Filter by:Advanced glucose monitoring systems have revolutionized diabetes care and enabled people with diabetes to achieve better diabetes control with reduced risk of hypoglycaemia. Continuous glucose monitoring (CGM) systems provide real-time glucose monitoring and alarms when glucose approaches extreme readings (hypoglycaemia and hyperglycaemia) or when the change in glucose is rapid. All available CGM systems, except Dexcom G6, require daily calibrations with capillary glucose readings in order to attain accuracy of glucose readings. Decom G6 system is not widely accessible and only available in certain countries. Flash glucose monitoring systems (Flash) provide glucose readings when users actively scan their sensors. FreeStyle Libre (FSL) is the only Flash glucose monitoring system currently available in market. FSL is factory calibrated and sensors are ready to use after placement and initiation. The two main differences between Flash and CGM are user interaction and the alarm facility. While CGM provide real-time glucose readings, Flash is user-dependent for actively scanning and understanding the readings. Moreover, CGM systems provide alarms for low or high glucose and for rapid glucose changes, while Flash does not routinely provide alarms. This is particularly relevant when patients have impaired or lost hypoglycaemia awareness. CGM systems are costlier compared to Flash, which has contributed to the wider adoption of FSL. Several Bluetooth adjuncts have been introduced to market for FSL. These devices attach to Libre sensor and connect to the user's mobile phone via Bluetooth. This enables continuous and real-time feed of glucose readings from the sensor to patient's mobile phone, which enables a wide range of customizable alarms for high and low glucose levels and for rapid glucose changes. This setup also enables calibration of Libre sensor with capillary glucose which, anecdotally, has been reported to improve sensor accuracy. None of these adjuncts have been validated clinically. FSL with Bluetooth adjunct such as MiaoMiao remain cheaper than current CGM options and could be more accessible in some countries than CGM. However, without robust evidence to support effectiveness and safety of such setup it is not possible to recommend this. The Objective of this study is to determine whether FSL with Bluetooth Adjunct is superior to FSL alone in accuracy and reduction of hypoglycaemia burden.
The iLet is a closed-loop delivery system that can be used in insulin-only, bihormonal, or glucagon-only configurations. Previous studies have utilized a phone-based bionic pancreas. The iLet consists of a touchscreen-enabled, menu-driven user interface and an onboard microprocessor that provides a comprehensive and standalone platform, which allows the iLet to operate independently of smartphones or other devices and without the need for internet support during routine operation. This is a multicenter study of pediatric participants with type 1 diabetes, who will manage their diabetes with the iLet bionic pancreas compared to usual care.
BOL-DP-o-05 as an Add-On Treatment for Preservation of Beta-Cell Function in Subjects With Newly-Diagnosed Type 1 Diabetes Mellitus (T1DM)
Type 1 Diabetes (T1DM) is a common chronic illness in children which presents difficult and often stressful management concerns for parents. As children approach adolescence, this burden increases with the desire for independence and self-management. No tool exists that addresses in a user friendly, easy to access and socio-culturally appropriate way, the psychosocial needs of parents as they move through this transition. This program targets the parents to help them at the very point where this transition is occurring.
The most advanced configurations of the Artificial Pancreas (AP) have not yet been demonstrated to sufficiently maximize time in target glycemia. One limitation is the challenge of postprandial glycemic control, which currently requires ongoing patient engagement for accurate and detailed bolus dose estimation for meals. Sodium Glucose Linked Transporter 2 Inhibition (SGLT2i) provides an additional mechanism to attenuate post-prandial glycemic excursion, and may represent a strategy that could further alleviate carbohydrate counting burden and improve the performance of AP configurations. This trial aims to compare - using a randomized, masked placebo-controlled, crossover, multicenter design - the efficacy of the SGLT2i empagliflozin 25 mg oral per day each in the setting of single-hormone automated AP and conventional insulin pump therapy on the proportion of time spent in target and in hypoglycemia each during a 4-week day-and-night period. The pilot trial aims to enroll 28 adult patients with type 1 diabetes (T1D) across 2 research sites (one in Toronto and one in Montreal) and includes a 2- week therapy optimization run-in period, 4-weeks for each of the two AP intervention arms, and a 1- week washout in between the pharmacological intervention sequences. Glucose levels will be measured by continuous glucose monitoring (G5, Dexcom Inc.). Insulin will be infused using a subcutaneous infusion pump (t-slim, Tandem Diabetes Care) and communication between pumps and the algorithm will be implemented using Android Smartphone devices and Bluetooth technology communication.
This study is examining whether the Klue app is effective in detecting missed or late meal boluses in patients with Type 1 diabetes. The app is programmed onto an Apple Watch and will detect potential missed boluses from hand motion. It will send text alerts to the user asking if they have bolused. This is a pilot study and will assess whether there is a change in the number of missed meal boluses in the two weeks prior to each visit. If the findings are significant, this software can be integrated in future closed-loop algorithms for automatic insulin delivery.
In type 1 diabetes (T1DM), automated insulin delivery (AID) systems such as the hybrid closed loop artificial pancreas (HCL AP) combine the use of an insulin pump, continuous blood sugar monitor, and control algorithm to adjust background insulin delivery to improve time in target blood sugar range. Systems such as the predictive low glucose suspend system (PLGS) pause insulin delivery to try and reduce low blood sugars. We aim to complete a pilot study involving recruitment of youth ages 7 to 18 years from the following groups with type 1 diabetes: control participants consisting of youth on either multiple daily insulin injections or conventional insulin pump therapy that plan to continue with their current treatment modality, youth being transitioned to the HCL AP system, and youth being transitioned to the PLGS system. Individuals will be recruited into each of the aforementioned study groups based on their own expressed desire to either continue on MDI/standard insulin pump therapy or transition to either the HCL AP or PLGS systems. The decision to either continue with current therapy or transition therapy will remain entirely up to the participant and their family and will be based on personal preference and insurance coverage for that individual. We will not be randomizing the participants to any given treatment group during this study but rather will be recruiting based on the participant's decision. We would like to complete a physical exam with pubertal staging, collect blood and urine samples to evaluate cardiometabolic and renal markers, and complete a DXA scan to evaluate total lean and fat mass. After 3-6 months of either continuation of current treatment with either multiple daily insulin injections or conventional insulin pump therapy or transitioning to the HCL AP or PLGS systems, we would like to repeat the previously described blood, urine, and imaging tests for comparison. We are interested in examining the impact of the HCL AP and PLGS systems on maintaining blood sugars in target range, insulin sensitivity, and markers of cardiometabolic and renal function. We hypothesize that pauses in insulin delivery, as seen in the setting of automated insulin delivery systems, will result in improvements in insulin sensitivity, cardiometabolic markers, and renal function markers.
A randomized controlled clinical trial will be conducted in KasrELAiny hospitals, Cairo University and Beni-Suef University Hospital, including 80 uncontrolled diabetic pregnant women (type I) in the 3rd trimester (28-32 weeks of pregnancy) divided equally into study group and control group, to compare the usage of both metformin and insulin instead of using insulin alone. Group assignment will be randomized by computer program.
Aims: To profile the oral microbiome of children with type 1 diabetes mellitus, and to compare it to healthy children while taking into account other aspects of the oral environment. Research: exploring the differences between oral microflora of children with type 1 diabetes mellitus and control healthy children using salivary microbiome. The investigators will furthermore intend to analyze the differences of salivary flow rate, pH, glucose, calcium, inorganic phosphate and urea between the two groups.
Over 1.25 million Americans have Type 1 Diabetes (T1D), increasing risk for early death from cardiovascular disease (CVD). Despite advances in glycemic and blood pressure control, a child diagnosed with T1D is expected to live up to 17 years less than non-diabetic peers. The strongest risk factor for CVD and mortality in T1D is diabetic kidney disease (DKD). Current treatments, such as control of hyperglycemia and hypertension, are beneficial, but only partially protect against DKD. This limited progress may relate to a narrow focus on clinical manifestations of disease, rather than on the initial metabolic derangements underlying the initiation of DKD. Renal hypoxia, stemming from a potential metabolic mismatch between increased renal energy expenditure and impaired substrate utilization, is increasingly proposed as a unifying early pathway in the development of DKD. T1D is impacted by several mechanisms which increase renal adenosine triphosphate (ATP) consumption and decrease ATP generation. Caffeine, a methylxanthine, is known to alter kidney function by several mechanisms including natriuresis, hemodynamics and renin-angiotensin-aldosterone system. In contrast, to other natriuretic agents, caffeine is thought to fully inhibit the local tubuloglomerular feedback (TGF) response to increased distal sodium delivery. This observation has broad-ranging implications as caffeine can reduce renal oxygen (O2) consumption without impairing effective renal plasma flow (ERPF) and glomerular filtration rate (GFR). There are also data suggesting that chemicals in coffee besides caffeine may provide important cardio-renal protection. Yet, there are no data examining the impact of coffee-induced natriuresis on intrarenal hemodynamic function and renal energetics in youth-onset T1D. Our overarching hypothesis in the proposed pilot and feasibility trial is that coffee drinking improves renal oxygenation by reducing renal O2 consumption without impairing GFR and ERPF. To address these hypotheses, we will measure GFR, ERPF, renal perfusion and oxygenation in response to 7 days of cold brew coffee (one Starbucks® Cold brew 325ml bottle daily [205mg caffeine]) in an open-label pilot and feasibility trial in 10 adolescents with T1D already enrolled in the CASPER Study (PI: Bjornstad).
