As screen time becomes a bigger part of students’ lives, preserving their vision is something to keep an eye on.Dr. Lauren Schneider, an ophthalmologist who has been treating patients in New York and Connecticut for six years warned screen time can cause a number of symptoms, including squinting and eye-crossing.“We do know that prolonged near work can place some children at risk for progressive myopia, which is worsening nearsightedness,” Dr. Schneider said.Doctors say tips on preserving your kids' vision during remote learning include making sure they keep a safe distance from their devices — at least 15 inches away from the screen is recommended — having them take screen breaks every 20 minutes and investing in a blue light blocker, which can be put on devices or glasses.“Some of our data suggests blue light emitted from our electronic devices may potentially be harmful long term to the center of the retina,” said Schneider Sunday.As school districts in the tri-state area continue to reopen this fall with full remote or hybrid learning models that include screen-based instruction, eye protection is another safety measure doctors say parents should have their sights on.“We want to make sure that while our students are hard at work which is going to require a lot of time in front of the computer that we’re avoiding unnecessary eye strain," Schneider said.According to medical experts, the full long term impacts on the eyes from remote learning are still being looked at, regular eye exams are highly recommended.For more tips and resources:www.visiontolearn.orgwww.childrenseyefoundation.orgwww.kidshealth.orgThis story was first reported by Jennifer Bisram at PIX11 in New York City, New York. 1726

As we head into cold and flu season, you can expect things will be handled differently at workplaces, schools, day cares and medical offices because of COVID-19.Anyone with symptoms like a runny nose, a cough or sneezing will likely be asked to stay home.“So, I think there's going to be a requirement for any of these symptoms for employee health at the workplace to take a larger role in screening patients probably a lot more testing,” said Dr. Scott Joy, Chief Medical Officer at Englewood Primary Care.Joy spoke with us about how people should handle these symptoms during the COVID-19 pandemic. He recommends staying home for 24 hours when you have a cold without a fever.If you have a fever, isolate for up to six days or until you've been fever free for a full 24 hours. If you're coughing or sneezing more than four times in an hour, you should probably stay home and see a doctor.“We haven't had a metric like that before, so we're going to experiment with that data point and see what it does to our workforce and our clinic infection control over this season,” said Joy.Joy also reminds people to get the flu shot.A study in the New England Journal of Medicine found people who got the vaccine had 25% fewer episodes of upper respiratory infections than those who didn't. That means fewer sick days from work and fewer doctor visits.The hope is that COVID-19 measures like handwashing, mask wearing and watching your distance will lead to fewer respiratory infections overall. But should you experience those symptoms, you may be directed to urgent care centers instead.The idea is to keep doctor offices sterile, so people with chronic conditions and other issues feel safe coming in to see their primary care physician.“In the last couple of months, people that have been putting off their care, I just diagnosed a gentleman, new diagnosis with pancreatic cancer,” said Joy. “We're detecting breast cancer, heart disease blood pressure that is out of control.”Urgent care centers are equipped with personal protective equipment and are typically faster, and cheaper than a visit to a hospital emergency room. But you should call your doctor's office first to see what they recommend based on your symptoms. 2228

ATLANTA (AP) — Marjorie Taylor Greene has won the Republican nomination for Georgia’s 14th Congressional District. She’s a businesswoman who has expressed support for the far-right conspiracy theory QAnon and been criticized for a series of racist comments. Neurosurgeon John Cowan was defeated in the primary runoff for the open seat on Tuesday. Greene's victory comes despite several GOP officials denouncing her campaign after videos surfaced in which she expresses racist, anti-Semitic and anti-Muslim views. She has responded to the criticism by blasting “the fake news media” and “the DC swamp.” Her victory comes in a deep-red area in northwest Georgia. 668

As the Democrats kicked off Night No. 1 of its four-night virtual national convention, George Floyd’s brother Philonise Floyd spoke out against his brother’s death.Philonise Floyd led the convention in a moment of silence in honor of his brother and others who have died as victims of "hate and injustice.""George should be alive today,” Philonise Floyd said. “Breonna Taylor should be alive today. Ahmaud Arbery should be alive today. Eric Garner should be alive today. Stephon Clark, Atatiana Jefferson, Sandra Bland—they should all be alive today. So it's up to us to carry on the fight."While most of those named by Philonise Floyd died while in police custody, Arbery was killed in a shooting by civilians. Three Georgia men, Travis McMichael, Gregory McMichael, and William "Roddie" Bryan were charged in connection with Arbery's death. His death came to light after it took 74 days before anyone was charged in connection with his death. Preceding Floyd at the virtual convention was Muriel Bowser, Washington D.C.’s Democratic mayor who called out President Donald Trump for using federal agents to deploy tear gas on a crowd of Black Lives Matter protests. During the height of the protests, federal agents used tear gas to disperse a crowd moments before Trump emerged from the White House to visit a burned out church across the street from the White House.“Where we were peacefully protesting, Donald Trump was plotting,” she said. “He stood in front of one of our most treasured houses of worship and held a Bible for a photo op. He sent troops in camouflage into our streets. He sent tear gas into the air—federal helicopters, too. I knew if he did this to D.C., he would do it to your city or your town.”During Bowser’s remarks, Trump’s campaign panned Bowser for saying she was “proud” of protesters. While Bowser wouldn’t initially commit to removing a “Defund the Police” mural from a D.C. street, city crews have since paved over the mural. 1967

As states across the country grapple with an increase in coronavirus cases and a huge demand for tests, many businesses are looking for other ways to get more mileage out of their supply chain.Like with anything else, supply and demand is a constant struggle. In this unprecedented era, the demand for things like coronavirus tests is so large that public health departments don't have a choice but to figure out ways to make our supplies last. Several states are examining pooled testing. California's Public Health Department says it's to "better leverage testing resources."Pooling is something that blood banks have used for decades to keep their blood supply safe. Dr. Claudia Cohn is the Chief Medical Officer of the AABB, formerly known as the American Association of Blood Banks.“If you have 100 people that need to be tested and if you test each of them, you’ll do 100 tests. If you find that your test is sensitive enough that you can pool together 20 samples at the same time, instead of having 100 tests, you can have five pools of 20,” Dr. Cohn said.Now, if one of those five pools is positive, then Dr. Cohn says, "You’ll need to break it out and test each of those separately. So, let’s say you have one positive person in a pool of 100 people, you either do 100 tests and find one positive or you do five pools of 20, four of those pools will be negative, so you’ve done 4 pools and covered 80 people."The test works by taking a tiny sample from each person who was tested.“When you take a swab from everyone’s nose, you isolate the DNA from that swab,” Dr. Cohn said about the PCR test, which is generally a nose swab. “It’s not a lot, it’s a small amount but it’s enough. Because these tests are very, very sensitive.”Those tests are so sensitive, and they have to be, that pooling can really only work if the test can handle, as in detect, multiple samples at once. The FDA mandates that.“The FDA is quite demanding as they should be in terms of making sure tests work well and are safe,” Dr. Cohn said.And Dr. Cohn says, pooling wouldn't work in an area where there's a large outbreak, which means a large number of people would test positive regardless of pooling. In the blood world, this strategy has been perfected.“You are taking 100 samples and taking a drop from each sample and putting it together,” Dr. Cohn said. “You are testing every single person who comes through. In the blood world safety is before everything."Blood banks test for HIV, Hepatitis C and B and well as COVID-19 antibodies, according to the American Red Cross. And, as this pandemic moves through our communities, Dr. Cohn says our blood supply needs to remain strong.“After that initial spike, it went down again and that was okay because elective surgery had been canceled, so the demand for blood had gone down as well so for a while we were at a good balance of demand and supply. But then elective surgeries opened up and hospitals went back to full service and we’re in a shortage again,” Dr. Cohn said. 3017
