In a finding that should encourage scientists who are racing to develop coronavirus vaccines, a new study out of Iceland suggests that immunity to the disease may not be as fleeting as first thought. Among 30,000 Icelandic residents who were tested for antibodies to COVID-19, researchers discovered the antibodies stayed in people’s systems for at least four months, the study found. Of those who tested positive for the coronavirus, 487 had received multiple antibody tests. In the first two months after a patient was diagnosed, the antibodies that can confer immunity rose significantly. For the next two months, antibody levels remained stable, according to the study published Tuesday in the New England Journal of Medicine. In a commentary that accompanied the study, scientists from Harvard University and the U.S. National Institutes of Health noted that while the Icelandic research focused on a largely homogeneous population, “this study provides hope that host immunity to this unpredictable and highly contagious virus may not be fleeting and may be similar to that elicited by most other viral infections.” Earlier research on coronavirus antibodies had indicated that immunity might be short-lived, leaving people vulnerable to reinfection. But the Icelandic study offers hope that a vaccine that triggers a strong immune response will have a longer-lasting effect than some had believed. Interestingly, the Icelandic researchers also found that women, nonsmokers…  read on >

Cellphone activity could be used to monitor and predict spread of the new coronavirus, researchers say. They analyzed cellphone use in more than 2,700 U.S. counties between early January and early May to identify where the phones were used, including workplaces, homes, retail and grocery stores, parks and transit stations. Between 22,000 and 84,000 points of publicly available, anonymous cellphone location data were analyzed for each day in the study period. Counties with greater declines in workplace cellphone activity during stay-at-home orders had lower rates of COVID-19, according to findings published Aug. 31 in the journal JAMA Internal Medicine. Researchers said their findings suggest that this type of cellphone data could be used to better estimate COVID-19 growth rates and guide decisions about shutdowns and reopenings. “It is our hope that counties might be able to incorporate these publicly available cellphone data to help guide policies regarding reopening throughout different stages of the pandemic,” said senior study author Dr. Joshua Baker, an assistant professor of medicine and epidemiology at the University of Pennsylvania School of Medicine. “Further, this analysis supports the incorporation of anonymized cellphone location data into modeling strategies to predict at-risk counties across the U.S. before outbreaks become too great,” he added in a university news release. Baker said it also may be possible to use cellphone data to forecast hotspots and take…  read on >

The U.S. Department of Agriculture (USDA) announced on Monday that it would extend its flexible free school meals program through the fall, to help keep millions of kids fed as the coronavirus pandemic continues to hold the country in its grip. The program, which allowed parents and caregivers to collect free meals for their kids at any school this summer, was set to expire at the start of September but pressure had been mounting on the agency to continue the program, the Washington Post reported. In mid-August, Secretary of Agriculture Sonny Perdue said that extending the full scope of the free meals for kids program beyond August would go “beyond what [the] USDA currently has the authority to implement and would be closer to a universal school meals program which Congress has not authorized or funded.” However, Perdue said in a statement released Monday that his agency was “extending summer meal program flexibilities for as long as we can, legally and financially.” The statement said the millions of families that rely on the program would be able to do so until as late as the end of the year. “We appreciate the incredible efforts by our school foodservice professionals year in and year out, but this year we have an unprecedented situation,” Perdue said. “This extension of summer program authority will employ summer program sponsors…  read on >

Drug use is common among people taking part in virtual raves and happy hours during the coronavirus pandemic, a new study finds. “We explored whether stay-at-home orders changed how people use drugs — and it appears that drug use during virtual gatherings is somewhat prevalent among the party-going population we studied,” said study author Joseph Palamar. He’s associate professor of population health at NYU Langone Health in New York City. The researchers conducted online surveys in April and May 2020 with 128 New Yorkers who said they attend electronic dance music parties and reported recent drug use. About 56% said they had attended virtual raves and about 70% attended virtual happy hours during the pandemic. Of those, more than one-third said they had used illegal drugs during the events, including 41% of virtual rave attendees and 34% who attended virtual happy hours. Seven out of 10 participants used alcohol, and 30% said they used marijuana during both types of events, the survey found. Use of other drugs was less common. At virtual raves, about 9% used ecstasy, 7% used LSD and about 4% used cocaine. Slightly more than 3% of virtual happy hour attendees used cocaine and/or ketamine. The findings suggest that virtual dance parties and nightclub events could be an opportunity for drug use outreach and education, the researchers noted in a university news…  read on >

Telemedicine might help people with stubbornly high blood pressure get their numbers down — and possibly lower their risk of heart disease and stroke in the long run, a new study suggests. Doctors already recommend that people with high blood pressure use a home monitor to track their numbers. But research suggests that home readings, alone, only make a small difference in getting the condition under control. “People really don’t have the agency to act [on those readings] on their own,” said Dr. Karen Margolis, executive director of research at the HealthPartners Institute in Minneapolis. And if there is no clear plan for what to do about high home numbers, she said, any issues may only come to light at the periodic doctor visit. So Margolis and her colleagues tested a “telemonitoring” program designed to give patients more help: Their home readings were sent electronically to a pharmacist within the health system who then had regular phone “visits” with the patients. Over the next 18 months, the tactic worked. Compared with patients on standard care, those in the telemonitoring program lowered their blood pressure by an extra 7 to 10 points, on average, the study found. And over five years, they were half as likely to suffer a heart attack or stroke, or develop heart failure, according to the report. That finding, Margolis said, fell…  read on >

The new rapid COVID-19 test approved last week is probably not the most reliable option for determining whether someone is infected. But it’s cheap and it’s fast, and if used correctly, it could be the basis of a screening strategy to keep Americans safe as they return to school and work, infectious disease experts say. The BinaxNOW COVID-19 Ag Card produced by Abbott Laboratories is an antigen test, a type of scan that looks for specific structural proteins of the coronavirus that form during infection. The test will produce results within 15 minutes and cost $5, Abbott says. Antigen tests are notorious for producing many false positives, indicating that people are infected when they really aren’t, said Dr. Gary Procop, medical director and co-chair of the Enterprise Laboratory Stewardship Committee at the Cleveland Clinic in Ohio. And he said that’s absolutely fine if the test is used appropriately, as a screening tool to make sure folks infected with SARS-CoV-2 don’t make it into a crowded school or a basketball court or an assembly line. “Whenever you do screening tests, you actually want a lot of false positives because you want to capture everybody with disease,” Procop said. The key is to make the antigen test the first in a two-step screening process, he said. Everyone who tests positive should then receive a confirmatory PCR test…  read on >

As the number of coronavirus cases in the United states passed the dubious milestone of 6 million on Sunday, a new report shows COVID-19 is now spreading at a faster rate in children and teenagers than among the general public. The troubling data, from the American Academy of Pediatrics, comes just as schools and universities around the country are reopening for fall classes. Since the start of the summer, every state in the country has witnessed an increase in the number of young people who have tested positive for coronavirus. In late May, about 5 percent of the nation’s cases were recorded in minors, the The New York Times reported. By Aug. 20, that number had risen to more than 9 percent. Young children seem to catch and transmit the virus less often than adults, but Dr. Sean O’Leary, vice chairman of the American Academy of Pediatrics’ committee on infectious diseases, told the Times that community spread in many parts of the United States this summer has corresponded with more infections among children. After reports of outbreaks at summer camps, it is clear that the virus can spread among children under certain circumstances, Dr. William Raszka Jr., a pediatric infectious disease expert at the University of Vermont’s College of Medicine, told the Times. He worries about opening schools in places where infection rates are high.…  read on >

Older Americans with depression have held up well to the threat of COVID-19, a new study finds. Researchers saw no increase in their depression and anxiety during the early days of the coronavirus pandemic. And they said these seniors showed resilience to the stress of physical distancing and isolation. “We thought they would be more vulnerable to the stress of COVID because they are, by [U.S. Centers for Disease Control and Prevention] definition, the most vulnerable population,” said study co-author Dr. Helen Lavretsky, professor-in-residence of psychiatry and biobehavioral sciences at the University of California, Los Angeles. “But what we learned is that older adults with depression can be resilient. They told us that coping with chronic depression taught them to be resilient,” she said in a university news release. The researchers, from UCLA and four other universities, interviewed people older than 60, average age 69, during the first two months of the pandemic. Participants lived in Los Angeles, New York, Pittsburgh and St. Louis, and were enrolled in studies of treatment-resistant depression. The study was funded by the University of Pittsburgh. The researchers found that the volunteers’ depression and anxiety levels, or risk of suicide, were the same before and during the pandemic. In general, participants were more concerned about the risk of contracting the coronavirus than the risks of isolation. Also, while all maintained…  read on >

Flu and pneumonia vaccines lead to fewer hospital deaths among heart failure patients, a new study finds. “Our study provides further impetus for annual immunizations in patients with heart failure. Despite advice to do so, uptake remains low,” said study author Dr. Karthik Gonuguntla, of the University of Connecticut. In heart failure, your heart can’t pump blood as well as it should. This leads to fluid buildup in the lungs that causes shortness of breath, coughing and reduced quality of life. Respiratory infections like pneumonia and the flu make heart failure worse, so annual vaccinations are recommended for patients. However, few studies have compared outcomes among heart failure patients who have and haven’t received these vaccinations. In this study, the researchers looked at nearly 3 million heart failure patients, average age 70, in the United States who were hospitalized between 2010 and 2014. Only 1.4% of the patients had received the flu vaccine and just 1.4% had received the pneumonia vaccine. Rates of in-hospital death were much lower among patients who received the flu and pneumonia vaccines (just over 1% for each) than among those who didn’t receive either vaccine (almost 4%), the researchers found. The study findings were released Friday and scheduled for presentation at the European Society of Cardiology virtual annual meeting. “Pneumonia and flu vaccines are vital to preventing these respiratory infections…  read on >

On the final night of the 2020 Democratic National Convention, the world heard from an improbable source — a 13-year-old named Brayden Harrington. Brayden was invited to speak because he has a frustrating and misunderstood condition that millions of Americans share, including Democratic presidential hopeful Joe Biden. “We stutter,” he explained in a video recorded for the virtual convention. Biden has been open about his struggle with stuttering, calling it “the single most defining thing in [his] life,” according to the Los Angeles Times. In February, Brayden met the former vice president at a New Hampshire campaign event where they bonded over their shared condition. “He told me about a book of poems by [William] Yeats he would read out loud to practice,” Brayden recalled. “He showed me how he marks his addresses to make them easier to say out loud. So I did the same thing today,” he added, turning his marked-up script to the camera to show the audience. Brayden’s speech was intended to show a vulnerable and compassionate side of the Democrats’ nominee. But it also shed light on a speech disorder that has, at times, been described as a “medical mystery,” according to Soo-Eun Chang, a professor of child and adolescent psychiatry at the University of Michigan in Ann Arbor. “In the past, people thought that stuttering was due to that…  read on >
