OBJECTIVE To study whether traditionally vulnerable populations have worse geographic access to trauma centers. DESIGN A cross-sectional analysis using data from the American Hospital Association Annual Survey from 2005 linked with zip code-level data from the US Census. We used a multinomial logit model to examine the odds of having difficult as opposed to easy access to trauma centers for a...
The aim of this review was to compile published data on factor V 1691 G-A alteration in a healthy Turkish population and also to stimulate the reporting of unpublished data, in order to create a map for factor V Leiden (FVL) in Turkey. From a total of 4276 healthy individuals from 26 different centers of Turkey, 345 FVL carriers (7.9%) were determined. FVL was strikingly high among newborns fro...
Coherent population trapping is demonstrated in single nitrogen-vacancy centers in diamond under optical excitation. For sufficient excitation power, the fluorescence intensity drops almost to the background level when the laser modulation frequency matches the 2.88 GHz splitting of the ground states. The results are well described theoretically by a four-level model, allowing the relative tran...
This landmark study [9] – somewhat Twainian at first glance – sets the stage for future microsurgery in cerebral aneurysms and SAH. The ISAT Study does not nail microsurgery – it will nail microsurgery in low case load neurosurgical centers and in inexperienced hands. In future neurovascular centers, exovascular and endovascular surgeons are forced to support each other by having the full respo...
Background and purpose : Serological studies revealed that toxoplasmosis has world wide distribution. Ït is a zoonosis and humans are infected through contact with infected animal, consuming infected food and congenital infection. Due to the different ways of transmission, prevalence of infection may vary between different groups of people. This study was carried out to determine the prevalen...
introduction: despite advances in science and technology, still some natural hazards such as earthquakes cannot be predicted accurately. however, with appropriate knowledge, accurate planning and necessary predictions, we can decrease the mortality and financial losses of such disasters. therefore, attitude and preparedness of healthcare managers toward earthquake can have an important role in ...
