Considering patients as consumers could potentially be harmful

There is broad support for building health care systems that are patient centered, seen as a means of improving health outcomes and as morally worthy in itself. But the concept of patient-centered care has increasingly merged with the concept of patients as consumers, which "is conceptually confused and potentially harmful," write Michael K. Gusmano, a Hastings Center research scholar and an associate professor at Rutgers University; Karen J. Maschke, a Hastings Center research scholar; and Hastings Center president Mildred Z. Solomon in an article in the March 2019 issue of Health Affairs.

Researchers discover mechanism for how male sex steroids sculpt brain development

Researchers at the University of Maryland School of Medicine have discovered a mechanism for how androgens -- male sex steroids -- sculpt brain development. The research, conducted by Margaret M. McCarthy, Ph.D., who Chairs the Department of Pharmacology, could ultimately help researchers understand behavioral development differences between males and females.
