Change in the Estimated Glomerular Filtration Rate Over Time and Risk of First Stroke in Hypertensive Patients
CONCLUSION: In Chinese hypertensive patients, both the decline and increase of eGFR levels were independently associated with the risks of first stroke or first ischemic stroke.PMID:35400712 | DOI:10.2188/jea.JE20210242

Epidemiological evidence on association between ambient air pollution and stroke mortality
Conclusions This study provides new evidence for the association between exposure to ambient air pollution and stroke mortality. Our results also suggest that underlying cardiac disorder may increase the risk for ischaemic-stroke mortality in relation to air pollution exposure, especially NO2. .

Response shift recalibration and reprioritization in health-related quality of life was identified prospectively in older men with and without stroke
Conclusion: This study is unique in our ability to prospectively identify RS recalibration and reprioritization in HRQL in aging men with stroke and remaining free of stroke. Changes in the meaning of self-evaluation of HRQL occur not only with stroke but also in men who remain free of stroke.

Evaluating an extended rehabilitation service for stroke patients (EXTRAS): study protocol for a randomised controlled trial
This study is a multicentre randomised controlled trial with health economic and process evaluations. It is set within NHS stroke services which provide ESD. Participants are adults who have experienced a new stroke (and carer if appropriate), discharged from hospital under the care of an ESD team.The intervention group receives an extended stroke rehabilitation service provided for 18 months following completion of ESD. The extended rehabilitation service involves regular contact with a senior ESD team member who leads and coordinates further rehabilitation. Contact is usually by telephone. The control group receives usu...

Rapid weather changes are associated with increased ischemic stroke risk: a case-crossover study
Abstract Observational studies focusing on absolute meteorological values suggest an association between meteorological parameters and stroke risk but these results are inconsistent and conflicting. Since changes in weather can provoke atrial fibrillation, we examined the association between rapid weather changes and stroke risk in 1694 patients with determinable onset of stroke symptoms in a case-crossover study in central Germany. Days one to three before stroke onset were classified as hazard periods and day seven as the respective control period. Risk of ischemic stroke in relation to 24 h differences in mean...

Causes of Death Data in the Global Burden of Disease Estimates for Ischemic and Hemorrhagic Stroke
Conclusions: A large proportion of stroke fatalities are derived from the redistribution of ‘unspecified stroke' and ‘hypertension' with marked regional differences. Future advancements in stroke certification, data collections and statistical analyses may improve the estimation of the global stroke burden.Neuroepidemiology 2015;45:152-160

Incidence of stroke and stroke subtypes in chronic obstructive pulmonary disease
Abstract It is uncertain whether the incidence of stroke is increased in patients with chronic obstructive pulmonary disease (COPD), and whether COPD is associated with all subtypes of stroke (i.e. ischemic stroke, intracerebral haemorrhage and subarachnoid haemorrhage). We evaluated the association between COPD and incidence of stroke in a nation-wide cohort study. All individuals between 40 and 84 years of age, hospitalised for COPD between 1987 and 2003 in Sweden were identified in the Swedish hospital discharge register. For each COPD patient (n = 103,419), one reference individual was randomly selected fro...

Validation of Hospital Performance Measures of Acute Stroke Care Quality. Riksstroke, the Swedish Stroke Register
Conclusions: A nationwide stroke care register can be maintained with sufficient data quality to permit between-hospital performance benchmarking. Our experiences may serve as a model for other stroke registers while evaluating data quality.Neuroepidemiology 2016;46:229-234

The impact of preadmission oral bisphosphonate use on 30-day mortality following stroke: a population-based cohort study of 100,043 patients
Conclusion: We found no overall evidence that preadmission bisphosphonate use increases 30-day mortality following stroke. Keywords: prognosis, oral bisphosphonates, stroke, mortality, cardiovascular disease, osteoporosis treatment

Differentiating Incident from Recurrent Stroke Using Administrative Data: The Impact of Varying Lengths of Look-Back Periods on the Risk of Misclassification
Conclusion: Hospital administrative data sets linked to prior admissions can be used to distinguish recurrent from incident stroke. The risk of misclassifying recurrent stroke cases as incident events is negligible with a look-back period of 10 years.Neuroepidemiology 2017;48:111-118

Use of Outpatient Rehabilitation Among Adult Stroke Survivors - 20 States and the District of Columbia, 2013, and Four States, 2015.
Abstract Stroke is a leading cause of mortality and disability in the United States (1,2). Approximately 800,000 American adults experience a stroke each year (2,3). Currently, approximately 6 million stroke survivors live in the United States (2). Participation in stroke rehabilitation (rehab), which occurs in diverse settings (i.e., in-hospital, postacute care, and outpatient settings), has been determined to reduce stroke recurrence and improve functional outcomes and quality of life (3,4). Despite longstanding national guidelines recommending stroke rehab, it remains underutilized, especially in the outpatient...

Forty-year Seasonality Trends in Occurrence of Myocardial Infarction, Ischemic Stroke, and Hemorrhagic Stroke
Conclusions: We found no substantial seasonality for MI, ischemic stroke, or hemorrhagic stroke occurrence during 1977−2016. Modest peak-to-trough ratios should be interpreted after considering bias induced by random variation.
