Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: This longitudinal study had three aims: 1) determine the extent to which boys at high average risk and low average risk for substance use disorder differ on a construct of neurobehavioral disinhibition, 2) evaluate the capacity of neurobehavioral disinhibition to predict substance use frequency at age 16, and 3) demonstrate the utility of neurobehavioral disinhibition in predicting substance use disorder.', 'The authors derived an index of neurobehavioral disinhibition from measures of affect, behavior, and cognition. The neurobehavioral disinhibition score was used to discriminate youth at high and low average risk for substance use disorder and to predict substance use frequency after 4-6 years and substance use disorder after 7-9 years.', 'The neurobehavioral disorder score significantly discriminated boys at high average risk from those at low average risk at ages 10-12. Neurobehavioral disinhibition at age 16, in conjunction with substance use frequency and risk status group, predicted substance use disorder at age 19 with 85% accuracy and accounted for 50% of the variance in Drug Use Screening Inventory overall problem density score. Neurobehavioral disinhibition was a stronger predictor of substance use disorder (odds ratio=6.83) than substance consumption frequency (odds ratio=3.19).

Output: Does neurobehavioral disinhibition in childhood predict early age at onset of substance use disorder?

Input: Consider Input: Conflicting results have been reported regarding the predicative roles of alloreactive natural killer (NK) cells on the outcomes of transplantation in leukaemia patients.', 'We prospectively analysed the human leukocyte antigen (HLA) typing of donor-recipient pairs and the KIR typing of the donors in 97 CML patients to address the predictive roles of NK cells in relapse undergoing T-cell-replete haploidentical transplantation.', "Patients with class I ligands for the donor-inhibitory KIR gene exhibited decreased molecular and haematologic relapse rates (P=0.003 and P=0.015, respectively). There was a significantly reduced risk of molecular and haematologic relapse in patients with HLA-C1C2 or C2C2 who accepted donors with KIR2DS1 or in patients with HLA-Bw4 who accepted donors with KIR3DS1 ('recipient with relevant KIR ligand for donor-activating KIR', n=25), compared with the remaining transplants (n=72, P=0.009 and P=0.009, respectively). In addition, the presence of class I ligand in the recipients of donor-activating KIR contributed to a decreased relapse rate in patients lacking class I ligand in the recipient of donor-inhibitory KIR (P=0.04 and P=0.03, respectively).

Output: Does hLA and KIR genotyping correlate with relapse after T-cell-replete haploidentical transplantation in chronic myeloid leukaemia patients?

Input: Consider Input: Patients with familial adenomatous polyposis (FAP) are prone to developing duodenal adenoma and cancer. Optimal surveillance and management of these adenomas are not well established.', 'We assessed the outcome of FAP patients undergoing intense multimodal surveillance and subsequent endoscopic resection of advanced lesions.', 'Eighty consecutive FAP patients enrolled during 2001 to 2011 from the Familial Cancer Clinic of a tertiary hospital as part of routine surveillance.', 'Case series, prospective in years 2006 to 2011 and retrospective in years 2001 to2006.', 'Patients were followed by annual forward-view and/or side-view upper endoscopy. Abiopsy sample was obtained from visible lesions and normal papillae. Ampullary adenomas were further assessed by EUS to determine dimensions and resectability. Advanced adenomas (size 10mm, villous type, high-grade dysplasia) underwent endoscopic ampullectomy or polypectomy and continued surveillance.', 'Detection of advanced adenomas by endoscopy and EUS, endoscopic maintenance of duodenum free of advanced adenoma and cancer.', 'Patients (38 men and 42 women, mean age 32.68 13.60) were followed 7.2 years and underwent 5.36diagnostic studies on average. Thirty-eight patients had ampullary adenomas. Advanced adenoma was diagnosed by endoscopy in 10 patients. Importantly, EUS upstaged 9 additional patients to advanced adenoma and downstaged 1, thus altering the treatment course in 36% of patients performing EUS. Endoscopic ampullectomy was performed in 15 patients. Adenoma recurred in 10. Five remained nonadvanced and 5 in advanced stages: 3 were successfully retreated endoscopically and 2 ultimately required surgery for residual adenoma. Advanced nonampullary adenomas were successfully resected endoscopically in 23 patients. No patient had duodenal cancer during the study period.
Output: Are endoscopy and EUS key for effective surveillance and management of duodenal adenomas in familial adenomatous polyposis?
