Knee replacement cuts heart risks

NEW YORK: For people with severe arthritis,knee or hip replacement may have an added benefit: a reduction in the risk for cardiovascular disease. Canadian researchers selected 153 people with moderate to severe osteoarthritis who had had a knee or hip replacement and 153 who had not. The groups were matched for severity of arthritis,age,income,smoking status,diabetes and other factors. Then the researchers followed them for seven years,during which there were 111 instances of a serious cardiovascular event heart attack,stroke,heart failure,coronary artery bypass surgery,angioplasty or death from cardiovascular disease. The study was posted online in BMJ,the medical journal. Compared with those who had neither knee nor hip surgery,those who had an operation were 40 per cent less likely to have a cardiovascular event. Patients who had at least one risk factor for cardiovascular disease also benefited. NYT

Eye treatment benefits may be exaggerated

NEW YORK: News reports often overhype the potential benefits of novel treatments for disabling eye diseases,a new study suggests. Broadcast and Internet news reports,in particular,tended to be more enthusiastic about so-called retinal implants than the studies they were based on,researchers found. And the stories werent always scientifically accurate. The hope is that such implants could one day help people who lose much of their eyesight due to macular degeneration or other diseases that damage the retina. But scientists are still far from a guaranteed fix. Some of the implants have yet to be tested in humans. The promise is real. The availability is non-existent right now except in very limited trials,and the results are encouraging but honestly fairly limited at this point, Dr Jack Cioffi,head of ophthalmology at Columbia University Medical Center in New York,said. Researchers analysed 93 news reports published between 1999 and 2012. REUTERS
