Differences in Malnutrition Inflammation Score of Hemodialysis Patients Associated With Hemodialysis Factors. A Spanish Multicenter Epidemiologic Study.

Objectives: The aims of this study are to analyze the prevalence of malnutrition in hemodialysis (HD) patients in Spain, and to assess the association of malnutrition in these patients with sociodemographic characteristics, comorbidity, and parameters related to HD.

Design And Methods: A multicenter, retrospective, cross-sectional study in HD patients from centers all over Spain was conducted. Nutritional status of patients was assessed using Malnutrition Inflammation Score (MIS), and was stratified according to MIS values into 5 categories: ≤2, normal nutrition; >2 to ≤5, mild malnutrition or risk of malnutrition; >5 to ≤7, moderate malnutrition; >7 to ≤10, severe malnutrition, and >10, extreme malnutrition.

CAOS-CMOS camera.

Proposed and experimentally demonstrated is the CAOS-CMOS camera design that combines the coded access optical sensor (CAOS) imager platform with the CMOS multi-pixel optical sensor. The unique CAOS-CMOS camera engages the classic CMOS sensor light staring mode with the time-frequency-space agile pixel CAOS imager mode within one programmable optical unit to realize a high dynamic range imager for extreme light contrast conditions. The experimentally demonstrated CAOS-CMOS camera is built using a digital micromirror device, a silicon point-photo-detector with a variable gain amplifier, and a silicon CMOS sensor with a maximum rated 51.

"Viral déjà vu" elicits organ-specific immune disease independent of reactivity to self.

Autoimmune diseases are often precipitated by viral infections. Yet our current understanding fails to explain how viruses trigger organ-specific autoimmunity despite thymic tolerance extending to many non-lymphohematopoietic self antigens. Additionally, a key epidemiological finding needs to be explained: In genetically susceptible individuals, early childhood infections seem to predispose them to multiple sclerosis (MS) or type 1 diabetes years or even decades before clinical onset.
