Successful pregnancy after 10 consecutive failures in a liver transplant patient with advanced kidney failure.

We report a successful, albeit complicated pregnancy with a live-born healthy baby at 28 weeks' gestation, after 10 pregnancy failures, in a 39-year-old patient with a history of liver transplantation and chronic kidney disease with hypertension and proteinuria. Multidisciplinary management (obstetrician, nephrologist and hepatology transplant specialist) allowed close monitoring, adaptation of immunosuppressive treatments and strict control of fetal growth. The onset of preeclampsia at 28 weeks' gestation led to a cesarean section, resulting in the birth of a healthy 830 g boy, with subsequent normal development. Following pregnancy, the patient experienced liver transplant rejection, which resolved after adapting immunosuppressive drugs. No deterioration in kidney function was observed in the year following delivery.

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.

Intimate partner violence as a risk factor for venous thromboembolism in women on combined oral contraceptives: An international matched case-control study.

BACKGROUND: Intimate partner violence (IPV) targeting women is probably underestimated during a woman's lifetime. Venous thromboembolism (VTE) is a multifactorial disease associated with haemostasis-activating conditions. Minor injuries can trigger VTE. OBJECTIVES: We aimed to look for an association between VTE and IPV in women taking combined oral contraceptives (COCs) METHODS: We performed a multicentric, international, matched case-control study. Patients were women with a first VTE associated with COC intake. Controls were women taking COCs undergoing regular gynaecological check-ups. Patients and Controls were matched for country, age, length of COC intake and type (997 pairs). IPV was evaluated using the WAST self-administrated questionnaire. RESULTS: IPV, defined as a WAST score value at least 5, was diagnosed in 33 Controls (3.3 %) and 109 patients (10.9 %), conditional odds ratio (OR): 3.586, 95 % confidence interval (2.404-5.549), p < 0.0001. After multivariate analysis, the adjusted OR was 3.720 (2.438-5.677), p < 0.0001. Sensitivity analysis using increasing WAST score thresholds confirmed the association. CONCLUSIONS: A first VTE in women taking COCs is associated with IPV. This association can have strong human consequences but also raises significant medical issues, for instance on the haemorrhagic risk of anticoagulant treatments in abused women. Pathophysiological studies are warranted.

Fetal intestinal loop dilatation: Follow-up and outcome of a series of 133 consecutive cases (the DILDIG study).

OBJECTIVES: To define the prognostic markers of fetal dilated bowel loops. METHODS: National non-interventional study of 133 consecutive prenatal observations of dilated loops including ultrasound examinations, complementary laboratory tests, magnetic resonance imaging (MRI), outcomes, and postnatal diagnosis. RESULTS: One hundred twenty seven cases were classified according to outcome: Group 1, very severe (n = 43), Group 2, children needing specific care (n = 39), and Group 3, healthy children (n = 45). Prenatal ultrasound scan suggested duodenal obstruction in 30 cases, small bowel obstruction in 81, colonic obstruction in 11, and diffuse dilatation in 5. Diameter of dilated loops did not significantly differ between the groups. A poor prognosis was significantly associated with duodenal obstruction, genetic anomalies (53% vs. 21.8%), including aneuploidies or CFTR gene mutations and abnormal amniotic fluid biochemistry (86.4% vs. 38.7%). A good prognosis was associated with regression of dilatation and normal MRI. CONCLUSION: In this study, postnatal outcomes for fetuses with intestinal dilatation were best predicted by assessing the level of obstruction with prenatal ultrasound and MRI, determining the presence of associated malformations, amniotic fluid biochemical and genetic testing, and monitoring for regression of bowel dilatation. These results should help inform future guidelines on the prenatal and neonatal management of congenital intestinal obstruction.

Combined oral contraceptive-associated venous thromboembolism revealing an antiphospholipid syndrome: International retrospective study of outcomes.

INTRODUCTION: Limitations in the data used to define thromboprophylaxis for patients with antiphospholipid antibodies (aPLAbs) and thrombosis include uncertainties after an initial provoked venous thromboembolic event (VTE). We aimed to study such cases associated with combined oral contraceptive (COC) intake. METHODS: We retrospectively analysed thrombotic outcomes after a first COC-associated VTE and positive aPLAbs, with a low risk HERDOO2 score, on low-dose aspirin (LDA) secondary thromboprophylaxis, seen from 2010 to 2021 in 3 tertiary referral centres, one in France and 2 in Russia. Data from 264 patients (distal deep vein thrombosis DVT: 62.9 %), cumulating in 1327.7 patient-years of observation, were collected. RESULTS: There were 22 cases of thrombosis: 16 distal DVTs, 3 proximal, 1 pulmonary embolism (PE) and 2 transient ischemic attacks. Recurrence rate was 1.66 per 100 patient-years (p-y; 95 % CI: 0.96-2.33). No major bleeding occurred. Risk factors affecting recurrence-free survival were the time between first COC intake and VTE (p < 0.0001; the shortest, the lower), proximal DVT (p = 0.021), active smoking (p = 0.039), an associated systemic disease (p = 0.043) and circulating monocyte counts (p = 0.001). CONCLUSIONS: We observed a low risk of recurrence which was modulated by classical risk factors for VTE. These observational data may provide clues for future randomized controlled trials.

Soluble CD146 is increased in preeclampsia and interacts with galectin-1 to regulate trophoblast migration through VEGFR2 receptor.

OBJECTIVE: To explore the regulatory role of soluble CD146 (sCD146) and its interaction with galectin-1 (Gal1) in placenta-mediated complications of pregnancy. DESIGN: Prospective pilot and experimental studies. SETTING: University-affiliated hospital and academic research laboratory. PATIENT(S): One hundred fifteen women divided into three groups: 30 healthy, nonpregnant women, 50 women with normal pregnancies, and 35 with placenta-mediated pregnancy complications. INTERVENTION(S): Wound-healing experiments were conducted to study trophoblast migration. MAIN OUTCOME MEASURE(S): Quantification of sCD146 and Gal1 by enzyme-linked immunosorbent assay. Analysis of trophoblast migration by wound closure. RESULT(S): Concomitant detection of sCD146 and Gal1 showed lower sCD146 and higher Gal1 concentrations in women with normal pregnancies compared with nonpregnant women. In addition, follow-up of these women revealed a decrease in sCD146 associated with an increase in Gal1 throughout pregnancy. In contrast, in women with preeclampsia, we found significantly higher sCD146 concentrations compared with women with normal pregnancies and no modification of Gal1. We emphasize the opposing effects of sCD146 and Gal, since, unlike Gal1, sCD146 inhibits trophoblast migration. Moreover, the migratory effect of Gal1 was abrogated with the use of an anti-CD146 blocking antibody or the use of small interfering RNA to silence VEGFR2 expression. This suggests that trophoblast migration is mediated though the interaction of Gal1 with CD146, further activating the VEGFR2 signaling pathway. Significantly, sCD146 blocked the migratory effects of Gal1 on trophoblasts and inhibited its secretion, suggesting that sCD146 acts as a ligand trap. CONCLUSION(S): Soluble CD146 could be proposed as a biomarker in preeclampsia and a potential therapeutic target. CLINICAL TRIAL REGISTRATION NUMBER: NCT 01736826.

Pregnancy after Combined Oral Contraceptive-Associated Venous Thromboembolism: An International Retrospective Study of Outcomes.

BACKGROUND: Few data are available on thrombotic outcomes during pregnancy and puerperium occurring after an initial provoked venous thromboembolic (VTE) event. OBJECTIVES: To describe thrombotic outcomes during pregnancy after a first combined oral contraceptive (COC)-associated VTE and the factors associated with recurrence. METHODS: This was an international multicentric retrospective study on patients referred for thrombophilia screening from January 1, 2010 to January 1, 2021 following a first COC-associated VTE, including women with neither inherited thrombophilia nor antiphospholipid antibodies and focusing on those who had a subsequent pregnancy under the same thromboprophylaxis treatment. Thrombotic recurrences during pregnancy and puerperium as well as risk factors for recurrence were analyzed. RESULTS: We included 2,145 pregnant women. A total of 88 thrombotic events, 58 antenatal and 29 postnatal, occurred, mostly during the first trimester of pregnancy and the first 2 weeks of puerperium. Incidence rates were 49.6 (37-62) per 1,000 patient-years during pregnancy and 118.7 (78-159) per 1,000 patient-years during puerperium. Focusing on pulmonary embolism, incidence rates were 1.68 (1-4) per 1,000 patient-years during pregnancy and 65.5 (35-97) per 1,000 patient-years during puerperium.Risk factors for antenatal recurrences were maternal hypercholesterolemia and birth of a very small-for-gestational-age neonate. A risk factor for postnatal recurrence was the incidence of preeclampsia. CONCLUSION: Our multicentric retrospective data show significant rates of VTE recurrence during pregnancy and puerperium in women with a previous VTE event associated with COC, despite a unique low-molecular-weight heparin-based thromboprophylaxis. These results may provide benchmarks and valuable information for designing future randomized controlled trials.

Extending the prenatal Noonan's phenotype by review of ultrasound and autopsy data.

OBJECTIVES: The antenatal phenotypic spectrum of Noonan Syndrome (NS) requires better characterization. METHODS: This multicenter retrospective observational included 16 fetuses with molecularly confirmed NS admitted for fetopathological examination between 2009 and 2016. RESULTS: Among 12 pathogenic variants (PV) in PTPN11 (80%), 5 (42%) fell between position c.179 and c.182. Ultrasound showed increased nuchal translucency (n = 13/16, 93%), increased nuchal fold after 15 weeks of gestation (n = 12/16, 75%), pleural effusions (n = 11/16, 69%), polyhydramnios (n = 9/16, 56%), hydrops (n = 7/16, 44%), cardiovascular (n = 6/16, 38%) and cerebral (n = 4/16, 25%) anomalies. Fetopathological examination found dysmorphic features in all cases, cardiovascular anomalies (n = 12/15, 80%), pulmonary hypoplasia (n = 10/15, 67%), effusions (n = 7/15, 47%) and neuropathological anomalies (n = 5/15, 33%). Hydrops was significantly (p = 0.02) more frequent in the four fetuses with RIT1, NRAS and RAF1 PV versus the 12 fetuses with PTPN11 PV. CONCLUSIONS: Increased nuchal translucency and nuchal fold is common in NS. Noonan Syndrome antenatal phenotype showed high in utero fetal death, hydrops, prenatal pleural effusion and pulmonary hypoplasia, although the inclusion of only deceased fetuses will have selected more severe phenotypes. Non-specific cardiovascular and neurological abnormalities should be added to NS antenatal phenotype. Next generation sequencing will help detect more genotypes, clarifying the prenatal phenotype and identifying genotype-phenotype correlations.

Terminal 6q deletions cause brain malformations, a phenotype mimicking heterozygous DLL1 pathogenic variants: A multicenter retrospective case series.

OBJECTIVE: Terminal 6q deletion is a rare genetic condition associated with a neurodevelopmental disorder characterized by intellectual disability and structural brain anomalies. Interestingly, a similar phenotype is observed in patients harboring pathogenic variants in the DLL1 gene. Our study aimed to further characterize the prenatal phenotype of this syndrome as well as to attempt to establish phenotype-genotype correlations. METHOD: We collected ultrasound findings from 22 fetuses diagnosed with a pure 6qter deletion. We reviewed the literature and compared our 22 cases with 14 fetuses previously reported as well as with patients with heterozygous DLL1 pathogenic variants. RESULTS: Brain structural alterations were observed in all fetuses. The most common findings (>70%) were cerebellar hypoplasia, ventriculomegaly, and corpus callosum abnormalities. Gyration abnormalities were observed in 46% of cases. Occasional findings included cerebral heterotopia, aqueductal stenosis, vertebral malformations, dysmorphic features, and kidney abnormalities. CONCLUSION: This is the first series of fetuses diagnosed with pure terminal 6q deletion. Based on our findings, we emphasize the prenatal sonographic anomalies, which may suggest the syndrome. Furthermore, this study highlights the importance of chromosomal microarray analysis to search for submicroscopic deletions of the 6q27 region involving the DLL1 gene in fetuses with these malformations.

Vital NETosis vs. suicidal NETosis during normal pregnancy and preeclampsia.

Background: NETosis occurs in the context of infection or inflammation and results in the expulsion of decondensed DNA filaments called NETs (Neutrophil Extracellular Traps) into the extracellular environment. NETosis activates coagulation and contributes to the thrombotic risk of inflammatory diseases. To date, two mechanisms of NETosis have been identified: suicidal NETosis, in which neutrophils die after expelling the filaments; and vital NETosis, in which expulsion appears without altering the membrane. Human pregnancy is associated with a mild pro-inflammatory state, which is increased in the event of complications such as preeclampsia (PE). NETosis has been observed in these situations, but the mechanism of its production has not yet been studied. The aim of our study was to evaluate the balance of vital vs. suicidal NETosis in normal pregnancy and in PE. Patients/Methods: Neutrophils from healthy volunteers were stimulated with plasma from normal pregnancies (n = 13) and from women developing preeclampsia (n = 13). Immunofluorescent labelling was performed to determine the percentages and origin of NETs in both groups. Inhibition with suicidal or vital NETosis inhibitors was also performed to validate our results. Results: We found a significant increase in NETs in women with PE compared to women with normal pregnancies. We showed that vital and non-vital NETosis are present in normal and preeclamptic pregnancies. We demonstrated that the higher proportion of NETs observed in PE was due to non-vital NETosis whose main component is represented by suicidal NETosis. Discussion: These results suggest the important part of non-vital NETosis in the pathophysiology of PE.

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.

Assessment of All-Cause Cancer Incidence Among Individuals With Preeclampsia or Eclampsia During First Pregnancy.

Importance: Preeclampsia or eclampsia (preeclampsia/eclampsia) during pregnancy induces major physiological changes and may be associated with specific cancer occurrences in later life. The current data regarding the association between preeclampsia/eclampsia and cancer are heterogeneous, and cancer risk after preeclampsia/eclampsia could be different depending on the organ. These uncertainties warrant reexamination of the association between preeclampsia/eclampsia and the risk of cancer overall and by specific cancer type. Objective: To evaluate the risk of cancer, overall and by type, after preeclampsia/eclampsia during a first pregnancy. Design, Setting, and Participants: This retrospective cohort study used data from the French hospital discharge database to identify all female individuals who had a pregnancy-associated hospitalization between January 1, 2010, and December 31, 2019. To allow a minimum of 2 years for the detection of medical history, individuals with a first detected pregnancy before January 1, 2012, were excluded, as were those with a cancer-associated hospitalization before or during their first detected pregnancy. Exposures, comorbidities, and occurrences of cancer were evaluated using data from the medico-administrative registers of hospitalizations in private and public French hospitals. Cox proportional hazards models were used to analyze cancer risk according to the occurrence of preeclampsia/eclampsia during first pregnancy. Exposures: Preeclampsia/eclampsia-associated hospitalization during the first detected pregnancy. Main Outcomes and Measures: The primary outcome was the incidence of cancer, including myelodysplastic or myeloproliferative diseases, after a first pregnancy with and without preeclampsia/eclampsia. Results: After exclusions, a total of 4 322 970 female individuals (mean [SD] age at first detected pregnancy, 29.6 [6.2] years) with and without preeclampsia/eclampsia during their first pregnancy were included. Of those, 45 523 individuals (1.1%) were diagnosed with preeclampsia/eclampsia during their first detected pregnancy. The maximum follow-up was 8 years, during which 29 173 individuals (0.7%) were diagnosed with cancer. No significant difference in overall cancer incidence was found between those with and without preeclampsia/eclampsia during their first pregnancy (adjusted hazard ratio [AHR], 0.94; 95% CI, 0.84-1.05). Preeclampsia/eclampsia was associated with an increase in the risk of myelodysplastic syndromes or myeloproliferative diseases (AHR, 2.43; 95% CI, 1.46-4.06) and kidney cancer (AHR, 2.19; 95% CI, 1.09-4.42) and a decrease in the risk of breast cancer (AHR, 0.79; 95% CI, 0.62-0.99) and cervical cancer (AHR, 0.75; 95% CI, 0.58-0.96). Conclusions and Relevance: In this study, a history of preeclampsia/eclampsia during first pregnancy was associated with an increase in the incidence of myelodysplastic or myeloproliferative diseases and kidney cancer and a decrease in the incidence of cervical and breast cancers. These associations might reflect an underlying common factor among preeclampsia/eclampsia and these pathologies and/or an association between preeclampsia/eclampsia and the development of these cancers.

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

NETosis Markers in Pregnancy: Effects Differ According to Histone Subtypes.

NETosis is an innate immune response occurring after infection or inflammation: activated neutrophils expel decondensed DNA in complex with histones into the extracellular environment in a controlled manner. It activates coagulation and fuels the risk of thrombosis. Human pregnancy is associated with a mild proinflammatory state characterized by circulatory neutrophil activation which is further increased in complicated pregnancies, placenta-mediated complications being associated with an increased thrombotic risk. This aberrant activation leads to an increased release of nucleosomes in the blood flow. The aim of our study was to initially quantify nucleosome-bound histones in normal pregnancy and in placenta-mediated complication counterpart. We analyzed the role of histones on extravillous trophoblast function. Circulating nucleosome-bound histones H3 (Nu.QH3.1, Nu.QH3PanCit, Nu.QH3K27me3) and H4 (Nu.QH4K16Ac) were increased in complicated pregnancies. In vitro using the extravillous cell line HTR-8/SVNeo, we observed that free recombinant H2B, H3, and H4 inhibited migration in wound healing assay, but only H3 also blocked invasion in Matrigel-coated Transwell experiments. H3 and H4 also induced apoptosis, whereas H2B did not. Finally, the negative effects of H3 on invasion and apoptosis could be restored with enoxaparin, a low-molecular-weight heparin (LMWH), but not with aspirin. Different circulating nucleosome-bound histones are increased in complicated pregnancy and this would affect migration, invasion, and induce apoptosis of extravillous trophoblasts. Histones might be part of the link between the risk of thrombosis and pregnancy complications, with an effect of LMWH on both.

Announcing fetal pathology: Challenges encountered by physicians and potential role of simulation in training for breaking bad news.

BACKGROUND: Informing couples about the diagnosis of severe fetal pathologies is part of the daily routine in fetal medicine. This situation is usually complex and can put untrained professionals in an uncomfortable position. The aim of this study was to assess the perception of health care professionals when faced with the need to announce a fetal pathology in order to target their training gaps in this domain. MATERIALS AND METHODS: A questionnaire was created and disseminated on a national level among physicians practicing or collaborating with the multidisciplinary centers of prenatal diagnosis in France. The questionnaire focused on the difficulties encountered by practitioners when announcing fetal pathologies, and their potential interest in simulation sessions regarding the delivery of bad news. RESULTS: 193 participants filled the questionnaire. 65 % report not receiving any theoretical courses in this field during their initial training, 49 % admit feeling uncomfortable when a fetal anomaly needs to be announced, 79.5 % think that role-play could help them, 87.5 % believe that training sessions in communication skills would help improve their methods and 73.1 % support teaching the delivery of bad news by simulation sessions. CONCLUSION: This survey illustrates the significance of announcing a fetal pathology for fetal medicine professionals. Many of them report not being properly trained to cope with this situation and would like to improve with a more practical way of teaching. Simulation would be the ideal educational tool to meet this demand.

Placenta-mediated complications: Nucleosomes and free DNA concentrations differ depending on subtypes.

BACKGROUND: Placenta-mediated pregnancy complications generate short- and long-term adverse medical outcomes for both the mother and the fetus. Nucleosomes and free DNA (fDNA) have been described in patients suffering from a wide range of inflammatory conditions. OBJECTIVE: The objective of our study was to compare nucleosomes and fDNA circulating levels during pregnancy and particularly in women developing a placenta-mediated complication according to the subtype (preeclampsia or intrauterine growth restriction) (NCT01736826). PATIENTS/METHODS: A total of 115 women were prospectively included in the study across three groups: 30 healthy non-pregnant women, 50 with normal pregnancy, and 35 with a complicated pregnancy. Blood samples were taken up to every 4 weeks for several women with normal pregnancy and nucleosomes and fDNA were quantified using enzyme-linked immunosorbent assay and quantitative polymerase chain reaction, respectively. RESULTS: We show that nucleosomes and fDNA concentrations significantly increase during normal pregnancy, with concentrations at delivery differing between the two groups. Interestingly, we show that concentrations differ according to the type of placenta-mediated complications, with higher levels in preeclampsia compared to intrauterine growth restriction. CONCLUSIONS: These data suggest that nucleosomes and fDNA may be additional actors participating in placenta-mediated pregnancy complications.

Prenatal ultrasound diagnosis of cleft palate without cleft lip, the new ultrasound semiology.

OBJECTIVES: The aim of this study was to define the prenatal ultrasound semiology of cleft palate without cleft lip using 3D visualization of the fetal palate. METHODS: A prospective longitudinal study was performed in our University Hospital Center from 2011 to 2018. The fetal secondary palate was studied in 3D, starting with 2D axial transverse ultrasound view. We defined a cleft palate as a disruption of the horizontal plate of the palatine bone of the secondary palate. Prenatal findings were correlated to anatomic postnatal examinations performed by a paediatric plastic surgeon. RESULTS: Forty-three cases of cleft palate without cleft lip were prenatally diagnosed, of whom 34 were associated with malformations. We defined four types of disruptive appearances: isolated nonvisualization of the posterior nasal spine; partial-disruption or cleft velum; complete disappearance or V-shaped cleft palate; and complete disappearance or U-shaped cleft palate. The adjusted kappa coefficient, between prenatal and postnatal evaluation, was 0.88 (95% CI: 0.79-0.97), corresponding to an excellent agreement. CONCLUSIONS: Using a strictly axial transverse ultrasound view, visualization of the secondary fetal palate enables to diagnose a cleft palate without cleft lip. This method offers a prenatal anatomic classification of cleft palate with a high level of concordance to postnatal findings.

Balloon catheter vs oxytocin alone for induction of labor in women with a previous cesarean section: A randomized controlled trial.

INTRODUCTION: The aim of this study was to compare the efficacy and maternal-neonatal morbidity between balloon catheter and oxytocin for induction of labor in women with a previous cesarean section and an unfavorable cervix. MATERIAL AND METHODS: This open-label randomized controlled trial took place in seven French hospitals. Inclusion criteria were medical indication for labor induction in pregnant women, ≥37 weeks, with lower segment cesarean section, Bishop score ≤4, no pre-labor rupture of membranes, singleton fetus in cephalic presentation. Women were allocated randomly to induction with a 50-mL balloon catheter for 12 hours or a low-dose oxytocin infusion. Primary outcome was the rate of vaginal birth. Secondary outcomes were maternal and neonatal complications. RESULTS: The study enrolled 204 women from 26 December 2010 to 31 December 2013: 101 were allocated to receive balloon catheter and 103 to oxytocin. Vaginal birth rate was 50% (n = 51) in the balloon catheter group vs 37% (n = 38) in the oxytocin group (P = 0.050). Maternal and neonatal morbidity did not differ between balloon catheter and oxytocin groups: two uterine dehiscences vs one, one vs four maternal infections, five vs two hemorrhages and 11 vs five neonatal transfers, respectively. Heterogeneity of treatment effect for vaginal delivery was observed across initial Bishop scores. Balloon catheter was more effective for low values of bishop score. CONCLUSIONS: Balloon catheter tended to be associated with a higher probability of vaginal delivery as compared with low-dose intravenous oxytocin when used for induction of labor in women with a previous cesarean section and low Bishop score at induction.
