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.

[EX Q]: Advances in imaging technology have enhanced the detection of small nodular lesions during the course of chronic liver disease.', 'Between 1995 and 2002, the authors examined 154 consecutive patients with small hepatic nodules without hepatocellular carcinoma (HCC) over a median duration of 2.8 years. The median size of these nodules was 14 mm (range, 7-40 mm). The initial histopathologic diagnosis included high-grade dysplastic nodule (HGDN) (n=13), low-grade dysplastic nodule (LGDN) (n=42), and regenerative nodule (RN) (n=99).', 'A total of 29 (18.8%) nodules developed into HCC during the observation period. Cumulative HCC development rates at the first, third, and fifth year were 46.2%, 61.5%, and 80.8% for HGDN; 2.6%, 30.2%, and 36.6% for LGDN; and 3.3%, 9.7%, and 12.4% for RN, respectively. The rate of HCC development was significantly higher in the HGDN group than for other types (P<0.001). Multivariate analysis disclosed that histopathologic diagnosis (P<0.001) and findings on computed tomographic arterial portography (CT-AP) (P=0.004) were significantly associated with future HCC development. The hazard ratios of HGDN and LGDN were 16.8 (95% confidence interval [CI], 6.19-45.6) and 2.96 (95% CI, 1.20-7.31), respectively. A decrease in portal blood flow also showed a significantly high hazard ratio of 3.04 (95% CI, 1.42-6.50). Approximate annual development rate to HCC was 20% in patients with HGDN and 10% in LGDN.

[EX Q]: To report 4 patients with Avellino corneal dystrophy (ACD) who were treated with 0.02% mitomycin C (MMC) during phototherapeutic keratectomy (PTK).', 'ACD was confirmed by polymorphism of the exon region in the BIGH3 gene using polymerase chain reaction followed by DNA sequencing analysis. Three patients with recurrent ACD and 1 patient with primary ACD underwent PTK. Intraoperative 0.02% MMC was applied topically with a soaked microsponge.', 'There was no recurrence of ACD in the heterozygotes, but there were recurrences with best-corrected visual acuity of 20/30 in the 2 homozygotes.

[EX Q]: Comatose patients resuscitated after out-of-hospital cardiac arrest receive therapeutic hypothermia. Bradycardia is frequent during therapeutic hypothermia, but its impact on outcome remains unclear. We explore a possible association between bradycardia during therapeutic hypothermia and neurologic outcome in comatose survivors of out-of-hospital cardiac arrest.', 'Retrospective cohort study, from January 2009 to January 2011.', 'University hospital medical and cardiac ICUs.', 'One hundred eleven consecutive comatose out-of-hospital cardiac arrest patients treated with therapeutic hypothermia.', 'Patients treated with standardized treatment protocol after cardiac arrest.', "All out-of-hospital cardiac arrest patients' records were reviewed. Hemodynamic data were obtained every fourth hour during the first days. The patients were in temperature target range (32-34°C) 8 hours after out-of-hospital cardiac arrest and dichotomized into bradycardia and nonbradycardia groups depending on their actual heart rate less than or equal to 60 beats/min or more than 60 beats/min at that time. Primary endpoint was Cerebral Performance Category score at hospital discharge. More nonbradycardia group patients received epinephrine during resuscitation and epinephrine and norepinephrine in the early in-hospital period. They also had lower base excess at admission. Survival rate with favorable outcome was significantly higher in the bradycardia than the nonbradycardia group (60% vs 37%, respectively, p = 0.03). For further heart rate quantification, patients were divided into quartiles: less than or equal to 49 beats/min, 50-63 beats/min, 64-77 beats/min, and more than or equal to 78 beats/min, with respective proportions of patients with good outcome at discharge of 18 of 27 (67%), 14 of 25 (56%), 12 of 28 (43%), and 7 of 27 (26%) (p = 0.002). Patients in the lowest quartile had significantly better outcome than the higher groups (p = 0.027), whereas patients in the highest quartile had significantly worse outcome than the lower three groups (p = 0.013).
