Filter by:Hyperglycemia following meals in patients with type 2 diabetes mellitus (T2DM) is a common problem. Recently, our group found that oral consumption of the ketone metabolite, 3-hydroxybutyrate (3-OHB), effectively stimulates insulin secretion and delays gastric emptying.The aim of this study is to investigate the dose/response relationship between 3-OHB servings of 0, 10, 20 and 40 grams 30 minutes before an OGTT and, ii) investigate the role of timing by serving 20 grams of 3-OHB at different timepoints ahead of an OGTT (0, 30 and 60 minutes)
The subject of doctoral dissertation: Assessment of the effects of a meatless, ketogenic restrictive diet on body composition, strength capacity, oxidative stress and immune response During planning of research and topic of the doctoral dissertation, it was considered how to modify a standard ketogenic diet rich in saturated fatty acids so that the use of this model of nutrition has the most anti-inflammatory effect. Therefore, it was decided to conduct a research to check whether a diet rich in omega-3 polyunsaturated fatty acids will show such an effect when following a high-fat diet. Hypotheses: 1. The ketogenic diet reduces systemic inflammation. 2.The ketogenic diet reduces oxidative stress. 3. The ketogenic diet reduces body fat. 4. A ketogenic diet does not worsen strength performance.
What is the effect of a ketone drink on liver glucose production, and postprandial glycemia, in people with type 2 diabetes.
Patients hospitalized in intensive care between January 2014 and December 2023 for ketoacidosis complicated by organ failure in participating departments.
The investigators propose a multicenter prospective study in patients undergoing either an elective bariatric procedure or an elective benign procedure, including laparoscopic/open cholecystectomy, laparoscopic/open hiatus hernia repair, laparoscopic/open inguinal hernia repair, laparoscopic/open umbilical hernia repair or laparoscopic ventral wall hernia repair. Perioperative blood ketone and venous blood gas levels will be measured pre-surgery, post-surgery and on post-operative days until discharge. Our primary research objective is to clarify the expected perioperative ketone and blood gas levels in elective bariatric patients who have been on a VLCD and fasting for surgery, compared to elective surgical patients who have only been fasting prior to surgery.
Assess the acceptability and tolerability of two different commercially available ketone supplements and determine their effects on capillary blood concentrations of the ketone beta-hydroxybutyrate and glucose in young adults.
Randomized, controlled, double-blind, crossover clinical trial, depending on the product consumed, to analyze the efficacy on physical performance of a sports supplement consumed prior to and during competition or training.
The main objective of this clinical trial is to study the effects of orally administered ketone drinks containing the ketone body, 3-hydroxybutyrate (3-OHB), just before a meal in patients with type 2 diabetes. Moreover the investigators will compare the effects of two different ketone drinks. The hypothesis is: 3-OHB as a pre-meal may: - Lower postprandial blood glucose and lipids. - Mediate release of intestinal hormones and affect gastric emptying. - Affect appetite and other subjective measures related to food intake. The effects of 3-OHB as a pre-meal will be investigated by blood samples, isotopic tracers examinations, paracetamol test, questionnaires and meal test.
The objective of this study is to make a comparison between 11C-acetate and 11C-Acetoacetate heart and kidney metabolism
Heart failure (HF) is among the most common causes of death in patients with type 2 diabetes (T2D). Ketones, 3-hydroxybutyrate (3-OHB), have shown to have beneficial hemodynamics effect in patients with hearth failure with reduced ejection fraction. However, this have never been investigated in patients with heart failure with preserved ejection fraction (HFpEF). In this study we would like to investigate the effect of 14 days modulation of circulating ketone body levels on cardiac function and exercise capacity in patients with HFpEF and T2D.
