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: In dialysis patients, volume overhydration is common and is related to increased risk of cardiovascular morbidity and mortality. However, it remains unclear whether volume overload imposes those detrimental effects through endothelial dysfunction.', 'In this cross-sectional study, 81 stable patients on continuous ambulatory peritoneal dialysis in a single center were recruited. Volume status was evaluated by extracellular water, assessed by bioimpedance analysis, and normalized to individual height (nECW). Endothelial function was estimated by endothelial-dependent flow-mediated dilatation (FMD) of the brachial artery and expressed as percentage change relative to baseline diameter.', 'There were 37 male and 44 female patients (mean age 61 +/- 12 years, dialysis vintage 20 +/- 23 months). FMD in female patients was significantly higher than that in male patients (9.17% +/- 6.23% vs 6.31% +/- 5.01%, p < 0.05). FMD was negatively correlated with weight (r = -0.308, p < 0.01), body mass index (r = -0.242, p < 0.05), systolic blood pressure (r = -0.228, p < 0.05), ECW (r = -0.404, p < 0.001), and nECW (r = -0.418, p < 0.001). No correlation was found between FMD and other variables. In multiple stepwise regression analysis, calcium x phosphate product (beta = 0.422, p < 0.001), nECW (beta = -0.343, p < 0.01), and dialysis vintage (beta = -0.237, p < 0.05) were independent determinants of FMD (adjusted R(2) = 0.327 for this model).

Example Input: Accurate prediction of recovery of dysfunctional myocardium would optimize risk/benefit analysis among patients with coronary artery disease and decreased ventricular function. Tissue-tagged magnetic resonance imaging permits quantitative assessment of changes in ventricular function and may improve the prediction of myocardial recovery after coronary artery bypass grafting.', 'Thirteen patients underwent preoperative and postoperative stress magnetic resonance imaging with strain analysis at rest with 5 and 10 microg x kg(-1) x min(-1) dobutamine. Two-dimensional strain analysis was performed on a single midventricular short-axis image divided into 6 regions for each patient (n = 78). Regional minimum principal, circumferential, and radial strain values were calculated at each stress level. Regional changes in postoperative strain were correlated with changes in preoperative dobutamine stress by means of logistic regression. Receiver operating characteristic curves were created to determine the accuracy of preoperative dobutamine stress for the prediction of postoperative myocardial recoverability.', 'Minimum principal, circumferential, and radial strain values at 5 and 10 microg of dobutamine differed significantly from baseline strains (P < .05). Receiver operator characteristic curves found minimum principal strain to be 75% accurate for prediction of recoverability at both stress levels. Circumferential strain was 72% and 70% accurate at 5 and 10 microg, respectively, whereas radial strain was 77% and 64% accurate at 5 and 10 microg, respectively.

Example Input: Irinotecan (CPT-11), a highly effective chemotherapeutic agent, can cause severe neutropenia and diarrhea. The area under the curve of plasma levels over time of SN-38, an active metabolite of CPT-11, was previously reported to correlate with the pre-treatment serum total bilirubin level (PTB). However, there are no established criteria for selecting CPT-11 dose on the basis of PTB. Therefore, we evaluated PTB as an indicator for the optimal CPT-11 dose.', 'Retrospective analyses were conducted in patients administered CPT-11 as a single agent at the Osaka National Hospital from June 2006 to July 2013. Data obtained during the first 28 days following CPT-11 administration were analyzed to compare PTB between patients with and without grade 3-4 neutropenia and grade 3-4 diarrhea. Receiver operating characteristics (ROC) curve analysis was performed to determine the optimal PTB cutoff value for PTB-associated toxicity. Subgroup analysis was performed comparing the incidence of toxicity in patients with PTB values below or above the cutoff value.', 'Although PTB incidence was significantly higher in patients who developed grade 3-4 neutropenia than in those who did not, PTB was not associated with grade 3-4 diarrhea. The PTB cutoff value for association with grade 3-4 neutropenia occurrence was set at 0.8 mg/dL. The incidence of febrile neutropenia (FN) significantly elevated to 21% in patients with PTB 0.8 mg/dL, whereas that of patients with PTB <0.8 mg/dL was 4%. In the subgroup analysis, no difference was found in the neutropenia incidence between patients treated with a dose below 80 mg/m(2) and those treated on a weekly schedule.
