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: Parathyroidectomy (PTx) is the most successful treatment for advanced secondary hyperparathyroidism (2HPT) not responsive to medical treatment. However, persistent HPT remains problematic after PTx if some glands remain. The clinical course in patients with persistent 2HPT was evaluated to clarify the risk for re-operation after PTx.', 'Between March 1981 and December 2001, initial total PTx with forearm autograft were performed in 1156 uraemic patients. Persistent HPT cases were defined as those in which the lowest post-operative intact parathyroid hormone (i-PTH) concentration was >60 pg/ml, and patients were classified into groups A, B and C, with i-PTH concentrations of >or=500, 300-500 and 60-300 pg/ml, respectively. These patients were followed for 7-234 months after PTx.', 'Persistent HPT was identified in 49/1156 patients (4.2%), with nine cases in group A, 10 in group B and 30 in group C. Re-operation was required in 21/49 (42.8%) cases, and in seven of these the last i-PTH concentration was >or=500 pg/ml. All cases in group A required re-operation. In group C, 11/30 (36.7%) patients required re-operation. The missed glands removed at re-operation were supernumerary in 14 cases, and located in the mediastinum in 13 cases. The frequency of advanced HPT and re-operation was not negligible.

Input: Consider Input: Current basic or more advanced methods for analysis of averaged EEG/ERP are based on assumptions on the underlying processes, which are not necessarily precise.', 'In this work we present the findings of a method which obviates such assumptions and aims at a comprehensive analysis of the averaged EEG/ERP signal.', 'For the sake of demonstration we chose the established go/no-go paradigm in the context of ADHD. Our analysis method characterized two spatiotemporally distinct neurophysiologic processes which underlie the sampled signal: one which may be related to attention and the other which may be more related to perception.

Input: Consider Input: The purpose of this pilot study was to identify biological risk factors for restenosis after percutaneous transluminal coronary angioplasty (PTCA) to predict the long-term outcome of PTCA before treatment.', 'To investigate whether blood granulocytes and monocytes could determine luminal renarrowing after PTCA, several characteristics of these phagocytes were assessed before angioplasty in 32 patients who underwent PTCA of one coronary artery and who had repeat angiograms at 6-month follow-up. The plasma levels of interleukin (IL)-1 beta, tumor necrosis factor-alpha, IL-6, fibrinogen, C-reactive protein, and lipoprotein(a) before angioplasty were assessed as well. We found that the expression of the membrane antigens CD64, CD66, and CD67 by granulocytes was inversely associated with the luminal renarrowing normalized for vessel size (relative loss) at 6 months after PTCA, while the production of IL-1 beta by stimulated monocytes was positively associated with the relative loss. Next, these univariate predictors were corrected for the established clinical risk factors of dilation of the left anterior descending coronary artery and current smoking, which were statistically significant classic predictors in our patient group. Only the expression of CD67 did not predict late lumen loss independent of these established clinical risk factors. Multiple linear regression analysis showed that luminal renarrowing could be predicted reliably (R2 = .65; P < .0001) in this patient group on the basis of the vessel dilated and only two biological risk factors that reflect the activation status of blood phagocytes, ie, the expression of CD66 by granulocytes and the production of IL-1 beta by stimulated monocytes.
