A small sponge called the SymphNode, which can carry cancer drugs and be implanted next to a tumor, has been developed by researchers at UCLA. The device has been tested in mice models with melanoma and breast cancer and achieved reduced tumor size in 100% of treated melanoma subjects and 80% breast cancer subjects.
In this medical malpractice case, the plaintiffs claimed the defendants’ negligence led to a child suffering a brain injury. They retained two obstetricians to opine on the standard of care for nurses.
The story of how Mieczyslaw “Michel” Mirowski ended up in America where he conceived the idea of an implantable cardioverter-defibrillator (ICD) is almost as incredible as the invention itself.
Researchers at Johns Hopkins University have created a 3D-printed gelatin robot powered by temperature that they say could replace intravenous injections and pills to carry medicine directly to infections, blood clots or tumors and bypass healthy tissue, according to a study published in Science Robotics. “Our study shows how the manipulation of shape, dimensions and patterning of gels can tune morphology to embody a kind of intelligence for locomotion,” says Study Author David Gracias
Young people experiencing suicidal thoughts may not notice worsening symptoms, which drove researchers at Oregon Health and Science University to partner with Analog Devices to develop a smartwatch that would serve as an early detector. The watch will collect data such as heart rate variability, which has been shown to correlate with suicidal thoughts in teenagers, and users and their parents will document stressors, among other measures, to see if a biometric signal can indicate suicide risk.
A point risk score prediction model that can identify an individual’s risk of developing dementia at 13 years has been developed by researchers in China using diagnostic study data involving 444,695 individuals in the UK. The tool was able to determine 13-year risk for dementia with almost 100% accuracy for both men and women.
Biomedical devices, such as a drug delivery tool, staples and stents made out of aluminum that dissolve within minutes when exposed to eutectic gallium-indium were developed by a team led by a Mechanical Engineering Assistant Professor at MIT. Researchers noted that further studies are needed to verify the technique’s safety in human applications.
An algorithm that works with a built-in accelerometer in a smart watch to track a user’s gait quality, Watch Walk, has been developed by researchers at the University of New South Wales and Neuroscience Research Australia. The tool measures walking-related factors, such as stride length, cadence, posture and speed, which can aid in determining an individual’s risk of falling.
The FDA has released two final guidances related to medical device post-market surveillance and procedures for handling post-approval studies. The procedures guidance offers recommendations on PAS content and format as a condition of premarket approval, while the surveillance guidance explains the Agency’s interpretation of post-market surveillance orders for certain Class II or Class III devices according to section 522 of the Federal Food, Drug, and Cosmetic Act (FD&C Act).
The Echoes app, which turns a smartphone into a standard stethoscope when placed on a user’s skin, shows promise in monitoring the progress of heart conditions, a study shows. “The results have shown that non-medical users are able to record heart sounds in sufficiently good quality for further processing of the signals. We may be able to extract further features for diagnosis and monitoring purposes in future clinical studies,” said study Author Hongxing Luo.
