Owing to the lack of research on human amniotic membrane at different gestational stages, the canine model is considered ideal because of its genetic and physiological similarities. We aimed to characterize the canine amniotic membrane (CAM) cell lineage in different gestational stages and evaluate the expression of immunomodulatory genes.Materials and Methods: Twenty CAMs from early (20– 30 days) (n=7), mid- (31– 45 days) (n=7), and late gestation (46– 63 days) (n=6) stages were studied. The cell features were assessed by cell viability tests, growth curve, colony-forming units, in vitro differentiation, cell labeling for different immunophenotypes, and pluripotent potential markers. The cells were subjected to RT-PCR and qPCR analysis to determine the expression of IDO, HGF, EGF, PGE2, and IL-10 genes.Results: CAM cells exhibited a fibroblastoid morphology and adherence to plastic with an average cell viability of 78.5%. The growth curve indicated a growth peak in the second passage and we obtained an average of 138.2 colonies. Osteogenic, chondrogenic, and adipogenic lineages were confirmed by in vitro differentiation assays. Cellular immunophenotyping experiments confirmed the presence of positive mesenchymal markers (CD90 and CD105) and the low or negative expression of hematopoietic markers (CD45 and CD34). Qualitative analysis of the immunomodulatory functions indicated the expression of the IDO, HGF, EGF5, and PGE2 genes. When stimulated by interferon-gamma, CAM cells exhibited higher IDO levels throughout gestation.Conclusion: The CAMs from different gestational stages presented features consistent with mesenchymal stem cell lineage; better results were observed during the late gestation stage. Therefore, the gestational stage is a key factor that may influence the functionality of therapies when using fetal membrane tissues from different periods of pregnancy.Keywords: canine stem cells, immunomodulation, fetal annexes

Resumo Este artigo investiga aspectos legais e soluções éticas envolvidas no comércio ilegal de órgãos, atividade que provoca debates sobre ética e moral. Trata-se de revisão integrativa da literatura realizada por meio de busca nos portais Biblioteca Virtual em Saúde, PubMed e SciELO. Foram analisados 14 artigos, que apontaram baixa oferta associada a alta demanda por órgãos como etiologia principal do problema. Constatou-se que esse mercado se aproveita de populações vulneráveis para coagi-las a doar órgãos, e, além disso, a falta de conexão entre bancos de dados internacionais e instabilidades nos países com altas taxas de tráfico dificultam a ação policial no enfrentamento desse crime. O combate ao tráfico de órgãos deve ter como base o incentivo à doação legal de órgãos, o enfrentamento do “turismo de transplante” e ações direcionadas a países mais vulneráveis. Entidades internacionais têm papel fundamental para que haja trabalho conjunto em diferentes nações na repressão desse tipo de crime.

Este artigo tem como objetivo apresentar um breve histórico sobre a educação brasileira e mostrar a opinião de alguns professores de matemática sobre a importância da história da educação brasileira para o fazer docente. O estudo é de natureza qualitativa, se caracterizando como um estudo de caso, baseado na análise de entrevistas com quatro professores de matemática, entre efetivos e temporários, que responderam a respeito da importância da história da educação brasileira. A respeito das entrevistas, as respostas evidenciam a complexidade existente entre a história da educação e a prática docente. De modo geral, conclui-se que o estudo sobre a educação brasileira é fundamental para os docentes, principalmente os de matemática. Apesar dos avanços na educação, ainda há muito a ser melhorado, como por exemplo, o desenvolvimento de uma prática mais consciente e contextualizada. O trabalho aponta que são de extrema relevância investimentos nesta área, tanto para pesquisas, quanto para a melhor atuação docente.

The COVID-19 pandemic is already considered one of the biggest global health crises. In Rio Grande do Norte, a Brazilian state, the RegulaRN platform was the health information system used to regulate beds for patients with COVID-19. This article explored machine learning and deep learning techniques with RegulaRN data in order to identify the best models and parameters to predict the outcome of a hospitalized patient. A total of 25,366 bed regulations for COVID-19 patients were analyzed. The data analyzed comes from the RegulaRN Platform database from April 2020 to August 2022. From these data, the nine most pertinent characteristics were selected from the twenty available, and blank or inconclusive data were excluded. This was followed by the following steps: data pre-processing, database balancing, training, and test. The results showed better performance in terms of accuracy (84.01%), precision (79.57%), and F1-score (81.00%) for the Multilayer Perceptron model with Stochastic Gradient Descent optimizer. The best results for recall (84.67%), specificity (84.67%), and ROC-AUC (91.6%) were achieved by Root Mean Squared Propagation. This study compared different computational methods of machine and deep learning whose objective was to classify bed regulation data for patients with COVID-19 from the RegulaRN Platform. The results have made it possible to identify the best model to help health professionals during the process of regulating beds for patients with COVID-19. The scientific findings of this article demonstrate that the computational methods used applied through a digital health solution, can assist in the decision-making of medical regulators and government institutions in situations of public health crisis.

Nesse sentido, este relato de experiência analisa as reflexões construídas a partir da oficina “Leitura no colo”, construída de acordo com as demandas voltadas para a área da Educação, a qual teve como objetivo fomentar a prática de leitura dentro das escolas com os responsáveis dos alunos. Essa experiência promoveu a reflexão sobre o papel social da leitura e de que forma ela contribui com a formação inicial das crianças, ao mesmo tempo em que possibilitou às trilheiras e aos trilheiros compreenderem a extensão universitária de forma não-assistencialista, interprofissional e interdisciplinar, de significativa importância para uma formação cidadã.

A study was conducted to evaluate the effect of an emulsifier on reduced-energy diets using two fat sources for broilers. The study was designed as a 2 x 3 factorial arrangement of treatments. The first factor was 2 fat sources (poultry fat or beef tallow). The second factor was a basal diet with the recommended energy levels, a diet with a 0.83 MJ/kg of energy reduction, and a diet with an energy reduction and inclusion of 1 g emulsifier/kg of diet. The emulsifier used in this study was composed of soy lecithin and polyethylene glycol ricinoleate. The emulsifier increased apparent metabolizable energy (AME) and apparent metabolizable energy corrected for nitrogen balance (AMEn) in beef tallow diets compared to energy-reduced diets (P

Resumo Este trabalho objetivou avaliar a bioacessibilidade in vitro de α-caroteno, β-caroteno, licopeno e de compostos fenólicos, e a capacidade antioxidante em farinhas de amêndoa, polpa e casca do fruto pequi. Além disso, inter-relacionar estes resultados com a atividade de água, acidez e parâmetros de cor, por meio da análise de componentes principais. Os frutos foram coletados no estado de Mato Grosso, sendo higienizados, descascados, despolpados e retiradas as amêndoas. A quantificação das concentrações totais e bioacessíveis dos carotenoides e compostos fenólicos e a capacidade antioxidante foram feitas por espectrofotometria UV-Visível. Os ensaios de bioacessibilidade in vitro foram feitos por meio de três etapas: digestão salivar, gástrica e intestinal. As maiores concentrações de α-caroteno (63,81 µg/g), β-caroteno (59,83 µg/g) e licopeno (40,66 µg/g) foram obtidas para farinha da polpa do pequi. Porém, as maiores porcentagens de bioacessibilidade de α-caroteno (59,69%), β-caroteno (96,14%) e licopeno (44,13%) foram encontradas na farinha da amêndoa. Os teores de compostos fenólicos totais foram: 210,50, 402,21 e 9475,69 mg GAE/100g, para as farinhas de amêndoa, polpa e casca, respectivamente, sendo a maior porcentagem de bioacessibilidade (86,68%) encontrada na farinha da polpa. A farinha da casca do pequi apresentou maior capacidade antioxidante (EC50) 45,71 g/g de DPPH. Os maiores resultados de L* (42,19), a* (4,17), b* (8,39) e acidez titulável (17,83 mL NaOH/100 g) foram verificados na farinha da polpa e o menor pH (3,34), na farinha da casca. A análise de componentes principais indicou que o pH e a acidez titulável podem influenciar na bioacessibilidade de compostos fenólicos e carotenoides, e na capacidade antioxidante. Os resultados sugerem que as farinhas do pequi apresentam compostos bioativos bioacessíveis e boa capacidade antioxidante, e podem ser uma alternativa tecnológica no enriquecimento de produtos alimentícios.

Busca-se refletir sobre a contribuição do conhecimento produzido em História da Educação para pensar o momento atual de desmonte da educação no país, em particular, a educação pública. Nesse sentido, discute-se o papel da educação como um campo de disputa entre várias propostas de sociedade, entre diferentes concepções do mundo, como um terreno onde os grupos sociais lutam pela hegemonia, pela conquista do consenso para seus diferentes projetos societários.

Objective: to assess the analgesic efficacy of subcutaneous lidocaine and multimodal analgesia for chest tube removal following heart surgery. Methods: sixty volunteers were randomly allocated in two groups; 30 participants in the experimental group were given 1% subcutaneous lidocaine, and 30 controls were given a multimodal analgesia regime comprising systemic anti-inflammatory agents and opioids. The intensity and quality of pain and trait and state anxiety were assessed. The association between independent variables and final outcome was assessed by means of the Chi-squared test with Yates' correction and Fisher's exact test. Results: the groups did not exhibit significant difference with respect to the intensity of pain upon chest tube removal (p= 0.47). The most frequent descriptors of pain reported by the participants were pressing, sharp, pricking, burning and unbearable. Conclusion: the present study suggests that the analgesic effect of the subcutaneous administration of 1% lidocaine combined with multimodal analgesia is most efficacious.

The use of insecticides known as insect growth regulators, which are considered more selective to natural enemies, may be an alternative to integrated pest management of stink bugs of the main crops in Brazil. The objective of this study was to evaluate histological changes in the reproductive system of Dichelops melacanthus as well as female fecundity and egg fertility after use of growth-regulating insecticides. The insecticides used were buprofezin (a chitin biosynthesis inhibitor) at a sublethal concentration (LC30 of 2.99 g L-1) and pyriproxyfen (a juvenile hormone analog) at a sublethal concentration (LC30 of 8.35 mL L-1). A completely randomized experimental design was used, with 10 repetitions and 10 insects per experimental unit. Two bioassays were performed: in the first bioassay, fecundity (eggs/female) and fertility (nymph eclosion) of the insects that survived the insecticides were evaluated; in the second bioassay, morphological alterations of the ovarioles of adult females and of the testes of adult male insects that survived the insecticides were evaluated. Buprofezin and pyriproxyfen did not affect the adult sex ratio or female fecundity. Pyriproxyfen reduced the percentage of ecloded nymphs (71.6%) compared with that of the control and buprofezin (96.4 and 90.6%, respectively) treatments and had an ovicidal effect, with direct and indirect action on embryogenesis. Morphological changes were observed in both treatments with buprofezin and pyriproxyfen. The alterations observed in female and male reproductive systems may occur by the action of buprofezin and pyriproxyfen on the morphology of both ovarioles and testes.

Background: The validity of a nursing diagnosis depends on a continuous investigation process in different populations to provide clinical evidence. The risk for corneal injury nursing diagnosis was approved in 2013 and only reviewed in 2017, demonstrating the need to perform a clinical validation to improve it. Aim: To perform a causal validation of the risk for corneal injury nursing diagnosis in critically ill adults. Study design: A prospective cohort study was performed in two intensive critical care units in Northern Brazil with adults aged over 18 years without corneal injury at admission. The patients were evaluated for 10 days, using a data collection tool composed of risk factors for the risk for corneal injury nursing diagnosis. The independent variables were described through absolute and relative frequency. The accuracy measures and risk factors were identified through Cox regression, considering a 95% confidence interval. Results: The nurses assessed 209 critically ill adults and identified that 76.0% of them presented the risk for corneal injury nursing diagnosis, with 16.3% developing a corneal injury, all having previously presented the risk for corneal injury nursing diagnosis. The risk factors identified were eyeball exposure (hazard ratio: 1.78; 95% CI: 1.27–2.51), Glasgow score < 6 (hazard ratio: 1.73; 95% CI: 1.15–2.60) and periorbital oedema (hazard ratio: 1.43; 95% CI: 1.03–1.99), with these factors showing high specificity, and the mechanical ventilation variable, showing high sensitivity, with ROC curve of.86. Conclusion: Eyeball exposure, Glasgow score < 6 and periorbital oedema are the risk factors of the risk for corneal injury nursing diagnosis, in critically ill adults. These risk factors guide nursing interventions. This causal validation can improve the risk for corneal injury nursing diagnosis levels of evidence in the NANDA International Taxonomy. Relevance to clinical practice: It is necessary to guide nursing interventions for critically ill adults with lowered level of consciousness and corneal exposure for the prevention of corneal injury.
