Resumo Objetivou-se analisar a associação entre o reconhecimento de uma fonte usual do cuidado de Atenção Primária à Saúde (APS) e o acesso aos serviços de APS, entre adolescentes brasileiros. Estudo transversal, a partir da Pesquisa Nacional de Saúde do Escolar realizada com 68.968 adolescentes brasileiros, através de amostragem por conglomerados. Foram realizadas análises descritivas através do χ2 de Pearson e a razão de prevalência (RP) através dos modelos de regressão logística entre acesso aos serviços de APS e o reconhecimento da FUC APS. Dos adolescentes que procuraram os serviços de APS, 74,6% referiram acesso, sendo a maior do sexo feminino (79,3%). Na análise multivariada, observa-se associação positiva (RP: 1,25; IC95%: 1,24-1,26), e na estratificado por sexo, observou-se associações positivas para ambos os sexos, (RP: 1,30; IC95%: 1,28-1,31) masculino e (RP: 1,21; IC95%: 1,20-1,23) feminino. Verifica-se que a maioria dos adolescentes brasileiros que têm a APS como sua FUC conseguiram acessar os serviços de APS, apesar de que, a falta de acesso foram mais frequentes entre os mais vulneráveis economicamente e devido a comportamentos de risco, indicando iniquidades potencialmente evitáveis por meio de uma APS mais efetiva e longitudinal.

Abstract We analyzed the association between the recognition of a usual source of care (USC) of Primary Health Care (PHC) and access to services among Brazilian adolescents. This is a cross-sectional study using data from the National Adolescent School-based Health Survey with 68,968 Brazilian adolescents and cluster sampling. Descriptive analyses were carried out with Pearson’s χ2 and prevalence ratios (PR) using logistic regression models between access and recognition of USC. It was observed that 74.6% reported access, and this was higher among females (79.3%). In the multivariate analysis, there was a positive association (PR: 1.25; 95%CI: 1.24-1.26); and, when stratified by sex, positive associations for both sexes, (PR: 1.30; 95%CI: 1.28-1.31) male and (PR: 1.21; 95%CI: 1.20-1.23) female. The majority of Brazilian adolescents demonstrated PHC as a USC and were able to access services, but lack of access was more frequent among the most economically vulnerable and those with risk behaviors, indicating potentially avoidable inequities with more equitable and longitudinal PHC services.

Resumo Objetivou-se analisar os fatores demográficos, socioeconômicos, de saúde e comportamentos de risco associados ao reconhecimento de uma Fonte Usual de Cuidados (FUC). Estudo transversal, a partir da Pesquisa Nacional de Saúde do Escolar (2015) realizado com 100.464 adolescentes brasileiros. Realizou-se análises descritivas através do χ2 de Pearson, e a razão de prevalência (RP) através dos modelos de regressão logística no Stata 14 para cada tipo de FUC (APS, Consultório Particular, Hospital e Emergência), estratificado por sexo. O reconhecimento de uma FUC foi referido por 55,5% dos adolescentes, sendo 58,6% do sexo feminino. Na análise multivariada, as variáveis que apresentam desigualdades sociais, econômicas e de comportamento de risco demonstraram associações positivas para a FUC APS, para ambos os sexos. Para os demais tipos de FUC, as características demográficas e socioeconômicas quando associadas apresentaram associações foram negativas. Os resultados deste estudo mostraram que a APS é o serviço com maior reconhecimento dos adolescentes em condições de vulnerabilidade social. O que reforça a necessidade de consolidação da APS a fim de favorecer a atenção à saúde dos adolescentes, no estabelecimento de vínculo e na melhoria do acesso às ações de saúde.

Abstract The present study aimed to analyze the demographic, socioeconomic, and health factors and risk behaviors associated with the recognition of a Usual Source of Care (USC), according to gender. This work was a cross-sectional study, based on the National Survey of School Health (2015), conducted with 100,464 Brazilian adolescents. Descriptive analyses were performed based on Pearson’s χ2, and the prevalence ratio (PR) through logistic regression models in Stata 14 for each type of USC (Primary Health Care (PHC), Private Practice, Hospital, and Emergency), stratified by sex. Recognition of a USC was reported by 55.5% of the adolescents, 58.6% of whom were female. In the multivariate analysis, the variables that present social, economic, and risk behavior inequalities showed positive associations for USC PHC for both genders. For the other types of USC, the demographic and socioeconomic characteristics showed negative associations. The results of this study showed that PHC is the service with the highest recognition among adolescents in conditions of social vulnerability. This reinforces the need to consolidate the PHC in order to favor the health care of adolescents, establishing bonds and improving access to health actions.

Resumo: A recente pandemia de COVID-19 levou muitos países a adotarem políticas emergenciais de transferência de renda como forma de conter a crise econômica e humanitária. Tais iniciativas foram desenvolvidas em um contexto de agudização das desigualdades de gênero, raça, etnia e classe em decorrência de medidas de isolamento físico e social. O artigo analisa, a partir de um estudo exploratório e da chamada avaliação baseada na teoria do programa, as premissas teóricas dos programas Bolsa Família (2003), Auxílio Emergencial (2020) e Auxílio Brasil (2021) e suas respectivas dinâmicas de implementação. Na medida em que os programas de transferência de renda ocupam lugar central na agenda pública contemporânea, conclui-se que a avaliação de limites e avanços, tanto em sua concepção teórica como em relação aos mecanismos disparados em cada contexto, contribui para revelar evidências sobre sua efetividade no enfrentamento das desigualdades duráveis e daquelas que surgem em cenários de emergência sanitária.

Resumen: La reciente pandemia de COVID-19 llevó a muchos países a adoptar políticas de emergencia de transferencias monetarias como una forma de contener la crisis económica y humanitaria. Dichas iniciativas se desarrollaron en un contexto de profundización de las desigualdades de género, raciales, étnicas y de clase como resultado de las medidas de aislamiento físico y social. El artículo analiza, a partir de un estudio exploratorio y de la llamada evaluación basada en la teoría del programa, los supuestos teóricos de los programas Bolsa Familia (2003), Ayuda de Emergencia (2020) y Ayuda Brasil (2021), y sus respectivas dinámicas de implementación. Dado que los programas de transferencias monetarias ocupan un lugar central en la agenda pública contemporánea, se concluye que la valoración de los límites y avances, tanto en su concepción teórica como en relación con los mecanismos desencadenados en cada contexto, ayuda a revelar evidencias sobre su efectividad para enfrentar las desigualdades duraderas y las que surgen en escenarios de emergencia sanitaria.

Abstract: The recent COVID-19 pandemic has led many countries to adopt emergency cash transfer policies as a way to contain the economic and humanitarian crisis. Such initiatives were developed in a context of exacerbated gender, race, ethnicity and class inequalities resulting from physical and social distancing measures. The article analyzes, by means of an exploratory study and the so-called theory-driven evaluation of the program, the theoretical premises of the Brazilian Income Transfer Program (2003), Brazilian Emergency Assistance (2020) and Brazil Assistance (2021) programs, and their corresponding implementation dynamics. As cash transfer programs are given centrality in the contemporary public agenda, the conclusion is that evaluating their limits and advances - as to theoretical conception and mechanisms triggered in each context - contributes to trace evidence about their effectiveness in addressing long-term inequalities and those inequalities that arise in health emergency contexts.

ABSTRACT OBJECTIVE To evaluate the quality of information on gestational syphilis (GS) and congenital syphilis (CS) on the Sistema de Informação de Agravos de Notificação (SINAN-Syphilis Brazil – Notifiable Diseases Information System) by compiling and validating completeness indicators between 2007 and 2018. METHODS Overall, care, and socioeconomic completeness scores were compiled based on selected variables, by using ad hoc weights assigned by experts. The completeness scores were analysed, considering the region and area of residence, the pregnant woman’s race/colour, and the year of case notification. Pearson’s correlation coefficients were used to validate the scores obtained by the weighted average method, compared with the values obtained by principal component analysis (PCA). RESULTS Most selected variables presented a good or excellent degree of completeness for GS and CS, except for clinical classification, pregnant woman’s level of education, partner’s treatment, and child’s race/colour, which were classified as poor or very poor. The overall (89.93% versus 89.69%) and socioeconomic (88.71% versus 88.24%) completeness scores for GS and CS, respectively, were classified as regular, whereas the care score (GS-90.88%, and CS-90.72%) was good, despite improvements over time. Differences in the overall, care and socioeconomic completeness scores according to region, area of residence, and ethnic-racial groups were reported for syphilis notifications. The completeness scores estimated by the weighted average method and PCA showed a strong linear correlation (> 0.90). CONCLUSION The completeness of GS and CS notifications has been improving in recent years, highlighting the variables that form the care score, compared with the socioeconomic scores, despite differences between regions, area of residence, and ethnic-racial groups. The weighted average was a viable methodological alternative easily operationalised to estimate data completeness scores, allowing routine monitoring of the completeness of gestational and congenital syphilis records.

Objectives: Gene-environment interactions increase the risk of psychosis. The objective of this study was to investigate gene-gene and gene-environment interactions in psychosis, including single nucleotide variants (SNVs) of dopamine-2 receptor (D2R), N-methyl-d-aspartate receptor (NMDAR), and cannabinoid receptor type 1 (CB1R), lifetime cannabis use, and childhood trauma. Methods: Twenty-three SNVs of genes encoding D2R (DRD2: rs1799978, rs7131056, rs6275), NMDAR (GRIN1: rs4880213, rs11146020; GRIN2A: rs1420040, rs11866328; GRIN2B: rs890, rs2098469, rs7298664), and CB1R (CNR1: rs806380, rs806379, rs1049353, rs6454674, rs1535255, rs2023239, rs12720071, rs6928499, rs806374, rs7766029, rs806378, rs10485170, rs9450898) were genotyped in 143 first-episode psychosis patients (FEPp) and 286 community-based controls by Illumina HumanCoreExome-24 BeadChip. Gene-gene and gene-environment associations were assessed using nonparametric Multifactor Dimensionality Reduction software. Results: Single-locus analyses among the 23 SNVs for psychosis and gene-gene interactions were not significant (p > 0.05 for all comparisons); however, both environmental risk factors showed an association with psychosis (p < 0.001). Moreover, gene-environment interactions were significant for an SNV in CNR1 and cannabis use. The best-performing model was the combination of CNR1 rs12720071 and lifetime cannabis use (p < 0.001), suggesting an increased risk of psychosis. Conclusion: Our study supports the hypothesis of gene-environment interactions for psychosis involving T-allele carriers of CNR1 SNVs, childhood trauma, and cannabis use.

ABSTRACT Objective: to analyze the spatial distribution of violence against older adults in the Brazilian South region before and in the first year of the COVID-19 pandemic. Method: an ecological study that analyzed reports of violence against older adults between 2019 and 2020, in Southern Brazil. Local empirical Bayesian rates, Moran’s Local Autocorrelation Index and Getis Ord Gi analysis were calculated. Results: there was a reduction in the smoothed rate of violence against older adults. The high-high and hot-spot cities in 2019 became more violent in 2020; and cities with low prevalence became less violent in 2020. The highest COVID-19 fatality rates were also in those cities with the highest violence rates. Conclusion: the data reinforces the complexity of violence and its worsening due to the pandemic. In addition, they contribute to decision-making in Nursing, highlighting the need to encourage new research studies on this theme.

Abstract Background RNA extraction is a step that precedes several molecular techniques. The fibrous tissue, more specifically the dura mater, has several limitations in routine protocols, and lacks optimization protocols to overcome these problems. Objective To test stock reagents and purification kits, optimizing commercial kit protocols for RNA extraction from the dura mater. Methods Dura mater samples were obtained from eight Wistar rats and maintained in two different stabilizers. The samples were purified using four different protocols, and the RNA was evaluated for the yield and purity in NanoDrop 2000 (Thermo Scientific, Wilmington, DE, United States). Beta-actin gene was used for analyzing gene expression, since is one of the most used reference genes. Results The RNA preservation was similar in both stabilizers. The addition of an incubation step prior the purification protocols allowed better tissue digestion and RNA recovery. The RNA purified using the protocols membrane-based showed higher quality than liquid-liquid purification. This impact was observed in the 3-week evaluation using RT-qPCR. Conclusion Stabilizers are efficient for RNA preservation and membrane-based purification protocols are more suitable for RNA recovery from dura mater tissue, allowing the evaluation of gene expression in this type of tissue. Adaptations in the dura mater RNA extraction protocol differ from the pre-established protocols because it takes into account the peculiarity of fibrous tissue and low cellularity. In addition to providing a low-cost mechanism, based on techniques that are part of the laboratory routine, it is possible to improve the quality of the extracted material, ensuring greater efficiency in the use of subsequent techniques.

Resumo Antecedentes A extração de RNA é uma etapa que antecede várias técnicas moleculares. O tecido fibroso, mais especificamente a dura-máter, apresenta várias limitações nos protocolos de rotina e carece de protocolos de otimização para superar estes problemas. Objetivo Testar reagentes de estoque e kits de purificação, otimizando protocolos de kits comerciais para extração de RNA da dura-máter. Métodos Amostras de dura-máter foram obtidas de oito ratos Wistar e mantidas em dois estabilizadores diferentes. As amostras foram purificadas em quatro protocolos diferentes e o RNA foi avaliado quanto ao rendimento e pureza no NanoDrop 2000 (Thermo Scientific, Wilmington, DE, United States). O gene da beta-actina foi utilizado para analisar a expressão gênica, uma vez que é um dos genes de referência mais utilizados. Resultados A preservação do RNA foi semelhante em ambos os estabilizadores. A adição de uma etapa de incubação antes dos protocolos de purificação permitiu uma melhor digestão do tecido e recuperação de RNA. O RNA purificado pelos protocolos baseados em membrana apresentou qualidade superior ao da purificação líquido-líquido. Este impacto foi observado na avaliação de três semanas usando RT-qPCR. Conclusão Os estabilizadores são eficientes para preservação do RNA e os protocolos de purificação baseados em membrana são mais adequados para recuperação de RNA do tecido da dura-máter, permitindo a avaliação da expressão gênica neste tipo de tecido. As adaptações no protocolo de extração de RNA da dura-máter diferem dos protocolos preestabelecidos porque leva em consideração a peculiaridade do tecido fibroso e com baixa celularidade. Além de fornecer um mecanismo de baixo custo, baseado em técnicas que fazem parte da rotina laboratorial, é possível melhorar a qualidade do material extraído, garantindo maior eficácia no uso de técnicas subsequentes.

ABSTRACT Introduction: Systemic Mastocytosis comprises a group of neoplastic diseases characterized by clonal expansion and infiltration of mast cells into several organs. The diagnosis and treatment of this disease may be challenging for non-specialists. Objective: Make suggestions or recommendations in Systemic Mastocytosis based in a panel of Brazilian specialists. Method and results: An online expert panel with 18 multidisciplinary specialists was convened to propose recommendations on the diagnosis and treatment of Systemic Mastocytosis in Brazil. Recommendations were based on discussions of topics and multiple-choice questions and were graded using the Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence Chart. Conclusion: Twenty-two recommendations or suggestions were proposed based on a literature review and graded according to the findings.

ABSTRACT Background: Some studies have suggested the importance of vitamin D [25(OH)D] in malaria clinical practice. The prevalence of 25(OH)D deficiency in the Amazon population is not well known, and there are few studies in patients with malaria. This study aimed to evaluate 25(OH)D serum levels in patients with malaria and determine their relationships with epidemiological, clinical, laboratory, and parasitemia data. Methods: An analytical cross-sectional study of 123 patients with malaria and 122 individuals without malaria was performed in Itaituba, Pará, Brazil, from January 2018 to October 2019, by evaluating sociodemographic, clinical-epidemiological, parasitological, and laboratory data and adopting a 5% significance level. Parametric tests (Student's t-test), non-parametric tests (Mann-Whitney U), and Spearman’s correlation ([rs], for non-parametric variables) were used according to the nature of the distribution of the variables. For the qualitative variables, Pearson's chi-square test, Fisher's exact test, and the G test were used. Spearman's correlation was used to compare the results of the 25(OH)D levels and blood counts performed among patients and the control group. Results: Malaria patients residing in a mining area had 25(OH)D serum levels that were significantly lower than those in the control group residing in the mining area, though both were within normal levels. Red blood cell counts had an inverse correlation with parasitemia (Plasmodium falciparum), and platelet levels had an inverse correlation with parasitemia (Plasmodium vivax). 25(OH)D deficiency was evidenced in Itaituba, in the state of Pará, which is an endemic area of malaria in the Amazon region.

Abstract The combination of flours from cereal and legume results in less caloric products, with high contents of fiber, proteins, ash and antioxidants. Thus, this study aimed at developing muffins made with different proportions of wholemeal rye flour (WRF) and wholemeal common black bean flour (WBF). Physicochemical and physical analyses were performed to characterize starches, flours and the muffins. Sensory analysis was also carried out. WRF had the highest values for L* value, moisture and ash contents, whereas WBF had more proteins and lipids, and heterogeneous particle size distribution. The formulation with the highest acceptability grade with total replacement of whole wheat flour, was that containing 70% WRF and 30% WBF (F2). This sample was characterized as high-quality muffin, chocolate flavor, chocolate odor, light and soft crumb. Its texture was defined as low hardness, chewiness and high cohesiveness. It was concluded that the F2 formulation had a high dietary fiber content (20%), low lipid content (8%), containing 32% resistant starch, 9% protein and 51.43 mg GAE 1001 g-1 of total phenolic content, being considered an excellent nutritional food option.
