Prediction and Evaluation of Breast Myopathy

Broiler breast myopathies, including woody breast, white striping, and spaghetti breast, negatively impact the industry. Therefore, evaluation, prediction, and frequency of these muscle abnormalities on modern birds are important for decision making. Modern broilers are not highly active and often sit with the breast of the bird resting on the floor. Therefore, the first experiment was to promote bird movement and explore the impact on the breast myopathies. The movement was stimulated by human interaction (walking through pen) and higher light intensity so that birds walked around the pen more often throughout the day. The control group had normal low light intensity and minimal human interaction. However, the results were not different between the treatments on performance or breast myopathies. In other studies, broilers were palpated for woody breast (WB) and the breast region and/or fillets were measured for width, length, thickness, etc. in efforts to develop prediction of WB during growout and in the plant. Differences on the thickness and other part of the measurements on the fillets were found between WB categories (normal to severe) and it was determined that these features were good predictors for the differentiation on the severe WB and normal categories. Furthermore, palpation and measurements of the breast on the live bird throughout the growing period were also well correlated and some measurements were good predictors, like measurements on the cranial region of the breast with a cloth tape. There was observed that the different strains were different between each other as well the WB myopathy. Furthermore, the broiler breast myopathies demographic chapter to summarize all the data collected in 3 years with the most utilized strains in the market. Generally, myopathies increase as the birds get older and larger and they also increase AS breast yield increases to higher levels (breast yield \u3e 30%). Additionally, males generally had greater WB than females and females had greater SM than males

Anterior ocular segment study with the Scheimpflug rotational camera in refractive surgery candidates

PURPOSE: To analyze the anterior segment of refractive surgery candidates and establish the variability pattern in this population regarding corneal volume, anterior chamber volume and depth and corneal thickness, using the noncontact three dimensional analyzer Pentacam®. METHODS: A retrospective study of 297 eyes of 149 patients was conducted using Pentacam®. According to the spherical equivalent value two groups were created, myopia (n=242 eyes) and hyperopia (n=55 eyes), to analyze the variables of corneal volume, anterior chamber volume and depth and corneal thickness. RESULTS: The mean values of the myopia group were: corneal total volume 59.37 ± 3.51mm³, corneal volume at 3 mm 3.87 ± 0.23 mm³, at 5 mm 11.31 ± 0.67 mm³, and at 7 mm 24.30 ± 1.43 mm³, anterior chamber volume 198.74 ± 32.40 mm³, anterior chamber depth 3.19 ± 0.28 mm and corneal thickness 533.33 ± 33.47 mm. In the hyperopia group, the mean total corneal volume was 60.77 ± 3.31 mm³, corneal volume at 3 mm from the apex was 4.01 ± 0.20 mm³, at 5 mm was 11.73 ± 0.58 mm³, and at 7 mm was 25.09 ± 1.21 mm³, the anterior chamber volume was 146.61 ± 32.86 mm³, the anterior chamber depth was 2.76 ± 0.38 mm and the corneal thickness was 550.52 ± 29.49 mm. The difference between the groups was significant for all variables (p<0.05). CONCLUSION: We observed in this study that patients with myopia had lesser mean corneal volume and pachymetry, and greater anterior chamber depth and volume compared with hyperopic patients.OBJETIVO: Analisar o segmento anterior com aparelho de câmera rotatória de Scheimpflug (Pentacam®) em candidatos à cirurgia refrativa, estabelecendo o padrão de variabilidade do volume corneano, do volume e da profundidade da câmara anterior e da paquimetria óptica nesta população.

Interesses de atores sociais na regulamentação da telemedicina no Brasil (2018-2020)

Introdução: A regulamentação da telemedicina no Brasil tem sido objeto de debate público nos últimos anos e a pandemia de COVID-19 provocou acelerações nesse processo. Objetivo: Este estudo tem como objetivo identificar os interesses de atores sociais no contexto da regulamentação da telemedicina no Brasil, tendo como marcadores a Resolução CFM nº 2.227/2018 e posterior revogação e a autorização enquanto durar a Emergência em Saúde Pública de Importância Nacional relativa à COVID-19, a partir dos conceitos da Teoria da Produção Social de Matus (1996a, 1996b e 2005), que versam sobre o processo de produção social e possibilitam a análise de políticas públicas com base no que é realizado pelos atores sociais. Segundo o autor, a figura do ator social age movida pela convergência entre interesse e valor e a ação de cada ator se refere às suas capacidades, sendo que o interesse (intenção) pode ser observado a partir das posições de apoio, rejeição e indiferença. Metodologia: A metodologia utilizada foi qualitativa, com a realização de pesquisa exploratória e bibliográfica, e os métodos foram o levantamento de instrumentos normativos e documentos de acesso público, bem como notícias em portais da imprensa e institucionais dos atores envolvidos a partir de 2018. Resultados: Observou-se que o conceito de telemedicina teve notória complexificação e que, em geral, os sindicatos, conselhos regionais e associações de classe tiveram, inicialmente, posição de rejeição firme e, posteriormente, de apoio duvidoso; o Ministério da Saúde, por sua vez, passou da posição de indiferença tática para indiferença oportunista; a imprensa teve, no primeiro momento, posição de indiferença oportunista e, no segundo, de apoio aparente; a Frente Parlamentar Mista da Telessaúde, por fim, manifestou posição de apoio firme a partir de sua criação. Conclusão: As acumulações sobre a regulamentação da telemedicina desde 2018 modificaram o cenário, sendo que a pandemia de COVID-19 fez com que o interesse e o valor dado à temática tenha crescido exponencialmente entre todos os atores sociais envolvidos.Introduction: The regulation of telemedicine in Brazil has been the subject of public debate in recent years and the COVID-19 pandemic has caused accelerations in this process. Objective: This study aims to identify the interest of social actors in the context of telemedicine regulation in Brazil, with the Resolution CFM No. 2.227/2018 and subsequent revocation and the authorization as long as the Public Health Emergency of National Importance related to COVID-19 lasts as markers, based on the concepts of Matus’s Theory of Social Production (1996a, 1996b and 2005), which deal with the process of social production and enable the analysis of public policies based on what is done by social actors. According to the author, the figure of the social age actor, moved by the convergence between interest and value, and the action of each actor refers to their resources, and the interest (intention) can be observed from the positions of support, rejection and indifference. Methodology: The methodology used was qualitative, with exploratory and bibliographic research, and the methods were the survey of normative instruments and publicly accessible documents, as well as news in press and institutional portals of the actors involved from 2018. Results: It was observed that the concept of telemedicine had a notorious complexification and, in general, that unions, regional councils and class associations had, initially, a position of firm rejection and, later, of doubtful support; the Ministry of Health, in turn, moved from the position of tactical indifference to opportunistic indifference; the press had, at first, a position of opportunistic indifference and, at the second, of apparent support; the Mixed Parliamentary Front on Telehealth, finally, expressed a position of firm support since its creation. Conclusion: It is concluded that the accumulations on the regulation of telemedicine since 2018 have changed the scenario, and the COVID-19 pandemic has caused the interest and value given to the topic to have grown exponentially among all social actors involved

A participação de uma aluna com necessidades educacionais especiais em atividades colaborativas em grupo

A educação inclusiva busca permitir que todos os estudantes tenham suas necessidades atendidas e possam participar efetivamente da construção do cenário escolar. Este estudo microetnográfico investiga como uma turma de 7º ano de uma escola municipal de Ensino Fundamental da rede pública de Porto Alegre inclui uma aluna com necessidades educacionais especiais nas atividades colaborativas em grupo. Como extensão do projeto de pesquisa de Stein (2015), que buscou observar como se dá a construção do conhecimento em atividades pedagógicas colaborativas realizadas em grupo em uma sala de aula de sétimo ano, dá-se continuidade a esse olhar para as atividades em grupo. O foco específico, no entanto, é a inclusão de uma aluna com necessidades educacionais especiais, de modo a mostrar como ela participa dessas atividades, tendo em vista que a escola tem como princípios norteadores da prática que “O trabalho em grupo qualifica a aprendizagem”, “Todos podem aprender” e “Diferença não é deficiência” (PERSCH et al., 2006). Para tanto, procedeu-se à visualização de mais de 12 horas, das 90 horas geradas por Stein (2015), dos registros audiovisuais e segmentação de ocorrências, que a seguir foram transcritas e submetidas a análise sequencial e multimodal à luz da perspectiva teórico-metodológica da Microetnografia (GARCEZ, 2017) e da Análise da Conversa Etnometodológica (LODER; JUNG, 2008). Apresentam-se aqui dois segmentos selecionados que ilustram essa participação: o primeiro é representativo de um conjunto de sete ocorrências e apresenta uma interação inclusiva; o segundo segmento é a única ocorrência de interação excludente. Nesse sentido, esta análise mostra como as políticas de inclusão se concretizam dentro da sala de aula de uma escola pública e como essa escola concretiza seu Projeto Político-Pedagógico na prática.Inclusive education seeks to enable all students to have their needs met and to participate effectively in the construction of their own schooling. This microethnographic study investigates how a Grade 7 class at an elementary school within the municipal public school system of Porto Alegre manages to include a special educational needs student in their collaborative groupwork activities. Extending Stein's (2015) research which examined the construction of knowledge in collaborative groupwork activities in this Grade 7 classroom, we sought to observe the inclusion of special educational needs students, since the school ‘s guiding pedagogical principles state that "Group work qualifies learning", "Everyone can learn" and "Difference is no handicap" (PERSCH et al., 2006). Of the 90 hours of audiovisual records of classroom interaction generated by Stein (2015), 12 hours were examined in detail for this study, and eight interactional segments were identified in which the focal student’s participation was particularly foregrounded. These segments were then transcribed and submitted to sequential and multimodal analyses inspired by microethnographic (GARCEZ, 2017) and conversation analytic (LODER and JUNG, 2008) theoretical-methodological perspectives. Two selected segments are analyzed and discussed to illustrate such participation: the first is representative of a set of seven occurrences resulting in the student’s inclusion to complete the pedagogical activity; the second segment is the only occurrence in which she was excluded from full participation. The analyses thus show how policies of inclusion do take place within this public school classroom and how this school makes good on its Political-Pedagogical Project

Hamiltonian systems: symbolical, numerical and graphical study

Effect of different methods of fiber post cleaning on post resistance to dislodgement from the root canal

Aim: To evaluate the effect of different methods of fiber post cleaning on post resistance to dislodgement after cementation. Methodology: Sixty bovine incisors were divided into six groups according to the cleaning method applied to the fiber posts. GC: no cleaning; GES: autoclave sterilization; GHP: 2.5% sodium hypochlorite; GCL: 2% chlorhexidine digluconate; GAL: 70% alcohol; GAF: 35% phosphoric acid. The posts were cemented in the canals using a self-adhesive resin cement. The specimens were sectioned perpendicularly along the long axis of the root with an av-erage thickness of 1.61 mm at the cervical, middle, and apical root thirds and subjected to the push-out test. After the test, they were examined under a stereomicroscope to de-termine failure mode. Data were analyzed using one-way ANOVA and the Tukey test (α=0.05). Results: The comparisons with the GC group revealed statistical differences only in the middle and apical thirds of the GCL group and in the apical third of the GHP group. Only the apical thirds were different from the middle and cervical thirds in the GC group, and the cervical thirds, from the middle and apical thirds of the GES group. Conclusions: The resistance to dislodgement of fiber posts cemented in root canals was not affected by the different cleaning methods under study
