Intraperitoneal vs Subcutaneous Insulin Administration in Type 1 Diabetes Mellitus
Type 1 Diabetes MellitusAlmost all patients with type 1 diabetes mellitus (T1DM) need insulin treatment permanently. For selected patients who are unable to achieve glycaemic targets with subcutaneous (SC) insulin treatment, continuous intraperitoneal (IP) insulin infusion is an third-line alternative. Previous studies demonstrate that continuous intraperitoneal insulin infusion (CIPII) using an implantable pump device improves glycaemic control and quality of life in patients with 'brittle' T1DM. Nevertheless, literature comparing IP and SC insulin treatment is scarce. The primary objective of this study is to compare the effects of IP insulin delivery to SC insulin delivery.The null hypothesis (H0) of the current study holds inferiority of CIPII compared to SC insulin regarding long-term glycaemic control. The alternative hypothesis (H1) is the inverse: CIPII is non-inferior to SC insulin. In summary, H0: CIPII is inferior to the SC insulin treatment H1: CIPII is not inferior to SC insulin treatment This is an investigator initiated, open label and prospective matched-control study with a non-inferiority design. The trial duration is 36 weeks and is conducted in a single-centre (Isala Clinics, Zwolle). If non-inferiority is established superiority analyses are performed.
Development of an Advisory System for Glycemic Control During the Menstrual Cycle in Patient With...
Type 1 Diabetes MellitusThis overall research goal will be to develop a mobile-based module to improve glycemic control during the menstrual cycle in women with Type 1 diabetes mellitus (T1DM). This module will run on an Android Operating System (OS) and will be available as: (i) a stand-alone application and (ii) an important additional component to a larger system, the Diabetes Assistant (DiAs) - a mobile-based medical platform for diabetes applications. This proposal aims to build one such application or module targeting the improvement of diabetes control in younger women who experience glucose variation related to their menstrual cycle.
Breakfast Nutrition and Inpatient Glycemia
DiabetesType 14 moreA standard hospital meal often contains a high percentage of carbohydrates (CHO), which may not be ideal for patients with diabetes. This concern is particularly pertinent to the breakfast meal, which often contains mainly CHO. Clinical observations suggested that such diets elevate pre-lunch blood glucose (BG) values. The study team compared standard hospital "no concentrated sweets (NCS)" breakfast meals with more balanced meals. The study team hypothesized that a balanced breakfast would improve pre-lunch BG values. This 8-week pilot study was conducted at Duke Hospital on two non-ICU cardiology wards. Ward A consisted mainly of patients with a primary diagnosis of coronary artery disease (CAD). Ward B consisted mainly of patients with a primary diagnosis of congestive heart failure (CHF). The intervention breakfast menu included 5 choices containing 40-45g of CHO. All patients on Ward A (with and without diabetes) were given the intervention breakfast for the first 4 weeks of the study, while those on Ward B received standard menus (60-75g CHO in NCS meals). After 4 weeks, the standard and intervention wards were switched. Data were collected only on patients with diabetes who were able to consume meals.
Overnight Closed Loop Study in U.S.
Type 1 DiabetesThis is a multicenter feasibility study. Up to 85 subjects will be enrolled in the study. The goal of the study is to demonstrate that the Hybrid Closed Loop (HCL) System is safe to be used in an even larger study outside of hospital.

Proof of Concept - Identification of Patient-specific Parameters for Bolus Calculators for Type...
Type1 Diabetes MellitusThe adoption of bolus calculators has been limited by the slow speed of the current trial and error approach. The goal of this project is to automate the determination of patient specific insulin pump parameters based on current automatic electronic logbooks of glucose measurements, carbohydrate intake, and insulin usage, by means of a mathematical model. More specifically, the investigators are interested in computing the carbohydrate to insulin ratio (CIR) and insulin sensitivity factor (ISF), which are the main parameters of bolus calculators. The present study is a proof-of-concept, open label, single arm clinical trial to validate the new method and refine both the mathematical model and the numerical techniques in well-regulated and disciplined type 1 diabetic subject. The study is a "trial" of the selected underlying mathematical model and the associated algorithms to simulate the glucose values of a patient with uncertain meal-data.
ANAIS, a Spanish Version of the DAFNE Programme
Diabetes MellitusType 1ANAIS is a therapeutic education programme for type 1 diabetes based on a flexible insulin regime adjusted to the patient's food intake. Participants are randomised in two groups, to attend the training course immediately (immediate ANAIS) or a year later (delayed ANAIS). The main outcome was HbA1c at one year.
CHO-loading Before and High Intermittent CHO-intake During Physical Exercise in T1D
Diabetes MellitusType 1Prolonged physical exercise (PE) is a challenge in type 1 diabetes with an increased incidence of both hypoglycemia and hyperglycemia. The purpose was to evaluate the impact of two consecutive days of carbohydrate (CHO) loading, followed by high intermittent CHO-intake during prolonged PE, facilitated by a proactive use of Real-Time Continuous Glucose Monitoring (rtCGM), on glucose control in individuals with type 1 diabetes. Ten physically active individuals with type 1 diabetes were invited to participate in a 3-day long sports camp with the objective to evaluate CHO-loading and high intermittent CHO-intake during prolonged PE. 1.5 months later the same procedure was evaluated during a 90 km cross-country skiing race. Participants were instructed to act proactively using rtCGM with predictive alerts set for high and low glucose values to maintain sensor glucose values within target range, defined as 72-180 mg/dl (4-10 mmol/l).
Longitudinal Observation of Insulin Requirements and Sensor Use in Pregnancy
Type 1 Diabetes MellitusPregnancy in DiabeticsThe overall goal of this study is to enroll pregnant women with type 1 diabetes and follow their glycemic outcomes prospectively throughout pregnancy and into the post-partum period. The investigators anticipate that when compared to subjects using an Artificial pancreas system (AP) as part of a future protocol, this comparator group of subjects undergoing usual care will exhibit less time in target continuous glucose monitoring (CGM) glucose range defined as 63-140 mg/dL and an increased duration of hypoglycemia with CGM glucose <63 mg/dL.
Group Education Curriculum for Older Teens With Type 1 Diabetes
Type 1 Diabetes MellitusSMART T1D is a research study that offers interactive diabetes education for teens with type 1 diabetes in peer groups led by diabetes nurse educators. Participants in the study will be randomly assigned to either receive three of the group sessions in addition to their routine clinic care or to receive their usual diabetes clinic care.
