山东严重痛风病的治疗(山东痛风疾病期多长时间) (今日更新中)

The FDA has ended an emergency use authorization (EUA) order for hydroxychloroquine, saying that the agency has determined that drug is "unlikely to be effective in treating COVID-19."In the announcement, the agency said that the benefits of hydroxychloroquine and a related drug, chloroquine phosphate, "no longer outweigh the known and potential risks for the authorized use."The FDA issued the EUA for the drug in March. In April, the FDA warned that the drug should only be used in hospital settings due to the severe side effects some experienced while taking the drug.Shortly after the coronavirus arrived in the United States, President Donald Trump touted the drug as a potential treatment for the disease. He encouraged those sickened with the virus to take the drugs, saying, "what do you have to lose?"Trump said he took the drug for a few weeks in May as several White House staffers contracted the virus. In an open letter, White House physician Sean Conley said he prescribed the drugs after determining that the "potential benefit from treatment outweighed the relative risks."Earlier this month, a study showed that the drug was likely not effective in treating COVID-19. That study was published just days after a separate study — which determined that people who took the drugs died at a higher rate than those who did not take the drugs — was retracted by three of its authors. 1404

The Centers for Disease Control and Prevention is asking people who take a COVID-19 vaccine to download a smartphone app so it can continue to track side effects.The app, called V-Safe, uses text messages and web surveys from the CDC to check in with patients who have gotten a COVID-19 vaccine.The app will also remind patients when it's time to go back for a second shot.Patients can expect to experience mild symptoms like fever, headache and muscle aches after taking the vaccine. But doctors, like Dr. Grace Lee — the associate chief medical officer for practice innovation at Stanford Children's Health and a member of the CDC's vaccine advisory panel — say those side effects don't tend to last very long."We hope that patients will be willing to engage in the system, recognizing it does take some time," Lee said. "But it's really important for all of us in the U.S. to make sure that we are helping to create a robust vaccine safety monitoring system for all COVID vaccines."Lee says that because clinical trials for COVID-19 vaccines have been so large — with 30,000 to 60,000 people in each trial, compared to just several thousand for a typical trial — there's already a lot known about the vaccines.The trials have shown no major safety risks thus far, but Lee says rare adverse events can happen — like the two healthcare workers in Alaska earlier this week who suffered anaphylactic allergic reactions with the Pfizer vaccine. The side effects reported by those two patients were similar to the ones suffered by two people in the U.K. earlier this month.Lee says that's why the CDC is counting on as many people as possible to use V-Safe."My hope is that if the numbers are high," Lee said. "It just means it gives us more information more quickly, and so for anything rare that might occur, we would be able to pick it up much more quickly."V-Safe send text messages to patients, asking them how they are feeling for up to six weeks after their shots. The CDC says the questions take less than five minutes to answer and that the information patients provide will be confidential and private. 2117

The FDA has given the final go-ahead to Pfizer-BioNTech's coronavirus vaccine.Shots will begin in a few days after the decision, but initial doses will be scare and rationed to health workers and nursing home residents and staff first. Enough vaccinations for the general population isn't expected until spring, prompting experts to urge the public to continue using face coverings and physically distance through the winter.Authorization had been expected Saturday morning, after an advisory panel recommended approval of the vaccine Thursday evening. According to reports, the agency was working to move it up to Friday evening.Friday morning, President Donald Trump lashed out at the Food and Drug Administration and its commissioner, Dr. Stephen Hahn, for not moving faster. Trump tweeted the FDA “is still a big, old, slow turtle. Get the dam vaccines out NOW, Dr. Hahn @SteveFDA. Stop playing games and start saving lives!!!” 939

The digital news company Mic has laid off most of its staff, a spokesperson for the company confirmed.The layoffs were first reported Thursday by Recode. It is not yet clear exactly how many employees were affected. Mic declined to comment beyond confirming the Recode report.The company was founded in 2011, and for the past several years has branded itself as a news website geared toward millennials.Mic Publisher Cory Haik also resigned Thursday. In a note to staff that was obtained by CNN Business, Haik called journalism a "tough business.""Our business models are unsettled, and the macro forces at play are all going through their own states of unrest," she wrote. "If anyone tells you they have it figured out, a special plan to save us all, or that it's all due to a singular fault, know that is categorically false. Like the truth, it is indeed complicated."Mic was once a digital media darling, attracting around million in funding from investors. Its biggest backers included Lightspeed Venture Partners, Clark Jermoluk Founders Fund, WPP and WarnerMedia. (WarnerMedia owns CNN.)The company's staff swelled to more than 100 people by early 2016, according to The New York Times, which asked in an article published at the time: "What happens when millennials run the workplace?"But the climate is a tough one for digital media publishers right now. Ad revenue alone hasn't been enough to support these businesses, and Google and Facebook have substantial control over the ad market.Refinery29, HuffPost and Vocativ have all cut staff in the past year. So have CNN Digital, Vice and BuzzFeed.Mic laid off 25 employees in August 2017 as part of a pivot to video. Co-founder and CEO Chris Altchek told staff at the time that the shift was needed because "visual journalism already makes up 75% of the time that our audience spends" with the site.There were signs this year that the environment wasn't improving for Mic. Digiday reported in April that traffic to Mic's website had been plunging.The article also noted that Mic was very reliant on Facebook, citing statistics that showed views on the social media site fell to 11 million views in March compared to 192 million about a year earlier.Still, company executives pushed back on some reports that characterized the situation at Mic as particularly dire. When the Columbia Journalism Review reported in September that the company's board discussed a possible shutdown, Altchek called the report "categorically false."Emily Singer, a senior political reporter at Mic, tweeted Thursday that she was leaving the company."I'm so proud of what we've accomplished here," Singer wrote.Kerry Lauerman, Mic's executive news director, tweeted about the "gutting experience" Thursday."But only love for the extremely resilient and open-hearted team of Mic editors, producers, writers and shooters I had the great honor of working with," he added. "They performed brilliantly often under a cloud of uncertainty."Reached by phone, Lauerman declined to comment further, saying only that the team was packing up all of their things.Several other employees also tweeted news of their departures."I have so much to say, but most importantly the time I spent at @mic was the best of my career," wrote Managing Editor Colleen Curry. "I learned so, so much from brilliant people dedicated to keeping journalism alive."Mic is also in talks to sell at least part of the company to Bustle Digital Group, Recode reported Wednesday. A source with knowledge of the potential deal confirmed that report to CNN Business. 3572
