Mitochondrial Methylation in Type 2 Diabetes
OverweightObesity3 moreThe overarching goal of this proposal is to determine whether DNA methylation of the mitochondrial DNA impairs mitochondrial function in insulin resistant states such as overweight/obesity and type 2 diabetes.
Bariatric Surgery and Male Reproductive Function
ObesityDiabetes Mellitus4 moreObesity is a global public health problem. According to literature reports, as of 2016, China's obese population has reached more than 90 million and type 2 diabetes mellitus has reached more than 100 million, which has brought a serious health and economic burden to China. In addition to various health problems such as cardiovascular, osteoarthritis, and tumors, obesity can also cause abnormalities in reproductive endocrine. In women, it can cause abnormal menstruation, polycystic ovary syndrome, and male obesity can cause secondary gonadal. Hypofunction (MOSH). MOSH is an endocrine dysfunction. It is reported to have a prevalence of approximately 45% in moderate to severe obesity. In addition, studies have pointed out that the prevalence of hypogonadism in men with type 2 diabetes and obesity higher. However, there are no studies on the reproductive function of Chinese male patients after bariatric surgery. Pre- and post-operative semen will be collected for analysis to observe the effect of bariatric surgery on male reproductive function.
The Canadian Diabetes Prevention Program
Diabetes type2According to Diabetes Canada ("DC"), in 2015, the estimated prevalence of prediabetes in Canada (>20 years of age) is 5.7 million people (22.1%). This rate is estimated to increase to 6.4 million people (23.2%) by 2025. Risk factors contributing to prediabetes and consequently Type 2 Diabetes include rising obesity rates, lack of physical activity, an aging population, and the cultural diversity of Canada . There is convincing evidence that modifiable risk factors, such as diet and physical activity reduce the development of Type 2 Diabetes with the benefits extending beyond the active intervention stage. The underlying theory that supports this intervention relates to the imperative need to focus on weight loss and physical activity, with this population that is at risk of developing diabetes, due to its relationship with insulin resistance. DC outlines the importance of intensive and structured lifestyle modification to promote weight loss in order to reduce the progression of prediabetes to diabetes.
N-terminal Pro-B-type Natriuretic Peptide (NT-proBNP) in Type 2 Diabetes Mellitus
Type2diabetesHeart Failure1 moreMore than 400 million people have type 2 diabetes (T2D) globally, and the burden of diabetes-related cardiovascular complications is increasing. Cardiovascular disease (CVD) affects approximately one-third of all individuals with T2D and accounts for half of all deaths in this population despite major advances in the treatment of the disease. Among the different types of CVD, heart failure (HF) is frequently the first CVD manifestation in individuals with T2D. Although the link between T2D and CVD is widely recognised, the absolute risk of cardiovascular events varies among individuals with T2D. As such, effective risk-stratification tool that accurately identify T2D patients at the highest risk of developing incident or recurrent cardiovascular (CV) events is needed. B-type natriuretic peptide (BNP) and its inactive N-terminal precursor NT-proBNP are biomarkers of myocardial stress. They been shown to incrementally improve predictive discrimination of death and CV events in high-risk individuals with T2D. An NT-proBNP-based CVD/HF risk stratification strategy has not been prospectively tested in the multi-ethnic T2D population in Singapore. In this study, we aim to: Evaluate the predictive value of NT-proBNP for death and CV events compared to traditional risk markers [e.g. HbA1c, albuminuria, high sensitivity C-reactive protein (hsCRP), high sensitivity troponin-T (hsTnT)] in a cohort of T2D patients with or without established CVD (defined as ischaemic heart disease, myocardial infarct, unstable angina, prior coronary artery revascularisation, stroke, transient ischaemic attack or PAD) attending a tertiary diabetes care centre. (Patients with history of HF will be excluded.) Compare the performance of NT-proBNP as a single biomarker for CV risk prediction to risk scoring algorithms in T2D patients.
The GATE Trial: Endoscopic Sutured Gastroplasty in Type 2 Diabetic, Obese Patients Using the Endomina...
Diabetes Mellitus Type 2 in ObeseRationale: Diabetes mellitus is a chronic disease that is often associated with long-term macrovascular and microvascular complications and decreased life expectancy. Approximately 70% of patients with type 2 diabetes mellitus (DM2) are overweight or obese. Weight loss benefits several aspects of DM2, such as improved glycemic control, increased insulin sensitivity and reduced fasting insulin. Interventions for weight loss in patients with DM2 include diet, exercise, but also pharmacotherapy and bariatric surgery. Bariatric surgery is indicated at a body mass index (BMI) > 35 kg/m², in combination with other comorbidities. It is associated with better glycemic control and more weight reduction, compared to intensive medical treatment alone. For patients with not adequately controlled DM2 who are not eligible for surgery (i.e., BMI of < 35 kg/m²), there is a therapeutic gap, which could be filled by one of the currently available endoscopic therapies aiming to reduce weight. One of these therapies is endoscopic sutured gastroplasty (ESG), performed with the endomina device (EndoTools Therapeutics S.A.). There is however a paucity of data showing the effect of ESG on metabolic comorbidities including DM2. We hypothesize that ESG with the endomina device will improve glycemic control in patients with DM2 and obesity. Objective: To evaluate the efficacy of ESG with the endomina device on glycemic control, in obese insulin treated type 2 diabetic patients. Study design: This is a prospective, randomized controlled trial. Study population: 58 subjects (29 in each group) with a BMI between 30 and 40 kg/m² and DM2, treated with insulin therapy. Intervention (if applicable): The intervention group will receive ESG performed with the endomina device. The control group will receive standard diabetic care. Main study parameters/endpoints: The primary endpoint is the proportion of patients with a clinically relevant reduction of insulin dose. Secondary endpoints include among others reduction in HbA1c, remission of diabetes, weight loss, quality of life and (serious) adverse events. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: An ESG with the endomina device is known to have only minor adverse events (transient abdominal cramps, nausea, vomiting), and a serious adverse event rate of <1% (no surgical intervention needed, no mortality).
Investigating Plasma Biomarker Molecules Associated With the Progression of Prediabetes to Overt...
Type2 Diabetes MellitusPre DiabetesThere are an estimate 7 million people in the United Kingdom living with pre-diabetes. The increasing number of new cases of pre-diabetes presents a global health concern due to funding implications. The progression from pre-diabetes to overt type 2 diabetes is often characterised by a reduction in insulin secretion (or β-cell dysfunction). Whilst inflammation may contribute to β-cell dysfunction, a complete picture is still lacking. The proposed research will help develop a more complete understanding of the molecules that may trigger β-cell failure, a process that often connects pre-diabetes to overt diabetes. The aims of this project are; Run large-scale proteomics and metabolomics analysis in pre-diabetic individuals to determine possible biomarker molecules. Use measures and / or classifications of insulin resistance and diabetes (i.e. β-cell function and Disposition Index) to establish whether particular metabolic and / or proteomic signatures (aim 1) are associated with the development of pre-diabetes. To determine if the possible metabolite or protein profile changes are associated with the progression or regression of pre-diabetes from baseline (0 month) to the end of the National Diabetes Prevention Programme (NDPP) (9 month).
A Study to Learn More About How Acarbose and Metformin Work When Taken Together and How Safe They...
Type 2 Diabetes MellitusThe study drug, fixed dose combination of acarbose and metformin, have already been approved to take together as a treatment for type 2 diabetes (T2D). Sometimes, researchers continue studying a treatment after it has been approved to learn more about how doctors decide which treatment to give to patients. In this study, the researchers want to learn more about how acarbose and metformin work when taken together and if the patients have any medical problems. The study will include patients with T2D that was diagnosed in the last 3 to 6 months. These patients will also have recently started treatment with acarbose and metformin. The study will include about 2,000 men and women in India who are at least 18 years old. All of the patients will take fixed dose combination of acarbose and metformin tablets based on their doctor's instructions. They will then visit their study site 4 times over 6 months. At these visits, their doctors will ask them questions about how they are feeling and what medications they are taking. If require, the doctors will take blood samples to measure the patients' blood sugar levels as per routine practice. The doctors will also do physical examinations and check the patients' overall health.
Puberty, Diabetes, and the Kidneys, When Eustress Becomes Distress (PANTHER Study)
Type 2 Diabetes MellitusDiabetic Kidney Disease4 moreEarly diabetic kidney disease (DKD) occurs in 50-70% of youth with type 2 diabetes (T2D) and confers high lifetime risk of dialysis and premature death. Youth-onset T2D typically manifests during or shortly after puberty in adolescents with obesity. Epidemiological data implicate puberty as an accelerator of kidney disease in youth with obesity and diabetes and the investigators posit that the link between puberty and T2D-onset may explain the high burden of DKD in youth-onset T2D. A better understanding of the impact of puberty on kidney health is needed to promote preservation of native kidney function, especially in youth with T2D. Puberty is a complex process of physiological changes, including neuroreproductive and growth hormone activation and rapid organ growth, that may predispose organs to injury. The kidneys may be especially susceptible because they are highly metabolically active and second only to the heart with respect to oxygen consumption per tissue mass. During puberty, the kidneys almost double in size, likely increasing the kidneys' already high energy expenditure. In parallel, puberty is associated with physiologic insulin resistance (IR), which is accentuated in obesity. Our central hypothesis is that obese youth with prediabetes and T2D experience relative kidney hypoxia during puberty due to a metabolic mismatch between increased energy expenditure and impaired substrate metabolism. In turn, the kidney hypoxia results in loss of glomerular charge and size selectivity leading to increased transglomerular transport of protein and kidney dysfunction. Our preliminary data showed that pubertal adolescents with obesity and/or diabetes exhibit relative kidney hypoxia compared to normal weight controls using functional magnetic resonance imaging (MRI) and that relative kidney hypoxia is greater in late vs. early puberty. However, determining the pubertal mechanisms contributing to kidney injury in youth with obesity and T2D requires serial evaluations throughout puberty. To assess the impact of pubertal changes within a 5-year study period, the investigators propose an accelerated longitudinal study design in which the investigators will enroll adolescents (8-14 years, 50% girls) with obesity and elevated hemoglobin A1c (HbA1c ≥6%) [n=60], and healthy normal weight controls [n=40] at Tanner (pubertal) stages 1-4 and examine them at baseline, 1 and 2-years. The investigators will then compare data by Tanner stage to construct an integrated portrayal of the physiological changes that occur throughout puberty. Given the rarity of T2D prior to pubertal onset, the investigators chose to enroll a high high-risk group: youth with obesity and HbA1c ≥6.0% to represent youth ranging from those at magnified risk of developing T2D to those recently diagnosed.
Telemedicine Continuous Remote Monitoring of Adults With Uncontrolled Diabetes Mellitus
Diabetes MellitusType 12 moreThe purpose of this single center observational study is to determine the effect of continuous remote continuous glucose monitor (CGM) reporting coupled with a telemedicine intervention (Tele-CGM program) on levels of HbA1C in adults with poorly controlled type 1 or type 2 diabetes. The investigators will follow 200 English and Spanish speaking adults (125 type 2 and 75 type 1 patients) who have an HbA1C >8% over 12 months. The primary analysis will follow the intention-to-treat principle; participants will all be offered the intervention. The primary trial outcome of HbA1c/Glucose Management Indicator (GMI) at 6 and 12 months will be compared from baseline using a linear regression model. The primary independent variable will be the HbA1C from baseline to 6 and 12 months. Patients will serve as their own control. Results will be summarized as group-specific mean, standard deviation (SD) HbA1c, along with a mean treatment difference and 95% confidence interval. Model assumptions including normality and homoscedasticity of residuals will be evaluated; normalizing transformations or rank-based non-parametric procedures will be used as needed. The complete evaluation of HbA1c, including baseline, 6-month and 12 month measurements will be analyzed with mixed effects linear regression, specifying a random participant-level intercept and an unstructured covariance matrix, to accommodate the repeatedly measured data. The secondary trial outcomes of time in range (TIR; CGM glucose levels 70-180) and questionnaires will be compared from baseline to 6 and 12 months using linear regression procedures as detailed above.
