RESUMEN

Many countries have modified their policies on banning or deferring blood donation by men who have sex with men (MSM) in light of ethical concerns and new evidence about transfusion risks. In Brazil, MSM were not eligible to donate blood unless they had been celibate for the previous 12 months. However, in May 2020, the Brazilian Federal Supreme Court overturned this restriction. Many authors have attempted to stress possible risks of transfusion-transmitted infection under various scenarios of changes in bans or restrictions on donations by MSM using mathematical models, but we consider that it is a difficult task due to the wide variety of sexual behaviors, attitudes, and practices. Among these factors, we highlight sex under the influence of illicit drugs, and the fact that people with an undetectable human immunodeficiency virus viral load have the potential to transmit should their blood be transfused. Despite these possible risks, we believe that some MSM can donate blood regardless of the time elapsed since their last sexual contact, especially because blood donations by MSM were occurring even when there were time-based deferral rules. Blood banks should always seek to use screening algorithms to identify high-risk sexual behaviors using gender-neutral criteria, and education about transfusion risks should be offered to healthcare workers and MSM.

RESUMEN

INTRODUCTION: One of the most popular ways to meet new people in the modern world is through dating apps. However, its use may facilitate casual sexual encounters and quick partner changes, both of which associated to endangering sexual health in different populations. OBJECTIVE: To describe the use of mobile dating apps among undergraduate students at a major Brazilian public university and investigate its associations with sexual risk behaviors and sociodemographic factors. METHODS: This is a cross-sectional study based on a web survey. The link for participation was made available to students enrolled in undergraduate courses in the eight units of the University of São Paulo, Campus Ribeirão Preto. Use of dating apps, sociodemographic/behavioral profile, and sexual risk behaviors were among the variables studied. The distribution of apps users was calculated for each variable of interest, and prevalence ratios (PRs) were used for comparisons. PRs were reported with 95% confidence intervals. RESULTS: A total of 487 students participated, with 32.9% reporting using dating apps. Male participants were more likely to use. The use of dating apps was associated with having multiple sexual partners and risky behaviors such as smoking, alcohol consumption, and substance abuse. CONCLUSION: It is critical to describe the pattern of app use in undergraduate students and understand their influence on sexual health in order to avoid stigmatizing users. Additionally, this information can be helpful in directing the creation of strategies for using these apps as resources to promote health, such as the information-sharing regarding the sexual health.

RESUMEN

In Brazil, the advent of voluntary and counseling testing (VCT) has provided many benefits in the fight against AIDS. A sectional open web survey was conducted to investigate the Brazilian LGBT+ individuals' knowledge and perceptions of the existence of VCT centers and their associations with risk behavior and other variables of interest. The study instrument included questions on sociodemographic and behavioral variables, knowledge on VCT, access to and use of it, beliefs about HIV infection, test results, and risk perception. The Risk Behavior Score for HIV infection (RBS) was also used. A total of 1,630 volunteers participated in the survey, of whom 56.8% were men. Of these, 96.1% declared themselves as (MSM). Almost 50% of the participants had never heard about the existence of VCT, which was a higher knowledge score among MSM. A low frequency of participants had a clear perception of the risks to which they are exposed, whereas those with higher RBS were aware of the existence of VCT. As VCT is critical for the implementation of policies to combat and prevent HIV and other sexually transmitted diseases, our results can contribute to a better understanding of the influence of VCT on the frequency of testing, serological surveillance, and routine counseling for key populations.

Resumo No Brasil, o advento dos centros de testagem e aconselhamento (CTA) trouxe muitos benefícios na luta contra a Aids. Um estudo transversal do tipo web survey foi realizado para investigar o conhecimento e as percepções dos indivíduos LGBT+ brasileiros sobre a existência dos CTAs e suas associações com comportamentos de risco e outras variáveis de interesse. O questionário incluiu questões sociodemográficas e comportamentais, conhecimento sobre o CTA, acesso e uso, crenças sobre a infecção pelo HIV, resultados de testes e percepção de risco. O escore de comportamento de risco (RBS) também foi utilizado. Participaram 1.630 voluntários (56,8% homens). Destes, 96,1% se autodeclararam homens que fazem sexo com homens (HSH). Quase 50% dos participantes não conhecem os CTAs, sendo este conhecimento maior entre os HSHs. Uma baixa frequência de participantes tem percepção clara dos riscos a que estão expostos, e os HSHs com maior pontuação no RBS estão cientes da existência dos CTAs, que são fundamentais na implementação de políticas de combate e prevenção ao HIV e outras doenças sexualmente transmissíveis. Nossos resultados contribuem para a melhor compreensão da sua influência na frequência de testagem, na vigilância do status sorológico e no aconselhamento em populações-chave.

RESUMEN

In May 2020, after years of demands by activists and in light of COVID-19-related blood shortages, the Brazilian Federal Supreme Court abolished the rules that demanded a 12-month celibacy period for men who have sex with men (MSM) to donate blood. The objective of this open web survey was to assess the perceptions and practices regarding blood donation and blood donation rules among members of the Brazilian LGBT+ community. The data collection was conducted between October 2019 and March 2020, before the changes in the rules for blood donation and before the onset of the COVID-19 pandemic in Brazil. A total of 1639 adult individuals, self-declared as LGBT+ , participated (54.3 % MSM, 2.2 non-MSM, 43.5 % women). As expected, most of the study participants did not agree with the 12-month deferral period for MSM donate blood. Blood donation was already practiced by MSM, even before the abolition of the restrictions on donation. Among MSM and women, 38.7 % and 41.0 % have already donated blood, respectively. A significant number of participants reported lying in screening interviews at blood banks in order to be able to donate, and many said they knew people who were MSM and disobeyed the rules for donation, even though they knew them. Therefore, the practice of blood donation was already present among these people, even before the restriction policy change, confirming the need for revised rules for blood donation.

RESUMEN

BACKGROUND: We hypothesize that awareness of individuals' risk behaviors may influence aspects of attitude toward blood donation (i.e., intentions and self-efficacy). Investigating this association in the population of MSM was the objective of the present study. STUDY DESIGN AND METHODS: This is a cross-sectional study based on an open web survey. The online survey was developed and applied on the Research Electronic Data Capture (REDCap) platform. The study's information, invitation to participate, and link to access the online survey were disseminated using social media. Analyses were performed using structural equation modeling. RESULTS: A total of 764 young adults MSM participated, with the majority self-reporting as homosexual, single, in good health, and having completed higher education. A total of 297 (39.5%) reported having donated blood at least once in their lives. Among blood donors, 72.0% admitted to lying about their sexual behavior during the blood donation clinical screening interview; 81.0% did not believe that their behaviors put them at risk for HIV infection; 83.7% believed that their blood is safe enough to be transfused. Structural equation analysis provided evidence that the perception of being at risk for HIV and the perception of having non-safe blood to be transfused contributed to an attitude against future blood donation (explained variance 50%). DISCUSSION: Attitude plays an important role in blood donation decision-making by young adults MSM. This is the first study to provide evidence that the self-perceptions of being at risk for HIV and having non-safe blood may deter MSM from blood donation.

RESUMEN

BACKGROUND: Diverticulitis is an acute inflammatory process that affects individuals with diverticular disease. Given the sharp increase in the diagnostic rate of such a pathological process, there was also an increased interest in elucidating the possible causes related to the development of this clinical condition. Among the main factors investigated, diet excels, the object of study of this integrative literature review. METHODS: After searching the virtual health library and PubMed databases, five prospective cohort studies were selected that best answered the guiding question: "Is there a relationship between diet and the incidence of diverticulitis?". RESULTS: It was observed that the high intake of red meat and the low intake of dietary fiber were the most strongly associated dietary factors with the incidence of this inflammatory process. CONCLUSION: Therefore, it is evident that choosing healthy eating habits can considerably reduce the incidence of diverticulitis and, consequently, potentially more serious complications directly related to it.

RESUMO CONTEXTO: A diverticulite é um processo inflamatório agudo que afeta indivíduos com doença diverticular. Diante do acentuado aumento da taxa diagnóstica desse processo patológico, também houve o aumento do interesse em elucidar as possíveis causas relacionadas ao desenvolvimento dessa condição clínica. Entre os principais fatores investigados, destaca-se a dieta; objeto de estudo desta revisão integrativa da literatura. MÉTODOS: Após pesquisa nas bases de dados da biblioteca virtual em saúde e PubMed, foram selecionados cinco estudos de coorte prospectivos que melhor responderam à questão norteadora "Há relação entre dieta e incidência de diverticulite?". RESULTADOS E CONCLUSÃO: Observou-se que o alto consumo de carnes vermelhas e o baixo consumo de fibra alimentar são os fatores dietéticos mais fortemente associados à incidência desse processo inflamatório. Fica evidente, portanto, que a escolha de hábitos alimentares saudáveis pode reduzir consideravelmente a incidência de diverticulite e, consequentemente, de possíveis complicações mais graves diretamente relacionadas a ela.

RESUMEN

Physical inactivity and sedentary behavior are associated with poor physical and mental health. The article aims to assess the changes in the habits of the Brazilian participants engaged in physical activities in relation to their practices, due the measures of social distancing during the COVID-19 epidemic in 2020. The secondary objective was to describe their levels of anxiety and depression. The questionnaire used in this online survey included demographic information, questions about self-perceptions of the impact of the COVID-19 in the life routines and the 14-item Hospital Anxiety Depression Scale. A total of 1,613 adults completed the questionnaire between May 11 and 15, 2020. Of those, 79.4% reported that the measures to contain the epidemic had any impact on their physical activities, and many had to interrupt or decrease the frequency of their practices. Participants who felt a higher impact of quarantine on their physical activities tend to have higher prevalence of anxiety and depression symptoms. Individuals who practiced physical activities reported that social distance had a high influence on their practices. Furthermore, changes in these habits are associated with high levels of poor mental health.

RESUMEN

This is a cross-sectional study based on an open web survey with the primary objective to assess associations between the use of apps for seeking sex partners and vulnerabilities related to human immunodeficiency virus (HIV) acquisition among men who have sex with men (MSM) in Brazil. Participants were recruited to the study through ads posted in social media such as Twitter, Facebook, and WhatsApp. Consenting respondents completed a questionnaire on demographics, history of sexually transmitted infections (STIs), and risk behaviors and perceptions, including calculation of the Risk Behavior Score for HIV infection proposed by Rocha et al. Among the 859 participants, 714 (83.1%) reported they used apps for seeking sex partners. Use of apps for seeking sex partners was associated with high-risk behavior for HIV infection, self-reported syphilis, self-perception of HIV risk, and use of marijuana. The use of apps for seeking sex partners has rapidly become the norm for MSM in Brazil. The associations with STIs and risk behaviors should be seen as an opening to improve public health, presenting opportunities to promote knowledge, safer sex practices, and referral to HIV/STI screening and prevention interventions.

RESUMEN

Abstract INTRODUCTION: Acquired immunodeficiency syndrome (AIDS) remains a major public health issue in Brazil. This ecological study aimed to evaluate the spatiotemporal distribution of notified new AIDS cases in Brazil between 2012 and 2016. METHODS: A Bayesian spatiotemporal model based on the Poisson distribution was used to obtain smoothed incidence estimates of AIDS in each of the 133 Brazilian intermediate regions. RESULTS: Spatial distribution of new AIDS cases is highly heterogeneous. Regions with higher gross domestic product per capita tend to have higher incidence rates of AIDS. CONCLUSIONS: Strategies to prevent and control AIDS should consider regional differences.

RESUMEN

ABSTRACT Reevaluation of the deferral from voluntary blood donation by men who have sex with men (MSM) is being discussed in several countries, motivated by the need to ensure a blood supply free from transfusion-transmissible infections (e.g., HIV, syphilis). Policies being considered include: permanent exclusion for any male-male sexual encounter, temporary deferral (3 months, 12 months, 5 years) from the last encounter, or specifying behaviors that differentiate MSM at high risk from those at low risk. Current Brazilian regulations defer MSM from blood donation for 12-months after the last male-male sexual encounter. Broad epidemiological evidence indicates that many MSM are at increased risk for HIV in the present era, and few data exist to distinguish which men are likely to be in the immunological window for detection of these infections. A multicenter study developed in Brazil demonstrated that the history of male-male sex was the most strongly associated with being an HIV-positive blood donor. Meanwhile, the blanket deferral of MSM from blood donation has generated considerable controversy. Rejection of the deferral policies stems in part from perspectives defending human rights, promoting equality and citizenship, and alleging bias and discrimination. The objective of this report is to discuss the current situation of blood donation among MSM in Brazil. We highlight the lack of evidence for a true risk profile for male-male sex in the context of blood donation upon which to base sound policy. We recommend research to establish effective and acceptable criteria for blood donation by MSM and other blood donors.
