In a few weeks, thousands of college students will begin their yearly right of fall by returning to the campus of Tufts University in Medford, Massachusetts, but a return to campus life this year will mean testing and quarantining for those students who chose to come back.Like colleges and universities across the country, Tufts is experimenting with a new plan that will allow more than 5,000 students to come back to campus while at the same time, instituting rigorous new guidelines in an effort to keep COVID-19 from spreading.The key to success, testing.“We wanted to test for COVID at a frequency that would catch people when they’re asymptomatic before they have a chance to spread,” explained Tuft’s President Anthony Monaco.Tufts plan for the fall is as complex as the virus itself. Students from outside the Northeast will be brought back to campus first, where they will be forced to quarantine for 14 days. Health officials expect at least a small portion of those students to test positive for COVID-19 the moment they step back on campus. Because of that, the university has constructed an extra 200 modular units of dorm space. The idea of the modular facilities is to give campus health officials a contained area to monitor students who test positive for the virus, while at the same time, keeping them out of the general population.After students from outside the Northeast are brought back to campus, students from the general area around New England will return.Every single student will be tested twice a week for COVID-19, something experts say will be a key component to safely reopening college campuses this fall. Regardless, school officials expect students to test positive for the virus throughout the fall.Researchers at Yale’s School of Public Health have been advising Tufts and hundreds of other colleges who are planning to resume some form of in-person learning this fall.“If we don’t test frequently, we give silent spreaders an opportunity to grab hold and this virus is hard to play catch-up with,” explained Professor A. David Paltiel, who recently published a study on how quickly the virus can spread through colleges if left unchecked.To study the virus, Paltiel and his colleagues used epidemic modeling to assemble hypothetical situations resembling a college campus. The study found that if you take 5,000 healthy students and add in only 10 students who have COVID-19, hundreds, if not thousands, of kids will be sick by Thanksgiving.“At that point, the only thing that keeps the virus from getting out of control is Thanksgiving break,” he said.That is why testing is key, the study found. When Paltiel took those same 5,000 kids and added in 10 students who have COVID-10, but tested every student twice a week, the study found that only about 100 students ended up catching COVID.“Many universities are planning to only test students who have symptoms, in our view that is a recipe for disaster,” he said.Only adding to the uncertainty of the situation, about 40 percent of college students said they would return to live near campus even if classes were held virtually. Paltiel and other health officials say because of that, it’s more beneficial to have students on-campus where they can be monitored and tested frequently.“It’s hard and it could be a nightmare, people who say we shouldn’t open campuses should remember the nightmare doesn’t go away,” he said. 3420

If someone asks to borrow your cellphone, would you lend it them? If you have a popular payment app on there, you might want to think twice.Popular money transfer apps and services like Venmo, PayPal or Apple Pay are all attached to people’s bank accounts.Brittany Burmeister uses Venmo every day. She wasn’t aware police in cities across the country are warning of a scam circulating, costing some thousands of dollars.It works like this: someone asks to use your smartphone, says their battery died or they left theirs at home, they use your payment app and steal your funds without you even knowing.Joseph Martinez, an information system security professor at Milwaukee Area Technical College, says when you’re not using them, log out of the money apps and while you’re at it, get off of Bluetooth.“They can hack into the phone via the Bluetooth portal and then through that portal have access to any application that you have your password and credentials automatically stored,” said Martinez.He also suggests linking your credit card instead of a debit card, so you have more protection. Burmeister is taking notes, considering her cell, like so many others, is a digital wallet. She says she’s not sure now if she’ll hand off her phone to a stranger. “I’d probably just say 'hey, I bet the restaurant has a phone inside' or if they’re in a public place,” said Martinez. A spokesperson for Milwaukee police hadn’t heard of any reports but urges people to be cautious. Martinez says as another precaution, you should download antivirus and spyware apps and what’s called a VPN app, or "virtual private network." It will shield your financial apps from strangers trying to gain access. 1726

In a critical situation where minutes determine life or death, you may think emergency medical services offer your best chance of survival. However, a Johns Hopkins trauma surgeon doesn't think that's always the case.“If it were me, and I know a lot about trauma, drive me to the trauma center as fast as you can,” said Dr. Elliott Haut, associate professor of surgery and emergency medicine at the Johns Hopkins University School of Medicine and senior author of a new study that evaluates emergency transport for shooting and stabbing victims.Haut and colleagues examined data from trauma centers within the 100 most populous U.S. metro areas and compared ambulance versus private vehicle transportation and the relationship between transport-mode and in-hospital mortality. He was not surprised by what he saw.“Patients who are injured with penetrating trauma — so stab wounds and gunshot wounds, in urban settings, so these are in the City — have improved outcomes and improved mortality if they're brought to the trauma center by private vehicle compared to emergency medical services, EMS,” Haut said.The keyword is trauma center; not all hospitals are equipped to handle walk-in patients with these kinds of injuries. And they are injuries that require immediate surgery. The study does not cover cardiac arrest where the most important thing is CPR and a defibrillator.“When we control for all those things, the rapid transport of patients by private vehicle makes a big difference,” Haut said.According to the study, 62 percent of patients are less likely to die when transported by private vehicle compared to EMS.Dr. Gabe Kelen has seen many of these walk-in patients at the Johns Hopkins Hospital emergency department.“You're waiting, waiting, waiting, the ambulance people get there, they do certain things, very skilled, it's all being done out there. Then they load you up, drive through traffic, they get here, that can take twice as long. It sometimes really is better to get you here, let us start doing our more definitive thing that we can do only in the emergency department,” said Kelen, director of the emergency department.He agrees time is of the essence, but also cautions that this is one study.“If you get multiple people being dropped off at one of the smaller hospitals, they may not have the staff to do everything that a place like ours can do so let the system work,” Kelen said.The current standard of care in Maryland is to wait for EMS to arrive. Dr. Richard Alcorta, acting co-executive director of the Maryland Institute for Emergency Medical Services System (MIEMSS), does not support changing the standard.He says not everyone knows where a trauma center is located and EMS can perform certain life-saving procedures that may be crucial before transport. A spokeswoman with the Baltimore Police Department said they do not have a position on the study’s findings and that “preservation of life is paramount." She added that a victim's decision to leave a crime scene "has little if any bearing on the outcome of the investigation. Thanks to video surveillance, CCTV cameras and our crime scene technicians it all seems to work out in the end.” For more information on the study, click here. 3283

If you feel like you're working more since you've started working from home, you're probably not wrong.A study by Atlassian found that since April, our workdays have become longer. That's around the time many people started working remotely.On average in the United States, people worked about 30 minutes more. People start work earlier and wrap up later.A separate report by LinkedIn found more than a quarter of people are checking in on work during off-work hours.However, this isn't necessarily leading us to be more productive. Often, we're working longer days because we're getting distracted while we're at home.“Everything's getting pretty mushy, so what that looks like is Netflix might be happening at 2 o’clock in the afternoon or you might be doing laundry at 11, instead of being fully focused on your work during the day, and I do think that is creating working longer hours,” said Elizabeth Grace Saunders, a time management coach.Saunders says there are additional distractions now.For instance, if you're a parent, your child may be learning from home. Sometimes you need to step in to help them, which can take time away from your work. That's completely okay, as long as we're still managing our time efficiently.Another thing that's changed is we may not necessarily have something to look forward to after work.Happy hours and going to the movie theater with a friend aren't really happening, so we may feel less motivated to work throughout the day.These longer work hours are giving us less of a chance to recharge for the next day, so it's important that we draw the line between work life and home life.Saunders says to pick a time where you only work... And don't do things like personal chores or take long breaks.“Those work hours are times when I’m devoted to work, and I’m really focused, and I’m not getting other things. That gives you the freedom and flexibility to feel like, I got work done today, I got done what I needed to get done and I need to do something refreshing or recharging at night.”We can still create things to look forward to after work, like having a time where we call friends and family, or plan to do something else you enjoy like crafting. 2204
