E-Cigarettes Not a Safe Alternative
Using a new low-cost, 3-D-printed testing device, UConn researchers found that e-cigarettes loaded with a nicotine-based liquid are potentially as harmful as unfiltered cigarettes when it comes to causing DNA damage. The researchers also found that vapor from non-nicotine e-cigarettes caused as much potentially cancer-causing DNA damage as filtered cigarettes, possibly due to the many chemical additives present in e-cigarette vapors. Several factors impact the amount of DNA damage e-cigarettes cause, says Karteek Kadimisetty, a postdoctoral researcher in UConn’s chemistry department and the study’s lead author. “I never expected the DNA damage from e-cigarettes to be equal to tobacco cigarettes,” says Kadimisetty. “I ran the controls again. I even diluted the samples. But the trend was still there — something in the e-cigarettes was definitely causing damage to the DNA.” The findings appear in the journal ACS Sensors.
New Device Tests Heart Health
UConn researchers from the Department of Mechanical Engineering have developed a device that can test blood viscosity during a routine office visit. The heart must work harder to pump sticky — high viscosity — blood, and studies have shown thicker blood can indicate cardiac event and stroke risk. UConn associate professor of mechanical engineering George Lykotrafitis and doctoral candidate Kostyantyn Partola have filed a provisional patent on the small electronic device, which requires just a finger prick of blood, gives precise readings in minutes, and costs under $1,000. Currently, physicians must send large blood samples to off-site labs for analysis in a rheometer. “With this information, doctors can suggest simple lifestyle changes on the spot to prevent their patients from having a stroke or heart attack,” says Partola.
The Lack of Black Men in Medicine
Medical school matriculation rates for black males have failed to surpass those from 35 years ago, according to a recent UConn Health analysis of data from the Association of American Medical Colleges. African-American men make up just 2.8 percent of the applicants to medical school. Out of all African-American applicants, only 38 percent are men, and black males who are unsuccessful in their first application are less likely to reapply than their white counterparts, the researchers write in the Journal of Racial and Ethnic Health Disparities. “The absence of Black males in medical school represents an American crisis that threatens efforts to effectively address health disparities and excellence in clinical care,” wrote authors Dr. Cato T. Laurencin and Marsha Murray.
Lifting Spirits Doesn’t Require Many Reps
More physical activity is not necessarily better when it comes to improving your mood, especially if you spend most of your day sitting, UConn and Hartford Hospital researchers found in a recent study. The work, published in the Journal of Health Psychology, found that people who led sedentary lives and engaged in light or moderate activity showed the greatest improvement in overall sense of well-being. Further, the study found no positive or negative association between high-intensity physical activity and subjective well-being, contradicting a widely reported recent study that found high-intensity workouts significantly lowered some people’s sense of well-being.
