BACKGROUND & AIMS A system for screening of nutritional risk is described. It is based on the concept that nutritional support is indicated in patients who are severely ill with increased nutritional requirements, or who are severely undernourished, or who have certain degrees of severity of disease in combination with certain degrees of undernutrition.(More)
Fructans are naturally occurring plant oligosaccharides with sweetening properties. Fructans (FAs) isolated from Jerusalem artichokes (Helianthus tuberosus) were studied with respect to intestinal handling and influence on blood glucose (BG), insulin, and C-peptide responses in eight healthy subjects. The responses were compared with those for fructose(More)
We investigated the inhibitory effect of insulin and glucose on hepatic amino- to urea-nitrogen conversion independent of endogenous insulin and glucagon secretion. Alanine-stimulated urea synthesis kinetics, as quantified by functional hepatic nitrogen clearance, i.e. the slope of the linear relation between blood alpha-amino nitrogen concentration and(More)
Patients with cirrhosis of the liver often complain of tiredness and a lack of strength at physical exercise. Other investigators have found that muscle strength, work capacity, and maximal oxygen consumption are reduced in cirrhosis. We hypothesized that mitochondrial maximal rate of ATP synthesis in skeletal muscle may be impaired in these patients. This(More)
Lactulose H2 breath tests are widely used for quantifying carbohydrate malabsorption, but the validity of the commonly used technique (interval sampling of H2 concentrations) has not been systematically investigated. In eight healthy adults we studied the reproducibility of the technique and the accuracy with which 5 g and 20 g doses of lactulose could be(More)
BACKGROUND/METHODS Patients with active inflammatory bowel disease are often reported to be in negative nitrogen balance. Therefore, we examined basal and amino acid stimulated urea synthesis in 11 patients with active inflammatory bowel disease (six with Crohn's disease and five with ulcerative colitis) and in 10 patients with non-active disease (six with(More)
Malnutrition is common among patients with cirrhosis of the liver. During the last seven years a total of eight randomized studies concerning the effect of nutritional therapy on the clinical course of these patients have been published. In five of these trials nutritional therapy had an effect on the clinical course (reduced mortality, lessening of ascites(More)
We examined the effect of vitamin-K-rich vegetables, vitamin-K-poor vegetables and phytomenadione on the stability of warfarin-induced anticoagulation. Patients on stable anticoagulant treatment were randomized to either 1 (n = 5), 2 (n = 7) or 7 (n = 13) d with high intake of vitamin-K-rich vegetables (median daily vitamin K intake 1100 micrograms) or high(More)
Insulin-like growth factor (IGF)-binding protein-1 (IGFBP-1) normally circulates as a single, highly phosphorylated species. However, IGFBP-1 phosphorylation status can be altered, such as in pregnancy where non- and lesser phosphorylated isoforms are also present. We have examined how hormonal regulators of circulating IGFBP-1 influence its phosphorylation(More)
The aim of the present study was to determine whether changes in orocaecal transit time (OCTT) affect the magnitude of the breath hydrogen (H2) excretion after ingestion of unabsorbable carbohydrate. We studied eight healthy subjects by interval sampling of end expiratory H2 concentration for 12 hours after ingestion of: (1) 10 g lactulose (L); (2) 10 g L(More)
