Resumo: Estudo transversal, de base hospitalar, nacional, com entrevista de 23.894 puérperas, em 2011-2012, com os objetivos de estimar a prevalência de consumo de álcool na gestação e identificar grupos mais vulneráveis. O uso de álcool na gestação foi identificado por meio da escala TWEAK, sendo classificadas como “diagnóstico presumível de uso inadequado de álcool” mulheres com pontuação ≥ 2. Calculou-se a prevalência nacional de uso de álcool e em subgrupos de acordo com características maternas, com respectivos intervalos de 95% de confiança (IC95%). Foram encontradas, de forma gráfica, coexistência de tabagismo, inadequação de consultas pré-natais e ingestão de bebidas alcoólicas na gestação. A prevalência de uso de álcool foi de 14% (IC95%: 13,3-14,7), com 10% (IC95%: 9,3-10,6) das mulheres apresentando diagnóstico presumível de uso inadequado de álcool na gestação. Maiores prevalências de uso de álcool e de diagnóstico presumível de uso inadequado foram observadas em mulheres pretas, com 12-19 anos de idade, com menor índice de escolaridade, de classe econômica mais baixa, sem companheiro, sem trabalho remunerado, com mais de três partos anteriores, que não queriam engravidar, com assistência pré-natal inadequada, com parto em serviços públicos e que referiram tabagismo na gestação. Estima-se que 1,2% das mulheres entrevistadas apresentavam concomitância dos três fatores de risco para desfechos perinatais negativos: fumo, álcool e assistência pré-natal inadequada. Os resultados demonstraram alta prevalência de uso de álcool na gestação e de diagnóstico presumível de uso inadequado, principalmente por mulheres em situação de vulnerabilidade social. São relevantes a elaboração de políticas públicas que contemplem ações de prevenção do uso de bebidas alcoólicas e a prestação de serviços de apoio para cessação do uso de álcool na gravidez.

Abstract We conducted a systematic review and meta-analysis of studies assessing HCV infection rates in haemodialysis patients in Brazil (Prospero CRD #42021275068). We included studies on patients under haemodialysis, comprising both convenience samples and exhaustive information from selected services. Patients underwent HCV serological testing with or without confirmation by HCV RNA PCR. Exclusion criteria were the following: absence of primary empirical information and studies without information on their respective settings, study year, accurate infection rates, or full specification of diagnostic tests. Studies with samples ≤ 30 and serial assessments with repeated information were also excluded. Reference databases included PubMed, LILACS, Scopus, and Web of Science for the period 1989–2019. A systematic review was carried out, followed by two independent meta-analyses: (i) studies with data on HCV prevalence and (ii) studies with a confirmatory PCR (i.e., active infection), respectively. A comprehensive set of different methods and procedures were used: forest plots and respective statistics, polynomial regression, meta-regression, subgroup influence, quality assessment, and trim-and-fill analysis. 29 studies and 11,290 individuals were assessed. The average time patients were in haemodialysis varied from 23.5 to 56.3 months. Prevalence of HCV infection was highly heterogeneous, with a pronounced decrease from 1992 to 2001, followed by a plateau and a slight decrease in recent years. The summary measure for HCV prevalence was 34% (95% CI 26–43%) for studies implemented before 2001. For studies implemented after 2001, the corresponding summary measure was 11% (95% CI 8–15%). Estimates for prevalence of active HCV infection were also highly heterogeneous. There was a marked decline from 1996 to 2001, followed by a plateau and a slight increase after 2010. The summary measure for active HCV infection was 19% (95% CI 15–25%) in studies carried out before 2001. For studies implemented after 2001, the corresponding summary measure was 9% (95% CI 6–13%). Heterogeneity was pervasive, but different analyses helped to identify its underlying sources. Besides the year each study was conducted, the findings differed markedly between geographic regions and were heavily influenced by the size of the studies and publication biases. Our systematic review and meta-analysis documented a substantial decline in HCV prevalence among Brazilian haemodialysis patients from 1992 to 2015. CKD should be targeted with specific interventions to prevent HCV infection, and if prevention fails, prompt diagnosis and treatment. Although the goal of HCV elimination by 2030 in Brazil remains elusive, it is necessary to adopt measures to achieve micro-elimination and to launch initiatives towards targeted interventions to curb the spread of HCV in people with CKD, among other high-risk groups. This is of particular concern in the context of a protracted COVID-19 pandemic and a major economic and political crisis.

Objetivo. Evaluar la cobertura y las desigualdades en las intervenciones de salud maternoinfantil entre haitianos, migrantes haitianos en la República Dominicana y dominicanos. Métodos. Estudio transversal con datos de encuestas representativas en el nivel nacional realizadas en Haití en el 2012 y en la República Dominicana en el 2014. Se compararon nueve indicadores: la demanda de planificación familiar satisfecha con métodos modernos, la atención prenatal, la atención del parto (por personal de salud calificado), la vacunación infantil (con vacuna con la tuberculosis, el sarampión y tres dosis de la vacuna triple bacteriana), la gestión de casos de enfermedad en la infancia (administración de sales de rehidratación oral para la diarrea y búsqueda de atención sanitaria ante la sospecha de neumonía) e índice de cobertura compuesto. La riqueza se midió mediante un índice basado en los activos, dividido en terciles, y el lugar de residencia (urbano o rural) se determinó según la definición del país. Resultados. La población haitiana mostró la menor cobertura respecto de la demanda de planificación familiar satisfecha con métodos modernos (44,2%), atención prenatal (65,3%), asistencia calificada en el parto (39,5%) y búsqueda de atención sanitaria ante la sospecha de neumonía (37,9%), y la mayor cobertura respecto de la administración de sales de rehidratación oral para la diarrea (52,9%); los migrantes haitianos presentaron la menor cobertura en DPT3 (44,1%) y la administración de sales de rehidratación oral para la diarrea (38%) y la mayor cobertura en la búsqueda de atención sanitaria ante la sospecha de neumonía (80,7%). La población dominicana presentó la cobertura más alta en la mayoría de los indicadores, excepto en la administración de sales de rehidratación oral para la diarrea y en la búsqueda de atención sanitaria ante la sospecha de neumonía. El índice de cobertura compuesto fue de 79,2% para los dominicanos, 69,0% para los migrantes haitianos y 52,6% para los haitianos. Las desigualdades socioeconómicas tuvieron, en general, un patrón a favor de los ricos y de las zonas urbanas en todos los grupos analizados. Conclusión. Los migrantes haitianos en la República Dominicana presentaron una mayor cobertura que la población haitiana residente en Haití, pero menor que la población dominicana. Ambos países deberían planificar acciones y políticas para aumentar la cobertura y abordar las desigualdades existentes en las intervenciones de salud materna.

Objective. To assess coverage and inequalities in maternal and child health interventions among Haitians, Haitian migrants in the Dominican Republic and Dominicans. Methods. Cross-sectional study using data from nationally representative surveys carried out in Haiti in 2012 and in the Dominican Republic in 2014. Nine indicators were compared: demand for family planning satisfied with modern methods, antenatal care, delivery care (skilled birth attendance), child vaccination (BCG, measles and DPT3), child case management (oral rehydration salts for diarrhea and careseeking for suspected pneumonia), and the composite coverage index. Wealth was measured through an asset-based index, divided into tertiles, and place of residence (urban or rural) was established according to the country definition. Results. Haitians showed the lowest coverage for demand for family planning satisfied with modern methods (44.2%), antenatal care (65.3%), skilled birth attendance (39.5%) and careseeking for suspected pneumonia (37.9%), and the highest for oral rehydration salts for diarrhea (52.9%), whereas Haitian migrants had the lowest coverage in DPT3 (44.1%) and oral rehydration salts for diarrhea (38%) and the highest in careseeking for suspected pneumonia (80.7%). Dominicans presented the highest coverage for most indicators, except oral rehydration salts for diarrhea and careseeking for suspected pneumonia. The composite coverage index was 79.2% for Dominicans, 69.0% for Haitian migrants, and 52.6% for Haitians. Socioeconomic inequalities generally had pro-rich and pro-urban pattern in all analyzed groups. Conclusion. Haitian migrants presented higher coverage than Haitians, but lower than Dominicans. Both countries should plan actions and policies to increase coverage and address inequalities of maternal health interventions.

Abstract Background Low molecular weight carrageenan (Cg) is a seaweed-derived sulfated polysaccharide widely used as inflammatory stimulus in preclinical studies. However, the molecular mechanisms of Cg-induced inflammation are not fully elucidated. The present study aimed to investigate the molecular basis involved in Cg-induced macrophages activation and cytokines production. Methods Primary culture of mouse peritoneal macrophages were stimulated with Kappa Cg. The supernatant and cell lysate were used for ELISA, western blotting, immunofluorescence. Cg-induced mouse colitis was also developed. Results Here we show that Cg activates peritoneal macrophages to produce pro-inflammatory cytokines such as TNF and IL-1β. While Cg-induced TNF production/secretion depends on TLR4/MyD88 signaling, the production of pro-IL-1β relies on TLR4/TRIF/SYK/reactive oxygen species (ROS) signaling pathway. The maturation of pro-IL1β into IL-1β is dependent on canonical NLRP3 inflammasome activation via Pannexin-1/P2X7/K+ efflux signaling. In vivo, Cg-induced colitis was reduced in mice in the absence of NLRP3 inflammasome components. Conclusions In conclusion, we unravel a critical role of the NLRP3 inflammasome in Cg-induced pro-inflammatory cytokines production and colitis, which is an important discovery on the pro-inflammatory properties of this sulfated polysaccharide for pre-clinical studies. Video abstract Graphical Abstract Carrageenan (Cg) is one the most used flogistic stimulus in preclinical studies. Nevertheless, the molecular basis of Cg-induced inflammation is not totally elucidated. Herein, Lopes et al. unraveled the molecular basis for Cg-induced macrophages production of biological active IL-1β. The Cg-stimulated macrophages produces pro-IL-1β depends on TLR4/TRIF/Syk/ROS, whereas its processing into mature IL-1β is dependent on the canonical NLRP3 inflammasome.

Background Cervical cancer (CC) is the fourth leading cause of death from neoplasms in women and is caused by the human papilloma virus (HPV). Several methods have been developed for the screening of cervical lesions and HPV; however, some socio-cultural factors prevent women from undergoing gynecological inspection, which results in a higher risk of mortality from cervical cancer in certain population groups as indigenous communities. This study aimed to compare the concordance in HPV detection from urine and cervical samples, to propose an alternative to cervical scraping, which is commonly used in the cervical cancer screening. Methodology The DNA from cervical scrapings and urine samples was extracted using the proteinase K method followed by precipitation with alcohol, phenol andchloroform; a modification of the proteinase K method was developed in the management of urine sediment. Viral genotyping was performed using INNOLipa. Results The study population consisted of 108 patients from an indigenous population at southern Mexico, 32 without squamous intraepithelial lesions (NSIL) and 76 with low squamous intraepithelial lesions (LSIL). The majority of NSIL cervical scrapes were negative for HPV (90.63%), whereas more than half of LSIL cases were high-risk HPV positive (51.32%), followed by multiple infection by HR-HPV (17.11%), and multiple infection by LR- and HR-HPV (9.21%). No statistically significant relationship between the cytological diagnosis and the HPV genotypes detected in the urine samples was observed. A concordance of 68.27% for HPV positivity from urine and cervical samples was observed. Similarly, a concordance of 64.52% was observed in the grouping of HPVs by oncogenic risk. HR-HPV was detected in 71% of the urine samples from women with LSIL diagnosis, which suggests that HR-HPV detected in a urine sample could indicate the presence or risk of developing SIL. Conclusion HR-HPV detection in urine samples could be an initial approach for women at risk of developing LSIL and who, for cultural reasons, refuse to undergo a gynecological inspection.

Resumo: Estimativas de mulheres que fizeram aborto provocado em localidades cujas leis são restritivas ainda são escassas na literatura científica, e a não coincidência de estimativas oriundas dos métodos hoje em uso clama pela aplicação de métodos inovadores, como novos métodos indiretos. Tal necessidade é especialmente aguda nas áreas mais densamente povoadas, como as capitais brasileiras, dada a magnitude do fenômeno e os danos e riscos daí decorrentes. O artigo objetiva estimar o número de mulheres que fez aborto provocado no Município do Rio de Janeiro, Brasil, em 2011, por meio de um modelo hierárquico bayesiano. Ele foi aplicado aos dados de um inquérito domiciliar que subsidiou a utilização do método network scale-up, no Município do Rio de Janeiro, um modelo hierárquico bayesiano utilizando as informações indiretas baseadas na rede de contatos dos participantes selecionados de forma aleatória da população. Das 1.758.145 mulheres de 15-49 anos residentes no Município do Rio de Janeiro (13.025; ICr95%: 10.635; 15.748) mulheres fizeram aborto provocado em 2011, resultando numa incidência acumulada média de 7,41 (ICr95%: 6,05; 8,96) para cada 1.000 mulheres de 15-49 anos. O estudo de autovalidação do modelo permitiu identificar padrões de subestimação em subpopulações estigmatizadas com baixa visibilidade social, como mulheres fizeram aborto provocado. O abortamento provocado é uma prática recorrente entre as mulheres no Município do Rio de Janeiro. Novos métodos de estimação indireta podem contribuir para a apreensão mais precisa do evento, considerando o contexto de ilegalidade, e contribuir para formulação de políticas de saúde.

Metabolic reprogramming is considered one of the hallmarks in cancer and is characterized by increased glycolysis and lactate production, even in the presence of oxygen, which leads the cancer cells to a process called “aerobic glycolysis” or “Warburg effect”. The E6 and E7 oncoproteins of human papillomavirus 16 (HPV 16) favor the Warburg effect through their interaction with a molecule that regulates cellular metabolism, such as p53, retinoblastoma protein (pRb), c-Myc, and hypoxia inducible factor 1α (HIF-1α). Besides, the impact of the E6 and E7 variants of HPV 16 on metabolic reprogramming through proteins such as HIF-1α may be related to their oncogenicity by favoring cellular metabolism modifications to satisfy the energy demands necessary for viral persistence and cancer development. This review will discuss the role of HPV 16 E6 and E7 variants in metabolic reprogramming and their contribution to developing and preserving the malignant phenotype of cancers associated with HPV 16 infection.

Abstract: Despite substantial improvement in prognosis and quality of life among people living with HIV/AIDS (PLWHA) in Brazil, inequalities in access to treatment remain. We assessed the impact of these inequalities on survival in Rio de Janeiro over a 12-year period (2000/11). Data were merged from four databases that comprise the national AIDS monitoring system: SINAN-AIDS (Brazilian Information System for Notificable Diseases; AIDS cases), SISCEL (laboratory tests), SICLOM (electronic dispensing system), and SIM (Brazilian Mortality Information System), using probabilistic linkage. Cox regressions were fitted to assess the impact of HAART (highly active antiretroviral therapy) on AIDS-related mortality among men who have sex with men (MSM), people who inject drugs (PWID), and heterosexuals diagnosed with AIDS, between 2000 and 2011, in the city of Rio de Janeiro, RJ, Brazil. Among 15,420 cases, 60.7% were heterosexuals, 36.1% MSM and 3.2% PWID. There were 2,807 (18.2%) deaths and the median survival time was 6.29. HAART and CD4+ > 200 at baseline were associated with important protective effects. Non-whites had a 33% higher risk of dying in consequence of AIDS than whites. PWID had a 56% higher risk and MSM a 11% lower risk of dying of AIDS than heterosexuals. Non-white individuals, those with less than eight years of formal education, and PWID, were more likely to die of AIDS and less likely to receive HAART. Important inequalities persist in access to treatment, resulting in disparate impacts on mortality among exposure categories. Despite these persistent disparities, mortality decreased significantly during the period for all categories under analysis, and the overall positive impact of HAART on survival has been dramatic.

The trend towards decline and stabilization of the AIDS epidemic in Brazil should be analyzed carefully, since aggregate data can mask regional or local inequalities in such a large and diverse country. The current study reevaluates the epidemic’s spatial dissemination and the AIDS-related mortality pattern in Brazil. The study considered all AIDS cases diagnosed in individuals over 18 years of age and living in Brazil, as well as AIDS deaths recorded in 1998-2008. Three-year moving average rates were estimated, and a spatial analysis was conducted using a local empirical Bayesian method. The epidemic was only found to be expanding in the North and Northeast regions, while declining in the rest of the country, especially in the Southeast. According to the findings, the apparent stabilization of AIDS mortality tends to mask regional disparities. Social determinants of health and regional disparities should be taken into account in program development and policymaking.

Os achados provêm de um estudo transversal de 5.981 estudantes de escolas públicas de Minas Gerais, Brasil. Avaliou-se a influência do uso de drogas sobre as práticas sexuais. Dos rapazes com relacionamento casual que referiram ter utilizado drogas ilícitas, 55,7% disseram usar preservativos de forma consistente (em todas as relações sexuais), enquanto entre os que nunca fizeram uso de tais substâncias, esse percentual foi de 65,4%. Entre os rapazes com relacionamento fixo, que utilizaram droga ilícita, o uso consistente de preservativos foi referido por 42,7%, ao passo que, para os que nunca fizeram uso dessas substâncias, esse percentual foi de 64,1%. No subgrupo dos rapazes com parceria fixa que nunca utilizaram drogas ilícitas, o uso consistente do preservativo foi menos freqüente entre os que utilizaram cigarro e/ou álcool do que entre os que não referiram este uso (60,7% vs. 71,1%). As moças apresentaram menor proporção de uso consistente do preservativo do que os rapazes, independentemente do tipo de parceria, sem influência aparente dos padrões de consumo. Os achados sugerem a necessidade de integrar a prevenção do uso de drogas à de infecções sexualmente transmissíveis/gravidez indesejada.This article summarizes the findings of a survey including 5,981 students from public schools in Minas Gerais State, Brazil. The analysis assessed the influence of drug use on sexual practices. Among the boys engaged in relationships with casual partners who stated having used illicit drugs, 55.7% reported consistent condom use, as compared to 65.4% among those not reporting such habits. Among boys engaged in relationships with stable partners who reported illicit drug use, consistent condom use was reported by 42.7%, versus 64.1% among those not reporting such habits. In the subgroup of boys engaged in stable relationships who did not report illicit drug use, consistent condom use was less frequent among those that used alcohol/cigarettes, compared to those who did not drink or smoke (60.7% vs. 71.1%). Girls were less likely than boys to use condoms consistently, regardless of the nature of their relationships, without a noticeable influence of drug use. Policies to prevent drug abuse, sexually transmitted diseases, and unplanned pregnancy should be fully integrated.

Nos últimos anos observa-se uma ênfase numa suposta associação entre a epidemia de AIDS e a "população negra" no Brasil. Após proceder uma análise do banco de dados sobre a ocorrência de HIV/AIDS no Brasil, o presente estudo examina o contexto sóciopolítico envolvido na definição de políticas públicas de recorte racial no campo da saúde. Argumentamos que questões ligadas à qualidade dos dados, à estruturação do sistema de informação e ao uso e interpretação das informações são elementos essenciais na compreensão do processo em curso. Especificamente, procuramos mostrar que os dados epidemiológicos disponíveis não são suficientes para sustentar a interpretação de que existe uma associação específica entre "população negra" e AIDS no país. Salientamos que a ênfase nessa suposta associação faz parte de uma dinâmica relacionada à construção do campo da "saúde da população negra" em anos recentes, que se vincula a processos mais amplos de inter-relação entre ativismo político e relação com o Estado, que transcendem a área da saúde.Over the last few years we have observed a growing emphasis on a supposed relationship between the AIDS epidemic and the "black population" in Brazil. After undertaking an analysis of the national data base of HIV/AIDS in Brazil, this study examines the sociopolitical context in which public policy with a focus on "race" has been defined. We argue that questions related to the quality of the data, the structuring of the information system itself and the use and interpretation of this information are all essential elements for understanding the process underway. Specifically we aim to show that the available epidemiological data are not sufficient to warrant the interpretation that there is in fact a relationship between the "black population" and AIDS in the country. We stress that the emphasis on this supposed association is part of a more general process of construction of the field of the "health of the black population" in recent years and that this is related to interrelationships between political activism and the State which go far beyond the field of health.

The HIV/AIDS epidemic among injection drug users (IDUs) in Brazil has been unique in terms of temporal and geographical contrasts. This analysis explores these contrasts through the use of multilevel modeling. Standardized AIDS incidence rates among IDUs for Brazilian municipalities (1986-2000) were used as the dependent variable, with a set of social indicators as independent variables (covariates). In some States of the North/Northeast, the epidemic among IDUs has been incipient. The São Paulo epidemic extended to reach a network of municipalities, most of which located far from the capital. More recently, on a smaller scale, a similar extension has been observed in the southernmost States of the country. Both "number of physicians per inhabitant" and "standard distance to the State capital" were found to be associated with AIDS incidence. AIDS cases among IDUs appeared to cluster in wealthier, more developed municipalities. The relative weight of such extensive dissemination in key, heavily populated States prevails in the Brazilian IDU epidemic, defining a central-western-southeastern strip of wealthier middle-sized municipalities and more recently a southern strip of municipalities deeply affected by the epidemic in this population.

Brazil provides free antiretroviral (ARV) therapy to some 150,000 individuals living with HIV/ AIDS). ARV regimens require optimal adherence to achieve undetectable viral loads and to avoid viral resistance. Physicians play a key role to foster ARV adherence, but until now little is known about the communication between physicians/ people living with HIV/AIDS in this setting. In-depth interviews were conducted with 40 physicians treating people living with HIV/AIDS at six public reference centers in Rio de Janeiro, Brazil. Interview topics included: experiences in the treatment of people living with HIV/AIDS, relationship and dialogue with patients, barriers/facilitators to adherence, and effectiveness of available services. Barriers to ARV adherence were mainly related to the low quality of patient-provider relationship. Other barriers were related to "chaotic" patients' lifestyles, and inadequate knowledge and/or negative beliefs about HIV/AIDS and ARV effectiveness. It is necessary to improve networking between services, establish agile referral systems, and improve health professionals' integration. These structural changes could contribute to improved adherence, resulting in improved quality of life for people living with HIV/AIDS.O Brasil fornece gratuitamente terapia anti-retroviral (ARV) para cerca de 150 mil pessoas vivendo com HIV/ AIDS. A terapia ARV requer aderência ótima, visando alcançar carga viral indetectável e evitar resistência viral. Os médicos desempenham papel central quanto à aderência à ARV, mas há escassa informação sobre a comunicação entre médicos/pessoas vivendo com HIV/ AIDS. Entrevistas em profundidade foram realizadas com 40 médicos assistentes de seis hospitais de referência do Rio de Janeiro, Brasil. Tópicos da entrevista incluíram: experiências relativas ao tratamento de pessoas vivendo com HIV/AIDS, relacionamento/diálogo com pacientes, barreiras/facilitadores para aderência aos serviços disponíveis e eficácia destes. As barreiras para aderência à ARV se referiam, principalmente, ao relacionamento médico-paciente. Outras barreiras estavam relacionadas a estilos de vida "caóticos" de alguns pacientes, conhecimento inadequado/crenças negativas sobre HIV/AIDS e a eficácia da ARV. É necessário melhorar as redes de serviços de saúde, com encaminhamento mais ágil e maior integração entre diferentes profissionais de saúde. Essas mudanças estruturais podem melhorar a aderência e a qualidade de vida das pessoas vivendo com HIV/AIDS.

The complex dynamical analysis of the parametric fourth-order Kim’s iterative family is made on quadratic polynomials, showing the MATLAB codes generated to draw the fractal images necessary to complete the study. The parameter spaces associated with the free critical points have been analyzed, showing the stable (and unstable) regions where the selection of the parameter will provide us the excellent schemes (or dreadful ones).

A review was carried out of papers published between 1996 and 2006, documenting the introduction of highly active anti-retroviral therapy (HAART) in Brazil. Papers indexed in the MEDLINE and SciELO databases were retrieved using different combinations of keywords related to the management and care of AIDS in the post-HAART era: opportunistic diseases and co-infections, adherence to therapy, survival in the pre- and post-HAART eras, adverse events and side-effects, emergence and possible transmission of resistant viral strains, metabolic and cardiovascular disorders, and issues related to access to care and equity. The review documents the dramatic changes in HIV/AIDS disease progression in the post-HAART era, including an increase in survival and quality of life and a pronounced decrease in the episodes of opportunistic diseases. Notwithstanding such major achievements, new challenges have emerged, including slow evolving co-infections (such as hepatitis C, metabolic and cardiovascular disorders), the emergence of viral resistance, with consequences at the individual level (virological failure) and the community level (primary/secondary resistance at the population level), and impacts on the cost of new therapeutic regimens.Procedeu-se a uma revisão abrangente de artigos publicados entre 1996-2006, período posterior à introdução da terapia anti-retroviral de alta potência (HAART) no Brasil. Foram revisados artigos disponíveis nas bases de dados MEDLINE e SciELO, a partir de combinações de palavras-chave que contemplam os principais temas na área do tratamento e manejo da AIDS na era pós-HAART: doenças oportunistas e co-infecções, aderência à terapia, sobrevida pré e pós-HAART, eventos adversos e efeitos colaterais, emergência e eventual transmissão de cepas virais resistentes e complicações cardiovasculares e metabólicas, além de questões relativas ao acesso e à eqüidade. Em suma, observa-se uma transformação profunda no campo da AIDS no período pós-HAART, com aumento dramático da sobrevida e da qualidade de vida, e redução expressiva dos episódios de doenças oportunistas. Por outro lado, novas questões se colocam, como a relevância das co-infecções de evolução lenta, como a hepatite C, os distúrbios metabólicos e cardiovasculares, e o desafio posto pela emergência de cepas resistentes, com repercussões individuais (falha virológica) e coletivas (resistência primária e secundária em nível da comunidade) e, conseqüente, aumento de custos da terapia.

Highly active antiretroviral therapy (HAART) has led to a substantial increase in the survival of people living with AIDS, despite heterogeneities among individuals from different socioeconomic strata. The present paper analyzes AIDS deaths in Brazil during a period in which HAART became a key treatment regimen, exploring the hypothesis that "race or color" defines one dimension of socioeconomic inequality in Brazil. AIDS mortality, stratified by gender and "race or color", was calculated using data from the National Mortality System. The rates were highest among individuals classified as "black" and lower among those classified as "mixed-race", with a continuous increase among the later from 1999 to 2004 for men and women. Among individuals classified as "white", mortality rates remained stable among men, but not women. Median age at death among "mixed-race" individuals was lower for both men and women. Differential trends according to gender and "race or color" were highlighted by the present study, indicating the pressing need to further explore the underlying factors that might explain different mortality rates in a context of universal access.A terapia anti-retroviral de alta potência (HAART) tem determinando substancial aumento da sobrevida de pessoas vivendo com AIDS, ainda que de forma heterogênea entre populações de diferentes condições sociais e econômicas. Este estudo analisa a mortalidade por AIDS no Brasil, num período em que a HAART se consolida como estratégia terapêutica, explorando a hipótese da variável "raça/cor" constituir uma das vertentes das desigualdades sociais e econômicas no Brasil. Foram calculadas taxas de mortalidade por AIDS, por sexo e "raça/cor", utilizando-se dados do Sistema de Informações sobre Mortalidade. As maiores taxas de mortalidade foram observadas nos indivíduos de "raça/cor" preta e as menores naqueles de "raça/cor" parda, ainda que com crescimento persistente no período observado (1999-2004), em ambos os sexos. Entre os indivíduos de "raça/cor" branca, observou-se estabilidade na taxa de mortalidade apenas entre os homens. A idade mediana dos óbitos na "raça/cor" parda foi invariavelmente mais baixa, para ambos os sexos. Tendências diferenciadas por sexo e "raça/cor" foram observadas, exigindo estudos adicionais que explorem os fatores que determinam diferenciais nas taxas de mortalidade num contexto de acesso universal.

The Brazilian AIDS epidemic is undergoing important changes in its third decade. The present article reviews some central findings: the proportional reduction in cases related to injection drug use; the stability, in recent years, of new cases in the male homosexual/bisexual population; and the relative and absolute increment in heterosexual transmission, even though the estimates of incident rates still point to the first two categories mentioned as those most affected by the epidemic. Still should be detached the persistent increase in incidence rates among women and its stability in the younger age groups, probably the result of behavior changes (such as the consistent use among youth of condoms in sexual relations with casual partners and a reduction in cases related to injection drug use). It is well-know that HIV prevalence in the general population has stabilized at less than 1%, which characterizes Brazil as one of the countries with a concentrated epidemic. The article also emphasizes the growth of AIDS morbidity-mortality in the less favored socioeconomic strata and in women, and the stability of the mortality rate among men.A epidemia de AIDS no Brasil vem experimentando na sua terceira década importantes mudanças. O presente artigo revê alguns achados centrais: a redução proporcional dos casos devido ao uso de drogas injetáveis, a estabilidade, em anos recentes, quanto aos casos novos referentes à categoria de exposição homo/bissexual masculina e o incremento, relativo e absoluto, da transmissão heterossexual, ainda que estimativas das taxas de incidência sigam apontando as duas primeiras categorias como aquelas mais afetadas pela epidemia. Destaca-se, ainda, o persistente aumento das taxas de incidência entre as mulheres e sua estabilidade nas faixas etárias mais jovens, provavelmente, em decorrência de mudanças comportamentais (como o uso consistente de preservativos nas relações sexuais com parceiros eventuais entre os mais jovens e a redução dos casos devido ao uso de drogas injetáveis). É notória a estabilidade da prevalência do HIV abaixo de 1% na população geral, o que define o Brasil como um dos países com uma epidemia concentrada. O artigo destaca ainda o crescimento da morbi-mortalidade por AIDS nas populações sócio-economicamente menos favorecidas e entre as mulheres, e a estabilidade da mortalidade por AIDS entre os homens.

The present study aims to evaluate the current operation of Brazilian syringe exchange programs (SEP). After consulting national and regional networks of people working in projects/ programs aiming to reduce drug-related harm, we identified 134 potential participant programs. Unfortunately, only 45 SEPs answered a survey, even after repeated attempts. The survey addressed: coverage, funding, procurement of basic supplies, managerial capacity, and the local political environment. Findings were triangulated with in-depth interviews with key informants. The main findings included: satisfactory adherence to the initiatives and adequate documentation, but deficiencies in terms of coverage and monitoring, and uneven procurement of resources. Program personnel work mostly on a provisional basis, despite the efforts of local coordinators. Most programs are funded by the National STDs/AIDS Program. A comprehensive agenda aiming to improve current operations should include: concerted efforts to improve local and regional databanks, incentives/sanctions toward full accountability of initiatives carried by the programs, and a genuine culture of monitoring and evaluation.

The context of first drug injection and its association with ongoing injecting practices and HCV (hepatitis C virus) infection were investigated. Injection drug users (IDUs) (N = 606) were recruited in "drug scenes" (public places, bars) in Rio de Janeiro, Brazil, interviewed, and tested for HCV. Sharing of needles/syringes was more prevalent at the first injection (51.3%) than at the baseline interview (36.8%). Those who shared syringes/needles at first injection were more likely to be currently engaged in direct/indirect sharing practices. Among young injectors (< 30 years), those reporting sharing of needles/ syringes at the first injection were about four times more likely to have been infected by HCV. Hepatitis C virus prevalence among active IDUs (n = 272) was 11%. Prison history and longer duration of drug injection were identified as independent predictors of HCV infection. To effectively curb HCV transmission among IDUs and minimize harms associated with risk behaviors, preventive strategies should target individuals initiating drug injection beginning with their very first injection and discourage the transition from non-injecting use to the self-injection of illicit drugs.

The context of first drug injection and its association with ongoing injecting practices and HCV (hepatitis C virus) infection were investigated. Injection drug users (IDUs) (N = 606) were recruited in "drug scenes" (public places, bars) in Rio de Janeiro, Brazil, interviewed, and tested for HCV. Sharing of needles/syringes was more prevalent at the first injection (51.3%) than at the baseline interview (36.8%). Those who shared syringes/needles at first injection were more likely to be currently engaged in direct/indirect sharing practices. Among young injectors (< 30 years), those reporting sharing of needles/ syringes at the first injection were about four times more likely to have been infected by HCV. Hepatitis C virus prevalence among active IDUs (n = 272) was 11%. Prison history and longer duration of drug injection were identified as independent predictors of HCV infection. To effectively curb HCV transmission among IDUs and minimize harms associated with risk behaviors, preventive strategies should target individuals initiating drug injection beginning with their very first injection and discourage the transition from non-injecting use to the self-injection of illicit drugs.

This study assessed 1,144 Brazilian injecting drug users (IDUs) recruited on the street through outreach syringe exchange programs by two multi-center cross-sectional studies: 287 IDUs were recruited during the AjUDE-Brasil I Project and 857 during the AjUDE-Brasil II Project. IDU characteristics related to drug use and sexual behavior, and legal and health conditions for the two studies were compared, using decision tree and logistic regression for each individual study, with HIV infection as the outcome. Fifty-two percent of IDUs were HIV-infected in AjUDE I versus 36.5% in AjUDE II. In both studies, HIV infection was independently associated with: mean background HIV prevalence for each site (OR = 2.17; 10.66), HCV seropositive status (OR = 19.79; 15.48), and men who reported ever having sex with other men (OR = 2.10; 2.09). Incarceration (OR = 1.41) and 8 or more years of injecting drug (OR = 2.13) were also associated with HIV in AjUDE II. The high HIV infection rates and high prevalence of both parenteral and sexual risk behaviors in the context of syringe-exchange programs are of great concern and demand thorough surveillance and renewed prevention strategies.

The present study aims to evaluate the current operation of Brazilian syringe exchange programs (SEP). After consulting national and regional networks of people working in projects/ programs aiming to reduce drug-related harm, we identified 134 potential participant programs. Unfortunately, only 45 SEPs answered a survey, even after repeated attempts. The survey addressed: coverage, funding, procurement of basic supplies, managerial capacity, and the local political environment. Findings were triangulated with in-depth interviews with key informants. The main findings included: satisfactory adherence to the initiatives and adequate documentation, but deficiencies in terms of coverage and monitoring, and uneven procurement of resources. Program personnel work mostly on a provisional basis, despite the efforts of local coordinators. Most programs are funded by the National STDs/AIDS Program. A comprehensive agenda aiming to improve current operations should include: concerted efforts to improve local and regional databanks, incentives/sanctions toward full accountability of initiatives carried by the programs, and a genuine culture of monitoring and evaluation.

Nos últimos anos observa-se uma ênfase numa suposta associação entre a epidemia de AIDS e a "população negra" no Brasil. Após proceder uma análise do banco de dados sobre a ocorrência de HIV/AIDS no Brasil, o presente estudo examina o contexto sóciopolítico envolvido na definição de políticas públicas de recorte racial no campo da saúde. Argumentamos que questões ligadas à qualidade dos dados, à estruturação do sistema de informação e ao uso e interpretação das informações são elementos essenciais na compreensão do processo em curso. Especificamente, procuramos mostrar que os dados epidemiológicos disponíveis não são suficientes para sustentar a interpretação de que existe uma associação específica entre "população negra" e AIDS no país. Salientamos que a ênfase nessa suposta associação faz parte de uma dinâmica relacionada à construção do campo da "saúde da população negra" em anos recentes, que se vincula a processos mais amplos de inter-relação entre ativismo político e relação com o Estado, que transcendem a área da saúde.
