Abstract Introduction CHA2DS2-VASc score is used to determine the thromboembolic risk, but its prognostic value has been demonstrated in several cardiovascular (CV) diseases. Except for female gender, many CV risk factors comprising this score are recognized as risk factors for mortality in COVID-19. Cetinak G. et al demonstrated the ability of modified CHA2DS2-VASc (M-CHA2DS2-VASc) to predict mortality in COVID-19, which is based on changing gender criteria from female to male. Purpose To evaluate the prognostic value of a M-CHA2DS2-VASc score to predict pulmonary embolism (PE) and mortality in pts with COVID-19 admitted at the emergency department (ED). Methods Retrospective study of pts admitted to the ED between June 2020-January 2021, who underwent computed tomography pulmonary angiography (CTPA) due to PE suspicion. Pts were stratified into 3 M-CHA2DS2-VASc risk groups: lower (0–1), intermediate (2–3) and high risk (≥4). Kruskal-Wallis and X-square test were used to compare score risk groups. Logistic regression was used to determine predictors of PE and mortality. ROC curve was performed to evaluate the discriminative power of the score. Results We included 300 pts: median age 71 years, 59% male. Hypertension (59%) chronic kidney disease (CKD, 33%), dyslipidemia (32%) and diabetes (28%) were the most common comorbidities. PE was diagnosed in 46 pts (15%). We found no difference in PE incidence according to M-CHA2DS2-VASc groups (p=0.531) and it showed no predictive value for PE (OR: 1.050, p=0.596). The AUC of M-CHA2DS2-VASc was 0.52, suggesting no discriminative power to predict PE. Regarding mortality, M-CHA2DS2-VASc score was higher in non-survivors COVID-19 pts than in survivors [4 (IQR 3–5) vs 2 (1–4), respectively, p<0.001]. A multivariate logistic regression analysis was performed for mortality based on M-CHA2DS2-VASC, troponin, CKD and smoking history, and only M-CHA2DS2-VASc was identified as an independent predictor of mortality (OR: 1.406, p=0.007). Kaplan-Meier showed that M-CHA2DS2-VASc score was associated with mortality: the survival rate was 92%, 80% and 63% in the lower, intermediate and higher M-CHA2DS2VASc score risk group (logrank test p<0.001; Fig. A). Most of the pts in the cohort were hospitalized (83%), but 21 pts (17%) discharged from the ED. Among these pts, 33% (n=17) had low risk, 37% (n=19) intermediate risk and 29% (n=15) high risk for mortality according to the M-CHA2DS2VASc score. The Kaplan-Meier individual survival analysis for hospitalized patients (Fig. B) and for those discharged from the ED (Fig. C) showed that M-CHA2DS2-VASc score had a good discriminative ability to predict short-term mortality for both groups (logrank test p<0.001 and p=0.007, respectively). Conclusion Considering the lack of validated scores to predict mortality in COVID-19 pts, the M-CHA2DS2-VASc might be a simple tool to predict short-term mortality in these pts, irrespectively of the need for hospitalization or not.

Abstract Background and Objective: One of the causes of short-term mortality in patients is the lower quality of services provided by hospital emergency departments. Given the particular importance of the hospital emergency system and the presence of numerous problems, as well as short term mortality rates in hospitals, this study aimed to investigate the risk factors affecting short term mortality of patients presenting to the Emergency Department at Nemazi Hospital in Shiraz, Fars province in 2019.Methods: This is a retrospective study with a case control-analytical design. The sample size was 768 subjects. In the present study, the emergency department overcrowding was measured by the NEDOCS (National Emergency Department Overcrowding Scale) criterion. The severity of the disease was also evaluated based on the level of the triage of patients through the Emergency Severity Index (ESI) system and vital signs.Results: With each year increase in age, the chance of short-term mortality increases by 0.8%. People with O2 sat% <90% are 7.3 times more likely to experience short term mortality in an emergency department compared to people with O2 sat%> 90%. A significant relationship was noted between short term mortality and SBP (systolic blood pressure) in the hospital's emergency department. It was also found out that as the triage score increases, short term mortality decreases significantly. As hospital stay increases, the chance of the patients' mortality decreases by 0.5%.Conclusion: The percentage of arterial blood oxygen saturation, systolic blood pressure, respiration rate per minute, triage score, the way the patient arrives at the hospital, working shifts, hospitalization duration, age, and comorbidities were regarded as the risk factors for short term mortality. Therefore, promoting professional knowledge and skills of nurses and physicians in the hospitals' emergency department and up-to-dating and reviewing emergency protocols as well as similar research can greatly help reduce short term mortality in the hospital's emergency department.

Abstract Introduction: Intracranial hemorrhage is a devastating complication of cancer and its treatment.Objective: To evaluate the characteristic, risk factors and clinical outcomes in cancer patients with intracranial hemorrhage presenting to the emergency department. Methods: We collected a decade of retrospective data on all patients with the diagnosis of ICH who visited The University of Texas MD Anderson Cancer Center emergency department. Logistic regression analyses were used to determine the association between clinical variables and various outcomes.Results: 704 confirmed acute ICH cases were identified. Of these, 576 (81.8%) were spontaneous. In-hospital, 7-day, and 30-day mortality rates were 15.1%, 11.4%, and 25.6%, respectively. Hypertension was most predictive of prolonged hospital stay ( [OR]=4.77, 95% [CI]=1.30-22.70, P=0.045) and intensive care unit admission (OR=1.52, 95% CI=1.09-2.12, P=0.013). Low platelet count was associated with both in-hospital mortality (OR=0.96, 95% CI=0.94-0.99, P=0.008) and 30-day mortality (OR=0.98, 95% CI=0.96-1.00, P=0.016). Radiologic findings especially herniation and hydrocephalus, were strong predictors of short-term mortality. Patients with intratumor bleeding had substantially lower short-term mortality rates, but this did not reach statistical significance.Conclusions: Intracranial hemorrhage remains an uncommon complication in cancer patients. The risk factors most helpful in predicting outcomes were hypertension, low platelet count, and hydrocephalus or herniation on imaging.

Introduction: Risk factors comprising the CHA2DS2VASc score are recognized as risk factors for venous thromboembolism and mortality in COVID-19 patients. A modified CHA2DS2VASc score (M-CHA2D2VASc), developed by changing gender criteria from female to male, has been proposed to predict in-hospital mortality in COVID-19 patients. The aim of this study was to evaluate the prognostic accuracy of M-CHA2D2VASc for adverse clinical outcomes and short-term mortality in COVID-19 patients admitted to the Emergency Department.Material and Methods: Retrospective study of patients admitted to the ED who underwent computed tomography pulmonary angiography due to suspected pulmonary embolism or clinical worsening. Patients were stratified into three M-CHA2DS2-VASc risk-categories: low (0 - 1 points), intermediate (2 - 3 points) and high-risk (≥ 4 points).Results: We included 300 patients (median age 71 years, 59% male). The overall mortality was 27%. The M-CHA2DS2-VASc score was higher in non-survivors compared to survivors [4 (IQR:3 - 5) vs 2 (IQR: 1 - 4), respectively, p < 0.001). The M-CHA2DS2-VASc score was identified as an independent predictor of mortality in a multivariable logistic regression model (OR 1.406, p = 0.007). The Kaplan-Meier survival curves showed that the M-CHA2DS2-VASc score was associated with short-term mortality (log-rank test < 0.001), regardless of hospitalization (log-rank test p < 0.001 and p = 0.007, respectively). The survival proportion was 92%, 80% and 63% in the lower, intermediate, and higher risk-groups. As for the risk-categories, no difference was found in pulmonary embolism, Intensive Care Unit admission, and invasive mechanical ventilation.Discussion: This is the first study to validate M-CHA2DS2-VASc score as a predictor of short-term mortality in patients admitted to the Emergency Department.Conclusion: The M-CHA2DS2-VASC score might be useful for prompt risk-stratification in COVID-19 patients during admission to the Emergency Department.

Deletion of long arm of chromosome 20 (del(20q)) is commonly observed in myelodysplastic syndromes (MDS). Reduced expression of genes located within the common deleted region (CDR) of del(20q) due to haploinsufficiency may play a role in molecular pathogenesis of MDS. In the previous study, we examined expression of genes located within the CDR which we determined using array-CGH, in bone marrow mononuclear cells in MDS patients with or without del(20q), indicating that BCAS4 expression was significantly reduced in bone marrow cells in MDS patients with or without del(20q). The BCAS4 gene, which was identified as a fusion transcript expressed in MCF7 cells, encodes 23kD protein. Although function of BCAS4 protein remains unclear, it could be a member of "cappuccino" family, which belong to lysosome-related organelles. Abnormality of genes encoding lysosome-related organelles cause variety of congenital disorders, including the Hermansky-Pudlak syndromes, which is characterized by oculocutaneous albinism and bleeding tendency due to platelet dysfunction as a result of lysosome abnormalities. In the present study we investigated clinical implication of BCAS4 expression level in MDS patients. Mononuclear cells separated from bone marrow samples taken at the time of MDS diagnosis were used for analysis. Written informed consent was obtained from patients before study. To analyze BCAS4 expression, quantitative RT-PCR was performed using cDNA from mononuclear cells as template by the TaqMan probe method (Applied Biosystems) with co-amplification of the endogenous control gene, human GAPDH (Applied Biosystems). Samples from 103 MDS patients, 64 males and 39 females with median age of 67 years (range: 20-91 years), with (n=14) or without (n=89) del(20q), were examined in the present study. Patients were classified as RCUD (n=12), RCMD (n=55), RARS (n=9), RAEB-1 (n=10), and RAEB-2 (n=13), according to WHO 2008 classification, and in RAEB-T (n=4) according to FAB classification. They also were categorized in four IPSS risk groups, low risk (n=30), intermediate-1 risk (n=46), intermediate-2 risk (n=18), and high risk (n=9). There was no significant difference in relative BCAS4 expression level between patients with del(20q) and those without del(20q), and among WHO subtypes. Higher IPSS risk groups (INT-2 and High) showed trend in association with reduced BCAS4 expression compared with lower IPSS risk groups (Low and INT-1) (P=0.104). We analyzed impact of BCAS4 expression on overall survival (OS). Based on BCAS4 expression level, 103 patients were divided into four groups, highest (Q1), intermediate (Q2, Q3), and lowest (Q4) quartiles. The Kaplan-Meier analysis demonstrated that Q4 showed significantly worse OS compared with remaining quartiles (Q1-Q3) (log-rank test, P=0.0031). The estimated 2-year OS rates in Q1-3 group and Q4 group were 75.1% and 48.9%, respectively. According to the COX proportional hazards model, univariate analysis showed lower BCAS4 expression (Q4 vs Q1-Q3) was associated with worse OS (hazard ratio 3.43, 95%CI 1.89-6.11, P=0.0001) as well as older age (65 years or older vs less than 65 years), and higher IPSS risk groups (INT-2 and High vs Low and INT-1). Multivariate analysis indicated that lower BCAS4 expression showed trend for association with worse OS (hazard ratio 1.90, 95%CI 0.96-3.64, P=0.0651) by analyzing with two variables (older age and higher IPSS groups). Next, we investigated whether OS is predicted by combination of three variables, BCAS4 expression level, IPSS risk groups, and age at diagnosis. We defined lower BCAS4 expression (Q4), higher IPSS (INT-2 and High), and older age (65 years or older), as risk factors. The Kaplan-Meier analysis showed that survival curves were well separated according to number of risk factors (0, 1, and 2 or more) (P<0.0001). The estimated 1-year, 2-year, and 5-year survival rates were 100%, 100%, and 86.5% in patients without risk factor, 75%, 70.2%, and 51.7% in patients with one risk factor, and 54%, 34.3%, and 11.4% in patients with two or more risk factors. The present study demonstrated that reduced BCAS4 expression is associated with inferior clinical outcome, indicating that BCAS4 expression level could be a useful prognostic marker in MDS, especially by combination with IPSS risk and patients age at diagnosis.
