Self-Management in Young Adults With Type 1 Diabetes

Type 1 Diabetes

Type 1 Diabetes (T1D) affects 1.6 million Americans, and only 14% of young adults age 18-25 years achieve glycemic targets (glycosylated hemoglobin A1C <7.0%). Achieving glycemic targets is associated with reduced risk for both micro-and macrovascular complications, better neurocognitive function, and better diabetes quality of life. In lab studies, sleep deprivation led to impaired glucose tolerance and insulin sensitivity in adults without chronic condition and in one study of adults with T1D. Extending sleep in natural environments contributes to improved insulin sensitivity and glucose levels, neurocognition, and psychological symptoms in young adults without chronic conditions. Modifiable dimensions of sleep health (appropriate sleep duration, stability, and timing) are associated with better glycemic control in adults with T1D. Therefore, improving sleep duration, stability, and timing may be potential therapeutic targets to improve glucoregulation and clinical outcomes (diabetes self-management, neurocognitive function, and symptoms) in this high-risk population. The overall objective is to test and compare the effects of a cognitive-behavioral sleep self-management intervention (sleep extension and consistency in sleep timing) compared to an attention control condition (habitual sleep duration + diabetes self-management education) on improving sleep duration, stability, and timing, and glycemia (glycemic control and glucose variability) in short-sleeping young adults with T1D in a pilot randomized controlled trial.

Probiotics in Newly Diagnosed T1D

Type 1 DiabetesType1diabetes1 more

The investigators aim to further the understanding of environmental factors that underlie the development of Type 1 diabetes (T1D) and the post-onset disease trajectory. Dysbiosis, defined as alterations in intestinal microbiota composition and function, has been hypothesized to increase the risk of developing T1D in those with genetic susceptibility. Dysbiosis may result from modern dietary habits, such as broad consumption of the highly processed Western Diet, or by widespread use of antibiotics. Here, the investigators propose to examine the impact of dysbiosis on the endogenous innate inflammatory state that potentiates T1D progression. The investigators hypothesize that probiotic-induced alterations in the intestinal microbiota may favorably alter the post-onset disease state.

Cardiovascular Effects of Rapidly Declining Plasma Glucose in Patients With Type 1 Diabetes

Type 1 Diabetes

Type 1 diabetes (T1D) is an autoimmune metabolic disease characterised by impaired lack of endogenous insulin causing elevated plasma glucose levels and increased risk of microvascular and macrovascular complications. With respect to the cardiovascular system, patients with T1D have an up to 10-fold increased risk of sudden cardiac death compared to healthy individuals. Furthermore, diabetes constitutes a hypercoagulable state, which to some extent may explain why cardiovascular disease still is a major cause of mortality in patients with T1D. Due to treatment with exogenously delivered insulin, glycaemic variability with intra-day and inter-day plasma glucose concentrations fluctuating between high levels (peaks) and low levels (nadirs), are inevitable in patients with T1D. A potentially important factor in development of cardiovascular disease, associated with glycaemic variability, is the rate of increase and/or decline of plasma glucose. The aim of this study is to test the hypothesis that a rapid plasma glucose decline from a hyperglycaemic level to an euglycaemic level can induce changes in QT-interval and blood coagulation in a proarrhythmogenic and prothrombotic way. Twenty patients with T1D with a 1:1 distribution with chronic hyperglycaemia (HbA1C ≥63 mmol/mol) and with well-controlled diabetes (HbA1C ≤53 mmol/mol) will be recruited for a crossover study including two test days (protocols), P-rapid, a combined hyperglycaemic and euglycaemic clamp with rapidly declining plasma glucose and P-slow, a combined hyperglycaemic and euglycaemic clamp with slowly declining plasma glucose. Patients will be randomised 1:1 to start with P-rapid or P-slow. The cardiovascular effects will be investigated using Holter-ECG, Thrombelastography, Echocardiography and blood sampling. Given that cardiovascular disease is a major cause of death in patients with T1D and that patients with diabetes may be more susceptible for cardiac arrhythmias and thrombotic events compared to healthy individuals, it is important to identify cardiovascular risk factors related to acute changes in plasma glucose in order to improve prevention strategies and therapy.

Advancing Understanding of Transportation Options

Diabetic RetinopathyMacular Degeneration30 more

This Stage II randomized, controlled, longitudinal trial seeks to assess the acceptability, feasibility, and effects of a driving decision aid use among geriatric patients and providers. This multi-site trial will (1) test the driving decision aid (DDA) in improving decision making and quality (knowledge, decision conflict, values concordance and behavior intent); and (2) determine its effects on specific subpopulations of older drivers (stratified for cognitive function, decisional capacity, and attitudinally readiness for a mobility transition). The overarching hypotheses are that the DDA will help older adults make high-quality decisions, which will mitigate the negative psychosocial impacts of driving reduction, and that optimal DDA use will target certain populations and settings.

Diabetes MellitusType 1

Study population : 90 Participants. 60 with T1DM , and 30 healthy controls. T1DM patients will be recruited by research publication in diabetes mellitus forums. Baseline visit: informed consent signing. Medical history data, vital signs, physical exam and neurocognitive testing. Capillary glucose prior to testing > 70 mg/dl. Session 2 - combined simultaneous EEG , continuous glucose monitor system (CGMS) assessment, neurocognitive testing, and sleep quality assessment. Participants will be hospitalized for 30 hours in the continuous-EEG unit at the Pediatric Neurology Department, Assaf-Harofeh Medical Center. Continuous simultaneous EEG and CGMS monitoring, and two separate sessions of neurocognitive assessments at glucose > 240 mg/dl and at glucose < 180 mg/dl, respectively. Neurocognitive assessment will be performed after lunch on day 1, and after lunch on day 2. Day 1, regular insulin dose before lunch, and a cognitive assessment which will be performed with glucose level > 70 mg/dl and below 180 mg/dl. On day 2, with no regular insulin dose before lunch and the same cognitive test will be performed with glucose level > 240 mg/dl During the 30 hours the participants will be connected to continuous EEG recording, sleep monitoring and CGMS. The study participants and research team will be blinded to the EEG and CGMS readings while recorded. Participants will be able to convey their daily activities in their room. They will have their regular diet and regular daily activities. Participants will measure at least 4 blood glucose measurements by prick tests, insulin management by multiple daily injections or pump therapy and meals. Healthy participants will measure twice daily as required for CGMS calibration. The participants will stay connected to the CGMS for additional 4 days at their home setting for complete sleep quality assessment by sleep diary and actigraph. The first night in hospital is to assess the association between actigraph and EEG and CGMS variability. The 4 nights at home are for assessment of CGMS, quality of life and actigraph readings. Control group (healthy) will perform only one session of neurocognitive studies on day 1, after lunch with no insulin injection and will be discharged after 24 hours, with the CGMS and actigraph

Comparison of Low, Moderate and High Carbohydrate Diet on Insulin Requirements and Metabolic Control...

Type1diabetes

The scientific basis for dietary recommendations in type 1 diabetes is almost lacking, with the current recommendations being based on type 2 diabetes studies. Therefore the overall purpose of this study is to improve the current evidence for dietary recommendations to people with type 1 diabetes. Study aim: To compare how a strictly low carbohydrate diet, a moderately low carbohydrate diet and a traditional diabetes diet (with higher amounts of carbohydrates) affect insulin requirements and metabolic control in individuals with type 1 diabetes. Carbohydrate intake is 50-60% of the total energy intake in the traditional diabetes diet, 30-40% in the moderately low carbohydrate diet and 15-20% in the strictly low carbohydrate diet with a minimum of 50 g carbohydrates/day. A diet with less than 50 g carbohydrates/day is usually called very low carbohydrate diet or ketogenic and will not be tested in this study. Those who wish to participate and meet the inclusion criteria (and none of the exclusion criteria) will be randomized to one of the three diets. The duration of the intervention is 6 months after which the participants will be able to choose their own diet for another 6 months. The main study visits are at baseline (screening and study start), 3, 6, 9, and 12 months. Shorter visits will be at 3 and 6 weeks. The participants will meet with a study nurse, dietitian and doctor. They will attend two carbohydrate counting courses before the start of the intervention in order to be able to match their insulin to the amount carbohydrates they eat. Participants will receive written materials about their diets with menus and recipes for better adherence to the diet. The primary endpoint is the change in insulin requirements within and between groups (for secondary endpoints please see relevant section). For assessing the different endpoints the participants will provide blood, urine and feces samples for lab analyses as well as register their insulin use, blood glucose, diet, physical activity and any blood ketones or hypoglycemia electronically or in written forms. Continuous/flash glucose monitoring (CGM/FGM) will be also used. Dietary assessment and adherence will be based on 3-4 day food diaries before every scheduled study visit.

Metabolic Adaptation to High-frequent Hypoglycaemia in Type 1 Diabetes

Type1diabetes

An experimental mechanistic study. The overall objective is to gain new knowledge about mechanisms involved in adaptation to recurrent hypoglycaemia in diabetes by investigating patients with type 1 diabetes and healthy controls. The knowledge to be obtained may feed into experimental hypoglycaemic clamp studies to further elucidate the effect of the adaptations during acute hypoglycaemia. Ultimately, it may lead to intervention studies aiming at the maintenance of functional capability during hypoglycaemia in patients with type 1 diabetes to reduce their risk of severe hypoglycaemia.
