Researchers at the University of Texas at Arlington, in collaboration with Shani Biotechnologies, a local firm, have created a point-of-care device that can accurately measure hemoglobin levels and perform pulse oximetry in individuals with dark skin. At present, methods to determine hemoglobin levels at the point of care, such as pulse oximetry, are inaccurate in individuals with higher levels of melanin in their skin, and there is a clear need to develop alternatives that work for everyone.
While most of us have a clear algorithm in our minds for the management of life-threatening hyperkalemia, the same may not be said about the other life-threatening electrolyte abnormalities. In this ECG Cases blog Dr. Jesse MacLaren gives us an approach to potassium, calcium and magnesium abnormalities including risk factor assessment, ECG interpretation and management pearls.

Researchers at the University of Arizona have developed a battery-free light-powered pacemaker that uses optogenetic stimulation of cardiomyocytes to achieve heart pacing. With conventional pacemakers, the leads of the device are anchored into the wall of the heart, using invasive hooks or screws. Small electrical shocks are then sent through the entire heart, potentially causing discomfort and pain.
Do not let a negative X-ray rule the day! Like almost all medical tests X-rays are far from perfect and should be ordered and interpreted only in the context of a thorough history and physical exam. In this 2nd part of our 2-part series on orthopedic x-rays with Dr. Arun Sayal and Dr. Yatin Chadha we discuss the pitfalls of obtaining and interpreting orthopedic X-rays, when orthopedic X-ray decision tools lead us astray, how understanding the concept of central ray helps dictate how we should or
Preceptis Medical , a medtech company based in Minnesota, created the Hummingbird Tympanostomy Tube System. The device allows ear, nose, and throat (ENT) surgeons to insert ear tubes in the comfort of their office. The procedure requires only local anesthetic and is intended to be less distressing for pediatric patients than the conventional approach, which requires general anesthesia.

Written by Pendell Meyers Family of an elderly woman with many comorbidities called EMS when she suddenly experienced shortness of breath, nausea, vomiting, and near syncope. She was alert and oriented and hypotensive with initial BP 70/50. A 12 lead ECG was obtained by EMS and is shown below: What do you think? There is sinus tachycardia (do not be fooled into thinking this is VT or another wide complex tachycardia!
By Kathryn Hockemeyer Peer Reviewed I caught up with a friend who works in environmental, social, and corporate governance investing during a lull in the COVID-19 pandemic. Seconds into the conversation, he asked, “I hear the.
Researchers at the University of Sydney in Australia have developed an electrospun blood vessel replacement. The material contains tropoelastin, a natural precursor for elastin, a key component of blood vessel walls. Elastin is present in concentric circles in natural blood vessels and provides the elastic properties which allow them to distend slightly and then reform their original shape in response to changes in blood flow and blood pressure.
I was shown this ECG; "Steve, what do you think of this?": What is going on? I said: "This is pulse tapping artifact and a long QT" Why did I say that? Whenever you see a very bizarre EKG, you should think about pulse tapping artifact. This is when one of the limb lead electrodes is placed over an artery, especially when placed over a dialysis fistula.
Researchers at the University of Washington have developed a low-cost hearing test for newborns. Traditionally, the equipment for such testing is quite expensive. As newborns cannot let us know if they can hear something, the test is based on creating a noise within the ear canal and then listening to the vibrations created by the specialized hair cells within.

Scientists at the University of Eastern Finland have developed a technique that lets them improve the coating of nanoparticles when using cell membranes. Cell membranes offer a lot of benefits as a coating for synthetic nanoparticles, including shielding from the immune system, prolonged circulation times and improved tumor accumulation. However, current approaches to coating nanoparticles with cell membranes often result in an incomplete covering.
Engineers at MIT have developed a system that could let users of robotic prostheses to more sensitively control their bionic limbs. The technology involves implanting pairs of small magnetic beads into muscles. When the muscles contract, the beads move closer together, allowing prosthetic devices to more precisely calculate a user’s intentions and mirror these.
Cordio Medical , a medtech company based in Israel, has developed HearO, an app that can assist in monitoring congestive heart failure. The technology is based on the phenomenon whereby congestive heart failure patients demonstrate changes in their voice as their disease progresses or in advance of disease exacerbation. This includes lung sounds, such as wheezing and crackling.
