abstract = {With the recent approval of maternal RSV vaccines and late-phase trials underway for a GBS vaccine, Europe is entering a new era of maternal immunisation. Yet scientific progress is outpacing pregnancy-specific evidence and preparedness for equitable implementation. Pregnant women are often excluded from early vaccine trials, while national recommendations, surveillance and delivery vary across Europe, even after regulatory authorisation. Without coordinated planning, new maternal vaccines risk reproducing the delays and inequities seen with influenza, pertussis and COVID-19 vaccination. In this Review, we examine scientific advances in the next generation of maternal vaccines, including mRNA, protein conjugate, nanoparticle and combination approaches, and candidates against emerging and other priority pathogens. We discuss barriers to including pregnant women in trials, assess regulatory and pharmacovigilance readiness, and identify health-system and vaccine-confidence risks to equitable rollout. We offer strategic recommendations for Europe's maternal immunisation roadmap, from research investment to policy integration, provider education, and equity-centred planning. Realising this potential will require integrated action across research, regulation, implementation, and communication. This is the final paper in the Series on the future of maternal vaccination in Europe and synthesises its findings into a framework for Europe and beyond.},

In addition to the iron-saturated transferrin, ligands of transferrin receptor also include its homologues lactoferrin and melanotransferrin, as well as heavy-chain ferritin and heme complex with human serum albumin. Activation of ferroptosis, including by increasing the labile pool of iron in tumor cells, is considered a promising strategy for combating cancer. However, a number of pathogenic human viruses, including influenza virus, SARS-CoV-2 coronavirus, and rabies virus, use binding with TfR1 to infect cells and affect ferroptosis. The review summarizes information on natural and synthetic TfR1 regulators, including the mechanisms of their influence on the development of ferroptosis and the prospects for their use as antiviral agents.},

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continuously evolves through genetic mutations to enhance its adaptability to hosts, thereby posing significant challenges to global public health. Consequently, the discovery of novel antiviral agents remains imperative. Salvia miltiorrhiza Bunge (Danshen), a widely utilized traditional Chinese medicine (TCM), has demonstrated preclinical antiviral activity in silico, in vitro and in animal models. However, existing evidence on Danshen's bioactive constituents against SARS-CoV-2 is predominantly preclinical. Further clinical investigations are required to validate the antiviral efficacy of isolated monomers. Consequently, a systematic understanding of these aspects remains incomplete. This review summarizes the preclinical antiviral activity and underlying mechanisms of bioactive constituents derived from Danshen against SARS-CoV-2, together with their metabolism and safety profiles. By synthesizing these findings, we aim to provide insights into the potential of these constituents for further development, thereby guiding the discovery of natural antiviral lead compounds against SARS-CoV-2 and future emerging viral infections.

A review of contemporary records of five prison systems during the 1918-1919 influenza pandemic showed that most prison populations did remarkably well under lockdown, with few resulting respiratory deaths. Exceptional prisons with high respiratory mortality included the Andaman Islands prison colony (17.3/1000) and the US Army Disciplinary Barracks (42/1000) at Fort Leavenworth, Kansas. Factors that likely resulted in high respiratory mortality included the absence of earlier waves of influenza-like illness and increased prisoner turnover introducing additional respiratory bacteria strains. Prison staff often had influenza rates that were very different to those of the prisoners they were guarding. Although free populations resented social restrictions during the COVID-19 pandemic, controlling population movements can serve to limit respiratory pathogen spread while waiting for alternative public health measures such as immunisations to arrive.},

abstract = {BACKGROUND: High-flow nasal cannula (HFNC) is widely used as an early respiratory support strategy for adults with acute hypoxemic respiratory failure (AHRF). Although HFNC may reduce the risk of endotracheal intubation, it remains uncertain whether the available evidence is sufficiently mature and whether this potential benefit translates into improved survival. We performed a systematic review and meta-analysis with trial sequential analysis (TSA) and GRADE assessment to assess HFNC versus standard oxygen therapy (SOT) in adult AHRF.

METHODS: PubMed, Embase, the Cochrane Library, and Web of Science were searched from inception to March 31, 2026. Randomized controlled trials (RCTs) of HFNC versus SOT in adults with AHRF were included. The primary and secondary outcomes were endotracheal intubation and all-cause mortality, respectively. For each dichotomous outcome, the risk ratio (RR) with a 95% confidence interval (CI) was pooled using a random-effects model. Prespecified subgroup analyses were performed. TSA was performed for intubation, and evidence certainty was assessed using GRADE.

RESULTS: Ten independent RCTs reported across 11 publications were included. Compared with SOT, HFNC was associated with a lower risk of endotracheal intubation (RR, 0.85; 95% CI, 0.77-0.93; P < 0.01; I² = 40%), but did not reduce all-cause mortality (RR, 1.01; 95% CI, 0.88-1.16; P = 0.85; I² = 0%). Subgroup analyses suggested a lower intubation risk with HFNC among non-immunocompromised patients, patients with COVID-19, and those with baseline PaO₂/FiO₂ ≤ 200 mmHg, although no statistically significant subgroup interactions were observed. In the primary TSA, the accrued sample size represented only 36.8% of the diversity-adjusted required information size. The cumulative Z-curve crossed the conventional significance boundary, but not the trial sequential monitoring boundary. TSA sensitivity analyses yielded consistent findings, indicating that current evidence remains inconclusive. GRADE certainty was low for endotracheal intubation and moderate for all-cause mortality.

CONCLUSIONS: HFNC may reduce the risk of endotracheal intubation compared with SOT in adults with AHRF, but a survival benefit has not been demonstrated.},

The COVID-19 pandemic further demonstrated the need for assessments to be offered online to allow for remote data collection. However, the design and implementation of computerized tests in an online environment come with various challenges. This article probes the issues, needs and challenges for the development of online assessment of reading and maths, and related cognitive abilities. The paper aims to inform researchers about logistical and technical considerations of developing a customized platform for online child data collection, including (a) technical considerations, (b) interface design, (c) data management, and (d) planning for validation against paper-and-pencil measures. These issues are illustrated with experiences gleaned from the development of an online assessment platform (ACE Kids platform), designed to deliver over 40 tests and questionnaires related to Chinese and English literacy as well as mathematics abilities in K3 - P6 children. The paper also highlights the unique challenges surrounding building online, self-directed biliteracy assessment involving a large assessment battery. Furthermore, we discuss features that improve the ease of use, instructional clarity, and retention of attention. We discussed the use of questionnaires to sample child usage experience during early stages of assessment development to optimize design. Finally, we give consolidated advice for the planning, development and data collection stages for such a customized assessment platform.},

METHODS: This is a scoping review. Document selection occurred independently in stages previously defined in a research protocol. The review included primary studies, reviews, and grey literature that underwent peer review and produced evidence from quantitative information on nutrition status held on SISVAN Web, for all populations and locations. Data extraction was standardized, and publications were analyzed according to a glossary developed to standardize methodological aspects.

RESULTS: A total of 1,294 records were identified, and 161 were analyzed after applying the eligibility criteria. There was a significant increase in publications, especially from 2021 onwards, with emphasis on ecological time-series designs, which have adopted robust methods to analyze SISVAN data. Twenty-nine studies were identified that worked with individualized data, with cross-sectional or retrospective cohort analysis. The most studied life stage was childhood, particularly up to 5 years of age. In 40 studies, the data source was stratified, and most used data from the Bolsa Família Program. Pernambuco, Minas Gerais and Bahia were the states most studied. Some studies investigated the effect of the COVID-19 pandemic on SISVAN indicators or used georeferencing/spatial analysis methods.

CONCLUSION: This review presented the state of the art of scientific production using nutrition information from SISVAN and characterized methodological aspects, thus informing future research.},

abstract = {Respiratory viral infections represent a major global health burden, with impaired antiviral interferon responses contributing to disease progression in several respiratory conditions. This systematic review evaluated the efficacy, safety, and biological effects of locally delivered intranasal or inhaled interferon-β1a (IFN-β1a), a host-directed antiviral therapy, across prophylactic, therapeutic, and experimental models of respiratory viral infections. A systematic review was conducted according to PRISMA 2020 guidelines by searching PubMed, Embase, Scopus, Web of Science, Google Scholar, patent databases, and ClinicalTrials.gov up to July 2025. Peer-reviewed clinical and experimental studies, as well as relevant patent records, were identified. Patent and grey-literature sources were examined to provide a comprehensive overview of the development of locally delivered IFN-β1a and to identify relevant technological approaches that might not be captured in conventional bibliographic databases; however, these records were not considered evidence of clinical efficacy or safety. Eligible clinical and experimental evidence included randomized controlled trials (RCTs), in vitro, and in vivo studies. Owing to substantial clinical and methodological heterogeneity, findings were synthesised using a structured narrative and stratified approach rather than quantitative pooling. Risk of bias was assessed using RoB 2 for RCTs, ToxRTool for in vitro studies, and the SYRCLE tool for in vivo studies. Twenty-four studies met the inclusion criteria, including 12 RCTs, seven in vitro studies, one in vivo study, and four patent reports. Preclinical evidence consistently demonstrated antiviral and immunomodulatory activity, including reduced viral replication and induction of interferon-stimulated genes. Clinical studies demonstrated consistent antiviral activity and immune modulation (e.g., ISG upregulation, viral load reduction). However, clinically meaningful benefit varied across populations and was most consistent in asthma, COPD, and hospitalised COVID-19 patients, whereas other trials did not demonstrate significant improvements in their primary clinical outcomes. Early prophylactic studies in rhinovirus infection showed limited and inconsistent clinical preventive efficacy despite detectable antiviral activity. Pharmacokinetic studies supported effective airway delivery, while safety findings indicated generally favourable tolerability with predominantly mild, transient adverse events. Available evidence indicates that intranasal or inhaled IFN-β may enhance antiviral immunity and provide clinical benefit in selected respiratory viral conditions, particularly among individuals with impaired antiviral responses. However, evidence for prophylactic efficacy against community-acquired upper respiratory tract infections remains limited, and further studies are required to define optimal indications, dosing strategies, and target populations.},

A novel saturation-based approach, adapted from qualitative research, was used to determine when no new implicit or explicit conceptualisations of risk were evident. Ten initial papers were reviewed, followed by sets of three, stopping after saturation was reached at 24 papers. The word 'risk' appeared 722 times across included studies. Hundreds of distinct implicit and explicit conceptualisations were identified and grouped according to five interconnected dimensions: health outcomes, and their focus on biomedical, behavioural, interpersonal, and individual factors. Findings highlight the pervasive yet variable use of 'risk' in the sexual health literature, which may hinder clear communication between researchers, clinicians, and service users. Study findings support calls for the use of more precise language.},

Comparing these conditions may clarify whether post-acute symptoms reflect specific consequences of SARS-CoV-2 infection or broader post-viral mechanisms.

METHODS: We conducted a systematic review and meta-analysis of cohort studies comparing persistent symptoms or conditions in adults after SARS-CoV-2 infection with those following other acute respiratory viral infections. PubMed, Embase, and Scopus were searched. Random-effects models were used to estimate pooled risks.

RESULTS: Among 9371 records screened, 22 studies were included, and 14 contributed to the meta-analysis. Increased risks after SARS-CoV-2 infection were observed for pulmonary embolism, abnormal breathing, fatigue, hemorrhagic stroke, memory loss/brain fog, and palpitations; heart rate abnormalities showed borderline significance. For most other outcomes, pooled estimates did not indicate significantly higher risks than those after other acute respiratory viral infections.

CONCLUSION: Our findings support the concept of post-COVID-19 condition as one example within the broader spectrum of post-acute infection syndromes, underscoring the need to recognize these conditions after non-COVID respiratory viral infections and to further investigate shared and pathogen-specific mechanisms.},

abstract = {BACKGROUND: Public health waiting lists for elective or planned orthopaedic surgery are increasing to the point where demand far exceeds our ability to treat. This is largely due to ageing populations, rising obesity and the continued impact of delays caused by the COVID-19 pandemic. While waiting, patients suffer debilitating physical pain, functional limitation, social isolation, and associated mental health impacts while some are unable to work. This qualitative scoping review explored and mapped the experiences of patients of waiting for elective or planned orthopaedic surgery.

METHODS: This review was conducted according to the Joanna Briggs Institute Scoping Review methodology and reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. A comprehensive database search was conducted to identify English-language articles from 2009 until June 2025. Data extraction was informed by the Standards for Reporting Qualitative Research. Results were thematically analysed and presented using the Quality Health Outcomes Model.

RESULTS: The initial search identified 4713 articles, of which 21 manuscripts met inclusion criteria. The 21 articles comprised 17 primary qualitative research studies and four review articles published within the designated time period (2009-2025). Two key themes were identified: (i) patients waiting for elective orthopaedic surgery need psychosocial support and (ii) system-level, multifactorial communication issues with the waiting list leave patients feeling lost between primary and specialist care. These themes suggest that the challenges faced due to lengthy elective surgery waiting lists are not simply a capacity issue, but also a challenge of coordinated, patient- centred care.

CONCLUSION: Waiting for surgery is consistently described by patients as a source of anxiety and distress. With waiting list times for elective surgery increasing, the experience can be improved in part with adequate communication from healthcare providers. A re-focus on what matters most to the patient and their family is required in order to deliver adequate patient-centred care while patients wait for surgery.},

abstract = {BACKGROUND Extracorporeal membrane oxygenation (ECMO) is a rescue therapy for severe COVID-19-related acute respiratory distress syndrome (ARDS). International datasets do not consistently report Central and Eastern Europe (CEE) separately. We aimed to assess mortality, clinical characteristics, and complications of ECMO-treated COVID-19 patients across the CEE region. MATERIAL AND METHODS We conducted a systematic review with single-arm meta-analyses of observational studies. PubMed, Scopus, Embase, and Web of Science were searched from January 2020 to August 2025 for studies reporting ECMO outcomes in adult (≥18 years) COVID-19 patients from CEE countries, with at least 10 ECMO-treated patients. Conference abstracts and overlapping cohorts were excluded. The study protocol was registered with PROSPERO (CRD420251077593). RESULTS Twelve studies included 802 patients from 6 countries. Pooled in-hospital mortality was 65% (95% CI 0.57-0.72; I[2]=70.6%; 10 studies; n=691), and ICU mortality was 61% (95% CI 0.47-0.74; I[2]=85.8%; 7 studies, n=526). Country-level in-hospital mortality estimates were 54% for the Czech Republic and 76% for Poland but were descriptive because of the small number of studies and wide CIs. Mean pre-ECMO mechanical ventilation duration was 4.8 days (95% CI 3.7-5.8; I[2]=4.4%), ECMO duration was 17.8 days (95% CI 12.8-22.9; I[2]=79.8%), and ICU length of stay was 23.6 days (95% CI 7.5-39.7; I[2]=92.6%). Serious bleeding occurred in 40% (95% CI 22-61%; I[2]=85.7%). Certainty was very low for all pooled outcomes. CONCLUSIONS These CEE-specific estimates provide regional benchmarks, but substantial heterogeneity and very low certainty limit international comparisons and country-level interpretation. Standardized regional registries, prospective multicenter data, harmonized complication reporting, and long-term outcome assessment are needed.},

abstract = {BACKGROUND: Invasive fungal diseases (IFDs) have traditionally been regarded as complications of classical immunosuppression. However, IFDs are increasingly recognized in adults who are apparently immunocompetent or non-neutropenic, particularly in the setting of severe viral pneumonia, critical illness, diabetes, structural lung disease, surgery, trauma or burns, injection or inhalational drug use, invasive devices, broad-spectrum antibiotics, and previously unrecognized immune dysregulation.

OBJECTIVE: This narrative review summarizes emerging patterns and clinical challenges of IFD in apparently immunocompetent adults, integrating invasive molds, endemic dimorphic fungi, and invasive yeasts.

KEY OBSERVATIONS: The current landscape includes influenza- and COVID-19-associated pulmonary aspergillosis, COVID-19-associated mucormycosis, acute invasive mold disease in critically ill patients, tissue-injury- and trauma-associated mold infections, severe endemic mycoses after relevant environmental exposure, and an expanding spectrum of invasive yeasts. The label "immunocompetent" often conceals situational immune dysfunction or an undiagnosed inborn or acquired immune defect. Cohort data are available for several non-classical host groups, whereas evidence for truly healthy adults remains dominated by small series and case reports.

CONCLUSION: In adults without classical immunosuppression, IFD should be suspected when clinical deterioration occurs in the setting of acute illness, disruption of skin or mucosal barriers, indwelling catheters, healthcare exposure, unusual clinical syndromes, relevant geographic exposure, or unrecognized immune defects.},

abstract = {BACKGROUND: Programmable messenger RNA (mRNA) platforms can encode tumor antigens or immunomodulators, enabling coordinated antigen delivery and immune modulation. Yet the literature spans cancer vaccination, delivery engineering, immune biology, and adjacent infectious-disease research, making its structure and evidentiary boundaries difficult to discern. We mapped this cross-domain corpus to clarify its development, organization, and relevance to cancer-associated immune escape.

METHODS: We searched the Web of Science Core Collection (WoSCC) and Scopus on July 29, 2026, for English-language Articles and Reviews published since 2006. The strategy combined programmable or therapeutic mRNA, cancer, and immune-escape-related concepts. R-based analyses summarized the number of publications (NP), total citations (TC), and collaboration patterns; BERTopic modeled titles and abstracts after entity-aware preprocessing. Independent two-author review supported the five topic labels and characterized the outliers, and robustness was assessed across alternative clustering configurations.

RESULTS: The dataset comprised 756 publications (NP = 756). Annual output increased more than fourfold in 2021 and reached NP = 182 in 2025. China (NP = 291; 38.49%) and the United States (NP = 146; 19.31%) accounted for nearly 58% of corresponding-author publications. Sichuan University and Frontiers in Immunology ranked first in institutional and journal output, respectively. Nature had the highest retained source-record citation total (TC = 2,326). BERTopic assigned 745 publications to five topics, while 11 of 756 records remained outliers (1.46%). The topics represented mRNA delivery and immunomodulatory cancer-vaccine research (52.1%), SARS-CoV-2 vaccination in oncology and immunotherapy settings (23.6%), therapeutic mRNA cancer-vaccine platforms (13.3%), tumor-antigen discovery and immune-subtype stratification (8.6%), and mRNA-vaccine immunogenicity during autoimmune immunosuppression (2.4%).

CONCLUSIONS: Publication activity in the retrieved cross-domain corpus expanded rapidly after 2020. The corpus included both direct cancer-mRNA research and adjacent platform or immune-response literature. By distinguishing these components and identifying thematic connections among delivery, antigen selection, immune context, and collaboration, the analysis provides an evidence-navigation framework for prioritizing systematic reviews, mechanistic studies, and clinical evaluation. The map does not itself establish therapeutic efficacy.},

abstract = {Inhaled nitric oxide (iNO) is a selective pulmonary vasodilator that improves ventilation-perfusion matching with minimal effect on systemic blood pressure. Although the FDA approval is restricted to neonatal hypoxic respiratory failure associated with pulmonary hypertension, many clinicians now use iNO in adults with conditions where elevated pulmonary vascular resistance, right ventricular dysfunction threaten stability and hypoxic respiratory failure. This review examines both the mechanistic rationale and the available evidence for such off-label use. Examples range from acute RV failure in the ICU to perioperative support in cardiac surgery, heart and lung transplantation, and severe hypoxemic respiratory failure, including COVID-19-associated acute respiratory distress syndrome (ARDS). In these settings, iNO offers rapid afterload reduction and short-term improvement in oxygenation, but randomized trials are lacking and limited studies to date have failed to consistently show outcome benefits. Adverse effects such as methemoglobinemia, nitrogen dioxide toxicity, rebound pulmonary hypertension, and a potential increase in acute kidney injury risk in certain non-cardiac surgical populations. Additionally, cost considerations and other practical limitations must be weighed carefully. Overall, current evidence supports the use of iNO as an adjunctive therapy in carefully selected critically ill patients.},

Idiopathic pulmonary fibrosis (IPF) is the most common and severe form of F-ILD. Regulator-approved anti-fibrotic drugs, such as pirfenidone and nintedanib, delay rather than reverse disease progression, so the threat of eventual respiratory failure remains. While lung transplantation is an option that can prolong survival for end-stage IPF, its clinical application is greatly restricted by donor shortages, surgical risks, and postoperative complications. Stem cell therapies, and particularly treatments based on mesenchymal stromal/stem cells (MSCs) and their derivatives, have brought new hope for the management of F-ILD due to their immune regulatory, anti-inflammatory, and anti-fibrotic capabilities. A search was conducted to identify relevant articles in the PubMed/MEDLINE, Web of Science, Cochrane Library, China National Knowledge Internet and Wanfang Data from inception to 31st May 2026. This review summarizes the mechanistic overview of stem cell-based therapeutic strategies for F-ILD, safety profiles and therapeutic potentials of various stem cells for the treatment of IPF and other F-ILDs, with an emphasis on stem cell types and delivery routine. This article also discusses the challenges and limitations of stem cell-based therapies, highlighting the need for further clinical studies with standardized efficacy endpoints to validate their effectiveness.},

However, its successful implementation depends on population knowledge, attitudes, and practices (KAP). This study aimed to synthesize available evidence on KAP related to dengue vaccination in the region. A scoping review was conducted following JBI guidelines. Searches were performed in international and regional databases, including MEDLINE/PubMed, Scopus, Embase, Web of Science, SciELO, and the Virtual Health Library. Original studies were included without language or date restrictions. Study selection and data extraction were conducted independently and in duplicate. Sixteen studies were included. Most studies reported limited knowledge regarding vaccine availability, safety, and mechanisms of action. In contrast, attitudes were generally favorable, with high acceptance and willingness to pay, estimated at approximately USD 23 for a three-dose regimen. However, willingness to participate in clinical trials remained low due to safety and trust concerns. Evidence from a study conducted in Puerto Rico indicated that the COVID-19 pandemic was associated with increased intention to receive the dengue vaccine. Practices were less studied, and findings showed low completion of vaccination schedules, indicating a gap between attitudes and uptake. Despite generally favorable attitudes, important knowledge gaps and implementation challenges persist. Strengthening educational strategies and promoting qualified communication between healthcare professionals and the population - particularly during the introduction of new vaccines and in the context of adverse events - may support informed decision-making and improve dengue vaccine uptake.},

A systematic review of articles published up to April 2026 was conducted following the PRISMA guidelines, and observational studies evaluating neurophysiological, structural, and functional alterations in individuals with long COVID were analyzed. Forty-two studies with substantial variability in design and methods were included; thus, the findings were synthesized narratively. The evidence indicates heterogeneous yet recurrent alterations in the central nervous system of individuals with lonf COVID, including impaired cortical excitability, abnormal cerebral oscillatory activity across multiple frequency bands, changes in functional connectivity, and structural abnormalities in neural networks. Some studies also reported imbalances in excitatory-inhibitory neurotransmission and biomarkers suggestive of neuroinflammation or axonal injury. These neurophysiological and structural alterations were commonly associated with persistent fatigue, cognitive dysfunction, and brain fog. However, the available evidence is limited by important methodological issues, including substantial heterogeneity in study populations, assessment techniques, and reported outcomes; the observational design also limited the strength of the conclusions. Taken together, the current evidence suggests a persistent and multifactorial central nervous system dysfunction in long COVID. However, definitive conclusions remain limited, and well-designed prospective longitudinal studies using standardized methods are needed to clarify the mechanisms, duration, and clinical relevance of these alterations.},

abstract = {BACKGROUND: Persistent respiratory sequelae following acute viral infections, exemplified by but not limited to coronavirus disease 2019 (COVID-19), represent a major unmet clinical challenge. Conventional anti-inflammatory strategies frequently fail to resolve these chronic symptoms, suggesting that additional pathogenic mechanisms, particularly neuroinflammatory processes, remain unaddressed.

MAIN BODY: This review synthesizes current evidence establishing neuroimmune axis dysfunction as an important mechanistic contributor to post-viral pulmonary sequelae, including chronic cough, airway hyperresponsiveness, and fibrotic remodeling. We systematically examine how viral infection alters the nervous system, and how these neural changes initiate and perpetuate neuroimmune axis dysfunction, subsequently orchestrating aberrant peripheral immune activation while impairing lung repair processes. Moreover, we critically appraise the emerging pharmacological landscape targeting this neuroinflammatory axis, spanning neuropeptide receptor antagonists, neuromodulation, and other mechanism-based strategies aimed at restoring neuroimmune homeostasis.

CONCLUSION: This review identifies neuroimmune axis dysfunction as a potential driver of persistent pulmonary sequelae and underscores the need for therapeutic strategies tailored to disease stage and clinical phenotype to enhance clinical translation.},

Evidence shows that microplastics damage respiratory epithelium, generate reactive oxygen species, and trigger inflammation whilst dysregulating immune cells, worsening coronavirus and influenza virus infections, leading to more severe and prolonged lung damage. This review outlines recent progress in how microplastics influence susceptibility to and development of respiratory viral infections, offering a scientific basis for creating targeted environmental health strategies and enhancing research on viral resistance mechanisms.},

Scholars have turned to trauma-informed approaches to understand how nursing students can be better supported in their education and mitigate the effects of past, current, and future trauma exposure.

AIM: To examine the current published literature on how trauma-informed approaches to nursing education are described in the literature.

DESIGN: We conducted a scoping review following the Joanna Briggs Institute framework. We used the PRISMA-ScR guidelines for reporting of findings.

METHODS: We performed searches in June 2024 and then again in June 2025 in Medline via OVID, CINAHL via EBSCO, ERIC, PsycInfo, Education Research Complete, and Scopus. We included literature published in English in any year that focused on nursing students and/or nurse educators, included a definition of a trauma-informed approach (TIA) and involved any education context.

RESULTS: 35 sources were included, published between 2020 and 2025. Study types included 11 descriptions of implementing a TIA and 6 unstructured reviews supporting its implementation. 10 sources were primary research. Findings included descriptive categories of definitions of a TIA, sources of nursing students' exposure to trauma (in their education, personal lives, and specifically COVID-19), and the purpose of a TIA (success in education and the creation of a future workforce).

CONCLUSIONS: TIA to support student learning and develop the future nursing workforce are increasingly prevalent and recommended in the nursing education literature. Terminology and definitions of TIA varied but often shared commonalities, with some specifically addressing structural inequities. Differences between definitions that highlight structural inequities specifically need to be examined for how they differ from more common definitions. The student perspective on resilience and TIA effectiveness is needed. Conceptualizations of TIA must also address how they might reinforce power structures within educational institutions, thereby avoiding the reproduction of inequities.},

AIM AND SCOPE: Unlike earlier descriptive, platform-specific surveys, this review is organised around structure-property-performance relationships and applies a uniform critical lens to the primary literature.

METHODS: We examine optical (fluorescence, surface plasmon resonance, colorimetric, SERS), electrochemical, and field-effect transistor (FET) biosensors. We compare them head-to-head on sensitivity, reproducibility, scalability, and clinical readiness.

KEY FINDINGS: GBN platforms detect pathogens such as SARS-CoV-2, cancer biomarkers, metabolites, and environmental toxins with high sensitivity and selectivity. However, many reported ultra-low detection limits are extrapolated from buffer calibrations rather than measured, and they are rarely validated in blinded clinical cohorts. Some are also physically implausible given the number of target molecules in the assay volume.

CHALLENGES: Key barriers are cytotoxicity, non-specific binding, irreproducible synthesis, and regulatory validation. For FETs specifically, the main obstacles are Debye screening, baseline drift, and poor wafer-scale yield.

CONCLUSIONS: AI-assisted signal processing, wearable and implantable devices, and 3D-printed multi-analyte lab-on-a-chip systems are critical future directions. Addressing these challenges through interdisciplinary effort could make GBN biosensors a foundation for personalized, point-of-care healthcare.},

abstract = {Axillary lymphadenopathy following vaccination has long been recognized as a benign, self-limited immune response, but its increased frequency during the COVID 19 vaccination campaign created diagnostic uncertainty and contributed to delays in breast imaging and unnecessary follow-up. Early conservative guidance, issued in the context of limited evidence, led to postponed screening examinations and increased patient anxiety. Since then, robust prospective and longitudinal data have demonstrated an extremely low, near-zero risk of malignancy in asymptomatic patients with isolated ipsilateral axillary lymphadenopathy following recent COVID 19 vaccination and no suspicious breast imaging findings, even when lymphadenopathy persists for many months. In response to this evolving evidence base, the Canadian Association of Radiologists (CAR) and Breast Radiologists of Canada (BRC) have developed updated, evidence-based recommendations for the management of axillary lymphadenopathy following COVID 19 vaccination. These recommendations emphasize that breast imaging examinations should not be delayed because of vaccination, outline the importance of documenting vaccination history, and provide clear guidance for classifying and managing ipsilateral, contralateral, palpable, and persistent lymphadenopathy across breast imaging modalities. Special considerations for patients with a personal history of breast cancer or other malignancies are also addressed. Adoption of these recommendations is intended to promote consistent national practice, reduce unnecessary imaging and biopsy, support patient reassurance, and maintain the effectiveness of breast cancer screening programs.},

Framed by the "iceberg concept" of disease, most cases are mild or asymptomatic, yet severe outcomes (e.g., exacerbations of chronic conditions) contribute to rare mortality. Management focuses on symptom relief: decongestants and antihistamines alleviate nasal congestion and cough in adults, though cough suppressants are discouraged in children. Despite its self-limiting nature, the common cold underscores challenges in primary care due to viral diversity and a lack of targeted therapies. Annual influenza vaccination, while not preventing colds, mitigates flu-related complications, indirectly reducing overlapping URTI burdens. Public health strategies emphasizing prevention, symptom management, and judicious antibiotic use remain critical to curbing its widespread impact.},

Its global prevalence has risen sharply over recent decades, affecting more than one in eight people worldwide, with a growing burden in low- and middle-income countries. This paper explores obesity as a complex and growing public health challenge that extends beyond individual behavior. It highlights the social, economic, and environmental factors driving the epidemic, with a focus on the Indian context where undernutrition and overnutrition coexist. Recent research, population data, and policy reports were reviewed to analyze current trends, determinants, and the limitations of traditional measures such as the body mass index (BMI). Particular attention was given to South Asian populations, who are prone to obesity-related diseases at lower BMI thresholds. Global obesity rates have risen sharply, now affecting more than one in eight people, with a marked increase in low- and middle-income countries. In India, urbanization, sedentary lifestyles, and the easy availability of ultraprocessed foods have accelerated the problem across all age groups. The COVID-19 pandemic worsened the situation through reduced physical activity, stress, and food-system disruptions. Conventional BMI measures underestimate true metabolic risk in South Asians, underscoring the need for more nuanced diagnostic approaches. Obesity adds significantly to the burden of noncommunicable diseases and demands multisectoral action through healthier food policies, physical activity promotion, and early prevention. Integrating these strategies into health systems is vital to reduce its long-term impact.},

Despite an ongoing investigation attributing its etiology to adenovirus infection, the absence of adenovirus inclusions in liver biopsies and the remarkably low viral load raised doubts. Concurrently, reports of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in children coincided with the surge in acute hepatitis cases, prompting the need for a thorough examination of the potential connection between current or past SARS-CoV-2 infections and pediatric hepatitis epidemics. Epidemiological data suggests that acute hepatitis is a notable manifestation of the multiple-system inflammatory syndrome in children following the global SARS-CoV-2 pandemic. However, the precise role of the SARS-CoV-2 virus in liver injury etiology remains uncertain. To shed light on the potential association between SARS-CoV-2 and AHUO in children, we conducted a systematic review of epidemiological links, potential pathogenesis, and recent research findings, aiming to raise awareness and vigilance among clinicians. Convincing and definitive evidence will be essential in the future to confirm the direct impact of SARS-CoV-2 infection on children with AHUO.},

abstract = {Mucosal vaccines have risen to prominence in the corona virus disease 2019 (COVID-19) pandemic due to their ability to elicit both local antibody and tissue-resident T cell responses, affording a dual-layered defense against infection and transmission at respiratory entry sites. While intramuscular vaccines predominantly focus on systemic immunity, mucosal vaccines offer a more nuanced, site-specific approach. However, the field faces a dearth of mucosal vaccine options for respiratory diseases, starkly contrasting to the extensive array of well-characterized injectable vaccines. The unique features of mucosal surfaces necessitate specialized adjuvants and delivery systems, adding complexity to adapting injectable vaccine technologies for mucosal applications. Here, we review the recent insights into the specificities of respiratory mucosal immunology that provide a foundation for future innovations besides the emerging vaccine platforms, newly discovered adjuvants, and vaccine delivery systems, which may open promising avenues for developing mucosal vaccines targeting respiratory pathogens.},

Currently, researchers worldwide are extensively exploring the application of organoids in virology and have achieved remarkable progress. These innovations have enabled the successful cultivation of various viruses in vitro, the modeling of viral infection processes, and the clarification of cell tropism and host factor interactions. They have also advanced systematic explanations of related pathogenic mechanisms, providing an important avenue for antiviral drug screening and vaccine design. This paper elaborates on the biological characteristics of organoids, summarizes the methodologies for establishing virus-infected organoid models, and reviews advances in research on viruses such as severe acute respiratory syndrome coronavirus 2, influenza viruses, hepatitis viruses, Zika virus, and human noroviruses. This review will clarify how organoids have profoundly changed our understanding of the pathogenic mechanism of viruses and accelerated the clinical translation of antiviral strategies.},

Seizure development following viral infection involves diverse CNS mechanisms, with emerging evidence that peripheral factors, including gut microbiome composition and immune-inflammatory responses, also contribute. The gut microbiome is a multifaceted ecosystem with important roles in CNS health, and advances in sequencing have enabled investigation of host and microbial genomic changes associated with seizure development. While both animal and human studies link gut dysbiosis to epilepsy, including infection-induced epilepsy, the specific effects of viral-induced seizures on the gut microbiome remain unclear. Moreover, the influence of virus-triggered epileptogenesis is not well understood. This review summarizes current knowledge on viral infections linked to seizures and highlights the limited but growing evidence for gut microbial changes in this context. We focus on Zika virus (ZIKV), West Nile virus (WNV), and herpes simplex virus-1 (HSV-1), all implicated in human epileptogenesis, though direct microbiome-seizure connections are still limited. We also discuss severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), which causes neurological symptoms without consistently inducing seizures in rodent models despite neurological involvement, and Theiler's murine encephalomyelitis virus (TMEV), a murine virus widely used as a model of infection-induced seizures because it induces strain-dependent seizures in mice. Current evidence suggests associations among viral infections, gut microbiome alterations, and seizure occurrence; however, further causative studies are needed to define their roles and elucidate underlying mechanisms.},

This review synthesises evidence from academic studies, surveillance reports, and European initiatives to describe the diverse modalities of CBT, as well as their contribution to earlier diagnosis, improved case-finding among first-time testers, and more timely linkage to care. Across the region, CBT showed higher acceptability and positivity yields than facility-based testing, reaching populations disproportionately affected by HIV, such as men who have sex with men, people who inject drugs, migrants, and sex workers, and supports differentiated, person-centred service delivery aligned with World Health Organization and European Centre for Disease Prevention and Control guidance. Despite clear progress, major implementation gaps persist, driven by restrictive regulatory frameworks, uneven adoption of innovations such as lay provider testing and HIV self-testing, limited integration of community-generated data into national surveillance systems, and structural inequities including stigma, criminalisation, and lack of universal healthcare entitlements. This review also notes the resilience and adaptability of community-based models during recent crises, including COVID-19 and the war in Ukraine. Overall, the evidence demonstrates that CBT is a fundamental component of HIV prevention and diagnosis in ECA. Fully realising its potential requires updated policies that enable task-sharing, integration of multi-disease testing, strong referral pathways, sustainable financing, and formal incorporation of community-generated data into national monitoring frameworks. Strengthening these components is essential to accelerate progress toward the 2030 goal of ending AIDS as a public health threat.},

These responses have undoubtedly impacted the evolutionary dynamics of the virus in ways distinct from a scenario lacking a widespread response. Two important pharmaceutical interventions, vaccination and the utilization of medications, particularly molnupiravir, known to have mutagenic properties, were the focus of this article. The impact of molnupiravir on human health was evaluated through 3 mechanisms: viral resistance, mutagenesis of SARS-CoV-2, and mutagenesis occurring in patients undergoing treatment with molnupiravir. These mechanisms, as well as the impact of vaccination, have inadvertently given rise to unforeseen challenges in the management of the COVID-19 crisis. Taking a systems view in future pandemic responses, and taking into account the evolution of the pandemic virus, may be critical to ending the pandemic at an earlier date.},

The profound global health and economic impact of COVID-19 has made the potential devastation of Disease X tangible. However, despite the insights gained from COVID-19, significant gaps remain in translating this awareness into an effective, coordinated, and pre-emptive preparedness strategy. This review advances an integrated response framework built around a One Health surveillance diagnostic therapeutic continuum. This foundational system enables real-time pathogen tracking and host immune profiling across human, animal, and environmental interfaces. Insights generated through this continuum directly inform the timely activation of non-pharmaceutical interventions, guide dynamic modeling, and enable the precise deployment of rapid medical countermeasures. Furthermore, these measures should be supported by resilient health infrastructure and equitable data sharing mechanisms, and be embedded within a governance model that prioritizes global collaboration and equity. Ultimately, mitigating Disease X requires a unified strategy that seamlessly integrates continuous monitoring, diagnostics, and treatment within a resilient and equitable operational architecture, thereby transforming pandemic preparedness from concept into reality.},

abstract = {It is acknowledged that COVID-19 pandemic triggered by SARS-CoV-2 outbreak demands the development of efficient antiviral modalities independent of traditional vaccines and antiviral reagents. Metallic nanoparticles, such as silver nanoparticles (Ag-NPs) and zinc oxide nanoparticles (ZnO-NPs), have attracted considerable attention as promising antiviral agents due to their distinctive physicochemical properties and universal antimicrobial activity. This article examines the progress made between (2021 and 2025) in the green synthesis and the antiviral applications of Ag-NPs and ZnO-NPs against Coronavirus. The environmental friendly synthesis protocols using natural plant juices have been highlighted in this article due to their lower toxicity and greater biocompatibility. Various characterization methods, such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and UV-Vis spectrophotometry, have been used to examine nanoparticle morphology, stability, and surface characteristics. The findings reveald that Ag-NPs can suppress the viral replication by interacting strongly with S proteins, thereby hindering the cellular entry of the targeted Coronavirus. In contrast, ZnO-NPs showed that they have dual purposes: direct antiviral effects and immunomodulatory effects that involve cytokine regulation. The antiviral properties and the limitations of the individual nanoparticles are significantly modified by hybrid nanocomposites. In closing, the significance of using green-synthesized Ag-NPs and ZnO-NPs as antiviral materials is tremendous and warrants further exploration for antiviral applications. Nonetheless, there are still some unaddressed areas concerning the standardization of synthesis techniques and the validation of prolonged safety. Finally, it has been proven that there is a need for collaboration between nanotechnology and green technology in the development of environmentally benign, and universal antiviral medications against any future coronavirus pandemics.},

abstract = {The COVID-19 pandemic established mRNA vaccines as a clinically validated platform for rapid vaccine development and deployment. This review summarizes recent progress in COVID-19 mRNA vaccine technology, clinical performance, immunological mechanisms, and translational applications. First-generation nucleoside-modified mRNA vaccines formulated in lipid nanoparticles demonstrated strong protection against symptomatic disease and, more durably, against severe outcomes, while variant-driven immune escape, waning protection against infection, limited mucosal immunity, and heterogeneous responses in special populations revealed important constraints. The review compares mRNA vaccines with other COVID-19 vaccine platforms and clarifies endpoint-specific correlates of protection, emphasizing the distinct roles of neutralizing antibodies, memory B cells, T-cell responses, and non-neutralizing antibody functions. It further examines unresolved issues associated with repeated vaccination, including immune imprinting and IgG4 class switching, and evaluates technological strategies designed to improve durability, breadth, delivery, and immune programming. Key innovations include optimized RNA chemistry, structure-guided antigen design, advanced lipid nanoparticle formulations, alternative delivery systems, immune-shaping adjuvant approaches, and next-generation RNA formats such as self-amplifying RNA and circular RNA. Finally, the review discusses vaccination strategies for immunocompromised individuals, pregnant and lactating women, older adults, and children, as well as the expansion of mRNA technology into respiratory virus vaccines, cancer immunotherapy, and therapeutic protein expression. These developments define mRNA technology as a modular platform whose clinical impact depends on aligning RNA architecture, delivery system, antigen design, and target population.},

abstract = {BACKGROUND: Idiopathic multicentric Castleman disease (iMCD) is a lymphoproliferative disorder characterized by dysregulated systemic immunity. Multiple cytokines had been found involved in the disease pathogenesis. Hence, involvement of multiple systems in iMCD complicates diagnosis and efficacy assessments. Although guidelines recommend anti-interleukin-6 (IL-6) agents as the primary treatment, options for second-line therapy remain indeterminate.

CASE PRESENTATION: A 65-year-old woman presented with progressive polyneuropathy and nephrotic-range proteinuria ten days after COVID-19 vaccination. Evaluation revealed multicentric lymphadenopathy, elevated IL-6, and plasmacytic-variant CD histopathology (HHV-8 negative). Concurrent Sjögren's syndrome and anti-PLA2R-negative membranous nephropathy were confirmed. After exclusion of POEMS syndrome, iMCD-NOS with intermediate severity was diagnosed. Initial rituximab-cyclophosphamide-dexamethasone therapy resulted in paradoxical neurological worsening despite declining VEGF levels. Anti-IL-6 therapy was inaccessible due to economic constraints. Single-agent rituximab was initiated and continued for nine cycles over 24 months, achieving clinical remission by January 2024 with near-normalization of inflammatory markers, resolution of proteinuria, and neurological recovery.

CONCLUSIONS: This case demonstrates that rituximab monotherapy can achieve clinical remission in iMCD-NOS with concurrent autoimmune manifestations when anti-IL-6 therapy is unavailable. The delayed response pattern-with biomarker improvement preceding clinical recovery-highlights the importance of serial VEGF monitoring and persistence with B-cell-directed therapy before concluding treatment failure.},

This crisis bears greater resemblance to Spain's 2014 Ebola response than to the early stages of the COVID-19 pandemic. A decade after Ebola, Spain has built substantially stronger HCID capacities: a network of High Level Isolation and Treatment Units, improved clinical protocols, diagnostic capacity, and more consistent technical communication. Coordination with international partners functioned effectively. However, structural challenges persist: political tensions between central and regional authorities complicated real-time operational coordination and spilled into public communication, undermining the perception of a unified, technically-led response. Finalisation of a National Preparedness and Response Plan and full operationalisation of the National Public Health Agency (AESAP) remain urgent priorities. These domestic challenges sit within a deteriorating global health financing environment, directly eroding the surveillance and response capacities that HCID containment depends upon globally. Spain's Estrategia Española de Salud Global 2025-2030, its seat on the WHO Executive Board and its commitment to increasing ODA, position it well to advocate for stronger HCID-specific frameworks internationally, building on the genuine progress this response demonstrated.},

This review summarizes the prevalence, pathophysiology, clinical presentation, and management of COVID-19-associated AKI (hereafter COVID-19 AKI). COVID-19 AKI is linked to a multisystem inflammatory syndrome and presents symptoms similar to those of AKI, which is associated with increased morbidity and death rates. The pathophysiological mechanisms of AKI include direct viral injury, cytokine storms, and systemic effects on the renin-angiotensin-aldosterone system. The diagnostic assessment of patients at risk for AKI involves screening for symptoms such as decreased urine output, fluid retention, and fatigue. In contrast, biomarkers like serum creatinine and blood urea nitrogen are used for early detection. The management strategies for COVID-19 AKI, such as avoiding nephrotoxic medications, are similar to those for AKI of other causes. Renal replacement therapy may be considered as a treatment option for severe COVID-19 AKI, particularly in cases of fluid overload, or electrolyte imbalances that cannot be managed with conservative treatments. Future research is essential to elucidate the pathophysiology, optimize diagnostic criteria, and develop targeted therapies for COVID-19 AKI. A multidisciplinary approach focusing on physical and mental health is crucial for comprehensive patient care. Addressing these gaps will necessitate substantial funding support to propel research efforts and improve patient outcomes.},

abstract = {SUMMARYClass I fusion proteins are trimeric viral membrane proteins that mediate fusion between the virion and cellular membranes. In their prefusion state, they comprise three domains: a globular "head" domain that binds the target cell receptor, a helical "stalk" domain, and a transmembrane domain (TMD) at the carboxy-terminal end that anchors the protein in the viral membrane. However, it is now evident that the role of the TMD extends beyond simple membrane anchoring. This review explores the dynamic and regulatory functions of the TMD throughout the viral life cycle. TMDs contribute to intracellular trafficking and modulate membrane fusion activity and receptor binding. During virion assembly, they facilitate the incorporation of fusion proteins into budding particles, and influence virion formation and release. Furthermore, TMDs mediate interactions between viral and host proteins, shaping the structural organization of viral complexes, and impacting cellular responses to infection. Collectively, these findings highlight the TMD as a critical determinant of viral fitness and infectivity, underscoring its potential as a novel therapeutic target.},

abstract = {From the perspective of both the host cell and the virus, cholesterol (CHO) plays a critical role during viral infection. Proprotein convertase subtilisin/kexin type 9 (PCSK9) increases the risk of cardiovascular disease by regulating plasma levels of lipoprotein(a), triglyceride-rich lipoproteins, and low-density lipoprotein cholesterol (LDL-C), and by promoting the degradation of the LDL receptor (LDLR). Emerging evidence implicates PCSK9 in the pathophysiology of several viral diseases, including human immunodeficiency virus (HIV), SARS-CoV-2, dengue virus (DENV), and hepatitis viruses. Two monoclonal antibody PCSK9 inhibitors (PCSK9i), evolocumab (Repatha[®]) and alirocumab (Praluent[®]), are approved by the Food and Drug Administration (FDA) for managing atherosclerotic risk. However, despite preclinical studies suggesting that these inhibitors and other CHO-lowering medications may interfere with viral replication, their therapeutic application as antivirals remains limited due to various restrictions. Naturally occurring compounds such as curcumin, berberine, quercetin, and polyphenols have demonstrated PCSK9-modulating and antiviral properties in preclinical models against viruses including HIV, hepatitis viruses, SARS-CoV-2, DENV, herpes simplex virus, human cytomegalovirus, and Epstein-Barr virus. Crucially, the majority of evidence for these natural substances remains preclinical, derived from in vitro and animal studies. The contribution of PCSK9 inhibition to the reported antiviral effects remains unclear, as pleiotropic mechanisms may be involved. Therefore, rather than being clinically proven substitutes for licensed PCSK9-targeted treatments, these molecules should be considered experimental or maybe supplementary medicines. This review examines the current preclinical evidence for natural inhibitors of PCSK9 and their antiviral properties, discusses clinical assessments to date, and considers the potential future role of naturally occurring PCSK9i in antiviral development, acknowledging the substantial research gaps that remain.},

abstract = {Three of the great public health challenges of our time converge at the hippocampus. The first, dementia, most commonly in the form of Alzheimer's disease, is well known to cause progressive hippocampal damage, resulting in the memory loss associated with the illness. The second, COVID-19 infection, has thus far been linked to hippocampal alterations across multiple studies. Lastly, the third, opioids-especially in the setting of misuse-have been associated with acute and persistent hippocampal injury; this review focuses on the collection of pre-clinical, clinical, and epidemiologic observations supporting this final relationship. Basic science work dating back decades has demonstrated a hypermetabolic response to opioids and associated damage to the hippocampus. The earliest cases recognized as opioid-associated amnestic syndrome (OAS) were subsequently identified in 2012 and reported as part of larger case series several years later. In 2019, a related but more fulminant syndrome involving cerebellar, hippocampal, and basal nuclei transient edema with restricted diffusion (CHANTER) was first described. From these investigations, a growing body of data has since emerged to suggest that regular opioid use, particularly at higher doses or potency, may be connected to a reduction in hippocampal volume and greater risk of dementia. This review begins with a synthesis of data supporting the underlying pathological mechanisms of opioid-associated hippocampal injury (OAHI), then covers the clinical spectrum of this phenomenon. Lastly, we will close with implications of OAHI that warrant further study, including the future epidemiologic impact on related cognitive disorders in the wake of the opioid epidemic and potential therapeutic applications of opioid antagonism for mild cognitive impairment.},

abstract = {Concurrent infection of humans by multiple distinct viruses is a common biological phenomenon with important consequences for virus-host interactions. While coinfection refers to the simultaneous infection of an individual or cell with two or more viruses, superinfection denotes the establishment of a secondary infection following a primary one, in which the initial infection influences the susceptibility, replication, or outcome of the secondary infection. Virus-virus interactions can be antagonistic, facilitative, dependent/assisted, or neutral. Antagonistic interactions include superinfection exclusion, whereby a primary virus prevents or restricts secondary infection of the same cell, securing access to host resources and stabilizing replication while limiting genetic and viral diversity. In contrast, facilitative viral interactions arise when one virus disrupts tissue barriers, suppresses immune responses, or remodels cellular pathways, thereby increasing susceptibility to additional viral infections. These interactions intersect with fundamental viral strategies, including the generation of genetically diverse RNA virus quasispecies that promote rapid adaptation and the deployment of DNA virus immunoevasins that interfere with antigen presentation and host immune recognition. While each of these processes has been extensively studied individually, their combined impact during coinfection remains poorly defined. In this review, we synthesize current knowledge on virus-virus interactions, viral diversity, and immune evasion in the context of multi-viral infections. We focus on how interactions at cellular and tissue levels shape infection outcomes, influence viral evolution, and contribute to virus-host coevolution. Finally, we also highlight key gaps in our understanding of viral interference and cooperation and discuss emerging approaches needed to define the spatiotemporal dynamics of coinfection in vivo.},

We identified 222 qualitative factors from 32 studies, and 114 quantitative factors from 30 studies. Qualitative studies frequently reported individual and group influences, particularly beliefs and attitudes about vaccine effectiveness and safety, and the role of healthcare professionals in decision-making. Quantitative studies highlighted sociodemographic influences, including older age, ethnicity, and lower social/economic deprivation. Factors found to be associated with vaccination intention vs. uptake were inconsistent, though these findings should be interpreted cautiously given the modest number of studies addressing this issue.},

abstract = {BACKGROUND: Respiratory syncytial virus (RSV) is a major cause of acute lower respiratory tract infections (ALRIs) in children. To guide policymaking on controlling RSV-associated ALRIs (RSV-ALRIs) in China, we estimated the national, regional, and provincial burdens of RSV-ALRIs and associated hospitalizations for children under 5 years old.

METHODS: We systematically identified publications about RSV-ALRIs in China with epidemiological data before 2020. We compared seasonality data from this period with data during the COVID-19 epidemic. We built a dataset to assess RSV-ALRI burden by age and region, using a generalized linear mixed-effects model and a conceptual proportionality framework to assess hospitalization rates. A risk factor-based model were used to estimate regional and provincial RSV-ALRI incidence.

FINDINGS: Children aged 0 to 12 months had the highest risk of RSV-ALRI and associated hospitalization. Provincial variations existed, with some southern provinces exhibiting higher incidence and some western provinces higher hospitalization rates. The COVID-19 epidemic shifted RSV hospitalization peaks to early autumn (Guangdong, Shanghai), whereas Hubei and Shandong demonstrated delayed peak onset compared with the pre-pandemic period.

INTERPRETATION: Our study of the burden RSV-ALRIs in China identified obvious heterogeneity by age and region. These findings highlight the need for targeted RSV vaccination strategies and resource allocation prioritizing high-risk groups and areas.

This narrative review explores current challenges and evidence-based strategies for optimising ICU supply chains. Issues such as unpredictable demand, manual stock tracking, procurement inefficiencies and limited staff training often contribute to stockouts, expired supplies and delayed interventions. The COVID-19 pandemic further exposed systemic vulnerabilities, emphasising the need for resilient, technology-driven supply systems. A comprehensive literature search (2004-2025) was conducted across PubMed, Scopus, Web of Science and Google Scholar using keywords related to ICU inventory, artificial intelligence (AI) forecasting, radio frequency identification (RFID), procurement and digital health logistics. Findings were synthesised into thematic categories addressing core problems and interventions. Key strategies include implementing automated tracking systems, adopting AI-driven demand forecasting, standardising procurement policies, training ICU staff in inventory best practices and establishing emergency buffer stock. Emerging technologies such as digital twins and blockchain are highlighted for their potential to enhance transparency, responsiveness and planning accuracy. Additionally, fostering multisourcing supplier partnerships and optimising ICU storage space can further enhance system agility and reduce waste. In conclusion, ICU supply chains must evolve from reactive, manual systems to proactive, data-driven frameworks. Hospitals should invest in digital infrastructure, staff training and ethical procurement models to build resilient, cost-effective and patient-centred supply chains.},

Co-infections pose diagnostic challenges due to overlapping clinical symptoms and immune modulation, which may exacerbate disease severity. Moreover, antibodies generated from prior virus infections may influence the outcome of subsequent infections through mechanisms such as cross-reactivity and antibody-dependent enhancement (ADE). This review summarises current knowledge on the clinical manifestations and immunological consequences of co- and subsequent infections involving SARS-CoV-2 and arboviruses. Emphasis is placed on underlying pathophysiological mechanisms, including cross-reactivity and ADE, that shape host immune responses.

abstract = {The maternal-fetal interface represents a dynamic immunological frontier where pregnancy outcomes are determined by the delicate balance between host defense and microbial pathogenesis. Vertical transmission of pathogens across the placental barrier can lead to devastating consequences including fetal loss, stillbirth, prematurity, and congenital anomalies. The classic TORCH acronym encompasses Toxoplasma gondii, Other agents, Rubella virus, Cytomegalovirus, and Herpes simplex virus, though emerging viruses including Zika virus and SARS-CoV-2 have expanded this spectrum. This review synthesizes current understanding of molecular mechanisms underlying vertical transmission, emphasizing the placenta's multi-layered defense system encompassing the syncytiotrophoblast physical barrier, specialized decidual immune cell populations including decidual natural killer cells and macrophages, and constitutive antimicrobial signaling pathways focusing on the placenta's multi-layered defense system encompassing the syncytiotrophoblast physical barrier, specialized decidual immune cell populations including decidual natural killer cells and macrophages, and constitutive antimicrobial signaling pathways. Concurrently, we examine pathogen strategies to subvert these defenses through receptor manipulation, immune evasion, and intracellular replication niches. A major focus is dedicated to the impact of proteomics and single-cell multi-omics in deconvoluting the host-pathogen interactome and identifying biomarkers of fetal injury. Recent seroprevalence studies demonstrate that younger women represent the most susceptible population to acute TORCH infections, highlighting the need for targeted screening programs. This synthesis provides a framework for developing precision diagnostics and targeted interventions to prevent vertical transmission and reduce the global burden of congenital infections.},

AIMS: This study analyzes the pricing policies and costs of medical oxygen in Quebec, provides elements of international comparison, and explores the potential savings through the optimization of oxygen therapy practices.

MATERIALS AND METHODS: It combines a narrative literature review, an analysis of administrative and financial documents, as well as administrative data obtained from representatives of the healthcare sector in Quebec.

RESULTS: The literature review highlights the challenges of producing, storing, and distributing medical oxygen, which have been accentuated by the COVID-19 pandemic. A very large disparity in pricing policies is also noted among healthcare systems, especially when cylinders are predominantly used. In Quebec, costs vary according to production methods, logistics, and contractual clauses. Optimizing oxygen therapy practices would allow significant savings, particularly by reducing oxygen consumption through various strategies.

DISCUSSION: The study shows the complexity of managing medical oxygen costs, amplified by limited competition and rigid contractual clauses. International comparison highlights the importance of infrastructure, while optimizing oxygen therapy practices offers significant savings potential. To reduce costs, it is recommended to improve distribution management, adopt more flexible contractual clauses, and strengthen competition.

CONCLUSION: To optimize medical oxygen use, actions to undertake from managers and clinicians are highlighted.},

abstract = {Neurodegenerative diseases (NDDs) are multifactorial disorders with increasing evidence implicating viral infections in their pathogenesis. However, current reviews often catalog virus-disease associations without integrating this evidence into a unified conceptual model that also accounts for the therapeutic potential of viral platforms. This review investigates recent literature to propose a "dual-role" model for viruses in NDDs. We analyze how diverse viruses (e.g., HSV-1, HIV, EBV, and SARS-CoV-2) converge on shared pathogenic pathways, including protein misfolding, chronic neuroinflammation, and mitochondrial dysfunction, across different NDDs. Paradoxically, engineered viral vectors derived from neurotropic viruses are being investigated as tools for targeted gene therapy. To address these therapeutic applications of viruses, this review also provides an in-depth report of the various viral vector technologies developed. The approaches involved in designing rationally engineered viral vectors based on various adeno-associated virus serotypes through rational design, directed evolution and machine learning strategies, as well as the lentiviral and herpes simplex virus-based platform are described. Different strategies that have been used to incorporate large and/or small payloads such as gene replacement, RNA interference, microRNA cassettes, CRISPR-based gene editing (base editing, prime editing, CRISPRa and CRISPRi) and the double AAV systems to deliver larger transgene cassette have also been reviewed. This review further includes various routes of administration including intrathecal, intracerebroventricular and convection-enhanced delivery with the use of Focused Ultrasound. The constraints imposed by the Blood-Brain Barrier are discussed, especially the approach using receptor-mediated transcytosis for crossing. The review also critically evaluates obstacles toward clinical translation of viral vectors due to various factors including immunogenicity, the presence of pre-existing neutralising antibodies and dose-dependent toxicity, illustrated by the fatal outcome of ASPIRO and DMD trials. Finally, this review concludes with other promising non-viral approaches such as lipid nanoparticle and extracellular vesicles. Future research needs include long-term studies to investigate causality and extensive safety optimization of viral vectors.},

abstract = {BACKGROUND: Sarcopenia, assessed via computed tomography (CT), is an emerging prognostic tool in critically ill, pulmonary, and geriatric patients. Laboratory inflammatory markers such as C-reactive protein (CRP), interleukin-6 (IL-6), and neutrophil-to-lymphocyte ratio (NLR) are routinely obtained in these populations. Whether CT-assessed sarcopenia combined with laboratory markers offers superior prognostic accuracy over either measure alone remains unclear.

OBJECTIVES: To systematically evaluate the prognostic value of CT-assessed sarcopenia, alone or combined with laboratory inflammatory/nutritional markers, for predicting mortality, mechanical ventilation duration, and ICU length of stay in critically ill, pulmonary, and geriatric patients.

METHODS: MEDLINE/PubMed, Scopus, Embase, and Cochrane Library were searched from inception to December 2024. Observational studies (prospective or retrospective cohorts, case-control) that reported CT-based sarcopenia assessment alongside at least one laboratory inflammatory marker and at least one clinical outcome were included. Two reviewers independently screened studies, extracted data, and assessed methodological quality using the Newcastle-Ottawa Scale (NOS). Random-effects meta-analysis was performed; heterogeneity was assessed using the I² statistic.

RESULTS: Twenty-five studies encompassing 12,347 patients were identified. The pooled odds ratio for mortality in sarcopenic versus non-sarcopenic patients was 2.28 (95% CI: 1.83-2.83; I² = 22.1%) across critically ill ICU cohorts. In COVID-19 pulmonary populations, pooled OR for in-hospital mortality with low skeletal muscle mass was 5.84 (95% CI: 1.07-31.83). CT-derived muscle measurements correlated inversely with CRP (r = -0.315), fibrinogen (r = -0.392), D-dimers (r = -0.363), and WBC count (r = -0.287). Combined CT-sarcopenia and inflammatory marker models outperformed conventional scoring systems (APACHE II, SOFA, CURB-65, PSI).

CONCLUSIONS: CT-assessed sarcopenia, when integrated with laboratory inflammatory markers, provides a robust, mechanistically grounded, and clinically accessible multimodal prognostic framework across critically ill, pulmonary, and geriatric populations.},

In this review, we discuss how aging-related alterations in adrenergic pathways affect immune cell differentiation and cytokine networks, with particular emphasis on β2-adrenergic control of the Th17/regulatory T cell balance through cAMP-dependent mechanisms interacting with cytokine-driven STAT signaling. Chronic sympathetic stimulation and β-adrenergic desensitization weaken these regulatory constraints, favoring pro-inflammatory immune trajectories and loss of immune tolerance. Finally, we propose Long COVID as a paradigmatic condition in which pre-existing inflammaging and autonomic vulnerability are amplified by viral infection, leading to persistent inflammation, impaired immune regulation, and increased susceptibility to autoimmune manifestations.},

abstract = {Cough is a common and physiologically informative component of respiratory morbidity, but its potential for diagnosing and monitoring disease is not thoroughly investigated. This systematic review synthesised the literature on algorithmic and statistical models analysing cough acoustics for diagnosing or monitoring respiratory conditions. Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, five databases (PubMed, Embase, Scopus, Web of Science and CENTRAL) were systematically searched for studies published from January 2010 to June 2025. Eligible studies performed quantitative acoustic feature analysis of human coughs using statistical, machine learning or deep learning models and reported diagnostic or prognostic performance. 89 studies from 34 countries were assessed, covering cough detection (n=31), disease classification (n=55) and disease severity prediction (n=3), reflecting potential applications in disease monitoring. Deep learning approaches, especially convolutional and recurrent networks, were predominant (n=56) and tended to achieve the higher accuracies, although machine learning ensemble methods and logistic regression also demonstrated strong performance, particularly with well-engineered features. Across different diseases, sensitivities and specificities were often reported to be ≥90%, notably for tuberculosis, asthma and COVID-19. However, methodological weaknesses were common, with only 11.2% of studies introducing external validation, 71.1-87.6% demonstrating high risk of bias (according to PROBAST-AI) and most based on small, homogeneous or crowdsourced cohorts with limited generalisability. These limitations contribute to inflated internal performance and uncertainty about real-world applicability. Cough acoustic biomarkers hold promise as an adjunctive tool for screening and longitudinal monitoring in low-resource environments. Nevertheless, widespread implementation will require large, multicentre validation, standardised calibration, bias control and incorporation into privacy-preserving workflows.},

It has emerged as a pivotal mechanism implicated in various diseases, including cancer, chronic kidney diseases (CKD), neurodegenerative disorders, pulmonary fibrosis, chronic wounds, and viral infections such as COVID-19. This chapter presents a comprehensive overview of the molecular underpinnings of ferroptosis, emphasizing its key regulators-iron metabolism, lipid peroxidation pathways, and antioxidant defenses such as GPX4 and system Xc[-]. We explore recent advances highlighting the therapeutic potential of ferroptosis modulation across multiple pathological contexts. In cancer, ferroptosis inducers have shown efficacy in overcoming drug resistance and enhancing immunotherapy. In contrast, inhibition of ferroptosis offers protective effects in neurodegenerative diseases, ischemia-reperfusion injury, and chronic inflammatory conditions. Applications in nanomedicine have further enabled targeted delivery of ferroptosis modulators, expanding their clinical relevance. The chapter also discusses emerging roles of ferroptosis in wound healing, CKD and pulmonary fibrosis, with particular attention to COVID-19-related lung injury. Finally, we evaluate current therapeutic strategies, safety considerations, and potential clinical applications, along with future directions including biomarker development and personalized medicine. Our aim is to provide a unified perspective on ferroptosis as a disease-modifying mechanism and to highlight its growing importance as a therapeutic target across diverse clinical disciplines.},

The efficacy of this vaccine platform relies on the induction of powerful and coordinated innate and adaptive immune responses. A deep understanding of the mechanisms of action by which mRNA-LNP vaccines drive protective immunity is crucial for advancing the development of next-generation mRNA vaccines with improved immunogenicity and tolerability. A flurry of recent studies has shed light on aspects of this vaccine modality's modus operandi. Nonetheless, key gaps in knowledge remain, including understanding how LNPs are sensed by the immune system and exert their adjuvant activity, identifying the specific signals and cellular pathways critical for eliciting protective immune responses and determining whether it is feasible to uncouple vaccine immunogenicity and reactogenicity. Here we review the known and unknown features of the immunological mechanisms of mRNA-LNP vaccines for infectious diseases. Furthermore, we discuss how the components of this vaccine platform can be modified to fine-tune immune responses against challenging pathogens for which effective vaccines do not exist or need improvement.},

Merbecoviruses were once thought to rely exclusively on dipeptidyl peptidase 4 for cell entry, but recent discoveries have revealed that several members can also engage with angiotensin-converting enzyme 2 or aminopeptidase N, expanding their receptor repertoire and potential host range. Here we summarize recent advances in understanding of the receptor usage of merbecoviruses and examine how these insights inform pandemic preparedness and risk assessment. We discuss the development of targeted diagnostics, broad-spectrum antivirals and vaccines, including pan-coronavirus strategies. Together, these advances provide a foundation for predictive surveillance and rational countermeasure design, enabling earlier detection and more effective containment of future merbecovirus spillover events before they escalate into epidemics.},

This paper supports the establishment of routine mortality surveillance as a core function of essential public health services, emphasising the need for integration with civil registration and vital statistics (CRVS) systems. By leveraging existing frameworks and proposing a Theory of Change (ToC), we outline critical linkages between CRVS and mortality surveillance that enhance data accuracy, timeliness and utility for public health decision-making. The paper provides examples across key enablers-policies, agreements and legislation; infrastructure; governance, funding and resources; and people and organisational culture-that facilitate these linkages. We also present examples from initiatives like the Africa CDC's Mortality Surveillance Programme to illustrate effective strategies in low- and middle-income countries (LMICs). The ToC serves as a blueprint for stakeholders to implement strategic interventions aimed at overcoming barriers to linking systems and data integration and utilisation. Ultimately, this paper underscores the importance of coordinated efforts among national public health agencies, civil registration authorities and other stakeholders to improve mortality data systems globally. By addressing these systemic challenges through enhanced collaboration and technological innovation, we can significantly advance public health outcomes and policy formulation in response to future health crises.},

We also outline in silico workflow encompassing antigen selection, consensus sequence generation. The first step in the workflow is to check the conserved antigenic domains and epitopes. Bioinformatic analysis supported antigen identifying and its targets using appropriate tools, followed by consensus sequence creation through multiple sequence alignment using specific platforms. mRNA constructs were optimized via codon adaptation, GC content balancing, and secondary structure analysis. Delivery strategies also were briefly assessed between the FDA approved systems. Lipid nanoparticle formulation, were incorporated into the design to theoretically enhance stability and cellular uptake. Robust protein expression both in vitro and in vivo assessments further suggested the immunogenic potential along with providing a computational basis for future preclinical evaluation. This study review provides a step-by-step protocol that clarifies and simplifies the design process for linear mRNA constructs. The framework translates complex design considerations into actionable, sequential guidelines, enabling researchers to rationally design vaccine candidates in silico. Certainly, we support accelerated design efforts against current threats, while also serving as a preparedness blueprint for future pandemics.},

abstract = {INTRODUCTION: Occupational health and safety (OHS) practices witnessed profound changes worldwide during the COVID-19 pandemic. The pandemic exposed critical vulnerabilities in workplace preparedness, particularly among workers in high-exposure and essential service sectors.

METHODS: A systematic review was conducted following PRISMA guidelines using PubMed, Google Scholar, DOAJ, ResearchGate, and gray literature sources. Studies published between January 2020 and December 2024 focusing on occupational exposure, workplace transmission, OHS guidelines, and workforce health during COVID-19 were included.

RESULTS: Healthcare workers experienced the highest occupational risk due to sustained patient contact and aerosol-generating procedures, accompanied by significant psychological distress and burnout. Essential workers, manufacturing sectors, retail workers, educators, and informal sector workers also faced substantial occupational and socioeconomic challenges. Workplace interventions including engineering controls, administrative controls, PPE use, vaccination strategies, and digital surveillance tools reduced workplace transmission. Remote-enabled sectors demonstrated lower infection risk but increased mental health concerns.

DISCUSSION: The COVID-19 pandemic transformed traditional OHS frameworks by integrating infectious disease preparedness, vaccination strategies, mental health support, and workplace surveillance into occupational safety systems. The findings emphasize the need for integrated, adaptive, and equitable OHS frameworks aligned with public health preparedness to strengthen workforce resilience against future pandemics.},

This narrative review examines the pandemic as a disruption of hemato-oncology care delivery rather than only as a source of excess infection-related morbidity. It synthesizes evidence on diagnostic access, patient flow, treatment prioritization, infection-control circuits, day-hospital organization, inpatient access, telemedicine and hybrid follow-up, supportive care, vaccination, antiviral pathways, and high-complexity care delivery. The review distinguishes between temporary crisis restrictions, harmful diagnostic and therapeutic delays, and durable organizational adaptations that may remain relevant after the acute pandemic period. Evidence from cancer-service disruption studies, hemato-oncology outcome registries, telemedicine cohorts, and European hematopoietic cell transplantation activity surveys indicates that hemato-oncology care pathways were reorganized and selectively redirected during the pandemic, while selected components recovered through structured triage, protected circuits, remote review of stable patients, and individualized timing of transplantation and cellular therapy. The post-pandemic priority is not to preserve restrictive crisis practice, but to retain the organizational discipline generated by the crisis: protected diagnostic capacity, risk-stratified access, selective hybrid care, rapid infectious-risk assessment pathways, disciplined day-hospital scheduling, and reserved in-person capacity for unstable, procedure-dependent, or curative-intent patients. These adaptations should be maintained only insofar as they improve access, safety, and continuity of care without normalizing delayed diagnosis or undertreatment of aggressive disease.},

abstract = {The recent document from the American Heart Association updates the guidelines on the diagnosis and management of Kawasaki disease (KD), a severe acute systemic inflammatory and febrile illness with mucocutaneous manifestations and lymph node involvement primarily affecting children under 5 years of age. Coronary artery involvement, with dilation and aneurysms in approximately 25% of patients, and cardiovascular system involvement make KD the most common systemic vasculitides and the leading cause of acquired heart disease in pre-school children living in developed countries. Classic KD is diagnosed based on established clinical and laboratory criteria, which exclude other similar conditions. The etiology and pathogenesis of KD remain unknown, with the disease affecting genetically susceptible children through an immune-mediated mechanism. The leading theory is that an unidentified trigger initiates a multi-organ inflammatory pathological cascade, sometimes resulting in incomplete or atypical forms in younger patients. For this reason, the American guidelines review KD diagnostic criteria, cardiac imaging techniques (echocardiography, coronary computed tomography, magnetic resonance imaging), specific therapies (intravenous immunoglobulin, aspirin, and additional treatments for resistant cases), management of myocardial infarctions, and the transition of care from pediatric to adult age. This review article also highlights future research areas, the role of inflammation, the development of differential diagnostic algorithms for multisystem inflammatory syndrome in children associated with SARS-CoV-2 infection, and the use of new oral anticoagulants. Lastly, the most recent data on the long-term course of the disease and the regression of coronary aneurysms are revisited.},

Iron deficiency remains the most common and potentially correctable cause of perioperative anemia. This narrative review examines various approaches to perioperative anemia, strategies to minimize reliance on ABT, and alternatives within the PBM paradigm. Evidence supports the use of iron therapy, erythropoiesis-stimulating agents, antifibrinolytic strategies, and blood conservation techniques to reduce transfusion requirements and improve clinical outcomes. Lessons from the COVID-19 pandemic highlight PBM as a framework to enhance transfusion safety and sustainability. Broader implementation of PBM may improve patient outcomes, reduce unnecessary transfusions, and preserve scarce blood resources.},

abstract = {BACKGROUND: Monoclonal antibodies (mAbs) initially played a major role in outpatient COVID-19 management by providing rapid passive immunity and reducing progression to severe disease. However, continuous SARS-CoV-2 evolution progressively compromised the effectiveness of several anti-spike products. This narrative review summarizes the trajectory of COVID-19 mAbs across three phases: early clinical efficacy, loss of efficacy due to immune escape, and future directions.

METHODS: We conducted a narrative review focusing on mechanisms of action, pivotal clinical trials, and real-world effectiveness of neutralizing anti-spike mAbs and host-directed immunomodulatory mAbs. Emphasis was placed on the impact of variants-especially Omicron-on susceptibility and clinical use, as well as on emerging next-generation platforms.

RESULTS: First-generation neutralizing mAbs substantially reduced the hospitalization rates during the Alpha and Delta waves, while immunomodulatory mAbs became standard options for the hyperinflammatory phase in hospitalized patients. With the emergence of Omicron and its sub-lineages, extensive immune escape led to marked reductions in neutralization for many earlier anti-spike agents and consequent restrictions in use. Later-generation approaches targeting more conserved epitopes provided temporary solutions but were also challenged by ongoing antigenic drift. Host-directed immunomodulators retained clinical relevance because their mechanism is independent of viral spike mutations.

CONCLUSIONS: The clinical role of monoclonal antibodies in COVID-19 has been dynamic and increasingly constrained by viral evolution. Future strategies should prioritize broadly neutralizing antibodies targeting conserved epitopes, innovative delivery platforms, and integration with real-time surveillance to preserve clinical utility in the endemic phase and improve preparedness for future outbreaks.},

Autoantibodies targeting IFN-I (anti-IFN-I AAbs) have emerged as key pathogenic factors in severe coronavirus disease 2019 (COVID-19) and are detectable in systemic lupus erythematosus (SLE), a prototypic IFN-driven autoimmune disease. Here we compare the prevalence and clinical impact of anti-IFN-I autoantibodies (Aabs) in COVID-19 and SLE based on a structured review of 53 studies from 2014 to 2025 and highlight the clinical associations and therapeutic opportunities presented by these autoantibodies. In COVID-19, neutralising anti-IFN-α and/or anti-IFN-ω AAbs were consistently associated with severe disease and impaired antiviral responses, particularly in older male populations. In SLE, anti-IFN-α AAbs were variably detected; neutralising antibodies were associated with reduced interferon gene signatures in some cohorts but inconsistent correlations with disease activity. Therapeutically, anti-IFN-I AAbs in COVID-19 may inform risk stratification and early antiviral strategies, whereas in SLE, IFN-α blockade, including IFN-α kinoid vaccination, demonstrates modulation of IFN signatures but variable clinical benefit. Notably, these findings reveal an immunological paradox: the same neutralising mechanism that impairs antiviral defence in COVID-19 may attenuate chronic IFN-driven inflammation in SLE. Taken together, anti-IFN-I AAbs exert context-dependent effects: pathogenic in acute viral infection yet potentially modulatory in chronic IFN-driven autoimmunity. Prospective longitudinal studies are required to further clarify their translational utility and long-term clinical impact.},

At the same time, non-communicable disease burdens, including obesity, type II diabetes mellitus, disruption of chronic disease care, mental health disorders and increased problematic digital use, intensified during and after the pandemic period. Antimicrobial resistance (AMR) remained a major cross-cutting threat because it undermines the effective treatment of infections and weakens emergency preparedness.

Across these topics, recurring themes included vaccination gaps, fragmented surveillance, disruption of routine care, health system inequities, misinformation and insufficient preparedness for cross-border threats. The review supports integrated surveillance, continuity plans for essential services, stronger vaccination and risk-communication strategies and sustained AMR stewardship within a One Health framework. Coordinated action across public health, primary care, mental health and chronic disease policy is essential for future resilience.},

abstract = {BACKGROUND/OBJECTIVES: Ozone therapy has been proposed across multiple clinical conditions based on hormetic, antioxidant, and immunomodulatory effects, but its efficacy and safety remain controversial. We conducted an umbrella review to appraise the effectiveness and safety of ozone therapy using evidence from meta-analyses of randomized controlled trials (RCTs).

METHODS: We searched MEDLINE, Web of Science, Embase, and the Cochrane Library from inception to 14 February 2025, with an updated search performed on 9 May 2026. Eligible studies were systematic reviews with meta-analyses comparing ozone therapy with non-active controls, including placebo, sham, saline, or standard care. Methodological quality was evaluated with AMSTAR-2 and certainty of evidence with GRADE.

RESULTS: Of 1243 records identified, seven meta-analyses representing four clinical indications (chronic periodontitis, COVID-19, diabetic foot ulcers, and impacted mandibular third-molar surgery) were included. In chronic periodontitis, evidence was mixed: one meta-analysis found no significant adjunctive benefit, whereas a more recent meta-analysis reported improvements in probing depth and gingival index, but not in bleeding on probing, plaque index, or clinical attachment level. For COVID-19, ozone therapy reduced PCR positivity at follow-up (RR 0.07; 95% CI 0.01-0.34), although this was considered a clinically non-important surrogate endpoint, and showed no significant benefit for hospital stay, intensive care unit admission, or mortality. For diabetic foot ulcers, ozone therapy was not superior to control treatment for ulcer healing (RR 1.69; 95% CI 0.90-3.17) or reduction in ulcer area. In third-molar surgery, ozone therapy did not reduce swelling or improve mouth opening, but was associated with improved short-term quality of life and reduced analgesic use. Safety outcomes were inconsistently reported, and available data did not allow firm conclusions regarding adverse events. The certainty of evidence was low or very low for all outcomes.

CONCLUSIONS: Despite mechanistic plausibility, current meta-analytic evidence from RCTs remains inconsistent, methodologically fragile, and largely based on low- or very low-certainty findings. Routine clinical use is not justified pending adequately powered, blinded RCTs with standardized dosing and delivery, patient-centered endpoints, and rigorous safety monitoring.},

abstract = {In Africa, the disease burden of diarrheal and respiratory diseases is amplified by limited surveillance capacity, diagnostic limitations, and socioeconomic inequalities. In rapidly urbanizing settings such as Kigali (Rwanda), integrating wastewater-based epidemiology (WBE) into existing surveillance systems offers a promising strategy for generating real-time epidemiological intelligence, identifying community-level hotspots, and addressing gaps in traditional reporting systems. Gastrointestinal and respiratory infections remain major causes of morbidity and mortality globally, particularly in low- and middle-income countries (LMICs), where traditional clinical surveillance systems frequently underreport the true disease burden. This systematic review synthesizes current evidence on the detection of gastrointestinal and respiratory pathogens in wastewater and evaluates the utility of WBE for early warning and public health action. A narrative review approach was used to identify peer-reviewed literature, global health reports, and surveillance studies focusing on the wastewater detection of gastrointestinal and respiratory pathogens. Databases including PubMed, Scopus, and Google Scholar were searched for studies published between 2000 and 2026. The search yielded 1247 records, of which 312 duplicates were removed. After title/abstract screening, 228 full-text articles were retrieved and assessed for eligibility. After a detailed evaluation, 108 studies were excluded for the following reasons: absence of pathogen-specific wastewater data (n = 46), a focus on environmental monitoring without public health relevance (n = 25), insufficient methodological description (n = 21), or other eligibility limitations such as a lack of primary data (n = 16). WBE provides a non-invasive, cost-effective approach for monitoring symptomatic and asymptomatic infections. Challenges involve variability in sampling, environmental factors affecting viral decay, and differences in laboratory workflows. WBE is a powerful complement to traditional infectious disease surveillance, offering early warning capabilities, population-level coverage, and real-time insights into pathogen circulation. Integrating WBE into surveillance programs, especially in LMICs such as Rwanda, can significantly strengthen epidemic preparedness, guide resource allocation, and improve outbreak response. Sustained investment in laboratory capacity, standardized protocols, and multisector collaboration is essential to fully leverage WBE for public health protection.},

abstract = {Background/Objectives: Healthcare workers play a critical role in vaccination programs, yet vaccine hesitancy has been widely reported even among this group during the Coronavirus disease 2019 (COVID-19) pandemic. Previous studies have primarily focused on identifying factors associated with vaccine acceptance, offering limited insight into the processes underlying decision-making. This study aimed to synthesize qualitative studies on healthcare workers' COVID-19 vaccination experiences to develop a comprehensive understanding of their decision-making processes. Methods: A qualitative meta-synthesis was conducted using the thematic synthesis approach proposed by Thomas and Harden. Electronic databases including PubMed, Embase, and CINAHL were searched for qualitative studies published up to February 2026. Thirteen studies were included following PRISMA guidelines. Data were analyzed through line-by-line coding, followed by the development of descriptive and analytical themes. Results: Four analytical themes were identified: (1) vaccination as a dynamic risk-benefit negotiation process, (2) trust as a central mechanism shaping information interpretation, (3) socially embedded and relationally negotiated decision-making, and (4) moral identity as a driver of vaccination behavior. Healthcare workers' vaccination decision-making was not a static choice but an evolving process shaped by continuous appraisal of risks and benefits, filtered through trust in information and institutions, influenced by social interactions, and guided by professional identity and ethical responsibility. Conclusions: Healthcare workers' vaccination decision-making is a multidimensional process embedded in cognitive, social, and ethical contexts. Interventions should move beyond individual-level approaches and instead focus on building trust, leveraging social networks, and reinforcing professional identity with implications for future public health crises.},

Despite substantial progress in vaccine development, durable field protection is still inconsistent. In this narrative review, this narrative review synthesizes current knowledge on PEC vaccine design from three connected perspectives: antigenic breadth, mucosal immunity, and translational evaluation. The economic and virological context of PEC vaccine development is first summarized, including the recurrent production burden of PECs, coronavirus genome organization, structural proteins, and the central role of the spike protein in receptor engagement, membrane fusion, and neutralizing antibody induction. Key issues are then discussed, including how spike diversity, conformational stability, epitope accessibility, glycan shielding, and antigen matching influence protective breadth; why intestinal secretory IgA, mucosal immune-cell trafficking, local memory responses, and lactogenic immunity should be prioritized as biologically relevant endpoints; and how delivery route, adjuvant selection, and platform design shape response quality. Current evidence on recombinant protein, viral-vectored, nanoparticle, virus-like particle, probiotic, plant-derived, and mRNA-based approaches is compared with attention to both promise and current evidentiary and translational limitations. The available literature suggests that future progress in PEC vaccinology is likely to depend less on platform novelty alone than on integrated vaccine designs that align antigen selection, mucosal delivery, maternal-neonatal protection, heterologous challenge, manufacturability, and field applicability.},

It also seeks to evaluate the impact of the COVID-19 pandemic on maternal attitudes and behaviors regarding vaccination.

METHODS: The analysis involved a review of existing literature and studies to evaluate the level of vaccine acceptance among pregnant women before and after the COVID-19 pandemic. Factors contributing to vaccine hesitancy, including misinformation, lack of knowledge, and the influence of healthcare professionals, were examined.

RESULTS: The findings indicated that, despite scientific evidence supporting the safety and efficacy of vaccines during pregnancy, public concerns remain about their impact on the developing fetus. The outbreak of the COVID-19 pandemic has increased awareness of the risk of infectious diseases, but at the same time, its impact on vaccination rates among pregnant women is ambiguous and geographically diverse. Misinformation and decreased access to healthcare during the pandemic negatively affected vaccine uptake. Trustworthy information provided by healthcare professionals emerged as a key factor in promoting vaccine acceptance.

CONCLUSIONS: To improve vaccination rates among pregnant women, it is essential to provide clear, evidence-based information through healthcare professionals, particularly those directly caring for pregnant women. Educational campaigns should address concerns calmly and without judgment, emphasizing the safety and benefits of vaccinations. Enhanced access to healthcare and vaccinations, along with strategic information dissemination, can significantly improve vaccine acceptance during pregnancy. Lessons learned from past pandemics should be incorporated into the development of healthcare strategies aimed at implementing recommended vaccinations for pregnant women in the future.},

abstract = {Introduction: Inequities in access to medicines persist for asylum seekers, refugees, and undocumented migrants in Europe. For vaccines, access gaps not only exist for these groups in childhood routine immunization, but also for life-course and catch-up vaccinations. As part of a broader project examining access to medicines and vaccines for migrants across all stages of the migration cycle, this scoping review synthesizes evidence on the determinants of access to vaccines. Methods: We conducted a scoping review across PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Database of Systematic Reviews, Scopus, and grey literature sources, covering the period 2000-2024. Sources were eligible if they addressed access to vaccines among migrants. We examined access to vaccines along the life course, and across phases of the migratory cycle, including departure, transit, reception and settlement, and return or deportation. Results: A total of 47 research studies and grey literature reports were included. Most studies focused on migrants in reception and settlement (destination) settings, with only twelve sources addressing other phases of the migratory cycle. Across European countries, migrants were frequently reported to have lower uptake of routine vaccines (e.g., measles-mumps-rubella (MMR), polio, diphtheria-tetanus-pertussis (DTP), and human papillomavirus (HPV)) and COVID-19 vaccines than host populations. The most frequently reported barriers were related to migrants' legal status, administrative requirements, and lack of documentation, alongside poor affordability of vaccination, limited awareness of their rights, and mistrust in the health system. Conclusions: Health systems need to adopt innovative approaches to expand vaccine access for migrant populations. Further, protecting confidentiality is essential for building trust and reducing ethical and legal risks. Flexible and coordinated vaccination strategies are required to address migrants' mobility across the different migration stages and settings. Our findings appeal for sustained improvements in access to vaccines among migrants in Europe, contingent on strong policy commitments to equity, data protection, and the adoption of life-course and catch-up vaccination strategies.},

abstract = {T cells are crucial for defending against viral infection and cancer by eliminating infected or transformed cells and establishing immune memory. However, persistent antigenic stimulation in chronic infections or tumors drives T cells into a dysfunctional state known as exhaustion. This state is characterized by reduced proliferation and effector functions, upregulation of inhibitory receptors like PD-1, LAG-3, and CTLA-4, and alterations in transcriptional, epigenetic, and metabolic programs. T cell exhaustion is driven by both intrinsic factors, including changes in transcription factor networks and metabolic dysfunction, and extrinsic factors, such as continuous antigen exposure and an immunosuppressive microenvironment. Key molecules like PD-1, TOX, and TCF-1 are central to this process, though the complex interactions between intrinsic and extrinsic signals in chronic viral infections and cancers remain poorly understood. This review summarized T cell exhaustion in chronic viral infections, such as HIV, HBV, and SARS-CoV-2, as well as in tumors, emphasizing shared mechanisms and context-specific differences. We focused on the roles of transcriptional networks, metabolic changes, immune checkpoints, and exhaustion-related signaling. Additionally, we discussed emerging therapeutic strategies, such as immune checkpoint inhibitors, CAR-T cell therapies, cytokine supplementation, and metabolic interventions, based on recent high-impact studies. By integrating insights from both chronic infection and cancer, this review aims to identify common principles of T cell exhaustion and propose strategies to improve clinical outcomes in chronic viral diseases and cancer immunotherapy.},

abstract = {SARS-CoV-2 infection induces profound immune dysregulation, including hyperinflammation, lymphopenia, and innate/adaptive immune imbalance. In some individuals, these responses persist beyond viral clearance, creating conditions that may disrupt immunological self-tolerance and precipitate autoimmune phenomena. We critically review mechanistic and clinical evidence linking SARS-CoV-2 infection to autoimmunity. Viral entry via ACE2/TMPRSS2, endothelial injury, and renin-angiotensin system dysregulation generates a pro-inflammatory milieu. Immune pathways, including molecular mimicry, bystander activation, epitope spreading, and persistent antigenic stimulation, can trigger the activation of autoreactive lymphocytes. Emerging evidence further implicates SARS-CoV-2-associated oral-gut microbiome dysbiosis and alterations in tryptophan and arginine metabolic checkpoints as contributors to chronic inflammatory signaling and impaired tolerance maintenance. We propose a mechanistic cascade from viral infection to dysbiosis to metabolic perturbation to loss of tolerance to autoantibody generation. Clinical manifestations encompass neurological, hematological, endocrine, and systemic autoimmune syndromes, with evidence of autoantibody emergence and post-COVID-19 immune sequelae. SARS-CoV-2 acts as an amplifier of autoimmune reaction in genetically susceptible hosts. Understanding these mechanisms is critical for identifying at-risk individuals and informing preventive and therapeutic strategies for post-COVID-19 autoimmune sequelae.},

abstract = {The COVID-19 pandemic disrupted children's and adolescents' daily lives worldwide, raising concerns about changes in internalising symptoms. Prior reviews have documented elevated depression and anxiety symptoms during the pandemic, but cross-sectional designs have limited conclusions about within-person change and its moderators. To address this gap, we conducted a meta-analysis of longitudinal studies assessing internalising symptoms before and during the COVID-19 pandemic. Eighty peer-reviewed studies (187 effect sizes) contributed data from youth aged 5-17 years across 20 countries. Standardized mean change (SMC) effect sizes were synthesised using random-effects models with robust variance estimation. Guided by Bronfenbrenner's ecological systems theory, we examined moderators spanning individual, family/school, contextual, and temporal domains. Overall, internalising symptoms increased modestly from pre- to peri-pandemic assessments (SMC = 0.32, 95% CI [0.11, 0.53]; multilevel SMC = 0.34, 95% CI [0.15, 0.53]). Effects varied widely across studies (I[2] = 97.9%), indicating highly heterogeneous symptom trajectories, and suggesting that pooled estimates should be interpreted cautiously. Larger increases were observed in studies including parent-report measures and in contexts of full school closures and highly stringent government responses. Age, gender/sex, region, COVID prevalence, and assessment timing were not significant moderators. Although there were larger increases for composite scores across broad internalising and depressive symptoms than for anxiety or stress, there were no statistically robust between-domain differences. Together, these results indicate that internalising symptoms increased modestly during the COVID-19 pandemic, but that youth experiences were highly context-dependent, underscoring the importance of considering ecological conditions-such as school closures and policy responses-when evaluating pandemic-related mental health change.},

abstract = {Reactive infectious mucocutaneous eruption (RIME) is increasingly recognized as a pediatric syndrome in which severe mucositis follows a recent infection and cutaneous involvement is usually limited. Although Mycoplasma pneumoniae remains the prototype trigger, influenza, SARS-CoV-2, adenovirus, respiratory syncytial virus, and other respiratory pathogens can produce a similar clinical phenotype. This narrative review summarizes pediatric RIME/MIRM literature and selected adult or comparator-disease evidence when direct pediatric data are unavailable, explicitly distinguishing direct RIME evidence from extrapolated mechanisms. This review synthesizes current evidence on the immunopathogenesis of RIME in children, with emphasis on how pathogen-specific factors intersect with innate and adaptive immune pathways to drive mucosal injury. We discuss the central roles of epithelial sensing, inflammasome activation, cytokine amplification, neutrophil recruitment, and T-cell polarization, and we relate these mechanisms to the severe oral, ocular, and anogenital disease that often defines pediatric presentations. We also integrate emerging proteomic data showing recurring molecular programs, including acute-phase and complement activation, neutrophil-associated epithelial injury, and interferon-inducible antiviral responses. In addition, we review the possible contribution of genetic susceptibility, especially variation in innate immune sensors and cytokine signaling pathways, to disease severity and recurrence. Finally, we address the main diagnostic challenges, histopathologic and imaging findings, differential diagnosis from Stevens-Johnson syndrome, erythema multiforme, and Kawasaki disease, and the implications of these insights for risk stratification and treatment. Taken together, current evidence supports RIME as a pathogen-triggered, mucosa-predominant inflammatory syndrome in which exaggerated host responses, rather than pathogen presence alone, shape the clinical phenotype.},

abstract = {BACKGROUND: The Health Belief Model (HBM) is a widely used psychological framework for explaining and predicting individual's health related attitudes, belief, and behaviors. Although the model has been applied across various fields of health and medical sciences, the extent of its global use, particularly across African and Asian countries has not been well documented.

OBJECTIVE: This systematic review aimed to assess the application of HBM in health sciences and medical research conducted between 2010 and 2025 in Africa and Asian countries.

METHODS: The review followed the updated Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Searches were conducted using keywords "Health Belief Model" combined with Boolean operators (AND, OR) across major databases, including PubMed, CINAHL, Web of Science, Scopus, Cochrane Library and PsycINFO. Eligible studies included peer-reviewed research articles applying the HBM within African and Asian contexts.

RESULT: From a total of 1,421 identified records, 77 studies met the inclusion criteria. Of these, 61% (n = 47) were conducted in Africa countries and 39% (n = 30) in Asian countries. Most studies (64.94%) employed cross-sectional quantitative design, while 12% used mixed-methods approaches. Random controlled trial account for 9.11% of studies, quasi-experimental design for 7%, and qualitative approaches (including focus groups and in-depth interviews) for 6%. Overall, 85.71% of the studies applied all core components of HBM. Fifteen studies examined COVID-19 vaccine acceptance, nine focused on HIV/AIDS testing, counseling and prevention, and eleven studies explored non-communicable diseases prevention. Additionally, six studies assessed women's adherence to breast cancer screening, and four studies examined cervical cancer screening behaviours using HBM.

CONCLUSION: A current systematic review demonstrates that the HBM remain a valuable framework for understanding and influencing health behaviors across diverse settings. Its application in Africa and Asian research highlights its usefulness in guiding targeted interventions that address perceived susceptibility, severity, benefits, barriers, and cues to action, ultimately contributing to improved health outcomes.},

abstract = {BACKGROUND: Effective risk communication is a cornerstone of public health emergency preparedness and response. The COVID-19 pandemic and other recent crises have highlighted both the centrality of communication in sustaining trust and compliance, and the persistent gap between theoretical frameworks and operational practice.

METHODS: Within the framework of the CreSP project (Comunicare il Rischio nelle Emergenze per la Sanità Pubblica), we conducted a scoping review to map international evidence on risk communication in public health emergencies, comparing it with Italian regional pandemic preparedness plans. Following PRISMA-ScR guidelines, we searched PubMed, Scopus, and Web of Science (1 January 2019-16 May 2024). Peer-reviewed studies addressing health risk communication in emergencies were included. In parallel, 18 Italian regional pandemic plans were identified and analysed using a structured checklist derived from inductive thematic analyses.

RESULTS: Of the 12,479 records identified, 173 studies were included. Most publications originated from high-income countries and focused on COVID-19 pandemic response. Mass communication strategies, especially via social media, predominated, while targeted and participatory approaches were less frequent. The emergency response phase was far more represented than the preparedness or post-emergency phases. Key principles such as timeliness, transparency, and trust were widely discussed across studies, whereas equity, citizen engagement, and infodemic management were less consistently operationalised. Analysis of Italian regional pandemic plans revealed substantial heterogeneity. Although communication was universally acknowledged as important, it was often framed as top-down information dissemination. Structured mechanisms for monitoring, evaluation, citizen participation, and infodemic management were inconsistently addressed.

CONCLUSIONS: Although the concept of emergency risk communication is well-developed, its implementation varies across different levels of governance. The misalignment between scientific evidence and institutional frameworks-particularly regarding inclusivity, participatory models, and infodemic management-underscores the need for a more integrated and standardised national approach. Incorporating communication into preparedness infrastructures, supported by measurable indicators and workforce capacity building, is essential to strengthen resilience, equity, and public trust in the event of future emergencies.},

abstract = {Long-COVID, also referred to as post-acute sequelae of COVID-19 (PASC), is a heterogeneous disorder encompassing more than 200 reported symptoms that commonly affect the respiratory and nervous systems. Emerging clinical evidence indicates that unresolved lung inflammation, vascular injury, and immune dysregulation drive sustained neuroinflammation and impaired neurocognitive function in Long-COVID patients. Given the ethical and logistical constraints of human studies, biologically relevant animal models are essential for understanding the mechanisms and for evaluating therapeutic strategies against Long-COVID. In this review, we synthesize current evidence from preclinical animal models of Long-COVID, with a particular emphasis on the Golden Syrian Hamsters. Golden Syrian Hamsters are naturally susceptible to SARS-CoV-2 infection without the need for genetic modification and recapitulate key features of human disease, including robust viral replication, pulmonary pathology, and inflammatory response during acute infection. Importantly, accumulating evidence demonstrates that Golden Syrian Hamsters develop persistent post-acute abnormalities along the lung-brain-immune axis, including impaired alveolar repair, fibrotic lung remodeling, neuroinflammation, viral or antigen persistence, and behavioral alterations that parallel core features of Long-COVID. We compare the strengths and limitations of Golden Syrian Hamsters with other commonly used pre-clinical animal models including mice, and non-human primates, highlighting differences in translational relevance, feasibility, and ability to model chronic lung-brain-immune axis dysfunction. While there are limitations, particularly regarding limited availability of immunological reagents and validated cognitive and behavioral assays, the Golden Syrian Hamsters offers a balanced and accessible platform for mechanistic studies of PASC. Overall, this review positions Golden Syrian Hamster as a robust translational model for investigating lung-brain-immune axis pathology in Long-COVID and for advancing the development of targeted therapeutic interventions.},

abstract = {Background: Respiratory diseases (RDs), including asthma, COVID-19, chronic obstructive pulmonary disease (COPD), and pneumonia, remain a major global health challenge, contributing substantially to global morbidity and mortality. Conventional diagnosis relies heavily on clinicians' expertise to interpret respiratory sounds and radiographic images, a process that can be subjective, time-consuming, and prone to inter-observer variability. Recent advances in artificial intelligence (AI) and machine learning (ML) have enabled automated diagnostic approaches that can improve the efficiency, consistency, and scalability of respiratory disease detection. However, existing research remains fragmented across different data modalities. Methods: This review systematically analyzes recent studies on AI-based respiratory disease detection using both visual modalities (e.g., chest X-rays, computed tomography (CT) scans, and ultrasound) and audio modalities (e.g., cough and breath sounds). To provide a comprehensive perspective, the reviewed literature is organized using a unified taxonomy that categorizes existing approaches into three main groups: audio-based, visual-based, and audio-visual-based methods. In addition, two conceptual frameworks are proposed to illustrate representative pipelines for audio-based and visual-based respiratory disease classification. Results: The analysis reveals that most existing studies focus on single-modality approaches, while multimodal integration remains relatively underexplored. Only a limited number of studies combine audio and visual data within unified frameworks, primarily due to the scarcity of synchronized multimodal datasets collected from the same patients. The proposed taxonomy and conceptual frameworks provide a structured basis for comparing existing methods, identifying methodological trends, and highlighting key research gaps in multimodal respiratory disease detection. Conclusions: Future research should prioritize the development of multimodal datasets, robust evaluation protocols, and interpretable and lightweight AI models suitable for real-world clinical deployment. Advancing multimodal integration has the potential to significantly enhance the accuracy, reliability, and clinical applicability of AI-driven respiratory disease diagnosis systems.},

abstract = {The complement system is a key link between innate and adaptive immunity, contributing to pathogen elimination, immune regulation, and tissue homeostasis. Its activation is not only crucial in infections, such as COVID-19, but also plays a major role in the pathomechanism of several non-infectious respiratory diseases, such as asthma, COPD, sarcoidosis and lung cancer. Complement components can modulate the quality of the adaptive immune responses, including through the regulation of T2 immunity and eosinophilic inflammation, thereby linking natural defense to complex immune processes. In recent years, it has become increasingly clear that dysregulated complement activity contributes to inflammation, thrombosis and tissue damage in a wide range of respiratory diseases. The study of the various components of this cascade system may therefore be promising from both a diagnostic and therapeutic point of view. Some of its components may serve as biomarkers for distinguishing between different phenotypes of certain lung diseases, while their targeted inhibition or modulation may open the way towards new treatment options. A better understanding of the complement system's integrative and regulatory role not only allows for a deeper insight into immunological interactions but may also bring us closer to phenotype-oriented, immunology-based pulmonology, which may have real clinical benefits in the future.},

abstract = {Both the gut and the lungs possess a microbiome, a community of commensal bacteria, archaea, fungi, and viruses that perform important housekeeping functions in those organs. The colonic microbiome primarily ferments indigestible dietary fibers into essential short-chain fatty acids, synthesizes essential vitamins, regulates the mucosal immune system, and forms a protective barrier against pathogenic colonization. The lung microbiome maintains respiratory health primarily by regulating mucosal immunity, providing a physical barrier against invading pathogens, and producing beneficial metabolites. Several colonic microbiota metabolites, including the short-chain fatty acids acetate, propionate, and butyrate, together with the tryptophan metabolites indole-3-acetate and indole-3-propionate, secondary bile acids, and the polyamines spermidine and putrescine, are transported to the lungs via the gut-lung axis. These colonic microbiota biomolecules suppress lung inflammation, strengthen immune homeostasis, and reduce the severity of respiratory diseases. In contrast, lung microorganisms and their metabolites can travel to the gut via the gut-lung axis, influencing intestinal immune responses and potentially leading to an imbalance of gut microorganisms or dysbiosis. This means that respiratory diseases may lead to digestive issues, intestinal inflammation and chronic diseases. Here, we have reviewed this crosstalk and its impact on the principal pulmonary diseases: asthma, chronic obstructive pulmonary disease, cystic fibrosis, bronchogenic carcinoma, COVID-19, interstitial lung diseases, pneumonia, and tuberculosis. It is concluded that the gut microbiome plays a significant part in lung health and disease. Diet, tobacco smoking and electronic cigarette vaping all impact both the gut and lung microbiomes.},

abstract = {Antimicrobial resistance (AMR) is a leading global cause of death, with recent World Health Organization (WHO) data revealing that one in six laboratory-confirmed bacterial infections shows resistance to at least one antibiotic treatment. This review comprehensively analyzes the AMR landscape in 2026, detailing its evolution, mechanisms, and the innovative strategies being deployed to combat it. Driven by Darwinian selection and accelerated by factors like antibiotic overuse during the Coronavirus Disease 2019 (COVID-19) pandemic (predominantly in hospitalized patients with suspected bacterial co-infection), AMR is propelled by a diverse molecular arsenal in bacteria. Key mechanisms include enzymatic drug inactivation (e.g., the diversifying β-lactamase superfamily), target site modification (e.g., mcr genes conferring colistin resistance), efflux pumps, and biofilm formation. The rapid global spread of these traits is facilitated by a dynamic "mobilome", a network of plasmids and transposons that shuttle resistance genes between species. This crisis has sparked a major scientific mobilization. Advances include the discovery of novel antibiotic scaffolds like lariocidin and the regulatory approval of critical new antibiotic/inhibitor combinations such as sulbactam/durlobactam and aztreonam/avibactam, which target highly resistant Gram-negative bacteria. Moreover, the first-in-class antibiotic gepotidacin offers a new option for urinary tract infections. Beyond traditional drugs, the pipeline is diversifying to include phage therapy, antivirulence strategies, and artificial intelligence-guided drug discovery. This diversification is critical as it helps preserve the effectiveness of existing Medically Important Antimicrobials (MIAs), those deemed essential for human medicine, by providing alternative or adjunctive treatment options. However, scientific innovation alone is insufficient. This review argues that lasting success requires parallel progress in global policy and infrastructure. Strategic priorities beyond 2026 must include finalizing and funding updated global action plans, strengthening real-time surveillance and diagnostic capacity, especially in low-resource settings, and implementing new economic models to de-risk antibiotic development. Embedding effective antimicrobial stewardship within universal health coverage and pandemic preparedness plans is crucial. Ultimately, defeating AMR demands an unprecedented, coordinated global effort that outpaces the relentless adaptability of bacterial pathogens.},

abstract = {The immune response is essential in the protection of our body against pathogens; however, the inflammatory response caused by the immune system can become a disease itself. In fact, anti-inflammatory and immune-suppressive drugs are applied to limit the immune response to treat inflammatory diseases. Flavonoids are plant-derived polyphenols extensively investigated for their anti-inflammatory and antioxidant properties in inflammatory diseases. Studies applying isolated compounds as well as using supplements as nutraceuticals based on flavonoids have been conducted. Our review systematically analyzed the top five studied flavonoids between 2020 and 2025: quercetin (1742 articles), kaempferol (642), luteolin (589), apigenin (419), and epicatechin (354), highlighting their major therapeutic applications in diseases affecting the liver (12%), nervous system (11%), and lungs (10%). Mechanistically, these compounds act as multi-target agents mainly by inhibiting NF-κB and inducing Nrf2-dependent antioxidant programs. Application of advanced delivery systems, which increase oral bioavailability by up to 20-fold, overcomes pharmacokinetic bottlenecks. Clinical highlights demonstrated promising therapeutic effects, including reduced intrahepatic lipid accumulation in non-alcoholic fatty liver disease patients following quercetin supplementation (11.5% to 9.6%) and accelerated SARS-CoV-2 clearance after quercetin phytosome administration. The translation of flavonoids into standardized clinical therapies remains limited by the lack of large-scale, well-controlled clinical trials.},

abstract = {Background: Increasing evidence suggests that COVID-19 can induce or exacerbate autoimmune disorders, including immune-mediated thyroid dysfunction. The most common autoimmune thyroid diseases are Graves' disease and Hashimoto's thyroiditis; the mechanisms by which viral infections like SARS-CoV-2 trigger these diseases are not fully understood. Objectives: This study aims to systematically review published clinical evidence on the presentation, laboratory characteristics, and outcomes of autoimmune thyroid diseases after COVID-19 infection. Methods: The review followed the PRISMA 2020 framework. Scopus, Web of Science, and PubMed were searched for English-language studies between January 2020 and December 2025 using the terms COVID-19, SARS-CoV-2, autoimmune thyroiditis, Graves' disease, Hashimoto's thyroiditis, and autoimmune thyroid disease. Results: In total, 46 studies (five cohort studies and 41 case reports/series) involving 3856 patients were analyzed. The findings indicate that a significant increase in TPOAb prevalence occurs post-COVID-19 infection (15.7% vs. 7.7% in controls). New-onset Graves' disease (GD) post-COVID-19 presented with higher fT3/fT4 ratios and more aggressive thyrotoxicosis compared to non-viral cases. Rare but severe manifestations included thyrotoxic periodic paralysis, Hashimoto's encephalopathy, and dilated cardiomyopathy. Conclusions: SARS-CoV-2 may act as a trigger for autoimmune thyroid diseases, particularly in moderate-to-severe infections; however, the strength of this association warrants further investigation with controlled prospective data. Standard therapy remains effective, but thyroid function monitoring is advisable during post-COVID-19 recovery. An interdisciplinary approach is essential for early diagnosis and management of systemic complications.},

abstract = {Post-acute sequelae of SARS-CoV-2 infection (PASC) extend well beyond the acute respiratory phase, with accumulating virological evidence that SARS-CoV-2 RNA, viral antigens, and proteolytic fragments may persist in cardiovascular and other extrapulmonary tissues, although the extent to which such detection represents replication-competent reservoirs versus residual viral material with uncertain pathological relevance remains under active investigation. Sudden cardiac death (SCD) and fatal pulmonary thromboembolism (PTE) have emerged as forensically and epidemiologically significant outcomes in individuals with prior infection, situated at the intersection of microbiology, public health, and forensic medicine. To synthesize current evidence on the virological mechanisms by which SARS-CoV-2 may contribute to post-acute sudden cardiac death (SCD) and pulmonary thromboembolism (PTE), the population-level epidemiology of these outcomes, and their implications for public health surveillance and forensic practice, we conducted a narrative review of PubMed (MEDLINE), Scopus, and Web of Science Core Collection. The search covered publications from January 2020 to December 2025 and focused on SARS-CoV-2 cellular tropism and tissue persistence, immune-mediated and thromboinflammatory mechanisms, excess cardiovascular and thromboembolic mortality, and autopsy-based pathological findings. After de-duplication of 1837 initially identified records (412 duplicates removed) and screening of 1425 unique records, 78 studies were retained for final synthesis based on virological, epidemiological, and forensic relevance. SARS-CoV-2 enters cardiomyocytes, pericytes, and vascular endothelial cells through ACE2-dependent mechanisms, with cathepsin L compensating for the limited cardiac expression of TMPRSS2. Viral RNA and antigen have been detected in cardiovascular and other extrapulmonary tissues months after symptom onset in selected autopsy series, although persistent detection of viral components does not necessarily indicate ongoing productive infection or direct tissue injury. Endothelial dysfunction, neutrophil extracellular trap (NET) formation, complement activation, and persistent thromboinflammation have been proposed as plausible mechanistic substrates for arrhythmogenic remodelling and thromboembolic events, although definitive causal pathways remain incompletely understood. Population-based studies document persistent excess cardiovascular mortality across multiple jurisdictions, with hazard ratios for pulmonary embolism remaining elevated months after acute infection, particularly in unvaccinated individuals. Autopsy series identify mixed pathological patterns including focal lymphocytic infiltrates, microvascular thrombosis, contraction-band necrosis, and cardiomyocyte vacuolation, although fulminant lymphocytic myocarditis fulfilling Dallas criteria remains uncommon. A microbiology-informed framework uniting tissue-based viral detection, standardized cardiac and pulmonary sampling protocols, and prospective post-mortem registries is needed to better characterize the potential contribution of SARS-CoV-2 to post-acute cardiovascular mortality and to support cause-of-death certification, public health surveillance, and medicolegal practice in the post-pandemic era. Many of the proposed mechanisms remain under active investigation, and definitive causal relationships between viral persistence and adverse cardiovascular outcomes have not yet been conclusively established.},

Pathogen transformation depends on host traits, contact frequency, and viral characteristics. Anthropogenic drivers-including livestock expansion, the bushmeat trade, wet markets, and the exotic pet industry-significantly elevate spillover risks.
