Early outcomes and complications following cardiac surgery in patients testing positive for coronavirus disease 2019: An international cohort study
The outbreak of severe acute respiratory syndromecoronavirus-2, the cause of coronavirus disease 2019 (COVID-19) in December 2019 represented a global emergency accounting for more than 2.5 million deaths worldwide.1 It has had an unprecedented influence on cardiac surgery internationally, resulting in cautious delivery of surgery and restructuring of services.2 Understanding the influence of COVID-19 on patients after cardiac surgery is based on assumptions from other surgical specialties and single-center studies. The COVIDSurg Collaborative conducted a multicenter cohort study, including 1128 patients, across 235 hospitals, from 24 countries demonstrating perioperative COVID-19 infection…

Anti-atherogenic Effects of 17β-Estradiol
Estrogens are secreted primarily by the ovaries and placenta, by the testes in men and also produced by peripheral steroidogenic conversion. The 3 major naturally occurring estrogens are: 17β-estradiol (E2), estrone and estriol, of which E2 is the predominant and most active. The actions of E2 are mediated by at least 3 different receptors - the classical ERs (ERα and ERβ) and G-protein coupled receptor 30 (GPR30). E2 signaling in cardiomyocytes involves ERα- and ERβ-independent pathways, and treatment with the E2 receptor antagonists (Selective Estrogen Receptor Modulators- SERMs), which are agonists of GPR30, inhibits cardiac cell growth. Effects of E2 in preventing endothelial dysfunctio…
