As the coronavirus pandemic continues, doctors are learning more about the damage having Covid-19 can do to the body. Two separate studies published recently indicate the coronavirus can harm other organs in the body, including the heart.One of the studies looked at 100 patients in Germany who recently recovered from Covid-19 and found 60 percent of participants had inflammation in the heart. The study used MRI scans to monitor the inflammation, and was published in JAMA Cardiology.The majority of the patients in this study, 67 of them, recovered from the coronavirus at home with severity ranging from asymptomatic to moderate. It compared the MRIs of coronavirus survivors to scans from healthy volunteers.The data showed there was some sort of heart involvement in those who had coronavirus, whether or not they had preexisting conditions or any heart-related symptoms during recovery.“Our findings reveal that significant cardiac involvement occurs independently of the severity of original presentation and persists beyond the period of acute presentation, with no significant trend toward reduction of imaging or serological findings during the recovery period. Our findings may provide an indication of potentially considerable burden of inflammatory disease in large and growing parts of the population and urgently require confirmation in a larger cohort,” the researchers noted in conclusion.A second study, also published in JAMA Cardiology, found coronavirus could be found in the heart tissue of patients who died.The study looked at data from 39 autopsy cases in Germany in early April. The patients were aged 78 to 89, had tested positive for Covid-19 and there were results of heart tissue analysis in their autopsies.In 16 of the 39 cases, there was a large “virus load” of coronavirus found in the heart tissue, another eight had a coronavirus presence in the tissue.The sample of autopsy cases was small and the "elderly age of the patients might have influenced the results," the researchers wrote. More research is needed whether similar findings would emerge among a younger group of patients."Taken together the studies support that SARS-CoV-2 does not have to cause clinical myocarditis in order to find the virus in large numbers and the inflammatory response in myocardial tissue. In other words, one can have no or mild symptoms of heart involvement in order to actually cause damage," said Dr. Dave Montgomery, who was not involved in the studies, in a statement to CNN.Dr. Clyde Yancy of Northwestern University Feinberg School of Medicine and Dr. Gregg Fonarow of the University of California, Los Angeles, co-authored an editorial that accompanied the two new studies in the journal JAMA Cardiology called ‘Coronavirus Disease 2019 (COVID-19) and the Heart—Is Heart Failure the Next Chapter?”“We see the plot thickening and we are inclined to raise a new and very evident concern that cardiomyopathy and heart failure related to COVID-19 may potentially evolve as the natural history of this infection becomes clearer,” they write. 3076

At least eight members of the same family were among the 26 people killed Sunday when a man armed with a rifle burst into the sanctuary of a church in Texas and started firing.The mass shooting left about 20 others wounded at the First Baptist Church in Sutherland Springs, about 30 miles east of San Antonio.The massacre killed about 4% of the small town's population. And no one at the church was left unscathed, Wilson County Sheriff Joe Tackitt said."I think nearly everyone had some type of injury," the sheriff told reporters Monday.Texas Gov. Greg Abbott called the slaughter "the largest mass shooting" in the state's history. But it's still unclear what motivated the killer.Latest developments-- The killer had in-laws who attended the church, but they were not present at the time of the massacre, the sheriff said.-- The shooter was first shot by an armed resident who confronted the gunman outside the church. The suspect then turned the gun on himself, authorities said. He was dressed in all-black tactical gear, including a ballistic vest, and was later found dead in his vehicle.-- The victims ranged in age from 5 to 72 years old, said Freeman Martin, a regional director with the Texas Department of Public Safety. The visiting pastor was among those killed, Tackitt said.-- The 14-year-old daughter of the church's regular pastor was among those killed, said Sherri Pomeroy, the girl's mother. Her parents were traveling out of state when the shooting occurred.-- At least eight of the people killed were members of one family, according to a relative and a community leader. Those relatives span three generations and include a woman who was about five months pregnant and three of her children.-- A witness told CNN affiliate KSAT that he and the armed resident pursued the gunman in a car chase for about 11 miles.-- Speaking from Japan, President Donald Trump expressed condolences for the victims during a Monday news conference and said he believes the shooting was caused by a "mental health problem," not an issue with US gun laws.Who was the shooter?The gunman has been identified as 26-year-old Devin Patrick Kelley, according to two law enforcement sources who have been briefed on the investigation.But police have not officially named Kelley as the shooter. They described the gunman as a white man in his 20s. Authorities have not said what the motive was.Kelley was a member of the US Air Force and served at Holloman Air Force Base in New Mexico from 2010 until his discharge, according to Air Force spokeswoman Ann Stefanek.He was court-martialed in 2012 for assault on his spouse and assault on their child, according to Stefanek. He served a year in confinement, received a bad conduct discharge and had his rank reduced, she said.In April 2016, Kelley purchased the Ruger AR-556 rifle he allegedly used in the shooting from a store in San Antonio, Texas, a law enforcement official said. There was no disqualifying information in the background check conducted as required for the purchase, a law enforcement official told CNN.At one point, the shooter tried to get a license to carry a gun in Texas but was denied by the state, Abbott said, citing the director of Texas' Department of Public Safety."So how was it that he was able to get a gun? By all the facts that we seem to know, he was not supposed to have access to a gun," Abbott said. "So how did this happen?"How the attack unfoldedThe gunman was first spotted at a Valero gas station across the street from the church at about 11:20 a.m. (12:20 p.m. ET).He drove across the street, got out and began firing even before he entered the church, Martin said.David Flores told CNN that his father saw the shooter."My dad saw the gunman run into the church building and then he heard shots and saw people running," Flores told CNN. "People covered in blood and screaming. It was pandemonium everywhere."As the shooter left the church, a local resident used his own rifle to engage him, Martin said. The gunman dropped his weapon and fled.Johnnie Langendorff said he was driving to his girlfriend's house when he saw the shootout between the shooter and the armed resident.The gunman took off in a Ford Explorer, Langendorff told CNN affiliate KSAT.The resident "briefed me quickly on what had just happened and said we had to get him, and so that's what I did," Langendorff said.They gave chase in his truck and called police. As they sped after him, Langendorff said, the shooter "eventually lost control on his own and went off into the ditch" in neighboring Guadalupe County."The gentleman that was with me got out and rested his rifle on my hood and kept it aimed at him [shooter], telling him to get out. There was no movement, there was none of that. I just know his brake lights were going on and off, so he might've been unconscious from the crash or something like that. I'm not sure."Law enforcement later found the suspect dead of a gunshot wound inside his vehicle.A law enforcement official briefed on the investigation said multiple weapons were found in the shooter's car. The FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives are involved in the investigation.The victims and griefHours after the shooting, residents of Sutherland Springs hugged one another, held candles and sang hymns in a vigil Sunday night. Abbott attended the event, in which faith leaders offered words of solace and prayers.Sutherland Springs is the kind of place where "everybody knows everybody," said Gloria Rodriguez Ximenez, who attended the vigil."This is a small, Christian town, a very small community," she said. "Everybody's united. Everybody's so close to everybody."She knows the First Baptist Church's pastor and his family, including their daughter who died."I can feel the pain everybody's going through. There's so much hurt for a small town," Ximenez said.Others echoed the feeling of shock and heartache."My heart is broken," Wilson County Commissioner Albert Gamez Jr. told CNN. "We never think where it can happen, and it does happen. It doesn't matter where you're at. In a small community, real quiet and everything, and look at this."Twenty-three people died inside the church, which has a small sanctuary with wooden pews and red carpeting. Two died outside the church, and one at the hospital.The wounded are being treated at three hospitals including the Connally Memorial Medical Center in Floresville, University Hospital and Brooke Army Medical Center in San Antonio.The-CNN-Wire 6515

  

BALTIMORE — Scammers are using the COVID-19 pandemic and financial crisis to take advantage of unemployed workers.Like millions of others, Daniel Martin recently lost his job, but he caught a break with a new company.“I was really excited. It sounded like a really good position with a lot of possibilities of growth within the company. It just seemed like something I was looking for,” said Martin.He received a contract and was assigned a project. The company, Gap Systems LLC, was moving their offices to Baltimore and needed him to procure new equipment. Since he wasn’t full-time just yet, he’d have to purchase the laptops with his credit card and the company would reimburse him.“The next two weeks, I completed a total of three purchase orders and all of the payments were posting perfectly fine,” Martin said.A few weeks later, the charges suddenly reversed and Martin’s credit card balance exceeded ,000.After speaking with a bank representative, he learned the account owner had reported the charges as fraudulent.“They probably in some other way scammed someone else to get their account and routing number and then they gave me that information to pay my credit card,” said Martin.Martin feels he should’ve known better, but his excitement clouded his judgment. And this is happening to job hunters around the country. According to the Federal Trade Commission, consumers reported losing 0 million to these scams in the first nine months of 2020.This week, the FTC along with 19 federal, state, and local law enforcement partners, announced a crackdown on scams targeting consumers with fake promises of income and financial independence.More than 50 enforcement actions were taken against operators of work-from-home and employment scams, pyramid schemes, investment scams, bogus coaching courses, and other schemes.“If at any point during any part of the process they ask you to buy anything, just don’t,” said Martin.Especially with checks. It’ll likely bounce then you’re on the hook for that money.And if someone contacts you about a j

  

BALTIMORE - Food safety experts are warning parents to be mindful when packing perishables like sandwiches and yogurts in your child's lunch.Tanya Brown with the United States Department of Agriculture (USDA) said you're looking at a two-hour window before those brown bag lunches become breeding grounds for bacteria.“You should not put perishable items like bologna sandwiches, turkey sandwiches, cheese or yogurt in a brown paper bag and send a child to school with it,” Brown said.Foods can hit the "danger zone," or temperatures between 40-140 degrees Fahrenheit, when it’s left out of refrigeration over two hours. After four hours, the food item should be tossed.“You want to make sure you put them in an insulated lunch bag with at least two cold sources and those two cold sources could be a frozen water bottle or frozen juice packs or gel packs in there. So, you want to put those perishable items in there and make sure the child does not open the bag and keep opening and closing the bag before lunchtime,” said Brown.If you're sending them with something hot, use a thermos, and warm it up first.“The best way to prepare it is to pour boiling hot water into the thermos first, then discard the hot water and then put the hot soup or stew in there. Make sure it's at 165 degrees Fahrenheit,” Brown said.However, the leading cause of sickness is poor hand washing. Brown said this is an easy problem to solve:“Oftentimes, children don't get an opportunity to wash their hands before they go to lunch and just to trigger their memory put a moist toilette in there or some hand sanitizer to remind them before they start to eat their lunch,” she said.Click here for more information on the danger zone and safe handling of food. 1751
