- Tumour infiltration by activated natural killer (A-NK) cells is a pre-requisite for tumour eradication by adoptive NK cell transfer. Extravasated A-NK cells do not always succeed in reaching the crucial target cell conjugation. Therefore, we wished to study A-NK cell locomotion and interactions with melanoma cells in a matrix environment (Matrigel) by electron, confocal and fluorescence microscopy. Two distinct patterns of A-NK cell-mediated matrix disintegration were revealed during incubation of tumour cells and A-NK cells in Matrigel: (1) A-NK cells pre-cultured for 5 days altered the homogeneous texture of the Matrigel, an initial microporous appearance became a loose filamentous meshwork by 24 h. Matrix degrading protease inhibitors could not fully prevent this, but could delay the process; and (2) A-NK cells pre-cultured for 6 days or more, instead formed large excavations in the Matrigel leaving the remaining matrix less affected compared to the effects by the younger A-NK cells. By histochemical staining with Cupromeronic Blue, the excavations were shown to contain proteoglycan material. Protease inhibitors had no discernable effect on the development of the excavations. The conspicuous capacity of A-NK cells to disintegrate extracellular matrix and the formation of large excavations seems only partially to depend on matrix-degrading proteases. Formation of extracellular proteoglycan material is suggested to facilitate A-NK cell locomotion within a matrix environment.

- A considerable body of work highlights the relevance of collaborative research, contract research, consulting and informal relationships for university–industry knowledge transfer. We present a systematic review of research on academic scientists’ involvement in these activities to which we refer as ‘academic engagement’. Apart from extracting findings that are generalisable across studies, we ask how academic engagement differs from commercialisation, defined as intellectual property creation and academic entrepreneurship. We identify the individual, organisational and institutional antecedents and consequences of academic engagement, and then compare these findings with the antecedents and consequences of commercialisation. Apart from being more widely practiced, academic engagement is distinct from commercialisation in that it is closely aligned with traditional academic research activities, and pursued by academics to access resources supporting their research agendas. We conclude by identifying future research needs, opportunities for methodological improvement and policy interventions.

- Background: The approach and style of leaders is known to be an important factor influencing the translation of research evidence into nursing practice. However, questions remain as to what types of roles are most effective and the specific mechanisms through which influence is achieved. Objectives: The aim of the study was to enhance understanding of the mechanisms by which key nursing roles lead the implementation of evidence-based practice across different care settings and countries and the contextual factors that influence them. Design: The study employed a qualitative descriptive approach. Settings: Data collection was undertaken in acute care and primary/community health care settings in Australia, Canada, England and Sweden. Participants: 55 individuals representing different levels of the nursing leadership structure (executive to frontline), roles (managers and facilitators), sectors (acute and primary/community) and countries. Methods: Individual semi-structured interviews were conducted with all participants exploring their roles and experiences of leading evidence-based practice. Data were analysed through a process of qualitative content analysis. Results: Different countries had varying structural arrangements and roles to support evidence-based nursing practice. At a cross-country level, three main themes were identified relating to different mechanisms for enacting evidence-based practice, contextual influences at a policy, organisational and service delivery level and challenges of leading evidence-based practice. Conclusions: National policies around quality and performance shape priorities for evidence-based practice, which in turn influences the roles and mechanisms for implementation that are given prominence. There is a need to maintain a balance between the mechanisms of managing and monitoring performance and facilitating critical questioning and reflection in and on practice. This requires a careful blending of managerial and facilitative leadership. The findings have implications for theory, practice, education and research relating to implementation and evidence-based practice. © 2018 Elsevier Ltd

- Aims To describe strategies nursing leaders use to promote evidence-based practice implementation at point-of-care using data from health systems in Australia, Canada, England and Sweden. Design A descriptive, exploratory case-study design based on individual interviews using deductive and inductive thematic analysis and interpretation. Methods Fifty-five nursing leaders from Australia, Canada, England and Sweden were recruited to participate in the study. Data were collected between September 2015 and April 2016. Results Nursing leaders both in formal managerial roles and enabling roles across four country jurisdictions used similar strategies to promote evidence-based practice implementation. Nursing leaders actively promote evidence-based practice implementation, work to influence evidence-based practice implementation processes and integrate evidence-based practice implementation into everyday policy and practices. Conclusion The deliberative, conscious strategies nursing leaders used were consistent across country setting, context and clinical area. These strategies were based on a series of activities and interventions around promoting, influencing and integrating evidence-based practice implementation. We conjecture that these three key strategies may be linked to two overarching ways of demonstrating effective evidence-based practice implementation leadership. The two overarching modes are described as mediating and adapting modes, which reflect complex, dynamic, relationship-focused approaches nursing leaders take towards promoting evidence-based practice implementation. Impact This study explored how nursing leaders promote evidence-based practice implementation. Acknowledging and respecting the complex work of nursing leaders in promoting evidence-based practice implementation through mediating and adapting modes of activity is necessary to improve patient outcomes and system effectiveness.

- Background: Health care practice needs to be underpinned by high quality research evidence, so that the best possible care can be delivered. However, evidence from research is not always utilised in practice. This study used the Promoting Action on Research Implementation in Health Services (PARIHS) framework as its theoretical underpinning to test whether two different approaches to facilitating implementation could affect the use of research evidence in practice. Methods: A pragmatic clustered randomised controlled trial with embedded process and economic evaluation was used. The study took place in four European countries across 24 long-term nursing care sites, for people aged 60years or more with documented urinary incontinence. In each country, sites were randomly allocated to standard dissemination, or one of two different types of facilitation. The primary outcome was the documented percentage compliance with the continence recommendations, assessed at baseline, then at 6, 12, 18, and 24months after the intervention. Data were analysed using STATA15, multi-level mixed-effects linear regression models were fitted to scores for compliance with the continence recommendations, adjusting for clustering. Results: Quantitative data were obtained from reviews of 2313 records. There were no significant differences in the primary outcome (documented compliance with continence recommendations) between study arms and all study arms improved over time. Conclusions: This was the first cross European randomised controlled trial with embedded process evaluation that sought to test different methods of facilitation. There were no statistically significant differences in compliance with continence recommendations between the groups. It was not possible to identify whether different types and "doses" of facilitation were influential within very diverse contextual conditions. The process evaluation (Rycroft-Malone et al., Implementation Science. doi: 10.1186/s13012-018-0811-0) revealed the models of facilitation used were limited in their ability to overcome the influence of contextual factors. © 2018 The Author(s).
