Cross-sex Hormones and Acute Cardiovascular Events in Transgender Persons: A Cohort Study

Changes in Blood Lipids Following Initiation of Gender Affirming Hormone Therapy: A Systematic Review and Meta-Analysis

Aim

The aim of this study was to conduct a systematic review and meta-analysis of changes in low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), total cholesterol, and triglycerides following initiation of feminizing or masculinizing gender affirming hormone therapy (GAHT).

Methods

A search of Ovid MEDLINE, Embase, Web of Science, SCOPUS, and CINAHL databases identified potentially relevant articles published from 1990 through 2024. Both observational and randomized trials of adults receiving feminizing or masculinizing GAHT with baseline and follow-up measures were included. Articles were reviewed for eligibility using Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020 guidelines. The risk of bias in each study was quantified using the NHLBI Study Quality Assessment Tool for Before-After (Pre-Post) Studies with No Control Group. Random effects models were used to compute the before-and-after meta-differences in mean values for each parameter along with the I2 statistic to assess heterogeneity of results.

Results

Thirty-five studies met the criteria for inclusion in the meta-analysis. Masculinizing GAHT was associated with significant changes in serum lipids from baseline up through the 60-month timepoint with meta-difference of means (95% CI) estimates of 26.2mg/dL (23.3,29.0) for LDL-C, 26.1mg/dL (22.8,29.4) for total cholesterol, 30.7mg/dL (6.9,54.6) for triglycerides and -9.4mg/dL (-12.1, -6.7) for HDL-C. Studies evaluating the effects of feminizing GAHT on balance demonstrated no notable changes in HDL-C or triglycerides while the results for LDL-C and total cholesterol were inconsistent. Heterogeneity of results ranged from minimal (I2 = 0%) to substantial (I2 = 90%).

Conclusions

While the results for transfeminine individuals on GAHT appear somewhat reassuring, transmasculine patients receiving testosterone may benefit from closer monitoring of lipid profiles.

Gender-affirming hormone therapy and cardiovascular health in transgender adults

A growing number of people identify as transgender and gender non-binary in the USA and worldwide. Concomitantly, an increasing number of patients are receiving gender-affirming hormone therapy (GAHT) to achieve gender congruence. GAHT has far-ranging effects on clinical and subclinical markers of cardiovascular risk. Transgender patients also appear to be at higher risk for cardiovascular diseases compared to their cisgender peers and the impact of gender-affirming therapy on cardiovascular health is unclear. Studies on the effect of GAHT on cardiovascular outcomes are confounded by differences in GAHT regimens and methodological challenges in a diverse and historically hard-to-reach population. Current cardiovascular guidelines do not incorporate gender identity and hormone status into risk stratification and clinical decision-making. In this review, we provide an overview on the cardiometabolic impact and clinical considerations of GAHT for cardiovascular risk in transgender patients.

The association of gender-affirming hormone therapy duration and body mass index on bone mineral density in gender diverse adults

Introduction

Feminizing and masculinizing gender-affirming hormone therapy (fGAHT, mGAHT) results in bone mineral density (BMD) maintenance or improvement over time in transgender and gender diverse (TGD) adults. Mostly European TGD studies have explored GAHT's impact on BMD, but the association of BMI and BMD in TGD adults deserves further study.

Objective

To determine whether GAHT duration or BMI are associated with BMD and Z-scores among TGD young adults.

Methods

Cross-sectional study of nonsmoking TGD adults aged 18-40 years without prior gonadectomy or gonadotropin-releasing hormone agonist (GnRHa) therapy taking GAHT for > 1 year. BMD and Z-scores were collected from dual-energy x-ray absorptiometry. Associations between femoral neck, total hip, and lumbar spine BMDs and Z-scores and the predictors, GAHT duration and BMI, were estimated using linear regression.

Results

Among 15 fGAHT and 15 mGAHT, mean BMIs were 27.6 +/- standard deviation (SD) 6.4 kg/m2 and 25.3 +/- 5.9 kg/m2, respectively. Both groups had mean BMDs and Z-scores within expected male and female reference ranges at all three sites. Higher BMI among mGAHT was associated with higher femoral neck and total hip BMDs (femoral neck: β = 0.019 +/- standard error [SE] 0.007 g/cm2, total hip: β = 0.017 +/- 0.006 g/cm2; both p < 0.05) and Z-scores using male and female references. GAHT duration was not associated with BMDs or Z-scores for either group.

Conclusions

Z-scores in young, nonsmoking TGD adults taking GAHT for > 1 year, without prior gonadectomy or GnRHa, and with mean BMIs in the overweight range, were reassuringly within the expected ranges for age based on male and female references. Higher BMI, but not longer GAHT duration, was associated with higher femoral neck and total hip BMDs and Z-scores among mGAHT. Larger, prospective studies are needed to understand how body composition changes, normal or low BMIs, and gonadectomy affect bone density in TGD adults.

Considerations in gender-affirming hormone therapy in transgender and gender diverse patients undergoing liver transplantation

Liver transplantation is lifesaving for patients with end-stage liver disease. Similar to the role of transplantation for patients with end-stage liver disease, gender-affirming hormone therapy (GAHT) can be lifesaving for transgender and gender diverse (TGGD) patients who experience gender dysphoria. However, management of such hormone therapy during the perioperative period is unknown and without clear guidelines. Profound strides can be made in improving care for TGGD patients through gender-affirming care and appropriate management of GAHT in liver transplantation. In this article, we call for the transplant community to acknowledge the integral role of GAHT in the care of TGGD liver transplant candidates and recipients. We review the current literature and describe how the transplant community is ethically obligated to address this health care gap. We suggest tangible steps that clinicians may take to improve health outcomes for this minoritized patient population.

Venous Thromboembolism and Estrogen-Containing Gender-Affirming Hormone Therapy

Gender-affirming therapy involves the use of hormones to develop the physical characteristics of the identified gender and suppressing endogenous sex hormone production. Venous thromboembolism (VTE) is a known risk of exogenous estrogen therapy, and while evidence of VTE risk among transgender women using modern gender-affirming hormone therapy (GAHT) is still emerging, it is thought to affect up to 5% of transgender women. Historically, GAHT was associated with a high risk of VTE; however, modern preparations are less thrombogenic mainly due to significantly lower doses used as well as different preparations. This review presents the available literature regarding the following four topics: (1) risk of VTE among transgender women receiving estradiol GAHT, (2) how the route of administration of estradiol affects the VTE risk, (3) perioperative management of GAHT, (4) VTE risk among adolescents on GAHT. There is a need for large, longitudinal studies of transgender women using GAHT to further characterize VTE risk and how this is affected by factors such as patient age, duration of GAHT use, tobacco use, body mass index, and comorbidities. Future studies in these areas could inform the development of clinical guidelines to improve the care of transgender people.

Neurological care for LGBT+ people

Sexual and gender minority (LGBT+) people face unique health disparities that must be considered by health-care providers to ensure equitable and inclusive care. Although traditionally LGBT+ health has not been integrated into neurology training, sexual orientation and gender identity have direct relevance to neurological health, driven by both systemic and interpersonal factors. In this Review, we summarize the evidence for associations between sexual orientation and gender identity with the prevalence and outcomes of various neurological conditions, including neurodegenerative diseases, epilepsy, stroke and neurodevelopmental disorders, among others. We describe important clinical considerations pertaining to LGBT+ people and recommend language and practices to promote inclusive care, as well as highlight gaps in need of further research and possible strategies to minimize these, including systematic collection of sexual orientation and gender identity and use of inclusive language.

Gender-Affirming Facial Surgery: Lower Third of the Face

This article is intended to give the reader an overview of facial gender-affirming procedures applicable to the lower face and neck. A review of facial analysis in the context of masculine versus feminine facial features and the contributions of both soft tissue and bone to this anatomy is provided. The use of systematic facial evaluation and patient-driven concerns as a guide for presurgical planning is reviewed. Detailed descriptions of the unique surgical interventions to feminize the soft tissues and the skeletal framework of the lower face and neck are provided.

Musculoskeletal and cardiovascular considerations for transgender athletes

OBJECTIVE

Participation in athletics is essential for the overall well-being of transgender athletes and should be included as part of gender-affirming care. Surveys show physicians and athletic trainers want to provide appropriate care for transgender athletes but lack the proper knowledge and training to do so. Gender Affirming Hormone Therapy (GAHT) is part of gender-affirming care, yet the effects of GAHT on the cardiovascular and musculoskeletal health of transgender athletes is not well-understood. The purpose of this review was to discuss important musculoskeletal and cardiovascular considerations unique to transgender athletes and improve physician understanding in caring for transgender athletes.

METHODS

A representative selection of literature on the effects of GAHT on cardiovascular and musculoskeletal health was included in this review.

RESULTS

Estrogen therapy may increase the risk of venous thromboembolism (VTE) and stroke, and decrease blood pressure levels among transgender women, while studies on lipid profile are inconsistent among both transgender men and women. Transgender women receiving GAHT may also be at greater risk for bone fracture and ligamentous injuries.

CONCLUSION

Exercise is essential for the well-being of transgender individuals and special considerations regarding the cardiovascular and musculoskeletal health of transgender athletes should be incorporated into standard medical education. Educational programs for transgender patients and their support team should focus on preventative measures that can be taken to reduce the risk of adverse musculoskeletal and cardiovascular events. The PPE is an invaluable tool available to physicians to monitor the health and safety of transgender athletes and should be regularly updated as research on the health of transgender individuals continues to grow. Longitudinal and prospective studies should examine the effects of GAHT on the musculoskeletal and cardiovascular health of transgender athletes. Lastly, health care providers play an important role in the advancement of gender-neutral policies.

Estrogen's sex-specific effects on ischemic cell death and estrogen receptor mRNA expression in rat cortical organotypic explants

Estrogens, such as the biologically active 17-β estradiol (E2), regulate not only reproductive behaviors in adults, but also influence neurodevelopment and neuroprotection in both females and males. E2, contingent upon the timing and concentration of the therapy, is neuroprotective in female and male rodent models of stroke. In Vivo studies suggest that E2 may partially mediate this neuroprotection, particularly in the cortex, via ERα. In Vitro studies, utilizing a chemically induced ischemic injury in cortical explants from both sexes, suggest that ERα or ERβ signaling is needed to mediate the E2 protection. Since we know that the timing and concentration of E2 therapy may be sex-specific, we examined if E2 (1 nM) mediates neuroprotection when female and male cortical explants are separately isolated from postnatal day (PND) 3-4 rat. Changes in basal levels ERα, ERβ, and AR mRNA expression are compared across early post-natal development in the intact cortex and the corresponding days in vitro (DIV) for cortical explants. Following ischemic injury at 7 DIV, cell death and ERα, ERβ and AR mRNA expression was compared in female and male cortical explants. We provide evidence that E2-mediated protection is maintained in isolated cortical explants from females, but not male rats. In female cortical explants, the E2-mediated protection at 24 h occurs secondarily to a blunted transient increase in ERα mRNA at 12 h. These results suggest that cortical E2-mediated protection is influenced by sex and supports data to differentially treat females and males following ischemic injury.

The impact of gender-affirming hormone therapy on nutrition-relevant biochemical measures

Gender-affirming hormone therapy carries the potential risk for shifts in biochemical markers that may impact cardiometabolic, hematologic, hepatic, and renal health. The critical evaluation of biochemical data is an integral part of a comprehensive nutrition assessment; therefore, nutrition professionals should be aware of shifts that are expected during the course of masculinizing and feminizing hormone therapy. Changes in important biochemical values along with binary sex-specific standards for interpreting laboratory data can pose significant challenges for nutrition professionals working with transgender and gender-diverse patients who receive gender-affirming hormone therapy. Overall, research on the biochemical impact of masculinizing and feminizing hormone therapy is nascent and limited. Methodologies and outcomes measured are heterogenous across studies, introducing complexities that impede researchers from drawing definitive conclusions. In light of these limitations, this narrative review aims to describe the potential implications of masculinizing and feminizing hormone therapy regimens on biochemical measures that may influence nutrition strategies and interventions to promote optimal health.

Use of hormones and risk of venous thromboembolism

•The risk of venous thromboembolism (VTE) is not increased in women using long-acting reversible contraceptive methods (LARCs) with progestogens. •Oral contraceptives with levonorgestrel or norgestimate confer half the risk of VTE compared to oral contraceptives containing desogestrel, gestodene or drospirenone. •Progestogen-only pills do not confer an increased risk of VTE. •Women using transdermal contraceptive patches and combined oral contraceptives (COCs) are at an approximately eight times greater risk of VTE than non-users of hormonal contraceptives (HCs), corresponding to 9.7 events per 10,000 women/years. •Vaginal rings increase the risk of VTE by 6.5 times compared to not using HC, corresponding to 7.8 events per 10,000 women/years. •Several studies have demonstrated an increased risk of VTE in transgender individuals receiving hormone therapy (HT). •Hormone therapy during menopause increases the risk of VTE by approximately two times, and this risk is increased by obesity, thrombophilia, age over 60 years, surgery and immobilization. •The route of estrogen administration, the dosage and type of progestogen associated with estrogen may affect the risk of VTE in the climacteric. •Combined estrogen-progesterone therapy increases the risk of VTE compared to estrogen monotherapy. •Postmenopausal HT increases the risk of thrombosis at atypical sites.

The prevalence, phenotype and cardiometabolic risk of polycystic ovary syndrome in treatment-naïve transgender people assigned female at birth

PURPOSE

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women of reproductive age. We aimed to investigate the prevalence and phenotypic characteristics of PCOS in testosterone treatment-naïve transgender people assigned female at birth (AFAB), as well as to determine whether cardiometabolic risk factors vary based on the presence of PCOS and its components.

METHODS

Evaluation of 112 testosterone treatment-naïve transgender adults AFAB for PCOS and its individual components, including androgen excess, ovulatory dysfunction and polycystic ovarian morphology (PCOM).

RESULTS

In our cohort, 79.5% of transgender individuals AFAB had at least one component of PCOS. The prevalence of PCOS was 38.4% (43/112). Phenotype C was the most common phenotype (17.8%), followed by phenotype B (10.7%). Transgender individuals AFAB with at least one component of PCOS had higher blood pressure (BP) measurements and higher fasting plasma glucose levels compared to those with none. Sixty-one subjects (54%) had hyperandrogenism (HA), with 20 (17.9%) having HA without other components of PCOS. When compared to those without HA, transgender individuals AFAB with HA had higher body mass index (BMI), BP, triglyceride and lower HDL-cholesterol levels.

CONCLUSION

PCOS and androgen excess appear to be prevalent among transgender people AFAB. Transgender individuals AFAB with HA or PCOS may exhibit an unfavorable cardiometabolic risk profile compared to those without any PCOS component. Assessment of androgen excess and the specific components of PCOS at baseline could inform long-term management.

Neurological Health in Sexual and Gender Minority Individuals

Despite representing a significant proportion of the U.S. population, there is a paucity of population-based research on the health status and health needs of sexual and gender minority (SGM) individuals in neurology. Compared with heterosexual peers, some SGM populations have a higher burden of chronic health conditions. In parallel, SGM individuals are more likely to experience stigma and discrimination producing psychological distress, which may contribute to and be compounded by reduced health care access and utilization. In this narrative review, we summarize the existing literature on common neurological health conditions such as stroke, headache, epilepsy, movement disorders, and traumatic brain injury through the lens of intersection of SGM identity. Special focus is attuned to social determinants of health and gender-affirming hormonal therapy. Given the limitations in the available literature, there is an urgent unmet need for datasets that include sexual orientation and gender identity information, as well as funding for research that will characterize the prevalence of neurological conditions, unique risk factors, and health outcomes in SGM populations. In the health care community, providers should address deficiencies in their professional training and integrate inclusive language into their clinical skillset to build trust with SGM patients. There is an opportunity in neurology to proactively engage SGM communities, collaborate to remove barriers to care, promote resilience, and develop targeted interventions to ensure high-quality, culturally competent care for SGM populations to improve neurological health for all.

A Holistic Framework for the Evaluation of Kidney Function in a Gender-Diverse Landscape

The most commonly used equations to estimate glomerular filtration rate incorporate a binary male-female sex coefficient, which has important implications for the care of transgender, gender-diverse, and nonbinary (TGD) people. Whether "sex assigned at birth" or a binary "gender identity" is most appropriate for the computation of estimated glomerular filtration rate (eGFR) is unknown. Furthermore, the use of gender-affirming hormone therapy (GAHT) for the development of physical changes to align TGD people with their affirmed gender is increasingly common, and may result in changes in serum creatinine and cystatin C, the biomarkers commonly used to estimate glomerular filtration rate. The paucity of current literature evaluating chronic kidney disease (CKD) prevalence and outcomes in TGD individuals on GAHT makes it difficult to assess any effects of GAHT on kidney function. Whether alterations in serum creatinine reflect changes in glomerular filtration rate or simply changes in muscle mass is unknown. Therefore, we propose a holistic framework to evaluate kidney function in TGD people. The framework focuses on kidney disease prevalence, risk factors, sex hormones, eGFR, other kidney function assessment tools, and the mitigation of health inequities in TGD people.

Diagnosis and Management of Cerebral Venous Thrombosis: A Scientific Statement From the American Heart Association

Cerebral venous thrombosis accounts for 0.5% to 3% of all strokes. The most vulnerable populations include young individuals, women of reproductive age, and patients with a prothrombotic state. The clinical presentation of cerebral venous thrombosis is diverse (eg, headaches, seizures), requiring a high level of clinical suspicion. Its diagnosis is based primarily on magnetic resonance imaging/magnetic resonance venography or computed tomography/computed tomographic venography. The clinical course of cerebral venous thrombosis may be difficult to predict. Death or dependence occurs in 10% to 15% of patients despite intensive medical treatment. This scientific statement provides an update of the 2011 American Heart Association scientific statement for the diagnosis and management of cerebral venous thrombosis. Our focus is on advances in the diagnosis and management decisions of patients with suspected cerebral venous thrombosis. We discuss evidence for the use of anticoagulation and endovascular therapies and considerations for craniectomy. We also provide an algorithm to optimize the management of patients with cerebral venous thrombosis and those with progressive neurological deterioration or thrombus propagation despite maximal medical therapy.

Bidirectional pharmacokinetics of doravirine, tenofovir, and feminizing hormones in transgender women (IDentify): A randomized crossover trial

Transgender women may have concerns of drug interactions between feminizing hormone therapy (FHT) and antiretrovirals, leading to nonadherence. This randomized, three-period crossover, open-label, phase I trial assessed the effects of doravirine (DOR) and tenofovir disoproxil fumarate (TDF) on the pharmacokinetics (PKs) of estradiol, spironolactone, and total testosterone and vice versa in healthy transgender women. Volunteers were randomized 1:1 into two sequences containing three treatment groups (DOR, lamivudine [3TC], and TDF alone; estradiol, spironolactone, and placebo; and DOR/3TC/TDF, estradiol, and spironolactone). Eight subjects enrolled in the study and six had completed all study periods. The geometric mean ratios for DOR area under the concentration-time curve from zero to last measured concentration (AUC0-last ), maximum concentration (Cmax ), and concentration at 24 h (C24 ) were similar. However, tenofovir (TFV) AUC0-last , Cmax , and C24 moderately increased by 14%-38%. Last, estradiol AUC0-last , Cmax , and C24 were increased by 10%-13%. Whereas most 90% confidence intervals did not meet the bioequivalence bounds of 80%-125%, the point estimates fell within the intervals. Log-transformed DOR, TFV, and estradiol PK parameters computed with and without co-administration were not statistically different (p > 0.05). There were no serious adverse events. There is not a clinically significant impact of FHT on DOR/TFV PKs. Similarly, there is no observed impact on estradiol PKs and total testosterone following use of DOR/3TC/TDF.

Understanding how primary care providers report discussing substance use with transgender and gender diverse patients

OBJECTIVES

To explore how primary care providers report discussing substance use with transgender and gender diverse (TGD) adult patients within the context of discussing gender-affirming interventions.

METHODS

Between March and April 2022, in-depth, semi-structured qualitative interviews were conducted with 15 primary care providers who care for TGD patients in the Northeastern US. Thematic analysis was used to analyze interview data and identify themes.

RESULTS

Two primary themes emerged among providers: 1) placing a focus on harm reduction, emphasizing reducing negative consequences of substance use, and 2) using access to gender-affirming interventions as an incentive for patients to change their substance use patterns.

CONCLUSIONS

Focusing on harm reduction can emphasize reducing potential adverse outcomes while working with TGD patients towards their gender-affirmation goals. Future research should explore varying approaches to how substance use is discussed with TGD patients, as well as the interpretation of gender-affirming clinical guidelines.

PRACTICE IMPLICATIONS

Findings from this study indicate a need for enhancing provider knowledge around the appropriate application of gender-affirming care guidelines. Investing in training efforts to improve gender-affirming care is critical for encouraging approaches that prioritize harm reduction and do not unnecessarily prevent access to gender-affirming interventions.

2024 Heart Disease and Stroke Statistics: A Report of US and Global Data From the American Heart Association

BACKGROUND

The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Considerations for Gender-Affirming Hormonal and Surgical Care Among Transgender and Gender Diverse Adolescents and Adults With Congenital Heart Disease

BACKGROUND

Transgender and gender diverse (TGD) individuals and long-term survivors with adult congenital heart disease (ACHD) are both growing populations with specialized needs. No studies assess temporal trends or evaluate the care of TGD individuals with ACHD.

METHODS AND RESULTS

Meetings between congenital cardiology and gender-affirming care specialists identified unique considerations in TGD individuals with ACHD. A retrospective chart review was then performed to describe patient factors and outpatient trends in those with an ACHD diagnosis undergoing gender-affirming hormonal or surgical care (GAHT/S) at 1 adult and 1 pediatric tertiary care center. Thirty-three TGD individuals with ACHD were identified, 21 with a history of GAHT/S. Fourteen (66%) had moderate or complex ACHD, 8 (38%) identified as transgender male, 9 (43%) transgender female, and 4 (19%) other gender identities. Three had undergone gender-affirming surgery. There were zero occurrences of the composite end point of unplanned hospitalization or thrombotic event over 71.1 person-years of gender-affirming care. Median age at first gender-affirming appointment was 16.8 years [interquartile range 14.8-21.5]. The most common treatment modification was changing estradiol administration from oral to transdermal to reduce thrombotic risk (n=3). An increasing trend was observed from zero TGD patients with ACHD attending a gender diversity appointment in 2012 to 14 patients in 2022.

CONCLUSIONS

There is a growing population of TGD patients with ACHD and unique medical and psychosocial needs. Future studies must fully evaluate the reassuring safety profile observed in this small cohort. We share 10 actionable care considerations for providers with a goal of overseeing a safe and fulfilling gender transition across all TGD patients with ACHD.

Cardiovascular disease in transgender people: a systematic review and meta-analysis

OBJECTIVE

Hormone therapy in transgender people might be associated with an increased risk of cardiovascular disease (CVD). We aimed to investigate whether the risk of CVD is increased in transgender people compared with people of the same birth sex.

DESIGN AND METHODS

PubMed, Cochrane, Embase, and Google Scholar were searched until July 2022. Studies evaluating cardiovascular events in transgender women or men were included. Primary outcomes were stroke, myocardial infarction (MI), and venous thromboembolism (VTE). The risk for transgender women versus cisgender men and for transgender men versus cisgender women was analysed through random-effects meta-analysis.

RESULTS

Twenty-two studies involving 19 893 transgender women, 14 840 transgender men, 371 547 cisgender men, and 434 700 cisgender women were included. The meta-analysis included 10 studies (79% of transgender women and 76% of transgender men). In transgender women, incidence of stroke was 1.8%, which is 1.3 (95% confidence interval [CI], 1.0-1.8) times higher than in cisgender men. Incidence of MI was 1.2%, with a pooled relative risk of 1.0 (95% CI, 0.8-1.2). Venous thromboembolism incidence was 1.6%, which is 2.2 (95% CI, 1.1-4.5) times higher. Stroke occurred in 0.8% of transgender men, which is 1.3 (95% CI, 1.0-1.6) times higher compared with cisgender women. Incidence of MI was 0.6%, with a pooled relative risk of 1.7 (95% CI, 0.8-3.6). For VTE, this was 0.7%, being 1.4 (95% CI, 1.0-2.0) times higher.

CONCLUSIONS

Transgender people have a 40% higher risk of CVD compared with cisgender people of the same birth sex. This emphasizes the importance of cardiovascular risk management. Future studies should assess the potential influence of socio-economic and lifestyle factors.

Impact of age and sex on myelopoiesis and inflammation during myocardial infarction

Of all the different risk factors known to cause cardiovascular disease (CVD), age and sex are considered to play a crucial role. Aging follows a continuum from birth to death, and therefore it inevitably acts as a risk for CVD. Along with age, sex differences have also been shown to demonstrate variations in immune system responses to pathological insults. It has been widely perceived that females are protected against myocardial infarction (MI) and the protection is quite apparent in young vs. old women. Acute MI leads to changes in the population of myeloid and lymphoid cells at the injury site with myeloid bias being observed in the initial inflammation and the lymphoid in the late-resolution phases of the pathology. Multiple evidence demonstrates that aging enhances damage to various cellular processes through inflamm-aging, an inflammatory process identified to increase pro-inflammatory markers in circulation and tissues. Following MI, marked changes were observed in different sub-sets of major myeloid cell types viz., neutrophils, monocytes, and macrophages. There is a paucity of information regarding the tissue and site-specific functions of these sub-sets. In this review, we highlight the importance of age and sex as crucial risk factors by discussing their role during MI-induced myelopoiesis while emphasizing the current status of myeloid cell sub-sets. We further put forth the need for designing and executing age and sex interaction studies aimed to determine the appropriate age and sex to develop personalized therapeutic strategies post-MI.

Approach to the Patient: Hormonal Therapy in Transgender Adults With Complex Medical Histories

While endocrinologists continue to initiate gender-affirming hormone therapy (GAHT) in healthy transgender and gender diverse (TGD) patients, they may also encounter more TGD patients in their clinics with complex medical histories that influence the patient-provider shared decision-making process for initiating or continuing GAHT. The purpose of this Approach to the Patient article is to describe management considerations in 2 adults with thromboembolic disease and 2 adults with low bone mineral density in the setting of feminizing and masculinizing GAHT.

The Impact of Gender-Affirming Hormone Therapy on Physical Performance

CONTEXT

The inclusion of transgender people in elite sport has been a topic of debate. This narrative review examines the impact of gender-affirming hormone therapy (GAHT) on physical performance, muscle strength, and markers of endurance.

EVIDENCE ACQUISITION

MEDLINE and Embase were searched using terms to define the population (transgender), intervention (GAHT), and physical performance outcomes.

EVIDENCE SYNTHESIS

Existing literature comprises cross-sectional or small uncontrolled longitudinal studies of short duration. In nonathletic trans men starting testosterone therapy, within 1 year, muscle mass and strength increased and, by 3 years, physical performance (push-ups, sit-ups, run time) improved to the level of cisgender men. In nonathletic trans women, feminizing hormone therapy increased fat mass by approximately 30% and decreased muscle mass by approximately 5% after 12 months, and steadily declined beyond 3 years. While absolute lean mass remains higher in trans women, relative percentage lean mass and fat mass (and muscle strength corrected for lean mass), hemoglobin, and VO2 peak corrected for weight was no different to cisgender women. After 2 years of GAHT, no advantage was observed for physical performance measured by running time or in trans women. By 4 years, there was no advantage in sit-ups. While push-up performance declined in trans women, a statistical advantage remained relative to cisgender women.

CONCLUSION

Limited evidence suggests that physical performance of nonathletic trans people who have undergone GAHT for at least 2 years approaches that of cisgender controls. Further controlled longitudinal research is needed in trans athletes and nonathletes.

A case report of myocardial infarction in a young transgender man with testosterone therapy: raising awareness on healthcare issues in the transgender community and a call for further research

Background

People who are transgender may utilize masculinizing or feminizing gender-affirming hormonal therapy. Testosterone and oestrogen receptors are expressed throughout the cardiovascular system, yet the effects of these therapies on cardiovascular risk and outcomes are largely unknown. We report the case of a young transgender man with no discernible cardiovascular risk factors presenting with an acute coronary syndrome.

Case summary

A 31-year-old transgender man utilizing intramuscular testosterone masculinizing gender-affirming hormonal therapy presented with central chest pain radiating to the left arm. He had no past medical history of hypertension, dyslipidaemia, diabetes, or smoking. Electrocardiography demonstrated infero-septal ST depression, and high-sensitivity troponin-I was elevated and increased to 19 686 ng/L. He was diagnosed with a non-ST-segment elevation myocardial infarction. Inpatient coronary angiography confirmed a critical focal lesion in the mid right coronary artery, which was managed with two drug-eluting stents. Medical management (i.e. aspirin, ticagrelor, atorvastatin, ramipril, and bisoprolol) and surveillance of residual plaque disease evident in the long tubular left main stem, proximal left anterior descending, and proximal circumflex vessels was undertaken. The masculinizing gender-affirming hormonal therapy was continued.

Discussion

Despite a greater awareness of the potential risk of increased cardiovascular disease in transgender people, the fundamental lack of data regarding cardiovascular outcomes in transgender people may be contributing to healthcare inequalities in this population. We must implement better training, awareness, and research into transgender cardiovascular health to facilitate equitable and evidence-based outcomes.

Exploring Hormone Therapy Effects on Reproduction and Health in Transgender Individuals

Transgender individuals often face elevated mental health challenges due to gender dysphoria, but gender-affirming treatments such as surgery and hormone therapy have been linked to significant improvements in mental well-being. The potential influence of time and circadian rhythms on these treatments is prevalent. The intricate interplay between hormones, clock genes, and fertility is profound, acknowledging the complexity of reproductive health in transgender individuals. Furthermore, risks associated with gender-affirming hormonal therapy and potential complications of puberty suppression emphasize the importance of ongoing surveillance for these patients and the need of fertility preservation and family-building options for transgender individuals. This narrative review delves into the intricate landscape of hormone therapy for transgender individuals, shedding light on its impact on bone, cardiovascular, and overall health. It explores how hormone therapy affects bone maintenance and cardiovascular risk factors, outlining the complex interplay of testosterone and estrogen. It also underscores the necessity for further research, especially regarding the long-term effects of transgender hormones. This project emphasizes the critical role of healthcare providers, particularly obstetricians and gynecologists, in providing affirming care, calling for comprehensive understanding and integration of transgender treatments. This review will contribute to a better understanding of the impact of hormone therapy on reproductive health and overall well-being in transgender individuals. It will provide valuable insights for healthcare providers, policymakers, and transgender individuals themselves, informing decision-making regarding hormone therapy and fertility preservation options. Additionally, by identifying research gaps, this review will guide future studies to address the evolving healthcare needs of transgender individuals. This project represents a critical step toward addressing the complex healthcare needs of this population. By synthesizing existing knowledge and highlighting areas for further investigation, this review aims to improve the quality of care and support provided to transgender individuals, ultimately enhancing their reproductive health and overall well-being.

A mini-review of the evidence for cerebrovascular changes following gender-affirming hormone replacement therapy and a call for increased focus on cerebrovascular transgender health

Gender-affirming hormone replacement therapy (gaHRT) is an important step for many in the gender diverse community, associated with increased quality-of-life and lower self-reported scores of depression and anxiety. However, considering the interactions that the involved sex hormones have on vasculature (with oestrogen and testosterone demonstrating vasodilatory and vasoconstricting properties, respectively), it is important for transgender healthcare research to examine how the manipulation of these hormones interact with cerebrovascular structure and functioning. There is a stark lack of research in this area. This mini-review outlines the research suggesting a vascular impact of these sex hormones using evidence from a range of cohorts (e.g., menopause, polycystic ovary syndrome) and discusses the work that has been done into cerebrovascular changes following gaHRT. Finally, recommendations for future research into cerebrovascular health in transgender cohorts following gaHRT are outlined.

Impact of biological sex and sex hormones on molecular signatures of skeletal muscle at rest and in response to distinct exercise training modes

Substantial divergence in cardio-metabolic risk, muscle size, and performance exists between men and women. Considering the pivotal role of skeletal muscle in human physiology, we investigated and found, based on RNA sequencing (RNA-seq), that differences in the muscle transcriptome between men and women are largely related to testosterone and estradiol and much less related to genes located on the Y chromosome. We demonstrate inherent unique, sex-dependent differences in muscle transcriptional responses to aerobic, resistance, and combined exercise training in young and older cohorts. The hormonal changes with age likely explain age-related differential expression of transcripts. Furthermore, in primary human myotubes we demonstrate the profound but distinct effects of testosterone and estradiol on amino acid incorporation to multiple individual proteins with specific functions. These results clearly highlight the potential of designing exercise programs tailored specifically to men and women and have implications for people who change gender by altering their hormone profile.

Estrogen-Based Gender-Affirming Hormone Therapy and Subclinical Cardiovascular Disease in Transgender Women with HIV

Purpose: Transgender women (TW) are disproportionately affected by HIV infection and cardiovascular disease (CVD). This study evaluated whether estrogen-based gender-affirming hormone therapy (GAHT) in TW with HIV (TWH-GAHT) is associated with indices of subclinical CVD. Methods: Of the 40 HIV-seropositive persons enrolled, 20-60 years of age, on antiretroviral treatment with undetectable viral load, assessments were performed on 15 TWH; of these persons, 11 were GAHT treated. These TWH-GAHT were matched with HIV+ cisgender men and women based on age, ethnicity/race, body mass index, and antihypertensive medication use. Sex hormones, and cardiometabolic (waist circumference, blood pressure, insulin resistance, lipid profile, and C-reactive protein), vascular (flow-mediated dilation [FMD] and arterial stiffness), and proinflammatory measures were obtained. Results: TWH-GAHT displayed elevated estradiol and suppressed testosterone levels relative to normative ranges. Analyses indicated the TWH-GAHT displayed lower low-density lipoprotein compared with cisgender groups (p < 0.05). Although no difference was seen on FMD, the central augmentation index of aortic stiffness was higher in cisgender HIV+ women than cisgender HIV+ men (p < 0.05). No other group difference on subclinical CVD markers was observed. For TWH, partial correlations indicated associations of certain sex hormones with selected cardiometabolic outcomes and the inflammatory cytokine, interleukin-8. Conclusion: When well matched to HIV+ cisgender men and women, subclinical CVD pathophysiology did not appear elevated in TWH-GAHT, although tendencies emerged suggesting that some subclinical CVD indices may be higher, but others lower than cisgender groups. Longitudinal studies of TWH are needed to more precisely evaluate the moderating effect of GAHT on cardiometabolic pathophysiology.

Cardiovascular disease in transgender individuals

The population of people identifying as transgender has grown rapidly in recent years, resulting in a substantive increase in individuals obtaining gender-affirming medical care to align their secondary sex characteristics with their gender identity. This has established benefits for patients including improvements in gender dysphoria and psychosocial functioning, while reducing adverse mental health outcomes. Despite these potential advantages, recent evidence has suggested that gender-affirming hormone therapy (GAHT) may increase the risk of cardiovascular disease. However, owing to a paucity of research, the mechanisms underpinning these increased risks are poorly understood. Moreover, previous research has been limited by heterogenous methodologies, being underpowered, and lacking appropriate control populations. Consequently, the need for evidence regarding cardiovascular health in LGBTQ + individuals has been recognised as a critical area for future research to facilitate better healthcare and guidance. Recent research investigating the effect of transmasculine (testosterone) GAHT on cardiovascular disease risk points to testosterone effecting the nitric oxide pathway, triggering inflammation, and promoting endothelial dysfunction. Equivalent studies focussing on transfeminine (oestrogen) GAHT are required, representing a crucial area of future research. Furthermore, when examining the effects of GAHT on the vasculature, it cannot be ignored that there are multiple factors that may increase the burden of cardiovascular disease in the transgender population. Such stressors include major psychological stress; increased adverse health behaviours, such as smoking; discrimination; and lowered socioeconomic status; all of which undoubtedly impact upon cardiovascular disease risk and offers the opportunity for intervention.

Gender-affirming pharmacotherapy and additional health considerations: A contemporary review

BACKGROUND

Transgender and gender-diverse (TGD) individuals in the United States face health care disparities compounded with discrimination and limited access to necessary medical services. Gender-affirming interventions have been shown to mitigate gender dysphoria and psychiatric comorbidities, yet United States legislation limiting such interventions has increased. As medication experts, pharmacists can facilitate access to care and appropriate use of gender-affirming hormone therapy (GAHT) and educate other health care providers on best practices for caring for TGD individuals in a variety of settings.

OBJECTIVES

To provide pharmacists with a contemporary review of GAHT and associated medication-related concerns.

METHODS

We searched PubMed for articles published until December 2022. MeSH terms such as transgender, transsexual, gender diverse, gender variant, or gender nonconforming in combination with phrases like gender-affirming care, treatment, pharmacotherapy, or hormone therapy were used to capture desired articles.

RESULTS

Feminizing hormone therapy (FHT), such as estrogen and antiandrogen agents, increases female secondary sex characteristics while suppressing male secondary sex characteristics. Masculinizing hormone therapy (MHT) achieves male secondary sex characteristics and minimizes female secondary sex characteristics using testosterone. For both FHT and MHT, the choice of therapy and formulation ultimately involves the patient's treatment goals, preferences, and tolerability. GAHT has additional health considerations pertaining to renal drug dosing, fertility, cardiovascular, and cancer risks. Pharmacists may provide crucial guidance and education to both patients and health care providers regarding risks associated with GAHT.

CONCLUSION

Many pharmacists feel unprepared to help provide, manage, and optimize GAHT. For many TGD individuals, GAHT is medically necessary and a life-saving treatment. Therefore, pharmacists should be provided tools to close knowledge gaps and improve their ability to care for these patients. By offering a thorough updated overview of GAHT, pharmacists can gain confidence to provide appropriate care for this increasingly visible population.

Adherence to Gender Affirming Hormone Therapy in Transgender Adolescents and Adults: A Retrospective Cohort Study

CONTEXT

Transgender and gender diverse (TGD) individuals often seek gender-affirming hormone therapy (GAHT). While receipt of GAHT has been associated with improved well-being, the risk of GAHT discontinuation and its reasons are not well known.

OBJECTIVE

There were two main objectives: (1) To investigate the proportion of TGD individuals who discontinue therapy after an average of 4 years (maximum 19 years) since GAHT initiation; and (2) to explore reasons for GAHT discontinuation. This was a retrospective cohort study at academic centers providing care to TGD adolescents and adults. TGD individuals prescribed estradiol or testosterone between January 1, 2000, and January 1, 2019, were included. GAHT continuation was ascertained using a 2-phase process. In phase 1, Kaplan-Meier survival analyses were used to examine likelihood of GAHT discontinuation and compare discontinuation rates by age and sex assigned at birth. In phase 2, reasons for stopping GAHT were investigated by reviewing records and by contacting study participants who discontinued therapy. The main outcome measures were incidence and determinants of GAHT discontinuation.

RESULTS

Among 385 eligible participants, 231 (60%) were assigned male at birth and 154 (40%) were assigned female at birth. Less than one-third of participants (n = 121) initiated GAHT prior to their 18th birthday, constituting the pediatric cohort (mean age 15 years), and the remaining 264 were included in the adult cohort (mean age 32 years). In phase 1, 6 participants (1.6%) discontinued GAHT during follow-up, and of those only 2 discontinued GAHT permanently (phase 2).

CONCLUSION

GAHT discontinuation is uncommon when therapy follows Endocrine Society guidelines. Future research should include prospective studies with long-term follow-up of individuals receiving GAHT.

Transgender-related stigma and gender minority stress-related health disparities in Aotearoa New Zealand: hypercholesterolemia, hypertension, myocardial infarction, stroke, diabetes, and general health

Background

Research has found that transgender-related enacted stigma-including discrimination, harassment, violence, cyberbullying, community rejection, and conversion efforts-is associated with negative mental health among transgender people. Transgender people also experience physical health disparities that could be due to chronic gender minority stress caused by stigma and prejudice.

Methods

We compared a large New Zealand national survey of transgender participants with the New Zealand Health Survey (NZHS) with age and ethnicity weightings on stress-related health conditions and indicators. We conducted multivariate logistic regression to test associations between transgender-related enacted stigma and physical health conditions and indicators, controlling for age, gender, ethnicity, gender affirming hormone use, and alcohol and tobacco use.

Findings

Transgender participants had a greater likelihood of ever having hypertension (63%, 95% CI 41%-89%), a myocardial infarction (98%, 6%-271%), a stroke (104%, 2%-311%), hypercholesteremia 148% (114%-188%), and current poor or fair general health (128%, 107%-151%). There were no significant differences for diabetes. Compared with those scoring at the 10th percentile on transgender-related enacted stigma, those at the 90th percentile were more likely to have had hypertension (81%, 36%-140%), hypercholesteremia (54%, 20%-98), and poor/fair health (75%, 45%-110%).

Interpretation

We found large disparities for stress-related physical health conditions and indicators, and transgender people who experienced higher transgender-related enacted stigma had a significantly increased prevalence of these negative outcomes. Our findings highlight the need for health professionals to consider gender minority stress and for interventions and policy/law reforms to address transgender-related stigma.

Hemostatic considerations for gender affirming care

Gender dysphoria or gender incongruence is defined as "persons that are not satisfied with their designated gender" [1]. The awareness and evidence-based treatment options available to this population have grown immensely over the last two decades. Protocols now include an Endocrine Society Clinical Practice Guideline [1] as well as the World Professional Association of Transgender Health Standards of Care (WPATH SOC) [2]. Hematologic manifestations, most notably thrombosis, are one of the most recognized adverse reactions to the hormones used for gender-affirming care. Therefore, hematologists are frequently consulted prior to initiation of hormonal therapy to help guide safe treatment. This review will focus on the scientific evidence related to hemostatic considerations for various gender-affirming therapies and serve as a resource to assist in medical decision-making among providers and patients.

Musculoskeletal health considerations for the transgender athlete

BACKGROUND

In addition to the familiar sports-related injuries and conditions experienced by cisgender athletes, transgender athletes may also face unique challenges to maintaining their musculoskeletal health. Encouraging sports medicine professionals to become familiar with accepted nomenclature and terminology related to transgender athletes will enable open communication on the field, in the athletic training facility, and office.

OBJECTIVE

Understanding contemporary medical and surgical gender-affirming treatments and the unique ways in which the musculoskeletal system might be affected by each - such as impairments in bone health, changes in ligamentous function and the potential increased risk for deep venous thromboembolism - is essential for provision of optimal musculoskeletal care to transgender athletes. Knowledge of the existing participation policies for transgender athletes is also key for enabling sports medicine professionals to effectively counsel athletes about the need for specialized protective equipment. Additionally, this knowledge is important for appropriately managing therapeutic use exemptions in the competitive sports setting.

CONCLUSION

This article provides an overview of the current accepted nomenclature, common gender-affirming medical and surgical treatments, unique musculoskeletal health considerations, and participation policies for transgender athletes.

The Importance of Safely Prescribing Hormones in the Transgender Community

The transgender community is rapidly growing, necessitating further education and understanding of their unique healthcare needs. Gender affirmation is a multistep process, which generally begins with transgender individuals socially transitioning by adopting a new name, pronouns, and appearance changes, such as hair and clothing, to express themselves. Additional gender affirmation treatment can be achieved through medical therapy with hormones and surgical intervention. Here, we report the case of an 18-year-old transgender man who presented to his primary care provider for a referral to initiate a medical transition with testosterone therapy. The patient practiced penetrative vaginal sex without contraception. The patient presented to the clinic eight months later with amenorrhea, thick coarse facial and body hair, oily skin, irritable moods, and a 20-lb weight gain. A pregnancy test revealed a positive result. A healthy baby girl was delivered at 40 weeks' gestation. This case demonstrates the importance of addressing contraception during the masculinization process in individuals who continue to practice vaginal intercourse. Healthcare providers should seek to establish a clinical environment free of discrimination and stigma to allow patients to feel comfortable describing potential triggers of gender dysphoria. We encourage medical practitioners to discuss all methods of birth control with transgender male patients and choose the contraceptive that best allows for a seamless medical transition.

Gender Disparities in Presentation, Management, and Outcomes of Acute Pulmonary Embolism

Pulmonary embolism (PE) is the third most common cause of cardiovascular death; however, gender disparities in PE remain understudied. All PE cases at a single institution between January 2013 and June 2019 were retrospectively reviewed. The clinical presentation, treatment modalities, and outcomes were compared between men and women using univariate and multivariate analyses adjusting for differences in baseline characteristics. A total of 1,345 patients were diagnosed with acute PE, of whom 56.3% were women (n = 757). Women had a significantly higher mean body mass index (29.4 vs 28.4) and a higher frequency of hypertension (53% vs 46%) and hormone use (6.6% vs 0%; all p <0.02). Men had a higher frequency of smoking (45% vs 33%, p <0.0001). Women had significantly lower PE severity index classifications (p = 0.0009). The rates of intensive care unit admission, vasopressor requirements, extracorporeal membrane oxygenation cannulation, and mechanical ventilation were similar between the genders. There was no significant difference in the treatment modality used between the genders. Although the risk factors and PE severity index class differed between the genders, there was no significant difference in resource utilization or treatment modality. Gender was also not a significant predictor of in-hospital mortality, moderate or severe bleeding, increased length of stay, or readmission in the study population.

Caring for Sexual and Gender Minority Adults with Cardiovascular Disease

This article summarizes existing evidence on cardiovascular disease (CVD) risk and CVD diagnoses among sexual and gender minority adults and provides recommendations for providing nursing care to sexual and gender minority adults with CVD. More research is needed to develop evidence-based strategies to care for sexual and gender minority adults with CVD.

Insights Into the Cardiomodulatory Effects of Sex Hormones: Implications in Transgender Care

Transgender individuals that undergo gender-affirming hormone therapy may experience discrimination in the health care setting with a lack of access to medical personnel competent in transgender medicine. Recent evidence suggests that gender-affirming hormone therapy is associated with an increased risk of cardiovascular diseases and cardiovascular risk factors. A recent statement from the American Heart Association reinforces the importance of cardiovascular-focused clinical management and the necessity for more research into the impact of gender-affirming hormone therapy. With this in mind, this review will highlight the known cardiovascular risk factors associated with gender-affirming hormone therapy and identify potential molecular mechanisms determined from the limited animal studies that explore the role of cross-sex steroids on cardiovascular risk. The lack of data in this understudied population requires future clinical and basic research studies to inform and educate clinicians and their transgender patient population to promote precision medicine for their care to improve their quality of life.

Thromboembolic risk with gender-affirming hormone therapy: potential role of global coagulation and fibrinolysis assays

Gender-affirming hormonal therapies are a critical component of the care of transgender individuals. Transgender people are commonly prescribed estrogen or testosterone to promote male-to-female or female-to-male transitions and to preserve gender-specific characteristics long-term. However, some exogenous hormones, especially certain estrogen preparations, are an established risk factor of thrombosis. As the number of individuals seeking gender-based care is rising, there is an urgent need to identify and characterize the mechanisms underlying hormone-associated thrombosis and incorporate this information into clinical algorithms for diagnosis and management. Herein, we discuss historical evidence on the incidence of thrombosis and changes in plasma composition in transgender and cisgender cohorts. We present 3 case studies to demonstrate knowledge gaps in thrombosis risk stratification and prediction tools. We also present data from in vitro coagulation and fibrinolysis assays and discuss how information from these kinds of assays may be used to help guide the clinical management of transgender individuals.

A Qualitative Examination of Tobacco Use and Smoking Cessation Among Gender Minority Adults

BACKGROUND

Despite the elevated prevalence of smoking among gender minority adults, little is known about the factors that influence their tobacco use and cessation.

PURPOSE

We identified and examined factors that influence tobacco use and cessation for gender minority adults, using a conceptual framework based on the Model of Gender Affirmation and Gender Minority Stress Model.

METHODS

Nineteen qualitative, semi-structured in-depth interviews were conducted with gender minority adults who smoke or no longer smoke and were recruited from the Portland, OR metropolitan area. Interviews were audio-recorded, professionally transcribed, and analyzed utilizing thematic analysis.

RESULTS

Four main themes were generated. Gender minority adults smoke to cope with general and gender minority-specific stressors. Smoking was described as a social behavior that was influenced and sustained by community and interpersonal relationships. Smoking cessation was motivated by health concerns (both general and gender minority-specific) and moderated by conducive life circumstances. Recommendations for tobacco cessation interventions highlighted the importance and role of social support. Participants expressed a strong desire for gender minority-specific tobacco cessation programs. There are unique and complex factors that contribute to the higher prevalence of smoking observed among gender minority adults.

CONCLUSIONS

Tobacco cessation interventions are urgently needed for this population and should be tailored to address the unique factors that impact tobacco use and cessation among gender minority people to increase the likelihood of success.

Implications of gender-affirming endocrine care for sports participation

Many transgender (trans) individuals utilize gender-affirming hormone therapy (GAHT) to promote changes in secondary sex characteristics to affirm their gender. Participation rates of trans people in sport are exceedingly low, yet given high rates of depression and increased cardiovascular risk, the potential benefits of sports participation are great. In this review, we provide an overview of the evidence surrounding the effects of GAHT on multiple performance-related phenotypes, as well as current limitations. Whilst data is clear that there are differences between males and females, there is a lack of quality evidence assessing the impact of GAHT on athletic performance. Twelve months of GAHT leads to testosterone concentrations that align with reference ranges of the affirmed gender. Feminizing GAHT in trans women increases fat mass and decreases lean mass, with opposite effects observed in trans men with masculinizing GAHT. In trans men, an increase in muscle strength and athletic performance is observed. In trans women, muscle strength is shown to decrease or not change following 12 months of GAHT. Haemoglobin, a measure of oxygen transport, changes to that of the affirmed gender within 6 months of GAHT, with very limited data to suggest possible reductions in maximal oxygen uptake as a result of feminizing GAHT. Current limitations of this field include a lack of long-term studies, adequate group comparisons and adjustment for confounding factors (e.g. height and lean body mass), and small sample sizes. There also remains limited data on endurance, cardiac or respiratory function, with further longitudinal studies on GAHT needed to address current limitations and provide more robust data to inform inclusive and fair sporting programmes, policies and guidelines.

Cardiovascular disease and feminizing gender-affirming hormone therapy: Implications for the provision of safe and lifesaving care

Sex recorded at birth, gender identity, and feminizing gender-affirming hormone therapy (fGAHT) likely contribute to cardiovascular disease (CVD) risk in transgender women. Understanding the interplay of these factors is necessary for the provision of safe, affirming, and lifesaving care. Among transgender women taking fGAHT, data show increases in CVD mortality and rates of myocardial infarction, stroke, and venous thromboembolism compared to reference populations, depending on study design and comparators. However, most studies are observational with a paucity of contextualizing information (e.g., dosing, route of administration, gonadectomy status), which makes it difficult to parse adverse fGAHT effects from confounders and interaction with known CVD risk factors (e.g., obesity, smoking, psychosocial and gender minority stressors). Increased CVD risk in transgender women points toward a need for greater attention to CVD management in this population including cardiology referral when indicated and additional research on the mechanisms and mediators of CVD risk.

Methodologic Approaches for Using Electronic Medical Records to Identify Experiences of Violence in Transgender and Cisgender People: Closing the Gap Between Diagnostic Coding and Lived Experiences

BACKGROUND

Transgender people experience extreme rates of violence and the electronic medical record (EMR) remains a mostly untapped resource to study the medical sequelae of such experiences.

OBJECTIVES

To develop and test a method for identifying experiences of violence using EMR data.

RESEARCH DESIGN

Cross-sectional study utilizing EMR data.

PEOPLE

Transgender and cisgender people seen at a regional referral center in Upstate New York.

MEASURES

We tested the utility of keyword searches and structured data queries to identify specific types of violence at various ages and in various contexts among cohorts of transgender and cisgender people. We compared the effectiveness of keyword searches to diagnosis codes and a screening question, "Are you safe at home?" using McNemar's test. We compared the prevalence of various types of violence between transgender and cisgender cohorts using the χ 2 test of independence.

RESULTS

Of the transgender cohort, 47% had experienced some type of violence versus 14% of the cisgender cohort (χ 2P value <0.001). Keywords were significantly more effective than structured data at identifying violence among both cohorts (McNemar P values all <0.05).

CONCLUSIONS

Transgender people experience extreme amounts of violence throughout their lives, which is better identified and studied using keyword searches than structured EMR data. Policies are urgently needed to stop violence against transgender people. Interventions are also needed to ensure safe documentation of violence in EMRs to improve care across settings and aid research to develop and implement effective interventions.

Emergency Medicine Considerations in the Transgender Patient

Transgender patients are at high risk for poor health outcomes and many harbor fear of healthcare settings secondary to prior discrimination, perceived sensationalism, clinician unfamiliarity, and unwanted exams. It is essential to approach transgender patients without judgement and with empathy. Asking open ended questions with explanation as to why your questions are pertinent to their specific care will help create rapport and trust. Through a basic working knowledge of terminology, types of hormone therapy, non-surgical techniques, garments, and surgical procedures typically encountered by such patients, and their respective potential side effects and complications, clinicians can provide quality care to transgender patients.

Prevalence of self-inflicted injuries among transgender and gender diverse adolescents and young adults compared to their peers: an examination of interaction with mental health morbidity

PURPOSE

Compare occurrence of self-inflicted injuries among transgender and gender diverse (TGD) youth to that of their cisgender peers while accounting for mental health diagnoses.

METHODS

Review of electronic health records from three integrated health care systems identified 1087 transfeminine and 1431 transmasculine adolescents and young adults. Poisson regression was used to calculate prevalence ratios comparing the proportion of TGD participants with at least one self-inflicted injury (a surrogate for suicide attempt) before index date (first evidence of TGD status) to the corresponding proportions in presumed cisgender male and female referents matched on age, race/ethnicity, and health plan. Interactions between gender identities and mental health diagnoses were assessed on multiplicative and additive scales.

RESULTS

TGD adolescents and young adults were more likely to have a self-inflicted injury, various mental health diagnoses, and multiple mental health diagnoses than their cisgender peers. The prevalence of self-inflicted injuries among TGD adolescents and young adults was high even in the absence of mental health diagnoses. Results were consistent with positive additive interaction and negative multiplicative interaction.

CONCLUSIONS

Universal suicide prevention efforts for all youth, including those with no mental health diagnoses, and more intensive suicide prevention efforts for TGD adolescents and young adults and those with at least one mental health diagnosis are warranted.

Cerebral Venous Thrombosis With Topical Estrogen-Progesterone Use in a Young Heterosexual Male: A Case Report

INTRODUCTION

Our report sheds light on the risk of topical hormonal use in relation to cerebral venous sinus thrombosis. We diagnosed our patient with cerebral venous thrombosis (CVT) using computed tomography venogram, then detailed history and examination were obtained, and thorough blood tests and imaging were done to exclude other causes of CVT like thrombophilias, infections, and malignancies.

CASE REPORT

Our patient is a 37-year-old heterosexual male, presented with headache only. The computed tomography venogram showed extensive CVT in the right internal jugular vein, sigmoid, transverse, and straight cerebral venous; detailed history and investigations suggest that his use of crushed oral contraceptive pills mixed with water topically on the scalp is the most important predisposing factor. This patient was managed with anticoagulants and is being followed in the clinic.

CONCLUSION

Oral hormonal use in contraceptives is a known risk factor for CVT. This case sheds light on the importance of topical hormonal use concerning CVT in females and males; it stresses the need for more studies in that area, as it is poorly studied.

Hormonal therapies in females with blood disorders: thrombophilia, thrombosis, hemoglobinopathies, and anemias

There is widespread use of gonadal steroid hormone therapy for a variety of indications throughout the reproductive and postreproductive lifespan. These therapies may have particular benefits and specific risk among those with blood disorders, including inherited or acquired bleeding disorders, thrombophilia, thrombosis, or anemia. This clinical review is intended to provide a guidance for counseling and management of adolescent and adult biologic females with thrombophilic risk factors and/or thrombosis who require hormonal therapy. In general, synthetic estrogens present in contraceptive products should be avoided in those with a personal or strong family history of thrombosis or thrombophilias. In contrast, natural estrogens present in formulations for climacteric symptom management do not need to be avoided, and vaginal or transdermal formulations are preferred. Likewise, transdermal estradiol is preferred for gender-affirming hormone therapy and requires individualized assessment in those at high risk of thrombosis. Progestogens (either synthetic progestins or naturally occurring progesterone) can be used safely in nearly all patients. There is minimal safety evidence among anticoagulated patients at risk for thrombosis, which requires a patient-specific approach when discussing hormone therapies.
