‘Living medicine’ could treat drug-resistant infections

Researchers at the Centre for Genomic Regulation (CRG) and Pulmobiotics S.L have created the first ‘living medicine’ to treat antibiotic-resistant bacteria growing on the surfaces of medical implants. The researchers created the treatment by removing a common bacteria’s ability to cause disease and repurposing it to attack harmful microbes instead.

Cemented hips help preventing infections

For decades, hip arthroplasty has been a routine procedure. In Europe, both total and partial hip replacements are the most frequent surgical interventions for patients with hip fracture or osteoarthritis. The treatment relieves pain and has good long-term outcomes. In cemented hip replacement, the artificial acetabulum and/or the femoral stem are fixed with bone cement and implant and bone bond…

Virtual training by hip implant simulator

Trainee trauma or orthopaedic surgeons have limited chances to practice hip replacement surgery before their first hands-on case. To change this, a team in the Dynamic HIPS project aim to improve this by creating a dynamic hip replacement simulator for future surgeons to practice the intervention and develop a reality-based feel for the procedure.

Researchers develop implantable AI system

Artificial intelligence (AI) will fundamentally change medicine and healthcare: Diagnostic patient data, e.g. from ECG, EEG or X-ray images, can be analyzed with the help of machine learning, so that diseases can be detected at a very early stage based on subtle changes. However, implanting AI within the human body is still a major technical challenge. TU Dresden scientists at the Chair of…

Shape-changing implants could help treat severe back pain

A team of engineers and clinicians has developed an ultra-thin, inflatable device that can be used to treat the most severe forms of pain without the need for invasive surgery. The device, developed by researchers at the University of Cambridge, uses a combination of soft robotic fabrication techniques, ultra-thin electronics and microfluidics.

New device to speed up bone healing

Researchers know that electricity can help speed up bone healing, but “zapping” fractures has never really caught on, since it requires surgically implanting and removing electrodes powered by an external source. Now, researchers at the University of Wisconsin–Madison have expanded on this principle and developed a device to speed up bone healing.

AI could improve speech recognition in hearing aids

In noisy environments, it is difficult for hearing aid or hearing implant users to understand their conversational partner because current audio processors still have difficulty focusing on specific sound sources. In a feasibility study, researchers from the Hearing Research Laboratory at the University of Bern and the Inselspital are now suggesting that artificial intelligence (AI) could solve…

A pacemaker that dissolves when it's no longer needed

Researchers at Northwestern and George Washington (GW) universities have developed the first-ever transient pacemaker — a wireless, battery-free, fully implantable pacing device that disappears after it’s no longer needed. The thin, flexible, lightweight device could be used in patients who need temporary pacing after cardiac surgery or while waiting for a permanent pacemaker. All components…
