Article Synopsis
- Men who have sex with men (MSM) are at a high risk for oral HPV infection, but there are no specific guidelines for screening them; this study aimed to estimate the prevalence of oral high-risk HPV among MSM and create a risk score for identifying those at higher risk.
- In a study involving 500 MSM attending STD clinics, the prevalence of oral high-risk HPV was found to be 11.1%, with higher rates in HIV-positive individuals. Key risk factors identified included being over 40 years old, having a CD4 count between 200-499, and recent use of recreational vasodilators.
- The developed risk score effectively distinguishes MSM at higher risk for oral HPV, which can be utilized by clinicians to prioritize vaccinations
Article Synopsis
- - The study focused on the high prevalence of high-risk human papillomavirus (hrHPV) infection among transgender women, particularly examining differences based on sex work history.
- - Conducted in Mexico City with 207 transgender women aged 18-60 without prior HPV vaccination, the study found that hrHPV prevalence was 62.0% in those with a history of sex work and 52.0% in those without, with 26.6% also living with HIV.
- - Findings indicated that various sexual behaviors, not just sex work, contribute to hrHPV prevalence, highlighting the need for comprehensive HPV prevention programs for all transgender women regardless of their sex work involvement.

Our aim was to better understand Human Papillomavirus (HPV) vaccine acceptance among Mexican adults including people with and without HIV, cisgender men who have sex with men (MSM) or with women (MSW), cisgender and transgender women. A computer-assisted, self-administered questionnaire was completed by healthcare users and participants recruited through community organizations, and the first dose of the quadrivalent HPV vaccine was offered at no cost at a large sexual health clinic in Mexico City, from May to December 2018. Socio-demographic characteristics and factors associated with HPV vaccine acceptance were analyzed using logistic regression.

Materials And Methods: This mixed methods study evaluates the effectiveness of a combined vaccination-screening strategy to reduce HPV prevalence/incidence and occurrence of cervical intraepithelial neoplasms grade 2+ and/or anal intraepithelial neoplasms grade 2+, using Kaplan-Meier. The time-to-event method will evaluate time from positive results for specific anogenital HPV to incidence of anogenital lesions containing that HPV type.
Objective: To measure HPV vaccine acceptance in diverse Mexican adult popula-tions, taking into account HIV status.
Materials And Methods: A total of 1 329 men and women, with and without HIV, participated in one of three intervention studies, offering HPV vaccination, carried out in the states of Morelos, Tlaxcala and Mexico City; either the bivalent (Morelos n=103, Tlaxcala n=127) or quadrivalent HPV-vaccine (Mexico City n=1 099) was offered.
Results: HPV vaccine was accepted by 80.
