PROBLEM: Question: Is pre-surgical cortical activation to food pictures associated with weight loss following bariatric surgery?
Answer: We found that neural activity in previously established regions associated with cognitive and behavioral self-regulation predicts weight loss following bariatric surgery. These preliminary findings highlight the role of neural circuitry in the success and maintenance of weight loss and suggest a possible future use of fMRI in screening LAGB surgery candidates.

SOLUTION: yes

PROBLEM: Question: Is dorsal plication without degloving safe and effective for correcting ventral penile deformities?

SOLUTION: yes
