The effect of new antepartum weight gain guidelines and prepregnancy body mass index on the development of pregnancy-related hypertension.

We evaluated the impact of adherence to the new Institute of Medicine weight gain guidelines within each prepregnancy body mass index (PPBMI) category on the development of pregnancy-related hypertension (PRH). Patients with singleton term deliveries (≥37 weeks) with documented PPBMI and pregnancy weight gain information were identified from a database of women enrolled for outpatient nursing services. Included were women without history of cardiovascular disease, PRH, or diabetes at initiation of services (N = 7676).

Antenatal factors predicting subsequent need for insulin treatment in women with gestational diabetes.

Objective: To identify characteristics indicative of subsequent requirement of insulin in patients with gestational diabetes (GDM).

Methods: Identified from a database were patients with GDM not receiving insulin or oral hypoglycemic agents at enrollment for outpatient education and surveillance. Maternal characteristics were compared between patients achieving glycemic control with diet and those requiring insulin.

Antepartum uterine contraction patterns in twin pregnancies with and without preterm labor and delivering before or after 36 weeks.

Objective: The purpose of this study was to identify differences in antepartum uterine contraction frequency (UCF) in twin pregnancies with and without preterm labor (PTL).

Study Design: Twin gestations enrolled for outpatient surveillance with twice daily electronic uterine activity monitoring and telephonic nursing assessment, without interventional delivery were identified. Mean UCF for each gestational week was compared between women without PTL or preterm delivery (PTD) < 36 weeks (controls) and those with a PTL diagnosis delivering at < 36 weeks (PTL/PTD group), and those with PTL with delivery > or = 36 weeks (PTL/GAD > or = 36 group).
