The combination therapy comprising carfilzomib, cyclophosphamide and dexamethasone (KCd) is effective, with a tolerable safety profile, in an Asian cohort with high-risk multiple myeloma (MM) — thus providing a more economical alternative as a potential upfront regimen in resource-limited settings, according to leading experts during a myeloma education webinar.

Computer and electrical engineers from The State University of New Jersey, US recently designed a cell counting platform that can be integrated with a wristband with readouts linkable to a mobile phone application.

The group created a portable and fully integrated system using LIA (lock-in amplification) method, a microfluidic biosensor, a microcontroller and a bluetooth module all compacted onto a flexible circuit board in the form of a wristband with smartphone readouts through an Android or Apple iOS application.

“Current wearables can measure only a handful of physical parameters, such as heart rate and exercise activity. The ability to monitor counts of different cells in our bloodstream would take personal health monitoring to the next level,” said study lead author Abbas Furniturewalla.

Flow cytometry is currently used for characterization and quantification of cells. However, this method is limited by collection of blood samples for every test run, and the need for a professional to operate bulky equipment and analyze data in the laboratory setting.
