Aim To analyze associations between sociodemographic factors, self-perception, self-care practices in health with Oral Health Literacy (OHL) levels among users of Primary Health Care (PHC). Methods A cross-sectional and analytical study was performed in Piracicaba (São Paulo), Brazil, in 2018, with a convenience sample of users of PHC that were aged over 18 years. Data were collected with a questionnaire by a trained dentist in two Family Health Units. The outcome variable was OHL, measured by the OHLA-B instrument, which was dichotomized by median into low (≤8 point) and high (>8 point). The independent variables were sociodemographic conditions (age, sex, self-declared skin color, and education), self-perceived oral health and self-care practices in health (tooth brushing frequency, smoking habits, reason for the last visit to the dentist, and source of health information search). Unadjusted and adjusted analyses were performed between OHL and independent variables for multiple logistic regression model (p≤0.05). Results The sample consisted of 450 adults. A total of 54.7% had a low OHL. After adjusting for sex and age, OHL was associated with skin color (OR=0.57; 95%CI=0.37-085), educational level (OR=4.92; 95%CI=3.16-7.79), health information from health professionals (OR=2.40; 95%CI=1.42-4.16) and internet (OR=2.88; 95%CI=1.59-5.32), toothbrushing >1 time a day (OR=3.23; 95%CI=1.27-9.92) and smokers (OR=0.42; 95%CI=0.23-0.73). After adjusting for sex, age and income, OHL was associated with (OR=0.63; 95%CI=0.41-096), educational level (OR=4.06; 95%CI=2.57-6.51) and smokers (OR=0.48; 95%CI=0.26-0.84). Conclusions Low OHL was associated with socioeconomic factors, source of information and smoking. This fact highlights the importance of health professionals to promote OHL.

Abstract BACKGROUND: The Hip Sports Activity Scale (HSAS) is a reliable and valid tool for determining the levels of sports activities among patients with femoroacetabular impingement (FAI). OBJECTIVE: To translate and cross-culturally adapt the HSAS to the Brazilian Portuguese language. DESIGN AND SETTING: This was a cross-sectional study conducted at the State University of Rio de Janeiro. METHODS: The Brazilian version of the HSAS was developed following a process that comprised six steps: translation, synthesis, back-translation, review by committee, pretesting and submission of documentation to the developers. The translation phase involved three independent bilingual translators whose mother language was Brazilian Portuguese. The back-translation phase involved three independent translators whose mother language was English. In order to verify comprehension of the questionnaire, 30 undergraduate students in physical education (65% men), with mean age 23.2 years (standard deviation = 6.8), participated in the pre-testing phase. RESULTS: During the translation step, some terms and expressions were changed to obtain cultural equivalence to the original HSAS. In the pre-testing phase, each item of the scale showed a comprehension level of 100%. CONCLUSION: The HSAS was translated from English to the Brazilian Portuguese language and adapted to Brazilian culture. The HSAS validation is ongoing.

Abstract The article portrays an investigation whose objective was to analyze the implications of the pedagogical work developed in a curricular component entitled: 'Pedagogy of Struggles', in the second half of 2020, prepared in remote conformation, in a federal higher education institution, in the state of Minas Gerais/BR. It was a qualitative investigation. The sample group had twenty-eight apprentices, being fourteen men and the same number of women. In terms of analytical procedures, the empirical materials produced during the classes were scrutinized. To examine them, content analysis was used as a technique. The results showed success in relation to the theoretical contributions selected to the discipline, with emphasis on contents with social relevance and those that provided epistemological basis for the development of the teaching of Fighting, in the different stages of basic education. Another highlight referred to the way the meetings were conducted, especially when there were “practical” activities. In terms of limits, the emphasis fell on the “lack of body contact”, constituting the great challenge for the teaching of Fighting/Martial Arts at school, due to its remote configuration.

Resumo O artigo retrata uma investigação cujo objetivo consistiu em perscrutar as implicações do trabalho pedagógico desenvolvido num componente curricular intitulado: ‘Pedagogia das Lutas’, no segundo semestre de 2020, elaborado em conformação remota, em uma instituição de ensino superior federal, no estado de Minas Gerais/BR. Tratou-se de uma pesquisa de natureza qualitativa. O grupo amostral contou com vinte e oito aprendizes, sendo quatorze homens e o mesmo número de mulheres. Em termos de procedimentos analíticos foram escrutinados os materiais empíricos produzidos por ocasião das aulas. Para examiná-los empregou-se a análise de conteúdo, enquanto técnica. Os resultados expuseram êxito em relação aos aportes teóricos selecionados à disciplina, com realce para os conteúdos correlatos e àqueles que forneceram subsídio epistemológico para o desenvolvimento do ensino de Lutas nas diferentes etapas da educação básica. Outro destaque referiu-se ao modo de condução dos encontros, em especial, quando houve atividades “práticas”. Em termos de limites a ênfase recaiu na “falta de contato corporal”, configurando-se como o grande desafio para o ensino de Lutas/Artes Marciais na escola, em razão da conformação remota.

Abstract This study aimed to investigate the association between Oral Health Literacy (OHL) and dental outcomes. A sample of 920 adults above 18 years of age living in areas covered by 10 Family Health Units (FHUs) in a large city in São Paulo state, Brazil, was included. OHL was assessed using the short-form Health Literacy in Dentistry Scale (HeLD-14). Data on sociodemographic factors, oral health, and general health were obtained through a structured questionnaire. The investigated outcomes “tooth loss” and “reason for the last dental appointment” were evaluated using self-reported data. Simple logistic regression models were used to analyze the associations between each independent factor and outcomes. Factors that presented a significance level of ≤0.20 in the bivariate analysis were included in the hierarchical multiple logistic regression models. Participants with an education level up to high school, low OHL, and poor/fair self-rated oral health had 1.35 (95%CI, 1.01-1.80), 1.48 (95%CI, 1.12-1.95), and 1.46 (95%CI, 1.11-1.92) times more probability to report missing teeth, respectively. Adults from families with lower monthly income, low OHL, and poor/fair self-rated oral health had 1.70 (95%CI, 1.29-2.26), 1.89 (95%CI, 1.42-2.51), and 1.73 (95%CI, 1.30-2.30) times more chance, respectively, to have gone to the last dental appointment due to pain or caries. Adults with low OHL levels are more likely to have missing teeth and have gone to the last dental visit for pain, reinforcing the importance of OHL as an important determinant for promoting oral health.

Abstract Food insecurity is a complex phenomenon that affects the health and wellbeing of vulnerable families. The aim of this study was to investigate the relationship between household food insecurity, dental caries, oral health-related quality of life, and social determinants of health among Indigenous adults. A cross-sectional study was conducted among Kaingang adults aged 35-44 years old from the Guarita Indigenous Land, Brazil. Food insecurity was assessed through the EBIA scale. Dental caries was assessed using the DMFT index. Participants answered the OHIP-14 questionnaire and a structured interview. Descriptive and multivariate analyzes using Poisson regression models were performed. The final sample included 107 adults from 97 households. Approximately 95% lived in food insecure families. Severe food insecurity was present in 58% of the households. The phenomenon was associated to the Bolsa Família benefit, household size, and greater perception of oral health impacts on quality of life. The high number of families affected by food insecurity reveals the social vulnerability of the Kaingang people. Food insecurity in Kaingangs adults is associated to oral health perception and social determinants of health.

ABSTRACT The objective with the work was to evaluate, during storage, the rice seeds physical and physiological quality, cultivar IRGA 424 RI, dried with different drying air temperatures. For such, rice seeds were harvested with a moisture content of 22%. Then, they were subjected to drying in a cross-flow dryer, operating in an intermittent system and using the 55 and 65 ºC drying air temperatures. After, samples containing 50 kg of seeds were stored in PP Woven Bags for 240 days. After drying and every 60 days, physical and physiological analyses were performed. The experiment was conducted under a completely randomized design, arranged in a split-plot scheme, with 4 replications. The physical quality, estimated by the seed hectoliter weight, decreased during storage, regardless of the drying air temperature. The germination percentage, as well as the vigor increased during storage, regardless of drying air temperature due to the dormancy overcoming process. The dry seeds with the highest drying air temperature showed less vigor throughout the storage, according to the cold test. The rice seeds drying with an air temperature of 65 ºC, promoted a higher drying speed and did not negatively influence the seeds physical and physiological quality, however, reduced the vigor.

RESUMO Objetivos: descrever a utilização dos testes imunocromatográficos e das sorologias laboratoriais na avaliação de imunodiagnósticos durante o pré-natal. Métodos: estudo de abordagem quantitativa, caracterizado como uma pesquisa observacional do tipo descritiva. Foram coletados dados dos prontuários de 46 gestantes que realizam acompanhamento pré-natal na Atenção Primária à Saúde de uma capital do Sul do Brasil. Os dados obtidos tiveram seu conteúdo codificado e analisados mediante estatística descritiva. Resultados: foi identificada uma média de 43,1 dias desde a solicitação das sorologias laboratoriais até a avalição profissional. Nesse sentido, também foi verificado que 21,7% das gestantes não coletaram as sorologias solicitadas durante a primeira consulta pré-natal e que foram aplicados testes imunocromatográficos em apenas 10,8% dos participantes. Conclusões: apesar dos estudos para o aprimoramento da consulta pré-natal, do fornecimento de novas tecnologias e da educação permanente ofertada aos profissionais, ainda persistem questões que dificultam a concreta implementação dos testes imunocromatográficos.

ABSTRACT Objectives: to describe the use of affinity chromatographies and laboratory serologies in the evaluation of immunodiagnoses during prenatal. Methods: quantitative study, characterized as a descriptive observational research. Data was collected from the records of 46 pregnant women who were in prenatal follow up in the Primary Health Care in a capital in the South of Brazil. The data found was codified and analyzed using descriptive statistics. Results: a mean of 43.1 days was found to take place between the request of laboratory serology and the evaluation by a professional. It was also found that 21.7% of pregnant women did not collect the serologies requested during the first prenatal consultation, and that the affinity chromatographies were only applied in 10.8% of the participants. Conclusions: in spite of the studies for the improvement of prenatal consultations, for the provision of new technologies and for the permanent education offered to the professionals, there are still questions that make the actual implementation of affinity chromatographies more difficult.

RESUMO O objetivo desse estudo é avaliar o ajuste das Redes Neurais Artificiais (RNA) para estimativa de altura e avaliação dos efeitos do consórcio em um plantio misto de Eucalyptus globulus (E) e Acacia mearnsii (A). O experimento foi instalado em 2005, em duas fazendas no município de Piratini - RS, onde foram plantadas as espécies Eucalyptus globulus (E) e Acacia mearnsii (A), em monocultura e plantio misto em linha simples (50%E:50%A - LS) e linhas duplas (50%E:50%A - LD). O treinamento e a avaliação das redes neurais foram realizados no software R-project com o pacote neuralnet. Todas as RNAs, desde as mais simples até as mais complexas apresentaram altos valores para Rŷy e baixos para Syx, VIÉS e RQEM, com resultados superiores nas RNA 3, 4 e 6, o que demostrou que as informações DAPmin, DAPmed e DAPmax são importantes atributos do povoamento. Além disso, as RNAs foram capazes de captar os diferentes padrões de crescimento demonstrados pelas espécies as diferentes formas de consórcio, sendo indicadas para a estimativa de altura em monoculturas e plantios mistos de Eucalyptus globulus e Acacia mearnsii, e apenas uma RNA pode ser necessária para representar toda a população.

ABSTRACT The objective of this study is to evaluate the fit of Artificial Neural Networks (ANN) for height estimation and evaluation of the effects of consortium in a mixed-species plantation of Eucalyptus globulus (E) and Acacia mearnsii (A). The experiment was installed in 2005, on two farms in the municipality of Piratini - RS, where was planted the species Eucalyptus globulus (E) and Acacia mearnsii (A), in monoculture and mixed in simple lines (50%E:50%A - SL), and double lines (50%E:50%A - DL). The training and evaluation of the networks were made in R-project with the package neuralnet. All ANNs, from the simplest to the most complex, showed high values for Rŷy and low for Syx, BIAS and RMSE, with superior results in ANN 3, 4, and 6, which demonstrates that the information of DBHmin, DBHmean, and DBHmax were important stand attributes. Furthermore, the ANNs were able to capture the different growth patterns shown by the species in the different forms of consortiums, therefore is indicated for the height estimation in monocultures and mixed plantations of Eucalyptus globulus and Acacia mearnsii, and only one ANN would be necessary to represent the entire population.

Resumo: Para proporcionar maior seletividade do herbicida clomazone à cultura do arroz, pode-se utilizar o protetor dietholate em conjunto com outros tratamentos de sementes (ST), o que possibilita o uso de doses maiores do herbicida. O objetivo do trabalho foi avaliar a interação entre o tratamento de sementes que utilizam fungicidas e inseticidas e o protetor dietholate em arroz irrigado. Foram realizados três experimentos, sendo que o primeiro foi conduzido em laboratório, em delineamento experimental inteiramente casualizado com quatro repetições. Neste caso, testou-se diferentes ST e intervalo em dias entre o tratamento de sementes e a semeadura. O segundo e o terceiro experimentos foram realizados em campo, seguindo um delineamento experimental de blocos casualizados com quatro repetições. No experimento dois, foram testados diferentes fungicidas nos ST com ou sem a adição de dietholate; enquanto no experimento três avaliou-se o efeito dos ST com fungicidas e dietholate, quando aplicados juntamente com clomazone. Os resultados evidenciaram que a associação carboxin + thiram + dietholate reduziu a germinação, o vigor de sementes e a matéria seca da parte aérea de plantas de arroz irrigado. O aumento no tempo entre o ST e a semeadura reduziu a germinação de arroz. A associação de fungicidas em combinação com dietholate no ST pode ter ação antagônica e interferir no estabelecimento da cultura.

Abstract: The plant safener dietholate can be used for seed treatments (ST) to improve the selectivity of clomazone in rice cultures, thus allowing the application of higher dosages of this herbicide. The objective of this research was to evaluate the interaction between seed fungicide-insecticide treatments with and the plant safener dietholate in irrigated rice. Three experiments were carried out, and the first of them was conducted in a laboratory, following a completely randomized experimental design with four replications. Different ST and treatment-to-sowing intervals were evaluated. The second and third experiments were performed in field conditions, in a completely randomized block design with four replications. In experiment two, seeds were treated with different fungicides, in association or not with dietholate; while in experiment three, the effect of the ST with fungicides and dietholate with clomazone application were assessed. The results evidenced that the association between carboxin + thiram + dietholate reduced seed germination, vigor, and the dry mass of shoot of rice plants. The longer it takes between ST and sowing, the more rice seed germination is negatively affected. The association between fungicides and dietholate may have been antagonistic, and thus interfered with the culture growth potential.
