Pain mechanisms in the transgender individual: a review

Specific Aim

Provide an overview of the literature addressing major areas pertinent to pain in transgender persons and to identify areas of primary relevance for future research.

Methods

A team of scholars that have previously published on different areas of related research met periodically though zoom conferencing between April 2021 and February 2023 to discuss relevant literature with the goal of providing an overview on the incidence, phenotype, and mechanisms of pain in transgender patients. Review sections were written after gathering information from systematic literature searches of published or publicly available electronic literature to be compiled for publication as part of a topical series on gender and pain in the Frontiers in Pain Research.

Results

While transgender individuals represent a significant and increasingly visible component of the population, many researchers and clinicians are not well informed about the diversity in gender identity, physiology, hormonal status, and gender-affirming medical procedures utilized by transgender and other gender diverse patients. Transgender and cisgender people present with many of the same medical concerns, but research and treatment of these medical needs must reflect an appreciation of how differences in sex, gender, gender-affirming medical procedures, and minoritized status impact pain.

Conclusions

While significant advances have occurred in our appreciation of pain, the review indicates the need to support more targeted research on treatment and prevention of pain in transgender individuals. This is particularly relevant both for gender-affirming medical interventions and related medical care. Of particular importance is the need for large long-term follow-up studies to ascertain best practices for such procedures. A multi-disciplinary approach with personalized interventions is of particular importance to move forward.

Two Gender Medicine: Provider-Side Barriers to Caring for Transgender and Gender Diverse Patients

Experienced and anticipated discrimination during health care visits result in lower health care utilization rates, which contribute to persistent health disparities between transgender and gender diverse (TGD) individuals and the general population. Most strategies for improving health care delivery to TGD patients place the responsibility on providers, overlooking the role of medical systems and institutions in creating the environments where negative health care experiences occur. Relying on the inhabited institutionalism framework, this study explores system- and institutional-level barriers to the provision of quality care to TGD patients identified by health care providers and administrators, including relevant contextual details of, and interactions between, these barriers. Based on interview data from health care providers and administrators from a variety of practices across Texas, we identified two overarching themes and six subthemes. We demonstrate how our interviewees' responses reveal an institutional logic of "two-gender medicine," which creates barriers to health care provision in both formal medical education and training and throughout the managed care model of practice. We also illustrate how health care workers find ways to resist this logic in the course of their practice. Addressing these barriers to delivering competent and compassionate care to TGD patients that providers encounter could make long overdue strides toward addressing health disparities.

A prospective comparison study of subcutaneous and intramuscular testosterone injections in transgender male adolescents

OBJECTIVES

This prospective study compares testosterone injection type and effects on biochemical changes, clinical effects, and quality of life amongst transgender and gender diverse (TGD) adolescents assigned female at birth (AFAB) over the first 6 months of subcutaneous (SQ) vs. intramuscular (IM) testosterone injections as part of their gender affirming care.

METHODS

Subjects were testosterone-naïve transgender adolescents, AFAB, ages 14-18 years old. Subjects were either randomized to injection type or selected a preferred injection type. At enrollment, subjects completed baseline labs and PedsQL™ quality of life questionnaire. At 3 month and 6 month follow up, subjects completed peak and trough testosterone levels, PedsQL™, masculinizing effects, and medication experience questionnaires.

RESULTS

Twenty-six subjects participated with a median age 15.5 years. By 6-month follow up, trough testosterone levels were comparable between the two groups. Peak testosterone levels were higher in the IM group at 3-month follow up. Mild adverse effects were rare (12 %, all in SQ subjects) and limited to skin reaction only. Self-reported masculinization effects and quality of life were not statistically different between injection groups. A total of 92 % of participants was self-injecting by 3-month follow up.

CONCLUSIONS

In this prospective study, clinical and biochemical effects are similar between SQ and IM testosterone injections for transgender adolescents. Subjects expressed preference for both injection types. Both SQ and IM injection modalities are safe and effective for TGD youth initiating testosterone and both options should be offered to patients.

Increasing safe clinical spaces and the efforts of clinical research for uninsured and underinsured LGBTQIA2+ patients: A case study of the Rainbow Clinic - a student-run free LGBTQIA2+ clinic

LGBTQIA2+ patients often experience discrimination and hostility in healthcare spaces. Negative perceptions of healthcare can contribute to poor health outcomes in LGBTQIA2+ patients. This population is rarely included in clinical trials through a lack of inclusion in study protocols, informed consent, and trials not addressing their needs and demographics. Many clinical institutions have created LGBTQIA2+-specific clinics; however, few have successfully developed a free clinic dedicated to this population. A Rainbow Clinic was formed at an established student-run free clinic, utilizing the existing infrastructure. Dissemination of this clinic's creation can help others replicate similar initiatives.

Erythrocytosis in Gender-Affirming Care With Testosterone

PURPOSE

Gender-affirming hormone therapy (GAHT) is safe overall, with few adverse effects. One potential effect from using testosterone for GAHT is an increase in hemoglobin and/or hematocrit, known as secondary erythrocytosis. Current guidelines recommend monitoring hemoglobin or hematocrit routinely in the first year, some as frequently as every 3 months, which can create barriers to care. Our study explored the incidence of erythrocytosis in the first 20 months of testosterone therapy among people receiving gender-affirming care.

METHODS

This is a descriptive fixed cohort study of hematocrit and hemoglobin data from the charts of 282 people taking testosterone for GAHT.

RESULTS

During the first 20 months of testosterone therapy, the cumulative incidence of hematocrit >50.4% was 12.6%, hematocrit >52% was 1.0%, and hematocrit >54% was 0.6%. All people were taking injectable testosterone cypionate, with a median dose of 100 mg weekly.

CONCLUSION

Severe erythrocytosis (hematocrit >54%) is a rare outcome of gender-affirming testosterone therapy. Clinical recommendations should reconsider the need for routine frequent erythrocytosis screening within the first year of testosterone therapy for patients who prefer to minimize laboratory draws.

White paper: Gender affirming care in college health

College health services are uniquely situated to reduce barriers that have historically made it difficult for Transgender and Gender Diverse (TGD) people to access care. The Big 10 Gender Care Coalition recognizes the importance of providing gender-affirming care and presents recommendations for integrative, inclusive college health services.

Initial Clinical Needs Among Transgender and Non-binary Individuals in a Large, Urban Gender Health Program

BACKGROUND

Transgender and gender-diverse individuals are particularly vulnerable to healthcare discrimination and related health sequelae.

OBJECTIVE

To demonstrate diversity in demographics and explore variance in needs at the time of intake among patients seeking care at a large, urban gender health program.

DESIGN

We present summary statistics of patient demographics, medical histories, and gender-affirming care needs stratified by gender identity and sexual orientation.

PARTICIPANTS

We reviewed all intake interviews with individuals seeking care in our gender health program from 2017 to 2020.

MAIN MEASURES

Clients reported all the types of care in which they were interested at the time of intake as their "reason for call" (i.e., establish primary care, hormone management, surgical services, fertility services, behavioral health, or other health concerns).

KEY RESULTS

Of 836 patients analyzed, 350 identified as trans women, 263 as trans men, and 223 as non-binary. The most prevalent sexual identity was straight among trans women (34%) and trans men (38%), whereas most (69%) non-binary individuals identified as pansexual or queer; only 3% of non-binary individuals identified as straight. Over half of patients reported primary care, hormone management, or surgical services as the primary reason for contacting our program. Straight, transgender women were more likely to report surgical services as their primary reason for contacting our program, whereas gay transgender men were more likely to report primary care as their reason.

CONCLUSIONS

Individuals contacting our gender health program to establish care were diverse in sexual orientation and gender-affirming care needs. Care needs varied with both gender identity and sexual orientation, but primary care, hormone management, and surgical services were high priorities across groups. Providers of gender-affirming care should inquire about sexual orientation and detailed treatment priorities, as trans and gender-diverse populations are not uniform in their treatment needs or goals.

Transition Trajectories: Contexts, Difficulties and Consequences Reported by Young Transgender and Non-Binary Spaniards

The transition process can have a significant impact on young transgender and non-binary individuals (TNBI), especially regarding their mental health. As such, this study aimed to explore the encountered difficulties and expectations of 225 young adults, between 14 and 25 years old, who identify themselves as TNBI. Four different aspects were analyzed: difficulties related to the transition process; main current difficulties; if the current difficulties are due to the participants’ sexual orientation or gender identity; and if participants feel the need of changing something in their lives. Several obstacles either before, during or after the transition process were identified; and these obstacles have serious consequences in TBNI’s mental health. Questions regarding legislation, discrimination, transphobia, lack of social support, the pathologization of transgenderism, low self-esteem, anxiety symptomatology, among others, were pointed out by the participants. The narratives collected and analyzed in the present study appear as important inputs to the literature, which can be translated into the basis of further investigations and the improvement of professional practices in the health field.

"I knew that I wasn't cis, I knew that, but I didn't know exactly": Gender identity development, expression and affirmation in youth who access gender affirming medical care

Background: Research about gender identity development is still in its infancy, especially among youth who experience gender dysphoria and are accessing gender-affirming medical care. Aims: This article contributes to the literature on how gender identity and gender dysphoria is experienced, expressed and addressed by youth who have started, or are just about to start, a gender-affirming medical intervention. Methods: The project draws from qualitative interviews with 36 trans children and youth of different ages and stages of puberty. The data were collected in three specialized Canadian clinics that offer gender-affirming care and they were analyzed through inductive thematic analysis. Results: Two interlinked dimensions of the youth's lives allow meaning-making of their gender identity: 1) internal or personal and 2) interactional or social processes. Careful analysis reveals three gender identity development pathways that may be taken by youth, from early questioning to the affirmation of their gender identity. A discussion of current models of gender identity development and their limitations concludes the article.

Community-Engaged Development, Implementation, and Evaluation of an Interprofessional Education Workshop on Gender-Affirming Care

Background: Transgender/nonbinary (trans/NB) patients face stigma in health care settings. Health care professionals' training on trans/NB issues has historically been lacking. Interprofessional education (IPE) provides an opportunity to improve knowledge and attitudes across health care professions. The purpose of this study was to: (a) describe the development and implementation of an IPE workshop on gender-affirming care through a trans/NB community-academic partnership and (b) examine the impact of the workshop on student knowledge and attitudes. Methods: The workshop included a slide presentation on basic terminology and concepts, video clips of trans/NB patient-provider interactions, facilitated discussions of affirming practices, and a trans/NB panel. Nonparametric statistical analysis of pre- and post-survey data from 58 workshop participants measured changes in student knowledge and attitudes. Findings: Students demonstrated statistically significant improvements in knowledge (t=-12.72; p<0.01) and interpersonal comfort (t=-2.06; p<0.05) as well as sex and gender beliefs (t=-3.06; p<0.05) on subscales from the Transgender Attitudes & Beliefs Scale. The results demonstrated no differences on the human value subscale (t=-0.69; p=0.49) or on health care professional questions (t=-1.23; p=0.23). Conclusions: A community-academic partnership developed and implemented this brief interactive educational intervention, which can improve both knowledge and attitudes about trans/NB individuals' health among health professional students.
