Methods: The study was designed as a cross-sectional study. A total of 154 participants (83 patients with asthma and 71 healthy volunteers) were enrolled into the study. Epicardial fat, carotid, and femoral intima media thicknesses were measured and recorded in both groups. The statistical difference between the two groups was examined. Results: Both carotid and femoral intima media thicknesses were significantly higher in patients with asthma compared to control group (5.52 +/- 0.4 mm vs. 5.36 +/- 0.4 mm; p = 0.038 and 5.64 +/- 0.4 mm vs. 5.46 +/- 0.5 mm; p = 0.036, respectively). However, there was not a significant difference in EFT between the groups [5.9 mm (5.3-6.6; IQR = 1.3) vs. 5.6 mm (4.7-6.5; IQR = 1.8); p = 0.1]. On comparison of control group and asthma subgroups (mild, moderate, and severe), there was a statistically significant difference among these four groups in terms of carotid and femoral intima media thicknesses (p = 0.002 and p < 0.001, respectively). Subgroup analyses showed that this difference was mainly due to patients with severe asthma. Conclusions: Carotid and femoral intima media thicknesses in asthmatic patients were found to be increased compared to the normal population. As a result, the risk of subclinical atherosclerosis in asthmatic patients may be high.Item Investigation of the Relationship Between Asthma and Subclinical Atherosclerosis by Carotid/Femoral Intima Media and Epicardial Fat Thickness Measurement(2017) Yilmaz, Mustafa; Yilmaz, Eylul Bozkurt; Sen, Nazan; Altin, Cihan; Muderrisoglu, Haldun; 0000-0002-2557-9579; 0000-0002-9635-6313; S-6973-2016; AAG-8233-2020Item The Approach to Community-Acquired Pneumonia: A Survey Study(2018) Ozyurek, Berna Akinci; Erturk, Arzu; Aydemir, Yusuf; Sen, Nazan; Alizoroglu, Dursun; Ozhan, Mustafa Hikmet; https://orcid.org/0000-0002-4171-7484; AAI-8947-2021INTRODUCTION AND AIM: Community-acquired pneumonia (CAP), which is often seen in daily practice, is a lower respiratory tract and pulmonary parenchyma infection which develops in society and daily life with community-acquired pathogens in individuals with no known immune failure. Delay in the treatment of pneumonia is known to increase morbidity and mortality. Various scoring systems are currently used in the identification of treatment groups in pneumonia. With the aim of evaluating the approach to CAP cases, the infection. MATERIALS AND METHODS: Working Group of the Turkish Respiratory Research Association (TUSAD) prepared a 22-item questionnaire. RESULTS: The survey was published on the TUSAD official website between July 2013 and June 2016. A total of 78 individuals responded to the questionnaire on the website. CONCLUSION: The responses to the questionnaire could indicate the way forward for new guidelines for physicians in respect of the approach to CAP.Item Liver Transplant and Reexpansion Pulmonary Edema: A Case Report(2018) Kara, Sibel; Sen, Nazan; Akcay, Sule; Moray, Gokhan; Kus, Murat; Haberal, Mehmet; 0000-0002-4171-7484; 0000-0002-8360-6459; 0000-0003-2498-7287; 0000-0001-6529-7579; 0000-0002-3462-7632; 29528016; AAI-8069-2021; AAI-8947-2021; AAB-5175-2021; AAE-1041-2021; AAJ-7870-2021; AAJ-8097-2021Hydrothorax occurs frequently in patients with end-stage liver disease and usually requires drainage of pulmonary effusion during the hepatectomy phase of liver transplant. Reexpansion pulmonary edema is a rare but potentially fatal complication seen after rapid reexpansion of the collapsed lung following thoracentesis of pleural fluid or tube drainage of pneumothorax. This condition, which manifests with various degrees of clinical severity, is rarely reported following liver transplantation. Herein, we present a 62-year-old male patient who developed reexpansion pulmonary edema after drainage of massive pleural effusion, which caused a total collapse in the right hemithorax during liver transplant. Six hours after pleural fluid drainage, the patient developed a nonproductive cough, mild tachypnea, shortness of breath, and low oxygen saturation (88%). His chest radiograph showed diffuse heterogeneous opacities in the right hemithorax. Computed tomography of the thorax revealed consolidations containing air bronchograms and ground glass opacities in the parenchyma of the right lung; these findings did not extend to the periphery and were observed less frequently in the inferoposterior left lung. These symptoms and radiologic findings were diagnosed as reexpansion pulmonary edema. Complete clinical and radiologic improvements were achieved within 72 hours of mechanical ventilatory support.Item Pneumonia in Renal Transplant Recipients: A Single-Center Study(2018) Kara, Sibel; Sen, Nazan; Kursun, Ebru; Yabanoglu, Hakan; Yildirim, Sedat; Akcay, Sule; Haberal, Mehmet; 0000-0002-4171-7484; 0000-0002-1161-3369; 0000-0002-5735-4315; 0000-0002-8360-6459; 0000-0002-3462-7632; 29528008; AAI-8947-2021; AAG-5020-2020; AAJ-7865-2021; AAF-4610-2019; AAI-8069-2021; AAB-5175-2021; AAJ-8097-2021Objectives: Pulmonary infections are a significant cause of morbidity and mortality in solid-organ transplant recipients despite enhanced facilities for perioperative care. The aim of this study was to evaluate the demographic characteristics, clinical course, and outcomes of renal transplant recipients with pneumonia. Materials and Methods: The medical records of all renal transplant recipients from January 2010 to December 2014 were retrospectively reviewed, and patients diagnosed with pneumonia according to Centers for Disease Control and Prevention criteria were evaluated. Pneumonia was classified as community acquired or nosocomial. Patient demographics, microbiologic findings, need for intensive care/mechanical ventilation over the course of treatment, and information about clinical follow-up and mortality were all recorded. Results: Eighteen (13.4%) of 134 renal transplant recipients had 25 pneumonia episodes within the study period. More than half (56%) of the pneumonia episodes developed within the first 6 months of transplant, whereas 44% developed after 6 months (all > 1 year). Eight cases (32%) were considered nosocomial pneumonia, and 17 (68%) were considered community-acquired pneumonia. Bacteria were the most common cause of pneumonia (28%), and fungi ranked second (8%). No viral or mycobacterial agents were detected. No patients required prolonged mechanical ventilation. No statistically significant difference was found in the need for intensive care or regarding mortality between patients with nosocomial and community-acquired pneumonia. Two patients (11%) died, and all remaining patients recovered. Conclusions: The present study confirmed that pneumonia after renal transplant is not a rare complication but a significant cause of morbidity. Long-term and close follow-up for pneumonia is necessary after renal transplant.Item Characteristics Of Our Hypoxemic COVID-19 Pneumonia Patients Receiving Corticosteroids And Mortality-Associated Factors(2022) Sengul, Aysun; Mutlu, Pinar; Ozdemir, Ozer; Satici, Celal; Turan, Muzaffer Onur; Arslan, Sertac; Ogang, Nalan; Unsal, Zuhal Ekici; Bozkus, Fulsen; Capraz, Aylin; Demirkol, Mustafa Asim; Mutlu, Levent Cern; Gulhanm, Pinar Yildiz; Alkilinc, Ersin; Fazlioglu, Nevin; Soyler, Yasemin; Kabalak, Pinar Akin; Kizilgoz, Derya; Turan, Pakize Ayse; Yildirim, Fatma; Aydemir, Yusuf; Sen, Nazan; Mirici, Arzu; 35839345Background COVID-19 is a disease associated with diffuse lung injury that has no proven effective treatment yet. It is thought that glucocorticoids may reduce inflammation-mediated lung injury, disease progression, and mortality. We aimed to evaluate our patient's characteristics and treatment outcomes who received corticosteroids for COVID-19 pneumonia. Methods We conducted a multicenter retrospective study and reviewed 517 patients admitted due to COVID-19 pneumonia who were hypoxemic and administered steroids regarding demographic, laboratory, and radiological characteristics, treatment response, and mortality-associated factors. Results Of our 517 patients with COVID-19 pneumonia who were hypoxemic and received corticosteroids, the mortality rate was 24.4% (n = 126). The evaluation of mortality-associated factors revealed that age, comorbidities, a CURB-65 score of >= 2, higher SOFA scores, presence of MAS, high doses of steroids, type of steroids, COVID-19 treatment, stay in the intensive care unit, high levels of d-dimer, CRP, ferritin, and troponin, and renal dysfunction were associated with mortality. Conclusion Due to high starting and average steroid doses are more associated with mortality, high-dose steroid administration should be avoided. We believe that knowing the factors associated with mortality in these cases is essential for close follow-up. The use of CURB-65 and SOFA scores can predict prognosis in COVID-19 pneumonia.Item Anxiety and Depression Levels of Healthcare Workers During COVID-19 Pandemic(2021) Turan, Muzaffer Onur; Demirci, Nilgun Yilmaz; Ak, Guntulu; Akcay, Sule; Akturk, Ulku Aka; Bilaceroglu, Semra; Coskun, Funda; Kokturk, Oguz; Mirici, Arzu; Cengiz, Ozdemi.

A differential cell count of BAL is conventionally performed by evaluating centrifuged samples under a light microscope and enumerating the stained cells. Another rarely used method to identify BAL leukocytes is flow cytometry (FCM). However, there are no guidelines for standardizing this method and related literature is limited. This study aimed to evaluate the accuracy of FCM for identifying BAL leukocytes. Methods: The BAL samples accepted to the hematology laboratory between 2014 - 2018 were retrospectively evaluated via light microscopy (LM) by a hematologist; while flow cytometric analyses with a monoclonal antibody panel composed of CD45/CD14/CD16 were noted by another doctor. The percentages of macrophages, lymphocytes, neutrophils and eosinophils determined by both methods were recorded for analysis. Correlations between the results from LM and FCM were investigated. In addition, compatibility between LM and FCM for denoting pathological values for each cell type was checked. Results: Among 140 reviewed BAL samples, 76 were included for further analysis. Comparisons revealed strong correlations between FCM and LM for identifying macrophages, lymphocytes, neutrophils, and eosinophils. In addition, regarding the normal cutoff values for each leukocyte type, FCM and LM were similar in the identification of pathological changes of all cell types except eosinophils. Conclusions: Flow cytometry was found to be feasible for use instead of LM and might become a more widely used technique to analyze BAL fluid in the future.
