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.

[EX Q]: 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).

[EX Q]: Continuous support from follicular CD4(+) T helper (Tfh) cells drives germinal center (GC) responses, which last for several weeks to produce high affinity memory B cells and plasma cells. In autoimmune Sle1 and NZB/W F1 mice, elevated numbers of Tfh cells persist, promoting the expansion of self-reactive B cells. Expansion of circulating Tfh like cells have also been described in several autoimmune diseases. Although, the signals required for Tfh differentiation have now been well described, the mechanisms that sustain the maintenance of fully differentiated Tfh are less understood. Recent data demonstrate a role for GC B cells for Tfh maintenance after protein immunization.', 'Given the pathogenic role Tfh play in autoimmune disease, we explored whether B cells are required for maintenance of autoreactive Tfh. Our data suggest that the number of mature autoreactive Tfh cells is controlled by GC B cells. Depletion of B cells in Sle1 autoimmune mice leads to a dramatic reduction in Tfh cells. In NZB/W F1 autoimmune mice, similar to the SRBC immunization model, GC B cells support the maintenance of mature Tfh, which is dependent mainly on ICOS. The CD28-associated pathway is dispensable for Tfh maintenance in SRBC immunized mice, but is required in the spontaneous NZB/W F1 model.

[EX Q]: Recently, we developed a new method to measure collateral blood flow in rats: splenorenal shunt (SRS) blood flow (BF). The aims were to evaluate the reproducibility of SRSBF measurement in different models of portal hypertension, and to investigate the ability of SRSBF to disclose pharmacological changes.', 'Hemodynamics were determined in anesthetized rats with secondary biliary, CCl4 or DMNA cirrhosis and portal vein ligation (PVL) under baseline and pharmacological (octreotide, vapreotide) conditions. The main measurements performed were: SRSBF by the transit time ultrasound (TTU) method and % portosystemic shunts (PSS) by the microsphere method.', 'SRSBF was 6 to 10 times higher in portal hypertensive rats and was similar in the different models of cirrhosis but was higher in portal vein ligated rats than in cirrhotic rats (1.1+/-0.7 vs 0.6+/-0.7 ml x min(-1) x 100 g(-1), p=0.01). SRSBF was correlated with mesenteric %PSS (r=0.61, p<0.01), splenic %PSS (r=0.54, p<0.05), portal pressure (r= 0.32, p<0.05) and the area of liver fibrosis (r=0.33, p<0.05). Octreotide significantly decreased SRSBF (-23+/-20%, p<0.01 vs placebo: -6+/-8%, NS). Vapreotide significantly decreased SRSBF but not mesenteric or splenic %PSS compared to placebo. The variations in SRSBF (-26+/-32%) and in splenic %PSS (0+/-15%) with vapreotide were significantly different (p<0.05) and not correlated (r=-0.1, NS).
