[Evolution of the obstetrical Shock Index in postpartum haemorrhage according to the use of sulprostone]. / Évolution du Shock Index obstétrical lors d'une hémorragie du post-partum selon le recours à la sulprostone.

OBJECTIVES: The Shock Index (SI) is used in emergency medicine to assess the severity of active bleeding and in the postpartum context for postpartum haemorrhage (PPH). We investigated the diagnostic value of haemodynamic parameters (SI, heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP)) in predicting subsequent use of uterotonic sulprostone treatment. METHODS: This was a retrospective study including parturients with PPH ≥ 500mL between January 2017 and December 2018. Hemodynamic parameters at the diagnosis of PPH were compared according to whether the patient required subsequent sulprostone treatment (sulprostone(+) group) or not (sulprostone(-) group). RESULTS: We included in the analysis 147 patients. The SI was significantly higher in the sulprostone(+) group (0.92±0.28 vs. 0.83±0.22; p=0.04). The SBP (107.2±17.5 vs. 113.8±17.7mmHg; p=0.03), DBP (56.8±12,2 vs. 61.5±13,2mmHg; p=0.04), MAP (73.6±12.6 vs. 78.5±13.4mmHg; p=0.03) were significantly lower in the same group. No difference between AUC of these parameters to predict the use of sulprostone was found (AUC between 0.59 and 0.61). No significant difference was found for the HR between the two groups. CONCLUSION: The diagnostic value of SI appeared to be low and similar to other haemodynamic parameters in predicting the use of sulprostone.

Clinical practice recommendations for nurse-administered intramuscular injections in mental health: A modified Delphi study.

AIM: To develop clinical practice recommendations for nurse-administered intramuscular injections in mental health. BACKGROUND: Intramuscular injection is the main route of long-acting injectable antipsychotics' administration that appear to improve the long-term prognosis of mental illness. Specific guidelines related to the nurse administration of intramuscular injections need to be updated and to explore not only the technical aspects of this procedure. DESIGN: A modified RAND/University of California Los Angeles (UCLA) appropriateness method Delphi study was conducted between October 2019 and September 2020. METHODS: A multidisciplinary steering committee conducted a literature review and developed a list of 96 recommendations. These recommendations were submitted in a two-round Delphi electronic survey to a panel of 49 experienced practicing nurses from five mental health hospitals in France. Each recommendation was rated for its appropriateness and applicability in clinical practice on a 9-point Likert scale. Consensus among nurses was evaluated. The steering committee discussed the results after each round and approved the final set of recommendations. RESULTS: A final set of 79 specific recommendations were accepted for their appropriateness and applicability in clinical practice. Recommendations were classified in five domains: legal and quality assurance aspects, nurse-patient relationship, hygiene, pharmacology, and injection technique. CONCLUSION: The established recommendations placed patients at the heart of the decisions concerning the intramuscular injection and underlined the need for specific training programs. Future research should focus on the integration of these recommendations in clinical practice, by both before-and-after studies and regular assessments of professional practices with relevant indicators. IMPACT: The recommendations developed for good nursing practices explored not only the technical aspects but integrated the nurse-patient relationship. These recommendations may impact usual practices of administration of long-acting injectable antipsychotics and most of them could be applied in many countries. NO PATIENT OR PUBLIC CONTRIBUTION: Due to the study design.

Change in Hemoglobin Was Not a Reliable Diagnostic Screening Test for Postpartum Hemorrhage: A French Prospective Multicenter Cohort Study (HERA Study).

Changes between pre- and postpartum hemoglobin might be useful for optimizing the postpartum diagnosis of postpartum hemorrhage (PPH), defined as a blood loss exceeding 500 mL. This study's principal objective was to estimate the mean change in hemoglobin (between pre/post-delivery hemoglobin) among women with vaginal deliveries and PPH. The secondary objectives were to analyze: hemoglobin changes according to blood volume loss, the appropriateness of standard thresholds for assessing hemoglobin loss, and the intrinsic and extrinsic performances of these threshold values for identifying PPH. French maternity units (n = 182) participated in the prospective HERA cohort study. Women with a vaginal delivery at or after a gestation of 22 weeks with a PPH (n = 2964) were eligible. The principal outcome was hemoglobin loss in g/L. The mean hemoglobin change was 30 ± 14 g/L among women with a PPH. Overall, hemoglobin decreased by at least 10% in 90.4% of women with PPH. Decreases ≥ 20 g/L and ≥40 g/L were found, respectively, in 73.9% and 23.7% of cases. Sensitivity and specificity values for identifying PPH were always <65%, the positive predictive values were between 35% and 94%, and the negative predictive values were between 14% and 84%. Hemoglobin decrease from before to after delivery should not be used as a PPH diagnostic screening test for PPH diagnosis for all vaginal deliveries.

Opti'care protocol: a randomised control trial to evaluate the impact of a mobile antenatal care clinic in isolated rural areas on prenatal follow-up.

INTRODUCTION: Rural residence appears to be a factor of vulnerability among pregnant women with poor clinical antenatal care. Our principal objective is to assess the impact of an infrastructure for a mobile antenatal care clinic on the completion of antenatal care for women identified as geographically vulnerable in a perinatal network. METHODS AND ANALYSIS: Controlled cluster-randomised study in two parallel arms comparing an intervention group with an open-label control group. This study will concern the population of pregnant women who must live in one of the municipalities covered by the perinatal network and considered to be an area of geographic vulnerability. The cluster randomisation will take place according to the municipality of residence. The intervention will be the implementation of pregnancy monitoring by a mobile antenatal care clinic. The completion of antenatal care between the intervention and control groups will be a binary criterion: 1 will be attributed to each antenatal care that includes all visits and supplementary examinations. Sample size has been estimated to be 330 at least with an 80% participation rate.The univariate analyses will compare the follow-up rates (with Fisher's exact test), and all individual characteristics collected (Fisher's exact test, Student's t-test) between the two groups. The multivariate analysis will use a mixed linear model analysis and consider the cluster effect as random; the initial model will include known confounders from the literature, confounders identified in univariate analyses, and the clinically relevant prognostic factors. All of these factors will be taken into account in the model as a fixed effect. ETHICS AND DISSEMINATION: The Patient Protection Committee North-West II approved this study on 4 February 2021 (IRB 2020-A02247-32). The results will be the subject of scientific communications and publications. TRIAL REGISTRATION NUMBER: NCT04823104.

Does the type of pushing at delivery influence pelvic floor function at 2 months postpartum? A pragmatic randomized trial-The EOLE study.

INTRODUCTION: Maternal pushing techniques during the second stage of labor may affect women's pelvic floor function. Our main objective was to assess the impact of the type of pushing used at delivery on the mother's medium-term pelvic floor function. MATERIAL AND METHODS: This is a secondary analysis of a randomized clinical trial (clinicaltrials.gov: NCT02474745) that took place in four French hospitals from 2015 through 2017 (n = 250). Women in labor with a singleton fetus in cephalic presentation at term who had undergone standardized training in both of these types of pushing were randomized after cervical dilation ≥7 cm. The exclusion criteria were a previous cesarean, a cesarean delivery in this pregnancy or a fetal heart rate anomaly. In the intervention group, open-glottis (OG) pushing was defined as a prolonged exhalation contracting the abdominal muscles to help move the fetus down the birth canal. Closed-glottis (CG) pushing was defined as Valsalva pushing. The principal outcome was the stage of pelvic organ prolapse (POP) assessed by the Pelvic Organ Prolapse-Quantification 2 months after delivery. A secondary outcome was incidence of urinary incontinence (UI). The results of our multivariable, modified intention-to-treat analysis are reported as crude relative risks (RRs) with their 95% confidence intervals. RESULTS: Our analysis included 207 women. Mode of birth was similar in both groups. The two groups did not differ for stage II POP: 10 of 104 (9.4%) in the OG group compared with 7 of 98 (7.1%) in the CG group, for a RR 1.32, 95% confidence interval [CI] 0.52-3.33, and an adjusted RR of 1.22, 95% CI 0.42-3.6. Similarly, the incidence of UI did not differ: 26.7% in the OG group and 28.6% in the CG group (aRR 0.81, 95% CI 0.42-1.53). Subgroup analysis suggests that for secundiparous and multiparous women, OG pushing could have a protective effect on the occurrence of UI (RR 0.33, 95% CI 0.13-0.80). CONCLUSIONS: The type of directed pushing used at delivery did not impact the occurrence of pelvic organ prolapse 2 months after delivery. OG pushing may have a protective effect against UI among secundiparous and multiparous women.

Prediction of Iron Deficiency Anemia in Third Trimester of Pregnancy Based on Data in the First Trimester: A Prospective Cohort Study in a High-Income Country.

Background: Systematic iron supplementation may be harmful in pregnant women with non-depleted iron. Our objectives were to estimate the prevalence of anemia at the third trimester of pregnancy (T3) and to identify the parameters at the first trimester (T1), which best predict anemia at T3. Methods: This prospective cohort study in France included pregnant women at T1 without non-iron deficiency anemia. Clinical and social characteristics, health-related quality of life, blood count, and a frozen blood sample were collected at T1 and/or T3. Secondly, a matched nested case−control study was built for women with anemia at T3 but not at T1. Multivariate analyses and ROC curves were used to identify the best predictive parameter(s) of anemia at T3. Results: The prevalence of anemia at T3 in the cohort (629 women) was 21.9% (95% CI 18.7−25.2%). In the matched nested case−control study (256 women), hemoglobin (Hb), serum ferritin (SF) and the SF/soluble transferrin receptor ratio at T1 were predictive of anemia at T3 (p < 0.001); however, clinical and social characteristics, as serum hepcidin were not. In multivariate analyses, Hb at T1 was the best predictive biomarker of anemia at T3 with a cut-off value of 120 g/L (specificity 87.5%). Conclusions: The prevalence of anemia at the end of pregnancy remained high in a High-Income Country. Clinical, social, and biochemical parameters did not seem useful to predict anemia at T3 and could not guide iron supplementation. We suggest systematically performing a simple blood count in the first trimester of pregnancy and offering oral iron supplementation for women with Hb < 120 g/L.

Workplace Lactation Support: A Cross-Sectional Study in a University Hospital and a Perinatal Network.

Return to work negatively affects the initiation and duration of breastfeeding. Our study's objective was to assess the percentage of departments in Auvergne with an appropriate space for pumping milk at work. Our cross-sectional survey investigated the arrangements for facilitating the continuation of breastfeeding on return to work at all departments at the Clermont-Ferrand University Hospital Center and perinatal (obstetric and pediatric) departments in this region. Our principal endpoint was the percentage of departments reporting that they had a lactation room­a room where nursing mothers can express milk­and whether it met the criteria defined by the French Labor Code. Among 98 respondents, 44 departments (44.9%) did not offer lactation rooms; of the remaining 54 departments, only 11 rooms met the legal requirements. All perinatal departments offered lactation rooms. The availability of a lactation room was associated with other breastfeeding support, such as a break period for expressing milk (p < 0.0001) and the availability of a refrigerator to store it (p = 0.01). Almost half the responding departments did not offer a lactation room where mothers could breastfeed or pump their milk. Measures must be envisioned to facilitate the pumping of breast milk by French women returning to work.

Cross-Cultural Adaptation and Psychometric Properties of the French Version of the EXIT to Measure Women's Experiences of Induction of Labor.

BACKGROUND: In France, more than 20% of women require induction of labor (IOL), which can be psychologically and emotionally challenging for patients. It is important to assess how they feel about their IOL experiences. Our aim was to cross-culturally adapt and evaluate the psychometric properties of a French version of the EXIT to assess women's experiences of IOL. METHODS: The EXIT was cross-culturally adapted by conducting forward and backward translations following international guidelines. A cross-sectional study was conducted to assess the psychometric properties of the ten French EXIT items: data completeness, factor analysis, internal consistency, score distribution, floor and ceiling effects, inter-subscale correlations, convergent validity, and test-retest reliability. RESULTS: The EXIT was successfully cross-culturally adapted to the French context and any IOL method. The results obtained from 163 patients requiring IOL showed good acceptability. Exploratory factor analysis resulted in a three-factor solution with subscales reflecting the experiential aspects of time taken to give birth, discomfort with IOL, and subsequent contractions. Good internal consistency (Cronbach's alpha or Spearman correlation coefficients ranging from 0.55 to 0.84) and good test-retest reliability (intraclass correlation coefficients ranging from 0.66 to 0.85) for the three identified subscales were found. CONCLUSIONS: The ten-item French EXIT is a valid and reliable instrument for the self-assessment of women's experiences of IOL in the three weeks following delivery for any method of IOL used. As a patient-reported outcome measure, it would allow the comparison of experiential outcomes across IOL studies in order to include women's preferences in decisions regarding their care.

Measuring the readiness to screen and manage intimate partner violence: Cross-cultural adaptation and psychometric evaluation of the PREMIS tool for perinatal care providers.

INTRODUCTION: Pregnancy and perinatal periods are significant risk factors of intimate partner violence (IPV), a major public health problem that could begin or intensify during these periods. Perinatal care providers have a major role in the identification and the management of IPV. This study aimed to cross-culturally adapt into French the Physician Readiness to Manage Intimate Partner Violence Survey (PREMIS) tool, a reliable instrument to assess the knowledge, attitudes and preparedness to address IPV, and to evaluate its psychometric properties. METHODS: The PREMIS was cross-culturally adapted by conducting forward and backward translations, following international guidelines. An online cross-sectional study was conducted to assess the psychometric properties of the PREMIS-French in perinatal care providers: data completeness, factor analysis, score distribution, floor and ceiling effects, internal consistency, item-total correlations, inter-subscale correlations and test-retest reliability. RESULTS: The PREMIS was successfully translated and cross-culturally adapted to the context of metropolitan France. The results obtained from 360 perinatal care providers showed good acceptability. Exploratory factor analysis of the "Opinions" items resulted in a six-factor solution with six of the eight subscales of the original structure identified. Good internal consistency (Cronbach's alpha ranging from 0.54 to 0.97) and good test-retest reliability (intraclass correlation coefficients ranging from 0.46 to 0.92) for the "Background" and "Opinions" subscales were found. DISCUSSION: This study provides evidence of the good psychometric properties of the PREMIS-French. This valid instrument will help to understand perinatal care providers' barriers to IPV screening and management and will help to focus on specific lacks of knowledge for developing IPV education programs.

Validation of the French Women Abuse Screening Tool to routinely identify intimate partner violence.

BACKGROUND: Health care professionals strongly underestimate the prevalence of intimate partner violence (IPV), and a few of them think that they screen and refer victims appropriately for assistance. The aim of this study was to cross-culturally validate a French version of the Woman Abuse Screening Tool (WAST). METHODS: A multicenter case-control study was performed in the forensic medicine unit of the University Hospital and two offices of the women's rights association in France. Abused and non-abused women self-completed the WAST and a questionnaire assessing their level of comfort in responding to the WAST during the study and during a hypothetical consultation with a physician in primary care. We analyzed the psychometric properties and screening performance of the WAST. RESULTS: Respondent acceptability was very good, with response rates exceeding 95%. The WAST had a good internal consistency (Cronbach α coefficient = 0.95). Its screening performance with a cut-off score of 5 was excellent: area under the ROC curve was 0.99, sensitivity 97.7%, specificity 97.1%, positive predictive value 97.2% and negative predictive value 97.7%. The levels of comfort were significantly lower among abused compared with non-abused women. Both groups of women were more comfortable answering the WAST during the study than in a hypothetical consultation. CONCLUSION: The French version of the WAST was found to be a well-accepted and valid screening tool for routine use in IPV. It may help health care professionals to detect women experiencing abuse early and to refer them more quickly to specific assistance.

Cost-effectiveness threshold of first-trimester Down syndrome maternal serum screening for the use of cell-free DNA as a second-tier screening test.

INTRODUCTION: We aimed to identify the most relevant cost-effectiveness threshold of first-trimester Down syndrome (DS) maternal serum screening (T21T1) for the use of cell-free DNA (cfDNA) as a second-tier test in the French context. METHOD: A cost-effectiveness analysis was performed on 108,121 singleton pregnancies using a simulation model. The threshold of T21T1 screening was ranged from 1/51 to 1/1,000 in steps of 1/50. The most relevant threshold was based on cost-effectiveness ratio (CER; costs = direct medical costs after T21T1 screening/ effectiveness = number of DS cases identified). RESULTS: In the sample, 161 cases of DS were identified. At the threshold of ≥ 1/50, 47.2% of total DS cases were diagnosed. In the simulation model, for a threshold ≥ 1/250, 73.9% of total DS cases were diagnosed, for ≥ 1/500, 78.8% and for ≥ 1/1,000, only two additional cases were diagnosed. The slope of the cost increase was slight from threshold ≥ 1/250 (978,634 €), then steep up to 1/500 (1,966,576 €) and increased exponentially to 1/1,000 (3,980,216 €). The CER was 38,560 for a threshold ≥ 1/500. CONCLUSION: The most cost-effective threshold for cfDNA as a second-tier test seems to be ≥ 1/500. For higher thresholds, costs increase dramatically for only a few additional cases of DS identified.

Is directed open-glottis pushing more effective than directed closed-glottis pushing during the second stage of labor? A pragmatic randomized trial - the EOLE study.

OBJECTIVE: To compare the effectiveness of directed open-glottis and directed closed-glottis pushing. DESIGN: Pragmatic, randomised, controlled, non-blinded superiority study. SETTINGS: Four French hospitals between July 2015 and June 2017 (2 academic hospitals and 2 general hospitals). PARTICIPANTS: 250 women in labour who had undergone standardised training in the two types of pushing with a singleton fetus in cephalic presentation at term (≥37 weeks) were included by midwives and randomised; 125 were allocated to each group. The exclusion criteria were previous caesarean birth or fetal heart rate anomaly. Participants were randomised during labour, after a cervical dilation ≥ 7 cm. INTERVENTIONS: In the intervention group, open-glottis pushing was defined as a prolonged exhalation contracting the abdominal muscles (pulling the stomach in) to help move the fetus down the birth canal. Closed-glottis pushing was defined as Valsalva pushing. MEASUREMENTS: The principal outcome was "effectiveness of pushing" defined as a spontaneous birth without any episiotomy, second-, third-, or fourth-degree perineal lesion. The results in our intention-to-treat analysis are reported as crude relative risks (RR) with their 95% confidence intervals. A multivariable analysis was used to take the relevant prognostic and confounding factors into account and obtain an adjusted relative risk (aRR). FINDINGS: In our intention-to-treat analysis, most characteristics were similar across groups including epidural analgesia (>95% in each group). The mean duration of the expulsion phase was longer among the open-glottis group (24.4 min ± 17.4 vs. 18.0 min ± 15.0, p=0.002). The two groups did not appear to differ in the effectiveness of their pushing (48.0% in the open-glottis group versus 55.2% in the closed-glottis group, for an adjusted relative risk (aRR) of 0.92, 95% confidence interval (CI) 0.74-1.14) or in their risk of instrumental birth (aRR 0.97, 95%CI 0.85-1.10). KEY CONCLUSIONS: In maternity units with a high rate of epidural analgesia, the effectiveness of the type of directed pushing does not appear to differ between the open- and closed-glottis groups. IMPLICATIONS FOR PRACTICE: If directed pushing is necessary, women should be able to choose the type of directed pushing they prefer to use during birth. Professionals must therefore be trained in both types so that they can adequately support women as they give birth.

Analysis of the cost effectiveness of different strategies for the antenatal diagnosis of chromosomal aberrations in cases of ultrasound-identified fetal abnormalities.

OBJECTIVE: Principal objective of this work was to analyse the cost effectiveness of different sequences of cytogenetic techniques from the hospital's point of view, after prenatal ultrasound has identified fetal malformations. METHODS: Cytogenetic tests were performed for each case in 3 strategies, and their results are reported and compared to one reference strategy. Two new simulated strategies were considered: chromosomal microarrays alone and a direct test + CMA. MAIN OUTCOMES MEASURES: cost-effectiveness ratio. RESULTS: A single test result was positive in 234 of the 835 pregnancies studied (28%). CMA alone would have identified 239 abnormalities. In the simulated direct test + CMA sequence, the direct test alone would have been positive for 66.1% of the abnormalities identified. When testing was indicated for NT, reference strategy (Direct + karyotyping) costs 1 084.8 euros by positive test results. Strategies Direct + CMA and CMA alone cost respectively 992.7 and 550.0 euros by positive test results. For OUM indications, reference strategy costs 2 937.8 euros by positive test results. Strategies Direct + CMA and CMA alone cost respectively, 2 118.4 and 1 304.7 euros by positive test results. CONCLUSIONS: CMA appears to be the most effective test for prenatal cytogenetic diagnosis of fetal abnormalities identified by ultrasound.

Nurses' practices in the preparation and administration of intramuscular injections in mental health: A cross-sectional study.

BACKGROUND: Intramuscular injections (IMIs) remain a frequent practice in mental health. Few studies have examined the issue of nurses' practices concerning IMI in this domain, and none considered specifically hygiene. Finally, no study appears to have looked at emergency situations and their possible influence on practices. The principal objective of our study was to assess the practices associated with IMI in mental health, especially the hygiene-related practices. The secondary objectives were as follows: 1) to assess the practices for the preparation and administration of IMI in mental health for criteria other than hygiene and 2) to determine whether professional experience and emergency situations influence these practices. DESIGN: Single-centre cross-sectional study in a psychiatric Hospital and adherence to the STROBE guidelines. METHODS: The participating nurses all worked with inpatients, and all volunteered for the study. A self-administered questionnaire was sent to all participants. The questionnaire included questions about knowledge and practices associated with IMI, some considered in two different situations: emergencies and planned injections. The distribution of the responses was tested by the chi-squared test or Fisher's exact test, as appropriate, or by McNemar's chi-squared test or Friedman's nonparametric chi-squared test for matched data. RESULTS: Response rate was 48.6%. Overall, 81% of nurses reported correct handwashing before preparation, 87.5% responded that the dorsogluteal site is currently recommended for IMI, and 74.6% that they did not know the "Z track" technique. In planned injections, 58.7% reported that the choice of needle was determined, at least in part, by the patient's body mass index. In emergency situations, adherence to guidelines was less frequent for all types of practices. CONCLUSIONS: This study shows the need to improve practices for the frequently used procedure of IMI among mental health nurses. RELEVANCE TO CLINICAL PRACTICE: Better professional education appears necessary to develop optimal practices, especially in emergency situations.

Fetal fibronectin test for threatened preterm delivery 48h after admission: Cost-effectiveness study.

OBJECTIVE: The aim of this work was to assess the cost-effectiveness of the fetal fibronectin (fFN) test at 48 h after admission for threatened preterm delivery to promote early discharge. STUDY DESIGN: Before-and-after study to calculate the incremental cost-effectiveness ratio (ICER). Patients were enrolled 48 h after admission in a tertiary care centre for threatened preterm delivery between 24+0 and 34+6 weeks. fFN testing was performed. During the first period, physician was blinded to fFN test and discharge occurred after apparent reduced symptomatology at physician's discretion. During the second period, fFN test was revealed to physician and discharge was immediately proposed to negative test patients. The costs considered in this analysis were the direct medical costs from the hospital perspective: costs of hospitalisation, treatment, and imaging procedures. The efficacy criterion selected was the number of deliveries at 7 and at 14 days after admission for threatened preterm delivery. RESULTS: The study included 178 pregnant patient, 99 during the first period (July 2008-October 2009) and 79 during the second (March 2010-February 2012). The lengths of hospital stays were shorter during the second period, with more than 50% of women discharged home between 48 and 72 h (p < 0.0001) resulting in a cost-saving of 76 051 euros. The number of deliveries at 7 and at 14 days was similar between the two periods. CONCLUSION: The fFN test at 48 h after admission supported early discharge and was safe and cost-effective.

Practices during the active second stage of labor: A survey of French midwives.

OBJECTIVE: the principal objective of our study was to describe the practices reported by French midwives during the active second stage of labor (expulsion phase). DESIGN: this cross-sectional Internet survey questioned French midwives who attended at least one childbirth in 2013. SETTING: this open survey was posted on a website from June 15 through December 1, 2014. PARTICIPANTS: 1496 midwives from 377 maternity units participated in the study. MEASUREMENTS AND FINDINGS: the midwives most often reported suggesting horizontal positions during the active second stage (supine with footholds, lithotomy, lithotomy with knees turned in, or lateral positions). Non-horizontal positions were more often proposed by midwives in level I units (p<0.0001). Almost half the midwives responding (46.4%), especially those working in level III units (51.1%, p = 0.006), advised Valsalva pushing. The mean maximum pushing time was 35.3 minutes±12.8 minutes. Nearly all the midwives favored the 'hands on' technique at childbirth (91.4%), and 24% reported using warm compresses on the perineum at childbirth. KEY CONCLUSION: most midwives advised horizontal positions for childbirth. The practices of French midwives differed as a function of where they worked. The midwives, especially those in level III facilities, reported that they cannot always ensure 'physiological childbirth'. IMPLICATIONS FOR PRACTICE: the practices of French midwives must become more evidence-based. The development of professional guidelines for midwives in France appears essential. This study also helps to prioritise national training for midwives.

Do estimates of blood loss differ between student midwives and midwives? A multicenter cross-sectional study.

OBJECTIVE: the principal objective of this study was to assess the quality of blood loss estimates by midwives and student midwives. The secondary objectives were: to assess the intraobserver agreement of visual blood estimates and the rate of underestimation of blood loss by participants, and to estimate the sensitivity, specificity, and negative likelihood ratio of these estimates for clinically pertinent blood losses (≥ 500mL and ≥ 1000mL). DESIGN: multicenter cross-sectional study. SETTING: thirty-three French maternity units and 35 French midwifery schools participated in this study. PARTICIPANTS: volunteer French midwifery students (n = 463) and practicing midwives (n = 578). INTERVENTION: an online survey showed 16 randomly ordered photographs of 8 different simulated blood quantities (100, 150, 200, 300, 500, 850, 1000, and 1500mL) with a reference 50-mL image in each photo and asked participants to estimate the blood loss. The visual blood loss estimates were compared with Fisher's exact test. Intraobserver agreement for these estimates was assessed with a weighted kappa coefficient, and the negative predictive values (probability of no hemorrhage when visual estimate was negative) were calculated from prevalence rates in the literature. FINDINGS: of the 16,656 estimates obtained, 34.1% were accurate, 37.2% underestimated the quantity presented, and 28.7% overestimated it. Analyses of the intraobserver reproducibility between the two estimates of the same photograph showed that agreement was highest (weighted kappa ≥ 0.8) for the highest values (1000mL, 1500mL). For each volume considered, students underestimated blood loss more frequently than midwives. In both groups, the negative predictive values regarding postpartum hemorrhage (PPH) diagnosis (severe or not) were greater than 98%. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: student midwives tended to underestimate the quantity of blood loss more frequently than the midwives. Postpartum hemorrhage (≥ 500mL) was always identified, but severe postpartum hemorrhage (≥ 1000mL) was identified in fewer than half the cases. These results should be taken into account in training both student midwives and practicing professionals.

Positions during the first stage and the passive second stage of labor: A survey of French midwives.

OBJECTIVE: the objective of our study was to describe the practices reported by French midwives during labor (first stage and passive phase of the second stage). DESIGN: this cross-sectional internet questionnaire surveyed French midwives who attended at least one delivery in 2013. SETTING: this open survey was posted on a website from June 15 through December 1, 2014. PARTICIPANTS: 1496 midwives from 377 maternity units participated in the study. Nearly 93% of the midwives worked in an obstetric unit, 5.9% had a mixed practice, and 1.3% worked in private practice. MEASUREMENTS AND FINDINGS: during the first stage of labor, midwives reported suggesting that women without epidural analgesia use a birthing ball (98.1%) and that they walk around (97.4%). For women with epidural analgesia, most suggested motion in horizontal positions. Epidural analgesia was proposed more often by midwives from level II (75.7%) and level III (73.5%) maternity wards than by those at level 1 units (57.7%) (p<0.0001). The midwives preferred a lateral position during the first stage for women with epidural analgesia and during the second stage for women both with and without it. Midwives in practice for 5 years or less suggested a kneeling position for women with epidural analgesia more often than more experienced midwives. KEY CONCLUSION: the practices of French midwives vary with their place of practice and their experience. IMPLICATIONS FOR PRACTICE: to promote normal labor, French midwives must reappropriate vertical positions and analgesic alternatives to epidurals.

Prenatal exposure to persistent organic pollutants and organophosphate pesticides, and markers of glucose metabolism at birth.

BACKGROUND: Experimental evidence suggests that developmental exposure to persistent organic pollutants (POP) and to some non persistent pesticides may disrupt metabolic regulation of glucose metabolism and insulin secretion, and thereby contribute to the current epidemic of obesity and metabolic disorders. Quasi-experimental situations of undernutrition in utero have provided some information. However, the evidence in humans concerning the role of the prenatal environment in these disorders is contradictory, and little is known about long-term outcomes, such as type 2 diabetes, of prenatal exposure. OBJECTIVES: Our aim was to evaluate the effects of prenatal exposure to POP and organophosphate pesticides on fetal markers of glucose metabolism in a sample of newborns from the Pelagie mother-child cohort in Brittany (France). METHODS: Dialkylphosphate (DAP) metabolites of organophosphate pesticides were measured in maternal urine collected at the beginning of pregnancy. Cord blood was assayed for polychlorinated biphenyl congener 153 (PCB153), p,p'-dichlorodiphenyl dichloroethene (DDE) and other POP. Insulin and adiponectin were determined in cord blood serum (n=268). RESULTS: A decrease in adiponectin and insulin levels was observed with increasing levels of DDE, but only in girls and not boys. Adiponectin levels were not related to the concentrations of other POP or DAP metabolites. Decreasing insulin levels were observed with increasing PCB153 concentrations. Insulin levels increased with DAP urinary levels. Additional adjustment for BMI z-score at birth modified some of these relations. CONCLUSIONS: Our observations bring support for a potential role of organophosphate pesticides and POP in alterations to glucose metabolism observable at birth.
