    BACKGROUND: In 2010 the Consortium on Safe Labor published labor curves. It was proposed that the rate of cesarean delivery could be lowered by avoiding the diagnosis of arrest of dilation before 6 cm. However, there is little information on the uptake of the guidelines and on changes in cesarean delivery rates that may have occurred.

    OBJECTIVE: The objective of the study was to test the following hypotheses: (1) among patients laboring at term, rates of arrest of dilation disorders have ...

    OBJECTIVE: To test the hypothesis that use of the Foley bulb plus vaginal misoprostol will result in shorter induction-to-delivery time compared with vaginal misoprostol alone.

    METHODS: We randomized 123 women undergoing induction of labor with singleton pregnancies at 24 weeks of gestation or greater with an unfavorable cervix (Bishop score 6 or lower) to Foley bulb plus vaginal misoprostol (n=56) or vaginal misoprostol alone (n=61). Women with fetal malpresentation, multifetal ...

    Importance: Obesity increases the risk of both cesarean delivery and surgical-site infection. Despite widespread use, it is unclear whether prophylactic negative pressure wound therapy reduces surgical-site infection after cesarean delivery in obese women.

    Objective: To evaluate whether prophylactic negative pressure wound therapy, initiated immediately after cesarean delivery, lowers the risk of surgical-site infections compared with standard wound dressing in obese women.

    Importance: Two-thirds of women in labor receive supplemental oxygen to reverse perceived fetal hypoxemia and prevent acidemia. Oxygen is routinely administered for category II fetal heart tracings, a class of fetal tracing used to designate intermediate risk for acidemia. This liberal use of oxygen may not be beneficial, particularly because neonatal hyperoxygenation is harmful.

    Objective: To test the hypothesis that room air is noninferior to oxygen in improving fetal metabolic status ...

    BACKGROUND: Intrapartum electronic fetal monitoring is the most commonly used tool in obstetrics in the United States; however, which electronic fetal monitoring patterns predict acidemia remains unclear.

    OBJECTIVE: This study was designed to describe the frequency of patterns seen in labor using modern nomenclature, and to test the hypothesis that visually interpreted patterns are associated with acidemia and morbidities in term infants. We further identified patterns prior to delivery, ...

    BACKGROUND: Despite decades of attempts to link infectious agents to preterm birth, an exact causative microbe or community of microbes remains elusive. Nonculture 16S ribosomal RNA gene sequencing suggests important racial differences and pregnancy specific changes in the vaginal microbial communities. A recent study examining the association of the vaginal microbiome and preterm birth documented important findings but was performed in a predominantly white cohort. Given the important ...

    OBJECTIVE: To assess whether loop electrosurgical excision procedure (LEEP) increases the risk for preterm birth before 37 weeks of gestation and clarify whether the increased risk for preterm birth is attributable to the procedure itself or to risk factors associated with cervical dysplasia.

    DATA SOURCES: Two authors performed a search of the relevant data through February 2013 using PubMed, Embase, Scopus, CENTRAL, and ClinicalTrials.gov.

    BACKGROUND: Preterm birth is considered a multifactorial condition; however, emerging evidence suggests that genetic variation among individuals may have an important role. Prior studies have suggested that single-nucleotide polymorphisms associated with genes related to the immune system, and particularly the maternal inflammatory response, may be associated with an increased risk of preterm delivery.

    OBJECTIVE: The objective of the study was to identify single-nucleotide polymorphisms ...

    OBJECTIVE: We test the hypothesis that first-trimester serum analytes, 4-D power Doppler placental vascular indices and uterine artery Doppler (UAD) predicts abnormal placental morphometry in pregnancies with preeclampsia (PE) and fetal growth restriction (FGR).

    STUDY DESIGN: Maternal serum analytes (PAPP-A, hCG, ADAM12s, and PP13), bilateral UADs, and placental vascular indices were measured at 11-14 weeks in a nested-case control study within a prospective cohort of women followed from ...

    OBJECTIVE: The objective of the study was to assess the effect of prophylactic negative-pressure wound therapy on surgical site infections and other wound complications in women after cesarean delivery.

    DATA SOURCES: We searched Ovid Medline, Embase, SCOPUS, Cochrane Database of Systematic Reviews, and ClinicalTrials.gov.

    STUDY ELIGIBILITY CRITERIA: We included randomized controlled trials and observational studies comparing prophylactic negative-pressure wound therapy with standard ...

    OBJECTIVE: The evidence for delivering small-for-gestational-age (SGA) fetuses at 37 weeks remains conflicting. We examined the risk of stillbirth per week of gestation beyond 37 weeks for pregnancies complicated by SGA.

    STUDY DESIGN: Singleton pregnancies undergoing routine second trimester ultrasound from 1990-2009 were examined retrospectively. The risk of stillbirth per 10,000 ongoing SGA pregnancies with 95% confidence intervals (CIs) was calculated for each week of gestation ≥37 ...

    OBJECTIVE: To estimate the risk of adverse perinatal outcomes among women with isolated fetal growth restriction from 17 to 22 weeks of gestation.

    METHODS: This was a retrospective cohort study of all singleton, nonanomalous pregnancies undergoing ultrasonography to assess fetal anatomy between 17 and 22 weeks of gestation at a single center from 2010 to 2014. After excluding patients with fetal structural malformations, chromosomal abnormalities, or identified infectious etiologies, we ...

    The human placenta is key to pregnancy outcome, and the elevated oxidative stress present in many complicated pregnancies contributes to placental dysfunction and suboptimal pregnancy outcomes. We tested the hypothesis that pomegranate juice, which is rich in polyphenolic antioxidants, limits placental trophoblast injury in vivo and in vitro. Pregnant women with singleton pregnancies were randomized at 35∼38 wk gestation to 8 oz/day of pomegranate juice or apple juice (placebo) until the ...

    OBJECTIVE: To characterize the duration of the third stage of labor and the association with postpartum hemorrhage in a contemporary cohort.

    METHODS: We performed a secondary analysis of a cohort of 7,121 women who had a vaginal delivery at or beyond 37 weeks 0 days of gestation at a single tertiary care center from April 2010 to August 2014. Active management of the third stage of labor was routinely used during the study period. The mean, median, interquartile range, 90th percentile, ...

    BACKGROUND: Despite decades of attempts to link infectious agents to preterm birth, an exact causative microbe or community of microbes remains elusive. Culture-independent sequencing of vaginal bacterial communities demonstrates community characteristics are associated with preterm birth, although none are specific enough to apply clinically. Viruses are important components of the vaginal microbiome and have dynamic relationships with vaginal bacterial communities. We hypothesized that ...
