[Development of a measuring tool for performance anxiety in obstetrics]. / Développement d'un outil d'évaluation de l'anxiété de performance en obstétrique.

OBJECTIVE: Developing a measuring tool for physician's performance anxiety during obstetrical procedures, as a self-administered questionnaire. METHODS: We used the Delphi method. First, we did a literature review to identify the items to submit for the first round. A panel of experts was asked to rate the relevance of items from one to six. For the first round of Delphi, items were retained if more than 70% of respondents assigned a five or six rating. Items were excluded if more than 70% of respondents assigned a one or two rating. All the other items, plus those suggested by the panel, were submitted to a second round of Delphi. The same item selection conditions were applied to the second round. RESULTS: The overall response rate to the Delphi was 79% (19 respondents). At the end of the first round, 14 items were consensually relevant, no item was consensually irrelevant. For the second round, the 18 items that did not find consensus and seven new items suggested by the experts in the first round were submitted. At the end of the second round, nine items were retained by consensus as relevant. CONCLUSION: This study defined by consensus 23 items for a self-questionnaire to measure specific performance anxiety in obstetrics divided into five dimensions: perceived stress, assessment of the risk of complications, medico-legal risk, impact of the healthcare team and peers, self-confidence and decision-making confidence. We intend to validate this tool in real population.

The role of pediatric oncologist in prenatal diagnosis: A 10-year retrospective study at Assistance Publique Hôpitaux de Marseille (AP-HM).

Solid tumors or predisposition syndromes are increasingly suspected before birth. However optimal management and outcomes remain unclear. We have performed a ten-year retrospective study of oncologic indications of prenatal diagnosis in public hospitals in Marseille. Data were obtained from prenatal diagnosis center and hospital imaging databases and pediatric oncology department files. Fifty-one cases were identified, 40 with mass: adrenal 17, sacrococcygeal 9, cardiac 7, abdominal 4, ovarian 1, cervical 2; 8 with developmental abnormalities (omphalocele 4, macroglossia 4), 3 WITH familial predisposition syndromes (familial rhabdoid 2, Li-Fraumeni 1). Median detection time was 30 week. Termination of pregnancy was decided for 9 fetuses (4 cardiac lesions and suspected tuberous sclerosis, 2 sacrococcygeal tumors, 1 Beckwith-Wiedemann Syndrome, 2 SMARCB1 mutations. Preterm birth occurred in 8 cases. Eleven newborns (26,1%) required intensive care (8 for mechanical complications). Of of 17 adrenal mass ES, 4 disappeared before birth and 5 before one year. Seventeen newborns underwent surgery: 13 masses (teratoma 7, myelomeningocele 2, cystic nephroma 1, neuroblastoma 2), 4 omphaloceles, one biopsy. Surgery performed after one year for incomplete regression identified 1 neuroblastoma, 2 bronchogenic cysts and 2 nonmalignant masses. Three newborns received chemotherapy. Except one patient with BWS who died of obstructive apnea, all children are alive disease free with a median follow-up of 60 months [9-131 months]. Twelve have sequelae. Various solid tumors and cancer predisposition syndromes can be detected before birth. A multidisciplinary collaboration is strongly recommended for optimal management before and after birth.

Chorionicity and neurodevelopmental outcomes at 5½ years among twins born preterm: the EPIPAGE2 cohort study.

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.

Does a physiology-based interpretation of cardiotocography allow to dispense with second-line methods? A cross-sectional online survey.

CONTEXT: Second line methods are used to help obstetricians to identify abnormalities that reflect foetal acidosis. Since the use of a new technique of cardiotocography (CTG) interpretation based on the pathophysiology of the foetal period, the use of second-line tests has been questioned. OBJECTIVE: To evaluate the impact of specific training in CTG physiology-based interpretation on professional attitudes towards the use of second-line methods. METHODS: This cross-sectional study included 57 French obstetricians divided into two groups: the trained group (obstetricians who had already participated in a training course in physiology-based interpretation of CTG) and the control group. Ten medical records of patients who had abnormal CTG tracings and underwent foetal blood sampling pH measurement during labour were presented to the participants. They were given three choices: use a second-line method, continue labour without using second-line method, or perform a caesarean section. The main outcome measures was the median number of decisions to use second-line method. RESULTS: Forty participants were included in the trained group and 17 in the control group. The median number of recourses to second-line method was significantly inferior for the trained group (4/10 s-line methods) than for the control group (6/10, p = 0.040). Regarding the 4 records for which a caesarean section was the real outcome, the median number of decisions of continuing labour was significantly superior in the trained group than in the control group (p = 0.032). CONCLUSIONS: Participation in a training course in physiology-based interpretation of CTG could be associated with a less frequent use of second-line method at the cost of more frequently continuing labour with the risk compromising foetal and maternal well-being. Additional studies are required to determine whether this change in attitude is safe for the foetal well-being.

Relevance of Fetal Brain Magnetic Resonance Imaging Compared to Ultrasound for Detecting Cerebral Anomalies in Fetuses with Cleft Lip and/or Palate: A Cohort Study.

INTRODUCTION: Relevance of fetal brain magnetic resonance imaging (MRI) in cases of cleft lip and/or palate (CL/P) is still discussed to date. The aim of our study was to review the contribution of fetal brain MRI for detecting cerebral anomalies in cases of CL/P comparing antenatal data with neonatal outcomes. METHODS: A retrospective multicenter study was conducted from January 2010 to October 2020 in two multidisciplinary prenatal diagnosis centers among women with a fetal ultrasound (US) diagnosis of CL/P. Prenatal imaging and genetic analysis data were collected, as well as postnatal data, including outcomes of children who had an abnormal prenatal MRI. RESULTS: Among the 202 fetuses with a US diagnosis of CL/P, 96 underwent US and fetal brain MRI. 19 brain MRIs were found to be abnormal: 14 (73.7%) involved CL/P associated with other US abnormalities and five (26.3%) involved isolated clefts, of which four were cleft lip and alveolus and secondary palate (CLP). MRI identified severe abnormalities that changed the prognoses of 3 cases of clefts associated with other US abnormalities. In contrast, MRI found only minor abnormalities for the five isolated clefts, with no postnatal disorders found in these children. CONCLUSION: Fetal brain MRI should be proposed in cases of clefts associated with other anomalies or if US examination is limited by local conditions. MRI could also be discussed in cases of isolated CLP but should not be performed in cases of isolated cleft lip.

The introduction of a universal transvaginal cervical length screening program is associated with a reduced preterm birth rate.

BACKGROUND: Midtrimester sonographic short cervix is a good predictor of preterm birth in singleton pregnancies. OBJECTIVE: This study aimed to assess the impact of implementing a universal transvaginal cervical length screening program on preterm birth rate. STUDY DESIGN: This study consisted of 2 parts: a before-and-after multicenter study and a study on the ECHOCOL ("echo"="ultrasound" and "col"="cervix" in French) prospective cohort. We compared the rate of preterm birth before and after the introduction of universal cervical length screening at the time of midtrimester anatomy ultrasound. The multicenter before-and-after regional study included all women with a singleton pregnancy who gave birth after 24 weeks' gestation in the South East of France from January 1, 2012 to April 30, 2018. In parallel, the ECHOCOL cohort study was prospectively conducted from May 2015 to July 2018, including 17 maternity hospitals in the South East region of France. In case of asymptomatic short cervix <25 mm, treatments offered included 200 mg of vaginal progesterone, or cerclage, or a pessary until 34 weeks' gestation. RESULTS: We observed a significant decrease rate of preterm birth between periods A and B after multivariate analysis. (respectively, 5.8% vs 5.6%; adjusted odds ratio, 0.92; 95% confidence interval, 0.89-0.95; P<.0001). In parallel, the percentage of cervical length screening significantly increased from 28.9% in period A to 52.9% in period B (odds ratio, 2.76; 95% confidence interval, 2.71-2.80; P<.0001). Among the 3468 patients of the ECHOCOL prospective cohort, 38 (1.1%) asymptomatic short cervices were detected, and 192 patients gave birth prematurely (11 with an asymptomatic short cervix and 181 without). In the ECHOCOL cohort, a marked but statistically insignificant tendency toward a reduced rate of preterm birth before 37 weeks of gestation was observed (from 5.8% to 5.5%; adjusted odds ratio, 0.72; 95% confidence interval, 0.51-1.03; P=.068). CONCLUSION: This study showed a significantly lower rate of preterm birth after the implementation of a universal cervical length screening and treating policy during the second trimester of pregnancy. The clinical trial was registered under NCT02598323.

Uncertain fetal head engagement: a prospective randomized controlled trial comparing digital exam with angle of progression.

BACKGROUND: Uncertain fetal head engagement represents 4% of obstetrical situations associated with an increased risk of postpartum hemorrhage, notably in cases of cesarean delivery and increased neonatal impairment owing to failed vaginal instrumental delivery. In this obstetrical condition, cesarean delivery is recommended, but vaginal delivery is possible in two-thirds of the cases. During the second stage of labor, the descent of the fetal head can be assessed by sonography, particularly by measuring the angle of progression. OBJECTIVE: To evaluate, after a prolonged second stage of labor, the impact of measuring the angle of progression in addition to a digital examination on cesarean delivery rates when fetal head engagement remains uncertain. STUDY DESIGN: This open multicenter randomized pragmatic trial included women at term with a singleton cephalic fetus in a clinical occiput anterior position after a prolonged 2-hour second stage of labor with uncertain fetal head engagement. After inclusion in the study, an independent investigator performed ultrasound systematically to confirm the occiput anterior position and measured the angle of progression at the climax of Valsalva pushing. This operator did not participate in labor management. In the study group but not in the control group, the angle of progression was communicated to the obstetrician in charge of labor management. Obstetricians were encouraged to attempt vaginal birth if the angle of progression was >120°. The primary outcome was the cesarean delivery rate. Secondary outcomes were operative delivery rate (cesarean delivery and operative vaginal delivery), maternal complications (third and fourth-degree perineal tears, failed vaginal instrumental delivery, postpartum hemorrhage, hysterectomy), and neonatal outcomes (Apgar score <5 at 10 minutes, umbilical arterial pH <7.10, neonatal wounds, neonatal intensive care unit admission). RESULTS: A total of 45 women were included in the study. Occiput anterior position was confirmed in 33 women: 16 in the study group and 17 in the control group. Women's characteristics at baseline were similar between the groups. The median (range) angles of progression were similar: 138.4° (15) and 140.3° (16.9) in the study and control group, respectively. Cesarean delivery rates were 12.5% in the study group and 41.1% in the control group (P=.06). Secondary outcomes were similar between the 2 groups. No failed vaginal instrumental delivery was reported. CONCLUSION: Measurement of the angle of progression in addition to digital examination when fetal head engagement remained uncertain showed promising results in decreasing cesarean delivery rates. A larger multicenter randomized controlled trial is needed to confirm these results.

Selective intrauterine growth restriction of monochorionic diamniotic twin pregnancies: What is the neonatal prognosis?

OBJECTIVE: This study compares the neonatal morbidity and mortality of the smallest twins of monochorionic diamniotic (MCDA) pregnancies complicated with selective intrauterine growth restriction (sIUGR) with newborns from singleton pregnancies with intrauterine growth restriction (IUGR). METHODS: We conducted a retrospective cohort study of patients managed at the prenatal diagnosis center in a single tertiary care hospital between 2012 and 2019. MCDA twin pregnancies complicated with sIUGR (sIUGR group) were compared with singleton pregnancies with IUGR (IUGR group). The primary outcome was the comparison in neonatal morbidity and mortality between the two groups. RESULTS: The analysis included 251 patients: 67 in the sIUGR group and 184 in the IUGR group. The two groups were comparable in gestational age and birth weight (p > 0.05). Multivariate analysis controlling for factors that may influence neonatal status showed no significant difference between the two groups in any of the neonatal morbidity criteria or the composite morbidity-mortality endpoint (adjusted OR = 0.946 [95% CI = 0.317-2.827]; p = 0.921). CONCLUSION: Despite supposedly different pathophysiological mechanisms, neonates from MCDA pregnancies complicated with sIUGR and those from singleton pregnancies with IUGR appear to have identical neonatal morbidity and mortality .

Severe maternal morbidity in preterm cesarean delivery: A systematic review and meta-analysis.

OBJECTIVE: More than half of extremely preterm infants are delivered by cesarean section. Few data are available about severe maternal morbidity (SMM) of these extremely preterm cesarean. The objective was to determine whether gestational age under 26 weeks of gestation (weeks) was associated with an increased risk of SMM compared with gestational age between 26 and 34 weeks in women having a cesarean delivery. MATERIAL AND METHODS: We searched MEDLINE, ISI Web of Science, the Cochrane Database, PROSPERO, and ClinicalTrials.gov on January 31, 2020. The search strategy clustered terms describing SMM and preterm cesarean delivery. No restrictions on language, publication status, and study design were applied. Abstracts were included if there was sufficient information to assess study quality. The authors of all identified studies were contacted to request for aggregated data. Relative risks (RR) were calculated using the inverse variance method. The primary outcome was SMM as defined in each study. We analyzed data on preterm cesarean deliveries between 22 and 34 weeks. The protocol was registered in PROSPERO (registration: CRD42019128644). RESULTS: Six studies involving 45,572 women (3,440 delivering < 26 weeks; 42,132 delivering between 26 and 34 weeks) were included. SMM occurred in 607 women (17.6 %) < 26 weeks and 4,483 women (10.6 %) between 26 and 34 weeks. Gestational age < 26 weeks was associated with an increased risk of SMM (RR, 1.65; 95 % CI [Confidence Interval], 1.52-1.78; I2 = 40 %). Gestational age < 26 weeks remained associated with SMM in the subgroup analyses depending on the type of the study (prospective or retrospective), country of the study (European or non-European), and high quality of the study. A sensitivity analysis showed that gestational age < 25 weeks was also associated with SMM in preterm cesarean delivery (RR, 1.66; 95 % CI, 1.50-1.83; I2 = 3%). CONCLUSIONS: Gestational age < 26 weeks was associated with an increased risk of SMM in women having a preterm cesarean delivery. Obstetricians and neonatologists should be aware of the increased risk of SMM in cesarean.

Prophylactic manual rotation of occiput posterior and transverse positions to decrease operative delivery: the PROPOP randomized clinical trial.

BACKGROUND: Persistent occiput posterior and occiput transverse positions are the most common malpositions of the fetal head during labor and are associated with prolonged second stage of labor, cesarean deliveries, instrumental deliveries, severe perineal tears, postpartum hemorrhage, and chorioamnionitis. Manual rotation is one of several strategies described to deal with these malpositions. OBJECTIVE: This study aimed to determine if the trial of prophylactic manual rotation at the early second stage of labor is associated with a decrease in operative deliveries (instrumental and/or cesarean deliveries). STUDY DESIGN: We conducted a multicenter, open-label, randomized controlled trial in 4 French hospitals. Women with singleton term pregnancy and occiput posterior or occiput transverse position confirmed by ultrasound at the early second stage of labor and with epidural analgesia were eligible. Women were randomly assigned (1:1) to either undergo a trial of prophylactic manual rotation of occiput posterior or occiput transverse position (intervention group) or no trial of prophylactic manual rotation (standard group). The primary outcome was operative delivery (instrumental and/or cesarean deliveries). The secondary outcomes were length of the second stage of labor, maternal complications (postpartum hemorrhage, operative complications during cesarean delivery, episiotomy and perineal tears), and neonatal complications (Apgar score of <5 at 10 minutes, arterial umbilical pH of <7.10, neonatal injuries, neonatal intensive care unit admission). The main analysis was focused on intention-to-treat analysis. RESULTS: From December 2015 to December 2019, a total of 257 women (mean age, 30.4 years; mean gestational age, 40.1 weeks) were randomized: 126 were assigned to the intervention group and 131 were assigned to the standard group. Operative delivery was significantly less frequent in the intervention group compared with the standard group (29.4% [37 of 126] vs 41.2% [54 of 131]; P=.047; differential [intervention-standard] [95% confidence interval] = -11.8 [-15.7 to -7.9]; unadjusted odds ratio [95% confidence interval] = 0.593 [0.353-0.995]). Women in the intervention group were more likely to have a significantly shorter second stage of labor. CONCLUSION: Trial of prophylactic manual rotation of occiput posterior or occiput transverse positions during the early second stage of labor was statistically associated with a reduced risk of operative delivery. This maneuver could be a safe strategy to prevention operative delivery.

Accuracy of prenatal screening for congenital heart disease in population: A retrospective study in Southern France.

Congenital heart diseases (CHDs) are the most common congenital malformations. The objective of our study was to evaluate the prenatal screening accuracy of congenital heart disease (CHD) in Southern France and to evaluate the impact of a prenatal diagnosis on pregnancies outcomes and neonatal outcomes. We performed a bicentric, retrospective observational study in the southern region over 4 years was conducted between 1 January 2014 and 31 December 2017. All foetuses and children under one year of age with CHD monitored in the UTHs (University Teaching Hospitals) in Marseille and Nice were included. CHD cases were divided into 3 groups: group 1, those with no possible options for anatomical repair; group 2, those with anatomical repair possibilities but that may require neonatal cardiologic management; and group 3, those with anatomical repair possibilities that do not require an emergency neonatal procedure. Among the 249070 deliveries during the study period, 677 CHD cases were included in the study. The overall prenatal screening rate was 71.5%. The screening rates were 97.8%, 63.6%, and 65.9% for groups 1, 2 and 3, respectively. Among group 2 CHD cases, 80% of the transpositions of the great arteries, 56% of the aortic coarctations, and 20% of the total anomalous pulmonary venous returns were detected during the prenatal period. A genetic anomaly was found in 16% of CHD cases. The overall mortality rate was 11.3% with a higher death rate in cases of prenatal screening (17.2% versus 2.1%; p < 0.001). However, when focusing only on children who died of CHD, prenatal screening did not create an impact (56.6% versus 100%, p = 0,140). Our data showed that the prenatal screening rate of CHD appears satisfactory in Southern France. Nevertheless, it could be improved for some CHD. This study did not find any benefit in terms of mortality from prenatal screening for CHD.

Lower gestational age is associated with severe maternal morbidity of preterm cesarean delivery.

OBJECTIVE: To evaluate whether gestational age was associated with the severe maternal morbidity (SMM) of preterm cesarean delivery between 22 and 34 weeks of gestation (weeks). MATERIAL AND METHODS: We performed an observational retrospective cohort study in two tertiary university hospitals in 2018. We included all mothers of preterm infants born by caesarean delivery between 22 and 34 weeks, excluding mothers with multiple births greater than two, with pregnancy terminations or stillbirths, and who died unrelated to obstetrical causes. The principal endpoint, SMM, was a composite outcome (classical uterine incision, postpartum hemorrhage defined by blood loss ≥ 500 mL, blood transfusion, any injury to adjacent organs, unplanned procedure/need for reintervention, Intensive Care Unit (ICU) stay longer than 24 h, postpartum fever, and/or death). RESULTS: Among the 252 women, SMM occurred in 89 (35.3 %) cases. After multivariate analysis, gestational age was independently associated with SMM (adjusted Odds Ratio [aOR] 0.87; 95 % Confidence Interval [CI] 0.78-0.97). The other variables statistically associated with SMM were type of pregnancy with a negative association with twin pregnancy (aOR, 0.44; 95 % CI, 0.20-0.93) and a positive association with general anesthesia (aOR, 2.52; 95 % CI, 1.25-5.13). A sensitivity analysis was performed and found an association, at the limit of significance, between gestational age < 28 weeks and SMM (aOR, 1.80; 95 % CI, 0.99-3.27, p = 0.05). CONCLUSION: Lower gestational age was associated with the risk of SMM for preterm caesarean delivery between 22 and 34 weeks. Obstetricians should integrate this knowledge into their shared decision-making processes with parents.

Is failure of fetal head engagement during previous delivery a contraindication for trial of labor: A French retrospective study.

OBJECTIVE: To study whether history of cesarean delivery for arrest of descent (failure of fetal head engagement or unsuccessful instrumental delivery), is a factor of unsuccessful vaginal birth after cesarean delivery. METHODS: Multicenter prospective study of patients undergoing TOL after previous caesarean delivery between May 2012 and May 2013 in 6 maternities. Univariate statistical analysis was performed depending of previous cesarean delivery indication. Multivariate analysis was used to determine independent association between these factors and TOLAC success. RESULTS: Four hundred and eighty women with previous cesarean delivery were included and separated into two groups: the study group was composed of patients with history of CD for arrest of descent (failure of fetal head engagement or unsuccessful instrumental delivery) (n=31); control group included all other indications for CD (n=449). Overall, of the 480 women included in the study, 71.2 % underwent a TOL for a subsequent delivery (n=342): 68 % in the study group (n=21) vs 71.5 % in the control group (n=321). Vaginal birth after cesarean (VBAC) was obtained in 66.6 % vs 61% in the study and control group respectively (p=0.656). Univariate analysis of factors that may influence the success rate of (VBAC) did not show any difference between the two groups. Multivariate analysis showed that VBAC was only significantly associated with history of vaginal delivery subsequent to prior CD for arrest of descent. CONCLUSION: This study reassures us in our clinical practice allowing TOL in cases of history of CD for fetal head engagement failure or instrumental delivery failure in the second stage of labor.

Association between gestational age and severe maternal morbidity and mortality of preterm cesarean delivery: a population-based cohort study.

BACKGROUND: Cesarean delivery rates at extreme prematurity have regularly increased over the past years, and few previous studies have investigated severe maternal morbidity associated with extreme preterm cesarean delivery. OBJECTIVE: The aim of this study was to evaluate whether gestational age <26 weeks of gestation (weeks) was associated with severe maternal morbidity and mortality (SMMM) of preterm cesarean deliveries in comparison with cesarean deliveries between 26 and 34 weeks. MATERIALS AND METHODS: The Etude Epidémiologique sur les petits âges gestationnels (EPIPAGE) 2 is a national prospective population-based cohort study of preterm births in 2011. We included mothers with cesarean deliveries between 22 and 34 weeks, excluding those who had a cesarean delivery for the second twin only and those with pregnancy terminations. SMMM was analyzed as a composite endpoint defined as the occurrence of at least 1 of the following complications: severe postpartum hemorrhage defined by the use of a blood transfusion, intensive care unit admission, or death. To assess the association of gestational age <26 weeks and SMMM, we used multivariate logistic regression and a propensity score-matching approach. RESULTS: Among 2525 women having preterm cesarean deliveries, 116 before 26 weeks and 2409 between 26 and 34 weeks, 407 (14.4%) presented with SMMM. The SMMM occurred in 31 mothers (26.7%) who were at gestational age <26 weeks vs 376 (14.2%) between 26 and 34 weeks (P < .001). Cluster multivariate logistic regression showed significant association of gestational age <26 weeks and SMMM (adjusted odds ratio [aOR], 2.50; 95% confidence interval [CI], 1.42-4.40) and propensity score-matching analysis was consistent with these results (aOR, 2.27; 95% CI, 1.31-3.93). CONCLUSION: Obstetricians should know about the higher SMMM associated with cesarean deliveries before 26 weeks, integrate this knowledge into decisions regarding cesarean delivery, and be prepared to manage the associated complications.

Development of a nomogram for individual preterm birth risk evaluation.

OBJECTIVE: This study aimed to develop a new tool for personalised preterm birth risk evaluation in high-risk population. STUDY DESIGN: 813 high-risk asymptomatic pregnant women included in a French multicentric prospective study were analysed. Clinical and paraclinical variables, including screening for bacterial vaginosis with molecular biology, cervical length, have been used to create the nomogram, based on the logistic regression model. The validity was checked by bootstrap. A downloadable calculator was build. RESULTS: Nine risk factors were included in this model: history of late miscarriage and/or preterm delivery, active smoking, ultrasound cervical length, term of pregnancy at screening, bacterial vaginosis, premature rupture of membranes, daily travel more than 30min. Discrimination and calibration of the nomogram revealed good predictive abilities. The area under the receiver operating characteristic curve was 0.77 (95% CI; 0.72-0.81). The mean absolute error was 0.018, which showed proper calibration. The optimal risk threshold was 23.2% with a sensitivity of 74%, a specificity of 72.7% and a predictive negative value of 90.6%. CONCLUSION: The nomogram can help to better define individual preterm birth risk in high-risk pregnancies.

Preterm premature rupture of membranes at 22-25 weeks' gestation: perinatal and 2-year outcomes within a national population-based study (EPIPAGE-2).

BACKGROUND: Most clinical guidelines state that with early preterm premature rupture of membranes, obstetric and pediatric teams must share a realistic and individualized appraisal of neonatal outcomes with parents and consider their wishes for all decisions. However, we currently lack reliable and relevant data, according to gestational age at rupture of membranes, to adequately counsel parents during pregnancy and to reflect on our policies of care at these extreme gestational ages. OBJECTIVE: We sought to describe both perinatal and 2-year outcomes of preterm infants born after preterm premature rupture of membranes at 22-25 weeks' gestation. STUDY DESIGN: EPIPAGE-2 is a French national prospective population-based cohort of preterm infants born in 546 maternity units in 2011. Inclusion criteria in this analysis were women diagnosed with preterm premature rupture of membranes at 22-25 weeks' gestation and singleton or twin gestations with fetus(es) alive at rupture of membranes. Latency duration, antenatal management, and outcomes (survival at discharge, survival at discharge without severe morbidity, and survival at 2 years' corrected age without cerebral palsy) were described and compared by gestational age at preterm premature rupture of membranes. RESULTS: Among the 1435 women with a diagnosis of preterm premature rupture of membranes, 379 were at 22-25 weeks' gestation, with 427 fetuses (331 singletons and 96 twins). Median gestational age at preterm premature rupture of membranes and at birth were 24 (interquartile range 23-25) and 25 (24-27) weeks, respectively. For each gestational age at preterm premature rupture of membranes, nearly half of the fetuses were born within the week after the rupture of membranes. Among the 427 fetuses, 51.7% were survivors at discharge (14.1%, 39.5%, 66.8%, and 75.8% with preterm premature rupture of membranes at 22, 23, 24, and 25 weeks, respectively), 38.8% were survivors at discharge without severe morbidity, and 46.4% were survivors at 2 years without cerebral palsy, with wide variations by gestational age at preterm premature rupture of membranes. Survival at 2 years without cerebral palsy was low with preterm premature rupture of membranes at 22 and 23 weeks but reached approximately 60% and 70% with preterm premature rupture of membranes at 24 and 25 weeks. CONCLUSION: Preterm premature rupture of membranes at 22-25 weeks is associated with high incidence of mortality and morbidity, with wide variations by gestational age at preterm premature rupture of membranes. However, a nonnegligible proportion of children survive without severe morbidity both at discharge and at 2 years' corrected age.

Prenatal therapy with pyrimethamine + sulfadiazine vs spiramycin to reduce placental transmission of toxoplasmosis: a multicenter, randomized trial.

BACKGROUND: The efficacy of prophylaxis to prevent prenatal toxoplasmosis transmission is controversial, without any previous randomized clinical trial. In France, spiramycin is usually prescribed for maternal seroconversions. A more potent pyrimethamine + sulfadiazine regimen is used to treat congenital toxoplasmosis and is offered in some countries as prophylaxis. OBJECTIVE: We sought to compare the efficacy and tolerance of pyrimethamine + sulfadiazine vs spiramycin to reduce placental transmission. STUDY DESIGN: This was a randomized, open-label trial in 36 French centers, comparing pyrimethamine (50 mg qd) + sulfadiazine (1 g tid) with folinic acid vs spiramycin (1 g tid) following toxoplasmosis seroconversion. RESULTS: In all, 143 women were randomized from November 2010 through January 2014. An amniocentesis was later performed in 131 cases, with a positive Toxoplasma gondii polymerase chain reaction in 7/67 (10.4%) in the pyrimethamine + sulfadiazine group vs 13/64 (20.3%) in the spiramycin group. Cerebral ultrasound anomalies appeared in 0/73 fetuses in the pyrimethamine + sulfadiazine group, vs 6/70 in the spiramycin group (P = .01). Two of these pregnancies were terminated. Transmission rates, excluding 18 children with undefined status, were 12/65 in the pyrimethamine + sulfadiazine group (18.5%), vs 18/60 in the spiramycin group (30%, P = .147), equivalent to an odds ratio of 0.53 (95% confidence interval, 0.23-1.22) and which after adjustment tended to be stronger (P = .03 for interaction) when treatment started within 3 weeks of seroconversion (95% confidence interval, 0.00-1.63). Two women had severe rashes, both with pyrimethamine + sulfadiazine. CONCLUSION: There was a trend toward lower transmission with pyrimethamine + sulfadiazine, but it did not reach statistical significance, possibly for lack of statistical power because enrollment was discontinued. There were also no fetal cerebral toxoplasmosis lesions in the pyrimethamine + sulfadiazine group. These promising results encourage further research on chemoprophylaxis to prevent congenital toxoplasmosis.
