A study conducted by Stanford researchers found nearly 10% of those tested exhibited coronavirus antibodies. The study was published in the Lancet earlier this week.The study involved dialysis patients and randomly tested over 28,000 samples. The samples were taken in July as part of the patients’ treatment.The data found stark differences based on region. The northeast around 27% of patients with coronavirus antibodies, compared to 3.5% in the west.The study’s authors stressed that the study oversampled minorities. Minorities, the study found, were considerably more likely to have coronavirus antibodies than the rest of the population.“Uncertainty exists as to whether seroprevalence estimates in the dialysis population can be extrapolated to the US population more broadly,” the study reads.The study indicated that herd immunity is still far off, as estimates say at a minimum, 50% of the US population would need to be infected to reach that level. 969

A police union representing officers with the Rochester Police Department claimed Friday that the video of Daniel Prude's arrest that was released by the department was "not complete" and "not accurate."Michael D. Mazzeo, the president of the Rochester Police Locust Club, did not get into specifics as to what was missing from the version of the video released by the Rochester Police Department on Wednesday, citing that an investigation was ongoing.Mazzeo also said that the officers' use of a "spit hood" was within department protocols and consistent with their training, adding that officers had gone through mandated state training between 30 and 40 days prior to the incident.He he added that Prude had made references to have tested positive for coronavirus during the incident.He also called for the New York Attorney General to conduct an "impartial" and "transparent" investigation.Rochester Mayor Lovely Warren suspended seven officers Thursday after video was released that showed officers shoving Prude's head into the ground for about two minutes after finding him naked and bleeding in the street. Prude died a week later after he was taken off life support.Prude's family said he was in the midst of a mental health crisis at the time of the incident.Mazzeo also claimed that one of the suspended officers was not even involved in the Prude incident and called for the city's "law department" to be held accountable for what he described as mistakes in their investigation.He said the Locust Club was not involved in the internal investigation into the incident until Wednesday and was not aware ahead of time that the seven officers would be suspended. Mazzeo added that the union knows "no more than anyone else" about the department's internal investigation. 1787

A Philadelphia woman is hailing a Cleveland Clinic doctor a hero after he helped save her life while on an airplane. On Saturday, 28-year-old Ashley Spencer boarded an American Airlines flight in Philadelphia destined for Cleveland. But shortly after the plane took off Spencer passed out."I stopped breathing," she said. "I still had a pulse. That's when the stewardess said, 'Is there any medical professionals on the aircraft? It's an emergency.'" Spencer, who has a severe peanut allergy, was having an allergic reaction to a bag of chips she had eaten right before the flight. Her body was going into anaphylactic shock. That's when Dr. Erich Kiehl, an electrophysiology fellow from the Cleveland Clinic, and another doctor from North Carolina sprang into action. The men injected Spencer with an Epi-Pen four separate times and monitored her vitals over and over.To make matters even scarier, Spencer suffers from Eosinophilic granulomatosis with polyangiitis (EGPA), a rare auto immune disease. Because of the disease, she said her heart isn't in the best shape. She's spent the last several years in and out of the hospital undergoing several rounds of chemotherapy."When a person is going into anaphylactic shock it has to be taken seriously," she said. "Having Dr. Kiehl on board was so important. He was monitoring the heart completely." The plane made an emergency landing in Pittsburgh and Spencer was rushed to the hospital. She spent Saturday night in the ICU recovering from the reaction. Spencer said she's gone into anaphylactic shock in the past and has received treatment at the hospital, but the help she received from the men in the air was above and beyond."I would have to say the treatment I got on an aircraft was probably better," Spencer said.What's ironic is that Spencer was on the plane to Cleveland because on Monday she's scheduled to meet with doctors at the Cleveland Clinic in her search for answers about her rare disease.Spencer said she is eternally grateful for both doctors who helped her on the plane. She's already purchased plaques for both men as a way to say thank you."I am beyond thankful," she said. "I could have died up there." Spencer said she hopes the Cleveland Clinic can help her meet up with Dr. Kiehl while she's in town.  2428

A pair of former US intelligence chiefs blasted President Donald Trump Sunday after he attacked them a day earlier while discussing his recent conversation with Russian President Vladimir Putin.Former Director of National Intelligence James Clapper said Sunday on CNN"s "State of the Union" that Trump's downplaying of the threat posed by Russia's meddling in last year's election was dangerous to US national security and allows countries like Russia and China to "play" the President. Former CIA Director John Brennan said Trump is allowing Putin to get away with Russia's efforts to disrupt the presidential election.Speaking alongside Brennan, Clapper said: "The threat posed by Russia, as John just said, is manifest and obvious. To try to paint it in any other way is, I think, astounding, and in fact, poses a peril to this country." 848

A surge in COVID-19 cases is further straining the already-depleted supply of prescription drugs in the U.S., according to researchers and doctors at the University of Minnesota."The supply lines are really stressed and stretched," said Dr. Stephen Schondelmeyer, a co-principal investigator for the Resilient Drug Supply Project at the University of Minnesota.Schondelmeyer's work focuses on critical drugs and their supply chains. He tracks the supply chain process for every drug on the marketplace — more than 100,000 in total.Most of the prescription drugs used by Americans are made outside of the country — meaning the U.S. is reliant on foreign companies to manufacture the drug and shipping companies to deliver them safely."We're identifying where it comes from — the first thing you need to know is about 70% of all the drugs that come into the U.S. marketplace are made outside of the US.," Schondelmeyer said.He and his team want to predict and identify when and where there will be failures in the system. Right now, the U.S. has a "fail and fix" system — and right now, there are some critical breakdowns in the supply chain."Seventy-five percent of the COVID-19 drugs are currently in shortage," Schondelmeyer said. "That means three-fourths of the drugs we're using for COVID-19 were already in shortage, and that's before we had this last surge we're seeing.""We should, as a matter of national policy, have a map like we're building of the global drug supply from the beginning all the way until the drug reaches the patient," Schondelmeyer said.But it's not just COVID-19 drugs that are in short supply. Dr. Beth Thielen, an assistant professor of pediatrics at the University of Minnesota Medical School and an infectious disease physician, says even some routine drugs are hard to come by."As a physician working in the hospital — the University of Minnesota — we're a big urban center and yet we're regularly dealing with this issue of shortages in routine things like antibiotics," Thielen said. "It's very concerning to think about the supply chain breaking down and seeing drugs not available in pharmacies or the hospital."Doctors say COVID-19 has unmasked a problem that's been a concern for decades. The pharmaceutical supply chain is complicated and dependent on other countries — and there are supply and demand dilemmas."Start the conversation now with your healthcare provider," Thielen said. "There might be some within class substitutions of medicines, so a drug that is related may not be the exact same drug but might fulfill the same purpose."Schondelmeyer adds that anyone with a regular prescription should ask their doctor about getting a 90-day supply of essential drugs — but adds that there's no reason to hoard medication."We shouldn't panic. We shouldn't treat drugs like we did toilet paper and stock up on so much that we're totally out — and that's an example of what can happen when there's rumors of shortages," Schondelmeyer said. "People act out of fear, and they hoard more than they really need."In the meantime, Schondelmeyer is pushing for a national stockpile of critical medications, so that the U.S. is covered should there be a complete breakdown in the supply chain. 3236
