Diagnostics World | Scientists and clinicians have been looking for behavioral predictors of suicide for decades now, and yet the most reliable detection method remains self-disclosure by individuals who feel life is not worth living. The work of trying to understand the brain mechanisms behind suicide is a newer, “burgeoning bubble” of research to better foresee who is in peril of taking their own life.

Diagnostics World | A team of researchers from the U.S. and China have developed a flat, adhesive wearable sensor for detecting signals of individual and population health through the skin, and it can be manufactured at low cost using components that are readily available pretty much anywhere. Initially used in “smart diapers” to detect wetness, the multifunctional device platform now has a superhydrophobic coating making it waterproof so it can accurately monitor health variables without moisture or humidity interfering with the sensing.

Diagnostics World | A technique for isolating urinary extracellular vesicles (EVs) released by cells across the body has enabled the discovery of previously undetectable biomarkers for Parkinson’s disease (PD) in the protein cargo of the nanoparticles. EVtrap—short for extracellular vesicles total recovery and purification—is now the foundation of Purdue University spinoff Tymora Analytical Operations.

Diagnostics World | Researchers at the University of Illinois Urbana-Champaign believe they have come up with an attractive approach to the battle against bacteria that can infect orthopedic implants—as well as the surfaces people encounter in everyday life, including smartphone screens and kitchen countertops. The smart surgical implant coating contains no chemicals but was instead inspired by the wings of cicadas and dragonflies that are naturally antibacterial through physical interactions.

Diagnostics World | A new antimicrobial susceptibility testing (AST) method developed by scientists at the University of California, Santa Barbara, resolves the longstanding conflict between what the gold-standard assay says will work and actual patient outcomes when it comes to selecting antibiotics. The alternative AST protocol reveals that antibiotics already widely available on the market can cure superbugs.

Diagnostics World News | In a first-of-its-kind, blinded and randomized clinical trial of artificial intelligence (AI) in cardiology, investigators at Cedars-Sinai Medical Center have shown that an “AI assistant” for assessing heart health works even better than sonographers at reading echocardiograms. The software was integrated with the institution’s picture archiving and communication system that securely stores and digitally transmits electronic images.

Diagnostics World | Researchers in Sweden who previously introduced a hydrogel wound dressing constructed of nanocellulose that requires no changing have further improved on their innovation with the integration of a pH sensor to passively monitor for early signs of infection. In parallel, they’re working on antimicrobial substances based on lipopeptides that are showing potency against multiple types of bacteria.

Diagnostics World News | Researchers at Pennsylvania State University are leading the development of a lateral flow assay for mpox (monkeypox), which in another few years could join pregnancy tests on retail pharmacy shelves. The more immediate plan is to produce a rapid, point-of-care (POC) test for low-resource settings that involves a smartphone or other small reader capable of differentiating mpox from smallpox based on the light bouncing back from gold nanoparticles underpinning the platform.

Diagnostics World | An international team of researchers has found that gut microbes can help diagnose gestational diabetes mellitus (GDM) as early as the first trimester of pregnancy, months earlier than is happening currently. The long-term aim of the group is to predict and prevent one of the most common pregnancy-related medical complications with adverse health implications for mother and child.

Diagnostics World News | Post-traumatic stress disorder is difficult to diagnose under the best of conditions, including knowing the triggering issues and how an individual responds to stressful events. For the mostly young and “macho” men in the military who are exposed to combat and separated from their families for many months at a stretch the obstacles—and stakes—are even higher.
