Exercício físico e cancro da mama: uma revisão

Introdução – Os efeitos fisiológicos da atividade física e do treino são atualmente motivo de extensa investigação cujos resultados mostraram já de forma incontroversa os seus benefícios em diferentes condições clínicas. Diferentes estudos mostraram já os efeitos benéficos do exercício regular de intensidade leve a moderada na diminuição do risco de cancro, bem como na aptidão física de indivíduos portadores de cancro, submetidos ou não a cirurgia. A prescrição do exercício mais adequado para a sua maior eficácia na melhoria da aptidão física e para a diminuição da fadiga não é, no entanto, ainda consensual. O objetivo deste estudo foi o de rever o conhecimento atual sobre os benefícios do exercício físico em sobreviventes de cancro da mama, bem como sistematizar as linhas orientadoras atuais para a prescrição do exercício físico na referida população. Metodologia – Recorreu-se a uma revisão da literatura, tendo como base as palavras-chave: cancro da mama, sobreviventes de cancro da mama, risco de cancro, exercício físico, atividade física e treino, dando preferência a estudos que, na classificação de Oxford, correspondessem aos níveis I (ensaios clínicos randomizados e revisões sistemáticas) e II de evidência científica (ensaios clínicos não randomizados). Conclusão – Embora se reconheça que o exercício físico é benéfico para a população em geral e existam linhas orientadoras para a prescrição do exercício físico em indivíduos com cancro, estas não são ainda absolutamente consensuais, necessitando sempre de individualização no treino. A investigação em torno das questões que envolvem a adequada prescrição do exercício físico em indivíduos com ou em risco de desenvolver cancro é primordial. ABSTRACT - Introduction – Physiological effects of physical activity and training are currently subject of extensive research which has already showed uncontroversial benefits in different clinical conditions. Different studies have already shown the beneficial effects of mild to moderate regular exercise in decreasing cancer risk and increasing physical fitness of individuals suffering from cancer, undergoing surgery or not. However, the appropriate exercise prescription for greater efficacy in improving physical fitness and decreasing fatigue is not yet consensus. The aim of this study was to review current knowledge about the benefits of exercise on breast cancer survivors and systematize the existing guidelines for prescribing exercise in this population. Methodology – A literature review was conducted based on the keywords: breast cancer, breast cancer survivors, cancer risk, physical exercise, physical activity and training, giving preference to studies in the classification of Oxford corresponded to level I (randomized clinical trials and systematic reviews) and II (no randomized clinical trials) scientific evidence. Conclusion – Although it is recognized that exercise is beneficial for general population and that there are guidelines for exercise prescription for individuals with cancer, there is no absolute agreement and they constantly require individual adaptations in training. Research on issues involving the correct prescription of exercise for individuals with or at risk of developing cancer is vital.

How new online communication tools and the availability of content influence the audiences and the creative process

We live in a changing world. At an impressive speed, every day new technological resources appear. We increasingly use the Internet to obtain and share information, and new online communication tools are emerging. Each of them encompasses new potential and creates new audiences. In recent years, we witnessed the emergence of Facebook, Twitter, YouTube and other media platforms. They have provided us with an even greater interactivity between sender and receiver, as well as generated a new sense of community. At the same time we also see the availability of content like it never happened before. We are increasingly sharing texts, videos, photos, etc. This poster intends to explore the potential of using these new online communication tools in the cultural sphere to create new audiences, to develop of a new kind of community, to provide information as well as different ways of building organizations’ memory. The transience of performing arts is accompanied by the need to counter that transience by means of documentation. This desire to ‘save’ events reaches its expression with the information archive of the different production moments as well as the opportunity to record the event and present it through, for instance, digital platforms. In this poster we intend to answer the following questions: which online communication tools are being used to engage audiences in the cultural sphere (specifically between theater companies in Lisbon)? Is there a new relationship with the public? Are online communication tools creating a new kind of community? What changes are these tools introducing in the creative process? In what way the availability of content and its archive contribute to the organization memory? Among several references, we will approach the two-way communication model that James E. Grunig & Todd T. Hunt (1984) already presented and the concept of mass self-communication of Manuel Castells (2010). Castells also tells us that we have moved from traditional media to a system of communication networks. For Scott Kirsner (2010), we have entered an era of digital creativity, where artists have the tools to do what they imagined and the public no longer wants to just consume cultural goods, but instead to have a voice and participate. The creativity process is now depending on the public choice as they wander through the screen. It is the receiver who owns an object which can be exchanged. Virtual reality has encouraged the receiver to abandon its position of passive observer and to become a participant agent, which implies a challenge to organizations: inventing new forms of interfaces. Therefore, we intend to find new and effective online tools that can be used by cultural organizations; the best way to manage them; to show how organizations can create a community with the public and how the availability of online content and its archive can contribute to the organizations’ memory.
