A software flaw is being blamed for showing a positive COVID-19 test result incorrectly for more than two dozen tests. University of Kentucky laboratory scientists say they were inspecting and reviewing raw data from a testing platform when they became concerned about discrepancies in the data. They believe the testing platform, Thermo Fisher, which was authorized for emergency use by the FDA, had a software flaw that might result in false positives.After re-testing the samples using another platform, scientists confirmed that the tests initially reported as positive for COVID-19 were negative. The flaw was only found in one of the four testing platforms that UK's clinical laboratory uses.Every patient who received incorrect results is being notified about the issue. No negative results changed. UK HealthCare also has notified Thermo Fisher Scientific and the FDA."For anyone tested at UK HealthCare, it is important to know that the vast majority of results have not changed," said UK Executive Vice President for Health Affairs Dr. Mark Newman. "Since these very astute employees discovered this issue, we have taken extensive measures to validate each test in question and worked diligently to contact all parties – the vendor, the FDA -- and most importantly, our patients and providers."UK HealthCare says they are working with local health departments and the Kentucky Department of Public Health to correct all data."UK's clinical laboratory has performed more than 30,000 COVID-19 tests since March and only a very small percentage of tests have been affected by this software defect," Newman said. "Anyone who has received test results and has not been contacted this week about re-testing, should be assured their result is correct."This story originally reported by Jordan Mickle on LEX18.com. 1825

A new study from Canada's Ottawa Hospital Research Institute found that marijuana use during pregnancy makes it 1.5 times more likely the child will develop autism.The findings will be published in journal Nature on Monday.The study followed 500,000 women and children between 2007 and 2012.In 2,200 cases, mothers said they used marijuana while pregnant, and never did other drugs, tobacco, or alcohol.The study found "an association between maternal cannabis use in pregnancy and the incidence of autism spectrum disorder in the offspring.""The incidence of autism spectrum disorder diagnosis was 4.00 per 1,000 person-years among children with exposure compared to 2.42 among unexposed children, and the fully adjusted hazard ratio was 1.51," the study showed. 771

A survey of parents across the United States estimates that one in 40 children has autism spectrum disorder, according to a study published Monday in the journal Pediatrics.In other words, the condition was reported in 2.5% of children, representing an estimated 1.5 million kids ages 3 to 17.A report released this year by the US Centers for Disease Control and Prevention estimated the prevalence at one in 59 children or about 1.7%, based on 2014 data."Prevalence is not growing that rapidly, although the CDC's data suggests it is still growing," Thomas Frazier, chief science officer of the advocacy organization Autism Speaks, said in an emailed statement. He was not involved in the new report."What is happening is that these studies use methods that are a bit more liberal and inclusive than the CDC's methods," Frazier said, adding that he prefers the CDC's numbers but understands "that they are likely a bit conservative."The new study is based on the 2016 National Survey of Children's Health, which was conducted by the US Census Bureau and which collected information from parents of more than 50,000 children up to age 17. To be included in the estimate, parents would have had to report that their child had ever received a diagnosis of autism spectrum disorder and that they currently had the condition.The new numbers were also slightly lower than those in the 2017 National Health Interview Survey. It estimated that 2.76% of children had ever received such a diagnosis, which the authors of the new report note is a broader definition.The fact that the new study relies on parental reporting -- which is not validated by health and education records, as in the CDC report -- may be a limitation despite the broad scope of the research, the authors say.Frazier said the 1-in-40 figure is "generally consistent with previous parent surveys and other direct prevalence studies where researchers directly screen for and attempt to identify autism."The parents in the new study also reported more difficulties getting the health care their children need, versus those with Down syndrome, or other behavioral disorder, such as attention-deficit hyperactivity disorder."Though we've seen progress in recent years, this confirms what we know from our parents -- that many children face unacceptable delays in getting a diagnostic evaluation, even after parents, teachers or other caregivers have recognized the signs of autism," Frazier said.In the new study, more than a quarter of children with autism spectrum disorder were taking medication for symptoms related to the condition, and nearly two-thirds have received "behavioral treatments" in the past year, the study says.It also found a higher prevalence for autism spectrum disorder among certain groups such as boys, children of single mothers and households below the federal poverty level, compared with those at least four times above that income threshold.The differences between the new study's numbers and those of the CDC study might be explained by the years they were conducted, the ages of children studied and where they lived, according to the new study.The CDC report was based on data collected from 11 communities across the country but was not necessarily nationally representative, according to that report's co-author Daisy Christensen, surveillance team lead in the developmental disabilities branch of the CDC's National Center on Birth Defects and Developmental Disabilities."Parents know their child best," Christensen, who was not involved in the new report, previously told CNN. "We want to encourage parents to be aware of their child's development, to be aware of the milestones that children achieve."Autism spectrum disorder, a lifelong developmental disability, is characterized by problems with communication and social interaction with accompanying repetitive behavior patterns.The authors note that it's difficult to compare the new report with prior iterations due to updates in how the survey collected its data and how questions were worded."We cannot tell what proportion was explained by internal survey changes rather than external factors," the authors wrote.Still, the report comes as estimated prevalences of the disorder have been rising for decades."Over the '80s and '90s, the diagnostic criteria expanded to include more children," Christensen said, "so I think that's definitely a possibility for the increase that we've seen."In the past, more than half of children identified with autism also had intellectual disability, and now it's about a third, she said. "And that's really consistent with identifying children who are perhaps at the milder end of the spectrum."The new study's authors also note that universal screening recommendations in the 2000s may have led to a rise in prevalence among younger children, for example."Because there is no biological marker, [autism spectrum disorder] is a particularly challenging condition to track," the authors note.But understanding how common it is allows health experts to distribute resources and get families the help they need, according to Frazier."Having prevalence estimates -- even if there is some variation -- helps us to advocate for improved screening, diagnosis, interventions and supports," he said. 5314

A swimmer died following an apparent shark attack near Bailey Island, Maine, on Monday, the Maine Department of Natural Resources confirmed.The agency said that kayakers brought the unidentified woman to shore after swimmers saw she was injured from an apparent shark attack. She was pronounced dead at the scene by EMS responders.Swimmers and boaters in the area were being told to remain cautious following the attack.The University of Florida, which has a database of shark attacks in the United States, has not reported any such attacks from 2010 through 2019 off the coast of Maine. On average, there are 45 shark attacks in the United States a year. But fatal shark attacks are very rare in the US – just seven reported fatalities in the last decade, and three in the last four years.According to the University of Florida, there was a fatal shark attack off the coast of California in May, marking the first US shark attack death in nearly two years. 965

A non-profit organization announced its come up with a way to feed voters at several polling places across the nation for free on Election Day.World Central Kitchen kicked off their initiative last week with the announcement of its #ChefsforthePolls.They say people often cast their vote before work, during their lunch break, or after work, and those are the same time's people typically grab something to eat.And with long lines at polling stations, that could be the difference between voting and not voting, so they want to help make it a convenient experience for voters."WCK and our partners are activating #ChefsForThePolls to serve nourishing meals on early voting days and Election Day," the organization said on its website. "We'll be stationed by polling locations around the country, targeting those with historically long lines, predicted massive turnouts, or limited facilities, sharing meals with anyone – no questions asked. If we can help alleviate the challenges of Election Day, we will be there."The organization said it'll pair up with local food trucks and restaurants for the meals.WCF said their effort has nothing to do with politics, and they "will feed people of all political parties and beliefs."They would serve food in Miami, Los Angeles, Atlanta, Detroit, Phoenix, Chicago, Portland, and other major cities.You can see the rest of the locations by clicking here. 1402
