State of Hormones Impact Nociceptive Expression
The Investigators have recently published on differences in pain sensitivity measures between cis and trans individuals in the local area. The investigators observed the anticipated differences in pain sensitivity between CM and CW (CW \> CM), but found that the TW were phenotypically similar to CW in all measures. However, the investigators did not assess hormone level, nor did the investigators recruit TM participants. Here, with the assistance of two local community group stakeholders the investigators will recruit the following groups: CM, CW, TM+T (currently taking exogenous testosterone), TW+E (exogenous estradiol), TM, and TW (n=20/group). The investigators will use quantitative sensory testing to assess sensitivity to cold, pressure, and heat via standardized protocols. Blood samples will be taken for assessment of stress and reproductive hormone levels, immune cell populations and stimulated cytokine release. Finally, questionnaires will measure pain state, quality of life (QOL), voice QOL, body image, appearance, self-reported health, masculinity/femininity, community connectedness, gender role, sleep, depression, social support, adverse childhood experiences and stigma.

TransHealthGUIDE: Transforming Health for Gender-Diverse Young Adults
This is a randomized controlled trial to test the effectiveness of an interactive educational app-based digital intervention that provides knowledge and support to transgender and gender-diverse (TGD) young adults ages 18-29 years and their caregivers. The goal of the study is to examine the effects of exposure to the app on TGD young adult mental health outcomes. Participants will be randomized to an Immediate Arm (access to a digital platform, plus usual care) or a Deferred Arm (usual care; access to the digital platform at 6 mo). Usual care consists of access to published resources and community support organizations, if available. The list of resources will include contact information for a suicide prevention hotline. For each Arm, the intervention period will last 6 months, followed by 6 months of observation, during which access to the intervention is maintained. Assessments will be performed at baseline, 3, 6, and 12 months to document changes in mental health outcomes, and the two groups will be compared. The investigators plan to enroll 500 TGD young adults and their caregivers, with at least 50% (250 participants) to identify as Black, Indigenous, People of Color (BIPOC) and 50% (125 TGD young adults, 125 caregivers) to be young adult-caregiver dyads. Ongoing process reassessments will be performed to maximize effectiveness of the intervention, including focus groups and in-depth interviews with TGD young adults, caregivers, and providers, as well as analysis of data collected through the digital platform and participant surveys. Investigators will account for sociodemographic characteristics such as race and ethnicity, age, gender identity, education status, existing mental health conditions, and history of suicidal ideation or attempt. Data will be analyzed across racial minority groups to ensure that the intervention is effective for all racial minorities; if there are discrepancies in effectiveness, additional mixed methods evaluation will be performed to identify and address potential causes.

Efficacy of a Chronic Pain Treatment Prior to Gender-affirming Surgery
The primary objective of this study is to examine a single-session, 2-hour group intervention provided to a population of transgender or gender-diverse patients with chronic pain prior to gender-affirming surgery, to determine if participants who receive the intervention have less pain-related distress compared to participants randomly assigned to the control group.

Effect of Hormones on Frequency of Headache and Brain Structure and Function in Puberty
With a rising population of transgender adults and youth, there is a need for more research to meet the needs of this community. Transfemale (MTF) youth (male sex, female gender identity) who begin clinical Gender Affirming Hormone Therapy (GAHT) with estrogen may be at a higher risk for headache since estrogen has been linked to headache in cisgender females (female sex, female gender identity). This research hopes to learn more about headache in MTF youth.

The Copenhagen Gender Identity Cohort
The goal of this observational study is to systematically collect data on adults seeking medical and surgical treatments for gender incongruence. This prospective, longitudinal cohort aims to generate insights into the safety, effectiveness, and overall satisfaction with current treatments. Additionally, the study seeks to identify areas for improvement and support healthcare professionals in making informed decisions. Most importantly, it aims to enhance the quality of life for transgender and gender-diverse individuals by ensuring that the care they receive aligns with their needs and goals. Participants will include patients seeking treatment at the Copenhagen Center for Gender Identity, Denmark. Data collection will be both clinician- and patient-reported. Participants will be asked to complete online surveys at baseline, after the assessment process, and annually if they initiate hormone therapy. The study will systematically gather information on gender identity and transition experiences, sociodemographics, self-medication, health status, self-reported quality of life, and treatment preferences. Additionally, detailed records of treatment courses and specific interventions will be collected from all involved healthcare providers across specialties. The study will evaluate the effects of different treatment options, both in the short and long term. It will explore how quality of life is associated with gender identity, transition, sociodemographics, lifestyle, and health, as well as assess the medical impact of various treatments, including counseling, hormone therapy, and surgery. Furthermore, the study will investigate the prevalence of side effects and complications related to treatment, as well as factors influencing treatment discontinuation, including cases of detransition. Finally, the project will focus on quality indicators such as waiting times and patient satisfaction, contributing to the ongoing development of high-quality, patient-centered care for transgender and gender-diverse individuals.

Puberty, Testosterone, and Brain Development
Transmasculine youth (female sex assigned at birth, male gender identity) who begin clinical gender affirming hormone therapy (GAHT) with testosterone (T) may experience changes in headache. Researchers think this because studies published on effects of giving testosterone to cisgender females (female sex, female gender identity) and transmasculine adults seem to show an effect on pain. This research will help us learn more about changes in headache and in brain structure and function in transmasculine youth during the first two years of T. Youth who will be starting T within 6 months, either on puberty blocker or not, as part of their regular medical care can participate and will be asked to attend 4 visits: * before starting T * after 6 months on T * after 1 year on T * after 2 years on T At the visits, they will be asked to: * answer questions and surveys about their health * have a brain MRI done * give a small sample of blood and at their first visit, complete a physical exam. Some participants can also do a brief test of pain sensitivity. All participants will be asked to complete a headache diary for the first 6 months, for 1 month after the 1 year visit, and for 1 month after the 2 year visit.

Increasing Effective Mental Health Care for LGBT Clients
The overall aims of the 5-year University of Maryland Prevention Research Center (UMD-PRC) Core Research Project are to identify, refine, implement, evaluate, translate, disseminate, and communicate approaches and tools that can be used to improve the competency of mental health care for LGBT persons which is a social determinant of LGBT health disparities. The UMD-PRC research team, in collaboration with the community advisory board (CAB), have identified 5 evidence based resources (Tools) to improve health care competency with sexual and gender minority populations (lesbian/gay, bisexual, and transgender \[LGBT\] people). The UMD-PRC will use the Sexual and Gender Diversity Learning Community (SGDLC) program (Strategy) and these tools along with technical assistance (TA) to improve LGBT mental health care. The following hypothesis will be tested. The study intervention group will show an increase in a) organization-level LGBT-friendly policies and environment as observed by the researchers and b) LGBT competent clinician practice assessed through clinician self-reported preparedness, awareness, and knowledge as well as referral for co-occurring client health needs; client-reported satisfaction with therapy and health literacy; and research team assessment of clinician performance providing consultation to a standardized LGBT patient actor.

Early Mental Response - The EMRE Study
Primary question: Does transgender men's experience of gender incongruence improve within 6 weeks of hormonal treatment compared to placebo? Long before any bodily changes occur. Secondary question: Does transgender men´s experience of self-esteem, quality of life, sexual desire, aggression, depression/anxiety, impulsiveness, and emotional reactivity improve during 6 weeks of cross-sex hormone therapy compared to placebo? Gender dysphoria is a condition characterized by a perceived incongruence between the body and identity. For several decades this condition has been treated with cross-sex hormone therapy and surgery, among others, in order to change the body to be more congruent with the perceived gender identity. Patient satisfaction with this treatment is very high where an overwhelming majority of patients live the rest of their lives according to their perceived gender. A clinical observation, however, is that most patients experience that the congruence between the perceived gender and the assigned one improves very quickly on hormonal treatment. Long before any changes to the body have taken place. This may be partly due to relief from having finally started treatment (i.e. a psychological/social explanation) but an alternative (and much more likely) explanation is that the hormonal treatment directly affects the brain. Since the cause of gender dysphoria is unknown today, this study is therefore a step in trying to clarify the mechanism. In addition, it is of value to be able to demonstrate the benefits of hormonal treatment in these patients. Finally, there is a basic research motive for this study. The effect of sex hormones on the brain is very well known from a clinical perspective but all the more unknown from a research perspective. This study will contribute knowledge in this area.
