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.

Input: Consider Input: Covert hepatic encephalopathy (CHE) is associated with cognitive dysfunction, which affects daily function and health-related quality of life (HRQOL) in patients with cirrhosis. The effects of CHE and liver disease are determined by cognitive reserve—the ability of the brain to cope with increasing damage while continuing to function—and are assessed by composite intelligence quotient (IQ) scores. We examined cognitive reserve as a determinant of HRQOL in patients with cirrhosis.', 'We performed a prospective study of 118 outpatients with cirrhosis without overt HE (age, 56 y). We studied cognition using the standard paper-pencil battery; patients with below-normal results for more than 2 tests were considered to have CHE. We also assessed HRQOL (using the sickness impact profile [SIP]), psychosocial and physical scores (a high score indicates reduced HRQOL), model for end-stage liver disease (MELD) scores, and cognitive reserve (using the Barona Index, a validated IQ analysis, based on age, race, education, residence area, and occupation). Cognitive reserve was divided into average and high groups (<109 or >109), and MELD and SIP scores were compared. We performed regression analyses, using total SIP score and psychosocial and physical dimensions as outcomes, with cognitive reserve, CHE, and MELD score as predictors.', 'Study participants had average MELD scores of 9, and 14 years of education; 81% were white, 63% were urban residents, their mean IQ was 108 ± 8, and 54% had average cognitive reserve (the remaining 46% had high reserves). CHE was diagnosed in 49% of patients. Cognitive reserve was lower in patients with CHE (109) than without (105; P = .02). Cognitive reserve correlated with total SIP and psychosocial score (both r = -0.4; P < .001) and physical score (r = -0.3; P = .01), but not MELD score (P = .8). Patients with high cognitive reserve had a better HRQOL, despite similar MELD scores. In regression analyses, cognitive reserve was a significant predictor of total SIP (P < .001), psychosocial (P < .001), and physical scores (P < .03), independent of CHE, MELD, or psychiatric disorders.

Input: Consider Input: A recent (123)I-FP-CIT ((123)-I-N-ω-fluoropropyl-2β-carbomethoxy-3β-(4-iodophenyl)nortropane) SPECT study on rats suggested that a single 1 mg/kg dose of the antipsychotic haloperidol induces enough dopamine release to compete with (123)I-FP-CIT for binding to the dopamine transporter. Taking into account the far-reaching consequences of this proposition, we were interested in testing whether we could reproduce this finding using storage phosphor imaging.', 'Twenty rats were pretreated with saline or haloperidol (1 mg/kg of body weight) and then injected with (123)I-FP-CIT. Two hours after (123)I-FP-CIT injection, the rats were sacrificed and binding in the striatum, nucleus accumbens, and cerebellum (nonspecific binding) was measured.', 'In contrast to the earlier SPECT finding, acute administration of haloperidol did not induce a significant change in (123)I-FP-CIT binding ratios in the striatum and nucleus accumbens.

Input: Consider Input: Mild hyperhomocysteinaemia (HHC) is associated with an increased risk of premature atherothrombotic cerebrovascular disease. We investigated the clinical efficacy with regard to the incidence of cardiovascular events of treatment of mild HHC with vitamin B(6) plus folic acid.', 'We studied 224 consecutive patients with clinically manifest atherothrombotic cerebrovascular disease with onset before the age of 56. Follow-up was obtained in 203 (90.6%) patients. At baseline, 52 (25.6%) were hyperhomocysteinaemic after methionine loading and started treatment with vitamin B(6) (250 mg) plus folic acid (5 mg); 151 (74.4%) were normohomocysteinaemic (reference group).', 'During follow-up (median 57 months), 31 (20.5%) of the normo- and 11 (21.2%) of the hyperhomocysteinaemic patients had a new cardiovascular event. The crude incidence rate per person-year for any cardiovascular event was similar in both groups (0.043 [CI, 0.029-0.057] in the normo- vs. 0.045 [CI, 0.021-0. 069] in the hyperhomocysteinaemic group). Multivariate Cox-regression analyses showed that hypertension and cholesterol levels were associated with an increased risk of new cardiovascular events in the total group [relative risk [RR] (yes vs. no), 7.4 (3. 4-16.0) and RR (per 1 mmol/l), 1.9 (CI, 1.4-2.7)]. The adjusted RR for new cardiovascular events in the hyper- as compared to the normohomocysteinaemic patients was 0.96 (CI, 0.48-1.92).
