For the first time in Germany: Heart Center of the UMG uses new procedure for cardiac arrhythmias. The Optrell mapping catheter, which allows precise imaging of the heart, was used for the first time in Germany at the Heart Center of the University Medical Center Göttingen (UMG). The catheter measures the electrical activity and structure of the heart while it is in place and creates a kind of “map”. The areas in the heart that cause problems can thus be…
UChicago Medicine has become the first medical center in Illinois to implant the Revi neuromodulation device, an exciting new treatment option that could offer relief for patients with urinary urgency incontinence (UUI). “I am really happy that we can offer this innovative approach to all our patients and very proud to be at the real forefront of medicine as the first in the state to have done this surgery,” said urologist Ervin Kocjancic, MD, the surgeon who performed the procedure. UUI,…
… for Neurosensory Therapies. Researchers from the Fraunhofer Institute for Photonic Microsystems IPMS and the Max Planck Institute for Multidisciplinary Natural Sciences (MPI-NAT) have researched optical stimulators for future cochlear implants as part of the “NeurOpto” project (funded by the Fraunhofer-Max-Planck Cooperation Program: 601001). They will present tiny OLED-on-silicon-based probes for the first time at W3+ 2024 in Jena, on September 25 and 26, 2024, at booth No. C12. What is Optogenetics? Optogenetics is a method that uses light to…
In the treatment of cancer patients, irradiation can be adapted anew each day to the position of the tumour and conditions in the body. Researchers at the Paul Scherrer Institute PSI have now, for the first time, integrated such a workflow into everyday clinical practice in proton therapy – an important step in the individualisation of therapy. The study appeared yesterday in the scientific journal Physics in Medicine and Biology. Every day, our body is a little bit different. The…
Study on pulsed field ablation with promising results. An international study involving the Heart Center of the University Medical Center Göttingen (UMG) shows that pulsed field ablation is more effective, gentler and associated with fewer complications than other methods for treating atrial fibrillation. With the pulsed field method, the areas of the heart tissue responsible for the development of atrial fibrillation are specifically sclerosed by means of electrical impulses and not by heat or cold as with other methods. The…
The novel technique could be used to treat damaged tissue in a range of medical applications, including reconstructive and plastic surgeries. A technology most often used for medical imaging is being repurposed as a new tool for restoring blood flow in tissue damaged from disease, injury, and reconstructive surgery. Biomedical engineers at the University of Rochester are leveraging ultrasound waves to organize endothelial cells—the building blocks of blood vessels—into patterns that can promote the growth of new vessel networks within days. “We…
The European Union is funding a project to develop a new concept of information transmission for active implanted medical devices as part of its funding program Horizon. For the ERMES project, the European Union is providing more than 3.7 million euros over a funding period of 36 months as part of the highly competitive Horizon program – EIC (European Innovation Council) Pathfinder Open. The aim of the project is to develop a new concept of information transmission for Active Implantable…
Scientists collaborate to customise top-of-the-line microscopy method with AI to better understand glioblastoma brain tumours. Imagine building a traffic surveillance camera that could detect trouble-making cells speeding around in your brain before their cellular gang could commit ‘crimes’. Most importantly, this camera could catch some of the biggest interlopers of all – cancer cells. This ‘surveillance camera’ is no longer a figment of the imagination. Along the brain’s biggest superhighway of nerve fibres that connects the brain’s right and left…
A sweat-powered wearable has the potential to make continuous, personalized health monitoring as effortless as wearing a Band-Aid. Engineers at the University of California San Diego have developed an electronic finger wrap that monitors vital chemical levels—such as glucose, vitamins, and even drugs—present in the same fingertip sweat from which it derives its energy. The advance was published Sept. 3 in Nature Electronics by the research group of Joseph Wang, a professor in the Aiiso Yufeng Li Family Department of…
Converting brain activity to text on one extremely small integrated system. Researchers from EPFL have developed a next-generation miniaturized brain-machine interface capable of direct brain-to-text communication on tiny silicon chips. Brain-machine interfaces (BMIs) have emerged as a promising solution for restoring communication and control to individuals with severe motor impairments. Traditionally, these systems have been bulky, power-intensive, and limited in their practical applications. Researchers at EPFL have developed the first high-performance, Miniaturized Brain-Machine Interface (MiBMI), offering an extremely small, low-power, highly accurate, and versatile…
3D bioprinting with the body’s own cartilage cells. Sport can lead to injuries if not performed correctly, often affecting the cartilage in the joints. Untreated cartilage defects can lead to osteoarthritis at older age, for which there is currently no effective treatment. Personalized cartilage cell implants made by 3D printing should provide a remedy in future. Special printing inks containing the body’s own cartilage cells are being developed for this purpose. The four-year project at the Fraunhofer Institute for Applied…
The risk of early heart failure after heart transplantation is lower if the donor heart is stored in a so-called heart-in-a-box instead of in the usual cooler with ice. This is according to a study where researchers at the University of Gothenburg are now presenting the results. The established way of storing donated hearts before transplantation is to keep them at four degrees in potassium solution in a cooler with ice. Handling is a race against time, where matching, transportation…
A commercial artificial intelligence (AI) tool used off-label was effective at excluding pathology and had equal or lower rates of critical misses on chest X-ray than radiologists, according to a study published today in Radiology, a journal of the Radiological Society of North America (RSNA). Recent developments in AI have sparked a growing interest in computer-assisted diagnosis, partly motivated by the increasing workload faced by radiology departments, the global shortage of radiologists and the potential for burnout in the field….
NIH-funded University of Cincinnati researcher studying magnetic nanoparticle delivery. Just as a business needs an effective and reliable service to deliver its goods to customers, medications need an effective delivery system to get them to the specific area of the body where they can have an impact. The University of Cincinnati’s Daniel Sun, MD, has received a career development award of just more than $1 million from the National Institutes of Health’s National Institute on Deafness and Other Communication Disorders…
Enhanced two-photon microscopy method could reveal insights into neural dynamics and neurological diseases. Researchers have developed a new two-photon fluorescence microscope that captures high-speed images of neural activity at cellular resolution. By imaging much faster and with less harm to brain tissue than traditional two-photon microscopy, the new approach could provide a clearer view of how neurons communicate in real time, leading to new insights into brain function and neurological diseases. “Our new microscope is ideally suited for studying the…
An innovative combination of tissue simulation, an authoring tool for creating custom learning content, and special haptic arms will make this possible. The long and complex training of surgeons is intended to prepare them as best as possible for the successful performance of complex procedures such as bone operations. With the help of virtual reality (VR), it is possible to realistically depict surgical situations and test training with virtual patients free of risk. However, current methods still have their limits…
