Impact of ACT-based Interventions on Diabetes-related Outcomes
Diabetes MellitusType 12 moreIndividuals with insulin-treated diabetes can experience psychological difficulties associated with living with and managing the condition. Acceptance and Commitment Therapy (ACT) is being increasingly used to treat these psychological difficulties, with research in this area indicating positive psychological and diabetes-related outcomes (Gregg, Callaghan, Hayes, & Glenn-Lawson, 2007; Shayeghian, Hassanabadi, Aguilar-Vafaie, Amiri, & Besharat, 2016). Given the lack of psychology funding in diabetes care provision, a financially feasible theory-based intervention is much-needed (Diabetes UK, 2008). ACT may be the solution as it can be delivered in smaller modules. The study aims to investigate the effectiveness of two online ACT-based interventions (a mindfulness-based intervention [MBI] and a values-plus-goals intervention [VGI]) on wellbeing, diabetes self-management, coping style and glycaemic control among a sample of adults with insulin-treated diabetes. It also aims to examine whether the interventions are associated with changes in diabetes acceptance and valued living, and whether diabetes acceptance and valued living are associated with the aforementioned outcomes. Participants will be recruited from the diabetes outpatient clinics at Ashford and St. Peter's Hospitals NHS Foundation Trust to take part in the study. They will be randomly assigned to take part in either the MBI or VGI, which are both 4-week interventions. Participants will be asked to complete self-report questionnaires to measure their wellbeing, diabetes self-management, coping style, diabetes acceptance and valued living at the beginning of the study, at the end of the intervention and at a 1-month follow-up. Glycaemic control will be measured at the beginning of the study and at a 2-month follow up. It is hypothesised that both interventions will improve diabetes-related outcomes. It is hypothesised that MBI may be associated with increases in acceptance and more positive emotion focused coping, whereas the VGI may be associated with increased valued living and problem-focused/active coping.
Dapagliflozin During Exercise for the PrevenTion of Hypoglycaemia
Diabetes MellitusType 1There are approximately 400,000 people in the UK who are living with type 1 diabetes (T1DM), of whom 29,000 are children. People with T1DM experience on average 2 episodes of symptomatic hypoglycaemia per week , and exercise (especially aerobic) increases this risk . Strategies to prevent hypoglycaemia during and after exercise include increasing glucose consumption and reducing insulin dose, however overcompensation may result in worsening of blood glucose control. Dysregulated glucagon secretion, manifested as a reduced counter-regulatory response during hypoglycaemia, is a key feature in T1DM, occurring soon after diagnosis. Anecdotal evidence suggests that SGLT-2 (sodium/glucose cotransporter-2) inhibitors (SGLT2i) such as dapagliflozin prevent exercise-induced hypoglycaemia in T1DM. SGLT2is promote glucose excretion without causing hypoglycaemia.Paradoxically, given their mode of action, they increase plasma glucose and stimulate glucagon secretion. Studies in diabetic rats indicate that the physiological counter-regulatory response is suppressed in insulin-treated diabetes, a defect that can be corrected by somatostatin antagonists. The DEPTH trial will test the novel hypothesis that hypoglycaemia results from hypersecretion of somatostatin, and that this defect can be corrected by SGLT2i. As these medications are already in clinical use, our findings may be rapidly translated into practice. Understanding these key processes has the potential to generate novel therapeutic strategies to improve glycaemic control, thereby facilitating a more active lifestyle in people with T1DM.
Low-dose Dasiglucagon for Prevention of Insulin-Induced Hypoglycemia in People With Type 1 Diabetes...
Type 1 DiabetesHypoglycemiaThe aim of the study is to compare the efficacy of low-dose dasiglucagon (Zealand Pharma, Denmark) to oral carbohydrate consumption for prevention of s.c. insulin-induced hypoglycemia in CSII- and MDI-treated people with type 1 diabetes.
Hybrid Closed Loop in High Risk Youth With Type 1 Diabetes
Type 1 DiabetesThe use of insulin pumps and continuous glucose monitors for Type 1 diabetes (T1D) has been shown to improve glycemic control while also decreasing the risk for acute and chronic complications. Unfortunately, there are vast disparities in access to this technology; non-Hispanic black youth with public healthcare insurance are the least likely to have access to these technologies. We propose to conduct a non-randomized interrupted time series study to assess the impact of hybrid closed loop (HCL) insulin delivery in underserved youths with poorly controlled T1D. Patients will complete standard diabetes education before beginning to use this technology and will be followed for 6-months after starting HCL to assess its impact on glycemic control and health-related quality of life.
Effect of Splitting Mealtime Insulin Doses After Mixed Meals High in Fat and Protein
Type 1 Diabetes MellitusThe current management of type 1 diabetes mellitus (T1DM) depends on the use of intensive insulin therapy - either by insulin pump therapy or multiple daily injection (MDI) therapy - and the use of carbohydrate counting to determine the mealtime bolus insulin dose according the carbohydrate contents of each meal or snack. However, several studies reported that the fat and protein contents of the meals can also affect the postprandial blood glucose levels and result in delayed postprandial hyperglycemia especially after high fat and protein meals. There is no widely accepted regimen to calculate insulin required for the fat and protein contents of meals especially for patients using multiple daily injection regimen. This study aims to find a better method to cover the increased insulin requirements following mixed fat and protein meals. The study will compare the effect of splitting mealtime bolus insulin doses into pre-meal and post-meal portions to the standard regimen which involve giving bolus dose depending on carbohydrate content only with additional correction doses 2 to 3 hours after the meal to compensate for the postprandial hyperglycemia induced by fat and protein content of the meals.
A Study to Look at How Safe Insulin NNC0471-0119 is and How it Works in People With Type 1 Diabetes...
Diabetes MellitusType 1This study is looking at the safety of the new medicine, insulin NNC0471-0119, its concentrations in the blood and effect on blood sugar for the treatment of type 1 diabetes. Insulin NNC0471-0119 will be compared to faster aspart. The purpose of this study is to test how insulin NNC0471-0119 is tolerated by participants body, how it is transported in participants bloodstream, how long it stays there and how the blood sugar is lowered compared to faster aspart. Participants will get either the new insulin NNC0471-0119 or faster aspart-which treatment participants get is decided by chance. It is the first time insulin NNC0471-0119 is tested in people. Faster aspart is a globally used medication for treatment of diabetes mellitus. Participants will get one single injection in a fasting state which will take place at the study site. The medicine will be injected under the skin in the stomach. The study will last for about 13-53 days, depending on individual visit schedule. Participants will have four clinic visits with the study doctor, one of which will require an in-house visit period of 3 days. During the in-house visit, two intravenous cannulas will be inserted for sampling of blood and infusion of insulin. Participants cannot be in the study if the study doctor thinks that there are risks to their health. Women: Women cannot take part if they are of childbearing potential.

"MyPlan" - Individualized Eating Patterns for Adolescents With Type 1 Diabetes
Type 1 DiabetesThe purpose of this study is to test the acceptability and effectiveness of an individualized eating strategy as part of diabetes self-management to improve glycemic levels among youth with type 1 diabetes (T1D) and suboptimal glycemic management. Investigators will assess participant acceptability of and adherence to a 6-month individualized eating strategy ("MyPlan") characterized by approximate day-to-day consistency in the frequency and timing of meals and snacks and distribution of carbohydrate throughout the day. Within-individual change in glycemic levels between baseline and 6-months of the study will also be compared. The goal of the study is to inform the design of a future randomized clinical trial to test the addition of the MyPlan eating strategy to ongoing diabetes clinical care among youth with T1D.
