It's free. So if you're looking for a paper to cite but can only read the one in World Psychiatry, you'll cite that one.

Idaho Cut Services for People With Schizophrenia. Then the Deaths Began.

“They realized, well, that was a mistake,” said Sheriff Sam Hulse of Bonneville County, a Republican. “You started seeing deaths occurring in the community. We started seeing the numbers in the crisis system rise. The very thing we told them would happen was beginning to happen.”

What about classification as a means of identifying an appropriate treatment? For instance, the HiTOP distinction of internalizing and externalizing spectra maps pretty well onto the most effective treatments for those types of problems.

A reliable descriptive system is critical for scientific research. It also has the benefit of avoiding the problems that arise when a nosology is wrapped up in etiological theory, like the hopelessness that can accompany statements like “all disorders are disorders of britain circuits”.

This is a clear summary of why good description is so important to science. Many of the discoveries we would like to make—about predictors, causal agents, and outcomes of psychopathology—are obscured by nosologies that have these elements baked in.

National survey of NIH-funded researchers shows precarious state of U.S. science — ‘This is like the Titanic’ A nationwide STAT survey of NIH-funded researchers reveals that, a year after Donald Trump's return to the White House, many scientists are reeling

The people developing the treatment for your cancer diagnosis in 25 years are not ok.

American Science is not ok...and Republicans are letting it happen.

Russets and some older varieties have a nice dry, tart flavor. What's so wrong with that? Why this incessant search for greater sweetness?? *Shakes fist at sky*

We've gone too far w/crispness and sweetness. UMN was so concerned with whether they could, they didn't stop to think whether they should.

White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.

The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. 🧵👇

The Call for Abstracts has been extended until March 2nd, and we're excited about building an engaging scientific program. We hope you'll consider submitting your work, and hope to see you in June!

Approval of new members takes years. The HHS Secretary (RFK Jr) can select members, and these selections would not be subject to the vetting process.

Exclusive: key NIH review panels due to lose all members by the end of 2026 Thirteen of the agency’s advisory councils, which must review grant applications before funding is awarded, are on track to have no voting members.

As things stand today, all NIH institutes will have empty advisory councils by the end of 2026. NIMHHD will have an empty advisory council in 1 month, NIMH in 8 months.

That is gorgeous. Is it your own recipe or can interested followers find it published somewhere?

Completely. I'm not a parent, but I have tremendous sympathy for parents of over-scheduled kids, and parental overwhelm seems like reason enough to back off.

Thanks to my trainees Amna Asim, Yuan Yang, coauthors @toddlencz.bsky.social, @seanclouston.bsky.social and others not on Bsky. And thanks to the @quantitude.bsky.social podcast, whose collider bias episode provided solace and validation in the middle of the peer review process. 6/6

Check out the paper for demonstrations of this effect in simulations and three datasets. We need to understand how PGS perform in clinical settings if they are ever to be useful as predictive markers, which is what we are trying to accomplish with the FEP-GEN consortium. 5/6

Collider bias also skews associations between the BP PGS and clinical outcomes like remission and recovery. The BP PGS is associated with lower odds of remission (OR=0.79) and recovery (OR=0.86) in the general population, but positive (ORs=1.19 and 1.2 but nonsignificant) among cases. 4/6

Selection therefore becomes a collider, and conditioning on the collider (implicit in case-only analyses) attenuates the correlation between the SZ and BP PGS. 3/6
