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.

Peptone meal-stimulated gastric acid output is considered to be a reliable means to evaluate drug-mediated inhibition of stimulated gastric acid output, an important measure of the efficacy of the agents--such as proton pump inhibitors--used to treat acid-related disorders.', 'To compare the initial and overall inhibitory effects on peptone meal-stimulated gastric acid secretion of rabeprazole and omeprazole, 20 mg, in Helicobacter pylori-negative subjects on the first and eighth days of treatment.', 'Healthy volunteers (n = 27) were randomized in a single-centre, double-blind, double-dummy, 2 x 2 cross-over study. Subjects received an oral dose of rabeprazole or omeprazole, 20 mg once daily, for 8 days. After a 2-4-week washout period, subjects were crossed over to receive the other medication for 8 days. Peptone meal-stimulated gastric acid secretion was measured at hours 11 and 23 at baseline and on days 1 and 8 of treatment.', 'On days 1 and 8, rabeprazole demonstrated a significantly greater inhibition of peptone meal-stimulated gastric acid secretion compared with omeprazole at all time points (P < 0.03). Median values of steady-state inhibition on day 1 were statistically significant at hour 23 (rabeprazole 100% vs. omeprazole 74%, P < 0.02).

More than 90% of anal condyloma is attributed to nonhigh risk strains of human papillomavirus (HPV), thus patients with anal condyloma do not necessarily undergo HPV serotyping unless they are immunocompromised (IC). We hypothesized that IC patients with anal condyloma have a higher risk of high-risk HPV and dysplasia than nonimmunocompromised (NIC) patients.', 'We performed a retrospective chart review of patients who underwent surgical treatment by a single surgeon for anal condyloma from 1/2000 to 1/2012. HPV serotyping was performed on all patient samples. We compared incidence of high-risk HPV and dysplasia in condyloma specimens from IC and NIC patients.', 'High-risk HPV was identified in 14 specimens with serotypes 16, 18, 31, 33, 51, 52, and 67. Twenty-two cases (18.3%) had dysplasia. Invasive carcinoma was identified in one IC patient. The prevalence of dysplasia or high-risk HPV was not significantly different between IC and NIC groups. High-risk HPV was a significant independent predictor of dysplasia (odds ratio [OR] = 5.2; 95% CI = 1.24-21.62). Immune status, however, was not a significant predictor of high-risk HPV (OR = 1.11; 95% CI = 0.16-5.12) nor dysplasia (OR = 0.27; 95% CI = 0.037-1.17).

There is a great need for identification of biomarkers that could improve the prediction of early osteoarthritis (OA). We undertook this study to determine whether circulating levels of interleukin-6 (IL-6), tumor necrosis factor alpha (TNFalpha), and C-reactive protein (CRP) can serve as useful markers of radiographic knee OA (RKOA) in a normal human population.', 'RKOA data were obtained from the cohort of the Chingford Study, a prospective population-based study of healthy, middle-aged British women. The RKOA-affected status of the subjects was assessed using the Kellgren/Lawrence (K/L) grade as determined on radiographs obtained at baseline (n = 908) and at 10 years and 15 years thereafter. Serum levels of CRP, IL-6, and TNFalpha were assayed at 5, 8, and 15 years, using high-sensitivity commercial assays. A K/L grade of >or=2 in either knee was used as the outcome measure. Statistical analyses included analysis of variance for repeated measurements and logistic regression models, together with longitudinal modeling of dichotomous responses.', 'During 15 years of followup, the prevalence of RKOA (K/L grade >or=2) increased from 14.7% to 48.7% (P < 0.00001 versus baseline). The body mass index (BMI) and circulating levels of CRP and IL-6 were consistently and significantly higher in subjects diagnosed as having RKOA. When multiple logistic regression was applied to the data, the variables of older age (P = 3.93 x 10(-5)), higher BMI at baseline (P = 0.0003), and increased levels of IL-6 at year 5 (P = 0.0129) were determined to be independent predictors of the appearance of RKOA at year 10. The results were fully confirmed using longitudinal modeling of repeated measurements of the data obtained at 3 visits. The odds ratio for RKOA in subjects whose IL-6 levels were in the fourth quartile of increasing levels (versus the first quartile) was 2.74 (95% confidence interval 1.94-3.87).
