Intervention to Reduce Exposure to Environmental COntaminant (IRECO)
Main objective The intervention study IRECO aims to (1) modify habits of personal care product use for the participants and (2) evaluate the impact of those modification on urinary concentration for the following compounds: phthalates, phenols and glycol ether. Secondary objectives: The secondary objectives of this study aim to evaluate: 1. impact of modification of personal care product on the levels of biomarkers linked to exposure to environmental pollutant other than phthalates phenol and glycol ether (untargeted analysis) and biomarkers related to health (such as inflammatory biomarkers and oxidative stress). 2. hazard perception linked to the exposure to chemical product present in personal care product 3. barriers to change habits allowing to decrease exposure to environmental pollutant on short and long term as well as levers allowing to remove those barriers.

French Military Firefighters to Assess Relationships Between Exposome and Health.
The aim of the study is to describe professional exposures and health events among French military firefighters (both active-duty personnel and veterans) and identify potential relationships between the exposome (the total history of occupational and personal exposures) and health status in these populations. The study is based on a self-administered questionnaire that collects retrospective and present information about exposures and health conditions.

How Digital Media Affects Kids' Healthcare Experiences and Outcomes
The goal of this clinical trial is to learn whether different forms of media (2D, 360, or 360 in virtual reality) have different impacts on pre-procedural anxiety and post-procedural pain in children. The main questions it aims to answer are: Does one type (and richness) of media reduce pre-procedural anxiety and post-procedural pain more than another type of media? For example, will learning about an upcoming procedure by watching a 360 video in virtual reality reduce pre-procedural anxiety more than learning about the same upcoming procedure by watching it in a 2D video or 360 video? The second question is whether watching a 360 video in VR about an upcoming procedure more effective in reducing pre-procedural anxiety and post-procedural pain compared to the 2D video or the 360 video without VR groups for specific procedures? For example, is watching an explanation of a procedure in VR always more effective in reducing pre-procedural anxiety and post-procedural pain, or is it procedure specific (i.e., watching a video about surgery preparation is more effective in VR, but for cast removal it doesn't matter whether participants learn about their procedure viewed through VR, 360 video, or 2D)?

Agile Development of a Digital Exposure Treatment for Youth With Chronic Musculoskeletal Pain
This project proposes to systematically develop and evaluate the feasibility and preliminary effectiveness of a digitally delivered, graded exposure treatment for youth with chronic musculoskeletal pain, utilizing a sequential replicated and randomized single-case experimental design (SCED). SCED provides the opportunity to rigorously evaluate treatment effectiveness at the individual level. Development of iGET Living will be based on a series of short iterations, with alpha testing (Aim 1) on a small sample of adolescents with chronic pain (N = 15). For Aim 1, participants will participate in three, two hour focus groups (one per week over the course of three weeks), resulting in 6 total hours of participation per participant for Aim 1. Aim 2 will involve a sample (N = 20 youth) of naïve end-users. Participants will be enrolled in a baseline period ranging from 7-25 days (done to support SCED methodology) after which they will be enrolled in the online intervention program, lasting 6-weeks. Patients will be contacted 3-months post-discharge from treatment (week 22 of enrollment) and will complete self-report outcome measures at this time.

Firefighter Collaborative Research Project
The goal of this research is to test interventions to reduce firefighter cardiovascular, cognitive, and overall disease risks, including but not limited to risks associated with Per- and Polyfluorinated Substances (PFAS) exposure. Approximately 1,500 - 2,000 firefighters will be enrolled in the Fire Fighter Cancer Cohort Study (FFCCS). Among these individuals, those that express interest will then be screened for eligibility for the Firefighter Collaborative Research Project (FCRP) using information they provided for the Fire Fighter Cancer Cohort Study. Firefighters enrolled in the study will provide an initial blood sample and urine sample. The blood sample will be analyzed to determine the participant's PFAS levels. Based upon serum PFAS levels and responses from the screening survey, eligible participants will be randomly assigned into one of the following interventions: 1. Blood Donation, or Plasma Donation or Blood/Plasma Control Group; 2. Zone 2 Training or Zone 2 Control; 3. Intermittent Fasting or Intermittent Fasting Control. Individuals participating in the blood donation, plasma donation or blood/plasma control group would donate blood every 12 weeks, plasma every 6 weeks, or not donate blood or plasma. Participants in this intervention arm would continue this for a 12-month period. Individuals in the zone 2 training, zone 2 training control, intermittent fasting or intermittent fasting control group would participate in their intervention or control for a 4-month period. After 4 to 12 months participating in an intervention or control group, participants will be asked to provide a final urine sample and blood draw to determine if and to what degree their PFAS levels or other cardiovascular disease and other health risks have changed.

Evaluate a Local Program to Reduce the Risky Use of Screens by Children Under 3, Based on the Experience of Parents Who Successfully Stopped This Exposure.
Early exposure to screens puts children at risk of later neurodevelopmental delay. This exposure is particularly prevalent among the underprivileged populations in our study area, and we don't yet know the motivations, factors and constraints that need to be put in place to remedy the situation. Our approach is a bottom-up study, based on the experience of parents who stopped their child's exposure to screens before age 3, to develop a program to reduce early exposure to screens. This will then be tested on a larger scale via a randomized trial

Cohort Study on Plant-based Diets (COPLANT Study)
The Cohort on Plant-based Diets (COPLANT) study is a multi-centre cohort study that starts baseline recruitment from 2024 to 2027 with approximately 6,000 participants in Germany and Austria. The COPLANT study focuses on vegan (no animal products), vegetarian (no meat and fish, but dairy products and eggs), pescetarian (no meat, but fish) and omnivorous (mixed diet including all possible animal products) diets. The aim of the COPLANT study is to gain new insights on health benefits and risks as well as social, ecological and economic effects of different plant-based diets in comparison to a mixed diet. In addition to a detailed dietary survey using an app adapted to the needs of this study, the baseline examination includes measurements of body composition, bone health, cardiovascular risk factors, diabetes risk, contaminants and lifestyle. For the basic laboratory program, fasting blood, 24-hour urine collection and a stool sample are taken from all study participants. Furthermore, specific aspects of dietary behavior, physical activity and other lifestyle factors are collected via questionnaires. Follow-up studies are planned at intervals of 5, 10 and 20 years after the baseline visit.

One Session Virtual Reality During Ongoing Treatment for Anxiety: Feasibility in Children and Adolescents
The goal of this study is to evaluate one session with exposure with Virtual Reality (VR) in in children and adolescents, aged 8-18 years with an anxiety disorder. The main questions it aims to answer are: 1. What are the expectations of children and adolescents and therapists with VR exposure? 2. What is the acceptability of the VR session (positive and negative effects)? 3. What are possible working mechanisms of VR exposure? During ongoing treatment, participants will receive a session of exposure with VR.
