Researchers at the University of California San Diego created an ultrasound patch that can measure blood flow in vessels as deep as 14 cm within the body. The stretchy patch can be applied to the skin and may help clinicians to monitor and diagnose various conditions, including blockages that could cause an infarct. The patch contains an array of ultrasound transducers that can measure blood flow in vessels directly beneath it and the ultrasound beam can also be steered to assess vessels that are nearby, but not directly below. Monitoring...Read More
At the Houston Methodist Neurological Institute, researchers have developed a device that generates a magnetic field and used it to successfully shrink a glioblastoma tumor in a patient volunteer. The device is worn on the head each day during treatment, and uses an oscillating magnetic field to disrupt biochemical processes in cancer cells. While the technique is in its infancy, this first-in-human test of this particular type of device shows promise, and could herald the first steps in a new non-invasive treatment modality. Glioblastoma is a brain cancer with a...Read More
Researchers at Carnegie Mellon University, along with collaborators in the Netherlands, have developed a heart model consisting of engineered cardiac muscle tissue that is attached to an elastic material. The design allows the team to mimic the mechanical forces experienced by heart tissue in the body, which should provide them with more accurate data when using the model to replicate disease or study the effects of various treatments. The design may eventually lead to new ways of more accurately recreating heart muscle tissue in the lab, which could function as...Read More
Patients with head and neck cancer frequently require surgical removal of lymph nodes from the neck. While this is necessary, it can cause pain and stiffness that can persist for a long time after surgery. Assessing neck mobility of such patients would be useful, as it would allow doctors to identify deficits in range of motion, and design appropriate strategies to help improve them. However, current techniques to achieve this are somewhat crude and do not produce quantifiable data, or involve equipment that is not easily portable or easy to...Read More
Scientists at MIT have announced that they developed novel nanoparticles to detect cancer in urine samples. As well as detecting the presence of tumors, the nanoparticles can also accumulate at tumor sites and function as an imaging agent, helping to identify their location. These multifunctional particles could be very useful for routine cancer screening and helping clinicians to determine whether a tumor has spread or recurred. "This is a really broad sensor intended to respond to both primary tumors and their metastases,” said Sangeeta Bhatia, a researcher involved in the...Read More
100Plus, a California medtech company, created a suite of remote patient monitoring technologies. These include a digital weight scale, blood pressure cuff, thermometer, and blood glucose monitor. The company recently launched Ava, an AI powered healthcare assistant that is specifically intended for senior patients who may not be tech savvy or as open to new technologies. The system aims to personify staff at the local physician practice of the patient, which helps to build trust and rapport, with the aim of engaging patients within their own home. The ultimate goal...Read More

Researchers at the Technical University of Munich have developed a method to create tiny virus traps that can bind viral particles and render them harmless within the body. The technique relies on DNA origami to create self-assembling hollow nanocapsules, which are lined with molecules that will bind viruses and prevent them from leaving. With a viral pandemic currently running riot, such technologies should be very welcome for the future. Effective anti-viral drugs are elusive for many viral infections, COVID-19 being no exception. These researchers have developed a new type of...Read More
CloudCath, a medtech company based in San Francisco, has created the CloudCath system, a remote monitoring technology that provides clinicians with data on the spent dialysate fluid of at-home peritoneal dialysis patients. CloudCath is incorporated into the drain line of peritoneal dialysis systems, and wirelessly transmits data to the cloud, with proprietary algorithms then highlighting issues, such as infection, to clinicians. At present, abnormalities with peritoneal dialysis patients may not be flagged in a timely manner. For instance, patients are advised to check their dialysate using the "newspaper test," whereby...Read More
Researchers at Pohang University of Science & Technology in South Korea are reporting on having developed a technique for minimally invasive diagnosis of thyroid cancer. The method combines multispectral photoacoustic imaging and machine learning, and is conceived as a replacement for invasive and occasionally inaccurate fine-needle aspiration biopsies. The new technique involves analyzing the unique photoacoustic signatures of malignant thyroid nodules and then training the system to recognize them. The vast majority of thyroid nodules are benign, but as 5-10% are not, it is advisable to get them checked out....Read More
Researchers at the Harvard Wyss Institute have developed a biomaterial-based vaccine technology that could provide prophylactic protection against bacterial infection and septic shock. The technology is delivered as a biomaterial scaffold. Once inside the body, it captures bacterial pathogens and then recruits and activates dendritic cells to initiate a broad immune response against the pathogen of choice. So far, the technology has demonstrated protective efficacy against sepsis in animals. Bacterial infections, once largely controllable with antibiotics, are becoming a growing problem with the rise of bacterial resistance. Sepsis is a...Read More
Neurescue, a medtech company based in Denmark, created the NEURESCUE system, a balloon catheter designed to occlude the aorta, resulting in a significant increase in blood flow to the heart and brain. The mechanism is intended to provide emergency treatment for patients suffering a hemorrhage or cardiac arrest. Both hemorrhage and cardiac arrest represent unmet needs, resulting in a significant number of deaths each year. At present only one in ten people survive a cardiac arrest, illustrating the stark outcomes of this patient population. Aortic occlusion can help to control...Read More
