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: Recent research suggests that preintervention functional magnetic resonance imaging (fMRI) data may predict weight loss outcomes among patients who participate in a behavioral weight loss plan. No study has examined whether presurgical brain activation can predict outcomes following bariatric surgery.', 'The aim of the present study was to determine if brain activations during a presurgical fMRI food-motivation paradigm are associated with weight loss 3 and 6 months following laparoscopic adjustable gastric banding (LAGB). Nineteen participants viewed food and nonfood pictures from a well-established food motivation paradigm during an fMRI scanning session before LAGB surgery. Weight was assessed presurgery and 3 and 6 months postsurgery; data for all participants was available at each time point. fMRI data were analyzed using the BrainVoyager QX statistical package. Whole brain voxelwise correlations of presurgery (food-nonfood) brain activation and weight, corrected for multiple comparisons, were performed to analyze the relationship between presurgical brain activation and subsequent weight loss. The settings were a medical university brain imaging center and 2 surgical weight loss centers in a major metropolitan area.', 'Increased activity in frontal regions associated with cognitive control (medial, middle, superior frontal gyrus) and posterior cingulate cortex was associated with weight loss following LAGB.

Input: Consider Input: Normal pressure hydrocephalus is a reversible neurologic disorder characterized by a triad of cognitive impairment, gait abnormality, and urinary incontinence that is commonly treated with ventriculoperitoneal shunt placement. However, multiple overlapping symptoms often make it difficult to differentiate normal pressure hydrocephalus from other types of dementia, and improved diagnostic techniques would help patient management. MR elastography is a novel diagnostic tool that could potentially identify patients with normal pressure hydrocephalus. The purpose of this study was to assess brain stiffness changes in patients with normal pressure hydrocephalus compared with age- and sex-matched cognitively healthy individuals.', 'MR elastography was performed on 10 patients with normal pressure hydrocephalus and 21 age- and sex-matched volunteers with no known neurologic disorders. Image acquisition was conducted on a 3T MR imaging scanner. Shear waves with 60-Hz vibration frequency were transmitted into the brain by a pillowlike passive driver. A novel postprocessing technique resistant to noise and edge artifacts was implemented to determine regional brain stiffness. The Wilcoxon rank sum test and linear regression were used for statistical analysis.', 'A significant increase in stiffness was observed in the cerebrum (P = .001), occipital lobe (P < .001), parietal lobe (P = .001), and the temporal lobe (P = .02) in the normal pressure hydrocephalus group compared with healthy controls. However, no significant difference was noted in other regions of the brain, including the frontal lobe (P = .07), deep gray and white matter (P = .43), or cerebellum (P = .20).

Input: Consider Input: Photodynamic therapy with aminolevulinic acid (ALA-PDT) is effective therapy for acne vulgaris; however, relatively strong side effects limit its wide usage. We have previously demonstrated that ALA-induced protoporphyrin IX distribution with lower concentrations and shorter contact time of ALA resulted in focused damage in sebaceous glands in vivo. We have formulated a protocol for ALA-PDT using 5% ALA with 2 hours contact time. The objective of this study was to establish the effectiveness and side effect profile of the new protocol in humans.', "Eleven Japanese patients (Fitzpatrick's skin type III - IV, mean age 23.7±7.2) with facial acne received topical application of 5% ALA for 2 hours with subsequent illumination by a broadband light (600 - 1100 nm, 15J/cm(2), 60 mW/cm(2)). Subjects were evaluated prior to the procedure, 1 month, and 3 months after the treatment by a blinded dermatologist using the global acne grading system (GAGS). Side effects were monitored through the treatment period.", 'The mean GAGS score decreased from 22.1±3.8 at baseline to 19.4 at 1 month, and to 16.3 at 3 months after PDT (P<0.05). Ten of eleven patients experienced local side effects, such as erythema, which were of minimal to mild severity. However, most side effects were of minimal to mild severity, and all of them resolved within several days without post inflammatory hyper pigmentation.
