'We are in for a culture change': continuing professional development leaders' perspectives on COVID-19, burn-out and structural inequities.

Introduction: The COVID-19 pandemic positioned healthcare systems in North America at the epicentre of the crisis, placing inordinate stress on clinicians.

Does knowledge have a half-life? An observational study analyzing the use of older citations in medical and scientific publications.

Objectives: In the process of scientific progress, prior evidence is both relied on and supplanted by new discoveries. We use the term 'knowledge half-life' to refer to the phenomenon in which older knowledge is discounted in favour of newer research. By quantifying the knowledge half-life, we sought to determine whether research published in more recent years is preferentially cited over older research in medical and scientific articles.
