Hormone therapy may be hazardous for men with heart conditions (7/31/2011)

Adding hormone therapy to radiation therapy has been proven in randomized clinical trials to improve overall survival for men with intermediate- and high-risk prostate cancer. However, adding hormone therapy may reduce overall survival in men with pre-existing heart conditions, even if they have high-risk prostate cancer according to a new study just published online in advance of print in the International Journal of Radiation Oncology?Biology?Physics, the official scientific journal of ASTRO. ...> Full Article


Does menopause matter when it comes to diabetes? (7/30/2011)

Menopause has little to no impact on whether women become more susceptible to diabetes, according to a one-of-a-kind study that provides good news for older women. Postmenopausal women had no higher risk for diabetes whether they experienced natural menopause or had their ovaries removed, according to the national clinical trial of women, ages 40 to 65. ...> Full Article


Older people find it harder to see the wood for the trees (7/29/2011)

When looking at a picture of many trees, young people will tend to say: "This is a forest." However, the older we get, the more likely we are to notice a single tree before seeing the forest. In a new study published in the July-August issue of Elsevier's Cortex, researchers have found that these age-related changes are correlated with a specific aspect of visual perception, known as Gestalt perception. ...> Full Article


Minority participants crucial to effective aging studies (7/28/2011)

A new supplemental issue of the Gerontologist urges aging researchers to include representative samples of ethnically diverse populations in their work. The publication also identifies research priorities for moving the science of recruitment and retention forward, in addition to providing several strategies that scholars can employ in their work. The US Census Bureau predicts that non-white minorities will make up 42 percent of the country's 65-and-over population by 2050. ...> Full Article


1 in 3 Michigan seniors can't afford basics (7/27/2011)

According to a recent analysis by the Wayne State University Institute of Gerontology's Seniors Count! project, 37 percent of Michigan's seniors are living at or below a level of basic economic security. ...> Full Article


Testosterone deficiency and replacement therapy in men (7/26/2011)

Testosterone deficiency (TD), often referred to as hypogonadism, is associated with aging and affects approximately 30 percent of men ages 40-79. To highlight some of the challenges and controversies encountered in diagnosis and treatment of men with TD, the authors of a review article in the American Journal of Medicine introduced a clinical vignette to illustrate the implication of TD on men's overall health and analyzed a number of studies in men receiving testosterone replacement therapy to treat TD. ...> Full Article


New report shows seniors' economic security falling (7/25/2011)

The threat of budget negotiations stalling crucial social security payments have highlighted the growing pain felt by America's seniors. A new report "From Bad to Worse: Senior Economic Insecurity On the Rise," from the The Institute on Assets and Social Policy at Brandeis University and national policy center Demos, underscores how seniors have too few resources and too little time to plan for a fulfilling retirement. Report proposes real solutions to fix this growing crisis. ...> Full Article


Small hippocampus associated with depression in the elderly: Risk factor or shrinkage? (7/24/2011)

Imaging studies have repeatedly found that people with depression have smaller hippocampal volumes than healthy individuals. The hippocampus is a brain region involved in learning and memory, spatial navigation, and the evaluation of complex life situations or "contexts". It has been unclear whether a small hippocampus renders a person vulnerable to developing depression, or whether it is a consequence of depression. ...> Full Article


Study: Subsidizing wages at long-term care facilities would cut turnover (7/23/2011)

Study: Subsidizing wages at long-term care facilities would cut turnoverA government-sponsored wage-subsidy program could reduce the churn of low-wage caregivers through group homes by one-third, says Elizabeth T. Powers, a professor of economics and faculty member of the Institute of Government and Public Affairs at Illinois. ...> Full Article

Nursing home residents at heightened risk of falling in the days following drug changes (7/21/2011)

Nursing home residents taking certain antidepressant medications are at an increased risk of falling in the days following the start of a new prescription or a dose increase of their current drug, according to a new study by the Institute for Aging Research of Hebrew SeniorLife, an affiliate of Harvard Medical School. ...> Full Article


The secret to successful aging (7/17/2011)

Whether we choose to accept or fight it, the fact is that we will all age, but will we do so successfully? Aging successfully has been linked with the "positivity effect," a biased tendency towards and preference for positive, emotionally gratifying experiences. New research published in Biological Psychiatry now explains how and when this effect works in the brain. ...> Full Article


Researchers demystify a fountain of youth in the adult brain (7/15/2011)

Duke University Medical Center researchers have found that a "fountain of youth" that sustains the production of new neurons in the brains of rodents is also believed to be present in the human brain. The existence of a vital support system of cells around stem cells in the brain explains why stem cells by themselves can't generate neurons in a lab dish, a major roadblock in using these stem cells for injury repair. ...> Full Article


The truth about cats and dogs: Pets are good for mental health of 'everyday people' (7/14/2011)

Vitamin D can help elderly women survive (7/8/2011)

Giving vitamin D3 (cholecalciferol) to predominantly elderly women, mainly in institutional care, seems to increase survival. These women are likely to be vitamin D deficient with a significant risk of falls and fractures. This is the key conclusion in a systematic review published in the latest edition of The Cochrane Library. ...> Full Article


Twin study shows lifestyle, diet can significantly influence course of macular degeneration (7/7/2011)

Eating a diet high in vitamin D, as well as the nutrients betaine and methionine, might help reduce the risk of macular degeneration, according to new research conducted by Tufts Medical Center scientists. Their study of identical twins from the US World War II Twin Registry also found that the more a person smoked, the higher their risk of developing macular degeneration. ...> Full Article


Those aching joints could be in your genes (7/6/2011)

Those aching joints could be in your genesProf. Gregory Livshits of Tel Aviv University sampled a population of 2,500 identical and fraternal twins and found that genetic factors affect both spine degeneration and lower back pain. His discovery, recently published in the Annals of the Rheumatic Diseases, could revolutionize both the study and the treatment of the debilitating complaint. ...> Full Article


Web weaving skills provide clues to aging (7/5/2011)

Web weaving skills provide clues to agingYoung house spiders weave webs with perfect angles and regular patterns, but as they reach old age their webs deteriorate, showing gaping holes and erratic weaving. By using spiders as a simple model this research may provide insight into how age affects behavior in other organisms, including humans. This work will be presented at the Society for Experimental Biology Annual Conference in Glasgow on July 2, 2011. ...> Full Article
