Mark Tully was a giant among journalists and the greatest Indophile of his generation. He was also a uniquely warm, generous, gentle, kind and helpful man, at whose feet I was honoured to sit for many years as he patiently explained the subtleties & nuances of India. As the voice of BBC India he was irreplaceable, a man prepared to stand up to power and to tell the truth, however uncomfortable. Both privately and professionally, he will be much, much missed.

Looks like a robust RCT in moderate/severe colitis well done m. Trouble is there are so many different tapering regimens-the findings feel right when I think of my clinical practice. I give 40mg pred 2/52 then reduce 5mg/wk. What do others do?

70 years ago today, Rosa Parks took a seat and started a revolution. By refusing to give up her seat to a white passenger in Montgomery, Alabama, Parks ignited the Civil Rights movement.
RETWEET to honor her historic legacy! 💙

5 medical breakthroughs this week (🧵)
1. A pill to prevent dengue
Tested in a human challenge trial, Mosnodenvir was very effective to prevent dengue infection
This still needs to be tested in the field, but it could add to the 3 licensed vaccines – and prove very useful as dengue territory expands into Europe and the US...

For decades I’ve been obsessed by science.
It's therefore unbelievable to me to be a @Clarivate #HighlyCited2025
Nutrition and dietetics has been amazing to me! The interaction of science, health and food and caring that good nutrition is a human right

🚨 Thanks to @lukelikeslivers @bhmullish @heatherilewis @salihacooks
for this fantastic article giving clinicians a practical approach to nutrition in cirrhosis 👏
The 🔑 messages are:
1️⃣ Malnutriton and sarcopaenia are common and associated with worse outcomes
2️⃣ Patients should eat 3-5 meals a day with a late evening snack
3️⃣ Micronutrient deficiencies and osteoperosis should be screened for
4️⃣ A high protein diet can protect against HE

5 science breakthroughs this week (🧵)
1. Lupus remission with cell therapy
18 patients with longstanding, treatment-resistant lupus were treated with B cell-depleting natural killer cells (CD19 CAR NK-cells)
There results were pretty amazing: every patient was able to stop conventional immunosuppressants and taper steroids; 13/18 had lupus remission (‘DORIS’)
This approach seems to be roughly as effective as using CAR-T cells — with a gentler safety profile

Snapshot of my lecture @gastromx on Diet in Inflammatory Bowel Disease
#ECCO Consensus on Diet in IBD, statement 2:
All people with IBD should have access to a dietitian with experience in IBD
I know we are a long way from achieving this.
But it starts here!
