Overview
Brief Summary
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.

Outcomes
Primary Outcomes
Change in perceived fatigue
Time Frame: Measured at 2:00 pm and 6:00 pm the day of the experimental condition and at 10:00 am, 2:00 pm and 6:00 pm the day following the experimental condition (for a total of 24 hours).
10-centimeter horizontal visual analog scale, going from no fatigue (left) to extreme fatigue (right)
Plasma Metabolome and proteome at the end of the control (rest) condition
Time Frame: After 30 minutes of rest
A blood draw will be realized immediately at the end of the dialysis session representing the control condition. The plasma metabolome and proteome will be determined using mass spectrometry.
Change in mood
Time Frame: Measured at 2:00 pm and 6:00 pm the day of the experimental condition and at 10:00 am, 2:00 pm and 6:00 pm the day following the experimental condition (for a total of 24 hours).
10-centimeter horizontal visual analog scale, going from very bad (left) to very good (right)
Change in perceived soreness
Time Frame: Measured at 2:00 pm and 6:00 pm the day of the experimental condition and at 10:00 am, 2:00 pm and 6:00 pm the day following the experimental condition (for a total of 24 hours).
10-centimeter horizontal visual analog scale, going from no soreness (left) to extreme soreness (right)
Change in perceived sleepiness
Time Frame: Measured at 2:00 pm and 6:00 pm the day of the experimental condition and at 10:00 am, 2:00 pm and 6:00 pm the day following the experimental condition (for a total of 24 hours).
10-centimeter horizontal visual analog scale, going from no sleepiness (left) to extreme sleepiness (right)
Plasma Metabolome and proteome at the end of the experimental (exercise) condition
Time Frame: After 30 minutes of exercise
A blood draw will be realized immediately at the end of the dialysis session comprising the exercise condition. The plasma metabolome and proteome will be determined using mass spectrometry.
Change in blood pressure
Time Frame: Before and after the condition as well as every 5 minutes during the 20 minutes after (10 measurements). After this time frame, each 30 minutes up to the end of the dialysis session.
Measured using standard clinical procedures (Automatic Blood Pressure Monitor at rest and with aneroid sphygmomanometer during and after exercise)
Change in perceived sleep quality
Time Frame: Measured at 10:00 am the day following the experimental condition.
10-centimeter horizontal visual analog scale, going from very bad (left) to extreme soreness (right)
Single pool Kt/V, experimental (exercise) condition
Time Frame: After 4 hours of dialysis
measured using standard clinical procedures (blood draw before and at the end of the dialysis session comprising the exercise condition, by a research nurse).
Single pool Kt/V, control (rest) condition
Time Frame: After 4 hours of dialysis
measured using standard clinical procedures (blood draw before and at the end of the dialysis session representing the condition, by a research nurse).
