I think this came up in a recent FRCA SOE, so might be useful;

ZODIAC trial: For ischemic stroke patients who are awaiting thrombectomy, flat positioning reduced the risk of neuroworsening or death

Premature termination but seems reasonable

Statistically robust results

Best available evidence; should change practice

Results of the #SESARtrial:

Among patients with moderate/severe ARDS, inhaled sedation with sevoflurane resulted in
- fewer ventilator-free days at day 28
- lower 90-day survival
than sedation with propofol.

Is it sad I’ve already named my career defining clinical trial (which someone will probably do before me) with one of those dodgy acronym titles

Mysterious Blobs in Cells Are Changing the Way We Understand Life Tiny specks called biomolecular condensates are leading to a new understanding of the cell

In the cover story of the February issue of @sciam.bsky.social I explain what biomolecular condensates are and why they are transforming cell biology. A short 🧵

Sat in lab meeting recently fairly sure I was the most stupid person in the room. I hear it’s supposed to be a good thing but it was hard work 😮‍💨

Have struggled with ‘me time’ reading recently, so good to hear the writing style is so good. Always a bonus if compliments current work. Good luck with the new work!

Another insightful episode. I love these mostly because they often describe the hiccups and failures along the way, although listening to this Tim is supremely impressive. And yes I did try and fail at astronaut selection 👩‍🚀

Application of cardiac surgery techniques to improve the results of cardiopulmonary resuscitation after cardiac arrest: Controlled automated reperfusion of the whole body Until now, the overall results (survival and neurologic outcome) of cardiopulmonary resuscitation (CPR) after cardiac arrest (CA) have been quite dismal.

A few years ago I posted this thread in the other place, reflecting on my PhD journey whilst prepping for my viva. Thought I should post it here now we are moving to Bluesky. Hopefully it's useful for aspiring researchers!

Reflections on taking time out of clinical training to pursue research: 1/n

Hopefully 1st bit of solo data collection tomorrow 📊
