Early Gestational Weight Gain and the Risk of Preeclampsia in Dichorionic Twin Pregnancies.

Objective: The purpose of our study was to evaluate the body mass index (BMI)-specific association between early gestational weight gain (GWG) in dichorionic twin pregnancies and the risk of preeclampsia.

Study Design: We conducted a retrospective cohort study of all dichorionic twin pregnancies from 1998 to 2013. Data were obtained from a perinatal database and chart abstraction.

Patient Opinions About Foreign Body Contraceptives.

Prior studies have noted patient reluctance to use contraceptive devices that require insertion into their bodies. We sought to better understand this "foreign body" concern, as well as to clarify how women perceive long-acting reversible contraception (LARC) devices compared with other implanted medical devices. We performed semistructured qualitative individual interviews with female obstetric/gynecologic patients and probed their opinions regarding LARC devices.

Perinatal Outcomes Associated with Early Diabetes Testing in Pregnancies Complicated by Obesity.

Objective: This study aimed to determine whether early diabetes testing is associated with differences in perinatal outcomes among pregnant women with obesity (body mass index ≥30 kg/m).

Study Design: We conducted a retrospective cohort study of singleton pregnancies from 2012 to 2014 at a large academic medical center which examined the association of diabetes testing (HBA1c, 50 g glucose challenge test, or 100 g oral glucose tolerance test) before 24 weeks with perinatal outcomes using propensity score modeling and logistic regression.

Results: Among women with obesity, 790 out of 2,698 (29.

Antibiotic Use in Pregnancy, Abnormal Fetal Growth, and Development of Gestational Diabetes Mellitus.

Objective: Antibiotics are commonly used in pregnancy. Prior studies have indicated that antibiotic use in pregnancy may affect birth weight, whereas data in nonpregnant individuals suggest that antibiotic exposure may increase diabetes risk. We evaluated the impact of antibiotic prescriptions during pregnancy on the prevalence of small for gestational age (SGA) and large for gestational age (LGA) birth weight and gestational diabetes mellitus (GDM).

Antenatal Magnesium Sulfate Exposure and Ponderal Index in Preterm Infants.

Objective: Antenatal magnesium sulfate (MgSO) is known to affect the central nervous system of preterm infants, and there is biologic rationale for influence on other phenotypes. This study investigated the effect of MgSO exposure on the trajectory of ponderal index (PI, kg/m) from birth to 2 years of age.

Study Design: A secondary analysis of a U.
