RESUMO

Resumo O objetivo do artigo é analisar o conteúdo sorofóbico explicitado nas publicações veiculadas nas redes sociais digitais no contexto do HIV e da Aids no Brasil. Trata-se de um estudo qualitativo do tipo exploratório descritivo, de base documental. Os dados obtidos foram avaliados utilizando a metodologia de análise documental por meio da análise de conteúdo temático com auxílio do software NVivo®12 Plus (Windows). Foram gerados 187 códigos, posteriormente agrupados conforme a semântica das palavras, originando cinco categorias temáticas: #VivendoComHIV, #PrecisamosFalarSobreIsso, #OQueÉSOROFOBIA, #SorofobiaéCrime e #SorofobiaNÃO. Os resultados evidenciaram as principais manifestações acerca da sorofobia relacionada ao HIV e à Aids nas redes sociais. O conteúdo compartilhado debateu as dificuldades de viver com uma doença que apresenta dimensões sociais; a relevância de falar e difundir conteúdo sobre o HIV e a Aids; os elementos que compõem o processo de estigmatização e, consequentemente, estruturam a sorofobia na sociedade; os direitos sociais e civis das pessoas vivendo com HIV; as medidas de combate à sorofobia nas instituições de saúde; e as implicações da sorofobia no âmbito da saúde pública.

Abstract The aim of this article is to analyze the serophobic content explicit in the publications published in Digital Social Networks in the context of HIV and AIDS in Brazil. This is a qualitative study of the descriptive exploratory type, based on documents. The data obtained were evaluated using the methodology of documentary analysis through Thematic Content Analysis with the aid of NVivo®12 Plus (Windows). A total of 187 codes were generated, subsequently grouped according to the semantics of the words, originating five thematic categories: #LivingWithHIV, #WeNeedtoTalkAboutIt, #WhatISSEROPHOBIA, #SerophobiaIsACrime, and #NoSerophobia. The results showed the main manifestations of HIV and AIDS-related serophobia on social networks. The shared content discussed the difficulties of living with a disease that has social dimensions; the relevance of talking and disseminating content about HIV and AIDS; the elements that make up the stigmatization process and, consequently, structure serophobia in society; the social and civil rights of people living with HIV; measures to combat serophobia in health institutions; and the implications of serophobia in the field of public health.

RESUMO

Abstract Considering the institution of the Care Network for People with Disabilities (RCPD) in Brazil, this study analyzed the spatial distribution and the temporal trend of implementing specialized services that received financial support in the first eight years of this policy. We realized an ecological study based on the National Register of Health Facilities data from April/2012 to March/2020. A joinpoint regression was used for temporal trend analysis, and thematic maps were produced for spatial analysis of rehabilitation modalities and types of services. The most available services were physical and intellectual rehabilitation. The Southeast and Northeast regions had a higher concentration of specialized services. Despite the lower number of services, there was an average annual growth between 9.6% and 41.3%. This finding indicates an increase in specialized services for people with disabilities in the period analyzed, but care gaps are still being verified in the macro-regions of Brazil.

Resumo Considerando a instituição da Rede de Atenção à Pessoa com Deficiência (RCPD) no Brasil, o estudo analisa a distribuição espacial e a tendência temporal da implantação de serviços especializados que receberam apoio financeiro nos primeiros oito anos dessa política. Realizamos um estudo ecológico com base nos dados do Cadastro Nacional de Estabelecimentos de Saúde no período de abril/2012 a março/2020. Uma regressão joinpoint foi usada para análise de tendência temporal e mapas temáticos foram produzidos para análise espacial de modalidades de reabilitação e tipos de serviços. Os serviços mais disponíveis foram reabilitação física e intelectual. As regiões Sudeste e Nordeste apresentaram maior concentração de serviços especializados. Apesar do menor número de serviços, houve crescimento médio anual entre 9,6% e 41,3%. Esse achado indica aumento de serviços especializados para pessoas com deficiência no período analisado, mas ainda se verificam lacunas assistenciais nas macrorregiões do Brasil.

RESUMO

Resumo: Este artigo apresenta os resultados de uma pesquisa sobre a percepção dos profissionais de saúde sobre a hesitação vacinal infantil relacionada à COVID-19. Baseado no constructo teórico da hesitação vacinal, foi realizada uma pesquisa qualitativa com 86 trabalhadores da atenção primária à saúde (APS) em quatro municípios de quatro estados brasileiros e no Distrito Federal. A análise temática foi realizada e obtiveram-se três categorias: medo, desinformação em vacina e papel dos profissionais de saúde. O medo como motivo de hesitação vacinal gerou reflexões sobre a condução da pandemia pelo Governo Federal, principalmente no que tange à governabilidade por meio desse afeto, e sobre as consequências do uso das plataformas digitais na população. O medo relacionou-se ao fato de a vacina ainda ser percebida como experimental; às possíveis reações adversas; à ausência de estudos de longo prazo; à falsa percepção de risco reduzido da COVID-19 em crianças; e às condutas do Governo Federal geradoras de insegurança nos efeitos da vacina. A desinformação em vacina relacionou-se às fake news sobre a vacina e suas reações; ao fenômeno da infodemia e desinformação; e à ausência de orientação e conhecimento sobre vacinas. Por fim, o trabalho discute o papel fundamental dos profissionais de saúde da APS no aumento da cobertura vacinal devido à confiabilidade perante a população e à proximidade com os territórios, fatores que possibilitam reverter o medo e a desinformação diante das vacinas. Ao longo do trabalho, buscou-se apresentar as convergências entre o conteúdo dos temas delineados e os determinantes da hesitação vacinal e refletir sobre possibilidades para a reconstrução da alta adesão às vacinas infantis.

Abstract: This article presents the results of a study on health professionals' perceptions of childhood vaccine hesitancy related to COVID-19. Based on the theoretical construct of vaccine hesitancy, a qualitative study was conducted with 86 primary health care (PHC) workers in four municipalities in four Brazilian states and in the Federal District. A thematic analysis was performed and three categories were obtained: fear, misinformation about vaccines, and the role of health professionals. Fear as a reason for vaccine hesitancy has led to reflections on the Brazilian Federal Government's management of the pandemic, especially regarding governability and the consequences of the use of digital platforms on the population. Fear was related to the vaccine still being perceived as experimental; to the adverse reactions it may cause; to the lack of long-term studies; to the false perception of reduced risk of COVID-19 in children; and to the Federal Government's behavior, which creates uncertainty about the effects of the vaccine. Vaccine misinformation was related to fake news about the vaccine and its reactions; the phenomenon of infodemic and misinformation; and the lack of guidance and knowledge about vaccines. Finally, the article discusses the fundamental role of PHC workers in increasing vaccination coverage due to the trust among the population and proximity to the territories, factors that enable the reversal of fear and misinformation about vaccines. Throughout the study, authors' sought to show the convergences between the content of the themes outlined and the determinants of vaccine hesitancy and to consider possibilities for rebuilding high adherence to childhood vaccines.

Resumen: Este artículo presenta los resultados de una encuesta sobre la percepción de los profesionales de la salud acerca de la reticencia vacunal infantil relacionada con la COVID-19. Con base en el constructo teórico de la reticencia vacunal, se realizó una encuesta cualitativa con 86 trabajadores de la atención primaria de salud (APS) en 4 municipios de 4 estados brasileños y en el Distrito Federal. Se realizó un análisis temático y se obtuvieron tres categorías: miedo, desinformación sobre vacunas y papel de los profesionales de la salud. El miedo como motivo de reticencia vacunal dio lugar a reflexiones sobre el manejo de la pandemia por parte del Gobierno Federal, sobre todo en lo que respecta a la gobernabilidad por medio de esta afección y las consecuencias del uso de plataformas digitales en la población. El temor se relacionó con el hecho de que la vacuna todavía se percibe como experimental; con las reacciones adversas que puedan provocar; con la ausencia de estudios a largo plazo; con la falsa percepción de riesgo reducido de COVID-19 en niños y con las conductas del Gobierno Federal que generan inseguridad sobre los efectos de la vacuna. La desinformación sobre las vacunas se relacionó con noticias falsas sobre la vacuna y sus reacciones; el fenómeno de la infodemia y la desinformación; y la ausencia de orientación y conocimiento sobre las vacunas. Finalmente, el trabajo discute el papel fundamental de los profesionales de la salud de la APS en el aumento de la cobertura vacunal debido a su confiabilidad entre la población y cercanía a los territorios, factores que permiten revertir el miedo y la desinformación respecto a las vacunas. A lo largo del trabajo, se buscó presentar las convergencias entre el contenido de los temas delineados y los determinantes de la reticencia vacunal y reflexionar sobre las posibilidades para la reconstrucción de una alta adhesión a las vacunas infantiles.

RESUMO

The present study contains an experimental analysis of the vibratory response in a low-cylinder engine motorcycle at varying suspension preloads. Three different speed bumps of varying heights were used to subject the motorcycle to different vibrations. The analysis was carried out in three domains: time, frequency, and time-frequency. A triaxial accelerometer was used to measure the vibrations at the seat of the vehicle. The results indicated that the suspension system became more differentiated as the height of the bumps increased. However, for lower bumps, the action of the three spring preloads studied was quite similar. Quantitatively, only the higher bump showed a significant difference between the set preloads. The spectral distribution revealed that the frequency of interest was below 20 Hz for all the studied cases, which is in the same range of human body natural frequencies. The findings of this research can be utilized to enhance the design of low-cost motorcycles, thereby improving the safety and comfort of their drivers and passengers. This study constitutes a significant step towards developing an affordable system capable of gathering sufficient data to support the creation of evidence-based public health policies and propose new transport industry standards based on field measurements.

RESUMO

Visceral leishmaniasis (VL) is a neglected disease of public and animal health importance. With the urbanization of the disease, there is evidence of a temporal correlation between the occurrence of human (HVL) and canine (CVL) visceral leishmaniasis, usually with cases in dogs preceding those in humans. In this context, the objective of this study was to develop a time series model suitable for canine-human transmission of Leishmania infantum. Monthly cases of HVL and CVL from 2006 to 2018 in Belo Horizonte, Minas Gerais, Brazil, were evaluated, and monthly health indicators were calculated for HVL and CVL, i.e., incidence coefficient (HVL_IC) and proportion of seropositive dogs (PSD), respectively. The temporal relationship was evaluated using an autoregressive integrated moving average with exogenous variable (ARIMAX) model for two different periods (January 2006-August 2013 and September 2013-December 2018). During the 13 years studied, 1115 new cases of HVL and 103,358 dogs seropositive for CVL were recorded. HVL_IC and PSD exhibited decreasing trends throughout the first study period (January 2006-August 2013). According to the ARIMAX model adjusted for this period, there was a temporal relationship between HVL_IC and PSD, with HVL_IC being influenced by HVL_IC for the last two and five months and by PSD for the third previous month. For the second study period (September 2013-December 2018), it was not possible to fit an ARIMAX model. This study highlights the improvements made by VL surveillance since 2006 in Belo Horizonte and contributes to a better understanding of the epidemiology of the disease by public health policy-makers, doctors and veterinarians involved in the prevention and control of zoonoses.

RESUMO

The ongoing COVID-19 pandemic is arguably one of the most challenging health crises in modern times. The development of effective strategies to control the spread of SARS-CoV-2 were major goals for governments and policy makers. Mathematical modeling and machine learning emerged as potent tools to guide and optimize the different control measures. This review briefly summarizes the SARS-CoV-2 pandemic evolution during the first 3 years. It details the main public health challenges focusing on the contribution of mathematical modeling to design and guide government action plans and spread mitigation interventions of SARS-CoV-2. Next describes the application of machine learning methods in a series of study cases, including COVID-19 clinical diagnosis, the analysis of epidemiological variables, and drug discovery by protein engineering techniques. Lastly, it explores the use of machine learning tools for investigating long COVID, by identifying patterns and relationships of symptoms, predicting risk indicators, and enabling early evaluation of COVID-19 sequelae.

RESUMO

Introduction: The Human T-lymphotropic virus type 1 (HTLV-1) was the first described human retrovirus. It is currently estimated that around 5 to 10 million people worldwide are infected with this virus. Despite its high prevalence, there is still no preventive vaccine against the HTLV-1 infection. It is known that vaccine development and large-scale immunization play an important role in global public health. To understand the advances in this field we performed a systematic review regarding the current progress in the development of a preventive vaccine against the HTLV-1 infection. Methods: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA®) guidelines and was registered at the International Prospective Register of Systematic Reviews (PROSPERO). The search for articles was performed in PubMed, Lilacs, Embase and SciELO databases. From the 2,485 articles identified, 25 were selected according to the inclusion and exclusion criteria. Results: The analysis of these articles indicated that potential vaccine designs in development are available, although there is still a paucity of studies in the human clinical trial phase. Discussion: Although HTLV-1 was discovered almost 40 years ago, it remains a great challenge and a worldwide neglected threat. The scarcity of funding contributes decisively to the inconclusiveness of the vaccine development. The data summarized here intends to highlight the necessity to improve the current knowledge of this neglected retrovirus, encouraging for more studies on vaccine development aiming the to eliminate this human threat.

RESUMO

Urban agriculture (UA) can be used as an action to promote sustainability in cities and inform public health policies for urban populations. Despite this growing recognition, its implementation still presents challenges in countries in the Global North and Global South. BACKGROUND: In this context, this systematic review aims to identify the development of frameworks for the implementation of UA as a sustainable action and its main opportunities and shortcomings in meeting urban socio-environmental demands. METHODS: In this review, using the PRISMA protocol, we evaluated 26 studies on the interplay between UA and sustainability surveyed on the Web of Science to provide an overview of the state of the art. CONCLUSIONS: In summary, it was possible to identify many key challenges in UA adoption, which regard air and soil contamination, availability of green areas, layout of urban infrastructure, food distribution, among others. Due to numerous socio-economic and environmental contextual factors in cities, especially when comparing realities of the Global North and Global South, there is a need to develop a model that can be adaptable to these different contexts. Thus, it is recognized that the concept of sustainability does not present a universal understanding and that in its search it could be argued that one of the most important gaps is still to address social issues in relation to environmental ones.
