[PMID: 35578847 DOI: 10.2174/1567202619666220516145120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Revised: 02/17/2022] [Accepted: 02/23/2022] [Indexed: 01/27/2023]
Abstract
OBJECTIVE In this study, we investigated the relationship between serum ischemic modified albumin (IMA) levels and other hematologic features and middle cerebral artery (MCA) severe stenosis/occlusion in acute ischemic stroke (AIS) patients. METHODS The levels of serum IMA and Albumin (ALB) of 169 AIS patients were measured, and the ratio of IMA to albumin (IMAR) and the albumin-adjusted ischemia-modified albumin index (IMA index) were calculated. Different combinations of other hematologic changes and clinical features of the patients were analyzed. RESULTS The results indicated that the levels of blood IMA and IMAR were significantly higher in the group with severe intracranial stenosis/occlusion than in the group with non-severe stenosis/ occlusion in AIS patients, while the CHE levels were significantly lower than those in the other groups. In the MCA severe stenosis/occlusion group, the levels of blood IMA and IMAR were significantly higher than that in the other vascular severe stenosis/occlusion groups, while the IMA index, ALB, and CHE were significantly lower than that in the other groups. Multiple linear regression analysis showed a significant negative correlation between IMA and albumin. A combined diagnostic ROC curve analysis showed that among AIS patients, the best combination for determining severe stenosis/occlusion of the great intracranial arteries was the admission NIHSS score + CHE (AUC = 0.783). The best combination for determining severe stenosis or occlusion of the MCA in AIS patients was IMAR combined with the admission NIHSS score and CHE (AUC = 0.827). CONCLUSION The combined use of IMA, IMAR, and the IMA index has some diagnostic value in AIS caused by severe stenosis or occlusion of the MCA. IMAR, CHE, and the admission NIHSS scores are the best combinations to determine whether an AIS patient has severe stenosis or occlusion of the MCA.

The Safety and Efficacy of Endovascular Treatment in Acute Ischemic Stroke Patients Caused by Large-Vessel Occlusion with Different Etiologies of Stroke: Data from ANGEL-ACT Registry. Neurotherapeutics 2022; 19:501-512. [PMID: 35243592 PMCID: PMC9226213 DOI: 10.1007/s13311-022-01189-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/13/2022] [Indexed: 11/25/2022] Open
Abstract
This study aimed to investigate the safety and efficacy of endovascular treatment (EVT) in acute ischemic stroke (AIS) patients caused by large-vessel occlusion (LVO) with different etiologies of stroke. A total of 928 AIS patients were assigned into intracranial atherosclerotic stenosis (ICAS)-LVO, cardioembolic (CE)-LVO, and artery to artery embolism (ATA)-LVO groups. The safety and efficacy endpoints were symptomatic intracranial hemorrhage (SICH) at 24 h after EVT, 90-day favorable outcomes (modified Rankin Scale (mRS) of 0-2), successful recanalization (modified thrombolysis in cerebral infarct (mTICI) 2b/3), and complete recanalization (mTICI 3). The logistic regression analysis was used to determine the associations between the safety and efficacy endpoints. There were 305 (32.9%), 535 (57.6%), and 88 (9.5%) patients in ICAS-LVO, CE-LVO, and ATA-LVO groups, respectively. No significant difference was found in the 90-day mRS and successful recanalization among the three groups. However, compared with the ICAS-LVO group, complete recanalization rate was higher in the CE-LVO (adjusted odds ratio, 4.50; 95% confidence interval (CI), 2.37-8.56) and ATA-LVO groups (aOR, 2.43; 95% CI, 1.16-5.10). The results of subgroup analysis showed a significant association between CE-LVO stroke etiology and complete recanalization in the age population < 65 years old (aOR, 14.33; 95% CI, 4.39-46.79, P = 0.019). Functional outcomes were similar among different etiologies of stroke. CE-LVO and ATA-LVO could be related to a higher rate of complete recanalization, and there was a trend of the increased risk of parenchymal hemorrhage in the CE-LVO group.

Abstract
Cerebrovascular disease is the leading cause of long-term disability in the world and the third-leading cause of death in the United States. The early diagnosis of transient ischemic attack (TIA) is of great importance for reducing the mortality and morbidity of cerebrovascular diseases. Patients with TIA have a high risk of early subsequent ischemic stroke and the development of permanent nervous system lesions. The diagnosis of TIA remains a clinical diagnosis that highly relies on the patient's medical history assessment. There is a growing list of biomarkers associated with different components of the ischemic cascade in the brain. In this review, we take a closer look at the biomarkers of TIA and their validity with a focus on the more clinically important ones using recent evidence of their reliability for practical usage.

Endovascular Treatment in Acute Ischemic Stroke with Large Vessel Occlusion According to Different Stroke Subtypes: Data from ANGEL-ACT Registry. Neurol Ther 2021; 11:151-165. [PMID: 34800279 PMCID: PMC8857367 DOI: 10.1007/s40120-021-00301-z] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Accepted: 11/03/2021] [Indexed: 12/08/2022] Open
Abstract
Introduction Endovascular treatment’s (EVT) safety and efficacy have been proven in treating acute ischemic stroke (AIS) due to large vessel occlusion (LVO). However, limited data exist in different stroke subtypes. We aimed to investigate the differences in efficacy and safety of EVT for acute LVO according to different stroke subtypes. Methods A total of 1635 AIS patients with LVO undergoing EVT from a prospective cohort of the Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke (ANGEL-ACT) registry were classified into three types according to the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) criteria. We compared the primary outcome: 90-day modified Rankin Scale (mRS) score, the secondary outcomes: 90-day mRS (0–1, 0–2, and 0–3), successful recanalization (mTICI 2b/3), and complete recanalization (mTICI 3), and the safety outcomes: death within 90 days, parenchymal hemorrhage (PH), and symptomatic intracranial hemorrhage (SICH) among the three subtypes of stroke patients. Then, multivariable logistic regression models adjusting for potential baseline-confounding variables to determine the associations between stroke subtypes and safety and efficacy endpoints were performed. Finally, we performed subgroup analyses to explore discrepancies in the relationships. Results EVT of cardioembolic LVO (CE-LVO) had a higher rate of mTICI 3 (71.7% vs. 65.9% and 63.2%; P = 0.024) and a higher rate of PH (13.8% vs. 5.4% and 6.7%; P < 0.001) when compared to other stroke subtypes. Even multivariable analysis demonstrated that CE-LVO was associated with mTICI 3 [adjusted odds ratio (OR), 1.50 (95% CI 1.04–2.17)] and PH [adjusted OR, 1.97 (95% CI 1.09–3.55)]. However, the 90-day mRS distribution and 90-day mRS (0–1, 0–2, and 0–3) did not differ among the stroke subtypes, and nor did the SICH (P > 0.05). Conclusions Functional outcomes were similar among different stroke subtypes. Despite a higher rate of complete recanalization, there is an increased risk of parenchymal hemorrhage in CE-LVO. Trial Registration Clinical trial registration number: NCT03370939.

Abstract
Ischemic stroke is one of the main causes of physical disability and mortality worldwide. Long non-coding RNAs (lncRNAs) are reported to be dysregulated in various biological progressions and serve important roles in pathological processes of cerebral ischemia. However, their biological actions and potential mechanisms in the progression of ischemic stroke remain unknown. The present study aimed to investigate the functions of LINC00319 on ischemic brain injury. It was identified that LINC00319 was significantly upregulated in the Gene Expression Omnibus profile of ischemic stroke. Furthermore, LINC00319 overexpression elevated caspase-3 activity and increased the apoptotic rate of neuronal cells, as well as decreased cell viability and glucose uptake. It was also demonstrated that LINC00319 participated in oxygen-glucose deprivation (OGD)-induced cerebral ischemic injury. LINC00319 could competitively bind with microRNA (miR)-200a-3p and decrease its expression. Moreover, miR-200a-3p could partly offset the negative effects of LINC00319 overexpression on neuronal injury caused by OGD. Collectively, the present results suggested that LINC00319 promoted apoptosis and aggravated neuronal injury induced by OGD by regulating miR-200a-3p, which may be important for ischemic stroke treatment.

Integrative Analysis of MAPK14 as a Potential Biomarker for Cardioembolic Stroke. BIOMED RESEARCH INTERNATIONAL 2020; 2020:9502820. [PMID: 32879891 PMCID: PMC7448239 DOI: 10.1155/2020/9502820] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/29/2020] [Revised: 07/09/2020] [Accepted: 07/15/2020] [Indexed: 01/22/2023]
Abstract
The aim of this study was to obtain the candidate genes and biomarkers that are significantly related to cardioembolic stroke (CS) by applying bioinformatics analysis. In accordance with the results of the weighted gene coexpression network analysis (WGCNA) in the GSE58294 dataset, 11 CS-related coexpression network modules were identified in this study. Correlation analysis showed that the black and pink modules are significantly associated with CS. A total of 18 core genes in the black module and one core gene in the pink module were determined. We then identified differentially expressed genes (DEGs) of CS at 3 h, 5 h, and 24 h postonset. After performing intersection, it was found that 311 genes were coexpressed at these three time points. These genes were majorly enriched in positive regulation of transferase activity and regulation of peptidase activity. The abovementioned coexpressed DEGs were subjected to protein-protein interaction analysis and subnetwork module analysis. Subsequently, we used cytoHubba to obtain 11 key genes from DEGs. The intersection of the core genes screened from WGCNA and the key genes selected from DEGs yielded the MAPK14 gene. The expression level of MAPK14 on the receiver operating characteristic (ROC) curves of CS at 3 h, 5 h, and 24 h showed that the area under the ROC curve (AUC) was 0.923, 0.934, and 0.941, respectively. In a nutshell, MAPK14 screened out by using WGCNA showed differential expression in CS. We conclude that MAPK14 can be used as a potential biological marker of CS and exhibits potential to predict the physiopathological condition of CS patients.

Abstract
OBJECTIVE The aim of the present study is to confirm the correlation between fibrinogen and the severity of cerebral white matter hyperintensities (WMHs) among nondiabetic patients with noncardiogenic acute ischemic stroke. PATIENTS AND METHODS A cross-sectional study of 170 consecutive patients with noncardiogenic acute ischemic stroke who underwent magnetic resonance imaging and vascular imaging was conducted. WMHs were classified into periventricular hyperintensity (PVH) and deep and subcortical WMH (DSWMH) using Fazekas rating scale. After adjustment for fibrinogen and other vascular risk factors, we determined which factors were independent of WMHs. RESULTS After adjustment for the vascular risk factors, prior ischemic stroke (odds ratio [OR] 4.153, 95% confidence interval [CI] 1.077-16.020, P = .039), fibrinogen level (OR 2.114, 95% CI 1.034-4.322, P = .040), and glycosylated hemoglobin A1c (OR .633, 95% CI .423-.947, P = .026) were independently and positively associated with PVH (P < .05); prior ischemic stroke (OR 2.841, 95% CI 1.469-5.493, P = .002), lipoprotein(a) (OR 1.002, 95% CI 1.000-1.005, P = .047), and fibrinogen levels (OR 1.788, 95% CI 1.170-2.732, P = .007) were independently and positively associated with DSWMH (P < .05). CONCLUSIONS Our study demonstrated that prior ischemic stroke and higher fibrinogen are associated with WMHs, regardless of PVH and DSWMH, in nondiabetic patients with noncardiogenic acute ischemic stroke. In addition, lipoprotein(a) might be an independent predictor of DSWMH in patients with noncardiogenic acute ischemic stroke.

Abstract
To determine differences in 90-day mortality and identify risk factors among different etiological classifications of ischemic stroke using the Trial of ORG 10172 in Acute Stroke Treatment (TOAST) classification.Our retrospective analysis included 538 ischemic stroke patients. The cause of stroke was categorized according to the TOAST criteria, and 90-day mortality rates were obtained through the patient follow-up. Age, sex, previous medical history, and clinical features were used in the analysis of potential risk factors.There were 38 deaths during the 90-day follow-up period. Patients in the undetermined cause subgroups experienced significantly higher mortality rate than those in subgroups with small artery occlusion and large artery atherosclerosis. Factors independently associated with 90-day mortality for patients with the large artery atherosclerosis stroke subtype were age (95% confidence interval [CI], 1.010-1.192, P = .028), history of hypertension (95% CI, 3.030-99.136, P = .001), high blood glucose (95% CI, 1.273-2.354, P < .001), high cholesterol (95% CI, 0.017-0.462, P = .004), high uric acid (95% CI, 2.360-64.389, P = .003), and National Institute of Health Stroke Scale(95% CI, 1.076-1.312, P = .001). Age (95% CI, 1.012-1.358, P = .034) and high cholesterol (95% CI, 0.011-0.496, P = .007) were independently associated with 90-day mortality for patients with the small artery occlusion subtype of stroke.Our analysis identified that certain risk factors and 90-day mortality differ significantly among different stroke subtypes, as classified by the TOAST criteria. These risk factors must be considered carefully to provide the best clinical management of these patients and thus reduce mortality.

Abstract
This study was aimed to identify and evaluate the International Classification of Functioning (ICF) key codes for dysphagia in stroke patients. Thirty patients with dysphagia after stroke were enrolled in our study. To evaluate the ICF dysphagia scale, 6 scales were used as comparisons, namely the Barthel Index (BI), Repetitive Saliva Swallowing Test (RSST), Kubota Water Swallowing Test (KWST), Frenchay Dysarthria Assessment, Mini-Mental State Examination (MMSE), and the Montreal Cognitive Assessment (MoCA). Multiple regression analysis was performed to quantitate the relationship between the ICF scale and the other 7 scales. In addition, 60 ICF scales were analyzed by the least absolute shrinkage and selection operator (LASSO) method. A total of 21 ICF codes were identified, which were closely related with the other scales. These included 13 codes from Body Function, 1 from Body Structure, 3 from Activities and Participation, and 4 from Environmental Factors. A topographic network map with 30 ICF key codes was also generated to visualize their relationships. The number of ICF codes identified is in line with other well-established evaluation methods. The network topographic map generated here could be used as an instruction tool in future evaluations. We also found that attention functions and biting were critical codes of these scales, and could be used as treatment targets.

Abstract
The burden of stroke is increasing due to aging population and unhealthy lifestyle habits. The considerable rise in atrial fibrillation (AF) is due to greater diffusion of risk factors and screening programs. The link between AF and ischemic stroke is strong. The subtype most commonly associated with AF is cardioembolic stroke, which is particularly severe and shows the highest rates of mortality and permanent disability. A trend toward a higher prevalence of cardioembolic stroke in high-income countries is probably due to the greater diffusion of AF and the control of atherosclerotic of risk factors.

Abstract
Background After cardiac surgery with cardiopulmonary bypass (CPB), acquired coagulopathy often leads to post-CPB bleeding. Though multifactorial in origin, this coagulopathy is often aggravated by deficient fibrinogen levels. Objective To assess whether laboratory and thrombelastometric testing on CPB can predict plasma fibrinogen immediately after CPB weaning. Patients / Methods This prospective study in 110 patients undergoing major cardiovascular surgery at risk of post-CPB bleeding compares fibrinogen level (Clauss method) and function (fibrin-specific thrombelastometry) in order to study the predictability of their course early after termination of CPB. Linear regression analysis and receiver operating characteristics were used to determine correlations and predictive accuracy. Results Quantitative estimation of post-CPB Clauss fibrinogen from on-CPB fibrinogen was feasible with small bias (+0.19 g/l), but with poor precision and a percentage of error >30%. A clinically useful alternative approach was developed by using on-CPB A10 to predict a Clauss fibrinogen range of interest instead of a discrete level. An on-CPB A10 ≤10 mm identified patients with a post-CPB Clauss fibrinogen of ≤1.5 g/l with a sensitivity of 0.99 and a positive predictive value of 0.60; it also identified those without a post-CPB Clauss fibrinogen <2.0 g/l with a specificity of 0.83. Conclusions When measured on CPB prior to weaning, a FIBTEM A10 ≤10 mm is an early alert for post-CPB fibrinogen levels below or within the substitution range (1.5–2.0 g/l) recommended in case of post-CPB coagulopathic bleeding. This helps to minimize the delay to data-based hemostatic management after weaning from CPB.
