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: Parasympathetic dysfunction is an independent risk factor for mortality in heart failure for which there is no specific pharmacologic treatment. This article aims to determine the effect of pyridostigmine, an anticholinesterase agent, on the integrated physiologic responses to dynamic exercise in heart failure.', 'Patients with chronic heart failure (n = 23; 9 female; age = 48 +/- 12 years) were submitted to 3 maximal cardiopulmonary exercise tests on treadmill in different days. The first test was used for adaptation and to determine exercise tolerance. The other tests were performed after oral administration of pyridostigmine (45 mg, 3 times/day, for 24 hours) or placebo, in random order. All patients were taking their usual medication. Pyridostigmine reduced cholinesterase activity by 30%, inhibited the chronotropic response throughout exercise, up to 60% of maximal effort (pyridostigmine = 108 +/- 3 beats/min vs. placebo = 113 +/- 3 beats/min; P = .040), and improved heart rate reserve (pyridostigmine = 73 +/- 5 beats/min vs. placebo = 69 +/- 5 beats/min; P = 0.035) and heart rate recovery in the first minute after exercise (pyridostigmine = 25 +/- 2 beats/min vs. placebo = 22 +/- 2 beats/min; P = .005), whereas peak heart rate was similar to placebo. Oxygen pulse, an indirect indicator of stroke volume, was higher under pyridostigmine during submaximal exercise.

Example Input: Advanced heart failure (HF) is associated with increased morbidity and mortality; traditionally used prognostic factors often fail to predict the outcome. Increased red blood cell distribution width (RDW) has recently been recognized as an important unfavorable prognostic factor in HF, independent of anemia; however, the role of RDW in patients with advanced HF has not yet been investigated.', 'Eighty consecutive patients with stage D heart failure, recently hospitalized for HF decompensation, were enrolled. A Cox proportional-hazard model was used to determine whether RDW was independently associated with outcome.', 'At study entry, ejection fraction (EF), pulmonary capillary wedge pressure (PCWP), hemoglobin (Hb) and RDW were 25 ± 8.6%, 27.5 ± 8 mmHg, 12.5 ± 1.9 mg/dL and 18 ± 3.5% (normal <14.5%) respectively. At 6 months, 44 patients (55%) had died. In this patient population, EF (p=0.45), PCWP (p=0.106), age (p=0.54), albumin (0.678), iron (p=0.37), creatinine (p=0.432), iron deficiency defined by bone marrow aspiration (p=0.37), bilirubin (p=0.422), peak VO2 (p=0.057) and Hb (p=0.95) were not significant predictors of a worse outcome. However, RDW was a significant marker for adverse prognosis (p=0.007, HR: 1.14, CI: 1.04-1.24) and retained its prognostic significance even when corrected for Hb values (HR: 1.15, CI: 1.05-1.27, p=0.003).

Example Input: The objective of the present study was to investigate the relationship between colorectal and prostate cancer.', 'All Victorian men who developed metachronous colorectal and prostate cancer with the first primary diagnosed between 1982 and 1993 were identified retrospectively from the Victorian Cancer Registry and were followed up to the end of 1995. Analyses were stratified by age group and years of follow up. The cause of death in those men who had prostate cancer following colorectal cancer was determined. The stage of colorectal cancer was compared between men with and without second primary prostate cancer and the grade of prostate cancer was compared with men who did not have a prior colorectal cancer.', 'Men who develop colorectal cancer are at increased risk of prostate cancer, with the greatest risk in men under the age of 65 (Relative risk approximately 2). Men with first primary colorectal cancer are more likely to develop prostate cancer than colorectal second primaries, and men who develop second primary prostate cancer are more likely to die of prostate cancer than colorectal cancer.
