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: the use of antihypertensive medication in older people in order to prevent cardiovascular events is well established. The use of such agents has been encouraged by incentive schemes in the United Kingdom including the Quality and Outcomes Framework. In addition, many guidelines recommend good blood pressure (BP) control in the elderly. However, in older people antihypertensives can cause adverse effects related to hypotension.', 'the aim of this study was to assess the prevalence of low\xa0BP and impact on outcomes, particularly in the presence of antihypertensive treatment, in a primary care population of older people.', 'a retrospective observational cohort study in people over the age of 70 years registered with primary care providers in Kent.', 'a total of 11,167 patients over 70 years old were analysed, 6,373 female (57%). Systolic blood pressure (SBP) was below 120 mmHg in 1,297 people (844 on antihypertensives), below 110 mmHg in 474 (313 on antihypertensives) and below 100 mmHg in 128 (89 on antihypertensives). Hypotension was independently associated with mortality, acute kidney injury and hospital admission.

Input: Consider Input: Genetic variants in DLG5, which encodes a scaffolding protein on chromosome 10q23, and tumor necrosis factor (TNF)-alpha, encoding a proinflammatory cytokine on chromosome 6p, have recently been reported to be associated with inflammatory bowel disease (IBD). We studied these variants to seek evidence of association with IBD in a large independent dataset.', "We genotyped 1104 unrelated white IBD subjects-496 with Crohn's disease, 512 with ulcerative colitis, and 96 with indeterminate colitis from the Cambridge/Eastern (UK) panel-and 760 healthy control subjects for DLG5_113G/A, DLG5_4136C/A, TNF-857C/T, and TNF-1031T/C polymorphisms. Known Crohn's disease-predisposing variants in CARD15/NOD2 were also genotyped to permit analysis for reported epistatic interactions.", ": TNF-857 was shown to be associated with IBD overall (P = 0.0079). A formal interaction test showed that TNF-857 is associated equally with ulcerative colitis and Crohn's disease. Neither of the DLG5 alleles, however, was associated with IBD (P = 0.32 and 0.35). Subgroup analysis also failed to show evidence of association between either DLG5 allele or genotype frequencies and ulcerative colitis or Crohn's disease. Stratification of TNF-alpha and DLG5 cases by CARD15 genotype made no significant difference in the strength of associations.

Input: Consider Input: Current knowledge of the potential effects that several dietary lipids exert on immune functions indicates that these substances participate actively in the modulation of immune system by which they contribute to the improvement of the conditions of patients suffering from inflammatory disorders. However, long-chain n-3 polyunsaturated fatty acids induce an immunosuppressive status that leads to a reduction of the host natural resistance to infectious agents as well as to an enhancement of oxidative damage. Hence, the present study has been designed to evaluate the effects on the immune system of the antioxidant N-acetyl-L-cysteine (NAC) in mice fed dietary lipids and infected with Listeria monocytogenes.', 'Balb/c mice were fed for 4 weeks with diets containing either olive oil (OO, 20% by weight), fish oil (FO, 20% by weight) or hydrogenated coconut oil (HCO, 20% by weight). After dietary lipid administration mice were experimentally infected with L. monocytogenes or treated with NAC (25mg/ml intraperitoneally).', 'NAC at a concentration of 1mM promoted a loss of cell viability, although no differences were observed among the four groups. After injection of NAC in combination with L. monocytogenes, 25% of mice fed a low-fat (LF) diet survived. However, in the groups fed dietary lipids no effect on survival of mice was found. NAC participated in the reduction of superoxide anion generation measured with nitroblue tetrazolium (NBT) in the group fed a FO diet. Finally, NAC reduced the recovery of L. monocytogenes from spleen of mice fed diets containing LF or HCO.
