abstract = {The Global Initiative for Asthma (GINA) was established in 1993 by the World Health Organization and the US National Heart Lung and Blood Institute to improve asthma awareness, prevention and management worldwide. GINA develops and publishes evidence-based, annually updated resources for clinicians. GINA guidance is adopted by national asthma guidelines in many countries, adapted to fit local healthcare systems, practices, and resource availability. GINA is independent of industry, funded by the sale and licensing of its materials. This review summarizes key practical guidance for primary care from the 2022 GINA strategy report. It provides guidance on confirming the diagnosis of asthma using spirometry or peak expiratory flow. GINA recommends that all adults, adolescents and most children with asthma should receive inhaled corticosteroid (ICS)-containing therapy to reduce the risk of severe exacerbations, either taken regularly, or (for adults and adolescents with "mild" asthma) as combination ICS-formoterol taken as needed for symptom relief. For patients with moderate-severe asthma, the preferred regimen is maintenance-and-reliever therapy (MART) with ICS-formoterol. Asthma treatment is not "one size fits all"; GINA recommends individualized assessment, adjustment, and review of treatment. As many patients with difficult-to-treat or severe asthma are not referred early for specialist review, we provide updated guidance for primary care on diagnosis, further investigation, optimization and treatment of severe asthma across secondary and tertiary care. While the GINA strategy has global relevance, we recognize that there are special considerations for its adoption in low- and middle-income countries, particularly the current poor access to inhaled medications.},

abstract = {Achieving durable antibody-mediated protection remains critical in vaccine development, particularly for viral diseases like COVID-19 and HIV. We discuss factors influencing antibody durability, highlighting the role of long-lived plasma cells (LLPCs) in the bone marrow, which are essential for sustained antibody production over many years. The frequencies and properties of bone marrow LLPC are critical determinants of the broad spectrum of antibody durability for different vaccines. Vaccines for diseases like measles and mumps elicit long-lasting antibodies; those for COVID-19 and HIV do not. High epitope densities in the vaccine are known to favor antibody durability, but we discuss three underappreciated variables that also play a role in long-lived antibody responses. First, in addition to high epitope densities, we discuss the importance of CD21 as a critical determinant of antibody durability. CD21 is a B cell antigen receptor (BCR) complex component. It significantly affects BCR signaling strength in a way essential for generating LLPC in the bone marrow. Second, all antibody-secreting cells (ASC) are not created equal. There is a four-log range of antibody secretion rates, and we propose epigenetic imprinting of different rates on ASC, including LLPC, as a factor in antibody durability. Third, antibody durability afforded by bone marrow LLPC is independent of continuous antigenic stimulation. By contrast, tissue-resident T-bet+CD21low ASC also persists in secondary lymphoid tissues and continuously produces antibodies depending on persisting antigen and the tissue microenvironment. We discuss these variables in the context of making an HIV vaccine that elicits broadly neutralizing antibodies against HIV that persist at protective levels without continuous vaccination over many years.},

abstract = {Fragment-based drug discovery (FBDD) has emerged as a transformative strategy in modern medicinal chemistry, offering a rational and efficient alternative to traditional highthroughput screening (HTS). By utilizing small, low-molecular-weight fragments with moderate binding affinity, FBDD enables systematic optimization into potent lead compounds with improved physicochemical properties. Its modular and ligand-centric nature has proven particularly advantageous in accelerating early-stage drug discovery. The COVID-19 pandemic highlighted the adaptability of FBDD, as fragment screening and computational modeling rapidly identified inhibitors of the SARS-CoV-2 main protease (M[pro]). Integration with artificial intelligence (AI) and cloud-based platforms further enhanced the speed and global accessibility of fragment campaigns, setting a precedent for collaborative, open-science initiatives. Beyond infectious diseases, FBDD has demonstrated significant promise in oncology, antibacterial therapy, and neurodegenerative disorders, reflecting its versatility across diverse therapeutic landscapes. Recent technological advances have expanded the scope of FBDD. High-resolution cryo-electron microscopy and AI-driven structural prediction now enable the exploration of previously inaccessible or dynamic protein targets. Emerging modalities, such as PROTACs and RNA-targeted therapeutics, also intersect with fragment-based strategies, opening avenues for addressing so-called "undruggable" proteins. Despite persistent challenges, including the need for sensitive biophysical methods and sophisticated infrastructure, the approach continues to evolve. Looking ahead, the convergence of FBDD with machine learning, open-access fragment libraries, and global research collaboration positions it as a scalable, adaptive platform for drug discovery. As future health threats demand rapid innovation, FBDD is poised to remain a cornerstone of both academic and industrial research pipelines.},

abstract = {There is an urgent need to develop effective antiviral treatments against SARS-CoV-2. Despite the availability of vaccines, drug discovery remains critical for combating emerging variants. Molecular docking studies have become a vital computational tool for identifying antiviral drugs capable of inhibiting different SARS-CoV-2 proteins. This review explores the role of metal complexes as promising viral inhibitors through in silico molecular docking approaches. The binding abilities of several coordination complexes derived from iron, copper, palladium, and zinc ions have been evaluated against major viral proteins such as the spike glycoprotein, RNA-dependent RNA polymerase (RdRp), and the main protease (Mpro), which are responsible for viral infection. Comparative docking studies of specific metal-based compounds with conventional antiviral drugs highlight their superior binding affinities and inhibitory potential. Furthermore, ADME (Absorption, Distribution, Metabolism, and Excretion) analyses, molecular dynamics simulations, and drugdelivery strategies are discussed to assess pharmacokinetics and therapeutic viability. Overall, this review emphasizes the importance of molecular docking in the rational design of metal complexes as antiviral agents and its relevance for developing effective therapeutic strategies to combat COVID-19.},

abstract = {Alopecia is a prevalent condition that affects both sexes, characterised by miniaturisation of hair follicles and changes in the dynamics of the hair cycle, such as androgenetic alopecia associated with various systemic factors, including the COVID-19 pandemic. Minoxidil (base), initially developed as an oral antihypertensive, is currently used in the treatment of alopecia, acting as a prodrug that requires hepatic sulphation to generate its active metabolite, minoxidil sulphate. Topical formulations use minoxidil sulphate, the active pharmaceutical ingredient, directly on the hair follicles. Pharmacogenomic studies highlight the critical role of SULT1A1 enzyme variability in modulating treatment response, supporting personalised therapeutic strategies. Despite challenges related to low water solubility, high permeability, and narrow therapeutic index, emerging pharmaceutical technologies, including minitablets, orodispersible forms, sublingual preparations, and modified release systems, offer the potential to optimise absorption, increase dosing accuracy, and reduce adverse effects. This review consolidates current knowledge on the chemistry, pharmacology, pharmacogenomics, and technological aspects of minoxidil (base) for systemic use, emphasising translational developments that may redefine its clinical applications and contribute to safer and more standardised therapies. The integration of medicinal chemistry, pharmaceutical technology, clinical pharmacology, and regulatory guidance is expected to promote oral minoxidil as a reliable, effective, and patient-centred therapeutic option for alopecia.},

abstract = {BACKGROUND: Nursing homes were severely affected by the COVID-19 pandemic. Standardised parameters are essential to understand and monitor the unintended consequences of pandemic control measures and changes in work processes. In this scoping review, we aimed to identify COVID-19-related parameters studied in nursing homes that could form a minimum data set suitable for database development. We focused on the perspectives of all interest-holders: facilities, residents, their relatives and nursing home staff.

METHODS: We searched MEDLINE and CINAHL and included quantitative studies published in English since the beginning of the pandemic (2020 to 2024). The extracted parameters were initially categorised according to five dimensions: pandemic-related data, facility level, staff level, residents and relatives. Within each dimension, the original terms were compared and inductively organised into (sub-)categories based on conceptual similarities, with synonymous terms subsequently standardised.

RESULTS: From 82 included articles, 96 different parameters related to COVID-19 in nursing homes were identified. Infection and mortality rates emerged as the pandemic-related data most often reported, particularly within this dimension but also across all dimensions. However, we found a broad range of resident-related parameters. Our most often identified facility-related parameters include the number of staff and the provision of personal protective equipment. Staff-related parameters most often studied were personal burden and stress. Only a few parameters (n = 9) were considered for relatives.

CONCLUSIONS: The diversity of the reported parameters indicates that a comprehensive database is required to adequately assess a pandemic situation in this vulnerable population. In terms of pandemic preparedness, our overview of the reported parameters offers a basis for the development of country- and context-specific data capture approaches.},

abstract = {The rapid global spread of SARS-CoV-2 triggered an unprecedented effort to develop effective antivirals. Among the first approved agents was remdesivir, an injectable nucleoside analogue developed by Gilead Sciences, that led to chain termination of viral RNA synthesis and showed broad antiviral activity against RNA viruses. Early clinical results were mixed: The US ACTT-1 trial reported an accelerated recovery and reduced mortality in treated patients, while the WHO Solidarity and a European trial revealed no impact of remdesivir on mortality. In contrast, a US trial in outpatients demonstrated a clear clinical benefit when treatment was administered early. Molnupiravir, an orally applicable nucleoside analogue developed by Merck, induces lethal mutations in the viral genome rather than chain termination. Molnupiravir showed in vivo antiviral activity against coronaviruses in different animals. In MOVe-OUT trials, molnupiravir reduced the rate of hospitalisation in treated outpatients. In the PANORAMIC trial, molnupiravir reduced the time to recovery in outpatients but not their rate of hospitalisation. No drug effect of molnupiravir was seen in the RECOVERY trial with hospitalised COVID-19 patients. Using structural biology and medicinal chemistry approaches, Pfizer developed nirmatrelvir, an oral inhibitor of the major coronavirus protease. In high-risk but not in standard-risk COVID-19 patients, the combination nirmatrelvir/ritonavir reduced the rate of hospitalisation (EPIC HR and SR trials). Retrospective cohort studies showed treatment effects in defined patient groups. This review compares the efficacy and clinical performance of different antivirals, including emerging drugs such as obeldesivir and alternative protease inhibitors (lopinavir, simnotrelvir). It further examines their roles in prophylaxis, treatment of long covid symptoms, pharmacological considerations and antiviral resistance. Particular attention is given to factors underlying variable outcome of the trials, including viral variant evolution, population immunity increases, disease severity changes and timing of therapy initiation.},

Unfortunately, clinical studies have generated mixed results. This gap between laboratory findings and real-world outcomes highlights the need for high-quality research in the field. Another promising domain is the utilization of vitamin D analogs that can provide similar or even better benefits than native vitamin D, but with fewer side effects. Additionally, the standardization of vitamin D measurement from biologic samples in clinical and research laboratories must be improved to successfully manage individual patients and clinical research. All these aspects are dealt with in detail in this chapter.},

We report a case of severe GPP triggered by SARS-CoV-2 infection in a 46-year-old woman with a long history of psoriasis. Eleven days after recovery from COVID-19 pneumonia, she developed widespread pustules and fever. Histopathology revealed subcorneal spongiform pustules and dermal neutrophilic infiltration consistent with GPP. Systemic corticosteroids followed by etretinate and deucravacitinib achieved complete remission. A literature review identified 11 infection- and 10 vaccine-related GPP cases. Compared with vaccine-associated cases, infection-related flares showed longer latency and higher corticosteroid use. Mechanistically, both SARS-CoV-2 infection and vaccination may be associated with IL-36 axis activation, potentially via spike protein-driven, Toll-like receptor-mediated innate immune signaling. This case highlights that distinct immune kinetics may underlie infection- and vaccine-related GPP, while supporting a putative role of IL-36-driven inflammation in COVID-19-associated disease exacerbation.},

The effectiveness of non-pharmacological rehabilitation in this severity-specific subgroup remains uncertain.MethodsA systematic review was conducted in accordance with PRISMA 2020 guidelines. PubMed, Epistemonikos, LILACS, and Google Scholar were searched for randomized and observational studies evaluating non-pharmacological rehabilitation in adult ICU survivors of COVID-19. Risk of bias was assessed using RoB 2 and ROBINS-I tools. Given substantial clinical and methodological heterogeneity, quantitative meta-analysis was not performed; a structured narrative synthesis was undertaken.ResultsFourteen studies met inclusion criteria. Five incorporated comparator groups, while nine employed uncontrolled pre-post designs. Interventions ranged from early ICU mobilization to inpatient and outpatient pulmonary rehabilitation. Controlled studies reported variable between-group benefits in dyspnea and functional outcomes, whereas observational studies consistently described within-group improvement over time. However, most studies were at moderate to serious risk of bias, and heterogeneity in intervention timing, dosage, and outcome assessment limited comparability.ConclusionsNon-pharmacological rehabilitation in ICU survivors of COVID-19 is associated with improvement over time; however, the certainty of causal effectiveness remains low. ICU survivors constitute a distinct recovery population within the broader post-COVID spectrum. Adequately powered, multicenter randomized trials with standardized protocols and harmonized outcomes are required to establish long-term effectiveness.},

abstract = {BACKGROUND AND AIMS: Labor pain is a multidimensional experience influenced by emotional, cognitive, and cultural factors. It can be managed using pharmacological, non-pharmacological, or combined approaches. Licensed obstetric care providers (OCPs) are ethically obligated to ensure maternal comfort while safeguarding fetal safety. Evidence on labor pain management practices (LPMP) in Ethiopia remains inconsistent, as prior studies often included students or had unclear inclusion criteria. This systematic review and meta-analysis estimated the pooled prevalence of LPMP among licensed OCPs, identified associated factors, and examined trends before and during the COVID-19 pandemic.

METHODS: We searched major databases and repositories for studies published between January 1, 2018 and October 3, 2025. Risk of bias was assessed using the Joanna Briggs Institute checklist and modified Newcastle-Ottawa Scale, with inter-rater reliability analyses. Meta-analysis was conducted in STATA 17 using random or fixed-effects models. Heterogeneity was assessed using Cochran's Q test and quantified with I[2] statistic. Certainty of evidence rated using GRADE.

RESULTS: Twenty studies involving 7,202 participants were included. LPMP prevalence varied substantially across studies and settings. The pooled prevalence of overall LPMP was 46.9% (95% CI: 42.7-51.1; I[2] = 92.4%). Non-pharmacological practice was 42.8% (95% CI: 36.6-49.1), whereas pharmacological practice was 21.1% (95% CI: 12.5-29.7), decreasing to 15.2% after adjustment for publication bias. Pharmacological practice was modestly higher during COVID-19 (23.7% vs. 18.0%). Factors positively associated with LPMP included provider knowledge, attitudes, training, drug/protocol availability, supportive environments, higher education, longer experience, positive perceptions, being a midwife, and female sex. Certainty of evidence ranged from low to moderate.

CONCLUSION: LPMP prevalence varied considerably across studies and settings. While the pooled estimate suggests that fewer than half of Ethiopian OCPs practiced LPMP, substantial unexplained heterogeneity warrants cautious interpretation. Non-pharmacological methods were more commonly used than pharmacological approaches, highlighting opportunities to strengthen provider training, institutional support, and resource availability.},

abstract = {Tuberculosis (TB) remains a major global public health challenge and one of the leading infectious causes of mortality worldwide, with India contributing approximately 26% of the global TB burden. Despite substantial progress under the National Tuberculosis Elimination Programme (NTEP), India's efforts to achieve the ambitious 2025 TB elimination target continue to face major challenges due to the COVID-19 pandemic, multidrug-resistant tuberculosis (MDR-TB), healthcare disparities, and limitations in surveillance and reporting systems. This review provides a comprehensive overview of the epidemiology of TB in India and critically evaluates the impact of COVID-19, drug resistance, healthcare accessibility, and emerging diagnostic technologies on TB control efforts. A structured literature search was conducted using PubMed, Scopus, and Google Scholar, along with reports from the World Health Organization and the Government of India. The reviewed evidence indicates that the COVID-19 pandemic significantly disrupted TB diagnosis, treatment, surveillance, and healthcare accessibility, leading to declines in case notification and the possible accumulation of undiagnosed TB cases. In addition, the increasing burden of MDR/RR-TB, fragmented private healthcare systems, underreporting, and unequal access to diagnostics and treatment continue to hinder progress toward TB elimination. Although advancements including molecular diagnostics, digital surveillance platforms such as Nikshay, AI-assisted screening, and patient-support programmes have strengthened TB control strategies, important challenges related to implementation, infrastructure, scalability, and antimicrobial stewardship remain unresolved. This review highlights the need for integrated and patient-centred TB control strategies that combine rapid diagnostics, strengthened surveillance, public-private healthcare integration, health systems strengthening, and interventions addressing broader socioeconomic determinants such as poverty, malnutrition, and healthcare inequity. Coordinated multisectoral approaches will be essential for accelerating TB elimination efforts in India in the post-COVID era.},

abstract = {BACKGROUND: Critically ill patients are frequently deficient in vitamin C. Given the significant mortality rates in the elderly population associated with COVID-19, we aimed to systematically review the literature and evaluate whether high-dose vitamin C can reduce COVID-19 mortality in this population.

METHODS: Multiple data sources (PubMed, Web of Science, ScienceDirect, and medRxiv) were searched using the keywords "COVID-19" AND "vitamin C" up to November 2024. Randomized controlled trials (RCTs) involving COVID-19 patients with relevant data were collected. We used a random or fixed effects meta-analysis to calculate the pooling effect.

RESULTS: Eight RCTs comprising 2,104 patients were ultimately included in the meta-analysis. The pooling effect (odds ratio [OR] 0.97[95% CI 0.80-1.18, P = 0.76) suggested no significant difference in mortality rates between patients treated with high-dose vitamin C and those who were not.

CONCLUSIONS: Vitamin C supplementation might reduce the risk of COVID-19 mortality in critically ill patients; however, this effect varied by study. Additional research is necessary to arrive at a definitive conclusion on this subject.},

abstract = {Respiratory infections caused by viral pathogens, including influenza A virus, respiratory syncytial virus, and SARS-CoV-2, as well as bacterial pathogens, remain major contributors to global morbidity and mortality. The outcomes of these infections are largely determined by how the host innate immune system detects pathogen-derived nucleic acids and regulates subsequent inflammatory responses. Pattern recognition receptors (PRRs) located in endosomal and cytosolic compartments, including Toll-like receptors, RIG-I-like receptors, absent in melanoma 2, and Z-DNA-binding protein 1, as well as the cyclic GMP-AMP synthase-stimulator of interferon genes pathway, recognize viral and bacterial nucleic acids and initiate signaling cascades that promote cytokine production and antimicrobial defense. However, dysregulated PRR activation can trigger inflammatory programmed cell death, including apoptosis, pyroptosis, necroptosis, and PANoptosis. This review summarizes recent advances in understanding how nucleic acid sensing orchestrates inflammatory cell death during respiratory infections, with particular emphasis on pathogen- and cell type-specific mechanisms that shape disease outcomes. We further highlight the dual nature of these pathways, which are essential for pathogen clearance but can drive immunopathology when excessively activated. Defining how nucleic acid-sensing pathways shape inflammatory cell death in respiratory infections may guide host-directed therapies that enhance pathogen clearance while preserving lung function. Overall, the field remains constrained by the predominance of virus-focused and murine preclinical studies, whereas bacterial nucleic acid sensing during respiratory infections remains poorly defined. Future studies should integrate major bacterial infection models with human-relevant respiratory epithelial systems to better translate PRR-mediated immune mechanisms into host-directed therapeutic strategies.},

abstract = {BACKGROUND: Mass outbreaks such as pandemics are associated with mental health problems requiring effective psychological interventions. Although several forms of psychological interventions may be advocated or used, some may lack strong evidence of efficacy and some may not have been evaluated in mass infectious disease outbreaks. This paper reports a systematic review of published studies (PROSPERO CRD:42020182094. Registered: 24.04.2020) examining the types and effectiveness of psychological support interventions for the general population and healthcare workers exposed to mass infectious disease outbreaks.

METHODS: A systematic review was conducted. Randomised Controlled Trials (RCT) were identified through searches of electronic databases: Medline (Ovid), Embase (Ovid), PsycINFO (EBSCO) and the Cochrane Library Database from inception to 06.05.2021 using an agreed search strategy. Studies were included if they assessed the effectiveness of interventions providing psychological support to the general population and / or healthcare workers exposed to mass infectious disease outbreaks. Studies were excluded if they focused on man-made or natural disasters or if they included armed forces, police, fire-fighters or coastguards.

RESULTS: Twenty-two RCTs were included after screening. Various psychological interventions have been used: therapist-guided therapy (n = 1); online counselling (n = 1); 'Emotional Freedom Techniques' (n = 1); mobile phone apps (n = 2); brief crisis intervention (n = 1); psychological-behavioural intervention (n = 1); Cognitive Behavioural Therapy (n = 3); progressive muscle relaxation (n = 2); emotional-based directed drawing (n = 1); psycho-educational debriefing (n = 1); guided imagery (n = 1); Eye Movement Desensitization and Reprocessing (EMDR) (n = 1); expressive writing (n = 2); tailored intervention for patients with a chronic medical conditions (n = 1); community health workers (n = 1); self-guided psychological intervention (n = 1), and a digital behaviour change intervention (n = 1). Meta-analyses showed that psychological interventions had a statistically significant benefit in managing depression (Standardised Mean Difference [SMD]: -0.40; 95% Confidence Interval [CI]: - 0.76 to - 0.03), and anxiety (SMD: -0.72; 95% CI: - 1.03 to - 0.40). The effect on stress was equivocal (SMD: 0.16; 95% CI: - 0.19 to 0.51). The heterogeneity of studies, studies' high risk of bias, and the lack of available evidence means uncertainty remains.

CONCLUSIONS: Further RCTs and intervention studies involving representative study populations are needed to inform the development of targeted and tailored psychological interventions for those exposed to mass infectious disease outbreaks.},

abstract = {PURPOSE OF REVIEW: Neuroinflammation plays a significant role in Parkinson's disease (PD) etiology along with mitochondrial dysfunction and impaired proteostasis. In this context, mechanisms related to immune response can act as modifiers at different steps of the neurodegenerative process and justify the growing interest in anti-inflammatory agents as potential disease-modifying treatments in PD. The discovery of inherited gene mutations in PD has allowed researchers to develop cellular and animal models to study the mechanisms of the underlying biology, but the original cause of neuroinflammation in PD is still debated to date.

RECENT FINDINGS: Cell autonomous alterations in neuronal cells, including mitochondrial damage and protein aggregation, could play a role, but recent findings also highlighted the importance of intercellular communication at both local and systemic level. This has given rise to debate about the role of non-neuronal cells in PD and reignited intense research into the gut-brain axis and other non-neuronal interactions in the development of the disease. Whatever the original trigger of neuroinflammation in PD, what appears quite clear is that the aberrant activation of glial cells and other components of the immune system creates a vicious circle in which neurodegeneration and neuroinflammation nourish each other. In this review, we will provide an up-to-date summary of the main cellular alterations underlying neuroinflammation in PD, including those induced by environmental factors (e.g. the gut microbiome) and those related to the genetic background of affected patients. Starting from the lesson provided by familial forms of PD, we will discuss pathophysiological mechanisms linked to inflammation that could also play a role in idiopathic forms. Finally, we will comment on the potential clinical translatability of immunobiomarkers identified in PD patient cohorts and provide an update on current therapeutic strategies aimed at overcoming or preventing inflammation in PD.},

abstract = {UNLABELLED: Iron deficiency is the primary cause of anaemia worldwide and is particularly common among children and adolescents. Intravenous (IV) iron therapy is recommended for paediatric patients with certain comorbidities or if oral iron treatment has been unsuccessful. IV ferric carboxymaltose (FCM) has recently been approved by the US Food and Drug Administration for use in children aged > 1 year. This narrative review provides an overview of the available publications on the efficacy and safety of IV FCM in children and adolescents. A literature search using PubMed and Embase yielded 153 publications; 33 contained clinical data or reports on clinical experience relating to IV FCM in subjects < 18 years of age and were included in the review. No prospective, randomised controlled studies on the topic were found. Most publications were retrospective studies or case reports and included patients with various underlying conditions or patients with inflammatory bowel disease. Efficacy data were included in 27/33 publications and improvements in anaemia, and/or iron status parameters were reported in 26 of them. Safety data were included in 25/33 publications and were in line with the adverse events described in the prescribing information.

CONCLUSION: The available publications indicate that IV FCM, a nanomedicine with a unique and distinctive therapeutic profile, is an effective and generally well-tolerated treatment for iron deficiency or iron deficiency anaemia in children and adolescents. Despite the wealth of retrospective evidence, prospective, randomised controlled trials in the paediatric setting are still necessary.

WHAT IS KNOWN: • Iron deficiency and iron deficiency anaemia are usually managed using oral iron therapy, but intravenous iron therapy is recommended for certain paediatric patients. • Intravenous ferric carboxymaltose (FCM) has recently been approved in the US for use in children aged > 1 year.

WHAT IS NEW: • Despite evidence that FCM is effective and generally well tolerated in children and adolescents, so far, only retrospective studies, non-randomised uncontrolled prospective studies, or case reports have been published in full. • There is a strong need for prospective, randomised controlled trials on FCM in the paediatric setting.},

This is not the case for adverse effects, which are influenced by the drug characteristics and the population receiving the treatment. In this context, can we truly balance the benefits and risks of medications? The experience of Covid-19 illustrates the complexity of this concept. It clearly highlights the need for a comprehensive approach, integrating analysis of clinical trials, pharmacovigilance monitoring, pharmacoepidemiology studies, and the detection of potential drug interactions. Finally, it is essential to inform and educate the general public about medications. This empowers individuals to accurately understand the complex concept of benefit-risk balance, prevents misleading over simplifications, and helps effectively counter misinformation.},

abstract = {OBJECTIVES: To develop a practical consensus-based framework for 10 steps to improve sepsis care in low-resource settings (LRSs), aligned with the sepsis chain of survival and informed by global expertise.

DATA SOURCES: We reviewed peer-reviewed literature on sepsis epidemiology, prevention, recognition, and management in LRS; international guidelines, including the Surviving Sepsis Campaign; and prior "10-step" consensus frameworks for resuscitation and emergency care.

STUDY SELECTION: A Task Force representing adult and pediatric sepsis care, emergency care, critical care, infectious diseases, public health, and implementation science identified key domains from the above data sources.

DATA EXTRACTION: With guidance from methodologists and implementation science experts, we utilized an iterative, consensus-based process-literature review, Delphi survey, Utstein-style conference, stakeholder input, and public comment-to first define and then refine steps and implementation strategies.

DATA SYNTHESIS: The process resulted in 10 nonsequential, actionable steps covering governance and commodities, provider and caregiver education, community and facility prevention, early recognition and rapid response, timely guideline-based interventions, structured post-sepsis care, data systems, quality improvement, a culture of excellence and respect, and holistic well-being of patients, caregivers, and providers. Each step includes a rationale and potential implementation strategies adaptable to local resources and needs. Collectively, the ten steps emphasize integration across the continuum of care, equitable access to essential interventions, and the role of emerging technologies to prevent, recognize, monitor, and follow-up sepsis.

CONCLUSIONS: The 10 steps provide a consensus-driven roadmap for health leaders, clinicians, and policymakers to improve sepsis care, strengthen the sepsis chain of survival, reduce preventable morbidity and mortality, and address global inequities in sepsis outcomes.},

STUDY SELECTION: Studies selected included human studies (clinical trials, cohort, case-control, and case series) reporting clinical outcomes in patients with sepsis from LRS between January 1, 2000, and July 4, 2024. Search terms included "developing countries," "LMIC," "resource-poor settings," and regional terms such as Africa, Southeast Asia, and Latin America. The Delphi process involved iterative, anonymous voting by the expert panel to achieve consensus to draft clinical practice statements.

DATA EXTRACTION: A detailed literature review was conducted using the "sepsis chain of survival" as a basis, with an emphasis on sepsis prevention, detection, therapy, post-sepsis care, education, and future research priorities. A total of 8865 studies were identified and screened, with 155 included in the review.

DATA SYNTHESIS: Based on literature review, the Delphi process achieved a stable consensus for 58 of 62 (94%) of the proposed clinical practice statements after eight survey rounds. These statements offer guidance on measures to improve the prevention, early recognition and time-sensitive, comprehensive management of sepsis in LRS through the continuum of care from first response to post-sepsis care and follow-up.

CONCLUSIONS: There remains a significant lack of high-quality evidence to support improvements in sepsis care for patients in LRS. Pending new data, the clinical practice statements identified here complement the existing international guidelines for sepsis management by serving as a basis for immediate care and future research in LRS.},

abstract = {OBJECTIVES: Sepsis is a time-sensitive cause of preventable death worldwide, with disproportionate mortality in low-resource settings (LRS). Many recommendations in international sepsis guidance presume resources unavailable in many facilities and communities. We sought to develop a practical framework that helps health systems embed feasible sepsis actions within broader emergency and essential critical care systems, while highlighting where evidence is limited and where local learning systems are needed.

DATA SOURCES: A targeted scoping review of peer-reviewed and grey literature on sepsis epidemiology, emergency care systems, essential emergency and critical care, implementation strategies, and quality improvement (QI) in LRS; and key guideline and policy documents relevant to sepsis and emergency care.

STUDY SELECTION: We prioritized publications and guidance relevant to LRS, including observational studies, pragmatic implementation reports, consensus statements, and policies addressing emergency care organization, workforce, supply chains, diagnostics, and QI.

DATA EXTRACTION: Task force members abstracted actionable strategies, implementation barriers/enablers, and feasibility considerations across the care continuum (community, transport/prehospital, facility-based acute care, and referral). We also identified domains where guideline certainty is low or indirect for LRS.

DATA SYNTHESIS: A Society of Critical Care Medicine-convened multidisciplinary task force iteratively developed the "Sepsis Frame of Survival" using a structured process that included 1) scoping evidence review, 2) a Delphi-style prioritization of candidate framework elements by importance and feasibility, and 3) a structured consensus meeting ("Utstein-style" conference format) to finalize the model and its priority actions. We produced a concise implementation roadmap and a feasible measurement set aligned with resource constraints.

CONCLUSIONS: The Sepsis Frame of Survival is a pragmatic model to organize sepsis improvement as part of emergency and essential critical care strengthening. It emphasizes high-impact actions that can be implemented with limited resources (triage and early recognition, timely antimicrobials, oxygen and basic supportive care, cautious fluid resuscitation with reassessment, source control and referral, diagnostics/microbiology where feasible, and QI). The framework explicitly distinguishes near-term, feasible changes from longer-term system investments and highlights the need for locally generated evidence to guide quality indicators and resuscitation strategies in LRS.},

Intensive research activities in recent years have significantly advanced our knowledge of the molecular mechanisms involved in coronavirus RNA synthesis. Here, we briefly review these mechanisms and focus in particular on the structures and functions of the core replication-transcription complex (RTC) and other enzyme functions that can be recruited to this complex to fulfil additional functions, for example, in the context of 5' capping of viral mRNAs or in the context of mechanisms that control the processivity, replication fidelity, and backtracking of RTCs. Some of these recent studies provided fundamentally new insight into specific roles of previously identified genetic markers of coronaviruses and other nidoviruses, including specific functions in an unconventional RNA capping mechanism and potential roles in proofreading and discontinuous negative-strand RNA synthesis.},

Although advances in understanding the tumor immune microenvironment and the development of immunotherapies have transformed cancer treatment, clinical efficacy remains limited by suboptimal response rates and severe side effects. Recent integrative research in cancer biology, immune-oncology, and cancer microbiome research, enabled by omics technologies and advanced bioinformatics, has begun to reveal intricate links between the microbiome, cancer progression, and immune modulation. These findings underscore the microbiome's pivotal role in shaping both therapeutic efficacy and resistance mechanisms. Currently, nanotechnology, propelled into mainstream success through the development of COVID-19 mRNA vaccines, is offering new tools for precision oncology. Nanomaterials are now being explored not only for targeted drug delivery but also for monitoring and modulating the microbiome, with significant potential for biomarker discovery and personalized medicine. In this article, we explore the role of the microbiota in tumorigenesis and cancer therapy, with a particular focus on its crosstalk with the immune system. We highlight emerging microbiota-targeted therapeutic strategies and discuss how nanotechnology-based systems are being designed to modulate the microbiome-immune-cancer axis. Finally, we discuss future directions in leveraging the convergence of microbiome science, nanotechnology, and immunotherapy to advance cancer treatment.},

Approximately 10% of infected experience autonomic dysfunction, cardiovascular complications, and neurological impairments. While immune dysregulation, persistent viral reservoirs, chronic inflammation, gut dysbiosis, and vascular dysfunction are implicated, the exact pathophysiological mechanisms of Long COVID remain unclear. Additionally, treatment options are limited and challenging to prescribe due to symptom heterogeneity. Non-pharmacological interventions such as increased salt intake, elimination diets for gastrointestinal symptoms, and cognitive pacing for fatigue may not be sufficient for severe symptoms. Moreover, pharmacological interventions such as β-blockers, calcium channel blockers, pyridostigmine, antihistamines, and low-dose naltrexone can improve tachycardia, fatigue, and brain fog but there are no standardized guidelines. In light of evidence supporting a strong association of Long COVID with gut dysbiosis, probiotics have emerged as a promising intervention. Clinical studies have shown that Bacillus coagulans, Bacillus subtilis, Lactobacillus acidophilus, and Bifidobacterium species can improve fatigue, gastrointestinal health, and overall physical and mental well-being in Long COVID patients. Large-scale randomized controlled trials are warranted to validate probiotic efficacy in Long COVID and reduce burden on individual health and healthcare institutions.},

abstract = {BACKGROUND: As the acute response to the COVID-19 pandemic shifts to long-term management, the lasting effects of infection are becoming increasingly evident. Long COVID continues to challenge healthcare systems, with many healthcare professionals reporting uncertainty about assessment and referral pathways. This updated review examines recent international guidelines alongside Australian services to identify gaps between guidelines and practice. METHODS: Between April and October 2025, we searched for guidelines on Long COVID published in English and assessed their quality by applying the AGREE II appraisal tool. We also conducted a grey literature search to profile active Australian services providing Long COVID care. RESULTS: Three new or updated guidelines were published in the United States, Canada, and New South Wales, Australia. Together with the World Health Organisation, United Kingdom and New Zealand guidelines identified in the previous review, all emphasise integrated, primary care-led approaches. Notably, Australian service delivery remains fragmented, with a growing number of primary health practitioner-led private services operating largely under a fee-for-service model, leading to variations in access and affordability. Many hospital-based outpatient clinics have been absorbed into existing chronic-disease services. The most fundamental challenge is statistical invisibility: without an activated diagnostic code, services cannot reliably identify or follow people living with Long COVID. This invisibility limits both surveillance and service planning. DISCUSSION AND CONCLUSIONS: Australia is currently developing national clinical best-practice guidelines for ME/CFS, which may also benefit Long COVID; however, Australia remains behind comparable nations such as Canada, the United Kingdom, and the United States in developing and implementing the integrated, multidisciplinary care models recommended internationally. This has significant implications, namely that the rapid transition from hospital-based Long COVID clinics to primary care-led services has resulted in fragmented and uncoordinated care. Strengthening Australia’s response will require national leadership and investment in workforce training, sustainable funding for care coordination, improved public and professional awareness, the establishment of primary care-led multidisciplinary pathways, and the activation of a dedicated diagnostic code. Also importantly, shifting to a patient-centred approach and patient-practitioner collaborative model of care is essential to prepare the health system for managing Long COVID and future complex, multi-system conditions.},

To date, no systematic review has examined long-term trends in screen time use among children and adolescents that cover periods before and after the onset of the COVID-19 pandemic. This systematic review examined repeated cross-sectional studies to determine whether screen time use among children and adolescents changed over time. This systematic review was registered with PROSPERO (ID: CRD42021243869). The Web of Science, PubMed, Embase, and PsycINFO databases were searched to identify peer-reviewed studies that had been published in English, included data from at least two time points, and focused on children and adolescents between 0 and 19 years of age. The search was conducted without any restrictions on publication year. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Study quality was assessed using the Quality Assessment Tool for Studies with Diverse Designs. A narrative synthesis was conducted following the Synthesis Without Meta-analysis guidelines. This review identified 60 studies covering the period 1991-2022. The findings indicate that traditional TV watching declined while the use of computers and video games grew. Screen time increased significantly over the years, especially after the COVID-19 pandemic started. The studies reviewed varied in how they defined and measured screen time. The review underscores the importance of continued research and evidence-based policies to guide responsible technology use in the lives of young people.},

abstract = {Several conclusions have emerged regarding the impact of COVID-19 on the male reproductive system. This systematic review and meta-analysis aimed to provide a comprehensive update on the relationship between COVID-19 and male reproductive health. We investigated the effects of SARS-CoV-2 on various semen parameters, including semen volume, sperm concentration, sperm total count, total motility, progressive motility, morphology, and DNA fragmentation index (DFI). A literature review was conducted on all studies evaluating the impact of SARS-CoV-2 infection on male infertility from the beginning of 2019 through December 2023. Main electronic databases such as PubMed, Scopus, Cochrane Library, and Web of Science were used. The research question was based on the PECO framework, focusing on (Population) exposed to SARS-CoV-2 (Exposure), compared to uninfected men (Comparator), with conventional sperm parameters as the measured Outcome. The studies were divided into two groups for analysis: between-group comparisons, which compared sperm parameters of men recovered from COVID-19 to uninfected controls, and within-subject comparisons, which assessed sperm parameters in the same individuals before and after infection. Standardized mean differences (SMD) were calculated as effect sizes with 95% confidence intervals (CI) for each outcome. The DerSimonian-Laird method estimated between-study variance (τ[2]), while the Jackson method calculated confidence intervals for τ[2] and τ. Publication bias was assessed using funnel plots and Egger's test. This meta-analysis included two types of cohort studies: single-arm studies and those with a control group. In the single-arm studies, a statistically significant decrease in semen volume (p = 0.0023) was observed. Additionally, in the cohort studies with controls, there were statistically significant reductions in sperm concentration (p < 0.0001), total count (p = 0.0001), total motility (p = 0.0009), progressive sperm motility (0.0391), and DFI (0.04). This is the most up-to-date systematic review and meta-analysis incorporating cohort study data. The findings provide compelling evidence that SARS-CoV-2 infection adversely affects male reproductive health, particularly in terms of semen quality. The analysis reveals significant reductions in key semen parameters, including sperm count, concentration, total motility, and progressive motility. Adult maleand DFI.},

abstract = {Post-acute sequelae of COVID-19 (PASC) affect millions of people worldwide and are increasingly recognized as a disorder of failed innate immune resolution rather than a persistent viral infection. Emerging evidence shows that residual SARS-CoV-2 antigens, host-derived alarmins, reactivated latent viruses, and mucosal microbiome-derived products from oral-nasopharyngeal and gut reservoirs sustain the chronic activation of pattern-recognition receptors, inflammasomes, and complement pathways. In parallel, deficits in specialized pro-resolving mediators, impaired efferocytosis, and persistent tissue injury prevent physiological termination of inflammation. These unresolved cues drive long-lasting epigenetic and metabolic reprogramming of hematopoietic stem cells and myeloid lineages, creating maladaptive trained immunity states characterized by hyper-responsiveness or exhaustion of these cells. Thromboinflammatory processes, including aberrant NETosis and sustained interface signalingling, further reinforce self-perpetuating inflammatory circuits. Together, these pathways give rise to reproducible molecular endotypes, including thromboinflammatory, interferon-driven, and neuroinflammatory phenotypes, which explain clinical heterogeneity. Framing PASC as a disorder of impaired immune resolution within a mucosal microbial viral context provides a unifying mechanistic scaffold for biomarker identification and host-directed therapies. This review proposes that restoring active resolution programs, rebalancing metabolic-epigenetic networks, and dismantling pathogenic innate feedback loops are promising strategies for reversing the chronic immune imprint of PASC.},

abstract = {OBJECTIVE: This study aimed to explore and summarize the changes in depressive symptoms and their influencing factors among the elderly before and after the outbreak of the coronavirus disease 2019 (COVID-19) pandemic, so as to provide evidence-based references for the prevention and management of depression in the elderly. METHOD: By searching published in PubMed, EBSCOhost, Springer Link, Web of Science, Taylor and Francis databases, the literature on depression in older adults was collected using the 15-item Geriatric Depression Scale (GDS-15), Depression Scale (CDS-11) questionnaire and diagnostic interview (CDI-SF) as a tool. Among them, in the included literature, before January 2023 was identified as the pre-outbreak of the COVID-19 pandemic, and due to the differences in the time of full liberalization of countries, the beginning of 2023 to now was identified as the late outbreak of the COVID-19 pandemic, and Stata17 was used for meta-analysis. RESULTS: Thirteen pre-COVID-19 pandemic and seven post-COVID-19 pandemic literatures were included. A total of seven influencing factors were included. Before the COVID-19 pandemic: Before the COVID-19 pandemic, trends in potential risks for depression among older adults included: being female (OR = 1.464, 95% CI: 1.164~1.840,p < 0.001), being divorced or widowed (OR = 2.126, 95% CI: 1.170~3.862, P = 0.013), and having a chronic disease (OR = 1.174, 95% CI: 1.023~1.347, P = 0.022), age ≥ 70 years (OR = 1.336,95%CI: 0.850~2.102, P = 0.210), loneliness (OR = 2.450,95%CI: 2.445~2.455, P = < 0.001) and the junior middle school and the following qualifications (OR＝1.145, 95% CI:0.873~1.501, p＝0.327) were trends in potential risks for depression in older adults. Living alone (OR = 0.939, 95%CI: 0.417~2.116, P = 0.88), high school education or above (OR = 0.904,95%CI: 0.640~1.276, P = 0.564) were the lower risks. After the outbreak: being female (OR = 1.156, 95% CI: 0.675 ~ 1.980, P = 0.596), the junior middle school and the following qualifications (OR = 1.05, 95% CI: 0.964 ~ 1.143, P = 0.264), having a chronic disease (OR = 1.269, 95% CI: 1.003 ~ 1.605, P = 0.047), age ≥ 70 years (OR = 1.472, 95% CI: 0.861 ~ 2.517, P = 0.158), there is loneliness (OR = 2.913, 95% CI: 2.372 ~ 3.578, p < 0.001), live alone (OR = 1.627, 95% CI: 0.798 ~ 3.318, P = 0.180), high school education or above (OR = 1.053,95%CI:0.757 ~ 1.465, P = 0.757) were trends in potential risks for depression in older adults, divorce or widowed (OR = 0.482,95%CI:0.041 ~ 5.704, P = 0.563) were lower risks. CONCLUSIONS: The study found that the association patterns between depression in the elderly and five factors (divorced or widowed status, aged ≥ 70 years, loneliness, living alone, and high school education or above) exhibited distinct characteristics before and after the pandemic. Among these, loneliness and chronic diseases were consistently significant risk factors for depression in the elderly, and the strength of the association between loneliness and depression was further enhanced in the post-pandemic period. Notably, the significant association between female gender and depression observed in the pre-pandemic period no longer existed in the post-pandemic period. This change is speculated to be related to adjustments in the coverage of social support after the pandemic, which requires further verification in subsequent studies. Based on the above association characteristics, targeted intervention measures can be adopted in the post-pandemic period, such as striving to alleviate loneliness in the elderly, strengthening health monitoring for key groups including the elderly living alone and those aged ≥ 70 years, and promoting the organic integration of chronic disease management and psychological assessment, so as to effectively reduce the risk of depression in the elderly.},

abstract = {INTRODUCTION: The COVID-19 pandemic had a profound impact on global health, notably affecting patients with non-COVID-19 conditions, who faced substantial disruptions in their treatment and care. The aim of this narrative review was to identify the main indicators used in literature to evaluate the indirect impact of COVID-19 on health and wellbeing.

METHOD: A literature search was conducted using PubMed from January 2021 to November 2022. The indicators were categorized into five main groups: burden of disease (BoD), life expectancy (LE), health-related quality of life (HRQoL), cost of illness and mental health status and were retrieved from 20 scientific articles.

RESULTS: Disability-adjusted life years (DALYs) revealed substantial health losses; a decrease in LE was observed, with inequalities across population subgroups; HRQoL showed impairments in physical functioning, daily activities and emotional well-being; productivity losses were economically relevant and varied by context and elevated symptoms of anxiety and depression were reported.

DISCUSSION: The compiled indicators may contribute to the development of sustainable pandemic mitigation policies.},

This review outlines the clinical features of fungal complications, proposing a "virus-driven immune reprogramming" framework. It highlights how viral infections disrupt immune barriers, impair the Th17-IL-17 antifungal axis, attenuate platelet immune function, and involve unique pathogen interactions, creating a host immune microenvironment that is more susceptible to fungal invasion. Understanding these immune-injury mechanisms underscores the clinical importance of earlier surveillance of secondary fungal disease and informs the development of mechanism-guided therapeutic approaches to improve patient outcomes.},

abstract = {Transitioning from pre-clinical to clinical phases of medical education represents a unique challenge as students learn most content through self-directed learning (SDL), rather than the more prescriptive pre-clinical curriculum. There is a range of SDL study techniques employed by medical students on placement. The COVID-19 pandemic accelerated the adoption of digital resources, prompting a need to reassess the study techniques that best support clinical-year medical students. However, there is a lack of research on which study techniques Australian clinical-year medical students find most effective. The objective of this study is to evaluate the evidence on student-perceived utility of common study techniques for SDL whilst on clinical placement in Australia. A qualitative scoping review of literature on PubMed and Medline Ovid was performed in 2024. Study inclusion criteria for articles were published articles, English language, publication within 20 years, and focus on clinical-year medical students. Exclusion criteria were review articles, investigations focusing on a specific educational intervention, and studies including only pre-clinical students. Studies were qualitatively appraised and synthesised by tabulation in Microsoft Excel (Microsoft Corp., Redmond, WA, US). Risk of bias analysis was not performed. Nine studies from Australia, the USA, the UK, Thailand, Saudi Arabia, and Malaysia were analysed. This included seven cross-sectional, one mixed-methods, and one qualitative analysis. Sample size ranged from 12 to 350 students. Only two studies were conducted after the COVID-19 pandemic. Overall, the results of the included studies demonstrate a consistent trend towards third-party online tools, including question banks, mobile applications, and revision courses for SDL. The strength of evidence on students' perceived efficacy of study techniques in the post-pandemic era presented is limited due to the small number of included studies and the lack of formal study appraisal. There is also poor generalisability of pre-pandemic and international studies to the contemporary Australian context. As there is a lack of a standardised tool to evaluate study technique utility, comparison between studies is difficult. Ongoing research is required to develop evidence-based guidelines that can assist students in commencing SDL whilst on clinical placement.},

abstract = {BACKGROUND: Cardiac injury is a frequent and severe complication of COVID-19, yet the molecular mechanisms driving myocardial involvement remain incompletely understood. Dysregulated autophagy, telomerase/telomere biology, and endothelial dysfunction have emerged as biologically plausible and potentially interconnected contributors to COVID-19-associated cardiac injury.

METHODS: We conducted a narrative, evidence-graded review of literature retrieved from PubMed and EMBASE, with Google Scholar used selectively as a supplementary source to capture emerging or cross-disciplinary studies. Eligible studies included human investigations and relevant animal models reporting genetic, epigenetic, or molecular alterations in autophagy, telomerase, or endothelial pathways with cardiovascular relevance. Non-English publications, studies lacking primary data, and reports unrelated to cardiovascular or systemic disease mechanisms were excluded. Evidence was stratified as Level I (direct evidence in COVID-19-associated cardiac injury), Level II (COVID-19 systemic or vascular evidence with plausible cardiac relevance), and Level III (non-COVID cardiovascular or systemic disease; hypothesis-generating).

FINDINGS: Across viral, cardiovascular, and systemic contexts, key candidate genes, including ATG5, ATG7, Beclin-1, TERT, ICAM1, and eNOS -emerged as potential mediators of COVID-19-related cardiac injury. While endothelial activation is supported by relatively consistent clinical and molecular evidence, direct cardiac-tissue data linking autophagy and telomerase pathways to COVID-19-associated myocardial injury remain limited. These gaps highlight substantial uncertainty regarding causal mechanisms and inter-individual susceptibility.

CONCLUSION: Autophagy dysregulation, telomere attrition, and endothelial dysfunction represent convergent and biologically plausible mechanisms contributing to COVID-19-associated cardiac injury; however, current evidence remains largely indirect and derived from systemic or vascular compartments rather than cardiac tissue. Cardiac-specific, longitudinal genetic and epigenetic studies are required before these pathways can be considered for biomarker development or therapeutic targeting.},

abstract = {UNLABELLED: The COVID-19 pandemic exacerbated many known risk factors for post-traumatic stress disorder (PTSD) among healthcare workers. This systematic review and meta-analysis examines pooled prevalence estimates of probable PTSD among this cohort prior to COVID-19 compared to during COVID-19 and investigates time trends in prevalence. Systematic multi-database literature searches were conducted to identify studies published between January 2017 and July 2023. Included studies reported the prevalence of probable PTSD, measured by validated screening tools, in clinical healthcare workers. Two reviewers independently conducted study screening, data extraction, and quality assessment. Random-effects meta-analyses were performed to estimate pooled prevalence of probable PTSD among healthcare workers in each time period. Subgroup analyses were carried out for year, profession, quality of study, COVID-19 mortality rates, and income level within the country of study. Screening identified 21 papers comprising 11,838 healthcare workers published in the 3 years preceding the pandemic, and 129 papers reporting on 130,363 healthcare workers during the pandemic. The pooled prevalence estimate of probable PTSD prior to the pandemic was 15.5% (95% CI: 12.3-19.3%) and this significantly increased during the pandemic to 24.8% (95% CI: 22.0-27.8%), peaking early in the pandemic in 2020 before returning to pre-pandemic levels in 2022. During the pandemic, prevalence estimates were significantly higher among nurses and those in countries with high COVID-19 mortality rates, whilst no significant difference was observed between studies conducted in high-income versus low- and middle-income countries. Substantial heterogeneity was observed. The findings of this review suggest that prevalence of PTSD among healthcare workers significantly increased following the COVID-19 outbreak. By the third year of the pandemic, probable PTSD prevalence rates appear to return to pre-pandemic levels, although these levels remain concerningly high. These findings support the call for targeted interventions to protect healthcare worker wellbeing, particularly during healthcare emergencies.

DESIGN: A panel of 68 international experts, representing 13 international organizations, as well as six methodologists, was convened. A formal conflict-of-interest policy was developed at the onset of the process and applied throughout. Teleconferences and electronic-based discussion among the chairs, co-chairs, methodologists, and subgroup leads as well as within subgroups, served as an integral part of the guideline development process.

METHODS: New priority topics and recommendations from the prior guideline iteration were used to identify Population, Intervention, Control, and Outcomes (PICO) questions likely to have new or updated evidence. We conducted a systematic review to identify the best available evidence, summarized the evidence, and then assessed the quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation approach. We used the evidence-to-decision framework to formulate recommendations as strong or conditional, or as a good practice statement. "In our practice," statements were included when evidence was inconclusive to issue a recommendation but the panel felt that some guidance based on practice patterns may be appropriate.

RESULTS: The panel provided 61 statements on the management of children with sepsis or septic shock. Overall, five were strong recommendations, 24 were conditional recommendations, and ten were good practice statements. For 22 PICO questions, no recommendations could be made, but, for seven of these, "in our practice" statements were provided. Compared with the 2020 guidelines, 20 recommendations were new, 13 were updated for clarity and/or new evidence, six were reviewed but not changed, and 22 were carried forward based on consensus of the panel that new evidence was not available. Only three recommendations were based on high or moderate certainty of evidence.

CONCLUSIONS: Updated management guidelines were issued by a panel of international experts for the best care of children with sepsis or septic shock, acknowledging that most aspects of care continue to have relatively low quality of evidence.},

abstract = {The ever-present threat of new viral epidemics makes the scientific community relentlessly work on the development of universal methods of antiviral therapy. The development of broad-spectrum antivirals (BSAs) focuses either on substances acting directly on viral proteins (direct-acting antivirals [DAA]) or on substances directed at the cell's own proteins (host-targeting antivirals [HTA]). Decades of development have led to the market entry of a number of DAAs with a wide range of antiviral activities; however, their clinical approval has been obtained for individual infections. HTAs have a number of advantages over DAAs, such as a wider range of antiviral activities and a high genetic barrier to viral resistance, which is undoubtedly important when preparing for a battle with an unknown pathogen. The COVID-19 pandemic has allowed for multiple clinical trials for repurposed HTAs, previously licensed for the treatment of other diseases, including cancer. Despite the enormous work done, the arsenal of BSAs capable of protecting against future pandemics caused by pathogen X is very limited. In this review, we described data on the most studied DAAs and HTAs, effective against at least two unrelated viral pathogens, focusing on those that have been studied in late preclinical and clinical trials. In the end, we highlighted alternative new approaches such as CRISPR-Cas therapy.},

abstract = {Heart failure (HF) remains a leading cause of morbidity, mortality, and healthcare utilization worldwide, despite the availability of effective evidence-based therapies. The principal challenge is no longer the absence of treatment options but the limited capacity of traditional care models to deliver guidelinedirected medical therapy (GDMT) consistently and at scale. The COVID-19 pandemic exposed the fragility of hospital-centered HF care, highlighting the need for more resilient, patient-centered management strategies. Remote monitoring (RM) has been proposed as a solution, yet its clinical impact has been inconsistent due to fragmented data streams, declining patient adherence, and heavy reliance on continuous human oversight. Artificial intelligence (AI) offers an opportunity to address these limitations by integrating multidimensional clinical data, enabling earlier detection of deterioration, supporting adherence, and prioritizing clinically meaningful interventions. Emerging evidence suggests that AI-assisted workflows can accelerate GDMT optimization and improve surrogate and clinical outcomes when implemented within supervised care pathways. This has led to the concept of next-generation remote monitoring (NGRM), in which AI analyzes longitudinal physiological and behavioral signals to generate context-aware alerts and actionable recommendations while reducing clinical workload. Successful implementation, however, requires rigorous validation, clear governance, integration with clinical workflows, and safeguards for safety, equity, and accountability. When embedded within structured HF care pathways, AI-enabled monitoring may help bridge the persistent gap between evidence and real-world implementation.},

abstract = {Exacerbations of chronic obstructive pulmonary disease (ECOPD) represent key events in the natural history of COPD and are associated with several adverse outcomes. Respiratory infections are major and potentially modifiable triggers of ECOPD, with viral pathogens such as the influenza virus, respiratory syncytial virus (RSV), and SARS-CoV-2, as well as bacterial infections caused by Streptococcus pneumoniae, playing a central role. This narrative review examines the current evidence supporting vaccination as a preventive strategy for ECOPD and discusses its translation into clinical practice. The biological rationale for vaccination in COPD is reviewed, including disease-related immune dysregulation, impaired mucociliary clearance, and increased susceptibility to respiratory pathogens. Evidence from randomized clinical trials, observational studies, meta-analyses, and real-world data is summarized for pneumococcal, influenza, SARS-CoV-2, and RSV vaccines. Pneumococcal vaccination has been shown to reduce the burden of community-acquired pneumonia and invasive pneumococcal disease, with conjugate and higher-valent vaccines providing enhanced immunogenicity in older and high-risk adults. Influenza vaccination consistently reduces severe exacerbations, hospitalizations, and mortality, with additional cardioprotective effects of relevance in COPD. SARS-CoV-2 vaccination markedly lowers the risk of severe COVID-19 and related respiratory deterioration in COPD, while recently licensed RSV vaccines offer a novel opportunity to prevent RSV-associated lower respiratory tract disease and potentially reduce exacerbation risk. Patient populations most likely to benefit from vaccination include frequent exacerbators, older adults, individuals with severe airflow limitation, multimorbidity, immune dysfunction, infection-prone phenotypes, and socially vulnerable groups. Future perspectives include precision vaccination strategies, novel vaccine platforms, coadministration approaches, and interventions to improve vaccine uptake. Vaccination emerges as a cornerstone of ECOPD prevention, with substantial potential to reduce exacerbation burden and improve long-term outcomes in COPD.},

Closing the racial wealth gap can, in turn, contribute significantly to reducing racial disparities in health, including overall life expectancy. By providing a comprehensive and actionable plan, it becomes clear that the primary obstacle to adoption of reparations by the US Congress is political resistance.

CASE PRESENTATION: A 60-year-old woman with history of kidney transplantation was admitted for recurrent fever and positive SARS-CoV-2 antigen on pharyngeal swab testing. The patient developed rapid-onset respiratory distress secondary to progressive pulmonary infection and received assisted mechanical ventilation. Microbiological sequencing and culture of bronchoalveolar lavage fluid and sputum, as well as serological tests, revealed the presence of Aspergillus fumigatus, Aspergillus lentulus and Cryptococcus neoformans, along with multiple bacterial and viral pathogens. Following a course of combined antifungal, antibacterial, and antiviral therapies, the patient was successfully weaned off mechanical ventilation. The lung exudates and the large cavitary abscess were absorbed completely. CONCLUSIONS: We reported successful treatment of a rare case of concurrent aspergillosis and cryptococcosis following SARS-CoV-2 pneumonia in a kidney transplantation recipient. The severe fungal infection was probably attributed to the immunosuppressive status associated with a history of solid organ transplantation, as well as prolonged administration of glucocorticoid and antibiotics.},

We systematically searched PubMed and a public repository on shedding data and included 33 studies that met at least one of our objectives. Among 32 studies, the proportion of SARS-CoV-2-infected individuals with detectable virus in stool ranged from 18 to 100%, with a pooled estimate of 54% (95% CI: 52-56%). Stratification by four clinical severity categories, ranging from asymptomatic to critically ill, showed no significant differences among categories (p-value = 0.49). The proportion of individuals with detectable SARS-CoV-2 RNA in stool was higher in children (61%) than in adults (53%; p-value = 0.02). In half of the individuals who initially shed the virus in stool, it remained detectable for an estimated 22 days post-symptom onset. Three studies documented viral load kinetics, indicating a peak between days 3 and 9. Twenty-five studies reported maximum shedding durations ranging from 2 to 12 weeks. Our review summarizes the frequency, dynamics, and duration of SARS-CoV-2 shedding in stool and may serve as a valuable foundation for modelling efforts involving faecal shedding indicators.},

abstract = {Glucose-6-phosphate dehydrogenase (G6PD), the rate-limiting enzyme of the pentose phosphate pathway (PPP), plays a pivotal role in immune regulation by regulating metabolic reprogramming and redox homeostasis of immune cells. It mediates the production of nicotinamide adenine dinucleotide phosphate (NADPH) and ribose-5-phosphate (R5P), which are essential for the activation, proliferation, and effector function of T lymphocytes, B lymphocytes, macrophages, and neutrophils-specifically promoting T/B cell-mediated adaptive immunity and macrophage/neutrophil-mediated innate immune responses. Abnormal G6PD activity (deficiency or overexpression) is closely associated with the pathogenesis of immune-related diseases: G6PD deficiency increases susceptibility to autoimmune diseases (e.g., rheumatoid arthritis, systemic lupus erythematosus) and infectious diseases (e.g., hepatitis, malaria, COVID-19) by inducing oxidative stress and immune cell dysfunction; in tumor immunity, G6PD dualistically promotes tumor cell proliferation while regulating anti-tumor immunity via modulating cytoxic D8[+] T cell exhaustion and macrophage polarization. Additionally, G6PD-targeted immunotherapies, including small-molecule inhibitors and gene therapy, have shown promising preclinical potential for treating immune-related diseases. These findings highlight G6PD as a key metabolic-immune hub, providing critical theoretical basis for understanding immune regulation mechanisms and developing novel diagnostic and therapeutic strategies for autoimmune diseases, infectious diseases, and tumors.},

abstract = {The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has resulted in millions of deaths worldwide and has now become a major respiratory infectious disease. Beyond the direct effects of the viral infection, one of the most significant and concerning issues to emerge is the exacerbated threat of antimicrobial resistance (AMR) by the indirect impacts of COVID-19. Early in the pandemic, widespread empirical antibiotic prescribing occurred despite low bacterial co-infection rates. In addition, azithromycin, whose antiviral effect remains unproven, was frequently used. This high, often unnecessary consumption, coupled with disrupted antimicrobial stewardship (AMS) and infection prevention and control (IPC) programs, created conditions favoring the emergence and spread of AMR. In patients with severe COVID-19, multidrug-resistant organisms were frequently implicated in secondary infections, particularly in intensive care units (ICUs). Nevertheless, previous studies analyzing AMR metrics before and during the COVID-19 pandemic have shown inconsistent results. Strategies to mitigate the COVID-19 pandemic, such as enhanced surveillance, social distancing resulting in lower respiratory infections, and strengthened IPC and targeted AMS interventions, could play protective roles to inhibit the development of AMR. Additionally, targeted interventions-such as prospective audit and feedback, biomarker-guided antibiotic discontinuation, diagnostic stewardship using a rapid molecular test to distinguish viral from bacterial infections, embedding AMS decision support into electronic medical records, and tailoring interventions to high-risk settings such as ICUs-demonstrated the feasibility of reducing unnecessary antimicrobial use (AMU) even during crisis conditions. Also, vaccination against SARS-CoV-2 may indirectly reduce AMU and AMR by lowering the incidence of severe disease and secondary bacterial infections. Future COVID-19-specific AMS frameworks must integrate these experiences during the pandemic. This review synthesizes current evidence on the interplay between COVID-19, AMR, and AMU, and outlines stewardship strategies to reduce AMR in COVID-19 management.},

Republic of Korea's experience provides insights into pediatric-focused pandemic response. This review analyzes the impact of COVID-19 on children in Korea and evaluates the national response. This review encompasses the Korea Disease Control and Prevention Agency COVID-19 response white paper, National Medical Center response report, Ministry of Education and Seoul Metropolitan Office of Education white papers, focusing on pediatric data and policies. Key findings were supplemented with international studies on pediatric COVID-19 epidemiology, vaccination, and educational impacts. Children in Korea accounted for a substantial number of COVID-19 cases during omicron wave, yet severe outcomes remained rare. Surveillance adaptations included dedicated monitoring of pediatric multisystem inflammatory syndrome through antibody testing. The healthcare system rapidly adjusted to pediatric needs by allowing home isolation for mild cases and by permitting caregiver accompaniment during pediatric hospital isolation. Vaccine rollout for adolescents began in 2021 and for ages 5-11 in 2022, with an initial policy focusing on high-risk children and voluntary uptake for others. In the education sector, Korea implemented remote learning infrastructure, distributing devices and expanding internet access to bridge the digital divide. Korea's pandemic response illustrates the importance of pediatric-specific strategies: surveillance, child-friendly healthcare protocols, risk communication to improve vaccine acceptance, and treating schools and child services as essential infrastructure.},

This review summarizes evidence from nationwide registries, cohort studies, and clinical trials in Korea, alongside global findings, to describe the epidemiology, risk factors, therapeutic interventions, and prognostic models for severe COVID-19. Between January 2020 and August 2023, Korea reported more than 34 million confirmed cases, with 38,112 classified as severe and 35,608 deaths, yielding one of the lowest case fatality rates among member countries comprising the Organisation for Economic Co-operation and Development. Severity was strongly associated with advanced age and comorbidities such as cardiovascular disease, diabetes mellitus, cancer, psychiatric disorders, and immunocompromised states, including solid organ transplantation and hematologic malignancies. Other risk modifiers included obesity, chronic kidney disease, asthma, and prolonged glucocorticoid therapy. Protective factors included vaccination, regular physical activity, and, in some studies, specific pharmacologic agents. The effectiveness of vaccines was consistently demonstrated, with booster doses markedly reducing hospitalization and mortality, including in high-risk groups such as pregnant women, patients with cancer, and transplant recipients. Antiviral therapies, notably nirmatrelvir/ritonavir and molnupiravir, significantly reduced severe outcomes, while immunomodulators such as dexamethasone and tocilizumab improved recovery in patients with severe disease. Advanced interventions, including extracorporeal membrane oxygenation and lung transplantation, were used for refractory respiratory failure, with favorable survival observed in selected patients. Prognostic models integrating clinical, radiological, and machine learning approaches have been developed to predict disease progression, supporting early risk stratification and resource allocation. The rapid generation of evidence on predicting, preventing, and treating severe disease is a critical element of pandemic preparedness. Although COVID-19 has transitioned to an endemic disease, sustaining and advancing the research expertise and infrastructure developed during the pandemic remains essential for responding to future emerging infectious disease outbreaks.},

abstract = {Coronavirus disease 2019 (COVID-19) imposed substantial health and social burdens worldwide, disrupting healthcare delivery and challenging public health governance. Korea's early, coordinated response was associated with low mortality and maintained essential services, yet the prolonged pandemic exposed structural inequalities, workforce strain, and psychosocial impacts. To comprehensively understand these multidimensional effects, this review synthesizes systematic and narrative evidence on the clinical, epidemiologic, and societal consequences of COVID-19 in Korea. We conducted a combined systematic and narrative review of Korean evidence (2020-2025). The systematic review included studies from PubMed, Embase, KoreaMed, and KMbase, supplemented by manual journal searches. Eligible studies addressed key epidemiologic indicators, including seroprevalence, mortality among patients with comorbidities, severe outcomes in high-risk groups, and vaccination coverage by comorbidity. Quality was assessed using Joanna Briggs Institute tools. We additionally examined government white papers, national reports, policy briefs, and peer-reviewed articles to contextualize epidemiologic findings, synthesizing materials across health burden, healthcare system changes, social consequences, and policy responses. Twenty-four epidemiologic studies and 72 narrative sources were included. Seroprevalence remained below 1% during the early pandemic, increasing sharply after omicron's emergence. Patients with chronic illnesses consistently experienced higher risks of severe outcomes and mortality, while high-risk groups showed elevated odds of intensive care use and complications. Alongside clinical patterns, national data documented substantial reductions in outpatient visits, elective procedures, emergency care, and pediatric services. Burnout and psychological distress intensified among healthcare workers, while prolonged distancing and economic disruption contributed to widening social fatigue. Policy responses and vaccination improved population outcomes, although gaps persisted in communication strategies and addressing disparities across age, socioeconomic status, and comorbidity groups. Korea's experience underscores that preparedness must align clinical efficiency with social equity. Strengthening primary and emergency care, ensuring fair compensation and workforce protection, and maintaining transparent risk communication are essential for building a resilient, inclusive public health system to withstand future pandemics.},

In Korea, six vaccines were approved, and the rapid rollout initiated in February 2021 contributed to comparatively low global mortality. As the epidemiological landscape of COVID-19 evolved and evidence on vaccine immunogenicity and safety accumulated, Korea adapted its vaccination strategies. During the 2024-2025 season, two mRNA vaccines (Pfizer-BioNTech and Moderna) and one recombinant protein vaccine (Novavax) targeting JN.1 lineage were administered primarily to high-risk groups. Beginning in October 2025, two mRNA vaccines (Pfizer-BioNTech and Moderna) adapted to LP.8.1 variant have been introduced as the updated 2025-2026 season formulations. Although safety concerns arose initially, Korean studies confirmed that COVID-19 vaccines provided strong effectiveness and acceptable safety, consistent with international findings. To enhance preparedness for future pandemics and epidemics, sustaining surveillance systems and maintaining updated vaccination policies are critical to ensure effective public health responses.},

abstract = {Vaccination programs have averted millions of childhood deaths, yet vaccine-preventable diseases (VPDs) continue to resurge as coverage declines and pathogen evolution undermines previously successful vaccines. Anticipating resurgence is a public health priority. We review theoretical and empirical advances in the study of early warning signals (EWS) of epidemic transitions, with a focus on critical slowing down (CSD) - a phenomenon in which recovery from perturbations becomes slower near the epidemic threshold. We summarize the mechanisms that generate CSD, indicators that can be extracted from surveillance data, and the conditions under which signals may be detectable. We then examine case studies to illustrate the opportunities and challenges of applying EWS to VPD resurgence. Theory and computer simulations show that CSD can precede both elimination and resurgence, with increases in variance and autocorrelation calculated from disease surveillance reports emerging as consistent indicators. Empirical evidence supports this potential, though performance depends on noise structure, seasonality, spatial clustering, and outbreak responses. Case studies highlight both successful applications and contexts where signals were weak or absent. EWS offer a promising framework for anticipating VPD resurgence, but further research is required to refine methods, integrate mechanistic and social-behavioral drivers, and evaluate applicability across pathogens and settings.},

abstract = {This analysis of the Slovak health system reviews developments in governance, organization, financing and delivery of care, health reforms and health system performance. Slovakia, a central European country with a population of 5.4 million, continues to face significant health and health care system challenges. Slovakia's health system is founded on universal coverage with compulsory health insurance, a broad benefits package and a competitive insurance model. Although life expectancy improved between 2000 and 2019, the COVID-19 pandemic reversed gains, and in 2023 Slovak life expectancy remained three years below the European Union (EU) average. Circulatory diseases and cancer are the leading causes of death, and noncommunicable diseases such as diabetes and mental illness are rising. Nearly one third of all mortality is linked to behavioural risk factors, including poor diet, high smoking rates, low physical activity and obesity. Slovakia's health care system features competition among three insurers - one state-owned (Všeobecná zdravotná poisťovňa, VšZP) and two private. Since major reforms in 2004, the system has decentralized responsibilities and adopted selective contracting to enhance efficiency. However, structural weaknesses remain, particularly in financial sustainability, accessibility and equity. Health spending from public sources was 8.3% of gross domestic product (GDP) in 2024, yet out-of-pocket (OOP) payments account for nearly 19% of expenditures, disproportionately burdening low-income households. Workforce shortages, especially in nursing and primary care, are worsened by emigration and an ageing staff. Urban-rural disparities persist, with modern infrastructure and specialized services concentrated in cities. Digital health advancements, such as the National Health Information System (NHIS), aim to modernize care and facilitate telemedicine, though implementation is uneven. Ongoing reforms target cost containment, infrastructure optimization and integration of long-term care (LTC). Key priorities include addressing regional disparities, improving workforce retention, reducing waiting times and enhancing eHealth adoption. Despite universal coverage, Slovakia must address persistent gaps in health outcomes, resource distribution and system resilience to meet the needs of its population.},

The analysis identifies 6 thematic areas: shared vision and transparency, governance engagement, incentive alignment, administrative burden, physician well-being, technology and innovation, and organizational trust and culture. The literature consistently documents the persistence of misalignment: physicians cite loss of autonomy and administrative overload, while administrators must manage costs and ensure compliance. Evidence from health systems such as Mayo Clinic, Cleveland Clinic, and rural hospitals demonstrates that structured engagement strategies can mitigate these divides. Bridging the physician-administrator divide is critical for value-based care. In rural areas where hospital closures and workforce shortages are acute, collaborative models are urgently needed. The proposed framework highlights actionable strategies to reduce burnout, enhance retention, and strengthen patient-centered outcomes.},

abstract = {Clinical, experimental, and computational evidence of COVID-19 virulence and infectivity has been linked to SARS-CoV-2 shell disorder. A strong link was first discovered using an AI disorder-predicting tool, which detected an unusually hard (low disorder) outer shell among all SARS-CoV-2-related viruses but not in the 2003 SARS-CoV-1. This could account for the high infectivity found in SARS-CoV-2-but not in SARS-CoV-1-as it is believed that hard shells protect viral particles from the onslaught of the antimicrobial enzymes present in the respiratory system and saliva. As a result, much larger quantities of particles are shed by COVID-19 patients. Abnormally hard outer shells (M) are associated with burrowing animals, e.g., pangolins, and SARS-CoV-2 likely acquired these shells due to its long-term evolutionary interactions with pangolins. As for virulence, the inner shell of SARS-CoV-2 (N) has been found to exhibit lower disorder than that of SARS-CoV-1. This lower disorder is consistent with the fact that SARS-CoV-2 is less virulent than SARS-CoV-1, as higher disorder in the inner shell is associated with more efficient protein-protein binding during replication. The link between N/M disorder and virulence or infectivity falls under the umbrella of shell disorder models (SDMs), which can connect virulence, infectivity, and long COVID under one coherent concept. Evidence of the reliability and reproducibility of SDMs as applied to COVID-19 is examined. The hard M that is resisting the antimicrobial enzymes in the respiratory system can be extended to immunological enzymes, especially those found in phagocytes such as macrophages, which can therefore become a reservoir for the virus.},

We conducted a narrative review of the literature on post-vaccination dermatomyositis, focusing on clinical features, autoantibody profiles, therapeutic approaches, and outcomes. The review was enriched by the inclusion of a new case: a 60-year-old woman who developed anti-MDA5-positive dermatomyositis two weeks after receiving her fourth dose of the BNT162b2 (Pfizer/BioNTech) vaccine. She presented predominantly with cutaneous and articular manifestations in the absence of interstitial lung disease. Treatment with oral prednisone, intravenous alprostadil, and the Janus kinase inhibitor tofacitinib resulted in marked clinical improvement. This case, together with the literature review, illustrates both typical and atypical presentations of vaccine-associated anti-MDA5 DM, highlights diagnostic challenges without lung involvement, and suggests JAK inhibition as a potential therapeutic option, contributing to a more comprehensive understanding of post-vaccination dermatomyositis.},

However, despite rapid technological advancement and preliminary adoption accelerated by the COVID-19 pandemic, a significant implementation gap persists. This narrative review explores the causes of this gap, highlighting several examples from early development to final implementation. These show that technical validation alone is insufficient. Success depends on alignment with clinical need, robust external validation, patient empowerment and sustainable funding models. Furthermore, other systemic barriers include data privacy concerns and lack of transparency by commercial companies. To improve adoption and translate promise to practice, more international alignment of regulations and international collaboration is needed. Lessons must be learned from promising initiatives that did not reach clinical care, as much as from their successful counterparts. Ultimately, a comprehensive redesign of healthcare will be undertaken, with digital diagnostics and therapeutics both embedded as critical components rather than add-ons. This demands a multi-stakeholder effort involving governments, regulatory bodies, insurance providers, industry, research funders, hospital leadership, clinicians and, most importantly, patients.},

abstract = {INTRODUCTION: The bidirectional communication between the lungs and the central nervous system, known as the lung-brain axis, has emerged as an important framework for understanding systemic mechanisms influencing neurological health. Increasing evidence indicates that pulmonary inflammation, respiratory microbiota alterations, and environmental exposures can modulate neuroinflammation, blood-brain barrier integrity, and microglial activation.

AREAS COVERED: This review summarizes current experimental and clinical evidence describing the molecular, microbial, and neuroimmune mechanisms underlying the lung-brain axis. Particular emphasis is placed on the role of the respiratory microbiota across the upper and lower airways and its interaction with immune signaling pathways. In addition, the neurological consequences of pulmonary diseases and infections, including asthma and COVID-19, are discussed, highlighting neuroanatomical, humoral, and immunological routes linking pulmonary and brain physiology.

EXPERT OPINION: Emerging data suggest that the respiratory system functions as an immunometabolic interface capable of influencing neuroimmune regulation and brain function. Integrative approaches combining respiratory microbiota profiling, immune biomarkers, and neuroimaging may help clarify causal mechanisms and support the development of novel diagnostic and therapeutic strategies for neurological and post-infectious conditions.},

abstract = {The gut-lung axis represents a bidirectional communication network through which the gut microbiota (GM) influences respiratory health. This mini-review synthesizes clinical evidence on the role of the GM in lung diseases. We focused exclusively on human clinical trials, randomized controlled trials, meta-analyses, and systematic reviews, sourced from major databases after duplicate removal. The evidence indicates that GM dysbiosis is a significant risk factor for the susceptibility and severity of various respiratory conditions, including asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis (CF), and infections, such as COVID-19 and pneumonia. Specific microbial signatures and metabolic profiles, particularly involving short-chain fatty acids (SCFAs), are associated with disease states and outcomes. Interventions like probiotics, prebiotics, synbiotics, and fecal microbiota transplantation (FMT) show promise in modulating the GM and improving clinical parameters, though their efficacy can be inconsistent and influenced by confounding factors. In conclusion, the GM is a promising therapeutic target for lung diseases. However, future research must prioritize large-scale, longitudinal clinical trials and deeper mechanistic investigations to establish causality and develop effective, personalized microbiome-based therapies.},

This systematic review assessed published prediction models for overall and all-cause mortality in adults with cancer aged 65 years or older. We searched for publications in Ovid Embase, Ovid Medline, Cochrane CENTRAL, and EBSCO CINAHL on Nov 25, 2022, and updated the search on Feb 24, 2024. We included 250 studies, of which 182 (72·8%) reported both model development and internal validation. 176 (70·4%) of 250 models predicted overall survival; 40 (16·0%) models focused on lung cancer and 30 (12·0%) models on colorectal cancer. 43 (17·2%) models were specifically developed for older adults; 138 (55·2%) models did not incorporate geriatric variables such as comorbidities, nutrition, and cognition. Risk of bias was high in all models, largely owing to inappropriate handling of continuous predictors, univariable selection of predictors, and inadequate control for overfitting. These limitations preclude clinical use. Future models predicting overall and all-cause mortality in older adults with cancer should adhere to existing methodological guidelines and incorporate geriatric domains.},

METHODS: A systematic bibliographic search of case reports, cross-sectional and longitudinal studies was conducted between March 12[th], 2020, and December 20[th], 2024, among studies evaluating the impact of the COVID-19 pandemic on symptoms and functioning for individuals with pre-existing mental health disorders and for those who presented with self-harm or died by probable suicide in the Republic of Ireland. Studies were independently screened by two reviewers according to inclusion and exclusion criteria, with selected variables extracted and summarised. Risk of bias assessments and narrative synthesis of included studies were conducted.

RESULTS: Twenty-eight studies met inclusion criteria. Findings were heterogeneous and disorder specific. An increase in presentations of self-harm, anxiety disorders, and eating disorders to child and adolescent mental health services and emergency departments was noted, with relative stability of symptoms in other cohorts including bipolar disorder and treatment-resistant schizophrenia. Significant symptom deterioration, with poor quality of life and functioning was demonstrated in individuals with emotionally unstable personality disorder both cross-sectionally and longitudinally.

CONCLUSIONS: Most people with pre-existing mental disorders did not experience significant exacerbation associated with the pandemic, with exception of those with eating disorders and EUPD.},

While physical exercise has been shown to exert protective effects on cognition, the role of respiratory muscle training (RMT) remains unclear. The aim of this review was to investigate the effects of RMT on cognitive function and cognitive decline. Respiratory muscle training has been implemented in older adults with elevated blood pressure, post-COVID-19 patients, patients with chronic obstructive pulmonary disease (COPD), and patients with obstructive sleep apnea (OSA). There is only preliminary evidence regarding the effectiveness of inspiratory muscle training (IMT) on cognitive function, with only one study reporting statistically significant between-group differences (i.e., respiratory muscle training vs. control) in specific cognitive domains. Although respiratory muscle training appears to be a potentially promising intervention for improving cognitive function, the current evidence is limited. Further well-designed randomized controlled trials are required to draw definitive conclusions regarding its preventive role in cognitive decline and dementia.},

abstract = {BACKGROUND: Burnout, defined by emotional exhaustion, depersonalization, and reduced personal accomplishment, is increasingly recognized as a significant threat to staff wellbeing, organizational performance, and patient safety in healthcare and related sectors. Although research on burnout has grown rapidly, the evidence base remains fragmented, limiting understanding of cross-population patterns, measurement approaches, and the effectiveness of interventions.

OBJECTIVE: This scoping review systematically maps and synthesizes the existing literature on burnout among healthcare workers, students, teachers, night shift workers, and other professional populations, with particular emphasis on its implications for staff well-being and quality of care.

METHODS: Following Arksey and O'Malley's framework and PRISMA-ScR guidelines, systematic searches were conducted in MEDLINE, Embase, PsycINFO, CINAHL, Scopus, Web of Science, and Cochrane from inception to December 2024. Eligible studies used validated instruments to assess burnout. Data synthesis employed narrative thematic analysis and systematic literature mapping.

RESULTS: Sixty-five studies were included (healthcare workers n=29; students n=18; teachers n=9; night shift workers n=6; other populations n=3). Six key themes emerged: prevalence variations (25-72%), with healthcare workers demonstrating the highest rates (35-68%) and strongest associations with compromised patient safety; diversity of measurement tools; intervention effectiveness patterns, wherein combined individual-organizational approaches demonstrated superiority over single-component strategies (effect size d=0.67, 95% CI: 0.42-0.91 at 12-month follow-up); organizational versus individual risk factors; temporal trends including COVID-19 impacts; and implementation challenges. Methodological heterogeneity limited cross-population comparability and the standardization of interventions.

CONCLUSION: Burnout represents a critical occupational health and patient safety concern. This scoping review highlights significant gaps in cross-population research, the need for standardized measurement approaches, and the importance of multilevel, evidence-based interventions. The findings provide essential insights for researchers, healthcare administrators, and policymakers aiming to design sustainable strategies to protect staff wellbeing and ensure safe, high-quality care.},

abstract = {BACKGROUND: The management of persistent symptoms for long COVID (eg, fatigue, concentration difficulties, sleep difficulties, loss of appetite and taste, depression, and anxiety) has not been widely studied among adolescents and young adults (AYA). This systematic review and meta-analysis aimed to synthesise and review evidence on the effectiveness of non-pharmacological interventions for AYA aged 13-25 years, presenting with long COVID symptoms.

METHODS: A systematic literature search was conducted in four electronic databases (PubMed, EMBASE, PsycInfo, and ProQuest) in addition to manual searches for studies from January 2020 to May 2025 (PROSPERO: CRD42024516016). The studies were screened for eligibility, and methodological quality was assessed using the Joanne Briggs Institute Critical Appraisal tool by two independent reviewers. Findings were summarised using a narrative synthesis approach, and where possible, a meta-analysis was conducted using a random effects model with standardised mean differences (SMD) and a 95% confidence interval (CI).

RESULTS: Of the 325 screened articles, seven studies were included, which discussed six interventions. Three studies reported on the effectiveness of three multidisciplinary rehabilitation programs (eg, neuropsychological rehabilitation program, multidisciplinary post-COVID rehabilitation program, micro-choice-based concentrated group rehabilitation), three on alternative medicine practices (eg, forest bathing, traditional Thai Medicine), and one on mechanical therapy (eg, enhanced external counterpulsation). Findings suggested that interventions, although varied in duration and follow-up, were effective in improving mental health (SMD: 0.64, 95%, p<0.0497). There were also non-statistical improvements in fatigue (SMD: 1.74, 95%, p = 0.1307), quality of life (SMD: -1.34, 95%, p = 0.2787), and cognitive function (SMD: 1.05, p = 0.2989).

CONCLUSION: This review's findings suggest that non-pharmacological interventions may effectively treat neuropsychiatric symptoms of long COVID in AYA, ensuring better outcomes. Nevertheless, further research must be conducted with longer-term follow-up and robust methodology to explore sustained benefits, which may better inform treatment decisions.

These effects are attributed to the rich profile of polyphenolic compounds, which confer potent antioxidant and anti-inflammatory properties. Viral infections frequently induce oxidative stress, inflammation, and immune dysregulation, thereby posing substantial challenges to global public health. Accordingly, the development of effective antiviral agents applicable across diverse viral outbreak settings remains a critical goal. PYC has demonstrated antioxidant, anti-inflammatory, and antiviral potential against several viruses, including hepatitis C virus, dengue virus, and severe acute respiratory syndrome coronavirus 2. In addition, PYC exhibited anticancer activity by modulating cell signaling pathways, inhibiting tumor cell proliferation, inducing apoptosis, and suppressing angiogenesis. However, further research and clinical validation are required to confirm its therapeutic applications. Accordingly, this review summarizes the current understanding regarding the antioxidant, anti-inflammatory, and anticancer mechanisms of PYC. Moreover, the review highlights its immunomodulatory properties to inform future antiviral and anticancer drug development and therapeutic strategies.},

abstract = {BACKGROUND: There is a severe shortage of healthcare professionals, emphasized in a stark manner by the recent COVID-19 pandemic, where the mortality rate was primarily a consequence of medical professionals lacking the technical know-how for conducting specialized procedures. Therefore, this systematic review and meta-analysis aimed to evaluate the success rates of nurse-performed emergency surgeries, focusing on trauma care (e.g., cricothyrotomy), rural obstetric emergencies (e.g., caesarean section, hysterectomy), and general procedures (e.g., laparotomy, appendectomy).

METHODS: A systematic search was conducted across eight major databases (PubMed, Embase, CINAHL, Scopus, Web of Science, PsycINFO, Cochrane Library, ProQuest) following PRISMA guidelines. Four eligible studies were identified, and data were pooled using a fixed-effects model.

RESULTS: The synthesis of data across the four selected studies revealed a pooled relative risk (RR) of 0.88 (95% CI: 0.78, 1.00) and odds ratio (OR) of 0.80 (95% CI: 0.65, 0.99) about the efficacy in emergency surgeries conducted by nurses. These four studies were the only ones meeting our strict inclusion criteria of reporting outcome data on nurse-performed emergency procedures. An analysis of heterogeneity demonstrated minimal variability among the studies, with a Chi[2] value of 1.54, df = 3, P = 0.67, and I[2] = 0%. The test for overall effect yielded a statistically significant Z statistic of 2.03 (P = 0.04), indicating a meaningful finding. The observed inferences also showed that the surgical procedures exhibited minimal complications.

CONCLUSION: This study suggests that trained nurses can safely and effectively perform selected emergency surgical procedures. While encouraging, the limited number of studies highlights the need for further research to confirm these findings and guide clinical practice.},

abstract = {Priestia megaterium (formerly Bacillus megaterium) is a Gram-positive, spore-forming environmental bacillus rarely associated with human infection. In this report, we present a case of a rapidly progressive polymicrobial pyogenic liver abscess with subsequent isolation of P. megaterium in a 69-year-old woman with type II diabetes mellitus, chronic kidney disease, metabolic liver disease, and extensive antibiotic allergies. She initially presented with progressive abdominal pain and fever, with negative early imaging studies. Three weeks later, computed tomography (CT) demonstrated new hepatic abscesses. Interventional radiology drainage cultures initially grew Streptococcus intermedius, guiding targeted antimicrobial therapy; however, the patient clinically deteriorated with recurrent abscess formation despite drainage and broad-spectrum coverage. Subsequent aspirate cultures from the abscess fluid later grew P. megaterium, though this result was finalized after the patient's death on day 12 of admission despite intensive care and source control attempts. This case suggests that P. megaterium, traditionally regarded as nonpathogenic, may be recovered in severe infections in immunocompromised hosts; however, alternative explanations-including polymicrobial infection, antibiotic-mediated suppression of co-pathogens, iatrogenic introduction during drainage procedures, or culture contamination-must be carefully considered. Contributing factors likely included her underlying comorbidities, concurrent COVID-19 infection, delayed pathogen identification, and restrictions imposed by multiple drug allergies. Diagnostic challenges underscore the importance of repeated culture sampling, careful interpretation of microbiology results, and awareness of rare organisms when standard therapy is unsuccessful. This report expands the spectrum of diseases associated with P. megaterium. It emphasizes the need for multidisciplinary collaboration and heightened clinical vigilance in cases of rapidly progressive intra-abdominal infections that are unresponsive to conventional treatment.},

abstract = {INTRODUCTION: Isolated low forced expiratory volume in one second (FEV1) spirometric impairment (ILFSI) is characterized by a decreased FEV1 while both forced vital capacity (FVC) and the FEV1/FVC ratio remain within normal ranges. This pattern may hide an underlying respiratory disorder that warrants further examination. Notably, the 2022 European respiratory society/American thoracic society (2022-ERS/ATS) guidelines do not classify ILFSI as pathological, a stance that has sparked some controversy. This teaching report discussed the case of a woman with ILFSI who developed mild bronchial hyperreactivity after undergoing a methacholine bronchial challenge test (MBCT) and exhibited positive skin prick tests (SPTs) for dust mites.

OBSERVATION: A 28-year-old professional interior designer, who has no history of smoking or exposure to wood smoke and allergens, and who previously experienced a mild case of coronavirus disease-2019, consulted a pulmonologist for chronic cough, sputum production, and recurrent sneezing episodes. Asthma was suspected, leading to the performance of SPTs, spirometry, and either a bronchodilator test (in case of an obstructive ventilatory impairment) or MBCT (in case of a normal spirometry) as requested in the pulmonologist referral letter. The spirometry results indicated ILFSI, with a low FEV1 (z-score = -1.74, 79%) while FVC (z-score = -0.97, 88%) and the FEV1/FVC ratio (z-score = -1.35) remained normal. According to the 2022-ERS/ATS guidelines, these findings are considered normal spirometry because of the maintained FVC and FEV1/FVC ratio. The MBCT confirmed mild bronchial hyperreactivity, showing a 20% drop in FEV1 at a dose of 96 µg. Furthermore, SPTs were positive for dust mites (Dermatophagoides pteronyssinus and farinae).

CONCLUSION: The results of this report suggested a possible association between ILFSI and early allergic asthma, indicating that ILFSI should be re-examined in future revisions of the 2022-ERS/ATS guidelines for interpreting spirometric tests.},

This review provides a comprehensive analysis of drug repurposing efforts targeting major viral infections between 2020 and 2025, with a particular focus on clinical trials and intervention strategies. The background and growing significance of drug repurposing are discussed in the context of the urgent global demand for accelerated antiviral development. Key viral infections, including SARS-CoV-2, monkey pox virus, H1N1 influenza, dengue virus, Zika virus, and hepatitis B and C, are examined in detail, with an emphasis on therapeutic interventions and clinical trial outcomes. Tabulated data summarize the efficacy, target mechanisms, and trial phases of key repurposed drugs. Additionally, the integration of emerging technologies, particularly artificial intelligence and machine learning, has enhanced the identification of novel drug-virus interactions, thereby increasing the precision of repurposing strategies. The paradigm shift toward host-targeted therapies further offers an alternative approach by disrupting host factors essential for viral replication. Despite significant progress, clinical challenges such as drug resistance, dosing optimization, and safety concerns persist. Overall, this review underscores the evolving role of repurposed drugs as a strategic asset in combating current and future viral pandemics through an integrated, evidence-based framework. Unlike many prior reviews that focus on single pathogens or early in silico candidate lists, we (i) benchmarked computational predictions against Phase II–IV clinical outcomes and real-world evidence, (ii) compared host-directed versus virus-directed repurposing strategies across multiple viral families, and (iii) integrated organ-specific toxicity constraints to explain translational attrition and guide future trial design.},

abstract = {Viral proteases are central targets in antiviral drug discovery and development because they play essential roles in viral replication and maturation. Although protease inhibitors have achieved major clinical success, traditional design strategies face challenges, including resistance development, poor oral exposure of early peptidomimetics, and off-target toxicity of highly reactive covalent warheads. Classical approaches, such as peptidomimetics, macrocyclization, and covalent warhead engineering, are discussed alongside contemporary strategies, including allosteric modulation and targeted protease degradation via proteolysis-targeting chimeras (PROTAC) technology. Particular emphasis is placed on how these strategies address key obstacles, such as resistance evolution, selectivity, metabolic stability, and oral bioavailability. Several quantitative case studies have also demonstrated the growing significance of computational tools in contemporary antiviral discovery. For SARS-CoV-2 main protease (Mpro), these workflows were enabled by the rapid availability of high-resolution experimental crystal structures of the target protein. The evolution of a weak fragment (Kd ≈ 1.7 mM; ΔG ≈ -3.6 kcal/mol) into a covalent inhibitor (QUB-00006-Int-07) with enzymatic inhibition (IC50 ≈ 830 nM) was successfully guided by molecular dynamics (MD) simulations and absolute binding free energy calculations. This was subsequently confirmed experimentally using NMR, ESI-MS, and FRET assays. Furthermore, out of 25 computationally prioritized candidates with Ki values less than 4 μM, 15 active Mpro inhibitors were identified using accelerated free-energy perturbation-based repurposing campaigns. Long-range allosteric pathways connecting the catalytic site to resistance-associated regions and experimentally verified allosteric pockets have also been discovered using dynamic nonequilibrium MD. Together, these integrated in silico approaches enable the early prioritization of high-affinity ligands, mechanistic understanding of resistance, and significant reduction of late-stage attrition in antiviral drug discovery. Through detailed case studies on SARS-CoV-2 main protease (Mpro), Zika virus NS2B-NS3 protease, and Dengue virus NS2B-NS3 protease, the review illustrates how medicinal chemistry principles translate molecular insights into clinically relevant antivirals. Finally, a forward-looking development roadmap is proposed that integrates potency, selectivity, pharmacokinetics, manufacturability, and resistance management toward the goal of broad-spectrum, durable, and adaptable protease-targeted therapeutics development.},

abstract = {Musculoskeletal anatomy is a critical component of allied health curricula. With the ubiquity of technology in the classroom and the recent COVID-19 pandemic creating accessibility barriers for students, there is a need for viable digital resources to enhance learning by supplementing traditional textbook studying. This article describes the creation of an annotated, interactive, three-dimensional digital model and presents preliminary data on its effectiveness for students learning musculoskeletal structures of the hip and knee for the first time. The 3D model was developed in Blender using open-source files and was uploaded to the Sketchfab platform. Eighty-one students in the musculoskeletal anatomy course at a large midwestern university took an assessment to measure their baseline anatomical knowledge, studied the testable structures from either the model or textbook images for 10 min, and took a follow-up assessment. Students in the 3D Model Group saw greater increases from their baseline scores and also reported higher confidence in what they had learned, increased ability to visualize anatomical structures, and greater enjoyment of their resource than students who used textbook images. The findings presented here suggest that creating effective, accessible 3D digital resources is feasible for educators without training in technology-related fields and that having access to these resources can be beneficial to first-time learners of anatomy.},

abstract = {BACKGROUND: Non-pharmaceutical interventions (NPIs) are central to mitigating COVID-19 and influenza, yet comparative economic evaluations remain scarce. This systematic review assessed the cost effectiveness and reporting quality of NPI evaluations across both diseases. The study was registered with PROSPERO (CRD42024552613).

METHODS: Following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, we searched five medical (PubMed, Scopus, EMBASE, CINAHL, and EconLit) and four health technology assessment databases (NHS HTA, CRD DARE, NHS EED, and INAHTA) up to December 2025, including only full economic evaluations. The search strategy incorporated four domains-'influenza,' 'COVID-19,' 'NPIs,' and 'economic evaluation'-and was guided by the WHO NPI framework, encompassing five domains: personal protective, environmental, physical distancing, travel-related, and educational measures. Reporting quality was assessed using the Consolidated Health Economic Evaluation Reporting Standards 2022 (CHEERS 2022) checklist.

RESULTS: Thirty-three studies (13 influenza, 20 COVID-19), predominantly from high-income countries, were included. School closures, the most frequently evaluated NPI, were generally not cost effective except during severe pandemics or bundled with other measures. Workforce and business closures were cost effective only in high-severity influenza, with inconsistent findings for COVID-19. Social distancing was cost effective for COVID-19 but not for H1N1 influenza. Isolation, lockdowns, and travel restrictions were cost effective only when implemented early. Face masks and hand hygiene, assessed solely for COVID-19, were generally cost effective when implemented alongside other measures. The median CHEERS score was 75.0%, with one study rated excellent.

CONCLUSION: Our review highlights heterogeneity in cost effectiveness by pandemic severity, intervention type, bundling of measures, and timing. Strategies that combined low-cost NPIs like masks or hand hygiene demonstrated better value, while socially disruptive measures like school and business closure incurred high costs with inconsistent cost-effectiveness outcomes. Integration with vaccines or antivirals further enhanced cost effectiveness. Evidence gaps include the scarcity of evaluations from low-resource settings and variability in country-specific value thresholds. Addressing these gaps is essential for guiding efficient and cost-effective pandemic preparedness.},

Placental pathology is characterised mainly by maternal vascular malperfusion and inflammation, with limited evidence of direct viral infection. Maternal vaccination-particularly with mRNA vaccines-induces robust IgG responses with efficient transplacental and lactational transfer, conferring passive neonatal protection.

abstract = {BACKGROUND: Non-tuberculous mycobacteria (NTM) are increasingly recognized as significant pathogens causing pulmonary and extrapulmonary diseases worldwide, including Russia. Despite a rising incidence, comprehensive data on the geographic distribution and species diversity of NTM across Russia remain limited. This study aims to analyze the prevalence and NTM species diversity in various Russian regions, highlighting regional variability and diagnostic challenges.

METHODS: A systematic review and analysis of published data and regional studies on NTM detection in different regions of Russia from 2010 to 2024 were conducted. Identification methods included GenoType Mycobacterium CM/AS assays, PCR, mass spectrometry (MALDI-TOF MS) and whole-genome sequencing. Data from multiple regions, including Moscow, Saint Petersburg, the Siberian Federal District and others, were analyzed to assess species diversity and epidemiological patterns.

RESULTS: The species spectrum of NTM in Russia is broad and heterogeneous. M. avium is the predominant species with an average frequency of 30-40%. A secondary group, including M. gordonae (13-25%) and M. intracellulare (12-20%), demonstrates significant prevalence. The remaining species, such as M. fortuitum, M. lentiflavum, M. kansasii, and M. abscessus, exhibit lower but notable frequencies ranging from 3% to 20%. Other species such as M. malmoense, M. xenopi, M. simiae etc. were less common, with frequencies below 5%. Regional differences in species prevalence were pronounced, with M. avium-intracellulare complex dominating in many areas reaching more than 50% of all NTM, while species like M. lentiflavum were more common in specific regions such as the Republic of Komi (44% of all NTM in the region). The COVID-19 pandemic (2020-2023) impacted epidemiological surveillance but did not substantially alter species diversity. Advanced molecular techniques, including whole-genome sequencing, revealed subspecies-level diversity, notably among M. avium and M. abscessus complexes.

CONCLUSIONS: This study underscores the significant geographic variability and species diversity of NTM in the Russian Federation. The detection rates and species spectrum depend on the diagnostic methods employed, highlighting the need for standardized, advanced molecular diagnostics. Continued surveillance and molecular characterization are crucial for improving diagnosis, guiding therapy, and understanding the epidemiology of NTM infections in Russia.},

In fact, preceding this article, I had published in the Japanese Journal of Aerosol Science a companion review with this, titled "An Introduction to Aerosol Virology"1）, which included basic virological knowledge for members less familiar with viruses, aiming to spark their interest in the field. To advance "aerosol virology", it is necessary to approach research goals with knowledge of both aerosol science and virology, not just one field. This represents a largely unexplored frontier even for virology. I hope members of the Virology Society will venture into this frontier. Both reviews were written with this aspiration in mind.},

abstract = {OBJECTIVE: This scoping review examined available evidence in implementation and evaluation of virtual care in Canada. Virtual care saw recent uptake due to the COVID-19 pandemic; however, to ensure quality of care, rigorous implementation and evaluation frameworks are needed.

METHODS: Peer-reviewed and gray literature were searched to determine extent, range, and nature of evidence surrounding implementation and evaluation of virtual care based on the guidelines of the Joanna Briggs Institute. Although virtual care can encompass synchronous and asynchronous modalities, this review focused on synchronous virtual care, defined as real-time interactions between patients and providers via videoconferencing or telephone. Search included MEDLINE, EMBASE, Psych Info, and CINAHL databases and national and provincial health system, professional organization, and regulatory websites. Inclusion criteria included videoconferencing or telephone and English and French Canadian sources. Citations were screened by two researchers at title, abstract, and full-text levels.

RESULTS: Two hundred and eight (208) manuscripts were included for analysis. High numbers of studies on patient satisfaction, process outcomes, and barriers were identified, with underrepresentation of health and systems outcomes and impact evaluations. There were very few studies examining hybrid care, planetary health, and use of virtual care with equity-deserving groups.

DISCUSSION: This scoping review identified areas of importance for future research, including the use of virtual care in rural and remote regions, inpatient, long-term, and emergency settings, hybrid care, economic and planetary health impacts, and artificial intelligence. As well, enhancing standardization of implementation and evaluation guidelines will optimize quality of care and best practice.},

abstract = {The COVID-19 pandemic has left lasting health consequences that extend beyond the acute infection phase, with long COVID emerging as a complex multisystem condition that poses significant challenges in the perioperative setting. Patients with post-infectious respiratory or cardiovascular sequelae present an increased anesthetic risk due to persistent inflammation, pulmonary fibrosis, reduced lung compliance, and myocardial dysfunction. These alterations predispose to hypoxemia, arrhythmias, and hemodynamic instability during surgery, making preoperative assessment and individualized anesthetic planning essential. Comprehensive evaluation, including functional tests, cardiac and pulmonary imaging, and laboratory analysis, allows early identification of residual organ dysfunction that can compromise perioperative safety. Anesthetic management must be adapted to the patient's physiological condition, emphasizing lung-protective ventilation, cautious fluid therapy, and close hemodynamic monitoring. Regional anesthesia is preferred when feasible to minimize airway manipulation and reduce respiratory complications, while total intravenous anesthesia represents a safer option when general anesthesia is required. Postoperative care focuses on extended respiratory monitoring, multimodal analgesia to limit opioid use, and the implementation of pulmonary physiotherapy and antithrombotic prophylaxis to prevent complications. Psychological support is also recommended to address post-COVID anxiety and fatigue, contributing to holistic recovery. Although clinical guidelines provide useful recommendations, current evidence remains limited and heterogeneous. Further research is required to clarify the pathophysiological mechanisms of long COVID, evaluate anesthetic drug interactions, and develop validated risk stratification tools. Establishing standardized, evidence-based perioperative protocols is essential to improve outcomes and ensure patient safety in individuals with long COVID undergoing emergency surgery.},

Analysis of multi-year surveillance data across hemispheres reveals that severe acute respiratory syndrome coronavirus-2 exhibits seasonal divergence, with consistent summer surges in tropical regions, such as India, and winter peaks in temperate climates. We propose that this pattern arises primarily from human (host) behavioural responses to multi-animal tropism to climatic (environment) extremes, which recreate high-risk indoor transmission settings under both heat and cold. Unlike influenza, severe acute respiratory syndrome coronavirus-2 (agent) combines thermal resilience, broad tissue tropism, and efficient pre-symptomatic transmission, allowing persistence beyond classical winter bounds. Recognizing coronavirus disease 2019 as a behaviourally modulated (through agent-host-environment triad) seasonal virus may help tailor regional surveillance, ventilation, and vaccination strategies in an era of accelerating climatic change.},

The literature was identified through focused searches of PubMed and Scopus, prioritizing human studies and late-stage preclinical data published between 2000 and 2025. We outline the key mucosal immune correlates required to block viral entry at the airway epithelium, including secretory IgA and tissue-resident memory T cells, and review advances across major vaccine platforms. Current clinical experience with coronavirus disease 2019, influenza, and RSV mucosal vaccines is discussed, along with challenges related to immune measurement, delivery optimization, evaluation of transmission outcomes, and scalable global implementation, including heterologous systemic-mucosal prime-boost strategies. Overall, accumulating evidence positions mucosal vaccination as a promising complement to IM vaccines, with the potential to shift respiratory virus control from disease mitigation to prevention of infection and transmission.},

The trigger is context-dependent: Mycobacterial antigens in tuberculosis-endemic areas; staphylococcal eyelid disease and rosacea in high-income areas. Although classically bacterial-driven, virus-associated presentations like herpes simplex virus (HSV)-linked phlyctenular disease, pediatric PKC during acute coronavirus disease 2019 (COVID-19) infection, and molluscum contagiosum-driven keratoconjunctivitis suggest the same antigen-mediated pathway. Photophobia and discomfort are prevalent, and corneal involvement can cause neovascularization, scarring, amblyopia, and perforation. This minireview combines epidemiologic, clinical, and immunopathologic data to identify causes and update care. Practical takeaways: (1) Treat the antigen source (blepharitis/rosacea, chlamydia, parasites) and screen for tuberculosis when risk factors exist. Consider viral triggers when history or exam suggest HSV, recent COVID-19, or eyelid molluscum; (2) Suppress inflammation promptly with a short, carefully tapered course of topical corticosteroids; (3) Use topical cyclosporine as a steroid-sparing agent in recurrent or steroid-dependent disease; and (4) Reduce antigen load with lid hygiene and targeted antimicrobials. Start antitubercular treatment for tuberculosis. If a viral cause is anticipated, add antiviral medication or molluscum lesion eradication to the steroid-sparing regimen. Trigger-focused, steroid-sparing treatment reduces recurrences, vision-threatening consequences, and steroid exposure.},

This International Consensus aims to critically evaluate the role of vitamin D in gastrointestinal homeostasis, infection prevention, and immune regulation. A multidisciplinary panel of experts conducted a comprehensive review of the literature, distinguishing between associative evidence from observational studies and causal inferences derived from interventional trials addressing gut barrier integrity, dysbiosis, intestinal cancer prevention, respiratory infections, and autoimmune diseases. While vitamin D deficiency has been consistently associated with alterations in gut microbiota composition, increased intestinal permeability, impaired immune tolerance, and increased susceptibility to infections and autoimmune conditions, evidence from interventional studies remains more variable. Clinical outcomes are influenced by baseline 25(OH)D status, supplementation dose and formulation, timing of intervention, and disease context. Vitamin D supplementation has shown potential benefits in selected settings (i.e., autoimmune diseases and acute respiratory infections), and particularly in cases of documented deficiency. Given its pleiotropic role and favourable safety profile, appropriate screening and optimization of vitamin D represent a low-cost and potentially impactful strategy to support gut barrier function and immune competence. While further research is needed to define these therapeutic applications, maintaining vitamin D concentrations above 20 or 30 ng/mL in individuals at skeletal or immunological risk emerges as a reasonable clinical target. This Consensus Panel supports the integration of vitamin D assessment and correction into routine care for at-risk populations and calls for greater awareness of its extra-skeletal relevance.},

abstract = {BACKGROUND: Childhood and adolescent vaccination is a cornerstone of public health, yet coverage has stagnated or declined in several regions, partly due to vaccine hesitancy. Schools offer a unique setting to promote vaccination by reaching children and adolescents during formative years. This systematic review and meta-analysis aimed to synthesize evidence on the effectiveness of school-based health education interventions in improving vaccine-related knowledge, attitudes, intentions, and uptake.

METHODS: Following PRISMA guidelines, we searched six databases up to August 2024 for interventional studies evaluating school-based educational programmes targeting students aged 6-18 years. Randomized controlled trials and quasi-experimental studies assessing outcomes related to vaccine knowledge, attitudes, intention to vaccinate, or uptake were included. Studies focusing on COVID-19 vaccination were excluded. Risk of bias was assessed using validated tools. A random-effects meta-analysis was conducted for HPV vaccination uptake.

RESULTS: Thirty-eight studies (1985-2024) were included: 9 RCTs/cluster-RCTs, 14 controlled quasi-experimental studies, and 15 pre-post studies. HPV vaccination was the most frequently studied vaccine (26/38). Most interventions significantly improved vaccine knowledge, while effects on attitudes and intention were less consistent. Eleven studies assessed vaccine uptake, with most reporting post-intervention increases. Meta-analysis of randomized trials showed a significant effect on HPV uptake (RR 4.18, 95% CI 1.41-12.37), although heterogeneity was high and methodological quality varied.

CONCLUSIONS: School-based health education appears to improve vaccine knowledge and may contribute to increased uptake, particularly for HPV. However, evidence is limited by heterogeneity and risk of bias. More rigorous, theory-informed, and sustainable whole-school approaches are needed.},

abstract = {BACKGROUND: Vaccine trust is essential for achieving high coverage rates and sustaining immunization programs worldwide. However, hesitancy intensified by the COVID-19 pandemic and the spread of misinformation has challenged trust in vaccines, healthcare professionals, and institutions. This scoping review maps global evidence on the determinants, challenges, and strategies to strengthen vaccine trust.

METHOD: The review followed the JBI Brazilian Centre for Evidence-Based Health Care methodology and the PRISMA-ScR guidelines, with a protocol registered on the Open Science Framework. Searches were conducted in seven databases and additional sources. Studies that directly addressed vaccine trust in any population were included. Data extraction and analysis combined descriptive statistics with narrative synthesis.

RESULTS: A total of 66 studies published between 2020 and 2024 were included, most of them conducted in the United States and focused on COVID-19. Vaccine trust was found to be influenced by perceptions of safety and effectiveness, trust in health systems, professionals, and institutions, as well as individual beliefs and cultural factors. The pandemic increased uncertainty but also encouraged new strategies for community engagement. Health literacy and the involvement of trusted professionals were identified as key elements in strengthening trust. Evidence gaps remain concerning groups such as adolescents, older adults, migrants, and populations in vulnerable situations. Several measurement instruments were mapped, but standardization remains limited.

CONCLUSION: Vaccine trust is a complex and context-dependent phenomenon. Strengthening it requires clear communication, context-specific strategies, active community engagement, and the involvement of healthcare professionals as trusted sources. Future research should include understudied populations, use validated instruments, and assess trust-building interventions to inform more equitable and effective immunization policies.},

abstract = {The post-COVID pandemic era has witnessed a concerning resurgence of respiratory viruses, driving a global increase in acute respiratory infections. This trend may stem from relaxed non-pharmaceutical interventions, waning herd immunity, immunological imprinting limiting heterosubtypic protection, or viral antigenic evolution. This review aims to identify and characterize risk and protective factors associated with infection, hospitalization, severe illness, and mortality, while elucidating the drivers of the rising incidence of respiratory virus infections post-pandemic. Evidence on SARS-CoV-2 sublineages, influenza, respiratory syncytial virus, rhinovirus, adenovirus, human metapneumovirus, human parainfluenza virus, human coronaviruses, and cytomegalovirus has been collected and identified. Identified risk factors include demographic characteristics such as pediatrics and older age, male sex, race (Black, Hispanic, American Indian or Alaska native), preterm birth, and HLA-DQA1, IFNAR2, ST6GAL, and B3GALT5 genetic susceptibility. Behavioral, socioeconomic (low socioeconomic status, crowded living conditions), environmental influences (cold seasons, pollution), smoking, obesity and malnutrition could also exacerbate the risk of infection and adverse outcomes. Comorbidities, such as chronic conditions and immunocompromised states, significantly increase the risk of severe disease and hospitalization. Laboratory indices linked to severe disease outcomes include neutrophilia or neutropenia, lymphopenia, eosinopenia, and elevated C-reactive protein. Viral subtypes, viral load kinetics, vaccination status, and antiviral therapies further delineate risk profiles. Epithelial barrier impairment and underlying chronic airway diseases characterized by type 2 immunity also play a detrimental role in the development and severity of respiratory viral infections. Our findings highlight the need for stratified prevention strategies, which combine universal measures targeting shared determinants with virus-specific interventions addressing unique virological and transmission dynamics. It will provide a critical framework for optimizing precision public health strategies to counter repeated respiratory threats in the evolving post-COVID-19 pandemic landscape.},

abstract = {BACKGROUND: The COVID-19 pandemic has significantly impacted cancer care services in the United Kingdom (UK), potentially exacerbating pre-existing health inequalities. While emerging studies have documented service disruptions, a comprehensive synthesis of how these disruptions have widened disparities remains absent. This systematic review examines the extent to which the pandemic disrupted the cancer care pathway and intensified existing disparities across the UK, identifying key sociodemographic and geographical factors influencing access to services. METHODS: A systematic search of PubMed, Scopus, and CINAHL was conducted for studies published between January 2020 and October 2024. Eligible studies included observational and empirical research examining disparities in cancer screening, diagnosis, treatment, and outcomes during the COVID-19 pandemic, as well as the corresponding mitigation strategies. Data extraction followed a structured approach using a custom-developed extraction form designed for this review. Study quality was appraised using a bespoke scoring system, classifying studies as high, moderate, or low importance. Narrative synthesis, following the framework outlined by Popay et al., was then employed to identify key themes and explore relationships between findings. RESULTS: 30 out of 457 studies met the inclusion criteria. The review found that socioeconomic status (SES) emerged as the most significant determinant, with individuals from deprived areas experiencing greater barriers to screening, urgent referrals, and treatment access, leading to poorer patient outcomes. Ethnic minorities, particularly Black patients, faced disproportionate reductions in hospital admissions and cancer screening participation. Age-related disparities were also evident, as older adults maintained higher screening rates but faced greater COVID-19 risks, while younger adults from lower-income backgrounds encountered delays in diagnosis and treatment. CONCLUSIONS: The review highlights that the COVID-19 pandemic has exacerbated existing inequalities in UK cancer care, with SES, ethnicity, and age emerging as key determinants. Targeted interventions are essential, including the establishment of COVID-free “cold sites”, deployment of mobile screening units, and culturally tailored outreach programmes for ethnic minority communities. Strengthening regional healthcare capacity and conducting longitudinal assessments will be crucial in addressing disparities and ensuring equitable cancer care. Future research should focus on the long-term consequences of these disruptions on cancer outcomes and healthcare resilience.

This review examines the multifactorial mechanisms underlying these metabolic complications, including activation of the immune system and inflammatory cascades, lifestyle changes, nutritional deficiencies, imbalances in amino acid metabolism, alterations in ketogenesis, disruptions in the gut microbiome, psychological impacts, and COVID-19 vaccines. We discuss how these factors collectively contribute to insulin resistance, particularly in the context of COVID-19, and highlight potential therapeutic strategies, such as dietary interventions and ACE2 activators, that may mitigate these effects. Our analysis underscores the need for targeted approaches to prevent and treat insulin resistance in post-COVID-19 patients, emphasizing the importance of understanding the pandemic's long-term metabolic consequences.},

abstract = {INTRODUCTION: Despite the presence of "COVID-19-related social stigma" in health literature, there is no clear definition of this concept in healthcare setting. It is often confused with related terms such as shame, discrimination, and prejudice, leading to imprecise research questions and ineffective evaluations. The aim of this study was to elucidate the concept of social stigma associated with COVID-19 in healthcare workers using Rodgers' evolutionary concept analysis method.

METHODS: Rodgers' evolutionary method of concept analysis was employed to clarify COVID-19-related social stigma in healthcare workers. A literature review was conducted using key terms "COVID-19", "social stigma", and related terms in PubMed, Scopus, Cochrane, ProQuest databases, and Google Scholar from January 2019 to September 2024. Among 3993 studies found, 46 were selected for analysis. Data were analyzed using thematic analysis.

RESULTS: COVID-19-related social stigma among healthcare workers is a multidimensional concept characterized by three primary attributes: Alienation, Humiliation, and Ignorance. The antecedents identified include Fear, Fake news, and the Contagious Nature of the virus. Consequences of this stigma encompass Psychological Issues, Feelings of Worthlessness, Impaired Functionality, and Job Attrition.

CONCLUSION: Social stigmatization associated with COVID-19 exerts significant pressure on healthcare workers. It is crucial to understand the factors that exacerbate this issue. Identifying the dimensions of this stigma can provide valuable insights for policymakers and the media. The implementation of preventive measures, such as clear protocols tailored to the public's educational level and addressing fears of contamination, can improve the situation and reduce the financial strain caused by the loss of healthcare personnel, ultimately enhancing the quality of care.},

abstract = {Type II alveolar epithelial cells (AEC2s) maintain surfactant homeostasis, support distal-lung repair, and contribute to antiviral innate defense. Influenza A virus (IAV), SARS-CoV-2, and respiratory syncytial virus (RSV) use distinct entry receptors, yet severe disease is repeatedly marked by AEC2 dysfunction, alveolar barrier failure, and dysregulated inflammation. We synthesize cross-virus evidence for convergence on a small set of host hubs: innate sensing and interferon signaling, mitochondria-centered immunometabolism and oxidative stress, post-translational signaling modules, barrier and surfactant programs, and regulated cell-death checkpoints. We summarize structural and post-translational mechanisms by which viral proteins disrupt pattern recognition receptor (PRR)-mitochondrial antiviral signaling protein (MAVS) signaling, couple mitochondrial injury to weakened antiviral responses, and bias epithelial fate toward inflammatory lytic injury. Where AEC2-specific evidence is incomplete, especially for integrated PANoptosis-like programs, we label these elements as working models and highlight validation needs. We compare model systems used to study AEC2 infection, including ALI cultures, organoids, lung-on-chip platforms, and single-cell or network analyses. Finally, we discuss host-directed therapeutic opportunities along the cascade, separating near-term approaches from longer-term platform strategies such as targeted protein degradation and targeted nanodelivery, and noting constraints in distal-lung delivery, onset kinetics, and safety. This AEC2-centered convergence framework supports mechanism-driven interpretation of severe viral pneumonia and guides broader-spectrum intervention concepts.},

As workplaces advance toward technologically mediated environments, including avatar-based systems for remote interaction, understanding the health implications of teleworking is crucial for future occupational health standards.ObjectiveThis review examined the health-related outcomes of teleworking during the pandemic, comparing Japan and other countries to inform health-supportive remote work systems.MethodsA structured narrative review was conducted using MEDLINE (PubMed) and IEEE Xplore through January 9, 2026. Studies were included if they examined teleworking in adult workplace environments and reported physical, mental, behavioral, or performance-related outcomes. Data from 67 eligible studies (12 from Japan and 55 from other countries) were analyzed for the physical health, mental health, lifestyle factors, and work performance domains. Cultural and institutional factors were examined to understand the regional differences.ResultsTelework has been linked to musculoskeletal discomfort, sedentary behavior, psychological stress, and unhealthy lifestyle choices. Japanese and international studies have identified these challenges, although the manifestations vary by context. In Japan, inflexible teleworking, inadequate home infrastructure, and an office-centric culture exacerbate negative outcomes, particularly for women and caregivers. International studies have highlighted the benefits of flexible scheduling and organizational support. Cultural norms and institutional readiness mediated these effects.ConclusionsThis review demonstrates the need for evidence-based health standards for next-generation remote work environments including avatar-based systems. We propose recommendations incorporating ergonomic design, health monitoring, organizational flexibility, and cultural adaptation. As remote work technologies evolve, policy frameworks must prioritize worker well-being.},
