Radiation Oncology , 2009, DOI: 10.1186/1748-717x-4-70
Abstract: Forty CT-based 3D-APBI plans were retrieved on which a total of 4 radiation oncologists, two trainee and two experienced physicians, outlined the lumpectomy cavity. The inter-observer variability of LC contouring was assessed when the CTV was defined as the delineation that encompassed both surgical clips and remodelled breast tissue.The conformity index of tumour bed delineation was significantly improved by the placement of surgical clips within the LC (median at 0.65). Furthermore, a better conformity index of LC was observed according to the experience of the physicians (median CI = 0.55 for trainee physicians vs 0.65 for experienced physicians).The placement of surgical clips improved the accuracy of lumpectomy cavity delineation in 3D-APBI. However, a learning curve is needed to improve the conformity index of the lumpectomy cavity.Accelerated Partial Breast Irradiation (APBI) is still under investigation to demonstrate equivalence to whole breast irradiation in terms of local control. Among the different APBI techniques (invasive or non-invasive), 3D-conformal APBI is widely used given its accessibility in radiotherapy centres [1]. However, several issues related to this technique still warrant investigation: e.g. the identification and contouring of the lumpectomy cavity (LC), the patient's set-up and optimal dose determination. The definition of the lumpectomy cavity is an essential part of 3D-conformal APBI treatment planning as the irradiation is confined to a limited volume of breast tissue adjacent to the lumpectomy cavity. Unlike intra-operative partial breast irradiation, LC determination is critical as treatment delivery is delayed after breast surgery. In 3D-APBI, the GTV (Gross Tumour Volume) and CTV (Clinical Target Volume) are generally defined as the contouring of a seroma within the lumpectomy cavity, expanded by a 1 cm margin [2,3]. However, the delineation of the seroma could vary among different observers and even among experienced ones[4].I

Identificando a branquidade inominada: corpo, ra?a e na??o nas representa??es sobre Gisele Bündchen na mídia transnacional
Maia, Suzana;
Cadernos Pagu , 2012, DOI: 10.1590/S0104-83332012000100011
Abstract: this article examines the discursive configurations that associate the body of top model gisele bündchen to the body of the brazilian nation, and analyses the ways through which these configurations define what means to be brazilian according to discourses that circulate in brazilian and transnational media. in order to do that, i use images of gisele to interrogate the racial formations in the two contexts and to examine how theses formations are being reconfigured due to recent changes in the demographic and political contexts in brazil and in the united states. following the studies of racial relations in the two countries, i adopt a framework developed by the studies that focus on the construction of whiteness.

O apoio domiciliário a pessoas infectadas pelo VIH em Fran?a e em Portugal
Maia,Marta;

Abstract: aids is a disease that exists for more than twenty years. with the arrival of tritherapies, this disease became chronic but still remains a very serious one, that many times is handicapping and its treatments are ?heavy? and the secondary effects hardly bearable. within this context social support is fundamental for the individuals that are infected. the care support at patients? homes is a very important element for those who live with aids. the associative mobilization towards aids is important but not always sufficient in portugal, as we tried to demonstrate comparing some aspects of state financial help and domiciliary care support between france and portugal.

Arquivos de Medicina , 2006,
Abstract: the treatment of hepatitis c consists of a bitherapy of pegylated interferon and ribavirin. this treatment causes numerous and strong side effects. in this context, i tried to evaluate the perception that the patient has of himself and of the others, the influence of the illness, of the treatment and the cure not only in his daily life but also in his identity as a patient. the investigation assembles on testimonies in internet discussion forums and interviews of patients found at these forums.
Representa??o política de atores cívicos entre a imediaticidade da experiência e discursos de justifica??o
Maia, Rousiley;
Revista Brasileira de Ciências Sociais , 2012, DOI: 10.1590/S0102-69092012000100007
Abstract: this article investigates the legitimacy building process concerning the representation in the civil society. based on the recognition theory, the author defends the importance of the subjective experiences for a well-succeeded identification of different forms of injustice. firstly, the author contends that the subjective experience, although being regarded as a necessary and irreplaceable source of intelligibility of injustice, cannot become a reliable source of justification in the public sphere. secondly, the author investigates different forms of representation which become overlapped in the civil sphere and the need to articulate them with electoral representation and traditional dynamics of representative politics. finally, the author discusses some manner to institutionalize the representation coming from civil society participation, in order to produce democratic effects in the organization of social life.
Sedu??o e identidade nacional: dan?arinas eróticas brasileiras no Queens, Nova York
Maia, Suzana;
Revista Estudos Feministas , 2009, DOI: 10.1590/S0104-026X2009000300009
Abstract: this article examines the trajectory of brazilian women who work as erotic dancers in new york city's gentlemen's bars. it argues that processes of globalization and transnationalism are related not just with political-economic transformations, but also to significant shifts in the ways people relate to each other, use their bodies, and conceive and realize their desires. such transformations must also be understood in relation to a colonial and post-colonial regime, in which representations about their bodies gain intelligibility. most of the women who participated in my research are from the middle-classes, and in terms of race, they self-identify as "morenas". based on fieldwork conducted between years 2004-2005, i analyze how their social positioning and identity are translated from one context to another, and how new social hierarchies are constructed in a transnational context. taking as a focus of study blue diamond, a bar located in the borough of queens, this article investigates how these transnational reconfigurations are articulated through particular relationships among dancers and between dancers and clients
Altruísmo e educa??o: condi??o, consciência e dignidade
Maia,Carlos;
Revista Portuguesa de Educa??o , 2006,
Abstract: the educational act reveals a person?s altruistic structure and dynamism. individual as well as collective benefit relies on this act on behalf of both unfavoured and favoured people.there is no sense or reason to aiming at surpassing the limitations of the first without maximizing the potentialities of the last. but the effort towards enhancing maximum skills is bigger than the one oriented towards rousing minimum skills. not to pursue the objective of developing a person?s maximum skills is to deny altruism and to promote an attitude of anthropological, pedagogical and ethical indifference, masked it could be under tolerance.
