Maternal and neonatal outcomes after antenatal corticosteroid administration for PPROM at 32 to 33 6/7 weeks gestational age.

Background: Preterm Premature Rupture of Membranes (PPROM) precedes many deliveries and experts agree with expectant management until 34 weeks gestation. However, there is controversy regarding the gestational age (GA) for administration of corticosteroids.

Study Design: We performed a retrospective cohort study in the University of California Fetal Consortium (UCfC).

The interaction between maternal race/ethnicity and chronic hypertension on preterm birth.

Background: In both the biomedical and public health literature, the risk for preterm birth has been linked to maternal racial/ethnic background, in particular African-American heritage. Despite this well-documented health disparity, the relationship of comorbid conditions, such as chronic hypertension, to maternal race/ethnicity and preterm birth has received relatively limited attention in the literature.

Objective: The objective of the study was to evaluate the interaction between chronic hypertension and maternal racial/ethnic background on preterm birth.

Perinatal outcomes in the setting of active phase arrest of labor.

Objective: To examine the association between active phase arrest and perinatal outcomes.

Methods: This was a retrospective cohort study of women with term, singleton, cephalic gestations diagnosed with active phase arrest of labor, defined as no cervical change for 2 hours despite adequate uterine contractions. Women with active phase arrest who underwent a cesarean delivery were compared with those who delivered vaginally, and women who delivered vaginally with active phase arrest were compared with those without active phase arrest.
