DoD partners with Detect-Ion to develop Point-of-Care Breath Diagnostics for Early Detection of Infected Warfighters

The recent COVID-19 pandemic has highlighted the need to rapidly detect infected humans to intervene early before severe conditions develop and to mitigate the spread of infections across a larger population. The ideal diagnostics approach should be painless (non-invasive), rapid, cost-effective, accurate, and should be versatile to detect multiple infectious pathogens, in some cases pre-symptomatically (even before the symptoms are visible). This diagnostics capability when applied to United States Department of Defense (DoD) warfighters would ensure mission readiness in austere environments, where providing adequate medical personnel and/or traditional diagnostics labs can be challenging. With this vision, DoD’s DIU teamed up with DTRA and has awarded an Other Transaction (OT) contract to Detect-Ion to develop such a Point-of-Care (PoC) Breath Diagnostics.

Detect-Ion’s PoC Breath Diagnostics project called “CLARION”, leverages a disruptive chip-scale mass spectrometry technology originally developed via prior high-risk/high-gain IARPA and DARPA investments to detect trace chemical signatures in ambient air for strategic intelligence collection and early warning systems, respectively. “This is a classic example of dual use technology which we plan to adapt for human breath analysis,” said Dr. Ashish Chaudhary, Founder/CEO of Detect-Ion, and the principal investigator of the CLARION project. “Typical exhaled human breath contains nitrogen, oxygen, carbon dioxide, carbon monoxide, argon, etc., and high amounts of water vapor. In addition to those major components, it contains a complex mixture of 100s of trace-level volatile organic compounds (VOCs) in the parts-per-million to parts-per-trillion range. There’s credible science that demonstrates that relative concentrations of some of these VOCs can get perturbed due to a host’s response to a certain infection, and this approach has been successfully demonstrated in lab-scale studies to discriminate infected humans from a healthy population. Our objective in CLARION is to leverage this science to establish the relevant VOC biomarkers, adapt our portable sensor hardware for exhaled breath analysis, and apply machine learning/artificial intelligence detection algorithms to enable near-real-time PoC infection screening.

If successful, a single CLARION device could run up to 160 breath analyses per day, at a fraction of the cost of rapid PCR tests. This could potentially offer high-throughput screening of large populations in a variety of densely populated military and civilian settings, such as offshore deployed battalions, military installations, airports, shopping malls, hospitals, concerts, etc. The project is planned over three years and allows DoD to pursue follow-on production if the pilot project succeeds in addressing the program metrics.

Centinel Spine’s prodisc ® Continues to Change Lives After Over 30 Years and 250,000 Total Disc Replacement Implantations

The prodisc lumbar and cervical technologies will be highlighted by Centinel Spine at the upcoming 2023 annual EUROSPINE meeting and congress in Frankfurt, Germany (October 4-6, 2023). The prodisc technology portfolio now includes four cervical and two lumbar devices—5 approved by the FDA—and has been validated with a reported reoperation rate of less than 1%.

Amber Implants Announces Start of Clinical Trial with VCFix® Spinal System

This first-in-human clinical trial will assess the safety and effectiveness of the VCFix® Spinal System implant for patients suffering from vertebral compression fractures. The implant is provided with a user-friendly, single-use sterile surgical kit, ensuring perfect traceability and reducing the risk of infection. 

RaySearch Deepens Collaboration with P-Cure

The expanded collaboration will enable users of the P-Cure proton therapy system to use RayStation and RayCare in a seamlessly integrated environment. The P-Cure system is a gantry-less seated proton system, designed to fit within linac vaults, that has recently been cleared by the FDA. It is used clinically by the Hadassah Medical Center in Jerusalem – the only proton facility in the Middle East – to treat CNS, head and neck, thoracic and pancreatic malignancies.
