This study investigated the effects of glutamine (Gln) on plasma intracellular adhesion molecule-1 levels and leukocyte integrin (CD11a/CD18 and CD11b/CD18) expressions in gut-derived sepsis. Myeloperoxidase (MPO) activities in organs were also analyzed to identify the extent of tissue injury resulting from neutrophil infiltration. ⋯ Results of this study demonstrate that a Gln-supplemented enteral diet increased lymphocyte CD11a/CD18 expressions, whereas neutrophil CD11b/CD18 expressions, circulating intracellular adhesion molecule-1 levels, and MPO activities in various organs decreased with gut-derived sepsis. These findings suggest that, under septic conditions, Gln administration may enhance lymphocyte function, attenuate interactions between polymorphonuclear lymphocytes and endothelium, and thus may decrease neutrophil infiltration into tissues.

Protein-energy malnutrition is common among infants with congenital heart disease. We hypothesized that infants with hypoplastic left heart syndrome (HLHS) are at risk for malnutrition. ⋯ Malnutrition is common in infants with HLHS after stage 1 palliation. Variables associated with more complex postoperative course and imbalance between systemic and pulmonary blood flow were all associated with poorer nutritional status. When adjusting for these factors, the use of parenteral nutrition and high calorie enteral feeds were associated with improved nutritional status. Aggressive parenteral and enteral nutritional therapy might help reduce the prevalence of growth faltering in infants who have HLHS.

Comparative Study
Impact of a computerized information system on quality of nutritional support in the ICU.
In intensive care units (ICUs), patient outcome depends on quality of nutritional support. We investigated the effect of computerized information systems (CISs) on quality of nutritional support by comparing two ICUs with or without CIS and burned patients before and after CIS implementation. ⋯ Computerized information systems favored standardization of nutritional care and monitoring, thus decreasing time required for writing and computations. Follow-up was improved and nutrient delivery was closer to target values, thus increasing quality of care. In burn patients, the better data visibility was associated with a significant improvement in nutrient delivery.

We describe the case of a 2-mo-old infant who weighed 3.5 kg, had alveolar interstitial pneumopathy on mechanical ventilation, and developed a duodenal perforation due to a 6-Fr polyurethane transpyloric tube. ⋯ If there is a clinical suspicion of intestinal perforation secondary to insertion of a transpyloric tube, the position of the tube must be confirmed by radiographic and echographic techniques. In case of doubt, the tube should be withdrawn and endoscopic or contrast radiographic evaluation must be performed.

Randomized Controlled Trial
Vitamin E and C supplementation prevents decrease of eicosapentaenoic acid in mononuclear cells in chronic hepatitis C patients during combination therapy of interferon alpha-2b and ribavirin.
We investigated the effects of vitamin E and C supplementation on the fatty acid composition of mononuclear cells and on the clinical observations in patients who had chronic hepatitis C and received interferon-alpha-2b (IFN-alpha-2b) and ribavirin combination therapy. ⋯ Antioxidant vitamin supplementation during IFN-alpha-2b and ribavirin therapy prevented a decrease in EPA of mononuclear cell phospholipids. If a further decrease in the ratio of arachidonic acid to EPA can be achieved by using oral EPA supplementation, the efficacy of IFN-alpha-2b and ribavirin therapy may be improved.
