An overview of HLA variants in COVID-19 vaccine-induced autoimmunity.

International journal of molecular epidemiology and genetics, 16(3):16-41.

COVID-19 vaccination, both in healthy individuals and those with comorbid medical disorders, has proven highly effective in mitigating critical disease progression and mortality rates. Nevertheless, although rare, induction of autoantibodies and new-onset autoimmune conditions in apparently healthy individuals receiving COVID-19 vaccination have been documented. These autoimmune phenomena can be broadly classified into organ-specific autoimmune disorders (e.g., subacute thyroiditis (SAT)) and systemic autoimmune disorders, with many being generally transient (e.g., vaccine-induced thrombotic thrombocytopenia (VITT)) and others causing chronic disability (e.g., systemic vasculitis). Recent studies have highlighted significant associations between COVID-19 vaccine-associated autoimmunity and human leukocyte antigen (HLA) loci. For example, HLA class I alleles such as HLA-B*35 and HLA-C*04 have been associated with COVID-19 vaccine-induced SAT, while HLA class II alleles, including HLA-DRB1*11:04, HLA-DQA1*05:01, HLA-DQB1*02:01, and HLA-DPB1*17:01, have been linked to VITT. This review synthesizes the reported associations between classical HLA loci and COVID-19 vaccine-induced autoimmunity, providing insights into potential mechanisms and clinical implications.

The Association of Polymyalgia Rheumatica and Giant Cell Arteritis With COVID-19 Vaccination: A Systematic Review.

Clinical medicine insights. Arthritis and musculoskeletal disorders, 19:11795441251414673.

BACKGROUND: Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are interrelated inflammatory conditions, and evidence suggests that infection and vaccination might act as a trigger for these conditions. This descriptive systematic review summarizes the published case reports and case series on new-onset PMR and GCA following COVID-19 vaccination, highlighting their clinical features, diagnostic findings, and treatment outcomes.

OBJECTIVES: To do a systematic analysis of available literature regarding the association between COVID-19 vaccination and the first onset or flare of PMR and/or GCA.

DESIGN: Systematic review of case reports and case series.

DATA SOURCES AND METHODS: A systematic literature search was conducted using PubMed/MEDLINE, Cochrane, ScienceDirect, and Google Scholar. Data on patient demographics, clinical features, outcomes, and latency periods were extracted and analyzed. Quality assessment of included studies was performed using the Joanna Briggs Institute Critical Appraisal Tool.

RESULTS: A total of 32 articles, documenting 50 new-onset cases (30 PMR and 20 GCA), were identified for inclusion. The mean age for patients with PMR was 71.06 years, and 72.85 years for GCA. A slight female predominance was observed (60%) for both PMR and GCA. Pfizer-BioNTech (48%) and AstraZeneca (38%) vaccines were most frequently associated with disease onset. The mean latency period from vaccination to symptom onset was 11.03 days for PMR and 5.3 days for GCA, indicating a temporal relationship. Most of these studies originated from North America and Europe mimicking the global scale of vaccination. Most patients responded well to symptomatic treatment with corticosteroids.

CONCLUSIONS: There exists a temporal association between COVID-19 mRNA or viral vector-based vaccines and the onset of PMR and GCA. While causality is not proven, this review underscores the need for clinicians to be aware of this potential association to ensure timely diagnosis and treatment, particularly as booster vaccinations continue to be administered. Larger epidemiological studies with long-term follow-up are essential to further explore this association.

Glossopharyngeal neuralgia after SARS-CoV-2 infection: A case report.

Journal of clinical and experimental dentistry, 17(12):e1550-e1553.

Glossopharyngeal neuralgia (GN) is a rare neuropathic disorder characterized by sudden, unilateral, electric shock-like pain in the areas innervated by the glossopharyngeal nerve. Its diagnosis is frequently delayed because of its clinical overlap with odontogenic and otorhinolaryngological conditions. In the context of the COVID-19 pandemic, different cranial neuropathies have been reported, suggesting possible post-infectious mechanisms. We describe the case of a 54-year-old male dentist, without relevant medical history, who developed recurrent episodes of intense pain in the right pharynx and base of tongue after confirmed SARS-CoV-2 infection. Symptoms were triggered by swallowing, coughing, and salivary stimulation, reaching maximum intensity on the visual analogue scale (EVA 10/10). Brain and neck magnetic resonance imaging revealed no structural abnormalities. Treatment with carbamazepine (600 mg/day) partially reduced frequency and severity of attacks, while pregabalin (300 mg/day) showed no benefit. This case highlights the need to consider SARS-CoV-2 infection as a potential trigger of GN, underscores the importance of recent infectious history in the differential diagnosis, and emphasizes the relevance of early pharmacological management in clinical improvement.

The endothelial-immunothrombotic storm in viral sepsis: lessons from COVID-19.

Frontiers in immunology, 16:1681764.

Taking COVID-19 as an illustrative example, this review systematically elucidates the central pathological mechanism of viral sepsis, termed the endothelial-immunothrombotic storm. This mechanism is initiated by the direct viral infection of endothelial cells, which provokes excessive immune activation and disrupts coagulation through immunothrombosis, including cytokine storms, NETosis, and complement activation. Meanwhile, these processes establish a vicious cycle leading to multiple organ failure. Compared with classical bacterial sepsis, viral sepsis exhibits distinctive features such as interferon dysregulation, direct endothelial damage, a hypercoagulable state, and T-cell exhaustion. This review integrates the latest research findings, contrasts the pathophysiological differences between viral and bacterial sepsis, and proposes precision strategies focused on endothelial protection, immune modulation, and anticoagulation. Finally, we discuss the clinical translational prospects of these approaches and suggests directions for future research.

Association of Particulate Matter (PM2.5) With COVID-19 Infection and Mortality in Low-and Middle-income Asian Countries: A Systematic Review and Meta-analysis.

Journal of preventive medicine and public health = Yebang Uihakhoe chi pii:jpmph.25.499 [Epub ahead of print].

OBJECTIVES: Low-and middle-income countries in Asia bear a disproportionate burden of particulate matter with an aerodynamic diameter of 2.5 micrometers or less (PM2.5) pollution, yet data remain scarce. This systematic review and meta-analysis aimed to quantify the association between PM2.5 exposure and the risks of coronavirus disease 2019 (COVID-19) infection and mortality in this vulnerable region.

METHODS: A systematic search was conducted in PubMed, Scopus, and other major databases for studies published up to December 31, 2024. We included observational studies reporting associations between PM2.5 and COVID-19 outcomes in low- and middle-income Asian countries. Pooled effect sizes and 95% confidence intervals (CIs) were calculated using a random-effects model. The study was registered with PROSPERO (CRD42022316008).

RESULTS: Fourteen studies met the inclusion criteria. Separate analyses demonstrated statistically significant positive associations between PM2.5 exposure and COVID-19 infection for both short-term exposure (pooled risk ratio [RR], 1.12; 95% CI, 1.07 to 1.18) and long-term exposure (pooled RR, 1.41; 95% CI, 1.28 to 1.56). For mortality, the analysis identified a statistically non-significant positive association with short-term exposure (pooled RR, 1.37; 95% CI, 0.80 to 2.33). Substantial heterogeneity was observed across all analyses (I² > 85%); however, sensitivity analyses confirmed that the findings for infection were robust.

CONCLUSIONS: Our findings provide robust evidence that PM2.5 exposure is a significant risk factor for COVID-19 infection in low- and middle-income Asian countries. The available evidence was insufficient to establish a clear association with mortality. These results underscore the urgent need for strengthened air quality control policies as a critical component of public health strategies to mitigate the burden of respiratory pandemics..

[Progress in research of influence of gene polymorphisms on vaccine immune response].

Zhonghua liu xing bing xue za zhi = Zhonghua liuxingbingxue zazhi, 47(1):180-186.

To introduce the recent progress in the research of gene polymorphisms and differences in vaccine immune responses, this paper systematically summarizes current findings of the associations between human leukocyte antigen (HLA) polymorphisms and other key immunoregulatory gene variations with vaccine responses across different domains, including COVID-19 and influenza vaccines. Furthermore, it discusses the impact of different genotypes on antibody production, immune protection, and the risk for breakthrough infections. To address the challenges posed by genetic polymorphisms, this paper further summarizes several key strategies for vaccine optimization, including conserved epitope targeting, multivalent vaccine design, and peptide-carrier conjugation approaches. Although genomics has laid a theoretical foundation for precise vaccine design, multiple challenges still persist in current research, such as the complexity of gene-environment interactions and ethical concerns regarding data sharing and privacy protection. Future investigations should further evaluate the effects of specific gene polymorphisms, such as detailed HLA subtypes, on the variations in vaccine immune responses, and elucidate underlying mechanisms by integrating functional studies Exploring and establishing genomics and multi-omics-based precise immunization strategies will provide more effective solutions for vaccine-preventable diseases.

Narrative Review of Opioid Use Disorder Treatment Changes During the COVID-19 Pandemic and Their Impact on American Indian/Alaska Native Communities.

Nursing open, 13(1):e70437.

BACKGROUND: The United States (US) declared drug overdose a public health emergency in 2017. Despite this, two million people reported having an opioid use disorder (OUD) in 2018. However, following the beginning of COVID-19 there was a 53% increase in overdose deaths, with American Indian/Alaska Native (AI/AN) individuals experiencing the highest rates of all racial groups. In response to the COVID-19 pandemic and OUD treatment access challenges, OUD treatment policies were changed to improving access to care.

PURPOSE: This review examines how the state- and federal-level policies impacted access to medications for opioid use disorder (MOUD) during the COVID-19 pandemic. Due to the devastating impact of overdose and COVID-19 on AI/AN communities, as a secondary aim, we examined the inclusion of these populations in the samples of the included studies.

METHODS: We completed a narrative review using a data-based convergent synthesis design.

RESULTS: Forty-four studies met the inclusion criteria. Most of the studies were quantitative descriptive studies (n = 25). Only two studies offer AI/AN as a category for ethnicity and both had less that 4% of the sample that identified as an AI/AN individual.

CONCLUSION AND IMPLICATIONS: Telehealth OUD treatment increased initiation and retention for patients taking buprenorphine. No increase in overdose rates was associated with allowing for additional take-home doses of methadone. However, access to treatment, even telehealth, remains difficult for individuals due to a lack of OUD treatment providers and access to the internet. More needs to be done to address the opioid overdose crisis, especially among AI/AN communities. Research focused on cultural strategies to address this health disparity is desperately needed. We included nursing implications in response to this health disparity among AI/AN individuals.

Emerging Respiratory Virus Threats from Influenza D and Canine Coronavirus HuPn-2018.

Emerging infectious diseases, 32(1): [Epub ahead of print].

In 2009 and again in 2019, public health warnings were confirmed by the emergence, rapid widespread transmission, and lethality of novel influenza and coronaviruses. The world continues to suffer disease from these respiratory viruses. Two newly recognized emergent respiratory viruses, influenza D and canine coronavirus HuPn-2018, have been shown to have considerable potential for causing future human epidemics, but diagnostics and surveillance for the viruses are lacking. We reviewed data regarding influenza D virus and coronavirus canine coronavirus HuPn-2018. Those data strongly indicate that these viruses are major newly recognized threats. However, little is being done to respond to or prevent disease associated with these viruses, warranting the question of whether we will learn from previous pandemics.

Strategies, interventions, and uptake of catch-up vaccination among adolescent and adult migrants, refugees, and internally displaced persons (IDPs) in low- and middle-income countries (LMICs): A systematic review.

Vaccine, 75:128249 pii:S0264-410X(26)00056-3 [Epub ahead of print].

BACKGROUND: Catch-up vaccination helps close immunity gaps among migrants, refugees and internally displaced people (IDPs) in low- and middle-income countries (LMICs). Despite immunisation life-course policies and global guidelines promoting catch-up vaccination of arriving migrants, vaccination strategies for adolescent and adult populations are poorly described. We synthesised evidence on catch-up vaccination strategies and interventions, delivery platforms, uptake and coverage, and contextual barriers and enablers in LMICs.

METHODS: We searched Embase, Medline, PsycINFO, Global Health, Web of Science and grey literature sources (including websites of international and national public health organisations and agencies) for primary studies and reports on catch-up vaccination strategies and interventions, delivery platforms, uptake and coverage, and contextual barriers and enablers targeting adolescents (9-18 years) and, or adults (≥19 years) in migrants (foreign-born, including refugees) and internally displaced people (IDPs; displaced within national borders) across 136 LMICs, (from January 1st 2000 to February 1st 2025; all languages). Study quality was accessed using ROBINS-I, CASP, AACODS and, AGREE II tools.

RESULTS: Thirty-seven records met the inclusion criteria (13 peer-reviewed, 24 grey literature), reporting catch-up vaccination activities across 16 LMICs. Most studies were conducted in Uganda (n = 6), Bangladesh (n = 4), Lebanon (n = 3), and Kenya (n = 3). Interventions reached ≥48,000 migrants, refugees, and IDPs (primarily Rohingya refugees in Bangladesh during COVID-19 catch-up campaigns). Populations targeted included mostly refugees (n = 16 studies; 43.2%), general migrants (n = 14; 37.8%), and IDPs (n = 5; 13.5%), with a smaller number involving mixed or other migrant groups (n = 4; 10.8%). The most frequently delivered vaccines were measles-rubella (n = 12; 32.4%), COVID-19 primary-series catch-up (n = 9; 24.3%), HPV (n = 6; 16.2%), polio OPV/IPV (n = 5; 13.5%), and Hepatitis B (n = 3; 8.1%). Catch-up vaccine delivery most commonly occurred through primary care via opportunistic offers (n = 11) and mobile/outreach delivery (n = 11), with additional implementation in fixed posts in camps/settlements (n = 7), supplemental immunisation activities (SIAs) (n = 6), school-linked delivery (n = 5), and hospital/outpatient opportunistic vaccination (n = 4). High uptake (≥85%) was reported where access barriers were minimised (e.g., walk-in availability, extended hours) was paired with community or peer engagement and simple recall systems (SMS or e-booking). Reported barriers included documentation/entitlement checks, language barriers, and fragmented or non-interoperable vaccination records.

CONCLUSIONS: Migrants remain at risk of under-immunisation, and greater emphasis must be placed on promotion of vaccination across the life-course for missed vaccines, doses, and boosters. Strengthening catch-up vaccination in adolescents and adults, and improving migration-disaggregated data and delivery systems, are urgently needed.

Scoping review on motorcycle crashes patterns, risk factors, and potential in setting policy priorities in the gulf cooperation council countries (GCC).

Injury, 57(3):113017 pii:S0020-1383(26)00004-5 [Epub ahead of print].

BACKGROUND: Although road traffic injuries (RTIs) pose a significant public health burden in the Gulf Cooperation Council countries (GCC), the true extent of motorcycle crash injuries (MCCIs) remains unclear because of limited published data from this region. Emerging evidence suggests that MCCIs are on the rise because of the growing use of motorcycles for transport and delivery services, even though road safety overall has improved. We sought to review regional evidence on MCCIs' patterns, key risk factors, and temporal trends to inform policy interventions and research priorities for effective prevention.

METHODS: A scoping review was conducted in accordance with the PRISMA-ScR guidelines. Articles on GCC MCCIs published from July 2008 to October 2025, examining injury patterns, mortality, and safety practices, were included in the review. Search was conducted across PubMed, Scopus, Google Scholar, and grey literature sources. The GCC consists of six countries: Saudi Arabia (KSA), Qatar, Kuwait, the United Arab Emirates (UAE), Bahrain, and Oman.

RESULTS: Of 1344 studies identified, 9 met the inclusion criteria and were analyzed. The GCC has seen an increase in the number of motorcycles registered, resulting in higher MCC rates over time. During the COVID-19 pandemic, these rates surged again as the delivery sector grew. MCCI victims were mainly young males (mean age of 29 years). Extremity injuries were the most frequent (two-thirds), followed by head injuries (20-41%), often associated with poor helmet use compliance (range 13-17%). Delivery riders represented a high-risk subgroup, reflecting occupational exposure, fatigue, and time pressure. Despite advances in trauma care, geographic gaps persist. Helmet use non-compliance, alcohol use, and inadequate documentation remain significant risk factors. Extremity injuries were the most common in the GCC.

CONCLUSION: MCCIs in the GCC are on the rise with high rates of extremity and head trauma. Poor helmet use compliance is a significant factor. Therefore, we suggest strengthening helmet use laws and safety standards, increasing community efforts, and establishing motorcycle lanes with lower speed limits. Protection for riders at work should be enhanced. Road infrastructure and robust data systems also need improvement.

From pandemic influenza to novel coronaviruses: emerging infectious diseases of the 21st century.

Diagnostic microbiology and infectious disease, 114(4):117277 pii:S0732-8893(26)00027-1 [Epub ahead of print].

Emerging infectious diseases have risen significantly in the twenty-first century as ecological disruption, climate change, expanding human-animal interfaces, and global mobility intensify opportunities for pathogen transmission. This review synthesizes historical and contemporary evidence across viral, bacterial, fungal, and parasitic threats to characterize how diverse pathogens emerge and spread. Foundational events such as the 1918 influenza pandemic, mid-century influenza pandemics, the emergence of HIV/AIDS, and the eradication of smallpox provide context for understanding modern disease dynamics. In recent decades, coronaviruses including SARS, MERS, and SARS-CoV-2, pandemic H1N1, avian influenza subtypes, and major arboviruses such as dengue, chikungunya, Zika, West Nile virus, and yellow fever have demonstrated the rapidity with which zoonotic pathogens can disseminate globally. Viral hemorrhagic fevers including Ebola, Marburg, Lassa, and Crimean-Congo hemorrhagic fever remain critical threats, especially in regions with limited health-care capacity. Concurrently, antimicrobial resistance, the emergence of Candida auris, and the climate-driven expansion of endemic mycoses involving Histoplasma, Coccidioides, and Blastomyces highlight the increasing importance of fungal pathogens. Parasitic diseases such as artemisinin-resistant malaria, zoonotic trypanosomiasis, and expanding Leishmania transmission reflect shifting ecological conditions. These patterns are shaped by intersecting drivers including deforestation, wildlife trade, agricultural intensification, urban crowding, conflict, and rapid microbial evolution that enable spillover and sustained transmission. Although advances in genomic surveillance, metagenomic diagnostics, mRNA vaccines, monoclonal antibodies, and broad-spectrum antivirals have strengthened global response capacity, substantial gaps persist in equity, surveillance, and access to countermeasures. Strengthening One Health systems and resilient public health infrastructures is essential to anticipate and mitigate emerging infectious threats.

A mixed methods systematic review on the impact of COVID-19 on healthcare workers' knowledge, attitudes and practices of infection prevention and control in the UK.

The Journal of hospital infection, 167:124-136.

Coronavirus disease 2019 (COVID-19) continues to cause healthcare-associated infections (HCAIs) in the UK. It is important to understand if infection prevention and control (IPC) guidelines are being followed to prevent future outbreaks and improve preparedness for the emergence of infectious disease. This mixed-methods systematic review aimed to explore the COVID-19 IPC knowledge, attitudes and practices (KAP) of healthcare workers (HCWs) within the UK. Database searches carried out during April 2023 and July 2024 revealed 24 eligible papers (12 quantitative, eight qualitative, four mixed methods). A convergent integrated approach was used during qualitative synthesis. Doctors were most represented, followed by nurses then pharmacists. Personal protective equipment (PPE) was the most reported IPC measure. In terms of knowledge, articles reported moderate-to-poor knowledge of correct aerosol-generating procedures (range 33-35%), and donning and doffing procedures (range 3-82%). Intensive care workers and doctors tended to have better knowledge compared with other settings or HCWs. Regarding attitudes, PPE and gatekeeping visitation caused strain, and some HCWs felt that guidance lacked relevance to their setting. Finally, regarding practices, this review found that HCWs would risk assess what PPE to wear. An enhanced level of PPE than advised was worn when patients were symptomatic. However, HCWs would remove PPE when they felt it reduced effective communication or patient safety was at risk. Clearer communication of the evidence behind IPC guidance and tailored guidance for each setting may improve HCWs' KAP and thus reduce HCAIs. Future research should determine KAP of other IPC apart from PPE. Non-medical HCWs should also be included as they constitute a significant proportion of patient-facing staff.

Prevention, diagnosis and management of community acquired respiratory virus infections including COVID-19 in patients with cancer: 2025 updated evidence-based guideline of the infectious diseases working party (AGIHO) of the German society for hematology and medical oncology (DGHO).

Annals of hematology, 105(2):46.

Community-acquired respiratory viruses (CARV), such as influenza-, parainfluenza- or respiratory syncytial virus, pose a significant threat to immunocompromised patients with cancer. Following the COVID-19 pandemic, SARS-CoV-2 has now joined the ranks of endemic respiratory viruses and continues to be a cause of significant morbidity and mortality in patients with cancer. Strategies to protect this vulnerable patient population both by prevention of infection and by early therapeutic intervention in case of infectious disease are therefore of utmost importance. This guideline provides updated evidence-based recommendations on diagnosis, prophylaxis and treatment of CARV infections including COVID-19 in patients with solid tumors or hematologic malignancies to support clinicians in offering optimal care. The guideline is based on a systematic review of currently available data and was developed until the beginning of 2025 by an expert panel of the Infectious Diseases Working Party (AGIHO) of the German Society for Hematology and Medical Oncology (DGHO).

Neutrophil-Galectin-9 Axis Linking Innate and Adaptive Immunity in ATL, Sézary Syndrome, COVID-19, and Psoriasis: An AI-Assisted Integrative Review.

Reports (MDPI), 9(1):.

Beyond their traditional role as short-lived antimicrobial cells, neutrophils are increasingly recognized as key regulators of adaptive immunity and tumor progression. This AI-assisted integrative review investigated the neutrophil-T-cell axis, particularly the role of Galectin-9 (Gal-9), across adult T-cell leukemia/lymphoma (ATL), Sézary syndrome (SS), coronavirus disease 2019 (COVID-19), and psoriasis. Leveraging AI tools (GPT-5 and Adobe Acrobat AI Assistant) for literature synthesis (2000-2025) and expert validation, we aimed to identify common immunological mechanisms. Across all conditions, neutrophils displayed persistent activation, elevated Gal-9 expression, and modulated T-cell interactions. In ATL and SS, neutrophilia correlated with poor survival and TCR signaling dysregulation, suggesting Gal-9-mediated immune modulation. In COVID-19 and psoriasis, neutrophil-derived Gal-9-linked innate hyperactivation to T-cell exhaustion and IL-17-driven inflammation. These findings define a recurring neutrophil-Gal-9 regulatory module connecting innate and adaptive immune responses. This study underscores the feasibility of combining AI-driven literature synthesis with expert review to identify unifying immunological mechanisms and therapeutic targets across malignancy and inflammation.

Severity Scores in SARS-CoV-2 Infection-A Comprehensive Bibliometric Review and Visualization Analysis.

Epidemiologia (Basel, Switzerland), 7(1):.

BACKGROUND/OBJECTIVES: Discovered in 2019, COVID-19 spread rapidly worldwide, leading from mild forms of the disease to critical forms or death, predominantly among vulnerable patients. Severity scores help clinicians in stratifying the risk of complications and death among patients diagnosed with SARS-CoV-2 infection.

METHODS: This study aims to identify the severity scores used in this type of infection, while bibliometric analysis carried out provided a comprehensive overview of global research patterns, trends, and cooperation in scientific literature on the chosen topic.

RESULTS: We conducted a literature screening to identify severity scores used in SARS-CoV-2 infection. Scores including CURB-54, COVID-GRAM, NEWS, APACHE II, SOFA, qSOFA, CALL, MuLBSTA, ISARIC 4C, and PADUA were identified with different performance indices.

CONCLUSIONS: There were different results obtained depending on the geographical area of applicability, patient groups analyzed, and individual patient characteristics.

Infections After International Travel: Relevant Diagnoses in Children and Adolescents.

Deutsches Arzteblatt international pii:arztebl.m2025.0201 [Epub ahead of print].

BACKGROUND: Families can acquire infections that are rare or nonexistent in Germany by international travel for business or private reasons and by migration between countries. Children and adolescents have special risk profiles, and their course of illness may be nonspecific and/or severe. A structured travel history is essential so that regionally specific infections will not be overlooked.

METHODS: This narrative review is based on publications of the last 25 years that were retrieved by a PubMed search on infections after international travel, with an emphasis on retrospective and prospective studies and on articles with separate data on minors. Further information from books, guidelines, surveillance studies, reports of the Federal Statistical Office of Germany, meta-analyses, reviews, and position statements was considered as well.

RESULTS: Reported case numbers of infectious diseases imported from abroad fell during the COVID-19 pandemic and have since risen again. Among diseases that are usually or exclusively acquired abroad, those most commonly affecting children and adolescents were giardiasis, tuberculosis, hepatitis A and malaria, with 695, 372, 344, and 128 cases in 2024. Less common ones included dengue fever (81 cases) and typhoid fever/paratyphoid fever (45 cases).

CONCLUSION: Regionally specific infections should be considered in the differential diagnosis of fever, gastrointestinal disturbances, and skin conditions in children and adolescents after international travel. It is critical that relevant diseases including malaria and typhoid fever/paratyphoid fever must be promptly diagnosed or ruled out. Because resistance patterns differ across regions of the globe, targeted determination of the pathogenic organism including a resistogram is important. The possibility of chronic infection should be considered in particular after long stays abroad.

Mobile apps, AI, and teletherapy: a comprehensive review of digital mental health tools for nurses.

Frontiers in public health, 13:1686766.

Chronic understaffing, workplace violence, moral distress, rotating shifts, and administrative burdens have created a global mental health crisis for nurses. Around half to two-thirds of nurses report symptoms of burnout, and large surveys have found high levels of depression and anxiety among nursing staff. The COVID-19 pandemic exacerbated these issues, increasing absenteeism, turnover, and error rates. Barriers to care-such as stigma, cost, and limited access in rural areas-mean that many nurses remain untreated. Digital mental health interventions (DMHIs) offer scalable, flexible, and often anonymous support tailored to nurses' schedules and risks. These include teletherapy platforms, AI-driven chatbots and support systems, mobile mental health apps, and hybrid digital-human models. Recent studies (2020-2025) suggest DMHIs can reduce anxiety, depression, and burnout while improving resilience, job satisfaction, and retention. However, obstacles such as unequal access, variable digital literacy, privacy concerns, and limited long-term evidence slow adoption. This review synthesizes current research on DMHI types and efficacy, and examines factors affecting their accessibility and integration into nursing practice. We also discuss cultural and ethical considerations and strategies for involving nurses in designing these tools. Our analysis identifies gaps and opportunities for developing nurse-centered digital mental health solutions that strengthen the workforce and improve patient care.

Neurological Complications Associated With COVID-19 Compared to Other Viral Infections: A Systematic Review of Current Evidence.

Cureus, 18(1):e101817.

Neurological complications have become one of the most concerning features of COVID-19, yet clinicians still lack a clear comparison between these findings and what is seen in other viral infections. Understanding where SARS-CoV-2 fits, whether it behaves like influenza and dengue or follows an entirely different pattern, is essential for diagnosis, management, and planning long-term care. We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO: CRD420251064831). Searches across PubMed, Scopus, and Web of Science (2000-2025) identified 24 eligible studies, including observational cohorts, clinical trials, case series, autopsy work, and national surveillance data. Because of the wide variation in study design and reporting, a narrative synthesis was used. Across the 24 studies, COVID-19 exhibited the widest and most severe spectrum of neurological involvement. Reported central nervous system complications included ischemic stroke, encephalopathy or encephalitis, seizures, and extensive microglial and white-matter injury in fatal cases. Peripheral complications were also prominent, such as anosmia, demyelinating neuropathies, Guillain-Barré syndrome (GBS), chronic inflammatory demyelinating polyneuropathy, functional movement disorders, and persistent abnormalities on nerve conduction testing long after recovery. In contrast, neurological complications from influenza were less frequent and mostly involved encephalitis/encephalopathy, seizures, meningitis, GBS, or myelitis, with generally low mortality. Dengue virus has been associated with a spectrum of direct neurotropic effects and immune-mediated syndromes, including encephalitis, GBS, myelitis, brachial neuritis, and myositis. Most patients recovered, and mortality remained low. Compared with influenza and dengue, COVID-19 stands out for both the breadth and severity of its neurological manifestations, as well as the persistence of symptoms in many survivors. These findings highlight the need for early neurological evaluation in COVID-19, structured follow-up after recovery, and more consistent research methods to allow better comparisons across viral infections.

Cardiovascular abnormalities in multisystem inflammatory syndrome in children related to COVID-19.

Frontiers in pediatrics, 13:1635723.

INTRODUCTION: The COVID-19 pandemic began with the identification of SARS-CoV-2 in December 2019. Although children usually have milder acute symptoms, they can develop severe systemic symptoms termed pediatric multisystem inflammatory syndrome (MIS-C). This study reviews research in children and adolescents diagnosed with MIS-C, focusing on cardiovascular abnormalities.

METHODOLOGY: This systematic review was conducted following PRISMA guidelines. The review protocol was prospectively registered in the Prospective Register of Systematic Reviews (PROSPERO; registration number: CDR420251232497). A search strategy was constructed to identify the studies focusing on cardiovascular abnormalities in children and adolescents with MIS-C published in Portuguese and English at PubMed and Scielo from January 2020 to February 2025. The eligibility criteria and data extraction strategy were guided by the PICO framework.

CONCLUSIONS: Myocardial dysfunction and coronary abnormalities are the most frequent cardiovascular features in patients with MIS-C. Strain technology in echocardiography identifies early myocardial dysfunction, with studies showing persistent subclinical injuries. Despite ejection fraction and coronary anomalies returning to normal short to medium term, long-term cardiovascular effects of MIS-C remain uncertain, necessitating ongoing cardiology monitoring.

Triplet regimens for frontline treatment of CLL-Great company or just a crowd?.

HemaSphere, 10(1):e70303.

Standard frontline treatment of chronic lymphocytic leukemia (CLL) is with fixed-duration venetoclax-based doublets or indefinite covalent Bruton tyrosine kinase inhibitor (BTKI). Although these approaches achieve excellent results, venetoclax doublets have diminished efficacy in high-risk biological subgroups, and indefinite covalent Bruton tyrosine kinase inhibitor (cBTKI) is associated with cumulative cardiovascular and infectious toxicity. Triplet regimens for treatment of CLL involve simultaneous use of cBTKI, venetoclax, and anti-CD20 monoclonal antibody. Three major frontline Phase 3 trials (CLL-13/GAIA, AMPLIFY, and A041702) have demonstrated higher rates of undetectable minimal residual disease (uMRD) and longer remissions with triplets than doublets, particularly in patients with IGHV-unmutated (IGHV-U) disease. However, this comes at the cost of increased infectious toxicity, particularly with COVID-19, and thus has translated into a variable impact on progression-free survival (PFS) and, to-date, no overall survival (OS) benefit. Although there are promising Phase 2 data for triplets in patients with TP53 aberrant or relapsed disease, the heterogeneity of treatment duration/MRD definition, lack of control arm, and potential increased toxicity make it premature to use triplets in these groups. We recommend considering triplets in treatment naïve CLL patients with IGHV-U, TP53 wild type, anticipated low incidence/good tolerance of Gr ≥ 3 infection (<70 years old, no major comorbidity and fully immunized) who are well informed and prioritize maximal time off therapy at the expense of increased short-term logistical complexity. Future triplet research should focus on randomized trials in specific genomic subgroups, incorporating novel agents (e.g., non-covalent BTKI, BTK degrader, and next-generation BCL2 inhibitors) and new ways of adapting treatment duration to maximize efficacy and minimize toxicity.

Decoding miRNA-Mediated Immunoregulation in SARS-CoV-2, HBV, HIV, and HSV Infections.

Genes and immunity [Epub ahead of print].

Eukaryotic cells regulate gene expression through multiple checkpoints, including post-transcriptional mechanisms mediated by microRNAs (miRNAs). These small non-coding RNAs inhibit translation by binding to target mRNAs, often within a complex regulatory network involving other RNA species such as circular RNAs and long non-coding RNAs. miRNAs are now recognised as central players in the pathogenesis, immune modulation, and progression of infectious diseases. In this review, we thoroughly examine studies published over the past five years, focusing on miRNAs involved in immune regulation during four major viral infections: severe acute respiratory syndrome coronavirus 2, hepatitis B virus, human immunodeficiency virus, and herpes simplex virus. Our analysis centres on the core signalling pathways most frequently targeted by miRNAs: NF-κB, MAPK, JAK-STAT, TGF-β/Smad, and pattern-recognition receptor-associated cascades. Among the miRNAs most prominently implicated are miR-21, miR-146a, miR-150, and miR-155. These miRNAs modulate key signalling pathways, thereby influencing macrophage polarisation, T- and natural killer cell activity, antigen presentation, and inflammatory cytokine production. In addition, virus-encoded miRNAs and ceRNA or extracellular vesicle-mediated interactions are discussed where mechanistically validated, illustrating virus-specific regulatory layers. Collectively, this integrative synthesis underscores the pivotal roles of miRNAs in orchestrating antiviral immunity and highlights their potential as biomarkers and therapeutic targets in viral infections. A better understanding of miRNA-mediated immunoregulation may pave the way for precision interventions aimed at improving immune control and patient outcomes.

Evaluating Cardiovascular Disease Risk.

Journal of insurance medicine (New York, N.Y.) [Epub ahead of print].

There was a steady decrease in cardiovascular disease (CVD ischemic heart disease and stroke) mortality from 1960 to 2020, but since then, this decline has reversed. There have been over 228,000 excess CVD deaths through 2022,1 undoubtedly partially due to the COVID-19 pandemic, but the mortality rate continues to rise (arguably due to the rising epidemic of obesity and diabetes). CVD remains the leading cause of death in developed countries, accounting for over 30% of deaths, and risk estimation is a cornerstone approach to guiding CVD prevention in clinical medicine. Data from the CDC reveal that 36% of US adults have no CVD risk factors, 35% have 1, and 29% have 2 or more risk factors. The age-adjusted percentage of adults with 2 or more CVD risk factors has increased between 2013-2014 to August 2021-August 2023, especially in older age groups.2 Assessing the risk for CVD mortality is essential for the disability and life insurance industry required to assess that risk at a single point in time (at the issuance of an insurance policy). Evaluating this risk requires careful attention to modifiable and non-modifiable factors, including hypertension and other co-morbidities, abnormal lipid profiles, and lifestyle inequalities. The goal of this treatise is to evaluate the various CVD calculators, but also to review other risk factors that may not be routinely sought in estimating CVD risk. The importance of apolipoproteinB (apoB) and lipoprotein A (LpA) as better risk predictors than just elevated LDL levels will be emphasized, and evidence of systemic inflammation and insulin resistance will be proposed as essential early indicators of future cardiovascular disease.

Absorption, distribution, metabolism, and excretion tactics toward the expedited discovery and development of the severe acute respiratory syndrome coronavirus-2 main protease inhibitor nirmatrelvir.

Drug metabolism and disposition: the biological fate of chemicals, 54(2):100226 pii:S0090-9556(25)09535-2 [Epub ahead of print].

The severe acute respiratory syndrome coronavirus-2 main protease inhibitor PF-07321332 (nirmatrelvir), in combination with ritonavir (Paxlovid), has been approved by the US Food and Drug Administration as an oral treatment option for coronavirus disease 2019 patients. In this perspective, we share the expediated absorption, distribution, metabolism, and excretion strategies, which were incorporated as part of discovery efforts, to design orally active severe acute respiratory syndrome coronavirus-2 main protease inhibitors. PF-07321332 (nirmatrelvir) emerged as a potential oral clinical candidate within ∼ 6 months from the time discovery efforts were first initiated. The review also delves into a discussion around the successful use of quantitative fluorine-19 nuclear magnetic resonance spectroscopy in the characterization of the human mass balance and excretion pathways of nirmatrelvir. Human absorption, distribution, metabolism, and excretion data that emerged from the fluorine-19 nuclear magnetic resonance study were used to support the Emergency Use Authorization and new drug application filing, which was accepted by regulatory agencies worldwide. Efficient operational and technical strategies, incorporating the elements of speed without sacrificing data quality, which were crucial to the success of the program, are highlighted. SIGNIFICANCE STATEMENT: This perspective discusses the expedited absorption, distribution, metabolism, and excretion efforts utilized in the discovery and development of the orally active severe acute respiratory syndrome coronavirus-2 main protease inhibitor nirmatrelvir, which in combination with the cytochrome P450 3A inhibitor ritonavir (Paxlovid), is used in the oral treatment of COVID-19. Paxlovid was granted an Emergency Use Authorization by global regulatory agencies in less than 2 years from the initiation of the discovery program and has since been fully approved by the US Food and Drug Administration.

Effects of atorvastatin on inflammatory markers, lipid profile, liver enzymes, and pulmonary function in patients with lung diseases: a systematic review and meta-analysis of randomized controlled trials.

European journal of medical research, 31(1):111.

BACKGROUND: Pulmonary diseases are important causes of morbidity globally. Atorvastatin's pleiotropic effects, which include anti-inflammatory and lipid-lowering properties, may be beneficial for individuals with respiratory diseases. This meta-analysis evaluated the atorvastatin's effect on inflammatory biomarkers, lipid profile, liver enzymes, and pulmonary function in lung disease patients.

METHODS: We systematically searched PubMed/MEDLINE, Scopus, Web of Science, Embase, CENTRAL, and Google Scholar for English-language RCTs until March 2025. The study evaluated inflammatory markers (CRP, IL-6, TNF-α), lipid profile (LDL, HDL, TC, TG), liver enzymes (ALT, AST), pulmonary function tests, and physical performance. Pooled weighted mean differences (WMDs) with 95% confidence intervals were calculated using random-effects models. Subgroup, heterogeneity, and publication bias analyses were conducted.

RESULTS: Seventeen RCTs (22 datasets; n = 1,344) on asthma, COPD, COVID-19, pulmonary hypertension, and associated disorders were analyzed. Atorvastatin substantially decreased TNF-α (WMD: - 0.20 pg/mL; 95% CI - 0.28 to - 0.11), LDL cholesterol (WMD: - 21.48 mg/dL; 95% CI - 30.82 to - 12.14), and TC (WMD: - 15.24 mg/dL; 95% CI - 28.28 to - 2.20), while improving 6MWD (WMD: 0.71; 95% CI 0.24 to 1.17) and FEF25-75 in COPD subgroups. Evening peak expiratory flow (PEF) was considerably lower (WMD: - 8.72; 95% CI - 14.96 to - 2.47), indicating worsening in airway airflow throughout the evening. There were no significant overall effects for CRP, IL-6, triglycerides, HDL, FEV1, FVC, or oxygen saturation.

CONCLUSIONS: Atorvastatin demonstrates anti-inflammatory and lipid-lowering efficacy in pulmonary disease patients, with mild functional respiratory benefits and modest improvements in physical performance. Additional large-scale studies are needed to validate clinical benefits and effective treatment methods.

Comparison of Teledentistry and Traditional Clinical Examination for Detection of DMFT Index in Children: A Systematic Review.

Pediatric dentistry, 47(6):380-387.

Purpose: This study systematically analyzed the published literature to evaluate the reliability of the caries experience index detection conducted in children (younger than 18 years of age) through teledental systems, comparing it with data obtained through traditional dental consultations. The question to be explored was whether dentists could use teledentistry to assess the caries risk index by calculating the DMFT (decayed, missing, and filled permanent teeth) score, thereby potentially reducing consultation time. Methods: A systematic English-language literature review was conducted, including the period from 2014 to 2024, that included the MeSH terms (("telemedicine"[Mesh]) AND "dental caries"[Mesh]) AND "DMF index"[Mesh]). Inclusion and exclusion criteria were defined according to the PICO methodology. A total of 11 manuscripts met the inclusion criteria. The methodological quality of these studies was assessed using the Newcastle-Ottawa Scale (NOS) with specific tools for cross-over studies. Results: From the 11 studies reviewed, it was suggested that teledentistry, through the use of intraoral photographs or video recordings, may represent a reliable, noninvasive, and efficient alternative for the detection of the caries experience index, compared to clinical examinations performed according to the traditional method. In most cases, the results were comparable between the two approaches. Conclusion: Incorporating teledentistry in combination with regular dental appointments could streamline clinical processes, enable effective treatment planning, and facilitate remote monitoring of the oral health status of patients, making it a timely and contemporary solution for a connected and health-conscious society-which is particularly valuable during public health crises such as the COVID-19 pandemic.

Emergency Department Crowding in the Modern Era: A Systematic Review (2018-2025).

Clinical and experimental emergency medicine pii:ceem.25.172 [Epub ahead of print].

OBJECTIVE: This study systematically reviews the causes, effects, and potential solutions to emergency department (ED) crowding, with emphasis on challenges amplified by the COVID-19 pandemic.

METHODS: Following PRISMA guidelines, we searched MEDLINE, CINAHL, and Web of Science for peer-reviewed studies published from January 1, 2018, to January 31, 2025, that investigated ED crowding. Studies were included if they evaluated crowding causes, consequences, or interventions, using metrics such as ED length of stay, boarding, or left without being seen. Four reviewers independently screened titles, abstracts, and full texts. Study quality was assessed using the Scottish Intercollegiate Guidelines Network (SIGN) critical appraisal tools. This review was registered with PROSPERO (CRD420251117676).

RESULTS: Of 23,408 studies identified, 226 met inclusion criteria. Most studies were retrospective (83%) and of low (62%) or acceptable (35%) quality. Crowding was primarily driven by input (high patient volumes, limited primary care access), throughput (staffing shortages, laboratory and imaging delays), and output (boarding, late discharges) factors. Adverse effects included increased mortality, treatment delays, prolonged inpatient stays, higher rates of patients leaving without being seen, and reduced patient satisfaction. Effective strategies included provider-in-triage, nurse-initiated orders, and split-flow models. Output-focused interventions, such as active bed management and early discharge protocols, required system wide coordination. The COVID-19 pandemic shifted patient volumes and led to innovative solutions such as drive-through clinics and repurposed spaces to alleviate surges.

CONCLUSION: ED crowding is a persistent global issue with significant clinical and operational consequences. While promising interventions exist, high-quality evidence remains limited, underscoring the need for system-level and multifaceted solutions.

[Work-related fatigue in anesthesia and intensive care medicine : Review article on a structural problem].

Die Anaesthesiologie [Epub ahead of print].

Work-related fatigue is a serious psychophysiological phenomenon characterized by exhaustion, impaired concentration, reduced alertness and diminished decision-making capacity. It often results from disrupted sleep patterns and shift work and increases the risk of critical incidents in the clinical practice. Anesthetists are particularly affected as irregular working hours and frequent night shifts disrupt their circadian rhythms. Although fatigue is reversible with appropriate measures, it remains largely unrecognized as a structural issue within the German healthcare system.Over recent decades the working conditions across European healthcare settings have steadily deteriorated, a trend that culminated during the COVID-19 pandemic. This period clearly highlighted the urgent need to prioritize the well-being of healthcare professionals. The aim of this review article is to raise awareness of fatigue and provide insights into effective management strategies. It explores both international concepts and local solutions relevant to the German system.This review and analysis are based on studies and material developed as part of the European "Fatigue Project" and the "Fight Fatigue" campaign. It examines the effects of fatigue across all career stages and identifies practical strategies for risk reduction.The results show that fatigue affects anesthetists at all stages of their careers. Structured fatigue management is therefore a vital component of sustainable healthcare provision. In particular, fatigue risk management systems and optimized shift work planning have proven effective in reducing the burden on personnel and enhancing patient safety.

Genetic insights into hepatitis E virus through environmental surveillance in Europe.

One health (Amsterdam, Netherlands), 22:101302.

Zoonotic hepatitis E has been a growing public health concern in Europe, but the transmission of its causative agent, hepatitis E virus (HEV), remains incompletely understood. Environmental surveillance, particularly through wastewater monitoring, has proven valuable for tracking viral circulation and variant shift during the COVID-19 pandemic, yet its application to HEV is still limited. In this review, we systematically analyzed HEV sequences across Europe, focusing on environmental sources from a genetic perspective. Of more than 13,100 HEV sequences deposited in the NCBI database, only 2.4 % (316/13,118) originated from environmental samples, including wastewater, surface water, and biosolids. Additional typing data from the literature revealed highly uneven geographic distribution, with 97 % of environmental sequences reported from Italy, France, the United Kingdom (UK), Spain, Sweden, and Germany. HEV-3 was the dominant genotype, while HEV-1 and HEV-4 were occasionally detected. Subtypes 3c and 3f were most common, but their prevalence varied across countries and sample types. Some countries, such as France, Sweden, and the UK, exhibited divergent subtype patterns between humans, animals, and environmental sources, whereas others, such as Spain and Germany, showed more consistent distributions. These findings highlight the importance of integrating clinical, veterinary, and environmental surveillance to better understand HEV transmission in Europe under a One Health framework. However, the scarcity of environmental data, technical challenges in sequencing, and lack of standardized protocols limit comprehensive assessment of HEV circulation. Expanding sequencing efforts, improving detection methods, and coordinating international surveillance frameworks will be critical to strengthen HEV monitoring and preparedness against emerging HEV threats.

Progress in the Application of Pirfenidone in Post-COVID-19 Pulmonary Fibrosis: A Review.

Cureus, 17(12):e99490.

Pulmonary fibrosis following infection with the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has emerged as a significant long-term complication among survivors of coronavirus disease 2019 (COVID-19), profoundly affecting their quality of life and clinical outcomes. This review provides a comprehensive overview of the pathophysiological mechanisms underlying post-COVID-19 pulmonary fibrosis and elucidates the pharmacological actions of pirfenidone, a multi-targeted antifibrotic agent in this context. We summarize the current clinical evidence on the efficacy and safety of pirfenidone for managing fibrosis secondary to SARS-CoV-2 infection, drawing on recent advances in basic and clinical research. Furthermore, we discuss existing challenges, unresolved questions, and prospective directions for optimizing antifibrotic therapy in COVID-19 convalescents. By systematically analyzing these aspects, this article aims to offer theoretical support and practical guidance to clinicians and researchers addressing the management of post-COVID-19 pulmonary fibrosis.

Anxiety and depressive symptoms among medical students-A scoping review of systematic reviews and meta-analyses.

Frontiers in public health, 13:1710333.

BACKGROUND: Medical schools are globally recognized as higher education institutions requiring extreme dedication from students. The intensive nature of physician training demands heavy workloads, inconsistent sleep, and study-leisure imbalances. Such stressors are linked to poor student mental health, with anxiety and depression symptoms among the most documented disorders. These burdens negatively affect academic performance and are associated with dropout intentions, misconduct, burnout, and suicidal ideation.

OBJECTIVE: This scoping review summarizes recent evidence on the prevalence of anxiety and depression symptoms among medical students and identifies correlated factors.

METHODS: The review followed PRISMA guidelines and Arksey and O'Malley's five-stage methodological framework. Searches were conducted on July 5, 2025, in PubMed, MEDLINE, Web of Science, Scopus, and PsycINFO. Boolean operators combined terms related to prevalence, and correlates of depressive and anxiety symptoms, and medical students, limited to systematic reviews and meta-analyses published in English between January 2021 and July 2025. Sixteen studies met the inclusion criteria after screening. Data were charted for study characteristics, prevalence estimates, contributing factors, and methodological approaches.

RESULTS: The studies included in this review reported wide-ranging prevalence estimates, with the prevalence of depression symptoms in the included meta-analysis ranging from lowest of 18.1% to highest of 50.0% and anxiety symptoms from 17 to 54% although there was high heterogeneity in the screening instruments or measurement scales Biological sex differences in prevalence were frequently noted, with most studies reporting a higher prevalence among females; however, findings varied by region. Regional disparities were additionally observed, with some continents and countries reporting significantly higher prevalence rates than others. Factors associated with increased risk included early years of study, poor sleep quality, and academic stress. During COVID-19, most studies reported a higher prevalence of depression and anxiety symptoms than pre-pandemic levels.

CONCLUSIONS: Anxiety and depressive symptoms remain widespread among medical students, driven by individual and contextual factors. Targeted interventions and early preventive strategies are urgently needed to address mental health challenges and protect student wellbeing.

IL-7: a potential next-generation adjuvant for immune cell therapies.

Frontiers in immunology, 16:1736931.

Cell-based immune therapies ranging from CAR-T cells to tumor infiltrating lymphocytes (TILs) and endogenous T-cell products, have produced unprecedented clinical responses in hematologic malignancies and are currently under active investigation for solid tumors. Nevertheless, several key challenges continue to limit the durability and breadth of clinical benefit. IL-7 is a pleiotropic cytokine that increases both the number and function of lymphocytes. Although not yet clinically approved, IL-7 has been used in over 620 adult and pediatric patients for a variety of reasons including, for example, to hasten bone marrow recovery after allogenic stem cell transplantation, to reverse lymphopenia due to HIV and idiopathic etiologies, to treat patients with various malignancies, and to boost vaccine responses. IL-7 is generally well-tolerated and effective in producing a durable increase in the number and function of CD4 and CD8 T cells. Recently, IL-7 has been used clinically in multiple myeloma patients receiving CAR-T cell therapy, in patients with urothelial cancer who are receiving checkpoint inhibitors, in patients undergoing endogenous lymphocyte cell therapy, and in critically-ill lymphopenic patients with COVID-19. The authors, all of whom have used IL-7 clinically, discuss how IL-7 effectively addresses all the major problems currently limiting adoptive cell therapies. Peering into the future, we believe that IL-7 will be a major advance as an adjuvant treatment in many cell therapies and hope that this commentary will expedite IL-7's testing in multiple clinical settings.

Bronchiolitis and recurrent respiratory infections: The role of oxidative stress from early life inflammation to long-term outcomes - A narrative review.

The World Allergy Organization journal, 19(1):101162.

Bronchiolitis, primarily caused by respiratory syncytial virus (RSV), is a common respiratory infection in infants and a known precursor to recurrent wheezing and asthma. This review explores the role of oxidative stress and trace element deficiencies in the pathogenesis of bronchiolitis and its long-term sequelae. Infants with reduced lung function due to prematurity or congenital airway anomalies exhibit heightened susceptibility to RSV infection. Growing evidence implicates oxidative stress and deficiencies in zinc, selenium, and magnesium as significant contributors to disease progression. Impaired antioxidant defenses exacerbate viral inflammatory responses, leading to prolonged symptoms and recurrent wheezing with potential developmental delays. Studies consistently demonstrate that children with bronchiolitis exhibit elevated oxidative stress markers and reduced antioxidant capacity, with trace element deficiencies correlating with disease severity. Reduced defenses against oxidative stress may be associated with recurrent wheezing episodes, which are more frequent after rhinovirus bronchiolitis than after RSV bronchiolitis. Thus, RSV and rhinovirus (RV) bronchiolitis may unmask pre-existing vulnerabilities rather than directly causing long-term damage associated with later asthma. Micronutrient supplementation, particularly zinc and selenium, has shown potential in reducing respiratory infection duration and severity. COVID-19 pandemic evidence further supports nutritional status as a key modulator of respiratory disease outcomes, with nutraceuticals like curcumin and flavonoids demonstrating anti-inflammatory benefits. Given the safety and accessibility of micronutrient supplementation, early nutritional assessment and intervention in high-risk infants may offer a cost-effective strategy to improve long-term respiratory outcomes. Bronchiolitis should be viewed as a clinical signal warranting proactive, holistic pediatric care rather than merely an acute illness.

Conquering viral drug resistance: Structural and mechanistic paradigms for antiresistance drug design.

Pharmaceutical science advances, 3:100094.

Viral drug resistance remains a critical challenge in antiviral therapy. This perspective highlights five studies on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), human immunodeficiency virus type 1 (HIV-1), monkeypox virus (MPXV), influenza A virus (IAV), and Hepatitis B virus (HBV), revealing novel resistance mechanisms and innovative strategies. For SARS-CoV-2, GC376's flexible benzyl group overcomes nirmatrelvir resistance. HIV-1's non-nucleoside reverse transcriptase inhibitors (NNRTIs) 5i3 adapts to resistant mutants via a quinazoline scaffold, while MPXV's tecovirimat acts as a "molecular glue" stabilizing F13 dimers. Expanding these paradigms, we present groundbreaking insights: An indazole-based IAV inhibitor (compound 24) disrupts the conserved PA-PB1 heterodimer, showing sub-micromolar potency against resistant strains. For HBV, a hydrophobic tagging degrader (HyT-S7) induces HBc degradation, bypassing resistance mutations impairing traditional capsid modulators. Key strategies include dynamic flexibility, multivalent interactions, and oligomerization control, integrated with AI-driven design and real-time surveillance. This perspective bridges structural insights with translational applications, offering a roadmap for next-generation, mutation-resilient antivirals.

Strategies for mitigating severe COVID-19 in patients with haematological malignancy during the omicron era.

The Journal of antimicrobial chemotherapy, 81(2):.

Despite a decrease in disease severity since the emergence of the severe acute respiratory syndrome coronavirus 2 Omicron variant, coronavirus disease-2019 (COVID-19) continues to pose a significant threat to patients with haematological malignancies (HM). Although repeated booster vaccinations enhance protection against severe illnesses in immunocompromised individuals, they remain at heightened risk of adverse outcomes. This underscores the crucial need for effective pharmacologic strategies to prevent and treat infection. This review examines current strategies for preventing severe COVID-19 in patients with HM, focusing on pre-exposure prophylaxis and early treatment of COVID-19. New monoclonal antibodies have been developed, offering effective pre-exposure prophylaxis. Antiviral agents and monoclonal antibodies demonstrated efficacy in limiting severe COVID-19 outcomes in patients with HM, though some patients, particularly the elderly, remain at risk of critical illness and death. Prolonged infection over months is also common, particularly in patients with lymphoid malignancies. Sustained viral shedding and ongoing mutation may be associated with chronic symptoms and is the likely source of several novel variants of concern that prolonged the pandemic. While HM subtype and advanced age are risk factors for severe or persistent COVID-19, there are no accurate tools for predicting individual risk. Given this uncertainty, prompt medical consultation, timely prescription of antiviral agents, and close monitoring are essential to minimize the risk of adverse outcomes in this vulnerable population.

Science translation strategies to the public during health emergencies: A systematic review of RCTs.

Patient education and counseling, 145:109479 pii:S0738-3991(26)00012-1 [Epub ahead of print].

INTRODUCTION: Effective science translation is essential during public health emergencies. During the COVID-19 pandemic, rapidly evolving research had to be translated to the public under challenging conditions.

OBJECTIVES: This review aimed to identify randomised trials of COVID-19 science translation strategies targeting the public and evaluated their effectiveness in improving psychological, behavioural and/or health outcomes.

METHODS: A literature search was done across PubMed, Embase, Scopus, CINAHL, and PsycINFO in July 2023 and November 2024. Studies were screened and extracted according to PRISMA guidelines. Interventions reporting behavioural outcomes were coded using the Behaviour Change Technique (BCT) taxonomy and the Cochrane risk-of-bias tool was used to assess study quality.

RESULTS: Of 345 records screened, 48 eligible studies were included. Most were online experiments testing message framing, with a smaller number conducted in applied settings such as health professional-delivered education. Significant positive effects were reported in most studies; 30 out of 40 studies with psychological outcomes (e.g. knowledge), 28 out of 40 studies with behavioural outcomes (e.g. intention to mask). Only one study measured a health outcome, with no significant effect. Effective features commonly included video and animation formats and messages from health experts and credible sources. The most frequent BCTs were 'information about health consequences' (33 studies) and 'credible source' (19 studies). Risk of bias was low in 42 studies.

CONCLUSIONS: These findings highlight a diverse range of strategies that improved outcomes during the COVID-19 pandemic. Better use of behavioural science taxonomies and core outcome sets could help researchers advance the field further during future emergencies.

PRACTICE IMPLICATIONS: This review provides insights for a range of stakeholders involved in science translation during emergencies (i.e. scientists and researchers, healthcare providers, health communicators and government officials) and highlights areas requiring further investigation.

Is anybody out there? Tackling intimate partner violence as a hidden pandemic during COVID times and beyond: factors, impact, and recommendations, a systematic review and meta-analyses.

Archives of women's mental health, 29(1):20.

PURPOSE: Intimate partner violence is a pervasive issue deeply affecting public health, and its escalation during the COVID-19 pandemic has raised serious concerns. While the escalating impact of intimate partner violence during the COVID-19 pandemic has been widely acknowledged, there remains a need for a comprehensive systematic review that synthesizes existing literature. This review seeks to address this gap by providing an inclusive assessment of the global landscape of intimate partner violence during and after the pandemic, thereby informing more effective prevention and intervention strategies.

METHODS: A systematic literature search was conducted on PubMed, Google Scholar, and Scopus databases using different MeSH terms. A total of 445 relevant articles were identified initially, and after thorough screening, 54 articles were included in the review.

RESULTS: The lockdown had several negative consequences, including job losses, economic vulnerability, and health issues due to prolonged loneliness and uncertainty. An increase in emergency hotline or Women's Helpline calls was observed. Globally, intimate partner violence surged during the lockdown and persisted into 2023, causing severe and lasting health, psychological, and reproductive consequences for victims. Our results showed that COVID-19 increased the risk of partner violence: post-COVID intimate partner violence risk greater than pre-COVID risk (0.33 vs. 0.28, respectively).

CONCLUSION: Although COVID-19 increased the risk of intimate partner violence, this review also stresses a high global prevalence of intimate partner violence, not restricted to the pandemic and lockdowns. To prevent partner violence and reduce long-lasting severe health, psychological, and reproductive consequences of partner violence, broad cooperation between governments, communities, health professionals, and the media is necessary.

RNAi therapy targeting coronavirus genomes, pulmonary delivery strategies and design principles: A review.

International journal of biological macromolecules, 341(Pt 2):150223 pii:S0141-8130(26)00149-2 [Epub ahead of print].

With the persistent global outbreak of Coronavirus Disease 2019 (COVID-19), the development of effective antiviral strategies has become a top priority in public health. RNA interference (RNAi), an effective gene-silencing technique, presents a novel therapeutic approach to combat coronavirus replication. RNA interference (RNAi) is a potent gene-silencing approach that offers a therapeutic route to suppress coronavirus replication. Clinical translation of small interfering RNA (siRNA), however, faces substantial obstacles, notably cross-strain universality, off-target effects, and targeted delivery. This review summarizes recent advances in RNAi-mediated inhibition of coronaviruses at the genomic level, emphasizing RNAi applications to impede SARS-CoV-2 replication and transmission. By evaluating RNAi strategies aimed at specific viral components-RNA-dependent RNA polymerase (RdRp), spike protein (S), envelope protein (E), membrane protein (M), nucleocapsid protein (N), and other essential genes-we illustrate the distinct specificity and efficacy of RNAi across binding sites and identify candidate universal targets for human-transmitted coronaviruses. We also assess the strengths and limitations of delivery platforms, including liposomes, polymers, nanoparticles, and viral vectors. Finally, we highlight inhalation-based and other targeted delivery approaches as promising routes for siRNA therapeutics against COVID-19 and other pulmonary diseases. Advances in gene editing and nanotechnology continue to broaden the prospects for effective siRNA delivery.

The emergence of JN.1 variant resurgent COVID-19 wave in India and South Asia is a global public health concern.

Journal of infection and public health, 19(3):103146 pii:S1876-0341(26)00018-3 [Epub ahead of print].

The emergence of the JN.1 variant of SARS-CoV-2 has heightened global health concerns. Here, we aimed to evaluate viral characteristics, epidemiology, transmissibility, infectivity, immune evasion, effectiveness of current antiviral therapies, immunization options, genomic surveillance and public awareness against the stealthy JN.1. We searched across key databases to identify recent insights regarding JN.1 variant. This review provides a comprehensive overview of the virological characteristics and public health implications. Early genomic analyses reveal notable mutations in the spike protein, which may enhance viral transmissibility and immune escape. The findings indicate JN.1 to exhibit greater infectivity and enhanced ability to circumvent immune defenses attributable to one mutation identified as L455S. Public health agencies worldwide are enhancing monitoring, genomic surveillance, data sharing, revising containment strategies, promoting booster vaccination campaigns Furthermore, it is imperative to promote public adherence and global collaboration in encouraging the practice of preventive strategies to mitigate potential threat posed by JN.1.

Obesity and Nutritional Vulnerability in long COVID: A Neuroinflammatory and Cognitive Perspective.

Current nutrition reports, 15(1):5.

PURPOSE OF REVIEW: To examine the interplay between obesity, nutritional vulnerability, and long COVID, with a particular focus on neuroinflammatory and cognitive outcomes. This review synthesizes emerging evidence on shared pathophysiological pathways and evaluates the therapeutic potential of dietary and weight management strategies.

RECENT FINDINGS: Cognitive symptoms such as brain fog and memory deficits are among the most persistent and disabling features of long COVID. Obesity is associated with more severe manifestations through pathways involving chronic systemic inflammation, compromised blood-brain barrier integrity, and neuroimmune dysregulation. Concurrently, malnutrition and poor diet quality including low intake of antioxidants, omega-3 fatty acids, and micronutrients may impair neuroplasticity and delay recovery. Interventions such as Mediterranean and ketogenic dietary patterns, as well as structured weight loss programs, show promise in reducing inflammation and improving cognitive outcomes. Obesity and suboptimal nutritional status amplify the neurocognitive burden of long COVID through shared pathophysiological mechanisms. Integrated care models that incorporate metabolic screening, nutritional assessment, and individualized dietary interventions may improve recovery trajectories. Public health strategies that address food quality, obesity prevention, and equitable access to nutrition care are essential for long-term resilience in the post-COVID era.

From breath to brain: influenza vaccination as a pragmatic strategy for dementia prevention.

Aging clinical and experimental research pii:10.1007/s40520-026-03323-5 [Epub ahead of print].

Aging populations require scalable strategies to delay or prevent dementia. Beyond the prevention of neurological injury associated with seasonal influenza, vaccination may help mitigate vascular and neuroinflammatory injury underlying cognitive impairment. Influenza infection can cause a marked short‑term increase in myocardial infarction risk, and acute infections have also been associated with transient increases in stroke risk. Experimental models show prolonged microglial activation and synaptic loss even from non-neurotropic strains - processes likely modulated by vaccination. Epidemiologic data consistently support this evidence; a 2023 meta-analysis, including observational studies, of ~ 2.09 million adults identified a 31% lower risk of incident dementia; US matched cohorts demonstrated 40% lower risk of Alzheimer's disease (absolute decrease 3.4%); Veterans Health data showed a 0.86 hazard ratio for dementia; and UK Biobank data showed lower risk for all-cause (0.83 h), and vascular dementia (0.58 h) with a dose-response association by vaccination term. Randomized trials suggest fewer adverse cardiovascular events in vaccine recipients giving even more biological plausibility to this concept. Despite that, prevention through influenza vaccination is not fully realized in older adults due to low levels of perceived risk, vaccine confidence, and variations in clinical practice guidance. This public health perspective reviews the physiopathological and epidemiological evidence in support of influenza vaccination as a pragmatic, dementia risk-modifying intervention within healthy aging strategies and encourages the inclusion of vaccination status in hospital discharge and chronic-care pathways, integration of cognitive outcomes in monitoring, and equity-centered research to eliminate barriers to behavioral and implementation.

Serum Calprotectin - What is the Scope of Clinical Application?.

Clinical laboratory, 72(1):.

BACKGROUND: Calprotectin (CLP), a heterodimer of S100A8 and S100A9, is a calcium-binding protein with key intracellular and extracellular roles, especially in inflammatory processes. Predominantly expressed by neutrophils and monocytes, CLP is released in response to infection or inflammation and serves as a potent antimicrobial and pro-inflammatory mediator.

METHODS: We performed a systematic search of electronic databases to identify studies evaluating serum CLP in inflammatory diseases.

RESULTS: Serum CLP levels are elevated in numerous inflammatory conditions, making it a valuable biomarker for disease activity, prognosis, and therapeutic monitoring. In rheumatoid arthritis (RA), CLP reflects disease severity more accurately than conventional markers like CRP and ESR, correlates with radiographic progression, and is strongly expressed at inflammation sites. In juvenile idiopathic arthritis (JIA), serum CLP levels are significantly higher in active, treatment-naïve patients and correlate well with clinical activity. In spondyloarthritis (SpA), especially ankylosing spondylitis, CLP levels tend to be elevated, though results vary among studies. In inflammatory bowel disease (IBD), CLP is proposed as a non-invasive marker for disease burden and response to treatment. It is especially useful in systemic inflammation assessment. Elevated CLP levels are also observed in psoriasis, Behçet's disease, ANCA-associated vasculitis, and preeclampsia. CLP has emerged as a promising prognostic marker in bacterial infection and coronavirus disease 2019 (COVID-19), with higher levels correlating with ICU admission and disease severity.

CONCLUSIONS: Serum CLP is a promising inflammatory biomarker, though disease specificity remains limited.

From ancient remedy to modern COVID-19 adjunct: a narrative review of mechanistic, in vitro, and clinical evidence on propolis.

Journal of complementary & integrative medicine [Epub ahead of print].

INTRODUCTION: Despite the global rollout of COVID-19 vaccines, limited access, vaccine hesitancy, and the emergence of viral variants continue to underscore the need for complementary antiviral strategies. Propolis, a resinous bee product widely used in traditional medicine, has attracted scientific interest due to its reported antiviral, anti-inflammatory, immunomodulatory, and antioxidant properties.

CONTENT: This narrative review examines the therapeutic potential of propolis as a candidate adjunctive treatment for COVID-19, focusing on mechanistic, in vitro, and clinical evidence. A comprehensive review was conducted using PubMed, Scopus, and Europe PMC (January 2020 to May 2025), covering molecular docking reports, in vitro assays, and human clinical studies evaluating propolis or its key constituents against SARS-CoV-2. In silico reports describe interactions of more than forty propolis constituents with key host and viral targets, providing mechanistic context. In vitro evidence demonstrates inhibition at entry and replication targets alongside attenuation of inflammatory signaling. Limited clinical data, spanning seven studies and two case reports, suggest milder symptoms and shorter hospital stays, with no serious adverse events observed.

SUMMARY AND OUTLOOK: Preclinical and early clinical evidence suggest propolis may be a useful adjunct in COVID-19 therapy. Large, placebo-controlled trials with well characterized and standardized extracts are needed to confirm efficacy and safety.

Microplastics and Nanoplastics as Carriers for Viral Transmission: Effects on Viral Properties, Infection, Immune Response, and Public Health.

Reviews in medical virology, 36(1):e70106.

The extensive use of plastics since the industrial revolution has raised significant environmental and health concerns. Despite their advantages in terms of durability, affordability, and ease of production, the accumulation of plastics has resulted in considerable pollution. The SARS-CoV-2 pandemic further exacerbated plastic consumption, particularly in medical supplies, intensifying the plastic waste crisis. The majority of plastics are not recycled and eventually degrade into microplastics (MPs) and nanoplastics (NPs), which pose substantial risks to ecosystems and human health. MPs and NPs enter the body through inhalation, ingestion, or skin contact and have been found in biological samples such as blood, faeces, and lung fluids. Their presence has been linked to diseases affecting the lungs, cardiovascular system, and intestines, as well as cancer and viral infections. This review highlights how MPs and NPs contribute to the spread of infectious diseases by creating a habitat called the "plastisphere," which promotes microbial growth and serves as a reservoir for pathogens, emphasising their effects on viral persistence, infection dynamics, and immune modulation. Unlike previous reviews mainly focused on toxicological or microbiological aspects, this work integrates environmental, virological, and immunological evidence to outline how MPs/NPs may reshape virus-host interactions. By identifying critical knowledge gaps, such as the quantitative impact of MPs/NPs on viral stability and immune disruption, this review provides a background for future experimental and epidemiological research. This value-added perspective not only advances scientific understanding but also supports policy development in waste management.

Navigating the Digital Landscape for Potential Use of Mental Health Apps in Clinical Practice: Scoping Review.

JMIR mental health, 13:e75640 pii:v13i1e75640.

BACKGROUND: The global demand for mental health services has significantly increased over the past decade, exacerbated by the COVID-19 pandemic. Digital resources, particularly smartphone apps, offer a flexible and scalable means of addressing the research-to-practice gap in mental health care. Clinicians play a crucial role in integrating these apps into mental health care, although practitioner-guided digital interventions have traditionally been considered more effective than stand-alone apps.

OBJECTIVE: This scoping review explored mental health practitioners' views on potential use or integration of smartphone apps into clinical practice. We asked, "What is known about how mental health practitioners view the integration of smartphone apps into their practice?" Further, this scoping review explored the factors that might influence integration of smartphone apps into practice, such as practitioner and client characteristics, app design and functionality, and practitioner views.

METHODS: We conducted a systematic search of 3 databases that yielded 38 studies published between 2018 and 2025, involving 1894 participants across various mental health disciplines, most predominantly psychologists and psychiatrists. Data were collected on practitioner and client characteristics, app functionality, and factors deemed important or influencing practitioners' opinions about app integration.

RESULTS: The included studies were most likely to explore use of apps outside the clinical session and focused on self-management apps for mental health monitoring and tracking, and for collecting data from the patient. Fewer studies explored use of apps within-session, or practitioner-guided apps. Practitioners prioritized app features aligned with the American Psychological Association's evaluation criteria, with practitioners prioritizing engagement and interoperability, but also noted the importance of training and resourcing to support integration.

CONCLUSIONS: While practitioners recognize the potential of apps in mental health care, integration into clinical practice remains limited. This study highlights the need for further research on practical implementation, clinical effectiveness, and practitioner training to facilitate the transition from potential to actual use of apps in mental health care settings. Recommendations include evaluating effectiveness of app integration through experimental studies and developing training modules to develop practitioners' digital competencies and confidence in app use.

Effect of non-invasive ventilation and high-flow nasal cannula on hospital mortality in COVID-19-induced acute respiratory failure: a meta-analysis.

Einstein (Sao Paulo, Brazil), 24:eRW0695 pii:S1679-45082026000101401.

BACKGROUND: Non-invasive respiratory support strategies, such as high-flow nasal cannula therapy and non-invasive ventilation, were widely employed during the coronavirus disease 2019 (COVID-19) pandemic, yet their comparative effectiveness remains uncertain.

OBJECTIVE: To compare the effects of high-flow nasal cannula therapy, non-invasive ventilation, and conventional oxygen therapy on intubation rates and hospital mortality in adults with COVID-19-related acute respiratory failure.

METHODS: A systematic review and meta-analysis was conducted following PRISMA and Cochrane guidelines, with searches performed in nine databases for publications up to May 2023. Eligible studies were those on adults (≥18 years) with confirmed severe acute respiratory syndrome coronavirus 2 infection and that included intubation and mortality as primary outcomes. Risk of bias was assessed using the National Institutes of Health Quality Assessment Tool for Observational Cohorts and the Cochrane Risk of Bias tool. Pooled results were reported as odds ratios (ORs) with 95% confidence intervals (95%CIs).

RESULTS: Forty-one studies were included in the review and ten in the meta-analysis (2,843 patients). High-flow nasal cannula therapy did not differ from non-invasive ventilation in terms of the intubation rate (OR=1.07, 95%CI=0.89-1.29, p=0.45) but was superior to oxygen therapy (OR=0.79, 95%CI=0.64-0.97, p=0.02). High-flow nasal cannula therapy was also associated with lower mortality than non-invasive ventilation (OR=0.62, 95%CI=0.51-0.76, p<0.0001) but did not differ from oxygen therapy (OR=1.06, 95%CI=0.84-1.33, p=0.64). Substantial heterogeneity was observed in the subgroup analyses (I2=64%-90%).

INTERPRETATION: High-flow nasal cannula therapy may reduce the need for intubation compared with oxygen therapy and may lower the hospital mortality rate compared with non-invasive ventilation. However, heterogeneity in the studies suggests that patient-specific factors and disease severity may influence outcomes.

CONCLUSION: High-flow nasal cannula therapy shows potential benefits over oxygen therapy and non-invasive ventilation for COVID-19-related acute respiratory failure, particularly in the mortality rate. Clinical use of these therapies should be context-specific, given the need for cautious interpretation of our results and for further high-quality trials.

Factors associated with suicidal ideation in healthcare personnel: a systematic review.

Frontiers in psychology, 16:1717231.

AIM: This paper investigates suicidal ideation among healthcare professionals, a growing concern that affects their mental well-being and the quality of healthcare delivery. The study aims to identify key risk factors, such as work-related stress, exposure to death, and lack of institutional support, that contribute to suicidal ideation in this population. It also explores protective factors, including resilience, social support, and institutional resources, that may mitigate these risks.

METHOD: A systematic review was conducted on studies published between 2020 and 2024. The literature search spanned databases such as PubMed, Scopus, Web of Science, PsycINFO, Dialnet, and Scielo. The review followed the PRISMA guidelines to ensure thoroughness and transparency in study selection. To assess the quality of the included studies, standardized tools like the Newcastle-Ottawa Scale were applied.

RESULTS: The review identified that the COVID-19 pandemic has intensified factors leading to suicidal ideation among healthcare professionals, with a notable increase in prevalence during this period. Identified risk factors included high levels of occupational stress, frequent exposure to death and suffering, and insufficient institutional support. Conversely, protective factors like resilience, social support, and access to institutional resources were found to reduce susceptibility to suicidal ideation.

CONCLUSION: The findings highlight an urgent need for comprehensive prevention strategies and support programs targeting healthcare personnel. Recommendations for interventions span individual, organizational, and public policy levels. Enhancing resilience and providing institutional support could be crucial steps in reducing the incidence of suicidal ideation in this vulnerable group, ultimately improving both their mental health and the quality of healthcare services.

P2Y14 receptor activation and neutrophil signaling: linking inflammation to systemic pathophysiology.

Purinergic signalling, 22(1):5.

Neutrophils are essential effector cells of the innate immune system, acting as the first line of defense against infection and tissue injury. Among the purinergic receptors expressed in these cells, P2Y14 has gained increasing attention in recent years for its role in modulating neutrophil recruitment and activation in inflammatory contexts. This receptor is activated mainly by uridine diphosphoglucose (UDP-glucose) and other UDP-sugars released during cellular stress or damage. Through the activation of G protein-coupled pathways, particularly via Gi/o and RhoA signaling, P2Y14 influences key neutrophil functions, including chemotaxis, cytoskeletal rearrangements, and oxidative responses. Despite its pro-inflammatory potential, and the increasing amount of literature data in recent years, P2Y14's complete physiological and pathological roles remain underexplored. Literature data also highlight its involvement in diseases like glioblastoma and COVID-19, where, due to increased neutrophil infiltration, it exacerbates inflammation, tissue damage, and stress. Therefore, targeting P2Y14 may be a promising strategy to modulate neutrophil chemotaxis and mitigate unwanted harmful inflammatory responses. This review discusses the characteristics and signaling mechanisms of P2Y14 in neutrophils, as well as the relevant implications of this pathway for neutrophil function.

Sudden Cardiac Arrest in Athletes.

The New England journal of medicine, 394(3):268-280.

The incidence of sudden cardiac arrest in athletes varies according to age, race and ethnic group, sex, sport, and social determinants of health. The common causes of sudden cardiac arrest include cardiomyopathies, electrical disorders, coronary-artery anomalies, and other cardiac structural abnormalities. There has not been an increase in the incidence of sudden cardiac arrest in athletes during the time frame of the coronavirus disease 2019 (Covid-19) pandemic. Primary prevention is based on cardiovascular screening before participation, and secondary prevention on implementation of emergency action plans. Diagnostic evaluation of athletes who survive sudden cardiac arrest should mirror that of age-matched nonathletes, with additional sport-specific considerations, and should be performed by medical professionals with expertise in the interpretation of test results in the context of athletic adaptation. An increasing body of evidence indicates that many athletes can return to play after disease-specific treatment, without an increase in risk, and professional societies now consider return to participation in sports to be reasonable or appropriate through shared decision making for numerous cardiac conditions.

Comparative analysis of point-of-care diagnostic techniques for respiratory infectious diseases. Lessons we learned from the COVID-19 pandemic and future consideration on more competent alternatives.

Pathogens and global health [Epub ahead of print].

Our unpreparedness in responding to the prompt emergence of COVID-19 in its early stage of outbreak, especially the lack of rapid and early diagnostic techniques for mass screening which should have been prioritized, contributed to the virus' spread alongside other factors. This article provides an overview of the common diagnostic techniques with special focus on the reported and/or authorized point-of-care methods for early COVID-19 diagnosis, including lateral flow assays and localized surface plasmon resonance-based approaches. The inherent limitations of these techniques are critically examined. We then propose a potentially more competent alternative, i.e. direct detection of viral particles with aptamer-conjugated gold nanoparticles in liquid solution in combination with noninvasive breath sampling or saliva sampling, for further improvement in early diagnostic capability for infectious respiratory diseases like COVID-19. In addition, an integration of air sampling with in-situ direct colorimetric detection of viral particles could represent a potential option for airborne virus detection, thus minimizing the transmission of infectious diseases and their impact on the economy and life in the future.

Nitric Oxide at the Nexus of ACE2 Biology and COVID-19: Implications for Cardiovascular and Neurodegenerative Comorbidities.

Physiological research, 74(Suppl 2):S171-S184.

SARS-CoV-2 engages ACE2 for cell entry, perturbing the counter-regulatory ACE2/Ang-(1-7)/Mas axis and shifting the renin angiotensin system toward ACE/Ang II/AT1 signaling, with a concomitant reduction in nitric oxide (NO) bioavailability. NO sits at the crossroads of these pathways, acting both as an antiviral modulator of spike-ACE2 interactions and as a downstream mediator of Mas-dependent endothelial protection. This review summarizes evidence on NO across three layers: (i) viral entry (S nitrosylation of spike/ACE2, protease modulation), (ii) cardiovascular comorbidities (hypertension, obesity, diabetes) where ACE2 downregulation impairs endothelial NO synthase (eNOS)-dependent NO production and promotes thrombosis and microvascular dysfunction, and (iii) neurovascular/ neurodegenerative sequelae, in which renin-angiotensin-aldosterone system (RAAS) dysregulation along with imbalance between protective eNOS/nNOS and inflammatory iNOS fosters blood-brain barrier disruption, microthrombosis, and cognitive impairment. Shared mechanisms - endotheliitis, microvascular dysfunction, and neuroinflammation may explain convergent risks for cardiac injury and cognitive decline in long COVID-19. Putative therapeutic strategies may include restoring physiological NO (via Mas agonism, Ang-(1-7), inhibition of Ang 1-7 degradation and recombinant ACE2), pulmonary-selective inhaled NO, hybrid S nitrosylated agents, and selective attenuation of iNOS/peroxynitrite alongside endothelial support. Targeted modulation - enhancing eNOS/nNOS while constraining iNOS offers a unified framework to mitigate both cardiovascular and neurodegenerative consequences of COVID-19.

Application of the humanized mouse model in research into SARS-CoV-2 infection (Review).

Medicine international, 6(1):9.

The coronavirus disease 2019 (COVID-19) pandemic triggered by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has had a profound impact on global public health. The complexity of its pathogenic mechanisms and host interactions urgently requires high-fidelity animal models to support research. Humanized mouse models break the species barrier through gene editing and immune reconstitution technologies, providing a key tool to simulate human infection characteristics and pathological processes. A number of studies have reported the application of humanized mouse models in the fields of COVID-19 research, such as SARS-CoV-2 pathogenesis, anti-SARS-CoV-2 drug discovery and vaccine development, etc. The present review aimed to systematically document the latest advances in the application of humanized mouse models based on different construction strategies, such as receptor humanization, immune system humanization and composite humanization. These models have not only elucidated the pathogenicity differences and immune escape mechanisms of SARS-CoV-2 variants, but have also validated the efficacy of broad-spectrum anti-SARS-CoV-2 strategies, including angiotensin-converting enzyme 2-targeted therapies, antibody cocktail regimens and mucosal vaccines. Additionally, humanized mouse models have played a pivotal role in investigating the mechanisms underlying long COVID. By revealing the multi-system pathogenic mechanisms of pulmonary fibrosis, neurodegeneration and intestinal microbiota dysregulation, these models provide a theoretical foundation for the development of targeted intervention strategies.

[Colchicine in Cardiology Practice: Use in Atrial Fibrillation, Inflammatory Diseases, Heart Failure, and Cardiac Complications of COVID-19].

Kardiologiia, 65(12):113-120.

Inflammation is an integral part of the pathophysiological processes leading to damage or regeneration of the heart and blood vessels. Interest to the "inflammatory theory" of cardiovascular disease is once again at the peak of scientific research, driven by the discovery of new laboratory and instrumental methods, as well as the emergence of new cardiotropic viruses, including SARS-CoV-2. Colchicine, the most effective and safe drug used to modulate excessive inflammation in heart disease, is included in guidelines for the treatment of perimyocarditis and ischemic heart disease with a high class of evidence. Furthermore, it has been shown that colchicine can reduce the innate and, to some extent, the acquired immune response. Thereby, colchicine can affect the arrhythmia substrate and trigger, the inflammatory component of chronic myocardial degeneration during the development of heart failure. Also, colchicine can exert specific and nonspecific positive effects on the cardiac complications of COVID-19. The use of this medication in cardiology practice is limited by insufficient awareness of its indications and side effects, while in rheumatology practice, it is limited by a lack of knowledge about colchicine's additional properties in cardiac conditions. This review summarizes medical studies available online that assess the clinical efficacy of colchicine medicines in the conditions not yet included in official guidelines for its use, such as atrial fibrillation, autoinflammatory diseases, heart failure, and cardiac complications of COVID-19. For each of these conditions, colchicine can be used with the consideration of specific indications. This article includes published in the internet medical studies, abstracts, and meta-analyses with no publication date restrictions up to July 2025. The PubMed, ScienceDirect, Google Scholar, and CENTRAL databases were used to review 520 literature sources that described the clinical efficacy of colchicine medicines and the heterogeneity of its effects across different regimens for various cardiovascular diseases.

Data-driven strategies for model-informed decision-making during the COVID-19 pandemic: a systematic review.

BMJ open, 16(1):e107660.

OBJECTIVES: To systematically review data-driven modelling studies that evaluated the effectiveness of interventions implemented during the COVID-19 pandemic and to identify which measures were most frequently reported as effective in controlling disease spread.

DESIGN: Systematic review of modelling studies focused on data-driven, model-informed decision-making for COVID-19 interventions.

DATA SOURCES: A comprehensive literature search was conducted in PubMed, Web of Science and Embase, covering publications from 1 January 2020 to 16 October 2024.

ELIGIBILITY CRITERIA: Studies were included if they: (1) used real-world data; (2) had sufficient sample sizes and (3) assessed at least one intervention with measurable outcomes.Meta-analyses and purely theoretical modelling studies were excluded. Papers were further filtered using a structured screening process to ensure empirical and intervention-based modelling.

DATA EXTRACTION AND SYNTHESIS: Data were extracted from eligible studies and categorised according to modelling approaches, data sources, intervention types and reported effectiveness. Descriptive synthesis was performed to summarise modelling trends and intervention performance. Studies were classified into major intervention categories, including tracing, testing and isolation (TTI); physical and social distancing (PSD); vaccination; lockdowns; mask-wearing; home office or stay-at-home (HOSH) and health infrastructure enhancement (HIE).

RESULTS: Out of 2297 studies identified, 126 met inclusion criteria. Compartmental models were the most frequently used approach, primarily relying on case and death counts to assess intervention impact. The most commonly reported effective interventions were TTI, PSD, vaccination, lockdowns, mask-wearing and HOSH. When considering effectiveness relative to study frequency, the top six interventions were TTI, HOSH, mask-wearing, HIE, PSD and lockdowns. The relatively lower representation of vaccination reflects that most included studies were conducted during the early stages of the pandemic, before widespread vaccine rollout and availability of empirical vaccination data.

CONCLUSIONS: This review highlights the critical role of data-driven models in guiding COVID-19 response strategies. Evidence supports the combined effectiveness of non-pharmaceutical interventions, robust testing and tracing systems and health infrastructure strengthening. Real-world impact, however, remains dependent on local healthcare capacity, socioeconomic conditions and cultural contexts. Continued research is essential to refine adaptive modelling approaches and strengthen preparedness for future public health emergencies.

The main protease (Mpro) from coronaviruses represents an attractive therapeutic target for antiviral development. The fluorescence resonance energy transfer (FRET) assay is widely used for high-throughput screening (HTS) of Mpro inhibitors, but there has been a significant increase in false positives stemming from flawed assay design in previous studies. Here, we provide an overview of the FRET assay, discuss the key points of this method design, and highlight the corresponding solutions. We hope that this issue should receive increased attention from researchers.

Utilization of mental health services during the first year of the COVID-19 pandemic - a systematic review and meta-analysis.

European psychiatry : the journal of the Association of European Psychiatrists, 69(1):e10.

BACKGROUND: The COVID-19 pandemic presented significant challenges to infectious disease management and mental health services (MHS). Service demand and delivery changed due to fear of infection, economic hardships, and the psychological effects of protective measures. This systematic review with meta-analysis aims to quantify these impacts on different mental health service settings.

METHODS: Comprehensive searches were conducted in PubMed, Embase, and PsycINFO, focusing on studies published from the initial outbreak of COVID-19, starting in November 2019. Studies were included comparing the utilization of mental health inpatient, emergency department (ED), and outpatient services (including telemedicine and medication prescriptions) before and during the COVID-19 pandemic. A random-effects model was employed to estimate pooled effects, with study quality assessed using a modified Newcastle-Ottawa Scale.

RESULTS: Among 128 studies, significant decreases in utilization were observed during the initial phase of the pandemic for inpatient services (RR: 0.75, 95% CI: 0.67 to 0.85) and ED visits (RR: 0.87, 95% CI: 0.69 to 1.10). Outpatient services showed a similar decline (RR: 0.78, 95% CI: 0.66 to 0.92), while no significant change was found in psychotropic medication prescriptions (RR: 0.90, CI: 0.77 to 1.05). In contrast, telemedicine utilization increased significantly (RR: 7.57, 95% CI: 3.63 to 15.77).

CONCLUSIONS: The findings reveal substantial shifts in mental health service utilization during the pandemic, with the largest reductions in inpatient services and significant increases in telemedicine use. These results emphasize the need for flexible healthcare models. Further research is essential to evaluate the consequences of reduced MHS utilization.

SARS-CoV-2 wastewater genomic surveillance: approaches, challenges, and opportunities.

Genome biology, 27(1):1.

Wastewater-based genomic surveillance (WWGS) has proven effective for monitoring SARS-CoV-2 and other viruses within communities. It enables rapid detection of known and emerging mutations and provides insights into circulating lineages. Despite its advantages, WWGS faces challenges in sample processing and computational analysis, particularly in distinguishing similar lineages and identifying novel ones. Recent methods for wastewater sequencing (WWS) analysis remain largely untested amid declining clinical surveillance and ongoing viral evolution. This review examines opportunities and limitations of WWGS, focusing on sample preparation, sequencing technologies, and bioinformatics approaches, and highlights its potential to strengthen public health monitoring systems.

Exploring molecular interactions of drugs in different biologically active solvents: A comprehensive review for safe and efficient drug delivery systems.

International journal of biological macromolecules, 340(Pt 2):150197.

In this review, the interactions between drugs and biologically active solvents have been extensively investigated due to their importance in optimizing pharmaceutical formulation performance for effective therapeutic efficacy and safe drug delivery. These interactions determine the molecular stability, reactivity and solubility of drugs in different biocompatible solvents. The knowledge about their absorption, distribution, metabolism, transport and bioavailability can be enhanced from their molecular interactions data. There have been reports of improved solubility and stability of drugs like metformin hydrochloride and hydralazine hydrochloride in aqueous solutions of carbohydrates and amino acids, which has an immediate effect on their bioavailability and treatment efficacy. Moreover, the COVID-19 pandemic has reestablished the importance of this review, as some drugs were clinically approved after proving their activity and efficacy during this phase. The antivirals favipiravir, remdesivir and two repurposed drugs, antimalarial hydroxychloroquine and metabolic inhibitor 2-deoxy-d-glucose (2-DG) were approved during this phase based on their available physicochemical data. These results established the clinical efficacy and dependency of drugs on their solvation environment, highlighting the pharmacological importance of studying molecular interactions in addition to their theoretical significance. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) model was adopted to conduct this systematic review, covering scientific articles from 2000 to 2025 to ensure a careful evaluation of recent advancements. This review focuses on the molecular interactions of various drugs with different biological solvent systems, using physicochemical, spectroscopic, and computational methods. It critically examines drug-solvent interactions by specifying quantitative physicochemical (free energy changes), spectral (binding constant) and computational metrics (binding affinity). This integrated approach provides a novel molecular-level insight into the structural, solvation, and interaction behavior of drugs under physiological conditions. The integration of molecular dynamics, artificial intelligence/machine learning tools, and experimental validation represents a prospective approach for addressing current limitations, contributing to the development of precision in drug delivery strategies for personalized medications. This review could be substantial for biochemical and medicinal sectors with important implications in formulation, stability, bioavailability, and solubility of drugs in clinical pharmacology. The outcome may provide an important basis for advanced research in future, serving the scientific community in understanding pharmacokinetics and pharmacodynamics of drug interactions. This can further strengthen the advanced research in future, involving drug-solvent interactions, which ultimately improves the safety, treatment efficacy and delivery performance of the drugs.

Rural Active Living: A Call to Action 2.0, 10-Year Review and Recommendations to Advance the Field.

Journal of public health management and practice : JPHMP, 32(2):197-213.

CONTEXT OBJECTIVE: Written a decade ago, the 2015 Rural Active Living: A Call to Action (published in 2016) described rural-specific efforts in the fields of active living and physical activity (PA) and identified 8 recommendations to guide rural active living research and practice. Given that rural populations continue to experience a higher burden of PA-related chronic health conditions, the objective of this review was to revisit the 8 Rural Active Living Calls to Action, reassess the evidence base, summarize advances in each area, and identify emerging areas that warrant examination or further study.

METHODS: We leveraged expertise from researchers and practitioners within the CDC-funded Physical Activity Policy Research and Evaluation Network Rural Active Living Workgroup and reviewed literature published since the original call to action. Teams were formed for each of the original 8 calls to action. Each team reviewed the literature, synthesized findings, and developed recommendations for future research.

RESULTS: Academic and practice-based progress was evident across multiple of the original calls to action. Despite these findings, the need persists for rural-specific national surveillance data scaled to small geographies (census tract and block group) that accounts for differences within and across rural communities, various forms of rural governance, and how these factors interplay with active living opportunities. Six emerging areas of research (best practices, social issues, COVID-19 effects, collaboration, implementation science, and implications of rural health-related funding changes) are discussed and warrant further study.

CONCLUSIONS: In summarizing progress since the original Call to Action, we recommend strategies to continue advancing rural active living and identify emerging focus areas.

Prevalence of burnout among Brazilian Army soldiers during the COVID-19 pandemic: a cross-sectional analysis.

Revista brasileira de medicina do trabalho : publicacao oficial da Associacao Nacional de Medicina do Trabalho-ANAMT, 23(4):e20251467.

INTRODUCTION: The COVID-19 pandemic significantly impacted the mental health of frontline workers, including military personnel.

OBJECTIVES: To determine the prevalence of burnout syndrome among Brazilian Army personnel during the pandemic and identify associated predictive variables.

METHODS: A cross-sectional study was conducted with 602 volunteer military personnel in the city of Santa Maria, Brazil. The Maslach Burnout Inventory was used to assess burnout syndrome, defined by high levels of emotional exhaustion, depersonalization, or low personal accomplishment. Logistic regression was performed to identify associated factors.

RESULTS: The prevalence ofburnout syndrome was 48.7%. High levels of emotional exhaustion, depersonalization, and low personal accomplishment were found in 53.8%, 58.4%, and 27.0% of participants, respectively. Emotional exhaustion was more common in those with over 10 years of service (p = 0.001), higher rank (p < 0.001), and age > 40 years (p = 0.008). Low personal accomplishment was associated with lower rank (p = 0.007) and administrative duties (p = 0.032).

CONCLUSIONS: Burnout syndrome was highly prevalent among military personnel in Brazil during the pandemic, with findings similar to those observed in other professional groups.

Efficacy and Safety of Pirfenidone for Mitigation of Interstitial Lung Abnormalities in COVID-19 Patients: A Meta-Analysis.

Canadian respiratory journal, 2026:8812779.

BACKGROUND: Although post-COVID-19 interstitial lung abnormalities (ILAs) are common, the use of antifibrotic agents to prevent their onset and progression is controversial. We aimed to investigate the effectiveness and safety of pirfenidone to mitigate the onset and progression of ILAs in patients with severe COVID-19.

METHODS: We systematically searched literature published before July 21, 2025, from PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, China Biology Medicine, Weipu, and Wanfang databases, without language limitation. Randomized controlled trials and cohort studies that evaluated the effect of pirfenidone on COVID-19-induced ILAs were included. Risk of bias was determined using the Revised Cochrane Randomized Trial Risk Bias Tool Version 2 and the Newcastle-Ottawa Scale. The efficacy and safety of pirfenidone for ILAs in COVID-19 were analyzed by Review Manager 5.4 software.

RESULTS: Eight studies were included, comprising 335 patients in pirfenidone treatment groups and 302 controls. Risk of bias ranged from low to moderate. Pirfenidone significantly decreased chest high-resolution CT (HRCT) scores during early- and late-stage COVID-19 and significantly improved forced expiratory volume in 1 s, especially in late-stage COVID-19. Pirfenidone treatment was associated with statistically nonsignificant trends toward improved forced vital capacity and decreased all-cause mortality. Furthermore, HRCT scores, pulmonary function, and inflammatory cytokine levels following pirfenidone treatment were superior to those obtained after glucocorticoid therapy. The incidence of gastrointestinal adverse events was higher in the pirfenidone than the control group, but no serious adverse events or fatalities occurred.

CONCLUSION: Pirfenidone therapy may mitigate ILAs and preserve pulmonary function among survivors of COVID-19 pneumonia. Furthermore, pirfenidone exhibited acceptable safety and tolerability profiles.

Novel insights into diagnosis and management of hyperreactivity: a narrative review.

Journal of thoracic disease, 17(12):11429-11453.

BACKGROUND AND OBJECTIVE: Hyperreactivity (HR) refers to an exaggerated biological response to a given stimulus that is within the normal physiological range, resulting from a lowered activation threshold of the involved system or effector cells. It commonly occurs after surgery, lung transplantation, and coronavirus disease 2019 (COVID-19) infection but lacks a unified concept and systematic understanding. This review aims to elucidate the concept, mechanisms, and disease spectrum of HR as an independent clinical entity, systematically explore its roles in postoperative conditions, lung transplantation, and COVID-19, and develop a biomarker-based hierarchical management framework, thereby providing a new paradigm for its precise recognition and intervention.

METHODS: We systematically searched the PubMed, Web of Science, Scopus, and China National Knowledge Infrastructure databases for literature published from January 1, 1968, to November 1, 2025, including reviews, randomized controlled trials, and observational studies, human or animal studies related to HR mechanisms or clinical phenotypes, while excluding non-peer-reviewed materials such as case reports and conference abstracts.

KEY CONTENT AND FINDINGS: This study first proposes that HR arises from a four-dimensional imbalance across the nervous, endocrine, immune, and microenvironmental systems, characterized by thoroughness, early onset/persistence, and individual variability. The mechanisms underlying HR in postoperative, transplant-related, and COVID-19 conditions are systematically summarized, and a hierarchical, biomarker-based management framework is developed, highlighting the need for marker validation and trajectory modeling.

CONCLUSIONS: HR represents an independent clinical entity that transcends traditional disease boundaries. This review provides a new paradigm for its precise recognition and intervention and is expected to advance the conceptual and practical development of this field. Future research, clinical practice, and policy formulation should be individualized and mechanism-driven.

mRNA-Encoded antibodies as a next-generation therapeutic paradigm: a rapid and adaptive platform for the prevention and treatment of emerging and re-emerging infectious diseases - A critical review.

Immunologic research, 74(1):7.

Messenger RNA (mRNA)-encoded antibodies represent a transformative therapeutic platform with the potential to rapidly combat emerging infectious diseases by enabling in situ expression of potent neutralizing antibodies directly in the patient's body. Unlike conventional monoclonal antibody (mAb) therapies, which rely on labor-intensive and time-consuming cell culture production, mRNA-encoded antibodies offer a faster, scalable, and cell-free approach that bypasses protein purification and cold-chain constraints. This strategy has demonstrated considerable promise during the COVID-19 pandemic, where Moderna's mRNA-1940, an mRNA-based neutralizing antibody targeting the SARS-CoV-2 spike protein, entered preclinical and early-phase trials within months of viral emergence, underscoring the potential for rapid response in outbreak settings. The platform leverages advances in nucleoside-modified mRNA, codon optimization, and lipid nanoparticle (LNP) delivery systems to achieve transient, high-level expression of functional antibodies with reduced innate immune activation. Beyond COVID-19, mRNA-encoded antibody approaches have been explored in preclinical models of Zika virus, Ebola virus, and rabies, where a single intramuscular dose provided prophylactic and therapeutic benefits in animal models. As the world faces recurrent viral threats, the development of mRNA-encoded antibodies as a plug-and-play system offers a compelling, adaptable, and clinically feasible strategy for infectious disease preparedness. This review explores the mechanistic foundation, delivery technologies, translational progress, case studies, safety considerations, and future clinical potential of mRNA-encoded antibodies in combating both pandemic and endemic infections.

Advancements in nanotrap technology for the prevention, diagnosis and treatment of infectious diseases.

Nanomedicine (London, England) [Epub ahead of print].

Nanotraps are particles designed to capture and concentrate target molecules and have numerous applications in infectious diseases. This review outlines how nanotrap technologies may improve the detection and treatment of bacterial and viral pathogens, including Mycobacterium tuberculosis, Borrelia burgdorferi, Yersinia pestis, HIV, SARS-CoV-2, and others. Nanotraps can enhance the sensitivity of diagnostic tools and support treatment by neutralizing bacterial toxins, capturing inflammatory mediators, and preserving viral proteins for detection. Nanotraps have also been investigated for vaccine development. While results from in vitro and in vivo models are encouraging, there is significant room for further research regarding safety and other unexplored applications of these technologies. Nanotraps offer a flexible platform with the potential to improve how we diagnose and manage a multitude of infectious diseases.

The Emergence and Characterization of SARS-CoV-2 Variant XFG ("Stratus"): Comparative Virological, Epidemiological, and Public-Health Perspectives.

Journal of epidemiology and global health, 16(1):8.

BACKGROUND: SARS-CoV-2 continues to diversify under the selective pressure of population immunity, with recombination increasingly contributing to the emergence of new lineages. The recombinant lineage XFG (“Stratus”), detected in early 2025, has attracted attention because it combines genetic features from distinct Omicron descendants and has expanded across multiple regions.SARS-CoV-2 continues to diversify under the selective pressure of population immunity, with recombination increasingly contributing to the emergence of new lineages. The recombinant lineage XFG (“Stratus”), detected in early 2025, has attracted attention because it combines genetic features from distinct Omicron descendants and has expanded across multiple regions.

OBJECTIVE: To synthesize the current virological, immunological, epidemiological, and clinical evidence on XFG, and to contextualize its public-health significance through comparison with the closely related Omicron-derived lineages JN.1 and NB.1.8.1.…

APPROACH: This narrative review integrates available molecular and immune data with surveillance observations and emerging clinical reports, translating technical findings into implications that are relevant for healthcare systems and the people they serve.

KEY FINDINGS: Across available datasets, XFG shows modest immune escape and a moderate growth advantage, yet there is no signal of increased clinical severity compared with recent Omicron sublineages. Current evidence supports the continued effectiveness of vaccines and antivirals, reinforcing that incremental viral adaptation is compatible with stable clinical outcomes in immunologically experienced populations.

CONCLUSIONS: XFG exemplifies ongoing, “quiet” SARS-CoV-2 evolution—more consistent with antigenic fine-tuning than a shift toward greater virulence. For individuals, the practical message remains steady: stay updated with vaccination when eligible and seek timely care when at higher risk. For health systems, sustained genomic surveillance, targeted protection of vulnerable groups, and measured risk communication remain central to resilient coexistence with SARS-CoV-2.

Psychological distress in Spanish-speaking countries during the COVID-19 pandemic: A systematic review and meta-analysis.

Medicine, 105(2):e47062.

BACKGROUND: Psychological distress (PD) has increased significantly during the coronavirus disease 2019 (COVID-19) pandemic. In Spanish-speaking countries, with their cultural, social, and economic diversity, this phenomenon has become particularly relevant and has been aggravated by factors such as socioeconomic inequalities and unequal access to mental health services. The aim of this systematic review was to consolidate the available knowledge on PD in Spanish-speaking population groups by assessing both the prevalence of symptoms and the associated factors in different demographic groups and geographic contexts, during the COVID-19 pandemic.

METHODS: A systematic review following the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) statement was conducted in the Web of Science, PubMed, and Scopus electronic databases in January 2025. The search included studies published from the beginning of the pandemic until May 2023. The Joanna Briggs Institute's critical assessment tool was used to evaluate the chosen studies' methodological quality.

RESULTS: A total of 53 studies were included in the review, which involved research conducted in Spain, Peru, Chile, Ecuador, Argentina, and Colombia. The results revealed a high prevalence of PD in these countries, especially among healthcare workers, women, and young people. The assessment methods used included the General Health Questionnaire (GHQ, GHQ-12, and GHQ-28 versions), the Kessler scale (K-6 and K-10 versions), and the 90-symptom checklist questionnaire (SCL-90-R), that allowed obtaining various dimensions of PD. The studies also highlighted the importance of the sense of coherence and work engagement as protective factors.

CONCLUSIONS: In the COVID-19 pandemic, PD was analyzed to be severe in Spanish-speaking countries, pointing to the need for specific and culturally adapted interventions to address this public mental health crisis. This is why public health policies must focus on the prevention and treatment of PD, with special attention to the most vulnerable groups.

Surgical Timing and Safety of Breast Cancer Operations After COVID-19: A Prospective-Only Meta-Analysis of Cohort Studies.

Journal of clinical medicine, 15(1):.

Background: The COVID-19 pandemic raised uncertainties regarding the safe timing of breast cancer surgery after SARS-CoV-2 infection, and robust prospective evidence has remained limited. Methods: We conducted a systematic review and meta-analysis of prospective cohort studies (2020-2024) investigating postoperative outcomes in breast cancer patients with confirmed SARS-CoV-2 infection ≤90 days before surgery versus contemporaneous non-infected controls treated at the same institutions and in the same period. PROSPERO CRD420251174613. Random-effects models (DerSimonian-Laird with Hartung-Knapp adjustment) were used to pool odds ratios (ORs) and 95% confidence intervals (CIs). Study quality was assessed with the Newcastle-Ottawa Scale, and certainty of evidence was rated using GRADE. Results: Twelve prospective cohort studies, including 7812 patients, compared breast cancer surgery after recent confirmed SARS-CoV-2 infection over 90 days with contemporaneous non-infected controls treated at the same centres. Overall, recent infection was associated with higher 30-day postoperative complications (Clavien-Dindo ≥ II) compared to. non-infected patients (OR 2.01, 95% CI 1.44-2.81) and increased venous thromboembolism (3.6%vs. 1.2%; OR 3.12, 95% CI 1.29-7.55). Early surgery 14 days after infection carried the highest risk of complications (OR 4.38, 95 CI 2.31-8.30), whereas operations performed ≥6 weeks yielded outcomes comparable to non-infected controls (OR 1.03, 95 CI 0.81-1.31); 30-day mortality remained very low (0.3). Conclusions: Breast cancer surgery after SARS-CoV-2 infection is associated with excess perioperative risk only when performed within the first two weeks. Delaying surgery to approximately six weeks minimises complications and VTE without compromising short-term safety.

High-Flow Nasal Cannula Outside the ICU: A Systematic Review and Meta-Analysis.

Journal of clinical medicine, 15(1):.

Background: Use of high-flow nasal cannula (HFNC) expanded from ICUs to internal medicine/respiratory wards during and after the COVID-19 pandemic, but safety and effectiveness in non-ICU settings remain uncertain. Methods: We performed a systematic review and meta-analysis of adults (≥18 years) initiated on HFNC in non-ICU wards. Primary outcomes were in-hospital (or 28-day) mortality and ICU transfer; where available, we compared mortality for HFNC vs. conventional oxygen therapy (COT) in do-not-intubate (DNI) cohorts. Observational studies and trials were eligible. Random-effects models synthesized proportions and risk ratios; risk of bias (ROBINS-I/RoB 2) and certainty (GRADE) were assessed. Results: Ten studies met the inclusion criteria for any-ward HFNC; subsets contributed data to pooled analyses. Across all non-ICU wards (general wards plus step-up IMCU/HDU), pooled mortality was 14.0% (95% CI 4.6-35.5; I[2] ≈ 92%). Pooled ICU transfer after ward/step-up HFNC start was 20.0% (95% CI 6.3-48.1; I[2] ≈ 97%). Restricted to internal medicine/respiratory wards, pooled mortality was 19.8% (95% CI 7.1-44.2; I[2] ≈ 95%) and ICU transfer 31.2% (95% CI 9.9-65.0; I[2] ≈ 97%). In step-up units (IMCU/HDU), ICU transfer appeared lower and less variable (22.0% [95% CI 16.5-28.8]; I[2] ≈ 10%), suggesting environment-dependent outcomes. In a multicenter DNI COVID-19 cohort, HFNC vs. COT showed no clear mortality difference (RR ≈ 0.90, 95% CI 0.75-1.08; adjusted OR ≈ 0.72, 95% CI 0.34-1.54). Certainty of evidence for all critical outcomes was very low due to observational design, high inconsistency, and imprecision. Conclusions: HFNC outside the ICU is feasible, but it is related to nontrivial mortality and frequent escalation-particularly on general wards-while step-up units demonstrate more reproducible trajectories. Outcomes appear strongly conditioned by care environment, staffing, monitoring, and escalation pathways. Given very low certainty and substantial heterogeneity, institutions should pair ward HFNC with protocolized reassessment and rapid response/ICU outreach, and future research should prospectively compare ward HFNC pathways against optimized COT/NIV using standardized outcomes.

Hospital Influenza Outbreak Management in the Post-COVID Era: A Narrative Review of Evolving Practices and Feasibility Considerations.

Healthcare (Basel, Switzerland), 14(1):.

Background: Hospital-acquired influenza remains a persistent threat that amplifies morbidity, mortality, length of stay, and operational strain, particularly among older and immunocompromised inpatients. The COVID-19 era reshaped control norms-normalizing N95 use during surges, ventilation improvements, and routine multiplex PCR-creating an opportunity to strengthen hospital outbreak management. Methods: We conducted a targeted narrative review of WHO/CDC/Infectious Diseases Society of America (IDSA) guidance and peer-reviewed studies (January 2015-August 2025), emphasizing adult inpatient care. This narrative review synthesizes recent evidence and discusses theoretical implications for practice, rather than establishing formal guidelines. Evidence was synthesized into pragmatic practice statements on detection, diagnostics, isolation/cohorting, antivirals, chemoprophylaxis, vaccination, surveillance, and communication. Results: Early recognition and test-based confirmation are pivotal. For inpatients, nucleic-acid amplification tests are preferred; negative antigen tests warrant PCR confirmation, and lower-respiratory specimens improve yield in severe disease. A practical outbreak threshold is ≥2 epidemiologically linked, laboratory-confirmed cases within 72 h on the same ward. Effective control may require immediate isolation or cohorting with dedicated staff, strict droplet/respiratory protection, and daily active surveillance. Early oseltamivir (≤48 h from onset or on admission) reduces mortality and length of stay; short-course post-exposure prophylaxis for exposed patients or staff lowers secondary attack rates. Integrated vaccination efforts for healthcare personnel and high-risk patients reinforce workforce resilience and reduce transmission. Conclusions: A standardized, clinician-led bundle-early molecular testing, do-not-delay antivirals, decisive cohorting and Personal protective equipment (PPE), targeted chemoprophylaxis, vaccination, and disciplined communication- could help curb transmission, protect vulnerable patients and staff, and preserve capacity. Hospitals should codify COVID-era layered controls for seasonal influenza and rehearse unit-level outbreak playbooks to accelerate response and recovery. These recommendations target clinicians and infection-prevention leaders in acute-care hospitals.

Cognition, Cytokines, Blood-Brain Barrier, and Beyond in COVID-19: A Narrative Review.

International journal of molecular sciences, 27(1):.

Numerous studies report cognitive impairment in COVID-19 patients from the acute to post-acute phases, linked to blood inflammation affecting blood-brain barrier (BBB) permeability and causing leakage of glial and neuronal proteins. However, a clear classification of these cognitive deficits and molecular blood events over time is still lacking. This narrative review summarizes the neuropsychological consequences of COVID-19 and evidence of altered cytokines and BBB disruption as potential mediators of cognitive impairment across post-infection phases. Post-COVID-19 cognitive dysfunction appears to follow a temporal course, evolving from acute focal deficits in attention, working memory, and executive function to more persistent multidomain impairments. We reviewed key cytokines released into the blood during COVID-19 infection, including antiviral (IFNγ, CXCL1, CXCL10), inflammatory (IL-1β, IL-2, IL-4, IL-6, IL-7, IL-8, IL-10, GM-CSF, TNFα), and monocyte chemoattractants (MCP1/CCL2, MCP3/CCL7, MIP-1α/CCL3, GM-CSF, G-CSF). This analysis shows that several inflammatory and viral cytokines remain elevated beyond the acute phase and are associated with cognitive deficits, including IL-6, IL-13, IL-8, IL-1β, TNFα, and MCP1 in long-term post-COVID-19 patients. In addition, we examined studies analyzing changes over time in neurovascular unit proteins as biomarkers of BBB disruption, including extracellular matrix proteins (PPIA, MMP-9), astrocytes (S100β, GFAP), and neurons (NFL). These proteins are elevated in acute COVID-19 but generally return to control levels within six months, suggesting BBB restoration. However, in patients followed for over a year, BBB disruption persists only in those with cognitive impairment and is associated with systemic inflammation, with TGFβ as a related biomarker. Although cognitive sequelae can persist for over 12 months after SARS-CoV-2 infection, further studies are needed to investigate long-term neurocognitive outcomes and their link to sustained proinflammatory cytokine elevation and brain impact.

Vascular Complications of Long COVID-From Endothelial Dysfunction to Systemic Thrombosis: A Systematic Review.

International journal of molecular sciences, 27(1):.

Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is associated not only with respiratory illness but also with profound vascular and coagulation disturbances. Long COVID (LC) is characterized by persistent symptoms such as fatigue, dyspnea, cognitive impairment, and palpitations. Mechanistically, SARS-CoV-2 induces direct endothelial injury, promotes a pro-inflammatory cytokine milieu, and activates platelets, leading to immunothrombosis and impaired fibrinolysis. Consequently, patients exhibit microthrombosis, elevated plasma D-dimer, fibrinogen dysregulation, and persistent hypercoagulability. Clinically, this translates into an increased risk of venous thromboembolism, including deep vein thrombosis and pulmonary embolism, as well as arterial thrombotic events such as myocardial infarction and stroke, which may persist months after acute infection. Understanding the interplay between endothelial injury, inflammation, and coagulation is crucial for risk stratification and the development of preventive and therapeutic strategies. We conducted a systematic narrative review of the literature, including human clinical and mechanistic studies identified through PubMed, Scopus and Web of Science up to 30 September 2025. This review synthesizes current evidence on vascular complications in LC, highlighting endothelial dysfunction as a central pathophysiological nexus linking the acute phase of SARS-CoV-2 infection with chronic LC manifestations.

The Central Role of Macrophages in Long COVID Pathophysiology.

International journal of molecular sciences, 27(1):.

This review article attempts to provide a unifying hypothesis to explain the myriad of symptoms and predispositions underlying the development of PASC (Postacute Sequelae of COVID), often referred to as Long COVID. The hypothesis described here proposes that Long COVID is best understood as a disorder of persistent immune dysregulation, with chronic macrophage activation representing the fundamental underlying pathophysiology. Unlike transient post-viral syndromes, Long COVID involves a sustained innate immune response, particularly within monocyte-derived macrophages, driven by persistent spike protein (peripherally in MAIT cells and centrally in Microglial cells), epigenetic imprinting, and gut-related viral reservoirs. These macrophages are not merely activated temporarily but also become epigenetically "trained" into a prolonged inflammatory state, as demonstrated by enduring histone acetylation markers such as H3K27acDNA Reprogramming. It is proposed that recognizing macrophage activation as the central axis of Long COVID pathology offers a framework for personalized risk assessment, targeted intervention, and therapeutic recalibration.

Targeting Host Dependency Factors: A Paradigm Shift in Antiviral Strategy Against RNA Viruses.

International journal of molecular sciences, 27(1):.

RNA viruses, such as SARS-CoV-2 and influenza, pose a persistent threat to global public health. Their high mutation rates undermine the effectiveness of conventional direct-acting antivirals (DAAs) and facilitate drug resistance. As obligate intracellular parasites, RNA viruses rely extensively on host cellular machinery and metabolic pathways throughout their life cycle. This dependency has prompted a strategic shift in antiviral research-from targeting the mutable virus to targeting relatively conserved host dependency factors (HDFs). In this review, we systematically analyze how RNA viruses exploit HDFs at each stage of infection: utilizing host receptors for entry; remodeling endomembrane systems to establish replication organelles; hijacking transcriptional, translational, and metabolic systems for genome replication and protein synthesis; and co-opting trafficking and budding machinery for assembly and egress. By comparing strategies across diverse RNA viruses, we highlight the broad-spectrum potential of HDF-targeting approaches, which offer a higher genetic barrier to resistance, providing a rational framework for developing host-targeting antiviral therapies.

Immune Delay, Beyond Immune Evasion, as a Driver of Pathogen Propagation Competence Through Neutrophil Dysregulation, to be Mitigated by Low-Frequency Electromagnetic Fields (LF-EMF).

International journal of molecular sciences, 27(1):.

This paper proposes that immune delay, beyond immune evasion, is key in the propagation competence of major viral and bacterial infections, and that the dynamics of infection and immune response suggest possibilities for mitigating the ensuing infectious diseases. Recent data show a critical role of neutrophils at various stages of viral and bacterial infections, revealing how early activation of neutrophils could help mitigate infectious diseases. It could prevent the gradual overactivation of subclasses of neutrophils and probably not induce it. In respiratory virus infections, an immune delay of several days allows the development of a high viral load supporting infectivity towards further hosts when a delayed and increased immune response takes place. Virus variants will optimize immune delay towards highest infectivity, supporting pandemic potential. The influenza virus, coronavirus, and several major bacterial infections exhibit such immune delay capability. Recurrent urinary tract infections (rUTI) are common, often associated with the causative uropathogenic E. coli (UPEC) that has this capability, suggesting that immune delay is crucial in the pathogenesis of rUTI and other widespread bacterial infections. Counteracting immune delay, therefore, is a promising approach for mitigating infectious diseases with epidemic and pandemic presence or potential. Previously proven low-frequency electromagnetic field (LF-EMF)-induced neutrophil activation is such an approach.

Single-Use Flexible Bronchoscopy: Advances in Technology and Applications.

Diagnostics (Basel, Switzerland), 16(1):.

With advances in scope and imaging technology, the use of single-use flexible bronchoscopy (SUFB) has broadened beyond intensive care units and operating rooms to bronchoscopy units, with an expanding body of literature suggesting adequate and comparable procedure outcomes, including airway inspection, bronchoalveolar lavage, endobronchial brushing and endobronchial biopsy, in comparison to standard reusable flexible bronchoscopy (RFB). Advantages such as mobility, ease of use and lack of requirement for cleaning staff during the COVID-19 pandemic led to a global increase in usage, with many companies developing SUFB as part of their bronchoscopy portfolio. In parallel, there has been more attention and initiatives to minimise the risk of infection transmission related to bronchoscopy. RFB requires maximum adherence to manufacturer-recommended cleaning protocols. However, evidence of transmissible organisms after cleaning is reported in healthcare settings of all types. After initial benchtop, retrospective and single-arm studies, comparative bronchoscopy studies are identifying that SUFB are as versatile and non-inferior to RFB. However, cost-effectiveness and sustainability factors have to be included in deciding the use of SUFB in routine practice.

Feline Infectious Peritonitis: A Challenging Diagnostic and Therapeutic Labyrinth.

Animals : an open access journal from MDPI, 16(1):.

Feline coronaviruses (FCoVs) are ubiquitous pathogens, exhibiting high prevalence across feline populations worldwide. Although the virulent mutated biotype feline infectious peritonitis virus (FIPV) is observed in only a small percentage of cats, it causes a systemic and often fatal disease. Diagnosis of feline infectious peritonitis (FIP) is challenging due to its non-specific clinical signs and the difficulty in differentiating between the two biotypes, feline enteric coronavirus (FECV) and FPIV. Currently, veterinarians rely on a combination of diagnostic methods, integrating laboratory tests, anamnesis and clinical signs to improve the diagnostic accuracy of FIP. Once considered untreatable, FIP now benefits from recent pharmacological advances that suggest promising therapeutic options, including antiviral drugs and immunomodulatory therapies. Despite these developments, the lack of an effective vaccine and definitive curative treatment highlights the need for continued research. This review provides a comprehensive analysis of the current literature on diagnostic and treatment approaches for FIP. The aim is to improve understanding of the available options and strategies for FIP to mitigate its severe consequences.

Virus-induced endothelial senescence as a cause and driving factor for ME/CFS and long COVID: mediated by a dysfunctional immune system.

Cell death & disease, 17(1):16.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and long COVID are two post-viral diseases, which share many common symptoms and pathophysiological alterations. Yet a mechanistic explanation of disease induction and maintenance is lacking. This hinders the discovery and implementation of biomarkers and treatment options, and ultimately the establishment of effective clinical resolution. Here, we propose that acute viral infection results in (in)direct endothelial dysfunction and senescence, which at the blood-brain barrier, cerebral arteries, gastrointestinal tract, and skeletal muscle can explain symptoms. The endothelial senescence-associated secretory phenotype (SASP) is proinflammatory, pro-oxidative, procoagulant, primed for vasoconstriction, and characterized by impaired regulation of tissue repair, but also leads to dysregulated inflammatory processes. Immune abnormalities in ME/CFS and long COVID can account for the persistence of endothelial senescence long past the acute infection by preventing their clearance, thereby providing a mechanism for the chronic nature of ME/CFS and long COVID. The systemic and tissue-specific effects of endothelial senescence can thus explain the multisystem involvement in and subtypes of ME/CFS and long COVID, including dysregulated blood flow and perfusion deficits. This can occur in all tissues, but especially the brain as evidenced by findings of reduced cerebral blood flow and impaired perfusion of various brain regions, post-exertional malaise (PEM), gastrointestinal disturbances, and fatigue. Paramount to this theory is the affected endothelium, and the bidirectional sustainment of immune abnormalities and endothelial senescence. The recognition of endothelial cell dysfunction and senescence as a core element in the aetiology of both ME/CFS and Long COVID should aid in the establishment of effective biomarkers and treatment regimens.

Health human resources shortages in radiography and sustainable workforce development in Australia.

Radiography (London, England : 1995), 32(2):103319 pii:S1078-8174(25)00463-8 [Epub ahead of print].

OBJECTIVES: Health Human Resources (HHR) are critical for the effective functioning of healthcare systems, yet significant shortages exist, particularly in radiography. The increasing demand for diagnostic radiography services, driven by advancements in medical technology, an aging population, and the prevalence of chronic diseases, exacerbates these shortages. The COVID-19 pandemic further highlighted workforce vulnerabilities, increasing workloads and burnout. This review examines HHR shortages in radiography in Australia and proposes strategies for sustainable workforce development.

KEY FINDINGS: The aging radiography workforce, with a significant portion nearing retirement, intensifies HHR shortages. The pandemic disrupted education and training, delaying the entry of new professionals and increasing turnover intentions among existing staff. The result being delayed imaging services, increased wait times, and potentially compromised patient outcomes. To address these challenges, a multifaceted strategy is proposed. Policy changes and government initiatives, including funding educational programs and recognizing internationally trained radiographers, can provide immediate relief. Expanding enrolment capacities and developing new training programs are essential. Retention strategies, including improving working conditions and career advancement opportunities, are crucial for workforce stability. Promoting advanced practice models can optimize task distribution and better utilize specialized skills. Leveraging technology, such as artificial intelligence and telehealth, can enhance productivity and extend service reach.

CONCLUSION: A comprehensive approach combining policy changes, educational initiatives, retention strategies, technology integration, international recruitment, and awareness campaigns is essential for addressing HHR shortages in radiography. By implementing these strategies, the radiography workforce can be better equipped to meet the growing demands of healthcare, ensuring optimal patient outcomes and the sustainability of health services.

IMPLICATIONS FOR PRACTICE: Strengthening the radiography workforce will ensure timely and effective healthcare delivery, support health interventions, and progress towards universal health coverage and Sustainable Development Goals.

The OAS-RNase L pathway: Insights from experiments of nature.

Science immunology, 11(115):eads9407.

The 2'-5' oligoadenylate synthetases (OASs) are type I interferon-inducible enzymes that, with ribonuclease L (RNase L), have been studied in the context of their coupled action as antiviral effectors. RNase L degrades host and viral ssRNA, affecting diverse cellular processes including translational arrest, interferon response, and apoptosis, all of which are thought to restrict viral replication. Recent studies of recessive inborn errors of human OAS1, OAS2, and RNase L, however, revealed that for SARS-CoV-2 infection, the main protective action of this pathway in natura may be through restricting phagocyte-driven postviral inflammation rather than restricting early viral replication in the respiratory tract. This finding is consistent with the identification of gain-of-function OAS1 mutations in humans with autoinflammation also driven by myeloid cells. Here, we retrace the investigation of the OAS-RNase L pathway, focusing on these recent in natura studies in humans that reposition the pathway as a determinant of the inflammatory response under natural conditions of infection.

Take Fatigue or Fatigues into Account in Physiotherapy Interventions? A Rapid Scoping Review.

Physical therapy research, 28(3):157-173.

Fatigue is one of the most common symptoms encountered in rehabilitation and during physical therapy interventions. Although this phenomenon is known and experienced by everyone, its assessment is not straightforward. The lack of consensus on its definition, complex etiology, and multidimensional nature means that a large number of outcomes exist and continue to be reviewed. However, it seems essential that its assessment be better defined and standardized to understand the effects of physical therapy. To provide an initial exploratory overview, we conducted a rapid scoping review of the various fatigue assessments used in physiotherapy interventions or performed by physical therapists. A total of 139 articles published between 2020 and July 31, 2025 were included and explored. We found 43 different outcomes used across 46 population groups. While the most well-known chronic conditions such as cancer, multiple sclerosis (MS), and coronavirus disease 2019 (COVID-19) are representative, their assessment methods do not appear to be harmonized. These findings from the study support the idea that fatigue remains a complex phenomenon to assess. However, it appears that the lack of justification for the choice of an outcome prevents a better understanding of the reproducible effects on fatigue in physiotherapy interventions.

Patients' experiences of video consultations: A qualitative systematic review.

Digital health, 12:20552076251404513.

INTRODUCTION: Video consultation (VC) became vital for improving healthcare access during COVID-19 pandemic and remains so. Despite evidence of effectiveness, concerns including technology literacy and inconsistencies in experience highlight the need for larger, patient-focused studies. While patients appreciate the convenience of VC, challenges during complex issues and patients' preferences for in-person care persists. Synthesising qualitative studies offers insights into the fragmented understanding of patient experiences with VC. This review explores adult patients' experiences of VC.

METHODS: A systematic literature search was conducted for studies published between 2011 and 2024 and reported according to the PRISMA statement. Study quality was assessed using the CASP checklist, and data were analysed through thematic synthesis. Confidence in the findings was evaluated using GRADE-CERQual.

RESULTS: In total, 3203 unique studies were retrieved; 13 were included in the final synthesis, resulting in four main themes: (1) suitable for less complex issues when technical problems can be solved; (2) feeling secure, relaxed, and having mutual focus in an equitable partnership; (3) limitations regarding personal needs and practical help; and (4) increased vulnerability and lack of emotional feedback.

CONCLUSION: VC is experienced as ideal for managing less complex issues but is challenging for emotional topics due to technical concerns. It empowers patients by providing a neutral place for focused conversations but can create vulnerability and distance that can challenge the patient-professional relationship. Success requires technological adaptation, sufficient time during VC, and emotional support. VC should complement - not replace - traditional care, with its use determined in dialogue with patients.

Multiscale imaging of RNA virus: bridging structural mapping and functional insights.

Trends in microbiology pii:S0966-842X(25)00365-8 [Epub ahead of print].

RNA viruses, exemplified by the COVID-19 pandemic, pose a significant threat to global health. Their rapid mutation and host adaptability highlight the need for advanced tools for efficient viral studies and timely countermeasure development. Imaging technologies, such as cryo-electron microscopy and super-resolution microscopy, have been pivotal in advancing our understanding of viral structures, infection mechanisms, and virus-host interactions. However, each technique has limitations in the field of view or resolution. Recent advancements have focused on developing integrated multiscale imaging to better understand RNA virus pathogenesis. In this review, we examine recent progress in RNA virus imaging across molecular, cellular, and tissue scales, including cryo-electron tomography and correlative multiscale imaging, which link structural mapping with functional insights.

Emerging viroporins, RBP dynamics, and skeletal remodeling: Targeting liquid-liquid phase separation for dual antiviral and bone-protective therapies.

Molecular aspects of medicine, 107:101445.

Emerging and re-emerging viral pathogens, particularly Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), Zika virus (ZIKV), and Chikungunya virus (CHIKV), are currently recognized as a significant global public health issue, commonly leading to devastating persistent complications including inflammatory bone disorders and long-lasting arthralgia. Although systemic cytokine storm has been reported as a significant factor, the particular intracellular processes through which these viruses affect bone homeostasis are still poorly understood. Recent studies underscore Liquid-Liquid Phase Separation (LLPS) and RNA-Binding Proteins (RBPs) as significant regulatory mechanisms manipulated by these viruses. Particularly, the SARS-CoV-2 Nucleocapsid protein exploits its intrinsically disordered regions to promote LLPS, facilitating viral assembly by the active inhibition of a key host anti-viral mechanism, known as host Stress Granules. Studies suggest that this biophysical interaction can affect the stability of the HuR RBD, impairing the nuclear β-catenin localization and then Wnt-mediated osteogenesis. Despite increasing recognition of post-viral musculoskeletal complications, the mechanistic links between viral persistence, host RBP dysfunction, and impaired bone remodeling remain poorly defined. This review incorporates viral LLPS, stress granule impairment, and osteogenic signaling into a unified 'Two-Hit' pathogenic framework. It also addresses key knowledge gaps, including the lack of longitudinal clinical validation and in vivo evidence associating LLPS impairment to skeletal disorders. Interestingly, this framework represents translational opportunities for dual-action therapeutic strategies that simultaneously impair viral condensates and recover host RBP-associated osteogenic signaling. Targeting the virus-host phase interface can introduce a potential approach not only for antiviral therapies but also for inhibiting post-viral musculoskeletal complications.

Dual-function cytokines as modulators of autophagy: reprogramming inflammatory resolution in severe COVID-19.

Inflammation research : official journal of the European Histamine Research Society ... [et al.], 75(1):11.

BACKGROUND: Acute respiratory distress syndrome (ARDS) and systemic immune-mediated damage are two of the severe COVID-19 outcomes that are primarily caused by cytokine storms triggered by dysregulated immune responses. The limited benefits of current immunosuppressive treatments highlight the need for mechanistic understanding to direct focused interventions.

OBJECTIVE: The dual functions of cytokines in controlling autophagy during SARS-CoV-2 infection are examined in this review, along with the potential for autophagy modulation to limit hyperinflammation and restore immune homeostasis.

KEY FINDINGS: Emerging evidence suggests that autophagy critically modulates the balance between pro- and anti-inflammatory cytokines in COVID-19. Through anti-inflammatory feedback mechanisms, cytokines contribute to resolution while promoting inflammation in the early stages. The IRE1α-XBP1 axis is activated by SARS-CoV-2-induced endoplasmic reticulum stress, which increases cytokine production and modifies autophagic flux. Concurrently, extracellular vesicles containing cytokines, damage-associated molecular patterns, and viral components are released as secretory autophagy reroutes cytoplasmic cargo toward multivesicular bodies and amphisomes, increasing paracrine immune activation. Suppressed degradative autophagy and increased secretory autophagy-mediated inflammatory signaling are the hallmarks of this pathological state.

CONCLUSIONS: In severe COVID-19, targeted autophagy restoration is a promising therapeutic approach to restore immune responses, reduce excessive inflammation, and encourage the resolution of cytokine storms. Restoring immune homeostasis through more targeted immunointerventions may be made possible by modifying autophagy pathways.

Coronavirus genome packaging and nucleocapsid assembly.

Journal of virology [Epub ahead of print].

Coronaviruses are a family of positive-strand RNA viruses that exhibit highly selective packaging of their genomic RNA (gRNA) into assembled virions, despite the presence of a large excess of subgenomic viral RNA species and host RNA in infected cells. While this high selectivity is critical to evading host innate immune responses, surprisingly, it is not essential for virion assembly. This review focuses on four main topics: (i) coronavirus genome packaging signals (PSs)-how they are found and the function they serve; (ii) the viral components that recognize the PS in order to bring about selective gRNA packaging; (iii) coronavirus nucleocapsid structure and assembly; and (iv) the relationship between nucleocapsid protein phosphorylation and nucleocapsid assembly versus RNA synthesis. Current understanding of these areas has benefited immensely from advances made by recent studies, most of which were performed in response to the emergence of the coronavirus responsible for the COVID-19 pandemic. Throughout this review, emphasis is placed on the counterintuitive distinction between coronavirus selective gRNA packaging and nucleocapsid assembly.

Biosimilars in Gynecologic Cancers: Basic Principles and New Horizons.

Frontiers in bioscience (Elite edition), 17(4):33415.

Biological therapies have transformed cancer treatment by targeting the molecular mechanisms involved in carcinogenesis. However, higher costs, limited accessibility, and supply chain disruptions-such as those caused by COVID-19 in recent years-underscore the need for cost-effective alternatives. Biosimilars, which are drugs that are highly similar to their reference biologics in terms of safety, efficacy, and quality, offer a viable solution (as these demonstrate clinically meaningful outcomes). This review article examines the role of biosimilars, mainly in gynecological cancers. The primary focus of this article is to compare the efficacy, safety, and cost-effectiveness of biosimilars, as well as to explore the barriers that restrict their widespread adoption. A comprehensive literature review was conducted, analyzing various studies, regulatory guidelines, and the latest data on biosimilars for the treatment of gynecological cancers. Pivotal trials, such as the GOG-0218, ICON7, and RUBY, were reviewed to assess the efficacy, safety, and cost-effectiveness of these biosimilars. This review highlights key oncologic therapies, including bevacizumab, trastuzumab, pembrolizumab, and their biosimilars, mainly for gynecological cancers. Additionally, this review considers the challenges of immunogenicity, interchangeability, and clinician awareness. After reviewing the latest peer-reviewed literature and related online materials, we found that biosimilars demonstrate comparable efficacy and safety to their reference biologics while also being more cost-effective. Recent clinical trials support the role of biosimilars in limiting the progression of disease and improving overall survival while reducing the financial burden of cancer treatments.

Herpes Zoster (HZ) Over the Past 10 Years: A Systematic Review on Trends, Triggers, and Post-COVID-19 Impact.

Cureus, 17(12):e98556.

Herpes zoster (HZ) is a reactivation of varicella-zoster virus (VZV), which has been traditionally associated with aging and immunosuppression. However, new data indicate that the coronavirus disease 2019 (COVID-19) pandemic has changed HZ epidemiology, with a higher incidence of HZ in post-COVID-19 patients and vaccinated subjects. This systematic review assesses the trends and triggers of HZ as well as the impact after the pandemic, focusing on the changes in the incidence rate among adult and pediatric patients during the last 10 years. All studies published between the years of 2014 and 2024 were accrued, based on a systematic review conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant articles were identified from searches of databases and other sources. Eligibility criteria of studies were applied, and qualitative and quantitative syntheses of studies were performed. A total of 11 studies were included in the review, which examined the association between COVID-19, vaccination, and HZ risk. Several studies suggested that psychological stress and immune dysfunction could be risk factors for HZ incidence. HZ cases after COVID-19 vaccination have been reported, although causation is not established. Based on countries in which COVID-19 was diagnosed, hospitalizations are estimated at 14.4 per 100,000 inhabitants (0.6 to 32.9 per 100,000), and mortality was 1.3 per 100,000, points in this IR Batch (assuming that these are of all diagnosed cases). The risk of HZ reactivation may be increased following COVID-19 infection and vaccination. Higher hospitalization rates with higher mortality risks and neurological consequences were also observed in some populations. Strengthening HZ vaccination programs and studying post-COVID-19 immune responses further can be essential for reducing long-term health risks.

MIS-C: Diagnosis, Management, and Outcomes.

Open forum infectious diseases, 13(1):ofaf762.

Multisystem inflammatory syndrome in children (MIS-C) is an emergent postinfectious hyperinflammatory disorder predominantly affecting the pediatric population following COVID-19 infection. Clinically, it is characterized by persistent fever, shock, multiorgan involvement, and potentially severe cardiovascular involvement. This comprehensive review synthesizes current evidence on the epidemiology, pathophysiology, clinical presentation, diagnostic criteria, with particular emphasis on the management of MIS-C. We also stress on the importance of distinguishing MIS-C from phenotypically similar entities. Acute-phase management centers on supportive care, hemodynamic stabilization, and targeted immunomodulation, with intravenous immunoglobulin, corticosteroids, and biologic forming the therapeutic cornerstone. Thromboprophylaxis is frequently warranted due to the elevated thromboembolic risk, and long-term follow-up is essential to monitor for cardiac, gastrointestinal, and neurologic complications. Additional considerations include postrecovery vaccination protocols and the use of extracorporeal membrane oxygenation in cases of refractory cardiorespiratory failure. Despite advancements in clinical outcomes, diagnostic ambiguity and heterogeneous management guidelines continue to pose significant challenges.

Neuro-vestibular rehab: new developments.

Current opinion in neurology, 39(1):83-87.

PURPOSE OF REVIEW: This review highlights recent advances in neuro-vestibular rehabilitation, with emphasis on vestibular adaptation and emerging mobile technologies. It summarizes developments in promoting vestibular plasticity and discusses novel tools such as virtual reality, wearable sensors, and telehealth platforms that enhance access, engagement, and outcomes. The scope is broad, focusing on general principles rather than specific populations.

RECENT FINDINGS: New methods to enhance vestibulo-ocular reflex (VOR) adaptation include incremental adaptation devices and gamified exercises. Inducing VOR gain-down adaptation temporarily increases postural sway, which normalizes via sensory reweighting, demonstrating central compensation. Portable tools like StableEyes show promise in boosting VOR gain with brief sessions. Concurrently, technology-driven approaches are gaining traction. Gamified mobile applications and wearable sensors allow home-based rehabilitation with remote supervision and monitoring, showing promising results in conditions like multiple sclerosis. Virtual reality interventions and telehealth models accelerated during the COVID-19 era, expanding therapy delivery to underserved populations. Adjunctive methods such as vibrotactile feedback and galvanic vestibular stimulation are emerging as complementary therapies.

SUMMARY: Recent developments are advancing vestibular rehabilitation by refining adaptive training techniques and leveraging digital tools to overcome barriers in access and adherence. These innovations point to a more personalized, technology-enabled approach to optimizing neuro-vestibular recovery.

Osmotic nephropathy as a potentially underrecognized cause of acute kidney injury during SGLT2 inhibitor therapy: a case report and literature review.

CEN case reports, 15(1):16.

In recent years, sodium-glucose cotransporter 2 (SGLT2) inhibitors have become essential therapeutic agents in the management of chronic kidney disease (CKD), owing to their established renoprotective effects. Although acute kidney injury (AKI) may occasionally occur during SGLT2 inhibitor therapy, its pathological features remain incompletely understood. Here, we report a case of AKI caused by osmotic nephropathy in a patient with underlying CKD following the initiation of an SGLT2 inhibitor. We also review previously reported cases of SGLT2 inhibitor-associated osmotic nephropathy. A 71-year-old man with type 2 diabetes and CKD developed oliguric AKI, with his serum creatinine level increasing from 2.0 to 8.3 mg/dL, one month after initiating dapagliflozin. During this period, he experienced transient appetite loss associated with a COVID-19 infection. Despite initial management for presumed prerenal AKI, his renal function did not improve with intravenous fluid therapy, and he required hemodialysis. Kidney biopsy revealed characteristic features of osmotic nephropathy, including numerous isometric vacuoles within the epithelial cells of proximal tubules with preserved brush borders. His renal function began to improve approximately two weeks after discontinuation of the SGLT2 inhibitor, and eventually returned to baseline. This case and literature review highlight the potential for osmotic nephropathy as a rare but reversible complication of SGLT2 inhibitor therapy, which may be triggered by volume depletion, particularly in diabetic patients with pre-existing renal dysfunction. Recognition of this underdiagnosed entity is crucial for timely diagnosis and appropriate management.

Decoding emerging viral sepsis: Molecular crosstalk, dysregulation, and precision strategies.

Molecular aspects of medicine, 107:101442.

Emerging and re-emerging viral pathogens pose a major challenge to global public health systems. One of the most significant complications associated with these viruses is viral sepsis, a severe condition characterized by organ dysfunction resulting from an unregulated host response to a viral infection. The present review comprehensively describes the molecular mechanisms underlying viral sepsis induced by emerging and re-emerging viral pathogens, such as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), influenza virus, dengue virus (DENV), Ebola virus (EBOV), and human immunodeficiency virus (HIV). It discusses the complex molecular interactions between particular viral factors and host cellular pathways, highlighting significant dysregulations in various immune responses, metabolic reprogramming, and endothelial integrity that induce sepsis development. Furthermore, this review thoroughly addresses nascent precision strategies, including advanced diagnostics, targeted therapeutics, and immunomodulatory interventions, carefully tailored to distinct viral etiologies and host endotypes. By shedding light on the intricate molecular landscape of viral sepsis, this review aims to provide a robust framework for future mechanistic research and accelerate the development of effective, personalized interventions to combat this challenging complication.

Disease-associated adipose browning: current evidence and perspectives.

Adipocyte, 15(1):2610540.

Brown and beige adipose tissue represent evolutionary adaptations in mammals, functioning as specialized thermogenic organs to maintain body temperature. Over the past two decades, researches have demonstrated that white adipose tissue (WAT) browning is an effective strategy to enhance energy expenditure. However, a growing body of evidence indicates that the browning process frequently occurs in a variety of chronic disease states, though its pathophysiological significance remains unclear. This review summarized evidence of pathological browning observed in human diseases and animal models, including breast cancer, colorectal cancer (CRC), clear cell renal cell carcinoma (ccRCC), kidney health, burn injury, atherosclerotic, SARS-CoV-2 and sepsis. Despite distinct pathological contexts, adipose tissue browning is consistently observed. This suggests that browning may not simply serve its classical metabolically protective role, but instead reflect an atypical response to pathological stress. It is currently unclear whether this is a compensatory mechanism by the organism in a diseased state or merely a byproduct of the disease process. Whether this response is adaptive or a cause of disease progression remains unresolved. Future research should therefore focus on identifying the triggers and functional outcomes of pathological browning to better understand adipocyte plasticity and its role in disease progression.

Understanding the needs and key determinants of maternal, newborn, and child health among migrants in transit: a scoping review.

Global health action, 19(1):2607905.

The global surge in migration has exposed pregnant women and children in transit to heightened risk of maternal and child health (MCH) challenges, driven by systemic barriers and unstable conditions. Evidence on how these transitory factors influence MCH remains limited. This scoping review examined the health needs and key determinants affecting migrant populations in transit, specifically pregnant women and children travelling from their countries of origin to their intended destination countries, with the aim of identifying major barriers and proposing strategies for improved health outcomes. We screened 1202 sources of evidence using five databases (PubMed, Scopus, Europe PMC, CINAHL, and Medline) as well as grey literature. Seven studies met the inclusion criteria. Data were drawn from peer-reviewed literature, charted using a standardized framework, and analysed thematically. Key barriers included financial constraints, language obstacles, and limited access to healthcare services. Although humanitarian organizations offered some support, significant unmet needs remain, including exposure to transactional sex, absence of respectful maternity care, and restricted access to essential health services. These challenges are exacerbated in conflict and crisis settings. The review underscores the importance of addressing key determinants, including location, language, financial capacity, and community support, to improve health outcomes for pregnant women and children under five on the move. This review recommends strengthening community mobilization, leveraging technology, and ensuring equitable access irrespective of users' cultural or financial constraints.

COVID vaccination and post-infection cancer signals: Evaluating patterns and potential biological mechanisms.

Oncotarget, 17:1-29 pii:28824.

A growing number of peer-reviewed publications have reported diverse cancer types appearing in temporal association with COVID-19 vaccination or infection. To characterize the nature and scope of these reports, a systematic literature search from January 2020 to October 2025 was conducted based on specified eligibility criteria. A total of 69 publications met inclusion criteria: 66 article-level reports describing 333 patients across 27 countries, 2 retrospective population-level investigations (Italy: ~300,000 cohort, and Korea: ~8.4 million cohort) quantified cancer incidence and mortality trends among vaccinated populations, and one longitudinal analysis of ~1.3 million US miliary service members spanning the pre-pandemic through post-pandemic periods. Most of the studies documented hematologic malignancies (non-Hodgkin's lymphomas, cutaneous lymphomas, leukemias), solid tumors (breast, lung, melanoma, sarcoma, pancreatic cancer, and glioblastoma), and virus-associated cancers (Kaposi and Merkel cell carcinoma). Across reports, several recurrent themes emerged: (1) unusually rapid progression, recurrence, or reactivation of preexisting indolent or controlled disease, (2) atypical or localized histopathologic findings, including involvement of vaccine injection sites or regional lymph nodes, and (3) proposed immunologic links between acute infection or vaccination and tumor dormancy, immune escape, or microenvironmental shifts. The predominance of case-level observations and early population-level data demonstrates an early phase of potential safety-signal detection. These findings underscore the need for rigorous epidemiologic, longitudinal, clinical, histopathological, forensic, and mechanistic studies to assess whether and under what conditions COVID-19 vaccination or infection may be linked with cancer.

Transforming Emergency Care Through Telemedicine: A Narrative Review.

Cureus, 17(12):e98481.

Telemedicine has fleetly evolved from a niche result to a central pillar in modern emergency and critical care systems. This narrative review delves into the multifaceted role of telemedicine in emergency settings, tracing its historical development, present applications, and future possibilities. It examines how telemedicine islands geographical and infrastructural gaps, particularly in underserved communities, by enabling timely access to specialist care similar to telestroke services and remote ferocious care. Substantiation highlights advancements in clinical outcomes, functional effectiveness, and patient satisfaction, with global case studies demonstrating successful perpetration across both high- and low-resource settings. Despite these advances, challenges persist. Technological restrictions, regulatory barriers, digital knowledge gaps, and unlikeness in assent continue to hamper wide relinquishment. This review discusses these obstacles and underscores the significance of strategic investment, cross-sector collaboration, and policy reform. Arising inventions, including artificial intelligence, wearable devices, and scalable telehealth platforms, signal promising directions for perfecting reach and adaptability in emergency systems. Additionally, this paper identifies crucial areas for unborn research, including long-term outgrowth assessment and telemedicine's part in disaster and pandemic response. By synthesizing current substantiation and practical perceptivity, this review aims to inform clinicians, health system leaders, and policymakers about the transformative eventuality and ongoing challenges of telemedicine in emergency care. Eventually, it calls for sustained invention, equity-concentrated perpetration, and cooperative sweats to completely realize telemedicine's pledge in erecting a more accessible, responsive, and flexible emergency care geography.

Ocular Lesions Related to COVID-19 and Its Vaccines.

Journal of ophthalmology, 2025:7078264.

OBJECTIVE: To review COVID-19 infection and COVID-19 vaccine-related ocular lesions.

METHODS: We carried out a systematic search in PubMed, Web of Science, Embase, and the Cochrane Library on COVID-19 and ophthalmology and reviewed the incidence, specific manifestations, and risk factors for COVID-19-related eye diseases and the relationship between the detection of COVID-19 in the conjunctiva and tears and eye involvement.

RESULTS: Conjunctivitis was the most common ocular lesion caused by 2019-nCoV infection, followed by uveitis and retinopathy. Conjunctivitis can be the first manifestation of COVID-19 infection and may be clinically related to the severity of pneumonia caused by COVID-19. In particular, conjunctivitis that occurs after pneumonia suggests that the patient has severe systemic disease. COVID-19 infection can cause uveitis, but the infection rate of COVID-19 in patients with uveitis is similar to that of the general population. Patients with uveitis need to reduce the dosage of systemic hormones and discontinue biological agents after being infected with COVID-19. Retinopathy caused by COVID-19 infection is mainly manifested as retinal microvascular disease, and the prognosis is good. SARS-CoV-2 detection in the conjunctiva and tears has high sensitivity and is of great value for disease diagnosis. Eye lesions caused by the COVID-19 vaccine, similar to other vaccines, have a low incidence and a good prognosis.

CONCLUSION: COVID-19-related ocular lesions are mainly manifested as conjunctivitis, uveitis, and retinal microvascular changes. These diseases are somewhat self-limiting and have a good prognosis.

Effects of Hypoglycemic Agents on Pulmonary Diseases: A Comprehensive Narrative Review.

Journal of inflammation research, 18:18053-18078.

Beyond glycemic control, hypoglycemic agents exhibit multifaceted effects that may influence pulmonary health in patients with diabetes mellitus. This narrative review synthesizes available evidence from preclinical and clinical studies on the impact of major hypoglycemic drug classes-including biguanides, sulfonylureas, thiazolidinediones, α-glucosidase inhibitors, DPP-4 inhibitors, SGLT-2 inhibitors, GLP-1 receptor agonists, and insulin-on pulmonary diseases. Evidence suggests that these agents exert class-specific, and often conflicting, effects: preclinical studies support their protective potential in acute lung injury, while clinical data indicate variable efficacy in asthma, COPD, and respiratory infections including COVID-19. Conversely, some agents may be associated with increased risks of lung cancer or COPD exacerbations, underscoring the need for context-specific prescribing. Mechanistic insights from animal models primarily involve modulation of inflammatory, oxidative, and immune pathways. This narrative review aims to provide a clinical framework for personalizing hypoglycemic therapy in patients with comorbid pulmonary conditions, while underscoring the need for well-designed prospective studies to resolve existing controversies.

Overview of dendrimers as promising drug delivery systems with insight into anticancer and anti-microbial applications.

International journal of pharmaceutics: X, 10:100390.

Dendrimers are tree-like polymeric molecules that have three main compartments: the core, branching units, and functional end groups. They are nanosized and monodispersed, with an almost spherical shape. For the past few decades, dendrimers have been evaluated in numerous studies as a promising category of candidates for gene delivery and diagnostic applications. Nowadays, some advanced dendrimers are considered promising anticancer delivery systems due to the vast types and applicable modifications. They also showed their effectiveness as antibacterial and antiviral agents. Smart dendrimers with pH-, redox-, or directly tumor microenvironment-responsive properties are investigated. pH-sensitive dendrimers enhance drug release in the tumor's acidic environment and inhibit release at physiological pH, thereby increasing the hemocompatibility of these chemical agents. Dendrimers have been examined for years to prevent sexually transmitted diseases, such as HIV, HPV, HSV, etc. In this regard, some studies yielded encouraging results and opened new avenues. Following the onset of the COVID-19 pandemic, researchers have shifted their focus toward seeking remedies to prevent and treat this viral disease. Dendrimers have already demonstrated favorable efficacy in protection against COVID-19 and other respiratory viral diseases. Furthermore, they may mitigate the neuroinflammatory manifestations of COVID-19 in individuals experiencing a critical disease state.
