Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Characterising integrated content-language pedagogies of global perspectives teachers in Dutch bilingual schools

This study aims to characterise teachers’ integrated content-language learning pedagogies teaching the skills-focused subject Global Perspectives (GP) in Dutch bilingual upper-secondary-schools. Eleven teachers from seven bilingual schools across the Netherlands participated in the study in the school-year 2016-2017. To obtain insight into teachers’ pedagogies, semi-structured interviews and observations of GP lessons were used. Dalton Puffer’s Cognitive Discourse Functions (CDF) construct [(2013). A construct of cognitive discourse functions for conceptualizing content-language integration in CLIL and multilingual education. European Journal of Applied Linguistics, 1(2), 216–253. https://doi.org/10.1515/eujal-2013-0011], in combination with a focus on subject-specific Culture, was used as a heuristic to analyse the integrated content-language pedagogies of teachers. Main findings include that the participating schools had three distinct Intended Curriculum foci and, within these, five different types of integrated content-language learning pedagogies were identified. Main implications discussed are that focusing on subject-specific culture and using the CDF Construct is a useful heuristic to allow analysis of teachers’ integrated content-language pedagogies, and that it may also provide a useful framework for both pre- and in-service teachers in CLIL contexts to emphasise the integrated nature of CLIL teaching.
