Translation and validation of the Dutch version of the Effective Consumer Scale (EC-17)

PURPOSE: The Effective Consumer Scale (EC-17) measures the skills of musculoskeletal patients in managing their own healthcare. The objectives of this study were to translate the EC-17 into Dutch and to further evaluate its psychometric properties. METHODS: The EC-17 was translated and cognitively pretested following cross-cultural adaptation guidelines. Two hundred and thirty-eight outpatients (52 % response rate) with osteoarthritis or fibromyalgia completed the EC-17 along with other validated measures. Three weeks later, 101 patients completed the EC-17 again. RESULTS: Confirmatory factor analysis supported the unidimensional structure of the scale. The items adequately fit the Rasch model and only one item demonstrated differential item functioning. Person reliability was high (0.92), but item difficulty levels tended to cluster around the middle of the scale, and measurement precision was highest for moderate and lower levels of skills. The scale demonstrated adequate test-retest reliability (ICC = 0.71), and correlations with other measures were largely as expected. CONCLUSION: The results supported the validity and reliability of the Dutch version of the EC-17, but suggest that the scale is best targeted at patients with relatively low levels of skills. Future studies should further examine its sensitivity to change in a clinical trial specifically aimed at improving effective consumer skills

Good results with cemented total hip arthroplasty in patients between 40 and 50 years of age: 168 hips followed for 2–19 years

Background and purpose Total hip arthroplasties in young patients have lower long-term survival rates than in older patients. We evaluated the use of a unique treatment protocol in patients aged between 40 and 50 years. In all cases we used a cemented THA, and for acetabular deficiencies we also used impacted bone grafts together with a cemented cup

Feminist Experiences of ‘Studying up’: Encounters with International Institutions

Feminist Experiences of \u27Studying up\u27: Encounters with International Institutions This article makes the case for feminist IR to build knowledge of international institutions. It emerges from a roundtable titled ‘Challenges and Opportunities for Feminist IR: Researching Gendered Institutions’ which took place at the International Studies Association Annual Convention in Baltimore in 2017. Here, we engage in self-reflexivity, drawing upon our conversation to consider what it means for feminist scholars to ‘study up’. We argue that feminist IR conceptions of narratives and the everyday make a valuable contribution to feminist institutionalist understandings of the formal and informal. We also draw attention to the value of postcolonial approaches, and multi-site analysis of international institutions for creating a counter-narrative to hegemonic accounts emerging from both the institutions themselves, and scholars studying them without a critical feminist perspective. In so doing, we draw attention to the salience of considering not just what we study as feminist International Relations scholars but how we study it. Spanish Experiencias feministas de \uabEstudiar a los de arriba\ubb: encuentros con instituciones internacionales Este art\uedculo plantea el argumento de que las relaciones internacionales (RR.

Argumentamos que las concepciones feministas de las RR.

Tambi\ue9n queremos destacar el valor de los enfoques poscoloniales y el an\ue1lisis de m\ufaltiples ubicaciones de las instituciones internacionales para crear un contrarrelato frente a los discursos hegem\uf3nicos que se derivan tanto de las propias instituciones como de los acad\ue9micos que las estudian sin una perspectiva feminista cr\uedtica. Al hacerlo, pretendemos destacar la trascendencia de tener en cuenta no solo lo que estudiamos como acad\ue9micos feministas de Relaciones Internacionales, sino tambi\ue9n c\uf3mo lo estudiamos.Palabras clave: g\ue9nero, instituciones internacionales, relaciones internacionales feministas French Exp\ue9riences f\ue9ministes de \uab studying up \ubb : \uc0 la rencontre des institutions internationalesCet article affirme la n\ue9cessit\ue9 pour l’approche f\ue9ministe des RI de renforcer le savoir en mati\ue8re d’institutions internationales.

Revisions of Extensive Acetabular Defects with Impaction Grafting and a Cement Cup

Item does not contain fulltextBACKGROUND: Loosening of acetabular components often leads to bony defects. Management of extensive acetabular bone loss in hip revision arthroplasty can be a tremendous challenge. QUESTIONS/PURPOSES: We asked whether a reconstruction with impacted bone grafts will provide a durable and pain-free function in extensive acetabular defects. We specifically determined the (1) survival rates with the end point of revision for any reason, aseptic revision, and radiographic loosening; (2) visual analog scale (VAS) pain score, Harris hip score (HHS), and the Oxford Hip Questionnaire score (OHQS); (3) number of repeat revisions; (4) complications; and (5) radiographic loosening, wear, and radiolucencies. PATIENTS AND METHODS: We retrospectively followed 25 patients (27 hips) with extensive acetabular defects. No patient was lost to followup. Two patients died during followup. Minimum followup was 3 years (mean, 8.8 years; range, 3-14.1 years). RESULTS: Three patients (three hips) underwent repeat revision surgery and another two patients (two hips) had radiographically loose hips. The 10-year survival rate was 88% (95% confidence interval, 74.2%-100%) with the end point acetabular revision for any reason and 95% (95% confidence interval, 86.0%-100%) with the end point acetabular revision for aseptic loosening. The mean HHSs were 55 points before surgery and 72 points postoperatively. CONCLUSIONS: Acetabular reconstruction with impaction bone grafting and a cemented cup is a reliable technique with a 10-year survival rate of 88% in patients with extensive acetabular deficiencies.
