In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Input: Consider Input: Context: We measured the effect of two weight adjusted i.v. doses (0.2 mg per 70 kg and 0.4 mg per 70 kg) of the potent opioid buprenorphine on analgesia and respiratory depression in healthy volunteers. The aim of the study was to compare buprenorphine's behaviour with respect to the occurrence of ceiling (or apparent maximum) in these typical micro-opioid protein-(MOP) receptor effects.", 'Ten subjects (5 males) received 0.2 mg per 70 kg, 10 others (5 males) 0.4 mg per 70 kg i.v. buprenorphine. Steady-state inspired minute ventilation at a fixed end-tidal Pco(2) of 7 kPa was measured before drug infusion and at regular intervals after drug infusion. Experimental pain was induced using transcutaneous electrical stimulation and a gradually increasing current. Pain tolerance was measured at regular intervals before and after drug infusion. The studies lasted 8 h.', 'After infusion of the drug ventilation showed a rapid decline and reached peak depression between 150 and 180 min after drug administration. This effect was dose-independent with respect to timing and magnitude. At peak respiratory depression minute ventilation was 13.1 (sd 1.8) litre min(-1) in the 0.2 mg group vs 12.0 (sd 1.3) litre min(-1) in the 0.4 mg group (n.s.). At buprenorphine 0.2 mg a small short-lived analgesic effect was observed with a maximum increase in pain tolerance current of 6.7 (sd 2.8) mA occurring at 75 min after drug administration. Peak analgesic effect was 29% above baseline current. In contrast, buprenorphine 0.4 mg caused a large and long-lived analgesic effect with a maximum increase in pain tolerance current of 23.8 (sd 7.4) mA occurring at 130 min after drug administration. Peak analgesic effect was 160% above baseline current (0.4 vs 0.2 mg, P<0.01).\Question: Does buprenorphine induce ceiling in respiratory depression but not in analgesia?

Output: While buprenorphine's analgesic effect increased significantly, respiratory depression was similar in magnitude and timing for the two doses tested. We conclude that over the dose range tested buprenorphine displays ceiling in respiratory effect but none in analgesic effect.


Input: Consider Input: Context: Crohn's disease is a heterogeneous inflammatory bowel disease. The impact of age at diagnosis on the clinical course of patients varies widely as reported in the Western literature. Using the Vienna Classification, we seek to determine whether young Crohn's disease patients in an Asian population followed a different clinical course than old patients.", "The case records of 100 Crohn's disease patients who were treated at the Inflammatory Bowel Disease Center, Singapore General Hospital, were studied retrospectively. The age group and location of disease and behavior according to the Vienna classification were determined at diagnosis.", 'A1 group (age <40 years) defined as "young" and A2 group (age > or =40) defined as "old" contained 65 and 35 patients, respectively. Median age for the young group was 27.4 years and that for the old group was 52.6 years. Of the young patients, 66.7% flared at least once compared with 28.6% of the old patients, odds ratio of 5.0 (P < 0.001). Young patients were more likely to be steroid dependent (20.0% of A1 versus 8.6% of A2, P = 0.14), received azathioprine (38.5% of A1 versus 5.7% of A2, P < 0.001) and experienced complications (31% of A1 versus 20% of A2, P = 0.25)-numerically higher rates that did not reach statistical significance. There was no significant difference between the age groups for the location and behavior of disease as well as requirement for surgery.\Question: Does crohn 's disease run a more aggressive course in young Asian patients?

Output: In this first Asian study looking specifically at the impact of age at diagnosis of Crohn's disease, we found that young patients underwent a more aggressive clinical course.


Input: Consider Input: Context: The normal anterior translation of the articular surface of the distal humerus with respect to the humeral diaphysis facilitates elbow flexion. We hypothesize that there is a correlation between anterior translation of the distal humeral articular surface and flexion after open reduction and internal fixation (ORIF) of a fracture of the distal humerus.', 'Two independent observers evaluated 141 lateral radiographs of patients more than 6 months after fracture of the distal humerus and 155 lateral radiographs of patients without injury of the distal humerus. The distance between the most anterior point of the distal humerus articular surface, perpendicular to the humeral shaft, from the anterior border of the distal part of the humeral diaphysis, was measured on lateral radiographs as a percentage of the width of the humeral shaft.', 'The technique of measuring anterior translation of the distal humeral articular surface had good intra- and interobserver reliability. The most anterior point of the distal humeral articular surface lies an average of 11.7 mm (range, 6.8 to 17.0 mm) in front of the most anterior border of the humeral shaft in normal distal humeri, which represents 62% of the humeral shaft diameter (range, 33% to 91%). There was a limited but significant correlation between flexion and anterior translation as a percentage of the humeral shaft diameter in distal humeri after fracture that was maintained in multivariable statistical models.\Question: Is loss of anterior translation of the distal humeral articular surface associated with decreased elbow flexion?


Output: Using a reproducible technique for measuring anterior translation of the distal humerus, there was a correlation between anterior translation of the distal humeral articular surface and elbow flexion after ORIF. Although the weakness of the correlation emphasizes that limitation of elbow flexion after ORIF of a distal humerus fracture is multifactorial, reduced anterior translation of the distal humeral articular surface might be a contributing factor.
