Studies on the influence of quadriceps strength on knee osteoarthritis (OA), one of the leading causes of disability among the elderly, have shown conflicting results. In some studies, decreased quadriceps strength is associated with greater knee pain and impaired function, while other studies show mixed results on the effect of quadriceps strength on the structural progression of knee OA. http://www.physorg.com/news151089490.html Medicine & Health Tue, 13 Jan 2009 17:18:10 EST news151089490 A new randomized, prospective trial has shown that orlistat, a commonly prescribed inhibitor of fat absorption, does not help patients with fatty liver disease (FLD) lose weight, nor does it improve their liver enzymes or insulin resistance. These findings are in the January issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD). http://www.physorg.com/news151088581.html Medicine & Health Tue, 13 Jan 2009 17:03:01 EST news151088581 The scientists describe their work in this week's Early Edition of the Proceedings of the National Academy of Sciences. In the study, the team shows how the loss of the protein HMGB2, found in the surface layer of joint cartilage, leads to the progressive deterioration of the cartilage that is the hallmark of osteoarthritis. http://www.physorg.com/news150991956.html Medicine & Health Mon, 12 Jan 2009 14:12:36 EST news150991956 Counselling via the phone and internet can help weight management in overweight individuals, according to a Dutch study published in the open access journal, BMC Public Health. http://www.physorg.com/news150695972.html Medicine & Health Fri, 09 Jan 2009 03:59:32 EST news150695972 A preliminary study suggests that economic incentives appear to be effective for achieving short-term weight loss, according to a report in the December 10 issue of JAMA. http://www.physorg.com/news148067564.html Medicine & Health Tue, 09 Dec 2008 17:52:44 EST news148067564 Severely obese patients who have lost significant amounts of weight by changing their diet and exercise habits may be as successful in keeping the weight off long-term as those individuals who lost weight after bariatric surgery, according to a new study published online by the International Journal of Obesity. http://www.physorg.com/news147960005.html Medicine & Health Mon, 08 Dec 2008 12:00:05 EST news147960005 Diets that are high in protein and cereal grains produce an excess of acid in the body which may increase calcium excretion and weaken bones, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).
