Níveis de fósforo disponível e tamanho de partícula do fosfato bicálcico na dieta de poedeiras comerciais de 24 a 58 semanas de idade

Um experimento foi conduzido para verificar o efeito de níveis de fósforo e do tamanho de partícula do fosfato bicálcico na dieta de poedeiras comerciais na fase de produção. Utilizou-se um delineamento experimental inteiramente casualizado, em esquema fatorial 2 × 3 com dois tamanhos de partícula do fosfato (fino e granulado) e três níveis de fósforo disponível (0,28; 0,38 e 0,48%), totalizando seis tratamentos, cada um com cinco repetições de oito aves. As dietas experimentais foram isoproteicas, isocalóricas e isocálcicas. O consumo de ração, a produção de ovos, a massa de ovos, a conversão alimentar, a porcentagem de casca, a gravidade específica e os teores de cinzas, cálcio, fósforo e magnésio nos ossos não foram afetados pelas dietas. Dietas contendo fosfato bicálcico (fino ou granulado) e 0,28% de fósforo disponível atendem às exigências de fósforo de galinhas poedeiras semipesadas de 24 a 58 semanas de idade.

Cardiovascular fitness and cardiovascular risk factors among obese men and women aged 58 years and older, in Portugal

Background: A better physical fitness may have survival advantages in adults. Aim: To analyze the relationship between cardiorespiratory fitness and cardiovascular risk factors among obese subjects aged 58 years and older. Material and Methods: Cardiorespiratory fitness using the six-minute walk test, body composition by dual-energy x-ray absorptiometry and blood pressure were measured in a non-representative sample of 76 obese Portuguese subjects aged 58 to 87 years (55 women). Participants were stratified in tertiles of walking capacity according to the six-minute walk test. Results: Six minutes walk test results were negatively correlated with percentage body fat (r = -0.28; p = 0.012) and systolic blood pressure (r = -0.23; p = 0.045). Participants located in the lowest tertile for the six minutes walk test had an odds ratio of 4.34 (95% confidence intervals: 1.02-18.43) for elevated blood pressure. Conclusions: A lower six minutes walk test result is associated with a higher risk for high blood pressure. (Rev Med Chile 2012; 140: 1164-1169).

Paracoccidioidomicose: estudo radiológico e pulmonar de 58 casos

Spirometric and haemogasimetric tests were performed in 52 patients with unifocal and multifocal progressive Paracoccidioidomycosis pulmonary diseases, in 5 patients with juvenile and 1 female internal genital forms. The age ranged from 20 to 74 years old and the duration of disease from 3 to 25 years. Dyspnea, cough, tegumentary and lymphatic manifestations were the most predominant signs observed. Fourteen of them was developed Cor pulmonale. Impaired renal function was recorded in 19 patients, cardiac symptoms were described in 7 and hyporeactor adrenal activity was showed in 13 patients. Radiological studies demonstrated mild in 16, moderate in 24 and severe pulmonary lesions types in 18 patients. The pulmonary function revealed: normal spyrographic findings in 17, pure obstructive type in 32 and mixed form in 9 of them. Hyperventilation was described in 54 individuals and all of them showed an increasing of the alveolo-arterial difference. PaO2 less than 80 mm/Hg observed in 36 of them. Statistical analysis demonstrated significative association between clinical evolution and radiological interpretation. Similar data were obtained in radiology evaluations, clinical evolutive studies and pulmonary functions described in these patients. The granulomatous reaction due to Paracoccidioidomycosis, in heavy smokers patients, gave origin to the alterations in small airways predisposing the interalveolar dissemination an impaired alveolo-arterial diffusion.
