Abstract
Stroke is one of the leading causes of adult disability affecting millions of people worldwide. Post-stroke cognitive and motor impairments diminish quality of life and functional independence. There is an increased risk of having a second stroke and developing secondary conditions with long-term social and economic impacts. With increasing number of stroke incidents, shortage of medical professionals and limited budgets, health services are struggling to provide a care that can break the vicious cycle of stroke. Effective post-stroke recovery hinges on holistic, integrative and personalized care starting from improved diagnosis and treatment in clinics to continuous rehabilitation and support in the community. To improve stroke care pathways, there have been growing efforts in discovering biomarkers that can provide valuable insights into the neural, physiological and biomechanical consequences of stroke and how patients respond to new interventions. In this review paper, we aim to summarize recent biomarker discovery research focusing on three modalities (brain imaging, blood sampling and gait assessments), look at some established and forthcoming biomarkers, and discuss their usefulness and complementarity within the context of comprehensive stroke care. We also emphasize the importance of biomarker guided personalized interventions to enhance stroke treatment and post-stroke recovery.

Neuritin has a neuroprotective role in the rat model of acute ischemia stroke by inhibiting neuronal apoptosis and NLRP3 inflammasome. J Stroke Cerebrovasc Dis 2023; 32:107391. [PMID: 37832268 DOI: 10.1016/j.jstrokecerebrovasdis.2023.107391] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 09/22/2023] [Accepted: 09/24/2023] [Indexed: 10/15/2023] Open
Abstract
OBJECTIVES This study explored the anti-inflammatory, anti-neuronal apoptosis, and neuroprotective effects of Neuritin in rat models of acute ischemia stroke (AIS). METHODS AIS was induced in male Sprague Dawley rats by middle cerebral artery occlusion (MCAO). Rats were divided into sham, MCAO, MCAO+neuritin, MCAO + neuritin + PBS, MCAO + neuritin+MCC950, and MCAO + neuritin + MSU groups. Neurological score assessment, brain water content measurement, HE staining, TTC staining, TUNEL staining, ELISA, and Western blot were performed. RESULTS Neuritin significantly improved the neurobehavioral score, infarct size, brain water content, apoptosis, and neuroinflammatory response compared with the MCAO and MCAO + PBS groups within 24 h after AIS. Moreover, Neuritin inhibited the protein expression of NLRP3 inflammasome, and reduced the expression of IL-18 and IL-1B, thereby reducing the inflammatory response. Meanwhile, the neuroprotection, anti-inflammation, and anti-apoptosis effects of Neuritin were enhanced by MCC950 but partly counteracted by MSU. CONCLUSION Neuritin may reduce brain injury after AIS by inhibiting the expression of NLRP3 inflammasome and then inhibiting the inflammatory response.

Abstract
BACKGROUND Post-stroke cognitive impairment (PSCI) is a serious complication of stroke that warrants prompt detection and management. Consequently, the development of a diagnostic prediction model holds clinical significance. OBJECTIVE Machine learning algorithms were employed to identify crucial variables and forecast PSCI occurrence within 3-6 months following acute ischemic stroke (AIS). METHODS A prospective study was conducted on a developed cohort (331 patients) utilizing data from the Affiliated Zhongda Hospital of Southeast University between January 2022 and August 2022, as well as an external validation cohort (66 patients) from December 2022 to January 2023. The optimal model was determined by integrating nine machine learning classification models, and personalized risk assessment was facilitated by a Shapley Additive exPlanations (SHAP) interpretation. RESULTS Age, education, baseline National Institutes of Health Scale (NIHSS), Cerebral white matter degeneration (CWMD), Homocysteine (Hcy), and C-reactive protein (CRP) were identified as predictors of PSCI occurrence. Gaussian Naïve Bayes (GNB) model was determined to be the optimal model, surpassing other classifier models in the validation set (area under the curve [AUC]: 0.925, 95 % confidence interval [CI]: 0.861 - 0.988) and achieving the lowest Brier score. The GNB model performed well in the test sets (AUC: 0.919, accuracy: 0.864, sensitivity: 0.818, and specificity: 0.932). CONCLUSIONS The present study involved the development of a GNB model and its elucidation through employment of the SHAP method. These findings provide compelling evidence for preventing PSCI, which could serve as a guide for high-risk patients to undertake appropriate preventive measures.

Abstract
Given the expansion of life expectancy, the aging of the population, and the anticipated rise in the number of stroke survivors in Europe with severe neurological consequences in the coming decades, stroke is becoming the most prevalent cause of functional disability. Therefore, the prognosis for a stroke must be timely and precise. Two databases (MEDLINE and Scopus) were searched to identify all relevant studies published between 1 January 2005 and 31 December 2022 that investigated the relationship between thyroid hormone levels and acute stroke severity, mortality, and post-hospital prognosis. Only full-text English-language articles were included. This review includes Thirty articles that were traced and incorporated into the present review. Emerging data regarding the potential predictive value of thyroid hormone levels suggests there may be a correlation between low T3 syndrome, subclinical hypothyroidism, and poor stroke outcome, especially in certain age groups. These findings may prove useful for rehabilitation and therapy planning in clinical practice. Serum thyroid hormone concentration measurement is a non-invasive, relatively harmless, and secure screening test that may be useful for this purpose.

Abstract
Stroke is the second most common cause of cognitive impairment and dementia. Vascular dementia (VaD), a cognitive impairment following a stroke, is common and significantly impacts the quality of life. We recently demonstrated via gut microbe transplant studies that the gut microbe-dependent trimethylamine-N-oxide (TMAO) pathway impacts stroke severity, both infarct size and long-term cognitive outcomes. However, the molecular mechanisms that underly the role of the microbiome in VaD have not been explored in depth. To address this issue, we performed a comprehensive RNA-sequencing analysis to identify differentially expressed (DE) genes in the ischemic cerebral cortex of mouse brains at pre-stroke and post-stroke day 1 and day 3. A total of 4016, 3752 and 7861 DE genes were identified at pre-stroke and post-stroke day 1 and day 3, respectively. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis indicated pathways of neurodegeneration in multiple diseases, chemokine signaling, calcium signaling, and IL-17 signaling as the key enriched pathways. Inflammatory response genes interleukin-1 beta (Il-1β), chemokines (C-X-C motif chemokine ligand 10 (Cxcl10), chemokine ligand 2 (Ccl2)), and immune system genes (S100 calcium binding protein 8 (S100a8), lipocalin-2 (Lcn2)) were among the most significantly upregulated genes. Hypocretin neuropeptide precursor (Hcrt), a neuropeptide, and transcription factors such as neuronal PAS domain protein 4 (Npas4), GATA binding protein 3 (Gata3), and paired box 7 (Pax7) were among the most significantly downregulated genes. In conclusion, our results indicate that higher plasma TMAO levels induce differential mRNA expression profiles in the ischemic brain tissue in our pre-clinical stroke model, and the predicted pathways provide the molecular basis for regulating the TMAO-enhanced neuroinflammatory response in the brain.

Effects of NBP injection on the inflammatory response, oxidative stress response and vascular endothelial function in patients with ACI: A systematic review and meta-analysis. Medicine (Baltimore) 2023; 102:e33226. [PMID: 36897673 PMCID: PMC9997797 DOI: 10.1097/md.0000000000033226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Accepted: 02/16/2023] [Indexed: 03/11/2023] Open
Abstract
BACKGROUND Acute cerebral infarction (ACI) is a common medical emergency. This study is the first systematic review of the use of Dl-3-n-butylphthalide (NBP) injection in the treatment of ACI. The purpose of this study was to systematically evaluate the effects of NBP injection on the inflammatory response, oxidative stress response and vascular endothelial function in patients with acute ACI. The objective is to provide reference for clinical application. METHODS From the establishment of the database until August 2022, we systematically searched EMbase, PubMed, Cochrane Library, Web of Science, CNKI, VIP, and Wanfang Database. RCTs and retrospective studies were included in this study, and the results that qualified for inclusion were screened by 2 researchers and cross-checked. After the relevant data were extracted, a meta-analysis was performed using RevMan5.3 software. RESULTS A total of 3307 patients with ACI from 34 studies were analyzed. The meta-analysis showed that the C-reactive protein levels in the NBP combined group were effectively reduced compared with those in the control group (MD = -3.75, 95% confidence intervals [95% CI] [-4.95, -2.56], P < .00001). Based on comparison with the control group, it is evident that combination treatment with NBP is more effective than control group in reducing the oxidative stress response of ACI (MD[superoxide dismutase levels] = 22.16, 95% CI [14.20,30.11], P < .00001; MD[malondialdehyde levels] = -1.97, 95% CI [-2.62, -1.32], P < .00001). Comparison with the control group shows that combination treatment with NBP is more effective in improving vascular endothelial function in ACI patients (MD[vascular endothelial growth factor levels] = 71.44, 95% CI [41.22, 101.66], P < .00001; MD[endothelin-1 levels] = -11.47, 95% CI [-17.39, -5.55], P = .0001; MD[nitric oxide levels] = 9.54, 95% CI [8.39, 10.68], P < .00001) than control group. The NBP combined group also showed a greater reduction in cerebral infarct volume (CIV) and cerebral infarct size (CIS) of ACI (MD[CIV] = -1.52, 95% CI [-2.23, -0.81], P < .0001; MD[CIS] = -2.79, 95% CI [-3.65, -1.94], P < .00001). The NBP combined group did not show an increase in the incidence of adverse reactions compared with the control group (odds ratio = 1.06, 95% CI [0.73, 1.53], P = .77). CONCLUSION In summary, the use of NBP in combination with control group for ACI can reduce the degree of nerve damage, reduce inflammation and oxidative stress, improve vascular endothelial function, and reduce CIS and CIV in ACI patients, without increasing the incidence of clinical adverse events.

Abstract
Ischemic stroke is one of the major causes of death and long-term disability worldwide. C-reactive protein (CRP) as a potential biomarker for functional outcome after acute ischemic stroke remains controversial. The aim of the present study was to examine the association between the level of CRP and functional outcome of stroke. A total of 218 consecutive patients with acute ischemic stroke within 24 h after onset were recruited for the study. Poor functional outcome was defined as a modified Rankin scale score of >2 at 3 months after stroke. The retrospective analysis was performed to investigate whether CRP within 24 h after stroke is associated with poor functional outcome at 3 months. Multivariate logistic regression analysis indicated that the CRP level (odds ratio=1.146, 95%CI: 1.012-1.297, P=0.031) was an independent risk factor for poor outcome. The receiver operating characteristics curve analysis revealed that the optimal cut-off value of CRP to distinguish favorable from poor outcome was 6.34 (area under the curve=0.829, 95%CI: 0.772-0.887, P<0.001), with 68.2% sensitivity and 85.7% specificity. Spearman correlation analysis indicated that the CRP level was positively related to the baseline National Institutes of Health Stroke Scale (NIHSS) score (r=0.551, P<0.001), fasting glucose (r=0.301, P<0.001) and age (r=0.252, P<0.001). In conclusion, a high level of CRP within 24 h after onset was associated with a poor functional outcome after the acute ischemic event. The elevation of CRP may be correlated with the baseline NIHSS score, fasting glucose and age.

Abstract
BackgroundFluid-attenuated inversion recovery vascular hyperintensity (FVH) can reflect the collateral status, which may be a valuable indicator to predict the functional outcome of acute stroke (AS) patients.MethodsA total of 190 AS patients with large vessel occlusion (LVO) were retrospectively investigated. All patients completed a 6-month follow-up and their modified Rankin Scale (mRS) scores were recorded at 1, 3, and 6 months after intravenous thrombolysis (IVT). Based on their mRS at 3 months, patients were divided into two groups: poor prognosis (131 patients; 68.9% of all subjects) and favorable prognosis (59 patients; 31.1% of all subjects). The death records of 28 patients were also analyzed in the poor prognosis group.Results(1) Univariate and multivariate analyses showed that the higher National Institutes of Health Stroke Scale (NIHSS) score at admission, higher fasting blood glucose, and lower FVH score were independent risk factors to predict the poor prognosis of IVT. (2) Survival analysis indicated that FVH score was the only baseline factor to predict the 6-month survival after IVT. (3) Baseline FVH score had great prediction performance for the prognosis of IVT (area under the curve = 0.853). (4) Baseline FVH score were negatively correlated with the NIHSS score at discharge and mRS score at 1, 3, and 6 months.ConclusionAmong various baseline clinical factors, only the FVH score might have implications for 3-month outcome and 6-month survival of AS patients after IVT. Baseline FVH score showed great potential to predict the prognosis of the AS patients.

Abstract
Ischaemic stroke involves the rapid onset of focal neurological dysfunction, most commonly due to an arterial blockage in a specific region of the brain. Stroke is a leading cause of death and common cause of disability, with over 17 million people worldwide suffering from a stroke each year. It is now well-documented that neuroinflammation and immune mediators play a key role in acute and long-term neuronal tissue damage and healing, not only in the infarct core but also in distal regions. Importantly, in these distal regions, termed sites of secondary neurodegeneration (SND), spikes in neuroinflammation may be seen sometime after the initial stroke onset, but prior to the presence of the neuronal tissue damage within these regions. However, it is key to acknowledge that, despite the mounting information describing neuroinflammation following ischaemic stroke, the exact mechanisms whereby inflammatory cells and their mediators drive stroke-induced neuroinflammation are still not fully understood. As a result, current anti-inflammatory treatments have failed to show efficacy in clinical trials. In this review we discuss the complexities of post-stroke neuroinflammation, specifically how it affects neuronal tissue and post-stroke outcome acutely, chronically, and in sites of SND. We then discuss current and previously assessed anti-inflammatory therapies, with a particular focus on how failed anti-inflammatories may be repurposed to target SND-associated neuroinflammation.

Higher levels of C-reactive protein in the acute phase of stroke indicate an increased risk for post-stroke depression: A systematic review and meta-analysis. Neurosci Biobehav Rev 2021; 134:104309. [PMID: 34416242 DOI: 10.1016/j.neubiorev.2021.08.018] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Revised: 08/15/2021] [Accepted: 08/15/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Investigations have revealed the association between inflammation and post-stroke depression (PSD). However, whether the C-reactive protein (CRP) level, a biomarker of inflammation, would affect the development of PSD is still controversial. METHODS A systematic search of databases was performed for eligible studies. Standardized Mean Difference (SMD) with 95 % Confidence Interval (CI) was used to assess the association between the CRP level in the acute phase of stroke and the risk of PSD. RESULTS 13 cohort studies that involved 3536 participants were included. Combined results showed that compared with non-PSD patients, the CRP level of PSD patients was significantly higher on admission (SMD = 0.19, 95 % CI: 0.12-0.27). A subgroup analysis by classifying the assessment time of depression showed obvious differences of the CRP levels between the PSD patients who were diagnosed more than 1 month after stroke and the non-PSD (1-3 months: SMD = 0.16, 95 % CI: 0.06-0.25; >3months: SMD = 0.34, 95 % CI: 0.18-0.51). CONCLUSION A higher level of CRP in the acute phase of stroke suggests an increased risk for PSD.

Abstract
OBJECTIVES Pentraxin 3 (PTX3) may reflect local inflammatory status in tissues and thus serve as a potential biomarker of inflammation. Here, we investigated the utility of serum PTX3 as an index for assessing the 90-day prognosis of acute minor stroke patients. MATERIALS & METHODS Acute minor stroke patients (N = 241) and matched healthy control subjects (N = 241) were prospectively recruited. Clinical, laboratory, and imaging data were assessed. Blood samples were collected within 48h after acute minor stroke onset and serum PTX3 levels were determined. RESULTS Significant increases in stroke patients versus controls were obtained for serum PTX3 (3.14 ± 1.23 vs. 2.44 ± 0.74 ng/ml; p < .001) and C-reactive protein (CRP - 1.53 ± 0.38 vs. 1.35 ± 0.35 μg/ml; p < .05). Among the four stroke subtypes, as defined by modified Trial of Org 10172 in Acute Stroke Treatment classification, there were no statistically significant differences in serum PTX3 levels (p > .05). Multivariate logistic regression analysis revealed that serum PTX3 and LDL cholesterol could predict unfavorable outcomes at day 90 in Large Artery Atherosclerosis (LAA) patients. CONCLUSIONS Serum Pentraxin 3 may serve as an independent predictor for an unfavorable outcome in the LAA subtype of acute minor stroke and may possess a superior prognostic value as compared to CRP in this LAA subgroup.

Abstract
BACKGROUND The association between elevated C-reactive protein (CRP) level and poor functional outcome is conflicting in acute ischaemic stroke (AIS) patients. This meta-analysis sought to investigate the value of elevated CRP level in predicting poor functional outcome in AIS patients. MATERIAL AND METHODS A systematically literature search was performed in PubMed and Embase databases up to 31 October 2019. Prospective and retrospective studies evaluating the association between elevated CRP level and poor functional outcome (defined by the modified Rankin scale ≥3) beyond 3 months after AIS were included. RESULTS Ten studies with a total of 8087 AIS patients were identified in this meta-analysis. When compared with reference low CRP level, the highest CRP level was associated with an increased risk of poor functional outcome (multivariate-adjusted hazard ratio (HR) 1.99; 95% confidence interval (CI) 1.63-2.44) in a random effect model. Sensitivity analysis further confirmed the significance of CRP elevation for predicting poor functional outcome after AIS. CONCLUSIONS Elevated CRP level is significantly associated with poor functional outcome in patients with AIS. Baseline CRP level has potential to improve risk stratification of function outcome in AIS patients.

Abstract
Post-stroke cognitive impairment (PSCI), as one of the major complications after stroke, refers to a series of syndromes from mild cognitive impairment to dementia caused by stroke. Stroke has been reported to increase the risk of cognitive impairment by at least five to eight times. The assessment of PSCI usually relies on neuropsychological tests, but the results of these tests are subjective and inaccurate, and can be insufficient for the diagnosis and prognosis of PSCI. In recent years, an increasing number studies have indicated that changes in the expression of biomarkers such as C-reactive protein (CRP), interleukin 6 (IL-6) and IL-10 in blood, urine and other body fluids are associated with cognitive decline after stroke. Therefore, the detection of biomarkers in circulating blood serum, plasma and cerebrospinal fluid (CSF) may improve the accuracy of diagnosis and prognosis in PSCI. This review aims to summarize the studies on potential molecular biomarkers of PSCI.

Abstract
BACKGROUND The information on mortality after an acute stroke patient is still limited. OBJECTIVES The aim of this study was to investigate the prognostic potential of procalcitonin (PCT) serum levels in acute ischemic stroke. METHODS A total of 748 patients were enrolled in this study. Prognostic potential of PCT was evaluated by Kaplan-Meier analysis and multivariable Cox hazard regression analyses. RESULTS Procalcitonin levels were found to be significantly higher in acute ischemic stroke patients who died in 30 days than those who survived. Univariate logistic regression analysis showed that PCT was significantly associated with 30-day mortality, and Cox regression analysis revealed that PCT was a strong predictor of 30-day overall mortality. Kaplan-Meier analysis revealed that overall cumulative 30-day mortality was significantly higher in those with PCT levels >1.5 ng/mL when compared to those with PCT levels <1.5 ng/mL. CONCLUSIONS Procalcitonin is a significant independent prognostic marker of 30-day mortality after the one set of acute ischemic stroke.

Abstract
BACKGROUND Intravenous thrombolysis is the only approved pharmacological treatment for acute ischemic stroke (AIS) patients, but the immediate response to thrombolysis varies by patient. OBJECTIVE To investigate the factors associated with early neurological improvement (ENI) after the administration of intravenous recombinant tissue plasminogen activator (rt-PA) treatment to AIS patients within 4.5 hours of onset. METHODS Demographics, onset to treatment time, risk factors, and clinical and laboratory data of 209 AIS patients undergoing intravenous rt-PA therapy at a Chinese hospital between January 2013 and August 2016 were retrospectively analyzed. The National Institutes of Health Stroke Scale (NIHSS) score was recorded before thrombolytic therapy, 24 hours after the treatment, and 7 days after the treatment to evaluate the recovery of neurological function. ENI was defined as a ≥4-point decrease in NIHSS score compared with baseline or a score of 0 or 1 at 24 hours and 7 days. A multivariate logistic regression analysis was performed to assess the outcomes. RESULTS Of the 209 AIS patients treated by intravenous thrombolysis with rt-PA, low-density lipoprotein (LDL) levels were significantly lower (P<0.05) in patients with ENI. The multivariable analysis showed that non-atrial fibrillation (AF) was independently associated with ENI at 24 hours and 7 days after thrombolysis. An overall 40.3% non-AF patients had ENI 24 hours after thrombolysis (odds ratio=2.501, 95% confidence interval: 1.204-5.198; P=0.014), and 65.9% non-AF patients had ENI 7 days after thrombolysis (odds ratio=2.953, 95% confidence interval: 1.434-6.081; P=0.003). Onset to treatment time was an independent predictor (P<0.05) for ENI at 7 days after thrombolysis. The NIHSS score and diastolic blood pressure on admission were associated with symptomatic intracerebral hemorrhagic transformation. CONCLUSIONS Non-AF was independently associated with ENI after intravenous thrombolysis in AIS patients, but non-AF was not associated with the occurrence of symptomatic intracerebral hemorrhage. Onset to treatment time was an independent predictor of ENI at 7 days after thrombolysis in AIS patients.
