Active clinical trials for "Ketosis"

Regional brain glucose hypometabolism occurs during aging and may contribute to the onset of aging-related cognitive impairment in humans. Ketones are the main alternative energy substrate to glucose for the brain. Several studies show that brain ketone uptake and metabolism are unaltered in cognitively-normal older persons and in Alzheimer's disease (AD). Nutritional ketosis is reported to have a positive impact on cognitive performances in mild cognitive impairment and AD. Nevertheless, changes in regional brain glucose and ketone uptake in adults are poorly understood during diet-induced experimental ketosis. The investigators hypothesis was that during diet-induced ketosis, brain ketone uptake would be directly correlated with the elevation of blood ketone levels and inversely correlated to brain glucose uptake.

This study evaluate the metabolic effects of orally ingested ketone bodies. The study is conducted as a randomized, cross over study.

Diabetes negatively affects cognition and increases the risk of developing overt dementia. Decreased cerebral glucose metabolism may be contributing to this effect, thus providing a glucose substitute using ketone bodies might improve neuronal function. In this study the investigators propose to provide quantitative results on cognitive performance during acute hyperketonemia in patients with type 2 diabetes.

This is a phase II trial in individuals who have been diagnosed with type 1 diabetes within the previous 12 months and suffered from diabetic ketoacidosis at onset of disease. The purpose of this study is to determine whether allogeneic umbilical cord mesenchymal stem cell transplantation is effective in the treatment of patients with severe type 1 diabetes.

Chronic, ambulatory heart failure patients will be given ketone ester dietary supplementation to determine therapeutic efficacy, metabolic adaptation, pharmacokinetics, associated cognitive changes, and safety within this patient cohort in order to establish preliminary data to later conduct a multi-center randomized clinical trial.

The purpose of this study is to assess if an enteral ketogenic feed will cause a ketotic state in critically ill patients on intensive care.

The goal of the study is to see if the addition of a carbohydrate- and protein-enhanced gel during labor speeds labor and reduces the rate of cesarean delivery.

The purpose of this study is to determine if a 6-week period of ketone salt supplementation affects physiological, emotional, cognitive, and/or behavioral health markers in individuals with PTSD.

Empagliflozin (Jardiance), a highly potent and selective inhibitor of the sodium-glucose cotransporter 2 (SGLT2), was approved in Europe in May 2014 for the treatment of type 2 diabetes mellitus (T2DM) to improve glycaemic control in adults. As part of the risk management plan, Boehringer Ingelheim International GmbH (BI) has committed to conduct a post-authorisation safety study (PASS) to evaluate the liver and renal safety of empagliflozin. The study will also evaluate the risks of severe complications of urinary tract infections (UTIs) and genital infections. To evaluate the association between empagliflozin use and mentioned outcomes routinely collected health information from the Clinical Practice Research Datalink (CPRD), the Hospital Episodes Statistics, and Office of National Statistic will be used. This PASS will be conducted through an observational cohort study among adult patients with T2DM and at least 12 months of continuous enrolment in the CPRD where new users of empagliflozin will be compared to new users of dipeptidyl peptidase-4 (DPP4) inhibitors. Estimations will be made on the crude and adjusted incidence rates and adjusted incidence rate ratios of the primary and secondary outcomes.

An open-labeled intervention study testing healthy, lean, and male volunteers on two separate occasions: blood sampling after consuming 36 gram 3-Hydroxybutyrate (3-OHB) salt. blood sampling while given a variable rate of 3-OHB salt intravenously to replicate the concentrations seen during oral consumption. The primary outcome is differences in insulin concentrations (incremental AUC) 180 minutes after 3-OHB consumed orally vs. intravenously. Secondary outcomes includes iAUC for other gastrointestinal hormones and substrates (Glucagon, GLP-1, GIP, glucose, and 3-OHB) Gastric emptying will be evaluated using 1500 mg Paracetamol consumption before each intervention day. Urine will be analyzed for ketone concentrations/excretion rates.
