Hearing Study Focuses On AIDS Patients

Specialists in HIV and in hearing at the University of Rochester Medical Center are teaming up to measure the hearing of people with AIDS. The five-year study is believed to be the first large study of its kind testing the hearing of people with HIV/AIDS and comparing the results with those from people without HIV. The new effort, supported by a $1.9 million grant from the National Institute on Deafness and Other Communication Disorders, is the result of collaboration between hearing experts and experts on HIV and AIDS. The study is led by Amneris Luque, M.D., associate professor of Medicine and director of Strong Memorial Hospital's AIDS Clinic, which provides care for more than 900 patients.

'Escaped' Proteins Add To Hearing Loss In Elderly, University Of Florida Researchers Found

Age-related hearing loss is the most common sensory disorder among the elderly. But scientists are still trying to figure out what cellular processes govern or contribute to the loss. Now a University of Florida team and researchers from University of Wisconsin and three other institutions have identified a protein that is central to processes that cause oxidative damage to cells and lead to age-related hearing loss. The findings help point the way toward a new target for antioxidant therapies and will be published online this week in the Proceedings of the National Academy of Sciences. One theory of aging holds that free radicals damage components of mitochondria, the energy center of cells.

Mouse Study Sheds Light On Hearing Loss In Older Adults

Becoming "hard of hearing" is a standard but unfortunate part of aging: A syndrome called age-related hearing loss affects about 40 percent of people over 65 in the United States, and will afflict an estimated 28 million Americans by 2030. "Age-related hearing loss is a very common symptom of aging in humans, and also is universal among mammal species, and it's one of the earliest detectable sensory changes in aging, " says Tomas Prolla, a professor of genetics and medical genetics at the University of Wisconsin-Madison. Prolla is senior author of a paper in today's (Nov. 9) PNAS that looks at the genetic roots of this type of hearing loss, which is not due to noise exposure.

Scientists Create A 'Golden Ear' Mouse With Great Hearing As It Ages

What do you get when you cross a mouse with poor hearing and a mouse with even worse hearing? Ironically, a new strain of mice with "golden ears" - mice that have outstanding hearing as they age. The work by one of the world's foremost groups in age-related hearing loss, or presbycusis, marks the first time that scientists have created the mouse equivalent of a person with "golden ears" - people who are able to retain great hearing even as they grow older. The research at the University of Rochester Medical Center was published online recently in the journal Neurobiology of Aging. The new mouse is expected to offer clues about how these lucky folks are able to retain outstanding hearing even through old age.

Sonic Innovations Warns Hearing Loss Affects Income Loss

Sonic Innovations, a U.S.-based digital hearing aid manufacturer, warns Americans who ignore a hearing loss are also losing income. A study from the Better Hearing Institute (BHI), a non-profit corporation that educates the public about the neglected problem of hearing loss and what can be done about it, gives the numbers. $100 Billion Lost in Earnings Each Yearâ - Average annual amount of income lost by American working people who don't get hearing aids ranges from $1, 000 (those with mild hearing loss) to $12, 000 (those with profound hearing loss). - BHI survey states that getting hearing aids at a younger age reduces the chance of losing income.
