COVID-19 Outbreak and Its Association with Healthcare Workers' Emotional Stress: a Cross-Sectional Study.
The coronavirus disease 2019 (COVID-19) outbreak has exposed healthcare workers to extreme physical workloads and psychological challenges. Thus, we aimed to assess the immediate correlates of emotional stress and to identify which specific jobs, departments, and exposure types are risk factors for emotional stress in healthcare workers. ⋯ The COVID-19 outbreak is correlated with healthcare workers' emotional stress, and specific types of jobs and duties involving close contact with these patients can be risk factors. Interestingly, even low-exposure groups reported significant depression and anxiety as a result of social stigma and uncertainty. Adequate and timely management measures for emotional stress are required for vulnerable and at-risk groups.

Strategy for Prostate Cancer Patients with Low Prostate Specific Antigen Level (2.5 to 4.0 ng/mL).
To evaluate the strategy for detection of prostate cancer (PCa) with low prostate specific antigen (PSA) level (2.5-4.0 ng/mL), prostate biopsy patients with low PSA were assessed. We evaluated the risk of low PSA PCa and the strategy for screening low-PSA patients. ⋯ The PCa detection rate in the low-PSA group was not lower than that of previous studies of patients with PSA from 4.0 to 10.0 ng/mL. Further, it may be helpful to define a strategy for PCa detection using PSAD in the low-PSA group.

Bladder Regeneration Using a Polycaprolactone Scaffold with a Gradient Structure and Growth Factors in a Partially Cystectomized Rat Model.
Tissue engineering can be used for bladder augmentation. However, conventional scaffolds result in fibrosis and graft shrinkage. This study applied an alternative polycaprolactone (PCL)-based scaffold (diameter = 5 mm) with a noble gradient structure and growth factors (GFs) (epidermal growth factor, vascular endothelial growth factor, and basic fibroblast growth factor) to enhance bladder tissue regeneration in a rat model. ⋯ This study showed that a PCL scaffold with a gradient structure incorporating GFs improved bladder regeneration functionally and histologically.

Incidence and Mortality Rates of Thoracic Aortic Dissection in Korea - Inferred from the Nationwide Health Insurance Claims.
Aortic dissection (AD) is one of the most catastrophic diseases and is associated with high morbidity and mortality. The aim of this study is to investigate the hospital incidence and mortality rates of thoracic AD in Korea using a nationwide database. ⋯ The incidence of thoracic AD has gradually increased in Korea. The in-hospital mortality in the TASR subgroup decreased over the decade, although the overall mortality of AD patients did not change.
