To identify trends and risk factors for early surgical site infection (SSI) following cesarean delivery (CD).A population-based study comparing characteristics of women who have not developed post SSI was conducted. Deliveries occurred between the years 1988 2013 in a tertiary medical center. A multivariable logistic regression model, with backwards elimination, used to control confounders.Of 41 375 deliveries performed during period, 1521 (3.7%) were complicated SSI. rates significantly...

Summary Objective Newborns exhibit the lowest immediate respiratory morbidity rates when born following 39 completed weeks of gestation. We sought to determine whether early‐term delivery (37–38 + 6 weeks’ gestation) impacts on long‐term pediatric morbidity. Study design In this population‐based prospective cohort analysis, all term singleton deliveries occurring between 1991 and 2013 at a single tertiary medical center were included. Gestational age upon was sub‐divided into: early...
