Dietary exposure to mixtures of chemicals in the first year of life and allergic and respiratory diseases up to 8 years in the French EDEN mother-child cohort.

Exposure to environmental chemicals has been associated with higher risk of childhood allergies. This study aimed to examine the association between infant's dietary exposure to mixtures of chemicals and allergic and respiratory multimorbidity in childhood. Dietary exposures were assessed at 8 and 12 months in 724 and 745 children of the EDEN cohort.

A preliminary estimate of the environmental burden of disease associated with exposure to pyrethroid insecticides and ADHD in Europe based on human biomonitoring.

Human biomonitoring (HBM) data indicate that exposure to pyrethroids is widespread in Europe, with significantly higher exposure observed in children compared to adults. Epidemiological, toxicological, and mechanistic studies raise concerns for potential human health effects, particularly, behavioral effects such as attention deficit hyperactivity disorder (ADHD) in children at low levels of exposure. Based on an exposure-response function from a single European study and on available quality-assured and harmonized HBM data collected in France, Germany, Iceland, Switzerland, and Israel, a preliminary estimate of the environmental burden of disease for ADHD associated with pyrethroid exposure was made for individuals aged 0-19 years.

Bio-functionalized hydrogel patches of chitosan for the functional recovery of infarcted myocardial tissue.

The aim of this work was to assess the potential benefits of the enrichment of a chitosan hydrogel patch with secretome and its epicardial implantation in a murine model of chronic ischemia, focusing on the potential to restore the functional capacity of the heart. Thus, a hydrogel with a final polymer concentration of 3 % was prepared from chitosan with an acetylation degree of 24 % and then bio-functionalized with a secretome produced by mesenchymal stromal cells. The identification of proteins in the secretomes showed the presence of several proteins known to have beneficial effects on cardiac muscle repair.

Identification of pesticide mixtures to which French agricultural workers and farm-owners are exposed: Results from the Agriculture and Cancer (AGRICAN) cohort study.

Farmers, particularly in Europe, are exposed to multiple pesticides during their working life. Such exposures can cause adverse health outcomes. We aimed to identify the main pesticide mixtures to which French agricultural workers are exposed and to classify farmers into clusters based on their mixture exposure profile.
