Houston, Tex. – November 18, 2008 – A study appearing in Journal of the American Geriatrics Society shows that Medicare beneficiaries' understanding of their healthcare benefits may affect their ability to access needed care effectively and could lead them to the delay or avoid seeking care.

With millions of baby boomers entering late adulthood, the number of patients with Alzheimer's disease (AD) is expected to drastically rise over the next several decades.
A team of national researchers, led by Emory University, has developed a rapid screening test to detect mild cognitive impairment (MCI) — often the earliest stage of AD. The findings are published today in the online edition of Journal of Alzheimer's Disease.
WASHINGTON, D.C. - Scientists at the University of Texas at Austin have identified pathways by which a reduced-calorie diet and exercise can modify a postmenopausal woman's risk of breast cancer.
WASHINGTON, D.C. - The cancer preventive properties of broccoli and other cruciferous vegetables appear to work specifically in smokers, according to data presented at the American Association for Cancer Research's Seventh Annual International Conference on Frontiers in Cancer Prevention Research.
WASHINGTON, D.C. - Climbing stairs, carrying groceries, taking a shower – these are activities that we take for granted; however, after a cancer diagnosis, many survivors are unable to function as they used to. Home-based diet and exercise interventions may improve physical functioning in older, long-term cancer survivors, according to data presented at the American Association for Cancer Research's Seventh Annual International Conference on Frontiers in Cancer Prevention Research.
New York, NY, November 18, 2008 -- Researchers at the University of California, San Francisco have reported that two common cancer drugs have been used to block and reverse type 1 diabetes in mice. The JDRF-funded study, published in The Proceedings of the National Academy of Sciences, was led by Jeffrey Bluestone, Ph.D., director of the Diabetes Center at UCSF and an expert in the field of autoimmunity.
A nontoxic nanoparticle developed by Penn State researchers is proving to be an all-around effective delivery system for both therapeutic drugs and the fluorescent dyes that can track their delivery.
In a recent online issue of Nano Letters, an interdisciplinary group of materials scientists, chemists, bioengineers, physicists, and pharmacologists show that calcium phosphate particles ranging in size from 20 to 50 nanometers will successfully enter cells and dissolve harmlessly, releasing their cargo of drugs or dye.
Why are so many infectious diseases jumping from animals to humans? Why do we have so little capacity to predict epidemics, or avoid them? Some answers, and possible solutions, can be found in the first trench-to-bench guide to wild primate infectious diseases, published Nov. 17 in the Yearbook of Physical Anthropology.
Irvine, Calif., Nov. 18, 2008 — Raging wildfires that engulfed Southern California earlier this decade not only destroyed neighborhoods laying in their path, they also caused significant health problems for many who lived outside the fires' reach.
AMES, Iowa -- Friction is the bane of any machine. When moving parts are subject to friction, it takes more energy to move them, the machine doesn't operate as efficiently, and the parts have a tendency to wear out over time.
But if you could manufacture parts that had tough, "slippery" surfaces, there'd be less friction, requiring less input energy and the parts would last longer. Researchers at the U.S. Department of Energy's (DOE) Ames Laboratory are collaborating with other research labs, universities, and industrial partners to develop just such a coating.
ANN ARBOR, Mich. — Online support communities for high survival rate cancers contain a greater amount of emotional support content than online support communities for cancers with low survival rates, according to a new study from the University of Michigan Health System and the VA Ann Arbor Healthcare System.
The researchers also found that support communities for low survival rate cancers contain a greater amount of informational support content than online support communities for high survival rate cancers.
WASHINGTON, D.C. - The risk of non-AIDS cancer is higher for individuals infected with HIV than for the general population, according to a meta-analysis presented here at the American Association for Cancer Research's Seventh Annual International Conference on Frontiers in Cancer Prevention Research.
WASHINGTON, D.C. - An abstract presented at the American Association for Cancer Research's Seventh Annual International Conference on Frontiers in Cancer Prevention Research shows that lower socioeconomic status reduced the chance of early stage diagnosis and survival of colorectal cancer in Colorado.
WASHINGTON, D.C. - African-American women are at a higher risk for ER/PR negative breast cancer. A new study, to be presented at the American Association for Cancer Research's Seventh Annual International Conference on Frontiers in Cancer Prevention Research, found that race, socioeconomic characteristics and other tumor characteristics are all important predictors of having ER/PR negative breast cancer.
ER/PR negative breast cancer has a poorer prognosis than hormonally-responsive cancer because treatment options are more limited.
A new study provides the first evidence of a link between alcohol-industry sponsorship and hazardous drinking among sportspeople.
Researchers from The University of Manchester and the University of Newcastle in Australia quizzed nearly 1,300 sportspeople and found alcohol-related companies sponsored almost half of them.
The sponsorship ranged from financial incentives, such as payment of competition fees and the supply of sports kit, but nearly half of the sponsorship deals included free or discounted alcohol for sporting functions and post-match celebrations.
