Gastric emptying is determined by food consistency, pH, osmolality, lipid and calorie content as well as the presence of different nutrients in the duodenal lumen. Control of gastric emptying is essential for ensuring optimal digestion. The present study tested the hypothesis that due to its different precipitation properties, gastric emptying of camel's milk may be quicker than that of bovine's milk with the same caloric and fat content. ⋯ Camel's milk is most probably not a useful substitute for other types of milk to shorten gastric emptying.

Randomized Controlled Trial
Metabolic effects of parenteral nutrition enriched with n-3 polyunsaturated fatty acids in critically ill patients.
n-3 fatty acids are expected to downregulate the inflammatory responses, and hence may decrease insulin resistance. On the other hand, n-3 fatty acid supplementation has been reported to increase glycemia in type 2 diabetes. We therefore assessed the effect of n-3 fatty acids delivered with parenteral nutrition on glucose metabolism in surgical intensive care patients. ⋯ n-3 fatty acids were well tolerated in this group of severely ill patients. They decreased total energy expenditure without adverse metabolic effects.

Comparative Study
Comparison of tools for nutritional assessment and screening at hospital admission: a population study.
This population study aimed to test the sensitivity and specificity of nutritional risk index (NRI), malnutrition universal screening tool (MUST) and nutritional risk screening tool 2002 (NRS-2002) compared to subjective global assessment (SGA) and to evaluate the association between nutritional risk determined by these screening tools and length of hospital stay (LOS). ⋯ NRS-2002 had higher sensitivity and specificity than the MUST and NRI, compared to SGA. There was a significant association between LOS and nutritional status and risk by SGA, NRS-2002, MUST and NRI. Nutritional status and risk can be assessed by SGA, NRS-2002 and MUST in patients at hospital admission.

Controlled Clinical Trial
Effects of polyphenolic antioxidants on exercise-induced oxidative stress.
Polyphenols are of increasing interest to consumers and food manufacturers for several reasons. Commonly referred to as antioxidants (they are the most abundant antioxidants in our diets), they may prevent various oxidative stress-related diseases, such as cancer, cardiovascular disease, inflammation and others. Physical activity is known to induce oxidative stress in individuals after intensive exercise. ⋯ However, in response to strenuous exercise, the polyphenol-supplemented test showed a smaller increase in plasma TBARS and CK than the placebo test. CO increased by 12% in response to the placebo test, whereas it decreased by 23% in the polyphenol-supplement test. This may indicate that the antioxidant supplement offered protection against exercise-induced oxidative stress.

Many barriers make implementation of nutritional therapy difficult in hospitals. In this study we investigated whether, a targeted plan made by the staff in different departments could improve nutritional treatment within selected quality goals based on the ESPEN screening guidelines. ⋯ The introduction of a new method for implementation of nutritional therapy according to ESPEN screening guidelines seems to improve nutritional therapy in hospitals. The method included assessment of quality goals, identification of barriers and individual targeted plans for each department followed by an evaluation process. The model has to be refined further with relevant clinical endpoints.
