[PMID: 38685543 DOI: 10.1016/j.ijbiomac.2024.131876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2024] [Revised: 04/18/2024] [Accepted: 04/24/2024] [Indexed: 05/02/2024]
Abstract
Buccal mucosa administration is a promising method for insulin (INS) delivery with good compliance. However, buccal mucosa delivery systems still face challenges of long-term mucosal adhesion, sustained drug release, and mucosal drug penetration. To address these issues, a double-layer film consisting of a hydroxypropyl methylcellulose/polyacrylic acid interpolymer complex (IPC)-formulated mucoadhesive layer and an ethylcellulose (EC)-formulated waterproof backing layer (IPC/EC film) was designed. Protamine (PTM) and INS were co-loaded in the mucoadhesive layer of the IPC/EC film (PTM-INS-IPC/EC film). In ex vivo studies with porcine buccal mucosa, this film exhibited robust adhesion, with an adhesion force of 120.2 ± 20.3 N/m2 and an adhesion duration of 491 ± 45 min. PTM has been shown to facilitate INS mucosal transfer. Pharmacokinetic studies indicated that the PTM-INS-IPC/EC film significantly improved the absorption of INS, exhibiting a 1.45 and 2.24-fold increase in the area under the concentration-time curve (AUC0-∞) compared to the INS-IPC/EC film and free INS, respectively. Moreover, the PTM-INS-IPC/EC film effectively stabilized the blood glucose levels of type 1 diabetes mellitus (T1DM) rats with post oral glucose administration, maintaining lower glucose levels for approximately 8 h. Hence, the PTM-INS-IPC/EC film provides a promising noninvasive INS delivery system for diabetes treatment.

Abstract
Diabetes technology has proliferated extensively over the past few decades with vast ameliorations in glucose monitoring and in insulin delivery systems. From a treatment based on daily insulin injections, we have moved to increasingly advanced technologies. Despite such advancements which have allowed better glycemic control, decreased diabetes-related complications, and improved the quality of life among diabetic patients, it has left many individuals unsatisfied with the current rate of commercial artificial pancreas development, stemming the need for further research into novel technologies. Accordingly, the Juvenile Diabetes Research Foundation has marked three generations for the development of an artificial pancreas comprising historical landmarks and future prospects which aim to produce an advanced technological system that attempts to mimic the endogenous pancreas, eliminating the need for user input. This review presents a synopsis of the development and evolution of insulin pumps, starting with the earliest technologies available such as continuous subcutaneous insulin infusion and continuous glucose monitoring as separate components, to currently available integrated advanced closed-loop hybrid systems and possible future technologies. The aim of the review is to provide insight of the advantages and limitations of past and currently available insulin pumps with the hope of driving research into novel technologies that attempt to mimic endogenous pancreatic function as closely as possible.

Abstract
The discovery of insulin was presented to the international medical community on May 3, 1922. Since then, insulin has become one of the most effective pharmacological agents used to treat type 1 and type 2 diabetes mellitus. However, the initiation and intensification of insulin therapy is often delayed in people living with type 2 diabetes due to numerous challenges associated with daily subcutaneous administration. Reducing the frequency of injections, using insulin pens instead of syringes and vials, simplifying treatment regimens, or administering insulin through alternative routes may help improve adherence to and persistence with insulin therapy among people living with diabetes. As the world commemorates the centennial of the commercialization of insulin, the aims of this article are to provide an overview of insulin therapy and to summarize clinically significant findings from phase 3 clinical trials evaluating less frequent dosing of insulin and the non-injectable administration of insulin.

Abstract
Continuous subcutaneous insulin infusion (CSII) is an essential insulin replacement therapy in the management of diabetes. However, the longevity of clinical CSII is limited by skin complications, by impaired insulin absorption and by occlusions associated with the subcutaneous insertion of CSII catheters, which require replacement and rotation of the insertion site every few days. Here we show that a biodegradable zwitterionic gel covering the tip end of commercial off-the-shelf CSII catheters fully resolves early skin irritations, extends the longevity of catheters and improves the rate of insulin absorption (also with respect to conventional syringe-based subcutaneous injection) for longer than 6 months in diabetic mice, and by 11 days in diabetic minipigs (from 2 to 13 days, under standard CSII-wearing conditions of insulin pump therapy and in a continuous basal-plus-bolus-infusion setting). The implanted gel displayed anti-inflammatory and anti-foreign-body-reaction properties and promoted the local formation of new blood vessels. The gel is subcutaneously injected before the tip of catheter is inserted into it, and should be generally applicable to CSII catheters and other implantable devices.

Abstract
OBJECTIVE To determine the impact of switching from the predictive low glucose suspend (PLGS) system to the advanced hybrid Tandem Control-IQ system on glucometrics and glycosylated haemoglobin (HbA1c) at one year. To assess the impact on the quality of life perceived by parents. METHOD Prospective study in 71 patients aged 6-18 years with type 1 diabetes (DM1), in treatment with PLGS, who switched to an advanced hybrid system. Glucometric data were collected before the change, at 4 and 8 weeks, and at one year of use; HbA1c before the change and after one year. The Diabetes Impact and Devices Satisfaction (DIDS) questionnaire was used at weeks 4 and 8. RESULTS An increase in time in range (TIR) was observed with a median of 76% (P<.001) at 4 weeks, which was maintained after one year (+8% in the total group). Overall, 73.24% of patients achieved a TIR above 70%. The subgroup with an initial TIR of less than 56% increased it by 14.4%. After one year there was a 0.3% reduction in HbA1c. Level 1 hypoglycaemia, level 1 and level 2 hyperglycaemia, mean glucose (GM) and coefficient of variation (CV) decreased. Auto mode stayed on 97% of the time and no dropouts occurred. Caregivers had a perception of better glycaemic control and less need to monitor blood glucose variations during the night. None of them would switch back to the previous system and they feel safe with the new system. CONCLUSIONS The Tandem Control-IQ advanced hybrid system was shown to be effective one year after its implementation with improvement in all glucometric parameters and HbA1c, as well as night-time rest in caregivers.

Abstract
Objective: This study examined subcutaneous tissue changes at sites used by continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM), and tested whether these changes, if any, were associated with glycated hemoglobin (HbA1c). Research Design and Methods: This prospective study investigated recently used CSII or CGM sites in 161 children and adolescents during the first year after initiation of a new diabetes device. Subcutaneous changes such as echogenicity, vascularization, and the distance from the skin surface to the muscle at CSII and CGM sites were assessed by ultrasound. Results: The distance from skin surface to muscle fascia at both the upper arm and abdomen was influenced by age, body mass index z-score, and sex. Especially in boys and the youngest, the depth of many devices outreached the mean distance. The mean distance for boys at the abdomen and upper arm ranged from 4.5-6.5 mm and 5-6.9 mm for all ages, respectively. Hyperechogenicity at CGM sites was 4.3% after 12 months. The frequency of subcutaneous hyperechogenicity and vascularization at CSII sites increased significantly over time (41.2% to 69.3% and 2% to 16% respectively, P < 0.001 and P = 0.009). Hyperechogenicity in the subcutis was not a predictor of elevated HbA1c (P = 0.11). Conclusion: There is large variation in the distance from the skin surface to the muscle fascia and many diabetes devices reach even deeper. Hyperechogenicity and vascularization increased significantly over time at CSII sites, but not CGM sites. The importance of hyperechogenicity for insulin absorption is unclear and further investigations are needed. Clinical Trial Registration number: NCT04258904.

Abstract
Diabetic ketoacidosis (DKA) represents an acute, severe complication of relative insulin deficiency and a common presentation of Type 1 Diabetes Mellitus (T1DM) primarily and, occasionally, Type 2 Diabetes Mellitus (T2DM) in children and adolescents. It is characterized by the biochemical triad of hyperglycaemia, ketonaemia and/or ketonuria, and acidaemia. Clinical symptoms include dehydration, tachypnoea, gastrointestinal symptoms, and reduced level of consciousness, precipitated by a variably long period of polyuria, polydipsia, and weight loss. The present review aims to summarize potential pitfalls in the diagnosis and management of DKA. A literature review was conducted using the Pubmed/Medline and Scopus databases including articles published from 2000 onwards. Diagnostic challenges include differentiating between T1DM and T2DM, between DKA and hyperosmolar hyperglycaemic state (HHS), and between DKA and alternative diagnoses presenting with overlapping symptoms, such as pneumonia, asthma exacerbation, urinary tract infection, gastroenteritis, acute abdomen, and central nervous system infection. The mainstays of DKA management include careful fluid resuscitation, timely intravenous insulin administration, restoration of shifting electrolyte disorders and addressing underlying precipitating factors. However, evidence suggests that optimal treatment remains a therapeutic challenge. Accurate and rapid diagnosis, prompt intervention, and meticulous monitoring are of major importance to break the vicious cycle of life-threatening events and prevent severe complications during this potentially fatal medical emergency.

Abstract
BACKGROUND Insulin pump therapy is a real breakthrough in managing diabetes Mellitus, particularly in children. It can deliver a tiny amount of insulin and decreases the need for frequent needle injections. It also helps to maintain adequate and optimal glycemic control to reduce the risk of metabolic derangements in different tissues. Children are suitable candidates for pump therapy as they need a more freestyle and proper metabolic control to ensure adequate growth and development. Therefore, children and their caregivers should have proper education and training and understand the proper use of insulin pumps to achieve successful pump therapy. The pump therapy continuously improves to enhance its performance and increase its simulation of the human pancreas. Nonetheless, there is yet a long way to reach the desired goal.
AIM To review discusses the history of pump development, its indications, types, proper use, special conditions that may enface the children and their families while using the pump, its general care, and its advantages and disadvantages.
METHODS We conducted comprehensive literature searches of electronic databases until June 30, 2022, related to pump therapy in children and published in the English language.
RESULTS We included 118 articles concerned with insulin pumps, 61 were reviews, systemic reviews, and meta-analyses, 47 were primary research studies with strong design, and ten were guidelines.
CONCLUSION The insulin pump provides fewer needles and can provide very tiny insulin doses, a convenient and more flexible way to modify the needed insulin physiologically, like the human pancreas, and can offer adequate and optimal glycemic control to reduce the risk of metabolic derangements in different tissues.

Abstract
AIMS (1) To describe the population of patients with type 1 diabetes (T1DM) using the rapid-acting insulin analogue glulisine versus lispro and aspart during continuous subcutaneous insulin infusion (CSII); (2) to describe insulin relative effectiveness based on hemoglobin A1c (HbA1c), fasting blood glucose (FBG) and dose; (3) to determine rates of hyperglycemia, hypoglycemia, and diabetic ketoacidosis (DKA). METHODS The analysis used March 2021 data from the Diabetes-Patienten-Verlaufsdokumentation registry, which contains data of 618,903 patients with diabetes. Patients were propensity-matched by age, sex, and diabetes duration. RESULTS Overall, 42,736 patients of any age were eligible for analysis based on insulin pump usage with either glulisine (N = 707) or lispro/aspart (N = 42,029) between 2004 and 2020. Patients receiving glulisine were older (median 20.0 vs. 16.2 years), equally often male (47.2% vs. 47.8%) and had a longer diabetes duration (median 9.4 vs. 7.4 years). After propensity score matching, 707 pairs remained (total N = 1414). Patient characteristics between groups were similar. Achieved HbA1c values were also comparable: 8.04%, 64 mmol/mol versus 7.96%, 63 mmol/mol for glulisine and lispro/aspart [LS mean difference 0.08 (95%CI - 0.08, 0.25)]. FBG was 9.37 mmol/L (168.9 mg/dL) and 9.58 mmol/L (172.6 mg/dL) in the glulisine and lispro/aspart groups [LS mean diff. - 0.21; (95%CI - 1.13, 0.72)]. Total daily insulin doses and prandial to total insulin ratios were also similar. Glulisine group patients had higher rates of lipodystrophy (0.85% vs. 0.71%) (LS mean diff. 0.18 [95% CI - 1.01, 1.38]) and non-severe DKA (3.11% vs. 0.57%; p = 0.002). Fewer patients in the glulisine group had severe hypoglycemic events (7.66 vs. 9.09; p = 0.333) and severe ketoacidosis events (0.57% vs. 1.56%; p = 0.082) but more had hypoglycemic coma events (p = 0.773), although the differences were not statistically significant. CONCLUSIONS Insulin glulisine had comparable glucose control to lispro/aspart. The use of glulisine was less frequent in the present analysis compared to the previous trials.

Abstract
Diabetes technology has rapidly evolved, and insulin infusion pumps (IIPs) have gained worldwide acceptance in diabetes care. The safety of medical equipment is highly discussed, imposing complex challenges in its use. The accuracy of IIPs can be determined through laboratory tests, generally following the IEC 60601-2-24 protocol. Studies have evaluated the accuracy and precision of IIPs, and there are discrepant results. So, we conducted a Systematic Literature Review to assess the methodologies used to evaluate the accuracy of IIPs, organizing the findings in a compiled perspective. The methodology was based on Kitchenham and Biolchini guidelines, and when possible it was carried out the Bayesian meta-analyses to compare the accuracy of IIPs. Most studies used the microgravimetric technique to evaluate the device accuracy, and some proposed adaptations for the standard protocol. The variation of results was recurrent, and the establishment of a protocol, especially to evaluate patch pumps, is necessary. The present study gives enough data to understand the scenario of the IIPs evaluation, as well as the different protocols that can be explored for its evaluation. This highlights the need for a reliable, practical, and low-cost methodology to assist the evaluation of IIPs.

Abstract
A new insulin patch pump for continuous subcutaneous insulin infusion was developed. The pump is composed of reusable and disposable parts and operates with a stepping motor. This pump was compared to a patch pump and a durable pump regarding basal rate and bolus accuracy. Using a microgravimetric method, boluses of 0.2 U, 1 U and 7 U, and a basal rate of 1 U/h were tested. For all pumps, bolus accuracy was higher when larger volumes were delivered. While median deviations were similar for all pumps, there were differences in the precision of individual boluses and when regarding basal rate delivery divided into 1-h windows.

Abstract
As cystic fibrosis transmembrane regulator (CFTR) modulator therapies offer greater longevity and improved health quality, women living with cystic fibrosis (CF) are increasingly pursuing pregnancy. Maternal risks for pregnant women with CF largely depend on a woman's baseline pulmonary and pancreatic function, and the majority of CF pregnancies will successfully end in live births. Diabetes, either gestational or pre-existing cystic fibrosis-related diabetes (CFRD), is highly prevalent in women with CF, affecting 18 to 62% of pregnancies in recent CF center reports. In addition to the rising incidence of CFRD with age, gestational diabetes is also more common in women with CF due to lower insulin secretion, higher insulin resistance, and increased hepatic glucose production as compared to pregnant women without CF. Diabetes occurring during pregnancy has important implications for maternal and fetal health. It is well established in women without CF that glycemic control is directly associated with risks of fetal malformation, neonatal-perinatal mortality, cesarean delivery and need for neonatal intensive care. Small studies in women with CF suggest that pregnancies affected by diabetes have an increased risk of preterm delivery, lower gestational age, and lower fetal birth weight compared to those without diabetes. Women with CF preparing for pregnancy should be counseled on the risks of diabetes and should undergo routine screening for CFRD with oral glucose tolerance testing (OGTT) if not already completed in the past six months. Glycemic control in those with pre-gestational CFRD should be optimized prior to conception. Insulin is preferred for the management of diabetes in pregnant women with CF via multiple daily injections or insulin pump therapy, and continuous glucose monitors (CGM) can be useful in mitigating hypoglycemia risks. Women with CF face many unique challenges impacting diabetes care during pregnancy and would benefit from support by a multidisciplinary care team, including nutrition and endocrinology, to ensure healthy pregnancies.

Abstract
AIMS The objective of the study was to compare grade point averages (GPAs) on compulsory school exit exams (exam GPA) and educational attainment at age 16 and 20 for individuals with and without type 1 diabetes. METHODS This study was a population-based retrospective cohort study, which included the 1991 to 1998 birth cohorts in Denmark. Follow-up was conducted at age 16 and 20 (follow-up period; 1 January, 2007 to 31 December, 2018). There were 2083 individuals with and 555,929 individuals without type 1 diabetes. Linear regression and generalized linear models compared outcomes with and without adjustments for socio-economic characteristics. RESULTS A total of 558,012 individuals (51% males) were followed to the age of 20. Having type 1 diabetes was associated with a lower exam GPA when adjusting for socio-economic status (difference: -0.05 (95% CI, -0.09 to -0.01), a higher relative risk of not completing compulsory school by age 16 (1.37, 95% CI, 1.22 to 1.53)), and a higher relative risk of not completing or being enrolled in upper secondary education by age 20 (1.05, 95% CI, 1.00 to 1.10). Haemoglobin A1c (HbA1c) <58 mmol/mol (7.5%), >7 BGM/day and insulin pump use were associated with better educational achievement. CONCLUSION Type 1 diabetes was associated with a marginally lower exam GPA and a higher risk of not completing compulsory school by age 16 and lower educational attainment by age 20. The findings were modified by HbA1c, BGM and insulin pump use.

Abstract
BACKGROUND Pre-gestational diabetes can pose significant risk to the mother and infant, thus requiring careful counselling and management. Since Saint Vincent's declaration in 1989, adverse maternal and fetal outcomes, such as preeclampsia, perinatal mortality, congenital anomalies, and macrosomia, continue to be associated with type 1 diabetes. Although pregnancy is not considered an independent risk factor for the development of new onset microvascular complications, it is known to exacerbate pre-existing microvascular disease. Strict glycaemic control is the optimal management for pre-existing type 1 diabetes in pregnancy, as raised HbA1C is associated with increased risk of maternal and fetal complications. More recently, time in range on Continuous Glucose Monitoring glucose profiles has emerged as another useful evidence-based marker of fetal outcomes. OBJECTIVES This review summarises the complications associated with pre-gestational type 1 diabetes, appropriate evidence-based management, including preparing for pregnancy, intrapartum and postpartum care. METHODS A structured search of the PubMed and Cochrane databases was conducted. Peer-reviewed articles about complications and management guidelines on pre-gestational type 1 diabetes were selected and critically appraised. RESULTS One hundred and twenty-three manuscripts were referenced and appraised in this review, and international guidelines were summarised. CONCLUSION This review provides a comprehensive overview of the recurring themes in the literature pertaining to type 1 diabetes in pregnancy: maternal and fetal complications, microvascular disease progression, and an overview of current guideline-specific management.

Abstract
Primary care providers (PCPs) play an important role in providing medical care for patients with type 2 diabetes. Advancements in diabetes technologies can assist PCPs in providing personalised care that addresses each patient's individual needs. Diabetes technologies fall into two major categories: devices for glycaemic self-monitoring and insulin delivery systems. Monitoring technologies encompass self-measured blood glucose (SMBG), where blood glucose is intermittently measured by a finger prick blood sample, and continuous glucose monitoring (CGM) devices, which use an interstitial sensor and are capable of giving real-time information. Studies show people using real-time CGM have better glucose control compared to SMBG. CGM allows for new parameters including time in range (the time spent within the desired target glucose range), which is an increasingly relevant real-time metric of glycaemic control. Insulin pens have increased the ease of administration of insulin and connected pens that can calculate and capture data on dosing are becoming available. There are a number of websites, software programs, and applications that can help PCPs and patients to integrate diabetes technology into their diabetes management schedules. In this article, we summarise these technologies and provide practical information to inform PCPs about utility in their clinical practice. The guiding principle is that use of technology should be individualised based on a patient's needs, desires, and availability of devices. Diabetes technology can help patients improve their clinical outcomes and achieve the quality of life they desire by decreasing disease burden.KEY MESSAGESIt is important to understand the role that diabetes technologies can play in primary care to help deliver high-quality care, taking into account patient and community resources. Diabetes technologies fall into two major categories: devices for glycaemic self-monitoring and insulin delivery systems. Modern self-measured blood glucose devices are simple to use and can help guide decision making for self-management plans to improve clinical outcomes, but cannot provide "live" data and may under- or overestimate blood glucose; patients' monitoring technique and compliance should be reviewed regularly. Importantly, before a patient is provided with monitoring technology, they must receive suitably structured education in its use and interpretation.Continuous glucose monitoring (CGM) is now standard of care for people with type 1 diabetes and people with type 2 diabetes on meal-time (prandial) insulin. Real-time CGM can tell both the patient and the healthcare provider when glucose is in the normal range, and when they are experiencing hyper- or hypoglycaemia. Using CGM data, changes in lifestyle, eating habits, and medications, including insulin, can help the patient to stay in a normal glycaemic range (70-180 mg/dL). Real-time CGM allows for creation of an ambulatory glucose profile and monitoring of time in range (the time spent within target blood glucose of 70-180 mg/dL), which ideally should be at least 70%; avoiding time above range (>180 mg/dL) is associated with reduced diabetes complications and avoiding time below range (<70 mg/dL) will prevent hypoglycaemia. Insulin pens are simpler to use than syringes, and connected pens capture information on insulin dose and injection timing.There are a number of websites, software programs and applications that can help primary care providers and patients to integrate diabetes technology into their diabetes management schedules. The guiding principle is that use of technology should be individualised based on a patient's needs, desires, skill level, and availability of devices.

Abstract
Type 1 diabetes (T1D) is a chronic life-threatening metabolic condition which needs to be accurately and continuously managed with care by multiple daily exogenous insulin injections, frequent blood glucose concentration monitoring, ad-hoc diet, and physical activity. In the last decades, new technologies, such as continuous glucose monitoring sensors, eased the burden for T1D patients and opened new therapy perspectives by fostering the development of decision support systems (DSS). A DSS for T1D should be able to provide patients with advice aimed at improving metabolic control and reducing the number of actions related to therapy handling. Major challenges are the vast intra-/inter-subject physiological variability and the many factors that impact glucose metabolism. The present work illustrates a new DSS for T1D management. The algorithmic core includes a module for optimal, personalized, insulin dose calculation and a module that triggers the assumption of rescue carbohydrates to avoid/mitigate impending hypoglycemic events. The algorithms are integrated within a prototype communication platform that comprises a mobile app, a real-time telemonitoring interface, and a cloud server to safely store patients' data. Tests made in silico show that the use of the new algorithms lead to metabolic control indices significantly better than those obtained by the standard care for T1D. The preliminary test of the prototype platform suggests that it is robust, performant, and well-accepted by both patients and clinicians. Future work will focus on the refinement of the communication platform and the design of a clinical trial to assess the system effectiveness in real-life conditions.Clinical Relevance- The presented DSS is a promising tool to facilitate T1D daily management and improve therapy efficacy.

Abstract
OBJECTIVE To provide evidence-based recommendations regarding the use of advanced technology in the management of persons with diabetes mellitus to clinicians, diabetes-care teams, health care professionals, and other stakeholders. METHODS The American Association of Clinical Endocrinology (AACE) conducted literature searches for relevant articles published from 2012 to 2021. A task force of medical experts developed evidence-based guideline recommendations based on a review of clinical evidence, expertise, and informal consensus, according to established AACE protocol for guideline development. MAIN OUTCOME MEASURES Primary outcomes of interest included hemoglobin A1C, rates and severity of hypoglycemia, time in range, time above range, and time below range. RESULTS This guideline includes 37 evidence-based clinical practice recommendations for advanced diabetes technology and contains 357 citations that inform the evidence base. RECOMMENDATIONS Evidence-based recommendations were developed regarding the efficacy and safety of devices for the management of persons with diabetes mellitus, metrics used to aide with the assessment of advanced diabetes technology, and standards for the implementation of this technology. CONCLUSIONS Advanced diabetes technology can assist persons with diabetes to safely and effectively achieve glycemic targets, improve quality of life, add greater convenience, potentially reduce burden of care, and offer a personalized approach to self-management. Furthermore, diabetes technology can improve the efficiency and effectiveness of clinical decision-making. Successful integration of these technologies into care requires knowledge about the functionality of devices in this rapidly changing field. This information will allow health care professionals to provide necessary education and training to persons accessing these treatments and have the required expertise to interpret data and make appropriate treatment adjustments.

Abstract
Fast-acting insulin aspart (faster aspart) is insulin aspart (IAsp) with two added excipients, l-arginine and niacinamide, to ensure formulation stability with accelerated initial absorption after subcutaneous administration compared with previously developed rapid-acting insulins. The pharmacokinetic/pharmacodynamic properties of faster aspart have been characterised in clinical pharmacology trials with comparable overall methodology. In subjects with type 1 (T1D) or type 2 (T2D) diabetes, the serum IAsp concentration–time and glucose-lowering effect profiles are left-shifted for faster aspart compared with IAsp. In addition, faster aspart provides earlier onset, doubling of initial exposure, and an up to 2.5-fold increase in initial glucose-lowering effect within 30 min of subcutaneous injection, as well as earlier offset of exposure and effect. Similar results have been shown using continuous subcutaneous insulin infusion (CSII). The improved pharmacological properties of faster aspart versus IAsp are consistent across populations, i.e. in the elderly, children, adolescents and the Japanese. Thus, the faster aspart pharmacological characteristics more closely resemble the mealtime insulin secretion in healthy individuals, giving faster aspart the potential to further improve postprandial glucose control in subjects with diabetes. Indeed, change from baseline in 1-h postprandial glucose increment is in favour of faster aspart versus IAsp when used as basal-bolus or CSII treatment in phase III trials in subjects with T1D or T2D. This review summarises the currently published results from clinical pharmacology trials with faster aspart and discusses the potential clinical benefits of faster aspart compared with previous rapid-acting insulin products.

Abstract
Technology has revolutionised our society. From the creation of the internet to smartphones and applications (apps), technology has changed how we communicate with each other, undertake regular tasks in our lives and access information at our fingertips. Technology has also transformed how we deliver healthcare with electronic patient records, more sensitive imaging modalities and newer treatments that are less invasive yet more cost-effective. The management of diabetes mellitus is an area that has kept pace with this revolution. With the emergence of a range of widely used technological options that can improve quality of life and metabolic outcomes, general physicians need to be aware of their application in diabetes, as well as how to manage acute diabetes presentations in people using these devices. This article aims to improve the knowledge that general physicians may have with diabetes technologies and guide them on the acute management in people using these technologies.

Abstract
This cross-sectional descriptive study aims to (1) describe the current digital technology (DT) use of people with chronic diseases (CD) by identifying different user profiles and (2) determine whether those profiles have specific characteristics regarding health-related variables and patient-doctor relationship quality (RQ). An online questionnaire assessing the uses of multiple types of DT (the Internet, mobile applications and connected devices) and several dimensions related to health and patient-doctor RQ was completed by 954 individuals living with CD. DT user groups were obtained by k-means cluster analysis and then compared using Mann-Whitney tests. The results show three profiles of DT users: (1) hyperconnected (8.9%, regular users of all DTs), (2) biconnected (19.1%, regular users of the Internet and mobile apps) and (3) hypoconnected (72%, casual users of the Internet only). The hyperconnected and biconnected groups are more empowered, more knowledgeable about their treatment and more committed to their doctors than the hypoconnected group. Nonadherence to treatment, health motivations, self-efficacy for health management and the trust dimension of the patient-doctor RQ did not differ between groups. We conclude by discussing the low use of the most recent technologies in the CD population, although these technologies seem to provide access to health information that empowers patients and leads to a better relationship with their doctors.

Abstract
Introduction: The aim of insulin replacement in insulin-deficient people (type 1 diabetes, pancreatic causes of diabetes, long-standing type 2 diabetes) is to approximate the physiologic insulin action profile as closely as possible. However, short-acting human insulins start too slow and act too long, causing postprandial hyperglycemia and delayed hypoglycemia, while the insulin action profile of long-acting human insulins is too variable in duration and strength of action, leading to insufficient basal insulin covering and peak insulin levels after injection causing early nocturnal hypoglycemia. Insulin analogues were designed to overcome these shortcomings. In insulin-resistant people (type 2 diabetes), insulin analogues contribute to more efficient and safer insulin supplementation. Areas covered: In this review, we describe the unmet needs for insulin therapy, the currently available short- and long-acting insulin analogues and some considerations on cardiovascular outcomes, use in special populations, and cost-effectiveness. Finally, we discuss what is new in the field of insulin analogues. Expert opinion: The development of insulin analogues is an important step in diabetes treatment. Despite many patients meeting their glycemic targets with the newest analogues, hypoglycemic episodes remain a major problem. More physiologic insulin regimens, with glucose-sensitive or organ-targeting insulin analogues may be the answer to these issues.

Abstract
Continuous subcutaneous insulin infusion (CSII) is a complex, medical device for the management of Type 1 Diabetes Mellitus (T1DM). There is limited research exploring the everyday experiences living with this device. The purpose of this study was to understand the lived experience of adults using CSII therapy to manage T1DM. Lived experiences from eight individuals were collected through semi-structured interviews and then analyzed using a hermeneutic approach to phenomenology. Four substantive themes with supporting subthemes were identified and represent the essence of participant experiences; that is, living with CSII eventually took ascendancy over managing T1DM.CSII therapy has gained popularity due to reported improvements in metabolic control and flexibility. However, the burden of the responsibility and psychological implications of CSII took ascendancy over T1DM. Living with CSII impacts the psychological well-being of individuals so psychological complications are as important to assess by healthcare professionals as physical and metabolic complications.

Abstract
Background: The use of insulin pump and glucose sensor is advantageous, but unfortunately many experience skin problems. To reduce or overcome skin problems, patients use additional products or change their sets preterm. Therefore, the aim was to investigate costs related to skin problems. Materials and Methods: Two hundred sixty-three patients from four different hospitals in Denmark participated in a cross-sectional survey about skin problems related to insulin pump and/or glucose sensor use. Additional costs aside technology and diabetes treatment were calculated based on adhesives, patches, lotion, and preterm shifts of infusion or sensor sets due to skin problems. Descriptive statistics and linear regression were used. Results: The total costs for all these expenses were 11493.9 U.S. dollars (USD) in 145 pediatric patients and 4843 USD in 118 adult patients. The costs were higher in patients with, than without, skin problems and for skin problems due to the glucose sensor compared with insulin pump. Pediatric patients with eczema and/or wound due to the glucose sensor did cost 154.3 USD more, than patients without these skin problems (P < 0.01). We found a clear dose/response relationship between costs and severity of skin problems, especially in pediatric patients. Conclusions: Our data show that skin problems due to use of insulin pump and/or glucose sensor have significant costs on the Danish welfare system. This leaves an economic incentive for developing more skin-sensitive adhesive for the infusion set and sensors, at least for a certain subgroup of patients.

Abstract
This paper presents a comprehensive survey about the fundamental components of the artificial pancreas (AP) system including insulin administration and delivery, glucose measurement (GM), and control strategies/algorithms used for type 1 diabetes mellitus (T1DM) treatment and control. Our main focus is on the T1DM that emerges due to pancreas’s failure to produce sufficient insulin due to the loss of beta cells (β-cells). We discuss various insulin administration and delivery methods including physiological methods, open-loop, and closed-loop schemes. Furthermore, we report several factors such as hyperglycemia, hypoglycemia, and many other physical factors that need to be considered while infusing insulin in human body via AP systems. We discuss three prominent control algorithms including proportional-integral- derivative (PID), fuzzy logic, and model predictive, which have been clinically evaluated and have all shown promising results. In addition, linear and non-linear insulin infusion control schemes have been formally discussed. To the best of our knowledge, this is the first work which systematically covers recent developments in the AP components with a solid foundation for future studies in the T1DM field.

Abstract
The pancreas is a visceral organ with exocrine functions for digestion and endocrine functions for maintenance of blood glucose homeostasis. In pancreatic diseases such as Type 1 diabetes, islets of the endocrine pancreas become dysfunctional and normal regulation of blood glucose concentration ceases. In healthy individuals, parasympathetic signaling to islets via the vagus nerve, triggers release of insulin from pancreatic β-cells and glucagon from α-cells. Using electrical stimulation to augment parasympathetic signaling may provide a way to control pancreatic endocrine functions and ultimately control blood glucose. Historical data suggest that cervical vagus nerve stimulation recruits many visceral organ systems. Simultaneous modulation of liver and digestive function along with pancreatic function provides differential signals that work to both raise and lower blood glucose. Targeted pancreatic vagus nerve stimulation may provide a solution to minimizing off-target effects through careful electrode placement just prior to pancreatic insertion.

Abstract
Optimal glycemic control remains challenging in individuals with type 1 diabetes. With the comprehensive clinical evidence on safety and efficiency, the adoption of continuous glucose monitoring (CGM), insulin pumps, and control algorithms merging the two into closed-loop systems is rapidly increasing. Particularly the CGM and intermittently scanned CGM improved diabetes management outcomes in large populations. A meaningful translation from clinical trials in highly controlled settings to numerous evaluations of closed-loop technology in the unrestricted home environment ended with its commercialization and use in routine clinical practice. Although it is still not a cure, the closed-loop currently seems to be the most promising advancement in the treatment of diabetes, with promising results also reported from routine clinical practice in children and adults with type 1 diabetes. We summarize different aspects of a technological approach to diabetes care, list currently available devices and systems in the pipeline, and the key supporting clinical evidence for their use. We consider human factors associated with technology use and the importance of health economics to support implementation and reimbursement.

Abstract
Diabetic ketoacidosis (DKA) is the most common acute hyperglycaemic emergency in people with diabetes mellitus. A diagnosis of DKA is confirmed when all of the three criteria are present - 'D', either elevated blood glucose levels or a family history of diabetes mellitus; 'K', the presence of high urinary or blood ketoacids; and 'A', a high anion gap metabolic acidosis. Early diagnosis and management are paramount to improve patient outcomes. The mainstays of treatment include restoration of circulating volume, insulin therapy, electrolyte replacement and treatment of any underlying precipitating event. Without optimal treatment, DKA remains a condition with appreciable, although largely preventable, morbidity and mortality. In this Primer, we discuss the epidemiology, pathogenesis, risk factors and diagnosis of DKA and provide practical recommendations for the management of DKA in adults and children.

Abstract
AIM To identify key psychosocial research in the domain of diabetes technology. RESULTS Four trajectories of psychosocial diabetes technology research are identified that characterize research over the past 25 years. Key evidence is reviewed on psychosocial outcomes of technology use as well as psychosocial barriers and facilitating conditions of diabetes technology uptake. Psychosocial interventions that address modifiable barriers and psychosocial factors have proven to be effective in improving glycaemic and self-reported outcomes in diabetes technology users. CONCLUSIONS Psychosocial diabetes technology research is essential for designing interventions and education programmes targeting the person with diabetes to facilitate optimized outcomes associated with technology uptake. Psychosocial aspects of diabetes technology use and related research will be even more important in the future given the advent of systems for automated insulin delivery and the increasingly widespread digitalization of diabetes care.

Abstract
Insulin infusion pump, continuous glucose monitoring (CGM), and insulin infusion set (IIS) have been developed to be increasingly feasible for people with type 1 diabetes (T1D). Several recently approved CGMs are transitioning from 7-day to 10-day wear time without the need for fingerprick recalibration. Nevertheless, studies and improvements on IIS, a critical part of insulin pump therapy, have been limited. In particular, the recommended wear time of IIS is still 2-3 days, which can hardly match the current duration of CGM for potential closed-loop system development. It is generally believed that both the inserted catheter and the subsequent infused insulin drug could induce particular subcutaneous tissue response and skin-related complications at the infusion site. In certain cases, poor glycaemic control, increased risk of hypoglycemia, and serious cosmetic impact on people with diabetes were observed. Skin complication has also been attributed as an important factor resulting users to discontinue insulin pump therapy. This article provides the rare systematic review of IIS induced subcutaneous tissue responses and skin complications, including the impacts from the inserted catheters, the subcutaneous infused insulin, and the adhesive or tape used to immobilize the catheter. The FDA's recommendation for the frequency of IIS change was further discussed. Future studies on this topic are required to further understand the IIS-related problems, and future strategies could be developed accordingly to significantly reduce the incidence of these problems, extend the wear time, and increase the acceptance of insulin pump based therapy.

Abstract
Technological innovations have fundamentally changed diabetes care. Insulin pump use and continuous glucose monitoring are associated with improved glycemic control along with a better quality of life; automated insulin-dosing advisors facilitate and improve decision making. Glucose-responsive automated insulin delivery enables the highest targets for time in range, lowest rate and duration of hypoglycemia, and favorable quality of life. Clear targets for time in ranges and a standard visualization of the data will help the diabetes technology to be used more efficiently. Decision support systems within and integrated cloud environment will further simplify, unify, and improve modern routine diabetes care.

Abstract
In the past few years, the increasing use of devices for diabetes treatment, such as continuous subcutaneous insulin infusion pumps, flash glucose monitoring, continuous glucose monitoring systems, sensor-augmented pumps, and automated insulin delivery devices, has resulted in important improvements in disease management. Meanwhile, the longer a patient uses a device, the greater the likelihood of developing a skin reaction. Allergic contact dermatitis is the most frequently described skin side effect caused by adhesive tapes contained in the insulin infusion sets or glucose sensor sets and used to connect these devices to the body. We describe 18 patients, followed up at our Pediatric Diabetes Centre, who experienced dermatological complications due to diabetes device use from January 2018 to December 2018. All the patients were patch tested with allergens from a "standard" series and from a "plastics and glues" series. Patch tests resulted positive in 66.7% of patients. Colophonium was the most frequently isolated sensitizing allergen (41.1% of cases). It is a complex mixture of >100 compounds derived from pine trees. Colophonium is commonly used, in both unmodified and modified forms, as a fast-acting adhesive for industrial, medical, or other commercial uses. Its presence in the adhesive of the insulin sets and glucose sensors was confirmed by the manufacturer of some devices brand. On the basis of our results, we stress the importance of contacting manufacturers for product information. We also highlight that there should be stricter legal restrictions to label medical adhesives, even if only small amounts of colophonium are used.

Abstract
AIM To conduct a meta-analysis to assess the effect of continuous subcutaneous insulin infusion (CSII), continuous glucose monitoring (CGM), and the combination of the two, on glycaemic control in type 2 diabetes. MATERIALS AND METHODS The analysis included randomized clinical trials comparing CSII with multiple daily injections (MDI) in people with type 2 diabetes, as well as studies comparing CGM or flash glucose monitoring (FGM) with self-monitoring of blood glucose (SMBG), with a duration of at least 12 weeks, identified in Medline or clinicaltrials.gov. The principal endpoint was glycated haemoglobin (HbA1c) at the end of the trial. Mean and 95% confidence intervals (CIs) for HbA1c and Mantel-Haenzel odds ratios for severe hypoglycaemia were calculated, using random-effect models. RESULTS The retrieved trials showed a significant heterogeneity (I2 = 90%). The difference in HbA1c between CSII and MDI was not statistically significant (-0.26% [95% CI -0.74;0.22]; P = .29). The difference in endpoint HbA1c between CGM and SMBG was marginally significant (-0.24 [95% CI -0.49;0.00]; P = .05), and CGM was possibly associated with a lower hypoglycaemic risk. Only one trial explored the effect of FGM, as compared with SMBG, on HbA1c in type 2 diabetes, finding no difference across groups (at study end: 8.4% ± 0.8% vs 8.3% ± 1.1% with FGM and SMBG, respectively). Conversely, FGM was associated with an improvement in quality of life and with a lower incidence of hypoglycaemic events. The small number of retrieved trials indicates that the results should be interpreted with caution. CONCLUSIONS The analysis showed that CSII, CGM and FGM provide only small benefits compared with MDI (on either HbA1c, hypoglycaemic risk or quality of life) in insulin-treated people with type 2 diabetes.

Abstract
OBJECTIVE Perioperative handling of insulin pumps (CSII) is inconsistent. The aims of this study were a literature search addressing this clinical question, analysis of data found and a proposal for perioperative management recommendations for clinical practice. METHODS A systematic search was conducted in PubMed and Clinical Research Network. RESULTS AND DISCUSSION A total of 11 publications on CSII in perioperative medicine were identified. According to the evidence CSII guarantees perioperative glycemic stability under certain clinical situations. The use of CSII could be continued in patients undergoing elective non-cardiac minor surgery with fasting for up to one meal only. International guidelines on surgery in diabetes do not address the use of perioperative CSII. There is no nationwide register data for CSII, the use of which could be around 18%. Based on the search results, a hospital internal protocol for perioperative management with CSII and patient information material were designed. CONCLUSION Growing evidence for improved patient outcome with perioperative CSII usage warrants interdisciplinary transfer of knowledge and experiences on intensified insulin therapy and patient empowerment.

Abstract
Meta-analyses of clinical trials comparing CSII with traditional insulin injections usually show a small, but significant advantage of CSII with respect to HbA1c and risk of severe hypoglycemia. On the other hand, CSII is associated with a small, but relevant risk of ketoacidosis, mainly due to malfunction of insulin pump and/or catheter occlusion. During last time, the technology of insulin pumps and infusion sets has improved as the profound evolution in type and schemes with traditional insulin injections. Aim of the present study is to update previous meta-analyses comparing CSII with traditional insulin injections in subjects with type 1 diabetes. Specific subgroup analyses were designed for assessing the effects of CSII in comparison with basal-bolus MDI, with short-acting analogues as bolus and long-acting analogues as basal insulin. In addition, an exploratory analysis was performed to verify the effect of CSII in insulin-naïve patients with type 1 diabetes. The present analysis includes all randomized clinical trials comparing CSII with traditional injections in type 1 diabetes, with a duration of at least 12 weeks. Animal studies were excluded, whereas no language or date restriction was imposed. If duplicate publications of a single trial were present, the paper containing more adequate information was considered as principal publication. In trials comparing CSII with basal-bolus MDI, performed before the introduction of rapid-acting analogues, regular human insulin was used for CSII, and as prandial insulin in control groups. CSII was associated with a significant reduction of A1c, in comparison with MDI, irrespective of the use of either human insulin or rapid-acting analogues. However, in trials with rapid-acting analogue the advantage of CSII was significantly smaller than in trials with regular human insulin (HbA1c difference: - 0.29[- 0.46; - 0.13] vs - 1.93[- 1.84; - 0.42]%; p = 0.02). Different rapid-acting analogues provided similar results (HbA1c reduction vs MDI: - 0.25 [- 0.48; - 0.02]%, p = 0.03, and - 0.29 [- 0.49; - 0.09]%, p = 0.005, for lispro and aspart, respectively). In addition, in trials comparing CSII with basal-bolus MDI, CSII reduced HbA1c to a similar extent irrespective of the use of either NPH or long-acting analogues as basal insulin in the control groups (HbA1c reduction vs MDI: - 0.31 [- 0.55; - 0.06]%, p = 0.01, and - 0.20 [- 0.38; - 0.03]%, p = 0.02, for NPH and long-acting analogues, respectively. With respect to severe hypoglycemia, CSII did not produce a significant reduction of risk in comparison with traditional insulin injections. Conversely, CSII was associated with a significant increase in the incidence of reported diabetic ketoacidosis (DKA). Notably, the increased risk of DKA was significant in trials comparing CSII with conventional insulin therapy, whereas only a nonsignificant trend toward an increased risk was observed in comparisons with basal-bolus MDI. Only two trials comparing CSII with basal-bolus MDI, both using rapid-acting analogues, were performed on insulin-naïve type 1 diabetic patients. When those two trials were analyzed separately, CSII did not produce any relevant effect on HbA1c (difference from control: - 0.10[- 0.38; + 0.17]%; p = 0.46). No meta-analysis could be performed on either severe hypoglycemia or DKA, which were not reported by one of the two trials. CSII seems to produce a small improvement in HbA1c in patients with type 1 diabetes inadequately controlled with MDI. This apparent effect, which could be partly due to publication bias, is smaller when MDI is properly performed using basal-bolus schemes with short-acting insulin analogues. Other outcomes different from HbA1c (such as quality of life) could be relevant for the choice of CSII instead of MDI. In addition, further studies are needed to better define the profile of patients who could benefit most from CSII.

Abstract
BACKGROUND The benefits and risks of continuous subcutaneous insulin infusion (CSII) or multiple daily injections (MDI) in patients with Type 1 diabetes mellitus (T1DM) who fast during Ramadan are not known. METHODS Systematic review and meta-analysis of observational studies conducted in PubMed, Embase (Ovid), and the Cochrane Library. Quality of included studies was assessed using the ROBINS-I tool for risk of bias assessment and analyses were performed using RevMan version 5.1. RESULTS From 709 records, 306 full text studies were assessed. After exclusions, the final analysis included a total of 9 studies. Heterogeneity for outcomes was I2 = 0%. There was no significant difference for the change in glycemic control (HbA1c) between CSII and MDI (P > 0.05). There was no change in weight or the lipid profile in patients with T1DM on MDI during Ramadan. There were insufficient data to assess the impact on glucose profiles and the incidence of hypoglycemia or diabetic ketoacidosis (DKA) in patients on CSII or MDI during Ramadan. CONCLUSIONS Studies assessing the effect of CSII or MDI in patients with T1DM who fast during Ramadan are limited to observational studies and show no difference in the change in HbA1c, weight or lipids during Ramadan.

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. FUNDING This project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 22, No. 42. See the NIHR Journals Library website for further project information. The cost of insulin pumps and consumables supplied by F. Hoffman-La Roche AG (Basel, Switzerland) for the purpose of the study were subject to a 25% discount on standard NHS costs.

Abstract
We investigated the pharmacodynamics (PD) and pharmacokinetics (PK) of BioChaperone insulin Lispro (BCLIS), faster insulin aspart (FIA) and insulin aspart (ASP) in patients with type 1 diabetes using an insulin pump. In this randomized, double-blind, three-way crossover glucose clamp study, 43 patients received a bolus dose of each insulin (0.15 U/kg) in addition to a basal rate (0.01 U/kg/h), delivered via an insulin pump. With BCLIS, the AUC-GIR,0-60 minutes (primary endpoint) was improved compared to ASP (least square means ratio, 1.63; 95% CI, 1.44-1.88; P < 0.0001) and was similar compared to FIA (least square means ratio, 1.06; 95% CI, 0.94-1.18; P = 0.4609). BCLIS showed faster-on PD (tearly0.5GIRmax ) than ASP and faster-off PD (tlate0.5GIRmax ) than both FIA and ASP. BCLIS also demonstrated significantly higher early exposure (AUCins, 0-60 minutes) and lower late exposure (AUCins,120-600 minutes) than both other insulins. In patients with type 1 diabetes using an insulin pump, BCLIS better mimics prandial insulin secretion and action than ASP and shows a faster off-PD than FIA.

Abstract
BACKGROUND In a 4-month follow-up survey, we examined whether treatment with continuous subcutaneous insulin infusion (CSII) and/or continuous glucose monitoring (CGM) in adults with type 1 diabetes was associated with sustained skin problems and whether skin problems were associated with diabetes-related emotional distress. RESEARCH DESIGN AND METHODS A total of 111 adult patients completed a follow-up questionnaire concerning skin problems as a result of CSII and/or CGM use. The questionnaire included a patient-reported outcome measure, the Problem Areas in Diabetes (PAID) scale. RESULTS Current visible skin problems caused by CSII or CGM use were reported by 51 (46.0%) participants, in 34 (66.7%) of whom skin problems had been reported more than 4 months earlier. Seventy-two (64.9%) participants reported skin problems as a result of CSII use, whereas 38 (74.5%) reported skin problems owing to CGM use at some time. Itching was the most prevalent complaint. CSII-related itching was associated with a mean PAID score >20 (P = 0.01), and patients with more than one skin problem had an increased PAID score compared with those with one or no skin problems (P = 0.006). CONCLUSIONS More than half patients treated with CSII, CGM, or both had experienced skin problems during 4 months of follow-up that were associated with increased diabetes burden. Skin problems represent a persistent health issue affecting diabetes-specific emotional distress.

Abstract
INTRODUCTION School-aged children with type 1 diabetes (DM1) require access to appropriate and safe care for their disease during their stay in the educational centre. OBJECTIVE To identify the needs perceived by families of schoolchildren with DM1 that affect their educational integration, safety, and well-being during the school day. METHODOLOGY A descriptive and cross-sectional study was conducted using a questionnaire based on information and opinions provided by families of 362 schoolchildren between 3 and 16 years old with DM1 registered in their health history in the Public Health System of Extremadura. RESULTS The response rate was 56.9% (206). It was shown that 35% of schoolchildren with DM1 were treated with continuous subcutaneous insulin infusion therapy. Almost all of them (95.1%) required glucose monitoring, and 57.8% required insulin administration during the school day. Most (88%) children had adjusted well to school and did not describe any type of discriminatory treatment (87.4%). Glucagon is available in 82% of educational centres, in which 43.7% had a trained adult person to administer it. That teachers could recognise a hypoglycaemia was expressed by 21.4% of the families, and 29.1% were unaware of the existence of coordination protocols in the school. More than half (58.7%) claimed that the information available in schools about diabetes was low, and 77.2% stated that the control of the disease would improve if more training was provided to teachers. CONCLUSIONS There are aspects optimally covered in the care of schoolchildren with DM1 in the schools of Extremadura. Among situations identified with potential room for improvement were adherence to the coordination protocol, information about diabetes, and training of adults to deal with emergency situations.

Abstract
OBJECTIVE To examine glycemic control in youth with type 1 diabetes (T1D) who switched from multiple daily injections (MDI) to a tubeless insulin pump (Omnipod Insulin Management System, Insulet Corporation, Billerica, Massachusetts) compared to patients who continued MDI therapy over a 3-year time period. RESEARCH DESIGN AND METHODS This retrospective analysis of the German/Austrian Diabetes Patienten Verlaufsdokumentation registry included data from 263 centers and 2529 patients <20 years (n = 660 tubeless insulin pump; n = 1869 MDI) who initiated treatment on a tubeless insulin pump as of January 1, 2013 and had 1 year of data preswitch from MDI and 3 years of data postswitch to a tubeless pump. Outcomes included the change in glycated hemoglobin (HbA1c), insulin dose, and body mass index (BMI) SD score (SDS). RESULTS Youth with T1D who switched from MDI therapy to a tubeless insulin pump showed better glycemic control at 1 year compared to patients who continued MDI treatment, adjusted mean ± SE: 7.5% ± 0.03% (58 mmol/mol) vs 7.7% ± 0.02% (61 mmol/mol); P < .001, with no between-group difference at 2 and 3 years. Total daily insulin dose was lower (P < .001) in the tubeless insulin pump group, 0.80 ± 0.01, 0.81 ± 0.01, and 0.85 ± 0.01 U/kg, vs the MDI group, 0.89 ± 0.01, 0.94 ± 0.01, and 0.97 ± 0.01 U/kg, at 1, 2, and 3 years, respectively (all P < .001). BMI SDS increased in both groups and was not different over time. CONCLUSIONS Treatment with a tubeless insulin pump in youth with T1D was associated with improvements in glycemic control compared to MDI after 1 year and appears to be an effective alternative to MDI.

Abstract
Use of insulin pump and glucose sensor in children with diabetes has been shown to cause skin problems such as eczema, wounds, and itching. The mechanisms for development of skin problems are unknown as well as the influence on the everyday life of the patient. The aim of this study was through focus groups to get more perspective on perception of skin problems as well as the patients' view on causes of skin problems. The two focus groups gave new insight into the consequences of skin problems to both patient and parents in terms of itching, concentration, self-esteem, guilt, etc. The focus group gave as well new perspectives on causes of skin problems, and especially three concepts must be further investigated: material (plastic, patch and vacuum effect), time, and skin characteristics.
