Perinatal outcome after planned vaginal delivery in monochorionic compared with dichorionic twin pregnancy.

OBJECTIVE: To assess, according to chorionicity, the perinatal outcome of twin pregnancy in which vaginal delivery is planned. METHODS: JUMODA (JUmeaux MODe d'Accouchement) was a national prospective population-based cohort study of twin pregnancies, delivered in 176 maternity units in France, from February 2014 to March 2015. In this planned secondary analysis, we assessed, according to chorionicity, the perinatal outcome of twin pregnancies, in which vaginal delivery was planned, that delivered at or after 32 weeks of gestation with the first twin in cephalic presentation. In order to select a population with well-recognized indications for planned vaginal delivery, we applied the same exclusion criteria as those in the Twin Birth Study, an international randomized trial. Monochorionic twin pregnancies with twin-to-twin transfusion syndrome or twin anemia-polycythemia sequence were defined as complicated and were excluded. The primary outcome was a composite of intrapartum mortality and neonatal morbidity and mortality. Multivariable logistic regression models were used to control for potential confounders. Subgroup analyses were conducted according to birth order (first or second twin) and gestational age at delivery (< 37 or ≥ 37 weeks of gestation). RESULTS: Among 3873 twin pregnancies, in which vaginal delivery was planned, that delivered at ≥ 32 weeks' gestation with the first twin in cephalic presentation, meeting the inclusion criteria of the Twin Birth Study, 729 (18.8%) were uncomplicated monochorionic twin pregnancies and 3144 (81.2%) were dichorionic twin pregnancies. The rate of composite intrapartum mortality and neonatal morbidity and mortality did not differ between uncomplicated monochorionic (27/1458 (1.9%)) and dichorionic (107/6288 (1.7%)) twin pregnancies when adjusting for conception by assisted reproductive technologies (adjusted relative risk, 1.07 (95% CI, 0.66-1.75)). No significant difference in the primary outcome was found between the groups on subgroup analyses according to birth order and gestational age at delivery. CONCLUSION: When vaginal delivery is planned, and delivery occurs at ≥ 32 weeks of gestation with the first twin in cephalic presentation, uncomplicated monochorionic twin pregnancy is not associated with a higher rate of composite intrapartum mortality and neonatal morbidity and mortality compared with dichorionic twin pregnancy. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Prenatal stomach position predicts gastrointestinal morbidity at 2 years in fetuses with left-sided congenital diaphragmatic hernia.

OBJECTIVE: The long-term morbidity associated with isolated left-sided congenital diaphragmatic hernia (CDH) has been described previously. However, antenatal criteria impacting gastrointestinal morbidity (GIM) are not yet defined. The objective of this study was to evaluate the effect of fetal stomach position on the risk of GIM at 2 years of age in children with left-sided CDH. METHODS: This was a retrospective, observational multicenter cohort study of data obtained from January 2010 to January 2014, that included patients whose fetus had isolated left-sided CDH, with or without fetal endoscopic tracheal occlusion (FETO). Prenatal maternal, fetal and pediatric data were collected. Fetal stomach position was evaluated a posteriori by two observers, using ultrasound images at the level of the four-chamber view of the heart that had been obtained to calculate the observed-to-expected lung-area-to-head-circumference ratio (O/E-LHR). Fetal stomach position was graded as follows: Grade 1, stomach not visualized; Grade 2, stomach visualized anteriorly, next to the apex of the heart, with no structure in between the stomach and the sternum; Grade 3, stomach visualized alongside the left ventricle of the heart, and abdominal structures anteriorly; or Grade 4, as Grade 3 but with stomach posterior to the level of the atrioventricular heart valves. The primary outcome was GIM at 2 years of age, assessed in a composite manner, including the occurrence of gastroesophageal reflux disease, need for gastrostomy, duration of parenteral and enteral nutrition and persistence of oral aversion. Regression analysis was performed in order to investigate the effect of O/E-LHR, stomach position and FETO on various GIM outcome variables. RESULTS: Forty-seven patients with fetal left-sided CDH were included in the analysis. Thirteen (27.7%) infants did not meet the criterion of exclusive oral feeding at 2 years of age. Fetal stomach position grade was associated significantly and independently with the duration of parenteral nutrition (odds ratio (OR), 19.86; P = 0.031) and persistence of oral aversion at 2 years (OR, 3.40; P = 0.006). On multivariate analysis, O/E-LHR was predictive of the need for prosthetic patch repair, but not for GIM. FETO did not seem to affect the risk of GIM at 2 years. CONCLUSION: In isolated left-sided CDH, fetal stomach position is the only factor that is predictive of GIM at 2 years of age. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Optimal gestational age at delivery in isolated left-sided congenital diaphragmatic hernia.

OBJECTIVE: To evaluate the morbidity and mortality of neonates with left-sided isolated congenital diaphragmatic hernia (CDH) according to gestational age at delivery. METHODS: This was a retrospective study of fetuses diagnosed prenatally with isolated left-sided CDH that were delivered in the University Hospitals of Antoine Béclère-Bicêtre and Leuven between 1 January 2010 and 31 December 2018. The Kaplan-Meier method was used to calculate cumulative survival at 28 days after birth according to gestational age at delivery. The association between gestational age at delivery, as a continuous variable, and survival at 28 days was modeled using a fractional polynomial. Adjustment for position of the liver, management center and mode of delivery was performed. The association was also evaluated according to the severity of CDH, as defined by the observed-to-expected lung-to-head ratio (o/e-LHR), which was classified as severe (o/e-LHR < 25%), moderate (o/e-LHR between 25% and 45%) or mild (o/e-LHR > 45%). RESULTS: We included 213 fetuses with isolated left-sided CDH, with a median gestational age at delivery of 38 + 2 weeks (interquartile range, 37 + 0 to 39 + 1 weeks). The survival rates at 28 days and at 6 months were 66.7% (142/213) and 64.3% (137/213), respectively. Kaplan-Meier analysis showed a higher survival rate at 28 days for babies delivered between 37 + 0 and 38 + 6 weeks than for those delivered at or after 39 + 0 weeks (log-rank test, P < 0.001). In the subgroup of moderate CDH, the 28-day survival rate was significantly higher in newborns delivered between 37 + 0 and 38 + 6 weeks than in those delivered at or after 39 + 0 weeks (81.5% vs 61.5%; P = 0.03), and this was also the case for survival rate at 6 months. In the subgroup with moderate CDH, 28-day survival significantly increased with advancing gestational age at birth up to about 38-39 weeks (P = 0.005), and significantly decreased from 39 weeks onwards. CONCLUSION: Delivery between 37 + 0 and 38 + 6 weeks' gestation is associated with a higher survival rate at 28 days in neonates with isolated left-sided CDH and moderate lung hypoplasia, independently of intrathoracic liver, management center and mode of delivery. © 2020 International Society of Ultrasound in Obstetrics and Gynecology.

Do obstetricians apply the national guidelines? A vignette-based study assessing practices for the prevention of preterm birth.

OBJECTIVE: To describe spontaneous preterm birth prevention practices self-reported before and after the dissemination of relevant guidelines, and to identify personal and organisational factors associated with adherence. DESIGN: A repeated cross-sectional vignette-based survey study. SETTING: French obstetricians. POPULATION: French obstetricians practicing in public or private maternity units. METHODS: Before and after the dissemination of the 2017 French guidelines on the prevention of spontaneous preterm birth, participants were asked to complete a web-based self-administered questionnaire based on two clinical vignettes. Vignette 1 focused on respondents' attitudes towards strict bed rest, cerclage, and progesterone treatment for women with a short cervix in mid-trimester; vignette 2 focused on attitudes towards strict bed rest and maintenance tocolysis after successful tocolysis for preterm labour. A mixed quantitative and qualitative analysis was conducted. MAIN OUTCOME MEASURES: Non-adherence to guidelines for the prevention of spontaneous preterm birth in responses to each vignette. RESULTS: We obtained complete responses from 286 obstetricians before and 282 obstetricians after guideline dissemination, including 145 obstetricians participating in both. After dissemination, 51.4% of obstetricians self-reported non-adherent practices for vignette 1 and 22.3% of obstetricians self-reported non-adherent practices for vignette 2. No improvement was observed after dissemination. The quantitative analysis identified factors associated with non-adherence, including older age and practice in non-university or small hospitals, whereas the qualitative analysis highlighted barriers to implementation, including fear of change, habits, work overload, and lack of time. CONCLUSIONS: Adherence to guidelines was generally low, with practices unmodified by their dissemination. Improvement is required, especially regarding applicability. TWEETABLE ABSTRACT: Adherence to guidelines to prevent spontaneous preterm birth was generally low and remained unmodified after guideline dissemination.

Prognostic value of diffusion-weighted magnetic resonance imaging of brain in fetal growth restriction: results of prospective multicenter study.

OBJECTIVE: To measure prospectively apparent diffusion coefficient (ADC) values between 28 and 32 weeks of gestation in different cerebral territories of fetuses with estimated fetal weight (EFW) ≤ 5th centile, and analyze their association with adverse perinatal outcome. METHODS: This was a prospective study involving six tertiary-level perinatal centers. In the period 22 November 2016 to 11 September 2017, we included singleton, small-for-gestational-age (SGA) fetuses with EFW ≤ 5th percentile, between 28 and 32 weeks of gestation, regardless of the umbilical artery Doppler and maternal uterine artery Doppler findings. A fetal magnetic resonance imaging (MRI) examination with diffusion-weighted sequences (DWI) was performed within 14 days following inclusion and before 32 weeks. ADC values were calculated in the frontal and occipital white matter, basal ganglia and cerebellar hemispheres. An ultrasound examination was performed within 1 week prior to the MRI examination. The primary outcome was a composite measure of adverse perinatal outcome, defined as any of the following: perinatal death; admission to neonatal intensive care unit with mechanical ventilation > 48 h; necrotizing enterocolitis; Grade III-IV intraventricular hemorrhage; periventricular leukomalacia. A univariate comparison of median ADC values in all cerebral territories between fetuses with and those without adverse perinatal outcome was performed. The association between ADC values and adverse perinatal outcome was then analyzed using multilevel logistic regression models to adjust for other common prognostic factors for growth-restricted fetuses. RESULTS: MRI was performed in 64 patients, of whom five were excluded owing to fetal movement artifacts on DWI and two were excluded for termination of pregnancy with no link to fetal growth restriction (FGR). One intrauterine death occurred secondary to severe FGR. Among the 56 liveborn neonates, delivered at a mean ± SD gestational age of 33.6 ± 3.0 weeks, with a mean birth weight of 1441 ± 566 g, four neonatal deaths occurred. In addition, two neonates required prolonged mechanical ventilation, one of whom also developed necrotizing enterocolitis. Overall, therefore, seven out of 57 (12.3%) cases had an adverse perinatal outcome (95% CI, 3.8-20.8%). The ADC values in the frontal region were significantly lower in the group with adverse perinatal outcome vs those in the group with favorable outcome (mean values of both hemispheres, 1.68 vs 1.78 × 10-3 mm2 /s; P = 0.04). No significant difference in ADC values was observed between the two groups in any other cerebral territory. A cut-off value of 1.70 × 10-3 mm2 /s was associated with a sensitivity of 57% (95% CI, 18-90%), a specificity of 78% (95% CI, 63-88%), a positive predictive value of 27% (95% CI, 8-55%) and a negative predictive value of 93% (95% CI, 80-98%) for the prediction of adverse perinatal outcome. A mean frontal ADC value < 1.70 × 10-3 mm2 /s was not associated significantly with an increased risk of adverse perinatal outcome, either in the univariate analysis (P = 0.07), or when adjusting for gestational age at MRI and fetal sex (odds ratio (OR), 6.06 (95% CI, 0.9-37.1), P = 0.051) or for umbilical artery Doppler (OR, 6.08 (95% CI, 0.89-41.44)). CONCLUSION: This first prospective, multicenter, cohort study using DWI in the setting of SGA found lower ADC values in the frontal white-matter territory in fetuses with, compared with those without, adverse perinatal outcome. To determine the prognostic value of these changes, further standardized evaluation of the neurodevelopment of children born with growth restriction is required. Copyright © 2019 ISUOG.

[Diagnostic and therapeutic recommendations for sexually transmitted diseases: Genital herpes]. / Recommandations diagnostiques et thérapeutiques pour les maladies sexuellement transmissibles : herpès génital au cours de la grossesse.

TREATMENT OF THE INITIAL INFECTION OR FIRST CLINICAL EPISODE OF GENITAL HERPES: An initial infection or first clinical episode of genital herpes is treated with oral aciclovir 200mg×5/d for 5 to 10 days depending on clinical status. The recommended dosage for valaciclovir is 1g×2/d and treatment duration is identical to that for aciclovir. TREATMENT OF HERPES RECURRING DURING PREGNANCY: There are no studies of the efficacy of antiviral therapy on the symptoms of genital recurring during pregnancy. However, initial anti-viral treatment using aciclovir or valaciclovir may be given where warranted by symptoms (i.e. duration and severity of symptoms). Valaciclovir may be used instead (equivalent efficacy but better safety data for aciclovir). Valaciclovir may be given at a dosage of 1×500mg b.i.d. p.o. for 5 days. PROPHYLACTIC ANTI-VIRAL TREATMENT DURING PREGNANCY: In female patients presenting an initial infection or infection recurring during pregnancy, although there is no demonstrated benefit for prophylactic treatment in reducing the risk of neonatal herpes, anti-viral prophylaxis is recommended after 36 WA (weeks' amenorrhoea) to limit the need for Caesarean section due to herpetic lesions. The recommended antivirals are aciclovir at a dosage of 400mg t.i.d p.o. or valaciclovir at a dosage of 500mg b.i.d. p.o. until delivery.

Prognosis of isolated congenital diaphragmatic hernia using lung-area-to-head-circumference ratio: variability across centers in a national perinatal network.

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

Stomach position in prediction of survival in left-sided congenital diaphragmatic hernia with or without fetoscopic endoluminal tracheal occlusion.

OBJECTIVE: To investigate the value of fetal stomach position in predicting postnatal outcome in left-sided congenital diaphragmatic hernia (CDH) with and without fetoscopic endoluminal tracheal occlusion (FETO). METHODS: This was a retrospective review of CDH cases that were expectantly managed or treated with FETO, assessed from May 2008 to October 2013, in which we graded, on a scale of 1-4, stomach position on the four-chamber view of the heart with respect to thoracic structures. Logistic regression analysis was used to investigate the effect of management center (Paris, Brussels, Barcelona, Milan), stomach grading, observed-to-expected lung area-to-head circumference ratio (O/E-LHR), gestational age at delivery, birth weight in expectantly managed CDH, gestational ages at FETO and at removal and period of tracheal occlusion, on postnatal survival in CDH cases treated with FETO. RESULTS: We identified 67 expectantly managed CDH cases and 47 CDH cases that were treated with FETO. In expectantly managed CDH, stomach position and O/E-LHR predicted postnatal survival independently. In CDH treated with FETO, stomach position and gestational age at delivery predicted postnatal survival independently. CONCLUSION: In left-sided CDH with or without FETO, stomach position is predictive of postnatal survival.

Detailed in utero ultrasound description of 30 cases of congenital cytomegalovirus infection.

OBJECTIVES: The aim of this research was to describe precisely prenatal ultrasound (US) features in congenital cytomegalovirus (CMV) infection. METHODS: We retrospectively evaluated the US descriptions of cases of congenital CMV infection between 2004 and 2013. RESULTS: In 69 congenital CMV infections, related US abnormalities were reported in 30 cases (43.5%). There were both extracerebral and cerebral abnormalities in 16 cases, purely abnormal brain features in ten, and purely extracerebral features in two. About 19/30 cases presented extracerebral features of 11 different sorts of abnormalities, mainly hyperechogenic bowel (ten cases) and intrauterine growth retardation (nine cases). About 24/30 cases presented cerebral features of 13 different sorts, mainly brain calcifications (12 cases) and occipital horn cavity (11 cases). The main US findings in our series are not specific to CMV infection. However, a frequent finding attracted our attention: the anechogenic cavity located on the extremity of the occipital horn, a region which contains numerous proliferating and differentiating germinal cells. CONCLUSIONS: By improving knowledge of US findings linked to CMV infection, US sensitivity may be improved. Understanding why CMV leads to lesions of the occipital horn may help clarify the pathophysiology of congenital infection.

Factors affecting feasibility and quality of second-trimester ultrasound scans in obese pregnant women.

OBJECTIVES: To evaluate the feasibility of completing in one session a second-trimester ultrasound scan in obese pregnant women, to compare the quality of images obtained with those of non-obese women and to analyze factors that can improve the completion rate. METHODS: This prospective study, from 2009 to 2011, included all obese pregnant women (prepregnancy body mass index (BMI) > 30 kg/m2) who had an ultrasound examination at 20-24 weeks in our department, and a control group of pregnant women with normal BMI (20-24.9 kg/m2) who had the same examination. A single operator reviewed the standardized ultrasound images (three biometric and six to assess key anatomical features) required under French guidelines, to assess their presence, evaluate the quality of all images and score the quality of the six anatomical images. Each image was assessed according to between four and six criteria, each worth one point. We sought excellent quality, defined as the frequency of maximum points for a given image type. The factors associated with completing the scan in one session were evaluated with multivariate logistic regression. RESULTS: The obese group included 223 women and the control group 60; a complete scan in one session was achieved in 70.4% and 81.7% of these, respectively (P = 0.08). The completion rate for each image type was at least 95% in the control group and 90% in the obese group, except for diaphragm and right outflow tract images. Significant factors associated with completing the scan in the multivariate model were: having 10 additional minutes for the scan (P = 0.03), moving the fetus so that the back was in posterior or lateral position (P = 0.01), more experienced sonographer (P = 0.03) and thinner maternal abdominal wall thickness (P = 0.01). Overall, the excellence rate varied from 35% to 92% in the normal BMI group and from 18% to 58% in the obese group, and was significantly lower in the latter for all images except abdominal circumference (P = 0.26) and spine (P = 0.06). Anatomical quality scores were also significantly lower in the obese group (22.3 vs. 27.2; P = 0.001). CONCLUSION: Although ultrasound scans of obese pregnant women are feasible, image quality and global anatomical scores are significantly lower among obese than normal-weight women. However, certain simple improvements may increase fetal visualization.

A series of 238 cytomegalovirus primary infections during pregnancy: description and outcome.

OBJECTIVE: To analyze the outcome of maternal primary cytomegalovirus (CMV) infection. METHODS: Retrospective analysis of a cohort of 238 patients with maternal primary CMV infection detected at routine screening. The cases were managed with serial ultrasound (US) scans, and amniocentesis was performed in 36.1% of cases. All prenatal results were confirmed at birth. RESULTS: The average age was 31.9 (18-44) years. Patients were symptomatic in 21% of cases. The rate of intrauterine transmission was 24.9%, and it was 8.8%, 19%, 30.6%, 34.1% and 40% in the preconceptional period, the periconceptional period, and the first, second and third trimesters of pregnancy, respectively (p = 0.025). There was a significantly higher risk of US abnormalities when maternal infection occurred during the preconceptional or periconceptional period and the first trimester compared with later (p < 0.001). Because of US abnormalities, pregnancy was terminated in 18 cases at the parents' request. Three infected newborns were symptomatic; all three cases were suspected at US before birth. We did not observe any symptomatic fetal infection when maternal infection occurred after 14 weeks of gestation. A number of clinically asymptomatic cases (5.5%) developed hearing loss. CONCLUSION: The rate of materno fetal transmission is linearly correlated to the gestational age at infection. No severe case of congenital infection was observed if maternal infection occurred after 14 weeks of gestation.

[Intrahepatic cholestasis of pregnancy: French College of Obstetricians and Gynecologists guidelines for clinical practice]. / La cholestase gravidique : recommandations pour la pratique clinique du Collège national des gynécologues obstétriciens français.

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

[The cesarean procedure: Guidelines for clinical practice from the French College of Obstetricians and Gynecologists]. / La technique de la césarienne : recommandations pour la pratique clinique du Collège national des gynécologues obstétriciens français.

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.

Comparison of perinatal outcome after pre-viable preterm prelabour rupture of membranes in two centres with different rates of termination of pregnancy.

OBJECTIVE: To assess perinatal outcomes after expectant management in the case of preterm prelabour rupture of membranes (PPROM) before 25 weeks of gestation, according to the rate of termination of pregnancy (TOP). DESIGN: Retrospective comparative cohort study. POPULATION: Singleton pregnancies complicated by PPROM between 15(0/7) and 24(6/7) weeks of gestation, from January 2003 to January 2007. METHODS: Comparison of perinatal outcomes in two French tertiary care referral centres presumed to have different rates of TOP. MAIN OUTCOME MEASURE: Rates of TOP, survival and survival without major morbidity. RESULTS: A total of 113 women experienced PPROM (49 in centre A and 64 in centre B). A lower proportion of patients opted for TOP in centre A (40.8%) than in centre B (56.3%). The baseline characteristics of patients and pregnancies, and gestational age at PPROM, were not different between the two centres. Mean gestational age at delivery (28.1 versus 25.4 weeks of gestation; P < 0.01), mean latency period (45.5 versus 16.1 days; P < 0.01), mean birthweight (1295 versus 929 g; P = 0.04) and survival (46.9 versus 20.3%; P < 0.01) were significantly higher in centre A than in centre B. The percentage of neonates alive without major morbidity was also higher in centre A than in centre B (42.9 versus 20.3%; P = 0.01). CONCLUSIONS: Perinatal outcomes of pregnancies managed expectantly were not better in the centre where the TOP rate was higher. The perinatal risk of pregnancies complicated by pre-viable PPROM remains high.

[Ante- and postnatal growth charts in France - guidelines for clinical practice from the Collège national des gynécologues et obstétriciens français (CNGOF) and from the Société française de néonatologie (SFN)]. / Les courbes de croissance anté- et postnatales en France ­ recommandations pour la pratique clinique du Collège national des gynécologues et obstétriciens français (CNGOF) et de la Société française de néonatologie (SFN).

OBJECTIVE: To recommend the most appropriate biometric charts for the detection of antenatal growth abnormalities and postnatal growth surveillance. METHODS: Elaboration of specific questions and selection of experts by the organizing committee to answer these questions; analysis of the literature by experts and drafting conclusions by assigning a recommendation (strong or weak) and a quality of evidence (high, moderate, low, very low) and for each question; all these recommendations have been subject to multidisciplinary external review (obstetrician gynecologists, pediatricians). The objective for the reviewers was to verify the completeness of the literature review, to verify the levels of evidence established and the consistency and applicability of the resulting recommendations. The overall review of the literature, quality of evidence and recommendations were revised to take into consideration comments from external reviewers. RESULTS: Antenatally, it is recommended to use all WHO fetal growth charts for EFW and common ultrasound biometric measurements (strong recommendation; low quality of evidence). Indeed, in comparison with other prescriptive curves and descriptive curves, the WHO prescriptive charts show better performance for the screening of SGA (Small for Gestational Age) and LGA (Large for Gestational Age) with adequate proportions of fetuses screened at extreme percentiles in the French population. It also has the advantages of having EFW charts by sex and biometric parameters obtained from the same perspective cohort of women screened by qualified sonographers who measured the biometric parameters according to international standards. Postnatally, it is recommended to use the updated Fenton charts for the assessment of birth measurements and for growth monitoring in preterm infants (strong recommendation; moderate quality of evidence) and for the assessment of birth measurements in term newborn (expert opinion). CONCLUSION: It is recommended to use WHO fetal growth charts for antenatal growth monitoring and Fenton charts for the newborn.

[Expert consensus from the College of French Gynecologists and Obstetricians: Management of nausea and vomiting of pregnancy and hyperemesis gravidarum]. / Consensus formalisé d'experts du Collège national des gynécologues et obstétriciens français : prise en charge des nausées et vomissements gravidiques et de l'hyperémèse gravidique.

OBJECTIVE: To determine the management of patients with 1st trimester nausea and vomiting and hyperemesis gravidarum. METHODS: A panel of experts participated in a formal consensus process, including focus groups and two Delphi rounds. RESULTS: Hyperemesis gravidarum is distinguished from nausea and vomiting during pregnancy by weight loss≥5 % or signs of dehydration or a PUQE score≥7. Hospitalization is proposed when there is, at least, one of the following criteria: weight loss≥10%, one or more clinical signs of dehydration, PUQE (Pregnancy Unique Quantification of Emesis and nausea) score≥13, hypokalemia<3.0mmol/L, hyponatremia<120mmol/L, elevated serum creatinine>100µmol/L or resistance to treatment. Prenatal vitamins and iron supplementation should be stopped without stopping folic acid supplementation. Diet and lifestyle should be adjusted according to symptoms. Aromatherapy is not to be used. If the PUQE score is<6, even in the absence of proof of their benefit, ginger, pyridoxine (B6 vitamin), acupuncture or electrostimulation can be used, even in the absence of proof of benefit. It is proposed that drugs or combinations of drugs associated with the least severe and least frequent side effects should always be chosen for uses in 1st, 2nd or 3rd intention, taking into account the absence of superiority of a class over another to reduce the symptoms of nausea and vomiting of pregnancy and hypermesis gravidarum. To prevent Gayet Wernicke encephalopathy, Vitamin B1 must systematically be administered for hyperemesis gravidarum needing parenteral rehydration. Patients hospitalized for hyperemesis gravidarum should not be placed in isolation (put in the dark, confiscation of the mobile phone or ban on visits, etc.). Psychological support should be offered to all patients with hyperemesis gravidarum as well as information on patient' associations involved in supporting these women and their families. When returning home after hospitalization, care will be organized around a referring doctor. CONCLUSION: This work should contribute to improving the care of women with hyperemesis gravidarum. However, given the paucity in number and quality of the literature, researchers must invest in the field of nausea and vomiting in pregnancy, and HG to identify strategies to improve the quality of life of women with nausea and vomiting in pregnancy or hyperemesis gravidarum.

[CNGOF clinical practice guidelines: Evaluation one year after revision of the methodology]. / Recommandations pour la pratique clinique du CNGOF : évaluation un an après révision de la méthodologie.

OBJECTIVES: To evaluate the revision of methodology of the clinical practice guidelines (CPG) of the French National College of Gynecologists and Obstetricians (CNGOF). METHOD: Three CPGs were organized in 2020 on the topics of severe preeclampsia, menorrhagia, and prophylactic surgery according to AGREE II (Apraisal of Guidelines for Research & Evaluation). Questions were presented in PICO (Population, Intervention, Comparison, Outcome) format and the grading of scientific evidence was based on the GRADE (Grading of Recommendation Assessment, Development and Evaluation) method. RESULTS: All three CPGs groups adhered to this new methodology. However, the presentation of the arguments, the formulation of the recommendations and the development of the GRADE tables were heterogeneous from one group to another. A homogenization of the presentation is proposed, as well as a guide to the critical analysis of the literature to help the experts to rate the evidence. CONCLUSION: Adherence to these quality criteria should make it easier to apply the recommendations at the national level and improve international recognition of the work done by the CNGOF.

[Reprint of: Severe pre-eclampsia: guidelines for clinical practice from the French Society of anesthesiology and intensive care (SFAR) and the French College of gynaecologists and obstetricians (CNGOF)]. / Republication de : recommandations formalisées d'experts. Prise en charge de la patiente avec une pré-éclampsie sévère­RFE communes Société française d'anesthésie-réanimation (SFAR)­Collège national des gynécologues et obstétriciens français (CGNOF).

OBJECTIVE: To provide national guidelines for the management of women with severe preeclampsia. DESIGN: A consensus committee of 26 experts was formed. A formal conflict of interest (COI) policy was developed at the onset of the process and enforced throughout. The entire guidelines process was conducted independently of any industrial funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. METHODS: The last SFAR and CNGOF guidelines on the management of women with severe preeclampsia was published in 2009. The literature is now sufficient for an update. The aim of this expert panel guidelines is to evaluate the impact of different aspects of the management of women with severe preeclampsia on maternal and neonatal morbidities separately. The experts studied questions within 7 domains. Each question was formulated according to the PICO (Patients Intervention Comparison Outcome) model and the evidence profiles were produced. An extensive literature review and recommendations were carried out and analyzed according to the GRADE® methodology. RESULTS: The SFAR/CNGOF experts panel provided 25 recommendations: 8 have a high level of evidence (GRADE 1±), 9 have a moderate level of evidence (GRADE 2±), and for 7 recommendations, the GRADE method could not be applied, resulting in expert opinions. No recommendation was provided for 3 questions. After one scoring round, strong agreement was reached between the experts for all the recommendations. CONCLUSIONS: There was strong agreement among experts who made 25 recommendations to improve practices for the management of women with severe preeclampsia.
