Translation and Validation of the Patient Activation Measure in Portuguese People with Type 2 Diabetes Mellitus

Introduction: Management of diabetes mellitus is largely dependent on patients' active participation in care. The 'Patient Activation Measure 13' assesses patients' knowledge, skills, and confidence in self-care. We aimed to translate, culturally adapt, and validate the 'Patient Activation Measure 13' to Portuguese, in people with type 2 diabetes. Material and Methods: The translation and cultural adaptation occurred in six phases. A convenience sample of people with type 2 diabetes was recruited from the waiting rooms of a diabetes outpatient centre in Lisbon, between March and April 2014. The questionnaire was self-administered; medical records were reviewed to obtain glycated haemoglobin levels. Main statistical analyses were based on the Rasch rating scale model. Results: The response rate for the final questionnaire was 76%. Rasch analysis was conducted on 193 respondents. Respondents had a mean age of 67.1 (SD 10.1) years, 42.7% were women, and the mean patient activation measure score (0 - 100) in the sample was 58.5 (SD 10.1). The sample was low to moderate in terms of activation: 40.4% were low in activation (levels 1 and 2), 49.7% were in level 3, and 9.8% were in level 4, the highest level of activation. All items had good fit and the response categories functioned well. Item reliability was 0.97 and person reliability was between 0.77 (real) and 0.83 (model). Discussion: The 'Patient Activation Measure 13' was translated and culturally adapted to European Portuguese and validated in people with diabetes, showing good psychometric properties. Future research should aim at evaluating test-retest reliability of the Portuguese 'Patient Activation Measure 13', and exploring its ability to measure changes in activation over time. Conclusion: The 'Patient Activation Measure 13' is now available in European Portuguese and has good psychometric properties.Liliana Laranjo was supported by a Junior Clinical Research award from the Harvard Medical School-Portugal program (HMSP-ICJ/0005/2010; Fundacao para a Ciencia e Tecnologia)

Filling minimality of Finslerian 2-discs

We prove that every Riemannian metric on the 2-disc such that all its geodesics are minimal, is a minimal filling of its boundary (within the class of fillings homeomorphic to the disc). This improves an earlier result of the author by removing the assumption that the boundary is convex. More generally, we prove this result for Finsler metrics with area defined as the two-dimensional Holmes-Thompson volume. This implies a generalization of Pu's isosystolic inequality to Finsler metrics, both for Holmes-Thompson and Busemann definitions of Finsler area.Comment: 16 pages, v2: improved introduction and formattin

The Schwarzschild-de Sitter solution in five-dimensional general relativity briefly revisited

We briefly revisit the Schwarzschild-de Sitter solution in the context of five-dimensional general relativity. We obtain a class of five-dimensional solutions of Einstein vacuum field equations into which the four-dimensional Schwarzschild-de Sitter space can be locally and isometrically embedded. We show that this class of solutions is well-behaved in the limit of lambda approaching zero. Applying the same procedure to the de Sitter cosmological model in five dimensions we obtain a class of embedding spaces which are similarly well-behaved in this limit. These examples demonstrate that the presence of a non-zero cosmological constant does not in general impose a rigid relation between the (3+1) and (4+1)-dimensional spacetimes, with degenerate limiting behaviour.Comment: 7 page

Qualidade biológica do solo após adição de pó de balão e cultivo do milho: I - População e atividade de microrganismos.

O pó de balão ou charcok, resíduo da indústria siderúrgica não integrada a carvão vegetal enquadrado na Classe I e considerado perigoso, tem sido recomendado na cultura de eucalipto, na dosagem de 50 t ha-1. Nesse trabalho, procurou-se analisar os impactos da aplicação deste resíduo sobre a qualidade do solo cultivado com milho, medidos através da densidade populacional de fungos, bactérias e actinomicetos e hidrólise do diacetato de fluoresceína (FDA). Foram avaliados seis tratamentos constituídos de doses de pó de balão equivalentes a 0, 25, 50, 75, 100 t ha-1, na presença de adubação e de 50 t ha-1 de pó de balão, na ausência de adubação, distribuídos em delineamento de blocos casualizados, em três repetições. As amostras de solo foram coletadas após a colheita das plantas de milho, efetuada aos 60 dias de idade. Os resultados obtidos demonstraram que não houve diferença significativa na composição qualitativa e quantitativa e atividade dos microrganismos, independente das dosagens de pó de balão utilizadas. Concluiu-se que a aplicação de pó de balão não afetou a qualidade biológica do solo através dos bioindicadores utilizados, mesmo na dosagem 100 t ha-1, equivalente ao dobro da recomendada

HEI teaching mobility: looking for dynamics in a seven-year period

Higher Education Institutions are currently embracing mobility as an imperative goal, particularly and most impressively in the European Union countries where programs such as Erasmus+ strongly encourage students and staff to participate. This exploratory research aims to characterize teaching mobility in one university, identify facilitators, determine outcomes of repeated mobility, and provide clues on mobility dynamics over time. Qualitative and quantitative data were collected from application forms and final reports submitted by 107 outgoing and 58 incoming teachers in one university between 2009 and 2016. It was observed that teaching mobility covers diversified profiles (e.g., gender, seniority, and fields of study). 23 out of 71 outgoing teachers participated in more than one mobility program during that period. A deeper analysis on the mobility champions reveals both individual and team initiatives. The results provide some interesting data on facilitators and consequences of teaching mobility.publishe
