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...

Cross-level interaction between individual socioeconomic status and regional deprivation on overall survival after onset of ischemic stroke: National health insurance cohort sample data from 2002 to 2013.
CONCLUSION: Although we need to perform further investigations to determine the exact mechanisms, regional deprivation, as well as medical factors, might be associated with survival after onset of ischemic stroke in low-income patients. PMID: 28688749 [PubMed - as supplied by publisher]

The mediating role of the venules between smoking and ischemic stroke
This study was part of a population-based study including 9109 stroke-free persons participated in the study in 1990, 2004, or 2006 (mean age: 63.7  years; 58% women). Smoking behavior (smoking versus non-smoking) was identified by interview. Retinal venular calibers were measured semi-automatically on retinal photographs. Incident strokes were assessed until January 2016. A regression-based approach was used with venular calibers as mediator to decompose the total effect of smoking compared to non-smoking into four components: controlled direct effect (neither mediation nor interaction), pure indirect effect (mediation o...

Hypothetical blood-pressure-lowering interventions and risk of stroke and dementia
AbstractWe aimed to study  the effects of hypothetical interventions on systolic blood pressure (SBP) and smoking on risk of stroke and dementia using data from 15 years of follow-up in the Rotterdam Study. We used data from 4930 individuals, aged 55–80 years, with no prior history of stroke, dementia or cognitive impai rment, followed for 15 years within the Rotterdam Study, a population-based cohort. We defined the following sustained interventions on SBP: (1) maintaining SBP below 120 mmHg, (2) maintaining SBP below 140 mmHg, (3) reducing SBP by 10% if above 140 mmHg, (4) reducing SBP by 20% if above 140 mm Hg...

Increased Incidence of Stroke and Transient Ischemic Attack in Patients with Rheumatoid Arthritis and Ankylosing Spondylitis in Germany
Conclusion: RA was significantly associated with stroke and TIA, with young patients being at a particularly increased risk. AS was tendentially associated with stroke and TIA.Neuroepidemiology

Predictive Value of Pediatric Stroke Diagnoses in Administrative Data: A Systematic Literature Review
Conclusion Caution is recommended in the use and interpretation of non-validated administrative data for pediatric stroke. Data on the PPV and sensitivity of pediatric stroke diagnoses in administrative data remain limited and are only available from high-income countri es.

Identifying applications of virtual reality to benefit the stroke translational pipeline
Brain Neurosci Adv. 2023 Jun 21;7:23982128231182506. doi: 10.1177/23982128231182506. eCollection 2023 Jan-Dec.ABSTRACTAs a leading cause of mortality and morbidity, stroke and its management have been studied extensively. Despite numerous pre-clinical studies identifying therapeutic targets, development of effective, specific pharmacotherapeutics remain limited. One significant limitation is a break in the translational pipeline - promising pre-clinical results have not always proven replicable in the clinic. Recent developments in virtual reality technology might help generate a better understanding of injury and recovery...

Protocol for a randomized controlled clinical trial investigating the effectiveness of Fast muscle Activation and Stepping Training (FAST) for improving balance and mobility in sub-acute stroke
DiscussionThe targeted training of fast functional movements in the FAST program is expected to improve walking balance following stroke compared to the active control intervention. Unique to this study is the investigation of potential mechanisms associated with improvements in walking balance.Trial registrationClinicalTrials.gov NCT01573585

Supplemental oxygen delivery to suspected stroke patients in pre hospital and emergency department settings
Background: Recent data suggests that high-flow oxygen started promptly after stroke symptom onset salvages ischemic brain tissue. We investigated the consistency of oxygen delivery to suspected stroke patients in the pre-hospital (PH) and Emergency Department (ED) settings, and associated adverse events (AEs). Methods: We retrospectively reviewed pre-hospital call reports of suspected stroke patients transported by our institution's paramedics. We extracted data on oxygen delivery in the PH and ED settings, demographics, Glasgow Coma Scale score (GCS), final diagnosis, and selected AEs (mortality, seizures, worsening neur...

Dysphagia and Factors Associated with Respiratory Infections in the First Week Post Stroke
Conclusion: This study of a large cohort of acute stroke patients supports research indicating aspiration pneumonia is multifactorial in nature. NGT were associated with increased risk of respiratory infections and may contribute to infections by promoting oropharyngeal colonisation. Patients with severely impaired mobility were also at very high risk of respiratory infection.Neuroepidemiology 2014;43:140-144

The Incidence of the First-Ever Stroke in a Mediterranean Island Population: The Isle of Lesvos Stroke Study
Conclusions: The present findings indicate that the incidence of FES in the studied Mediterranean population is at the low end of the range of estimates established by recent European registers. The results of the present study extend the limited epidemiological data on stroke in Greece and can help guide future monitoring, prevention and treatment strategies.Neuroepidemiology 2014;43:206-212

The Impact of Green Tea Consumption on the Prevention of Hemorrhagic Stroke
Conclusions: Consumption of green tea may protect against hemorrhagic stroke, whereas consumption of black tea may have no meaningful effect on risk.Neuroepidemiology 2015;44:215-220
