Idiopathic polyhydramnios and postnatal outcomes of children: The role of exome sequencing. Prenat Diagn 2024. [PMID: 38682787 DOI: 10.1002/pd.6573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 03/29/2024] [Accepted: 04/01/2024] [Indexed: 05/01/2024]
Abstract
OBJECTIVES The objective of our study was to evaluate the long-term outcome of children born from a pregnancy complicated by idiopathic polyhydramnios. The secondary objective was to investigate factors associated with adverse outcomes. METHODS We conducted a retrospective study in two prenatal diagnosis centers between January 1, 2009 and December 31, 2020. Inclusion criteria were pregnancies with a diagnosis of idiopathic polyhydramnios, defined by a deepest pocket greater than 8 cm, no detectable abnormality at ultrasound and a negative amniotic fluid assessment including karyotype, chromosomal microarray, biochemical assays (electrolytes and digestive enzymes), and viruses (parvovirus B19 and cytomegalovirus). One-year outcomes of these children were collected. The primary endpoint was adverse postnatal outcome, defined by at least one of the following criteria: stillbirth, neonatal death, or serious and incurable condition diagnosed in the first year of life. RESULTS Of the 245 women referred for isolated polyhydramnios, 73 were diagnosed with idiopathic polyhydramnios after prenatal investigations. The mean age at follow-up of children was 28 months (95% CI 20-36). An adverse outcome occurred in 25% of cases (18/73), with one stillbirth, two neonatal deaths, and 15 severe conditions diagnosed postnatally, including a rate of monogenic disorders of 8.2% (6/73). Pediatric follow-up was normal for 75% of the children (55/73), including a rate of 9% (5/55) of curable conditions. Repeated amnioreduction was independently associated with an adverse outcome. CONCLUSION Pregnant women with polyhydramnios should be informed of the increased risk of 25% of perinatal mortality and serious conditions diagnosed after birth.

The role of pre- and postnatal investigations in suspected isolated hypospadias. J Gynecol Obstet Hum Reprod 2024; 53:102781. [PMID: 38561025 DOI: 10.1016/j.jogoh.2024.102781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 03/25/2024] [Accepted: 03/25/2024] [Indexed: 04/04/2024]
Abstract
INTRODUCTION Prenatal investigations are usually performed to diagnose severe or associated forms of hypospadias. However, the value of this workup and the correlation with the postnatal diagnosis and follow-up have not been studied in the literature. The aims of the study were to describe postnatal outcomes. MATERIAL AND METHODS We conducted a single-center retrospective study. We included fetuses with a prenatal suspicion of isolated hypospadias (no associated ultrasound abnormality). Postnatal findings were described including neonatal examination with confirmation of the diagnosis or not of hypospadias, the diagnosis of isolated or associated hypospadias, investigations and management. RESULTS A total of 21 patients with a suspicion of isolated hypospadias on prenatal ultrasound and available postnatal follow-up were included. The diagnosis of hypospadias was confirmed at neonatal examination for 17/21 (81 %) children. All 17 confirmed cases underwent at least one urological surgical procedure. Postnatally, the diagnosis of hypospadias in 4/17(23.5 %) cases was found to be associated with the following diagnosis: Denys-Drash syndrome, deletion of chromosome9 and duplication of chromosome20 involved in genital development, significant duplication of the short arm of chromosome 16, mosaic karyotypic abnormality [45, X (64 %)/46, XY (36 %)]. The hormonal assessment revealed 3/17(17.6 %) abnormalities: one diagnosis of partial androgen insensitivity syndrome and two cases of gonadal dysgenesis with low AMH and inhibin B. CONCLUSION Prenatal diagnosis of isolated hypospadias may be associated with postnatal genetic abnormalities. In this context, a prenatal assessment by amniocentesis with chromosomal microarray analysis can be an option after discussion with the woman.

Prevalence and risk factors for postpartum depression 2 months after a vaginal delivery: a prospective multicenter study. Am J Obstet Gynecol 2024; 230:S1128-S1137.6. [PMID: 38193879 DOI: 10.1016/j.ajog.2023.08.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 08/25/2023] [Accepted: 08/25/2023] [Indexed: 01/10/2024]
Abstract
BACKGROUND Very little is known about the prevalence and risk factors of postpartum depression among women with vaginal births without major pregnancy complications. OBJECTIVE This study aimed to assess the prevalence of postpartum depression and identify its characteristics 2 months after singleton vaginal delivery at or near term. STUDY DESIGN This was an ancillary cohort study of the TRanexamic Acid for Preventing Postpartum Hemorrhage After Vaginal Delivery randomized controlled trial, which was conducted in 15 French hospitals in 2015-2016 and enrolled women with singleton vaginal deliveries after 35 weeks of gestation. After randomization, the characteristics of labor, delivery, and the immediate postpartum experience, including the experience of childbirth, were prospectively collected. Medical records provided women's other characteristics, particularly any psychiatric history. Of note, 2 months after childbirth, provisional postpartum depression diagnosis was defined as a score of ≥13 on the Edinburgh Postnatal Depression Scale, a validated self-administered questionnaire. The corrected prevalence of postpartum depression was calculated with the inverse probability weighting method to take nonrespondents into account. Associations between potential risk factors and postpartum depression were analyzed by multivariate logistic regression. Moreover, an Edinburgh Postnatal Depression Scale cutoff value of ≥11 was selected to perform a sensitivity analysis. RESULTS The questionnaire was returned by 2811 of 3891 women (72.2% response rate). The prevalence rates of the provisional diagnosis were 9.9% (95% confidence interval, 8.6%-11.3%) defined by an Edinburgh Postnatal Depression Scale score of ≥13 and 15.5% (95% confidence interval, 14.0%-17.1%) with a cutoff value of ≥11. The characteristics associated with higher risks of postpartum depression in multivariate analysis were mostly related to prepregnancy characteristics, specifically age of <25 years (adjusted odds ratio, 1.8; 95% confidence interval, 1.1-2.9) and advanced age (adjusted odds ratio, 1.8; 95% confidence interval, 1.2-2.6), migration from North Africa (adjusted odds ratio, 2.9; 95% confidence interval, 1.9-4.4), previous abortion (adjusted odds ratio, 1.4; 95% confidence interval, 1.0-2.0), and psychiatric history (adjusted odds ratio, 2.9; 95% confidence interval, 1.8-4.8). Some characteristics of labor and delivery, such as induced labor (adjusted odds ratio, 1.5; 95% confidence interval, 1.1-2.0) and operative vaginal delivery (adjusted odds ratio, 1.4; 95% confidence interval, 1.0-2.0), seemed to be associated with postpartum depression. In addition, bad memories of childbirth in the immediate postpartum were strongly associated with postpartum depression symptoms at 2 months after giving birth (adjusted odds ratio, 2.4; 95% confidence interval, 1.3-4.2). CONCLUSION Approximately 10% of women with vaginal deliveries have postpartum depression symptoms, assessed by a score of ≥13 on the depression scale that was used at 2 months. Prepregnancy vulnerability factors; obstetrical characteristics, such as induced labor and operative vaginal delivery; and bad memories of childbirth 2 days after delivery were the main factors associated with this provisional diagnosis. A screening approach that targets risk factors may help to identify women at risk of postpartum depression who could benefit from early intervention.

Uterine-sparing surgical procedures to control postpartum hemorrhage. Am J Obstet Gynecol 2024; 230:S1066-S1075.e4. [PMID: 37729440 DOI: 10.1016/j.ajog.2022.06.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Revised: 06/05/2022] [Accepted: 06/12/2022] [Indexed: 09/22/2023]
Abstract
Postpartum hemorrhage remains one of the principal causes of maternal mortality in the United States and throughout the world. Its management, which must be multidisciplinary (obstetrics, midwifery, anesthesiology, interventional radiology, and nursing), depends on the speed of both diagnosis and implementation of medical and surgical treatment to control the hemorrhage. The aim of this work is to describe the various techniques of vessel ligation and of uterine compression for controlling and treating severe hemorrhage, and to present the advantages and disadvantages of each. It is not difficult to perform vessel ligation of the uterine arteries: O'Leary's bilateral ligation of the uterine artery, Tsirulnikov's triple ligation, and AbdRabbo's stepwise uterine devascularization (that is, stepwise triple ligation). These procedures are associated with a high success rate (approximately 90%) and a low complication rate. Bilateral ligation of the internal iliac (hypogastric) arteries is more difficult to perform and potentially less effective (approximately 70% effectiveness) than the previously mentioned procedures. Its complication rate is low, but the complications are most often serious. There is no evidence that future fertility or subsequent obstetrical outcomes are impaired by ligation of either the uterine or internal iliac arteries. There are many techniques used for uterine compression sutures, and none has shown clear superiority to another. Uterine compression suture has an effectiveness rate of approximately 75% after failure of medical treatment and approximately 80% as a second-line procedure after unsuccessful vessel ligation. The risk of synechiae after uterine compression suture has not yet been adequately evaluated, but is probably around 5%. The risk of synechiae after uterine compression suture has not yet been adequately evaluated, but probably ranges between 5% and 10%. The methodologic quality of the studies assessing uterine-sparing surgical procedures remains limited, with no comparative studies. Accordingly, no evidence suggests that any one of these methods is better than any other. Accordingly, the choice of surgical technique to control hemorrhage must be guided firstly by the operator's experience. If the hemorrhage continues after a first-line uterine-sparing surgical procedure and the patient remains hemodynamically stable, a second-line procedure can be chosen. Nonetheless, the application of these procedures must not delay the performance of a peripartum hysterectomy in cases of hemodynamic instability.

Closed- or open-glottis pushing for vaginal delivery: a planned secondary analysis of the TRAnexamic Acid for Preventing postpartum hemorrhage after vaginal delivery study. Am J Obstet Gynecol 2024; 230:S879-S889.e4. [PMID: 37633725 DOI: 10.1016/j.ajog.2023.07.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Accepted: 07/11/2023] [Indexed: 08/28/2023]
Abstract
BACKGROUND The effect on obstetrical outcomes of closed- or open-glottis pushing is uncertain among both nulliparous and parous women. OBJECTIVE This study aimed to assess the association between open- or closed-glottis pushing and mode of delivery after an attempted singleton vaginal birth at or near term. STUDY DESIGN This was an ancillary planned cohort study of the TRAAP (TRAnexamic Acid for Preventing postpartum hemorrhage after vaginal delivery) randomized controlled trial, conducted in 15 French maternity units from 2015 to 2016 that enrolled women with an attempted singleton vaginal delivery after 35 weeks' gestation. After randomization, characteristics of labor and delivery were prospectively collected, with special attention to active second-stage pushing and a specific planned questionnaire completed immediately after birth by the attending care provider. The exposure was the mode of pushing, classified into 2 groups: closed- or open-glottis. The main endpoint was operative vaginal delivery. Secondary endpoints were items of maternal morbidity, including severe perineal laceration, episiotomy, postpartum hemorrhage, duration of the second stage of labor, and a composite severe neonatal morbidity outcome. We also assessed immediate maternal satisfaction, experience of delivery, and psychological status 2 months after delivery. The associations between mode of pushing and outcome were analyzed by multivariate logistic regression to control for confounding bias, with multilevel mixed-effects analysis, and a random intercept for center. RESULTS Among 3041 women included in our main analysis, 2463 (81.0%) used closed-glottis pushing and 578 (19.0%) open-glottis pushing; their respective operative vaginal delivery rates were 19.1% (n=471; 95% confidence interval, 17.6-20.7) and 12.5% (n=72; 95% confidence interval, 9.9-15.4; P<.001). In an analysis stratified according to parity and after controlling for available confounders, the rate of operative vaginal delivery did not differ between the groups among nulliparous women: 28.7% (n=399) for the closed-glottis and 27.5% (n=64) for the open-glottis group (adjusted odds ratio, 0.93; 95% confidence interval, 0.65-1.33; P=.7). The operative vaginal delivery rate was significantly lower for women using open- compared with closed-glottis pushing in the parous population: 2.3% (n=8) for the open- and 6.7% (n=72) for the closed-glottis groups (adjusted odds ratio, 0.43; 95% confidence interval, 0.19-0.90; P=.03). Other maternal and neonatal outcomes did not differ between the 2 modes of pushing among either the nulliparous or parous groups. CONCLUSION Among nulliparous women with singleton pregnancies at term, the risk of operative vaginal birth did not differ according to mode of pushing. These results will inform shared decision-making about the mode of pushing during the second stage of labor.

The ethics of induction of labor at 39 weeks in low-risk nulliparas in research and clinical practice. Am J Obstet Gynecol 2024; 230:S775-S782. [PMID: 37633577 DOI: 10.1016/j.ajog.2023.07.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 07/18/2023] [Accepted: 07/23/2023] [Indexed: 08/28/2023]
Abstract
The "A Randomized Trial of Induction Versus Expectant Management" trial (ARRIVE trial) published in 2018 suggested that induction of labor can be considered a "reasonable option" for low-risk nulliparous women at ≥39 weeks of gestation. The study results led some professional societies to endorse the option for elective induction of labor at 39 weeks of gestation in low-risk nulliparas, and this has begun to change obstetrical practice. The ARRIVE trial provided valuable information supporting the benefits of induction of labor; however, the trial is insufficient to serve as the primary justification for widespread elective induction of labor at 39 weeks of gestation in low-risk nulliparas because of concerns about external validity. Thus, the French ARRIVE trial was designed to test the hypothesis in a different setting that elective induction of labor at 39 weeks of gestation in low-risk nulliparas leads to a lower cesarean delivery rate than expectant management. This ongoing trial has been criticized as "pseudoscientific" and telling "women where, when, and how to give birth." We reject these allegations and extensively examine the ethical framework that should govern clinical and research interventions, including elective induction of labor at 39 weeks of gestation in low-risk nulliparas. This study aimed to discuss the ethical issues that emerge from randomized trials of elective induction of labor at 39 weeks of gestation in low-risk nulliparas and the ethics of the clinical practice itself. The analysis of existing evidence shows the importance of further research on induction of labor at 39 weeks of gestation in low-risk women. Certain aspects of research ethics in this area, particularly the consent of pregnant women in a context where autonomy remains fragile, call for vigilance. In addition, we emphasize that childbirth is not only a medical object but also a social phenomenon that cannot be regarded only from the perspective of a health risk to be managed by clinical research. Further research on this issue is needed to allow pregnant women to make informed decisions, and the results should be integrated with social issues. The perspective of women is required in constructing, evaluating, and implementing medical interventions in childbirth, such as induction of labor at 39 weeks of gestation.

Abstract
OBJECTIVE To identify strategies for reducing neonatal and maternal morbidity associated with intrahepatic cholestasis pregnancy (ICP). MATERIAL AND METHODS The quality of evidence of the literature was assessed following the GRADE methodology with questions formulated in the PICO format (Patients, Intervention, Comparison, Outcome) and outcomes defined a priori and classified according to their importance. An extensive bibliographic search was performed on PubMed, Cochrane, EMBASE and Google Scholar databases. The quality of the evidence was assessed (high, moderate, low, very low) and a (i) strong or (ii) weak recommendations or (iii) no recommendation were formulated. The recommendations were reviewed in two rounds with external reviewers (Delphi survey) to select the consensus recommendations. RESULTS Of the 14 questions (from 12 PICO questions and one definition question outside the PICO format), there was agreement between the working group and the external reviewers on 14 (100%). The level of evidence of the literature was insufficient to provide a recommendation on two questions. ICP is defined by the occurrence of suggestive pruritus (palmoplantar, nocturnal) associated with a total bile acid level>10μmol/L or an alanine transaminase level above 2N after ruling out differential diagnoses. In the absence of suggestive symptoms of a differential diagnosis, it is recommended not to carry out additional biological or ultrasound tests. In women with CIP, ursodeoxycholic acid is recommended to reduce the intensity of maternal pruritus (Strong recommendation. Quality of the evidence moderate) and to decrease the level of total bile acids and alanine transaminases. (Strong recommendation. Quality of the evidence moderate). S-adenosyl-methionine, dexamethasone, guar gum or activated charcoal should not be used to reduce the intensity of maternal pruritus (Strong recommendation. Quality of evidence low), and there is insufficient data to recommend the use of antihistamines (No recommendation. Quality of evidence low). Rifampicin (Weak recommendation. Very low quality of evidence) or plasma exchange (Strong recommendation. Very low quality of evidence) should not be used to reduce maternal pruritus and perinatal morbidity. Serum monitoring of bile acids is recommended to reduce perinatal morbidity and mortality (stillbirth, prematurity) (Low recommendation. Quality of the evidence low). The level of evidence is insufficient to determine whether fetal heart rate or fetal ultrasound monitoring are useful to reduce perinatal morbidity (No recommendation). Birth is recommended when bile acid level is above 99μmol/L from 36 weeks gestation to reduce perinatal morbidity, in particular stillbirth. When bile acid level is above 99μmol/L is below 100μmol/L, women should be informed that induction of labor could be considered 37 and 39 weeks gestation to reduce perinatal morbidity. (Strong recommendation. Quality of evidence low). In postpartum, total bile acids and alanine transaminases level should be checked and normalized before prescribing estrogen-progestin contraception, ideally with a low estrogen dose (risk of recurrence of pruritus and cytolysis) (Low recommendation. Quality of evidence very low). CONCLUSION Although the quality of evidence regarding ICP gestational cholestasis remains low, there is a strong consensus in France, as shown by our Delphi study, on how to manage women with ICP. The reference first-line treatment is ursodeoxycholic acid.

Abstract
OBJECTIVES The management for isolated increased nuchal translucency (NT) in the first trimester with a normal karyotype and normal Chromosomal Microarray Analysis (CMA) is not consensual. The aim was to perform a survey among the Pluridisciplinary Centers for Prenatal Diagnosis (CPDPN) in France regarding their management of increased NT in the first trimester. METHODS We conducted a multicenter descriptive survey between September 2021 and October 2021 among the 46 CPDPNs of France. RESULTS The response rate was 56.5% (n = 26/46). The NT thickness threshold for which invasive diagnosis testing is performed is 3.0mm in 23.1% of centers (n = 6/26) and 3.5mm in 76.9% of centers (n = 20/26). A CMA was performed alone in 26.9% of centers (n = 7/26) while 7.7% of centers (n = 2/26) did not perform a CMA. The gestational age for the first reference ultrasound scan was 16 to 18 WG in 88.5% of centers (n = 23/26), while it was not performed before 22 WG in 11.5% of centers (n = 3/26). Fetal echocardiography is proposed systematically in 73.1% of centers (n = 19/26). CONCLUSION There is heterogeneity in the management of increased NT in the first trimester among the CPDPNs in France. In case of increased NT on first trimester ultrasound scan, the NT thickness threshold for which invasive diagnosis testing is performed varies from 3.0 mm or 3.5mm depending on the center. Moreover, CMA and early reference morphological ultrasound scan between 16 and 18 WG were not systematically performed, despite the current data suggesting their interest.

Abstract
Importance The stereotype that men perform surgery better than women is ancient. Surgeons have long been mainly men, but in recent decades an inversion has begun; the number of women surgeons is increasing, especially in obstetrics and gynecology. Studies outside obstetrics suggest that postoperative morbidity and mortality may be lower after surgery by women. Objective To evaluate the association between surgeons' gender and the risks of maternal morbidity and postpartum hemorrhage (PPH) after cesarean deliveries. Design, Setting, and Participants This prospective cohort study was based on data from the Tranexamic Acid for Preventing Postpartum Hemorrhage after Cesarean Delivery (TRAAP2) trial, a multicenter, randomized, placebo-controlled trial that took place from March 2018 through January 2020 (23 months). It aimed to investigate whether the administration of tranexamic acid plus a prophylactic uterotonic agent decreased PPH incidence after cesarean delivery compared with a uterotonic agent alone. Women having a cesarean delivery before or during labor at or after 34 weeks' gestation were recruited from 27 French maternity hospitals. Exposures Self-reported gender (man or woman), assessed by a questionnaire immediately after delivery. Main Outcomes and Measures The primary end point was the incidence of a composite maternal morbidity variable, and the secondary end point was the incidence of PPH (the primary outcome of the TRAAP2 trial), defined by a calculated estimated blood loss exceeding 1000 mL or transfusion by day 2. Results Among 4244 women included, men surgeons performed 943 cesarean deliveries (22.2%) and women surgeons performed 3301 (77.8%). The rate of attending obstetricians was higher among men (441 of 929 [47.5%]) than women (687 of 3239 [21.2%]). The risk of maternal morbidity did not differ for men and women surgeons: 119 of 837 (14.2%) vs 476 of 2928 (16.3%) (adjusted risk ratio, 0.92 [95% CI, 0.77-1.13]). Interaction between surgeon gender and level of experience on the risk of maternal morbidity was not statistically significant. Similarly, the groups did not differ for PPH risk (adjusted risk ratio, 0.98 [95% CI, 0.85-1.13]). Conclusions and Relevance Risks of postoperative maternal morbidity and of PPH exceeding 1000 mL or requiring transfusion by day 2 did not differ by the surgeon's gender.

Predictors of shoulder dystocia at the time of operative vaginal delivery: a prospective cohort study. Sci Rep 2023; 13:2658.

Abstract
Our aim was to identify factors associated with shoulder dystocia following an attempted operative vaginal delivery (aOVD) in a prospective cohort study and to evaluate whether these factors can be used to accurately predict shoulder dystocia by building a score of shoulder dystocia risk. This was a planned secondary analysis of a prospective cohort study of deliveries with aOVD at term from 2008-2013. Cases were defined as women with shoulder dystocia following an aOVD defined as a delivery that requires additional obstetric maneuvers following failure of gentle downward traction on the fetal head to effect delivery of the shoulders. Multivariate logistic regression analyses were performed to determine risk factors for shoulder dystocia. Shoulder dystocia occurred in 57 (2.7%) of the 2118 women included. In the whole cohort, women with shoulder dystocia more often had a history of shoulder dystocia (3.5% vs. 0.2%, p = 0.01), and there was a significant interaction between aOVD and gestational age and the duration of the second stage of labor: women with shoulder dystocia more often had a gestational age > 40 weeks and a second stage of labor longer than 3 h specifically for midpelvic aOVD. In multivariable analysis, a history of shoulder dystocia was the only factor independently associated with shoulder dystocia following aOVD (aOR 27.00, 95% CI 4.10-178.00). The AUC for the receiver operating characteristic curve generated using a multivariate model with term interaction with head station was 0.70 (95% CI 0.62-0.77). The model failed to accurately predict shoulder dystocia.

Abstract
OBJECTIVE To identify procedures to reduce maternal morbidity during cesarean. MATERIAL AND METHODS The quality of evidence of the literature was assessed following the GRADE® method with questions formulated in the PICO format (Patients, Intervention, Comparison, Outcome) and outcomes defined a priori and classified according to their importance. An extensive bibliographic search was performed on PubMed, Cochrane and EMBASE databases. The quality of the evidence was assessed (high, moderate, low, very low) and a (i) strong or (ii) weak recommendations or (iii) no recommendation were formulated. The recommendations were reviewed in two rounds with external reviewers (Delphi survey) to select the consensus recommendations. RESULTS Of the 27 questions, there was agreement between the working group and the external reviewers on 26. The level of evidence of the literature was insufficient to provide a recommendation on 15 questions. Preventing hypothermia is recommended to increase maternal satisfaction and comfort (weak recommendation) and to reduce neonatal hypothermia (strong recommendation). The quality of the evidence of the literature did not allow to recommend the skin disinfectant to be used nor the relevance of a preoperative vaginal disinfection nor the choice between the use or nonuse of an indwelling bladder catheterization (if micturition takes place 1 hour before the cesarean section). The Misgav-Ladach technique or its analogues should be considered rather than the Pfannenstiel technique to reduce maternal morbidity (weak recommendation) bladder flap before uterine incision should not be performed routinely (weak recommendation), but a blunt (weak recommendation) and cephalad-caudad extension of uterine incision (weak recommendation) should be considered to reduce maternal morbidity. Antibiotic prophylaxis is recommended to reduce maternal infectious morbidity (strong recommendation) without recommendation on its type or the timing of administration (before incision or after cord clamping). The administration of carbetocin after cord clamping does not significantly decrease the incidence of blood loss>1000 ml, anemia, or blood transfusion compared with the administration of oxytocin. Thus, it is not recommended to use carbetocin rather than oxytocin in cesarean. It is recommended that systematic manual removal of the placenta not to be performed (weak recommendation). An antiemetic should be administered after cord clamping in women having a planned cesarean under locoregional anaesthesia to reduce intraoperative and postoperative nausea and vomiting (strong recommendation) with no recommendation regarding choice of use one or two antiemetics. The level of evidence of the literature was insufficient to provide any recommendation concerning single or double-layer closure of the uterine incision, or the uterine exteriorization. Closing the peritoneum (visceral or parietal) should not be considered (weak recommendation). The quality of the evidence of the literature was not sufficient to provide recommendation on systematic subcutaneous closure, including in obese or overweight patients, or the use of subcuticular suture in obese or overweight patients. The use of subcuticular suture in comparison with skin closure by staples was not considered as a recommendation due to the absence of a consensus in the external review rounds. CONCLUSION In case of cesarean, preventing hypothermia, administering antiemetic and antibiotic prophylaxis after cord clamping are the only strong recommendations. The Misgav-Ladach technique, the way of performing uterine incision (no systematic bladder flap, blunt cephalad-caudad extension), not performing routine manual removal of the placenta nor closure of the peritoneum are weak recommendations and may reduce maternal morbidity.

Tranexamic acid for the prevention of blood loss after cesarean among women with twins: a secondary analysis of the TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery randomized clinical trial. Am J Obstet Gynecol 2022; 227:889.e1-889.e17. [PMID: 35724759 DOI: 10.1016/j.ajog.2022.06.019] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Revised: 06/05/2022] [Accepted: 06/08/2022] [Indexed: 01/27/2023]
Abstract
BACKGROUND Although prophylactic tranexamic acid administration after cesarean delivery resulted in a lower incidence of calculated estimated blood loss of >1000 mL or red cell transfusion by day 2, its failure to reduce the incidence of hemorrhage-related secondary clinical outcomes (TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery trial) makes its use questionable. The magnitude of its effect may differ in women at higher risk of blood loss, including those with multiple pregnancies. OBJECTIVE This study aimed to compare the effect of tranexamic acid vs placebo to prevent blood loss after cesarean delivery among women with multiple pregnancies. STUDY DESIGN This was a secondary analysis of the TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery trial data, a double-blind, randomized controlled trial from March 2018 to January 2020 in 27 French maternity hospitals, that included 319 women with multiple pregnancies. Women with a cesarean delivery before or during labor at ≥34 weeks of gestation were randomized to receive intravenously 1 g of tranexamic acid (n=160) or placebo (n=159), both with prophylactic uterotonics. The primary outcome was a calculated estimated blood loss of >1000 mL or a red blood cell transfusion by 2 days after delivery. The secondary outcomes included clinical and laboratory blood loss measurements. RESULTS Of the 4551 women randomized in this trial, 319 had a multiple pregnancy and cesarean delivery, and 298 (93.4%) had primary outcome data available. This outcome occurred in 62 of 147 women (42.2%) in the tranexamic acid group and 67 of 152 (44.1%) receiving placebo (adjusted risk ratio, 0.97; 95% confidence interval, 0.68-1.38; P=.86). No significant between-group differences occurred for any hemorrhage-related clinical outcomes: gravimetrically estimated blood loss, provider-assessed clinically significant hemorrhage, additional uterotonics, postpartum blood transfusion, arterial embolization, and emergency surgery (P>.05 for all comparisons). CONCLUSION Among women with a multiple pregnancy and cesarean delivery, prophylactic tranexamic acid did not reduce the incidence of any blood loss-related outcomes.

Arabin pessary to prevent adverse perinatal outcomes in twin pregnancies with a short cervix: a multicenter randomized controlled trial (PESSARONE). Am J Obstet Gynecol 2022; 227:271.e1-271.e13. [PMID: 35123930 DOI: 10.1016/j.ajog.2022.01.038] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2021] [Revised: 01/17/2022] [Accepted: 01/28/2022] [Indexed: 11/01/2022]
Abstract
BACKGROUND The number of twin pregnancies continues to increase worldwide as both the number of pregnancies obtained by medically assisted reproduction and age at first pregnancy keep rising. Preterm delivery is the major complication associated with twin pregnancies. The effectiveness of preventive treatments such as progesterone or cervical cerclage for women with a short cervix is doubtful in twin pregnancies. The effectivity of cervical pessaries in preventing preterm birth and its associated morbidity and mortality is also controversial. OBJECTIVE We sought to investigate if the Arabin pessary reduces adverse neonatal outcomes in twin pregnancies with a short cervix. STUDY DESIGN This open-label, multicenter, randomized controlled trial on twin pregnancies with a cervical length of <35 mm compared pessary placement at 16+0 to 24+0 weeks' gestation with standard care alone. The primary endpoint was a composite of adverse neonatal outcomes, namely peripartum or neonatal death or significant neonatal morbidity before hospital discharge, defined as at least 1 of the following complications: bronchopulmonary dysplasia, intraventricular hemorrhage grade III to IV, periventricular leukomalacia, necrotizing enterocolitis grade II or higher, culture-proven sepsis, and retinopathy requiring treatment. A sample size of 308 pregnancies was planned to ensure 80% power to compare the proportions of women with at least 1 infant with an adverse neonatal outcome. The intention-to-treat analysis after multiple imputation of missing data, was supplemented with a secondary analysis that controlled for gestational age and cervical length, both at inclusion. The primary endpoint was also compared between randomization groups in the per-protocol population, which excluded patients with prespecified major protocol violations (mostly cervical cerclage and/or progesterone after inclusion). Secondary endpoints included preterm birth, spontaneous preterm birth, and pessary side effects. RESULTS In total, 315 women were randomized to either receive a pessary (n=157) or standard management (n=158). Overall, 10.8% (34 women) of participants had a missing value for the primary endpoint, mostly (79%) because of the lack of paternal consent for neonatal data collection. In the intention-to-treat analysis, the adverse neonatal outcome occurred in 16.8% of the pessary group vs in 22.5% of the control group (risk ratio, 0.69; 95% confidence interval, 0.39-1.23; P=.210). The per-protocol analysis did not show any significant difference between groups (risk ratio, 0.78; 95% confidence interval, 0.47-1.28; P=.320). The occurrence of preterm birth or spontaneous preterm birth did not differ significantly between groups. No serious side effects were associated with pessary use. CONCLUSION Pessary use in our study did not significantly reduce adverse neonatal outcomes in twin pregnancies with a short cervix.

Should prenatal chromosomal microarray analysis be offered for isolated fetal growth restriction? A French multicenter study. Am J Obstet Gynecol 2021; 225:676.e1-676.e15.

Abstract
BACKGROUND Compared with standard karyotype, chromosomal microarray analysis improves the detection of genetic anomalies and is thus recommended in many prenatal indications. However, evidence is still lacking on the clinical utility of chromosomal microarray analysis in cases of isolated fetal growth restriction. OBJECTIVE This study aimed to estimate the proportion of copy number variants detected by chromosomal microarray analysis and the incremental yield of chromosomal microarray analysis compared with karyotype in the detection of genetic abnormalities in fetuses with isolated fetal growth restriction. STUDY DESIGN This retrospective study included all singleton fetuses diagnosed with fetal growth restriction and no structural ultrasound anomalies and referred to 13 French fetal medicine centers over 1 year in 2016. Fetal growth restriction was defined as an estimated fetal weight of <tenth percentile for gestational age identified in ultrasound reports. For this analysis, we selected fetuses who underwent invasive genetic testing with karyotype and chromosomal microarray analysis results. Data were obtained from medical records and ultrasound databases and postmortem and placental examination reports in case of spontaneous stillbirths and terminations of pregnancy. Following the American College of Medical Genetics and Genomics guidelines, copy number variants were classified into 5 groups as following: pathogenic, likely pathogenic, variant of unknown significance, likely benign, and benign. RESULTS Of 682 referred fetuses diagnosed with isolated fetal growth restriction, both karyotype and chromosomal microarray analysis were performed in 146 fetuses. Overall, the detection rate of genetic anomalies found by chromosomal microarray analysis was estimated to be 7.5% (11 of 146 [95% confidence interval, 3.3-11.8]), including 10 copy number variants classified as pathogenic and 1 copy number variant classified as likely pathogenic. Among the 139 fetuses with normal karyotype, 5 were detected with pathogenic and likely pathogenic copy number variants, resulting in an incremental yield of 3.6% (95% confidence interval, 0.5-6.6) in chromosomal microarray analysis compared with karyotype. All fetuses detected with pathogenic or likely pathogenic copy number variants resulted in terminations of pregnancy. In addition, 3 fetuses with normal karyotype were detected with a variant of unknown significance (2.1%). Among the 7 fetuses with abnormal karyotype, chromosomal microarray analysis did not detect trisomy 18 mosaicism in all fetuses. CONCLUSION Our study found that compared with karyotype, chromosomal microarray analysis improves the detection of genetic anomalies in fetuses diagnosed with isolated fetal growth restriction. These results support the use of chromosomal microarray analysis in addition to karyotype for isolated fetal growth restriction.

Chronic histiocytic intervillositis: manifestation of placental alloantibody-mediated rejection. Am J Obstet Gynecol 2021; 225:662.e1-662.e11.

Abstract
BACKGROUND Chronic histiocytic intervillositis (chronic intervillositis) is defined by a diffuse infiltration of monocytes into the intervillous space, which often leads to poor obstetrical outcomes, including recurrent intrauterine growth restriction, miscarriage, and fetal death. The pathogenesis of chronic intervillositis is still poorly defined, and there is an unmet medical need for improved management. OBJECTIVE This study aimed to demonstrate the role of anti-human leukocyte antigen alloantibodies in the pathogenesis of chronic intervillositis through the application of criteria used in solid-organ transplantation for the diagnosis of antibody-mediated rejection. STUDY DESIGN A multidisciplinary research study based on thorough immunologic and pathologic investigations was carried out for 2 separate couples who experienced recurrent secondary fetal losses following a first normal pregnancy associated with histologic evidence of chronic intervillositis. RESULTS Very high levels of complement-fixing, fetus-specific antibodies targeting mismatched human leukocyte antigen alleles, harbored by the 2 paternal haplotypes, were identified in both cases. Polymorphic human leukocyte antigens were expressed on the surface of trophoblastic villi of the inflamed placenta but not in healthy placental tissue. The binding of alloantibodies to paternal human leukocyte antigens induced dramatic activation of the complement classical pathway in trophoblastic villi, leading to C4d deposition and formation of the terminal complex C5b-9. All requirements for the diagnosis of antibody-mediated placental rejection were fulfilled according to the criteria used in the Banff classification of allograft pathology. In silico analysis was performed using a human leukocyte antigen epitope viewer to reconstitute the human leukocyte antigen sensitization history. Reactivity against a single mismatched epitope present in the first-born healthy child accounted for a broad sensitization to human leukocyte antigens, including those harbored by the 2 paternal haplotypes. This finding explained the high rates of chronic intervillositis recurrence during subsequent pregnancies. CONCLUSION This study provides novel mechanistic insights into the pathogenesis of chronic intervillositis and provides new avenues for individualized counseling and therapeutic options.

Abstract
INTRODUCTION In Doppler flow diagnosis of a large placental chorioangioma with vascularization, there may be fetal consequences as cardiac output failure and polyhydramnios. Prenatal percutaneous fetoscopic laser photocoagulation of chorioangioma is a therapeutic option. First, we present 2 cases of chorioangioma treated by fetoscopic laser photocoagulation. Second, we conducted a narrative review to identify all reported cases of chorioangioma treated by fetoscopic laser photocoagulation. CASE PRESENTATION Case 1 presented a chorioangioma measuring 48 × 36 × 42 mm, and the Doppler flow study showed vascularization with a high flow rate. The fetus showed dilatation of the right cardiac chambers, moderate tricuspid insufficiency, normal Doppler indices, and polyhydramnios. Case 2 presented a chorioangioma measuring 58 × 36 × 31 mm associated with polyhydramnios and elevated peak systolic velocity of the middle cerebral artery at 49 cm/s, that is, 1.65 MoM. The procedure was performed at 22+2 and 23+5 WG for both cases. Photocoagulation of the chorioangioma vessels was performed first on the small superficial vessels (capillaries) and then on the feeding vessels (artery first and then vein), until complete cessation of blood flow on ultrasound. Successful devascularization was achieved when flow within the chorioangioma's feeding vessels was no longer visualized on intraoperative ultrasound examination using Doppler flow. The ultrasound follow-up showed complete cessation of blood flow in the chorioangioma, normalization of fetal signs, and normal fetal growth in both cases. In case 1, a 2,350-g boy was delivered vaginally after spontaneous labor at 33+6 WG. In case 2, a 2,700-g boy was delivered vaginally after spontaneous labor at 39+2 WG. Neonatal findings were normal, and the outcome at 1 year was normal for both children. CONCLUSION Prenatal percutaneous fetoscopic laser photocoagulation improves survival in large chorioangioma, despite a risk of fetal death in utero.

Optimal gestational age at delivery in isolated left-sided congenital diaphragmatic hernia. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2021; 57:968-973. [PMID: 32610372 DOI: 10.1002/uog.22133] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Revised: 04/25/2020] [Accepted: 06/18/2020] [Indexed: 06/11/2023]
Abstract
OBJECTIVE To evaluate the morbidity and mortality of neonates with left-sided isolated congenital diaphragmatic hernia (CDH) according to gestational age at delivery. METHODS This was a retrospective study of fetuses diagnosed prenatally with isolated left-sided CDH that were delivered in the University Hospitals of Antoine Béclère-Bicêtre and Leuven between 1 January 2010 and 31 December 2018. The Kaplan-Meier method was used to calculate cumulative survival at 28 days after birth according to gestational age at delivery. The association between gestational age at delivery, as a continuous variable, and survival at 28 days was modeled using a fractional polynomial. Adjustment for position of the liver, management center and mode of delivery was performed. The association was also evaluated according to the severity of CDH, as defined by the observed-to-expected lung-to-head ratio (o/e-LHR), which was classified as severe (o/e-LHR < 25%), moderate (o/e-LHR between 25% and 45%) or mild (o/e-LHR > 45%). RESULTS We included 213 fetuses with isolated left-sided CDH, with a median gestational age at delivery of 38 + 2 weeks (interquartile range, 37 + 0 to 39 + 1 weeks). The survival rates at 28 days and at 6 months were 66.7% (142/213) and 64.3% (137/213), respectively. Kaplan-Meier analysis showed a higher survival rate at 28 days for babies delivered between 37 + 0 and 38 + 6 weeks than for those delivered at or after 39 + 0 weeks (log-rank test, P < 0.001). In the subgroup of moderate CDH, the 28-day survival rate was significantly higher in newborns delivered between 37 + 0 and 38 + 6 weeks than in those delivered at or after 39 + 0 weeks (81.5% vs 61.5%; P = 0.03), and this was also the case for survival rate at 6 months. In the subgroup with moderate CDH, 28-day survival significantly increased with advancing gestational age at birth up to about 38-39 weeks (P = 0.005), and significantly decreased from 39 weeks onwards. CONCLUSION Delivery between 37 + 0 and 38 + 6 weeks' gestation is associated with a higher survival rate at 28 days in neonates with isolated left-sided CDH and moderate lung hypoplasia, independently of intrathoracic liver, management center and mode of delivery. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
We present a rare documented case with consecutive hypo- and hyperthyroidism during fetal life. First, hypothyroidism was due to transplacental passage of antithyroid drugs. After the mother's thyroidectomy, fetal hyperthyroidism was due to transplacental passage of persistent anti-thyrotropin receptor antibodies. Fetal goiter disappeared after adjusting maternal treatment.

Hypoglycemia and Glycemic Control With Glyburide in Women With Gestational Diabetes and Genetic Variants of Cytochrome P450 2C9 and/or OATP1B3. Clin Pharmacol Ther 2021; 110:141-148.

Abstract
Glyburide is mainly metabolized by the cytochrome P450 2C9 (CYP2C9) enzyme and enters the liver via the transporter OATP1B3. The variants OATP1B3*4 (699 G>A; rs7311358) and CYP2C9*2 and *3 are known to have a significant influence on the hepatic uptake and metabolism of glyburide, with lower clearance than in the wild type. In an ancillary study of the INDAO trial, we selected 117 pregnant women with gestational diabetes treated by glyburide and assessed the role of the combined CYP2C9 and OATP1B3 genetic polymorphisms in hypoglycemia and glycemic control. Three groups were constituted: (1) the wild-type genotype group (wild-type allele genotype for both CYP2C9*1 and OATP1B3*1 (699G)), (2) the intermediate group (carriers of CYP2C9*2 allele or OATP1B3*4 (699G>A) heterozygous), and (3) the variant group (carriers of CYP2C9*3 allele and/or OATP1B3*4 (699G>A) homozygous variant). We found that the risk of hypoglycemia was significantly higher in the variant genotype at the second week of treatment: 20.0% (4/20) vs. 8.1% (3/37) in the intermediate group and 4.1% (2/49) in the wild-type genotype group (P = 0.03). The last daily dose of glyburide during pregnancy was lower for patients in the variant genotype group: 4.7 mg (SD 3.5) vs. 8.7 mg (SD 5.7) in the wild-type group and 5.7 mg (SD 3.7) in the intermediate group (P < 0.01). In conclusion, the no-function variants CYP2C9*3 and OATP1B3*4 are associated with a higher risk of hypoglycemia and a lower dose of glyburide in women with gestational diabetes treated with glyburide, which is consistent with the pharmacokinetic roles of both CYP2C9 and OATP1B3.

Abstract
First trimester ultrasound screening is an essential fetal examination performed generally at 11-13 weeks of gestation (WG). However, it does not allow for an accurate description of all fetal organs, partly due to their development in progress. Meanwhile, increased nuchal translucency (INT) is a widely used marker known to be associated with chromosomal deleterious rearrangements. We report on a 14 WG fetus with an association of INT and univentricular congenital heart malformation (CHM) leading to chorionic villous sampling (CVS). Cytogenetic investigations performed using array-Comparative Genomic Hybridization (CGH) and fluorescence in situ hybridization (FISH) demonstrated a 1.17 Mb deletion in 16q24.1 encompassing FOXF1 arisen de novo on maternal inherited chromosome. Fetopathological study confirmed CHM with hypoplastic left heart syndrome (HLHS) associating aortic atresia, mitral stenosis, and left ventricular hypoplasia and revealed in addition specific lung lesions corresponding to alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV). This is so far the first case of first trimester prenatal diagnosis of ACDMPV due to the deletion of FOXF1 gene. An interpretation of the complex genomic data generated by ultrasound markers is facilitated considerably by the genotype-phenotype correlations on fetopathological examination.

[PMID: 33401273 DOI: 10.1159/000510823] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2020] [Accepted: 08/11/2020] [Indexed: 11/19/2022]
Abstract
OBJECTIVE The objective of this study is to assess the effectiveness and safety of intrafetal vascular laser ablation (VLA) for fetuses with bronchopulmonary sequestration (BPS) with hydrops. METHODS First, we present 3 cases of fetuses with BPS and hydrops treated by VLA. Second, we aimed to conduct a narrative review to identify all reported cases of fetuses with BPS treated by intrafetal VLA. RESULTS The review of the literature identified 41 fetuses treated by VLA for BPS with hydrops. The median gestational age of the VLA was 27+0 weeks' gestation [25+0-31+0] with an associated procedure at the same time in 43% of the cases (pleuroamniotic shunt, thoracentesis, and amniodrainage). A second procedure was required in 25% of cases for residual flow in the feeding vessel. No stillbirth or neonatal death was reported. The complications reported were a fetal thoracic hematoma complicated by fetal anemia and 4 preterm deliveries with a rate of 9%. CONCLUSION VLA of the feeding vessel can be an effective treatment but is not without complications. In cases demonstrating cardiac output failure, intrafetal VLA should be considered as a treatment for BPS.

Glyburide therapy for gestational diabetes: Glycaemic control, maternal hypoglycaemia, and treatment failure. DIABETES & METABOLISM 2020; 47:101210. [PMID: 33249198 DOI: 10.1016/j.diabet.2020.11.002] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 11/14/2020] [Accepted: 11/15/2020] [Indexed: 10/22/2022]
Abstract
AIMS The recommended first-line treatment for women with gestational diabetes mellitus (GDM) in the case of failure of diet is insulin. Recent results suggest that there is a potential role for glyburide therapy and highlight the need for better knowledge of glycaemic control with glyburide. The objective of this study was to describe and quantify in women with GDM the quality of glycaemic control, including the risk of maternal hypoglycaemia and of therapy failure. METHODS This is a secondary analysis of the French INDAO non-inferiority trial from 2012 to 2016, in which 890 women with GDM randomized to receive glyburide or insulin treatment were compared for perinatal outcomes. Blood glucose concentrations were assessed prospectively during pregnancy. Optimal glycaemic control was defined as less than 20% of blood glucose values exceeding the targets. RESULTS More than 50% of the women had optimal glycaemic control with glyburide, similar to that with insulin. Around 40% of the women had at least one episode of hypoglycaemia, more than with insulin. However, those hypoglycaemic episodes were mostly moderate and the rate of severe hypoglycaemia decreased significantly during the course of the trial. Failure of glyburide treatment (switch to insulin therapy) occurred in 18% of women and had few predictors. However, when failure occurred, glycaemic control was improved after switching to insulin. CONCLUSIONS Glyburide is an effective treatment for reaching glycaemic goals during pregnancy in women with GDM. The risk of maternal hypoglycaemia may be minimized by clinical practice experience. These findings could be taken into account in the management of GDM.

Does socioeconomic status have any influence on success at the national ranking exam?, a prospective survey. BMC MEDICAL EDUCATION 2020; 20:402. [PMID: 33138812 PMCID: PMC7607746 DOI: 10.1186/s12909-020-02321-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Accepted: 10/21/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND The weight of social inequalities during education is a reality. Students of lower socioeconomic status may have less chance of success in higher education, particularly in medical studies. However, the role of students' socioeconomic factors, such as their parents' profession, in their success in the national ranking exam (NRE) has not been studied. Our aim was to investigate the association between socioeconomic factors and success in the national ranking exam among sixth year medical students at the Paris-Sud Faculty of Medicine. METHODS This was a prospective survey of all sixth-year medical students at the Paris-Sud Faculty of Medicine, using a questionnaire on socioeconomic factors, which were compared according to NRE rank. RESULTS Of 172 sixth year medical students, 110 completed the questionnaire. Their ranking ranged from 20 to 7695, with a median of 2815 (interquartile range: 1029-4581). The factors associated with the NRE rank were a high school diploma (baccalauréat) A or B grade, success at the first attempt in the first-year medical examination, and enrollment in the NRE preparatory lectures during the sixth year of medical training (linear regression, p < 0.001). The educational status and socio-professional category of the parents were not associated with the NRE rank (linear regression, p = 0.92). CONCLUSION At the Paris-Sud Faculty of Medicine, there was no association between parental socioeconomic status and sixth year students' success in the NRE.

Abstract
OBJECTIVE To determine the management of patients with term prelabor rupture of membranes. METHODS Synthesis of the literature from the PubMed and Cochrane databases and the recommendations of French and foreign societies and colleges. RESULTS Term prelabor rupture of membranes is considered a physiological process until 12 h have passed since rupture (professional consensus). In cases of expectant management and with a low rate of antibiotic prophylaxis, home care may be associated with an increase in neonatal infections (LE3), compared with hospitalization, especially for women with group B streptococcus (GBS) colonization (LE3). Home care is therefore not recommended (grade C). In the absence of spontaneous labor within 12 h of rupture, antibiotic prophylaxis may reduce the risk of maternal intrauterine infection but not of neonatal infection (LE3). Its use after 12 h of rupture in term prelabor rupture of the membranes is therefore recommended (grade C). When antibiotic prophylaxis is indicated, intravenous beta-lactams are recommended (grade C). Induction of labor with oxytocin (LE1), prostaglandin E2 (LE1), or misoprostol (LE1) is associated with shorter rupture-to-delivery intervals than expectant management; immediate induction is not, however, associated with lower rates of neonatal infection (LE1), even among women with a positive GBS vaginal swab (LE2). Thus, expectant management can be offered without increasing the risk of neonatal infection (grade B). Induction of labor is not associated with either an increase or decrease in the cesarean rate (LE2), regardless of parity (LE2) or Bishop score at admission (LE3). Induction can thus be proposed without increasing the risk of cesarean delivery (grade B). No induction method (oxytocin, dinoprostone, misoprostol, or Foley catheter) has demonstrated superiority over any another method for reducing rates of intrauterine or neonatal infection or of cesarean delivery or for shortening the rupture-to-delivery intervals, regardless of parity or the Bishop score. CONCLUSION Term prelabor rupture of membranes is a frequent event. A 12-hour interval without onset of spontaneous labor was chosen to differentiate a physiological condition from a potentially unsafe situation that justifies antibiotic prophylaxis. Expectant management or induction of labor can each be proposed, even in case of positive screening for group streptococcus. The decision should depend on the woman's wishes and maternity unit organization (professional consensus).

Abstract
BACKGROUND Esophageal atresia (EA) is a rare congenital malformation of the upper aerodigestive tract, which can be diagnosed antenatally in 50-65% of cases. Postnatal management differs according to the type of EA. No studies have evaluated the correlation of antenatal ultrasound findings with the type of EA. OBJECTIVE The main objective is to study the association between antenatal ultrasound signs and the type of EA. The secondary objective is to study the association between postnatal morbidity and the type of EA. METHOD We conducted a single-center retrospective study between May 2010 and August 2019. Fetuses with suspected prenatal EA and postnatal diagnosis confirmation were included. Postnatal confirmation of EA was performed during surgery for live births and by fetopathological examination for termination of pregnancy. Prenatal signs and postnatal morbidity were compared according to the type of EA. RESULTS We included 15 cases of postnatally confirmed EA, including 9 type 1EA, 5 type 3EA and 1 type 4EA (11 live births and 4 terminations of pregnancy). The gestational age at diagnosis was earlier in type 1EA: 22+0 [6-21,21-24] versus 30+0 [28+0-32+0] (P=0.03). Compared to type 3EA, type 1EA had a higher incidence of non-visible stomach bubble (89% versus 40%, P=0.09) and upper esophageal cul-de-sac dilatation (56% versus 0%, P=0.09). Neonatal morbidity in type 1EA was more severe with a longer hospital stay in neonatal intensive care. CONCLUSION The antenatal ultrasound signs seem to be more pronounced in case of type 1EA. Type 1EA is associated with severe morbidity compared to Type 3EA. Improving prenatal diagnosis of EA and its type allows a more accurate prognostic evaluation.

Transplacental transfer of glyburide in women with gestational diabetes and neonatal hypoglycemia risk. PLoS One 2020; 15:e0232002.

Abstract
Background In pregnant women with gestational diabetes, glyburide can be an alternative to insulin despite concerns about its transplacental transfer. However, transplacental transfer of glyburide is poorly quantified and the relationship between cord blood glyburide concentration and hypoglycemia has not been studied. Our objective was to quantify the transplacental transfer of glyburide at delivery and to study the association between the cord blood glyburide concentration and the risk of neonatal hypoglycemia in patients with gestational diabetes treated with glyburide. Methods and findings INDAO was a multicenter, noninferiority, randomized trial conducted between May 2012 and November 2016 in 914 women with singleton pregnancies and gestational diabetes. An ancillary study was conducted in the 87 patients of the Bicêtre University Hospital Center. The sample consisted of 46 patients with utilizable assays at delivery. The relationships between glyburide concentration and the time since the last intake of glyburide and between fetal glyburide concentration and neonatal hypoglycemia were modeled with linear or logistic regressions using fractional polynomials. There was placental transfer of glyburide at a fetal to maternal ratio of 62% (95% CI [50; 74]). Umbilical cord blood glyburide concentration decreased steeply after the last maternal glyburide intake. After 24 hours, the mean umbilical cord blood concentration was less than 5 ng/mL. Neonatal hypoglycemia risk was increased with an odds ratio of hypoglycemia equal to 3.70 [1.40–9.77] for each 10 ng/mL increase in the cord blood glyburide concentration. However, no newborns were admitted to the NICU because of clinical signs of hypoglycemia or for treatment of hypoglycemia. Conclusion Considering that neonatal glyburide exposure may be limited by stopping treatment a sufficient time before labor, there may still be a place for glyburide in the management of gestational diabetes.

Cervical ripening by prostaglandin E2 in patients with a previous cesarean section. J Gynecol Obstet Hum Reprod 2020; 49:101699.

Abstract
OBJECTIVE To assess the efficacy and safety of prostaglandin in inducing labor in pregnant women with one previous cesarean section. Secondly, to evaluate predictors of successful vaginal delivery in cervical ripening by prostaglandin in these women. STUDY DESIGN This was an observational, retrospective, single-center study conducted in a type 3 maternity unit at Bicêtre University Hospital between January 1, 2013 and December 31, 2016. Patients with one previous cesarean section, a singleton pregnancy, a fetus in the cephalic presentation with a medical indication for induction of labor and an unfavorable cervix (Bishop score less than 6) were included in the study. Cervical ripening was performed using a dinoprostone intravaginal device for a duration of 24 h. RESULTS A total of 153 patients were included in the study. The rate of vaginal delivery was 55.6 % (85/153) overall and 78.3 % (36/46) in the subgroup of 46 women with a previous vaginal delivery before or after the cesarean section. There was no difference in neonatal and maternal morbidity (defined by intraoperative wounds or postpartum hemorrhage or uterine rupture) and mortality between women who delivered vaginally and women who had a cesarean section. The two cases of complete uterine rupture have been reported for patients whose labor was induced by intravaginal prostaglandin followed by intravenous oxytocin. The total maternal morbidity rate was 11.8 % (n = 8/68) in the case of emergency cesarean section. Predictors of vaginal delivery were a history of vaginal delivery, the onset of labor following cervical ripening, and a higher Bishop score before and after the 24 h following the cervical ripening. CONCLUSION Cervical ripening by prostaglandin after previous cesarean delivery has a 56 % success rate, with a 1.3 % risk of uterine rupture, especially when prostaglandin is combined with oxytocin. Low-risk patients should be identified to propose cervical ripening by prostaglandin.

Two separate placental masses on ultrasound do not always indicate a dichorionic pregnancy. J Gynecol Obstet Hum Reprod 2020; 49:101694.

Abstract
Monochorionic pregnancies are associated with a higher risk of perinatal morbidity and mortality than dichorionic pregnancies. Early determination of chorionicity by an ultrasound exam between 11+0 and 14+0 weeks' gestation (WG) is essential for the subsequent management of twin pregnancies. The presence of the T-sign is the most specific sign for determination of monochorionicity. During the second trimester, the presence of two distinct placental masses has a lower specificity in determining the chorionicity. We report here two cases of a monochorionic pregnancy with a bipartite placenta, suggesting that a placenta with two separate masses, each with a distinct cord insertion is not always indicative of a dichorionic pregnancy.'

Abstract
Preterm premature rupture of membranes (PPROM) is associated with an increased risk of serious maternal, fetal, and neonatal morbidities. We compared neonatal outcomes of women with PPROM before 34+0 weeks of gestation according to inpatient or outpatient management policy. 587 women with PPROM >48 hours, 246 (41.9%) in the group with an inpatient care policy (ICP) and 341 (58.1%) in the group with an outpatient care policy (OCP), were identified in France, from 2009 to 2012. Neonatal outcomes were compared between the two groups using logistic regression. A second analysis was performed to compare inpatient care and effective outpatient care (discharge from hospital) through propensity score matching. The outcome was a neonatal composite variable including one or more of the neonatal morbidity complications. The perinatal composite outcome was 14.6% with the ICP and 15.5% with the OCP (p = 0.76). After using the 1:1 ratio propensity score matching, effective outpatient care was not associated with a significantly higher risk of the perinatal composite outcome (OR 0.88, CI 0.35 to 2.25; p = 0.80) compared with inpatient care. Outpatient care is not associated with an increased rate of obstetric or neonatal complications and can be an alternative to hospital care for women with uncomplicated PPROM.

Abstract
We report a multiplex family with a GATA1 gene mutation responsible for a massive fetal cerebral hemorrhage occurring at 36 weeks. Two other stillbirth cousins presented with fetal hydrops and congenital hemochromatosis' phenotype at 37 and 12 weeks of gestation. Molecular screening revealed the presence of a c.613G>A pathogenic allelic variation in exon 4 of GATA1 gene in the 3 male siblings and their carrier mothers. The diagnosis of a GATA1 gene mutation may be suspected in cases of male fetuses with intracerebral bleeding, particularly if a history of prior fetal loss(es) and mild maternal thrombocytopenia are also present.

Congenital diaphragmatic hernia has a better prognosis when associated with a hernia sac. Prenat Diagn 2018; 38:638-644.

Abstract
OBJECTIVE To evaluate neonatal mortality and morbidity up to 6 months in neonates with congenital diaphragmatic hernia (CDH) with or without a hernia sac. METHODS Seventy-two cases of isolated CDH were included in a retrospective single-center study between January 2010 and December 2016. Hernia sac was defined at the time of surgery or at postmortem examination if the neonate died before surgery. RESULTS Seventeen newborns (23.6%) had a hernia sac. Survival at 6 months was significantly greater for isolated CDH with a hernia sac: 100% versus 63.6% (P = .003). High-frequency oscillatory ventilation was used significantly more in the no hernia sac group (P = .04). At surgery, the need for patch repair was significantly lower in the hernia sac group: 12% versus 50% (P = .005). The prenatal observed/expected lung-to-head ratio was significantly higher in the hernia sac group than in the no hernia sac group: 49.7% versus 38.6% (P < .05). CONCLUSION The presence of a hernia sac in CDH is associated with better outcome, especially survival at 6 months. If the presence of a hernia sac is recognized as a particular entity, which carries a good prognosis, it is necessary to be able to diagnose it prenatally, especially in the era of prenatal fetal surgery.

Prognosis of isolated congenital diaphragmatic hernia using lung-area-to-head-circumference ratio: variability across centers in a national perinatal network. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2018; 51:208-213.

Abstract
OBJECTIVE Congenital diaphragmatic hernia (CDH) is a severe anomaly. The observed-to-expected lung-area-to-head-circumference ratio (o/e-LHR) has been shown to provide a useful prediction of subsequent survival of fetuses with CDH in referral centers with expertise and a large caseload. However, the accuracy of o/e-LHR measurements in general fetal medicine units with less expertise is not well known. The aim of this study was to evaluate the capacity of o/e-LHR to provide a useful prediction of mortality of fetuses with CDH when the measurement is performed in fetal medicine units with different levels of expertise. METHODS Between January 2008 and November 2013, 305 live births with expectantly managed left-sided isolated CDH were recorded in the database of the French National Center for Rare Diseases (31 centers) and followed up after birth. Centers were grouped into two categories according to their mean annual CDH caseload over the study period: large centers with an average of ≥ 14 cases and smaller centers with < 14 cases per year. The relationship between o/e-LHR and 28-day and 6-month mortality was modeled using fractional polynomials and the predictive value of o/e-LHR was quantified using the area under the receiver-operating characteristics curve. Comparisons between the two center categories were carried out. Analyses were adjusted for potential confounders such as thoracic herniation of the liver and gestational age at birth and at diagnosis. RESULTS During the study period, two large centers managed a total of 82 CDH cases and 29 smaller centers a total of 223 CDH cases. Overall, there was a significant inverse relationship between 28-day mortality rate and o/e-LHR, which decreased from 54% when o/e-LHR was 20% to 6% when o/e-LHR was 75% (P < 0.01). When the category of center was considered, adjusted associations between o/e-LHR and 28-day mortality were significantly different (P = 0.032) between large and smaller centers. The ability to predict survival at 28 days postpartum based on o/e-LHR was better in large centers; for a specificity of 0.30, the sensitivity was 0.71 in large centers and 0.55 in smaller ones. The results were similar for 6-month mortality. CONCLUSIONS Our results show that o/e-LHR measured on two-dimensional ultrasound is a good indicator of neonatal prognosis in cases of CDH that may be used even in fetal medicine centers with a small caseload. However, our results also suggest that LHR measurement may be difficult to perform correctly. Therefore, appropriate training should be offered to professionals. Copyright © 2017 ISUOG.

Abstract
OBJECTIVE To report the first 6 months of experience of a nongovernmental-organization-managed obstetric care unit in a war refugee camp, with problems encountered and solutions implemented. DESIGN Prospective observational study of the maternity activity of Gynécologie Sans Frontières (GSF). SETTING GSF's maternity unit, in Zaatari camp (Jordan). POPULATION All pregnant women among Syrian refugees who came to the unit for delivery. METHODS The GSF's maternity unit is a light structure built with three tents, permitting low-risk pregnancy care and childbirth. Emergency cesarean deliveries were performed in the Moroccan army field hospital. High-risk pregnancies were transferred to Al Mafraq or Amman Hospital (Jordan) after assessment. MAIN OUTCOME MEASURES Delivery characteristics, indications for referral. RESULTS From September 2012 to February 2013, 371 women attended the unit and 299 delivered in it. Delivery rates increased from 5/month to 112/month over the period. Mean gestational age at birth was 39(+3) gestational weeks (SD = 1.9). Median birthweight was 3100 g (25-75% interquartile range 2840-3430 g). Spontaneous vaginal deliveries were dominant and the major maternal complication was postpartum hemorrhage (n = 13). Eighty-two women were referred to Al Mafraq or Amman hospitals, mainly for preterm labor (32%) and congenital malformations (11%). We managed one case of stillbirth. Maternal mortality did not occur. CONCLUSIONS Despite the difficulties of war, high-risk pregnant women were properly identified, permitting referrals when required. Cooperation with other nongovernmental organizations, including the United Nations High Commissioner for Refugees, was essential for the management of situations at risk of complications and to contain perinatal and maternal mortality.
