NCT ID: NCT04089332 Completed - Insulin Resistance Clinical Trials

Insulin Resistance in Adolescents

Start date: October 4, 2019
Phase: N/A
Study type: Interventional

The growing population of adolescents with insulin resistance (IR) is predicted to create a large public health burden in the next few decades. This study examines the function of brain blood vessels and cognitive function, to test if increasing severity of IR in adolescents is related to reduced cognitive function and reduced brain blood vessel function. Findings from this study may help create treatments to delay or prevent some of the negative effects of IR on cognitive and vascular health.

The goal of this protocol is to evaluate the effect of addhing linagliptin to patients with prediabetes who do not reverse to normoglycemia after 12 months of treatment with metformin alone. The duration of the study will be 6 months, and it is primarily a efficacy study. Main outcomes will be glucose levels during OGTT, insulin secretion and pancreatic beta cell function measured by the disposition index derived from the OGTT.

NCT ID: NCT04074668 Completed - Diabetes Clinical Trials

Control of Renal Oxygen Consumption, Mitochondrial Dysfunction, and Insulin Resistance

CROCODILE
Start date: January 1, 2020
Phase:
Study type: Observational

Type 1 diabetes (T1D) is a complex metabolic disorder with many pathophysiological disturbances including insulin resistance (IR) and mitochondrial dysfunction which are causally related to the development of diabetic kidney disease (DKD) and which contribute to reduced life expectancy. Renal hypoxia, stemming from a potential metabolic mismatch between increased renal energy expenditure and impaired substrate utilization, is increasingly proposed as a unifying early pathway in the development of DKD. By examining the interplay between factors responsible for increased renal adenosine triphosphate (ATP) consumption and decreased ATP generation in young adults with and without T1D, this study hopes to identify novel therapeutic targets to impede the development of DKD in future trials. The investigators propose to address the specific aims in a cross-sectional study with 30 adults with T1D and 20 controls without a diagnosis of diabetes. For this protocol, participants will complete a one day study visit at Children's Hospital Colorado. Patients will undergo a Dual-energy X-Ray Absorptiometry (DXA) scan to assess body composition, renal Magnetic Resonance Imaging (MRI) to quantify renal oxygenation and perfusion, and a Positron Emission Tomography/Computed Tomography (PET/CT) scan to quantify renal O2 consumption. After the PET and MRI, participants will undergo a hyperinsulinemic-euglycemic clamp to quantify insulin sensitivity. Glomerular Filtration Rate (GFR) and Effective Renal Plasma Flow (ERPF) will be measured by iohexol and PAH clearances during the hyperinsulinemic-euglycemic clamp. To further investigate the mechanisms of renal damage in T1D, two optional procedures are included in the study: 1) kidney biopsy procedure and 2) induction of induced pluripotent stem cells (iPSCs) to assess morphometrics and genetic expression of renal tissue.

NCT ID: NCT04048642 Completed - Obesity Clinical Trials

Effects of a Plant-Based Diet on Insulin Requirements and Obesity Markers in Obese Adults With T2DM

Start date: December 1, 2020
Phase: N/A
Study type: Interventional

This is a crossover study utilizing a Dietary Approaches to Stop Hypertension (DASH) diet and a whole-food, plant-based diet among subjects with type 2 diabetes who require insulin. Outcomes are short-term changes in insulin requirements and changes in various biomarkers.

NCT ID: NCT04046289 Completed - Obesity Clinical Trials

Effects of Probiotics and Calcium Supplementation on Growth, Development, and Metabolic Parameters

PROBIOCAL
Start date: January 26, 2019
Phase:
Study type: Observational

Stunting is still a major problem in developing countries, including Indonesia, and has been associated with impaired development. Stunted children have also a higher risk of metabolic syndrome in adulthood. The gut microbiota, as a part of intestinal integrity, may promote intake of nutrient during childhood. Probiotics supplementation may optimize the balance of gut microbiota and further improve child growth during the window period. Furthermore, calcium could also improve child growth by increasing the resistance to intestinal infection. However, the long-term effects of gut microbiota optimization during childhood using probiotics and calcium on growth, development, and the metabolic condition has not widely studied.

NCT ID: NCT04041492 Completed - Clinical trials for Diabetes Mellitus, Type 2

Effect of Vitamins D3 and K2 in uOc and Insulin Serum Levels in Patients With Diabetes Mellitus

Start date: February 14, 2017
Phase: N/A
Study type: Interventional

Introduction: Patients with DM2 have chronic hyperglycemia derived from a decrease in insulin sensitivity, cause of comorbidities such as bone demineralization, decreasing quality of life and increasing mortality. This could be related to changes in the serum levels of carboxylated Osteocalcin and Insulin, together with the deficit the daily consumption of vitamins D3 and K, which is crucial for the process of mineralization of the bone matrix. Research question: What is the effect of supplementation with Vitamins D3 and K2 on serum levels of Carboxylated Osteocalcin and Insulin in patients with Type 2 Diabetes mellitus? Hypothesis: Supplementation with Vitamins D3 and K2 modifies the serum levels of Carboxylated Osteocalcin and Insulin in patients with Type 2 Diabetes mellitus. General Objectives: To assess the effect of supplementation with Vitamins D3 and K2 on serum levels of Carboxylated and Non-Carboxylated Osteocalcin in patients with Type 2 Diabetes mellitus. Material and Methods: Clinical trial, double blind, randomization, 40 patients with DM2, 35-65 years, supplementation (3 months), clinical and laboratory determinations (uOC and Insulin). - Group 1: Vitamin D3 1000UI + Placebo - Group 2: Vitamin K2 100 mcg + Placebo - Group 3 (Positive Control): Vitamins D3 1000UI + K2 100 mcg

NCT ID: NCT04016337 Completed - Obesity Clinical Trials

Evaluation of New Beverages Rich in Bioactive Compounds for the Modulation of Energetic Metabolism in Overweight Adults

BEBESANO
Start date: September 1, 2017
Phase: N/A
Study type: Interventional

During last decades, an excessive intake of sugars has been observed in westernized countries, mainly due to the consumption of sugar-rich soft drinks. Epidemiological studies have pointed out a positive correlation between the consumption of such drinks and the risk of obesity, diabetes, and cardiovascular diseases. Therefore, there is a growing trend looking for new non-caloric alternatives (sweeteners) in order to reduce the sugar content of foodstuffs without losing their sweetness and tastefulness. However, some questions regarding sweeteners have recently arisen as their effects after long-term consumption have not been fully unravelled. They could also contribute to a higher caloric intake and to disrupt the gut microbiota. Besides seeking new alternatives for the high intake of sugar-rich drinks, there is a need for increasing the consumption of fruits and vegetables among general public. Developing new products to stretch the shelf-life of fresh fruits, preserving their nutrients, and reducing the energetic content of fruit juices should also be accomplished. In this sense, lemon juice has been proposed as an interesting ingredient in the elaboration of soft drinks due to its distinctive aroma and high nutritive value. Its combination with maqui berry juices contributes to stabilize the colour and phenolic compounds that both products contain (mainly flavanones for lemon juice and anthocyanins for maqui). The beneficial effects of these vegetal foodstuffs and their phenolic substances on glucose intolerance have been reported.The aim of BEBESANO is studying the beneficial effects of sugar-free, rich-in-phytochemicals drink consumption on postprandial hyperglycaemia, in order to provide alternatives to excessive sugar intake and counteract the postprandial response linked to sugar consumption in subjects with low levels of chronic inflammation such as overweight people. Moreover, BEBESANO will shed light on the interactions of food constituents with the main pathways involved in the lipid and glucose metabolism, oxidative stress, inflammation, and hormonal regulation in overweight population.

NCT ID: NCT04014686 Completed - Hypertension Clinical Trials

12 Weeks of Resistance Band Exercise Impacts on Metabolic Syndrome Progression in Postmenopausal Women

Start date: April 1, 2018
Phase: N/A
Study type: Interventional

The purpose of this study was to examine the impacts of a 12-week resistance band exercise program on insulin resistance, blood lipid profiles, body composition, and blood pressure in postmenopausal women with obesity. Thirty-six postmenopausal women participated in this study. Participants were randomly allocated into the resistance band training group (EX, n = 18) or the control group (CON, n = 18). The EX group performed a resistance band exercise training program 60 minutes per day, 3 times per week, for 12 weeks. The CON group did not participate in any exercise, dietary, or behavioral intervention. Blood glucose, insulin, homeostatic model of insulin resistance (HOMA-IR), blood lipids, blood pressure, and body composition were measured before and after 12 weeks of EX or CON.

NCT ID: NCT04010370 Completed - Healthy Lifestyle Clinical Trials

Correlation of Several Formulas to Evaluate Insulin Sensitivity With the Predicted M Index

Start date: February 1, 2019
Phase:
Study type: Observational

Recently, an index based on the oral insulin sensitivity index with glucose (OGIS) has been proposed in combination with anthropometric variables, called PREDIcted M (PREDIM), however, there is no evidence of the correlation of this with respect to the various indices (McAuley, Belfiore, Cederholm, Avignon, Matsuda, Gutt, Stumvoll, HOMA-IR (Homeostatic Model Assessment for Insulin Resistance), ISI (Insulin Sensitivity Index), Raynaud, QUICKI (The quantitative insulin sensitivity check index), FIRI (Fasting Insulin Resistance Index), Bennett, TyG (triglycerides and glucose index)) in healthy patients.
