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

To know how a pandemic and politics have impacted Nogales, Arizona, Aissa Huerta will tell you to just look around.“It’s another world here, so often, it’s missed,” said Huerta.On the street that’s home to her art gallery, steps from the border, there’s not much to see at all. Morley Avenue is empty, many of the stores are closed.“We don’t have shoppers,” said business owner Evan Kory, who owns La Cinderella.For more than seven decades., Kory's family has owned stores in Nogales. The Arizona border city has a population of around 20,000 people. On the other side of the border wall is Nogales, Mexico, a city with a population of more than 200,000 people.Since March, the Mexican-American border has been closed to non-essential travel. The rules mean Mexican shoppers and the millions of dollars they spend in Arizona must stay on the other side of the wall.Kory says at least 90 percent of his store’s customers are from Mexico.“We’ve always been dependent on population in Mexico to support our local economy, so as soon as that’s cut off, our economy is shut down essentially,” he explained.Air travel isn’t restricted, but policy says people must have an essential reason to drive or walk across the border.For now, the restrictions that have been extended monthly since March, mean Alex La Pierre can’t lead tours across the border for his non-profit, the Border Community Alliance, a group that aims to show how concrete and barbed wire can’t divide two cities with powerful similarities.“The more opportunities that we can get to, citizen to citizen, one on one, to meet our neighbor and to see that we’re all not that scary that we have a lot of common interests,” La Pierre said.“The worst part is we can’t share what we love about this area,” said Chef Minerva Orduno Rincon, who has led tours with BCA, using food to create a connection across the border.In this part of Arizona, it’s less about what’s considered Mexican or American.“Really it feels like one whole city here, just divided by a fence,” said Nogales high schooler Ingrid Torres.Many of Torres’ friends live and Mexico and she hasn’t seen them since the pandemic began.For locals like Aissa Huerta, the closer you live to the border, the easier it can be to see through the narratives about immigration often written by those who live far away.“You hear about the worst-case scenario or the drug busts or immigration, so you hear the atrocities of this area without ever getting the opportunity for residents here to tell their story or what it's like to live on the border of two different nations,” Huerta said. 2604

Ticketmaster has issued a response regarding Billboard's report that concertgoers would have to verify that they've been vaccinated or tested negative for the virus before attending a live show.In an email to E.W. Scripps, Ticketmaster said there is no requirement coming from them about mandating vaccines or testing for future events.In the original report, Billboard reported that the ticket-selling company would set up a way for the customers' COVID test results to be sent to third-party health companies. And through its digital app, Ticketmaster would tie those test results or vaccination status to a ticket digitally that'd be used to enter events.Ticketmaster explained that it is up to the event organizers to set policies around safety and entry requirements."Ticketmaster does not have the power to set policies around safety/entry requirements, which would include vaccines and/or testing protocols, a spokesperson for Ticketmaster said. "That would be up to the discretion of the event organizer, based on their preferences and local health guidelines."The spokesperson explained that they are exploring the ability to enhance their existing digital ticket capabilities amid the pandemic."One path Ticketmaster is actively exploring and working to develop is a framework for syncing with third-party healthcare providers to link COVID vaccine status and/or test results to fans' digital tickets for event entry," the spokesperson said. "All aspects of vaccine verification/testing for the broad public would be set by regional health officials. Any health information would be stored with third-party health care providers with HIPPA compliance, not with Ticketmaster."In a statement, Ticketmaster President Mark Yovich added that the company's goal is to "provide enough flexibility and options that venues and fans have multiple paths to return to events.""We imagine there will be many third-party health care providers handling vetting - whether that is getting a vaccine, taking a test, or other methods of review and approval - which could then be linked via a digital ticket so everyone entering the event is verified," Yovich said. "We are working to create integrations to our API and leading digital ticketing technology as we will look to tap into the top solutions based on what's green-lit by officials and desired by clients."Ticketmaster added that this is still in development. Once the technology and regulations are approved, the company said they would make it available, but there is no timeline for implementing this potential idea."In short, we are not forcing anyone to do anything," the spokesperson said. "Just exploring the ability to enhance our existing digital ticket capabilities to offer solutions for event organizers. Just a tool in the box for those that may want to use."The spokesperson stated that Ticketmaster has set up its SmartEvent Suite, which would help event organizers safely welcome concertgoers back to live events. 2987

They ran the table. And gold was waiting for them at the end.Team USA finished one of the most unlikely runs in recent Olympic memory with a 10-7 win over Sweden in the men's curling gold medal match at the 2018 Pyeongchang Games, a feat immediately dubbed the "Miracurl on Ice."The squad turned around a 2-4 start to round-robin play with five straight wins in their final five curling matches, including Saturday's final.PHOTOS:?American curlers stun the world, take home gold medalThat final match was a 5-5 tie entering the eighth end (much like a baseball inning) with Team USA having the final shot and a chance at the equivalent of a grand slam home run. Skipper John Shuster threaded the needle for a perfect shot to take two Sweden stones out of the scoring range and give America five scoring stones, creating a virtually insurmountable 10-5 lead.Shuster's journey of Olympic bronze in 2006, followed by failure in 2010 and 2014 and eventual removal from the U.S. team, was one of high emotion. It was his perfect-when-it-had-to-be shot that defeated Canada in the preliminaries and kept America alive, followed by his cathartic tears in an interview with?NBC Sports.Team USA's Matt Hamilton also grew into a bit of a cult star with his mustacheoed presence that helped draw the viral support for this team of everyone from Aaron Rodgers...Win. #powerofthestash https://t.co/UTLIKPaKpA— Aaron Rodgers (@AaronRodgers12) February 24, 2018 1499
