria (25.3%), Proteobacteria (22.2%), Firmicutes (12.8%), and Chloroflexi (11.02%) comprising over 70% of the total microbiome. Alpha and beta diversity metrics indicated that microbial inoculation, especially with Azospirillum and PSB, enriched the soil microbial community structure. Distinct clustering and correlations with specific microbial taxa such as Candidatus Nitrososphaera and Pseudomonas were observed in response to individual biofertilizer treatments. This study highlights the potential of biofertilizers not only in enhancing onion growth and development but also in modulating beneficial rhizosphere microbial communities. Integrating biofertilizers into onion production systems could reduce the dependency on chemical fertilizers and promote sustainable crop management.

Cross-sectional comparative shotgun metagenomic analysis of the subgingival resistome in healthy subjects and patients with periodontitis from four countries.
Journal of oral microbiology, 18(1):2610588.
BACKGROUND: The oral cavity is a known reservoir of antibiotic resistance genes (ARGs), but little is known about their subgingival distribution across health states and regions.
OBJECTIVE: This study aimed to characterize and compare the subgingival resistome and mobile genetic elements (MGEs) in healthy subjects (HS) and periodontitis patients (PP) from Belgium, Chile, Peru and Spain.
DESIGN: Subgingival samples pooled from the deepest site of each quadrant of 40 HS and 40 PP were analyzed via shotgun metagenomic sequencing. After human DNA depletion, the microbial composition was assessed with MetaPhlAn 4.0; ARGs were identified using MEGAHIT and AMRFinderPlus; and MGEs with MGEfinder.
RESULTS: ARG richness was significantly higher in PP (mean 3.98) than in HS (2.15). PP from Peru showed more ARGs than HS from Chile and Spain. In total, 28 ARGs were found, conferring resistance to eight antibiotic classes. β-lactam, tetracycline and aminoglycoside resistance were more abundant in PP. Macrolide resistance was lower in Chilean samples than in Peruvian and Spanish ones. Additionally, 99 MGE-associated genes were detected, with 16 differing by diagnosis and 78 by country.
CONCLUSIONS: Subgingival resistome profiles vary significantly by periodontal status and geography, underscoring the influence of clinical and regional factors on antimicrobial resistance in the oral microbiome.

The Gut Microbiota-Insulin Resistance Axis: Mechanisms, Clinical Implications, and Therapeutic Potential.
FASEB bioAdvances, 8(1):e70080.
Emerging evidence highlights the pivotal role of the gut microbiota (GM) in regulating host metabolism and contributing to the development of insulin resistance (IR). Gut dysbiosis alters the production of critical metabolites, including short-chain fatty acids (SCFAs), bile acids, indole derivatives, and trimethylamine N-oxide (TMAO), which influence intestinal barrier integrity, inflammatory pathways, and glucose homeostasis. Recent clinical and translational studies indicate that SCFAs can improve fasting insulin and HOMA-IR, although the magnitude of benefit varies substantially across individuals, highlighting ongoing controversy surrounding their metabolic effects. Altered microbial regulation of bile-acid metabolism has also been implicated in impaired lipid and glucose signaling, reinforcing the relevance of FXR- and TGR5-mediated pathways in IR. Elevated TMAO levels have further been associated with adverse metabolic outcomes, though debate persists regarding its causal role versus its function as a diet-dependent biomarker. Microbiota-targeted strategies, including dietary fiber, probiotics, and fecal microbiota transplantation (FMT), show potential to modulate these metabolic pathways, yet clinical results remain inconsistent. This narrative review synthesizes recent mechanistic discoveries and clinical findings on microbiota-derived metabolites in IR, highlights key controversies, and outlines future priorities for translating microbiome science into effective and personalized interventions for metabolic disease prevention and management.

Gut microbiome in biliary atresia.
World journal of pediatric surgery, 9(1):e001068.
Biliary atresia (BA) is a progressive cholangiopathy of infancy and the leading cause of pediatric liver transplantation. Despite surgical intervention with the Kasai portoenterostomy, long-term outcomes remain poor, with many patients progressing to cirrhosis. Emerging evidence implicates the gut microbiota-a dynamic ecosystem crucial to immune development and liver homeostasis-in BA pathogenesis and clinical progression. This review synthesizes current literature on gut microbiota composition in BA before and after the Kasai procedure, highlighting consistent patterns of dysbiosis, including pathobiont expansion and depletion of beneficial microbes such as Bifidobacterium. The review explores associations between microbial profiles and clinical outcomes-highlighting potential mechanisms involving bile acid metabolism, microbial translocation, and immune modulation. Further understanding of gut-liver-microbiota interactions in BA may inform microbiome-targeted therapies to improve native liver survival.

Healthy human gut microbiome: Towards standardized research.
AIMS microbiology, 11(4):786-820.
OBJECTIVE: An increasing number of international researchers are focusing on the taxonomic composition of fecal microbiota and its correlation with disorders. Thousands of researchers compare conditionally healthy cohorts to those with specific diseases to identify potential markers. However, clinical application requires assessing the feasibility of synthesizing these findings and establishing reference intervals for normal gut flora, at least at higher taxonomic levels.
DESIGN: This study involves a systematic review and meta-analysis of human gut microbiota research based on 16S rRNA gene next-generation sequencing (NGS). Relevant research was sourced following the PRISMA guidelines. Descriptive statistics, linear regression analysis by weighted least squares method, Mann-Whitney test, and Benjamini-Hochberg procedure adjustments were employed. The study has been registered with PROSPERO (CRD42023431467).
RESULTS: Of the 4,346 studies initially identified, 86 publications involving 20,748 unique participants met the quality criteria and were included in the analysis of the impact of fecal sample preparation on taxonomic composition. The phylotype composition, in relation to preprocessing methods and cohort locations, are presented as relative abundances (%): Bacillota (median 49.5-59.6%), Bacteroidota (28.0-33.4%), Pseudomonadota (3.4-5.9%), Actinomycetota (2.3-3.7%), Verrucomicrobiota (0.5-1.0%), Fusobacteriota (maximum 4.6%), and Euryarchaeota (maximum 2.11%). The content of 27 key family-level representatives was also evaluated. The well-known hypothesis regarding the influence of the homogenization stage on taxonomic composition was examined using generalized results.
CONCLUSION: While supported by a strong theoretical basis and evidence from individual practical cases, none of the phyla showed a statistically significant association and consistent relationship with sample preparation or cohort location when generalizing across studies after the two exceptionally large cohorts exclusion, both originating from a single research group. These findings underscore the need for strict methodological standardization in microbiome studies. Key features of the 16S NGS process accounting for these results are outlined, along with proposed optimizations for microbiome research.

Engineered bacteria as living therapeutics: Next-generation precision tools for health, industry, environment, and agriculture.
AIMS microbiology, 11(4):946-962.
Synthetic biology has revolutionized precision medicine by enabling the development of engineered bacteria as living therapeutics, dynamic biological systems capable of sensing, responding to, and functioning within complex physiological environments. These microbial platforms offer unprecedented adaptability, allowing for real-time detection of disease signals and targeted therapeutic delivery. This review explores recent innovations in microbial engineering across medical, industrial, environmental, and agricultural domains. Key advances include CRISPR-Cas systems, synthetic gene circuits, and modular plasmid architectures that provide fine-tuned control over microbial behavior and therapeutic output. The integration of computational modeling and machine learning has further accelerated design, optimization, and scalability. Despite these breakthroughs, challenges persist in maintaining genetic stability, ensuring biosafety, and achieving reproducibility in clinical and industrial settings. Ethical and regulatory frameworks are evolving to address dual-use concerns, public perception, and global policy disparities. Looking forward, the convergence of synthetic biology with nanotechnology, materials science, and personalized medicine is paving the way for intelligent, responsive, and sustainable solutions to global health and environmental challenges. Engineered bacteria are poised to become transformative tools not only in disease treatment but also in diagnostics, biomanufacturing, pollution mitigation, and sustainable agriculture.

Methods and early findings from a study comparing next-generation sequencing versus traditional cultures for penile implants concerning for low-grade infection.
Translational andrology and urology, 14(12):3945-3951.
Microbial culture is the current standard of care to choose therapeutic antibiotics for infection occurring with inflatable penile prostheses (IPPs). However, next-generation sequencing (NGS) of DNA has proven beneficial for analysis of biofilm composition and relative abundance of specific microorganisms. The main goal of this study is to evaluate whether NGS compared to microbial culture can better guide the management and antibiotic selection and device survival rates. We hypothesize that identifying microbial composition with NGS, as compared with traditional culture, will lead to better therapeutic strategies resulting in improved patient outcomes and device survival. In this present manuscript, we describe the overall study methodology and analyze device survival rates, classify clinical presentations of IPP infections, and determine infected implant microbial composition and antibiotic resistance among an early patient cohort. These early results included 18- to 80-year-old consecutive male patients who received antimicrobial treatment without surgical replacement for at least 7 days since identification of infected IPPs. Subjects were randomized into two analytic arms: traditional culture and NGS. Throughout the study, investigators and patients completed questionnaires to provide data for comparison. To date, of the 9 patients enrolled in the study, 6 eventually underwent device removal due to worsening infection within 7 days of initiating empiric antibiotic treatment. Six patients were seen in a clinic setting, while 3 were seen in the hospital/emergency department: 7 implants were primary, while 2 were secondary. All subjects received a Coloplast IPP but had differing reservoirs and reservoir locations. In cases where penile shaft tenderness was present, the implanted IPP was more often removed within 7 days. In contrast, when no tenderness was reported, the device remained viable for at least 10 days. As of this report, 11 active sites have participated in the study, with ongoing patient enrollment aimed at reaching sufficient sample sizes for statistical comparison. Penile shaft tenderness was a common presentation among patients whose early antibiotic treatment for IPP infection failed. Recruitment of additional patients to this prospective, randomized controlled trial will help to identify favorable presentations of IPP infection. Additional data will allow comparison of implantation outcomes between NGS and traditional culture.

Plastics have become integral to modern life, but their persistence has generated vast quantities of microplastics (MPs, <5 mm) and nanoplastics (NPs, <1 µm) that now contaminate food, water, air, and human tissues. Although not yet classified as carcinogens by the International Agency for Research on Cancer, accumulating experimental and epidemiologic evidence raises concern that MPs may contribute to cancer development. Global plastic production has risen from 2 megatons in 1950 to more than 450 megatons annually in 2022, leaving behind pervasive waste that fragments into MPs and NPs. These particles act as xenobiotics, carrying toxic additives and adsorbed pollutants, provoking oxidative stress, chronic inflammation, DNA damage, and microbiome disruption; all processes central to carcinogenesis. MPs have been detected in human cancers, and animal studies show tissue accumulation, fibrosis, and genomic instability following exposure. Importantly, the proliferation of plastics parallels a global rise in early-onset cancers (diagnosed before age 50), suggesting a possible, though unproven, temporal association. Individuals born after the 1950s plastic boom have experienced continuous MP exposure beginning in utero, potentially predisposing them to carcinogenic pathways later in life. In this review, we integrate human biomonitoring data, experimental findings, and clinical observations to evaluate the emerging hypothesis that chronic MP exposure contributes to cancer risk. While causality has not been established, the biological plausibility and mounting evidence underscore the urgent need for mechanistic and epidemiologic studies to clarify the role of MPs and NPs in cancer development. It also underscores an urgent need for research into causal pathways and preventive mechanisms.

Metagenomic Insights on the Progression of White Muscle Disease in Kuruma Shrimp (Penaeus japonicus) Caused by Photobacterium damselae subsp. damselae.
Journal of fish diseases [Epub ahead of print].
Kuruma shrimp (Penaeus japonicus) is an economically important shrimp perennially affected by diseases. In 2022, White Muscle Disease (WMD) was first characterised in this Penaeid species, caused by Photobacterium damselae subsp. damselae (Pdd). In this study, muscular and gut microbiome dynamics and their function in the disease progression are investigated by 16S rRNA metagenome sequencing using Illumina sequencing technologies. Alpha diversity indices showed that Pdd infection in the muscle, stomach, and intestine did not significantly change bacterial diversity between control and infected groups at all time points observed (Days 0, 1, 3, 5, 7 and 10). In the infected samples, the Shannon and Simpson indices increased starting Day 5 (D5), in congruence with the first observation of muscle whitening. Bacterial composition for the infected group at the genus level revealed that Photobacterium and Vibrio have increased their relative abundance in the muscle at Day 5 (D5) until Day 7 (D7), but declined at Day 10 (D10). As for stomach samples, Photobacterium declined in abundance and later increased significantly at Day 7 (D7). Photobacterium in the intestinal samples from the infected group increased at Day 5 (D5) but later decreased at Day 7 (D7). Meanwhile, linear discriminant analysis Effect Size (LEfSe) identified that most taxa belong to phylum Pseudomonadota, which can be potential markers for WMD. Moreover, the temporal dynamics of the amplicon sequencing variant ASV2, confirmed to be 100% homologous to the WMD-P3 strain used in this study, were characterised. For all tissues, the logarithmic relative abundance is considered high and very apparent in infected samples collected at Day 7 (D7). Overall, our study provides an understanding of the muscle and gut microbial community, specifically at the genus level, distinguished between WMD-infected and healthy Kuruma shrimps.

Consensus guidelines for antibacterial prophylaxis in patients with neutropenia.
Internal medicine journal, 55 Suppl 7:115-135.
Since the publication of the Australian consensus guidelines in 2011, the routine use of prophylactic antibiotics in patients with neutropenia has remained controversial, because of concern that the risks of promoting antimicrobial resistance outweighed the level of evidence that their use reduced mortality. Populations at risk have changed over this period and now include a multitude of new cancer therapies, such as targeted cancer therapies and immunotherapies. Emerging understanding about the importance and role of the microbiome in defining treatment response and patterns of antibiotic resistance has also expanded. In addition, the management of neutropenic fever has improved significantly through the development and routine implementation of sepsis pathways. These updated consensus guidelines review recent evidence for the use of antibacterial prophylaxis in adults and children receiving cancer therapies associated with neutropenia. Recommendations presented in these guidelines were based on evaluating current evidence for the benefits and harms of antibacterial prophylaxis while considering the current Australian and New Zealand healthcare setting. In most circumstances, the potential harm of antibiotic resistance, adverse effects of antibiotics and disruption to the microbiome, outweighed the benefit of reducing the incidence of infection, without a benefit in mortality.

Consensus guidelines for initial management of neutropenic fever.
Internal medicine journal, 55 Suppl 7:43-67.
This update of the Australasian consensus guidelines for the initial empiric management of neutropenic fever occurs in the context of major changes in cancer treatment paradigms, as well as advances in the management of sepsis and new models of care for infections since the last version of these guidelines in 2011. Acknowledging the important role of antimicrobials in the disruption of the gut microbiome and emerging antimicrobial resistance, as well as the changing epidemiology of antimicrobial resistance more broadly, these guidelines address current evidence for optimal empiric neutropenic fever therapy. A writing group - including adult and paediatric representatives across infectious diseases, microbiology, haematology, transplant and oncology, as well as across craft groups, including medicine, nursing and pharmacy - was developed to produce and address key management questions. This was overseen by a steering committee, which included consumer representation. Using an extensive review of the literature, these guidelines provide consensus recommendations with evidence grading for initial empiric management of neutropenic fever in adults and children, including recommended investigations, antimicrobial therapy and approach to patients with beta-lactam allergy or risk factors for multidrug-resistant infection. Management beyond the first 72 h is discussed in separate chapters of this issue: the Subsequent Management (for high-risk neutropenic fever) and Ambulatory Management (for low-risk neutropenic fever) chapters.

Washed microbiota transplantation relieves atopic dermatitis via gut-skin microbiome rebalancing.
BMC microbiology pii:10.1186/s12866-026-04717-1 [Epub ahead of print].
BACKGROUND: Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease in which dysbiosis of gut and skin microbiota contributes to pathogenesis and severity. Washed microbiota transplantation (WMT)-an improved form of fecal microbiota transplantation with enhanced safety and microbiota quality control-has shown efficacy in a single reported adolescent case. However, clinical data on WMT in AD and its effects on the skin and gut microbiota remain limited.
METHODS: Twenty-three patients with moderate-to-severe AD received at least two courses of WMT between January 2022 and December 2023. Disease activity was evaluated using the SCORing Atopic Dermatitis (SCORAD) index, the Eczema Area and Severity Index (EASI), the Numeric Rating Scale (NRS) for itch, and the Dermatology Life Quality Index (DLQI). Peripheral blood counts, cytokine profiles, lymphocyte subsets, and gut and skin microbiota were assessed before and after treatment.
RESULTS: WMT was well tolerated (58 sessions; 5.2% mild adverse events) and significantly improved SCORAD, EASI, DLQI, and NRS scores, with greater EASI reductions in adults than in children. Absolute basophil counts decreased significantly after treatment, whereas other hematologic and cytokine parameters remained stable. Gut microbiota showed an increased Gut Microbiome Health Index, a decreased Microbial Dysbiosis Index, and enrichment of short-chain fatty acid-producing taxa, including the Eubacterium coprostanoligenes group, Lachnospiraceae, and Coprococcus. Skin microbiota shifted from Staphylococcus dominance to higher abundances of Acinetobacter, Perlucidibaca, and other potentially protective genera, inversely correlating with disease severity and systemic inflammation.
CONCLUSIONS: WMT appears safe and effective in alleviating clinical manifestations of AD while reshaping both gut and skin microbiota. These parallel microbial shifts support the gut-skin axis as a therapeutic target and highlight WMT as a promising microbiota-centered intervention for immune-mediated skin diseases.

Early-life supplementation of poultry-derived lactobacilli drives microbial succession and gut immune modulation in broiler chickens.
Scientific reports pii:10.1038/s41598-026-35177-2 [Epub ahead of print].
While probiotic supplementation via feed or drinking water is well known to improve poultry gut health by modulating the microbiota and enhancing immune function, the effects of in ovo supplementation remain largely unexplored. In this study, we investigated the effects of administering a lactobacilli cocktail in ovo (embryonic day 18), post-hatch, and in combination on gut immunity and the succession of the cecal microbiota in broilers over 5 weeks. 16S rRNA gene-based sequencing of cecal contents revealed a steady increase in Shannon diversity during the first 2 weeks (PERMANOVA, p < 0.005), with community structure stabilizing by week 3 across all groups. In ovo administration of lactobacilli improved early hatch rates and modulated microbial composition during early succession, including reductions in Klebsiella and Enterococcus, and enrichment of Lactobacillus, during the first two weeks (MaAsLin2, q < 0.25). These microbiome shifts were accompanied by a reduction in the expression of the pro-inflammatory cytokines, including interferon gamma (IFN-γ), interleukin-1β (IL-1β), and IL-8 in the cecal tonsils. These findings highlight the transient yet critical role of early-life probiotic interventions in shaping gut microbial colonization and immune response in broiler chickens. More importantly, a single in ovo lactobacilli dose yielded effects comparable to weekly oral or combined administration.

The effects of the Caribbean medicinal plant Argemone mexicana on Gardnerella vaginalis using a co-culture method with vaginal Lactobacillus spp.
Scientific reports pii:10.1038/s41598-025-26731-5 [Epub ahead of print].
Bacterial vaginosis (BV) is caused by vaginal microbiome dysbiosis, when beneficial Lactobacillus species are no longer dominant and are replaced by harmful anaerobic bacteria such as Gardnerella vaginalis. In Caribbean cultures, women use plants topically, such as Argemone mexicana, to treat several vaginal infections, including BV. There has been little research into how traditional botanical extracts affect the vaginal microbiota, especially as these extracts are often prepared in different ways for the same condition. This study aims to evaluate the effect of botanical preparations using an in vitro co-culture assay with beneficial Lactobacillus species and BV-causing Gardnerella vaginalis. This is an application of an in vitro co-culture assay to assess the effect of botanical preparations on the vaginal microbiota. We hypothesized that variations in the chemical composition of these preparations would affect the composition of vaginal microbiota. Argemone mexicana extractions were tested using an in vitro co-culture method with Gardnerella vaginalis and one of three vaginal Lactobacillus species and evaluated by UPLC-qToF-MS for metabolomic chemical analysis. Aqueous extractions that did not have significant antibacterial effect compared to the control in monoculture suppressed the growth of Gardnerella vaginalis in co-culture with Lactobacillus, supporting the traditional Dominican use of this plant. These results are likely related to the presence of berberine and polysaccharides in the aqueous extractions.

Integrating Perspectives on Aging: From Mechanistic Causes to Therapeutic Interventions.
Aging poses one of the most urgent biomedical challenges of the 21st century, increasing vulnerability to chronic diseases and limiting healthspan in aging populations. Recent advances in aging research are transforming our understanding of aging from an inevitable decline to a multidimensional and potentially modifiable biological process. This special issue presents five invited reviews that collectively illustrate the recent progress in aging research. These articles introduce emerging concepts that shed light on the fundamental causes of aging, including the genetic architecture underlying human aging, senescence-driven fibrotic scarring arising from imperfect tissue repair, and the progressive erosion of epigenetic information in the brain. They further highlight promising avenues for intervention-such as epigenetic rejuvenation, the bidirectional interplay between the aging gut microbiome and host physiology, and the emergence of precision geronutrition. By integrating genetic, molecular, cellular, microbial, and nutritional perspectives, this collection emphasizes a future where extending human healthspan is both realistic and scientifically attainable.

Microbiome-Modulated Immunotherapy in Oncology: Current Applications and Future Prospects.
Seminars in cancer biology pii:S1044-579X(26)00007-6 [Epub ahead of print].
Cancer immunotherapy has transformed oncology, yet therapeutic efficacy remains heterogeneous and frequently limited by primary or acquired resistance. Increasing evidence demonstrates that both intra- and extratumoral microbiota critically modulate antitumor immunity, influencing clinical responses of immunotherapy and immune-related adverse events (irAEs). Microbial communities regulate the tumor immune microenvironment through multiple mechanisms, including microbe-associated molecular patterns, microbial metabolites, and outer membrane vesicles, acting on tumor or immune cells. These insights have fostered the development of microbiome-based applications in oncology, ranging from predictive biomarkers to therapeutic interventions such as engineered bacteria, fecal microbiota transplantation, probiotics, prebiotics, outer membrane vesicles, bacteriophages, and dietary modulation. Early-phase clinical studies indicate that microbiota-targeted strategies can enhance immunotherapy efficacy or mitigate irAEs, although strain specificity, interindividual variability, and safety remain significant challenges. Future progress will require mechanistic elucidation, integration of multi-omics analyses, standardization of methodologies, and personalized intervention frameworks to translate microbiome modulation into clinically actionable, precision immunotherapy.

The Role of the Gut Microbiome in Childhood Obesity: Mechanistic Insights and Community-Based Interventions.
Clinical nutrition ESPEN pii:S2405-4577(26)00006-9 [Epub ahead of print].
Childhood obesity remains a critical issue, yet traditional efforts focusing on diet and exercise have failed. This review proposes that gut microbiota dysbiosis is not an association, but rather a potentially causal and actionable mechanism underlying childhood obesity. An altered gut microbiome, defined by diminished diversity and specific changes, such as a higher Firmicutes/Bacteroidetes ratio, is a primary contributor to excess weight because of its ability to enhance energy overconsumption, dysregulate production of short-chain fatty acids, regulate appetite, and induce chronic low-grade inflammation. This overview seeks to provide a synthesis of mechanistic evidence and controversies of the gut microbiome as a targetable leverage point, by assessing the microbial signatures of obesity and reflect on the evidence to date and what it implies about the effort: A quest for a singular "obesity microbe" is unlikely to provide success. The unexplained complexity of the host and environment, the lack of a high-quality standard, and evidence of functional microbial pathways and metabolites provide a more fruitful focus. Among other things, this article suggests using high-fiber, whole food dietary strategies to modify the microbiome, the targeted use of evidence-based multi-strain probiotics, and designing school and public health policies to create protective microbiome public health policies. The childhood obesity demands that future efforts focus on the integration of large, multi-omic, longitudinal studies, and the implementation of high-fidelity long-term randomized controlled trial designs that establish the causative relationships, uniform structure to the protocols and enable the implementation of high-impact, equity-based, scalable precision nutrition methodologies.

A multi-target therapeutic framework for Alzheimer's disease: an integrative mechanistic review.
Neuroscience pii:S0306-4522(26)00016-3 [Epub ahead of print].
BACKGROUND: Alzheimer's disease (AD) is increasingly recognized as a multifactorial network disorder in which amyloid and tau pathology interact with mitochondrial dysfunction, neuroinflammation, metabolic impairment, vascular dysregulation, and synaptic failure. This review provides an integrative, systems-level synthesis of these mechanisms with emphasis on diagnostic and therapeutic implications.
METHODS: A structured narrative review was conducted using PubMed, Scopus, Web of Science, and Embase (2010-2025). Eligible studies included clinical trials, biomarker validation studies, cohort analyses, and mechanistic investigations. Evidence was synthesized by mechanistic domain with focus on cross-system interactions and translational relevance.
FINDINGS: Convergent data indicate that soluble Aβ species, tau propagation, glial dysregulation, insulin resistance, mitochondrial bioenergetic failure, lipid imbalance, and BBB dysfunction form a self-reinforcing neurodegenerative network. Diagnostic advances-including plasma p-tau181/217, Aβ42/40 ratio, GFAP, sTREM2, neuronal exosomes, and multimodal machine-learning models-enable earlier staging and refinement of therapeutic selection. Therapeutic development is shifting from linear amyloid removal to multi-target strategies incorporating anti-tau agents, glial-modulating compounds, metabolic and microbiome interventions, medical nutrition, and multidomain lifestyle programs. Across trials, combined strategies targeting interacting mechanisms demonstrate stronger biomarker and cognitive effects than single-axis approaches.
CONCLUSIONS: AD management requires a systems-oriented therapeutic architecture in which interventions are selected based on mechanistic dominance, biomarker stage, and potential synergy. We outline a multi-target strategy integrating amyloid/tau modulation, neuroimmune regulation, metabolic-vascular stabilization, and synaptic support. Future work should prioritize biomarker-guided stratification, treatment sequencing, and prevention-oriented combination designs.

Unlocking therapeutic impacts of the gut microbiota with computational tools.
Current opinion in biotechnology, 97:103431 pii:S0958-1669(25)00175-2 [Epub ahead of print].
The human gut microbiota, particularly the intestinal microbiota, shapes host physiology, disease risk, and therapeutic outcomes through complex metabolic and enzymatic activities. Recent advances in molecular omics, metabolomics, enzyme bioinformatics, and artificial intelligence (AI) have created unprecedented opportunities to elucidate its therapeutic roles to further enable precision microbiome medicine for personalized prevention, diagnosis, and treatment. In this review, we highlight emerging applications that leverage molecular omics and metabolomics technologies to dissect gut microbial functions, along with developments in enzyme bioinformatics and AI tools that reveal gut microbial species, enzymes, and metabolic pathways impacting human health. Finally, we discuss perspectives on data standardization, functional annotation, and interpretability, and how emerging tools are accelerating translational microbiome research.

Neuroendocrine signaling as a pathological seed for the female bias of Alzheimer's disease and the concept of estrobolome.
Biomedicine & pharmacotherapy = Biomedecine & pharmacotherapie, 195:118999 pii:S0753-3322(26)00031-4 [Epub ahead of print].
The prevalence of Alzheimer's disease (AD) is anticipated to escalate with the global increase in life expectancy. Although sex-based differences in AD have been previously documented, doubts persist regarding the relationship between sex and pathophysiological pathways. Sex hormones may contribute to these disparities, with a heightened risk of AD-related dementia associated with oophorectomy before menopause. We cannot ascertain if estrogens alone are solely accountable for this accelerated pathological progression of the disease. Estrogens are regulated by the gut microbiota. Thus, the gut-estrogen-brain axis appears to be implicated as a potential new influencer in the pathophysiology of AD, as the female microbiome differs from the male gut microbiome. This suggests it could be a risk factor for the higher prevalence of AD in women. This review speculates on the possible mechanisms for AD prevalence in women, including both anatomical and neuroendocrinological perspectives.

Rumen microbiome biogeography and ventral epithelial architecture in three ruminant species.
Cell reports, 45(1):116779 pii:S2211-1247(25)01551-7 [Epub ahead of print].
Ruminants thrive in diverse ecosystems by leveraging their rumen microbiome to ferment fibrous plants. However, the spatial biogeography of rumen microbiome and the genetic diversity of the ventral rumen epithelium remain unknown. Here, we present a multi-omics study in roe deer, sika deer, and sheep, integrating region-resolved microbiome and metabolome across 11 ruminal sacs, as well as single-cell RNA sequencing (scRNA-seq), assay for transposase-accessible chromatin using sequencing (ATAC-seq), and bulk RNA sequencing (RNA-seq) of ventral epithelium. We reveal species-specific microbial compositions and metabolic capacities contributing to differences in short-chain fatty acid and vitamin B production. We uncover functional divergence, genomic specialization, and metabolic changes across the microbiome of distinct ruminal sacs. Single-cell profiling reveals changes of immune responses and structural remodeling of the ruminal ventral epithelium. We demonstrate that vitamin B12 promotes epithelial growth and we identify genes enhancing stem cell differentiation. Our results highlight variation in microbial ecology and epithelial architecture among three ruminant species, offering insights to improve livestock productivity.

Prior high fiber intake impinges on the cellular responses of mesenteric adipose and intestinal tissues to subsequent high fat feeding.
Cell reports, 45(1):116801 pii:S2211-1247(25)01573-6 [Epub ahead of print].
While high-fiber diets (HfiDs) promote weight loss, their long-term efficacy is limited by rapid weight regain upon returning to high-fat diets (HFDs). Using C57BL/6J mice in diet-switching paradigms, we characterized tissue-specific responses to HfiD-to-HFD transitions through single-nucleus and spatial transcriptomics. HfiD pre-feeding enhanced mesenteric white adipose tissue progenitor/adipocyte sensitivity to subsequent HFD exposure. In the intestine, HfiD prevented HFD-induced immune-enterocyte expansion in the duodenum and reversed the enterocyte-to-goblet cell shift in the colon while maintaining persistent epigenetic reprogramming. Although HfiD-induced microbiome changes were largely reversed by HFD, we identified sexually dimorphic remodeling of adipose cell populations during diet transitions. Our findings demonstrate that prior HfiD feeding fundamentally reprograms adipose and intestinal responses to subsequent HFD challenge, providing mechanistic insights into dietary intervention outcomes. This work establishes a spatiotemporal resource for understanding tissue plasticity during dietary changes, offering new perspectives for obesity management strategies.

Comparative efficacy of hyperthermic chemotherapy and BCG instillation in non-muscle invasive bladder cancer: a systematic review and meta-analysis.
International urology and nephrology [Epub ahead of print].
OBJECTIVE: To systematically evaluate the comparative efficacy and safety of hyperthermic intravesical chemotherapy (HIVEC) versus bacillus Calmette-Guérin (BCG) instillation in patients with non-muscle-invasive bladder cancer (NMIBC).
METHODS: A systematic literature search was conducted across PubMed, Embase, the Cochrane Library, and CBM from inception to June 30, 2025, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The study protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) under registration number CRD420251075299. Randomized controlled trials and cohort studies comparing HIVEC with BCG in NMIBC patients were included. Primary outcomes were 24-month recurrence-free survival (RFS), progression-free survival (PFS), and overall survival (OS). Secondary outcomes included adverse events. Risk ratios (RRs) or hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled using fixed- or random-effects models.
RESULTS: Seven studies involving 820 patients were included. The meta-analysis showed no significant differences between HIVEC and BCG in 24-month RFS (RR = 1.01, 95% CI: 0.90-1.12), PFS (RR = 1.00, 95% CI: 0.95-1.05), or OS (RR = 0.99, 95% CI: 0.91-1.09). However, BCG was associated with a significantly higher incidence of dysuria (RR = 1.38, 95% CI: 0.57-3.37). No significant differences were observed in other adverse events such as urinary tract infection, hematuria, or pain.
CONCLUSION: HIVEC demonstrates comparable oncological efficacy to BCG in terms of 24-month RFS, PFS, and OS for NMIBC patients, while offering a better tolerability profile with a significantly lower risk of dysuria. These findings support HIVEC as a valuable alternative treatment option, particularly in the context of BCG shortages or for BCG-intolerant patients.

MBRA 3.0: integrating the mucus environment for advanced high-throughput in vitro intestinal microbiome modeling.
Gut microbes, 18(1):2612804.
The colonic mucus layer is a dynamic barrier that plays central roles in intestinal health, and recent studies highlight that it harbors a distinct and functionally critical microbial community. However, most in vitro gut models fail to recapitulate this mucosal niche, limiting mechanistic investigation of microbiota-mucus interactions. Here, we developed the MBRA 3.0 system, a next-generation chemostat engineered to integrate mucus-coated carriers and enable high-throughput dissection of spatial microbiome dynamics. Using fecal microbiota from eight human donors, we report that mucus addition does not impact total bacterial density but selectively shapes microbial community structure, metabolic output, and pro-inflammatory potential in a donor-dependent manner. Notably, MBRA 3.0 resolves stable, compositionally distinct mucus-associated and luminal communities, mirroring in vivo spatial heterogeneity. Integration of this mucosal niche also modulates short-chain fatty acid (SCFA) profiles and inflammatory signatures, highlighting the relevance of the spatial context for intestinal microbiota research. Hence, MBRA 3.0 offers a scalable and customizable platform to model mucus-microbiota interactions, advancing our understanding of gut ecology and supporting translational discovery in gastrointestinal health and disease.

The human gut microbiome in enteric infections: from association to translation.
Gut microbes, 18(1):2612836.
Enteric infections remain a leading global cause of morbidity, mortality and economic loss, increasingly compounded by the rise of antimicrobial resistance. The gut microbiome - spanning bacteria, archaea, fungi, protists and viruses - is now recognized as an important mediator that shapes susceptibility to infection, pathogen expansion and disease severity through mechanisms such as colonization resistance, resource competition and immune modulation. Conversely, the gut microbial community can facilitate enteric infection through other processes such as cross-feeding and horizontal gene transfer. In this review, we synthesize correlative and mechanistic evidence currently available on microbiome-pathogen interactions; outline host, environmental and socioeconomic modifiers that affect disease risk across the life course; and evaluate current clinical applications. We highlight key limitations in the field and identify priority areas for future research to refine causal models of microbiome-pathogen ecology and enable targeted diagnostics and therapeutics for preventing and managing enteric infections.

abstract = {Enteric infections remain a leading global cause of morbidity, mortality and economic loss, increasingly compounded by the rise of antimicrobial resistance. The gut microbiome - spanning bacteria, archaea, fungi, protists and viruses - is now recognized as an important mediator that shapes susceptibility to infection, pathogen expansion and disease severity through mechanisms such as colonization resistance, resource competition and immune modulation. Conversely, the gut microbial community can facilitate enteric infection through other processes such as cross-feeding and horizontal gene transfer. In this review, we synthesize correlative and mechanistic evidence currently available on microbiome-pathogen interactions; outline host, environmental and socioeconomic modifiers that affect disease risk across the life course; and evaluate current clinical applications. We highlight key limitations in the field and identify priority areas for future research to refine causal models of microbiome-pathogen ecology and enable targeted diagnostics and therapeutics for preventing and managing enteric infections.},

Comparative insights into the gut-heart axis: cross-species and cross-population perspectives.
Gut microbes, 18(1):2611617.
Gut microbiota research has rapidly expanded our understanding of host-microbe interactions in cardiovascular diseases, yet translation of these insights remains challenged by species-specific differences and substantial population heterogeneity. In this review, we synthesize current evidence across rodents, swine, non-human primates, and multi-ethnic human cohorts to delineate conserved versus context-dependent features of the gut-heart axis. Rodent models remain indispensable for mechanistic discovery, enabling causal testing through germ-free, antibiotic-treated, and humanized microbiota platforms, whereas large-animal models better replicate human cardiac anatomy, physiology, and microbial ecology. Human studies provide essential clinical relevance, demonstrating that patients with myocardial infarction, coronary artery disease, atrial fibrillation, and heart failure harbor distinct microbial and metabolite signatures. However, these findings vary across populations due to differences in diet, lifestyle, host genetics, medication exposure, and environmental transitions. Despite taxonomic variability, several functional pathways, most notably short-chain fatty acid production, bile acid biotransformation, and aromatic amino acid metabolism generating molecules such as trimethylamine-N-oxide and phenylacetylglutamine, consistently associate with cardiovascular risk. At the same time, population-specific features, including glycan-microbe interactions shaped by ABO and FUT2 genotypes, diet-responsive metabolite profiles, and variable drug-microbiome interactions, highlight the importance of genetic and environmental context. By integrating cross-species and cross-population evidence, this review outlines a framework for identifying robust microbial pathways, clarifying their translational boundaries, and guiding the development of microbiota-informed diagnostics and interventions that account for biological, cultural, and environmental diversity.

Discordance between preoperative urine culture and intraoperative stone/pelvis culture as a predictor of post-PCNL sepsis: a single-center retrospective analysis for targeted antibiotic stewardship.
International urology and nephrology [Epub ahead of print].
PURPOSE: To evaluate the diagnostic accuracy of preoperative midstream urine culture (PMUC) against intraoperative stone and pelvic urine cultures, and to determine if culture discordance independently predicts sepsis following percutaneous nephrolithotomy (PCNL).
METHODS: This retrospective cohort study analyzed 250 adult patients undergoing PCNL between January 2023 and October 2025. All participants had both PMUC and intraoperative stone/pelvic urine cultures. The primary outcome was post-PCNL sepsis defined by Sepsis-3 criteria. Diagnostic performance metrics were calculated, and the association between discordance and sepsis was assessed using multivariable logistic regression, LASSO penalization, and propensity-score matching to adjust for confounders.
RESULTS: Culture discordance was observed in 30% (75/250) of patients. The sensitivity of PMUC for detecting upper urinary tract colonization was only 48%. Sepsis occurred in 6.8% of the total cohort but was significantly more frequent in the discordant group (17.3 vs 2.3%, p < 0.0001). In multivariable analysis, discordance remained the strongest independent predictor of sepsis (adjusted OR 6.23, 95% CI 2.20-17.62, p < 0.001), displacing stone burden and operative time. Notably, patients with sterile preoperative urine but positive intraoperative cultures accounted for 92.3% of sepsis events within the discordant group.
CONCLUSION: PMUC is an unreliable surrogate for the upper tract microbiome, failing to detect colonization in over half of cases. Culture discordance is a robust predictor of post-PCNL sepsis, driven by untreated bacterial biofilms within stones. Routine intraoperative culturing is essential for targeted antibiotic stewardship to mitigate septic complications.

Changes in gut, microbiome, and cognition after doxorubicin, cyclophosphamide, and paclitaxel chemotherapy treatment.
Scientific reports pii:10.1038/s41598-025-33903-w [Epub ahead of print].
Over 317,000 new cases of breast cancer will be diagnosed in 2025, making it the most diagnosed cancer among women in the United States. Advancements in treatment options such as chemotherapy and radiation have resulted in a 5-year survival rate of 91%. Upwards of 78% of the 4.1 million breast cancer survivors currently living in the United States report chemotherapy induced cognitive impairment (CICI), or "chemobrain". CICI defined as an impairment in memory, learning, executive function, and attention following chemotherapy treatment. There is a need for a better understanding of the long-term side effects of these treatments and the impact these may have on the quality of life for these survivors. In this study, we used a translational mouse model to study cognitive decline via intraperitoneal injections of the combination chemotherapy AC-T: Doxorubicin (DOX), Cyclophosphamide (CYP), and Paclitaxel (PTX). Mice underwent behavior tests to assess social memory and anxiety 30 days after the last AC-T injection. AC-T treated mice revealed behavioral deficits in social memory and an increase in anxiety-like behavior. RNA-sequencing and western blot analysis revealed negatively altered expression of transcripts associated with neurogenesis, axonal guidance, neurotransmission, and protein IEGs such as Arc, c-Fos, and Egr-1, respectively. Proteomics indicated increases in inflammatory markers in intestinal tissue, which also coincided with changes in intestinal morphology of AC-T treated mice. The gut microbiota of AC-T treated mice showed became dysbiotic. This study provides a multi-omic overview of the effects of AC-T treatment on cognition and intestinal inflammation and morphology.

Arctic Insects Show a Highly Dynamic Microbiome Shaped by Abiotic and Biotic Variables.
Microbial ecology pii:10.1007/s00248-025-02685-z [Epub ahead of print].
Arctic regions are inhabited by terrestrial ectotherms that have adapted to an extreme environment where food resources are limited. The host associated microbiome may partly explain their ability to live under these conditions, but very little is known about the microbiome of Arctic ectotherms. We investigate how the bacterial community of the Greenlandic seed bug (Nysius groenlandicus) and damsel bug (Nabis flavomarginatus) is affected by different abiotic and biotic factors (time, acclimation temperature, humidity, and diet) under both field and laboratory conditions. We found large differences in the bacterial composition and diversity between the two species including species-specific presence of potentially symbiotic bacteria. The bacterial community of both species changed across the season, which may be explained by the changing climatic conditions, such as temperature and humidity. This was further supported by results from the laboratory experiments. We also found that diet changed the bacterial composition in both species and that bacteria could be transferred from prey to predator. Together, these results show that the bacterial community of some Arctic insects are highly dynamic and modulated by different abiotic and biotic factors, suggesting that the microbiome plays an important role for these organisms to persist in an extreme and resource-limited Arctic environment.

The gut microbial profile and circulating metabolism are associated with functional constipation in children.
Pediatric research [Epub ahead of print].
BACKGROUND: A growing body of evidence highlights the link between gut microbiome imbalances and constipation. However, the role of gut microbiota and its metabolic interactions in pediatric functional constipation (FC) remains incompletely understood.
METHODS: We recruited a total of 40 children with FC and 40 healthy children (CONT). 16SrRNA and metagenomic sequencing were used to evaluate the changes in the gut microbiota structure and gene function in FC patients. Differences in serum metabolite levels were analyzed via targeted metabolomic sequencing.
RESULTS: The FC group exhibited a decrease in gut microbiota diversity, an increase in Bacteroides and Prevotella abundances, depletion of genera such as Lactobacillus and Bifidobacterium and an imbalance of related metabolic activities. Metabolomic analysis revealed that the levels of several metabolites, including taurine and glycochenodeoxycholic acid, which are involved in bile acid (BA) metabolic pathways, differed between the FC and CONT groups. Differences in metabolite levels were associated with changes in the abundances of specific bacteria and with intestinal dysfunction in FC patients.
CONCLUSION: FC in children is associated with distinct gut microbiota alterations and dysregulated BA metabolism. These findings provide potential therapeutic targets for modulating the gut microbiome and metabolic pathways in FC management.
IMPACT: This study offers a comprehensive perspective on the intricate relationship between microbial composition and metabolic pathways in the context of functional constipation in children. This study focuses on children, highlighting how disruptions in bile acid metabolism due to gut microbiota disorders are linked to the occurrence of functional constipation. These findings suggest that disturbances in bile acid metabolism may play a role in the mechanisms underlying functional constipation by impairing intestinal secretion and transport functions. This study offers a new way to study the effects of the gut microbiota, bile acid metabolism, and the gut‒brain axis.

Effects of cigarette smoking on the oral microbiome in adolescents.
Scientific reports, 16(1):1348.
Smoking, a risk factor for periodontitis and peri-implantitis, is associated with shifts in the oral microbiome (OM) composition. Although smoking habits are almost always established before adulthood, data on effects of smoking on the OM in adolescents is rare. The aim of this study was to investigate the early impact of smoking on the OM composition in pupils. The adolescent cohort, aged 14-20, comprised 98 smokers and 98 non-smokers matched for several physiological co-variates. Buccal swabs were analysed for OM composition using high-throughput sequencing of the full-length 16 S rRNA gene targeting species-level resolution. Parameters of bacterial diversity and abundance of individual bacterial taxa were related to information on smoking. The microbiome dataset contained 733 species-level taxa. Streptococcus, Rothia, and Haemophilus dominated both groups, smokers and non-smokers. Smoking exerted a discernible influence on the overall microbial composition as measured by weighted UniFrac distances. The number of species-level bacterial taxa was significantly higher in individual smokers compared to non-smokers. Furthermore, several taxa, including known pathogens, exhibited significant differences in abundance between the two groups. The genera Veillonella, and Actinomyces, as well as and multiple Actinomyces species, Dialister invisus, Atopobium parvulum, Streptococcus mutans and Prevotella melaninogenica were significantly more abundant in smokers. Our findings indicated an early onset of smoking-related changes already in the oral microbiome of adolescents.

Malabsorption Syndromes and Risk of Age-Related Macular Degeneration: Evidence from Real-World Data.
Ophthalmology. Retina pii:S2468-6530(26)00002-3 [Epub ahead of print].
PURPOSE: Despite mechanistic links connecting malnutrition and gut microbiome with retinal health, clinical research exploring the relationship between malabsorption syndromes and age-related macular degeneration (AMD) remains limited. This study compared the risks of AMD diagnosis in patients with and without various malabsorption syndrome diagnoses.
DESIGN: Retrospective cohort study of aggregated, de-identified patient data from multiple healthcare organizations across the United States using the TriNetX U.S. Collaborative Research Network in 11/2025.
PARTICIPANTS: Adults with a cataract-related International Classification of Diseases (ICD) encounter diagnosis codes and no baseline AMD ICD encounter diagnosis codes were divided into groups based on the presence of ICD encounter diagnosis codes for celiac disease (CeD), ulcerative colitis (UC), Crohn's disease (CrD), chronic pancreatitis (CP), and short bowel syndrome (SBS). Within the CP cohort, patients with pancreatic enzyme replacement therapy (PERT) prescription orders were subanalysis. For each cohort, a corresponding control cohort of patients without the respective ICD encounter diagnosis codes was created.
METHODS: The study and control cohorts were propensity-matched 1:1 on demographic factors, comorbidities, and disease-related conditions and prescription orders. The matched cohorts were compared on the risk of having AMD ICD encounter diagnoses.
MAIN OUTCOME MEASURE: Risk ratios (RR) and 95% confidence intervals (CI) of having an AMD ICD encounter diagnosis code with an accompanying retinal optical coherence tomography Common Procedural Terminology code. Significance was defined as CI ≤0.9 or ≥1.1.
RESULTS: Compared to controls without IBD, the CrD cohort (n=9,537, RR=1.42, CI=1.16-1.74), but not the UC cohort (n=15,039, RR=1.28, CI=1.09-1.51), had a higher risk of having early/intermediate AMD. CP was associated with an increased risk of AMD (n=12,856, RR=1.82, CI=1.53-2.16), even in the PERT subset (n=3,812, RR=1.83, CI=1.35-2.48). SBS (n=3,747) was associated with an increased risk of advanced/exudative AMD (RR=1.98, CI=1.31-2.98), but not early/intermediate AMD (RR=1.28, CI=0.96-1.71). CeD was not associated with increased AMD risk (n=9,315, RR=1.09, CI=0.88-1.35).
CONCLUSIONS: Chronic non-infectious causes of malabsorption syndromes-CrD, CP, and SBS-may represent underrecognized risk factors of AMD. This explorative study adds clinical evidence for a potential role of the gut-retina axis in the pathogenesis of AMD.

abstract = {PURPOSE: Despite mechanistic links connecting malnutrition and gut microbiome with retinal health, clinical research exploring the relationship between malabsorption syndromes and age-related macular degeneration (AMD) remains limited. This study compared the risks of AMD diagnosis in patients with and without various malabsorption syndrome diagnoses.
DESIGN: Retrospective cohort study of aggregated, de-identified patient data from multiple healthcare organizations across the United States using the TriNetX U.S. Collaborative Research Network in 11/2025.
PARTICIPANTS: Adults with a cataract-related International Classification of Diseases (ICD) encounter diagnosis codes and no baseline AMD ICD encounter diagnosis codes were divided into groups based on the presence of ICD encounter diagnosis codes for celiac disease (CeD), ulcerative colitis (UC), Crohn's disease (CrD), chronic pancreatitis (CP), and short bowel syndrome (SBS). Within the CP cohort, patients with pancreatic enzyme replacement therapy (PERT) prescription orders were subanalysis. For each cohort, a corresponding control cohort of patients without the respective ICD encounter diagnosis codes was created.
METHODS: The study and control cohorts were propensity-matched 1:1 on demographic factors, comorbidities, and disease-related conditions and prescription orders. The matched cohorts were compared on the risk of having AMD ICD encounter diagnoses.
MAIN OUTCOME MEASURE: Risk ratios (RR) and 95% confidence intervals (CI) of having an AMD ICD encounter diagnosis code with an accompanying retinal optical coherence tomography Common Procedural Terminology code. Significance was defined as CI ≤0.9 or ≥1.1.
RESULTS: Compared to controls without IBD, the CrD cohort (n=9,537, RR=1.42, CI=1.16-1.74), but not the UC cohort (n=15,039, RR=1.28, CI=1.09-1.51), had a higher risk of having early/intermediate AMD. CP was associated with an increased risk of AMD (n=12,856, RR=1.82, CI=1.53-2.16), even in the PERT subset (n=3,812, RR=1.83, CI=1.35-2.48). SBS (n=3,747) was associated with an increased risk of advanced/exudative AMD (RR=1.98, CI=1.31-2.98), but not early/intermediate AMD (RR=1.28, CI=0.96-1.71). CeD was not associated with increased AMD risk (n=9,315, RR=1.09, CI=0.88-1.35).
CONCLUSIONS: Chronic non-infectious causes of malabsorption syndromes-CrD, CP, and SBS-may represent underrecognized risk factors of AMD. This explorative study adds clinical evidence for a potential role of the gut-retina axis in the pathogenesis of AMD.},

Alterations in cardiovascular biomarkers and gut microbiome associated with night shift work: Insights from the Chinese Platform Workers Study.
Environmental research pii:S0013-9351(26)00063-0 [Epub ahead of print].
The expansion of the gig economy has been marked by an increase in platform workers, including ride-hailing drivers, who typically work non-standard schedules, with night shifts being common. Although night shift work was known to disrupt circadian rhythms and elevate cardiovascular risks, the interplay between early alteration in cardiovascular biomarkers and gut microbiome remain unclear. To investigate these associations in the platform worker groups, we conducted a cross-sectional study comparing 66 night shift and 175 day shift ride-hailing drivers in Beijing, China. All participants underwent health examinations, provided blood tests for the assessment of four key cardiovascular biomarkers (hs-cTnI, ET-1, NT-pro-BNP, and FABP-3), and submitted fecal samples for gut microbiome profiling via 16S rDNA sequencing. Bioinformatics, linear regression, and mediation analyses were conducted to evaluate the associations between night shift work, biomarkers, and microbial taxa, with adjustments for key sociodemographic and lifestyle factors. Night shift drivers exhibited significantly higher levels of NT-pro-BNP (median 49.8 vs. 41.3 pg/ml, P = 0.044), an association that remained significant after adjustment for covariates (β = 0.195, P = 0.004). Twenty differentially abundant taxa were identified, four of which were significantly associated with hs-cTnI. No significant mediation effect was observed. This study found that night shift work in ride-hailing drivers was significantly associated with adverse cardiovascular biomarker profiles and distinct gut microbiome alterations. Correlation analysis further suggested that gut microbial changes were linked to the observed cardiovascular risk. This study reported associations between night-shift work and alterations in early cardiovascular injury biomarkers as well as the gut microbiota, suggesting a potential link between gut microbiota and night-shift-related cardiovascular injury.

Fibrinogen-Associated Plasma Metabolites and Implications for Coagulation, Inflammation, and Vascular Diseases.
Journal of thrombosis and haemostasis : JTH pii:S1538-7836(26)00005-X [Epub ahead of print].
BACKGROUND: Fibrinogen is a critical coagulation factor that plays an essential role in thrombosis and is elevated in individuals with chronic inflammation. Here, we used fibrinogen as a representative quantitative measure of pro-coagulant risk and evaluated metabolites associated with fibrinogen levels through non-targeted plasma metabolomic profiling (Broad and Metabolon platforms).
METHODS: Our analysis included 10,533 individuals across six U.S. based cohorts representing diverse population groups. The cross-sectional relationship between each of 789 tested metabolites and plasma fibrinogen concentration was assessed with adjustment for relevant covariates such as age, sex, body mass index, and circulating lipoprotein levels.
RESULTS: Meta-analysis of per-cohort results revealed 270 metabolites significantly associated with fibrinogen level (FDR adjusted p-value < 0.05). Lipid species such as glycerophospholipids, sphingolipids, and fatty acyls were prevalent among significantly associated metabolites; some of these may capture effects of inflammation, as supported by sensitivity analyses adjusted for C-reactive protein. Significant associations between fibrinogen levels and serotonin, thyroxine, and sex-hormone derivatives may capture endogenous influences on fibrinogen levels. Exogenous compounds and microbial co-metabolites significantly associated with fibrinogen also implicate lifestyle and microbiome risk-factors. Only a portion of fibrinogen-associated metabolites (30%) have been associated with a cardiovascular disease outcome in a prior study, suggesting the associations discovered here may provide insights on vascular biology which case-control studies may not yet be powered to detect.
CONCLUSIONS: These findings contribute to a growing list of metabolite biomarkers that may influence coagulation and inflammation pathways and may thereby contribute to vascular risk.

Dietary Ethanolamine Increases Hepatic Lipid Accumulation in Mice Fed a High Fat Diet.
The Journal of nutrition pii:S0022-3166(25)00854-5 [Epub ahead of print].
BACKGROUND: Ethanolamine (Etn), a precursor of phosphatidylethanolamine (PE), may alter hepatic lipid homeostasis and gut health; its dietary effects remain undefined.
OBJECTIVE: To determine the effects of dietary Etn on lipid and glucose metabolism and liver/gut health in high-fat diet (HFD)-fed mice, complemented by in vitro hepatocyte assays.
METHODS: Ten-week-old C57BL/6 mice (20 male, 18 female) were fed ad libitum HFD (45% energy from fat) with (ES) or without (CON) Etn (8 g/kg diet) for 10 weeks. Outcomes included body/liver weight, glucose tolerance (GTT), plasma PC/CE/TG, hepatic TG/PC/PE, hepatic ER-stress and inflammation markers, jejunal morphology/barrier/inflammation genes, and fecal microbiota (α/β diversity). HuH7 cells received 20 μM or 5 mM Etn to assess TG/PC/PE synthesis.
STATISTICS: repeated-measures ANOVA (GTT), t-test or Wilcoxon (other endpoints), PERMANOVA (β diversity); α=0.05.
RESULTS: ES increased hepatic TG in females by 230% vs CON (p = 0.001), and trended higher in males (p = 0.054); hepatic PC and PE masses were unchanged. In ES-males, GTT AUC decreased by 22.6% (p = 0.037), and plasma PC, CE, and TG were reduced by: PC - 16.6%, CE - 24.5%, TG - 25.9% (all p < 0.05). ES males showed higher hepatic Tnf and Cd68 and increased CHOP protein (all p < 0.05). In vitro, Etn did not alter hepatocellular TG, PC, or PE synthesis (all p > 0.05). Female ES mice exhibited altered fecal β-diversity (PERMANOVA p = 0.006) with early jejunal inflammatory signals (Tnf ↑; p = 0.055).
CONCLUSIONS: Dietary Etn modifies hepatic lipid storage and gut microbiota in a sex-dependent manner and improves glucose tolerance in males, whereas in vitro data indicate no direct effect on hepatocyte lipid synthesis.

The Central Qi Theory in Traditional Chinese Medicine: Gut Microbiota Modulation as a Strategic Target for Hepatocellular Carcinoma Therapy.
Journal of ethnopharmacology pii:S0378-8741(25)01840-9 [Epub ahead of print].
Patients with intermediate and advanced hepatocellular carcinoma (HCC) often derive limited benefit from systemic therapy and experience a substantial symptom burden with deterioration in quality of life. These challenges underscore the need for safe, effective adjunctive or alternative therapies. The traditional Chinese medicine concept of Central Qi shows conceptual contemporary with contemporary understanding of the gut-liver axis and microbiome biology. Chinese herbal medicines centered on tonifying the central and replenishing qi (Buzhong Yiqi) are considered adjunctive or alternative therapeutic options for alleviating symptoms, improving quality of life, and enhancing tolerance and adherence to standard treatments.
AIM OF THIS REVIEW: To delineate links among the interrelations among Central Qi, the gut microbiota, and HCC, to synthesize evidence on how Buzhong Yiqi medicines modulate the gut microbiota, and to elucidate the proposed mechanistic bases for their potential adjunctive effects in HCC. This review aims to provide a biologically plausible framework to inform microbiome-based mechanistic research and clinical translation.
METHODS: Databases including PubMed, Web of Science, Elsevier ScienceDirect, CNKI, and Google Scholar were searched using predefined terms related to hepatocellular carcinoma, gut microbiota, and the gut-liver axis, nutrient absorption, metabolic regulation, immune modulation, and Buzhong Yiqi medicines, as well as their representative herbs. In vivo, in vitro, and clinical studies published from 2000 to October 2025 were included.
RESULTS: Dysbiosis disrupts the metabolic pathways of bile acid, short-chain fatty acid, and tryptophan metabolic pathways, while compromising the intestinal barrier. This disruption can worsen appetite regulation and energy imbalance, as well as weaken antitumor immunity. Buzhong Yiqi medicines have been reported to enrich beneficial taxa, reduce pathogens and pathobionts, and improve microbial metabolite profiles, restoration of barrier integrity, improvements in nutrient intake and energy homeostasis. These findings are heterogeneous and largely derived from non-HCC models, but collectively suggest potential support of metabolic and immune homeostasis, with possible influence on the tumor immune microenvironment. Early exploratory data also indicate a potential interaction with immune checkpoint inhibitors, although its clinical significance remains uncertain.
CONCLUSION: Central Qi deficiency provides a biologically plausible conceptual framework linking impaired digestion, disrupted energy metabolism, microbial dysbiosis, and reduced immune responsiveness in HCC. Modulation of the GM through Buzhong Yiqi medicines may offer supportive metabolic and immunological benefits, but current evidence is preliminary, based mainly on associative findings, and requires cautious interpretation. Key uncertainties remain regarding causal relationships, HCC-specific mechanisms, and the consistency of clinical effects. Future research should prioritize standardized preparations, mechanistic validation, biomarker-guided stratification, and rigorously designed clinical trials to clarify the clinical relevance of these proposed pathways and to advance global acceptance of integrative therapy.

Microbial communities in filth flies collected from dairy and poultry farms for supplemental animal feed.
Journal of economic entomology pii:8419819 [Epub ahead of print].
Alternative protein sources are needed due to the rising demand and increasing cost of protein ingredients in livestock diets. Mass collection of wild-caught flies from locations with high insect pressure may be an economical and environmentally sustainable approach to supplement livestock feed, but there may be feed safety issues from microbes found in field-caught insects. Therefore, we evaluated a sequencing-based approach to accurately identify potential pathogens in wild-caught flies captured on 2 different livestock farms. In this study, we combined whole-genome shotgun metagenomic sequencing with total RNA-seq to identify a broad range of microbial taxa present in and on wild-caught flies. We describe several databases tailored to the host insect, host animals, and pathogens associated with livestock and humans. Sequences were identified from potentially pathogenic bacteria including Escherichia coli, Gallibacterium anatis, Helicobacterium pullorum, Morganella morganii, Proteus mirabilis, and Providencia alcalifaciens. In addition, sequences from the pathogenic fungi Aspergillus fumigatus and viruses such as the fly pathogen Musca hytrosavirus were found. Despite the limitations of current database curation, a combination of metagenomics and total RNA-seq approaches to taxa identification can provide insight into a broad spectrum of potential pathogens in insects used as supplemental livestock feed.

Microbiota and infertility: a translational review of mechanisms and clinical applications in assisted reproduction.
European journal of obstetrics, gynecology, and reproductive biology, 318:114941 pii:S0301-2115(26)00007-2 [Epub ahead of print].
Infertility constitutes a major global health concern, affecting approximately 17.5% of couples of reproductive age. Although advances in assisted reproductive technologies (ART) have expanded treatment options, success rates remain highly variable due to host-specific and biological determinants. This review synthesizes current evidence on the reproductive impact of the human microbiota and its translational relevance to ART outcomes. Vaginal microbial communities dominated by Lactobacillus, particularly L. crispatus, are associated with improved conception and implantation, whereas genital or intestinal dysbiosis correlates with infertility and suboptimal treatment responses. The microbiota modulates reproductive competence through intertwined immune, endocrine-metabolic, and mucosal barrier pathways that regulate inflammation, hormonal balance, and epithelial integrity. Emerging findings indicate that gut microbial alterations linked to polycystic ovary syndrome (PCOS) and endometriosis are accompanied by insulin resistance and chronic inflammation, impairing ovulation, endometrial receptivity, and embryo viability. Interventions such as probiotics and synbiotics yield heterogeneous efficacy; individualized antimicrobial strategies, metabolic modulation, and lifestyle optimization may offer complementary benefit, while microbiota reconstruction remains experimental. Methodological limitations, including contamination in low biomass samples, variations in sequencing workflows, and population heterogeneity, still hinder data comparability and mechanistic interpretation. Future research should prioritize adequately powered randomized controlled trials using standardized microbiome metrics and live birth as a primary endpoint. Integrating microbiome profiling into ART workflows may refine patient stratification and inform precision adjuvant therapies. However, clinical implementation requires stronger causal evidence, validated biomarkers, and harmonized methodological frameworks to translate microbiome discoveries into reproducible reproductive gains.

Molecular community data meets anaerobic digestion Model 1 (ADM1) - a study about the correlation between metagenome-centric metaproteomics data of a two-step full-scale anaerobic digester and its corresponding mathematical model.
Water research, 292:125272 pii:S0043-1354(25)02173-6 [Epub ahead of print].
Advanced models, such as the Anaerobic Digestion Model No 1 (ADM1), are essential for operating, planning, and optimizing renewable energy production in anaerobic digester plants (AD-P)s. In this study, the ADM1da model was employed to simulate a two-step AD-P in an industrial setting. The ADM1da model is an extended ADM1 model for mixed substrates, accounting for substrate-specific disintegration, temperature effects, biogas-related mass reduction, and mineral solids content. ADM1 models can represent the anaerobic digestion processes, although the biological assumptions are coarse and reflect the knowledge and available tools for microbial communities at the time of development. Meanwhile, metagenome-centric metaproteomics provides deeper insight into the metabolic activities of microbial communities in AD-Ps. Until now, this data has not been integrated with ADM1 models. The objective of this study is to assess the feasibility of incorporating metagenome-centric metaproteome data into the ADM1 model. In a novel approach, 49 high-quality metagenome-assembled genomes (MAGs) with associated protein abundances were systematically classified into the trophic groups defined by the ADM1 model using specifically developed grouping rules. Abundances of MAGs were more variable than the process parameter-dependent dynamics of ADM1. Depending on the grouping rules, 32%-78% of all high-quality MAGs were successfully categorized into ADM1 trophic groups. However, some MAGs, e.g., Methanotrix, were multifunctional (acetoclastic and hydrogenotrophic methanogenesis) and required assignment to multiple groups. Unfortunately, more precise grouping rules resulted in greater discrepancies between metaproteomics data and the model. Additionally, 22% of the MAGs could not be assigned. The metagenome-centric metaproteome data imply that ADM1 probably needs extension to cover the observed microbial function of syntrophic acetate oxidizers, hydrolytic bacteria, lactate- and ethanol-fermenting bacteria, and mortality by phages. It was also observed that changes in process parameters, such as those caused by seasonal feeding, led to significant changes in the protein abundance Integrating metagenome-centric metaproteomic data into ADM1 trophic groups was shown to be feasible.Some trophic groups detected in protein data but not implemented in ADM1 imply the need for data-driven model enhancement and approval. In the future, more accurate models considering molecular data could support a deeper understanding of microbial community dynamics in AD-Ps.

Codonopsis pilosula regulates pathogen defense mechanisms through collaboration of root volatile compounds and microbial interactions.
Plant physiology and biochemistry : PPB, 231:110974 pii:S0981-9428(25)01502-5 [Epub ahead of print].
Codonopsis pilosula responds to pathogen infection by modulating root volatile organic compounds (VOCs) and reshaping the rhizosphere microbiome. GC-IMS analysis linked root VOCs with microbial community composition, showing positive correlations with Bradyrhizobium and beneficial fungi, and negative associations with Alternaria pathogens. Representative VOCs-benzothiazole, linalool, and (E,E)-2,4-heptadienal-showed significant antifungal activity against Fusarium oxysporum. Molecular docking and qPCR analyses indicate that these compounds may interact with stress-related proteins and potentially influence autophagy-associated pathways, suggesting stress responses that could contribute to fungal growth inhibition or cell death. Although autophagy was not directly demonstrated, these findings highlight VOCs as important mediators of plant defense signaling and may support the development of eco-friendly VOC-based antifungal strategies.

Multi-omics assessment of synthetic microbiome-mediated remediation of cyclotetramethylene tetranitroamine (HMX) contaminated water.
Journal of hazardous materials, 503:141026 pii:S0304-3894(26)00004-X [Epub ahead of print].
Cyclotetramethylene tetranitroamine (HMX) is a typical high-energy nitramine pollutant with an environmental persistence and toxic effects that pose serious ecological risks. In this study, a synthetic microbiome with complementary functions is built that enables the integration of multigroup technology to conduct a systematic analysis of the mechanism of remediation of HMX-contaminated water bodies. Four core bacterial strains (Bacillus altitudinis, B. cereus, B. subtilis, and Pseudomonas stutzeri) were directionally domesticated and screened from HMX-contaminated water. Through functional verification, they were confirmed to express key enzymes NfsA, YdhA, FdhA, and NirS, respectively, to form a complete HMX deep degradation-level connection path. The synthetic microbiome achieved 100 % removal of HMX and its intermediates within 60 days, and isotope tracing (δ[15]N enrichment +2.7 ‰) confirmed its complete mineralization ability. Multiomic analysis showed that the restoration process is accompanied by a systematic reshaping of the water microecology and chemical environment, so that the microbial community structure is optimized and the synthetic microbiome is successfully colonized and becomes the core node. Meanwhile, the energy metabolic network (glycolysis, TCA cycle, oxidative phosphorylation) is significantly enhanced; metagenomic data also revealed reduced viral abundance. Ionomics revealed that key nutrient elements, such as P and S, are efficiently assimilated and utilized. These findings identify an efficient HMX bioremediation strategy that utilizes the multiple dimensions of "community structure-metabolic function-environmental effects" through a multigroup integration framework. More importantly, this study provides a theoretical basis and practical paradigm for the rational design of functional microbial communities.

The Role of the Gut Microbiome in the Complex Network of Frailty Syndrome and Associated Comorbidities in Aging.
Aging cell, 25(2):e70365.
The gut microbiota changes throughout life, potentially influencing health and triggering physiological disorders. Frailty syndrome (FS) is an age-related condition that reduces quality of life and increases hospitalization and mortality risks, making early detection and prevention essential in older populations. This study analyzed 16S rRNA gene and metagenomics sequencing of fecal samples from 203 older adults (FS: n = 64, non-FS (NFS): n = 139) to assess the role of gut microbiota in FS and related comorbidities, such as sarcopenia and impaired lower extremity function (ILEF) or anthropometric variables. Consistent taxonomic patterns were observed: Eggerthella, Parabacteroides, and Erysipelatoclostridium were significantly abundant in FS, while Christensenellaceae R-7 group, Erysipelotrichaceae UCG-003, and Hungatella were enriched in NFS. Christensenellaceae R-7 group was also associated with better mobility. Metagenomics analysis identified 680 KEGG functions differing between groups, categorized into 28 metabolic pathways. FS individuals had overrepresented biotin metabolism, antimicrobial resistance, and energy production, but underrepresented ribosomal and protein synthesis and sporulation pathways. Resistome analysis found the tetM/tetO (K18220) gene most abundant, alongside tetracycline, β-lactam, and macrolide resistance, primarily mediated by antibiotic efflux and transporters. These findings highlight distinct microbial and functional signatures associated with FS, underscoring the complex interplay between the gut microbiota and host physiology in aging. Adjusting for covariates, age and diabetes acted as confounding factors in FS for both 16S gene and metagenomics sequencing. This study offers new insights into fundamental questions in the biology of aging and opens avenues for microbiota-targeted strategies to improve the quality of life in older adults.

The Oral Microbiome in Amyotrophic Lateral Sclerosis Shows Differentially Abundant Organisms in Limb Versus Bulbar Onset Disease: A Binational Study.
Journal of clinical neurology (Seoul, Korea), 22(1):66-75.
BACKGROUND AND PURPOSE: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease of upper and lower motor neurons leading to progressive disability and death. Approximately 10% of cases are caused by single-gene disorders with the remaining 90% of cases presumed to be caused by a combination of environmental and genetic factors. The microbiome (the ensemble of microorganisms that colonize body surfaces and organs) was recently identified for its importance in the pathogenesis of ALS.
METHODS: In this study, we recruited 100 participants from two ethnically and geographically distinct sites (71 from Calgary, Canada, and 29 from Seoul, Republic of Korea) which included 59 ALS participants and 41 controls. All participants provided saliva samples for oral microbial analysis using 16S rRNA sequencing. Basic demographic information was collected from all participants, and ALS participants provided additional clinical information including site of disease onset, disease duration, and ALS Functional Rating Scale - Revised score.
RESULTS: Significant differences in beta diversity of the oral microbiomes were seen between limb- and bulbar-onset ALS participants. Two bacterial genera were differentially abundant between these groups, Bifidobacteriaceae Bifidobacterium was enriched in bulbar-onset cases, while Pasteurellaceae Haemophilus was enriched in limb-onset cases. No significant differences were found between ALS participants and controls, but there were significant differences when comparing participants from different sites of recruitment. Amongst household pairs (n=35 pairs), ALS participants differed from control participants at the Seoul site.
CONCLUSIONS: Despite the cohort and household effects, our study identified differentially abundant organisms that may be important to the phenotypic variability of ALS and should be considered for future study. Our study provides novel insights into design for future multi-site microbiome research in ALS.

Five-Year Follow-Up of Photobiomodulation in Parkinson's Disease: A Case Series Exploring Clinical Stability and Microbiome Modulation.
Journal of clinical medicine, 15(1):.
Background: Parkinson's disease (PD) involves progressive neurodegeneration with clinical or subclinical disturbance of the gut-brain axis, including altered gastrointestinal motility and enteric nervous system involvement. Clinical studies have reported gut microbiome alterations in PD, with shifts in taxa associated with inflammatory signalling and short-chain fatty acid (SCFA) metabolism. Photobiomodulation (PBM), a non-invasive light therapy, has been investigated as a potential adjunctive treatment for PD, with proposed effects on neural, metabolic, and immune pathways. We previously reported the five-year clinical outcomes in a PBM-treated Parkinson's disease case series. Here we report the five-year gut microbiome outcomes based on longitudinal samples collected from the same participants. This was an exploratory, open-label longitudinal study without a control group. Objective: Our objective was to assess whether long-term PBM was associated with changes in gut microbiome diversity and composition in the same Parkinson's disease cohort as previously assessed for changes in Parkinson's symptoms. Methods: Six participants from the earlier PBM proof-of-concept study who had been diagnosed with idiopathic PD and who had continued treatment (transcranial light emitting diode [LED] plus abdominal and neck laser) for five years had their faecal samples analysed by 16S rDNA sequencing to assess microbiome diversity and taxonomic composition. Results: Microbiome analysis revealed significantly reduced evenness (α-diversity) and significant shifts in β-diversity over five years, as assessed by Permutational Multivariate Analysis of Variance (PERMANOVA). At the phylum level, Pseudomonadota and Methanobacteriota decreased in four of the six participants. Both of these phyla are often increased in the Parkinson's microbiome compared with the microbiomes of healthy controls. Family-level changes included increased acetate-producing Bifidobacteriaceae (five of the six participants); decreased pro-inflammatory, lipopolysaccharide (LPS)-producing Enterobacteriaceae (two of the three participants who have this bacterial family present); and decreased LPS- and H2S-producing Desulfovibrionaceae (five of six). At the genus level, Faecalibacterium, a key butyrate producer, increased in four of the six participants, potentially leading to more SCFA availability, although other SCFA-producing bacteria were decreased. This was accompanied by reductions in pro-inflammatory LPS and H2S-producing genera that are often increased in the Parkinson's microbiome. Conclusions: This five-year case series represents the longest follow-up of microbiome changes in Parkinson's disease, although the interpretation of results is limited by very small numbers, the lack of a control group, and the inability to control for lifestyle influences such as dietary changes. While causal relationships cannot be inferred, the parallel changes in improvements in mobility and non-motor Parkinson's symptoms observed in this cohort, raises the hypothesis that PBM may interact with the gut-brain axis via the microbiome. Controlled studies incorporating functional multi-omics are needed to clarify potential mechanistic links between microbial function, host metabolism, and clinical outcomes.

A Vanished Association Between Proton Pump Inhibitors and Clostridioides Difficile Infection After Minimizing Bias.
Journal of clinical medicine, 15(1):.
Background: The gut microbiome might be affected by proton-pump inhibitors (PPIs), increasing the risk of Clostridioides difficile infection (CDI); however, the association between PPIs and Clostridioides difficile infection (CDI) remains controversial. Aim: The aim of this study is to reevaluate the association between PPIs and CDI based on pharmacovigilance data, taking competition bias into account. Methods: PPI-related CDI adverse event reports, based on the Food and Drug Administration adverse event reporting system database from 2004 to 2023, were analyzed. Included PPI cases were stratified into CDI and non-CDI groups. Disproportionality analysis was performed using the reporting odds ratio (ROR) and information component (IC). The effect of competition bias on signal detection was quantitatively investigated. Age-stratified analyses were conducted to assess residual confounding. Results: A total of 238,470 PPI reports were included, with 1268 cases in the CDI group and 237,202 cases in the non-CDI group. Initial analysis revealed a significant PPI-CDI association (ROR = 2.36, 95% confidence interval (95%CI) 2.19 to 2.53; IC = 1.21, 95%CI 0.97 to 1.45), with CDI signals detected for five PPI agents, including pantoprazole, omeprazole, lansoprazole, rabeprazole, and dexlansoprazole. After excluding competition from antibacterial drugs, CDI signal strength decreased substantially (ROR = 1.47, 95%CI 1.34 to 1.62; IC = 0.55, 95%CI 0.23 to 0.87), retaining a significant CDI signal only for rabeprazole and pantoprazole. Upon further exclusion of antibacterial or immunosuppressive drug users and renal injury event cases, CDI signal strength decreased (ROR = 1.48, 95%CI 1.32 to 1.66; IC = 0.56, 95%CI 0.18 to 0.94), with pantoprazole as the sole CDI signal drug. Age-stratified analyses demonstrated complete signal loss after antibacterial drug adjustment across all age groups. Conclusions: The current large-scale pharmacovigilance study indicated that the observed PPI-CDI association may be mediated predominantly by antibacterial drug co-exposure rather than PPI direct causation.

Aim: The aim of this study is to reevaluate the association between PPIs and CDI based on pharmacovigilance data, taking competition bias into account. Methods: PPI-related CDI adverse event reports, based on the Food and Drug Administration adverse event reporting system database from 2004 to 2023, were analyzed. Included PPI cases were stratified into CDI and non-CDI groups. Disproportionality analysis was performed using the reporting odds ratio (ROR) and information component (IC). The effect of competition bias on signal detection was quantitatively investigated. Age-stratified analyses were conducted to assess residual confounding. Results: A total of 238,470 PPI reports were included, with 1268 cases in the CDI group and 237,202 cases in the non-CDI group. Initial analysis revealed a significant PPI-CDI association (ROR = 2.36, 95% confidence interval (95%CI) 2.19 to 2.53; IC = 1.21, 95%CI 0.97 to 1.45), with CDI signals detected for five PPI agents, including pantoprazole, omeprazole, lansoprazole, rabeprazole, and dexlansoprazole.

Combined Effect of Plasma-Activated Water, Edible Coating, and Active Packaging on Cherry Tomato Shelf-Life: Kinetics and Microbiome Approach.
Foods (Basel, Switzerland), 15(1):.
Cherry tomatoes are highly appreciated for their nutritional value but remain highly perishable due to rapid respiration and senescence. This study evaluated a multi-hurdle strategy combining plasma-activated water (PAW), sodium caseinate-based edible coating, and antioxidant active packaging to preserve minimally processed (MP) cherry tomatoes stored at 1 °C, 4 °C, and 8 °C for 15 days. Quality evolution was monitored through physical, chemical, nutritional, and microbiological parameters and described using pseudo-zero- and first-order kinetic models, with temperature dependence expressed by the Arrhenius equation. The combined treatment (prototype) slowed the degradation rates of pH, titratable acidity, total polyphenols, and antioxidant capacity, as reflected by consistently lower kinetic rate constants across all temperatures. Prototype samples showed better retention of polyphenols and antioxidant capacity, particularly at 1 °C and 4 °C, without detrimental effects on visual appearance. Metagenomic analysis revealed that the multi-hurdle treatment reshaped the microbial community, reducing the relative abundance of potentially problematic taxa such as Acinetobacter johnsonii and limiting the occurrence of antimicrobial resistance (AMR) genes at the end of storage. This study provides the first integrated assessment of PAW, edible coating, and antioxidant active packaging as a synergistic multi-hurdle strategy, demonstrating their combined ability to extend shelf life while modulating the microbiome and resistome of minimally processed cherry tomatoes.

Multi-Omics Analyses Unveil the Effects of a Long-Term High-Salt, High-Fat, and High-Fructose Diet on Rats.
Foods (Basel, Switzerland), 15(1):.
BACKGROUND: Unhealthy diets characterized by high salt, fat, and fructose content are established risk factors for metabolic and cardiovascular disorders and may have indirect effects on cognitive function. However, the combined impact of a high-salt, high-fat, and high-fructose diet (HSHFHFD) on systemic physiology and brain health remains to be fully elucidated.
METHODS: Sprague-Dawley (SD) rats received a customized high-salt, high-fat diet supplemented with 30% fructose water for 18 weeks. Physiological and brain parameters were assessed, in combination with multi-omics analyses including brain proteomics and metabolomics, serum metabolomics, and gut microbiota profiling.
RESULTS: HSHFHFD significantly elevated blood glucose, blood pressure, and serum levels of TG, TC, and LDL in rats. Serum metabolomic profiling identified over 100 differentially abundant metabolites in the Model group. Proteomics, metabolomics, and gut microbiome integration revealed pronounced alterations in both brain proteomic and metabolomic profiles, with 155 differentially expressed proteins associated with glial cell proliferation and 65 differential metabolites linked to fatty acid and amino acid metabolism, among others. Experimental validation confirmed marked upregulation of GFAP and Bax protein, concomitant with downregulation of ZO-1 and occludin. Furthermore, HSHFHFD perturbed the CREB signaling pathway, leading to diminished BDNF expression. The levels of inflammatory factors, including IL-6, IL-10, IL-1β and TNFα, were significantly elevated in the brain. Oxidative stress was evident, as indicated by elevated malondialdehyde (MDA) levels, increased superoxide dismutase (SOD) activity, and altered NAD[+]/NADH ratio. Additionally, HSHFHFD significantly reduced the abundance of beneficial gut bacteria, including Lactobacillus, Romboutsia, and Monoglobus.
CONCLUSIONS: HSHFHFD-induced depletion of gut Lactobacillus spp. may disrupt the linoleic acid metabolic pathway and gut-brain axis homeostasis, leading to the impairment of neuroprotective function, blood-brain barrier dysfunction, and exacerbated neuroinflammation and oxidative stress in the brain. These effects potentially increase the susceptibility of rats to neurodegenerative disorders.

Genetic Engineering and Encapsulation Strategies for Lacticaseibacillus rhamnosus Enhanced Functionalities and Delivery: Recent Advances and Future Approaches.
Foods (Basel, Switzerland), 15(1):.
This review addresses the recent advances made through various genetic engineering techniques to improve the properties of Lacticaseibacillus rhamnosus, not only for industrial applications, but also for the health-related benefits. However, due to the strict regulations on microorganisms intended for human consumption, concerning the insufficient characterization degree of the newly isolated strains and the lack of data regarding the safety of the genetically modified (GM) variants, the feasibility of bringing such L. rhamnosus strains to the market and their safety prospects were evaluated. Given their multiple in vivo functions in the contexts of synbiotic and symbiotic functionality, L. rhamnosus strains are more than classic probiotics and need furthermore attention. In the functional food context, this review highlights the impact of L. rhamnosus derived bioactives on the human gut-organ axis, pointing out recently demonstrated molecular mechanisms of action with the host's gut microbiome to reduce the negative effects of obesity and its related metabolic disorders, as well as depression and Parkinson's disease, as the major challenges confronting humans today. Beyond that, considering L. rhamnosus delivery and its postbiotics accessibility to consumers via functional foods, notable progress was made to enhance their stability by developing various encapsulation systems, which are also emphasized.

Integrative Analysis of Nutritional Components, Differential Metabolites, and Endophytic Microbiota Reveals Flavor Determinants of Lushan Russet Potato.
Foods (Basel, Switzerland), 15(1):.
The Lushan Russet potato, cultivated in Lushan Mountain (China), is renowned for its unique flavor, which deteriorates when cultivated at low altitudes. To unravel its flavor determinants, we compared high/low-altitude-cultivated Lushan Russet potato (LsM/LS) and reference Zhongshu5 (Zs) via nutritional, metabolomic, and endophytic microbiota analyses. LsM/LS had higher dry matter, potassium, and other flavor-related components than Zs. Non-targeted LC-MS metabolomics identified 461 metabolites. Pairwise comparisons revealed 263 significant differential metabolites (SDMs) between LsM and Zs (205 more abundant in LsM), 240 between LS and Zs, and 237 between LsM and LS. KEGG enrichment showed that SDMs were mainly involved in metabolic pathways. High-throughput sequencing of endophytic microbiota showed clear beta diversity separation, which correlated with metabolomic changes. These results indicate that Lushan Russet potato's unique flavor is jointly determined by nutrient/metabolite accumulation and endophytic microbiome diversity, providing a basis for optimizing its quality and mitigating flavor deterioration in low-altitude cultivation.

Artificial Intelligence-Driven Food Safety: Decoding Gut Microbiota-Mediated Health Effects of Non-Microbial Contaminants.
Foods (Basel, Switzerland), 15(1):.
A wide range of non-microbial contaminants-such as heavy metals, pesticide residues, antibiotics, as well emerging foodborne contaminants like micro- and nanoplastics and persistent organic pollutants-can enter the human body through daily diet and exert subtle yet chronic effects that are increasingly recognized to be gut microbiota-dependent. However, the relationships among multi-contaminant exposure profiles, dynamic microbial community structures, microbial metabolites, and diverse clinical or subclinical phenotypes are highly non-linear and multidimensional, posing major challenges to traditional analytical approaches. Artificial intelligence (AI) is emerging as a powerful tool to untangle the complex interactions between foodborne non-microbial contaminants, the gut microbiota, and host health. This review synthesizes current knowledge on how key classes of non-microbial food contaminants modulate gut microbial composition and function, and how these alterations, in turn, influence intestinal barrier integrity, immune homeostasis, metabolic regulation, and systemic disease risk. We then highlight recent advances in the application of AI techniques, including machine learning (ML), deep learning (DL), and network-based methods, to integrate multi-omics and exposure data, identify microbiota and metabolite signatures of specific contaminants, and infer potential causal pathways within "contaminant-microbiota-host" axes. Finally, we discuss current limitations, such as data heterogeneity, small-sample bias, and interpretability gaps, and propose future directions for building standardized datasets, explainable AI frameworks, and human-relevant experimental validation pipelines. Overall, AI-enabled analysis offers a promising avenue to refine food safety risk assessment, support precision nutrition strategies, and develop microbiota-targeted interventions against non-microbial food contaminants.

Global Research on Hemodialysis Nutrition and Patient-Centered Priorities: A Bibliometric Analysis (2006-2025).
Healthcare (Basel, Switzerland), 14(1):.
Background: Optimal nutritional care is essential to improving outcomes in hemodialysis, yet translation of evidence into routine practice remains uneven across settings. To inform health system planning and implementation priorities, we mapped global research on hemodialysis-related nutrition. Methods: We searched the Web of Science Core Collection for English-language original articles on nutrition and hemodialysis from 1 January 2006 to 13 October 2025. Publication trends, productivity by country and institution, influential journals and authors, citation impact, and conceptual structure via Keyword Plus co-occurrence, trend, and thematic evolution analyses were assessed using the bibliometrix package (version 5.0) in R. Results: A total of 332 articles from 115 journals were identified, with substantial growth and multidisciplinary authorship, though international collaboration remains limited. The United States contributed 21.4% of publications and achieved the highest citation impact, while China, Japan, Iran, and Brazil formed the next tier of contributors. The Journal of Renal Nutrition accounted for 16.6% of papers. Highly cited studies established links between dietary intake, mineral and electrolyte management, and survival, while supporting the use of intradialytic oral nutritional supplements. Thematic evolution showed a shift from biochemical markers toward patient-centered priorities, including diet quality, adherence, body composition, mental health, and quality of life. Emerging directions point to whole-diet approaches and microbiome-modulating strategies. Conclusions: Global research on diet and hemodialysis has progressed from foundational nutrient studies to multidimensional, patient-focused approaches. Our findings suggest opportunities for health systems to strengthen dietitian-led models of care, integrate patient-reported outcomes, and prioritize scalable nutrition interventions within routine dialysis services.

Emerging Insights into the Role of the Microbiome in Brain Gliomas: A Systematic Review of Recent Evidence.
International journal of molecular sciences, 27(1):.
Gliomas, particularly glioblastoma multiforme, remain among the most lethal brain tumours despite multimodal therapy. Increasing evidence indicates that systemic factors, including the gut microbiota, may influence glioma progression through immune, metabolic, and neurochemical pathways. We conducted a comprehensive systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines to synthesize recent evidence on the role of gut and intratumoral microbiota in glioma biology. Peer-reviewed studies published within the last five years were identified through structured searches of major biomedical databases, and original studies using human cohorts, animal models, or Mendelian randomization approaches were included. The 17 studies met the eligibility criteria. Glioma was consistently associated with gut dysbiosis characterized by a reduced Firmicutes:Bacteroidetes ratio and enrichment of Verrucomicrobia, particularly Akkermansia, alongside decreased short-chain fatty acids and altered neurotransmitter profiles, contributing to neuroinflammation, immune suppression, and blood-brain barrier dysfunction. Antigenic mimicry by Bacteroidetes-derived peptides may impair antitumour T-cell responses, while intratumoral Fusobacteriota and Proteobacteria appear to promote angiogenesis and pro-inflammatory chemokine expression. In contrast, SCFA-producing taxa such as Ruminococcaceae and probiotic genera including Lactobacillus and Bifidobacterium show protective associations. Evidence is limited by small cohorts and methodological heterogeneity. Standardized humanized models and integrated multi-omics approaches are required to clarify causal mechanisms and support microbiome-targeted therapies in glioma.

Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a disabling clinical condition, whose hallmark characteristic is post-exertional malaise (PEM). It can affect many organs and systems, leading to severe impairment of patients' quality of life. Although numerous post-infectious, immunological, neurological, metabolic, and endocrine alterations have been documented, neither a definitive diagnostic marker nor approved treatments are available. The etiology and pathophysiology remain incompletely understood; however, emerging evidence suggests that the gut microbiome plays a role in immune responses and the development of ME/CFS. It is hypothesized that specific disturbances in gut microbiome composition, known as dysbiosis, may compromise the integrity of the intestinal barrier. This consequently leads to translocation of microbial components, which further triggers an immune response and systemic inflammation complicating the clinical presentation of ME/CFS. Furthermore, in terms of the so-called gut-brain axis, microbiome changes may lead to distinct neurocognitive impairments observed in ME/CFS patients. This review offers the readers a broad perspective on the topic on ME/CFS, with a particular emphasis on the interplay between the gut microbiome and disease mechanisms. Last but not least, recent data on potential treatment strategies for intestinal dysbiosis in ME/CFS patients have been included.

More than Dysbiosis: Imbalance in Humoral and Neuronal Bidirectional Crosstalk Between Gut and Brain in Alzheimer's Disease.
International journal of molecular sciences, 27(1):.
The intestinal microbiota, a diverse community of microorganisms residing in the human gut, recently attracted considerable attention as a contributing factor to various neurological disorders, including Alzheimer's Disease (AD). Within the established framework of the gut-brain axis (GBA) concept, it is commonly suggested that dysbiosis, through microbial metabolites entering the brain, affect the cognitive functions in patients with AD. However, evidence for such a role of dysbiosis remains largely associative, and the complexity of the communication channels between the gut and the brain is not fully understood. Moreover, the new players of the GBA are emerging and the AD concept is constantly evolving. The objective of this narrative review is to synthesize the current evidence on the humoral, endocrine, immune, and neural communication mechanisms linking the gut and brain in AD and highlight newly discovered GBA messengers such as microRNAs, extracellular vesicles, T-cells, and the intestinal hormones, including emerging neuroprotective role for glucagon-like peptide-1 (GLP-1). Based on this knowledge, we aimed to develop a conceptual understanding of the GBA function in health and AD. We specify that, in AD, the GBA goes beyond a disrupted microbiome, but operates in conjunction with impaired intestinal secretion, motility, barrier permeability, and neuroinflammatory signaling. These factors are associated with the dysfunction of the hypothalamic-pituitary axis, altered somatic and autonomic neuronal gut regulation, and abnormal, due to memory problems, behavioral aspects of food intake. Identifying the individual profile of key molecular and cellular players contributing to an unbalanced GBA should optimize existing approaches or propose new approaches for the complex therapy of AD.

From Gut Dysbiosis to Skin Inflammation in Atopic Dermatitis: Probiotics and the Gut-Skin Axis-Clinical Outcomes and Microbiome Implications.
International journal of molecular sciences, 27(1):.
Atopic dermatitis (AD) is a chronic inflammatory skin disease in which barrier impairment, immune dysregulation, and gut-skin dysbiosis intersect, prompting growing interest in probiotics as microbiota-modulating adjuncts. We conducted a narrative review of peer-reviewed articles indexed in PubMed, Scopus, and Google Scholar, restricted to publications from 1 January 2018 to 31 October 2025 (searches last run in December 2025). Eligible evidence included randomized controlled trials (RCTs), observational studies, and mechanistic or conceptual reviews addressing microbiome alterations and microbiota-modulating interventions in AD. Most pediatric RCTs using multistrain, Lactobacillus-dominant formulations (often combined with Bifidobacterium) reported modest improvements in AD severity and pruritus and in selected barrier- and inflammation-related biomarkers. However, direct cutaneous microbiome "restoration" outcomes were reported in a minority of studies, and most clinical evidence relies on clinical endpoints and gut-skin axis plausibility rather than longitudinal skin microbiome readouts. Single-strain regimens showed inconsistent effects, and evidence in adolescents and adults remained heterogeneous. Mechanistically, probiotics may enhance short-chain fatty acid (SCFA) signaling, dampen toll-like receptor 2/4 (TLR2/4)-nuclear factor kappa B (NF-κB) activation, and promote interleukin-10 (IL-10)- and transforming growth factor-β (TGF-β)-driven tolerance. Probiotics are a biologically plausible adjunct targeting the gut-skin axis in AD and are generally well tolerated; however, heterogeneity across trials, limited follow-up, inconsistent adverse-event reporting, and scarce skin microbiome endpoints preclude firm clinical recommendations.

Exploring the Activity of a Novel N-Glycosidase (EndoBI-2): Recombinant Production to Release Bioactive Glycans.
International journal of molecular sciences, 27(1):.
The gut microbiome evolves in response to host development, health state, lifestyle, nutrition, and microbial interactions. The survival of gut microbiota depends on its ability to utilize its host-indigestible complex oligosaccharides. Certain gut microbes produce glycosidases that cleave N-glycoproteins to release N-glycans that are then used as a carbon source. However, commercial glycosidases are inefficient and, thus, require improved deglycosylation strategies to study their functions and scale up their production. Therefore, the main objective of this study was to recombinantly produce and characterize the novel endo-β-N-acetylglucosaminidase 2 (EndoBI-2) from Bifidobacterium longum subsp. infantis (B. infantis) and to evaluate its enzymatic performance for controlled N-glycan release. Furthermore, the optimum reaction conditions for EndoBI-2 were investigated on model glycoprotein RNAse B using model glycoprotein. The released N-glycans were profiled by hydrophilic interaction liquid chromatography-fluorescence detection-quadrupole time-of-flight tandem mass spectrometry (HILIC-FLD-QTOF-MS/MS). We demonstrated that EndoBI-2 possesses a strong temperature tolerance and efficiently cleaves N-glycans under mild reaction conditions, exhibiting high activity at pH 5. These findings highlight EndoBI-2 as a robust and efficient biocatalyst for the production of bioactive N-glycans from diverse N-glycoproteins, with potential applications in glycobiotechnology.

Genetic Characterisation of Closely Related Lactococcus lactis Strains Used in Dairy Starter Cultures.
International journal of molecular sciences, 27(1):.
The complex microbiota of cheese starters plays a key role in determining the structure and flavour of the final product, primarily through their acid-forming capacity, protease activity, and exopolysaccharide synthesis. However, the specific microbial communities underlying the unique qualities of artisanal cheeses remain poorly understood. This study presents the microbiological and molecular genetic characterisation of the microbiome isolated from an artisanal cheese starter in Kosh-Agach, Altai, Russia. Metagenomic analysis of this starter revealed the presence of three bacterial genomes corresponding to those of Lactococcus lactis. Pure cultures from this starter were obtained by sequential subculture, and seventeen colonies displaying distinct characteristics on differential media were selected. Genome sequencing was performed for each colony. Bioinformatic analysis based on the rpoB gene grouped the isolates into three clusters, each corresponding to a distinct strain of Lactococcus lactis subsp. diacetilactis. This classification was further confirmed by microbiological and microscopic analyses. A notable finding was that none of the strains produced the characteristic aroma compounds of L. l. subsp. diacetilactis, namely, diacetyl and CO2. The functional properties and metabolic characteristics of this starter consortium are discussed.

Effects of natural mono- and di-saccharide as alternative sweeteners on inflammatory bowel disease: a narrative review.
Korean journal of community nutrition, 28(3):181-191.
OBJECTIVES: The incidence of inflammatory bowel disease (IBD) is increasing globally, and excessive added sugar consumption has been identified as one of the contributing factors. In the context of IBD, it is essential to explore functional sweeteners that can improve metabolic health and minimize the risk of IBD-related symptoms. This review article aims to shed light on the effects of natural mono- and di-saccharides as alternative sweeteners, specifically focusing on potential benefits for IBD.
METHODS: A comprehensive literature review was performed using PubMed and Google Scholar databases with articles published after the year 2000. The search terms 'IBD', 'added sugar', 'sweeteners', 'mono-saccharide', and 'di-saccharide' were combined to retrieve relevant articles. A total of 21 manuscripts, aligning with the objectives of the study, were selected. Papers focusing on artificial or high-intensity sweeteners were excluded to ensure relevant literature selection.
RESULTS: Multiple studies have emphasized the association between the high consumption of added sugars such as simple sugars and the increased risk of developing IBD. This is suggested to be attributed to the induction of pro-inflammatory cytokine productions and dysbiosis of the gut microbiota. Consequently, there is a growing demand for safe and functional sweeteners, in particular mono- and di-saccharides, that can serve as alternatives for IBD patients. Those functional sweeteners regulate inflammation, oxidative stress, and Intestinal barrier protection, and restore microbiome profiles in various IBD models including cells, animals, and humans.
CONCLUSIONS: Understanding these mechanisms resolves the link between how sugar consumption and IBD, and highlights the beneficial effects of natural alternative sweeteners on IBD when they were administered by itself or as a replacement for simple sugar. Further, exploration of this relationship leads us to recognize the necessity of natural alternative sweeteners in dietary planning. This knowledge could potentially lead to more effective dietary strategies for individuals with IBD.

AI-Guided Multi-Omic Microbiome Modulation Improves Clinical and Inflammatory Outcomes in Refractory IBD: A Real-World Study.
International journal of molecular sciences, 27(1):.
Inflammatory bowel disease (IBD) remains difficult to manage in patients who fail multiple therapeutic lines, and growing evidence suggests that alterations in the gut microbiome contribute to persistent symptoms and inflammatory activity. This study evaluated a three-month, AI-guided, multi-omic personalized microbiome modulation program in adults with treatment-refractory IBD. Baseline stool metagenomic sequencing, blood biomarkers, micronutrient panels, and clinical data were integrated through an artificial intelligence platform to generate individualized plans combining dietary adjustments, targeted synbiotics, selective antimicrobials, and micronutrient correction. Clinical outcomes, inflammatory markers, and microbial signatures were reassessed after three months. Across 358 participants, stool frequency decreased substantially, urgency and rectal bleeding resolved in most patients, and over 70% reported a "much improved" overall condition. Inflammatory biomarkers showed marked normalization, with reductions in hs-CRP and fecal calprotectin observed in over 85% of cases. Micronutrient deficiencies, particularly iron and zinc, also improved, and beneficial microbial taxa such as Faecalibacterium prausnitzii, Bifidobacterium longum, and Akkermansia muciniphila increased significantly. These findings suggest that personalized, multi-omic microbiome modulation may support clinically meaningful improvements by targeting microbial, metabolic, and immune imbalances rather than symptoms alone. While encouraging, these results require confirmation in randomized controlled studies.

Oral and Gut Health, (Neuro) Inflammation, and Central Sensitization in Chronic Pain: A Narrative Review of Mechanisms, Treatment Opportunities, and Research Agenda.
International journal of molecular sciences, 27(1):.
Given the limited efficacy of current interventions and the complexity of chronic pain, identifying perpetuating factors is crucial for uncovering new mechanistic pathways and treatment targets. The oral and gut microbiome has emerged as a potential modulator of pain through immune, metabolic, and neural mechanisms. Contemporary evidence indicates that chronic pain populations exhibit altered oral and gut microbiota, characterized by reduced short-chain fatty acid (SCFA)-producing taxa and an overrepresentation of pro-inflammatory species. These compositional changes affect metabolites such as SCFAs, bile acids, and microbial cell wall components, which interact with host receptors to promote peripheral and central sensitization. Microbiota-derived metabolites modulate peripheral sensitization by altering nociceptive neuron excitability and stimulating immune cells to release pro-inflammatory cytokines that increase blood-brain barrier permeability, activate microglia, and amplify neuroinflammation. Activated microglia further disrupt the balance between excitatory and inhibitory neurotransmission by enhancing glutamatergic activity and weakening GABAergic signaling, thereby contributing to the induction and maintenance of central sensitization. While observational studies establish associations between dysbiosis and chronic pain, animal models and early human fecal microbiota transplantation studies suggest a potential causal role of dysbiosis in pain, although human evidence remains preliminary and influenced by diet, lifestyle, and comorbidities. Overall, microbiota appears to regulate pain via peripheral and central mechanisms, and targeting it through specific interventions, such as dietary modulation to enhance SCFA production, alongside broader lifestyle measures like sleep, physical activity, stress management, and oral hygiene, may represent a new therapeutic strategy for the management of chronic pain.

abstract = {Given the limited efficacy of current interventions and the complexity of chronic pain, identifying perpetuating factors is crucial for uncovering new mechanistic pathways and treatment targets. The oral and gut microbiome has emerged as a potential modulator of pain through immune, metabolic, and neural mechanisms. Contemporary evidence indicates that chronic pain populations exhibit altered oral and gut microbiota, characterized by reduced short-chain fatty acid (SCFA)-producing taxa and an overrepresentation of pro-inflammatory species. These compositional changes affect metabolites such as SCFAs, bile acids, and microbial cell wall components, which interact with host receptors to promote peripheral and central sensitization. Microbiota-derived metabolites modulate peripheral sensitization by altering nociceptive neuron excitability and stimulating immune cells to release pro-inflammatory cytokines that increase blood-brain barrier permeability, activate microglia, and amplify neuroinflammation. Activated microglia further disrupt the balance between excitatory and inhibitory neurotransmission by enhancing glutamatergic activity and weakening GABAergic signaling, thereby contributing to the induction and maintenance of central sensitization. While observational studies establish associations between dysbiosis and chronic pain, animal models and early human fecal microbiota transplantation studies suggest a potential causal role of dysbiosis in pain, although human evidence remains preliminary and influenced by diet, lifestyle, and comorbidities. Overall, microbiota appears to regulate pain via peripheral and central mechanisms, and targeting it through specific interventions, such as dietary modulation to enhance SCFA production, alongside broader lifestyle measures like sleep, physical activity, stress management, and oral hygiene, may represent a new therapeutic strategy for the management of chronic pain.},

Gingerol-Enriched Ginger Extract Effects on Anxiety-like Behavior in a Neuropathic Pain Model via Colonic Microbiome-Neuroimmune Modulation.
Molecules (Basel, Switzerland), 31(1):.
Growing evidence has revealed that gut dysbiosis is associated with the development of anxio-depressive disorders through mechanisms that involve neuroimmune signaling, neurotransmitter changes, and neuroplasticity in the brain. This study investigated the effects of gingerol-enriched ginger (GEG) on specifically anxiety-related neuroinflammation-, neuroimmunity-, neuroplasticity-, neurotransmission-, and neurotoxicity-associated genes in different brain regions, as well as on alterations linked to colonic microflora-driven dysbiosis, in the spinal nerve ligation (SNL) rat model of neuropathic pain (NP). Twenty-seven male rats were assigned to 3 groups: sham, SNL, and SNL-treated with GEG at 200 mg/kg body weight (SNL+200GEG) via oral gavage for 5 weeks. Anxiety-like behavior was assessed on the elevated plus maze (EPM). mRNA expression was assessed by qRT-PCR using respective primers. Correlation between behavioral parameters and colonic microbiome composition was analyzed using the Spearman rank correlation. The SNL+200GEG group demonstrated decreased anxiety-like behavior in the SNL model. Compared to the SNL group, the SNL+200GEG group had increased mRNA expression of NRF2 (amygdala: left), LXRα (amygdala: both sides), and CX3CR1 (amygdala: both sides, hippocampus: right). GEG modulated neuroplasticity as shown by increased gene expression of PGK1 (amygdala: right, hippocampus: both sides), MEK1 (frontal cortex: both sides), LDHA (frontal cortex: both sides), GPM6A (frontal cortex: both sides, amygdala: right, hippocampus: right, and hypothalamus), and GLUT1 (amygdala: right) as well by decreased gene expression of HIF1α (in all brain regions except for the hypothalamus). GEG modulated neurotransmission via clearance of excessive glutamate release as suggested by increased gene expression of SLC1A3 (frontal cortex: both sides, hippocampus: right) and via augmenting mGluR5 signaling as shown by increased gene expression of GRM5 (hippocampus: both sides, hypothalamus) as well as downregulation of KMO, HAAO, GRIN2B, and GRIN2C influencing downstream serotonergic neurotransmission and NMDA receptor-mediated glutamatergic pathways in different brain regions. GEG further alleviated neurotoxicity through downregulated gene expression of SIRT1, KMO, IDO1, and HAAO in different brain regions. Moreover, the increased relative abundance of Bilophila spp., accompanied by decreased time spent in the EPM open arms, suggests that increased Bilophila abundance increases anxiety-like behavior. GEG supplementation mitigated anxiety-like behavior in male rats with NP, at least in part, by reducing SNL-induced inflammatory sequelae-related mRNA gene expression in different brain regions. In addition, there is a positive correlation between the abundance of Bilophila wadsworthia and the degree of anxiety-like behavior.

Molecules (Basel, Switzerland), 31(1):.
This comprehensive review presents the results of an in-depth analytical literature search on the biological activity of humic substances and their possible pharmacological mechanisms of action. The unique chemical structure of humic substances has determined their widespread use in many economic sectors, including medicine. Thanks to modern advances in pharmaceuticals, pharmacology, and toxicology, it has been possible to demonstrate the multifaceted biological activity of humic substances and, consequently, the possibility of using them to treat and prevent many infectious and non-infectious pathologies, including diseases considered incurable. The article presents data on their immunotropic, antibacterial, antiviral (including HIV), antitumor, antioxidant and antiradical, cardiotropic, hepatoprotective, regenerative, detoxifying, and adaptogenic effects; their influence on the intestinal microbiome; studies of the toxic properties of humic substances and the safety of their use in medicine; and the current trend of using humic substances as unique matrices for creating next-generation bionanomaterials. An analysis of data on the intracellular mechanisms that play a key role in the implementation of the effects of humic substances is conducted. Thus, the natural genesis of humic substances, their multifaceted biological activity, and the absence of toxic and allergenic properties explain the growing interest of scientists from all over the world in their study.

From Diet to Oral and Periodontal Health: Exploring the Crucial Role of Nutrition-A Narrative Review.
Nutrients, 18(1):.
Background: The growing body of evidence linking dietary factors to oral and periodontal health is characterized by substantial heterogeneity in study design, dietary assessment methods, and reported outcomes, warranting a comprehensive narrative synthesis. Diet is a key determinant of oral and periodontal health, influencing inflammation, oxidative stress, salivary composition, and the oral microbiome. Objectives: This narrative review aims to synthesize current clinical, epidemiological, and mechanistic evidence on how dietary patterns and specific nutrients affect oral and periodontal health, focusing on inflammatory pathways, microbiome modulation, nutrient-dependent tissue mechanisms, and clinical outcomes. Methods: A structured narrative search was conducted in PubMed, Scopus, Web of Science, and Google Scholar (2000-2025). Studies examining diet, nutrients, the oral microbiome, caries, gingival inflammation, or periodontal disease were screened through a multistep process, resulting in 98 included articles. Results: High-sugar and ultra-processed diets trigger inflammation and oral dysbiosis, increasing caries and periodontal susceptibility. In contrast, nutrient-rich and anti-inflammatory diets improve immune regulation, support microbial balance, and are associated with better periodontal parameters. Conclusions: Dietary habits significantly shape oral and periodontal outcomes through interconnected metabolic, microbial, and immunological pathways. Integrating targeted nutritional counseling into dental care may strengthen prevention strategies and improve long-term oral health.

Potato Protein-Based Vegan Burgers: Discovering the Health-Promoting Benefits and Impact on the Intestinal Microbiome.
Nutrients, 18(1):.
INTRODUCTION: The increasing global interest in plant-based diets has led to the development of innovative meat analogs that not only mimic the sensory properties of traditional products but may also offer potential health benefits. In this study, we investigated the nutritional characteristics and biological activity of potato protein-based vegan burgers (PBBs) enriched with plant-derived iron and fiber sources.
METHODS: The burgers were subjected to in vitro gastrointestinal digestion, followed by evaluation of their cytotoxic potential against human intestinal cancer cell lines (Caco-2 and HT-29) and normal colon epithelial cells (CCD 841 CoN). Additionally, their influence on the intestinal microbiota composition and enzymatic activity of β-glucosidase and β-glucuronidase was assessed.
RESULTS: PBBs demonstrated favorable nutritional profiles, high protein and fiber contents, and a balanced fatty acid ratio (n-6/n-3). After digestion, bioaccessible fractions showed selective cytotoxicity toward cancer cells, while maintaining safety for normal intestinal cells. Furthermore, PBBs modulated the gut microbiota by promoting the growth of beneficial genera (Lactobacillus, Bifidobacterium) and reducing potentially harmful Enterobacteriaceae, accompanied by decreased β-glucuronidase activity.
CONCLUSIONS: These findings suggest that potato protein-based burgers could represent a functional plant-based alternative to conventional meat products, contributing to intestinal health and potentially reducing colorectal cancer risk.

A Narrative Review: A1 and A2 Milk Beta Caseins Effect on Gut Microbiota.
Nutrients, 18(1):.
Background/Objectives: The composition and function of gut microbiome is significantly influenced by dietary factors. Growing evidence suggests that A1-type and A2-type beta casein (β-CN) may exert distinct effects on the gut environment, with implications for digestive discomfort and broader health outcomes. This review summarizes current evidence on how milk-derived A1 and A2 β-CN affect the gut microbiota. Methods: We conducted a literature search using PubMed, Web of Science, and Scopus to identify studies examining effects of milk β-CN on gut microbiota. Results: A total of eight studies were included. Results show inconsistencies within the limited number of studies. However, compared to A2, A1 β-CN was more frequently associated with dysbiosis and an increased abundance of potentially pathogenic species. Conversely, A2 β-CN promoted microbial diversity, which is linked to improved gut integrity and metabolic health. Conclusions: These findings suggest that β-CN variants distinctly influence the gut microbiota composition, and results were more significant in immunosuppressed subjects or those with other underlying health conditions, indicating that dairy products rich in A2 β-CN may offer advantages in personalized dietary management. However, well-designed human studies are essential to translate findings from rodent models to clinically relevant outcomes and future research should focus on mechanistic exploration and population-specific responses.

Subcellular Localization Dictates Therapeutic Function: Spatially Targeted Delivery of Amuc_1100 by Engineered Lacticaseibacillus paracasei L9 Enhances Intestinal Barrier in Colitis.
Nutrients, 18(1):.
Background/Objectives: Impaired intestinal barrier function is a hallmark of inflammatory bowel disease (IBD). Akkermansia muciniphila and its outer membrane protein Amuc_1100 can enhance this barrier, but the clinical application of Amuc_1100 is limited by the fastidious growth of its native host. This study aimed to overcome this by utilizing the robust probiotic Lacticaseibacillus paracasei L9 for targeted Amuc_1100 delivery. Methods: We engineered Lc. paracasei L9 to express Amuc_1100 via intracellular (pA-L9), secretory (pUA-L9), and surface-display (pUPA-L9) strategies. Their efficacy was assessed in Lipopolysaccharide (LPS)-induced macrophages and a dextran sulfate sodium (DSS)-induced colitis mouse model, evaluating inflammation, barrier integrity, and mucosal repair. Results: The secretory (pUA-L9) and surface-display (pUPA-L9) strains most effectively suppressed pro-inflammatory cytokines (IL-6, IL-1β, and TNF-α) in macrophages. In mice, both strains alleviated colitis and outperformed native A. muciniphila in improving disease activity. Crucially, they exhibited distinct, specialized functions: pUA-L9 acted as a systemic immunomodulator, reducing pro-inflammatory cytokines (IL-6, IL-1β, and TNF-α), elevating anti-inflammatory mediators (IL-4 and IL-10), and promoting goblet cell differentiation; notably, the inhibitory effect of pUA-L9 on IL-6 expression was approximately 2-fold greater than that of pUPA-L9. In contrast, pUPA-L9 excelled in local barrier repair, uniquely restoring mucus layer integrity (Muc1, Muc2, and Tff3) and reinforcing tight junctions (ZO-1, Occludin, Claudin1, Claudin3, and Claudin4). In particular, pUPA-L9 increased Muc2 expression by approximately 3.6-fold compared with pUA-L9. Conclusions: We demonstrate that the subcellular localization of Amuc_1100 within an engineered probiotic dictates its therapeutic mode of action. The complementary effects of secretory and surface-displayed Amuc_1100 offer a novel, spatially targeted strategy for precision microbiome therapy in IBD.

A Pilot Randomized Controlled Trial and Multi-Omics Analysis of Electrolysed Alkaline Water: Impacts on Gut Microbiota and Metabolic Signatures in Hyperuricemia.
Nutrients, 18(1):.
Background/Objectives: Hyperuricemia (HUA) is the second most common metabolic disease in China (24.5% in males, 3.6% in females), which can induce multiple complications such as gout and diabetes. Existing urate-lowering drugs have significant hepatorenal toxicity, necessitating safe lifestyle interventions. Electrolyzed alkaline water (EAW) as daily drinking water has shown preliminary effectiveness, but it lacks randomized controlled evidence and mechanistic studies at the microbiome-metabolome interface. Methods: We conducted a 12-week randomized controlled trial in 40 adults aged 18-65 years with elevated serum uric acid (SUA). Participants consumed either 1.5 L/day of EAW (pH 8.5-9.5) or purified water (pH 7.0). Clinical indicators, quality of life (SF-36), gut microbiota, and gut metabolomics were comprehensively assessed to evaluate intervention efficacy and explore potential mechanisms. Results: After 12 weeks, the EAW group exhibited a larger reduction in serum uric acid than the control group, along with improvements in selected physical health-related quality-of-life measures. Modest differences in gut microbial composition were observed between groups. Metabolomic analyses identified group-level differences in metabolites enriched in pathways related to purine metabolism and other urate-associated metabolic processes. Conclusions: This pilot randomized controlled trial suggests that consumption of EAW is associated with a modest reduction in serum uric acid. Exploratory multi-omics analyses indicate concurrent changes in gut microbiota and metabolic profiles. These findings support further investigation of electrolyzed alkaline water as a potential adjunctive, non-pharmacological option for hyperuricemia in larger and longer-term studies. Ethics: This trial was registered with the Chinese Clinical Trial Registry under the identifier ChiCTR2500100190. Ethical approval for the present study was granted by the Nankai University Institutional Review Board (NKUIRB2025001, 23 January 2025).

abstract = {Background/Objectives: Hyperuricemia (HUA) is the second most common metabolic disease in China (24.5% in males, 3.6% in females), which can induce multiple complications such as gout and diabetes. Existing urate-lowering drugs have significant hepatorenal toxicity, necessitating safe lifestyle interventions. Electrolyzed alkaline water (EAW) as daily drinking water has shown preliminary effectiveness, but it lacks randomized controlled evidence and mechanistic studies at the microbiome-metabolome interface. Methods: We conducted a 12-week randomized controlled trial in 40 adults aged 18-65 years with elevated serum uric acid (SUA).

The Immune Mind: Linking Dietary Patterns, Microbiota, and Psychological Health.
Nutrients, 18(1):.
Background/Objectives: Nutritional patterns influence the gut-brain axis and immune signaling with potential consequences for depression and anxiety. We conducted a review focused on clinically meaningful psychiatric outcomes (symptom severity/diagnosis) to synthesize recent evidence (2020-2025) on Mediterranean-style dietary interventions; ultra-processed food (UPF) exposure; and psychobiotic/prebiotic strategies, integrating mechanistic insights relevant to practice. Methods: Searches in PubMed/MEDLINE, Scopus, and Web of Science (January 2020-October 2025) combined terms for diet, Mediterranean diet (MD), UPF, microbiota, probiotics, psychobiotics, depression, and anxiety. Eligible designs were randomized/controlled trials (RCTs), prospective cohorts, and systematic reviews/meta-analyses reporting clinical psychiatric outcomes in adults. We prioritized high-quality quantitative syntheses and recent RCTs; data were extracted into a prespecified matrix and synthesized narratively. Results: Recent systematic reviews/meta-analyses support that MD interventions reduce depressive symptoms in adults with major or subthreshold depression, although large, long-term, multicenter RCTs remain a gap. Exposure to UPF is consistently associated with higher risk of common mental disorders and depressive outcomes in large prospective cohorts. Psychobiotics (specific probiotic strains and prebiotics) show small-to-moderate benefits on depressive symptoms across clinical and nonclinical samples, with heterogeneity in strains, dosing, and duration. Mechanistic reviews implicate microbiota-derived metabolites (short-chain fatty acids) and immune-inflammatory signaling (including tryptophan-kynurenine pathways) as plausible mediators. Conclusions: Clinically, emphasizing Mediterranean-style dietary patterns, reducing UPF intake, and considering targeted psychobiotics may complement standard psychiatric care for depression. Future work should prioritize adequately powered, longer RCTs with standardized dietary protocols and microbiome-informed stratification to clarify responders and mechanisms.

ESP Quick Facts
ESP Origins
In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.
ESP Support
In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.
ESP Rationale
Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.
ESP Goal
In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.
ESP Usage
Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.
ESP Content
When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.
ESP Help
Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.
ESP Plans
With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.
