Using machine learning classifiers to assist healthcare-related decisions: classification of electronic patient records.

Surveillance Levels (SLs) are categories for medical patients (used in Brazil) that represent different types of medical recommendations. SLs are defined according to risk factors and the medical and developmental history of patients. Each SL is associated with specific educational and clinical measures.

Impact of maternal vitamin A supplementation on the mother-infant pair in Brazil.

Background/objectives: Vitamin A deficiency (VAD) is a major public health problem. The supplementation of lactating women could be an effective strategy to combat it. The objective of this study was to assess the impact of maternal vitamin A supplementation on the mother-infant pair.

Is suppression of hypothalamic-pituitary-adrenal axis significant during clinical treatment of phimosis?

Purpose: Corticoids have been an option for phimosis treatment since 1993. However, long-term use or repeated cycles pose a concern regarding drug absorption and consequent systemic effects. The aim of this study was to investigate the effect of topical corticoids used in treating phimosis on the hypothalamus-pituitary-adrenal axis in children.

Can the insulin sensitivity index (ISI) in association with insulin-like growth factor binding protein-1 identify insulin resistance early in overweight children?

Unlabelled: Association between insulin resistance (IR) and non-alcoholic fatty liver disease (NAFLD) has been reported. This prompted us to evaluate the power of the insulin sensitivity index (ISI) in association with IGFBP-1 to identify IR early in obese children/adolescents. OGTT was performed in 34 obese/overweight children/adolescents.

Zinc serum levels and their association with vitamin A deficiency in preschool children.

Objectives: To identify the prevalence of zinc deficiency in a population with high prevalence of vitamin A deficiency; to verify whether zinc deficiency is associated with vitamin A deficiency in the population studied; to verify risk factors for zinc deficiency (sex, age, diarrhea and fever).

Method: Cross-sectional study of 182 healthy children aged > or = 24 months and < 72 months. Peripheral blood samples were obtained from fasting children to determine zinc serum levels.
