At the University of South Australia, researchers designed a system that allows them to measure a patient’s blood pressure with a camera. The camera visualizes the patient’s forehead and focuses on two regions in particular to optically determine photoplethysmographic signals that AI algorithms then convert to blood pressure data. The researchers tested their system in 25 volunteers, and so far it has proven to be approximately 90% as accurate as traditional pressure cuff measurements.

Coronary thrombosis is a dynamic process of platelet aggregation and subsequent coagulation. During spontaneous reperfusion -- whether via thrombolysis, or recruitment of collateral circulation -- there exists characteristic ST/T changes on the ECG.

I have often heard comparisons on the automation of System Status Management to the 2002 Spielberg movie starring Tom Cruise called “ Minority Report ” loosely based on the 1956 short story by Philip K. Dick. This science fiction action thriller is set in the year 2054 when police utilize a psychic technology to arrest and convict murderers before they commit their crime.
Researchers at the University of Pennsylvania have developed a microrobot system that can help with biofilm disruption, drug delivery, and sample retrieval, all within the restrictive space of the root canal. It can be difficult for dentists to know if they have removed all the infectious material when performing a root canal, and failure to do so will typically result in an infection reoccurring.
Enovis , a medtech company based in Delaware formerly known as DJO, recently announced the launch of ARVIS (Augmented Reality Visualization and Information System), an augmented reality technology that is designed to assist surgeons during implant placement in the hip and knee. The hands-free technology consists of an eyepiece that is mounted on a surgical helmet that provides the surgeon with real-time information about the position of an implant with respect to patient anatomy.
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.

In this Journal Jam podcast Anton and Justin welcome special guest Dr. Haley Cochrane. We dive deep into the evidence for timing of closure and infection rate, fluid choice, volume and pressure of irrigation of lacerations, glove type and infection rate, how eversion of wound edges effects cosmetic outcomes and much more. You might be surprised to discover that the evidence for many things we do for lacerations that are considered "standard of care", is either weak or non-existent.
