@benkesslen (@techreview) is the latest journalist to jump on the bandwagon of misinformation surrounding pediatric gender medicine.

🧵

technologyreview.com/2022/08/18/105…
Considering how easy it is to fact-check these articles into the ground, you have to wonder how much editorial oversight is being exercised here.

Kesslen claims that ROGD is a fiction and that @LisaLittman1 2018 paper in PLOS One is responsible for a spread of misinformation.
First, Littman has always recognized the limitations of her study. Her goal was to describe what appeared at the time to be a newly emerging clinical cohort of transition-seekers. She called for more research to corroborate the ROGD hypothesis.
PLOS One's decision to temporarily take down Littman's paper was driven by pressure from activists. The real story here is not that the paper was taken down, but that it was republished after a second round of peer review (and not, as Kesslen writes, with a "large correction")!
Since 2018, three types of evidence have made Littman's findings more credible. (1) Data from gender clinics around the world, most notably the U.K., showed that the underlying demographic characteristics of ROGD were very much behind the huge surge in referrals. (Cass Review)
(2) Clinicians working in this specific field noted in peer-reviewed articles that Littman's descriptions align with what they were seeing in their day-to-day work and called for more research on ROGD.

Even the Dutch experts who developed pediatric transition have said the same.

publications.aap.org/pediatrics/art…

Thomas Steensma has said that other countries are "blindly adopting" the Dutch approach (2021)--"blindly," b/c it was not developed for the predominant presentation (ROGD).
(3) A study by Littman in 2021 on detransitioners revealed that some had come to their trans identity through social influences.

How to account for the upsurge in the number of teens showing up for transition, the flip in sex and age ratios since the Dutch studies of the 1990's, increasing regret/detransition, and the high degree of psych co-morbidities? Social contagion is the most plausible hypothesis.
There's a difference between saying "we've proven ROGD" and saying "ROGD is very likely, and given the risks of medicalizing we should refrain from doing so pending further research." Few are saying the former, and so Kesslen is essentially setting up a straw man.
Second, Kesslen's own citations are deeply misleading.

Kesslen, e.g., cites this collection of studies. But some of the studies explicitly warned that no conclusions about causal links could be drawn from their findings.

whatweknow.inequality.cornell.edu/topics/lgbt-eq…
More importantly, I looked at 15 at random, and not one was actually about minors. Further, virtually all were done before 2016, when ROGD emerged as a clinical category of concern.

Seems like a problem for an article on CONTEMPORARY PEDIATRIC gender medicine, no?
Another example: Kesslen cites a study by Kristina Olson from this year showing that 94% children who were "affirmed" in the gender identity persisted in that identity five years later.
But as I've explained, the best and maybe only way to square Olson's findings with all past research on persistence/desistence rates in children is by assuming that social transition is iatrogenic. Olson's paper is evidence AGAINST "affirming" care.

city-journal.org/new-study-cast…
In short, Kesslen cherry-picks studies that (he thinks) help his case and ignores those that weaken it.

Third, Kesslen never once mentions developments in Sweden, Finland, and the U.K., where health authorities have drastically scaled down "affirming" care.
Health authorities in these countries have observed sharp changes in the composition of patient cohorts and expressed worries about ROGD. By now, there is simply no excuse for any journalist writing on this issue to ignore these developments.
Finally, Kesslen resorts to lazy appeals to authority, telling us about how most major US medical organizations support affirming care. He ignores the mounting evidence that these groups have been captured by activists and led astray.

WPATH's entire model of care is premised on a single body of low-n, sample-biased Dutch studies that are of very low quality and have never been replicated.

The Endocrine Society's 2017 guidelines were rated, by itself, as resting on "low" or "very low" quality of evidence.
A subsequent peer review of these guidelines gave WPATH a score of 0/6 and ES 1/6.

NEW: UCSF's (@UCSF @UCSF_IHPS) Dr. Jack Turban (@jack_turban) claimed at @theDPUnion debate that the Cass-related systematic reviews found moderate quality evidence that puberty blockers improve mental health.

In a new article, I explain why this claim is false.

⬇️⬇️⬇️
2/ First, Turban confuses quality of studies with quality of evidence. These are distinct concepts in evidence-based medicine, and any clinician opining on the evidence base of medical treatments should understand the difference.
3/ Quality of studies has to do with risk of bias in research. Quality of evidence has to do with our confidence in the estimate of the effects of an intervention on outcomes of interest.

UCSF's (@UCSF @UCSF_IHPS) Jack Turban (@jack_turban) claims that a new systematic review of the evidence for puberty blockers, published alongside the Cass Review (@thecassreview), finds “moderate quality evidence" for the use of these drugs in youth gender medicine.

⬇️⬇️⬇️
In an upcoming article, I explain how Turban confuses quality of studies with quality of evidence—two very different concepts in evidence-based medicine—and ignores the significance of the scoring tool the authors of the systematic reviews used. 2/
As science journalist Ben Ryan (@benryanwriter) points out, Turban conveniently forgot to disclose to the Dartmouth audience that the new systematic review excluded his own 2020 study on puberty blockers from the final synthesis. 3/

I just read the complaint filed by the ACLU of Ohio (@acluohio) asking a state court for temporary injunction against HB68, the new law that restricts “gender-affirming care" to adults only.

What a mess of a document.

⬇️⬇️⬇️
1. ACLU can’t seem to decide if it’s alleging disparate treatment or disparate impact. These are different theories for why some law or policy may violate civil rights or constitutional provisions.
The ACLU says that “transgender people have obvious, immutable, and distinguishing characteristics that define that class as a discrete group.” HB68 “expressly discriminates against transgender adolescents… based on the incongruence between their sex and gender identity.”

Andrea Long Chu's (@andrealongchu) March 11th cover story for @NYMag has sparked some thoughtful reflection in liberal journalism.

⬇️⬇️⬇️
Chu’s essay is worth reading. It makes the case for unrestricted minor access to hormones and surgeries, ignores everything we know about child and adolescent psychology, and openly states that humans have no obligation to come to terms with reality.
I would argue that what Chu says *should* happen in pediatric medicine *already is* happening, more or less.

The Mary Bridge Children's Gender Health Clinic (@Mary_Bridge), which is part of MultiCare health system (@MultiCareHealth) in Tacoma, Washington, and site of whistleblower Tamara Pietzke, offers kids resources on binding and tucking. /1

⬇️⬇️⬇️
Tucking is the process by which boys push their testicles up into the inguinal canal, use their testicle-free scrotum to wrap their penis, and then secure their wrapped penis within their butt cheeks using methods like compression underwear or tape. /2
The Mary Bridge gender clinic says that tucking is "normal for many identities." It admits, however, that "research on the safety" of this practice, including about harmful side-effects, "is very limited and sparse," and recommends that kids do "[their] own research." /3

With the release of the WPATH Files, it's important to keep in mind that WPATH has been using mainstream medical associations like the Endocrine Society (@TheEndoSociety) to launder its pseudoscientific claims and promote experimental and harmful practices.

A thread.
At least 6 of the 10 authors of the Endocrine Society’s 2017 Clinical Practice Guideline were/are WPATH members. That guideline is still in effect today. Image
Recently, the Endocrine Society decided to convene a new group to update its guidelines. It did so in secret, but last week, I very likely forced the exposure of this initiative.
