Scientists say they are seeing signs of lasting immunity to the coronavirus, even in those who only experience mild symptoms of COVID-19. A slew of studies show that disease-fighting antibodies, as well as B-cells and T-cells that can recognize the virus, appear to persist months after infections have run their course, The New York Times reported. “This is exactly what you would hope for. All the pieces are there to have a totally protective immune response,” said Marion Pepper, an immunologist at the University of Washington and an author of one of the new studies, which is now undergoing review by the journal Nature. “This is very promising,” said Smita Iyer, an immunologist at the University of California, Davis, who is studying immune responses to the coronavirus in rhesus macaques, told the Times. “This calls for some optimism about herd immunity, and potentially a vaccine.” Although researchers cannot predict how long these immune responses will last, experts consider the data to be the first proof that the body has a good chance of fending off the coronavirus if exposed to it again. “Things are really working as they’re supposed to,” Deepta Bhattacharya, an immunologist at the University of Arizona, told the Times. Bhattacharya is an author on one of the new studies, which was published on medRxiv, a pre-print server for health research that has…  read on >

Microscopic bits of plastic have most likely taken up residence in all of the major filtering organs in your body, a new lab study suggests. Researchers found evidence of plastic contamination in tissue samples taken from the lungs, liver, spleen and kidneys of donated human cadavers. “We have detected these chemicals of plastics in every single organ that we have investigated,” said senior researcher Rolf Halden, director of the Arizona State University (ASU) Biodesign Center for Environmental Health Engineering. There’s long been concern that the chemicals in plastics could have a wide range of health effects ranging from diabetes and obesity to sexual dysfunction and infertility. But the presence of these microscopic particles in major organs also raises the potential that they could act as carcinogenic irritants in much the same way as asbestos, Halden explained. “It is not always necessarily the chemistry that harms us. Sometimes it’s the shape and the presence of foreign particles in our bodies,” Halden said. “We know the inhalation of asbestos leads to inflammation and that can be followed by cancer.” Previous research has shown that, on average, people ingest about 5 grams of plastic every week, the equivalent of a credit card, said Dianna Cohen, CEO of the nonprofit Plastic Pollution Coalition. “It’s heartening to see quality quantitative research being performed on humans to assess the cumulative harmful…  read on >

Women with early-stage breast cancer whose surgery has been postponed during the coronavirus pandemic need not worry about the delay, new study findings suggest. A longer time from diagnosis to surgery doesn’t affect overall survival of women with early-stage tumors, the researchers found. They also said a delay didn’t lower survival among women with estrogen-sensitive, early-stage breast cancer who received neoadjuvant endocrine therapy before their surgery. “Usually we take these patients with very small tumors directly to surgery, so it is a big change in practice to first put those patients on tamoxifen or an aromatase inhibitor,” said lead study author Dr. Christina Minami, an associate surgeon at Brigham and Women’s Hospital in Boston. “What we can say from our findings is that despite the delay in surgical therapy, because you were on neoadjuvant endocrine therapy, we do not think that your survival will at all be impacted,” she added in a news release from the American College of Surgeons. For the study, her team used data on nearly 379,000 women. One group had ductal carcinoma in situ — the earliest form of breast cancer. The other group had small invasive tumors — stage 1 and 2 — that had not spread to lymph nodes and were estrogen receptor-positive. The researchers wanted to know if waiting up to one year from diagnosis to surgery affected…  read on >

In a potential harbinger of what could unfold on college campuses across the United States this fall, the University of North Carolina at Chapel Hill said Monday it will revert back to online teaching after testing showed a rapid spread of coronavirus among students. The university was one of the largest schools in the country to bring students to campus for in-person teaching, The New York Times reported. Officials announced the abrupt change just a week after classes began at the 30,000-student university, the newspaper said. Online instruction for undergraduate students will take effect Wednesday. Why the switch? Out of hundreds tested, 177 cases of COVID-19 had been confirmed among students, the Times reported. Another 349 were in quarantine because of possible exposure to the virus, officials said. Clusters of coronavirus cases have already popped up in three residence halls and a fraternity house. “We understand the concern and frustrations these changes will raise with many students and parents,” UNC-Chapel Hill’s Chancellor Kevin Guskiewicz and Provost Robert Blouin said in a statement, the Times reported. “As much as we believe we have worked diligently to help create a healthy and safe campus living and learning environment, we believe the current data presents an untenable situation.” On Monday, a new report highlighted another untenable situation: COVID-19 cases among nursing home residents have jumped nearly 80% this…  read on >

Some of the leading hotspots in the United States are on track to become even more sweltering in the coming decades — thanks to a combination of greenhouse gas emissions, urban development and population growth. In a new study, researchers estimate that over the course of this century, the biggest relative increases in extreme heat will hit cities in the Sunbelt — including Atlanta; Austin, Texas; Miami and Orlando, Fla. And lest Americans outside those areas breathe a sigh of relief, the study also warns of rising temperatures in major metropolises like New York City, Los Angeles and Washington, D.C. That is, at least, if no efforts are taken to counter the trend. The projections are based on a “business-as-usual” model, explained lead researcher Ashley Broadbent. He’s an assistant research professor at Arizona State University, in Tempe. “We’re imagining what would happen if we keep going along as we are,” said Broadbent, who noted that’s not an unrealistic assumption. “But,” he stressed, “there are things we can do.” The biggest and broadest would be tackling greenhouse gas emissions — heat-trapping gases that are spewed into the air when fossil fuels (like coal, oil and natural gas) are burned. But on the local level, Broadbent said, greenhouse gases are not the only contributor to rising temperatures and people’s actual experience of heat. There are also factors…  read on >

As the school year begins across America under the shadow of COVID-19, a new survey shows most parents are feeling overwhelmed and abandoned. Just 1 in 7 parents said their children would be returning to school full time this fall, and most children need help with remote schooling, The New York Times survey released Wednesday found. Yet, 4 in 5 parents said they would have no help in that endeavor, whether from relatives, neighbors, nannies or tutors. As well, more than half of parents said they will be taking on this burden while still holding down paid jobs. Of course, when both parents are wage earners who need to work outside the home, they cannot be in two places at once. But three-fourths of these parents said they will be overseeing their children’s education, and nearly half plan to handle child care, according to the survey of more than 1,000 parents polled between Aug. 4 and Aug. 8. Of the parents who are both working remotely during the pandemic, 80 percent will also handle child care and education, the survey showed. One in five are considering hiring a private teacher or tutor to help with remote learning. “All the choices stink,” Kate Averett, a sociologist at the University at Albany in New York who has been interviewing parents since the spring, told the Times. “There…  read on >

People with diabetes face a higher risk of developing complications from COVID-19, but a new survey reports they have also suffered more economic fallout from the pandemic. In June, 18% of people with diabetes were out of work compared to 12% of the general population. And one-third of people with diabetes have lost at least some income since the pandemic began versus about 29% of the general population, the survey released by the American Diabetes Association and dQ&A found. That loss of work and income can have immediate and serious consequences for people with diabetes. Nearly one in four people with diabetes — and half of those who’d lost income since the pandemic began — said they had to dip into savings, take out a loan or use their stimulus money to get their diabetes supplies. Worse, one in four people with diabetes have rationed their insulin, other medications or diabetes supplies. (Rationing insulin can lead to serious illness requiring hospitalization, and even death.) “When you lose your job, you lose your health insurance. When you lose your health insurance, you might ration your medicines, and then people end up with poorer outcomes. This was going on well before COVID, but now COVID has cast a very bright light on an existing problem,” said Tracey Brown, CEO of the American Diabetes Association. The new research…  read on >

Child abuse reports have plunged during the coronavirus pandemic, a troubling sign that the constraints of social distancing may mean thousands of cases are being missed, a new survey suggests. The survey, conducted by the Children’s National Alliance, found that children’s advocacy centers across the country reported serving 40,000 fewer children nationwide during the first six months of this year than the same period last year, the Washington Post reported. In 2019, more than 192,000 children were served by the centers while just over 152,000 were helped in 2020, a 21 percent drop, the survey showed. But in no way can the decline be viewed as good news, said Teresa Huizar, executive director of the alliance. “We have absolutely no reason to believe the actual incidence rate has declined,” she said. “What we really believe is that there are 40,000 fewer kids that haven’t been saved from abuse.” “What we were dreading did in fact happen,” Huizar told the Post. And the damage may be even more widespread, since the numbers from the centers, which receive referrals from child protective services departments and law enforcement, do not take into account all child abuse reports nationwide. A full third of U.S. counties don’t even have access to a children’s advocacy center, the Post reported. More than two-thirds of child abuse cases are reported by teachers and…  read on >

Be careful that the COVID-19 information you’re getting is accurate and not opinion masquerading as the real McCoy, says the American College of Emergency Physicians. Watch out for bold claims and instant cures touted on social media or by friends. Get health and medical information from experts like the ACEP and the U.S. Centers for Disease Control and Prevention, the physicians’ group says. “A troubling number of purported experts are sharing false and dangerous information that runs counter to the public health and safety guidelines endorsed by ACEP and the nation’s leading medical and public health entities,” said Dr. William Jaquis, president of the college. “This kind of misinformation can not only be harmful to individuals, but it hinders our nation’s efforts to get the pandemic under control,” he added in a college news release. You should know that there is no cure or vaccine for COVID-19. Scientists keep learning more about the virus and how to treat it. COVID-19 can be spread by anyone — even people who don’t think they’re infected. About 40% of those infected don’t have symptoms, but can spread the virus. The virus isn’t harmless, and its long-term effects are still being studied. Without a cure, the best defense is making smart choices and safe behaviors, the college says. “There are still many questions about COVID-19, but we know these…  read on >

Depression, anxiety and inactive lifestyles are all too common among college students, and a new study finds they may have escalated during the initial outbreak of COVID-19. Using a mix of smartphone data and online surveys from more than 200 students, researchers at Dartmouth College determined that the coronavirus pandemic had an immediate impact on the mental health of this particular undergraduate group. The students involved in the study were participating in a research program tracking mental health at the New Hampshire university. They reported spikes in depression and anxiety at the beginning of the pandemic in early March, just as the school pushed students to leave campus and begin remote learning. While their self-reported anxiety and depression lessened slightly later on in the semester, the study found that their overall anxiety and depression levels remained consistently higher than in previous years. “We observed a large-scale shift in mental health and behavior compared to the observed baseline established for this group over previous years,” said study author Jeremy Huckins, a lecturer at Dartmouth. In addition, around spring break period in mid-March, the students reported that their day-to-day lives were dramatically more sedentary than previous terms. “This was an atypical time for these college students. While spring break is usually a period of decreased stress and increased physical activity, spring break 2020 was stressful and confining…  read on >
