Objective: To compare rates of adverse pregnancy outcomes in term pregnancies complicated by polyhydramnios between women who had induction of labor (IOB) versus women who had expectant management.

Methods: This multicenter retrospective study included term pregnancies complicated by isolated polyhydramnios. Patients who underwent IOB were compared with those who had expectant management.

Trial of labor after 2 previous cesareans: a multicenter study.

Background: Trial of labor after cesarean after 2 cesarean deliveries is linked to a lower success rate of vaginal delivery and higher rates of adverse obstetrical outcomes than trial of labor after cesarean after 1 previous cesarean delivery.

Objective: This study aimed to investigate the factors associated with failed trial of labor after cesarean among women with 2 previous cesarean deliveries.

Study Design: This was a multicenter retrospective cohort study, which included all women with singleton pregnancies attempting trial of labor after cesarean after 2 previous cesarean deliveries between 2003 and 2021.

The association between discordant umbilical arterial resistance in growth-restricted fetuses and adverse outcomes.

Background: Assessing the umbilical artery pulsatility index via Doppler measurements plays a crucial role in evaluating fetal growth impairment.

Objective: This study aimed to investigate perinatal outcomes associated with discordant pulsatility indices of umbilical arteries in fetuses with growth restriction.

Study Design: In this retrospective cohort study, all singleton pregnancies were included if their estimated fetal weight and/or abdominal circumference fell below the 10th percentile for gestational age (2017-2022).

Evaluating the validity of ChatGPT responses on common obstetric issues: Potential clinical applications and implications.

Objective: To evaluate the quality of ChatGPT responses to common issues in obstetrics and assess its ability to provide reliable responses to pregnant individuals. The study aimed to examine the responses based on expert opinions using predetermined criteria, including "accuracy," "completeness," and "safety."

Methods: We curated 15 common and potentially clinically significant questions that pregnant women are asking.

The association between unintended hysterotomy extensions with cesarean delivery and subsequent preterm birth.

Background: An increased risk for preterm birth has been observed among individuals with a previous second stage cesarean delivery when compared with those with a previous vaginal delivery. One mechanism that may contribute to the increased risk for preterm birth following a second stage cesarean delivery is the increased risk for cervical injury because of extension of the uterine incision (hysterotomy) into the cervix. The contribution of hysterotomy extension to the rate of preterm birth in a subsequent pregnancy has not been investigated and may shed light on the mechanism underlying the observed relationship between the mode of delivery and subsequent preterm birth.

Impacted fetal head extraction methods at second stage cesarean and subsequent preterm delivery: A multicenter study.

Objective: Second-stage cesarean delivery (CD) is associated with subsequent preterm birth (PTB). It has been suggested that an increased risk of PTB after second-stage cesarean delivery could be linked to a higher chance of cervical injury due to the extension of the uterine incision. Previous studies have shown that reverse breech extraction is associated with lower rates of uterine incision extensions compared to the "push" method.

Is a pregnancy following a second trimester uterine evacuation associated with increased adverse maternal and neonatal outcomes?

Objective: To evaluate maternal and neonatal outcomes of pregnancies following a uterine evacuation in the second trimester, in comparison to a first trimester spontaneous pregnancy loss.

Study Design: A retrospective analysis of data of women who conceived ≤6 months following a uterine evacuation due to a spontaneous pregnancy loss and subsequently delivered in a single tertiary medical center between 2016 and 2021. Maternal and neonatal outcomes were compared between women with second trimester (14-23 weeks) and first trimester (<14 weeks) pregnancy loss.

The Correlation between Fetal Monitor Decelerations Area and Neonatal Cord pH among Preeclamptic parturient: an Automated Approach to a Clinical Challenge.

Objective: To examine whether a correlation exists between electronic fetal monitoring (EFM) in the final 120 minute prior to delivery and neonatal cord blood pH among parturients with preeclampsia.

Study Design: A retrospective cohort study of parturients with term and near-term preeclampsia who delivered at Soroka University Medical Center between 2013 and 2020 was conducted. EFM tracings, demographical data, and obstetrical outcomes were retrieved from the patients' electronic medical records.

Trial of labor following cesarean in patients with bicornuate uterus: a multicenter retrospective study.

Objective: This study aimed to evaluate whether a trial of labor after cesarean delivery (TOLAC) in women with a bicornuate uterus is associated with increased maternal and neonatal morbidity compared to women with a non-malformed uterus.

Methods: A multicenter retrospective cohort study was conducted at two university-affiliated centers between 2005 and 2021. Parturients with a bicornuate uterus who attempted TOLAC following a single low-segment transverse cesarean delivery (CD) were included and compared to those with a non-malformed uterus.

The aim of this multicenter retrospective cohort study was to examine the impact of maternal age on perinatal outcomes in multiparas, stratified according to maternal age in one- and two-year increments. The analysis involved 302,484 multiparas who delivered between the years 2003 and 2021 in four university-affiliated obstetrics departments. Maternal age was considered both as a continuous variable and in two-year intervals, as compared with a comparison group of parturients aged 25-30 years.

Impact of prior use of topical hemostatic agents on trial of labor after cesarean: Insights from a multicenter cohort study.

Objective: To evaluate the association between a topical hemostatic agent used at the time of cesarean delivery and uterine scar disruption (rupture or dehiscence) at the subsequent trial of labor after cesarean (TOLAC).

Methods: A multicenter retrospective cohort study was conducted (2005-2021). Parturients with a singleton pregnancy in whom a topical hemostatic agent was placed during the primary cesarean delivery were compared with patients in whom no such agent was placed.

Operative delivery in the second stage of labor and preterm birth in a subsequent pregnancy: a systematic review and meta-analysis.

Objective: This study aimed to quantify the association between mode of operative delivery in the second stage of labor (cesarean delivery vs operative vaginal delivery) and spontaneous preterm birth in a subsequent pregnancy.

Data Sources: MEDLINE, Embase, EmCare, CINAHL, the Cochrane Library, Web of Science: Core Collection, and Scopus were searched from database inception to April 1, 2023.

Study Eligibility Criteria: All retrospective cohort studies with participants who had a second-stage cesarean delivery (defined as intrapartum cesarean delivery at full cervical dilation) or operative vaginal delivery (including forceps- and/or vacuum-assisted delivery) and that reported the rate of preterm birth (either spontaneous or not specified) in subsequent pregnancy were included.

Failed vacuum and preterm delivery risk in the subsequent pregnancy: a multicenter retrospective cohort study.

Background: Second-stage cesarean delivery is associated with subsequent preterm delivery. Failed vacuum-assisted delivery is a subgroup of second-stage cesarean delivery in which the fetal head is engaged deeper in the pelvis and, thus, is associated with an increased risk of short-term maternal complications.

Objective: This study aimed to investigate the maternal and neonatal outcomes of women at their subsequent delivery after a second-stage cesarean delivery with failed vacuum-assisted extraction vs after a second-stage cesarean delivery without a trial of vacuum-assisted extraction.
