The U.S. National Institutes of Health issued revised ethics regulations on Thursday with new rules on investments and consulting in the health industry that are aimed at cleaning up the agency’s image. The rules, some of which were softened after reviewing complaints, require certain top-level employees and their family members to get rid of investments that might be seen as affecting their judgment.They also prohibit employees from consulting for pharmaceutical, biotechnology or medical device manufacturing companies, health care providers or insurers, and research institutions that receive NIH grants.
