    The comparison of exacerbation and pneumonia before and after conjugated pneumococcal vaccination in patients with chronic obstructive pulmonary disease, and the effect of inhaled corticosteroid use on results Introduction: Pneumococcal infections and exacerbations are important causes of mortality and morbidity in chronic obstructive pulmonary disease (COPD). The use of inhaled corticosteroids and pneumococcal vaccination are suggested for the control of the disease progression and exacerbations. The aim of this study is to assess the effect of pneumococcal conjugate vaccine on pneumonia and exacerbation in COPD patients using inhaled corticosteroids (ICSs). The secondary aim is to analyze the effect of ICS use and different ICS types, if administered, on exacerbation and pneumonia incidence in the study population. Materials and Methods: Medical records of 108 adult patients with COPD who were vaccinated with the pneumococcal conjugate vaccine (PCV13) were retrospectively evaluated. The number of acute exacerbations and pneumonia within one year before and after vaccination were evaluated in all included COPD patients. The comparison analysis was also performed based on the ICS types. Results: There were statistically significant differences between the mean numbers of pneumonia and exacerbations before and after vaccination (p< 0.05). There were no significant differences in the mean pneumonia attacks and acute exacerbations between patients using ICS and not using ICS (p> 0.05). Conclusion: This study revealed that PCV13 provides a significant decrease in both exacerbation and pneumonia episodes in COPD patients. On the other hand, the use of ICSs and the types of ICSs were not found to have adverse effects on pneumonia and acute exacerbations in vaccinated COPD patients.

    Determining factors affecting the acceptability of spirometry: A survey study in a tertiary chest diseases center Introduction: Unlike other laboratory tests, spirometry requires the participant's full compliance with the maneuvers in the test for an acceptable test result. In this study, we aimed to determine the suitability of spirometric tests regarding acceptability and the factors associated with acceptability. Materials and Methods: Before the test, our 15-scale questionnaire, prepared by us in the respiratory function laboratory, was applied to the participants who requested spirometric examination in our hospital. Afterwards, patients were subjected to spirometric analysis. Spirogram results of the participants were evaluated by four clinicians who were experts in the field based on the acceptability criteria in the American Thoracic Society and European Respiratory Society Spirometry Standardization Guidelines. Participants were divided into two groups as those who met the acceptability criteria and those who did not. Both groups were compared regarding demographic data, comorbidities, education levels, and questions in the questionnaire. Results: The acceptability spirometry rate was 71.2%. The most common error among those who could not perform an acceptable test was the inability to complete the expiratory time to the time that would create a plateau, with 37.3%. Education level and acceptability of spirometry were not related (p= 0.228). Asthma was statistically significantly higher in the group that per-formed acceptable spirometry (p= 0.049). Acceptable spirometry rate was statistically significantly higher in the participants who had previously per-formed spirometric tests compared to the other group (p< 0.001). The test success of the participants who did not have success anxiety about the test was significantly higher than the other group (p= 0.033). Conclusion: Reduction of participants' anxiety and repetitive testing increases test acceptability. For this reason, in our clinical practice, we recommend that people who want a spirometry test relieve their anxiety about the test and repeat the test in unacceptable tests.
