RESUMEN

Worldwide, around 50 million people live with dementia, and this number is projected to triple by 2050. It has been estimated that 20% of all dementia cases have a predominant cerebrovascular pathology, while perhaps another 20% of vascular diseases contribute to a mixed dementia picture. Therefore, the vascular contribution to dementia affects 20 million people currently and will increase markedly in the next few decades, particularly in lower- and middle-income countries.In this review, we discuss the mechanisms of vascular cognitive impairment (VCI) and review management. VCI refers to the spectrum of cerebrovascular pathologies that contribute to any degree of cognitive impairment, ranging from subjective cognitive decline, to mild cognitive impairment, to dementia. While acute cognitive decline occurring soon after a stroke is the most recognized form of VCI, chronic cerebrovascular disease, in particular cerebral small-vessel disease, can cause insidious cognitive decline in the absence of stroke. Moreover, cerebrovascular disease not only commonly co-occurs with Alzheimer's disease (AD) and increases the probability that AD pathology will result in clinical dementia, but may also contribute etiologically to the development of AD pathologies.Despite its enormous health and economic impact, VCI has been a neglected research area, with few adequately powered trials of therapies, resulting in few proven treatments. Current management of VCI emphasizes prevention and treatment of stroke and vascular risk factors, with most evidence for intensive hypertension control. Reperfusion therapies in acute stroke may attenuate the risk of VCI. Associated behavioral symptoms such as apathy and poststroke emotionalism are common. We also highlight novel treatment strategies that will hopefully lead to new disease course-modifying therapies. Finally, we highlight the importance of including cognitive endpoints in large cardiovascular prevention trials and the need for an increased research focus and funding for this important area.

RESUMEN

BACKGROUND: Randomized controlled trials (RCTs) provide information on appropriate management protocols in patients with cerebrovascular diseases. Despite growing evidence of race and ethnicity being independent predictors of outcomes, recent literature has drawn attention to inadequate reporting of these demographic profiles across RCTs. To our knowledge, the adherence to reporting race and/or ethnicity in cerebrovascular RCTs remains undescribed. Our study describes trends in the reporting of race and/or ethnicity across cerebrovascular RCTs. METHODS: Web of Science was searched to identify the top 100-cited cerebrovascular RCTs. Additional articles were retrieved from guidelines issued by the American Heart Association for the management of ischemic stroke, intracerebral hemorrhage, and aneurysmal subarachnoid hemorrhage. Univariate and multivariate analyses were performed to assess for factors influencing reporting of race/ethnicity. RESULTS: Sixty-five percent of cerebrovascular RCTs lacked reporting of participant race and/or ethnicity. Multivariate regression revealed that studies from North America had a 14.74- fold higher odds (95% CI: 4.574-47.519) of reporting race/ethnicity. Impact factor of the journal was associated with 1.007-fold odds of reporting race/ethnicity (95% CI: 1.000-1.013). Reporting of race and/or ethnicity did not increase with time, or vary according to the number of participating centers, median number of study participants, source of funding, or category of RCT. Among RCTs that reported race, Blacks and Asians were underrepresented compared to Whites. CONCLUSIONS: Sixty-five percent of prominent cerebrovascular RCTs lack adequate reporting of participant race/ethnicity. Reasons for inadequate reporting of these variables remain unclear and warrant additional investigation.

RESUMEN

Vascular cognitive impairment (VCI) refers to cognitive impairment primarily mainly caused by cerebrovascular pathologies and their risk factors. It is the second leading cause of cognitive impairment in individuals aged 60 and above in China. Currently, there are no specific treatments for VCI, but early identification and prevention can help reduce the risk of onset and improve patients' prognosis. To raise awareness and attention among clinicians towards VCI and provide guidance for its standardized management, the Chinese Stroke Association Vascular Cognitive Impairment Subcommittee updated and revised the clinical classification, diagnostic procedures, neuropsychological evaluation criteria and imaging evaluation criteria and etc.on the basis of the Guidelines for the Diagnosis and Treatment of Vascular Cognitive Impairment in China (2019). Through systematic literature reviews, including meta-analysis, systematic review, randomized controlled trials, retrospective studies, clinical case-control studies, etc, evidence and recommendation levels were formulated according to the evaluation and evaluation criteria of recommendation classification, and a total of 8 recommendations were formed on the etiology, clinical classification, clinical manifestations, diagnostic criteria, prevention and treatment of VCI. A standardized diagnostic process for VCI suitable for the clinical practice in China was proposed, aiming at providing guidance for the standardized diagnosis and accurate treatment of VCI.

RESUMEN

The field of endovascular neurosurgery has experienced remarkable progress over the last few decades. Endovascular treatments have continued to gain traction as the advancement of technology, technique, and procedural safety has allowed for the expansion of treatment indications of various cerebrovascular pathologies. Interventions such as the coiling of intracranial aneurysms, carotid artery stenting, mechanical thrombectomy in the setting of ischemic stroke, and endovascular embolization of arteriovenous malformations have all seen transformations in their safety and efficacy, expanding the scope of endovascularly treatable conditions and offering new hope to patients who may have otherwise not been candidates for surgical intervention. Despite this notable progress, challenges persist, including complications associated with device deployment and questions regarding long-term outcomes. This article explores the advancements in endovascular neurosurgical techniques, highlighting the impact on patient care, outcomes, and the evolution of traditional surgical methods.

RESUMEN

BACKGROUND: Limited data are available on patients with chronic lung disease (CLD) presenting with acute myocardial infarction (AMI). We aimed to analyse baseline characteristics, treatment and outcome of those patients enrolled in the Swiss nationwide prospective AMIS Plus registry. METHODS: All AMI patients enrolled between January 2002 and December 2021 with data on CLD, as defined in the Charlson Comorbidity Index, were included. The primary endpoints were in-hospital mortality and major adverse cardiac and cerebrovascular events (MACCE), defined as all-cause death, reinfarction and cerebrovascular events. Baseline characteristics, in-hospital treatments and outcomes were analysed using descriptive statistics and logistic regression. RESULTS: Among 53,680 AMI patients enrolled during this time, 5.8% had CLD. Compared with patients without CLD, CLD patients presented more frequently with non-ST-elevation myocardial infarction (MI) and type 2 MI (12.8% vs. 6.5%, p < 0.001). With respect to treatment, CLD patients were less likely to receive P2Y12 inhibitors (p < 0.001) and less likely to undergo percutaneous coronary interventions (68.7% vs. 82.5%; p < 0.001). In-hospital mortality declined in AMI patients with CLD over time (from 12% in 2002 to 7.3% in 2021). Multivariable regression analysis showed that CLD was an independent predictor for MACCE (adjusted OR was 1.28 [95% CI 1.07-1.52], p = 0.006). CONCLUSION: Patients with CLD and AMI were less likely to receive evidence-based pharmacologic treatments, coronary revascularization and had a higher incidence of MACCE during their hospital stay compared to those without CLD. Over 20 years, in-hospital mortality was significantly reduced in AMI patients, especially in those with CLD.

RESUMEN

Advanced age is the major risk factor for dementia including Alzheimer's disease. The clinical effects of recently developed anti-amyloid therapy for Alzheimer's disease were modest and the long-term outcome is unknown. Thus, an in-depth understanding of the mechanisms of brain aging is essential to develop preventive interventions to maintain cognitive health in late life. Mounting evidence suggests that arterial aging manifested as increases in central arterial stiffness is associated closely with cerebrovascular dysfunction and brain aging while improvement of cerebrovascular function with aerobic exercise training contributes to brain health in older adults. We summarized evidence in this brief review that 1) increases in central arterial stiffness and arterial pulsation with age are associated with increases in cerebrovascular resistance, reduction in cerebral blood flow, and cerebrovascular dysfunction, 2) aerobic exercise training improves cerebral blood flow by modifying arterial aging as indicated by reductions in cerebrovascular resistance, central arterial stiffness, arterial pulsation, and improvement in cerebrovascular function, and 3) improvement in cerebral blood flow and cerebrovascular function with aerobic exercise training may lead to improvement in cognitive function. These findings highlight the associations between arterial aging and cerebrovascular function and the importance of aerobic exercise in maintaining brain health in older adults.

RESUMEN

OBJECTIVES: We aimed to investigate the associations between air pollutants and the risk of admission and multiple readmission events for cardiovascular disease (CVD). METHODS: A total of 285 009 participants free of CVD at baseline from the UK Biobank were included in this analysis. Four major cardiovascular admission events were identified during the follow-up: chronic ischaemic heart disease (CIHD), cerebrovascular disease, atrial fibrillation and heart failure. We used Prentice, Williams and Peterson-Total Time model to examine the association between ambient air pollution and first admission, as well as multiple readmissions for these CVDs. RESULTS: During a median follow-up of 12 years, 17 176 (6.03%) participants were hospitalised with CVDs, and 6203 (36.11%) patients with CVD had subsequent readmission events for CVDs. We observed significant associations between air pollution and both first admission and readmission for CVDs, with generally stronger associations on readmission for cardiovascular events. For example, the adjusted HRs for the first admission and subsequent readmission for cerebrovascular disease were 1.130 (95% CI 1.070 to 1.194) and 1.270 (95% CI 1.137 to 1.418) for each IQR increase of particulate matter with a diameter ≤2.5 µm. The corresponding HRs for CIHD were 1.060 (95% CI 1.008 to 1.114) and 1.120 (95% CI 1.070 to 1.171). Sex stratified analyses showed that the associations were generally more pronounced among females than males. CONCLUSION: This study provides evidence that ambient air pollutants might play an important role in both first admission and readmission for cardiovascular events. In addition, patients with pre-existing CVDs may be more vulnerable to air pollution compared with healthy population.

RESUMEN

The development of virtual care options, including virtual hospital platforms, is rapidly changing the healthcare, mostly in the pandemic period, due to difficulties in in-person consultations. For this purpose, in 2020, a neurological Virtual Hospital (NOVHO) pilot study has been implemented, in order to experiment a multidisciplinary second opinion evaluation system for neurological diseases. Cerebrovascular diseases represent a preponderant part of neurological disorders. However, more than 30% of strokes remain of undetermined source, and rare CVD (rCVD) are often misdiagnosed. The lack of data on phenotype and clinical course of rCVD patients makes the diagnosis and the development of therapies challenging. Since the diagnosis and care of rCVDs require adequate expertise and instrumental tools, their management is mostly allocated to a few experienced hospitals, making difficult equity in access to care. Therefore, strategies for virtual consultations are increasingly applied with some advantage for patient management also in peripheral areas. Moreover, health data are becoming increasingly complex and require new technologies to be managed. The use of Artificial Intelligence is beginning to be applied to the healthcare system and together with the Internet of Things will enable the creation of virtual models with predictive abilities, bringing healthcare one step closer to personalized medicine. Herein, we will report on the preliminary results of the NOVHO project and present the methodology of a new project aimed at developing an innovative multidisciplinary and multicentre virtual care model, specific for rCVD (NOVHO-rCVD), which combines the virtual hospital approach and the deep-learning machine system.

RESUMEN

BACKGROUND: Federal research funding is highly sought after but may be challenging to attain. A clear understanding of funding for specific diseases, such as cerebrovascular disorders, might help researchers regarding which National Institutes of Health (NIH) institutes fund research into specific disorders and grant types. OBJECTIVE: To examine the current scope of NIH grant funding for cerebrovascular conditions. METHODS: The NIH-developed RePORTER was used to extract active NIH-funded studies related to cerebrovascular diseases through January 2023. Duplicate studies were removed, and projects were manually screened and labeled in subcategories as clinical and basic science and as research subcategories. Extracted data included total funding, grant types, institutions that received funding, and diseases studied. Python (version 3.9) and SciPy library were used for statistical analyses. RESULTS: We identified 1232 cerebrovascular projects across seven diseases with US$699 952 926 in total funding. The cerebrovascular diseases with the greatest number of grants were ischemic stroke (705, or 57.2% of all funded projects), carotid disease (193, or 15.7%), and hemorrhagic stroke (163, or 13.2%). R01 grants were the most common mechanism of funding (632 grants, or 51.3%). The National Institute of Neurological Disorders and Stroke (NINDS) funded the most projects (504 projects; US$325 536 405), followed by the National Heart, Lung, and Blood Institute (NHLBI) (376 projects; US$216 784 546). CONCLUSION: Cerebrovascular disease receives roughly US$700 million in NIH funding. Ischemic stroke accounts for the majority of NIH-funded cerebrovascular projects, and R01 grants are the most common funding mechanism. Notably, NHLBI provides a large proportion of funding, in addition to NINDS.

RESUMEN

BACKGROUND: Interventional neuroradiology is a relatively recent discipline that diagnoses and treats cerebral vascular diseases. However, specific literature on cognitive and psychological domains of patients undergoing interventional neuroradiology procedures is limited. PURPOSE: Our aim was to review the existent literature on cognitive and psychological domains in patients undergoing interventional neuroradiology procedures to raise clinicians' awareness of their mental status. DATA SOURCES: Articles were searched in PubMed, EMBASE, and Scopus from 2000 to 2022 using terms such as "interventional neuroradiology," "psychology," and "cognition" according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. STUDY SELECTION: Of 1483 articles in English, 64 were included and analyzed. Twelve focused on psychological aspects; 52, on cognitive ones. DATA ANALYSIS: Regarding psychological aspects, it appears that early psychological consultations and "nonpharmacologic" strategies can impact the anxiety and depression of patients undergoing endovascular procedures. Regarding cognitive aspects, it appears that endovascular treatment is safe and generates similar or even fewer cognitive deficits compared with analogous surgical procedures. DATA SYNTHESIS: Among the 12 articles on psychological aspects, 6/12 were retrospective with one, while 6/12 were prospective. Among the 52 articles on cognitive aspects, 7/54 were retrospective, while 45/52 were prospective. LIMITATIONS: The main limitation derives from the inhomogeneity of the cognitive and psychological assessment tools used in the articles included in our analysis. CONCLUSIONS: Our review highlights the need to include cognitive and psychological assessments in clinical practice in case patients eligible for interventional neuroradiology procedures. In the future, much more research of and attention to cognitive and psychologic aspects of neurovascular disease is needed. Systematic incorporation of strategies and tools to access and address pre, peri-, and postprocedural psychological and cognitive components could have major benefits in patient satisfaction, recovery, and the success of endovascular practice.

RESUMEN

OBJECTIVE: To analyze the work of the Center for the Treatment of Cerebrovascular Pathology in Children and Adolescents, operating on the basis of the Morozov Children's City Clinical Hospital of the Moscow Health Department for the period 2018-2021 and to assess the peculiarities of organizing the provision of specialized care to children and adolescents with acute cerebrovascular accident (ACA). MATERIAL AND METHODS: Annual reports of the Center for the period 2018-2021; included children and adolescents aged 1 month to 17 years 11 months 29 days, with new onset ischemic stroke (IS) and hemorrhagic stroke (HS), cerebral venous thrombosis (sinus thrombosis), confirmed clinically and radiologically. RESULTS: Statistical data on stroke and organization of care for children with this pathology in Moscow are presented. The incidence of IS in Moscow for the period 2018-2021 ranged from 1.6 to 2.5 per 100.000 children, HI - from 2.35 to 3.3 per 100.000, sinus thrombosis from 0.5 to 1.38 per 100.000. When assessing the main etiological factors of stroke in The Center for International Pediatric Stroke Research categories, we noted a prevalence of chronic head and neck diseases (20-37%) and chronic systemic conditions (conditions or diseases with known changes in coagulation or vascular structure, including connective tissue dysplasia, genetic, hematological, inflammatory or diseases of the immune system) (15-20%). In addition, data on reperfusion therapy carried out at the Center are presented. From 2018 (first thrombolysis was performed) to 2021, 7.3-14.7% of all patients with IS underwent thrombolysis. CONCLUSION: The experience of functioning of the Center for the Treatment of Cerebrovascular Pathology in Children and Adolescents has shown that the creation of such centers in the regions of the Russian Federation is relevant, but requires taking into account the characteristics of the pediatric population when organizing their work.

RESUMEN

BACKGROUND: Despite an increase in the number of genes associated with pediatric stroke, imaging phenotypes in children have not been well reported. Guidelines are needed to facilitate the identification and treatment of patients with monogenic causes of cerebrovascular disorders. METHODS: We performed a retrospective review of imaging and medical records of patients aged zero to 21 years with monogenic causes of vascular malformations, small or large vessel disease, transient ischemic attacks, and/or ischemic or hemorrhagic stroke. We classified patients according to their imaging phenotype and reviewed neurological and systemic features and management strategies. We reviewed the literature to identify genes associated with cerebrovascular disorders presenting in childhood. RESULTS: We identified 18 patients with monogenic causes of cerebrovascular disorders and classified each patient as belonging to one or more of three cerebrovascular phenotypes according to predominant imaging characteristics: small vessel disease, large vessel disease, and/or vascular malformations. Preventative treatments included aspirin, N-acetylcysteine, tocilizumab, therapeutic low-molecular-weight heparin, and resection of vascular malformations. CONCLUSIONS: Classifying pediatric patients with cerebrovascular disorders by imaging phenotype can aid in determining the next steps in genetic testing and treatment.

RESUMEN

Pregnancy is a risk factor for cerebrovascular disease owing to pregnancy-related hormonal changes, a hypercoagulable state, maternal hemodynamic changes, and changes in the vascular wall. Cerebral hemorrhage and other cerebrovascular disorders account for 14% of all maternal deaths and represent the second most common cause of death after obstetric hemorrhage (38%). The timing of pregnancy-related cerebrovascular disorders. The 2008 Health and Labor Sciences Study on Pregnancy-Related Cerebrovascular Disorders (principal investigator Tomoaki Ikeda) was performed across 115 facilities between January and December 2006. The study included 184 cases of pregnancy-related cerebrovascular disorders; 39 cases of cerebral hemorrhage, 18 of subarachnoid hemorrhage, 25 of cerebral infarction, 5 of cerebral venous sinus thrombosis, and 2 cases of eclampsia and hypertensive encephalopathy. vascular disease, resulting in venous stasis, focal cerebral edema, and eventually hemorrhagic venous infarction. Ruptured cerebral aneurysms that lead to subarachnoid hemorrhage during pregnancy should be treated surgically on an emergency basis.

RESUMEN

BACKGROUND: Cerebrovascular disease is a significant cause of morbidity and mortality in Africa, and using neuroimaging techniques has improved the diagnosis and management of this disease. However, there is a lack of comprehensive reviews of the role and effectiveness of neuroimaging techniques in the African context. METHODS: We reviewed the literature to evaluate the role of neuroimaging in diagnosing and managing cerebrovascular disease in Africa. Our search included electronic databases such as PubMed, Scopus, and Google Scholar from 2000 to April 2023. We included peer-reviewed studies written in English that reported on the use of neuroimaging in diagnosing and managing cerebrovascular disease in African populations. We excluded non-peer-reviewed articles, letters, editorials, and studies unrelated to cerebrovascular disease, neuroimaging, or Africa. A total of 102 potential articles were identified; after applying our exclusion criteria and removing duplicated articles, 51 articles were reviewed. RESULTS: Our findings suggest that neuroimaging techniques such as CT, MRI, and Skull x-ray play a crucial role in diagnosing and managing cerebrovascular disease in Africa. CT and MRI were the most commonly used techniques, with CT being more widely available and less expensive than MRI. However, challenges to using neuroimaging in Africa include the high cost of equipment and maintenance, lack of trained personnel, and inadequate infrastructure. These challenges limit the widespread use of neuroimaging in diagnosing and managing cerebrovascular disease in Africa. CONCLUSION: Neuroimaging techniques are essential for diagnosing and managing cerebrovascular disease in Africa, but challenges to their use must be addressed to improve healthcare outcomes. Our policy recommendations can help improve the availability and accessibility of neuroimaging services in Africa.

RESUMEN

Ischemic stroke caused by acute large vessel occlusion is associated with high rates of disability and mortality. Endovascular interventional therapy is evidently an effective treatment for occlusion of large cerebral vessels within the relevant time window, but there is no established methodological standard for recanalization interventional therapy. The Professional Committee of Interventional Neurology in Chinese Research Hospital Association organized cerebrovascular disease experts in China and developed the expert consensus described herein, to provide a reference for clinicians to formulate technical strategies for recanalization of acute cerebral vascular occlusion.

RESUMEN

Introduction: The telephone triage service is an emergency medical system through which citizens consult telephone triage nurses regarding illness, and the nurses determine the urgency and need for an ambulance. Despite being introduced in several countries, its impact on emergency patients has not been reported. We aimed to determine the effect of the telephone triage service on the outcomes of hospitalized patients diagnosed with cerebrovascular disease upon arrival after being transported by an ambulance. Methods: This retrospective study included patients with cerebrovascular disease who were transported by ambulance between January 2016 and December 2019. The primary outcome was discharge to home by day 21 of hospitalization. A total of 344 patients who used the telephone triage service were propensity score-matched to 344 patients who directly called for an ambulance. Results: Telephone triage service use was associated with discharge to home by hospital day 21 (crude odd ratio: 1.8; 95% confidence interval: 1.3-2.4) and was not significantly associated with survival on hospital day 21 in multivariate regression analysis. Conclusion: The prognoses of cerebral infarction, intracerebral hemorrhage, and subarachnoid hemorrhage depend on the time from symptom onset to treatment. Telephone triage services may allow patients to receive treatment more rapidly than traditional ambulance requests, resulting in improved patient outcomes. The findings of this study suggest that the use of telephone triage services is associated with improved outcomes in patients with cerebrovascular disease and indicate that the costs for medical expenses and disability may be greatly reduced in an aging society.

RESUMEN

Cardiovascular and cerebrovascular diseases (CCVDs) are two major vasculature-related diseases that seriously affect public health worldwide, which can cause serious death and disability. Lack of targeting effect of the traditional CCVD treatment drugs may damage other tissues and organs, thus more specific methods are needed to solve this dilemma. Micro/nanomotors are new materials that can convert external energy into driving force for autonomous movement, which can not only enhance the penetration depth and retention rates, but also increase the contact areas with the lesion sites (such as thrombus and inflammation sites of blood vessels). Physical field-regulated micro/nanomotors using the physical energy sources with deep tissue penetration and controllable performance, such as magnetic field, light, and ultrasound, etc. are considered as the emerging patient-friendly and effective therapeutic tools to overcome the limitations of conventional CCVD treatments. Recent efforts have suggested that physical field-regulated micro/nanomotors on CCVD treatments could simultaneously provide efficient therapeutic effect and intelligent control. In this review, various physical field-driven micro/nanomotors are mainly introduced and their latest advances for CCVDs are highlighted. Last, the remaining challenges and future perspectives regarding the physical field-regulated micro/nanomotors for CCVD treatments are discussed and outlined.
