Abstract
BACKGROUND Poorly controlled adolescents living with type 1 diabetes (T1D) and pump failure of insulin delivery leading to diabetic ketoacidosis (DKA) are still challenging in the western world. AIM To investigate the effect of a combination modality of long-acting insulin for basal coverage and a pump for boluses, on the incidence of DKA and glycemic parameters in pediatric and young adults with poorly controlled T1D. METHODS This multicenter, observational retrospective study included 55 patients (age range 3-25 years, 52.7% males) who were treated with the combination modality for a median of 18 months [(IQR)12,47], as part of their clinical care. Data were retrieved at initiation of the combined modality, after 6 months, and at last visit. RESULTS Cohort's median age at combination modality initiation was 14.5 years [IQR12.4,17.3], and its median HbA1c level was 9.2% [IQR 8.2,10.2]. The main reasons for combination modality initiation were: (a) concern about sustained hyperglycemia on current management in 41.8%, (b) previous DKA episodes in 30.8%, and (c) refusal to wear a pump continuously in 14.6%. The percent of patients experiencing DKA who used the modality till end decreased from 25.4 to 8.8%. The frequency of DKA events per patient month decreased after 6 months from 0.073 (min 0, max 0.5) to 0.020 (min 0, max 0.5), p = 0.01, and at end to 0.016 (min 0, max 0.25), p = 0.007. CONCLUSIONS The combination modality of once-daily long-acting insulin and pump for boluses is safe, feasible, and effective in preventing DKA among poorly controlled young people living with T1D, unable or un-willing to use advanced closed pumps.

Abstract
Background and Aims: Disordered eating behaviors (DEB) are more common among individuals with type 1 diabetes (T1D) compared to those without, and for insulin pump users may be associated with higher hemoglobin A1c (HbA1c). We investigated DEB risk factors among insulin pump-treated individuals with T1D and clinical characteristics of hybrid closed-loop (HCL) systems' users by DEB level. Methods: An observational, cross-sectional study of 167 insulin pump-treated individuals with T1D, 13-21 years of age. Data were obtained from patients' medical charts with additional self-reported questionnaires, including assessment of DEB. Results: DEB were found in 71 (42.5%) individuals, and positively associated with female sex (β = 2.98 [standard error (SE) = 1.31], P = 0.025), body mass index (BMI)-Z-score (β = 2.12 [SE = 0.64], P = 0.001), HbA1c (β = 1.40 [SE = 0.45], P = 0.02), and higher rate of pump discontinuation (β = 4.48 [SE = 1.99], P = 0.026). The use of HCL systems compared to insulin pumps was associated with higher BMI-Z-score (odds ratio [OR]: 3.46 [95% confidence interval, CI: 1.52-7.87], P = 0.003) and tendency to lower HbA1c level (OR: 0.44 [95% CI: 0.18-1.09], P = 0.078) among individuals without DEB, and with lower HbA1c level (OR: 0.29 [95% CI: 0.10-0.83], P = 0.022) and higher socioeconomic status (OR: 1.73 [95% CI: 1.09-2.74], P = 0.020) among individuals with DEB. Conclusions: DEB are common among individuals with T1D treated with insulin pumps and are associated with higher HbA1c levels. Among T1D individuals with DEB, HCL system use is associated with lower HbA1c compared to insulin pump treatment. Our findings highlight the importance of regular screening for DEB and its risk factors to improve pump treatment and diabetes management. Moreover, individuals with DEB using HCL systems may benefit from reduced HbA1c levels.

Abstract
AIMS To assess the prevalence and disease-related risk factors for disordered eating behaviours among adolescents with type 1 diabetes and also to search for risk factors at disease diagnosis that can predict the development of disordered eating behaviours. METHODS A retrospective observational study of 291 adolescents aged 15-19 years with type 1 diabetes who completed the Diabetes Eating Problem Survey-Revised (DEPS-R) as is routine in our diabetes clinic. The prevalence of disordered eating behaviours and risk factors for their development was assessed. RESULTS In 84 (28.9%) adolescents, disordered eating behaviours were found. Disordered eating behaviours were positively associated with female sex (β = 3.01 [SE = 0.97], p = 0.002), higher BMI-Z score (β = 2.08 [SE = 0.49], p < 0.001), higher HbA1c (β = 0.19 [SE = 0.03], p < 0.001) and treatment with multiple daily injections of insulin (β = 2.19 [SE = 1.02], p = 0.032). At type 1 diabetes diagnosis, higher BMI-Z score (β = 1.54 [SE = 0.63], p = 0.016) for those diagnosed before age 13 years and increased weight gain at 3 months post-diagnosis (β = 0.88 [SE = 0.25], p = 0.001) in females diagnosed at age 13 years or older were found to be risk factors for disordered eating behaviours. CONCLUSIONS Disordered eating behaviours are common among adolescents with type 1 diabetes and are associated with various parameters, including BMI at diagnosis and the rate of weight gain at 3 months post-diagnosis in females. Our findings highlight the need for early preventive efforts for disordered eating behaviours and interventions to avoid late diabetes complications.

Abstract
OBJECTIVE Insulin pump discontinuation has mostly been studied in children and adolescents living with diabetes. We aimed to assess the rate of insulin pump continuation in a population of adult patients with diabetes, at 18 months after initiation, to determine the factors associated with pump discontinuation, and to develop a simple prediction model. METHODS This single-center, retrospective study included all adult patients with type 1 (T1D) or type 2 (T2D) diabetes, who started insulin pump treatment between January 2015 and June 2018. Exclusion criteria were pregnancy, short-term pregnancy plans, and insulin pump discontinuation within the previous six months. The probability of insulin pump continuation after 18 months was estimated using the Kaplan-Meier method. Factors associated with insulin pump discontinuation were studied using a Cox regression model and an exponentia model was built for prediction purposes. RESULTS The study included 315 patients. Mean age was 41 years; mean duration of diabetes was 16 years; 50% were men; 74% had T1D; mean HbA1c was 9.1% (76 mmol/mol). After 18 months, the rate of insulin pump continuation was 0.80 (95%CI: 0.76-0.85). By multivariate analysis, the occurrence of severe hypoglycemia in the previous year was associated with insulin pump discontinuation (HR 2.42; 95%CI 1.30-4.51) while other factors did not reach statistical significance. CONCLUSION Insulin pump discontinuation occurred in 20% of patients at 18 months after initiation and was mainly associated with a recent history of severe hypoglycemia. The type of diabetes and glycemic control at baseline were not associated with treatment discontinuation.

Abstract
Diabetes-related technology has undergone great advancement in recent years. These technological devices are more commonly utilized in the type 1 diabetes population, which requires insulin as the primary treatment modality. Available devices include insulin pumps, continuous glucose monitors, and hybrid systems referred to as automated insulin delivery systems or hybrid closed-loop systems, which combine those two devices along with software algorithms to achieve advanced therapeutic capabilities, including automatic modulation of insulin delivery based on sensor-derived glucose levels to minimize abnormal glucose trends. Use of diabetes technology is associated with significant positive health and psychosocial outcomes, yet utilization rates are generally lacking across both adult and pediatric type 1 diabetes populations in the United States and other countries. There are consistent themes in existing barriers to technology uptake reported by individuals with type 1 diabetes or parents of children with type 1 diabetes, including physical burdens associated with wearing the devices, concerns in navigating the technology and the devices’ abilities to meet user expectations, high cost, inadequate resources within the healthcare team to support device use, disparities in technology access, and psychosocial barriers. It is important to understand the common barriers to uptake of not only the automated insulin delivery systems but also their component devices (insulin pumps and continuous glucose monitors) to fully support individuals in utilizing these devices and optimizing health benefits. The purpose of this article is to summarize the current automated insulin delivery devices that are available for use in management of type 1 diabetes, review common barriers to uptake of those systems and their component devices, and provide expert opinion on existing and future solutions to identified barriers.

Abstract
PURPOSE Despite the prevalent use of insulin pump therapy worldwide, few studies have been conducted among young patients with type 1 diabetes (T1D) in Korea. We investigated the durability and effectiveness of insulin pump therapy among Korean pediatric and young adult patients with T1D. METHODS This study included 54 patients with T1D diagnosed at pediatric ages (range, 1.1-14.1 years) who initiated insulin pump therapy during 2016-2019 at Seoul National University Children's Hospital and Seoul National University Bundang Hospital. Clinical and biochemical data, including anthropometric measurements, insulin dose, and glycated hemoglobin (HbA1c) levels were obtained from T1D diagnosis to last follow-up. RESULTS Forty-four patients (81.5%) continued insulin pump therapy with a median pump use duration of 2.9 years (range, 0.2-3.5 years); 10 discontinued the therapy within 12 months (<1 month, n=6; 1-6 months, n=1; and 6-12 months, n=3) due to physical interferences or financial problems. Older age (≥10 years of age) and longer diabetes duration (≥2 years) at the initiation of pump therapy were associated with discontinuation (P<0.05 for both). For patients continuing pump therapy, HbA1c levels significantly decreased after 1 year of therapy (from 8.9% to 8.1%, P<0.001) without changes in the body mass index z-scores or insulin dose. Although 4 patients experienced diabetic ketoacidosis, all recovered without complications. CONCLUSION Insulin pump therapy was effective in improving glycemic control in T1D patients during 12 months of treatment. Early initiation of insulin pump therapy after T1D diagnosis was helpful for continuing therapy.

Abstract
BACKGROUND Advances in pump technology have increased the popularity of this treatment modality among patients with type 1 diabetes and recently also among patients with type 2 diabetes. AREAS OF UNCERTAINTY Four decades after the incorporation of the insulin pump in clinical use, questions regarding its efficacy, occurrence rate of short-term complications as hypoglycemia and diabetes ketoacidosis, timing of pump initiation, and selected populations for use remain unanswered. DATA SOURCES A review of the literature was performed using the PubMed database to identify all articles published up till December 2018, with the search terms including insulin pump therapy/continuous subcutaneous insulin delivery. The Cochrane database was searched for meta-analysis evaluating controlled randomized trials. Consensuses guidelines published by the International Society for Pediatric and Adolescent Diabetes, American Diabetes Association, and Advanced Technologies and Treatments for Diabetes year books were additionally reviewed for relevant cited articles. THERAPEUTIC ADVANCES Insulin pump therapy offers flexible management of diabetes. It enables adjustment of basal insulin to daily requirements and circadian needs, offers more precise treatment for meals and physical activity, and, when integrated with continuous glucose monitoring, allows glucose responsive insulin delivery. The ability to download and transmit data for analysis allow for treatment optimization. Newer pumps are simple to operate and increase user experience. Studies support the efficacy of pump therapy in improving glycemic control and reducing the occurrence of hypoglycemia without increasing episodes of diabetes ketoacidosis. They also improve quality of life. Recent evidence suggests a role for pump therapy in reducing microvascular and macrovascular diabetes-related complications. CONCLUSIONS Insulin pump therapy appears to be effective and safe in people with T1D regardless of age. Future advancements will include incorporation of closed loop and various decision support systems to aid and improve metabolic control and quality of life.

Abstract
The use of advanced technologies for diabetes management is on the rise among pediatric patients with type 1 diabetes (T1D). Continuous subcutaneous insulin infusion (CSII), continuous glucose monitoring, predictive low glucose suspend, hybrid closed-loop insulin delivery systems-all enable better diabetes management and glycemic control. However, when used by children, and especially very young children, specific aspects must be taken into consideration, including technical parameters, ease of use, parental stress, and satisfaction. The unique characteristics of T1D in children aged <6 years are reviewed and studies of the pros and cons of different technologies in this specific age group are presented. Addressing such issues when implementing advanced technologies among very young children with T1D will enable better diabetes management and will hopefully ease a tremendous burden of both children and families.

Abstract
BACKGROUND The risk of developing long-term complications of type 1 diabetes (T1D) is related to glycaemic control and is reduced by the use of intensive insulin treatment regimens: multiple daily injections (MDI) (≥ 4) and continuous subcutaneous insulin infusion (CSII). Despite a lack of evidence that the more expensive treatment with CSII is superior to MDI, both treatments are used widely within the NHS. OBJECTIVES (1) To compare glycaemic control during treatment with CSII and MDI and (2) to determine safety and cost-effectiveness of the treatment, and quality of life (QoL) of the patients. DESIGN A pragmatic, open-label randomised controlled trial with an internal pilot and 12-month follow-up with 1 : 1 web-based block randomisation stratified by age and centre. SETTING Fifteen diabetes clinics in hospitals in England and Wales. PARTICIPANTS Patients aged 7 months to 15 years. INTERVENTIONS Continuous subsutaneous insulin infusion or MDI initiated within 14 days of diagnosis of T1D. DATA SOURCES Data were collected at baseline and at 3, 6, 9 and 12 months using paper forms and were entered centrally. Data from glucometers and CSII were downloaded. The Health Utilities Index Mark 2 was completed at each visit and the Pediatric Quality of Life Inventory (PedsQL, diabetes module) was completed at 6 and 12 months. Costs were estimated from hospital patient administration system data. OUTCOMES The primary outcome was glycosylated haemoglobin (HbA1c) concentration at 12 months. The secondary outcomes were (1) HbA1c concentrations of < 48 mmol/mol, (2) severe hypoglycaemia, (3) diabetic ketoacidosis (DKA), (4) T1D- or treatment-related adverse events (AEs), (5) change in body mass index and height standard deviation score, (6) insulin requirements, (7) QoL and (8) partial remission rate. The economic outcome was the incremental cost per quality-adjusted life-year (QALY) gained. RESULTS A total of 293 participants, with a median age of 9.8 years (minimum 0.7 years, maximum 16 years), were randomised (CSII, n = 149; MDI, n = 144) between May 2011 and January 2015. Primary outcome data were available for 97% of participants (CSII, n = 143; MDI, n = 142). At 12 months, age-adjusted least mean squares HbA1c concentrations were comparable between groups: CSII, 60.9 mmol/mol [95% confidence interval (CI) 58.5 to 63.3 mmol/mol]; MDI, 58.5 mmol/mol (95% CI 56.1 to 60.9 mmol/mol); and the difference of CSII - MDI, 2.4 mmol/mol (95% CI -0.4 to 5.3 mmol/mol). For HbA1c concentrations of < 48 mmol/mol (CSII, 22/143 participants; MDI, 29/142 participants), the relative risk was 0.75 (95% CI 0.46 to 1.25), and for partial remission rates (CSII, 21/86 participants; MDI, 21/64), the relative risk was 0.74 (95% CI 0.45 to 1.24). The incidences of severe hypoglycaemia (CSII, 6/144; MDI, 2/149 participants) and DKA (CSII, 2/144 participants; MDI, 0/149 participants) were low. In total, 68 AEs (14 serious) were reported during CSII treatment and 25 AEs (eight serious) were reported during MDI treatment. Growth outcomes did not differ. The reported insulin use was higher with CSII (mean difference 0.1 unit/kg/day, 95% CI 0.0 to 0.2 unit/kg/day; p = 0.01). QoL was slightly higher for those randomised to CSII. From a NHS perspective, CSII was more expensive than MDI mean total cost (£1863, 95% CI £1620 to £2137) with no additional QALY gains (-0.006 QALYs, 95% CI -0.031 to 0.018 QALYs). LIMITATIONS Generalisability beyond 12 months is uncertain. CONCLUSIONS No clinical benefit of CSII over MDI was identified. CSII is not a cost-effective treatment in patients representative of the study population. FUTURE WORK Longer-term follow-up is required to determine if clinical outcomes diverge after 1 year. A qualitative exploration of patient and professional experiences of MDI and CSII should be considered. TRIAL REGISTRATION Current Controlled Trials ISRCTN29255275 and EudraCT 2010-023792-25.

Abstract
AIMS To assess HbA1c values and hospitalization rates before, during and after continuous subcutaneous insulin infusion (CSII) therapy. METHODS Demographic and hospitalization data were extracted from 161 individuals with Type 1 diabetes who received continuous subcutaneous insulin infusion (CSII) therapy between 2002 and 2013 at the Leeds Children and Young People's Diabetes Service for those aged < 20 years. The median (range) age at CSII start was 11.9 (1.1-17.6) years. The median (range) follow-up time was 2.3 (0-8.1) years. Random intercept models were used to compare HbA1c values before and during CSII initiation (and after CSII for those who discontinued it). Hospitalization rates were calculated for diabetic ketoacidosis and severe hypoglycaemia. RESULTS The mean HbA1c concentration decreased by 7 mmol/mol [95% CI 6-8; 0.6% (95% CI 0.5-0.7%)]. For the discontinued group (n=30), mean HbA1c decreased by 5 mmol/mol [95% CI 2-8; 0.4% (95% CI 0.2-0.7%)]. HbA1c returned to pre-CSII start levels at the end of this therapy. Diabetic ketoacidosis admissions increased threefold during CSII compared with before CSII start [2.2 per 100 person-years (95% CI 1.3 to 3.6) vs 7.4 per 100 person-years (95% CI 5.1 to 10.8)] and was highest during the first year of CSII. No difference in severe hypoglycaemia incidence rate was found during CSII compared with the pre-CSII period. CONCLUSIONS Despite significant reductions in HbA1c levels for individuals treated with CSII, improvements are needed to reduce diabetic ketoacidosis hospitalizations for those new to the therapy.

Abstract
BACKGROUND As evidence emerges that artificial pancreas systems improve clinical outcomes for patients with type 1 diabetes, the burden of this disease will hopefully begin to be alleviated for many patients and caregivers. However, reliance on automated insulin delivery potentially means patients will be slower to act when devices stop functioning appropriately. One such scenario involves an insulin infusion site failure, where the insulin that is recorded as delivered fails to affect the patient's glucose as expected. Alerting patients to these events in real time would potentially reduce hyperglycemia and ketosis associated with infusion site failures. METHODS An infusion site failure detection algorithm was deployed in a randomized crossover study with artificial pancreas and sensor-augmented pump arms in an outpatient setting. Each arm lasted two weeks. Nineteen participants wore infusion sets for up to 7 days. Clinicians contacted patients to confirm infusion site failures detected by the algorithm and instructed on set replacement if failure was confirmed. RESULTS In real time and under zone model predictive control, the infusion site failure detection algorithm achieved a sensitivity of 88.0% (n = 25) while issuing only 0.22 false positives per day, compared with a sensitivity of 73.3% (n = 15) and 0.27 false positives per day in the SAP arm (as indicated by retrospective analysis). No association between intervention strategy and duration of infusion sets was observed ( P = .58). CONCLUSIONS As patient burden is reduced by each generation of advanced diabetes technology, fault detection algorithms will help ensure that patients are alerted when they need to manually intervene.

Abstract
Since the 2000s, research teams worldwide have been working to develop closed-loop (CL) systems able to automatically control blood glucose (BG) levels in patients with type 1 diabetes. This emerging technology is known as artificial pancreas (AP), and its first commercial version just arrived in the market. The main objective of this paper is to present an extensive review of the clinical trials conducted since 2011, which tested various implementations of the AP for different durations under varying conditions. A comprehensive table that contains key information from the selected publications is provided, and the main challenges in AP development and the mitigation strategies used are discussed. The development timelines for different AP systems are also included, highlighting the main evolutions over the clinical trials for each system.

Abstract
OBJECTIVES The study assessed the psychosocial impact of the bihormonal bionic pancreas (BP) on adults in a real-world outpatient setting. RESEARCH DESIGN AND METHODS Thirty-nine adults with type 1 diabetes at four study centers across the U.S. participated in a two-arm, random-order, crossover design study: 11 days with the BP and 11 days with their usual care (UC). Psychosocial questionnaires were administered before the first study arm, at the end of the first study arm, and at the end of the second study arm. RESULTS The mean age of participants was 33 years; mean diabetes duration was 17 years; and 84% were non-Hispanic Caucasian. Significantly greater improvements in psychosocial outcomes were found following the use of BP versus UC; these included reductions in diabetes-related distress (P < 0.001) with the greatest drops in distress related to hypoglycemia and to eating constraints, and greater treatment satisfaction (P < 0.05). The majority of BP users described their experience as positive with a reduction in worrying about low (72%) and high (69%) blood sugars. The majority reported trusting the device (69%) and feeling less burdened by the BP than their usual method of diabetes care (64%). Concerns about the burden of the BP were also expressed, with >75% of users highlighting the burden of carrying around the equipment and the need to change glucagon daily, and more than half of the participants reporting concerns about wearability, discomfort, the time it took to correct out-of-range numbers, and "glitches" in the system. CONCLUSIONS Overall, participants report substantial psychosocial benefits accruing from the BP relative to their usual method of diabetes care. However, participants also reported a number of burdens associated with the system. Future versions of the BP device should be designed with the goal of addressing these concerns, and studies with larger, more diverse samples, and with more technology-naive participants are needed.

Abstract
BACKGROUND Continuous subcutaneous insulin infusion (CSII) therapy is a valuable option especially for people with type 1 diabetes. Although insulin infusion sets (IIS) are essential components of most insulin pump systems, only few studies have been conducted on their performance and safety. In this study 2 IIS with soft cannulas were compared. METHODS In an open-label, randomized, crossover, multicenter 8-week study 80 type 1 diabetic subjects on CSII (20-74 years, mean 46.5 ± 12.9 years, 58.8% male) were enrolled to evaluate the use of 2 IIS. The Accu-Chek® FlexLink Plus (FL Plus) and the Accu-Chek® FlexLink infusion set (FL) were used 4 weeks each under real-life conditions at home. All patients had to record details about every IIS change in a diary. Insertion-related pain was assessed by means of a visual analogue scale (VAS). RESULTS The mean pain noted during insertion was similar for both IIS (VAS 6.1 ± 6.4 mm for the FL Plus and 5.8 ± 6.3 mm for the FL, P = .92). 20.0% of the 895 IIS changes with FL Plus and 16.0% of the 854 with FL were unplanned. During the 4243 patient days of the study, 13 patients had adverse events. Among these, 2 serious adverse events occurred. Both serious events and 1 nonserious adverse event were considered as related to the IIS. Of the patients, 18.7% had kinked cannulas. Most patients were satisfied with both IIS. CONCLUSION Both IIS are safe and effective. The 2 IIS did not differ from each other with respect to pain observed during insertion.

Abstract
BACKGROUND The objectives of this study were to examine factors associated with insulin pump discontinuation among children and adults followed longitudinally for 1 year in the multicenter T1D Exchange clinic registry, and to provide participant-reported reasons for stopping pump therapy. METHODS We longitudinally followed 8935 participants of all ages using an insulin pump at the time of registry enrollment. Logistic regressions were used to identify demographic and clinical factors associated with pump discontinuation. Pump discontinuation was self-reported by participants on a first annual follow-up survey. RESULTS The overall frequency of pump discontinuation was 3%. Discontinuation was higher in adolescents (4%) and young adults (4%) than in younger children (3%) or older adults (1%). In multivariate analysis of children between 6 and <13 and 13 and <18 years, participants who discontinued pump use were more likely to have higher HbA1c levels at baseline (adjusted P < .001 for both). The top participant-reported reasons for discontinuing the pump included problems with wearability (57%), disliking the pump or feeling anxious (44%), and problems with glycemic control (30%). CONCLUSIONS In T1D Exchange registry participants, insulin pump discontinuation is uncommon, but more prevalent among adolescents and young adults, and youth with poor glycemic control. Given the known benefits of pump therapy, these populations should be targeted for support and education on troubleshooting pump use. Common reasons for discontinuation should also be considered in future device design and technological improvement.

Abstract
OBJECTIVE Diabetes devices (insulin pumps, continuous glucose monitors [CGMs]) are associated with benefits for glycemic control, yet uptake of these devices continues to be low. Some barriers to device uptake may be modifiable through psychosocial intervention, but little is known about which barriers and which patients to target. RESEARCH DESIGN AND METHODS We surveyed 1,503 adult T1D Exchange participants (mean age 35.3 [SD 14.8] years, mean diagnosis duration 20.4 [SD 12.5] years) to investigate barriers to device uptake, understand profiles of device users versus nonusers, and explore differences by age and sex. Scales used were the Diabetes Distress Scale, Technology Use Attitudes (General and Diabetes-Specific), and Barriers to Device Use and Reasons for Discontinuing Devices. RESULTS Most commonly endorsed modifiable barriers were related to the hassle of wearing devices (47%) and disliking devices on one's body (35%). CGM users (37%) were older than nonusers (mean 38.3 vs. 33.5 years), had diabetes for longer (22.9 vs. 18.8 years), had more positive technology attitudes (22.6-26.0 vs. 21.4-24.8), and reported fewer barriers to using diabetes technology than nonusers (3.3 vs. 4.3). The youngest age-group (18-25 years) had the lowest CGM (26% vs. 40-48%) and insulin pump (64% vs. 69-77%) uptake, highest diabetes distress (2.2 vs. 1.8-2.1), and highest HbA1c levels (8.3% [67 mmol/mol] vs. 7.2-7.4% [55-57 mmol/mol]). CONCLUSIONS Efforts to increase device use need to target physical barriers to wearing devices. Because young adults had the lowest device uptake rates, highest distress, and highest HbA1c compared with older age-groups, they should be the focus of future interventions to increase device use.

Abstract
Few studies have explored durability of insulin pump use, and none have explored the link between depression and pump discontinuation. To examine the relationship between depressive symptoms [measured by the Children's Depression Inventory (CDI)], method of insulin delivery, and hemoglobin A1c (A1c), mixed models were used with data from 150 adolescents with type 1 diabetes (T1D) and visits every 6 months for 2 years. Of the 63% who used a pump, compared with multiple daily injections (MDI) at baseline, there were higher proportions who were non-minorities, had caregivers with a college degree, private insurance, and two caregivers in the home (p ≤ 0.01). After adjusting for time, sex, age, T1D duration, frequency of blood glucose monitoring, ethnicity, insurance, and caregiver number and education, baseline pump use was associated with -0.79% lower mean A1c [95% confidence interval (CI): -1.48, -0.096; p = 0.03]. For those using a pump at baseline, but switching to MDI during the study (n = 9), mean A1c was 1.38% higher (95% CI: 0.68, 2.08; p < 0.001) than that for those who did not switch method of delivery. A 10-point increase in CDI was associated with a 0.39% increase in A1c (95% CI: 0.16, 0.61; p = 0.001), independent of pump use. Regarding the temporal relationship between CDI score and changing method of insulin delivery, prior higher CDI score was associated with switching from pump to MDI (odds ratio = 1.21; 95% CI: 1.05, 1.39; p = 0.007). Clinicians should be aware of the associations between depressive symptoms, change in insulin delivery method, and the effect on glycemic control.

Abstract
Large epidemiological databases are often used to examine matters pertaining to drug utilization, health services, and drug safety. The major strength of such databases is that they include large sample sizes, which allow precise estimates to be made. The IMS® LRx database has in recent years been used as a data source for epidemiological research. The aim of this paper is to review a number of recent studies published with the aid of this database and compare these with the results of similar studies using independent data published in the literature. In spite of being somewhat limited to studies for which comparative independent results were available, it was possible to include a wide range of possible uses of the LRx database in a variety of therapeutic fields: prevalence/incidence rate determination (diabetes, epilepsy), persistence analyses (diabetes, osteoporosis), use of comedication (diabetes), drug utilization (G-CSF market) and treatment costs (diabetes, G-CSF market). In general, the results of the LRx studies were found to be clearly in line with previously published reports. In some cases, noticeable discrepancies between the LRx results and the literature data were found (e.g. prevalence in epilepsy, persistence in osteoporosis) and these were discussed and possible reasons presented. Overall, it was concluded that the IMS® LRx database forms a suitable database for pharmacoepidemiological studies.

Abstract
Technological innovations have revolutionized the treatment of type 1 diabetes. Although technological advances can potentially improve diabetes outcomes, maintenance of target glycemic control, at the present time, remains largely dependent on patient and family motivation, competence, and adherence to daily diabetes care requirements. Trials of closed loop or "artificial pancreas" technology show great promise to automate insulin delivery and achieve near normal glucose control and reduced hypoglycemia with minimal patient intervention.

Abstract
Insulin pump therapy, also known as continuous subcutaneous insulin infusion (CSII), is an important and evolving form of insulin delivery, which is mainly used for people with type 1 diabetes. However, even with modern insulin pumps, errors of insulin infusion can occur due to pump failure, insulin infusion set (IIS) blockage, infusion site problems, insulin stability issues, user error or a combination of these. Users are therefore exposed to significant and potentially fatal hazards: interruption of insulin infusion can result in hyperglycaemia and ketoacidosis; conversely, delivery of excessive insulin can cause severe hypoglycaemia. Nevertheless, the available evidence on the safety and efficacy of CSII remains limited. The European Association for the Study of Diabetes (EASD) and American Diabetes Association (ADA) have therefore joined forces to review the systems in place for evaluating the safety of pumps from a clinical perspective. We found that useful information held by the manufacturing companies is not currently shared in a sufficiently transparent manner. Public availability of adverse event (AE) reports on the US Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database is potentially a rich source of safety information but is insufficiently utilised due to the current configuration of the system; the comparable database in Europe (European Databank on Medical Devices, EUDAMED) is not publicly accessible. Many AEs appear to be attributable to human factors and/or user error, but the extent to which manufacturing companies are required by regulators to consider the interactions of users with the technical features of their products is limited. The clinical studies required by regulators prior to marketing are small and over-reliant on bench testing in relation to 'predicate' products. Once a pump is available on the market, insufficient data are made publicly available on its long-term use in a real-world setting; such data could provide vital information to help healthcare teams to educate and support users, and thereby prevent AEs. As well as requiring more from the manufacturing companies, we call for public funding of more research addressing clinically important questions in relation to pump therapy: both observational studies and clinical trials. At present there are significant differences in the regulatory systems between the USA and European Union at both pre- and post-marketing stages; improvements in the European system are more urgently required. This statement concludes with a series of recommended specific actions for 'meknovigilance' (i.e. a standardised safety approach to technology) which could be implemented to address the shortcomings we highlight.

Abstract
AIM This study aimed to systematically review the evidence base for the use of existing psychological and psychosocial measures suitable for use in artificial pancreas (AP) research. MATERIALS AND METHODS This systematic review of published literature, gray literature, previous systematic reviews, and qualitative and economic studies was conducted using terms and abbreviations synonymous with diabetes, AP, and quality of life (QoL). RESULTS Two hundred ninety-two abstracts were identified that reported psychosocial assessment of diabetes-related technologies. Of these, nine met the inclusion criteria and were included. Only four of 103 ongoing trials evaluated psychosocial aspects as an outcome in the trial. Of these, treatment satisfaction, acceptance and use intention of AP, fear of hypoglycemia episodes, satisfaction with AP, and an unspecified QoL measure were used. CONCLUSIONS A better understanding of the psychosocial side of AP systems and the extent to which human factors play a role in the uptake and efficient use of these systems will ultimately lead to the most benefit for people with diabetes.

Abstract
Type 1 diabetes is a chronic autoimmune disease that affects mainly young people. In the last 50 years, a steady increase of the T1D incidence in the young is reported worldwide, with an average 4 % increase annually. In addition, the mean age at the diagnosis is decreasing. Studies show that good metabolic control is important not only for delaying the chronic complications of diabetes but also for improving the quality of life of patients and their families. Continuous education, together with modern technology, is crucial in achieving these goals. Longitudinal data on glycated hemoglobin (HbA1c), along with the data on severe hypoglycemia and severe diabetic ketoacidosis, can describe the quality of care in a defined population. Two national reference diabetes centres taking care of children, adolescents and young adults with diabetes in Israel and Slovenia are described.

Abstract
AIMS This study assesses the impact of using an AP-system at home on fear of hypoglycaemia. In addition, satisfaction and acceptance of the new technology are evaluated. METHODS In a multicentre, multinational study of 75 patients using the MD-Logic AP during four consecutive nights in home setting 59 of them (aged 10-54 years, 54% male, HbA1c 7.89 ± 0.69% [62.72 ± 7.51 mmol/mol], diabetes duration 11.6 ± 8.4 yrs) answered standardized questionnaires (HFS, adapted TAM, and AP satisfaction) before and after using the AP. RESULTS After experiencing the AP in home setting worries of hypoglycaemia were significantly reduced (before 1.04 ± 0.53 versus after 0.90 ± 0.63; P = 0.017). Perceived ease of use as a measure of acceptance with the AP significantly increased after personal experience (before 4.64 ± 0.94 versus after 5.06 ± 1.09; P = 0.002). The overall satisfaction mean score after using the AP was 3.02 ± 0.54 (range 0-4), demonstrating a high level of satisfaction with this technology. CONCLUSIONS The four-night home-based experience of using MD Logic AP was associated with reduced worries of hypoglycaemia, high level of satisfaction, and increased perceived ease of use of the new technology in children, adolescents, and adults.

Abstract
BACKGROUND Previous studies have shown that only a small number of pediatric and young adult patients discontinue pump therapy, but risk factors for discontinuation are unclear. OBJECTIVE To identify characteristics of pediatric and young adult patients with pump therapy which are associated with discontinuation of treatment. SUBJECTS AND METHODS Retrospective cohort study using a representative nationwide database (LRx; IMS Health) in Germany covering >80% of all prescriptions to members of statutory health insurances in 2008-2011. All patients (age group <25 years) with new prescriptions of insulin pumps were identified (2009-2010) and were followed for 12 months. RESULTS Overall, 2452 new pump users were identified, of whom 177 (7.2%) switched to other forms of insulin therapy within 12 months. In multivariate logistic regression, younger age (<6 years; reference 18 to <25 years: Odds ratio, OR, 95% CI: 0.36; 0.17-0.74) and use of teflon needles (reference steel needles: OR, 95% CI: 0.59; 0.41-0.83) were related to a lower odds of pump discontinuation. A non-significant trend was found for male sex (OR, 95% CI: 0.75; 0.52-1.08). Prescriptions of thyroid therapeutics (ATC H03A: OR, 95% CI: 1.79; 1.23-2.61) and antiepileptics (N03: OR, 95% CI: 3.14; 1.49-6.59) were significantly associated with discontinuation of pump therapy. CONCLUSIONS About 93% of pediatric and young adult patients maintained insulin pump therapy within 12 months. Age <6 years, male sex and teflon needle use were associated with a lower risk of discontinuation. Thyroid therapy (indicating autoimmunity) and antiepileptic drug prescriptions were associated with a higher likelihood for discontinuation of insulin pump treatment.

Abstract
BACKGROUND Insulin pumps (for continuous subcutaneous insulin infusion [CSII]) are used widely in type 1 diabetes mellitus. Although there has been considerable study of outcomes, there are few recent data on CSII-associated adverse events and no data on family perceptions of adverse events and their confidence in dealing with them. SUBJECTS AND METHODS We approached all families of children and adolescents ≤ 19 years of age on CSII attending the diabetes clinic over a 16-week clinic cycle. Participants completed a retrospective questionnaire examining issues over the previous 12 months. Data on pump adverse events as well as answers to questions pertaining to education and confidence were collected. RESULTS Our survey received a response rate of 99%, with 235 of the 238 families approached participating. In the preceding 12 months, 104 of 230 (45%) had reported at least one pump-related adverse event (either mechanical or set-related), with an associated 52 of 229 (23%) resulting in pump replacement. This equated to a minimum incidence density of 53 adverse events/100 person-years. Additionally, 18 of 230 (8%) reported a hospital admission or emergency department attendance as a consequence. Pump malfunction and infusion set/site failures were the most common events reported, with one or more events in 58 of 104 (56%) and 47 of 104 (45%), respectively. Adverse events, excluding set/site failures, were associated with older age (13.1 ± 3.4 years vs. 11.9 ± 4 years; P = 0.02). CONCLUSIONS This is the first study to look at family perceptions of adverse events while using modern CSII. It highlights a high self-reported rate of CSII-related adverse events, pump replacement, and subsequent presentation to the hospital. Potential areas for additional targeted education are identified. Further prospective study examining pump adverse event characteristics and incidence is warranted.

Abstract
We evaluated the long-term glycemic control in children with type 1 diabetes, using continuous subcutaneous insulin infusion (CSII) for at least 5 years in three diabetes centers from three different countries: Canada, Italy and Spain. This was an observational retrospective multicenter cohort study. Subjects were included if they were followed at one of the participating centers, had type 1 diabetes, age 5-20 years at time of data collection and used CSII for more than 5 years. Data collected included gender, age, disease duration, age at CSII initiation, body mass index (BMI), hemoglobin A1c (HbA1c), insulin requirement and serious adverse events (SAE) at baseline and every 12 months during follow-up. One hundred fifteen patients were included in the study (55% males), aged 5-20 years (mean: 13.5 ± 3.8 years), with mean diabetes duration of 6.3 ± 3.4 years, using CSII for mean of 6.9 ± 1.2 years (range 5-12 years.). HbA1c significantly improved after 1 year of CSII treatment and during follow-up (p = 0.02). When HbA1c was compared between countries, a difference was observed, with slightly lower values in Italy than in Canada and Spain (p = 0.04). When evaluated by gender, HbA1c was similar at baseline, but significantly improved only in males during all follow-up (p = 0.004). No significant differences were observed for BMI, insulin requirement or SAE. Insulin pump therapy is safe and effective in the pediatric population, although in this study, the major benefit in HbA1c was seen in males. The use of advanced pump features was associated with greater improvement in HbA1c.

Abstract
Optimal use of recent technological advances in insulin delivery and glucose monitoring remain limited by the impact of behaviour on self-care. In recent years, there has been a resurgence of interest in psychosocial methods of optimizing care in youth with type 1 diabetes. We therefore sought to examine the literature for demographic, interpersonal and intrapersonal correlates of self-care and/or metabolic control. Studies for this systematic review were obtained via an electronic search of Medline, Embase, Cumulative Index to Nursing and Allied Health Literature and PsycINFO databases. Seventy studies fulfilled the inclusion criteria. These studies have indicated that identifiable individual characteristics in each domain are robustly associated with metabolic control and/or self-care in children and adolescents. We present these characteristics and propose a theoretical model of their interactions and effect on diabetes outcomes. There is currently no consensus regarding patient selection for insulin pump therapy. In this era of scarce healthcare resources, it may be prudent to identify youth requiring increased psychosocial support prior to regimen intensification. The importance of this review lies in its potential to create a framework for rationally utilizing resources by stratifying costly therapeutic options to those who, in the first instance, will be most likely to benefit from them.

Abstract
Continuous subcutaneous insulin infusion (CSII) is effective and safe in children and adults with type 1 diabetes. Notwithstanding, some patients decide to discontinue using CSII. We evaluated the discontinuation rate, and its related factors, in a large group of children and adolescents with type 1 diabetes using CSII in Italy. Data on all patients with type 1 diabetes younger than 18 years were collected by 28 Pediatric Diabetologic referral Centers located throughout Italy. The primary endpoint was to measure the discontinuation rate using CSII. Among the study population (n = 6,644), 985 (14.8%) were using CSII. Sixty patients discontinued using CSII, representing the 6.1%. The discontinuation rate significantly increased (P = 0.002) with age: 0-6 years, 1/84 (1.2%), 7-11 years, 8/262 (3.1%), 12-18 years, 51/579 (8.8%). The average time to discontinuation was 1.8 ± 1.4 years. The average age of patients who discontinued using CSII was higher than in patients still on CSII (12.1 ± 3.2 vs. 10.3 ± 3.8, P = 0.0001), while their diabetes duration was significantly shorter (8.6 ± 2.7 vs. 10.2 ± 3.7, P = 0.0001). HbA1c decreased only in patients still on CSII (8.7 ± 1.3% vs. 7.8 ± 1.3%, P = 0.02), but not in patients who discontinued using CSII (8.5 ± 1.6% vs. 8.2 ± 1.3%, P = 0.213). HbA1c might be one important indicator helpful to identify patients at higher risk discontinuing using CSII.

Abstract
BACKGROUND Growing technological improvements in insulin pump design have increased the use of these devices in young children. To better understand the types of infusion pump-related problems and associated adverse events in this age group, we performed a comprehensive evaluation of pump-related adverse event reports received by the U.S. Food and Drug Administration (FDA) for children ages 1-12 years. METHODS A query was conducted of FDA's Manufacturer and User Facility Device Experience database from January 1, 1996, through December 31, 2009, in children ages 1-12 years involving insulin pumps. Report narratives were individually reviewed for age, gender, and seriousness of outcomes. Device or patient problems and potential contributory factors were assessed. RESULTS Over the past 14 years, 1774 (7%) of all insulin pump adverse event reports were identified in children ages 1-12. Of these reports, 777 (43%) resulted in hospitalization. In hospitalized cases (n = 614), diabetic ketoacidosis and/or hyperglycemia were the predominant patient problems, and in other cases (n = 98), hypoglycemia was evident. There were 106 emergency room visits, 19 cases requiring paramedic attention, and five deaths. The majority of reports indicated that the devices were not returned to the manufacturer, and root causes were not always confirmed. CONCLUSIONS Younger children with diabetes deserve careful consideration of the risk and benefit of insulin pump technology. Studies are needed to better understand pediatric safety issues and to identify the root cause of adverse events. Problems related to patient education, device misuse, and malfunctions were found, highlighting the need to strengthen user training for children and their caregivers.

Abstract
Continuous subcutaneous insulin infusion from an insulin pump depends on reliable transfer of the pumped insulin to the subcutaneous insulin depot by means of an insulin infusion set (IIS). Despite their widespread use, the published knowledge about IISs and related issues regarding the impact of placement and wear time on insulin absorption/insulin action is relatively small. We also have to acknowledge that our knowledge is limited with regard to how often patients encounter issues with IISs. Reading pump wearer blogs, for instance, suggests that these are a frequent source of trouble. There are no prospective clinical studies available on current IIS and insulin formulations that provide representative data on the type and frequency of issues with infusion sets. The introduction of new IISs and patch pumps may foster a reassessment of available products and of patient problems related to their use. The aim of this review is to summarize the current knowledge and recommendations about IISs and to highlight potential directions of IIS development in order to make insulin absorption safer and more efficient.

Abstract
Since 2000, the diabetes community has witnessed tremendous technological advances that have revolutionized diabetes management. Currently, closed-loop glucose control (CLC) systems, which link continuous subcutaneous insulin infusion and continuous glucose monitoring, are the newest, cutting edge technology aimed at reducing glycemic variability and improving daily management of diabetes. Although advances in knowledge and technology in the treatment of diabetes have improved exponentially, adherence to diabetes regimens remains complex and often difficult to predict. Human factors, such as patient perceptions and behavioral self-regulation, are central to adherence to prescribed regimens, as well as to adoption and utilization of diabetes technology, and they will continue to be crucial as diabetes management evolves. Thus, the aims of this article are three-fold: (1) to review psychological and behavioral factors that have influenced adoption and utilization of past technologies, (2) to examine three theoretical frameworks that may help in conceptualizing relevant patient factors in diabetes management, and (3) to propose patient-selection factors that will likely affect future CLC systems.
