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: Studies on the safety of aprotinin in coronary artery surgery have given conflicting results. Therefore, we studied the possible link between perioperative aprotinin treatment and renal dysfunction in patients undergoing first-time coronary surgery with a high risk of bleeding.', 'We performed a matched cohort study, comparing 200 patients receiving high-dose aprotinin with 200 patients receiving tranexamic acid during primary isolated coronary surgery. Patients were matched according to age, sex, and presence of acute coronary syndrome. Primary outcome was fractional change in creatinine clearance. Secondary outcomes were other evaluations of postoperative renal function, mortality, stroke, reoperation for bleeding, and transfusion requirements.', 'The groups were similar in baseline characteristics except that triple-vessel disease and history of myocardial infarction were more prevalent in the aprotinin group. No significant differences were found in fractional change in creatinine clearance (-11% versus -12%, medians, p = 0.75) or any other assessments of postoperative renal function between the tranexamic acid and the aprotinin group. Adverse event rates were similar: early mortality (3.5% versus 4.5%, p = 0.80), stroke (1.5% versus 2%, p = 1.0), reoperation for bleeding (3.5% versus 2.5%, p = 0.77), and 5-year survival (87% versus 84%, p = 0.17). Patients in the aprotinin group received fewer transfusions (48% versus 60.5%, p = 0.02), fewer units of packed red blood cells (2.0 versus 1.4, p = 0.02) and plasma (1.3 versus 0.5, p < 0.001), but more units of platelets (0.1 versus 0.2, p = 0.02).

Q: Genetic factors are reported to affect fracture incidence. Many groups have explored the correlation of fracture risk with ESR1 IVS1-397T>C. The observed associations, however, are largely inconsistent. This meta-analysis of data from early-released studies was performed in an effort to determine the role of IVS1-397T>C in fracture.', 'Relevant studies were searched through Pubmed, Embase, ScienceDirect, and Wiley Online Library databases. 16 studies meeting all selection criteria were finally identified. We calculated ORs with 95% CIs to assess risk of fracture. Subgroup analyses were performed by subtype, ethnicity and gender.', 'Data on 2916 cases and 19170 controls were analyzed in the meta-analysis. Overall, we found moderately decreased risk in association with IVS1-397 CC genotype (OR = 0.82, 95% CI = 0.73-0.92; OR = 0.84, 95% CI = 0.76-0.94). The decrease persisted in both hip fracture (OR = 0.82, 95% CI = 0.71-0.94; OR = 0.83, 95% CI = 0.73-0.94) and vertebral fracture (OR = 0.67, 95% CI = 0.50-0.91; OR = 0.78, 95% CI = 0.64-0.97; OR = 0.82, 95% CI = 0.68-0.98) when data were stratified by subtype. We also found a significant trend of decreasing risk in relation to the CC genotype in Caucasian, male and female. All fixed-effects meta-analysis results were homogeneous.

Q: The APOE genotype has a uniquely strong influence on the outcome of viral infection. The mechanism is unknown, although one possibility is direct inhibition of viral entry into cells.', 'We have examined the direct anti-infective activity of a peptide analogue of the receptor-binding region of apolipoprotein E (apoE) that is known as "apoE dimer tandem repeat peptide" (apoEdp) and has previously been shown to mimic some of the biological effects of apoE and that recently was shown to bind low-density lipoprotein receptor-related protein.', 'apoEdp has activity against herpes simplex virus types 1 and 2, human immunodeficiency virus, Pseudomonas aeruginosa, and Staphylococcus aureus; concentrations in the range of 1-20 micromol/L inhibit infection by 50%. These biological actions depend on adoption of an alpha -helical structure, as has been found for other biological effects of apoE peptides. The peptide interferes with the earliest stages of viral infection, preventing viral attachment and exerting a mild virucidal action. In addition, an N-terminal fragment of apoE that also contains this binding domain has antiviral activity.
