Item Serum YKL-40/chitinase 3-Like Protein 1 Level Is an Independent Predictor of Atherosclerosis Development in Patients with Obstructive Sleep Apnea Syndrome(2015) Bakirci, Eftal Murat; Unver, Edhem; Degirmenci, Husnu; Kivanc, Tulay; Gunay, Murat; Hamur, Hikmet; Buyuklu, Mutlu; Ceyhun, Gokhan; Topal, Ergun; Coban, Taha Abdulkadir; 26142786Objective: The inflammatory process plays an important role in the development of cardiovascular complications in patients with obstructive sleep apnea syndrome (OSAS). YKL-40/chitinase 3-like protein 1 is a novel biomarker of systemic inflammation. This study aimed to investigate whether carotid intima-media thickness (CIMT), a useful marker for early atherosclerosis, is associated with serum YKL-40/chitinase 3-like protein 1 levels in patients with normotensive and nondiabetic OSAS. Methods: The study included 40 OSAS patients and 40 agesex- and body mass index-matched healthy controls. Serum YKL-40 levels were detected by enzyme-linked immunosorbent assay. CIMT was measured by B-mode ultrasound. Results: The patients with OSAS had significantly increased CIMT and higher YKL-40 and high sensitivity C-reactive protein (hsCRP) levels than those of the controls. CIMT was strongly correlated with serum YKL-40 levels (r=0.694, p<0.001), hsCRP (r=0.622, p<0.001), age (r=0.525, p=0.001), and weakly correlated with apnea-hypopnea index (AHI) (r=0.365, p=0.021) and the percentage of recording time spent (PRTS) of oxygen saturation <90% (r=0.488, p=0.001). Moreover, it was detected that serum YKL-40 levels were strongly correlated with AHI (r=0.617, p<0.001), and weakly correlated with SaO 2 <90% of PRTS (r=0.394, p=0.012) and hsCRP (r=0.486, p=0.001). In multiple regression analyses, age and serum levels of YKL-40 and hsCRP were found to be independent predictors of CIMT. Conclusion: In patients with OSAS, CIMT was increased. This increase was associated with serum YKL-40 level. Increased serum level of YKL-40 may be an early predictor of atherosclerosis development in patients with OSAS.Item Triple rule-out computed tomography angiography: Evaluation of acute chest pain in COVID-19 patients in the emergency department(2022) Bahadir, Suzan; Aydin, Sonay; Kantarci, Mecit; Unver, Edhem; Karavas, Erdal; Senbil, Duezguen Can; 0000-0002-0019-5851; 36160833; AAD-5931-2021BACKGROUND The aim of this study was to define clinical evidence supporting that triple rule-out computed tomography angiography (TRO CTA) is a comprehensive and feasible diagnostic tool in patients with novel coronavirus disease 2019 (COVID-19) who were admitted to the emergency department (ED) for acute chest pain. Optimizing diagnostic imaging strategies in COVID-19 related thromboembolic events, will help for rapid and noninvasive diagnoses and results will be effective for patients and healthcare systems in all aspects. AIM To define clinical evidence supporting that TRO CTA is a comprehensive and feasible diagnostic tool in COVID-19 patients who were admitted to the ED for acute chest pain, and to assess outcomes of optimizing diagnostic imaging strategies, particularly TRO CTA use, in COVID-19 related thromboembolic events. METHODS TRO CTA images were evaluated for the presence of coronary artery disease, pulmonary thromboembolism (PTE), or acute aortic syndromes. Statistical analyses were used for evaluation of significant association between the variables. A two tailed P-value < 0.05 was considered statistically significant. RESULTS Fifty-three patients were included into the study. In 31 patients (65.9%), there was not any pathology, while PTE was diagnosed in 11 patients. There was no significant relationship between the rates of pathology on CTA and history of hypertension. On the other hand, the diabetes mellitus rate was much higher in the acute coronary syndrome group, particularly in the PTE group (8/31 = 25.8% vs 6/16 = 37.5%, P = 0.001). The rate of dyslipidemia was significantly higher in the group with pathology on CTA while compared to those without pathology apart from imaging findings of the pneumonia group (62.5% vs 38.7%, P < 0.001). Smoking history rates were similar in the groups. Platelets, D-dimer, fibrinogen, C-reactive protein, and erythrocyte sedimentation rate values were higher in COVID-19 cases with additional pathologies. CONCLUSION TRO CTA is an effective imaging method in evaluation of all thoracic vascular systems at once and gives accurate results in COVID-19 patients.
