Why acute ischemic stroke patients in the United States use or do not use emergency medical services transport? Findings of an inpatient survey

Patients with acute ischemic stroke (AIS) who use emergency medical services (EMS) receive quicker reperfusion treatment which, in turn, mitigates post-stroke disability. However, nationally only 59% use EMS. ...

In this study, we hypothesize that aging enhances the pro-inflammatory function of neutrophils, directly contributing to the poorer outcomes seen in aging patients. We utilized demographic data and biological specimens from ischemic stroke patients and an experimental mouse model to determine the correlation between age, neutrophil function and stroke outcomes. In ischemic stroke patients, age was associated with increased mortality and morbidity and higher levels of neutrophil-activating cytokines. In mice, aged animals had higher stroke mortality and morbidity, higher levels of neutrophil-activating cytokines and enhance...

AbstractPurposeThis review summarizes the current science underpinning the treatment of patients with ischemic stroke who awaken with stroke symptoms. This large subset of stroke patients has historically been precluded from treatment with disability-limiting reperfusion therapies such as intravenous thrombolysis. Recent advances in neuroimaging have shifted the paradigm of treatment based upon rigid time-based criteria to treatment guided by evidence of salvageable ischemic penumbra on advanced imaging.Recent FindingsSeveral recent randomized controlled trials provide evidence that imaging-guided treatment of wake-up and ...

Abstract An important cause of acquired brain injury in children, pediatric ischemic stroke can cause sequelae across a wide range of cognitive domains, including verbal reasoning and processing speed. As a result, survivors are especially vulnerable to academic difficulties and face unique challenges compared to their peers. Despite this knowledge, pediatric stroke remains an understudied neurological condition, and its impact on school functioning poorly understood. The present clinical study addressed academic outcome in this population using a multifaceted approach. Patients were recruited for participation fr...

Background and Purpose: Inflammation plays a significant role in the pathogenesis of acute ischemic stroke (AIS). The role of β2-microglobulin (β2M) as a potential initiator of the inflammatory response in AIS is unclear. The purpose of this study was to analyze the relationship of serum β2M with the recurrence risk and 3-month outcome of AIS.Methods: A total of 205 patients with AIS were recruited, and their clinical and biochemical characteristics were collected. All patients were followed up for 3 months after stroke onset, and the occurrence of death or major disability at 3 months after onset was the ou...

Conclusion. . With the increase of spinal procedures, it is important to identify patients at risk for having an ischemic stroke and to optimize their comorbidities preoperatively. Patients with intraoperative ischemic stroke carry a higher risk for morbidity and mortality during the index hospitalization. Level of Evidence: 4

In this study, we aim to explore the mechanism by which ANRIL exhibits protective effect. Middle cerebral artery occlusion mouse models were applied and infarction areas were assessed by TTC assay. The expression of ANRIL and miR-199a-5p were determined by qPCR. Oxygen and glucose deprivation treatment was applied to mimic in vitro ischemia injury in N-2a cells. The levels of BCL-2, BAX, MEK, ERK, CAV-1 were determined by western blot. Cell viability were assessed by MTT assay. The direct interaction among miR-199a-5p and ANRIL, miR-199a-5p and CAV-1 were demonstrated by dual Luciferase report assay. ANRIL and miR-199a-5p ...

AbstractStroke is the second leading cause of death and main cause of disability worldwide, but with few effective therapies. Although stem cell-based therapy has been proposed as an exciting regenerative medicine strategy for brain injury, there are limitations. The developed cerebral organoids (COs) represent a promising transplantation source for stroke that remains to be answered. Here, we transplanted COs at 55  days and explored the feasibility in the rat middle cerebral artery occlusion (MCAO) model of stroke. COs transplantation at 6 h or even 24 h after MCAO significantly reduces brain infarct volum...
