Filter by:Beta blockers (BB) play an important role in protection of end organs that are susceptible for secondary injury by the Traumatic brain injury (TBI)-induced catecholamine surge. However, use of BBs in trauma patients is not yet the standard of care which necessitates clear scientific evidence and justification to be used especially in TBI patients. The BBTBBT study aims to determine whether early administration of propranolol based on the HSTnT status will improve the outcome of mild-to-severe TBI patients. Our primary hypothesis is that BBs are effective in reducing 10 and 30-day mortality in TBI patients.BBs are effective in reducing 10 and 30-day mortality in TBI patients. Methods/Design: The BBTBBT study is a prospective, randomized, double-blinded, placebo-controlled trial, three-arm trial of BB use in mild-to-severe TBI patients based on the HsTnT status.
The Professional Peer Resilience Initiative (PPRI) study is an observational study aimed at understanding how symptoms of traumatic stress and resilience evolve over time in the University of Minnesota (UMN) healthcare workforce during the coronavirus disease 2019 (COVID-19) pandemic. The study is being conducted concurrently with a UMN peer support program called the MinnRAP program and will remotely administer quality of life and mental health surveys to healthcare workers before they start the MinnRAP program and throughout their participation in the program.
Stress is important for health. As emergency departments (EDs) are often stressful places, a better understanding of the human stress response is important for understanding how and why patients respond as they do when they come to the ED. Since the investigators cannot take up space in the ED for research, the investigators will instead recruit 20 methamphetamine-using participants who are not currently in treatment and 10 healthy adult matched participants to a simulated ED room in the University of Arkansas for Medical Sciences (UAMS) Simulation Center. The investigators will have participants perform a stressor task involving public speaking and a simple arithmetic task. The investigators will see if this experiment can be made to be like being in an actual ED by varying what participants speak about in the task. By doing this, the investigators hope to find out several important things: 1) Is a stressor task feasible and acceptable to participants? 2) What does the stress response -- as measured by cortisol and alpha-amylase -- look like in these participants? 3) Does varying what participants talk about make the experiment seem more like an actual ED? 4) Do participants under stress show even mild symptoms of agitation as measured by clinical scales? If so, how often?
The purpose of this study is to determine the most effective dose of brief, non-invasive brain stimulation (repetitive transcranial magnetic stimulation, rTMS) for improving cognitive functions such as attention and memory as well as to improve the ability to recover from stressful situations (stress resilience).
Stress is a complex natural phenomenon, frequently related to a physiological response, including heart rate, heart rate variability, respiratory rate, skin conductance and temperature. The subjective experience varies greatly; broadly, it may be conceived as a freeze, flight, fight, fright or faint response. Many studies have demonstrated the negative influence of psychological stress on health and well-being. Through the digital phenotyping of physiological and psychological stress reactions, in a controlled laboratory setting (Trier Social Stress Test- TSST) and real-life situations, in a population of healthy participants and patients with a major psychiatric disorder, we expect to find reliable and valid digital biomarkers. The results of this study will, therefore, not only contribute to a better understanding of stress and stress response but also have the potential to improve diagnostic and treatment approaches.
While efficacy of Sudarshan Kriya Yoga (SKY) has been demonstrated in a number of prior studies, little is known about the effects of SKY taught as part of the Your Enlightened Side (YESplus) workshop designed for college students. Thus, this study aims to assess the effects of YESplus on well-being, including sleep patterns, and physiological stress response.
The objective of this study is to apply a rigorous experimental design to test whether children's interactions with therapy dogs increase immediate prosocial behavior and reduce immediate biological response to stress.
Despite increased access to early detection and the availability of more effective therapeutic strategies, African American women continue to experience excess rates of morbidity and mortality from breast cancer. An emerging hypothesis about breast cancer disparities is that social conditions and physiological responses to social stressors influence biological processes that are important to the initiation and progression of disease. This hypothesis is based on data from animal studies which have shown that rats that are exposed to social stressors such as isolation are likely to develop mammary tumors that are histologically and etiologically similar to those that develop among African American women. The HPA axis plays a central role in regulating the physiological stress response; dysregulation of the HPA has been suggested as a mechanism through which social and biological factors contribute to racial disparities in breast cancer outcomes. Many African Americans experience stressful life events and circumstances, including economic, discriminatory, and other stressors. These social factors may contribute to an increased risk of advanced stage disease, but not all African American women who are exposed to adverse social factors develop advanced stage disease and those who have a limited number of psychosocial stressors can develop advanced stage breast cancer, regardless of early detection. This may be because stress reactivity, or one's physiological and psychological responses to a stressor, is highly individualized and dependent on psychological and social determinants as well as genetic factors. But, these biological and psychosocial pathways have not been examined among women at increased risk for disparities. Therefore, this study will characterize stress reactivity and emotional regulation among African American breast cancer survivors and measure the association between these responses and decisions about cancer control and treatment compliance. As part of providing empirical data on biological and psychological pathways that contribute to breast cancer disparities, the investigator's study will identify novel intervention targets that can be used to improve self-management in a population that is at risk for limited cancer control.
Cheer leading is a rapidly growing international sport known for its acrobatic skills and dangerous stunts. The sport presents ample risk for physical trauma, and it is common for athletes to miss extensive time from cheer leading due to injury. The goal of this study is to the see whether the investigators can reduce injury risk among cheer leading athletes by teaching them stress-coping skills to help them relax and reduce their sport-related stress. There exists a link between high levels of stress and increased rates of injury among athletes. When individuals become stressed during athletic events such as competitions or strenuous training, symptoms including muscle tension and narrowed attention often accompany the stress response, increasing injury risk and reducing performance quality. In this study, half of Western University's coed cheer leading team will participate in a six-session stress management intervention to teach them relevant psychological stress-coping skills. Such skills include relaxation breathing techniques, visualization exercises, stoppage of negative thoughts, and development of self-efficacy statements. The other half of the team will receive a placebo "sport nutrition" program. The sessions of both the control program and the stress-management intervention will be administered over the most intensive period of the cheer leading season, from September to November of 2019. The investigators predict that the intervention group athletes will report less cheer leading time missed due to injury, report less sport-related stress, and make fewer errors at their cheer leading championship than their teammates in the placebo group. This is the first study to administer a psychological injury-prevention intervention to cheerleaders.
In this feasibility study the investigators are using a setup of stress-related body sensors including established as well as innovative sensor-based measures to identify predictor profiles for alcohol-related behavioral and neural measures in Alcohol Use Disorder (AUD). 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.
