Some people who have been dealing with COVID-19 symptoms for months are getting hope with a new diagnosis.Doctors are starting to recognize a syndrome called POTS in some of them. It stands for postural orthostatic tachycardia syndrome.POTS is a disorder of the autonomic nervous system, which is responsible for controlling things like our heart rate and blood pressure.It's estimated as many as 3 million people in the U.S. have POTS, not connected to COVID-19, but it's a new diagnosis for some post-COVID patients.“One has to have pots like symptoms at least more than 6 months before we can diagnose pots and that's another reason we are only beginning to recognize pots now because the pandemic started earlier this year and although we feel like it’s been going on forever, we are only recognizing it now,” said Dr. Tae Chung, Director of the Johns Hopkins POTS Clinic.Chung just opened a clinic dedicated to post-COVID patients with POTS-like symptoms about a month ago. Those symptoms include lightheadedness, prolonged fatigue and brain fog.It is a hard condition to recognize and doctors are being cautious in diagnosing it.“The symptoms to a medical provider, they may seem kind of non-specific. Oh you've had an infection, you're going to be tired, but no when people have lightheadedness that is severe and seems to be disabling and limiting activity, we need to be thinking about the possibility of an autonomic disorder,” said Dr. Brent Goodman, who runs the Autonomic Lab at the Mayo Clinic in Scottsdale, Arizona.Goodman has also been seeing post-COVID-19 patients who have developed POTS.The treatment is individualized but can include exercise, changing up how much salt is in your diet, and medication.It's not clear yet how recovery will be for post-COVID-19 patients. Both doctors agree that the sooner someone can be diagnosed, the better for starting treatment. 1894

Sometimes, it's nice to eat healthy. Other times, you just want artificial flavoring in your cereal.General Mills gets that now. A year and a half after the company removed artificial colors and flavors from its Trix cereal, it's bringing them back."Classic Trix" -- the bright, rainbow version from your childhood -- will hit shelves in October, the company announced Thursday.The news was first reported by the Wall Street Journal.The all-natural Trix -- called "No, No, No" Trix -- will still be available to consumers who want to cut factory-made dyes from their diet. That version gets its more muted coloring from fruit and vegetable juices and spice extracts, like turmeric and annatto, which is derived from the achiote tree.General Mills announced in 2015 that it would remove artificial flavors and colors from all its cereals."We're simply listening to consumers and these ingredients are not what people are looking for in their cereal today," Jim Murphy, president of the company's cereal division, said in a statement at the time.The changes to Trix took effect in January, 2016.But fans of that earlier recipe for Trix believe they were misheard."Our Trix fans have been calling us, emailing us and reaching out to us on social media asking if we would consider bringing back the original formulation of Trix cereal with its vibrant colors. As a result, we are launching 'Classic Trix' to fill these consumer requests," General Mills spokesman Mike Siemienas said Thursday to explain the change.Siemienas said the company doesn't have any plans to change up the ingredients in its other cereals. Artificial flavoring and coloring has also been removed from Reese's Puffs, Cocoa Puffs, Golden Grahams, Chocolate Cheerios, Frosted Cheerios and Fruity Cheerios since the 2015 announcement.The back and forth comes at a tough time for the cereal business.General Mills reported lower quarterly earnings than expected on Wednesday, with overall sales down 4%. It was the ninth consecutive quarter that revenue fell when compared to the year before.The problem: Americans just aren't consuming as much cereal for breakfast. General Mills' cereal sales in the U.S. fell 7% from one year ago, the company said.Competitor Kellogg faces similar problems. The company said last month that sales for "morning foods," including Frosted Flakes, Rice Krispies and Pop-Tarts, have also dropped in the past year. 2428

Some 220 children from separated families remain in custody, four months after a judge ordered the US government to reunite the immigrant families it split up at the border.And 14 of those children were only just added to the list the government uses to track reunifications, officials revealed in court documents filed late Thursday night.The acknowledgment that more families were separated than previously reported is likely to spark concern from advocates, who've frequently questioned the accuracy of the government's record-keeping in the aftermath of the family separation crisis.A review of records prompted the Office of Refugee Resettlement to add 14 more children to its tally, the court filing said. Government attorneys said they've "been careful to re-evaluate and refine the numbers" as they learn new information.The numbers appear in the latest federal court filing in the American Civil Liberties Union's class-action case over family separations. They come as a caravan of migrants, which includes many families, treks through Mexico, bound for the US border -- and as the Trump administration considers a new pilot program that could result in the separations of kids and parents once again."Given the lack of a plan or system to keep track of families, it's no surprise the original numbers were inaccurate," said Lee Gelernt, deputy director of the ACLU's Immigrants' Rights Project and the lead attorney in the case.Advocates have warned that inaccurate statistics could have serious consequences, prolonging family separations and making it harder for the public to track the government's progress in complying with the court's order.Officials have stressed that the numbers are constantly changing, and attorneys are still debating them as they meet to sort out the next steps. Meanwhile, the statistics released in the case's regular court filings offer one of the few public windows into the reunification process.The filing shows some progress in the reunifications -- a painstaking effort that has stretched for months as officials tracked down parents who were deported without their children and coordinated repatriation flights. More than 40 children have been discharged since the last status report in mid-October, and officials said 47 more are on track to be released.But most of the kids from separated families who remain in custody -- more than 75% -- will not be reunified with their parents either because the parents have declined reunification or because officials have deemed reunification cannot occur since the parent is unfit or poses a danger, the filing said. 2616

Some of the top scientists and doctors in the country are calling on leaders to do something different immediately to improve the state of the COVID-19 pandemic.The American Association of Medical Colleges released a road map to reset the country's approach to the crisis. It includes evidence-based actions to improve outcomes and overall health.Improvements include things the country still hasn't got a grip on, like critical supply and drug shortages, increasing testing, an setting national standards for face coverings.“There is literally no risk to wearing a mask for the average person. You may be uncomfortable, you may be hot, you may break out, but it is nowhere as uncomfortable as it would be for having me or one of my colleagues intubate you and put you on a ventilator for an extended period of time,” said Dr. Atul Grover, Executive Director at the AAMC Research and Action Institute.A recent study by Duke of various face masks found the N95 respirator with no valve is the most effective. But these should be reserved for health care workers.A disposable surgical mask made from a plastic material called polypropylene was the next best option.Third was a mask with two layers of cotton and one layer of synthetic material.Masks made from cotton fabric alone, as well as knit t-shirts, performed about the same.“So, you are also protecting yourself,” said Grover. “In fact, if we can get up to 80, 90% of us wearing masks in a community, you could start to reduce that transmission by 2 or 3% at a pretty steady rate.”The AAMC roadmap to reset also mentions an immediate need for something we haven't seen yet, a vaccine distribution plan.“But somebody needs to sit down and say within those high-risk groups of comorbidities, whether that’s diabetes, obesity, hypertension, heart failure, who should be vaccinated first? Is it by age? Is it by condition? And even among first responders, do I start with police doctors, paramedics?”The Centers for Disease Control and Prevention (CDC) has not released a vaccine distribution plan. It has asked four states and one city to draft plans for how they would distribute and who would get priority. Those plans will be shared with other states. 2215

St. Louis Zoo officials are trying to solve the mystery of how a 62-year-old ball python laid seven eggs without being around a male python for at least two decades. An expert at the zoo says it’s unusual but not rare for ball pythons to reproduce asexually. Pythons also sometimes store sperm for delayed fertilization. The zoo say the birth is also unusual because ball pythons stop laying eggs long before they reach their 60s. The python laid the eggs in July. Three of the eggs remain in an incubator, two were used for genetic sampling and snakes in the other two eggs did not survive. 599
