#1
Carolyn L Westhoff, Malcolm C Pike
The recent Danish cohort study reported a 20% increased risk of breast cancer among current and recent hormonal contraception users. These results are largely consistent with previous studies. This study did not report on stage of disease at diagnosis and it is not clear to what extent the apparent increased risk may be due to a small advance in the timing of diagnosis. This study did not report on the risk associated with the use of a 20-μg ethinyl estradiol pill. They did find an increasing risk in current users of longer duration and an increased risk with use of the levonorgestrel intrauterine system-both of these potentially important findings have not been consistently found in previous studies and require further investigation...

BACKGROUND: The optimal method for induction of labor for multiparous women with an unfavorable cervix is unknown. OBJECTIVE: To determine if induction of labor with simultaneous use of oxytocin and a cervical ripening balloon, compared with sequential use, increases the likelihood of delivery within 24 hours in multiparous women. STUDY DESIGN: We performed a randomized controlled trial between November 2014 and June 2017. Eligible participants were multiparous women with a vertex presenting, non-anomalous singleton gestation ≥ 34 weeks undergoing induction of labor...

Fiona L Mackie, Matthew J Hall, R Katie Morris, Mark D Kilby
OBJECTIVE: Assess ability of first trimester pregnancy related factors (ultrasound measurements, maternal characteristics, biomarkers) to predict complications in monochorionic twin pregnancies DATA SOURCES: MEDLINE, EMBASE, ISI Web of Science, CINAHL, the Cochrane Central Registration of Controlled Trials and Research Registers, and Google Scholar, from inception to 12 May 2017. Grey literature and bibliographies of articles were checked. STUDY ELIGIBILITY CRITERIA: Studies that reported ultrasound measurements, maternal characteristics, or potential biomarkers, measured in the first trimester in monochorionic diamniotic twin pregnancies, where the potential prognostic ability between the variable and twin-twin transfusion syndrome, growth restriction, or intrauterine fetal death could be assessed...

OBJECTIVE: Antenatal corticosteroids (ANS) are among the most important and widely used interventions to improve outcomes for preterm infants. ANS dosing regimens remain un-optimized and without maternal weight-adjusted dosing. We, and others, have hypothesised that once a low concentration of materno-fetal steroid exposure is achieved and maintained, the duration of the steroid exposure determines treatment efficacy. Using a sheep model of pregnancy, we tested the relationship between steroid dose, and duration of exposure, and treatment efficacy...

BACKGROUND: We sought to describe the relationship between the elimination of out-of-pocket costs and women's use of preventive care office visits and long-acting reversible contraception after accounting for baseline levels of cost sharing. OBJECTIVES: The objective of this analysis was to describe the relationship between the elimination of out-of-pocket costs and utilization of preventive care visits and long-acting reversible contraception insertion, while taking baseline cost sharing levels under consideration...

BACKGROUND: How race is associated with adverse outcomes in the setting of postpartum hemorrhage is not well characterized. OBJECTIVE: The objective of this study was to assess how race is associated with adverse maternal outcomes in the setting of postpartum hemorrhage. STUDY DESIGN: This retrospective cohort study utilized the National (Nationwide) Inpatient Sample (NIS) from the Agency for Healthcare Research and Quality for the years 2012 to 2014...

BACKGROUND: Swenson et al. developed a linear regression model to estimate postoperative day one (POD1) hematocrit (HCT) levels after benign hysterectomy. Predictive variables included pre-operative HCT, patient weight, estimated blood loss, intra-operative crystalloid volume, pre-operative platelet count, and hysterectomy route which predicted POD1 HCT ±5 for 100% of subjects using an internal validation set. OBJECTIVES: We aimed to externally validate the Swenson model using our hysterectomy population and to further validate the model in a cohort including robotic-assisted cases...

BACKGROUND: Length of stay (LOS) after surgery has become an important quality measure for many common surgical procedures and is now also tied to reimbursement. Currently, little is known about the perioperative factors that contribute to prolonged hospital LOS in women who undergo hysterectomy for benign conditions. OBJECTIVE: We performed a population-based analysis to investigate the association between perioperative factors and prolonged LOS in women undergoing minimally invasive, abdominal, and vaginal hysterectomy...

OBJECTIVE: To design and establish a uterine fibroid (UF) registry based in the United States (US) to provide comparative effectiveness data regarding UF treatment. STUDY DESIGN: We report here the design and initial recruitment for the Comparing Options for Management: Patient-centered Results for Uterine Fibroids (COMPARE-UF) registry (Clinicaltrials.gov, NCT02260752), funded by the Agency for Healthcare Research and Quality (AHRQ) in collaboration with the-Patient-Centered Outcomes Research Institute (PCORI)...

BACKGROUND: It is unclear whether a neonatal or a fetal growth standard is a better predictor of adverse in-hospital newborn outcomes. OBJECTIVE: We aimed to evaluate and compare the power of birth weight for gestational age to predict adverse neonatal outcomes using neonatal and fetal growth charts. Gestational age specific birth weight was examined either as a centile score or as a binary indicator for birth weight below the 10th centile (small for gestational age) using three fetal growth charts (National Institute of Child Health and Human Development, World Health Organization, and Intergrowth-21st ) and one neonatal sex-specific birth weight chart...

BACKGROUND: During labor, maintenance of maternal euglycemia is critical to decrease the risk of neonatal hypoglycemia and associated morbidities. When continuous intravenous insulin infusion is needed, standardized insulin dosing charts have been used for titration of insulin to maintain glucose in target range. GlucoStabilizer™ is a software-guided insulin dosing system that calculates the dose of intravenous insulin needed based on metabolic parameters, target glucose concentration, and an individual's response to insulin...
