Today, NICE have given approval for the life-changing #cysticfibrosis modulator drugs to be made available on the NHS in England. This follows many years of campaigning by Cystic Fibrosis Trust and people right across the CF community. ow.ly/XGMs50SmgJR

Interested in #cysticfibrosis gut microbiome? Our latest study shows gut microbiota of people with #CF on #kaftrio becomes more like those of healthy partcipants with time But not quite Check out findings of our GIFT-CF paper trilogy⤵️ @RyanJosephMarsh @AlanRSmyth @DWRivett

Prof Smyth and colleagues have a 'gut' feeling about the importance of understanding bugs in the intestines to better treat gut symptoms of CF. We wanted to remind you of his research in #WorldMicrobiome week. (1/2) cysticfibrosis.org.uk/news/t…

The burden of #cysticfibrosis in a single sobering image. #CFWeek2023 #CF @cftrust
Rach Norcott@racheyrooney15 Jun 2023
This is what having CF looks like daily. It may be mostly invisible to other people (until you hear/see us cough 😳) but it’s a tough full time battle. This is also what CF combined with a heart attack and stroke looks like, thank goodness for pill organisers! #CFWeek @cftrust 💜

A lovely highlight by the @cftrust on our very own @RyanJosephMarsh and the work he’ll be getting stuck into @NorthumbriaUni
Cystic Fibrosis Trust@cftrust5 Jun 2023
We hear the latest in our series of 'researcher profiles' from Ryan, one of our incredible researchers & scientists. Ryan is working within the Trust-funded GRAMPUS SRC, aiming to establish the causes of gut symptoms in people with CF. Read more here - cysticfibrosis.org.uk/news/i…

Last night myself and @RyanJosephMarsh took part in the @BhamSSN "Dive into Science" talks. We got fantastic engagement from the students, some really insightful questions were asked and hopefully we inspired some to take up #microbiology as a career! #cysticfibrosis #microbiome
