A wearable fingertip patch could improve personalized care for people living with Parkinson’s disease by continuously tracking levels of Parkinson's medication through their sweat. The device operates using chemicals in this sweat — no batteries required. Its measurements were comparable to those obtained by standard laboratory blood tests.

As cigarette smoking reaches historic lows in the United States, new research from MUSC Hollings Cancer Center shows that many younger adults are replacing cigarettes with noncombustible nicotine products, particularly e-cigarettes, rather than quitting tobacco altogether. An analysis of national survey data found that while overall tobacco use has remained relatively stable, combustible tobacco use has declined sharply, especially among adults ages 18 to 34. Researchers also developed a new population harm-reduction index suggesting this shift could substantially reduce future tobacco-related cancers if it continues. However, the study found that older adults who smoke are far less likely to switch away from combustible tobacco, highlighting an important opportunity for tobacco cessation and harm-reduction efforts.
