Knee arthritis improved by combined diet and exerciseKnee arthritis improved by combined diet and exercise Overweight and obese adults suffering from knee osteoarthritis may benefit more from combined intensive diet and exercise regimes, rather than undertaking diet or exercise regimes separately, according to a study published in JAMA.     Shorter radiation course appears effective for early breast cancer In women with early breast cancer, three weeks of high-dose radiation is as effective as the current standard — five weeks of lower-dose treatment, British researchers say. A short course of radiation given in larger doses — an approach called hypofractionated radiation — is safe and effective and causes less damage to healthy surrounding tissue, according to the 10-year results of two British trials published in The Lancet Oncology.
