Cardiometabolic Syndrome

The purpose of this study is to find out if receiving education regarding increased risks of cardiometabolic disease helps subjects understand these risks and how these risks participants' health.

Cardiovascular disease, type 2 diabetes mellitus and associated diseases combined are the leading health burden and cause of mortality worldwide; therefore, the necessity for an intervention is paramount. Dietary interventions to improve cardiometabolic health are highly sought after as they possess less risk than pharmacological drugs. It has been postulated that Quercetin may be beneficial in improving cardiometabolic outcomes. However, to date, no research has explored this using a placebo randomized intervention.

The increasing prevalence of obesity, its serious health consequences, and the substantial economic burden on healthcare systems underscore a pressing need for effective, long-term prevention strategies that can be implemented in primary care. Emerging evidence suggests that combining lifestyle modification with dietary supplements and pharmacological treatment may enhance and prolong intervention effects, yet comparative long-term data on their individual and combined efficacy are limited. Therefore, this study aims to evaluate the independent and additional effects of a comprehensive lifestyle intervention, a mushroom-based dietary supplement, and bupropion treatment over 12 months, to identify more effective and sustainable strategies for obesity prevention in overweight and obese adults.

Recently a dietary recommendation of 400 - 600 mg/ day has been proposed for the reduced risk of developing cardiovascular disease. Dietary flavanols can be obtained from the intake of foods such as tea, cocoa, wine, berries and apples. Incorporating Chardonnay Marc (the skins and seeds of Chardonnay grapes) into the diet can be an additional source of dietary flavanols. Like other flavanol-rich foods, Chardonnay Marc provides fiber and polysaccharides that may benefit gut health. This study seeks pilot data on the impact of the daily incorporation of Chardonnay Marc powder into the diet on markers of gut and cardiometabolic health.

The overall goal is to examine the efficacy of a circadian intervention in people with overweight and obesity and habitual short sleep duration (HSSD). Participants will undergo a randomized controlled trial, with circadian intervention and control (healthy lifestyle) groups. The circadian intervention is designed to reduce nighttime light exposure and after-dinner snack food intake. Alternatively, the control group will receive basic health information (e.g., physical activity, goal setting, and nutrition when eating out).

Drug-drug interactions often limit statin optimization in a population of patients prescribed cytochrome P3A4 inhibitors, which include immunosuppressive agents, protease inhibitors, and antifungals. These patients frequently have autoimmune conditions or rheumatologic disorders that require complex drug regimens and are often on low-dose statin therapy or no statin at all, resulting in suboptimal LDL levels despite increased cardiovascular (CV) risk. There is an unmet clinical need to improve LDL levels in this vulnerable patient population, which faces increased CV risk due to underlying conditions that also contribute to polypharmacy and multiple drug-drug interactions. This study is a randomized, open-label trial evaluating subcutaneous inclisiran plus standard of care for LDL-C lowering in high-risk primary prevention patients with multiple comorbidities (e.g., Type II diabetes, liver disease, chronic kidney disease, autoimmune disease, solid-organ transplant) who are taking five or more medications in which drug-drug interactions prevent optimization of statin therapy.

The goal of this clinical trial is to test the impact of repeated intermittent short sleep, with short sleep maintained 5 days per week followed by 2 days of prolonged sleep, compared to daily adequate sleep, on energy balance and cardiometabolic risk. A secondary goal of this research is to determine if maintaining a constant midpoint of sleep while undergoing intermittent short sleep, leads to better outcomes than intermittent short sleep with a 2-hour delay in sleep midpoint. The aims of this research will be tested in the context of a 3-group, parallel-arm, outpatient intervention of 4 weeks in duration, in young-to-middle-aged adults (aged 18-49 years).

The investigator's long-term goal is to mitigate pregnancy-related mortality (PRM) risk by systematically delivering scalable integrated clinical and supportive care that is effective for all. The investigator's central hypothesis is that the Multi-modal Maternal Infant Perinatal Outpatient Delivery System (MOMI PODS) will mitigate postpartum (PP) risk for all by increasing patient engagement with evidence-based cilnical and supportive care, thus improving biopsychosocial profiles that drive clinical risk. To test this hypothesis, the investigators will conduct a hybrid type 1 randomized controlled trial (RCT) of MOMI PODS versus enhanced usual care (EUC, which we will term MOMI CARE) among a total sample of up to 384 mother-infant dyads (192/group) following pregnancy affected by a cardiometabolic and/or mental health condition. The investigators will enroll participants during late pregnancy and collect data at baseline and 6 months and 1 year PP. The investigators will collect implementation and service data across sites.

Cardiovascular disease, type 2 diabetes mellitus and associated diseases combined are the leading health burden and cause of mortality worldwide; therefore, the necessity for an intervention is paramount. Dietary interventions to improve cardiometabolic health are highly sought after as they possess less risk than pharmacological drugs. It has been postulated that Berberine may be beneficial in improving cardiometabolic outcomes. However, to date, no research has explored this using a placebo randomized intervention.

This study is designed to investigate differences between people living with HIV (PLWHIV) and general populations on how the body utilises and stores energy. This study uses magnetic resonance imaging (MRI) to measure fat around the body organs including the heart and liver. The fat around body organs, also known as visceral fat, is known to be associated with metabolic syndrome and a risk factor for developing heart attacks and strokes. MRI scans are used frequently in hospitals to diagnose a range of conditions. These scans use radio waves to measure protons in body tissues. The machines can reconstruct tissues using complex algorithms to form composite images of body structures. MRI scans do not use ionising radiation and there is no risk to undertaking an MRI in terms of radiation. We often use MRI scans to assess the hearts' structure and function. In addition, we can use specific MRI sequences to assess the integrity of heart muscle. Heart MRI is often considered the gold standard imaging technique to assess the heart and heart muscle disease. This sub-study will use multiple MRI sequences to assess the heart and the liver. We are aiming to investigate any changes in heart and liver fat. In addition, we will assess any changes in fat levels within the heart muscle cells whilst also assessing for any change in the way the heart is functioning. PLWHIV have roughly double the risk of heart attacks compared to general populations. Previous studies have demonstrated that this increased risk may arise from the way in which fat is stored and metabolised in the body. We hope this study will give insight into why HIV-positive individuals have increased risks of heart attacks and how reducing visceral fat may reduce risk. It may lead to further medicines or treatment strategies to reduce the risk of heart attacks in HIV-positive individuals.

Latino individuals face an elevated risk of adverse health outcomes during pregnancy, impacting both the birthing parent and the baby with potential long-term chronic health conditions. While promoting a healthy diet during pregnancy is a promising strategy, interventions targeting dietary behaviors have yielded mixed results and lack widespread dissemination in communities in need. Collaborating with community-based organizations could enhance cultural relevance, build trust with Latino families, and improve program reach and effectiveness. Food Education Access Support Together (FEAST) is a community-based program that promotes healthy eating, well-being, and health equity for diverse, under-resourced urban populations in Los Angeles. The newly developed FEAST Perinatal Support Program (PSP) aims to support individuals through pregnancy and postpartum by providing dietary psychoeducation, skill-building, and social support, with an additional component of grocery gift cards to address food access barriers. This study proposes a pilot trial to assess the feasibility and preliminary efficacy of the FEAST PSP in enhancing dietary outcomes, overall health, and socio-cognitive precursors, in pregnant individuals. The study will enroll 40 pregnant adults in a single-arm study who will receive the core PSP with a $15 gift card for healthful fresh food (PSP+giftcard). Pre- and post-intervention assessments will include questionnaires, dietary recalls, physical measurements, and interviews to evaluate program perceptions. Specific aims include evaluating program feasibility and acceptability (i.e., reach, retention, and participant perceptions) and determining preliminary efficacy on changing socio-cognitive and behavioral aspects of diet, self-reported health, and cardiometabolic risk factors. The project aligns with goals of improving health outcomes in Latino families in Southern California and supports FEAST's strategic objectives for improving health and wellness of individuals during pregnancy and throughout the lifespan. The findings will inform program refinement and future NIH grants for rigorous evaluation of the FEAST PSP.

Lower attainment of cardiovascular health (CVH), indicated by the American Heart Association's Life's Simple 7 (LS7; physical activity, diet, cholesterol, blood pressure, body mass index, smoking, glycemia) and Life's Essential 8 (LE8; LS7+sleep) metrics, is a major contributor to Black men having the shortest life-expectancy of any non-indigenous race/sex group. Unfortunately, a paucity of literature exists on interventions aimed at improving CVH among Black men. The team of clinician scientists and community partners co-developed a community-based lifestyle intervention titled Black Impact: a 24-week intervention for Black men with less-than-ideal CVH (\<4 LS7 metrics in the ideal range) with 45 minutes of weekly physical activity, 45 minutes of weekly health education, and engagement with a health coach, group fitness trainer, and community health worker. Single-arm pilot testing of the intervention (n=74) revealed high feasibility, acceptability, and retention and a 0.93 (95% confidence interval: 0.40, 1.46, p\<0.001) point increase in LS7 score at 24 weeks. Secondary outcomes included improvements in psychosocial stress (i.e., perceived stress, depressive symptoms), patient activation, and social needs. Thus, robustly powered clinical trials are needed to determine the efficacy of Black Impact and to evaluate the underlying interpersonal and molecular pathways by which Black Impact improves psychosocial stress and CVH. Thus, the investigators propose a randomized, wait-list controlled trial of Black Impact. This novel, community-based intervention to provide a scalable model to improve CVH and psychosocial stress at the population level and evaluate the biological underpinnings by which the intervention mitigates cardiovascular disease risk. The proposed study aligns with American Heart Association's commitment to addressing CVH equity through innovative, multi-modal solutions.

Positron emission tomography with 18F fluorodeoxyglucose (FDG) is the conventional imaging technique to provide information regarding tissue glucose uptake and has been highly clinically successful. However, it cannot assess downstream metabolism, which may be useful in the diagnosis and assessment of treatment response in a variety of diseases. Patients will also be exposed to ionizing radiation, the amount of exposure can vary depending on the dose of tracer administered, frequency of scans and duration of each scan. Carbon-13 (13C) magnetic resonance imaging (MRI) is particularly attractive for metabolic imaging because carbon serves as the backbone of nearly all organic molecules in the body. With this technique, the polarization increases to approximately 30%-40%, an increase of over 10,000 to 100,000-fold, thereby dramatically increasing the MRI signal . Whilst the role of 13C imaging has been demonstrated in many sites around the world, we aim to demonstrate the feasibility and application of 13C hyperpolarized imaging in healthy Singapore residents and patients with cardiovascular and/or cardiometabolic diseases.

The main purpose of this study is to compare the impact of 12-week moderate-intensity interval training (MIIT) versus combined MIIT with high-intensity interval training (HIIT) on physical fitness, cardio metabolic, lipidomic, hematological and psychological characteristics in young overweight/obese girls.

The Investigators will create a clinical database and a Biobank of stem cells derived from the blood of participants with cardiovascular disease. The Investigators will recruit participants from diverse racial and ethnic backgrounds with equal representation from both sexes. The Investigators expect to create stem cells and analyze the blood for protein biomarkers and genetic causes of cardiovascular disease. The stem cell biobank and clinical data will be a powerful tool for studying cardiovascular disease.

POWER Health is a randomized clinical trial with a two-arm parallel design whose objectives are 1) to study metabolic flexibility and autonomic function (both capacities that describe cardiovascular health) in a sample of postmenopausal oncological women vs postmenopausal untreated controls (CT); and 2) to analyze the impact of two different 8-week physical exercise supervised interventions: HIIT training vs strength training focused on muscle power, on both cardiovascular capacities in these populations.
