Introduction: Synthetic oxytocin is one of the most regularly administered medications to facilitate labor induction and augmentation. The present study examined the associations between oxytocin administration during childbirth and postpartum posttraumatic stress symptoms (PTSS).

Materials And Methods: In a multicenter longitudinal study, women completed questionnaires during pregnancy and at 2 months postpartum ( N = 386).

Secundiparas following a failed vacuum delivery-factors associated with a successful vaginal delivery: a historical prospective cohort.

Background: Few studies have focused on the delivery subsequent to a failed vacuum delivery (failed-VD) in secundiparas. The objective of the current study was to examine the factors associated with a vaginal delivery following a failed-VD.

Methods: An historical prospective cohort.

Parity-Adjusted Term Neonatal Growth Chart Modifies Neonatal Morbidity and Mortality Risk Stratification.

Objective: To investigate the impact of parity-customized versus population-based birth weight charts on the identification of neonatal risk for adverse outcomes in small (SGA) or large for gestational age (LGA) infants compared to appropriate for gestational age (AGA) infants. Study design: Observational, retrospective, cohort study based on electronic medical birth records at a single center between 2006 and 2017. Neonates were categorized by birth weight (BW) as SGA, LGA, or AGA, with the 10th and 90th centiles as boundaries for AGA in a standard population-based model adjusted for gestational age and gender only (POP) and a customized model adjusted for gestational age, gender, and parity (CUST).

Extended fertility at highly advanced reproductive age is not related to anti-Müllerian hormone concentrations.

Research Question: Is extended fertility at the advanced reproductive age of 43-47 years associated with high anti-Müllerian hormone (AMH) concentrations?

Design: Prospective cohort study including 98 women aged 43-47 years old with a spontaneous conception who were tested for AMH concentrations 1-4 days and 3-11 months post-partum. AMH concentrations at 3-11 months post-partum were further compared with AMH concentrations in healthy age-matched controls that last gave birth at ≤42 years old. Women with current use of combined hormonal contraceptives (CHC), ovarian insult or polycystic ovary syndrome were excluded.

Sonographic growth curves versus neonatal birthweight growth curves for the identification of fetal growth restriction.

Objective: Fetal growth restriction is suspected when the estimated fetal weight is <10th percentile for gestational age. Using a regional sonographic estimated fetal weight growth curve to diagnose fetal growth restriction has no known benefits; however, the traditional approach of using birthweight curves is misleading, since a large proportion of preterm births arise from pathological pregnancies. Our aim was to compare the diagnostic accuracies of sonographic versus birthweight curves in diagnosing fetal growth restriction.

Maternal and Neonatal Outcomes Following Trial of Labor After Two Previous Cesareans: a Retrospective Cohort Study.

The objective of this study is to evaluate the maternal and neonatal outcomes of parturients attempting trial of labor (TOL) after two previous CD versus those who had an elective third repeat CD. A retrospective computerized database cohort study was conducted at a single tertiary center between 2005 and 2019. Various maternal and neonatal outcomes were compared between parturients attempting TOL after two CD versus parturients opting for elective third repeat CD.

Induction of labor at second delivery subsequent to a primary cesarean: is stage of labor at previous cesarean a factor?

Purpose: Parturients with a history of a cesarean delivery (CD) in the first delivery (P1), undergoing induction of labor (IOL) in the subsequent delivery (P2) are at increased risk for obstetric complications. The primary aim was to study if "the stage of labor" at previous cesarean (elective/latent/first/second) is associated with a successful IOL. The secondary aim was to search for other obstetric characteristics associated with a successful IOL.

The use of a strict protocol in the trial of labor following two previous cesarean deliveries: Maternal and neonatal results.

Objective: Over the past few decades, the rate of repeat cesarean deliveries (CD) have taken on pandemic proportions. As part of the global effort to reduce the rate of CD, trail of labor (TOL) following one and even two previous CDs is encouraged. We aimed to evaluate maternal and neonatal outcomes of parturients attempting a TOL after two previous CDs, in which a strict departmental protocol was adopted.

Trial of labor after cesarean delivery in grand multiparous women: maternal and neonatal outcomes.

Objective: To evaluate success rates of vaginal birth after cesarean (VBAC) and maternal and neonatal outcomes associated with trial of labor after cesarean in grand multiparous women.

Study Design: A retrospective computerized data base study was conducted at a single tertiary center, between 2005 and 2019. The study compared the maternal and neonatal outcomes of trial of labor after cesarean delivery in grand multiparous women (parity ≥ 6) as compared to multiparous women (parity: 3-5).

Duration of first vaginal birth following cesarean: Is stage of labor at previous cesarean a factor?

Objective: Parturients in second delivery undergoing vaginal birth after cesarean (VBAC) are divided to those who had their cesarean delivery (CD) while in labor as opposed to those who had an elective CD. We aimed to study if the stage of labor that was present during the primary CD is associated with the duration of subsequent spontaneous VBAC.

Methods: A retrospective study (2006-2014).

The use of absorbable adhesion barriers to reduce the incidence of intraperitoneal adhesions at repeat cesarean delivery.

Purpose: We aimed to evaluate the effect of an absorbable adhesion barrier (oxidized regenerated cellulose) for the prevention of peritoneal adhesions in women undergoing repeat cesarean delivery (CD).

Methods: This is a retrospective, single center study that included all women who underwent two consecutive CDs, 2011-2018. Women in whom an absorbable adhesion barrier (oxidized regenerated cellulose) was placed at the time of the initial CD (index CD) were compared to women in whom no such barrier was placed.

Isolated neonatal clavicular fracture is a risk factor for future shoulder dystocia.

Objective: Shoulder dystocia (SD) is a risk factor for neonatal clavicular fracture (CF). Previous SD is a known risk factor for subsequent SD. It is unknown whether an isolated neonatal CF (one that is not associated with SD) increases the risk of future SD.

Fertility intentions and the way they change following birth- a prospective longitudinal study.

Background: Women's fertility intentions, their desired number of children and desired inter-pregnancy interval (IPI) are related to micro (personal) and macro (socio-cultural) level factors. We investigated factors that contribute to changes in women's fertility intentions in Israel, a developed country with high birth rates.

Methods: Pregnant women (N = 1163), recruited from prenatal clinics and hospitals in two major metropolitan areas, completed self-report questionnaires prenatally (≥24 weeks gestation) and postpartum (2 months after childbirth).

Women's preferences for mode of second birth-A prospective study of two Israeli birth cohorts.

Introduction: Various biopsychosocial factors affect women's preferences with respect to mode of birth, but they are usually not examined simultaneously and prospectively. In the current study, we assessed the contribution of personal characteristics of first-time mothers, their prior prenatal perceptions, events during birth, and subjective birth experiences, on their preference about mode of second birth.

Methods: This was a secondary analysis of two prospective birth cohort studies.

A decade's experience in primipara, term, singleton, vertex parturients with a sustained low rate of CD.

Background Cesarean delivery (CD) in primiparas with a term singleton vertex fetus (PTSV) is a sentinel event for the future mode of delivery and determinant of repeat CD risk. We aimed to evaluate the risk factors for primary CD in a population with a decade of sustained low rate of intrapartum CD. Methods This was a retrospective single-center cohort study between 2005 and 2014.

Screening for gestational diabetes mellitus - Can we use the 50-g glucose challenge test of the previous pregnancy?

Aim: To assess the association between previous pregnancy glucose challenge test (GCT) result among non-diabetic women and the rate for gestational diabetes mellitus (GDM) in the subsequentpregnancy.

Methods: Retrospective database study in a university affiliated medical center from 2005 to 2017. Women who had a singleton pregnancy and two consecutive deliveries in our medical center were included.

To drain or not to drain: intraperitoneal closed-suction drainage placement during cesarean delivery.

Introduction: Intraperitoneal closed suction drains are occasionally placed during cesarean delivery. This study aims to ascertain the prevalence, associated factors, outcome, and risks of intraperitoneal closed-suction drain placed during cesarean delivery.

Material And Methods: A retrospective cohort study of all women undergoing cesarean delivery in a single center from 2005 to 2015.

Maternal and neonatal outcomes following a proactive peripartum multidisciplinary management protocol for placenta creta spectrum as compared to the urgent delivery.

Background: Adherent and invasive placenta, termed Placenta Creta Spectrum (PCS), is associated with increased maternal morbidity and mortality. Incidence and risk factors for Placenta Creta are on the rise and call to optimize the obstetric care for this condition.

Objectives: We sought to compare maternal and neonatal outcomes between a ProActive Peripartum Multidisciplinary Approach (PAMA) as compared to the urgent management of the Placenta Creta Spectrum patients.

Delayed diagnosis of intrapartum uterine rupture - maternal and neonatal consequences.

To assess the maternal and neonatal outcomes following delayed diagnosis of uterine rupture (diagnosis during the early postpartum period) in comparison to women with an intrapartum diagnosis of uterine rupture. Retrospective study of electronic medical records (EMR) from 2005 to 2018 in a single large academic tertiary care. Demographic, obstetric and maternal characteristics and outcomes were retrieved and compared.

Risk factors, early and late postpartum complications of retained placenta: A case control study.

Objectives: To identify risk factors and complications associated with 3 stage of labor removal of placental fragments (3 SRPF) by manual uterine revision under a strict protocol.

Study Design: Ten years retrospective register-based cohort study of vaginal deliveries. Women with 3 SRPF n = 3297 (exposed) and those without n = 97,888 (non exposed) were compared.

Assessment of maternal GBS colonization and early-onset neonatal disease rate for term deliveries: a decade perspective.

Objective To assess the maternal group B streptococcal (GBS) colonization rate and neonatal early-onset GBS (EOGBS) disease in term deliveries, a decade apart. Methods This was a retrospective computerized study between 2005 and 2016. A universal GBS culture-based approach gradually replaced the GBS risk-oriented screening.

The recurrence risk of group B Streptococcus in consecutive deliveries.

Group B streptococcus (GBS) is a significant cause of neonatal morbidity and mortality. GBS maternal colonization status was found to be transient, intermittent, or chronic and screening during each subsequent pregnancy was advised. Recent studies showed that GBS colonization rate was higher among women with history of GBS positive in prior pregnancy.

The impact of epidural analgesia on the mode of delivery in nulliparous women that attain the second stage of labor.

We aimed to evaluate the impact of epidural analgesia on the mode of delivery of nulliparous women with a term single fetus in vertex presentation (NTSV) that attained the second stage of labor. A single-center retrospective study provided a strict and constant department protocol for epidural analgesia practice and obstetric interventions, between 2005 and 2014. Epidural users were compared to nonusers.
