Ketones and Muscle Protein Synthesis

KetosisRegulation of Muscle Protein Synthesis

Ketones are natural substances normally produced by the body during prolonged fasting and starvation, or in response to a "ketogenic" diet to be used as fuel by the brain and muscles. Ketones are therefore similar to dietary proteins, carbohydrates and fats since they represent a source of energy for the body. In addition to serving as a source of energy, ketones have also been shown to stimulate increased rates of muscle protein synthesis in humans. The ingestion of dietary protein is well established to stimulate an increase in the rate of protein synthesis in skeletal muscle. The rate of muscle protein synthesis can be maximized following the intake of 20g of protein. As a result, smaller doses of protein (i.e. 10g) represent a sub-optimal dose of protein because there is still room for improvement concerning muscle protein synthesis. Recently ketone-containing food products have become available that elevate ketone levels in the body without the need for ketogenic diets or prolonged fasting. Therefore, the purpose of this study is to measure skeletal muscle protein synthesis rates after ingesting the following: Ketone monoester Ketone monoester supplemented with sub-optimal dose of whey protein Sub-optimal dose of whey protein It is hypothesized that muscle protein synthesis rates will increase following the ingestion of a ketone-containing beverage. Further, muscle protein synthesis rates will be enhanced when the ketone-containing beverage and sub-optimal protein dose are taken together.

Basal Insulin in the Management of Patients With Diabetic Ketoacidosis (DKA)

Diabetic Ketoacidosis

The study is a multicenter, randomized controlled trial to compare the safety and efficacy of insulin analogs and human insulins both during acute intravenous treatment and during the transition to subcutaneous insulin in patients with diabetic ketoacidosis (DKA).

Cerebral Edema in Pediatric Diabetic Ketoacidosis

Diabetic Ketoacidosis

The purpose of this trial is to compare two different rates of fluid administration during diabetic ketoacidosis (DKA) treatment in children to determine which fluid administration rate is more beneficial for brain metabolism and for preventing or decreasing brain swelling during DKA.

Randomized Control Trial of Fluid Therapy for Pediatric Diabetic Ketoacidosis

Cerebral EdemaDiabetic Ketoacidosis

The investigators will conduct a randomized controlled trial comparing four different intravenous (IV) fluid treatment protocols for pediatric diabetic ketoacidosis (DKA). Two rates of rehydration will be compared; a more rapid rate and a slower rate. Within each of these two basic rehydration protocols, the investigators will vary the type of rehydration fluid used (0.9% saline or 0.45% saline). The investigators will compare the different treatments by conducting assessments of neurological injury, by measuring the frequency of significant cerebral edema, and by measuring long-term neurocognitive function. These studies will allow us to determine whether variations in IV fluid treatment protocols affect acute neurological outcomes of DKA. Additionally, they will provide important data regarding the impact of DKA and DKA treatment on long-term neurocognitive function in children. In this way, the investigators hope to identify a more ideal fluid management strategy for children with DKA. Previous studies have suggested that DKA may cause blood flow to the brain to be reduced and that brain injury might result from this reduction in blood flow and/or the effects of re-establishment of normal blood flow during DKA treatment with insulin and iv fluids. The investigators hypothesize that more rapidly re-establishing normal blood flow to the brain during DKA, by giving fluids more rapidly and using fluids with a higher sodium (salt) content, will help to minimize brain injury caused by DKA.

Modulation of Circulating Levels of the Ketone Body 3-hydroxybutyrate in Patients With Type 2 Diabetes...

Heart Failure With Preserved Ejection FractionDiabetes Mellitus2 more

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.

Use of Blood Ketone Meters to Improve Ambulance Hyperglycaemia Care

Diabetic Ketoacidosis

In this KARMA2 feasibility study the investigators are testing whether ambulance staff can reliably and safely identify patients at high risk of diabetic ketoacidosis using blood ketone meters and start fluid (saline) therapy before arriving at hospital. The investigators aim to include 800 patients in this stepped wedge control study and the results will help decide if a larger study is warranted.

Effects of Ketones and Niacin in Heart Failure Patients

Heart FailureSystolic1 more

Ketones, 3-hydroxybutyrate (3-OHB), have shown to have beneficial hemodynamics effect in patients with hearth failure with reduced ejection fraction. The mechanisms behind these marked hemodynamic effects are currently unknown, but could involve prostaglandin-release. 3-OHB is the endogenous ligand for the G protein-coupled receptor hydroxy-carboxylic acid 2 (HCA2) receptor. This receptor has proven downstream effects on cAMP and systemic effects via release of prostaglandins. In this present study we will investigate the cardiovascular effects of HCA2-receptor stimulation in heart failure patients.

Type 2 DiabetesKetonemia

The use of sodium glucose co-transporter 2 inhibitors (SGLT2i) has been associated with increased serum ketone levels. However, most previous studies included subjects who were either insulin or even drug naïve with relatively short duration of diabetes. It is well known that insulin deficiency increases the risk of developing ketoacidosis with SGLT2 inhibitors. Moreover, since the glucose-lowering effect of SGLT2 inhibitors is at its maximum at 3 to 6 months after use, the extent of increase in serum ketone levels and its clinical relevance with chronic use of SGLT2 inhibitors, especially among insulin-treated patients that often have longer duration of diabetes and potentially more insulin deficient than those who are insulin naive, have not been clearly defined. Therefore, the investigators perform this randomised study to evaluate the effect of SGLT2 inhibitors on serum ketone levels among Chinese patients with T2DM inadequately controlled with insulin therapy.

Two Bag System for Diabetic Ketoacidosis

Diabetic Ketoacidosis

This is a study investigating the best way to treat diabetic ketoacidosis (DKA) with intravenous (IV) fluids in the hospital. The purpose of this study is to determine whether the "two bag" system of administering IV fluids for the treatment of adults with DKA leads to a shorter time requiring intravenous insulin (a shorter time to anion gap closure), when compared to usual care the traditional "one bag" system of IV fluids. Participants will be assigned randomly to either the usual care group or the "two bag" system group. Based on studies performed in the past, the investigators predict that patients treated with the two bag system of IV fluids for DKA will have a significantly shorter time requiring treatment with intravenous insulin when compared to the traditional one bag system.
