TL;DR: Treatment of mild gestational diabetes mellitus did not significantly reduce the frequency of a composite outcome that included stillbirth or perinatal death and several neonatal complications, but it did reduce the risks of fetal overgrowth, shoulder dystocia, cesarean delivery, and hypertensive disorders.
Journal ArticleDOI

TL;DR: The number of intended pregnancies should be considered during counseling regarding elective repeat cesarean operation versus a trial of labor and when debating the merits of elective primary cESarean delivery.
Journal ArticleDOI

TL;DR: In this paper, a double-blind, placebo-controlled trial involving pregnant women with a documented history of spontaneous preterm delivery was conducted, where women were enrolled at 19 clinical centers at 16 to 20 weeks of gestation.
Journal ArticleDOI

TL;DR: In the context of prenatal diagnostic testing, chromosomal microarray analysis identified additional, clinically significant cytogenetic information as compared with karyotyping and was equally efficacious in identifying aneuploidies and unbalanced rearrangements but did not identify balanced translocations and triploidy.
Journal ArticleDOI
Maternal and Perinatal Outcomes Associated with a Trial of Labor after Prior Cesarean Delivery
Mark B. Landon,John C. Hauth,Kenneth J. Leveno,Catherine Y. Spong,Sharon Leindecker,Michael W. Varner,Atef H. Moawad,Steve N. Caritis,Margaret Harper,Ronald J.

Gabbe +21 more
TL;DR: The proportion of women who attempt vaginal delivery after prior cesarean delivery has decreased largely because of concern about safety, and the absolute and relative risks associated with a trial of labor in women with a history of cesAREan delivery are uncertain.
