Active clinical trials for "Diabetes Mellitus"

This project will assess the independent predictors of impaired muscle and bone strength through a longitudinal observation of a cohort of subjects with type 1 and 2 diabetes consecutively attending an outpatients diabetes clinics for the annual screening of complications.

The aim of this study is to clarify whether lifestyle intervention provided to people with high type 2 diabetes risk will lower the cumulative incidence of diabetes. Furthermore, the aim is to study the effect of lifestyle intervention on cardiovascular risk.

The Diabetes Prevention Program (DPP) was a multi-center trial examining the ability of an intensive lifestyle or metformin to prevent or delay the development of diabetes in a high risk population due to the presence of impaired glucose tolerance (IGT, 2 hour glucose of 140-199 mg/dl). The DPP has ended early demonstrating that lifestyle reduced diabetes onset by 58% and metformin reduced diabetes onset by 31%. DPPOS (2002-2013) is designed to take advantage of the scientifically and clinically valuable DPP participants. This group of participants is nearly 50% minority and represents the largest at risk population ever studied. Clinically important research questions remain that focus on 1) durability of the prior DPP intervention, 2) determination of the clinical course of precisely known new onset diabetes, in particular regarding microvascular disease, CVD risk factors and atherosclerosis, 3) close examination of these topics in men vs women and in minority populations. The major aims of DPPOS-3 (2014-2025) take advantage of the long-term randomized exposure of the study cohort to metformin and the aging of the DPPOS cohort. The metformin exposure and high degree of study retention and adherence (~85% of the DPPOS cohort continues to attend annual and mid-year visits) allows DPPOS-3 to examine the long-term effects of metformin on cardiovascular disease (CVD) and cancer outcomes, outcomes of great clinical interest and import.

It is unknown if obesity contributes to the development of heart disease in African American men and women. This study was created to determine whether there is a relationship between sex and body size and the incidence of heart disease in African American men and women. Researchers will attempt to associate obesity with the presence of heart disease risk factors. Risk factors that will be studied include; total body fat, body fat distribution, fat content of the blood (triglyceride concentration, low density lipoproteins [LDL], and high density lipoproteins [HDL]), how fast fat is removed from the blood, and how well insulin works in the body. Scientific studies have shown that obesity and increased levels of fat content in the blood are important risk factors for heart disease in Caucasian women. However, similar studies in African American women have failed to show the same correlation. In fact, it appears that African American women in all three body weight groupings, nonobese, overweight, and obese experience high death rates due to heart disease. In addition, prior research has shown that obese African American men tend to have elevated levels of fat in the blood while African American women have normal blood fat levels. Therefore, if high levels of triglycerides (fat found in the blood) are not seen in non-diabetic obese African American women, it cannot be considered a risk factor in this population. This suggests that studies conducted on Caucasian women may not provide insight into heart disease risk factors in African American women. The study will take 2000 healthy non-diabetic African American men and women (ages 18-70) and body mass index 3 subgroups; nonobese, overweight and obese. Diabetes undeniably increases the risk of heart disease. Therefore patients suffering from diabetes will not be included in the study. Candidates for the study will undergo a series of tests and examinations over 2 outpatient visits. Subjects will have body fat analyses, resting energy expenditure measurements, an EKG (electrocardiogram), and specific blood tests. Researchers believe this study will provide significant insight into the causes of obesity and heart disease in African Americans.

This clinical research studies the physiology and immunology of new-onset post-transplant diabetes mellitus in patients undergoing allogeneic stem cell transplantation. Oral glucose tolerance tests (OGTT), hyperglycemic clamps, and immune assays will be used to define the mechanisms associated with abnormal glucose homeostasis following stem cell transplantation. Information from this clinical trial could be used to develop standardized screening procedures or to develop optimal treatment strategies for patients developing post-transplant diabetes mellitus.

The prospective observational study entitled "Heidelberg Study on Diabetes and Complications" is designed to Monitor the presence and development of diabetic complications in type 1 and type 2 diabetic patients, as well as pre-diabetics. Mail Goal is to detect new metabolic mechanisms or new risk factors for the development of diabetic complications in order to identify risk-subgroups. Non-diabetic controls will be enrolled for reference and comparison.

The Pre-DICTED (Pre-Diabetes Intervention and Continued Tracking to Ease-out Diabetes) program is a community-based diabetes prevention program. This study aims to test the effectiveness of structured, group-based lifestyle interventions with stepwise addition of metformin, if required, among subjects with pre-diabetes in multi-ethnic Singapore.

The main purpose of the present study is to perform a 10 weeks dietary intervention study with a follow-up for 52 weeks in children from 7-14 years of age with overweight or obesity. In a caloric restricted and increased physical activity setting the control group will consume a low-moderate protein (15E%/day) diet whereas the intervention group will consume a higher protein (25E%/day) diet. Furthermore, the investigators want to investigate the effect of frequent follow-up after intervention. Compared to the low-moderate protein diet, the investigators hypothesis that a diet with higher consumption of protein-containing foods will more effectively induce weight loss (a reduction in BMI-SDS) or weight maintenance in children with overweight or obesity, and improve risk factors for type 2 diabetes and Quality of Life.

The aim of this study is to utilise ultrasound, using an established method for detecting NAFLD, to determine whether the presence of NAFLD in women with GDM, detected during routine scanning, is a marker of deterioration in glycaemic status post-partum. We propose to assess the relationship between NAFLD and surrogates for insulin resistance as well as glycaemic status, insulin sensitivity and β-cell function, after delivery. The study is not seeking to compare the incidence of T2DM between those with and without NAFLD. This would require a longer follow-up and larger cohort size. Instead, it aims to quantify the degree of early deterioration of glycaemic status in these groups using insulin resistance markers. This is a clinically important issue as a greater level of insulin resistance would in itself trigger clinical intervention, including vigilant follow-up and empowerment for proactive healthy life style changes, which have been shown to prevent diabetes development .

INTRODUCTION AND AIM Diabetes Mellitus (DM) is a common endocrine disease in the world. Colon polyps and colorectal cancers are reported more in DM patients. Therefore diabetic patients are recommended to have colonoscopy frequently. The aim of this study is to search the effect of DM on hemodynamics, procedure times, anesthetic consumption and complications in colonoscopy under sedoanalgesia. MATERIALS AND METHODS Following Institutional Review Board and Ethics Committee approval of Başkent University, this study is planned to be prospective and double-blind in 50 type II diabetic and 50 non-diabetic ASA I-II, aged between 18-65 years female patients scheduled for elective colonoscopy under sedoanalgesia. Exclusion criteria are age outside the range of 18-65 years, ASA phsical status ≥ 3, inability to provide informed consent, pregnancy, previous adverse reactions to medications used in the study, history of anesthesia and sedation in the last 7 days, psychiatric or emotional disorders, addiction to the opioids or sedatives used in the study, diabetic nephrophathy, high BUN and creatinine values, advanced stages of diabetic nonalcoholic liver disease and high liver function tests, diabetic sensorymotor and autonomic neuropathy. After sedoanalgesia is applied systolic and diastolic blood pressure, heart rate, SpO2, respiratory rate, RSS, MPADS, procedure times, total anesthetic doses, stomach ache and other effects will be recorded. EXPECTATIONS AND SCIENTIFIC CONTRIBUTIONS There is evidence about determining the risks that diabetic patients have during colonoscopy and applying a special patient care protocol for these patients is suggested to improve the procedure and outcomes.
