Active clinical trials for "Hyperglycemia"

This study is focused on assessing potential health benefits of daily consumption of potatoes, specifically its resistant starch content (i.e. nondigestible carbohydrate), on blood vessel and gut health function in adults with metabolic syndrome. It is expected that the daily consumption of potatoes for two weeks, within a diet that follows the Dietary Guidelines for Americans, will improve blood vessel function in association with decreasing gut permeability ("leaky gut") that results in the absorption of bacterial toxins that reside in the intestine. Outcomes will therefore support dietary recommendations for potatoes to support vascular and gastrointestinal health.

Switching patients with HIV infection from tenofovir disoproxil fumarate (TDF) to a tenofovir alafenamide (TAF) based drug regimen can provide many safety benefits including preserving bone mineral density and kidney function. This study will examine metabolic changes that patients may encounter due to the switch in medication regimens and the maintenance of viral suppression.

The main purpose of this study is to determine if exercise preserves vascular function during hyperglycemia. All subjects will consume a sugary beverage three times daily for seven days. Subjects will be randomly assigned to either the glucose with (GLU+EX) or without (GLU) structured exercise group.

Evaluation of the effect of peri-operative continuation of oral metformin therapy on the incidence of perioperative hyperglycemia compared to standard preoperative cessation of oral metformin therapy 24h before surgery.

The purpose of this prospective study is to determine if trial use of a Dexcom G6 CGM system for a 10 day wear period in high risk, poorly controlled pediatric Type 1 diabetes patients increases uptake of personal CGM use, and improves short-term time in range glucose control.

This study, conducted at the NIH Clinical Research Unit (CRU) at the Phoenix Indian Medical Center, will compare the effects of two methods of bariatric surgery, the adjustable BAND and Roux-en-Y gastric bypass, on insulin. Bariatric surgery is a treatment for achieving and maintaining weight loss. The study will look at how this surgery might improve how insulin (a hormone important for regulating blood sugar levels) is made and works in the body and the possible role of changes in other hormones produced by the gut (stomach and intestines). People between 18 and 50 years of age who are scheduled to have either laparoscopic adjustable BAND or Roux-en-Y gastric bypass surgery may be eligible for this study. Candidates are screened about 4 to 6 weeks before their surgery with a medical history, blood tests and an oral glucose tolerance test for diabetes. Participants spend 4 days at the CRU or 2 days overnight and an out-patient visit approximately 4 to 6 weeks before their surgery and again 3 to 6 weeks after their surgery. They return for a 4-6 hour visit at the CRU at 6 months, 1 and 2 years after surgery and for half-day outpatient visits at 3, 4 and 5 years after surgery for the following procedures: Blood and urine tests, including a pregnancy test for women. (4-day and 2-day admissions and years, 3, 4 and 5) DEXA, an x-ray scan to determine body fat content. (4-day and 2-day admissions and years, 3, 4 and 5) MRI scan to measure fat tissue in the abdomen. (4-day and 2-day admissions and years, 3, 4 and 5) Intravenous (I.V.) glucose tolerance test for risk of obesity and diabetes. A sugar solution is given through a needle in a vein of one arm and blood samples are drawn through another needle in a vein in the other arm. (4-day admissions) Meal test to measure blood sugar and insulin and gut hormone levels after a meal. After an I.V. line is placed in an arm vein, the subject eats breakfast over 20 minutes. Blood samples are collected halfway through the meal, at the end of the meal, and at 15, 30, 60, 90, 120 and 180 minutes after completing the meal. Subjects fill out questionnaires on feelings of hunger and fullness before, during and after the meal test. (4-day and 2-day admissions) Glucose clamp test to measure the effect on the body of insulin given through a vein. An I.V line is placed in a vein in the arm and in a vein of the hand on the other side of the body. While insulin is infused through one I.V., blood sugar levels are checked every 5 minutes and a sugar solution is given into a vein as needed. A radioactive sugar is also infused very slowly over 4 hours to determine how much sugar the body produces by itself. (4-day admissions)

The purpose of this study is to evaluate safety and accuracy of the IVBG System (the "System") when used to track blood glucose in insulin treated subjects with diabetes mellitus in an in-clinic setting for up to 72 hours (per subject). Reference blood glucose measurements will be collected across the entire reportable range of the System (e.g., 40 400 mg/dL) with adequate sampling at the upper and lower ends of this range. IVBG System accuracy will primarily be assessed relative to ISO 15197 criteria (i.e., within ±15 mg/dL at YSI glucose levels < 75 mg/dL, and within ±20% at YSI glucose levels >75 mg/dL).

High blood pressure, elevated blood glucose and high cholesterol are related to the increased risk of stroke and heart disease. Many studies have shown that this risk can be significantly reduced by lowering blood pressure, blood glucose and cholesterol levels. Through a collaborative effort between Calgary Safeway pharmacists and Calgary Health Region family physician PCN's, U-CHAMP will deliver a program to assist in the identification and management of people with elevated blood pressure, blood glucose and cholesterol and through this effort, reduce the risk of heart disease and stroke in the urban Calgary population aged 18-85 years.

As a phase 0 clinical trial, we will learn how kombucha influences glucose metabolism in humans.

A multi-center, randomized, prospective, non-significant risk study to compare the impact of the FreeStyle Libre 2 Flash Glucose Monitoring System to the current standard of care (SMBG, self-monitoring of blood glucose) on reducing time above 180 mg/dL in subjects with type 2 diabetes who are not adequately controlled on their existing oral anti-diabetes medication regimen.
