Food and Nutrition Security (SAN) is the realization of everyone's right to access food in sufficient quantities, quality and regularly, without compromising access to other needs. In view of the increase in food and nutrition insecurity, observed in recent years in Brazil and in the world, concomitant with the disruption of programs and public policies combined with the incentive to promote the right to Food and Nutritional Security (SAN) in Brazil (2019-2022) , and the pandemic context that aggravated this problem, we are currently experiencing alarming levels of Food and Nutrition Insecurity (INSAN), including the serious one that is characterized by hunger, which preferentially affects a certain social class and region in Brazil, North and Northeast. The present study analyzed the food and nutritional security profile of families residing in the rural community of Sítio Laguinha, around a wind farm in the municipality of Caetés, in Pernambuco. This study can be characterized as a mixed descriptive study with a quantitative and qualitative approach, in order to identify the prevalence of food (in)security and the associated factors. A semi-structured questionnaire was used to obtain information on socioeconomic conditions and food consumption in the rural community of Laguinha, as well as the Brazilian Food Insecurity Scale (EBIA) to assess the situation of Food and Nutritional Security. Among the factors associated with the community, the vulnerabilities to which this community is exposed stand out, such as the location in a rural area that is difficult to move around, around a wind farm that brings with it impacts and the pandemic context. The results obtained showed a high prevalence of food and nutritional insecurity (88.4%) at all levels, mild, moderate and severe. Among the factors that may be associated with and aggravate the INSAN situation, we can mention the impact of the wind farm and the pandemic, with all associated socioeconomic impacts. The results obtained in this work bring relevant data about the situation of an invisible community that needs assistance to achieve food and nutritional security, a right established in our constitution. In addition, these data can serve as a basis for the implementation of public policies aimed at the community

A Segurança Alimentar e Nutricional (SAN) é a realização do direito de todos ao acesso a alimentos em quantidade suficiente, qualidade e regularmente, sem comprometer o acesso a outras necessidades. Diante do aumento da insegurança alimentar e nutricional, observada nos últimos anos no Brasil e no mundo, concomitante com a desestruturação de programas e políticas públicas aliadas ao incentivo à promoção do direito à Segurança Alimentar e Nutricional (SAN) no Brasil (2019-2022), e o contexto pandêmico que agravou esse problema, atualmente vivenciamos índices alarmantes de Insegurança Alimentar e Nutricional (INSAN), incluindo a insegurança grave que se caracteriza pela fome, que afeta preferencialmente uma determinada classe social e região no Brasil, Norte e Nordeste. O presente estudo analisou o perfil da segurança alimentar e nutricional de famílias residentes na comunidade rural do Sítio Laguinha, em torno de um parque eólico no município de Caetés, em Pernambuco. Esse estudo pode ser caracterizado como descritivo misto com abordagem quantitativa e qualitativa, a fim de identificar a prevalência da (in)segurança alimentar e os fatores que a ela se associam. Foram utilizados um questionário semiestruturado para obtenção de informações sobre condições socioeconômicas e de consumo alimentar da comunidade rural de Laguinha bem como a Escala Brasileira de Insegurança Alimentar (EBIA) para avaliar a situação de Segurança Alimentar e Nutricional. Dentre os fatores associados à comunidade destaca-se as vulnerabilidades às quais essa comunidade está exposta, como a localização em uma área rural de difícil deslocamento, em torno de um parque eólico que traz consigo impactos e o contexto pandêmico. Os resultados obtidos mostraram alta prevalência de insegurança alimentar e nutricional (88,4%) em todos os níveis, leve, moderada e grave. Dentre os fatores que podem estar associados e agravar a situação de INSAN podemos citar o impacto do parque eólico e a pandemia, com todos impactos socioeconômicos associados. Os resultados obtidos neste trabalho trazem dados relevantes sobre a situação de uma comunidade invisibilizada e que necessita de assistência para alcançar a segurança alimentar e nutricional, um direito estabelecido na nossa constituição. Além disso, esses dados podem servir de base para implementação de políticas públicas voltadas à comunidade.

ABSTRACT: This study evaluated the impacts of thermal processing on the chemical composition of jackfruit seeds and their toxicity. The ash content of the seeds subjected to roasting was higher (3.21%) compared to the seeds in the other treatments. However, the contents of moisture (5.29%) and protein (10.49%) were lower. The protein content showed a significant difference (P≤ 0.05) among the studied groups (10.49%). The lipid content was lower in the seeds subjected to cooking (1.13%), while the carbohydrate content showed a significant difference (P≤ 0.05) among the groups studied (54.11%). Raw seeds had the highest fiber content (25.20%). Regarding toxicity, only the cooked jackfruit seed flour showed cytotoxic potential. However, none of the samples caused irritation or vascular disorders in fertilized eggs. These results suggested that heat treatment can ensure the safety of seeds against cytotoxicity; although, it reduces the content of some macronutrients.

RESUMO: Este estudo teve como objetivo avaliar os impactos do processamento térmico na composição química das sementes de jaca sua toxicidade. O teor de cinzas das sementes submetida à torra foi maior (3,21%) em comparação com as sementes nos outros tratamentos. No entanto, os teores de umidade (5,29%) e proteínas (10,49%) foram menores. O teor de proteínas apresentou diferença significativa (P≤ 0.05) entre os grupos estudados (10,49%). O teor de lipídeos foi menor nas sementes submetidas ao cozimento (1,13%), enquanto o teor de carboidratos apresentou diferença significativa (P ≤ 0.05) entre os grupos estudados (54,11%). As sementes brutas apresentaram o maior teor de fibras (25,20%). Em relação à toxicidade, apenas a farinha de sementes de jaca cozidas apresentou potencial citotóxico, embora nenhuma das amostras tenha causado irritação ou distúrbios vasculares em ovos fecundados. Esses resultados sugerem que o tratamento térmico pode garantir a segurança das sementes frente à citotoxicidade, embora reduza o teor de alguns macronutrientes.

Abstract The article brings the results of quantitative-qualitative research of the jurisprudence of the Superior Court of Justice on granting house arrest to pregnant women, mothers, or guardians of children under 12 years old before and during the Covid-19 pandemic, with CNJ Recommendation 62/2020 as a landmark. Through grounded theory, we identified a continuity in the denials of conversions based on “extremely exceptional situations”, linked to the practice of drug trafficking, even in the face of the serious global health crisis of Covid-19.

Resumo O artigo traz os resultados de uma pesquisa quanti-qualitativa da jurisprudência do Superior Tribunal de Justiça sobre a concessão de prisão domiciliar a mulheres gestantes, mães ou responsáveis por crianças menores de 12 anos antes e durante a pandemia da Covid-19, tendo como marco a Recomendação 62/2020 do CNJ. Através da teoria fundamentada nos dados, identificamos uma continuidade nas denegações das conversões com base em “situações excepcionalíssimas”, vinculadas à prática do tráfico de drogas, mesmo diante da grave crise sanitária global da Covid-19.

Abstract Background Pharmacogenetics promises better control of diseases such as cardiovascular disease (CVD). Acetylsalicylic acid, aspirin, prevents the formation of an activating agent of platelet aggregation and vasoconstriction, and it is used to prevent CVD. Nevertheless, patients may have treatment failure due to genetic variants that modify the metabolism of the drug causing aspirin resistance (AR). Objectives To realize a systematic literature review to determine the impact of genetic variants on AR. Methods Articles published in the MEDLINE/PubMed, Cochrane, Scopus, LILACS, and SCIELO databases were systematically screened. A total of 290 articles were identified and 269 articles were excluded because they did not comply with the previously established inclusion criteria. A total of 20 case-control studies and 1 cohort was included. Results The genetic variants rs1126643 (ITGA2), rs3842787 (PTGS1), rs20417 (PTGS2), and rs5918 (ITGB3) were the most studied. As for relevance, of the 64 genetic variants evaluated by the articles, 14 had statistical significance (p< 0.05; 95% confidence interval [CI]) in at least one article. Among them, the following have had unanimous results: rs1371097 (P2RY1), rs1045642 (MDR1), rs1051931 and rs7756935 (PLA2G7), rs2071746 (HO1), rs1131882 and rs4523 (TBXA2R), rs434473 (ALOX12), rs9315042 (ALOX5AP), and rs662 (PON1), while these differ in real interference in AR: rs5918 (ITGB3), rs2243093 (GP1BA), rs1330344 (PTGS1), and rs20417 (PTGS2). As study limitations, we highlight the nonuniform methodologies of the analyzed articles and population differences. Conclusion It is noteworthy that pharmacogenetics is an expanding area. Therefore, further studies are needed to better understand the association between genetic variants and AR.

Resumo Antecedentes A farmacogenética promete melhorar o controle de doenças como as cardiovasculares. O ácido acetilsalicílico, a aspirina, previne a formação de um agente ativador da agregação plaquetária e vasoconstrição e é usado na prevenção de tais doenças. No entanto, os pacientes podem ter falha no tratamento devido a variantes genéticas que modificam o metabolismo da droga causando resistência à aspirina (RA). Objetivos Realizar uma revisão sistemática da literatura para determinar o impacto das variantes genéticas na resistência à aspirina. Métodos Artigos publicados nos bancos de dados MEDLINE/PubMed, Cochrane, Scopus, LILACS e SCIELO foram sistematicamente selecionados. Foram identificados 290 artigos e, destes, 269 artigos foram excluídos por não atenderem aos critérios de inclusão previamente estabelecidos. Um total de 20 estudos caso-controles e 1 coorte foi incluído. Resultados As variantes genéticas rs1126643 (ITGA2), rs3842787 (PTGS1), rs20417 (PTGS2) e rs5918 (ITGB3) foram as mais estudadas. Quanto à relevância, das 64 variantes genéticas avaliadas pelos artigos, 14 tiveram significância estatística (p< 0,05; intervalo de confiança [IC] de 95%) em pelo menos um artigo. Entre eles, os seguintes tiveram resultados unânimes: rs1371097 (P2RY1), rs1045642 (MDR1), rs1051931 e rs7756935 (PLA2G7), rs2071746 (HO1), rs1131882 e rs4523 (TBXA2R), rs434473 (ALOX12), rs9315042 (ALOX5AP) e rs662 (PON1), enquanto estes diferiram na interferência real na RA: rs5918 (ITGB3), rs2243093 (GP1BA), rs1330344 (PTGS1) e rs20417 (PTGS2). Como limitações do estudo, destacam-se as metodologias não uniformes dos artigos analisados e as diferenças populacionais. Conclusão Vale ressaltar que a farmacogenética é uma área em expansão. Portanto, mais estudos são necessários para entender melhor a associação entre variantes genéticas e RA.

Abstract Introduction Aging is a dynamic and progressive process that can be associated with the presence of morbidities, such as chronic diseases, and functional decline, characteristic of sarcopenia, which directly affects the self-perceived health of the older. Objective To test the hypothesis that there is an association between sarcopenia, chronic pain, and perceived health in the older. Methods The study used a quantitative approach and enrolled 43 sarcopenic elderly individuals registered in the University of The Third Age Program (UATI) at Universidade do Estado da Bahia, in Brazil, between November and December 2019. Data included patients’ sociodemographic and anthropometric characteristics, self-reported morbidities, multimorbidity, history of chronic pain and perceived health. The data were subjected to descriptive statistical analyses. Crossing of data was performed using Pearson’s chi-square test, and the correlation coefficient was assessed using Cramer’s Phi and V tests. Results There was an association of sarcopenia with chronic pain (p = 0.027) and with age group (p = 0.016), however not with perceived health (p = 0.09). There was also no association between age range and chronic pain (p > 0.05). Conclusion According to the findings of this study, it can be concluded that sarcopenia is associated with the presence of chronic pain and the age of the elderly, not being associated with the perception of health. However, the age of the elderly was not associated with the presence of chronic pain.

Resumo Introdução O envelhecimento é um processo dinâmico e progressivo que pode estar associado à presença de morbidades, como doenças crônicas, e ao declínio funcional, característico da sarcopenia, que afeta diretamente a autopercepção de saúde do idoso. Objetivo Testar a hipótese de que existe associação entre sarcopenia, dor crônica e percepção de saúde em idosos. Métodos O estudo utilizou uma abordagem quantitativa e envolveu 43 idosos sarcopênicos cadastrados na Universidade Aberta da Terceira Idade (UATI) da Universidade do Estado da Bahia, no Brasil, entre novembro e dezembro de 2019. Dados incluíram características sociodemográficas e antropométricas dos pacientes, morbidades autorreferidas, multimorbidade, história de dor crônica e percepção de saúde. Os dados foram submetidos a análises estatísticas descritivas. O cruzamento dos dados foi feito pelo teste de qui-quadrado de Pearson e o coeficiente de correlação foi avaliado pelos testes Phi e V de Cramer. Resultados Houve associação da sarcopenia com dor crônica (p = 0,027) e com faixa etária (p = 0,016), porém não houve associação com a percepção de saúde (p = 0,09). Também não houve associação entre faixa etária e dor crônica (p > 0,05). Conclusão De acordo com os achados deste estudo, pode-se concluir que a sarcopenia está associada à presença de dor crônica e à idade do idoso, não estando associada à percepção de saúde. No entanto, a idade dos idosos não foi associada à presença de dor crônica.

Abstract Despite its small area, Araçá Bay (AB) holds cultural, historical, and economic value and displays great benthic biodiversity. Thus, it is crucial to monitor its environmental health, including knowing the main groups of phytoplankton and their temporal variability. The shallow waters of Araçá Bay are continuously modified by the complex hydrography of the adjacent São Sebastião channel (SSC), challenging standard experimental designs for phytoplankton collection. Here we report changes in phytoplankton composition at intervals of five to six weeks from September 2013 to August 2014 in both Araçá Bay and SSC. Samples were collected twice daily for three consecutive days to increase taxonomic resolution. Our goal was to provide an inventory of species occurrences to aid future public policies and environmental management of the area. Analyses revealed high species richness and 166 different phytoplankton taxa. Diatoms and dinoflagellates were always numerically dominant, but taxa occurrence changed markedly. Diatoms of the genera Pseudo-nitzschia were abundant during spring and summer concurrently to signatures of South Atlantic Central Water in the SSC, while Thalassiosira occurred when waters displayed relatively lower salinity. The inventory demonstrated several potentially harmful species of microalgae and cyanobacteria, strongly suggesting investments in monitoring programs in this area that currently experience an increase in population.

Resumo Apesar de sua pequena área, a baía do Araçá (AB) possui grande valor cultural, histórico e econômico, e biodiversidade bentônica. Assim, é fundamental monitorar sua saúde ambiental, que inclui conhecer os principais grupos de fitoplâncton e sua variabilidade temporal. As águas rasas da baía do Araçá são continuamente modificadas pela hidrografia complexa do canal de São Sebastião (SSC), desafiando desenhos experimentais convencionais para coleta de fitoplâncton. Aqui relatamos mudanças sazonais na composição do fitoplâncton, em intervalos de 4 a 6 semanas, de setembro de 2013 a agosto de 2014 na baía do Araçá e no SSC, sendo coletadas duas vezes ao dia por três dias consecutivos em cada campanha de amostragem para aumentar a resolução taxonômica. Nosso objetivo foi fornecer um inventário de ocorrência de espécies para auxiliar futuras políticas públicas e gestão ambiental na área. As análises revelaram alta riqueza de espécies e 166 táxons fitoplanctônicos diferentes. Diatomáceas e dinoflagelados foram numericamente dominantes, mas a ocorrência de táxons mudou acentuadamente entre observações. As diatomáceas do gênero Pseudo-nitzschia foram abundantes durante a primavera e o verão concomitantemente às assinaturas da Água Central do Atlântico Sul no CSS, enquanto Thalassiosira ocorreu durante períodos de salinidade relativamente mais baixa. O inventário demonstrou várias espécies potencialmente nocivas de microalgas e cianobactérias, sugerindo fortemente investimentos para programas de monitoramento nesta área que vem registrando aumento populacional contínuo.

Abstract Introduction Burnout syndrome (BS) in healthcare professionals (HCP) has been a major concern, and even more so during the coronavirus disease 2019 (COVID-19) pandemic. The need for adequate tools to assess BS is urgent. The objective of this study was to validate the Brazilian Portuguese version of the Copenhagen Burnout Inventory (CBI) in HCP. Methods The sample comprised 1,054 Brazilian HCP. Data were collected for 1 month (May-2020 to June-2020) using an online self-administered questionnaire. Results All three CBI dimensions demonstrated optimal reliability. All consistency measures attained values > 0.90. Split-half correlation values with Spearman-Brown reliability were higher than 0.8. The parallel analysis suggested two factors: personal burnout (PB) and work-related burnout (WB) items were associated with factor 1, and client-related burnout (CB) items were associated with factor 2. Conclusion Our study corroborates the validity of the Brazilian Portuguese version of the CBI, pointing to a close relation between PB and WB in HCP. A public domain tool with evidence quality to ensure sufficient content validity can aid in burnout evaluation and encourage both expansion of the research field and accurate detection and treatment of this syndrome in Brazilian HCP.

Abstract Measurements of the marine carbonate system on tropical and subtropical continental margins are poorly distributed in space and time, with many uncertainties persisting regarding the role of carbon exchanges at the ocean-atmosphere interface in these areas. To calculate sea-to-air CO 2 fluxes in Marine Ecoregions along the Brazilian continental margin (4°N to 34°S), we used data from the Surface Ocean CO 2 Atlas (SOCAT v2020), collected up to 400 km from the coast, at the surface (5 m), between 1991 and 2018, with the aim of investigating the role of ecoregions as potential sinks or sources of atmospheric CO 2. The temperature and salinity of seawater presented variability in the north-south direction mainly because of the broad latitudinal range, reflecting typical patterns of tropical (T = 27.4°C ±1.49; S = 36.4 ±1.91) and subtropical waters (T = 22.8°C ±3.41; S = 35 ±2.91), in addition to the greater or lesser influence of river inputs in each ecoregion. The pCO 2 values in the surface waters varied from 121.81 (Amazon) to 478.92 μatm (Eastern), differing significantly between ecoregions and showing an expected decadal increasing trend, both in the atmosphere and in the seawater. The calculated values of CO 2 fluxes showed non-homogeneous spatio-temporal variations, from -24.37 mmol m-2 d-1 (Rio Grande) to 9.87 mmol m- 2 d-1 (Southeastern). Throughout the analyzed time series, we observed that the Northeast, Amazon and Eastern ecoregions acted predominantly as sources of CO 2 and the Southeastern ecoregions and, mainly, Rio Grande, acted predominantly as sinks of atmospheric CO 2.

ABSTRACT Objective: This study investigates persistent symptoms, health satisfaction, and general quality of life of COVID-19 survivors at 30, 90, and 180 days after Intensive Care Unit discharge. Method: A multicentric prospective cohort study of COVID-19 survivors discharged from eight hospitals in Curitiba - Paraná (Brazil) between September 2020 and January 2022. Eligible COVID-19 survivors were interviewed by phone. A descriptive analysis was performed, and data were compared using Cochran’s Q test and Friedman’s nonparametric test. Results: Sixty-two COVID-19 survivors responded to the three interview moments. The most persistent symptoms were fatigue, mild dyspnea, and myalgia. At 30, 90, and 180 follow-up days, most patients reported “good” general quality of life (59.7%, 62.9%, 51.6%, respectively) and a “satisfactory” health state (43.5%, 48.4%, 46.8%, respectively). Conclusion: This study revealed the persistence of symptoms after COVID-19 infection; understanding these consequences is the first step towards developing medical treatments and management strategies for these patients.

Understanding the impact of political and institutional factors on the fight against climate change has become increasingly important in the global debate on sustainability. From a political science perspective, it is crucial to research how different democratic institutions affect the development of climate policies. To contribute to this agenda, we discuss the role of participatory institutions in this policy sector. We offer a global literature review of cases where participatory mechanisms have helped improve the tools used to combat global warming. Next, we discuss the concept of climate denialism and examine the environmental policy of the Jair Bolsonaro administration in Brazil (2019-2022) and the dismantling of participatory bodies. This neoconservative government is an example of how limiting civil society's ability to oversee and regulate government policies helps to promote a climate denialist agenda. Finally, we conclude that enhancing participatory democracy is essential to improving climate change policies. However, this relationship also operates in reverse. Disrupting participatory mechanisms can be highly damaging to good environmental governance, paving the way for denialist projects.

ABSTRACT Recent investigations highlight the importance of the gut microbiota and bacteria-derived metabolites as key components in obesity and metabolic health. The microbiota-gut-brain axis presents promising targets for future obesity treatments and prevention. However, the current state of evidence and existing clinical applications of the microbiota-gut-brain axis have yet to be summarized in a thorough review. Therefore, we sought to examine current evidence on the effect of lifestyle, dietary, pharmacological, and surgical interventions on the microbiota-gut-brain axis. In addition, this review highlights potential next steps in research toward characterizing the role of the microbiota-gut-brain axis in metabolic health, along with possible interventions to address obesity.

RESUMO Introdução A terminologia para disfunção neurogênica do trato urinário inferior em adultos (DNTUIA) deve ser definida e organizada com base clínica em um relatório de consenso. Métodos Este relatório foi criado por um Grupo de Trabalho sob o endosso e diretrizes do Standardization Steering Committee (SSC) da International Continence Society (ICS), auxiliado em intervalos por julgadores externos. Todas as definições relevantes para DNTUIA foram atualizadas com base em pesquisas nos últimos 14 anos. Um extenso processo de 18 rodadas de revisão interna e externa foi realizado para examinar exaustivamente cada definição, com tomada de decisão pela opinião coletiva (consenso). Resultados O Relatório de Terminologia para a DNTUIA, englobando 97 definições (42 novas e oito modificadas), foi desenvolvido. Este relatório é clinicamente baseado nos diagnósticos definidos mais comuns. Clareza e facilidade de uso têm sido os principais objetivos para torná-lo interpretável por profissionais e pessoas em treinamento em todos os diferentes grupos envolvidos não só na disfunção do trato urinário inferior, mas também em muitas outras especialidades médicas. Conclusão Baseado no consenso, o Relatório de Terminologia para a DNTUIA foi produzido para auxiliar na pesquisa e na prática clínica.

ABSTRACT The importance of amphibian bioacoustics is widely documented in ecological, taxonomical and evolutionary studies, as calls might act as a primary mechanism of reproductive isolation. The influence of air temperature and male size on the variation of the advertisement calls in anurans is widely recognized but still insufficiently analyzed in Brazilian species. Our goals were to (1) describe the advertisement call of Aplastodiscus albosignatus (Lutz & Lutz, 1938), (2) test the influence of temperature and body size on its acoustic signals and (3) evaluate the variation of within and between-male acoustic signals. Advertisement calls of A. albosignatus consist of an unpulsed note with four harmonics. In most cases, the dominant frequency is the third harmonic but, in some calls, it was the minimum frequency (first harmonic). The average duration of calls was 0.191 s, the interval between calls was 2.08 s and the repetition rate was 33 calls per minute. On average, the minimum frequency was 550.15 Hz, the maximum frequency was 3531.70 Hz and the third harmonic was 2498.9 Hz. To evaluate the effect of air temperature, and body size on the variation of call parameters, we performed generalized linear models. The most explanatory model for spectral parameters was temperature plus body size. Concerning temporal variables, the best model that explains the variation in call duration was body size, while for the interval between calls was air temperature. The maximum frequency and the frequency of the third harmonic had little variation in the calls of both the same male and different males. Thus, these parameters were considered important in species recognition.

Abstract Our objective was to describe and compare the diet of endemic anurans of the Atlantic Forest, as well as to evaluate the influence of biotic factors on the trophic ecology of the species. We conducted the study in Mananciais da Serra (Piraquara-PR), a transition region between mixed and dense ombrophilous forest, between January 2019 and February 2020. In this work, we describe the diet of eight species: Aplastodiscus albosignatus, Boana semiguttata, Bokermannohyla circumdata, Ischnocnema henselii, Leptodactylus notoaktites, Proceratophrys boiei, Rhinella abei and Scythrophrys sawayae. Coleoptera were important prey in the diet of most species, except for B. circumdata and L. notoaktites. All species showed potential selection for some category of prey. We observed a correlation between the size of the individuals and the volume of consumed prey in I. henselii. In general, the niche overlap between species was low, and most species had a broad trophic niche.
