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: We reviewed our experience with preoperative chemoradiotherapy in patients with adenocarcinoma of the distal esophagus and pretreatment endoscopic ultrasonography-identified celiac adenopathy.', 'One hundred eighty-six patients with adenocarcinoma of the distal esophagus were staged with endoscopic ultrasonography before treatment from 1997 through 2004. All patients were treated with concurrent chemoradiotherapy (CRT group) and surgical intervention or induction chemotherapy followed by concurrent chemoradiotherapy (C-->CRT group) and surgical intervention. Survival analysis (excluding operative mortality) evaluated various pretreatment factors.', 'Multivariable Cox regression analysis showed that pretreatment endoscopic ultrasonography-identified celiac adenopathy was a significant predictor of decreased long-term survival (P = .03). Median and 3-year survivals were 49 months and 54% in the endoscopic ultrasonography-identified cN0 M0 group (n = 65), 45 months and 56% in the endoscopic ultrasonography-identified cN1 M0 group (n = 96), and 19 months and 12% in the endoscopic ultrasonography-identified celiac adenopathy (cM1a) group (n = 18; P = .03). Increased systemic relapse was noted in the endoscopic ultrasonography-identified cM1a group (44% vs 22%, P = .07). The only factor associated with increased survival in the endoscopic ultrasonography-identified cM1a group (27 vs 15 months, P = .02) was the addition of induction chemotherapy before concurrent chemoradiotherapy and surgical intervention.

Input: Consider Input: Bacterial vaginosis is a risk factor for preterm birth. The various conventional methods for its diagnosis are laborious and not easily reproducible. Molecular quantification methods have been reported recently, but the specific risk factors they might identify remain unclear.', 'A prospective multicenter national study included pregnant women at risk of preterm birth. A quantitative molecular tool using a specific real-time polymerase chain reaction assay and serial dilutions of a plasmid suspension quantified Atopobium vaginae, Gardnerella vaginalis, lactobacilli, Mycoplasma hominis, and the human albumin gene (for quality control).', 'In 813 pregnancies, high vaginal loads of either or both of A. vaginae and G. vaginalis were associated with preterm birth (hazard ratio [HR], 3.9; 95% confidence interval {CI}, 1.1-14.1; P = .031). A high vaginal load of A. vaginae was significantly associated with shortened time to delivery and therefore pregnancy length. These times were, respectively, 152.2 and 188.2 days (HR, 5.6; 95% CI, 1.5-21.3; P < .001) before 22 weeks, 149.0 and 183.2 days (HR, 2.8; 95% CI, 1.1-8.2; P = .048) before 28 weeks, and 132.6 and 170.4 days (HR, 2.2; 95% CI, 1.1-4.6; P = .033) before 32 weeks. After multivariate analysis, A. vaginae levels ≥10(8) copies/mL remained significantly associated with delivery before 22 weeks of gestation (adjusted HR, 4.7; 95% CI, .2-17.6; P = .014).
