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: To investigate if diabetic patients without diabetic retinopathy despite long disease duration have different human leukocyte antigen (HLA) status vs those with an early onset of retinopathy.', 'Retrospective, nonrandomized, masked comparative study. Type 1 diabetic patients with a disease onset before age 30 were recruited to the study. The study population consisted of two groups of diabetic patients: those with normal retinopathy course (retinopathy developed during the first 20 years of diabetes onset) (23 patients) and those with postponed retinopathy (no obvious retinopathy in spite of passing 20 years of diabetes) (19 patients). These groups were matched with regard to level of glycemic control, blood pressure, and lipid profile. A group of 23 healthy patients served as controls. HLA-DQB1 typing of blood samples was done using a polymerase chain reaction with sequence-specific primer (PCR-SSP) method.', 'HLA-DQB1*0201/HLA-DQB1*0501 and HLA-DQB1*0201/HLA-DQB1*0504 haplotypes were more common among type 1 diabetic patients with normal retinopathy course than those with postponed retinopathy (26.1% vs 0.0%; p=0.019). HLA-DQB1*0301 and HLA-DQB1*0304 were less common among those diabetic patients with normal retinopathy course than those with a postponed retinopathy (63.2% vs 34.8%; p=0.067).

Input: Consider Input: We designed and tested an innovative transitional care program, involving cardiac surgery nurse practitioners, to improve care continuity after patient discharge home from coronary artery bypass graft (CABG) operations and decrease the composite end point of 30-day readmission and death.', 'A total of 401 consecutive CABG patients were eligible between May 1, 2010, and August 31, 2011, for analysis. Patient data were entered prospectively into The Society of Thoracic Surgeons database and the New York State Cardiac Surgery Reporting System and retrospectively analyzed with Institutional Review Board approval. The "Follow Your Heart" program enrolled 169 patients, and 232 controls received usual care. Univariate and multivariate analyses were used to identify readmission predictors, and propensity score matching was performed with 13 covariates.', 'Binary logistic regression analysis identified "Follow Your Heart" as the only independently significant variable in preventing the composite outcome (p=0.015). Odds ratios for readmission were 3.11 for dialysis patients, 2.17 for Medicaid recipients, 1.87 for women, 1.86 for non-Caucasians, 1.78 for chronic obstructive pulmonary disease, 1.26 for diabetes, and 1.09 for congestive heart failure. Propensity score matching yielded matches for 156 intervention patients (92%). The intervention showed a significantly lower 30-day readmission/death rate of 3.85% (6 of 156) compared with 11.54% (18 of 156) for the usual care matched group (p=0.023).

Input: Consider Input: Activation of NF-kappaB signaling pathway plays a critical role in the initiation and progression of carcinogenesis. However, the role of NF-kappaB pathway in esophageal squamous cell carcinoma (ESCC) has not been fully elucidated. Studies have shown that curcumin possesses anti-infection and anti-oxidation effects. This study was to evaluate whether curcumin could induce apoptosis through inhibition of NF-kappaB signaling pathway in ESCC cells.', 'Expressions of pIkappaBalpha and Bcl-2 were detected using Western blott after incubation of ESCC cells with curcumin (50 micromol/L) at different time points. Apoptosis and the number of viable ESCC cells were analyzed using flow cytometry and MTT, respectively, after the treatment of curcumin, 5-FU, or the combination of curcumin and 5-FU.', 'In two ESCC cell lines, EC9706 and Eca109,curcumin inhibited IkappaBalpha phosphorylation and Bcl-2 in a time-dependent manner; curcumin alone increased cell apoptosis (P<0.05), and the effect became more prominent when it was combined with 5-FU (P<0.05); curcumin plus 5-FU exerted a stronger inhibition effect on cell proliferation than curcumin alone (P<0.05) or 5-FU alone (P<0.05).
