Hierarchical clustering generated three distinct clusters of patients and a fourth group of 'unclustered' individuals. No relationship was observed between the observed immune clusters and the clinical disease phenotype. CONCLUSIONS Although a clinically useful outcome was not observed through hierarchical clustering, our study provides a rationale for using an UML approach to stratify patients. The study also highlights the predominance of hypo-inflammatory innate immune responses as a key mechanism in the pathogenesis of IBD.Iatrogenic manganese (Mn) neurotoxicity is a safety concern in neonates receiving parenteral nutrition (PN). Prior studies suggest Mn contamination of PN ingredients represents an unintended source of Mn delivery. In order to determine the relative contribution of unsourced Mn to total Mn exposure in neonatal PN, this study measured Mn concentrations in neonatal PN solutions using inductively coupled plasma mass spectrometry. Solutions prepared using a standard fixed dose neonatal multiple trace element product were compared with test solutions prepared using individual trace element ingredients not including Mn. The standard solutions (n = 6) contained a mean (SD) Mn concentration of 56.63 μg/L (0.94), compared with 6.04 μg/L (0.39) in the test solutions without added Mn (n = 6). This study suggests that neonatal PN contains significant quantities of Mn not intentionally added during PN preparation. Further studies are needed to identify individual ingredient sources of unintentional Mn, and the feasibility of Mn omission strategies.Entrustable professional activities (EPAs) are critical activities performed by medical professionals which can be observed and assessed.
