Many Long COVID trials have reported negative results in 2024 and 2025. In our Comment for @thelancetinfdis.bsky.social we argue that inadequate outcome measures might have played a role. (1/12)

In the second half of the twentieth century, Bayesians began to hold that they had a solution to the problem of induction. What is this solution exactly, what does it tell us about the problem of induction, and does the solution work? You can find out in my new paper!

I’d be grateful if more were written on RFK’s AIDS denialism—important context IMO when we hear him say things like, Long Covid docs are being ignored like docs were ignored in the AIDS crisis. I think he’s dog-whistling alternative therapies that posited lifestyle and not HIV caused AIDS.

This is why pwME get so upset when newcomers to the field don’t engage existing experts. We have lost so, so much time, and critical information, to people who refuse to build on existing knowledge.
They’ve literally been reinventing the wheel for no reason

Every now again it’s useful to repeat advice about accessing papers that are behind a paywall that excludes you. Email the author. My estimate is that 90% of academics are so thrilled that a living, breathing, possibly even reading, person shows interest that they will swiftly send you a copy.

Excellent reporting (featuring a quote from me!) on what happened to the hotly anticipated BC007 trial for Long COVID, which reported negative results despite reports of major improvements from some trial participants. Bad study design could have led to a false negative
German start-up Berlin Cures announced it would not conduct additional research after a failed #LongCOVID clinical trial of novel drug BC 007.
