Filter by:This study will explore the cerebral mechanisms of impaired awareness of hypoglycemia (IAH) in type 1 diabetics following exposure to experimental recurrent hypoglycemia (HG). To induce IAH, patients with T1D identified to have normal awareness of hypoglycemia (NAH) will undergo three 2-hour long hypoglycemic clamps. Neurochemical profiles will be measured by high field MRS before and after induction of IAH. Subject glycemic variability for 2 weeks and activity/sleep for 1 week before each study will be monitored as all factors have been shown to alter responses to HG.
There is little known about menopause in African women, whose phenotype differs to Caucasian women, and no data is available on middle-aged black South African men. Accordingly, the study aims to examine the changes in sex hormone levels over the menopausal transition in women, and in men of the same age, and explore the effects on body fat distribution and insulin sensitivity and secretion, dissecting the specific roles of glucocorticoids and inflammatory mediators, in the context of HIV. Research questions and hypotheses: 1. Does the decrease in sex hormones that occur with ageing increase circulating cortisol and/or inflammatory markers, and directly and/or indirectly via increases in central fat mass, decrease insulin sensitivity in middle-aged black South African men and women? Hypothesis: The mechanism underlying the decrease in insulin sensitivity (outcome) associated with the decline in sex hormones (exposure) that occurs with ageing is mediated via an increase in centralization of body fat (mediator), which is due to an increase in inflammation and cortisol production. 2. How does HIV alter the relationship between sex hormones, inflammation and cortisol levels, and subsequently body fat distribution and insulin sensitivity? Hypothesis: HIV infection will exacerbate the effects of the decline in sex hormones with ageing, leading to further increases in inflammation and cortisol production, and a consequent increase in the centralization of body fat and decrease in insulin sensitivity. 3. Does adipose tissue glucocorticoid and inflammatory gene expression differ between pre- and post-menopausal women, with and without HIV, and how do these relate to body fat distribution and insulin sensitivity and secretion? Hypothesis: Adipose tissue estrogen receptor beta (ERĪ²), 11-beta hydroxysteroid dehydrogenase type 1 (11HSD1) activity and pro-inflammatory markers will be higher in post- compared to pre-menopausal women, which will be exacerbated by HIV infection. This will be associated with down-regulation of subcutaneous adipose tissue (SAT) adipogenic genes, increased visceral adipose tissue (VAT), a decrease in insulin sensitivity and secretion, and consequently an increased risk for type 2 diabetes (T2D).
The ROTO track® is an electronic injection form and injection log for keeping track of injection sites in the abdominal region. The device attaches directly to the insulin pen and activates whenever the insulin pen is picked up. Small LED lights on the device will indicate where the next injection site is according to the individual patient's injection plan. By moving the pen and device to an "anchor point" in front of the navel, the device is able to start tracking where the insulin pen is being moved to. The device additionally contains a haptic interface to indicate to the user when the device has been moved to the next area in the injection plan. The device registers the location, the time and the dosage automatically when the patient injects insulin with the pen The rationale of the trial is that the ROTO track® can help patients rotate their injections sites and that this will provide the healthcare system with a new cost-effective tool for improving insulin injection techniques.
The study is done to compare how faster aspart is taken up, broken down and removed from the body between different age groups (children [6-11 years], adolescents [12-17 years] and adults [18-64 years]) who have diabetes. The blood sugar (glucose) lowering effect of faster aspart will also be investigated after consuming a meal replacement drink. The effects of faster aspart will be compared to the effects of NovoRapid®.
This study will compare LY900014, a drug that lowers blood sugar, with insulin lispro (Humalog). Both drugs will be given by injection under the skin of the abdomen. This study will be conducted in participants with type 1 diabetes to investigate how quickly and how much LY900014 is absorbed and the effect of LY900014 on blood sugar levels in comparison with insulin lispro. The study will last about 3 to 6 weeks for each participant, not including screening.
Endoscopic Sleeve Gastroplasty (ESG) is an endoscopic minimally invasive weight loss procedure where a commercially available, FDA approved, full-thickness endoscopic suturing device (Overstitch; Apollo Endosurgery, Austin, TX) is used to reduce the stomach volume by 80% through the creation of a restrictive endoscopic sleeve. This is accomplished by a series of endoscopically placed full-thickness sutures through the gastric wall, extending from the antrum to the gastroesophageal junction. Up to 200 participants at 9 locations in the United States will participate in this study. The ESG procedure has been performed clinically since 2013 in the United States. The investigators are completing this study to compare how effective the ESG is for achieving long-term weight loss when compared to lifestyle modification only, as well as to evaluate the long-term safety and durability of the procedure and its impact on quality of life. Results of this research may help support having this procedure covered by health insurance plans for future patients.
This study uses an intervention mixed methods design. The overall purpose is to improve medication adherence and assess the clinical impact on diabetes outcomes among patients with uncontrolled diabetes. We will examine if usual care combined with a clinic-based health literacy/psychosocial support intervention improves medication adherence compared to usual care alone. A randomized controlled trial will be conducted at William S. Middleton Memorial Veterans Hospital in Madison, targeting individuals with uncontrolled diabetes. The patient-centered health literacy intervention will focus on enhancing patients' self-efficacy and addressing patients' negative beliefs in medicine and illness.
Recent epidemiological studies show that egg consumption is associated with insulin resistance and altered glycemic control. For this study, the investigators hypothesize that this association is due to dietary patterns associated with egg consumption, such as saturated fat, and not the consumption of eggs per se. This study will be conducted in two parts that will be conducted simultaneously. Part I will utilize an ecological momentary assessment approach in which dietary patterns associated with egg intake will be determined using an objective measurement of food intake called remote food photography method. In Part II, a randomized partial crossover study will be conducted on the same sample of subjects to test the effects of egg consumption, saturated fat consumption, and consumption of the combination of eggs and saturated fat on glucose, insulin, and hunger and satiety hormone levels.
To assess the relationship between serum endostatin (ES) and Coronary artery calcification (CAC) in type 2 diabetic (T2DM) patients.
The aim of this study is to analyse the effect of a diet with a moderate amount of carbohydrates and compare it with a traditional diabetic diet with a higher content of carbohydrates on mean glucose level, high and low glucose levels, and the risk of ketoacidosis in patients with type 1 diabetes. The glucose levels will be measured by blinded continuous glucose monitoring (CGM). The trial has a cross-over design and 12 weeks in duration, where patients will be randomized to; 1) a diet with moderate carbohydrate content for 4 weeks and 2) a traditional diabetes diet for 4 weeks and with a wash-out period between for 4 weeks. The two diets will both be healthy and planned by a dietitian. There will be 50 subjects included in the study.
