@jaynesutherlandtb.bsky.social Nice study but... I'd rather you chose a threshold with NPV of 99% and say X% had TB effectively ruled out. This would help me as a clinician. An NPV of 95% doesn't help, I am going to investigate with sputum etc. #blueintheface academic.oup.com/cid/article/...

Of course paracetamol doesn't cause autism but can the media stop saying 'not treating fever in pregnancy will lead to harm to the baby' without any EVIDENCE to back this up. It's conceivable that treating fever actually causes harm (this is a hypothesis not a statement of fact). #thenewsagents

The Diagnostic Detective asks- should you take paracetamol (acetaminophen) for a fever? Will it help, will it hinder? thediagnosticdetective.substack.com/p/does-parac...

This is why indiscriminate use of CAB/RIL in Africa will be a disaster. INSTI resistance emerged in approximately 40%–70% of individuals experiencing VF. VF is rare in clinical trials (per diems), it will be much higher in standard of care settings in Africa. academic.oup.com/cid/article/...

Conclusion says 'no significant difference' but it was a small study with 11%[95% CI –0·9 to 22·5] ARR. Surely a Bayesian approach would be more informative? I would use steroids in these patients - The Lancet Respiratory Medicine ‪@lancetrespirmed.bsky.social‬ www.thelancet.com/journals/lan...

Can't believe the EMPIRICAL study showing reduced MORTALITY in kids with pneumonia given valganciclovir didn't get an oral! Come on #IAS2025. This is a VERY important finding.

The upcoming NIRVANA study will randomise these folk to valganciclovir or placebo to test safety, with a view to a phase 3 trial powered for mortality.

I hope all attendees at #IAS2025 ask themselves an important question. In these times of austerity, can I put my hand on my heart and say that the resources used to send me here could not be have been better used elsewhere? If yes, happy days enjoy. If no, please reconsider future 'academic' travel.

Can we just accept the maxim that in people with virological suppression, ANY 2 drugs from different classes will be non-inferior to ANY standard regimen? Or can we at least publish these studies in very low impact journals and move on. #HIV #LancetHIV www.thelancet.com/journals/lan...

"Brooke Nichols, an associate professor of global health at Boston University, has estimated that these cuts have already resulted in about 300,000 deaths, most of them of children, and will most likely lead to significantly more by the end of the year."

it boggles the mind that the same people who are absolutely sure that SARS-CoV-2 is a bioweapon are working destroy our ability to perform the exact research that would maximize our preparedness to counter such a bioweapon

I'm sceptical about a wide-spread roll out of Cabotegravir/rilpivirine LA in Africa due to high risk of resistance. However, the look of delight on a 24 yr old vertically transmitted HIV patient when I told her of its existence was quite something to behold. #idsky

Ever wondered what you 'flinch point' probability (Therapeutic Threshold) is for starting TB Rx when no more information is available? In outpatients its likely around 37%. Above that, start Rx, below that, watch and wait. @lutlynen.bsky.social #tuberculosis www.sciencedirect.com/science/arti...

I was given the same advice by a General Practitioner in Oxford. I also won't name him but it was shocking www.bbc.com/news/article...

He has certainly sold himself out in search of a bigger audience and more money. A shame because some of his early stuff was quite good.

Throughout history, four infectious diseases—tuberculosis, smallpox, malaria, and plague—have claimed millions of lives. Tuberculosis has killed an estimated 1 billion people, while smallpox took 300-500 million lives in the 20th century before its eradication in 1980.
