Abstract Objective Evaluate the effect of combined training on body image (BI), body composition and functional capacity in patients with breast cancer. As also the relationship of BI with body composition and functional capacity. Methods This was a Controlled Clinical Trial study, this study including 26 patients with breast cancer (30 to 59 years). The training group (n = 13) underwent 12 weeks of training, including three 60-min sessions of aerobic exercise and resistance training, and two sessions of flexibility training per week; each flexibility exercise lasted 20s. The Control Group (n = 13) received only the standard hospital treatment. Participants were evaluated at baseline and after 12 weeks. BI (primary outcomes) was assessed using the Body Image After Breast Cancer Questionnaire; Body composition was estimated with the indicators: Body mass index; Weight, Waist hip Ratio; Waist height ratio; Conicity index; Reciprocal ponderal index; Percentage of fat; Circumference of the abdomen and waist; Functional capacity by cardiorespiratory fitness (cycle ergometer) and strength (manual dynamometer). The statistic was performed in the Biostatistics and Stata 14.0 (α = 5%). Results The patients in the training group showed a reduction in the limitation dimension (p = 0.036) on BI, However, an increase in waist circumference was observed in both groups. In addition an increase in VO2max (p < 0.001) and strength in the right (p = 0.005) and left arms (p = 0.033). Conclusion Combined training demonstrates to be an effective and non-pharmacological strategy to patients with breast cancer, with improvement on BI and functional capacity, changing related variables negatively when there is no physical training.

Resumo Objetivo Avaliar o efeito do treinamento combinado na imagem corporal (IB), composição corporal e capacidade funcional em pacientes com câncer de mama. Assim como a relação do IB com a composição corporal e capacidade funcional. Métodos Este foi um estudo de Ensaio Clínico Controlado, este estudo incluiu 26 pacientes com câncer de mama (30 a 59 anos). O grupo de treinamento (n = 13) foi submetido a 12 semanas de treinamento, incluindo três sessões de 60 min de exercício aeróbio e treinamento de resistência, e duas sessões de treinamento de flexibilidade por semana; cada exercício de flexibilidade durou 20s. O Grupo Controle (n = 13) recebeu apenas o tratamento hospitalar padrão. Os participantes foram avaliados no início e após 12 semanas. O IB (desfechos primários) foi avaliado por meio do Body Image After Breast Cancer Questionnaire; A composição corporal foi estimada com os indicadores: índice de massa corporal; Peso, relação cintura-quadril; Relação da altura da cintura; Índice de conicidade; Índice ponderal recíproco; Porcentagem de gordura; Circunferência do abdômen e cintura; Capacidade funcional por aptidão cardiorrespiratória (cicloergômetro) e força (dinamômetro manual). A estatística foi realizada na Bioestatística e no Stata 14.0 (α = 5%). Resultados Os pacientes do grupo de treinamento apresentaram redução da dimensão da limitação (p = 0,036) no IB, porém, foi observado aumento da circunferência da cintura em ambos os grupos. Além disso, um aumento do VO2máx (p <0,001) e da força nos braços direito (p = 0,005) e esquerdo (p = 0,033). Conclusão O treinamento combinado demonstra ser uma estratégia eficaz e não farmacológica para pacientes com câncer de mama, com melhora do IB e da capacidade funcional, alterando variáveis relacionadas negativamente quando não há treinamento físico.

OBJECTIVE: The aim of this in vitro study was to evaluate the bond strength of different root canal sealers to dentin. MATERIAL AND METHODS: Forty extracted single-rooted human teeth were examined and the coronal and middle thirds of the canals were prepared with a 1.50 mm post drill (FibreKor Post System, Pentron). The teeth were allocated in two experimental groups, irrigated with 2.5% NaOCl+17% EDTA or saline solution (control group) and instrumented using Race rotary files (FKG) to a size #40 at the working length. Then, the groups were divided into four subgroups and filled with Epiphany sealer (Group 1), EndoREZ (Group 2), AH26 (Group 3) and Grossman's Sealer (Group 4). After 2 weeks of storage in 100% humidity at 37ºC, all teeth were sectioned transversally into 2-mm-thick discs. Push-out tests were performed at a cross-head speed of 1 mm/min using a universal testing machine. The maximum load at failure was recorded and expressed in MPa. RESULTS: Means (±SD) in root canals irrigated with 2.5% NaOCl and 17% EDTA were: G1 (21.6±6.0), G2 (15.2±3.7), G3 (14.6±4.5) and G4 (11.7±4.1).Two-way ANOVA and Tukey's test showed the highest bond strength for the Epiphany's group (p< 0.01) when compared to the other tested sealers. Saline solution decreased the values of bond-strength (p<0.05) for all sealers. CONCLUSION: Epiphany sealer presented higher bond strength values to dentin in both irrigating protocols, and the use of 2.5% NaOCl and 17% EDTA increased the bond strength values for all sealers.

O objetivo deste trabalho foi investigar in vitro a atividade antimicrobiana do hidróxido de cálcio em combinação com vários veículos contra alguns microrganismos mais frequentemente isolados dos canais radiculares. A atividade antimicrobiana foi determinada pelo método de difusão no ágar. Cilindros de aço inoxidável foram colocados sobre as placas de agar já inoculadas, dentro dos quais os medicamentos testados e seus controles foram introduzidos. As zonas de inibição do crescimento microbiano foram medidas e anotadas após o período de incubação de cada placa e os resultados foram analisados estatisticamente. A atividade antimicrobiana in vitro dos medicamentos testados, em ordem decrescente, foi: Ca(OH)2 + PMCF + glicerina, Ca(OH)2 + PMCF, Ca(OH)2 + glicerina, Ca(OH)2 + anestésico, Ca(OH)2 + salina, Ca(OH)2 + H2O, Ca(OH)2 + polietilenoglicol. Pastas com veículos oleosos produziram as maiores zonas de inibição, quando comparadas com as com veículos aquosos ou oleosos. Concluimos que a habilidade de difusão e a atividade antimicrobiana do hidróxido de cálcio estão relacionadas com os tipos de veículos utilizados.

The aim of this study was to investigate in vitro the antimicrobial activity of calcium hydroxide in combination with several vehicles against some microorganisms commonly isolated from root canals. Antimicrobial activity was determined by the agar diffusion method. Stainless-steel cylinders were placed on each inoculated agar medium. The test medicaments and their controls were placed inside the cylinders. The zones of growth inhibition were measured and recorded after incubation for each plate and the results were analyzed statistically (ANOVA). The in vitro antimicrobial effects of the medications were ranked from strongest to weakest as follows: Ca(OH)2 + CMCP + glycerine, Ca(OH)2 + CMCP, Ca(OH)2 + glycerine, Ca(OH)2 + anesthetic, Ca(OH)2 + saline, Ca(OH)2 + H2O, Ca(OH)2 + polyethyleneglycol. The pastes with oily vehicles showed significantly larger mean zones of inhibition compared to those with aqueous or viscous vehicles. It was concluded that diffusion and antimicrobial activity of calcium hydroxide were affected by the type of vehicle used.
