Neutralizing Antibodies and Cellular Immune Responses Against SARS-CoV-2 Sustained One and a Half Years After Natural Infection.

Background: COVID-19 has caused more than 2.6 billion infections and several million deaths since its outbreak 2 years ago. We know very little about the long-term cellular immune responses and the kinetics of neutralizing antibodies (NAbs) to SARS-CoV-2 because it has emerged only recently in the human population.

General recommendation for assessment and management on the risk of glucocorticoid-induced osteonecrosis in patients with COVID-19.

Background/objective: Coronavirus disease 2019 (COVID-19) is a disaster in human medical history and glucocorticoids remain the most promising therapy. Osteonecrosis is a disease caused by reduced intraosseous blood flow to bones in the joints, which will rapidly induce joint destruction. Approximately one-third patients with severe acute respiratory syndrome (SARS) who received high cumulative doses and long treatment durations of glucocorticoids occurred osteonecrosis.

The feasibility of at-home sleep extension in adolescents and young adults: A meta-analysis and systematic review.

Insufficient sleep duration is detrimental to health and performance and is alarmingly common in adolescents and young adults. The aim of this pre-registered meta-analysis was to determine the feasibility of at-home sleep extension as a means to improve sleep duration and daytime sleepiness, and maintain or improve sleep quality and efficiency, in adolescents and young adults. Peer-reviewed journal articles and dissertations were screened to identify studies with at least five consecutive days of at-home sleep extension, pre- and post-extension measurement of sleep duration, and participants 13-30 years of age.

Risk factors and prevention strategies for the occupational exposure of medical staff during the coronavirus disease-19 pandemic (Review).

During the sudden epidemic of this novel coronavirus-induced pneumonia, a number of medical staff were infected and even succumbed to coronavirus disease-19 (COVID-19). Based on the experience of medical professionals from The Hubei 672 Orthopedics Hospital of Integrated Chinese and Western Medicine on this COVID-19 pandemic, the present review summarizes the risk factors associated with the occupational exposure of front-line medical staff. Challenges encountered include insufficient understanding, lack of early protection, environmental factors and routine procedures and the lack of adequate prevention strategies.

Adherence to cultural values and the internalization of sociocultural appearance ideals are associated with exercise dependence symptoms in Asian/Asian American men.

This study examined sociocultural correlates of exercise dependence symptoms (EDSX) in young Asian/Asian American men. We hypothesized that greater adherence to Asian cultural values would be positively associated with EDSX and that the internalization of muscularity and thinness appearance ideals would exacerbate this link. Participants included 266 Asian/Asian American men (18-30y, Mage = 24.
