Machine learning and comorbidity network analysis for hospitalized patients with COVID-19 in a city in Southern Brazil.

The large amount of data generated during the COVID-19 pandemic requires advanced tools for the long-term prediction of risk factors associated with COVID-19 mortality with higher accuracy. Machine learning (ML) methods directly address this topic and are essential tools to guide public health interventions. Here, we used ML to investigate the importance of demographic and clinical variables on COVID-19 mortality. We also analyzed how comorbidity networks are structured according to age groups. We conducted a retrospective study of COVID-19 mortality with hospitalized patients from Londrina, Parana, Brazil, registered in the database for severe acute respiratory infections (SIVEP-Gripe), from January 2021 to February 2022. We tested four ML models to predict the COVID-19 outcome: Logistic Regression, Support Vector Machine, Random Forest, and XGBoost. We also constructed a comorbidity network to investigate the impact of co-occurring comorbidities on COVID-19 mortality. Our study comprised 8358 hospitalized patients, of whom 2792 (33.40%) died. The XGBoost model achieved excellent performance (ROC-AUC = 0.90). Both permutation method and SHAP values highlighted the importance of age, ventilatory support status, and intensive care unit admission as key features in predicting COVID-19 outcomes. The comorbidity networks for old deceased patients are denser than those for young patients. In addition, the co-occurrence of heart disease and diabetes may be the most important combination to predict COVID-19 mortality, regardless of age and sex. This work presents a valuable combination of machine learning and comorbidity network analysis to predict COVID-19 outcomes. Reliable evidence on this topic is crucial for guiding the post-pandemic response and assisting in COVID-19 care planning and provision.

Severe Acute Respiratory Syndrome by SARS-CoV-2 Infection or Other Etiologic Agents Among Brazilian Indigenous Population: An Observational Study from the First Year of Coronavirus Disease (COVID)-19 Pandemic.

BACKGROUND: Indigenous peoples are vulnerable to pandemics, including to the coronavirus disease (COVID)-19, since it causes high mortality and specially, the loss of elderly Indigenous individuals. METHODS: The epidemiological data of severe acute respiratory syndrome (SARS) by SARS-CoV-2 infection or other etiologic agents (OEA) among Brazilian Indigenous peoples during the first year of COVID-19 pandemic was obtained from a Brazilian Ministry of Health open-access database to perform an observational study. Considering only Indigenous individuals diagnosed with SARS by COVID-19, the epidemiology data were also evaluated as risk of death. The type of sample collection for virus screening, demographic profile, clinical symptoms, comorbidities, and clinical evolution were evaluated. The primary outcome was considered the death in the Brazilian Indigenous individuals and the secondary outcome, the characteristics of Brazilian Indigenous infected by SARS-CoV-2 or OEA, as the need for intensive care unit admission or the need for mechanical ventilation support. The statistical analysis was done using Logistic Regression Model. Alpha of 0.05. FINDINGS: A total of 3,122 cases of Indigenous individuals with SARS in Brazil were reported during the first year of the COVID-19 pandemic. Of these, 1,994 were diagnosed with COVID-19 and 730/1,816 (40.2%) of them died. The death rate among individuals with SARS-CoV-2 was three-fold increased when compared to the group of individuals with OEA. Several symptoms (myalgia, loss of smell, and sore throat) and comorbidities (cardiopathy, systemic arterial hypertension, and diabetes mellitus) were more prevalent in the COVID-19 group when compared to Indigenous individuals with OEA. Similar profile was observed considering the risk of death among the Indigenous individuals with COVID-19 who presented several symptoms (oxygen saturation <95%, dyspnea, and respiratory distress) and comorbidities (renal disorders, cardiopathy, and diabetes mellitus). The multivariate analysis was significant in differentiating between the COVID-19-positive and non-COVID-19 patients [X2 (7)=65.187; P-value<0.001]. Among the patients' features, the following contributed in relation to the diagnosis of COVID-19: age [≥43 years-old [y.o.]; OR=1.984 (95%CI=1.480-2.658)]; loss of smell [OR=2.373 (95%CI=1.461-3.854)]; presence of previous respiratory disorders [OR=0.487; 95%CI=0.287-0.824)]; and fever [OR=1.445 (95%CI=1.082-1.929)]. Also, the multivariate analysis was able to predict the risk of death [X2 (9)=293.694; P-value<0.001]. Among the patients' features, the following contributed in relation to the risk of death: male gender [OR=1.507 (95%CI=1.010-2.250)]; age [≥60 y.o.; OR=3.377 (95%CI=2.292-4.974)]; the need for ventilatory support [invasive mechanical ventilation; OR=24.050 (95%CI=12.584-45.962) and non-invasive mechanical ventilation; OR=2.249 (95%CI=1.378-3.671)]; dyspnea [OR=2.053 (95%CI=1.196-3.522)]; oxygen saturation <95% [OR=1.691 (95%CI=1.050-2.723)]; myalgia [OR=0.423 (95%CI=0.191-0.937)]; and the presence of kidney disorders [OR=3.135 (95%CI=1.144-8.539)]. INTERPRETATION: The Brazilian Indigenous peoples are in a vulnerable situation during the COVID-19 pandemic and presented an increased risk of death due to COVID-19. Several factors were associated with enhanced risk of death, as male sex, older age (≥60 y.o.), and need for ventilatory support; also, other factors might help to differentiate SARS by COVID-19 or by OEA, as older age (≥43 y.o.), loss of smell, and fever.

COVID-19 and zoonoses in Brazil: Environmental scan of one health preparedness and response.

The emergence of the COVID-19 pandemic reinforced the central role of the One Health (OH) approach, as a multisectoral and multidisciplinary perspective, to tackle health threats at the human-animal-environment interface. This study assessed Brazilian preparedness and response to COVID-19 and zoonoses with a focus on the OH approach and equity dimensions. We conducted an environmental scan using a protocol developed as part of a multi-country study. The article selection process resulted in 45 documents: 79 files and 112 references on OH; 41 files and 81 references on equity. The OH and equity aspects are poorly represented in the official documents regarding the COVID-19 response, either at the federal and state levels. Brazil has a governance infrastructure that allows for the response to infectious diseases, including zoonoses, as well as the fight against antimicrobial resistance through the OH approach. However, the response to the pandemic did not fully utilize the resources of the Brazilian state, due to the lack of central coordination and articulation among the sectors involved. Brazil is considered an area of high risk for emergence of zoonoses mainly due to climate change, large-scale deforestation and urbanization, high wildlife biodiversity, wide dry frontier, and poor control of wild animals' traffic. Therefore, encouraging existing mechanisms for collaboration across sectors and disciplines, with the inclusion of vulnerable populations, is required for making a multisectoral OH approach successful in the country.

Provision of the frequency modulation system for the hearing impaired.

INTRODUCTION: The personal frequency modulation system is an assisted technology resource used in the accessibility of individuals with hearing impairment, being very important in the school environment. Ordinance number 1274/2013 included this device into the Brazilian unified health system. OBJECTIVE: To analyze the distribution the personal frequency modulation system concession in the national territory by the Brazilian unified health system from 2013 to 2017. METHODS: This is an ecological study that uses the 27 federation units and the five geographic regions as analysis units. The population involved students in the age range of 5-17 years who reported severe hearing impairment. The data sources were the ambulatory information system/Brazilian unified health system, the Brazilian institute of geography and statistics and the report no. 58 of the national commission for the incorporation of technologies into Brazilian unified health system, national commission of technologies incorporation of the ministry of health. The spatial analysis was carried out through the percentage of coverage of the frequency modulation system concession per federation unit; the data were then unified in the five geographic regions and descriptive statistical analysis was performed. RESULTS: Between the first and second years, there was an increase of almost 50% in the quantity dispensed, however, there was a progressive decline in the following years. The average coverage of the frequency modulation system in Brazil was 33.4%. The spatial exploratory analysis showed there is a low and uneven distribution in the territory, as the South and Southeast regions had the highest coverage and the North and Northeast regions the lowest, except for the Rio Grande do Norte unit. CONCLUSION: The frequency modulation system concession was below that stipulated by the ministry of health and from 2014 to 2017, the dispensed quantity progressively decreased. There is an unequal distribution in the territory that can be explained by the geographic disposition of hearing health services.

Acute myocardial infarction on YouTube - is it all fake news?

INTRODUCTION AND OBJECTIVES: The Internet is a fundamental aspect of health information. However, the absence of quality control encourages misinformation. We aim to assess the relevance and quality of acute myocardial infarction videos shared on YouTube (www.youtube.com) in Portuguese. METHODS: We analyzed 1,000 videos corresponding to the first 100 search results on YouTube using the following terms (in Portuguese): "cardiac + arrest"; "heart + attack"; "heart + thrombosis"; "coronary + thrombosis"; "infarction - brain", "myocardial + infarction" and "acute + myocardial + infarction". Irrelevant (n=316), duplicated (n=345), without audio (n=24) or non-Portuguese (n=106) videos were excluded. Included videos were assessed according to source, topic, target audience and scientific inaccuracies. Quality of information was assessed using The Health on the Net Code (HONCode from 0 to 8) and DISCERN (from 0 to 5) scores - the higher the score, the better the quality. RESULTS: 242 videos were included. The majority were from independent instructors (n=95, 39.0%) and were addressed to the general population (n=202, 83.5%). One third of the videos (n=79) contained inaccuracies while scientific society and governmental/health institution videos had no inaccuracies. The mean video quality was poor or moderate; only one video was good quality without any inaccuracies. Governmental/health institutions were the source with the best quality videos (HONCode 4±1, DISCERN 2±1). CONCLUSIONS: One third of the videos had irrelevant information and one third of the relevant ones contained inaccuracies. The average video quality was poor; therefore it is important to define strategies to improve the quality of online health information.

Trends and spatial distribution of hepatitis B in pregnant women in Brazil / Tendência e distribuição espacial da hepatite B em gestantes no Brasil

Abstract Objectives: to analyze the trend and spatial distribution of hepatitis B in pregnant women in Brazil. Methods: ecological study based on all notified cases of hepatitis B in pregnant women through the Information System for Notifiable Diseases - Sinan between 2009 and 2018. Hepatitis B virus (HBV) detection rates were calculated in all municipalities. Spatial analysis was performed using the Global Moran Index for global data and local indicators of spatial association (Lisa) for the 5,570 municipalities. For trend analysis by State, the Prais-Winsten generalized linear regression model was used. Results: 15,253 pregnant women with HBV were reported. High detection rates were observed in the municipalities of São Miguel da Boa Vista-SC (68.96/1000 live births (LB)), Araguaiana-MT (68.18/1000 LB), Reserva do Cabaçal-MT (80, 00/1,000 LB), São Geraldo da Piedade-MG (75/1000 LB), Porto Mauá-RS (111, 11/1000 LB), in the respective bienniums. Moran (I) (I=0.056) showed a positive spatial association. In Lisa, 78 municipalities were included in the high-high cluster, 51.28% in the South region and 48 in the low-low cluster with 72.91% in the Southeast. There was an increasing trend in Maranhão (p=0.004) and Pernambuco (p=0.007) and a decrease in Mato Grosso (p=0.012), Paraná (p=0.031) and Santa Catarina (p=0.008). Conclusion: the detection of hepatitis B in pregnant women was observed in most Brazilian municipalities, with an increasing trend in two states and a decrease in three others.

Abstract Objectives: to describe the prevalence of malnutrition (underweight, low height, and overweight) in children aged six to 59 months and its spatial distribution in the city of Beira, Mozambique. Methods: an exploratory cross-sectional study was conducted between October and November 2019, involving 407 children aged six to 59 months. The sample size calculation was based on the prevalence of height-for-age deficit. Anthropometric data were analyzed using Anthro version and the prevalence of malnutrition was presented through thematic maps generated in Quantum Geographic Information System (QGIS). Results: the main findings revealed a prevalence of 27.0% for low height/age, 7.9% for underweight/height, and 4.7% for overweight. Conclusions: the spatial distribution highlighted that both urban and peri-urban areas of the city showed similar prevalence rates for the three forms of malnutrition. The prevalence of malnutrition in Beira is high, with deficit height/age being the most significant expression, while overweight is diffusely distributed.

Resumo Objetivos: descrever a prevalência da má nutrição (baixo peso, baixa estatura e excesso de peso) em crianças de seis a 59 meses e sua distribuição espacial na cidade de Beira, Moçambique. Métodos: estudo transversal exploratório, realizado entre outubro e novembro de 2019, incluindo 407 crianças de seis a 59 meses. O cálculo da amostra foi baseado na prevalência do déficit estatura/idade. Os dados antropométricos foram analisados no Anthro e a prevalência de má nutrição apresentada por meio de mapas temáticos no Quantum Geographic Information System (QGIS). Resultados: os principais resultados mostram uma prevalência de 27,0% de baixa estatura/idade, 7,9% de baixo peso/estatura e 4,7% de excesso de peso. Conclusões: a distribuição espacial evidenciou que as áreas urbanas e periurbanas da cidade apresentavam prevalências similares das três formas de má nutrição. A prevalência da má nutrição em Beira é alta, embora o déficit estatura/idade seja a sua maior expressão, estando o excesso de peso difusamente distribuído.

Análise da clareza metodológica como dimensão de qualidade do Cadastro Nacional de Estabelecimentos de Saúde / Analysis of methodological clarity as a quality dimension of the National Register of Health Establishments

RESUMO Este artigo analisa a dimensão de qualidade clareza metodológica do Cadastro Nacional de Estabelecimentos de Saúde (CNES), considerando a abordagem das formas de contratação inseridas no sistema. Trata-se de uma pesquisa documental com abordagem qualitativa, que analisou o CNES e seus documentos. Foram selecionados os documentos que contemplaram os descritores: tabela de vínculos de profissionais e/ou formas de contratação. A partir do conceito adotado para a dimensão de qualidade clareza metodológica, foram delineadas as categorias acessibilidade, conteúdo, variáveis, linguagem e usabilidade. No período de 2005 a 2020, foram publicados 17 documentos. Desses, três documentos se sobressaíram: o Leia-me da versão, a Tabela de Domínios e o Manual de preenchimento do CNES. O site do CNES passava por uma reestruturação, e nem todas as funcionalidades estavam devidamente implementadas. O site atual apresentou uma interface mais moderna e de fácil compreensão. A mudança da variável esfera administrativa para natureza jurídica, em 2015, pode dificultar a análise em série histórica. Evidencia-se que o CNES carece de melhor atenção quanto à clareza metodológica, considerando a abordagem das formas de contratação dos profissionais de saúde, inseridas no sistema.

ABSTRACT This article analyzes the quality dimension of methodological clarity of the National Registry of Health Establishments (CNES), considering the approach to forms of contracting in the system. This is a documentary research with a qualitative approach, which analyzed the CNES and its documents. Documents that included the following were selected: table of professional relationships and/or forms of hiring. Based on the concept adopted for the dimension of methodological clarity quality, the categories accessibility, content, variables, language, and usability were outlined. In the period from 2005 to 2020, 17 documents were published. Of those, three documents stood out: The version's Readme, the Domain Table, and the CNES Filling Manual. The CNES website underwent restructuring and not all features were completed. The current website has a more modern and easy-to-understand interface. The change from the administrative sphere variable to the legal nature, in 2015, may make historical series analysis difficult. It is evident that the CNES pays more attention to methodological clarity, considering the approach to the ways of hiring health professionals, included in the system.

Maternal health surveillance panel: a tool for expanding epidemiological surveillance of women's health and its determinants / Painel de vigilância da saúde materna: uma ferramenta para ampliação da vigilância epidemiológica da saúde das mulheres e seus determinantes

ABSTRACT Objective: To present the methodology used in the development of two products for maternal health surveillance and its determinants and discuss their possible uses. Methods: Based on a theoretical model of the determinants of maternal death and databases of Brazilian health information systems, two free products were developed: an interactive panel "surveillance of maternal health" and an educational material "Aparecida: a story about the vulnerability of Brazilian women to maternal death", both available on the website of the Brazilian Obstetric Observatory. Results: More than 30 indicators were calculated for the period 2012-2020, containing information on socioeconomic conditions and access to health services, reproductive planning, prenatal care, delivery care, conditions of birth and maternal mortality and morbidity. The indicators related to severe maternal morbidity in public hospitalizations stand out, calculated for the first time for the country. The panel allows analysis by municipality or aggregated by health region, state, macro-region and country; historical series analysis; and comparisons across locations and with benchmarks. Information quality data are presented and discussed in an integrated manner with the indicators. In the educational material, visualizations with national and international data are presented, aiming to help in the understanding of the determinants of maternal death and facilitate the interpretation of the indicators. Conclusion: It is expected that the two products have the potential to expand epidemiological surveillance of maternal health and its determinants, contributing to the formulation of health policies and actions that promote women's health and reduce maternal mortality.

RESUME Objetivo: Apresentar a metodologia utilizada no desenvolvimento de dois produtos para a vigilância da saúde materna e seus determinantes e discutir as suas possíveis utilizações. Métodos: A partir de modelo teórico dos determinantes do óbito materno e bases de dados dos sistemas de informação em saúde brasileiros, foram desenvolvidos dois produtos gratuitos: um painel interativo denominado "Vigilância da saúde materna" e um material educativo chamado "Aparecida: uma história sobre a vulnerabilidade da mulher brasileira à morte materna", ambos disponíveis no site do Observatório Obstétrico Brasileiro. Resultados: Foram calculados mais de 30 indicadores para o período 2012-2020, contendo informações sobre condições socioeconômicas e de acesso a serviços de saúde, planejamento reprodutivo, assistência pré-natal, assistência ao parto, condições de nascimento e mortalidade e morbidade materna. Destacam-se os indicadores relacionados à morbidade materna grave em internações públicas, calculados pela primeira vez para o país. O painel permite análises por município ou agregadas por região de saúde, unidade da federação, macrorregião e país; análises de série histórica; e comparações entre localidades e com padrões de referência. Dados de qualidade da informação são apresentados e discutidos de forma integrada aos indicadores. No material educativo, visualizações com dados nacionais e internacionais são apresentadas, visando auxiliar na compreensão dos determinantes do óbito materno e facilitar a interpretação dos indicadores. Conclusão: Espera-se que os produtos tenham o potencial de ampliar a vigilância epidemiológica da saúde materna e seus determinantes, contribuindo para a formulação de políticas e ações de saúde que promovam a saúde das mulheres e reduzam a mortalidade materna.

Profile of hospital admissions for migraine and headache disorders in children and adolescents in Brazil between 2013 and 2023 / Perfil das internações hospitalares por distúrbios de enxaqueca e cefaleia em crianças e adolescentes no Brasil entre 2013 e 2023

INTRODUCTION: Migraine is a chronic neurological disease, with a prevalence of 15.2% in Brazil. It is defined as an abnormal neurovascular reaction that occurs in a genetically vulnerable individual. Clinically manifests itself in recurrent episodes of headache associated with other symptoms, dependent on triggering factors. OBJECTIVE: To describe the epidemiological profile of hospital admissions of children and adolescents for migraine and other headache disorders. METHODS: This was a retrospective and descriptive epidemiological study carried out with data extracted from the Brazilian Unified Health System's Hospital Information System (SIH/SUS), indexed to the Department of Informatics of the Unified Health System (DATASUS). Hospital admissions were selected based on age groups, with an emphasis on children under nine years old and adolescents between 10 and 19 years old, residing in Brazil, between July 2013 and June 2023. RESULTS: Of 93,821 hospital admissions, there were 16,149 hospitalizations (17.2%) of children and adolescents (62.5% women and 37.5% men) due to migraine and other headache disorders. There was a predominance of the age group between 15 and 19 years old (50.2%), with a higher number of cases in the Southeast region (35.9%) and of brown ethnicity (42.6%). Over 10 years, there was a progressive increase in the number of hospital admissions, reaching a peak in 2019 (1,925/16,149; 11.9%), followed by a decline in 2020 and increasing again in subsequent years. Twenty-four deaths were found (24/16,149; 0.1%), 13 men and 11 women, with a predominance in the age group of 15 to 19 years (45.8%), coming from the Northeast region (58.3 %) and of brown ethnicity (58.4%). Deaths occurred predominantly in the years 2022 and 2023 (46.6%).

Oral cancer: analysis of the clarity of publications in Instagram profiles of official health agencies in Brazil / Câncer bucal: análise da clareza das publicações realizadas em perfis do Instagram de órgãos oficiais de saúde do Brasil

Abstract This article aims to analyze the clarity and engagement measures of publications on oral cancer in the Instagram profiles of official health agencies in Brazil. An infodemiological study was conducted with 81 profiles. Data collected concerned content classification, account and media, manner of addressing the topic, number of posts, likes, comments, views and hashtags. The clarity of the educational publications was assessed with the Brazilian version of the Clear Communication Index (BR-CDC-CCI). Data analysis involved Spearman's correlation and the Mann-Whitney test (α = 5%). A total of 775 publications on oral cancer were found. The average BR-CDC-CCI score was 69.8 (SD = 15.5). The clarity of the information was adequate in 9.5% of the educational publications. Positive correlations were found between the number of likes and engagement (comments [r = 0.49], views [r = 0.96]), number of hashtags (r = 0.13) and year of publication (r = 0.21). Publications from the Health Ministry had a significantly higher BR-CDC-CCI score compared to the other profiles. Publications on oral cancer were correlated with engagement, year of publication and number of hashtags. Public agencies increased publications to reach the population, but the clarity of the content was low.

Resumo O objetivo do artigo é analisar a clareza e as medidas de engajamento das publicações sobre câncer bucal nos perfis do Instagram dos órgãos oficiais de saúde no Brasil. Realizou-se um estudo infodemiológico com 81 perfis. Foram coletados dados sobre classificação do conteúdo, conta e mídia, abordagem do tema, número de postagens, curtidas, comentários, visualizações e hashtags. A clareza das publicações educativas foi avaliada pela versão brasileira do Clear Communication Index (BR-CDC-CCI). A análise dos dados envolveu a correlação de Spearman e o teste de Mann-Whitney (α = 5%). Foram encontradas 775 publicações sobre câncer bucal. O escore médio do BR-CDC-CCI foi 69,8 (DP = 15,5). A clareza das informações foi adequada em 9,5% das publicações educativas. Correlações positivas foram encontradas entre o número de curtidas e engajamento (comentários [r = 0,49], visualizações [r = 0,96]), número de hashtags (r = 0,13) e ano de publicação (r = 0,21). Publicações do Ministério da Saúde apresentaram escore do BR-CDC-CCI significativamente maior do que os demais perfis (p = 0,01). As publicações sobre câncer bucal foram correlacionadas com engajamento, ano de publicação e número de hashtags. Os órgãos públicos aumentaram as publicações para atingir a população, mas a clareza do conteúdo foi baixa.

Percepções das mulheres grávidas sobre as fontes de informação relativas ao vírus Zika: um estudo qualitativo / Pregnant women's perceptions on information sources on Zika virus: a qualitative study

Resumo A epidemia do vírus Zika (ZIKV) teve impacto sanitário, psicossocial e econômico sobre pessoas em idade reprodutiva. A principal preocupação foi a infecção durante a gravidez devido a possível transmissão vertical e sua associação com resultados fetais e infantis adversos, conhecida como síndrome congênita associada à infecção pelo Vírus Zika (SCZ). Este estudo qualitativo utiliza a fenomenologia e a teoria fundamentada. O estudo inclui entrevistas com 98 mulheres, parte grávida durante a epidemia de ZIKV no Brasil, Colômbia e Porto Rico e que tiveram filhos com SCZ ou sem comprometimento neurológico diagnosticado. Além disso, o estudo inclui um grupo de mulheres grávidas durante a pandemia de COVID-19 nos mesmos países. Em ambos os grupos, as entrevistadas tinham diferentes níveis de conhecimento sobre ZIKV. O estudo constatou que as mensagens veiculadas por meio da mídia eram alarmistas; em contraste com as informações fornecidas por profissionais de saúde, consideradas mais confiáveis. Mulheres gestantes durante a epidemia do ZIKV relataram ter recebido seu diagnóstico de infecção por ZIKV e SCZ tardiamente ou após o parto. O estudo destaca as necessidades das mulheres grávidas em cenários de alto risco, a importância de processos de educação em saúde e a necessidade de reforçar a comunicação e a educação continuada.

Abstract The Zika virus (ZIKV) epidemic had a sanitary, psychosocial, and economic impact on individuals of reproductive age. The primary concern revolved around infection during pregnancy due to possible vertical transmission and its association with adverse fetal and infant outcomes, known as Congenital Zika Syndrome (CZS). This qualitative study employs phenomenology and grounded theory. This study includes interviews with 98 women, some pregnant during the ZIKV epidemic in Brazil, Colombia, and Puerto Rico, who had children with CZS or without diagnosed neurological impairment. Additionally, the study included a group of women who were pregnant during the Covid-19 pandemic in these same countries. In both groups, interviewees had varying levels of knowledge about ZIKV. The study found that messages conveyed through the media tended to be alarmist, in contrast to the information provided by healthcare professionals, which was considered more trustworthy. Pregnant women during the ZIKV epidemic reported receiving their ZIKV and CSZ infection diagnoses late, either during or after childbirth. The study underscores the needs of pregnant women in high-risk scenarios, the importance of health education processes, and the necessity to reinforce communication and continuing education.

Violência interpessoal em mulheres transgêneras e cisgêneras nos municípios brasileiros: tendências e características / Interpersonal violence against transgender and cisgender women in Brazilian municipalities: trends and characteristics

Resumo A violência contra mulher caracteriza-se pela dominação simbólica masculina com pilares no patriarcado, expressando a desigualdade de gênero existente na sociedade. O objetivo deste estudo é analisar a notificação de violência interpessoal em mulheres cisgêneras e transgêneras, de 20 a 59 anos, nos municípios brasileiros, no período de 2015 a 2021. Trata-se de estudo do tipo painéis repetidos, utilizando dados do sistema de informação, e análise de tendência temporal pelo método Prais-Winsten. Foram elegíveis 605.983 notificações, sendo 1,8% de transgêneras. As notificações foram registradas em 84,8% dos municípios para mulheres cisgêneras e 31,7% para transgêneras. Houve predomínio em jovens (71,9%) e negras (55,3%), sendo proporcionalmente maior entre as transgêneras (p<0,001). A maioria das notificações foi de violência física (84,8%); seguida de violência psicológica (40,1%), sendo maior nas cisgêneras (p<0,001) e com redução no período para as transgêneras (β=-0,71; p=0,005). A notificação de violência ainda não reflete a realidade, em particular para mulheres transgêneras. A violência psicológica, entretanto, que costuma ser o início do ciclo de agressão, já ocupa o segundo lugar entre as notificações no país, apesar dos retrocessos vivenciados nos últimos anos.

Abstract Violence against women is characterised by male symbolic domination underpinned by patriarchy and expressing gender inequality in society. This study examined reporting of interpersonal violence against cisgender and transgender women 20 to 59 years old in Brazilian municipalities, from 2015 to 2021. This repeat panel study used data from the information system, and time-trend analysis by the Prais-Winsten method. A total of 605,983 notifications were eligible, 1.8% of which involved transgender women. Notifications regarding cisgender women were recorded in 84.8% of the municipalities and transgender women, in 31.7%. Notifications involved predominantly women who were younger (71.9%) and black (55.3%), and proportionally more transgender women (p<0.001). Most notifications were of physical violence (84.8%), followed by psychological violence (40.1%), which was higher among cisgender women (p<0.001) and at shorter intervals among transgender women (β=-0.71; p=0.005). Notifications of violence still do not reflect the realities, particularly as regards transgender women. Psychological violence, however, which usually starts the cycle of aggression, now ranks second among notifications in Brazil, despite conservative reverses of recent years.
