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.

Protocol for the e-POWUS Project: multicentre blinded-randomised controlled trial of ultrasound speed choice to improve sonography quality in pregnant women with obesity.

Introduction: During pregnancy, maternal obesity increases the risk of fetal abnormalities. Despite advances in ultrasound imaging, the assessment of fetal anatomy is less thorough among these women. Currently, the construction of ultrasound images uses a conventional ultrasound propagation velocity (1540 m/s), which does not correspond to the slower speed of propagation in fat tissue.

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.

A French audit of maternity unit protocols for immediate postpartum hemorrhage: A cross-sectional study (HERA).

Objectives: The principal objective of this work was to assess how well the written protocols of maternity units used for the prevention and management of postpartum hemorrhage (PPH) corresponded to the 2004 French guidelines on this topic. The second objective was to assess whether or not this correspondence with the national guidelines varied according to hospital level (basic, specialized, and subspecialized) and status (teaching, public, and private).

Methods: This observational multicenter cross-sectional study took place in September 2010 and included French perinatal networks that volunteered to participate.

Temperature Elevation in an Instrumented Phantom Insonated by B-Mode Imaging, Pulse Doppler and Shear Wave Elastography.

Diagnostic ultrasound is the gold standard for obstetric scanning and one of the most important imaging techniques for perinatal and neonatal monitoring and diagnosis. Ultrasound provides detailed real-time anatomic information, including blood flow measurements and tissue elasticity. The latter is provided through various techniques including shear wave elastography (SWE).

Temperature Rise Caused by Shear Wave Elastography, Pulse Doppler and B-Mode in Biological Tissue: An Infrared Thermographic Approach.

The aim of this study was to determine the interest in and relevance of the use of infrared thermography, which is a non-invasive full-field surface temperature measurement technique, to characterize the heterogeneous heating caused by ultrasound in biological tissue. Thermal effects of shear wave elastography, pulse Doppler and B-mode were evidenced in porcine tissue. Experiments were performed using a high-frequency echography Aixplorer system (Supersonic Imagine, Aix-en-Provence, France).

Phthalate Exposure in Pregnant Women: Risk Perception and Preventive Advice of Perinatal Health Professionals.

Objectives The main objective of the PERI-HELPE study (Perception of Risk-HEaLth Professionals and Environment Study) was to describe the knowledge of perinatal health professionals about phthalates and the preventive advice they give to pregnant women about exposure to these chemicals. The secondary objective was to determine whether giving preventive advice was associated with the perception of phthalates. Methods A cross-sectional study was performed in 2015 in France.

Laryngotracheoesophageal cleft, a rare differential diagnosis of esophageal atresia.

A laryngotracheoesophageal cleft, commonly called laryngeal cleft (LC), is a congenital malformation of the posterior part of the larynx creating an abnormal communication between the laryngotracheal axis and the pharyngoesophageal axis. The prenatal ultrasonographic features associating absent stomach, polyhydramnios and mediastinal "pouch sign" are usually considered pathognomonic for esophageal atresia. This observation demonstrates that they can also correspond to a severe form of laryngotracheoesophageal cleft extending to the carina.

In utero exposure to arsenic in tap water and congenital anomalies: A French semi-ecological study.

Introduction: Congenital anomalies (CA) are responsible for high rates of mortality and long-term disabilities. Research on their risk factors including environmental factors is needed. Studies on exposure to arsenic (As) in tap water and the risk of CA have not provided conclusive evidence, particularly when levels of exposure were low (from 10 to 50 μg As/L).

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.

Exposure to arsenic in tap water and gestational diabetes: A French semi-ecological study.

Introduction: The increase in the prevalence of gestational diabetes mellitus (GDM) and its consequences for mother and children prompts research on their risk factors including environmental factors. Studies on exposure to arsenic (As) in tap water and the risk of GDM have not provided conclusive evidence, particularly when levels of exposure were low (from 10 to 50µg As/L). The main objective of this study was to assess the association between exposure to As in tap water and the risk of GDM.

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.

Congenital unilateral renal agenesis: Prevalence, prenatal diagnosis, associated anomalies. Data from two birth-defect registries.

Background: The different mechanisms leading to a solitary kidney should be differentiated because the long-term outcome might be different. The fetal period is the best moment to make a true diagnosis of congenital unilateral renal agenesis (URA). The objective was to determine the prevalence of URA at birth.

Exposure of hospitalised pregnant women to plasticizers contained in medical devices.

Background: Medical devices (MDs) in polyvinyl chloride (PVC) are not a well-known source of exposure to plasticizers, in particular during pregnancy. Because of its toxicity, the di-(2-ethylhexyl) phthalate (DEHP) has been replaced by other plasticizers such as di (isononyl)-cyclohexane-1,2-dicarboxilic acid (DINCH), tri-octyltrimellitate (TOTM) and di-(isononyl) phthalate (DiNP). Our study aimed to quantify the plasticizers (DEHP and alternative plasticizers) contained in PVC medical devices used for hospitalised pregnant women and to describe which these MDs had been used (type, number, duration of exposure).

Perception of Environmental Risks and Health Promotion Attitudes of French Perinatal Health Professionals.

The exposure of pregnant women to environmental contaminants is a subject of international concern. However, the risk perception of these contaminants by health professionals (HP) has not been extensively investigated. The main objective of the PERI-HELPE study (Perception of Risk-HEaLth Professionals & Environment Study) was to assess the risk perception of environmental exposure of pregnant women by perinatal HPs.

Policies for management of postpartum haemorrhage: the HERA cross-sectional study in France.

Objective: The principal objective of this study was to describe the policies reported by French maternity units for the prevention and early management of postpartum haemorrhage (PPH). The second objective was to assess their variation according to hospital level and status.

Study Design: Cross-sectional observational study of French maternity units, from January 2010 to April 2011.

Incidence of immediate postpartum hemorrhages in French maternity units: a prospective observational study (HERA study).

Background: Most estimates of postpartum hemorrhage (PPH) are calculated from studies that use administrative or medical birth databases, and only a few from prospective observational studies. Our principal objective was to estimate the incidence of PPH according to their severity (mild or severe) in vaginal deliveries (>500 mL, ≥1000 mL) and cesareans (>1000 mL and ≥1500 mL). The secondary objectives were to describe the incidence of PPH according to maternity unit characteristics, causes, and types of PPH management.

Does maternal race influence the short-term variation of the fetal heart rate? An historical cohort study.

Objectives: The main aim of this article was to analyze short-term variation (STV) of the fetal heart rate according to maternal race. The secondary aim was to study the baseline fetal heart rate according to this factor.

Study Design: This single-center historical cohort study covered the period from November 2008 through December 2011 (n=182).

Reliability of student midwives' visual estimate of blood loss in the immediate postpartum period: a cross-sectional study.

Background: In France, postpartum hemorrhage (blood loss≥500mL in the first 24h postpartum) is the leading direct obstetric cause of maternal mortality. In French practice, PPH is mainly diagnosed by a quantitative assessment of blood loss, performed by subjective methods such as visual estimates. Various studies have concluded that visual estimates are imprecise, tend to underestimate blood loss, and thus to delay diagnosis of PPH.

Prenatal Screening of 21 Microdeletion/Microduplication Syndromes and Subtelomeric Imbalances by MLPA in Fetuses with Increased Nuchal Translucency and Normal Karyotype.

Fetuses with increased nuchal translucency thickness (NT) are at increased risk for chromosomal abnormalities. In case of a normal karyotype, a minority of them may present with structural abnormalities or genetic syndromes, which may be related to submicroscopic chromosomal imbalances. The objective of this study was to evaluate whether MLPA screening of 21 syndromic and subtelomeric regions could improve the detection rate of small chromosomal aberrations in fetuses with increased NT and a normal karyotype.
