Objective <p>Impaired awareness of hypoglycemia (IAH) in type 1 diabetes (T1D) is a major risk factor for severe hypoglycemia (SH), and is associated with atypical responses to hypoglycemia in brain regions involved in arousal, decision-making and memory. Whether restoration of hypoglycemia awareness alters these responses is unknown. We sought to investigate the impact of awareness restoration on brain responses to hypoglycemia.</p> <p> </p> <p>Research Design and Methods</p> <p>Twelve T1D IAH adults underwent pseudo-continuous arterial spin labelling functional MRI during a hypoglycemic clamp (5mmol/L-2.6mmol/L), before and after a hypoglycemia avoidance program of structured education (Dose Adjustment for Normal Eating, DAFNE), specialist support and sensor-augmented pump therapy (Medtronic Minimed™ 640G). Hypoglycemic cerebral blood flow (CBF) responses were compared pre- and post-intervention using predefined region of interest analysis of the thalamus, anterior cingulate cortex (ACC), orbitofrontal cortex (OFC) and hippocampus.</p> <p> </p> <p>Results</p> <p>Post-intervention, Gold and Clarke scores fell (6.0±1.0 to 4.0±1.6, p=0.0002; 5.7±1.7 to 3.4±1.8, p=0.0008), SH rates reduced (1.5±2 to 0.3±0.5 episodes per year, p=0.03), hypoglycemic symptom scores increased (18.8±6.3 to 27.3±12.7, p=0.02), epinephrine responses did not change (p=0.2). Post-intervention, hypoglycemia induced greater increases in ACC CBF (p=0.01, peak voxel coordinates [6,40,-2]), while thalamic and OFC activity did not change.</p> <p> </p> <p>Conclusions</p> <p>Increased blood flow is seen within brain pathways involved in internal self-awareness and decision-making (ACC) after restoration of hypoglycemia awareness, suggesting partial recovery of brain responses lost in IAH. Resistance of frontothalamic networks, involved in arousal and emotion processing, may explain why not all IAH individuals achieve awareness restoration with education and technology alone. </p>

Hypoglycaemia Awareness

IntroductionSevere hypoglycaemia (SH), when blood glucose falls too low to support brain function, is the most feared acute complication of insulin therapy for type 1 diabetes mellitus (T1DM). 10% of people with T1DM contribute nearly 70% of all episodes, with impaired awareness of hypoglycaemia (IAH) a major risk factor. People with IAH may be refractory to conventional approaches to reduce SH, with evidence for cognitive barriers to hypoglycaemia avoidance. This paper describes the protocol for the Hypoglycaemia Awareness Restoration Programme for People with Type 1 Diabetes and Problematic Hypoglycaemia Persisting Despite Optimised Self-care (HARPdoc) study, a trial to assess the impact on hypoglycaemia experience of a novel intervention that addresses cognitive barriers to hypoglycaemia avoidance, compared with an existing control intervention, recommended by the National Institute of Health and Care Excellence.Methods and analysisA randomised parallel two-arm trial of two group therapies: HARPdoc versus Blood Glucose Awareness Training, among 96 adults with T1DM and problematic hypoglycaemia, despite attendance at education with or without technology use, in four centres providing specialist T1DM services. The primary outcome will be the SH rate at 12 and/or 24 months after randomisation to either course. Secondary outcomes include rates of SH requiring parenteral therapy, involving unconsciousness or needing emergency services; hypoglycaemia awareness status, overall diabetes control and quality of life measures. An implementation study to evaluate how the interventions are delivered and how implementation impacts on clinical effectiveness is planned as a parallel study, with its own protocol.Ethics and disseminationThe protocol was approved by the London Dulwich Research Ethics Committee, the Health Research Authority, National Health Service R&D and the Institutional Review Board of the Joslin Diabetes Center in the USA. Study findings will be disseminated to study participants and through peer-reviewed publications and conference presentations, including user groups.Trial registration numberNCY02940873; Pre-results.

The Impact

Diabetes – a disease in which the effect of the treatment substantially depends on the patient. Known a study showed that the use of glucometers with the technology of three-color display of test results facilitates self-monitoring of blood sugar and leads to a decrease in glycated hemoglobin (HbAlc). Purpose of the study: to modeling the impact of using of a glucometer with a color-coded display on the clinical outcomes of diabetes mellitus and calculating, the potential economic benefits of reducing the hospitalization rate of patients with diabetes. Material and methods. Based on data from two studies (O. Schnell et al. and M. Baxter et al.) simulation of the reduction in the number of complications with the use of a glucometer with a color indication. In a study by O. Schnell et al. a decrease of HbA1c by 0.69 percent is shown when using the considered type of glucometers, which was the basis of the model. Results. In the model, the use of a glucometer with a color-coded display for type 1 diabetes led to a decrease in the total number of complications by 9.2 thousand over 5 years per a cohort of 40 thousand patients with different initial levels of HbA1c. In a cohort of 40 thousand patients with type 2 diabetes, the simulated number of prevented complications was 1.7 thousand over 5 years. When extrapolating these data to all patients with diabetes included in the federal register of diabetes mellitus (FRD), the number of prevented complications was 55.4 thousand cases for type 1 diabetes and 67.1 thousand cases for type 2 diabetes. The possible economic effect from the use of the device by all patients with a diagnosis of diabetes, which are included in the FRD, estimated at 1.5 billion rubles for a cohort of patients with type 1 diabetes and 5.3 billion rubles for patients with type 2 diabetes. Conclusion. Improving the effectiveness of self-monitoring, which is the result of the use of glucometers with color indicators, can potentially significantly reduce the incidence of complications in diabetes and thereby provide significant economic benefits to society.

AbstractObjectivesPaucity of data from India on care of children with Type 1 diabetes in schools. Aims: To study assess the knowledge, attitude, practices and fear of Type 1 diabetes in school teachers and to assess the impact of an educational model on the fear of teachers and care of children in Type 1 DM at school hours.MethodsA community based study, involving school teachers and the intervention being educating them about diabetes conducted. Data pertaining to basic demography, attitude of teachers towards diabetic children, Hypoglycemia fear factor survey- parent version with worries domain and preparedness of school was collected. An education program was conducted on diabetes care in children. Immediately and after three months, the proforma details and HFSP-W scores reassessed.ResultsForty two teachers (mean age: 38.7±5.4; M:F ratio 2:40) participated in the study. Post intervention, a higher willingness to have the diabetic child in class (100 vs. 57.1%; p>0.05), better support in daily care (100 vs. 92%; p>0.05), participation in sports activities (100 vs. 7.1%; p<0.05) observed. HFSP-W scores were 38.8±4.5 (pre-intervention), 22.5±4.3 (immediate post intervention) and 29.5±3.2 (at 3months) (p<0.05). To study the determinants of improvement in HFSP-W a regression analysis was performed: presence of glucometer the most likely determining factor (T=1.999, p=0.05).ConclusionThere is a significant element of fear in the minds of teachers towards hypoglycemia which improves with a structured education program.

The Impact

Background: In the management of type 1 diabetes (T1D), systematic and random errors in carb-counting can have an adverse effect on glycemic control. In this study, we performed an in silico trial aiming at quantifying the impact of different levels of carb-counting error on glycemic control. Methods: The T1D patient decision simulator was used to simulate 7-day glycemic profiles of 100 adults using open-loop therapy. The simulation was repeated for different values of systematic and random carb-counting errors, generated with Gaussian distribution varying the error mean from -10% to +10% and standard deviation (SD) from 0% to 50%. The effect of the error was evaluated by computing the difference of time inside (∆TIR), above (∆TAR) and below (∆TBR) the target glycemic range (70-180mg/dl) compared to the reference case, that is, absence of error. Finally, 3 linear regression models were developed to mathematically describe how error mean and SD variations result in ∆TIR, ∆TAR, and ∆TBR changes. Results: Random errors globally deteriorate the glycemic control; systematic underestimations lead to, on average, up to 5.2% more TAR than the reference case, while systematic overestimation results in up to 0.8% more TBR. The different time in range metrics were linearly related with error mean and SD ( R2>0.95), with slopes of [Formula: see text], [Formula: see text] for ∆TIR, [Formula: see text], [Formula: see text] for ∆TAR, and [Formula: see text], [Formula: see text] for ∆TBR. Conclusions: The quantification of carb-counting error impact performed in this work may be useful understanding causes of glycemic variability and the impact of possible therapy adjustments or behavior changes in different glucose metrics.

Abstract Objectives Our study aims to assess the impact of lockdown during the coronavirus disease 2019 pandemic on glycemic control and psychological well-being in youths with type 1 diabetes. Methods We compared glycemic metrics during lockdown with the same period of 2019. The psychological impact was evaluated with the Test of Anxiety and Depression. Results We analyzed metrics of 117 adolescents (87% on Multiple Daily Injections and 100% were flash glucose monitoring/continuous glucose monitoring users). During the lockdown, we observed an increase of the percentage of time in range (TIR) (p<0.001), with a significant reduction of time in moderate (p=0.002), and severe hypoglycemia (p=0.001), as well as the percentage of time in hyperglycemia (p<0.001). Glucose variability did not differ (p=0.863). The glucose management indicator was lower (p=0.001). 7% of youths reached the threshold-score (≥115) for anxiety and 16% for depression. A higher score was associated with lower TIR [p=0.028, p=0.012]. Conclusions Glycemic control improved during the first lockdown period with respect to the previous year. Symptoms of depression and anxiety were associated with worse glycemic control; future researches are necessary to establish if this improvement is transient and if psychological difficulties will increase during the prolonged pandemic situation.
