One third of risk for dementia attributable to small vessel disease, autopsy study shows
Alzheimer's disease may be what most people fear as they grow older, but autopsy data from a long-range study of 3,400 men and women in the Seattle region found that the brains of a third of those who had become demented before death showed evidence of small vessel damage: the type of small, cumulative injury that can come from hypertension or diabetes.

Scientists identify new longevity genes
Scientists at the University of Washington and other institutions have identified 25 genes regulating lifespan in two organisms separated by about 1.5 billion years in evolutionary change. At least 15 of those genes have very similar versions in humans, suggesting that scientists may be able to target those genes to help slow down the aging process and treat age-related conditions. The study will be published online by the journal Genome Research on March 13.

Exercise testing may help predict seriousness of mitral regurgitation
NEW YORK (Dec. 11, 2007) -- In as many as one in five people over age 55, when the heart contracts to send blood around the body, some degree of backward leakage occurs across the mitral valve, a condition known as mitral regurgitation (MR). When sufficiently severe, MR causes buildup of blood in the lungs, leading to difficulty in breathing (dyspnea, or shortness of breath), a serious condition called congestive heart failure. MR also can cause heart rhythm irregularities (arrhythmias) such as atrial fibrillation, which can lead to strokes and other problems, and ventricular tachycardia, which can cause sudden death.

Aging with GRACE: Improving health care for older adults
INDIANAPOLIS - Most older adults obtain their health care in the offices of busy primary care physicians or, in the case of those without physicians, in even busier hospital emergency departments. In either location, seniors often don't receive the recommended care for preventive services, chronic disease management and geriatric syndromes. A study published in the December 12 issue of the Journal of the American Medical Association reports on GRACE, the largest randomized clinical trial of a health system and home-based geriatrics care concept designed to improve health care for community-dwelling low-income older adults.

Septic survival

These findings could help to improve the treatment of sepsis and improve survival rates further still.

Time and Money Constraints; other barriers hinder care for dementia
Built-in limitations of the health-care system in the United States, such as time and reimbursement constraints, inhibit the ability of primary care doctors to best meet the needs of dementia patients and their families, according to a new study by researchers at UC Davis Health System.
In a study now available in the online edition of the Journal of the Society of General Internal Medicine, the researchers found that physicians often feel challenged in caring for dementia patients, especially those who are more behaviorally complex. Constraints that are intrinsic to the contemporary practice of medicine may lead to the delayed detection of behavioral problems, a reactive as opposed to proactive management of dementia, and an increased reliance on treatment with drugs instead of psychosocial approaches.

New telomere discovery could help explain why cancer cells never stop dividing

This discovery, published online October 4 in Science Express, calls into question our understanding of how telomeres function, and may provide a new avenue of attack for stopping telomere renewal in cancer cells.
