Molecular and Clinical Response to a Single Bout of Aerobic Exercise in a Multimorbid Population: a Study From the Consortium on Precision EXercise in Aging (CPExA)
Integration of Multi-omics, Health Profile, Patient-related Outcomes and Exercise Data to Improve and Personalize Health Care in Hospital Settings: A CPExA Proof of Concept
The combination of data from different origins (biological, health, patient-related) has the potential to improve care for the elderly. Precision approaches that are emerging in health are based on the premise that a better understanding of the biological responses to interventions will make it possible to optimize the treatments. In the field of exercise, this type of approach is emerging. This pilot study aims to collect preliminary data to demonstrate that a patient-centric vision with data from multiple sources is mandatory to personalize exercise intervention and improve health care. Older adults with end-stage chronic disease treated by hemodialysis represent a population of choice that requires personalized care since they are multimorbid and exhibit a complex health profile.
On the other hand, the beneficial effects of exercise are still little understood and the avoidance of adverse effects in response to exercise such as hypotension during dialysis remains uninvestigated.Objective: Demonstrate the feasibility of an integrative approach by combining "omics", clinical data, patient-related outcomes (PRO) as well as exercise variables (e.g., intensity, duration) Methods: A total of 10 people aged 60 and over will be recruited to randomly perform 2 experimental conditions: hemodialysis alone (CONT) or hemodialysis + aerobic exercise (EX), which will be carried out over 2 visits one week apart. These visits will take place at the scheduled time of the hemodialysis treatment. The variables of interest are: blood pressure response to a single bout of exercise exercise (during and post-exercise), symptoms (with visual analogue scales within 36 hours of the visit + Dialysis symptom index for the 7 days after the experimental visit), dialysis efficiency (Kt/V) and biological response (proteomics and metabolomics). Health-related quality of life (KDQOL questionnaire), medical data (electronic medical record), and level of physical activity (PASE questionnaire and smart watch; Apple Watch) will be evaluated.
