Effects of SugarCut® Unripe Guava Fruit Extract on Blood Glucose Regulation

Start date: March 2024
Phase: N/A
Study type: Interventional

Guava (Psidium guajava) belongs to the Myrtle family. It is a tropical and subtropical fruit native to the Americas. Ripe guava fruit is sweet and delicious. It is rich in vitamins A, C and trace elements such as phosphorus, calcium and magnesium. In traditional medicine, guava fruit can be eaten raw, and the roots can treat stomach problems, abdominal pain, dysentery, and diabetes; the leaves can treat diabetes, abdominal pain, rheumatism, antipyretic, stomachache, anthelmintic, cholera, vomiting, diarrhea, enteritis and other symptoms. Guava leaf extract contains polyphenols. Studies have shown that guava leaf has antioxidant, blood sugar regulating and anti-cancer effects. Not only guava leaves, research has found that guava fruits are rich in vitamins, fiber and antioxidants, which have anti-inflammatory and anti-cancer effects. Preliminary research has found that the extract of red guava young fruit has more active ingredients - saponins and total polyphenol content, and its antioxidant capacity is also higher than that of mature guava. In vitro studies have found that guava fruit extract can increase the expression of GLUT4 gene and promote the entry of blood sugar into cells. At the same time, guava fruit extract can inhibit the formation of final glycated proteins (AGEs). The purpose of this study is to explore the effect of guava fruit extract on blood sugar regulation in humans and to evaluate its potential to be developed as a blood sugar regulation supplement.

Effects of Coffee Consumption on Metabolic Markers in Adults With Prediabetes and Obesity

Start date: February 5, 2024
Phase: N/A
Study type: Interventional

Epidemiological studies have shown an inverse association between coffee consumption and risk of type 2 diabetes. However, the randomized controlled trials in prediabetes are limited to evaluate the effects of coffee. The purpose of this study is to investigate the effects of coffee on metabolic factors and inflammation in individuals with prediabetes and obesity. A double-blind, randomized controlled trial is designed to explore the effects of coffee consumption on participants with prediabetes and obesity. A total of 100 eligible participants with prediabetes and obesity will be recruited from the Health Management Center of Nanjing First Hospital. These participants are randomly assigned in a 1:1 ratio to either the coffee capsule group or the control group. The coffee capsule group will be instructed to consume 3.6 g of coffee capsules per day (0.3 g per capsule, 6 capsules per serving, twice a day, once in the morning and once in the middle of the day). The control group will be asked to consume 3.6 g of cornstarch capsules (0.3 g per capsule, 6 capsules per serving, twice a day, once in the morning and once in the middle of the day). 75 g oral glucose tolerance test, 2-week blinded continuous glucose measurement and others will be performed before and after the 3-month intervention. During the three months of intervention, the information on dietary intake, physical activity and sleep of participants will be systematically collected. To comprehensively assess the impact of coffee intake on prediabetes and obesity, we will analyze the effects of coffee capsules on various metabolic and inflammatory markers, including glucose metabolism, lipid profiles, blood pressure, adiponectin, high sensitivity C-reactive protein, interleukin-6, body mass index, body composition, the degree of hepatic steatosis and so on. We will further adjust for potential confounding factors such as lifestyle factors to better understand the underlying biological mechanisms driving this association.

NCT ID: NCT06322940 Not yet recruiting - Clinical trials for Overweight and Obesity

Effect of Dairy Product Matrices on Insulin Resistance in People With Overweight and Obesity and Prediabetes

Start date: September 1, 2024
Phase: N/A
Study type: Interventional

The objective of the study is to determine the effect of dairy product matrices on insulin sensitivity in overweight and obese adults with prediabetes. Females and males (30-65 y) will be recruited from the greater Montreal area. Upon screening, those with prediabetes will complete a 2-wk run-in period in which participants will consume 1 serving/d of regular-fat dairy products (milk, yogurt, or cheese). Adherent participants will be randomized by sex into 1 of 3 groups: ≤1 serving/d of dairy (limited dairy) or 2-3 servings/d of reduced-fat or regular-fat dairy for 12 weeks. Participants will be instructed on how to incorporate foods into their diet to prevent changes in their body weight. The hyperinsulinemic-euglycemic clamp will be used before and after the intervention to document potential changes in insulin sensitivity as the primary outcome. In addition, glycemic variables, body composition, and cardiometabolic risk factors will be assessed as secondary outcomes. Adherence to intervention will be assessed at each visit by food diaries and a record of consumed dairy products.

Hydroxytyrosol Dietary Supplement and Prevention of Age-Related Diseases

HYTOLIVE15
Start date: March 2024
Phase: N/A
Study type: Interventional

The primary objective of this study is to ascertain the effects of chronic consumption of a hydroxytyrosol-rich extract from olive (Hytolive®) in a population at high risk of developing age-related pathologies such as type 2 diabetes and cardiovascular diseases. The markers measured will be associated with oxidative stress, inflammation, and homeostasis glucose and lipid profiles. Improvements in these parameters could potentially prevent the onset of pathologies associated with aging.

NCT ID: NCT06292000 Recruiting - Obesity Clinical Trials

Examining the Effects of Morning and Evening Exercise on Glucose Regulation in Adults With Prediabetes

TExIS
Start date: February 1, 2024
Phase: N/A
Study type: Interventional

Purpose of the Study: This study is to learn more about how exercising at different times of the day (morning versus evening) affects metabolism of glucose in the body, sleep, activity outside of exercise, and other factors. Procedures: - 2 screening visits to make sure you are eligible to be in the study. This will include a fasting blood draw and heart tracing (EKG). - If you are eligible, you will complete both exercise conditions in a random order. All participants in the study will complete the following separated by 3-4 weeks: - Baseline condition of NO exercise - Morning exercise for 3 days in a row - Evening exercise for 3 days in a row - You will be provided with an example diet to follow for the days you are completing the baseline and exercise conditions (three days total for each condition). This diet will be a "traditional" diet with a controlled amount of carbohydrates, protein, and fat per day. The investigators will provide you with examples of meals to eat during this time. - You will be asked questions and complete questionnaires about your health history, sleeping and awakening habits, and sleepiness levels. - You will undergo one x-ray scan to measure your level of body fat. - You will be asked to wear an activity monitor and sleep monitor for 6 days in a row three times during this study. - You will be asked to wear a continuous glucose monitor (CGM) for 6 days in a row three times during this study. - You will be asked to measure your saliva melatonin levels three times in the study. This will be done once per hour for 5 hours (a total of 6 saliva samples). - You will be asked to complete a procedure called a "hyperinsulinemic-euglycemic clamp" where you will have an IV placed and insulin and glucose infused with frequent lab and finger stick blood sugars monitored closely. This will be done 3 times during the study.

Weight Inclusive and Adaptive Strategies to Enhance Cardiometabolic Health in Black Adults

WISE Health
Start date: May 1, 2024
Phase: N/A
Study type: Interventional

The proposed 6-month pilot Sequential Multiple Assignment Randomize Trial (SMART) has two aims. The first and primary aim is to determine the feasibility of conducting a full-scale SMART to compare weight-focused (i.e., weight loss) and weight-neutral (i.e., weight loss is not an explicit goal) adaptive biobehavioral interventions for improving cardiometabolic health in Black adults with overweight or obesity (BMI ≥27 kg/m2) plus at least one weight-related cardiometabolic condition (high blood pressure, prediabetes or diabetes, and/or high cholesterol). Biobehavioral interventions are treatment strategies that combine lifestyle-based behavioral interventions such as eating a healthy diet and exercise with medications. In this study, participants will be randomly assigned to receive either weight-focused or weight-neutral health coaching for 7 weeks. At week 8, participants will be identified as either "responders" or "nonresponders" to the initial interventions. The threshold for response in the weight-focused condition is greater than or equal to 3% weight loss. The threshold for response in the weight-neutral condition is engaging in greater than or equal to 150 minutes of moderate physical activity for the 7 days prior to the week 8 study visit. Responders to the initial interventions will continue with health coaching on a biweekly basis for weeks 9-26 of the intervention. Nonresponders will be re-randomized to either intensify the lifestyle-based intervention by receiving a membership to the YMCA and enrolling in group fitness classes or augmenting the health coaching with enhanced medical management in partnership with their established primary care provider. The second aim is to use clinical data from the pilot SMART to estimate treatment effects and the between-person variability in these effects. Because this is a pilot study, these estimates will not be used to make comparisons or draw conclusions on the comparative effectiveness of intervention conditions. Rather, these data will be used to generate preliminary effect sizes that can be used to estimate the sample size required for a full-scale trial. Clinical trial feasibility data will be collected on an ongoing basis throughout the study and clinical data will be collected prior to initiating the intervention (baseline) and at week 8 (response visit) and week 26 (post-intervention visit).

Start date: November 24, 2022
Phase: N/A
Study type: Interventional

The aim of this study is to assess the level of glycemic control and the incidence of surgery-related complications in cardiac patients post-surgery when Continuous Glucose Monitoring (CGM) is utilized, as compared to traditional methods of arterial/venous blood sampling and Point-of-Care Testing (POCT) for glucose monitoring.

NCT ID: NCT06268990 Recruiting - Diabetes Clinical Trials

FMT in Obesity: RYGB vs. LEAN vs. Autologous FMT

DACH
Start date: January 1, 2023
Phase: N/A
Study type: Interventional

This double-blinded proof-of-concept study is proposed to explore the effects of fecal microbiota transfer (FMT) in human subjects. Here we perform FMTs into obese recipients using stool from lean unoperated donors and from previously obese patients after successfull treatment with bariatric Roux-en-Y Gastric Bypass (RYGB) surgery. Obese patients treated with their own material (autologous FMT) serve as controls. After FMT treatment the functional impact of post-surgery microbiome changes on host energy consumption and regulation of blood glucose levels will be analysed. Additionally the variations on the microbiota and metabolite composition will be profiled using extensive sequencing analyses. The major aim of the study is to explore the scientific rationale for targeted gut microbiota modulation in management of obesity and related metabolic diseases.We estimate the transfer of microbiota from RYGB donors is superior to the transfer of lean microbiota at inducing reduced adiposity and improving high blood glucose levels in obese recipients. Each is better than a sham procedure (autologous FMT), which itself can also induce considerable short-term effects.
