Comprehensive approach to HIV/AIDS testing and linkage to treatment among men who have sex with men in Curitiba, Brazil.

INTRODUCTION: The Curitiba (Brazil)-based Project, A Hora é Agora (AHA), evaluated a comprehensive HIV control strategy among men who have sex with men (MSM) aimed at expanding access to HIV rapid testing and linking HIV-positive MSM to health services and treatment. AHA's approach included rapid HIV Testing Services (HTC) in one mobile testing unit (MTU); a local, gay-led, non-governmental organization (NGO); an existing government-run health facility (COA); and Internet-based HIV self-testing. The objectives of the paper were to compare a) number of MSM tested in each strategy, its positivity and linkage; b) social, demographic and behavioral characteristics of MSM accessing the different HTC and linkage services; and c) the costs of the individual strategies to diagnose and link MSM to services. METHODS: We used data for 2,681 MSM tested at COA, MTU and NGO from March 2015 to March 2017. This is a cross sectional comparison of the demographics and behavioral factors (age group, race/ethnicity, education, sexually transmitted diseases, knowledge of AHA services and previous HIV test). Absolute frequencies, percentage distributions and confidence intervals for the percentages were used, as well as unilateral statistical tests. RESULTS AND DISCUSSION: AHA performed 2,681 HIV tests among MSM across three in-person strategies: MTU, NGO, and COA; and distributed 4,752 HIV oral fluid tests through the self-testing platform. MTU, NGO and COA reported 365 (13.6%) HIV positive diagnoses among MSM, including 28 users with previous HIV diagnosis or on antiretroviral treatment for HIV. Of these, 89% of MSM were eligible for linkage-to-care services. Linkage support was accepted by 86% of positive MSM, of which 66.7% were linked to services in less than 90 days. The MTU resulted in the lowest cost per MSM tested ($137 per test), followed by self-testing ($247). CONCLUSIONS: AHA offered MSM access to HTC through innovative strategies operating in alternative sites and schedules. It presented the Curitiba HIV/AIDS community the opportunity to monitor HIV-positive MSM from diagnosis to treatment uptake. Self-testing emerged as a feasible strategy to increase MSM access to HIV-testing through virtual tools and anonymous test kit delivery and pick-up. Cost per test findings in both the MTU and self-testing support expansion to other regions with similar epidemiological contexts.

[Neonatal screening - the challenge of an universal and effective coverage]. / Triagem neonatal - o desafio de uma cobertura universal e efetiva.

Newborn screening programs (NSP) aim to detect carriers of several congenital diseases among asymptomatic infants in order to warrant effective intervention. Specimen collection is the first step of a process that should be done in an universal and timely manner. A review of coverage and time of collection was done in NSP of several countries. The search was made in various sources, from 1998 to 2008, with "neonatal screening" and "coverage" as key words. The lack of a typical study design did not allow to the rigor required for a systematic review. Data were grouped in macro-regions. Canada had coverage of 71% in 2006 while the European coverage was of 69% in 2004, with data of 38 countries. In Asia and Pacific region, there were data of 19 countries. In Middle East and North Africa, there were data of 4 countries. In Latin America, the coverage was 49% in 2005, with data of 14 countries. In Brazil, coverage was 80%. Twelve reports had information about timeliness. The conclusion is that epidemiological transition has contributed to NSP success. Developed regions had more universal and timelier collection. In Brazil, government initiative increased access to the NSP, but late collections lead to the need of educational actions and participation of professional organizations in developing specific guidelines definition.

Evaluation of STD/AIDS prevention programs: a review of approaches and methodologies.

The article presents a review of approaches and methodologies in the evaluation of STD/AIDS prevention programs, searching for theoretical and methodological support for the institutionalization of evaluation and decision-making. The review included the MEDLINE, SciELO, and ISI Web of Science databases and other sources like textbooks and congress abstracts from 1990 to 2005, with the key words: "evaluation", "programs", "prevention", "STD/AIDS", and similar terms. The papers showed a predominance of quantitative outcome or impact evaluative studies with an experimental or quasi-experimental design. The main use of evaluation is accountability, although knowledge output and program improvement were also identified in the studies. Only a few evaluative studies contemplate process evaluation and its relationship to the contexts. The review aimed to contribute to the debate on STD/AIDS, which requires more effective, consistent, and sustainable decisions in the field of prevention.

Trends and characteristics of AIDS mortality in the Rio de Janeiro city after the introduction of highly active antiretroviral therapy.

We examined the characteristics of AIDS mortality in Rio de Janeiro city from 1995 to 2003. During this period, highly active antiretroviral therapy with protease inhibitors was made available, and it changed the pattern of the epidemics. There was a 47.5% reduction in the number of AIDS deaths within the period, with an increase in the proportion of women among the deceased; their schooling was lower than that of the men, similar to the trends of the national-level epidemics. The main place of death changed from university hospitals to emergency rooms. The proportion of cases reported to the National Diseases Surveillance System (SINAN) reported only through the death certificate remained high. Although there is free distribution of antiretrovirals by the public health system, many patients still lack access to diagnosis and treatment. We need to give priority to access to anti-HIV testing and treatment, to increase the quality of care and to look into the issue of adherence in order to further reduce AIDS mortality.

[Strengths and limitations of the Rio de Janeiro Municipal AIDS Information System as an instrument for epidemiological surveillance]. / O sistema de informação de AIDS do Município do Rio de Janeiro: suas limitações e potencialidades enquanto instrumento da vigilância epidemiológica.

This study analyzes the Rio de Janeiro Municipal AIDS Information System, specifically the system's strengths and limitations in the epidemic's current context, from a broader perspective of epidemiological surveillance. The objective was to provide a brief description of the system, considering its different components. The authors further analyzed records pertaining to the reporting and investigation of AIDS cases from 1985 to 1995 and an update of the database as a contribution to the system's quality. The results showed improvement in the consistency of the AIDS database, particularly for the following variables: occupation, neighborhood, school, and exposure category, although the study found concrete limitations in the system's design and structure for dealing with the complexity and heterogeneity of AIDS surveillance. The study thus identified the need to construct an efficient HIV/AIDS surveillance system, based on epidemiological indicators aimed at monitoring and evaluating changes in the epidemiological pattern and analysis of the impact on morbidity and mortality resulting from access to more efficient forms of prevention and new treatments.
