Introduction: The ability to objectively measure chronic stress has important implications for research, prevention, and treatment. Cortisol is currently the most used biological marker in the investigation of stress and can be measured via blood, saliva, and urine; however, these methods have disadvantages. The measurement of cortisol in hair is a more recently developed method that quantifies the cumulative production of cortisol over longer periods of time.

Objective: To analyze the experiences of transgender women and travestis regarding the use of hormones for body changes without a medical prescription.
Methods: This is a cross-sectional, quantitative and qualitative study, using data from "TransOdara", which estimated the prevalence of Sexually Transmitted Infections in transgender women and travestis recruited through Respondent-Driven Sampling, between December 2019 and July 2021, in São Paulo, Campo Grande, Manaus, Porto Alegre, and Salvador, Brazil. The main outcome was: use of hormones without medical prescription and associated risk factors.

Objective: This study aimed to determine the acceptability and factors associated with uptake of a physical examination for the detection of symptomatic sexually transmitted infections (STIs) by transgender women and travestis in Brazil.
Methods: TransOdara was a multi-centric, cross-sectional STI prevalence study conducted among transgender women and travestis in five capital cities (Campo Grande, Manaus, Porto Alegre, Salvador and São Paulo) representing all Brazilian regions, between December 2019 and July 2021. A total of 1,317 self-identified transgender women and travestis aged ≥18 years were recruited using respondent-driven sampling and responded to a standard questionnaire.
Objective: To investigate the prior testing for HIV, syphilis, hepatitis B (HBV), and hepatitis C (HCV) among transgender women and travestis (TGW) in five Brazilian cities and identify factors associated with each of these previous tests.
Methods: This is a cross-sectional study with the recruitment of TGW through respondent-driven sampling (TransOdara Study). The investigated outcome variable was prior testing for HIV, syphilis, HBV, and HCV in the last 12 months.
Objective: To understand the narratives of transgender women and travestis (TGW) from four Brazilian cities regarding access to and use of health services.
Methods: Qualitative study carried out within the scope of the TransOdara project, cross-sectional multicenter mixed methods research conducted between 2019-2021. Fifty-two in-depth interviews with TGW in Manaus, Campo Grande, Porto Alegre and São Paulo were analyzed.
Objective: To estimate the prevalence and factors associated with hepatitis A, B, and C in transgender women and travestis's networks, in 5 regions of Brazil.
Methods: This cross-sectional study includedtransgender women and travestis in five Brazilian capitals (Campo Grande, Manaus, Porto Alegre, Salvador, and São Paulo), between December/2019 and July/2021. All samples were subjected to detection of serological markers of hepatitis virus A (HAV), B (HBV), and C (HCV) infections through rapid tests and chemiluminescent microparticle immunoassays.
Objective: The aim of this study was to investigate the prevalence of human immunodeficiency virus (HIV) infection among transgender women and travestis and to analyze factors associated with HIV infection in Brazil.
Methods: TransOdara was a cross-sectional study on sexually transmitted infections among transgender women and travestis in five Brazilian cities between 2019 and 2021. Self-identified transgender women and travestis aged ≥18 years were recruited using respondent-driven sampling, completed an interviewer-led questionnaire, and provided samples to detect HIV.
Objective: The study aimed to estimate the prevalence of acquired syphilis and associated factors in a national survey.
Methods: TransOdara was a cross-sectional study comprising transgender women and travestis (TGW) in five major cities in Brazil during December of 2019 and July of 2021. The sample was recruited using the respondent-driven sampling (RDS) method.
Objective: Sexually transmitted infections (STIs) disproportionately affect transgender women and travestis (TGW), who often lack access to healthcare due to stigma and discrimination. We describe the approach and methodology of a study investigating the prevalence of syphilis, HIV, hepatitis A, B, and C, Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), and human papillomavirus (HPV) among TGW, as well as their knowledge and perceptions regarding syphilis, to better inform policies to curb STIs among this vulnerable population.
Methods: TransOdara was a multicentric, cross-sectional study conducted among TGW in five capital cities from major Brazilian regions between December 2019 and July 2021.
Introduction: Globally, transgender ('trans') women experience extreme social and economic marginalisation due to intersectional stigma, defined as the confluence of stigma that results from the intersection of social identities and positions among those who are oppressed multiple times. Among trans women, gender-based stigma intersects with social positions such as engagement in sex work and substance use, as well as race-based stigma to generate a social context of vulnerability and increased risk of HIV acquisition. In Brazil, trans women are the 'most at-risk' group for HIV, with 55 times higher estimated odds of HIV infection than the general population; further, uptake of HIV testing and pre-exposure prophylaxis (PrEP) among trans women is significantly lower than other at-risk groups.

Background: Information concerning the impact of the COVID-19 health crisis on populations most affected by HIV and hepatitis C virus (HCV; or key populations [KP]), and those working with these populations in community settings, is limited. Community-based organizations working in the field of HIV and viral hepatitis are well placed to identify and meet the new needs of KP owing to the health crisis.
