The Effects of Fresh Mango Consumption on Cardiometabolic Outcomes in Free-living Individuals With Prediabetes

The goal of this clinical trial is to test the effect of 12 weeks of 1.5 cups per day of fresh mango on glucose control, insulin resistance, lipids, inflammation, oxidation and body composition in individuals with prediabetes. The main questions it aims to answer are: * What is the effect of 1.5 cups per day of fresh mango over 12 weeks on indicators of glycemic control including fasting glucose and HgbA1c? * What is the effect of 1.5 cups per day of fresh mango over 12 weeks on fasting blood insulin and insulin resistance (HOMA-IR)? * What is the effect of 1.5 cups per day of fresh mango over 12 weeks on lipids including LDL-cholesterol, total cholesterol, HDL-cholesterol and triglycerides? * What is the effect of 1.5 cups per day of fresh mango over 12 weeks on oxidative stress including oxidized LDL-cholesterol and 8-iso-PGF2-alpha? * What is the effect of 1.5 cups per day of fresh mango over 12 weeks on markers of inflammation including c-reactive protein, e-selectin, ICAM, VCAM, TNF-alpha and IL-beta? * What is the effect of 1.5 cups per day of fresh mango over 12 weeks on percent body fat, fat mass, and lean mass? Participants will be asked to: * Consume 1.5 cups of mango per day for 12 weeks, take a 4 to 8 week break, and then avoid consuming mangos for 12 weeks * Attend a prerandomization clinic prior to study * Attend three (3) clinics where blood will be drawn during weeks 0, and 12 of the first phase and last week of the second phase of the study * Attend eight (8) clinics where anthropometric measurements (height, weight, body composition) will be conducted and interaction with study clinicians will occur during weeks 0, 4, 8, 12 of each phase of the study * Complete questionnaires and surveys in person and remotely, including six (6) 24-hour dietary recalls. Researchers will compare the 12 weeks participants consume mango to the 12 weeks the participants are not consuming mango to see if there are differences in glycemic indicators, insulin resistance, lipids, inflammation, oxidation and body composition between the two time periods.

Effect of Aerobic Training on the Health Parameters of Postmenopausal Women With Multimorbidity

People affected by multiple chronic diseases have a greater chance of hospitalization, longer hospital stays, worse general health, worse physical and mental function and lower functional capacity, with an average risk of 50% of functional decline with each additional condition. The frequency of multimorbidity is higher in older, inactive women, who live in urban areas in low- and middle-income countries, the most affected by multimorbidity. The practice of physical exercise is an important component in the prevention of multiple chronic diseases, in which lower levels of physical activity were associated with an increased prevalence of multimorbidity in women aged 16 to 24 years. And regardless of the presence of multimorbidity, engaging in a healthier lifestyle, including regular physical activity, was associated with up to 7.6 more years of life for women, improving the individual's general health status even when multimorbid. The hypothesis is that multimorbid women have a worse general health status when compared to women without multimorbidity, but aerobic exercise will be able to improve health parameters in 12 weeks of training. This is a quasi-experimental clinical trial with a 12-week aerobic training intervention in postmenopausal women with and without cardiometabolic multimorbidity. Participants were allocated into groups according to the amount of cardiometabolic diseases, with the Morbidity group (MORB) being composed of women with one or no chronic cardiometabolic disease and the Multimorbidity group (MULTI) with two or more chronic cardiometabolic diseases. The assessments of arterial stiffness, 24-hour ambulatory pressure, blood pressure variability, heart rate variability, lipid and glucose profile, body composition and climacteric symptoms were performed before and after the training period. The study was carried out at the Laboratory of Cardiorespiratory and Metabolic Physiology at the Faculty of Physical Education of the Federal University of Uberlândia, Uberlândia, Brazil and approved by the Ethics Committee for studies in humans (CAEE: 12453719.1.0000.5152). All participants signed a consent form. The experiments followed the principles of the Declaration of Helsinki. The program consists of aerobic physical exercises performed three times a week on non-consecutive days for 12 weeks with an intensity of 65% to 75% of the reserve heart rate.

Effects of a Digital Health Application (Lipodia) on LDL-cholesterol Levels

The goal of this clinical trial is to find out if lipodia, a digital health intervention, can help lower cholesterol levels and improve other health measures in adults with high cholesterol. The main questions it aims to answer are: * Does lipodia, together with regular treatment, lower LDL cholesterol (bad cholesterol) better than regular treatment alone? * Does lipodia help improve other health outcomes, like how confident participants feel in managing their health? Researchers will compare two groups: * Intervention group: Participants use the lipodia intervention and continue their usual treatment. * Control group: Participants continue with their usual treatment only. Participants will: * Fill out questionnaires online and visit a certified lab at the start of the study, after 3 months, and after 6 months * Have blood tests at each lab visit to check their cholesterol and other blood fat levels * Continue with their usual treatment (both groups) and use lipodia, a digital health app, for six months (intervention group only)

Effects of Pitavastatin or Combination of Pitavastatin and Ezetimibe on Glucose Metabolism Compared to AtoRvastatin in atheroscLerotic Cardiovascular Disease Patients With Metabolic Syndrome: The EZ-PEARL Randomized Trial

Taiwanese Green Propolis for Lipid Profiles, Fatigue, and Quality of Life in Oral Cavity Cancer Survivors

This study examined whether Taiwanese Green Propolis (TGP), a natural bee-derived supplement, can improve blood fat levels, reduce tiredness (fatigue), and improve quality of life in people who have completed treatment for oral cavity (mouth) cancer. People who had finished treatment for oral cavity squamous cell carcinoma (a type of mouth cancer) and were in the follow-up period were invited to participate. Participants were randomly assigned to take either 4 TGP capsules per day (2,000 mg/day total) or 4 identical-looking placebo capsules for 12 weeks. Neither participants nor the study team knew who received which capsules until after the study ended (double-blind). All participants were followed for a further 12 weeks after stopping the capsules. At the start and at Weeks 4, 8, 12, and 24, participants had blood tests to measure cholesterol, triglycerides, liver enzymes, and inflammation markers. They also completed questionnaires about fatigue (BFI-T), symptoms (ESAS-r), and quality of life (FACT-H\&N), and performed physical tests including grip strength and a 30-second sit-to-stand test. The study aimed to determine whether TGP can help manage the metabolic and fatigue-related problems common after oral cancer treatment, and to provide data for planning larger future trials. 25 participants were enrolled at a regional teaching hospital in northern Taiwan. Stool and saliva samples were also collected at each timepoint to assess gut and oral microbiota composition (16S rRNA sequencing) and salivary inflammatory markers. Heart rate variability was monitored via smart wristband (minimum 24 hours per timepoint).

Uppsala Self-Screening of Cardiovascular Health

U-SCREEN is a randomized controlled trial evaluating whether systematic home-based multimodal screening for cardiovascular risk conditions, offered to residents in Region Uppsala turning 50, 55, 60, 65, 70 or 75 years of age, can identify clinically actionable cardiovascular risk factors more effectively than usual care. Participants randomized to the screening arm receive a home blood pressure measurement device, a dried blood spot sampling kit (for ApoB, HbA1c and creatinine), and a digital questionnaire. The control arm receives usual care. Recruitment runs 2024-2027 with a target identification of 10,000 cardiovascular risk conditions.

Nudging Preventive Screening Via Message Framing and Bundling

This study is a randomized controlled field experiment embedded in the medical institution Early Diagnosis Program in Chile. Participants with two exams pending (a cancer screening test and a chronic disease test for diabetes and dyslipidemia) will be randomly assigned across a 3 × 3 factorial design: three message framing conditions (Basic, Risk/Importance, Peace of Mind) crossed with three exam-type conditions (cancer screening only, chronic disease test only, or both exams). Participants with only a cancer screening pending will be assigned to the 3 framing conditions and be encouraged to get the cancer screening. In both cases, participants are assigned to each experimental arm at twice the rate of an additional arm receiving the standard message currently used by the medical institution. This standard-message arm is included for operational purposes, is not part of the pre-specified analyses, and is thus not described in the "Arms and Intervention" section (or counted for "number of arms").

Randomized Controlled Trial of Alert-Based Computerized Decision Support for Patients With Peripheral Artery Disease Not Prescribed Lipid-Lowering Therapy

This single-center, 400-patient, randomized controlled trial assesses the impact of a patient- and provider-facing EPIC Best Practice Advisory (BPA; alert-based computerized decision support tool) to increase guideline-directed utilization of statin and statin-alternative oral LDL-C lowering therapies in patients with PAD who are not being prescribed LDL-C-lowering therapy.

Generative AI for Medication Counselling and Adherence in Community Pharmacies

Medication counseling within community pharmacies is crucial for managing chronic diseases, yet significant challenges regarding correctness and completeness remain in Jordan. Although generative artificial intelligence (AI) can be utilized for patient education, there is a lack of research on clinical impact and safety of AI in medication counseling conducted by pharmacists in real-world practice. The aim of this study is to evaluate the effect of pharmacist-supervised AI-assisted medication counseling on the correctness and completeness of counseling information and 30-day medication adherence among patients in Jordanian community pharmacies.

Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of MWX205

This study is being done to test a new injection called MWX205 in people with high cholesterol or fat levels in the blood (dyslipidemia). Researchers will check if a single dose of MWX205 is safe and how the body reacts to it. They will also measure how quickly the drug enters the bloodstream and how long it stays in the body, and compare it with a placebo (inactive treatment). The study will help decide the right dose and understand how this medicine could be used in future treatments. The main questions this study aims to answer are: 1. Is MWX205 safe after a single dose? 2. How does the body process MWX205? 3. Does MWX205 show any effect on the body related to cholesterol levels?

A Safety and Tolerability Trial Evaluating CTX310 in Participants With Refractory Dyslipidemias

Effects of Nattokinase on Inflammation and Cardiovascular Risk Markers in Patients With Dyslipidemia

The study aims to evaluate the effect of the nattokinase enzyme on inflammation and markers of cardiovascular risk in participants with dyslipidemia. A longitudinal double-blind randomized clinical trial will be carried out, involving hypertensive participants with dyslipidemia for two months.

Effects of Phytosterol Supplementation on Liver Function and Inflammatory Status in Patients With Nonalcoholic Fatty Liver Disease

Non-alcoholic fatty liver disease (NAFLD) is considered one of the most common chronic liver diseases worldwide, it recently became a worldwide problem with high morbidity which requires further attention. The use of natural bioactive products such as phytosterols have shown anti-NAFLD effect with little to no side effects when used as a supplement in the therapeutic protocol of NAFLD, in many animals, and In vitro studies. Although the positive impacts of phytosterols on the prevention of hypercholesterolemia and improving liver functions have been reported in previous studies, further clinical experiments, especially human studies are needed to assure the effectiveness of phytosterols on improving liver enzymes, lipid profile, and insulin response in patients with NAFLD. In this study, we focus on the efficacy of phytosterol in a dose similar to the therapicutic lifestyle changes diet (TLC) recommendation with an aim to include it in the therapeutic protocol for NAFLD and to study the effect of some confounders that were excluded in previous studies on this relationship.

Psychosocial, Environmental, and Chronic Disease Trends in Puerto Rico

The overall goal is to identify trends and longitudinal associations in psychosocial, food-related, and cardiometabolic risk factors that can guide public health priorities and future research needs aimed at reducing cardiovascular-related disparities in Puerto Rico. To this end, investigators will establish 'PROSPECT: Puerto Rico Observational Study of Psychosocial, Environmental, and Chronic disease Trends', an island-wide, longitudinal population cohort of 2,500 adults (30-75 years) in PR recruited with a community-wide sampling strategy, and assessed in a network of several partner clinics across the island. The study will collect comprehensive data on multiple psychosocial, dietary, and food-related factors, CVD biological markers, and medical record data, with follow-up at 2-years, and will assess variations by urban-rural area and by timing before-after Maria.

Atmeg (Atorvastatin and Omega-3 Combination) and Carotid Atherosclerosis in Patients With Type 2 Diabetes and Combined Dyslipidemia

This is a randomized controlled study to assess the effect of atorvastatin and omega 3 combination therapy compared with atorvastatin and ezetimibe combination therapy in Korean T2DM patients with asymptomatic atherosclerosis.

Cottonseed Oil Dose Response

Adding cottonseed oil to the diet has been shown to improve cholesterol profiles and other markers of chronic disease risk in both healthy and at-risk adults. However, CSO has only been tested in the context of high-fat diets. The goal of this clinical trial is to learn about the health effects of lower amounts of cottonseed oil (CSO) added to the diet in adults at increased risk for cardiovascular disease. The main questions it aims to answer are: * How do different amounts of CSO in the diet affect fasting cholesterol profiles and markers of liver function? * How do different amounts of CSO in the diet affect fasting and post-meal markers of lipid metabolism (i.e. triglycerides) and glycemic control (i.e. blood sugar and insulin)? * How do different amounts of CSO in the diet affect fasting and post-meal markers of chronic disease risk factors such as oxidative stress, inflammation, coagulation potential, and appetite control? Participants will be asked to: * Consume provided breakfast shakes and snacks daily for 28-days. * Attend three weekly short visits for fasting blood draws, body measurements, and collect the next week of study materials. * Attend two longer (5.5 h) testing visits which include eating a standardized breakfast meal and having blood drawn periodically before and after breakfast. Researchers will compare CSO LOW, CSO MID, CSO HIGH, and Control groups (receiving a mixture of oils) to see if lower doses of CSO in the diet impart the same health benefits as previously shown with high doses of CSO.

Impact of Phytosterol-Rich Extract on Lipid Profile

The aim of this randomized, parallel, two-arm, placebo-controlled, triple-blind clinical trial is to evaluate the efficacy of a phytosterol- and phytostanol-rich extract on lipid profile parameters in individuals with hypercholesterolemia, focusing primarily on total cholesterol and LDL cholesterol levels.

Dose Response Effects of Pecan Consumption

The bioactive compounds contained in tree nuts have been shown to beneficially affect cardiometabolic health outcomes. Pecans contain more total phenols, sterols, and flavonoids than any other tree nut. They also are a rich source of polyunsaturated fatty acids (PUFAs), fiber, vitamin A, vitamin E, folic acid, calcium, magnesium, phosphorus, potassium, and zinc. These bioactive components in pecans are likely the reason for the previously documented improvements in cardiometabolic health. The specific aims of this study are to: * Examine the effect of pecan consumption at doses of 6%, 13%, and 20% of total energy needs on fasting and postprandial blood lipids. * Examine the effect of pecan consumption at doses of 6%, 13%, and 20% of total energy needs on plasma markers associated with overall health. * Examine the effect of pecan consumption at doses of 6%, 13%, and 20% of total energy needs on subjective and physiologic postprandial measures of hunger and satiety. Participants will be asked to: * Consume pecans daily for 28 days or maintain their current habitual diet. * Attend three short weekly visits for fasting blood craws, body measurements, and collect their next week's supply of study materials. * Attend two longer (5 h) testing visits which include consuming a standard breakfast meal and having their blood drawn periodically before and after breakfast. Researchers will compare pecan LOW, pecan MID, pecan HIGH, and the Control group to examine the physiologic effects of incorporating various dosages of pecans into one's diet.

Prevalence, Incidence and Risk Signature of Chronic Kidney Disease in Sub-Saharan Africa

Chronic kidney disease (CKD) is associated with increased cardiovascular morbidity and mortality. The prevalence of CKD is increasing worldwide and is assumed to also dramatically increase in Sub-Saharan Africa (SSA). Key shortcomings of available data on CKD in SSA are as follows: (i) Available data are based on single measurements and, therefore, cannot distinguish between harmless transient deterioration in kidney function and chronic kidney damage; (ii) Accurate information regarding renal protein loss, an important and early marker of kidney disease, is lacking; (iii) Cardiovascular risk factors for CKD, such as obesity, hypertension and diabetes, are often not searched for. Likewise non-classic potential risk factors, such as endemic infectious diseases, socioeconomic status and lifestyle have not been consistently recorded; (iv) Information to interrogate linked interaction over time between risk factors and development of CKD is unavailable. With this project, situated in a region representative of semi-rural SSA, we aim to fill this knowledge gap and (i) establish guideline conform prevalence data of CKD and its major cardiovascular risk factors, as well as (ii) prospectively define the incidence of cardiovascular- and non-classic risk factors of CKD. The data from (i) and (ii) is used to develop predictive models. A prospective cohort of 1200 individuals in a primary care facility will serve as study population. The population is representing a society in transition from rural to more urban lifestyle. In the pilot study, participants will be followed for one years and undergo the clinical and biomedical testing required to capture CKD and its classic and non-classic risk factors over time.

Cluster Randomized Trial of a Digital Quality Improvement Intervention on LDLCholesterol Control

Elevation in low density lipoprotein (LDL) cholesterol (LDL-C) is a causal risk factor for atherosclerotic established cardiovascular disease (ASCVD). Reduction of LDL-C with statins has been clearly demonstrated as a robust and cost-effective way of reducing the burden of ASCVD in individuals at risk. ASCVD is the leading cause of death and disability in Brazil and therefore prevention guidelines recommend LDL-C reduction with the aim of reducing disease burden in individuals at risk. Studies have shown a clear hiatus on awareness and treatment of cholesterol in Brazil. Thus, it became imperative to develop knowledge translation projects aiming at bridging the gap between science and clinical practice and ultimately leading to better outcomes. Cluster randomized clinical trials are the highest quality type of clinical research to test educational and active interventions aimed at changing behaviors or clinical practices. Therefore, this study is a pragmatic cluster randomized trial to assess the effect of a digitally enabled quality improvement intervention on LDL-C control in atherosclerotic established cardiovascular disease (ASCVD) patients.

In the project, sedentary males at different stages of dysglycemia living in the city of Bialystok participate in three months of an exercise intervention consisting of supervised training sessions at a local fitness centre. The aim of the study is to assess the effectiveness of the exercise intervention in patients at different stages of dysglycemia progression, including type 2 diabetes and prediabetes and compare the response between groups.

A Study of LY3885125 in Participants With Dyslipidemia or Non-Alcoholic Fatty Liver Disease (NAFLD)

The main purpose of this study is to evaluate the safety and tolerability of LY3885125 after administration of single ascending doses in participants with dyslipidemia (part A) and multiple doses in participants with non-alcoholic fatty liver disease (part B). Blood tests will be performed to check how much LY3885125 gets into the bloodstream and how long it takes the body to eliminate it. The study will last up to approximately 49 weeks for part A and 62 weeks for part B, for a total of approximately 111 weeks.

Dachundou No Sugar Added Soymilk for Lipid Modulation

Cardiovascular disease is one of the leading causes of death worldwide, and high cholesterol is a major risk factor. Diet is known to play an important role in managing blood lipids. Soy milk is a common plant-based drink rich in protein and isoflavones, which may help lower cholesterol and improve heart health. This clinical trial will evaluate whether daily consumption of Dachundou No Sugar Added Soymilk can help reduce cholesterol levels in adults with elevated total cholesterol (≥200 mg/dL). A total of 50 participants aged 18-65 will be recruited. Participants will drink two bottles of soymilk per day (375 mL each, total 750 mL) for 8 weeks. During the study, researchers will measure cholesterol, blood pressure, body weight, waist circumference, and other health indicators. The results will help determine whether Dachundou No Sugar Added Soymilk can improve blood lipid levels and contribute to cardiovascular health.
