Journal of Aging Research , 2012, DOI: 10.1155/2012/518045
Abstract: Low cardiorespiratory (CRF) is associated with health problems in elderly people, especially cardiovascular and metabolic disease. However, physical limitations in this population frequently preclude the application of aerobic tests. We developed a model to estimate CRF without aerobic testing in older men with chronic cardiovascular and metabolic diseases. Subjects aged from 60 to 91 years were randomly assigned into validation ( ?? = 6 7 ) and cross-validation ( ?? = 2 9 ) groups. A hierarchical linear regression model included age, self-reported fitness, and handgrip strength normalized to body weight ( ?? 2 = 0 . 7 9 ; SEE?=?1.1 METs). The PRESS (predicted residual sum of squares) statistics revealed minimal shrinkage in relation to the original model and that predicted by the model and actual CRF correlated well in the cross-validation group ( ?? = 0 . 8 5 ). The area under curve (AUC) values suggested a good accuracy of the model to detect disability in the validation (0.876, 95% CI: 0.793–0.959) and cross-validation groups (0.826, 95% CI: 0.677–0.975). Our findings suggest that CRF can be reliably estimated without exercise test in unhealthy elderly men. 1. Introduction Cardiorespiratory fitness (CRF) maintenance is important for functional independence and physical capacity throughout aging [1, 2]. Substantial declines in the ability to tolerate physical exertion generally predict mobility problems and cardiovascular morbidity and mortality, particularly in the sedentary elderly [3, 4]. Despite the importance of CRF assessment, very low functional capacity and frailty may hinder the use of exercise tests in this population [5, 6]. In this context, nonexercise prediction models become practical alternatives to estimate CRF [7] and may have important applications both in clinical and epidemiological settings. These models are developed by means of regression-based equations that usually include variables of simple and fast assessment, such as anthropometric measures, demographic characteristics, and daily habits [8]. Recently, Mailey et al. [7] cross-validated an equation developed primarily in middle-aged adults by Jurca et al. [9] and suggested that nonexercise models could be used to estimate the CRF of older adults. The sample studied was mainly composed by healthy old women (~60%). However, the prevalence of chronic diseases such as cardiovascular disease and diabetes increases dramatically with age [10], and is associated to lower physical capacity, inactivity, and limitations in the ability to exercise [2]. It would be therefore important

Revista Brasileira de Cirurgia Cardiovascular , 1998,
Abstract: Os autores apresentam 1 caso de hérnia intrapericárdica transdiafragmática, resultado de trauma contuso e fazem revis o de 37 casos similares. Os traumas, em 71,05%, foram conseqüentes a acidentes de transito, com veículos automotores. Os pacientes apresentaram sintomatologia tardia predominante do cora o e, também, queixa do aparelho digestivo. Contudo, a insuficiência cardíaca só foi comprovada duas vezes e os sintomas abdominais, na maioria dos casos, foram confirmados pelos sinais de tra o, de distens o ou de oclus o gastrointestinal. Com estudos radiográficos contrastados, o diagnóstico foi conclusivo em 28, 94% e houve suspeita de hérnia diafragmática em 55,26% dos casos. O tratamento cirúrgico foi empregado em todos os pacientes, havendo poucas complica es pós-operatórias e apenas 3 (7,89%) óbitos. A jun o entre o centro tendíneo diafragmático e o pericárdio basal foi o local comum das roturas em todos os casos e o colo transverso foi a víscera mais herniada. Em alguns casos, as roturas alcan aram as hemicúpulas diafragmáticas, permitindo hérnias também para os espa os pleurais. Hipóteses de existirem coincidentes pontos de enfraquecimento embrionário nas hemicúpulas diafragmáticas, de haver regi es anat micas centrais frenopericárdicas adelga adas e de ocorrer períodos latentes para as forma es herniárias, s o levantadas com as devidas argumenta es. Detalhes seletivos dos exames complementares s o apontados no intuito de facilitar o diagnóstico. S o realizadas análises sobre a abordagem cirúrgica empregada e apresentadas sugest es quanto ao uso da via abdominal ou torácica.

Abstract: background: the veterans specific activity questionnaire (vsaq) has been used to individualize exercise testing (et) and to indirectly assess cardiorespiratory fitness (crf) in epidemiological studies. nevertheless, there is no validated portuguese version. objective: to verify the criterion-related validity and the measurement equivalence of a portuguese version of vsaq in 95 individuals, 8 women (aged 69 ± 7 years) referred to et. methods: the subjects performed a cardiopulmonary test with incremental to maximal exercise on a cycle ergometer. the correlation between vsaq score and maximum measured and estimated mets was compared to results from other studies. the vsaq nomogram was calculated and its results were compared to crf real values by linear regression. limits of concordance and mean differences (biases) were assessed according to the bland altman methodology. results: the vsaq scores were significantly correlated to the measured mets (r = 0.64) and estimated mets (r = 0.67), results that were equivalent to those obtained by the original versions. the vsaq nomogram presented multiple r of 0.78 (measured met) and 0.80 (estimated met). however, the nomogram seems to have underestimated crf values greater than 6 mets. conclusion: the vsaq version confirmed its validity and equivalence to the original version, especially when evaluating individuals with coronary heart disease and older adults.

Abstract: this study aimed at establishing the cross-cultural equivalence of scales used to evaluate physical activity level and measure cardiorespiratory fitness, for further application in elderly subjects. three scales were identified after systematic review: veterans physical activity questionnaire (vsaq), rating of perceived capacity (rpc), and physical activity rating (pa-r). the model proposed by herdman et al. was applied to analyze equivalence. test-retest reliability was calculated in a sample of 12 elderly subjects (74.5 ± 3.5 years) using lin's concordance coefficient and intraclass correlation coefficient. good reproducibility was detected in all scales except rpc. due to the small sample size, hardly any conclusions can de drawn, but the results point to the need for changes in the original scale's structures. the findings also suggest the adequacy of the scale's portuguese-language version, although further validity studies appear to be necessary.

Acta Botanica Brasilica , 2004, DOI: 10.1590/S0102-33062004000400014
Abstract: a study was conducted in a riparian forest (rio paraguai, brazil) to verify the vegetation mortality after an exceptional flooding in 1995. individuals with diameter at breast height > 5 cm were sampled in 108 (10×10m) plots in 1994, and re-sampled in 1996. the total mortality rate was 4.1% per year. the mortality increased with the increasing of topographic positions, at community level, suggesting that places where the flooding is less frequent are more affected by extreme floods.
