Randomized Controlled Trial Comparative Study Clinical TrialA comparison of two 20% lipid emulsions.
Two different soy oil emulsions (Intralipid and Soyacal) were studied over a 2-week period in a random crossover study to determine if there were clinical or biochemical differences between the two preparations when used in patients requiring total parenteral nutrition (TPN). Each fat emulsion was infused randomly over 1 week and then switched to the other. Eighteen adult patients requiring a minimum of 14 days TPN were studied. ⋯ Analysis of nutritional status, irrespective of lipid infused, showed that the patients who received 56 kcal/kg/day with 37% of the nonprotein calories from lipids (1.8 +/- 0.7 g/kcal/day) were in positive nitrogen balance on 80 of the 101 days studied. No adverse effects could be observed from either lipid emulsion during the short period of TPN used in this study. Both lipid emulsions were efficacious as a caloric source, and no clinical complications or biochemical abnormalities were found from either preparation.

Randomized Controlled Trial Clinical TrialEffect of guar gum added to the diet of patients with duodenal ulcer.
In a randomized, double-blind, controlled clinical study, the effects of 5 g of guar gum, a dietary fiber composed of galactose and mannose, or placebo added to the diet of 20 patients with duodenal ulcer for 1 wk each were examined. Ten patients derived evident benefit and five some help from guar gum, on comparing symptoms during administration of guar gum with those experienced earlier or during the placebo week, whereas four patients found that neither guar gum nor placebo had any effect (p less than 0.001). The beneficial effect was associated with increased feelings of repletion after meals. ⋯ The diarrhea which occurs in some patients ingesting guar gum was avoided by giving low initial doses. In three patients unpalatability of guar gum was a minor complaint. It is concluded that guar gum is helpful to many patients with uncomplicated duodenal ulcer, but that it is harmful to those having increased gastric emptying, eg, pyloric stenosis patients, and that guar gum may exert its effects by increasing gastric emptying time.
