Nuclear War: A Scenario - Wikipedia

I recently read this book, and couldn’t sleep for weeks - absolutely terrifying. Glad this is being highlighted as a key threat to planetary health.

In the SaDAPT trial with people with #HIV and #tuberculosis symptoms in 🇲🇼🇱🇸, we investigated if antiretroviral therapy should be initiated immediately, or delayed until TB results available. ssrn.com/abstract=523...

Outcomes (incl. IRIS) similar across both arms.

We are excited to share that the new @who.int Consolidated Guidelines - National TB Prevalence Surveys is out now!🎉

👏Our KNCV colleagues, Petra de Haas and Edine Tiemersma, contributed to the development of this valuable resource for #TB care and prevention.

Just saw the presentation at IAS. This is exactly the trial we needed. Previous attempts like SLATE missed the mark but you have done it, congratulations.

Thanks Tom!

Really great plot. And as per other comments, would have fewer groups for the categorical.

In the context of meta-analysis of aggregate data, we had a lot of fun figuring out how to include age as a predictor in this paper www.sciencedirect.com/science/arti...

📢in @lancetgh.bsky.social we show heavy catastrophic health expenditure burden in people with chronic respiratory disease symptoms,Meru #Kenya.🔍 Of 296 adults,26% had #CHE (health costs>10% household expenses),CHE more likely in females & if seeking care accompanied or at sub-county/county hosps.

New study published in @thelancetph.bsky.social finds that from adolescence onwards, men have higher Mycobacterium #Tuberculosis infection rates than women, resulting in higher prevalence of immunoreactivity.

Super stuff @petermacp.bsky.social @lightontb.bsky.social team!

New systematic review led by @hannahrickman.bsky.social shows annual risk of Mycobacterium #tuberculosis conversion in men and women diverges during adolescence and remains higher among men throughout adulthood.

NEW STUDY! 📣

A large global study found men are more likely to be exposed to TB than women.

The reason? Likely social behaviours:
• More time in crowded indoor spaces
• Delays in seeking care

Brilliant analysis that reinforces the need for concerted efforts to address gender-related barriers to TB diagnosis and treatment for men and adolescent boys. Essentially, men are more likely to acquire TB because they are more likely to be exposed to other people (mostly men) with TB.

Figure showing male-to-female prevalence ratio in MTB immunoreactivity

In meta analysis of data from nearly half a million people, we found that men have higher M. #tuberculosis immunoreactivity risk than women.

Likely to be key driver of
sex differences in global tuberculosis morbidity & mortality

The end of tuberculosis that wasn’t In the 1980s, many thought tuberculosis was on the path to elimination. In reality, more were dying from the disease than ever.

Tuberculosis still kills around 1.3 million people every year.

It was once a massive killer in Europe and the US, but not anymore. How did these countries manage to tackle it?

Amid all the bad news in Global Health, perhaps some good news? A first analysis on the risk of false positive diagnoses in community-screening for tuberculosis using Xpert shows our clinic-based data is likely (very) wrong and overestimates false positives by >80%: tinyurl.com/yfecute9.
