While public health experts have acknowledged the risk for healthy athletes when becoming infected with the coronavirus has been rather low, lingering questions have remained on if the virus causes long-term cardiac damage.Doctors from the Sports and Exercise Cardiology Section of the American College of Cardiology released some of their preliminary findings on the effect the coronavirus has on athletes’ hearts.With college football fully resuming this week with the return of the Pac-12, and college basketball slated to get underway next month, sports are beginning to return to normal amid the pandemic. While some athletes are being frequently tested for the virus, testing alone has not stopped team-wide outbreaks from occurring.Despite there being some limited evidence that the virus causes cardiac injury to athletes, researchers wrote in JAMA that heart damage alone should not be the primary reason to postpone athletic competitions amid the pandemic.“While concerns about the implications of cardiac injury attributable to COVID-19 infection deserve further study, they should not constitute a primary justification for the cancellation or postponement of sports,” the researchers wrote.“Rather than canceling sports because of unsubstantiated concerns about cardiac safety based on limited data of unestablished clinical relevance, this decision should be driven by the need to limit viral spread,” researchers added. “With uncontrolled community transmission, we share concerns with public health officials about risks of increased disease transmission attributable to the resumption of organized sports. Accordingly, the decision to proceed with or delay organized sports should be based on community disease prevalence, coupled with the availability of resources that can be responsibly allocated to identify and prevent new infections among athletes.”The researchers said that initial findings have produced only a handful of cases of cardiac injury, but stressed that more research is needed.“Reports of presumptive myocarditis among several athletes with high profiles have magnified concerns about COVID-19 CV sequelae in athletes,” the researchers wrote. “Our combined experience suggests that most athletes with COVID-19 are asymptomatic to mildly ill, and to date, (return to play) risk stratification has yielded few cases of relevant cardiac pathology. However, we underscore that these observations may not reflect the true prevalence and attendant prognosis of COVID-19 CV involvement in athletes.”As far as what players should do following their 10-day isolation period, assuming they minimal coronavirus symptoms?“We do not advocate for (cardiovascular) risk stratification among athletes who remain completely asymptomatic with prior COVID-19 infection, following completion of US Centers for Disease Control and Prevention (CDC) guided self-isolation,” the researchers wrote. “Given the current lack of published data, consideration of comprehensive screening for this population could be reasonable if it is based on research and data collection.”The Big Ten, which was among several leagues that held out on playing at the start of the football season, requires athletes to undergo cardiovascular screening following a positive coronavirus test. Part of what concerned the Big Ten initially was reports that a number of its athletes who tested positive for the virus had shown myocarditis symptoms.According to the National Institutes of Health, myocarditis is an acute injury that “leads to myocyte damage, which in turn activates the innate and humeral immune system, leading to severe inflammation.”“All COVID-19 positive student-athletes will have to undergo comprehensive cardiac testing to include labs and biomarkers, ECG, Echocardiogram and a Cardiac MRI,” the Big Ten said in a statement. “Following cardiac evaluation, student-athletes must receive clearance from a cardiologist designated by the university for the primary purpose of cardiac clearance for COVID-19 positive student-athletes. The earliest a student-athlete can return to game competition is 21 days following a COVID-19 positive diagnosis. “In addition to the medical protocols approved, the 14 Big Ten institutions will establish a cardiac registry in an effort to examine the effects on COVID-19 positive student-athletes. The registry and associated data will attempt to answer many of the unknowns regarding the cardiac manifestations in COVID-19 positive elite athletes.”To read an abstract of the research, click here. 4546

We've all heard exercise helps you live longer. But a new study goes one step further, finding that a sedentary lifestyle is worse for your health than smoking, diabetes and heart disease.Dr. Wael Jaber, a cardiologist at the Cleveland Clinic and senior author of the study, called the results "extremely surprising.""Being unfit on a treadmill or in an exercise stress test has a worse prognosis, as far as death, than being hypertensive, being diabetic or being a current smoker," Jaber told CNN. "We've never seen something as pronounced as this and as objective as this."Jaber said researchers must now convey the risks to the general population that "being unfit should be considered as strong of a risk factor as hypertension, diabetes and smoking -- if not stronger than all of them." 799

WEST PALM BEACH, Florida — West Palm Beach says the number of police cars that had to be pulled off the streets due to engine failure has risen to 49.City Administrator Jeff Green said at this point they believe a tainted fuel shipment in the middle of March is to blame. All of those cars had traces of biodiesel in their tanks, which are meant for unleaded only.West Palm Beach Police Public Information Officer David Lefont said it is not impacting public safety since the agency is supplementing with rental cars.“We have captains driving around in minivans,” Lefont said.Seventeen patrol cars have gotten new engines and are back in service.The other affected cars are non-marked cars.Green said Miami-Dade County police reported they had to pull 120 cars with the same issue.In West Palm Beach the cars affected are all Ford, which is why the automaker is investigating the case as well.But Green said at this point they believe it was the fuel shipment. They’re currently investigating where the shipment came from. 1035

With a majority of public school districts offering remote learning this fall, parents and teachers are ramping up online educational tools and resources for kids. Many are also focusing just as much on kids' mental health."It's going to be so much harder to build those relationships while you're on a virtual platform. What are we doing to start the year off with expectations of what students should do and how are they going to react with each other?" said Dr. Christina Conolly, a school psychologist in Maryland and a member of the National Association of School Psychologists. Dr. Conolly says with so many children missing that social interaction this fall, it's important for educators and parents to be intentional when it comes to keeping an eye on students' mental health."Anything we can do to help students engage with each other, bring a socialized setting that is supervised, is great," said Dr. Conolly. Before the COVID-19 pandemic, Dr. Conolly, like other parents, put major restrictions on screen time. Now, she says many of those limitations have gone out the window. Speaking about her own daughter, she says safe, online interaction is crucial to children's social development. "Right now, if she's on there spending a couple hours gaming with my neighbors because she can't go outside and play with my neighbors, well I'm like 'OK, it's helping her with her emotional health.' Because human beings need human interaction," said Dr. Conolly.Child suicide rates are up nationwide and calls into the National Suicide Prevention hotlines are skyrocketing, Dr. Conolly said. Many children who didn't have mental health struggles before the pandemic are finding themselves coping with them now and those who already had difficulties are getting worse. She has advice for parents who are concerned about their children getting depressed because of a lack of social interaction. "I would say a number of things. First, talk to the staff at your school. You can talk to the teacher, administration, psychologist or counselor in the building. If you're concerned, they can talk with your student," said Dr. Conolly.Teressa Ruspi is a parent of three and runs the LRJ Foundation, a mental health and wellness organization that partners with schools in Georgia, Virginia and Pennsylvania to teach kids about the importance of social emotional health. Ruspi is putting her own children's mental health at the top of her mind as her three head back to school virtually."I'm really trying to hone in and be really mindful of their emotions right now and what's triggering those emotions. How to balance those emotions, how to have those conversations with them, so they can feel comfortable talking to me about what's frustrating with them," said Ruspi. Ruspi says her kids are FaceTiming frequently with classmates and even doing occasional playdates with families who are taking similar precautions from COVID-19 as they are."Kids can get kind of complacent and used to their new surroundings so now that they have been removed and been remote and disconnected a lot, we want to make sure that they don't stay disconnected," Ruspi said.The good news, is that now that school is back in session, many parents will have access to free sessions with a school psychologist or counselor. An extra resource that could be an extra boost to keeping children happy and mentally healthy during virtual schooling. 3421
