    Introduction: This study is aimed to evaluate the reliability and validity of the Turkish version of chronic obstructive pulmonary disease (COPD) Assessment Test (CAT) in seven centers. Materials and Methods: 321 patients between 4-75 years of age, diagnosed and staged by Global Initiative for Obstructive Lung Disease (GOLD) 2011 criteria were included. The Breathlessness, Cough, Sputum scale (BCSS), mMRC (Modified Medical Research Council) dyspnea index, St. George Respiratory Questionnaire (SGRQ), CAT and Short Form-36 (SF-36) were used concurrently. In the statistical analyses, internal consistency, item-total score correlation, explorative factor analysis, correlation with other scales were calculated. Results: The mean age was 62.4 ± 8.9 years and 89.7% of the patients were male (n= 288). Mean FEV 1% was 51.9 ± 19.2 and most of the patients were in Stage 3. CAT total score was 17.8 ± 9.5. In the internal consistency, Cronbach alpha coefficient was found as 0.9116 and item-total score correlation coefficients were between 0.62-0.79 and all were statistically significant (p< 0.0001). The correlation of the test-retest score calculated after two weeks with the initial score was 0.96 (p< 0.0001). In the structural validity, factor analysis with principle component analysis and varimax rotation was performed. One factor solution was achieved with eigenvalue of 4.956 and it represented 61.9% of the total variance. All the items were contained in the factor and the factor loads were between 0.71-0.85. The correlation coefficients of CAT with other indexes were moderate to good. The discrimination of CAT among disease stages has been shown to be significant (p< 0.0001) and a significant correlation was found with pulmonary function tests (p< 0.0001). Conclusion: It is demonstrated The Turkish version of COPD Assessment Tool is reliable and valid.

    Does high-frequency chest wall oscillation therapy have any impact on the infective exacerbations of chronic obstructive pulmonary disease? A randomized controlled single-blind study
    (2013) Goktalay T.; Akdemir S.E.; Alpaydin A.O.; Coskun A.S.; Celik P.; Yorgancioglu A.
    Objective: To investigate the impact of high-frequency chest wall oscillation in chronic obstructive pulmonary disease patients with infective exacerbation. Design: Clinical randomized controlled trial. Setting: Patients received high-frequency chest wall oscillation therapy at the Department of Pulmonology. Subjects: Stage III-IV chronic obstructive pulmonary disease patients hospitalized with acute infective exacerbation who had received high-frequency chest wall oscillation therapy were studied. Interventions: Patients were randomized into two groups, which were classified as I and II. All patients have been treated with bronchodilators, antibiotics, if necessary oxygen and patient education, as part of acute chronic obstructive pulmonary disease exacerbation protocol. Group II patients received additional high-frequency chest wall oscillation therapy. Main measures: Body mass index (B), forced expiratory volume in the first second (O), modified Medical Research Council dyspnea scale (D) and 6-minute walking test (E) (BODE) index, forced expiratory volume in the first second, dyspnea, exercise capacity, oxygenation parameters and hospitalization of duration were recorded at baseline and at three-days and five-days follow-up. Results: From April 2009 to July 2011, a total of 99 patients were assessed for eligibility, 50 patients were enrolled and randomized into two groups. A total of 50 (100%) patients (25 in Group I and 25 in Group II) were followed up for five days. Application of high-frequency chest wall oscillation therapy resulted in no significant advantage in all outcomes (p > 0.05). Mean (SD) baseline BODE index value in Group I was 7.72 (1.76), in Group II was 7.72(1.89) (p = 0.55). On the fifth-day assessment, mean (SD) BODE index value in Group I was 7.24 (1.83), in group II was 6.44 (2.46) (p = 0.18). © The Author(s) 2013.

    Validity and reliability of Turkish version of St. George's respiratory questionnaire; [St. George solunum anketinin Türkçe geçerlilik ve güvenilirliǧi]
    (2013) Polatli M.; Yorgancioǧlu A.; Aydemir Ö.; Yilmaz Demirci N.; Kirkil G.; Atiş Nayci S.; Köktürk N.; Uysal A.; Akdemir S.E.; Özgür E.S.; Günakan G.
    Introduction: The importance of the evaluation of health status in chronic obstructive pulmonary disease (COPD) is recently highlighted in many studies. In this study, we aimed to test the validity and reliability of the Turkish version of St. George Respiratory Questionnaire (SGRQ). Materials and Methods: The study was conducted in seven centers in Turkey. Three hundred and twenty one COPD patients (40-75 years) were included to the study. Turkish versions of breathlessness, Cough, and Sputum Scale (BCSS), mMRC (Modified Medical Research Council) dyspnea scale, SGRQ, COPD assessment test (CAT) and Short Form Health Survey (SF-36) were carried out to the patients. The statistical analysis of SGRQ was performed by using the coefficient of internal consistency, discriminative analysis for different stages and the correlation with the other scales. Results: The mean age was 62.4 ± 8.9 years and the mean FEV1 was 51.9 ± 19.2% pred. The coefficient of internal consistency (Cronbach alpha) was 0.8815. The correlation between the total score measured initially and that obtained two weeks later was found to be highly significant (r= 0.90, p< 0.0001). According the results of validation of both total score and the components of SGRQ, the correlation between the total score of SGRQ and CAT was 0.782 (p< 0.0001), SGRQ and SF- 36 was between -0.481 ile -0.819 (p< 0.0001). The total and component scores were able to discriminate different disease stages and a significant correlation was found to be with pulmonary function tests. Conclusion: SGRQ Turkish version is a reliable and valid assessment tool for COPD patients in clinical practice.

    A health survey in the workers of municipality; [Belediye çalışanlarında akciǧer saǧlıǧı taraması]
    (Ankara University, 2013) Göktalay T.; Şakar Coşkun A.; Havlucu Y.; Akdemir S.E.; Datli U.; Gümeli F.; Yorgancioǧlu A.
    Introduction: Internal and external air pollution that is gradually increasing due to urbanization and industrialization has a negative impact on the lung health. A health survey has been applied to evaluate the respiratory symptoms, respiration functions and smoking habits of the workers of Izmir Konak Municipality whom have been reported to have a high rate of smoking habit and be affected by the external air pollution due to their being working in the field by the Municipality's doctor. Materials and Methods: Questionnaire that are composed of the topics of work anamnesis, environmental anamnesis, curriculum vitae, symptoms (coughing, sputum, wheezing, dyspnea, hemoptysis) and smoking have been executed to 301 workers by face to face interview and their chest X-rays have been reviewed. Results: Dyspnea on exertion, sputum in the morning, wheezing and morning cough have been the most frequently observed complaints (respectively 37.2%, 32.2%, 27.9% and 24.9%). Sanitary workers have reported sputum in the morning more while maintenance shop workers have reported wheezing more (p values respectively 0.009, 0.008). No significance has been observed while the workers are evaluated one by one regarding to their work groups. No significant difference was identified between the addiction of smoking and nicotin addiction or pulmonary function test and chest X-rays (p> 0.05) but active smoking was much more seen in drivers (p= 0.047). Conclusion: Although working on the hazardous work branch does not institute a sharp distinction, it becomes significant to trace and lead the workers in order to obtain their lung health protection in long term. Informing and influencing the workers about the harms of smoking and the ways to quit has been the most considerable acquisition of this survey.
