Filter by:Long-term aim is the definition of a setup of mobile sensors and their integration in a mobile infrastructure that allows the prediction of stress related alcohol intake in an ambulatory setting. Here, we aim to identify stress- and alcohol cue-related physiological markers in a lab experiment to assess interactions between acute psychological vs. physical stress exposure and alcohol cue-exposure regarding their effects on measures relevant for the development and maintenance of Alcohol Use Disorder (AUD). Further, we aim to identify neural correlates in brain circuits of motivational, cognitive, and affective processing. In addition to applying established stress-related markers, we will integrate innovative sensor-based measures.
The study examines the effects of the combined use of two different non-invasive brain stimulation (NIBS) techniques targeting the DLPFC on stress reactivity and recovery.
The effect of the location of tetanic stimulus on photoplethysmography signals will be studies in patients under general anesthesia.
Stress reactions in emergency physicians will be measures using cortol-awakening-reaction, heart-rate-variability and standardised stress questionnaires
Patients who are involved in a clinical protocol driven 12 week medical weight loss intervention will be randomized to receive either a placebo or 600 mg of an ashwagandha root extract. The study endpoints are primarily the patients self-reported perception of life stress and sleep quality. The working hypothesis of this study is that the addition of aschwagandha to .the medical weight loss program will improve the self-reported perception of life stress and sleep quality
1. PURPOSE OF THE STUDY 1.1 Justification The purpose of the project is to examine the effect of breathing biofeedback and thoughts about stress on performance under stress and cigarette cravings. Smoking rates in the United States have been steadily going down over the past 50 years, and now 16.8% of adults smoke (Centers for Disease Control and Prevention, 2015). Most smokers try to quit, but end up going back to smoking (Garcia-Rodriguez et al., 2013; Piasecki, 2006; Rafful et al., 2013). The reasons people go back to smoking may have something to do with stress in their lives, particularly for women who smoke. This study wants to see if we can reduce temporary stress and lower craving to smoke after stress. 1.2 Description of the Research Project Approximately 60 adult women will participate in the study. Participants must be between 18 and 65 years old, able to read English fluently, and must agree to engage in the research procedures (stress protocol, physiological assessment, breathing training, questionnaires) to participate. People who are taking medications that interfere with physiological assessment are excluded from participating including people with: self-identified substance use problems, self-identified psychosis, morbid obesity (BMI>40), and people who take anti-cholinergic medication, beta blockers, Ritalin, benzodiazepines, tricyclic antidepressants or bupropion, varenicline, antipsychotic medication, or nicotine replacement therapy. People who have a cardiac rhythm abnormality or major neurological problem are also excluded from the study. Also, participants may not participate if they are pregnant or color-blind. Participation is strictly voluntary. 2. PROGRESSION OF THIS STUDY 2.1 Procedures The study visit procedures will take place at the Emotion and Psychopathology Laboratory at Rutgers University, located at the Rutgers Institute for Health, Healthcare Policy, and Aging Research. Participants will first complete some questionnaires and provide some basic information about themselves (demographic information, responses to emotion and stress, and smoking history). Next, participants will engage in a baseline psychophysiological assessment where investigators will examine heart rate, breathing, and blood pressure. Next, investigators will either ask participants to sit quietly for 30 minutes while completing a computer task and watching short videos, or practice a specific deep breathing exercise for 30 minutes. Then participants will do three tasks on a computer. The tasks will ask participants to trace different shapes, answer math problems while receiving feedback about how they're doing, and identify colors and words on a screen. Finally, participants will be asked to sit quietly for 15 minutes before investigators remove the psychophysiological recording equipment. One week after the study visit, investigators will contact participants via phone to ask them some questions about the study visit. 2.2 Duration of the study This study visit will last approximately 3 hours. Length of the visit may vary because each individual may complete procedures at a different pace. The phone call after the study visit will last approximately 10-15 minutes.
The current study will investigate the combination of the two modalities in a mixed-methods design, in order to provide comprehensive knowledge regarding the effects of family-centered MT during KC, on premature-infants' autonomic nervous system stability (measured by parasympathetic tone, physiological vital signs and behavioral states); Parents' anxiety levels; And parents' unique experiences of the intervention. Additionally, the study will analyze separately mothers and fathers to elucidate similar and different effects
In the present study the main goal has been to clarify the effect of the probiotic bacteria Lactobacillus plantarum 299v on the salivary cortisol level in young adults under examination stress. Salivary IgA from minor glands and in whole human saliva was measured as alternative marker of stress. The hypothesis was that the levels of cortisol would be reduced or stabilized in the test group in comparison to the placebo group where the cortisol levels were expected to increase due to the examination-induced stress. By contrast, the salivary IgA levels were expected to increase in the test group in comparison to the placebo group.
