Filler J, Georgakis MK, Dichgans M. Risk factors for cognitive impairment and dementia after stroke: a systematic review and meta-analysis. THE LANCET. HEALTHY LONGEVITY 2024; 5:e31-e44. [PMID: 38101426 DOI: 10.1016/s2666-7568(23)00217-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2023] [Revised: 10/16/2023] [Accepted: 10/17/2023] [Indexed: 12/17/2023] Open
Abstract
BACKGROUND Cognitive impairment and dementia are highly prevalent among stroke survivors and represent a major burden for patients, carers, and health-care systems. We studied the risk factors for post-stroke cognitive impairment (PSCI) and dementia (PSD) beyond the well established risk factors of age and stroke severity. METHODS In this systematic review and meta-analysis we conducted a systematic literature search from database inception until Sept 15, 2023. We selected prospective and retrospective cohort studies, post-hoc analyses from randomised controlled trials, and nested case-control studies of patients with acute stroke (ischaemic, haemorrhagic, and transient ischaemic attack), exploring associations between risk factors at baseline and PSCI or PSD over a follow-up period of at least 3 months. Study quality was assessed using the Newcastle-Ottawa quality assessment scale. We calculated pooled relative risks (RRs) with random-effects meta-analyses and performed subgroup, meta-regression, and sensitivity analyses. This study was preregistered with PROSPERO, CRD42020164959. FINDINGS We identified 162 eligible articles for our systematic review, of which 113 articles (89 studies, 160 783 patients) were eligible for meta-analysis. Baseline cognitive impairment was the strongest risk factor for PSCI (RR 2·00, 95% CI 1·66-2·40) and PSD (3·10, 2·77-3·47). We identified diabetes (1·29, 1·14-1·45), presence or history of atrial fibrillation (1·29, 1·04-1·60), presence of moderate or severe white matter hyperintensities (WMH; 1·51, 1·20-1·91), and WMH severity (1·30, 1·10-1·55, per SD increase) as treatable risk factors for PSCI, independent of age and stroke severity. For PSD, we identified diabetes (1·38, 1·10-1·72), presence of moderate or severe WMH (1·55, 1·01-2·38), and WMH severity (1·61, 1·20-2·14, per SD increase) as treatable risk factors. Additional risk factors included lower educational attainment, previous stroke, left hemisphere stroke, presence of three or more lacunes, brain atrophy, and low baseline functional status. Associations of risk factors with PSD were weaker in studies conducted and published more recently. We found substantial interstudy heterogeneity and evidence of reporting bias. INTERPRETATION Our results highlight the importance of cognitive impairment in the acute phase after stroke for long-term prediction of PSCI and PSD. Treatable risk factors include diabetes, atrial fibrillation, and markers of cerebral small vessel disease (ie, white matter hyperintensities and lacunes). Future trials should explore these risk factors as potential targets for prevention of PSCI and PSD. FUNDING German Research Foundation.

Abstract
Humanin (HN) is a 24-amino acid mitochondrial-derived polypeptide with cyto-protective and anti-apoptotic effects that regulates the mitochondrial functions under stress conditions. Accumulating evidence suggests the role of HN against age-related diseases, such as Alzheimer’s disease. The decline in insulin action is a metabolic feature of aging and thus, type 2 diabetes mellitus is considered an age-related disease, as well. It has been suggested that HN increases insulin sensitivity, improves the survival of pancreatic beta cells, and delays the onset of diabetes, actions that could be deployed in the treatment of diabetes. The aim of this review is to present the in vitro and in vivo studies that examined the role of HN in insulin resistance and diabetes and to discuss its newly emerging role as a therapeutic option against those conditions.

Front Cardiovasc Med 2022; 9:804410. [PMID: 35155629 PMCID: PMC8833232 DOI: 10.3389/fcvm.2022.804410] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Accepted: 01/04/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Although carotid sonographic features have been used as predictors of recurrent stroke, few large-scale studies have explored the use of machine learning analysis of carotid sonographic features for the prediction of recurrent stroke. METHODS We retrospectively collected electronic medical records of enrolled patients from the data warehouse of China Medical University Hospital, a tertiary medical center in central Taiwan, from January 2012 to November 2018. We included patients who underwent a documented carotid ultrasound within 30 days of experiencing an acute first stroke during the study period. We classified these participants into two groups: those with non-recurrent stroke (those who has not been diagnosed with acute stroke again during the study period) and those with recurrent stoke (those who has been diagnosed with acute stroke during the study period). A total of 1,235 carotid sonographic parameters were analyzed. Data on the patients' demographic characteristics and comorbidities were also collected. Python 3.7 was used as the programming language, and the scikit-learn toolkit was used to complete the derivation and verification of the machine learning methods. RESULTS In total, 2,411 patients were enrolled in this study, of whom 1,896 and 515 had non-recurrent and recurrent stroke, respectively. After extraction, 43 features of carotid sonography (36 carotid sonographic parameters and seven transcranial color Doppler sonographic parameter) were analyzed. For predicting recurrent stroke, CatBoost achieved the highest area under the curve (0.844, CIs 95% 0.824-0.868), followed by the Light Gradient Boosting Machine (0.832, CIs 95% 0.813-0.851), random forest (0.819, CIs 95% 0.802-0.846), support-vector machine (0.759, CIs 95% 0.739-0.781), logistic regression (0.781, CIs 95% 0.764-0.800), and decision tree (0.735, CIs 95% 0.717-0.755) models. CONCLUSION When using the CatBoost model, the top three features for predicting recurrent stroke were determined to be the use of anticoagulation medications, the use of NSAID medications, and the resistive index of the left subclavian artery. The CatBoost model demonstrated efficiency and achieved optimal performance in the predictive classification of non-recurrent and recurrent stroke.

Abstract
At present, the global incidence of diabetes has increased in countries with large populations, and the changes in developing regions are particularly worthy of attention. In the past 40 years or so, the income situation in China, India, and other countries has exploded, leading to changes in the way of life and work as well as an increase in the prevalence of diabetes. Metabolic disorders caused by diabetes can lead to secondary vascular complications, which have long-term malignant effects on the heart, kidneys, brain, and other vital organs of patients. Adequate primary prevention measures are needed to reduce the incidence of diabetic vascular complications, and more attention should be given to treatment after the disease. To this end, it is necessary to determine a standardized drug and physical therapy system and to build a more efficient and low-cost chronic disease management system.

Abstract
OBJECTIVE Because metabolic syndrome is a significant risk factor for cardio-cerebrovascular diseases and the relationship between metabolic syndrome (including its components) and the prognosis of stroke is controversial, this study was conducted to evaluate whether metabolic syndrome is associated with a high recurrence and mortality of stroke. METHODS This study was registered in the PROSPERO database (CRD42020177118). We searched for relevant observational cohort studies published from inception to April 23, 2020, using PubMed, Embase, and the Cochrane Library. Effect estimates with 95% confidence intervals (CIs) were pooled using the random-effects model. The primary and secondary outcomes were stroke recurrence and all-cause mortality, respectively. Leave-one-out sensitivity analyses and nonparametric trim-and-fill method were used to identify the stability of the results. RESULTS Thirteen cohort studies comprising 59,919 participants >60 years of age were included for analysis. Overall, metabolic syndrome was significantly associated with stroke recurrence (relative risk [RR] 1.46, 95% CI 1.07-1.97, p = 0.02). Among the metabolic syndrome components, low levels of high-density lipoprotein cholesterol (HDL-C) (RR 1.32, 95% CI 1.11-1.57, p = 0.002) and ≥2 metabolic syndrome components (RR 1.68, 95% CI 1.44-1.94, p < 0.001) significantly predicted stroke recurrence, whereas elevated triglycerides, elevated waist circumference, hyperglycemia, and hypertension failed to account for risk factors for stroke recurrence. Moreover, metabolic syndrome, not its components, was significantly associated with all-cause mortality (RR 1.27, 95% CI 1.18-1.36, p < 0.001). The stability of these results was further confirmed by the leave-one-out sensitivity analyses and nonparametric trim-and-fill method. CONCLUSIONS The present study indicates that metabolic syndrome and some of its components (low HDL-C and number of metabolic syndrome components) seem to be risk factors for stroke recurrence. Although metabolic syndrome is also associated with all-cause mortality, the role of its components in predicting all-cause mortality deserves further study.

Abstract
Background: Patients with metabolic syndrome (MetS) have a higher risk of developing cardiovascular diseases (CVD). However, controversy exists about the impact of MetS on the prognosis of patients with CVD. Methods: Pubmed, Cochrane library, and EMBASE databases were searched. Cohort Studies and randomized controlled trials post hoc analyses that evaluated the impact of MetS on prognosis in patients (≥18 years) with CVD were included. Relative risk (RR), hazard rate (HR) and 95% confidence intervals (CIs) were calculated for each individual study by random-effect model. Subgroup analysis and meta-regression analysis was performed to explore the heterogeneity. Results: 55 studies with 16,2450 patients were included. Compared to patients without MetS, the MetS was associated with higher all-cause death [RR, 1.220, 95% CI (1.103 to 1.349), P, 0.000], CV death [RR, 1.360, 95% CI (1.152 to 1.606), P, 0.000], Myocardial Infarction [RR, 1.460, 95% CI (1.242 to 1.716), P, 0.000], stroke [RR, 1.435, 95% CI (1.131 to 1.820), P, 0.000]. Lower high-density lipoproteins (40/50) significantly increased the risk of all-cause death and CV death. Elevated fasting plasma glucose (FPG) (>100 mg/dl) was associated with an increased risk of all-cause death, while a higher body mass index (BMI>25 kg/m2) was related to a reduced risk of all-cause death. Conclusions: MetS increased the risk of cardiovascular-related adverse events among patients with CVD. For MetS components, there was an increased risk in people with low HDL-C and FPG>100 mg/dl. Positive measures should be implemented timely for patients with CVD after the diagnosis of MetS, strengthen the prevention and treatment of hyperglycemia and hyperlipidemia.

Abstract
Background Considering that DNA methylation (DNAm) profiles are, in large part, modifiable by lifestyle and environmental influences, it has been proposed that epigenetic clocks provide a better estimate of biological age than chronological age, as associated with current health status. Even though metabolic diseases induce precocious aging, little is known about associations between metabolic syndrome (MetS) and DNA methylation clocks, and stochastic epigenetic mutations (SEMs), in a Korean population. Therefore, we assessed four different epigenetic clocks (Pan-tissue, Hannum, PhenoAge, and GrimAge), and their accelerations, on MetS and MetS-related lifestyle factors, in Koreans. We measured genome-wide DNA methylation (485,512 CpGs), using an Illumina 450 methylation BeadChip array, with data from 349 blood samples. Results DNAm GrimAge strongly correlated with chronological age (r = 0.77, p < 0.001) compared to the other three epigenetic clocks and SEMs. DNAm-based surrogate markers, with regard to MetS, including the gene encoding plasminogen activator inhibitor-1 (PAI1), also correlated with chronological age. Within cohorts stratified by age group, sex, regional area, smoking, and alcohol drinking, a positive correlation was observed between DNAm GrimAge and chronological age (0.43 ≤ r ≤ 0.78). In particular, we identified MetS to associate with accelerated GrimAge, and age-adjusted PAI1, in the middle-age group. Accerelated GrimAge also associated with risk of MetS in the middle-age group (odds ratio = 1.16, p = 0.046), which appears to mediate their associations with fasting glucose. Multiple linear regression showed that DNAm GrimAge, and its acceleration, associate with MetS scores, in the middle-age group (r = 0.26, p = 0.006). Age-adjusted PAI1 was also significantly different between the MetS and control groups, and further associated with MetS scores (r = 0.31, P < 0.001), in the middle age group. Conclusion DNAm GrimAge is a surrogate marker for MetS, and its component score, in Koreans. This association can be observed only in middle age. Therefore, appropriate DNA methylation clocks may aid in the prediction of Korean metabolic diseases.

A 5-year follow-up study. Top Stroke Rehabil 2020; 27:553-562. [PMID: 32172677 DOI: 10.1080/10749357.2020.1738661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/24/2022]
Abstract
Background/objectives: Functional disability (FD) is common after stroke and associated with the occurrence of future adverse events; however, whether FD is as strong a risk factor as comorbid vascular risk factors for cardiovascular events and death is unclear. Methods: Consecutive patients 3-6 months after index ischemic stroke were assessed at baseline and followed up for documented new cardiovascular events (recurrent stroke, acute myocardial infarction, and sudden death) and death within 5 years. Comorbidity of vascular risk factors was stratified as low or intermediate-to-high risk according to the Stroke Prognostic Instrument II. Four mutually exclusive cohorts were identified (1) intermediate-to-high risk only, n = 505, (2) FD only, n = 78, (3) both intermediate-to-high risk and FD, n = 264, and (4) low risk and no FD, n = 240. Results: The incidence of cardiovascular events was lowest in patients free of FD with low risk, followed by patients with FD alone, intermediate-to-high risk alone, and both. Compared with intermediate-to-high risk only, patients free of FD with low risk had a significantly lower adjusted hazard ratio (HR) (HR: 0.56, 95% confidence interval [CI]: 0.33-0.94), patients with FD only had a similar HR (HR: 0.47, 95% CI: 0.19 -1.18), and patients with both FD and intermediate-to-high risk had a significantly higher HR (HR: 2.13, 95% CI: 1.53-2.98) of cardiovascular events. A similar trend but a larger HR was noted for all-cause death. Conclusion: FD 3-6 months after ischemic stroke is a risk equivalent to comorbidity of conventional vascular risk factors for the incidence of cardiovascular events and mortality of all-cause death.

Abstract
BACKGROUND Intracranial atherosclerotic stenosis (ICAS) is a major cause of ischemic stroke, especially in Asia. Assessing relationships between novel risk factors and ICAS could lead strategies for improving outcomes. We aimed to evaluate the link between severity of metabolic syndrome (MetS) and extent of ICAS (≥ 50% stenosis). METHODS We conducted a cross-sectional study of consecutive Korean patients with acute ischemic stroke, admitted from March 2009 through May 2013, who underwent brain MRI/MRA. Patients were stratified into hypertension only, diabetes mellitus (DM), MetS only, MetS and hypertension, MetS and DM, and neither. MetS was defined using the harmonized criteria. RESULTS Of 1220 patients (mean age, 68.2 ± 12.7; female, 42.6%), 238 had hypertension only, 67 DM, 48 MetS only, 311 MetS and hypertension, 403 MetS and DM (88.3% having concomitant hypertension), and 153 neither. Patients with MetS and DM had higher prevalence of ICAS and more ICAS lesions vs. those with neither (all P < 0.001). Compared with neither condition (1.3 ± 0.8), extent of MetS component were greater by increasing MetS severity category (1.7 ± 0.5, 1.8 ± 0.4, 3.3 ± 0.5, 3.4 ± 0.6, and 3.9 ± 0.7, P < 0.001). Odds of ICAS (OR 3.40, 95% CI, 1.82-6.36), ICAS (≥ 2) (4.65, 2.15-10.05), and ICAS (≥ 3) (2.82, 1.02-7.82) remained independently higher in patients with MetS and DM. DM, MetS only, or MetS and hypertension trended towards higher ICAS lesions. CONCLUSION MetS and DM along with hypertension is associated with more extensive ICAS than MetS and hypertension or MetS only. Patients with MetS at high risk of hypertension and DM may benefit from therapeutic lifestyle changes to prevent stroke risk.

Abstract
Background: Mitochondrial dysfunction is implicated in the pathogenesis of Type 2 diabetes (T2D) and the development of diabetes related complications such as cardiovascular disease and stroke. Mitochondria produce several small polypeptides that may influence mitochondrial function and may impact on insulin sensitivity, such as humanin (HN) and the mitochondrial open reading frame of the 12S rRNA type-c (MOTS-c) that are mitochondrial derived proteins (MDP). The aim of this study was to determine MDP in normal, prediabetes and diabetes subjects. Subjects and Measurements: In this cross-sectional study, we analyzed the serum concentrations of MDP and adiponectin (ADP) in 225 subjects: normal (n = 68), pre-diabetes (n = 33), T2D less than (good control; n = 31), and greater than HbA1c 7% (poor control; n = 93) subjects. The relationship of serum MDP and ADP concentrations with biochemical and anthropometric measurements were performed and assessed by multilinear regression. Results: Serum HN concentrations were lower in T2D (p < 0.0001) and negatively correlated with age (p < 0.0001), HbA1c (p < 0.0001), glucose (p < 0.0001), triglycerides (p < 0.003), ALT (p < 0.004), and TG/HDL ratio (p < 0.001). Circulating HN levels were positively correlated to cholesterol (p < 0.017), LDL (p < 0.001), and HDL (p < 0.001). Linear regression analysis showed that HbA1c and ALT were two independent predictors of circulating HN. Similarly, serum MOTS-c was significantly lower in T2D subjects compared to controls (p < 0.007). Circulating MOTS-c positively correlated with BMI (p < 0.035), total cholesterol (p < 0.0001), and LDL (p < 0.001) and negatively correlated with age (p < 0.002), HbA1c (p < 0.001), and glucose (p < 0.002). Serum ADP concentrations were lower in T2D (p < 0.002) and negatively correlated with HbA1c (p < 0.001), weight (p < 0.032) TG (p < 0.0001), and ALT (p < 0.0001); and positively correlated with HDL (p < 0.0001) and HN (p < 0.003). Linear regression analysis showed that HbA1c and weight were two independent predictors of circulating ADP. Multilinear regression showed that HN and MOT-c correlated with each other, and only HN correlated with HbA1c. Conclusion: The MDPs HN and MOT-c, similar to ADP, are decreased in T2D and correlate with HbA1c. The data provide an additional evidence that mitochondrial dysfunction contributes to glycemic dysregulation and metabolic defects in T2D.

Ischemic stroke across sexes: What is the status quo? Front Neuroendocrinol 2018; 50:3-17.

Abstract
Stroke prevalence is expected to increase in the next decades due to the aging of the Western population. Ischemic stroke (IS) shows an age- and sex-dependent distribution in which men represent the most affected population within 65 years of age, being passed by post-menopausal women in older age groups. Furthermore, a sexual dimorphism concerning risk factors, presentation and treatment of IS has been widely recognized. In order to address these phenomena, a number of issue have been raised involving both socio-economical and biological factors. The latter can be either dependent on sex hormones or due to intrinsic factors. Although women have poorer outcomes and are more likely to die after a cerebrovascular event, they are still underrepresented in clinical trials and this is mirrored by the lack of sex-tailored therapies. A greater effort is needed in the future to ensure improved treatment and quality of life to both sexes.

Abstract
INTRODUCTION The prevalence of metabolic syndrome (MetS) and MetS-related stroke is set to increase dramatically in coming decades. MetS is a complex disease that includes endothelial dysfunction, insulin resistance, diabetes, hypertension, ectopic obesity, and dyslipidaemia and an increased risk of cardiovascular events. One function of high-density lipoprotein (HDL) cholesterol (HDL-C) is the cholesterol-efflux pathway, which is the pathway where cholesterol is removed from macrophages within the arterial walls back into the bloodstream and out to the liver. As one of the key functions of HDL, their hypothesis was that if they could measure HDL-C-efflux capacity, they would have a better handle on the role of HDL in atherosclerosis. However, there are no systematic analyses or well-conducted meta-analyses to evaluate the relationship between HDL-C functionality and MetS. The aim of this study is to examine this association of HDL-C functionality with MetS in different ages and sex. METHODS AND ANALYSIS The update systematic review and meta-analysis will be conducted using published studies that will be identified from electronic databases (i.e., PubMed, EMBASE, Web of Science, and Google Scholar). Studies that examined the association between HDL-C functionality and MetS; focused on cohort, case-control, and cross-sectional studies; were conducted among in adults aged 40 to 70 years; provided sufficient data for calculating odds ratio or relative risk with a 95% confidence interval; were published as original articles written in English or other languages; and have been published until January 2018 will be included. Study selection, data collection, quality assessment, and statistical syntheses will be conducted based on discussions among investigators. ETHICS AND DISSEMINATION Ethics approval was not required for this study because it was based on published studies. The results and findings of this study will be submitted and published in a scientific peer-reviewed journal. TRIAL REGISTRATION NUMBER PROSPERO (CRD42018083465).

Abstract
BACKGROUND Atherosclerosis is now widely recognized as a multifactorial disease with outcomes that arise from complex factors such as plaque components, blood flow, and inflammation. Epicardial adipose tissue (EAT) is a metabolically active fat depot, abundant in proinflammatory cytokines, and has been correlated with the extent and severity of carotid artery disease (CD). The locations most frequently affected by carotid atherosclerosis are the proximal internal carotid artery (ie, the origin) and the common carotid artery bifurcation. Progression of atheromatous plaque at the carotid bifurcation results in luminal narrowing, often accompanied by ulceration. However, there are no systematic analyses or well-conducted meta-analyses to evaluate the relationship between EAT and CD. The aim of this study is to examine this association of EAT with CD in different ages and sex. METHODS This systematic review and meta-analysis will be conducted using published studies that will be identified from electronic databases (ie, PubMed, EMBASE, Web of Science, and Google Scholar. Studies that (1) examined the association between EAT and CD, (2) focus on cohort, case-control and cross-sectional studies, (3) will conducted among in adults aged 40 to 70 years, (4) provided sufficient data for calculating ORs or relative risk with a 95% CI, (5) will published as original articles written in English or other languages, and (6) have been published until January 2018 will be included. Study selection, data collection, quality assessment and statistical syntheses will be conducted based on discussions among investigators. RESULTS We propose the current protocol to evaluate the evaluation of EAT with ED. CONCLUSION This systematic review will not need ethical approval, because it does not involve human beings. The results and findings of this study will be submitted and published in a scientific peer-reviewed journal. ETHICS AND DISSEMINATION Ethics approval was not required for this study because it was based on published studies. The results and findings of this study will be submitted and published in a scientific peer-reviewed journal. TRIAL REGISTRATION NUMBER PROSPERO (CRD42018083458).

[PMID: 29050848 DOI: 10.1016/j.jstrokecerebrovasdis.2017.03.014] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2016] [Revised: 02/22/2017] [Accepted: 03/12/2017] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND The association between metabolic syndrome (MetS) and recurrence of stroke remains unknown. We summarized the evidence by a meta-analysis of prospective cohort studies. METHODS We searched the PubMed, EMBASE, and Google Scholar databases from their inception until July 2016 for cohort studies investigating this research question; relevant information was extracted by 2 independent investigators, and then aggregated using the random-effects meta-analysis approach. RESULTS We identified 5 studies, including 7752 stroke patients who had a history of stroke or transient ischemic attack. Compared with persons without MetS, persons with MetS have a significantly higher risk of recurrent stroke, and the pooled relative risk (RR) was 1.52 (95% confidence interval (CI): 1.17-1.97). The strength of this association is greater than individual MetS components such as elevated blood pressure (RR = 1.05, 95% CI: .72-1.52), elevated triglycerides (RR = 1.04, 95% CI: .84-1.29), low high-density lipoprotein cholesterol (RR = 1.16, 95% CI: .91-1.48), or obesity (RR = 1.12, 95% CI: .89-1.41). The risk of recurrent stroke was highest in the group with elevated glycemia (RR = 1.70, 95% CI: 1.12-2.56). CONCLUSIONS This meta-analysis suggests that MetS might be an important predictor of recurrent stroke. Among the 5 components of MetS, elevated glycemia was a stronger predictor for recurrent stroke.

Sex differences in ischaemic stroke: potential cellular mechanisms. Clin Sci (Lond) 2017; 131:533-552.

Abstract
Stroke remains a leading cause of mortality and disability worldwide. More women than men have strokes each year, in part because women live longer. Women have poorer functional outcomes, are more likely to need nursing home care and have higher rates of recurrent stroke compared with men. Despite continued advancements in primary prevention, innovative acute therapies and ongoing developments in neurorehabilitation, stroke incidence and mortality continue to increase due to the aging of the U.S. POPULATION Sex chromosomes (XX compared with XY), sex hormones (oestrogen and androgen), epigenetic regulation and environmental factors all contribute to sex differences. Ischaemic sensitivity varies over the lifespan, with females having an "ischaemia resistant" phenotype that wanes after menopause, which has recently been modelled in the laboratory. Pharmacological therapies for acute ischaemic stroke are limited. The only pharmacological treatment for stroke approved by the Food and Drug Administration (FDA) is tissue plasminogen activator (tPA), which must be used within hours of stroke onset and has a number of contraindications. Pre-clinical studies have identified a number of potentially efficacious neuroprotective agents; however, nothing has been effectively translated into therapy in clinical practice. This may be due, in part, to the overwhelming use of young male rodents in pre-clinical research, as well as lack of sex-specific design and analysis in clinical trials. The review will summarize the current clinical evidence for sex differences in ischaemic stroke, and will discuss sex differences in the cellular mechanisms of acute ischaemic injury, highlighting cell death and immune/inflammatory pathways that may contribute to these clinical differences.

Abstract
Background Minor ischemic stroke (MIS) represents a major global public health problem worldwide due to high incidence. The aim of this study was to investigate whether metabolic syndrome (MetS) is a strong risk for MIS and subsequent vascular events (SVE). Methods A retrospective cohort study was performed examining symptomatic MIS in a Chinese neurologic outpatient population aged over 25 years without history of stroke. MetS was defined using the International Diabetes Federation criteria. MIS was diagnosed by magnetic resonance imaging-diffusion weighted images or fluid-attenuated inversion recovery. Results Of 1361 outpatients, a total of 753 (55.3%) patients were diagnosed with MIS; of them, 80% had a score of 0 using the MIS had a 0 score on the National Institutes of Health Stroke Scale. Among these, 303 (40.2%) individuals with MIS were diagnosed with MetS. Diagnosed of MIS with MetS significantly correlated with abdominal obesity (30.7% v.s 18.0%), hypertension (91.1% v.s 81.6%), increased blood glucose (6.9±2.4 v.s 5.0±0.4), dyslipidemia (78.2% v.s 48.2%), and SVE (50.5% v.s 11.3%) when compared with the controls group. On adjusted analysis, the risk of SVE was also significantly associated with three additional MetS criterion (RR,9.0; 95% CI, 5.677–14.46). Using Cox proportional analysis, risk of SVE in patient with MIS was significantly associated with MetS (RR, 3.3; 95% CI, 1.799–6.210), older age (RR, 1.0; 95% CI, 1.001–1.048), and high blood glucose (RR,1.1; 95%CI, 1.007–1.187). Conclusions The MetS is a strong risk factor for MIS, and patients presenting with MIS and MetS are at a high risk of SVE. Further studies are required to determine the improvement of Mets prevention in the reduction of MIS and SVE.
