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.

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.

To determine the frequency and clinical significance of epidermal growth factor receptor (EGFR) mutations in patients with potentially curable stage III non-small-cell lung cancer (NSCLC) who are eligible for definitive chemoradiotherapy (CRT).', 'Between January 2001 and December 2010, we analyzed the EGFR mutational status in consecutive NSCLC patients who were treated by CRT. The response rate, relapse-free survival, 2-year relapse-free rate, initial relapse sites, and overall survival of the patients were investigated.', 'A total of 528 patients received CRT at our hospital during the study period. Of these, 274 were diagnosed as having nonsquamous NSCLC. Sufficient specimens for mutational analyses could be obtained from 198 of these patients. The proportion of patients with EGFR activating mutations was 17%. In addition to the well-known characteristics of patients carrying EGFR mutations (female, adenocarcinoma, and never/light smoker), the proportion of cases with smaller primary lesions (T1/2) was found to be higher in patients with EGFR mutations than in those with wild-type EGFR. Patients with EGFR mutations showed similar response rate, relapse-free survival, and 2-year relapse-free rates as compared to patients with wild-type EGFR. Local relapses as the site of initial relapse occurred significantly less frequently in patients with EGFR mutation (4% vs 21%; P=.045). Patients with EGFR mutations showed longer local control (adjusted hazard ratio 0.49; P=.043). After disease progression, a majority of the patients with EGFR mutations received EGFR tyrosine kinase inhibitors (62%), and these patients showed longer postprogression survival than those with wild-type EGFR.

In emergency cases, finger stick testing is primarily used to check the blood glucose value of patients since it takes longer to obtain the venous value. In critical patients, under conditions that cause an increase in metabolic state and level of stress, there occurs considerable difference in glucose levels between capillary and venous measurements. This study aimed to investigate the comparability of capillary and venous glucose values, according to the perfusion index level obtained with the Masimo Radical-7(®️) device, in critical patients aged 18 years and over.', 'We conducted this prospective and observational study in the emergency department of the Eskisehir Osmangazi University hospital between November 3, 2008 and February 2, 2009.', 'The blood glucose of 300 critical patients was checked by finger stick in the emergency unit. The participants with normal vital signs had perfusion index between 0 and 5; the results obtained by the two methods were more consistent for perfusion index values of 6 and over. The results were most consistent in aged participants with normal vital sign findings and low perfusion index and in young patients with high perfusion index. In the cases where at least one of the vital signs was abnormal, the glucose values obtained by the two methods were more consistent when the perfusion index was 6 or over. In this group, independently from the perfusion index value, the consistency was higher in younger patients compared with aged patients.
