abstract older people enconter a reduced balance performance as they have lower sensory and motor abilities. balance problem pomote the risk of falling and subsequent disabling injuries and even death among older people.these problems can impose an extensive chargers on healthcare systems. insole and footwear are an interface between plantar surface and the ground and can regulate the sensory i...

introduction: a challenge for health care providers is that there will be a distinct rise globally in the number of elderly people aged 80 years and over. malnutrition is a well-known problem among elderly people. the aim of this study was to determine nutritional status and its associated risk factors in elderly nursing home residents in tehran, iran. methods: the cross-sectional study was car...

tetanus can be only prevented by vaccination because immunity against this disease is rarely acquired, even by natural infections. to maintain long-term protective immunity against tetanus, booster immunization is essential for adolescents and adults. most hospitalized cases and virtually all deaths occur in people over 60 years of age. the purpose of this study was to investigate the degree of...

oxygen consumption (VO2), diminished with age. Older subjects had a lower resting cardiac output (Q) than normal subjects, but an identical increase in Q with Vo,. There was no evidence of flattening of this curve as the older subjects approached highest exercise loads. Consequently, the arteriovenous oxygen difference did not increase abnormally on high loads, and the cardiac response to exerc...

BACKGROUND Aging is associated with changes of the systolic blood pressure that may increase cardiac work and myocardial blood flow at rest and reduce the myocardial flow reserve. This might be misinterpreted as age-related impairment of the coronary vasodilator capacity. METHODS AND RESULTS Myocardial blood flow was quantified at rest and after administration of intravenous dipyridamole in 4...

We investigated the influence of aging on cardiac baroreflex function during dynamic exercise in seven young (22 +/- 1 yr) and eight older middle-aged (59 +/- 2 yr) healthy subjects. Carotid-cardiac baroreflex function was assessed at rest and during moderate-intensity steady-state cycling performed at 50% heart rate reserve (HRR). Five-second pulses of neck pressure and neck suction from +40 t...
