Background and Purpose— Telemedicine is emerging as a potential timesaving, efficient means for evaluating patients experiencing acute stroke. In areas where local stroke care specialists are not available, telemedicine can link an emergency department physician with specialist in treatment center. This consultation provides opportunity administration of thrombolytic drugs within the short therapeutic time window associated ischemic Here, we describe our center experiences report safe...

When self-tracking encounters clinical practices, the data is reshaped by goals and expertise that exist within a healthcare framework. To uncover these shaping we provided Fitbit Zip step-count sensor to nine patients with Parkinson's disease. Each patient wore for four weeks then returned visit their neurologist. Our analysis focuses on this first after of had been collected. use conversation both talk action makes visible practices engaged in collaborative members 'craft view' toward...

Introduction: Posttraumatic stress disorder (PTSD) has emerged as a mental health barrier that can be experienced by survivors of stroke. PTSD triggered thoughts stroke impacts patient’s ability to optimize their outcome and maintain compliance with secondary prevention. A young adult clinic treating aged 18-50 in an urban setting Maryland implemented standardized practice screen all patients for PTSD. retrospective data analysis was performed determine prevalence the population identify...

<h3>BACKGROUND AND PURPOSE:</h3> Previous studies in acute ischemic stroke have demonstrated the importance of minimizing delays to endovascular treatment and keeping thrombectomy procedural times at &lt;30–60 minutes. The purpose this study was investigate impact on clinical outcomes. <h3>MATERIALS METHODS:</h3> We retrospectively compared 319 patients having undergone according time (&lt;30 minutes, 30–60 &gt;60 minutes) from onset therapy (≤6 or &gt;6 hours). Clinical characteristics with...

Although the US Black population has a higher incidence of stroke compared with White population, few studies have addressed Black-White differences in contribution vascular risk factors to burden ischemic young adults.A population-based case-control study early-onset stroke, ages 15 49 years, was conducted Baltimore-Washington DC region between 1992 and 2007. Risk factor data obtained by in-person interview both cases controls. The prevalence, odds ratio, population-attributable percent...

Abstract Background The use of antithrombotic therapy (anticoagulants and/or antiplatelets) in the setting traumatic cervical arterial dissection (CAD) for prevention stroke remains controversial. This issue is further complicated by frequent co-existence intracranial hemorrhage (ICH) and other injuries, also wide variability treatment due to a lack evidence-based guidance. To address these controversies, registry major Level I trauma center was created. purpose this investigation compare...

Elevated International Normalized Ratio (INR) is a marker of coagulopathy, but its impact on outcomes following mechanical thrombectomy (MT) in patients with stroke unclear. This study investigates the mild INR elevations clinical MT.In this retrospective cohort study, consecutive treated MT were identified from 2015 to 2020 at Comprehensive Stroke Center. Demographic information, past medical history, INR, National Institutes Health Scale score, use tissue plasminogen activator, and last...

Background: Conventional interferon monotherapy fails to achieve virological clearance in most hepatitis C‐infected patients. The use of high‐dose induction regimens may improve the initial virus, while addition ribavirin appears rates sustained response once is achieved. Aim: To compare efficacy and safety re‐treatment with an regimen alpha‐2b, or without ribavirin, chronic C patients who have not responded standard dose monotherapy. Methods: Previous non‐responders (3–5 MU three times...

Background: Mechanical thrombectomy (MT) is the standard of care for acute ischemic stroke caused by large vessel occlusion, but not available at all centers. Transfers between hospitals lead to treatment delays. Transport directly a facility capable MT based on prehospital severity scale score has been recommended, if transportation time less than 30 min. Aims: We hypothesized that an Emergency Medical Services (EMS) routing algorithm stroke, using Los Angeles Motor Scale (LAMS) in field,...
