Épidémiologie des tumeurs neuroendocrines intestinales
2017
International audience; Few data are available about the epidemiology of digestive neuroendocrine tumours (NETs). Malignant digestive (MD) NETs remain as a rare cancer representing 1 % of digestive cancers. In France, the incidence rates of MD-NETs are estimated to around 1.1/100,000 inhabitants in males and 0.9/100,000 in females which then increased over time, with probably more than 1,000 new cases per year. Due to the relative good prognosis, NETs are the second more prevalent digestive cancer next to colorectal cancer. Most gastroenteropancreatic NETs are well-differentiated (WD-NETs); poorly differentiated neuroendocrine carcinomas (PDNEC) account for less than 20% of the cases in mos…
Epidemiology of Multiple Sclerosis en France
2012
In Europe, France is located between high and low risk areas of Multiple Sclerosis (MS). We estimated the national prevalence of MS in France on 31st October 2004 and the incidence between 2000 and 2007 based on data from the ‘Caisse Nationale d’Assurance Maladie des Travailleurs Salariés’ which insures 87% of the population. MS like other chronic diseases is one of the 30 long-term illnesses (Affections de Longue Durée, ALD). We analysed geographic variations in the prevalence and incidence of MS in France using the Bayesian approach.Total MS prevalence in France standardised for age was 94.7 per 100,000; 130.5 in women; 54.8 in men. The notification rate for MS (2000-2007) after age-stand…
Fragmentation des habitats et interactions hôtes-parasites
2021
Habitat fragmentation is one of the main threats to global biodiversity and despite an abundant literature on the impact of fragmentation on species abundance and diversity, the consequences of this global change in terms of ecological and evolutionary processes remain poorly understood. Beyond their direct contribution to biodiversity, as species-rich category of organisms, parasites could be involved in biodiversity change as key actors of ecological and evolutionary processes. The present work aims to understand the effect of forest fragmentation on host-parasite interactions. It is based on a large sampling carried out in the Lesser Antilles and in French Guiana, and allowing the obtent…
Prévalence et circulation de pathogènes humains et de bactéries résistantes aux antibiotiques dans l'environnement
2012
National audience; Les sols constituent un réservoir important de biodiversité microbienne. Parmi ces microorganismes, certains sont capables d’interactions avec l’Homme (commensalisme) ou d’induire des pathologies (maladies infectieuses aigues ou chroniques). De plus, les bactéries du sol constituent un réservoir important de gènes de résistance aux antibiotiques. Les activités agricoles comme l’élevage et le recyclage de produits résiduaires organiques dans les sols peuvent constituer une source de bactéries pathogènes, résistantes aux antibiotiques ou commensales de l’Homme. Ces pratiques agricoles, qui sont en constante évolution, doivent donc aussi être évaluées en termes de risque san…
