[Beyond NICE: Updated Systematic Review on the Current Evidence of Using Puberty Blocking Pharmacological Agents and Cross-Sex-Hormones in Minors with Gender Dysphoria]

Beyond NICE: Updated Systematic Review on the Current Evidence of Using Puberty Blocking Pharmacological Agents and Cross-Sex-Hormones in Minors with Gender Dysphoria Abstract: Objective: The suppression of physiological puberty using puberty-blocking pharmacological agents (PB) and prescribing cross-sex hormones (CSH) to minors with gender dysphoria (GD) is a current matter of discussion, and in some cases, PB and CSH are used in clinical practice for this particular population. Two systematic reviews (one on PB, one on CSH treatment) by the British National Institute for Clinical Excellence (NICE) from 2020 indicated no clear clinical benefit of such treatments regarding critical outcome variables. In particular, these two systematic NICE reviews on the use of PB and CSH in minors with GD detected no clear improvements of GD symptoms. Moreover, the overall scientific quality of the available evidence, as discussed within the above-mentioned two NICE reviews, was classified as "very low certainty" regarding modified GRADE criteria. Method: The present systematic review presents an updated literature search on this particular topic (use of PB and CSH in minors with GD) following NICE principles and PICO criteria for all relevant new original research studies published since the release of the two above-mentioned NICE reviews (updated literature search period was July 2020-August 2023). Results: The newly conducted literature search revealed no newly published original studies targeting NICE-defined critical and important outcomes and the related use of PB in minors with GD following PICO criteria. For CSH treatment, we found two new studies that met PICO criteria, but these particular two studies had low participant numbers, yielded no significant additional clear evidence for specific and clearly beneficial effects of CSH in minors with GD, and could be classified as "low certainty" tfollowing modified GRADE criteria. Conclusions: The currently available studies on the use of PB and CSH in minors with GD have significant conceptual and methodological flaws. The available evidence on the use of PB and CSH in minors with GD is very limited and based on only a few studies with small numbers, and these studies have problematic methodology and quality. There also is a lack of adequate and meaningful long-term studies. Current evidence doesn't suggest that GD symptoms and mental health significantly improve when PB or CSH are used in minors with GD. Psychotherapeutic interventions to address and reduce the experienced burden can become relevant in children and adolescents with GD. If the decision to use PB and/or CSH is made on an individual case-by-case basis and after a complete and thorough mental health assessment, potential treatment of possibly co-occurring mental health problems as well as after a thoroughly conducted and carefully executed individual risk-benefit evaluation, doing so as part of clinical studies or research projects, as currently done in England, can be of value in terms of generation of new research data.

[Practical Guideline on Dealing with Transgender Patients in Child and Adolescent Psychiatric Inpatient Settings]

Practical Guideline on Dealing with Transgender Patients in Child and Adolescent Psychiatric Inpatient Settings Abstract: The guideline provided by the Federal Association of Leading Medical Directors for Child and Adolescent Psychiatry offers a framework for dealing with transgender patients in child and adolescent psychiatric clinics. It addresses the clinical challenges arising from the significant increase in transgender patients and the paradigm shift in the medical field. The guideline includes recommendations for dealing with transgender patients in various settings. Key treatment principles comprise adopting a destigmatizing approach, using preferred names and pronouns, accommodating individual room assignments, and considering relevant comorbidities. Only experienced medical doctors and psychotherapists should carry out diagnosis and treatment. The goals for supporting adolescents with gender dysphoria include promoting self-acceptance, addressing negative emotions, facilitating social integration, and fostering identity development.

Adolescent Development of Biological Rhythms in Female Rats: Estradiol Dependence and Effects of Combined Contraceptives

Adolescence is a period of continuous development, including the maturation of endogenous rhythms across systems and timescales. Although, these dynamic changes are well-recognized, their continuous structure and hormonal dependence have not been systematically characterized. Given the well-established link between core body temperature (CBT) and reproductive hormones in adults, we hypothesized that high-resolution CBT can be applied to passively monitor pubertal development and disruption with high fidelity. To examine this possibility, we used signal processing to investigate the trajectory of CBT rhythms at the within-day (ultradian), daily (circadian), and ovulatory timescales, their dependence on estradiol (E2), and the effects of hormonal contraceptives. Puberty onset was marked by a rise in fecal estradiol (fE2), followed by an elevation in CBT and circadian power. This time period marked the commencement of 4-day rhythmicity in fE2, CBT, and ultradian power marking the onset of the estrous cycle. The rise in circadian amplitude was accelerated by E2 treatment, indicating a role for this hormone in rhythmic development. Contraceptive administration in later adolescence reduced CBT and circadian power and resulted in disruption to 4-day cycles that persisted after discontinuation. Our data reveal with precise temporal resolution how biological rhythms change across adolescence and demonstrate a role for E2 in the emergence and preservation of multiscale rhythmicity. These findings also demonstrate how hormones delivered exogenously in a non-rhythmic pattern can disrupt rhythmic development. These data lay the groundwork for a future in which temperature metrics provide an inexpensive, convenient method for monitoring pubertal maturation and support the development of hormone therapies that better mimic and support human chronobiology.

[Changes of sex ratio and prevalence in transgender teenagers over the past 15 years]

Changes of sex ratio and prevalence in transgender teenagers over the past 15 years Abstract. Evaluation of authors' 1434 expert opinions from 2005-2019 on transgender applicants (420 younger than 20 years old) for legal change of name and gender according to German "Law on Transsexuality" showed (1) in teenage applicants substantial changes of sex ratio from 2:1 to 10:1 in favour of transmales; (2) while prevalence of teenage transfemales during this period remained unchanged, prevalence of transmales rose significantly. According to our data, transgender teenagers are nowadays primarily natal females. Clinical and sociocultural aspects of these changes are discussed.

[Therapeutic Models for Children and Adolescents with Gender Dysphoria: Overview with Focus on Austrian Treatment Reality]

Therapeutic Models for Children and Adolescents with Gender Dysphoria: Overview with Focus on Austrian Treatment Reality Young people whose experienced gender differs from their aligned sex are increasingly visible in public life as well as in the medical care system. For those children and adolescents, who can experience a high degree of suffering because of the discrepancy between aligned sex and desired gender, treatment guidelines have been developed. In this short narrative review, classification options, epidemiological data, health-care data and treatment guidelines are presented with an emphasis on the Austrian health care system.
