Rafael Nadal, the current No. 2-ranked tennis player in the world and winner of 19 career Grand Slam titles, won’t play in the upcoming US Open citing coronavirus concerns.Nadal, 34, is chasing Roger Federer for most career Grand Slam titles as both players head toward the twilights of the careers. For Nadal the spread of the coronavirus took precedence to catching Federer, who has won 20 Grand Slams.“The situation is very complicated worldwide, the COVID-19 cases are increasing, it looks like we still don’t have control of it,” Nadal said on Tuesday. “We know that the reduced tennis calendar is barbaric this year after 4 months stopped with no play, I understand and thank for the efforts they are putting in to make it happen.”The tennis calendar was scaled back in March as the coronavirus began to spread worldwide. This year’s Wimbledon tournament was canceled altogether, while the French Open, a tournament Nadal has won a record-setting 12 times, has been postponed to early October.Despite major tournaments being postponed, players have continued playing competitive matches, sometimes amid controversy. Early in the summer, tennis star Novak Djokovic organized an Eastern Europe tournament that ignored coronavirus safety measures. The tournament’s final ended up being canceled, and a number of players, including Djokovic, ended up with coronavirus infections. 1389

President Donald Trump sought to buy all the dirt on him collected by the tabloid National Enquirer and its parent company American Media Inc., according to a new report.Trump and his former personal attorney Michael Cohen devised a plan to purchase potentially damaging stories about Trump from AMI, The New York Times reported Thursday, citing several of Trump's associates.The plan was never finalized, according to the Times. Lawyers for Trump and Cohen declined to comment to the newspaper, as did AMI.The information gathered on Trump dating back to the 1980s includes older stories and notes about Trump's marital woes, lawsuits and tips about alleged affairs, among other things, according to the Times.Last week, Jerry George, the former Los Angeles Bureau Chief for the National Enquirer, told CNN's Erica Hill on "Erin Burnett OutFront" that American Media head David Pecker kept a safe in which he held "particularly sensitive story files," including source agreements and contracts. The Associated Press first reported on the safe. 1052

Researchers published what they say is the first case of a living person diagnosed with the degenerative brain disease chronic traumatic encephalopathy or CTE.While unnamed in the study, lead author Dr. Bennet Omalu confirmed to CNN that the subject of the case was former NFL player Fred McNeill -- who died in 2015.Omalu is credited with first discovering CTE in professional football players. Until now, the only way to diagnose the disease is with a brain exam after death.The diagnosis was first made using an experimental brain scan that can trace a signature protein of CTE called tau. The authors then confirmed the diagnosis with an autopsy. The case study was published in the journal Neurosurgery this week.'It looked like just depression'Omalu first presented these findings exclusively to CNN's chief medical correspondent, Dr. Sanjay Gupta, in 2016. McNeill's wife, Tia, and his two sons, Gavin and Fred Jr., told Gupta then that they saw Fred transform from a fun loving family man at the center of their lives into a man who was dealing with symptoms of memory loss, anger and depression that tore their family apart."There are some times where the father is the stronghold in the family, or the anchor. If you lose that, everything kind of falls apart. That's kind of what happened for us. It looked like financial issues at first; it looked like marital issues, and they separated; then it looked like just depression," Gavin told Gupta.CTE is known for plaguing people with Alzheimer's like symptoms such as memory loss, rage, mood swings, and in some cases, suicidal ideation.Severity of the disease is categorized into four stages, with stage 4 being the most severe. While researchers don't know exactly why certain people develop the disease and others don't, they believe that it results from repeated blows to the head that trigger a build up of tau proteins in the brain.CTE has been called football's "concussion crisis," however experts point out that CTE can develop from any repeated head injury. According to the Boston University CTE Center, "this trauma includes both concussions that cause symptoms and subconcussive hits to the head that cause no symptoms." These subconcussive hits can include the repeated trauma the brain experiences from constant plays, hitting the turf, and tackling. Wrestlers, boxers, and military troops have also been diagnosed with the disease.Seeing CTEWhile McNeill is the first case to be confirmed with an autopsy, the experimental technology has been used on at least a dozen other former NFL players, including Pro Football Hall of Famer, Dallas Cowboy Tony Dorsett. Omalu helped develop and is invested in the diagnostic exam, which uses a radioactive "tracer" called FDDNP to bind to tau proteins in the brain. The tau proteins can then be seen on a PET scan of the brain.Critics have said the protein also can highlight another protein called amyloid, which may be indicative of Alzheimer's or other forms of dementia. But Omalu noted that in CTE, tau makes distinctive patterns in the brain. It has a "specific topographic signature," he said, and that pattern can be detected in imaging.Omalu said he and his team are currently raising money to start a phase 3 clinical trial to further test the technology and replicate what they have seen in McNeill. He anticipates that once funds are raised, it will take another two to three years for the trial and then another year, at least, for approval from the US Food and Drug Administration. When asked, how soon a commercial test could be available, Omalu predicted it could be as soon as a few years. "We are looking at less than five years," he said.  3711

Public transit across the country has seen a roller coaster of ridership since the pandemic first hit. Now, it looks to the future and the hope that riders return."A lot of medical workers ride transit every day, people who work in distribution centers, grocery stores, these are people who keep cities running, and we really need transit to carry these workers through the depths of this pandemic," said Ben Fried of Transit Center, a non-profit that advocates for better public transportation in American cities.Fried says public transit nationwide has seen fewer riders than normal ever since stay-at-home orders were first enacted."We have seen transit climb back a little bit in terms of ridership. At the peak, it was down 90-95%. Now, depending on the system, it's typically down about 75% of normal rates," Fried said."(We've seen) a significant decrease. We normally carry 400,000 riders a day. We saw that drop to 100,000 early on," said Terry White, the Interim General Manager of King County Metro in Seattle.White said King County had to cut unused bus routes and then add service to the southern region of the county, which still saw a high number of passengers during the height of the pandemic."(We) almost didn't miss a beat in terms of the ridership coming out of that area," White said. "So, we assume there are a lot of folks in those areas that have to get to these essential services, food, healthcare, frontline jobs you can't do from home."While public transportation departments across the country reorganize their transit routes and implement new safety, cleaning and social distancing efforts on buses and subway cars, they're concerned about how the future of public transit will look. Fried hopes more people realize public transportation is still safe during the pandemic.Fried pointed to New York City as an example."Transit ridership has really increased a lot since the depths of the pandemic," Fried said. "We're not back to normal by any means, but as transit ridership has increased, we have not seen a spike in COVID cases. So, that's one indication transit may be safer than people think it is."Still, the overall decline in ridership isn't good for public transportation agencies' bottom lines."Transit agencies depend on revenue from a variety of sources," Fried said. "It's a mix of fare revenue, dedicated taxes, so like a local sales tax, a percentage of which will go to transit, and state and local government support and all three of these are getting hammered various degrees from COVID."In Seattle, King County Metro depends on local sales tax and money made from bus and subway fares to keep them going."Really, our outlook for the next 10 years in this COVID pandemic situation has us in a situation where we will have to make up probably about billion over the next ten-year period," White said.Recently, King County Metro laid off 200 part-time employees while also offering early retirement incentives to some full-time workers, despite receiving a good chunk of money from the CARES Act. Fried is advocating for more federal help to keep public transit moving.As the pandemic moves forward, Fried hopes passengers start to get comfortable with using public transportation again."I think the number one thing to realize is that our collective health and safety is dependent on people wearing masks," he said. "It's true in shared space, and it's true in transit."Fried hopes ridership in the U.S. can get back to normal levels soon, but King County Metro doesn't think that will happen anytime soon. 3563

RAMONA (KGTV) - — The owner of Ramona Fitness Center is trying to rally business owners to stand up for their rights and consider defying San Diego County public health orders that require many businesses to close.“They’re forcing us out of business," Peter San Nicolas told ABC 10News in an interview Tuesday. "They’ll force people to not be able to pay for food and pay for home, for somewhere to live. We’re talking about basic necessities and they’re pushing us to the limit.”Gyms are among the sectors ordered to cease all indoor operations after the county moved into the state's purple, or worst, tier. This comes as the county recorded 1,546 new COVID-19 cases Tuesday, a single-day record.San Nicolas makes the case that gyms can open safely and that forcing them to close will not stop the spread. “We haven’t had any issue with it here in the gym. We’ve had over 25,000 check-ins just since June and we’ve had no cases of covid here at the gym.”According to the latest outbreak numbers on the county website, only 0.4% of all cases recorded between June 5 and November 14 have been tied to gyms. However, many public health experts say there is no question gyms should be closed during this most recent surge. "Gyms are one of the riskiest possible businesses," said Dr. Rebecca Fielding-Miller, an epidemiologist who teaches at UC San Diego, in an email to ABC 10News. "By definition, people are breathing heavily in an indoor space, which is a recipe for spread. And while I haven’t been inside a gym since March, I would hazard a guess that gyms that are threatening to defy county orders are also not gyms that are enforcing masking policies. They should absolutely be closed."During the last COVID-19 surge in August, Ramona Fitness Centers became one of the first and only businesses cited and then charged by the District Attorney for remaining open in violation of public health orders. San Nicolas says he expects the County to come after him again. He is represented by a legal team attempting to sue for businesses to stay open. 2059
