A Russian woman who needed surgery to address ovarian cysts was given Fedyaeva formalin, a solution that contains formaldehyde, which is used to preserve bodies, Russian state media organization RT reported.Ekaterina Fedyaeva, 28, was told by doctors the procedure would be routine. Little did she know it know that the laparoscopic procedure to remove the cysts would kill her. Fedyaeva was supposed to be given saline solution, but instead was given the formaldehyde-type solution. Fedyaeva then complained to her mother, saying that she was "dying."It turns out she was right. Doctors tried to wash her abdominal cavity of the formaldehyde.Her organs began failing. In response, doctors tried to keep her alive, but she died last Thursday. Russia's minister of health, family and social well-being Rashid Abdullov said, "I express my sincere condolences to the relatives and relatives of Catherine Fedjaevoj. It's a big tragedy! We will provide all the necessary assistance to the family. All the guilty officials have already been held accountable, the investigating authorities continue to work."It is unclear how doctors mixed up the two solutions. Authorities in Russia have opened a criminal investigation into the surgery.   1341

A recent study published Wednesday in the New England Journal of Medicine suggests that antibodies might protect people who've already had COVID-19 from being reinfected for at least six months.Researchers looked at 12,541 healthcare workers at Oxford University Hospitals in the United Kingdom and were followed for up to 31 weeks.In the study, researchers investigated the incidences of COVID-19 infection by conducting polymerase chain reaction (PCR) tests on the healthcare workers who had tested positive and negative, including both symptomatic and asymptomatic cases.The study results showed that 11,364 did not have antibody levels, and 1,265 had positive results, which also included 88 healthcare workers in whom seroconversion occurred during follow-up. A total of 223 anti-spike–negative health care workers had a positive PCR test (1.09 per 10,000 days at risk), up to 100 during screening were found to be asymptomatic, and 123 were to have symptoms, the study found.Researchers said that individuals who had anti-spike antibodies had no symptomatic infections. 1083

A principal at Education Alternatives in Bedford, Ohio is accused of having a sexual relationship with a student at the school, who was 17 at the time."He says the relationship started when they were upstairs in the gym alone, that she kissed him on the mouth," said Bedford Police Deputy Chief Rick Suts. "Since then, there had been numerous encounters in her van."The teenager told police that his relationship with Courtney Alfred continued for months.Police said the former student came to them last week. Suts said the school knew about the alleged relationship but after their own investigation said the allegations were not credible. Bedford police disagree."He's saying that he took video of them having sex and in that encounter, you see a tattoo. We got a search warrant to see her tattoo, that tattoo matches the one on the video," added Suts.Police said there were also text messages and that money was transferred from Alfred to the teenager. Police said the teen told them it was to keep him from telling her husband.Scripps station WEWS in Cleveland tried to contact Alfred at her home, but there was no answer. WEWS also called the central office for Education Alternatives, but the call was not returned. WEWS also left two messages for her attorney, Vince Ruffa, but Ruffa also did not return messages.Alfred was arrested. She was in court last week facing a sexual battery charge. Alfred is due back in court later this month. 1503

A student was taken into custody Friday after a shooting at a Noblesville, Indiana, middle school left three people injured, officials said.Noblesville police Chief Kevin Jowitt told reporters that a teacher and a student were taken to hospitals with injuries from the shooting at Noblesville West Middle School. But hospital officials said at least three people, including one adult, were being treated. One student had an ankle fracture.Jowitt said the shooting in the city of 60,000, about 25 miles northeast of Indianapolis, was reported shortly after 9 a.m.A student asked for permission to leave the classroom and "he returned armed with two handguns," Jowitt said at an afternoon news conference.The situation was quickly resolved, and the student was arrested in or near the classroom, police public information officer Lt. Bruce Barnes said.Jowitt said a secondary threat was received at Noblesville High School."We have multiple officers and a command post established at Noblesville High School and are diligently ensuring the safety of students and staff there," he said. "We have not received any information that this has been anything other than a communicated threat."Barnes said police are seeking several search warrants in their investigation. Police don't know the motive or where the guns came from, he said.Authorities did not release the name of the suspect or the names and conditions of the injured people. However, the teacher was identified as Jason Seaman, 29, according to his aunt, Brenda Hubly-Sushka.Gov. Eric J. Holcomb, who was returning from a trip to Europe, said in a statement that he was monitoring the situation and that about 100 Indiana State Police officers were made available to work with local authorities."Our thoughts are with all those affected by this horrible situation," his statement said.Vice President Mike Pence tweeted, "Karen and I are praying for the victims of the terrible shooting in Indiana. To everyone in the Noblesville community -- you are on our hearts and in our prayers. Thanks for the swift response by Hoosier law enforcement and first responders."The middle school was on lockdown part of the morning, said Jackie Chatteron, a receptionist for the school district.

A rural Oklahoma school system closed for two days earlier this week after a group of adults made threatening Facebook comments about a 12-year-old transgender girl, Achille Public Schools Superintendent Rick Beene said.The incident began after the student used the middle school girl's bathroom this year at Achille school system in southern Oklahoma, Beene said. In previous years at the district elementary school, she had used the staff bathroom.Two district parents complained about her use of the girl's bathroom in a private Facebook group called "Achille ISD Parents Group," which is not officially affiliated with the school, according to Beene.The threats escalated in severity and number when someone made the Facebook group public, Beene said, and some of the Facebook threats have been traced to other parts of Oklahoma and Texas.According to CNN affiliate KXII, Facebook commenters called the seventh grader, "it" and "thing." One Facebook poster suggested it was open hunting season for transgender people, and others advocated for the 12-year-old to be stabbed or beaten up."That's scary," Brandy Rose, the girl's mother, told KXII. "These are adults making threats to a child. I don't understand it."The Facebook page appears to have since been deleted. Still, Rose said the comments had scared her daughter."She's just an awesome kid. To see any kind of fear in her like that, because other people, especially adults, I can't explain how bad that hurts me," she said. 1498
