Under pressure: Novel technology to model pressure-induced cellular injuries in the brain

Researchers at MUSC develop an ex vivo model of ICP-induced cellular injury to understand early cell-injury mechanisms and identify biomarkers associated with pathological pressure. The novel model successfully initiates cellular stress in a cell-specific manner, offering potential for therapies to minimize neurological deficits.

Most glaucoma patients don't ask about medication costs

A recent study found that less than one-third of glaucoma patients discuss medication costs with their doctor. High costs are a significant barrier to adherence, and doctors should consider discussing medication costs during visits to prompt a discussion. The study analyzed video recordings of 275 office visits and suggested further re...
