Gender Affirmation Surgery (GAS) is a super specialized subset within the field of plastic and reconstructive surgery (PRS) that is ever evolving and of increasing interest to the PRS community. It is a multifaceted process which, in addition to surgical therapy, involves mental health therapy and hormonal therapy. One rapidly emerging interest within GAS is the role that gender affirming hormone therapy (GAHT) plays in enhancing surgical outcomes. GAHT has been used adjunctively with GAS as a comprehensive therapy to ameliorate gender dysphoria. This literature review will examine the positive effects of GAHT on the surgical outcomes on GAS, as well as other important considerations prior to surgery. As such, the primary objective of this literature review is to evaluate and assess the current evidence concerning the efficacy and safety of GAHT, as it relates to Gender Affirmation Surgery procedures.

BACKGROUND: Mathematical models of HIV have been uniquely important in directing and evaluating HIV policy. Transgender and nonbinary people are disproportionately impacted by HIV; however, few mathematical models of HIV transmission have been published that are inclusive of transgender and nonbinary populations. This commentary discusses current structural challenges to developing robust and accurate trans-inclusive models and identifies opportunities for future research and policy, with a focus on examples from the United States.
CONCLUSIONS: As of April 2024, only seven published mathematical models of HIV transmission include transgender people. Existing models have several notable limitations and biases that limit their utility for informing public health intervention. Notably, no models include transgender men or nonbinary individuals, despite these populations being disproportionately impacted by HIV relative to cisgender populations. In addition, existing mathematical models of HIV transmission do not accurately represent the sexual network of transgender people. Data availability and quality remain a significant barrier to the development of accurate trans-inclusive mathematical models of HIV. Using a community-engaged approach, we developed a modelling framework that addresses the limitations of existing model and to highlight how data availability and quality limit the utility of mathematical models for transgender populations.
CONCLUSIONS: Modelling is an important tool for HIV prevention planning and a key step towards informing public health interventions, programming and policies for transgender populations. Our modelling framework underscores the importance of accurate trans-inclusive data collection methodologies, since the relevance of these analyses for informing public health decision-making is strongly dependent on the validity of the model parameterization and calibration targets. Adopting gender-inclusive and gender-specific approaches starting from the development and data collection stages of research can provide insights into how interventions, programming and policies can distinguish unique health needs across all gender groups. Moreover, in light of the data structure limitations, designing longitudinal surveillance data systems and probability samples will be critical to fill key research gaps, highlight progress and provide additional rigour to the current evidence. Investments and initiatives like Ending the HIV Epidemic in the United States can be further expanded and are highly needed to prioritize and value transgender populations across funding structures, goals and outcome measures.

The phenomenon of dielectric switching has garnered considerable attention due to its potential applications in electronic and photonic devices. Typically, hybrid organic-inorganic perovskites, HOIPs, exhibit a binary (low-high) dielectric state transition, which, while useful, represents only the tip of the iceberg in terms of functional relevance. One way to boost the versatility of applications is the discovery of materials capable of nonbinary switching schemes, such as three-state dielectric switching. The ideal candidate for that task would exhibit a trio of attributes: two reversible, first-order phase transitions across three distinct crystal phases, minimal thermal hysteresis, and pronounced, step-like variations in dielectric permittivity, with a substantial change in its real part. Here, we demonstrate a one-dimensional lead halide perovskite with the formula (CH3)2C(H)NH3)PbI3, abbreviated as ISOPrPbI3, that fulfills these criteria and demonstrates three-state dielectric switching within a narrow temperature range of ca. 45 K. Studies on ISOPrPbI3 also revealed the polar nature of the low-temperature phase III below 266 K through pyrocurrent experiments, and the noncentrosymmetric character of the intermediate phase II and low-temperature phase III is confirmed via second harmonic generation measurements. Additionally, luminescence studies of ISOPrPbI3 have demonstrated combined broadband and narrow emission properties. The introduction of ISOPrPbI3 as a three-state dielectric switch not only addresses the limitations posed by the wide thermal gap between dielectric states in previous materials but also opens new avenues for the development of nonbinary dielectric switchable materials.

Prior research suggests that prejudice and structural disadvantage (e.g., cissexism, racism, sexism) put transgender and nonbinary (TNB) young adults at risk for adverse romantic relationship experiences, yet supportive romantic relationships may help TNB young adults cope with these stressors and promote their psychological wellbeing. Accordingly, there is a need to better understand how TNB young adults navigate romantic relationships in the context of prejudice and structural disadvantage. To address this topic, we analyzed in-depth interviews with TNB young adults (18-30 years; N=30) using template-style thematic analysis, guided by intersectionality as an analytical framework. Our analysis resulted in three themes. Theme 1 describes how prejudice and structural disadvantage constrained the strategies that TNB young adults used to pursue fulfilling romantic relationships (e.g., leaving adverse relationships). Theme 2 addresses the tradeoffs that some participants faced in their romantic relationships, including tradeoffs between psychological needs related to their social identities (e.g., gender identity affirmation) and general psychological needs (e.g., intimacy). Theme 3 highlights individual and contextual factors (e.g., lessons from prior romantic relationships) that helped participants build fulfilling romantic relationship. These themes form the basis for the Identity Needs in Relationships Framework, a new conceptual framework addressing how TNB young adults navigate romantic relationships in the context of prejudice and structural disadvantage. The framework offers an explanation for why some TNB young adults maintain romantic relationships that seem to undermine their wellbeing, and it draws attention to strategies and resources that may help TNB young adults form fulfilling romantic relationships despite the prejudice and structural disadvantage they face.

Objectives: The study investigates how trans masculine and nonbinary individuals describe the use of their bodies during sexual activities. Methods: Three hundred and sixty-one trans masculine and nonbinary individuals were asked to describe their use of body during sex through an online survey. Data were analyzed through thematic analysis. Results: Eleven subthemes emerged that were organized in 4 overarching themes: Relational Factors; Behavioral Factors; Sexual Roles; and Transgender Related Factors. Some differences emerged between trans masculine and nonbinary participants. Conclusions: Although some of our participants described a lack of sexual activity, our participants overall described a wide range of activities.

UNASSIGNED: The nonbinary and genderqueer (NBGQ) youth population is growing, yet scant research focuses on this distinct group. We aim to gain a deeper understanding of desired gender-affirming care and interventions pursued by NBGQ youth.
UNASSIGNED: A retrospective chart review of NBGQ patients seen at the University of California, San Francisco Child and Adolescent Gender Center from January 1, 2009, to December 31, 2020, was performed. Demographic information, desired gender-affirming care, and gender-affirming interventions pursued at initial and most recent visits were collected.
UNASSIGNED: Initial visit charts of 116 NBGQ youth who attended more than one clinic visit were reviewed. In total, 48 unique genders were documented; gender evolved over time for some youth, as did desired gender-affirming care. At the most recent visit, 15 youth (12.9%) had a binary gender, and 101 youth (87.1%) had an NBGQ gender. At the initial visit, 56 youth (48.3%) were interested in gender-affirming hormone therapy, compared with 75 youth (65.6%) at the most recent visit. In addition, 21 (18.1%) and 49 (42.2%) youth were interested in surgery at the initial and most recent visits, respectively. In general, interest in interventions was higher than pursuit of interventions.
UNASSIGNED: There is vast diversity of gender and differences in desired gender-affirming care within the NBGQ youth population. Desires for gender-affirming care within the cohort changed over time, and not all those who expressed a desire for an intervention received it. The reasons are likely multifactorial, highlighting the need for expectation-free and patient-specific affirming care and research on the NBGQ youth population, while also considering barriers to care.

BACKGROUND: Despite the increasing interest in transgender health research, to date little is known about the size of the transgender and gender diverse (TGD) population.
METHODS: A web-based questionnaire survey was developed, including a collection of socio-demographic characteristics and disseminated online through social media. Gender incongruence was evaluated by using a 2-item approach assessing gender recorded at birth and gender identity. The primary objective of the present population-based study was to estimate the proportion of TGD people across ages among a large sample of people who answered a web-based survey. The secondary endpoints were to identify gender-affirming needs and possible barriers to healthcare access.
RESULTS: A total of 19,572 individuals participated in the survey, of whom 7.7% reported a gender identity different from the sex recorded at birth. A significantly higher proportion of TGD people was observed in the youngest group of participants compared with older ones. Among TGD people who participated in the study, 58.4% were nonbinary, and 49.1% experienced discrimination in accessing health care services. Nonbinary TGD participants reported both the need for legal name and gender change, along with hormonal and surgical interventions less frequently compared to binary persons.
CONCLUSIONS: Being TGD is not a marginal condition In Italy. A large proportion of TGD persons may not need medical and surgical treatments. TGD people often experience barriers to healthcare access relating to gender identity.

UNASSIGNED: Gender-affirming hormones (hormones)-the use of sex hormones to induce desired secondary sex characteristics in transgender and nonbinary (TGNB) individuals-are vital health care for many TGNB people. Some hormone providers require a letter from a mental health provider before hormone initiation. We explore the perspectives of TGNB individuals regarding the impact of the letter requirement on their experience of care.
UNASSIGNED: We conducted semistructured interviews with 21 TGNB individuals who have sought or are receiving hormones. We purposively sampled respondents who were (n=12) and were not (n=8) required to provide a letter. An Advisory Board of transgender individuals guided the methodology. Interviews were transcribed verbatim and coded both inductively and deductively.
UNASSIGNED: We identified three themes related to the letter requirement: (1) Mental health: While participants appreciated the importance of therapy, the letter requirement did not serve this purpose; (2) Trans identity: The process of obtaining a letter created doubt in participants\' own transness, along with a resistance to the pathologization and conflation of mental illness with transness; and (3) Care relationships: The letter requirement negatively impacted the patient-provider relationship. Participants felt the need to self-censor or to perform a version of transness they thought the provider expected; this process decreased their trust in care professionals.
UNASSIGNED: A letter requirement did not improve mental health and had several negative consequences. Removal of this requirement will improve access to hormones and may paradoxically improve mental health.

UNASSIGNED: Little is known about the prevalence and risks associated with transgender and gender diverse (TGD) persons\' misuse of prescription pain relievers (PPRs). This study explores the relationship between PPR misuse and various sociodemographic identities and experiences of discrimination in health care among TGD adults.
UNASSIGNED: TGD participants (n=595) were recruited in 2018 to participate in a cross-sectional statewide trans health survey through convenience sampling. Chi-square tests of independence and logistic regressions were conducted to explore associations between sociodemographics and experiences of discrimination among persons who had ever misused PPRs, or who had misused PPRs in the past year.
UNASSIGNED: Sociodemographics such as gender identity (odds ratio [OR]=0.44, p=0.01), race/ethnicity (OR=0.14, p<0.001), and sexual orientation influence TGD individuals likeliness of misusing PPRs (OR=0.40, p<0.001). Notably, those who were ever diagnosed with anxiety had a higher likeliness of having lifetime PPR misuse compared with those who were never diagnosed (OR=2.05, p=0.05), and those reporting past-year discrimination within the mental health care setting because of their gender identity were more than twice as likely to report past-year misuse than those who reported not experiencing it (OR=2.43, p=0.004).
UNASSIGNED: Certain subpopulations of TGD individuals may be at elevated risk of PPR misuse. It is imperative to acknowledge the impact of multimarginalized identities as well as differences across various identities and experiences within the TGD community while working to address non-PPR misuse.

UNASSIGNED: Chronic gender-affirming hormone therapy (GAHT) with sublingual estradiol (SLE) has not been studied. We aimed to compare GAHT with SLE only, to combined oral (CO) estradiol and cyproterone acetate, in treatment-naive trans women.
UNASSIGNED: Twenty-two trans women enrolled into either the CO arm or the SLE-only arm (0.5 mg four times daily) in this 6-month prospective study. Anthropometric and laboratory variables were collected at baseline and 3 and 6 months. At the study beginning and end, body composition was measured by dual-energy X-ray absorptiometry and bioelectrical impedance, and gender dysphoria, sexual desire, and function were assessed by validated questionnaires.
UNASSIGNED: Subjects in the SLE were older, 26.3±5.8 years versus 20.1±2.3 years, p=0.006. All anthropometric, body composition, and laboratory variables were identical at baseline. Although dysphoria appeared greater, and sexual function lower at baseline in the CO group, this canceled out after age adjustment. Both treatments induced similar biochemical and hormonal changes. Creatinine, hemoglobin and cholesterol decreased significantly, while testosterone was suppressed to the same level in both groups: 3.22 [1.47-5.0] nmol/L in the SLE group and 2.41 [0.55-8.5] nmol/L in the CO, p=0.65. Significant changes in body composition toward a more feminine body were noted in both groups. Dysphoria did not significantly improve in either group, while sexual desire and function decreased at six months in both, p<0.001.
UNASSIGNED: Both treatments achieved similar clinical changes. At this stage, SLE, which repeatedly induces alarming excursions of serum estradiol throughout the day, appears to offer no advantage over the CO approach.
