Liver transplantation (LT) is a major surgery performed on patients with end stage liver disease. Nutrition is an integral part of patient care, and protein-energy malnutrition is almost universally present in patients suffering from liver disease undergoing LT. Nutrition assessment of preliver transplant phase helps to make a good nutrition care plan for the patients. Nutrition status has been associated with various factors which are related to the success of liver transplant such as morbidity, mortality, and length of hospital stay. To assess the nutritional status of preliver transplant patients, combinations of nutrition assessment methods should be used like subjective global assessment, Anthropometry mid arm-muscle circumference, Bioelectrical impedance analysis (BIA) and handgrip strength.  相似文献

The Centers for Disease Control and Prevention report that among older adults (≥65 years), falls are the leading cause of injury‐related death. Fall‐related fractures among older women are more than twice as frequent as those for men. Gender‐specific evidence‐based fall prevention strategy and intervention studies show that improved patient‐centered outcomes are elusive. There is a paucity of emergency medicine literature on the topic. As part of the 2014 Academic Emergency Medicine (AEM) consensus conference on “Gender‐Specific Research in Emergency Care: Investigate, Understand, and Translate How Gender Affects Patient Outcomes,” a breakout group convened to generate a research agenda on priority questions to be answered on this topic. The consensus‐based priority research agenda is presented in this article.  相似文献

The purpose of this study was to determine a profile for predicting attrition among older adults involved in a 12-month exercise program. The parent study was a single-blinded randomized controlled trial. The study took place between 2006 and 2009 within a university setting. Older adults (N?=?179) completed baseline assessments of functional performance and psychosocial measures. Participants who were randomized, elected to receive treatment, and did not complete the exercise program were considered “dropouts” (n?=?35). Those who completed the program (n?=?144) were classified as “completers.” A latent profile analysis revealed two distinct patterns of memory complaints, self-efficacy to overcome barriers to exercise, balance performance, and stair performance. Dropouts were nearly twice as likely to be members of the profile that exhibited a higher degree of memory complaints, lower self-efficacy for overcoming exercise barriers, poorer single leg balance, and longer times to walk down stairs. The results provide an initial validation of a profile for discriminating between “dropouts” and “completers,” one that may have considerable utility for screening older adults prior to study entry.  相似文献
