RESUMEN La hemodiálisis, junto con la enfermedad renal crónica (ERC), intensifica el proceso inflamatorio y el estrés oxidativo en los pacientes en tratamiento. En este contexto, la suplementación con vitamina E puede mitigar los efectos nocivos resultantes de estos procesos. Esta es una revisión sistemática cuyo objetivo fue evaluar el efecto de la suplementación con vitamina E sobre biomarcadores inflamatorios y estrés oxidativo en pacientes con ERC en hemodiálisis. La revisión se elaboró según la metodología para revisiones sistemáticas y metanálisis (PRISMA) y la búsqueda se realizó en las bases de datos Pubmed, Cochrane Library, Scopus y Web of Science. El riesgo de sesgo de los estudios incluidos se evaluó con la Herramienta Cochrane de Riesgo de Sesgo (Cochrane Risk of Bias Tool). En esta revisión se incluyeron doce estudios desarrollados entre 2006 y 2020. La mayoría (n= 11) utilizó dosis de vitamina E que oscilaban entre 400 UI y 888 UI y el tiempo de suplementación osciló entre 2 semanas y 12 meses. De los 12 artículos incluidos, 25% (n= 3) analizaba la suplementación en biomarcadores inflamatorios, 50% (n= 6) en biomarcadores de estrés oxidativo y 25% (n= 3) en estos parámetros simultáneamente. Se observó un efecto positivo en 58,4% de los estudios (n= 7). Por lo tanto, la suplementación con vitamina E puede ser efectiva para mitigar el proceso inflamatorio y el estrés oxidativo, sin embargo, vale la pena señalar que el efecto depende de la dosis y el tiempo de suplementación.

ABSTRACT Hemodialysis, along with chronic kidney disease (CKD), intensifies the inflammatory process and oxidative stress in patients undergoing treatment. In this context, Vitamin E supplementation can mitigate the deleterious effects resulting from these processes. This is a systematic review whose objective was to evaluate the effect of Vitamin E supplementation on inflammatory biomarkers and oxidative stress in patients with CKD on hemodialysis. This review was prepared according to the methodology for systematic reviews and meta-analyses (PRISMA) and the search was performed in Pubmed, Cochrane Library, Scopus and Web of Science databases. The risk of bias of the included studies was assessed with the Cochrane Risk of Bias Tool. Twelve studies developed between 2006 and 2020 were included in this review. Most of them (n= 11) used vitamin E doses ranging from 400 IU to 888 IU and the supplementation time ranged from 2 weeks to 12 months. Of all the 12 articles included, 25% (n= 3) analyzed supplementation on biomarkers of oxidative stress and 25% (n= 3) addressed these parameters simultaneously. A positive effect was observed in 58.4% of the studies (n= 7). Thus, Vitamin E supplementation can be effective in mitigating the inflammatory process and oxidative stress, however, it is worth noting that the effect depends on the dose and time of supplementation.

SUMMARY OBJECTIVE: The aim of this study was to compare the capacity of American Thyroid Association and Thyroid Imaging Reporting and Data System developed by the American College of Radiology in predicting malignancy risk of thyroid nodules and to verify which one is better at avoiding unnecessary fine needle aspiration. METHODS: This was a cross-sectional study with 565 thyroid nodules, followed at a tertiary care hospital, in an iodine-replete area. Those were classified as American Thyroid Association and Thyroid Imaging Reporting and Data System developed by the American College of Radiology systems and stratified according to the Bethesda classification of fine needle aspiration. The values of sensibility, specificity, positive predictive value, and negative predictive value accuracy were calculated. Also, the percentage of unnecessary biopsies was presented. RESULTS: The mean age of the individuals was 58.2±13.5 [26–90] years for benign nodules and 41.7±15.6 [23–66] years for malignant nodules (p=0.002). Regarding gender, 92.6% (n=150) of the individuals with benign nodules and 85.7% (n=06) with malignant nodules were females (p=0.601). For American Thyroid Association, 90.9% of sensibility, 51.4% of specificity, 52.6% of accuracy, 10.2% of positive predictive value, and 98.9% of negative predictive value were found. For Thyroid Imaging Reporting and Data System developed by the American College of Radiology, 90.9% of sensibility, 49.7% of specificity, 52.1% of accuracy, 9.9% of positive predictive value, and 98.9% of negative predictive value were found. .Notably, 12.3% of unnecessary fine needle aspiration were found in American Thyroid Association and 44.4% were found in Thyroid Imaging Reporting and Data System developed by the American College of Radiology. CONCLUSION: Both Thyroid Imaging Reporting and Data System developed by the American College of Radiology and American Thyroid Association are able to predict the malignancy risk of thyroid nodules. Thyroid Imaging Reporting and Data System developed by the American College of Radiology was better at avoiding unnecessary fine needle aspiration.

Abstract The study addresses patent granting in public higher education institutions in Minas Gerais, focusing on deposits made by Technology Innovation Centers (TICs). The aim is to analyze patent applications, including grants, rejections, and the presence of frugal innovation in technologies. The research employs operational logic, deductive methods, and a qualitative approach to gather institution- related information and conduct the analysis. The primary goal is to examine patent application submissions made by these institutions in the state, regardless of the final patent grant outcome. Furthermore, it was possible to detect that the State University of Minas Gerais has 1218 patents filed with the INPI, being ahead of other public institutions in Minas Gerais regarding patents granted. UFLA had the higher number of patent applications rejected, and the UFSJ's TIC had the higher number of patents filed with a bias towards frugal innovation.

ABSTRACT Entomopathogenic fungi stand out in the biological control of several agriculturally important insects. Six isolates of Metarhizium anisopliae, Cordyceps javanica, Beauveria sp. and B. bassiana were screened to control Anthonomus grandis, Euschistus heros, Oebalus poecilus, O. ypsilongriseus and Thyanta perditor, important insect pests of soybean, cotton and rice. The bioassays were conducted in a completely randomized design, with four replications (10 insects/replication). Significant differences for virulence were observed between the tested fungal species and isolates. For A. grandis, the most virulent isolate was M. anisopliae BRM 2335, followed by Beauveria BRM 14527 and BRM 67744 [82.5 to 97.5 % of mortality; average lethal time (LT50) of 5.9 to 7.8 days]. M. anisopliae BRM 2335 was also highly virulent to the four stink bug species (75 to 97.5 % of mortality; LT50 of 5.2 to 9.7 days). For the stink bugs, Beauveria sp. BRM 67744 was infectious to O. poecilus (75 % of mortality), but failed to control E. heros (16.9 % of mortality). C. javanica BRM 27666 and BRM 14526 showed average virulence to the stink bugs and A. grandis (17.5 to 57.3 % of mortality; LT50 of 6.0 to 9.7 days). M. anisopliae was consistently more virulent to the stink bugs than the other fungi. Therefore, M. anisopliae BRM 2335 was selected for further studies under screenhouse and field conditions to control A. grandis and other stink bug species, especially E. heros.

RESUMO Os fungos entomopatogênicos destacam-se no controle biológico de diversos insetos de importância agrícola. Seis isolados de Metarhizium anisopliae, Cordyceps javanica, Beauveria sp. e B. bassiana foram selecionados para o controle de Anthonomus grandis, Euschistus heros, Oebalus poecilus, O. ypsilongriseus e Thyanta perditor, importantes insetos-pragas da soja, algodão e arroz. Os bioensaios foram conduzidos em delineamento inteiramente casualizado, com quatro repetições (10 insetos/repetição). Foram observadas diferenças significativas, em termos de virulência, entre as espécies fúngicas e isolados testados. Para A. grandis, M. anisopliae BRM 2335 foi o isolado mais virulento, seguido por Beauveria BRM 14527 e BRM 67744 [82,5 a 97,5 % de mortalidade; tempo letal médio (TL50) de 5,9 a 7,8 dias]. M. anisopliae BRM 2335 também foi altamente virulento para as quatro espécies de percevejo (75 a 97,5 % de mortalidade; TL50 de 5,2 a 9,7 dias). Para os percevejos, Beauveria sp. BRM 67744 foi infeccioso para O. poecilus (75 % de mortalidade), mas falhou no controle de E. heros (16,9 % de mortalidade). C. javanica BRM 27666 e BRM 14526 apresentaram virulência mediana para os percevejos e A. grandis (17,5 a 57,3 % de mortalidade; TL50 de 6,0 a 9,7 dias). M. anisopliae foi consistentemente mais virulento aos percevejos do que os outros fungos. Portanto, M. anisopliae BRM 2335 foi selecionado para estudos posteriores em casa telada e campo para o controle de A. grandis e outras espécies de percevejo, principalmente E. heros.

Abstract Carioca grains are the most cultivated commercial group of common bean and Fusarium oxysporum f. sp. phaseoli (Fop) is an important disease under field conditions. Genetic resistance is the most effective control strategy. Thus, our objective was to study the inheritance of Fop resistance in the carioca grain type common bean. Lines CNFC 11965 (S) and CVIII 8511 (R) were crossed to obtain F1 and F2 generations and backcrosses, inoculated with the isolate FOP UFV 01, and severity grades used to estimate genetic parameters. Segregation of resistant and susceptible plants in the F2 generations and backcrosses resulted in dominant monogenic inheritance of Fop resistance. The high values of heritability emphasized the probability of success in the selection processes because environmental factors were not significant. The carioca grain line CVIII 8511 is promising, and its Fop resistance gene can be transferred to commercial cultivars of this group using the backcross method.

ABSTRACT. Cotton (Gossypium hirsutum L.) is the world’s leading natural textile fibre and is grown in over 60 countries, including Brazil, where it is an important agricultural commodity. The cultivation area currently covers approximately one million hectares in Brazil and has expanded into every region of the country, especially the Cerrado biome. Because of this expansion, it is necessary to analyse the influence of the environment on the genotype behaviour to optimize yields. Thus, the objective of this study was to compare fuzzy logic to traditional methods for selecting coloured-fibre cotton genotypes with high adaptability and yield stability. The experiment was conducted on the 2013/2014, 2014/2015, 2015/2016, and 2016/2017 crops of the Capim Branco farm at the Federal University of Uberlândia, Uberlândia, Minas Gerais, Brazil. The following methods were used to select genotypes for adaptability and stability: the Lin and Binns model, additive main effects and multiplicative interaction (AMMI) analysis and the Sugeno fuzzy logic controller. An interaction of the genotype with the environment that affected yield was detected. Environment 4 (the 2016/2017 crop) showed to the lowest genotype to environment interaction. The fuzzy logic approach showed agreement with AMMI and the nonparametric Lin and Binns method. The linguistic fuzzy logic used in the Sugeno fuzzy logic controller demonstrated the potential for selecting cotton genotypes in plant breeding programmes. The UFUJP-16 and UFUPJ-17 genotypes were adaptable, stable and showed promising yields within the tested environments. The fuzzy logic method was effective for estimating adaptability and stability.

ABSTRACT This study proposes to update knowledge about the relationship between microbiota and Colorectal Cancer (CRC). This is a review carried out using the methodology of the Preferred Report Item for Systematic Analysis and Meta-Analysis (PRISMA) and search for original articles, indexed in the Pubmed, Cochrane and Science Direct databases, published between 2011 and 2019, in English. Ten articles showed changes in bacterial composition and its influence on the development and progression of CRC, and only two addressed changes in the composition of fungi and their relationship with CRC. Most studies have shown that the increase in Fusobacterium nucleatum and bacteroides fragilis is strongly associated with the occurrence of CRC due to inflammatory mechanisms; and that Faecalibacterium prausnitzii is a protective factor through the production of butyrate. Additional research is recommended to assess the relationship of microorganisms with the development of CRC, with an emphasis on fungi.

RESUMEN Este estudio propone actualizar el conocimiento sobre la relación entre la microbiota y el Cancer Colorectal (CCR). Esta es una revisión realizada utilizando la metodología del Elemento de Informe Preferido para el Análisis Sistemático y el Meta-análises (PRISMA) y la búsqueda de artículos originales, indexados en las bases de datos Pubmed, Cochrane y Science Direct, publicados entre 2011 y 2019, en inglés. Diez artículos mostraron cambios en la composición bacteriana y su influencia en el desarrollo y la progresión del CCR, y solo dos abordaron los cambios en la composición de los hongos y su relación con el CCR. La mayoría de los estudios han demostrado que el aumento de Fusobacterium nucleatum y bacteroides fragilis está fuertemente asociado con la aparición de CCR debido a mecanismos inflamatorios; y que Faecalibacterium prausnitzii es un factor protector a través de la producción de butirato. Se recomienda investigación adicional para evaluar la relación de los microorganismos con el desarrollo de CCR, con énfasis en los hongos.

ABSTRACT A better understanding of genetic diversity in cotton cultivars is needed to make the most of the genetic resources and guarantee continuing improvements in the breeding programs. Our objective was to evaluate the genetic diversity among cotton genotypes from the top breeding programs in Brazil and recommend hybrid combinations that would increase variability. The field experiments we conducted on three cotton genotypes from each of the following Brazilian breeding programs: EMBRAPA, MONSANTO DELTAPINE, FIBERMAX, IMA, TMG and UFU. Several phenotypic evaluations were carried out at V5, B1, full flower and full maturity. Moderate genetic divergence was observed among the genotypes from these breeding programs. Hybridization of the BRS 433 FL B2RF and FM 980 GLT genotypes would likely produce segregating populations with greater genetic variability, yield potential, lint yield and desirable fiber quality. Maturity, micronaire and fiber length were the strongest contributors to genetic divergence.

Abstract Aims: The purpose of this study is to assess the prevalence of oral and dentoalveolar trauma among contact sports practitioners in the Federal District of Brazil. Methods: A cross-sectional descriptive study was conducted using a questionnaire developed specifically for this research regarding the occurrence of facial trauma, site of injuries, how they occurred, the approach is taken to solve the problem, and the use of several types of mouthguards. Data were analyzed using the SPSS 20.0 software, and the chi-square test (X2) was chosen to examine the differences between categorical variables. The results were considered statistically significant for p<0.05. Results: A total of 141 athletes were interviewed, with a prevalence of facial trauma of 65.2%, which was higher in professional athletes (71.1%). Lesions ranged from soft tissue lacerations to combined trauma; and the most frequent injuries were soft tissue laceration (53.3%), combined trauma (16.3%), and dental fracture (9.8%). Only 20.6% of the participants required treatment for related injuries. Regarding the use of mouthguards, 34% of the athletes reported regular use of this device, and Type II mouthguard was the most used (39.7%). Dentists participate in the process of production and dissemination of mouthguards in 17.1% and 10.5% of cases, respectively. Conclusion: The data showed that most athletes are not aware of the importance of using mouthguards. The dentist must be more present in the area of sports dentistry, both for awareness and production of these devices, which support the safe practice of contact sports.

Conclusão a análise das crenças permitiu a elucidação daquelas que podem influenciar positiva ou negativamente o comportamento “tomar os comprimidos prescritos para o controle da hipertensão”, alvo de diferentes intervenções em serviços de saúde.

RESUMO A indústria de base florestal é relevante para a economia mundial, pois seus produtos primários e secundários são usados como matéria-prima para outros setores e serviços gerando emprego e renda para a população e tributos para o Estado. No Brasil, a indústria florestal se destaca pela riqueza em madeira, porém, gera elevada quantidade de resíduos. O objetivo do trabalho foi avaliar a quantidade e os fatores responsáveis pela produção de resíduos madeireiros das indústrias de base florestal da Região Metropolitana de Belém, Pará. Para tanto, foram consideradas um universo de 120 empresas que realizavam o processamento primário e secundário, bem como movelarias. Os dados foram coletados por meio de entrevistas semiestruturadas aplicadas em uma amostra de 31 empresas e observações in loco. As variáveis foram analisadas através da estatística descritiva e correlação de Pearson. Verificou-se que as empresas geraram um total de 12,3 mil m3/mês, com média de 398,9 m3/mês de resíduo. O número de espécies madeireiras influenciou na quantidade de resíduos. Conclui-se, que a partir da comparação com outras pesquisas com esse mesmo tema, que as empresas geram quantidade significativa de resíduo em consequência do número de espécies processadas.

ABSTRACT The forest based industry is relevant to the world’s economy, since its primary and secondary products are used as raw material for other sectors and services generating employment and income for the population and taxes for the state. In Brazil, the forest industry stands out for the wealth of wood, but it generates a high amount of waste. The objective of this study was to evaluate the quantity and the factors responsible for the production of wood residues from the forest-based industries of the metropolitan region of Belém, Pará state. For this purpose, a total of 120 companies were considered that carried out primary and secondary processing, as well as furniture. The data were collected through semi-structured interviews applied in a sample of 31 companies and observations in loco. The variables were analyzed through descriptive statistics and Pearson correlation. It was verified that the companies generated a total of 12.3 thousand m3/month, with a mean of 398.9 m3/month of waste. The number of timber species influenced the amount of waste. It can be concluded from the comparison with other researches with this same theme that the companies generate a significant amount of waste as a consequence of the number of species processed.

Resumo: O objetivo deste trabalho foi avaliar a eficácia dos métodos “straw test” e imersão em ácido oxálico na identificação dos níveis de resistência do algodoeiro (Gossypium hirsutum) branco e colorido ao mofo-branco (Sclerotinia sclerotiorum). Foram avaliados dez genótipos: cinco de fibra colorida, quatro de fibra branca e um genótipo suscetível de fibra branca. Os genótipos MAB-1 de fibra branca e MAC-2 de fibra colorida foram os mais resistentes ao mofo-branco de acordo com os métodos imersão em ácido oxálico e straw test, respectivamente. Esses genótipos podem ser indicados como fontes de resistência para programas de melhoramento. Ambos os métodos analisados são complementares entre si; no entanto, o straw test é mais eficiente na avaliação da resistência dos genótipos de algodão ao mofo-branco.

Abstract: The objective of this work was to evaluate the efficiency of the straw and oxalic acid tests to identify resistance levels of white and colored cotton (Gossypium hirsutum) genotypes to white mold (Sclerotinia sclerotiorum). Ten genotypes were evaluated: five with colored fiber, four with white fiber, and a white-fiber susceptible genotype. The genotypes MAB-1 with white fiber and MAC-2 with colored fiber were the most resistant to white mold, according to the immersion in oxalic acid and straw tests, respectively. These genotypes can be recommended as resistance sources for breeding programs. Both assessed tests are complementary to each other; however, the straw test is more efficient in evaluating the resistance of cotton genotypes to white mold.

RESUMO Objetivo: Analisar os afastamentos laborais de trabalhadores por transtornos mentais e comportamentais. Método: Estudo transversal, censitário, realizado por meio dos dados do banco de dados do Instituto Nacional do Seguro Social, com todos os registros de trabalhadores, nos meses de junho e julho de 2017. Os dados foram analisados com o uso da estatística descritiva e testes inferenciais. Resultados: A amostra foi de 2.449 trabalhadores. Os trabalhadores que se afastaram por transtornos mentais e comportamentais eram, majoritariamente, mulheres, com idade entre 31 e 40 anos e renda inferior ou igual a um ou dois salários mínimos. Os transtornos de humor foram a principal causa do primeiro e segundo afastamento. O ramo de atividade urbana foi considerado um fator de risco para mais de um afastamento (p<0,05). Os seguintes transtornos foram fortemente associados a mais de um afastamento no trabalho (p<0,001): transtorno de humor; esquizofrenia; transtornos esquizotípicos e delirantes; transtornos relacionados ao uso de substâncias psicoativas; transtornos relacionados ao estresse; e transtornos somatoformes. Conclusão: Espera-se estimular os empregadores a investirem nos aspectos relacionados à saúde mental dos seus trabalhadores, com vistas a promover a saúde e evitar o afastamento laboral.

ABSTRACT Objective: To analyze workers’ cases of work leave caused by mental and behavioral disorders. Method: A cross-sectional census study conducted between June and July 2017 in which data were used from the National Social Security Institute database, with all workers’ records. Data were analyzed by using descriptive statistics and inferential tests. Results: The sample included 2,449 workers. Workers who were on leave because of mental and behavioral disorders were mostly women, aged between 31 and 40 years and with an income of less than or equal to one or two minimum wages. The first and second reasons for work leave were mood disorders. Working in an urban setting was considered a risk factor for more than one work leave (p<0.05). The following disorders were strongly associated with more than one work leave (p<0.001): mood disorder; schizophrenia; schizotypal and delusional disorders; disorders related to the use of psychoactive substances; stress-related disorders; and somatoform disorders. Conclusion: Employers are encouraged to invest in the mental health of their workers with a view to promoting health and avoiding work leave.

Los trastornos de humor fueron la principal causa de la primera y segunda baja. La rama de actividad urbana estuvo considerada como un factor de riesgo para más de una baja (p<0,05). Los siguientes trastornos estuvieron fuertemente asociados con más de una baja laboral (p<0,001): trastorno de humor; esquizofrenia; trastornos esquizotípicos y delirantes; trastornos relacionados con el uso de sustancias psicoactivas; trastornos relacionados con el estrés; y trastornos somatoformes. Conclusión: Se espera estimular a los empleadores a que inviertan en los aspectos relacionados con la salud mental de sus trabajadores, con vistas a promover la salud y evitar la baja laboral.
