Active clinical trials for "Ketosis"

The purpose of this study is to compare the risk of serious adverse events associated with the use of sodium-glucose cotransporter 2 (SGLT2) inhibitors in comparison with the use of dipeptidyl peptidase-4 (DPP-4) inhibitors among patients with type 2 diabetes. More specifically, the investigators will assess the risk of severe urinary tract infection (urosepsis), diabetic ketoacidosis and lower extremity amputation. The investigators hypothesize that the use of SGLT2 inhibitors will be associated with an increased risk of serious adverse events in comparison with the use of DPP-4 inhibitors. The investigators will carry out separate population-based cohort studies using health care databases in seven Canadian provinces and the United Kingdom. Separate study cohorts will be created for each of the three safety outcomes. The study cohorts will be defined by the initiation of a SGLT2 inhibitor or a DPP-4 inhibitor after SGLT2 inhibitors entered the market. Patients will be followed up until the occurrence of an adverse event. The results from the separate sites will be combined by meta-analysis to provide an overall assessment of the risk of serious adverse events in users of SGLT2 inhibitors in comparison to users of DPP-4 inhibitors.

Rationale: During perioperative period, prolonged starvation, surgical stress, acute complications (e.g. infection) and medication changes all promote ketone generation, therefore increasing the risk of ketoacidosis. At present, there is no literature concerning the ketone production in patients undergoing cardiac surgery, regardless of the diabetes status. Objectives: The objectives of this study are to explore the change in blood ketone level during the perioperative period in patients with and without diabetes, to observe the incidence of perioperative ketoacidosis, and to investigate therapy and outcome of patients with perioperative ketoacidosis.

A study to evaluate the prevalence of Acute Kidney Injury (AKI) in patients with Diabetic Ketoacidosis (DKA) and sepsis using data collected prospectively to a patient registry. The primary objective is to compare the prevalence of AKI in sepsis and DKA in different age groups in children and investigate the difference in the prevalence of hyperchloremia in the two groups.Secondary objectives are Compare the prevalence of AKI in sepsis and DKA in different age groups in children and investigate the difference in the prevalence of hyperchloremia in the two groups.

Background: The serum anion gap (AG) is commonly used as a screening tool for acid-base disorders. With modern laboratory techniques using ion-selective electrodes to measure the main electrolyte components of the AG, our definition high AG (HAGMA) should be reviewed. Aim: This study aims to assess the diagnostic value of AG and to determine a diagnostic threshold for HAGMA in a high-prevalence clinical setting. Method: Computerized extraction of anonymised data from electronic medical records was performed. A pre-defined criteria included all inpatients of an acute-care hospital who had measurements for organic acids (lactate, ketone or salicylate) paired with a serum urea, electrolyte and creatinine panel.

The purpose with the study is to follow the fluid shifts that occur during fluid resuscitation of patients with diabetic ketoacidosis. In the study measurements of changes in blood and urine concentrations of Sodium and Chloride as well as blood hemoglobin are used to mathematically calculate changes in distribution volumes of these different endogenous markers.

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.

Compare plasma metabolites following different conditions paired with a dietary MCT beverage over an 8-hour metabolic day protocol in young and older participants.

The objective of this study is to make a comparison between 11C-acetate and 11C-Acetoacetate heart and kidney metabolism

The purpose of this study is to investigate individuals with type 1 diabetes who were disconnected from their insulin pump and insulin therapy was started again after positive ketones (U) in the urine or blood β-hydroxybutyrate.

Hypothesis To define whether stimulation of ATGL and suppression of G0/G1 switch gene occur in the initial phases of diabetic ketoacidosis and thus can be identified as the primary mechanisms behind this life threatening condition. Make a human model for studying ketoacidosis. The investigators plan to reduce in their regular insulin over night. In the morning we administer endotoxin, which together with a relative lack of insulin will initiate ketogenesis - a state of ketoacidosis. On another occasion strict glycemic control is imposed by means of intravenous insulin. The testing is done two separate days with at least 3 weeks in between and patients are admitted to hospital the evening before the day of testing. The investigators use isotopic tracers to determine metabolic fluxes and analyse fat (ATGL, G0/G1 switch gene) and muscle biopsies.
