This week marks Lead Poisoning Prevention Week, and according to the Centers for Disease Control and Prevention, 3.6 million Americans face a risk of lead poisoning from lead-based house paint.The CDC says that even low levels of lead in the bloodstream can cause cognitive impairment in children that is irreversible.“As we observe National Lead Poisoning Prevention Week, we urge people to take action,” said Patrick Breysse, PhD, CIH, Director of CDC’s National Center for Environmental Health. “Together, we can eliminate childhood lead poisoning as a public health problem by strengthening blood lead testing, reporting, and surveillance, while linking exposed children to recommended services. CDC is committed to help address this threat and improve health outcomes for our nation’s most vulnerable citizens – our children.”The CDC is encouraging parents to get their children’s lead levels checked by a doctor. The CDC says that the screening is covered for those on Medicaid.While homes older than 42 years old may contain leaded paint, other risks could come from the environment, and exposure to lead-containing products such as antique cookware and leaded crystal glassware.For more information on lead poisoning, click here. 1245

Three UCLA basketball players accused of shoplifting in China last week were flying back to Los Angeles on Tuesday, the commissioner of the Pacific-12 athletic conference said, hours after US President Donald Trump said he asked his Chinese counterpart to help in the case.The three freshmen -- LiAngelo Ball, Cody Riley and Jalen Hill -- were allowed to leave China on the US-bound flight after the situation was "resolved to the satisfaction of the Chinese authorities," said Larry Scott, commissioner of the Pac-12 Conference, of which UCLA is a member."We are all very pleased that these young men have been allowed to return home to their families and university," Scott said in a news releaseThe three were arrested last week while their team was in the Chinese city of Hangzhou ahead of the squad's season opener in Shanghai. They were questioned on suspicion of stealing sunglasses from a Louis Vuitton store near their hotel.The trio stayed at the hotel, reportedly awaiting next steps in their case, while their teammates went to Shanghai, where UCLA defeated Georgia Tech 63-60 on Saturday. The three also remained in China as their team returned to the United States over the weekend.Scott did not say how the case was resolved; a conviction of grand larceny in China could result in years of prison. But Trump said Tuesday that he had asked Chinese President Xi Jinping to help.UCLA's trip coincided with Trump's two-day state visit to the Chinese capital, Beijing, as part of his 13-day trip to Asia. Trump told reporters Tuesday that Xi had been helpful in working to resolve the case.Scott acknowledged Trump, among others, in his statement."We are grateful for the role that our Chinese hosts played, and for the courtesy and professionalism of the local authorities," Scott said. "We also want to acknowledge UCLA's significant efforts on behalf of their student-athletes."Finally, we want to thank the President, the White House and the US State Department for their efforts towards resolution."Trump's request was first reported by the Washington Post.  2086

This week, experts are sending warnings to those considering seeing people outside their household without quarantining first. One aerosol expert weighs in on just how dangerous the holiday could be."My simplest advice is it is not a good idea to meet with people outside of your household for a holiday meal. That’s the most important message that can be underscored, and the reason for that is there are multiple ways this virus can be transferred,” said Alex Huffman, an aerosol expert and associate professor at the University of Denver. “The closer you are increases the chances of that, but aerosols can come out of your mouth and mix into the room. The longer you're in that room, the more chance you have of getting sick.”Huffman says time, ventilation and proximity have a big impact on whether coronavirus droplets can spread and infect others."When you breathe and talk, the louder you talk, droplets and aerosols come out of your mouth. So, traditionally, droplets are on the bigger side, aerosols are on the smaller side," said Huffman.With no mask on, these droplets can land on the faces of people around you or on their plates."And so, the biggest danger with the Thanksgiving meal or holiday meal or any meal specifically, restaurants included, are that you have to take off your mask to eat and that is why eating together indoors is so dangerous," said Huffman.Huffman demonstrated how fast droplets can spread in the air by showing how quickly food coloring can spread in water. He also analyzed the risks of eating a Thanksgiving meal in person, taking commonly-used models and applying varying factors that come into play when eating with people outside of your household."And then, I used the same model to say, ‘What happens if we meet for holiday meals?’ Let's say we have 10 people. We all eat for two hours. We all don't have masks on, and then, we ran different scenarios. If it was a small room, a large room, a medium-sized room and then estimate the amount of risk that would be from aerosol," said Huffman.Matching with community transmission rates, Huffman estimated that the probability of each person at the table having COVID-19 was about 5 percent."If it's a small room, everybody has something like a 15 percent chance of getting infected, even if we had no idea if anybody was infected or not. If it's a big room, it's a little bit less than that," explained Huffman.Ventilation also comes into play, which is why experts are advising that if you really are planning to meet with family this holiday, do it outside. Opening windows and doors also helps. Huffman also has some tools people can use, such as a carbon dioxide monitor or you can create your own box fan air filter."On the back, this is a furnace filter that’s also 20 inches and so you tape them together so they're well-sealed. You turn it on high and you blow the air through this filter and that removes the particles in the room that could potentially contain virus in it," said Huffman.Still, Huffman and other medical experts agree this won't completely eliminate the risk of spreading COVID-19. The safest thing to do is stay home and avoid celebrating Thanksgiving with people who are not part of your household. 3230
