Teens with behavioral problems are more likely than others to use marijuana -- but the drug itself doesn't increase conduct problems, a new study indicates. The findings suggest that a "cascading chain of events" predict marijuana use problems as teens become young adults, according to the University of Pennsylvania researchers. "Cannabis use in and of itself does not appear to lead to conduct problems or increasing attraction to peers who use cannabis," said study co-author Dan Romer, a … [Read more...]
Women reluctant to take preventive breast cancer drug
Many British women won't take a drug that could prevent the development breast cancer over side effects concerns, a study says. Researchers from the University of Leeds in the UKpublished the findings Monday in the journal Clinical Breast Cancer. "Women in our study were rightfully considering the potential harms and benefits of using preventive therapy," Samuel Smith, a researcher at the University of Leeds and lead author of the study, said in a press release. "But some beliefs about the … [Read more...]
20 years after settlement, billions in anti-tobacco funds spent elsewhere
Twenty years after 46 states and the District of Columbia reached a historic settlement with four major tobacco companies, the United States has seen an unprecedented drop in adult smoking. But advocates say the billions paid to states are not always being targeted for smoking cessation. The 1998 agreement established a fund in which tobacco companies -- Philip Morris, R.J. Reynolds, Brown & Williamson and Lorillard, as well as industry trade associations -- pay states billions annually … [Read more...]
Opting for organic foods may reduce risk for some cancers
Paying extra for those pricey organic fruits and vegetables might pay off: New research suggests eating them might help you dodge a cancer diagnosis. People who consumed the most organic foods had a 25 percent lower cancer risk compared with those who ate the least, the study found. Specifically, eating more organically grown foods was linked to a 34 percent reduced risk of postmenopausal breast cancer, a 76 percent decreased risk for all lymphomas and an 86 percent reduced risk for … [Read more...]
Experimental vaccine may reduce risk of post-stroke blood clot
An experimental vaccine reduced the risk of post-stroke blood clot risk in a study with mice, researchers report in a new study. Researchers in Japan hope the vaccine, called S100A9, may one day replace oral blood thinners, which are used to help prevent another stroke. The findings were published Monday in the journal Hypertension. In addition, they found that the vaccine also doesn't increase the risk of serious bleeding or lead to an autoimmune response. "Many stroke patients don't … [Read more...]
Bug behind stomach cancer also linked to colon cancer
The same type of bacteria that causes stomach cancer may also increase colon cancer risk, especially in black Americans, a new study finds. Researchers analyzed data from more than 4,000 colon or rectal cancer cases in the United States. They found a significant association between rates of these cancers and infection with a virulent strain of H. pylori bacteria that's especially common among black Americans. The findings do not prove that H. pylori causes colon or rectal cancer, however. … [Read more...]
Squeezing pimples could make acne worse
It may be tempting to squeeze a large pimple, but doing so could make the zit worse, skin doctors say. Up to 50 million Americans struggle with various forms of acne, particularly red, swollen, painful bumps that develop deep in the skin, according to the American Academy of Dermatology. There are better, more effective ways to manage acne, said board-certified dermatologist Dr. Meghan Feely. "Although there are no overnight or immediate cures for acne, you don't have to stand by and … [Read more...]
Florence: Death toll rises, N.C. roads closed as more rain falls
Hurricane Florence has come and gone, but it will take time for the coastal Carolinas to recover from severe flooding and damage that has killed 18. Florence arrived early Friday as a Category 1 storm. Authorities said Monday the death toll climbed to 18. Most died in North Carolina from falling trees and other debris, and two in South Carolina died of carbon monoxide poisoning. The storm had weakened to a tropical depression, but still inundating the region with rain on Monday. The … [Read more...]
Study reveals new molecular properties of water
Scientists have discovered new molecular properties of water. Water is known as an efficient transporter of its autoionization components -- the charged particles, protons and hydroxide ions, created when an H2O molecule splits. Until recently, scientists assumed autoionization transportation occurred through a single mechanism, dictated by a single variable, the direction of the involved hydrogen bond. New theoretical modeling, however, showed the transportation mechanism features a … [Read more...]
Alcohol drives rise in liver disease deaths in young adults
The Great Recession continues to take a grim toll: Since 2009, a growing number of Americans have died from liver disease and liver cancer. The increase among 25- to 34-year-olds is especially troubling because the deaths are due to cirrhosis, a disease caused by excessive drinking, the authors of a new study said. The researchers suspect the economic downturn in 2008 prompted people to comfort themselves with alcohol. "These are deaths of despair," said lead researcher Dr. Elliot Tapper, … [Read more...]
