Filter by:Metabolism is controlled by macro- and micronutrients. Protein-rich diets should lead to latent acidosis at tissue level with further negative implications. Food supplements with alkaline salts are available and popular pretending to prevent these changes. Within a randomized double-blind placebo-controlled trial, the investigators tested the hypotheses 1) that a 4-week protein-rich diet induces a latent tissue acidosis and 2) an alkaline supplement can compensate this. Acid-base balance and important metabolic parameters were determined before and after 4 weeks of supplementation by peripheral blood samples, indirect calorimetry and muscle microdialysis before and after a protein-rich test meal.
This study will evaluate respiratory function in people with fibromyalgia and whether or not breathing patterns in this patient group can be explained by stress, emotional or biomechanical variables. In addition, examine the relationship between physical ability and lactate values.
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.
The administration of intravenous fluids is ubiquitous in the care of the critically ill. Commonly available isotonic crystalloid solutions contain a broad spectrum electrolyte compositions including a range chloride concentrations. Recent prospective, randomized trials have shown improved patient outcomes with the use of balanced crystalloids compared to saline. There have not been large randomized studies comparing acetate buffered balanced crystalloids to non-acetate buffered balanced crystalloids in the critically ill. BASE will be a pilot study for a large, cluster-randomized, multiple-crossover trial enrolling critically ill patients from the Medical ICU at Vanderbilt University from June 2018 until January 2019. The primary endpoint will be plasma bicarbonate concentration between Intensive Care Unit admission and hospital discharge.
Lactic acidosis is a common phenomenon occurring during orthotopic liver transplantation (OLT), especially during the anhepatic and early postreperfusion phases. However, little drugs effectively decrease the degree of lactic acidosis when it happens. The aim of this study is to explore whether glucose-Insulin-Potassium(GIK) infusion can relieve metabolic acidosis and improve perioperative outcome in patients undergoing OLT.
Alterations of acid-base equilibrium are very common in critically ill patients and understanding their pathophysiology can be important to improve clinical treatment. The human organism is protected against acid-base disorders by several compensatory mechanisms that minimize pH variations in case of blood variations in carbon dioxide content. The aim of the present study is to quantify the buffer power, i.e. the capacity to limit pH variations in response to carbon dioxide changes, in critically ill septic patients and compare these results with data collected from healthy volunteers.
Longitudinal, exploratory, natural history study of patients with MMA due to mut deficiency and PA to characterize the changes in blood disease biomarkers over time and the frequency and severity of clinical events related to their disease.
Patients who suffer Alcohol Use Disorder (AUD) have a 30-80% incidence of thiamine deficiency causing Wernicke's Encephalopathy (WE). Intravenous (IV) thiamine replacement is standard practice in the treatment of alcoholic patients presenting to the Accident & Emergency (A&E) department, however routine co-supplementation with magnesium (administered IV as magnesium sulphate ), which is required as a co-factor for thiamine in some metabolic processes, e. g. on the activity of the enzyme transketolase in red blood cells, is not routine practice in the treatment of these patients. Without correction of concomitant magnesium deficiency there may be impaired utilisation of thiamine resulting in a failure to treat WE. This study is designed to determine if administration of magnesium to AUD patients affects red cell transketolasae and serum lactate concentrations by itself, or only acts to increase the effect of thiamine on the activity of this enzyme.
Metabolic acidosis is associated with vascular endothelial dysfunction and is a common complication in patients who have received a kidney transplant. Kidney transplant recipients (KTR) with lower serum bicarbonate levels, even within the normal range, have an increased risk of graft loss and mortality. The investigators propose a prospective, double-blind, randomized, placebo-controlled, 18-week crossover pilot study to examine the effects of sodium bicarbonate on vascular endothelial function, graft function, and cognitive function in 20 KTR patients.
This study is a 40-week, blinded, placebo-controlled extension of Study TRCA-301 (NCT03317444). Eligible subjects who complete the 12-week treatment period in Study TRCA-301 have the option to participate in this extension study evaluating the long-term safety and durability of effect of TRC101 in subjects with non-dialysis dependent chronic kidney disease and metabolic acidosis. Eligible subjects will be treated with TRC101 or placebo once daily (QD) on an out-patient basis for the subsequent 40 weeks. Subjects will continue to receive the same blinded treatment (TRC101 or placebo) that they received in Study TRCA-301.
