Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Example Input: Because of greater recognition and improved imaging capabilities, intraductal papillary mucinous neoplasms (IPMNs) are being diagnosed with increasing frequency. IPMNs of the main pancreatic duct cause symptoms and lead to pancreatitis. Side-branch (SB) IPMNs are thought to cause symptoms less frequently, and their association with pancreatitis is not well defined.', 'Our purpose was to ascertain whether an association exists between SB-IPMN and pancreatitis.', 'Single-center, retrospective study.', 'Academic medical center.', 'A total of 305 patients underwent EUS examinations between October 2002 and October 2006 for pancreatic cystic lesions.', 'The main outcome measure was the frequency of acute or chronic pancreatitis that was not procedurally related.', 'Thirty-two patients had SB-IPMNs, and 11 (34%) had pancreatitis. Three patients reported a single episode, and 8 patients reported having recurrent episodes of pancreatitis. Overall, 17 (53%) patients had symptoms possibly attributable to SB-IPMN. Female sex (73% vs 38%) and multiple pancreatic lesions (54% vs 24%) were more commonly seen in those with pancreatitis, but were not statistically significant factors. Larger cyst size or cyst fluid marker levels did not appear associated with pancreatitis occurrence. EUS-FNA demonstrated communication with the pancreatic duct in 94% and thick, mucinous fluid in 84%.

Example Input: Efavirenz is used for the antiretroviral treatment of HIV/tuberculosis-coinfected patients in developing countries. A switch to nevirapine is regularly carried out because of the cost and side effects of efavirenz. Pharmacokinetic studies suggested that nevirapine should be initiated at full dose when used as a substitute for efavirenz.', 'The aim of this study was to measure the cumulative incidence of adverse events (AEs) related to nevirapine in patients switched from efavirenz to immediate full-dose nevirapine (FDN).', 'In 2001 an antiretroviral treatment programme was initiated with the first-line regimen stavudine, lamivudine and efavirenz. In 2003, the fixed-dose combination of stavudine, lamivudine and nevirapine was recommended. Thus, first-line therapy was changed and FDN was initiated when patients were switched from efavirenz to nevirapine.', 'Between April and December 2004, 394 patients were switched from efavirenz to FDN. The cumulative incidence of AEs related to nevirapine was 13.2% [95% confidence interval (CI) 10.2-16.7] and that of severe AEs was 8.9% (95% CI 6.5-11.9). In women the incidence of AEs was 17.6% (95% CI 12.1-24.3) and that of severe AEs was 12.2% (95% CI 7.7-18.2).

Example Input: We examined the use of occupational therapy services in a sample of people aging with multiple sclerosis (MS).', 'A total of 1,282 people with MS, ages 45 to 90, participated in telephone interviews to identify unmet health-related service needs. Occupational therapy was 1 of 22 services examined. Proportional odds models were used to examine factors associated with how recently services were used.', 'Four hundred eighty-four participants (38.2%) had used occupational therapy services at some point since their diagnosis; 211 had used these services in the year before the interview. Recent users identified occupational therapy services as important to health and well-being. Satisfaction with services was high. Greater activity limitations and living in an urban or suburban area were associated with more recent use of occupational therapy services.
