First project presentation at the ESRS Scientific Congresses.

First project presentation at the ESRS Scientific Congresses from Task 121The ESRS holds annual conferences relating to sleep research and medicine The biannual ESRS Congress is the premier scientific congress in Europe relating to sleep research The Sleep and Breathing Congress is a biannual conference held jointly with ERS that is especially focused on education and continuing professional development These events provide the optimum opportunity to present original data arising from research performed in the various WPs of SLEEP REVOLUTION

Translation to different languages

Translation to different languages from Task 74All applicable text and functions in the DMP as seen by healthcare professionals and research staff will be in English A part of the development strategy of the DMP will make the text easily translated to other languages The translation aspect will therefore be included from the start and translating the DMP to a new language will include the manual labour of working with structured files However for the research subjectpatient relevant text and functions in the DMP will need to be translated into the respective language of different countries participating in WP810 This includes the PROMs in the European Sleep Questionnaire and electronic sleep diary NEH which require translation with the assistance of experienced translators The visualizations of data from the wearables will need some translations for each country which this task will also cover If needed text and functions in relation to the mobile application program by SKH objective daytime testing wearables Withings and ES sleep studies NOX and overall platform will also be translated This may however not be needed in all countries depending on the English proficiency of the population eg not needed in Iceland and we will assess which languages are needed as a part of this task
