Preprint / Working Paper
Sharpe, H., Allen, K., Goldsmith, K. A., Lawrence, V., Byford, S., Monssen, D., Davies, M. R., Prasad, V., Potterton, R., Mountford, V., McNeil, S., Grant, N., Glennon, D., Brown, A., & Schmidt, U. (2025). A randomised controlled feasibility trial of FREED-Mobile, a smartphone friendly decision tool, designed to facilitate help-seeking in young people with eating disorders

Background: Early intervention increases the likelihood of eating disorder (ED) recovery but many young people delay help-seeking. We developed a smartphone-friendly, online decision-making tool to address this gap (FREED-Mobile [FREED-M])and conduct...

Journal Article
Swiderski, M. A., Figueredo, G., Vinogradova, Y., Knaggs, R. D., Harman, K. E., Harwood, R. H., Prasad, V., Persson, M. S., Layfield, C., & Gran, S. (in press). Determining the most frequent combinations of drugs prescribed prior to bullous pemphigoid diagnosis using association rule mining: a UK population-based case-control study.

Background

Bullous pemphigoid (BP) is a serious autoimmune skin disease affecting older people. Given the highly prevalent polypharmacy in older people, identifying drug combinations associated with high BP risk is needed.

Objectives

To iden... Read More about Determining the most frequent combinations of drugs prescribed prior to bullous pemphigoid diagnosis using association rule mining: a UK population-based case-control study.
