Weight loss may prevent, treat osteoarthritis in obese patients

Obesity may trigger biomechanical changes, pathways that contribute to osteoarthritis

2013-03-09
(Press-News.org) ROSEMONT, Ill.—Weight loss may prevent and significantly alleviate the symptoms of osteoarthritis, a progressive disease of the joints known as "wear and tear" arthritis, according to a literature review appearing in the March 2013 issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS).

According to the article, obesity actually may trigger the biomechanical and inflammatory changes that cause osteoarthritis, and the pain and loss of mobility associated with the condition.

"There's a clear link between obesity and osteoarthritis, and the link is both from biomechanical factors as well as systemic factors. The systemic component appears to be significant," said Ryan C. Koonce, MD, an orthopaedic surgeon at Skagit Regional Clinics in Mount Vernon, Wash., and one of the authors of the literature review.

Approximately one half of osteoarthritis cases of the knee could be avoided in the U.S. if obesity was removed as a risk factor, according to the article. Other highlights include: Greater weight and load bearing across a particular joint leads to increased wear. White adipose tissue (WAT), a powerful endocrine organ that can trigger inflammation, is found in abundance in obese adults. Obesity is considered to be an underlying cause of hypertension, insulin resistance and other metabolic syndrome conditions. Obesity is a strong independent risk factor for pain, especially in soft-tissue structures such as tendons. Weight loss can diminish pain, and restore function and quality of life in osteoarthritis patients, and possibly avert approximately 111,206 total knee replacements each year.

"It's important that doctors are aware of the different ways that obesity causes arthritis not only for treatment but for prevention of the condition," said Jonathan T. Bravman, MD, assistant professor in the Department of Orthopaedics at the University of Colorado, an orthopaedic surgeon, and a co-author of the study. "We are underutilizing weight loss as a primary treatment option for arthritis and joint pain."

NIST quantum refrigerator offers extreme cooling and convenience

NIST quantum refrigerator offers extreme cooling and convenience
2013-03-09
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a solid-state refrigerator that uses quantum physics in micro- and nanostructures to cool a much larger object to extremely low temperatures. What's more, the prototype NIST refrigerator, which measures a few inches in outer dimensions, enables researchers to place any suitable object in the cooling zone and later remove and replace it, similar to an all-purpose kitchen refrigerator. The cooling power is the equivalent of a window-mounted air conditioner cooling a building the size ...

New NIST time code to boost reception for radio-controlled clocks

2013-03-09
The National Institute of Standards and Technology (NIST) is changing the way it broadcasts time signals that synchronize radio-controlled "atomic" clocks and watches to official U.S. time in ways that will enable new radio-controlled timepieces to be significantly more robust and reliable. This new time broadcast protocol will not only improve the performance of new radio-controlled clocks and watches, but will encourage the development of new timekeeping products that were not practical with the old broadcast system because of local interference or other limitations. ...

Study shows confidence builds better exercise habits for cancer survivors

2013-03-09
HOUSTON - Endometrial cancer survivors are more likely to complete physical activity, and for longer durations, when their daily self-efficacy is higher, according to a study published online in the journal Health Psychology – a publication of the American Psychology Association. "Sedentary behavior is associated with increased cancer risk, including endometrial cancer," said Karen Basen-Engquist, Ph.D., professor in the Department of Behavioral Science at MD Anderson and lead investigator on the study. "When cancer survivors exercise, it not only improves their physical ...

To speed development and adoption of electronic health records (EHRs) for pediatrics, a group of experts from industry, academia and government convened by the National Institute of Standards and Technology (NIST) has focused its attention on three key audiences—records-system vendors and developers, small-group pediatric medical practices and children's hospitals. In a paper* in The Joint Commission Journal on Quality and Patient Safety, the panel of medical, human factors engineering and software-usability experts detail how specific recommendations from a recent guide ...

Why a hereditary anemia is caused by genetic mutation in mechanically sensitive ion channel

2013-03-09
BUFFALO, N.Y. – A genetic mutation that alters the kinetics of an ion channel in red blood cells has been identified as the cause behind a hereditary anemia, according to a paper (http://bit.ly/13LgCzc) published this month in the Proceedings of the National Academy of Sciences by University at Buffalo scientists and colleagues. The research team was led by Frederick Sachs, PhD, SUNY Distinguished Professor in the UB Department of Physiology and Biophysics, who discovered in the 1980s that some ion channels are mechanosensitive, that is, they convert mechanical stress ...

Tiny biomolecular chambers called nanopores that can be selectively heated may help doctors diagnose disease more effectively if recent research by a team at the National Institute of Standards and Technology (NIST), Wheaton College, and Virginia Commonwealth University (VCU) proves effective. Though the findings* may be years away from application in the clinic, they may one day improve doctors' ability to search the bloodstream quickly for indicators of disease—a longstanding goal of medical research. The team has pioneered work on the use of nanopores—tiny chambers ...

Some biologists shun new media

2013-03-09
Although biologists think that "new media" such as blogs and online social networks have an important influence on public opinion and political decisions, they aren't much inclined to use them themselves to stay informed about developments in science. Rather, they prefer traditional outlets such as newspapers and television. That seems, at least, to be the implication of a study published in the April issue of BioScience. The study, by Joachim Allgaier of the Jülich Research Center in Germany and four coauthors, examined the opinions of 257 neuroscientists working in ...
