It has prompted global efforts in research, with focus on the pathophysiology of coronavirus disease-19 (COVID-19), and a rapid surge of publications. COVID-19 has been associated with a myriad of clinical manifestations, including the lungs, heart, kidneys, central nervous system, gastrointestinal system, skin, and blood coagulation abnormalities. The endothelium plays a key role in organ dysfunction associated with severe infection, and current data suggest that it is also involved in SARS-CoV-2-induced sepsis. This critical review aimed to address a possible unifying mechanism underlying the diverse complications of COVID-19 microvascular dysfunction, with emphasis on the renin-angiotensin system. In addition, research perspectives are suggested in order to expand understanding of the pathophysiology of the infection. Although previous studies have found a relationship between having a preterm birth and maternal depression, methodologic issues may have limited the generalizability of results. Thus, the purpose of this study was to evaluate the relationship between having a preterm birth and postpartum depressive symptoms using a large, population-based sample of U.S. women. This secondary data analysis used 2012-2014 U.S. Pregnancy Risk Assessment Monitoring System data (N=89,366). Data on the exposure, preterm birth, were obtained from birth certificates. Infants born at 32 to less than 37weeks' gestation were considered moderate to late preterm, infants born at 28 to less than 32 full weeks' gestation were considered very preterm, and infant born at less than 28 full weeks' gestation were considered extremely preterm. To assess the outcome, two Pregnancy Risk Assessment Monitoring System questions measuring postpartum depressive symptoms were used. Logistic regressio
