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: Human cases of hypersensitivity pneumonitis (HP) have been reported among machinists for over 10 yr. Although mycobacteria have been implicated as causal agents, this has not been established in experimental studies and the mechanisms remain unclear. Other constituents of in-use metalworking fluids (MWFs) may also contribute to the development of lung disease. We investigated the potential for Mycobacterium immunogenum (MI) in MWFs to induce HP.', 'Mice were exposed intranasally for 3 wk to MI (isolated from MWFs), Saccharopolyspora rectivirgula (positive control), saline, endotoxin, MWFs spiked with endotoxin and/or MI, used MWFs, and particulate-fortified used MWFs. Responses were assessed 96 h after the last exposure.', 'Mice exposed to MI in MWFs developed lung pathology consistent with HP along with significantly more monocytes and neutrophils in lung lavage, increased CD4+/CD8+ T-lymphocyte ratio, and marked pulmonary lymphocytosis on histologic examination when compared with saline-treated control mice. Mice with Grade 2 or higher pathology (0-4 point scale) exhibited significantly elevated macrophage inflammatory protein-1alpha and IL-10 and a trend toward higher RANTES 96 h after the final dose. Endotoxin coexposure augmented lung pathology.

Input: Consider Input: To compare ambulatory blood pressure (ABP) in nonoverweight, prepubertal children with and without primary snoring (PS), and to investigate whether PS is a part of the dose-response relationship between sleep-disordered breathing (SDB) and BP in children.', 'This was a cross-sectional community-based study involving 190 children age 6 to 13 years. Each participant underwent an overnight sleep study and ABP monitoring after completing a validated sleep symptoms questionnaire. Individual systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial BP were calculated for wake and sleep periods. Subjects were hypertensive if mean SBP or DBP was > 95th percentile (relative to sex and height) of reference.', 'A total of 56 nonsnoring controls, 46 children with PS, 62 children with an apnea-hypopnea index (AHI) of 1 to 3, and 26 children with an AHI > 3 were identified. The daytime and nighttime BP increased across the severity spectrum of SDB. The dose-response trends for the proportion of subjects with nighttime systolic and diastolic hypertension also were significant. Nighttime DBP was significantly higher in the children with PS compared with controls after adjusting for age, sex, and body mass index.

Input: Consider Input: Coronary artery disease (CAD) is a major vascular complication of type 2 diabetes mellitus (T2DM) and reveals high mortality. Serum levels of chemerin have been suggested to be involved in glucose and lipid metabolism and associated with several cardiovascular factors. The aim of this study is to investigate the association of serum chemerin levels with the presence of CAD in patients with T2DM.', 'Serum levels of chemerin were determined in 286 patients with T2DM who underwent coronary angiography for the evaluation of CAD and 128 healthy subjects. The T2DM patients group included 150 patients with CAD and 136 patients without CAD.', 'Serum chemerin levels were significantly higher in T2DM patients with CAD compared with those without CAD and healthy controls. However, there was no significant difference in the levels of serum chemerin between T2DM patients without CAD and healthy controls. Multivariable logistic regression analysis revealed that serum chemerin levels were an independent determinant of the presence of CAD in patients with T2DM (OR 1.057, 95% CI 1.040 to 1.075; p < 0.001). In addition, linear regression analysis showed that serum chemerin levels were positively correlated with body mass index, systolic blood pressure, homeostasis model assessment of insulin resistance, and serum triglycerides.
