Objective: This study aimed to ascertain the outcomes associated with a cervical cerclage among individuals with a history of previable prelabor rupture of membranes (PROM)., Study Design: This study was a retrospective cohort study conducted at a single tertiary center between 2011 and 2021. We included individuals with a history of previable (before 24 weeks) PROM and the subsequent viable pregnancy. Women with multifetal gestation, preterm birth (PTB) or cerclage in previous gestation, or abdominal cerclage after trachelectomy were excluded. Primary outcome was PTB rate (delivery <37 weeks). Recurrence of preterm PROM and adverse composite maternal and neonatal outcomes (CMO and CNO) were evaluated as secondary outcomes. CMO included any of the following: suspected chorioamnionitis, endometritis, red blood cell transfusion, uterine rupture, unplanned hysterectomy, or death. CNO included any of the following: previable PTB (<24 weeks of gestation), bronchopulmonary dysplasia, grade 3 or 4 intraventricular hemorrhage, necrotizing enterocolitis, mechanical ventilation, seizures, hypoxic ischemic encephalopathy, or death., Results: During the study period, 118 individuals had a history of previable PROM and a documented subsequent pregnancy, out of which 74 (62.7%) met inclusion criteria. Nineteen (25.7%) of eligible individuals underwent a cerclage for prior previable PROM and were compared with controls ( n  = 55, 74.3%). Women who underwent a cerclage had higher rates of PTB < 37 weeks (63.2 vs. 10.9%, p  < 0.001; odds ratio [OR]: 14.00, 95% confidence interval [CI]: 3.97-49.35) and < 34 weeks (21.1 vs. 3.6%, p  = 0.03; OR: 7.07, 95% CI: 1.18-42.39) compared with those without cerclage. Furthermore, recurrent preterm PROM and previable PTB rates were higher among patients who underwent cerclage. The survival curve further indicated that individuals with cerclage delivered earlier. CMO and CNO rates were similar in those with and without cerclage., Conclusion: Cerclage placement in individuals with prior previable PROM was associated with higher rates of recurrent preterm PROM and PTB., Key Points: · The management of individuals in a subsequent pregnancy following previable PROM is a conundrum.. · Cerclage following previable PROM is associated with higher rates of recurrent preterm PROM and PTB.. · Composite maternal and neonatal outcome rates were similar in those with and without cerclage.., Competing Interests: None declared., (Thieme.

Objective: This study aimed to evaluate whether the suspension of intrapartum maternal oxygen supplementation for nonreassuring fetal heart rate is associated with adverse perinatal outcomes., Study Design: A retrospective cohort study, including all individuals that underwent labor in a single tertiary medical center. On April 16, 2020, the routine use of intrapartum oxygen for category II and III fetal heart rate tracings was suspended. The study group included individuals with singleton pregnancies that underwent labor during the 7 months between April 16, 2020, and November 14, 2020. The control group included individuals that underwent labor during the 7 months before April 16, 2020. Exclusion criteria included elective cesarean section, multifetal pregnancy, fetal death, and maternal oxygen saturation <95% during delivery. The primary outcome was defined as the rate of composite neonatal outcome, consisting of arterial cord pH <7.1, mechanical ventilation, respiratory distress syndrome, necrotizing enterocolitis, intraventricular hemorrhage grade 3/4, and neonatal death. The secondary outcome was the rate of cesarean and operative delivery., Results: The study group included 4,932 individuals, compared with 4,906 individuals in the control group. The suspension of intrapartum oxygen treatment was associated with a significant increase in the rate of composite neonatal outcome (187 [3.8%] vs. 120 [2.4%], p  < 0.001), including the rate of abnormal cord arterial pH <7.1 (119 [2.4%] vs. 56 [1.1%], p  < 0.01). A higher rate of cesarean section due to nonreassuring fetal heart rate was noted in the study group (320 [6.5%] vs. 268 [5.5%], p  = 0.03).A logistic regression analysis revealed that the suspension of intrapartum oxygen treatment was independently associated with the composite neonatal outcome (adjusted odds ratio = 1.55 [95% confidence interval, 1.23-1.96]) while adjusting for suspected chorioamnionitis, intrauterine growth restriction, and recent coronavirus disease 2019 exposure., Conclusion: Suspension of intrapartum oxygen treatment for nonreassuring fetal heart rate was associated with higher rates of adverse neonatal outcomes and urgent cesarean section due to fetal heart rate., Key Points: · The available data on intrapartum maternal oxygen supplementation are equivocal.. · Suspension of maternal oxygen for nonreassuring fetal heart rate during labor was associated with adverse neonatal outcomes.. · Oxygen treatment might still be important and relevant during labor.., Competing Interests: None declared., (Thieme.

Objective: The aim of this study was to compare the pregnancy outcome of two different management strategies: outpatient versus inpatient in women with prenatal diagnosis of vasa previa., Materials and Methods: This is a retrospective cohort study conducted at a single tertiary center. Women with a prenatally diagnosed vasa previa between January 2007 and June 2017 were included. Obstetric and neonatal outcomes were compared between two management strategies: elective admission at 34 weeks of gestation or outpatient management unless there were signs of labor or premature contractions., Results: A total of 109 women met the inclusion criteria: 75 (68.8%) women in the inpatient group and 34 (31.2%) in the outpatient group. Women in the inpatient group were more likely to receive antenatal steroids (57.3 vs. 26.4%, p  = 0.002) and were less likely to have an urgent cesarean section (34.6 vs. 58.8%, respectively, p  < 0.001) compared with outpatient group. There was no difference in the rate of neonatal complications (inpatient: 64.6% vs. outpatient: 52.7%, p  = 0.27) or neonatal anemia requiring transfusion (2.7 vs. 5.8%, respectively, p  = 0.5) between the groups., Conclusion: The rate of elective cesarean section and exposure to antenatal steroids was higher in patients with vasa previa who were admitted electively at 34 weeks of gestation compared with patients who were managed as outpatient., Competing Interests: None., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)
