Anti-Vaxxers Mounting Internet Campaigns Against COVID-19 Shots

By | | Add a Comment

People who are hesitant about getting the COVID-19 vaccine don’t have to work hard to find internet rumors and theories that will fuel their fears regarding the vaccine’s safety. That’s because anti-vaccine groups and individuals are working overtime to promote frightening, false theories about the two COVID-19 vaccines that have now been administered to more than 24 million Americans, infectious disease experts say. “These kind of rumors have been around ever since Edward Jenner made his smallpox vaccine in the late 1700s,” said Dr. Paul Offit, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia. “There was a belief if you got the vaccine, which was derived from cowpox, that you would take on bovine characteristics. You’d get a snout, you’d get a tail, you’d get floppy ears. That was the internet 1802, basically.” There are two major types of disinformation being promulgated about the coronavirus vaccines: Anecdotal “cause-and-effect” rumors that erroneously tie a person’s untimely demise to the fact they recently got a COVID-19 vaccine. “Big lie” conspiracy theories that allege the vaccine can cause all manner of major side effects, from infertility to permanently altering your genetics. Health care workers had braced for stories coming out that tie people’s personal health problems and untimely deaths to their recent vaccination, even though there’s no evidence linking the two. For example, vaccine…  read on >  read on >

AHA News: 5 Things Nutrition Experts Want You to Know About New Federal Dietary Guidelines

By | | Add a Comment

FRIDAY, Jan. 29, 2021 (American Heart Association News) — New federal dietary guidelines encourage Americans to focus more on eating healthy throughout life, to be flexible in their eating patterns and to cut down on empty calories. The recommendations, released every five years by the U.S. Department of Agriculture and the Department of Health and Human Services, are designed to promote nutrition and prevent chronic disease. The guidance influences food and nutrition programs at the federal, state and local levels, and impacts how food companies formulate their products. “The high prevalence of diabetes, cancer and heart disease could be reduced if people ate better,” said Judith Wylie-Rosett, a professor of health promotion and nutrition research at the Albert Einstein College of Medicine in New York City. “Chronic diseases are often related to obesity and poor nutritional habits.” Here are five important takeaways from nutrition experts: There’s flexibility to customize The recommendations emphasize that healthy eating comes in many forms and can be adjusted to fit cultural traditions, personal tastes and different budgets. Swapping out red meat, for example, doesn’t mean people have to force down their least-favorite source of protein. “You can go with a plant-based diet or eat seafood, poultry and legumes rather than red meat,” said Penny Kris-Etherton, a distinguished professor of nutrition at Pennsylvania State University in University Park.

Lockdowns Might Not Have Long-Term Psychological Effect: Study

By | | Add a Comment

While pandemic lockdowns may have initially triggered feelings of isolation and worry, stay-at-home stress dissipated with time as people adjusted to their “new normal,” research suggests. In the study, scientists did a state-by-state analysis of Google search trends between January and June of 2020, covering topics such as COVID regulation policies, mental health concerns and in-home activities. On the “negative feelings” side of the ledger, search terms included “antidepressants” and “suicide.” More positive searches included “cooking” and “exercise tips.” Search trends were then stacked up against the varying timing and nature of each state’s particular lockdown experience. The result: “Google searches for mental health symptoms such as ‘isolation’ and ‘worry’ spiked after the implementation of the mitigation policies,” noted study author Bita Farkhad, an economist and a postdoctoral researcher in psychology at the University of Illinois Urbana-Champaign. But after two to four weeks, those spikes fell. In fact, Farkhad and her colleagues found that Google searches for terms that might indicate serious mental health issues — such as “suicide,” “antidepressant” and/or antidepressant drug names (Xanax, Prozac, Zoloft) — actually tended to drop off following the launch of stay-at-home orders. Why? The team theorized that not everything revolving around stay-at-home orders is by definition negative. For example, lockdowns also afford some with a rare opportunity to spend more time with loved ones, or to develop new,…  read on >  read on >

Is There a ‘Risk-Taking’ Center in the Brain?

By | | Add a Comment

Why does one person take a lot of risks and another proceed with more caution? Researchers came closer to that answer with a new study that shows risk-taking behavior may be related to characteristics in the brain. The study found there is no one risk area in the brain. Instead, there are many regions where anatomy is altered in people who take risks. Yet there is a connection between genes, lower levels of gray matter and risky behavior, researchers concluded. “People have different tendencies to engage in behavior that risks their health or that involve uncertainties about the future,” senior author Gideon Nave said in a University of Pennsylvania news release. He’s an assistant professor of marketing at the university’s Wharton School. The research team gathered brain scans and genetic data from more than 12,600 people of European ancestry and then from another 13,000 people. All were aged 40 to 69 and enrolled in the UK Biobank. Investigators used self-reported risky behaviors — smoking, drinking, sexual promiscuity and driving above the speed limit — to create an overall indicator of risk tolerance. They estimated the relationship between total gray matter volume across the brain and the risk-tolerance score. Higher risk tolerance was correlated with overall lower gray matter volume, researchers said, though only an association was seen. Gray matter carries out the basic functions of…  read on >  read on >

Another Deadly Disease for Smokers: Pulmonary Fibrosis

By | | Add a Comment

Current and former smokers are at risk for a lung disease called pulmonary fibrosis, but many aren’t aware of the threat, the Pulmonary Fibrosis Foundation says. There is no cure for the disease, which affects more than 200,000 Americans. A recent foundation survey found that more than 80% of smokers are unfamiliar with pulmonary fibrosis. This is a concerning statistic among a group disproportionately affected by the disease. Both smokers and nonsmokers have little awareness of the disease, and nearly 9 out of 10 Americans don’t know its symptoms: shortness of breath, a dry, chronic cough and fatigue. “Smokers are often aware that tobacco usage can lead to diseases such as lung cancer, COPD and emphysema, among others. However, as smokers experience chronic symptoms similar to those of PF, such as a dry, persistent cough, it is important they discuss PF with their doctors,” Dr. Amy Hajari Case said in a foundation news release. She’s senior medical adviser of education and awareness. It’s never too late to stop smoking, the foundation emphasized. Quitting smoking can increase overall health and quality of life at any age by reducing loss of core lung function over time and increasing lung capacity, which is crucial to maintaining a healthy blood oxygen level. Giving up the tobacco habit may also reduce inflammation of the airway, which can take months or…  read on >  read on >
