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.

This study was conducted to measure the corneal thickness changes associated with wearing 30-day tisilfocon A (Dk = 163) and 6-day etafilcon A (Dk = 28) contact lenses. The probable cause of the outcomes is discussed.', 'Thirty subjects were fitted with Menicon Z rigid gas-permeable (RGP) contact lenses and a control group (n = 30) was fitted with ACUVUE hydrogel lenses, at two study sites. After a 2-week period of daily wear, subjects began prolonged wear. Measurements were performed at the dispensing visit, and then at the 2-week daily wear, the 1-week, 6-month, and 12-month extended- and continuous-wear visits.', 'Repeated measures analysis of covariance was performed on mean corneal thickness. There was a significant increase in corneal thickness in the hydrogel lens extended-wear group compared to the RGP group (P = 0.03). The mean corneal thickness in the ACUVUE group was 2.58% higher at the 2-week daily wear visit, 2.38% higher at the 1-week extended-wear visit, 2.96% higher at the 6-month, and 2.97% higher at the 1-year visit compared to the RGP continuous-wear patients.

The lowest peak expiratory flow (PEF) over a week, expressed as a percentage of the highest PEF (Min%Max PEF) has been reported to be the index that most closely correlates with airway hyperresponsiveness (AHR) in asthmatics. However, both fluctuation of the airway caliber and airflow limitation are regarded as physiological properties of asthma closely related to AHR. An accurate index that shows the degree of AHR may be obtained by combining the index of airway lability with the parameters that represent airway caliber.', 'Ninety-two steroid-naive and twenty-eight steroid-treated asthmatic patients were enrolled. Using the physiological parameters obtained from spirometry and PEF monitoring, we investigated the indices which correlate accurately with airway responsiveness measured by the inhalation challenge test.', 'Although the methacholine threshold was related to all parameters that represent airway caliber and lability, Min%Max PEF had the strongest correlation with AHR. When Min%Max PEF was adjusted by the airway geometric factors, the normalization of Min%Max PEF with forced expiratory volume in one second as a percentage of the predicted value (%FEV(1)) improved the relationship between Min%Max PEF and AHR.

Mannose-binding lectin is an immune molecule that can bind to pathogens and initiate the complement cascade. In certain clinical situations, often characterized by immune compromise, mannose-binding lectin deficiency can increase the risk of infectious complications. Helicobacter pylori is one of the most common human infections and can bind mannose-binding lectin. Therefore, we examined whether mannose-binding lectin status influences the prevalence of H. pylori infection.', 'Two distinct populations were targeted. The first consisted of 166 volunteer blood donors, the second included 108 peripheral blood stem cell donors. All were tested for serological evidence of H. pylori infection, and had their mannose-binding lectin status characterized by genotyping, and quantification of mannose-binding lectin mannan-binding level and C4-deposition function in plasma.', 'H. pylori positive blood donors had higher blood mannose-binding lectin levels, as measured by C4 deposition (median 0.67 vs. 0.40, P=0.009, hazard ratio 2.82, 95% confidence interval 1.29-6.19) and mannan-binding assays (median 1.83 vs. 1.26, P=0.02, hazard ratio 1.28, 95% confidence interval 1.03-1.59). A trend was also found between the presence of an MBL2 coding mutation and a reduced prevalence of H. pylori. No significant associations were found in the second population.
