A comprehensive nontargeted metabolomics analysis has revealed previously unknown classes of disease-linked metabolites in whole blood samples from dementia patients, which may have significant therapeutic implications for managing the untreatable common cognitive disorder.

The NIH and CDC granted researchers at the Feinstein Institutes for Medical Research at Northwell Health $700,000 to investigate an in-the-ear stimulator as a treatment for post-traumatic stress disorder (PTSD) in first responders to the attack on the World Trade Center 20 years ago. The researchers will enroll 30 World Trade Center first responders with chronic PTSD in a sham-controlled trial to test the effectiveness of a device that uses transcutaneous auricular stimulation of the vagus nerve, which has shown promise in preclinical studies.

TORONTO – Neupath Health Inc. and Cynergi Health Partners have signed a memorandum of understanding that could see Cynergi’s virtual reality (VR) software combined with Neupath’s remote pain management platform. The platform is expected to benefit from the therapeutic potential of Austin, Texas-based Cynergi’s Rilaxta VRx to lower patient anxiety and perception of pain as they walk through restful, VR-created landscapes. “We don’t see another group taking a similar, holistic approach to pain management that we are,” Neupath CEO Grant Connelly told BioWorld.

Vagus nerve stimulation (VNS) researchers notched another success with FDA approval of a drug-free rehabilitation system that uses the technology to help patients who have lost mobility in their hands and arms as a result of ischemic stroke regain function. Microtransponder Inc.’s Vivistim pairs rehabilitation exercises with VNS to enhance their impact. The clinical study evaluated by the FDA for the system's approval showed that Vivistim doubled the improvement in upper extremity motor function compared to supervised rehabilitative exercises alone at six weeks and 90 days.

Helius Medical Technologies Inc. has received an FDA breakthrough device designation for its Portable Neuromodulation Stimulator (Pons) device for temporary treatment of dynamic gait and balance deficits due to stroke.

TORONTO – Fluid Biotech Inc. has raised $4.7 million in oversubscribed seed funding to further develop and commercialize the world's first hybrid polymer-metal flow-diverting brain stent for curing brain aneurysms that can lead to stroke. Following successful preclinical studies of the stent, attention now turns to applying this fresh capital to hiring contract manufacturers to prepare for first-in-human implantation and production of the mostly polymer-constructed stent.

For most people, neither polyglutamine disorders nor neuromuscular disorders are likely to be among the things they associate with androgen receptor (AR) dysfunction. But the three are indeed linked. And researchers have reported new insights into the nature of those links that could lead to a treatment for spinal and bulbar muscular atrophy, and possibly other disorders linked to AR signaling dysfunction.

PERTH, Australia – Tali Digital Ltd. inked a licensing deal worth A$51 million (US$37.5 million) for its new digital therapeutic that could be the first line in early intervention to treat the underlying conditions of attention deficit disorders. Akili Interactive Labs Inc. will hold an ongoing license to Tali’s technology to become the exclusive commercialization partner for all pediatric cognition products in the U.S.

Opya Inc., a provider of integrated autism services, secured $15.4 million in a series A fundraising round. New investors in the round included Panoramic Ventures, Softbank’s Opportunity Fund, Disability Opportunity Fund, and Raven One Ventures. Divergent Investments and Altitude Ventures added to their existing investments in the company.

Researchers have shown that glucocorticoids, a type of steroid hormones, target both neuroplasticity-related genes and genes related to ciliary function in the brain. However, the effects on the different processes are mediated via different receptors, and in response to different stimuli. A study investigated the specific targets of glucocorticoids, giving new insights into the biological mechanisms of stress adaptations, and how they are linked to neural plasticity.
