Trends in Referrals to a Pediatric Transgender Clinic.

OBJECTIVES: We characterized referral trends over time at a transgender clinic within an integrated health system in Northern California. We identified the transition-related requests of pediatric transgender and gender-nonconforming patients and evaluated differences in referrals by age group. METHODS: Medical records were analyzed for all patients <18 years of age in the Kaiser Permanente Northern California health system who were referred to a specialty transgender clinic between February 2015 and June 2018. Trends in treatment demand, demographic data, service requests, and surgical history were abstracted from medical charts and analyzed by using descriptive statistics. RESULTS: We identified 417 unique transgender and gender-nonconforming pediatric patients. The median age at time of referral was 15 years (range 3-17). Most (62%) identified on the masculine spectrum. Of the 203 patients with available ethnicity data, 68% were non-Hispanic. During the study period, the clinic received a total of 506 referrals with a significant increase over time (P < .001). Most referrals were for requests to start cross-sex hormones and/or blockers (34%), gender-affirming surgery (32%), and mental health (27%). Transition-related requests varied by age group: younger patients sought more mental health services, and older patients sought hormonal and surgical services. Eighty-nine patients underwent gender-affirming surgeries, mostly before age 18 and most frequently mastectomies (77%). CONCLUSIONS: The increase in referrals supports the need for expanded and accessible health care services for this population. The transition-related care of patients in this large sample varied by age group, underscoring the need for an individualized approach to gender-affirming care.

Ventromedial prefrontal cortex thinning in preschool-onset depression.

BACKGROUND: The ventromedial prefrontal cortex (VMPFC) is a key center of affect regulation and processing, fundamental aspects of emotional competence which are disrupted in mood disorders. Structural alterations of VMPFC have consistently been observed in adult major depression and are associated with depression severity, yet it is unknown whether young children with depression demonstrate similar abnormalities. We investigated cortical thickness differences in the VMPFC of children with a history of preschool-onset depression (PO-MDD). METHODS: Participants in a longitudinal study of PO-MDD underwent structural brain imaging between the ages of 7 and 12 years. Using local cortical distance metrics, cortical thickness of the VMPFC was compared in children with and without a history of PO-MDD. RESULTS: Children previously diagnosed with PO-MDD (n=34) had significantly thinner right VMPFC vs. children without a history of PO-MDD [(n=95); F(1,126)=5.97, (p=.016)]. This effect was specific to children with a history of PO-MDD vs. other psychiatric conditions and was independent of comorbid anxiety or externalizing disorders. Decreases in right VMPFC thickness were predicted by preschool depressive symptoms independent of depressive symptoms in school age. LIMITATIONS: Results are cross-sectional and cannot distinguish whether thinner right VMPFC represents a vulnerability marker of MDD, consequence of MDD, or marker of remitted MDD. Longitudinal imaging is needed to contextualize how this difference relates to normative VMPFC structural development. CONCLUSIONS: Onset of depression at preschool age was associated with decreased cortical thickness of right VMPFC. This finding implicates the VMPFC in depression from very early stages of brain development.
