Study shows the MDHearingAid to be an effective low cost solution to hearing loss

2012-09-28
(Press-News.org) Washington, D.C. - A study presented at the American Academy of Otolaryngology - Head & Neck Surgery Foundation Annual Meeting in Washington, D.C. shows that the MD Hearing Aid line offers a reasonable low-cost solution to those who are not using hearing aids or other amplification devices because of cost concerns.

In the study, researchers at the Michigan Ear Institute sought to evaluate a novel, inexpensive (under $200.) over- the-counter hearing aid regarding to its acoustic properties and also to test the hearing aid on patients with varying levels of hearing loss to evaluate their perceived benefit by using validated questionnaires.

Hearing loss affects approximately 34 million people in the United States, but hearing aid usage rates have historically remained at just 24%. One major reason for this low rate of use is that hearing aids are typically very expensive, with the average cost of a single hearing aid approximately $1,900. Medicare and most insurance companies do not cover this cost. Many medical studies have linked untreated hearing loss in the elderly with a higher risk of social isolation, depression, anxiety, and symptoms consistent with Alzheimer's dementia.

The MDHearingAid was evaluated using a Fonix 6500c Hearing Aid Analyzer, measured according to accepted standards. The measurements included saturated sound pressure level curve, high-frequency average full-on gain, frequency response, total harmonic distortion, equivalent input noise level, and input-output curve. Then the device was tested on a group of participants with mild to moderately-severe hearing loss who were unwilling or unable to purchase a custom hearing aid due to cost considerations. The participants were asked to wear the device for a minimum of 30 days and complete these self-reported surveys: "International Outcome Inventory - Hearing Aids" and "Satisfaction with Amplification in Daily Living".

Researcher Seilesh Babu, M.D. found that the MDHearingAid met the acoustic targets. All participants demonstrated user satisfaction scores that were within the standard range for patients with mild to moderately-severe hearing loss. The study found that the low-cost MDHearingAid is electroacoustically adequate and a reasonable low-cost solution to meet the needs of those value- and cost-conscious patients who were not using amplification via a custom hearing device.

Dr. Babu stated that further development and investigation of these instruments is warranted, to provide a potential opportunity for greater numbers of persons with hearing loss to have access to hearing aids and reap the medical, social, and emotional benefits from improved communicative abilities.

Dr. Seilesh Babu is a board-certified Otolaryngologist and a Nationally Recognized expert in ear surgery, hearing loss, dizziness, and other inner ear disorders in children and adults. Dr Babu has numerous articles and book chapters written in these areas. SOURCE: Presented at the American Academy of Otolaryngology-Head & Neck Surgery Foundation Annual Meeting, Sept 9, 2012

This press release is available in French and German.MONTREAL, Canada, September 28, 2012 - Researchers at the Sainte-Justine University Hospital Center and University of Montreal have identified genetic origins in 10% of an important form of congenital heart diseases by studying the genetic variability within families. "This is more than the sum of the genes found to date in all previous studies, which explained only 1% of the disease, says Dr. Marc-Phillip Hitz, lead author of the study published in PLOS Genetics, under the direction of Dr. Gregor Andelfinger, pediatric ...

Making headway on beta-blockers and sleep

2012-09-28
Boston, MA—Over 20 million people in the United States take beta-blockers, a medication commonly prescribed for cardiovascular issues, anxiety, hypertension and more. Many of these same people also have trouble sleeping, a side effect possibly related to the fact that these medications suppress night-time melatonin production. Researchers at Brigham and Women's Hospital (BWH) have found that melatonin supplementation significantly improved sleep in hypertensive patients taking beta-blockers. The study will be electronically published on September 28, 2012 and will be ...

Gout guidelines arm patients and physicians with tools to fight painful disease

2012-09-28
Gout is one of the most common forms of inflammatory arthritis, affecting nearly 4% of adult Americans. Newly approved guidelines that educate patients in effective methods to prevent gout attacks and provide physicians with recommended therapies for long-term management of this painful disease are published in Arthritis Care & Research, a peer-reviewed journal of the American College of Rheumatology (ACR). Uric acid is produced by the metabolism of purines, which are found in foods and human tissue. When uric acid levels increase, crystals can form and deposit in joints, ...

Eating cherries lowers risk of gout attacks by 35%

2012-09-28
A new study found that patients with gout who consumed cherries over a two-day period showed a 35% lower risk of gout attacks compared to those who did not eat the fruit. Findings from this case-crossover study published in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), also suggest that risk of gout flares was 75% lower when cherry intake was combined with the uric-acid reducing drug, allopurinol, than in periods without exposure to cherries or treatment. Previous research reports that 8.3 million adults in the U.S. suffer with gout, ...

Learning to live on mars

2012-09-28
Boston, MA—Since the beginning of August, NASA's Mars rover, Curiosity, has been roaming all over the distant planet learning as much as it can about the Martian terrain. The mission control team back on Earth has also learned what it may be like on Mars by trying to live and work on a Martian day, which is about 40 minutes longer than an Earth day. This 'day' length causes havoc with the internal 24-hour body clock but researchers at Brigham and Women's Hospital (BWH) have developed and tested a fatigue management program which is successful at controlling this space-age ...
