    The extensive sequence data generated from SARS-CoV-2 during the 2020 pandemic has facilitated the study of viral genome evolution over a brief period of time. This has highlighted instances of directional mutation pressures exerted on the SARS-CoV-2 genome from host antiviral defense systems. In this brief review we describe three such human defense mechanisms, the apolipoprotein B mRNA editing catalytic polypeptide-like proteins (APOBEC), adenosine deaminase acting on RNA proteins (ADAR), and reactive oxygen species (ROS), and discuss their potential implications on SARS-CoV-2 evolution.

    Bacillus Calmette–Guérin (BCG) vaccination has been reported to decrease susceptibility to respiratory tract infections, an effect proposed to be mediated by the general long-term boosting of innate immune mechanisms, also termed trained immunity. Here, we discuss the non-specific beneficial effects of BCG against viral infections and whether this vaccine may afford protection to COVID-19. Could the BCG vaccine be used to bridge the gap until a specific COVID-19 vaccine is developed? Luke O’Neill and Mihai Netea discuss the science behind this approach.

    The 22nd annual Bioinformatics Open Source Conference (BOSC 2021, open-bio.org/events/bosc-2021/) was held online as a track of the 2021 Intelligent Systems for Molecular Biology / European Conference on Computational Biology (ISMB/ECCB) conference. Launched in 2000 and held every year since, BOSC is the premier meeting covering topics related to open source software and open science in bioinformatics. In 2020, BOSC partnered with the Galaxy Community Conference to form the Bioinformatics Community Conference (BCC2020); that was the first BOSC to be held online. This year, BOSC returned to its roots as part of ISMB/ECCB 2021. As in 2020, the Covid-19 pandemic made it impossible to hold the conference in person, so ISMB/ECCB 2021 took place as an online meeting attended by over 2000 people from 79 countries. Nearly 200 people participated in BOSC sessions, which included 27 talks reviewed and selected from submitted abstracts, and three invited keynote talks representing a range of global perspectives on the role of open science and open source in driving research and inclusivity in the biosciences, one of which was presented in French with English subtitles.

    Abstract Background During the current COVID-19 health crisis virtual geriatric clinics have become increasingly utilised to complete outpatient consultations, although concerns exist about feasibility of such virtual consultations for older people. The aim of this rapid review is to describe the satisfaction, clinic productivity, clinical benefit, and costs associated with the virtual geriatric clinic model of care. Methods A rapid review of PubMed, MEDLINE and CINAHL databases was conducted up to April 2020. Two independent reviewers extracted the information. Four subdomains were focused on: satisfaction with the virtual geriatric clinic, clinic productivity, clinical benefit to patients, costs and any challenges associated with the virtual clinic process. Results Nine studies with 975 patients met our inclusion criteria. All were observational studies. Seven studies reported patients were satisfied with the virtual geriatric clinic model of care. Productivity outcomes included reports of cost-effectiveness, savings on transport, and improved waiting list metrics. Clinical benefits included successful polypharmacy reviews, and reductions in acute hospitalisation rates. Varying challenges were reported for both clinicians and patients in eight of the nine studies. Hearing impairments and difficulty with technology added to anxieties experienced by patients. Physicians missed the added value of a thorough physical examination and had concerns about confidentiality. Conclusion Virtual geriatric clinics demonstrate evidence of productivity, benefit to patients, cost effectiveness and patient satisfaction with the treatment provided. In the current suboptimal pandemic climate, virtual geriatric clinics may allow Geriatricians to continue to provide an outpatient service, despite the encountered inherent challenges.

    The entry of falsified and substandard medicines into the legitimate pharmaceutical supply chain has negative impacts on healthcare systems, patient safety, and patient access to medicine. The COVID-19 pandemic has highlighted the importance of access to safe medicine through legitimate pharmaceutical supply chains and the willingness of criminals to target medical products such as PPE (personal protective equipment) and COVID-19 treatments. In this article, we analyse data from the United Kingdom (UK) national medicine alert and recall database to identify and understand recent cases of substandard and falsified medicine in the UK’s healthcare systems. Using the UK as a case study, we describe that national drug alert and recall data are useful in their current form to record and understand cases of substandard and falsified medicines in the supply chain. However, if regulatory agencies published further data, these drug recall databases may be useful to support longitudinal and international comparative medicine quality studies. We suggest that regulatory agencies publish the number of affected medicine packs in each recalled batch, as part of the recall process. This will help policy makers, practitioners, and researchers to better understand, monitor and compare the quality of medicines within legitimate supply chains.

    This research report looks at leadership and wellbeing in Primary Schools two months after the COVID-19 school closures, in total 939 leaders completed the survey. It follows a previous report on practice in Primary Schools two weeks after school closures (Burke and Dempsey, 2020). It reports on the changes in communication, concerns and wellbeing from week two to month two after the COVID-19 school closure; the wellbeing of school leaders in the middle of the COVID-19 school closure; and, investigates the intricacies in wellbeing between teaching and administrative principals, given that their daily duties differ significantly. Quantitative data was analysed using SPSS, and qualitative data was analysed using MAXQDA. It found that principals are adapting to the impact of the pandemic, both professionally and personally, however there have been significant challenges noted. It was noted that social wellbeing is the biggest challenge for principals, however seven out of 10 principals have taken specific actions to address this challenge during the lockdown. Lack of time was an issue for those principals who have not taken positive action regarding their wellbeing, with some fulfilling multiple professional and personal roles. While there have been challenges associated with the adaptation and implementation of new online practices, and some schools lack technology, there has been a positive move to online learning.

    Abstract Background Coronavirus disease 2019 (COVID-19) has evolved as a pandemic of unimaginable magnitude. The health care system is facing a tremendous challenge to provide ethical and quality care. The transformation of the patient-based care to population-based care during the COVID-19 pandemic has raised ethical dilemma among urologists. Our objective is to explore the consensus in modified standard urology care, that can be adopted and applied during COVID-19 and similar pandemic. Methods We adopted an exploratory study design using secondary data. The data were extracted from a web-based medical library using keywords “COVID-19,” “severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2),” and “urology.” We identify and extrapolate (screening, eligibility, and inclusion) the data using PRISMA protocol, and summarize pandemic standard urology care under four main themes: (1) general urology care, (2) choice of surgical modality, (3) triage, and (4) urology training. Result We identified 63 academic papers related to our research question. The majority are expert opinions and perspectives on urology care. The common consensus is triage-based urology care and surgeries. Life or organ threatening conditions need immediate attention. Universal protective measures (personal protective equipment, safe operative environment) and protocol-based patient care are necessary to prevent and control SARS-CoV-2 infection. Conservation of the resources and its rational distribution provide an ethical basis for population-based health care during a pandemic. Informed decision making serves best to patients, families, and society during the public health crisis. Conclusion COVID-19 pandemic tends to transform standard urology practice into crisis standard population-based care. The consensus in crisis is drawn from evolving pieces of medical evidence and public health ethics. The provision of urology care during a pandemic is based on the availability of resources; severity of the disease, consequences of deferment of service, and dynamics of the pandemic.

    Abstract Background Best practice for prevention, diagnosis, and management of venous thromboembolism (VTE) in patients with coronavirus disease 2019 (COVID‐19) is unknown due to limited published data in this population. Objectives We aimed to assess current global practice and experience in management of COVID‐19–associated coagulopathy to identify information to guide prospective and randomized studies. Methods Physicians were queried about their current approach to prophylaxis, diagnosis, and treatment of VTE in patients with COVID‐19 using an online survey tool distributed through multiple international organizations between April 10 and 14, 2020. Results Five hundred fifteen physicians from 41 countries responded. The majority of respondents (78%) recommended prophylactic anticoagulation for all hospitalized patients with COVID‐19, with most recommending use of low‐molecular‐weight heparin or unfractionated heparin. Significant practice variation was found regarding the need for dose escalation of anticoagulation outside the setting of confirmed or suspected VTE. Respondents reported the use of bedside testing when unable to perform standard diagnostic imaging for diagnosis of VTE. Two hundred ninety‐one respondents reported observing thrombotic complications in their patients, with 64% noting that the complication was pulmonary embolism. Of the 44% of respondents who estimated incidence of thrombosis in patients with COVID‐19 in their hospital, estimates ranged widely from 1% to 50%. One hundred seventy‐four respondents noted bleeding complications (34% minor bleeding, 14% clinically relevant nonmajor bleeding, and 12% major bleeding). Conclusion Well‐designed epidemiologic studies are urgently needed to understand the incidence and risk factors of VTE and bleeding complications in patients with COVID‐19. Randomized clinical trials addressing use of anticoagulation are also needed.

    Background Clinicians working in mental health (MH) services seem to be at increased risk of burnout. This study aimed to investigate the stress and burnout levels of psychiatrists working in MH services in Turkey and determine the relationship between stress, workload, and support during the COVID-19 pandemic. Subjects and methods An online questionnaire was sent to child and adult psychiatrists registered with Turkish professional mail groups. 217 psychiatrists replied, with equal numbers from child (n=108) and adult (n=109) MH services. The Copenhagen Burnout Inventory and study-specific questionnaire were used. Results 60.8% of psychiatrists (n=132) experienced medium-or high-intensity work-related burnout, 49.8% (n=108) experienced patient-related burnout, and 31.8% (n=69) experienced medium-or high-intensity personal burnout. Patient-related burnout scores were significantly higher in the child psychiatry group than in the adult psychiatry group. The majority (n=126, 58.1%) reported either moderate or higher stress levels linked to the COVID-19 pandemic. Turnover intention, reluctance to retrain in psychiatry and sense of lack of value in the job are all associated with higher levels of burnout. Conclusions The current COVID-19 pandemic is likely to bring additional stressors to psychiatrists. This study shows that psychiatrists in Turkey already exhibit high levels of work-related stress. Organizational interventions to ameliorate psychiatrists' wellbeing and work conditions are required.
