    ABSTRACT: A retrospective study using anthropometric data to assess the evolution of nutritional status in lung transplant candidates who are initially malnourished or overweight. We included patients with an initial body mass index (BMI) < 17 kg/m(2) (malnourished, n = 10) or > 27 kg/m(2) (overweight, n = 20). Each patient subsequently had three appointments with a nutritionist (nutritional interventions). In the malnourished group, there were no significant post-intervention changes in the anthropometric variables. In the overweight group, however, nutritional intervention had a positive impact on weight, BMI and waist circumference.

    ABSTRACT: Increased knowledge about nutritional status and energy and nutrient intakes is required to improve the treatment of patients with heart failure (HF). To verify the nutritional status and evaluate the adequacy of energy, macronutrient and micronutrient intakes in patients with HF in outpatient clinical settings. We collected anthropometric and habitual dietary intake data of 125 patients (72% men, 52.1 +/- 9.8 years, BMI 26.9 +/- 4.4 kg/m2). Anthropometric variables were compared between genders, and the adequacy of energy and nutrient intakes was analyzed according to current recommendations. Muscle depletion or risk of depletion was present in 38.4% of patients (association with male gender, p <0.0001). In 69.6% of cases the mean energy intake was lower than the one required (p <0.0001). Among the micronutrients evaluated in this study, there was an important prevalence of inadequacy in magnesium, zinc, iron and thiamine intakes, and most patients had calcium and potassium intakes below the adequate levels, and sodium intake above the adequate levels. Outpatients with HF showed muscle depletion, and inadequate energy and nutrient intakes. There was no significant association between habitual dietary energy intake and nutritional status. Multidisciplinary care should be encouraged to better assess the general condition of these patients.

    ABSTRACT: To determine the nutritional profile of lung transplant candidates. A retrospective cross-sectional study involving lung transplant candidates at a public hospital in the city of São Paulo, Brazil. Data related to gender, age and underlying lung disease were compiled for the participants. For the assessment of the nutritional profile of the patients, body mass index (BMI), mid-arm muscle circumference (MAMC), waist circumference and triceps skinfold thickness (TST) were determined during the first outpatient visit. We included 117 patients, 69 of which (59%) were male. The mean age of the participants was 42.5 +/- 15.2 years. The most prevalent underlying disease, seen in 29 patients (24.8%), was pulmonary emphysema. The nutritional profile was considered normal in 48.3% of the patients with pulmonary emphysema, 55% of those with cystic fibrosis, 56% of those with bronchiectasis and 50% of those with other lung diseases. The majority (51.7%) of the patients with pulmonary fibrosis were classified as overweight. The TSTs indicated that the risk of depletion was highest (64.7%) among the patients with cystic fibrosis, followed by those with bronchiectasis (52.6%). Patients with pulmonary fibrosis presented the highest BMIs, although the corresponding TSTs and MAMCs were normal. Patients with cystic fibrosis and bronchiectasis presented the highest prevalence of nutritional depletion, based on TST and MAMC.
