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.

[EX Q]: Efavirenz is used for the antiretroviral treatment of HIV/tuberculosis-coinfected patients in developing countries. A switch to nevirapine is regularly carried out because of the cost and side effects of efavirenz. Pharmacokinetic studies suggested that nevirapine should be initiated at full dose when used as a substitute for efavirenz.', 'The aim of this study was to measure the cumulative incidence of adverse events (AEs) related to nevirapine in patients switched from efavirenz to immediate full-dose nevirapine (FDN).', 'In 2001 an antiretroviral treatment programme was initiated with the first-line regimen stavudine, lamivudine and efavirenz. In 2003, the fixed-dose combination of stavudine, lamivudine and nevirapine was recommended. Thus, first-line therapy was changed and FDN was initiated when patients were switched from efavirenz to nevirapine.', 'Between April and December 2004, 394 patients were switched from efavirenz to FDN. The cumulative incidence of AEs related to nevirapine was 13.2% [95% confidence interval (CI) 10.2-16.7] and that of severe AEs was 8.9% (95% CI 6.5-11.9). In women the incidence of AEs was 17.6% (95% CI 12.1-24.3) and that of severe AEs was 12.2% (95% CI 7.7-18.2).

[EX Q]: Imitation, which is impaired in children with autism spectrum disorder (ASD) and critically depends on the integration of visual input with motor output, likely impacts both motor and social skill acquisition in children with ASD; however, it is unclear what brain mechanisms contribute to this impairment. Children with ASD also exhibit what appears to be an ASD-specific bias against using visual feedback during motor learning. Does the temporal congruity of intrinsic activity, or functional connectivity, between motor and visual brain regions contribute to ASD-associated deficits in imitation, motor, and social skills?', 'We acquired resting-state functional magnetic resonance imaging scans from 100 8- to 12-year-old children (50 ASD). Group independent component analysis was used to estimate functional connectivity between visual and motor systems. Brain-behavior relationships were assessed by regressing functional connectivity measures with social deficit severity, imitation, and gesture performance scores.', 'We observed increased intrinsic asynchrony between visual and motor systems in children with ASD and replicated this finding in an independent sample from the Autism Brain Imaging Data Exchange. Moreover, children with more out-of-sync intrinsic visual-motor activity displayed more severe autistic traits, while children with greater intrinsic visual-motor synchrony were better imitators.

[EX Q]: Patients with obstructive sleep apnea (OSA) and coronary artery disease have a poor long-term prognosis. It is unknown whether the coronary blood flow (CBF) response to OSA is appropriate for myocardial metabolic requirements. Therefore, CBF was assessed during OSA, before and after the development of coronary artery endothelial dysfunction.', 'University Hospital Animal Laboratory.', 'Newborn lambs.', 'Lambs were surgically instrumented for invasive hemodynamic monitoring and sleep-wake EEG recordings. A tracheostomy was inserted to control the upper airway and model OSA during sleep. Coronary artery endothelial dysfunction was created using infusions of lipopolysaccharide (LPS). The CBF response during OSA was assessed and compared to changes in myocardial work (rate-pressure product [RPP]), O2 saturation, and cortical arousal, before and after the LPS infusions.', 'During OSA, CBF increased by 8.6% +/- 2.4% above baseline in the pre-LPS condition and 8.8% +/- 1.9% post-LPS, peaking following termination of the respiratory event. Pre-LPS, change in CBF post-apnea was independently correlated with change in RPP (R2 = 0.50), minimum SpO2 (R2 = 0.11) and the presence of cortical arousal (R2 = 0.04) (P < 0.01, forward stepwise regression analysis). Following LPS, the only predictor of CBF was degree of O2 desaturation (R2 = 0.14, P < 0.05).
