Researchers link aging to cellular interactions that occur across generations (4/26/2014)

By studying the reproductive cells of nematodes -- tiny worms found in soil and compost bins -- Shawn Ahmed, Ph.D., an associate professor of genetics, identified the Piwi/piRNA genome silencing pathway, the loss of which results in infertility after many generations. He also found a signaling pathway -- a series of molecular interactions inside cells -- that he could tweak to overcome infertility while also causing the worms to live longer adult lives. ...> Full Article


Study examines risk of early death for people with mild cognitive impairment (4/24/2014)

One of the first studies to look at a relationship between death and the two types of mild cognitive impairment, or problems with memory and thinking abilities, suggests that people who have thinking problems but their memory is still intact might have a higher death rate in a period of six years compared to those who have no thinking or memory problems. ...> Full Article


Religious music brings benefit to seniors' mental health (4/19/2014)

A new article published online in The Gerontologist reports that among older Christians, listening to religious music is associated with a decrease in anxiety about death and increases in life satisfaction, self-esteem, and sense of control over their lives.

Scholars propose new standards for gauging muscle decline in older adults (4/16/2014)

Sarcopenia -- the age-related loss of muscle mass and strength -- may put up to 50 percent of seniors at greater risk for disability, yet there is no consensus within the medical community for how this condition should be measured. However, a new collection of articles appearing in the Journals of Gerontology, Series A: Biological Sciences and Medical Sciences lays out an empirically derived set of criteria for diagnosing sarcopenia. ...> Full Article


Seniors and sleeping pills: Empowered patients choose wisely (4/15/2014)

'Many people believe that involving patients in the decision to curtail medical treatments is expecting too much. On the contrary: we now have evidence that patients who are better informed make smarter choices.' -- Dr. Cara Tannenbaum, Institut universitaire de geriatrie de Montreal and University of Montreal. ...> Full Article


For sick, elderly patients, surgical decision making 'takes a village' (4/12/2014)

Surgery for sick, elderly patients can be very risky. Decision making surrounding a possible surgical procedure should be orchestrated by a multidisciplinary team, including the patient, his or her family, the surgeon, primary care physician, nurses and non-clinicians, such as social workers, advocates a perspective piece published in the New England Journal of Medicine. ...> Full Article


Physical activity is beneficial for late-life cognition (4/11/2014)

Physical activity in midlife seems to protect from dementia in old age, according to a study carried out at the University of Eastern Finland. Those who engaged in physical activity at least twice a week had a lower risk of dementia than those who were less active. The protective effects were particularly strong among overweight individuals. In addition, the results showed that becoming more physically active after midlife may also contribute to lowering dementia risk. ...> Full Article


Physical function and sense of autonomy determine life-space mobility in older people (4/10/2014)

Physical function and sense of autonomy are independent determinants of life-space mobility in older people. This was found in a study conducted at the Gerontology Research Center of the University of Jyväskylä. ...> Full Article

Yogurt did not impact OA progression in men or women. ...> Full Article


New research shows huge disparities between the decisions made by coroners (4/8/2014)

New research shows huge disparities between the decisions made by coronersDetailed analysis by Huddersfield researcher, ex-Detective Chief Superintendent Max Mclean, has shown that there are huge disparities between the decisions made by coroners in differing districts, with the troubling discovery that the deaths of women are considerably less likely to be investigated at an inquest. The result is a 'postcode lottery,' claims Mr Mclean, who calls for a fully-fledged National Coroners' Service, overseeing a reduced number of districts, headed by fully-professional coroners. ...> Full Article

Age-related decline in sleep quality might be reversible (4/5/2014)

Sleep is essential for human health. But with increasing age, many people experience a decline in sleep quality, which in turn reduces their quality of life. In a new study publishing April 1 in the open-access journal PLOS Biology, Scientists at the Max Planck Institute have investigated the mechanisms by which aging impairs sleep in the fruit fly. Their findings suggest that age-related sleep decline can be prevented and might even be reversible. ...> Full Article


Experts question routine mammograms in elderly (4/4/2014)

Doctors should focus on life expectancy when deciding whether to order mammograms for their oldest female patients, since the harms of screening likely outweigh the benefits unless women are expected to live at least another decade, according to a review of the scientific literature by experts at UCSF and Harvard medical schools. ...> Full Article


Hearing loss affects old people's personality (4/3/2014)

Hearing loss affects old people's personalityAs people approach old age, they generally become less outgoing. New research from the University of Gothenburg shows that this change in personality is amplified among people with impaired hearing. The findings emphasize the importance of acknowledging and treating hearing loss in the elderly population. ...> Full Article


Early cardiac risks linked to worse cognitive function in middle age (4/2/2014)

Young adults with such cardiac risk factors as high blood pressure and elevated glucose levels have significantly worse cognitive function in middle age, according to a new study by dementia researchers at University of California San Francisco. ...> Full Article


Poor sleep quality linked to cognitive decline in older men (4/1/2014)
