Exercise Programs Focusing On Muscle Density Could Reduce Disability And Hospitalization Of The Elderly
Older adults who have less strength, poor physical function and low muscle density are at higher risk of being hospitalized compared to adults with more strength and better function. That"s the finding of a new study in the Journal of the American Geriatric Society.

Crohn's Disease: Case Western Reserve Researchers Identify Links Between Inflammatory Disease Genes
Researchers from Case Western Reserve University School of Medicine identified a novel link between ITCH, a gene known to regulate inflammation in the body and NOD2, a gene which causes the majority of genetic Crohn"s Disease diagnoses. ITCH, when malfunctioning, causes widespread inflammatory diseases, including inflammatory bowel disease, gastritis, uncontrolled skin inflammation, and pulmonary pneumonitis. Derek Abbott, M.D., Ph.D., and his team of researchers found that ITCH also influences NOD2-induced inflammation. These findings, published in the August 11th issue of Current Biology, suggest a common pathophysiology exists between multiple inflammatory diseases. The unexpected finding of the interaction between these genes offers the possibility of a new drug target, which would be effective in treating Crohn"s disease - a chronic disorder causing inflammation of the gastrointestinal tract.

Stem Cells Embedded In Sutures To Enhance Healing
Johns Hopkins biomedical engineering students have demonstrated a practical way to embed a patient"s own adult stem cells in the surgical thread that doctors use to repair serious orthopedic injuries such as ruptured tendons. The goal, the students said, is to enhance healing and reduce the likelihood of re-injury without changing the surgical procedure itself.

Chief Medical Officer Otis Brawley Responds To Medicare Decision On CT Colonography

Chief Medical Officer Otis W. Brawley, M.D. responds to Medicare"s decision not to cover CT colonography "I am disappointed in this decision, as randomized clinical trials clearly show CT colonography (CTC) is as effective as optical colonoscopy for the early detection of early cancers and pre-malignant lesions. Medicare coverage for CTC, also known as virtual colonoscopy, would have provided an additional option for colorectal cancer screening. Additional options are absolutely necessary as the supply of gastroenterologists and other trained specialists is currently inadequate to supply optical colonoscopy to all of those who need it, and many people are unwilling to undergo colonoscopy or other currently reimbursed tests. It is our belief that by increasing the proportion of Americans 50 and over who get colorectal cancer screening, we could increase the number of lives saved from this devastating disease and decrease long term medical costs. Providing access to all proven screening options is even more important for those in the Medicare population, most of whom are at even greater risk of developing and dying from colorectal cancer due to their advanced age. The American Cancer Society still believes that a battery of different tests for colorectal cancer screening should be available to the American people. This includes optical colonoscopy, virtual colonoscopy, stool blood testing, as well as sigmoidoscopy." American Cancer Society
