    Objective: Systemic inflammatory parameters are predictors of poor prognosis in COVID-19 patients. This study evaluated whether the prognostic nutritional index, which was also related to nutrition risk and other inflammation-based prognostic scores, was predictive of in-hospital mortality in COVID-19 patients.Materials and Methods: This was a retrospective cross-sectional single-center study. Based on the exclusion criteria, 151 patients over 18 years old diagnosed with COVID-19 and hospitalized in the intensive care unit between March 2020 and December 2020 were eligible for this study. Multivariable logistic regression analysis was performed to evaluate the predictive value of the Glasgow Prognostic Score (GPS), Prognostic Index (PI), Prognostic Nutritional Index (PNI), and Systemic Inflammatory Index (SII).Results: In the univariate analyses, age, diabetes mellitus (DM), chronic kidney disease, acute kidney injury, hypothyroidism, hospitalization stay, lactate dehydrogenase (LDH), as-partate aminotransferase (AST), D-dimer, ferritin, C-reactive protein (CRP), albumin, hemoglobin level, platelet count, urea, creatinine level, PNI, GPS were significantly associated with mortality. However, in the multivariable logistic regression analysis of the inflamma-tion-based prognostic scores, only PNI was statistically significant in predicting in-hospital mortality (OR=0.83; [95% CI=0.71-0.97]; p=0.019).Conclusion: PNI is a more useful and powerful tool among these inflammation-based prognostic risk scores in predicting in-hospital mortality in COVID-19 patients.

    An epidemiological study to define the recent clinical characteristics and outcomes of infective endocarditis in southern Turkey
    (2021) Acibuca, Aynur; Yilmaz, Mustafa; Okar, Sefa; Kursun, Ebru; Acilar, Onur; Tekin, Abdullah; Demiroglu, Yusuf Ziya; Muderrisoglu, Ibrahim Haldun; 0000-0002-9866-2197; 0000-0002-5658-870X; 33830167; AAZ-9711-2021; ABD-7304-2021
    Introduction: The aim of this study was to characterise the recent features of patients with infective endocarditis (IE) at one referral centre in southern Turkey, in order to be able to identify the high-risk subgroup and revise preventative measures and management strategies. Methods: Medical records of patients 18 years and older, who had been diagnosed with IE according to the Duke criteria between January 2009 and October 2019, were retrospectively evaluated in a referral general hospital. Results: The total of 139 IE cases comprised 59.7% males and 40.3% females, with a mean age of 55 +/- 16 years. The most encountered symptom was fever (55.4%) and the mitral valve (54%) was the most frequently involved. The most common causative micro-organisms were coagulase-negative staphylococci (30.2%). The in-hospital mortality rate was 30.2%, with congestive heart failure, chronic renal disease and chronic dialysis found to be significantly associated with in-hospital mortality. Conclusion: The study results demonstrate the recent epidemiological features of IE in southern Turkey that are important for clinicians to manage diagnostic and therapeutic processes successfully. Older age, the predominance of staphylococci and higher surgery rates are consistent with the changing trends of IE in some parts the world.

    MELD-XI score predicts in-hospital mortality independent of simplified pulmonary embolism severity index among patients with intermediate-to-high risk acute pulmonary thromboembolism
    (2019) Ciftci, Orcun; Celik, Casit Olgun; Uzar, Guldeniz; Kupeli, Elif; Muderrisoglu, Ibrahim Haldun; 31709948
    Introduction: Acute pulmonary thromboembolism (PTE) is a highly morbid and fatal condition. Although several risk stratification models exist for prediction of mortality risk in PTE, no study has yet focused on the effect of impaired vital organ function, such as renal or hepatic impairment, on mortality in PTE. MELD-XI (Model for end-stage liver disease excluding INR) score predicts mortality among patients with end-stage hepatic and cardiovascular disorders. Herein, we aimed to test MELD-XI score for predicting in-hospital prognosis of patients with intermediate-to-high risk acute PTE. Materials and Methods: We reviewed the medical records patients older than 18 years hospitalized with intermediate-to-high risk PTE between 01.06.2011 and 01.01.2019. Simplified pulmonary embolism severity index (sPESI) score and MELD-XI score were calculated, and in-hospital mortality determined. MELD-XI score was compared between patients with and without in-hospital mortality and was correlated to sPESI score. The predictive power of MELD-XI score for in-hospital mortality was sought and an in-hospital survival analysis with Kaplan Meier curve and log-rank test was done for MELD-XI score. Results: A total of 104 patients [mean age of 70.8 +/- 15.9 years; 68 (65.4%) females]. Fourteen (13.5%) patients died at hospital. MELD-XI and sPESI scores were significantly correlated to each other and were higher in deceased patients than the survivors [17.3 (IQR 14.3) vs. 10.12 (IQR 2.99); p < 0.05 and 2 (IQR 1) vs. 1 (IQR 1); p < 0.05, respectively]. MELD-XI score and sPESI score were significant predictor of in-hospital mortality in multivariate analysis. A MELD-XI score >= 10.25 had a sensitivity of 78.6% and a specificity of 70.0% for in-hospital mortality. A survival analysis revealed that a high MELD-XI category (MELD-XI score >= 10.2) significantly worsened in-hospital survival (p < 0.01; log rank test). Conclusion: MELD-XI score performs well for mortality prediction among patients with intermediate-to-high risk PTE. This subject needs to be further studied by large, randomized controlled studies.
