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.

[Q]: There have seen several studies evaluating the efficacy of anti-tumor necrosis factor α (anti-TNFα) compared with conventional therapy (i.e. immunomodulators, mesalamine, or placebo) at preventing postoperative Crohn's disease (CD) recurrence. The results of these studies have been variable and the magnitude by which anti-TNFα therapy alters the natural history of CD in the postoperative setting has not yet been fully defined.", 'A comprehensive search of PubMed/MEDLINE, Scopus, CINAHL, and Cochrane databases was performed (May 2014). All studies on adult patients with CD that compared anti-TNFα therapy versus conventional therapy or placebo to prevent CD recurrence were included. Meta-analysis was performed using the Mantel-Haenszel (fixed effects) model with odds ratio (OR) to assess for clinical remission.', 'In the pooled analysis, there was a higher frequency of achieving clinical remission beyond 1 year from time of surgery among patients receiving anti-TNFα therapy compared with conventional therapy [OR 6.41; 95% confidence interval (CI) 2.88-14.27]. There was also a significantly higher rate of achieving both endoscopic (OR 26.44; 95% CI 10.48-66.68) and histologic remission (OR 9.80; 95% CI 2.54-37.81) in the anti-TNFα therapy group compared with the conventional therapy group.

[Q]: THE AIM OF THE STUDY WAS: Is primary Arterio-venous fistula the vascular access of choice for adequate dialysis and better patient outcome in end stage renal disease.', 'The present study was done in the department of cardiovascular and thoracic surgery at Sher-i-Kashmir institute of medical sciences, Soura, Srinagar Kashmir. Native Arterio-Venous (AV) fistulas were made in the patients with end stage renal disease for performing hemodialysis. They were followed for patency and adequacy of blood flow during hemodialysis. All the patients were operated under local anesthesia.', 'The results showed that 77% of the AV fistulas based on radial artery with side-to-side anastomosis and 80% of those with end-to-side anastomosis were functionally patent after one year. After two years, the patency rate in side-to-side and end-to-side anastomosis was 50% and 55%, respectively. In addition, the patency rate was 90% in brachial artery based AV fistula with end-to-side anastomosis, whether done primarily or secondarily, at the end of one year. However, a rapid decline was observed in the patency rate during the third year in both radial artery based and brachial artery based AV fistulas.

[Q]: Expression of truncated G-CSFR forms in patients with SCN/AML induces hyperproliferation and prolonged cell survival. Previously, we showed that ligand internalization is delayed and degradation of truncated G-CSFR forms is defective in patients with SCN/AML.', 'In this study, we investigated the potential roles of dileucine and tyrosine-based motifs within the cytoplasmic domain of the G-CSFR in modulating ligand/receptor internalization. Using standard binding assays with radiolabeled ligand and COS-7 cells, substitutions in the dileucine motif or deletion of tyrosine residues in the G-CSFR did not alter internalization. Attachment of the transferrin receptor YTRF internalization motif to a truncated G-CSFR form from a patient with SCN/AML corrected defective internalization, but not receptor degradation suggesting that receptor internalization and degradation occur independently via distinct domains and/or processes.
