    Objective: The aim of this study was to validate additive and logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE) models on Turkish adult cardiac surgical population. Methods: TurkoSCORE project involves a reliable web-based database to build up Turkish risk stratification models. Current patient population consisted of 9443 adult patients who underwent cardiac surgery between 2005 and 2010. However, the additive and logistic EuroSCORE models were applied to only 8018 patients whose EuroSCORE determinants were complete. Observed and predicted mortalities were compared for low-, medium-, and high-risk groups. Results: The mean patient age was 59.5 years (+/- 12.1 years) at the time of surgery, and 28.6\% were female. There were significant differences (all p < 0.001) in the prevalence of recent myocardial infarction (23.5\% vs 9.7\%), moderate left ventricular function (29.9\% vs 25.6\%), unstable angina (9.8\% vs 8.0\%), chronic pulmonary disease (13.4\% vs 3.9\%), active endocarditis (3.2\% vs 1.1\%), critical preoperative state (9.0\% vs 4.1\%), surgery on thoracic aorta (3.7\% vs 2.4\%), extracardiac arteriopathy (8.6\% vs 11.3\%), previous cardiac surgery (4.1\% vs 7.3\%), and other than isolated coronary artery bypass graft (CABG

    AIM: Despite technical and medical advances, aneurysmal subarachnoid hemorrhages (SAH) continue to be a challenging pathology, associated with high rates of morbidity and mortality. In this regard, a definition is required of the various prognostic indicators of an SAH. The aim of the present retrospective study is to examine the various prognostic factors of the clinical outcomes of the patients who underwent a neurosurgical clipping of aneurysms due to aneurysmal SAH. MATERIAL and METHODS: The data of 104 patients that had suffered an aneurysmal SAH were analyzed. The baseline demographic, clinical and radiological data were all analyzed. The prognostic study was derived from an analysis of these variables. Relationship between prognostic factors and outcome was evaluated by univariate and logistic multivariate regression analysis. RESULTS: This study has identified unfavorable outcomes on the Glasgow Outcome Scale at discharge after the surgical treatment of aneurysmal SAH associated with increased age, poor World Federation of Neurosurgical Societies (WFNS) grade on admission, higher Fisher's grade on admission computed tomography scan, larger aneurysm, and clinical vasospasm. In a multivariate logistic regression analysis, age, high WFNS grade, positive clinical vasospasm and size of aneurysm were found to be independent risk factors for mortality. The presence of hydrocephalus, number of aneurysms, positive risk factors, and the presence of Doppler vasospasm did not reach statistical significance. CONCLUSION: The most important prognostic factors in patients undergoing surgery due to aneurysmal subarachnoid hemorrhage were WFNS grade, age, size of aneurysm and clinical vasospasm.
