Effect of single embryo transfer on the risk of preterm birth associated with in vitro fertilization.

Purpose: To determine whether elective single embryo transfer (eSET) reduces the risk of preterm delivery associated with in vitro fertilization (IVF).

Methods: This is an observational study of 3125 eSET cycles performed from 2008 to 2009 and reported to the Society for Assisted Reproductive Technology (SART) database. Preterm delivery rates were compared to the overall preterm delivery rate among all patients undergoing IVF over the same time period.

Ertapenem compared to combination drug therapy for the treatment of postpartum endometritis after cesarean delivery.

Objective: Ertapenem is a broad spectrum carbapenem approved for the treatment of postpartum endometritis. Data regarding clinical outcomes after treatment with ertapenem for endometritis after cesarean delivery are limited. Our objectives were to compare clinical outcomes and cost of ertapenem versus a multi-drug regimen for treatment of endometritis after cesarean delivery.
