Abstract Roadkill is one of the most direct impacts on fauna, leading to numerous direct and indirect impacts. Road-killed animals could serve as a resource for research and teaching purposes, but first, they need to have their tissues preserved by some technique. Plastination is one of the most modern techniques for the conservation of biological tissues, its principle is the replacement of body fluids by a curable polymer, resulting in a non-toxic, odorless, and manipulable material. So the main aim of this work was to compose a collection of plastinated roadkill victims from the Biological Reserve Sooretama region, adapting the standard protocol to the different taxa worked here (Avialae, Reptilia, Amphibia, and Mammalia). For this, 42 animals were used, previously frozen and stored in the Sooretama Biological Reserve and Vale Natural Reserve until they were sent for processing. Upon arriving at the Plastination laboratory at the Federal University of Espírito Santo, the animals underwent the 4 stages of plastination: fixation, dehydration, forced impregnation, and chemical cure; some adaptations were made to improve the final specimens. The results proved that the plastination of these animals is extremely viable in generating satisfactory results. Given the results obtained, it becomes clear how plastination can become an alternative to implement in the composition of biological collections using roadkill animals. The animals prepared in this work comprise an unprecedented collection available for different applications, such as exhibitions, practical classes, and research.

Abstract The present study aimed to investigate the association between racial iniquities and oral health status. This is a systematic review with a protocol registered on the Prospero Platform (CRD42021228417), with searches carried out in electronic databases and in gray literature. Our study identified 3,028 publications. After applying the eligibility criteria and risk of bias analysis, 18 studies were selected. The results indicate that individuals of black/brown race/skin color have unfavorable oral health conditions, mainly represented by self-rated oral health, tooth loss, caries, and periodontitis. The results showed racial iniquities in oral health in different countries, for all analyzed indicators, with a greater vulnerability of the black population.

ABSTRACT Management of Quilombola systems are primitive agricultural systems based on the ancestral knowledge of Afro-Brazilian enslaved people. Here, the aim was to understand the impact of these primitive farming methods on the distribution of available nitrogen (N) forms in the soil profile of two Brazilian Cerrado phytophysiognomies. The soil was sampled in Cerradão (high Cerrado) and Cerrado Stricto sensu (low Cerrado) at six soil depths (0-10, 10-20, 20-30, 30-40, 40-50, and 50-60 cm). The following management systems were considered: pasture (PP1 and PP2), maize cultivation (M1 and M2), citrus-cassava intercropping (T1), and citrus monoculture (T2). In addition, the soil was sampled in the native area of Cerradão (NC1) and Cerrado Stricto sensu (NC2). Three N forms were determined: i) available nitrogen (Av-N), ii) ammonium (NH4+-N) and iii) nitrate (NO3–-N) contents. The Av-N content decreased with increasing soil depth only in NC1 and NC2. The NO3–-N content was similar at all soil depths for maize and pasture, while the content decreased at soil depth for NC1, NC2, and T1. NH4+-N was similar in M2 and PP2, but it increased in T2, ranging from 6.17 mg kg–1 to 17.54 mg kg–1. Overall, the dynamics of available N forms varied according to the Cerrado phytophysiognomy and the management systems and NO3–-N was the most constant N form in the soil profile. Therefore, although the management of Quilombola systems is less intensive, they negatively affect the dynamics and N availability, mainly where management is less conservative, that is, in maize and citrus monocultures.

ABSTRACT Agroecological management is considered a model of sustainable agriculture that offers social, environmental and economic benefits. The hypotheses of this study were that agroecological production systems can promote changes in the physical fractions of soil organic matter (SOM) associated with aggregates of different origins, and that the greater diversity of plant species in the production system may favour an increase in the carbon concentration of these aggregates. The aim of this study was to a) determine the mass of the free light fraction (FLF), intra-aggregate light fraction (ILF) and light organic matter fraction (LOM) of biogenic and physiogenic soil aggregates; and b) quantify the organic carbon content of the three light SOM fractions and the residual particulate SOM fraction. Five production systems were evaluated: AgF - Agroforestry system; CSun - Coffee grown in full sun; CSha - Coffee grown in shade; FLE - Flemingia grown in alleys; and NT - No-tillage. The aggregates were separated, identified and classified according to their origin or formation pathway into biogenic (formed by biological processes) or physiogenic aggregates (resulting from chemical and physical actions). From these, the mass and carbon content of the FLF, ILF, LOM and residual particulate fractions were quantified. The greater diversity of plant species found in the AgF system has not yet favoured an increase in the carbon content of the aggregates. The longer set-up time and the management practices of the CSun system has led to an increase in the carbon content of the organic fractions of the aggregates (3.44-1.63 g kg-1 for C-LOM; 1.93-1.13 g kg-1 for C-FLF). The lowest overall mean values for LOM and ILF were found mainly in the aggregates of the NT system (1.22-1.67 and 1.55-2.20 g kg-1, respectively), being associated with the shorter time and greater mobilisation of the arable layer. Biogenic aggregation afforded the highest overall mean values for LOM, and increased the mass of the light fractions (15.5%-27.8% for FLF; 23.4%-8.0% for ILF) and the carbon in the C-LOM, C-FLF and residual particulate fractions (42.3%, 12.9%, and 35.0%, respectively) in the surface layer, suggesting an improvement in soil quality.

Resumen: Brasil tiene una alta morbimortalidad materna y perinatal. Los casos de morbilidad materna severa, maternal near miss y muertes perinatales son importantes indicadores de salud y comparten los mismos determinantes sociales, y tienen una estrecha relación con las condiciones de vida y la calidad de la asistencia perinatal. Este artículo pretende presentar el protocolo de estudio que tiene como objetivo estimar la tasa de mortalidad perinatal y la incidencia de morbilidad materna severa y maternal near miss en el país, así como identificar sus determinantes. Se trata de un estudio transversal integrado a la investigación Nacer en Brasil II, realizada entre el 2021 y el 2023. Este estudio incluirá 155 maternidades públicas, mixtas y privadas, con más de 2.750 partos al año, que participan en el Nacer en Brasil II. En estas maternidades, se realizará una recopilación retrospectiva de datos de las historias clínicas maternas y neonatales de todas las hospitalizaciones ocurridas en un período de 30 días, con la aplicación de un formulario de triaje para identificar casos de morbilidad materna y de muerte perinatal. Los datos de las historias clínicas de todos los casos identificados se recopilarán tras el alta hospitalaria, mediante un instrumento estandarizado. Los casos de morbilidad materna severa y maternal near miss se clasificarán por medio de la definición adoptada por la Organización Mundial de la Salud. Se estimará la tasa de mortalidad perinatal y la incidencia de morbilidad materna severa y maternal near miss. Los casos se compararán con los controles obtenidos en el estudio Nacer en Brasil II, emparejados por hospital y duración del embarazo, para identificar factores asociados con desenlaces negativos. Se espera que los resultados de este artículo contribuyan al conocimiento sobre la morbilidad materna y la mortalidad perinatal en el país, así como a la elaboración de estrategias para mejorar el cuidado.

Abstract: Brazil presents high maternal and perinatal morbidity and mortality. Cases of severe maternal morbidity, maternal near miss, and perinatal deaths are important health indicators and share the same determinants, being closely related to living conditions and quality of perinatal care. This article aims to present the study protocol to estimate the perinatal mortality rate and the incidence of severe maternal morbidity and maternal near miss in the country, identifying its determinants. Cross-sectional study integrated into the research Birth in Brazil II, conducted from 2021 to 2023. This study will include 155 public, mixed and private maternities, accounting for more than 2,750 births per year, participating in the Birth in Brazil II survey. We will collect retrospective data from maternal and neonatal records of all hospitalizations within a 30-day period in these maternities, applying a screening form to identify cases of maternal morbidity and perinatal deaths. Medical record data of all identified cases will be collected after hospital discharge, using a standardized instrument. Cases of severe maternal morbidity and maternal near miss will be classified based on the definition adopted by the World Health Organization. The perinatal deaths rate and the incidence of severe maternal morbidity and maternal near miss will be estimated. Cases will be compared to controls obtained in the Birth in Brazil II survey, matched by hospital and duration of pregnancy, in order to identify factors associated with negative outcomes. Results are expected to contribute to the knowledge on maternal morbidity and perinatal deaths in Brazil, as well as the development of strategies to improve care.

Resumen: El embarazo, el parto y el nacimiento son momentos de grandes cambios en la vida de madres y padres. Este artículo tiene como objetivo presentar el protocolo de investigación para estimar la prevalencia de los resultados de la salud mental en madres y padres en el posparto, maltratos y la satisfacción durante la atención del parto/aborto, y las interrelaciones entre ellos y los factores socioeconómicos, obstétricos y de salud infantil. La investigación tiene dos componentes: un estudio de cohorte prospectivo con todas las puérperas entrevistadas en las 465 maternidades incluidas en la línea de base de la encuesta Nacer en Brasil II realizada entre 2021 y 2023, y un estudio seccional con las parejas/padres de los bebés. Las entrevistas se efectúan mediante llamada telefónica o enlace de autocumplimentación enviado vía WhatsApp a las puérperas a los 2 y 4 meses después del parto/aborto. El contacto con la pareja se hace a los tres meses del nacimiento (excluyendo abortos, mortinatos y muertes de recién nacidos), a través del teléfono facilitado por la puérpera en la sala de maternidad. Las entrevistas abordan, entre las puérperas, los síntomas de depresión, ansiedad y trastorno de estrés postraumático, maltrato durante la atención en la maternidad y la calidad del vínculo madre-bebé. También se investiga la presencia de morbilidad materna y neonatal, uso de servicios posnatales y satisfacción con la atención en la maternidad. Entre los padres, se aborda la ocurrencia de síntomas de depresión y ansiedad, y la calidad de la relación con la esposa/pareja y el bebé. La información recopilada en esta etapa de la investigación puede apoyar la planificación y mejora de la atención dirigida a la salud de la tríada madre-padre-hijo después del nacimiento.

Resumo: A gravidez, o parto e o nascimento são momentos de grandes mudanças na vida das mães e dos pais. Este artigo tem como objetivo apresentar o protocolo da pesquisa para estimar a prevalência dos desfechos em saúde mental nas mães e pais no pós-parto, dos maus tratos e satisfação na atenção ao parto/abortamento, e as inter-relações entre eles e fatores socioeconômicos, obstétricos e da saúde da criança. A pesquisa tem dois componentes: estudo de coorte prospectiva com todas as puérperas entrevistadas nas 465 maternidades incluídas na linha de base da pesquisa Nascer no Brasil II realizada entre 2021 e 2023, e estudo seccional com os companheiros/pais dos bebês. As entrevistas são realizadas por ligação telefônica ou link de autopreenchimento enviado por WhatsApp com as puérperas aos 2 e 4 meses após o parto/aborto. Os companheiros são abordados três meses após o nascimento (excluídos os abortos, natimortos e neomortos), a partir do telefone informado pela puérpera na maternidade. As entrevistas abordam, entre as puérperas, sintomas de depressão, ansiedade e transtorno de estresse pós-traumático, maus-tratos na atenção na maternidade e qualidade do vínculo mãe-bebê. São investigados também a presença de morbidade materna e neonatal, utilização de serviços pós-natais, e satisfação com o atendimento na maternidade. Entre os pais, é abordada a ocorrência de sintomas de depressão e ansiedade, e a qualidade do relacionamento com a esposa/companheira e o bebê. As informações coletadas nessa etapa da pesquisa poderão subsidiar o planejamento e melhoria do cuidado voltado para a saúde da tríade mãe-pai-filho após o nascimento.

Abstract: Pregnancy, parturition and birth bring major changes to the lives of mothers and fathers. This article presents a research protocol for estimating the prevalence of postpartum mental health outcomes in mothers and fathers, abuse and satisfaction in delivery/abortion care, and the correlations between them and socioeconomic, obstetric, and child health factors. As a 2-component research, it consists of a prospective cohort study with all postpartum women interviewed in the 465 maternity hospitals included at the Birth in Brazil II baseline survey conducted from 2021 to 2023, and a cross-sectional study with the newborns’ fathers/partners. Interviews will be conducted via telephone or self-completion link sent by WhatsApp with the mother at 2 and 4 months after delivery/abortion. Partners will be approached three months after birth (excluding abortions, stillbirths and newborn death) using the telephone number informed by the mother at the maternity ward. Postpartum women will be inquired about symptoms of depression, anxiety and post-traumatic stress disorder, abuse during maternity care and quality of the mother-newborn bond. Maternal and neonatal morbidity, use of postnatal services, and satisfaction with maternity care are also investigated. Fathers will be asked to report on symptoms of depression and anxiety, and the quality of the relationship with the partner and the newborn. The information collected in this research stage may help to plan and improve care aimed at the postpartum health of the mother-father-child triad.

Abstract: The Maternal Mortality Study conducts a hospital investigation of maternal deaths that occurred in 2020/2021 in the maternity hospitals sampled by the Birth in Brazil II survey, with the following objectives: estimate the maternal mortality underreporting; calculate a correction factor and the corrected (MMR); validate the causes of maternal mortality reported in the death certificate (DC); and analyze the factors associated with maternal mortality. The Birth in Brazil II includes approximately 24,250 puerperal women distributed in 465 public, private, and mixed hospitals with ≥ 100 live births/year in the five macroregions of Brazil. The Maternal Mortality Study data will be completed using the same Birth in Brazil II questionnaire, from the consultation of hospital records. Trained obstetricians will fill out a new DC (redone DC) from independent analysis of this questionnaire, comparing it to official data. The database of the investigated deaths will be related to the deaths listed in the Mortality Information System of the Brazilian Ministry of Health, allowing the estimation of underreporting and calculation of the corrected MMR. To calculate the reliability of the causes of death, the kappa test and prevalence-adjusted kappa with 95% confidence interval will be used. A case-control study to estimate the risk factors for maternal mortality will be developed with the investigated deaths (cases) and the controls obtained in the Birth in Brazil II survey, using conditional multiple logistic regression models. We expect this research to contribute to the correction of the underreporting of maternal mortality and to a better understanding of the determinants of the persistence of a high MMR in Brazil.

Resumen: El Estudio de Mortalidad Materna evalúa las muertes maternas ocurridas en 2020-2021 en las muestras de maternidades del encuesta Nacer en Brasil II con los objetivos de estimar el subregistro de mortalidad materna y calcular el factor de corrección y la tasa de mortalidad materna corregida (TMM); validar las causas de mortalidad materna reportadas en el certificado de defunción (CD); y analizar los factores asociados a la mortalidad materna. La Nacer en Brasil II incluye aproximadamente 24.250 mujeres puerperales, distribuidas en 465 hospitales públicos, privados y mixtos con ≥ 100 nacidos vivos/año en las cinco macrorregiones de Brasil. Los datos de Estudio de Mortalidad Materna se completarán con la información del cuestionario Nacer en Brasil II a partir de una búsqueda de los registros médicos hospitalarios. Los obstetras capacitados completarán un nuevo CD (CD rehecho) desde un análisis independiente de este cuestionario, comparándolo con los datos oficiales. La base de datos de muertes investigadas se relacionará con las muertes que constan en el Sistema de Informaciones sobre la Mortalidad del Ministerio de Salud para permitir la estimación del subregistro y el cálculo de la TMM corregida. Para calcular la exactitud de las causas de muerte, se utilizarán las pruebas kappa y kappa ajustada a la prevalencia con un intervalo de 95% de confianza. Un estudio de casos y controles se aplicará para estimar los factores de riesgo de las mortalidad materna con las muertes investigadas (casos) y los controles obtenidos en el estudio Nacer en Brasil II utilizando modelos de regresión logística múltiple condicional. Se espera que este estudio pueda contribuir a la corrección del subregistro de la mortalidad materna y a una mejor comprensión de los determinantes de la persistencia de alta TMM en Brasil.

Resumo: O Estudo da Mortalidade Materna conduz uma investigação hospitalar dos óbitos maternos ocorridos em 2020/2021 nas maternidades amostradas na pesquisa Nascer no Brasil II, com os seguintes objetivos: estimar o sub-registro da mortalidade materna e calcular um fator de correção e a razão de mortalidade materna (RMM) corrigida; validar as causas de mortalidade materna informadas na declaração de óbito (DO); e analisar os fatores associados à mortalidade materna. O Nascer no Brasil II inclui aproximadamente 24.255 puérperas distribuídas em 465 hospitais públicos, privados e mistos com ≥ 100 partos de nascidos vivos/ano nas cinco macrorregiões do país. Os dados do Estudo da Mortalidade Materna serão preenchidos utilizando o mesmo questionário do Nascer no Brasil II, a partir da consulta aos prontuários hospitalares. Obstetras treinados preencherão uma nova DO (DO refeita) a partir de análise independente desse questionário, comparando aos dados oficiais. A base de dados dos óbitos investigados será relacionada com os óbitos constantes no Sistema de Informações sobre Mortalidade do Ministério da Saúde, permitindo a estimativa do sub-registro e cálculo da RMM corrigida. Para o cálculo da confiabilidade das causas de morte, serão utilizados os testes kappa e kappa ajustado à prevalência com intervalo de 95% de confiança. Um estudo de caso-controle para estimar os fatores de risco para mortalidade materna será desenvolvido com os óbitos investigados (casos) e os controles obtidos na pesquisa Nascer no Brasil II, utilizando-se modelos de regressão logística múltipla condicional. Espera-se contribuir para a correção do sub-registro da mortalidade materna e para a melhor compreensão dos fatores determinantes da persistência de RMM elevada no Brasil.

Resumen: Aunque Brasil ha presentado avances en la atención obstétrica en hospitales públicos y privados, todavía hay puntos débiles que necesitan atención. El Ministerio de Salud, consciente de esta necesidad, financió la segunda versión de la encuesta Nacer en Brasil. Los objetivos generales son: evaluar la atención prenatal, el parto y el nacimiento, el puerperio y el aborto, comparando con los resultados del Nacer en Brasil I, y analizar los principales determinantes de la morbimortalidad perinatal; evaluar la estructura y los procesos de atención de los servicios de obstetricia y neonatología en las maternidades; analizar los conocimientos, prácticas y actitudes de los profesionales de la salud que brindan atención para el parto y el aborto; e identificar las principales barreras y facilitadores para esta atención en el país. Tiene un alcance nacional y muestra probabilística en dos etapas (1-hospitales y 2-mujeres), la cual se dividió en 59 estratos; y se seleccionaron 465 hospitales con un total planificado de aproximadamente 24.255 mujeres, de las cuales 2.205 tuvieron procedimientos por aborto y 22.050 por parto. Para la recolección de datos se aplicó seis instrumentos electrónicos, que se realizó durante la hospitalización por parto o aborto, con dos rondas de seguimiento, a los dos y cuatro meses. Con el fin de ampliar el número de casos de morbilidad materna grave, mortalidad materna y perinatal, se incorporaron tres estudios de casos y controles en Nacer en Brasil II. El trabajo de campo comenzó en noviembre de 2021 y finalizará en 2023. Los resultados nos permitirán evaluar la atención al parto y al nacimiento actual con lo que se retrató en la primera encuesta, de esta manera se podrá evaluar los avances alcanzados a lo largo de estos 10 años.

Resumo: Com o passar do tempo, o Brasil vem apresentando avanços na assistência obstétrica em hospitais públicos e privados; no entanto, ainda existem pontos frágeis que necessitam de atenção. O Ministério da Saúde, ciente dessa necessidade, financiou a segunda versão da pesquisa Nascer no Brasil. Os objetivos gerais são: avaliar a assistência pré-natal, ao parto e nascimento, ao puerpério e ao aborto, comparando com os resultados do Nascer no Brasil I, e analisar os principais determinantes da morbimortalidade perinatal; avaliar a estrutura e processos assistenciais dos serviços de obstetrícia e neonatologia das maternidades; analisar os conhecimentos, atitudes e práticas de profissionais de saúde que prestam assistência ao parto e ao aborto; e identificar as principais barreiras e facilitadores para essa assistência no país. Com escopo nacional e amostra probabilística em dois estágios (1-hospitais e 2-mulheres), dividida em 59 estratos, foram selecionados 465 hospitais com total planejado de, aproximadamente, 24.255 mulheres, 2.205 por motivo de aborto e 22.050 por motivo de parto. A coleta de dados, realizada por meio de seis instrumentos eletrônicos, ocorre durante a internação hospitalar para o parto ou aborto, com duas ondas de seguimento, aos dois e quatro meses. Com o intuito de expandir o número de casos de morbidade materna grave, mortalidade materna e perinatal, três estudos caso controle foram incorporados ao Nascer no Brasil II. O trabalho de campo foi iniciado em novembro de 2021 com término previsto para 2023. Os resultados permitirão comparar a atenção atual ao parto e ao nascimento com a retratada no primeiro inquérito e, com isso, avaliar os avanços alcançados no decorrer desses 10 anos.

Abstract: Brazil has made advances in obstetric care in public and private hospitals; however, weaknesses in this system still require attention. The Brazilian Ministry of Health, aware of this need, funded the second version of the Birth in Brazil survey. This study aimed to evaluate: prenatal, labor and birth, postpartum, and abortion care, comparing the results with those of Birth in Brazil I; and analyze the main determinants of perinatal morbidity and mortality; evaluate the care structure and processes of obstetrics and neonatology services in maternity hospitals; analyze the knowledge, practices, and attitudes of health professionals who provide birth and abortion care; and identify the main barriers and facilitators related to care of this nature in Brazil. With a national scope and a 2-stage probability sample: 1-hospitals and 2-women, stratified into 59 strata, 465 hospitals were selected with a total planned sample of around 24,255 women - 2,205 for abortion reasons and 22,050 for labor reasons. Data collection was conducted using six electronic instruments during hospital admission for labor or abortion, with two follow-up waves, at two and four months. In order to expand the number of cases of severe maternal morbidity, maternal and perinatal mortality, three case control studies were incorporated into Birth in Brazil II. The fieldwork began in November 2021 and is scheduled to end in 2023. It will allow a comparison between current labor and birth care results and those obtained in the first study and will evaluate the advances achieved in 10 years.

Abstract Over the last three decades, stroke care has undergone significant transformations mainly driven by the introduction of reperfusion therapy and the organization of systems of care. Patients receiving treatment through a well-structured stroke service have a much higher chance of favorable outcomes, thereby decreasing both disability and mortality. In this article, we reviewed the scientific evidence for stroke reperfusion therapy, including thrombolysis and thrombectomy, and its implementation in the public health system in Brazil.

Resumo Nas últimas três décadas, o tratamento do AVC sofreu transformações significativas, impulsionadas principalmente pela introdução das terapias de reperfusão e pela organização dos serviços de AVC. Os pacientes que recebem tratamento em um serviço de AVC bem estruturado têm uma probabilidade muito maior de resultados favoráveis, diminuindo assim a incapacidade funcional e a mortalidade. Neste artigo, revisamos as evidências científicas para as terapias de reperfusão do AVC, incluindo trombólise e trombectomia e sua implementação no sistema público de saúde no Brasil.

Abstract During the 1980s and 1990s there was an expansion of interest in the symbolic dimensions of social movements. As a result, more interpretative analytical models were developed. Some of the most important of these are the study of emotions and frame analysis. This article presents the basic assumptions that support these theoretical perspectives as analytical tools; there is a special interest in the study of emotions because it is more recent and less developed approach. The article argues that, although structural and cultural perspectives are not necessarily mutually exclusive, the assumption of culture and the world of meanings as secondary elements for the explanation of the origin, development and end of social movements must be avoided.

Resumen Durante las décadas de 1980 y 1990 se dio una expansión en el interés de las dimensiones simbólicas de los movimientos sociales, como resultado, se desarrollaron modelos analíticos de corte más interpretativo. Algunos de los más importantes son el estudio de las emociones y el análisis de marcos. En el presente artículo se presentan los supuestos básicos que sostienen estas perspectivas teóricas como herramientas de análisis; hay un especial interés en el estudio de las emociones debido a que se trata de un enfoque más reciente y se encuentra menos desarrollado. El artículo argumenta que, aunque las perspectivas estructurales y culturales no son necesariamente excluyentes entre sí, es necesario evadir el presupuesto de la cultura y el mundo de los significados como elementos secundarios para la explicación del origen, desarrollo y fin de los movimientos sociales.

ABSTRACT Overcoming malnutrition in all its forms, which is also manifested in the obesity epidemic, is one of the priorities of the 2030 Agenda and the Sustainable Development Goals. This article presents reflections on food insecurity in Brazil, based on topics such as population growth, climate change, biodiversity and traditional and regenerative food systems; it also addresses the role of social initiatives to guarantee the Human Right to Adequate Food. The Nutrition and Poverty Research Group, Planetary Health - Brazil Group, and the Center for Artificial Intelligence (C4AI) - AgriBio Axis, assume that the organized and systemic resumption of the initiatives mentioned out in this position paper can contribute to the articulation between research, public policies and services, to combat all forms of malnutrition, as a complex and priority problem to ensure social welfare.

RESUMO O combate à má alimentação em todas as suas formas, que também se expressa na epidemia da obesidade, é uma das prioridades da Agenda 2030 e dos Objetivos de Desenvolvimento Sustentável. Este artigo traz elementos sobre insegurança alimentar no Brasil, a partir de temas relativos ao crescimento populacional, mudanças climáticas, biodiversidade e sistemas alimentares tradicionais e regenerativos; trata também do papel dos movimentos sociais para a garantia do Direito Humano à Alimentação Adequada. O Grupo de Pesquisa em Nutrição e Pobreza, o Saúde Planetária Brasil, e o Centro de Inteligência Artificial (C4AI) - Eixo AgriBio, entendem que a retomada organizada e sistêmica das frentes apontadas neste artigo de posicionamento, pode constituir um caminho para a articulação entre pesquisa, serviço e políticas públicas na direção do combate à fome e às demais manifestações da má alimentação, enquanto problema complexo prioritário para a garantia do bem-estar social.

Abstract The demographic transition process has generated questions about population aging, as well as drawing the attention of international organizations and public policy managers to generate programs that address this reality. The older adults, as a new social protagonist, questions the need to go through a “successful aging process”. In this way, educational opportunities become liberating options for this group, helping them to remain active, productive, and inserted in society. This work aimed to map the occurrence of educational policies, through the textual analysis of legal frameworks and formal documents related to the Elderly and Education in Brazil. As a result, the generic orientation of the Ministry of Education in relation to the group of older adults was observed, since the educational premises of the National Education Plan only mention Youth and Adults. This is evidenced by the lack of a coherent didactic project aimed specifically at the group. The negative image of the elderly in Brazil, who lost their role after so many years of illiteracy, can be institutionalized.

Resumen El proceso de transición demográfica ha generado interrogantes sobre el envejecimiento poblacional, así como llamar la atención de organismos internacionales y gestores de políticas públicas para generar programas que aborden esta realidad. La persona mayor, como nuevo protagonista social, pone en entredicho la necesidad de transitar por un “proceso de envejecimiento exitoso”. De esta manera, las oportunidades educativas se convierten en opciones liberadoras para este grupo, ayudándolos a mantenerse activos, productivos e insertos en la sociedad. Este trabajo tuvo como objetivo mapear la ocurrencia de las políticas educativas a través del análisis textual de marcos legales y documentos formales relacionados con las personas mayores y la educación en Brasil. Como resultado, se observó la orientación genérica del Ministerio de Educación en relación con el grupo de adultos mayores, ya que las premisas educativas del Plan Nacional de Educación solo mencionan jóvenes y adultos. Con esto se evidencia la falta de un proyecto didáctico coherente dirigido específicamente a las personas mayores. La imagen negativa de los adultos mayores en Brasil, que perdieron su protagonismo después de tantos años de analfabetismo, puede ser institucionalizada.

Abstract Objective: To identify the perceptions of implementing online cooperative learning during the 2021 II academic semester by first-year students of Universidad Nacional Mayor de San Marcos (UNMSM) School of Medicine. Materials and methods: A descriptive and cross-sectional research design was used in this study. The population consisted of 592 students from the professional schools of Human Medicine, Nursing, Obstetrics, Nutrition and Medical Technology. A random probability sampling was carried out and a sample of 429 students was obtained. The Cooperative Learning Questionnaire with an 8-point Likert scale response format developed by McLeish was used as an instrument for data collection. It is a reliable and valid instrument that was administered online to the sample of students at the end of the course using Google Forms. The quantitative data were analyzed descriptively using IBM SPSS Statistics V22. The descriptive statistics included frequencies, averages and standard deviation. Results: Out of the students in the sample, 65.9 % were females and 34.1 % were males. Most participants had favorable perceptions of online cooperative learning, with averages between 3.77 and 4.53. Favorable perceptions of this methodology were mainly identified in the dimensions quality of the group interaction process, teaching of interpersonal skills in small groups and positive interdependence. Conclusions: The students had favorable perceptions of online cooperative learning because it helped them to improve their social skills, favored their attitude toward group work, allowed them to participate in the sessions with enthusiasm, helped them to improve peer interaction, and promoted the development of their creativity and interpersonal skills. Therefore, its implementation and analysis of achievements in online environments are recommended.

Resumen Este artículo introductorio al dossier temático trae a colación nuevos planteamientos en cuanto a la mirada que tenemos sobre las diásporas negras y con respecto a los marcos conceptuales y empíricos de los estudios sobre las movilidades. Está dividido en tres partes. En la primera, abordamos la teoría reciente sobre las diásporas, así como su historicidad, espacialidades y diversidades aplicadas al Atlántico negro. En la segunda, repasamos el debate académico en torno a las (in)movilidades en trayectorias extendidas como las registradas en los textos del dossier. Luego, nos acercamos a las geografías reconfiguradas por el paso y la instalación de personas negras en el continente americano. En la tercera parte, proponemos una sistematización en dos niveles: la contribución del dossier a los estudios sobre las movilidades y diásporas negras en las Américas y las líneas temáticas trabajadas. Por último, presentamos sucintamente cada uno de los textos. partes primera historicidad negro segunda inmovilidades in Luego americano parte niveles trabajadas último

Abstract This introductory paper to the dossier brings up new approaches to black diasporas and to the conceptual and empirical frameworks of mobility studies. It is divided into three parts. In the first, we address recent theory on diaspora, as well as the historicity, spatialities and diversities as applied to the Black Atlantic. In the second, we review the scholarship in the field of (im)mobilities in extended trajectories such as those examined in the dossier. Then, we approach the geographies reconfigured by the transit and settlement of Black people in the Americas. In the third part, we propose a systematization on two levels: the contribution of the dossier to studies on Black mobilities and diasporas, and the thematic lines explored. Finally, we briefly present each paper. parts first diaspora historicity Atlantic second immobilities im Then Americas part levels explored Finally

Abstract A strong brand has been identified as a long-term success factor. Still, there is a gap in the perception of different types of fans about the brand equity dimensions of football teams and how their dimensions influence loyalty in the Brazilian context. The purpose of the present study was to analyse the perception of brand equity among members and non-members of football teams and its influence on behavioural intentions. Data were collected from 420 fans of a State Football Championship from Brazil through an online survey and analysed using multigroup structural equation modelling. In that context, the brand mark was not an association considered by the fans, and the analysis indicated a better perception of the brand equity dimensions by the members, and the analysis with the complete sample indicated the relevance of the model (R2= 77%). Specifically, internalisation, social interaction, and management dimensions significantly impacted the behavioural intentions of football fans. The study provides an understanding of the dimensions of brand equity in a context not previously studied and the different perceptions of these dimensions through multigroup analysis. Further, it informs marketers of the brand equity elements that must be taken into account in an attempt to leverage team behavioural intentions.
