Shielding Parenteral Nutrition Solutions From Light: A Randomized Controlled Trial.

Introduction: Oxidant stress is implicated in the pathogenesis of bronchopulmonary dysplasia (BPD). Light induces peroxide generation in parenteral nutrition (PN) solutions, creating an oxidant stress. Shielding PN from light decreases its peroxide content, which has nutrition and biochemical benefits in animals and humans.

Methodological validation of monitoring indicators of antibiotics use in hospitals.

Background: For several years now, the French national recommendations have been trying to set up a surveillance system in hospitals to link data on antibiotic resistance and data on the use of antibiotics, particularly for certain 'micro-organism/antibiotic' pairs. The indicators recommended in the lastest newsletter of the Direction Générale de la Santé (French Public Health Department) for monitoring the consumption of antibiotics were the number of days of treatment or the number of defined daily doses (DDD), both (in)directly related to the number of days of hospitalisation and/or the number of patients hospitalised.

Objective: The aim of this study was to compare the actual number of days of treatment, which is an observed indicator, with two indicators calculated on the basis of the DDD and the DPD (daily prescribed dose), both in terms of feasibility of collection and the relevance of the information generated.
