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]: It is often suggested that immigrants with long-term pain do not benefit from rehabilitation to the same extent as native Swedish patients. In this study, an 8-week rehabilitation programme was evaluated according to its adaptation for immigrants.', "To establish whether there is a difference between immigrants and native Swedes concerning: (i) return-to-work, the patients' own estimation and their actual ability; (ii) higher level of activity; (iii) reduction in pain and analgesic use.", 'A total of 67 patients with persistent non-malignant pain completed the rehabilitation programme. Thirty (45%) of the patients were immigrants.', 'A 1- and a 3-year follow-up were made to compare the outcome between the 2 groups.', "There was no significant difference in the return-to-work rate between immigrants and native Swedes. However, the patients' prediction of their ability to return to work was higher among the non-immigrants. The level of activity was lower and pain intensity and use of analgesics were higher among the immigrants than the non-immigrants.

[EX Q]: Patients with frequent premature ventricular complexes (PVCs) might be at risk for the developing or exacerbation of left ventricular (LV) dysfunction. However, some patients with a high-PVC burden do not develop cardiomyopathy, while other patients with low-PVC burden can develop cardiomyopathy. The purpose of this study was to evaluate the positive predictors of idiopathic PVCs-induced cardiomyopathy.', 'We investigated 214 patients undergoing successful ablation of PVCs who had no other causes of cardiomyopathy. We divided the study cohort into 2 groups: ejection fraction (EF) ≥ 50% (normal LV) and EF < 50% (LV dysfunction). We analyzed the clinical characteristics, including the electrocardiogram and findings at electrophysiology study. Among these patients, 51 (24%) had reduced LVEF and 163 (76%) had normal LV function. Patients with LV dysfunction had significantly longer coupling interval (CI) dispersion (maximum-CI-minimum-CI) and had significantly higher PVC burden compared to those with normal LV function (CI-dispersion: 115 ± 25 milliseconds vs. 94 ± 19 milliseconds; P < 0.001; PVC burden: 19% vs. 15%; P = 0.04). Furthermore, patients with LV dysfunction had significantly higher body mass index (BMI) compared to those with normal LV function (BMI > 30 kg/m(2) ; 37% vs. 13%; P = 0.001). Logistic regression analysis showed that CI-dispersion, PVC burden, and BMI (>30\xa0kg/m(2) ) are independent predictors of PVC-induced cardiomyopathy.

[EX Q]: Most hepatocellular carcinomas (HCCs) are associated with cirrhosis. Portal hypertension (PHT) and esophageal variceal bleeding (EVB) can limit the patient's treatment options. Surgical therapy in such patients is challenging. We performed devascularization plus liver resection or radiofrequency ablation (RFA) to treat HCC patients with concomitant EVB resulting from PHT secondary to cirrhosis. Such combined operations have never been reported for the management of HCC patients with variceal esophageal bleeding.", 'To evaluate two different treatment regimens for patients with HCC and EVB.', 'We evaluated 35 BCLC stage 0/A patients with HCC and EVB who underwent either devascularization plus liver resection (Group A) or devascularization plus RFA (Group B). We reviewed the safety and outcomes of the two groups and assessed risk factors for patient survival and tumor recurrence.', 'Significant factors for overall survival were surgical approach and Child-Pugh classification. Child-Pugh classification was the only independent risk factor for overall postoperative survival [hazard ratio (HR) 8.320, 95 % confidence interval (CI) 1.739-39.799, P = 0.008]. Age was the only independent risk factor for tumor recurrence (HR 4.025, 95 % CI 1.343-12.062, P = 0.013).
