A study led by researchers at Washington University School of Medicine in St. Louis concludes that as researchers turn to the internet to find study participants, current health-care disparities may persist. They found that getting individuals to go online was difficult, particularly if subjects didn't have high school educations, had incomes below the poverty line or were African-American.
A research project at the University of Illinois, funded by the National Institute on Drug Abuse, is examining the use of mindfulness therapy in preventing drug abuse relapse among marginalized young adults.
Rats' blood vessels took at least three times longer to recover function after only a minute of breathing secondhand marijuana smoke, compared to recovery after a minute of breathing secondhand tobacco smoke. With many states legalizing medical and recreational marijuana, and possible corporate expansion within the cannabis industry, this type of research is important to help understand the health consequences of exposure to secondhand marijuana smoke, researchers said.
Researchers studied the relationship between health insurance coverage and tobacco and alcohol use among reproductive age women in the US, and whether there were differences according to pregnancy status. The findings showed that pregnant women with insurance coverage had lower odds of alcohol use in the past month; however the odds of tobacco use were not affected. For non-pregnant women, insurance coverage resulted in higher odds of alcohol use but lower odds of using tobacco.
Two separate UCLA studies reveal that menopause -- and the insomnia that often accompanies it -- make women age faster. The dual findings suggest these factors could increase women's risk for aging-related diseases and earlier death.
Using direct neural recordings from the visual word form area, researchers were able to see words that patients read as the patients read them.
Researchers at Washington University School of Medicine in St. Louis have found how sensory nerve cells work together to transmit itch signals from the skin to the spinal cord, where neurons then carry those signals to the brain. Their discovery may explain why some people experience various types of itching, including chronic itching, and help scientists find ways to make some types of itching stop.
Researchers from Oxford and UT Austin suggest that while no gene 'causes' mental ill health, some genes can make people more sensitive to the effects of their environment -- for better and for worse -- leading to both mental ill health and enhanced mental resilience.
A modeling study by top tobacco control experts finds that e-cigarettes are likely to provide public health benefits based on 'conservative estimates' of the likely uptake of vaping and smoking by adolescents and young adults. 'Our study indicates that, considering a broad range of reasonable scenarios, e-cigarettes are likely to reduce cigarette smoking and not lead to offsetting increases in harm from the use of e-cigarettes and more deadly cigarettes,' says the lead author.
Regular cocaine and methamphetamine users can have difficulty choosing between right and wrong, perhaps because the specific parts of their brains used for moral processing and evaluating emotions are damaged by their prolonged drug habits. This is according to a study among prison inmates by Samantha Fede and Dr. Kent Kiehl's laboratory at the University of New Mexico and the nonprofit Mind Research Network. The findings are published in Springer's journal Psychopharmacology.
