Filter by:The study team is inviting 13 healthy people to complete a study to explore how calcium affects hormones and bones after eating. Participants will be asked to complete two study visits within eight weeks. Before each visit, participants will be asked to not eat or drink (except water) for 9 hours. At each visit, participants will eat the same meal provided by the research team. Along with their meal, they will take a pill - in one session, this will be a calcium supplement, and in the other, a placebo (a pill with no calcium), but they won't know which one they are taking at which session. A phlebotomist will draw blood before the meal and pill, then again several times after eating. Blood draws will take place over three hours. During that time, participants will complete questionnaires about health, diet, and physical activity. Blood will be analyzed to check on various health indicators, like bone health markers and certain hormones, to see how they change after the meal. The difference in these health indicators between the calcium and placebo sessions will help the study team understand the impact of calcium on health after eating. This could help increase knowledge of the impact of calcium on hormones and bone health.
This research was designed in accordance to the Method for Efficacy Assessment of Health Food for Bone Heath. Changes to bone density were measured to evaluate the effectiveness of amorphous calcium carbonate in maintaining bone health.
A comparison between resistive exercise and high intensity interval trainig on calcium and vitamin d in premenopausal women.
COVID-19 infection causes a hypersensitive immune reaction and widespread inflammation in various organs of the body, especially through cytokines in the lungs. This cytokine-mediated widespread inflammation can also affect the parathyroid glands, resulting in impaired parathyroid secretion. Researchers evaluated the levels of parathyroid hormone, calcium, phosphorus, and alkaline phosphatase in patients hospitalized for COVID-19 infection. Researchers excluded patients on intensive care therapy and patients with known parathyroid disease. The researchers examined the association of parathyroid hormone secretion with COVID-19 disease, white blood cells, neutrophil / lymphocyte ratio, C reactive protein, fibrinogen, procalcitonin, ferritin, and D-dimer in these patients. The researchers compared the parathyroid hormone level of healthy people without COVID-19 infection and known parathyroid disease with the parathyroid hormone level of Covid-19 patients.
