Short-Term Exposure to Fine Particulate Matter and Risk of Ischemic Stroke Brief Report
Conclusions—These findings suggest that short-term exposure to PM2.5 within 1 day before onset is associated with the subsequent occurrence of ischemic stroke.

Influenza vaccination and cardiovascular risk in patients with recent TIA and stroke
Conclusions: Influenza vaccination was not associated with reduced outcome events in patients with recent atherothrombotic ischemic stroke after considering all baseline characteristics (including concomitant medications) associated with influenza vaccination.

Evaluating Clinical Effectiveness of Pneumococcal Vaccination in Preventing Stroke: The CAPAMIS Study, 3-Year Follow-up
This study assessed clinical effectiveness of PPV23 in preventing ischemic stroke in people older than 60 years.Methods: We conducted a population-based cohort study involving 27,204 individuals of 60 years or older in Tarragona, Spain, who were prospectively followed from December 01, 2008, until November 30, 2011. Outcomes were neuroimaging-confirmed ischemic stroke, 30-day mortality from stroke, and all-cause death. Pneumococcal vaccination effectiveness was evaluated by Cox regression analyses, estimating hazard ratios (HRs) adjusted for age, sex, comorbidities, and influenza vaccine status.Results: Cohort members were...

Flu jab "may cut" stroke risk by a quarter
ConclusionThis research finds that, overall, having the flu vaccine reduced the risk of a person experiencing a stroke by about 25%. The reduction in risk seemed to be greatest within the first three months of vaccination, but remained for up to 12 months.  However, the effect lasted only if the vaccine was given early in the flu season (September to mid-November); giving the vaccine late in the flu season (mid-November to February) was not associated with significantly reduced risk.The research benefits from using data coded within the General Practice Research Database for England and Wales for almost 50,000 people with...

Increased Plasma Matrix Metalloproteinase-9 Levels Contribute to Intracerebral Hemorrhage during Thrombolysis after Concomitant Stroke and Influenza Infection
Conclusion: Preexisting influenza A virus infection led to increased plasma MMP-9 and TIMP-1 levels in mice undergoing thrombolysis after induced stroke. MMP-9 levels closely correlated with intracerebral bleeding after thrombolysis during concomitant infection and stroke. Thus, our data indicate that thrombolysis may be dangerous during influenza infection. MMP-9 inhibitors might be considered to reduce the side effects of thrombolysis during concomitant infection and stroke.Cerebrovasc Dis Extra 2016;6:50-59

Influenza and pneumococcal vaccination and risk of stroke or transient ischaemic attack-Matched case control study.
CONCLUSIONS: Influenza vaccination was associated with a 24% reduction in risk of stroke but not TIA. Pneumococcal vaccination was not associated with reduced risk of stroke or TIA. This has important implications for potential benefits of influenza vaccine. PMID: 24486370 [PubMed - as supplied by publisher]

Air pollution and humidity as triggering factors for stroke. Results of a 12-year analysis in the West Paris area.
CONCLUSIONS: This study suggests that short-term exposure to air pollution and a high level of humidity are associated with a significant excess relative risk of calls for suspected stroke. PMID: 31030900 [PubMed - as supplied by publisher]

Influenza vaccination and risk of stroke: Self-controlled case-series study.
CONCLUSIONS: Influenza vaccination is associated with a reduction in incidence of stroke. This study supports previous studies which have shown a beneficial association of influenza vaccination for stroke prevention. PMID: 26296496 [PubMed - as supplied by publisher]

Influenza vaccination might reduce the risk of ischemic stroke in patients with atrial fibrillation: A population-based cohort study.
Conclusions: Influenza vaccination might exert a dose-response effect against ischemic stroke in patients with AF who have risk factors for ischemic stroke by reducing the incidence of ischemic stroke, particularly in those aged 65-74 and ≥75 y. PMID: 29348857 [PubMed]

Effect of Influenza Vaccination on Risk of Stroke: A Systematic Review and Meta-Analysis
Background: Despite the presence of a strong association between influenza infection and stroke, whether influenza vaccination reduces the risk of stroke is yet a matter of controversy. We conducted a meta-analysis to determine whether influenza vaccination protects against stroke.Methods: We searched PubMed, EMBASE, and the Cochrane Library from database inception date to November 18, 2016, without language restrictions, to identify studies investigating the effect of influenza vaccination on subsequent risk of stroke. We conducted a meta-analysis to quantify the risk of stroke in overall and subgroup analyses and calcula...

The emerging association between COVID-19 and acute stroke
Trends Neurosci. 2021 Apr 8:S0166-2236(21)00071-0. doi: 10.1016/j.tins.2021.03.005. Online ahead of print.ABSTRACTPrior to COVID-19, only two human-tropic coronaviruses resulted in epidemics and cerebrovascular disease was rarely reported. Evidence now suggests that 1-6% of hospitalized COVID-19 patients develop stroke. According to some reports, stroke risk is more than sevenfold greater in patients with COVID-19 than influenza. Concerningly, outcomes of COVID-19-related stroke are often worse than in stroke patients without COVID-19 from the same cohorts. In this review, we highlight the emerging association between COVI...
