David St-Jules

Assistant Professor

Summary

St-Jules’ research broadly investigates the distribution and determinants of dietary intakes of individuals with adiposity-based chronic diseases, and the role of nutrition in the pathogenesis and progression of these conditions. He currently studies dietary recommendations for managing potassium and phosphorus homeostasis, and preventing protein-energy wasting in patients with chronic kidney disease, particularly those on hemodialysis.

Determinants and the role of self-efficacy in a sodium-reduction trial in hemodialysis patients.

2019

2019

J Ren Nutr.

St-Jules DE, Marinaro M, Goldfarb DS, Byham-Gray LD, Wilund KR.

People with chronic kidney disease (CKD) are at increased risk of hyperkalemia, an electrolyte abnormality that can cause serious, sometimes fatal, cardiac arrhythmias. Muscle contraction causes...

2018

Contemp Clin Trials.

Sevick MA, Woolf K, Mattoo A, Katz SD, Li H, St-Jules DE, et al.

Patients with complex chronic diseases usually must make multiple lifestyle changes to limit and manage their conditions. Numerous studies have shown that education alone is insufficient for engaging...

Mirza M, Shahsavarian N, St-Jules DE, Rhee CM, Pompeii ML, Kalantar-Zadeh K, Sevick MA.

Previous literature has shown that hemodialysis patients have impaired dietary intakes on dialysis days (DDs), which may contribute to malnutrition and poor outcomes. In this study, we...

Nutrient non-equivalence: Does restricting high-potassium plant foods help to prevent hyperkalemia in hemodialysis patients?

2016

J Ren Nutr.

St-Jules DE, Goldfarb DS, Sevick MA.

Hemodialysis patients are often advised to limit their intake of high-potassium foods to help manage hyperkalemia. However, the benefits of this practice are entirely theoretical and not supported by...
