RESUMEN
INTRODUCTION: The use of different growth charts can lead to confusion in discussions between professionals. There are obstetric charts (of fetal growth) and neonatal charts (of measurements at birth and of postnatal growth). These charts can be descriptive (derived from an unselected population) or prescriptive (derived from of a population at low risk and with optimal conditions for growth). OBJECTIVES: (1) To describe available charts for infants at birth and in the neonatal period and compare them, and (2) to recommend one or more charts for use in neonatology in France. METHODS: Bibliographic research was conducted on MEDLINE and completed by the guidelines of professional societies. RESULTS: Antenatal information about fetal growth restriction or fetuses identified as small-for-gestational-age using Intrauterine charts must be integrated into the identification of newborns at risk, but the use of Intrauterine charts to evaluate birthweight is not recommended to allow consistency with postnatal charts used in neonatal practice. Z-score variations using the updated Fenton postnatal charts are the most appropriate for the assessment of birthweight and postnatal growth for infants born preterm. These charts are sex-specific, include the three measurements (length, weight, and head circumference) and enable longitudinal follow-up of growth up to 50 weeks of corrected age and are linked to the World Health Organization charts at term. The French Audipog charts, although are individualized, accessible online and can be used in maternity units to evaluate birthweight for term infants, but do not allow the follow-up of postnatal growth, while Fenton charts may be used to evaluate birthweight and postnatal growth in the first month for hospitalized term infants. CONCLUSION: The updated Fenton charts are the neonatal charts that best suit the objectives of pediatricians in France for monitoring the growth of preterm newborns. The use of the Audipog charts at term remains an alternative in maternity wards, while Fenton charts can be used for hospitalized term newborns.

To evaluate the predictive value of the sFlt-1/PlGF ratio for the prediction of preeclampsia in women with preexisting diabetes mellitus. This is a monocentric retrospective observational study conducted between January 2018 and December 2020. All singleton pregnancies with preexisting diabetes mellitus, who had a dosage of the sFlt-1/PlGF ratio between 30 and 34 + 6 weeks of gestation were included. The principal outcome was preeclampsia. The secondary outcomes were preterm preeclampsia, gestational hypertension, placental abruption, intrauterine fetal death, IUGR, small for gestational age and a composite outcome named "hypertensive disorder of pregnancy" including gestational hypertension, preeclampsia and HELLP syndrome (hemolysis, elevated liver enzymes and low platelet count). Of 63 patients, 22% presented preeclampsia. The area under the curve of sFlt-1/PlGF ratio was 0.90 (95% CI: 0.79-0.96) for the prediction of preeclampsia. The receiver operator characteristic analysis suggested that the optimal sFlt-1/PlGF cutoff to predict preeclampsia was 29, with a sensitivity of 86% (95% CI: 60.1-96.0) and a specificity of 92% (95% CI: 80.8-96.8). A cut-off of 38 provided a sensitivity of 71% (95% CI: 45.4-88.3), a specificity of 92% (95% CI: 80.8-96.8). Further analysis using multivariable methods revealed nephropathy was significantly associated with PE (p = 0.014). The use of the sFlt-1/PlGF ratio during the third trimester of pregnancy seems to be of interest as a prognostic tool to improve multidisciplinary management of patients with preexisting diabetes mellitus.

Substandard or disrespectful care during labour should be of serious concern for healthcare professionals, as it can affect one of the most important events in a woman's life. Substandard care refers to the use of interventions that are not considered best-practice, to the inadequate execution of interventions, to situations where best-practice interventions are withheld from patients, or there is lack of adequate informed consent. Disrespectful care refers to forms of verbal and non-verbal communication that affect patients' dignity, individuality, privacy, intimacy, or personal beliefs. There are many possible underlying causes for substandard and disrespectful care in labour, including difficulties in modifying behaviours, judgmental or paternalistic attitudes, personal interests and individualism, and a human tendency to make less arduous, less difficult, or less stressful clinical decisions. The term "obstetric violence" is used in some parts of the world to describe various forms of substandard and disrespectful care in labour, but suggests that it is mainly carried out by obstetricians and is a serious form of aggression, carried out with the intent to cause harm. We believe that this term should not be used, as it does not help to identify the underlying problem, its causes, or its correction. In addition, it is generally seen by obstetricians and other healthcare professionals as an unjust and offensive term, generating a defensive and less collaborative mindset. We reach out to all individuals and institutions sharing the common goal of improving women's experience during labour, to work together to address the underlying causes of substandard and disrespectful care, and to develop common strategies to deal with this problem, based on mutual comprehension, trust and respect.

BACKGROUND: Induction of labour (IOL) is common practice and different methods carry different effectiveness and safety profiles. OBJECTIVES: To compare the effectiveness, and maternal and perinatal safety outcomes of IOL with vaginal misoprostol versus vaginal dinoprostone using individual participant data from randomised clinical trials. SEARCH STRATEGY: The following databases were searched from inception to March 2023: CINAHL Plus, ClinicalTrials.gov, Cochrane Pregnancy and Childbirth Group Trial Register, Ovid Embase, Ovid Emcare, Ovid MEDLINE, Scopus and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). SELECTION CRITERIA: Randomised controlled trials (RCTs), with viable singleton gestation, no language restrictions, and all published and unpublished data. DATA COLLECTION AND ANALYSIS: An individual participant data meta-analysis was carried out. MAIN RESULTS: Ten of 52 eligible trials provided individual participant data, of which two were excluded after checking data integrity. The remaining eight trials compared low-dose vaginal misoprostol versus dinoprostone, including 4180 women undergoing IOL, which represents 32.8% of all participants in the published RCTs. Of these, 2077 were assigned to low-dose vaginal misoprostol and 2103 were assigned to vaginal dinoprostone. Compared with vaginal dinoprostone, low-dose vaginal misoprostol had a comparable rate of vaginal birth. Composite adverse perinatal outcomes did not differ between the groups. Compared with vaginal dinoprostone, composite adverse maternal outcomes were significantly lower with low-dose vaginal misoprostol (aOR 0.80, 95% CI 0.65-0.98, P = 0.03, I2 = 0%). CONCLUSIONS: Low-dose vaginal misoprostol and vaginal dinoprostone for IOL are comparable in terms of effectiveness and perinatal safety. However, low-dose vaginal misoprostol is likely to lead to a lower rate of composite adverse maternal outcomes than vaginal dinoprostone.

OBJECTIVE: To assess which fetal growth charts best describe intrauterine growth in France defined as the ability to classify 10% of fetuses below the 10th percentile (small for gestational age [SGA]) and above the 90th percentile (large for gestational age [LGA]) in the second and third trimesters. METHODS: We analyzed five studies on fetal ultrasound measurements using three French data sources. Two studies used second and third trimester ultrasound data from a nationwide birth cohort in 2011 (the ELFE study, N = 13 197 and N = 7747); one study used third trimester ultrasound data from on a nationwide cross-sectional study (the 2016 French National Perinatal Survey, N = 9940); and the last two studies were from the "Flash study" 2014 which prospectively collected ultrasound data from routine visits in the second and third trimesters (N = 4858 and N = 3522). For each study, we reported the percentage of measurements below the 10th percentile or above the 90th percentile, using French, Hadlock's, WHO and Intergrowth (IG) charts. RESULTS: WHO classified 4.7% and 16.3% of fetuses as having an estimated fetal weight (EFW) <10th and >90th percentiles in the second trimester compared to 3.3% and 34.7% with IG. The percentage of fetuses in the third trimester with an EFW <10th and >90th percentiles, ranged from 9.1% to 9.4% and from 8.0% to 11.1%, respectively, for WHO, and from 3.9% to 4.1% and from 17.3% to 21.6%, respectively, for IG. The WHO and IG charts for head circumference were very similar and performed well. Compared to the WHO charts, the French and Hadlock's charts deviated more frequently from the target percentiles values for EFW and biometric measures. CONCLUSION: It is recommended to use the WHO charts for the assessment of EFW and ultrasound biometric measurements in France (strong recommendation; low quality of evidence).

In high-resource countries, adverse perinatal outcomes are currently rare in term, non-malformed fetuses, undergoing labor, but they remain a leading cause of medico-legal dispute. Precise terminology is important to describe situations related to inadequate fetal oxygenation in labor, to ensure appropriate communication between healthcare professionals and adequate transmission of information to parents. This position statement provides consensus definitions from European perinatologists and midwives regarding the most appropriate terminology to describe situations related to inadequate fetal oxygenation in labor: suspected fetal hypoxia, severe newborn acidemia, newborn metabolic acidosis, and hypoxic-ischemic encephalopathy. It also identifies terms that are imprecise or nonspecific to this situation, and should therefore be avoided by healthcare professionals: fetal well-being, fetal stress, fetal distress, non-reassuring fetal state, and birth asphyxia.

OBJECTIVE: To describe maternal and fetal outcomes of pregnancies after 42 years and to compare maternal and fetal morbidities according to the conception mode; comparing pregnancies obtained spontaneously and those resulting from assisted reproductive technology (ART). METHODS: This retrospective cohort study was conducted in a level 3 maternity hospital. This study covered all women, aged 42 years or older, who gave birth between January 1, 2014 and December 31, 2019. Univariate and multivariate analyses with logistic regression models were used to compare maternal and perinatal outcomes depending on conception mode: spontaneous or using ART. RESULTS: A sample of 532 women, including 335 spontaneous pregnancies (63%) and 147 pregnancies after ART (27.6%) were studied. Conception mode was missing for 50 (9.4%). We found increased rates not only of maternal complications such as maternal overweight and obesity, pre-eclampsia, and gestational diabetes, but also of interventions such as hospitalization during pregnancy, cesarean section, postpartum hemorrhage, and perinatal outcome like preterm birth. There were also more maternal and perinatal negative outcomes among the ART group. After multivariate analysis, pre-eclampsia was predominant in the ART group (odds ratio 0.25, 95% confidence interval 0.07-0.85, P = 0.02). CONCLUSION: While maternal and fetal risks increase for late pregnancies, there also appears to be a difference depending on the conception mode, with pregnancies resulting from ART having more pregnancy-related complications than those obtained spontaneously.

In cervical cancer screening programs, the detection of high-risk human papillomavirus (HR-HPV) is now widely implemented on physician-collected samples and has expanded to include self-collected samples. The use of a cellularity control (CC) is needed to reduce false-negative HPV results. An external mRNA CC for the HPV APTIMA® assay was assessed for its analytical performance and the results were compared with both cervix cytobrush samples taken by physicians and self-collected vaginal samples from 148 women. The performance of the CC was adjusted to control for the presence of cellular mRNA in the ThinPrep® and Multitest® transport media. This CC is user-friendly but implies to perform two independent assays on PANTHER® automate. Self-collected vaginal sampling gives a lower median CC results (13.2 vs. 16.9 min) but a higher risk of negative CC results (3.3 vs. 0%). The usefulness of the CC for the HR-HPV assay may be optimized by the definition of a threshold for a minimum cell number to be tested to increase confidence in HPV-negative results. The systematic use of an RNA CC increases confidence for HPV RNA assays on self-collected vaginal samples.

Few reports of laser coagulation for foetal bronchopulmonary sequestration (BPS), a rare congenital malformation characterised by the absence of tracheobronchial connection and the presence of a systemic feeding artery, have been published. Additionally, very few of them focus also on the postnatal management, with results limited and controversial. Postnatal treatment of residual malformation remains debated, hence the need to share our experience of a combined pre- and postnatal approach to complicated extra-lobar BPS. We report the case of a female foetus with the diagnosis of a pulmonary lesion. Due to mediastinal shift, unilateral compressive hydrothorax, ascites, and hydrops, a foetal treatment with ultrasound-guided laser coagulation of the anomalous vessel was performed. At birth, due to the persistence of the malformation, an elective delayed thoracoscopical surgery was performed. Prenatal laser ablation for complicated BPS is a life-saving procedure not always resulting in lesion disappearance. Thoracoscopical surgical exploration in case of persistent lesions at birth offers the possibility of a minimally invasive sequestrectomy feasible and safe.
RESUMEN
OBJECTIVE: Preterm birth, defined as birth before 37 weeks of gestation, is a leading cause of perinatal and infant mortality throughout the world. Preterm birth is also associated with long-term neurological disabilities and other significant health issues in children. A short cervix in the second trimester has been noted to be one of the strongest predictors of subsequent spontaneous preterm birth in both singleton and multiple pregnancies. Some studies have shown that cervical support in the form of an Arabin pessary lowers the risk of preterm birth in women with a singleton gestation and short cervical length; however, other studies have conflicting results. Our objective was to form an international collaborative of planned or ongoing randomized trials of pessary in singleton and twin gestations with a short cervix. STUDY DESIGN: In November 2014, an international group of investigators, who had initiated or were planning randomized trials of pessary for pregnant people with a short cervix and singleton or twin gestation to prevent preterm birth, formed a collaboration to plan a prospective individual patient data (IPD) meta-analysis of randomized trials (PROspective Meta-analysis of Pessary Trials [PROMPT]). The PROMPT investigators agreed on meta-analysis IPD hypotheses for singletons and twins, eligibility criteria, and a set of core baseline and outcome measures. The primary outcome is a composite of fetal death or preterm delivery before 32 weeks' gestation. Secondary outcomes include maternal and neonatal morbidities. The PROMPT protocol may be viewed as a written agreement among the study investigators who make up the PROMPT consortium (PROSPERO ID# CRD42018067740). RESULTS: Results will be published in phases as the individual participating studies are concluded and published. Results of the first phase of singleton and twin pessary trials are expected to be available in late 2022. Updates are planned as participating trials are completed and published. KEY POINTS: · Short cervical length predicts preterm birth.. · Results of prior cervical pessary trials are mixed.. · Meta-analysis of pessary trials protocol..
RESUMEN
BACKGROUND: Recent observational studies reported a high rate of suboptimal use of antenatal corticosteroids (too anticipated or retrospectively not indicated) for women at risk of preterm delivery despite a recommended use within 7 days before delivery. OBJECTIVE: This study aimed to elaborate a nomogram aiming at optimizing the timing of administration of antenatal corticosteroids in case of threatened preterm labor, asymptomatic short cervix, or uterine contractions. STUDY DESIGN: This was an observational retrospective study conducted in a tertiary hospital. All women between 24 and 34 weeks of gestation who received corticosteroids during hospitalization for threatened preterm delivery, asymptomatic short cervix, or uterine contractions requiring tocolysis between 2015 and 2019 were included. Clinical, biological, and sonographic data of women were used to construct logistic regression models for predicting delivery within 7 days. The model was validated on an independent series of women hospitalized in 2020. RESULTS: Among the 1343 women included in this study, the risk factors independently associated with a delivery within 7 days in multivariate analysis were vaginal bleeding (odds ratio, 14.47; 95% confidence interval, 7.81-26.81; P<.001); need for a second-line tocolysis, such as atosiban (odds ratio, 5.66; 95% confidence interval, 3.39-9.45; P<.001); C-reactive protein level (per 1 mg/L increase; odds ratio, 1.03; 95% confidence interval, 1.02-1.04; P<.001); cervical length (per 1 mm increase; odds ratio, 0.84; 95% confidence interval, 0.82-0.87; P<.001); uterine scar (odds ratio, 2.98; 95% confidence interval, 1.33-6.65; P=.008), and gestational age at admission (per week of amenorrhea increase; odds ratio, 1.10; 95% confidence interval, 1.00-1.20; P=.041). Based on these results, a nomogram was developed that, in retrospect, would have allowed physicians to avoid or delay antenatal corticosteroids in 57% of cases in our population. The discrimination of the predictive model was good when applied to the validation set of 232 women hospitalized in 2020. It would have enabled physicians to avoid or delay antenatal corticosteroids in 52% of cases. CONCLUSION: This study developed a simple use, accurate prognostic score to identify women at risk of delivery within 7 days in cases of threatened preterm delivery, asymptomatic short cervix, or uterine contractions and thereby optimized the use of antenatal corticosteroids.

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.

INTRODUCTION: Periodontal diseases (gingivitis and periodontitis) are chronic non-communicable inflammatory diseases. The risk of developing gingivitis and periodontitis increases during pregnancy. Also, periodontitis increases the risk of developing adverse pregnancy outcomes such as preterm birth and preeclampsia. Early diagnosis of adverse pregnancy outcomes is essential and periodontitis could be an early sign to take into consideration. MATERIAL AND METHODS: We conducted a longitudinal observational study (PERISCOPE study: CNIL, no. 1 967 084 v 0; CER, no. 01-0416) on 121 pregnant women in the first trimester to determine their oral and periodontal health status. We explored the relations between oral and periodontal health status and sociodemographic and behavior characteristics, as well as their course and outcome of pregnancy. RESULTS: A total of 47.1% of the women had periodontitis, of which only 66.7% presented clinical manifestations associated with the disease such as gingival bleeding. These women had a poorer oral and periodontal health, and a higher body mass index, and more of them developed gestational diabetes during the course of pregnancy. The remaining 33.3% showed only discreet and isolated inflammatory signs and, unless thoroughly examined, would have gone undiagnosed for periodontitis. Interestingly these women were more often primiparous, still active professionally and had had a recent oral examination. CONCLUSIONS: The PERISCOPE study is one of the few studies that reports the oral and periodontal health status of pregnant women in the first trimester. Furthermore, the results highlight the need for early oral and periodontal assessment and treatment, even in the absence of exterior clinical signs, in order to prevent periodontal disease aggravation and also, by reducing low grade systemic inflammation, possibly adverse pregnancy outcomes.

OBJECTIVE: To assess whether standardised longitudinal reporting of growth monitoring information improves antenatal detection of infants who are small for gestational age (SGA), compared with usual care. DESIGN: Cluster-randomised controlled trial. SETTING: Sixteen French level-3 units in 2018-2019. POPULATION: Singleton pregnancies. METHODS: The intervention consisted of the serial plotting of symphysis-fundal height (SFH) and estimated fetal weight (EFW) measurements on customised growth charts using a software program, compared with standard antenatal care. We estimated relative risks (RR) adjusted for known risk factors for fetal growth restriction (FGR). MAIN OUTCOME MEASURES: The primary outcome was antenatal detection of FGR among SGA births (with birthweights below the tenth centile of French customised curves), defined as the mention of suspected FGR in medical records and either referral ultrasounds for growth monitoring or indicated delivery for FGR. Secondary outcomes were false-positive rates, mode of delivery, perinatal morbidity and mortality, and number of antenatal visits and ultrasounds. RESULTS: In total, seven intervention clusters (n = 4349) and eight control clusters (n = 4943) were analysed, after the exclusion of one intervention centre for a major deviation in protocol. SGA births represented 613 (14.1%) and 626 (12.7%) of all births, respectively. The rates of antenatal detection of FGR among SGA births were 40.0% in the intervention arm versus 37.1% in the control arm (crude RR 1.08, 95% CI 0.87-1.34; adj RR 1.09, 95% CI 0.88-1.35). No benefits of the intervention were detected in the analyses of secondary outcomes. CONCLUSIONS: Serial plotting of SFH and EFW measurements on customised growth charts did not improve the antenatal detection of FGR among SGA births.

BACKGROUND: About 1.3 million pregnant women lived with HIV and were eligible to receive antiretroviral therapy (ART) worldwide in 2021. The World Health Organization recommends protease inhibitors (PI)-based regimen as second or third-line during pregnancy. With remaining pregnant women exposed to PIs, there is still an interest to assess whether this treatment affects perinatal outcomes. Adverse perinatal outcomes after prenatal exposure to PI-based ART remain conflicting: some studies report an increased risk of preterm birth (PTB) and low-birth-weight (LBW), while others do not find these results. We assessed adverse perinatal outcomes associated with prenatal exposure to PI-based compared with non-nucleoside reverse transcriptase (NNRTI)-based ART. METHODS: We performed a systematic review searching PubMed, Reprotox, Clinical Trial Registry (clinicaltrials.gov) and abstracts of HIV conferences between 01/01/2002 and 29/10/2021. We used Oxford and Newcastle-Ottawa scales to assess the methodological quality. Studied perinatal outcomes were spontaneous abortion, stillbirth, congenital abnormalities, PTB (< 37 weeks of gestation), very preterm birth (VPTB, < 32 weeks of gestation), LBW (< 2500 grs), very low-birth-weight (VLBW, < 1500 g), small for gestational age (SGA) and very small for gestational age (VSGA). The association between prenatal exposure to PI-based compared to NNRTI-based ART was measured for each adverse perinatal outcome using random-effect meta-analysis to estimate pooled relative risks (RR) and their corresponding 95% confidence intervals (CI). Pre-specified analyses were stratified according to country income and study quality assessment, and summarized when homogeneous. RESULTS: Out of the 49,171 citations identified, our systematic review included 32 published studies, assessing 45,427 pregnant women. There was no significant association between prenatal exposure to PIs compared to NNRTIs for VPTB, LBW, SGA, stillbirth, and congenital abnormalities. However, it was inconclusive for PTB, and PI-based ART is significantly associated with an increased risk of VSGA (sRR 1.41 [1.08-1.84]; I2 = 0%) compared to NNRTIs. CONCLUSIONS: We did not report any significant association between prenatal exposure to PIs vs NNRTIs-based regimens for most of the adverse perinatal outcomes, except for VSGA significantly increased (+ 41%). The evaluation of antiretroviral exposure on pregnancy outcomes remains crucial to fully assess the benefice-risk balance, when prescribing ART in women of reproductive potential with HIV. PROSPERO NUMBER: CRD42022306896.

OBJECTIVE: To assess the association between marked variability in fetal heart rate (FHR) and neonatal acidosis. DESIGN: Bicentric prospective cohort study. SETTING: From January 2019 to December 2019, in two French tertiary care maternity units. POPULATION: Women in labour at ≥37 weeks of gestation, with continuous FHR monitoring until delivery and with the availability of umbilical arterial pH. Women with intrauterine fetal death or medical termination, multiple pregnancies, non-cephalic presentation or planned caesarean delivery were excluded. METHODS: The exposure was marked variability in FHR in the 60 minutes before delivery, defined as a variability greater than 25 beats per minute, with a minimum duration of 1 minute. To assess the association between marked variability and neonatal acidosis, we used multivariable modified Poisson regression modelling. We then conducted subgroup analyses according to the US National Institute of Child Health and Human Development (NICHD) category of the associated fetal heart rate. MAIN OUTCOME MEASURES: Neonatal acidosis, defined as an umbilical artery pH of ≤7.10. RESULTS: Among the 4394 women included, 177 (4%) had marked variability in fetal heart rate in the 60 minutes before delivery. Acidosis occurred in 6.0% (265/4394) of the neonates. In the multivariable analysis, marked variability was significantly associated with neonatal acidosis (aRR 2.30, 95% CI 1.53-3.44). In subgroup analyses, the association between marked variability and neonatal acidosis remained significant in NICHD category-I and category-II groups. CONCLUSIONS: Marked variability was associated with a twofold increased risk of neonatal acidosis.

INTRODUCTION: This trial evaluates whether daily low-dose aspirin initiated before 16 weeks of gestation can reduce preeclampsia and fetal growth restriction in nulliparous women identified by first-trimester uterine artery Dopplers as at high risk of preeclampsia. METHODS: This randomized, blinded, placebo-controlled, parallel-group trial took place in 17 French obstetric departments providing antenatal care. Pregnant nulliparous women aged ≥ 18 years with a singleton pregnancy at a gestational age < 16 weeks of gestation with a lowest pulsatility index ≥ 1.7 or a bilateral protodiastolic notching for both uterine arteries on an ultrasound performed between 11+0 and 13+6 weeks by a certified sonographer were randomized at a 1:1 ratio to 160 mg of low-dose aspirin or to placebo to be taken daily from inclusion to their 34th week of gestation. The main outcome was preeclampsia or a birthweight ≤ 5th percentile. Other outcomes included preeclampsia, severe preeclampsia, preterm preeclampsia, preterm delivery before 34 weeks, mode of delivery, type of anesthesia, birthweight ≤ 5th percentile and perinatal death. RESULTS: The trial was interrupted due to recruiting difficulties. Between June 2012 and June 2016, 1104 women were randomized, two withdrew consent, and two had terminations of pregnancies. Preeclampsia or a birthweight ≤ 5th percentile occurred in 88 (16.0%) women in the low-dose aspirin group and in 79 (14.4%) in the placebo group (proportion difference 1.6 [-2.6; 5.9] p = 0.45). The two groups did not differ significantly for the secondary outcomes. CONCLUSION: Low-dose aspirin was not associated with a lower rate of either preeclampsia or birthweight ≤ 5th percentile in women identified by their first-trimester uterine artery Doppler as at high risk of preeclampsia. TRIAL REGISTRATION: (NCT0172946).

OBJECTIVE: To evaluate the risk of spontaneous preterm birth on subsequent pregnancies after second stage cesarean section. METHODS: This is a retrospective cohort study. Women were included if they had their two consecutive births in Toulouse University Hospital in the study period. The first birth was a singleton livebirth at term (≥37 weeks of gestation), divided in three categories according to the mode of delivery: vaginal delivery (group A), cesarean section before the second stage of labor (group B), cesarean section during the second stage of labor (group C). The subsequent pregnancy was the first subsequent pregnancy, conducted after 16 weeks of gestation. The primary outcome was spontaneous preterm birth in the subsequent pregnancy, defined as delivery before 37 weeks of gestation. Secondary endpoints included preterm rupture of membranes in the subsequent pregnancy. RESULTS: Between 2003 and 2018, 7776 women (84.7%) in group A, 1263 (13.8%) in group B and 143 (1.5%) in group C were included. The adjusted odds ratio of spontaneous preterm birth before 37 weeks of gestation after second stage cesarean section was 2.4 (group C vs group A + B, 95% confidence interval: 1.2-4.8), P = 0.01). The rate of preterm rupture of membranes was also significantly higher in group C (6% vs 2% in group A, P = 0.009, 6% vs 3% in group B, P= 0.05) with OR = 3.0 (group C vs group A + B, 95% CI: 1.55-6.16, P < 0.001). CONCLUSION: History of term second stage of labor cesarean section is an independent risk factor for spontaneous preterm birth and for preterm rupture of membrane in the subsequent pregnancy.

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