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.

OBJECTIVE: Few studies investigating associations between fine particulate air pollution and hemorrhagic stroke have considered subtypes. Additionally, less is known about the modification of such association by factors measured at the individual level. We aimed to investigate the risk of fatal intracerebral hemorrhage (ICH) incidence in case of PM (particles ≤ 2.5 μm in aerodynamic diameter) exposure. METHODS: Data on incidence of fatal ICH from 1 June 2012 to 31 May 2014 were extracted from the acute stroke mortality database in Shanghai Municipal Center for Disease Control and Prevention (SCDC). We used the time-stratified case-crossover approach to assess the association between daily concentrations of PM and fatal ICH incidence in Shanghai, China. RESULTS: A total of 5286 fatal ICH cases occurred during our study period. The averaged concentration of PM was 77.45 μg/m. The incidence of fatal ICH was significantly associated with PM concentration. Substantial differences were observed among subjects with diabetes compared with those without; following the increase of PM in lag2, the OR (95% CI) for subjects with diabetes was 1.26 (1.09-1.46) versus 1.05 (0.98-1.12) for those without. We did not find evidence of effect modification by hypertension and cigarette smoking. CONCLUSIONS Fatal ICH incidence was associated with PM exposure. Our results also suggested that diabetes may increase the risk for ICH incidence in relation to PM.

Rotational thromboelastometry (ROTEM) is a point-of-care viscoelastic method and enables to assess viscoelastic profiles of whole blood in various clinical settings. ROTEM-guided bleeding management has become an essential part of patient blood management (PBM) which is an important concept in improving patient safety. Here, ROTEM testing and hemostatic interventions should be linked by evidence-based, setting-specific algorithms adapted to the specific patient population of the hospitals and the local availability of hemostatic interventions. Accordingly, ROTEM-guided algorithms implement the concept of personalized or precision medicine in perioperative bleeding management (‘theranostic’ approach). ROTEM-guided PBM has been shown to be effective in reducing bleeding, transfusion requirements, complication rates, and health care costs. Accordingly, several randomized-controlled trials, meta-analyses, and health technology assessments provided evidence that using ROTEM-guided algorithms in bleeding patients resulted in improved patient's safety and outcomes including perioperative morbidity and mortality. However, the implementation of ROTEM in the PBM concept requires adequate technical and interpretation training, education and logistics, as well as interdisciplinary communication and collaboration.

BACKGROUND: Preterm infants have difficulty maintaining body temperature after birth. However, clinical guidelines advocate that neonatal body temperature should be maintained at 36.5°C–37.5°C. PURPOSE: We aimed to investigate the incidence of admission hypothermia in very low birth weight (VLBW) infants and to determine the association of admission temperature with in-hospital mortality and morbidities. METHODS: A cohort study using prospectively collected data involving 70 neonatal intensive care units (NICUs) that participate in the Korean Neonatal Network. From registered infants born between January 2013 and December 2015, 5,343 VLBW infants born at less than 33 weeks of gestation were reviewed. RESULTS: The mean admission temperature was 36.1°C±0.6°C, with a range of 31.9°C to 38.4°C. Approximately 74.1% of infants had an admission hypothermia of <36.5°C. Lower birth weight, intubation in the delivery room and Apgar score <7 at 5 minutes were significantly related to admission hypothermia. The mortality was the lowest at 36.5°C–37.5°C and adjusted odd ratios for all deaths increased to 1.38 (95% confidence interval [CI], 1.04–1.83), 1.44 (95% CI, 1.05–1.97) and 1.86 (95% CI, 1.22–2.82) for infants with admission temperatures of 36.0°C–36.4°C, 35.0°C–35.9°C, and <35.0°C, respectively. Admission hypothermia was also associated with high likelihoods of bronchopulmonary dysplasia, pulmonary hypertension, proven sepsis, pulmonary hemorrhage, air-leak, seizure, grade 3 or higher intraventricular hemorrhage and advanced retinopathy of prematurity requiring laser therapy. CONCLUSION: A large portion of preterm infants in Korea had hypothermia at NICU admission, which was associated with high mortality and several important morbidities. More aggressive interventions aimed at reducing hypothermia are required in this high-risk population.

Hemodynamically significant preterm patent ductus arteriosus (PDA) affects mortality; comorbidities such as necrotizing enterocolitis, intraventricular hemorrhage, and bronchopulmonary dysplasia; and adverse long-term neurodevelopmental outcomes in preterm infants, particularly in very low birth weight infants. However, recent studies have indicated that there is no consensus on the causal relationship between PDA and neonatal outcomes, the benefit of PDA treatment, the factors guiding the need for treatment, and optimal treatment strategies. Such uncertainty has resulted in wide variations in practice for treating preterm PDA between units, regions, and nations. Nowadays, there has been a paradigm shift to more conservative treatment for preterm PDA, and suggestions regarding selective management of preterm PDA considering risk factors and hemodynamic significance are increasing. Neonatologist-performed echocardiography and advances in modalities to assess hemodynamic significance such as biologic markers and near-infrared spectroscopy also help improve the efficacy of selective treatment of preterm PDA.

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.
