[Glycemic index and glycemic load in the Opuntia ficus-indica fruit].

Unlabelled: There is evidence that support the clinical usage of glycemic index (GI) and glycemic load (GL) in the prevention of chronic disease.

Objective: To determine the GI and GL of the Opuntia ficus-indica fruit.

Methodology: An analytic, transversal study was made involving 25 healthy volunteers accepted by an informed consent with a normal body mass index, glucose, glycoside hemoglobin, cholesterol and serum triglycerides.

Malnutrition risk factors among the elderly from the US-Mexico border: the "one thousand" study.

Background: The Mexican population is aging, which makes the fact that there is no regional information on the health of the elderly, including those in the northern region of the country.

Objective: To examine nutritional, functional, and cognitive impairments, as well as depression, in non-institutionalized elderly Mexicans along Mexico's northern border.

[Nutritional indicators in children with acute lymphoblastic leukemia].

Background: A nutritional assessment allows to determine the state of nutrition and to predict the possibility of displaying additional risks for a disease. Previous investigations have verified that it is not sufficient for children with acute lymphoblastic leukemia (ALL) to have registry of anthropometric measurements such as age, weight, and height. Given the previous information, it is necessary to conduct studies with nutritional indicators that contribute to understanding their importance in children with ALL.

Total homocysteine levels in healthy children from the Monterrey metropolitan area, Mexico.

Currently, there are indications for determining hyperhomocysteinemia in adulthood as risk factors for cardiovascular diseases, psychiatric disorders, pregnancy complications, birth defects, cognitive impairment in the elderly, in addition to cancer. If hyperhomocysteinemia is determined from childhood, it may be modulated with the provision of an opportunity for public health intervention. The objective of this descriptive study was to determine total homocysteine (tHcy) levels in healthy children from the Monterrey metropolitan area in Mexico.
