BACKGROUND & AIMS Malnutrition is frequently observed in chronic and severe diseases and associated with impaired outcome. In Germany general data on prevalence and impact of hospital malnutrition are missing. METHODS Nutritional state was assessed by subjective global assessment (SGA) and by anthropometric measurements in 1,886 consecutively admitted(More)
This review focuses on the studies investigating the prognostic implications of disease-related malnutrition. Malnutrition is a common problem in patients with chronic or severe diseases. Prevalence of hospital malnutrition ranges between 20% and 50% depending on the criteria used in order to determine malnutrition and the patient's characteristics.(More)
BACKGROUND The bioelectrical phase angle has shown predictive potential in various diseases, but general cutoffs are lacking in the clinical setting. OBJECTIVES This study evaluated the prognostic value of the fifth percentile of sex-, age-, and body mass index-stratified phase angle reference values in patients with cancer with respect to nutritional and(More)
OBJECTIVE Adipokines are fat-derived hormones and cytokines with immune-modulating and metabolic properties. Most of them are associated with insulin resistance. The aim of the present investigation was to evaluate circulating levels of adipokines and glucose homeostasis in patients with inflammatory bowel disease (IBD) and to evaluate possible associations(More)
BACKGROUND & AIMS Decreased functionality and muscle weakness are prominent features in cancer patients. We investigated determinants of muscle function assessed by hand grip and knee extension strength as well as functional status in cancer patients. METHODS 189 consecutively admitted cancer patients (age 60.8 ± 12.7 years, 96 male) were recruited.(More)
BACKGROUND & AIMS The use of phase angle (PhA) and raw parameters of bioelectrical impedance analysis (BIA) has gained attention as alternative to conventional error-prone calculation of body composition in disease. This review investigates the clinical relevance and applicability of PhA and Bioelectrical Impedance Vector Analysis (BIVA) which uses the plot(More)
BACKGROUND & AIMS Among all muscle function tests, measurement of hand grip strength has gained attention as a simple, non-invasive marker of muscle strength of upper extremities, well suitable for clinical use. This review outlines the prognostic relevance of grip strength in various clinical and epidemiologic settings and investigates its suitability as(More)
Phase angle (PhA), a parameter of bioelectrical impedance analysis, is a well-known predictor of morbidity and mortality in various diseases. The causes of decreased PhA are, however, not yet completely understood. We therefore investigated determinants of PhA in 777 hospitalised patients in a retrospective analysis. PhA was assessed by bioelectrical(More)
BACKGROUND Malnutrition is a common problem in patients with digestive disease and is associated with impaired outcome. OBJECTIVE We investigated the effect of a three-month post-hospital nutritional intervention with high protein and energy supplements on body composition, muscle function and quality of life (QoL) in malnourished GI patients. PATIENTS(More)
Malnutrition and depression are highly prevalent in the institutionalised elderly and can lead to unfavourable outcomes. The aim of the present study was to assess associations between nutritional status and depressive symptoms and to explore their impact on self-caring capacity and quality of life (QoL) in elderly nursing-home residents (NHR). We conducted(More)
