Researchers Examine Effectiveness of Blocking Nerve to Help With Weight Loss

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.

Increase Seen in Use of Double Mastectomy

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.

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.
