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.

To determine whether a paper-based antibiotic ordering system is an effective antibiotic stewardship measure.', 'An antibiotic order form (AOF) was introduced in July 2001 at a pediatric tertiary care hospital. Vancomycin courses prescribed before and after the AOF introduction were retrospectively reviewed based on Hospital Infection Control Practices Advisory Committee guidelines. The impact of the AOF on the appropriateness of vancomycin prescribing was evaluated in univariate and multivariable analyses that adjusted for other factors associated with appropriateness of vancomycin use. The density of vancomycin use after introduction of the AOF was also assessed.', 'Compliance with the AOF was poor (<50%) during the planned study period; therefore an additional 2 months of improved compliance (70-80%) were included. Rates of inappropriate vancomycin use increased during the study periods: 35% before AOF; 39% post-AOF; and 51% during the improved compliance period. On adjusted analysis, vancomycin utilization was significantly more inappropriate after introduction of the AOF. Vancomycin doses per 1000 patient days increased after introduction of the AOF.

To probe into an new methods preserving parathyroid gland of patients with thyroid carcinoma.', 'Thirty-six patients with thyroid carcinoma that primary treated were random divided into two groups: trial group and control group. Emulsion of activated-carbon particles was injected into the thyroid gland of trial group patients. After thirty minutes, central compartment dissection was performed in the all patients. The black stained tissue in the dissection specimen of trial group was separated. Total lymph node, metastasis lymph node and parathyroid gland in the black stained tissue, and non-black stained tissue in the central compartment dissection specimen of trial group and central compartment dissection specimen of control group were counted respectively.', 'Nineteen and twenty central compartment dissection was performed in trial group and control group respectively. There are 177 lymph nodes included 83 metastasis lymph nodes in the black-stained tissue of central compartment dissection specimen of trial group. No parathyroid gland was found in the black-stained tissue. Nine lymph nodes included 2 metastasis lymph nodes and 7 parathyroid glands were found in the non-black stained tissue of central compartment dissection specimen of trial group. There were 124 lymph nodes included 80 metastasis lymph nodes and 8 parathyroid glands in central compartment dissection specimen of control group. There are statistic difference between the amount of lymph node in black stain tissue and that of control group (t = 0.340, P = 0.003). Rate of staining lymph node were 95.2 percent.

Nanoparticles may serve as a promising means to deliver novel therapeutics to the myocardium following myocardial infarction. We sought to determine whether lipid-based liposomal nanoparticles can be shown through different imaging modalities to specifically target injured myocardium following intravenous injection in an ischemia-reperfusion murine myocardial infarction model.', 'Mice underwent ischemia-reperfusion surgery and then either received tail-vein injection with gadolinium- and fluorescent-labeled liposomes or no injection (control). The hearts were harvested 24h later and underwent T1 and T2-weighted ex vivo imaging using a 7 Tesla Bruker magnet. The hearts were then sectioned for immunohistochemistry and optical fluorescent imaging.', 'The mean size of the liposomes was 100nm. T1-weighted signal intensity was significantly increased in the ischemic vs. the non-ischemic myocardium for mice that received liposomes compared with control. Optical imaging demonstrated significant fluorescence within the infarct area for the liposome group compared with control (16331% vs. 1314%, p=0.001) and fluorescent microscopy confirmed the presence of liposomes within the ischemic myocardium.
