Perinatal outcomes between immediate vs deferred selective termination in dichorionic twin pregnancies with fetal congenital anomalies: a French multicenter study.

BACKGROUND: Because selective termination for discordant dichorionic twin anomalies carries a risk of pregnancy loss, deferring the procedure until the third trimester can be considered in settings where it is legal. OBJECTIVE: To determine whether perinatal outcomes were more favorable following deferred rather than immediate selective termination. STUDY DESIGN: A French multicenter retrospective study from 2012 to 2023 on dichorionic twin pregnancies with selective termination for fetal conditions, which were diagnosed before 24 weeks gestation. Pregnancies with additional risk factors for late miscarriage were excluded. We defined 2 groups according to the intention to perform selective termination within 2 weeks after the diagnosis of the severe fetal anomaly was established (immediate selective termination) or to wait until the third trimester (deferred selective termination). The primary outcome was perinatal survival at 28 days of life. Secondary outcomes were pregnancy losses before 24 weeks gestation and preterm delivery. RESULTS: Of 390 pregnancies, 258 were in the immediate selective termination group and 132 in the deferred selective termination group. Baseline characteristics were similar in both groups. Overall survival of the healthy co-twin was 93.8% (242/258) in the immediate selective termination group vs 100% (132/132) in the deferred selective termination group (P<.01). Preterm birth <37 weeks gestation was lower in the immediate than in the deferred selective termination group (66.7% vs 20.2%; P<.01); preterm birth <28 weeks gestation and <32 weeks gestation did not differ significantly (respectively 1.7% vs 0.8%; P=.66 and 8.26% vs 11.4%; P=.36). In the deferred selective termination group, an emergency procedure was performed in 11.3% (15/132) because of threatened preterm labor, of which 3.7% (5/132) for imminent delivery. CONCLUSION: Overall survival after selective termination was high regardless of the gestational age at which the procedure was performed. Postponing selective termination until the third trimester seems to improve survival, whereas immediate selective termination reduces the risk of preterm delivery. Furthermore, deferred selective termination requires an expert center capable of performing the selective termination procedure on an emergency basis if required.

Micro-CT and high-field MRI for studying very early post-mortem human fetal anatomy at 8 weeks of gestation.

OBJECTIVE: This study involved very early post-mortem (PM) examination of human fetal anatomy at 8 weeks of gestation (WG) using whole-body multimodal micro-imaging: micro-CT and high-field MRI (HF-MRI). We discuss the potential place of this imaging in early first-trimester virtual autopsy. METHODS: We performed micro-CT after different contrast-bath protocols including diffusible iodine-based contrast-enhanced (dice) and HF-MRI with a 9.4 T machine with qualitative and quantitative evaluation and obtained histological sections. RESULTS: Nine fetuses were included: the crown-rump length was 10-24 mm and corresponded to 7 and 9 WG according to the Robinson formula. The Carnegie stages were 17-21. Dice micro-CT and HF-MRI presented high signal to noise ratio, >5, according to the Rose criterion, and for allowed anatomical phenotyping in these specimens. Imaging did not alter the histology, allowing immunostaining and pathological examination. CONCLUSION: PM non-destructive whole-body multimodal micro-imaging: dice micro-CT and HF-MRI allows for PM human fetal anatomy study as early as 8 WG. It paves the way to virtual autopsy in the very early first trimester. Obtaining a precision phenotype, even regarding miscarriage products, allows a reverse phenotyping to select variants of interest in genome-wide analysis, offering potential genetic counseling for bereaved parents.

Postnatal outcome of children with antenatal colonic hyperechogenicity.

OBJECTIVE: To evaluate the postnatal outcome of children with antenatal colonic hyperechogenicity, currently considered as a sign of lysinuria-cystinuria, but which may also be a sign of other disorders with a more severe prognosis. METHOD: We carried out a French multi-centric retrospective study via 15 Multidisciplinary Center for Prenatal Diagnosis from January 2011 to January 2021. We included pregnancies for which fetal colonic hyperechogenicity had been demonstrated. We collected the investigations performed during pregnancy and at birth as well as the main clinical features of the mother and the child. We then established the prevalence of pathologies such as lysinuria-cystinuria (LC), hypotonia-cystinuria syndrome (HC), or lysinuric protein intolerance (LPI). RESULTS: Among the 33 cases of colonic hyperechogenicity collected, and after exclusion of those lost to follow-up, we identified 63% of children with lysinuria-cystinuria, 8% with lysinuric rotein intolerance, and 4% with hypotonia-cystinuria syndrome. CONCLUSION: Management of prenatal hyperechoic colon should include a specialized consultation with a clinical geneticist to discuss further investigations, which could include invasive amniotic fluid sampling for molecular diagnosis. A better understanding of diagnoses and prognosis should improve medical counseling and guide parental decision making.

Interprofessional survey on knowledge and attitudes of midwives regarding oral health, in France.

INTRODUCTION: Oral health is essential for psychosocial well-being and general health. For expectant mothers, pregnancy increases the risk of oral diseases and has a subsequent impact on the oral health of a child once born. Midwives are in charge of pregnancy monitoring, childbirth and newborns' first days of life. They could have an important role in prevention. However, limited studies evaluating the knowledge, attitudes and practices on oral health among midwives have been conducted in Europe. METHODS: We performed a cross-sectional study using a self-administered questionnaire. Two local midwifery associations sent out the questionnaire by email and social media networks to all registered midwives and practicing in the department of Herault (n=613), between April and May 2022. Statistical analyses on quantitative data and descriptive analyses of qualitative free-text responses were performed. RESULTS: In total, 167 midwives were included. We found a lack of knowledge on many oral health topics and this was stated as the main reason that only 29% of midwives provided oral health information to their patients. Only 30% of the midwives had a training module on oral health during their initial training, and less than half of them considered the training adequate. To improve their lack of knowledge, participants expressed a preference for digital communication methods for themselves; however, they favored in-person interaction for public interventions. CONCLUSIONS: This study showed a lack of training and knowledge about oral health among midwives and a lack of oral health discussion with expectant mothers who are a high-risk population for oral diseases.

Moderate or intensive management of the active phase of second-stage labor and risk of urinary and anal incontinence: results of the PASST randomized controlled trial.

BACKGROUND: Incontinence occurs frequently in the postpartum period. Several theoretical pathophysiological models may underlie the hypothesis that different types of management of the active phase of the second stage of labor have different effects on pelvic floor muscles and thus perhaps affect urinary and anal continence. OBJECTIVE: This study aimed to evaluate the impact of "moderate pushing" on the occurrence of urinary or anal incontinence compared with "intensive pushing," and to determine the factors associated with incontinence at 6 months postpartum. STUDY DESIGN: This was a planned analysis of secondary objectives of the PASST (Phase Active du Second STade) trial, a multicenter randomized controlled trial. PASST included nulliparous women with singleton term pregnancies and epidural analgesia, who were randomly assigned at 8 cm of dilatation to either the intervention group that used "moderate" pushing (pushing only twice during each contraction, resting regularly for 1 contraction in 5 without pushing, and no time limit on pushing) or the control group following the usual management of "intensive" pushing (pushing 3 times during each contraction, with no contractions without pushing, with an obstetrician called to discuss operative delivery after 30 minutes of pushing). Data about continence were collected with validated self-assessment questionnaires at 6 months postpartum. Urinary incontinence was defined by an ICIQ-UI SF (International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form) score ≥1 and anal incontinence by a Wexner score ≥2. A separate analysis was also performed among the more severely affected women (ICIQ-UI SF ≥6 and Wexner ≥5). Factors associated with incontinence were assessed with univariate and multivariable analyses. RESULTS: Among 1618 women initially randomized, 890 (55%) returned the complete questionnaire at 6 months. The rate of urinary incontinence was 36.6% in the "moderate" pushing group vs 38.5% in the "intensive" pushing group (relative risk, 0.95; 95% confidence interval, 0.80-1.13), whereas the rate of anal incontinence was 32.2% vs 34.6% (relative risk, 0.93; 95% confidence interval, 0.77-1.12). None of the obstetrical factors studied related to the second stage of labor influenced the occurrence of urinary or anal incontinence, except operative vaginal delivery, which increased the risk of anal incontinence (adjusted odds ratio, 1.50; 95% confidence interval, 1.04-2.15). CONCLUSION: The results of the PASST trial indicate that neither moderate nor intensive pushing efforts affect the risk of urinary or anal incontinence at 6 months postpartum among women who gave birth under epidural analgesia.

Which risk score best predicts cardiovascular outcome in pregnant women with congenital heart disease?

BACKGROUND: Management of pregnancy and risk stratification in women with congenital heart diseases (CHD) are challenging, especially due to physiological haemodynamic modifications that inevitably occur during pregnancy. AIMS: To compare the accuracy of the existing pregnancy cardiovascular risk scores in prediction of maternal complications during pregnancy in CHD patients. METHOD AND RESULTS: From 2007 to 2018, all pregnant women with a CHD who delivered birth after 20 weeks of gestation were identified. The discriminating power and the accuracy of the five existing pregnancy cardiovascular risk scores [CARPREG, CARPREG II, HARRIS, ZAHARA risk scores, and modified WHO (mWHO)] were evaluated.Out of 104 pregnancies in 65 CHD patients, 29% experienced cardiovascular complications during pregnancy or post-partum. For the five scores, the observed rate of cardiovascular events was higher than the expected risk. The values of area under the ROC curve were 0.75 (0.62-0.88) for mWHO, 0.65 (0.53-0.77) for CARPREG II, 0.60 (0.40-0.80) for HARRIS, 0.59 (0.47-0.72) for ZAHARA, and 0.58 (0.43-0.73) for CARPREG. CONCLUSION: The modified WHO classification appeared to better predict cardiovascular outcome in pregnant women with CHD than the four other existing risk scores.Clinical Trial Registration: Clinicaltrials.gov: NCT04221048.

Optimization of Patient Management in the Gynecology Emergency Department Using Point-of-Care Beta hCG.

Background: Point-of-care testing (POCT) provides shorter turn-around times and, in many cases, potentially improves medical decision making. The AQT90 FLEX® benchtop immunoanalyzer (Radiometer Medical ApS, Copenhagen, Denmark) allows for the determination of beta-human chorionic gonadotropin (ßhCG) in 18 min. The main aim of this study was to evaluate the impact of measuring ßhCG using the AQT90 analyzer in the gynecology emergency department (ED) compared to the standard practice of using central laboratory blood testing on the patient length of stay (LOS). Methods: The evaluation consisted of two parts. The first one, conducted in the central laboratory, focused on the analytical performances of the AQT ßhCG assay. The second one, conducted in the ED, aimed at determining the impact of POCT ßhCG implementation on the timeframe in which ED patients require ßhCG assessment. Results: The within-lab imprecisions at the mean values of 17 and 287 IU/L were 2.7% and 3.7%, respectively. Using Deming regression (n = 60), the following equation was obtained in the central lab: AQT90 ßhCG = 1.1 Roche ßhCG­12.9 (r = 0.997). The implementation of POCT ßhCG in the ED significantly reduced patient LOS (145 (90−212) min vs. 205 (155−265) with and without AQT90, respectively, p < 0.001). At the 2 IU/L decision level, a 99.7% agreement with the Roche assay was reported (kappa statistics, 0.99). Conclusions: We confirm that the analytical qualities of the AQT 90 were in line with those obtained in the central lab. The implementation of the POCT ßhCG is associated with a shorter LOS in the ED due to the faster availability of the results and the faster decision-making possibilities.

Alternative to intensive management of the active phase of the second stage of labor: a multicenter randomized trial (Phase Active du Second STade trial) among nulliparous women with an epidural.

BACKGROUND: There is no consensus on an optimal strategy for managing the active phase of the second stage of labor. Intensive pushing could not only reduce pushing duration, but also increase abnormal fetal heart rate because of cord compression and reduced placental perfusion and oxygenation resulting from the combination of uterine contractions and maternal expulsive forces. Therefore, it may increase the risk of neonatal acidosis and the need for operative vaginal delivery. OBJECTIVE: This study aimed to assess the effect of the management encouraging "moderate" pushing vs "intensive" pushing on neonatal morbidity. STUDY DESIGN: This study was a multicenter randomized controlled trial, including nulliparas in the second stage of labor with an epidural and a singleton cephalic fetus at term and with a normal fetal heart rate. Of note, 2 groups were defined: (1) the moderate pushing group, in which women had no time limit on pushing, pushed only twice during each contraction, and observed regular periods without pushing, and (2) the intensive pushing group, in which women pushed 3 times during each contraction and the midwife called an obstetrician after 30 minutes of pushing to discuss operative delivery (standard care). The primary outcome was a composite neonatal morbidity criterion, including umbilical arterial pH of <7.15, base excess of >10 mmol/L, lactate levels of >6 mmol/L, 5-minute Apgar score of <7, and severe neonatal trauma. The secondary outcomes were mode of delivery, episiotomy, obstetrical anal sphincter injuries, postpartum hemorrhage, and maternal satisfaction. RESULTS: The study included 1710 nulliparous women. The neonatal morbidity rate was 18.9% in the moderate pushing group and 20.6% in the intensive pushing group (P=.38). Pushing duration was longer in the moderate group than in the intensive group (38.8±26.4 vs 28.6±17.0 minutes; P<.001), and its rate of operative delivery was 21.1% in the moderate group compared with 24.8% in the intensive group (P=.08). The episiotomy rate was significantly lower in the moderate pushing group than in the intensive pushing group (13.5% vs 17.8%; P=.02). We found no significant difference for obstetrical anal sphincter injuries, postpartum hemorrhage, or maternal satisfaction. CONCLUSION: Moderate pushing has no effect on neonatal morbidity, but it may nonetheless have benefits, as it was associated with a lower episiotomy rate.

Tranexamic acid for the prevention of blood loss after cesarean among women with twins: a secondary analysis of the TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery randomized clinical trial.

BACKGROUND: Although prophylactic tranexamic acid administration after cesarean delivery resulted in a lower incidence of calculated estimated blood loss of >1000 mL or red cell transfusion by day 2, its failure to reduce the incidence of hemorrhage-related secondary clinical outcomes (TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery trial) makes its use questionable. The magnitude of its effect may differ in women at higher risk of blood loss, including those with multiple pregnancies. OBJECTIVE: This study aimed to compare the effect of tranexamic acid vs placebo to prevent blood loss after cesarean delivery among women with multiple pregnancies. STUDY DESIGN: This was a secondary analysis of the TRAnexamic Acid for Preventing Postpartum Hemorrhage Following a Cesarean Delivery trial data, a double-blind, randomized controlled trial from March 2018 to January 2020 in 27 French maternity hospitals, that included 319 women with multiple pregnancies. Women with a cesarean delivery before or during labor at ≥34 weeks of gestation were randomized to receive intravenously 1 g of tranexamic acid (n=160) or placebo (n=159), both with prophylactic uterotonics. The primary outcome was a calculated estimated blood loss of >1000 mL or a red blood cell transfusion by 2 days after delivery. The secondary outcomes included clinical and laboratory blood loss measurements. RESULTS: Of the 4551 women randomized in this trial, 319 had a multiple pregnancy and cesarean delivery, and 298 (93.4%) had primary outcome data available. This outcome occurred in 62 of 147 women (42.2%) in the tranexamic acid group and 67 of 152 (44.1%) receiving placebo (adjusted risk ratio, 0.97; 95% confidence interval, 0.68-1.38; P=.86). No significant between-group differences occurred for any hemorrhage-related clinical outcomes: gravimetrically estimated blood loss, provider-assessed clinically significant hemorrhage, additional uterotonics, postpartum blood transfusion, arterial embolization, and emergency surgery (P>.05 for all comparisons). CONCLUSION: Among women with a multiple pregnancy and cesarean delivery, prophylactic tranexamic acid did not reduce the incidence of any blood loss-related outcomes.

How is functionning the Ethical Review Board « Comité d'Ethique Pour La Recherche En Obstétrique Et Gynécologie ¼ (CEROG) ?

INTRODUCTION: The French College of Gynecology and Obstetrics (CNGOF) has created an Ethical Review Board called the CEROG that aim to ensure the research projects are in conformity with the regulation and the laws, as well as to allow their publication in international scientific journals. The aim of this work was to analyze the work of this committee through the application received and to review the ethical procedures required by type of research project. METHODS: We conducted a national retrospective study of all applications from 2018 to 2021 received by the CEROG Ethical Review Board. Each application must contain a verification of conformity with the MR004 regulation, a submission form and an information form to the patients involved. At reception, the documents are anonymized and then addressed to the members of one of the two independent sections (Obstetric and Prenatal diagnosis or Gynecology and Assisted Reproductive Therapy). RESULTS: Two hundred and sixty applications were received, including 52% in the Gynecology section and 48% in the Obstetrics' section. Only 10% (14/136) and 8% (10/124) were disapproved, respectively. In total, 35% of the applications to the Gynecology section leaded to publications in scientific journals but only 23% did so in the Obstetrics section. Most publications (60.8%) were in low impact factors journals (rank D and E). CONCLUSION: The Ethical Review Board CEROG is essential to ensure the conformity of the research projects with French regulations and allow fast publication in international journals.

Arabin pessary to prevent adverse perinatal outcomes in twin pregnancies with a short cervix: a multicenter randomized controlled trial (PESSARONE).

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.

Effect of air temperature on human births, preterm births and births associated with maternal hypertension.

OBJECTIVE: We studied potential effects of outdoor air temperatures or barometric pressure on births, preterm births and births associated with maternal hypertension. METHODS: 12,269 births were retrospectively reviewed in Brussel and 25,880 in South Reunion Island. National Belgium and French weather reference centers provided outdoor air temperatures and barometric pressures from the nearest weather stations on the corresponding birthdays. Poisson regression models were used to assess if outdoor air temperatures or barometric pressure could be correlated, immediately and several days later, with the number of daily births, preterm births and births associated with hypertension. RESULTS: Outdoor air temperature was significantly correlated to the number of daily births in Brussels. For each additional degree Celsius, overall births increased by 0.4% during the same day. Four days later, overall births increased by 1.8%, preterm births by 2.6% and births associated with hypertension by 5.7%. Similar observations on numbers of daily births were reported in South Reunion Island, without reaching statistical significance (p = .08). CONCLUSION: As previously demonstrated in recent studies, increased air temperature leads progressively to higher rates of births and preterm births. An even stronger delayed effect of air temperature was observed on births associated with hypertension. This would be worth further investigating.

Use of Remifentanil Associated with Lidocaine for Feticides in Late Terminations of Pregnancy: A Randomized Clinical Trial.

INTRODUCTION: In France, performance of a termination of pregnancy is legally possible without any gestational age limit. After 22 weeks of gestation, a feticide is ethically performed using usually sufentanil and lidocaine. The aim of this study was to compare the use of remifentanil, a fast-acting morphine-derivating product, instead of sufentanil. METHODS: This 2-center randomized, controlled, single-blinded phase-III treatment trial had 2 parallel arms: an experimental group using remifentanil with lidocaine versus a control group receiving sufentanil associated with lidocaine. This trial took place over a 40-month period. The primary outcome was time to fetal asystole after lidocaine injection. The secondary outcome measures were the procedure's success rate, the rate of serious maternal side effects, and the presence of cellular or tissue modifications. RESULTS: The study included 66 women, randomized into 2 groups of similar size and characteristics. Time to fetal asystole did not differ significantly between the groups, with a delay of 4 min (Q1-Q3, 2-11) in the sufentanil group and 4 min (Q1-Q3, 1-10) in the remifentanil group (p = 0.84). Similarly, the success rate of the procedure did not differ significantly. Fetal asystole was procured in <2 min and persisted >1 min for 16 (25.8%) women in our total population: 7 (22.5%) in the sufentanil group and 9 (29.0%) in the remifentanil group, p = 0.77. No severe maternal side effects were observed. Among the 49 fetopathological examinations performed, the few tissue and cell modifications observed did not cause any interpretation difficulties in either group. DISCUSSION/CONCLUSION: Use of remifentanil instead of sufentanil for feticide procedure did not improve time to fetal asystole. No harmful effect was observed for either maternal tolerance or interpretation of the histologic slides.

Guidelines for the management of women with severe pre-eclampsia.

OBJECTIVE: To provide national guidelines for the management of women with severe pre-eclampsia. 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 emphasised. METHODS: The last SFAR and CNGOF guidelines on the management of women with severe pre-eclampsia were 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 analysed 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 pre-eclampsia.

Should prenatal chromosomal microarray analysis be offered for isolated fetal growth restriction? A French multicenter study.

BACKGROUND: Compared with standard karyotype, chromosomal microarray analysis improves the detection of genetic anomalies and is thus recommended in many prenatal indications. However, evidence is still lacking on the clinical utility of chromosomal microarray analysis in cases of isolated fetal growth restriction. OBJECTIVE: This study aimed to estimate the proportion of copy number variants detected by chromosomal microarray analysis and the incremental yield of chromosomal microarray analysis compared with karyotype in the detection of genetic abnormalities in fetuses with isolated fetal growth restriction. STUDY DESIGN: This retrospective study included all singleton fetuses diagnosed with fetal growth restriction and no structural ultrasound anomalies and referred to 13 French fetal medicine centers over 1 year in 2016. Fetal growth restriction was defined as an estimated fetal weight of

Tranexamic Acid for the Prevention of Blood Loss after Cesarean Delivery.

BACKGROUND: Prophylactic administration of tranexamic acid has been associated with reduced postpartum blood loss after cesarean delivery in several small trials, but evidence of its benefit in this clinical context remains inconclusive. METHODS: In a multicenter, double-blind, randomized, controlled trial, we assigned women undergoing cesarean delivery before or during labor at 34 or more gestational weeks to receive an intravenously administered prophylactic uterotonic agent and either tranexamic acid (1 g) or placebo. The primary outcome was postpartum hemorrhage, defined as a calculated estimated blood loss greater than 1000 ml or receipt of a red-cell transfusion within 2 days after delivery. Secondary outcomes included gravimetrically estimated blood loss, provider-assessed clinically significant postpartum hemorrhage, use of additional uterotonic agents, and postpartum blood transfusion. RESULTS: Of the 4551 women who underwent randomization, 4431 underwent cesarean delivery, 4153 (93.7%) of whom had primary outcome data available. The primary outcome occurred in 556 of 2086 women (26.7%) in the tranexamic acid group and in 653 of 2067 (31.6%) in the placebo group (adjusted risk ratio, 0.84; 95% confidence interval [CI], 0.75 to 0.94; P = 0.003). There were no significant between-group differences in mean gravimetrically estimated blood loss or in the percentage of women with provider-assessed clinically significant postpartum hemorrhage, use of additional uterotonic agents, or postpartum blood transfusion. Thromboembolic events in the 3 months after delivery occurred in 0.4% of women (8 of 2049) who received tranexamic acid and in 0.1% of women (2 of 2056) who received placebo (adjusted risk ratio, 4.01; 95% CI, 0.85 to 18.92; P = 0.08). CONCLUSIONS: Among women who underwent cesarean delivery and received prophylactic uterotonic agents, tranexamic acid treatment resulted in a significantly lower incidence of calculated estimated blood loss greater than 1000 ml or red-cell transfusion by day 2 than placebo, but it did not result in a lower incidence of hemorrhage-related secondary clinical outcomes.

Corpus luteum score, a simple Doppler examination to prognose early pregnancies.

OBJECTIVES: In early pregnancies, miscarriages and inconclusive ultrasound scans considering location and viability are very common. In several previous studies, serum progesterone levels predicted viability of pregnancy and, in recent ones, failed Pregnancies of Unknown Location (PUL), completion of miscarriage and complications. Corpus luteum, secreting progesterone in early pregnancy, was less studied. Some publications showed correlations between corpus luteum aspects and diagnosis of miscarriage but it was not evaluated for other outcomes in early pregnancy, such as failed PUL, completion of miscarriage or complications. We aimed to assess if Doppler examination of corpus luteum could also predict all these outcomes: failed PUL, diagnosis and completion of miscarriages and complications. STUDY DESIGN: A single operator prospectively described and/or collected pictures of Doppler signal in the wall of the corpus luteum at most consultations in our early pregnancy unit and established a three-level score. All suspected or confirmed non-viable pregnancies with this score or/and serum progesterone levels were registered retrospectively. With logistic regressions, AIC/BIC, likelihood ratios, ROC curves, Mann-Whitney and Fisher exact tests, we evaluated the ability of the score, alone, to predict failed PUL, diagnosis and completion of miscarriages and the complications, and, combined, to improve previously published predictions. RESULTS: From 277 included pregnancies, 186 (67.1 %) miscarried. Of these, 159/186 (85.5 %) fully evacuated without surgery: 114/186 (61.3 %) within 20 days after the first diagnosis and 45/186 (24.2 %) after more than 20 days. Twenty-seven patients (14.5 %) underwent surgical evacuation, including ten complications, five haemorrhages and five suspected infections. Logistic regression correlated strongly the corpus luteum score with failed PUL (p < 0.0001) and miscarriages (p < 0.0001). Moreover, rates of complications and swift non-surgical completions of miscarriage were respectively 0 % and 92 % with scores of 0, versus 6 % and 44 % with scores of 1, versus 16 % and 0 % with scores of 2. Combined with serum progesterone levels, this score improved most predictions. Adding parity or history of miscarriage in predictive models even increased these performances. CONCLUSIONS: Corpus luteum score, alone, can predict failed PUL, diagnosis and completion of miscarriages and their complications. Combining this score with other factors (mainly serum progesterone levels) improves most predictions.
