Older people with HIV (OPWH) are disproportionately impacted by cardiovascular disease (CVD) attributable to behavioral risk factors, and chronic HIV immune dysregulation resulting inflammation. Systemic inflammation is exacerbated by psychological distress via activating the immune response and driving pro-inflammatory CVD risk behaviors. There is promising evidence to suggest that mindfulness could be an effective intervention to reduce psychological distress and support behaviorally- and inflammatory-mediated CVD risk reduction. This project aims to refine and synthesize mindfulness and behavior change content from evidence-based protocols (mindfulness-based stress reduction and diabetes prevention program) to develop and pilot test a new text message-enhanced intervention called "One Mind One Heart" (OM-OH) using feedback from semi-structured interviews with OPWH in psychological distress (N=20), and my multidisciplinary mentorship team (Aim 1). An open pilot (N=5) with exit interviews and pre-post self-report assessments, will inform the initial acceptability of OM-OH and further refine OM-OH as needed (Aim 2). Finally, a pilot randomized controlled trial (RCT; N=50) will be conducted to a.) evaluate benchmarks of feasibility and acceptability of study methods and refined OM-OH compared to enhanced usual care, and b.) investigate potential for effects on psychological distress, inflammation, and behavioral CVD risk (Aim 3). Findings will provide the foundation for an R01 application to conduct an efficacy trial of OM-OH to reduce inflammatory-mediated CVD risk among OPWH.

The goal of this investigational study is to develop algorithms that predict human response to foods. The main question it aims to answer are: - How does varying foods and eating patterns impact one's biological and physiological responses? - In what ways can novel dietary assessment measures be used to improve dietary assessments and to prescribe assessments to people in future research with increased precision? - Can artificial intelligence and machine learning techniques be combined to prescribe foods and eating patterns to individuals for optimization of their health? There are 3 Modules participants may take part in: - Module 1- A participant's dietary intake and accompanying nutritional status, biological and other measures will be observed over 10 days, as well as physiological responses to a liquid mixed meal tolerance test will be measured. - Module 2- Participants will undergo three controlled dietary interventions provided for 14-days each and separated by washout periods of at least 14 days. Physiological responses following a diet-specific meal test will be measured. - Module 3- Participants will undergo the same three dietary interventions during the same 14 day periods as Module 2 while being studied in-residence. Physiological responses following a liquid mixed meal tolerance test and a diet-specific meal test will be measured.

Perioperative fasting has historically been viewed as a low-risk intervention. However, preliminary data indicate that perioperative loss of nutrition and fluids is likely harmful. This study intends to characterize perioperative fasting practices and their potential effects on clinical outcomes through possible effects on patient well-being (anxiety, hunger, thirst), physiology (hypovolemia, hypotension), perioperative aspiration, etc. We hypothesized that in addition to known adverse effects on patients' well-being, prolonged preoperative fasting adversely affects circulating blood volume-related (hypotension, decreased urine output etc.) and glucose metabolism-related (e.g., hypo/hyperglycemia) perioperative physiology. Additional knowledge on the potential adverse effects of preoperative fasting will inform preoperative fasting policies and research interventions that are relevant to hundreds of millions of patients subjected to preoperative/preprocedural fasting worldwide each year.
