Comparative StudyThe effect of live and web-based education on the accuracy of blood-loss estimation in simulated obstetric scenarios.
Visual estimation of blood loss has been shown to be inaccurate. The objective of this study was to evaluate the impact of a didactic training program on the accuracy of the estimation of blood loss and to compare the effectiveness of training provided by a web-based vs live session. ⋯ Our study supports the use of live or web-based training to improve blood loss estimation accuracy.

Evidence of a gene-environment interaction that predisposes to spontaneous preterm birth: a role for asymptomatic bacterial vaginosis and DNA variants in genes that control the inflammatory response.
We determined whether an environmental exposure to bacterial vaginosis (BV) modified genetic susceptibilities for spontaneous preterm delivery within genes that regulate the inflammatory response. ⋯ These results demonstrate that the risk of preterm delivery that is associated with tag SNPs in genes that regulate the inflammatory response is modified by an environmental exposure such as bacterial vaginosis.

The purpose of this study was to estimate the incidence of postpartum hemorrhage (PPH) in the United States and to assess trends. ⋯ Population-based surveillance data signal an apparent increase in PPH caused by uterine atony. More nuanced clinical data are needed to understand the factors that are associated with this trend.
