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.
question:
In heart failure, a holistic approach incorporating the patient's perspective is vital for prognosis and treatment. Self-rated health has strong associations with adverse events and short-term mortality risk, but long-term data are limited. We investigated the predictive value of two consecutive self-rated health assessments with regard to long-term mortality in a large, well characterised sample of elderly patients with stable chronic heart failure.", "We measured self-rated health by asking 'In general, would you say your health is: 1, excellent; 2, very good; 3, good; 4, fair; 5, poor?' twice: at baseline and the end of a 12-week beta-blocker up-titration period in the CIBIS-ELD trial. Mortality was assessed in an observational follow-up after 2-4 years. A total of 720 patients (mean left ventricular ejection fraction 45±12%, mean age 73±5 years, 36% women) rated their health at both time points. During long-term follow-up, 144 patients died (all-cause mortality 20%). Fair/poor self-rated health in at least one of the two reports was associated with increased mortality (hazard ratio 1.42 per level; 95% confidence interval 1.16-1.75; P<0.001). It remained independently significant in multiple Cox regression analysis, adjusted for N-terminal pro B-type natriuretic peptide (NTproBNP), heart rate and other risk prediction covariates. Self-rated health by one level worse was as predictive for mortality as a 1.9-fold increase in NTproBNP.

question:
We sought to determine the association between low caregiver health literacy and child emergency department (ED) use, both the number and urgency of ED visits.', 'This year long cross-sectional study utilized the Newest Vital Sign questionnaire to measure the health literacy of caregivers accompanying children to a pediatric ED. Prior ED visits were extracted from a regional database. ED visit urgency was classified by resources utilized during the index ED visit. Regression analyses were used to model 2 outcomes-prior ED visits and ED visit urgency-stratified by chronic illness. Analyses were weighted by triage level.', 'Overall, 503 caregivers completed the study; 55% demonstrated low health literacy. Children of caregivers with low health literacy had more prior ED visits (adjusted incidence rate ratio 1.5; 95% confidence interval 1.2, 1.8) and increased odds of a nonurgent index ED visit (adjusted odds ratio 2.4; 95% confidence interval 1.3, 4.4). Among children without chronic illness, low caregiver health literacy was associated with an increased proportion of nonurgent index ED visits (48% vs. 22%; adjusted odds ratio 3.2; 1.8, 5.7).

question:
Myocardial electrical impedance (MEI) has shown to be an effective indicator of myocardial ischemia. We have previously developed a novel monitor for measuring MEI in near-real time. The object of this study was to test whether drug-induced changes in the frequency of the periodic myocardial electrical activity, as measured by the heart rate (HR), affect MEI measurements made with our monitor.', 'Thirty dogs were randomly assigned to one of three study groups (placebo, isoproterenol or esmolol) and then anesthetized with sodium thiamylal, intubated, ventilated, given isoflurane, and had venous, arterial, and pulmonary artery catheters placed. Median sternotomy was performed to facilitate myocardial exposure and to allow the left anterior descending (LAD) coronary artery to be isolated. Following baseline measurements, saline (control), isoproterenol or esmolol was administered and the LAD coronary artery was occluded in a timed sequence in order to study the effects of heart rate changes and demonstrate induced myocardial ischemia on MEI.', 'Isoproterenol raised the HR and esmolol lowered the HR without affecting our MEI measurements. Myocardial electrical impedance increased during LAD coronary artery occlusion in all groups, as previously shown.
