    Institutionalized elderly have an increased risk of changes in nutritional status, therefore sensitive parameters are necessary for the identification of changes in nutritional status. The aim of this study was to evaluate parameters for analysis of the nutritional status of institutionalized elderly in a period of three months by means of biochemical and anthropometric measurements. Eighty one volunteers were selected, with 78 ± 10 years old and 53% female. Anthropometric data showed that the variables body mass index, weight, fat mass, and phase angle of the institutionalized elderly in three months decreased with significant difference between the assessments. Among all the biochemical and anthropometric measurements, body mass index, weight, fat mass, phase angle and blood fat were the indicators of nutritional assessment that identified early changes and nutritional risks of institutionalized elderly in three months. It is noteworthy that the early evaluation of nutritional indicators can prevent nutritional risk among elderly in living in rest homes. Idosos institucionalizados apresentam um risco aumentado de alteração do estado nutricional. Sendo assim, são necessários indicadores sensíveis para identificação da alteração do estado nutricional. O objetivo deste estudo é avaliar indicadores para análise do estado nutricional de idosos institucionalizados, em um período de três meses, por meio de exames bioquímicos e antropométricos. Foram selecionados 81 voluntários, com 78 ± 10 anos, sendo 53% do sexo feminino. Os dados antropométricos evidenciaram que as variáveisíndice de massa corporal, peso, massa gorda e ângulo de fase dos idosos institucionalizados diminuíram em três meses com diferença significativa no período. Dentre todos os exames bioquímicos e antropométricos, as variáveis índice de massa corporal, peso, massa gorda, ângulo de fase e lipidograma foram os indicadores da avaliação nutricional que identificaram alterações precoces e riscos nutricionais dos idosos institucionalizados no período de três meses. Vale ressaltar que indicadores nutricionais avaliados precocemente podem evitar os riscos nutricionais de idosos institucionalizados.

    Metabolic changes in ruminant calves fed cation-anion diets with different proportions of roughage and concentrate
    (2012) Salles, Márcia Saladini Vieira; Zanetti, Marcus Antonio; Negrão, João Alberto; Salles, Fernando André; Ribeiro, Thiago Mauro Carvalho; Saran Netto, Arlindo; Del Claro, Gustavo Ribeiro
    Two experiments were carried out with twenty-four male weaned Holstein calves to verify the influence of different dietary cation-anion concentrate and roughage proportions on calves metabolism. In the first experiment, calves were fed rations with -100, +200 and +400 mEq cation-anion balance/kg of dry matter, containing 60% of roughage and 40% of concentrate. In the second experiment, calves (117.6±20.8 kg average weight) received rations with similar dietary cation-anion balance but in diets of 40% roughage and 60% concentrate. As the dietary cation-anion balance became more positive, there was a quadratic response of blood pH in both diets with 60 and 40% roughage. A linear increase following increased dietary cation-anion balance was observed on bicarbonate concentration, carbon dioxide tension, carbon dioxide partial pressure and urine pH on both experiments, while anion gap decreased linearly. Blood urea nitrogen and base excess increased quadratically according to increased dietary cation-anion balance on 60% roughage, whereas those same parameters showed a linear increase on 40% roughage. Growing ruminant metabolism both in cationic and anionic diets was modified when the roughage:concentrate ratio was altered.
