BACKGROUND AND OBJECTIVE

A growing body of evidence supports that inflammatory mechanisms are involved in secondary brain injury after intracerebral hemorrhage (ICH) which has implications on the morbidity and mortality of stroke patients. Neutrophil-to-lymphocyte ratio (NLR) is a comprehensive index marker of inflammation and immune status of a patient. The prognostic value of NLR in predicting in-hospital mortality and functional outcome of patients with spontaneous intracerebral hemorrhage will be assessed in this study.

We retrospectively selected 151 hemorrhagic stroke patients, and demographic and clinical characteristics were collected and computed for NLR. Receiver operating characteristic analysis using Youden’s index was utilized to determine the NLR cut-off value with the best sensitivity and specificity. The association of NLR with the inhospital mortality and functional outcome was assessed using Logistic regression analysis. Pearson Product Model Correlation was employed to evaluate the correlation of NLR with ICH volume.

Admission NLR >7 showed a significant association (p = <0.001 OR 7.99) with in-hospital mortality with a sensitivity of 70.83% and specificity of 72.82%. Furthermore, computed NLR of more than 6.4 showed significant association (p = 0.040 OR 2.92) with poor functional outcome. However, our study revealed that admission NLR showed a low level of correlation (r=0.2968, p=0.002) with the volume of ICH.

This study demonstrated that ICH patients with an elevated NLR is associated with increased inhospital mortality and poor functional outcome and that NLR can be used to predict clinical outcome among patients with spontaneous ICH.

BACKGROUND

There is ambiguity on antiplatelet therapy for post-transcatheter aortic valve replacement (TAVR) patients for stroke prevention, but dual antiplatelet therapy (DAPT) is routinely started despite lack of data on effectiveness and bleeding safety of DAPT versus single antiplatelet therapy (SAPT). This study aims to determine the effectiveness of DAPT versus SAPT in stroke prevention and assess bleeding safety.

A systematic search was done for randomized clinical trials involving DAPT and SAPT in patients who underwent TAVR. The primary outcome was stroke after 1 year of either DAPT and SAPT and life-threatening bleeding. Secondary end points included all-cause mortality. Trials were identified through systematic searches on the following databases (November 2019): Cochrane, MEDLINE, and Google Scholar and ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform. Risk ratio was used for dichotomous outcomes. Heterogeneity among the studies for the meta-analysis was detected using a χ2 test (0.01 level of significance). Risk-of-bias assessment was done.

There is a lower incidence of stroke in patients on DAPT, but with a higher incidence of life-threatening bleeding and major bleeding. There is also a lower incidence of all-cause mortality in SAPT. The statistical power of this meta-analysis is low due to small population size.

Single antiplatelet therapy is comparable to DAPT in preventing stroke with the added benefit of a lower incidence of life-threatening and major bleeding and a lower incidence of all-cause mortality.

mortality.RESULTS: During the therapeutic period, there were no significant differences between the groups in the proportion of composite events, recurrence, or clinically relevant bleeding. Multivariate analysis using the Cox proportional hazards model also showed no significant difference in the number of composite events and clinically relevant bleeding between the groups. In the rivaroxaban group, 44.0% of patients experienced gastrointestinal bleeding and 24.0% experienced urinary tract bleeding. In the dalteparin group, bleeding was most common in the urinary tract (44.4%) and at the injection site (22.2%).CONCLUSION: In this study, although there were no significant differences in effectiveness or safety between the rivaroxaban and dalteparin groups, rivaroxaban use was associated with a higher rate of clinically relevant bleeding than dalteparin. Therefore, caution should be taken when prescribing rivaroxaban for gynecologic cancer-associated VTE and bleeding events should be carefully monitored.]]>

mortality.RESULTS: A total of 455 strains were isolated from 432 ascitic culture samples. Gram-negative bacteria (GNB), gram-positive bacteria (GPB), and fungi caused 52.3, 45.5, and 2.2% of all SAI episodes, respectively. Episodes were classified as nosocomial (41.2%), healthcare-related (34.7%), and community-acquired (24.1%). Escherichia coli (13.4%) and Klebsiella pneumoniae (2.4%) were extended-spectrum β-lactamase producing isolates. The prevalence of methicillin-resistant Staphylococcus aureus was 1.1%. Ceftazidime, cefepime, aztreonam, and amikacin were recommended as first-line antibiotics agents for non-MDR GNB infections; piperacillin/tazobactam and carbapenems for MDR GNB in community-acquired and healthcare-related or nosocomial infections, respectively; and vancomycin or linezolid for GPB infections, regardless of drug-resistance status. Multivariate analysis revealed days of hospital stay before SAI, upper gastrointestinal bleeding, white blood cell count, alanine aminotransferase, serum creatinine concentration, total bilirubin, and international normalized ratio as key independent predictors of 28-day mortality.CONCLUSION: MDR pathogens and antibiotic strategies were identified in patients with acute decompensated cirrhosis with culture-positive SAI, which may help optimize therapy and improve clinical outcomes.]]>

Background: Subarachnoid hemorrhage is a devastating type of stroke with high mortality rate. The understanding of factors that contribute to mortality in patient with subarachnoid hemorrhage can help clinicians in further management of the patients. Aim: The aim of this study is to identify mortality risk factors in patients with subarachnoid hemorrhage (SH). Methods: This study is a retrospective cohort study. Data were obtained from the stroke registry and medical records of patients at Bethesda Hospital Yogyakarta. Data were analyzed using univariate, bivariate and multivariate logistic regression analysis. Results: Data were obtained from 80 subarachnoid hemorrhage patients consisting of 40 males (50%) and 40 females (50%). Result of multivariate analysis show that there are significant associations between mortality in SAH patient with loss of consciousness (OR: 19.722, 95% CI: 1.788- 217.521, p: 0.015), elevated systolic blood pressure (OR: 157.4, 95%CI: 2.068- 11990.9, p: 0.022), high random blood glucose (OR: 12.457, 95%CI: 2.305- 67.322, p: 0.03) and presence of medical complication (OR: 30.539, CI95%: 2.685- 347.377, p: 0.006). Conclusion This study demonstrated that loss of consciousness, elevated systolic blood pressure, high blood glucose, and presence of medical complication has significant association with mortality of SAH patient.

PURPOSE: Although carotid endarterectomy (CEA) is recommended as a treatment for carotid stenosis rather than carotid artery stenting (CAS), CAS has been preferred in Korea. The aim of this study was to analyze long-term outcomes after CAS compared with CEA using Korean nationwide insurance data. MATERIALS AND METHODS: We obtained all data from the nationwide database of the Health Insurance Review & Assessment Service (HIRA) during the study period using several codes regarding the procedure or operation. We included the HIRA data, which included at least one-year follow-up after the procedures. The outcomes associated with both procedures were death, recurrence of ischemic stroke, and admission for cerebral hemorrhage. RESULTS: A total of 16,065 eligible patients who were treated with CAS or CEA between 1 January 2007 and 31 December 2016 were analyzed. The number of patients with CAS and CEA was 12,173 (75.8%) and 3,892 (24.2%), respectively. 8,976 patients (55.9%) were classified as symptomatic patients. CAS was associated with a higher risk of all-cause mortality (adjusted hazard ratio [HR], 1.282; 95% confidence interval [CI], 1.173–1.400). The adjusted rates for recurrent ischemic stroke and cerebral hemorrhage between CAS versus CEA were 24.9% versus 15.9% (HR, 1.474; 95% CI, 1.325–1.639) and 1.5% versus 0.9% (HR, 2.026; 95% CI, 1.322–3.106), respectively. In young symptomatic patients, there was no statistically significant difference in all-cause mortality and cardiovascular death between CAS and CEA. CONCLUSION: Our study using Korean nationwide insurance data demonstrated similar results to previous studies. Until further evidence of CAS is established through prospective studies, CAS should be performed in selected patients according to current guidelines.

PURPOSE: To evaluate superiority of a night float (NF) system in comparison to a traditional night on-call (NO) system for surgical residents at a single institution in terms of efficacy, safety, and satisfaction. METHODS: A NF system was implemented from March to September 2017 and big data analysis from electronic medical records was performed for all patients admitted for surgery or contacted from the emergency room (ER). Parameters including vital signs, mortality, and morbidity rates, as well as promptness of response to ER calls, were compared against a comparable period (March to September 2016) during which a NO system was in effect. A survey was also performed for physicians and nurses who had experienced both systems. RESULTS: A total of 150,000 clinical data were analyzed. Under the NO and NF systems, a total of 3,900 and 3,726 patients were admitted for surgery. Mortality rates were similar but postoperative bleeding was significantly higher in the NO system (0.5% vs. 0.2%, P = 0.031). From the 1,462 and 1,354 patients under the NO and NF systems respectively, that required surgical consultation from the ER, the time to response was significantly shorter in the NF system (54.5 ± 70.7 minutes vs. 66.8 ± 83.8 minutes, P < 0.001). Both physicians (90.4%) and nurses (91.4%) agreed that the NF system was more beneficial. CONCLUSION: This is the first report of a NF system using big data analysis in Korea, and potential benefits of this new system were observed in both ward and ER patient management.

mortality of trauma patients with severe hemorrhage.METHODS: Seventeen relevant articles were obtained by searching the PubMed databases through February 15, 2019. The estimated mortality rates and injury severity scores were obtained through a meta-analysis. In addition, diagnostic test accuracy (DTA) reviews were conducted to obtain the sensitivity, specificity, diagnostic odds ratio, and the summary receiver operating characteristic curve.RESULTS: At 24 hours, the estimated mortality rates were 0.194, 0.126, and 0.168 in assessments using MT, CAT, and RI, respectively. In addition, the pooled sensitivity of CAT (0.89; 95% confidence interval [CI], 0.82–0.94) was significantly higher than that of MT (0.63; 95% CI, 0.57–0.68) and RI (0.69; 95% CI, 0.63–0.75). Overall, the pooled specificity of MT and CAT was 0.82 (95% CI, 0.80–0.83) and 0.85 (95% CI, 0.83–0.88), respectively, while the pooled sensitivity was 0.49 (95% CI, 0.44–0.54) and 0.50 (95% CI, 0.38–0.62), respectively.CONCLUSION: CAT may be a more sensitive predictor for 24-hour mortality than other predictors. Furthermore, RI also appears to be a useful predictor for 24-hour mortality. Both MT and CAT showed high specificity for overall mortality.]]>

BACKGROUND: The anatomy of middle cerebral artery (MCA) aneurysms has been noted to be unfavorable for endovascular treatment. The purpose of this study was to assess the feasibility and efficacy of coiling for MCA aneurysms.METHODS: From January 2004 to December 2015, 72 MCA aneurysms (38 unruptured and 34 ruptured) in 67 patients were treated with coils. Treatment-related complications, clinical outcomes, and immediate and follow-up angiographic outcomes were retrospectively analyzed.RESULTS: Aneurysms were located at the MCA bifurcation (n=60), 1st segment (M1, n=8), and 2nd segment (M2, n=4). Sixty-nine aneurysms (95.8%) were treated by neck remodeling techniques using multi-catheter (n=44), balloon (n=14), stent (n=8), or combination of these (n=3). Only 3 aneurysms were treated by single-catheter technique. Angiographic results were 66 (91.7%) complete, 5 (6.9%) remnant neck, and 1 (1.4%) incomplete occlusion. Procedural complications included aneurysm rupture (n=1), asymptomatic coil migration to the distal vessel (n=1), and acute thromboembolism (n=10) consisting of 8 asymptomatic and 2 symptomatic events. Treatment-related permanent morbidity and mortality rates were 4.5% and 3.0%, respectively. There was no bleeding on clinical follow-up (mean, 29 months; range, 6-108 months). Follow-up angiographic results (mean, 26 months; range, 6-96 months) in patients included 1 major and 3 minor recanalizations.CONCLUSION: Coiling of MCA aneurysms could be a technically feasible and clinically effective treatment strategy with acceptable angiographic and clinical outcomes. However, the safety and efficacy of this technique as compared to surgical clipping remains to be ascertained.

During pregnancy, the procoagulant activity increases (manifested by elevation in factor VII, factor VIII, factor X, and fibrinogen levels), while the anticoagulant activity decreases (characterized by reduction in fibrinolysis and protein S activity), resulting in hypercoagulation. Standard coagulation tests, such as prothrombin time or activated partial thromboplastin time, are still used despite the lack of evidence supporting its accuracy in evaluating the coagulation status of pregnant women. Thromboelastography and rotational thromboelastometry, which are used to assess the function of platelets, soluble coagulation factors, fibrinogen, and fibrinolysis, can replace standard coagulation tests. Platelet count and function and the effect of anticoagulant treatment should be assessed to determine the risk of hematoma associated with regional anesthesia. Moreover, anesthesiologists should monitor patients for postpartum hemorrhage (PPH), and attention should be paid when performing rapid coagulation tests, transfusions, and prohemostatic pharmacotherapy. Transfusion of a high ratio of plasma and platelets to red blood cells (RBCs) showed high hemostasis success and low bleeding-related mortality rates in patients with severe trauma. However, the effects of high ratios of plasma and platelets and the ratio of plasma to RBCs and platelets to RBCs in the treatment of massive PPH were not established. Intravenous tranexamic acid should be administered immediately after the onset of postpartum bleeding. Pre-emptive treatment with fibrinogen for PPH is not effective in reducing bleeding. If fibrinogen levels of less than 2 g/L are identified, 2–4 g of fibrinogen or 5–10 ml/kg cryoprecipitate should be administered.
