Acceptability and Usability of Self-Sampling for the Detection of Sexually Transmitted Infections Among Transgender Women: The TransOdara Multicentric Study in Brazil.

BACKGROUND: The effective testing of sexually transmitted infections (STIs) requires sampling from potential infection sites. This study aimed to assess the choice, satisfaction, and performance of self-collected samples (SCS) from potential infection sites for STI testing among transgender women in Brazil. METHODS: TransOdara was a multicentric, cross-sectional STI prevalence study conducted in 5 Brazilian cities. Using respondent-driven sampling, 1317 transgender women 18 years or older were recruited. Participants completed interviewer-led questionnaires and provided swab samples from multiple sites (anorectal, oropharyngeal, genital) for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and human papillomavirus (HPV) testing. Participants were given a choice of SCS or provider-collected samples (PCS) at each site. RESULTS: Most participants selected SCS for anorectal (74.9%; 95% confidence interval [CI], 72.4-77.3) and genital (72.7%; 95% CI, 70.2-75.1) sites, whereas fewer chose for oropharyngeal samples (49.8%; 95% CI, 47.0-52.6). For future testing, most participants expressed a preference for SCS for genital (72.2%; 95% CI, 69.5-74.7) and anorectal (70.2%; 95% CI, 67.6-72.7) sites. There was no significant difference in the positive test results for CT and NG between SCS and PCS at anorectal and oropharyngeal sites, or for HPV at anorectal and genital (penile or neovaginal) sites. CONCLUSIONS: This study demonstrated a high level of acceptability and usability of self-sampling for STI testing among transgender women. A preference for SCS was evident at the anorectal and genital sites, and the results of SCS were comparable to those of PCS. The findings suggest that multisite STI testing utilizing self-collection methods as a provided option can be effectively integrated into sexual health services for transgender women.

Dengue Outbreak Response during COVID-19 Pandemic, Key Largo, Florida, USA, 2020.

We report a dengue outbreak in Key Largo, Florida, USA, from February through August 2020, during the COVID-19 pandemic. Successful community engagement resulted in 61% of case-patients self-reporting. We also describe COVID-19 pandemic effects on the dengue outbreak investigation and the need to increase clinician awareness of dengue testing recommendations.

Hepatitis C virus prevalence among men who have sex with men: a cross-sectional study in 12 Brazilian cities.

BACKGROUND: Despite the preventive policies adopted, reduction in sexually transmitted infections (STIs) among men who have sex with men (MSM) has been limited. The risk of hepatitis C virus (HCV) infection has increased among the most vulnerable population groups, including MSM. The aim of this study was to estimate the prevalence of HCV infection and to assess risky practices among MSM from 12 Brazilian cities. METHODS: This study was carried out from June to December 2016 using respondent driven sampling (RDS). Participants completed a self-administered questionnaire to collect behavioral, socioeconomic, and demographic variables. In addition, the rapid diagnostic test (RDT) for HCV was offered. Positive results were sent to Instituto Adolfo Lutz for confirmation. RESULTS: A total of 4,176 participants were recruited and 23 samples were sent for confirmation. Of these, 16 were confirmed, resulting in a prevalence of 0.7% (95% CI: 0.3%-1.7%). The Southeast region showed a prevalence of 0.9% (95% CI: 0.3-2.6), followed by the South region, with 0.6% (95% CI: 0.2-2.1). The Northeast region had a prevalence of 0.3% (95% CI: 0.1-1.0) and the Midwest 0.1% (95% CI: 0.0-0.7). No positive cases were found in the North. Single men aged 40 years or older were the majority of participants exposed to HCV. High levels of alcohol consumption, illicit drug use, irregular condom use, in addition to infection with other STIs, were associated with exposure to HCV. CONCLUSIONS: STIs continue to be important health problems in Brazil and globally. Many STIs are inapparent for many years until they bring more serious consequences. Extra investment in HCV is also warranted, given that it can be eliminated. Relying solely on clinical data to provide information about inapparent infection, especially in stigmatized populations, will make that goal more difficult to achieve. Surveillance studies, such as the one reported here need to be repeated over time to demonstrate trends and to provide information for evaluation, program and policies. Investments in the most vulnerable populations are critical to achieve the World Health Organization global health goals including the elimination of viral hepatitis by 2030.

Perceived Risk of HIV Infection and Acceptability of PrEP among Men Who Have Sex with Men in Brazil.

The HIV epidemic affects men who have sex with men (MSM) disproportionally in Brazil, and pre-exposure prophylaxis (PrEP) is effective for preventing HIV in this population. However, low perceived risk of HIV may influence the acceptability and decision to use PrEP. This study estimated the association between self-perception of HIV risk and acceptability of daily oral PrEP among Brazilian MSM. Respondent-driven sampling (RDS) was used for behavioral and biological surveillance to recruit 4,176 MSM 18 years or over in 12 Brazilian cities in 2016. Results were weighted using Gile's estimator in RDS Analyst software. Adjusted odds rations (OR) with 95% confidence intervals were calculated using multivariate logistic regression. Acceptability of daily oral PrEP was high (69.7%) among the 3,544 MSM available for analysis. Most participants self-reported low or moderate risk of HIV infection (67.2%) and a small proportion (9.3%) reported high risk. A dose-response relationship was observed between acceptability of PrEP and self-reported risk: PrEP acceptability was 1.88 times higher (OR 1.8; 95% CI: 1.24-2.85) among MSM whose perceived risk of HIV infection was low or moderate, and 5 times higher (OR 5.68; 95% CI: 2.54-12.73) among those who self-reported high risk compared to MSM reporting no HIV risk. MSM with the highest risk perception of HIV reported higher rates of PrEP acceptability. Given the availability of daily oral PrEP in the public health care system in Brazil, we suggest emphasizing counseling about self-perception of HIV risk as part of routine HIV prevention services.

Genome maintenance functions of a putative Trypanosoma brucei translesion DNA polymerase include telomere association and a role in antigenic variation.

Maintenance of genome integrity is critical to guarantee transfer of an intact genome from parent to offspring during cell division. DNA polymerases (Pols) provide roles in both replication of the genome and the repair of a wide range of lesions. Amongst replicative DNA Pols, translesion DNA Pols play a particular role: replication to bypass DNA damage. All cells express a range of translesion Pols, but little work has examined their function in parasites, including whether the enzymes might contribute to host-parasite interactions. Here, we describe a dual function of one putative translesion Pol in African trypanosomes, which we now name TbPolIE. Previously, we demonstrated that TbPolIE is associated with telomeric sequences and here we show that RNAi-mediated depletion of TbPolIE transcripts results in slowed growth, altered DNA content, changes in cell morphology, and increased sensitivity to DNA damaging agents. We also show that TbPolIE displays pronounced localization at the nuclear periphery, and that its depletion leads to chromosome segregation defects and increased levels of endogenous DNA damage. Finally, we demonstrate that TbPolIE depletion leads to deregulation of telomeric variant surface glycoprotein genes, linking the function of this putative translesion DNA polymerase to host immune evasion by antigenic variation.

Factors associated with loss to follow up among HIV-exposed children: a historical cohort study from 2000 to 2017, in Porto Alegre, Brazil.

BACKGROUND: There are many inequalities in terms of prevention and treatment for pregnant women with HIV and exposed children in low and middle-income countries. The Brazilian protocol for prenatal care includes rapid diagnostic testing for HIV, compulsory notification, and monitoring by the epidemiological surveillance of children exposed to HIV until 18 months after delivery. The case is closed after HIV serology results are obtained. Lost to follow-up is defined as a child who was not located at the end of the case, and, therefore, did not have a laboratory diagnosis. Lost to follow-up is a current problem and has been documented in other countries. This study analyzed factors associated with loss to follow-up among HIV-exposed children, including sociodemographic, behavioral, and health variables of mothers of children lost to follow-up. METHODS: This historical cohort study included information on mothers of children exposed to HIV, born in Porto Alegre, from 2000 to 2017. The research outcome was the classification at the end of the child's follow-up (lost to follow-up or not). Factors associated with loss to follow-up were investigated using the Poisson regression model. Relative Risk calculations were performed. The significance level of 5% was adopted for variables in the adjusted model. RESULTS: Of 6,836 children exposed to HIV, 1,763 (25.8%) were classified as lost to follow-up. The factors associated were: maternal age of up to 22 years (aRR 1.25, 95% CI: 1.09-1.43), the mother's self-declared race/color being black or mixed (aRR 1.13, 95% CI: 1.03-1.25), up to three years of schooling (aRR 1.45, 95% CI: 1.26-1.67), between four and seven years of schooling (aRR 1.14, 95% CI: 1.02-1.28), intravenous drug use (aRR 1.29, 95% CI: 1.12-1.50), and HIV diagnosis during prenatal care or at delivery (aRR 1.37, 95% CI: 1.24-1.52). CONCLUSION: Variables related to individual vulnerability, such as race, age, schooling, and variables related to social and programmatic vulnerability, remain central to reducing loss to follow-up among HIV-exposed children.

RAPIDO: Promoting stroke awareness among Spanish speakers.

ABSTRACT: The mnemonic BE-FAST (Balance, Eyes, Face, Arm, Speech, Time) has been developed for the public to better remember and identify the warning signs of stroke. However, discrepancies may arise when translating stroke educational materials from English to Spanish. This article discusses the use of a culturally tailored tool, RAPIDO, to raise stroke awareness in Spanish-speaking populations.

Acceptability of HIV self-testing is low among men who have sex with men who have not tested for HIV: a study with respondent-driven sampling in Brazil.

BACKGROUND: Brazil has many people living with HIV (PLWH) who are unaware of their serostatus. The public health system has recently added HIV self-testing (HIVST) for key populations such as men who have sex with men (MSM). This study estimates HIVST acceptability among Brazilian MSM and explores factors associated with acceptability among MSM who have never tested for HIV or who had a previous negative result. METHODS: Respondent-driven sampling (RDS) was used to recruit 4176 MSM in 12 Brazilian cities in 2016 to this biological and behavioral surveillance study. We excluded from this analysis all MSM who were aware of their positive HIV serostatus. Descriptive, bivariate and multivariate analyses were conducted. Overall proportions were weighted with Gile's estimator in RDS Analyst software and 95% confidence intervals were calculated. The analyses of HIVST acceptability were stratified by prior HIV testing (never or one or more times). RESULTS: For this analysis, 3605 MSM were included. The acceptability of HIVST was 49.1%, lower among those who had never tested for HIV (42.7%) compared to those who had a previous HIV negative test (50.1%). In the subgroup of MSM who had never tested for HIV, those who reported discrimination or who had a medical appointment in the last 12 months reported higher HIVST acceptability. Among MSM who had a previous negative HIV test, only those reporting condomless receptive anal sex reported higher HIVST acceptability. In addition, we observed that high levels of knowledge of HIV/AIDS, taking part in lesbian, gay, bisexual, and transgender nongovernmental organizations (LGBT-NGO), or complete secondary or incomplete higher undergraduate education reported higher acceptability. CONCLUSIONS: The acceptability of HIVST was low among MSM, especially among those who never tested for HIV. Given access to HIVST in Brazil, we point to the need for programs that enhance promotion of testing addressed to MSM.

The use of a task through virtual reality in cerebral palsy using two different interaction devices (concrete and abstract) - a cross-sectional randomized study.

BACKGROUND: Cerebral Palsy (CP) is characterised by variable difficulties in muscular action, resulting in inability of the individual to perform functional movement. An option to provide functionality to the individual with CP is the use of computer innovation. The aim of this paper was to verify if there was any performance improvement in a task performed in a virtual environment and if there was transfer to the task performed in the real environment and vice versa in this population. METHODS: A computer program was developed comprising a motor task, but with two possibilities of user interaction: a) concrete interface (with physical contact): in which the individual touches the computer screen to finish the task and b) abstract interface (no physical contact): in which the individual performs a hand movement in front of the Kinect device. Participants were split into two groups. The experimental group consisted of 28 individuals with CP within the ages of 6 and 15 years old. The control group included 28 typically developing individuals mirroring the age and sex of the experimental group. RESULTS: Individuals from both groups were able to improve task performance and retain acquired information. The CP group presented worse performance than the control group in all phases of the study. Further findings showed that the CP group presented better performance in the abstract interface than in the concrete interface, whereas, in the control group, the opposite occurred: their best performance was in the concrete. CONCLUSIONS: Motor tasks performed by individuals with CP through an interface with a more virtual environment feature (abstract interface: Kinect) provided better performance when compared to an interface with a more real characteristic (concrete interface: Touchscreen). TRIAL REGISTRATION: ClinicalTrials.gov Identifier - NCT03352440; Date of registration - November 17, 2017.

A Cross-sectional Survey of Comprehension and Satisfaction of Spanish-Reading Adults Regarding RÁPIDO as a Stroke Awareness Acronym.

ABSTRACT: BACKGROUND: Delay time to hospital arrival may be influenced by lack of recognition of stroke signs and the necessity to seek emergency medical, which in turn is influenced by language barriers to, a modifiable risk factor, stroke awareness education. The objective was to determine the comprehension and satisfaction of a Spanish stroke awareness acronym, RÁPIDO, among community-living, Hispanic and Latino, Spanish-reading adults. METHODS: A 33-item survey was completed by 166 adults. Data on sociodemographics, language preferences, stroke education, and comprehension and satisfaction with RÁPIDO were collected. Descriptive characteristics were calculated. Fisher exact tests were performed to determine whether reading language (group 1, only or predominantly reads in Spanish; group 2, reads in Spanish and English equally or reads predominately in English) influenced survey responses. Responses to open-ended questions were categorized. RESULTS: Sixty-nine percent of the participants were born outside of the United States, 82% currently resided in the United States, 34% read only or predominately in Spanish, and 7% had a stroke. Most participants thought RÁPIDO was informative, eye-catching, and easily remembered. Significant differences were found between reading language preference groups for correctly identifying RÁPIDO images for facial drooping (group 1, 80%; group 2, 95%; P ≤ .001) and dizziness/loss of balance (group 1, 54%; group 2, 73%; P = .027). Eighty percent or more of all participants were able to correctly interpret RÁPIDO images for facial drooping, blurry vision, impaired speech, and call emergency services. Adding "911" to the RÁPIDO image of the clock was a common suggestion. CONCLUSIONS: RÁPIDO was well received among the participants. Modifications to RÁPIDO images representing dizziness/loss of balance and arm weakness, and the addition of "911" may improve its usefulness. Obtaining more extensive feedback across the United States and testing the effect of RÁPIDO on increasing knowledge of stroke signs and retention of that knowledge are necessary next steps.

Analysis of the insulin-like growth factor 1 receptor gene in children born small for gestational age: in vitro characterization of a novel mutation (p.Arg511Trp).

BACKGROUND: Insulin-like growth factor 1 insensitivity caused by IGF1R mutations has been previously identified as one of the causes of growth impairment in children born small for gestational age (SGA). OBJECTIVE: To analyse the IGF1R in children born SGA. SUBJECTS: From an initial cohort of 54 sequential children born SGA, without catch-up growth, 25 children were selected for this IGF1R study due to the presence of serum IGF-1 values above the mean for their age and sex. METHODS: The proximal IGF1R promoter region, the entire coding region and the exon-intron boundaries were directly sequenced, and multiplex ligation-dependent probe amplification analysis was performed. Fibroblast cultures were developed from one patient with a mutation for the in vitro characterization of IGF-1 insensitivity. RESULTS: The copy number variation analysis did not identify deletions involving the IGF1R gene. We identified two children carrying heterozygous nucleotide substitutions in IGF1R: c.16G>A/p.Gly6Arg and c.1531C>T/p.Arg511Trp. The first variant (p.Gly6Arg) was identified in control subjects (0·3%) and in a relative with normal growth; thus, it was considered to be a rare benign allelic variation. The second variant (p.Arg511Trp) was not found in 306 alleles from control subjects, and it segregated with the growth impairment phenotype in the patient's family. Fibroblasts obtained from this patient had a significantly reduced proliferative response and AKT phosphorylation after IGF-1 stimulation compared with control fibroblasts. CONCLUSION: The identification of an inactivating IGF1R mutation in the present cohort should encourage further studies of larger series to establish the precise frequency of this molecular defect in children with growth impairment of a prenatal onset.

A scoping review of how exposure to urban violence impacts youth access to sexual, reproductive and trauma health care in LMICs.

Violence in the community can impact access to health care. This scoping review examines the impact of urban violence upon youth (aged 15-24) access to sexual and reproductive health and trauma care in Low and Middle Income Countries (LMICs). We searched key electronic health and other databases for primary peer-reviewed studies from 2010 through June 2020. Thirty five of 6712 studies extracted met criteria for inclusion. They were diverse in terms of study objective and design but clear themes emerged. First, youth experience the environment and interpersonal relationships to be violent which impacts their access to health care. Second, sexual assault care is often inadequate, and stigma and abuse are sometimes reported in treatment settings. Third is the low rate of health seeking among youth living in a violent environment. Fourth is the paucity of literature focusing on interventions to address these issues. The scoping review suggests urban violence is a structural and systemic issue that, particularly in low-income areas in LMICs, contributes to framing the conditions for accessing health care. There is a gap in evidence about interventions that will support youth to access good quality health care in complex scenarios where violence is endemic.

Inconsistent condom use with casual partners among men who have sex with men in Brazil: a cross-sectional study.

OBJECTIVE: This study aimed to evaluate factors associated with inconsistent condom use with casual partners in a population of men who have sex with men (MSM) in Brazil. METHODS: In 2016, 4,176 MSM >18 years were enrolled in 12 capitals of Brazil using a Respondent Driven Sampling (RDS) method. For the construction of the outcome, we evaluated questions about condom use in all anal intercourse (receptive and insertive) in the previous six months and the last sexual intercourse. Estimates were calculated using a weighted complex sample design. We performed a logistic regression analysis to determine the associations between sociodemographic and behavioral factors and inconsistent condom use in sexual relationships with casual male partners. RESULTS: More than half of our sample (50.8%) had not used condoms consistently with casual partners in the previous six months. Inconsistent condom use was significantly associated with: low education (weighted odds ratio - wOR: 1.55; 95% confidence interval - CI 0.99-2.40), lack of counseling on sexually transmitted infections STI (wOR: 1.51; 95%CI 1.05-2.17), non-use of condoms at sexual debut (wOR: 3.05; 95%CI 2.12-4.40) and moderate and high perceived risk for HIV (wOR: 1.51; 95%CI 1.07-2.14). Higher age was negatively associated with inconsistent condom use (wOR=0.97, 95%CI 0.89-0.99). CONCLUSION: Despite being an individual behavior, condom use is related to factors beyond the individual scope. HIV/Aids prevention policies should focus on younger MSM, providing qualified information about condom use, preferably before the beginning of their sexual life.

Clinical and Genetic Characterization of Familial Central Precocious Puberty.

CONTEXT: Central precocious puberty (CPP) can have a familial form in approximately one-quarter of the children. The recognition of this inherited condition increased after the identification of autosomal dominant CPP with paternal transmission caused by mutations in the MKRN3 and DLK1 genes. OBJECTIVE: We aimed to characterize the inheritance and estimate the prevalence of familial CPP in a large multiethnic cohort; to compare clinical and hormonal features, as well as treatment response to GnRH analogs (GnRHa), in children with distinct modes of transmission; and to investigate the genetic basis of familial CPP. METHODS: We retrospectively studied 586 children with a diagnosis of CPP. Patients with familial CPP (n = 276) were selected for clinical and genetic analysis. Data from previous studies were grouped, encompassing sequencing of MKRN3 and DLK1 genes in 204 patients. Large-scale parallel sequencing was performed in 48 individuals from 34 families. RESULTS: The prevalence of familial CPP was estimated at 22%, with a similar frequency of maternal and paternal transmission. Pedigree analyses of families with maternal transmission suggested an autosomal dominant inheritance. Clinical and hormonal features, as well as treatment response to GnRHa, were similar among patients with different forms of transmission of familial CPP. MKRN3 loss-of-function mutations were the most prevalent cause of familial CPP, followed by DLK1 loss-of-function mutations, affecting, respectively, 22% and 4% of the studied families; both affected exclusively families with paternal transmission. Rare variants of uncertain significance were identified in CPP families with maternal transmission. CONCLUSION: We demonstrated a similar prevalence of familial CPP with maternal and paternal transmission. MKRN3 and DLK1 loss-of-function mutations were the major causes of familial CPP with paternal transmission.

An Intervention Mapping Approach to Developing a Stroke Literacy Video for Recent Stroke Survivors: Development and Usability Study.

BACKGROUND: Most vascular events after stroke may be prevented by modifying vascular risk factors through medical and behavioral interventions. Stroke literacy-an understanding of stroke symptoms, risk factors, and treatment-likely contributes to vascular risk factor control and in turn stroke recurrence risk. Stroke literacy is the lowest among adults belonging to racial and ethnic minority populations in the United States. Video-based interventions targeting stroke literacy may help acute stroke survivors understand stroke and subsequently reduce the risk of stroke recurrence. However, the failure of prior stroke literacy interventions may be due in part to the fact that the interventions were not theory-driven. Intervention mapping (IM) provides a framework for use in the development, implementation, and evaluation of evidence-informed, health-related interventions. OBJECTIVE: We aimed to develop a video-based educational intervention to improve stroke literacy in hospitalized patients with acute stroke. METHODS: The 6-step iterative process of IM was used to develop a video-based educational intervention and related implementation and evaluation plans. The six steps included a needs assessment, the identification of outcomes and change objectives, the selection of theory- and video-based intervention methods and practical applications, the development of a video-based stroke educational intervention, plans for implementation, and evaluation strategies. RESULTS: A 5-minute video-based educational intervention was developed. The IM approach led to successful intervention development by emphasizing stakeholder involvement, generation and adoption, and information retainment in the planning phase of the intervention. A planned approach to video adoption, implementation, and evaluation was also developed. CONCLUSIONS: An IM approach guided the development of a 5-minute video-based educational intervention to promote stroke literacy among acute stroke survivors. Future studies are needed to assess the use of technology and digital media to support widespread access and participation in video-based health literacy interventions for populations with acute and chronic stroke. Studies are needed to assess the impact of video-based educational interventions that are paired with stroke systems of care optimization to reduce the risk of stroke recurrence. Furthermore, studies on culturally and linguistically sensitive video-based stroke literacy interventions are needed to address known racial and ethnic disparities in stroke literacy.

[Factors associated with inconsistent condom use among men who have sex with men in Brazil and their commercial sexual partners]. / Fatores associados ao uso inconsistente de preservativo com parceiros comerciais entre homens que fazem sexo com homens no Brasil.

We aimed to analyze the factors associated with inconsistent condom use among men who have sex with men (MSM) and their commercial sexual partners in Brazil. This is a cross-sectional study with adult MSM who were recruited via respondent-driven sampling (RDS) in 12 Brazilian capitals in 2016. MSM answered a sociobehavioral questionnaire which included questions on their sexual behavior. The inconsistent use of condoms with their clientele was measured via insertive and receptive anal sex in the six months prior to our research and in their last sexual intercourse. The association between independent variables and the inconsistent use of condoms was measured via a Poisson regression model with robust variance and estimation of adjusted prevalence ratios (aPR). Data from 461 MSM were analyzed. We found a 26% prevalence of inconsistent condom use with their clientele (95%CI: 19.0-34.3, n = 123). Belonging to the lowest economic classes (D/E), having medium or low knowledge about HIV, having practiced insertive and receptive anal sex, and having never tested for HIV throughout their lives were associated with inconsistent use of condoms with their clientele. The variables associated with inconsistent use indicated that commercial sex is practiced in a context of greater vulnerability to HIV infection, referring to the need for biomedical and behavioral interventions which focus on access to and use of prevention strategies together with public policies to reduce socioeconomic inequalities among MSM who practice commercial sexual.

O objetivo foi analisar os fatores associados ao uso inconsistente de preservativo com parceiros comerciais entre homens que fazem sexo com homens (HSH) no Brasil. Foi feito um estudo transversal, com HSH adultos, recrutados por meio da técnica respondent-driven sampling (RDS), em 12 capitais brasileiras, em 2016. Os HSH responderam a um questionário sociocomportamental, que incluía questões sobre o comportamento sexual. O uso inconsistente de preservativo com parceiros comerciais foi mensurado por meio das relações sexuais anais insertivas e receptivas, ocorridas nos últimos seis meses e na última relação sexual. A associação entre as variáveis independentes e o uso inconsistente de preservativo foi mensurada utilizando o modelo de regressão de Poisson com variância robusta, com estimação de razões de prevalência ajustadas (RPa). Foram analisados dados de 461 HSH. A prevalência de uso inconsistente de preservativo com parceiros comerciais foi de 26% (IC95%: 19,0-34,3, n = 123). Pertencer às classes econômicas mais baixas (D/E), ter médio ou baixo conhecimento sobre HIV, ter praticado sexo anal insertivo e receptivo e nunca ter realizado teste para HIV na vida são fatores que estiveram associados ao uso inconsistente de preservativo com parceiros comerciais. As variáveis associadas ao uso inconsistente indicaram que o sexo comercial está sendo praticado em um contexto de maior vulnerabilidade à infecção pelo HIV. Nesse sentido, são necessárias intervenções biomédicas e comportamentais, com foco no acesso e na utilização de estratégias de prevenção, aliadas a políticas públicas para a redução de desigualdades socioeconômicas entre HSH que praticam sexo comercial.

El objetivo fue analizar los factores asociados al uso inconsistente del preservativo con las parejas comerciales entre los hombres que tienen sexo con hombres (HSH) en Brasil. Estudio transversal, con HSH adultos, reclutados a través de la técnica respondent-driven sampling (RDS), en 12 capitales brasileñas, en 2016. Los HSH respondieron a un cuestionario sociocomportamental que incluía preguntas sobre el comportamiento sexual. El uso inconsistente del preservativo con parejas comerciales se midió por las relaciones anales insertivas y receptivas que se produjeron en los últimos seis meses y por la última relación sexual. La asociación entre las variables independientes y el uso inconsistente del preservativo se midió mediante el modelo de regresión de Poisson con varianza robusta, con estimación de las razones de prevalencia ajustadas (RPa). Se analizaron los datos de 461 HSH. La prevalencia del uso inconsistente del preservativo con las parejas comerciales fue del 26% (IC95%: 19,0-34,3, n = 123). Pertenecer a las clases económicas más bajas (D/E), tener un conocimiento medio o bajo sobre el VIH, haber practicado sexo anal tanto insertivo como receptivo y no haberse sometido nunca a la prueba del VIH en su vida se asociaron con el uso inconsistente del preservativo con las parejas comerciales. Las variables asociadas al uso inconsistente indicaron que el sexo comercial se está practicando en un contexto de mayor vulnerabilidad a la infección por el VIH, refiriendo la necesidad de intervenciones biomédicas y conductuales, con un enfoque en el acceso y uso de estrategias de prevención, junto con políticas públicas para reducir las desigualdades socioeconómicas entre los HSH que practican el sexo comercial.

Telehealth effectiveness for pre-exposure prophylaxis delivery in Brazilian public services: the Combine! Study.

INTRODUCTION: Pre-exposure prophylaxis (PrEP) delivery based on user needs can enhance PrEP access and impact. We examined whether telehealth for daily oral PrEP delivery could change the indicators of care related to prophylactic use in five Brazilian public HIV clinics (testing centres, outpatient clinics and infectious disease hospitals). METHODS: Between July 2019 and December 2020, clients on PrEP for at least 6 months could transition to telehealth or stay with in-person follow-up. Clients were clinically monitored until June 2021. A desktop or mobile application was developed, comprising three asynchronous consultations and one annual in-person consultation visit. Predictors influencing telehealth preference and care outcomes were examined. The analysis encompassed intent-to-treat (first choice) and adjustments for sexual practices, schooling, age, duration of PrEP use and PrEP status during the choice period. RESULTS: Of 470 users, 52% chose telehealth, with the adjusted odds ratio (aOR) increasing over time for PrEP use (aOR for 25-months of use: 4.90; 95% CI: 1.32-18.25), having discontinued PrEP at the time of the choice (aOR: 2.91; 95% CI: 1.40-6.06) and having health insurance (aOR: 1.91; 95% CI: 1.24-2.94) and decreasing for those who reported higher-risk behaviour (aOR for unprotected anal sex: 0.51; 95% CI: 0.29-0.88). After an average follow-up period of 1.6 years (95% CI: 1.5-1.7), the risk of discontinuing PrEP (not having the medication for more than 90 days) was 34% lower with telehealth (adjusted hazard ratio: 0.66; 95% CI: 0.45-0.97). When adjusted by mixed linear regression, no differences in adherence (measured by mean medication possession rate) were found between in-person and telehealth (p = 0.486) or at pre- and post-telehealth follow-ups (p = 0.245). Sexually transmitted infections increased between the pre-follow-up and post-follow-up choices and were not associated with in-person or telehealth (p = 0.528). No HIV infections were observed. CONCLUSIONS: Our findings indicate that telehealth for PrEP delivery can enhance service rationalization and reinforce the prevention cascade. This approach reduces prophylaxis interruptions and is mainly preferred by individuals with lower demands for healthcare services.

Hepatitis B Prevalence among Men Who Have Sex with Men in Brazil.

Hepatitis B virus (HBV) is a global public health problem and requires specific prevention actions, particularly focusing on the key populations, such as men who have sex with men (MSM). We aimed at assessing the prevalence of HBV infection, among MSM, in a multicity study in Brazil. In 2016, we conducted a survey using a respondent-driven sampling methodology in 12 Brazilian cities. Rapid tests (RT) were performed on 3178 samples from those MSM. Positive results were tested for HBV DNA and sequenced. If negative for HBV DNA, samples were tested for serological markers. The prevalence rate of HBV exposure and clearance was 10.1% (95% CI: 8.1-12.6), and 1.1% (95%; CI: 0.6-2.1) were confirmed to be HBsAg-positive. Of those samples tested for anti-HBs (n = 1033), only 74.4% presented a serological profile analogous to that elicited by hepatitis B vaccination. Among HBsAg-positive samples (n = 29), 72.4% were HBV DNA-positive, and from these, 18 were sequenced. HBV genotypes A, F, and G were found in 55.5%, 38.9%, and 5.6%, respectively. This study indicates high prevalence rates of MSM HBV exposure and a low positivity index for the serological marker of HBV vaccine immunity. These findings may contribute to the discussion of strategies to prevent hepatitis B and reinforce the importance of promoting HBV vaccination in this key population.

Vulnerability and the psychosocial aspects of tooth loss in old age: a Southern Brazilian study.

Extensive tooth loss and edentulism can have a negative impact on the general health and quality of life of older adults. The extent to which psychological and social factors affect an individual's decision to undergo tooth extraction and mouth clearance (extraction of all teeth), and the theoretical relationships between social structure, social life and oral health can be unraveled through qualitative research. This study aimed to explore the social and psychological factors involved in tooth extraction and mouth clearance within a historical perspective among rural Southern Brazilian older adults. It is based on qualitative data gathered via a series of eight focus groups among 41 older adults. Underlying the focus group discussions of different levels of health risks and resources for prevention of disease was the concept of vulnerability. Participants' responses illustrated that tooth loss and mouth clearance were related to a lack of public dental health policies and programs, were influenced by social norms (including values pertaining to gender), and were associated with a low level of oral health knowledge. The social and program-dependent contexts of vulnerability were shown to have played a major role in the development of norms and values towards tooth extraction and mouth clearance. Vulnerability must be reduced in order to prevent disease particularly among rural populations. The influence of fatalistic beliefs about the inevitable loss of teeth with age may negatively influence the acceptance of dental treatment and predilection for oral health self-care.
