Abstract Background In the Twin Birth Study, women at 320/7–386/7 weeks of gestation, in whom the first twin was in cephalic presentation, were randomized to planned vaginal delivery or cesarean section. The study found no significant differences in neonatal or maternal outcomes in the two planned mode of delivery groups. We aimed to compare neonatal and maternal outcomes of twin gestations without spontaneous onset of labor, who underwent induction of labor or pre-labor cesarean section as the intervention of induction may affect outcomes. Methods In this secondary analysis of the Twin Birth Study we compared those who had an induction of labor with those who had a pre-labor cesarean section. The primary outcome was a composite of fetal or neonatal death or serious neonatal morbidity. Secondary outcome was a composite of maternal morbidity and mortality. Trial Registration: NCT00187369. Results Of the 2804 women included in the Twin Birth Study, a total of 1347 (48%) women required a delivery before a spontaneous onset of labor occurred: 568 (42%) in the planned vaginal delivery arm and 779 (58%) in the planned cesarean arm. Induction of labor was attempted in 409 (30%), and 938 (70%) had a pre-labor cesarean section. The rate of intrapartum cesarean section in the induction of labor group was 41.3%. The rate of the primary outcome was comparable between the pre-labor cesarean section group and induction of labor group (1.65% vs. 1.97%; p = 0.61; OR 0.83; 95% CI 0.43–1.62). The maternal composite outcome was found to be lower with pre-labor cesarean section compared to induction of labor (7.25% vs. 11.25%; p = 0.01; OR 0.61; 95% CI 0.41–0.91). Conclusion In women with twin gestation between 320/7–386/7 weeks of gestation, induction of labor and pre-labor cesarean section have similar neonatal outcomes. Pre-labor cesarean section is associated with favorable maternal outcomes which differs from the overall Twin Birth Study results. These data may be used to better counsel women with twin gestation who are faced with the decision of interventional delivery.

Abstract BACKGROUND: We aimed to compare neonatal and maternal outcomes of twin gestations without spontaneous onset of labor, which underwent induction of labor or pre-labor cesarean section.METHODS: In the Twin Birth Study (TBS), women at 320/7-386/7 weeks of gestation, in whom the first twin was in cephalic presentation, were randomized to planned vaginal delivery or cesarean section. In this secondary analysis of the TBS we focused on the outcomes of the subset of women who did not have a spontaneous onset of labor. We compared those who had an induction of labor with those who had a pre-labor cesarean section. The primary outcome was a composite of fetal or neonatal death or serious neonatal morbidity. Secondary outcome was a composite of maternal morbidity and mortality.RESULTS: Of the 2,804 women included in the TBS, a total of 1,347 (48%) women did not have a spontaneous onset of labor: 568 (42%) in the planned vaginal delivery arm and 779 (58%) in the planned cesarean arm. Induction of labor was attempted in 409 (30%), and 938 (70%) had a pre-labor cesarean section. The rate of intrapartum cesarean section in the induction of labor group was 41.3%. The rate of the primary outcome was comparable between the pre-labor cesarean section and induction of labor groups (1.65% vs. 1.97%; p=0.61; OR 0.83; 95% CI 0.43-1.62).

Background: The Systolic Blood Pressure Intervention Trial (SPRINT) randomized patients to a goal SBP <120 mm Hg vs. <140 mm Hg . A subset of patients enrolled in SPRINT MIND, which performed a baseline MRI and measured white matter hyperintensity volume (WMHv). We evaluated the association between WMHv and cardiovascular events. Methods: The primary outcome was a composite of stroke, MI, ACS, decompensated CHF, or CVD death. The secondary outcome was stroke. The WMHv was divided into quartiles. We fit Cox models to the outcomes and report adjusted hazard ratios for the quartiles of WMHv, and stratified by SPRINT treatment arm. Results: Among 719 included patients, the mean WMHv in the quartiles was 0.34, 1.09, 2.61, and 10.8 mL. The primary outcome occurred in 51/719 (7.1%) and the secondary outcome in 10/719 (1.4%). The WMHv was associated with both outcomes (Table 1, Figure 1). After stratifying by treatment arm, we found the association persisted in the standard, but not intensive, treatment arm (Table 2). However, the interaction term between WMHv and treatment arm was not significant. Conclusions: We observed that degree of WMH was associated with CVD and stroke risk in SPRINT MIND. The risk may be attenuated in patients randomized to intensive BP lowering. Trials are needed to determine if intensive BP lowering can prospectively reduce the high cardiovascular risk in patients with WMH.

Objective This study aims to compare melatonin levels in colostrum between vaginal and cesarean delivery. Study Design This cross-sectional study was conducted with 139 mothers who gave live births between February 2016 and December 2016. The mothers were divided into three groups according to the mode of delivery: 60 mothers (43.2%) in the vaginal delivery group, 47 mothers (33.8%) in the elective cesarean delivery, and 32 mothers (23.0%) in the emergency cesarean delivery group. Colostrum of the mothers was taken between 01:00 and 03:00 a.m. within 48 to 72 hours following the delivery, and the melatonin levels were measured using the enzyme-linked immunosorbent assay (ELISA) and compared between the groups. Results The melatonin levels in the colostrum were the highest in the vaginal delivery group, lower in the elective cesarean section group, and the lowest in the emergency cesarean group (265.7 ± 74.3, 204.9 ± 55.6, and 167.1 ± 48.1, respectively; p < 0.001). The melatonin levels in the colostrum did not differ according to the demographic characteristics of the mothers, gestational age, birth weight, newborn sex, the Appearance, Pulse, Grimace, Activity, and Respiration (APGAR) scores, and for the requirement for neonatal intensive care. Conclusion Our study results showed that melatonin levels in the colostrum of the mothers who delivered vaginally were higher than those who delivered by cesarean section. Considering the known benefits of melatonin for the newborns, we believe that vaginal delivery poses an advantage.

Objective The aim of this study was to compare duration of labor induction between diabetic and nondiabetic women receiving dinoprostone vaginal insert (10 mg). Study Design This is a secondary analysis of two large randomized controlled trials using dinoprostone vaginal inserts for labor induction. We compare time to active labor, overall delivery, and vaginal delivery between diabetic and nondiabetic women undergoing induction of labor with a 10-mg dinoprostone vaginal insert. Results Diabetic women receiving dinoprostone vaginal insert had a longer time to onset of active labor, overall delivery, and vaginal delivery than their nondiabetic counterparts. There was no difference in abnormal labor affecting fetal heart rate pattern in diabetic women compared with nondiabetic women. The rates of neonatal hyperbilirubinemia were higher in diabetic women. Conclusion Diabetes may represent an independent factor associated with prolonged induction among women undergoing induction of labor with dinoprostone. Dinoprostone is well tolerated in both diabetic and nondiabetic women. Key Points

Objective: To measure prevalence of discordance between electrical activity recorded by electrocardiography (ECG) and myocardial activity visualized by echocardiography (echo) in patients presenting after cardiac arrest and to compare survival outcomes in cohorts defined by ECG and echo. Methods: This is a secondary analysis of a previously published prospective study at twenty hospitals. Patients presenting after out-of-hospital arrest were included. The cardiac electrical activity was defined by ECG and contemporaneous myocardial activity was defined by bedside echo. Myocardial activity by echo was classified as myocardial asystole- -the absence of myocardial movement, pulseless myocardial activity (PMA)--visible myocardial movement but no pulse, and myocardial fibrillation- -visualized fibrillation. Primary outcome was the prevalence of discordance between electrical activity and myocardial activity. Secondary outcome was survival to hospital discharge. Results: 793 patients and 1943 pauses in CPR were included. 28.6% of CPR pauses demonstrated a difference in electrical activity (ECG) and myocardial activity (echo), 5.0% with asystole (ECG) and PMA (echo), and 22.1% with PEA (ECG) and myocardial asystole (echo). Survival to hospital admission for patients with PMA (echo) was 29.1% (95%CI-23.9-34.9) compared to those with PEA (ECG) (21.4%, 95%CI-17.7-25.6). Twenty-five percent of the 32 pauses in CPR with a shockable rhythm by echo demonstrated a non-shockable rhythm by ECG and were not defibrillated. One of these patients survived, a patient with asystole on ECG and vfib by echo survived because vfib was identified on ECG during a subsequent pause and was defibrillated. Conclusion: Patients in cardiac arrest commonly demonstrate different electrical (ECG) and myocardial activity (echo). Further research is needed to better define cardiac activity during cardiac arrest and to explore outcome between groups defined by electrical and myocardial activity.

Background Maternal race and ethnicity have been identified as significant independent predictors of obstetric morbidity and mortality in the United States. An appreciation of the clinical contexts in which maternal racial and ethnic disparities are most pronounced can better target efforts to alleviate these disparities and improve outcomes. It remains unknown whether cesarean delivery precipitates these divergent outcomes. Objective This study assessed the association between maternal race and ethnicity and cesarean complications. Study Design We conducted a retrospective cohort study from a multicenter observational cohort of women undergoing cesarean delivery. Nulliparous women with non-anomalous singleton gestations who underwent primary cesarean section were included. Race/ethnicity was categorized as non-Hispanic White, non-Hispanic Black, Hispanic, Asian, Native American, or unknown. The primary outcome was a composite of maternal cesarean complications including hysterectomy, uterine atony, blood transfusion, surgical injury, arterial ligation, infection, wound complication, and ileus. A composite of neonatal morbidity was evaluated as a secondary outcome. We created a multivariable logistic regression model adjusting for selected demographic and obstetric variables that may influence the likelihood of the primary outcome. Results A total of 14,570 women in the parent trial met inclusion criteria with an 18.8% incidence of the primary outcome (2,742 women). After adjusting for potential confounding variables, maternal surgical morbidity was found to be significantly higher for non-Hispanic Black (adjusted odds ratios [aORs] 1.96, 95% confidence intervals [CIs] 1.63–2.35) and Hispanic (aOR 1.66, 95% CI 1.37–2.01) women as compared with non-Hispanic white women. Neonatal morbidity was similarly found to be significantly associated with the Black race and Hispanic ethnicity. Conclusion In this cohort, the odds of cesarean-related maternal and neonatal morbidity were significantly higher for non-Hispanic Black and Hispanic women. These findings suggest race as a distinct risk factor for cesarean complications, and efforts to alleviate disparities should highlight cesarean section as an opportunity for improvement in outcomes.
