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.
The primary objective of this clinical trial is to demonstrate the superiority of Natural Calm magnesium powder with respect to absorption when compared to three marketed forms of magnesium (two magnesium bisglycinate powders and magnesium citrate capsules). The primary endpoints were serum magnesium AUC (0-8h) and urine magnesium AUC (0-8h) after a single dose of 150 mg elemental magnesium.
The purpose of this study is to investigate the effects of a combined vitamin D and magnesium supplementation on parathyroid hormone and cardiometabolic health in persons living with obesity.
Hypomagnesemia is a common entity in the inpatient and outpatient setting. in previous retrospective study hypomagnesemic patients have higher mortality and longer hospitalization. whether hypomagnesemia is merely a marker of poor prognosis, or whether replacing it can improve outcomes is unclear. The current standard of care is to discharge these patients without workup or further treatment, even if patients had received intravenous therapy while hospitalized. The investigator wish to examine prospectively whether giving replacement therapy affects mortality, length of hospital stay and overall well-being. In order to replete intracellular levels and replete magnesium stores, magnesium should be given for several months.
The goal of clinical trial is to evaluate the effect of one month of consumption of mineral water rich in magnesium or not on perceived stress, duration and quality of sleep in healthy consumers having magnesium daily intakes below the recommended dietary allowance (RDA).
Ionized magnesium variation is measured during a normal day and again during a day with an exercise protocol of 90 minutes.
The investigators propose a preventive strategy that may reduce the risk of placental vascular disease and its negative consequences for both the fetus (e.g., poor fetal growth or stillbirth)and mother (e.g., the hypertensive disorders of pregnancy), and which, in turn, should reduce the need for indicated preterm delivery. This strategy is a multicenter, randomized double-blind, placebo-controlled clinical trial (RCT) comparing magnesium citrate supplementation with placebo, each starting at 12 to 20 weeks gestation and continued until delivery. Magnesium citrate is a safe and inexpensive compound that is easily absorbed by the intestinal tract. The results of this RCT may be especially relevant in low and middle income countries that have high rates of prematurity, and limited resources for acute newborn and maternal care.
The investigators aim to recruit 60 women who have agreed to participate in an existing randomized, double-blind, placebo-controlled trial (Treatment of Vitamin D Insufficiency, HSC 2009-0055). In this trial, the investigators propose to evaluate the associations between magnesium intake, magnesium stores, fractional magnesium absorption and calcium homeostasis. The investigators will stratify 60 subjects in the sub-study, ensuring that approximately 20 subjects are randomized into each treatment arm (placebo, low-dose and high-dose vitamin D). The investigators already assess calcium homeostasis throughout the study by measuring bone mineral density, fractional calcium absorption, serum and urine calcium levels, among other tests. In the sub-study of 60 women, the investigators will evaluate whether habitually higher magnesium intake increases or decreases fractional calcium absorption. The investigators will evaluate the interplay between magnesium stores, vitamin D levels and serum parathyroid hormone levels. The investigators will directly assess magnesium stores using serum magnesium and 24-hour urine magnesium levels, and will measure magnesium absorption using the dual stable isotope approach.
