RESUMO
RESUMO Objetivo: O objetivo deste estudo foi analisar o comportamento alimentar de crianças e adolescentes com transtorno do espectro autista. Métodos: Participaram deste estudo 21 crianças e adolescentes com TEA, na faixa etária de 2 a 14 anos de idade, de ambos os sexos. Foi aplicado um questionário sobre o comportamento alimentar com os 21 pais e/ou responsáveis das crianças. Esse instrumento é composto por 53 questões, distribuídas nas seguintes categorias: Motricidade na mastigação; Seletividade alimentar; Aspectos comportamentais; Sintomas gastrointestinais; Sensibilidade sensorial e Habilidades nas refeições. Resultados: A análise dos dados obtidos revela que as crianças com TEA apresentaram maiores alterações no comportamento alimentar nas categorias Seletividade alimentar (34,4%), Aspectos comportamentais (27,1%) e Motricidade na mastigação (21,9%). E houve correlação entre a categoria Motricidade na mastigação com todas as outras categorias. Houve também correlação entre seletividade alimentar com aspectos comportamentais e aspectos comportamentais com sensibilidade sensorial e habilidades nas refeições. Conclusão: Portanto, é possível observar que, no comportamento alimentar de crianças e adolescentes com TEA, há uma tendência a seletividade alimentar, comportamentos habituais durante as refeições e dificuldades motoras no que se refere à mastigação e à ingestão dos alimentos.
ABSTRACT Objective: The objective of this study was to analyze feeding behavior in children with autism spectrum disorder. Methods: Twenty-one children with autism spectrum disorder (ASD) participated in this study, aged 2 to 14 years old, of both sexes. A questionnaire on feeding behavior was applied to the 21 parents and/or responsible of the children. This instrument consists of 53 questions, distributed in the following categories: Motricity in chewing; Food selectivity; Behavioral aspects; Gastrointestinal symptoms; Sensory sensitivity and Skills in meals. Results: The analysis of the data obtained reveals that children with ASD showed greater changes in eating behavior in the categories Food selectivity (34.4%), Behavioral aspects (27.1%) and Motricity in mastication (21.9%). And there was a correlation between the chewing motricity category with all other categories. There was also a correlation between food selectivity with behavioral aspects and behavioral aspects with sensory sensitivity and mealtime skills. Conclusion: Therefore, it is possible to observe that in the eating behavior of children with autism spectrum disorder there is a tendency towards food selectivity, habitual behaviors during meals and motor difficulties with regard to chewing and food intake.
RESUMO
Abstract Background: The association of scaffolds to repair extensive bone defects can contribute to their evolution and morphophysiological recomposition. The incorporation of particulate biomaterials into three-dimensional fibrin bioproducts together with photobiomodulation therapy (PBM) has potential and can improve regenerative medicine procedures. The objective of this experiment was to evaluate the effects of PBM therapy on critical size defects filled with xenogenic bone substitute associated with fibrin biopolymer. Methods: A critical defect of 8 mm was performed in 36 Wistar male adult rats that were divided into four groups. Groups BC and BC-PBM were defined as controls with defects filled by a clot (without or with PBM, respectively) and groups XS and XS-PBM that comprised those filled with biocomplex Bio-OssTM in association with fibrin biopolymer. PBM was applied immediately after the surgery and three times a week every other day, with the parameters: wavelength of 830 nm, energy density 6.2 J/cm2, output power 30 mW, beam area of 0.116 cm2, irradiance 0.258,62 W/cm2, energy/point 0.72 J, total energy 2.88 J. Fourteen and 42 days after the surgery, animals were euthanatized and subjected to microtomography, qualitative and quantitative histological analysis. Results: The BC-PBM and XS-PBM groups had a similar evolution in the tissue repair process, with a higher density of the volume of new formed bone in relation to the groups without PBM (p = 0.04086; p = 0.07093, respectively). Intense vascular proliferation and bone deposition around the biomaterial particles were observed in the animals of the groups in which biocomplex was applied (XS and XS-PBM). Conclusion: PBM therapy allowed an improvement in the formation of new bone, with a more organized deposition of collagen fibers in the defect area. Biocomplex favored the insertion and permanence of the particulate material in bone defects, creating a favorable microenvironment for accelerate repair process.

The vertebral heart size is a method used to measure the cardiac dimension in order to identify the remodeling of the chambres in heart disease. This study aims to determinate the vertebral heart size values at right lateral and ventrodorsal radiographs views relating to canines weight and body area variations. For the purpose of the study 40 healthy dogs within the age of 1 to 6 years, males and females, with deep or intermediated thorax were selected, brachycephalic dogs were not included in the study; the dogs were separated in four groups: group 1(n=9) compound of dogs up to 5 kg; group 2 (n=8) with dogs from 5,1 to 10 kg; group 3 (n=12) with dogs from 10,1 to19 kg and group 4 (n=11) with dogs weighing more than 19,1 kg. The values of body score, body mass index and the thorax configuration where previously measured, as well as the vertebral heart size and the depth width ratio from the radiographs. The results demonstrated intervals of right lateral-lateral vertebral heart size 9.9 to 10.4v and ventro-dorsal vertebral heart size of 9.8-10.3v. The study results show that the vertebral heart size numbers did not correlate with weight or body area, regardless the type of radiography view. Therefore, it can be concluded that the vertebral heart size in right lateral and ventrodorsal radiography can be used to rate the cardiac area, not suffering influence by the dog's weight or body area.
O vertebral heart size é um método utilizado para mensurar a dimensão cardíaca visando identificar os remodelamentos das câmaras nas cardiopatias. O objetivo do estudo foi determinar os valores de vertebral heart size nas projeções radiográficas latero-lateral direita e ventro-dorsal conforme as variações do peso e área corporal. Para isso, foram selecionados 40 cães hígidos com idade entre 1 e 6 anos, machos e fêmeas, com padrão torácico intermediário e profundo, com exclusão dos braquicefálicos; os cães foram divididos em quatro grupos: grupo 1 (n=9) composto por cães de até 5 kg; grupo 2 (n=8) com cães de 5,1 a 10 kg; grupo 3 (n=12) com cães de 10,1 a 19 kg e grupo 4 (n=11) com cães acima de 19,1 kg. Os valores de escore corporal, índice de massa corporal e conformação torácica foram previamente mensurados, bem como os valores dos vertebral heart size a relação profundidade/largura torácica das radiografias. Os resultados demonstraram intervalos de vertebral heart size latero-lateral 9.9 a 10.4v e vertebral heart size ventro dorsal de 9.8-10.3v. Os valores não apresentaram correlação com o peso e área corporal nos grupos estudados, independente das projeções estudas. Assim, pode-se concluir que método vertebral heart size nas projeções estudadas é aplicável na avaliação da área cardíaca, não sofrendo influências do peso e área corporal canina.
