Knowledge and Perceptions about COVID-19 among Thai Classical Dancers in Thailand: An Online Cross-Sectional Survey.
The prevention and control of the spread of COVID-19 has become a major challenge and concern globally. Since the COVID-19 pandemic is still ongoing, sufficient knowledge and practices of people toward COVID-19 is necessary. Thai classical dancers are one of the groups affected by the pandemic. ⋯ Basic understanding about COVID-19 among Thai classical dancers based on their available resources is important. Hence, providing more valid sources of information and health literacy to Thai classical dancers should be considered. More studies on COVID-19 in other dancers should also be explored.

Low skeletal mass predicts poor prognosis of elderly patients after emergency laparotomy: A single Asian institution experience.
Sarcopenia, defined as low skeletal muscle mass and poor muscle function, has been associated with worse postoperative recovery. This study aims to evaluate the significance of low muscle mass in the elderly who require emergency surgeries and the postoperative outcomes. ⋯ Patients with low muscle mass have significantly higher post-surgical complication rates and increased mortality.

The significant immune escape of pseudotyped SARS-CoV-2 variant Omicron.
The emergence of Omicron/BA.1 has brought new challenges to fight against SARS-CoV-2. A large number of mutations in the Spike protein suggest that its susceptibility to immune protection elicited by the existing COVID-19 infection and vaccines may be altered. ⋯ Our results indicated that the mean neutralization ED50 of these sera against Omicron decreased to 66, which is about 8.4-folds compared to the D614G reference strain (ED50 = 556), whereas the neutralization activity of other VOC and VOI pseudotyped viruses decreased only about 1.2-4.5-folds. The finding from our in vitro assay suggest that Omicron variant may lead to more significant escape from immune protection elicited by previous SARS-CoV-2 infection and perhaps even by existing COVID-19 vaccines.

At what frequency of vaccination do the vaccinated potentially pose an equal risk to the unvaccinated for transmission of SARS-CoV-2 inside restaurants in New York City?
From August 2021 to 7 March 2022, New York City prohibited indoor dining in restaurants selectively for persons who had not received a Coronavirus disease 2019 (COVID-19) vaccine. However, vaccinated persons may also be actively infected and potentially transmit severe acute respiratory syndrome coronavirus 2 (SARS-CoV‑2). Based on assuming a 7:1 ratio of COVID-19 cases in New York State for the unvaccinated versus the vaccinated, it can be estimated that when 87.5% of adults in New York City are vaccinated, the rate of unsuspected SARS-CoV‑2 infections (asymptomatic or minimally symptomatic) among vaccinated adults going to restaurants would be equivalent to that for the unvaccinated.
