A process that releases iron in response to stress may contribute to heart failure, and blocking this process could be a way of protecting the heart, suggests a study (“Iron derived from autophagy-mediated ferritin degradation induces cardiomyocyte death and heart failure in mice”) published in
eLife.
People with heart failure often have an iron deficiency, leading some scientists to suspect that problems with iron processing in the body may play a role in this condition. The study explains one way that iron processing may contribute to heart failure and suggests potential treatment approaches to protect the heart. ....

There are many factors that may lead someone infected with the coronavirus to suffer severe and potentially fatal outcomes, but the single most common factor linking COVID-19 and death may be diabetes.
Back in August, the U.S. Centers for Disease Control and Prevention analyzed more than 10,000 COVID-related deaths between February and May. The study found that almost 40% of the people who died had diabetes. A study by Reuters found similar results.
This past November, another study conducted in England homed in on one specific complication of diabetes, called diabetic retinopathy. This is a common eye disease among those with diabetes, caused when high blood sugar damages the tiny blood vessels in the retina. This study found that patients with diabetic retinopathy were five times more likely to need intubation when hospitalized with COVID ....
