Article Abstract

Obesity, characterized by chronic low-grade inflammation of the adipose tissue, is associated with adverse coronavirus disease 2019 (COVID-19) outcomes, yet the underlying mechanism is unknown. To explore whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection of adipose tissue contributes to pathogenesis, we evaluated COVID-19 autopsy cases and deeply profiled the response of adipose tissue to SARS-CoV-2 infection in vitro. In COVID-19 autopsy cases, we identified SARS-CoV-2 RNA in adipocytes with an associated inflammatory infiltrate. We identified two distinct cellular targets of infection: adipocytes and a subset of inflammatory adipose tissue-resident macrophages. Mature adipocytes were permissive to SARS-CoV-2 infection; although macrophages were abortively infected, SARS-CoV-2 initiated inflammatory responses within both the infected macrophages and bystander preadipocytes. These data suggest that SARS-CoV-2 infection of adipose tissue could contribute to COVID-19 severity through replication of virus within adipocytes and through induction of local and systemic inflammation driven by infection of adipose tissue-resident macrophages.

Prebunking can be used to pre-emptively refute conspiracy narratives. We developed a new approach to prebunking - fighting fire with fire - which introduces a plausible 'meta-conspiracy' suggesting that conspiracy theories are deliberately spread as part of a wider conspiracy. In two preregistered intervention studies, prebunking specific COVID-19 vaccine (Study 1, N = 720) and climate change (Study 2, N = 1077) conspiracy theories (e.

The assessment of the fibrinogen-to-platelet ratio for predicting mortality of COVID-19 in non-diabetic subjects.

Little is known about the biomarkers of mortality in SARS-CoV-2-infected patients without a previous diagnosis of diabetes. Thus, this study aimed to assess the fibrinogen-to-platelet ratio (FPR) and compare its predictive value with the main biomarkers for COVID-19 mortality, such as neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), leukocyte glucose index (LGI), and lactate dehydrogenase (LDH)/lymphocyte ratio. This retrospective cohort study in a population of Mexico included 70 non-diabetic patients with COVID-19 from 1 May 2020 to 30 September 2020.

Background: Children and adolescents with attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) often face structural and psychological barriers in accessing medical care, including economic costs, long wait times, and stress of attending new medical environments. The COVID-19 pandemic accelerated the adoption of telehealth services to overcome these challenges. However, few studies have assessed the satisfaction levels of children and adolescents diagnosed with neurodevelopmental disorders and their caregivers when they use telepsychiatry, particularly in Japan.

Since its discovery in the late 18th Century, the role of vaccination in preventing death and disease has expanded across many infectious diseases and cancer. Key to our understanding of vaccine immunogenicity and efficacy is knowledge of the immune system itself. Inborn Errors of Immunity (IEI) represent a heterogeneous group of disorders characterised by impaired function of the immune system.

Young adults in their 20s have shown slower uptake of COVID-19 vaccines relative to older adults, potentially endangering themselves and their communities. Despite this, little vaccine communication has specifically targeted this age group. This study explored why "20-somethings" in British Columbia (BC), Canada delayed COVID-19 vaccination, and how to better encourage their vaccine uptake.
