RESUMO
Adapting and providing quality services for people as they age is a common challenge across Europe. The perspective of older people is fundamental in a person-centred care approach. Expanding research at the European level that explicitly includes their views can offer a relevant contribution to the development of evidence-based guidelines that can be shared in education and training across health and social care professions. This study aimed to identify common meaningful dimensions of professional competence in health and social care emphasised by older people from six countries in different regions of Europe according to their experiences. A qualitative approach was chosen with a total of 95 semi-structured interviews conducted in Austria, Finland, Lithuania, Portugal, Turkey and UK, following a common topic guide. Participants in this study were aged 60 and above, and recruitment considered age, gender, level of education and living arrangements. Results identified a set of universal skills and practices that according to older people, health and social care professionals should meet. Competences at the interpersonal level were central in older people's discourses, and its core dimensions are anchored in relational, communication and socio-emotional skills of professionals. These findings reinforce the aspiration of establishing best practices in care that relies on the harmonisation of a competence framework that can be shared in the training and education of health and social care professionals across Europe and that voices older people's preferences, expectations and needs.
RESUMO
UNLABELLED: The CD20 cell surface antigen is expressed at high levels by over 90% of B-cell non-Hodgkin lymphomas (NHL) and is the target of the anti-CD20 monoclonal antibody rituximab. To provide more sensitive, tumor-specific PET imaging of NHL, we sought to develop PET agents targeting CD20. METHODS: Two recombinant anti-CD20 rituximab fragments, a minibody (scFv-C(H)3 dimer; 80 kDa) and a modified scFv-Fc fragment (105 kDa), designed to clear rapidly, were generated. Both fragments were radiolabeled with (124)I, and the minibody was additionally labeled with (64)Cu (radiometal) after conjugation to 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid (DOTA). The radioiodinated fragments and the radiometal-labeled minibody were evaluated in mice as small-animal PET imaging agents for the in vivo imaging of human CD20-expressing lymphomas. RESULTS: Rapid and specific localization to CD20-positive tumors was observed with the radioiodinated fragments. However, the tumor uptake levels and blood activities differed, resulting in different levels of contrast in the images. The better candidate was the minibody, with superior uptake (2-fold higher than that obtained with scFv-Fc) in CD20-positive tumors and low uptake in CD20-negative tumors. Ratios of CD20-positive tumors to CD20-negative tumors at 21 h were 7.0 +/- 3.1 (mean +/- SD) and 3.9 +/- 0.7 for the minibody and scFv-Fc, respectively. The ratio achieved with the (64)Cu-DOTA-minibody at 19 h was about 5-fold lower because of higher residual background activity in CD20-negative tumors. CONCLUSION: A radioiodinated minibody and a radioiodinated scFv-Fc fragment produced excellent, high-contrast images in vivo. These new immunoPET agents may prove useful for imaging CD20-positive lymphomas in preclinical models and in humans with NHL.
