The obese group presented higher BP and HR values at rest and autonomic impairment, characterized by a reduction in parasympathetic activity and relative predominance of sympathetic activity.
PLB led to a loss of fractal correlation properties of heart rate in the direction of linearity in patients with COPD as well as an increase in vagal activity and impact on the spectral analysis. The difference in the magnitude of the changes produced by PLB between groups may be related to the presence of the disease and alterations in the respiration rate.
HighlightsThe most commom complications of Meckel’s diverticulum are inflammation, haemorrhage, and intestinal obstruction.The perforation of a Meckel’s diverticulum by a foreign body is a very rare complication, with few cases reported in the literature.Definitive treatment is surgical intervention, and should not be delayed by supplementary radiographic imaging in patients with peritonitis.
The administration of yeast-derived immunostimulants leads to improvement of the immune system and growth performance preventing the antibiotics misuses. The objective of this study was to evaluate the effects of dietary Actigen Ò [0, 0.04, 0.06 and 0.08 % of Actigen (ACT)], on the immunological and physiological responses and growth performance of tilapia after lipopolysaccharide (LPS) inoculation. The experiment was conducted in two trials. In the first trial, the ACT was offered for 30 and 60 days; in the second trial, the ACT was offered for 60 days, and then fish were challenged by intraperitoneal injection with LPS and sampled at 5 and 12 days after inoculation. After the first trial, immunological, hematological and biochemical parameters, intestinal morphology and the growth performance were assessed, whereas in the second trial, immunological, hematological and biochemical parameters were assessed. Supplementation of diets with ACT showed a significant effect mainly after 60 days of feeding, with increased lysozyme, globulin, HTC, MCV, erythroblasts, leukocytes, lymphocytes and monocytes. A general decrease in cells and globulin occurred at 5 days after the LPS challenge, with partial recovery at 12 days after the challenge. In addition, the study demonstrated that the use of ACT, an extract derived from yeast cell walls and containing
Introdução: nos últimos anos, diversos estudos analisaram o comportamento do sistema nervosoautônomo (SNA) frente à obesidade e utilizaram, para esta análise, a variabilidade da frequênciacardíaca (VFC). Embora descrito na literatura que adultos obesos apresentam disfunções do SNA, faltam informações referentes a crianças obesas e os achados existentes ainda são inconclusivos. Objetivo: reunir estudos que abordem a análise do SNA, por meio da VFC, em crianças obesas para melhor compreender a influência da obesidade sobre esse sistema nessa população e fornecer uma atualização dos achados publicados nos últimos onze anos referentes ao tema. Método: a busca dos artigos foi realizada nas bases de dados Pubmed, Ibecs, Medline, Scielo, Cochrane e Lilacs por meio dos seguintes descritores da área da saúde (DeCS): frequência cardíaca, sistema nervoso autônomo, obesidade, criança e sistema nervoso simpático e suas respectivas versões na língua inglesa (MeSH). Resultados: a busca resultou em 11 artigos, os quais demonstraram que, em geral, crianças obesas apresentam menor atividade do SNA parassimpático e os resultados são inconclusivos para a atividade simpática. Além disso, intervenções como dieta e atividade física podem melhorar a condição de atuação do SNA nessas crianças. Conclusão: crianças obesas apresentam modificações na atuação do SNA, o que demonstra a necessidade de atenção precoce a esta população para evitar complicações futuras.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
