Prescribing antibiotics for patients with discoloured phlegm caused by acute cough has little or no effect on alleviating symptoms and recovery, a Cardiff University study has found.

A new scientific study positions walnuts in the number one slot among a family of foods that lay claim to being among Mother Nature's most nearly perfect packaged foods: Tree and ground nuts. In a report given in Anaheim, California at the 241st National Meeting & Exposition of the American Chemical Society on March 27, scientists presented an analysis showing that walnuts have a combination of more healthful antioxidants and higher quality antioxidants than any other nut.

The numbers are, well, depressing: More than 2 million people age 65 and older suffer from depression, including 50 percent of those living in nursing homes. The suicide rate among white men over 85 is the highest in the country -- six times the national rate. And we're not getting any younger. In the next 35 years, the number of Americans over 65 will double and the number of those over 85 will triple.

Research from Karolinska Institutet in Sweden shows that a specific inflammatory factor may be important in the development of the heart valve disease aortic stenosis. The results suggest that anti-inflammatory medication could be a possible new treatment.

Post-marathon sniffles are a common complaint among runners, but they are often put down to infections taking advantage of a depleted immune system caused by the effort involved. Now, however...

I wrote this review on potassium iodide a few years ago. The pills, also known as “KI,” prevent the thyroid gland from absorbing radiation released from nuclear weapons and nuclear power plants if taken within 24-hours of exposure. Seems relevant, especially for those of us on the West Coast who are monitoring the situation with the Japanese nuclear power plants.

As many as 100 million Americans may currently be misclassified as having abnormal blood pressure, according to Dr. Brent Taylor from the Veterans Affairs Health Care System in Minneapolis and the University of Minnesota and his colleagues. Their findings show that these people are not actually more likely to die prematurely than those with 'normal' blood pressure, i.e. below 120/80.

Scientists have long puzzled over the many hours we spend in light, dreamless slumber. But a new study from the University of California, Berkeley, suggests we're busy recharging our brain's learning capacity during this traditionally undervalued phase of sleep, which can take up half the night.

The liver normally makes and stores fat, which is required in moderation for normal body function. However, if the process goes awry, excess fat in the liver can cause major liver damage. In fact, fatty liver is a leading cause of liver failure in the United States, and is often brought on by obesity and diabetes. In turn, the increasing prevalence of these diseases has brought with it an epidemic of liver disease.

ScienceDaily (Mar. 7, 2011) — Eating more tomatoes and tomato products can make people healthier and decrease the risk of conditions such as cancer, osteoporosis and cardiovascular disease, according to a review article the American Journal of Lifestyle Medicine (published by SAGE).
