ROCHESTER, Minn — Feb. 3, 2014 — A new Mayo Clinic study found that among middle-aged men and women, 40 to 60 years old, the overall incidence of skin cancer increased nearly eightfold between 1970 and 2009, according to a study published in the January issue of Mayo Clinic Proceedings.

"The most striking finding was among women in that age group," says dermatologist Jerry Brewer, M.D., principal investigator of the study. "Women between 40 and 50 showed the highest rates of increase we've seen in any group so far."

With nearly one-third of Americans suffering from chronic pain, prescription opioid painkillers have become the leading form of treatment for this debilitating condition. Unfortunately, misuse of prescription opioids can lead to serious side effects—including death by overdose. A new treatment developed by University of Utah researcher Eric Garland has shown to not only lower pain but also decrease prescription opioid misuse among chronic pain patients.

There is a growing need for Cognitive Rehabilitation Therapy (CRT) due to  athletes with sports-related head injuries, a growing population with age-related cognitive decline and soldiers returning from war zones with brain injuries.

A special collection of articles in NeuroRehabilitation illustrates the art and science of restoring mental functioning in those who have suffered a debilitating injury or who may otherwise have problems with attention, comprehension, learning, remembering, problem solving, reasoning, and processing.

While the origin of life remains mysterious, scientists are finding more and more evidence that material created in space and delivered to Earth by comet and meteor impacts could have given a boost to the start of life. Some meteorites supply molecules that can be used as building blocks to make certain kinds of larger molecules that are critical for life.

February 03, 2014, OAKLAND, Calif. —Tests that require patients to collect a single stool sample at home and then send it to a lab for analysis will detect about 79 percent of colorectal cancers, according to a new evidence review published in the Annals of Internal Medicine. The review of 19 studies examining eight different fecal immunochemical tests, know as "FITs", also finds that the tests will correctly identify about 94 percent of patients who do not have cancers of the rectum or colon.

"We know the FIT is easy to use, and now we also know that it is a great tool for assessing which patients have cancer and which patients don't," said Beth Liles, MD, review co-author and clinical investigator at the Kaiser Permanente Center for Health Research in Portland, Ore.
