Researchers examine effectiveness of blocking nerve to help with weight loss

Researchers examine effectiveness of blocking nerve to help with weight loss

Among patients with morbid obesity, blocking the vagus nerve, which plays a role with appetite and metabolism, did not meet pre-specified efficacy objectives compared to a control group, although the intervention did result in greater weight loss, according to a study in the September 3 issue of JAMA . Bariatric surgery can produce significant weight loss and improvement in health but is associated with several potential adverse effects. There is interest in the development of a device that could be as effective or nearly as effective as bariatric surgery but has fewer risks and is less invasive Continue reading

Change in type of procedure most commonly used for bariatric surgery

In an analysis of the type of bariatric surgery procedures used in Michigan in recent years, sleeve gastrectomy (SG) surpassed Roux-en-Y gastric bypass (RYGB) in 2012 as the most common procedure performed for patients seeking this type of surgery, and SG became the predominant bariatric surgery procedure for patients with type 2 diabetes, according to a study in the September 3 issue of JAMA .

Bariatric surgery is the most effective therapy available for significant and sustainable weight loss in patients with morbid obesity, and its use has increased during the last decade Continue reading

Increase seen in use of double mastectomy, although not associated with reduced death

Increase seen in use of double mastectomy, although not associated with reduced death

Among women diagnosed with early-stage breast cancer in California, the percentage undergoing a double mastectomy increased substantially between 1998 and 2011, although this procedure was not associated with a lower risk of death than breast-conserving surgery plus radiation, according to a study in the September 3 issue of JAMA . The authors did find that surgery for the removal of one breast was associated with a higher risk of death than the other options examined in the study. Continue reading

The authors did find that surgery for the removal of one breast was associated with a higher risk of death than the other options examined in the study. Randomized trials have demonstrated similar survival for patients with early-stage breast cancer treated with breast-conserving surgery and radiation or with mastectomy. Continue reading

Comparison of named diet programs finds little difference in weight loss outcomes

Comparison of named diet programs finds little difference in weight loss outcomes

In an analysis of data from nearly 50 trials including about 7,300 individuals, significant weight loss was observed with any low-carbohydrate or low-fat diet, with weight loss differences between diet programs small, findings that support the practice of recommending any diet that a patient will adhere to in order to lose weight, according to a study in the September 3 issue of JAMA . Named or branded (trade-marked) weight loss programs provide structured dietary and lifestyle recommendations via popular books and in-person or online behavioral support and represent a multibillion dollar industry. Debate regarding the relative merit of the diets is accompanied by advertising claiming which macronutrient composition is superior, such as a low-carbohydrate or low-fat diet. Continue reading

‘Treatments waiting to be discovered’ inside new database

Your genes are blueprints for proteins, and molecules called microRNA can help to determine how often these genetic blueprints are manufactured into proteins. Researchers often ask what microRNA regulates a gene related to disease. Or what gene is regulated by a microRNA found in sick patients Continue reading

Growth hormone analog may reduce risk of fatty liver disease in HIV-infected patients

Growth hormone analog may reduce risk of fatty liver disease in HIV-infected patients

In a preliminary study, HIV-infected patients with excess abdominal fat who received the growth hormone-releasing hormone analog tesamorelin for 6 months experienced modest reductions in liver fat, according to a study in the July 23/30 issue of JAMA , a theme issue on HIV/AIDS. Patients infected with HIV demonstrate a high prevalence of nonalcoholic fatty liver disease, estimated at 30 percent to 40 percent Continue reading
