Abstract
BACKGROUND AND PURPOSE Cerebral small vessel disease is a common manifestation among patients with Fabry disease (FD). As a biomarker of cerebral small vessel disease, the prevalence of impaired cerebral autoregulation as assessed by transcranial Doppler (TCD) ultrasonography was evaluated in FD patients and healthy controls. METHODS TCD was performed to assess pulsatility index (PI) and vasomotor reactivity expressed by breath-holding index (BHI) for the middle cerebral arteries of included FD patients and healthy controls. Prevalence of increased PI (>1.2) and decreased BHI (<0.69) and ultrasound indices of cerebral autoregulation were compared in FD patients and controls. The potential association of ultrasound indices of impaired cerebral autoregulation with white matter lesions and leukoencephalopathy on brain MRI in FD patients was also evaluated. RESULTS Demographics and vascular risk factors were similar in 23 FD patients (43% women, mean age: 51 ± 13 years) and 46 healthy controls (43% women, mean age: 51 ± 13 years). The prevalence of increased PI (39%; 95% confidence interval [CI]: 20%-61%), decreased BHI (39%; 95% CI: 20%-61%), and the combination of increased PI and/or decreased BHI (61%; 95% CI: 39%-80%) was significantly (p < .001) higher in FD patients compared to healthy controls (2% [95% CI: 0.1%-12%], 2% [95% CI: 0.1%-12%], and 4% [95% CI: 0.1%-15%], respectively). However, indices of abnormal cerebral autoregulation were not associated independently with white matter hyperintensities and presented a low-to-moderate predictive ability for the discrimination of FD patients with and without white matter hyperintensities. CONCLUSIONS Impaired cerebral autoregulation as assessed by TCD appears to be highly more prevalent among FD patients compared to healthy controls.

Abstract
In the last decade, ultrasound examination in neurology has been undergoing a significant expansion of its modalities. In parallel, there is an increasing demand for rapid and high-quality diagnostics in various acute diseases in the prehospital setting, the emergency room, intensive care unit, and during surgical or interventional procedures. Due to the growing need for rapid answers to clinical questions, there is particular demand for diagnostic ultrasound imaging. The Neuro-POCUS working group, a joint project by the European Academy of Neurology Scientific Panel Neurosonology, the European Society of Neurosonology and Cerebral Hemodynamics, and the European Reference Centers in Neurosonology (EAN SPN/ESNCH/ERcNsono Neuro-POCUS working group), was given the task of creating a concept for point-of-care ultrasound in neurology called "Neuro-POCUS". We introduce here a new ultrasound examination concept called point-of-care ultrasound in neurology (Neuro-POCUS) designed to streamline conclusive imaging outside of the ultrasound center, directly at the bedside. The aim of this study is to encourage neurologists to add quick and disease-oriented Neuro-POCUS to accompany the patient in the critical phase as an adjunct not a substitution for computed tomography, magnetic resonance imaging, or standard comprehensive neurosonology examination. Another goal is to avoid unwanted complications during imaging-free periods, ultimately resulting in advantages for the patient.

Abstract
Background and purpose The experience gained during the first COVID‐19 wave could have mitigated the negative impact on stroke care in the following waves. Our aims were to analyze the characteristics and outcomes of patients with stroke admitted during the second COVID‐19 wave and to evaluate the differences in the stroke care provision compared with the first wave. Methods This retrospective multicenter cohort study included consecutive stroke patients admitted to any of the seven hospitals with stroke units (SUs) and endovascular treatment facilities in the Madrid Health Region. The characteristics of the stroke patients with or without a COVID‐19 diagnosis were compared and the organizational changes in stroke care between the first wave (25 February to 25 April 2020) and second wave (21 July to 21 November 2020) were analyzed. Results A total of 550 and 1191 stroke patients were admitted during the first and second COVID‐19 waves, respectively, with an average daily admission rate of nine patients in both waves. During the second wave, there was a decrease in stroke severity (median National Institutes of Health Stroke Scale 5 vs. 6; p = 0.000), in‐hospital strokes (3% vs. 8.1%) and in‐hospital mortality (9.9% vs. 15.9%). Furthermore, fewer patients experienced concurrent COVID‐19 (6.8% vs. 19.1%), and they presented milder COVID‐19 and less severe strokes. Fewer hospitals reported a reduction in the number of SU beds or deployment of SU personnel to COVID‐19 dedicated wards during the second wave. Conclusions During the second COVID‐19 wave, fewer stroke patients were diagnosed with COVID‐19, and they had less stroke severity and milder COVID‐19.

Abstract
To estimate the impact on emergency attendance for stroke and acute myocardial infarction (AMI) during the pandemic of COVID-19 in Beijing, China. Based on 17,123 and 8693 emergency attendance for stroke and AMI, an interrupted time-series (ITS) study was conducted. Since 01/24/2020, the top two levels of regulations on major public health have been implemented in Beijing. This study covered from 03/01/2018 to 06/03/2020, including 19 weeks of lockdown period and 99 weeks before. A segmented Poisson regression model was used to estimate the immediate change and the monthly change in the secular trend of the emergency attendance rates. The emergency attendance rates of stroke and AMI cut in half at the beginning of the lockdown period, with 52.1% (95% CI 45.8% to 57.7%) and 63.1% (95% CI 56.1% to 63.1%) immediate decreases for stroke and AMI, respectively. Then during the lockdown period, 7.0% (95% CI 2.5%, 11.6%) and 16.1% (95% CI 9.5, 23.1) increases per month in the secular trends of emergency attendance rates were shown for stroke and AMI, respectively. Though the accelerated increasing rates, there were estimated 1335 and 747 patients with stroke and AMI without seeking emergency medical aid during the lockdown, respectively. The emergency attendance for stroke and AMI cut in half at the beginning of the pandemic then had gradual restoration thereafter. The results hint the need for more engagement and communications with all stakeholders to reduce the negative impact on CVD emergency medical services during the crisis.

Abstract
Coronavirus disease 2019 (COVID-19) is a global pandemic where several comorbidities have been shown to have a significant effect on mortality. Patients with diabetes mellitus (DM) have a higher mortality rate than non-DM patients if they get COVID-19. Recent studies have indicated that patients with a history of diabetes can increase the risk of severe acute respiratory syndrome coronavirus 2 infection. Additionally, patients without any history of diabetes can acquire new-onset DM when infected with COVID-19. Thus, there is a need to explore the bidirectional link between these two conditions, confirming the vicious loop between "DM/COVID-19". This narrative review presents (1) the bidirectional association between the DM and COVID-19, (2) the manifestations of the DM/COVID-19 loop leading to cardiovascular disease, (3) an understanding of primary and secondary factors that influence mortality due to the DM/COVID-19 loop, (4) the role of vitamin-D in DM patients during COVID-19, and finally, (5) the monitoring tools for tracking atherosclerosis burden in DM patients during COVID-19 and "COVID-triggered DM" patients. We conclude that the bidirectional nature of DM/COVID-19 causes acceleration towards cardiovascular events. Due to this alarming condition, early monitoring of atherosclerotic burden is required in "Diabetes patients during COVID-19" or "new-onset Diabetes triggered by COVID-19 in Non-Diabetes patients".

Abstract
PURPOSE OF REVIEW The coronavirus disease 2019 (COVID-19) pandemic has caused a major impact on stroke care. This review synthesizes the available data and provides a framework for optimal management of stroke patients with confirmed or suspected COVID-19 infection and eligible to reperfusion treatments. RECENT FINDINGS Reorganization of health services has led to the conversion of stroke units and relocation of stroke staff to COVID units. During the pandemic surge, there has been a general decline of stroke presentations, increased time delays, and reduced activity across all areas of stroke care, specifically the delivery of acute treatment. Moreover, COVID-19 patients seem to have a worse outcome despite prompt recanalization. Periprocedural monitoring studies are needed in these patients to target a more adequate therapy. SUMMARY The COVID-19 pandemic has jeopardized the ability of stroke centers to provide timely assessment and acute therapies such as reperfusive treatments. Yet, as stroke remains a medical emergency, efforts to maintain stroke teams and safe provision of highly effective stroke treatments should be prioritized despite healthcare systems reorganization. This can be accomplished through the activation of telestroke networks, protected stroke pathways, 24/7 open-access high-quality stroke centers, and stroke awareness programs.

Abstract
Objective To report six consecutive patients with confirmed coronavirus disease-2019 (COVID-19) who underwent Transcranial Doppler (TCD) ultrasonography evaluation for cerebral microemboli in the setting of suspected or confirmed acute ischemic stroke. Methods Patient data were obtained from medical records from Northwestern Memorial Hospital, Chicago, IL between May and June 2020. All patients with confirmed COVID-19 who underwent clinical TCD ultrasonography for microemboli detection were included. Results A total of eight TCD studies were performed in six patients with COVID-19 (4 men and 2 women, median age 65±5), four with confirmed ischemic stroke and two with refractory encephalopathy. Microemboli were detected in three male patients, two patients had suffered a confirmed ischemic stroke and one who developed prolonged encephalopathy. Microemboli of varying intensity were identified in multiple vascular territories in two patients, and microemboli persisted despite therapeutic anticoagulation in a third patient. Of the three patients without evidence of microemboli on TCD ultrasonography, two patients had suffered a confirmed ischemic stroke, while one remained with refractory encephalopathy. Conclusions TCD ultrasonography for microemboli detection identified three patients with confirmed COVID-19 with evidence of cerebral arterial microemboli, including one who was therapeutically anticoagulated. TCD ultrasonography provides a non-invasive method for evaluating cerebral microemboli in patients with COVID-19 and may be useful in assessing response to treatment in cases with suspected or confirmed disorders of hypercoagulability. Further studies investigating the prevalence of cerebral microemboli and associated risk factors are needed to characterize their pathogenic mechanism and guide therapeutic interventions in hospitalized COVID-19 patients.

Abstract
Neurological manifestations are not uncommon during infection with the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A clear association has been reported between cerebrovascular disease and coronavirus disease 2019 (COVID-19). However, whether this association is causal or incidental is still unknown. In this narrative review, we sought to present the possible pathophysiological mechanisms linking COVID-19 and cerebrovascular disease, describe the stroke syndromes and their prognosis and discuss several clinical, radiological, and laboratory characteristics that may aid in the prompt recognition of cerebrovascular disease during COVID-19. A systematic literature search was conducted, and relevant information was abstracted. Angiotensin-converting enzyme-2 receptor dysregulation, uncontrollable immune reaction and inflammation, coagulopathy, COVID-19-associated cardiac injury with subsequent cardio-embolism, complications due to critical illness and prolonged hospitalization can all contribute as potential etiopathogenic mechanisms leading to diverse cerebrovascular clinical manifestations. Acute ischemic stroke, intracerebral hemorrhage, and cerebral venous sinus thrombosis have been described in case reports and cohorts of COVID-19 patients with a prevalence ranging between 0.5% and 5%. SARS-CoV-2-positive stroke patients have higher mortality rates, worse functional outcomes at discharge and longer duration of hospitalization as compared with SARS-CoV-2-negative stroke patients in different cohort studies. Specific demographic, clinical, laboratory and radiological characteristics may be used as ‘red flags’ to alarm clinicians in recognizing COVID-19-related stroke.

Wu Y, Chen F, Wang Z, Feng W, Liu Y, Wang Y, Song H. Reductions in Hospital Admissions and Delays in Acute Stroke Care During the Pandemic of COVID-19. Front Neurol 2020; 11:584734. [PMID: 33250851 PMCID: PMC7674953 DOI: 10.3389/fneur.2020.584734] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Accepted: 09/14/2020] [Indexed: 01/01/2023] Open
Abstract
Background: Rapid and effective medical care for stroke is paramount to achieve maximal functional recovery. Because of the wide spreading of the coronavirus disease in 2019 (COVID-19), acute stroke care is negatively impacted. How much acute care for stroke has been affected during the pandemic remains to be assessed. Methods: The first-level response to major public health was launched from January 24th to April 29th, 2020 in Beijing to contain the spread of COVID-19. Based on a database connecting all 77 stroke centers, the quantity and quality in emergency care for stroke during the 97 lockdown days were compared with the equivalent period in 2019. During the pandemic, 15 of the 77 stroke centers were designated to receive patients sick with COVID-19. Subgroup analyses were carried out by different types of hospitals (designated and undesignated). Results: There were 1,281 and 2,354 stroke emergency hospital admissions in the lockdown period and the parallel period in 2019, respectively. A reduction of 45.6% in admission was shown in the lockdown period, with more reductions for hemorrhagic stroke (69.0%) compared with ischemic stroke (42.9%). More reductions happened in COVID-19 designated hospitals (52.6%) compared with undesignated hospitals (41.8%). The mean NIHSS score at hospital arrival was significantly higher in the lockdown period (9.4 ± 7.7 in 2020 vs. 8.4 ± 7.8 in 2019, P < 0.001). For the metrics measuring the quality of acute stroke care, the onset to door (OTD), onset to needle (ONT), and onset to recanalization (OTR) times didn't change significantly, while significant delays are shown for the door to CT scan (DTC, 1 min delay), door to needle (DTN, 4 min delays), and door to puncture (DTP, 29 min delays) times, which mainly happened in COVID-19 undesignated hospitals. Conclusions: Profound reductions in stroke hospital admissions and significant delays in emergency care for acute ischemic stroke occurred during the pandemic of COVID-19. Engagement and effective communication with all stakeholders including patients, health care providers, governmental policymakers, and other implementation partners are required for future success in similar crises.

Abstract
We describe a case of a 47-year-old Italian, immunocompromised, and obese woman infected by COVID-19 presenting with fever (39.6 °C) and respiratory symptoms. Neurological examination was normal. Chest CT findings consist of bilateral interstitial pneumonia (visual score extension: 30%). The patient was treated with antiviral drugs and anti-inflammatory drugs with supportive care. Seven days after admission to Covid-19 Unit, the patient rapidly developed worsening respiratory failure and acute respiratory distress syndrome (ARDS). She suddenly developed partial left hemispheric syndrome. A new HRCT scan of her thorax revealed diffuse ground-glass opacities in both lungs (visual score extension: 90%). Brain CT performed 2 h after sudden-onset left-sided weakness showed subtle low attenuation within the right insular ribbon and frontal lobe (ASPECT Score 8). Multiphasic CT angiography (MCTA) demonstrated occlusion of both the dominant inferior division of the right middle cerebral artery and the A2 segment of the right anterior cerebral artery. After 24 h, her pupils became dilated and unreactive, and brain CT demonstrated large bilateral infarctions of both the cerebellar and cerebral hemispheres. She had a rapid progression of interstitial pneumonia from COVID-19, developed multiple strokes, and died 1 day later. SARS-CoV-2 infection seems to predispose pluripathological subjects to cerebrovascular complications.
