Filter by:The proposed study aims to evaluate whether integrating mindfulness practice into an undergraduate biology course influences student levels of mindfulness, stress, positive academic emotions, and physical, mental, and social health outcomes. These outcomes will be evaluated for students who enroll in the biology course compared to students who attempted to register but were put on a waitlist (waitlisted).
The goal of this clinical trial is to evaluate stress and cardiovascular risk factors in women with preeclampsia in the medical history. The main questions it aims to answer are: - to improve our understanding of the underlying psychological and physical stress factors in relation to the circulatory risk profile in women with a history of preeclampsia - to examine the effects of mindfullness based stress reduction (MBSR) or aerobic exercise training on hair cortisol and symptoms of mental stress. Participants will undergo pre- and post-intervention pre-conceptional standard cardiovascular assessments, head tilt test and give a hair sample. As intervention they will sport or do mindfulness for 3 months.They will be compared with a control group.
The goal of this observational study is to define a personalized risk model in the super healthy and homogeneous population of Italian Air Force high-performance pilots. This peculiar cohort conducts dynamic activities in an extreme environment, compared to a population of military people not involved in flight activity. The study integrates the analyses of biological samples (urine, blood, and saliva), clinical records, and occupational data collected at different time points and analyzed by omic-based approaches supported by Artificial Intelligence. Data resulting from the study will clarify many etiopathological mechanisms of diseases, allowing the creation of a model of analyses that can be extended to the civilian population and patient cohorts for the potentiation of precision and preventive medicine.
It is well-accepted that an exaggerated blood pressure (BP) response to physical stress has a prognostic value, indicating a higher cardiovascular risk (e.g., sudden cardiac death, myocardial infarction, future hypertension, and left ventricular hypertrophy). However, there is a limited understanding of the underlying mechanisms and therapuetic strategies modulating this response. Therefore, this pilot project aims to explore whether one session of low-volume high-intensity interval training (low-volume HIIT) or combined intermittent heat and cold bath (sauna+cold bath) can decrease BP responses to physical stress. Furthermore, the secondary goal is to investigate whether one brief session learning about positive stress expectations magnifies the decrease in BP following low-volume HIIT and sauna+ cold bath.
The goal of this clinical trial is to evaluate stress biomarkers, subjective stress levels, and cognitive function in medical students. The main question[s] it aims to answer are: Does regular osteopathic manipulative treatment affect stress in medical students? Does regular osteopathic manipulative treatment affect cognitive function in medical students? Participants will be split into two groups, control and treatment, and undergo a designated protocol for six weeks. The treatment protocol will include weekly sessions of three OMT techniques: paraspinal inhibition, rib raising, and condylar decompression. Concurrently, participants' salivary cortisol levels will be collected weekly and analyzed using an Invitrogen ELISA Immunoassay Kit. Additionally, cognitive function will be assessed weekly via Lumosity, while stress levels are gauged using the College Student Stress Scale (CSSS) survey. Researchers will compare one cohort of medical students who receive weekly OMT and another cohort of medical students who have weekly check-ins without OMT to see if OMT can affect changes in stress biomarkers, subjective stress scales, and cognitive function.
The proposed study uses an experimental design to establish causal support for the role of internalized stress, pertaining to uncertainty with regard to one's sexual orientation, in contributing to heavy drinking behavior. Following exposure to internalized sexual stigma, physiological and psychological stress responses are expected to increase alcohol consumption in adults who are uncertain about their sexual orientation, especially among females, and following consumption, the physiological effects of ethanol and beliefs about the effects of alcohol are expected to alter relations between exposure to sexual stigma and the alleviation of psychological distress. Showing that physiological stress responses, whether driven by the pharmacological effects of ethanol or expectancies regarding its effects, can account for known alcohol-use disparities, particularly in bisexual/bi+ communities, would contribute a great deal to knowledge on the biology of addiction and inform subsequent interventions that seek to regulate stress reactivity.
The Mannheim Multicomponent Stress Test (MMST) is a validated laboratory stress test that combines cognitive, emotional, acoustic and motivational stress components. However the utility of the MMST as a viable alternative to the more commonly used Trier social stress test (TSST) to elicit HPA reactivity remains unclear as meaningful increases in saliva cortisol (> 2.5 nmol/l) have been shown to occur in <50% of participants yet the TSST typically elicits meaningful increases in saliva cortisol in >70% of participants; likely as a consequence of the greater social evaluative component in the TSST. Using a randomised between groups design, this study aims to compare psychobiological responses to the MMST and TSST.
Goal 1: The investigators will quantify lifetime stress burden and examine mechanisms linking Adverse Childhood Experiences (ACEs) and health. The investigators will quantify the early life and total lifetime stress burden of a representative sample of about 725 adults (aged 18+) across northern and southern California. In addition, the investigators will examine how prior life stress exposure and current stress levels are associated with differences in psychosocial, immune, metabolic, physiologic, and clinical outcomes for all participants at baseline. Goal 2: The investigators will develop and test a biopsychosocial intervention using existing programs, platforms, resources, and core components from trauma and resilience research that will target five stress-related domains (i.e., cognitive response style, social relationships, eating, sleep, and physical activity) using cognitive restructuring and mindfulness, interpersonal skills training, mindful eating training, sleep training, and behavioral activation/mobility training. The investigators will then assess the efficacy and acceptability of the intervention in about 425 high stress exposure participants from Goal 1. Following their baseline assessment, about 425 participants will be randomly assigned to receive for 12 weeks (a) personalized intervention, (b) environmental education (active control) or (c) nothing (non-active control). The investigators will also assess the efficacy of the personalized intervention by comparing changes in outcomes by condition from baseline (prior to randomization) to immediately after the intervention, and then again after 12 weeks following intervention completion. The interventions will be entirely online/remote.
This clinical study will be conducted to determine the effects of musically accompanied progressive muscle relaxation and deep breathing exercises on nursing students' stress levels and bio-psycho-social responses to stress. Do musical progressive muscle relaxation and deep breathing exercises have an impact on nursing students' stress levels and bio-psycho-social responses to stress? After students fill in the scales, they will be randomly assigned to the experimental and control groups. The experimental group will be given progressive muscle relaxation and deep breathing exercises accompanied by music once a week for six weeks by the researcher. There will be no intervention in the control group. The scales will be reapplied to the experimental and control groups in the week after the application is completed and two weeks after the application is completed. Groups will be compared and statistical analyzes will be made.
The sociocultural pressure towards women's body image is one of the problems that today afflicts much of the female population. It is a reality that society exerts a strong pressure on body image, particularly on women. The main objective of this study is to analyze the self-perception and self-esteem of people who apply a facial cosmetic. A convenience sample of 150 participants is estimated, who can be randomly included in one of the three groups with different interventions.
