The mechanical effect of the existing cement mantle on the in-cement femoral revision

Cement-in-cement revision hip arthroplasty is an increasingly popular technique to replace a loose femoral stem which retains much of the original cement mantle. However, some concern exists regarding the retention of the existing fatigued and aged cement in such cement-in-cement revisions. This study investigates whether leaving an existing fatigued and aged cement mantle degrades the mechanical performance of a cement-in-cement revision construct.

Análisis de las tendencias del sector de artes gráficas colombiano para el diseño de un plan estratégico de la empresa Editorial Edeco Ltda.

El presente texto expone el análisis del sector de artes gráficas, un sector que continúa en crecimiento y trae consigo nuevas tendencias y retos para las empresas, como por ejemplo la digitalización de contenidos, impresión por demanda, conciencia medioambiental, entre otros. Adicionalmente se expone las diferentes oportunidades y amenazas del sector, la competencia como una variable que afecta directamente la rentabilidad; debido a la guerra de precios existente y la Comoditización de productos y servicios. En el marco teórico se estudian herramientas como DOFA, matriz de Ansoff, benchmarking y primordialmente el análisis estructural de sectores estratégicos, que permite construir una percepción amplia de lo que ocurre en el sector, de tal forma que la empresa pueda replantear su modelo de negocio y pueda construir valor. Se realizaran propuestas de estrategias a desarrollar, con el fin de visualizar nuevos modelos de negocio que en el largo plazo garanticen la supervivencia del negocio, desde un enfoque de adaptación a las nuevas tendencias; así mismo se busca estudiar la posibilidad de entrar en el mundo de la digitalización de contenidos y la creación de nuevos productos que atiendan a los mismos segmentos de clientes actuales de una forma diferente.

How reliable is internet-based self-reported identity, socio-demographic and obesity measures in European adults?

In e-health intervention studies, there are concerns about the reliability of internet-based, self-reported (SR) data and about the potential for identity fraud. This study introduced and tested a novel procedure for assessing the validity of internet-based, SR identity and validated anthropometric and demographic data via measurements performed face-to-face in a validation study (VS). Participants (n = 140) from seven European countries, participating in the Food4Me intervention study which aimed to test the efficacy of personalised nutrition approaches delivered via the internet, were invited to take part in the VS. Participants visited a research centre in each country within 2 weeks of providing SR data via the internet. Participants received detailed instructions on how to perform each measurement. Individual’s identity was checked visually and by repeated collection and analysis of buccal cell DNA for 33 genetic variants. Validation of identity using genomic information showed perfect concordance between SR and VS. Similar results were found for demographic data (age and sex verification). We observed strong intra-class correlation coefficients between SR and VS for anthropometric data (height 0.990, weight 0.994 and BMI 0.983). However, internet-based SR weight was under-reported (Δ −0.70 kg [−3.6 to 2.1], p < 0.0001) and, therefore, BMI was lower for SR data (Δ −0.29 kg m−2 [−1.5 to 1.0], p < 0.0001). BMI classification was correct in 93 % of cases. We demonstrate the utility of genotype information for detection of possible identity fraud in e-health studies and confirm the reliability of internet-based, SR anthropometric and demographic data collected in the Food4Me study.

Learning from the experts: exploring playground experience and activities using a write and draw technique

Background: Qualitative research into the effect of school recess on children’s physical activity is currently limited. This study used a write and draw technique to explore children’s perceptions of physical activity opportunities during recess.

Methods: 299 children age 7–11 years from 3 primary schools were enlisted. Children were grouped into Years 3 & 4 and Years 5 & 6 and completed a write and draw task focusing on likes and dislikes. Pen profiles were used to analyze the data.

Results: Results indicated ‘likes’ focused on play, positive social interaction, and games across both age groups but showed an increasing dominance of games with an appreciation for being outdoors with age. ‘Dislikes’ focused on dysfunctional interactions linked with bullying, membership, equipment, and conflict for playground space. Football was a dominant feature across both age groups and ‘likes/dislikes’ that caused conflict and dominated the physically active games undertaken.

Conclusion: Recess was important for the development of conflict management and social skills and contributed to physical activity engagement. The findings contradict suggestions that time spent in recess should be reduced because of behavioral issues.
