COVID-19 infection among first responders in Broward County, Florida, March-April 2020.

Background: First responders (FRs) may have a significant risk of coronavirus 19 (COVID-19) infection than the general population due to job-related exposures. We aimed to determine the prevalence and exposure patterns of COVID-19 among FRs.

Trace elements status in diabetes mellitus type 2: possible role of the interaction between molybdenum and copper in the progress of typical complications.

It is well established that both, the deficiency and possible overload of mineral micronutrients have adverse health effects. It is also generally accepted that non-essential xenobiotics contribute to oxidative damage, which is considered one of the principal factors in diabetes and its complications. The purpose of this work was to gain an insight on the global role of metal/metalloids in the progress of diabetes mellitus type 2.
