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

TOKYO (AP) — The five Olympic rings are back in Tokyo Bay. The rings were removed for maintenance four months ago shortly after the Tokyo Olympics were postponed until next year because of the COVID-19 pandemic. The rings are positioned on a barge and stand about 15 meters tall and 33 meters in length — about 50 feet tall and 100 feet in length. The Olympic rings will be lighted at night and are situated in the shadow of Tokyo's famous Rainbow Bridge. The Olympics are to open on July 23, 2021, followed by the Paralympics on Aug. 24. Organizers are confident that 15,400 Olympic and Paralympic athletes can safely enter Japan during the pandemic. 659

TOPEKA, Kan. – Republican Rep. Roger Marshall has won an open Senate seat in Kansas in a tougher-than-expected race that saw his Democratic opponent far outraise him.Marshall is an obstetrician who has represented western and central Kansas in Congress for two terms. He prevailed against Democratic state Sen. Barbara Bollier.Marshall entered the campaign with the GOP’s traditional advantages in a state that tends to vote for conservatives. Republicans haven’t lost a Senate race in Kansas since 1932. But Bollier, a former Republican, excited Democrats and raised more than million to set a Kansas record that Marshall couldn’t match.Bollier pitched herself as an independent and common-sense centrist, but Marshall portrayed her as too liberal for Kansas.Marshall will succeed retiring four-term Republican Sen. Pat Roberts. 841

There have been 12 Hurricane Irma-related deaths throughout the state of Florida, Alberto C. Moscoso, a spokesman for Florida Division of Emergency Management, said Tuesday evening.As nightfall approached Tuesday, many people from South Carolina to Florida were staying in darkened homes, dealing with fallen trees and blocked roadways, and hoping they could find gas.The situation in the Sunshine State was trying the patience of people who rode out the storm and those who came home to find widespread devastation and access to their neighborhoods limited at times.Photos of Hurricane Irma's destruction?Power outages in Florida affected almost 5 million homes, organizations and businesses, among them gas stations, which need the electricity to keep pumps working.Two days after Irma made landfall on Cudjoe Key, authorities and a few residents were finally able to reach some of the Florida Keys on Tuesday.What they found was devastating: Based on initial estimates, 25% of the houses on the chain of islands have been destroyed, the Federal Emergency Management Agency said Tuesday. Another 65% suffered major damage."Basically, every house in the Keys was impacted some way," FEMA Administrator Brock Long said.It's still not clear how many casualties Irma caused on the Keys.It's a long wait for those sifting through what's left of their homes throughout Florida in the oppressive heat and high humidity -- doing so while they wait for the power, and thus the air conditioning, to come back on.All customers who lost electricity on the eastern side of the state will likely have power restored by the end of this weekend, Florida Power & Light said Tuesday.An FPL official told reporters at a Broward County news conference that of the 790,000 customers in that county who lost power, 330,000 had their electricity restored Tuesday.The company is focusing its efforts first on schools, hospitals and other critical infrastructure. Gas stations and restaurants are next on the plan, the official said.Customers on the west coast of Florida, where Hurricane Irma made its final landfall, will likely have power restored by September 22, the company has said.But residents like William Rose have bigger concerns. Rose still can't reach his family on the Florida Keys, where about a quarter of the islands' houses are annihilated.He's not sure whether his mother, stepdad, grandmother and aunt survived Irma's wrath."I have no idea, but I'm trying to stay positive," Rose said.Before the Keys lost cellphone service, Rose received a text from his mother, who chose not to evacuate."This is terrible. I will never do this again," the text read. "I'm so glad you got out." 2688

There are new concerns about people's ability to understand information regarding the COVID-19 pandemic.Dartmouth College researchers found many health agencies are publishing coronavirus information at a 10th grade reading level.The Centers for Disease Control and Prevention, as well as the American Medical Association and National Institutes of Health say information should not be published at more than an 8th grade reading level.Researchers say it could lead to more people missing information.“If high quality information, in terms of content, like with the CDC, WHO and other official organizations put out, if that is difficult to access, difficult to understand, then that does create a potential or an incentive for looking at less trustworthy sources,” said Joseph Dexter, Neukom Fellow at Dartmouth College.Researchers say health agencies need to use short and direct sentences when writing health information. They should also use short paragraphs, avoiding jargon and technical terms.It's also important to think about how information can be presented visually on a screen.Right now, it's not required that states follow these guidelines, but it is highly recommended. 1192
