[Q]: Question: Do nAT1 genotypes predict response to mesalamine in patients with ulcerative colitis?
Answer: NAT1 genotypes do not predict response or side effects to mesalamine in patients with UC. Variations caused by non-genomic effects may be associated with the clinical response to 5-ASA.
[A]: no

[Q]: 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.
[A]: yes

[Q]: Question: Do adenomas at resection margins influence the long-term development of pouch polyps after restorative proctocolectomy for familial adenomatous polyposis?
Answer: Incidence of pouch adenomas was low. There was no correlation between adenomas in the resection margins and the development of pouch adenomas.
[A]:
no
