Summary: This article traces the historical evolution of medical and psychiatric diagnoses related to transgender individuals. From ancient Greek and Roman writings to the development of medical classifications in the nineteenth century, the understanding of transgender people has evolved over time. The distinction between sexual orientation and gender diagnosis started to emerge in the early 1900s and continued to evolve until the modern era.

Summary: The study found that gender-affirming treatment has a greater impact on the sexual desire of transgender men than transgender women, and body image does not mediate the effects of GAHT or GAS on sexual desire. Gender-affirming therapy has a significant direct impact on body image, but body image itself does not directly affect sexual desire.

Summary: Gender dysphoria is the distress associated with having a gender identity different from one's birth-assigned sex. Hormonal treatment guidelines primarily cater to those transitioning from male to female or vice versa, leaving limited options for non-binary trans individuals seeking an androgynous appearance. There is potential for Selective Estrogen Receptor Modulators (SERMs) to be a gender-affirming treatment for non-binary individuals assigned male at birth (AMAB), but further research is needed on their effects and safety.

Summary: Concerns about future regret and treatment discontinuation have led to restricted access to gender-affirming medical treatment for transgender and gender-diverse minors in some jurisdictions. However, few studies have examined gender-affirming hormone continuation rates among TGD individuals. This study analyzed medical and pharmacy records to find that over 70% of TGD individuals who start gender-affirming hormones continue use beyond 4 years, with higher continuation rates in transfeminine individuals and those who started hormones as minors.

Summary: Empirical evidence on the psychosocial health outcomes of adolescents with GD after puberty suppression and gender-affirming medical interventions is limited. The study found that adolescents receiving gender-affirming interventions showed some improvement in psychosocial health outcomes, but there were still significant differences from the norm. This highlights the need for further longitudinal research on treatment decisions for transgender adolescents.

Summary: Exogenous testosterone therapy can lead to erythrocytosis, but the contribution of erythrocytosis to thrombosis in the context of gender-affirming hormonal therapy is unclear. A retrospective study on transgender and non-binary adults receiving testosterone showed that some patients developed elevated levels of hemoglobin and hematocrit, but thromboembolic events and hospitalizations related to erythrocytosis were uncommon.

Summary: This study aimed to evaluate perceived QoL, compare QoL scores between transgender women and men, and identify possible contributing factors related to GAHT. The results suggest that GAHT-related physical characteristics may impact QoL scores, and sociodemographic parameters may influence these associations. Healthcare providers should take these factors into consideration for interventions to improve QoL in transgender individuals.

Summary: With increasing demand for hormone treatment among transgender and gender nonbinary individuals, more research data is becoming available. A recent literature review found that gender-affirming hormone treatment can lead to increased life satisfaction and reduced psychological difficulties for those who feel it is necessary. The use of hormones can also change body composition and contours. Studies on bone health have shown reassuring results, but special attention is needed for adolescent and adult trans women in terms of hormone dosage and treatment compliance. The use of certain estrogens in trans women may increase the risk of myocardial infarction and stroke, highlighting the importance of lifestyle management in trans healthcare.

Summary: A survey conducted in Europe revealed a high degree of variability and discrepancy in the use of prenatal dexamethasone (Pdex) treatment for congenital adrenal hyperplasia (CAH). Only 36% of the surveyed medical centres provide Pdex treatment, and the starting point and dosage of the treatment vary among different centres. Limited availability of long-term follow-up registries was also observed. This highlights the importance of a European cooperation initiative to establish evidence-based guidelines for prenatal diagnostics, treatment, and follow-up of pregnancies at risk for CAH.

Summary: This study analyzed the use of salt supplementation, medication dosage, and growth indicators in children with CAH aged 0-3 years. The results showed that in children receiving additional salt supplementation, medication dosages were lower during the first months of life but there were no differences in weight, height, and blood pressure compared to those not receiving salt supplementation. All children showed an increase in BMI-SDS and a high proportion of blood pressure readings exceeding the normal range.

Summary: While there is variation in the definition and management of AI-related adverse events in children among centres, there is a good level of consensus on specific aspects that can lead to greater benchmarking of care. Over 90% of centres in high-income countries provided steroid management plans, one-to-one patient education, and contact details of health care staff. Additionally, the majority of centres recommended glucocorticoid stress dosing in the event of fever, and vomiting was the most common indication for intramuscular hydrocortisone injection.

Summary: The most common form of congenital adrenal hyperplasia is 21-hydroxylase deficiency (21OHD), occurring in 1:16 000 newborns worldwide. Lifelong treatment aims to replace deficiencies and suppress androgen production, but balancing between androgen excess and chronic high glucocorticoid exposure is challenging. Clinical assessment and biochemical parameters guide therapy, and understanding adrenal biomarker values is important. The pathophysiologic and pharmacologic principles are utilized to manage complications and consequences of 21OHD.

Summary: To evaluate the prevalence and clinical effects of elevated insulin-like growth factor 1 (IGF-1) concentrations in children with low grade glioma (LGG), a retrospective study collected tumor, treatment, endocrine, and auxological data from 358 children. The study found that 18.4% of children with available IGF-1 measurements had elevated IGF-1 concentrations, but no association was found between elevated IGF-1 concentrations and tumor behavior or height SDS at last follow-up. Elevated IGF-1 concentrations were associated with worsening hypothalamic dysfunction over time.

Summary: Research on uncertainty in medical practice lacks consensus and integration due to its scattered nature across disciplines. This hinders understanding of when and how uncertainty occurs, its impact on stakeholders and medical decision-making. The paper argues for a more integrated approach to uncertainty, using adolescent transgender care as an example.

Summary: Testicular adrenal rest tumors (TARTs) may arise from chronic stimulation of adrenocorticotropic hormone (ACTH)-sensitive cells in the testes. However, this study found that the human fetal testis (HFT) is unresponsive to ACTH, suggesting that TARTs do not arise from fetal testicular cells chronically exposed to ACTH in utero.
