Induction of labor in late-term pregnancy: amniotomy plus early oxytocin perfusion versus amniotomy plus oxytocin perfusion delayed by 24 h.

Objective: To assess the maternal and fetal benefits of delaying oxytocin perfusion by 24 h following labor induction by amniotomy after 41 weeks of gestation (WG).

Methods: We performed a retrospective review including all women with a vertex presentation fetus who had an indication for labor induction by amniotomy with or without oxytocin after 41 WG between 2015 and 2022. Patients who underwent an IOL by amniotomy followed by oxytocin perfusion within 0 to 4 hours (early oxytocin group: EO group) were compared with patients who underwent an IOL by amniotomy alone or followed by an oxytocin perfusion after an expectant period for up to 24 hours in the absence of a spontaneous onset of labor (delayed oxytocin group: DO group).

Ultrasound Plane Pose Regression: Assessing Generalized Pose Coordinates in the Fetal Brain.

In obstetric ultrasound (US) scanning, the learner's ability to mentally build a three-dimensional (3D) map of the fetus from a two-dimensional (2D) US image represents a significant challenge in skill acquisition. We aim to build a US plane localization system for 3D visualization, training, and guidance without integrating additional sensors. This work builds on top of our previous work, which predicts the six-dimensional (6D) pose of arbitrarily oriented US planes slicing the fetal brain with respect to a normalized reference frame using a convolutional neural network (CNN) regression network.

Simulation training for pelvic examination: A systematic review.

Objective: Pelvic examination including vaginal digital examination and speculum inspection are crucial medical skills that are challenging to teach for both professors and students, because of its intimate nature. Consequently, education has shifted from a traditional approach to a simulation-enhanced education. This literature review summarizes the level of evidence for these not-so-new training modalities.

Retrospective evaluation of labor induction with scar uterus at the university hospital of Rennes.

Objective: The aim of the study was a retrospective evaluation of labor induction in women with one previous cesarean section. The primary outcome was the mode of delivery. We also studied the severe maternal and neonatal morbidity and identify some prediction factors of vaginal delivery after labor induction after one previous cesarean section.

Physical environment of the operating room during cesarean section: A systematic review.

Introduction: Environmental factors in the operating room during cesarean sections are likely important for both women/birthing people and their babies but there is currently a lack of rigorous literature about their evaluation. The principal aim of this study was to systematically examine studies published on the physical environment in the obstetrical operating room during c-sections and its impact on mother and neonate outcomes. The secondary objective was to identify the sensors used to investigate the operating room environment during cesarean sections.

[Simulation training for French obstetrics and gynecology residents: A national survey in 2022].

Objectives: To evaluate the use of simulation among French Obstetrics and Gynecology residency programs.

Methods: A survey was conducted with all 28 French residency program directors. The questionnaire covered equipment and human resources, training programs, types of simulation tools and time spent.

Trial of labor versus elective cesarean delivery for patients with two prior cesarean-sections: A retrospective propensity score analysis.

Introduction: Despite awareness of obstetricians to the constant increase in the number of cesarean sections in recent years, the fear of a uterine scar rupture is still present and influences the choice of the mode of delivery in patients with two previous cesarean sections. However, several clinical studies have suggested that, under certain conditions, vaginal birth after two cesarean sections is usually successful and safe.

Objective: The objective of this study was to compare maternal and neonatal issues according to the planned mode of delivery in patients with two previous cesarean sections.

Role of chromosomal imbalances in the pathogenesis of DSD: A retrospective analysis of 115 prenatal samples.

Differences of sex development (DSDs) are a group of congenital conditions characterized by a discrepancy between chromosomal, gonadal, and genital sex development of an individual, with significant impact on medical, psychological and reproductive life. The genetic heterogeneity of DSDs complicates the diagnosis and almost half of the patients remains undiagnosed. In this context, chromosomal imbalances in syndromic DSD patients may help to identify new genes implicated in DSDs.

Assessment of compliance with a color code protocol for non-elective cesarean section and its impact on time to delivery interval and neonatal outcomes.

Introduction: We set out to assess the compliance with a cesarean section color code protocol and its impact on maternal and neonatal outcomes since its implementation in our maternity ward.

Methods: This was a retrospective study including a sample of 200 patients per year who underwent a non-elective cesarean section delivery in Rennes University Hospital from January 1, 2015 to December 31, 2018. Patients were grouped by year and by color code (red, orange or green).

Predictive value of head-perineum distance measured at the initiation of the active second stage of labor on the mode of delivery: A prospective cohort study.

Objective: The objective was to assess the predictive value of head-perineum distance measured at the initiation of the active second stage of labor on the mode of delivery.

Material And Methods: It was a prospective cohort study in an academic Hospital of Rennes, France, from July 1, 2020 to April 4, 2021 including 286 full-term parturients who gave birth to a newborn in cephalic presentation. A double-blind ultrasound measurement of the head-perineum distance was performed during the second phase of labor within five minutes after the onset of pushing efforts.

Tranexamic Acid for the Prevention of Blood Loss after Cesarean Delivery.

Background: Prophylactic administration of tranexamic acid has been associated with reduced postpartum blood loss after cesarean delivery in several small trials, but evidence of its benefit in this clinical context remains inconclusive.

Methods: In a multicenter, double-blind, randomized, controlled trial, we assigned women undergoing cesarean delivery before or during labor at 34 or more gestational weeks to receive an intravenously administered prophylactic uterotonic agent and either tranexamic acid (1 g) or placebo. The primary outcome was postpartum hemorrhage, defined as a calculated estimated blood loss greater than 1000 ml or receipt of a red-cell transfusion within 2 days after delivery.

Single bilateral ovarian venous return in uterine transplant: Validation in an orthotopic auto-transplant model in the Yucatan minipig.

Background: Uterine transplant (UT) represents an opportunity to treat absolute uterine infertility. However, the use of uterine veins for venous return, in addition to ovarian veins, significantly increases the risk of ureteral wounds in the living donor and UT time for the recipient. Our aim was to demonstrate that dual ovarian venous return is sufficient for graft viability and survival.

Metrics used to evaluate obstetric ultrasound skills on simulators: A systematic review.

Obstetric ultrasound simulators are now used for training and evaluating OB/GYN students but there is a lack of literature about evaluation metrics in this setting. In this literature review, we searched MEDLINE and the COCHRANE database using the keywords: (Obstetric OR Fetal) AND (Sonography OR Ultrasound) AND Simulation. Of a total of 263 studies screened, we selected nine articles from the title and the abstract in PubMed, in the past 5 years.

Performance of diagnostic ultrasound to identify causes of hydramnios.

Introduction: We aimed to assess the diagnostic yield of ultrasonography in the identification of the etiology of hydramnios, and the added value of MRI or amniocentesis.

Methods: We conducted a single-center retrospective study including pregnancies with confirmed hydramnios (defined as deepest pocket ≥8 cm) between January 2013 and May 2017. Twin pregnancies, secondary hydramnios discovered after the diagnosis of a causal pathology, and pregnancies of unknown outcome were excluded.

Endocrine disruptors and pregnancy: Knowledge, attitudes and practice of perinatal health professionals. A French multicentre survey.

Introduction: Endocrine disruptors (ED) such as phthalates or bisphenol A are ubiquitous and pregnant women and children are particularly vulnerable. Perinatal health professionals are well-placed to inform pregnant women about the risks. We set out to evaluate perinatal health professionals' knowledge of ED and the information they give during pregnancy.
