Hope for #Strep A #vaccine ... | #Streptococcus | #StrepA | #bacteria | #infection | #immunity | By @sheffielduni.bsky.social via @sciencex.bsky.social

The nasal flu vaccine reduces the risk of strep A infections, a study in the UK suggests, contrary to the claims of antivaxxers: https://www.gov.uk/government/news/nasal-flu-vaccine-may-help-reduce-cases-of-group-a-strep

Over the weekend I published an essay series on a question I've been thinking about for a while: What does AI progress mean for medical progress? It starts with this 500 word piece. If you want more after that, there are 10,000 words of forking paths: blog.jacobtrefethen.com/ai-progress-...

So excited to share what Saloni and I have been up to. Medical innovation is not inevitable. Sometimes breakthroughs take 40 years, thousands of people building on each others’ work & participating in clinical trials. Check out ep 1, and subscribe for more Hard Drugs! harddrugs.worksinprogress.co

NEW EPISODE of HARD DRUGS! “5 hours is too long!” some of you said after our first episode. So our second episode is 20 minutes 🤭 @jacobtref.bsky.social and I explore the world of proteins: how proteins fold into complex shapes, why complexity matters, how crowded and dynamic a cell really is.

LAUNCH DAY 🚀 Today I’m launching a new podcast, Hard Drugs, with Jacob Trefethen (@jacobtref.bsky.social) Our first episode is about lenacapavir — a new HIV drug that blocks infections with an efficacy rate of nearly 100%, and which could completely change the fight against HIV worldwide.

#Lenacapavir: The miracle drug that could end #AIDS. The new #HIV drug blocks infections with an efficacy rate of nearly 100%. The "Hard Drugs" podcast w/ @scientificdiscovery.dev @jacobtref.bsky.social open.spotify.com/episode/4nIj...

Dr A Beaton outlines translational research in Uganda turning screening evidence into a national program (ANUDU) for primary health screening and registry. She shows successful screening of 30k patients, and then of those confirmed 72% successful adherence to treatment w/ registry. #LISSSD25 #IDsky

Dr K Brown speaks about developing and validating an AI model for interpretation of non expert handheld parasternal images for DX of MR for RHD which had good sens (0.82) & spec (0.82) for LMIC setting. Also implementation study found it highly acceptable for staff & patients. #LISSSD25 #RHD

Prof de Silva & Dr Keeley speak on Strep A epi & immunity in the Gambia. 🗝️ Hyperendemicity of Strep A 🗝️ Index infections not explained by household contacts 🗝️ Early life immunity develops <2 y/o 🗝️ Ab response to carriage & infection 🗝️ ?protective immunity from SLO, SpyAD, SpyCEP #LISSSD25 #IDsky

A/Prof Laurens Manning presents a human challenge study looking to define penicillin MIC to prevent strep throat. 💊 ~9ng/mL penicillin (lower then standard threshold 20ng/mL) prevents clinical strep throat and systemic inflammation as measured by CRP. #LISSSD25 #idsky

More cool penicillin data - A/Prof J Bennett presents NZ data for subcut BenPen for RHD/ARF 💉 Penicillin >20ng/mL for 56d & >10ng/mL for 70d 💉 Worked better in ⬆️ BMI 💉 No breakthrough infections 😊 Highly accepted - only 1 pt switched back to IM BenPen #LISSSD25 #idsky

Dr J Hart & team on validating clinical decision rules for strep throat: 🌹 Fiji rule (sore throat & neither coryza or hoarseness) is no better than chance. 🚫 No other algorithm tested is any better! Underscores urgent need for POC diagnostics in these settings. #LISSSD25 #idsky

I said no more #LISSSD25 posts but forgot a major highlight! Most sessions started w/ a patient lived experience video, and you can see them all @ lisssd2025.org/patient-stories Looking after patients during thier illnesses is v. stressful so it's great to hear their experiences when recovered.

Prof M Good from Griffith reports some cool unpub phase I vaccine data from two vaccine candidates (J8/S2 & P*17/S2) 💉 Both protect in 🐁 💉 Induce ab response in🚶‍♂️ 💉 Wanes after 6 months, BUT 💉 Opsonic killing increases after 6m #LISSSD25 #strepA #idsky

PhD cand. J Iwasaki talks about mechanism behind strep throat recurrence. 👅 ~15% strep throat relapse 👅 Relapse strains can persist in ⬆️ [pen] 👅 Intracellular persistence in strep intracell. comm. [SIC] 👅 SICs are L-switch'd to lack cell wall hence recur post Pen Rx #LISSSD25 #clinmicro

I wrote a new piece with Rafael Dib on prioritisation in science funding. How should a grantmaker aiming at health impact pick areas to fund, when science is so hard to predict? We argue you can get pretty far, because today's spending is weird: blog.jacobtrefethen.com/vaccines/

Another AUROC: L Carlton presents a possible ARF biomarker id'd from a series of bead array exp using START cohort samples. Most accurate candidate TRAFIP with AUROC 0.79 solo or upto 0.845 in combo w/ other biomarkers. Coming to a revised-revised Jones criteria? #LISSSD25 #idsky

Enjoying the new GiveWell podcast so far. Two episodes in: givewell.transistor.fm

New blog post going into @seqh2o.bsky.social and team’s inventions — which add the right amount of chlorine to disinfect water at places people collect it — and why we decided to support the work in 2020: www.openphilanthropy.org/research/how...

One of my party facts is that according to polls, Americans believe foreign aid is about 25% of the federal budget and on average that it *should* be about 10%. The actual number is less than 1%. Foreign aid has long been a boogey man of the right, so it's not surprising they're vilifying it now.
