The effects of the COVID-19 outbreak on physicians' psychological resilience levels.
Health-care workers exposed to coronavirus19 disease could be psychologically stressed. The objective of this study is to assess the anxiety, depression levels, and psychological resilience of physicians working during the Covid-19 outbreak and to evaluate the related factors that are associated with their psychological resilience. ⋯ Depression and anxiety levels were found to be significantly lower in physicians with greater psychological resilience. Psychological and social support of all health-care workers, especially physicians, is important in the struggle with the pandemic. It is thought that determining the variables related to psychological resilience in health-care workers will be a guide for psychosocial services.

Does arterial stiffness affect orthostatic hypotension among high-altitude Tibetans?
This study aimed to investigate the association between arterial stiffness and orthostatic hypotension (OH) and orthostatic blood pressure (BP) changes among Tibetans living at high altitude. ⋯ BaPWV was significantly associated with the occurrence of OH and orthostatic changes in the SBP and DBP, which suggests that arterial stiffness may be a potential mechanism of impaired hemodynamic response to orthostatic challenges among high-altitude Tibetans.

The effect of cholecystectomy on the risk of acute myocardial infarction in patients with gallbladder stones.
Objectives: To investigate the effect of cholecystectomy on the subsequent risk of acute myocardial infarction (AMI) in patients with gallbladder stones (GBS). Methods: We used the Taiwan National Health Insurance Research Database (NHIRD) for hospitalization to conduct a retrospective nationwide population-based cohort study. The study cohort consisted of a total of 122,421 patients aged ≥20 years with cholecystectomy for GBS between 2000 and 2010. ⋯ Compared to those without cholecystectomy, the risk of developing AMI after cholecystectomy was 0.69 (95% CI = 0.63-0.76) for the first year, 0.69 (95% CI = 0.63-0.77) for 2-5 years, and 0.59 (95% CI = 0.53-0.66) for ≥5 years, respectively. Conclusions: Our findings indicate cholecystectomy ameliorates the risk of AMI in patients with GBS, and the protective effect tends to increase with incremental duration of follow-up. However, it needs more studies to ascertain the protective mechanisms of cholecystectomy against AMI.
