Contexte et objectif. La survie à long terme des accidents vasculaires cérébraux ischémiques (AVCI) reste un défi majeur. L'objectif de ce travail était d'analyser la mortalité à long terme des survivants d'AVCI. Méthodes. Il s'est agi d'une cohorte rétrospective portant sur les patients hospitalisés du 1er janvier 2017 au 31 décembre 2019, sortis vivants du service de neurologie au Centre Hospitalier Universitaire Sourô Sanou de Bobo-Dioulasso après un AVCI. Nous avons recouru aux méthodes de Kaplan Meier et la regression de Cox pour décrire respectivement la survie et les prédicteurs de la mortalité. Résultats. Au total, 87 patients dossiers ont été colligés. L'âge moyen était de 61,2 ans (±13,7). Le sex-ratio M/F était de 1,23/1. L'hypertension artérielle était le principal facteur de risque cardiovasculaire (65,5 %). Les antécédents de cardiopathies étaient présents chez 6 patients. La conscience était normale chez 82 patients et les complications de décubitus ont été observées chez 20 patients au cours de l'hospitalisation. La durée moyenne d'hospitalisation était de 15,8 jours. La mortalité cumulée en post hospitalisation était de 40,2 % à 4 ans. Les facteurs prédictifs de la mortalité étaient l'âge > 60 ans (p=0,008; HRa= 3,05 ; IC 95 % : 1,33-6,99), le score de Glasgow>9 (p<0,001; HRa = 0,09; IC 95 % : 0,02-0,31) et l'absence de complication de décubitus (p=0,009; HRa = 0,34; IC95 % : 0,15-0,76). Conclusion. Dans ce contexte, la mortalité à long terme des AVCI est élevée. Le renforcement du suivi vis-à-vis des groupes spécifiques pourrait contribuer à réduire considérablement cette mortalité à long terme.
Context and objective. Long-term survival from ischaemic stroke remains a major challenge. The aim of this study was to analyse the long-term mortality of stroke survivors at the Sourô Sanou University Hospital in Bobo-Dioulasso. Methods. This was a retrospective cohort of hospitalized patients from January 1, 2017 to December 31, 2019, discharged alive from the neurology service after ischaemic stroke. We used Kaplan Meier and Cox regression methods to describe survival and predictors of mortality, respectively. Results. A total of 87 patients were included in this study. The mean age was 61.2 years (±13.7). The sex ratio M/F was 1.23. Hypertension was the main cardiovascular risk factor (65.5%). A history of heart disease was present in 6 patients (6.9%). Consciousness was normal in 82 patients (94.2%) and decubitus complications were observed in 20 patients (23%) during hospitalisation. The average length of hospital stay was 15.8 days. Cumulative post-hospital mortality was 40.2% at 4 years. Factors predictive of mortality were age >60 years (p=0.008; aHR= 3.05; 95%CI: 1.33-6.99), Glasgow score>9 (p<0.001; aHR = 0.09; 95% CI: 0.02-0.31) and absence of decubitus complication (p=0.009; aHR = 0.34; 95%CI: 0.15-0.76). Conclusion. In this context, long-term mortality in ischaemic stroke is high. Closer monitoring of specific groups could help to reduce considerably this long-term mortality.

Background@#Among the multiple scoring systems for hemorrhagic transformation, only few of these address spontaneous hemorrhagic transformation after an ischemic stroke, with most done with Western population data. @*Objectives@#This study aims to identify the predictors for hemorrhagic transformation among patients with ischemic stroke admitted in a tertiary hospital in Cebu City, Philippines.@*Methods@#This is a retrospective cohort study of patients with ischemic stroke admitted in a tertiary hospital in Cebu City. Patients’ baseline characteristics, clinical, and radiologic data were collected. Chi square test and t-test were used to determine which variables were significantly different between patients with and without hemorrhagic transformation. Odds ratio (OR) and 95% confidence interval (CI) were determined to measure the association between the different variables and hemorrhagic transformation. @*Results@#A total of 500 ischemic stroke patients were included in the study. There were 28 (6%) ischemic stroke patients with Hemorrhagic Transformation. The mean age of these patients is 66.93 ± 12.42 years, 48.8% male, 10.8% had atrial fibrillation, and 2.4% had myocardial infarction. Controlling for the effect of confounders, white blood cell count (OR 1.11; 95% CI 1.03-1.19), myocardial infarction (OR 5.25; 95% CI 1.13-24.34), and presence of brain edema (OR 2.86; 95% CI 1.05-7.80) were significant predictors of hemorrhagic transformation.@*Conclusion@#White blood cell count, presence of brain edema, and myocardial infarction were significantly associated with hemorrhagic transformation among ischemic stroke patients.

Interactions between brain-resident and peripheral infiltrated immune cells are thought to contribute to neuroplasticity after cerebral ischemia. However, conventional bulk sequencing makes it challenging to depict this complex immune network. Using single-cell RNA sequencing, we mapped compositional and transcriptional features of peri-infarct immune cells. Microglia were the predominant cell type in the peri-infarct region, displaying a more diverse activation pattern than the typical pro- and anti-inflammatory state, with axon tract-associated microglia (ATMs) being associated with neuronal regeneration. Trajectory inference suggested that infiltrated monocyte-derived macrophages (MDMs) exhibited a gradual fate trajectory transition to activated MDMs. Inter-cellular crosstalk between MDMs and microglia orchestrated anti-inflammatory and repair-promoting microglia phenotypes and promoted post-stroke neurogenesis, with SOX2 and related Akt/CREB signaling as the underlying mechanisms. This description of the brain's immune landscape and its relationship with neurogenesis provides new insight into promoting neural repair by regulating neuroinflammatory responses.

Abstract The authors report the case of a 71-year-old woman presented to the Emergency Department with acute ischemic stroke. She was treated with rt-PA and interventional endovascular revascularization and developed rapidly progressing angioedema that led to emergency intubation. The standard treatment was not very effective and the swelling improved after infusion of fresh frozen plasma. Angioedema after rt-PA infusion could be a life-threatening emergency that requires quick airway management by skilled professionals. As this condition is triggered by several factors, such as unregulated histamine and bradykinin production, the traditional treatment recommended by the guidelines may not be sufficient and the use of FFP can be considered as a safe and valuable aid.

OBJECTIVE@#To establish a machine learning model to predict the risk of early neurological deterioration (END) based on the clinical and laboratory data of patients with acute ischemic stroke (AIS) before intravenous thrombolysis.@*METHODS@#The clinical data of AIS patients who received intravenous thrombolytic with recombinant tissue plasminogen activator (rt-PA) at the Stroke Center of the First Hospital of Qinhuangdao City from January 2019 to July 2022 were retrospectively analyzed. Patients were divided into END group and non-END group according to whether END appeared after intravenous thrombolytic. Clinical data of patients at admission were collected, including demographic characteristics, clinical evaluation, comorbidification, drug use history, laboratory tests, etc. Univariate and multivariate Logistic regression analysis were performed to screen out the independent predictors of the END of AIS patients after intravenous thrombolytic. The study subjects were randomly divided into a training set and a test set in a 7 : 3 ratio. Four machine learning prediction models, including Logistic regression (LR), K-nearest neighbor (KNN), support vector machine (SVM) and random forest (RF), were established based on independent predictors. The receiver operator characteristic curve (ROC curve) was used to evaluate the predictive ability of each model in END.@*RESULTS@#A total of 704 patients were enrolled, of whom 99 were identified as END and 605 as non-END. Univariate and multivariate Logistic regression analysis was used to screen out the National Institutes of Health stroke scale [NIHSS, odds ratio (OR) = 1.049, 95% confidence interval (95%CI) was 1.015-1.082, P = 0.004], systolic blood pressure (OR = 1.013, 95%CI was 1.004-1.022, P = 0.004), lymphocyte percentage (LYM%, OR = 0.903, 95%CI was 0.853-0.953, P < 0.001), platelet to lymphocyte ratio (PLR, OR = 1.007, 95%CI was 1.002-1.014, P = 0.013) were the independent predictors of END in AIS patients after intravenous thrombolysis. The area under the curve (AUC) of LR, KNN, SVM, and RF machine learning models in the test dataset were 0.789 (95%CI was 0.675-0.902), 0.797 (95%CI was 0.685-0.910), 0.851 (95%CI was 0.751-0.952) and 0.809 (95%CI was 0.699-0.919), respectively. The RF model had the highest sensitivity (95.7%). The accuracy (0.736), specificity (72.0%) and AUC of SVM model were the highest, and its overall prediction ability was better than the other three models.@*CONCLUSIONS@#Machine learning models have a potential role in early predicting the risk of END after intravenous thrombolysis in AIS patients, and can provide help in clinical decision-making for intravenous thrombolysis.

OBJECTIVE@#This study prospectively investigates the association between immunoglobulin G (IgG) N-glycan traits and ischemic stroke (IS) risk.@*METHODS@#A nested case-control study was conducted in the China suboptimal health cohort study, which recruited 4,313 individuals in 2013-2014. Cases were identified as patients diagnosed with IS, and controls were 1:1 matched by age and sex with cases. IgG N-glycans in baseline plasma samples were analyzed.@*RESULTS@#A total of 99 IS cases and 99 controls were included, and 24 directly measured glycan peaks (GPs) were separated from IgG N-glycans. In directly measured GPs, GP4, GP9, GP21, GP22, GP23, and GP24 were associated with the risk of IS in men after adjusting for age, waist and hip circumference, obesity, diabetes, hypertension, and dyslipidemia. Derived glycan traits representing decreased galactosylation and sialylation were associated with IS in men (FBG2S2/(FBG2 + FBG2S1 + FBG2S2): odds ratio ( OR) = 0.92, 95% confidence interval ( CI): 0.87-0.97; G1 n: OR = 0.74, 95% CI: 0.63-0.87; G0 n: OR = 1.12, 95% CI: 1.03-1.22). However, these associations were not found among women.@*CONCLUSION@#This study validated that altered IgG N-glycan traits were associated with incident IS in men, suggesting that sex discrepancies might exist in these associations.

Persistent neurogenesis exists in the subventricular zone (SVZ) of the ventricles and the subgranular zone (SGZ) of the dentate gyrus of the hippocampus in the adult mammalian brain. Adult endogenous neurogenesis not only plays an important role in the normal brain function, but also has important significance in the repair and treatment of brain injury or brain diseases. This article reviews the process of adult endogenous neurogenesis and its application in the repair of traumatic brain injury (TBI) or ischemic stroke, and discusses the strategies of activating adult endogenous neurogenesis to repair brain injury and its practical significance in promoting functional recovery after brain injury.

Electroacupuncture may play a role in treatment of learning and memory impairment after ischemic stroke by regulating phosphatidylinositol-3-kinase (PI3K)/protein kinase B (Akt) signaling pathway, cyclic adenosine monophosphate (cAMP)-dependent protein kinase A (PKA)/cAMP response element binding protein (CREB) signaling pathway, nerve growth factor (NGF)/tyrosine kinase-A (TrkA) signaling pathway, Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway, Notch signaling pathway, erythropoietin-producing hepatocyte (Eph)/ephrin signaling pathway. The interactions among these pathways should be further explored in treatment of learning and memory impairment after ischemic stroke.

The scientific basis of acupuncture on mesenchymal stem cells (MSCs) for treating ischemic stroke (IS) is discussed. MSCs transplantation has great potential for the treatment of tissue damage caused by early stage inflammatory cascade reactions of IS, but its actual transformation is limited by various factors. How to improve the homing efficiency of MSCs is the primary issue to enhance its efficacy. As such, the possible mechanisms of acupuncture and MSCs transplantation in inhibiting inflammatory cascade reactions induced by IS are explored by reviewing literature, and a hypothesis that acupuncture could promote the secretion of stromal cell-derived factor-1α (SDF-1α) from ischemic foci to regulate SDF-1α/CXC chemokine receptor 4 (CXCR4) axis, thereby improving the homing efficiency of MSCs transplantation, exerting its neuroprotective function, and improving the bed transformation ability, is proposed.

OBJECTIVE@#To observe the effects of acupuncture on neurologic function and serum inflammatory factors in patients after thrombolysis in acute ischemic stroke (AIS).@*METHODS@#A total of 102 AIS patients with onset to treatment time (OTT) ≤3 h were randomly divided into an observation group and a control group, 51 cases each group. In the control group, thrombolysis and conventional medical treatment were applied. On the basis of the treatment as the control group, acupuncture at Shuigou (GV 26), Zhongwan (CV 12), Qihai (CV 6), Neiguan (PC 6), etc. was applied in the observation group, 30 min each time, once a day. Both groups were treated for 2 weeks. Before and after treatment, the scores of National Institutes of Health stroke scale (NIHSS), modified Rankin scale (mRS), modified Barthel index (MBI) and serum level of homocysteine (Hcy), hypersensitive C-reactive protein (hs-CRP) were compared, and the clinical efficacy was evaluated in the two groups.@*RESULTS@#After treatment, the scores of NIHSS, mRS and serum level of Hcy, hs-CRP were decreased compared with those before treatment (P<0.05), while the MBI scores were increased (P<0.05) in the two groups. The scores of NIHSS, mRS and serum level of Hcy, hs-CRP in the observation group were lower than those in the control group (P<0.05, P<0.01), the MBI score in the observation group was higher than that in the control group (P<0.01). The total effective rate was 88.2% (45/51) in the observation group, which was superior to 70.6% (36/51) in the control group (P<0.05).@*CONCLUSION@#Acupuncture could promote the recovery of neurologic function in patients after thrombolysis in AIS, improve the ability of daily living, which may be related to reducing the level of inflammatory factors, thus inhibiting inflammatory response and improving cerebral ischemia reperfusion injury.

Background and Objective@#Stroke has remained one of the primary causes of significant morbidity and mortality. Among the therapeutic options for acute stroke management, endovascular thrombectomy is intended to remove the thrombi within the intracerebral vasculature and restore adequate perfusion to the surrounding penumbra. It is recommended up to 24 hours from onset of neurologic symptom. In the Philippines, only a few tertiary healthcare institutions are able to offer and perform endovascular thrombectomies. The aim was to describe the profile and discharge outcomes of endovascular thrombectomy for acute ischemic stroke at a tertiary hospital in our country. @*Methods@#We conducted a retrospective records review among 924 patients admitted for acute ischemic stroke from October 2018 to August 2021 who underwent mechanical thrombectomy. Clinical and functional outcomes were measured using the National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Score (mRS). @*Results@#Among 31 patients included in the study, 29 subjects (93.5%) had moderate to severe disability (mRS 3–5), and 25 (80.6%) had moderate stroke (NIHSS 6–21) on admission. The identified site of the cerebrovascular thrombi was within the M1 segment of the middle cerebral artery (41.9%, n=13). The stent retriever approach was performed in 19 participants (61.2%). Upon discharge, only 7 (22.6%) had favorable functional outcomes (MRS 0–2), and 9 (29.0%) resulted in mortality. Successful reperfusion was achieved in 92.3% of the patients.@*Conclusion@#Overall, endovascular thrombectomy is a possible treatment option for large vessel acute ischemic stroke in developing countries.

The therapeutic efficacy of Danshen and Jiangxiang in the treatment of ischemic stroke (IS) is relatively significant. Studying the mechanism of action of Danshen and Jiangxiang in the treatment of IS can effectively identify candidate traditional Chinese medicines (TCM) with efficacy. However, it is challenging to analyze the effector substances and explain the mechanism of action of Danshen-Jiangxiang from a systematic perspective using traditional pharmacological approaches. In this study, a systematic study was conducted based on the drug-target-symptom-disease association network using complex network theory. On the basis of the association information about Danshen, Jiangxiang and IS, the protein-protein interaction (PPI) network and the "drug pair-pharmacodynamic ingredient-target-IS" network were constructed. The different topological features of the networks were analyzed to identify the core pharmacodynamic ingredients including formononetin in Jiangxiang, cryptotanshinone and tanshinone IIA in Danshen as well as core target proteins such as prostaglandin G/H synthase 2, retinoic acid receptor RXR-alpha, sodium channel protein type 5 subunit alpha, prostaglandin G/H synthase 1 and beta-2 adrenergic receptor. Further, a method for screening IS candidates based on TCM symptoms was proposed to identify key TCM symptoms and syndromes using the "drug pair-TCM symptom-syndrome-IS" network. The results showed that three TCMs, namely Puhuang, Sanleng and Zelan, might be potential therapeutic candidates for IS, which provided a theoretical reference for the development of drugs for the treatment of IS.

Lixuwang~® Xuesaitong Soft Capsules(referred to as "Xuesaitong Soft Capsules") have the effects of promoting blood circulation, resolving blood stasis, and dredging meridians and collaterals. They are widely used in the prevention and treatment of cardiovascular and cerebrovascular diseases in clinical practice. Through years of clinical observation, they have shown significant efficacy in ischemic stroke, coronary heart disease, and other diseases, and have been recommended by multiple guidelines, consensus statements, and monographs. Based on the summary of clinical application experience by doctors and existing evidence-based research, following the Technical Specifications for Consensus Development of Chinese Patent Medicine by Clinical Experts issued by Standardization Office of the Chinese Association of Traditional Chinese Medicine, a nominal group method was used to reach 19 recommended opinions/consensus suggestions. This document proposes the timing of medication, syndrome differentiation for medication, therapeutic effects, dosage and administration, treatment duration, economic considerations, and safety considerations in the use of Xuesaitong Soft Capsules for the treatment of ischemic stroke and angina pectoris in coronary heart disease. It is intended for doctors in internal medicine, encephalopathy(neurology), cardiovascular medicine, geriatrics, emergency medicine, general practice, and traditional Chinese medicine departments of various medical institutions, as well as pharmacists in hospitals and pharmacies, as a medication reference when using Xuesaitong Soft Capsules. It is hoped that the widespread application of this consensus can improve the clinical efficacy of Xuesaitong Soft Capsules in the treatment of ischemic stroke and coronary heart disease, promote rational drug use, and reduce medication risks. This consensus has been reviewed and published by the China Association of Traditional Chinese Medicine, with the identification number GS/CACM 323-2023.

OBJECTIVES@#Restoration of blood circulation within "time window" is the principal treating goal for treating acute ischemic stroke. Previous studies revealed that delayed recanalization might cause serious ischemia/reperfusion injury. However, plenty of evidences showed delayed recanalization improved neurological outcomes in acute ischemic stroke. This study aims to explore the role of delayed recanalization on blood-brain barrier (BBB) in the penumbra (surrounding ischemic core) and neurological outcomes after middle cerebral artery occlusion (MCAO).@*METHODS@#Recanalization was performed on the 3rd day after MCAO. BBB disruption was tested by Western blotting, Evans blue dye, and immunofluorescence staining. Infarct volume and neurological outcomes were evaluated on the 7th day after MCAO. The expression of fibroblast growth factor 21 (FGF21), fibroblast growth factor receptor 1 (FGFR1), phosphatidylinositol-3-kinase (PI3K), and serine/threonine kinase (Akt) in the penumbra were observed by immunofluorescence staining and/or Western blotting.@*RESULTS@#The extraversion of Evans blue, IgG, and albumin increased surrounding ischemic core after MCAO, but significantly decreased after recanalization. The expression of Claudin-5, Occludin, and zona occludens 1 (ZO-1) decreased surrounding ischemic core after MCAO, but significantly increased after recanalization. Infarct volume reduced and neurological outcomes improved following recanalization (on the 7th day after MCAO). The expressions of Claudin-5, Occludin, and ZO-1 decreased surrounding ischemic core following MCAO, which were up-regulated corresponding to the increases of FGF21, p-FGFR1, PI3K, and p-Akt after recanalization. Intra-cerebroventricular injection of FGFR1 inhibitor SU5402 down-regulated the expression of PI3K, p-Akt, Occludin, Claudin-5, and ZO-1 in the penumbra, which weakened the beneficial effects of recanalization on neurological outcomes after MCAO.@*CONCLUSIONS@#Delayed recanalization on the 3rd day after MCAO increases endogenous FGF21 in the penumbra and activates FGFR1/PI3K/Akt pathway, which attenuates BBB disruption in the penumbra and improves neurobehavior in MCAO rats.

OBJECTIVE@#To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients.@*METHODS@#By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup.@*RESULTS@#Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens.@*CONCLUSIONS@#There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.
