@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: @ManhattanInst colleagues @ishapiro @JKetcham91 and I have submitted an amicus brief in support of parents suing the Eau Claire Area School District in Wisconsin over its secret gender transition policy.

This is a "Brandeis brief" on social transition.

⬇️⬇️⬇️
2/ The school district instructed staff that “parents are not entitled to know their kids’ identities [at school]. That knowledge must be earned.”

According to the complaint, a teacher posted a flyer with: “If your parents aren’t accepting of your identity, I’m your mom now.” Image
3/ The school district's policy requires developing a "Student Gender Support Plan" while using the student's given name and actual sex when communicating with parents, thus keeping them in the dark.

1/ This is incredible. In the last 24 hrs, the Biden White House’s lack of message discipline accidentally revealed that its official statements on youth gender medicine are dictated to it by outside transgender activists and pressure groups.

McMaster University's @Real_Yuan24, an expert in evidence-based medicine, makes some important comments about the "values and preferences" component of clinical guidelines, specifically in the context of gender medicine.

Here is a thread with his observations. 🧵
2/ For context, in EBM evidence alone is not enough for the development of clinical guidelines. When moving from evidence to recommendations, clinical practice guideline developers are also supposed to take into account patient "values and preference" (among other things).
3/ The bedrock ethical principle here is respect for patient autonomy. But the risk of leaning too much on V&P is having medicine deteriorate into consumerism. So, the question is how to balance V&P (autonomy) with medical expertise and clinician responsibility.

This statement by @AAPPres of @AmerAcadPeds, in response to the interview with Hilary Cass in the NYT times, is so utterly dishonest. It implies that the AAP's position was articulated in response to state age restriction laws. 1/5 Image
The AAP's policy position was published in 2018--well before age restriction laws were first introduced in the states (2020).



@AbigailShrier's Irreversible Damage, which brought the issue to public attention, also didn't come out until 2020. 2/5publications.aap.org/pediatrics/art…
Here are two key passages from the AAP's 2018 statement, "Ensuring Comprehensive Care": one clearly suggesting that "the available data" support puberty blockers, and another deferring to WPATH SOC-7 and Endo 2017, which the Cass systematic review on guidelines found to be untrustworthy. 3/5Image

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/
