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).

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.

Heterogeneity in gender dysphoria in a Brazilian sample awaiting gender-affirming surgery: a data-driven analysis
Background: Population heterogeneity and the lack of clinical and sociodemographic information in transgender individuals with gender dysphoria (GD) remains a challenge for specialized services in mental health and surgical procedures. It aimed to identify and describe profiles in a sample waiting for gender-affirming surgery. Methods: A sample of 100 outpatients with GD was assessed through a structured interview, Emotion Regulation Difficulty Scale (DERS), Ruminative Response Scale (RRS), Depression, Anxiety and Stress Scale (DASS-21) and Life Satisfaction scale (SWLS). Cluster analysis was used to identify different profile categories. Results: Two subgroups with different profiles were identified: with less clinical severity (LCS) and with high clinical severity (HCS) on emotional dysregulation, acute symptoms of depression, anxiety, stress and association with mental rumination. The HCS cluster had greater vulnerability in terms of psychiatric history, use of psychotropic drugs, HIV positive, child abuse and suicidal behavior. Conclusion: Different profiles were found regarding the vulnerability to mental health in a sample of transgender people with GD who seek a public hospital service for the same clinical-surgical objective. Longitudinal studies are essential to monitor the impact of these contrasts and to target personalized therapeutic approaches in the prevention of psychiatric disorders.

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.

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.

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.

Sintomas internalizantes, externalizantes e relações interpessoais de adolescentes em tratamento para dependência química
O uso de drogas na adolescência produz importantes impactos psicológicos, comportamentais e nos estilos interpessoais do individuo. Este estudo visou examinar e descrever tais aspectos através do instrumento Young Self Report (YSR), uma entrevista clínica semi-estruturada e uma sessão de grupo focal com cinco adolescentes internados pela a dependência de drogas. O discurso dos participantes foi analisado através da Análise de Conteúdo de Bardin, modalidade temática e as sintomatologias clínicas examinadas pelo YSR. O conteúdo do grupo obteve seis categorias finais: habilidades interpessoais, dificuldades interpessoais, aspectos emocionais, aspectos físicos, ambiente escolar e ambiente familiar. Os resultados mostraram características importantes no funcionamento adaptativo, que facilita as relações e problemas clínicos que podem estar associados a estilos menos adaptativos. Este estudo destaca a importância de avaliar os elementos individuais envolvidos na dependência das drogas e no plano terapêutico, bem como, sugerir modelos de intervenções que atendem a essas demandas.

Brain Maturation, Cognition and Voice Pattern in a Gender Dysphoria Case under Pubertal Suppression
Introduction: Gender dysphoria (GD) (DMS-5) is a condition marked by increasing psychological suffering that accompanies the incongruence between one's experienced or expressed gender and one's assigned gender. Manifestation of GD can be seen early on during childhood and adolescence. During this period, the development of undesirable sexual characteristics marks an acute suffering of being opposite to the sex of birth. Pubertal suppression with gonadotropin releasing hormone analogs (GnRHa) has been proposed for these individuals as a reversible treatment for postponing the pubertal development and attenuating psychological suffering. Recently, increased interest has been observed on the impact of this treatment on brain maturation, cognition and psychological performance. Objectives: The aim of this clinical report is to review the effects of puberty suppression on the brain white matter (WM) during adolescence. WM Fractional anisotropy, voice and cognitive functions were assessed before and during the treatment. MRI scans were acquired before, and after 22 and 28 months of hormonal suppression. Methods: We performed a longitudinal evaluation of a pubertal transgender girl undergoing hormonal treatment with GnRH analog. Three longitudinal magnetic resonance imaging (MRI) scans were performed for diffusion tensor imaging (DTI), regarding Fractional Anisotropy (FA) for regions of interest analysis. In parallel, voice samples for acoustic analysis as well as executive functioning with the Wechsler Intelligence Scale (WISC-IV) were performed. Results: During the follow-up, white matter fractional anisotropy did not increase, compared to normal male puberty effects on the brain. After 22 months of pubertal suppression, operational memory dropped 9 points and remained stable after 28 months of follow-up. The fundamental frequency of voice varied during the first year; however, it remained in the female range. Conclusion: Brain white matter fractional anisotropy remained unchanged in the GD girl during pubertal suppression with GnRHa for 28 months, which may be related to the reduced serum testosterone levels and/or to the patient's baseline low average cognitive performance.Global performance on the Weschler scale was slightly lower during pubertal suppression compared to baseline, predominantly due to a reduction in operational memory. Either a baseline of low average cognition or the hormonal status could play a role in cognitive performance during pubertal suppression. The voice pattern during the follow-up seemed to reflect testosterone levels under suppression by GnRHa treatment.

Gender incongruence: a comparative study using ICD-10 and DSM-5 diagnostic criteria
Objective: To compare the presence of criteria listed in the DSM-5 and ICD-10 diagnostic manuals in a Brazilian sample of transgender persons seeking health services specifically for physical transition. Methods: This multicenter cross-sectional study included a sample of 103 subjects who sought services for gender identity disorder in two main reference centers in Brazil. The method involved a structured interview encompassing the diagnostic criteria in the two manuals. Results: The results revealed that despite theoretical disagreement about the criteria, the manuals overlap regarding diagnosis confirmation; the DSM-5 was more inclusive (97.1%) than the ICD-10 (93.2%) in this population. Conclusions: Although there is no consensus on diagnostic criteria on transgenderism in the diversity of social and cultural contexts, more comprehensive diagnostic criteria are evolving due to society's increasing inclusivity.
