We investigated the energy requirements of non-ambulatory patients with severe neurodevelopmental disabilities and chronic hypothermia. ⋯ Measured energy expenditure when the patient is normothermic significantly overestimated actual caloric needs. The energy intake necessary to achieve desired weight changes are restrictive when compared with the basal energy expenditure, Arlington Developmental Center equation, or measured energy expenditure when normothermic.

Studies on duodenal juice enzyme activities were carried out on suckling Wistar rats born to dams given ethanol during gestation and suckling. The results were compared with offspring of dams given diets containing no ethanol. Comparisons were also made with offspring of dams given ethanol and folic acid supplementation to observe whether a folate supplement could sufficiently reverse the negative effect of ethanol consumption. ⋯ Our findings indicated that, under basal conditions, ethanol treatment during gestation and lactation negatively affects the digestive function in offspring. The effects of ethanol were slightly attenuated in rats supplemented with folic acid for amylase activities. Although extrapolation from animal studies can be tenuous, the present findings may explain the use of folic acid in the prevention of damage induced by ethanol to increase the amylase levels to physiologic concentrations.

Because dietary fat composition is determinant for serum cholesterol level, which is related to cardiovascular disease, we evaluated the effects of diets containing saturated (coconut oil) or polyunsaturated fatty acids (soybean oil) supplemented or not with dietary cholesterol on serum and liver lipid composition in two animal species. ⋯ The type of experimental animal model and the diet composition influence lipid metabolism.
