Older adults with low levels of vitamin D in their blood may have double the risk of developing Alzheimer’s disease compared to seniors with sufficient vitamin D levels. In the study, the risk for dementia and Alzheimer’s significantly increased when vitamin D levels fell below 20 ng/ml. Experts believe that vitamin D may clear plaques in the brain linked with the development of dementia.

If you regularly dine out, you may be eating more than you should. A new study has found that people who regularly eat at restaurants average about 200 more calories more per day compared with those who cook at home. Study co-author Dr. Lisa Powell writes, “We always underestimate large portions, so people don’t realize that restaurant portions are as excessive as they are… This is why we need menu labeling on all restaurant meals, not just the fast-food and larger chains.”

Manual therapy in the form of thrust and non-thrust manipulation to the lower extremity was found to be successful in restoring normal movement patterns and pain-free function in a 40-year-old patient with chronic anterior knee pain and ankle sprain symptoms. The patient had suffered for one year from patellofemoral pain syndrome, which is characterized by pain or discomfort originating from the contact of the posterior surface of the kneecap with the thighbone.

The debate continues over the value of the Prostate-Specific Antigen (PSA) test to screen men for prostate cancer. A new study points out that testing reduces prostate cancer deaths, but overdiagnosis occurs in roughly 40% of cases detected by screening. This results in a high risk of overtreatment that can lead to incontinence and impotence. Further research is needed on ways to reduce overdiagnosis so that unnecessary biopsy procedures and treatments can be avoided.
