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.

Example Input: We investigated suspected food intolerances in patients with irritable bowel syndrome (IBS) using confocal laser endomicroscopy (CLE) for real-time visualization of structural/functional changes in the intestinal mucosa after food challenge. Patients with functional changes after food challenge (CLE+) were placed on personalized exclusion diets and followed up for long-term symptom relief.', "Thirty-six IBS patients with suspected food intolerance and 10 patients with Barrett's esophagus (controls) without IBS symptoms were examined by CLE at University Hospital Schleswig-Holstein (Kiel, Germany). Diluted food antigens were administered directly to the duodenal mucosa through the working channel of the endoscope. Epithelial breaks, intervillous spaces, and the number of intraepithelial lymphocytes (IEL) were measured before and after the food challenge. CLE+ patients were placed on exclusion diets, given symptom score questionnaires, and followed up for 1 year; controls resumed their previous diet.", 'CLE showed a real-time response to food antigens in 22 of 36 patients; no responses were observed in 14 of 36 patients (CLE-) or any of the controls. Baseline IELs were significantly higher in CLE+ than CLE- subjects (P\xa0= .004); numbers increased significantly after food challenge (P\xa0= .0008). Within 5 minutes of exposure of CLE+ patients to food antigens, IELs increased, epithelial leaks/gaps formed, and intervillous spaces widened. Epithelial leaks and intervillous spaces also increased significantly in CLE+ vs baseline (both P < .001). The concordance of IELs measured by CLE and conventional histology was 70.6%; they did not correlate (P\xa0= .89; r(2)\xa0= 0.027). Symptom scores improved more than 50% in CLE+ patients after a 4-week exclusion diet and increased to 74% at 12 months; symptoms continued in CLE- patients.

Example Input: Immune dysregulation can affect insulin resistance (IR) and β-cell function and hence contribute to development of type 2 diabetes mellitus (T2DM). The complement system, as a regulator of immune and inflammatory homeostasis, may be a relevant contributor therein. However, longitudinal studies focusing on complement as a determinant of T2DM and IR are scarce. Therefore, we prospectively investigated the association of plasma complement factor 3 (C3) with (estimates of) IR in muscle, liver, and adipocytes, as well as with glucose tolerance, including incident T2DM.', 'Fasting C3, nonesterified fatty acids, glucose, and insulin (the latter two during oral glucose tolerance tests) were measured at baseline (n = 545) and after 7 years of follow-up (n = 394) in a prospective cohort study.', 'Over the 7-year period, C3 levels (per 0.1 g/L) were longitudinally associated with higher homeostasis model assessment of IR (HOMA2-IR; β = 15.2% [95% CI 12.9-17.6]), hepatic IR (β = 6.1% [95% CI 4.7-7.4]), adipocyte IR (β = 16.0% [95% CI 13.0-19.1]), fasting glucose (β = 1.8% [95% CI 1.2-2.4]), 2-h glucose (β = 5.2% [95% CI 3.7-6.7]), and area under the curve for glucose (β = 3.6% [95% CI 2.7-4.6]). In addition, greater changes in C3 (per 0.1 g/L) were associated with greater changes in HOMA2-IR (β = 0.08 [95% CI 0.02-0.15]) and greater changes in hepatic IR (β = 0.87 [95% CI 0.12-1.61]) over 7 years, but not glucose tolerance. Moreover, baseline C3 was associated with the 7-year incidence of T2DM (odds ratio 1.5 [95% CI 1.1-2.0]).

Example Input: The establishment of accurate equations for glomerular filtration rate (GFR) estimations is still far from the realization. Factors such as age, diabetes, stage of CKD, pregnancy, muscle mass and ethic nation are associated with less reliance upon commonly utilized estimation equations. We aimed to compare the routine use of 24-hour creatinine clearance (CrCl) and GFR estimates calculated by Crockoft-Gault (CG) and modification of diet in renal disease (MDRD) formulas in patients with different levels of renal dysfunction in subgroups, based on Body Mass Index (BMI) and serum albumin (Alb) levels.', 'Two hundred and seventy-nine non diabetic patients (172 men and 107 women), aged 54±23 years, with BMI 27.3±4.4 were enrolled in the study. All patients presented creatinine 1.8±1.2 (mg/dL) and Alb 3.5±1.3g/dL. The comparison of CrCl versus CG had bias 3.1 while the comparison of CrCl versus MDRD had a bias of 6.6.', 'Univariate analysis showed that age, sex and BMI were not significant biases related to the CG, MDRD and CrCl. Indeed, the bias related to the CG was significantly lower than that related to MDRD in patients with either low or high serum albumin. Interestingly, the bias associated with CG was 1.3 in non-diabetic patients with Alb ≤3.5 mg /dL suggesting that CG equation could be used interchangeable to CrCl in these patients.
