The PrEP cascade in a sample of HIV-negative or unknown status adolescent and young adult transgender women in Peru.

Background: Transgender women are a key population in the HIV epidemic globally, including in Peru. This cross-sectional epidemiological study characterized the pre-exposure prophylaxis (PrEP) cascade in adolescent and young adult transgender women in Peru to inform roll-out of early HIV prevention efforts.

Methods: Between February-July 2022, a community-recruited sample of HIV-negative or status unknown young transgender women ( = 140) in Peru completed a socio-behavioral survey and biological testing for HIV and bacterial STIs.

HIV vulnerabilities and psychosocial health among young transgender women in Lima, Peru: results from a bio-behavioural survey.

Introduction: Peruvian young transgender women (YTW) ages 16-24 years are a critical but understudied group for primary HIV prevention efforts, due to sharp increases in HIV prevalence among TW ages 25 years and older.

Methods: Between February and July 2022, a cross-sectional quantitative study with YTW ages 16-24 years in Peru (N = 211) was conducted consisting of a bio-behavioural survey accompanied by laboratory-based testing for HIV and sexually transmitted infections (STIs). Bivariate and multivariable Poisson regression models were used to estimate prevalence ratios between socio-demographic and behavioural characteristics and HIV status.

External quality assessment to support the WHO ProSPeRo study for the evaluation of two dual HIV/syphilis point-of-care tests in seven countries.

Background: Sexually transmitted infections (STIs) such as syphilis and HIV remain to be a significant public health issue worldwide. Dual rapid point-of-care tests (POCTs) have shown promise for detecting antibodies to HIV and syphilis but have not been fully evaluated in the field. Our study supported the WHO ProSPeRo study on Sexually Transmitted Infection Point-of-Care Testing (STI POCT) by providing external quality assessment (EQA) for HIV and syphilis testing in reference laboratories and their associated clinical sites in seven countries.

Latin America at the margins? Implications of the geographic and epistemic narrowing of 'global' health.

To explore the narrowing of the concept of 'global' in global health, this article traces how Latin America has held a place of both privilege and power as well as marginalisation in the field. We employ a modified extended case method to examine how Latin America has been 'seen' and 'heard' in understandings of global health, underscoring the region's shifting role as a key site for research and practice in 'tropical medicine' from the mid-nineteenth century through World War II, to a major player and recipient of development assistance throughout the 'international health' era after World War II until the late twentieth century, to a region progressively marginalised within 'global health' since the mid-1980s/1990s. We argue that the progressive marginalisation of Latin America and Southern theory has not only hurt health equity and services, but also demonstrates the fundamental flaws in contemporary 'global' thinking.

Intersectional stigma and the arc of intranational migration: experiences of transgender adolescents and women who migrate within Peru.

Background: Migration is recognized as a key determinant of health. Yet, limited research addresses the arc of intranational migration and, even less, the experiences of transgender (trans) adolescents and women migrants and the associated health vulnerabilities. Using intersectional stigma as a theoretical frame, this study seeks to better understand the sexual health vulnerabilities and needs of trans women migrants in Peru.

Awareness, knowledge, and attitudes related to HIV pre-exposure prophylaxis and other prevention strategies among physicians from Brazil and Mexico: cross-sectional web-based survey.

Background: In order to end the HIV epidemic by 2030, combination HIV prevention including pre-exposure prophylaxis (PrEP) should be widely available, especially for the most vulnerable populations. In Latin America and the Caribbean (LAC), only 14 out of 46 countries have access to PrEP. In Brazil and Mexico, PrEP has been provided at no cost through the Public Health System since 2017 and 2021, respectively.

The Peruvian COVID-19 vaccine scandal and re-thinking the path to public trust.

In February 2021, the Peruvian 'vaccinegate' scandal broke when the media reported that nearly 500 experimental doses of an ongoing COVID-19 trial were given to key individuals not enrolled in the trial. Indeed, vaccine doses were administered to leading politicians, such as the former President and his wife, and other high-level health officials and academic leaders at the universities overseeing ethical compliance and administration of the trial. The 'vaccinegate' scandal in Peru is but one example of how the lack of a coordinated global response to COVID-19 has allowed countries to act in the best interest of some, ultimately, failing to secure a democratic approach to the right to health for all during a global pandemic.

Vaccines for all? A rapid scoping review of COVID-19 vaccine access for Venezuelan migrants in Latin America.

Introduction: The entangled health and economic crises fueled by COVID-19 have exacerbated the challenges facing Venezuelan migrants. There are more than 5.6 million Venezuelan migrants globally and almost 80% reside throughout Latin America.

"Existimos": Health and social needs of transgender men in Lima, Peru.

Background: The health of transgender men (trans men)-individuals who identify as men and were assigned a female sex assigned at birth-is overlooked globally. This mixed-methods exploratory study sought to understand the lived experiences, health, and social needs of trans men in Lima, Peru to bring visibility to specific health needs and inform responsive and holistic public health efforts.

Methods: Between July 2016-January 2017, 46 trans men in Lima, Peru participated in a mixed-methods study.

Analysis of Male Couples' Sexual Agreements After Using an eHealth, Couples-Based HIV Prevention Intervention in Lima, Peru.

Few studies have investigated the composition of male couples' sexual agreements and whether their agreement composition differs by dyad HIV serostatus. To help assess the utility that agreements could have for sexual health and prevention, the present study analyzed dyadic paradata collected from an acceptability project of an eHealth HIV prevention toolkit intervention with 42 male couples in Lima, Peru (16 serodiscordant, 12 seroconcordant positive, 14 seroconcordant negative). Couples used the toolkit as designed, which included an agreement builder activity to encourage formation of a tailored agreement by selecting items from five categories (wellness, sex with partner, sex with others, social etiquette, substance use).

Do Subjective Alcohol Screening Tools Correlate with Biomarkers Among High-Risk Transgender Women and Men Who Have Sex with Men in Lima, Peru?

Alcohol abuse can influence sexual risk behavior; however, its measurement is not straightforward. This study compared self-reported alcohol use, via the AUDIT and CAGE, with levels of phosphatidylethanol (Peth), a phospholipid biomarker that forms with chronic, heavy drinking, among high-risk MSM and TW in Lima, Peru. Chi square, Fisher's exact, Wilcoxon ranksum tests compared the instruments.
