Context and Positioning
Homeostasis is the process by which living organisms maintain a stable internal balance necessary for their survival and optimal functioning. This process typically involves feedback mechanisms that detect deviations from a target state and activate responses to correct these deviations and return the system to a stable level. The homeostasis capabilities of an individual are used to support medical decision making, such as patients’ peri-operative risk stratification in lung cancer surgery.The homeostatic abilities of an individual can be assessed through exercise testing, which is the traditional clinical method for evaluating patients’ health status and overall systemic dynamics. A series of tests is designed to measure features representative of the individual’s homeostatic capabilities, with one significant metric being the maximal oxygen uptake (VO2max). These measurements are obtained through routine functional tests and maximal exercise sessions, aimed at challenging the entire organism to evaluate physiological adaptive responses. When exercise performance or maximal aerobic capacity is limited for a given patient, the medical doctor has to identify the failing physiological function and to provide a coherent system failure mechanics analyzing the monitored data. However, medical doctors still analyze the collected physiological data in a univariate approach as historically developed. Currently, in the research community, the human body is considered as a dynamic physiological complex system. Recently, the framework of network physiology was proposed, giving a central role to homeostasis.To broaden theoretical knowledge and to fill the gap between current research and medical practice, the Exercise Test Laboratory of Hôpitaux Universitaires de Marseille built its own activity database composed of 2500 exercise tests.Objectives
This thesis aims at exploiting this dataset in order to provide a global understanding and interpretation framework of the multivariate data generated during maximal exercise testing to improve patients’ homeostasis phenotyping through their homeostatic capabilities.We aim to develop a medically and statistically consistent approach to identifying and quantifying determinants of overall performance as well as aerobic performance from monitored variables. This would provide physicians with improved analytical tools to achieve a more relevant and precise patient exercise phenotyping.The thesis project aims to go further and provide physicians with a quantitative decision support indicator. It will be developed by focusing on the dynamic interactions between the recorded variables. Here, we consider in particular adapting the framework of physiological networks to the mesoscopic and macroscopic case of exercise tests. This would provide crucial information to the physician about patients’ homeostatic capacities.Work environment
