Filter by:The MD-Logic Automated Insulin Delivery System is intended for patients with type 1 diabetes mellitus for subcutaneous infusion of insulin and the continuous measurement of interstitial glucose to aid in the management of their diabetes. The product automatically adjusts basal insulin delivery and delivers correction boluses in response to real-time glucose measurements by CGM to maintain blood glucose within the desired range, to improve metabolic control without increasing the risk of hypoglycemia. The proposed study is an open-label, two-center, randomized, cross-over study to evaluate the safety and efficacy of night closed-loop control using the MD-Logic automated insulin delivery system compared to sensor augmented pump therapy in poorly controlled patients with type 1 diabetes at home The objective of this pilot study is to evaluate the safety and efficacy of 4 weeks glucose control using the MD-Logic System in individuals with poorly controlled type 1 diabetes at patient's home
The purpose of this pilot study was to evaluate the effect of D-chiro-Inositol (DCI) oral supplementation in addiction to folic acid compared to folic acid alone on glycaemic control as assessed by HbA1c in overweight or obese T1D patients undergoing intensive insulin therapy. A 24 weeks, prospective, randomized control trial was carried out in T1D patients, aged 17-50 years (13 males, 13 females), with disease duration > 1 year and BMI >25, attending as outpatients the Endocrinology and Diabetes Unit of University Campus Bio-Medico in Rome
The main objective of this study is to determine whether day and night closed-loop insulin delivery for 4 weeks under free living conditions is superior to usual insulin pump therapy in adults with type 1 diabetes and HbA1C<7.5%. This is an open-label, multi center, randomized, crossover design study, involving a 2-4 week run-in period, followed by two 4 weeks study periods during which glucose levels will be controlled either by an automated day- and night closed-loop system or by subjects usual insulin pump therapy in random order. A total of up to 34 adults (aiming for 24 completed subjects) aged 18 years and older with T1D on insulin pump therapy and HbA1C<7.5% will be recruited through diabetes clinics and other established methods in participating centers. Subjects will receive appropriate training in the safe use of closed-loop insulin delivery system. Subjects will have regular contact with the study team during the home study phase including 24/7 telephone support. The primary outcome is time spent in target range between 3.9 and 10.0 mmol/L as recorded by CGM during home stay. Secondary outcomes are time spent with glucose levels above and below target, as recorded by CGM, and other CGM-based metrics.
Objective: to gain experience in children and younger adolescents with in-home use of an algorithm that will dose insulin to minimize projected hyperglycemia overnight in addition to suspending the pump if hypoglycemia is projected overnight and to obtain feasibility, safety, and initial efficacy data Study Design: randomized controlled trial, with randomization on a night level within subject Patient Population: Youth 6.0 - <15 years old with type 1 diabetes treated with daily insulin therapy for at least one year and an insulin infusion pump for at least 6 months who have HbA1c < 10.0%. Sample Size: 30 subjects Study Duration and Visit Schedule: duration approximately 3 months, with preliminary run-in activities followed by up to 90 days spent in clinical trial phase of study; clinic visits at enrollment, following CGM and system assessment run-in phases, at start of clinical trial phase, at 21-day point of clinical trial phase, and after 42 nights of successful system use Major Efficacy Outcomes: - Primary: time in range (70-180 mg/dl, 3.9-10.0 mmol/L) overnight. - Secondary: time spent in hypoglycemia (<70 mg/dl, 3.9 mmol/L) and time spent in hyperglycemia (>180 mg/dl, 10.0 mmol/L) overnight. Major Safety Outcomes: CGM measures of hypo- and hyperglycemia, including morning blood glucose and mean overnight sensor glucose; adverse events including severe hypoglycemia and diabetic ketoacidosis
This is a single center, single-blind randomized cross over design trial that will compare the impact of intra-nasal naloxone vs. intra-nasal saline administration during experimental hypoglycemia on day one on responses to experimental hypoglycemia on day two. Investigators intend to enroll 18 individuals to obtain the complete data sets from 15 participants. Expected duration of subject participation is 10-12 weeks. This study will consist of two 2-day intervention visits separated by approximately 8 weeks.
This research study is designed to look at differences in responsiveness to the subcutaneous injection of a standardized dose of rapid-acting insulin analog and blood glucose variability during different phases of the menstrual cycle in females with type 1 diabetes (T1D).
The purpose of this study is to collect data on the feasibility of the HLCL system in a camp setting.
Objective: To investigate whether visceral adipose tissue (VAT) and its adipokines contribute to early signs of cardiovascular disease, meaning coronary artery calcifications (CAC) and diastolic dysfunction in type 1 diabetes (T1DM). Research Design & Methods: A cross-sectional study of T1DM patients without a history of cardiovascular disease. CAC and VAT are measured using a CT scan. CAC is scored using the Agatston method. Echocardiography is performed to assess contractile abnormalities. Serum levels of adipocytokines (adiponectin, leptin, IL-6 and TNF-a) are measured using ELISA assays.
In people with type I diabetes, the insulin producing cells in the pancreas have been destroyed. Presently one can only evaluate the function of the graft through laboratory tests, blood sugars and the insulin requirements. The mass of the insulin producing cells and their location are not known. The possibility to study the mass of insulin producing cells is of importance when developing new treatment regimes, in order to evaluate their efficacy on this parameter. The researchers in this study are aiming to develop methods to measure the mass of insulin producing cells. A method (positron emission tomography, PET) previously used for the diagnosis of tumors of insulin producing cells may also be used to measure the amount of insulin producing cells in patients with type I diabetes. They plan to evaluate participants with type 1 diabetes that have undergone islet transplantation, to evaluate if PET can be used to measure the beta cell mass after islet transplantation.
The risk of hypoglycemia in individuals with type 1 diabetes increases considerably during exercise. As a result, many patients with type 1 diabetes experience fear of and reluctance to pursue physical activity, in order to avoid the discomforting symptoms associated with hypoglycemia. The bi-hormonal artificial pancreas, a device used for automatic delivery of insulin and glucagon subcutaneously to subjects with type 1 diabetes, is paving the way to revolutionize the management of this disease. The investigator's group has recently completed a study of the bi-hormonal artificial pancreas system during exercise, suggesting reduced hypoglycemia around the exercise period. In order to prepare for a future home study, the ability to detect, grade, and classify physical activity so as to appropriately adjust system parameters is vital in helping to prevent exercise induced hypoglycemia in the home setting. This study is designed to collect 3-axis accelerometry data and heart rate data during a variety of different home activities, as well as during formal exercise in both healthy subjects and subjects with type 1 diabetes. Additionally, the investigators will observe the change in glucose levels before and after exercise in subjects with type 1 diabetes.
