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: Chagas heart disease (CHD) patients may have a reduced functional capacity (FC). Field tests, as the Incremental Shuttle Walk Test (ISWT), can estimate peak oxygen uptake (VO2 peak). However, the relationship between the ISWT and the Cardiopulmonary Exercise Testing (CPET), the gold standard in the assessment of FC, is not well established in CHD patients.', 'This study aimed to evaluate the FC of CHD patients by ISWT with direct measurement of VO2 peak and to compare these findings with data obtained from CPET. A secondary goal was to derive a regression equation to calculate the VO2 peak by ISWT.', 'Cross-sectional and correlative study.', 'Research laboratory setting.', 'Thirty-two CHD patients (58.8±9.0 years, 81.3% women) participated in this study.', 'Eligible patients underwent clinical evaluation, echocardiography, CPET by ramp protocol and ISWT according to current guidelines.', 'The distance walked in ISWT showed a positive correlation with VO2 peak from CPET and ISWT (r=0.456, P=0.009 and r=0.869, P<0.001, respectively). In the agreement analysis, the values of the differences between VO2 peak from CPET and ISWT showed absence of bias (mean bias ±95% CI and mean -1.29±5.09 mL.kg.min). Based in real values of VO2 obtained from ISWT, one equation including sex, functional class and distance walked was provided to predict the VO2 values in this test.

Example Input: Spinally elicited peripheral nerve responses, commonly called neurogenic motor evoked potentials (NMEPs), are widely used to monitor spinal cord motor function during surgery. However, numerous evidence suggests that these responses are primarily sensory rather than motor. The collision technique was utilized to address this issue.', 'Collision studies were performed in 7 patients during surgery. An ascending volley of sensory (AS) and motor activity (AM) was elicited by posterior tibial nerve stimulation at the popliteal fossa. After a short time delay, high cervical spinal stimulation produced a descending volley of sensory (DS) and motor (DM) activity. The AM volley ascended only to the anterior horn cells whereas the AS and DS volleys collided in the spinal cord. The inter-stimulus delays were varied so as to affect the degree of spinal cord collision. The DS and DM activity which remained after collision was recorded from the posterior tibial nerves at the ankle.', 'Inter-stimulus delays of 18 ms or less resulted in no apparent peripheral descending volleys. These findings were consistent for all the patients studied.

Example Input: Inosine, a naturally occurring purine nucleoside, has been shown to stimulate axonal growth in cell culture and promote corticospinal tract axons to sprout collateral branches after stroke, spinal cord injury and TBI in rodent models.', 'To explore the effects of inosine on the recovery of motor function following cortical injury in the rhesus monkey.', 'After being trained on a test of fine motor function of the hand, monkeys received a lesion limited to the area of the hand representation in primary motor cortex. Beginning 24 hours after this injury and continuing daily thereafter, monkeys received orally administered inosine (500\u200amg) or placebo. Retesting of motor function began on the 14th day after injury and continued for 12 weeks.', 'During the first 14 days after surgery, there was evidence of significant recovery within the inosine-treated group on measures of fine motor function of the hand, measures of hand strength and digit flexion. While there was no effect of treatment on the time to retrieve a reward, the treated monkeys returned to asymptotic levels of grasp performance significantly faster than the untreated monkeys. Additionally, the treated monkeys evidenced a greater degree of recovery in terms of maturity of grasp pattern.
