High Risk for Infection

1 Women More Likely to Be Catheterized in ER

Elderly women in hospital emergency rooms are more likely to have a catheter inappropriately placed than are men, finds a study conducted at St. John Hospital and Medical Center, Detroit. Urinary tract catheterization is a major risk factor for urinary tract infections (UTIs). UTIs account for more than 1/3 of all hospital-acquired infections and are of great concern to healthcare professionals, many of whom are trying to dramatically limit the incidence of preventable infection in patients. "The inappropriate UC [urinary catheter] utilization has been a ubiquitous problem in the hospital setting," say the study's authors. "This translates to additional preventable or avoidable urinary tract infections and other complications related to UCs."

2 Beet Juice May Improve Brain Health

Beet juice has been found to increase blood flow to the brain in older adults, find researchers at Wake Forest U, who say the study has great potential for combating the progression of dementia. "There have been several very high-profile studies showing that drinking beet juice can lower blood pressure, but we wanted to show that drinking beet juice also increases perfusion, or blood flow, to the brain," said researcher Daniel Kim-Shapiro. For the study, researchers examined how a daily dose of beet juice affects adults age 70 and over. Follow-up MRIs indicated increased blood flow to the frontal lobes, areas of the brain commonly associated with dementia. The university is working with a company to create and market a new beet-juice based beverage.

Some Fast Food OK

3 Weight Watchers Makes Changes in UK

Weight Watchers has rolled out fresh changes to its program, which will allow for occasional fast food or alcohol, reports CNN. Changes are also expected for the U.S. program, but they will be based on research of consumers in the U.S. A big change to the UK Weight Watchers program is the rethinking of the traditional point system, now called ProPoints. Users will be allowed 29 ProPoints instead of 18, and all fruits and most vegetables will carry no points. Weight Watchers made changes in the points system in order to consider fiber, protein, carbohydrate and fat content in food. The new U.S. points system will not be called ProPoints.

Can't Hurt, May Not Help

4 Toning Shoes May Not Really Tone

There's no convincing evidence that toning shoes actually help users burn more calories or tone their legs, says Edward R. Laskowski, M.D., a Mayo Clinic physical medicine and rehabilitation specialist. On Mayo Clinic's website, Dr. Laskowski takes on the question of whether toning shoes really work. He writes that while there's probably no harm in trying a pair of toning shoes, an independent study uncovered zero evidence that wearing the shoes improves muscle tone or causes more energy expenditure. However, Dr. Laskowski adds that if users feel that the shoes are comfortable and "not too unstable," then any additional exercise gained as a result of wearing the shoes can be beneficial to overall health.

Significant Decrease in Tumors

5 Black Raspberries Fight Colon Cancer in Mice

A study in two strains of mice that were genetically predisposed to intestinal tumors and colitis, which can lead to cancer, demonstrated that black raspberries significantly reduce colorectal tumors in mice. Mice were either fed a high-fat, low vitamin D diet or that diet plus 10 percent black raspberry powder for 12 weeks. There was a 45 percent reduction in tumor incidence and a 60 percent decrease in their number in Apc1638 mice. They work by preventing beta-catenin expression, a protein which binds Apc and impairs its tumor suppressor function. Tumor incidence and number was reduced by half in Muc2 mice and did so by decreasing inflammation. Protection was seen throughout the lower GI tract and based on these results researchers hope they will get money for human clinical trials.
