Uncovering one of the driving forces of Alzheimer disease A Flinders University study has shown how a protein called tau, a critical factor in the development of Alzheimer disease, turns from normal to a disease state — and demonstrates how this discovery could deliver a therapeutic target. Published in Science Advances, the mouse study set out to answer whether a change at one specific site in tau would make it easier for another site to be modified. The team focused on the relationship between tau and protein kinases, which are enzymes that introduce changes in tau. The researchers conducted a large experiment that included up to 20 different changes in tau and 12 enzymes, focusing on the most abundant type of change seen in tau from the brains of patients with Alzheimer disease. While the study did discover that one change in tau does makes it easier for another change to be introduced, it was also able to identify “master sites” in tau, being specific locations that govern subsequent modifications at most of the other sites. “By modifying these master sites, we were able to drive modification at multiple other spots within tau, leading to a similar state seen in the brains of Alzheimer’s patients,” said the authors. The team will now investigate how its findings can be translated into a treatment. https://www.science.org/doi/10.1126/sciadv.abl8809 Hospital readmissions for asthma on the rise among children Hospital readmissions for asthma are increasing among children, according to research from the Murdoch Children’s Research Institute, . The study found about one in three children, mostly pre‐schoolers, are readmitted to hospital for asthma compared to one in five a decade ago. The study involved 767 children, aged 3 to 18years, who were admitted to three hospitals in Victoria between 2017 and 2018 with a diagnosis of asthma. It found 34.3% were readmitted to hospital for asthma, with those aged 3 to 5years accounting for 69.2%. Of the 767 participants, 20.6% were readmitted once and 13.7% had two or more readmissions in 12 months. “Our study highlighted gaps in the children’s asthma care,” lead author Dr Katherine Chen said. Over one‐third of children had not had a review of their inhaler technique and only about a quarter were prescribed a preventer or asked to continue using it. “Almost three‐quarters were discharged without a preventer medication and over 80% did not have a follow‐up clinic booked at the hospital, often reserved for children with difficult‐to‐control asthma. Most families therefore need to navigate their child’s asthma follow‐up with their GP.” https://www.tandfonline.com/doi/abs/10.1080/02770903.2022.2089996

Parental consent and the treatment of transgender youth: the impact of Re Imogen

To the Editor: We read with interest the article by Kelly and colleagues,1 In our opinion, the authors’ statement “Access to timely gender‐affirming care is associated with improved mental health outcomes and overall wellbeing” is not well supported by the two citations provided. The first citation is a systematic review by Rew and colleagues.2 A critique of this review was recently published.3 Rew et al, in response, clarified that they did not make any causal statements about puberty blockers and reported improved mental health outcomes, but believe their findings warrant more rigorous longitudinal studies.4 Kelly and colleagues’ second citation is a systematic review by Mahfouda et al.5 This review concluded there is only scarce and preliminary evidence that hormonal and surgical gender‐affirming treatments in adolescents are associated with mental health benefit and improved quality of life. The available evidence was described as having multiple methodological limitations and being at medium to high risk of bias. The authors called for further urgent research to clarify long term outcomes on psychological functioning and safety. Importantly, two recent systematic reviews by the United Kingdom’s National Institute for Health and Care Excellence found that the results of the studies investigating the benefits or adverse effects of puberty blockers and gender‐affirming hormones are of very low certainty and, as the studies themselves may not be reliable, any identified changes could be due to confounding, bias or chance.6,7 The recently published interim report of the UK’s Cass Review also noted that there are different views on the benefits versus harms of early social transition and more information about outcomes is required.8 In conclusion, the literature does not support there being a robust evidence base for the gender‐affirming social, medical and surgical interventions for children and adolescents. Rather, the literature highlights the scarce and low quality evidence and the urgent need for more high quality evidence. In any consideration of the processes of informed consent and/or court consent it would seem imperative that there is acknowledgement of the uncertain evidence base underpinning these interventions. Thus, it is of concern that Kelly and colleagues fail to do this.
