7 Clinical Trials for Various Conditions
This is a randomized, double-blind, placebo-controlled parallel trial designed to evaluate the effectiveness of Qualia Magnesium+® supplementation on red blood cell (RBC) magnesium levels in adults aged 21 and older. Approximately 100 participants with baseline RBC magnesium levels below 6.0 mg/dL will be randomly assigned to receive either Qualia Magnesium+ or a placebo. Participants will take 2 capsules daily in the evening, with or without food, for a duration of 12 weeks. The primary outcome is the between-group change in RBC magnesium levels from baseline to Week 12. Secondary outcomes include assessments of sleep quality, perceived stress, magnesium status, and safety and tolerability. Data collection will occur through lab bloodwork and electronic questionnaires.
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 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.
The objective of this study is to determine the role of magnesium on bone and vitamin D metabolism in patients receiving anti-epileptic medications.
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.
To determine whether acute ionized hypomagnesemia and hypocalcemia immediately following foscarnet infusions can be lessened or eliminated by prior infusion of magnesium sulfate. To determine whether reductions in ionized magnesium, ionized calcium, and parathyroid hormone levels following foscarnet infusions are lessened by preinfusion of magnesium sulfate. To evaluate the safety of intravenous magnesium sulfate prior to foscarnet infusion by monitoring blood pressure, heart rate, and heart rhythm. To characterize the effect of magnesium sulfate on foscarnet blood levels and urinary excretion of calcium, magnesium, phosphate, and foscarnet.
Insomnia is not a natural part of aging but is higher in older adults because of a variety of factors common in later life. One of these factors may be a deficient magnesium status. This study will look at whether or not magnesium supplementation will improve sleep.
