Background and aimsAnxiety and depression are common in patients with chronic obstructive pulmonary disease (COPD). The degree of lung function may not explain anxiety and depression. The aim of our study was to assess the psychological aspects of COPD, to test the BODE index (a composite score of body mass, obstruction, dyspnea and exercise capacity), and to evaluate the association between atypical cytologic findings of sputum, bronchoalveolar lavage (BAL) and the pyschological components of the disease.MethodsCOPD was classsified according to the GOLD stages based on forced expiratory volume in 1 second (FEV1) in 60 stable patients. The BODE index was calculated for grading COPD. The Hospital anxiety and depression (HAD) scale was used to appraise the anxiety and depression symptoms. Cytologic examination of sputum and BAL samples were performed in each patient. The cytologic findings were classified as normal, mild, moderate or severe atypia.ResultsThe overall prevalance of anxiety and depression symptoms was 41.7% and 46.7% respectively. The prevalance of these symptoms increased with increasing BODE stages and correlated well with the severity of atypical BAL cytology results (p < 0.001). Dyspnea and reduced exercise capacity were the predominant mechanisms leading to anxiety and depression symptoms associated with COPD.ConclusionsWe conclude that the BODE index is superior to GOLD stratification for explaining anxiety and depression symptoms in COPD. BAL cytologic findings, which reflect the distal parenchymal lung structure, correlated significantly with the presence of the anxiety and depression symptoms.

OBJECTIVES:Multiple genetic changes are observed in malignant tumors but are rare or absent in benign conditions. Aneuploidy is the most common feature of solid tumors including lung cancer and diagnosis of malignant tumors is possible through detection of aneuploidy. The aim of this study was to investigate chromosomal abnormalities in cells from non-small cell lung cancer patients obtained bronchoscopically and to evaluate the suitability of fluorescence in situ hybridization (FISH). MATERIAL AND METHODS:Bronchial lavage samples of 17 non-small cell lung cancer (NSCLC) patients were evaluated with fourcolor FISH using deoxyribonucleic acid (DNA) probes specific for the centromere regions of chromosomes 3, 7 and 8. tested specimens were first hybridized with probes, then visualized under fluorescence microscobeand captured with device's camera. RESULTS:High number of aneuploidic cells were detected in all the samples. Increased or decreased abnormal copies or chromosomes 3, 7 and 8 were obserced in all the 17 patients. Aneuploidy of chromosome 3 (21.35%) was higher than those of chromosome 7 (9.06%) and chromosome 8 (15.47%). Moreover, our results were significant for monosomy and trisomy of chromosome 3, trisomy of chromosome 7, nullisomy, monosomy and trisomy of, chromosome 8 (p< 0.05). CONCLUSION:It has been observed that FISH is a useful technique for detection of aneuploidy in bronchial lavage samples obtained by bronchoscopy. Interphase cells were evaluated without cell culturing with this method and high number of tumor cells were enumerated rapidly. Our study has demonstrated that, FISH technique may be used successfully in detection of chromosome number abnormalities in NSCLC patients and may facilitate evaluation of genetic abnormalities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
