We determined the nutrition status and prevalence of malnutrition as determined by the Subjective Global Assessment in Latin America, investigated the awareness of the health team with regard to nutrition status, evaluated the use of nutritional therapy, and assessed the governmental policies regulating the practice of nutritional therapy in each country. ⋯ Hospital malnutrition in Latin America is highly prevalent. Despite this prevalence, physicians' awareness of malnutrition is weak, nutritional therapy is not used routinely, and governmental policies for nutritional therapy are scarce.

Randomized Controlled Trial Clinical Trial
Soluble tumor necrosis factor-alpha receptor type 1 during selenium supplementation in psoriasis patients.
Tumor necrosis factor-alpha (TNF-alpha) and its receptors play important roles in the induction and maintenance of psoriatic lesions. Selenium (Se), a trace element with immunomodulatory properties, is usually decreased in psoriasis patients. We examined the influence of Se supplementation on soluble TNF-alpha receptor type 1 (sTNF-R1) and topical treatment in psoriasis patients. ⋯ Increased level of sTNF-R1 may be an indicator of active psoriasis. Supplementation with selenomethionine was ineffective as adjuvant treatment in plaque psoriasis and may contribute to the maintenance of elevated TNF-R1 concentration in psoriasis patients despite the remission of skin lesions.

Randomized Controlled Trial Clinical Trial
Plasma total homocysteine in Mexican rural and urban women fed typical model diets.
The purpose of the present work was to determine the fasting plasma total homocysteine (tHcy) levels and the time-course response of tHcy concentrations after the consumption of urban and rural Mexican model diets in two groups of Mexican women from urban and rural areas. ⋯ Plasma tHcy concentrations in rural and urban Mexican women were within the range considered adequate; however, urban women showed significant higher concentrations than did rural women independently of the consumed diet and the plasma methionine concentration. These results indicated that there is no short-term variation in plasma tHcy due to the consumption of rural or urban diets.

The study assessed the adequacy of nutrition support in critically ill infants and children and identifies barriers impeding the delivery of estimated energy requirement (EER). ⋯ This study highlights the inadequacy of nutrition support in critically ill children in the PICU. Restriction of fluid intake was the main barrier to the delivery of adequate nutrition, particularly in infants undergoing cardiac surgery.
