Animal studies support a cancer-promoting role for fat, and in humans, epidemiological data strongly suggest that dietary fat intake may be associated with incidence and mortality of cancers of the breast, colon, rectum, and prostate. There are also data implicating fat in cancers of the ovaries, uterus, pancreas, and lung, but the evidence is not as strong. There is still a debate as to whether it is total dietary fat, specific fats, or total calories that are involved in carcinogenesis. In any event, cancers of breast, colon, and prostate are highest in North America and western Europe and lowest in Asia, and are directly related to the intake of total fat in the diet even when adjusted for total calories.

The proportion of elderly at any age without any chronic conditions is small, and disease can trigger a cascade of events resulting in functional deficits and disability. An increase in the number of activities with which an elder has difficulty increases linearly with comorbidity, that is, coexistent medical conditions that further complicate not only the genesis of a functional deficit but also its treatment. For example, rehabilitation for a stroke for an individual who also has painful, degenerative changes in the foot and a low tolerance for stressful activity secondary to angina with exertion would present a particular rehabilitation challenge. Yet, this example encapsulates geriatric rehabilitation specialist’s emphasis on care and function, not cure and disease. (more…)

Not all body fat is equally bad for your health. It is widely known that body fat distribution is extremely important. There is increasing evidence for the deleterious effects of Visceral Fat on aging. Waist-to-hip ratio (WHR) is an epidemiological tool that demonstrates a correlation between Visceral Fat and development of diabetes mellitus, stroke, coronary artery disease, and mortality. This ratio is easily determined by dividing the measurement of waist circumference by hip circumference. (more…)

Cancer occurrence rates in a period of time for a given population is expressed in various ways. The incidence rate is a direct measure of the probability of developing cancer and is usually expressed per year. Incidence rates may be crude (all ages) or age specific. Since cancer is very age dependent, age specific rates are usually more informative. Cancer in elderly is more prevalent compare to cancer in younger age. When comparing population groups with different age distributions (such as the United States vs. China), the incidence rate should be age adjusted by multiplying each age-specific rate by the percent of individuals in a population with the same ages and then summing these to produce a single value. For etiological studies, incidence rates tend to be more informative than mortality rates, as they identify all diagnosed cases. (more…)

The regulation of fluid balance is crucial to survival. Approximately 9 L of fluid enters the gastrointestinal tract per day. Of that amount, about 2 L is ingested by mouth. The remaining 7 L consists of fluids secreted by the various gastrointestinal organs. Ninety eight percent of the total amount of fluid that enters the gastrointestinal tract is reabsorbed in the small intestine and the colon. (more…)

Mutations that extend lifespan in invertebrates typically render the animals resistant to multiple forms of lethal injury, whether the threat comes from oxidative agents, heat, heavy metals, or irradiation. Indeed, this stress resistance seems likely to represent the mechanism by which these mutations delay the aging process. Thus presumably much of the cellular and extracellular pathology that produces dysfunction and increases mortality risk in older animals is held in abeyance by the same, poorly defined, defenses that permit nematodes and flies to survive when exposed to external stress in an experimental setting.

First the blood vessels. The walls of the arteries stiffen with age. And the largest blood vessel in the body, the aorta, gets longer and dilates as you get older. These developments can occur just from aging and in the absence of significant atherosclerosis in the vessels. They are secondary to changes that are happening to collagen and elastin and to deposits of calcium. The actual tonus (or tension) of the arteries also increases with the progressive thickening of the layer of the arterial wall that is present under the inside lining. These changes may contribute to high blood pressure and damage to the arteries, which encourage atherosclerosis. (more…)
