1/ In his embarrassing interview with Stella O'Malley and Mia Hughes, Gordon Guyatt repeated the claim that the Health and Human Services report on gender medicine used the McMaster reviews to justify the denial of care to transgender people. 2/ This is a misrepresentation of the HHS report, which does not make any policy recommendations. It does present evidence which could be used to justify a ban on pediatric gender medicine but this evidence goes well beyond the systematic reviews.

1/ One aspect of the controversy over @GuyattGH, @segm_ebm and the McMaster systematic reviews which has not been noted is the link with Egale Canada and ongoing litigation over the pediatric gender medicine ban in Alberta. @GuyattGH @segm_ebm 2/ Egale Canada is the plaintiff in an action to block the Alberta legislation restricting medical transition of minors. A judge granted an interim injunction against the implementation of the law, and the government has appealed cbc.ca/news/canada/ca…

A short but pointed thread by another leading figure in evidence based medicine on the extent to which the recent statement @GuyattGH and some of his colleagues on their systematic reviews of gender medicine betrays the core principles he helped to develop. /2

One of the principles of evidence based medicine is avoiding bias through management of conflicts of interest. The methodologists who lead systematic reviews and guideline development are supposed to be neutral on the clinical and policy implications of their work. /3

WPATH can't catch a break. Even though the ACLU agreed to dismiss Boe v Marshall, where it challenged the Alabama law banning medical transition of minors, a federal judge has just ordered that more of the documents WPATH disclosed be made public. /2 Many of the documents produced by WPATH were subject to a protective order and could not be published but the judge ruled that recordings or WPATH and USPATH conferences and panel discussions were not confidential and were not covered by the order. /3

1/ The report of the Quebec Comité de sages sur l'identité de genre is out. It is over 200 pages in French only so it will take me some time to review. The recommendations are modest and often vague but do represented some small progress. Link is in the next Tweet. 2/ The report consists of two volumes and a summary. This is a summary of the summary. The links are on this page:quebec.ca/gouvernement/m…

1/ The Canadian Medical Association is challenging Alberta legislation restricting pediatric medical transition on the grounds that it violates the Charter by restricting physician's freedom of conscience.

https://x.com/globeandmail/status/1927652864450773437

2/ The Alberta law bans puberty blockers, limits cross sex hormones to patients over 18 and surgery to those over 18. It is part of a larger package that covers social transition in schools and sports. justdad7180.substack.com/p/alberta-chal…

1/ The plaintiffs in the challenge to the Alabama law restricting medical transition of minors have agreed to drop the case. Boe v. Marshall has probably done more to undermine the case for WPATH and pediatric gender medicine than any other legal action. 2/ The masterstroke by the Alabama Attorney General was to bring a motion to compel the World Professional Association for Transgender Health to produce the correspondence relating to the creation of its SOC8.

1/ Some good news from the UK. The @Sullivan_Review of data, statistics and research on sex and gender will likely have a wider effect on breaking the destructive hold of gender ideology than the Cass Review.

https://x.com/wesstreeting/status/1902637859649069301

@Sullivan_Review 2/ The review is a comprehensive rejection of the ideas and assumptions behind gender ideology. You can read the full report and an executive summary here. assets.publishing.service.gov.uk gov.uk/government/pub…

1/ The BC College of Nurses and Nurse Midwives (which recently found Amy Hamm (@preta_6) is not getting much love on Google. It has a one star rating and the first review reads, "The staff are very unprofessional and boderline abusive." @preta_6 2/ If you sort the reviews by date, the most recent review (from a month ago) is a five star review but after that the reviews are overwhelmingly negative. Out if 161 reviews I could only find 2 other positive reviews and 10 ratings that were above 1 star.

1/ The Amy Hamm (@preta_6) decision is a defeat for women, free speech, law, science and common sense. It is a fundamental denial of Amy's freedom to advocate for women's sex based rights. I'll try to do a longer analysis but here are some preliminary comments. @preta_6 2/ The decision is 115 pages long, consisting of 85 pages of reasons and a 30 page appendix which discusses specific statements. There will be a further hearing on penalty and costs. You can read the full decision at this link if you can stand it. jccf.ca/wp-content/upl…

1/ If the US Supreme Court strikes down Colorado's law against "conversion therapy" to change gender identity, that would do far more, in the long term, to protect gender dysphoric youth than a simple ban on medical transition of minors.

https://x.com/benryanwriter/status/1899178697485115705

2/ While most conversion therapy laws have exemptions for some form of exploratory therapy, transgender activists promote a narrow interpretation which puts any therapist who questions the assumptions of the gender affirmative care model at risk.

1/ Today's Executive Order is being widely celebrated as a ban on youth transitions. In fact, a total ban is outside of executive power and even the power of Congress, but there is no doubt that medical transition of minors will be significantly limited.
whitehouse.gov/presidential-a… 2/ All federal agencies are ordered to rescind policies that rely on WPATH guidance and the Secretary of Health and Human Services is directed to publish a literature review of best practices for treatment of gender dysphoria in children within 90 days.

1/ 🧵🎉🍾🥳 A 2024 year end review of the great gender debate. This was the year the world reached peak trans. The public at large has had enough of the absurdity and excess of gender ideology and politicians are listening (or losing if they don't). 2/ The years started with an attempt by the World Health Organization to create a new guideline of transgender health with a hopelessly biased development group.

🧵The Cass Review and reviews in Sweden and Finland have recommended that puberty blockers only be used in a research setting. However, Cass was clear that any research studies would need ethical approval and the case for further research on children is not there. 1/ Before any more children are put at risk, the existing data on puberty blockers needs to be studied properly. A first step should be publishing the data from the Joanna Olson-Kennedy study which have been withheld for political reasons. 2/cnn.com/2024/10/25/hea…

1/ The US Supreme Court decision on gender affirming care for minors will probably have less impact on gender medicine in general than anticipated. The bans only affect about half the states and only apply up to are 18. There are two other factors that will be more important. 2/ The first is litigation, which is starting against some of the biggest names in medicine. There are also investigations by state governments and congressional investigations will follow.

1/ Here's what Trump has said about stopping medical transition of minors. Some of it makes sense but other parts are questionable and probably unconstitutional.
2/ "I will sign and executive order instructing every federal agency to cease all programs that promote the concept of sex and gender transition at any age." Easy to do, and will make it easier to work for reform at the state and local level. Note that it includes adults.

1/ Some thoughts from Canada on how the US election will impact the gender debate. Rachel Levine will be fired and most of Biden's executive orders on the application of Title IX to sports and trans health care will be repealed. 2/ The Supreme Court will hear the Skremetti case on state bans on youth gender medicine before Trump takes office. If the case goes as expected, the result will be to leave the issue of youth gender medicine to the states.

1/ The authors of the Canadian Paediatric Society position statement on gender affirming care have now published a response to the recent letter to the editor calling for a review of the position statement in light of the Cass Review.
academic.oup.com/pch/advance-ar… 2/ The response repeats falsehoods such as the claim that the systematic reviews commissioned by the Cass Review excluded studies which were not randomized control trials when in fact the systematic reviews considered and evaluated all types of studies.

1/ The proposals by @ABDanielleSmith to protect gender-questioning youth in schools and healthcare are generally consistent with best international practice and evidence but there are still a few problem areas. .

@ABDanielleSmith 2/ Banning gender reassignment surgery on minors should be a non-issue. Activists claim it never happens but it does. Someone too young to get a tattoo shouldn't be able to get an elective double mastectomy.

1/ The Trevor Project study which claims that "anti-transgender" laws caused increases in suicide attempts among trans and non-binary youth is a flawed study that is being presented in a misleading and irresponsible way. 2/ The 72% increase in suicide attempts highlighted in the press release misrepresents data in the study which refers to an increase of 72% above the sample mean. Also, the methodology used cannot prove causation.

1/ The Department for Education in England no longer recognizes the concept of a trans child. The latest version of it statutory guidance on keeping children safe in schools has replaced LGBT with LGB and
gender questioning children.
assets.publishing.service.gov.uk/media/66cef97c…


2/ Compare with the 2023 statutory guidance which simply referred to "children who are LGBT" as a group and talks about the need for staff to provide a "safe space."
