Retrospective Examination of Peripubertal Return for Patients of Western Australia's Gender Diversity Service.

Children far in advance of pubertal development may be deferred from further assessment for gender-affirming medical treatment until nearer puberty. It is vital that returning peripubertal patients are seen promptly to ensure time-sensitive assessment and provision of puberty suppression treatment where appropriate. This study investigates (1) how many referrals to the Child and Adolescent Health Service Gender Diversity Service at Perth Children's Hospital are deferred due to prepubertal status; and (2) how many deferred patients return peripubertally.

Reidentification With Birth-Registered Sex in a Western Australian Pediatric Gender Clinic Cohort.

Importance: Some young people who identify as transgender and seek gender-affirming medical care subsequently reidentify with their sex registered at birth. Evidence regarding the frequency and characteristics of this experience is lacking.

Objective: To determine the frequency of reidentification and explore associated characteristics in a pediatric gender clinic setting.

Potential immunological effects of gender-affirming hormone therapy in transgender people - an unexplored area of research.

There are well-described sex-based differences in how the immune system operates. In particular, cisgender (cis) females have a more easily activated immune system; associated with an increased prevalence of autoimmune diseases and adverse events following vaccinations. Conversely, cis males have a higher threshold for immune activation, and are more prone to certain infectious diseases, such as coronavirus disease (COVID-19).

The Perth Gender Picture (PGP): Young people's feedback about acceptability and usefulness of a new pictorial and narrative approach to gender identity assessment and exploration.

Background: A number of psychological assessment tools have been developed to describe various dimensions of gender. Some of these tools are restricted to a binary gender concept and are inflexible in reflecting how a young person's gender may change and develop over time. Most are text questionnaires which require a good level of literacy.

Lurasidone for Adolescents With Complex Mental Disorders: A Case Series.

Objectives: Lurasidone is a new second generation (atypical) antipsychotic agent with unique receptor affinity and side-effect profiles, but limited literature is available on its use in adolescent populations. Contrasting with research treatment trials which typically recruit patients by stringent selection criteria, this case series examined the effects and tolerability of using lurasidone in adolescents within real-life clinical settings in treating complex cases who had not responded to other therapy options.

Methods: We conducted a retrospective case-note audit of 6 adolescents aged 14 to 17 years old attending community child and adolescent mental health services (CAMHS) who were prescribed lurasidone.

Mental Health Correlates of Autism Spectrum Disorder in Gender Diverse Young People: Evidence from a Specialised Child and Adolescent Gender Clinic in Australia.

Research suggests an overrepresentation of autism spectrum diagnoses (ASD) or autistic traits in gender diverse samples, particularly in children and adolescents. Using data from the GENTLE (GENder identiTy Longitudinal Experience) Cohort at the Gender Diversity Service at the Perth Children's Hospital, the primary objective of the current retrospective chart review was to explore psychopathology and quality of life in gender diverse children with co-occurring ASD relative to gender diverse children and adolescents without ASD. The Social Responsiveness Scale (Second Edition) generates a (DSM-5) score indicating a likely clinical ASD diagnosis, which was used to partition participants into two groups (indicated ASD, = 19) (no ASD indicated, = 60).

Gender-affirming hormones and surgery in transgender children and adolescents.

The Endocrine Society Clinical Practice Guidelines on the treatment of gender incongruent people recommend the use of gender-affirming cross-sex hormone (CSH) interventions in transgender children and adolescents who request this treatment, who have undergone psychiatric assessment, and have maintained a persistent transgender identity. The intervention can help to affirm gender identity by inducing masculine or feminine physical characteristics that are congruent with an individual's gender expression, while aiming to improve mental health and quality-of-life outcomes. Some transgender individuals might also wish to access gender-affirming surgeries during adolescence; however, research to inform best clinical practice for surgeons and other medical professionals is scarce.

Using acute tryptophan depletion to investigate predictors of treatment response in adolescents with major depressive disorder: study protocol for a randomised controlled trial.

Background: Selective serotonin reuptake inhibitors (SSRIs) are amongst the most prescribed antidepressants for adolescents with depressive symptoms and major depressive disorder. However, SSRIs have significant shortcomings as a first-line treatment considering that not all patients respond to these antidepressants. Amongst paediatric populations, meta-analyses indicate that up to approximately 40% of patients do not respond, and for those who do show benefit, there is substantial heterogeneity in response onset.

Nitrous oxide (NO) and subsequent open-label SSRI treatment of adolescents with depression (NOTAD): study protocol for a randomised controlled trial.

Background: The first line of pharmacological treatment for severe depressive disorders in young people is selective serotonin reuptake inhibitors (SSRIs). However, beneficial clinical effects are rarely observed before several weeks into treatment. Nitrous oxide (NO) has a long-standing safety record for pain relief and has been used in adults and young people.

Functional connectivity of the vigilant-attention network in children and adolescents with attention-deficit/hyperactivity disorder.

The ability to maintain attention to simple tasks (i.e., vigilant attention, VA) is often impaired in attention-deficit/hyperactivity disorder (ADHD), but the underlying pathophysiological mechanisms at the brain network level are not clear yet.

Differences in serum zinc levels in acutely ill and remitted adolescents and young adults with bulimia nervosa in comparison with healthy controls - a cross-sectional pilot study.

Background: Research has implicated that changes in zinc (Zn) metabolism may be associated with the biological underpinnings of eating disorders, in particular anorexia nervosa. However, to date research on the role of Zn in patients with bulimia nervosa (BN) is scarce.

Objective: We aimed to explore serum Zn concentrations in young patients with BN, with a focus on the stage of the disorder, comparing acutely ill and recovered patients with BN with healthy controls.

Puberty suppression in transgender children and adolescents.

The World Professional Association for Transgender Health's standards of care recommend suspending puberty, preferably with the use of gonadotropin-releasing hormone agonists, in certain gender non-conforming minors (aged under 18 years) who have undergone a psychiatric assessment and have reached at least Tanner stage II of puberty. This approach seeks to lessen the discordance between assigned natal sex and gender identity by temporarily halting the development of secondary sexual characteristics, essentially widening the temporal window for gender clarification. Despite promising preliminary evidence on the clinical utility of this approach, there is a dearth of research to inform evidence-based practice.

Psychotropic drug prescribing in an Australian specialist child and adolescent eating disorder service: a retrospective study.

Background: To describe the rates, indications, and adverse effects of psychotropic drug prescription in a specialist tertiary hospital child and adolescent eating disorder service.

Methods: Retrospective case note study of all active eating disorder patients (N = 115) over the period of treatment from referral to time of study (M = 2 years), covering patient demographics, clinical characteristics, drug prescriptions, indications, and adverse effects.

Results: Psychotropic drugs were prescribed in 45% of cases, most commonly antidepressants (41%), followed by anxiolytics (29%) and antipsychotics (22%), with 8% initiated before referral to the specialist eating disorder program.

Costing day case anesthesia: obtaining accurate patient-based costs for adults and children.

Objectives: This study proposes the method requirements for a valid costing study in anesthesia to allow differences to be identified between treatments and uses these method requirements to design and conduct a robust costing study.

Methods: A prospective, patient-based costing study was carried out in adult and pediatric day surgery in the United Kingdom. The perspective was that of the National Health Service and the patient.
