Ad Displays in Stores Boost Teen Vaping Rates: Canadian Study

Ad Displays in Stores Boost Teen Vaping Rates: Canadian StudyMONDAY, June 29, 2020 (HealthDay News) -- Canadian provinces that allow retail displays promoting e-cigarettes had nearly three times the teen vaping rate, a new study found. Until May 2018, e-cigarettes weren't widely available in Canada and it was illegal to advertise those containing nicotine. When the law changed, Quebec and Manitoba adopted their own restrictions, including bans on retail displays and ads for e-cigarettes and other tobacco products. Study author David Hammond, a professor of public health at the University of Waterloo in Ontario, said this situation set up a "unique natural experiment" for researchers as Canada went from ban to a more open market. "It allowed us to answer the hypothetical question: Would lifting the restrictions make a difference in teen...

Affection, at Least for Women, May Be Rooted in Genes

Affection, at Least for Women, May Be Rooted in GenesSUNDAY, June 28, 2020 (HealthDay News) -- Genetics play a major role in how affectionate women are, but the same does not hold true for men, new research shows. "When we measure people's tendency to be affectionate and to receive affection from other people, almost without exception we find that women score higher than men," said study leader Kory Floyd. He's a professor in the University of Arizona's department of communication, in the College of Social and Behavioral Sciences. For the new study, Floyd's team assessed differences in the levels of affection expressed by 464 pairs of adult twins, aged 19 to 84. About half were identical twins and half were fraternal twins. In women, genes explain 45% of variability in affectionate behavior, while environmental influences such as the...

An Expert`s Guide to Keeping Bad Dreams at BaySATURDAY, June 27, 2020 (HealthDay News) -- If you're having nightmares during these stressful times, rest easy: A sleep expert says it's to be expected. "Your experiences and interactions during the day can affect your dreams, and right now many of us are spending time watching the news or reading articles that are downright scary," said Jennifer Martin, a director of the American Academy of Sleep Medicine. "It's natural that the fears and stressors of daily life make their way into our dreams." This is called dream incorporation, and it occurs when your real-life experiences show up in your dreams, she explained in an academy news release. Martin added that changes in sleep patterns -- including fragmented sleep -- can make people sleep less soundly, which means they remember...

Promising Results Mean Coronavirus Vaccine Trial Could...

Promising Results Mean Coronavirus Vaccine Trial Could Start by AugustTHURSDAY, June 25, 2020 (HealthDay News) -- Animal studies of a potential COVID-19 vaccine have been so encouraging that researchers plan to speed up testing of the vaccine in humans. Initially, the next phase of the trial was expected to begin in September, but that start date has now been moved to August. Developed by researchers at the Duke-NUS Medical School in Singapore, the vaccine uses genetic material called messenger RNA to trigger an immune response in the body. Once injected, the vaccine prompts the body to make proteins like those of the actual virus. The body will then know what coronavirus-infected cells look like and can learn to fight them off. Most vaccines are purely preventive, but this vaccine may also be able to treat an active case of coronavirus, the...

'COVID Toe' Lesions Probably Not Caused by COVID-19, Studies Find

`COVID Toe` Lesions Probably Not Caused by COVID-19, Studies FindTHURSDAY, June 25, 2020 (HealthDay News) -- Two new studies strongly suggest that the so-called "COVID toe" lesions that have popped up among some Americans during the pandemic may not be caused by infection with the new coronavirus after all. Despite intensive testing over a wide time period, none of the 51 study patients afflicted with the reddened, tender toes came up positive for SARS-CoV-2, the virus that causes COVID-19. Instead, the simple fact that many people are spending weeks on end walking around barefoot at home might be the cause, the researchers suggested. The Spanish researchers behind one of the studies now theorize that "these skin lesions are not induced by the virus, but by the quarantine state itself." The team, led by Dr. Ignacio Torres-Navarro, a...
