Vitamin D, not iron, is the main nutrient deficiency in pre-school and school-aged children in Mexico City: a cross-sectional study.

Introduction: In 2012, the Mexican National Health Survey showed a moderate prevalence rate of vitamin D deficiency, around 16%, in a national representative sample of children. A decreasing prevalence of anemia during the last 15 years has been observed in Mexico. The aim of this study was to determine the levels of vitamin D in children 3-8 years old in four different locations within the metropolitan area of Mexico City and to compare them to levels of iron and zinc as references of nutritional status.

[Prevalence of kidney disease in asymptomatic children with family history of renal replacement therapy].

Background: Having a first- or second-degree relative with chronic kidney disease (CKD) has been reported as a risk factor for CKD development. The aim of the study was to determine the prevalence of CKD in children with a first- or second-degree relative undergoing renal replacement therapy (hemodialysis or renal transplant).

Methods: A screening study was performed in asymptomatic children with a family history of CKD in a first- or second-degree relative undergoing renal replacement therapy.

[Enteral nutrition in the preterm and term newborn with low birth weight].

Unlabelled: Nutritioinal practices vary dramatically among neonatal intensive care units (NICU) in other countries. In many hospitals, nutrition is introduced gradually over the first weeks of life because the risk of necrotizing enterocolitis or nutrient intolerance is considered inevitable. Enteral nutrition practices among premature and near term infants with low birth weight were investigated.

[Use of a preterm formula with long chain polyunsaturated fatty acids: acceptability and tolerance].

Introduction: The majority of preterm formulas have included long chain polyunsaturated fatty acids (LCPUFAS) for the relationship with visual and cognoscitive brain development. This work tried to probe the tolerance and acceptability of a preterm formula from the point of view of palatability for the LCPUFAs origin.

Methods: Infants under 37 weeks of gestational age at birth and birth weight below 2,500g with the possibility of being fed by suction and not receiving breast milk were included.
