Purpose: In this study, we compared the roles of inflammatory parameters such as neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), C-reactive protein/lymphocyte ratio (CLR), monocyte/lymphocyte ratio (MLR), neutrophil/platelet ratio (NPR), neutrophil/monocyte ratio (NMR), CRP/albumin ratio (CAR), BUN/albumin ratio (BAR), MELD-XI score and 4C mortality score in predicting in-hospital mortality risk in COVID-19. Materials and Methods: A total of 117 patients over 18 years old with a PCR-confirmed diagnosis of COVID-19 between June 2020 and February 2021 were retrospectively included. The roles of parameters for independently predicting in-hospital mortality were determined and compared with each other using appropriate statistical methods. Results: Age, chronic kidney disease, diabetes mellitus, acute kidney injury, and length of hospital stay, urea, creatinine, LDH, AST, ferritin, D-dimer, CRP, albumin, Hb, CLR, BAR, CAR, MELD-XI score, and 4C mortality score were significantly correlated to in-hospital mortality. However, only the 4C mortality score and AST independently predicted in-hospital mortality in COVID-19 [OR 2.08 (%95 CI 1.06-2.36), for 4C mortality score, and OR 1.05 (%95 CI 1.00-1.10), for AST]. Conclusion: Unlike other mortality-related inflammatory parameters, the 4C mortality score and AST were independent and strong predictors of mortality in hospitalized COVID-19 patients.

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.

Objective: Prolonged T-peak to T-end (Tp-e), a ventricular repolarization parameter, has been related with ventricular arrhythmias (VAs). Novel electrocardiogram (ECG) parameters of ventricular repolarization have received considerable attention recently. In this study, we sought to investigate ventricular repolarization indexes such as the Tp-e and corrected Tp-e (Tp-ec) intervals, Tp-e/QT, Tp-e/QTc, and Tp-ec/QT ratios in patients with electrical injuries (EIs). Methods: Thirty-six patients diagnosed with EIs and 35 age- and sex-matched healthy control patients were included. Admission ECGs of the EI patients were compared with those of the healthy controls. QT and QTc intervals were measured, and the Tp-e and Tp-ec intervals, Tp-e/QT, Tp-ec/QT, and Tp-e/QTc ratios were then calculated from a 12-lead surface ECG. Results: The QT, Tp-e, Tp-e/QT, Tpe/QTc, Tp-ec/QT were not significantly different between the control group and the EI group (p > 0.05). However, the mean QTc interval was significantly higher in the EI group compared to the control group (412.81 +/- 25.46 vs 396.31 +/- 26.47 ms; p:0.009). Furthermore, the Tp-ec and Tp-ec/QT of the EI subgroup with elevated troponin levels significantly differed from those of the EI patients with normal troponin levels (p:0.033 and p:0.016, respectively). Conclusions: This retrospective study indicated that patients with EIs tend to have a prolonged QTc interval. Additionally, Tp-ec and Tp-ec/QT, which reportedly designate the tendency for VAs, were significantly higher in the EI patients with elevated troponin I levels than the EI patients with normal troponin levels, suggesting that patients with myocardial injury may be prone to VAs.

It is known that there is an increase in the frequency of psychiatric disturbances in the acute and post-illness phase of coronavirus disease (COVID-19). Comorbid psychiatric symptoms complicate the management of patients and negatively affect the prognosis, but there is no clear evidence of their progress. We aimed to determine psychiatric comorbidity in inpatients and outpatients with COVID-19 and recognize the factors that predict psychiatric comorbidity. For this purpose, we evaluated patients on the first admission and after 4 weeks. We investigated psychiatric symptoms in outpatients (n = 106) and inpatients (n = 128) diagnosed with COVID-19. In the first 7 days after diagnosis (first phase), sociodemographic and clinic data were collected, a symptom checklist was constructed, and the Hospital Anxiety and Depression Scale (HADS) and the Severity of Acute Stress Symptoms Scale (SASSS) were applied. After 30-35 days following the diagnosis, the SASSS and the HADS were repeated. In the first phase, the frequency of depression and anxiety were 55% and 20% in inpatients, and 39% and 18% in outpatients, respectively. In the second phase, depression scores are significantly decreased in both groups whereas anxiety scores were decreased only in inpatients. The frequencies of patients reporting sleep and attention problems, irritability, and suicide ideas decreased after 1 month. Patients with loss of smell and taste exhibit higher anxiety and depression scores in both stages. Our results revealed that the rate of psychiatric symptoms in COVID-19 patients improves within 1 month. Inpatients have a more significant decrease in both depression and anxiety frequency than do outpatients. The main factor affecting anxiety and depression was the treatment modality. Considering that all patients who were hospitalized were discharged at the end of the first month, this difference may be due to the elimination of the stress caused by hospitalization.

Objective: MELD-XI (Model for End-Stage Liver Disease Excluding INR) score predicts mortality in patients with heart failure. Herein, we assessed the role of MELD- XI score in predicting in-hospital mortality among heart failure patients having intracardiac cardioverter defibrillator (ICD) or cardiac resynchronization therapy with defibrillator backup (CRT-D) who presented with appropriate device shock or acute decompensated heart failure. Methods: We reviewed the medical records of patients with implantable cardioverter defibrillator or cardiac resynchronization therapy with defibrillator backup admitted to coronary care unit with acute decompensated heart failure or appropriate implantable device shocks between 01 January 2013 and 01 November 2018. MELD-XI score was compared between the deceased and surviving patients. The correlation of MELD-XI score with in-hospital mortality was sought. Results: There were 106 coronary care unit admissions of 67 patients (52 (77.6%) males and 15 (22.4%) females), who had a mean age of 64.8 (range 19-93) years. Eighty-eight (83.0%) admissions were for acute decompensated heart failure and 18 (17.0%) for appropriate device shock and/or electrical storm. A total of 16 (15.1%) patients died at hospital. The median MELD-XI score of the patients who died at hospital was significantly greater than that of the survivors (11.80 (0.59-28.98) vs 15.24 (9.11-24.64); p<0.05). A binary logistic regression analysis showed that MELD-XI score was a significant independent predictor of in-hospital mortality (X-2=1.229 (%95 CI 1.06-1.43); p<0.05). Conclusion: MELD-XI score successfully predicts in-hospital mortality among patients with ICD or CRT-D admitted with acute decompensated heart failure or appropriate implantable electronic device shocks.

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.
