Scott Leibowitz, a gender clinician and author of @wpath SOC-8, writing in @medpagetoday makes some pretty astonishing claims about the recently published @HHSGov report on pediatric gender dysphoria.

Here are four examples🧵
Regret and Bans

According to Leibowitz, the report "heavily emphasizes concern for regret to justify its extreme positions supporting gender care bans."

FACT: The report explains that while "proponents and critics alike consider the question of regret as central to the ethics of PMT," in fact "regret alone... is not a valid indicator of whether an intervention is medically justified." Patients can regret justified medical interventions or be satisfied with unjustified ones. See Section 13.4.

The report does not recommend or condemn bans; it explicitly says that it "does not issue legislative or policy recommendations" (p. 10).
Psychotherapy

Leibowitz: "the definition of 'appropriate' psychotherapy [the report] employs is questionable, especially considering the apparent lack of input from experienced clinicians in the field, whose public perspectives are conspicuously absent from the publication."

FACT: the word "apparent" is doing a lot of work here. More importantly, it is ironic for Leibowitz to complain about lack of balance among the report's authors. Leibowitz was co-chair of the Adolescent chapter of WPATH SOC-8, a guideline that was developed with a strictly enforced litmus test: only "affirming" clinicians supportive of medical interventions were invited to participate. The HHS report discusses this issue at length (Section 10.3).
Conflicts of Interest

Leibowitz: "Professionals with decades of direct clinical experience working with youth are paradoxically dismissed as inherently biased."

FACT: Evidence-based medicine recognizes the existence of financial as well as non-financial (e.g., intellectual) conflicts of interest. The latter engender attachment to a specific viewpoint in a way that can bias one's assessment of evidence. WPATH itself claimed to rely on COI management strategies laid out by the National Academy of Medicine and the World Health Organization, both of which would consider Leibowitz's personal involvement in pediatric gender medicine as a COI relevant to guideline development. Note that this does not mean clinicians like Leibowitz should never be involved in developing guidelines, only that their COIs must be declared and managed (which, in the case of SOC-8, they were not). The report explains these issues in 10.3.
Golden Mean Fallacy

Leibowitz favors a "nuanced middle ground" between prohibitionists (ban it all) and affirmers (total deregulation), implicitly putting the HHS report in the former category.

FACT: The report carefully describes the evidence and clinical reasoning for ALL pediatric presentations and medical pathways, including the one/s he believes justify medical interventions. Because Leibowitz does not engage with the report's evaluation of the evidence for the (presumably more cautious) Dutch approach, his claims amount to a golden mean fallacy.
No Substantive Engagement

Like other critics of the HHS report, Leibowitz does not identify any specific claims he believes are false.

Does he disagree with the findings of extant systematic reviews of the evidence, analyzed in the HHS report's umbrella review (Chapters 5-8)?

Does he take issue with the ethical analysis (Chapter 13), which he mischaracterizes (see "Regret" post above)?

Does he dispute the systematic reviews of clinical practice guideline quality (utilizing the AGREE II tool) that found SOC-8 to be unfit for clinical use?

In what sense, exactly, is the report's analysis of psychotherapy (Chapter 14) "questionable"? In its recognition that the evidence in support of psychotherapy for treatment of gender dysphoria is weak? In its explanation for how psychotherapy for common comorbidities is stronger?

🚨Dr. Daniel Shumer of @UMichMedSchool is a prolific expert witness in transgender litigation. He has served as expert witness in “about 15” lawsuits and has been paid around $150,000 over the past 4-5 years.

Shumer has admitted to plagiarism in his expert report.

🧵Image
The admission was made in a deposition on March 5, in the context of litigation (Doe v. Horne) over an Arizona law prohibiting males from competing in female sports.Image
At the beginning of the deposition, the examining lawyer asks Shumer to confirm his sworn attestation that he is the sole author of his expert report.

"I was the sole author of the report," he replies (12:25, 13:1).

🚨The New England Journal of Medicine is one of the most prestigious medical journals in the world.

In a new investigation for @CityJournal, I show how @NEJM has put ideological commitments over scientific rigor and debate on the topic of youth gender medicine.

Thread 🧵 Image
2/ My investigative dive into NEJM’s conduct is based on published documents, unpublished submissions and backdoor communications with journal editors.
3/ NEJM publishes original research as well as Perspective pieces, which are supposed to be scientifically informed opinion pieces that undergo peer review.

NEW: The Deposition of Eli Coleman

For the first two articles in this series, I covered the depositions of @Jack_Turban and Meredithe McNamara.

Today’s article in @CityJournal is all about the chair and lead author of @wpath’s latest “standards of care." 🧵Image
Dr. Eli Coleman, a professor emeritus at @UNM_MEDS and founder of U of M's @Human_Sexuality, which was renamed in his honor, submitted to an 8-hour deposition at the hands of Roger Brooks of @ADFLegal in the context of Boe v. Marshall, the Alabama age restriction lawsuit.Image
Coleman's most important admissions had to do with conflict-of-interest management in the development of SOC-8. More on that in a moment.

One benefit of the new lawsuit against Johanna Olson-Kennedy is that newspapers will have little choice but to report on it, and on her, and will inevitably reveal to the public one of the darkest and most twisted figures in “gender medicine.”

It is truly something to behold.

BREAKING: Johanna Olson-Kennedy, perhaps the top name in pediatric "gender-affirming care" in the U.S., is being sued by a former patient.

@jessesingal reports in @TheEconomist 🧵 Image
JOK does not believe in mental health assessments, Singal reports. "I don't send someone to a therapist when I'm going to start them on insulin," she once explained.

The @ChildrensLA doctor has referred children as young as 12 and 13 for, respectively, hormones and mastectomy.
JOK is also recipient of the largest @NIH grant to study the off-label use of puberty blockers & cross-sex hormones. Recently, the @nytimes revealed that she refused to publish outcome data on puberty blockers, fearing that the unimpressive results would be cited by critics. Image

NEW: Azeen Ghorayshi reports in the @nytimes that prominent gender clinician Johanna Olson-Kennedy of @ChildrensLA has refused to publish data from a study on puberty blockers, fearing that the unimpressive results will be "weaponized" by critics of "gender-affirming care." 🧵 Image
Olson-Kennedy told the Times that the kids didn't improve because their mental health was "in really good shape" at the start of the study.

As Ghorayshi notes, this seems to contradict what Olson-Kennedy et al. reported in 2022 about the study's cohort at baseline. Image
Olson-Kennedy fears the study's results could be cited by critics of pediatric sex "change" in court cases. She doesn't seem to think that, as a medical researcher and clinician, her primary responsibility is to her current and future patients.

Doctors as agents of lawfare. Image
