Filter by: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.
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.
When linking dietary interventions and blood glucose management, much of the existing research - particularly studies exploring the effects of vinegar - has relied on discrete readings from the conventional testing methods: blood samples or glucometers. These methods lack the capacity to provide insights into blood glucose dynamics 24/7. Recognizing this gap, the current study aims to utilize continuous glucose monitoring to examine the impact of daily vinegar ingestion on glucose variability in adults identified as glucose intolerant.
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.
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.
The aim of this research is to evaluate the safety and efficacy of green tea in obese pediatrics with prediabetes versus the metformin therapy alone that is given to these patients. The primary outcome is to tackle the insulin resistance in these patients to prevent the deterioration of prediabetes to type 2 diabetes. The assessment of the effect on insulin resistance by using homeostatic model assessment for insulin resistance (HOMA-IR levels) as well as the effect on blood glucose levels and glycated hemoglobin. The other primary outcome is to observe the effect of the intervention on the lipid profile, leptin and adiponectin. The secondary outcome is to determine the effect of green tea on the oxidative and inflammatory markers and to evaluate its safety and efficacy. The study design is prospective parallel randomized open- label controlled interventional clinical trial that will be conducted in El-Demerdash hospital children's endocrinology unit. The patients who fit the inclusion criteria will be educated about the study protocol and will be required to sign a written informed consent. The inclusion criteria are: children whose age is between 10 to 18, whose HOMA-IR >2.5, BMI >= 95th percentile and have no sensitivity towards green tea and willing to sign informed consent. Patients who have causes of endogenous obesity will be excluded and those who have any other comorbid conditions. All patients fulfilling the inclusion criteria will be randomly assigned by simple randomization into either Group 1 (Control group): Consists of 45 patients who will receive their conventional therapy which is Metformin 500 mg film coated tablets (Glucophage). Group 2 (Interventional group): Consists of 45 patients who will receive Green Tea 300 mg (Green tea 300 mg film coated tablets Mepaco Egypt) thrice daily + Metformin 500 mg film coated tablets (Glucophage). At baseline the following parameters will be collected during patients' interview and from patients' files: Demographic data as age, sex, weight and height (BMI), family history, medical history, medication history. Thyroid functions (TSH/T3): to rule out any other endocrine causes of obesity. Cortisol levels (am and pm): to rule out any other endocrine causes of obesity. The following laboratory' measurements will be tested at baseline and at the end of study (4 months): Complete Blood Picture, fasting blood glucose and postprandial blood glucose, fasting plasma insulin, homeostatic model assessment for insulin resistance, homeostatic model assessment for β-cell function, lipid profile, leptin, adiponectin, malondialdehyde, liver functions, kidney functions, c-reactive protein, nuclear factor kappa beta. Patients will be educated about the side effects and/or adverse effects of green tea, where safety and tolerability will be monitored by reporting the incidence of any side effect and /or adverse effect such as liver problems, yellowing of the color of skin or white of the eyes or stomach pain. Participants will be followed up during the study period every 2 weeks through clinic visits and by phone in order to assure compliance as well as monitoring of incidence of any side/adverse effects and informing the patients who to handle it.
The goal of this clinical trial is to compare the degree of effort during a resistance exercise session on blood glucose levels in individuals with prediabetes or type 2 diabetes mellitus. The main questions it aims to answer are: - Do individuals with prediabetes or type 2 diabetes mellitus need to perform resistance exercise with a high degree of effort for their blood glucose to improve? - How do they feel (their enjoyment, discomfort) after the sessions with different degrees of effort? Participants will perform 3 situations separated by at least 4 days, after being familiarized with all exercises and procedures: - One control day, when they will not exercise; - A high-effort resistance exercise session; - A low-effort resistance exercise session Researchers will measure blood glucose levels and psychological responses after these situations to see if the effort was important for the improvement of their blood glucose and how effort affected the way they felt after each situation.

The main goals and questions it aims to answer are: - Acceptability WB-EMS training in sedentary adults with pre-diabetes, - Has WB-EMS training positive effects on HbA1c and other biomarkers? Researchers will compare the intervention group with two control groups to see if WB-EMS training has effects on pre-diabetes.
The aim of this study is to determine if completion of the Diabetes Prevention Program (DPP) via the Transform 10 website can significantly decrease hemoglobin A1c (HbA1c) levels and Body Mass Index (BMI) in prediabetic individuals undergoing total hip arthroplasty (THA) procedure. As part of the standard procedure of the Centers for Disease Control (CDC)-approved DPP program, all study participants will report their active minutes and weight via the Transform10 website throughout the 6 month-long program. In addition, participants will have a repeat Hba1c test ordered at the end of the program by the medical director as part of routine procedures. The main questions it aims to answer are: 1. Is an augmented digital diabetes prevention program an effective strategy for weight loss in adults with prediabetes undergoing elective total hip arthroplasty? 2. Is an augmented digital diabetes prevention program an effective strategy to decrease HbA1c in adults with prediabetes undergoing elective total hip arthroplasty? 3. Is an augmented digital diabetes prevention program an effective strategy to improve postoperative outcomes and patient satisfaction in adults with prediabetes undergoing elective total hip arthroplasty? Participants will be randomized to get the DPP on their day of surgery (intervention group) or get their DPP 6 months after their day of surgery (control group). Comparing the intervention group to the control group, the researcher's primary outcome is change in percent of body weight before and after a 6-month intervention period.
