A Lake Geneva, Wisconsin teenage who was stuck in Paris for weeks after falling into a coma has returned to the United States, his family says.Nathan Dyer returned to the US late Wednesday morning. His family is still raising money to pay off  thousands in medical bills.About a month ago, Dyer embarked on his first journey overseas to Morocco with his cousin. Dyer got sick a week into the vacation and fell into a coma. He was air-lifted to Paris for better care."There were times where I felt completely helpless and had no idea what to do," Dyer's sister said.  As days pass, Dyer said her brother still doesn’t have a diagnosis. 657

A longtime national security aide to President-elect Joe Biden, Antony Blinken, is the leading contender to become Biden's nominee for secretary of state. Multiple people familiar with the Biden team’s planning tell The Associated Press that Blinken is at the front of his choices to be America's top diplomat. Blinken served as deputy secretary of state and deputy national security adviser during the Obama administration. If chosen and confirmed, he would be a leading force in Biden's bid to reframe the U.S. global relationship after four years in which President Donald Trump questioned longtime alliances.The President-elect is moving quickly to fill out his administration and could name other top Cabinet nominations as early as next week. Biden’s team is considering releasing his Cabinet picks in groups focused on a specific topic area. Such a move is intended to deliver the message that Biden is intent on preparing for the presidency even as President Donald Trump refuses to concede and attempts to subvert the election results. 1052

A John Wayne exhibit in the main hall of USC’s School of Cinematic Arts will be removed. The decision comes after renewed visibility of some of the actor’s comments, and recent conversations about removing statues and memorials of those who promoted hateful views."Conversations about systemic racism in our cultural institutions along with the recent global, civil uprising by the Black Lives Matter Movement require that we consider the role our School can play as a change maker in promoting antiracist cultural values and experiences," Assistant Dean of Diversity and Inclusion Evan Hughes said in a statement.While the statement from the University of Southern California did not directly mention it, Wayne’s legacy has been re-examined recently after a 1971 interview with Playboy went viral last year. In the interview, Wayne shared derogatory views of African Americans, Native Americans and films with gay characters."I believe in white supremacy until the blacks are educated to a point of responsibility," the actor said during the 1971 interview. "I don't believe in giving authority and positions of leadership and judgment to irresponsible people."When the interview was widely shared last year, many USC students and others called for the school to remove the Wayne exhibit, according to USC student news outlet Annenberg Media. 1351

A genetic analysis of COVID-19 patients suggests that blood type might influence whether someone develops severe disease.Scientists who compared the genes of thousands of patients in Europe found that those who had Type A blood were more likely to have severe disease while those with Type O were less likely.Wednesday’s report in the New England Journal of Medicine does not prove a blood type connection, but it does confirm a previous report from China of such a link.“Most of us discounted it because it was a very crude study,” Dr. Parameswar Hari, a blood specialist at the Medical College of Wisconsin, said of the report from China. With the new work, “now I believe it,” he said. “It could be very important.”Other scientists urged caution.The evidence of a role for blood type is “tentative ... it isn’t enough of a signal to be sure,” said Dr. Eric Topol, head of the Scripps Research Translational Institute in San Diego.The study, involving scientists in Italy, Spain, Denmark, Germany and other countries, compared about 2,000 patients with severe COVID-19 to several thousand other people who were healthy or who had only mild or no symptoms. Researchers tied variations in six genes to the likelihood of severe disease, including some that could have a role in how vulnerable people are to the virus. They also tied blood groups to possible risk.Most genetic studies like this are much larger, so it would be important to see if other scientists can look at other groups of patients to see if they find the same links, Topol said.Many researchers have been hunting for clues as to why some people infected with the coronavirus get very ill and others, less so. Being older or male seems to increase risk, and scientists have been looking at genes as another possible “host factor” that influences disease severity.There are four main blood types — A, B, AB and O — and “it’s determined by proteins on the surface of your red blood cells,” said Dr. Mary Horowitz, scientific chief at the Center for International Blood and Marrow Transplant Research.People with Type O are better able to recognize certain proteins as foreign, and that may extend to proteins on virus surfaces, Hari explained.During the SARS outbreak, which was caused by a genetic cousin of the coronavirus causing the current pandemic, “it was noted that people with O blood type were less likely to get severe disease,” he said.Blood type also has been tied to susceptibility to some other infectious diseases, including cholera, recurrent urinary tract infections from E. coli, and a bug called H. pylori that can cause ulcers and stomach cancer, said Dr. David Valle, director of the Institute of Genetic Medicine at Johns Hopkins University.Bottom line: “It’s a provocative study. It’s in my view well worth publishing and getting out there,” but it needs verification in more patients, Valle said.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.
