Feasibility of Breathwork Intervention With Older Adults After Knee Surgery

Postoperative complications after surgical procedures, including following total knee arthroplasty (TKA), have a negative impact on the health and well-being of surgical patients. Older adults (≥65 years) are particularly vulnerable to postoperative complications and their associated morbidities due to the biological aging process. Older adults comprise nearly half of surgical patients worldwide, and this number is expected to increase in the next 10-20 years as the aging population continues to grow. TKA is the most common procedure undergone by older adults, and the rate of TKA procedures is also expected to rise. Despite perioperative guidelines and protocols to prevent postoperative complications, the prevalence of postoperative complications following TKA is approximately 12%. Given these statistics, millions of older adults undergoing TKA may be at risk for postoperative complications and their associated morbidities in the coming decades. Therefore, additional interventions are needed to combat postoperative complications in this population. The body's natural response to surgery, also known as the surgical stress response (SSR), contributes to postoperative complications through complex mechanisms involving the autonomic nervous system (ANS). Increased sympathetic nervous system (SNS) activity, or the body's fight-or-flight response, causes dysregulation in feedback systems that regulate the stress response, potentially leading to poorer outcomes. Interventions, such as breathwork, that induce the parasympathetic nervous system (PNS), or the body's rest-and-digest response, have been shown to balance the ANS, regulate stress biology, and improve outcomes. This study will examine the feasibility of adding a breathwork intervention (Box Breathing), compared to an attention control, to standard perioperative care for older adults undergoing TKA. This study will also examine the proof of concept that Box Breathing, compared to an attention control, may help regulate the SSR by assessing an objective measure of stress-related biology, diurnal cortisol rhythm, and gathering self-report information on pain, anxiety, depression, and quality of recovery following TKA.

The Human Stress Response in a Simulated ED Setting

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?

Feasibility of the 5-Step Method in the U.S.

The purpose of this study is to see if it is possible (feasible) to introduce a behavioral intervention for family members affected by a relative's misuse of drugs and/or alcohol in the United States. The intervention is called the 5-Step Method. It will be a randomized control trial, with a total of 36 participants, and 18 in each group. The study lasts for approximately 12 weeks for the participant. The intervention group will receive a self-help handbook of the 5-Step Method, and the control group will not. Although the control group will not receive an intervention from the research team, they are allowed to look for and use any currently available program for affected family members (for example, Al-Anon, or Nar-Anon) during the study period. The study is being done because the 5-Step Method has not been used or evaluated in the U.S. (or the creators are unaware that it is in use here). There are two aims (objectives): (1) to see if it is feasible to introduce the 5-Step Method into the U.S.; (2) to look at trends in the baseline and followup survey scores to see if there is evidence of preliminary participant response.

Oklahoma Study of Native American Pain Risk III: Stress and Resilience

The goal of this observational study is to learn about the relationship between environmental structural racism and discrimination and chronic pain risk in Native American adults. The main questions it aims to answer are: 1. How does environmental structural racism and discrimination affect chronic pain-promoting mechanisms in Native Americans? 2. What psychosocial factors buffer the negative effects of environmental structural racism and discrimination on chronic pain-promoting mechanisms?
