Exploring the characteristics and antecedents of clinically significant long COVID: A longitudinal cohort study.

Background: A significant number of coronavirus disease 2019 (COVID-19) survivors are experiencing long COVID, with symptoms lasting beyond three months. While diverse long COVID symptoms are established, there are gaps in understanding its long-term trends, intensity, and risk factors, requiring further investigation.

Aims: This study aimed to investigate the long COVID characteristics and associated factors by following COVID-19 survivors for one year post-infection and comparing them with healthy counterparts.

Use of Multiple Doses of Intravenous Infusion of Umbilical Cord-Mesenchymal Stem Cells for the Treatment of Adult Patients with Severe COVID-19-Related Acute Respiratory Distress Syndrome: Literature Review.

Objectives: Acute respiratory distress syndrome (ARDS) is a critical complication in severe COVID-19 patients. The intravenous infusion (IVF) of umbilical cord- (UC-) mesenchymal stem cells (MSCs), validated to substantially reduce the release of several inflammatory cytokines , was also shown to exhibit benefits in improving hypoxemia among severe COVID-19 patients. A single dose of IVF-UC-MSCs therapy for severe COVID-19 patients was shown to alleviate the initial ARDS severity, but have 50%-67% case-fatality rates.

Clinical predictors of obstructive sleep apnea in Asian bariatric patients.

Background: Obstructive sleep apnea (OSA) is a common disorder in modern society and closely associated with obesity. Because OSA increases the likelihood of complications in the perioperative period, preoperative recognition is very important for bariatric patients. Polysomnography (PSG) remains the gold standard for diagnosis, but it is a time-consuming and expensive examination.

Initial otolaryngological manifestations of severe acute respiratory syndrome in Taiwan.

Objective: To provide a clue for screening severe acute respiratory syndrome (SARS), a highly transmissible disease with health care workers at particular risk, in the early stage from an otolaryngological perspective.

Design: Prospective study.

Setting: Community hospital.
