Haidegger M, Klock N, Kneihsl M, Fandler-Höfler S, Eppinger S, Eller K, Seiler S, Enzinger C, Gattringer T. Recurrent cerebrovascular events after recent small subcortical infarction. J Neurol 2024; 271:5055-5063. [PMID: 38802623 PMCID: PMC11319362 DOI: 10.1007/s00415-024-12460-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 05/13/2024] [Accepted: 05/17/2024] [Indexed: 05/29/2024]
Abstract
BACKGROUND Recent small subcortical infarcts (RSSI) are the neuroimaging hallmark feature of small vessel disease (SVD)-related acute lacunar stroke. Long-term data on recurrent cerebrovascular events including their aetiology after RSSI are scarce. PATIENTS AND METHODS This retrospective study included all consecutive ischaemic stroke patients with an MRI-confirmed RSSI (in the supply area of a small single brain artery) at University Hospital Graz between 2008 and 2013. We investigated associations between clinical and SVD features on MRI (STRIVE criteria) and recurrent cerebrovascular events, using multivariable Cox regression adjusted for age, sex, vascular risk factors and MRI parameters. RESULTS We analysed 332 consecutive patients (mean age 68 years, 36% women; median follow-up time 12 years). A recurrent ischaemic cerebrovascular event occurred in 70 patients (21.1%; 54 ischaemic strokes, 22 transient ischaemic attacks) and was mainly attributed to SVD (68%). 26 patients (7.8%) developed intracranial haemorrhage. In multivariable analysis, diabetes (HR 2.43, 95% CI 1.44-3.88), severe white matter hyperintensities (HR 1.97, 95% CI 1.14-3.41), and cerebral microbleeds (HR 1.89, 95% CI 1.32-3.14) on baseline MRI were related to recurrent ischaemic stroke/TIA, while presence of cerebral microbleeds increased the risk for intracranial haemorrhage (HR 3.25, 95% CI 1.39-7.59). A widely used SVD summary score indicated high risks of recurrent ischaemic (HR 1.22, 95% CI 1.01-1.49) and haemorrhagic cerebrovascular events (HR 1.57, 95% CI 1.11-2.22). CONCLUSION Patients with RSSI have a substantial risk for recurrent cerebrovascular events-particularly those with coexisting chronic SVD features. Recurrent events are mainly related to SVD again.

Abstract
BACKGROUND The activities of daily life (ADL) of stroke patients generally improves after rehabilitation. However, some patients remain at risk of ADL deterioration in the future. So far, there have been few studies on the factors related to ADL deterioration in stroke patients. OBJECTIVE To identify the factors related to ADL deterioration in stroke patients with independent mobility after discharge. METHODS We assessed 336 stroke patients with independent mobility who were discharged from the rehabilitation center between January 2016 and December 2018. The primary outcome was ADL deterioration, defined as that ADL assessed at 2 years after discharge decreased more than 15 points compared with that assessed at discharge. Univariate and multivariate statistical analyses were conducted to screen for factors related to ADL deterioration. RESULTS Overall, 62 (18.4%) patients exhibited ADL deterioration at 2 years after discharge.Age (OR = 1.114, 95%CI = 1.045-1.188, p = 0.001), vascular risk factors>3 (OR = 3.269, 95%CI = 1.189-8.986, p = 0.022) and with post-stroke depression (OR = 2.486, 95%CI = 1.011-6.114, p = 0.047) were risk factors for ADL deterioration in stroke patients. In contrast, elevated Berg Balance Scale (BBS) scores at discharge was a protective factor for ADL deterioration (OR = 0.484, 95%CI = 0.386-0.606, p < 0.001). CONCLUSIONS Nearly 1 in 5 stroke patients with independent mobility experienced ADL deterioration at 2 years after discharge. Aging, vascular risk factors>3, BBS at discharge, and post-stroke depression (PSD) were identified as factors associated with ADL deterioration.

Abstract
INTRODUCTION Type 2 diabetes mellitus (T2DM) is associated with various microvascular and macrovascular complications. Stroke, being a vascular complication, is associated with severe morbidity and mortality. Neutrophil lymphocyte ratio (NLR), a crude, inexpensive, and rather easily available modality to detect inflammation, has been utilized to find the extent of inflammation in type 2 diabetes mellitus patients. In this study, we find the effect of hemoglobin A1c (HbA1c) on NLR and the effect of NLR on stroke severity index. AIMS AND OBJECTIVES This study aims to determine the use of the NLR in predicting stroke severity in a type 2 diabetes mellitus patient. MATERIALS AND METHODS This study is an observational cross-sectional study. A total of 400 patients were enrolled, all of whom had type 2 diabetes mellitus, with 200 of them diagnosed with an ischemic stroke. The National Institute of Health stroke scale (NIHSS) was used to standardize stroke severity and NLR was calculated from differential counts. RESULTS The mean NLR for patients with type 2 diabetes mellitus was 3.87 ± 0.76 (mean ± SD), while for those with type 2 diabetes mellitus and stroke, it was 7.89 ± 1.29 (mean ± SD), with a statistically significant p-value < 0.001. Additionally, for every 1 unit increase in HbA1c, the NLR increased by 0.38 in type 2 diabetes mellitus patients and 0.86 in type 2 diabetes mellitus patients with stroke. Furthermore, each 1-unit increase in NLR corresponded to a rise of 0.80 in the stroke severity index. CONCLUSION The study shows a significant correlation between NLR in type 2 diabetes mellitus patients and stroke in type 2 diabetes mellitus patients. Also, it shows the significance of NLR in predicting stroke severity.

Abstract
Stroke remains one of the world's greatest causes of disability and death. Insulin resistance (IR) impairs insulin's beneficial effects on the brain and can change the course of illness in post-stroke patients. This review aims to find sufficient evidence to support the causal association of IR in ischemic stroke and with post-stroke prognosis (PSP). The review will also list probable mechanisms to better understand how IR affects stroke pathology. Various articles from PubMed Central, MEDLINE, and PubMed databases were reviewed, and then after careful consideration, 17 articles were selected. The studies, using various genetic and metabolic markers, have linked IR to increased incidence of ischemic stroke. Among the various types of strokes investigated from this standpoint, silent lacunar infarct stands out as a widely researched subtype. Even though the exact pathogenesis is still unclear, current evidence shows an interplay of atherosclerosis, embolism, and platelet dysfunction. The development of early neurological decline (END) in post-stroke patients has been used to link IR to poor PSP. It is also acknowledged to have contributed in some way to poor three-month outcomes. Modifying inflammatory pathways and developing glucotoxicity are some of the pathways by which IR affects PSP. After reviewing the studies, significant evidence was found to support the role of IR in causing ischemic stroke as well as in poor PSP. Additional investigation is required to assess its influence on three-month prognosis and its significance in various stroke subcategories.

Abstract
OBJECTIVE Cerebral small vessel disease (CSVD) is a common neurologic condition that contributes to considerable mortality and disability because of its impact on ischemic and hemorrhagic stroke risk and dementia. While attributes of the disease have been recognized for over two centuries, gaps in knowledge remain related to its prevention and management. The purpose of this review is to provide an overview of the current state of knowledge for CSVD. LATEST DEVELOPMENTS CSVD can be recognized by well-defined radiographic criteria, but the pathogenic mechanism behind the disease is unclear. Hypertension control remains the best-known strategy for stroke prevention in patients with CSVD, and recent guidelines provide a long-term blood pressure target of less than 130/80 mm Hg for patients with ischemic and hemorrhagic stroke, including those with stroke related to CSVD. Cerebral amyloid angiopathy is the second leading cause of intracerebral hemorrhage and may be increasingly recognized because of newer, more sensitive imaging modalities. Transient focal neurologic episodes is a relatively new term used to describe "amyloid spells." Guidance on distinguishing these events from seizures and transient ischemic attacks has been published. ESSENTIAL POINTS CSVD is prevalent and will likely be encountered by all neurologists in clinical practice. It is important for neurologists to be able to recognize CSVD, both radiographically and clinically, and to counsel patients on the prevention of disease progression. Blood pressure control is especially relevant, and strategies are needed to improve blood pressure control for primary and secondary stroke prevention in patients with CSVD.

Abstract
Ischemic and hemorrhagic strokes are the most common known cerebrovascular disease which can be induced by modifiable and non-modifiable risk factors. Age and race are the most common non-modifiable risk factors of stroke. However, hypertension, diabetes, obesity, dyslipidemia, physical inactivity, and cardiovascular disorders are major modifiable risk factors. Understanding the molecular mechanism mediating each of these risk factors is expected to contribute significantly to reducing the risk of stroke, preventing neural damage, enhancing rehabilitation, and designing suitable treatments. Abnormalities in the structure of the blood-brain barrier and blood vessels, thrombosis, vasoconstriction, atherosclerosis, reduced cerebral blood flow, neural oxidative stress, inflammation, and apoptosis, impaired synaptic transmission, excitotoxicity, altered expression/activities of many channels and signaling proteins are the most knows mechanisms responsible for stroke induction. However, the molecular role of risk factors in each of these mechanisms is not well understood and requires a lot of search and reading. This review was designed to provide the reader with a single source of information that discusses the current update of the prevalence, pathophysiology, and all possible molecular mechanisms underlying some major risk factors of stroke namely, hypertension, diabetes mellitus, dyslipidemia, and lipid fraction, and physical inactivity. This provides a full resource for understanding the molecular effect of each of these risk factors in stroke.

Abstract
The multidisciplinary approach to the rehabilitation of patients with stroke and diabetes has been followed in this article by a review of the literature published in the Web of Science in the last ten years. A review of the literature was performed using scientometric methods. VOS Viewer software was used to determine the research directions in this area. Scientometric analysis has extracted relevant published scientific output that treats diabetes and stroke. Studies based on qualitative research and the conclusions of these studies were analyzed. The clusters with the keywords used in the title and abstract by the authors who published in the Web of Science were reviewed and research directions in the field were formulated. The proper care of diabetes and its numerous consequences, including stroke and its neurologic complications, necessitates the fast identification of research findings in various types of medicines and their efficacy when applied to various patient groups, such as diabetic patients, whose recovery after a stroke is similar to that of a nondiabetic patient following hemodynamic stabilization, although it takes longer and has poorer outcomes. The limitations of the study refer to the fact that the data reviewed are from the Web of Science only.

Abstract
BACKGROUNDS AND OBJECTIVES The impact of metabolic syndrome (MetS)/hyperglycemia on the clinical outcomes of ischemic stroke treated with intravenous thrombolysis (IVT) remains controversial. This study aimed to determine the risks conferred by MetS and hyperglycemia to clinical outcomes in acute ischemic stroke patients treated with IVT. METHOD Three hundred forty-three ischemic stroke patients treated with IVT were prospective recruited and stratified into four groups: neither, MetS only, hyperglycemia only, or both. The primary outcome was the 3-month poor functional outcome (PFO) which was defined as a 3-month modified Rankin Score (mRS) score ≧3. The secondary outcome included the hemorrhagic transformation (HT) and symptomatic intracranial hemorrhage (sICH) after IVT. RESULTS MetS was recognized in 197 (57.43%) patients. During the first 24 h after IVT, 44 (12.83%) patients had HT, of which 17 had sICH. Three-month PFO was found in 98 (28.57%) patients. After adjustment for potential confounders, MetS (odds ratio (OR) = 3.140, 95% confidence interval (CI) = 1.724-5.718) was independently associated with PFO. However, neither MetS nor its components were associated with 24-h HT or sICH. In the further subgroup analysis, we used the "neither" group as reference and found that the presence of both MetS and hyperglycemia (OR = 3.192, 95% CI = 1.338-7.615) and the presence of hyperglycemia only (OR = 2.097, 95% CI = 1.052-4.179) were significantly related to the 3-month PFO. CONCLUSION MetS is an independent risk factor on 3-month PFO in acute ischemic stroke patients treated with IVT. Compared with "neither," hyperglycemia only or concurrent with MetS was associated with an elevated risk of PFO after receiving IVT.

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.

Impacts of treatments on recurrence and 28-year survival of ischemic stroke patients. Sci Rep 2021; 11:15258.

Abstract
Aspirin and nicametate are well-established therapies for preventing recurrence and mortality from stroke in patients diagnosed as ischemic stroke. However, their respective effects on the recurrence, making allowance for the duration of recurrence and death without the occurrence of recurrence, and long-term survival have not been well elucidated. We aimed to evaluate long-term effect of two kinds of treatment on cerebrovascular death among ischemic stroke patients with or without the recurrence of stroke. Data used in this study were derived from the cohort based on a multicenter randomized double-blind controlled trial during 1992 to 1995 with the enrollment of a total of 466 patients with first-time non-cardioembolic ischemic stroke who were randomly allocated to receive aspirin (n = 222) or nicametate (n = 244). The trial cohort was followed up over time to ascertain the date of recurrence within trial period and death until Sep of 2019. The time-dependent Cox regression model was used to estimate the long-term effects of two treatments on death from cerebrovascular disease with and without recurrence. A total of 49 patients experienced stroke recurrence and 89 cerebrovascular deaths was confirmed. Patients treated with nicametate were more likely, but non statistically significantly, to have recurrence (aHR: 1.73, 95% CI 0.96–3.13) as compared with those treated by aspirin. Nicametate reduced the risk of cerebrovascular death about 37% (aHR: 0.63, 95% CI 0.41–0.97) compared with aspirin. The aspirin group had a lower recurrence rate than the nicametate group even with recurrence after 1–2 years of follow-up of first stroke but the latter had significantly reduced death from cerebrovascular disease for nicametate group, which requires more research to verify.

Abstract
Metabolic syndrome (MetS) is a well-defined yet difficult-to-manage disease entity. Both the precipitous rise in its incidence due to contemporary lifestyles and the growing heterogeneity among affected populations present unprecedented challenges. Moreover, the predisposed risk for developing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in populations with MetS, and the viral impacts on host metabolic parameters, underscores the need to investigate this mechanism thoroughly. Recent investigations of metabolomics and proteomics have revealed not only differentially expressed substances in MetS, but also the consequences of diet consumption and physical activity on energy metabolism. These variations in metabolites, as well as protein products, also influence a wide spectrum of host characteristics, from cellular behavior to phenotype. Research on the dysregulation of gut microbiota and the resultant inflammatory status has also contributed to our understanding of the underlying pathogenic mechanisms. As for state-of-the-art therapies, advancing depictions of the bio-molecular landscape of MetS have emerged and now play a key role in individualized precision medicine. Fecal microbiota transplantation, aiming to restore the host's homeostasis, and targeting of the bile acid signaling pathway are two approaches to combatting MetS. Comprehensive molecular inquiries about MetS by omics measures are mandatory to facilitate the development of novel therapeutic modalities.

Abstract
Introduction Stroke recurrence accounts for a great percentage of catastrophic complications, yet no comprehensive study has analyzed the factors associated with stroke recurrence in Cameroon. We carried out this case-control study to better understand the factors associated with the stroke recurrence in Cameroon. Methods We collected sociodemographic, clinical, neuroimaging, laboratory, and therapeutic data of eligible patients who consulted the neurology and cardiology department of the Yaounde Central Hospital in Cameroon. We included all patients at least five years removed from their first stroke event who consulted the authors' institution as of January 15, 2019. Wilcoxon signed-rank and Fisher's exact tests were used. Also, a Cox regression model was used to identify confounders. Results We recruited 100 patients; seven out of ten patients had hypertension, while six out of 10 had a sedentary lifestyle. Half of the patients consumed alcohol regularly, while one patient out of five had diabetes. Most patients presented with their first stroke event, and a quarter had a stroke recurrence. Stroke recurrence was associated with right handedness (OR = 0.23, 95% CI = 0.16–0.33), congestive heart failure (OR = 3.45, 95% CI = 1.16–10.28), gout (OR = 4.34, 95% CI = 1.09–18.09), dysarthria (OR = 4.34, 95% CI = 1.30–14.54), and facial palsy (OR = 3.96, 95% CII = 1.49 – 10.51), as well as modifiable factors such as elevated abdominal circumference (P < 0.01), systolic blood pressure (P < 0.01), blood glucose level (PI <I 0.01), LDL cholesterol (P < 0.01), and triglyceride levels (P < 0.01). The mulitvariable regression model only identified laterality (B = –1.48, P = 0.04) as a statistically significant explanatory varibale for stroke recurrence. Conclusion We mapped the landscape of recurrent strokes in Cameroon. There is a need to evaluate the causes of suboptimal drug adherence rates and both the role and adherence to nonpharmacologic interventions.

Abstract
CONTEXT Lacunar strokes and diabetes are risk factors for cognitive dysfunction. Elucidating modifiable risk factors for cognitive dysfunction has great public health implications. One factor may be glycemic status, as measured by glycated hemoglobin (A1c). OBJECTIVE The aim of this study was to assess the relationship between A1c and cognitive function in lacunar stroke patients with diabetes. METHODS The effect of baseline and follow-up A1c on the baseline and the change in Cognitive Assessment Screening Instrument (CASI) score over time among participants with a median of 2 cognitive assessments (range, 1-5) was examined in 942 individuals with diabetes and a lacunar stroke who participated in the Secondary Prevention of Small Subcortical Strokes (SPS3) trial (ClinicalTrials.gov No. NCT00059306). RESULTS Every 1% higher baseline A1c was associated with a 0.06 lower standardized CASI z score (95% CI, -0.101 to -0.018). Higher baseline A1c values were associated with lower CASI z scores over time (P for interaction = .037). A 1% increase in A1c over time corresponded with a CASI score decrease of 0.021 (95% CI, -0.0043 to -0.038) during follow-up. All these remained statistically significant after adjustment for age, sex, education, race, depression, hypertension, hyperlipidemia, body mass index, cardiovascular disease, obstructive sleep apnea, diabetic retinopathy, nephropathy insulin use, and white-matter abnormalities. CONCLUSION This analysis of lacunar stroke patients with diabetes demonstrates a relationship between A1c and change in cognitive scores over time. Intervention studies are needed to delineate whether better glucose control could slow the rate of cognitive decline in this high-risk population.

Abstract
Objectives: This present study aimed to examine the effects of adiponectin-transfected endothelial progenitor cells (LV-APN-EPCs) on cerebral ischemia–reperfusion injury in rats with type 2 diabetes mellitus (T2DM) and to explore the underlying mechanisms. Methods: Seventy male Sprague–Dawley rats with T2DM were randomly divided into sham, phosphate-buffered saline (PBS), LV-APN-EPCs, LV-EPCs, and EPCs groups. Transient middle cerebral artery occlusion (MCAO) was induced by the intraluminal suture method. After 1 h of reperfusion, the five interventions were performed by tail-vein injections. The modified neurological severity score (mNSS) was used to assess neurological function before and on days 1, 7, and 14 after MCAO. After 14 days, magnetic resonance imaging scanning, hematoxylin and eosin staining, terminal dUTP nick-end labeling staining, Western blotting analysis, cluster of differentiation (CD) 31 immunofluorescence, and enzyme-linked immunosorbent assay were used to evaluate infarct rate, morphological damage, cell apoptosis, and microvessel density. Results: Compared with PBS, LV-EPCs, and EPCs groups, the LV-APN-EPCs group showed significantly lower mNSS score, lower infarct rate, and less morphological damage (all P < 0.05). In addition, compared with other groups, the LV-APN-EPCs group had significantly increased levels of B cell lymphoma/leukemia-2 (Bcl-2) protein, CD31+ microvessels, endothelial nitric oxide synthase, and vascular endothelial growth factor, and decreased levels of Bcl-2-associated X protein and neuronal apoptosis in the peri-infarct cortex (all P < 0.05). Conclusion: These results suggest that LV-APN-EPCs exert protective effects against cerebral ischemia–reperfusion injury in T2DM rats by increasing angiogenesis.

Abstract
BACKGROUND AND PURPOSE Delirium is a neuropsychiatric disorder of attention and awareness that develops over a short time and fluctuates in severity. Although delirium has been extensively studied in intensive care units, the incidence of delirium in stroke units and its predictors in stroke patients need further investigation. The endpoints of our study were incidence of delirium in acute stroke and the risk factors that predispose to this condition. METHODS Patients were consecutively enrolled in a stroke unit from April to October 2020. Inclusion criteria were: age ≥18 years, acute stroke and National Institute of Health Stroke Scale (NIHSS) score ≥1 at the time of clinical assessment of delirium. Exclusion criteria were: transient ischemic attack; absence of neuroimaging evidence of brain lesion; cerebral venous thrombosis; subarachnoid hemorrhage; and clinical conditions requiring intensive care unit treatment. All patients were evaluated by means of Richmond Agitation-Sedation Scale (RASS) and Confusion Assessment Method-Intensive Care Unit (CAM-ICU) scores at baseline, evaluations which were repeated within 72 h or when patients developed symptoms suggesting delirium. RESULTS The overall incidence of delirium was 36/120 (30%). Delirium was associated with aphasia (odds ratio [OR] 9.77; confidence interval [CI] 1.2-79.6), chronic obstructive pulmonary disease (COPD; OR 16.67; CI 1.1-263.0), deep Fazekas score (OR 5.05; CI 1.7-14.8), and physical restraint (OR 45.02; CI 1.4-1411.5). Diabetes was associated with a lower incidence of delirium (OR 0.04; CI 0.026-0.7). CONCLUSIONS Nearly one-third of patients (30%) had delirium in the acute phase of stroke. This finding supports the notion that delirium is a common complication of stroke. Delirium was associated with speech disorder, leukoencephalopathy, COPD and early use of physical restraint.

Abstract
Background and Purpose: Early age exposure to the Chinese Great Leap Forward famine (1959–1961) is associated with the incidence of risk factors for ischemic stroke. This study aims to examine the relationship between early age famine exposure and 12-month stroke recurrence. We sought to explore the interaction between famine exposure status and metabolic phenotypes on stroke recurrence and how the adherence of crucial evidence-based key performance indicators (KPI) would modify this interaction. Methods: We analyzed data of patients who were born between 1953 and 1964 in the China National Stroke Registry II (CNSR-II). The study population was further divided into five subgroups for comparing 12-month stroke recurrence. A multivariate Cox proportional hazard regression model was used in analyzing the impact of the concurrence of metabolic phenotypes—type 2 diabetes (T2D) or metabolic syndrome (MetS)—and early-age famine exposure on recurrent risk. The influence of the adherence to predefined KPI and concurrency of metabolic phenotype was also evaluated. Results: Concurrent T2D and early age famine exposure was associated with an increased recurrence risk of ischemic stroke with 12 months [adjusted hazard ratio (HR): 1.63, 95% confidence interval (CI) 1.28–2.07]. Optimal adherence to KPI was not associated with significantly reduced risk of 12-month stroke recurrence (adjusted HR: 0.80, 95% CI: 0.51–1.26). Conclusions: Concurrency of early-age famine exposure and diabetes mellitus was associated with a higher risk of stroke recurrence within 12 months, and adherence to evidence-based KPI did not reduce the risk significantly.

Abstract
Background This study aimed to investigate integrating radiomics with clinical factors in cranial computed tomography (CT) to predict ischemic strokes in patients with silent lacunar infarction (SLI). Methods Radiomic features were extracted from baseline cranial CT images of patients with SLI. A least absolute shrinkage and selection operator (LASSO)–Cox regression analysis was used to select significant prognostic factors based on ModelC with clinical factors, ModelR with radiomic features, and ModelCR with both factors. The Kaplan–Meier method was used to compare stroke-free survival probabilities. A nomogram and a calibration curve were used for further evaluation. Results Radiomic signature (p < 0.01), age (p = 0.09), dyslipidemia (p = 0.03), and multiple infarctions (p = 0.02) were independently associated with future ischemic strokes. ModelCR had the best accuracy with 6-, 12-, and 18-month areas under the curve of 0.84, 0.81, and 0.79 for the training cohort and 0.79, 0.88, and 0.75 for the validation cohort, respectively. Patients with a ModelCR score < 0.17 had higher probabilities of stroke-free survival. The prognostic nomogram and calibration curves of the training and validation cohorts showed acceptable discrimination and calibration capabilities (concordance index [95% confidence interval]: 0.7864 [0.70–0.86]; 0.7140 [0.59–0.83], respectively). Conclusions Radiomic analysis based on baseline CT images may provide a novel approach for predicting future ischemic strokes in patients with SLI. Older patients and those with dyslipidemia or multiple infarctions are at higher risk for ischemic stroke and require close monitoring and intensive intervention.

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
Stroke remains the second leading cause of death in the world, and its prevalence is projected to rise in the United States and globally. The main driver for increased stroke prevalence is aging of the population; however, best evidenced-based strategies for stroke treatment and prevention are not always followed for older patients. Furthermore, considerable gaps in knowledge exist for stroke prevention and treatment in elderly and very elderly patients. In this chapter, we discuss various aspects of stroke care in the elderly, including the evidence that guides stroke prevention and treatment. We focus on the challenges in managing stroke in the very elderly including the paucity of data to guide management. The sections span the continuum of stroke care, from primary prevention to management of stroke complications. Finally, we highlight the most significant unanswered questions regarding stroke care in the elderly.

Abstract
BACKGROUND The obesity paradox refers to the finding in observational studies that patients with obesity have a better prognosis after stroke than normal weight patients. AIM To test the hypothesis that there might be important heterogeneity within the obese stroke population, such that those with metabolic syndrome would be at higher risk for stroke or myocardial infarction and all-cause mortality compared to patients without metabolic syndrome. METHODS The Insulin Resistance Intervention after Stroke trial enrolled non-diabetic patients with a recent ischemic stroke or transient ischemic attack and insulin resistance. We examined the association between metabolic syndrome and outcome risk in patients with normal weight at entry (body mass index (BMI) = 18.5-24.9 kg/m2), overweight (BMI = 25-29.9 kg/m2), or obesity (BMI ≥ 30 kg/m2). Analyses were adjusted for demographic features, treatment assignment, smoking, and major comorbid conditions. RESULTS Metabolic syndrome was not associated with greater risk for stroke or myocardial infarction among 1536 patients who were overweight (adjusted hazard ratio (HR), 0.95; 95% confidence interval (CI): 0.69-1.31) or 1626 obese patients (adjusted HR, 1.00; 95% CI: 0.70-1.41). However, among 567 patients with a normal BMI, metabolic syndrome was associated with increased risk for stroke or myocardial infarction (adjusted HR, 2.05; 95% CI: 1.25-3.37), and all-cause mortality (adjusted HR, 1.70; 95% CI: 1.03-2.81) compared to patients without metabolic syndrome. CONCLUSIONS The presence of metabolic syndrome identified normal weight patients with insulin resistance but no diabetes who have a higher risk of adverse cardiovascular outcomes, compared with patients without metabolic syndrome.

Abstract
Cerebral small vessel disease (CSVD) is a broad category of cerebrovascular diseases which primarily affect the perforating arterioles, capillaries and venules with multiple distinct etiologies. In spite of distinctive pathogenesis, CSVD shares similar neuroimaging markers, including recent small subcortical infarct, lacune of presumed vascular origin, white matter hyperintensity of presumed vascular origin, perivascular space and cerebral microbleeds. The radiological features of neuroimaging markers are indicative for etiological analysis. Furthermore, in sporadic arteriosclerotic pathogenesis associated CSVD, the total CSVD burden is a significant predictor for stroke events, global cognitive impairment, psychiatric disorders and later life quality. This review aims to summarize the radiological characteristics as well as the clinical implication of CSVD markers and neuroimaging interpretation for CSVD symptomatology.

Abstract
Intracerebral hemorrhage (ICH) and lacunar infarction (LI) are the major acute clinical manifestations of cerebral small vessel diseases (cSVDs). Hypertensive small vessel disease, cerebral amyloid angiopathy, and hereditary causes, such as Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL), constitute the three common cSVD categories. Diagnosing the underlying vascular pathology in these patients is important because the risk and types of recurrent strokes show significant differences. Recent advances in our understanding of the cSVD-related radiological markers have improved our ability to stratify ICH risk in individual patients, which helps guide antithrombotic decisions. There are general good-practice measures for stroke prevention in patients with cSVD, such as optimal blood pressure and glycemic control, while individualized measures tailored for particular patients are often needed. Antithrombotic combinations and anticoagulants should be avoided in cSVD treatment, as they increase the risk of potentially fatal ICH without necessarily lowering LI risk in these patients. Even when indicated for a concurrent pathology, such as nonvalvular atrial fibrillation, nonpharmacological approaches should be considered in the presence of cSVD. More data are emerging regarding the presentation, clinical course, and diagnostic markers of hereditary cSVD, allowing accurate diagnosis, and therefore, guiding management of symptomatic patients. When suspicion for asymptomatic hereditary cSVD exists, the pros and cons of prescribing genetic testing should be discussed in detail in the absence of any curative treatment. Recent data regarding diagnosis, risk stratification, and specific preventive approaches for both sporadic and hereditary cSVDs are discussed in this review article.

Abstract
Objective This study aimed to investigate the association between the hemoglobin glycation index (HGI) and the prognosis of diabetic patients with ischemic stroke. Methods Data were derived from the Abnormal Glucose Regulation in Patients with Acute Stroke across China (ACROSS-China) registry. Diabetic patients with ischemic stroke were included. HGI was calculated by subtracting the predicted HbA1c based on fasting plasma glucose from the observed HbA1c, and then classified into three groups by the tertiles: low HGI (<-0.62), moderate HGI (-0.62 to 0.35) and high HGI (≥0.36). Outcomes included stroke recurrence, all-cause death and poor outcome at 12 months. Results A total of 976 diabetic patients were included. Low HGI was associated with an increased risk of stroke recurrence and poor outcome (adj.hazard ratio 1.53, 95% confidence intervals (CIs) 1.11-2.12, p = 0.01; and adj.odds ratio 1.64, 95% CI 1.13-2.38, p = 0.01, respectively), and high HGI was associated with an increased risk of poor outcome (adj.odds ratio 1.54, 95% CI 1.06-2.24, p = 0.02), compared with moderate HGI. We found a U-shaped association between HGI and the prognosis. Conclusion Both low HGI and high HGI was associated with an increased risk of poor prognosis in diabetic patients with ischemic stroke, compared with moderate HGI.

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.

Abstract
The present study evaluated the performance of three novel obese indicators, visceral adiposity index (VAI), lipid accumulation product (LAP) and waist circumference-triglyceride index (WTI), for identifying metabolic syndrome(MetS) in type 2 diabetes. A cross-sectional study was conducted on 711 type 2 diabetes in Qinhuangdao. The MetS was defined as the definition of Chinese Diabetes Society. Receiver operating characteristic curve analyses were performed to assess the accuracy of three obese indicators as diagnostic tests for MetS. The prevalence of MetS was 71.3%. In men, among all three obese indicators, the LAP had the highest area under curve (AUC) value (AUC = 0.894), followed by VAI (AUC = 0.860) and WTI (AUC = 0.855). In women, among all three obese indicators, the LAP had the highest AUC value (AUC = 0.906), followed by WTI (AUC = 0.887) and VAI (AUC = 0.881). However. there was no significant difference between the three obese indicators(P > 0.05). Three obese indicators were effective indicators for the screening of MetS, LAP and WTI are more simple.

Abstract
Cardiovascular disease including stroke is a major complication that tremendously increases the morbidity and mortality in patients with diabetes mellitus (DM). DM poses about four times higher risk for stroke. Cardiometabolic risk factors including obesity, hypertension, and dyslipidaemia often co-exist in patients with DM that add on to stroke risk. Because of the strong association between DM and other stroke risk factors, physicians and diabetologists managing patients should have thorough understanding of these risk factors and management. This review is an evidence-based approach to the epidemiological aspects, pathophysiology, diagnostic work up and management algorithms for patients with diabetes and stroke.

Abstract
BACKGROUND We aimed to determine the risk conferred by metabolic syndrome (METS) and diabetes mellitus (DM) to recurrent stroke in patients with minor ischemic stroke or transient ischemic attack from the CHANCE (Clopidogrel in High-risk patients with Acute Non-disabling Cerebrovascular Events) trial. METHODS AND RESULTS In total, 3044 patients were included. Patients were stratified into 4 groups: neither, METS only, DM only, or both. METS was defined using the Chinese Diabetes Society (CDS) and International Diabetes Foundation (IDF) definitions. The primary outcome was new stroke (including ischemic and hemorrhagic) at 90 days. A multivariable Cox regression model was used to assess the relationship of METS and DM status to the risk of recurrent stroke adjusted for potential covariates. Using the CDS criteria of METS, 53.2%, 17.2%, 19.8%, and 9.8% of patients were diagnosed as neither, METS only, DM only, and both, respectively. After 90 days of follow-up, there were 299 new strokes (293 ischemic, 6 hemorrhagic). Patients with DM only (16.1% versus 6.8%; adjusted hazard ratio 2.50, 95% CI 1.89-3.39) and both (17.1% versus 6.8%; adjusted hazard ratio 2.76, 95% CI 1.98-3.86) had significantly increased rates of recurrent stroke. No interaction effect of antiplatelet therapy by different METS or DM status for the risk of recurrent stroke (P=0.82 for interaction in the fully adjusted model of CDS) was observed. Using the METS (IDF) criteria demonstrated similar results. CONCLUSIONS Concurrent METS and DM was associated with an increased risk of recurrent stroke in patients with minor stroke and transient ischemic attack.

Abstract
Over the last several decades, the global incidence and prevalence of diabetes mellitus has increased significantly. The raised incidence rate is projected to continue as greater numbers of persons adopt a Western lifestyle and diet. Patients with diabetes mellitus are at heightened risk of both adverse microvascular and cardiovascular events. Moreover, once cardiovascular disease develops, diabetes mellitus exacerbates progression and worsens outcomes. The medical management of patients with diabetes mellitus mandates comprehensive risk factor modification and antiplatelet therapy. Recent clinical trials of new medical therapies continue to inform the care of patients with diabetes mellitus to reduce both cardiovascular morbidity and mortality.
