Qualitative analysis of mothers' perception related to the delivery of information regarding preterm births.

BACKGROUND: Preterm birth is a major health issue due to its potential outcomes and socioeconomic impact. Prenatal counseling is of major importance for parents because it is believed that the risk of preterm birth is associated with a higher parental mental burden. Nowadays in France, the content and delivery of antenatal counseling is based on personal experience since there is a lack of official guidelines. The goal of the study was to evaluate maternal perception of antenatal information delivered in the setting of preterm births. METHODS: A qualitative study was performed using semi-structured individual interviews of 15 mothers with a child born > 26-34 GW. Data analysis was based on a constant comparative method. RESULTS: Concerning prenatal counseling content, parents wanted to be informed of their role in the care of their preterm child more so than statistics that were not always considered relevant. Parents' reactions to the announcement of the risk of a preterm birth was dominated by stupefaction, uncertainty and anxiety. When it comes to the setting of prenatal counseling, patients' room was deemed an appropriate setting by parents and ideally the presence of a coparent was appreciated as it increased patients' understanding. The physicians' attitude during the counseling was considered appropriate and described as empathic and optimistic. The importance of support throughout the hospitalization in the form of other parents' experiences, healthcare professionals and the possibility to preemptively visit the NICU was emphasized by participants. Delivery experience was dominated by a sense of uncertainty, and urgency. Some leads for improvement included additional support of information such as virtual NICU visit; participants also insisted on continuity of care and the multidisciplinary aspect of counseling (obstetrician, neonatologist, midwife, nurse, lactation consultant and psychologist). CONCLUSION: Highlighting parents' expectations about prenatal counseling could lead to the establishment of overall general guidelines. However, some topics like the use of statistics and mentioning the risk of death underline the importance of a personalized information.

Retrospective evaluation of labor induction with scar uterus at the university hospital of Rennes.

OBJECTIVE: The aim of the study was a retrospective evaluation of labor induction in women with one previous cesarean section. The primary outcome was the mode of delivery. We also studied the severe maternal and neonatal morbidity and identify some prediction factors of vaginal delivery after labor induction after one previous cesarean section. STUDY DESIGN: This was a retrospective observational monocentric study performed over the period from January 1st, 2016 to April 30th, 2020 at the university hospital of Rennes. Were included women with scar uterus because of one previous cesarean section with a viable singleton fetus in cephalic presentation and an induction of labor for medical reason, at term. Multivariate logistic regression analysis was used to analyze prediction of vaginal delivery after labor induction after one previous cesarean section. We also studied maternal (included uterine rupture, loss of blood, obstetrical injury of anus sphincter) and neonatal (APGAR score, arterial umbilical pH after 1 minute of life and eventual admission to neonatal unit) morbidity. We used a stepwise multivariate logistic regression model to select variables for multivariate analysis. The model with the lowest Akaike Index Criteria was chosen. RESULTS: The study enrolled 353 women with scar uterus: 121 women were induced by balloon catheter, 57 by osmotic cervical dilatators, 91 by oxytocin alone, 84 by amniotomy. Vaginal delivery rate was 47,9%. There was 45% of vaginal delivery in the group with Bishop < 6 before induction of labor versus 62% in the group with Bishop ≥ 6. There was no statistically significative difference in neonatal and maternal severe morbidities between vaginal delivery and cesarean section: 4,5% of severe maternal morbidities (n = 16). Among their, we highlighted 7 uterine ruptures (3,8%). We observed also 3% of postpartum severe hemorrhage in vaginal delivery group (n = 5) against 1,6% in cesarian section group (n = 3) with no statistical significant difference (p = 0,632). Regarding to the obstetric perineal tears and lacerations we noticed 1,2% of OASIS 3 (n = 2) and 0,6% of OASIS 4 (n = 1). Severe neonatal morbidities were comparable by mode of delivery without significant difference: APGAR score at 5 min was similar (p = 1), as well as arterial umbilical pH after 1 min. (p = 0.719) and admissions to a neonatal unit (p = 1). Two variables were statistically associated with vaginal delivery after labor induction in women with scar uterus: Bishop score ≥ 6 (OR = 0,44; 95%CI: 0,25-0,81) and/or previous vaginal delivery after cesarean section (OR = 0,17; 95%CI: 0,08-0,35). CONCLUSION: With 47,9% of vaginal delivery after labor induction in women with scar uterus, only 3.8% (n = 7/353) of uterine ruptures, less than 1% APGAR < 7 at 5 min (n = 3/353), induction on scar uterus should be consider in obstetrical practice. Bishop score ≥ 6 and/or previous vaginal delivery after cesarean section are associated to vaginal delivery after labor induction.

Trial of labor versus elective cesarean delivery for patients with two prior cesarean-sections: A retrospective propensity score analysis.

INTRODUCTION: Despite awareness of obstetricians to the constant increase in the number of cesarean sections in recent years, the fear of a uterine scar rupture is still present and influences the choice of the mode of delivery in patients with two previous cesarean sections. However, several clinical studies have suggested that, under certain conditions, vaginal birth after two cesarean sections is usually successful and safe. OBJECTIVE: The objective of this study was to compare maternal and neonatal issues according to the planned mode of delivery in patients with two previous cesarean sections. METHODS: It was a retrospective observational comparative study at Rennes University Hospital between January 1, 2013, and December 31, 2020. We performed a propensity score for the comparison of neonatal outcomes: cord pH, cord lactates, Apgar scores, transfer to neonatal unit and deaths, according to the planned delivery mode. Secondary outcomes were maternal issues: uterine rupture, post-partum hemorrhage, deaths. RESULTS: A total of 410 patients with two previous cesarean section were eligible for our study. Prophylactic cesarean was performed in 358 cases (87.3%). Trial of labor was attempted in the 52 remaining patients (12.7%), 67.3 % of whom were successful. Neonatal weight, APGAR score at 1-5-10 min, and pH on cord blood were comparable in both groups. One case of uterine rupture occurred in the trial of labor group. CONCLUSION: Trial of labor seems to be a reasonable option for women with two previous cesarean sections in a selected population.

Maternal occupational exposure to organic solvents and intrauterine growth in the ELFE cohort.

BACKGROUND: In developed countries, about 15% of women are occupationally exposed to solvents. Associations between this maternal occupational exposure and intrauterine fetal growth are inconsistent, but almost no existing study has investigated this relation by solvent family (oxygenated, petroleum, and chlorinated), although they may affect fetal growth differently. OBJECTIVES: To investigate the relations between maternal occupational solvent exposure, by solvent family, and the risk of neonates born small for gestational age (SGA), or with low birthweight, or with small head circumference (HC). METHODS: Among the 18,040 women enrolled in the Elfe rather than included in the Elfe birth cohort, we included 13,026 women who worked during pregnancy (72% of the cohort). Information about maternal occupations and industrial activities during pregnancy was collected by questionnaire at the maternity ward, and completed at 2-month when necessary. Using Matgéné job-exposure matrices, we assessed maternal occupational exposure to solvents. Logistic and multiple linear regressions were used to assess the association between maternal occupational solvent exposure and SGA status, birth weight, and HC. Analyses were conducted for exposure during pregnancy and also stratified by the trimester that pregnancy leave began. RESULTS: We observed a higher risk of SGA newborns among mothers occupationally exposed during pregnancy to petroleum solvents (ORadjusted = 1.26; 95%CI: 1.01 to 1.57). Among women working until the third trimester of pregnancy, we observed a higher risk of SGA newborns to those occupationally exposed to oxygenated solvents (ORadjusted = 1.75; 95%CI: 1.11 to 2.75), a significantly lower birthweight for infants of mothers exposed to petroleum solvents (ßadjusted = -47.37 g; -89.33 to -5.42), and a lower HC among newborns of those occupationally exposed to oxygenated solvents (ßadjusted = -0.28; -0.49 to -0.07) and to chlorinated solvents (ßadjusted = -0.29; -0.53 to -0.05). DISCUSSION: Our results suggest that maternal occupational solvent exposure may influence fetal growth, especially exposure into the third trimester of pregnancy.

Predictive value of head-perineum distance measured at the initiation of the active second stage of labor on the mode of delivery: A prospective cohort study.

OBJECTIVE: The objective was to assess the predictive value of head-perineum distance measured at the initiation of the active second stage of labor on the mode of delivery. MATERIAL AND METHODS: It was a prospective cohort study in an academic Hospital of Rennes, France, from July 1, 2020 to April 4, 2021 including 286 full-term parturients who gave birth to a newborn in cephalic presentation. A double-blind ultrasound measurement of the head-perineum distance was performed during the second phase of labor within five minutes after the onset of pushing efforts. The primary outcome was the mode of delivery (spontaneous vaginal delivery versus instrumental vaginal delivery or cesarean section). We performed a multivariate analysis to determine the predictive value of the head-perineum distance by adjusting on potential confounders. RESULTS: Overall, 199 patients delivered by spontaneous vaginal delivery, 80 by instrumental vaginal delivery, and seven by cesarean section. The head-perineum distance measured at the beginning of pushing efforts was predictive of the mode of delivery with a threshold at 44 mm (crude: sensitivity = 56.8 % and specificity = 79.3 %; adjusted: sensitivity = 79.4 % and specificity = 87.4 %). The risk of medical intervention was higher when the head-perineum distance is>44 mm with an adjusted OR of 2.78 [1.38; 5.76]. CONCLUSION: The head-perineum distance measured at the initiation of the active second stage of labor is predictive of the mode of delivery. Head-perineum distance below 44 mm predicts a vaginal delivery with the best diagnostic performance, and optimizes the time to start pushing efforts.

Prenatal exposure to pesticides and risk of preeclampsia among pregnant women: Results from the ELFE cohort.

BACKGROUND: Preeclampsia is a pregnancy-specific syndrome caused by abnormal placentation. Although environmental chemicals, including some pesticides, are suspected of impairing placentation and promoting preeclampsia, its relationship with preeclampsia has been insufficiently explored. OBJECTIVES: We aimed to investigate the relation between non-occupational exposure to pesticides during pregnancy and the risk of preeclampsia. METHODS: The study cohort comprised 195 women with and 17,181 without preeclampsia from the ELFE birth cohort. We used toxicogenomic approaches to select 41 pesticides of interest for their possible influence on preeclampsia. We assessed household pesticide use (self-reported data), environmental exposure to agricultural pesticides (geographic information systems), and dietary exposure (food-frequency questionnaire with data from monitoring pesticide residues in food and water). Dietary exposures to pesticides were grouped into clusters of similar exposures to resolve collinearity issues. For each exposure source, pesticides were mutually adjusted, and odds ratios estimated with logistic regression models. RESULTS: The quantity of prochloraz applied within a kilometer of the women's homes was higher in women with than without preeclampsia (fourth quartile vs. others; adjusted odds ratio [aOR] = 1.54; 95%CI: 1.02, 2.35), especially when preeclampsia was diagnosed before 34 weeks of gestation (aOR = 2.25; 95%CI: 1.01, 5.06). The reverse was observed with nearby cypermethrin application (aOR = 0.59, 95%CI: 0.36, 0.96). In sensitivity analyses, women with preeclampsia receiving antihypertensive treatment had a significantly higher probability of using herbicides at home during pregnancy than women without preeclampsia (aOR = 2.20; 95%CI: 1.23, 3.93). No statistically significant association was found between dietary exposure to pesticide residues and preeclampsia. DISCUSSION: While the most of the associations examined remained statistically non-significant, our results suggest the possible influence on preeclampsia of residential exposures to prochloraz and some herbicides. These estimations are supported by toxicological and mechanistic data.

Performance of diagnostic ultrasound to identify causes of hydramnios.

INTRODUCTION: We aimed to assess the diagnostic yield of ultrasonography in the identification of the etiology of hydramnios, and the added value of MRI or amniocentesis. METHODS: We conducted a single-center retrospective study including pregnancies with confirmed hydramnios (defined as deepest pocket ≥8 cm) between January 2013 and May 2017. Twin pregnancies, secondary hydramnios discovered after the diagnosis of a causal pathology, and pregnancies of unknown outcome were excluded. All pregnancies underwent a targeted scan, and selected cases underwent MRI or amniocentesis. RESULTS: A total of 158 patients with confirmed hydramnios were included. Hydramnios was associated with a fetal pathology in 37 cases (23.4%), with diabetes in 39 (24.6%), isolated macrosomia in 16 (10.1%), and considered idiopathic in 66 (41.7%). Ultrasonography established a diagnosis of the underlying pathology in 73% of cases. Amniocentesis was done in 31 cases (20%) and it allowed diagnosis of chromosome anomalies, esophageal atresia, myotonic dystrophy congenital type, Prader-Willi syndrome, and Bartter syndrome. MRI was done in 15 cases (10%) and it allowed one additional diagnosis of esophageal atresia. The diagnostic yields of MRI and amniocentesis were 91.7% and 95.2%, respectively. There were five false positive diagnoses at ultrasonography, and one false positive diagnosis at MRI. CONCLUSION: Hydramnios can be associated with a wide variety of underlying pathologies. Diagnostic ultrasound can attain a diagnosis in the majority of cases. Amniocentesis offers a valuable complementary assessment.

Surgical management of isthmocele symptom relief and fertility.

OBJECTIVE: To describe symptoms and fertility and quality of life outcomes after isthmocele surgery. STUDY DESIGN: We conducted a retrospective study on from January 2012 to December 2017 in two tertiary referral centers in Rennes (France). All the patients diagnosed with isthmocele and operated were included. They all underwent isthmocele surgery by hysteroscopy, vaginal way or laparotomy. RESULTS: The following data were collected: surgical procedure, symptoms and fertility before and after surgery, patient satisfaction about the surgery, and quality of life after surgery. Eighteen patients were included. The mean duration of follow-up was 15 months. Surgical procedures consisted of hysteroscopy (n = 5/18, 27.8%), vaginal surgery (n = 8/18, 44.4%) and laparotomy (n = 5/18, 27.8%). Surgical indications were: secondary infertility (n = 10/18, 55 %), pelvic pain (n = 5/18, 28%) and abnormal uterine bleeding (n = 3/18, 17%). Among patients with abnormal uterine bleeding, improvement was obtained after hysteroscopy, laparotomy and vaginal surgery for 83.3%, 75% and 50%, respectively. Among those with pelvic pain, improvement was obtained after hysteroscopy, laparotomy and vaginal surgery for 80%, 81% and 66%, respectively. One patient (1/18, 5.5%) had post-operative complication. Of the 12 patients who wished to conceive eleven pregnancies were obtained (91.7%). Of the 10 patients with secondary infertility, six became pregnant (60%). Five pregnancies (5/11, 45.4%) were carried to full term, including four in patients whose surgical indication was infertility. Among these, one patient had a vaginal delivery (after vaginal surgery) without obstetric complication. All patients operated on by hysteroscopy would recommend this surgery versus 75% of patients with vaginal surgery and 60% of patients with laparotomy (p = 0.24). Pain and quality-of-life scores were comparable between the three groups. CONCLUSION: Isthmocele surgery is effective for abnormal uterine bleeding, pain and infertility regardless of the surgical route.

Performance of a quick pregnancy test on whole blood in early pregnancy units: a prospective cohort study.

OBJECTIVE: To assess the diagnostic performance of the NG-Test human chorionic gonadotropin (hCG) WB, which is a new point-of-care (POC) hCG whole-blood test. MATERIALS AND METHODS: This prospective study included women consulted in early pregnancy units for vaginal bleeding and/or pelvic pain with unknown pregnancy status after medical consultation including a pelvic ultrasound scan. A new POC test (the NG-Test hCG WB) and the usual laboratory serum test (considered the gold standard) were performed in patients. The results were interpreted in a blinded manner. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated for the NG-Test hCG WB. RESULTS: During the study period, 200 patients were included. The pregnancy rate was 17%. For the laboratory test, with a 5 UI/l hCG positivity threshold, the sensitivity, specificity, PPV, NPV, and Youden index of the NG-Test hCG WB were 89.7, 100, 100, 97.9, and 0.90%, respectively. Considering a 10 UI/l hCG positivity threshold, test sensitivity, specificity, PPV, NPV, and Youden index were 96.3, 100, 100, 99.3, and 0.96%, respectively. False-negative cases were either extremely brief pregnancies or residual hCG after miscarriage. The result was obtained within 5 min with the NG-Test hCG WB versus 90±31 min with the laboratory test. It was easy to use. CONCLUSION: The NG-Test hCG WB showed a high sensitivity, specificity, PPV, and NPV. Its use as triage in the case of a negative pelvic ultrasound exam is a potential strategy to improve patient flow, with an average time saving of 85 min.

Comparison of adjustable continence therapy periurethral balloons and artificial urinary sphincter in female patients with stress urinary incontinence due to intrinsic sphincter deficiency.

INTRODUCTION AND HYPOTHESIS: The objective was to compare the outcomes of the ACT® device with those of the artificial urinary sphincter (AUS) AMS 800 in the treatment of stress urinary incontinence (SUI) due to sphincter deficiency in women. METHODS: All the women who underwent surgical treatment for SUI due to intrinsic sphincter deficiency from 2007 to 2017 were included in a single-center retrospective study. The primary endpoint was the functional outcome. Perioperative functional parameters of the two groups were compared. RESULTS: Twenty-five patients underwent an ACT® implantation and 36 an AUS implantation. Patients in the AUS group were younger (62.9 vs 70.4 years; p = 0.03) with less comorbidity (ASA Score = 3 in 12.1% vs 33.3%; p = 0.005). Operative time and hospital stay were shorter in the ACT® group (45.7 vs 206.1 min; p < 0.001; 1.7 vs 7 days; p < 0.001 respectively). There was a higher rate of intraoperative complications in the AUS group (47% vs 8%; p < 0.001) but the rates of postoperative complications were similar between both groups. The ACT® was associated with an increased risk of urinary retention (20% vs 2.8%; p = 0.04). Results were in favor of AUS for: decrease in USP stress incontinence subscore (-7.6 vs -3.2; p < 0.001), number of pads per 24 h (- 4.6 vs -2.3; p = 0.002), PGII scale (PGII = 1: 61.1% vs 12%; p < 0.001), and cure rate (71.4% vs 21.7%; p < 0.001). CONCLUSIONS: In the present series, keeping in mind the significantly different baseline characteristics, AUS implantation was associated with better functional outcomes than the ACT® in female patients with SUI due to intrinsic sphincter deficiency, but with a higher intraoperative complications rate, longer operative time, and a longer stay.
