Introduction Breast cancer has innumerable consequences in women’s lives and physical activity can be beneficial during this period. Objectives To analyze the influence of belly dancing on the body image and self-esteem of women during and after breast cancer treatment. Methods Nineteen women diagnosed with breast cancer, divided into a control group (8 women) and a study group (11 women), who were under treatment or post-treatment at the Center for Oncological Research (CEPON), participated in the study. A questionnaire was used for data collection, divided into three blocks as follows: a) general information - sociodemographic and clinical characterization; b) body image - Body Image After Breast Cancer; and c) self-esteem - Rosenberg Self-Esteem Scale. The study group underwent a belly dance intervention consisting of 60-minute classes, twice a week, for a total period of 12 weeks. Women in the control group only maintained their routine activities. Results Significant changes were observed in the improvement of body image in the belly dance group in the pre- and post-intervention periods in the body stigma (p = 0.017) and transparency (p = 0.021) scales. There were no changes in regards to self-esteem. The control group had no changes in either body image or self-esteem. Conclusion The influence of belly dancing on the improvement of women’s body image was observed after 12 weeks of intervention. Thus, it is understood that physical activity may help these women after breast cancer, and should be encouraged by health professionals in this field. Level of evidence II; Therapeutic studies - Investigation of treatment results.

Introdução: O tratamento cirúrgico do câncer de mama pode levar a consequências físicas no membro superior de sobreviventes. Objetivo: Analisar a funcionalidade do membro superior após cirurgia de câncer de mama em sobreviventes do Sul do Brasil. Método: Foram avaliadas 82 sobreviventes de câncer de mama (55±10 anos) em tratamento com hormonioterapia. Foi aplicado um questionário para informações gerais, dor (Escala Visual Analógica) e funcionalidade do membro superior (DASH), seguido de testes físicos; amplitude de movimento (goniômetro), força (dinamômetro), propriocepção (cinesiômetro) e volume do braço (perímetro do braço). Resultados: Não foram encontradas diferenças para nenhuma das variáveis de funcionalidade em relação à mastectomia ou cirurgia conservadora de mama. No entanto, melhores escores de força e amplitude de movimento foram apresentados no membro contralateral a cirurgia. A regressão linear demonstrou uma relação entre dor, força, amplitude de movimento, propriocepção e volume do braço com as disfunções do membro superior e, quando ajustada pela modalidade de cirurgia, apenas a amplitude de movimento, volume do braço e propriocepção mantiveram-se significativamente. Conclusão: A cirurgia do câncer de mama pode levar a pior funcionalidade no membro superior, independentemente da modalidade da cirurgia. Os resultados elucidam a necessidade de um programa eficiente de pós-tratamento para prevenir as consequências na função física do membro superior após cirurgia de câncer de mama e proporcionar melhora nas atividades de vida diária nessa populaçao.

The seed yield of guarana (Paullinia cupana H.B.K. var. sorbilis) is affected by weeds. Management is difficult for Amazon farmers and ranchers, owing to the hot and humid climate prevailing in the region, which makes mechanical control inefficient and leads farmers to the decision to use herbicides. Herbicide damage to this species is unknown. The objective of this study was to evaluate glyphosate damage to the development and quality of guarana seedlings. The treatments consisted of glyphosate doses at concentrations of 0, 126, 252, 540, 1080, 2160 and 3240 g a.e. ha−1 and were evaluated for 60 days, in two applications. Analyses were performed for biometrics, seedling development, anthracnose and Injury characteristics. Glyphosate caused symptoms of Injury in all doses applied, but lower doses did not interfere with seedling growth and development. There was a correlation between anthracnose severity and increased glyphosate dose. When applied correctly, glyphosate can be an integrated weed management tool for use in guarana crops.
