What happened in the US last week that should alarm everyone - that's not about Iran
What happened in the US last week that should alarm everyone - that's not about Iran YouTube video by Professor Christina Pagel

Some of the most important threats to democracy do not make the biggest headlines - especially (and understandable) given the new war in Iran. This 4 min update looks at actions weakening the rule of law, reducing oversight, expanding executive power, and making voting harder.

Rose Hip Syrup? I got a spoon of that AND one of cod liver oil before school on Mondays Wednesdays and Fridays. And look at me now.

Kids can take tablets, so why are we still giving liquid medicines? Liquid medicines are often messy, expensive and hard to give so why do they remain the default?

Time to start giving your kids their medication as tablets instead of liquids? Link to academic paper in article. By @oohgpwales.bsky.social

And so we write to brilliant postgraduate students from Sudan, withdrawing the offers and scholarships they won in open competition with the best in the world. A sad day for the University of Oxford.

The missing voice in the debate over Jeffrey Epstein's death is found in the Epstein files The Epstein files include a never-before-seen interview with the doctor who conducted the autopsy on Jeffrey Epstein.

1/ After examining Epstein's corpse, Baden was convinced he died by homicide.

Baden said he has never seen 3 fractures in a suicidal hanging as a medical examiner for 25 yrs, nor while serving for decades as NY state commission that oversees prison deaths.

A little shameless self promotion here.
Was honoured to be asked to write the environmental health chapter for the MedSci 101 textbook Core Concepts in Health (5th Ed).
It came out last week.
Definitely a stretch for me, something I've never done.

The promise and pitfalls of AI in health | LSHTM There has been considerable hype about the transformative potential of AI across many domains of society. Hetan will consider the promise and pitfalls of AI in health, and how we should think about

Tomorrow I'll be giving the inaugural Nick Black Annual Health Services Research Lecture, taking a look at what AI in health might mean and how we can deal with some of the potential pitfalls. It is at 5.30pm at LSHTM and all are welcome - no registration required

'Nobody Could Have Seen This Coming,' Says Blindfolded Administration The Trump administration can't foresee straight.

All wars create unexpected second and third-order effects. One of the appalling things about the Trump administration is that they don’t seem to have thought through the expected effects either. open.substack.com/pub/danieldr...

I've always fancied myself as a non-sectarian Thought for the Day speaker. Decades ago I got into correspondence with Rabbi Lionel Blue and he agreed we should have some non-religious 'thoughts' in that slot.

Though I do always turn off the recorder at the end and ask them if there’s anything else they want to share! Can often charm them into letting me turn it on again and them saying the gem again

"There is no tooth fairy. Nor is there any formal framework or model or checklist of things to do (or questions to ask) that will take you systematically through everything you need to do to 'implement' a particular piece of evidence in a particular setting"

A slide titled 'A cautionary tale: lgnaz Semmelweis (1818-1865)' and the wording
WHAT intervention or innovation
x HOW Implementation strategies
x Effective implementation
x Enabling context

=OUTCOMES

Semmelweis didn't consider the how-how to get people on board how to change their behaviour, how to address their scepticism
Semmelweis didn't consider the context -how he could have understood and address the prevailing barriers

Barrier
Implementation Science Strategy
Doctors didn't believe in handwashing
Use behavior change models (e g COM B) to target beliefs and norms

No leadership support
Engage hospital leaders as champions

No policy reinforcement
Mandate hand hygiene via hospital regulations

Resistance to new practice
Use audit & feedback to show improved outcomes

Lack of training
Build handwashing into medical education

Don't be like Semmelweis!

And using Semmelweiss as the cautionary tale of how *not* to implement healthcare change. Semmelweiss used to write angry letters to colleagues accusing them of being murderers. πŸ€¦πŸ»β€β™€οΈ

Don’t let mega-constellation-building billionaires steal your night sky Satellites are wonders of modern technology that have improved all of our lives. But having more than a million of them in orbit could destroy our view of the heavens and seriously damage our planet

Elon Musk has already started plans to launch a million satellites.

Yes. A MILLION.

This is a colossally bad idea, and it's not too late to make your voice heard. I explain everything:
