Studies of sleep duration in relation to specific types of stroke are scarce. Moreover, the results are inconclusive and causality remains unclear. Our objective was to investigate whether sleep duration is associated with risk of stroke and its types using observational and Mendelian randomization designs. ⋯ In a prospective study, long sleep duration was associated with increased risk of total and ischemic stroke, whereas short sleep was linked to increased risk of intracerebral hemorrhage. However, the Mendelian randomization analysis did not show a significant detrimental effect of short or long sleep duration on the risk of total stroke or stroke types.

Enlarged perivascular spaces (EPVS) are considered subclinical markers of small vessel disease, associated with increased risk of stroke and dementia. Increasing evidence links chronic kidney disease (CKD) to small vessel disease. We explored the relationship between CKD and EPVS burden and the influence of racial group in this relation. ⋯ CKD was more prevalent in our sample of patients with stroke with severe EPVS in the centrum semiovale. The relation differed when stratified by racial group and brain topography. Further studies are needed to confirm that CKD may relate differently to subclinical measures of small vessel disease according to race.

We write this article amid a global pandemic and a heightened awareness of the underlying structural racism in the United States, unmasked by the recent killing of George Floyd and multiple other unarmed Black Americans (Spring 2020). Our purpose is to highlight the role of social determinants of health (SDOH) on stroke disparities, to inspire dialogue, to encourage research to deepen our understanding of the mechanism by which SDOH impact stroke outcomes, and to develop strategies to address SDOH and reduce stroke racial/ethnic disparities. ⋯ These approaches include (1) building on prior work; (2) enhancing our understanding of populations and subpopulations, including intersectionality, of people who experience stroke disparities; (3) prioritizing populations and points along the stroke care continuum when racial/ethnic disparities are most prominent; (4) understanding how SDOH impact stroke disparities in order to test SDOH interventions that contribute to the disparity; (5) partnering with communities; and (6) exploring technological innovations. By building on the prior work and expanding efforts to address SDOH, we believe that stroke disparities can be reduced.

Systemic racism is a public health crisis. Systemic racism and racial/ethnic injustice produce racial/ethnic disparities in health care and health. Substantial racial/ethnic disparities in stroke care and health exist and result predominantly from unequal treatment. ⋯ It reviews the social determinants of health and the determinants of racial/ethnic disparities in care. It provides a focused summary of selected interventions aimed at reducing stroke risk factors, increasing awareness of stroke symptoms, and improving access to care for stroke because these interventions hold the promise of reducing racial/ethnic disparities in stroke death rates. It also discusses knowledge gaps and future directions.

Mechanical Thrombectomy in Medium Vessel Occlusions: Blind Exchange With Mini-Pinning Technique Versus Mini Stent Retriever Alone.
Mechanical thrombectomy techniques for intracranial medium vessel occlusions (MeVOs) have evolved in recent years, although the optimal approach is still unclear. The aim of this study was to investigate the effectiveness and safety of mechanical thrombectomy in MeVOs using mini (0.017 inches microcatheter compatible) stent retrievers combined with low-profile (0.035 inches distal inner diameter) distal aspiration catheters through the blind exchange/mini-pinning (BEMP) technique compared with mini stent retrievers alone. ⋯ In the setting of MeVOs, the BEMP technique may lead to higher rates of the first-pass recanalization and a lower incidence of symptomatic intracranial hemorrhage than mini stent retrievers alone.
