Abstract
Introduction Acute ischemic stroke (AIS) and intracerebral hemorrhage (ICH) are among the acute cerebrovascular diseases (CVDs) that have been reported as a result of COVID-19. It will be a significant step forward if our research helps improve the compilation and analysis of existing data from other studies. Methods The study is registered on PROSPERO with an ID of CRD42023464058. It encompasses articles published until December 2023 and involves searching databases such as PubMed, Scopus, Web of Knowledge, Embase, and Cochrane. Additionally, we conducted manual searches in respected publications within this discipline, utilized the Google Scholar search engine, and conducted reference checks, citation checks, and study of gray literature. The publications' reporting quality was assessed using the "Assessment of Multiple Systematic Reviews" (AMSTAR) checklist. The meta-analysis was conducted using Stata software (StataCorp, version 16). Results We analyzed the findings of 23 meta-analyses, which included 795 articles and encompassed 5,937 patients who had previously experienced a stroke. The average age of these patients was 62.3 years, and 68.3% were male. The findings indicated that the collective incidence of stroke among individuals with COVID-19 is roughly 1.75% [95% confidence interval (CI): 0.4%-3.03], with 1.59% for ischemic strokes and 0.3% for hemorrhagic strokes. 32.3% (95% CI: 27.8%-36.9%) of COVID-19 patients with stroke passed away, approximately 27% were discharged from the hospital with very mild or no complications, and around 28.1% (95% CI: 14.1%-42.1%) were referred for rehabilitation. Conclusions The overall rate of stroke in COVID-19 patients was approximately 1.75%, with a higher incidence in males and those with an average age of 62.3 years. Almost 80% of the strokes were ischemic, and the mortality rate was approximately 32%. Finally, 27% of the patients were discharged without complications, and 28% required rehabilitation.

Ischaemic stroke in patients with diabetes requiring urgent procedures during the COVID-19 pandemic in South Korea: a retrospective, nationwide, population-based cohort study using data from the National Emergency Department Information System. BMJ Open 2023; 13:e074381. [PMID: 38097233 PMCID: PMC10729090 DOI: 10.1136/bmjopen-2023-074381] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Accepted: 11/24/2023] [Indexed: 12/18/2023] Open
Abstract
OBJECTIVES The COVID-19 pandemic resulted in suboptimal care for ischaemic stroke. Patients with diabetes mellitus (DM), a high-risk group for stroke, had compromised routine care during the pandemic, which increases the chance of stroke. We examined influence of the COVID-19 pandemic on the management of ischaemic stroke in patients with DM in South Korea. DESIGN Retrospective, nationwide, population-based cohort study. SETTING Data from the National Emergency Department Information System. PARTICIPANTS We analysed 11 734 patients diagnosed with acute ischaemic stroke who underwent intravenous thrombolysis or endovascular thrombectomy between 2019 (the reference year) and 2020 (the pandemic year). Among them, 1014 subjects with DM were analysed separately. OUTCOME MEASURES The frequency of emergency department (ED) visits, time from symptom onset to ED, from ED visit to admission and in-hospital mortality were compared between two periods in the overall population and in patients with DM. RESULTS During the pandemic, the incidence of ischaemic stroke requiring urgent procedures increased by 7.57% in total and by 9.03% in patients with DM. Time delay from symptom onset to ED (reference vs pandemic, total: 1.50 vs 1.55 hours; p<0.01) and from ED visit to admission (total: 3.88 vs 3.92 hours; p=0.02) occurred during the pandemic in the overall population, but not significantly in patients with DM specifically. Older patients with DM showed higher chances of intensive care unit (ICU) admission during the pandemic: 53.5% vs 62.8% in age 70-79, 60.5% vs 71.9% in age 80-89 and 20.0% vs 70.8% in age ≥90 years (all p=0.01). There was no significant difference in in-hospital mortality between two periods (total: 8.2% vs 8.4%, p=0.65; DM: 8.1% vs 6.7%, p=0.25). CONCLUSIONS During the COVID-19 pandemic, the incidence of ischaemic stroke requiring urgent procedures increased, and older patients with DM showed a higher ICU admission rate. However, the pandemic was not associated with an increased in-hospital stroke mortality.

Abstract
The Coronavirus disease 2019 (COVID-19) epidemic has triggered a huge impact on healthcare, socioeconomics, and other aspects of the world over the past three years. An increasing number of studies have identified a complex relationship between COVID-19 and stroke, although active measures are being implemented to prevent disease transmission. Severe COVID-19 may be associated with an increased risk of stroke and increase the rates of disability and mortality, posing a serious challenge to acute stroke diagnosis, treatment, and care. This review aims to provide an update on the influence of COVID-19 itself or vaccines on stroke, including arterial stroke (ischemic stroke and hemorrhagic stroke) and venous stroke (cerebral venous thrombosis). Additionally, the neurovascular mechanisms involved in SARS-CoV-2 infection and the clinical characteristics of stroke in the COVID-19 setting are presented. Evidence on vaccinations, potential therapeutic approaches, and effective strategies for stroke management has been highlighted.

Watershed infarction in COVID-19: The necessity of neuroimaging in patients with subtle neurological symptoms. CURRENT JOURNAL OF NEUROLOGY 2023; 22:170-178. [PMID: 38011454 PMCID: PMC10626137 DOI: 10.18502/cjn.v22i3.13797] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Accepted: 05/13/2023] [Indexed: 11/29/2023]
Abstract
Background: Cerebrovascular diseases comprise a significant portion of neurological disorders related to coronavirus disease 2019 (COVID-19). We evaluated the clinical and imaging characteristics of a cohort of COVID-19 patients with stroke and also identified patients with watershed infarcts. Methods: In this cross-sectional study, seventy-three COVID-19 patients with ischemic stroke were included between October 2020 and January 2021. Patients were evaluated based on the following clinical and imaging features: severity of COVID-19 (critical/ non-critical), stroke type, presence/absence of clinical suspicion of stroke, medical risk factors, Fazekas scale, atherothrombosis, small vessel disease, cardiac pathology, other causes, and dissection (ASCOD) criteria classification, and presence or absence of watershed infarction. Clinical outcomes were assessed based on Modified Rankin Scale (MRS) and mortality. Results: Most cases of ischemic stroke were due to undetermined etiology (52.1%) and cardioembolism (32.9%). In terms of imaging pattern, 17 (23.0%) patients had watershed infarction. Watershed infarction was associated with the clinically non-suspicious category [odds ratio (OR) = 4.67, P = 0.007] and death after discharge (OR = 7.1, P = 0.003). Patients with watershed infarction had a higher odds of having high Fazekas score (OR = 5.17, P = 0.007) which was also shown by the logistic regression model (adjusted OR = 6.87, P = 0.030). Thirty-one (42%) patients were clinically non-suspected for ischemic stroke. Critical COVID-19 was more common among patients with watershed infarct and clinically non-suspicious patients (P = 0.020 and P = 0.005, respectively). Patients with chronic kidney disease (CKD) were more prone to having stroke with watershed pattern (P = 0.020). Conclusion: Watershed infarct is one of the most common patterns of ischemic stroke in patients with COVID-19, for which clinicians should maintain a high index of suspicion in patients with critical COVID-19 without obvious clinical symptoms of stroke.

Abstract
Introduction The categorization system used in the Trial Org 10172 classification in Acute Stroke Treatment (TOAST) provided more insight into the causal process. The aims of this study were to characterize individuals with acute ischemic stroke using the TOAST criteria and to determine risk variables for patients with acute ischemic stroke during the COVID-19 pandemic. Methods A cross-sectional study was done on the medical records of acute ischemic stroke patients at Hasan Sadikin Hospital (RSHS) Bandung, Indonesia, who were hospitalized in the Neurology Department of Hasan Sadikin Hospital from January to December 2021. Eligible patients were divided into 2 groups, with and without COVID-19 infection. Results There were 136 participants with acute ischemic stroke. Thirty-one percent of strokes were caused by atherosclerosis in the large arteries (LAA), followed by small-vessel occlusion (SVO) (25%), cardioembolism (CE) (22.1%), an undetermined cause (21.3%), and an other etiology (1.5%). CE risk factor was atrial fibrillation (p < 0.001), while hypertension, diabetes, and smoking were significant for LAA (p < 0.05). However, in patients with COVID-19 who had an acute ischemic stroke, most of the subtypes were stroke of undetermined etiology (76%), and hypercoagulation was the main risk factor (p < 0.001). Conclusion Patients with and without COVID-19 show varied distributions of stroke subtypes according to the TOAST categorization. Hypercoagulation is a major risk factor for stroke of undetermined etiology in individuals with COVID-19 who suffer from acute ischemic stroke. Increased viral-mediated endothelial inflammation leading to aberrant coagulopathy may explain the correlation between COVID-19 and acute ischemic stroke.

Abstract
BACKGROUND Ischemic stroke associated with coronavirus 2019 (COVID-19) has been well recognized by now. Few studies have compared COVID related versus unrelated strokes. We intend to report on a large group of Asian patients from two countries and compare COVID with non-COVID strokes admitted during the same time period. METHODS Consecutive cases of acute ischemic stroke either presenting or developing, between March 2020 and December 2021 in four tertiary care hospitals (1 in Dubai, UAE and 3 in Karachi, Pakistan) and testing positive for COVID-19 were included in the study. Patients admitted with ischemic stroke during the same time period and who tested negative for COVID-19 were also randomly selected from the four hospitals. All data was collected from the medical records of the patients and recorded on a standard questionnaire before it was entered in SPSS version 21 for analysis. RESULTS There were 139 COVID positive and 271 COVID negative patients with acute ischemic stroke included in the current study. There were significantly more males (80.6% vs 64.9%, p=0.001) and more large vessel strokes in the COVID positive group (41% vs 21.8%, p<0.001). Being COVID positive was an independent predictor of poor outcome at discharge, defined as a modified Rankin score of 3-6 (OR 3.87, 95% CI 2.21-6.77) after adjusting for country, age, sex, vascular comorbid conditions and stroke subtype. CONCLUSIONS In this largest series of patients with COVID related strokes from Asia, COVID-19 was an independent predictor of poor outcomes at discharge after adjusting for other variables.

Abstract
INTRODUCTION The second wave of COVID-19 in Indonesia occurred due to delta variant transmission with up to 2266 cases. This variant could cause higher rate of morbidities and mortalities. This study reported coagulation profile of COVID-19 patients with acute stroke and its association with patients' outcome. METHOD This is a cohort-retrospective study conducted during the second wave of COVID-19, June-August 2021 in Cipto Mangunkusumo General Hospital. Inclusion criteria were adult patients with confirmed COVID-19 and diagnosed with acute stroke confirmed by radiological evidences. Exclusion criteria were COVID-19 patients with prior diagnosis of acute stroke. Coagulation factors were analyzed and presented with tables and graphs. RESULTS A total of 33 patients included in this study with majority experienced ischemic stroke (84.8%), followed by ischemic with haemorrhagic transformation (9.1%), and the rest with haemorrhagic stroke. The median of fibrinogen and D-dimer was 487.1(147-8,943)mg/dL and 2,110(250-35,200)ug/L respectively. Prothrombin time (PT) ratio was 0.95(0.82-1.3) and activated partial thromboplastin time (APTT) ratio was 1.01(0.64-2.72). On observation, 33.3% died during hospitalization, D-dimer value in these patients was significantly higher with 9,940ug/L compared to those who survived with 1,160ug/L(p = 0.009). The highest D-dimer value during hospitalization was also significantly higher with the median of 14,395ug/L compared to 3,740 ug/L (p = 0.014). DISCUSSION D-dimer value on initial assessment and its highest value during hospitalization were significantly higher in patient with poor outcome, showing that D-dimer can be one predictor of mortality in COVID-19 patients with acute stroke.

Abstract
Cerebrovascular diseases, such as ischemic stroke, pose serious medical challenges worldwide due to their high morbidity and mortality and limitations in clinical treatment strategies. Studies have shown that reactive oxygen species (ROS)-mediated inflammation, excitotoxicity, and programmed cell death of each neurovascular unit during post-stroke hypoxia and reperfusion play an important role in the pathological cascade. Ferroptosis, a programmed cell death characterized by iron-regulated accumulation of lipid peroxidation, is caused by abnormal metabolism of lipids, glutathione (GSH), and iron, and can accelerate acute central nervous system injury. Recent studies have gradually uncovered the pathological process of ferroptosis in the neurovascular unit of acute stroke. Some drugs such as iron chelators, ferrostatin-1 (Fer-1) and liproxstatin-1 (Lip-1) can protect nerves after neurovascular unit injury in acute stroke by inhibiting ferroptosis. In addition, combined with our previous studies on ferroptosis mediated by natural compounds in ischemic stroke, this review summarized the progress in the regulation mechanism of natural chemical components and herbal chemical components on ferroptosis in recent years, in order to provide reference information for future research on ferroptosis and lead compounds for the development of ferroptosis inhibitors.

Abstract
As of May 2022, there have been more than 400 million cases (including re-infections) of the systemic acute respiratory syndrome-coronavirus 2 (SARS-CoV-2), and nearly 5 million deaths worldwide. Not only has the coronavirus disease 2019 (COVID-19) pandemic been responsible for diagnosis and treatment delays of a wide variety of conditions, and overwhelmed the allocation of healthcare resources, it has impacted the epidemiology and management of cerebrovascular disease. In this narrative review, we summarize the changing paradigms and latest data regarding the complex relationship between COVID-19 and cerebrovascular disease. Paradoxically, although SARS-CoV-2 has been associated with many thrombotic complications—including ischemic stroke—there have been global declines in ischemic stroke and other cerebrovascular diseases. These epidemiologic shifts may be attributed to patient avoidance of healthcare institutions due to fear of contracting the novel human coronavirus, and also related to declines in other transmissible infectious illnesses which may trigger ischemic stroke. Despite the association between SARS-CoV-2 and thrombotic events, there are inconsistent data regarding targeted antithrombotics to prevent venous and arterial events. In addition, we provide recommendations for the conduct of stroke research and clinical trial planning during the ongoing COVID-19 pandemic, and for future healthcare crises.

Abstract
Background: Neurological manifestations of coronavirus disease 2019 (COVID-19) have been highlighted. COVID-19 potentially increases the risk of thromboembolism. We aimed to compare patients with COVID-19 with and without new-onset acute ischemic stroke (AIS). Materials and Methods In this single-center retrospective case–control study, demographics, clinical characteristics, laboratory findings, and clinical outcomes were compared between 51 patients with both COVID-19 and AIS (group A) and 160 patients with COVID-19 and without AIS (group B). Results: Patients in group A were significantly older, more likely to present with critical COVID-19 (P = 0.004), had higher rates of admission in the intensive care unit (P < 0.001), more duration of hospitalization (P < 0.001), and higher in-hospital mortality (P < 0.001). At the time of hospitalization, O2 saturation (P = 0.011), PH (P = 0.04), and HCO3 (P = 0.005) were lower in group A. White blood cell count (P = 0.002), neutrophil count (P < 0.001), neutrophil-lymphocyte ratio (P = 0.001), D-Dimer (P < 0.001), blood urea nitrogen (BUN) (P < 0.001), and BUN/Cr ratio (P < 0.001) were significantly higher in patients with AIS. Conclusion: Stroke in COVID-19 is multifactorial. In addition to conventional risk factors of ischemic stroke (age and cardiovascular risk factors), we found that patients with more severe COVID-19 are more prone to ischemic stroke. Furthermore, leukocyte count, neutrophil count, neutrophil-lymphocyte ratio, D-Dimer, BUN, and BUN/Cr ratio were higher in patients with AIS following COVID-19 infection.

Abstract
Stroke is a fatal morbidity that needs emergency medical admission and immediate medical attention. COVID-19 ischemic brain damage is closely associated with common neurological symptoms, which are extremely difficult to treat medically, and risk factors. We performed literature research about COVID-19 and ischemia in PubMed, MEDLINE, and Scopus for this current narrative review. We discovered parallel manifestations of SARS-CoV-19 infection and brain ischemia risk factors. In published papers, we discovered a similar but complex pathophysiology of SARS-CoV-2 infection and stroke pathology. A patient with other systemic co-morbidities, such as diabetes, hypertension, or any respiratory disease, has a fatal combination in intensive care management when infected with SARS-CoV-19. Furthermore, due to their shared risk factors, COVID-19 and stroke are a lethal combination for medical management to treat. In this review, we discuss shared pathophysiology, adjuvant risk factors, challenges, and advancements in stroke-associated COVID-19 therapeutics.

Abstract
Background and Purpose To investigate the effect of prior ischemic stroke on the outcomes of patients hospitalized with coronavirus disease 2019 (COVID-19), and to describe the incidence, clinical features, and risk factors of acute ischemic stroke (AIS) following COVID-19. Methods In this population-based retrospective study, we included all the hospitalized positive patients with COVID-19 at Wuhan City from December 29, 2019 to April 15, 2020. Clinical data were extracted from administrative datasets coordinated by the Wuhan Health Commission. The propensity score matching and multivariate logistic regression analyses were used to adjust the confounding factors. Results There are 36,358 patients in the final cohort, in which 1,160 (3.2%) had a prior stroke. After adjusting for available baseline characteristics, patients with prior stroke had a higher proportion of severe and critical illness and mortality. We found for the first time that the premorbid modified Rankin Scale (MRS) grouping (odds ratio [OR] = 1.796 [95% CI 1.334–2.435], p < 0.001) and older age (OR = 1.905 [95% CI 1.211–3.046], p = 0.006) imparted increased risk of death. AIS following COVID-19 occurred in 124 (0.34%) cases, and patients with prior stroke had a much higher incidence of AIS (3.4%). Logistic regression analyses confirmed an association between the severity of COVID-19 with the incidence of AIS. COVID-19 patients with AIS had a significantly higher mortality compared with COVID-19 patients without stroke and AIS patients without COVID-19. Conclusions Coronavirus disease 2019 patients with prior stroke, especially those with the higher premorbid MRS or aged, have worse clinical outcomes. Furthermore, COVID-19 increases the incidence of AIS, and the incidence is positively associated with the severity of COVID-19.

Abstract
Introduction Although neurologic involvement and neuroimaging abnormalities have been frequently identified in COVID-19 patients, the underlying factors remain unclear. In this study, we assessed the association of the neurological manifestations and neuroimaging features of hospitalized COVID-19 patients with their clinical, laboratory, and imaging characteristics. Methods This multicenter cross-sectional study was conducted between September 2020 and March 2021 at two large academic hospitals in Tehran, Iran. We used census sampling from medical records to enroll hospitalized patients with a positive COVID-19 Polymerase chain reaction (PCR) test who underwent brain imaging due to presenting any acute neurologic symptom during hospital stay. Results Of the 4372 hospitalized patients with COVID-19, only 211 met the inclusion criteria (35.5% with severe infection). Central nervous system and psychiatric manifestations were significantly more common in severe cases (p ≤ 0.044). Approximately, 30% had a new abnormality on their neuroimaging, with ischemic (38/63) and hemorrhagic (16/63) insults being the most common. The most frequent reasons that provoked cranial imaging were headache (27%), altered consciousness (25.6%), focal neurologic signs (19.9%), and delirium (18%). Analysis revealed a positive correlation for age, neutrophilia, lymphopenia, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) with the emergence of neuroimaging abnormalities (p ≤ 0.018). In addition, patients with new neuroimaging abnormalities had a significantly higher lung CT score than those without any pathologic findings (11.1 ± 4.8 vs. 5.9 ± 4.8, p < 0.001). Conclusion Approximately 30% of the study population had various acute neuroimaging findings. The lung CT score, neutrophil count, and age were strong predictors of acute neuroimaging abnormalities in hospitalized COVID-19 patients.

Abstract
This study was conducted to determine the prevalence of prolonged neuromuscular symptoms, including fatigue, anosmia, headache, myalgia, and joint pain in COVID-19 survivors hospitalized with mild, moderate, or severe infections worldwide. The search was conducted up to January 30th, 2021 using three databases (PubMed, Scopus, and Web of Science) to identify potentially eligible studies. Data on study characteristics, follow-up characteristics, and severity of COVID-19 during hospitalization were collected in accordance with PRISMA guidelines. The Newcastle-Ottawa scale was used to assess the quality of relevant articles. The estimated prevalence of specific prolonged neuromuscular symptoms and the association between COVID-19 severity and occurrence of prolonged neuromuscular symptoms was analyzed wherever appropriate. Database search yielded 4,050 articles and 22 articles were included for meta-analysis. The estimated prevalence of prolonged fatigue was recorded in 21.2% (95%CI: 11.9%- 34.8%) of 3,730 COVID-19 survivors. Persistent anosmia was recorded in 239 of 2,600 COVID-19 survivors (9.7%, 95%CI: 6.1%-15.2%). In 84 out of 2,412 COVID-19 survivors (8.9%, 95%CI: 3.2%-22.6%), prolonged headache was observed. A total of 53 out of 1,125 COVID-19 patients (5.6%, 95%CI: 2.1%-14.2%) complained of persistent myalgia even after being discharged from the hospital. The prevalence of prolonged joint pain was in 15.4% (95%CI: 8.2%-27.2%) of subjects. Due to data scarcity on COVID-19 severity and prolonged neuromuscular symptoms, association analysis could not be conducted. Widespread concern regarding long-term impacts of COVID-19 was raised after several studies reported prolonged symptoms in COVID-19 survivors. Numerous theories have been proposed to address this concern; however, as the research on this pandemic is still ongoing, no explanation is definitive yet. Therefore, follow-up studies in COVID-19 survivors after recovery from COVID-19 are warranted to determine the pathogenesis of prolonged symptoms. PROSPERO registration: CRD42021242332.

Abstract
BACKGROUND Neurological involvements of COVID-19 are one of the most reported manifestations of this infection. This study aims to systematically review the previous systematic reviews which addressed the neurological manifestations of the COVID-19 infection. METHODS Following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, a comprehensive search was conducted in PubMed, Embase, Scopus, Web of Science databases and Google Scholar from December 2019 to December 2020. Articles were critically screened by two independent reviewers and if met the inclusion criteria, entered the study. Assessment of methodological quality was conducted by Assessment of Multiple Systematic Reviews-2 (AMSTAR-2) tool. Statistical analysis was not applicable. From a total of 1302 studies, 308 studies were removed due to their irrelevant title and abstract. After screening the full texts, a total of 66 found to be eligible. Twenty-one studies reported general manifestations of the COVID-19, 13 studies reported cerebrovascular events, 19 olfactory and oral dysfunctions, 5 systematic reviews on Guillen-Barré syndrome (GBS) and 8 articles on the sporadic manifestations like ocular signs and symptoms. The majority of the studies were classified as critically low or low in terms of quality. CONCLUSION Despite great heterogeneity in the current literature, neurological involvements are an important extra-pulmonary aspect of the COVID-19; most commonly in the form of general manifestations like headache and olfactory disturbances. Long-term effects of this virus on the nervous system must be a research priority for future references.

Abstract
COVID-19 has primarily been reported as a respiratory illness, but involvement of other organ systems has been reported. We describe a case of a postpartum with COVID-19 who had cerebral vasculitis. The patient presented with headache, blurring of vision, right-sided body weakness, and incoordination. Cranial magnetic resonance imaging (MRI) and angiography (MRA) showed a small acute hemorrhage on the left occipital lobe with associated acute subarachnoid hemorrhage along the parietal and occipital convexities and bilateral moderate to severe narrowing of the cerebral vessels. The patient was discharged asymptomatic. On follow-up, patient had no residual neurologic deficits, and repeat cranial MRI/MRA showed complete resolution of the vasculitis. This report was compatible with the pattern of viral-induced vasculitis and provides support to the mechanism of COVID-19-associated neurologic manifestation.

Abstract
Severe acute respiratory syndrome corona virus 2 hit strongly and hardly the entire globe for more than 1 year with a morbidity exceeding 139 million and a mortality approaching 3 million worldwide since its emergence in China in December 2019 until April 2021. Although being termed after its ancestor the acute respiratory syndrome corona virus that emerged in 2002. Yet, the current corona virus has its unique devastating presentations being pulmonary and extra pulmonary. In the current review, a highlight on the role played by corona virus 2 on pathogenesis and outcome of stroke is presented with an attempt to point to the most approved ways through which the corona virus induce stroke being disturbance in renin angiotensin system and angiotensin-converting enzyme 2 receptors downregulation, endothelial cell damage with coagulopathy, cytokine storm, and platelet as well as outcome and risks in patients who are suffering stroke with modifiable vascular risk factors and catching the severe acute respiratory syndrome corona virus 2.

Abstract
Purpose
This review aims to evaluate the evidence of the impact of COVID-19 on patients with stroke.
Design/methodology/approach
The author carried out a review following the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) for a review article. PubMed, the Web of Science and CINAHL Plus Full Text were searched from January 2019 to October 2020. Twenty-three studies were included in the final review, incorporating a total of 9,819 stroke patients.
Findings
The most commonly reported effects of COVID-19 on patients with stroke were delayed stroke treatment (n = 14 studies), thrombotic, blood and immune system complications (n = 8), increased risk of stroke severity and disability (n = 6), increased mortality (n = 8), elevated D-dimer levels (n = 4), comorbidity and acute respiratory distress syndrome (ARDS) (n = 6) and prolonged hospitalization (n = 4).
Originality/value
COVID-19 has affected patients with stroke in various ways, either directly or indirectly, prior to admission or in hospital. The findings should help guide further investigation of the long-term impact of COVID-19 on patients with stroke and help to establish proper guidelines for the provision of efficient treatment for affected patients.

Abstract
COVID-19 has been repeatedly related to a variety of extra-pulmonary manifestations since its emergence. COVID-19-positive patients have been shown to develop neurological deficits, deep venous thrombosis, acute kidney injury, acute hepatic injury, and myocarditis, among other conditions. The mechanism of some of these injuries remains unclear, but one factor that has been revealed is hypercoagulability. A hypercoagulable state, whether secondary to dysfunctional coagulation cascades or microvascular angiopathy, has been reported in the literature in COVID-19 patients. We present a case of a patient diagnosed with COVID-19 presented with venous thromboembolism and then shortly developed innumerable strokes.

Abstract
Ischemic stroke is one of the catastrophic neurological events that are being increasingly recognized among Coronavirus Disease (COVID)-19 patients. The recent studies have revealed about a possible connection among COVID-19, ischemic stroke, and excessive Neutrophil Extracellular Traps (NETs) formation. This paper establishes an overview of coronaviruses and NETs, NETs in pathogenesis of COVID-19 induced-ischemic stroke, and future directions using related recent literatures. NETs are normally functioned for a defense against pathogens, but in immoderate amount, they can trigger series of destructive events. Vasculopathy and neuroinflammation are the pathological mechanisms of NETs suggested to link COVID-19 and ischemic stroke. Based on newly discovered possible mechanisms, the potential clinical implications that could be applied consists of inhibition of NET formation, disrupting cholesterol synthesis, and interfering inflammatory pathway. A considerable number of scientific works are needed in order to complete the current understanding of the emerging relationship among COVID-19, NETs, and ischemic stroke. Although the exact mechanism is still unknown, these novel findings are a worthwhile contribution in defining future studies, suitable future frameworks, and therapeutic strategies.

Abstract
Patients with severe coronavirus disease 2019 (COVID-19) disease suffer from many thrombotic complications including deep vein thrombosis, pulmonary embolism, myocardial infarction (MI), and stroke. Large vessel strokes have been reported in young patients with COVID-19 disease. We report four cases of stroke diagnosed based on CT scan in critically ill individuals treated in the medical intensive care unit in a health facility in New York. All patients were receiving supportive treatment and mechanical ventilation at the time of diagnosis. All patients had impaired consciousness and were unable to wake up after sedation had worn off, prompting further workup. The pathogenesis of stroke could be secondary to the embolic phenomenon vs. hypercoagulopathy in our patients. Stroke should be considered in all COVID-19 patients who present with altered mental status. Severe COVID-19 patients with risk factors of stroke may benefit from therapeutic anticoagulation.

Abstract
AIMS In response to the rapid spread of COVID-19, this paper provides health professionals with better accessibility to available evidence, summarising findings from a systematic overview of systematic reviews of the neurological symptoms seen in patients with COVID-19. Implications of so-called 'Long Covid' on neurological services and primary care and similarities with other neurological disorders are discussed. METHODS Firstly, a systematic overview of current reviews of neurological symptoms of COVID-19 was conducted. Secondly, the implications of these findings are discussed in relation to the potential effect on neurological services and the similarities in the experience of patients with COVID-19 and those with other neurological disorders. A total of 45 systematic reviews were identified within seven databases, published between 11 April 2020 and 15 October 2020, following a search in June 2020, updated on 20 October 2020. RESULTS The results indicated that COVID-19 exhibits two types of neurological symptoms; life-threatening symptoms such as Guillain-Barre Syndrome (GBS) and encephalitis, and less devastating symptoms such as fatigue and myalgia. Many of these so-called lesser symptoms appear to be emerging as longer-term for some sufferers and have been recently labelled Long Covid. When compared, these less devastating symptoms are very similar to other neurological conditions such as chronic fatigue syndrome (CFS) and functional neurological disorder (FND). CONCLUSION Implications for neurological healthcare services in the United Kingdom (UK) may include longer waiting times and a need for more resources (including more qualified health professionals). There is also a possible change-effect on health professionals' perceptions of other neurological conditions such as CFS and FND. Future research is recommended to explore changes in health professionals' perceptions of neurological symptoms because of COVID-19.

Abstract
Background: In this study, we aimed to determine the global prevalence, chronological order of symptom appearance, and mortality rates with regard to hemorrhagic and ischemic stroke in patients with coronavirus disease 2019 (COVID-19) and to discuss possible pathogeneses of hemorrhagic and ischemic stroke in individuals with the disease. Methods: We searched the PubMed, Scopus, and Web of Science databases for relevant articles published up to November 8, 2020. Data regarding study characteristics, hemorrhagic stroke, ischemic stroke, and COVID-19 were retrieved in accordance with the PRISMA guidelines. The Newcastle-Ottawa scale was used to assess the quality of the eligible studies. The pooled prevalence and mortality rate of hemorrhagic and ischemic stroke were calculated. Results: The pooled estimate of prevalence of hemorrhagic stroke was 0.46% (95% CI 0.40%–0.53%;
I
2=89.81%) among 67,155 COVID-19 patients and that of ischemic stroke was 1.11% (95% CI 1.03%–1.22%;
I
2=94.07%) among 58,104 COVID-19 patients. Ischemic stroke was more predominant (incidence: 71.58%) than hemorrhagic stroke (incidence: 28.42%) in COVID-19 patients who experienced a stroke. In COVID-19 patients who experienced a stroke, hospital admission with respiratory symptoms was more commonly reported than that with neurological symptoms (20.83% for hemorrhagic stroke and 5.51% for ischemic stroke versus
6.94% for hemorrhagic stroke and 5.33% for ischemic stroke, respectively). The pooled mortality rate of COVID-19 patients who experienced a hemorrhagic and ischemic stroke was 44.72% (95% CI 36.73%–52.98%) and 36.23% (95% CI 30.63%–42.24%), respectively. Conclusions: Although the occurrence of hemorrhagic and ischemic stroke is low, the mortality rates of both stroke types in patients with COVID-19 are concerning, and therefore, despite several potential pathogeneses that have been proposed, studies aimed at definitively elucidating the mechanisms of hemorrhagic and ischemic stroke in individuals with COVID-19 are warranted.

Effect of the COVID-19 pandemic and the lockdown measures on the local stroke network. Neurol Sci 2021; 42:1237-1245. [PMID: 33452656 PMCID: PMC7810284 DOI: 10.1007/s10072-021-05045-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Accepted: 01/05/2021] [Indexed: 11/17/2022]
Abstract
Introduction The COVID-19 outbreak highly impacted the acute ischemic stroke care management. The primary end point of the study was to evaluate the impact of the COVID-19 outbreak and the following lockdown measures on our hub-and-spoke network; the secondary end point was to evaluate if the impact of the COVID-19 outbreak was different in hub-and-spoke centers. Methods This was a retrospective multicenter observational study conducted at the Stroke Units of Policlinico Gemelli, Ospedale San Filippo Neri, Ospedale di Belcolle, and Ospedale San Camillo de Lellis. We collected clinical reports of all consecutive patients admitted with diagnosis of acute ischemic stroke or transient ischemic attack (TIA) during the phase 1 of the lockdown period (11 March 2020–4 May 2020). As controls, we used all consecutive patients admitted for acute ischemic stroke or TIA in the same period of the previous year. Results A total of 156 and 142 clinical reports were collected in 2019 and 2020, respectively. During the COVID-19 outbreak, we observed a reduction of number of thrombolysis, a reduction of the length of hospitalization, and an increase of pneumonia. Regarding performance indicators, we observed an increase in onset-to-door time and in door-to-groin time. We did not observe any statistically significant interaction between year (2019 vs 2020) and facility of admission (hub vs spoke) on all variables analyzed. Discussion Our observational study, involving hub-and-spoke stroke network of a wide regional area, indicates that the COVID-19 outbreak impacted on the acute stroke management. This impact was equally observed in hub as well as in spoke centers.

Abstract
Ischemic stroke is a major cause of acute neurological symptoms in children with significant long-term neurological sequelae. Unlike in the adult population, the clinical presentation of strokes in children may not be stereotyped. Hence, many other differential diagnostic possibilities might have to be considered in the emergency setting. Due to this heterogeneous presentation and the resultant clinical dilemma in the early detection, acute thrombolysis even now remains as a very rarely tried therapeutic option in children. Many case reports over these years have shown consistently good results of acute intravenous thrombolysis in children with tissue plasminogen activator (tPA) administered within the time frame. There are also some recent reports of endovascular interventions. However, unlike in the adult population, class 1 clinical studies and good Randomized controlled trials (RCT) are yet to emerge in children. The absence of age-appropriate safety and outcome data for the commonly used thrombolytic agents in children is another major roadblock for developing clinical guidelines and recommendations for this age group. The ambitious Thrombolysis in Pediatric Stroke (TIPS) trial had to be terminated prematurely due to poor patient enrolment. This review critically looks at the current status of the acute management of ischemic strokes in children with a specific emphasis on thrombolytic therapy. Until we have better evidence-based guidelines for this age group, it will be prudent to develop robust institutional pathways to provide this important intervention for all eligible children with acute strokes.
