NCT01228097
This study will compare brain and hormone responses to food images (and food) in women who undergo: (1) gastric bypass surgery; (2) principally restrictive surgery (laparoscopic adjustable gastric banding or laparoscopic sleeve gastrectomy); or (3) no weight loss surgery, with the intent of remaining relatively weight stable (within 10-15 lb of your present weight). The investigators will use magnetic resonance imaging (MRI) to see how the brain responds to pictures of food and to consuming a liquid meal replacement. The investigators wish to determine whether the two surgeries have different effects on appetite, as observable in the brain, and whether the possible effects on appetite differ from those in participants who have a similar body weight but remain relatively weight stable. The investigators also will draw blood to determine how "hunger" and "fullness" hormones change after eating and to see if there are any differences among the three groups. The study is being sponsored by the National Institutes of Health (NIH).

NCT00002548
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage cancer cells. Combining chemotherapy and radiation therapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy and radiation therapy and kill more cancer cells. It is not yet known which treatment regimen is more effective for multiple myeloma. PURPOSE: Randomized phase III trial to compare the effectiveness of melphalan, total-body irradiation, and peripheral stem cell transplantation with that of combination chemotherapy in treating patients who have previously untreated multiple myeloma.
