Wikipedia, the largest encyclopedia ever created, is a global initiative driven by volunteer contributions. When the COVID-19 pandemic broke out and mobility restrictions ensued across the globe, it was unclear whether contributions to Wikipedia would decrease in the face of the pandemic, or whether volunteers would withstand the added stress and increase their contributions to accommodate the growing readership uncovered in recent studies. We analyze [Formula: see text] million edits contributed from 2018 to 2020 across twelve Wikipedia language editions and find that Wikipedia's global volunteer community responded resiliently to the pandemic, substantially increasing both productivity and the number of newcomers who joined the community. For example, contributions to the English Wikipedia increased by over [Formula: see text] compared to the expectation derived from pre-pandemic data. Our work sheds light on the response of a global volunteer population to the COVID-19 crisis, providing valuable insights into the behavior of critical online communities under stress.

The current guidelines for cardiovascular disease prevention by the European Society of Cardiology highlight the undisputable benefits of exercise and a physically active lifestyle for cardiovascular risk reduction. In addition to the health benefits of physical activity, observational data suggests that regular physical activity lowers all-cause mortality. However, this was not confirmed by Mendelian randomization studies and randomized controlled trials.

Chronic pain (CP) is a major health issue globally, affecting millions and resulting in a significant healthcare burden. Although amitriptyline is widely used to manage CP, its immunomodulatory effects during pain therapy, especially on T cell phenotypes, remain unclear. In this study, we explored how amitriptyline alters T cell phenotypes in CP patients.

Background: Neural respiratory drive (NRD) is a clinically relevant biomarker in patients with chronic obstructive pulmonary disease (COPD). However, its analysis is challenging due to several technical considerations, including the need to obtain a stable recording over a short time period. However, a short recording duration may be inadequate to comprehensively record clinically relevant information, particularly during sleep, because NRD varies across sleep stages and over time.

Aim: To identify individuals at risk of falls and the factors contributing to their risk, we screened community-dwelling older adults using the Centers for Disease Control and Prevention's Stopping Elderly Accidents, Deaths, and Injuries (STEADI) Assessments.
Design: A descriptive correlational study design.
Methods: Fall risk screenings with community-dwelling older adults aged 65 or older were conducted during a virtual interprofessional education event (IPE) for fall risk screening.

Polycystic ovary syndrome (PCOS) is a multifactorial endocrine disorder associated with vascular dysfunction and increased cardiovascular risk. This study aims to investigate the dysregulation of vascular tone in PCOS, focusing on the imbalance between vasodilators (nitric oxide [NO] and apelin) and vasoconstrictors (noradrenaline and reduced prostacyclin). By examining these factors, the study seeks to elucidate their contribution to endothelial dysfunction and cardiovascular complications in PCOS patients.
