Dispersion and aggregation of nanoparticles in aqueous solutions are important factors for safe and effective application of nanoparticles, for instance, in the oil industry. As conventional oil reserves are depleted, it is necessary to advance chemical enhanced oil recovery (cEOR) techniques to develop unconventional oil reservoirs. Nanoparticles modified by surfactants can be a promising reagent in cEOR. These nanomaterials can reduce interfacial tension and change the wettability of reservoir rock, which leads to an increase in oil recovery. However, the application of nanoparticles is limited by their substantial aggregation in aqueous solutions. The purpose of this work is to select nanoparticles for obtaining stable sols in water in the presence of an anionic surfactant and to optimize the conditions (pH) for further modifying the nanoparticles with the anionic surfactant. Sodium dodecyl sulfate (SDS) is used as an anionic surfactant. The aggregation of oxide and carbon nanoparticles in water and anionic surfactant solutions was studied by laser diffraction, dynamic and electrophoretic light scattering methods. Most of the studied nanoparticles in water form aggregates with bi-, three- and polymodal particle size distributions. TiO2 nanoparticles obtained by plasma dynamic synthesis form the most stable sols in anionic surfactant solutions. The range of 5–7 pH is defined as optimal for their modification with surfactants. The stability of carbon nanoparticles in aqueous solutions increases significantly in the presence of a surfactant. The obtained results form the basis for further research on the modification of marked nanoparticles in surfactant solutions.

RESUMO Objetivos: comparar as prevalências de aleitamento materno exclusivo versus aleitamento artificial em recém-nascidos de mães com COVID-19. Métodos: revisão sistemática de prevalência, segundo JBI. Buscas nas bases PubMed®, Embase, CINAHL, LILACS e Web of Science™ em agosto de 2021. Selecionados estudos transversais, longitudinais ou coortes, sem limitação de idioma e tempo que apresentavam prevalência de aleitamento materno ou que permitissem o cálculo. Resultados: 15 artigos publicados em 2020 e 2021, coortes (60%) ou transversais (40%) foram analisados. A média de aleitamento materno exclusivo em mães com COVID-19 foi 56,76% (IC=39,90–72,88), e artificial, de 43,23% (IC = 30,99 – 55,88), sem diferenças estatisticamente significantes. Conclusões: apesar das recomendações para a manutenção do aleitamento materno, houve redução mundialmente, quando comparados à períodos anteriores à pandemia. Com avanços da ciência, esses índices têm melhorado, mostrando o impacto das evidências nas práticas. Como limitações, citam-se fontes dos estudos. Recomenda-se realização de novos estudos.

ABSTRACT Objectives: to understand practices of mothers of children in early childhood who live in contexts of poverty in the face of the COVID-19 pandemic. Methods: an exploratory, descriptive and qualitative study. Participants were selected in the community context, composing an intentional sample to be collected through semi-structured online interviews. Data were analyzed inductively and anchored in the Bioecological Model of Human Development. Results: eight mothers participated in the research. Mothers highlighted pleasure in taking care of their children, although they were overloaded with activities and comprehensive care at the time of the pandemic. Children, in mothers’ perception, showed a higher frequency of challenging behaviors, which may be related to negative parenting practices, such as punishment and physical violence. Final Considerations: interventions to support parenting become urgent in the face of changes brought about by the COVID-19 pandemic in families living in a context of poverty.

RESUMO Objetivo: o objetivo deste estudo foi criar um novo modelo animal de indução de aderências peritoneais capaz de levar à formação de aderências em todos os animais operados, simples e reprodutível, associado a manutenção da saúde dos animais. Métodos: Dezoito ratos machos, adultos, da linhagem Wistar (Rattus norvegicus) foram distribuídos aleatoriamente em três grupos: Grupo Controle (parâmetro anatômico e clínico), Grupo Sham (manipulação delicada do estômago e exposição de cavidade peritoneal ao ar ambiente) e Grupo Cirurgia (gastrotomia seguida de gastrorrafia). Os animais foram submetidos à análise e classificação macroscópicas, seguindo dois modelos de classificação de aderências. As diferenças entre os grupos foram consideradas estatisticamente significantes se p<0,05. Resultados: os seis animais do grupo controle não apresentavam aderências peritoneais, três dos seis animais do grupo sham apresentavam aderências peritoneais focais e todos os seis animais do grupo cirurgia (gastrotomia seguida de gastrorrafia) apresentavam aderências peritoneais firmes. Todas as aderências encontradas foram quantificadas macroscopicamente e confirmadas microscopicamente, sem a realização de classificação microscópica das aderências. Conclusão: o novo modelo desenvolvido, de gastrotomia seguida de gastrorrafia, mostrou-se seguro e eficiente para induzir e estudar aderências peritoneais.

ABSTRACT Introduction: this paper aims to evaluate the main direct and indirect costs of the first laparotomies and laparoscopies in bariatric surgeries with a clinical-economical retrospective and cross-sectional analysis from 2017 to 2020 at a hospital with specialties besides the basic ones in southern Brazil. Methods: the study sample included 26 participants. The first 13 laparotomies, and the first 13 laparoscopies performed at the bariatric surgery service of the institution were evaluated. The values evaluated in such comparison analyzed the costs of operation and hospitalization. It is important to highlight that, in addition to the cost benefit, other costs take significance in the health area, such as: cost-utility, cost-effectiveness and cost-minimization, in addition to the cost-opportunity that is reassessed in the observation of the broad context associating all the values raised here. The software used for data analysis was Excel version® 365. The economic analysis was performed evidencing the profile of the patients and the direct and indirect costs involved in each segmentation. Results: the direct and indirect costs of videolaparoscopy amounted to BRL 10,108.10 and laparoscopy to the amount of BRL 12,568.14. Conclusion: it was concluded that laparoscopy presents more savings in the aspects of all health valuations to the detriment of laparotomy. It was concluded that the videolaparoscopy presents more savings in the aspects of all health valuations than the laparotomy.

RESUMO Introdução: obesidade é uma das doenças mais comuns do mundo e a cirurgia bariátrica é o tratamento mais eficaz até o momento. Um dos impactos negativos do procedimento é o dismorfismo corporal causado pelo excesso cutâneo. No Brasil, o Sistema Único de Saúde (SUS) promove cirurgia de contorno corporal para tratar pacientes com perda ponderal maciça desde 2007. Este artigo tem como objetivo descrever a abordagem do SUS para pacientes pós-bariátricos através de análise do banco de dados do próprio sistema. Métodos: foi realizada pesquisa no banco de dados do SUS para procedimentos em pós-bariátricos entre 2007 e 2021. As variáveis analisadas foram localização geográfica, ano, tempo médio de internação, morte e taxa de mortalidade. Também analisamos o número de procedimentos bariátricos realizados no mesmo período. Análise estatística foi realizada utilizando os testes t de Student e do Qui-Quadrado, considerando valor p<0,5 como significante. Resultados: um total de 12.717 procedimentos de cirurgia plástica foram realizados em pacientes pós-bariátricos, com prevalência nacional de 13,8%. Dermolipectomia foi o procedimento mais realizado, com um total de 6.719. Nos anos de 2020 e 2021 houve um decréscimo de 64,3 e 70,9% no total de cirurgias, respectivamente (p<0,001). Procedimentos bariátricos tiveram maior número total e taxa de crescimento maiores do que cirurgia pós-bariátricas (p<0,001), totalizando 93.589 cirurgias. Conclusões: houve um número significativo de cirurgias de contorno corporal no Brasil, embora com baixa prevalência. Dermolipectomia foi o procedimento mais realizado. Notamos impacto significativo da pandemia Sars-CoV-2 no total de procedimentos realizados.

RESUMO: Neste artigo, é apresentado um estudo que se propõe a identificar, de forma quantitativa, habilidades cognitivas, de domínio geral e específico, como preditoras do desempenho aritmético de 127 alunos de 3º e 4º anos do ensino fundamental. Os participantes foram avaliados nas habilidades de memória de trabalho, consciência fonêmica, compreensão leitora, transcodificação numérica, estimativa numérica e raciocínio quantitativo. Essas habilidades cognitivas foram avaliadas em dois momentos, no início e no final do ano letivo, sendo, nesse segundo momento, também avaliado o desempenho aritmético dos estudantes. Os resultados indicaram uma influência direta especificamente da transcodificação numérica, do raciocínio quantitativo e da consciência fonêmica no desempenho aritmético. Além disso, os achados mostraram que a transcodificação numérica é uma habilidade mediadora da relação das habilidades de raciocínio quantitativo e consciência fonêmica com a habilidade aritmética. Com isso, ressalta-se a importância de habilidades de domínio geral e específico para o desempenho aritmético dos estudantes. Destaca-se também a priorização do ensino pautado na compreensão do sistema numérico e das relações entre quantidades (raciocínio quantitativo) para a aprendizagem aritmética, bem como para a prevenção de dificuldades matemáticas futuras.

RESUMO A relação universidade-sociedade, chamada terceira missão universitária, está em constante mudança, na tentativa de acompanhar as demandas sociais, econômicas e culturais. Mensurar as atividades da universidade e compartilhar com a sociedade é atender aos princípios da governança, como transparência, prestação de contas e responsabilidade. Este artigo objetiva identificar possíveis indicadores da terceira missão universitária e os principais conceitos e construtos relacionados ao tema. Embora similares, a pesquisa diferencia os conceitos “terceira missão” (conceito europeu) e “extensão” (conceito latino-americano), em função do portfólio de seus indicadores e do alcance dos termos. Desenvolveu-se uma revisão sistemática de literatura (RSL) e da análise bibliométrica, por meio do método Systematic Search Flow (SSF). Conclui-se que mensurar as atividades da terceira missão universitária e seus impactos sociais, apesar de todos os esforços acadêmicos e governamentais, não é uma tarefa fácil. A dificuldade está nas múltiplas atividades e interpretações do que é a terceira missão. Porém, como resultado da pesquisa, serão apresentados os principais indicadores que abarcam o tema.

ABSTRACT: The university-society relationship, called the third university mission, is constantly changing in an attempt to keep up with social, economic and cultural demands. Measuring the university's activities and sharing it with society is to meet the principles of governance, such as transparency, accountability and responsibility. This article aims to identify possible indicators of the third university mission and the main concepts and constructs related to the theme. Although similar, the research differentiates the concepts 'third mission' (European concept) and 'extension' (Latin American concept) according to the portfolio of their indicators and the scope of the terms. A systematic literature review (RSL) and bibliometric analysis were carried out using the Systematic Search Flow (SSF) method. It is concluded that measuring the activities of the third university mission and its social impacts, despite all academic and governmental efforts, is not an easy task. The difficulty lies in the multiple activities and interpretations of what the third mission is, however, as a result of the research the main indicators that cover the theme will be presented.

ABSTRACT: In this article, we analyze the effects of two affirmative action policies adopted by the Federal University of Minas Gerais (UFMG): the bonus policy and the Quota Act. We compare the social inclusion produced by them by two angles: the access itself to UFMG and the distribution of the target groups among the institution’s programs, considering its internal horizontal hierarchy. We verify the changes in the student`s profile by focusing on three variables: race, school origin and family income. Based on descriptive statistics, it is concluded that the two policies had relevant effects on social inclusion. However, this occurred in different ways. The bonus policy was able to increase the access of students from public schools, blacks and with low-income, but mainly in the less selective programs. The Quota Act contributed more effectively to increasing the access of these students to the most selective programs of UFMG, reducing the horizontal inequalities. We observe, however, that remains expressive inequalities in the access to the universities programs still need to be addressed.

RESUMO: Este artigo apresenta uma revisão da literatura sobre relatos acerca de pessoas com autismo em pesquisas realizadas nos campos da Educação, Psicologia, Medicina e Enfermagem. Foram coletados 22 artigos na base de dados SciELO, entre os anos de 2008 e 2021, a partir das palavras-chave autismo e entrevistas. Os dados foram analisados pela técnica da Análise de Conteúdo (BARDIN, 2016), com o auxílio do software ATLAS.ti. As categorias levantadas - diagnóstico e saúde; educação; e relações familiares - foram discutidas a partir das perspectivas teórico-metodológicas de Vygotsky (2003) e Bronfenbrenner (1996). Tal análise permitiu relacionar as questões pessoais com as sociais, tomando por base as relações socio-históricas e bioecológicas que envolvem a vida dos sujeitos com autismo. Os resultados apontam para a interferência entre a insuficiência de oferta de serviços e políticas de suporte social e o desenvolvimento dessas pessoas; a importância da escola e a deficitária formação docente; e as repercussões desse desenvolvimento nas rotinas familiares, sobretudo na vida da figura materna.

RESUMO: A finalidade deste estudo é mapear a atual situação das pesquisas no ensino de engenharia sob a perspectiva da sustentabilidade, os pacotes de bibliometrix e biblioshiny foram empregados para realizar a mineração de dados e análise quantitativa de publicações nessa área do conhecimento entre 2012 a 2022 no banco de dados da Web of Science. Os resultados demonstraram que nos últimos 10 anos, o número de artigos sobre o ensino de sustentabilidade na engenharia aumentou. O aumento foi gradativo e pode ser divididas em três etapas, entre 2012 e 2016 as publicações oscilaram de 130 a 150, de 2017 a 2019 as publicações passaram de 150 a 190 e de 2020 a 2021 superaram os 200 artigos. Os principais países e regiões em termos de desenvolvimento de pesquisas na área de ensino de sustentabilidade na engenharia são os Estados Unidos, Espanha, China, Austrália, Reino Unido, Alemanha, Canadá e Itália, além de serem os países importantes para a cooperação internacional nessa área. Desenvolvimento sustentável, educação em engenharia, estudantes, educação, currículo, ensino e sustentabilidade foram as palavras-chaves mais citadas nessa área nos últimos 10 anos. Dentro desse campo despontam como temas de pesquisas o emprego das metodologias ativas, desenvolvimento sustentável, boas práticas pedagógicas e de sustentabilidade, além da construção de competências e habilidades. O ensino de sustentabilidade na engenharia é uma temática relativamente nova, entretanto, devido a urgência do tema muitos estudos foram desenvolvidos e muitos outros estão se desdobrando, todavia, a complexidade do tema não esgota as lacunas do assunto.
INSUBORDINAÇÕES CRÍTICAS DA INTELECTUALIDADE NEGRA BRASILEIRA: UM OLHAR A PARTIR DA ATUAÇÃO DO NEABI/CPII

Published: July 2023

RESUMO: Partindo de uma perspectiva negra decolonial (GOMES, 2020), este artigo tem como objetivo discutir os caminhos trilhados pelo Núcleo de Estudos Afro-Brasileiros e Indígenas do Colégio Pedro II (NEABI/CPII), no Rio de Janeiro, na (re)produção de práticas e conhecimentos emancipatórios e antirracistas. Em termos metodológicos, a pesquisa foi estruturada com base nas narrativas de quatro intelectuais negros/as comprometidos/as com a educação antirracista, que participaram ativamente do processo de criação do NEABI/CPII, em 2013, e que tiveram reconhecido protagonismo na constituição de práticas calcadas na (re)educação para as relações étnico-raciais e no combate ao racismo. Em suma, percebemos que a intelectualidade negra que compõe o NEABI/CPII situa-se em posição de insubordinação em relação às práticas típicas da colonialidade na (re)produção do conhecimento, com atuações que se desdobram em quatro dimensões: político-institucional, político-epistemológica, político-identitária e político-pedagógica. Entendemos que essas dimensões, que se articulam entre si, são cruciais para a constituição de espaços educativos que sejam mais democráticos, racialmente diversos e politicamente posicionados no combate às desigualdades.
ALFABETIZAÇÃO MIDIÁTICA-VISUAL: UM DIREITO HUMANO NA ESCOLA

Published: July 2023

RESUMO: O estudo versa sobre a relação entre a cultura da mídia e o território escolar, colocando em debate as compreensões e aptidões que os/as docentes possuem em relação às didáticas voltadas para a Alfabetização Midiática-Visual dentro de seus contextos escolares de atuação. Em termos metodológicos, trata-se de uma abordagem quanti-qualitativa, que tem como estratégia central a pesquisa-ação (THIOLLENT, 1986). Para isso, articula-se teórico-metodologicamente através de alguns conceitos, tais como: Direitos Humanos (MARTIN-BARBERO, 2011), Alfabetismo Visual (KELLNER, 1995) e Educação Midiática (BACCEGA, 2001). Noções essas que nortearam a pesquisa empírica desenvolvida com um grupo de docentes da rede municipal de uma cidade no Rio Grande do Sul/Brasil. O trabalho é oriundo de um processo investigativo de sondagem introdutória, que seguiu com uma abordagem focal. Entre os resultados da pesquisa-ação, verificou-se nos/as professores/as uma ausência de amparo no que se refere ao trabalho com mecanismos e sistemas de imagens midiáticas, ocasionando inseguranças. Contudo, na intervenção realizada junto a um número reduzido de pedagogos/as, foi possível ressignificar alguns desses temores, apresentando outras perspectivas e proporcionando reflexões. Houve, ainda, a construção conjunta de saberes, viabilizando outros olhares quanto ao consumo crítico das manifestações midiáticas e à importância do uso consciente das tecnologias. Destaca-se particularmente a criação do Guia da Alfabetização Midiática-Visual, documento pautado no estudo e no uso da linguagem fotográfica na escola, o qual acredita-se, assim como esta pesquisa, que oportunize novas formas de se pensar e planejar os processos de ensino-aprendizagem.
MEDIATIC-VISUAL LITERACY: A HUMAN RIGHT AT SCHOOL

Published: July 2023

ABSTRACT: This study is about the relation among media culture and school territory, problematizing the role of the teacher and the school in the mediation of contents mediatically consumed by the students. The investigation debates the understandings and skills that the teachers possess in relation to the didactics turned to Mediatic-Visual Literacy inside their specific school contexts. In methodological terms, has a quantitative-qualitative approach, which central strategy is the action-research (THIOLLENT, 1986). To achieve that, are theoretically-methodologically articulated some concepts, such as: Human Rights (MARTÍN-BARBERO, 2011); Visual Literacy (KELLNER, 1995) and Media Education (BACCEGA, 2001). These notions oriented the empiric research developed with a teachers’ group from the municipal network of teaching in a town of Rio Grande do Sul/Brazil. The work comes from an investigative process of introductory poll, followed by a focal approach. Among the results of the research-action, it was verified with the teachers the absence of a support for the work with media images mechanism and systems, generating insecurities. However, in the intervention accomplished among a small number of teachers, it was possible to give another meaning to some of these fears, presenting other perspectives and offering new thoughts. There was, yet, the joint construction of knowledges, making other looks possible for the critical consumption of media manifestations and the importance of the conscious use of technologies. It’s particularly highlighted the creation of the Guide to Mediatic-Visual Literacy, a document oriented on the study and in the use of photographic language at school, believing that, as this research, will be possible to give opportunity for new ways of thinking and planning the processes of teaching-learning, also making possible to the educators and students the construction of knowledge that enable a more conscious and critic consumption of communicational artifacts, as well as more autonomy and responsibility to use the media technologies as a way of democratic fight and citizen expression.

ABSTRACT BACKGROUND: Vitamin, mineral, and metabolic deficiencies occur in the postoperative period of bariatric surgery, in the short and long term, and are worrisome intercurrences. AIMS: To evaluate the association of serum vitamin D levels with the lipid profile in obese patients undergoing bariatric surgery. METHODS: Case series of patients assisted from 2010 to 2018, in a private hospital of medium and high complexity, who underwent bariatric surgery using sleeve gastrectomy or Roux-en-Y gastric bypass techniques, monitored by the same surgeon. Sociodemographic, clinical, laboratory, and anthropometric data were collected preoperatively and at 6, 12, and 24 months after surgery. RESULTS: A total of 156 individuals, mostly female (75.6%) were monitored. The most frequent comorbidities were hepatic steatosis (76.3%) and hypertension (48.27). Regarding preoperative vitamin D levels, only 18.9% of the population had a satisfactory level (≥30 ng/mL). There was a reduction in weight and an improvement in the lipid profile after surgery. Significant correlations were observed between the lipid profile and vitamin D concentration only in the sample submitted to the Roux-en-Y gastric bypass technique: negative correlation between total cholesterol and vitamin D two years after surgery; positive correlation between triglycerides and vitamin D one year after surgery; and negative correlation between high-density lipoprotein and vitamin D two years post-surgery. CONCLUSIONS: It is essential to routinely monitor vitamin D levels and lipid profile pre- and postoperatively in order to avoid damage associated with this vitamin deficiency.

Resumen Los productos de precipitación satelital (PPS), proporcionan una fuente alternativa para aplicaciones hidrometeorológicas principalmente en áreas donde los datos de precipitación son limitados. Sin embargo, es necesario evaluar los PPS para cuantificar la incertidumbre en la estimación de la precipitación. Este estudio tuvo como objetivo evaluar el desempeño de los PPS GSMaP-G-NRT, PERSIANN-CCS, PERSIANN-CDR y PERSIANN sobre la cuenca del Lago Titicaca (CLT). Para la evaluación de los PPS se utilizaron tres métricas de desempeño que evaluaron la precisión (coeficiente de correlación, CC), error (raíz del error cuadrático medio, RMSE) y sesgo (sesgo porcentual, PBIAS). Los resultados indican que PERSIANN-CDR y PERSIANN-CCS son los productos que muestran una mayor concordancia con las mediciones de pluviómetros, pero con un gran sesgo para PERSIANN-CCS. Los hallazgos proporcionan una idea del rendimiento de PPS en la CLT que contribuye a posibles direcciones de mejora de los algoritmos para un mejor servicio en aplicaciones hidrometeorológicas.

ABSTRACT: In Brazil, the optimal dose of phosphorus in the cultivation of yerba mate (Ilex paraguariensis St. Hil.) clones has yet to be defined. This study verified the productivity of yerba mate clones in response to the application of P doses and determined the critical level of the nutrient in soil and yerba mate leaves. The experiment was developed in Itaiópolis-SC, in humic cambisol, from 2013 to 2020. Five doses of the nutrient were evaluated in two clones (BRS-BLD Aupaba and F2) of yerba mate. Fertility was defined by planting/post-planting (0, 2.3; 4.5; 6.8, and 9.0 g plant-1), canopy formation 1 (0, 10, 20, 30, 40, and 50 g plant-1), canopy formation 2 (0, 15, 30, 45, and 60 g plant-1), and production (0, 16.7; 33.3; 50.0; 66.7 kg ha-1). Harvests took place between July 2015 and January 2020, at 18-month intervals. The productivity of leaves, fine branches, and thick branches was evaluated. In the 2020 harvest, soil and leaf samples were collected to determine the critical level of P. The productivity of clone components increased with phosphate fertilization in all evaluated harvests. The critical levels of P for clones, Aupaba and F2, were 5.2 and 6.3 mg dm-3 in soil and 1.03 and 1.11 g kg-1 in leaves, respectively. Yerba mate is demanding of P, expressing maximum productivity in the planting phase, canopy formation 1 and 2, and production when doses of 5, 25, 40 g plant-1, and 35 kg ha-1 of P2O5 are applied, respectively.

ABSTRACT: The peach palm (Bactrisgasipaes) is an important alternative for heart-of-palm extraction, showing precocity, rusticity and high tillering. The seeds of this species are considered recalcitrant making storage for long periods and production of seedlings difficulty. This identified a combination of moisture content of peach palm seeds and temperature during storage for longer seed longevity. Seeds with 35% and 45% of moisture content (wet basis - wb) were storage at 20 °C and 25 ºC during 180 days. The evaluations were carried out every 60 days by the germination test, emergence in sand, shoot length, diameter of stem, shoot dry matter, root dry matter and moisture content. It was observed that seeds with moisture content of 45% wb showed better performance during storage. The storage at 20 ºC provides higher seed quality maintenance. Peach palm seeds maintain their viability for 120 days when stored with moisture content of 45% wb at 20 ºC.

ABSTRACT: The cheese after processing, generates whey, which is a residue that has potential benefit to human health. However, there are still few studies that seek to evaluate the composition and potential benefits of goat milk whey, even though it is a promising dairy source. Despite this, the large-scale generation of this waste can favor the environmental impact when improperly disposed of. Given this, the use of all content of dairy production can reverse this impact and increase the income of the dairy industry. Thus, this research prepared a powdered product based on goat’s milk whey from the spray drying technique and evaluate its physicochemical composition by chemical analytical methods and protein profile through polyacrylamide gel electrophoresis. The elaborated product had a higher carbohydrate content than protein, and the identification of protein fractions showed that the most expressive bands represented beta-lactoglobulin and alpha-lactoalbumin. Therefore, the elaborated product has the potential to generate novel products for human consumption and with potential health benefits.

ABSTRACT: Present study aimed for detection, purification, quantification of Sind Krait (Bungarus sindanus) antivenom from chicken eggs and to determine extracted antivenom efficacy in mice. Hens’ three groups were immunized by sub-lethal doses of Sind Krait venom with adjuvant paraffin oil+lecithin. Booster doses were injected subcutaneously on pectorals muscles at multiple sites after every two weeks upto eight weeks. Antibodies-IgY produced against Sind Krait venom was purified form eggs’ yolk by precipitation method with PEG-6000. Purified antivenom-IgY protein contents were quantified by Nanodrop-photometer, purity accessed by SDS-PAGE, specificity checked by Ochterloneys method and titer estimated by indirect ELISA. Antivenom efficacy was assessed in albino mice. Purified antivnom-IgY exhibited single protein band 180-190 kDa on SDS-PAGE under non-reduced condition and two-bands 63 - 65 kDa and 22 - 25 kDa correspondingly under-reduced condition. Immunodiffusion exhibited sharp precipitation lines of immune-complex (venom and extracted-IgY). In all groups (G1, G2 and G3) antivenom level sharply increase from 3rd to 4th week and maintained thereafter. G2 and G3 presented high titer upto 1:2048 dilutions, while G1 showed upto 1:1024 dilutions, as tested by indirect ELISA. In neutralization assay ED50 dose of G2 and G3 obtained antivenom was 400.23 µg/mice for more than twofold LD50 dose of venom and 100% protection was at 508.84 µg/mice that completely neutralized highly lethal dose of venom. But G1 ED50 was 405.66 µg/mice and provides 100% protection at 554.21 µg/mice. Extracted antivenom, against Sind Krait venom were highly pure, and with high neutralization capacity were produced successfully from eggs yolk first time in Pakistan.

ABSTRACT Biofloc technology (BFT) has several advantages, such as low water supply requirements and apparent feed conversion ratio (FCR), and high densities. However, there is no information on adequate densities and their effect on the large-scale production of different species. In this study, we determined the effects of the stocking density of monosex red tilapia reared using BFT on the growth performance, water quality parameters, and chemical characteristics of fish on a large scale and under culture conditions in eastern Colombia. In total, six circular tanks (diameter: 14 m, height: 1 m, and capacity: 153 m³) were used in this investigation. Two stocking densities were considered: treatment 1 (T30: 30 fish/m³) and treatment 2 (T40: 40 fish/m³), in triplicate. The water quality parameters of the two treatment densities were within the normal ranges for the species, but dissolved oxygen decreased throughout the production process. The T30 and T40 treatments did not result in significant differences in growth performance. At the end of the trial, the FCRs were 1.6 and 1.7 from T30 and T40, respectively. Fishes raised at a lower density had a similar weight gain; however, their final biomass was not significantly different. BFT did not affect the nutritional characteristics of fish; the percentage of protein (%) in tilapia was 17.81% ±1% and 16.72% ±1% in the T30 and T40 groups, respectively. None of the fish were infected by Salmonella spp. or Vibrio cholerae.

ABSTRACT Reconstructive surgery with endoprostheses is the chosen method for treating bone malignancies. Postoperative infections are frequent complications, and their treatment involves prolonged hospital stays and antibiotic therapy. Among the advancements aimed at reducing the rate of postoperative infection, the use of incisional negative pressure therapy (iNPT) has shown promising results, with no reports in the literature regarding its use in patients with such conditions. Objective: To evaluate the effectiveness of iNPT in reducing postoperative complications in surgeries for resection of bone tumors associated with modular endoprosthesis reconstruction. Methods: Retrospective case series of 16 patients diagnosed with osteosarcoma, who underwent resection and reconstruction with endoprosthesis associated with iNPT during the postoperative period. Follow-up was performed for a period of six months, and the evaluated outcomes were the incidence of postoperative infection and complications of the surgical wound. Results: The use of iNPT for a postoperative period of seven days resulted in only three (18.7%) cases of postoperative infection. No cases of wound dehiscence, seroma formation, or hematoma at the surgical site were observed. Conclusion: The rate of surgical wound complications in our case series is lower than that reported in most of the literature, and iNPT appears to be an efficient way to reduce the rate of local complications in reconstructive surgeries with endoprosthesis after resection of bone malignancies.

ABSTRACT Objective: To evaluate the early postoperative complications associated with the surgical approach of the cervical spine of patients with cervical spondylotic myelopathy (CSM), comparing the anterior surgical, the posterior surgical, and the combined approaches. Methods: This is a retrospective study based on a database with 169 patients. Demographic data, such as gender and age, and surgical data, such as surgical approach, number of segments with arthrodesis, surgical time, and complications, were evaluated. Complications were divided into major (deep surgical wound infection, intercurrence with the implant, early new compression, and heart failure) and minor (dysphagia, superficial infection, pain, urinary intercurrence, neuropraxia of the C5 root, acute confusional state, and surgical wound hematoma). Results: This included 169 patients, 57 women (33.7%) and 112 men (66.2%). Age ranged from 21 to 87 years, with a mean of 56.48 (± 11) years. Of these, 52 (30.8%) underwent the anterior approach; 111 (65.7%), the posterior approach; and 6 (3.5%), the combined approach. Conclusion: As in the literature, we evinced dysphagia, pain, and superficial infection of the surgical wound as the most frequent postoperative complications. However, it was impossible to establish a statistical relationship between the incidence of complications and surgical time, access route, and number of fixed segments.

ABSTRACT Currently, the market offers a wide variety of suture threads, made of materials with different structural and chemical properties. Among many other characteristics, they vary in origin, absorption or degradation, and structure. From this variety, the clinical doubt arises as to which material provides the patient with the best healing quality. Objective: This study aims to comparatively evaluate two different types of suture threads-Monocryl® (polyglycaprone 25) and Ethilon® (nylon)-regarding their ability to aid in tissue regeneration by a histological and immunohistochemical analysis of the skin of rats sutured with the aforementioned materials. Methods: This basic experimental study used 12 adult Wistar rats, randomly divided into three groups with four animals each and subjected to four longitudinal incisions under anesthesia. Each group corresponded to a postsurgical evaluation date (one, seven, and 14 days). Results: At 14 postoperative days, the studied groups had no histological difference. However, the use of nylon thread showed greater evidence of earlier fibrotic union. Conclusion: This study found no histological difference in healing 14 days after surgery among the techniques and the types of suture threads. Level of Evidence II, Therapeutic Studies.

ABSTRACT Simultaneous rupture of the patellar and contralateral quadriceps tendons in patients with chronic renal failure is an extremely rare condition, with few cases described in the medical literature. Several systemic pathological conditions that lead to a decline in kidney function can predispose individuals to spontaneous tendon rupture, such as rheumatological and endocrine diseases, and even gestational conditions, such as eclampsia. Objective: In this case report, we describe the case of a 39-year-old woman with chronic renal failure on dialysis due to a previous history of eclampsia that caused the simultaneous rupture of the patellar and contralateral quadriceps tendons. Methods: Data were collected by interviews, direct observation, and medical examinations, and include information about the case history, the patient’s characteristics, the former interventions, and the results obtained. Results: The surgery to repair the patellar and contralateral quadriceps tendons was performed by transosseous tunnels and the Krackow technique with nonabsorbable sutures was used. The semitendinosus tendon was removed and used as reinforcement. Conclusion: Patient under follow-up with good functional results in both knees. Level of Evidence V, Expert Opinion.

ABSTRACT Objective: To assess the impact of the COVID-19 pandemic on the epidemiology and clinical outcomes of open fractures considering the periods before and during the pandemic. Methods: An observational and retrospective study, which included patients aged over 18 years, admitted to the Orthopedics and Traumatology Ward of Hospital São Paulo, of the Federal University of São Paulo (UNIFESP). Data was collected in two moments: pre-pandemic (March 1, 2019, to February 29, 2020) and during the pandemic (March 1, 2020, to February 28, 2021). Results: In total, 183 patients were evaluated with a mean age of 36 years ± 14 years. In the pre-pandemic period, 94 patients underwent surgery, 81 men (85.37%) and 13 women (14.2%), with a mean age of 36 ± 3 years. During the pandemic period, 89 patients were subjected to surgery, 77 men (86.6%) and 12 women (13.4%), with a mean age of 38 ± 3 years. Conclusion: During the pandemic, open fractures were still more common in men. Regarding hospital indicators, the prevalence of infections in the surgical wound and the length of stay of patients with open fractures increased, however, with little significance. Fractures classified as Gustilo IIIA were the most common, while the most common according to the AO classification were 33, 34, 42, 43, 2R3, and 2R3 + 2U2. The frequency of run overs during the pandemic decreased. However, firearm projectile injuries and falls and occupational injuries increased. Level of Evidence III, Retrospective Comparative Study.
