🆕 In a new piece in @bmj.com, @jonshaffer.bsky.social & I argue that the powerful physicians who lead federal agencies—e.g., the NIH & FDA—should be RESISTING Trump & RFK Jr’s damaging health policies

I saw her at a recent event in London promoting this book and I couldn’t agree more - she has a wicked sense of humour (and justice) that made me feel I could listen to her stories and insights forever.

Comprehensive sexual and reproductive health and rights is inherently social and political.

Yet the current funding environment sidelines this reality, privileging what's apolitical, say @khosla.bsky.social @pascaleallotey.bsky.social Sofia Gruskin #SRHR #HumanRightsDay

I hear you. I sure as heck would not ask my GP about sports medicine or my performance goals. For health and fitness, social media is king but so too do we need more scrutiny of claims & financial COIs, more responsibility from platforms & more sophistication in how we define problem & solutions

25 no response out of 30 requests to review!

Drives me mad this selfish behaviour, which I also see as a journal editor. And it's almost always established folk with secure jobs, not least those endlessly brandishing their right-on-ness on social media

Mark Fabian @markfabian.bsky.social · Nov 24

Recently did around 30 requests to ppl who'd published very similar papers to the one I needed reviews for. 3 declines, 25 no response. Please at least decline guys it slows stuff down so much otherwise.

I'm still relatively new to this journal associate editor business, but it already sucks… I've had a paper on my desk for more than a month now:
