Abstract
Aim: Tuberculous meningitis (TBM) often causes cerebral infarction, but its predictive factors are not well understood. Methods: Patients aged ≥13 years admitted with TBM were enrolled prospectively. Cerebral infarction was diagnosed using magnetic resonance imaging. Results: Of 186 patients, 80 (43%) had infarction. Most infarctions were multiple and located in the cortical areas, basal ganglia and subcortical regions. Independent predictors of infarction at admission included high blood pressure, short illness duration, low Glasgow coma scale and hydrocephalus. Neuroimaging inflammation signs, cerebrospinal fluid analysis abnormalities and pre-existing cardiovascular risks did not predict infarction. In-hospital mortality was higher in TBM with infarction, particularly in those with advanced TBM (stage 3). Conclusion: Baseline parameters of raised intracranial pressure predict cerebral infarction in TBM.

Yang Q, Chang A, Tong X, Jackson SL, Merritt RK. Long-term cardiovascular disease outcomes in non-hospitalized medicare beneficiaries diagnosed with COVID-19: Population-based matched cohort study. PLoS One 2024; 19:e0302593. [PMID: 38743728 PMCID: PMC11093379 DOI: 10.1371/journal.pone.0302593] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Accepted: 04/08/2024] [Indexed: 05/16/2024] Open
Abstract
BACKGROUND SARS-CoV2, the virus that causes coronavirus disease 2019 (COVID-19), can affect multiple human organs structurally and functionally, including the cardiovascular system and brain. Many studies focused on the acute effects of COVID-19 on risk of cardiovascular disease (CVD) and stroke especially among hospitalized patients with limited follow-up time. This study examined long-term mortality, hospitalization, CVD and stroke outcomes after non-hospitalized COVID-19 among Medicare fee-for-service (FFS) beneficiaries in the United States. METHODS This retrospective matched cohort study included 944,371 FFS beneficiaries aged ≥66 years diagnosed with non-hospitalized COVID-19 from April 1, 2020, to April 30, 2021, and followed-up to May 31, 2022, and 944,371 propensity score matched FFS beneficiaries without COVID-19. Primary outcomes were all-cause mortality, hospitalization, and incidence of 15 CVD and stroke. Because most outcomes violated the proportional hazards assumption, we used restricted cubic splines to model non-proportional hazards in Cox models and presented time-varying hazard ratios (HRs) and Bonferroni corrected 95% confidence intervals (CI). RESULTS The mean age was 75.3 years; 58.0% women and 82.6% non-Hispanic White. The median follow-up was 18.5 months (interquartile range 16.5 to 20.5). COVID-19 showed initial stronger effects on all-cause mortality, hospitalization and 12 incident CVD outcomes with adjusted HRs in 0-3 months ranging from 1.05 (95% CI 1.01-1.09) for mortality to 2.55 (2.26-2.87) for pulmonary embolism. The effects of COVID-19 on outcomes reduced significantly after 3-month follow-up. Risk of mortality, acute myocardial infarction, cardiomyopathy, deep vein thrombosis, and pulmonary embolism returned to baseline after 6-month follow-up. Patterns of initial stronger effects of COVID-19 were largely consistent across age groups, sex, and race/ethnicity. CONCLUSIONS Our results showed a consistent time-varying effects of COVID-19 on mortality, hospitalization, and incident CVD among non-hospitalized COVID-19 survivors.

Abstract
BACKGROUND The association of a broad spectrum of infectious diseases with cardiovascular outcomes remains unclear. OBJECTIVES We aim to provide the cardiovascular risk profiles associated with a wide range of infectious diseases and explore the extent to which infections reduce life expectancy. METHODS We ascertained exposure to 900+ infectious diseases before cardiovascular disease (CVD) onset in 453,102 participants from the UK Biobank study. Time-varying Cox proportional hazard models were used. Life table was used to estimate the life expectancy of individuals aged ≥50 with different levels of infection burden (defined as the number of infection episodes over time and the number of co-occurring infections). RESULTS Infectious diseases were associated with a greater risk of CVD events (adjusted HR [aHR] 1.79 [95% confidence interval {CI} 1.74-1.83]). For type-specific analysis, bacterial infection with sepsis had the strongest risk of CVD events [aHR 4.76 (4.35-5.20)]. For site-specific analysis, heart and circulation infections posed the greatest risk of CVD events [aHR 4.95 (95% CI 3.77-6.50)], whereas noncardiac infections also showed excess risk [1.77 (1.72-1.81)]. Synergistic interactions were observed between infections and genetic risk score. A dose-response relationship was found between infection burden and CVD risks (p-trend <0.001). Infection burden >1 led to a CVD-related life loss at age 50 by 9.3 years [95% CI 8.6-10.3]) for men and 6.6 years [5.5-7.8] for women. CONCLUSIONS The magnitude of the infection-CVD association showed specificity in sex, pathogen type, infection burden, and infection site. High genetic risk and infection synergistically increased the CVD risk.

Tanaka K, Demchuk AM, Malo S, Hill MD, Holodinsky JK. Risk of stroke within 3, 7, 14, 21 and 30 days after influenza vaccination in Alberta, Canada: A population-based study. Eur J Neurol 2024; 31:e16172. [PMID: 38117538 PMCID: PMC11236019 DOI: 10.1111/ene.16172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 11/09/2023] [Accepted: 11/20/2023] [Indexed: 12/21/2023]
Abstract
BACKGROUND AND PURPOSE Influenza vaccination is associated with a longer-term protective effect against stroke; however, it has a short-term inflammatory response which may increase short-term risk of stroke. The aim was to investigate the association between influenza vaccination and short-term risk of stroke in adults. METHODS Administrative data were obtained from the Alberta Health Care Insurance Plan for all adults in Alberta, Canada, from September 2009 to December 2018. The hazard of any stroke (acute ischaemic stroke, intracerebral haemorrhage, subarachnoid haemorrhage and transient ischaemic attack) within 3, 7, 14, 21 and 30 days of influenza vaccination compared to unexposed time was analysed using Andersen-Gill Cox models, with adjustment for age, sex, anticoagulant use, atrial fibrillation, chronic obstructive pulmonary disease, diabetes, hypertension, income quintile, and rural or urban home location. RESULTS In the entire cohort consisting of 4,141,209 adults (29,687,899 person-years), 1,769,565 (42.7%) individuals received at least one vaccination. In total 38,126 stroke events were recorded with 1309 occurring within 30 days of a vaccination event. Influenza vaccination was associated with a significantly reduced hazard of stroke within 3 days (hazard ratio [HR] 0.83, 95% confidence interval [CI] 0.73-0.93), 7 days (HR 0.87, 95% CI 0.80-0.95), 14 days (HR 0.87, 95% CI 0.81-0.93), 21 days (HR 0.85, 95% CI 0.80-0.91) and 30 days (HR 0.66, 95% CI 0.65-0.68). CONCLUSIONS An increased early risk associated with vaccination was not observed. The risk of stroke was reduced at all time points within 30 days after influenza vaccination.

Abstract
BACKGROUND Although patients with COVID-19 have a higher risk of acute ischemic stroke (AIS), the impact on stroke outcomes remains uncertain. AIMS To determine the clinical outcomes of patients with AIS and COVID-19 (AIS-COVID+). METHODS We performed a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Our protocol was registered with the International Prospective Register of Systematic Reviews (CRD42020211977). Systematic searches were last performed on June 3, 2021 in EMBASE, PubMed, Web-of-Science, Scopus, and CINAHL Databases. INCLUSION CRITERIA (1) studies reporting outcomes on AIS-COVID+; (2) original articles published in 2020 or later; (3) study participants aged ≥18 years. EXCLUSION CRITERIA (1) case reports with <5 patients, abstracts, review articles; (2) studies analyzing novel interventions. Risk of bias was assessed using the Mixed Methods Appraisal Tool. Random-effects models estimated the pooled OR and 95% confidence intervals (95% CI) for mortality, modified Rankin Scale (mRS) score, length of stay (LOS), and discharge disposition. RESULTS Of the 43 selected studies, 46.5% (20/43) reported patients with AIS without COVID-19 (AIS-COVID-) for comparison. Random-effects model included 7294 AIS-COVID+ and 158 401 AIS-COVID-. Compared with AIS-COVID-, AIS-COVID+ patients had higher in-hospital mortality (OR=3.87 (95% CI 2.75 to 5.45), P<0.001), less mRS scores 0-2 (OR=0.53 (95% CI 0.46 to 0.62), P<0.001), longer LOS (mean difference=4.21 days (95% CI 1.96 to 6.47), P<0.001), and less home discharge (OR=0.31 (95% CI 0.21 to 0.47), P<0.001). CONCLUSIONS Patients with AIS-COVID had worse outcomes, with almost fourfold increased mortality, half the odds of mRS scores 0-2, and one-third the odds of home discharge. These findings confirm the significant impact of COVID-19 on early stroke outcomes.

Abstract
We present a case of a 30-year-old male who was admitted with Streptococcus pneumoniae meningitis. He initially responded well to antibiotic therapy. However, the patient later developed symptomatic sinus bradycardia, which was likely due to intracranial hypertension. Even though the patient showed overt symptoms, vigilant monitoring, interdisciplinary collaboration, and cardiac evaluation helped avoid unnecessary interventions. This case highlights the importance of recognizing and managing rare cardiac complications associated with central nervous system infections.

Abstract
Vasculitis is a complication of several infectious diseases affecting the central nervous system, which may result in ischemic and/or hemorrhagic stroke, transient ischemic attack, and aneurysm formation. Infectious agents may directly infect the endothelium causing vasculitis or indirectly affect the vessel wall through an immunological cascade. Clinical manifestations usually overlap with those of noninfectious vascular diseases, making diagnosis challenging. Neuroimaging enables the identification of inflammatory changes in intracranial vasculitis. In this article, we review the imaging features of infectious vasculitis of bacterial, viral, fungal and parasitic causes.

Abstract
OBJECTIVES Medical tourism is expanding globally, with patients seeking cosmetic procedures abroad. To date, little information is known regarding the risks and outcomes of cosmetic tourism, especially potential stroke complications. Here, we present a case of fungal meningitis in the setting of medical tourism leading to ischemic strokes and vasospasm. MATERIAL AND METHODS We describe an immunocompetent 29-year-old female patient who initially presented with intractable headaches and an abnormal cerebrospinal fluid (CSF) profile who was eventually diagnosed with Fusarium solani meningitis as a part of a common source outbreak in Matamoros, Mexico. These patients were part of a cohort who underwent cosmetic procedures requiring spinal anesthesia. This report also highlights the unusual clinical course leading to poor outcomes in such conditions. RESULTS The patient initially presented with headaches, papilledema, elevated opening pressure on the spinal tap, abnormal CSF studies, and eventually developed ischemic strokes and hydrocephalus. CSF showed positive beta D-Glucan with repeated negative CSF fungal cultures. A cerebral angiogram revealed extensive basilar artery vasospasm that led to ischemic strokes. Continued clinical worsening and lack of response to antifungal treatment prompted further imaging that revealed significant non-obstructive hydrocephalus subsequently complicated by spontaneous intracranial hemorrhage. CSF PCR for Fusarium solani species was positive days after her passing. CONCLUSION This novel case highlights fungal meningitis caused by Fusarium solani complicated by bilateral ischemic strokes stemming from basilar artery vasospasm. Complications from medical tourism impact not only individual patients but also the health systems of both countries. Professional and regulatory entities for cosmetic surgeries must highlight and educate patients on the risks and complications of cosmetic surgeries happening abroad. Physicians should be aware of ongoing outbreaks and possible complications of these procedures.

Abstract
Respiratory viral infections have been found to have a negative impact on neurological functions, potentially leading to significant neurological impairment. The SARS-CoV-2 virus has precipitated a worldwide pandemic, posing a substantial threat to human lives. Growing evidence suggests that SARS-CoV-2 may severely affect the CNS and respiratory system. The current prevalence of clinical neurological issues associated with SARS-CoV-2 has raised significant concerns. However, there needs to be a more comprehensive understanding of the specific pathways by which SARS-CoV-2 enters the nervous system.

Kumar VS, Kumar VS. Localization of cerebral vasculopathy following bacterial meningitis: What can we learn about postinfective ischemic sequelae? Brain Circ 2023; 9:205-213.

Abstract
Cerebrovascular complications of bacterial meningitis account for a high incidence of mortality and postinfective neurologic sequelae. Cerebrovascular complications occurring during acute bacterial meningitis are evident from angiographic evidence demonstrating arterial occlusion and vessel wall narrowing, histopathological studies demonstrating vessel wall changes, and radiographic studies demonstrating the presence of brain infarcts. Cerebrovascular disease during bacterial meningitis has been demonstrated in of Haemophilus influenzae, Streptococcus pneumonia, Group B Streptococcus, and Mycobacterium tuberculosis models of meningitis. Despite models of bacterial meningitis showing variable patterns of cerebral vasculopathy as a contributor to different aspects of postinfectious neurological decline, very few studies describe the predominant localization of cerebral vasculopathy with different meningitis causing pathogens. Thus, this review attempts to analyze the different locations of cerebral vasculopathic changes occuring in response to different microbial pathogens and provide a pathophysiologic basis for such an observation.

Abstract
The World Health Organization (WHO) South East Asia Region (SEAR) comprises 11 countries, which are one of the most culturally, topographically, and socially diverse areas worldwide, undergoing an epidemiological transition towards non-communicable diseases, including stroke and other cardiovascular diseases (CVDs). This region accounts for over 40% of the global stroke mortality. Few well-designed population-based epidemiological studies on stroke are available from SEAR countries, with considerable variations among them. Ischemic stroke, a common stroke subtype, has higher frequencies of intracerebral hemorrhage in many countries. Along with an aging population, the increased prevalence of risk factors such as hypertension, diabetes mellitus, tobacco and alcohol consumption, lack of physical activity, high ambient pollution, heat, and humidity contribute to the high burden of stroke in this region. SEAR's many unique and uncommon stroke etiologies include cerebral venous thrombosis, tuberculosis, dengue, scrub typhus, falciparum malaria, snake bite, scorpion sting, etc. Current data on stroke burden and risk factors is lacking, compelling an urgent need for high-quality hospital-level and population-level data in all SEAR countries. Strategies towards a consolidated approach for implementing improved stroke prevention measures, stroke surveillance, and established stroke systems of care are the path to bridging the gaps in stroke care.

Abstract
Primary intestinal lymphangiectasia (Waldmann's disease) is a rare exudative enteropathy without precisely assessed infectious risk. We report the case of a 49-year-old male patient with meningitis and cerebral vasculitis due to Cryptococcus neoformans complicating Waldmann's disease diagnosed 12 years ago. The treatment combined liposomal amphotericin B, 3 mg/kg daily plus flucytosine 25 mg/kg/6 h, both intravenously during 15 days, then fluconazole 800 mg daily during 8 weeks, and finally 200 mg daily indefinitely. Dexamethasone 0.4 mg/kg daily during the first week was gradually decreased over 2 months. The outcome was good, and the patient is still followed 3 years later without any recurrence.

Abstract
Central nervous system (CNS) may be predisposed to devastating complications in cancer patients which may add to morbidity and mortality in this group. Majority of the complications are vascular in nature due to the altered coagulation profile and pro-inflammatory state in these patients. However, there are a host of other conditions which may affect the clinical course of these patients including metabolic and toxic encephalopathies, infections, and paraneoplastic syndromes. Moreover, multimodality management of these patients, which is often used in majority of the cancers, exposes them to treatment related complications. This pictorial review aims to enlighten the reader regarding the various complications affecting the CNS as seen at our tertiary cancer care institute. We aim to highlight the emergent nature of these complications and the need to identify them quickly and accurately on imaging which helps to institute early appropriate management and prevents further morbidity and mortality.

Abstract
Neurosyphilis occurs when the spirochete Treponema pallidum invades the cerebrospinal fluid (CSF). Clinical presentation depends on an individual's immune response and invasion location, with all possible involvement of meningeal, vascular, and/or parenchymatous tissues. Meningovascular neurosyphilis occurs when both the meninges and vasculature are affected and can lead to headaches, photophobia, neck stiffness, cranial nerve palsies, and/or ischemic brain infarctions due to infectious arteritis. The following report describes the rare case of a 32-year-old male patient presenting with multiple ischemic brain infarctions of varying ages. The stepwise diagnostic approach as described allowed the medical team to reach the final diagnosis of meningovascular neurosyphilis with concomitant acquired immunodeficiency syndrome (AIDS). This case emphasizes the importance of maintaining high clinical suspicion in all young adult patients who present with acute neurological deficits.

Abstract
Background and Aims In recent years, various studies have been conducted worldwide to investigate the relationship between receiving the flu vaccine with acute cerebrovascular accident or stroke and its hospitalization in the elderly; however, the results of these studies are contradictory. Therefore, this study was aimed at investigating the relationship between receiving the flu vaccine with stroke and its hospitalization in the elderly. Methods This study is a systematic review and meta-analysis of studies examining the relationship between receiving the flu vaccine with stroke and its hospitalization in the elderly during the years 1980 to 2021 which have been published in ISI Web of Science, Scopus PubMed, Cochrane, Science Direct, Google Scholar, and Embase. All analyses were performed by Stata 15, and the significance level in this study was considered <0.05. Results In the systematic search, 3088 articles were retrieved, considering the study criteria; finally, 14 studies were included in the meta-analysis. Based on the results of the meta-analysis, the odds ratio (OR) of occurrence and hospitalization of stroke compared to the nonvaccinated group in vaccine recipients is equal to 0.84 (95% confidence interval (CI): 0.78-0.90, P value ≤ 0.001). Publication bias was not observed in this study (P value = 0.101). Conclusion Getting the flu vaccine can reduce the risk of occurrence and hospitalization of stroke in the elderly by 16% (10%-22%). Therefore, receiving this vaccine as a preventive intervention for stroke in the elderly may be promising.

Abstract
Thrombosis remains a major problem in our society, manifesting across multiple demographic groups and with high associated morbidity and mortality. Thrombus development is the result of a complex mechanism in which multiple cell types and soluble factors play a crucial role. One cell that has gained the most attention in recent years is the neutrophil. This key member of the innate immune system can form neutrophil extracellular traps (NETs) in response to activating stimuli in circulation. NETs form a scaffold for thrombus formation, both initiating the process and stabilizing the final product. As the first responders of the host immune system, neutrophils have the flexibility to recognize a variety of molecules and can quickly interact with a range of different cell types. This trait makes them sensitive to exogenous stimuli. NET formation in response to pathogens is well established, leading to immune-mediated thrombus formation or immunothrombosis. NETs can also be formed during sterile inflammation through the activation of neutrophils by fellow immune cells including platelets, or activated endothelium. In chronic inflammatory settings, NETs can ultimately promote the development of tissue fibrosis, with organ failure as an end-stage outcome. In this review, we discuss the different pathways through which neutrophils can be activated toward NET formation and how these processes can result in a shared outcome: thrombus formation. Finally, we evaluate these different interactions and mechanisms for their potential as therapeutic targets, with neutrophil-targeted therapies providing a future approach to treating thrombosis. In contrast to current practices, such treatment could result in reduced pathogenic blood clot formation without increasing the risk of bleeding.

Abstract
Background Cryptococcal meningoencephalitis (CM), is a highly fatal fungal infection of the central nervous system (CNS), affecting not only immunocompromised patients, but also apparently immunocompetent patients. CM is mainly caused by Cryptococcus neoformans (C. neoformans), while viral hepatitis B (HBV) tends to be a rare inducement. According to the literature, the most common cerebral area affected by CM was frontal lobe, while infratentorial lesions were rare, especially those complicated with cerebellar infarction. Methods This study capitally analyzed the clinical data of an elderly female suffering from infratentorial CM complicated with cerebellar infarction, with a history of chronic HBV. Results The patient suffered from the symptoms of dizziness, insanity, low-grade fever, and high cranial pressure throughout the course of the disease. Her MRI findings were hydrocephalus and infratentorial lesions, including bilateral cerebellums and meningeal enhancement. The pathogene was Cryptococcus revealed by both the cytology and ink stain of cerebrospinal fluid, and was confirmed to be C. neoformans by the Next generation sequencing (NGS). After 12 days of intravenous amphotericin B (AMB) treatment, the patient developed oliguria, and 3 days after the termination of AMB treatment, the renal function recovered. Brain MRI reexamination after the treatment showed that the diffused lesions in the cerebellum were significantly decreased, and acute infarction occurred on the left cerebellum although it was asymptomatic. The patient took fluconazole 400mg per day after discharge, without complaints during the follow-up two months later. Conclusion C. neoformans infection may be a possible pathogeny in chronic HBV patients with meningoencephalitis. Cerebellar infarction might be a complication of CM, therefore MRI is supposed to be re-examined during antifungal therapy. Additionally, monitoring renal function plays a vital role after AMB treatment, and renal function may recover after termination.

Abstract
Acute lesions of the central nervous system often lead to permanent limiting deficits. In addition to the initial primary damage, accompanying neuroinflammation is responsible for progression of damage. Mycophenolate mofetil (MMF) as a selective inhibitor of inosine 5-monophosphate dehydrogenase (IMPDH) was shown to modulate the inflammatory response and promote neuronal survival when applied in specific time windows after neuronal injury. The application of brain cytoprotective therapeutics early after neuronal damage is a fundamental requirement for a successful immunomodulation approach. This study was designed to evaluate whether MMF can still mediate brain cytoprotection when applied in predefined short time intervals following CNS injury. Furthermore, the role of microglia and changes in IMPDH2 protein expression were assessed. Organotypic hippocampal slice cultures (OHSC) were used as an in vitro model and excitotoxically lesioned with N-methyl-aspartate (NMDA). Clodronate (Clo) was used to deplete microglia and analyze MMF mediated microglia independent effects. The temporal expression of IMPDH2 was studied in primary glial cell cultures treated with lipopolysaccharide (LPS). In excitotoxically lesioned OHSC a significant brain cytoprotective effect was observed between 8 and 36 h but not within 8 and 24 h after the NMDA damage. MMF mediated effects were mainly microglia dependent at 24, 36, 48 h after injury. However, further targets like astrocytes seem to be involved in protective effects 72 h post-injury. IMPDH2 expression was detected in primary microglia and astrocyte cell cultures. Our data indicate that MMF treatment in OHSC should still be started no later than 8–12 h after injury and should continue at least until 36 h post-injury. Microglia seem to be an essential mediator of the observed brain cytoprotective effects. However, a microglia-independent effect was also found, indicating involvement of astrocytes.

Abstract
Background Stroke is considered as one of the most important concerns in health care centers around the world. By definition there are two types of stroke including ischemic stroke and hemorrhagic stroke. Approximately three-quarters of stroke cases are ischemic strokes, which occur due to several risk factors such as hypertension, obesity, atherosclerosis, diabetes mellitus, osteoarthritis, and inflammatory responses. In recent years, infectious diseases have noticed as a new risk factor for ischemic stroke. Given the importance of the issue, some bacteria that cause chronic infections, especially Chlamydia pneumonia, Helicobacter pylori, Mycoplasma pneumonia, Mycobacterium tuberculosis, and Coxiella burnetii have been considered. Methods In the present meta-analysis, we reviewed 50 case-control studies and assessed the possible association of bacterial infections with the occurrence of ischemic stroke. Results We analyzed the information of 33,978 participants in several nested case-control studies, and ultimately showed that bacterial infections could increase the risk of ischemic stroke. Our results suggest that bacterial infections significantly increase in the risk of ischemic stroke (OR: 1.704; 1.57-1.84 with 95% CIs; p value = 0.01). Conclusions In this meta-analysis, a significant relationship was observed between infection by three bacteria such as C. pneumoniae, H. pylori, and M. tuberculosis with the occurrence of ischemic stroke. Furthermore, due to the similarity between TLRVYK domain in β2-glycoprotein-I and TLRVYK peptide in various of microorganisms, produced antibodies against pathogens interact with β2-glycoprotein-I, hence the cross-reaction phenomenon increases the positive relationship between infectious diseases and ischemic stroke.

Abstract
The prevalence of vascular diseases in HIV (human immunodeficiency virus)-infected individuals has been comprehensively investigated. However, their incidence of ischemic cerebrovascular events has not been thoroughly examined. Our aim was to examine the rate of ischemic stroke or TIA (transient ischemic attack) in a defined HIV population and to find the risk factors that are characteristic in this population. A case-controlled retrospective cohort study of HIV patients followed up at Kaplan Medical Center between 2009 and 2017 was performed. The study included 300 patients who had been compared to a matched age and gender group. The data were collected by reviewing patients' files and imaging studies. The first goal was to compare the incidence of ischemic cerebrovascular events in both groups. Secondary endpoints were to characterize the types of cerebrovascular events and risk factors in the study group versus the general population. There were more ischemic stroke cases in the study group vs. the control group. After adjusting for vascular risk factors in a multivariate analysis, the odds ratio for a cerebrovascular accident in the HIV patient group was 2.29 (p = 0.057). Notably, in the comparative group, the vascular risk factors' rate (hyperlipidemia, IHD and smoking) was higher than in the HIV group. In this study, ischemic cerebrovascular events were more common in HIV-infected patients than in the control group, in spite of the fact that they had fewer vascular risk factors.

Abstract
Infections are an underappreciated cause of stroke, particularly in young and immunocompromised individuals. Varicella-zoster virus (VZV) reactivation, particularly ophthalmic zoster, has been linked to increased risk of stroke but diagnosing VZV-associated cerebral vasculopathy is challenging as neither a recent Zoster rash, nor detectable levels of VZV DNA are universally present at stroke presentation. Detection of VZV IgG in cerebrospinal fluid (CSF-VZVG) presents a promising alternative, but requires evaluation of individual blood-CSF dynamics, particularly in the setting of chronic inflammatory states such as HIV infection. Consequently, its use has not been broadly adopted as simple diagnostic algorithms are not available. In this study looking at young adults presenting with acute stroke, we used an algorithm that includes testing for both VZV nucleic acids and CSF-VZVG which was corrected for blood-CSF barrier dynamics and poly-specific immune activation. We found that 13 of 35 (37%), including 7 with a positive CSF VZV PCR, young HIV-infected adults presenting with stroke, 3 of 34 (9%) young HIV-uninfected adults presenting with stroke and 1 of 18 (6%) HIV-infected non-stroke controls demonstrated evidence of central nervous system reactivation of VZV.

Neurology 2022; 98:e778-e789. [PMID: 35115387 DOI: 10.1212/wnl.0000000000013184] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Accepted: 11/30/2021] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Findings of association between COVID-19 and stroke remain inconsistent, ranging from significant association, absence of association to less than expected ischemic stroke among hospitalized patients with COVID-19. The present study examined the association between COVID-19 and risk of acute ischemic stroke (AIS). METHODS We included 37,379 Medicare fee-for-service (FFS) beneficiaries aged ≥65 years diagnosed with COVID-19 from April 1, 2020 through February 28, 2021 and AIS hospitalization from January 1, 2019 through February 28, 2021. We used a self-controlled case series design to examine the association between COVID-19 and AIS and estimated the incident rate ratios (IRR) by comparing incidence of AIS in risk periods (0-3, 4-7, 8-14, 15-28 days after diagnosis of COVID-19) vs. control periods. RESULTS Among 37,379 Medicare FFS beneficiaries with COVID-19 and AIS, the median age at diagnosis of COVID-19 was 80.4 (interquartile range 73.5-87.1) years and 56.7% were women. When AIS at day of exposure (day=0) included in the risk periods, IRRs at 0-3, 4-7, 8-14, and 15-28 days following COVID-19 diagnosis were 10.3 (95% confidence interval 9.86-10.8), 1.61 (1.44-1.80), 1.44 (1.32-1.57), and 1.09 (1.02-1.18); when AIS at day 0 excluded in the risk periods, the corresponding IRRs were 1.77 (1.57-2.01) (day 1-3), 1.60 (1.43-1.79), 1.43 (1.31-1.56), and 1.09 (1.01-1.17), respectively. The association appeared to be stronger among younger beneficiaries and among beneficiaries without prior history of stroke but largely consistent across sex and race/ethnicities. DISCUSSION Risk of AIS among Medicare FFS beneficiaries was ten times (day 0 cases in the risk period) as high during the first 3 days after diagnosis of COVID-19 as during the control period and the risk associated with COVID-19 appeared to be stronger among those aged 65-74 years and those without prior history of stroke. CLASSIFICATION OF EVIDENCE This study provides Class IV evidence that SARS-CoV-2 infection, the virus that causes COVID-19, is associated with increased risk of AIS in the first three days after diagnosis in Medicare FFS beneficiaries ≥ 65 years age.

Abstract
BACKGROUND AND PURPOSE In the era of easily available antibiotic use, this study provides epidemiological evidence for a re-examination of the relationship between syphilis and IS. METHODS Patients aged 18 years and older with newly diagnosed syphilis were included (N=1,585) from 2000, to 2012, and participants without syphilis in the control group (N=6,340) were matched by propensity score (age, sex, index year, insured amount, urbanization, seasons, and comorbidities). The Cox proportional hazard model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of IS. Five different Cox regression models, sensitivity analyses, and negative control were conducted to test our findings. RESULTS 1,585 patients (1,055 [66.56%] men; mean [SD] age, 49.59 [20.32] years) had syphilis, and 3.8% had new-onset IS. The syphilis group had a higher risk of IS than the controls (adjusted HR, 1.35; 95% CI, 1.01-1.80; P-value<0.05) after full adjustment. Serial sensitivity analyses yielded consistent results. CONCLUSIONS Syphilis patients have higher risk of IS, and our data raise the question of implementation of prophylactic treatment for IS.

Abstract
Stroke is one of the primary causes of mortality and morbidity worldwide. It can be ischemic or hemorrhagic, and the former can be due to an in-situ thrombus or a distant embolus. Despite being a rare cause, stroke can also be caused in the setting of infection. Bacterial agents are the most common cause of stroke, among other infectious agents. Until the antibiotic era, rheumatic heart disease was a predisposing risk factor of infective endocarditis. VZV is the most common cause of strokes in pediatric and adult populations. Cryptococcus and Candida spp are the most common yeasts involved in CNS infections, especially in immunocompromised patients. In COVID-19 patients, ischemic strokes are more common than hemorrhagic strokes. In this review, we will discuss the most common infectious agents, with particular emphasis on COVID-19.

Abstract
PURPOSE OF THE REVIEW Inflammation is a key component in the pathogenesis of cerebrovascular diseases. In the past few years, the role of systemic infection and gut dysbiosis in modulating inflammation and stroke risk has been increasingly acknowledged. In this review, we synthesize contemporary literature on the effects of infection and inflammation on stroke risk and outcomes, with a focus on periodontal disease, COVID-19 infection, and gut dysbiosis. RECENT FINDINGS Chronic and acute infections such as periodontitis and COVID-19 induce systemic inflammation that cause atherogenesis and increase cardiac injury and arrhythmias. These infections also directly injure the endothelium leading to worsened secondary inflammation after stroke. Gut dysbiosis engenders a pro-inflammatory state by modulating intestinal lymphocyte populations that can traffic directly to the brain. Additionally, post-stroke immune dysregulation creates a compounding feedback loop of further infections and gut dysbiosis that worsen outcomes. Recent advances in understanding the pathophysiology of how infection and dysbiosis affect the progression of stroke, as well as long-term recovery, have revealed tantalizing glimpses at potential therapeutic targets. We discuss the multidirectional relationship between stroke, infection, and gut dysbiosis, and identify areas for future research to further explore therapeutic opportunities.

Abstract
BACKGROUND Cerebrovascular complications after adult-onset varicella-zoster virus (VZV) encephalitis have been increasingly recognized. The aim of this study was to analyze clinical and neuroimaging findings, treatment and outcome of these patients. METHODS Literature review from January 2000 to December 2019. We searched for studies published in PubMed, Embase and Chinese Biomedical Literature Database. Clinical symptoms, neuroimaging findings, treatment and outcome were evaluated. RESULTS We analyzed 31 articles with a total of adult-onset 34 cases, including 25 cases of ischemic stroke, 6 of intracerebral hemorrhage and 3 with venous sinus thrombosis. Ischemic stroke was the major complication after VZV encephalitis accounting of 73.35%. There were more males than females in ischemia or venous sinus thrombosis groups. The middle-aged was prone to cerebral infarction, the elderly was for cerebral hemorrhage, and the young was for venous sinus thrombosis. Cognitive impairment was the most common symptom either in the ischemic group or hemorrhagic group. The lesions of VZV-associated cerebral infarction or hemorrhage were multifocal and mostly involved in the parietal lobe, followed by frontal or temporal lobes. Venous sinus thrombosis was common in the transverse sinus. Multiple stenosis of the anterior and posterior circulation vessels was found. A 60.87% of the patients with antiviral treatment in the ischemic group had favorable prognosis. All patients with anticoagulant therapy in venous sinus thrombosis group improved well; however, 60% of the patients with intracerebral hemorrhage had a poor prognosis or died. CONCLUSION Ischemic stroke was the majority of cerebrovascular complications after VZV encephalitis, which mainly occurred in middle-aged men. The lesions of VZV-associated cerebral infarction or hemorrhage were multifocal and did not accord with the characteristics of cerebrovascular diseases induced by atherosclerosis. The patients with venous sinus thrombosis had a relatively good prognosis. When the patient represents with some neurological symptoms about one month after VZV encephalitis, and multiple lesions probably induced by vasculitis are showed in neuroimaging, cerebrovascular complications related to VZV infection should be considered.

Abstract
Infection plays a complex role in cerebrovascular disease and is believed to have both direct and indirect mechanisms on stroke pathogenesis. if not diagnosed and treated promptly, this may have devastating consequences. Management of infection-related strokes focuses on the treatment of the underlying infection with appropriate antimicrobial drugs and the prevention of medical complications. This can lead to devastating neurological deficits. We present two cases of cryptococcal meningoencephalitis that presented with an atypical cerebral infarction. A 55-year-old male with a history of unknown autoimmune disease presented with acute onset cognitive changes and no stroke-like symptoms. A 35-year-old male with no history of autoimmune disease or other existing immunodeficiency presented with breakthrough seizure a long with stroke-like symptoms. Both patients developed multiple cerebral infarcts in multiple vascular territories, with histologic and radiologic findings consistent with a central nervous system cryptococcosis. They were subsequently diagnosed with cryptococcal meningoencephalitis and started on the appropriate anti-fungal regimen with amphotericin B and flucytosine. Prior to discharge to an inpatient rehabilitation facility, both patients were notably improved and near their neurologic baseline. It is important to understand the pathogenesis of cryptococcal infection in the central nervous system because it produces a wide variety of clinico-radiographic features that can be overlooked. Clinicians should keep infection-mediated cerebral infarcts in mind, regardless of risk factors, in order to expedite antimicrobial therapy and minimize adverse events.

Abstract
This scoping review mapped out the relevant literature, identified gaps and made suggestions on the subject of the health needs of family caregivers (FC) of elderly stroke survivors (ESS). The authors utilised the PRISMA-ScR checklist to guide the scoping review. The databases PubMed, Elsevier and BioMed Central were searched for academic articles published in the English Language between the years 2010 and 2020 that met a pre-set criteria of content on the health needs of FC of ESS. The process of selection of sources of evidence based on screening and eligibility of evidence reduced the initially identified 13,303 sources of evidence in the searched databases to five sources of evidence. The content of these five sources of evidence was mapped out on a charting table where data was summarised and synthesised first individually and then collectively by the authors. Repetitive and irrelevant data were removed collectively by the authors from the charting table. The gaps identified were a paucity of research on the subject of health needs of FC of ESS, lack of longitudinal and mixed-methods research on the health needs of FC of ESS, sparse use of social sciences perspectives and theories, research that addresses specific physical and mental health concerns beyond general descriptions and gaps in information, social networks, interventions, health policy and systems. Future research directions were suggested and a limitation of this scoping review are addressed in the discussion.

Abstract
Tuberculous meningitis (TBM) has a variety of clinical manifestations and complications, and ischemic stroke is a common complication of TBM. However, there is no established prevention or treatment for stroke associated with TBM, and the safety and efficiency of thrombolysis in acute stroke caused by TBM remain unknown. Herein, we present a case of successful intravenous thrombolysis in ischemic stroke caused by TBM. A 50-year-old male patient with cerebral infarction had substantially improved neurological function after intravenous thrombolysis, and he was subsequently found to have TBM. Our findings suggest that intravenous thrombolysis might be an effective acute treatment method for infectious stroke.

Abstract
Background: The aim of the study was to assess the relevance of chronic rhinosinusitis (CRS) CT features to the efficacy of mechanical thrombectomy (MT) in patients with acute ischemic stroke. Methods: This study included 311 patients qualified for MT in whom the CRS features were assessed based on a CT scan, according to the Lund-Mackay (L-M) score. Clinical, inflammatory parameters, patients neurological (NIHSS) and functional status (mRS), and recanalisation efficacy (TICI) were compared between patients with mild lesions (L-M score 0–3 points)-group 1, and patients with more severe lesions (L–M score 4–24)-group 2. Results: There was a significant difference in the NIHSS on day seven after stroke onset-10 points in group 1 and 14 points in group 2, p = 0.02. NIHSS ≤ 6 points on day seven was found in 41.9% of patients in group 1, and in 27.5% in group 2, p = 0.042. There were no significant differences in mRS score and in the TICI score. L-M score, lipid abnormalities and CRP were factors associated with NIHSS ≥ 7 points on day 7. Conclusions: The CT features of CRS may be used as a prognostic tool for early prognosis assessment in stroke patients.

Abstract
INTRODUCTION The change of stroke incidence during the COVID-19 pandemic period and the proposed mechanisms of the relationship between SARS-CoV-2 and stroke is reviewed. METHODS Web of Science, PMC/Medline, and Scopus databases were searched until July 2020 without time and language limitations. After quality assessment, 22 articles were included in this study. RESULTS Based on the results, it is impossible to conclude any definite relationship between the rising or decreasing stroke frequency or the shift in the ischemic and hemorrhagic ratio and SARS-CoV-2 infection. However, it appears that SARS-CoV-2 infection has some correlation with stroke. The supposed mechanisms for the SARS-CoV-2-related hemorrhagic stroke include 1) SARS-CoV-2-related vasculopathy with the endothelial damage of small vessels, 2) viral infection-induced platelet dysfunction or thrombocytopenia, and 3) activation of the proinflammatory cascade leading to coagulopathy. The helpful strategies are receiving therapeutic anticoagulation for high D-dimer or a known thrombus due to SARS-CoV-2 infection, as well as using extracorporeal membrane oxygenation (ECMO) in some patients. Furthermore, the possible mechanisms for the SARS-CoV-2-related ischemic stroke include 1) dysregulation of angiotensin-converting enzyme 2 (a key host cellular receptor for SARSCoV-2)-related physiologic functions, 2) endothelial cell damages, 3) thrombo-inflammation, and 4) coagulopathy and coagulation abnormalities related to SARS-CoV-2 infection. CONCLUSION A better understanding of the SARS-CoV-2 pathogenesis and its relation to neurologic abnormalities such as stroke can help to design new therapeutic approaches.

Abstract
Purpose Central nervous system (CNS) bacterial and fungal infections can cause secondary vasculitis which worsens the prognosis due to development of complications like infarctions or hemorrhages. In this prospective study, we aim to study intracranial vessel wall imaging findings in bacterial and fungal infections. Methods We included 12 cases of nontubercular bacterial and fungal CNS infections each, in whom definitive microbiological diagnosis could be made. High-resolution vessel wall imaging (VWI) and time of flight MR angiography (TOF MRA) were incorporated in the routine imaging protocol. All cases were evaluated for the presence of vascular enhancement, pattern of enhancement, and stenosis on VWI. Statistical analysis was done to evaluate association between findings of vessel wall imaging and infarctions. Results We found infarctions in 5 out of 12 cases (41.7%) of the bacterial group and 7 out of 12 cases (58.3%) of the fungal group. Vessel wall enhancement was seen in 5 cases (41.7%) of the bacterial group and 9 cases (75%) of the fungal group. There was a significant association between infarctions and vessel wall enhancement in the fungal group. However, pattern of enhancement or stenosis on VWI was not significantly associated with presence of infarction. VWI detected more cases of vascular involvement than TOF MRA. Conclusion Secondary infectious vasculitis in bacterial and fungal infections can be detected by VWI, which can play an important role in better patient management as detection of vascular involvement can prompt early treatment to prevent complications like infarctions or hemorrhages.

Abstract
Introduction: A major cause of injury and the second cause of death worldwide is stroke. Among several infectious agents considered as the risk factor of stroke, some pathogens demonstrated stronger robust associations with stroke. Proposing an accurate correlation between infectious microorganisms and stroke provides valuable information for early intervention and control of the infections. Methods: In this study, we searched the literature using the Web of Science, PMC/Medline via PubMed, and Scopus databases up to July 2018 without time and language restrictions. After quality assessment, 16 articles were included in the study. The whole data extraction process was independently conducted by two reviewers. Results: Based on the results of the studies, viruses, such as Hepatitis C virus (HCV), Hepatitis B virus (HBV), Human Immunodeficiency Virus (HIV), Herpes Simplex Virus Type-1, 2 (HSV-1, 2), Varicella-Zoster Virus (VZV or Chickenpox), and West Nile virus (WNV) seem to be common causes of ischemic stroke. Moreover, the association of other microbial categories, such as Streptococcus mutans (in bacteria), Toxocara spp. and Toxoplasma gondii (in parasites), and Rhizopus sp. (in fungi) with stroke was reported. Conclusion: Considering the adverse role of the above-mentioned microorganisms, it is necessary to implement some preventive measures for stroke treatment.

Abstract
Aim/Background This review investigated a patient with Alzheimer's disease (AD) treated with 4,4′-diaminodiphenyl sulfone (DDS) as a neuroinflammasome competitor. Methods We monitored AD's progression through numeric clinical staging (NCS) with a new biomarker. NCS was determined by the presence of AD symptoms and neuropsychiatric (NP) symptoms caused by anti-AD (AAD) drugs (D) as a biomarker. We also monitored the function of DDS for stroke in a no-intake emergency state. Results By introducing (D), AD's progression was monitored through NCS staging. AAD side effects and neuropsychiatric symptoms were identified. DDS was stopped in patients with stroke with NCS 6 caused by AAD, and it rapidly proceeded to cerebral infarct. Conclusions AAD can occasionally exacerbate AD and stroke. DDS can alleviate mild cognitive impairment (MCI), early AD and stroke. We clinically confirmed the role of DDS as a neuroinflammasome competitor after stroke. DDS preserved neuronal survival within 24–55 h in the Seoul Study cohort.

Abstract
The severe acute respiratory syndrome coronavirus 2 or coronavirus disease 2019 (COVID-19) pandemic has raised concerns about the correlation with this viral illness and increased risk of stroke. Although it is too early in the pandemic to know the strength of the association between COVID-19 and stroke, it is an opportune time to review the relationship between acute viral illnesses and stroke. Here, we summarize pathophysiological principles and available literature to guide understanding of how viruses may contribute to ischemic stroke. After a review of inflammatory mechanisms, we summarize relevant pathophysiological principles of vasculopathy, hypercoagulability, and hemodynamic instability. We will end by discussing mechanisms by which several well-known viruses may cause stroke in an effort to inform our understanding of the relationship between COVID-19 and stroke.

Abstract
Stroke is the second leading cause of death globally. Despite the decreasing trend in stroke mortality, its incidence and prevalence follow an upwards trajectory that is envisaged to continue for years to come. Previous literature has suggested a role for infectious disease in stroke aetiology; however, the pathophysiological basis for this has never fully been understood. Emerging infections, such as coronavirus disease (COVID-19), present new challenges that must be addressed, to prevent them from contributing to the predicted rise in stroke incidence. Almost one in 20 patients diagnosed with COVID-19 experience a stroke thereafter, hence achieving better understanding of the interactions between these disease entities is of major clinical significance.

Abstract
Coronavirus disease 2019 (COVID-19) is caused by the novel coronavirus severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Systemic complications include cardiovascular, neurological, hepatic, renal and altered coagulation. Derangements in haemostasis with SARS-CoV-2 infection have been termed COVID-19 associated coagulopathy (CAC). CAC is postulated to be one of the significant causes for sudden deaths in this pandemic, with infection of endothelial cells and subsequent endotheliitis through angiotensin-converting enzyme-2 receptors playing a key role in the pathogenesis. In this pictorial review, we describe the imaging findings in a multitude of extrapulmonary arterial (aorta, cerebral, mesenteric, renal and peripheral arterial system) and venous thrombotic phenomena detected on contrast-enhanced computed tomography and magnetic resonance imaging of COVID-19 patients which could not be attributed to any other causes. Knowledge of incidence of these complications, lowering the threshold for diagnostic imaging in symptomatic patients and timely radiological detection can play a vital role in subsequent management of these critically ill patients.

Abstract
BACKGROUND AND PURPOSE Preceding infection as an important risk factor for ischemic stroke has been reported but neglected for hemorrhagic stroke, especially in young and middle-aged patients. This study investigates whether newly diagnosed leptospirosis is associated with an increased risk of stroke. METHODS We identified 3699 in-patients who were aged ≥18 years and newly diagnosed with leptospirosis. We also randomly selected a comparison cohort 14 796 in-patients from the general population by using a propensity score matching method (at a 1:4 ratio). We analyzed the risks of stroke by using Cox proportional hazard regression models. RESULTS The adjusted hazard ratio (HR; 95% CI) of stroke for the leptospirosis group was 1.14 (0.93-1.38; P=0.200) as opposed to the comparison group after adjusting sex, age, and comorbidities. However, adjusted HR (95% CI) of ischemic stroke and hemorrhagic stroke was 1.01 (0.80-1.29) and 1.58 (1.12-2.23), respectively. The strength of association between leptospirosis and hemorrhagic stroke remained statistically significant after variation of leptospirosis and stroke definitions. The post hoc subgroup analysis indicated that a patient with leptospirosis had a significantly greater risk of hemorrhagic stroke in male (adjusted HR, 1.62 [95% CI, 1.08-2.44]) and individuals between age 18 and 39 (adjusted HR, 3.67 [95% CI, 1.33-10.14]). The risk of hemorrhagic stroke among people with leptospirosis was highest in the first 2 years after diagnosis (adjusted HR, 1.97 [95% CI, 1.15-3.38]). CONCLUSIONS A 2.49-fold risk of stroke was found among the leptospirosis cohort of aged younger than 39 years. Age acted as an effect modifier between the leptospirosis and risk of new-onset stroke.

Abstract
OBJECTIVE Cerebral microbleeds (CMBs) is a subtype of cerebral small vessel disease. Their underlying pathogenesis remains unclear. The aim of this study was to investigate the association between infectious burden (IB) and CMBs. METHODS Seven hundred and seventy-three consecutive patients who were hospitalized in the Department of Neurology in General Hospital of Western Theater Command without severe neurological symptoms were recruited and selected in this pilot cross-sectional study. CMBs were assessed using the susceptibility-weighted imaging sequence of magnetic resonance imaging. Immunoglobulin G antibodies against common pathogens, including herpes simplex virus (HSV)-1, HSV-2, cytomegalovirus (CMV), Chlamydia pneumoniae (C. pneumoniae), Mycoplasma pneumoniae (M. pneumoniae), Epstein-Barr virus (EBV), Helicobacter pylori (HP), and Borrelia burgdorferi (B. burgdorferi), were measured by commercial ELISA assays. IB was defined as a composite serologic measure of exposure to these common pathogens. RESULTS Patients with and without CMBs were defined as the CMBs group (n = 76) and the non-CMBs group (n = 81), respectively. IB was significantly different between the CMBs and non-CMBs groups. After adjusted for other risk factors, the increased IB was independently associated with the presence of CMBs (P = 0.031, OR = 3.00, 95% CI [1.11-8.15]). IB was significantly positively associated with the number of CMBs (Spearman ρ = 0.653, P < 0.001). The levels of serum inflammatory markers were significantly different between the CMBs and non-CMBs groups and among the categories of IB. INTERPRETATION IB consisting of HSV-1, HSV-2, CMV, C. pneumoniae, M. pneumoniae, EBV, HP, and B. burgdorferi was associated with CMBs. All the findings suggested that pathogen infection could be involved in the pathogenesis of CMBs.

Abstract
Gut microbiota is closely associated with the occurrence of neuropsychiatric disorders. Antibiotics are frequently used to prevent pathogen infection in patients with brain ischemia. To understand the impact of prophylactic antibiotic treatment for patients with brain ischemia, we examined the effects of orally administered vancomycin and ampicillin on cognitive function and gut microbiota composition in mice with transient global forebrain ischemia (tIsc). tIsc operation and orally gavaged vancomycin mildly and moderately caused cognitive impairment, respectively. However, the exposure of mice with tIsc to vancomycin or ampicillin severely impaired cognitive function in the Y-maze, novel object recognition, and Banes maze tasks. Furthermore, their treatments induced NF-κB activation as well as active microglia (NF-κB+/Iba1+ and LPS+/Iba1+ cells) and apoptotic (caspase 3+/NeuN+) cell population in the hippocampus, whereas the brain-derived neurotrophic factor (BDNF)+/NeuN+ cell populations decreased. These treatments also caused colitis and gut dysbiosis. They increased the population of Proteobacteria including Enterobacter xiangfangenesis. Orally delivered fecal transplantation of vancomycin-treated mice with or without tIsc and oral gavage of Enterobacter xiangfangenesis also significantly deteriorated the cognitive impairment and colitis in transplanted mice with tIsc. These findings suggest that oral administration of antibiotics can deteriorate cognitive impairment with gut dysbiosis in patients with brain ischemia.

Abstract
OBJECTIVE This study comprehensively estimated the excess cardiovascular disease (CVD) mortality attributable to influenza in an older (age ≥65 years) population. DESIGN Ecological study. SETTING Aggregated data from administrative systems on CVD mortality, influenza surveillance and meteorological data in Beijing, China. MAIN OUTCOME MEASURE Excess overall CVD, and separately for ischaemic heart disease (IHD), ischaemic stroke, haemorrhagic stroke mortality attributable to influenza, adjusting for influenza activity, time trend, seasonality and ambient temperature. RESULTS CVD (risk ratio (RR) 1.02, 95% CI 1.01, 1.02), IHD (RR 1.01, 95% CI 1.01, 1.02), ischaemic stroke (RR=1.03, 95% CI 1.02, 1.04), but not haemorrhagic stroke (RR=1.00, 95% CI 0.99, 1.01) mortality, were significantly associated with every 10% increase in influenza activity. An increase in circulating A(H1N1)09pdm, A(H3N2) and B type virus were all significantly associated with CVD and ischaemic stroke mortality, but only A(H3N2) and B type virus with IHD mortality. The strongest increase in disease mortality was in the same week as the increase in influenza activity. Annual excess CVD mortality rate attributable to influenza ranged from 54 to 96 per 100 000 population. The 3%-6% CVD mortality attributable to influenza activity was related to an annual excess of 916-1640 CVD deaths in Beijing, China. CONCLUSIONS Influenza activity has moderate to strong associations with CVD, IHD and ischaemic stroke mortality in older adults in China. Promoting influenza vaccination could have major health benefit in this population. BACKGROUND Influenza may trigger serious CVD events. An estimation of excess CVD mortality attributable to influenza has particular relevance in China where vaccination is low and CVD burden is high. METHODS This study analysed data at the population level (age ≥65 years) using linked aggregated data from administrative systems on CVD mortality, influenza surveillance and meteorological data during 2011 to 2018. Quasi-Poisson regression models were used to estimate the excess overall CVD, and separately for IHD, ischaemic stroke, haemorrhagic stroke mortality attributable to influenza, adjusting for influenza activity, time trend, seasonality and ambient temperature. Analyses were also undertaken for influenza subtypes (A(H1N1)09pdm, A(H3N2) and B viruses), and mortality risk with time lags of 1-5 weeks following influenza activity in the current week.

Neurologic Injury in Patients Treated With Extracorporeal Membrane Oxygenation for Postcardiotomy Cardiogenic Shock. J Cardiothorac Vasc Anesth 2020; 35:2669-2680. [PMID: 33262035 DOI: 10.1053/j.jvca.2020.11.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2020] [Revised: 11/01/2020] [Accepted: 11/02/2020] [Indexed: 11/11/2022]
Abstract
OBJECTIVE To investigate the frequency, predictors, and outcomes of neurologic injury in adults treated with postcardiotomy extracorporeal membrane oxygenation (PC-ECMO). DESIGN A retrospective multicenter registry study. SETTING Twenty-one European institutions where cardiac surgery is performed. PARTICIPANTS A total of 781 adult patients who required PC-ECMO during 2010 to 2018 were divided into patients with neurologic injury (NI) and patients without neurologic injury (NNI). MEASUREMENTS AND MAIN RESULTS Baseline and operative data, in-hospital outcomes, and long-term survival were compared between the NI and the NNI groups. Predictors of neurologic injury were identified. A subgroup analysis according to the type of neurologic injury was performed. Overall, NI occurred in 19% of patients in the overall series, but the proportion of patients with NI ranged from 0% to 65% among the centers. Ischemic stroke occurred in 84 patients and hemorrhagic stroke in 47 patients. Emergency procedure was the sole independent predictor of NI. In-hospital mortality was higher in the NI group than in the NNI group (79% v 61%, p < 0.001). The one-year survival was lower in the NI group (17%) compared with the NNI group (37%). Long-term survival did not differ between patients with ischemic stroke and those with hemorrhagic stroke. CONCLUSION Neurologic injury during PC-ECMO is common and associated with a dismal prognosis. There is considerable interinstitutional variation in the proportion of neurologic injury in PC-ECMO-treated adults. Well-known risk factors for stroke are not associated with neurologic injury in this setting.

Abstract
Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is the third leading cause of cardiovascular death in the world. Important risk factors of thrombosis include bed restraint, surgery, major trauma, long journeys, inflammation, pregnancy, and oral contraceptives, previous venous thromboembolism, cancer, and bacterial infections. Sepsis increases the risk of blood clot formation 2–20 times. In this review, we discussed various mechanisms related to the role of bacteria in venous thrombosis also taking into consideration the role of the human microbiome. Many known bacteria, such as Helicobacter pylori, Chlamydia pneumoniae, Mycoplasma pneumoniae, Haemophilus influenzae, Streptococcus pneumoniae, Staphylococcus aureus, and Escherichia coli, causing infections may increase the risk of thrombotic complications through platelet activation or may lead to an inflammatory reaction involving the fibrinolytic system. Additionally, the bacteria participate in the production of factors causing or increasing the risk of cardiovascular diseases. An example can be trimethylamine N-oxide (TMAO) but also uremic toxins (indoxyl sulfate), short-chain fatty acids (SCFA) phytoestrogens, and bile acids. Finally, we presented the involvement of many bacteria in the development of venous thromboembolism and other cardiovascular diseases.
