Preprocedural testing for severe acute respiratory coronavirus virus 2 (SARS-CoV-2) is frequently used to reduce perioperative morbidity and mortality during the pandemic. Such testing is resource intensive, and the relative benefits depend on local epidemiology. We propose a threshold of 20 per 100,000 unlinked cases to activate such testing to optimize the yield and positive predictive value.

Aberrant immune responses to viral pathogens contribute to pathogenesis, but our understanding of pathological immune responses caused by viruses within the human virome, especially at a population scale, remains limited. We analyzed whole-genome sequencing datasets of 6,321 Japanese individuals, including patients with autoimmune diseases (psoriasis vulgaris, rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), pulmonary alveolar proteinosis (PAP) or multiple sclerosis) and coronavirus disease 2019 (COVID-19), or healthy controls. We systematically quantified two constituents of the blood DNA virome, endogenous HHV-6 (eHHV-6) and anellovirus.

Online meetings have become increasingly prevalent, especially during the coronavirus disease 2019 pandemic. Although they offer convenience and effectiveness in various contexts, there is a pertinent question about whether they truly replicate the richness of in-person communication. This study delves into the distinctions between online and face-to-face interactions, with a particular focus on the synchronization of brain activity.

Lessons from COVID-19 in Taiwan's long-term care facilities: A narrative review.

J Formos Med Assoc

January 2025

Department of Internal Medicine, National Taiwan University Hospital, No.7, Chung Shan S. Rd.(Zhongshan S. Rd.), Zhongzheng Dist., Taipei City, 100225, Taiwan, ROC; College of Medicine, National Taiwan University, No.1 Jen Ai road section 1, Taipei 100, Taiwan, ROC. Electronic address:

The coronavirus Disease 2019 (COVID-19) pandemic has disproportionately impacted long-term care facilities (LTCFs), revealing vulnerabilities due to residents' advanced age, comorbidities, and facility infrastructures. In Taiwan, the Central Epidemic Control Center implemented a range of strategies to protect LTCF residents. These included early containment measures to allow time for preparing pharmaceutical intervention, the establishment of infection prevention and control guidelines, the implementation of comprehensive screening and testing protocols, the prioritization of vaccination for both residents and staff, and the expansion of the national stockpile of oral antiviral agents.

Behind the scenes of EQA - characteristics, capabilities, benefits and assets of external quality assessment (EQA).

Clin Chem Lab Med

Canadian Microbiology Proficiency Testing Program (CMPT), Department of Pathology and Laboratory Medicine, University of British Columbia, Vancouver, Canada.

External quality assessment (EQA) enhances patient safety through the evaluation of the quality of laboratory-based and point of care testing. Regulatory agencies and accreditation organizations utilize the results and the laboratory's response to them as part of assessing the laboratory's fitness to practice. In addition, where EQA samples are commutable and the assigned value has been determined using reference measurement procedures (RMPs), EQA data contributes to the verification of metrological traceability of assays as part of the post-market surveillance of diagnostic (IVD) medical devices (IVD-MDs).

Research review and transcriptomic insights into Benzalkonium chloride inhalation and disease association.

Ecotoxicol Environ Saf

January 2025

College of Pharmacy, Korea University, Sejong 30019, South Korea. Electronic address:

The widespread use of disinfectants, particularly during the coronavirus disease (COVID-19) pandemic, has significantly increased human exposure to biocides, raising concerns about their potential health risks, especially when inhaled. Benzalkonium chloride (BKC), a quaternary ammonium compound commonly used as a disinfectant and preservative, is a notable example because it is frequently used in household products and medical settings. Despite its broad usage, limited research has been conducted on the respiratory and systemic toxicities of BKC.
