Clinical characteristics of patients with acute ischemic stroke previously vaccinated against COVID-19
The aim of this study was to examine the clinical characteristics of patients with acute ischemic stroke which were previously vaccinated against Coronavirus Disease 2019 (COVID-19) and determine whether the vaccine had impact on outcome.

Clinical Characteristics of Patients with Acute Ischemic Stroke Previously Vaccinated Against COVID-19
CONCLUSIONS: There are no significant differences in clinical characteristics of stroke in vaccinated compared to unvaccinated patients. We did not find a connection between vaccination and stroke.PMID:35447380 | PMC:PMC8977441 | DOI:10.1016/j.jstrokecerebrovasdis.2022.106483

Global research trends on COVID-19 and stroke: A bibliometric analysis
ConclusionOur bibliometric analysis provides a comprehensive overview of the current state of research on COVID-19 and stroke and highlights key areas of focus in the field. Optimizing the treatment of COVID-19-infected stroke patients and elucidating the underlying pathogenic mechanisms of COVID-19 and stroke co-morbidity are key areas of future research that will be beneficial in improving the prognosis of stroke patients during the ongoing COVID-19 epidemic.

Factors associated with stroke after COVID-19 vaccination: a statewide analysis
ConclusionConcurrent COVID-19 infection had the strongest association with early ischemic and hemorrhagic stroke after the first dose of COVID-19 vaccination. Although not all determinants of stroke, particularly comorbidities, were considered in this analysis, the Ad26.COV2.S vaccine was associated with a higher risk of early post-vaccination ischemic stroke than BNT162b2.

Ischemic Stroke and Vaccine-Induced Immune Thrombotic Thrombocytopenia following COVID-19 Vaccine: A Case Report with Systematic Review of the Literature
Conclusion: Our study points out that, in addition to cerebral venous thrombosis, adenoviral vector-based vaccines also appear to have a cerebral arterial thrombotic risk, and clinicians should be aware that ischemic stroke with LVO, although rare, could represent a clinical presentation of VITT.Cerebrovasc Dis

E-086 The effect of covid-19 vaccines on stroke outcomes: a single-center study
ConclusionAlthough vaccination did not show any significant difference in stroke patient outcomes on follow-up, vaccines were associated with lower rates of morbidity and mortality at discharge among stroke patients during the pandemic.Abstract E-086 Table 1Comparison of outcomes between COVID-19-positive unvaccinated vs. fully vaccinated patients presenting with stroke.*Adjusted for hypertension, atrial fibrillation, PVD, admission NIHSS, ASPECTS, tandem occlusion, and thrombectomy Unvaccinated Vaccinated Effect Variable Unadjusted Value (95% CI ) Unadjusted p-value Adjusted Value (95% CI )* Adjusted p-value* Primary Out...

Insights Into Immunothrombotic Mechanisms in Acute Stroke due to Vaccine-Induced Immune Thrombotic Thrombocytopenia
In conclusion, insufficient resolution of NETs, e.g. by endogenous DNases or protection of NETs against degradation by embedded factors like the antimicrobial peptide LL-37 might thus be an important factor in the pathology of VITT besides increased NET-formation. On the basis of these findings, we discuss the potential implications of the mechanisms of disturbed NETs-degradation for diagnostic and therapeutic approaches in VITT-related thrombogenesis, other auto-immune disorders and beyond.

Patent Foramen Ovale-associated Stroke and COVID-19 Vaccination
Case –control studies have shown an association between patent foramen ovale (PFO) and cryptogenic stroke, which was observed particularly in patients younger than 55 years without conventional risk factors. The role of PFO closure in preventing stroke recurrence had been uncertain for many years, unt il four randomised clinical trials in 2017 and 2018 unequivocally demonstrated a benefit, with the number needed t...

Brain perfusion single photon emission computed tomography abnormality in MRI-negative stroke-like patients post COVID-19 vaccination
Stroke-like symptoms after COVID-19 vaccination was thought to be functional if there was no anatomical image abnormality. We aimed to analyze brain perfusion changes in these patients. A case-control study of brain perfusion single photon emission computed tomography (SPECT) of 12 vaccinated patients with left-sided stroke-like symptoms were compared with 12 age- and gender-matched normal interictal brain SPECTs using voxel-based analysis. Significant hyperperfusion was seen on the right side in postcentral, inferior parietal, mid temporal, parahippocampal, and caudate regions, and on the left side in the thalamus, hippoc...

Adverse events following COVID ‐19 mRNA vaccines: A systematic review of cardiovascular complication, thrombosis, and thrombocytopenia
ConclusionAvailable literature includes more studies with the BNT162b2 vaccine than mRNA-1273. Future studies must report mortality and adverse cardiovascular events by vaccine types.

Changes in incidence rates of outcomes of interest in vaccine safety studies during the COVID-19 pandemic
CONCLUSION: Rates of some clinical outcomes during the pandemic changed and should not be used as historical background rates in vaccine safety studies. Inclusion of telehealth visits should be considered for vaccine studies involving Bell's palsy, ITP, and narcolepsy/cataplexy.PMID:35465977 | DOI:10.1016/j.vaccine.2022.04.037
