Active clinical trials for "Diabetes Mellitus, Type 2"

The purpose of this study is to the determine the effect of salt intake and Captopril on the ophthalmic artery (OA) blood supply of individuals with Type 2 Diabetes Mellitus.

White blood cell membrane and surface structures are affected by the metabolic disorders and complications found in diabetes mellitus. Therefore, cellular activation, signal propagation, intracellular signaling as well as bactericidal effector functions are altered. When diabetic symptoms are corrected by the systemic intervention and treatment of the patients (Anti-diabetic Therapy/ADT, i.e. anti-diabetic medication, diet and dietetic supervision, physiotherapy and physical exercises), white blood cell functions will then normalize and reach the functionality comparable to those cells derived from healthy subjects. Gum diseases like periodontitis have long been associated with and termed complications of uncontrolled diabetes mellitus. Vice versa, after diabetic conditions are corrected, periodontitis treatment will be proven effective, when oral hygiene regimen, full mouth decontamination (FD, i.e. the oral use of topical antiseptics prior and after professional mechanical tooth cleaning, tooth as well as root surface planing, polishing as well as gum and soft tissue decontamination in combination with systemic antibiotics) are performed. To reinforce gum healing, reinfection prevention (RP) as well as supportive periodontal therapy (SPT) will be administered by dental professionals on an individual basis and a detailed schedule. If periodontal pockets critical for participant's self care are not eliminated by FD including RP and SPT, and niches >5mm after 6 month persist, patients are informed and offered surgical intervention as indicated for gum disease elimination. Dental follow up exams will be offered to all participants.

Diabetes mellitus is a chronic disease caused by inherited and/or acquired deficiency in production of insulin by the pancreas, or by the ineffectiveness of the insulin produced. It has become a major healthcare problem in India. High-quality, low-cost solutions adapted to the local context are critical to addressing the current crisis in the management of diabetes. Herbal tea consists of tulsi, guava and stevia, which has glucose lowering properties.The aim of this trial is to study the effect of a herbal tea in the glycemic response in the early type 2 diabetes.

Hypoglycemia, frequently asymptomatic, may lead to cardiac arrythmias and induce an increased risk of cardiovascular morbidity and mortality in patients with type 2 diabetes (T2D). The study hypothesize is that the hypoglycemia reduction, achieved with the FREESTYLE LIBRE device, a Glucose Continuous Monitoring system, may decrease cardiac arrythmias associated with hypoglycemia. So the main objective is to evaluate the efficacy of the FREESTYLE LIBRE system, associated with a specific therapeutic education on the cardiac arrythmias reduction, compared to a capillary ASG system with standard therapeutic education, in patient with T2D with high risk of hypoglycemia. This is a open, multicenter, controlled, randomized study in parallel group.

This study will help elucidate the mechanism underlying the cardioprotective and anti-diabetes effect of dietary fiber by exploring a comprehensive set of inflammatory and oxidative stress markers, based on a contemporary understanding of this process. In addition, there have been very few studies that explored the immediate change in oxidative stress and incretin secretion after fiber intake. In this study, the investigators will be able assess the short term metabolic impact of dietary fiber at great details. The result will contribute to dietary recommendation or designing of fiber supplementation for prevention/treatment of diabetes, obesity and cardiovascular disease.

Objectives of the Project The BEYO project is designed based on the middle range theory of self-care of chronic illness and salutogenic theory. The aim of this project is to facilitate self-care behaviours of community-dwelling elderly patients with type 2 diabetes through promoting SOC, and accordingly improve their health outcomes, including promoting quality of life and reducing diabetes-related emotional distress. Content of the Project BEYO is a group-based consultation project. Each group contains 1 facilitator, 1 assistant and 8 elderly patients. 5 weekly sessions are provided to let patients receive health knowledge, discuss problems and experiences, explore available resources and build up goals and solutions. Each session lasts for 40 minutes. Session 1 aims to build social network among group members and introduce group goals and tasks. Session 2-4 covers six topics based on the Chinese guideline for type 2 diabetes released by Chinese diabetes society: (i) healthy dietary, (ii) exercise and activity, (iii) taking medication, (iv) blood glucose monitoring, (v) reducing risks for complication, (vi) healthy coping with mental stress. These middle sessions execute a common session flow to construct an action plan utilizing patients' resources and strengths to achieve the client-centered goal. Session 5 aims to review the process, summarize effective solutions, and set up plans for the future. One-week, one-month and three-month telephone follow-ups are delivered to help patients solve problems encountered during implementing the action plan and evaluate their self-care, SOC and other health outcomes.

In order to evaluate the difference in beta cell mass in morbidly obese patients with type 2 diabetes mellitus (T2D) before and after Roux-en-Y gastric bypass (RYGB), investigators aim to compare quantitative PET imaging of the pancreas in this patient group before and after surgery. Investigators propose to measure the uptake of 68Ga-NODAGA-exendin-4 in the pancreatic beta cells of these patients. Furthermore, investigators aim to compare uptake of the radiolabeled tracer to beta cell function measured by laboratory parameters. These highly relevant data will provide investigators with more information on the contribution of the beta cells to the mechanisms behind resolution of T2D after bariatric surgery and on the prognostic value of pre-operative beta cell mass determination to T2D resolution. This might be of great interest for the assessment of RYGB as an alternative therapy in patients with T2D and a BMI <35, who currently do not meet the international guidelines for bariatric surgery.

This is a randomized controlled trial aimed to determine highly specific personified predictors of response to the therapy by different groups of hypoglycemic drugs (SGLT-2 inhibitors, DPP-4 inhibitors, GLP-1 receptor agonists, sulfonylureas) in patients with type 2 diabetes mellitus, develop an algorithm of personalized therapy based on them, design an organizational and methodological model for prevention of the cardiovascular complications, and create an automated decision-making system for therapy selection to reduce the incidence of cardiovascular events and related adverse outcomes compared to the traditional approach. This is an interventional, randomized controlled trial, open-label study.

In the DEMAND pilot study, we will recruit and randomize 80 participants at two study sites (Umeå and Uppsala) for a one-year intervention. The primary objectives are to study the inclusion rate, the adherence rate, and the acceptability of the intervention. The secondary objectives are to examine the effect of the intervention on intermediate outcomes, including metabolic control (i.e., blood glucose and lipids), body weight, blood pressure, physical fitness, and cognitive function. Third, the investigators will perform focus group interviews to explore the participants views on the intervention to assess the acceptability. The interventions include (a) Mediterranean diet (b) an individualized physical training program and (c) pharmacological treatment for type 2 diabetes (T2D) aimed to achieve individualized optimal goals, according to national guidelines, taking into account the risk of hypoglycaemia. This multi-component intervention is more comprehensive than usual care, and it specifically focuses on vascular domains.

There is currently a critical gap in knowledge of how intestinal bacterial communities alter metabolic substrates available to the host thereby influencing central and enteric nervous system (CNS/ENS) neurotransmitter levels involved in regulating carbohydrate consumption in humans. Understanding these relationships is essential for developing strategies to improve blood glucose control and to reduce the risk of transitioning from prediabetes to type-2 diabetes (T2D). The investigators' long-term goal is to determine the biological underpinnings of behaviors that impact food intake and blood glucose control that contribute to the development of T2D. The objective of this proposal, which is an essential next step in attaining the investigators' long-term goals, is to determine how bacterial populations in the digestive system impact circulating tryptophan (TRP) and large neutral amino acid (LNAA) levels that regulate production of monoamine 5-hydroxytryptamine (5-HT, serotonin) in the ENS and in gastrointestinal system and the brain. The central hypothesis is that a reduced ratio of TRP producing (TRPp) to TRP consuming (TRPc) bacteria (decreased TRPp:TRPc ratio) in the gut will decrease TRP availability following a carbohydrate meal lowering the plasma TRP:LNAA ratio and resulting in less TRP for ENS/CNS production of 5HT. Further, dietary interventions that promote TRPp bacterial abundance within the gut will increase TRP availability to the host. The investigators will test the central hypothesis and, thereby, accomplish the overall objective for this project by pursuing the following specific aims: 1) Assess impact of divergent microbiota on plasma TRP:LNAA ratio in response to acute carbohydrate consumption, and 2) Assess the impact of dietary supplementation with resistant starch (RS) on gut microbiota and circulating TRP:LNAA ratio. During Aim 1, stool samples will be collected from healthy participants. Participants will be stratified based on gut TRPp:TRPc ratio and the response to an acute meal will be assessed by determining plasma TRP:LNAA ratios. During Aim 2 the capacity for 4-weeks of pre-biotic RS (Potato Starch) supplementation to increase the TRPp:TRPc bacterial ratio in the gut will be determined from stool samples. Additionally, plasma TRP:LNAA ratio following acute carbohydrate consumption before and after supplementation will be determined. The scientific contribution will be to determine the impact of RS on TRPp and TRPc bacteria abundance in the gut, and how bacterial populations impact circulating TRP:LNAA levels, that can impact ENS and CNS 5HT production in humans. This contribution will be significant because it will have direct translational implications for human diseases with altered 5HT signaling.
