These findings support public health initiates to increase early presentation and shorten door-to-needle times in patients arriving within the golden hour.Ĭonflicts of Interest/Disclosures: Dr Saver serves as a member of the Get With the Guidelines Science Subcommittee, as a scientific consultant regarding trial design and conduct to CoAxia, Concentric Medical, Talecris, and Ev3 (all modest) received lecture honoraria from Ferrer and Boehringer Ingelheim (modest) was an unpaid investigator in a multicenter prevention trial sponsored by Boehringer Ingelheim has declined consulting/honoraria monies from Genentech since 2002 is an employee of the University of California, which holds a patent on retriever devices for stroke.Är. A door-to-needle time of <0.0001), but door-to-needle time was longer (mean, 90.6 vs 76.7 minutes, P<0.0001). 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%. Onset to door time was 180 minutes in 42 846 (40.1%). 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.Äuring 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. They are electrically charged particles from solar winds that meet oxygen and nitrogen atoms in our atmosphere and convert their energy into light.The benefit of intravenous thrombolytic therapy in acute brain ischemia is strongly time dependent. By the way, the northern lights do not have much to do with this. This then provides for a rather bluish glow. Although these particles are still tiny, they are now larger than the wavelength of light. In winter, on the other hand, the atmosphere contains many more ice crystals and water droplets, on which the light refracts differently. The blue component is thereby reduced to such an extent that only long-wave rays remain, which are known to us as the evening glow. This causes an unusually long path of the light rays through the atmosphere and thus also a strong reflection of the light at gas molecules, at which the light refracts. The twilight phase is then not only longer than usual, but the sun's rays fall at a particularly oblique angle. "Golden hours" in summer The famous golden, deep red and often violet sunsets occur mainly in midsummer due to the elliptical orbit of the sun. But if you leave the brightly lit cities, you can see a blue glimmer on the northwestern horizon even deep in the night. In midsummer, the sun sets in the southern provinces late, but definitely. In the areas further south, this is much less noticeable. In winter, on the other hand, it remains dark there for days on end. This effect is known mainly as the midnight sun. There, it does not get dark at all for several days in midsummer. The northernmost and only very sparsely populated part of the country is Swedish Lapland and lies above the Arctic Circle. Thus, these effects are felt very differently in the elongated country. However, Sweden has a considerable north-south extension of over 1500 km. In winter it is the other way around and days are so short that many inhabitants can hardly or do not want to adjust to it. In summer, the sun is so far north that it hardly gets dark, especially in June and July. 24 hours day and night As a highly northern country, Sweden is famous for its extremely long days in summer and on the other hand very short days in winter.
