[Influence of water immersion on the use of epidural anesthesia during labor]. / Influence de l'immersion dans l'eau sur le recours à la péridurale pendant le travail.

OBJECTIVE: Immersion in water during labor could reduce pain and use of epidural anesthesia during childbirth. The main objective of this study was to evaluate the influence of immersion in water during labor on the use of epidural anesthesia in a midwife care setting. METHODS: We conducted a single-center retrospective study of all women who gave birth in the physiological ward of Saint-Étienne University Hospital between October 2020 and December 2022. RESULTS: The study did not find difference between immersion group and control group concerning the use of epidural anesthesia (P=0.49). The immersion group counted more women with a duration of labor greater than 6hours than in the control group. The multivariate analysis adjusted for parity and duration of labor did not find difference between both groups [OR 0.58; 95% CI (0.30; 1.09)]. CONCLUSION: Even if it does not seem to modify the use of epidurals, immersion in water does not seem to increase maternal and neonatal morbidity and mortality. It represents a therapeutic alternative with reasonable cost to offer for pregnant women who wish to give birth without epidural anesthesia.

Endometrial biopsy performed before the first in vitro fertilization does not impact the early pregnancy rate.

Endometrial biopsy (EB) has been showed to increase the rate of clinical pregnancy in patients who underwent in vitro fertilization (IVF) failures. The purpose of this work was to assess the impact of an EB performed before the first in IVF on the early pregnancy rate. Be One study is a prospective, single-centre, randomized, open-label study. In this parallel study, patients were evenly split into two groups. In one group, patients underwent an EB between days 17 and 22 of the menstrual cycle that precedes the ovarian stimulation. In the other group (control), no EB was performed. The hCG-positive rate (early pregnancy rate) was evaluated on day 14 after the ovarian puncture. In total, 157 patients were randomized in the EB group and 154 patients were in the control group. The early pregnancy rate was 33.1% (52/157) in the EB group and 29.9% (46/154) in the control group (p = 0.54). Other parameters, including perforation, endometritis, or pain level were reassuring. An EB performed during the luteal phase of the menstrual cycle preceding the stimulation of the first IVF did not increase early pregnancy rate.

EG-VEGF maternal levels predict spontaneous preterm birth in the second and third trimesters in pregnant women with risk factors for placenta-mediated complications.

Prediction of spontaneous preterm birth in asymptomatic women remains a great challenge for the public health system. The aim of the study was to determine the informational value of EG-VEGF circulating levels for prediction of spontaneous preterm birth in the second and third trimesters in pregnant women at high risk for placenta-mediated complications. A prospective multicenter cohort study including 200 pregnant patients with five-serum sampling per patient. Women with spontaneous preterm birth have higher concentrations of serum EG-VEGF than uncomplicated patients at 24 weeks, 28 weeks and 32 weeks (p = 0.03, 0.02 and < 0.001). The areas under the curve reached 0.9 with 100% sensitivity at 32 weeks for the prediction of spontaneous preterm birth. Serum EG-VEGF concentrations could be considered as a reliable biomarker of spontaneous preterm birth in high-risk for placenta-mediated complications pregnant women.

Robotic retroperitoneal para-aortic lymphadenectomy via single-site port.

Para-aortic staging is sometimes a standard feature in the management of pelvic cancers. Minimal invasive approach is recommended. Several routes are possible: extra-peritoneal or intraperitoneal depending on the expertise of the surgeon. We performed several extraperitoneal para-aortic lymphadenectomy using the Da Vinci Xi robotic system through single-site incision. We have developed a step-by-step guide from patient installation, installation of the Gelpoint V monotrocar, docking of the robot arms, to surgery, with the aim of performing the most efficient and safest procedure. The surgery does not differ from standard laparoscopic extraperitoneal lymphadenectomy. The advantages of minimally invasive robotic surgery in this indication are comparable to those of the standard laparoscopy approach. But through single-site incision, the Da Vinci Xi robot improves video quality, plus its wristed tools facilitates movements compared to conventional laparoscopy.

Mode of delivery after labor induction with vaginal dinoprostone versus oral misoprostol for women with unfavorable cervix at term.

OBJECTIVE: To compare the delivery mode after labor induction with 10 mg vaginal dinoprostone insert versus oral misoprostol 50 µg/4 h for women with an unfavorable cervix. MATERIAL AND METHODS: This is a retrospective observational study comparing the before/after introduction of oral misoprostol for labor induction, conducted at the Saint-Étienne University Hospital on a cohort of 396 women with a Bishop score <6. One hundred and twelve women (28.3%) were treated with a 10 mg vaginal dinoprostone insert versus 284 (71.7%) with oral misoprostol 50 µg/4 h. The primary outcome was the cesarean section rate. RESULTS: Labor induction with vaginal dinoprostone was independently associated with an increased rate of cesarean sections compared to oral misoprostol (aOR = 2.44; CI95% from 1.35 to 4.40; p = 0.003). The use of vaginal dinoprostone increased the induction rate during more than 48 h (18.8% versus 9.9%; p = 0.02), and the occurrence of fetal heart rate changes (34.8% versus 21.1%; p = 0.005). The maternofetal morbidity was similar. CONCLUSION: Labor induction with vaginal dinoprostone was independently associated with an increased rate of cesarean sections compared to oral misoprostol in women with an unfavorable cervix.

Classification Performance of the Ages and Stages Questionnaire: Influence of Maternal Education Level.

(1) Background: The Ages and Stages Questionnaire-Third Edition (ASQ-3) is a parental screening questionnaire increasingly being used to evaluate the development of preterm children. We aimed to assess the classification performance of the ASQ-3 in preterm infant follow-up. (2) Methods: In this cross-sectional study, we included 185 children from the SEVE longitudinal cohort born <33 weeks of gestational age between November 2011 and January 2018, who had both an ASQ-3 score at 24 months of corrected age (CA) and a revised Brunet-Lézine (RBL) scale score at 30 months of CA. The ASQ-3 overall score and sub-scores were compared to the RBL developmental quotient (DQ) scores domain by domain. The diagnostic performance of the ASQ-3 was evaluated with the RBL as the reference method by calculating sensitivity, specificity, and positive and negative likelihood ratios. A multivariate analysis assessed the association between low maternal education level and incorrect evaluation with the ASQ-3. (3) Results: The ASQ-3 overall score had a specificity of 91%, a sensitivity of 34%, a positive likelihood ratio of 3.82, and a negative likelihood ratio of 0.72. Low maternal education level was a major risk factor for incorrectly evaluating children with the ASQ-3 (odds ratio 4.16, 95% confidence interval 1.47-12.03; p < 0.01). (4) Conclusions: Regarding the low sensitivity and the impact of a low maternal education level on the classification performance of the ASQ-3, this parental questionnaire should not be used alone to follow the development of preterm children.

Serum D-dimer is not predictive of placenta-mediated complications in pregnancy at high risk: The multicentric prospective cohort AngioPred study.

Background: The theory that D-dimer level might has a predictive or diagnostic role in preeclampsia needs to be explored. Aim of the study was to evaluate the association between serum D-dimer level and the occurrence of placenta-mediated complications (PMC) in a pregnant population at high risk. Methods: A prospective multicenter cohort study including 200 pregnant women was conducted. Results: Serum D-dimer increases throughout pregnancy, with the highest levels at the end of gestation. Serum D-dimer level was similar for women with PMC and with no complication. Serum D-dimer level was not different in women with preeclampsia versus uncomplicated women. Serum D-dimer level was not different in women with early or late preeclampsia versus uncomplicated women. Conclusion: This result suggests that serum D-dimer level was not predictive of the PMC occurrence. This corroborates the fact that the origin of PMC based more on immunity than in hemostasis.

Impact of Enhanced Recovery After Surgery (ERAS) program in gynecologic oncology and patient satisfaction.

OBJECTIVE: The primary objective of this study was to compare lengths of stay since ERAS program implementation. We also evaluated ERAS protocol compliance, compared the outpatient rate, the complication rate and the readmission rate within 30 days after surgery and performed a satisfaction study. METHODS: This is a monocentric comparative study with a historical control group, performed in the gynecological surgery department of the University Hospital of Saint-Etienne. We compared a group of patients who underwent surgery in 2016, before the implementation of ERAS program, with a group of patients who underwent surgery from July 2021 to July 2022, for whom ERAS program was applied. RESULTS: 187 patients were included in this study, including 84 patients in the historical group before ERAS and 103 in the group with ERAS. Considering all approaches, the average length of stay decreased by 2 days (p<0.0001). Considering minimally invasive surgery, the outpatient rate increased from 5% to 50% (p<0.0001) and complication rate decreased from 23 to 11% (p = 0,04). The readmissions rate was similar. Satisfaction score for patients managed with ERAS program was 8.9/10. CONCLUSION: The implementation of ERAS program in gynecological oncology surgery allowed a reduction in length of stay, with a high outpatient rate, decreasing complications in case of minimally invasive surgery, without increasing the readmission rate, and was associated with good patient satisfaction.

Perinatal inflammation exposure and developmental outcomes 7 years after neonatal arterial ischaemic stroke.

AIM: To test the association between perinatal inflammation exposure and Full-Scale IQ (FSIQ) score 7 years after neonatal arterial ischaemic stroke (NAIS). METHOD: We conducted a cross-sectional ancillary study nested in a multicentric longitudinal French cohort of infants born at term with NAIS between November 2003 and October 2006. Seventy-three children were included (45 males, 28 females). The a priori defined primary outcome measure was the FSIQ score assessed with the Wechsler Intelligence Scale for Children, Fourth Edition at 7 years of age. RESULTS: Seventeen (23%) of the included children were exposed to perinatal inflammation. Exposure to perinatal inflammation was independently associated with an increase of FSIQ score (coefficient 13.4, 95% confidence interval 1.3-25.4; p = 0.03). Children exposed to perinatal inflammation had a higher median cerebral volume, a lower median lesion volume, and less extensive lesion distributions compared to non-exposed children. INTERPRETATION: We propose the existence of two NAIS categories: arteritis-associated NAIS in children exposed to perinatal inflammation and embolism-associated NAIS in children non-exposed to perinatal inflammation. Identifying these two NAIS categories would open the possibility for specific curative strategies: anti-inflammatory strategy in arteritis-associated NAIS and recanalization strategy in embolism-associated NAIS.

Uterine transarterial embolization as nonsurgical management for uterine rupture following vaginal delivery: A report of two cases.

Uterine rupture (UR) is an unexpected, rare, and serious obstetrical condition, occurring in less than 0.1% of pregnancies. Complete UR is defined as a direct communication between the uterine cavity and the peritoneum due to a complete rupture of the myometrium. Here, we present 2 cases of non-surgical management of UR following vaginal delivery, which were both treated by uterine transarterial embolization (UAE). A 26-year-old woman (G0P0) was referred to the emergency ward at 35 weeks of amenorrhea to treat the rupture of membranes, in the context of twin pregnancy. A vaginal delivery was performed and blood loss exceeded 2 liters. Gelatin sponge was injected in an attempt to occlude the right uterine artery. The injection was unsuccessful. After the medical team's discussion, it was decided to definitively occlude the right uterine artery. A 37-year-old woman (G3P3) was referred for a vaginal delivery for a medical termination at 38 weeks of amenorrhea. The ultrasound revealed a left latero-uterine pelvic hematoma, suggestive of UR. Four fibered coils were used to definitively occlude the left uterine artery. Computed tomography scan showed a progressive resorption of hematoma and satisfactory enhancement of the uterine wall in the 2 cases. Transarterial embolization may allow for bleeding to stop without resorting to exploratory laparotomy, with ad-integrum restitution of the uterine wall, and thus prevent a potential hysterectomy. The findings in these 2 cases suggest that UAE should be considered if pregnant women develop UR after delivery.

Fetal Movement Counting in Prolonged Pregnancies: The COMPTAMAF Prospective Randomized Trial.

In prolonged pregnancies, the risks of neonatal morbidity and mortality are increased. The aim of this trial was to assess the benefits of maternal information about fetal movement (FM) counting on neonatal outcomes in prolonged pregnancy. It was a prospective, single center, randomized, open-label study conducted from October 2019 to March 2022. Intention-to-treat analyses were performed on 278 patients randomized into two 1:1 groups (control group and FM counting group). The primary outcome was a composite score of neonatal morbidity (presence of two of the following items: fetal heart rate abnormality at delivery, Apgar score of <7 at 5 min, umbilical cord arterial pH of <7.20, and acute respiratory distress with mutation in neonatal intensive care unit). There was no significant difference between the two groups in the rate of neonatal morbidity (14.0% in the FM counting group versus 22.9% in the standard information group; p = 0.063; OR 0.55, 95% CI 0.29−1.0). In this study, fetal movement counting for women in prolonged pregnancy failed to demonstrate a significant reduction in adverse neonatal outcomes.

Pain and satisfaction in women induced by vaginal dinoprostone, double balloon catheter and oral misoprostol.

OBJECTIVE: The aim of this study was to evaluate the pain experience of women induced by intravaginal dinoprostone (Propess®), oral misoprostol (Angusta®) or double balloon catheter (Cook®). METHODS: This single-center prospective study was carried out in the obstetric gynecology department of the university hospital of Saint-Etienne from March 2018 to April 2021 in women requiring cervical ripening for the purpose of artificial labor induction. RESULTS: We included 82 women in the oral misoprostol group, 35 in the vaginal dinoprostone group and 58 in the balloon group. The overall pain, assessed by a numerical scale from 0 to 10, was similar for the different methods of induction (p = 0.253). Pain at insertion was greater with the double balloon catheter compared to the vaginal dinoprostone (3.67 versus 5.75 p = 0.001). Pain in the 2 h prior to the delivery room was greater with vaginal dinoprostone and oral misoprostol compared with the double balloon catheter (7.91 and 7.4 versus 5.47 respectively, p = <0.0001). Women induced by balloon catheter would more often have preferred to be induced by another method compared to those induced by oral misoprostol or vaginal dinoprostone (p = 0.004). Adjusting for previous cesarian section, gestational age at delivery, need for oxytocin augmentation and indication for induction, women induced by balloon were five times more risk to prefer another induction method (OR 5.01 95% CI [1.09-23.03], p = 0.038). There was no significant difference in stress and overall experience of induction depending on the method. CONCLUSION: In order to improve the women experience, information, consent and participation in the decisions and choices of their induction method are essential.

Midwives' attitudes toward participation of pregnant individuals in a preventive vaccine hypothetical clinical trial.

INTRODUCTION: Pregnant individuals are frequently excluded from clinical trials. Yet, inclusion of Pregnant individuals is of interest in vaccinology including during health crisis. Promotion of clinical trials by midwives may facilitate the decision making of Pregnant individuals. Attitudes of midwives about pregnant individuals participation in a vaccine clinical trial have been little explored. METHODS: We conducted an anonymous survey from the 11th of September to the 11th of November 2020. Primary endpoint was the willingness to encourage Pregnant individuals to participate in a hypothetical respiratory syncytial virus (RSV) vaccine clinical trial. RESULTS: Among 398 midwives who answered the questionnaire, 113 (28.3 %) were likely to encourage Pregnant individuals to participate in the vaccine clinical trial, this proportion ranged from 25 % in senior midwives to 34.5 % among the students. After adjustment on age, parenthood, previous personal attitudes of vaccine hesitancy, and psychological antecedents of vaccinations (5C-model), the only predictor of the promotion of the clinical trial was the experience of vaccine education (evaluated by a 20-point score) with an adjusted odds ratio of 1.09 (1.01-1.18, p = 0.027) for a one-point increase. Vaccine hesitancy and psychological antecedents of vaccinations were not associated with a lower promotion of pregnant individuals trial participation by midwives. CONCLUSION: Few respondents were likely to encourage Pregnant individuals to participate in a vaccine clinical trial. Midwives who considered themselves to have a good training about vaccines were more prone to encourage Pregnant individuals to participate in a RSV vaccine clinical trial.

Venous Thromboembolism Risk Score and Pregnancy.

Venous thromboembolism (VTE) is a major contributor to maternal morbidity and mortality worldwide. Pregnancy is associated with the development of a baseline hypercoagulable state. The two strongest risk factors for pregnancy-associated VTE are previous VTE and/or high risk thrombophilia. The others risk factors for VTE during pregnancy are well known such as maternal, pregnancy and delivery characteristics. Considering the variation in recommendation in guidelines and low-quality evidence on the prevention, diagnosis and treatment, practice differs between countries and clinical institutions. Some authors developed risk scores, enabling individualized estimation of thrombotic risk during pregnancy, and permitting implementation of a risk-adapted strategy for thromboprophylaxis during pregnancy and postpartum. This review describes the existing VTE risk scores during the antenatal and postnatal period. The important message beyond the score used is that all women should undergo VTE risk factor assessment. The use of a Computerized Clinical Decision Support System for VTE risk assessment should be explored in obstetrics.

Animal Models of Chorioamnionitis: Considerations for Translational Medicine.

Preterm birth is defined as any birth occurring before 37 completed weeks of gestation by the World Health Organization. Preterm birth is responsible for perinatal mortality and long-term neurological morbidity. Acute chorioamnionitis is observed in 70% of premature labor and is associated with a heavy burden of multiorgan morbidities in the offspring. Unfortunately, chorioamnionitis is still missing effective biomarkers and early placento- as well as feto-protective and curative treatments. This review summarizes recent advances in the understanding of the underlying mechanisms of chorioamnionitis and subsequent impacts on the pregnancy outcome, both during and beyond gestation. This review also describes relevant and current animal models of chorioamnionitis used to decipher associated mechanisms and develop much needed therapies. Improved knowledge of the pathophysiological mechanisms underpinning chorioamnionitis based on preclinical models is a mandatory step to identify early in utero diagnostic biomarkers and design novel anti-inflammatory interventions to improve both maternal and fetal outcomes.

Preeclampsia and Venous Thromboembolism: Pathophysiology and Potential Therapy.

Preeclampsia (PET) is a multisystem inflammatory disorder that represents a leading cause of feto-maternal morbidity and mortality, complicating 2-5% of all pregnancies. PET incurs an increased risk of venous thromboembolism, which is one of the leading causes of death in pregnancy and in the postpartum period. This prothrombotic phenotype is attributable to the maternal phase of PET, which is characterized by a systemic inflammatory response and coagulation activation. Research continues to be undertaken in terms of preventative measures, however, currently revolves around pharmacological low dose aspirin initiated in the first trimester of pregnancy for those with risk factors. Treatment involves antenatal corticosteroids for fetal lung development in preterm birth, parenteral magnesium sulfate for fetal neuroprotection and maternal seizure prophylaxis, and timely birth of the fetus and placenta being the only definitive treatment of PET. Patients with a venous thromboembolism (VTE) risk deemed to be >1-3% are treated with pharmacological thromboprophylaxis in the form of low molecular weight heparin. Completing each woman's VTE risk assessment is crucial, particularly in the setting of PET, as there is also a proven associated competing hemorrhagic risk.

Role of NLRP7 in Normal and Malignant Trophoblast Cells.

Gestational choriocarcinoma (CC) is an aggressive cancer that develops upon the occurrence of abnormal pregnancies such as Hydatidiform moles (HMs) or upon non-molar pregnancies. CC cells often metastasize in multiple organs and can cause maternal death. Recent studies have established an association between recurrent HMs and mutations in the Nlrp7 gene. NLRP7 is a member of a new family of proteins that contributes to innate immune processes. Depending on its level of expression, NLRP7 can function in an inflammasome-dependent or independent pathway. To date, the role of NLRP7 in normal and in malignant human placentation remains to be elucidated. We have recently demonstrated that NLRP7 is overexpressed in CC trophoblast cells and may contribute to their acquisition of immune tolerance via the regulation of key immune tolerance-associated factors, namely HLA family, ßCG and PD-L1. We have also demonstrated that NLRP7 increases trophoblast proliferation and decreases their differentiation, both in normal and tumor conditions. Actual findings suggest that NLRP7 expression may ensure a strong tolerance of the trophoblast by the maternal immune system during normal pregnancy and may directly affect the behavior and aggressiveness of malignant trophoblast cells. The proposed review summarizes recent advances in the understanding of the significance of NLRP7 overexpression in CC and discusses its multifaceted roles, including its function in an inflammasome-dependent or independent pathways.
