Clinical Evaluation of the Effect of Duodenal-Jejunal Bypass on Type 2 Diabetes
Type II DiabetesThe aim of this study and the primary outcome is to clinically evaluate effect of laparoscopic duodenal-jejunal bypass on non-obese type 2 diabetes. Secondary outcomes will evaluate CCK, FFA, Cholesterol Ghrelin, C-peptide, and HbA1c levels. Patients will be followed closely to ensure the desired results are sustained in long term
Immune Profile and Complication Risk in Type 2 Diabetes
Diabetes MellitusType 2The aim of this study is to investigate the relation between individual differences in pattern recognition molecules (PRM's) in the innate immune system and the prevalence and development of vascular complications in patients with type 2 diabetes. This is based on the hypothesis that pattern recognition molecules (PRM's) in the innate immune system contributes to a chronic low grade inflammation in diabetic patients. Variation in PRM's - at the genome, proteome as well as the functional level - are therefore associated with the degree of chronic low grade inflammation, and probably also with the prevalence of vascular complications.
Effect of Incretin-related Drugs on Dietary Intake in Japanese Patients With Type 2 Diabetes Mellitus...
Type 2 Diabetes MellitusIt is well known that incretin, particular GLP-1enhances satiety and reduces energy intake in controlling appetite and dietary in humans (Flint A, et al. Gutzwiller JP et al.). Recently, incretin-based therapy has been attracted a lot of interest (Hare KJ, Knop FK). However, it is not clear how the incretin-based therapy affects energy and content of dietary intake in patients with type 2 diabetes mellitus (T2DM). Previously, the investigators reported the amount of energy and content of dietary intake in type 2 diabetic Japanese patients with more than 10 years of long time duration after discovery using questionnaire (Inoue K et al.) and the patients were impaired a secretion of active GLP-1 (Kamoi et al). The investigators examine whether the incretin-based therapy effects on the energy and content of dietary intake in the same patients before and one year after administration of incretin-related drugs using the same method previously (Inoue K et al.).
Effectiveness of Sitagliptin in Glycemic Control in Real World
Type 2 Diabetes MellitusThis study will evaluate whether the addition of sitagliptin treatment provides additional decrease in HbA1C levels and increase in goal attainment in patients with inadequate glycemic control on their current oral anti-glycemic therapy in real world practice.
Visualizing Beta Cells After Bariatric Surgery
Type 2 Diabetes MellitusIn order to evaluate the difference in beta cell mass in patients with and without complete resolution of type 2 diabetes mellitus (T2DM) after Roux en Y gastric bypass (RYGB) investigators aim to compare quantitative PET imaging of the pancreas between these patient groups. These highly relevant data will provide investigators with more information on the possible role of beta cell mass in the mechanisms behind resolution of T2DM after bariatric surgery. This would be of great interest for the assessment of RYGB as an alternative therapy in patients with T2DM with a BMI <35, who currently do not meet the international guidelines for bariatric surgery.
Gene Expression Profiling and Bioinformatic Analysis Identifying Genes and Biochemical Pathways...
Type 2 DiabetesType 2 diabetes is a disorder of the metabolic system that greatly affects individual health and imposes significant cost for society on health care. It is necessary to initiate research with emphasis on improvement on quality of life and reduce the serious complications as a result of type 2 diabetes. In type 2 diabetes insulin resistance and impairment of insulin secretion by beta-cells are the major pathophysiological defects and characterized by raised plasma glucose levels. Today, little is known about gene regulation and biochemical pathways involved in the disease. Bioinformatics and gene expression microarrays (GEM) will be applied to gain insight into the molecular pathophysiology of type 2 diabetes. The simultaneous monitoring of thousands of genes in parallel can identify novel genes and entire biochemical pathways that are dysregulated at the transcriptional level. Affymetrix Inc. chips or spotted arrays will be applied as DNA microarray tools. Bioinformatic software programs and databases will be employed as data mining tools in order to perform statistical analysis, cluster analysis and biochemical pathway analysis. Biopsies from skeletal muscle and adipose tissue from both diabetics and nondiabetics will be applied. Changes in genes and biochemical pathways between diabetics and nondiabetics and functional relationships between adipose tissue and skeletal muscle will be investigated. Grouping of subtypes in type 2 diabetes will be performed and a classification system will be constructed. Building a classifier may provide better and more precise diagnosis of type 2 diabetes. Major advances in health science of type 2 diabetes thus seems to be promising and paving the way for individual treatment based on a more precise diagnosis.
Medication Use Among American Indians Adults
Type 2 DiabetesMedication AdherenceThe goal of this study is to explore facilitators of and barriers to medication adherence within the context of local social determinants of health (SDOH) that are not available in the EHR. for American Indians with type 2 diabetes. The main aim is: Identify facilitators of and barriers to medication adherence within the context of SDOH, Electronic Health Record (EHR) derived medication adherence [HbA1c < 7 (at target); HbA1c >7% to ≤9% (above target); and HbA1c > 9% (uncontrolled)].
A Study of Glucose Control in Participants With Type 1 and Type 2 Diabetes
Type 1 DiabetesType 2 DiabetesThe main purpose of this study is to determine whether combining meal, glucose and insulin data in a web-based system will improve management of type 1 (T1D) and type 2 diabetes (T2D). No study drug will be given. The study will last about 18 weeks.
Changes in Incretins Response and Glycemic Control After Gastric Bypass Surgery in Type 2 Diabetic...
Type 2 DiabetesObesityThe purpose of this study is to determine the early changes in gut hormonal, and other metabolites with known relations to the glycemic homeostasis. The study mainly focus on these responses to food in the diabetic patient, compared to the non-diabetic, after gastric bypass surgery. Also aiming for recording changes in the earliest postoperative phase.
Regional Fatty Acid Metabolism in Humans
Diabetes MellitusType 2There are several studies looking at how dietary fat is metabolized by humans. We give special meals and collect blood, breath, urine and fat samples to study how people burn and store dietary fat.
