          Abstract

          ABSTRACT The ‘Time is Brain” concept has been a major focus in the World Stroke Awareness Campaign. Objective We describe our experience with a Hackathon (junction of hack+marathon), a 24 hour event of innovation- and technology-based project development, focused around detecting stroke. Method The Hackathon was held during a Brazilian Student’s union (BRASA) congress involving students from engineering and other technological disciplines. Results Four teamscompleted the 24-hour challenge; two teams opted the stroke challenge. One team proposed improving detection using a mobile sensor Fit-Bit combined with a smart-phone to contact emergency dispatch. The other team developed a game, in which kids would play a role as a neurologist; to diagnosis stroke with objective to increase awareness. Conclusion Hackathons can focus attention on innovation and improvement opportunities to support the World Stroke Campaign, as well as other campaigns to raise awareness for other health or social problems.

          RESUMO O conceito ‘Tempo é Cérebro “tem sido um grande foco na Campanha Mundial de conscientização sobre AVC. Objetivo Nós descrevemos experiência com Hackathon (junção das palavras hack+marathon) , um evento de 24 horas voltado a desenvolvimento de inovação tecnológica, centrada em torno de detecção de AVC. Método O Hackathon aconteceu durante o congresso da Associação de Estudante Brasileiros no Exterior (BRASA), envolvendo estudantes de engenharia e disciplinas tecnológicas. Resultados Quatro equipes completaram o desafio, duas optaram pelo desafio sobre AVC, uma propôs a detecção usando um sensor Fit-Bit e um telefone móvel para detecção e contato com a emergência. A outra equipe desenvolveu um jogo para as crianças detectarem AVC. Conclusão Hackathon pode focar a atenção em inovações e oportunidades de melhorias como um adicional a Campanha Mundial contra AVC, bem como em outras campanhas de conscientização para outras doenças ou problemas sociais.

          The "golden hour" and acute brain ischemia: presenting features and lytic therapy in >30,000 patients arriving within 60 minutes of stroke onset.

          The benefit of intravenous thrombolytic therapy in acute brain ischemia is strongly time dependent. The Get With the Guidelines-Stroke database was analyzed to characterize ischemic stroke patients arriving at hospital Emergency Departments within 60 minutes of the last known well time from April 1, 2003, to December 30, 2007. During the 4.75-year study period, among 253 148 ischemic stroke patients arriving directly by ambulance or private vehicle at 905 hospital Emergency Departments, 106 924 (42.2%) had documented, exact last known well times. Onset to door time was 180 minutes in 42 846 (40.1%). Features most strongly distinguishing the patients arriving at 180 minutes were greater stroke severity (median National Institutes of Health Stroke Scale score, 8.0 vs 6.0 vs 4.0, P<0.0001) and more frequent arrival by ambulance (79.0%. vs 72.2% vs 55.0%, P<0.0001). Compared with patients arriving at 61 to 180 minute, "golden hour" patients received intravenous thrombolytic therapy more frequently (27.1% vs 12.9%; odds ratio=2.51; 95% CI, 2.41-2.61; P<0.0001), but door-to-needle time was longer (mean, 90.6 vs 76.7 minutes, P<0.0001).

            Cuffless differential blood pressure estimation using smart phones.

            Smart phones today have become increasingly popular with the general public for their diverse functionalities such as navigation, social networking, and multimedia facilities. These phones are equipped with high-end processors, high-resolution cameras, and built-in sensors such as accelerometer, orientation-sensor, and light-sensor. According to comScore survey, 26.2% of U.S. adults use smart phones in their daily lives. Motivated by this statistic and the diverse capability of smart phones, we focus on utilizing them for biomedical applications. We present a new application of the smart phone with its built-in camera and microphone replacing the traditional stethoscope and cuff-based measurement technique, to quantify vital signs such as heart rate and blood pressure. We propose two differential blood pressure estimating techniques using the heartbeat and pulse data. The first method uses two smart phones whereas the second method replaces one of the phones with a customized external microphone. We estimate the systolic and diastolic pressure in the two techniques by computing the pulse pressure and the stroke volume from the data recorded. By comparing the estimated blood pressure values with those measured using a commercial blood pressure meter, we obtained encouraging results of 95-100% accuracy.

              Translation of the ‘time is brain’ concept into clinical practice: focus on prehospital stroke management

              Acute stroke is one of the main causes of death and chronic disability. Thrombolysis with recombinant tissue plasminogen activator within the first hours after onset of symptoms is an effective therapeutic option for ischemic stroke. However, fewer than 2% to 7% of patients receive this treatment, primarily because most patients reach the hospital too late for the initiation of successful therapy. Several measures can reduce detrimental delay until treatment. It is of importance to use continual public awareness campaigns to reduce delays in patients' alarm of emergency medical services. Further relevant measures are repetitive education of emergency medical services teams to ensure the systematic use of scales designed for recognition of stroke symptoms and the proper triage of patients to stroke centers. A most important time-saving measure is prenotification of the receiving hospital by the emergency medical services team. In the future, treatment already at the emergency site may allow more than a small minority of patients to benefit from available treatment.
