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.

Input: Consider Input: Progression of pulmonary vascular disease limits heart transplantation for hypoplastic left heart syndrome (HLHS) to early infancy. Our objective was to assess the impact of bilateral pulmonary artery banding (PAB) on the operative courses of HLHS infants transplanted at ages older than 4 months.', 'Courses of all HLHS patients in our center who remained listed to age >or=120 days before heart transplantation were assessed. Patients undergoing transplantation after standard management (control group) were compared to patients having a prior pulmonary blood flow limiting procedure (PAB group).', 'Of 16 identified patients, one crossed over to stage I Norwood on day 185 and died post-operatively. Fifteen patients were transplanted at age >or=120 days (control group n=9, PAB group n=6). Four PAB patients had open PA band placement. Two PAB patients underwent experimental percutaneous bilateral internal pulmonary artery flow limiting device insertion. The PAB group mean age at banding was 141+/-54 days, and mean interval from PAB to transplant was 35+/-31 days (range 1.5-68 days). No differences in age at transplant, weight at transplant, warm graft ischemia time or total graft ischemia time were detected between groups. Mean times of mechanical ventilation (control 143+/-69h vs. PAB 44+/-13h), inhaled nitric oxide (control 126+/-70h vs. PAB 37+/-9h), inotropic support (control 171+/-64h vs. PAB 87+/-17h), intensive care unit (ICU) stay (control 8.3+/-2.7 days vs. PAB 4.5+/-1.4 days), and hospital stay (control 10.4+/-3.9 days vs. PAB 7.0+/-1.1 days) were all lower in the PAB group (P<0.05 all comparisons). Two control patients died, three required extracorporeal membrane oxygenation (ECMO), and six did not tolerate primary chest closure. No PAB patient died or required ECMO. All PAB patients tolerated primary chest closure. All PAB patients had widely patent branch pulmonary arteries with no re-interventions to date. All hospital survivors remain alive (mean follow-up, control 50.2 months, PAB 11.5 months).

Input: Consider Input: Video-EEG monitoring in the epilepsy monitoring unit (EMU) is a limited clinical resource. Knowledge of the predicting factors for length of stay (LOS) in the EMU may allow providers to more efficiently utilize EMU bed space.', 'The records for all consecutive admissions to the EMU at the University of Colorado Hospital between December 1, 2010 and May 31, 2011 (n = 142) were retrospectively reviewed.', 'Univariate analyses focusing on variables known prior to admission showed that EMU LOS (in hours) was not significantly correlated with patient age, number of event types, or number of antiepileptic drugs at admission. Patients who were admitted to the EMU for event characterization had statistically significantly shorter average LOS than patients who had been admitted as a part of a presurgical evaluation. Patients who reported < = 1 seizure per week had a statistically significantly higher average LOS than patients who reported >= 1 seizure per day. These variables were also significantly predictive of total LOS (p < 0.0001 and p = 0.03, respectively) in multivariate analysis.

Input: Consider Input: To investigate the eff ect of intestinal trefoil factor (ITF) on the transcriptional activity of ITF promoter and to explore the regulatory mechanism of Janus kinase/signal transducers and activators of transcription (JAK/STAT) on ITF promoter.', "The 5' flanking sequence of the ITF gene was cloned from human whole blood genomic DNA by PCR. ITF promoter fragment was cloned and inserted into the pGL3-Basic vector to construct recombinant vector. ITF promoter vector was stimulated with ITF at various concentrations and the luciferase activity was measured. The JAK-STAT3 signal transduction pathway was then blocked by a specific inhibitor AG490 to determine the signal pathway involved in ITF promoter activity.", 'Restriction endonuclease analysis and DNA sequencing confirmed that the recombinant plasmid, containing ITF promoter, was constructed successfully. After transient transfection, the activity of ITF promoter was increased significantly in the presence of ITF (P<0.05). Blockage of the JAK-STAT3 signal transduction pathway with AG490 significantly reduced the ITF promoter activity (P<0.05).
