Face Mask Sensor to Detect COVID-19
Our breath holds a multitude of biomarkers, including potentially those indicating the presence of SARS-CoV-2, the virus responsible for COVID-19. Those infected with the virus are prone to exhale proteases, enzymes that speed up the breakdown of proteins, related to the new virus. This has led researchers at University of California, San Diego to (Read more...)
Cooling Vest Helps COVID Clinicians with Heat Stress
Researchers from the Radboud University Medical Center in The Netherlands have trialed cooling vests, originally designed for elite athletes, in nursing staff who have to put in long shifts in COVID-19 wards wearing full personal protective equipment (PPE). While essential, the protective equipment can lead to significant discomfort in the form of (Read more...)
10 Second COVID Antibody Test on a Chip
Researchers at Carnegie Mellon University have developed a microfluidic chip that can provide rapid COVID-19 antibody tests. The electrochemical test can detect very low concentrations of antibodies in blood samples, and transmits the results to a smartphone. The test could help to measure patient responses to vaccines and determine if they have be (Read more...)
Strados RESP Monitors Lung Sounds, Now FDA Cleared
Strados Labs, a company based in Philadelphia, PA, but with R&D offices in Atlanta, GA, won FDA clearance to introduce its RESP system for monitoring lung sounds. The RESP device has already been employed in clinical trials to help monitor how various therapies, patient reports, and other vital signs correlate with changes in lung sounds. [&hel (Read more...)
Real-time ELISA for Continuous Blood Testing
Though blood tests are a routine part of clinical care and hospital labs are able to quantify a myriad biomarkers, the results only indicate measurements at certain points in time. Continuous monitoring is available for only a few analytes such as glucose and oxygen. Now researchers at Stanford University have created a device that can […]
BIOMONITOR IIIm Injectable Cardiac Monitor Can Now Look for Signs of Fever
BIOTRONIK won FDA clearance for the Vital Data Sensor, a body temperature component within the BIOMONITOR IIIm injectable cardiac monitor (ICM). The ICM is designed to help cardiologists detect and diagnose cardiac arrhythmias remotely, but thanks to the Vital Data Sensor the implant now has an additional role in monitoring for signs of fever. This (Read more...)
Sleep Apnea Testing at Home: Interview with Laurent Martinot, CEO of Sunrise
Obstructive sleep apnea is very common and is associated with a variety of serious health issues, such as cardiovascular disease and diabetes. Getting a proper diagnosis is hampered by the need for patients to visit a sleep clinic and undergo a polysomnography. This gold-standard test is complicated and requires specialized staff to interpret the r (Read more...)
Artificial Attachments for Immune Cells Help Kill Tumors
Though immune cells have the capabilities to kill cancer cells, they’re often thwarted by cancer’s ability to evade detection. Researchers at Pennsylvania State University have now developed engineered natural killer cells that have a much better ability to find and kill cancerous cells. “We explored a novel method to engineer nat (Read more...)
Smart Ring Monitors Body Temperature, May Spot COVID Fever Early
A team of researchers, including those at the University of California, San Francisco and University of California, San Diego, has tested the potential of a smart ring, that can collect health data, including temperature and heart rate, to detect fever associated with COVID-19. In a proof-of-concept study, the researchers showed that the ring, deve (Read more...)
Radiotherapy to Prevent Recurrence Post Brain Tumor Excision: Interview with Matthew Likens, President and CEO of GT Medical
GT Medical Technologies, a company based in Arizona, has developed the FDA-approved GammaTile system, which can provide localized radiation therapy for brain tumor excision sites. Its goal is to reduce tumor recurrence and enhance patient survival. The treatment consists of radiation seeds encased in a collagen substrate. These are easy to place at (Read more...)
Saliva COVID Test Uses Smartphone for Results in 15 Minutes
Scientists at Tulane University have reported a new COVID-19 saliva test that uses a smartphone to provide results in as little as 15 minutes. Similar to technology from UC Berkeley that we reported on last week, the new test uses CRISPR technology and does not involve polymerase chain reaction (PCR) that, though accurate, is slow […]
Siemens epoc NXS Host Mobile Computer Cleared to Help Point of Care Blood Testing
Siemens Healthineers won both EU and US regulatory approval to introduce its epoc NXS Host mobile computer for the epoc Blood Analysis System. The Android smartphone provides an app-based intuitive interface that replaces the older interface that had over two dozen physical buttons and a relatively low resolution screen. The accompanying app is des (Read more...)
Mitochondrial Transplantation to Treat Ischemia-Reperfusion Injury: Interview with Dr. Alexander Schueller, CEO of cellvie
cellvie, a company based in Houston, Texas, is developing a mitochondrial transplantation therapy to help reduce the damage caused by ischemia-reperfusion injury. The treatment involves delivering isolated mitochondria to cells that are affected by ischemia to help mitigate the dysfunctional metabolism that contributes to cell death in that context (Read more...)
First Dedicated Pediatric and Neonatal Acute Dialysis Machine Released U.S.
Medtronic is releasing in the United States the industry’s first and only dedicated pediatric and neonatal acute dialysis machine. The Carpediem (Cardio-Renal Pediatric Dialysis Emergency Machine) has been in development for about a decade and the first in-human use was announced back in 2014. Having now received FDA marketing authorization, (Read more...)
Microbubbles Deliver Drugs Directly to Tumors
When fighting cancerous tumors, all too often the very drugs that can destroy a lesion tend to have significant negative effects on the rest of the body. Doses have to be maintained at moderate levels to avoid side-effects that are even worse than the disease. In light of this, researchers have been trying to develop […]
“VRx”: A Medgadget Book Interview with Author Dr. Brennan Spiegel
In the recently released science-fiction novel Ready Player Two, protagonist Wade Watts spends the majority of the book inside a virtual reality universe called the “OASIS”. Though the OASIS is merely a simulation consisting of computer-generated imagery, immersive sound, and gesture-based interaction, it has a profound impact on realit (Read more...)
