Screening for early signs of cognitive impairment and dementia amongst the elderly is a task that's often unevenly attended to by primary care physicians. But the routine personal consumer devices that we use every day might offer a clearer and more consistent window into early declines in cognitive and memory function, according to data from a feasibility study that were reported this week at the Association for Computing Machinery's Knowledge, Discovery and Data Mining conference in Anchorage, Alaska.

The Wyss Institute for Biologically Inspired Engineering at Harvard University works in a range of cutting-edge med-tech fields. Only a few years ago, it opted to incorporate one focus specifically on what it calls immuno-materials. The idea is to develop biomaterials that can concentrate or manipulate immune cells in order to identify new patient treatments while avoiding some of the systemic risks associated with drug-based immunotherapy.

Information technology and connectivity have transformed productivity and costs in nearly every industry. Health care, however, has remained persistently immune to this transmogrification. Electronic health records (EHRs) have been particularly disappointing on this front, with time-consuming and inconsistent physician data entry as well as poor integration across complex and emerging data sources from medical devices, imaging, genomics and wearables and, as a consequence, a lack of usefulness in improving population health analytics or personalized care.

It has been a few years since there was an active market for digital health IPOs. But that's changed now. Chronic health care management company Livongo Health Inc. has raised $355 million in an IPO, following last month's $609 million public debut for health care workflow management software company Change Healthcare Inc.
