The main purpose of research is to examine and understanding the development of hypertension in obese adults with insulin resistance. Findings from our studies will identify unique mechanisms that can be targeted to limit increases in vascular dysfunction and reduce the excessively high prevalence of hypertension and risk for cardiovascular disease (CVD). This study is testing the health of the blood vessels and the activity of the nerves that control the blood vessels in adults with insulin resistance. The extent to which ascorbic acid (Vitamin C) improves the function of the blood vessels will be determined. The primary outcome is blood pressure, which is the result of blood vessel health and activity of the nerves, and the reduction in blood pressure that is observed with ascorbic acid. Read Less

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. Read Less

The goal of this study is to learn how long-term use of estrogen affects blood vessels in healthy adults who were assigned male at birth. Participants will: give one blood draw of 5 mL have a camera placed under the tongue to take pictures of blood vessels have 2 laser Doppler microdialysis catheters placed on the forearm to monitor blood vessels before and after local drug infusion Researchers will compare blood vessel function of those who take estrogen supplements to those who do not.

The purpose of this study is to determine if exercise preconditioning can mitigate the off target effects of chemotherapy treatment on measures of cardiovascular function, inflammatory responses, and quality of life. Read Less

This study aims to identify the influence of social determinants of health domains on vascular function in a low income, racial, and ethnic minority population at risk for disparities. We hypothesize that individuals of a lower social economic position and those struggling with depression are at greater risk of cardiovascular disease. Read Less

Atherosclerosis in the setting of HIV infection is distinct and includes increased vascular inflammation, worsened endothelial function, and a predominance of non-calcified plaque. These outcomes can be assessed using specialized noninvasive imaging which strongly predict future CV events in the general population. PCSK9 has emerged as an important pharmacologic target for cholesterol lowering in the general population and recent studies among individuals without HIV have shown that PCSK9 inhibitor therapy is safely tolerated and significantly reduces major CV events in the general population. The investigators will perform a clinical trial of PCSK9 inhibition in the setting of HIV infection. This will be a randomized, placebo-controlled study to evaluate the effects of PCSK9 inhibition on vascular inflammation, endothelial function, and non-calcified plaque using a PCSK9 inhibitor called alirocumab. This study will recruit 140 treated individuals with HIV who are aged 40 and older, with known CVD or risk factors for CVD and who have evidence of vascular inflammation at baseline. The primary and secondary objective of this study is to determine whether PCSK9 inhibition can improve arterial inflammation as assessed by FDG-PET/CT and endothelial function as assessed by flow mediated vasodilation. The investigators will correlate changes in arterial inflammation and endothelial function with lipids and markers of inflammation and immune activation. The tertiary objective is to perform a pilot evaluation of the impact of PCSK9 inhibition on non-calcified plaque as measured by coronary CT angiography. Non-calcified plaque measurements will be correlated with changes in lipid parameters and markers of inflammation and immune activation. Read Less

This is a randomized placebo-controlled study in treated and suppressed HIV-infected individuals aged ≥40 years with either known CVD or 1 CVD risk factor to study the effect of Bempedoic acid (BA) on safety, arterial inflammation as assessed by FDG-PET/CT, lipids, inflammation, immune activation, cardiometabolic indices, and non-calcified plaque (NCP) in the coronary arteries (assessed by coronary CT angiography, CCTA). This trial will be enrolled at UCSF and UCLA. Collaborators at Massachusetts General Hospital (MGH) will serve as the core facility for imaging. Read Less

This project will investigate the effect of spinal cord transcutaneous stimulation on blood pressure in individuals with a chronic spinal cord injury who experience blood pressure instability, specifically, orthostatic hypotension (a drop in blood pressure when moving from lying flat on your back to an upright position). The main questions it aims to answer are: What are the various spinal sites and stimulation parameters that normalize and stabilize blood pressure during an orthostatic provocation (70 degrees tilt)? Does training, i.e., exposure to repeated stimulation sessions, have an effect on blood pressure stability? Participants will undergo orthostatic tests (lying on a table that starts out flat, then tilts upward up to 70 degrees), with and without stimulation, and changes in their blood pressure will be evaluated.

The goal of this clinical trial is to evaluate the effect of transcutaneous spinal cord stimulation on blood pressure in individuals with an acute spinal cord injury (within 30 days of injury). Blood pressure instability, specifically orthostatic hypotension (a drop in blood pressure when moving lying flat on your back to an upright position), appears early after the injury and often significantly interferes with participation in the critical rehabilitation time period. The main questions it aims to answer are: Can optimal spinal stimulation increase blood pressure and resolve orthostatic symptoms (such as dizziness and nausea) when individuals undergo an orthostatic provocation (a sit-up test)? Optimal stimulation and sham stimulation (which is similar to a placebo treatment) will be compared. What are the various spinal sites and stimulation parameters that can be used to increase and stabilize blood pressure to the normal range of 110-120 mmHg? Participants will undergo orthostatic tests (lying on a bed that starts out flat and then moved into an upright seated position by raising the head of bed by 90° and dropping the base of the bed by 90° from the knee) with optimal and sham stimulation, and their blood pressure measurements will be evaluated and compared.
