Arizona Sen. John McCain, a former Republican presidential nominee and prisoner of war, has died after a battle with an aggressive form of brain cancer.The 30-year Arizona Senator leaves behind wife, Cindy, and 7 children.John Sidney McCain III, 81, was the son and grandson of Navy admirals. He was born August 29, 1936.As a naval pilot, he narrowly escaped death in a fire aboard the USS Forrestal in 1967. Also in 1967, McCain's plane was shot down over Hanoi, and he was captured by North Vietnamese troops. He was tortured during more than five years as a prisoner of war.RELATED:?50 photos that capture John McCain's personalityCelebrity deaths of 2018: Remembering those we've lost this yearAfter retiring from the Navy in 1981, he moved in Arizona and ran for Congress, winning a U.S. House seat the following year.After two terms, he was elected to the U.S. Senate, succeeding Barry Goldwater, and served in the role until his death.McCain married Cindy Hensley, his second wife, in 1980. She is the daughter of an Arizona beer distributor.McCain is father to seven children, including Bridget, a daughter adopted from Bangladesh. Another daughter, Meghan McCain, is a television host on ABC’s The View.A low point in his political career came when McCain was implicated in the Keating Five campaign contribution scandal of the 1980s. The senator emerged with a new passion to reform money in politics. Called a maverick, he bucked his party as he worked with Democrats on campaign finance and other issues.McCain also campaigned for president in 2000 and 2008. In 2008, he won the Republican nomination with a surprising choice of running mate, then-Alaska Gov. Sarah Palin.After his second failed presidential bid, McCain continued as senator, assuming the role of an elder statesman. He visited troops overseas and dug into foreign policy. McCain, due to the lasting impacts of his torture as a POW, could not lift his arms above his head. He had other health scares, including bouts of skin cancer that left a large scar on his cheek. In July 2017, Sen. McCain was diagnosed with glioblastoma, the deadly brain cancer which took his life.Even in his waning days, McCain lived up to his reputation as a maverick. In August 2017, less than two weeks after surgery to remove his tumor, McCain returned to the U.S. Senate floor to become the deciding "no" vote on repealing Obamacare.Senator McCain had a joke he famously told throughout his life. Whenever he got upsetting news, he said he slept like a baby, explaining that he slept two hours, woke up and cried, then slept two more hours and did the same. It’s that wit that many of his closest friends say they’ll remember him by in the days ahead.No funeral arrangements have been announced, but in an interview with “60 Minutes”, Senator McCain recently said he wanted the ceremony to take place at the Naval Academy in Maryland.  2913

As governors around the country consider new or stricter restrictions to control the latest surge in coronavirus cases, a recently published study identifies restaurants, cafes and gyms as some of the places having the highest risk of coronavirus spread outside the home.The study, published this week in the journal Nature, looked at data from millions of Americans, tracked by their phones as they went about daily life during the first wave of the pandemic this spring.They used the data and an epidemiological model to run simulations on viral spread at points of interest outside the home. Their findings in the simulations closely matched actual coronavirus caseloads, according to the Washington Post.“We found large variation in predicted reopening risks: on average across metro areas, full-service restaurants, gyms, hotels, cafes, religious organizations, and limited-service restaurants produced the largest predicted increases in infections when reopened,” the study states.Researchers say these locations pose more risk because the mobility data, data showing how mobile people are at these places, shows Americans tend to spend longer amounts of time and at a higher density of people.Their models add support to pandemic measures around the country that limit capacity at some of these points of interest, including capping indoor gatherings to a certain percentage or number of people.“Reducing maximum occupancy substantially reduced risk without sharply reducing overall mobility: capping at 20% maximum occupancy in the Chicago metro area cut down predicted new infections by more than 80% but only lost 42% of overall visits, and we observed similar trends across other metro areas,” researchers stated.The study also looked at disparities in lower income neighborhoods, where more of the population has to leave their home for essential jobs, grocery delivery may not be available or is financially not possible, and businesses tend to be smaller and potentially more crowded.“Because disadvantaged groups suffer a larger burden of infection, it is critical to not just consider the overall impact of reopening plans but also their disparate impact on disadvantaged groups specifically,” the study states.The researchers hope the information is helpful to policymakers and city leaders as they consider reopening restrictions. 2356

An artificial intelligence tool can help doctors when deciding which COVID-19 patients can be sent home, according to a study that started in May.Researchers at New York University used the AI tool to analyze thousands of COVID-19 cases. The team used data from Asia and Europe to develop the model.It uses lab results, vital signs and oxygen requirements to determine how the patient will do over the next few days.The study has found the AI tool can identify patients that will do well with 90% precision, which could help doctors prioritize care and make discharging plans for others.Doctors always make the final call, but the AI tool can help reaffirm their decisions.“It's augmenting, but it's also teaching a little bit, because you know when the physicians see a patient that looks well, but the models say they may not be well, they can look at the, the features right? The vital signs and labs and other things that are saying that this patient isn't well and then they can start to understand or create a mental model,” said Yin Aphinyanaphongs, Director of Translational Clinical Informatics for DataCore, NYU.The researchers are still running randomized trials for about another two months, looking at the average time patients spend in the hospital.The hope is the AI tool could help reduce the length of stay.“That's extremely compelling because now you don't just show oh I have a model that can predict a favorable outcome, but now you have a model, right, that actually affects the outcome,” said Aphinyanaphongs.Another team at NYU is now conducting a survey among doctors that have used the tool. One facility has already implemented it.The researchers wanted to make sure it's easy for other organizations to start -- so the software can be up and running in about half a day. 1805
