Vitamin D levels appear to play role in COVID-19 Mortality Rates

covid backman vitamin D

Patients with severe deficiency are twice as likely to experience major complications. Researchers analyzed patient data from 10 countries. The team found a correlation between low vitamin D levels and hyperactive immune systems. Vitamin D strengthens innate immunity and prevents overactive immune responses. The finding could explain several mysteries, including why children are unlikely to die from COVID-19.

After studying global data from the novel coronavirus (COVID-19) pandemic, researchers have discovered a strong correlation between severe vitamin D deficiency and mortality rates.

Led by Northwestern University, the research team conducted a statistical analysis of data from hospitals and clinics across China, France, Germany, Italy, Iran, South Korea, Spain, Switzerland, ...

Bat ‘Super Immunity’ may explain how Bats Carry Coronaviruses, study finds

Bat-virus adaptation may explain species spillover, researchers say. A University of Saskatchewan (USask) research team has uncovered how bats can carry the Middle East respiratory syndrome (MERS) coronavirus without getting sick — research that could shed light on how coronaviruses make the jump to humans and other animals.

Coronaviruses such as MERS, Severe Acute Respiratory Syndrome (SARS), and more recently the COVID19-causing SARS-CoV-2 virus, are thought to have originated in bats. While these viruses can cause serious and often fatal disease in people, for reasons not previously well understood, bats seem unharmed.

“The bats don’t get rid of the v...

More Berries, Apples and Tea may have protective benefits against Alzheimer’s

Study shows low intake of flavonoid-rich foods linked with higher Alzheimer’s risk over 20 years. Older adults who consumed small amounts of flavonoid-rich foods, such as berries, apples and tea, were two to four times more likely to develop Alzheimer’s disease and related dementias over 20 years compared with people whose intake was higher, according to a new study led by scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University.

The epidemiological study of 2,800 people aged 50 and older examined the long-term relationship between eating foods containing flavonoids and risk of Alzheimer’s disease (AD) and Alzheimer’s disease and related dementias (ADRD)...

Antibodies from llamas could help in fight against COVID-19, study suggests

Researchers linked two copies of a special kind of produced by llamas to create a new antibody that binds tightly to the spike protein on the coronavirus that causes COVID-19. This spike protein allows the virus to break into host cells. Initial tests indicate that the antibody blocks viruses that display this spike protein from infecting cells in culture.

The hunt for an effective treatment for COVID-19 has led one team of researchers to find an improbable ally for their work: a llama name...
