The Structured Oral Examination: A Method to Improve Formative Assessment of Fellows in Pediatric Endocrinology.

OBJECTIVE: A structured oral exam (SOE) can be utilized as a formative assessment to provide high-quality formative feedback to trainees, but has not been adequately studied in graduate medical education. We obtained fellow and faculty perspectives on: 1) educational effectiveness, 2) feasibility/acceptability, and 3) time/cost of a SOE for formative feedback. METHODS: Four pediatric endocrinology cases were developed and peer-reviewed to generate a SOE. The exam was administered by faculty to pediatric endocrinology fellows individually, with feedback after each case. Fellow/faculty perspectives of the SOE were obtained through a questionnaire. Qualitative thematic analysis was utilized to analyze written comments generated by faculty and fellows. RESULTS: Seven of 10 pediatric endocrinology fellowship programs and all 18 fellows within those programs agreed to participate. Thematic analysis of fellow and faculty comments resulted in 5 perceived advantages of the SOE: 1) improved identification of clinically relevant knowledge deficits, 2) improved assessment of clinical reasoning, 3) immediate feedback/teaching, 4) assurance of adequate teaching/assessment of uncommon cases, and 5) more clinically relevant assessment. Mean time to administer one case was 15.8 minutes (2.0) and was mentioned as a potential barrier to implementation. Almost all fellows (17/18, 94%) and faculty (6/7, 86%) would recommend or would most likely recommend implementation of the SOE into their curriculum. CONCLUSIONS: The SOE utilized for formative feedback was perceived by fellows and faculty to have several educational advantages over current assessments and high acceptability. Objective educational advantages should be assessed on future studies of the SOE.

Is There a Link Between Hormone Use and Diabetes Incidence in Transgender People? Data From the STRONG Cohort.

BACKGROUND: Risk of type 2 diabetes mellitus (T2DM) in transgender and gender diverse (TGD) persons, especially those receiving gender-affirming hormone therapy (GAHT) is an area of clinical and research importance. METHODS: We used data from an electronic health record-based cohort study of persons 18 years and older enrolled in 3 integrated health care systems. The cohort included 2869 transfeminine members matched to 28 300 cisgender women and 28 258 cisgender men on age, race/ethnicity, calendar year, and site, and 2133 transmasculine members similarly matched to 20 997 cisgender women and 20 964 cisgender men. Cohort ascertainment spanned 9 years from 2006 through 2014 and follow-up extended through 2016. Data on T2DM incidence and prevalence were analyzed using Cox proportional hazards and logistic regression models, respectively. All analyses controlled for body mass index. RESULTS: Both prevalent and incident T2DM was more common in the transfeminine cohort relative to cisgender female referents with odds ratio and hazard ratio (95% CI) estimates of 1.3 (1.1-1.5) and 1.4 (1.1-1.8), respectively. No significant differences in prevalence or incidence of T2DM were observed across the remaining comparison groups, both overall and in TGD persons with evidence of GAHT receipt. CONCLUSION: Although transfeminine people may be at higher risk for T2DM compared with cisgender females, the corresponding difference relative to cisgender males is not discernable. Moreover, there is little evidence that T2DM occurrence in either transfeminine or transmasculine persons is attributable to GAHT use.

Progression of Gender Dysphoria in Children and Adolescents: A Longitudinal Study.

BACKGROUND AND OBJECTIVES: The progression of gender-expansive behavior to gender dysphoria and to gender-affirming hormonal treatment (GAHT) in children and adolescents is poorly understood. METHODS: A cohort of 958 gender-diverse (GD) children and adolescents who did not have a gender dysphoria-related diagnosis (GDRD) or GAHT at index were identified. Rates of first GDRD and first GAHT prescription were compared across demographic groups. RESULTS: Overall, 29% of participants received a GDRD and 25% were prescribed GAHT during the average follow-up of 3.5 years (maximum 9 years). Compared with youth assigned male sex at birth, those assigned female sex at birth were more likely to receive a diagnosis and initiate GAHT with hazard ratio (95% confidence interval) estimates of 1.3 (1.0-1.7), and 2.5 (1.8-3.3), respectively. A progression to diagnosis was more common among those aged ≥15 years at initial presentation compared with those aged 10 to 14 years and those aged 3 to 9 years (37% vs 28% vs 16%, respectively). By using the youngest group as a reference, the adjusted hazard ratios (95% confidence interval) for a GDRD were 2.0 (1.3-3.0) for age 10 to 14 years and 2.7 (1.8-3.9) for age ≥15 years. Racial and ethnic minorities were less likely to receive a diagnosis or be prescribed GAHT. CONCLUSIONS: This study characterized the progression of GD behavior in children and adolescents. Less than one-third of GD youth receive an eventual GDRD, and approximately one-quarter receive GAHT. Female sex at birth, older age of initial GD presentation to medical care, and non-Hispanic white race and ethnicity increased the likelihood of receiving diagnosis and treatment.

Changes in Size and Demographic Composition of Transgender and Gender Non-Binary Population Receiving Care at Integrated Health Systems.

OBJECTIVE: To examine temporal changes in the number and demographic composition of transgender/gender non-binary (TGNB) population using data from integrated health care systems. METHODS: Electronic health records from Kaiser Permanente health plans in Georgia and Northern and Southern California were used to identify TGNB individuals, who sought care from January 2006 to December 2014, and the data were analyzed by year, site, age, and sex assigned at birth. RESULTS: In 2006, the number of TGNB people (and corresponding 95% CI) per 100 000 population were 3.5 (1.9, 6.3) in Georgia, 5.5 (4.8, 6.4) in Southern California, and 17 (16, 19) in Northern California. In 2014, these frequencies increased to 38 (32, 45), 44 (42, 46), and 75 (72, 78) per 100 000 population, respectively. When analyzed by age, the most rapid increase was observed among persons 18 to 25 years old, and this increase accelerated after 2010. The ratio of transmasculine to transfeminine persons also changed from 1:1.7 in 2006 to 1:1 in 2014 overall and from 1:1 in 2006 to 1.8:1 in 2014 among persons <18 years of age. CONCLUSION: This analysis confirms previous observations that the proportion of TGNB people is growing, especially among young adults. The composition of the TGNB population is also changing from predominantly transfeminine to roughly 1:1 overall and to predominantly transmasculine in children and adolescents.

The effect of early puberty suppression on treatment options and outcomes in transgender patients.

In the past 10-15 years, paediatric transgender care has emerged at the forefront of several general practice and subspecialty guidelines and is the topic of continuing medical education for various medical disciplines. Providers in specialties ranging from family medicine, paediatrics and adolescent medicine to endocrinology, gynaecology and urology are caring for transgender patients in increasing numbers. Current and evolving national and international best practice guidelines recommend offering a halt of endogenous puberty for patients with early gender dysphoria, in whom impending puberty is unacceptable for their psychosocial health and wellness. Pubertal blockade has implications for fertility preservation, transgender surgical care and psychosocial health, all of which must be considered and discussed with the patient and their family and/or legal guardian before initiation.

Transgender medicine - puberty suppression.

Puberty suppression is the reversible first step of endocrine medical treatment in transgender youth, and allows for two very important aspects of transgender management. Firstly, it buys the patient, family and their medical team time to fully evaluate the presence and persistence of gender dysphoria. Secondly, it successfully prevents the development of cis-gender unwanted secondary sexual characteristics. The latter, when present, almost certainly increase the burden of psychological co-morbidity for any transgender person. This management is modelled from treatment of gonadotropin-dependent precious puberty, with use of GnRH agonists at its core. With the increasing number of transgender youth treated, and the changing demographics of patients seeking medical care, providers are faced with the decision to start puberty blockade at younger ages than previous decades. This article will review the rationale behind puberty blockade for transgender children, the providers' options for achieving this goal, the emerging literature for potential adverse effects on such an approach, as well as identify directions of potential future research.

HIV-1 proteins accelerate HPA axis habituation in female rats.

Congenital infection by the Human Immunodeficiency Virus (HIV) has been shown to lead to multiple co-morbidities, and people living with HIV have a higher incidence of affective and anxiety disorders. A marked increase in mood disorders is evident during the sensitive phase of adolescence and this is further pronounced in females. Depression has been linked to dysfunction of the intracellular response system to corticosteroids at the level of the hippocampus (HC) and prefrontal cortex (PFC) with a notable role of the glucocorticoid receptor (GR) and its co-chaperones (FKBP5 and FKBP4). The current study examined the extent to which HIV protein expression in adolescent female rats altered the stress response at both the level of corticosterone output and molecular regulation of the glucocorticoid receptor in the brain. WT and HIV-1 genotype female rats were randomly allocated in control, acute stress and repeat stress groups. Corticosterone plasma levels and expression of GR, FKBP4, and FKBP5 in the HC and PFC were measured. The presence of HIV-1 proteins facilitates habituation of the corticosterone response to repeated stressors, such that HIV-1 TG rats habituated to repeated restraint and WT rats did not. This was reflected by interactions between stress exposure and HIV-1 protein expression at the level of GR co-chaperones. Although expression of the GR was similarly reduced after acute and repeat stress in both genotypes, expression of FKBP5 and FKBP4 was altered in a brain-region specific manner depending on the duration of the stress exposure and the presence or absence of HIV-1 proteins. Collectively, the data presented demonstrate that HIV-1 proteins accelerate habituation to repeated stressors and modify the influence of acute and repeat stressors on GR co-chaperones in a brain region-specific manner.

Development of the HPA axis: where and when do sex differences manifest?

Sex differences in the response to stress contribute to sex differences in somatic, neurological, and psychiatric diseases. Despite a growing literature on the mechanisms that mediate sex differences in the stress response, the ontogeny of these differences has not been comprehensively reviewed. This review focuses on the development of the hypothalamic-pituitary-adrenal (HPA) axis, a key component of the body's response to stress, and examines the critical points of divergence during development between males and females. Insight gained from animal models and clinical studies are presented to fully illustrate the current state of knowledge regarding sex differences in response to stress over development. An appreciation for the developmental timelines of the components of the HPA axis will provide a foundation for future areas of study by highlighting both what is known and calling attention to areas in which sex differences in the development of the HPA axis have been understudied.
