Audit about Medical Decision: Data Transmission Concerning Patients with Dementia Entering French Nursing Homes Does Not Confirm the Diagnosis

Background. Dementia was affecting 855.000 patients in France in 2007. Lanmeur's rural hospital population was representative of the French nursing home's population. The followup was assumed by local GPs, which is also usual care in France for nursing homes. The study looked at clinical and paraclinical data transmitted at the institutionalization time of patients suffering from dementia. Aim. showing that admission letters did allow establishing a diagnosis of dementia for the GPs. Method. we included all patients with dementia at the time of institutionalization between July 2000 and July 2007. We searched in the admission letters for 25 criteria extracted from the French guidelines for dementia and Alzheimer disease diagnosis (multiple cross-sectional analysis per year). Results. 293 patients were included. The median number of diagnostic criteria present in the letters of admission is 1 (first quartile: zero, third quartile: 4, and maximum: 12). Conclusions. the data in admission letters did not allow the diagnosis of dementia according to the French guidelines. We know that dementia is underchecked and undertreated in France according to the same guidelines. What consequences did this lack of basic data give on motivation for treatment and recurrent diagnosis process for GPs? This has to be evaluated

Fibres optiques dopées aux terres rares et amplificateurs optiques pour applications spatiales

International audienceDes outils de simulation multi-physiques des nous permettent de prédire les performances d’un amplificateur optique à base de fibre active Er ou Er/Yb en terme de gain et de bruit. Les travaux présentés visent à implémenter un module additionnel en vue de prédire leur comportement sous irradiation. Dans sa version publiée, les pertes induites par l’irradiation sont les seuls paramètres pris en compte dans ce module. Dans cet article, nous étudions l’influence d’une altération sous irradiation des autres paramètres spectroscopiques sur le gain et le bruit de l’amplification afin d’identifier les optimisations les plus pertinentes pour nos codes de calcu

Realization and Numerical Simulation of a High Power and High Efficiency Holmium Doped Fiber Laser at 2.1 μm

International audienceHolmium fiber lasers pumped in-band with Tm fiber lasers appear as interesting solutions when looking for high power in a single spatial mode and high electro-optic efficiency, in a spectral domain that guarantees eye-safe emission and low absorption by the atmosphere. We will present the progress of our work on a high efficiency holmium (Ho) fiber laser, detailing the numeric model, experimental realization and results
