Nutritional supplementation according to energy and protein requirements in malnourished HIV-infected patients.

To evaluate the effects of nutritional supplements on nitrogen and energy balances, body composition and immune parameters, HIV-infected malnourished adult outpatients were prospectively studied. Forty-six patients (4 females and 42 males; 37 +/- 12 y) were supplemented with a polymeric diet (PD) or regular foods (RF) on two consecutive 45-day periods on a crossover design. Weight, skinfold thicknesses, plasma albumin (PA), CD4 and CD8 lymphocyte counts (LC), resting energy expenditure (REE) and urinary nitrogen excretion were measured at baseline, 45 and 90-day.

Inhibition of small intestinal motility by casein: a role of beta casomorphins?

Several aspects on the effect of nutrients on small intestinal motility are not completely understood. We have analyzed changes of motor activity of the canine small bowel following intragastric administration of casein and soy protein. Studies were performed by intraluminal manometry with external transducers and multiple infused catheters with closely spaced registrating sites.

[Anorexigenic drugs in the treatment of obesity].

Obesity is highly prevalent and has several adverse effects on health. Its treatment is thus warranted and must aim to modify dietary and physical activity habits. The opinion of this association is that anorexigenic drugs with cathecolaminergic action (diethylpropion, phentermine, mazindol and phenylpropanolamine) or serotoninergic action (fenfluoramine and fluoxetine) may be used in moderate or severe obesity (BMI > 30 kg/m2) after a complete clinical assessment and in the context of an integral medical treatment.

[Total parenteral nutrition in severe hyperemesis gravidarum].

Eight patients with severe HG, were treated through parenteral nutrition. This treatment was formulated as aminoacid, sucrose solution and fat solution (3 of 8 cases), blended with vitamins electrolites and oligoelements. The procedure lasted 5 at 16 days conforming a total of 77 days.
