Randomized Controlled Trial Clinical Trial
A prospective randomised trial of probiotics in critically ill patients.
Probiotics exert a beneficial effect on the host through modulation of gastrointestinal microflora. The aim of this study was to investigate the effect of the probiotic Lactobacillus plantarum 299v on gut barrier function and the systemic inflammatory response in critically ill patients. ⋯ The enteral administration of L. plantarum 299v to critically ill patients was associated with a late attenuation of the systemic inflammatory response. This was not accompanied by any significant changes in the intestinal microflora, intestinal permeability, endotoxin exposure, septic morbidity or mortality.

Nutrition and dietary patterns have been shown to have direct impact on health of the population and of selected patient groups. The beneficial effects have been attributed to the reduction of oxidative damage caused by the normal or excessive free radical production. The papers aims at collecting evidence of successful supplementation strategies. ⋯ Antioxidant micronutrients have beneficial effects in defined models and pathologies, in the general population and in critical illness: ongoing research encourages this supportive therapeutic approach. Further research is required to determined the optimal micronutrient combinations and the doses required according to timing of intervention.

Free amino acid and glutathione concentrations in muscle during short-term starvation and refeeding.
The effects of short-term starvation and refeeding on the free amino acids and glutathione in skeletal muscle in healthy man are not known. This is necessary baseline knowledge when studying the effects of nutrition, trauma and sepsis on protein, amino acid and glutathione metabolism. ⋯ A short-term fasting followed by a refeeding period induced changes in the concentrations of concentrations of glutamate, glutamine, branched chained and basic amino acids in muscle and plasma. Despite this, no changes were seen regarding the glutathione levels in muscle and plasma or its redox status, indicating that the glutathione system is of priority.
