Using Trace Element Data

Hugh Rollinson, Victoria Pease · Cambridge University Press eBooks · 2021

The behaviour of trace elements in geochemistry may be understood in terms of the chemical properties of their ions and the way in which they are partitioned between solid (mineral) and melt phases during the melting and solidification of igneous rocks and their sources. However, partition coefficients vary according to a large number of physical parameters such as temperature, pressure, melt composition and oxygen fugacity, and these effects can be modelled using the results of experimental petrology and thermodynamic analysis. Trace element data for both igneous and sedimentary rocks are plotted according to their geochemical properties and may be displayed on bivariate diagrams, rare earth element (REE) plots, multi-element plots normalised to the composition of the Earth’s primitive mantle or as highly siderophile elements (HSE). The physical understanding of trace element distributions means that they can be modelled during partial melting, fractional crystallisation and assimilation and comparisons made with the measured compositions of natural rock samples.

Example data element hierarchy.

Craig S. Mayer (9461067), Vojtech Huser (432058) · Figshare · 2023

&lt;div&gt;&lt;p&gt;There are many initiatives attempting to harmonize data collection across human clinical studies using common data elements (CDEs). The increased use of CDEs in large prior studies can guide researchers planning new studies. For that purpose, we analyzed the All of Us (AoU) program, an ongoing US study intending to enroll one million participants and serve as a platform for numerous observational analyses. AoU adopted the OMOP Common Data Model to standardize both research (Case Report Form [CRF]) and real-world (imported from Electronic Health Records [EHRs]) data. AoU standardized specific data elements and values by including CDEs from terminologies such as LOINC and SNOMED CT. For this study, we defined all elements from established terminologies as CDEs and all custom concepts created in the Participant Provided Information (PPI) terminology as unique data elements (UDEs). We found 1 033 research elements, 4 592 element-value combinations and 932 distinct values. Most elements were UDEs (869, 84.1%), while most CDEs were from LOINC (103 elements, 10.0%) or SNOMED CT (60, 5.8%). Of the LOINC CDEs, 87 (53.1% of 164 CDEs) originated from previous data collection initiatives, such as PhenX (17 CDEs) and PROMIS (15 CDEs). On a CRF level, The Basics (12 of 21 elements, 57.1%) and Lifestyle (10 of 14, 71.4%) were the only CRFs with multiple CDEs. On a value level, 61.7% of distinct values are from an established terminology. AoU demonstrates the use of the OMOP model for integrating research and routine healthcare data (64 elements in both contexts), which allows for monitoring lifestyle and health changes outside the research setting. The increased inclusion of CDEs in large studies (like AoU) is important in facilitating the use of existing tools and improving the ease of understanding and analyzing the data collected, which is more challenging when using study specific formats.&lt;/p&gt;&lt;/div&gt;
