Autogenous tooth transplantation : evaluation of pulp tissue regeneration

Objective: The aim of this study was to assess the pulp survival that occur in transplants of autologous teeth, by comparing two surgical techniques: the conventional technique (autotransplantation for newly formed alveoli), and an alternative technique, (autotransplants for alveoli in the initial phase of healing). In each surgical techniques were applied, randomly, either saline solution or Emdogain ®. Study Design:The study group comprised 26 patents, in which 28 teeth were transplanted to recipient sockets prepared mechanically. Of the 28 teeth transplanted, 4 were intentional replants, and of the remainer, 11 had the apex closed and 13 open. The mean age at the time of transplantation was 22.34±8.14 years (mean ± SD). The transplantation were performed by the same operator, with the informed consent of the patient and authorized by the ethical committee of the hospital. Clinical and radiological examinations were performed during 24 to 65 months (48±12.96; MED±SD), from 10 days, 1 month, 3 months, 6 months and annually to 5.6 years. Results: Only two transplanted teeth were lost, due persistent apical periodontitis, and one transplanted patient with open apex missed the treatment. In the teeth with pulp, we needed to perform root canal therapy in 9. In the 73% of the teeth with closed apex, we needed to perform root canal treatment, with no statistically significant difference found among closed apex and root canal therapy (p=0.083). In only 8% of the teeth with open apex did we need to perform root canal treatment, with an association between open apex and root canal therapy (p=0.0002). The overall success rate was 98% with significant difference for losses (p=0.0001). Conclusions: Although not a frequent procedure, it was concluded that autotransplanted teeth, performed with appropriate surgical care had a good prognosis, and can render a very useful service to the patients. © Medicina Oral S.

The impact of aquatic exercise programs on the intima-media thickness of the carotid arteries, hemodynamic parameters, lipid profile and chemokines of community-dwelling older persons: a randomized controlled trial

Scientific evidence has shown that physical exercise is an effective way of improving several cardiovascular disease markers. However, few studies have tested its effectiveness whenperformed in aquatic environments. The purpose of this study was to test the impact of different aquatic exercise programs on the intima-media thickness of carotid arteries (IMT) and hemodynamic and biochemical markers of cardiovascular diseases in community-dwelling older persons. A total of 102 participants were randomly allocated into four groups: an aerobic exercise group (AerG) (n = 25, 71.44 ± 4.84 years); an aerobic interval group (IntG) (n = 28, 72.64 ± 5.22 years); a combined group (ComG) (n = 29, 71.90 ± 5.67 years); and a control group (CG) (n = 20, 73.60 ± 5.25 years). The AerG, IntG, and ComG participants took part in three different aquatic exercise programs for 28 weeks. The CG participants maintained their usual routines. All participants were evaluated for IMT, blood pressure, lipid profile, and MCP-1 and MIP-1α chemokines, pre- and post-intervention. Significant differences were found in the AerG for diastolic diameter (DD), in the IntG for peak systolic velocity (PSV), and in the ComG for DD and end-diastolic velocity (EDV). Regarding blood pressure, significant differences were found in AerG for systolic blood pressure (SBP) and diastolic blood pressure (DBP); in IntG for DBP; and in ComG for SBP, DBP, and heart rate (HR). Significant differences were found in the AerG and IntG for glucose (GLU). Lower plasma levels of monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein (MIP-1α) were found in the AerG and in the ComG for MCP-1 after the intervention. Aquatic physical exercise appears to improve cardiovascular health, regardless of the type of the program adopted. Aerobic programs (combined and continuous aerobic exercises) seemed to have a more beneficial effect in reducing important cardiovascular risk markers.info:eu-repo/semantics/publishedVersio

Impact of different aquatic exercise programs on body composition, functional fitness and cognitive function of non-institutionalized elderly adults: a randomized controlled trial

Aquatic physical exercise programs have become progressively more popular among elderly people. Some of the major physical exercise program disadvantages on land are minimized due to the specific properties of the aquatic environment. The purpose of the present randomized controlled study is to verify the effects of different aquatic physical exercise programs on body composition, functional fitness and cognitive function in non-institutionalized elderly people. For this study, 102 elderly individuals were randomly allocated into four different groups: AerG (n = 25, 71.44 ± 4.84 years); IntG (n = 28, 72.64 ± 5.22 years); ComG (n = 29, 71.90 ± 5.67 years) and CG (n = 20, 73.60 ± 5.25 years). Individuals from the groups AerG, IntG and ComG participated in three different aquatic physical exercise programs for a period of 28 weeks. The CG participants kept to their usual routines. All participants were evaluated for body composition, functional fitness and cognitive function at two time moments, i.e., pre- (M1) and post-intervention (M2). Significant differences for body composition were found between M1 and M2 for FM (p < 0.001), LBM (p < 0.001) and WCir (p < 0.01) in the AerG, for BMI (p < 0.05), FM (p < 0.05), LBM (p < 0.001) and LCir-R (p < 0.05) in the IntG, and for WGT (p < 0.01), FM (p < 0.05), LBM (p < 0.01), LCir-R (p < 0.05) and LCir-L (p < 0.01) in the ComG groups. For functional fitness, differences were found between M1 and M2 for 2m-ST (p < 0.000), 30s-CS (p < 0.000), 30s-AC (p < 0.05), HG-T-R (p < 0.000) and HG-T-L (p < 0.000) in the AerG, for 2m-ST (p < 0.05), BS-R (p < 0.05), 30s-CS (p < 0.000), 30s-AC(p < 0.01), HG-T-R (p < 0.000) and HG-T-L (p < 0.000) in the IntG, and for 30s-CS (p < 0.000), HG-T-R (p < 0.000) and HG-T-L (p < 0.000) in the ComG groups. The present study evidenced the beneficial effects of physical exercise in an aquatic environment on body composition, functional fitness and cognitive function in non-institutionalized elderly adults. The ComG water-based exercise program showed more beneficial effects in the improvement of body composition and cognitive function variables, while the IntG and AerG programs were more effective in the improvement of functional fitness.info:eu-repo/semantics/publishedVersio

Efeito do exercício físico na qualidade de vida após a cirurgia para cancro do pulmão e cancro colorretal: Revisão sistemática

Introdução: O cancro colorretal (CCR) e o cancro do pulmão são atualmente dois dos tumores mais incidentes a nível global e os mais mortais. Apesar da resseção cirúrgica ser uma intervenção potencialmente curativa em pacientes com estes tumores, esta intervenção está associada a um declínio significativo na qualidade de vida relacionada com a saúde (QVRS). O exercício físico (EF) tem demonstrado um efeito benéfico na melhoria da capacidade funcional dos pacientes elegíveis para estes tipos de cirurgia oncológica, desconhecendo-se, no entanto, o seu efeito na recuperação da QVRS. Objectivo: O objetivo principal desta revisão sistemática foi avaliar a eficácia do EF na melhoria da QVRS após a cirurgia, em pacientes diagnosticados cancro do pulmão ou com CCR. Métodos: Foram incluídos estudos randomizados controlados, publicados até 21 de Março de 2021, selecionados através de pesquisa eletrónica, realizada nas bases de dados PubMed, Scopus, Web of Science, SPORTDiscus e PEDro. Os estudos elegíveis teriam de comparar o efeito de intervenções com EF, implementado no período pré-cirúrgico ou nos três primeiros meses após a cirurgia, com intervenções que não envolvessem exercício estruturado durante este período. A qualidade metodológica foi avaliada através da escala Physiotherapy Evidence Database (PEDro). Resultados: Dez estudos cumpriram com os critérios de elegibilidade e obtiveram uma pontuação ≥ 5 (0-10) na escala PEDro. Nove estudos incluíram pacientes com cancro do pulmão (n=651) e um estudo pacientes com CCR (n=93). Em pacientes com cancro do pulmão o exercício físico melhorou significativamente a dimensão física da QVRS após a cirurgia, com um efeito de magnitude elevada (SMD=0.89: 95% CI: [0.61; 1.15]; p=0.00) e reduziu significativamente os sintomas de fadiga, com um efeito de magnitude moderada SMD=-0.30: 95% CI: [-0.51;-0.08]; p=0.01). Em pacientes com CCR não se verificaram alterações significativas na QVRS nem nos sintomas de fadiga. Conclusão: O EF revela ser uma intervenção eficaz na recuperação da QVRS após a cirurgia em pacientes com cancro do pulmão, não havendo evidência do seu efeito benéfico em pacientes com CCR.N/
