Glucose monitoring has evolved from self-monitoring of blood glucose to glycated hemoglobin, and the latest continuous glucose monitoring (CGM). A key challenge to adoption of CGM for management of diabetes in Asia is the lack of regional CGM recommendations. Hence, thirteen diabetes-specialists from eight Asia-Pacific (APAC) countries/regions convened to formulate evidence-based, APAC-specific CGM recommendations for individuals with diabetes. We defined CGM metrics/targets and developed 13 guiding-statements on use of CGM in: (1) people with diabetes on intensive insulin therapy, and (2) people with type 2 diabetes on basal insulin with/without glucose lowering drugs. Continual use of CGM is recommended in individuals with diabetes on intensive insulin therapy and suboptimal glycemic control, or at high risk of problematic hypoglycemia. Continual/intermittent CGM may also be considered in individuals with type 2 diabetes on basal insulin regimen and with suboptimal glycemic control. In this paper, we provided guidance for optimizing CGM in special populations/situations, including elderly, pregnancy, Ramadan-fasting, newly diagnosed type 1 diabetes, and comorbid renal disease. Statements on remote CGM, and stepwise interpretation of CGM data were also developed. Two Delphi surveys were conducted to rate the agreement on statements. The current APAC-specific CGM recommendations provide useful guidance for optimizing use of CGM in the region.

A technological solution for the management of diabetes in people who require intensive insulin therapy has been sought for decades. The last 10 years have seen substantial growth in devices that can be integrated into clinical care. Driven by the availability of reliable systems for continuous glucose monitoring, we have entered an era in which insulin delivery through insulin pumps can be modulated based on sensor glucose data. Over the past few years, regulatory approval of the first automated insulin delivery (AID) systems has been granted, and these systems have been adopted into clinical care. Additionally, a community of people living with type 1 diabetes has created its own systems using a do-it-yourself approach by using products commercialized for independent use. With several AID systems in development, some of which are anticipated to be granted regulatory approval in the near future, the joint Diabetes Technology Working Group of the European Association for the Study of Diabetes and the American Diabetes Association has created this consensus report. We provide a review of the current landscape of AID systems, with a particular focus on their safety. We conclude with a series of recommended targeted actions. This is the fourth in a series of reports issued by this working group. The working group was jointly commissioned by the executives of both organizations to write the first statement on insulin pumps, which was published in 2015. The original authoring group was comprised by three nominated members of the American Diabetes Association and three nominated members of the European Association for the Study of Diabetes. Additional authors have been added to the group to increase diversity and range of expertise. Each organization has provided a similar internal review process for each manuscript prior to submission for editorial review by the two journals. Harmonization of editorial and substantial modifications has occurred at both levels. The members of the group have selected the subject of each statement and submitted the selection to both organizations for confirmation.

Continuous glucose monitoring (CGM) systems are increasingly being adopted as an alternative or adjunct to self-monitoring of blood glucose (SMBG) by patients receiving insulin therapy. However, the available evidence on the role of intermittently scanned CGM or flash CGM (isCGM) remains limited. This consensus aims to evaluate the degree of agreement among Spanish experts on the role of isCGM in the evaluation of glycemic variability, reduction of glycosylated hemoglobin (HbA1c) levels, and selection and adjustment of insulin therapy.
Delphi methodology was used to achieve consensus in two survey rounds. A total of 431 Spanish endocrinologists participated in the first round of a 34-item questionnaire survey on isCGM and 427 participated in the second round. Any disagreement was resolved in round 2.
Consensus was reached for 32 statements, and four items were ultimately agreed upon SMBG after round 2. There was a high degree of consensus that isCGM helps to evaluate glycemic variability, improves HbA1c levels, and can guide therapeutic changes in type 1 diabetes patients. However, there was no consensus on the routine use of the interquartile range to evaluate glycemic variability or the selection of HbA1c as the main parameter for monitoring glycemic control.
Most Spanish experts believe that the isCGM system is appropriate for: (1) identifying glycemic variability and facilitating its management, (2) evaluating hyperglycemia as a complement of HbA1c levels, and (3) guiding therapeutic decisions on insulin selection and dosing. The isCGM system is a useful tool for patients and health care professionals to improve glycemic control in insulin-dependent diabetes.

UNASSIGNED: A proposal that an Insulin Advisory Committee develop insulin titration guidelines 100 years after its discovery.
UNASSIGNED: Glucose control metrics remain poor despite significant advances in diabetes technology.
UNASSIGNED: A century after the introduction of insulin, health care providers and patients with type 1 diabetes have worldwide access to a variety of insulin delivery devices (IDDs), glucose monitors, bolus calculators (BCs), continuous glucose monitors (CGMs), and automated insulin delivery (AID) systems. However, these advances have not enabled most patients to achieve today\'s clear A1c and time-in-range goals. Much of this failure arises from the lack of clear insulin titration guidelines for determining appropriate insulin doses. The lack of dosing clarity results in local physicians, clinics, and individual patients managing insulin titrations as they see fit, creating significant inefficiencies for reaching recommended glycemic goals. This review (1) details the widespread problems generated by nonphysiological dose settings in today\'s BCs, insulin pumps, and AID systems; (2) presents a method to develop and implement optimized total daily doses of insulin to correct the most common problem of hyperglycemia; (3) discusses using large device databases to provide clear insulin titration guidelines that optimize BC settings from an optimized total daily dose (TDD) of insulin for patients with T1D; and (4) recommends the formation of an Insulin Advisory Committee to clarify the steps to take toward universal insulin titration guidelines, optimized BC settings, and a systematic logic for their use in insulin delivery devices.

OBJECTIVE: We review the recent changes in diagnostic criteria of gestational diabetes mellitus (GDM), describe problems with maintaining and monitoring adequate blood glucose, especially in type 1 diabetes, and provide a brief overview of the currently approved glucose-lowering therapies in pregnancy.
RESULTS: After the Hyperglycemia and Adverse Pregnancy Outcomes (HAPO) study, the definition of GDM was revised under the auspices of the International Association of Diabetes and Pregnancy Study Groups. The guidelines, with minor modifications, were endorsed by WHO in 2013. Intensive debate continues, focused on the expected large increase in prevalence of GDM and shortage of experimental evidence of clinical benefits from the new diagnostic criteria. Despite a very good glycaemic control, the prevalence of macrosomia remains high. This indicates a serious deficiency in current monitoring tools and the available therapies. So far, the only glucose-lowering medications approved for use during pregnancy are insulins.
CONCLUSIONS: The HAPO study provides a very suggestive evidence for a strong, continuous association of maternal glucose levels with an increased risk of excessive foetal weight gain. The new definition of GDM results in higher healthcare expenditure, but remains cost-effective. The current therapeutic goals require careful revision to further reduce the risk of adverse outcomes. New glucose-monitoring strategies and markers, and approval of new pharmacotherapies are needed.

OBJECTIVE: To report our preliminary experience with the revised, more conservative Yale insulin infusion protocol (IIP) that targets blood glucose concentrations of 120 to 160 mg/dL.
METHODS: We prospectively tracked clinical responses to the new IIP in our medical intensive care unit (ICU) by recording data on the first 115 consecutive insulin infusions that were initiated. All blood glucose values; insulin doses; nutritional support including intravenous dextrose infusions; caloric values for enteral and parenteral nutrition; and use of vasopressors, corticosteroids, and hemodialysis or continuous venovenous hemodialysis were collected from the hospital record.
RESULTS: The IIP was used 115 times in 90 patients (mean age, 62 [±14 years]; 51% male; 35% ethnic minorities; 66.1% with history of diabetes). The mean admission Acute Physiology and Chronic Health Evaluation II score was 24.4 (±7.5). The median duration of insulin infusion was 59 hours. The mean baseline blood glucose concentration was 306.1 (±89.8) mg/dL, with the blood glucose target achieved after a median of 7 hours. Once the target was reached, the mean IIP blood glucose concentration was 155.9 (±22.9) mg/dL (median, 150 mg/dL). The median insulin infusion rate required to reach and maintain the target range was 3.5 units/h. Hypoglycemia was rare, with 0.3% of blood glucose values recorded being less than 70 mg/dL and only 0.02% being less than 40 mg/dL. In all cases, hypoglycemia was rapidly corrected using intravenous dextrose with no evident untoward outcomes.
CONCLUSIONS: The updated Yale IIP provides effective and safe targeted blood glucose control in critically ill patients, in compliance with recent national guidelines. It can be easily implemented by hospitals now using the original Yale IIP.
