Exposure

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.

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)?

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

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.

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.
