The effects of gender-affirming hormone therapy on cardiovascular and skeletal health: A literature review

Cerebrovascular Health Among Sex- and Gender-Diverse People: A Narrative Review

Purpose of Review

Sex and gender diversity includes people who are intersex, transgender, and nonbinary. Americans are identifying as sex and gender diverse (SGD) in increasing numbers. Although data are limited on the diagnosis and management of stroke in SGD communities, the current literature suggests that there may be unique health needs among these marginalized populations.

Recent Findings

Health disparities and community-specific stressors may influence the frequency of stroke and traditional cerebrovascular disease risk factors among SGD people. In addition, transgender and gender-diverse people have higher rates of atypical stroke risk factors, such as sexually transmitted infections and an increased mental health burden. The adverse effects of some gender-affirming therapies can increase the rates of stroke, particularly in transfeminine people who use long-term estrogen as part of their medical gender transition. Decisions to discontinue hormonal therapy after stroke should be weighed against the psychological risks of doing so. In addition, some commonly prescribed medications for stroke prevention could interact with gender-affirming hormone therapies. Neurologists should collaborate with primary care providers and endocrinologists to screen for and manage cerebrovascular disease risk factors for the primary and secondary prevention of stroke. Limited evidence suggests intersex people may be at higher risk of cerebrovascular disease, particularly those with congenital adrenal hyperplasia (CAH). People diagnosed with CAH have unique risk factors of stroke including treatment with stress-dose corticosteroids or polycythemia due to hyperandrogenism.

Summary

Creating affirming environments and increasing knowledge of health care for SGD communities may lead to improved equitable treatment of SGD patients with stroke by increasing community trust in health providers and incorporating use of best practices in clinical care and research settings. Limited data exist on stroke clinical presentations and how stroke is experienced and treated among SGD people, particularly among those with multiple marginalized identities, those presenting with acute stroke, and those requiring secondary stroke prevention.

Hormones, Stress, and Heart Disease in Transgender Women with HIV in LITE Plus

INTRODUCTION

Cardiovascular disease (CVD) is a leading cause of death among transgender women and people with HIV. Exogenous estrogen and psychosocial stressors are known risk factors for CVD. Yet, few studies have used biomarkers to examine the role of stress in CVD risk among transgender women with HIV (TWHIV). This analysis examined whether stress moderates relationships between gender-affirming hormone therapy (GAHT) duration and CVD risk among TWHIV.

METHODS

This cross-sectional analysis of baseline data from an observational cohort of 108 Black and Latina TWHIV in Boston, New York, and Washington, DC, enrolled December 2020 to June 2022, measured sociodemographics, medical diagnoses, medications, smoking history, and perceived stress via interviewer-administered surveys. Physiological stress was measured with 14 biomarkers to calculate allostatic load indices (ALI). Forty participants provided saliva samples used to calculate cortisol awakening response and cortisol daily decline. The 2018 American College of Cardiology Revised Pooled Cohort Equation estimated 10-year CVD risk. Data were analyzed in 2024.

RESULTS

GAHT duration was positively associated with CVD risk scores in bivariate regression. In multivariable linear regression models (adjusting for age, income, education), only age and ALI remained significantly associated with CVD risk scores (β 1.13, CI: 1.05, 1.21). No stress measure significantly interacted with GAHT duration to affect CVD risk scores. In visual plots, GAHT duration increased CVD risk scores only for TWHIV experiencing the highest ALI.

CONCLUSIONS

Stress plays an important role in CVD in TWHIV. More research is needed on non-GAHT factors, which influence CVD health among transgender women.

Sex hormone-dependent host-microbiome interactions and cardiovascular risk (XCVD): design of a longitudinal multi-omics cohort study

INTRODUCTION

Cardiovascular diseases (CVDs) present differently in women and men, influenced by host-microbiome interactions. The roles of sex hormones in CVD outcomes and gut microbiome in modifying these effects are poorly understood. The XCVD study examines gut microbiome mediation of sex hormone effects on CVD risk markers by observing transgender participants undergoing gender-affirming hormone therapy (GAHT), with findings expected to extrapolate to cisgender populations.

METHODS AND ANALYSES

This observational, longitudinal cohort study includes baseline, 1- and 2-year follow-ups with transgender participants beginning GAHT. It involves comprehensive phenotyping and microbiome genotyping, integrating computational analyses of high-dimensional data. Microbial diversity will be assessed using gut, skin, and oral samples via 16S rRNA and shotgun metagenomic sequencing of gut samples. Blood measurements will include sex hormones, CVD risk markers, cardiometabolic parameters, cytokines, and immune cell counts. Hair samples will be analysed for cortisol. Participants will complete online questionnaires on physical activity, mental health, stress, quality of life, fatigue, sleep, pain, and gender dysphoria, tracking medication use and diet to control for confounders. Statistical analyses will integrate phenomic, lifestyle, and multi-omic data to model health effects, testing gut microbiome mediation of CVD risk as the endocrine environment shifts between that typical for cisgender men to women and vice versa.

ETHICS AND DISSEMINATION

The study adheres to Good Clinical Practice and the Declaration of Helsinki. The protocol was approved by the Charité Ethical Committee (EA1/339/21). Signed informed consent will be obtained. Results will be published in peer-reviewed journals and conferences and shared as accessible summaries for participants, community groups, and the public, with participants able to view their data securely after public and patient involvement review for accessibility.

TRIAL REGISTRATION NUMBER

The XCVD study was registered on ClinicalTrials.gov (NCT05334888) as 'Sex-differential host-microbiome CVD risk - a longitudinal cohort approach (XCVD)" on 4 April 2022. Data set link can be found at https://classic.

Association Between Gender-affirming Hormone Therapy and Measures of Glucose Metabolism: A Longitudinal Study

CONTEXT

The long-term effect of gender-affirming hormone therapy (GAHT) on glucose metabolism is an area of priority in transgender health research.

OBJECTIVES

To evaluate the relation between GAHT and changes in fasting blood glucose (FG) and glycosylated hemoglobin (HbA1c) in transmasculine (TM) and transfeminine (TF) persons relative to the corresponding temporal changes in presumably cisgender persons (ie, without any evidence of gender diversity).

DESIGN

Retrospective cohort study.

SETTING

Three large integrated health systems.

PARTICIPANTS

A total of 2148 TF and 1679 TM persons compared with 28 036 cisgender males and 32 548 cisgender females enrolled in the same health plans.

OUTCOMES/MEASURES

Temporal changes in FG and HbA1c levels examined using linear mixed models with main results expressed as ratios-of-ratios.

RESULTS

The pre- vs post-GAHT ratios-of-ratio (95% CI) estimates adjusted for age, race/ethnicity, study site, and body mass index in the model comparing TF and cisgender males groups were 1.05 (1.01-1.09) for FG and 1.03 (0.99-1.06) for HbA1c. By contrast, the corresponding results in the models contrasting TM and cisgender cohort members were in the 0.99 to 1.00 range. The ratio-of-ratios comparing post-GAHT changes among transgender and cisgender persons were close to the null and without a discernable pattern.

CONCLUSION

Though the within-transgender cohort data suggest an increase in the levels of FG and HbA1c following feminizing GAHT initiation, these changes were no longer evident when compared with the corresponding changes in cisgender referents. Based on these results, clinically important effects of GAHT on routine laboratory markers of glucose metabolism appear unlikely.

Heart Breaking Differences: A Narrative Review of Sex and Gender Disparities in Sports-Related Sudden Cardiac Death

PURPOSE

Sports-related sudden cardiac death (srSCD) represents a rare yet significant occurrence. This review aims to explore the epidemiology, etiology, and prevention of srSCD, with a particular focus on the influence of sex and gender. It seeks to analyze existing literature to elucidate the impact of biological variables, societal factors, and preventive measures in understanding and addressing srSCD among athletes.

METHODS

A narrative review approach was utilized to synthesize relevant literature on srSCD, using a validated PubMed Search tool for sex and gender-related factors. The review focused on primary data investigating sex differences that may contribute to srSCD, as well as pertinent review articles.

FINDINGS

The review highlights the complexity of defining and studying srSCD, with challenges stemming from varied reporting methods and lack of standardized definitions. Disparities in incidence rates between male and female athletes are evident, with males exhibiting a disproportionately higher risk. Biological factors, including cardiac adaptations to exercise and sex hormone influences, contribute to these sex-specific differences in srSCD rates. While screening programs, particularly utilizing electrocardiograms, show promise in identifying at-risk individuals, debates persist regarding their implementation and efficacy. Furthermore, legislative gaps in mandating the availability of automatic external defibrillators (AEDs) in public settings underscore the need for unified advocacy efforts to improve access to life-saving interventions.

IMPLICATIONS

Understanding the multifaceted nature of srSCD, including its biological underpinnings and societal implications, is crucial for developing effective preventive strategies. Sex-specific screening programs tailored to the unique risk profiles of male and female athletes, as well as legislative initiatives promoting AED placement and cardiopulmonary resuscitation training, are essential components of comprehensive srSCD prevention efforts. By addressing disparities and implementing evidence-based interventions, this paper advocates for a holistic approach to mitigate the risk of srSCD and enhance the safety and well-being of athletes across all levels of competition.

Chiropractic Care for a Posterior Tibialis Tendon Tear in a Transgender Male Athlete with Gender-Affirming Hormone Therapy

Objective

The purpose of this case study was to report the management of a patient with posterior tibialis tendon injury concurrent with gender-affirming hormone therapy (GAHT).

Clinical Features

A 31-year-old transgender male presented to a chiropractic clinic with spontaneous, right medial foot pain following running that day. Medical history revealed bilateral congenital pes planus and intramuscular administration of testosterone for 8 years. Physical examination revealed swelling and tenderness around the medial and lateral malleoli and anterior ankle and along the medial longitudinal arch. Plantarflexion and dorsiflexion strength measured 4 out of 5. An 8 out of 10 pain level affected weight-bearing activities and sleep. Lower extremity functional scale measured 81% disability. Multimodal imaging was used in the patient's workup. Diagnostic ultrasound revealed a grade 2 tear of the posterior tibialis tendon adjacent to the medial malleolus along with additional sites of tendinosis. Referral to orthopedist and subsequent magnetic resonance imaging of the right foot and ankle confirmed the diagnosis of grade 2 tear in the posterior tibialis tendon.

Intervention and Outcome

The patient elected chiropractic care following the surgical recommendation. Nonpharmacologic management included neuromuscular re-education using whole body vibration therapy, therapeutic exercise, and ankle mortise joint mobilizations. The patient's clinical status improved, and the lower extremity functional scale measured 27% disability.

Conclusion

Although the patient was 31 years old, GAHT is recognized as a risk factor for tendinosis in older adults. An improved understanding of the correlation between tendinosis and GAHT could optimize patient outcomes and clarify the role of musculoskeletal rehabilitation for treatment.

Clinical and Biochemical Outcomes in Transgender Individuals Undergoing Hormone Therapy: Protocol for a Systematic Review

BACKGROUND

Monitoring of various clinical outcomes and parameters, such as lipid levels, is recommended in transgender individuals undergoing hormone therapies. However, comprehensive data to inform these recommendations is scarce.

OBJECTIVE

This study aims to conduct a systematic review and meta-analysis to synthesize evidence from existing literature on the effect of exogenous hormone therapy on clinical and biochemical outcomes for transgender adolescents and adults.

METHODS

We will search multiple electronic databases and will include prospective and retrospective observational studies with and without a control group. The study population will include transgender individuals undergoing hormone therapy with testosterone or estrogen. Comparisons will include age-matched, cisgender individuals and changes from baseline. Primary outcomes include changes in or the development of abnormal lipid parameters. Secondary outcomes include BMI, weight, height, and blood pressure for age, serum testosterone or estrogen levels, and development of disease including hypertension, diabetes, fatty liver disease, obesity, adverse cardiac events, as well as all-cause mortality. The meta-analysis will pool the studies where applicable, and meta-regressions will be conducted to evaluate effect modifiers. The GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach will be used to evaluate the overall certainty of evidence.

RESULTS

We will summarize the selection of the eligible studies using a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) flowchart. The results will be presented in a table summarizing the evidence. Data collection is ongoing, and the paper is expected to be published in Spring 2025.

CONCLUSIONS

This systematic review will summarize and evaluate the evidence of the clinical and biochemical outcomes associated with hormone therapies for transgender individuals.

A gender perspective on diet, microbiome, and sex hormone interplay in cardiovascular disease

A unique interplay between body and environment embeds and reflects host-microbiome interactions that contribute to sex-differential disease susceptibility, symptomatology, and treatment outcomes. These differences derive from individual biological factors, such as sex hormone action, sex-divergent immune processes, X-linked gene dosage effects, and epigenetics, as well as from their interaction across the lifespan. The gut microbiome is increasingly recognized as a moderator of several body systems that are thus impacted by its function and composition. In humans, biological sex components further interact with gender-specific exposures such as dietary preferences, stressors, and life experiences to form a complex whole, requiring innovative methodologies to disentangle. Here, we summarize current knowledge of the interactions among sex hormones, gut microbiota, immune system, and vascular health and their relevance for sex-differential epidemiology of cardiovascular diseases. We outline clinical implications, identify knowledge gaps, and place emphasis on required future studies to address these gaps. In addition, we provide an overview of the caveats associated with conducting cardiovascular research that require consideration of sex/gender differences. While previous work has inspected several of these components separately, here we call attention to further translational utility of a combined perspective from cardiovascular translational research, gender medicine, and microbiome systems biology.

Exploring Safety in Gender-Affirming Hormonal Treatments: An Observational Study on Adverse Drug Events Using the Food and Drug Administration Adverse Event Reporting System Database

BACKGROUND

People with gender dysphoria are treated with hormone therapy for gender reassignment. The indication of this therapy was initially for the opposite sex, and information on potential adverse drug reaction (ADR) is lacking.

OBJECTIVE

To describe ADR associated with gender transition medication in transgender individuals reported to the US Food and Drug Administration Adverse Event Reporting System (FAERS) database.

METHODS

Data from the FAERS database up to June 2023 were examined, focusing on reports of gender transition medication use in the context of gender dysphoria. The ADRs were categorized using the Medical Dictionary for Regulatory Activities at both Preferred Term and System Organ Class (SOC) levels. Descriptive statistics summarized report counts, medication types, indications, and ADR severity.

RESULTS

For individuals assigned female at birth undergoing gender transition to male (transgender men), 82 reports (230 ADRs) were analyzed, with an average age of 29.5 years. Transgender hormonal therapy was cited in 72% of reports, predominantly from the United States (67.1%). A striking 88% were categorized as serious ADRs, primarily SOC injury, poisoning, and procedural complications (26.5%), followed by psychiatric disorders (14.8%) and nervous system disorders (12.2%). Among those assigned sex male at birth transitioning to female (transgender women) (81 reports, 237 ADRs), mean age was 33.3 years, with 58% indicating use for gender dysphoria. A significant proportion (53.6%) were serious ADRs, primarily SOC: injury, poisoning, and procedural complications (26.6%).

CONCLUSIONS AND RELEVANCE

The FAERS data reveal significant ADRs in transgender individuals using hormone therapy, sometimes unintended for their recipient gender. Population-level studies are crucial to enhance transgender health care. Spontaneous surveillance databases like FAERS illuminate off-label ADRs, urging health care providers to approach hormone therapies with informed caution.

Addressing US Military Transgender Care Inequalities: Clinical Nurse Specialist Bridging Healthcare Gaps

PURPOSE/OBJECTIVES

There are more than 130 000 US veterans and more than 12 500 active-duty service members who identify as transgender. Lack of training in transgender and gender-affirming care among healthcare providers in the military is still reported. The article aims to explore and advocate for the unique role of advanced practice registered nurses, especially clinical nurse specialists, in providing culturally sensitive and evidence-based care to the transgender population within the US military.

DESCRIPTION OF THE PROJECT/PROGRAM

The clinical nurse specialists' pivotal role in policy advocacy and translation of evidence to improve the quality of care and patient outcomes for transgender service members is highlighted. The article also explores the historical journey of transgender care in the US military, addressing discriminatory policies and the implications of the ever-evolving regulations in military transgender healthcare.

OUTCOME

The article aims to create awareness of clinical nurse specialist utilization in US military healthcare services to improve the care of transgender individuals in the military.

CONCLUSION

The uncertain future for transgender service members highlights the ongoing commitment needed to navigate complex military healthcare policies and foster inclusive, evidence-based practices. Therefore, the clinical nurse specialist plays a pivotal role in shaping the future of transgender healthcare within the US military.

Impact of Gender-Affirming Hormonal Therapy on Cardiovascular Risk Factors in Transgender Health: An Updated Meta-Analysis

Background

Gender-affirming hormone therapy (GAHT) is common among transgender individuals, but its impact on lipid profile and cardiovascular health is not well studied.

Objectives

The authors performed a systematic review and meta-analysis of existing literature to assess the impact of GAHT on lipid profiles and metabolic cardiovascular risk factors in transgender individuals.

Methods

Online databases including MEDLINE/PubMed, Embase, and Cochrane Central registry were searched to find studies on lipid profile changes in women who are transgender, also referred to as transfeminine (TF), and men who are transgender, also referred to as transmasculine (TM) before and after GAHT. Baseline comorbidities were analyzed using descriptive statistics, and R-statistical software was used to analyze the mean difference in lipid profile change between the two cohorts (pre- and post-GAHT therapy) including transgender patients.

Results

Overall, 1,241 TM and 992 TF patients were included from 12 observational studies and 12 randomized controlled trials. The mean age among TM and TF was 28 years and 30 years, respectively. The mean follow-up duration (including pre- and post-GAHT therapy) was 28 months in TM patients and 39 months in TF patients. When compared to baseline measures, TM patients had a significant increase in low-density lipoprotein, triglyceride levels, and total cholesterol while high-density lipoprotein levels decreased. In TF patients, there was a significant increase in triglyceride levels.

Conclusions

GAHT affects lipid profiles in transgender patients; however, additional studies are needed to determine how these changes impact clinical outcomes.

Safe and supportive prescribing in transgender and non-binary patients with cancer

Global prevalence rates for transgender individuals vary with estimates ranging from 0.3% to 1%, translating to a potential global population of 24.3 million to 81 million. It is estimated that one in two people will develop cancer in their lifetime. Gender-affirming hormone therapy (GAHT) is a common medical intervention for transgender and non-binary individuals. GAHT requires careful consideration for concurrent medical care due to potential drug interactions and physiological changes. A multi-disciplinary team with expertise in transgender health, oncology and pharmacy met to develop a document summarizing current knowledge on the topic for practical use. The team included trans and non-binary authors who shaped the document's language and focus. The document gives a status update on the current understanding of GAHT and how this may intersect with the safe prescribing of systemic anti-cancer therapies (SACT). The document underwent multiple review stages including internal review, review by the British Oncology Pharmacy Association (BOPA) EDI Subcommittee and, finally, BOPA Executive Committee review and final approval. Key recommendations of this document include the use of inclusive and effective communication, vigilant monitoring of kidney function and cardiovascular health, and considerations for hormone receptor-positive cancers. The document also recognizes the multidisciplinary nature of transgender healthcare and where this relates to social prescribing.

Lesbian, Gay, Bisexual, Transgender, Queer, and Other Sexual and Gender Minority Health Disparities: A Position Paper From the American College of Physicians

Lesbian, gay, bisexual, transgender, queer, or other sexual and gender minorities (LGBTQ+) populations in the United States continue to experience disparities in health and health care. Discrimination in both health care and society at large negatively affects LGBTQ+ health. Although progress has been made in addressing health disparities and reducing social inequality for these populations, new challenges have emerged. There is a pressing need for physicians and other health professionals to take a stance against discriminatory policies as renewed federal and state public policy efforts increasingly impose medically unnecessary restrictions on the provision of gender-affirming care. In this position paper, the American College of Physicians (ACP) reaffirms and updates much of its long-standing policy on LGBTQ+ health to strongly support access to evidence-based, clinically indicated gender-affirming care and oppose political efforts to interfere in the patient-physician relationship. Furthermore, ACP opposes institutional and legal restrictions on undergraduate, graduate, and continuing medical education and training on gender-affirming care and LGBTQ+ health issues. This paper also offers policy recommendations to protect the right of all people to participate in public life free from discrimination on the basis of their gender identity or sexual orientation and encourages the deployment of inclusive, nondiscriminatory, and evidence-based blood donation policies for members of LGBTQ+ communities. Underlying these beliefs is a reaffirmed commitment to promoting equitable access to quality care for all people regardless of their sexual orientation and gender identity.

MicroRNA in cardiometabolic health and disease: The perspectives of sex, gender and personalised medicine

BACKGROUND

Personalized medicine represents a novel and integrative approach that focuses on an individual's genetics and epigenetics, precision medicine, lifestyle and exposures as key players of health status and disease phenotypes.

METHODS

In this narrative review, we aim to carefully discuss the current knowledge on gender disparities in cardiometabolic diseases, and we consider the sex- specific expression of miRNAs and their role as promising tool in precision medicine.

RESULTS

Personalised medicine overcomes the restricted care of patient based on a binomial sex approach, by enriching itself with a holistic and dynamic gender integration. Recognized as a major worldwide health emergency, cardiometabolic disorders continue to rise, impacting on health systems and requiring more effective and targeted strategies. Several sex and gender drivers might affect the onset and progression of cardiometabolic disorders in males and females at multiple levels. In this respect, distinct contribution of genetic and epigenetic mechanisms, molecular and physiological pathways, sex hormones, visceral fat and subcutaneous fat and lifestyle lead to differences in disease burden and outcomes in males and females.

CONCLUSIONS

Sex and gender play a pivotal role in precision medicine because the influence the physiology of each individual and the way they interact with environment from intrauterine life.

Clinicians in the Veterans Health Administration initiate gender-affirming hormone therapy in concordance with clinical guideline recommendations

Background

Gender-affirming hormone therapy (GAHT) is a common medical intervention sought by transgender and gender diverse (TGD) individuals. Initiating GAHT in accordance with clinical guideline recommendations ensures delivery of high-quality care. However, no prior studies have examined how current GAHT initiation compares to recommended GAHT initiation.

Objective

This study assessed guideline concordance around feminizing and masculinizing GAHT initiation in the Veterans Health Administration (VHA).

Methods

The sample included 4,676 veterans with a gender identity disorder diagnosis who initiated feminizing (n=3,547) and masculinizing (n=1,129) GAHT between 2007 and 2018 in VHA. Demographics and health conditions on veterans receiving feminizing and masculinizing GAHT were assessed. Proportion of guideline concordant veterans on six VHA guidelines on feminizing and masculinizing GAHT initiation were determined.

Results

Compared to veterans receiving masculinizing GAHT, a higher proportion of veterans receiving feminizing GAHT were older (≥60 years: 23.7% vs. 6.3%), White non-Hispanic (83.5% vs. 57.6%), and had a higher number of comorbidities (≥7: 14.0% vs. 10.6%). A higher proportion of veterans receiving masculinizing GAHT were Black non-Hispanic (21.5% vs. 3.5%), had posttraumatic stress disorder (43.0% vs. 33.9%) and positive military sexual trauma (33.5% vs.16.8%; all p-values<0.001) than veterans receiving feminizing GAHT. Among veterans who started feminizing GAHT with estrogen, 97.0% were guideline concordant due to no documentation of contraindication, including venous thromboembolism, breast cancer, stroke, or myocardial infarction. Among veterans who started spironolactone as part of feminizing GAHT, 98.1% were guideline concordant as they had no documentation of contraindication, including hyperkalemia or acute renal failure. Among veterans starting masculinizing GAHT, 90.1% were guideline concordant due to no documentation of contraindications, such as breast or prostate cancer. Hematocrit had been measured in 91.8% of veterans before initiating masculinizing GAHT, with 96.5% not having an elevated hematocrit (>50%) prior to starting masculinizing GAHT. Among veterans initiating feminizing and masculinizing GAHT, 91.2% had documentation of a gender identity disorder diagnosis prior to GAHT initiation.

Conclusion

We observed high concordance between current GAHT initiation practices in VHA and guidelines, particularly for feminizing GAHT. Findings suggest that VHA clinicians are initiating feminizing GAHT in concordance with clinical guidelines. Future work should assess guideline concordance on monitoring and management of GAHT in VHA.

Sex and gender differences in risk scores for dementia and Alzheimer's disease among cisgender, transgender, and non-binary adults

INTRODUCTION

Few studies have explored dementia risk according to sex and gender including for transgender and non-binary adults. This study evaluated dementia risk factors and risk scores among cisgender, transgender, and non-binary adults.

METHODS

Observational data were drawn from the 2019 Behavioral Risk Factor Surveillance System. A matched-cohort approach was used to develop sex (male, female) and gender identity cohorts (cisgender men, cisgender women, transgender men, transgender women, and non-binary adults) for comparison. Dementia risk scores were calculated using established mid-life and late-life risk score algorithms.

RESULTS

Males had higher overall mid-life dementia risk, and lower late-life Alzheimer's disease risk compared to females. Transgender men, transgender women, and non-binary adults had higher overall late-life risk compared to both cisgender men and women.

DISCUSSION

Future research is needed to build the evidence base for specific risk factors that may be contributing to higher overall risk among understudied and underserved gender groups.

HIGHLIGHTS

Using data from the 2019 Behavioral Risk Factor Surveillance System, this matched-cohort study found that those assigned female at birth had lower overall mid-life dementia risk and higher overall late-life Alzheimer's disease (AD) risk compared to those assigned male at birth. Transgender men, transgender women, and non-binary adults all showed higher overall late-life AD risk compared to cisgender men and cisgender women. Between-group differences were found in the incidence of specific risk and protective factors for dementia and AD.

Considerations for hormonal therapy in migraine patients: a critical review of current practice

INTRODUCTION

Migraine, a neurovascular headache disorder, is a leading cause of disability worldwide. Within the multifaceted pathophysiology of migraine, hormonal fluctuations play an evident triggering and exacerbating role, pointing toward the need for identification and proper usage of both existing and new hormonal targets in migraine treatment.

AREAS COVERED

With a threefold higher incidence of migraine in women than in men, the authors delve into sex hormone-related events in migraine patients. A comprehensive overview is given of existing hormonal therapies, including oral contraceptives, intrauterine devices, transdermal and subcutaneous estradiol patches, gnRH-agonists, oral testosterone, and 5α reductase inhibitors. The authors discuss their effectiveness and risks, noting their suitability for different patient profiles. Next, novel evolving hormonal treatments, such as oxytocin and prolactin, are explored. Lastly, the authors cover hormonal conditions associated with migraine, such as polycystic ovary syndrome, endometriosis, and transgender persons receiving gender affirming hormone therapy, aiming to provide more personalized and effective solutions for migraine management.

EXPERT OPINION

Rigorous research into both existing and new hormonal targets, as well as the underlying pathophysiology, is needed to support a tailored approach in migraine treatment, in an ongoing effort to alleviate the impact of migraine on individuals and society.

Outcomes of Orchiectomy for Gender-affirming Surgery: A National Surgical Quality Improvement Program Study

OBJECTIVE

To identify perioperative outcomes of transgender orchiectomy (TGO) and to broadly compare outcomes of TGO to cisgender orchiectomy (CGO) for nononcologic indications.

METHODS

Using the National Surgical Quality Improvement Program (NSQIP) database from 2010 to 2020, a retrospective study was performed on patients with ICD-9/10 codes for gender dysphoria, testicular torsion, and testicular pain who underwent simple orchiectomy. Demographics and surgical outcomes were summarized. Welch two-sample t test and chi-square test were used for group analysis. A trend analysis was performed for temporal trends of these surgeries.

RESULTS

246 patients underwent TGO and 997 patients underwent CGO (607 testicular torsion, 390 testicular pain). Overall complication rates between TGO and CGO did not differ for testicular torsion (3.7% vs 4.4%, P = .6) or testicular pain (3.7% vs 5.9%, P = .2). No differences in patient characteristics were seen within the TGO group when comparing those who experienced complications to those who didn't. From 2015 to 2020, TGO cases significantly increased by, on average, 9.5 cases per year (95% CI: 6.3-12.7, P = .001), while CGO had showed no significant temporal change.

CONCLUSION

Standalone TGO can be performed safely in an outpatient setting with an acceptable complication profile in medically diverse patients.

The aging brain: risk factors and interventions for long term brain health in women

PURPOSE OF REVIEW

Poor cognitive aging and dementia pose a significant public health burden, and women face unique risks compared to men. Recent research highlights the role of genetics, menopause, chronic disease, and lifestyle in risk and resilience in women's cognitive aging. This work suggests avenues for clinical action at midlife that may change the course of brain health in aging.

RECENT FINDINGS

Studies indicate women's risk for poor cognitive aging relates in part to hormone changes at menopause, a time when memory, brain structure and function, and Alzheimer's pathology may be observed in women and not men. Medical and lifestyle risks including diabetes, hypertension, and low physical activity also contribute to women's unique risks. At the same time, literature on resilience suggests women may benefit from lifestyle and chronic disease intervention, possibly more than men. Current studies emphasize the importance of interacting genetic and lifestyle risks, and effects of social determinants of health.

SUMMARY

Women have greater risk than men for poor cognitive aging; however, by treating the whole person, including genetics, lifestyle, and social environment, clinicians have an opportunity to support healthy cognitive aging in women and reduce the future public health burden of dementia.

[Contraception for transgender men: A case report and review]

All methods of contraception used by a cisgender woman can theoretically be used by a transgender man. In practice, some contraceptives can aggravate gender dysphoria and should be discarded. On the other hand, contraceptives which make it possible to consolidate amenorrhea or to accentuate the virilization induced by taking testosterone will be better tolerated.

Particularities of physical training and control of risk factors in the transgender and gender-diverse population

The transgender and gender-diverse (TGD) population holds significant relevance concerning exercise and sports practices. Specific challenges are highlighted, such as physical inactivity driven by internal and external reasons, including discrimination in sports environments. Psychological aspects and hormonal therapy effects create implications for hindering participation in sports competitions. Disparities in cardiovascular risk factors are also mentioned, emphasizing the need for inclusive sports policies based on scientific evidence. The article underscores the importance of addressing social, psychological, and medical aspects to promote the physical and mental health of the TGD population, particularly in the professional sports area.

Zinc in Prostate Health and Disease: A Mini Review

Introduction-With the high global prevalence of prostate cancer and associated mortalities, it is important to enhance current clinical practices for better prostate cancer outcomes. The current review is towards understanding the value of Zn towards this mission. Method-General information on Zn in biology and multiple aspects of Zn involvement in prostate health and disease were referred to in PubMed. Results-The most influential feature of Zn towards prostate health is its ability to retain sufficient citrate levels for a healthy prostate. Zn deficiencies were recorded in serum, hair, and prostate tissue of men with prostate cancer compared to non-cancer controls. Zn gut absorption, albumin binding, and storage compete with various factors. There are multiple associations of Zn cellular influx and efflux transporters, Zn finger proteins, matrix metalloproteinases, and Zn signaling with prostate cancer outcomes. Such Zn marker variations associated with prostate cancer recorded from biological matrices may improve algorithms for prostate cancer screening, prognosis, and management when coupled with standard clinical practices. Discussion-The influence of Zn in prostatic health and disease is multidimensional, therefore more personalized Zn requirements may be beneficial. Several opportunities exist to utilize and improve understanding of Zn associations with prostate health and disease.

Cardiovascular outcomes in transgender individuals in Sweden after initiation of gender-affirming hormone therapy

AIMS

We compared the incidence of cardiovascular disease (CVD) in transgender participants with a diagnosis of gender dysphoria (GD) with and without gender-affirming hormone therapy (GAHT) to the incidence observed in the general population.

METHODS AND RESULTS

The population-based cohort included all individuals >10 years in Sweden linked to Swedish nationwide healthcare Registers (2006-16). Two comparator groups without GD/GAHT were matched (1:10) on age, county of residence, and on male and female birth-assigned sex, respectively. Cox proportional models provided hazard ratios (HRs) and 95% confidence intervals (CI) for CVD outcomes. Among 1779 transgender individuals [48% birth-assigned males (AMAB), 52% birth-assigned females (AFAB)], 18 developed CVD, most of which were conduction disorders. The incidence of CVD for AFAB individuals with GD was 3.7 per 1000 person-years (95% CI: 1.4-10.0). Assigned male at birth individuals with GD had an incidence of CVD event of 7.1 per 1000 person-years (95% CI: 4.2-12.0). The risk of CVD event was 2.4 times higher in AMAB individuals (HR: 2.4, 95% CI: 1.3-4.2) compared with cisgender women, and 1.7 higher compared with cisgender men (HR: 1.7, 95% CI: 1.0-2.9). Analysis limited to transgender individuals without GAHT yielded similar results to those with GAHT treatment.

CONCLUSION

The incidence of CVD among GD/GAHT individuals was low, although increased compared with matched individuals without GD and similar to the incidence among GD/no GAHT individuals, thus not lending support for a causal relationship between treatment and CVD outcomes. Larger studies with longer follow-up are needed to verify these findings, as well as possible effect modification by comorbidity.
