Filter by:The safety and efficacy of basal insulin during intravenous insulin infusion for hyperglycemic crisis patients under critical care is still unknown. We assumed that concurrent basal insulin subcutaneous injection and intravenous insulin infusion for critically ill DKA and HHS patients would shorten the time of hyperglycemic crisis correction and achieved better glycemic control(decrease hypoglycemia and rebound hyperglycemia).
There have been concerning case reports of marked elevations of LDL-c in some individuals consuming a KD and Dr. Lewis has been referred a number of these cases to his lipid clinic, some of whom have had extreme elevations of LDL that mimic familial hypercholesterolemia. These marked elevations of LDLc are unique to a ketogenic diet and far exceed the typical mild elevations seen in those consuming a high fat, low carbohydrate LGIT. The degree of elevation of LDL-c suggests that ketosis per se may impair LDL receptor-mediated LDL particle clearance. This clinical observation is a concerning and clinically important issue since millions of people are consuming this popular diet. There are currently no studies that have examined the mechanism of the LDL-raising effect of a ketogenic diet.
This randomized controlled trial will evaluate the effect of a ketogenic diet and/or exogenous administration of ketone bodies vs conventional diet on the ejection fraction of patients with non-ischemic chronic heart failure, measuring MRI biomarkers.
This study will evaluate whether supplementation of exogenous ketones in patients with severe left ventricular dysfunction and acutely decompensated heart failure requiring inotropic therapy would improve the patient's hemodynamics and symptoms.
We aim to investigate the hemodynamic effects of weight-adjusted dosing of ketone monoester en patients with chronic heart failure.
The purpose of this study is to test different methods of preparation that can be used prior to a test called an FDG PET/CT scan. FDG PET/CT scans are routinely done for evaluation of heart inflammation. Standard preparation for the scan includes a ketogenic (high fat and low carbohydrate) diet for 24 hours and overnight fasting to help suppress the amount of sugar taken up in the heart muscle. However, Investigator still do not know if this preparation is the most effective method. So the Investigator, want to investigate alternative methods for decreasing the amount of sugar uptake seen in the heart during FDG PET/CT scan, thus, investigator will have participants try up to 3 different methods of preparation prior to the FDG PET/CT scans to see which type of preparation works the best.
The scientific goal of this study is to examine the effects of a ketogenic diet on hypoglycemia tolerance and brain function in people with type 1 diabetes mellitus (T1D) and to clarify the mechanistic role of ketones in this process. Glycemic management of T1D is typified by alternating periods of hyper- and hypo-glycemia. Because brain metabolism under usual conditions depends on glucose, acute hypoglycemia leads to immediate complications including impaired cognitive function and a counter-regulatory hormone response. Recurrent hypoglycemia is associated with functional and structural changes in the brain and contributes to the cognitive decline observed in individuals with diabetes. The state of nutritional ketosis (as it occurs during fasting or when following a ketogenic [very low carbohydrate] diet) may protect against these acute and chronic complications. As the body relies on fat metabolism, ketone bodies build up and provide an alternative fuel for the brain. Studies during hypoglycemia have shown better cognitive function and less hypoglycemia symptoms in the setting of nutritional ketosis or with ketone administration. This physiological benefit may have special relevance for people with T1D who experience hypoglycemia frequently. To date, no mechanistic studies have examined brain effects of nutritional ketosis in T1D; nor have any trials explored the potential relevance of this for diabetes care.
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.
20 healthy trained males will volunteer to participate in this study. there will be 2 treatments: Carbohydrate- ketone supplementation and carbohydrate alone. The purpose of this study is to evaluate the effect of glucose-ketone supplementation on a 20 km cycling time trial with a 2-hour feeding during a 4-hour recovery period following glycogen depleting exercise.
20 healthy recreationally active men and woman aged 18-35 will participate in the study. There will be three treatments involved: Caffeinated ketone supplements, non-caffeinated ketone supplement and water-placebo. Participants will complete the protocol three times and the treatment order will be systematically rotated to avoid any order effect. The three main trials will be separated by at least 1 week. After providing the corresponding treatment, participants will be given 30 minutes and after, they will perform a standardized 10-minute warm-up, followed by the 20 km time trial and a 30-second all-out Wingate test.
