There's much more in the preprint - a great team effort from @clairecoffey.bsky.social @sritchie73.bsky.social, Lisa Pennells, Angela Wood & @mikeinouye.bsky.social all from @cambridge-ceu.bsky.social!

Clinical statements (AHA, ESC) have suggested that PRS may be most useful as a risk-enhancing factor for those at intermediate risk. We used PRS to reclassify individuals at intermediate risk by QRISK3 and showed improved sensitivity and fairness benefits (particularly for age & sex).

We evaluated PRS in two contexts, as a standalone risk predictor and as a risk-enhancing factor. Given the known performance differences across ancestries, we were surprised to find that the fairness of PRS predictions across ethnicities was equal to or lower other CVD risk factors when used alone.

Algorithmic fairness metrics have made big inroads in the AI/ML fields to investigate model bias. A clever PhD student (@clairecoffey.bsky.social) thought, why don't you see these methods applied to CVD risk prediction or polygenic risk scores?

📣 Latest from the lab: Performance of deep-learning-based approaches to improve polygenic scores www.nature.com/articles/s41...

Its thought deep learning will substantially improve PGS but the reality is MANY have tried but no/little gain has been seen so far. Here we report our negative results.

What a great first day at #HAICON25 - I had a fab time in the poster session chatting about my work on AI for environmental health this afternoon, and I look forward to learning lots more in the next couple of days! @helmholtzai.bsky.social

Healthcare data is vulnerable to biases.

Working with @acceleratescience.bsky.social and @clairecoffey.bsky.social, we are building an open source educational resource hub to mitigate algorithmic bias.

Read the blog post below to find out more!
📢 New blog! Read about @lekaa-shree.bsky.social's work on dataset scarcity & algorithmic bias in AI in healthcare. With collaborators in Cambridge & Uganda, Lekaa has examined challenges & is planning a virtual resources hub to improve bias mitigation strategies.

I’m excited to share that I’ve joined @www.helmholtz-munich.de this week! 😄 Here, I’ll be using machine learning to better understand the relationships between environmental changes, socioeconomic factors, and health - building on my PhD research by integrating algorithmic fairness throughout. 🤓

Happy new year everyone! 💫 I'm pleased to share that I submitted my PhD thesis a couple of weeks back - just in time for the holidays - now to wait for the viva! It’s been an amazing journey and I'm excited for the new year, which marks the start of my next chapter! 🎓
