Perinatal Environmental Health Education Intervention to Reduce Exposure to Endocrine Disruptors: The PREVED Project.

Environmental health promotion interventions may reduce endocrine disruptor (ED) exposure. The PREVED (PREgnancy, preVention, Endocrine Disruptors) project was developed to improve knowledge, to enhance risk perception, and to change exposure behavior. Our objective was to present the phases of the PREVED project using the RE-AIM method.

Impact of perinatal environmental health education intervention on exposure to endocrine disruptors during pregnancy-PREVED study: study protocol for a randomized controlled trial.

Background: The suspected or actual effects on health of endocrine-disrupting chemicals (EDC) and their ubiquitous presence in everyday life justify the implementation of health promotion interventions. These interventions should ideally be applied during critical windows like pregnancy. Perinatal environmental health education interventions may help to reduce EDC exposure during pregnancy.

Positioning Digital Tracing Applications in the Management of the COVID-19 Pandemic in France.

To combat the COVID-19 pandemic, many European countries have developed a public health strategy involving the use of digital contact tracing (DCT) applications to improve timely tracking and contact tracing of COVID-19 cases. France's independent COVID-19 Control and Society Connection Council (CCL) was established by law in May 2020 to issue advice and recommendations on the national epidemic digital systems. In this paper, we present the recommendations by the CCL, with the objective to increase the uptake and utility of French DCT applications.

Comparison of the Effect on Fetal Growth of a Mixture of Atrazine and Nitrates in Drinking Water and of Active Tobacco Exposure during Pregnancy.

Active tobacco exposure during pregnancy is a known determinant of fetal growth. Nitrates and atrazine metabolites in drinking water may affect fetal growth as a mixture of endocrine disruptors (ED). We aimed to determine whether EDC have an additional effect on fetal growth compared to active tobacco exposure.

How to Educate Pregnant Women about Endocrine Disruptors?

Despite mediatization, only half of pregnant women are informed about endocrine disruptors (EDs). We wished to inquire about appropriate environmental health education procedures during pregnancy: Who, when, and how? The question stems from a comprehensive population health intervention research project. It includes qualitative studies aimed at constructing an educational program in environmental health and an accompanying assessment tool.

Simultaneous determination of bisphenol A and its chlorinated derivatives in human plasma: Development, validation and application of a UHPLC-MS/MS method.

Bisphenol A (BPA) is a well-known ubiquitous chemical found in polycarbonate, polysulfone and epoxy resins, used in mass production for many consumer products. BPA exhibits endocrine disruptor properties that can potentially induce adverse health effects. In aquatic environments, it can react with chlorine to produce chlorinated derivatives (ClxBPAs).

Environmental Health Knowledge, Attitudes, and Practices of French Prenatal Professionals Working with a Socially Underprivileged Population: A Qualitative Study.

Unlabelled: Introduction: As environmental health knowledge of population is associated with social economic status, the objective of this study was to determine environmental health knowledge, attitudes, and practices of French prenatal professionals working with a socially underprivileged population.

Material And Methods: A focus group with eleven prenatal professionals working with socially underprivileged population was carried out in France in 2015. Content analysis of verbatim explanation was conducted with choice-of-subject categories carried out according to the triangulation principle, and topic trees were generated and applied.

Bisphenol A, Chlorinated Derivatives of Bisphenol A and Occurrence of Myocardial Infarction in Patients with Type 2 Diabetes: Nested Case-Control Studies in Two European Cohorts.

A positive association between Bisphenol A (BPA) exposure and coronary heart disease has been shown, but not in patients with type 2 diabetes (T2D). During the treatment of drinking water, chlorination leads to the formation of chlorinated derivatives of Bisphenol A (ClxBPA), that have higher estrogenic activity than BPA. No evidence exists for a relationship between exposure to ClxBPA and myocardial infarction in patients with T2D.

Determinants of Risk Perception Related to Exposure to Endocrine Disruptors during Pregnancy: A Qualitative and Quantitative Study on French Women.

Endocrine disruptors (EDCs) are known as environmental exposure factors. However, they are rarely reported by health professionals in clinical practice, particularly during pregnancy, even though they are associated with many deleterious consequences. The objectives of this study were to estimate the risk perception of pregnant women related to EDC exposure and to evaluate its determinants.

Endocrine Disruptors and Pregnancy: Knowledge, Attitudes and Prevention Behaviors of French Women.

Endocrine disrupting chemicals (EDC) are environmental exposure factors that are rarely reported in clinical practice, particularly during pregnancy. This study aimed to describe women's knowledge, attitudes and behaviors towards EDC exposure. A study was conducted in the French Department of Vienne between 2014 and 2016 and comprised semi-structured interviews with pregnant women, a focus group of professionals in perinatology and environmental health, and the administration of a psychosocial questionnaire comprising scores in 300 pregnant or in postpartum period women.

Validation of a probe for assessing deconjugation of glucuronide and sulfate phase II metabolites assayed through LC-MS/MS in biological matrices.

LC-MS/MS has been proposed in various areas such as Therapeutic Drug Monitoring (TDM), Human Biomonitoring (HBM), disease diagnosis, clinical toxicology and doping control to identify and quantify chemical parents and their metabolites in biological matrices. To determine the total content of a xenobiotic (unconjugated+conjugated forms), an enzymatic hydrolysis step is required. Most studies in the literature have not controlled the effectiveness of the deconjugation process because no method has been described for that purpose.

Association between Exposure to Endocrine Disruptors in Drinking Water and Preterm Birth, Taking Neighborhood Deprivation into Account: A Historic Cohort Study.

Background: The relationship between preterm birth (PTB) and endocrine disruptor exposure in drinking-water has only occasionally been studied. The objective of this work was to investigate the relation between exposure to atrazine metabolites, or atrazine/nitrate mixtures, in drinking-water during pregnancy and prevalence of PTB neonates, while taking neighborhood deprivation into account.

Method: A historic cohort study in Deux-Sèvres, France, between 2005 and 2010 with a multiple imputation model for data of exposure to atrazine metabolites and a logistic regression were carried out.

Estimating drinking-water ingestion and dermal contact with water in a French population of pregnant women: the EDDS cohort study.

The aim of the present study, a part of the Endocrine Disruptor Deux-Sèvres (EDDS) cohort study, was to estimate water-use habits of pregnant French women. The study population consisted of 132 pregnant women living in Deux-Sèvres (France) in 2012-2013, in areas where drinking water is exclusively produced by surface water. Drinking-water data included ingested water (tap, bottled and filtered) and ingestion place (home, work and elsewhere).

Bisphenol a and its chlorinated derivatives in human colostrum.

The health effects related to bisphenol A (BPA) and its exposure sources have undergone extensive investigation, but no consensus has been reached. Hitherto, the major source of human BPA exposure considered in the literature remains food-contact material. However, the chlorine present in drinking water may react with BPA to form chlorinated derivatives (ClxBPA), which have indeed been shown to have a heightened level of estrogenic activity.

Reliable quantification of bisphenol A and its chlorinated derivatives in human breast milk using UPLC-MS/MS method.

Bisphenol A is a widespread industrial chemical which over the past decade has demonstrated its toxicity as an endocrine disruptor. Chlorine present in drinking water may react with bisphenol A to form chlorinated derivatives, which have demonstrated a heightened level of estrogenic activity. In this work, we have comprehensively validated a method using on-line SPE-UPLC-MS/MS and isotope dilution quantification to measure bisphenol A and its chlorinated derivatives in human breast milk according to accepted guidelines.

Quantification of bisphenol A, 353-nonylphenol and their chlorinated derivatives in drinking water treatment plants.

Bisphenol A (BPA) and nonylphenols (NP) are of major concern to public health due to their high potential for human exposure and to their demonstrated toxicity (endocrine disruptor effect). A limited number of studies have shown that BPA and NP are present in drinking water. The chlorinated derivatives that may be formed during the chlorination step in drinking water treatment plants (DWTP) exhibit a higher level of estrogenic activity than their parent compounds.

[Adequacy between prescriptions and CHADS(2) score recommendations in geriatric patients].

Unlabelled: Atrial fibrillation (AF) is a major risk factor for stroke. Thromboprophylaxis with anticoagulant reduces the incidence of stroke and is warranted by the CHADS(2) recommendations when score ≥2. But such therapy remains underused particularly among elderly patients.

Improving perinatal Group B streptococcus screening with process indicators.

Rationale: Group B streptococcus (GBS) neonatal infection can be prevented by screening pregnant women for GBS colonization from the 34th to the 38th week of gestation, as has been recommended in France since 2001. We assessed guideline adherence among midwives and obstetricians.

Methods: From 2006 to 2008, new and mandatory GBS data were added to the obstetric database.
