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 A video abstract of this article is available online here.

Objective: To investigate the association between absent or reversed end-diastolic flow (ARED) on umbilical artery Doppler ultrasound and poor neurological outcome at 2 years of age after very preterm birth associated with suspected fetal growth restriction (FGR) or maternal hypertensive disorders.Methods: The study population comprised all very preterm (22-31 completed weeks) singleton pregnancies delivered because of suspected FGR and/or maternal hypertensive disorders that had umbilical artery Doppler and 2-year follow-up available included in EPIPAGE-2, a prospective, nationwide, population-based cohort of preterm births in France in 2011. Univariate and two-level multivariable logistic regression analyses were used to assess the association of ARED in the umbilical artery, as compared with normal or reduced end-diastolic flow, with severe or moderate neuromotor and/or sensory disability and with an Ages and Stages Questionnaire (ASQ) score below a threshold. This was defined as a score more than 2 SD below the mean in any of the five domains, at age 2, adjusting for gestational age at delivery. ASQ is used to identify children at risk of developmental delay requiring reinforced follow-up and further evaluation. Descriptive statistics and bivariate tests were weighted according to the duration of the inclusion periods.Results: The analysis included 484 children followed up at 2 years of age, for whom prenatal umbilical artery Doppler ultrasound was available. Among them, 8/484 (1.6%) had severe or moderate neuromotor and/or sensory disability, and 156/342 (45.4%) had an ASQ score below the threshold. Compared with normal or reduced end-diastolic flow in the umbilical artery (n = 305), ARED (n = 179) was associated with severe or moderate neuromotor and/or sensory disability (adjusted odds ratio (OR), 11.3; 95% CI, 1.4-93.2) but not with an ASQ score below the threshold (adjusted OR, 1.2; 95% CI, 0.8-1.9).Conclusion: Among children delivered before 32 weeks of gestation due to suspected FGR and/or maternal hypertensive disorder who survived until 2 years of age, prenatal ARED in the umbilical artery was associated with a higher incidence of severe or moderate neuromotor and/or sensory disability.

The authors compare the national guidelines on postpartum haemorrhage (PH) of various English-speaking countries such as the Royal College of Obstetrician and Gynaecologists (RCOG) and the American College of Obstetricians and Gynecologists (ACOG). Topics discussed include the definitions of PPH and severe PPH after vaginal delivery and the benefits of comparing the guidelines for clinicians and clinical research.

Objectives: To investigate the efficacy of antenatal corticosteroid (ACS) therapy on short-term neonatal outcomes in preterm twins, and further document the influence of the ACS-to-delivery interval.Design: EPIPAGE-2 is a nationwide observational multicentre prospective cohort study of neonates born between 22 and 34 completed weeks of gestation.Setting: All French maternity units, except in a single administrative region, between March and December 2011.Population: A total of 750 twin neonates born between 24 and 31 weeks of gestation.Methods: Exposure to ACSs was examined in four groups: single complete course, with an ACS administration-to-delivery interval of ≤7 days; single complete course, with an ACS-to-delivery interval of >7 days; repeated courses; or no ACS treatment.Main Outcome Measures: Neonatal outcomes analysed were severe bronchopulmonary dysplasia, periventricular leukomalacia or intraventricular haemorrhage grade III/IV, in-hospital mortality, and a composite indicator of severe outcomes.Results: Compared with no ACSs, in multivariable analysis, a single course of ACSs with an administration-to-delivery interval of ≤7 days was significantly associated with a reduced rate of periventricular leukomalacia or intraventricular haemorrhage grade III/IV (aOR 0.2; CI 95% 0.1-0.5), in-hospital mortality (0.3; 0.1-0.6), and the composite indicator (0.1; 0.1-0.3), whereas a single course of ACDs with an administration-to-delivery interval of >7 days did not significantly reduce the frequency of in-hospital mortality (0.7; 0.3-1.8). No significant differences in terms of benefit or risk were found when comparing repeated courses with a single complete course.Conclusion: In preterm twins, a single complete course of antenatal corticosteroids was associated with an improvement of severe neurological outcome, whereas reduced in-hospital mortality was seen only when the ACS-to-delivery interval was ≤7 days.Tweetable Abstract: A single complete course of antenatal steroids reduced severe neurological morbidity in preterm twins (24-31 weeks).

Background: Titanium dioxide (TiO2) is broadly used in common consumer goods, including as a food additive (E171 in Europe) for colouring and opacifying properties. The E171 additive contains TiO2 nanoparticles (NPs), part of them being absorbed in the intestine and accumulated in several systemic organs. Exposure to TiO2-NPs in rodents during pregnancy resulted in alteration of placental functions and a materno-foetal transfer of NPs, both with toxic effects on the foetus. However, no human data are available for pregnant women exposed to food-grade TiO2-NPs and their potential transfer to the foetus. In this study, human placentae collected at term from normal pregnancies and meconium (the first stool of newborns) from unpaired mothers/children were analysed using inductively coupled plasma mass spectrometry (ICP-MS) and scanning transmission electron microscopy (STEM) coupled to energy-dispersive X-ray (EDX) spectroscopy for their titanium (Ti) contents and for analysis of TiO2 particle deposition, respectively. Using an ex vivo placenta perfusion model, we also assessed the transplacental passage of food-grade TiO2 particles. Results: By ICP-MS analysis, we evidenced the presence of Ti in all placentae (basal level ranging from 0.01 to 0.48 mg/kg of tissue) and in 50% of the meconium samples (0.02–1.50 mg/kg), suggesting a materno-foetal passage of Ti. STEM-EDX observation of the placental tissues confirmed the presence of TiO2-NPs in addition to iron (Fe), tin (Sn), aluminium (Al) and silicon (Si) as mixed or isolated particle deposits. TiO2 particles, as well as Si, Al, Fe and zinc (Zn) particles were also recovered in the meconium. In placenta perfusion experiments, confocal imaging and SEM-EDX analysis of foetal exudate confirmed a low transfer of food-grade TiO2 particles to the foetal side, which was barely quantifiable by ICP-MS. Diameter measurements showed that 70 to 100% of the TiO2 particles recovered in the foetal exudate were nanosized. Conclusions: Altogether, these results show a materno-foetal transfer of TiO2 particles during pregnancy, with food-grade TiO2 as a potential source for foetal exposure to NPs. These data emphasize the need for risk assessment of chronic exposure to TiO2-NPs during pregnancy. [ABSTRACT FROM AUTHOR]

Objective: In order to identify women at high risk of pre-eclampsia and offer them aspirin prophylactic treatment, the Fetal Medicine Foundation (FMF) recommends a first-trimester screening test. The commonly used threshold for aspirin administration is a risk >1/100, which implies treating an important number of patients. We aimed to assess the use of this strategy with a more restrictive threshold: risk >1/70 and evaluate the impact of this strategy on the prevalence of pre-eclampsia with premature delivery in nulliparous women., Methods: A before-and-after cohort study conducted from 01/09/2014 to 01/12/2018, including nulliparous women undergoing first-trimester ultrasound at the University Hospital of Toulouse. Between 09/2014 and 09/2016 ("before cohort"), women did not undergo pre-eclampsia screening. Between 01/2017 and 12/2018 ("after cohort"), women underwent targeted pre-eclampsia screening using the FMF algorithm, and those with a risk >1/70 received 100mg aspirin. The primary outcome was pre-eclampsia with premature delivery. A univariate and then a multivariate analysis were performed to take into account potential confounding factors., Results: Among the 1030 women of the before cohort, 17 women (1.7%) experienced pre-eclampsia with premature delivery, compared to 8 women (1.3%) among the 629 of the after cohort, with no significant difference between the two groups (Adjusted Odd Ratio (95%CI)=0.73 [0.31-1.74]). In the after cohort, 18 women (2.9%) had a risk greater than 1/70 and therefore received aspirin. According to the FMF screening test, 89 women (14.1%) had a risk>1/100, which is the usual threshold for prescribing aspirin for prophylaxis. This means that 71 women had a risk greater than 1/100 but less than 1/70 and therefore did not receive aspirin in this study, even though they would have received aspirin at the usual threshold., Conclusions: The screening and prevention strategy for pre-eclampsia using restrictive thresholds did not decrease the rate of preeclampsia with premature delivery., (Copyright © 2024 Elsevier Masson SAS.

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., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

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., (© 2023 The Authors.
