Objective Understanding the clinical factors associated with the severity of coronavirus disease 2019 (COVID-19) is very important for the effective use of limited medical resources, including the appropriate evaluation of the need for hospitalization and discharge. Methods Patients hospitalized with a diagnosis of COVID-19 from March 2021 to October 2022 were included in the study. Patients admitted to our facility were classified into four waves: 4th (April to June 2021), 5th (July to October 2021), 6th (January to June 2022), and 7th waves (July to October 2022). ⋯ Further comparisons between the respiratory failure group (n=75) and the nonrespiratory failure group (n=471) revealed significant differences in the age, sex, vaccination history, and biomarker values between the two groups. Conclusion In this study, elderly men were found to be more likely to develop severe disease than others, and biomarkers of COVID-19, such as C-reactive protein and lactate dehydrogenase, were useful for predicting severity. This study also suggested that vaccination may have contributed to a reduced disease severity.

An 89-year-old woman with a giant hiatal hernia complained of persistent chest pain. An electrocardiogram (ECG) showed hyperacute T waves, suggesting the early phase of ST-elevation myocardial infarction. After endoscopic drainage for hiatal hernia, the chest pain disappeared, and the ECG abnormalities resolved. The present case illustrates that compression of the heart by a giant hiatal hernia can induce T wave elevation mimicking acute coronary syndrome.

Observational Study
A Comparison of the Physical Activity and Sedentary Behavior between Autologous and Allogeneic Hematopoietic Stem Cell Transplantation Survivors.
Objective The treatment background, as well as the frequency and type of complications, in autologous (auto-) and allogeneic (allo-) hematopoietic stem cell transplantation (HSCT) survivors influence the appearance of moderate to vigorous physical activity (MVPA) or sedentary behavior. We therefore assessed differences in the MVPA and sedentary behavior between auto- and allo-HSCT survivors. Methods This prospective observational study included 13 auto- and 36 allo-HSCT survivors (approximately 4 years after HSCT). ⋯ A stepwise multiple regression analysis showed that age was a significant predictor of sedentary behavior in allo-HSCT survivors (β=0.400, p=0.016). Conclusion We observed no significant between-group differences in the MVPA or sedentary behavior. Our results suggest that it may be unnecessary to change the rehabilitation program according to the donor type in interventions for promoting MVPA and reducing sedentary behavior in long-term HSCT survivors.

Objective During the coronavirus disease 2019 (COVID-19) pandemic period, an extended total activity time (TAT) in emergency cases has been reported, especially in febrile patients. A brief selection time (ST) regarding the transport of patients to designated hospitals is vital to achieving a good outcome. However, to our knowledge, no studies have reported the impact of the COVID-19 pandemic on the ST. ⋯ The difference-in-differences analyses showed that the mean ST increased by 2.52 minutes (p<0.001), the mean ART by 3.10 minutes (p<0.001), and the mean TAT by 7.27 minutes (p<0.001) for patients with a fever during the COVID-19 period. Conclusion This study showed that febrile patients had a longer ST, ART, and TAT during the 2020 COVID-19 period. Considering the COVID-19 pandemic and the threat of future pandemics, regional infection control and information-sharing should be conducted to reduce the EMS activity time.
