U.S. Gun Violence Rates Jumped 30% During PandemicFRIDAY, Oct. 22, 2021 (HealthDay News) -- Gun violence sky-rocketed by more than 30% across the United States during the first year of the COVID-19 pandemic.Almost 39,000 injuries and deaths nationwide involved a gun in the year starting in February 2019 — and that number shot up to more than 51,000 between March 2020 and March 2021, according to nationwide figures compiled by the non-profit group, Gun Violence Archive (GVA)."We were not surprised that the gun violence rates were higher during the pandemic," said study leader Dr. Paddy Ssentongo. He is an assistant professor with the Center for Neural Engineering at Pennsylvania State University. "But we were surprised by the large magnitude of the increase."And some states saw far steeper inclines than others.While the rate of gun...

AHA News: Eating the Right Insects Can Provide Nutrition … And Might Be Good for the PlanetFRIDAY, Oct. 22, 2021 (American Heart Association News) -- The notion of biting into a bug or chewing on a cricket might make some people a bit squeamish.Don't squash the idea until giving this food some thought.Some 2 billion people around the world already eat insects to supplement their diet, according to the United Nations' Food and Agriculture Organization. The practice is known as entomophagy. Consuming the right critters can help address the pressing issues of food security with the world's population expected to grow to 9.8 billion by 2050, the UN says. Insects can provide nutrition, with high protein, fat and mineral contents.But it's not just about food scarcity. Insects are a staple in diets in parts of Asia, Africa and Latin America, and are consumed because of their taste,...

Deadly Liver Disease Tied to Obesity Is on the Rise

Deadly Liver Disease Tied to Obesity Is on the RiseFRIDAY, Oct. 22, 2021 (HealthDay News) -- Liver disease is usually associated with alcoholism or hepatitis, but obesity and diabetes are becoming an even more dire threat for potentially fatal liver damage, a new study reveals.In fact, advanced fatty liver disease increases a person's risk of death by nearly sevenfold, according to a new report.But it's a silent killer — by the time you develop symptoms related to fatty liver damage, you're in deep trouble, warned co-researcher Dr. Jeanne Clark, director of general internal medicine at Johns Hopkins School of Medicine, in Baltimore, Md."Once you got this advanced liver disease, which can take years and decades to develop, then people who had that scarring that got so advanced were more likely to die," Clark said.The condition occurs...

Scientists Develop Quick Test for Marijuana Use

Scientists Develop Quick Test for Marijuana UseFRIDAY, Oct. 22, 2021 (HealthDay News) -- Researchers may be one step closer to developing the equivalent of a Breathalyzer for detecting marijuana use.In an early study, scientists found that their rapid test was able to reliably detect THC in people's saliva in under 5 minutes. THC, short for tetrahydrocannabinol, is the active ingredient in marijuana.Right now, the "gold standard" for detecting marijuana use is to measure THC in the blood or urine. But those tests can take days to process. The other drawback is that unlike alcohol, THC can linger in the bloodstream for days or even weeks -- so a "positive" blood test does not necessarily reflect recent use.Those facts have made it hard to develop a roadside test for marijuana use, akin to the Breathalyzer used to measure drivers'...

Delta Variant Subtype on Rise in U.K.

Delta Variant Subtype on Rise in U.K.FRIDAY, Oct. 22, 2021 (HealthDay News) -- A subtype of the Delta variant is causing a growing number of infections in the United Kingdom and is being closely monitored there and in other countries.During the week of Sept. 27, the AY.4.2 variant accounted for about 6% of cases in the U.K. and is "on an increasing trajectory," according to the U.K. Health Security Agency, CNN reported.Despite its spread in the U.K., officials there have not yet classified it as a variant of concern.While some experts have suggested that AY.4.2 may be somewhat more transmissible than the original Delta variant, that has yet to be confirmed."As AY.4.2 is still at fairly low frequency, a 10% increase in its transmissibility could have caused only a small number of additional cases. As such, it hasn't been...

Just 5 Hours of Moderate Exercise a Week Cuts Your Cancer Risk

Just 5 Hours of Moderate Exercise a Week Cuts Your Cancer RiskFRIDAY, Oct. 22, 2021 (HealthDay News) -- Just a few hours a week of moderate exercise may reduce your risk of cancer, a new study suggests.If Americans got the recommended five hours a week of moderate-intensity physical activity, more than 46,000 cancer cases could be prevented in the United States each year, according to the report. The study authors said that 3% of all cancer cases in U.S. adults aged 30 and older from 2013 to 2016 were attributable to inactivity. More inactivity-related cancer cases occurred in women (almost 33,000) than in men (nearly 14,300) each year.Are these folks lazy? Not necessarily. Many Americans face barriers to physical activity, the researchers said, including: lack of time due to long hours in low-wage jobs; the cost of gym memberships or personal...

"It's critical to better understand how these mood disorders increase the likelihood of cesarean section deliveries, which we know have both short and long-term...
