Objective: To provide practical recommendations for evaluation and treatment of osteoporosis associated to endocrine diseases and nutritional conditions., Participants: Members of the Bone Metabolism Working Group of the Spanish Society of Endocrinology, a methodologist, and a documentalist., Methods: Recommendations were formulated according to the GRADE system (Grading of Recommendations, Assessment, Development, and Evaluation) to describe both the strength of recommendations and the quality of evidence. A systematic search was made in MEDLINE (Pubmed), using the following terms associated to the name of each condition: AND "osteoporosis", "fractures", "bone mineral density", and "treatment". Papers in English with publication date before 18 October 2011 were included. Current evidence for each disease was reviewed by two group members, and doubts related to the review process or development of recommendations were resolved by the methodologist. Finally, recommendations were discussed in a meeting of the Working Group., Conclusions: The document provides evidence-based practical recommendations for evaluation and management of endocrine and nutritional diseases associated to low bone mass or an increased risk of fracture. For each disease, the associated risk of low bone mass and fragility fractures is given, recommendations for bone mass assessment are provided, and treatment options that have shown to be effective for increasing bone mass and/or to decreasing fragility fractures are listed., (Copyright © 2012 SEEN.

Background and Objective: Nutritional assessment in the elderly is difficult and different from that performed in younger people. There are specific tools for that purpose, such as the Geriatric Nutritional Risk Index (GNRI). The study objective was to compare this index to the Nutritional Risk Index (NRI)., Materials and Methods: A retrospective, observational analytical study including 113 hospitalized patients over 75 years of age receiving nutritional support. Weight, height, age, length of stay, Mini Nutritional Assessment (MNA), nutrition type and duration, and occurrence of complications were collected. GNRI and NRI were calculated. Both indexes were compared to each other and with parameters measured., Results: Mean GNRI was 88.79 (SD: 13.1), mean NRI 79.96 (SD: 10.8), and mean MNA 17.49 (SD: 4.9). Complications occurred in 50.4% of patients, and 14% died. NRI and GNRI did not correlate with length of stay (R=0.136) or with length of nutrition (R=0.041). No significant correlation was seen between GNRI and complications, but a significant relationship was found with NRI. After stratification into surgical and medical patients, NRI was seen to be significantly related to complications in surgical patients only (p<0.05). GNRI was not related to complications in either surgical or medical patients., Conclusions: In hospitalized elderly patients, NRI is a better predictor of complications and may be more appropriate for assessing the risk of death than GNRI. GNRI underestimated nutritional risk as compared to NRI., (Copyright © 2010 SEEN. Published by Elsevier Espana. All rights reserved.)
