Item Analysis of the relationship between tuberculosis-related mortality and nitrous oxide emission levels in the world with the environmental Kuznets curve method(2022) Torun, Serife; Yilmaz, Kadir; Ozkaya, Sevket; Yosunkaya, Sebnem; Akcay, Sule; 36326361Background/aim: It was aimed to analyze the relationship between tuberculosis-related mortality and nitrous oxide emission levels in the world with the Environmental Kuznets Curve (EKC) Method. Materials and methods: WHO ICD-10 mortality list data and the World Bank Country Data (WBCD) were used between 1997 and 2017 for 12 countries. Cubic regression analysis was used for EKC Analysis. Results: The difference between male and female deaths between 1996 and 1998 has increased sharply since 1999. Male deaths consistently occurred significantly more than female deaths. There was a significant and negative correlation between Nitrous oxide emissions (% change from 1990) and tuberculosis-related deaths, whereas there were significant and positive correlations between Nitrous oxide emissions in the energy sector (% of total) and tuberculosis-related deaths (p < 0.01). EKC analysis results showed that there is a U shaped between tuberculosis-related mortality and nitrous oxide emission levels in the world. Conclusion: Research results show that the relationship between nitrous oxide change and mortality is negative in the short term and positive in the long term. Therefore, although nitrous oxide gases cause respiratory diseases and mortality, it may be possible to transform a harmful environmental factor into a positive by developing devices or methods that will convert these gases into free radicals.Item Influenza viruses and SARS-CoV-2 in adult: 'Similarities and differences'(2021) Torun, Serife; Kesim, Cagri; Suner, Aynur; Botan Yildirim, Berna; Ozen, Ozgur; Akcay, Sule; 0000-0002-8964-291X; 0000-0001-7122-4130; 0000-0001-7730-1379; 34957739; AAD-5996-2021; AAN-1681-2021Introduction: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), causing a global pandemic starting from December 2019, showed a course that resulted in serious mortality in the world. In order to understand SARSCoV-2 better, here we aimed to compare the similar and different characteristics of Influenza viruses occurring in the same season with SARS-CoV-2. Materials and Methods: A total of 144 patients (31 patients with COVID-19, 62 patients with H1N1 influenza, and 51 patients with influenza B) were included in the study. Demographic findings, chronic diseases, laboratory values, chest x-ray, and chest CT findings of the patients were evaluated retrospectively. Results: Median age of the COVID-19 patients and rate of male patients were higher than other patient groups (55 years; p< 0.001) (61% male; p< 0.001). The most common chronic medical conditions were hypertension and diabetes. Platelet numbers and alanine aminotransferase values were significantly higher in COVID-19 patients. Radiologically, bilateral (74.2%) and nonspecific distribution (58.1%), ground-glass opacities with consolidation (51.6%), patchy image (25.8%), ground-glass opacities with interstitial changes (22.6%) and halo sign (22.6%) were quite evident than other groups in COVID-19 patients (p< 0.05). Conclusion: We suggest that due to the higher PLT values observed in COVID-19 patients, initiation of anticoagulant therapy should be considered in the early stage and routine follow-up with d-dimer and fibrinogen should be applied for suspected patients. Moreover, attention should be paid in terms of possible liver toxicity of the drugs to be used in treatment due the higher ALT values observed in COVID-19 patients. Since we did not detect SARS-CoV-2 and influenza viruses concurrently in the same patient, it may be helpful to focus on only one virus in a patient with symptoms, and radiographic differences can be used to differentiate COVID-19 from influenza.Item Radiological approaches to COVID-19 pneumonia(2020) Akcay, Sule; Ozlu, Tevfik; Yilmaz, Aydin; 0000-0002-8360-6459; 32299200; AAB-5175-2021COVID-19 pneumonia has high mortality rates. The symptoms are undiagnostic, the results of viral nucleic acid detection method (PCR) can delay, so that chest computerized tomography is often key diagnostic test in patients with possible COVID-19 pneumonia. In this review, we discussed the main radiological findings of this infection.Item Evaluation of Subclinical Atherosclerosis with Carotid Intima-Media and Epicardial Fat Thickness in Patients with Sarcoidosis(2020) Yilmaz, Hatice Eylul Bozkurt; Yilmaz, Mustafa; Erol, Tansel; Sen, Nazan; Unsal, Zuhal Ekici; Kara, Sibel; Habesoglu, Mehmet Ali; Akcay, Sule; 0000-0002-3628-4661; 0000-0002-2557-9579; 0000-0002-8360-6459; 0000-0003-3225-2686; 0000-0002-4171-7484; 32584234; AAN-5153-2021; S-6973-2016; AAI-8069-2021; AAB-5175-2021; AAD-5602-2021; AAI-8947-2021OBJECTIVES: Since many similar mechanisms may play a role in the pathophysiology of sarcoidosis and atherosclerosis, the risk of subclinical atherosclerosis may be increased in patients with sarcoidosis. The aim of this study was to evaluate known markers of subclinical atherosclerosis, namely epicardial fat thickness (EFT) and carotid intima-media thickness (CIMT) in patients with sarcoidosis. MATERIALS AND METHODS: This cross-sectional study included a total of 183 subjects, including 94 patients with sarcoidosis (patient group) and a control group of 89 healthy individuals. Measurements of EFT and CIMT were taken from all subjects and recorded. The groups were compared, and differences were analyzed statistically. RESULTS: EFT was higher in patients than in control subjects (6.42 +/- 1.12 mm vs 7.13 +/- 1.41 mm, p<0.001). CIMT was higher in patients than in control subjects (0.51 +/- 0.02 mm vs 0.52 +/- 0.02 mm, p=0.003). CONCLUSION: EFT and CIMT were found to be higher in patients with sarcoidosis than in healthy people. These results indicate that the risk of subclinical atherosclerosis might be increased in these patients.Item Diagnostic importance of maximum intensity projection technique in the identification of small pulmonary nodules with computed tomography(2020) Guleryuz Kizil, Pinar; Hekimoglu, Koray; Coskun, Mehmet; Akcay, Sule; 0000-0002-0805-0841; 0000-0001-5630-022X; 0000-0002-8360-6459; 32755123; AAD-9097-2021; AAM-4120-2021; AAB-5175-2021Item Diagnostic importance of maximum intensity projection technique in the identification of small pulmonary nodules with computed tomography(2020) Guleryuz Kizil, Pinar; Hekimoglu, Koray; Coskun, Mehmet; Akcay, Sule; 0000-0001-5630-022X; 0000-0002-0805-0841; 0000-0002-8360-6459; 32718138; AAM-4120-2021; AAD-9097-2021; AAB-5175-2021Introduction: In this retrospective study, the aim is to determine the sensitivity of maximum intensity projection (MIP) technique to 3 mm-thick axial sections in patients with small pulmonary nodules identified via examination using computed tomography (CT), and to identify whether this technique provides significant reduction in duration of nodule evaluation. Materials and Methods: A total of 69 patients (339 nodules) who underwent thoracic tomography due to various complaints and in whom pulmonary nodules were identified as a result of the examination were included in the study. Their axial sections that are 3 mm-thick and MIP sections obtained in the axial plane were evaluated by two different radiologists at different times by keeping time. the dimensions and evaluation times of the nodules were recorded separately for each method. Results: Evaluation compatibility between the radiologists was found to be 86.8% and it was considered to be perfectly compatible. Sensitivity of the 1st radiologist in the detection of nodules with MIP was 81.4%, whereas the sensitivity of the 2nd radiologist was 83.4%. In the evaluation for the reporting periods, when the duration of evaluation of MIP images were compared with the gold standard, a statistically significant reduction was found in the reporting times of both radiologists (p< 0.01). Conclusion: It was found that utilization of MIP images as an alternative method to detect pulmonary modules reduces the duration of evaluation significantly and provides the ability to detect nodules with high sensitivity. According to these data, MIP imaging may be preferred as an adjunct method in the evaluation of lung nodules as it provides fast and reliable information besides classical axial sections.
