Assessing the performance of a robust multiparametric wearable patch integrating silicon-based sensors for real-time continuous monitoring of sweat biomarkers.

The development of wearable devices for sweat analysis has experienced significant growth in the last two decades, being the main focus the monitoring of athletes health during workouts. One of the main challenges of these approaches has been to attain the continuous monitoring of sweat for time periods over 1 h. This is the main challenge addressed in this work by designing an analytical platform that combines the high performance of potentiometric sensors and a fluidic structure made of a plastic fabric into a multiplexed wearable device. The platform comprises Ion-Sensitive Field-Effect Transistors (ISFETs) manufactured on silicon, a tailor-made solid-state reference electrode, and a temperature sensor integrated into a patch-like polymeric substrate, together with the component that easily collects and drives samples under continuous capillary flow to the sensor areas. ISFET sensors for measuring pH, sodium, and potassium ions were fully characterized in artificial sweat solutions, providing reproducible and stable responses. Then, the real-time and continuous monitoring of the biomarkers in sweat with the wearable platform was assessed by comparing the ISFETs responses recorded during an 85-min continuous exercise session with the concentration values measured using commercial Ion-Selective Electrodes (ISEs) in samples collected at certain times during the session. The developed sensing platform enables the continuous monitoring of biomarkers and facilitates the study of the effects of various real working conditions, such as cycling power and skin temperature, on the target biomarker concentration levels.

A sedentary lifestyle is a significant cardiovascular risk factor and increases premature mortality. Engaging in routine physical activity (PA) provides a wide range of health benefits. Accordingly, physical inactivity must be identified and sedentary patients supported systematically to achieve recommended levels of PA. The level of PA can be assessed by taking patients' history and using specific tools. Support begins by assessing PA contraindications and patients' level of motivation to change their lifestyle. Patients are then encouraged to adopt a more active lifestyle through tailored advice, and if necessary, referred to specialists with expertise in exercise medicine. This article details the key aspects of accompanying sedentary patients, to help healthcare professionals integrate them into their practice.

La sédentarité est un facteur de risque cardiovasculaire et de mortalité prématurée important et la pratique d'une activité physique (AP) procure un éventail large de bénéfices pour la santé. Elle doit donc être identifiée et adressée de manière systématique en consultation médicale. Le niveau d'AP peut être évalué par l'anamnèse et des outils spécifiques. L'accompagnement débute par une évaluation des contre-indications à la pratique d'une AP et du niveau de motivation des patient-es à changer leur mode de vie. Ceux-ci sont ensuite encouragé-es à adopter un mode de vie plus actif à travers des conseils adaptés, et si nécessaire, adressé-es à d'autres spécialistes. Cet article détaille les aspects clés de l'accompagnement des patient-es sédentaires afin d'aider les professionnel-les de la santé à les intégrer dans leur pratique.
