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: Low back pain is common and originates in the sacroiliac (SI) joint in 15%-30% of cases. Traditional SI joint disruption/degenerative sacroiliitis treatments include nonoperative care or open SI joint fusion. To evaluate the usefulness of newly developed minimally-invasive technologies, the costs of traditional treatments must be better understood. We assessed the costs of nonoperative care for SI joint disruption to commercial payers in the United States (US).', 'A retrospective study of claim-level medical resource use and associated costs used the MarketScan® Commercial Claims and Encounters as well as Medicare Supplemental Databases of Truven Healthcare. Patients with a primary ICD-9-CM diagnosis code for SI joint disruption (720.2, 724.6, 739.4, 846.9, or 847.3), an initial date of diagnosis from January 1, 2005 to December 31, 2007 (index date), and continuous enrollment for ≥1 year before and 3 years after the index date were included. Claims attributable to SI joint disruption with a primary or secondary ICD-9-CM diagnosis code of 71x.xx, 72x.xx, 73x.xx, or 84x.xx were identified; the 3-year medical resource use-associated reimbursement and outpatient pain medication costs (measured in 2011 US dollars) were tabulated across practice settings. A subgroup analysis was performed among patients with lumbar spinal fusion.', 'The mean 3-year direct, attributable medical costs were $16,196 (standard deviation [SD] $28,592) per privately-insured patient (N=78,533). Among patients with lumbar spinal fusion (N=434), attributable 3-year mean costs were $91,720 (SD $75,502) per patient compared to $15,776 (SD $27,542) per patient among patients without lumbar spinal fusion (N=78,099). Overall, inpatient hospitalizations (19.4%), hospital outpatient visits and procedures (14.0%), and outpatient pain medications (9.6%) accounted for the largest proportion of costs. The estimated 3-year insurance payments attributable to SI joint disruption were $1.6 billion per 100,000 commercial payer beneficiaries.

Example Input: The lowest peak expiratory flow (PEF) over a week, expressed as a percentage of the highest PEF (Min%Max PEF) has been reported to be the index that most closely correlates with airway hyperresponsiveness (AHR) in asthmatics. However, both fluctuation of the airway caliber and airflow limitation are regarded as physiological properties of asthma closely related to AHR. An accurate index that shows the degree of AHR may be obtained by combining the index of airway lability with the parameters that represent airway caliber.', 'Ninety-two steroid-naive and twenty-eight steroid-treated asthmatic patients were enrolled. Using the physiological parameters obtained from spirometry and PEF monitoring, we investigated the indices which correlate accurately with airway responsiveness measured by the inhalation challenge test.', 'Although the methacholine threshold was related to all parameters that represent airway caliber and lability, Min%Max PEF had the strongest correlation with AHR. When Min%Max PEF was adjusted by the airway geometric factors, the normalization of Min%Max PEF with forced expiratory volume in one second as a percentage of the predicted value (%FEV(1)) improved the relationship between Min%Max PEF and AHR.

Example Input: Ginkgo biloba extract, EGb761, is one of the most commonly used herbal supplements throughout Western society. It has been used in the treatment of various common geriatric complaints including short-term memory loss. We showed that acute systemic administration of EGb761 enhanced fear-potentiated startle (FPS) in rats. Little is known about the behavioral effects of centrally administered EGb761 on FPS.', 'The current study was performed to evaluate the involvement of basolateral nucleus of amygdala (BLA) in the EGb761 facilitation effect on FPS.', "Male adult SD rats were used. EGb761 was infused into cerebroventricle or basolateral nucleus of amygdala 10 min prior to fear conditioning. Animals were then tested for FPS 24 h later. Results showed that (1) intra-cerebroventricular infusion of EGb761 (0.1, 1.0, or 3.0 microg/3.0 microl per side, bilaterally) and intra-amygdaloid infusion of EGb761 (1.0, 14.0, or 28.0 ng/microl per side, bilaterally) 30 and 10 min prior to fear conditioning, respectively, facilitated FPS in a dose-dependent manner. (2) Administration of EGb761 did not impair an animal's basal startle response or pain perception. (3) Subsequent control experiment's results indicated that the facilitation effect of EGb761 on the acquisition was not due to anxiogenic effect or non-specific effect.
