RESISTÊNCIA AERÓBIA MUSCULAR PERIFÉRICA E CAPACIDADE FUNCIONAL EM IDOSOS COM DOENÇA PULMONAR OBSTRUTIVA CRÔNICA

The objective was to evaluate the peripheral muscular aerobic resistance of elderly people with Chronic Obstructive Pulmonary Disease (COPD) and to correlate it with the functional capacity. Anthropometric and clinical data, functional capacity and peripheral muscular aerobic resistance were evaluated, setting p≤ 0.05. The sample consisted of 14 individuals with COPD, presented London Chest Activity of Daily Living (LCADL) with impairment rates, 6-minute walk test (6MWT) within the normal range, TGlittre score below the reference values. 6MWT and TGlittre did not present a significant correlation with the performance time or the number of repetitions of the PPT. The evaluation of peripheral muscular resistance through the PPT was made difficult by the lack of reference values in the literature for the age group of the study population, however, a moderate significant correlation was found between the LCADL scale with the number of repetitions and the time of the PPT.El objetivo fue evaluar la resistencia aeróbica muscular periférica de ancianos con Enfermedad Pulmonar Obstructiva Crónica (EPOC) y correlacionarla con la capacidad funcional. Se evaluaron datos antropométricos, clínicos, capacidad funcional y resistencia aeróbica muscular periférica, fijándose una p≤ 0,05. La muestra estuvo compuesta por 14 personas con EPOC, presentaban London Chest Activity of Daily Living (LCADL) con tasas de deterioro, prueba de caminata de 6 minutos (6MWT) dentro del rango normal, puntaje TGlittre por debajo de los valores de referencia. 6MWT y TGlittre no presentaron una correlación significativa con el tiempo de ejecución o el número de repeticiones del PPT. La evaluación de la resistencia muscular periférica a través de la PPT se vio dificultada por la falta de valores de referencia en la literatura para el grupo etario de la población de estudio, sin embargo, se encontró una correlación significativa moderada entre la escala LCADL con el número de repeticiones y la hora del PPT.Objetivou-se avaliar a resistência aeróbia muscular periférica de idosos com Doença Pulmonar Obstrutiva Crônica (DPOC) e correlacionar com a capacidade funcional. Foram avaliados dados antropométricos e clínicos, capacidade funcional e resistência aeróbia muscular periférica, fixando-se o p≤ 0,05. A amostra foi composta por 14 indivíduos com DPOC, apresentaram London Chest Activity of Daily Living (LCADL) com índices de comprometimento, Teste de Caminhada de 6 minutos (TC6min) dentro da normalidade, escore de TGlittre abaixo dos valores de referência. TC6min e o TGlittre não apresentaram correlação significativa com o tempo de realização ou a quantidade de repetições do TPP. A avaliação da resistência muscular periférica através do TPP foi dificultada por não haver na literatura valores de referência para a faixa etária da população do estudo, porém foi encontrada uma correlação significativa moderada entre a escala LCADL com o número de repetições e o tempo do TPP

Static balance in older adults with chronic obstructive pulmonary disease undergoing pulmonary rehabilitation

OBJECTIVE: To compare balance between older adults with and without chronic obstructive pulmonary disease (COPD) in tasks involving proprioceptive changes and respiratory muscle load, and to investigate the association between balance, functional capacity, and peripheral and respiratory muscle strength. METHODS: Fourteen older adults with COPD undergoing pulmonary rehabilitation and nine older adults without pulmonary disease were evaluated for static balance on a force platform under four conditions: eyes open, eyes closed, eyes closed on foam, and eyes open with respiratory overload. Differences between groups, among conditions and group/condition interactions, were tested using two-way ANOVA. Associations were explored using Pearsons correlation coefficient. RESULTS: No differences in the posturographic variables were found in the group/condition interactions (p &ge;0.23). The COPD group exhibited greater total displacement (F = 8.79, p = 0.003), mediolateral sway (F = 4.01, p = 0.04) and anteroposterior velocity (F = 4.28, p = 0.04) in the group effect analysis. Significant differences were found between eyes closed on foam and other conditions for all posturographic variables: anteroposterior sway (F = 13.39), mediolateral sway (F = 28.58), total displacement (F = 59.4), area (F = 37.68), anteroposterior velocity (F = 26.42), and mediolateral velocity (F = 33.29), in the condition effect analysis (p &lt;0.001, post-hoc). In the COPD group, significant correlations were found between the Glittre-ADL test, anteroposterior sway (r = 0.68, p = 0.01), and anteroposterior velocity (r = 0.67, p = 0.009); the 6MWT was also correlated with anteroposterior velocity (r = 0.59, p = 0.03). CONCLUSION: Older adults with COPD present balance deficits compared to healthy individuals. The unstable surface caused greater postural instability compared to other conditions in both groups. Impaired balance was associated with reduced physical function and exercise capacity.</p

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
