Despite the presence of neural stem cells and ongoing neurogenesis in some regions adult mammalian brain, neurons are not replaced most brain after injury. With aim to unravel factors contributing failure injured cerebral cortex, we examined expression cell fate determinants acute injuries, such as stab wound or focal ischemia, a model chronic amyloid deposition. Although none neurogenic factors, Pax6, Mash1, Ngn2, was detected parenchyma, observed strong up-regulation bHLH transcription...
Recent case-series of small size implied a pathophysiological association between coronavirus disease 2019 (COVID-19) and severe large-vessel acute ischemic stroke. Given that strokes are typically associated with poor prognosis can be very efficiently treated recanalization techniques, confirmation this putative is urgently warranted in large representative patient cohort to alert stroke clinicians, inform pre- in-hospital pathways. We pooled all consecutive patients hospitalized...
Structural alterations of the cellular prion protein (PrP C ) seem to be core pathogenesis diseases. However, physiological function PrP remains an enigma. Cell culture experiments have indicated that and in particular its N‐terminal octarepeat region together with phosphatidylinositol 3‐kinase (PI3K)/Akt signaling pathways a fundamental involvement neuroprotection oxidative stress reactions. We used wild‐type mice, knockout ( Prnp −/− animals transgenic mice lack (C4/−) subjected them...
Background and Purpose- Posterior circulation stroke (PCS) account for 20% of all ischemic strokes. There is limited evidence whether functional outcome PCS comparable to that anterior (ACS). We aimed analyze 3-month different in ACS. Methods- Patients with acute prospectively enrolled within the Austrian Stroke Unit Registry were stratified by infarct localization according Oxfordshire Community Project Classification. Propensity score matching was used control covariate imbalances match...
<h3>BACKGROUND AND PURPOSE:</h3> In a very limited number of cases, acute migrainous aura may mimic brain infarction.

All examined clinically by 2 neurologists and underwent standard stroke protocol, including PWI. Two...
Background:Comprehensive studies on caregiver burden (CB) of persons caring for dementia patients differ methodologically and show variable results. Objective:Analysis known hypothesized factors CB in home care patients. Methods:Multicenter longitudinal study comprising 585 pe rsons mostly Alzheimer's disease (age median 77.25 years, Mini-Mental State Examination raw score 23) using the Zarit Caregiver Burden Interview (CBI). Known patient-related determinants were studied, such as severity...
Neurogenic dysphagia is common and has no definitive treatment. We assessed whether pharyngeal electrical stimulation (PES) associated with reduced dysphagia.The PHAryngeal for treatment of neurogenic Dysphagia European Registry (PHADER) was a prospective single-arm observational cohort study. Participants were recruited (comprising five groups - stroke not needing ventilation; ventilation acquired; traumatic brain injury; other neurological causes). PES administered once daily three days....
To date, risk assessment of suffering ischemic and hemorrhagic stroke in individuals under oral anticoagulation (OAC) is limited to hospital-based cohorts patients with atrial fibrillation.
Introduction Despite the availability of prevention and therapies stroke, their implementation in clinical practice, even low-cost ones, remains poor. In 2015, European Stroke Organisation (ESO) initiated ESO Enhancing Accelerating Treatment (EAST) program, which aims to improve stroke care quality, primarily Eastern Europe. Here, we describe its methods milestones. Patients The EAST program is using an strategy based on a ‘detecting-understanding-reducing disparities’ conceptual framework:...
Background Chalos et al recently developed the MR PREDICTS@24H model to predict 90 days functional outcomes in ischaemic stroke patients following endovascular treatment (EVT). We aimed validate this real-world situation of admitted a tertiary care hospital. Methods conducted retrospective cohort study including selection adult (≥18 years old) eligible for EVT tretiary center between January 2014 and May 2023. Model performance was assessed using C-statistics discrimination calibration plots...
<h3>Objective:</h3> It is not clear whether risk scores for early stroke recurrence after TIA that have been mainly established in outpatient and emergency department settings are valid on the background of highly specialized unit care. <h3>Methods:</h3> ABCD2 ABCD3-I prospectively documented a cohort patients admitted to Austrian units within 24 hours symptom onset with or minor (NIH Stroke Scale score <4). <h3>Results:</h3> A total 5,237 met inclusion criteria, 3-month follow-up data...
Abstract Transient ischemia has been shown to damage the basal lamina of cerebral microvasculature. Other studies proved statins be beneficial non‐cerebral microvessels. The aim this study was determine whether pravastatin pretreatment ameliorates microvascular following transient ischemia. Using suture model, we subjected 15 rats focal (3 h) and reperfusion (24 h). Rats received (20 mg/kg/day) or saline for 4 weeks prior experiment. outcome determined by a behavior test infarct size....
Background and Purpose— Microplasmin is a recombinant truncated form of human plasmin. It has demonstrated efficacy in experimental animal models stroke tolerability healthy volunteers. We tested the microplasmin patients with acute ischemic stroke. Methods— In multicenter, double-blind, randomized, placebo-controlled Phase II trial, 40 were treated either placebo or active drug between 3 12 hours after symptom onset dose-finding design. Ten received placebo, 6 total dose 2 mg/kg, 4 mg/kg....
Epidemiological studies show that increased physical activity is linked to a lower risk of breast cancer and mortality. As result, can significantly improve patients' quality life (QOL) both during after therapy.Many patients demonstrate decrease in cognitive capacity, referred as the symptom-complex related impairment (CRCI). Most frequently reported impairments are mild moderate deficits processing speed, attention, memory, executive functions. Cognitive symptoms persist for months or even...
In focal cerebral ischemia the plasminogen-plasmin system plays a role in fibrinolysis of vessel-occluding clots and also proteolysis extracellular matrix components, which potentially contributes to brain edema bleeding complications. The authors investigated plasminogen activation after middle artery occlusion with without reperfusion (reperfusion intervals 9 24 hours) rats by histologic zymography compared areas increased structural injury, were detected immunohistochemically. After 3...
Intravenous thrombolysis improves functional outcome in patients with acute stroke and frequencies of r-tPA (recombinant tissue-type plasminogen activator) treatment have been increasing over time. We aimed to assess whether r-tPA-treated improved time investigate the influence clinical variables on outcome.We analyzed data Austrian Stroke Unit Registry from 2006 2019. Favorable was defined as modified Rankin Scale score 0 2. Frequencies 2 were assessed for overall population prespecified...
Background and purpose Blood pressure (BP) variability has been associated with worse neurological outcomes in acute ischaemic stroke (AIS) patients receiving treatment intravenous thrombolysis (IVT).
