Randomized Controlled Trial Comparative Study Clinical Trial
A double-blind, randomized, controlled trial of the effects of two eggs per day in moderately hypercholesterolemic and combined hyperlipidemic subjects taught the NCEP step I diet.
We investigated the effect of egg feeding in 161 hypercholesterolemic (HC) or combined hyperlipidemic (CHL) free-living subjects taught the NCEP Step I Diet. ⋯ CHL subjects ingesting a Step I Diet in a free-living setting are sensitive to egg feeding and should benefit from dietary cholesterol restriction. The limited LDL-C rise in HC subjects resembles that seen in egg-fed normocholesterolemic subjects ingesting a Step I Diet, but requires confirmation.

Comparative Study
Transitions in infant feeding during the first year of life.
To document ages at which transitions in infant feeding occur, to compare these transitions to literature reports from the 1970s and 80s, and to identify maternal characteristics related to the age of the infant when solid food was first introduced. ⋯ The finding that the mothers' decision whether or not to breastfeed was made prior to conception supports the importance of population-based education aimed at women in the child-bearing years as well as patient instruction early in the pregnancy. However, the duration of breastfeeding was shorter than was reported in the 1980s. Infants varied greatly in ages when the seven categories of complementary foods were added to their diets. Although recommendations for delaying introduction of solid foods until the infant is 4 to 6 months of age have been in place for more than a decade, about half the mothers in this study did so earlier. Characteristics of mothers who introduced cereal earliest (i.e., mean age of infants < 4 months) were more likely to be formula feeding when cereal was added, to feed cereal via the bottle, to be primiparous, to be employed outside the home, and/or not to cite the physician as a source for guiding the infant's transition to supplemental food.

Comparative Study
Dose-dependent effect of octreotide on nitrogen retention and glucose homeostasis in response to endotoxemia in parenterally fed rats.
This study compared the effect of different doses of octreotide on glucose and protein homeostasis in rats receiving concomitant lipopolysaccharide and parenteral nutrition infusions. ⋯ Endotoxin significantly reduces nitrogen balance compared to controls fed PN. Octreotide does not significantly improve nitrogen retention or glucose homeostasis in endotoxemic parenterally fed rats.

The stomach stores food and starts digesting protein and fat. Lipids, sugars, certain amino acids, and nutrients of high osmolality trigger sensory mechanisms from the intestine which inhibit gastric emptying. Food rich in carbohydrates leaves the stomach slower than protein-rich food, and emptying is slowest after a meal containing lipid. ⋯ In healthy children ingesting different juices, the myoelectric pattern of the stomach (indicator of the gastric emptying) correlates with the carbohydrate absorption (measured by breath hydrogen excretion). Fast gastric emptying was associated with greater production of breath hydrogen. The malabsorption of juice carbohydrates may in part be related to their effect on gastric motility.
