Tuberculosis and undernutrition: improving estimates to reinforce the policy imperative
Undernutrition is a key driver of the global tuberculosis epidemic, increasing the risk of people developing tuberculosis disease and of poor outcomes in those who do.1 Each year, WHO publishes estima...

Great to see this published after the hard work in Stockholm and Cape Town! How should we think about aerosol detection of #tuberculosis? Is it a diagnostic test? Could it help us prioritize prevention activities? Much more work to do, but exciting nonetheless @climeresearchgroup.bsky.social @ki.se

So...what would happen to the global TB epidemic if we hypothetically "eliminated" undernutrition? In this preprint, we combined estimates from our new review (doi.org/10.1093/ije/...) with population-specific BMI distributions to find out...(doi.org/10.1101/2025...)

Although several AI algorithms can interpret chest x-rays for TB, we still do not have validated or approved CAD products for children. With @jaseddon.bsky.social and colleagues, we shared our thoughts on how to advance CAD for #pediatricTB:

Impact of puberty on immune responses to Mycobacterium tuberculosis in South African adolescents
As individuals progress through adolescence, their risk of tuberculosis (TB) increases and the type of disease that develops changes, with increasing cavitary formation and parenchymal tissue destruction.

Brilliant work by @cfmcquaid.bsky.social and Matt Saunders!

Their updated analysis— a MOUNTAIN of work— shows that an increase in 1 unit of BMI reduces TB risk by 12.3%.
