INTRODUCTION AND HYPOTHESIS: We tested the null hypothesis that there were no differences between patients with obstetric fistula and parous controls without fistula. METHODS: A unmatched case-control study was carried out comparing 75 women with a history of obstetric fistula with 150 parous controls with no history of fistula. Height and weight were measured for each participant, along with basic socio-demographic and obstetric information. Descriptive statistics were calculated and differences between the groups were analyzed using Student's t test, Mann-Whitney U test where appropriate, and Chi-squared or Fisher's exact test, along with backward stepwise logistic regression analyses to detect predictors of obstetric fistula...

INTRODUCTION AND HYPOTHESIS: Catheterization type among women laboring with epidural analgesia who develop bladder retention has been reported to affect labor duration and mode of delivery. We aimed to compare the effect of continuous bladder catheterization (CC) with that of intermittent bladder catheterization (IC) on the duration of the second stage of labor. METHODS: In a randomized trial, term nulliparous women with singleton gestation who requested epidural analgesia and were unable to void spontaneously were eligible and randomized to either CC or IC...

BACKGROUND: Retinopathy of prematurity (ROP) is an adverse outcome of preterm birth (PTB) and is a leading cause of childhood blindness. The relationship between the subtypes of PTB with ROP is understudied. OBJECTIVE: To investigate if there is a difference in the incidence of type 1 or type 2 ROP in infants with PTB resulting from spontaneous preterm labor (SPTL), a medical indication (MIPTB), or preterm-premature rupture of the membranes (PPROM). STUDY DESIGN: A retrospective cohort study of 827 infants screened for ROP who delivered at a single tertiary care center in Colorado...

OBJECTIVE: Increasing body mass index (BMI) and administered doses of oxytocin are related to maternal and neonatal morbidities. We evaluated the effect of oxytocin dosage, BMI, and their interaction on select perinatal outcomes. STUDY DESIGN: We retrospectively studied nulliparas with singletons ≥36 weeks' gestation who received oxytocin and reached the second stage of labor. Oxytocin dosage was defined by the oxytocin product ([maximum oxytocin dose] X [duration of oxytocin infusion]/100 (milliunits))...

Attachment anxiety is associated with greater perceived physical pain, whereas social support is associated with lower pain perceptions. Few studies, however, have examined the joint effects of attachment and support on acute physical pain in a dyadic context. In this study, first-time expectant mothers (N=140) and their male partners completed romantic attachment measures (prenatally) and postnatal assessments of women's pain and men's emotional support during labor and delivery. More securely attached women benefited from emotional support in terms of reduced pain, more avoidantly attached women reported greater pain when given more support, and more anxiously attached women reported greater pain, regardless of their partner's support...

BACKGROUND: Preterm birth (PTB) is the leading cause of neonatal morbidity and mortality in non-anomalous neonates in the US. Women with a previous early spontaneous PTB are at highest risk for recurrence. Weekly intramuscular 17-alpha hydroxyprogesterone caproate (17-OHPC) reduces the risk of recurrent prematurity. Though current guidelines recommend 17-OHPC initiation between 16-20 weeks', in clinical practice, 17-OHPC is started across a spectrum of gestational ages. OBJECTIVE: To examine the relationship between the gestational age at 17-OHPC initiation and recurrent PTB among women a prior spontaneous PTB 16-28 weeks' gestation...

BACKGROUND: Approximately 1/3 of all deliveries in the United States are via cesarean. Previous research indicates weight gain during pregnancy is associated with an increased risk of cesarean delivery. It remains unclear, however, whether and to what degree weight gain between deliveries (i.e., inter-delivery weight gain) is associated with cesarean delivery in a subsequent pregnancy following a vaginal delivery. OBJECTIVES: To determine whether inter-delivery weight gain is associated with an increased risk of intrapartum cesarean delivery following a vaginal delivery...

BACKGROUND: Oxytocin is a potent uterotonic agent that is widely used for induction and augmentation of labor. Oxytocin has a narrow therapeutic index and the optimal dosing for any individual woman varies widely. OBJECTIVE: The objective of this study was to determine if genetic variation in the oxytocin receptor (OXTR) or in the gene encoding G protein-coupled receptor kinase 6 (GRK6), which regulates desensitization of the OXTR, could explain variation in oxytocin dosing and labor outcomes among women being induced near term...

BACKGROUND: When delivery is indicated prior to 34 weeks, many providers perform a cesarean delivery (CD) rather than induce labor based on perceptions of a high failure rate. Given the morbidity of CD, an accurate estimate of the success rate and factors associated with success in preterm induction of labor (IOL) is important in management decisions. OBJECTIVE: We sought to develop a prediction model for successful induction of labor in preterm patients using factors known at the time the decision is made to deliver...

BACKGROUND: In 2008, the Indian government introduced financial assistance to encourage health facility deliveries. Facility births have increased, but maternal and neonatal morbidity and mortality have not decreased raising questions about the quality of care provided in facilities and access to a quality referral system. We evaluated the potential role of inter-institutional transfers of women admitted for labor and delivery on adverse maternal and neonatal outcomes in an ongoing prospective, population-based Maternal and Newborn Health Registry in Central India...
