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: Dilated cardiomyopathy (DCM) is a major cause of heart failure that may require heart transplantation. Approximately one third of DCM cases are familial. Next-generation DNA sequencing of large panels of candidate genes (ie, targeted sequencing) or of the whole exome can rapidly and economically identify pathogenic mutations in familial DCM.', 'We recruited 64 individuals from 26 DCM families followed at the Montreal Heart Institute Cardiovascular Genetic Center and sequenced the whole exome of 44 patients and 2 controls. Both affected and unaffected family members underwent genotyping for segregation analysis.', 'We found 2 truncating mutations in BAG3 in 4 DCM families (15%) and confirmed segregation with disease status by linkage (log of the odds [LOD] score = 3.8). BAG3 nonsense mutations conferred a worse prognosis as evidenced by a younger age of clinical onset (37 vs 48 years for carriers and noncarriers respectively; P = 0.037). We also found truncating mutations in TTN in 5 families (19%). Finally, we identified potential pathogenic mutations for 9 DCM families in 6 candidate genes (DSP, LMNA, MYH7, MYPN, RBM20, and TNNT2). We still need to confirm several of these mutations by segregation analysis.

Input: Consider Input: Organ/space surgical site infections (OSIs) constitute an important postoperative metric. We sought to assess the impact of a previously described air leak test (ALT) on the incidence of OSI following major hepatectomies.', 'A single-institution hepatobiliary database was queried for patients who underwent a major hepatectomy without biliary-enteric anastomosis between January 2009 and June 2015. Demographic, clinicopathologic, and intraoperative data-including application of ALT-were analyzed for associations with postoperative outcomes, including OSI, hospital length of stay (LOS), morbidity and mortality rates, and readmission rates.', 'Three hundred eighteen patients were identified who met inclusion criteria, of whom 210 had an ALT. ALT and non-ALT patients did not differ in most disease and treatment characteristics, except for higher rates of trisegmentectomy among ALT patients (53 vs. 34\xa0%, p\u2009=\u20090.002). ALT patients experienced lower rates of OSI and 90-day morbidity than non-ALT patients (5.2 vs. 13.0\xa0%, p\u2009=\u20090.015 and 24.8 vs. 40.7\xa0%, p\u2009=\u20090.003, respectively). In turn, OSI was the strongest independent predictor of longer LOS (OR\u2009=\u20094.89; 95\xa0% CI, 2.80-6.97) and higher rates of 30- (OR\u2009=\u200932.0; 95\xa0% CI, 10.9-93.8) and 45-day readmissions (OR\u2009=\u200929.4; 95\xa0% CI, 10.2-84.6).

Input: Consider Input: Tumor cell migration and diffuse infiltration into brain parenchyma are known causes of recurrence after treatment in glioblastoma (GBM), mediated in part by the interaction of glioma cells with the extracellular matrix, followed by degradation of matrix by tumor cell derived proteases, particularly the matrix metalloproteinases (MMP). Sevoflurane and thiopental are anesthetics commonly used in cancer surgery. However, their effect on the progression of glioma cells remains unclear. The aim of this study was to explore the role of these anesthetics on the migration and activity of MMP-2 in glioma cells.', 'Cultured U87MG cells were pretreated with sevoflurane or thiopental and in vitro wound healing scratch assay was carried out to analyze their effect on migration of these cells. Gelatin zymography was carried out to examine the effect of these anesthetics on tumor cell MMP-2 activity using the conditioned media 24 h after pretreatment. Cell viability was analyzed using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay.', 'U87MG cells exposed to 2.5% sevoflurane or different concentrations of thiopental significantly decreased migration and activity of MMP-2 compared to control. No effect was seen on the viability of these cells after pretreatment with sevoflurane or thiopental.
