Effects of concurrent depressive symptoms and perceived stress on cardiovascular risk in low- and high-income participants: findings from the Reasons for Geographical and Racial Differences in Stroke (REGARDS) study.
Using data from the Reasons for Geographical and Racial Differences in Stroke (REGARDS) study, the authors examined associations among depressive symptoms and stress, alone and in combination, and incident cardiovascular disease (CVD) and all-cause mortality as a function of socioeconomic status. They found that screening for a combination of elevated depressive symptoms and stress in low-income persons may help identify those at increased risk of incident CVD and mortality.

Refining stroke prediction in atrial fibrillation patients by addition of African-American ethnicity to CHA2DS2-VASc score.
The authors hypothesized that the addition of African-American ethnicity to the CHA2DS2-VASc score might improve stroke prediction in patients with atrial fibrillation (AF). They found that, in patients over age 65 with newly diagnosed AF, the addition of ethnicity to CHA2DS2-VASc score significantly improved stroke prediction.

Field assessment stroke triage for emergency destination: a simple and accurate prehospital scale to detect large vessel occlusion strokes.
The authors aimed to develop a simple field scale to identify large vessel occlusion strokes (LVOS). They found that Field Assessment Stroke Triage for Emergency Destination (FAST-ED) is a simple scale that, if successfully validated in the field, may be used by medical emergency professionals to identify LVOS in the prehospital setting enabling rapid triage of patients.

Reassessing the stroke belt: using small area spatial statistics to identify clusters of high stroke mortality in the United States.
The researchers identified clusters of high stroke mortality and adjacent areas of low stroke mortality for US counties and evaluated for regional differences in county-level risk factors. They found that clusters of high stroke mortality exist beyond the 8-state stroke belt, and variation exists within the stroke belt. They recommended reconsideration of the stroke belt definition and suggested increased attention to local determinants of health underlying small area regional variability to inform targeted healthcare interventions.

Associations between hematopoietic growth factors and risks of venous thromboembolism, stroke, ischemic heart disease and myelodysplastic syndrome: findings from a large population-based cohort of women with breast cancer.
The researchers sought to determine the risk of venous thromboembolism (VTE), stroke, ischemic heart disease, and myelodysplastic syndrome (MDS) in association with the receipt of colony-stimulating factors (CSFs) and/or erythropoiesis-stimulating agents (ESAs) in women with breast cancer. They found that receipts of CSFs and ESAs were significantly associated with an increased risk of VTE in women with breast cancer.

Paramedic perspectives on barriers to prehospital acute stroke recognition.
The researchers aimed to understand systematically the challenges and barriers faced by paramedics in recognizing stroke presentations in the field. They concluded that while challenges to stroke recognition in the field were slightly different for rural and urban emergency medical service providers, participants concurred that timely, systematic feedback on individual patients and case-based training would strengthen early stroke recognition skills.

Assessment of home-time after acute ischemic stroke in Medicare beneficiaries.
The researchers evaluated home-time as a patient-centered outcome in Medicare beneficiaries with ischemic stroke in comparison with modified Rankin Scale (mRS) score at 90 days and at 1 year post event. They concluded that in a population of older patients with ischemic stroke, home-time was readily available from administrative data and associated with mRS at 90 days and 1 year.

Association of hyperlipidaemia, inflammation and serological status and coronary heart disease among patients with rheumatoid arthritis: data from the National Veterans Health Administration.
The researchers studied the association of serum lipids, inflammation, and seropositivity on coronary heart disease (CHD) and stroke in patients with rheumatoid arthritis. They found that in the study population of predominantly male veterans, higher levels of erythrocyte sedimentation rate and C-reactive protein were associated with increased risk of heart attack and stroke, and higher levels of HDL-C were inversely associated with heart attack and stroke.

Addressing stroke risk factors in black and white Americans: Findings from the National Health and Nutrition Examination Survey, 2009-2010.
The authors examined racial differences in risk factors being addressed among stroke survivors and those at risk for stroke. They found that addressed hypertension and hyperlipidemia in stroke-naïve participants were significantly lower in blacks than in whites. They concluded that a better understanding of this information is critical to preventing stroke and other vascular diseases.

Geographic access to acute stroke care in the United States.
In this article the authors describe access of the US population to all facilities that actually provide intravenous recombinant tissue-type plasminogen activator (r-tPA) or endovascular therapy for acute ischemic stroke. The investigators concluded that more than half of the US population has geographic access to hospitals that actually deliver acute stroke care but treatment rates remain low.

Investigating the utility of previously developed prediction scores in acute ischemic stroke patients in the stroke belt.
The researchers compared several scoring systems among patients receiving systemic and endovascular treatments. They concluded that their study demonstrated that although highly predictive of outcome in the original study design treatment groups, prediction scores may not generalize to all patient samples, highlighting the importance of validating prediction scores in diverse samples.

Over-the-counter and prescription sleep medication and incident stroke: the REasons for Geographic and Racial Differences in Stroke study.
The authors investigated the relation between sleep medication use and incident stroke. At the sleep assessment, 9.6% of the participants used prescription sleep medication and 11.1% used over-the-counter sleep aids. Over an average follow-up of 3.3 ± 1.0 years, 297 stroke events occurred. The authors found that over-the-counter sleep medication use was associated with increased risk of incident stroke; however, there was no significant association with prescription sleep medications. They concluded that over-the-counter sleep medication use may independently increase the risk of stroke beyond other risk factors in middle-aged to older individuals with no history of stroke.

Safety of intravenous tissue plasminogen activator administration with computed tomography evidence of prior infarction.
The researchers sought to determine if the presence of a previous stroke on pretreatment computed tomography (CT) is a predictor of hemorrhagic complications and functional outcomes after the administration of intravenous (IV) tissue plasminogen activator (tPA). Their data suggest that a prior stroke on CT should not be viewed as a reason to withhold this treatment unless it occurred within the last 3 months.

Validity of claims-based stroke algorithms in contemporary Medicare data: reasons for geographic and racial differences in stroke (REGARDS) study linked with medicare claims.
The researchers assessed the validity of diagnostic coding algorithms for identifying stroke in the Medicare population by linking data from the REasons for Geographic And Racial Differences in Stroke (REGARDS) Study to Medicare claims. They found that claims-based algorithms to identify stroke in a contemporary Medicare cohort had high positive predictive value and specificity, supporting their use as outcomes for etiologic and comparative effectiveness studies in similar populations.

Missed diagnosis of stroke in the emergency department: a cross-sectional analysis of a large population-based sample.
The authors sought to estimate the frequency of missed stroke and examine associations with patient, emergency department (ED), and hospital characteristics. They estimated 15,000-165,000 misdiagnosed cerebrovascular events annually in US EDs, disproportionately presenting with headache or dizziness. They recommended that physicians evaluating these symptoms be particularly attuned to the possibility of stroke in younger, female, and non-White patients.

One-year all-cause mortality after stroke: a prediction model.
Using data from Department of Veterans Affairs (VA) national databases, the researchers present and internally validate a 1-year all-cause mortality prediction index after hospitalization for acute stroke. They conclude that a simple index using readily available data that stratifies stroke patients at the time of discharge according to low, moderate, high, and highest likelihood of all-cause 1-year mortality is feasible.

Predictors of systemic inflammatory response syndrome in ischemic stroke undergoing systemic thrombolysis with intravenous tissue plasminogen activator.
This study investigated predictors of systemic inflammatory response syndrome (SIRS) in acute ischemic stroke (AIS) patients treated with intravenous (IV) tissue plasminogen activator (tPA). The investigators indicated that in their sample of IV tPA-treated AIS patients, clinical and laboratory characteristics available on presentation were able to identify patients likely to develop SIRS during their acute hospitalization.

Racial and gender differences in stroke severity, outcomes, and treatment in patients with acute ischemic stroke.
This study sought to determine the association of race and gender on initial stroke severity, thrombolysis, and functional outcome after acute ischemic stroke (AIS). The investigators concluded that race and gender were not significantly associated with short-term outcome, although black women were significantly less likely to be treated with tissue plasminogen activator (tPA). Black women had more tPA exclusions than any other group. The primary reason for tPA exclusion in this study was not arriving within 3 hours of stroke symptom onset.

The association between socioeconomic status and disability after stroke: findings from the Adherence eValuation After Ischemic stroke Longitudinal (AVAIL) registry.
The authors examined the association of three indicators of SES--educational attainment, working status, and perceived adequacy of household income--with disability 3-months following an acute ischemic stroke. They found that 58% of the Adherence eValuation After Ischemic stroke--Longitudinal study patients had a high school or less education, 61% were not working, and 27% perceived their household income as inadequate prior to their stroke. Thirty five percent of patients were disabled at 3-months. They concluded that, in this cohort of stroke survivors, socioeconomic status was associated with disability following acute ischemic stroke.
