Abstract
Acute cerebral infarction (ACI) includes atherosclerotic and cardiogenic ACI and involves a thrombotic state, requiring antithrombotic treatment. However, the thrombotic state in ACI cannot be evaluated using routine hemostatic examinations. Plasma soluble C-type lectin-like receptor 2 (sCLEC-2) and D-dimer levels were measured in patients with ACI. Plasma sCLEC-2 and D-dimer levels were significantly higher in patients with ACI than in those without it. The sCLEC-2 × D-dimer formula was significantly higher in patients with ACI than in those without it. A receiver operating characteristic curve showed a high sensitivity, area under the curve, and odds for diagnosing ACI in the sCLEC-2 × D-dimer formula. Although the sCLEC-2 and D-dimer levels were useful for the differential diagnosis between cardiogenic and atherosclerotic ACI, the sCLEC-2 × D-dimer formula was not useful. sCLEC2 and D-dimer levels are useful for the diagnosis of ACI and the sCLEC2 × D-dimer formula can enhance the diagnostic ability of ACI, and sCLEC2 and D-dimer levels may be useful for differentiating between atherosclerotic and cardioembolic ACI.

Antioxidant and Anti-Inflammatory Effects of Garlic in Ischemic Stroke: Proposal of a New Mechanism of Protection through Regulation of Neuroplasticity. Antioxidants (Basel) 2023; 12:2126.

Abstract
Stroke represents one of the main causes of death and disability in the world; despite this, pharmacological therapies against stroke remain insufficient. Ischemic stroke is the leading etiology of stroke. Different molecular mechanisms, such as excitotoxicity, oxidative stress, and inflammation, participate in cell death and tissue damage. At a preclinical level, different garlic compounds have been evaluated against these mechanisms. Additionally, there is evidence supporting the participation of garlic compounds in other mechanisms that contribute to brain tissue recovery, such as neuroplasticity. After ischemia, neuroplasticity is activated to recover cognitive and motor function. Some garlic-derived compounds and preparations have shown the ability to promote neuroplasticity under physiological conditions and, more importantly, in cerebral damage models. This work describes damage/repair mechanisms and the importance of garlic as a source of antioxidant and anti-inflammatory agents against damage. Moreover, we examine the less-explored neurotrophic properties of garlic, culminating in proposals and observations based on our review of the available information. The aim of the present study is to propose that garlic compounds and preparations could contribute to the treatment of ischemic stroke through their neurotrophic effects.

Independent external validation of a stroke recurrence score in patients with embolic stroke of undetermined source. Neurol Res Pract 2023; 5:51.

Abstract
BACKGROUND Embolic stroke of undetermined source (ESUS) accounts for a substantial proportion of ischaemic strokes. A stroke recurrence score has been shown to predict the risk of recurrent stroke in patients with ESUS based on a combination of clinical and imaging features. This study aimed to externally validate the performance of the ESUS recurrence score using data from a randomized controlled trial. METHODS The validation dataset consisted of eligible stroke patients with available magnetic resonance imaging (MRI) data enrolled in the PreDAFIS sub-study of the MonDAFIS study. The score was calculated using three variables: age (1 point per decade after 35 years), presence of white matter hyperintensities (2 points), and multiterritorial ischaemic stroke (3 points). Patients were assigned to risk groups as described in the original publication. The model was evaluated using standard discrimination and calibration methods. RESULTS Of the 1054 patients, 241 (22.9%) were classified as ESUS. Owing to insufficient MRI quality, three patients were excluded, leaving 238 patients (median age 65.5 years [IQR 20.75], 39% female) for analysis. Of these, 30 (13%) patients experienced recurrent ischaemic stroke or transient ischemic attack (TIA) during a follow-up period of 383 patient-years, corresponding to an incidence rate of 7.8 per 100 patient-years (95% CI 5.3-11.2). Patients with an ESUS recurrence score value of ≥ 7 had a 2.46 (hazard ratio (HR), 95% CI 1.02-5.93) times higher risk of stroke recurrence than patients with a score of 0-4. The cumulative probability of stroke recurrence in the low-(0-4), intermediate-(5-6), and high-risk group (≥ 7) was 9%, 13%, and 23%, respectively (log-rank test, χ2 = 4.2, p = 0.1). CONCLUSIONS This external validation of a published scoring system supports a threshold of ≥ 7 for identifying ESUS patients at high-risk of stroke recurrence. However, further adjustments may be required to improve the model's performance in independent cohorts. The use of risk scores may be helpful in guiding extended diagnostics and further trials on secondary prevention in patients with ESUS. TRIAL REGISTRATION Clinical Trials, NCT02204267.

Abstract
Recently, uncontrolled actin polymerization has been recognized as an initiator of early-onset blood-brain barrier (BBB) rupture. Here, using in vitro models, we found that after oxygen-glucose deprivation/reperfusion (OGD/R), endothelial overexpression of HSPB8 suppressed aberrant actin polymerization and thus preserved the integrity of BBB. We further investigated the mechanisms of HSPB8 in the control of actin assembly. HSPB8 suppressed the RhoA/ROCK2/p-MLC signaling pathway in bEnd.3 cells and the RhoA activator abrogated the inhibitory action of HSPB8 on actin reorganization after OGD/R. In addition, endothelial autophagic flux was impaired after OGD/R. This effect was attenuated by HSPB8 overexpression. Autophagy inhibition partially reversed the effect of HSPB8 on the RhoA/ROCK2/p-MLC pathway. Taken together, the present study revealed that the restoration of autophagic flux by overexpressing HSPB8, via the inhibition of the RhoA/ROCK2/p-MLC signaling pathway, reverses the aggregation of endothelial cytoskeleton actin, eventually alleviating OGD/R-induced BBB injury.

Abstract
Local ischemia in the cerebra leads to vascular injury and necrosis. Ferroptosis is involved in the pathophysiological process of many diseases and widely exists when ischemia-reperfusion injury occurs in many organs. The aim of this study was to evaluate the effect of Butylphthalide (NBP) on middle cerebral artery occlusion (MCAO) rats model-caused neuron injury. Sprague Dawley Rats were randomly allocated to receive sham and MCAO operation. NBP low-dose (40 mg/kg b.w), and high-dose (80 mg/kg b.w) were administrated in MACO rats. Results showed NBP improves infarct volume, attenuates neuronal apoptosis in the brain tissue of MCAO rats. The tumor necrosis factor (TNF-α), IL-6, and malondialdehyde (MDA) levels decreased after NBP administration, while the activity of superoxide dismutase (SOD) and the ratio of GSH/GSSG in MACO rats increased. MACO caused non-heme iron accumulation in the brain tissue and Perl's staining confirmed NBP attenuates ferroptosis in MACO rats. The protein expressions of SCL7A11 and glutathione peroxidase 4 (GPX4) decreased following MCAO, and NBP treatment subsequently increased the expression of SCL7A11 and GPX4. In vitro analysis in cortical neuron cells indicated that the GPX4 inhibitor reverses the inhibition of ferroptosis by NBP, which suggested that the SCL7A11/GPX4 pathway majorly contributed to the NBP ferroptosis protection effect.

Abstract
Introduction: Mortality estimates from sepsis and septic shock ranged from 18% to 35% and 40% to 60%, respectively, prior to 2014. Sepsis patients who experience subsequent cardiovascular events have increased mortality; however, data are limited among septic shock patients. This study reports in-hospital mortality, incident cardiovascular events, and cardiovascular procedures among sepsis patients with and without subsequent septic shock. Methods: Patients with a primary diagnosis of sepsis with and without a secondary diagnosis of septic shock were identified from the 2016 and 2017 National Readmissions Database. These patients were then evaluated for the occurrence of cardiovascular events and procedures. Results: A total of 2,127,137 patients were included in the study, with a mean age of 66 years. Twenty percent of patients (n = 420,135) developed subsequent septic shock. In-hospital mortality among patients with a primary diagnosis of sepsis was 5.3%, and it was 31.2% for those with subsequent septic shock. Notable cardiovascular events occurring among sepsis patients with and without subsequent septic shock, respectively, included: acute kidney injury (65.1% vs. 32.8%, P < .0001), acute systolic heart failure (9.8% vs. 5.1%, P < .0001), NSTEMI (8.8% vs. 3.2%, P < .0001), and ischemic stroke (2.3% vs. 0.9%, P < .0001). Similarly, the most common cardiovascular procedures between the two groups were: percutaneous coronary intervention (0.37% vs. 0.20%, P < .0001), intra-aortic balloon pump (0.19% vs. 0.02%, P < .0001), and extracorporeal membrane oxygenation (0.18% vs. 0.01%, P < .0001). Conclusions: Sepsis with subsequent septic shock is associated with an increased frequency of in-hospital cardiovascular events and procedures.

Abstract
Clinical value of anxiety and depression in acute ischemic stroke (AIS) is rarely studied. Thus, the aim of this study was to explore longitudinal changes of anxiety and depression, as well as their correlation with recurrence in AIS.A total of 120 AIS patients and 120 controls were enrolled in the study. Furthermore, comparison of the hospital anxiety and depression scale (HADS) score or rate between AIS and controls was determined by Mann-Whitney U test or Chi-square test. In AIS patients, change of HADS scores or linear trend of anxiety and depression rate over time were determined by Friedman test or Mantel-Haenszel Chi-square test. Moreover, correlation of anxiety and depression with the recurrence rate was analyzed by log-rank test.HADS for anxiety score, anxiety rate, HADS for depression score and depression rate were all elevated in AIS patients compared with controls (all P < .001). In AIS patients, HADS for anxiety score was elevated from discharged from hospital (M0) to month (M) 36 (P = .027), while anxiety rate was not (P = .107). Besides, HADS-D score and rate were both increased from M0 to M36 (both P < .001). Moreover, accumulating recurrence rate was 6.7%, 11.7%, and 17.5% at 1 year, 2 years, and 3 years, respectively. Additionally, anxiety at M24 (P = .033), depression at M0, M12, M24, and M36 (all P < .05) were all correlated with increased accumulating recurrence rate.Continuous monitoring of anxiety and depression might be beneficial for the management of AIS prognosis.

Abstract
Background: The genetic susceptibility to ischemic stroke (IS) is still not well-understood. Recent genome-wide association studies (GWASes) found that several single nucleotide polymorphisms (SNPs) in the Diacylglycerol acyltransferase 2 gene (DGAT2) and monoacylglycerol O-acyltransferase 2 (MOGAT2) cluster were associated with serum lipid levels. However, the association between the DGAT2-MOGAT2 SNPs and serum lipid phenotypes has not yet been verified in the Chinese people. Therefore, the present study was to determine the DGAT2-MOGAT2 SNPs and gene-environment interactions on serum lipid profiles and the risk of IS. Methods: Genotyping of 5 SNPs (DGAT2 rs11236530, DGAT2 rs3060, MOGAT2 rs600626, MOGAT2 rs609379, and MOGAT2 rs10899104) in 544 IS patients and 561 healthy controls was performed by the next-generation sequencing technologies. The association between genotypes and serum lipid data was determined by analysis of covariance, and a corrected P-value was adopted after Bonferroni correction. Unconditional logistic regression analysis was performed to assess the association between genotypes and the risk of IS after adjustment of potential confounders. Results: The rs11236530A allele was associated with increased risk of IS (CA/AA vs. CC, OR = 1.45, 95%CI = 1.12-1.88, P = 0.0044), whereas the rs600626G-rs609379A-rs10899104G haplotype was associated with decreased risk of IS (adjusted OR = 0.67, 95% CI = 0.48-0.93, P = 0.018). The rs11236530A allele carriers had lower high-density lipoprotein cholesterol (HDL-C) concentrations than the rs11236530A allele non-carriers (P < 0.001). The interactions of rs11236530-smoking, rs3060-smoking and rs10899104-smoking influenced serum apolipoprotein B levels, whereas the interactions of rs11236530- and rs3060-alcohol affected serum HDL-C levels (P I < 0.004-0.001). The interaction of rs600626G-rs609379A-rs10899104G-alcohol (OR = 0.41, 95% CI = 0.22-0.76) and rs600626G-rs609379C-rs10899104T-alcohol (OR = 0.12, 95% CI = 0.04-0.36) decreased the risk of IS (P I < 0.0001). Conclusions: The rs11236530A allele was associated with decreased serum HDL-C levels in controls and increased risk of IS in patient group. The rs600626G-rs609379A-rs10899104G haplotype, the rs600626G-rs 609379A-rs10899104G-alcohol and rs600626G-rs609379C-rs10899104T-alcohol interactions were associated with decreased risk of IS. The rs11236530 SNP may be a genetic marker for IS in our study populations.

Abstract
INTRODUCTION AND AIM Stroke is the leading cause of disability in adults and the second most common cause of death, at a rate of 11.8% worldwide. The purpose of this study was to examine the aetiological, demographic, and clinical characteristics of patients admitted to hospital because of acute strokes. MATERIALS AND METHODS This multicentre study retrieved information for all patients admitted to hospital because of an acute cerebrovascular event over a six-month period, and sociodemographic, aetiological, and clinical characteristics were recorded. RESULTS A total of 1136 patients, 520 of whom were women (45.7%), with a mean age of 70.3 ± 12.8 years, were included in the study. Of these, 967 were diagnosed with ischaemic stroke (IS) (85.1%), 99 with haemorrhagic stroke (HS) (8.7%), and 70 with transient ischaemic attack (6.1%). The most common risk factor for stroke was hypertension (73%). Carotid disease and hyperlipidaemia rates were higher in patients with HS. Numbers of functionally dependent patients with severe neurological status according to the National Institutes of Health Stroke Scale and modified Rankin scale were significantly higher in the HS group (P < .001). When IS was classified according to the Trial of Org 10172 in Acute Stroke Treatment, small vessel disease emerged as the most common cause (41%). The most common lesion localisations were the parietal lobe (23%) in the IS group and the thalamus (35.3%) in the HS group. Eighty-eight patients (7.7%), 62 (6.4%) in the ischaemic subgroup, and 26 (26.3%) in the haemorrhagic subgroup, died within the first month. CONCLUSION Current and accurate evaluations of stroke aetiology are essential for stroke prevention and treatment planning. This study, shows that no change occurred in the aetiology of stroke and epidemiological characteristics and that accurate identification of modifiable stroke risk factors is still a major goal.

Abstract
Background: Acute cerebral infarction (ACI) includes cardiogenic ACI treated with anticoagulants and atherosclerotic ACI treated with antiplatelet agents. The differential diagnosis between cardiogenic and atherosclerotic ACI is still difficult. Materials and Methods: The plasma sCLEC-2 and D-dimer levels were measured using the STACIA system. Results: The plasma sCLEC-2 level was significantly high in patients with ACI, especially those in patients with atherosclerotic or lacunar ACI, and plasma D-dimer levels were significantly high in patients with cardioembolic ACI. The plasma levels of sCLEC-2 and the sCLEC-2/D-dimer ratios in patients with atherosclerotic or lacunar ACI were significantly higher than those in patients with cardioembolic ACI. The plasma D-dimer levels in patients with atherosclerotic or lacunar ACI were significantly lower than those in patients with cardioembolic ACI. The plasma levels of sCLEC-2 and the sCLEC-2/D-dimer ratios were significantly higher in patients with atherosclerotic or lacunar ACI or acute myocardial infarction in comparison to patients with cardioembolic ACI or those with deep vein thrombosis. Conclusion: Using both the plasma sCLEC-2 and D-dimer levels may be useful for the diagnosis of ACI, and differentiating between atherosclerotic and cardioembolic ACI.

Abstract
To develop anti-ischemic stroke drugs with higher blood-brain barrier (BBB) penetrating capability and neuroprotective activity, a series of hybrid compounds containing edaravone analogue and 3-n-butylphthalide (NBP) ring-opened derivatives were synthesized and biologically evaluated. Among them, compound 10a displayed the highest protective activity in SH-SY5Y cells against oxygen and glucose deprivation (OGD) and H2O2 insults. Experiment results indicated that 10a could inhibit platelet aggregation via the synergistic action of the edaravone analogue and NBP, and its oral administration protected the rats against ischemia/reperfusion-induced brain injury. Moreover, 10a effectively inhibited apoptosis and reduced oxidative stress in OGD-exposed cells. Further analysis suggested that 10a might alleviate oxidative damage in SH-SY5Y cells via the modulation of the Nrf2 pathway. Collectively, these findings demonstrate that 10a can emerge as a potential candidate drug for the treatment of ischemic stroke.

"Case series: ischemic stroke associated with dehydration and arteriosclerosis in individuals with severe anorexia nervosa". J Eat Disord 2021; 9:39.

Abstract
BACKGROUND Numerous reports have indicated that patients with anorexia nervosa (AN) are at a relatively high risk of developing vascular diseases, including cardiovascular events and venous thromboembolism. However, there have been no previous reports of the development of ischemic stroke during refeeding therapy in patients with severe AN. This report is aimed at reporting the characteristics of an ischemic stroke in patients with AN. CASE PRESENTATIONS Our study included 29 admissions by independent 19 female patients cases (19 patients), who received thorough medical, neurological, and psychiatric examinations. Two patients were diagnosed as having developed ischemic stroke; the first patient showed multiple infarctions in the brain, while the second showed symptomatic focal infarction. Our findings suggest that dehydration and arteriosclerosis, in association with severe malnutrition, could predispose to the development of ischemic stroke in patients with severe AN. CONCLUSIONS Development of ischemic stroke in patients with AN might be overlooked. Watching out for neurological signs would help in early diagnosis of ischemic stroke in patients with AN during refeeding. Specific etiology could induce ischemic stroke in patients with AN even if they have no common risk factors of ischemia.

Abstract
Background: This comprehensive meta-analysis aimed to assess whether an increased homocysteine (Hcy) level is an independent predictor of unfavorable outcomes in acute ischemic stroke (AIS) patients. Methods: A comprehensive literature search was conducted up to August 1, 2020 to collect studies reporting Hcy levels in AIS patients. We analyzed all the data using Review Manager 5.3 software. Results: Seventeen studies with 15,636 AIS patients were selected for evaluation. A higher Hcy level was associated with a poorer survival outcome (OR 1.43, 95% CI: 1.25–1.63). Compared with the AIS group, Hcy levels were significantly lower in the healthy control patients, with an SMD of 5.11 and 95% CI (1.87–8.35). Analysis of the different subgroups of AIS demonstrated significant associations between high Hcy levels and survival outcomes only in Caucasian and Asian patients. Moreover, whereas high Hcy levels were closely associated with gender, B12 deficiency, smoking, and patients who received tissue plasminogen activator treatment, no significant difference was found between increased Hcy levels and age, drinking, hypertension, diabetes mellitus, and hyperlipidemia. In addition, the cut-off value (20.0 μmol/L) might be an optimum cut-off index for AIS patients in clinical practice. Conclusion: This meta-analysis reveals that the Hcy level may serve as an independent predictor for unfavorable survival outcomes in AIS patients, particularly in Caucasian and Asian AIS patients. Further studies can be conducted to clarify this relationship.

Abstract
Ischemic stroke is an urgent public health concern and one of the major causes of deaths and disabilities over the world. MicroRNA (miRNA) has become a key mediator of cerebral ischemia-reperfusion (I/R) injuries. However, whether miR-190 is involved in cerebral I/R-induced neuronal damage remains unknown. This study was to investigate the role of miR-190 in the brain I/R injury. We divided the rats into sham, I/R, control, and miR-190-mim (miR-190 mimics) groups. Quantitative real-time polymerase chain reaction (qRT-PCR), Nissl staining, flow cytometry, and western blot were conducted to examine the expression of miR-190 and cell apoptosis in different groups. The results showed that the expression of miR-190 was greatly decreased in rats suffering with I/R. Overexpression of miR-190 significantly reduced the increased neurological scores, brain water contents, infarct volumes, and neuronal apoptosis in rats suffering with I/R. In addition, we found that the expression of RhoA and Rho kinase was greatly elevated in rats suffering with I/R. Bioinformatics analysis indicated that Rho was a target of miR-190. Moreover, overexpression of miR-190 significantly downregulated the increased mRNA and protein expression of Rho/Rho kinase and cell apoptosis, while inhibition of miR-190 further upregulated the increased mRNA and protein expression of Rho/Rho kinase and cell apoptosis in rats suffering with I/R. Furthermore, knockdown of Rho significantly downregulated the increased mRNA and protein expression of Rho/Rho kinase and cell apoptosis, while these effects were inhibited by miR-190 inhibitors in rats suffering with I/R. These results indicate that miR-190 confers protection against brain I/R damage by modulating Rho/Rho-kinase signaling.
