Colleges are trying to figure out how students can safely get back to school, as more schools are choosing to go online only for the fall.For colleges that will have students on-campus, a big question is how testing could work. This week, Maryland's state universities are some of the latest to say they will test students if they can't prove they had a negative test within 14 days of arriving on-campusResearchers from Yale, Harvard and Massachusetts General Hospital have a model of what they say needs to happen for campuses to reopen.It includes testing students every two days along with strict social distancing measures“There are still schools out there who think they can get by with symptom-based monitoring,” said David Paltiel of Yale Public Health. “That is waiting until a student develops symptoms before springing into action. We have run simulations and scenarios over and over again. We have yet to find a single one where that is good enough.”Experts believe screening frequency is more important than test accuracy. But they say daily testing could lead to false positives. They think testing every two days will cost 0 per student per semester.“Any school that cannot see how it's going to reasonably implement a program of frequent screening alongside a program of social distancing really has to ask itself if it has any business reopening,” Paltiel said.Vassar College President Elizabeth Bradley looked at how the model would work for them. She wrote in the journal JAMA they would have a controllable number of infections, even if they only tested students every four weeks.They would also use social distancing, masks, and contact tracing. Students would need a negative COVID-19 test before they move in. 1743

COVID-19’s disproportionate impact on people living with diabetes is a growing concern.The American Diabetes Association says nearly 40% of COVID-19 deaths have been from those with the disease, while 90% of the hospitalizations have been people with diabetes or other underlying conditions.“Diabetes was a health crisis and epidemic in this country before the pandemic, and what the pandemic has done really is shine a very bright light on an old problem,” said Tracey Brown, CEO of the American Diabetes Association.Brown has lived with diabetes for 16 years. She's worried about additional financial struggles brought on by the pandemic.Even before COVID-19, one in four people were rationing their insulin to get by.Brown says the current unemployment rate is higher among people with diabetes. So, the burden has only worsened for those that have lost health coverage because of job loss.The disease also disproportionately impacts people of color living in low income areas.Brown says even now in 2020, every 5 minutes, someone in the U.S. loses a limb because of complications from diabetes.“There are so many comorbidities that go along with this, which is another reason why I talk about the fact that if we want to address the wellbeing of Americans, and improve the wellbeing of Americans, you can't have that conversation without having a conversation about improving diabetes,” said Brown.Brown wants to make sure people with diabetes don't feel like they're alone right now.There's a page of resources available on their website, Diabetes.org. You can also call 1-800-diabetes if you're struggling. 1620

CINCINNATI -- You've read these stories. We've even run some of them. They go like this: A police officer or paramedic touches a mysterious, powder-like substance during a drug arrest or attempted overdose revival, and their heart begins to hammer. Their sweat glands kick into overdrive. Their breath turns thick inside their lungs.After they're rushed to the hospital or dosed with naloxone on-scene, they recover. Their department usually invokes opioids such as fentanyl in explaining the possible incident; the phrase "accidental overdose" comes up.There's just one problem: According to the American College of Medical Toxicology and other medical sources, including Slate contributor Dr. Jeremy Faust, it's essentially impossible to overdose on fentanyl through skin contact alone."These drugs are not absorbed well enough through the skin to cause sickness from incidental contact," the ACMT wrote in a 2017 news release shortly after East Liverpool, Ohio police reported an officer had overdosed after brushing white powder from an earlier drug arrest off his shirt bare-handed. "Toxicity cannot occur from simply being in proximity of the drug. In the event drug powder gets on skin, ACMT recommends simply washing it off."Despite that statement, similar stories surfaced in Ohio during August and November 2017. More recently, news outlets in Texas reported a Houston officer had become ill and received a dose of naloxone after a drug bust in July. Days later, Harris County authorities announced there hadn't actually been any fentanyl at the scene.So what's the truth? According to Chad Sabora, a recovering drug user who founded the Missouri Network for Opiate Reform and Recovery, and neuroscience-pharmacology PhD Sarah Sottile, most of these officers are probably experiencing psychosomatic symptoms — maybe even panic attacks. It's highly unlikely they're actually overdosing on small amounts of fentanyl through skin contact.To illustrate this, Sabora and Sottile posted a video to Facebook in which Sabora safely holds a small amount of powder fentanyl in his bare hand while Sottile explains fear, not fentanyl, is the likely causes of police officers' symptoms. (Dr. Faust put it somewhat more bluntly in an opinion piece about the video, describing the incidents as "local authorities peddling what amount to ghost stories masquerading as true tales from the front lines.")"What scares me is that, if we don't dispel these rumors, kids will be left to die because an officer or first responder will show up on the scene, they'll believe that it's fentanyl there, and they will not attempt to save the person's life because of these fears," Sabora says in the video. "At the end of the day, we need to save these kids' lives, and we can't not go resuscitate out of fear."Newtown Police Chief Tom Synan had spoken to Scripps station WCPO in Cincinnati before in incidents of unconfirmed police exposure to opioids. He said Friday night he could not argue with the stances taken by doctors but still wanted to stress extreme caution among first responders dealing with potential opiates."I'm not one to dispute science," he said. "How do you dispute science? … I think the best way to look at this is that this issue is difficult. There are no easy answers with this. We have to err on the side of caution, not on the side of panic."It's not so dangerous that everyone that gets near it will be overdosing and dying," he added. "(But) continue to be careful. Continue to be cautious." 3523

  

CLEVELAND — Three suspects were arrested after an officer was shot and killed in Cleveland's Stockyard neighborhood Thursday evening.The unidentified suspects was arrested Friday morning.The shooting occurred around 10 p.m. in the 3200 block of West 65th Street near Storer Avenue, police said.The officer, later identified as Det. James Skernivitz, was rushed to MetroHealth Medical Center where he died from his injuries, according to the Cleveland Police Patrolmen's Association.Police said another person was confirmed dead on the scene but was not a suspect.Skernivitz's identity was held pending the notification of his family, as he is married with children, police said.Cleveland Police Patrolmen's Association said Skernivitz has been on the force for "a while," was "well-liked" and was a "good man.""This one hurts," Cleveland Police Patrolmen's Association president Jeff Follmer said.Skernivitz was a 25-year veteran of the Cleveland Division of Police, authorities said."We definitely need the prayers of the people in the city. This officer was out doing what all police officers do — trying to protect the people the city — and he gave his life, so we ask that you kind of give his family a little room," Cleveland Police Chief Calvin Williams said.Special agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) in Columbus responded to the scene to assist police.This story was originally published by Camryn Justice on WEWS in Cleveland. 1482

  

CVS and Walgreens are gearing up to give coronavirus vaccines - in long-term care facilities, not retail stores - once the FDA approves one for emergency use.According to CNN, CVS would administer the shots by mid-December, and Walgreens plans to start distributing within days of receiving them.In October, the U.S. Department of Health and Human Services (HHS) announced agreements with both companies to give vaccinations to long-term care facility residents nationwide with no out-of-pocket costs.According to the HHS, both companies will schedule and coordinate on-site clinic date(s) directly with each facility.The HHS said that residents and staff would likely need three total visits over two months to be given both vaccine doses."CVS Health has been on the frontlines of the fight against COVID-19, working across the health care spectrum in all the communities we serve, and that will continue to be the case when we have a vaccine to dispense," said Troy Brennan, Chief Medical Officer, CVS Health in a press release.On Tuesday, the CDC's Advisory Committee for Immunization Practices is having an emergency meeting, which will take place from 2-5 p.m. ET, to vote on who they recommend should be the first in the U.S. to get vaccinated once one is authorized. 1281
