Important funding received for a multidisciplinary clinical study on periprosthetic joint infections and antimicrobial resistance

Assoc Prof Margarita Trobos has recently obtained funding from ALF (500 000 SEK/year) and CARe (596 276 SEK) for the period 2020-2022, to carry out a clinical treatment research project that aims to validate a novel diagnostic method that can guide the treatment of periprosthetic joint infections (PJI).The departments of Biomaterials (GU), Orthopaedics (SU/Mölndal) and Infectious Diseases (SU/Östra) are collaborating in this study.

Key Publication Interview

Nadja Nänni in conversation with Christer Dahlin about his key publication on Guided Bone Regeneration.
Reference: Dahlin C, Sennerby L, Lekholm U, Linde A, Nyman S.: Generation of new bone around titanium implants using a membrane technique: an experimental study in rabbits. Int J Oral Maxillofac Implants. 1989 Spring;4(1):19-25.
The study by Christer Dahlin and his co-authors is a key-publication on Guided Bone Regeneration (GBR), that celebrates already its 30th anniversary in 2019. It describes the first time that a membrane was used with the aim of regenerating bone around implants by providing a secluded space for osteogenesis and to prevent soft-tissue ingrowth. Nadia Nänni talked to Christer Dahlin about this study during a congress in Bern in November 2019. Christer Dahlin explained how the idea for this study was developed, the implications it had, and he shared some personal insights and background information on his early career.

Xiaoqin Wang et al recently published in Biomaterials, “Exosomes influence the behavior of human mesenchymal stem cells on titanium surfaces”

Titanium is one of the most commonly used material for dental and orthopedic implants. Although the current titanium implants show high survival rate after 10-15 years, there is still a clinical need of novel implants especially for patients with deranged musculoskeletal tissues which exhibit poor regenerative potential. In a recent publication, “Exosomes influence the behavior of human mesenchymal stem cells on titanium surfaces” in the journal Biomaterials, by Xiaoqin Wang and co-workers, a novel strategy of surface modification for titanium implants via immobilization of exosomes, is presented.
Exosomes secreted from human mesenchymal stem cells (MSCs) have previously shown to possess both regenerative and immunomodulatory properties. Here, it is demonstrated that immobilization of exosomes on titanium surfaces dramatically accelerate MSC adhesion, spreading and proliferation. These observed effects of immobilized exosomes could be attributed to the presence of abundant cell adhesion molecules and signaling molecules in the MSC exosomal proteome. Given the importance of initial recruitment, adhesion and proliferation of fundamental cellular components, particularly MSCs, at titanium implant surfaces for successful bone regeneration around implants and osseointegration, the current findings suggest a biological approach for the generation of bioactive titanium implants.

Best Poster award vid den internationella kongressen Osseo 2019 i USA

“Effect of drill parameters on heat generation during osteotomy preparation for bone-anchored hearing systems” by Martin L. Johansson; Hanna Peters; Emelie Lager; Omar Omar, Department of Biomaterials in collaboration with Oticon Medical, was recently presented at 7th International Congress on Bone Conduction Hearing and Related Technologies (Osseo) in Miami Beach, USA, was rewarded Best poster in the category basic research.
The presentation was on the evaluation of a novel drill system, MIPS, for installing bone-anchored hearing aid system (BAHS). The vitro study evaluated the new drill system in terms of cutting performance and explored the role of the irrigation and drilling procedure on the degree of heat generation during drilling. The study demonstrated that the MIPS system is more efficient compared to the control system reflected in a lower drill force and torque. Moreover, the MIPS system was less sensitive to deviations from the recommended drilling procedure as demonstrated by a lower degree of heat generation when irrigation is impaired and the drilling sequence prolonged.

The Sahlgrenska Academy, University of Gothenburg is one of 7 partners in a recently granted 4-year research project on a novel treatment of osteoarthrosis.

APRICOT project kick-off at the University of Southampton, UK, 11-12 November, 2019

The project is coordinated by the University of Southampton, UK. The project was granted within the prestigious Horizon 2020 EU FET Open Program. The program is open to all disciplines, focussing on groundbreaking fundamental research, having high risk and a potential for a paradigm shift in the field. The successful grants awarded within the FET Open program range between 4% and 12% during the recent years.
