The U.S. Centers for Medicare & Medicaid Services has proposed to terminate the coverage with evidence development requirement for the use of positron-emission tomography (PET) imaging for patients suspected of suffering from beta amyloids, a marker of Alzheimer’s disease (AD). However, CMS is also considering a removal of the coverage policy that limits each patient to a single PET scan per lifetime, although the proposal to allow Medicare administrative contractors (MACs) to determine coverage is drawing fire from industry and physician groups alike.

The composition of the skull bone is unique and plays a direct role in influencing brain health through small channels in the bone and immune cell expression pathways, reported researchers based at the Helmholtz Center and Ludwig-Maximilians University Munich.

The inter partes review (IPR) process used to adjudicate patent disputes in the U.S. has had its share of critics, but ongoing patent litigation revolving around nerve stimulation technology between Axonics Inc., and Medtronic plc has disclosed another bone of contention in how IPRs are handled. The Court of Appeals for the Federal Circuit has ruled that a patent holder, Dublin-based Medtronic in this instance, can offer a new claim construction for its disputed patent once an IPR has been instituted, but said also that the Patent Trial and Appeal Board (PTAB) had erred in not allowing Axonics to respond to the new claim construction, sending the related IPRs back to the PTAB for another look.

Rewalk Robotics Ltd. took strides to expand its portfolio—and achieve profitability—with an agreement to acquire Alterg Inc., a provider of anti-gravity systems for use in physical and neurological rehabilitation. Alterg uses NASA-derived differential air pressure (DAP) technology to reduce gravity’s effects on individuals with mobility challenges and pain. The $19 million deal is expected to close August 11, with additional cash earnouts tied to future revenue growth over the next two years.

In game-changing news for parents of children with cerebral palsy, researchers demonstrated significant clinical improvement in the sensorimotor function of children who underwent sessions using Spinex Inc.’s Spinal Cord Innovation in Pediatrics (Scip) therapy. With current treatment options limited to physical therapy, medication and/or surgery, Parag Gad, co-founder and CEO of Spinex, told BioWorld he believes that Scip therapy “can be the new standard of care” for children with cerebral palsy.

With more drugs for Alzheimer’s disease (AD) gaining FDA approval and an aging population at increased risk of dementia, the need for AD diagnostics is only going to grow. An estimated 6.7 million Americans live with Alzheimer’s today, with that number projected to hit 14 million by 2060, according to the CDC.

A research team from Leipzig University, the Max Planck Institute and Heidelberg University, all in Germany, devised a new segmentation algorithm for stroke lesions that improves upon previous methods. They used machine-learning models to effect CT image segmentation in the early stages of acute stroke. The research team published their findings on the fully convolutional graph network in July in the Journal of Medical Imaging.

The first participants are being treated in a clinical trial assessing a neuromodulation system developed by Magnus Medical Inc. to treat depression. The system employs the recently FDA-cleared Saint neuromodulation technology that saw remarkable results in a clinical trial for treating major depressive disorder (MDD). The new Open Label Optimization (OLO) clinical trial is evaluating the effectiveness of this platform in conjunction with the medtech’s Magnus Neuromodulation System.

Protein quality control research is “almost exclusively focused on heat shock proteins, which are ubiquitously present” up and down the evolutionary chain, Xiaolu Yang told BioWorld. But “for more sophisticated organisms, which we humans like to think we are, it’s a little odd that we still use the system that bacteria started with…. It seems like we should have something more. The TRIM system,” he added, “fills that gap.”

In good news for those who toss and turn in the night with restless legs syndrome and their bed partners, bioelectronic technology appears to reduce the disruptive and uncontrolled movement. Researchers claimed that the NTX100 tonic motor activation (TOMAC) therapy, developed by Noctrix Health Inc., has the potential to transform treatment for people with restless legs syndrome (RLS) who are resistant to medications.
