Mysterious brain disease killing bald eagles traced to unknown cyanobacterium

Mysterious brain disease killing bald eagles traced to unknown cyanobacterium

Science
March 25 (UPI) -- North America's bald eagles, once severely threatened by DDT exposure, have rebounded dramatically over the last 50 years. In pockets of the American South, however, scientists have found local eagle populations suffering from outbreaks of a mysterious neurodegenerative disease, called avian vacuolar myelinopathy Advertisement Now, nearly 30 years after an outbreak of AVM killed hundreds of eagles in Arkansas, scientists have traced the origins of the deadly disease to a previously unknown cyanobacterium that grows exclusively on an invasive aquatic plant. The revelation -- detailed Thursday in the journal Science -- was made possible by a series of vital breakthroughs, and a fruitful collaboration between scientists in Georgia and Germany. Several years ago, a group of...

Study finds high rates of heart disease among Hispanic men, women

Health
March 4 (UPI) -- More than half of Hispanic men, and nearly half of Hispanic women, in the United States have heart disease, according to an analysis published Thursday by the journal Stroke. Around 60% of Hispanic people also have high blood pressure or high cholesterol, two health problems that place them at high risk for heart disease, the researchers said. Advertisement "It's a wake-up call for the medical community [because] despite our best efforts, Hispanic and Latino populations still seem to be undertreated for their vascular risk factors," co-author Dr. Fernando D. Testai said in a press release. "I didn't expect the numbers to be so dismal," said Testai, an associate professor of neurology at the University of Illinois at Chicago. Researchers reviewed data from the Hispanic Co...

CDC: Israel’s COVID-19 vaccine program lowers cases of severe disease among older adults

Health
Feb. 26 (UPI) -- Widespread acceptance of the COVID-19 vaccine among older adults in Israel has led to a decline in those requiring mechanical ventilation during treatment for the disease, according to data released Friday by the U.S. Centers for Disease Control and Prevention. Israel launched a robust vaccination program in December and, by Feb. 9, 84% of those age 70 and older had received both doses of the Pfizer-BioNTech shot, the agency said. Advertisement From October through December of last year, prior to the start of the vaccination campaign, adults age 70 and older were nearly six times as likely to require mechanical ventilation to treat COVID-19 compared to adults under age 50 years. By February, after widespread vaccination, older adults were just under twice as likely to req...

The second dose of Covid vaccine is needed for complete immunity, infectious disease specialist Dr. Paul Offit says

Finance
The second dose of Covid-19 vaccine is crucial in creating longer and complete immunity as well as preventing variants of the virus, according to Dr. Paul Offit, director of the Vaccine Education Center at Children's Hospital of Philadelphia."We need to know that this is a two-dose vaccine, period," Offit told CNBC's "The News with Shepard Smith." "The second dose of either the Pfizer or Modern vaccine dramatically increases it and induces the kind of cells that suggest you'll have longer term memory, meaning the vaccine would last for a few years. I think if we have people who just get one dose of the vaccine, which will give you shorter and less complete immunity, that's only going to create variants."His comments came afte...
