About the Project

Acute kidney injury (AKI) is a common consequence of acute illness impacting >13-million individuals worldwide each year. Despite this high prevalence and growing recognition of a prolonged symptom burden after recovery from AKI, little attention has been given to potential strategies to improve physical function in AKI patients. Reduced physical function is a substantial burden in those recovering from AKI, postulated to be due, at least in part, to losses of skeletal muscle mass and function during hospitalisation for AKI. Emerging evidence suggests that daily neuromuscular electrical stimulation (NMES) of the quadriceps can reduce losses of muscle mass and function in older cancer patients’ recovering from surgery. However, how this strategy may benefit AKI patients is not yet known. This PhD will use physiological assessments, molecular biology methods and novel imaging techniques to determine: i) the impact of in-hospital NMES on muscle mass and function in AKI patients during their hospital stay and ii) 3-months after hospital discharge; and iii) the potential of an emerging blood-based biomarker to assess muscle mass in AKI patients. Overall, this project will provide the successful candidate with varied skills and experience across the translational research pathway (i.e., bench-to-bedside).
