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]: Transfusion of packed erythrocytes stored for a long duration is associated with increased pulmonary arterial pressure and vascular resistance. Prolonged storage decreases erythrocyte deformability, and older erythrocytes are rapidly removed from the circulation after transfusion. The authors studied whether treating stored packed ovine erythrocytes with NO before transfusion could prevent pulmonary vasoconstriction, enhance erythrocyte deformability, and prolong erythrocyte survival after transfusion.', 'Ovine leukoreduced packed erythrocytes were treated before transfusion with either NO gas or a short-lived NO donor. Sheep were transfused with autologous packed erythrocytes, which were stored at 4°C for either 2 ("fresh blood") or 40 days ("stored blood"). Pulmonary and systemic hemodynamic parameters were monitored before, during, and after transfusion. Transfused erythrocytes were labeled with biotin to measure their circulating lifespan. Erythrocyte deformability was assessed before and after NO treatment using a microfluidic device.', 'NO treatment improved the deformability of stored erythrocytes and increased the number of stored erythrocytes circulating at 1 and 24\u2009h after transfusion. NO treatment prevented transfusion-associated pulmonary hypertension (mean pulmonary arterial pressure at 30\u2009min of 21\u2009±\u20091 vs. 15\u2009±\u20091 mmHg in control and NO-treated packed erythrocytes, P < 0.0001). Washing stored packed erythrocytes before transfusion did not prevent pulmonary hypertension.

[Q]: Pulmonary hypertension (PH) is prognosti- cally important in chronic obstructive pulmonary disease (COPD). Since PH only weakly correlates with hypoxemia, other factors must play a role.', 'To investigate whether polymorphisms of the serotonin transporter (5HTT), serotonin-2a receptor (5HTR2a) and endothelial nitric oxide synthetase (eNOS) are related to PH in COPD.', 'In 59 COPD patients who underwent right heart catheterization, 6-min walking distance, NYHA functional class, pulmonary function tests, blood gases and 5HTT, 5HTR2a and eNOS (4ab and T298C) polymorphisms were determined.', 'Forty-nine COPD patients in NYHA functional class III-IV were included. Ten were excluded due to comorbid causes of PH (mainly chronic thromboembolic). PH (mPAP > or =25 mm Hg) was present in 55% and usually mild, but out of proportion (mPAP > or =40 mm Hg) in 12%. Patients with PH had significantly higher frequencies of the 5HTT-L-allele (52%) compared to individuals without PH (36%), and LL homozygote patients had more severe PH. In patients with out-of-proportion PH, the L-allelic frequency was even 75%. We found no association of 5HTR2a and eNOS polymorphism with PH in COPD.

[Q]: All treatment in Crohn's disease, although palliative, aims at restoring full health. The objective of this study was to compare health-related quality of life and psychosocial conditions in patients with Crohn's proctocolitis with a general population.", "One hundred and twenty-seven patients with Crohn's proctocolitis (median age 44 years, 44.1% men) were compared with 266 controls (median age 45 years, 50.7% men). A questionnaire consisting of the Short Form-36 (SF-36), the Psychological General Well-Being Index (PGWB) and a visual analogue scale (VAS) evaluating general health as well as questions regarding psychosocial conditions was used. Disease activity was evaluated by Best's modification of the classical Crohn's Disease Activity Index.", 'Patients in remission had a health related quality of life similar to controls according to the SF-36 apart from general health where scores were lower (P < 0.01). Patients with active disease scored lower in all aspects of the SF-36 (P < 0.001 or P < 0.0001) as well as the PGWB (P < 0.0001). In a model for multiple regression including age, gender, concomitant small bowel disease, permanent stoma, previous colonic surgery, disease activity, duration, and aggressiveness, disease activity was the only variable negatively predicting all 8 domains of the SF-36 in the patient group (P < 0.001). The mean annual sick-leave for patients and controls were 33.9 and 9.5 days (P < 0.0001), respectively. Sixty-eight percent of the patients and 78.4% of the controls (P = 0.04) were married or cohabited, 67.7% and 78.0% (P = 0.04), respectively, had children.
