Improving Cross-Sector Comparisons: Going Beyond the Health-Related QALY

The quality-adjusted life-year (QALY) has become a widely used measure of health outcomes for use in informing decision making in health technology assessment. However, there is growing recognition of outcomes beyond health within the health sector and in related sectors such as social care and public health. This paper presents the advantages and disadvantages of ten possible approaches covering extending the health-related QALY and using well-being and monetary-based methods, in order to address the problem of using multiple outcome measures to inform resource allocation within and between sectors

Functional and informatics analysis enables glycosyltransferase activity prediction

The elucidation and prediction of how changes in a protein result in altered activities and selectivities remain a major challenge in chemistry. Two hurdles have prevented accurate family-wide models: obtaining (i) diverse datasets and (ii) suitable parameter frameworks that encapsulate activities in large sets. Here, we show that a relatively small but broad activity dataset is sufficient to train algorithms for functional prediction over the entire glycosyltransferase superfamily 1 (GT1) of the plant Arabidopsis thaliana. Whereas sequence analysis alone failed for GT1 substrate utilization patterns, our chemical–bioinformatic model, GT-Predict, succeeded by coupling physicochemical features with isozyme-recognition patterns over the family. GT-Predict identified GT1 biocatalysts for novel substrates and enabled functional annotation of uncharacterized GT1s. Finally, analyses of GT-Predict decision pathways revealed structural modulators of substrate recognition, thus providing information on mechanisms. This multifaceted approach to enzyme prediction may guide the streamlined utilization (and design) of biocatalysts and the discovery of other family-wide protein functions
