State-dependent Interoception, Value-based Decision-making, and Introspection

Background: Negative emotional states can affect a person s behavior as they make decisions. For example, hunger may make people more impatient; they may then make riskier choices. Other negative emotional states that can change behavior include stress, pain, and sadness. By learning more about how emotions affect thinking and behavior in healthy people, researchers hope to better understand how to identify and treat people with mental disorders. Objective: To learn how negative emotions affect the brain and decision-making behavior. Eligibility: Healthy people aged 18 to 55 years. Design: Participants will have 3 clinic visits in 3 weeks. Participants will fill out questionnaires. They will be asked about their personal history, their personality, and state of mind. For 2 visits, participants will be assigned to different groups. Each group will experience 1 type of emotional stressor: Some participants will watch a video. Some will have to do arithmetic problems. Some will have heat applied to an arm or leg. Some will experience cold by immersing their hand in ice water. For a snack craving test, some will be tempted by food after a 4-hour fast. During these tests, participants will have sensors attached to their bodies. They will be videotaped. Saliva samples will be collected. After the stressors, participants will do tasks on a computer. They will need to make choices. Some participants will perform these decision-making tasks while lying in a brain scanner for functional magnetic resonance imaging. The brain scan involves lying on a table that slides into a cylinder that takes images of the brain. ...

Work-Related Frustration and Higher Cardiovascular Risk Blood Pressure Profiles

Background: Mental health is a national priority in France, especially in the workplace. The impact of poor quality of life at work on mental health has been demonstrated. Raising awareness of the importance of prevention within companies and the influence of working conditions seems essential. In the context of limited occupational health physicians, inherent access difficulties, and reduced resources, physical health is often addressed as the first line of intervention. In the Burgundy region, the prevention of cardiovascular diseases is a regional public health concern. A significant association has been found between effort/reward imbalance and masked hypertension. Identifying a link between working conditions, blood pressure profile, and thus increased cardiovascular risk would be relevant. Objectives: The main goal of this observational study is to compare the frequency of blood pressure profiles at higher risk of cardiovascular events (white coat hypertension and daytime and/or nighttime masked hypertension) according to work-related quality of life and perceived stress levels among primary care patients without a history of hypertension or cardiovascular disease, in two departments of the Burgundy region. Methods: This project is a proof-of-concept study before intervention on work-related quality of life and blood pressure profiles at higher cardiovascular risk in primary prevention. It is a prospective, interventional, and multicenter study, conducted from May 2023, across three multidisciplinary primary care centers, involving fifteen general practitioners from Côte d'Or and Saône-et-Loire. Patients aged 40 to 65, consulting one of the participating general practitioners, actively working, with no cardiovascular history or antihypertensive treatment, will be included. Work-related quality of life and perceived stress will be assessed using the QualTra-Scale and the PSS-10 scale, respectively. All included patients will undergo 24-hour ambulatory blood pressure monitoring (ABPM) during a workday. A qualitative component will complement the results through patients' individual interviews exploring ABPM perception and reasons for refusal, and focus groups involving general practitioners and occupational health professionals to explore perceptions and potential intervention strategies. Perspectives: The main perspective of this study is to focus on workplace health by providing additional data on the physical repercussions of poor work-related quality of life and high perceived stress. Objectifying a confirmed medical situation could serve as a lever for identifying mental health issues. It would enable interventions to improve work-related quality of life by addressing health determinants and psychosocial risks. Various interventions could be considered through a multidisciplinary approach in the workplace, involving occupational physicians, occupational psychologists, and employers. This study could also offer insights into patient profiles at higher cardiovascular risk, help develop recommendations for screening masked hypertension, and evaluate the role of blood pressure measurements at the workplace.
