Abstract
BACKGROUND This analysis reports the findings from a predefined exploratory cohort (cohort B) from the ADAPT (ADvanced Hybrid Closed Loop Study in Adult Population with Type 1 Diabetes) study. Adults with type 1 diabetes (T1D) with suboptimal glucose control were randomly allocated to an advanced hybrid closed-loop (AHCL) system or multiple daily injections of insulin (MDI) plus real-time continuous glucose monitoring (RT-CGM). METHODS In this prospective, multicenter, exploratory, open-label, randomized controlled trial, 13 participants using MDI + RT-CGM and with HbA1c ≥8.0% were randomized to switch to AHCL (n = 8) or continue with MDI + RT-CGM (n = 5) for six months. Prespecified endpoints included the between-group difference in mean change from baseline in HbA1c, CGM-derived measures of glycemic control, and safety. RESULTS The mean HbA1c level decreased by 1.70 percentage points in the AHCL group versus a 0.60 percentage point decrease in the MDI + RT-CGM group, with a model-based treatment effect of -1.08 percentage points (95% confidence interval [CI] = -2.17 to 0.00 percentage points; P = .0508) in favor of AHCL. The percentage of time spent with sensor glucose levels between 70 and 180 mg/dL in the study phase was 73.6% in the AHCL group and 46.4% in the MDI + RT-CGM group; model-based between-group difference of 28.8 percentage points (95% CI = 12.3 to 45.3 percentage points; P = .0035). No diabetic ketoacidosis or severe hypoglycemia occurred in either group. CONCLUSIONS In people with T1D with HbA1c ≥8.0%, the use of AHCL resulted in improved glycemic control relative to MDI + RT-CGM. The scale of improvement suggests that AHCL should be considered as an option for people not achieving good glycemic control on MDI + RT-CGM.

Frequency of hypoglycaemia with basal insulin treatments in adults with type 1 diabetes treated with basal-bolus insulin regimens in treat-to-target trials: A narrative review. Diabet Med 2024; 41:e15339. [PMID: 38679910 DOI: 10.1111/dme.15339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 04/12/2024] [Accepted: 04/16/2024] [Indexed: 05/01/2024]
Abstract
AIM To summarise, in a narrative review, published data on hypoglycaemia occurrence with basal insulin therapy in adults with type 1 diabetes treated with basal-bolus insulin regimens in treat-to-target randomised controlled trials. METHODS Data were included from 21 eligible trials, which mainly used self-measured blood glucose or plasma glucose to detect hypoglycaemia. RESULTS All-day self-measured blood glucose or plasma glucose level 2 (glucose threshold of 3.1 or 3.0 mmol/L) and level 3 (severe, requiring assistance) hypoglycaemic events were reported, respectively, by a range of 69.0%-97.5% and 0%-13.4% adults when receiving basal-bolus insulin therapy, with rates of 10.6-68.1 and 0.0-0.4 events per patient-year of exposure, respectively. Hypoglycaemia rates measured using continuous glucose monitoring (three studies) were numerically, yet consistently, higher than with either other method, except when limiting to symptomatic events. Nocturnal hypoglycaemia rates were generally less than 30% of the equivalent all-day rates. CONCLUSIONS Differences across the studies in design (e.g., titration targets) and participant characteristics hindered comparison of hypoglycaemia rates by insulin formulation. Consequently, few trends were identified by insulin formulation, study methodology or individuals' characteristics, suggesting that further research is required to identify treatment strategies that facilitate development of individualised recommendations to lower hypoglycaemia risk. These findings are useful to understand hypoglycaemia risk with available basal insulin therapies when used in a multiple daily injection regimen, as well as to provide context for the results of ongoing and future clinical trials, including those for two once-weekly basal insulins, insulin icodec and basal insulin Fc.

Abstract
Introduction To describe the self-care challenges, diabetes technology awareness, current use, and satisfaction among adults with type 1 diabetes and parents of children with type 1 diabetes in Singapore. Methods An anonymous online survey was administered between November 2020 and October 2021. Data are presented as mean (standard deviation) or count (percentages). Comparisons between groups were done using the independent samples T-test. Results 251 people (176 adults, 75 parents) participated. The most challenging self-care burdens were carbohydrate counting (24.4%) among adults and insulin dose calculations (28%) among parents. Nocturnal awakenings for diabetes care of their child were a common event (25.3%). Despite high awareness about continuous glucose monitoring devices (77.8% adults, 78.7% parents) the use (24.9% adults, 55% children) remained low. Both adults and parents of children with type 1 diabetes found continuous glucose monitoring to be liberating and less restrictive. Despite overall low insulin pump use (23.9% adults, 29.3% children); satisfaction scores were higher among insulin pump users than insulin pen users (P = 0.02). Conclusion Carbohydrate counting and insulin dose calculations were the most challenging self-care tasks among people with type 1 diabetes in Singapore. Diabetes technology use was relatively low in Singapore. Continuous glucose monitoring and Insulin pump users found them to be beneficial.

Pham DQ, Thorsell A, Castorino K, Cobb B. A review of CONCEPTT study findings including subanalyses in pregnant women using continuous glucose monitoring with type 1 diabetes and their offspring. Endocr Connect 2024; 13:e230407. [PMID: 38010170 PMCID: PMC10831538 DOI: 10.1530/ec-23-0407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 11/27/2023] [Indexed: 11/29/2023]
Abstract
The main objective of this article is to provide a comprehensive review of continuous glucose monitor (CGM) use in pregnant women with type 1 diabetes (T1D) from the CONCEPTT study including subanalyses. Literature search was accessed through MEDLINE (1966-September 2023) using the key terms: CONCEPTT, pregnancy, women, T1D, and CGM with limitations set to distinguish human subjects written in English. A total of 17 publications including one main clinical trial and 15 subanalyses have been published to date regarding the use of CGM in pregnant women with T1D which were conducted by a research group identified as the CONCEPTT Collaborative Group. While advances in maternal care have resulted in safer pregnancy for both the mother and child, women with preexisting T1D and pregnancy still experience higher rates of complications both in the short and long term. The use of CGM in pregnancy has not been studied extensively until more recently. The CONCEPTT clinical trial was a landmark study that involved several subanalyses. The main trial proved that CGM use in T1D pregnancy resulted in less hyperglycemia in the third trimester, reduced large for gestational age (LGA, >90th percentile), reduced neonatal intensive care unit admissions lasting longer than 24 h, and reduced neonatal hypoglycemia. Although subanalyses showed a variety of results including 'inconclusive' due to lack of prespecification, it is believed that CGM in T1D during pregnancy is to be recommended and used for overall improved outcomes.

Abstract
BACKGROUND Advances in treatment could mitigate the expected adverse changes in the body composition of children and adolescents with type 1 diabetes (T1D). OBJECTIVES To examine the evolution of weight status and body composition and their association with glycaemic control and partial clinical remission in youth with T1D. METHODS Ninety-nine participants with T1D (median age 9.5 years [interquartile range 7.3, 12.9], 59.6% boys) were longitudinally followed for 3 years since diagnosis. Data at seven pre-determined time points were extracted from medical files. Outcome measures included body mass index (BMI) z-scores, muscle-to-fat ratio (MFR) z-scores, haemoglobin A1c (HbA1c) levels, continuous glucose monitoring metrics, and insulin dose-adjusted HbA1c (IDAA1c) levels. RESULTS The BMI z-scores increased significantly (p < 0.001) for both sexes, with no significant change in MFR z-scores over time. The girls had higher BMI z-scores (p < 0.001) and lower MFR z-scores than the boys (p = 0.016). The mean HbA1c levels decreased during the first month and at 3 months since diagnosis (p < 0.001), then plateaued and achieved a median overall HbA1c of 7.1% for the entire cohort. At 12 months, 37 participants (37.6%) were in partial clinical remission, as evidenced by IDAA1c ≤ 9. The odds of partial clinical remission at 2 years increased by 2.1-fold for each standard deviation increase in the MFR z-score (p < 0.001). Higher MFR z-scores were associated with better metabolic control. CONCLUSIONS Integration of body composition assessments could mitigate adverse body changes in paediatric patients with T1D.

Abstract
OBJECTIVES Technology use has been shown to improve diabetes control, but minority youths tend to have low rates of technology use and exhibit suboptimal glycemic control. We examined the impact of continuous glucose monitors (CGM) and continuous subcutaneous insulin infusion (CSII) on glycemic control in a racial-ethnic minority cohort of children and adolescents with type 1 diabetes (T1D). METHODS A cross-sectional study was conducted among 140 pediatric T1D patients seen at a multidisciplinary clinic. From January to November 2022, data on demographics and glycated hemoglobin (HbA1c) levels were collected. Patients were categorized as technology (CGM, CSII, or both) or non-technology users (finger stick meter (FS) and multiple daily injections (MDI)). RESULTS The majority identified as Hispanic (79 %) and had public health insurance (71 %). Sixty-nine percent used technology. Compared with non-technology users, technology users had significantly lower mean HbA1c levels (9.60 vs. 8.40 %, respectively) (p=0.0024), though no group (CGM + CSII, CGM + MDI, FS + CSII, and FS + MDI) achieved a mean HbA1c level of <7.0 %. Regarding minority status, no significant differences in mean HbA1c levels existed between Hispanics and Blacks in the CGM + MDI and FS + CSII groups (p=0.2232 and p=0.9224, respectively). However, there was a significant difference in mean HbA1c levels between Hispanic and Black non-technology users (9.19 vs. 11.26 %, respectively) (p=0.0385). CONCLUSIONS Technology users demonstrated better glycemic control than non-technology users. Further research is needed to investigate factors affecting glycemic control in minority youths with T1D.

Abstract
BACKGROUND Pancreas transplant is the only treatment that establishes normal glucose levels for patients diagnosed with diabetes. However, since 2005, no comprehensive analysis has compared survival outcomes of: (1) Simultaneous pancreas-kidney (SPK) transplant; (2) Pancreas after kidney (PAK) transplant; and (3) Pancreas transplant alone (PTA) to waitlist survival.
AIM To explore the outcomes of pancreas transplants in the United States during the decade 2008-2018.
METHODS Our study utilized the United Network for Organ Sharing Standard Transplant Analysis and Research file. Pre- and post-transplant recipient and waitlist characteristics and the most recent recipient transplant and mortality status were used. We included all patients with type I diabetes listed for pancreas or kidney-pancreas transplant between May 31, 2008 and May 31, 2018. Patients were grouped into one of three transplant types: SPK, PAK, or PTA.
RESULTS The adjusted Cox proportional hazards models comparing survival between transplanted and non-transplanted patients in each transplant type group showed that patients who underwent an SPK transplant exhibited a significantly reduced hazard of mortality [hazard ratio (HR) = 0.21, 95% confidence intervals (CI): 0.19-0.25] compared to those not transplanted. Neither PAK transplanted patients (HR = 1.68, 95%CI: 0.99-2.87) nor PTA patients (HR = 1.01, 95%CI: 0.53-1.95) experienced significantly different hazards of mortality compared to patients who did not receive a transplant.
CONCLUSION When assessing each of the three transplant types, only SPK transplant offered a survival advantage compared to patients on the waiting list. PKA and PTA transplanted patients demonstrated no significant differences compared to patients who did not receive a transplant.

Abstract
OBJECTIVE The overall purpose of this study was to explore adolescent perspectives on communicating about self-management of type 1 diabetes (T1D) and negotiating responsibilities for self-management with parents. METHODS Semi-structured interviews were conducted with 28 adolescents aged 11-17 years living with T1D. Interviews were audio-recorded, transcribed verbatim and thematically analysed. RESULTS Two themes and five subthemes were identified. The first theme, 'changing levels of involvement in self-management' describes the division of responsibility for self-management within the family and adolescents collaborating and sharing responsibilities with parents for self-management. The second theme, 'talking about self-management with parents' describes changes in patterns of parent-adolescent communication about T1D over time, adolescents' seeking parental feedback and advice and the factors that contribute to the promotion of self-management communication between adolescents and parents. CONCLUSION This study identified that how adolescents perceive communication with their parents contributes to negotiation of responsibilities for self-management during adolescence. The findings provide a nuanced understanding of adolescent perspectives on communication with parents about T1D self-management and how parent-adolescent communication can be framed in ways that promote positive adolescent engagement with T1D self-management. PRACTICE IMPLICATIONS Targeting parent-adolescent communication strategies may result in more optimal sharing of responsibilities and improved self-management.

Abstract
AIMS Type 1 diabetes has been associated with a significant reduction in life expectancy. Major advances in treatment of type 1 diabetes have been associated with improved survival. However, life expectancy for type 1 diabetes under contemporary care is not known. METHODS Health care registers were used to obtain data on all people with type 1 diabetes in Finland in 1964-2017 and their mortality in 1972-2017. Survival analyses were used to study long-term trends in survival and abridged period life table methods to calculate life expectancy estimates. Causes of death were examined to consider development. RESULTS Study data included 42,936 persons with type 1 diabetes and 6,771 deaths. Kaplan-Meier curves showed improved survival during the study period. In 2017, the remaining life expectancy at the age of 20 for a person diagnosed for type 1 diabetes was estimated to be 51.64 (95% CI: 51.51, 51.78) years which was 9.88 (9.74, 10.01) years lower than for the general Finnish population. CONCLUSIONS We found improved survival among persons with type 1 diabetes during the last decades. However, their life expectancy remained significantly below that of the general Finnish population. Our results call for further innovations and improvements in diabetes care.

Abstract
Over the past decade there have been many advances in diabetes technologies, such as continuous glucose monitors (CGM s), insulin-delivery devices, and hybrid closed loop systems . Now most CGMs (Medtronic-Guardian, Dexcom-G6, and Abbott-Libre-2) have MARD values of < 10%, in contrast to two decades ago when the MARD used to be > 20%. In addition, the majority of the new CGMs do not require calibrations, and the latest CGMs last for 10-14 days. An implantable 6-months CGM by Eversense-3 is now approved in the USA and Europe. Recently, the FDA approved Libre 3 which provides real-time glucose values every minute. Even though it is approved as an iCGM it is not interoperable with automatic-insulin-delivery (AID) systems. The newer CGMs that are likely to be launched in the next few months in the USA include the 10-11 days Dexcom G7 (60% smaller than the existing G6), and the 7-days Medtronic Guardian 4. Most of the newer CGM have several features like automatic initialization, easy insertion, predictive alarms, and alerts. It has also been noticed that an arm insertion site might have better accuracy than abdomen or other sites, like the buttock for kids. Lag time between YSI and different sensors have been reported differently, sometimes it is down to 2-3 min; however, in many instances, it is still 15-20 min, especially when the rate of change of glucose is > 2 mg/min. We believe that in the next decade there will be a significant increase in the number of people who use CGM for their day-to-day diabetes care.

[PMID: 35303080 PMCID: PMC9297080 DOI: 10.1093/jpepsy/jsac019] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 02/24/2022] [Accepted: 02/27/2022] [Indexed: 01/02/2023] Open
Abstract
OBJECTIVE Friendships and romantic relationships are important sources of support that contribute to well-being for youth across adolescence and emerging adulthood and may be especially important for those with a chronic illness. We examined gender differences in trajectories of peer relationships among those with type 1 diabetes (T1D) and how they differ from those without. METHODS Individuals with T1D (N = 132) and controls (N = 131) completed questionnaires across 11 years (M age = 12 years at baseline). Trajectories of friend support, conflict, and companionship were estimated from ages 11 to 23. Romantic support and conflict trajectories were estimated from ages 17 to 23. RESULTS Females experienced more friend support than males, especially in comparison to males with T1D. Control females experienced highest levels of romantic support and lowest levels of romantic conflict. In comparison to control males, males with T1D experienced less friend support in early adolescence and less companionship in late adolescence and emerging adulthood. In comparison to control females, females with T1D experienced less friend support in late adolescence and more romantic conflict in emerging adulthood. CONCLUSIONS Findings that males with T1D report less friend support and companionship compared to control males, and females with T1D report less friend support and more romantic conflict than control females are of concern as these results suggest those with T1D may be missing out on important aspects of peer relationships. Understanding the broader social network of peer relationships may be useful to clinicians as they assist individuals in garnering support in general and for their diabetes.

Abstract
OBJECTIVE Diabetes distress (DD) is a negative emotional response related to the burdens of living with type 1 diabetes (T1D) and is linked with diabetes outcomes, such as hemoglobin A1c (A1c). Yet, less is known about how other glycemic indicators, average blood glucose and time in range, relate to DD, and which demographic characteristics are associated with higher DD. METHODS In total, 369 teens (Mage 15.6 ± 1.4, 51% female, MT1D duration 6.7 ± 3.8 years) screened for DD using The Problem Areas in Diabetes-Teen Version to determine eligibility for an ongoing multi-site behavioral trial. The associations of DD, demographic factors, and glycemic indicators (A1c, average blood glucose, and time in range) were analyzed. RESULTS Twenty-nine percent of teens (n = 95) scored above the clinical cutoff (≥44) for DD. Females scored significantly higher on average than males. Black/African American, non-Hispanic youth screened significantly higher compared to youth from other racial/ethnic groups. Higher DD scores were related to higher A1c and average blood glucose, and lower time in range. Logistic regression models revealed that females were significantly more likely to report clinically elevated DD than males, and teens with higher A1c were 1.3 times more likely to report DD. Age and diabetes duration were not significantly associated with clinically elevated DD scores. CONCLUSIONS Results demonstrated that DD is most prevalent in Black, non-Hispanic and female teens, and DD is associated with higher average blood glucose and lower time in range. Further investigation into these disparities is warranted to promote optimal health outcomes for teens with T1D.

Abstract
As continuous glucose monitoring (CGM) sensors generate ever increasing amounts of CGM data, the need for methods to simplify the storage and analysis of this data becomes increasingly important. Lobo et al. developed a classifier of daily CGM profiles as an initial step in addressing this need. The classifier has several important applications including, but not limited to, data compression, data encryption, and indexing of databases. While the classifier has already successfully classified 99.0% of the 42,595 daily CGM profiles in a Test Set, this work presents an external validation using an external validation set (EVal Set) derived from 8 publicly available data sets. The Test Set and the EVal Set differ in terms of (but not limited to) demographics, data collection time periods, and data collection geographies. The classifier successfully classified 98.2% of the 137,030 daily CGM profiles in the EVal Set. Furthermore, each of the 483 distinct groups of classified daily CGM profiles from the EVal Set retains the same clinical characteristics as the corresponding group from the Test Set, as desired. Finally, the set of unclassified daily CGM profiles from the EVal Set retains the same statistical characteristics as the set of unclassified daily CGM profiles from the Test Set, as desired. These results establish the robustness and generalizability of the classifier: the performance of the classifier is unchanged despite the marked differences between the Test Set and the EVal Set.

J Biochem Mol Toxicol 2022; 36:e23004.

Abstract
Saponin gypenoside A (GP) has shown its potential to handle diabetes mellitus. MicroRNA-150-3p (miR-150-3p) is closely related to the dysfunction of pancreatic β cells by targeting PDX1. Given the function of GP is related to its regulation on different miRs, the current study assessed the role of miR-150-3p as a therapeutic target for the hypoglycemic effects of GP. Pancreatic β cell dysfunction was induced in mice using the high-fatty diet (HFD) method and then handled with GP. Changes in insulin release and resistance and the activity of the miR-150-3p/PDX1 axis were detected. The expression of miR-150-3p was induced to confirm its central in the effects of GP. The results of in vivo tests were then validated with in vitro assays. HFD administration suppressed glucose tolerance, delayed insulin release, and induced insulin resistance and pancreas apoptosis in mice, which was indicative of the dysfunction of β pancreatic cells. Changes in pancreatic β function were associated with the increased expression of miR-150-3p and suppressed expression of PDX1. After the administration of GP, the impairments of the pancreas were alleviated and the expression of miR-150-3p was inhibited, contributing to the restored level of PDX1. The injection of miR-150-3p agomir counteracted the protective effects of GP. In in vitro assays, the pretransfection of miR-150-3p mimetics also counteracted the protective effects of GP on pancreatic β cells against palmitic acid. Collectively, miR-150-3p played a key role in the protective effects of GP against pancreatic β cell dysfunction by inhibiting PDX1 expression.

Abstract
BACKGROUND Optimum glycemic control is necessary to reduce and even prevent the risk of micro- and macrovascular complications of type 1 diabetes mellitus (T1DM). The main aim of this study was to assess the prevalence of T1DM patients with adequate glycemic control in 4 Arabian Gulf countries. METHODS This study was a multicenter, observational, cross-sectional disease registry. Data were collected from adult T1DM patients who were treated with insulin within 6 months prior to the study visit. RESULTS Out of 241 patients whose data were eligible for primary endpoint analysis, 27.4% had adequate glycemic control (HbA1c < 7%). The patients' age ranged from 18 to 64 years, and 53% were males. The mean (SD) duration of diabetes was 14.6 (9) years and the mean HbA1c was 8.11 (1.8) %. At the time of T1DM diagnosis, mean HbA1c was 10.7 (2.17) %. About 98% of the patients were normotensive and the lipid profile of patients was found to be optimal. The main variables associated with adequate glycemic control were low HbA1c at diagnosis (P < 0.001) and absence of a family history of diabetes (P = 0.002). CONCLUSIONS We found that the glycemic control of T1DM adult patients in Kuwait, UAE, Oman and Bahrain is suboptimal. More efforts are necessary to pinpoint the causes of inadequate control in this population.

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
BACKGROUND There are several medical devices used in Colombia for diabetes management, most of which have an associated telemedicine platform to access the data. In this work, we present the results of a pilot study evaluating the use of the Tidepool telemedicine platform for providing remote diabetes health services in Colombia across multiple devices. METHOD Individuals with Type 1 and Type 2 diabetes using multiple diabetes devices were recruited to evaluate the user experience with Tidepool over three months. Two endocrinologists used the Tidepool software to maintain a weekly communication with participants reviewing the devices data remotely. Demographic, clinical, psychological and usability data were collected at several stages of the study. RESULTS Six participants, from ten at the baseline (five MDI and five CSII), completed this pilot study. Three different diabetes devices were employed by the participants: a glucose meter (Abbot), an intermittently-scanned glucose monitor (Abbot), and an insulin pump (Medtronic). A score of 81.3 in the system usability scale revealed that overall, most participants found the system easy to use, especially the web interface. The system also compared highly favourably against the proprietary platforms. The ability to upload and share data and communicate remotely with the clinicians was raised consistently by participants. Clinicians cited the lockdown imposed by the Covid-19 pandemic as a valuable test for this platform. Inability to upload data from mobile devices was identified as one of the main limitations. CONCLUSION Tidepool has the potential to be used as a tool to facilitate remote diabetes care in Colombia. Users, both participants and clinicians, agreed to recommend the use of platforms like Tidepool to achieve better disease management and communication with the health care team. Some improvements were identified to enhance the user experience.

Abstract
Medical devices and medicinal products have many similarities in their nature, scope or specific medical purposes, and despite the differences in their principal means of action, they are often used in combination. Indeed, many medicinal products depend on medical devices for their administration, and it is increasingly common for medical devices to contain medicinal substances to support their action. Therefore, the combination of medicinal products and medical devices provides additional benefits for patients. However, their higher technical complexity requires a strengthening of their authorisation and certification requirements. In this regard, more comprehensive requirements and classification rules are introduced by a new European regulation on medical devices that fully applies from May 26th 2021. On account of their therapeutic significance, this review aims at gaining insight into the borderline between medical devices and medicinal products in this new 2021 regulatory framework. For the first time, any item containing a medical device and a medicinal product will have both parts evaluated. Through exemplification of both marketed and investigational devices incorporating medicinal substances and drug-device combinations, the new European requirements and their implications are thoroughly illustrated herein.

Abstract
The pathophysiology of takotsubo syndrome (TTS) is elusive. Heightened adrenergic surge via the sympathetic nervous system (mainly by norepinephrine secretion) and/or elevated blood-borne catecholamines (mainly epinephrine, secreted by the adrenals) probably mediate TTS. Patients with TTS have a low prevalence of diabetes mellitus (DM), and it has been postulated that DM, via its associated neuropathy, prevents the emergence of TTS. Insulin, in animal experiments, has been shown to greatly attenuate the effects of NE on the cardiomyocytes; also, insulin in a limited clinical experience, has been found to improve heart function in patients with neurogenic stress-cardiomyopathy and TTS. Accordingly, it is postulated that high levels of insulin encountered in patients with type 2 DM are at the roots of the protective effect of DM for the emergence of TTS. Thus, a role of insulin in the pathophysiology, diagnosis, prognosis, and therapy of TTS appears to be plausible, and needs exploration.

Abstract
Artificial pancreas system (APS) is an emerging new treatment for type 1 diabetes mellitus. The aim of this study was to develop a rat APS as a research tool and demonstrate its application. We established a rat APS using Medtronic Minimed Pump 722, Medtronic Enlite sensor, and the open artificial pancreas system as a controller. We tested different dilutions of Humalog (100 units/ml) in saline ranged from 1:3 to 1:20 and determined that 1:7 dilution works well for rats with ~500g bodyweight. Blood glucose levels (BGL) of diabetic rats fed with chow diet (58% carbohydrate) whose BGL was managed by the closed-loop APS for the total duration of 207h were in euglycemic range (70-180 mg/dl) for 94.5% of the time with 2.1% and 3.4% for hyperglycemia (>180mg/dl) and hypoglycemia (<70 mg/dl), respectively. Diabetic rats fed with Sucrose pellets (94.8% carbohydrate) for the experimental duration of 175h were in euglycemic range for 61% of the time with 35% and 4% for hyperglycemia and hypoglycemia, respectively. Heathy rats fed with chow diet showed almost a straight line of BGL ~ 95 mg/dl (average 94.8 mg/dl) during the entire experimental period (281h), which was minimally altered by food intake. In the healthy rats, feeding sucrose pellets caused greater range of BGL in high and low levels but still within euglycemic range (99.9%). Next, to study how healthy and diabetic rats handle supra-physiological concentrations of glucose, we intraperitoneally injected various amounts of 50% dextrose (2, 3, 4g/kg) and monitored BGL. Duration of hyperglycemia after injection of 50% dextrose at all three different concentrations was significantly greater for healthy rats than diabetic rats, suggesting that insulin infusion by APS was superior in reducing BGL as compared to natural insulin released from pancreatic β-cells. Ex vivo studies showed that islets isolated from diabetic rats were almost completely devoid of pancreatic β-cells but with intact α-cells as expected. Lipid droplet deposition in the liver of diabetic rats was significantly lower with higher levels of triacylglyceride in the blood as compared to those of healthy rats, suggesting lipid metabolism was altered in diabetic rats. However, glycogen storage in the liver determined by Periodic acid-Schiff staining was not altered in diabetic rats as compared to healthy rats. A rat APS may be used as a powerful tool not only to study alterations of glucose and insulin homeostasis in real-time caused by diet, exercise, hormones, or antidiabetic agents, but also to test mathematical and engineering models of blood glucose prediction or new algorithms for closed-loop APS.

Abstract
Background: In contrast to type 2 diabetes, type 1 diabetes mellitus (T1DM) requires insulin treatment to control blood glucose. As the incidence and prevalence of T1DM have steadily increased; therefore, T1DM is increasingly being diagnosed not only in children and adolescents, but also in adults. Therefore, the importance of accurate diagnosis and optimal management of T1DM is being recognized in clinical practice.Current Concepts: T1DM is caused by insulin deficiency, following the destruction of insulin-producing pancreatic β-cells. Diagnosis of diabetes is based on the following criteria: fasting blood glucose levels ≥126 mg/dL, random blood glucose levels ≥200 mg/dL accompanied by symptoms of hyperglycemia, an abnormal 2-hour oral glucose tolerance test, or glycated hemoglobin ≥6.5%. Accurate diagnosis of T1DM based on patients’ clinical characteristics, serum C-peptide levels, and detection of autoantibodies against β-cell autoantigens is important for optimum care and to avoid complications. A target glycated hemoglobin level is recommended in children, adolescents, and young adults with access to comprehensive care. The availability of insulin analogues and mechanical technologies (insulin pumps and continuous glucose monitors) has improved the management of T1DM, and these are useful for the prevention of microvascular complications. Screening for microvascular complications should commence at puberty or 5 years after diagnosis of T1DM.Discussion and Conclusion: Effective cooperation and coordination between patient, parents, and healthcare providers are necessary to achieve a successful transition from pediatric to adult care in patients with T1DM. Diabetic management for T1DM should be individualized based on patients’ lifestyle, as well as psychosocial, and medical circumstances.

Abstract
Insulin replacement therapy for diabetes mellitus seeks to minimise excursions in blood glucose concentration above or below the therapeutic range (hyper- or hypoglycaemia). To mitigate acute and chronic risks of such excursions, glucose-responsive insulin-delivery technologies have long been sought for clinical application in type 1 and long-standing type 2 diabetes mellitus. Such 'smart' systems or insulin analogues seek to provide hormonal activity proportional to blood glucose levels without external monitoring. This review highlights three broad strategies to co-optimise mean glycaemic control and time in range: (1) coupling of continuous glucose monitoring (CGM) to delivery devices (algorithm-based 'closed-loop' systems); (2) glucose-responsive polymer encapsulation of insulin; and (3) mechanism-based hormone modifications. Innovations span control algorithms for CGM-based insulin-delivery systems, glucose-responsive polymer matrices, bio-inspired design based on insulin's conformational switch mechanism upon insulin receptor engagement, and glucose-responsive modifications of new insulin analogues. In each case, innovations in insulin chemistry and formulation may enhance clinical outcomes. Prospects are discussed for intrinsic glucose-responsive insulin analogues containing a reversible switch (regulating bioavailability or conformation) that can be activated by glucose at high concentrations.

Diabetes-specific friend support in emerging adults with type 1 diabetes: Does satisfaction with support matter? J Behav Med 2021; 44:402-411. [PMID: 33677767 DOI: 10.1007/s10865-021-00211-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 02/19/2021] [Indexed: 01/24/2023]
Abstract
Youth with type 1 diabetes (T1D) must adhere to a complex treatment regimen to prevent health complications. Friends may provide diabetes-specific support to help youth manage diabetes, but evidence on whether youth benefit from diabetes-specific friend support is inconclusive. The present study first investigated whether satisfaction with friend support was linked to psychological distress and diabetes management. Second, it was investigated whether self-esteem mediated these relations. To this end, 324 Dutch-speaking emerging adults (17-28 years) with T1D completed questionnaires on diabetes-specific friend support, self-esteem, diabetes-specific distress, depressive symptoms, and self-care. HbA1c values were obtained from patients' physicians. Receiving diabetes-specific support from friends was associated with more diabetes-specific distress, but not for youth who were satisfied with the received support. Diabetes-specific friend support was not associated with other outcomes. Self-esteem did not mediate these relations. These results suggest that associations between diabetes-specific friend support and diabetes management are limited and that support satisfaction should be taken into consideration when examining the role of friend support for youth with T1D.

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.
