BACKGROUND & AIMS The reported frequency of disease-related malnutrition (DRM) for patients admitted to hospitals has been shown to be high, but an accurate estimate of the magnitude of its economic costs is lacking. The objective of this study was to determine the impact of DRM on hospitalization costs. METHODS A probabilistic sample of 469 (50%)(More)
The Amazon area has been increasingly suffering from anthropogenic impacts, especially due to the construction of hydroelectric power plant reservoirs. The analysis and categorization of the trophic status of these reservoirs are of interest to indicate man-made changes in the environment. In this context, the present study aimed to categorize the trophic(More)
BACKGROUND & AIMS The identification of modifiable risk factors associated with disease-related undernutrition at hospital admission will contribute to the development of integrated intervention and control strategies for a timely primary prevention. This study aim was to quantify the association between functional autonomy and undernutrition. METHODS A(More)
BACKGROUND Data on red blood cell (RBC) transfusion in the United States show variation in practice and overprescribing or overdosing is considered to be prevalent. Education or restrictive interventions could modify practice. STUDY DESIGN AND METHODS RBC transfusion and mortality rates were recorded in a single institution over a 15-year period. The(More)
(-)-Agelasidine A was identified from the methanol extract of the marine sponge Agelas clathrodes for the first time together with zooanemonin, 1-carboxymethylnicotinic acid, hymenidin, mukanadins A and C, monobromodispacamide, agelasidine D, 2-amide-4-bromopyrrole, O-methyltryptophan and an agelasines mixture. The structures were characterized by(More)
Objective:To investigate if handgrip strength (HGS) could be used as a single screening procedure in identifying patients who are classified as being undernourished or nutritionally-at-risk at hospital admission.Design:Cross-sectional study. In the second day of hospital admission, HGS was evaluated and results were compared with Nutritional Risk Screening(More)
AIM The aim of our study was to evaluate the inadequacy of voluntary energy and nutrient intake on the first day of hospital admission. PATIENTS AND METHODS A cross-sectional study was carried out in two terciary care hospitals, with a probabilistic sample of 50% of in-patients. Dietary intake was evaluated by a 24-hour dietary recall, and undernutrition(More)
The prevalence of disease-related malnutrition (DRM) is described to be of 30-60% on admission to hospital, and of 10% in the community. It has been associated with worse clinical outcomes, namely higher morbidity and mortality as well as higher frequency of health care and its associated costs. The lack of screening and monitoring of nutritional status(More)
