Effect of a light-darkness cycle on the body weight gain of preterm infants admitted to the neonatal intensive care unit.

The Continuous bright light conditions to which premature infants are subjected while hospitalized in Neonatal Intensive Care Units (NICU) can have deleterious effects in terms of growth and development. This study evaluates the benefits of a light/darkness cycle (LDC) in weight and early hospital discharge from the NICU. Subjects were recruited from three participating institutions in Mexico.

Anthropometric variables and physical activity as predictors of cardiac cachexia.

Background: This study explored the frequency of cardiac cachexia in Mexican patients, the role of anthropometric variables as predictors of its development and its association with food intake and physical activity.

Methods: Seventy three patients with systolic heart failure were included in the study. Cardiac cachexia was defined as weight loss of >6.

Response to treatment during medium-term follow-up in a series of patients with neurocardiogenic syncope.

Background: Syncope is a common symptom that has different recurrence ratios. We hypothesized that an individualized treatment regimen including pharmacologic and nonpharmacologic measures considering kind of neurocardiogenic syncope (NCS) and basal characteristics of each patient could allow optimized therapy to avoid recurrences.

Methods: We conducted a prospective study to evaluate performance of diverse accepted treatments for NCS.
