Active clinical trials for "Hyperglycemia"

Type 2 diabetes (T2D) is an emerging epidemic in sub-Saharan Africa, with an estimated prevalence of 6%. With around seven million cases of T2D in 2000, it is anticipated that over 18 million Africans will have the disease by 2030. In South Africa the prevalence of T2D in people of African descent has been reported to be between 3-10%. However, there have been limited studies on diabetes epidemiology in South Africans using currently employed World Health Organization (WHO) criteria. To assess the burden of T2D and associated risk factors in South Africa, we are establishing the Durban Diabetes Study (DDS) - a population-based cross-sectional study in the city of Durban (the eThekwini municipality) to be undertaken in 1,200 participants of African descent. In-depth health questionnaire responses, biophysical measurements and blood and urine samples will be gathered from these participants. These data will allow researchers to estimate the population prevalence of T2D and associated risk factors in the region. The infrastructure created for this cross sectional study has the potential to serve as a strong framework for future research initiatives and public health interventions within the region.

Hyperglycemia is a common complication of corticosteroid (cortisone) therapy. It is estimated that more than a third of patients with chronic pulmonary disease (COPD) exacerbation (16). Despite its frequency, the impact of corticosteroid-induced diabetes on clinical outcome and mortality is not known. A computerized search of biomedical journal literature from MEDLINE, PubMed, and Ovid from 1966 to 2006 provided very little information on the prevalence and outcome of corticosteroid-induced diabetes in patients with COPD. Therefore, the present study aims to evaluate the impact of corticosteroid-induced diabetes on clinical outcome in patients with COPD exacerbation. We will perform a retrospective chart review of all patients admitted to the hospital with COPD exacerbation from 1/01/05 to 06/30/06 at Grady Memorial Hospital. Medical records of all patients with COPD exacerbation treated with corticosteroids will be analyzed. Data on demographics, laboratory values, mortality rate, rate of hypoglycemic events, length of stay, as well as disposition at discharge will be analyzed.

Surgery performed during general anesthesia induces a stress effect on the body. Our plan is to identify population at risk of hyperglycemia during perioperative period.

Patients in three hospitals in Sweden who will have knee arthroplasty surgery for the first time are invited to participate in the study, approximately 2000 patients. The fasting glucose value (fP-glucose) is obtained via a blood sample the day after the knee arthroplasty surgery. The sample is analyzed and the glucose value obtained is documented and sent to the Swedish Knee Arthroplasty Register (SKAR). In the SKAR there is information on patient characteristics, diagnosis, prosthesis, anesthetic form and primary and secondary operations, etc. The unique personal numbers of the included patients are submitted to the National Board of Health and Welfare, which matches the cohort with the Patient Register to identify adverse events, re-admission and death in a year after the surgery. SKAR has carried out several interactions with the National Board of Health and Welfare, and possesses clinical expertise as well as registers and biostatistics expertise. Incidence calculation of the proportion that develops elevated glucose levels after surgery and Cox regression for group comparison (elevated glucose vs. non-elevated) taking into account factors within groups such as age, gender, etc. This is a register-based observation study. Since the incidence of elevated glucose value after a knee prosthesis operation is not known, we are planning for a representative selection from three major prosthetic clinics in Sweden. Regarding the secondary purposes, our ability to answer these depends on the presence of elevated glucose levels. The inclusion start in January 2019 and lasts for one year. Incidence calculations can be made as soon as all patients are included, but 90-day data from the patient register can reasonably be completed

This project will test a unique botanical formula designed to inhibit alpha amylase (the primary starch degrading digestive enzyme) and inhibit sucrase (the primary sucrose degrading digestive enzyme) in order to reduce acute post prandial glycemia regardless of nutritive carbohydrate source.

Malnutrition or its risk is common among older people. To maintain adequate nutrition, increased meal frequency is important. In addition to main meals, regular consumption of nutrient- and energy-dense snacks is recommended. The study examines the post-meal responses to dairy- and berry-based snacks tailored for older people. The plasma concentrations of glucose, insulin and free fatty acids are measured during three hours after snack consumption. In addition, subjective satiety responses and heart rate variability are recorded.

With the increasing prevalence of diabetes in pregnancy it is necessary to design a simple, sensitive, cost effective method for screening of hyperglycaemia in pregnancy specially in resource constrained settings. There is no universally agreed screening and diagnostic criteria to detect hyperglycemia in pregnancy. In present study, DIPSI (non-fasting OGTT) is compared with fasting oral glucose tolerance test (OGTT) to evaluate sensitivity and specificity of both methods in our population.

The objective of this project is to determine the prevalence of hypertension, hyperlipidemia and hyperglycemia in the pediatric population with sickle cell disease who are obese in Mississippi compared to those pediatric patients with sickle cell disease who are not overweight/obese. The pediatric hematology department at the University of Mississippi Medical Center (UMMC) has a relatively large population of patients with sickle cell disease who are overweight and obese. This is a paradoxical trend since high-energy expenditure of the body to produce new red blood cells usually results in underweight to normal weight patients. From our previous chart review, the investigators found our pediatric patients with sickle cell disease to have similar rates of overweight and obesity to that of state and national levels. The metrics our team will measure include: blood pressure, blood cholesterol levels and blood glucose levels. The investigators expect to find higher rates of hypertension, high cholesterol and high glucose levels in the overweight and obese patients with SCD compared to that of underweight and normal weight. Our ultimate goal for follow up projects will be to determine the baseline risk of hypertension, hyperlipidemia and hyperglycemia in this population so we can then determine effective, sustainable interventions for weight and the co-morbidities that come with increasing weight status. Our goal would also be to educate the patient and families on these interventions and provide them with resources, which could lead to an overall improvement in health and patients quality of life.

A learner-centered diabetes survival skills self-management education program was provided to adults with uncontrolled diabetes in the hospital and generated preliminary evidence of impact on medication adherence and a trend toward reduction in hospital and emergency department admissions.

Results from a large number of studies in humans have shown that diets rich in foods that give lower glucose response bring lower risk of type 2 diabetes. Polyphenols, naturally found in fruits, vegetables and grains, have shown the potential to attenuate post-prandial blood glucose spikes following a carbohydrate-rich meal, through partial inhibition of the main enzymes of carbohydrate digestion and reduction in glucose and fructose transport from the gut after digestion and by enhancing the insulin action after glucose reaches the bloodstream. This study is designed to determine whether polyphenols, as normally and naturally present in food extracts and beverages, added to a carbohydrate-rich meal, can lower blood glucose levels after its consumption, and hence lower its glycaemic index, and if this effect is mediated through effects on insulin and other hormones. The study is designed as an acute, double-blind, randomised, placebo-controlled crossover trial in 24 healthy subjects with normal glycaemic response to white bread. Participants will be asked to consume either white bread with pomegranate juice enriched with extracts from grape seeds and apple peels or white bread with placebo drink. The effects on plasma glucose levels, levels of hormones and other biomarkers involved in postprandial response will be determined over 3 hours after the consumption.
