Objective: Nulliparous obese women are at increased risk of labor induction and cesarean delivery (CD). We sought to determine whether the combination of a transvaginal Foley balloon plus misoprostol prostaglandin E1 (PGE1) is superior to misoprostol alone in reducing the risk for CD., Study Design: We undertook a multicenter, open-label, comparative-effectiveness randomized clinical trial of nulliparous obese women with unfavorable cervix (Bishop's score ≤ 6) undergoing labor induction from January 2016 to June 2018 at three tertiary centers. Those at <32 weeks' gestation, premature rupture of membranes, stillbirth, and major fetal anomalies were excluded. Women were randomized 1:1 to either a combination of Foley balloon and misoprostol or misoprostol alone. Once Bishop's score was >6, further management was deferred to treating physicians. Primary outcome was the rate of CD. Secondary maternal outcomes included duration of induction-to-delivery interval, occurrence of tachysystole, clinical chorioamnionitis, need for operative vaginal delivery, as well as a composite of maternal morbidity (postpartum endometritis, surgical-site infection, venous thromboembolism, need for transfusion, intensive care unit admission, and maternal death). Secondary neonatal outcomes included need for neonatal intensive care unit admission, transient tachypnea of the newborn, respiratory distress syndrome, meconium aspiration syndrome, culture-proven sepsis, neonatal seizures, and a composite of neonatal morbidity (Apgar's score ≤7 at 5 minutes, umbilical artery cord pH ≤7.10, birth injury, perinatal death). With the rate of CD rate being 53% at Children's Memorial Herman Hospital among nulliparous obese women who underwent induction of labor at ≥32 weeks and met our inclusion criteria; 250 women (125 women per group) were required to answer the study question. All analyses were by intention to treat., Results: Of the 236 women randomized, 113 (48%) were allocated to group 1 (combined Foley and PGE1) and 123 (52%) to group 2 (PGE1 alone). The rate of CD was similar between the groups (45 vs. 43%, p  = 0.84, relative risk [RR]: 1.03, 95% CI: 0.75-1.42). There was no difference in the occurrence of tachysystole that resulted in fetal heart rate abnormalities between the groups (8.8 vs. 16.2%, p  = 0.09, RR: 0.54, 95% CI: 0.27-1.11). The total duration of the induction-to-delivery interval was also similar between the groups (24.8 ± 13.8 vs. 24.5 ± 14.0 hours, p  = 0.87) regardless of the mode of delivery. No differences were seen in the indications for CD and secondary maternal or neonatal outcomes., Conclusion: In this trial of nulliparous obese women undergoing labor induction, cervical ripening with combined Foley balloon and PGE1 resulted in similar CD rates than ripening with vaginal PGE1 alone., Key Points: · Nulliparous obese women are at increased risk for cesarean delivery.. · Combined intravaginal misoprostol-Foley balloon versus misoprostol alone resulted in similar rates of cesarean delivery.. · Further research is warranted to determine the optimal cervical ripening strategy in this population.., Competing Interests: None declared., (Thieme.

Objective: To assess whether assisted reproductive technology (ART) is associated with increased risk of adverse perinatal outcomes in triplet gestations compared with spontaneous conception., Study Design: Secondary analysis of a multicenter randomized trial for the prevention of preterm birth in multiple gestations. Triplets delivered at ≥ 24 weeks were studied. The primary outcome was the rate of composite neonatal morbidity (CNM) that included one or more of the following: bronchopulmonary dysplasia, respiratory distress syndrome, necrotizing enterocolitis, culture proven sepsis, pneumonia, retinopathy of prematurity, intraventricular hemorrhage, periventricular leukomalacia, or perinatal death., Results: There were 381 triplets (127 women) of which 89 patients conceived via ART and 38 patients spontaneously. Women with ART were more likely to be older, Caucasian, married, nulliparous, have higher level of education, and develop pre-eclampsia. Spontaneously conceived triplets were more likely to delivery at an earlier gestation (31.2 ± 3.5 vs 32.8 ± 2.7 weeks) ( p  = 0.009) with a lower birth weight ( p  < 0.001). After adjusting for confounders, no differences were noted in culture proven sepsis, perinatal death, CNM, respiratory distress syndrome, or Apgar score < 7 at 5 minutes. All remaining perinatal outcomes were similar., Conclusion: Triplets conceived by ART had similar perinatal outcomes compared with spontaneously conceived triplets., Competing Interests: None., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Diabetes complicates 6 to 7% of all pregnancies in the United States. Poor glycemic control is associated with multiple immediate and long-term adverse effects on both the mother and fetus. Although uniformity exists in the antenatal management of this disease, there is a paucity of evidence-based studies upon which to dictate the optimal time of delivery among affected women. The potential risks of delayed neonatal pulmonary maturation including respiratory distress syndrome and transient tachypnea of the newborn associated with early delivery must be balanced with the increased incidence of fetal demise, overgrowth, and birth injury related to diabetes in late gestations. Even among diabetic women with optimal glycemic control, the risk of stillbirth in the third trimester is considerably higher than their normal counterparts. The current paradigm of delaying delivery to 39 weeks in women with controlled and uncomplicated diabetes has been challenged by recent evidence advocating delivery by 38 weeks to improve perinatal outcomes. However, additional well-designed and adequately powered prospective studies are needed to better understand the short- and long-term implications of the optimal timing of delivery in this high-risk population. This article reviews the most current literature regarding the optimal timing of delivery in pregnancies complicated by diabetes mellitus and gestational diabetes mellitus., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Objective: This study aims to compare neonatal and long-term outcomes among preterm newborns from women with reported versus those who did not report substance abuse., Study Design: Secondary analysis of a trial of magnesium sulfate for cerebral palsy prevention. Cases were pregnant women who reported substance abuse, controls were those who denied it. Study outcomes included (1) composite neonatal morbidity, defined as any of the following: Apgar score ≤ 3 at 5 minutes, seizures, culture-proven sepsis, necrotizing enterocolitis grades 2 or 3, intraventricular hemorrhage grades 3 or 4, and/or death before discharge; (2) infant and childhood morbidity, defined as stillbirth or death by 1 year, or moderate/severe cerebral palsy by age of 2., Results: Among 1,972 women meeting the inclusion criteria, 197 (10%) reported substance abuse. Composite neonatal, infant, and childhood morbidity rates were similar between cases and controls. However, women reporting substance abuse who delivered between 32(0/7) and 36(6/7) weeks had a higher frequency of composite infant and childhood morbidity (6.5 vs. 1.0%; adjusted odds ratio, 6.5; 95% confidence interval, 1.14-36.99)., Conclusions: Preterm birth was associated with similar composite neonatal morbidity between cases and controls. After 32 weeks, self-reported substance abuse was associated with a sevenfold increase in the rates of stillbirth and long-term infant morbidity., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

Objectives: Substance abuse in pregnancy remains a major public health problem. Fetal teratogenicity results from the effect of these substances during fetal development, particularly when used in combination. This review will focus on and attempt to clarify the existing literature regarding the association of substance abuse on the development of congenital anomalies and the long-term implications in exposed offspring., Methods: Systematic review of available English literature using the PubMed database of all peer-reviewed articles on the subject., Results: A total of 128 articles were included in this review. Alcohol was the most common substance associated with fetal anomalies, particularly facial dysmorphisms and alterations in the central nervous system development. Adverse maternal environments associated with risky behaviors and lack of adequate prenatal care precludes the timely detection of fetal anomalies, confounding most studies linking causality. In addition, although methodological differences and limited availability of well-designed trials exist, substance abuse in pregnancy has been associated with adverse long-term outcomes in infant growth, behavior, cognition, language and achievement., Conclusion: The literature summarized in this review suggests that drug exposure during pregnancy may increase the risk of congenital anomalies and long-term adverse effects in exposed children and adolescents. These conclusions must be tempered by the many confounders associated with drug use. A multidisciplinary approach is paramount for appropriate counseling regarding the known immediate and long-term risks of substance abuse in pregnancy., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)
