This is petty, cruel and shows the bizarre priorities of NZ First.

However, Health NZ can still be inclusive and technically obey this jammy little demand by jammy little people. Here’s my comms person take 🧵

Coalition directs Health NZ to stop saying 'pregnant people'

Yes, #Tuberculosis (TB) is curable!

TB is treated with antibiotics taken daily for 4–6 months. ⚠️ Stopping treatment early can lead to drug-resistant TB.

Funding cuts & rising drug resistance put the most vulnerable at risk. Sustained support is crucial to #EndTB 👉 bit.ly/4ilkK1h #WorldTBDay

Amazing day seeing Hamlet at the Royal Shakespeare Theatre in Stratford-upon-Avon today, not sure if I’m more impressed by the acting or the fact we managed to keep up with what was going on 😅
The stage at the Royal Shakespeare Theatre in Stratford. The stage is shaped like a ship. In the centre of the stage is the shape of a body with the flag of Denmark draped over and two spotlights on the shroud.

I read a lot - let’s be friends on storygraph 🤓📚 (also on goodreads but trying to move away from using it so much)

Also need good book recommendations for 2025 - literary or fantasy/sci-fi fiction, and interesting memoirs or public health related non-fiction!

#WorldAIDSDay
Accidentally timed my listening/reading of And The Band Played On with World AIDS Day. It’s fascinating hearing the scientific side of things and epidemiological investigation, but even more moved by the people who pushed for change and justice early in the epidemic.

December 1st! Same as Christmas music 🎅🏻 you’ll use up all the Christmas spirit too early otherwise!

Hopefully this work provides more context to clinicians and those utilising LFTs to make better decisions and interpretations regarding their use and results

🧵8/8
craigjh4.bsky.social
My final thought, and not one that we picked up on in the paper but from my experience in hospital epi - think about how you are using them, is it really cost effective? Will you PCR anyway? What is the context - is there an outbreak? Could moving a possible case present risk to others?

🧵7/8
craigjh4.bsky.social
The study highlights the importance of prevalence in interpretation. High specificity can still result in low PPV when prevalence is low.These nuances are tricky but vital for interpreting results in different settings.

🧵6/8
craigjh4.bsky.social
Bottom line: Use LFTs to identify highly infectious cases during periods of high prevalence, but not as a standalone diagnostic tool. Negative results require careful interpretation, especially in asymptomatic or low-prevalence settings. Use them wisely, not blindly!

🧵5/8
craigjh4.bsky.social
Negative LFT results are reassuring but not definitive. Sensitivity is only 25.65%, so LFTs miss many PCR positive cases. For high-risk or symptomatic patients, a negative LFT shouldn’t rule out infection.

🧵4/8
craigjh4.bsky.social
High specificity (99.91%) means if you get a positive LFT, it’s likely to be a true positive, however low prevalence (0.43%) pulls the PPV down to ~56%, so only about half of positive LFTs are true positives in this dataset. A reminder: prevalence matters for PPV (and NPV)!

🧵3/8
craigjh4.bsky.social
So what did we find? Firstly, LFTs are highly specific (99.91%) but have low sensitivity (25.65%). So, LFTs rarely give false positives, but they miss many true positives.

Fantastic keynote by @nisreenalwan.bsky.social at the UK Public Health Science Conference @ukphsci.bsky.social .
Lots of thoughts for me as an epidemiologist about how we define cases and the harm that unconsidered ‘objectivity’ can have in our work.
Dr Nisreen Alwan presenting at a conference discussing ‘health inequity, epidemic injustice and the claim of objectivity’, in front of a room full of people. 
Dr Alwan is stood next to a screen which says: 
“Scrutinise the claim of objectivity in public health research. 
De-stigmatise ‘self-reporting’. It maybe the best way to measure inequity
Let's not inflict epistemic injustice in the name of rigour.”

Excited to be at the UK Public Health Science Conference, really looking forward to the many talks and posters focusing on inequalities. @ukphsci.bsky.social #UKPHSci #EpiSky

If you haven’t seen this graphic on avoiding gender bias, read it. Ref letters are broadly biased in both major and seemingly tiny ways. The bias is avoidable once you’re aware.
