Giving up caffeine does not relieve tinnitus and acute caffeine withdrawal may actually add to the problem, according to a new study published in the International Journal of Audiology.
Researchers from the University of Bristol conducted a pseudo-randomised, double-blinded, placebo controlled study of phased caffeine withdrawal and abstention to test for a connection between caffeine consumption and tinnitus. Sixty-six volunteers who experienced tinnitus and who usually consumed at least 150 mg a day of caffeine took part in a 30-day trial. Their usual caffeinated…
If the coming Olympic games handed out gold medals for news coverage of medical topics, the coveted podium in a winner-takes-all contest would likely be a lonely place. Not that there aren't worthy contestants, but like figure skating's Michelle Kwan in 1998 and 2002, the hopefuls need a few tweaks before they can triple-axel their way to success.
The latest and greatest miracles, break-throughs, and fads are trumpeted in the news, and the newsroom's dwindling coffers combined with a "have to beat the other guys to it" 24-hour news cycle means consumers are often shortchanged.

Patients with chronic hepatitis C virus (HCV) who consume more than 308 mg of caffeine daily have milder liver fibrosis, according to a study featured in the January 2010 issue of Hepatology. The daily amount of caffeine intake found to be beneficial was equivalent to 2.25 cups of regular coffee, and other sources of caffeine beyond coffee did not have the same therapeutic effect.
From January 2006 to November 2008 all patients evaluated in the Liver Disease Branch of the National Institutes of Health were asked to complete a questionnaire to determine caffeine consumption. Questions…
Although running can confer many health benefits, the shoes runners wear while exercising may actually be doing them harm. In a study published in the December 2009 issue of PM&R: The journal of injury, function and rehabilitation, researchers compared the effects on knee, hip and ankle joint motions of running barefoot versus running in modern running shoes. They concluded that running shoes exerted more stress on these joints compared to running barefoot or walking in high-heeled shoes.
Sixty-eight healthy young adult runners (37 women), who run in typical, currently available running…
Ginkgo biloba, popularly consumed for its supposedly positive effect on memory, has no such effect, according to new research published in the December 23/30 issue of JAMA. In the study, older adults who used the herbal supplement for several years did not have a slower rate of cognitive decline compared to adults who received placebo .
"Ginkgo biloba is marketed widely and used with the hope of improving, preventing, or delaying cognitive impairment associated with aging and neurodegenerative disorders such as Alzheimer disease," the authors write. "Indeed, in the United States…
The right kind of stress response in the operating room could lead to quicker recovery for patients after knee surgery, according to a new study published in the Journal of Bone and Joint Surgery. The results could be used to develop methods for predicting how well patients will fare after they leave the hospital.
The study, conducted by researchers at Yale and Stanford, found that patients whose immune systems responded to the stress of surgery by mobilizing large numbers of pathogen-fighting cells and redistributing them to skin and other tissues recovered more quickly and completely than…
Out of the estimated 1 million people in the U.S. who suffer from chronic, severe angina -- chest pain due to blocked arteries -- about 300,000 cannot be helped by any traditional medical treatment such as angioplasty, bypass surgery or stents.
Recently, a nationwide study demonstrated that transplanting a potent form of adult stem cells into the heart muscle of patients with severe angina results in less pain and an improved ability to walk. The transplant patients also experienced fewer deaths than those who didn't receive stem cells. The findings of the study were presented at the…
Despite widespread educational efforts aimed at helping the public make healthy choices, it's understood among experts that people often fail to comply with the advice offered by their doctors and others in the health community.
To correct this deficiency in compliance, some researchers are now proposing that text messaging be used to send out health tips to consumers. Given it's popularity and low expense, they say, regular text messaging may be just the thing to prompt people to make behavioral changes for the sake of health
A recent study published in the November issue of Archives…
People associate all kinds of physical features with good health; a slim waistline, full head of hair, and chiseled abs are all typical examples. Now researchers are suggesting that another feature may tell an awful lot about a person's health--their skin color.
With the publication of a new study in the International Journal of Primatology, a team of scientists say that the color of a person's skin affects how healthy and therefore attractive they appear, and have found that diet may be crucial to achieving the most desirable complexion.
Using specialist computer software, a total of 54…
Contrary to conservative wisdom, exercising up to the end of pregnancy has no harmful effect on the health of the mother or child, and may even be beneficial for both, indicates a study published in the International Journal of Obesity.
160 healthy women between the ages of 25 and 35 took part in the study, all of whom had sedentary habits and no risk of premature birth. Of this group of women, half followed an exercise regime under the supervision of experts in Physical Activity and Sports Science in collaboration with the Gynaecology and Obstetrics Unit of Hospital Severo Ochoa in Madrid.…
