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.

[Q]: To determine the associations between serum cortisol and HDL cholesterol, other lipoprotein lipids and cardiovascular risk factors, carotid atherosclerosis, and clinical heart disease in older people.', 'A cross-sectional, observational, ancillary study of the Cardiovascular Health Study (CHS).', 'A total of 245 community-dwelling people, 65 to 89 years old, were recruited consecutively for a 2-month period from the CHS cohort in Forsyth County, North Carolina.', 'Cortisol was measured by radioimmunoassay in serum collected between 7:00 and 10:00 AM after an overnight fast. Cortisol levels were correlated with lipoprotein lipids, insulin, glucose, body mass index, waist-hip ratio, prevalent coronary heart disease, hypertension, diabetes, and carotid atherosclerosis by B-mode ultrasound.', 'Serum cortisol was correlated negatively (r = -.24) with body mass index and waist-hip ratio (r = -.16) but was not related significantly to fasting insulin or glucose. Cortisol was not associated significantly with triglyceride and low density lipoprotein cholesterol but showed a positive correlation (r = .21) with high density lipoprotein cholesterol. The relationship between cortisol and high density lipoprotein cholesterol persisted after adjustment for gender, body mass index, waist-hip ratio, cigarette and alcohol use, triglyceride level, and diabetes. There was a trend toward a negative correlation between cortisol and measures of carotid atherosclerosis, but no significant relationship was indicated between cortisol and prevalent coronary heart disease, hypertension, or diabetes.

[Q]: Anxiety disorders increase risk of future cardiovascular disease (CVD) and mortality, even after controlling for confounds including smoking, lifestyle, and socioeconomic status, and irrespective of a history of medical disorders. While impaired vagal function, indicated by reductions in heart rate variability (HRV), may be one mechanism linking anxiety disorders to CVD, prior studies have reported inconsistent findings highlighting the need for meta-analysis.', 'Studies comparing resting-state HRV recordings in patients with an anxiety disorder as a primary diagnosis and healthy controls were considered for meta-analysis.', "Meta-analyses were based on 36 articles, including 2086 patients with an anxiety disorder and 2294 controls. Overall, anxiety disorders were characterized by lower HRV [high frequency (HF): Hedges' g=-0.29. 95% CI: -0.41 to -0.17, p<0.001; time domain: Hedges' g=-0.45, 95% CI: -0.57 to -0.33, p<0.001] than controls. Panic disorder (n=447), post-traumatic stress disorder (n=192), generalized anxiety disorder (n=68), and social anxiety disorder (n=90), but not obsessive-compulsive disorder (n=40), displayed reductions in HF HRV relative to controls (all ps<0.001).

[Q]: We tested the hypothesis that propofol, acting in the brain, would either enhance, or have no effect, on lumbar dorsal horn neuronal responses to a noxious mechanical stimulus applied to the hindlimb. We recorded the response of lumbar dorsal horn neurons during differential delivery of propofol to the brain and torso of goats.', 'Goats were anesthetized with isoflurane and neck dissections performed which permitted cranial bypass. A laminectomy was made to allow microelectrode recording of lumbar dorsal horn neuronal activity. Isoflurane was maintained at 0.8+/-0.1% to both head and torso throughout the study. During cranial bypass propofol was separately administered to the torso (1 mg x kg(-1), n = 7; 3.75 mg x kg(-1), n = 8) or cranial (0.04 mg x kg(-1), n = 7; 0.14 mg kg(-1), n = 8) circulations.', 'Propofol administered to the torso depressed dorsal horn neuronal responses to noxious stimulation: low dose: 500+/-243 to 174+/-240 impulses x min(-1) at one minute post-injection, P<0.001; high dose: 478+/-204 to 91+/-138 impulses x min(-1) at one minute post-injection, P<0.05). Propofol administered to the cranial circulation had no effect: low dose: 315+/-150 to 410+/-272 impulses x min(-1), P>0.05; high dose: 462+/-261 to 371+/-196 impulses x min(-1), P>0.05.
