Delirium and Inflammation

July 30, 2015 10:25 am | by Harvard University | Comments

Delirium, an acute state of confusion, often affects older adults following surgery or serious illness. Now, a study confirms that inflammation—an immune response that develops when the body attempts to protect itself from harmful stimuli—plays a role in the onset of delirium.


New Computer-Based Technology May Lead to Improvements in Facial Transplantation

July 30, 2015 10:17 am | by Johns Hopkins University | Comments

Following several years of research and collaboration, physicians and engineers say they have developed a computer platform that provides rapid, real-time feedback before and during facial transplant surgery, which may someday improve face-jaw-teeth alignment between donor and recipient.


Hormone in Brain Could Cause Overeating, Says Rutgers Science

July 30, 2015 9:37 am | by Seth Augenstein, Digital Reporter | Comments

Eating for pure pleasure instead of hunger is controlled by a hormone in the brain, according to new Rutgers University research. The work could point to brain-first targets to combat the burgeoning obesity epidemic, according to the scientists.
