Abstract Objective To measure the average time for the diagnosis and for the therapeutic prescription of Continuous Positive Airway Pressure (CPAP) at a hospital in Botucatu Medical School - State University São Paulo, UNESP. Method A retrospective observational study was carried out by collecting data from the electronic medical records of patients over 18-years of age, who had a diagnostic polysomnography testing scheduled between January and December 2017. Result Of the 347 patients eligible for the study, 94 (27.1%) missed follow-up and 103 (29.7%) had a referral for CPAP use. Until February 2021, only 37 (35.9%) of these patients had already acquired and were using the device, the remaining 66 (64.1%) were waiting or gave up the therapy. The mean value of the waiting time interval between the referral of the diagnostic test and its performance was equivalent to 197 days (6.5 months). The mean time between diagnostic polysomnography and CPAP prescription was 440-days (14.5-months), with a total mean time of 624 days (21-months). Conclusion As in other services, the diagnostic-therapeutic flow proved to be highly inefficient, with a long waiting period, difficult access to treatment and a high dropout rate. These findings highlight the need to establish new patient-centered strategies with measures that speed up the flow and facilitate access to CPAP, in order to reduce the morbidity and mortality associated with this condition.

Abstract Self-medication exposes individuals to risks such as adverse reactions, intoxications, drug interactions, therapeutic failures and medication errors. In the COVID-19 pandemic, there was an increase in the purchase and consumption of pharmaceutical products by Brazilians. The present study aimed to estimate the prevalence and factors associated with self-medication in students of a university center in the region of Campo das Vertentes, Southeastern Brazil, as well as to evaluate the incidence during the COVID-19 pandemic. The study had a cross-sectional and quantitative design, with 248 students from a university, in 2021. The findings showed that 67.3% of the participants reported self-medication; 28.7% indicated an increase in self-medication during the pandemic; and 30.9% indicated the beginning in this period. There was a significant difference about: to consider oneself capable of self-medicating, to have the habit of referring drugs to other people and to consume them by indication of others. For those who increased the practice of self-medication in the pandemic, there was an association with the habit of indicating drugs to other people. For those who initiated this practice in the pandemic period, the capacity of self-medication was associated. The results open paths for educational measures on the irrational use of medicines by higher education students, regardless of the education area.

SUMMARY OBJECTIVE: The aim of this study was to evaluate the efficacy of long-term oxygen therapy as a strategy to reduce hospitalization time in patients affected by COVID-19. METHODS: Between April and December 2021, COVID-19 patients with stable clinical conditions needing supplementary oxygen therapy during hospitalization were oriented to have hospital discharge with long-term oxygen therapy and reassessment after 15 days. RESULTS: A total of 62 patients were evaluated and, 15 days after discharge, 69% of patients had suspended long-term oxygen therapy, with no difference between the groups admitted to the intensive care unit or the ward (p=0.319). Among the individuals who needed to maintain long-term oxygen therapy, in addition to worse P/F ratio (265±57 vs. 345±51; p<0.001) and lower partial pressure of oxygen (55±12 vs. 72±11 mmHg; p<0.001), were those more obese (37±8 vs. 30±6 kg/m2; p=0.032), needed more time for invasive mechanical ventilation (46±27 vs. 20±16 days; p=0.029), had greater persistence of symptoms (p<0.001), and shorter time between the onset of symptoms and the need for hospitalization (7 [2–9] vs. 10 [6–12] days; p=0.039). CONCLUSION: Long-term oxygen therapy is an effective strategy for reducing hospitalization time in COVID-19 patients, regardless of gravity. Additionally, more obese patients with persistence of respiratory symptoms, faster disease evolution, and more days of invasive mechanical ventilation needed to maintain the long-term oxygen therapy longer.

ABSTRACT The fertilization management can contribute to a better agronomic performance of rice (Oryza sativa L.) plants in upland conditions. Thus, the objective in this study was to evaluate the development of rice plants fertilized with different doses of nitrogen and phosphorus in upland soil. The experiment was conducted in a greenhouse using pots containing soil collected in the soil top layer of a plinthic alitic Haplic Cambisol. The design was completely randomized with a 4 x 4 factorial scheme, corresponding to 0 (zero), 150, 300 and 450 kg ha-1 of phosphorus and 0 (zero), 100, 200 and 300 kg ha-1 of nitrogen. Plant height, shoot dry matter, grain weight and number of tillers were evaluated. Fertilization with nitrogen and phosphorus positively affects the growth and development of rice plants in Humaitá, Amazonas state, grown in upland soil up to doses between 200 and 300 kg ha-1 of N and around 300 kg ha-1 of P2O5, in a plinthic alitic Haplic Cambisol.

Abstract Background Anabolic androgenic steroid (AAS) abuse has been associated with coronary artery disease (CAD). Pericoronary fat attenuation (pFA) is a marker of coronary inflammation, which is key in the atherosclerotic process. Objective To evaluate pFA and inflammatory profile in AAS users. Methods Twenty strength-trained AAS users (AASU), 20 AAS nonusers (AASNU), and 10 sedentary controls (SC) were evaluated. Coronary inflammation was evaluated by mean pericoronary fat attenuation (mPFA) in the right coronary artery (RCA), left anterior descending coronary artery (LAD), and left circumflex (LCx). Interleukin (IL)-1 (IL-1), IL-6, IL-10, and TNF-alpha were evaluated by optical density (OD) in a spectrophotometer with a 450 nm filter. P<0.05 indicated statistical significance. Results AASU had higher mPFA in the RCA (-65.87 [70.51-60.70] vs. -78.07 [83.66-72.87] vs.-78.46 [85.41-71.99] Hounsfield Units (HU), respectively, p<0.001) and mPFA in the LAD (-71.47 [76.40-66.61] vs. -79.32 [84.37-74.59] vs. -82.52 [88.44-75.81] HU, respectively, p=0.006) compared with AASNU and SC. mPFA in the LCx was not different between AASU, AASNU, and SC (-72.41 [77.17-70.37] vs. -80.13 [86.22-72.23] vs. -78.29 [80.63-72.29] HU, respectively, p=0.163). AASU compared with AASNU and SC, had higher IL-1, (0.975 [0.847-1.250] vs. 0.437 [0.311-0.565] vs. 0.530 [0.402-0.780] OD, respectively, p=0.002), IL-6 (1.195 [0.947-1.405] vs. 0.427 [0.377-0.577] vs. 0.605 [0.332-0.950] OD, p=0.005) and IL-10 (1.145 [0.920-1.292] vs. 0.477 [0.382-0.591] vs. 0.340 [0.316-0.560] OD, p<0.001). TNF-α was not different between the AASU, AASNU, and SC groups (0.520 [0.250-0.610] vs. 0.377 [0.261-0.548] vs. 0.350 [0.182-430]), respectively. Conclusion Compared with ASSNU and controls, AASU have higher mPFA and higher systemic inflammatory cytokines profile suggesting that AAS may induce coronary atherosclerosis through coronary and systemic inflammation.

Resumo Fundamento O uso abusivo de esteroides anabólicos androgênicos (EAA) tem sido associado à doença arterial coronariana (DAC). A atenuação de gordura pericoronária (AGp) é um marcador de inflamação coronária, a qual exerce um papel chave no processo aterosclerótico. Objetivo Avaliar AGp e perfil inflamatório em usuários de EAA. Método Vinte indivíduos que realizavam treinamento de força, usuários de EAA (UEAA), 20 não usuários de EAA (NUEAA), e 10 indivíduos sedentários controle (SC) foram avaliados. Inflamação coronária foi avaliada por atenuação de gordura pericoronária média (AGPm) artéria coronária direita (ACD), artéria descendente anterior esquerda (ADA) e artéria circunflexa (ACX). Interleucina (IL)-1 (IL-1), IL-6, IL-10, e TNF-alfa foram avaliados por densidade ótica (DO) em um espectrofotômetro com um filtro de 450 nm. Um p<0,05 indicou significância estatística. Resultados Os UEAA apresentaram maior AGPm na ACD [-65,87 (70,51-60,70) vs. -78,07 (83,66-72,87) vs.-78,46 (85,41-71,99] unidades Hounsfield (HU), respectivamente, p<0,001) e AGPm na ADA [-71,47 (76,40-66,610 vs. -79,32 (84,37-74,59) vs. -82,52 (88,44-75,81) HU, respectivamente, p=0,006) em comparação aos NUEAA e CS. A AGPm na ACX não foi diferente entre os grupos UEAA, NUEAA e CS [-72,41 (77,17-70,37) vs. -80,13 (86,22-72,23) vs. -78,29 (80,63-72,29) HU, respectivamente, p=0,163). Em comparação aos NUEAA e aos CS, o grupo UEAA apresentaram maiores níveis de IL-1 [0,975 (0,847-1,250) vs. 0,437 (0,311-0,565) vs. 0,530 (0,402-0,780) DO, respectivamente, p=0,002), IL-6 [1,195 (0,947-1,405) vs. 0,427 (0,377-0,577) vs. 0,605 (0,332-0,950) DO, p=0,005) e IL-10 [1,145 (0,920-1,292) vs. 0,477 (0,382-0,591) vs. 0,340 (0,316-0,560) DO, p<0,001]. TNF-α não foi diferente entre os grupos UEAA, NUEAA e CS [0,520 (0,250-0,610) vs. 0,377 (0.261-0,548) vs. 0,350 (0,182-430)]. Conclusão Em comparação aos NUEAA e controles, os UEAA apresentam maior AGPm e maior perfil de citocinas inflamatórias sistêmicas, sugerindo que os EAA podem induzir aterosclerose por inflamação coronária e sistêmica.

ABSTRACT Amazonian soils have been suffering severe changes resulting from human activities in the region, causing significant changes in soil attributes that can contribute to greater susceptibility to erosion processes. Therefore, the present work aimed to estimate the erodibility in natural and anthropic environments in the southern region of the Amazon. Eight areas in the region were selected, including areas of native forest, savannah, cerradão, pasture and reforestation, delimiting 32 sampling points per area, with collections at a depth of 0.00-0.20 m, totaling 256 samples. Next, texture analysis and quantification of soil organic carbon were performed, and then erodibility was estimated by indirect prediction methods, Tukey’s test, Pearson’s correlation and factorial analysis of principal components. According to the results obtained, it was observed that the evaluated areas of native forest 1 and 2, cerradão and pasture present high susceptibility to erosion in relation to the cerrado, reforestation with genipap, teak and mixed areas. Therefore, it was noted that the high level of erodibility is associated with a greater predominance of sand fraction, K factor, Ki Kr and low clay content, as well as with the management employed in the areas. processes Therefore Amazon selected savannah 3 area 0.000.20 000020 0.00 0.20 0 00 20 0.00-0.2 m 25 samples Next performed methods Tukeys Tukey s test Pearsons Pearson components obtained 2 cerrado genipap fraction factor content 000 0.000.2 00002 0.0 020 0.2 0.00-0. 0.000. 0000 0. 02 0.00-0 0.000 0.00-

Abstract Introduction: patients with COVID-19 undergo changes in leukocyte count, respiratory disorders, and an increase in inflammatory substances. To improve the inflammatory condition, some nutrients can be used, including arginine, omega-3 fatty acids and nucleotides. This study aims to evaluate how oral immunonutrient supplements affects serum C-reactive protein (CRP) levels and lymphocyte count in patients with COVID-19. Methods: in this double-blind clinical trial, we randomized 43 adult patients with COVID-19 to receive a standard high-protein normocaloric supplement (control) or an immunonutrient-enriched supplement (experiment) for 7 days. The primary outcome was to evaluate changes in total lymphocyte count and serum level of CRP. The assessment of risk and nutritional status of these patients was also performed. Results: forty-three patients with mean age of 41.5 (± 1.8) years were followed up, 39.5 % of them women. The mean body mass index was 27.6 (± 0.8) kg/m² and 58.1 % had low nutritional risk. In the experiment group, there was a CRP reduction of 23.6 (± 7.5) mg/L, while in the control branch the decrease was 14.8 (± 12.1) mg/L (p = 0.002). There was an increase in lymphocytes in the experiment group (+367.5 ± 401.8 cells/mm³) and a reduction in the control group (-282.8 ± 327.8 cells/mm³), although there was no statistical significance (p = 0.369). Relative risk (RR) of treatment in reducing CRP by 30 % or more was 4.45 (p < 0.001; 95 % CI, 1.79-11.07). RR in increasing lymphocyte count by 30 % or more was 1.28 (p = 0.327; 95 % CI, 0.67-2.45). Conclusion: we conclude that immunonutrient supplements seem to reduce CRP levels more than standard high-protein normocaloric supplements.

Resumen Introducción: los pacientes con COVID-19 sufren cambios en el recuento de leucocitos, trastornos respiratorios y aumento de sustancias inflamatorias. Para mejorar la condición inflamatoria se pueden usar algunos nutrientes, como la arginina, los ácidos grasos omega-3 y los nucleótidos. Este estudio tiene como objetivo evaluar cómo los suplementos de inmunonutrientes orales afectan a los niveles séricos de proteína C-reactiva (PCR) y al recuento de linfocitos en pacientes con COVID-19. Métodos: en este ensayo clínico doble ciego, aleatorizamos a 43 pacientes adultos con COVID-19 para recibir un suplemento normocalórico estándar alto en proteínas (control) o un suplemento enriquecido con inmunonutrientes (experimento) durante 7 días. El resultado primario fue evaluar los cambios en el recuento total de linfocitos y el nivel sérico de PCR. También se realizó la evaluación del riesgo y el estado nutricional de estos pacientes. Resultados: cuarenta y tres pacientes con edad media de 41,5 (± 1,8) años fueron seguidos, el 39,5 % de ellos mujeres. El índice de masa corporal medio fue de 27,6 (± 0,8) kg/m² y el 58,1 % tenían bajo riesgo nutricional. En el grupo experimental hubo una reducción de la PCR de 23,6 (± 7,5) mg/L, mientras que en la rama de control la disminución fue de 14,8 (± 12,1) mg/L (p = 0,002). Hubo un aumento de linfocitos en el grupo experimental (+367,5 ± 401,8 células/mm³) y una reducción en el grupo de control (-282,8 ± 327,8 células/mm³), aunque no hubo significación estadística (p = 0,369). El riesgo relativo (RR) del tratamiento para reducir la PCR en un 30 % o más fue de 4,45 (p < 0,001; IC 95 %: 1,79-11,07). El RR en el aumento del recuento de linfocitos en un 30 % o más fue de 1,28 (p = 0,327; IC 95 %: 0,67-2,45). Conclusión: se concluye que los suplementos de inmunonutrientes parecen reducir los niveles de PCR más que los suplementos normocalóricos estándar altos en proteína.

RESUMO O comportamento da alvenaria estrutural resulta do desempenho de cada componente: unidades, juntas de argamassa, grautes e armaduras. Comercialmente, os blocos para alvenaria são produzidos com concreto seco ou zero-slump. Sua dosagem e propriedades físicas se diferem consideravelmente dos concretos convencionais e dependem da eficiência de compactação das máquinas vibroprensas. Ensaiar elementos de alvenaria em tamanho natural é dispendioso e requer uma infraestrutura específica. Nessa perspectiva, modelagens computacionais baseadas em formulações numéricas como o Método dos Elementos Finitos (FEM) podem se tornar alternativas viáveis e de grande potencial. Este trabalho objetiva analisar numérica e experimentalmente a influência do tipo de agregado nas propriedades físicas e, sobretudo, mecânicas (módulo secante e resistência à compressão) de blocos vazados de concreto para alvenaria estrutural. Foram testadas três resistências de bloco (6, 12 e 24 MPa), contendo três tipos de agregado (basalto, gnaisse e calcário). Dos resultados, observou-se que em blocos menos resistentes a porosidade das misturas influenciou mais as propriedades mecânicas que a rigidez do agregado. À medida que os concretos se tornam mais densos e resistentes, esse comportamento muda. Os modelos implementados e calibrados pelos resultados experimentais reproduziram satisfatoriamente o modo de ruptura dos blocos, os resultados de módulo e de resistência.

ABSTRACT The structural masonry behavior results from the performance of each component: units, mortar joints, grouts, and reinforcement. Commercially, masonry blocks are made with called dry or zero-slump concrete. Its dosage and physical properties differ considerably from conventional concretes and depend on vibropress machines compaction efficiency. Testing full-size masonry elements is expensive and demand a specific infrastructure. Thus, computer modeling based on numerical formulations such as the Finite Element Method (FEM) can become viable and high potential alternatives. This work aims to analyze numerically and experimentally the influence of aggregate type on physical and, mainly, mechanical properties (ultimate strength and secant deformation module in compression) of hollow concrete blocks for structural masonry. Units of three different strengths (6, 12 and 24 MPa) and containing three different aggregate types (basalt, gneiss, and limestone) were tested. From results, it was observed that in less resistant blocks, the mixtures porosity influenced mechanical properties more than aggregate stiffness. As concretes become denser and stronger, this behavior changes. The models implemented and calibrated by the experimental results were satisfactory in reproducing the failure mode of the blocks, secant modulus and compressive strength results.

Resumo Trichinella spp. é um parasito zoonótico de distribuição mundial detectado em carnívoros e onívoros de sangue quente e humanos. Até o momento, o Brasil é considerado pela Organização Mundial de Saúde Animal livre do ciclo doméstico da doença, enquanto o ciclo silvestre do parasito tem status de infecção em áreas limitadas. No entanto, em países vizinhos como a Argentina, larvas do parasito foram encontradas na fauna silvestre. O presente estudo teve como objetivo determinar a ocorrência de Trichinella spp. em animais silvestres atropelados no Paraná, Brasil. Amostras biológicas de 71 animais silvestres – 29 Didelphis albiventris, 11 Nasua-nasua, dez Cerdocyon thous, sete Dasypus novemcinctus, seis Leopardus gattulus, seis Sphiggurus spinosus e dois Puma concolor– coletadas de novembro de 2016 a novembro de 2021 foram submetidas à digestão artificial, seguindo a metodologia descrita do REGULAMENTO (CE) Nº2075/2005. Não foram encontradas larvas de Trichinella spp. nas carcaças dos animais selvagens atropelados. No entanto, considerando o amplo espectro de possíveis reservatórios que podem atuar como elo entre os ciclos silvestre e doméstico e considerando a condição atual da triquinelose silvestre no Brasil em áreas limitadas, o monitoramento frequente da fauna silvestre é necessário.

Abstract Trichinella spp. are zoonotic parasites that are widely distributed in warm-blooded carnivores and omnivores, including humans. Until the present moment, Brazil has been considered by World Animal Health Organization free from the domestic cycle of trichinellosis, whereas the parasite’s sylvatic cycle has the status of infection in limited zones. However, neighboring countries such as Argentina have reports of parasite larvae in the wild fauna. The present study aimed to determine the occurrence of Trichinella spp. in road-killed wild animals in Paraná, Brazil. Biological samples from 71 wild animals—29 Didelphis albiventris, 11 Nasua nasua, ten Cerdocyon thous, seven Dasypus novemcinctus, six Leopardus guttulus, six Sphiggurus spinosus and two Puma concolor—collected from November 2016 to November 2021 were subjected to artificial digestion, following the methodology described in the REGULATION (EC) No. 2075/2005. No Trichinella spp. larvae were detected in the carcasses of the road-killed wild animals. However, considering the wide spectrum of possible reservoirs that could act as a link between the sylvatic and domestic cycles and considering the current Brazilian status of sylvatic trichinellosis in limited zones, frequent monitoring of wild fauna remains necessary.

RESUMO O objetivo deste trabalho é, a partir dos preceitos da decolonialidade (QUIJANO, 2005; WALSH, 2009), analisar as listas de leituras obrigatórias de vestibulares, investigando: os efeitos retroativos dessas listas nas práticas de letramentos literários escolares; a diversidade social, étnica, sexual e de gênero que elas promovem; como movimentam o cânone literário escolar; e como contribuem (ou podem contribuir) para uma maior democratização da/na educação literária. Para isso, selecionamos listas dos últimos vestibulares de sete universidades públicas, buscando contemplar instituições de cada região do Brasil. Tomamos as listas de leituras como importante ferramenta de legitimação de autores e obras literárias para o contexto escolar. A análise proposta é qualitativo-interpretativista (MOITA-LOPES, 1994; 2006) e compreende que todas as práticas de letramentos literários são ideológicas (STREET, 2014), o que pressupõe tanto uma investigação em diálogo com os contextos sociais e com os diversos atores/agentes em torno das práticas de letramentos analisadas, quanto uma interpretação que não isole os dados da pesquisa das relações de poder e disputas discursivas exercidas em torno deles. A partir da constatação de que a inclusão promovida por essas listas de obras literárias se limita apenas a determinadas diversidades, procuramos analisar, especialmente, a ausência de autores e obras LGBTQIA+, a fim de compreender as razões dessa ausência e demonstrar o potencial educativo que obras e autores desses grupos sociais poderiam ter na construção de práticas de letramentos literários escolares de reexistência (SOUZA, 2011; WALSH, 2009) para uma educação transgressora (HOOKS, 2017) e democrática.

ABSTRACT This paper, based on the precepts of decoloniality (QUIJANO, 2005; WALSH, 2009), aims to analyze the required readings lists for college entrance examinations (vestibular) by investigating: the retroactive effects of these lists on school literary literacy practices; the social, ethnic, gender, and sexual diversity they promote; how they move the school literary canon; and how they contribute (or can contribute) to a greater democratization of/in literary education. To this end, we select lists from the latest vestibular examinations of seven public universities, seeking to include institutions from all regions of Brazil. We consider reading lists to be an important tool for legitimizing authors and literary works in the school context. The proposed analysis is qualitative-interpretative (MOITA-LOPES, 1994; 2006) and understands that all literary literacy practices are ideological (STREET, 2014), which presupposes not only an investigation in dialogue with social contexts and with the various actors/agents around the literacy practices analyzed, but also an interpretation that does not isolate the research data from the power relations and discursive disputes exercised around them. From the observation that the inclusion promoted by these lists of literary works is limited only to certain diversities, we seek to analyze, especially, the absence of LGBTQIA+ authors and works, in order to understand the reasons for this absence and to demonstrate the educational potential that works and authors from these social groups could have in the construction of school literary literacies practices of re-existence (SOUZA, 2011; WALSH, 2009) for a transgressive (HOOKS, 2017) and democratic education.

Resumo O artigo objetiva descrever a experiência do curso Saúde e Segurança na Escola, que formou jovens para a multiplicação de saberes na prevenção de álcool e outras drogas, por meio da metodologia da educação entre pares. O curso teve a participação de 60 jovens do Ensino Médio, entre 15 e 19 anos, de oito escolas da rede pública do Distrito Federal. A atividade foi estruturada em oito módulos, sendo um encontro de debate de conteúdo; um segundo momento de atuação em campo nas escolas, em que os educandos fizeram a formação/multiplicação com seus colegas; e, por fim, um novo encontro para a devolutiva dos educandos a respeito da experiência no campo. Todas as atividades foram registradas em diários de campo, fotografias e relatórios, subsidiando o presente relato de experiência. Ao final, foi realizado um fórum de estudantes, no qual os jovens apresentaram os projetos a serem desenvolvidos nas escolas. A experiência de educação entre pares permitiu o protagonismo juvenil em sua comunidade escolar e em seu território, valorizando a troca entre pessoas com experiências semelhantes. Assim, viabilizou a elaboração de estratégias críticas e artisticamente potentes para ações de caráter preventivo direcionadas a adolescentes em situação de vulnerabilidade social, fomentando a promoção da saúde no ambiente escolar.

Abstract This article describes the experience of the course in Health and Safety at School, which prepared young people to spread knowledge on prevention of alcohol and other drugs, using the peer education methodology. The participants were sixty 15 to 19 year-old upper secondary school students from 8 public schools in the Federal District. The activity was structured into 8 modules, with each module consisting of a meeting to discuss content, followed by field work at the schools, where students trained their colleagues and passed on information to them; and, lastly, a further meeting for the students to give feedback on their experience in the field. All activities were recorded in field diaries, photographs, and reports, providing input to this experience report. Finally, a student forum was held at which the young people presented projects to be carried out at the schools. The peer education experience enabled the young people to take the lead in their school community and territory, and acknowledged the value of sharing among people with similar experiences. It thus favoured the development of critical, artistically potent strategies for preventive action directed to adolescents in situations of social vulnerability and fostered health promotion in the school.

ABSTRACT In Brazil, Anodontites trapesialis is a mussel species that occurs spontaneously in fish breeding sites. This species feeds on the remains of cultural treatments of other aquaculture species. The objective of the work is to understand the bromatological composition of mussel A. trapesialis. Individuals were selected to compose three samples of 500 g each of A. trapesialis for chemical composition, with viscera and viscera + shells being evaluated. The species presented 40.42 to 62.76 g of viscera per individual with a moisture content of 5.16% for viscera + shells and 86.5% for viscera. The mussel contains 42.6 and 12.96% crude protein, 3.16 and 1.76 of ether extract, 0.76 and 2.5% of crude fiber for viscera and viscera + shells. The total digestible nutrients were 74.16 and 36.96% for viscera and viscera + shells and 18.43 and 52.83% of mineral material for viscera and viscera + shells. A. trapesialis has relevant characteristics in its chemical composition as high protein content that gives the species potential for the human, animal, and other byproducts production.

Resumo O objetivo deste artigo é problematizar os impasses nas decisões sobre remoções e regularização fundiária a partir do papel das ações de planejamento urbano em assentamentos precários. A questão central é compreender os conflitos interescalares e os embates entre os modelos de desenvolvimento urbano e ambiental. Nosso objeto de estudo é o processo de remoção dos moradores do jardim Nova Esperança, em São José dos Campos-SP sob dupla perspectiva: o empreendedorismo municipal e o plano de urbanização e regularização fundiária como instrumento de negociação. Os impasses que resultam desses conflitos são analisados pela teoria dos atores com poder de veto, particularizando a tomada de decisão sobre o uso e a propriedade da terra diante das novas formas de ordenamento territorial.

Abstract The objective of this article is to problematize impasses in decisions about removals and land regularization based on the role of urban planning actions in precarious settlements. The central issue is to understand the inter-scalar conflicts and clashes between the models of urban and environmental development. Our object of study is the removal process of residents from the Jardim Nova Esperança settlement, in the city of São José dos Campos, State of São Paulo, under a double perspective: municipal entrepreneurship and the urbanization and land regularization plan as a negotiation instrument. The impasses that result from these conflicts are analyzed through the veto player theory, particularizing decision-making about land use and land ownership in view of new forms of territorial planning.

Resumo Introdução: Biossegurança é o conjunto de medidas aplicadas para prevenir a propagação de agentes infecciosos. Por meio da biossegurança é possível evitar e inibir os riscos que comprometem a saúde do indivíduo, dos animais e do meio ambiente. Objetivo: Avaliar o conhecimento sobre biossegurança de estudantes de graduação em fisioterapia e fisioterapeutas. Métodos: O trabalho foi uma pesquisa de campo com universo definido, e classificado como descritivo e exploratório-quantiqualitativo. A amostra foi composta por 93 alunos do curso de fisioterapia da Universidade Estadual do Norte do Paraná, em Jacarezinho, e 10 profissionais atuantes na região norte do Paraná. Os dados foram coletados por meio de um questionário sobre o conhecimento sobre biossegurança e infecções cruzadas. A análise estatística foi realizada no software SPPS versão 25.0 e os dados submetidos ao teste de normalidade Shapiro-Wilk, com as variáveis em mediana e intervalo interquartil (25% -75%). O teste qui-quadrado foi aplicado para buscar diferenças estatisticamente significantes entre os diferentes anos do curso de fisioterapia e os profissionais formados. Por meio da análise de conteúdo foram escolhidas questões abertas, tratamento e análise de dados qualitativos. O nível de significância adotado foi de 5%. Resultados: Constatou-se que existe um pequeno déficit no conhecimento em biossegurança, no entanto, esses conhecimentos de certa forma aumentaram com a evolução dos acadêmicos no curso (p < 0,05). Conclusão: A maioria dos estudantes e profissionais possui conhecimentos suficientes para controlar ou mesmo erradicar os riscos de determinadas atividades e evitar a infecção cruzada na prática da fisioterapia. O déficit de conhecimento em biossegurança constatado pode ser facilmente resolvido com a disseminação adequada do conhecimento sobre o assunto.

Abstract Introduction: Biosafety consists in the set of measures applied to prevent the spread of infectious agents. Through biosafety, it is possible to avoid and inhibit the risks that compromise the health of the individual, animals and the environment. Objective: To evaluate the knowledge about biosafety in undergraduate physiotherapy students and physiotherapists. Methods: The work was a field study with a defined universe, and classified as descriptive, exploratory, quantitative-qualitative. The sample consisted of 93 physiotherapy students from the Universidade Estadual do Norte do Paraná (State University of Northern Paraná), Jacarezinho, Brazil, and 10 professionals working in the region. Data were collected through a questionnaire on knowledge about biosafety and cross-infections. A statistical analysis was performed using SPPS software version 25.0, and the data was evaluated by the Shapiro-Wilk normality test, and the variables expressed as median and interquartile range (25% -75%). The chi-square test was applied to determine statistically significant differences between the different years of the physiotherapy course and the trained professionals. Through content analysis, open treatment and analysis of qualitative data were chosen. The level of significance used was 5%. Results: There was a small deficit in the knowledge of biosafety; however, this knowledge increased to some extent with the evolution of students in the course (p < 0.05). Conclusion: Most students and professionals have enough knowledge to control or even eradicate the risks of certain activities and prevent cross-infection in the practice of physiotherapy. The perceived deficit in knowledge in biosafety can be easily resolved with the adequate dissemination of knowledge on the subject.
