RESUMEN
OBJECTIVE: To evaluate the association of Oregon's hard-stop policy limiting early elective deliveries (before 39 weeks of gestation) and the rate of elective early-term inductions and cesarean deliveries and associated maternal-neonatal outcomes. METHODS: This was a population-based retrospective cohort study of Oregon births between 2008 and 2013 using vital statistics data and multivariable logistic regression models. Our exposure was the Oregon hard-stop policy, defined as the time periods prepolicy (2008-2010) and postpolicy (2012-2013). We included all term or postterm, cephalic, nonanomalous, singleton deliveries (N=181,034 births). Our primary outcomes were induction of labor and cesarean delivery at 37 or 38 weeks of gestation without a documented indication on the birth certificate (ie, elective early term delivery). Secondary outcomes included neonatal intensive care unit admission, stillbirth, macrosomia, chorioamnionitis, and neonatal death. RESULTS: The rate of elective inductions before 39 weeks of gestation declined from 4.0% in the prepolicy period to 2.5% during the postpolicy period (P<.001); a similar decline was observed for elective early-term cesarean deliveries (from 3.4% to 2.1%; P<.001). There was no change in neonatal intensive care unit admission, stillbirth, or assisted ventilation prepolicy and postpolicy, but chorioamnionitis did increase (from 1.2% to 2.2%, P<.001; adjusted odds ratio 1.94, 95% confidence interval 1.80-2.09). CONCLUSIONS: Oregon's statewide policy to limit elective early-term delivery was associated with a reduction in elective early-term deliveries, but no improvement in maternal or neonatal outcomes.

OBJECTIVE: To examine birthweight and other predictors of brachial plexus injury (BPI) among births complicated by shoulder dystocia. STUDY DESIGN: A retrospective cohort study of term births complicated by shoulder dystocia in California between 1997 and 2006. Birthweight at time of delivery was stratified into 500-g intervals. Women were further stratified by diabetes status, parity, and race/ethnicity. The perinatal outcome of BPI was assessed. RESULTS: This study included 62,762 deliveries complicated by shoulder dystocia, of which 3168 (5 %) resulted in BPI. The association between birthweight and BPI remained significant regardless of confounders. Each increasing birthweight interval was associated with an increasing risk of BPI compared with 3000-3499-g birthweight. Race/ethnicity, diabetes, and parity were also independently associated with BPI. CONCLUSION: Increasing birthweight increases the risk of BPI among births with shoulder dystocia, independent of advanced maternal age, race, parity, gestational diabetes, or operative vaginal delivery.

BACKGROUND: The objective of this study was to examine the epidemiology of syphilis among high-risk socially marginalized populations in urban, coastal Peru, to quantify the prevalence of recent syphilis infection and identify risk factors. METHODS: Survey data and serologic specimens were collected from a population-based sample of 3 populations: men who have sex with only men (MSOM), socially marginalized heterosexual men, and socially marginalized women. Syphilis prevalence was determined for each population, and multivariate analysis was used to analyze risk factors for recent syphilis infection among the MSOM and among the socially marginalized men. RESULTS: The prevalence of recent syphilis infection was 10.5% among the MSOM, 1.5% among the socially marginalized men, and 2.0% among the women. Among both MSOM and the socially marginalized men, recent syphilis infection was significantly associated with Herpes simplex virus Type 2 infection (prevalence ratio = 1.96; 95% confidence interval, 1.03-3.74, and PR = 3.72; 95% CI, 2.12-6.53, respectively). Recent syphilis infection was also significantly associated with HIV infection among the socially marginalized men (PR = 11.13; 95% CI, 4.50-27.51) and with the number of sexually active years among the MSOM (PR = 1.05, 95% CI, 1.01-1.10). CONCLUSIONS: All 3 groups included in this study exhibited a high prevalence of recent syphilis infection, with recent infection being most prevalent among the MSOM. These findings demonstrate the need for more effective syphilis control services among those populations, to decrease syphilis-associated morbidity, transmission of syphilis, and the potential transmission of HIV.
