Nutritional status, adiposity and asthma severity and control in children.

Aim: To investigate association between nutritional status, adiposity and asthma severity and control in children.

Methods: We conducted a case control study at two teaching hospitals in Brazil. Cases were children (3-12 years) with persistent asthma and age-matched controls were those with intermittent asthma.

Association between dietary habits and asthma severity in children.

Objective: To investigate association between dietary habits and asthma severity in children.

Design: Cross-sectional study.

Setting: Two teaching hospitals in Brazil.

Standardized phase angle from bioelectrical impedance analysis as prognostic factor for survival in patients with cancer.

Purpose: Phase angle (PA), determined by bioelectrical impedance analysis (BIA), has been considered as a prognostic factor in several clinical conditions. The purpose of this study is to investigate PA, after adjusting for sex and age (standardized phase angle; SPA) as a prognostic factor for survival in cancer patients.

Methods: A prospective study was conducted in 195 patients before the first chemotherapy course.

Body weight and fat-free mass changes in a cohort of patients receiving chemotherapy.

Purpose: Malnutrition is prevalent in cancer patients and it can become even greater during its treatment. The purpose of the present study is to verify changes in the fat-free mass (FFM) and body weight (BW) in cancer patients during chemotherapy treatment and to identify their significant determinants.

Methods: In a longitudinal study of 174 patients starting a chemotherapy protocol, bioelectrical impedance analysis (BIA) was used to estimate FFM and the nutritional assessment by patient-generated subjective global assessment.
