Acta Biomedica (ABM) invites several of scientific and medical experts each year to review submitted manuscripts. The Editors of ABM sincerely appreciate the efforts of these reviewers who volunteer their time and expertise to provide valuable feedback to ensure the quality of the research published in each issue of ABM. Without their efforts ABM could not have maintained its standards during the current coronavirus disease (COVID-19) pandemic, given the rapid pace and unprecedented number of reports submitted in such a short time.

Many thanks for their outstanding contributions and dedication in 2021.
