Backgroud

Although both the atherogenic index of plasma (AIP) and high-sensitivity C-reactive protein (hs-CRP) are recognized as risk markers for stroke, their combined effect has yet to be fully understood. To address this gap, we introduced the inflammatory atherogenic index (IAI), a composite measure incorporating AIP and hs-CRP, and investigated its potential in predicting stroke ris

Methods

We analyzed data from the China Health and Retirement Longitudinal Study (CHARLS). IAI was calculated using the formula: IAI = AIP × hs-CRP / 10. Cox proportional hazard models were used to estimate stroke risk associated with IAI. Mediation analysis using VanderWeele’s method evaluated the mediating role of systolic and diastolic blood pressures.

Results

The study included 9,687 participants with a mean baseline age of 58.66 years (SD = 9.23), of whom 4,542 (46.9%) were male. Over the 7-year follow-up period, 662 incident stroke cases (6.8%) were recorded. After adjusting for all covariates, each standard deviation (SD) increase in the inflammatory atherogenic index (IAI) was linked to an 11.0% higher stroke risk (HR = 1.11, 95% CI: 1.03–1.19). A nonlinear, inverted U-shaped relationship between IAI and stroke risk was observed (P = 0.015). Mediation analysis showed that systolic and diastolic blood pressures mediated 19.64% and 25.79% of the IAI-stroke association. Hs-CRP and AIP also interacted synergistically to increase stroke risk (synergy index = 1.35, 95% CI: 1.03–1.76).

Conclusions

IAI is associated with increased stroke risk, with mediation by blood pressure. This highlights the potential of IAI as a biomarker for stroke risk, with early intervention in patients with high IAI potentially reducing stroke risk.
背景:虽然血浆动脉粥样硬化指数(AIP)和高敏c反应蛋白(hs-CRP)都被认为是卒中的危险标志物,但它们的联合作用尚未完全了解。为了解决这一差距,我们引入了炎症性动脉粥样硬化指数(IAI),这是一种结合AIP和hs-CRP的复合测量方法,并研究了其预测卒中风险的潜力。IAI计算公式为:IAI = AIP × hs-CRP / 10。Cox比例风险模型用于估计与IAI相关的卒中风险。采用VanderWeele方法进行中介分析,评估收缩压和舒张压的中介作用。结果:研究纳入9687名参与者,平均基线年龄58.66岁(SD = 9.23),其中4542名(46.9%)为男性。在7年的随访期间,记录了662例卒中(6.8%)。在对所有协变量进行调整后,炎症性动脉粥样硬化指数(IAI)的每一个标准差(SD)增加与卒中风险增加11.0%相关(HR = 1.11,95% CI: 1.03-1.19)。IAI与卒中风险呈非线性倒u型关系(P = 0.015)。中介分析显示收缩压和舒张压介导了19.64%和25.79%的iai -卒中关联。Hs-CRP和AIP也协同作用增加卒中风险(协同指数 = 1.35,95% CI: 1.03-1.76)。结论:IAI与卒中风险增加有关,血压起中介作用。这突出了IAI作为卒中风险生物标志物的潜力,对高IAI患者进行早期干预可能会降低卒中风险。

Introduction

Ischemic stroke and transient ischemic attack (TIA) reduce life expectancy in older adults. The impact of frailty on life expectancy following these events is unclear.

Methods

This nationwide retrospective cohort study used data from the Dutch health insurance claims database Vektis. We included patients aged ≥70 with ischemic stroke or TIA in 2018, selecting frail individuals using the U-PRIM frailty index. A non-frail control group was selected using frequency matching on age, sex, and socioeconomic status. Mortality data up to May 2024 provided 5.4–6.4 years of follow-up. Kaplan-Meier survival curves and Cox regression were used to estimate survival and calculate hazard ratios (HRs) for the association between frailty and mortality. As a secondary outcome, cardiovascular events were assessed.

Results

Among 16,778 frail and 10,069 non-frail patients, frailty was associated with higher mortality and shorter life expectancy. Mortality in frail vs. non-frail patients was 66 % vs. 55 % after ischemic stroke and 54 % vs. 36 % after TIA. Life expectancy was 3.8 vs. 5.2 years after ischemic stroke and 5.9 vs. >6.4 years after TIA. Adjusted HRs for the association of frailty with mortality were 1.30 after ischemic stroke and 1.72 after TIA. Cardiovascular events were more common in frail patients: 40 % vs. 38 % after ischemic stroke and 18 % vs. 13 % after TIA.

Conclusion

Frailty is associated with increased long-term mortality and reduced life expectancy after stroke or TIA. These findings may support treatment decisions and advanced care planning.
简介:缺血性中风和短暂性脑缺血发作(TIA)降低老年人的预期寿命。在这些事件之后,虚弱对预期寿命的影响尚不清楚。方法:这项全国性的回顾性队列研究使用了荷兰健康保险索赔数据库Vektis的数据。我们纳入了2018年年龄≥70岁的缺血性卒中或TIA患者,使用U-PRIM衰弱指数选择虚弱个体。采用年龄、性别和社会经济地位的频率匹配选择非体弱对照组。截至2024年5月的死亡率数据提供了5.4-6.4年的随访。Kaplan-Meier生存曲线和Cox回归用于估计生存率,并计算虚弱和死亡率之间关联的风险比(hr)。作为次要终点,心血管事件被评估。结果:在16778例体弱和10069例非体弱患者中,体弱与较高的死亡率和较短的预期寿命相关。体弱和非体弱患者在缺血性卒中后的死亡率分别为66%和55%,TIA后的死亡率分别为54%和36%。缺血性卒中后的预期寿命分别为3.8年和5.2年,TIA后的预期寿命分别为5.9年和6.4年。缺血性卒中后虚弱与死亡率相关的调整hr为1.30,TIA后为1.72。心血管事件在虚弱患者中更为常见:缺血性卒中后为40%对38%,TIA后为18%对13%。结论:虚弱与卒中或TIA后长期死亡率增加和预期寿命缩短有关。这些发现可能支持治疗决策和高级护理计划。

Background

Limited data exists on sex-specific differences in cancer subtypes, risk profiles, and mortality among patients with ischemic stroke.

Methods

This study analyzed 19,702 ischemic stroke patients (n = 12,241 men; n = 7,261 women) registered in the BioBank Japan database. We compared adjusted odds ratios (aOR) and 95 % confidence intervals (CI) for the prevalence of cancer across 14 common anatomical sites and sex-specific cancers between men and women. A multivariate logistic regression model was used to estimate aORs and 95 %CIs for traditional stroke risk factors associated with a cancer history by sex. Cox proportional hazards regression was used to estimate adjusted hazard ratios (aHR) and 95 %CIs for mortality based on cancer history by sex.

Results

Among the 19,702 individuals, 1,656 (8.4 %) had a history of cancer. Men showed significantly higher incidences of gastric (aOR 1.74[1.26-2.41]), bladder (aOR 3.49[1.73-3.03]), kidney (aOR 4.74[1.84-12.25]), and pharyngeal/laryngeal (aOR 6.65[2.17-20.39]) cancers compared to women. Conversely, sex-specific cancers (aOR 0.66[0.52-0.84]) were significantly less common in men than in women. In men, older age (aOR 1.80[1.67-1.94]), chronic kidney disease (aOR 1.73[1.23-2.44]), atrial fibrillation (aOR 1.38[1.07-1.77]), smoking (aOR 1.27[1.09-1.47]), and prior stroke (aOR 1.16[1.02-1.32]) were independently associated with a history of cancer. In women, older age (aOR 1.15[1.05-1.25]) was the only independent factor associated with a cancer history. During a median follow-up of 10 years, a history of cancer increased all-cause mortality risk in both men (aHR 1.27[1.16-1.39]) and women (aHR 1.32[1.14-1.48]).

Conclusion

Sex-specific differences in cancer subtypes and risk profiles were present among patients with ischemic stroke.
背景:关于缺血性脑卒中患者癌症亚型、风险概况和死亡率的性别特异性差异的数据有限。方法:本研究分析了在BioBank Japan数据库中登记的19,702例缺血性卒中患者(n=12,241名男性;n=7,261名女性)。我们比较了男性和女性在14个常见解剖部位和性别特异性癌症患病率的调整优势比(aOR)和95%置信区间(CI)。采用多变量logistic回归模型,按性别估算与癌症史相关的传统卒中危险因素的aORs和95% ci。Cox比例风险回归用于估计基于性别癌症病史的死亡率的校正风险比(aHR)和95% ci。结果:19702人中有1656人(8.4%)有癌症病史。男性胃癌(aOR为1.74[1.26-2.41])、膀胱癌(aOR为3.49[1.73-3.03])、肾癌(aOR为4.74[1.84-12.25])、咽喉癌(aOR为6.65[2.17-20.39])的发病率明显高于女性。相反,性别特异性癌症(aOR为0.66[0.52-0.84])在男性中的发病率明显低于女性。在男性中,年龄较大(aOR 1.80[1.67-1.94])、慢性肾脏疾病(aOR 1.73[1.23-2.44])、房颤(aOR 1.38[1.07-1.77])、吸烟(aOR 1.27[1.09-1.47])和既往卒中(aOR 1.16[1.02-1.32])与癌症史独立相关。在女性中,年龄较大(aOR为1.15[1.05-1.25])是与癌症病史相关的唯一独立因素。在中位随访10年期间,癌症病史增加了男性(aHR 1.27[1.16-1.39])和女性(aHR 1.32[1.14-1.48])的全因死亡风险。结论:缺血性脑卒中患者在癌症亚型和风险谱上存在性别特异性差异。

Background

Ischemic stroke is a leading cause of neurological disability. Current therapies fail to address its multifactorial pathologies. Miltirone, a bioactive compound from Salvia miltiorrhiza, has shown antioxidative and anti-inflammatory potential. However, its neuroprotective mechanisms in stroke remain unexplored.

Methods

Using young/aged dMCAO models and OGD/R-treated BV2 microglia, we evaluated Miltirone’s effects on infarct volume, neurological function, microglial polarization, lipid metabolism. Cerebral infarct volume was quantified by TTC staining. Neurological deficits were assessed via mNSS, rotarod, and adhesive removal tests. Cell viability was determined by CCK-8 assay. Pro-/anti-inflammatory cytokines, SOD activity and MDA content were measured by ELISA. Microglial polarization was analyzed via immunofluorescence and RT-qPCR. TLR4/MyD88/NF-κB pathway proteins and PLN2 were analyzed by Western blot. Lipid metabolism was evaluated by BODIPY staining. ROS was measured by flow cytometry

Results

Miltirone reduced cerebral infarct volume, attenuated brain edema, and improved neurological/motor recovery in dMCAO mice. It shifted microglial polarization toward the anti-inflammatory M2 phenotype by suppressing M1 markers and enhancing M2 markers. Miltirone downregulated pro-inflammatory cytokines while elevating anti-inflammatory cytokines. Miltirone restored lipid homeostasis by inhibiting lipid synthesis genes and activating lipolysis genes. This reduced lipid accumulation. Mechanistically, Miltirone suppressed LBP expression and TLR4/MyD88/NF-κB pathway. Moreover, Miltirone mitigated oxidative stress by lowering ROS, restoring SOD activity, and reducing lipid peroxidation.

Conclusion

Miltirone confers neuroprotection through multi-target actions. It simultaneously provides neuroinflammation, regulates lipid metabolism, and counters oxidative stress. This occurs via LBP/TLR4/NF-κB axis modulation. Its multitarget action addresses the complexity of ischemic stroke pathophysiology, positioning it as a promising therapeutic candidate for clinical translation.
背景:缺血性脑卒中是神经功能障碍的主要原因。目前的治疗方法无法解决其多因素病理。米替龙是一种来自丹参的生物活性化合物,具有抗氧化和抗炎作用。然而,其在中风中的神经保护机制尚不清楚。方法:采用年轻/老年dMCAO模型和OGD/ r处理BV2小胶质细胞,评价米替龙对梗死体积、神经功能、小胶质细胞极化、脂质代谢的影响。TTC染色定量脑梗死体积。通过mNSS、rotarod和黏合剂去除试验评估神经功能缺损。CCK-8法测定细胞活力。ELISA法测定抗炎因子、SOD活性和MDA含量。通过免疫荧光和RT-qPCR分析小胶质细胞极化。Western blot检测TLR4/MyD88/NF-κB通路蛋白和PLN2。BODIPY染色评价脂质代谢。结果:米替龙减少了dMCAO小鼠的脑梗死体积,减轻了脑水肿,改善了神经/运动恢复。它通过抑制M1标记和增强M2标记使小胶质细胞极化向抗炎M2表型转变。米替龙下调促炎细胞因子,同时升高抗炎细胞因子。米替龙通过抑制脂质合成基因和激活脂质分解基因来恢复脂质稳态。这减少了脂质积累。在机制上,米替龙抑制LBP表达和TLR4/MyD88/NF-κB通路。此外,米替龙通过降低ROS,恢复SOD活性和减少脂质过氧化来减轻氧化应激。结论:米替龙通过多靶点作用发挥神经保护作用。它同时提供神经炎症,调节脂质代谢,并对抗氧化应激。这是通过LBP/TLR4/NF-κB轴调节发生的。它的多靶点作用解决了缺血性卒中病理生理的复杂性,使其成为一种有前途的临床转化治疗候选药物。

Background

Carotid artery plaques, a hallmark of atherosclerosis, are key risk indicators for ischemic stroke, a major global health burden with 101 million cases and 6.65 million deaths in 2019. Early ultrasound detection is vital but hindered by manual analysis limitations. Machine learning (ML) offers a promising solution for automated plaque detection, yet its comparative performance is underexplored. This systematic review and meta-analysis evaluates ML models for carotid plaque detection using ultrasound.

Methods

We searched PubMed, Scopus, Embase, Web of Science, and ProQuest for studies on ML-based carotid plaque detection with ultrasound, following PRISMA guidelines. Eligible studies reported diagnostic metrics and used a reference standard. Data on study characteristics, ML models, and performance were extracted, with risk of bias assessed via PROBAST+AI. Pooled sensitivity, specificity, AUROC were calculated using STATA 18 with MIDAS and METADTA modules.

Results

Of ten studies, eight were meta-analyzed (200–19,751 patients) Best models showed a pooled sensitivity 0.94 (95% CI: 0.88–0.97), specificity 0.95 (95% CI: 0.86–0.98), AUROC 0.98 (95% CI: 0.97–0.99), and DOR 302 (95% CI: 54–1684), with high heterogeneity (I² = 90%) and no publication bias.

Conclusion

ML models show promise in carotid plaque detection, supporting potential clinical integration for stroke prevention, though high heterogeneity and potential bias highlight the need for standardized validation.
背景:颈动脉斑块是动脉粥样硬化的标志,是缺血性卒中的关键风险指标,缺血性卒中是全球主要的健康负担,2019年有1.01亿例病例和665万人死亡。早期超声检测是至关重要的,但受到人工分析限制的阻碍。机器学习(ML)为自动斑块检测提供了一个有前途的解决方案,但其比较性能尚未得到充分探索。本系统综述和荟萃分析评估了超声检测颈动脉斑块的ML模型。方法:我们按照PRISMA指南,检索PubMed、Scopus、Embase、Web of Science和ProQuest,查找基于ml的颈动脉斑块超声检测的研究。符合条件的研究报告了诊断指标并使用了参考标准。提取有关研究特征、ML模型和性能的数据,并通过PROBAST+AI评估偏倚风险。使用STATA 18结合MIDAS和METADTA模块计算合并敏感性、特异性和AUROC。结果:10项研究中,8项进行了荟萃分析(200-19,751例患者)。最佳模型的总敏感性为0.94 (95% CI: 0.88-0.97),特异性为0.95 (95% CI: 0.86-0.98), AUROC为0.98 (95% CI: 0.97-0.99), DOR为302 (95% CI: 54-1684),异质性高(I² = 90%),无发表偏倚。结论:ML模型在颈动脉斑块检测中显示出希望,支持潜在的卒中预防临床整合,尽管高度异质性和潜在的偏倚突出了标准化验证的必要性。

Background

Premature atherosclerosis has been observed among people with HIV (PWH) with high risk of cerebrovascular disease. The aim of this study was to evaluate premature atherosclerosis in young PWH with and without ischemic stroke.

Methods

We conducted a prospective case-control study at the University Teaching Hospital in Lusaka, Zambia between March 2022 and October 2024, comparing young PWH with non-cardioembolic ischemic stroke (cases) with PWH without a history of stroke (controls) matched (1:2) for age, sex and race. Premature atherosclerosis was assessed using a Mindray DC-40, linear probe 8-13 MHz high resolution B-mode ultrasound to measure carotid intima-media thickness (cIMT; abnormal≥0.70 mm) and pulse wave velocity (PWV; abnormal≥10.00m/s).

Results

We analyzed results for 50 cases and 100 controls. Compared to controls, cases were more likely to have traditional stroke risk factors such as hypertension (42 % vs. 1 %, p=0.001); shorter duration from HIV diagnosis (<3 months: 16 % vs. 1 %, p=0.001);and markers of atherosclerotic disease, including higher PWV [10.89 (9.99-12.15) m/s vs. 8.97 (8.16 - 9.54) m/s, p<0.001] and increased cIMT [0.79 (0.70-0.99) mm vs. 0.63 (0.58 - 0.67) mm, p<0.001]. Poor WHO HIV clinical stage (stage 3: aOR 58, 95 % CI 1-3213, p=0.04), higher PWV (aOR 8.7, 95 % CI 2.0-38.1, p=0.004) and urban residence (aOR 25.5, 95 % CI 1.6-413.4, p=0.02) were independently associated with ischemic stroke in multivariable analyses.

Conclusion

In this cohort of young-onset HIV-associated non-cardioembolic ischemic stroke, premature atherosclerosis, as indicated by higher PWV, was independently associated with stroke.
背景:早发动脉粥样硬化已在高危的HIV感染者(PWH)中被观察到。本研究的目的是评估年轻PWH伴和不伴缺血性中风的过早动脉粥样硬化。方法:我们于2022年3月至2024年10月在赞比亚卢萨卡大学教学医院进行了一项前瞻性病例对照研究,比较年轻PWH与无卒中史的PWH(对照组)在年龄、性别和种族上匹配(1:2)的非心脏栓塞性缺血性卒中(病例)。采用迈瑞DC-40,线性探头8-13MHz高分辨率b型超声测量颈动脉内膜-中膜厚度(cIMT,异常≥0.70mm)和脉搏波速度(PWV,异常≥10.00m/s)评估过早动脉粥样硬化。结果:我们分析了50例病例和100例对照的结果。与对照组相比,病例更有可能有传统的卒中危险因素,如高血压(42%比1%,p=0.001);结论:在这个年轻发病的HIV相关非心源性缺血性卒中队列中,高PWV所表明的过早动脉粥样硬化与卒中独立相关。

Background

Stroke is the second leading cause of death globally and the third leading cause of disability, severely impacting quality of life and increasing healthcare costs. Identifying underlying causes is critical for effective management. Oral health is closely linked to stroke occurrence, and tooth loss is a common oral health issue. However, few studies have explored the relationship between the number of missing teeth and stroke. This study aimed to elucidate the association between the number of missing teeth and stroke.

Methods

This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES). The number of missing teeth was assessed by professional dentists. To examine the relationship between tooth loss and stroke risk, multivariable logistic regression analysis and restricted cubic splines (RCS) were employed. Subgroup analyses were further conducted to verify the consistency of findings across populations.

Results

The study enrolled 23,473 adult participants, of whom 4.19 % had a history of stroke. Participants diagnosed with stroke exhibited a higher number of missing teeth compared to those without stroke. In a model adjusted for multiple variables, each additional missing tooth was associated with a 2 % increased likelihood of stroke (OR = 1.02, 95 % CI: 1.01, 1.03). Participants with total tooth loss had a 163 % higher incidence of stroke compared to those with no missing teeth (OR = 2.63, 95 % CI: 1.90, 3.62). The RCS curve revealed a significant nonlinear positive correlation between the number of missing teeth and stroke risk.

Conclusions

A significant positive association between the number of missing teeth and stroke was observed among U.S. adults. Further large-scale, rigorously controlled studies are warranted to validate the reliability and generalizability of these findings.
中风是全球第二大死亡原因和第三大残疾原因,严重影响生活质量并增加医疗保健费用。识别潜在的原因对于有效的管理至关重要。口腔健康与中风的发生密切相关,牙齿脱落是常见的口腔健康问题。然而,很少有研究探讨缺牙数量和中风之间的关系。本研究旨在阐明缺牙数量与中风之间的关系。方法本横断面研究利用了国家健康和营养检查调查(NHANES)的数据。缺牙的数量由专业牙医评估。为了研究牙齿脱落与卒中风险之间的关系,采用多变量logistic回归分析和限制三次样条(RCS)。进一步进行亚组分析,以验证不同人群研究结果的一致性。结果该研究纳入了23,473名成人参与者,其中4.19%有中风史。与没有中风的人相比,被诊断为中风的参与者显示出更多的牙齿缺失。在对多个变量进行调整的模型中,每增加一颗缺牙,卒中的可能性增加2% (OR = 1.02, 95% CI: 1.01, 1.03)。与没有牙齿缺失的参与者相比,全牙缺失的参与者中风发生率高163% (OR = 2.63, 95% CI: 1.90, 3.62)。RCS曲线显示缺牙数与卒中风险呈显著的非线性正相关。结论在美国成年人中,缺牙数量与中风呈显著正相关。进一步的大规模、严格控制的研究是有必要的,以验证这些发现的可靠性和普遍性。

Background

A large number of studies have previously established a causal association between stroke and dementia, and have demonstrated a strong correlation between ischemic or hemorrhagic stroke and all-cause dementia, respectively. Given the overall increasing prevalence of all-cause dementia worldwide and the absence of data from randomized clinical trials confirming the existence of effective dementia interventions.The aim of this paper is to apply the GBD database to estimate the proportion and trends of dementia following ischemic and hemorrhagic strokes globally and within regions, and to discuss potential risk factors for vascular dementia using Mendelian randomization (MR).

METHODS

Using a literature review and Bayesian regression analysis, we estimated the relative risk of dementia following ischemic and hemorrhagic stroke. The proportion of dementia attributable to cerebral infarction and cerebral hemorrhage (PAF) and the burden of dementia under specific clinical etiology-year-sex-region were then calculated in conjunction with the Global Burden of Disease Study (GBD) burden of disease data. And projections were made for the next 10 years. Using the GWAS database, data on vascular dementia and 17 risk factors were collected, and causality was determined by two-sample MR analysis. In addition, potential mediators of risk factor effects on vascular dementia were searched from 338 cerebrospinal fluid metabolites by two-step MR.

RESULTS

The relative risk of dementia following cerebral hemorrhage ( relative risk(RR):3.02[1.17-7.78],P<0.001 ) was higher than that of cerebral infarction (RR: 2.07[1.47-2.96], P<0.001). However, due to the high prevalence of cerebral infarction, the PAF for dementia due to cerebral infarction was higher than that of cerebral hemorrhage. Together, they explain 1.31% (1.41%-1.21%) of global dementia. The burden of dementia following both cerebral infarction and cerebral hemorrhage showed significant spatial and temporal heterogeneity. Four causal associations were replicated in two-sample MR and a mediating role for cerebrospinal fluid(CSF) metabolites X-11261 was identified by 2-step MR.

INTERPRETATION

one point three one percent of dementia prevalence globally could be explained by ischemic stroke and hemorrhagic stroke.Quantifying the proportion of dementia caused by these two conditions has helped us to gain a comprehensive understanding of the causes of dementia.Through two-sample MR study and two-step MR analysis, modifiable risk factors and cerebrospinal fluid mediators associated with vascular dementia were identified, elucidating intervention methods for preventing or delaying the typical characteristics of dementia. This is crucial for future efforts in disease prevention and treatment.
大量的研究已经建立了中风和痴呆之间的因果关系,并分别证明了缺血性或出血性中风和全因痴呆之间有很强的相关性。鉴于全球范围内全因痴呆的总体患病率不断上升,且缺乏随机临床试验数据证实存在有效的痴呆干预措施。本文的目的是应用GBD数据库估计全球和区域内缺血性和出血性中风后痴呆的比例和趋势,并使用孟德尔随机化(MR)讨论血管性痴呆的潜在危险因素。方法通过文献回顾和贝叶斯回归分析,我们估计缺血性和出血性卒中后痴呆的相对风险。然后结合全球疾病负担研究(GBD)疾病负担数据,计算脑梗死和脑出血(PAF)导致的痴呆比例以及特定临床病因-年-性别区域下的痴呆负担。并对未来10年进行了预测。使用GWAS数据库,收集血管性痴呆和17种危险因素的数据,并通过双样本MR分析确定因果关系。结果脑出血后痴呆的相对危险度(RR: 3.02[1.17-7.78], p < 0.001)高于脑梗死后痴呆的相对危险度(RR: 2.07[1.47-2.96], p < 0.001)。然而,由于脑梗死的高患病率,脑梗死所致痴呆的PAF高于脑出血。它们加起来解释了全球1.31%(1.41%-1.21%)的痴呆症。脑梗死和脑出血后痴呆的负担表现出明显的时空异质性。四种因果关系在双样本MR中被复制,脑脊液(CSF)代谢物X-11261的中介作用被两步MR确定。解释全球1%的痴呆患病率可以用缺血性中风和出血性中风来解释。量化由这两种情况引起的痴呆的比例有助于我们全面了解痴呆的原因。通过两样本MR研究和两步MR分析,确定与血管性痴呆相关的可改变危险因素和脑脊液介质,阐明预防或延缓痴呆典型特征的干预方法。这对今后的疾病预防和治疗工作至关重要。

Background and Purpose

Carotid endarterectomy (CEA) in symptomatic carotid stenosis (SCS) may have a higher risk of perioperative stroke due to disease severity or hemorrhagic conversion. This study aimed to evaluate CEA outcomes for SCS and examine causes of post-operative stroke based on intervention timing and preoperative symptoms.

Methods

All CEAs performed for SCS from 2012 to 2023 across two metropolitan hospitals were analyzed. CEAs were performed with general anesthesia, patching, and shunting. Post-operative (30-day) strokes were classified as technical, hemorrhagic, or embolic and were evaluated by timing (<48 h, 48h–2 weeks, >2 weeks) and preoperative symptoms (TIA/amaurosis fugax, minor stroke, moderate-severe stroke, crescendo TIAs/stroke in evolution). Stroke severity was assessed using the modified Rankin Scale (mRS).

Results

Among 664 CEAs, post-operative stroke occurred in 3.0 % of cases. Timing significantly influenced stroke rates: 5.7 % <48 h, 4.0 % between 48h–2 weeks, and 1.4 % >2 weeks (P = .04). Preoperative symptoms also affected stroke rates, with highest rates following crescendo TIAs/stroke in evolution (7.5 %, P = .02). Early CEA (<48 h) independently increased stroke risk (odds ratio 5.6, P = .04), and hemorrhagic strokes were associated with <48 h interventions (P = .005). Major strokes occurred in 1.1 % of cases, linked to preoperative symptoms (P = .05), but not intervention timing.

Conclusions

CEA for SCS carries an acceptable stroke risk overall, though early intervention (<48 h) increases hemorrhagic stroke risk. Major strokes are more frequent following crescendo TIA/stroke in evolution, with no association to timing.
背景与目的在症状性颈动脉狭窄(SCS)患者行颈动脉内膜切除术(CEA)可能由于疾病严重程度或出血转化而有较高的围手术期卒中风险。本研究旨在评估SCS的CEA结果,并根据干预时间和术前症状检查术后卒中的原因。方法分析2012 ~ 2023年两所城市医院收治的所有SCS的cea。在全麻、补片和分流的情况下进行cea。术后(30天)卒中分为技术性卒中、出血性卒中或栓塞性卒中,并通过时间(48小时、48小时- 2周、2周)和术前症状(TIA/烟性黑朦、轻微卒中、中重度卒中、逐渐加重的TIA/卒中)进行评估。采用改良Rankin量表(mRS)评估脑卒中严重程度。结果664例cea患者术后卒中发生率为3.0%。时间对卒中发生率有显著影响:48小时5.7%,48小时- 2周4.0%,2周1.4% (P = 0.04)。术前症状也影响卒中发生率,随着tia /卒中的发展,发生率最高(7.5%,P = 0.02)。早期CEA(48小时)独立增加卒中风险(优势比5.6,P = .04),出血性卒中与48小时干预相关(P = .005)。1.1%的病例发生严重中风,与术前症状有关(P = 0.05),但与干预时间无关。结论scea患者的卒中风险总体上是可接受的,但早期干预(48 h)会增加出血性卒中风险。在进化过程中,TIA/中风渐强后发生大中风的频率更高,与时间无关。

Objective

This study aimed to explore the association between ferroptosis markers and postoperative prognosis in patients with aneurysmal subarachnoid hemorrhage (aSAH) who underwent aneurysm clipping. Specifically, we evaluated the predictive value of ferroptosis markers in determining post-operative outcomes.

Methods

We conducted a prospective observational study involving 210 aSAH patients who underwent aneurysm clipping surgery at our institution from October 2021 to May 2023. Blood samples were collected at postoperative days 1, 3, 7, and 30 to assess the levels of ferroptosis markers (ACSL4, SLC7A11, GPX4) and inflammatory cytokines (CRP, IL-6, TNF-α) using enzyme-linked immunosorbent assay (ELISA). Clinical data were recorded at baseline. Postoperative prognosis was assessed using the modified Rankin Scale (mRS) at 30 days post-surgery. All patients included in the study underwent aneurysm clipping surgery as their primary treatment modality.

Results

The serum levels of ACSL4 and IL-6 were significantly higher in the mRS 3-6 group compared to the mRS 0-2 group at all time points. In contrast, SLC7A11 and GPX4 levels were significantly lower in the mRS 3-6 group. Spearman’s correlation analysis revealed a significant negative correlation between ACSL4 and GPX4 and a positive correlation between ACSL4 and IL-6 levels. ROC curve analysis demonstrated that ACSL4 had the highest predictive value for poor postoperative prognosis, with an area under the curve (AUC) of 0.757. Multivariate logistic regression analysis identified aneurysm size, GCS, SLC7A11, ACSL4, GPX4, and IL-6 as independent risk factors for poor postoperative prognosis.

Conclusion

Serum ferroptosis markers, particularly ACSL4, along with inflammatory markers, have significant potential in predicting the postoperative prognosis of aSAH patients. These markers could serve as useful biomarkers for early risk stratification and clinical decision-making in aSAH management.
目的:本研究旨在探讨动脉瘤性蛛网膜下腔出血(aSAH)患者行动脉瘤夹闭术后下垂铁标志物与术后预后的关系。具体来说,我们评估了铁下垂标志物在确定术后预后方面的预测价值。方法:我们进行了一项前瞻性观察研究,纳入了2021年10月至2023年5月在我院接受动脉瘤夹闭手术的210例aSAH患者。术后第1、3、7和30天采集血样,采用酶联免疫吸附试验(ELISA)评估铁下垂标志物(ACSL4、SLC7A11、GPX4)和炎症因子(CRP、IL-6、TNF-α)水平。基线时记录临床资料。术后30天采用改良Rankin评分(mRS)评估术后预后。所有纳入研究的患者均以动脉瘤夹闭手术作为主要治疗方式。结果:mRS 3 ~ 6组血清ACSL4、IL-6水平在各时间点均明显高于mRS 0 ~ 2组。mRS 3-6组SLC7A11和GPX4水平明显降低。Spearman相关分析显示ACSL4与GPX4呈显著负相关,而ACSL4与IL-6呈正相关。ROC曲线分析显示,ACSL4对术后不良预后的预测价值最高,曲线下面积(AUC)为0.757。多因素logistic回归分析发现动脉瘤大小、GCS、SLC7A11、ACSL4、GPX4、IL-6是术后不良预后的独立危险因素。结论:血清铁下垂标志物,尤其是ACSL4与炎症标志物对预测aSAH患者术后预后具有重要意义。这些标志物可作为aSAH早期风险分层和临床决策的有用生物标志物。
