Objective: The increasing resistance of Helicobacter pylori to clarithromycin led to developing new eradication treatment regimens. The objective of our observational study was to determine the proportion of H. pylori strains resistant to clarithromycin in infected patients in Reunion Island and to suggest a first-line treatment in agreement with the local ecology.
Patients And Methods: We included 200 patients who underwent esophagogastroduodenoscopy at the University Hospital of Saint-Pierre from February to July 2014. H. pylori was isolated from 73 patients.
Results: A wild-type susceptibility profile to clarithromycin was observed in 64 isolates (87.7%) and nine isolates (12.3%) had a resistant mutation profile.
Conclusion: With a proportion of resistant strains below the critical threshold of 15%, physicians in Reunion Island may continue to prescribe the usual treatment regimen as a first-line option (clarithromycin, amoxicillin, and proton pump inhibitor for 14 days).

The French Agency for Food, Environmental and Occupational Health & Safety (Anses) has set up a multidisciplinary working group (WG) to develop an innovative One Health approach for the monitoring and evaluation of an integrated vector management system (IVMS) on a territorial scale. Four existing evaluation guidelines and methods have been combined into a semi-quantitative evaluation approach that takes into account all the dimensions of an integrated process. We propose a set of 34 criteria divided into three sections (objectives and management, implementation, integration) that correspond to the main functional components of an IVMS.

Children are expected to outlive and live longer than their parents. However, the traumatic death of a child challenges parents' understanding of life and death. If parents are unable to form their own perceptions of death after such a loss, it can hinder their ability to cope and adjust.

Citizen Science initiatives have a worldwide impact on environmental research by providing data at a global scale and high resolution. Mapping marine biodiversity remains a key challenge to which citizen initiatives can contribute. Here we describe a dataset made of both underwater and aerial imagery collected in shallow tropical coastal areas by using various low cost platforms operated either by citizens or researchers.

The Société de Pathologie Infectieuse de Langue Française released in 2024 a new national recommendation for clinical practice on the prevention and management of varicella zoster virus (VZV) infection during pregnancy and the perinatal period. The previous recommendation was issued in 1998, at a time of anti-VZV immunoglobulins shortage; it has hence become obsolete. This recommendation is a formalized expert consensus focusing on infectious diseases management; it is drawn up by a multidisciplinary working group (infectiologists, obstetricians, pediatricians, microbiologists, midwives, hygienists).
