 Good morning all. Welcome to the MSF Scientific Day. Sorry for the abrupt start, but I just wanted to remind you that actually this is not about a day where there's a few people in one centre in Europe talking about a few studies with a little bit of results, but this is a chance for MSF and a wider global community to talk about where we've done well and where we've fallen far short of what we should do in our programs. This is a day where we get to look at evidence that we've gathered within our programs and debate what it means for improving the work that we do and how we can bring more attention to the people and populations who have such great needs that continue to not be met, both medically and politically. We are going to be keeping quite strictly to time but there will be a lot of opportunity for debate. That debate will happen both in the auditorium but also with questions coming in from the online audience. We already had a photo sent in from Monash in Melbourne, Australia, where actually a group of people is sitting watching the event but they've gone to the effort of printing out all of the posters so that they can have their own experience of this day. But it's not just there we've had tweets coming in from the team in Pakistan. We also have this year not just one day but it's four days around innovation and research. So tomorrow's day you'll hear more about is the innovation day. Today is focused more on MSF scientific research but there's also our regional events happening in the next couple of weeks in southern African region and also in India because what we're looking for is a conference without borders where the results get debated and have an impact where they are most needed. I have a couple of housekeeping points. Firstly, if there happens to be a fire alarm I have to mention this for those in the auditorium it means heading out turning left and turning left as you come out here and gathering at Cavendish Square and we'll then be able to work out whether it's a real alert or what we need to do from there. For those on the online audience that's a chance perhaps to gather a coffee and follow the Twitter stream to see what's going on. Hopefully that won't happen. The toilets for those in the auditorium are in the central atrium down the stairs. Can I ask you during the day please to come back slightly early in the breaks. You'll have plenty of time for breaks and discussion but it's important that you come back on time so that we can stay on time. Last year we managed to have people watching from 115 countries. There was at least 5,200 unique logins to watch this event but that in and of itself those numbers don't mean anything if the research we do doesn't lead to impact and change and improvement and that's where I want us to be debating what we do today. For the first time this year we're trying live French translation so for those who prefer to follow online in French that will be available as well.
