Population-based surveillance of congenital anomalies over 40 years (1981-2020): Results from the Paris Registry of Congenital Malformations (remaPAR). J Gynecol Obstet Hum Reprod 2024; 53:102780. [PMID: 38552958 DOI: 10.1016/j.jogoh.2024.102780] [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: 12/21/2023] [Revised: 02/13/2024] [Accepted: 03/25/2024] [Indexed: 04/01/2024]
Abstract
INTRODUCTION Registries of congenital anomalies (CAs) play a key role in the epidemiological surveillance of CAs. The objective was to estimate the prevalence of CAs and proportions of prenatal diagnosis, terminations of pregnancy for fetal anomaly (TOPFA) and infant mortality in the Paris Registry of Congenital Malformations (remaPAR) over 40 years, from 1981 to 2020. MATERIAL AND METHODS remaPAR records all births (live births, stillbirths ≥22 weeks of gestation and TOPFA at any gestational age) with CAs detected prenatally until the early neonatal period. We estimated the prevalence of CAs and proportions of prenatal diagnosis, TOPFA and infant mortality, overall and for a selected group of CAs in 3-year intervals. RESULTS The prevalence of CAs remained stable during the study period: 2.9 % of total births and 2.1 % of live births. Genetic anomalies were the most frequent subgroup (about 23 %), followed by congenital heart defects (about 22 %) and limb defects (about 20 %). Among non-genetic anomalies, the prevalence per 10,000 births was the highest for hypospadias (about 18 %) and the lowest for bilateral renal agenesis (about 1 %). Prenatal diagnoses increased from about 17 % in the 1980s to approximately 70 % in the most recent period (2018-2020), whereas the proportion of early TOPFA <16 weeks of gestation increased from 0.4 % to 14 %. Infant mortality ranged from 0 % for transverse limb reduction defects to 86 % for hypoplastic left heart syndrome. CONCLUSION The overall prevalence of CAs was fairly stable in Paris from 1981 to 2020. Prenatal diagnoses substantially increased, accompanied by much smaller increases in TOPFA.

Trends in Maternal Mortality From Obstetric Hemorrhage in France: 15 Years of Confidential Enquiry Into Maternal Deaths. Anesth Analg 2024:00000539-990000000-00822. [PMID: 38781094 DOI: 10.1213/ane.0000000000006864] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/25/2024]
Abstract
BACKGROUND The aim of this study was to assess temporal trends in incidence and underlying causes of maternal deaths from obstetric hemorrhage in France and to describe clinical care before and after implementation of the first national guidelines published in 2004 and updated in 2014. METHODS Data from all hemorrhage-related maternal deaths between 2001 and 2015 were extracted from the French Confidential Enquiry into Maternal Deaths. We compared the maternal mortality ratio (MMR), cause of obstetric hemorrhage, and death preventability by triennium. Critical care, transfusion, and obstetric management among women who died were described for 2001 to 2003 and 2013 to 2015. RESULTS The MMR from obstetric hemorrhage significantly decreased over time from 2.3 of 100,000 livebirths (54 of 2,391,551) in 2001 to 2003 to 0.8 of 100,000 livebirths (19 of 2,412,720) in 2013 to 2015. In 2001 to 2003, uterine atony accounted for 50% (27 of 54) of maternal deaths vs 21% (4 of 19) in 2013 to 2015. As compared to 2001 to 2003, an increased proportion of women had hemodynamic continuous monitoring in 2013 to 2015 (30%, 9 of 30, vs 47%, 8 of 18) and received vasopressor infusion therapy (57%, 17 of 30, vs 72%, 13 of 18), and a smaller proportion was extubated during active hemorrhage (17%, 5 of 30, vs 0 of 18). Transfusion therapy was initiated more frequently and earlier in 2013 to 2015 (71 vs 58 minutes). In 2013 to 2015, 88% of maternal deaths due to hemorrhage remained preventable. The main identified improvable care factors were related to delays in diagnosis and surgical management, particularly after cesarean delivery. CONCLUSIONS Maternal mortality by obstetric hemorrhage decreased dramatically in France between 2001 and 2015, particularly mortality due to uterine atony. Among women who died, we detected fewer instances of substandard transfusion management or critical care. Nevertheless, opportunities for improvement were observed in most of the recent cases.

Tocolysis after preterm prelabor rupture of membranes and 5-year outcomes: a population-based cohort study. Am J Obstet Gynecol 2024; 230:570.e1-570.e18. [PMID: 37827270 DOI: 10.1016/j.ajog.2023.10.010] [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: 07/12/2023] [Revised: 09/29/2023] [Accepted: 10/06/2023] [Indexed: 10/14/2023]
Abstract
BACKGROUND The administration of tocolytics after preterm prelabor rupture of membranes remains a controversial practice. In theory, reducing uterine contractility should delay delivery and allow for optimal antenatal management, thereby reducing the risks for prematurity and adverse consequences over the life course. However, tocolysis may be associated with neonatal death or long-term adverse neurodevelopmental outcomes, mainly related to prolonged fetal exposure to intrauterine infection or inflammation. In a previous study, we showed that tocolysis administration was not associated with short-term benefits. There are currently no data available to evaluate the impact of tocolysis on neurodevelopmental outcomes in school-aged children born prematurely in this clinical setting. OBJECTIVE This study aimed to investigate whether tocolysis administered after preterm prelabor rupture of membranes is associated with neurodevelopmental outcomes at 5.5 years of age. STUDY DESIGN We used data from a prospective, population-based cohort study of preterm births recruited in 2011 (referred to as the EPIPAGE-2 study) and for whom the results of a comprehensive medical and neurodevelopmental assessment of the infant at age 5.5 years were available. We included pregnant individuals with preterm prelabor rupture of membranes at 24 to 32 weeks' gestation in singleton pregnancies with a live fetus at the time of rupture, birth at 24 to 34 weeks' gestation, and participation of the infant in an assessment at 5.5 years of age. Exposure was the administration of any tocolytic treatment after preterm prelabor rupture of membranes. The main outcome was survival without moderate to severe neurodevelopmental disabilities at 5.5 years of age. Secondary outcomes included survival without any neurodevelopmental disabilities, cerebral palsy, full-scale intelligence quotient, developmental coordination disorders, and behavioral difficulties. A propensity-score analysis was used to minimize the indication bias in the estimation of the treatment effect on outcomes. RESULTS Overall, 596 of 803 pregnant individuals (73.4%) received tocolytics after preterm prelabor rupture of membranes. At the 5.5-year follow-up, 82.7% and 82.5% of the children in the tocolysis and no tocolysis groups, respectively, were alive without moderate to severe neurodevelopmental disabilities; 52.7% and 51.1%, respectively, were alive without any neurodevelopmental disabilities. After applying multiple imputations and inverse probability of treatment weighting, we found no association between the exposure to tocolytics and survival without moderate to severe neurodevelopmental disabilities (odds ratio, 0.93; 95% confidence interval, 0.55-1.60), survival without any neurodevelopmental disabilities (odds ratio, 1.02; 95% confidence interval, 0.65-1.61), or any of the other outcomes. CONCLUSION There was no difference in the neurodevelopmental outcomes at age 5.5 years among children with and without antenatal exposure to tocolysis after preterm prelabor rupture of membranes. To date, the health benefits of tocolytics remain unproven, both in the short- and long-term.

Maintenance oxytocin in the immediate postpartum period: Frequency, determinants and practices in a tertiary maternity unit. J Gynecol Obstet Hum Reprod 2024; 53:102761. [PMID: 38431190 DOI: 10.1016/j.jogoh.2024.102761] [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: 11/27/2023] [Revised: 02/12/2024] [Accepted: 02/28/2024] [Indexed: 03/05/2024]
Abstract
OBJECTIVE To prevent post-partum haemorrhage (PPH), national and international guidelines recommend the administration of a prophylactic injection of oxytocin after all vaginal births. Although additional maintenance oxytocin is not recommended in the immediate postpartum, its administration is quite common (30 % of French births in 2021). To assess in a single center, the frequency and determinants associated with the administration of maintenance oxytocin in immediate postpartum. STUDY DESIGN A retrospective observational single-centre study was conducted in a tertiary-care university centre in Paris (France), with data from April-May 2022. All women who gave birth vaginally at or after 37 weeks, except for those with immediate PPH. Univariate and multivariate analysis were performed to compare determinants between the group receiving maintenance oxytocin and the control group without this intervention. A sensitivity analysis in a population of women at low risk of PPH was performed. Maternal, obstetrical, perinatal and organisational determinants were collected. RESULTS This study included 584 patients, 278 (47.6 %) of whom received maintenance oxytocin. We observed a significantly higher rate of maintenance oxytocin administration to parous women (OR 1.57, 90 %CI 1.09-2.27) and women with a history of PPH (OR 2.88, 90 %CI 1.08-9.08). Additional maintenance oxytocin was also administered more often when the midwife handling the birth had more than 5 years of practice since completion of training (OR 1.77, 1.24-2.53) or during night-time births (OR 1.47, 90 %CI 1.03-2.10). CONCLUSION Maintenance oxytocin administration is a frequent practice, performed for almost half the patients in our center. This practice is associated with maternal and obstetric factors, but also with health professionals' individual decisions and practices.

Analysis of MRI brain biometrics in fetuses monitored for intra uterine growth restriction and their prognostic value: Results of a prospective multicenter study. Eur J Obstet Gynecol Reprod Biol 2024; 298:91-97. [PMID: 38735121 DOI: 10.1016/j.ejogrb.2024.04.043] [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: 12/27/2023] [Revised: 04/11/2024] [Accepted: 04/29/2024] [Indexed: 05/14/2024]
Abstract
OBJECTIVE Show a prognostic value of brain changes in fetuses with intra uterine growth restriction (IUGR) on early neonatal outcome. STUDY DESIGN We prospectively recruited pregnant women whose fetuses presented fetal weight < 5th centile. A brain MRI was performed between 28 and 32 weeks of gestation (WG). Several brain biometrics were measured (as fronto-occipital diameter (FOD) and transverse cerebellar diameter (TCD)). Neonatal prognosis was evaluated according to a composite criterion. RESULTS Of the 78 patients included, 62 had a fetal brain MRI. The mean centile value of FOD was lower in the unfavorable outcome group (n = 9) compared to the favorable outcome group (n = 53) (24.5 ± 16.8 vs. 8.6 ± 13.2, p = 0.004). The ROC curve for predicting risk of unfavorable neonatal outcome based on FOD presented an area under the curve of 0.81 (95 % CI, [0.63---0.99]) and a threshold determined at the 3rd centile was associated with sensitivity of 0.78 and a specificity of 0.89. In multivariate analysis, a FOD less than the 3rd centile was significantly associated with an unfavorable neonatal risk. There also was a reduction in TCD (25.5 ± 21.5 vs. 10.4 ± 10.4, p = 0.03) in the unfavorable neonatal outcome group. CONCLUSION We found an association between a reduction in FOD and TCD in fetal MRIs conducted between 28 and 32 WG in fetuses monitored for IUGR with an unfavorable neonatal outcome. Our results suggest that these biometric changes could constitute markers of poor neonatal prognosis.

Severe postpartum hemorrhage and the risk of adverse maternal outcome: A comparative analysis of two population-based studies in France and the Netherlands. Prev Med Rep 2024; 40:102665. [PMID: 38435415 PMCID: PMC10907197 DOI: 10.1016/j.pmedr.2024.102665] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2023] [Revised: 02/14/2024] [Accepted: 02/20/2024] [Indexed: 03/05/2024] Open
Abstract
Objectives Among women with severe PPH (sPPH) in France and the Netherlands, we compared incidence of adverse maternal outcome (major obstetric hemorrhage (≥2.5L blood loss) and/or hysterectomy and/or mortality) by mode of delivery. Second, we compared use and timing of resuscitation and transfusion management, second-line uterotonics and uterine-sparing interventions (intra-uterine tamponade, compression sutures, vascular ligation, arterial embolization) by mode of delivery. Methods Secondary analysis of two population-based studies of women with sPPH in France and the Netherlands. Women were selected by a harmonized definition for sPPH: (total blood loss ≥ 1500 ml) AND (blood transfusion of ≥ 4 units packed red blood cells and/or multicomponent blood transfusion). Findings Incidence of adverse maternal outcome after vaginal birth was 793/1002, 9.1 % in the Netherlands versus 88/214, 41.1 % in France and 259/342, 76.2% versus 160/270, 59.3% after cesarean. Hemostatic agents such as fibrinogen were administered less frequently (p < 0.001) in the Netherlands (vaginal birth: 83/1002, 8.3% versus 105/2014, 49.5% in France; cesarean: 47/342, 13.7% and 152/270, 55.6%). Second-line uterotonics were started significantly later after PPH-onset in the Netherlands than France (vaginal birth: 46 versus 25 min; cesarean: 45 versus 18 min). Uterine-sparing interventions were less frequently (p < 0.001) applied in the Netherlands after vaginal birth (394/1002,39.3 %, 134/214, 62.6%) and cesarean (133/342, 38.9 % and 155/270, 57.4%), all initiated later after onset of refractory PPH in the Netherlands. Interpretation Incidence of adverse maternal outcome was higher among women with sPPH in the Netherlands than France regardless mode of birth. Possible explanatory mechanisms are earlier and more frequent use of second-line uterotonics and uterine-sparing interventions in France compared to the Netherlands.

Abstract
OBJECTIVE Post-partum hemorrhage (PPH) is the leading preventable cause of worldwide maternal morbidity and mortality. Risk factors for psychological disorders following PPH are currently unknown. HELP-MOM study aimed to determine the incidence and identify risk factors for psychological disorders following PPH. METHODS HELP-MOM study was a prospective, observational, national, and multicentre study including patients who experienced severe PPH requiring sulprostone. The primary endpoint was the occurrence of psychological disorders (anxiety and/or post-traumatic disorder and/or depression) following PPH, assessed at 1, 3, and 6 months after delivery using HADS, IES-R, and EPDS scales. RESULTS Between November 2014 and November 2016, 332 patients experienced a severe PPH and 236 (72%) answered self-questionnaires at 1, 3, and 6 months. A total of 161 (68%) patients declared a psychological disorder following severe PPH (146 (90.1%) were screened positive for anxiety, 96 (58.9%) were screened positive for post-traumatic stress disorder, and 94 (57.7%) were screened positive for post-partum depression). In multivariable analysis, the use of intra-uterine tamponnement balloon was associated with a lower risk to be screened positive for psychological disorder after severe PPH (OR = 0.33 [IC95% 0.15-0.69], p = 0.004, and after propensity score matching (OR=0.34 [IC95% 0.12-0.94], p = 0.04)). Low hemoglobin values during severe PPH management were associated with a higher risk of being screened positive for psychological disorders. Finally, we did not find differences in desire or pregnancy between patients without or with psychological disorders occurring in the year after severe PPH. DISCUSSION Severe PPH was associated with significant psychosocial morbidity including anxiety, post-traumatic disorder, and depression. This should engage a psychological follow-up. Large cohorts are urgently needed to confirm our results. REGISTRATION ClinicalTrials.gov under number NCT02118038.

Re-evaluating fetal scalp pH thresholds: An examination of fetal pH variations during labor. Acta Obstet Gynecol Scand 2024; 103:479-487. [PMID: 38059396 PMCID: PMC10867374 DOI: 10.1111/aogs.14739] [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: 10/03/2023] [Revised: 11/09/2023] [Accepted: 11/14/2023] [Indexed: 12/08/2023]
Abstract
INTRODUCTION Since the 1970s, fetal scalp blood sampling (FSBS) has been used as a second-line test of the acid-base status of the fetus to evaluate fetal well-being during labor. The commonly employed thresholds that delineate normal pH (>7.25), subnormal (7.20-7.25), and pathological pH (<7.20) guide clinical decisions. However, these experienced-based thresholds, based on observations and common sense, have yet to be confirmed. The aim of the study was to investigate if pH drop rate accelerates at the common thresholds (7.25 and 7.20) and to explore the possibility of identifying more accurate thresholds. MATERIAL AND METHODS A retrospective study was conducted at a tertiary maternity hospital between June 2017 and July 2021. Patients with at least one FSBS during labor for category II fetal heart rate and delivery of a singleton cephalic infant were included. The rate of change in pH value between consecutive samples for each patient was calculated and plotted as a function of pH value. Linear regression models were used to model the evolution of the pH drop rate estimating slope and standard errors across predefined pH intervals. Exploration of alternative pH action thresholds was conducted. To explore the independence of the association between pH value and pH drop rate, multiple linear regression adjusted on age, body mass index, parity, oxytocin stimulation and suspected small for gestational age was performed. RESULTS We included 2047 patients with at least one FSBS (total FSBS 3467); with 2047 umbilical cord blood pH, and a total of 5514 pH samples. Median pH values were 7.29 1 h before delivery, 7.26 30 min before delivery. The pH drop was slow between 7.40 and 7.30, then became more pronounced, with median rates of 0.0005 units/min at 7.25 and 0.0013 units/min at 7.20. Out of the alternative pH thresholds, 7.26 and 7.20 demonstrated the best alignment with our dataset. Multiple linear regression revealed that only pH value was significantly associated to the rate of pH change. CONCLUSIONS Our study confirms the validity and reliability of current guideline thresholds for fetal scalp pH in category II fetal heart rate.

Impact of an e-learning training for interpreting intrapartum fetal heart rate monitoring to avoid perinatal asphyxia: A before-after multicenter observational study. J Gynecol Obstet Hum Reprod 2024; 53:102736. [PMID: 38278214 DOI: 10.1016/j.jogoh.2024.102736] [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: 11/17/2023] [Revised: 01/23/2024] [Accepted: 01/23/2024] [Indexed: 01/28/2024]
Abstract
INTRODUCTION Perinatal asphyxia, a condition that results from compromised placental or pulmonary gas exchange during the birth process, is rare but can lead to serious neonatal and long-term consequences. The visual analysis of cardiotocography (CTG) is designed to avoid perinatal asphyxia, but its interpretation can be difficult. Our aim was to test the impact of an e-learning training program for interpreting CTG on the rate of avoidable perinatal asphyxia at term. METHOD We conducted a retrospective multicenter before-after study comparing two periods, before and after the implementation of e-learning training program from July 1, 2016 to December 31, 2016, in CTG interpretation for midwives and obstetricians in five maternity hospitals in the Paris area, France. The training involved theoretical aspects such as fetal physiology and heart rhythm abnormalities, followed by practical exercises using real case studies to enhance skills in interpreting CTG. We included all term births that occurred between the "before" period (July 1 to December 31, 2014) and the "after period (January 1 to June 30, 2017). We excluded multiple pregnancies, antenatal detection of congenital abnormalities, breech births and all scheduled caesarean sections. Perinatal asphyxia cases were analyzed by a pair of experts consisting of midwives and obstetricians, and avoidability of perinatal asphyxia was estimated. The main criterion was the prevalence of avoidable perinatal asphyxia. RESULTS The e-learning program was performed by 83 % of the obstetrician-gynecologists and 65 % of the midwives working in the delivery rooms of the five centers. The prevalence of perinatal asphyxia was 0.45 % (29/7902 births) before the training and 0.54 % (35/7722) after. The rate of perinatal asphyxia rated as avoidable was 0.30 % of live births before the training and 0.28 % after (p = 0.870). The main causes of perinatal asphyxia deemed avoidable were delay in reactions to severe CTG anomalies and errors in the analysis and interpretation of the CTG. These causes did not differ between the two periods. CONCLUSION One session of e-learning training to analyze CTG was not associated with a reduction in avoidable perinatal asphyxia. Other types of e-learning, repeated and implemented over a longer period should be evaluated.

Abstract
OBJECTIVE To assess the external validity and clinical relevance of current references for umbilical artery resistance index (UA RI) in daily practice. METHODS Retrospective cross-sectional single center study including all UA RI measurements between 22 and 40 gestational weeks (GW) from distinct patients between 2014 and 2022. Patients with normal pregnancies and normal neonatal outcomes that had an UA RI measurement between 2014 and 2019 were used to calculate reference ranges. The established reference for the 95th centile was compared to two current references. The clinical relevance of the established reference was tested by comparing neonatal outcomes according to the 95th percentile among the consecutive distinct patients between 2020 and 2022. RESULTS Among the 13342 consecutive distinct patients with a singleton pregnancy that had an UA RI measurement between 22 and 40 GW between 2014 and 2022, 5298 patients were included to establish the reference ranges, and 3634 patients to validate these ranges. For each gestational age, the established references were similar to current references. Using the established references, the proportion of patients presenting an UA RI>95th percentile among the patients with normal pregnancies in the validation population was comparable to the proportion when using the two current references. Among the validation population, 268 patients (7.4 %) (95%CI[6.5-8.2]) presented an UA RI ≥ 95th percentile. Of these 268 patients, 67.9% had a SGA newborn (versus 19.2%, p<0.001) and 59% a preterm birth (versus 13.9%, p<0.001). CONCLUSIONS The reference range obtained from daily practice is clinically relevant and similar to current references.

Abstract
Our team was confronted with a situation of stubborn refusal of care, including the indication of a cesarean section for an adult patient able to express her wishes. This refusal was formulated during pregnancy follow-up, during the discussion of the birth plan and during delivery, the patient having accepted the indication of a possible emergency cesarean section under general anesthesia only in the occurrence of severe fetal heart rate abnormalities. The impasse forced caregivers to violate the rules of good clinical practice, which indicated the performance of a cesarean section, and to wait for a complication to arise in order to be able to act, taking the risk of intervening too late. This situation has led to direct risks to the health of the mother and the unborn child, without putting the life of either of them in imminent danger. Finally, the time devoted to this patient in a tense organization was to the detriment of the care of other patients.

Induction of labor and risk of postpartum hemorrhage in women with vaginal delivery: A propensity score analysis. Int J Gynaecol Obstet 2024; 164:732-740. [PMID: 37568268 DOI: 10.1002/ijgo.15043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 07/13/2023] [Accepted: 07/25/2023] [Indexed: 08/13/2023]
Abstract
OBJECTIVE To explore the association between induction of labor (IOL) and postpartum hemorrhage (PPH) after vaginal delivery. METHODS We included women from the merged database of three randomized prospective trials (TRACOR, CYTOCINON, and TRAAP) that measured postpartum blood loss precisely, with standardized methods. IOL was considered overall and according to its method. The association between IOL and PPH was tested by multivariate logistic regression modeling, adjusted for confounders, and by propensity score matching. The role of potential intermediate factors, i.e. estimated quantity of oxytocin administered during labor and operative vaginal delivery, was assessed with structural equation modeling. RESULTS Labor was induced for 1809 of the 9209 (19.6%) women. IOL was associated with a significantly higher risk of PPH of 500 mL or more (adjusted odds ratio 1.56, 95% confidence interval 1.42-1.70) and PPH of 1000 mL or more (adjusted odds ratio 1.51, 95% confidence interval 1.16-1.96). The risk of PPH increased similarly regardless of the method of induction. The results were similar after propensity score matching (odds ratio for PPH ≥500 mL 1.57, 95% confidence interval 1.33-1.87, odds ratio for PPH ≥1000 mL 1.57, 95% confidence interval 1.06-2.07). Structural equation modeling showed that 34% of this association was mediated by the quantity of oxytocin administered during labor and 1.3% by women who underwent operative vaginal delivery. CONCLUSION Among women with vaginal delivery, the risk of PPH is higher in those with IOL, regardless of its method, and after accounting for indication bias. The quantity of oxytocin administered during labor may explain one third of this association.

Prenatal diagnosis of isolated bilateral clubfoot: Is amniocentesis indicated? Acta Obstet Gynecol Scand 2024; 103:51-58. [PMID: 37942915 PMCID: PMC10755119 DOI: 10.1111/aogs.14716] [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: 05/22/2023] [Revised: 10/09/2023] [Accepted: 10/18/2023] [Indexed: 11/10/2023]
Abstract
INTRODUCTION The aim of this study is to evaluate the benefit of cytogenetic testing by amniocentesis after an ultrasound diagnosis of isolated bilateral talipes equinovarus. MATERIAL AND METHODS This multicenter observational retrospective study includes all prenatally diagnosed cases of isolated bilateral talipes equinovarus in five fetal medicine centers from 2012 through 2021. Ultrasound data, amniocentesis results, biochemical analyses of amniotic fluid and parental blood samples to test neuromuscular diseases, pregnancy outcomes, and postnatal outcomes were collected for each patient. RESULTS In all, 214 fetuses with isolated bilateral talipes equinovarus were analyzed. A first-degree family history of talipes equinovarus existed in 9.8% (21/214) of our cohort. Amniocentesis was proposed to 86.0% (184/214) and performed in 70.1% (129/184) of cases. Of the 184 karyotypes performed, two (1.6%) were abnormal (one trisomy 21 and one triple X syndrome). Of the 103 microarrays performed, two (1.9%) revealed a pathogenic copy number variation (one with a de novo 18p deletion and one with a de novo 22q11.2 deletion) (DiGeorge syndrome). Neuromuscular diseases (spinal muscular amyotrophy, myasthenia gravis, and Steinert disease) were tested for in 56 fetuses (27.6%); all were negative. Overall, 97.6% (165/169) of fetuses were live-born, and the diagnosis of isolated bilateral talipes equinovarus was confirmed for 98.6% (139/141). Three medical terminations of pregnancy were performed (for the fetuses diagnosed with Down syndrome, DiGeorge syndrome, and the 18p deletion). Telephone calls (at a mean follow-up age of 4.5 years) were made to all parents to collect medium-term and long-term follow-up information, and 70 (33.0%) families were successfully contacted. Two reported a rare genetic disease diagnosed postnatally (one primary microcephaly and one infantile glycine encephalopathy). Parents did not report any noticeably abnormal psychomotor development among the other children during this data collection. CONCLUSIONS Despite the low rate of pathogenic chromosomal abnormalities diagnosed prenatally after this ultrasound diagnosis, the risk of chromosomal aberration exceeds the risks of amniocentesis. These data may be helpful in prenatal counseling situations.

Timing of antenatal corticosteroids and survival without neurologic disabilities at 5½ years in children born before 35 weeks of gestation. Am J Obstet Gynecol 2023; 229:675.e1-675.e18. [PMID: 37394223 DOI: 10.1016/j.ajog.2023.06.047] [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: 02/04/2023] [Revised: 06/21/2023] [Accepted: 06/27/2023] [Indexed: 07/04/2023]
Abstract
BACKGROUND The efficacy of antenatal corticosteroids for neonatal preterm complications wanes beyond 7 days after treatment. The neurodevelopmental effects of longer treatment-to-birth intervals have not been adequately evaluated. OBJECTIVE This study aimed to assess the impact of antenatal corticosteroid timing on survival without moderate or severe neurologic disabilities at 5½ years. STUDY DESIGN This was a secondary analysis of the EPIPAGE-2 study, a national population-based cohort (France) that recruited neonates in 2011 and followed them up at 5½ years (results first reported in 2021). Participants were children born alive between 24+0 and 34+6 weeks, with a complete corticosteroid course, delivery >48 hours after the first injection, and neither limitation of care decided before birth nor severe congenital malformation. The study included 2613 children, 2427 of whom were alive at 5½ years; 71.9% (1739/2427) had a neurologic assessment at this age; 1537 had a clinical examination (complete for 1532), and 202 were assessed with a postal questionnaire. Exposure was defined as the interval between the first injection of the last antenatal corticosteroid course and delivery in days, studied in 2 categories (days 3-7 and after day 7), in 4 categories (days 3-7, 8-14, 15-21, and after day 21), and continuously in days. The main outcome was survival at 5½ years without moderate/severe neurologic disabilities, defined as moderate/severe cerebral palsy, or unilateral or bilateral blindness or deafness, or Full-Scale Intelligence Quotient 2 standard deviations below the mean. A multivariate analysis with a generalized estimated equation logistic regression model assessed the statistical association between the main outcomes and the interval from the first corticosteroid injection of the last course to birth. Multivariate analyses were adjusted for potential confounders, defined with a directed acyclic graph: gestational age in days, number of corticosteroid courses, multiple pregnancy, and cause of prematurity in 5 categories. Because neurologic follow-up was complete in only 63.2% of cases (1532/2427), the analyses used imputed data. RESULTS Among 2613 children, 186 died between birth and 5½ years. Overall survival was 96.6% (95% confidence interval, 95.9-97.0), and survival without moderate or severe neurologic disabilities was 86.0% (95% confidence interval, 84.7-87.0). Survival without moderate or severe neurologic disabilities was lower after day 7 (85.0%) than during the interval from day 3 to day 7 (87.0%) (adjusted odds ratio, 0.70; 95% confidence interval, 0.54-0.89). CONCLUSION The association of a >7-day interval between antenatal corticosteroid administration and birth with a lower rate of survival without moderate or severe neurologic disabilities among children aged 5½ years emphasizes the importance of better targeting women at risk of preterm delivery to optimize the timing and thus benefits of treatment.

Abstract
OBJECTIVES To summerize the results of the JUMODA study (JUmeaux MODe d'Accouchement) on the planned mode of delivery of twin pregnancy and the management of second twin delivery. METHODS JUMODA was a national observational prospective comparative study that took place between february 2014 and march 2015 in 176 french maternity units performing more than 1500 deliveries per year. Its main objectives were the comparison of neonatal and maternal morbidity according to the planned mode of delivery and the determination of the managements of second twin delivery associated with the best neonatal outcomes. To control for potential confounding factors and indication biases, statistical analyses comprized multivariate logistic regressions and matching on propensity scores. RESULTS The JUMODA study recruited 8823 women with twin delivery at or beyond 22 weeks of gestation. For twin pregnancies with a cephalic first twin at 32 weeks of gestation and beyond, severe neonatal morbidity was higher in the planned cesarean (150/2908 (5.2 %) than in the planned vaginal delivery group (199/8922 (2.2 %), aOR 1.56, 95 % CI 1.19-2.04). Increased neonatal morbidity in the planned cesarean delivery group was explained by higher severe morbidity in neonates born preterm (aOR 1.64, 95 % CI 1.13-2.39, for deliveries between 32+0 and 34+6 weeks of gestation, aOR 2.04, 95 % CI 1.22-3.41, for deliveries between 35+0 SA and 36+6 weeks of gestation) but not in neonates born at term (aOR 1.19, 95 % CI 0.58-2.44). In comparison with planned cesarean delivery, planned vaginal delivery was not associated with increased severe neonatal morbidity in case of breech presenting first twin after 32 weeks of gestation or with decreased survival witout severe neonatal morbidity in case of delivery before 32 weeks of gestation whatever the first twin presentation. In comparison with planned vaginal delivery, planned cesarean delivery was associated with increased severe maternal morbidity only in women aged 35 and higher. Delivery of non cephalic second twin was associated with similar severe neonatal morbidity rate than delivery of cephalic second twin. Finally, in case of cephalic second twin, internal version followed by total breech extraction was associated with less cesarean for the second twin but with higher severe neonatal morbidity in case of preterm birth in comparison with pushing efforts, ocytocin perfusion and artificial rupture of membranes. CONCLUSIONS Planned vaginal delivery is the planned mode of delivery to encourage for the majority of pregnant women with twins, whatever first twin presentation and gestational age at delivery. No management of cephalic second twin appears better than an other, its choice will rest on obstetrician preferences.

Efficacy of early intrauterine balloon tamponade for immediate postpartum hemorrhage after vaginal delivery: a randomized clinical trial. Am J Obstet Gynecol 2023; 229:542.e1-542.e14. [PMID: 37209893 DOI: 10.1016/j.ajog.2023.05.014] [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: 01/29/2023] [Revised: 05/08/2023] [Accepted: 05/14/2023] [Indexed: 05/22/2023]
Abstract
BACKGROUND Many questions remain about the appropriate use of intrauterine balloon devices in postpartum hemorrhage after vaginal delivery refractory to first-line uterotonics. Available data suggest that early use of intrauterine balloon tamponade might be beneficial. OBJECTIVE This study aimed to compare the effect of intrauterine balloon tamponade used in combination with second-line uterotonics vs intrauterine balloon tamponade used after the failure of second-line uterotonic treatment on the rate of severe postpartum hemorrhage in women with postpartum hemorrhage after vaginal delivery refractory to first-line uterotonics. STUDY DESIGN This multicenter, randomized, controlled, parallel-group, nonblinded trial was conducted at 18 hospitals and enrolled 403 women who had just given birth vaginally at 35 to 42 weeks of gestation. The inclusion criteria were a postpartum hemorrhage refractory to first-line uterotonics (oxytocin) and requiring a second-line uterotonic treatment with sulprostone (E1 prostaglandin). In the study group, the sulprostone infusion was combined with intrauterine tamponade by an ebb balloon performed within 15 minutes of randomization. In the control group, the sulprostone infusion was started alone within 15 minutes of randomization, and if bleeding persisted 30 minutes after the start of sulprostone infusion, intrauterine tamponade using the ebb balloon was performed. In both groups, if the bleeding persisted 30 minutes after the insertion of the balloon, an emergency radiological or surgical invasive procedure was performed. The primary outcome was the proportion of women who either received ≥3 units of packed red blood cells or had a calculated peripartum blood loss of >1000 mL. The prespecified secondary outcomes were the proportions of women who had a calculated blood loss of ≥1500 mL, any transfusion, an invasive procedure and women who were transferred to the intensive care unit. The analysis of the primary outcome with the triangular test was performed sequentially throughout the trial period. RESULTS At the eighth interim analysis, the independent data monitoring committee concluded that the incidence of the primary outcome did not differ between the 2 groups and stopped inclusions. After 11 women were excluded because they met an exclusion criterion or withdrew their consent, 199 and 193 women remained in the study and control groups, respectively, for the intention-to-treat analysis. The women's baseline characteristics were similar in both groups. Peripartum hematocrit level change, which was needed for the calculation of the primary outcome, was missing for 4 women in the study group and 2 women in the control group. The primary outcome occurred in 131 of 195 women (67.2%) in the study group and 142 of 191 women (74.3%) in the control group (risk ratio, 0.90; 95% confidence interval, 0.79-1.03). The groups did not differ substantially for rates of calculated peripartum blood loss pf ≥1500 mL, any transfusion, invasive procedure, and admission to an intensive care unit. Endometritis occurred in 5 women (2.7%) in the study group and none in the control group (P=.06). CONCLUSION The early use of intrauterine balloon tamponade did not reduce the incidence of severe postpartum hemorrhage compared with its use after the failure of second-line uterotonic treatment and before recourse to invasive procedures.

Mother-child separation after twin birth in a maternity unit with an appropriate level of neonatal care. Int J Gynaecol Obstet 2023; 163:563-571. [PMID: 37194441 DOI: 10.1002/ijgo.14851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 04/11/2023] [Accepted: 04/24/2023] [Indexed: 05/18/2023]
Abstract
OBJECTIVE To evaluate the mother-child separation rate in twin pregnancies delivered in maternity units offering an appropriate level of neonatal care. METHODS JUMODA is a French, prospective, population-based cohort study of twin deliveries, including 7998 women who gave birth in maternity units with appropriate levels of neonatal care based on thresholds for weeks of gestational age (wGA) and birth weight according to French guidelines: level I (≥36 wGA), IIA (≥34 wGA), IIB (≥32 wGA and ≥ 1500 g), and IIII (<32 wGA or < 1500 g). The primary outcome was mother-child separation, defined as the transfer of at least one twin or the mother to another hospital. RESULTS Mother-child separation occurred in 2.1% of pregnancies. This rate was significantly higher in level I (4.8%, 95% confidence interval [CI] 1.5-12.5) and IIA (3.4%, 95% CI 2.4-4.7) compared with level IIB (1.6%, 95% CI 1.1-2.3) and level III maternity units (2.1%, 95% CI 1.9-2.8). In level IIA units, the rate of mother-child separation was higher for babies born between 34 and 36 wGA (8.3%) than for those born at 36 wGA or beyond (1.7%). In level IIb, the rate of mother-child separation for babies born between 32 and 34 wGA (7.5%) was higher than for those born between 34 and 36 wGA (2.1%) and at 36 wGA or beyond (0.9%). CONCLUSION Mother-child separation rates were low but differed by level of care. By using specific thresholds for twins to define levels of care, rather than data from singleton births, one-fifth of mother-child separations could have been avoided.

Abstract
AIM To describe the circumstances, causes and timing of death in extremely preterm infants. METHODS We included from the EPIPAGE-2 study infants born at 24-26 weeks in 2011 admitted to neonatal intensive care units (NICU). Vital status and circumstances of death were used to define three groups of infants: alive at discharge, death with or without withholding or withdrawing life-sustaining treatment (WWLST). The main cause of death was classified as respiratory disease, necrotizing enterocolitis, infection, central nervous system (CNS) injury, other or unknown. RESULTS Among 768 infants admitted to NICU, 224 died among which 89 died without WWLST and 135 with WWLST. The main causes of death were respiratory disease (38%), CNS injury (30%) and infection (12%). Among the infants who died with WWLST, CNS injury was the main cause of death (47%), whereas respiratory disease (56%) and infection (20%) were the main causes in case of death without WWLST. Half (51%) of all deaths occurred within the first 7 days of life, and 35% occurred within 8 and 28 days. CONCLUSION The death of extremely preterm infants in NICU is a complex phenomenon in which the circumstances and causes of death are intertwined.

Risk of disseminated intravascular coagulation in postpartum hemorrhage associated with intrauterine infection. J Gynecol Obstet Hum Reprod 2023; 52:102626.

Abstract
OBJECTIVE To evaluate the risk of disseminated intravascular coagulation (DIC) in postpartum hemorrhage (PPH) associated with intrauterine infection. MATERIAL AND METHODS A retrospective cohort study of pregnancies complicated by PPH performed at a tertiary academic center in France from 2017 through 2021. Patients giving birth after 22 weeks of gestation with PPH were eligible. Patients with a PPH associated with an intrauterine infection were compared to patients with a PPH without intrauterine infection. Intrauterine infection was defined by a composite criterion available at delivery. DIC was defined by a specific pregnancy DIC score. The association between DIC and intrauterine infection was assessed by logistic regression. The causal effect of intrauterine infection on DIC was estimated by mediation analysis. RESULTS Of 2,093 patients with PPH, 49 exposed to a clinical intrauterine infection were compared to 49 unexposed patients. The rate of DIC was higher in patients with than without infection (22 (45.8%) vs. 7 (14.6%), P = .001), and coagulation anomalies occurred sooner in patients with than without infection (7, 2-11 h vs. 14, 9-19 h, P < .001). In the multivariate analysis, intrauterine infection was the only factor independently associated with DIC (adjusted odds ratio 5.01, 95% CI 1.83-13.73). Mediation analysis showed that 14% (95% CI, 0-50%) of this association between intrauterine infection and DIC was mediated by severe PPH, and 86% resulted from the direct effect of intrauterine infection on DIC. CONCLUSION In PPH, intrauterine infection had a major direct effect on the occurrence, timing, and severity of DIC.

Comparison of quantitative and calculated postpartum blood loss after vaginal delivery. Am J Obstet Gynecol MFM 2023; 5:101065.

Abstract
BACKGROUND Because there is no consensus on the method of assessing postpartum blood loss, the comparability and relevance of the postpartum hemorrhage-related literature are questionable. Quantitative blood loss assessment using a volumetric technique with a graduated collector bag has been proposed to overcome limitations of intervention-based outcomes but remains partly subjective and potentially biased by amniotic fluid or missed out-of-bag losses. Calculated blood loss based on laboratory parameters has been studied and used as an objective method expected to reflect total blood loss. However, few studies have compared quantitative with calculated blood loss. OBJECTIVE This study aimed to compare the distribution of postpartum blood loss after vaginal delivery assessed by 2 methods-quantitative and calculated blood loss-and the incidence of abnormal blood loss with each method. STUDY DESIGN Data were obtained from the merged database of 3 multicenter, randomized controlled trials, all testing different interventions to prevent postpartum blood loss in individuals with a singleton live fetus at ≥35 weeks of gestation, born vaginally. All 3 trials measured blood loss volume by using a graduated collector bag. Hematocrit was measured in the eighth or ninth month of gestation and on day 2 postpartum. The 2 primary outcomes were: quantitative blood loss, defined by the total volume of blood loss measured in a graduated collector bag, and calculated blood loss, mathematically defined from the peripartum hematocrit change (estimated blood volume × [(antepartum hematocrit-postpartum hematocrit)/antepartum hematocrit], where estimated blood volume [mL]=booking weight [kg] × 85). We modeled the association between positive quantitative blood loss and positive calculated blood loss with polynomial regression and calculated the Spearman correlation coefficient. RESULTS Among the 8341 individuals included in this analysis, the median quantitative blood loss (100 mL; interquartile range, 50-275) was significantly lower than the median calculated blood loss (260 mL; interquartile range, 0-630) (P<.05). The incidence of abnormal blood loss was lower with quantitative blood loss than calculated blood loss for all 3 thresholds: for ≥500 mL, it was 9.6% (799/8341) and 32.3% (2691/8341), respectively; for ≥1000 mL, 2.1% (176/8341) and 11.5% (959/8341); and for ≥2000 mL, 0.1% (10/8341) and 1.4% (117/8341) (P<.05). Quantitative blood loss and calculated blood loss were significantly but moderately correlated (Spearman coefficient=0.44; P<.05). The association between them was not linear, and their difference tended to increase with blood loss. Negative calculated blood loss values occurred in 23% (1958/8341) of individuals; among them, >99% (1939/1958) had quantitative blood loss ≤500 mL. CONCLUSION Quantitative and calculated blood loss were significantly but moderately correlated after vaginal delivery. However, clinicians should be aware that quantitative blood loss is lower than calculated blood loss, with a difference that tended to rise as blood loss increased.

Abstract
RESEARCH QUESTION Is there a change in magnetic resonance imaging (MRI) criteria of diffuse and focal phenotypes of adenomyosis before and after pregnancy? DESIGN A retrospective, monocentric, observational study in a single academic tertiary referral centre for endometriosis diagnosis and management. Women were followed for symptomatic adenomyosis, and without a prior history of surgery who give birth after 24+0 weeks. For each patient, pelvic MRI pre- and post-pregnancy was performed by two experienced radiologists with the same image acquisition protocol. Diffuse and focal adenomyosis MRI presentation were analysed before and after pregnancy. RESULTS Between January 2010 and September 2020, of the 139 patients analysed, 96 (69.1%) had adenomyosis at MRI distributed as follow: 22 (15.8%) presented diffuse adenomyosis, 55 (39.6%) focal adenomyosis and 19 (13.7%) both phenotypes. The frequency of isolated diffuse adenomyosis on MRI was significantly lower before versus after pregnancy (n = 22 [15.8%] versus n = 41 [29.5%], P = 0.01). The frequency of isolated focal adenomyosis was significantly higher before pregnancy than after pregnancy (n = 55 [39.6%] versus n = 34 [24.5%], P = 0.01). The mean volume of all focal adenomyosis lesions on MRI decreased significantly after pregnancy, from 6.7 ± 2.5 mm3 to 6.4 ± 2.3 mm3, P = 0.01. CONCLUSION The current data indicate that, based on MRI, there is an increase in diffuse adenomyosis and a decrease in focal adenomyosis after pregnancy.

Abstract
INTRODUCTION Our objective was to study the strength of the association between meconium-stained amniotic fluid and severe morbidity among neonates of nulliparas with prolonged pregnancies. MATERIAL AND METHODS This was a secondary analysis of the NOCETER randomized trial that took place between 2009 and 2012 in which 11 French maternity units included 1373 nulliparas at 41+0 weeks of gestation onwards with a single live fetus in cephalic presentation. This analysis excluded patients with a cesarean delivery before labor and those with bloody amniotic fluid or of unreported consistency. The principal end point was a composite criterion of severe neonatal morbidity (neonatal death, 5-minute Apgar <7, convulsions in the first 24 h, meconium aspiration syndrome, mechanical ventilation ≥24 h, or neonatal intensive care unit admission for 5 days or more). The neonatal outcomes of pregnancies with thin or thick meconium-stained amniotic fluid were compared with those with normal amniotic fluid. The association between the consistency of the amniotic fluid and neonatal morbidity was tested by univariate and then multivariate analysis adjusted for gestational age at birth, duration of labor, and country of birth. RESULTS This study included 1274 patients: 803 (63%) in the group with normal amniotic fluid, 196 (15.4%) in the thin amniotic fluid group, and 275 (21.6%) in the thick amniotic fluid group. The neonates of patients with thick amniotic fluid had higher rates of neonatal morbidity than those of patients with normal amniotic fluid (7.3% vs. 2.2%; p < 0.001; adjusted relative risk [aRR] 3.3, 95% confidence interval [CI] 1.7-6.3), but those of patients with thin amniotic fluid did not (3.1% vs. 2.2%; p = 0.50; aRR 1.0, 95% CI, 0.4-2.7). CONCLUSIONS Among nulliparas at 41+0 weeks onwards, only thick meconium-stained amniotic fluid is associated with a higher rate of severe neonatal morbidity.

Publication rate and factors associated with publication of research projects by obstetrics residents in an academic department over 10 years. Eur J Obstet Gynecol Reprod Biol 2023; 287:161-165. [PMID: 37348382 DOI: 10.1016/j.ejogrb.2023.06.013] [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: 04/06/2023] [Revised: 06/07/2023] [Accepted: 06/13/2023] [Indexed: 06/24/2023]
Abstract
OBJECTIVES To determine the publication rate of mandatory research projects conducted by obstetrics residents and to evaluate the publication-associated factors and reported obstacles. STUDY DESIGN This retrospective cohort study included all consecutive residents in an academic obstetrics-gynecology department in Paris, France, between 2010 and 2020. All residents were required to conduct a research project. Information about publication was collected by searching PubMed. A closed-ended questions questionnaire was sent to former residents about their characteristics, subsequent professional development, and research project characteristics. Factors associated with publication were identified by univariable and multivariable analysis with logistic regression. RESULTS During the study period, 156 residents trained in our obstetrics-gynecology department. The overall publication rate was 30.8% (48/156) and the median time to publication 27 months (IQR, 18-37). The resident was first author in 36 (75.0%) publications. Among the 130 (83.3%) residents who completed the questionnaire, 43 (33%) had published their research project. Overall, 74/130 (60.8%) residents used their project for their mandatory medical thesis. Factors associated with publication in univariable analysis were younger age (median), completion of a PhD, planned career in academic medicine, prospective study design, presentation at a conference or congress and use their project for their medical thesis. The only factors associated with publication in the multivariable analysis were planned career in academic medicine (aOR 5.62 95 %CI[1.84-17.19]) and the prospective study design of the research project (aOR 6.1 95 %CI[1.24-29.56]). The main reasons for nonpublication reported by resident were lack of time and failure to complete the project. CONCLUSION Among the mandatory clinical research projects conducted by obstetrics residents over a decade in our department, 30.8% were published. The main factors associated with publication were planned career in academic medicine and a prospective design of the research project.

Chorionicity and neurodevelopmental outcomes at 5½ years among twins born preterm: the EPIPAGE2 cohort study. BJOG 2023. [PMID: 37069725 DOI: 10.1111/1471-0528.17460] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Revised: 01/25/2023] [Accepted: 02/21/2023] [Indexed: 04/19/2023]
Abstract
OBJECTIVE To compare the neurodevelopmental outcomes of preterm twins at 5½ years by chorionicity of pregnancy. DESIGN Prospective nationwide population-based EPIPAGE2 (Etude Epidémiologique sur les Petits Âges Gestationnels) cohort study. SETTING A total of 546 maternity units in France, between March and December 2011. POPULATION A total of 1126 twins eligible for follow-up at 5½ years. METHODS The association of chorionicity with outcomes was analysed using multivariate regression models. MAIN OUTCOME MEASURES Survival at 5½ years with or without neurodevelopmental disabilities (comprising cerebral palsy, visual, hearing, cognitive deficiency, behavioural difficulties or developmental coordination disorders) were described and compared by chorionicity. RESULTS Among the 1126 twins eligible for follow-up at 5½ years, 926 (82.2%) could be evaluated: 228 monochorionic (MC) and 698 dichorionic (DC). Based on chronicity and gestational age of birth, we found no significant differences for severe neonatal morbidity. The rates of moderate/severe neurobehavioral disabilities were similar in infants from DC pregnancies versus infants from MC pregnancies (OR 1.22, 95% CI 0.65-2.28). By gestational age and without twin-twin transfusion syndrome (TTTS), no difference according to chorionicity was found for all neurodevelopmental outcome measures. CONCLUSIONS The neurodevelopmental outcomes among preterm twins at 5½ years is similar, irrespective of chorionicity.

Failed induction of labor in term nulliparous women with an unfavorable cervix: Comparison of cervical ripening by two forms of vaginal prostaglandins (slow-release pessary and vaginal gel). J Gynecol Obstet Hum Reprod 2023; 52:102546. [PMID: 36740190 DOI: 10.1016/j.jogoh.2023.102546] [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: 11/24/2022] [Revised: 01/30/2023] [Accepted: 01/31/2023] [Indexed: 02/05/2023]
Abstract
OBJECTIVE To compare the rate of failed induction after cervical ripening by two forms of vaginal prostaglandins. MATERIAL AND METHODS This two-year retrospective study (January 1, 2016, through December 31, 2017) in two tertiary maternity units included nulliparous women with a singleton fetus in cephalic presentation and an unfavorable cervix requiring labor induction for prolonged pregnancy. The principal endpoint was the rate of failed induction, defined by the performance of a cesarean delivery before 6 cm of dilation. Cervical ripening was initiated by prostaglandins for 24 h, using a slow-release pessary (unit A) or a vaginal gel (unit B). The care protocol of the two groups after the first 24 h were similar. The women's individual characteristics were compared between the two units. The rates of failed induction were then compared between the two units, first by univariate and then by multivariable analysis adjusted for the characteristics that differed significantly between the units. RESULTS Among the 17,217 women delivered in the two maternity units during the study period, 178 met our inclusion criteria (125 in unit A (slow-release pessary) and 53 in unit B (vaginal gel)). The rate of failed induction was similar: 21.6% in unit A (slow-release pessary) and 17.0% in unit B (vaginal gel) (P = 0.48). The multivariate analysis did not show any difference about failed induction, time from the onset of induction to delivery, and vaginal delivery rate within 24h. CONCLUSION The rate of failed induction of labor did not differ between slow-release pessary and vaginal gel.

Second-trimester amniotic fluid proteins changes in subsequent spontaneous preterm birth. Acta Obstet Gynecol Scand 2023; 102:597-604. [PMID: 36918342 PMCID: PMC10072248 DOI: 10.1111/aogs.14544] [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: 10/16/2022] [Revised: 01/10/2023] [Accepted: 02/14/2023] [Indexed: 03/16/2023]
Abstract
INTRODUCTION The global sequence of the pathogenesis of preterm labor remains unclear. This study aimed to compare amniotic fluid concentrations of extracellular matrix-related proteins (procollagen, osteopontin and IL-33), and of cytokines (IL-19, IL-6, IL-20, TNFα, TGFβ, and IL-1β) in asymptomatic women with and without subsequent spontaneous preterm delivery. MATERIAL AND METHODS We used amniotic fluid samples of singleton pregnancy, collected by amniocentesis between 16 and 20 weeks' gestation, without stigmata of infection (i.e., all amniotic fluid samples were tested with broad-range 16 S rDNA PCR to distinguish samples with evidence of past bacterial infection from sterile ones), during a randomized, double-blind, placebo-controlled trial to perform a nested case-control laboratory study. Cases were women with a spontaneous delivery before 37 weeks of gestation (preterm group). Controls were women who gave birth at or after 39 weeks (full term group). Amniotic fluid concentrations of the extracellular matrix-related proteins and cytokines measured by immunoassays were compared for two study groups. CLINICALTRIALS gov: NCT00718705. RESULTS Between July 2008 and July 2011, in 12 maternal-fetal medicine centers in France, 166 women with available PCR-negative amniotic fluid samples were retained for the analysis. Concentrations of procollagen, osteopontin, IL-19, IL-6, IL-20, IL-33, TNFα, TGFβ, and IL-1β were compared between the 37 who gave birth preterm and the 129 women with full-term delivery. Amniotic fluid levels of procollagen, osteopontin, IL-19, IL-33, and TNFα were significantly higher in the preterm than the full-term group. IL-6, IL-20, TGFβ, and IL-1β levels did not differ between the groups. CONCLUSIONS In amniotic fluid 16 S rDNA PCR negative samples obtained during second-trimester amniocentesis, extracellular matrix-related protein concentrations (procollagen, osteopontin and IL-33), together with IL-19 and TNFα, were observed higher at this time in cases of later spontaneous preterm birth.

Perinatal survival among very preterm singletons born after detection of early-onset fetal growth restriction with or without maternal hypertensive disorders: A population-based study in France. Eur J Obstet Gynecol Reprod Biol 2023; 282:43-49. [PMID: 36634405 DOI: 10.1016/j.ejogrb.2023.01.004] [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: 07/11/2022] [Revised: 12/28/2022] [Accepted: 01/03/2023] [Indexed: 01/06/2023]
Abstract
OBJECTIVE To investigate the management and survival of very preterm singletons born because of fetal growth restriction (FGR) with or without maternal hypertensive disorders in France. STUDY DESIGN From a population-based cohort of very preterm births between 22 and 31 weeks in France in 2011, the study population included all non-anomalous singleton pregnancies delivered because of detected FGR with or without maternal hypertensive disorders. Antenatal detection of FGR was defined as an estimated fetal weight <10th percentile with or without fetal Doppler abnormalities or growth arrest. All fetuses were alive at the time of detection of FGR. Indicators of active perinatal management (antenatal steroids, pre-labor cesarean and birth in level 3 maternity unit) and fetal/neonatal outcomes (terminations of pregnancy (TOP), stillbirths, neonatal deaths and survival to discharge) were compared by gestational age between FGR associated with maternal hypertensive disorders and isolated FGR. RESULTS Overall, 398 pregnancies delivered before 32 weeks for FGR associated with hypertensive disorders and 234 for isolated FGR. Active perinatal care was rare before 26 weeks in both groups and about one in five cases associated with maternal hypertensive disorders received steroids and was born by prelabor cesarean compared to none for isolated FGR. Before 25 weeks of gestation age, more pregnancies resulted in TOP when FGR was associated with hypertensive disorders compared to isolated FGR (respectively, 76.2 % vs 28.0 % at 22-23 weeks, P = 0.002 and 57.9 % vs 21.1 % at 24 weeks, P = 0.028) whereas stillbirths were more common among isolated FGR (respectively, 23.8 % vs 72.0 % at 22-23 weeks, P = 0.002 and 36.8 % vs 73.7 % at 24 weeks, P = 0.030). Survival to discharge was higher at any gestational age when the cause of birth was FGR associated with hypertensive disorders compared to isolated FGR. CONCLUSION The management and pregnancy outcomes differed when FGR was associated with maternal hypertensive disorders or isolated. The proportion of TOP was higher when FGR was associated with hypertensive disorders and the proportion of stillbirths was higher in isolated FGR.

Implementation of glucose 5% supplementation protocol to reduce the duration of labor among women with cervical ripening by prostaglandins: The GLUCOSHORT before-and-after study. J Gynecol Obstet Hum Reprod 2023; 52:102558. [PMID: 36806716 DOI: 10.1016/j.jogoh.2023.102558] [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: 11/30/2022] [Revised: 02/07/2023] [Accepted: 02/16/2023] [Indexed: 02/22/2023]
Abstract
INTRODUCTION Previous publications have shown that glucose supplementation could reduce labor duration in women with induction of labor with a favorable cervix but none have shown it for women with an unfavorable cervix. The purpose of our study was to assess the impact on labor duration of a protocol of glucose supplementation used for induction of labor in women with an unfavorable cervix. MATERIAL AND METHODS The protocol implemented in November 2017 added glucose supplementation by 5% dextrose at 125 mL/h to Ringer lactate for women with an unfavorable cervix with labor induced with dinoprostone gel. The study included women who underwent this protocol with a singleton, term, cephalic fetus from June 2017 through April 2018. The primary outcome was the labor duration. The secondary outcomes were mode of delivery, postpartum hemorrhage rate, neonatal outcomes, and durations other stage of labor. These outcomes were compared between the pre-intervention (from June 1 to October 31, 2017) and post-intervention (from December 1, 2017 to April 30, 2018) periods. RESULTS The pre-intervention period included 116 women, and the post-intervention period 123. The characteristics of women and the induction of labor were similar in the two periods. The median duration from induction to delivery was not significantly different between the two periods (13.2 h, IQR 9.1-18.6 versus 13.6 h IQR 9.3-18.3, P=.67). The secondary outcomes did not differ significantly between the two groups. DISCUSSION Glucose supplementation administered to women with an unfavorable cervix undergoing induction does not appear to reduce the induction-delivery duration.

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.

Abstract
OBJECTIVE To identify risk factors for moderate or severe hypoxic-ischemic encephalopathy (HIE), or neonatal death in clinical placental abruption. MATERIAL AND METHODS A nested case-control study within a cohort of singleton pregnancies complicated by placental abruption with a live born infant at two academic reference centers in France, from 2006 to 2019. Cases were patients who gave birth to an infant with moderate or severe HIE or death within 28 days (HIE/death group), and controls were patients whose infant did not have any of these outcomes (no-HIE group). Independent risk factors were identified by logistic regression. Binary decision tree discriminant (CART) analysis was performed to define high-risk subgroups of HIE or death. RESULTS Among 152 patients, the infants of 44 (29%) had HIE or death. Out-of-hospital placental abruption and fetal bradycardia at admission were more frequent in cases than in controls: 39 (89%) vs 61 (56%), p < .01 and 24 (59%) vs 19 (18%), p < .01, respectively. In multivariate analysis, out-of-hospital placental abruption (aOR, 7.05; 95% CI, 1.94-25.66) and bradycardia at admission (aOR, 8.60; 95% CI, 2.51-29.42) were independently associated with an increased risk of HIE or death. The combination of out-of-hospital placental abruption and bradycardia was the highest risk situation associated with HIE or death (67%). The decision-to-delivery interval was 15 [12-20] minutes among cases. CONCLUSION Out-of-hospital placental abruption combined with bradycardia at admission was associated with a major risk of moderate or severe HIE or death. An optimal decision-to-delivery interval does not guarantee the absence of an adverse neonatal outcome.

Abstract
OBJECTIVE To assess the association between gestational age at delivery and postpartum severe acute maternal morbidity (SAMM) in twin pregnancies. METHODS Secondary analysis of the JUMODA cohort, a national, prospective, population-based study of twin pregnancies in France. We excluded women with delivery before 32 weeks of pregnancy, with a fetal death or medical termination, with antepartum SAMM, or with antepartum conditions responsible for postpartum SAMM. The primary outcome was a composite of postpartum SAMM. We assessed the association between gestational age at delivery and SAMM by using multivariable multilevel modified Poisson regression modeling. RESULTS Among the 7713 women included, 410 (5.3%) developed postpartum SAMM. Compared with the reference category of 37 weeks of pregnancy, the risk of postpartum SAMM was significantly lower for all categories of earlier gestational age at delivery (from an adjusted relative risk [RR] of 0.34, 95% confidence interval [CI] 0.17-0.68 at 32 weeks to an adjusted RR of 0.71, 95% CI 0.54-0.94 at 36 weeks), and did not differ for later gestational ages. CONCLUSION In twin pregnancies, compared with delivery at 37 weeks of pregnancy, delivery at earlier gestational ages was associated with a lower risk of postpartum SAMM. Continuing pregnancy beyond 37 weeks of pregnancy is not associated with an increased risk of postpartum SAMM.

Abstract
OBJECTIVE To determine whether birth outside a level-3 centre (outborn) is associated with a difference in the combined outcome of mortality or moderate-to-severe neurological impairment at 5.5 years of age compared with birth in a level-3 centre (inborn) when antenatal steroids and gestational age (GA) are accounted for. DESIGN Individual matched study nested within a prospective cohort. Each outborn infant was matched using GA and antenatal steroids with a maximum of four inborns. Conditional logistic regression was used to calculate ORs before being adjusted using maternal and birth characteristics. Analyses were carried out after multiple imputation for missing data. SETTING EPIPAGE-2 French national prospective cohort including births up to 34 weeks GA inclusive. PATIENTS Outborn and inborn control infants selected between 24 and 31 weeks GA were followed in the neonatal period and to 2 and 5.5 years. 3335 infants were eligible of whom all 498 outborns and 1235 inborn infants were included-equivalent to 2.5 inborns for each outborn. MAIN OUTCOME MEASURE Survival without moderate-to-severe neurodevelopmental impairment at 5.5 years. RESULTS Chorioamnionitis, pre-eclampsia, caesarian birth and small-for-dates were more frequent among inborns, and spontaneous labour and antepartum haemorrhage among outborns. There was no difference in the main outcome measure at 5.5 years of age (adjusted OR 1.09, 95% CI 0.82 to 1.44); sensitivity analyses suggested improved outcomes at lower GAs for inborns. CONCLUSION In this GA and steroid matched cohort, there was no difference in survival without moderate-to-severe neurodevelopmental impairment to 5.5 years of age between inborn and outborn very preterm children. This suggests steroids might be important in determining outcomes.

Risk of preeclampsia in patients with symptomatic COVID-19 infection. J Gynecol Obstet Hum Reprod 2022; 51:102459.

Abstract
Objectives Recent studies suggest an association between COVID-19 infection during pregnancy and preeclampsia. Nonetheless, these studies are subject to numerous biases. We compared the onset of preeclampsia in a group with symptomatic COVID-19 during pregnancy to that in a group whose non-exposure to the virus was certain, in a center where pregnancy management was identical in both groups. Study Design This was a single-center study comparing exposed and unexposed patients. The exposed group included pregnant women with symptomatic COVID-19 infection (diagnosed by RT-PCR or CT scan), who gave birth between March and December, 2020. The unexposed group included pregnant women who gave birth between March and December, 2019. Only cases of preeclampsia that occurred after COVID-19 infection were considered. A multivariate analysis was performed to study the existence of an association between COVID-19 and preeclampsia. A sensitivity analysis was performed among nulliparous patients. Results The frequency of preeclampsia was 3.2% (3/93) in the exposed group, versus 2.2% (4/186) in the unexposed group (P = 0.58). Among the nulliparous patients, the frequency of preeclampsia was 4.9% (2/41) in the exposed group versus 0.9% (1/106) in the unexposed group (P = 0.13). The association between COVID-19 and preeclampsia was not significant after multivariate analysis (OR 3.12, 95% CI 0.39-24.6). Conclusion Symptomatic COVID-19 infection during pregnancy does not appear to increase the risk of preeclampsia strongly, although the size of our sample prevents us from reaching a conclusion about a low or moderate risk. It therefore does not appear necessary to reinforce preeclampsia screening in patients with symptomatic COVID-19 infection during pregnancy.

Abstract
INTRODUCTION The objective of this study was to assess the performance of ultrasound and magnetic resonance imaging (MRI) features in helping to classify the type of placenta accreta spectrum (PAS; accreta/increta vs percreta), alone or combined in a predictive score. MATERIAL AND METHODS We conducted a retrospective study in 82 pregnant women with PAS who underwent ultrasound and MRI examination of the pelvis before delivery (from an initial cohort of 185 women with PAS). We estimated the sensitivity, specificity and accuracy of MRI and ultrasound in the diagnosis of the type of PAS. We analyzed cesarean and imaging features using univariable logistic regression analysis. We constructed a nomogram to predict the risk of placenta percreta and validated it with bootstrap resampling, then used receiver operating characteristic curves to assess the performance of the model in distinguishing between placenta percreta and placenta accreta/increta. RESULTS Among the 82 patients, 29 (35%) had placenta accreta/increta and 53 (65%) had placenta percreta. The best features to discriminate between placenta accreta/increta and placenta percreta with ultrasound were increased vascularization at the uterine serosa-bladder wall interface (odds ratio [OR] 7.93; 95% confidence interval [CI] 2.78-24.99; p < 0.01) and the number of lacunae without a hyperechogenic halo (OR 1.36; 95% CI 1.14-1.67; p = 0.012). Concerning MRI markers, heterogeneous placenta (OR 12.89; 95% CI 3.05-89.16; p = 0.002), dark intraplacental bands (OR 12.89; 95% CI 3.05-89.16; p = 0.002) and bladder wall interruption (OR 15.89; 95% CI 4.78-73.33; p < 0.001) had a higher OR in discriminating placenta accreta/increta from placenta percreta. The nomogram yielded areas under the curve of 0.841 (95% CI 0.754-0.927) and 0.856 (95% CI 0.767-0.945), after bootstrap resampling, for the accurate prediction of placenta percreta. CONCLUSIONS The nomogram we developed to predict the risk of placenta percreta among patients with PAS had good discriminative capabilities. This performance and its impact on maternal morbidity should be confirmed by future prospective studies.

Abstract
Background The infant mortality rate (IMR) serves as a key indicator of population health. Methods We used data from the French National Institute of Statistics and Economic Studies on births and deaths during the first year of life from 2001 to 2019 to calculate IMR aggregated by month. We ran joinpoint regressions to identify inflection points and assess the linear trend of each segment. Exploratory analyses were performed for overall IMR, as well as by age at death subgroups (early neonatal [D0-D6], late neonatal [D7-27], and post-neonatal [D28-364]), and by sex. We performed sensitivity analyses by excluding deaths at D0 and using other time-series modeling strategies. Results Over the 19-year study period, 53,077 infant deaths occurred, for an average IMR of 3·63/1000 (4·00 in male, 3·25 in female); 24·4% of these deaths occurred during the first day of life and 47·8% during the early neonatal period. Joinpoint analysis identified two inflection points in 2005 and 2012. The IMR decreased sharply from 2001 to 2005 (slope: -0·0167 deaths/1000 live births/month; 95%CI: -0·0219 to -0·0116) and then decreased slowly between 2005 and 2012 (slope: -0·0041; 95%CI: -0·0065 to -0·0016). From 2012 onwards, a significant increase in IMR was observed (slope: 0·0033; 95%CI: 0·0011 to 0·0056). Subgroup analyses indicated that these trends were driven notably by an increase in the early neonatal period. Sensitivity analyses provided consistent results. Interpretation The recent historic increase in IMR since 2012 in France should prompt urgent in-depth investigation to understand the causes and prepare corrective actions.

Nulliparous women with an unfavourable cervix at 41 weeks: Which women go into spontaneous labor during the expectant period? Eur J Obstet Gynecol Reprod Biol 2021; 269:35-40. [PMID: 34968872 DOI: 10.1016/j.ejogrb.2021.12.018] [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: 08/07/2021] [Revised: 11/14/2021] [Accepted: 12/11/2021] [Indexed: 11/28/2022]
Abstract
CONTEXT After 41 weeks, the labor induction term varies according to countries and obstetrical teams. The French recommendations are not to exceed 41 weeks 6 days. However, there are no data on the percentage of nulliparous women with an unfavorable cervix at 41 weeks going into spontaneous labor within five or six days. OBJECTIVE The objective was to establish the rate of spontaneous labor within five days amongst nulliparous women with an unfavorable cervix at 41 weeks, and to identify the maternal and obstetrical factors associated with this spontaneous labor. MATERIALS AND METHODS Retrospective study in a University Hospital Maternity between January 1st and December 31st 2017. All nulliparous women with a cephalic fetal presentation and unfavorable cervix at 41 weeks (Bishop ≤ 3) were included. The maximum term for induced labor was set at 41 weeks 5 days. The population was divided into two groups: spontaneous labor and induced labor (induction between 41 weeks and 41 weeks 4 days for medical indications or maternal wish and induction at 41 weeks 5 days for full term). The maternal and obstetrical characteristics of the two groups at 41 weeks were compared as well as the maternal and neonatal outcomes. RESULTS The rate of spontaneous labor among the 269 women included was 38.3% (n = 103/269). At 41 weeks, the presence of painful uterine contractions and a Bishop score of 3 were associated with spontaneous labor within five days (p < 0.01). The Bishop score criteria most associated with spontaneous labor were cervical dilation and fetal station. The cesarean delivery rate was 20.4% in the group of women with spontaneous labor versus 41.0% in the group of induced labor (p < 0.01). There were no differences between the two groups in terms of neonatal outcome. CONCLUSION Among nulliparous women with an unfavorable cervix at 41 weeks, almost 40 % will have a spontaneous onset of labor within five days. The only factors found to be associated with this onset of labor are the presence of painful uterine contractions and a higher Bishop score at 41 weeks.

Abstract
INTRODUCTION The "en caul" technique, i.e. delivery with intact membranes, may reduce the risk of obstetric trauma in vaginal breech delivery of extreme preterm infants. We aimed at comparing perinatal mortality and morbidity among extremely preterm breech vaginal deliveries between infants delivered "en caul" and those with "ruptured membranes". MATERIAL AND METHODS We performed a fourteen-year retrospective study in a tertiary university center. All vaginal deliveries of singleton breech live infants with an antenatal decision of active resuscitation between 24 weeks and 27+6 weeks were included. Perinatal outcomes were compared between the "en caul" group, with intact membranes at the onset of pushing efforts and the "ruptured membranes" group, with ruptured membranes at the onset of pushing efforts. The primary outcome was perinatal mortality defined by intrapartum or neonatal death. The secondary outcomes were fetal extraction difficulties, arterial pH and 5 min Apgar score. RESULTS We included 52 infants in the "en caul" group and 71 in the "ruptured membranes" group. The perinatal mortality rate did not differ between the two groups (19.2% in the "en caul" group versus 28.2% in the "ruptured membranes" group, p = 0.25). The mean arterial pH at birth was higher in the « en caul » group (7.32 ± 0.1 vs 7.24 ± 0.1, p = 0.001). There were no differences between the groups for fetal extraction difficulties, especially fetal head entrapment (9.6% versus 9.9%). CONCLUSION Even though the "en caul" technique does not seem to decrease the perinatal mortality rate, it remains a simple technique, which could improve neonatal morbidity.

Comparison of the performance of estimated fetal weight charts for the detection of small- and large-for-gestational age newborns with adverse outcomes: a French population-based study. BJOG 2021; 129:938-948.

Abstract
OBJECTIVE To compare the performance of estimated fetal weight (EFW) charts at the third trimester ultrasound for detecting small- and large-for-gestational age (SGA/LGA) newborns with adverse outcomes. DESIGN Nationally representative observational study. SETTING French maternity units in 2016. POPULATION 9940 singleton live births with an ultrasound between 30 and 35 weeks of gestation. METHODS We compared three prescriptive charts (INTERGROWTH-21st, World Health Organization (WHO), Eunice Kennedy Shriver National Institute of Child Health and Human Development [NICHD]), four descriptive charts (Hadlock, Fetal Medicine Foundation, two French charts) and a French customised growth model (Epopé). MAIN OUTCOME MEASURES SGA and LGA (birthweights <10th and >90th percentiles) associated with adverse outcomes (low Apgar score, delivery-room resuscitation, neonatal unit admission). RESULTS 2.1% and 1.1% of infants had SGA and LGA and adverse outcomes, respectively. The sensitivity and specificity for detecting these infants with an EFW <10th and >90th percentile varied from 29-65% and 84-96% for descriptive charts versus 27-60% and 83-96% for prescriptive charts. WHO and French charts were closest to the EFW distribution, yielding a balance between sensitivity and specificity for SGA and LGA births. INTERGROWTH-21st and Epopé had low sensitivity for SGA with high sensitivity for LGA. Areas under the receiving operator characteristics curve ranged from 0.62 to 0.74, showing low to moderate predictive ability, and diagnostic odds ratios varied from 7 to 16. CONCLUSION Marked differences in the performance of descriptive as well as prescriptive EFW charts highlight the importance of evaluating them for their ability to detect high-risk fetuses. TWEETABLE ABSTRACT Choice of growth chart strongly affected identification of high-risk fetuses at the third trimester ultrasound.

Term prelabor rupture of the membranes with unfavorable cervix: Frequency and factors associated with spontaneous onset of labor after two days of expectant management. J Gynecol Obstet Hum Reprod 2021; 51:102270.

Abstract
INTRODUCTION In case of term prelabor rupture of membranes (PROM), expectant management is a reasonable option. We aimed at assessing the frequency of spontaneous onset of labor after two days of term PROM and its associated factors. MATERIAL AND METHODS Women delivering at a tertiary center of a singleton in cephalic presentation, after a term PROM with an unfavorable cervix and with an expectant management period of at least two days were included during a 2-year period. Women were excluded in case of induction of labor before or at day 2(D2) or of spontaneous labor before D2. The frequency of spontaneous labor was assessed, then maternal characteristics at admission and at D2 were compared between women with a spontaneous onset of labor before D3, and women with an induced labor at D3. The maternal and neonatal outcomes were compared between the two groups. The factors associated with spontaneous labor in univariate analysis were tested in multivariable analysis. RESULTS Among the 11 608 women delivering at term, 933(8.4%) had a term PROM. Among them, 191 had an unfavorable cervix after D2 including 86(45%) women with a spontaneous labor onset between D2 and D3 and 105(55%) induced at D3. Maternal age below 35 years (reference ≥35years) and Bishop score of 3,4 and 5,6 at D2 (reference score 0-2) were significantly associated with spontaneous onset of labor, respectively aOR 2.62; 95%CI[1.26-5.45], aOR 2.38; 95%CI[1.18-4.78] and aOR 10.16; 95%CI[3.67-28.15]. DISCUSSION In women with a term PROM and an unfavorable cervix, spontaneous labor still occurs in nearly half of women undelivered after two days of expectant management.

Abstract
BACKGROUND Negative childbirth experience may affect mother wellbeing and health. However, it is rarely evaluated in studies comparing methods of induction of labor (IoL). AIM To compare women's experience of IoL according to the method, considering the mediating role of interventions and complications of delivery. METHODS We used data from the MEDIP prospective population-based cohort, including all women with IoL during one month in seven French perinatal networks. The experience of IoL, assessed at 2 months postpartum, was first compared between cervical ripening and oxytocin, and secondarily between different cervical ripening methods. Mediation analyses were used to measure the direct and indirect effects of cervical ripening on maternal experience, through delivery with interventions or complications. FINDINGS The response rate was 47.8% (n = 1453/3042). Compared with oxytocin (n = 541), cervical ripening (n = 910) was associated less often with feelings that labor went 'as expected' (adjusted risk ratio for the direct effect 0.78, 95%CI [0.70-0.88]), length of labor was 'acceptable' (0.76[0.71-0.82]), 'vaginal discomfort' was absent (0.77[0.69-0.85]) and with lower global satisfaction (0.90[0.84-0.96]). Interventions and complications mediated between 6 and 35% of the total effect of cervical ripening on maternal experience. Compared to the dinoprostone insert, maternal experience was not significantly different with the other prostaglandins. The balloon catheter was associated with less pain. DISCUSSION Cervical ripening was associated with a less positive experience of childbirth, whatever the method, only partly explained by interventions and complications of delivery. CONCLUSION Counselling and support of women requiring cervical ripening might be enhanced to improve the experience of IoL.

Abstract
OBJECTIVE To evaluate the respiratory outcome in children with congenital heart disease (CHD), considering recent management procedures and the CHD pathophysiology. DESIGN AND SETTING Clinical and functional respiratory outcome were evaluated in 8-year-old children with isolated CHD followed up from birth in the prospective population-based EPICARD cohort. PATIENTS Children were assigned to two groups, based on the pathophysiology of the CHD: CHDs with left-to-right shunt (n = 212) and CHDs with right outflow tract obstruction (n = 113). RESULTS Current wheezing episodes were observed in 15% of the children with isolated CHD and left-to-right shunt, and 11% of the children with isolated CHD and right outflow tract obstruction (not significant). Total lung capacity (TLC) was the only respiratory function parameter that significantly differed between the two groups. It was lower in children with left-to-right shunt (88.72 ± 0.65% predicted) than in those with right outflow tract obstruction (91.84 ± 0.96, p = 0.006). In multivariate analysis, CHD with left-to-right shunt (coeff. [95% CI]: -3.17 [-5.45; -0.89]) and surgery before the age of 2 months (-6.52 [-10.90; -2.15]) were identified as independent factors associated with significantly lower TLC values. CONCLUSION Lower TLC remains a long-term complication in CHD, particularly in cases with left-to-right shunt and in patients requiring early repair. These findings suggest that an increase in pulmonary blood flow may directly impair lung development.

Abstract
Abstract
Study question
How to assess the different adenomyosis phenotype before and after pregnancy on magnetic resonance imaging according to stringent validated criteria ?
Summary answer
Diffuse adenomyosis increases significantly after pregnancy while the rate of focal adenomyosis and the mean volume of focal adenomyosis lesions decrease significantly after pregnancy.
What is known already
Adenomyosis and endometriosis are benign hormone-dependent disorders associated with pelvic pain, dysmenorrhea and/or infertility. The natural course of adenomyosis and endometriosis is still unclear, particularly during pregnancy. Pregnancy is considered to have a positive impact on endometriosis. Several studies regarding the impact of adenomyosis on pregnancy are available. Adenomyosis can cause fertility disorders, miscarriage, preterm birth. However, available data evaluating the effect of pregnancy on adenomyosis are lacking.
Study design, size, duration
Between January 1st 2010 and September 30th 2020, 139 patients were followed in our referral care center (Gynecology department of Port-Royal Hospital, Paris) for symptomatic adenomyosis and or endometriosis. For each of them, a magnetic resonance imaging were performed before and after pregnancy. The data based on magnetic resonance imaging, pre- and post-pregnancy, were analyzed in a single retrospective study.
Participants/materials, setting, methods
Patients had to be over 18 years old, to be pregnant and to be followed for symptomatic adenomyosis or endometriosis without any previous surgery. Each pelvic magnetic resonance imaging were performed by a single experienced radiologist. The protocol was identical on a 1.5 T magnetic resonance imaging machine based on validated criteria. The rate of diffuse and focal adenomyosis, the volume of focal adenomyosis lesions and the thickness of maximal junctional zone were reported.
Main results and the role of chance
The mean age of patients was 34.6 ± 3.4 years old, 83 (59.7%) of patients underwent assisted reproductive technology to be pregnant. The mean time interval between the MRI and the delivery was 55.2 months and the mean time interval between the delivery and the MRI was 32.2 months. Before pregnancy, there was 96 (69.1%) patients with adenomyosis, all phenotype combined versus 111 (79.9%) after pregnancy (p = 0.04) on magnetic resonance imaging. The rate of diffuse adenomyosis increased significantly on magnetic resonance imaging after pregnancy compared to before pregnancy (n = 22 (15.8%) vs n = 41 (29.5%), p = 0.01). The thickness of junctional zone maximal was significantly higher after pregnancy (8.0 mm ± 5.1 vs 12.0 mm ± 4.8, p < 0.01). The rate of focal adenomyosis (n = 55 (39.6) vs n = 34 (24.5), p = 0.01) as well as the volume of focal adenomyosis lesions (6.7 mm3 2.5± vs 6.4 mm3 ± 2.3, p < 0.01) decreased significantly after pregnancy on magnetic resonance imaging.
Limitations, reasons for caution
This single-center study was conducted in a referral center whom patients presented more severe forms of adenomyosis, which could have affected the external validity of this study. The mean time interval between delivery and MRI was 32.2 month which implies a short follow up period to observe long term outcomes.
Wider implications of the findings
The hypothesis that a specific hormonal environment during pregnancy may imply a positively impact of the evolution of focal adenomyosis is raised by this study. The evolution of focal adenomyosis after pregnancy is similar to the evolution of endometriosis lesions volume that support shared etiopathogenic mechanisms between the two entities.
