Top health officials are considering “pooled testing” as a way to ramp up COVID-19 tests.Here's how it works:Instead of testing each sample individually, labs pool together a certain amount, like 10, in one tube with one test.If it's negative, you double check it, and then you're done.If there's a positive, you break it down either into smaller pools or individually for further testing.“So, there are advantages, mostly cost savings, that's the huge advantage of pooling, also the ability to go through a very large volume of specimens,” said Dr. Thomas Quinn, an infectious disease researcher at National Institute of Allergy and Infectious DiseasesQuinn worked in one of many labs that used the pooling technique during the HIV epidemic in the 1980s. He says the difference between then and now is the tests themselves.Pooling dilutes the samples. The HIV tests were very accurate, so that wasn't an issue, but with COVID-19, the tests aren't as reliable.The other problem is pooling takes more time in the lab, even with robotic equipment helping.“We need to get everyone tested and everyone wants to know what's the result of my test within 24 hours. That's very hard to do with pooling,” said Quinn.Quinn isn't recommending pooling for individual testing right now. He says it could be more useful in big surveys, when it's not an emergency. 1357

There's a new warning about makeup. A watchdog group says it has found asbestos in several products, sold in a store targeted to teens and young girls. What do you think of when you hear the word asbestos?“I think of like commercials like where your loved one has been exposed to asbestos and you die,” one woman says. “I'm like, 'Oh my God,' it's terrible.”Another woman said, “Like in a house that's like shut down forever” she says. “There's asbestos in a house.”You don't usually think of makeup.Danny Katz with U.S. PIRG, a consumer watchdog group said it tested more than a dozen make up products and found "high levels of asbestos" in three. They're all sold at Claire's, a store with products aimed toward girls and young women.“It's completely unacceptable to have asbestos in these products,” Katz says. “Asbestos if you inhale it or ingested it can lead to lung cancer it can lead to mesothelioma, which is cancer of the internal organs, and if you apply it over skin over time it can also increase the risk of skin cancer."Asbestos is a naturally occurring mineral that can be found in talc, a common product in many makeup products. But Katz says it's a company's responsibility to make sure the talc it uses hasn't been contaminated.“We need Claire's to remove these products from the shelves and we need them to figure out how asbestos got in their products to begin with,” Katz says. “We need Congress and the FDA to take action. We need to ban asbestos from beauty care products and makeup.”Right now, Katz and U.S. PIRG are urging us to avoid products with talc until federal laws change.It's not the first time Claire's has come under scrutiny for this. Just four months ago, Claire's pulled some items after independent lab tests found evidence of asbestos, then said its own initial testing found no problems.Regarding these latest allegations, Claire's released a statement saying,  1952

Their youthful brains were developing normally, with no signs of developmental, psychological or neurological problems. None had ever had a concussion. But by the end of a single football season, 24 children between the ages of 9 and 18 who had more frequent impacts to the head showed signs of damage to brain development, new research says."Repetitive head impact exposure may have a cumulative effect in the rapidly developing brains of youth and high school football players," said study co-author Gowtham Krishnan Murugesan, a radiology research assistant at UT Southwestern Medical Center in Dallas, adding that the results mirror other recent findings.The study outfitted 60 youth and high school football players who had no history of head trauma or developmental issues with a head impact telemetry system that measures the magnitude, location and direction of impacts to the head. The researchers were not looking at whether the impact resulted in a concussion, only that impact occurred.The children were sorted into two categories: high cumulative head impact players (24) and low cumulative head impact players (36).Before beginning to play, each child had a resting state functional scan, known as an fMRI; the scans were repeated at the end of football season. The researchers were trying to see how exposure to repetitive hits affects the normal "pruning" process in the brain that occurs during adolescence."Pruning is an essential part of brain development," Murugesan said, comparing the process to how a tree needs to have dead or unneeded branches cut to keep it healthy and allow it to grow."Disruption in normal pruning has been shown to be related to weaker connections between different parts of the brain," he said.After comparing the functional MRI results to the player's level of impact, the researchers found that youth in the high-impact group had damage to their brains' pruning process after one season."Our study has found a significant decrease in gray matter pruning in the frontal default mode network, which is involved in higher cognitive functions, such as the planning and controlling of social behaviors, " Murugesan said.Although the "teenage years are a critical time for brain development, brain remodeling or synaptic pruning, this was a short-term study and did not follow the players longitudinally over several years. We don't really know the full application," said Dr. Julian Bailes, director of neurosurgery and co-director of the NorthShore University HealthSystem Neurological Institute, who was not involved in the research.Weill Cornell neurologist Dr. Richard Isaacson, who was also not involved in the study, called the research "early" and said the results don't necessarily "translate to a clinical or cognitive outcome." More research is needed to see whether the decline in brain pruning permanently affected the child's cognitive function or whether the brain's natural plasticity allowed it to repair itself."I would call this a pilot study," Isaacson said. "The call to action would be that we need more robust longitudinal studies with a pre- and a post-assessment of more than brain imaging. The study should also measure cognitive and neurological function and look for changes."As we learn more about the issue, Isaacson said, parents should do everything they can to limit contact in sports, "especially in practice before games, where studies show the majority of contact occurs." 3464

Things at grocery stores seem relatively calm now, in comparison to how it was back in March. Remember the toilet paper fiasco?But as we hear talk about another wave of coronavirus infections, some are wondering if grocery supplies will take another hit.We went to experts who track grocery data. They say what we saw earlier this year was historic.“Those mid-March weeks were the largest we've seen in the history of grocery shopping. I don't expect to ever see big waves like that again,” said Anne-Marie Roerink, President of 210 Analytics.People first stocked up on just cleaning items and then they started stocking up on all types of items, including pantry foods and that precious commodity – toilet paper.Roerink says that while it is possible people will stockpile again later this year, toilet paper may not be on the list. Cleaning items may become hard to find again. The timing of all this really depends on the virus and how cases evolve.“Should it come down to where the virus is big enough of a wave or we might go back down to a shelter in place, or where people feel more safe at home than they do out and about, I can see where our grocery spending will go back up,” said Roerink.Earlier this year, holidays like Mother’s Day and Father’s Day actually contributed to the clearing of grocery shelves. They’re typically holidays where we go out to eat, but that wasn't really an option in most places. So, people had to improvise.“All of a sudden, retail had to absorb all those dollars to take care of mom and cook her a fun brunch or dinner, so we had an enormous peak again for Mother's Day and Father's Day,” said Roerink.That means holidays like Thanksgiving and Christmas could change how things work out at the grocery store as well.Generally, supply and demand has started to normalize, but grocery sales are still about 10% higher than what they normally are. Though, prices could still change depending on the demand. 1952

Three NBA teams — Atlanta Hawks, Utah Jazz, and Memphis Grizzlies — have announced that they would allow a limited number of fans at games during the 2020-21 season amid the coronavirus pandemic.Last season, teams played in a bubble setting in Orlando, Florida. This season, teams will be traveling from city to city once again.Earlier in November, the Oklahoma City Thunder announced they would have a limited number of fans at the beginning of its season, but on Monday, the team changed course and decided to not allow fans at games due to rising COVID cases in the state."For months, we have worked in close collaboration with Chesapeake Energy Arena, the City of Oklahoma City, local health officials, and the NBA to put into place thorough health and safety measures to allow for reduced seating capacity," the team said in a press release. "However, as we review ongoing and concerning trends in COVID-19 cases and hospitalizations in Oklahoma, we want to exercise an abundance of caution to help control the spread of the virus in our community. Therefore, the Thunder has made the decision to begin the season without fans in the arena."The Utah Jazz announced that they would allow a limited number of fans at their home games. According to KSTU, Vivint Arena will allow 1,500 fans in the suites and lower bowl. Fans must wear face coverings and social distance while inside the arena.KSTU reported that the arena would reduce capacity in elevators, retail stores, and restrooms.Another NBA team that's allowing fans this season will be the Atlanta Hawks. According to the Atlanta Journal-Constitution, a small number of friends and family will attend the first few home games at State Farm Arena. Approximately 1,500 fans will be able to watch the Hawks game on Martin Luther King Jr. Day.And according to the Memphis Grizzlies, the seating capacity at the FedExForum will be at about 20% capacity. The Grizzlies said that everyone inside the arena would need to wear a mask at all times, and everyone will need to social distance. The team also announced that they would install more than 300 hand sanitizing stations would be placed throughout the arena for easy and ample access for guests.The 2020-21 season is set to tipoff Dec. 22, with teams playing 72 games. And last week, the league announced the structuring and format of how games were to be played during the coronavirus pandemic.In a press release, the league said that the regular-season would be released in two segments: the first half schedule will be released around the start of training camp, which is reportedly beginning the first week of December. The league will release the second-half portion towards the end of the first half of the season.Other notable changes occurring this season, per a press release by the league:Each team will play three games against each intraconference opponent, with each pairing featuring either two home games and one road game or one home game and two road games. Within each team's division, the league office has randomly assigned which two opponents will be played twice at home and which two opponents will be played twice on the road.A play-in tournament will determine the seventh and eighth playoff seeds.All five teams from within a division will play all five teams from one other intraconference division twice at home, and all five teams from the remaining intraconference division twice on the road.Each team will play two games against each interconference opponent (30 total games per unit), with each pairing featuring one home game and one road game.The NBA also released this tentative calendar of important dates for the upcoming season:Dec. 11-19, 2020: Preseason gamesDec. 22, 2020 – March 4, 2021: First Half of regular seasonMarch 5-10, 2021: All-Star breakMarch 11 – May 16, 2021: Second Half of regular seasonMay 18-21, 2021: Play-In TournamentMay 22 – July 22, 2021: 2021 NBA Playoffs 3937
