Diabetic foot ulcers (DFUs) often result in severely adverse outcomes, such as serious infections, hospitalization, and lower extremity amputations. In last few years, to improve the outcome of DFUs, clinicians and researchers put their attention on the application of low intensity pulsating electro-magnetic fields through Therapeutic Magnetic Resonance (TMR®). In our study, patients with DFUs have been divided into two groups: The Sham Group treated with non-functioning TMR® device, and the Active Group treated with a functioning device. Biopsies were recovered from ulcers before and after a 15-day treatment with both kind of TMR® device. To recognize signs of inflammation or healing process, the harvested biopsies were subjected to histological and molecular analyses. The histological analysis showed a change in cell population after treatment with TMR®: an increase of fibroblasts and endothelial cells with a reduction of inflammatory cells. After TMR® application, the gene expression profile analysis revealed an improvement in extracellular matrix components such as matrix metalloproteinases, collagens and integrins, a reduction in pro-inflammatory interleukins, and an increase in growth factors expression. In conclusion, our research has identified histological and molecular features of reduced inflammation and increased cell proliferation during the wound healing process in response to TMR® application.

PlumX Metrics

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
