A speech therapy for transgender women: an updated systematic review and meta-analysis.

BACKGROUND: We systematically reviewed the literature and performed a meta-analysis on the effects of speech therapy and phonosurgery, for transgender women, in relation to the fundamental frequency gain of the voice, regarding the type of vocal sample collected, and we compared the effectiveness of the treatments. In addition, the study design, year, country, types of techniques used, total therapy time, and vocal assessment protocols were analyzed. METHODS: We searched the PubMed, Lilacs, and SciELO databases for observational studies and clinical trials, published in English, Portuguese, or Spanish, between January 2010 and January 2023. The selection of studies was carried out according to Prisma 2020. The quality of selected studies was assessed using the Newcastle-Ottawa scale. RESULTS: Of 493 studies, 31 were deemed potentially eligible and retrieved for full-text review and 16 were included in the systematic review and meta-analysis. Six studies performed speech therapy and ten studies phonosurgery. The speech therapy time did not influence the post-treatment gain in voice fundamental frequency (p = 0.6254). The type of sample collected significantly influenced the post-treatment voice frequency gain (p < 0.01). When the vocal sample was collected through vowel (p < 0.01) and reading (p < 0.01), the gain was significantly more heterogeneous between the different types of treatment. Phonosurgery is significantly more effective in terms of fundamental frequency gain compared to speech therapy alone, regardless of the type of sample collected (p < 0.01). The average gain of fundamental frequency after speech therapy, in the /a/ vowel sample, was 27 Hz, 39.05 Hz in reading, and 25.42 Hz in spontaneous speech. In phonosurgery, there was a gain of 71.68 Hz for the vowel /a/, 41.07 Hz in reading, and 39.09 Hz in spontaneous speech. The study with the highest gain (110 Hz) collected vowels, and the study with the lowest gain (15 Hz), spontaneous speech. The major of the included studies received a score between 4 and 8 on the Newcastle-Ottawa Scale. CONCLUSION: The type of vocal sample collected influences the gain result of the fundamental frequency after treatment. Speech therapy and phonosurgery increased the fundamental frequency and improved female voice perception and vocal satisfaction. However, phonosurgery yielded a greater fundamental frequency gain in the different samples collected. The study protocol was registered at Prospero (CRD42017078446).

Estradiol Replacement as a Potential Enhancer of Working Memory and Neuroplasticity in Hypogonadal Trans Women.

INTRODUCTION: The cognitive effects of cross-sex hormone therapy (CSHT) are not well understood. In cisgender individuals, sex hormone therapy can impact neurotransmitter levels and structural anatomy. Similarly, in gender-diverse persons, CSHT has been associated with neural adaptations, such as growth in brain structures resembling those observed in cisgender individuals of the same sex. Hormone-related changes in learning and memory, as seen in menopause, are associated with physiological hypogonadism or a decline in hormones, such as estradiol. The present study examined the effect of estradiol administration in humans on glutamate concentration in brain regions involved in semantic and working memory (i.e., the dorsolateral prefrontal cortex [DLPFC], the posterior hippocampus, and the pregenual anterior cingulate cortex) and its relationship with memory. METHODS: Eighteen trans women (male biological sex assigned at birth) ceased CSHT for 30 days for a washout phase (t1) upon study enrollment to reach a hypogonadal state. Working and semantic memory, cognition, hormonal assays, and brain imaging were assessed. Participants resumed CSHT for 60 days for a replacement phase (t2), after which the same evaluations from t1 were repeated. RESULTS: Estradiol increased among trans women after 60 days of resumed CSHT with significant improvements in semantic memory compared to the hypogonadal phase. Working memory recall was significantly and positively correlated to glutamate in the DLPFC during the reinstatement phase, although the relationship was not moderated by levels of estradiol. DISCUSSION: These results may have clinical implications for the therapeutic effects of estradiol replacement, serving as a protective factor against cognitive decline and impairment for trans women post-gonadectomy.

Sexual Function and Quality of Life in Brazilian Transgender Women Following Gender-Affirming Surgery: A Cross-Sectional Study.

This cross-sectional and descriptive study aimed to evaluate the sexual function, urinary function, and quality of life of 26 Brazilian trans women who have undergone gender-affirming surgery (GAS) using the gold standard technique (penile inversion vaginoplasty) in the Gender Identity Transdisciplinary Program at Hospital de Clínicas de Porto Alegre, Brazil, between March 2016 and July 2017. The Female Sexual Function Index, the SF-36 Health Survey, and the International Consultation on Incontinence Questionnaire-Short Form were used. Regarding their surgical results, 84.6% of the women said they were satisfied, 73.1% were sexually functional, and 15.4% reported urinary incontinence not associated with surgery. Participants also reported a good quality of life, despite low scores of pain and physical vitality. Transgender women in our sample reported a good quality of life and sexual function after GAS. Further studies are required to improve the psychosexual wellbeing of this specific population.

A systematic review of the neural correlates of sexual minority stress: towards an intersectional minority mosaic framework with implications for a future research agenda.

BACKGROUND: Systemic oppression, particularly towards sexual minorities, continues to be deeply rooted in the bedrock of many societies globally. Experiences with minority stressors (e.g. discrimination, hate-crimes, internalized homonegativity, rejection sensitivity, and microaggressions or everyday indignities) have been consistently linked to adverse mental health outcomes. Elucidating the neural adaptations associated with minority stress exposure will be critical for furthering our understanding of how sexual minorities become disproportionately affected by mental health burdens.Following PRISMA-guidelines, we systematically reviewed published neuroimaging studies that compared neural dynamics among sexual minority and heterosexual populations, aggregating information pertaining to any measurement of minority stress and relevant clinical phenomena. RESULTS: Only 1 of 13 studies eligible for inclusion examined minority stress directly, where all other studies focused on investigating the neurobiological basis of sexual orientation. In our narrative synthesis, we highlight important themes that suggest minority stress exposure may be associated with decreased activation and functional connectivity within the default-mode network (related to the sense-of-self and social cognition), and summarize preliminary evidence related to aberrant neural dynamics within the salience network (involved in threat detection and fear processing) and the central executive network (involved in executive functioning and emotion regulation). Importantly, this parallels neural adaptations commonly observed among individuals with posttraumatic stress disorder (PTSD) in the aftermath of trauma and supports the inclusion of insidious forms of trauma related to minority stress within models of PTSD. CONCLUSIONS: Taken together, minority stress may have several shared neuropsychological pathways with PTSD and stress-related disorders. Here, we outline a detailed research agenda that provides an overview of literature linking sexual minority stress to PTSD and insidious trauma, moral affect (including shame and guilt), and mental health risk/resiliency, in addition to racial, ethnic, and gender related minority stress. Finally, we propose a novel minority mosaic framework designed to inform future directions of minority stress neuroimaging research from an intersectional lens.

Antecedentes: La opresión sistémica, en particular hacia las minorías sexuales, sigue estando profundamente arraigada en los cimientos de muchas sociedades a nivel mundial. Las experiencias con los factores de estrés de las minorías (por ejemplo, la discriminación, los delitos de odio, la homonegatividad interiorizada, la sensibilidad al rechazo y las microagresiones o humillaciones cotidianas) se han relacionado sistemáticamente con resultados adversos para la salud mental. La elucidación de las adaptaciones neuronales asociadas con la exposición al estrés de las minorías será fundamental para avanzar en nuestra comprensión de cómo las minorías sexuales se ven afectadas de manera desproporcionada por las cargas de salud mental.Métodos: Siguiendo las directrices PRISMA, revisamos sistemáticamente los estudios de neuroimagen publicados que comparaban la dinámica neural entre las poblaciones de minorías sexuales y heterosexuales, agregando la información relativa a cualquier medición del estrés de minorías y los fenómenos clínicos relevantes.Resultados: Sólo 1 de los 13 estudios elegibles para su inclusión examinó directamente el estrés de las minorías, mientras que todos los demás estudios se centraron en investigar las bases neurobiológicas de la orientación sexual. En nuestra síntesis narrativa, destacamos temas importantes que sugieren que la exposición al estrés de las minorías puede estar asociada con la disminución de la activación y la conectividad funcional dentro de la red del modo por defecto (relacionada con el sentido del yo y la cognición social), y resumimos la evidencia preliminar relacionada con la dinámica neuronal aberrante dentro de la red de saliencia (involucrada en la detección de amenazas y el procesamiento del miedo) y la red ejecutiva central (involucrada en el funcionamiento ejecutivo y la regulación de las emociones). Es importante destacar que esto es paralelo a las adaptaciones neuronales comúnmente observadas entre los individuos con trastorno de estrés postraumático (TEPT) después del trauma y apoya la inclusión de formas insidiosas de trauma relacionadas con el estrés de las minorías dentro de los modelos de TEPT.Conclusiones: En conjunto, el estrés de las minorías puede tener varias vías neuropsicológicas compartidas con el TEPT y los trastornos relacionados con el estrés. Aquí, esbozamos una agenda de investigación detallada que proporciona una visión general de la literatura que vincula el estrés de las minorías sexuales con el TEPT y el trauma insidioso, el afecto moral (incluyendo la vergüenza y la culpa), y el riesgo/resiliencia de la salud mental, además del estrés de las minorías relacionadas con la raza, la etnia y el género. Por último, proponemos un marco de mosaico de minorías novedoso diseñado para informar sobre las futuras direcciones de la investigación de neuroimagen del estrés de las minorías desde una perspectiva interseccional.

Functional and cognitive impairment in the first episode of depression: A systematic review.

OBJECTIVES: To describe the cognitive and functional impairment in individuals with the first episode of major depressive disorder (MDD) as compared to controls and individuals with recurrent MDD. Also to describe the functional and cognitive trajectory after the first episode of MDD. METHODS: A total of 52 studies were included in our systematic review. 32 studies compared the cognitive performance between first episode of depression (FED) and controls, 11 studies compared the cognitive performance between recurrent depression (RD) and FED, 10 compared global functioning between RD and FED, four studies assessed cognition in FED over time, and two studies assessed global functioning in FED over time. RESULTS: The majority of studies (n = 22/32, 68.8%) found that FED subjects performed significantly worse than controls on cognitive tests, with processing speed (n = 12) and executive/working memory (n = 11) being the most commonly impaired domains. Seven out of 11 studies (63.6%) found that RD performed significantly worse than FED, with verbal learning and memory being the most commonly impaired domain (n = 4). Most studies (n = 7/10, 70%) did not find a significant difference in global functioning between RD and FED. In three of four longitudinal studies assessing cognition, subgroup analyses were used instead of directly assessing cognition in FED over time while the remaining study found significant cognitive declines over time in FED when compared to controls. The two longitudinal studies assessing functional trajectory found that functioning significantly improved over time, possibly due to the improvement of depressive symptoms. CONCLUSION: There is strong evidence that cognitive impairment is present during the first episode of depression, and individuals with multiple episodes display greater cognitive impairment than individuals with a single episode. Future studies aimed at identifying predictors of cognitive and functional impairment after the first episode of depression are needed to describe the functional and cognitive trajectory of individuals with the first episode of MDD over time.

Tobacco use among transgender and gender non-binary youth in Brazil.

Transgender and gender non-binary youth are particularly vulnerable to tobacco smoking and susceptible to smoking adverse health outcomes. That is, they are in special risk to start smoking and, after starting, they may face worse outcomes when comparing to their cisgender peers. Therefore, the present study aims to evaluate factors associated with tobacco use among transgender and gender non-binary youth. Brazilian youth aged 16 to 25 who identify as transgender or gender non-binary answered an online questionnaire. Poisson regression with robust variance was run to predict smoking cigarettes based on individual and environmental factors. 14.1% of 206 youth reported smoking cigarettes daily, whereas 9.3% of participants reported smoking e-cigarettes occasionally. Drug use, lack of social support, deprivation, discrimination, the wait for medical gender-affirming procedures and being outside school were associated with smoking cigarettes. Contextual and individual factors should be further explored in causal analysis and taken into consideration when planning smoking prevention and cessation interventions for transgender and gender non-binary youth.

Prevalence of Gender Dysphoria in Southern Brazil: A Retrospective Study.

To ensure that public health services provide comprehensive and inclusive health care to the general population, it is important for countries to estimate how many of their citizens experience gender dysphoria and wish to receive specialized hormone treatment or gender-affirming surgery. The aim of this study was to estimate the prevalence of individuals with gender dysphoria seeking transgender health care in a public teaching hospital in southern Brazil. In this retrospective follow-up study, we analyzed the medical records and sociodemographic data of individuals aged > 15 years living in Rio Grande do Sul, Brazil, that enrolled in a specialized program to receive hormone therapy and gender-affirming surgery between 2000 and 2018. This study is the first to attempt estimating the prevalence of gender dysphoria in Rio Grande do Sul; it describes novel data on the clinical profile of individuals with gender dysphoria treated in a public hospital specialized in providing transgender health care. Prevalence estimates were calculated based on statewide annual population data in the study period. Of 934 identified individuals, 776 (601 trans women and 175 trans men) were included in this study. The overall prevalence of individuals with gender dysphoria was 9.3 per 100,000 individuals (95% CI: 8.6 to 9.8). Meanwhile, there were 15 trans women per 100,000 people (95% CI: 14 to 16) and 4.1 trans men per 100,000 people (95% CI: 3.5 to 4.8). There was a progressive increase in the number of people seeking hormone therapy and gender-affirming surgery during the study period. Future research is needed to determine the size of the trans population in other regions of Brazil and to expand the knowledge regarding gender dysphoria to allow for the development of effective public policies for people with gender dysphoria.

Resumo Jovens transgêneros e não-binários são particularmente vulneráveis ao tabagismo e suscetíveis a seus malefícios a saúde. Ou seja, esses grupos estão em especial risco para começar a fumar e, após o início, tendem a apresentar resultados piores quando comparados a seus pares cisgêneros. Sendo assim, o presente estudo tem como objetivo avaliar fatores associados ao uso do tabaco em jovens transgêneros e não-binários. Jovens brasileiros, com idade entre 16 e 25 anos, que se identificam como transgêneros ou não-binários responderam um questionário on-line. Uma Regressão de Poisson com variância robusta foi realizada para predizer o consumo de cigarros com base em fatores individuais e ambientais. 14,1% de 206 jovens relataram fumar cigarros diariamente, enquanto 9,3% dos participantes revelaram fumar cigarros eletrônicos ocasionalmente. Uso de drogas, falta de suporte social, experiências de privação, discriminação, espera para procedimentos médicos de afirmação de gênero e evasão escolar foram associados ao consumo de cigarros entre jovens transgêneros e não-binários brasileiros. Sendo assim, os fatores individuais e contextuais citados devem receber especial enfoque no planejamento de intervenções de prevenção e interrupção do tabagismo voltados a jovens transgêneros e não-binários brasileiros.

Acoustic Measures of Brazilian Transgender Women's Voices: A Case-Control Study.

Objective: This study aims to compare the acoustic vocal analysis results of a group of transgender women relative to those of cisgender women. Methods: Thirty transgender women between the ages of 19 and 52 years old participated in the study. The control group was composed of 31 cisgender women between the ages of 20 and 48 years old. A standardized questionnaire was administered to collect general patient data to better characterize the participants. The vowel /a/ sounds of all participants were collected and analyzed by the Multi-Dimensional Voice Program advanced system. Results: Statistically significant differences between cisgender and transgender women were found on 14 measures: fundamental frequency, maximum fundamental frequency, minimum fundamental frequency, standard deviation of fundamental frequency, absolute jitter, percentage or relative jitter, fundamental frequency relative average perturbation, fundamental frequency perturbation quotient, smoothed fundamental frequency perturbation quotient, fundamental frequency variation, absolute shimmer, relative shimmer, voice turbulence index (lower values in the cases), and soft phonation index (higher values in the cases). The mean fundamental frequency value was 159.046 Hz for the cases and 192.435 Hz for the controls. Conclusion: Through glottal adaptations, the group of transgender women managed to feminize their voices, presenting voices that were less aperiodic and softer than those of cisgender women.

Factors Associated With Ruminative Thinking in Individuals With Gender Dysphoria.

This study aimed to examine psychosocial factors and medical history as well as symptoms of depression, anxiety, and stress associated with ruminative thinking in transgender people with gender dysphoria (GD) before undergoing gender affirmation surgery (GAS). This study evaluated 189 participants with GD (111 trans women and 78 trans men) from a specialized service for GAS in southern Brazil. Semi-structured interviews were conducted, and participants were asked to complete self-report questionnaires. We recovered participants' sociodemographic and psychosocial data (e.g., history of sexual abuse, expulsion from home, and history of drug use) and data regarding their clinical history (e.g., medication, history of suicidal ideation and attempted suicide, and HIV status). Further, we implemented the Depression, Anxiety and Stress Scale (DASS-21) to examine participants' psychological state, as well as the Ruminative Response Scale (RRS) to assess ruminative thinking, which includes brooding and reflection. The predictor variables were those that exhibited a minimum level of significance of p ≤ 0.05 in multivariate linear regression. The ruminative thinking scores for trans women were higher than those of trans men (Brooding p = 0.014; Reflection p = 0.052).In the multivariate model, suicidal ideation, moderate depression, and severe/very severe anxiety were associated with both brooding and reflection. Feminine gender identity and stress symptoms moderated only brooding, while anxiety symptoms moderated only reflection. Our findings show that trans women had the highest ruminative thinking scores, and that depression, anxiety, stress, and suicidal ideation were associated with ruminative thinking in total sample. Psychological symptoms should be examined in the context of gender affirmation surgery to minimize the possibility of adverse mental health outcomes. Follow-up studies are required to measure ruminative thinking levels more accurately and to identify its predictors.

The Neuroanatomy of Transgender Identity: Mega-Analytic Findings From the ENIGMA Transgender Persons Working Group.

BACKGROUND: In contrast to cisgender persons, transgender persons identify with a different gender than the one assigned at birth. Although research on the underlying neurobiology of transgender persons has been accumulating over the years, neuroimaging studies in this relatively rare population are often based on very small samples resulting in discrepant findings. AIM: To examine the neurobiology of transgender persons in a large sample. METHODS: Using a mega-analytic approach, structural MRI data of 803 non-hormonally treated transgender men (TM, n = 214, female assigned at birth with male gender identity), transgender women (TW, n = 172, male assigned at birth with female gender identity), cisgender men (CM, n = 221, male assigned at birth with male gender identity) and cisgender women (CW, n = 196, female assigned at birth with female gender identity) were analyzed. OUTCOMES: Structural brain measures, including grey matter volume, cortical surface area, and cortical thickness. RESULTS: Transgender persons differed significantly from cisgender persons with respect to (sub)cortical brain volumes and surface area, but not cortical thickness. Contrasting the 4 groups (TM, TW, CM, and CW), we observed a variety of patterns that not only depended on the direction of gender identity (towards male or towards female) but also on the brain measure as well as the brain region examined. CLINICAL TRANSLATION: The outcomes of this large-scale study may provide a normative framework that may become useful in clinical studies. STRENGTHS AND LIMITATIONS: While this is the largest study of MRI data in transgender persons to date, the analyses conducted were governed (and restricted) by the type of data collected across all participating sites. CONCLUSION: Rather than being merely shifted towards either end of the male-female spectrum, transgender persons seem to present with their own unique brain phenotype.

Gender dysphoria: prejudice from childhood to adulthood, but no impact on inflammation. A cross-sectional controlled study.

INTRODUCTION: Gender dysphoria (GD) is characterized by a marked incongruence between experienced gender and one's gender assigned at birth. Transsexual individuals present a higher prevalence of psychiatric disorders when compared to non-transsexual populations, and it has been proposed that minority stress, i.e., discrimination or prejudice, has a relevant impact on these outcomes. Transsexuals also show increased chances of having experienced maltreatment during childhood. Interleukin (IL)-1ß, IL-6, IL-10 and tumor necrosis factor-alpha (TNF-α) are inflammatory cytokines that regulate our immune system. Imbalanced levels in such cytokines are linked to history of childhood maltreatment and psychiatric disorders. We compared differences in IL-1ß, IL-6, IL-10 and TNF-α levels and exposure to traumatic events in childhood and adulthood in individuals with and without GD (DSM-5). METHODS: Cross-sectional controlled study comparing 34 transsexual women and 31 non-transsexual men. They underwent a thorough structured interview, assessing sociodemographic information, mood and anxiety symptoms, childhood maltreatment, explicit discrimination and suicidal ideation. Inflammatory cytokine levels (IL-1ß, IL-6, IL-10 and TNF-α) were measured by multiplex immunoassay. RESULTS: Individuals with GD experienced more discrimination (p = 0.002) and childhood maltreatment (p = 0.046) than non-transsexual men. Higher suicidal ideation (p < 0.001) and previous suicide attempt (p = 0.001) rates were observed in transsexual women. However, no differences were observed in the levels of any cytokine. CONCLUSIONS: These results suggest that transsexual women are more exposed to stressful events from childhood to adulthood than non-transsexual men and that GD per se does not play a role in inflammatory markers.

Breast cancer survivors living with chronic neuropathic pain show improved brain health following mindfulness-based stress reduction: a preliminary diffusion tensor imaging study.

PURPOSE: The present study explores the benefits of an 8-week mindfulness-based stress reduction (MBSR) program to white matter integrity among breast cancer survivors experiencing chronic neuropathic pain (CNP). METHODS: Twenty-three women were randomly assigned to either a MBSR treatment group (n = 13) or a waitlist control group (n = 10). Participants were imaged with MRI prior to and post-MBSR training using diffusion tensor imaging. RESULTS: Compared with controls, the MBSR group showed a significant increase in fractional anisotropy (FA), particularly in the left subcortical regions including the uncinate fasciculus, amygdala, and hippocampus, as well as in the external capsule and in the left sagittal stratum. No decreases to FA were found in any brain regions following MBSR training. The FA values also negatively correlated with the pain severity and pain interference scores from the BRIEF pain questionnaire. CONCLUSIONS: The present findings demonstrate that MBSR training may enhance the integrity of cerebral white matter that coincides with a reduction in pain perception. Further research with a larger sample size is required. IMPLICATIONS FOR CANCER SURVIVORS: This study highlights the potential for MBSR, as a non-pharmacological intervention, to provide both brain health improvement and pain perception relief for female breast cancer survivors experiencing CNP.

Gender Affirmation Is Associated with Transgender and Gender Nonbinary Youth Mental Health Improvement.

Purpose: The present study aimed to evaluate the impact of each domain of gender affirmation (social, legal, and medical/surgical) on the mental health of transgender and gender nonbinary youth. Methods: Three hundred fifty transgender boys, transgender girls, and gender nonbinary Brazilian youth, from 16 to 24 years old, answered an online survey. Results: The final sample consisted of 350 youth who participated in this study. A total of 149 (42.64%) youth identified as transgender boys, 85 (24.28%) identified as transgender girls, and 116 (33.14%) identified as gender nonbinary youth. The mean age was 18.61 (95% confidence interval 18.34-18.88) years. Having accessed multiple steps of gender affirmation (social, legal, and medical/surgical) was associated with fewer symptoms of depression and less anxiety. Furthermore, engaging in gender affirmation processes helped youth to develop a sense of pride and positivity about their gender identity and a feeling of being socially accepted. Conclusion: Enabling transgender and gender nonbinary youth to access gender affirmation processes more easily should be considered as a strategy to reduce depression and anxiety symptoms, as well as to improve gender positivity.

The Link between Estradiol and Neuroplasticity in Transgender Women after Gender-Affirming Surgery: A Bimodal Hypothesis.

For transgender individuals, gender-affirming surgery (GAS) and cross-sex hormone therapy (CSHT) are part of the gender transition process. Scientific evidence supporting the maintenance of CSHT after GAS-related gonadectomy is accumulating. However, few data are available on the impact of CSHT on the brain structure following hypogonadism. Thus, we aimed to investigate links between estradiol and brain cortical thickness (CTh) and cognition in 18 post-gonadectomy transgender women using a longitudinal design. For this purpose, the participants underwent a voluntary period of CSHT washout of at least 30 days, followed by estradiol re-institution for 60 days. High-resolution T1-weighted brain images, hormonal measures, working and verbal memory were collected at 2 time points: on the last day of the washout (t1) and on the last day of the 2-month CSHT period (t2). Between these 2 time points, CTh increased within the left precentral gyrus and right precuneus but decreased within the right lateral occipital cortex. However, these findings did not survive corrections of multiple comparisons. Nevertheless, there was a significant negative correlation between changes in estradiol levels and changes in CTh. This effect was evident in the left superior frontal gyrus, the left middle temporal gyrus, the right precuneus, the right superior temporal gyrus, and the right pars opercularis. Although there was an improvement in verbal memory following hypogonadism correction, we did not observe a significant relationship between changes in memory scores and CTh. Altogether, these findings suggest that there is a link between estradiol and CTh.

Use of the House-Tree-Person Projective Drawings and Parental Styles Inventory in the Global Psychological Evaluation of Transgender Youth Who Seek Healthcare at the Gender Identity Program.

The present study explores data collected in the psychological evaluation of transgender youth and their families who seek healthcare at the Gender Identity Program. Great psychosocial changes mark the transition from infancy to adulthood. Transgender youth may have these aspects of their developmental stage potentialized. A study was conducted with 23 transgender youth (mean age = 14 ± 2.38 years) and their caregivers. Eleven of the youngsters were assigned male at birth, while 12 were assigned female. The research protocol consisted of a survey and systematization of the data collected in the initial global psychological evaluation performed at the healthcare facility, including house-tree-person (HTP) projective drawings and the parental styles inventory. The present study aimed to explore the data collected during the psychological evaluation of youngsters diagnosed with gender incongruence, relating the HTP projective drawing technique to parental styles and gender trajectories. The results indicate two key points. One evidenced that parental styles could be either preventive or risk components in maintaining adequate socialization in these young people but not in affecting the level of gender dysphoria. The other was that coherence is introduced in the person's perception of his or her projected self-image and his or her expressed gender as he/she becomes more comfortable in expressing his/her gender identity. Treating youngsters inherently brings ethical issues to clinical practice. Thus, global psychological evaluation tailored to this population is a fundamental resource that the psychology professional can use in consultations with youngsters because this tool brings a global understanding about the natural development cycle, facilitating the formulation of therapeutic conducts and exchanges within interdisciplinary transgender health care teams.

Effects of Estradiol Therapy on Resting-State Functional Connectivity of Transgender Women After Gender-Affirming Related Gonadectomy.

An extreme incongruence between sex and gender identity leads individuals with gender dysphoria (GD) to seek cross-sex hormone therapy (CSHT), and gender-affirming surgery (GAS). Although few studies have investigated the effects of CSHT on the brain prior to GAS, no studies in the extant literature have evaluated its impact during hypogonadism in post-GAS individuals. Here, we aimed to evaluate the effects of estradiol on resting-state functional connectivity (rs-FC) of the sensorimotor cortex (SMC) and basal ganglia following surgical hypogonadism. Eighteen post-GAS (male-to-female) participants underwent functional magnetic resonance imaging (fMRI) and neuropsychiatric and hormonal assessment at two time points (t1, hormonal washout; t2, CSHT reintroduction). Based on the literature, the thalamus was selected as a seed, while the SMC and the dorsolateral striatum were targets for seed-based functional connectivity (sbFC). A second sbFC investigation consisted of a whole-brain voxel exploratory analysis again using the thalamus as a seed. A final complementary data-driven approach using multivoxel pattern analysis (MVPA) was conducted to identify a potential seed for further sbFC analyses. An increase in the rs-FC between the left thalamus and the left SCM/putamen followed CSHT. MVPA identified a cluster within the subcallosal cortex (SubCalC) representing the highest variation in peak activation between time points. Setting the SubCalC as a seed, whole-brain analysis showed a decoupling between the SubCalC and the medial frontal cortex during CSHT. These results indicate that CSHT with estradiol post-GAS, modulates rs-FC in regions engaged in cognitive, emotional, and sensorimotor processes.

Dealing with gender-related and general stress: Substance use among Brazilian transgender youth.

INTRODUCTION: Adolescent substance use is a major public health concern since it enhances adolescent morbidity and mortality, affecting adulthood health and well-being. Although current evidence shows a high risk for substance use among transgender populations, to date, few studies evaluate substance use among transgender youth. METHOD: Brazilian transgender youth (ages between 16 and 25 years old) answered an online questionnaire measuring demographics, substance use and modifiable factors associated with drug use to deal with general stress, gender-related stress, and recreational use. RESULTS: Cannabis was the most frequent substance used among transgender youth (20.88%; CI 95% 23.71-36.19), whereas 11.45% (CI 95% 11.38-21.47) of volunteers disclosed use of pain medication, such as codeine, and 5.05% (CI 95% 3.71-10.78) revealed use of sedatives and tranquilizers in the last 30 days. ADH medication (not prescribed), as well as cocaine and other drugs (such as antihistamines and Hookah), was also reported by 2.36% (CI 95% 0.92-5.84), 2.69% (CI 95% 1.24-6.49) and 4.04% (CI 95% 2.61-8.98) of transgender youth. CONCLUSION: A logistic regression model showed that discrimination and home instability were the primary determinants of vulnerable to substance use among youth. Therefore, the harm reduction strategies must affect the social and physical aspects of transgender youth lives.

A Retrospective Review of Medical Records of Laboratory-Tested Sexually Transmitted Infections of Transsexual Men from Southern Brazil.

The present study assessed the prevalence of sexually transmitted infections (STIs) in 90 transsexual men (female-to-male transsexual persons) from southern Brazil. A retrospective review of the medical records of all transsexual men who visited an outpatient clinic in Rio Grande do Sul from 1998 to 2017 was performed. Although the sample had a high prevalence of risk factors for contracting STIs, such as drug use, one-third of the participants had never been tested for STIs and, when screened, it was mostly for HIV, but not for syphilis or other STIs. Based only on laboratory-tested transsexual men, the prevalence of syphilis and hepatitis C was 3.4% and 1.6%, respectively, which is higher than the general population. It is clear that health professionals need to broaden their understanding of transsexual men, acknowledging STIs as a possible diagnosis.

Cortical thickness in major depressive disorder: A systematic review and meta-analysis.

Neuroimaging studies assessing neurobiological differences between patients with major depressive disorder (MDD) and healthy controls (HC) are often hindered by small sample sizes and heterogeneity of the patient sample. We performed a comprehensive literature search for studies assessing cortical thickness between patient and control groups, including studies investigating treatment effects on cortical thickness. We identified 34 studies meeting criteria for the systematic review and used Seed-based d Mapping to meta-analyze 24 of those that met additional criteria. Analysis of the full sample of subjects (MDD = 1073; HC = 936) revealed significant thinning in the MDD group in the bilateral orbitofrontal gyrus (BA 11), left pars opercularis (BA 45) and left calcarine fissure/lingual gyrus (BA 17), as well as an area of significant thickening in the left supramarginal gyrus (BA 40). These results support other imaging modalities that report disruptions in various frontal and temporal areas in MDD and identify additional areas in all major cerebral lobes likely to be significant when parsing for biomarkers of treatment or relapse.
