Impact of the COVID-19 pandemic on mental health of pregnant women with diabetes mellitus and hypertension.
Psychological effects of the coronavirus disease 2019 (COVID-19) pandemic on pregnant women with diabetes and hypertension are not yet studied. Besides the pregnancy, these women have additional risk factors for severe acute respiratory syndrome due to COVID-19 and are considered a particularly vulnerable, unique population. We aimed to assess their mental health during this pandemic. ⋯ Pregnant women with diabetes and hypertension presented high levels of anxiety and depressive symptoms during the COVID-19 pandemic. Considering that these symptoms can affect both the mother's and offspring's health, it is necessary to implement tools to improve their mental health.

The effectiveness of dexamethasone on the prognosis of dialysis patients with severe COVID-19.
This study aimed to investigate the effectiveness of dexamethasone in dialysis patients with COVID-19 and whether it predicts mortality. ⋯ Dexamethasone did not reduce mortality rates and the requirement for intensive care unit in dialysis patients with COVID-19. Larger prospective randomized clinical trials are required to associate personalized medicine with the corticosteroid treatment to select suitable patients who are more likely to show a benefit.

Association between fragmented QRS and postprocedural rhythm disturbances in patients who underwent transcatheter aortic valve implantation.
According to recent studies, the rate of atrioventricular block requiring permanent pacing in patients following transcatheter aortic valve implantation varied between 5.7% and 42.5%. Fragmented QRS is a useful marker of myocardial scar and can predict adverse cardiac events. In this study, we examined association between f ragmented QRS and postprocedural rhythm disturbances and the need for permanent pacing in patients who underwent transcatheter aortic valve implantation. ⋯ Our data showed an increased risk for the development of new-onset left bundle branch block and atrioventricular blocks following transcatheter aortic valve implantation in patients whose baseline electrocardiogram recordings demonstrated QRS fragmentation.
