Abstract: En | Text: En | PDF: En

ABSTRACT The resistance of a weed to a herbicide may be accompanied by an ecological disadvantage, which can hinder the establishment of resistant biotypes when the herbicide is not used. The aim of this study, therefore, was to evaluate the growth and phenology of two biotypes of Raphanus raphanistrum, one susceptible and the other resistant to ALS inhibitors. The research was carried out from August to December 2020, conducting two simultaneous experiments, with the susceptible and resistant biotypes grown as single crops or together with wheat. The parameters under evaluation were plant height, number of leaves, leaf area, shoot dry weight, growth rate, leaf area ratio, net assimilation rate, and phenology - determined using the BBCH scale. The results showed not only that development and growth in the sensitive biotype was greater compared to the resistant biotype, but also the precocity of the biotype. The only variable for which the resistant biotype was superior was root dry weight. Cross-resistance to ALS inhibitors resulted in a difference in the growth and phenology of the resistant biotype that should be better evaluated, as the populations present large genetic differences.

Abstract: En | Text: En | PDF: En

Abstract The aim of this study was to investigate uterine involution using ultrasonography techniques during postpartum. Postpartum ultrasonography evaluation (B-mode, color Doppler and Acoustic Radiation Force Impulse elastography) of the uterus was performed by transabdominal approach at immediate after birth and sequentially every 48 hours, during 30 days. The uterine echotexture did not present significant variations (P >0.05) being homogeneous in most evaluations; echogenicity of the uterus increased along the evaluation period (P =0.0452). Progressive and remarkable decrease of the total uterine diameter (UD) were observed (P <0.0001), especially during the first days postpartum. The thickness of uterine wall gradually decreased, as well the endometrial, myometrium and lumen diameters (P <0.0001). Uterine blood flow was assessed by Doppler and decreased during postpartum period, being significantly lower (P=0.0225) on the 30th day of postpartum. Uterine parenchyma presented as homogeneous dark areas (not deformable) on qualitative ultrasound elastography and the means shear velocity values of the uterine wall on quantitative elastography did not differ. This is the first study that evaluate the stiffness of uterine wall in healthy ewes, providing baseline data about quantitative and qualitative stiffness of the normal uterus, and it may be a useful tool for early diagnosis of uterine alterations during the postpartum period, using the reference parameter established for the assessment of uterine integrity during postpartum period.

Abstract The objective of this study was to obtain data on the testicular biometry of the white-lipped peccary (Tayassu pecari) and to verify if there is a correlation between the individual’s biometric data with their dominance rank. Data were collected from 16 adult males, aged between two and seven years, who made up the same group. By the agonistic interactions analyses we calculated the linearity indexes (h') of the dominance hierarchy and dominance rank. At the end of the behavioral observations, males were captured to collect biometric data from the testis. White-lipped peccaries showed testicles located in a perineal position, inclined cranio-ventrally with oval shape, flattened laterally and with tenso-elastic consistency (2.54±0.07). There was variance in the means (± standard deviation) of testis length (5.88±1.05cm), width (4.24 ± 0.98cm), height (4.44±0.86cm), and total scrotal width (8.78±17.05). The linear dominance hierarchy described the social structure of the males of this group (h'>0.9), with probability of linearity in the hierarchy greater than chance (P = 0.02). There was a correlation between dominance rank with the body mass, length and volume of the testicles. As in general the dimensions of the testicles are directly correlated with sperm production and also testosterone, this characteristic favors the reproductive performance of dominant white-lips males. Therefore, the characteristics of testicular biometry of white-lips should be considered for the selection of individuals more likely to reproduce in captivity favoring the conservation of this vulnerable species.

Resumo O objetivo neste estudo foi obter dados sobre a biometria testicular do queixada (Tayassu pecari) e verificar se há correlação entre os dados biométricos do indivíduo com seu posto de dominância. Os dados foram coletados de 16 queixadas adultos, com idades entre dois e sete anos, que compunham o mesmo grupo. Por meio de análises das interações agonísticas foram calculados os índices de linearidade (h') da hierarquia de dominância e determinado o rank dos indivíduos. Ao final das observações comportamentais, os machos foram capturados para coleta de dados biométricos do testículo. Os queixadas apresentaram testículos localizados em posição perineal, inclinados cranioventralmente com formato oval, achatados láterolateralmente e com consistência tensoelástica (2,54±0,07). Houve variação nas médias (± desvio padrão) do comprimento testicular (5,88±1,05cm), largura (4,24±0,98cm), altura (4,44±0,86cm) e largura escrotal total (8,78±17,05). A hierarquia de dominância linear descreveu a estrutura social dos machos desse grupo (h'>0,9), com probabilidade de linearidade na hierarquia maior que o acaso (P = 0,02). Houve correlação entre a classificação de dominância com a massa corporal, comprimento e volume dos testículos. Como em geral as dimensões dos testículos estão diretamente correlacionadas com a produção de esperma e também de testosterona, essa característica favorece o desempenho reprodutivo de machos de queixadas brancos dominantes. Portanto, as características da biometria testicular de queixadas devem ser consideradas para a seleção de indivíduos com maior probabilidade de reprodução em cativeiro favorecendo a conservação desta espécie vulnerável.

ABSTRACT Healthcare financing is attracting widespread interest due to the coronavirus pandemic. This study aims to assess federal public healthcare financing in Brazil in the light of a legal framework for minimum spending on health and the effects of economic cycles and crises. A literature review showed that public healthcare funding should increase during crises, which is contrary to what fiscal austerity policies postulate. Different formats of fiscal rules for minimum spending on health are analyzed based on the historical evolution of healthcare financing in Brazil. A simulation shows that linking this spending rule to GDP (and especially to current revenue) gives a pro-cyclical character to healthcare financing, which can make it difficult to guarantee health rights in times of crisis. Thus, a debate arises about the need to revise the rule set by the Constitutional Amendment 95/2016 (EC no. 95/2016) and to establish a parameter for growth in public healthcare expenditure that eliminates its pro-cyclical characteristic and enables the needs of the country to be met after the pandemic.

RESUMO O financiamento de sistemas de saúde tem atraído amplo interesse devido à pandemia de coronavírus. Este artigo propõe uma avaliação do financiamento do sistema de saúde público no Brasil para o governo Federal à luz da legislação para gasto mínimo em saúde e dos efeitos de ciclos econômicos e crises. A partir de uma revisão da literatura, é indicado que, em momentos de crise, o financiamento do sistema público de saúde deva aumentar, contrário ao que as políticas de austeridade fiscal postulam. Diferentes formatos de regras fiscais para o gasto mínimo em saúde são analisados com base na evolução histórica do financiamento de saúde pública no Brasil. Uma simulação mostra que vincular essa regra de gasto ao PIB, e, principalmente, à receita corrente, atribui um caráter pró-cíclico ao financiamento do sistema público de saúde, o que dificulta a garantia do direito à saúde em momentos de crise. Assim, emerge o debate sobre a necessidade de revisar a regra estabelecida pela Emenda Constitucional nº 95/2016 e definir uma regra de crescimento para o gasto no sistema público de saúde que elimine o traço pró-cíclico e permita que as necessidades pós-pandemia do país sejam atendidas.

ABSTRACT Introduction: it is estimated that approximately 20 million people undergo inguinal hernia surgery annually in the world, with the Lichtenstein technique being the most performed surgical procedure. The objective of this study is to analyze the knowledge of the technical principles used in the Lichtenstein technique. Method: Survey-type intersectional study approved by the research ethics committee of São Camilo University Center (CAAE: 70036523.1.0000.0062). During the research period, 11,622 e-mails were sent to members of the main national surgical societies with research on the technical principles of Lichtenstein surgery. The survey was carried out using an electronic form with 10 multiple-choice questions. The form was answered anonymously on the SurveyMonkey and Google Forms platforms. Result: 744 responses were received to the electronic form. Based on this number of respondents, our survey has a confidence level of 95% with a margin of error of 3.5%. It was observed that there is no standardization of the technique among the majority of responders (53.4%). Many surgeons still perform digital dissection of the spermatic cord (47%). A small number of interviewees (15.2%) performed sutures with absorbable thread in the region of the internal oblique aponeurosis, while more than half (55.2%) continued to perform sutures with non-absorbable thread. Most surgeons use a small overlap or fix the mesh juxtaposed to the pubic symphysis (51%). Conclusion: Our research identified that a small percentage of respondents adequately know the technical principles of Lichtenstein surgery. The result brings us new insights into the need to review Lichtenstein technique.

RESUMO Introdução: estima-se que aproximadamente 20 milhões de pessoas sejam submetidas a cirurgia de hérnia inguinal anualmente no mundo, sendo a técnica de Lichtenstein o procedimento cirúrgico mais realizado. O objetivo desse estudo é analisar o conhecimento dos principios técnicos empregados na técnica de Lichtenstein. Método: estudo tipo levantamento interseccional aprovado pelo comitê de ética em pesquisa do Centro Universitário São Camilo (CAAE: 70036523.1.0000.0062). Durante o período da pesquisa foram encaminhados 11.622 e-mails aos membros das principais sociedades cirúrgicas nacionais com uma pesquisa sobre os princípios técnicos da cirurgia de Lichtenstein. A pesquisa foi realizada por formulário eletrônico com 10 questões de múltipla escolha. O formulário foi respondido de forma anônima nas plataformas SurveyMonkey e Google Forms. Resultado: foram recebidos 744 respostas ao formulário eletrônico. Com base nesse número de respondedores, nossa pesquisa apresenta grau de confiança de 95% com margem de erro de 3,5%. Foi observado que não há padronização da técnica entre a maioria dos respondedores (53.4%). Muitos cirurgiões ainda fazem dissecção digital do funículo espermático (47%). Um pequeno número de entrevistados (15,2%) realizam sutura com fio absorvível na região da aponeurose do obliquo interno, enquanto, mais da metade (55,2%) continua fazendo sutura com fio inabsorvível. A maior parte dos cirurgiões utilizam overlap pequeno ou fixam a tela justaposta a sínfise púbica (51%). Conclusão: nossa pesquisa identificou que uma porcentagem pequena dos entrevistados conhecem adequadamente os princípios técnicos da cirurgia de Lichtenstein. O resultado nos traz novas percepções sob a necessidade de revistar a consagrada técnica de Lichtenstein.

RESUMO Este artigo tem o objetivo de avaliar e comparar o impacto distributivo das faixas de imposto de renda sobre pessoa física na China e no Brasil estimando o Coeficiente de Gini antes e depois da aplicação desse imposto. O artigo também estabelece uma metodologia para transpor as faixas de imposto de renda entre esses dois países. Os resultados mostram que faixas mais progressivas realizadas pela China, com maior número de alíquotas e com taxa marginais mais elevadas, não garantem maior redução da desigualdade. Argumentamos que isso ocorre devido à alta faixa de isenção e às baixas alíquotas das primeiras faixas, que acabam reduzindo a taxa efetiva para a maioria da população chinesa, incluindo aqueles considerados ricos dentro da distribuição de renda desse país. Com isso, percebe-se que as alíquotas de IRPF desses dois países merecem revisões caso busquem cumprir melhor a sua função distributiva. elevadas desigualdade chinesa país percebese percebe se distributiva

ABSTRACT This paper aims to evaluate and compare the distributive impact of the personal income tax (PIT) on individual’s income in Brazil and China by measuring the Gini Index before and after this tax incidence. The paper also proposes a methodology for transposing the PIT backets from one country to another. The results show that a more progressive scheme implemented by China, with more brackets and higher rates, does not guarantee reduction of inequality, due to the level of income exemption and to the incomes on which the marginal rates affect. Thus, it can be perceived that the PIT brackets of these two countries deserves revisions if they seek to fulfill the distributive function.

Resumo Fundamento A incidência de ductus arteriosus patente (PCA) pode chegar a 50% em pacientes prematuros. Quando hemodinamicamente significativo, pode ser responsável por tempo de ventilação mecânica prolongado, além de importante fator de risco para o aparecimento de enterocolite necrotizante, hemorragia intraventricular e displasia broncopulmonar nessa população. Objetivo O objetivo deste estudo é descrever a experiência inicial do fechamento percutâneo de canal arterial em prematuros pesando menos de 2 kg. Métodos Trata-se de estudo prospectivo que compreendeu 14 pacientes consecutivos submetidos a fechamento percutâneo de canal arterial de março de 2020 a fevereiro de 2021 em 6 instituições no Brasil. Resultados A idade gestacional média ao nascimento foi de 28,45 ±3,14 semanas, a idade média no momento do procedimento foi de 38,85 ±17,35 dias e o peso médio de 1,41±0,41 kg. Dentre os prematuros, 79% necessitavam de ventilação mecânica e 79% tinham feito uso de, em média, 1,5 ciclos de anti-inflamatórios não esteroides. A maioria dos pacientes teve melhora dos parâmetros ventilatórios e o tempo médio de extubação foi de 12,6 ±7,24 dias. A taxa de sucesso foi de 100%. Não houve mortalidade relacionada ao procedimento. Conclusão Este estudo concluiu que o fechamento percutâneo do canal arterial em prematuros é uma realidade no Brasil, com resultados satisfatórios e baixa taxa de complicações.

Abstract Background The presence of patent ductus arteriosus can be as high as 50% in preterm babies. Hemodynamically significant patent ductus arteriosus is a common cause of delayed weaning of respiratory support and an important risk factor of necrotizing enterocolitis, intraventricular hemorrhage, and bronchopulmonary dysplasia in this population. Objective The aim of this study is to describe an initial experience of percutaneous closure of the ductus arteriosus in preterm infants weighing less than 2 kg. Methods This was a prospective study, comprised of 14 consecutive patients submitted to percutaneous closure of ductus arteriosus between March 2020 and February 2021 in 6 institutions in Brazil. Results Mean gestational age was 28.45±3.14 weeks, mean age at the procedure was 38.85±17.35 days and mean weight was 1.41 ±0.41 kg; 79% of the patients were under mechanical ventilation, and 79% had been submitted, on average, to a 1.5 cycle of non-steroidal anti-inflammatory drugs. Most patients were weaned off of mechanical ventilation in a mean of 12.6 ±7.24 days after the procedure. Success rate was 100%. No procedure-related mortality was observed. Conclusion This study concluded that percutaneous closure of ductus arteriosus in premature babies below 2 kg has satisfactory results and a low complication rate in this study sample.

Resumo O objetivo do artigo é avaliar a evolução recente do acesso da população brasileira à educação superior assim como o perfil dos estudantes tendo em vista o conjunto de políticas públicas direcionadas para a educação superior. Os dados mostram que, de 2001 a 2015, houve ampliação da representatividade dos negros, do número de estudantes em Unidades da Federação fora do eixo Sul-Sudeste-Brasília e do percentual de estudantes de renda baixa. Adicionalmente, busca-se mostrar que esse processo de inclusão pode estar ameaçado por políticas de austeridade, em especial a Emenda Constitucional 95.

Abstract The objective of this paper is to evaluate the recent evolution of the access of the Brazilian population to higher education as well as the profile of students considering a set of public policies directed to higher education. The data show that, from 2001 to 2015, there was an increase in the representation of black students, as well as an increase in the number of students in Federation Units outside the South-Southeast-Brasilia axis and the percentage of low-income students. Additionally, the article discusses that the process of inclusion may be threatened by austerity policies, especially the Constitutional Amendment 95.

Abstract Direct oral anticoagulants have emerged as the drugs that have changed the man agement of the antithrombotic treatment in the last 15 years. Their advantages, like a more friendly way of anticoagulation and their lower risk of bleeding, especially in the brain, have positioned these new anticoagu lants as the first drug of choice in the two most frequent indications of anticoagulation, atrial fibrillation, and the venous thromboembolic disease. However, not all the patients can receive these agents, not all the direct oral anticoagulants have the same characteristics, and most importantly, not all the diseases with an indication of an anticoagulant drug can be treated with them. Therefore, it is mandatory that all the faculties involved in the management of these drugs must know them in depth, to decide the best treatment for the patient. This position paper, from a group of experts in anticoagulation in Argentina, can help the general practitioner in the daily use of direct oral anticoagulants based on the new evidence and the experience of a wide group of professionals. The way we relate to the anticoagulant treatment has changed in the last years. The doctors who work with them must also do so.

Resumen Los anticoagulantes orales directos han surgido como una de las herramientas que ha cambiado el manejo de la enfermedad trombótica en los últimos 15 años. Sus ventajas, desde el punto de vista de la facilidad de uso y menor riesgo de sangrado, especialmente de sangrado cerebral, han posicionado a estos nuevos anticoagulantes como la primera alternativa de tratamiento en las dos indicaciones más frecuentes en que necesitamos estas drogas, la fibrilación auricular y la enfermedad tromboembólica venosa. Sin embargo, no todos los pacientes pueden recibir estos agentes, no todos los anticoagulantes directos tienen las mismas pro piedades y fundamentalmente, no todas las enfermedades con indicación de un anticoagulante pueden tratarse con ellos;con lo cual es necesario que todos los profesionales que están involucrados en el manejo de estos medicamentos estén obligados a conocerlos en profundidad, para poder decidir el mejor tratamiento en cada caso particular. Este documento de posición de expertos de diferentes especialidades de Argentina, presenta lineamientos para el uso correcto de los anticoagulantes directos en base a nueva evidencia y a la experiencia de uso de un amplio grupo de profesionales. La forma de relacionarnos con el tratamiento anticoagulante ha cambiado. Los médicos que trabajamos con ellos también debemos hacerlo.

Abstract: En Pt

Objective: to identify the evidence related to the risks of SARS-CoV-2 exposure in healthcare workers and the interventions adopted. Method: systematic literature review in eight scientific databases and three gray literature repositories. Results: 26 studies identified as risk factors: scarcity, inadequate use or reuse of personal equipment; low adherence to precautionary measures; working in intensive care and COVID-19 sectors; long stay in a closed work environment; sharing eating areas without the use of masks and distance; low knowledge and unpreparedness for disease management. 12 studies identified as interventions: health surveillance programs with early detection, diagnosis and early withdrawal; organization of care flows; double triage; telemedicine; limitation of visits; creation of exclusive sectors for care to COVID-19; qualification and training with virtual tools and simulation. Conclusion: besides the risk of infection, individual, psychosocial and organizational factors made the healthcare work environment unsafe. Interventions should be adopted to mitigate the risks and decrease the professionals' morbidity and mortality.

Objetivo: identificar as evidências relacionadas aos riscos de exposição ao SARS-CoV-2 em profissionais de saúde e as intervenções adotadas. Método: revisão sistemática de literatura em oito bases de dados científicas e três repositórios de literatura cinzenta. Resultados: 26 estudos identificaram como fator de risco: escassez, uso inadequado ou reuso de equipamentos individuais; baixa adesão às medidas de precaução; atuação em terapia intensiva e setores COVID-19; longa permanência em ambiente de trabalho fechado; compartilhamento de espaços para alimentação sem uso de máscara e distanciamento; baixo conhecimento e despreparo para atendimento à doença. 12 estudos identificaram como intervenções: programas de vigilância em saúde com detecção precoce, diagnóstico e afastamento precoce; organização de fluxos de atendimento; triagem dupla; telemedicina; limitação de visitas; criação de setores exclusivos para atendimento à COVID-19; capacitações e treinamentos com ferramentas virtuais e simulação. Conclusão: além do risco de infecção, fatores individuais, psicossociais e organizacionais tornaram o ambiente de trabalho em saúde inseguro. Intervenções devem ser adotadas para mitigar os riscos e diminuir a morbimortalidade dos profissionais.

Abstract: En | Text: En | PDF: En

Ti-34Nb-6Sn alloy were prepare by powder metallurgy milled in two different times (40 and 60 min) using Ti and Nb hydrides with or without Mg, as spacer then sintered at 700ºC and 800ºC. Characterizations were made by scanning electron microscope (SEM), X-ray diffractometer (XRD) and by Archimedes. Microhardness was measured by Vickers microhardness. Mesenchymal stem cells derived from equine bone marrow (BMMSCs) were used to evaluate the sample cytotoxicity. Hydration and dehydration process was confirmed, also the formation of brittle particles during the milling. Materials were structured under α and β phase, and the samples that received Mg as a spacer had slightly lower β phase content compared to samples without Mg, suggesting difficult α→β transformation due to the presence of barriers formed by pores. Mg provided greater porosity, and prepared milled in a shorter time promoted an increase in the macropores. Microhardness was similar to that of commercial materials (i.e., CP-Ti and also to other alloys with similar nominal composition. Cells treated with conditioned medium with the samples showed viability comparable to the control group, and after 48 h of culture on the samples, there was significant growth and more circular morphology, when adhered on materials that received Mg.

ABSTRACT. The aim of this study was to evaluate the influence of weaning and concentrate supplementation on the characteristics of carcass cuts and longissimus muscle of Suffolk lambs finished on a Tifton 85 (Cynodon spp.) pasture. Weaning and concentrate supplementation strategies were evaluated in four finishing systems: i) non-weaned and non-supplemented lambs; ii) non-weaned lambs supplemented with concentrate in creep feeding; iii) weaned and non-supplemented lambs; and iv) weaned lambs supplemented with concentrate. In the systems with weaning, lambs were weaned at 46 ± 6 days of age. In the systems with supplementation, the concentrate was offered daily at 2% of lambs’ body weight. Weaning led to a decrease, whereas supplementation led to an increase in carcass cut weights. Supplemented lambs had lower yields of neck and uncovered ribs, and higher yields of breast + flank and loin. The characteristics of loin eye and fat thickness over the longissimus muscle presented lower values in weaned lambs and higher values in supplemented lambs. Keeping lambs with their dams and offering concentrate supplementation until slaughter are strategies recommended to obtain heavier cuts with increased muscularity and fat content.
