A recent study by the U.S. Centers for Disease Control and Prevention found that 6% of more than 3,000 health care workers who were tested had antibodies to coronavirus. Still, after being retested 60 days later, 28% of them had antibody levels so low they were no longer detected."These results suggest that serology testing at a single time point is likely to underestimate the number of persons with previous SARS-CoV-2 infection, and a negative serologic test result might not reliably exclude prior infection," the authors of the study said.According to the CDC, blood samples were taken from 3,248 frontline health care personnel at 13 hospitals between April 3- June 19, 2020.194 of those healthcare workers had detectable antibodies to COVID, the agency said.Participants with higher initial antibody responses were more likely to have antibodies detected at the follow-up test than were those who had a lower initial antibody response, the study concluded.The authors added that the study shows that the window is limited for collecting potentially useful "convalescent plasma" from the blood of patients who have fought off COVID-19. 1151

A member of the Proud Boys, a far-right group, is under arrest and facing nearly a dozen charges in Portland. The charges allege Alan Swinney pointed a revolver at counterprotesters and fired a paintball gun and mace at them on two separate occasions in August.Swinney, who is scheduled for a court appearance Thursday, was charged in a secret indictment Sept. 11 but not arrested until Wednesday.“In summary, the indictment alleges that Swinney used a paintball gun on August 15, 2020 to cause physical injury to another person,” the statement from the Multnomah County District Attorney’s office said.“Further, the indictment alleges that Swinney used a paintball gun on August 22, 2020 to once again cause physical injury to another person; that he also carried and then pointed a revolver at someone which placed that person in fear of imminent serious physical injury and that he unlawfully discharged mace or a similar substance toward another person.”Swinney remained in custody Wednesday and it wasn’t immediately clear if he had retained an attorney or would be assigned a public defender. 1106

A pair of districts in the Midwest will add Muslim women to the ranks of the US Congress for the first time.Michigan Democrat Rashida Tlaib and Ilhan Omar, the Minnesota Democratic-Farmer-Labor Party's nominee, will secure their respective seats in strongly Democratic districts following primary victories earlier this year that effectively decided their races.Tlaib is endorsed by the Democratic Socialists of America, a burgeoning left-wing group that also counts New York Democratic congressional nominee Alexandria Ocasio-Cortez among its members.Omar, in addition to being one of the first Muslim women in Congress, will also be the first Somali-American member. She came to the US more than two decades ago as a refugee. Tlaib actually campaigned with Omar ahead of the latter's primary race earlier this year.Omar also had the backing of Ocasio-Cortez in her primary race, and she will come to Congress having been an open critic of the Israeli government's treatment of Palestinians.Omar will take the seat vacated by Minnesota Rep. Keith Ellison, the first Muslim elected to Congress. Ellison is leaving Congress as he vies to become Minnesota attorney general.Tlaib will fill the seat formerly occupied by Michigan Democratic Rep. John Conyers, who left office last year amid accusations of sexual misconduct. She ran unopposed on the general election ballot following her primary win.Tlaib is the daughter of Palestinian immigrants and became the first Muslim female member of Michigan's state legislature a decade ago. A self-styled progressive, Tlaib is a vocal critic of President Donald Trump and was arrested two years ago for disrupting a Trump speech in Detroit.Only two other Muslims have been elected to Congress, and both are men currently in office: Ellison and Indiana Democratic Rep. Andre Carson. 1830

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 student at Island Park High School in Florida was suspended after the principal and other staff members saw him imitating a gun with his hands and pretending to shoot in a classroom.This happened Friday. "You shouldn't be doing something like that at all," former Island Park High School student Devan Hinton said."It's just not something to be taken lightly," Sam Sherman, who lives in Fort Myers, told Scripps station WFTX in Fort Myers, Florida.The principal called the Lee County Sheriff's Office to file an incident report after he saw the student "imitating a rifle with his hands and pointing it to the classroom."Another staff member described the student making "a gesture with his arm simulating as if he was firing a weapon into the classroom."A third staff member said the student "stood in the classroom doorway and made a machine gun style pose with his arms pretending to shoot at the classroom.""That isn't OK. With everything going on, that's not something to joke about. That's lives in someone's hands," Hinton said.The principal said he didn't think the student was serious but will not tolerate this behavior in school, so he suspended him.It's an action Sherman said he agrees with for the safety of the students."It's better to be preventative than wait and let it go on, and God forbid something else occur," he said.The principal of Island Park High School, Arthur Nauss, sent WFTX this statement:"I took the disciplinary action of sending the student home after I observed him pointing his finger at another student imitating that he was shooting a gun. The student pointing the finger and the student he was pointing at know each one another and were laughing at one another. There was no threat being issued but I believe it necessary to make it clear to the student, and all our students, that this is unacceptable behavior considering the recent events here in Florida. I called the student’s mother to inform her of what had occurred and let her know I would be working with the student in the future to ensure this behavior does not reoccur.When the student returns to school he will be informed that any future actions such as this one will result in a suspension or expulsion from school. I will also let him know that actions like this in the future will be reported to the appropriate authorities." 2379
