Most patients with Alzheimer's disease and Alzheimer's Disease Related Dementias (ADRD) experience the gradual onset and progression of cognitive symptoms, leading to decline over years or decades. However, in a small subset of patients, symptoms begin rapidly, leading to dementia within one year and complete incapacitation within two years of symptom onset. A new study at Mayo Clinic aims to determine why patients with Alzheimer’s disease and ADRD develop this rapidly progressive dementia (RPD).

Blood loss is the leading cause of death in trauma patients between the ages of 1 and 46 years, largely because they cannot access safe blood sources quickly enough. A possible solution? Freeze-dried synthetic blood. A multi-institutional team led by Dipanjan Pan, the Dorothy Foehr Huck & J. Lloyd Chair Professor in Nanomedicine at Penn State, recently received a five-year, $2.7 million grant from the National Institutes of Health’s National Heart, Lung, and Blood Institute to develop the next generation of synthetic blood.

Researchers from the GenX Exposure Study have detected PFAS (per- and polyfluoroalkyl substances) associated with a nearby fluorochemical plant in the household dust of homes located in Cumberland and Bladen counties, North Carolina. Homes closer to the plant had higher concentrations of those specific PFAS than homes located farther away.
