Active clinical trials for "Magnesium Deficiency"

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.

Based on the magnesium (Mg) tolerance test, the "gold standard" test of Mg status, more than 50% US participants had Mg deficiency. Observations suggest that the associations between high Mg intake and disease risks may completely differ by the underlying Mg status. Due to major limitations, the Mg tolerance test is not used in conventional clinical practice and rarely used in research. Instead, serum Mg is used for clinical diagnosis. However, serum Mg performs very poorly at identifying those with Mg deficiency. There is a great need to develop implementable, sensitive, and specific biomarkers which can be easily used for identifying people with Mg deficiency. It is known that DNA methylation changes are inducible by environmental exposures, including nutrients, and reversible when the exposure disappears. We propose to identify 5-hmC/5-mC biomarkers for Mg deficiency by a 4- phase EWAS study in the "Personalized Prevention of Colorectal Cancer Trial [PPCCT, R01CA149633; PI, Dai & Yu]" with a total of 240 participants. Mg tolerance test will be used as the gold standard. Finally, using newly identified biomarkers, we will evaluate if 12-week Mg treatment reduces TRPM7 expression, essential in Mg homeostasis and colorectal carcinogenesis, in rectal tissues only among those with Mg deficiency.

Professional Applied Kinesiology (PAK) is a system which attempts to evaluate numerous aspects of health (structural, chemical, and mental) by the manual testing of muscles, combined with other standard methods of diagnosis. It leads to a variety of conservative, noninvasive treatments which involves joint manipulations or mobilizations, myofascial therapies, cranial techniques, meridian and acupuncture skills, clinical nutrition and dietary management, counseling skills, evaluating environmental irritants, and various reflex techniques. The expanded validity of the manual muscle test has been extensively described.elsewhere, including by one of the Co-Principal Investigators (Anthony Rosner). Details of Applied Kinesiology and its adjunctive procedures are prescribed by an International College of Applied Kinesiology Board of Examiners, cited for its scholarly and scientific activities. A convenience sample of 40 patients, ages 18-75, will be administered the magnesium muscle stretch test with blood drawn at the time of the individual's visit. For the muscle test, uniformity of the examiner's force application is to be confirmed with a force transducer, while the clinician's judgment as to whether the muscle test is positive (facilitated) or negative (inhibited) will be confirmed by electrogoniometry, the procedures for both the force transducer and electrogoniometer having been established by one of the Co-PIs (Anthony Rosner) previously. The blood sample is to be submitted to LabCorp for the measurement of red blood cell levels of magnesium. Coded results of the muscle test and magnesium blood levels are to be correlated by an experienced statistician who is blinded to the patient's identity.

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.

Insufficient clinical evidence correlates the progression of diabetic kidney disease with electrolyte homeostasis in patients diagnosed with type 2 diabetes mellitus (T2DM), especially in the United Arab Emirates (UAE) population and what are the most effective interventions to slow chronic renal failure progression. In our research, we test the hypothesis that low serum magnesium and potassium levels are directly associated with the decline of kidney function in diabetic patients who did not have severely impaired renal function at baseline. In addition, we describe the effect of long-term multifactorial adherence interventions on medication adherence, diet adherence and follow-up visits using a telemedicine approach such as mobile applications in reducing the progression of chronic kidney disease and other diabetes-related complications. This study is a single-blind randomized control trial to demonstrate the causal relationship between potassium and magnesium levels and estimated glomerular filtration rate (eGFR) decline. The intervention group will be evaluated for manifestations of electrolyte imbalance and correction of serum magnesium and/or potassium levels will be initiated based on the last updated laboratory test. Moreover, they will receive education to reinforce diet and exercise changes at each follow up visit by a specialized dietitian with pharmacist-led comprehensive medication therapy management utilizing multifactorial adherence interventions to measure potential drug-drug or drug-food interactions, as well as medication and follow-up adherence through an integrated mobile application and fixed medication possession ratio (FMPR). This research is under progress, and summary of its findings will be reported. This study will suggest if additional national monitoring guidelines may be warranted. In addition, it will reduce diabetic burden, medication cost in UAE and improve patient satisfaction by reducing or delaying the progression of diabetic kidney disease in diabetic patients.

We wish to determine to what extent magnesium, thiamine and transketolase activity are affected by the Systemic Inflammatory Response (SIR). The knee arthroplasty model affords the ideal study design, as surgery generates an inflammatory response. Blood samples are drawn preoperatively and for up to four days post operatively, and again at three months post-operation.

The reported incidence of hypomagnesemia is approximately 2% in the general population. Hypomagnesemia is a common problem, occurring in nearly 10%of general hospitalized patients and 17% of hospitalized cancer patients. A higher incidence, up to 60% to 65%, has been found among intensive care unit patients. Hypomagnesemia can potentially cause fatal complications including ventricular arrhythmia, coronary artery spasm, and sudden death. It also associates with increased mortality and prolonged hospitalization. Magnesium exists in three different forms in the body. In serum, 5-14% of the magnesium is reported to be complexed with anions such as phosphate, bicarbonate, and citrate, 19-33% is reported to be protein-bound (mainly to albumin), and 55-67% is found in the free ionized fraction. Because the amount of bound or complexed Mg can vary significantly, especially in illness, the ionized magnesium can vary in an unpredictable way. Conventional laboratory testing typically only measures total serum magnesium, which is often not reflective of ionized magnesium. Unlike ionized calcium, which is commonly measured and is also readily calculated from the total calcium and albumin levels, ionized magnesium is neither commonly measured nor easily calculated. One study reported that the level of ionized magnesium cannot be predicted by analysis of total magnesium and that the levels of ionized magnesium vary upon different pathophysiological conditions and between individuals. Furthermore, measurement of ionized magnesium in serum might be of great impact in patients for whom magnesium status is required, and the correlation of ionized magnesium and total magnesium is weak in patients for whom magnesium status is required as a whole, and this is the reason why the ionized magnesium should be measured directly. To date, most of the clinical studies were evaluate the effect of hypomagnesemia on the outcome after surgery using the levels of total serum magnesium. However, the portion of extracellular magnesium that is physiologically active is in the various process is ionized magnesium. So, it is important to evaluate the level of ionized magnesium in surgical patients to predict the outcomes after surgery. Unfortunately, clinical trial regarding the effect of the concentrations of ionized magnesium on the surgical patients is limited.

The objective of this study is to determine the role of magnesium on bone and vitamin D metabolism in patients receiving anti-epileptic medications.

Ionized magnesium variation is measured during a normal day and again during a day with an exercise protocol of 90 minutes.
