ABSTRACT OBJECTIVE To evaluate the evolution of the dietary patterns of adolescents in the northeast region of Brazil. METHODS Secondary analysis of data from the Pesquisa de Orçamentos Familiares (POF – Household Budget Surveys), collected by the Brazilian Institute of Geography and Statistics (IBGE) in the years 2008–2009 and 2017–2018. A total of 3,095 adolescents were evaluated in 2008–2009 and 3,015 in 2017–2018. Food consumption was assessed using two dietary records in 2008–2009 and two 24-hour recalls in 2017–2018, applied on non-consecutive days. Based on these data, principal components factor analysis (PCFA) was performed, followed by orthogonal rotation of the varimax type, to derive dietary patterns, stratified by sex. The results were described as means or percentage frequencies, with their respective 95% confidence intervals. RESULTS Three main dietary patterns were identified among adolescents from the northeast region of Brazil. Among boys, in 2008–2009, the patterns were called snacks, traditional Brazilian, and coffee; and in 2017–2018, traditional Brazilian, snacks, and mixed, in this order of representativeness of the group’s eating habits. Among female adolescents, in 2008–2009, the patterns were snacks, traditional Brazilian, and coffee; and in 2017–2018, traditional Brazilian, snacks, and processed meats. CONCLUSION The dietary patterns identified in 2008–2009 and 2017–2018 were similar in both genders; however, the snacks pattern, which explained most of the data variability in 2008–2009, was replaced by the traditional Brazilian.

Resumen En la enseñanza de la Química, en el Nivel Medio Superior, se ha encontrado que, durante el proceso de enseñanza y aprendizaje de la nomenclatura química inorgánica, los estudiantes tienden a memorizar los contenidos y no adquieren aprendizajes significativos. En este trabajo se hace una propuesta de aprendizaje basado en juegos acerca de la nomenclatura química de sales binarias. El material lúdico desarrollado consistió en utilizar como base el cubo Rubik, en su versión estándar, al que se le colocaron pegatinas con la representación simbólica de diversas sales binarias, así como los nombres en nomenclatura tradicional, Stock y IUPAC. Esta herramienta didáctica se denominó cubo RUBIQUIM. La herramienta se utilizó en tres grupos del nivel medio superior, en donde los estudiantes resolvieron el cubo RUBIQUIM. Para determinar el impacto del material lúdico, se aplicó un cuestionario con preguntas de N1 a N3, de acuerdo con la taxonomía de Bloom, y se determinó el índice de Hake. Los grupos en los que se aplicó el aprendizaje basado en juegos mostraron un mejor rendimiento académico y un mayor aprendizaje cognitivo que el grupo control. El índice de Hake de 0.56, en las preguntas de N2 y N3, indica la eficacia del aprendizaje interactivo.

Abstract In the teaching of Chemistry, in the Upper Middle Level, it has been found that, during the process of teaching and learning the inorganic chemical nomenclature, students tend to memorize the contents and do not acquire significant learning. In this paper, a proposal for game -based learning about the chemical nomenclature of binary salts is made. The playful material developed consisted of using as a base the Rubik’s cube, in its standard version, to which stickers were placed with the symbolic representation of various binary salts, as well as the names in traditional nomenclature, Stock and IUPAC. This didactic tool was called the RUBIQUIM cube. The tool was used in three groups of the upper secondary level, where the students solved the RUBIQUIM cube. To determine the impact of the playful material, a questionnaire was applied with questions from N1 to N3, according to Bloom’s taxonomy, and the Hake index was determined. The groups in which game-based learning was applied showed better academic performance and greater cognitive learning than the control group. The Hake index of 0.56, in the N2 and N3 questions, indicates the effectiveness of interactive learning.

Abstract We evaluate how the concentrations of inorganic nutrients and chlorophyll a vary in a heterogeneous area (Equatorial SW Atlantic), covering a gradient from stations closer to the coast to others more distant associated or not with turbid-zone reefs. Vertical temperature (27.9 ± 0.10 °C; mean ± standard deviation) and salinity (36.2 ± 0.14) profles showed that the water column is well mixed (0-30 m depth). The oligotrophic condition was marked by low concentrations of phosphate (0.30 ± 0.22 µM) and dissolved inorganic nitrogen (0.64 ± 0.74 µM). Moreover, dissolved reactive silicon (DSi) was low in most samples (< 2.0 µM), but higher (>10 µM) in nearshore stations, probably related to continental runoff and/or resuspension of the bottom sediments. The pelagic phytoplankton biomass indicated that chlorophyll a (0.25 ± 0.08 µg L-1) was low, positively correlated with light and negatively correlated with nutrients, indicating possible phytoplankton uptake. Chlorophyll a concentrations were lower in stations closer to the coast and higher in some stations near the reefs, indicating that the latter could be more prone to phytoplankton development and depletion of nutrients, especially DSi. Therefore, although oligotrophy is present along this coast, we found some unexpected heterogeneity of nutrient and chlorophyll a distributions, which were probably infuenced by benthic-pelagic coupling due to the presence of extensive reefs, sponge gardens (18-30 m depth), and the proximity to the coast. These results highlight the importance of understanding the heterogeneity of ocean productivity, especially in lesser known low-latitude areas, which showed distinct nutrient and chlorophyll a levels related to the occurrence of tropical reefs that are capable of supporting important fsh stocks and unique biological communities.

Abstract Introduction Post-COVID-19 syndrome is characterized by chronic fatigue and myalgia, among other symptoms, which can limit activities of daily living. Physical therapy protocols with multicomponent exercises combine strength, resistance, balance and gait, producing sig-nificant improvements in functional mobility. Objective Evaluate whether multicomponent rehabilitation is effective in improving functional mobility and quality of life in individuals with post-COVID-19 syndrome. Methods Randomized controlled trial with 59 volunteers, divided into an intervention (IG) and control group (CG), all of whom underwent initial assessment (T0). The IG performed 24 sessions over 12 weeks and the CG did not undergo training. Functional mobility was analyzed using the 6-minute walk test (6MWT) and the Berg balance scale, while the SF-36 questionnaire assessed quality of life. Results In the 6MWT, the IG covered 464.40 + 81.26 meters (T0) and 518.60 + 82.68 meters (T4). The IG Berg scale scores were 48.00 + 4.00 (T0) and 51.90 + 4.26 (T4). In terms of quality of life, the IG obtained mean scores of 96.26 + 10.14 (T0) and 102.60 + 5.53 (T4). None of these measures was statistically significant. Conclusion Individuals who underwent the multicomponent phys-iotherapy protocol showed statistically nonsignificant increases in the variables studied.

ABSTRACT The rational exploitation of the land requires planning its agricultural use, which can be supported by the agricultural land suitability (ALS) assessment. The scheme to assess ALS proposed by Food Agricultural Organization (FAO) has been adopted in Brazil based on guiding charts for subtropical, humid tropical and semi-arid tropical climate. However, the guiding chart used for the semi-arid region has dramatically limited the ALS in drylands on which rainfed agriculture has been practiced. In this study, an adequation for the ALS assessment regarding the edaphoclimatic conditions of semi-arid region was proposed to improve the representation of agricultural areas and to allow a better planning of soil conservation practices. The ALS of the south region of Ceará State (Brazil) was assessed according to the FAO scheme and its initial adaptation to the Brazilian conditions; subsequently, this assessment was obtained by two adequations. Adequation I disregarded the limiting factor of water availability, while adequation II, besides disregarding the factor of water availability, established new limits for the classes of effective soil depth. The adequations resulted in an increase of 177.19 % in the areas with regular suitability for crops to the detriment of areas with restricted suitability for crops and areas with suitability only for pasture or grazing lands. The adequations increased the agricultural suitability in 41.26 % of the area of the mapping units, and 16.77 % of them were due to the modifications related to the effective soil depth, while the other 26.35 % were due to the changes related to water availability. The results related to water availability were equivalent to those observed through the dynamic analysis of land-use and cover associated with the rainfall, which demonstrated an increase in the areas for rainfed agriculture and a reduction in fallow and pasture areas in the years with rainfall within the climatic normality. The areas considered suitable for crop production with the adequation of the scheme may be included in soil conservation programs.

Abstract This article aims to analyze whether fund-to-fund transfers have contributed to federal coordination and cooperation of policies aimed at public security in Brazil. To this end, the work was divided into three stages: (i) Survey of National Public Security Fund amounts allocated to the states and the Federal District in the period from 2000 to 2022, before and after the adoption of fund-to-fund transfers; (ii) Conducting semi-structured interviews to raise the perceptions of managers responsible for preparing and coordinating the decentralization process and monitoring the execution of decentralized resources; and (iii) Analysis of the Coordination/Cooperation mechanisms foreseen in the Application Plans prepared by the states in the period. The research findings confirm the results of previous studies on the induction power of fund-to-fund transfers in the cooperation and coordination of national policies for public security. It was verified that the expansion of resources and the obligatoriness of their sharing with the states favored the alignment of state policies with the guidelines established by the Union but that the interaction between bodies, organizations, and members of society on the subject is still incipient.

Resumen El objetivo de este artículo es analizar si las transferencias de fondo a fondo han contribuido a la coordinación y cooperación federal de las políticas dirigidas a la seguridad pública en Brasil. Para ello, el trabajo se dividió en tres etapas: (i) Relevamiento de los montos del Fondo Nacional de Seguridad Pública asignados a los estados y al Distrito Federal en el período 2000-2022, antes y después de la adopción de las transferencias fondo a fondo; (ii) Realización de entrevistas semiestructuradas para conocer la percepción de los gerentes responsables de preparar y coordinar el proceso de descentralización y monitorear la ejecución de los recursos descentralizados; y (iii) Análisis de los mecanismos de coordinación/cooperación previstos en los planes de aplicación elaborados por los estados en el período. Los hallazgos de la investigación confirman los resultados de estudios previos sobre el poder de inducción de las transferencias fondo a fondo en la cooperación y coordinación de políticas nacionales también para el área de seguridad pública. Se verificó que la ampliación de los recursos y la obligatoriedad de compartirlos con los estados favorecieron el alineamiento de las políticas estatales con las directrices establecidas por el Gobierno federal, pero que la interacción entre organismos, organizaciones y miembros de la sociedad sobre el tema es aún incipiente.

Resumo O objetivo deste artigo é analisar a realização de transferências fundo a fundo e avaliar se ela tem contribuído para a coordenação e cooperação federativa de políticas voltadas à segurança pública no Brasil. Para tanto, o trabalho foi dividido em três etapas: (i) levantamento dos valores do Fundo Nacional de Segurança Pública (FNSP), destinados aos estados e ao Distrito Federal, no período de 2000 a 2022, antes e depois da adoção das transferências fundo a fundo; (ii) realização de entrevistas semiestruturadas para levantar as percepções dos gestores responsáveis pela elaboração e coordenação do processo de descentralização e pelo acompanhamento da execução dos recursos descentralizados; e (iii) análise dos mecanismos de coordenação/cooperação previstos nos planos de aplicação elaborados pelos estados no período supracitado. Os achados da pesquisa confirmam resultados de estudos anteriores sobre o poder de indução das transferências fundo a fundo na cooperação e coordenação de políticas nacionais, também para a área de segurança pública. Verificou-se que a ampliação de recursos e a obrigatoriedade de seu compartilhamento com os estados favoreceram o alinhamento das políticas estaduais às diretrizes estabelecidas pela União, mas que ainda é incipiente a interação entre os órgãos, organizações e membros da sociedade em relação ao tema.

Resumo Introdução: Em março de 2020, a Organização Mundial da Saúde declarou o estado de pandemia COVID-19. Foram aplicadas várias medidas, como a reestruturação dos cuidados de saúde primários, que conduziu à acumulação de novas funções pelos profissionais, proporcionando maior stress laboral e maior desgaste com consequente predisposição a síndroma de Burnout. Objetivos: Caracterizar as dificuldades dos profissionais; avaliar a prevalência da síndroma de Burnout; correlacionar a síndroma com variáveis sociodemográficas e profissionais. Métodos: Estudo transversal, observacional e descritivo com componente analítica, aos profissionais dos cuidados de saúde primários de Portugal, que decorreu entre abril e junho de 2021. Foram avaliadas variáveis demográficas e profissionais, assim como a síndroma de Burnout através do Maslach Burnout Inventory - Human Services Survey. Resultados: Foram aceites 1.434 respostas. A maioria dos inquiridos trabalhou durante fins-de-semana ou feriados e horas extraordinárias, assim como foram destacados para outros pólos associados à gestão da pandemia. Um terço não foi renumerado por horas extraordinárias ou incómodas e metade dos profissionais foram vítimas de agressão verbal ou física. A maioria discordou que tivesse suficientes recursos humanos e metade discordou que tivesse suficientes materiais. A prevalência da síndroma de Burnout foi de 20,4%. A síndroma e as suas dimensões associaram-se a idade de serviço, sexo, região, número de inscritos nas unidades funcionais, agressão física ou verbal, trabalho durante os fins-de-semana ou feriados, horas extraordinárias e respetivo não pagamento, assim como destacamento para outros pólos. Conclusões: No presente estudo encontrou-se uma maior prevalência da síndroma de Burnout comparativamente a estudos prévios, possivelmente devido à pandemia COVID-19, corroborada pelas associações encontradas.

Abstract Introduction: In March 2020, the World Health Organization declared the COVID-19 pandemic status. Several measures were applied, such as the restructuring of primary health care, which led to the accumulation of new functions by professionals, originating in more work-related stress and fatigue, with a consequent predisposition to Burnout syndrome. Objectives: Characterize the difficulties of professionals; evaluate the prevalence of Burnout syndrome; correlate the syndrome with sociodemographic and professional variables. Methods: A cross-sectional, observational, and descriptive study with an analytical component of primary health care professionals in Portugal, which took place between April and June 2021. Demographic and professional variables were evaluated, as well as the Burnout syndrome through the Maslach Burnout Inventory - Human Services Survey. Results: 1,434 responses were accepted. Most worked during weekends or holidays and overtime and were allocated to other poles associated with managing the pandemic. A third was not paid for overtime or inconvenient hours and half of the professionals were victims of verbal or physical aggression. Most disagreed that they had enough human resources and half disagreed that they had enough materials. The prevalence of Burnout syndrome was 20.4%. The syndrome and its dimensions were associated with the age of service, sex, region, the number of people enrolled in functional units, physical or verbal aggression, work during weekends or holidays, overtime, and respective non-payment, as well as being allocated to other poles. Conclusions: In the present study, there was a higher prevalence of the syndrome compared to previous studies, possibly due to the COVID-19 pandemic, corroborated by the associations found.

Abstract A bibliographic review was carried out on the effects of sucrose substitute total sugars on the state of oral health. The scientific articles were in the following digital scientific databases: Scopus, PubMed, Web of Science and Ovid. The sources used were freely accessible, 49 of the manuscripts gotten by the search were discarded and 23 were used. 43.5% of the articles included showed results of clinical trials on chewing gums with xylitol, 39.1% about other compounds (stevia, magnolia, erythritol, calcium phosphate), 13% narrative reviews and the 4.4% meta-analysis. Chewing gums made with sucrose substitutes stimulate salivary production, neutralize and raise its pH. That is why, its role in promoting oral health is recognized in several scientific publications. The anticariogenic effects of xylitol were established in various studies. There were not enough studies on the effects of the substances: stevia, d-tagatose, magnolia, erythritol and calcium phosphate.

ABSTRACT Hand-foot-and-mouth disease (HFMD) is a highly contagious viral disease commonly associated to Enteroviruses (EV). During 2018, Brazil faced massive HFMD outbreaks spread across the country. This study aimed to characterize the EV responsible for the HFMD outbreak that occurred in Paraiba State, Brazilian Northeastern region, in 2018, followed by a phylogenetic analysis to detail information on its genetic diversity. A total of 49 serum samples (one from each patient) collected from children ≤ 15 years old, clinically diagnosed with HFMD were tested for EV using conventional RT-PCR and RT-qPCR. EV infection was confirmed in 71.4% (35/49) of samples. The mean and median ages were 1.83 years and one year old, respectively. Twenty-two EV-positive samples were successfully sequenced and classified as EV-A species; 13 samples were also identified with the CV-A6 genotype. The phylogenetic analysis (VP1 region) of three samples revealed that the detected CV-A6 strains belonged to sub-lineage D3. The CV-A6 strains detected here clustered with strains from South America, Europe and West Asia strains that were also involved in HFMD cases during the 2017-2018 seasons, in addition to the previously detected Brazilian CV-A6 strains from 2012 to 2017, suggesting a global co-circulation of a set of different CV-A6 strains introduced in the country at different times. The growing circulation of the emerging CV-A6 associated with HFMD, together with the detection of more severe cases worldwide, suggests the need for a more intense surveillance system of HFMD in Brazil. In addition, this investigation was performed exclusively on serum samples, and the analysis of whole blood samples should be considered and could have shown advantages when employed in the diagnosis of enteroviral HFMD outbreaks.

Resumo O objetivo deste estudo foi avaliar as perdas gestacionais entre 30 e 120 dias de gestação e reconcepção em vacas de corte submetidas à inseminação artificial em tempo fixo (IATF). Foram analisadas 18.462 informações do arquivo zootécnico de animais submetidos a IATF no período da estação de monta de novembro de 2019 a abril de 2020 na região do semiárido de Minas Gerais. Os parâmetros avaliados foram perda gestacional, categoria animal, presença do bezerro ao pé da vaca, escore de condição corporal (ECC) e situação final da estação de monta das fêmeas que perderam gestação após a IATF, os dados foram analisados pelo teste qui-quadrado de Person (χ2) e teste de Kruskal-Wallis, com nível de significância de 5% com uso do programa SPSS. A taxa de prenhez final foi de 58,52%. A taxa de perdas entre o primeiro e segundo diagnóstico gestacional foi de 3,6%. Observou-se dependência entre as variáveis categoria e perda gestacional (X2= 12,374, p<0,05). A presença do bezerro ou não ao pé da vaca, não teve influência em relação a perda gestacional (p>0,05). A diferença do ECC entre as categorias foi significativa (p<0,05). A situação final foi influenciada (p<0,05) pela categoria animal. A ordem de parição e o escore de condição corporal influenciam significativamente a taxa de perda gestacional.

Abstract The objective of this study was to evaluate gestational losses between 30 and 120 days of gestation and reconception in beef cows submitted to fixed-time artificial insemination (FTAI). The 18,462 information from the zootechnical file of animals submitted to FTAI in the period of the breeding season from November 2019 to April 2020 in the semiarid region of Minas Gerais were analyzed. The parameters evaluated were gestational loss, animal category, presence of the calf with the cow, body condition score (BCS) and final situation of the breeding season of the females that lost gestation after FTAI, the data were analyzed by Person's chi-square test (χ²) and Kruskal-Wallis test, with a significance level of 5% with use of the SPSS program. The final pregnancy rate was 58.52%. The loss rate between the first and second gestational diagnosis was 3.6%. Dependence was observed between the variables category and gestational loss (χ²= 12.374, p<0.05). The presence of the calf or not at the foot of the cow had no influence in relation to gestational loss (p>0.05). The difference in BSC between the categories was significant (p<0.05). Final situation was influenced (p<0.05) by animal category. Calving order and body condition score significantly influenced the gestational loss rate.

Abstract Exogenous application of stress inductors can facilitate and accelerate some biological responses that promote plant defense. The objective of the experiment was to quantify some compounds linked to nitrogen metabolism as a function of the application of salicylic acid in Schinus terebinthifolius seedlings submitted to water deficit. The experiment was constituted of four doses of salicylic acid and three periods of water deficit. Quantifications included levels of nitrate, free ammonium, total soluble amino acids, proteins, proline, glycine-betaine and relative water content. When evaluating the relative water content in seedlings of Schinus terebinthifolius at 8 days, it was observed that the dose of 200 mg L-1. Seedlings showed physiological responses when subjected to doses of salicylic acid of 200 and 300 mg L-1. The increase in concentration of proline and glycine are advantageous, because these substances act as osmoregulators and cell protectors against deficit hydrical.

Resumo O objetivo deste trabalho foi avaliar o efeito do retardo de resfriamento de morangos ‘San Andreas’ sobre a manutenção da qualidade dos frutos, bem como sobre os compostos fenólicos totais (CFT) e a atividade antioxidante total (AAT), após o armazenamento refrigerado. Os tratamentos consistiram no resfriamento nos tempos de 0 (controle, resfriamento imediato), 3, 6, 9 e 12 horas (em temperatura ambiente), após a colheita. Após a aplicação dos tratamentos, os frutos foram armazenados sob refrigeração (4 ± 0,5 °C e 92 ± 2% de UR), durante 5, 6, 7 e 8 dias, seguidos por mais 2 dias de exposição, em condição ambiente (20 ± 2 °C e 65 ± 5% de UR). Os morangos com o maior retardo de resfriamento apresentaram maior perda de massa fresca, além de menor firmeza, a partir de 7 dias de armazenamento. De maneira geral, os menores valores de incidência e severidade de podridões foram observados nos frutos do tratamento com resfriamento imediato após a colheita, quando armazenados por 7 e 8 dias, seguidos por mais 2 dias em condições ambiente. O retardo do resfriamento por até 6 horas não causa aumento de podridões até 5 dias de armazenamento refrigerado, mais 2 dias em condições ambiente. Os valores de CFT e AAT apresentaram aumento com o retardo de até 6 horas do resfriamento dos frutos, aos 6 dias de armazenamento seguidos por mais 2 dias em condições ambiente, e a AAT aumentou com o aumento do atraso no resfriamento dos frutos em até 12 horas, após 8 dias de armazenamento mais 2 dias em condições ambiente. O atraso no resfriamento causa perdas na qualidade dos frutos de morango, de acordo com o tempo de armazenamento.

Abstract This work aimed to evaluate the effect of the cooling delay of 'San Andreas' strawberries on the maintenance of fruit quality, as well as on Total Phenolic Compounds (TPC) and Total Antioxidant Activity (TAA) after refrigerated storage. Treatments consisted of no cooling at times 0 (control, immediate cooling), 3, 6, 9 and 12 hours (at room temperature) after harvest. After application of the treatments, the fruits were stored under refrigeration (4 ± 0.5 ºC and 92 ± 2% RH) for 5, 6, 7 and 8 days, followed by a further 2 days of exposure in ambient conditions (20 ± 2 °C and 65 ± 5% RH). Strawberries with the greatest cooling delay added significant loss of fresh mass, in addition to less firmness after 7 days of storage. In general, the lowest values of rot incidence and severity were observed in the fruits of the treatment with immediate cooling after harvest, when stored for 7 and 8 days, followed by 2 more days in ambient conditions. Delaying cooling for up to 6 hours did not cause increased decay for up to 5 days of refrigerated storage, plus 2 days at ambient conditions. The values of TPC and TAA showed a dissipation with a delay of up to 6 hours of cooling of the fruits, at 6 days of storage followed by another 2 days in ambient conditions, and the TAA increased with the increase of the delay in the cooling of the fruits in up to 12 hours, after 8 days of storage plus 2 days at ambient conditions. The delay in cooling could cause losses in strawberry fruit quality, according to storage time.
