Filter by:This is a feasibility study to examine the treatment with Metformin, vitamin D with calcium supplement for insulin resistance in obese, black, female teens. The association of low vitamin D levels and decreased insulin sensitivity has been established. Thus, the specific aims of this study are: Specific aim 1: To examine the effect of an 8-week treatment with vitamin D and calcium supplementations on diabetes-related risk factors in obese, black, female teens. Hypothesis 1a: In obese, black, female teens with both insulin resistance and vitamin D deficiency, treatment with vitamin D and calcium supplementation will significantly improve measures of insulin resistance and sensitivity (as determined by the homeostatic model assessment for insulin resistance and whole body insulin sensitivity index measures) when compared to controls not receiving vitamin D and calcium. Hypothesis 1b: In obese, black teen females with both insulin resistance and vitamin D deficiency, treatment with vitamin D and calcium supplementation will significantly improve measures of cardiovascular disease (decreased BMI and improved triglycerides and LDL) when compared to controls not receiving vitamin D and calcium. Specific aim 2: To determine if the addition of Metformin to the 8-week treatment with vitamin D and calcium supplementations improves diabetes-related risk factors in obese, black, female teens. Hypothesis 2a: In obese, black, female teens with both insulin resistance and vitamin D deficiency, treatment with Metformin, vitamin D, and calcium supplementation will significantly improve measures of insulin resistance and sensitivity (as determined by the homeostatic model assessment for insulin resistance and whole body insulin sensitivity index measures) when compared to standard of care or treatment with vitamin D with calcium supplementation alone while controlling for dietary intake of vitamin D and calcium. Hypothesis 2b: In obese, black, female teens with both insulin resistance and vitamin D deficiency, treatment with Metformin, vitamin D, and calcium supplementation will significantly improve measures of cardiovascular disease risk (as determined by the decreased BMI, improved triglycerides and LDL) when compared to standard of care or treatment with vitamin D with calcium supplementation alone while controlling for dietary intake of vitamin D and calcium.
The purpose of this study is to study the relationship between insulin and glucose action and neuropsychological functioning (memory, attention, general thinking abilities) in persons with depression.
The investigators here propose to perform a prospective randomized intervention trial in post-menopausal women to investigate the endocrine network, which contributes to the changes in skeletal muscle mass during weight loss.
The purpose of this study is to examine the effects of consumption of sugar-sweetened beverages on blood triglycerides and cholesterol, cholesterol concentrations, and the body's sensitivity to insulin.
We will test the safety of a new class of anti-diabetes compounds (DPPIV-inhibitors) in people living with HIV. Future trials will examine efficacy for treating diabetes and reducing cardiovascular disease risk in people living with HIV.
The purpose of this study is to evaluate how Vitamin D affects endothelial function, inflammation, lipids, insulin resistance, vitamin D levels, and PTH.
Metabolic syndrome is a highly prevalent condition characterized by visceral obesity, abnormalities of glucidic and lipid metabolism, and increased risk for cardiovascular events. Such findings appear to be associated with a decrease in insulin sensitivity. Management of metabolic syndrome is currently aimed at treating individual components of the disease without addressing this underlying pathophysiologic mechanism; this translates into multidrug regimens, high costs and patient compliance issues. Armolipid Plus (an association of berberine 500 mg, red yeast rice titled in 3 mg monacolin K,policosanol 10 mg,coenzyme Q10 2 mg,astaxanthin 0,5 mg,folic acid 0,2 mg) has been found to be effective at reducing blood cholesterol and triglycerides, and at improving endothelial function; subgroup analyses also suggested a benefit on indices of insulin resistance. Aim of the study is to evaluate the effects of Armolipid Plus on insulin sensitivity and on the diagnostic parameters of metabolic syndrome. 60 patients will be enrolled in this randomized, double-blind, placebo-controlled trial; active treatment will consist of Armolipid Plus (1 tbl qd). Primary end point will be the reduction of the insulin/glucose ratio, both after overnight fast (HOMA index) and after an oral glucose tolerance test (OGTT).
Substudy examining cardiovascular and metabolic risk factor change in children at high risk for future atherosclerosis who are enrolled in a pilot intervention using novel gaming and exercise activities to increase physical activity.
The main purpose of this study is to assess the efficacy of metformin in abrogating androgen deprivation therapy (ADT) induced insulin resistance as measured by homeostasis model assessment (HOMAIR) in men with non-metastatic prostate cancer.
A Prospective Double-Blinded, Placebo Controlled, Randomized Trial comparing a single dose of Vitamin D (Colecalciferol) 300.00UI to placebo on patients with insulin resistance. Primary Outcome: Blood glucose and homeostasis model assessment for insulin resistance (HOMA-R) after 90 days. Study hypothesis: Vitamin D treatment may improve insulin resistance and decrease glucose level, since there is an association between hypovitaminosis D and increased insulin resistance.
