States are justifying their bans of transgender health care on a 388-page report called the Cass Review. Supreme Court justices have invoked it.

Today, in @nejm.org, Craig Konnoth and I conclude the report is unsound because it departs from standards in medical law, policy, and practice. 🧵(1/12)

Preach, @jessicaclarke.bsky.social : "contrary to the claims of its proponents, formalism in equality law fails to ensure predictable results, does not meaningfully constrain judicial decisionmaking, and detracts from judicial accountability."

Protecting the nation’s public health demands data, whether it be new measles cases, a surge in ER visits, or shifting patterns in obesity. The most recent job cuts at the CDC threaten the mostly unseen foundation of that research enterprise.

Reshma Ramachandran “said the sequence of events is the antithesis of how the FDA is supposed to function.

“What we’re seeing here is, ‘We believe this and we’re going to find the evidence to support that’ …That’s just inherently wrong in terms of how a scientific agency like the FDA operates.”

Thrilled that my new piece with @drsinhaesq.bsky.social is out. We review different funding models for research and stress the importance of public funding for two reasons: (1) It can support non-profit-driven research, and (2) It can serve as a bulwark against corporate influence over science.

Indicting political opponents & critics because they are political opponents & critics is terrifying.

It's completely inconsistent with the rule of law & democracy.

It should scare everyone - and (hopefully) will get people to realize that we all need to stand against this.
