Item Carotid intima-media thickness in chronic obstructive pulmonary disease and survival: A multicenter prospective study(2019) Lakadamyali, Huseyin; Kivanc, Tulay; 30942958Introduction Chronic obstructive pulmonary disease (COPD) is associated with increased cardiovascular morbidity and mortality. Carotid intima-media thickness (CIMT) is a noninvasive method assessing atherosclerosis. Objective It was aimed to determine relationship and survival between COPD and CIMT. Methods CIMT was measured using Doppler ultrasound (USG) in 668 stable COPD patients at 24 centers. Patients were followed-up for 2 years. Results There were 610 patients who completed the study. There were 200 patients CIMT with <0.78 mm (group 1), and 410 with CIMT >= 0.78 mm (group 2). There was a significant difference at the parameters of age, gender, smoking load, biomass exposure, GOLD groups and degree of airway obstruction (FEV1) between groups 1 and 2. Our results revealed positive correlations between mean CIMT and age, smoking load (pack-years), biomass exposure (years), exacerbation rate (last year), duration of hypertension (years) and cholesterol level; negative correlations between CIMT and FEV1 (P < 0.05). According to logistic regression model, compared with group A, risk of CIMT increase was 2.2-fold in group B, 9.7-fold in group C and 4.4-fold in group D (P < 0.05). Risk of CIMT increase was also related with cholesterol level (P < 0.05). Compared with infrequent exacerbation, it was 2.8-fold in the patients with frequent exacerbation (P < 0.05). The mean survival time was slightly higher in group 1, but not significant (23.9 vs 21.8 months) (P > 0.05). Conclusion This study is the first regarding CIMT with combined GOLD assessment groups. It has revealed important findings supporting the increase in atherosclerosis risk in COPD patients. We recommend Doppler USG of the carotid artery in COPD patients at severe stages.Item Effects of right ventricular dysfunction on exercise capacity and quality of life and associations with serum NT-proBNP levels in COPD: an observational study(2014) Ozdemirel, Tugce Sahin; Ulasli, Sevinc Sarinc; Yetis, Begum; Karacaglar, Emir; Byraktar, Nilufer; Ulubay, GayeObjective: During the course of chronic obstructive pulmonary disease (COPD), pulmonary hypertension (PH) and right ventricular (RV) failure may develop due to elevated afterload of the RV. In those patients, exercise capacity is reduced due to pulmonary and cardiac limitations. We investigated relationships between serum N-terminal of proB-type natriuretic peptide (NT-proBNP) and RV functions with exercise capacity and quality of life in patients COPD. Methods: An observational case-control study was conducted. We enrolled 31 moderate and severe COPD patients, and 20 subjects without chronic diseases as control group. Parameters reflecting the right ventricular diastolic and systolic functions by echocardiography along with serum NT-proBNP levels were assessed. Cardiopulmonary exercise testing and Short Form-36 (SF-36) were applied. Results: Serum NT-proBNP levels were higher in COPD patients than control group (p=0.003). Serum NT-proBNP level was found to be related with pulmonary arterial pressure. Serum NT-proBNP levels were negatively correlated with anaerobic threshold oxygen uptake (AT VO2) and peak oxygen uptake (PVO2) values. Early ventricular filling velocity (Em) was lower in COPD patients. Em wave was significantly correlated with O-2 pulse. There was a positive relationship between tricuspid E/A ratio and VO2 value at AT. SF-36 domains of physical functioning, general health and role limitation due to physical disorder were significantly correlated with AT VO2, PVO2 and O-2 pulse. Conclusion: Exercise limitation may be predicted by assessment of right ventricule functions and NT-proBNP levels and exercise limitation impairs quality of life in COPD patients.Item Assessing the knowledge in primary health care following an educational course structured in the context of GARD chronic airway diseases national control program(2017) Balkan, Arzu; Oner Erkekol, Ferda; Kokturk, Nurdan; Mungan, Dilsad; Sackesen, Cansin; Onen, Zeynep Pinar; Ozkan, Secil; Ergun, Pinar; Kocabas, Can Naci; Baran Aksakal, Nur; Ekici, Banu; Ozkan Altunay, Zubeyde; Gemicioglu, Bilun; Yorgancioglu, Arzu; 0000-0002-4032-0944; 28990886; AAC-7548-2020Introduction: Chronic obstructive pulmonary diseases are common causes of disease in the community and account for considerable percent of the caseload in primary health care facilities. For this reason, it is important to question and improve the knowledge of primary health care physicians. This study is designed to assess the level of knowledge for bronchial asthma and COPD of the primary healthcare physicians, both before and immediately after an educational course structured in the context of GARD Chronic Airway Diseases National Control Program. Materials and Methods: The participating physicians attended an intensive educational course on asthma and COPD. Twenty five item questionnaires for asthma and COPD were administered to the participants both before and immediately after the end of the course. Contribution of education to the level of knowledge was investigated by comparing the percentages of the correct answers in the pre-and post-test. Results: From 11 different cities, 1817 and 1788 primary health care physician were attended to the asthma and COPD educations, respectively. The accuracy rate of >= 75% was obtained from only 4 questions in pre-test asthma questionnaire. On the contrary, in 15 questions the accuracy rate was < 50%. The mean accuracy rate for the whole asthma test was 45.8%, and this rate raised to 69.6% after education course. The accuracy rate of >= 75% could not be obtained from any of the questions in pre-test COPD questionnaire. On the contrary, in 19 questions the accuracy rate was < 50%. The mean accuracy rate for the whole asthma test was 42.0%, and this rate raised to 71.3% after education course. Conclusion: It has been shown that, in primary care settings, the level of knowledge in asthma and COPD should be enhanced and that this increase can be achieved with an education course.Item Humidification therapy; long-term effects in COPD and OSAS patients(2018) Esendagli, Dorina; Sarric Ulasli, Sevinc; Esquinas, Antonio; 0000-0002-6619-2952; 30020043; ABF-9398-2020Humidification therapy is widely used in patients during invasive ventilation and the importance of heating and humidifying the inhaled air is well defined in both the acute and long term setting. On the other hand the continuous usage of humidification in noninvasive ventilation is controversial and the long term effects are still not well defined. The usage of noninvasive ventilation is especially important in hypercapnic Chronic obstructive pulmonary disease (COPD) and also the obstructive sleep apnea syndrome (OSAS) patients and compliance to this treatment is essential in long term. Limited number of studies have shown that heated humidification is preferred by COPD patients and might help in mucus clearance, reduce mucus viscosity and help in expectoration, but there was shown no priority as far as concerns the lung function or blood gas parameters. Humidification might also be important in long term oxygen treatment since the inhalation of dry air can lead to ciliary dysfunction, alterations in mucus properties and mucociliary clearance impairment. Studies concerning OSAS patients showed that humidification helps to reduce the nasal symptoms but plays no role in increasing the compliance of patients in long term. Multi-center studies with large number of patients are needed to identify patients' groups who are likely to benefit from the addition of humidification to noninvasive therapy.
