If pandemic-related stress has you grinding your teeth, you’re not alone. Dentists say tooth-grinding and jaw-clenching are on the rise due to the many challenges stemming from the COVID-19 pandemic. “We’ve been seeing an increase in the number of patients looking for appointments to replace broken mouth guards” that have been cracked or chewed through, said Dr. Leopoldo Correa, director of the Craniofacial Pain Center at Tufts University School of Dental Medicine, in Boston. Grinding and clenching (“bruxism”) can cause cracked teeth, fillings and crowns; migraines and other headaches; face, neck and jaw pain. “You may resolve a stressful situation in the short term, or it may continue and develop into chronic stress,” which can result in symptoms such as fatigue, increased muscle tension, depression, an inability to fall or stay asleep, and bruxism, Correa said. “According to some data, the amount of force we create when clenching the jaw is around 300 pounds,” he said in a school news release. Five to 10 minutes of jaw and face exercise each day can help you cope, Correa suggested. Here’s what to do: Keep your teeth apart, bend your fingers and place your knuckles on each side of your face. Give yourself a self-massage, pushing down. If possible, briefly apply heat or an ice pack to the side of the face before doing the stretching exercise.…  read on >  read on >

Expanded unemployment benefits, passed by Congress last spring to ease the economic pain of the pandemic, appear to have held hunger at bay for millions of Americans, new research shows. Called “The CARES Act” when it was put into effect nearly a year ago, the law expanded who is eligible for unemployment benefits and how long that coverage would last. A weekly federal supplement of $600 was also added to the coverage. The move ultimately cut in half the chance that a middle-class recipient would need to eat less because of financial hardship, the study authors said. And it cut by roughly one-third the risk that a recipient would face so-called “food insecurity.” The U.S. Department of Agriculture defines food insecurity as “limited or uncertain access to adequate food.” “The COVID-19 recession is markedly different from prior recessions in that it is so concentrated among people in low-income households,” explained study author Julia Raifman. She’s an assistant professor in the department of health law, policy, and management at Boston University School of Public Health. “This has led to millions of people experiencing food insecurity,” Raifman said. “And households with children are more likely to report food insecurity,” with potentially dire implications. For example, it is “not possible for children to concentrate on school if they do not have enough to eat. And there will be…  read on >  read on >

Stress levels are on the rise as Americans grapple with the COVID-19 pandemic and bitter political divisions, a new American Psychological Association (APA) survey shows. On a 10-point scale where 1 means little to no stress and 10 means a great amount, adults’ average stress level clocked in at 5.6, according to the Stress in America: January 2021 Stress Snapshot. That’s higher than levels reported in APA surveys since April. Eighty-four percent of respondents in the latest survey reported feeling at least one emotion associated with prolonged stress in the prior two weeks. The most common were anxiety (47%), sadness (44%) and anger (39%). And two-thirds said they feel overwhelmed by the number of issues facing the nation. Significant sources of reported stress included the future of the United States (81%); the coronavirus pandemic (80%); and political unrest (74%). Two-thirds said the Jan. 6 attack on the U.S. Capitol was a significant source of stress. Among other key findings: 84% of respondents say the nation has serious societal issues that need to be addressed and 9 in 10 hope that there will be a move toward unity. “Nearly a year into the pandemic, prolonged stress persists at elevated levels for many Americans. As we work to address stressors as a nation, from unemployment to education, we can’t ignore the mental health consequences of this global…  read on >  read on >

Like influenza, could COVID-19 evolve to wax and wane with the seasons? New research suggests it might. Early in the pandemic, some experts suggested that SARS-CoV-2 — the virus that causes COVID-19 — may behave like many other coronaviruses that circulate more widely in fall and winter. To find out if that could be true, researchers analyzed COVID-19 data — including cases, death rates, recoveries, testing rates and hospitalizations — from 221 countries. The investigators found a strong association with temperature and latitude. “One conclusion is that the disease may be seasonal, like the flu. This is very relevant to what we should expect from now on after the vaccine controls these first waves of COVID-19,” said senior study author Gustavo Caetano-Anollés. He is a professor at the C.R. Woese Institute for Genomic Biology at the University of Illinois at Urbana-Champaign. The same research team previously identified areas in the SARS-CoV-2 virus genome undergoing rapid mutation. Similar viruses have seasonal increases in mutation rates, so the researchers looked for connections between mutations in SARS-CoV-2 and temperature, latitude and longitude. “Our results suggest the virus is changing at its own pace, and mutations are affected by factors other than temperature or latitude. We don’t know exactly what those factors are, but we can now say seasonal effects are independent of the genetic makeup of the virus,”…  read on >  read on >

Consuming greater amounts of certain omega-3 fatty acids found in fish may reduce the risk of asthma in kids — but only those with a common gene variant, British researchers say. They focused on the long chain omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which are known to have anti-inflammatory properties. “Asthma is the most common chronic condition in childhood and we currently don’t know how to prevent it,” said study senior author Seif Shaheen, of Queen Mary University of London. “It is possible that a poor diet may increase the risk of developing asthma, but until now most studies have taken ‘snapshots’, measuring diet and asthma over a short period of time,” he said in a university news release. To find out if intake of omega-3s might matter, the researchers analyzed data on more than 4,500 Britons who were born in the 1990s and whose health has been tracked since birth. The researchers analyzed the association between intake of EPA and DHA from fish at 7 years of age and rates of newly diagnosed asthma in these kids as they reached 11 to 14 years of age. Overall, omega-3 intake from fish was not associated with asthma onset. But it did seem tied to a lower odds for asthma in a subgroup of children with a particular genetic makeup.

There have been good and bad changes to U.S. children’s diets during the COVID-19 pandemic, researchers say. “Providing healthy meals and snacks to our kids can be a challenge even when we’re not experiencing a pandemic,” said senior study author Susan Carnell. She’s an associate professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine, in Baltimore. “The pandemic has massively disrupted families and caused a lot of stress, and this has naturally affected interactions around food,” Carnell said in a school news release. To find out how the pandemic is affecting children’s diets, the Johns Hopkins Medicine researchers surveyed 318 parents of children aged 2 to 12 across the United States. Parents who reported higher levels of stress due to the pandemic were more likely to use food to manage children’s emotions and behaviors. For example, they might use less healthy food and snacks, such as cookies, to reward their children, the study found. Stress specifically related to COVID-19 among parents was also associated with children eating more sweet and savory snacks throughout the day. But the survey also revealed some positive trends. For example, 75% of respondents said their children had regular breakfast, lunch and dinner times. The researchers also found an association between lower stress levels, consistent mealtimes and routines, and positive food-related interactions, such as parents eating…  read on >  read on >
