In 1994 Brazil launched what has since become the world’s largest community-based primary health care program. Under the Family Health Program, teams consisting of at least one physician, one nurse, a medical assistant, and four to six trained community health agents deliver most of their services at community-based clinics. They also make regular home visits and conduct neighborhood health promotion activities. This study finds that during 1999–2007, hospitalizations in Brazil for ambulatory care–sensitive chronic diseases, including cardiovascular disease, stroke, and asthma, fell at a rate that was statistically significant and almost twice the rate of decline in hospitalizations for all other causes. In municipalities with high Family Health Program enrollment, chronic disease hospitalization rates were 13 percent lower than in municipalities with low enrollment, when other factors were held constant. These results suggest that the Family Health Program has improved health system performance in Brazil by reducing the number of potentially avoidable hospitalizations.

The city of Salvador has the highest prevalence of HTLV-I among blood donors in Brazil. To study the prevalence of HTLV-I among the general population of Salvador, 30 “sentinel surveillance areas” were selected for the investigation of various infectious diseases, and 1385 individuals within these areas were surveyed according to a simple random sample procedure. ELISA was used to screen plasma samples for antibodies to HTLV-I, and the positive samples were tested by a confirmatory assay (Western blotting). The overall prevalence of HTLV-I was 1.76% (23/1385). Infection rates were 1.2% for males and 2.0% for females. Specific prevalence demonstrated an increasing linear trend with age. No one younger than 13 years of age was infected. Multivariate analysis estimated adjusted odds ratios for the association of HTLV-I with age of 9.7 (3.3; 30.4) for females and 12.3 (1.47; 103.1) for males. Less education and income might be associated with HTLV-I infection in females. Phylogenetic analysis of the long terminal repeat fragments showed that most of the samples belonged to the Latin American cluster of the Transcontinental subgroup (Cosmopolitan subtype). For the entire city of Salvador, it is estimated that ∼40,000 individuals are infected with HTLV-I. Our results suggest multiple post-Colombian introductions of African HTLV-Ia strains in Salvador.
To conduct the first national biological and behavioral surveillance survey for HIV among MSM in Brazil. A cross-sectional surveillance study utilizing Respondent Driven Sampling (RDS) in 10 cities, following formative research. Planned sample: 350 MSM reporting sex with another man in the last 12 months, at least 18 years of age, and residing in the city of the study. Conventional RDS recruitment. Results were calculated for each city using RDSAT 5.6. For the national estimate, a new individual weight using a novel method was calculated. The 10 cities were aggregated, treated as strata and analyzed using STATA11.0. Self-reported HIV status and logistic regression was used to impute missing values for serostatus, an important issue for RDSAT. A total of 3859 MSM were interviewed. Sample was diverse, most self-identified as mulatto or black, were social class C or below, and had relatively low levels of education. More than 80% reported more than one partner in the last 6 months. Only 49% had ever tested for HIV. HIV prevalence among MSM ranged from 5.2 to 23.7% in the 10 cities (3.7-16.5% without imputation) and was 14.2% for all cities combined with imputation. The overall prevalence was two and three times higher than that estimated for female sex workers and drug users, respectively, in Brazil. Half of those who tested HIV positive were not aware of their infection. The AIDS epidemic in Brazil is disproportionately concentrated among MSM, as has been found in other countries. Renewed efforts to encourage testing, prevention and treatment are required.
Resumo: A prevalência de HIV entre mulheres transgênero é desproporcional quando comparamos com a população geral em vários países. O estigma e a discriminação, por conta da identidade de gênero, têm sido comumente associados à vulnerabilidade ao HIV/aids. O objetivo foi realizar uma revisão sistemática da literatura para analisar a relação entre o estigma e a discriminação relacionados à identidade de gênero de mulheres transgênero e à vulnerabilidade ao HIV/aids. Revisão sistemática da literatura, que envolveu as etapas de identificação, fichamento, análise e interpretação de resultados de estudos valendo-se da seleção em cinco bases: PubMed, Scopus, Web of Science, Science Direct e LILACS. Não houve estabelecimento de período de tempo a priori para essa revisão. Os estudos foram avaliados de acordo com critérios de inclusão e exclusão. Foram incluídos artigos em inglês, português ou espanhol, que relacionavam o estigma e a discriminação com a vulnerabilidade de mulheres transgênero ao HIV. Foram encontrados 41 artigos, majoritariamente qualitativos, publicados no período entre 2004 e 2018, e categorizados em três dimensões do estigma: nível individual, interpessoal e estrutural. Os dados permitem destacar que os efeitos do estigma relacionado à identidade de gênero, como a violência, a discriminação e a transfobia, são elementos estruturantes no processo da vulnerabilidade da população de mulheres transgênero ao HIV/aids. Os trabalhos mostraram relação entre estigma e discriminação com a vulnerabilidade de mulheres transgênero ao HIV/aids e apontaram para a necessidade de políticas públicas que combatam a discriminação na sociedade.

Introduction: This article seeks to identify where delays occur along the adult HIV care cascade (“the cascade”), to improve understanding of what constitutes “delay” at each stage of the cascade and how this can be measured across a range of settings and to inform service delivery efforts. Current metrics are reviewed, measures informed by global guidelines are suggested and areas for further clarification are underscored.Discussion: Questions remain on how best to evaluate late entry into each stage of the cascade. The delayed uptake of HIV testing may be more consistently measured once rapid CD4 testing is administered at the time of HIV testing. For late enrolment, preliminary research has begun to determine how different time intervals for linking to HIV care affect individual health. Regarding treatment, since 2013, the World Health Organization (WHO) and UNAIDS recommend treatment initiation when CD4 <500 cells/mm3; these guidelines provide a useful albeit evolving threshold to define late treatment initiation. Finally, WHO guidelines for high‐, low‐ and middle‐income countries also could be used to standardize measures for achieving viral suppression.Conclusions: There is no “one size fits all” model as the provision of services may differ based on a range of factors. Nonetheless, measures informed by global guidelines are needed to more consistently evaluate the scope of and factors associated with delays to each stage of the cascade. Doing so will help identify how practitioners can best deliver services and facilitate access to and continued engagement in care.
