Abstract This article aims to characterize the language employed in educational and communications materials about STIs, HIV/AIDS and viral hepatitis produced by the Ministry of Health between 2010 and 2019, identifying elements related to health promotion and disease prevention. We conducted an exploratory descriptive study. The materials were selected by performing a systematic search of the Ministry of Health website focusing on the period 2010-2019. The materials were analyzed to determine the educational approaches adopted. The preventive, educational and personal development approaches were identified in 100% (201), 24.87% (50) and 7.96% (16) of the materials, respectively. The radical and popular education for health approaches were not observed. The almost exclusive focus on the preventive approach reveals that promoting changes in individual habits and behavior alone is not sufficient to combat and solve the problem of STIs, HIV/AIDS and viral hepatitis in Brazil.

Resumo O objetivo do artigo é caracterizar a linguagem utilizada nos materiais educativos e comunicacionais vinculados à temática das IST, do HIV/Aids e hepatites virais produzidos e veiculados pelo Ministério da Saúde no período de 2010 a 2019, identificando elementos de promoção à saúde e de prevenção de doenças. Metodologia descritiva exploratória para a caracterização da linguagem utilizada nos materiais educativos e comunicacionais sobre as IST, do HIV/Aids e hepatites virais. Para a seleção dos materiais educativos, adotou-se a estratégia de busca sistemática realizada no site do Ministério da Saúde do Brasil por um período de dez anos: de 2010 a 2019. Os materiais foram observados por meio dos enfoques educativos. O enfoque preventivo foi identificado em 100% dos materiais analisados (201). O enfoque educativo foi encontrado em 24,87% (50) dos materiais, e o enfoque de desenvolvimento pessoal foi encontrado em 7,96% (16). Os enfoques radical e da educação popular em saúde não foram observados. A atenção quase exclusiva ao enfoque preventivo revela que cuidados individuais isoladamente não são suficientes para combater e sanar o problema das IST, do HIV/Aids e das hepatites virais no Brasil.

Abstract Introduction: The stroke prevention strategy in patients with intracerebral hemorrhage (ICH) and atrial fibrillation (AF) is a clinical dilemma. The aim of this study was to evaluate the management of anticoagulation therapy in patients with AF and admitted with ICH. Methods: We performed a descriptive analysis of patients admitted for ICH from 2009 to 2021. Data collection was carried out by consulting the processes and analyzing demographic, clinical and imaging data, and prior and post--discharge therapy. A comparative analysis of outcomes of anticoagulant therapy was performed between direct oral anticoagulants (DOACs) and vitamin K antagonists (VKAs). Results: A total of 28 patients (22 male patients; median age 75 years) were included in the study, of which 19 were previously on anticoagulation therapy. Only eight (re)started anticoagulation after discharge. There were 19 deaths, of which 17 were in the group without post-discharge anticoagulation; of those, five occurred in the first month after ICH. Conclusion: Most patients did not (re)initiate anticoagulation after ICH, despite being a high-risk group for new cerebrovascular events, which makes the discussion on this topic even more relevant. There was a change in the prescription pattern from VKAs to DOACs, comparing the two periods analyzed.

Resumo Introdução: A estratégia de prevenção secundária em doentes com acidente vascular cerebral hemorrágico (AVCh) e fibrilhação auricular (FA) é um dilema clínico. O objetivo dos autores foi avaliar a introdução ou manutenção de terapêutica hipocoagulante em doentes com FA e internados por AVCh. Métodos: Análise descritiva dos doentes internados por AVCh de 2009 a 2021. Foi feita a colheita de dados pela consulta dos processos e analisados dados demográficos, clínicos, imagiológicos e a terapêutica prévia e após alta. Realizou-se uma análise comparativa da terapêutica hipo-coagulante entre anticoagulantes orais diretos (DOAC) e antagonistas da vitamina K (AVK). Resultados: Um total de 28 doentes (22 do género masculino; mediana de idade de 75 anos) foram incluídos no estudo, dos quais 19 eram hipocoagulados previamente. Destes, oito (re)iniciaram a hipocoagulação após a alta. Verificou-se o óbito em 19 doentes, dos quais 17 pertenciam ao grupo sem hipocoagulação após alta e destes, cinco óbitos foram verificados no primeiro mês após o AVCh. Conclusão: A maioria dos doentes não (re)iniciou hipo-coagulação após AVCh, apesar de serem um grupo de alto risco para novos eventos cerebrovasculares, o que torna a discussão sobre este tema ainda mais relevante. Assistiu-se a uma mudança no padrão de prescrição de AVK para DOAC, comparando os dois períodos em análise.

Resumo Introdução: As lesões vasculares iatrogénicas são uma causa importante de morbilidade e mortalidade após intervenções cirúrgicas ortopédicas ou neurocirúrgicas. Neste artigo, os autores apresentam dois casos clinicos de quasi-iatrogenia vascular. Casos clínicos: Dois casos, um procedimento ortopédico e um procedimento neurocirúrgico, são apresentados. O primeiro caso refere-se a uma mulher de 80 anos com migração do componente acetabular de uma prótese da anca, associado a trombose da veia ilíaca externa. O segundo caso reporta um homem de 27 anos com compressão medular ao nível de D6 por motivo de um hemangioma ósseo. Após a operação, verificou-se a presença de material de fixação (parafuso) fazendo protusão para o lúmen da aorta torácica. Este foi removido num segundo momento. Ambas as operações decorreram sem complicações. Conclusão: Os autores consideram que uma abordagem multidisciplinar contribuiu significativamente para o sucesso dos casos apresentados.

Abstract: En Es Pt

Openness, reliability, identifiability and interoperability of scientific information are increasingly relevant aspects for the scientific community and open research infrastructure. Within open research infrastructure, one of the pillars of Open Science, persistent identifiers are established as a main building block, enabling interoperability between entities such as authors, outputs and institutions. To consolidate and maintain best practices around them, DataCite and ORCID have worked together since their early days and have fostered the development of communities of practice in the adoption of open persistent identifiers. This text frames identifiers within the framework of Open Science and the FAIRification of scientific information. It also presents the joint trajectory of DataCite and ORCID and the concept of communities of practice applied to open persistent identifiers. Finally, it explores the work developed in Ibero-America and possible future scenarios.

RESUMO OBJETIVO Estimar a soroprevalência de anticorpos do vírus SARS-CoV-2 em escolares de quatro a 14 anos de idade residentes no município de São Paulo, segundo variáveis clínicas, demográficas, epidemiológicas e sociais, durante o período de fechamento das escolas como medida de controle da covid-19. MÉTODOS Realizou-se um inquérito sorológico em setembro de 2020 com amostra aleatória estratificada por tipo de rede de ensino (pública municipal, pública estadual e privada). Foi coletada amostra de sangue venoso utilizando-se o teste de imunoensaio de fluxo lateral da fabricante Wondfo para detecção de anticorpos totais contra o vírus SARS-CoV-2. Aplicaram-se questionários semiestruturados para o levantamento de dados clínicos, demográficos, sociais e epidemiológicos. RESULTADOS A soroprevalência de anticorpos do vírus SARS-CoV-2 em escolares foi de 16,6% (IC95% 15,4–17,8). O estudo encontrou soroprevalências mais elevadas na rede pública municipal (18,5%; IC95% 16,6–20,6) e estadual (16,2%; IC95% 14,4–18,2) em relação à rede privada (11,7; IC95% 10,0–13,7) e entre escolares da raça/cor preta e parda (18,4%; IC95% 16,8–20,2) e no estrato social mais vulnerável (18,5%; IC95% 16,9–20,2). A pesquisa identificou menores soroprevalências nos escolares que relataram seguir as medidas recomendadas de proteção contra a covid-19. CONCLUSÃO A soroprevalência de anticorpos contra o vírus SARS-CoV-2 atinge principalmente os escolares socialmente mais vulneráveis. Este estudo pode contribuir para embasar políticas públicas que reforcem a importância da suspensão das aulas presenciais e da necessidade de estratégias de medidas de proteção e acompanhamento do status sorológico daqueles que ainda não foram contemplados no calendário vacinal.

ABSTRACT OBJECTIVE To estimate seroprevalence of SARS-CoV-2 antibodies in schoolchildren aged 4 to 14 years living in the city of São Paulo, according to clinical, demographic, epidemiological, and social variables, during the school closure period as a measure against covid-19 spread. METHODS A serological survey was made in September 2020 with a random sample stratified by school system (municipal public, state public and private) type. A venous blood sample was collected using the Wondfo SARS-CoV-2 Antibody Test (lateral flow method) for detection of total SARS-CoV-2 virus antibodies. Semi-structured questionnaires were applied to collect clinical, demographic, social, and epidemiological data. RESULTS Seroprevalence of SARS-CoV-2 antibodies in schoolchildren was of 16.6% (95%CI 15.4–17.8). The study found higher seroprevalence in the municipal (18.5%; 95%CI 16.6–20.6) and state (16.2%; 95%CI 14.4–18.2) public school systems compared to the private school system (11.7; 95%CI 10.0–13.7), among black and brown students (18.4%; 95%CI 16.8–20.2) and in the most vulnerable social stratum (18.5 %;95%CI 16.9–20.2). Lower seroprevalence was identified in schoolchildren who reported following the recommended protective measures against covid-19. CONCLUSION Seroprevalence of SARS-CoV-2 antibodies is found mainly in the most socially vulnerable schoolchildren. This study can contribute to support public policies that reinforce the importance of suspending face-to-face classes and developing strategies aimed at protective measures and monitoring of the serological status of those who have not yet been included in the vaccination schedule.

Resumo O objetivo deste estudo foi analisar os fatores relacionados à saúde mental dos agentes comunitários de saúde (ACS) no contexto da COVID-19. Participaram 1.935 ACS de quatro capitais nordestinas e de quatro cidades do interior do Ceará. Foram coletados dados sociodemográficos e profissiográficos; SRQ-20; WHOQOL-Bref; exposição à violência; Escala de Autoeficácia Geral (EAEG); Escala Multidimensional de Suporte Social Percebido (MSPSS); informações relacionadas à COVID-19 e Escala de Ansiedade para Coronavírus (EAC). 40,5% exibiram SRQ > 7, sinalizando altos níveis de transtornos mentais comuns (TMC)/problemas de saúde mental. Utilizou-se a regressão linear múltiplas (backward). Observou-se que o aumento de risco de TCM foi influenciado pelos seguintes fatores: exposição à violência; EAC; não saber se teve COVID-19; desconhecer as variáveis que diminuíam o risco; os domínios físico e psicológico do WHOQOL-Bref; não ter aumento da jornada de trabalho; e não ter tido COVID-19. Os dados revelam a dinâmica multidimensional da saúde mental e ajudam a compreender a relação entre violência comunitária, COVID-19, qualidade de vida, idade e tempo de atuação na ESF com a saúde mental dos ACS.

Abstract This study aimed to analyze the factors related to the mental health of Community Health Workers (ACS) in the COVID-19 context. A total of 1,935 ACS from four Northeastern capitals and four cities in the inland region of Ceará participated. The following data were collected: sociodemographic; professional; SRQ-20; WHOQOL-Bref, exposure to violence, General Self-Efficacy Scale (EAEG), Multidimensional Scale of Perceived Social Support (MSPSS), COVID-19-related information, and the coronavirus anxiety scale (EAC). Approximately 40.5% had SRQ > 7, signaling high levels of Common Mental Disorders (CMD)/mental health issues. We adopted the Multiple linear (backward) regression. We observed that the increased risk of CMD was influenced by exposure to violence, EAC, not knowing they had COVID-19, not knowing the variables that reduced the risk, the physical and psychological domains of the WHOQOL-Bref, not having increased working hours, and not having had COVID-19. The data reveal the multidimensional dynamics of mental health and help understand the relationship between community violence, COVID-19, quality of life, age, and ESF working time with the mental health of ACS.

Resumo: Este artigo avalia as repercussões da pandemia da COVID-19 no cotidiano de trabalho da equipe da Estratégia Saúde da Família (ESF) em diversos municípios do Nordeste brasileiro, na perspectiva dos agentes comunitários de saúde (ACS). Um questionário estruturado foi utilizado para coletar informações sobre a COVID-19, atividades dos ACS e equipes da ESF em 2021. Participaram 1.935 ACS de quatro capitais (Fortaleza - Ceará, João Pessoa - Paraíba, Recife - Pernambuco e Teresina - Piauí) e quatro cidades do interior (Crato, Juazeiro do Norte, Barbalha e Sobral, Ceará). A idade média dos ACS era de 46,25±8,54 anos, sendo a maioria mulheres (82,42%). Muitos (39,92%) estavam infectados com COVID-19, dos quais 70,78% acreditavam ter sido infectados no ambiente de trabalho. Ao todo, 77,82% definiam seu papel como linha de frente no combate à COVID-19, 16,07% relataram receber treinamento para a COVID-19 e 13,74% tinham acesso a equipamentos de proteção suficientes contra a COVID-19. A maioria (90,27%) acredita que suas rotinas de trabalho foram modificadas pela pandemia, fortalecendo o espírito de equipe (41,46%) ou enfraquecendo-o (44,41%). Houve uma redução na promoção da saúde nas escolas (75,66%) e na frequência de visitas domiciliares (60,55%), de grupos específicos na comunidade (93,96%) e outros serviços comunitários locais (66,01%). Nos municípios avaliados, observou-se uma heterogeneidade significativa em relação à resposta à pandemia de COVID-19, possivelmente associada à falta de coordenação do Governo Federal. A pandemia levou a uma reconfiguração dos sistemas locais de saúde, fluxos de trabalho e protocolos de atenção primária para as equipes da ESF. A importância do Sistema Único de Saúde (SUS) e seu potencial de reorganização durante as crises devem ser reconhecidos, preservando-se os avanços alcançados até o momento.

Abstract: This article evaluates the COVID-19 pandemic impacts on the Family Health Strategy (FHS) team’s work routines across a range of northeast Brazilian cities as perceived by community health workers (CHW). Data on COVID-19, CHW activities, and FHS teams were collected in 2021 by a structured questionnaire. A total of 1,935 CHWs from four state capitals (Fortaleza - Ceará State, João Pessoa - Paraíba State, Recife - Pernambuco State, Teresina - Piauí State) and four hinterland cities (Crato, Juazeiro do Norte, Barbalha, Sobral - Ceará State) participated in the study. Most CHWs were women (82.42%), with mean age 46.25±8.54 years. Many (39.92%) were infected with COVID-19, of which 70.78% believed they were infected in the workplace. A total of 77.82% defined their role as frontline in the fight against COVID-19, 16.07% reported receiving training for COVID-19, and 13.74% had access to sufficient protective equipment. Most (90.27%) believed their work routines were modified by the pandemic, either strengthening (41.46%) or weakening (44.41%) the team spirit. Home visits (60.55%), health promotion actions in schools (75.66%) and in specific community groups (93.96%), and other on-site community services (66.01%) showed a reduction in frequency. The sampled cities revealed a significant heterogeneity regarding responses to the COVID-19 pandemic, possibly associated with a lack of coordination by the Federal Government. Regardless of context, the pandemic led to a reconfiguration of local health systems, workflows, and primary care protocols for FHS teams. The importance of the Brazilian Unified National Health System (SUS) and its potential for reorganization during crisis should be acknowledged while preserving the headway made thus far.

Abstract Eugenol is a phenolic compound with numerous biological activities. It is widely used in dentistry to treat toothache and pulpitis. In particular, eugenol may be used for tooth whitening procedures to minimize dental sensitivity in patients. However, eugenol has some disadvantages such as its volatility, its photosensitivity, and immediate effect, which can be avoided by using pharmaceutical nanotechnology. The aim of the present study was to obtain, characterize, quantify, and evaluate the physicochemical stability of eugenol-loaded Eudragit RS100 nanocapsules. The nanocapsules (NCs) were prepared by interfacial deposition of the preformed polymer method. The NCs were characterized through morphological and spectroscopic studies. The encapsulation efficiency was achieved by quantifying the non-encapsulated eugenol using a previously developed and validated analytical method. The physicochemical stability of NCs was assessed at predetermined time intervals for 90 days after preparation. The nanocapsules were successfully prepared by the chosen method and had a predominantly spherical shape with a smooth surface. The mean size, the polydispersion index, and the zeta potential were in agreement to literature data. Infrared spectra ensured that the nanoencapsulation process did not result in chemical reactions between the drug and the polymer. The formulations showed encapsulation efficiency higher than 90% and remained stable after 60 days of preparation. Thus, eugenol-loaded Eudragit RS100 nanocapsules may be further considered as an alternative formulation for dental sensitivity in order to provide a controlled release, a decreased toxicity, and a better dental sensitivity relief.

ABSTRACT Numerous tests employed to predict cardiac and functional status are expensive and not widely accessible for a considerable number of patients, particularly those diagnosed with Chagas disease (CD) residing in remote and endemic regions. To date, there is no knowledge of studies that have validated instruments that address functionality in an expanded way, including the biopsychosocial factors in patients with CD. This study aims to evaluate the psychometric properties of the World Health Organization Disability Assessment Schedule (WHODAS 2.0), in its 12-item shortened version (WHODAS-12) when applied to patients with CD. This is a cross-sectional study of a prospective cohort that follows individuals with CD (SaMi-Trop). Data collection took place between October 2019 and March 2020. In the interviews, sociodemographic information, life habits, clinical information, and indicators of disability measured by WHODAS-12 were collected. Descriptive analysis, internal consistency and construct validity of the instrument were performed. A total of 628 patients with CD were interviewed, most were women (69.5%), their mean age was of 57 years, and most declared an average self-perception of health (43.4%). The 12 items of WHODAS-12 were distributed into three factors, which together account for 61% of the variance. The Kaiser–Meyer–Olkin (KMO) index was 0.90, indicating adequacy of the sample for factor analysis. The internal consistency of the global scale showed alpha = 0.87. The percentage of incapacity was 16.05%, indicating mild incapacity for the evaluated patients. WHODAS-12 is a valid and reliable measure to assess the disability of the Brazilian population with CD.

ABSTRACT Brazil experienced one of the fastest increasing numbers of coronavirus disease (COVID-19) cases worldwide. The Sao Paulo State (SPS) reported a high incidence, particularly in Sao Paulo municipality. This study aimed to identify clusters of incidence and mortality of hospitalized patients with severe acute respiratory syndrome for COVID-19 in the SPS, in 2020–2021, and describe the origin flow pattern of the cases. Cases and mortality risk area clusters were identified through different analyses (spatial clusters, spatio-temporal clusters, and spatial variation in temporal trends) by weighting areas. Ripley’s K12-function verified the spatial dependence between the cases and infrastructure. There were 517,935 reported cases, with 152,128 cases resulting in death. Of the 470,441 patients hospitalized and residing in the SPS, 357,526 remained in the original municipality, while 112,915 did not. Cases and death clusters were identified in the Sao Paulo metropolitan region (SPMR) and Baixada Santista region in the first study period, and in the SPMR and the Campinas, Sao Jose do Rio Preto, Barretos, and Sorocaba municipalities during the second period. We highlight the priority areas for control and surveillance actions for COVID-19, which could lead to better outcomes in future outbreaks.

Abstract Objective To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group.

ABSTRACT Moringa oleifera (Lam.) is an oilseed rich in unsaturated fatty acids. The seed reserve composition can change according to environmental conditions of precipitation and temperature. Thus, this work aimed to characterize the M. oleifera seed and its vegetable oil from plants cultivated in different states of Northeast Brazil. Seeds and soil samples were collected in Bahia (BA), Ceará (CE), Paraíba (PB), and Rio Grande do Norte (RN). Regarding climate variables, RN and BA had the lowest (395 mm) and highest (880 mm) precipitation during the collection year, respectively. The size and mass of the seeds and almonds, and the characterization of the flour and the oil of the ‘moringa’ seeds were measured. The largest seeds and almonds were collected in BA and the smallest in RN. The highest protein and moisture contents were obtained in the seeds from CE. The seeds from RN had the highest oil content, unsaturated fatty acids, ashes, acidity, and saponification levels. Thus, RN presents the smallest seeds of M. oleifera with higher content of mineral salts (ashes), oil, and monounsaturated fatty acids.

RESUMO Moringa oleifera (Lam.) é uma oleaginosa rica em ácidos graxos insaturados. A composição de reserva da semente pode mudar de acordo com as condições ambientais de precipitação e temperatura. Assim, objetivou-se com este trabalho caracterizar sementes e o óleo vegetal de M. oleifera cultivado em diferentes estados do Nordeste do Brasil. As sementes e amostras de solo foram coletadas na Bahia (BA), Ceará (CE), Paraíba (PB) e Rio Grande do Norte (RN). Em relação às variáveis climáticas, RN e BA apresentaram a menor (395 mm) e a maior (880 mm) precipitação durante o ano de coleta. As sementes e amêndoas foram medidas e realizada a caracterização da farinha e do óleo de moringa. As maiores sementes e amêndoas foram coletadas na BA e as menores no RN. O maior teor de proteínas e umidade foram obtidos nas sementes do CE. As sementes do RN apresentaram o maior teor de óleo, níveis de acidez e saponificação e a maior quantidade de ácidos graxos insaturados. Assim, o RN possui as menores sementes de M. oleifera com maior teor de sais minerais, óleo e ácidos graxos monoinsaturados.
