As of Tuesday, Petco says they no longer sell electronic "shock" collars and have removed them from its shelves and website.The company said they stopped selling the human- and bark-activated electronic pet collars in a press release on Tuesday because they wanted to strengthen their commitment to positive reinforcement training methods. They also wanted to solidify their evolution from "a leading pet specialty retailer to a category-defining health and wellness partner" for animals and their owners."Electricity may be critical to powering your microwave, but it has no role for the average pet parent training their dog," said Petco CEO Ron Coughlin in the press release. "Shock collars have been shown to increase fear, anxiety, and stress in dogs, and we believe there's a better way – Positive Reinforcement Training."The San Diego-based company is also calling on the pet industry and consumers to join in its newly launched "Stop the Shock" online campaign that will create "responsible regulation for the retail sale of shock collars to general consumers."Along with today's announcement, Petco also launched a new look declaring itself "Petco, The Health + Wellness Co." to reflect how they've evolved into a health and wellness company."As a health and wellness company, our mission is focused on improving pet lives, and we think selling shock collars does the opposite," Coughlin said in the news release. "It's our responsibility to ensure that we, and others, aren't putting potentially harmful products in the wrong hands." 1551

As the COVID-19 pandemic progresses, researchers say it is important to track how the coronavirus mutates because it could affect the efficacy of a vaccine.Like all living cells, viruses evolve their chemical make-up changes. In viruses like the flu, that happens frequently, which is why every year there is a new vaccine to treat whatever strain is expected to circulate. With COVID-19, however, those mutations happen much slower, according to research out of Arizona State University.“One of the things we’re still keeping an eye on is the evolution of this virus because that virus is still around in the community,” said Dr. Efrem Lim, an assistant professor at ASU. “Everyone is coming in blind to this. This is a novel virus. This isn’t something we have seen before.”In March, Arizona State University played host to our country’s fourth COVID-19 case. As soon as it was detected, Dr. Lim started studying how the virus mutates and sent his findings to the World Health Organization. It's something that still continues to this day.“This virus, overall, mutates pretty slowly, which is a good thing,” said Dr. Lim. “However, we can have instances where the virus can have very large, dramatic, mutations, such as deletions in the genome.”While rare, Dr. Lim says those mutations can be significant as it changes how the virus acts inside the body.Currently, scientists are focusing much of their efforts on identifying ways to eliminate the function of the spike protein in COVID-19, as it is the way the virus binds to our cells and infects them (spike proteins are the stalks that protrude from the center of the virus that make it so recognizable).“It is very good news that the virus is not changing rapidly,” said ASU virologist Dr. Brenda Hogue. “We will have to see over time, as the virus continues to circulate, as we put a vaccine into play, whether or not there will be any issues.”Dr. Lim says right now there does not appear to be any issues because the virus mutates slowly, but he adds it could adapt to a vaccine once one begins to circulate.He says more testing needs to be done to determine that, however. 2140

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

As she watches her three boys play in the backyard, Acacia Clark can’t help but be consumed by an overwhelming sense of anxiety as she thinks ahead to the coming school year.It’s been a long four months for Clark and her husband, who are both trying to juggle full-time jobs, while at the same time, raise their young kids who haven’t been inside a classroom since March.“My focus on my work has been abysmal,” Clark said, as one of her 6-year-old twin boys asks her for a popsicle. “I’ll get in a few minutes here or there, but it’s been very stressful.”The COVID-19 outbreak meant schools in Newton, Massachusetts, where this family resides, had to be shut down. Across the country, school districts are carefully weighing their options about reopening in the middle of a pandemic.Clark wants her children to have the daily structure of school back in their lives. However, she's also incredibly concerned about someone in her family catching the virus.“What if one of us gets sick? That means the whole house would get sick. Then, how do we work?” she wondered.That is the reality facing countless families across the country.“It’s more than being stuck between a rock and a hard place, it’s just being stuck in a hard place constantly and not having a light at the end of the tunnel,” she added.Families are now having to juggle it all, while at the same time, making sure their kids don’t fall through the cracks.As some school resume in-person learning, many parents like Clark are worried about what could happen if there’s a sudden outbreak and their child’s school is forced to shut down.“I can either work or be there for me kids; I can’t do both,” she said.Recognizing the impossible predicament the pandemic has placed parents in, Congress passed the Families First Coronavirus Response Act back in March. It gives parents two weeks of paid sick leave if you find yourself having to quarantine. Parents also get two weeks of paid sick leave at two-thirds of their regular salary if the child's school or daycare shuts down because of COVID-19. Additionally, it guarantees 10 weeks of leave at two-thirds of their salary if they need to take care of a sick child.But those benefits will run out on December 31.“Employers are recognizing that there has to be a solution. If kids can’t go back to school, parents can’t go back to work full-time,” explained Chris Feudo, an attorney with Foley Hoag in Boston.As the pandemic enters its fifth month in the United States, Feudo says another issue facing parents is that they’ve already exhausted all of their FMLA leave. Because of that, he says parents should talk to their employers as soon as possible if it appears your child’s school or daycare might shut down because of a COVID-19 outbreak.“Come up with a plan and say, ‘This is the most I can do for my employer.’ If you have a thought-out plan, it shows you're being proactive and I think employers will be more responsive to that,” he added.Feudo says if you've run out of FMLA leave and need to ask your boss for more time off to care for family members, it's best to have the conversation in-person, if possible, or via a Zoom or video conference call. He says employers are being more flexible right now because of the outbreak but they need to see that employees are willing to bring up difficult situations before they become major issues.Under federal law, it’s also illegal for employers to retaliate against someone for using FMLA leave.As for Clark, she’s still waiting to find out if her district will have in-person learning this fall and she’s doing her best to manage whatever new challenge the pandemic throws her way.“I don’t know single parents are doing it, especially if they’re trying to bring in a paycheck,” she said. 3762

As someone who once criticized President Barack Obama for offering public timelines on American military engagement overseas, US President Donald Trump may have backed himself into a corner following his own promise to respond, and respond harshly, to the deadly chemical attacks in Syria.Last week he declared he wanted to withdraw US troops from Syria as soon as possible. But the suspected use of chemical weapons in Syria over the weekend may force him to reevaluate the US mission in that country.Vowing on Monday to come to a decision "over the next 24 to 48 hours" on how to make Syria pay a "big price," Trump's White House now appears to be scrambling to match its policy to his words.Trump tweeted Wednesday that missiles "are coming" in response to a threat from Russia to shoot down missiles coming into Syria.  836
