The Corona Virus Disease 2019 (COVID-19) pandemic represents an ongoing worldwide challenge. The present large study sought to understand independent and overlapping metabolic features of samples from acutely ill patients (n = 831) that tested positive (n = 543) or negative (n = 288) for COVID-19. High-throughput metabolomics analyses were complemented with antigen and enzymatic activity assays on plasma from acutely ill patients collected while in the emergency department, at admission, or during hospitalization. Lipidomics analyses were also performed on COVID-19-positive or -negative subjects with the lowest and highest body mass index (n = 60/group). Significant changes in amino acid and fatty acid/acylcarnitine metabolism emerged as highly relevant markers of disease severity, progression, and prognosis as a function of biological and clinical variables in these patients. Further, machine learning models were trained by entering all metabolomics and clinical data from half of the COVID-19 patient cohort and then tested on the other half, yielding ~78% prediction accuracy. Finally, the extensive amount of information accumulated in this large, prospective, observational study provides a foundation for mechanistic follow-up studies and data sharing opportunities, which will advance our understanding of the characteristics of the plasma metabolism in COVID-19 and other acute critical illnesses.

Medication-related errors are among the most common medical errors, and studies have shown that the paediatric population is particularly vulnerable. Errors can occur during any step in the medication process. This review article seeks to highlight new advancements in the field of paediatric medication safety at each stage of the medication process, from ordering and transcribing to medication dispensing and administration. We will focus on interventions that are increasingly widely used, such as computerised provider order entry with clinical decision support, barcoding technologies and safe medication administration through technologies pumps (SMART pumps), as well as innovative mobile application devices and workflow management systems that are being piloted at single institutions. By highlighting what is new in paediatric medication safety, as well as the gaps that remain, we hope to continue to foster focus on this critically important area in order to create the safest possible environment for children.
