Resumo O objetivo deste artigo é analisar os níveis de resiliência, depressão e autoeficácia entre profissionais de enfermagem brasileiros na pandemia de COVID-19. Estudo transversal analítico realizado entre os meses de outubro e dezembro de 2020. Foram empregados o teste T de Student, a análise de variância e a regressão linear múltipla com o objetivo de investigar em que medida os dois grandes fatores (resiliência e autoeficácia) impactavam nos níveis de depressão. Participaram do estudo 8.792 profissionais de enfermagem, 5.124 (58,8%) tiveram baixos níveis de resiliência. A média da pontuação geral para “depressão” foi de 0,74 e variou de 0,59 a 0,80. A média da pontuação geral para “autoeficácia” foi de 0,68 e variou de 0,56 a 0,80. Quanto aos preditores de depressão, a variável que mais fortemente impactou os níveis de depressão foi resiliência, explicando 6,6% do desfecho (p < 0,001, R2 Ajustado = 0,066). Os participantes deste estudo tiveram, em geral, baixos níveis de resiliência e autoeficácia e maiores pontuações médias para depressão. Os níveis de resiliência impactaram a variável depressão. Urge a necessidade de ações voltadas para a promoção da saúde psicológica de profissionais de enfermagem inseridos em contextos pandêmicos.

Abstract This aim of this study was to analyze levels of resilience, depression and self-efficacy among Brazilian nursing professionals during the COVID-19 pandemic. We conducted an analytical cross-sectional study between October and December 2020. Student’s t test, analysis of variance and multiple linear regression were used to investigate the impact of two main factors (Resilience and Self-efficacy) on depression. A total of 8,792 nursing professionals participated in the study; 5,124 (58.8%) had low levels of resilience. The mean overall score for Depression was 0.74, ranging from 0.59 to 0.80, while the mean overall score for Self-efficacy was 0.68, ranging from 0.56 to 0.80. The variable that had the strongest impact on depression levels was Resilience, explaining 6.6% of the outcome (p < 0.001, AdjustedR2 = 0.066). In general, respondents had low levels of resilience and self-efficacy and showed high mean depression scores. Level of resilience had an impact on depression. The findings reveal an urgent need for actions to promote the psychological health of nursing professionals working in crisis situations such as pandemics.

Resumo Introdução: Os produtos de tabaco aquecido (HTP) têm ganhado popularidade nos últimos anos. No entanto, tem-se questionado sobre os danos que provocam na saúde, em especial aos impactos decorrentes da exposição a suas emissões. O objetivo deste estudo é avaliar o impacto do uso de HTPs em ambientes internos/fechados na qualidade do ar e/ou na saúde das pessoas expostas passivamente, por meio de uma revisão sistemática de estudos originais. Métodos: Realizou-se busca bibliográfica nas bases de dados Medical Literature Analysis and Retrieval Sistem (MEDLINE), Excerpta Medica Database (EMBASE), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e SCOPUS. As etapas de seleção, extração dos dados e avaliação do risco de viés dos estudos foi realizada em dupla, de forma independente, e as divergências foram resolvidas por consenso. Resultados: Foram selecionados 21 estudos, incluídos nesta revisão. Os resultados indicam que os produtos de tabaco aquecido são fonte de poluição ambiental decorrente da emissão de material particulado. Conclusão: Os produtos de tabaco aquecido produzem emissões que podem expor as pessoas às substâncias tóxicas emitidas no ambiente fechado, assim como outros produtos de tabaco.

Abstract Introduction: Heated tobacco products (HTP) have gained popularity in recent years. However, questions have been raised about the damage they cause to health, especially the impacts resulting from exposure to their emissions. This study aims to evaluate the impact of the use of HTPs indoors on air quality and/or the health of passively exposed people, through a systematic review of original studies. Methods: A bibliographic search was carried out in the Medical Literature Analysis and Retrieval System (MEDLINE), Excerpta Medica Database (EMBASE), Latin American and Caribbean Health Sciences (LILACS) and SCOPUS databases. Results: 21 studies were selected and included in this review. The results indicate that heated tobacco products are a source of environmental pollution due to the emission of particulate matter. The stages of selection, data extraction and risk of bias assessment of the studies were performed in pairs, independently, and disagreements were resolved by consensus. Conclusion: Heated tobacco products produce emissions that can expose people to toxic substances emitted indoors, just like other tobacco products.

Resumo Investigamos os efeitos da desaceleração econômica do período 2015-2018 sobre a desconcentração territorial da indústria no Brasil, bem como identificamos quais estruturas setoriais são territorialmente reforçadas ou enfraquecidas. As indústrias geradoras de mais alto valor agregado, produtividade e salários, que nas últimas três décadas têm reduzido participação na estrutura produtiva brasileira, foram ainda mais negativamente impactadas na recessão recente. As conclusões apontam para o reforço de um padrão de desconcentração espúria, no qual porções desenvolvidas e industrializadas do território e com maior geração de valor agregado são mais afetadas – perderam mais empregos industriais e mais salários – que as áreas especializadas em commodities agrominerais caracterizadas por baixos níveis de produtividade e valor agregado.

Abstract We investigated how the economic slowdown of the 2015-2018 period affected the territorial deconcentration of the Brazilian industry, as well as which sectoral structures are territorially strengthened or weakened. Industries with higher added value, productivity and wages, which have reduced participation in the Brazilian production structure in the last three decades, were even more negatively impacted in the recent recession. The conclusions point to the strengthening of a pattern of spurious deconcentration in which the developed and industrialized areas of the territory are more affected—they have lost more jobs and wages—than those specialized in agromineral commodities.

Abstract This systematic review aimed to investigate the effect of physical activity on anxiety symptoms during the COVID-19 pandemic. Three databases (PubMed; Scopus and Web of Science) were searched in the period from 2020 to 2022 the following base terms were used: “Physical Activity”, Exercise, Anxiety and COVID-19. Peer-reviewed, primary studies published in English, Portuguese and Spanish using valid and reliable measures were included. Eighteen studies met the eligibility criteria, of which 17 were cross-sectional, 2 were cohort studies. The number of participants ranged from 43 to 2,301, aged between 18 and 65 years or older. A decrease in PA practice or an increase in sitting time were associated with higher levels of anxiety symptoms. Additionally, participants who did not meet PA recommendations were more likely to experience moderate to severe anxiety symptoms. The results showed that physical activity is associated with the alleviation of anxiety symptoms during confinement in the COVID-19 pandemic.

Resumo Esta revisão sistemática teve como objetivo investigar o efeito da atividade física nos sintomas de ansiedade durante a pandemia de COVID-19. Foram pesquisadas três bases de dados (PubMed; Scopus e Web of Science) no período de 2020 a 2022 foram utilizados os seguintes termos base: “Physical Activity”, Exercise, Anxiety e COVID-19. Foram incluídos estudos primários, revisados por pares, publicados em inglês, português e espanhol usando medidas válidas e confiáveis. Dezoito estudos preencheram os critérios de elegibilidade, sendo 17 transversais, 2 estudos de coorte. O número de participantes variou de 43 a 2.301, com idade entre 18 e 65 anos ou mais. Uma diminuição na prática de AF ou um aumento no tempo sentado foram associados a níveis mais elevados de sintomas de ansiedade. Além disso, os participantes que não atendiam às recomendações de AF eram mais propensos a apresentar sintomas de ansiedade moderados a graves. Os resultados mostraram que a atividade física está associada ao alívio dos sintomas de ansiedade durante o confinamento na pandemia de COVID-19.

ABSTRACT: White Mold (WM) is a yield–limiting disease found in soybean. However, up to now no cultivars have been genetically resistant to this disease. Given this context, the present study aimed to develop superior soybean lines with resistance to WM, while maintaining other desirable agronomic traits. Two early maturing soybean cultivars (i.e., EMGOPA 316 and MG/BR 46–Conquista), moderately resistant to WM were used for biparental crosses from which the analyzed population was derived. Therefore, we assessed the resistance to WM in early generation testing of this population. Additionally, we determined the agronomic traits, genetic parameters and selection gains. From 348 F2 genotypes, 35 transgressive genotypes moderately resistant to WM were identified, amongst which 22 genotypes showed desirable agronomic traits for early cycle and grain yield. Moreover, 69 lines were selected as the most promising genotypes for each agronomic trait (i.e. based on the number of days to flowering and maturity, plant height at flowering and maturity, number of nodes on main stem at flowering and maturity, number of pods, grain yield, etc.). Among these selected lines, ten progenies emerged as the superior genotypes for grain yield and early cycle. All together, these results demonstrated that the cross between EMGOPA 316 × MG/BR 46 (Conquista) revealed promising progenies with moderate resistance to WM and/or desirable agronomic traits. Thus, these lines could be used as future resources for breeding efforts aimed at improving resistance to WM.

Abstract Persea americana Mill., belonging to the family Lauraceae, is noteworthy for the large amount of ethnopharmacological information in its regard, attributing to it many and varied medicinal properties. The tea and alcoholic extracts made from its leaves are used in folk medicine to treat various ailments. This study was designed to analyze the cytogenotoxicity and underlying chemistry of aqueous and hydroalcoholic extracts of avocado leaves, using the Allium cepa and micronucleus tests. The results obtained by applying the experimental models demonstrate that the extracts did not have a genotoxic effect at any of the concentrations analyzed, and even demonstrated a certain protective effect, possibly due to the presence of flavonoids and phenols, both of which are antioxidant substances. However, the extracts did present a cytotoxic effect. There were numerous karyorrhectic cells and those with nuclear alterations related to cell death. At the highest concentrations, it was possible to observe cytoplasmic alterations and binucleated cells. The extracts also caused a significant reduction in the number of cells undergoing division. These effects can be a response to the phytochemical agents present in the extracts. The results suggest that the extracts contain bioactive components that deserve further studies related to cancer therapies.

RESUMO Objetivo: Comparar a confiabilidade interobservador da mensuração da morfologia do psoas e lordose lombar nas diferentes posições e padronizar a realização do exame de ressonância magnética em posição prona e lateral. Métodos: Trata-se de um estudo transversal realizado com voluntários assintomáticos de ambos os sexos, maiores de 18 anos, sem alterações patológicas conhecidas na região lombar. Foi realizada ressonância magnética da coluna lombar na posição supina, decúbito lateral direito e prono, obtendo imagens nas sequências ponderadas em T2 nos planos sagital e axial. Foram medidas as distâncias do psoas até o platô vertebral e o plexo lombar. Os exames foram avaliados por dois ortopedistas independentes em caráter cego. Resultados: Houve ótima concordância entre as medições do tamanho da vértebra (ICC=0.92), baixa concordância para a distância do plexo (ICC = 0,63) e alta concordância para a margem anterior (ICC = 0,84). Conclusão: Houve boa reprodutibilidade das medidas propostas, sugerindo que a técnica em posição lateral e prona é capaz de gerar imagens de qualidade. Nível de Evidência 3B; Prospectivo.

ABSTRACT Objective: To compare the interobserver reliability of measurements of psoas morphology and lumbar lordosis in different positions and to standardize the performance of magnetic resonance imaging in the prone and lateral positions. Methods: This is a cross-sectional study carried out with asymptomatic volunteers of both sexes, aged over 18 years, with no known pathological changes in the lumbar region. Magnetic resonance imaging of the lumbar spine was performed in the supine, right lateral decubitus and prone positions, obtaining images in T2-weighted sequences in the sagittal and axial planes. The distances were measured from the psoas to the vertebral plateau and from the psoas to the lumbar plexus. The exams were assessed by two independent, blinded orthopedists. Results: There was excellent agreement between the measurements of vertebral size (ICC=0.92), low agreement for plexus distance (ICC=0.63) and high agreement for the anterior margin (ICC=0.84). Conclusion: There was good reproducibility of 2 of the 3 measures proposed, suggesting that the technique in the lateral and prone positions is capable of generating quality images. Level of Evidence 3B; Prospective.

Abstract Paper aims This paper analyzes Command and Control (C2) Systems and identifies the level of knowledge on the subject by actors involved in disaster response operations in Brazil, besides assessing the evolution in this area since the disaster of the Serrana Region of Rio de Janeiro in 2011. Originality The concept of C2 is still little explored academically, especially in disaster management systems. This study contributes to the understanding of the dynamics of different C2 Systems operated in Brazil, as well as identifying the level of knowledge on the subject and its evolution since 2011. Research method This is an exploratory survey in which data was analyzed using descriptive statistics techniques. Main findings We conclude that the actors involved in real disaster situations have little formal training in C2. The findings indicate that the performance of a simulated exercise helps in disaster preparedness, but the participants observed deficiencies concerning C2 training besides the lack of local community involvement in the simulated exercise. Implications for theory and practice This study contributes to the disaster management literature, showing empirical evidence that the results obtained in a simulated exercise can boost the specialization of professionals in C2 systems in the area of disasters.

Abstract Bauhinia forficata Link is widely used in Brazilian folk medicine to treat several pathologies. Commercial and botanically identified samples were evaluated via a gas chromatography equipped with a flame ionization detector and a gas chromatography-mass spectrometer. This procedure allowed the identification of 116 compounds, representing 72% to 96% of the total content of the investigated essential oils. The five samples analyzed showed yields of essential oil ranged from 0.03 to 0.10%, being sesquiterpenes and oxygenated sesquiterpenes the major components. Hierarchical Cluster Analysis and Principal Component Analysis were used in order to demonstrate variations in the essential oils’ composition of B. forficata and were able to clusterize these samples in three groups based on relationships and chemical patterns in essential oils. In natura samples showed to be different from commercial samples and CS3 group was the most distinct group of the commercial samples. In spite of differences among samples, it is concluded that essential oils of B. forficata presented a rich composition, presenting 11 compounds in common between them, which could be possible to establish a set of compounds as chemical markers for the species, still non-existent in literature.
