COLUMBIA, Mo. – This year, more than 230,000 women will be diagnosed with breast cancer and nearly 40,000 women will not survive their battle with cancer, according to the American Cancer Society. New research from the University of Missouri shows that certain factors, including marital status, having children in the home, income level and age, affect the likelihood of depression in breast cancer survivors. Further, depressed patients are less likely to adhere to medication regimens, potentially complicating the progress of their treatment. (more…)

Iron overload is a common condition affecting millions of people worldwide. Excess iron in the body is toxic, and deposits can cause damage to the liver, heart and other organs. Current treatments, researchers say, are not ideal and have significant side effects.

Iron in the body is regulated by a hormone called hepcidin, and a deficiency in this hormone can cause the iron overload seen in genetic disorders like hereditary hemochromatosis and Cooley’s anemia. (more…)

Nearly 18% of All Clicks from Flu Searches in September Drive Traffic to CDC.gov

RESTON, VA, November 1, 2011 – comScore, Inc., a leader in measuring the digital world, today released a study of audience visitation to public health sites in the U.S. The study found that health-focused sites represented 3 out of the top 10 federal Government sites in September, indicating a high level of public interest in health information. NIH.gov, the flagship property of the National Institutes of Health, drew 10.6 million Americans in September 2011, making it the most popular site in the Government category. (more…)

More Power to the Cranberry: Study Shows the Juice is Better than Extracts at Fighting Bacterial Infections

With scientific evidence now supporting the age-old wisdom that cranberries, whether in sauce or as juice, prevent urinary tract infections, people have wondered if there was an element of the berry that, if extracted and condensed, perhaps in pill form, would be as effective as drinking the juice or eating cranberry sauce. A new study from researchers at Worcester Polytechnic Institute helps to answer that question. (more…)

A surprising new University of Colorado Boulder study shows that huge amounts of fatty acids circulating in the bloodstreams of feeding pythons promote healthy heart growth, results that may have implications for treating human heart disease.

CU-Boulder Professor Leslie Leinwand and her research team found the amount of triglycerides — the main constituent of natural fats and oils — in the blood of Burmese pythons one day after eating increased by more than fiftyfold. Despite the massive amount of fatty acids in the python bloodstream there was no evidence of fat deposition in the heart, and the researchers also saw an increase in the activity of a key enzyme known to protect the heart from damage.

You Are What You Eat: Low-Fat Diet with Fish Oil Slows Growth of Prostate Cancer Cells

Men who ate a low-fat diet with fish oil supplements for four to six weeks before having their prostate removed had slower cancer-cell growth in their prostate tissue than men who ate a traditional, high-fat Western diet, according to a study by researchers at UCLA’s Jonsson Comprehensive Cancer Center.

The researchers also found a change in the composition of cell membranes in both healthy cells and cancer cells in the prostates of men on the low-fat, fish oil–supplement diet. The membranes had heightened levels of omega-3 fatty acids from fish oil and decreased levels of omega-6 fatty acids from corn oil, which may directly affect the biology of the cells, though further studies are needed, said Dr. William Aronson, the study’s first author and a researcher with the Jonsson Cancer Center.
