Interaction with the surrounding society and external stakeholders is an important component when developing and managing high quality and relevant education programs. This paper presents some of the outcomes of the project MERUT which was carried out during 2018 – 2020 with support from the Swedish innovation agency Vinnova. The key outcome is a toolbox offering a structured way to describe and handle methods and tools for stakeholder interaction. The methods of interaction are organized in three categories, denoted A, B, and C, where category A includes methods for external stakeholders to influence the management and development of the education program. Category B consists of means for external stakeholders to have an active role in course modules, and category C contains methods and tools to evaluate the quality and relevance of the education from, for example, alumni or employer perspective. Examples from the different categories are presented, including the CDIO Syllabus Survey, alumni surveys, and reflection documents. 

Supraphysiological loading induced by unstable orthopedic implants initiates osteoclast formation, which results in bone degradation. We aimed to investigate which mechanosensitive cells in the peri-implant environment produce osteoclast-stimulating factors and how the production of these factors is stimulated by supraphysiological loading. The release of osteoclast-stimulating factors by different types of isolated bone marrow-derived hematopoietic and mesenchymal stem cells from six osteoarthritic patients was analyzed after one hour of supraphysiological loading (3.0 ± 0.2 Pa, 1 Hz) by adding their conditioned medium to osteoclast precursors. Monocytes produced factors that enhanced osteoclastogenesis by 1.6 ± 0.07-fold and mesenchymal stem cells by 1.4 ± 0.07-fold. Medium from osteoprogenitors and pre-osteoblasts enhanced osteoclastogenesis by 1.3 ± 0.09-fold and 1.4 ± 0.03-fold, respectively, where medium from four patients elicited a response and two did not. Next generation sequencing analysis of osteoprogenitors revealed that genes encoding for inflammation-related pathways and cytoskeletal rearrangements were regulated differently between responders and non-responders. Our data suggest that released osteoclast-stimulating soluble factors by progenitor cells in the bone marrow after supraphysiological loading may be related to cytoskeletal arrangement in an inflammatory environment. This connection could be relevant to better understand the aseptic loosening process of orthopedic implants.

Betyder kvalitet och relevans samma sak inom högre utbildning? Medan begreppet kvalitet har studerats utförligt och används i utvärderings- och kvalitetssäkringssystem, är betydelsen och vikten av ordet relevans inte studerat i samma omfattning. Inom ramen för en nyligen genomförd studie gjordes ett försök att rama in begreppen kvalitet och relevans inom högre utbildning och klargöra eventuella likheter och skillnader i begreppens innebörd. Vidare belystes kopplingen till nyttiggörande och arbetsmarknad. Samtliga tillfrågade i studien såg kopplingar mellan kvalitet och relevans, och flera menade att en utbildning med hög kvalitet rimligtvis bör vara relevant, och av det följer att relevans bör vara en viktig komponent i kvalitetsbegreppet. Dessutom uppfattas kvalitet och relevans i många fall som delmängder av varandra, d.v.s. som kompletterande snarare än som motsatser. De tillfrågande såg ett tydligt samband mellan relevans och arbetsmarknad, men sambandet var inte lika starkt för begreppet kvalitet. 

Introduction 

Higher education institutions (HEIs) face challenges assessing the relevance of educational programmes. Upon graduation, the student should have acquired knowledge and understanding, competence and skills as well as good judgement and approaches to operate in a changing labour market. Ideas on new programmes and courses mainly emanate from research findings identified at the HEIs. Needs and expectations from external stakeholders have the potential to further contribute if room for collaboration is created. Extensive rapid societal changes increase this need for collaboration. 

The Standards and Guidelines for Quality Assurance in the European Higher Education Area (ESG) state that higher education aims to fulfil multiple purposes, including preparing students for active citizenship, future careers, personal development and create a broad, advanced knowledge base and stimulate research and innovation (ENQA, 2015). However, different stakeholders may have other priorities. Therefore, quality assurance needs to take these different perspectives into account. 

Relevance is considered an aspect of quality in higher education, but many HEIs in Sweden lack structures, processes, and methods for assessing relevance and involving stakeholders in these processes.

This project aimed to increase the knowledge and provide methods to systematically assess relevance and use university-industry collaborations as tools for educational development. 

Methods/Approach 

This paper is a summary of the project MERUT focused on methods for assessment of relevance in higher education. The project was carried out during 2017-2020 with financial support from Vinnova (The Swedish Innovation Agency) and involved seven Swedish HEIs. The connection to future career paths is often stated as the primary factor to describe the relevance of educational programmes and was selected as the focus of MERUT. Data have been collected using workshops, meetings, literature reviews, interview studies, and surveys. Important parts of the work have been interviews with external stakeholders in different labour-market areas who, in various ways, are involved in higher education, most often in advisory boards. Also, interviews with quality coordinators at university programmes as well as at faculty and university management levels at each HEI have been carried out.

The seven participating Swedish universities in MERUT have been Karolinska Institutet, Kristianstad University, KTH Royal Institute of Technology, Mälardalen University, Linköping University, Stockholm University, and Umeå University.

Results The project resulted in knowledge, tools, and methods to work systematically with relevance in higher education. The results can be summarized as follows:

·         Interviews with HEIs showed that they collaborate with external stakeholders in many ways, primarily around teaching and learning and to a lesser extent around programme management and quality assurance. 

·         Further, the involvement of stakeholders varied both between and within the universities (faculties, subject areas, levels of education). Therefore, it is difficult to evaluate, in a systematic way, how collaboration is included in the quality systems of the HEIs. 

·         A toolbox with methods for how to involve external stakeholders in the process of assessing and developing the relevance of a study programme. These methods can be used in continuous quality work, in major curriculum revisions as well as in the establishment of new programmes.

·         A checklist for external stakeholders' involvement in educational development to facilitate and clarify roles, structures, and tasks in connection with external stakeholders in both the development and operational phases of a study programme. 

The results show that there are many similarities between the HEIs in the study in terms of relevance assessment and dimensioning decisions. However, the potential of a systematic collaboration with stakeholders and society for relevance assessment and dimensioning of education is not yet fully being realised. 

Conclusion 

HEIs interact with external stakeholders in many ways within education. However, it is rare to find examples where external stakeholders are involved in the quality assurance process, at least not in a systematic way. The MERUT project has developed recommendations for collaboration perspectives and stakeholder participation in the governing of educational programmes. A systematic dialogue and interaction with stakeholders contribute to a mutual understanding of different stakeholder groups’ needs and expectations, and their view of quality of higher education. Furthermore, to consider relevance as a quality aspect creates a basis for a more methodical assessment process where external stakeholders can contribute in a clear role. MERUT has developed a toolbox and a checklist to facilitate such systematic interaction and collaboration with stakeholder groups. A conclusion of  this project is that a reciprocal, transparent, and systematic approach leads to a sustainable educational collaboration with improved quality and relevance of higher education.

It would constitute a large gain for society if the HEIs are able to systematically and by efficient processes take external stakeholders’ and societal needs and expectations into account when building comprehensive and systematic relevance assessment processes and in dimensioning of education.

This article provides an external stakeholder perspective on the influence of higher education in Sweden, exploring their views on curriculum development and qualitywork at the programme level. Semi-structured interviews with a selected number of representatives of external stakeholders involved in various educational areas were conducted at seven higher education institutions. The participants argued that changes intheir business sectors, and subsequent changes in the knowledge and skills in the labour needed, should encourage higher education institutions to adjust and develop their programmes. They did not anticipate or demand immediate changes in response to their comments, nor did they see themselves as a part of any quality assurance scheme. Uncertainties about the internal decision-making process and organisation in higher education institutions apparently do not facilitate external stakeholders’ understanding of their role in the larger scheme. However, all informants had comments on quality in higher education, perceiving it predominantly as something connected to the world of work. The practical implication of this study is that curriculum development at higher education institutions would benefit from communicating the internal decision-making processes to external stakeholders and agreeing on the expectations with them, in collaboration.

Background and purpose - Insufficient initial fixation or early micromotion of an implant is associated with a thin layer of fibrous tissue at the peri-implant interface. It is unknown if bone loss is induced by the fibrous tissue interface acting as an active biological membrane, or as a membrane that will produce supraphysiologic fluid flow conditions during gait, which activates the mechanosensitive osteocytes to mediate osteoclast differentiation. We investigated whether mechanically induced osteolysis is dependent on the fibrous tissue interface as a biologically active scaffold, or if it merely acts as a conduit for fluid flow, affecting the mechanosensitive osteocytes in the peri-prosthetic bone. Methods - Using a rat model of mechanically instability-induced aseptic loosening, we assessed whether the induction of osteoclast differentiation was dependent on the presence of a peri-implant fibrous interface. We analyzed the amount of osteoclast differentiation, osteocyte apoptosis, pro-resorptive cytokine expression and bone loss using immunohistochemistry, mRNA expression and micro-CT. Results - Osteoclast differentiation and bone loss were induced by mechanical instability but were not affected by the presence of the fibrous tissue membrane or associated with osteocyte apoptosis. There was no increased mRNA expression of any of the cytokines in the fibrous tissue membrane compared with the peri-implant bone. Interpretation - Our data show that the fibrous tissue membrane in the interface plays a minor role in inducing bone loss. This indicates that the peri-implant bone adjacent to loose bone implants might play an important role for osteoclast differentiation.

Cyclin-dependent kinase 8 (CDK8) is a mediator complex-associated transcriptional regulator that acts depending on context and cell type. While primarily under investigation as potential cancer therapeutics, some inhibitors of CDK8-and its paralog CDK19-have been reported to affect the osteoblast lineage and bone formation. This study investigated the effects of two selective CDK8/19 inhibitors on osteoclastogenesis and osteoblasts in vitro, and further evaluated how local treatment with a CDK8/19 inhibitor affects cancellous bone healing in rats. CDK8/19 inhibitors did not alter the proliferation of neither mouse bone marrow-derived macrophages (BMMs) nor primary mouse osteoblasts. Receptor activator of nuclear factor κΒ (NF-κB) ligand (RANKL)-induced osteoclastogenesis from mouse BMMs was suppressed markedly by inhibition of CDK8/19, concomitant with reduced tartrate-resistant acid phosphatase (TRAP) activity and C-terminal telopeptide of type I collagen levels. This was accompanied by downregulation of PU.1, RANK, NF-κB, nuclear factor of activated T-cells 1 (NFATc1), dendritic cell-specific transmembrane protein (DC-STAMP), TRAP, and cathepsin K in RANKL-stimulated BMMs. Downregulating RANK and its downstream signaling in osteoclast precursors enforce CDK8/19 inhibitors as anticatabolic agents to impede excessive osteoclastogenesis. In mouse primary osteoblasts, CDK8/19 inhibition did not affect differentiation but enhanced osteoblast mineralization by promoting alkaline phosphatase activity and downregulating osteopontin, a negative regulator of mineralization. In rat tibiae, a CDK8/19 inhibitor administered locally promoted cancellous bone regeneration. Our data indicate that inhibitors of CDK8/19 have the potential to develop into therapeutics to restrict osteolysis and enhance bone regeneration.

The CDIO Syllabus survey has successfully been applied to the Bachelor’s and Master’s programs in Experimental and Medical Biosciences, within the Faculty of Medicine and Health Sciences at Linköping University, Sweden. The programs are and have been, subject to considerable redesign with strong influence from the CDIO framework. One of the main drivers for the redesign is a shift concerning the main job market after graduation, from an academic career to industry and healthcare. One of the steps in the development process has been to carry out a Syllabus survey based on an adapted version of the CDIO Syllabus. The survey was sent out to students and to various categories of professionals, and in total 87 responses were received. The adapted version of the Syllabus and the design, execution, and outcome of the survey is presented.

Wear debris particles released from prosthetic bearing surfaces and mechanical instability of implants are two main causes of periprosthetic osteolysis. While particle-induced loosening has been studied extensively, mechanisms through which mechanical factors lead to implant loosening have been less investigated. This study compares the transcriptional profiles associated with osteolysis in a rat model for aseptic loosening, induced by either mechanical instability or titanium particles. Rats were exposed to mechanical instability or titanium particles. After 15 min, 3, 48 or 120 h from start of the stimulation, gene expression changes in periprosthetic bone tissue was determined by microarray analysis. Microarray data were analyzed by PANTHER Gene List Analysis tool and Ingenuity Pathway Analysis (IPA). Both types of osteolytic stimulation led to gene regulation in comparison to unstimulated controls after 3, 48 or 120 h. However, when mechanical instability was compared to titanium particles, no gene showed a statistically significant difference (fold change = ± 1.5 and adjusted p-value = 0.05) at any time point. There was a remarkable similarity in numbers and functional classification of regulated genes. Pathway analysis showed several inflammatory pathways activated by both stimuli, including Acute Phase Response signaling, IL-6 signaling and Oncostatin M signaling. Quantitative PCR confirmed the changes in expression of key genes involved in osteolysis observed by global transcriptomics. Inflammatory mediators including interleukin (IL)-6, IL-1ß, chemokine (C-C motif) ligand (CCL)2, prostaglandin-endoperoxide synthase (Ptgs)2 and leukemia inhibitory factor (LIF) showed strong upregulation, as assessed by both microarray and qPCR. By investigating genome-wide expression changes we show that, despite the different nature of mechanical implant instability and titanium particles, osteolysis seems to be induced through similar biological and signaling pathways in this rat model for aseptic loosening. Pathways associated to the innate inflammatory response appear to be a major driver for osteolysis. Our findings implicate early restriction of inflammation to be critical to prevent or mitigate osteolysis and aseptic loosening of orthopedic implants.

Polypyrrole (PPy) is a conducting polymer that enables controlled drug release upon electrical stimulation. We characterized the biocompatibility of PPy with human primary osteoblasts, and the effect of dopants. We investigated the biocompatibility of PPy comprising various dopants, i.e. p-toluene sulfonate (PPy-pTS), chondroitin sulfate (PPy-CS), or dodecylbenzenesulfonate (PPy-DBS), with human primary osteoblasts. PPy-DBS showed the roughest appearance of all surfaces tested, and its wettability was similar to the gold-coated control. The average number of attached cells was 45% higher on PPy-DBS than on PPyCS or PPy-pTS, although gene expression of the proliferation marker Ki-67 was similar in osteoblasts on all surfaces tested. Osteoblasts seeded on PPy-DBS or gold showed similar vinculin attachment points, vinculin area per cell area, actin filament structure, and Ferets diameter, while cells seeded on PPY-CS or PPY-pTS showed disturbed focal adhesions and were enlarged with disorganized actin filaments. Osteoblasts grown on PPy-DBS or gold showed enhanced alkaline phosphatase activity and osteocalcin gene expression, but reduced osteopontin gene expression compared to cells grown on PPy-pTS and PPy-CS. In conclusion, PPy doped with DBS showed excellent biocompatibility, which resulted in maintaining focal adhesions, cell morphology, cell number, alkaline phosphatase activity, and osteocalcin gene expression. Taken together, conducting polymers doped with DBS are well tolerated by osteoblasts. Our results could provide a basis for the development of novel orthopedic or dental implants with controlled release of antibiotics and pharmaceutics that fight infections or focally enhance bone formation in a tightly controlled manner.
