House Speaker Paul Ryan found out that he is part Jewish as part of the upcoming season of PBS' show "Finding Your Roots."The show's host, Henry Louis Gates Jr., shared the Wisconsin Republican's reaction to discovering his roots during a panel on Tuesday."You could have knocked him over with a feather and then he was very proud of it," Gates, who also serves as an executive producer on the show, said during the Television Critics Association press tour in Los Angeles.A publicist for the show confirmed Gates' comments during the panel, and Ryan's upcoming appearance on the show, in an email to CNN."We don't know who that Jewish person was, but we know it was on his mother's German line, which makes sense," Gates continued. "So somebody who was a Christian German slept with a Jewish German person and that's where that came from."In a tweet on Wednesday, Ryan, who is Catholic, seemingly hinted at finding out about his roots."Guess I need to start saying 'L'Chaim' now, too!" he tweeted, attaching a GIF of himself holding up a drink. He did not reference the show itself in the social media post.PBS said in a news release that the new 10-episode season of "Finding Your Roots" -- which debuts in January -- also features Republican Sen. Marco Rubio of Florida and Democratic Rep. Tulsi Gabbard of Hawaii.Last year in an episode of the show, comedian Larry David and Vermont's independent Sen. Bernie Sanders found out they were related.Other guests this upcoming season include CNN's Christiane Amanpour and "Game of Thrones" author George R.R. Martin.The-CNN-Wire 1585

How accurate are the coronavirus tests used in the U.S.?Months into the outbreak, no one really knows how well many of the screening tests work, and experts at top medical centers say it is time to do the studies to find out.When the new virus began spreading, the Food and Drug Administration used its emergency powers to OK scores of quickly devised tests, based mainly on a small number of lab studies showing they could successfully detect the virus.That’s very different from the large patient studies that can take weeks or months, which experts say are needed to provide a true sense of testing accuracy.The FDA’s speedy response came after it was initially criticized for delaying the launch of new tests during a crisis and after the Centers for Disease Control and Prevention stumbled in getting its own test out to states.But with the U.S. outbreak nearly certain to stretch on for months or even years, some experts want the FDA to demand better evidence of the tests’ accuracy so doctors know how many infections might be missed.There have been more than 2 million confirmed coronavirus cases in the U.S. and more than 115,000 deaths, according to data compiled by Johns Hopkins University. Cases in nearly half of U.S. states are rising.In recent weeks, preliminary findings have flagged potential problems with some COVID-19 tests, including one used daily at the White House. Faulty tests could leave many thousands of Americans with the incorrect assumption that they are virus-free, contributing to new flare-ups of the disease as communities reopen.“In the beginning, the FDA was under a lot of pressure to get these tests onto the marketplace,” said Dr. Steven Woloshin of Dartmouth College, who wrote about the issue in the New England Journal of Medicine last week. “But now that there are plenty of tests out there, it’s time for them to raise the bar.”The FDA said in a statement that it has already asked multiple test makers to do follow-up accuracy studies, although it didn’t say for how many of the more than 110 authorized screening tests. The agency also said it is tracking reports of problems. Accuracy has also been an issue with blood tests that look for signs of past infections.No screening test is 100% accurate. So details on accuracy are routinely provided for tests of all types, including seasonal flu, hepatitis, HIV and cancers. For example, rapid flu tests are known to miss 20% or more of all cases, a factor doctors weigh when treating patients who have symptoms but test negative.For now, most COVID-19 tests in the U.S. don’t give data on real-world performance, including how often the tests falsely clear patients of infection or falsely detect the virus. That information is lacking for all but a few of the roughly 80 commercial screening tests available, according to an Associated Press review.The government’s emergency authorization process “requires a lower level of evidence,” the agency said. Makers need only show that a test “may be effective” instead of the usual requirement to demonstrate “safety and effectiveness.” They would have to meet that higher threshold once the U.S. government declares the emergency over.Many of the commercial test makers submitted results from 60 samples, the minimum number required and mostly used lab-produced specimens of the virus. The FDA now recommends the use of nasal swabs or other real samples from people screened for coronavirus.Experts say larger patient studies patients are needed to assess a test’s true performance.Lab testing bears little resemblance to actual — sometimes imperfect — conditions at hospitals, clinics and testing sites noted Dr. Robert Kaplan of Stanford University.“You’re testing people in parking lots, the patients themselves are extremely anxious and often unable to follow instructions,” said Kaplan, a former associate director of the National Institutes of Health.Kaplan and others say those differences could explain why some tests are not performing as expected.Last month, the FDA warned doctors of a potential accuracy problem with Abbott Laboratories’ rapid ID Now test, which delivers results in roughly 15 minutes. The test has been lauded by President Donald Trump and used to screen the president, his staff and visitors to the White House.The FDA alert followed a preliminary report by New York University that found Abbott’s test missed between a third to one-half of infections caught by a rival test in patients screened for the virus.Abbott rejected the findings, saying the researchers did not follow the instructions for using its test. The company pointed to alternate patient studies, including its own, that have found the test successfully detects between 91% and 95% or more of virus cases when compared to other tests.But similar problems with ID NOW’s accuracy have been flagged in preliminary reports by researchers at Stanford University, Loyola University and the Cleveland Clinic.For now, the FDA is requiring Abbott to conduct follow-up studies in several different patient groups.The FDA’s emergency standards “are still high but there is a significant difference in the body of work that what would go into a submission under the normal process,” said Abbott vice president John Hackett. “Our normal process takes years to bring these out.”Requiring bigger studies of all coronavirus tests could provide valuable information, but it could also strain the FDA’s already stretched staff and resources, said Dr. Daniel Schultz, former director of the FDA’s medical device center.Dr. Colin West of the Mayo Clinic worries doctors and patients have put too much confidence in the current crop of tests, when an unknown number of patients with COVID-19 are likely receiving false negative results.Even a modest error rate can have grave consequences during an outbreak like COVID-19. West gives the example of a test that is 95% accurate at detecting the virus and is used on 1 million people. That would still result in 50,000 people being incorrectly told that they don’t have the virus.“The negative test does not mean that I’m off the hook,” West said. “We just need to maintain that level of vigilance until we have a better sense of how good these tests really can be.”___Follow Matthew Perrone on Twitter: @AP_FDAwriter.___Follow AP pandemic coverage at http://apnews.com/VirusOutbreak and https://apnews.com/UnderstandingtheOutbreak.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

In a pandemic that relies heavily on the expertise and passion of our healthcare workers, we have seen many doctors and nurses working longer hours and even risking their own health to care for those in need.“This is a pandemic that's going to continue to go on. And a lot of health care providers in different settings have already been asked to work overtime shifts or extra shifts. And the thing is, that’s just increasing the burnout,” said Dr. Jessica Rainbow, RN and UArizona College of Nursing assistant professor.“Before the pandemic burnout was already a normalized issue in Nursing. And what I mean by that is that more nurses than not experienced burnout than those who have what I would call good well-being and don't suffer from burnout,” said Chloe Littzen, RN and UArizona College of Nursing Ph.D. candidate.Rainbow and Littzen are seeking ways to mitigate nurse burnout during the coronavirus pandemic. They say the pandemic has only intensified the problem.“They either leave the setting that they're in. Let's say they're in one unit, they go to another unit. They leave that facility going from, let's say, the hospital setting to the community setting or vice versa, or they leave nursing completely,” said Littzen.That puts the industry in a tough spot. The nursing shortage also affects the ability to educate future nurses and the ability to do more research.“It's important to say that this is not an issue that is the nurse's fault right or any healthcare provider or anyone who works in a healthcare setting,” said Rainbow.From their research, they say health care workers are shown to have good self-care, but it’s the systems of the work environment that can be stressful.“Where they're actually given the resources that they need to be successful. So resources as far as things like PPE, things like having adequate staffing,” said Rainbow.They say a big factor is also the public. Loved ones of those in care can help by being understanding and by adhering to guidelines, such as wearing a mask.“You know, it's important to give grace and struggling times and everyone's emotions are heightened and stressed and you know nurses are people, too. They're also a human being and they're also suffering with you,” said Littzen.They found nurses have done things like meditation, spending more time in nature, and seeking peer groups to voice shared experiences.“Social support is huge for nurses. I mean, especially to when you were a provider and you have a job where your significant other at home may not fully understand what you do. And so it's difficult sometimes if you don't have the social support of other co-workers in the same position,” said Rainbow.Rainbow’s study is called “Working in Healthcare During the COVID-19 Pandemic. Participants can access the consent form with study information online or contact her for more information. Littzen’s dissertation study is called “Young Adult Nurse Work-Related Well-being, Contemporary Practice Worldview, Resilience, and Co-Worker Support.”This story was first reported by Taja Davis at KGUN in Tucson, Arizona. 3106

IMPERIAL BEACH, Calif. (KGTV) -- It appears the “Don Juan” thief one woman says loves stealing from women on first dates is a wanted man.Last Friday, 10news recounted Elizabeth’s so-called “date from hell.”  Elizabeth, 23, says the man is a good-looking guy in his late 20s who was a Facebook friend for two years.  They had mutual friends in common but had never met. RELATED: 'Don Juan' thief targeting women, some on first datesHe messaged her recently, asking her out to a sushi lunch. She agreed, but during the drive, she says he fidgeted with his blinkers and asked her to exit the SUV to make sure they were working. She agreed, and that's when he took off, with her purse, wallet, and sunglasses.When she posted his photo on Facebook, she says she got a flood of responses: dozens of other women with similar stories of theft."One woman said, 'He told me he had a gift for me in the trunk, and as soon as I got out, he drove off with my purse and several hundred dollars,'" Elizabeth recalls.She says none of the women called police because the man told them he had friends in a cartel.  But apparently at least one woman did. Sources tell 10news an arrest warrant has recently been issued for him after a different local woman accused him of stealing money and other property valued at more than 0.10news has also learned the man pleaded guilty in 2015 to embezzling from his employer - Walmart - and received a sentence of three years probation.10new has not identified the man in Elizabeth’s case because detectives haven’t officially confirmed he is the wanted man.If you have any information, please call San Diego Police at (619) 531-2000. 1700
