Detection of HPV DNA in vaginal samples self-collected by women living with HIV treated through the Brazilian public health system: Prevalence and analysis of risk factors

ABSTRACT Background: Women living with human immunodeficiency virus (HIV) (WLWH) are more likely to be infected with the oncogenic human papillomavirus (HPV). We assessed the prevalence of high-risk (HR) (16/18/31/33/35/39/45/51/52/56/58/59/68/73/82), probable high-risk (pHR) (26/53/66), and low-risk (LR) (6/11/40/42/43/44/54/61/70) HPV types and their associated risk factors. Methods: This cross-sectional study of WLWH aged 18-64 years included one laboratory and eight HIV-specialty healthcare facilities in the pilot network. Descriptive statistics were used to assess sociodemographic and behavioral characteristics. Adjusted analyses were conducted to evaluate risk factors associated with HR and/or pHR HPV infection in WLWH. Results: From May/2021 to May/2022, 1,914 (92.5%) WLWH participated in the pilot study and had valid HPV-DNA results of self-collected vaginal samples. The median age of the participants was 45 years, 60.1% had ≥ 9 years of schooling, 80.5% were ≤ 18 years at first sexual intercourse, and 51.7% had > 4 sexual partners throughout life. The prevalence of any HPV type, HR HPV, pHR HPV, and LR HPV was 65.8%, 49.6%, 16.7%, and 40.0%, respectively. Age was inversely associated with pHR and/or HR-HPV (p < 0.001), and education level was inversely associated with HR-HPV (p = 0.003) types. Any HR or pHR was associated with being single (p = 0.029) and exchanging sex for drugs (p = 0.037). Conclusions: The prevalence of HPV, especially HR HPV, among WLWH is high in Brazil, highlighting the need for HPV screening in this population. Self-collection of vaginal samples is an important strategy for increasing testing access.

Mapping the tuberculosis scientific landscape among BRICS countries: a bibliometric and network analysis

BACKGROUND The five BRICS (Brazil, Russian, Indian, China, and South Africa) countries bear 49% of the world's tuberculosis (TB) burden and they are committed to ending tuberculosis. OBJECTIVES The aim of this paper is to map the scientific landscape related to TB research in BRICS countries. METHODS Were combined bibliometrics and social network analysis techniques to map the scientific publications related to TB produced by the BRICS. Was made a descriptive statistical data covering the full period of analysis (1993-2016) and the research networks were made for 2007-2016 (8,366 records). The bubble charts were generated by VantagePoint and the networks by the Gephi 0.9.1 software (Gephi Consortium 2010) from co-occurrence matrices produced in VantagePoint. The Fruchterman-Reingold algorithm provided the networks' layout. FINDINGS During the period 1993-2016, there were 38,315 peer-reviewed, among them, there were 11,018 (28.7%) articles related by one or more authors in a BRICS: India 38.7%; China 23.8%; South Africa 21.1%; Brazil 13.0%; and Russia 4.5% (The total was greater than 100% because our criterion was all papers with at least one author in a BRICS). Among the BRICS, there was greater interaction between India and South Africa and organisations in India and China had the highest productivity; however, South African organisations had more interaction with countries outside the BRICS. Publications by and about BRICS generally covered all research areas, especially those in India and China covered all research areas, although Brazil and South Africa prioritised infectious diseases, microbiology, and the respiratory system. MAIN CONCLUSIONS An overview of BRICS scientific publications and interactions highlighted the necessity to develop a BRICS TB research plan to increase efforts and funding to ensure that basic science research successfully translates into products and policies to help end the TB epidemic.

Tuberculosis: renewed challenge in Brazil

Abstract This article reviews tuberculosis control actions performed over the last decade, at a global level. The perspectives for the fulfillment of the goals of the new Global Tuberculosis Elimination Plan are described, where the insertion of social protection (Pillar 2) and research (Pillar 3) will play an innovative and strategic role, especially in high-burden countries, like Brazil.

Cadastro Nacional de Estabelecimentos de Saúde como ferramenta de análise da descentralização do atendimento da tuberculose para a atenção básica / Brazilian National Registry of Healthcare Establishments as a tool for the analysis of decentralization of tuberculosis treatment to basic care services / Registro Nacional de Establecimientos de Salud como herramienta de análisis de la descentralización de la atención a la tuberculosis en la atención básica

Resumo: Os objetivos deste artigo foram validar um método de classificação dos serviços de saúde (atenção básica vs. outros níveis) e descrever a descentralização do atendimento da tuberculose (TB) para a atenção básica no Brasil no período de 2002 a 2016. Os serviços de saúde que notificaram e acompanharam pessoas com TB foram classificados como "atenção básica" ou "outros níveis", considerando-se o tipo de estabelecimento registrado no Cadastro Nacional de Estabelecimentos de Saúde (CNES). Foi estimada a concordância entre essa classificação e uma realizada em 2013 pelos programas estaduais e municipais de TB. Posteriormente, utilizando-se o CNES, calculou-se o percentual de pessoas com TB atendidas na atenção básica no período de 2002 a 2016. A concordância foi de 94,4% e o índice kappa global foi 0,86. Houve um incremento relativo de 31,2% do atendimento de TB na atenção básica (50,9% em 2002 para 66,8% em 2016). Todas as regiões apresentaram aumento desse percentual, exceto a Região Sul. A classificação baseada no CNES permitiu analisar a evolução da descentralização do atendimento da TB para a atenção básica no Brasil.

Abstract: This study aimed to validate a method for classification of healthcare services in Brazil (basic care vs. other levels) and describe the decentralization of tuberculosis (TB) care to basic services (2002 to 2016). The healthcare services that reported and followed TB cases were classified as either "basic care" or "other levels" based on the type of establishment registered in the Brazilian National Registry of Healthcare Establishments (CNES, in Portuguese). The study estimated the agreement between this classification with a previous classification performed in 2013 by Brazil's state and local tuberculosis programs. Using the CNES registry, the authors then calculated the percentage of TB patients treated in basic care from 2002 to 2016. Agreement was 94.4%, and overall kappa index was 0.86. There was a relative increment of 31.2% in TB care provided by basic services (from 50.9% in 2002 to 66.8% in 2016). All regions of Brazil showed an increase in this percentage, except the South. The classification based on the CNES registry allowed analyzing the trend in decentralization of TB treatment to basic healthcare services in Brazil.

Los servicios de salud que notificaron y efectuaron el seguimiento a personas con TB fueron clasificados como "atención básica" u "otros niveles", considerándose el tipo de establecimiento registrado en el Registro Nacional de Establecimientos de Salud (CNES). Se estimó la concordancia entre esta clasificación y una realizada en 2013 por los programas estatales y municipales de TB. Posteriormente, utilizando el CNES, se calculó el porcentaje de personas con TB atendidas en la atención básica durante el período de 2002 a 2016. La concordancia fue de 94,4% y el índice kappa global fue 0,86. Hubo un incremento relativo de un 31,2% del manejo de la TB en la atención básica (de un 50,9% en 2002 hasta un 66,8% en 2016). Todas las regiones presentaron un aumento de ese porcentaje, excepto la región Sur. La clasificación, basada en el CNES, permitió analizar la evolución de la descentralización del manejo de la TB hacia la atención básica en Brasil.

Offer of primary care services and detection of tuberculosis incidence in Brazil / Oferta de serviços pela atenção básica e detecção da incidência de tuberculose no Brasil

ABSTRACT OBJECTIVE To evaluate the association between the health services offered by primary care teams and the detection of new tuberculosis cases in Brazil. METHODS This was an ecological study covering all Brazilian municipalities that registered at least one new tuberculosis case (diagnosed between 2012 to 2014 and notified in the Information System of Notifiable Diseases) and with at least one primary care team evaluated by the second cycle of the National Program for Improving Access and Quality of Primary Care (PMAQ-AB). The variables of the PMAQ-AB were classified as proximal or distal, according to their relation with the tuberculosis diagnosis. Then, they were tested hierarchically in multiple models (adjusted by States) using negative binomial regression. RESULTS An increase of 10% in the primary health care coverage was associated with a decrease of 2.24% in the tuberculosis detection rate (95%CI -3.35- -1.11). Regarding the proximal variables in relation to diagnosis, in the multiple model, the detection of tuberculosis was associated with the proportion of teams that conduct contact investigation (increase in Incidence Rate Ratio [IRR] = 2.97%, 95%CI 2.41-3.53), carry out tuberculosis active case finding (increase in IRR = 2.17%, 95%CI 1.48-2.87), and request culture for mycobacteria (increase in IRR = 1.87%, 95%CI 0.98-2.76). CONCLUSIONS The variables related to the search actions were positively associated with the detection of new tuberculosis cases, which suggests a significant contribution to the strengthening of the sensitivity of the surveillance system. On the other hand, primary care coverage was inversely associated with the tuberculosis detection rate, which could represent the overall effect of the primary care on transmission control, probably from the identification and early treatment of cases.

RESUMO OBJETIVO Avaliar a associação entre os serviços de saúde ofertados por equipes de atenção básica e a detecção de casos novos de tuberculose no Brasil. MÉTODOS Estudo ecológico, abrangendo todos os municípios brasileiros que registraram pelo menos um caso novo de tuberculose (diagnosticado entre 2012 a 2014 e notificado no Sistema de Informação de Agravos de Notificação) e com pelo menos uma equipe de atenção básica avaliada pelo segundo ciclo do Programa Nacional de Melhoria do Acesso e da Qualidade da Atenção Básica (PMAQ-AB). As variáveis do PMAQ-AB foram classificadas como próximais ou distais, segundo a sua relação com o diagnóstico de tuberculose. Em seguida, foram testadas hierarquicamente em modelos múltiplos (ajustados por Unidade Federada), usando regressão binomial negativa. RESULTADOS Um incremento de 10% na cobertura da atenção básica esteve associado à redução de 2,24% na taxa de detecção de tuberculose (IC95% -3,35- -1,11). No que se refere às variáveis proximais ao diagnóstico, no modelo múltiplo, a detecção da tuberculose esteve associada à proporção de equipes que: realizam vigilância de contatos (incremento na Razão de Taxas de Incidência [RTI] = 2,97%; IC95% 2,41-3,53); fazem busca ativa de casos de tuberculose (incremento na RTI = 2,17%; IC95% 1,48-2,87); e, ofertam cultura para micobactérias (incremento na RTI = 1,87%; IC95% 0,98-2,76). CONCLUSÕES As variáveis relacionadas às ações de detecção estiveram positivamente associadas à detecção de casos novos de tuberculose, sugerindo uma contribuição significativa ao fortalecimento da sensibilidade do sistema de vigilância. Por outro lado, a cobertura da atenção básica esteve inversamente associada à taxa de detecção de tuberculose, o que poderia representar o efeito global da atenção básica sobre o controle da transmissão, provavelmente, através da identificação e tratamento precoce de casos.
