Automated insulin dosing guidance to optimise insulin management in patients with type 2 diabetes: a multicentre, randomised controlled trial. Insulin therapy is most effective if dosage titrations are done regularly and frequently, which is seldom practical for most clinicians, resulting in an insulin titration gap. The d-Nav Insulin Guidance System (Hygieia, Livonia, MI, USA) is a handheld device that is used to measure glucose, determine glucose patterns, and automatically determine (...) the appropriate next insulin dose. We aimed to determine whether the combination of the d-Nav device and health-care professional support is superior to health-care professional support alone.In this multicentre, randomised, controlled study, we recruited patients from three diabetes centres in the USA (in Detroit MI; Minneapolis, MN; and Des Moines IA). Patients were eligible if they were aged 21-70 years, diagnosed with type 2 diabetes with a glycated haemoglobin (HbA1c) concentration of 7·5% or higher (≥58
A randomized, multicentre trial evaluating the efficacy and safety of fast-acting insulin aspart in continuous subcutaneous insulin infusion in adults with type 1 diabetes (onset 5) To evaluate the efficacy and safety of fast-acting insulin aspart (faster aspart) vs insulin aspart (IAsp) used in continuous subcutaneous insulin infusion (CSII) in participants with type 1 diabetes (T1D).This was a double-blind, treat-to-target, randomized, 16-week trial investigating CSII treatment with faster
Comparative effectiveness and harms of long-acting insulins for type 1 and type 2 diabetes: A systematic review and meta-analysis To review evidence comparing benefits and harms of long-acting insulins in patients with type 1 and 2 diabetes.MEDLINE and two Cochrane databases were searched during February 2018. Two authors selected studies meeting inclusion criteria and assessed their quality. Comparative studies of adult or paediatric patients with diabetes treated with insulin degludec (...) , detemir or glargine were included. Meta-analysis was used to combine results of similar studies, and the I2 statistic calculated to assess statistical heterogeneity.Of 2534 citations reviewed, 70 studies met the inclusion criteria. No statistically significant differences in HbA1c were seen between any two insulins or formulations. Hypoglycaemia was less probable with degludec than with glargine, including nocturnal hypoglycaemia in type 1 (rate ratio 0.68, 95% CI 0.56-0.81) and type 2 diabetes (rate
The effects of incretin-based therapies on beta-cell function and insulin resistance in type 2 diabetes: A systematic review and network meta-analysis combining 360 trials To evaluate the comparative effects of incretin-based therapies, including glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and dipeptidyl peptidase-4 inhibitors (DPP-4Is), on β-cell function and insulin resistance in patients with type 2 diabetes mellitus (T2DM).Medline, Embase, the Cochrane Library (...) and www.clinicaltrials.gov were searched for randomized controlled trials (RCTs) with a duration of at least 4 weeks. Network meta-analysis was performed, followed by subgroup analysis and meta-regression. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was used to assess the quality of evidence. Outcomes of interest include homeostasis model assessment for β cell function (HOMA-β) and insulin resistance (HOMA-IR), fasting C-peptide and fasting plasma glucose (FPG). Weighted mean
Association of Long-term Child Growth and Developmental Outcomes With Metformin vs Insulin Treatment for Gestational Diabetes Metformin is an emerging option for treating gestational diabetes (GDM). However, because metformin crosses the placenta, patients and clinicians are concerned with its long-term effect on child health.To estimate the association of treating GDM with metformin vs insulin with child growth and development.Population-based cohort study of New Zealand women treated (...) with metformin or insulin for GDM from 2005 to 2012 and their children. This study linked national health care data to create a cohort of mothers and their children, including data from maternity care, pharmaceutical dispensing, hospitalizations, demographic records, and the B4 School Check (B4SC) preschool health assessment. Women treated pharmacologically with metformin or insulin during pregnancy were included. We excluded pregnancies with evidence of diabetes and deliveries prior to 2013. Liveborn
Effects of Intermittent Versus Continuous Energy Intakes on Insulin Sensitivity and Metabolic Risk in Women with Overweight This study aimed to compare intermittent fasting (IF) versus continuous energy intakes at 100% or 70% of calculated energy requirements on insulin sensitivity, cardiometabolic risk, body weight, and composition.Women with overweight (n = 88; 50 ± 1 years, BMI 32.3 ± 0.5 kg/m2 ) were randomized to one of four diets (IF70, IF100, dietary restriction [DR70], or control (...) ) in a 2:2:2:1 ratio for 8 weeks. IF groups fasted for 24 hours after breakfast on three nonconsecutive days per week. All foods were provided and diets matched for macronutrient composition (35% fat, 15% protein, 50% carbohydrate). Insulin sensitivity by hyperinsulinemic-euglycemic clamp, weight, body composition, and plasma markers were assessed following a "fed" day (12-hour fast) and a 24-hour fast (IF only).IF70 displayed greater reductions in weight, fat mass, total- and low-density lipoprotein
Implementation of a Health Plan Program for Switching From Analogue to Human Insulin and Glycemic Control Among Medicare Beneficiaries With Type 2 Diabetes. Prices for newer analogue insulin products have increased. Lower-cost human insulin may be effective for many patients with type 2 diabetes.To evaluate the association between implementation of a health plan-based intervention of switching patients from analogue to human insulin and glycemic control.A retrospective cohort study using (...) population-level interrupted times series analysis of members participating in a Medicare Advantage and prescription drug plan operating in 4 US states. Participants were prescribed insulin between January 1, 2014, and December 31, 2016 (median follow-up, 729 days). The intervention began in February 2015 and was expanded to the entire health plan system by June 2015.Implementation of a health plan program to switch patients from analogue to human insulin.The primary outcome was the change in mean

Education remains important. While both groups saw improvements in blood glucose levels and fewer hypoglycaemic episodes (very low blood sugar) over two years, only one in four participants met NICE blood glucose targets. Insulin pump users showed some modest improvements in satisfaction, dietary freedom and daily hassle. All participants in this NIHR trial attended a training course on managing their insulin levels before randomisation. This is important because previously observed benefits from pump
Continuous insulin pumps may help manage poorly controlled type 2 diabetes Continuous insulin pumps may help manage poorly controlled type 2 diabetes Discover Portal Discover Portal Continuous insulin pumps may help manage poorly controlled type 2 diabetes Published on 18 July 2017 doi: Continuous subcutaneous insulin infusions, or pumps, reduced the amount of daily insulin required by 24 units for people with advanced type 2 diabetes compared to multiple daily insulin injections. Average (...) weight did not differ between treatments. This review compared the two treatments in 590 people from five trials and found that the pumps were linked to slightly better control for people on higher doses of insulin and those with poorer glucose control. However, looking at all the people with diabetes in these studies, there was no difference in overall control between the different forms of treatment. One main challenge in controlling type 2 diabetes is the low adherence to treatment. Other studies
Insulin pumps offer little value over multiple injections for children at the onset of diabetes Insulin pumps or multiple injections for children at onset of diabetes Discover Portal Discover Portal Insulin pumps offer little value over multiple injections for children at the onset of diabetes Published on 20 November 2018 doi: Young people newly diagnosed with type 1 diabetes achieve similar blood glucose control by 12 months if they are treated with multiple daily insulin injections (...) or continuously via an insulin pump. Adverse events are rare and occur at similar rates. Pumps are more expensive with no clear benefit to quality of life. Both regimens are used in the management of type 1 diabetes, and the number of children using insulin pumps is rising. This NIHR-funded trial suggests that at an additional cost of £1,863 per patient annually with equivalent outcomes, the high costs of insulin pumps seem unjustified at this stage of the condition. However, continuous insulin may be more
Hypoglycaemia as a function of HbA1c in type 2 diabetes: Insulin glargine 300 U/mL in a patient-level pooled analysis of EDITION 1, 2 and 3 Basal insulin therapy often involves a compromise between achievement of glycaemic targets and avoidance of hypoglycaemia, dependent on how intensively insulin is titrated. In the Phase 3a EDITION 1, 2 and 3 studies, insulin glargine 300 U/mL (Gla-300) provided glycaemic control equivalent to that of insulin glargine 100 U/mL (Gla-100), with less
Glycaemic Efficacy and Safety of Linagliptin compared to Basal-Bolus Insulin Regimen in Patients with Type 2 Diabetes Undergoing Non-Cardiac Surgery: A Multicenter Randomized Clinical Trial The use of incretin-based therapy instead of or complementary to insulin therapy is an active area of research in hospitalized patients with type 2 diabetes (T2D). We determined glycaemic efficacy and safety of linagliptin compared to basal-bolus insulin regimen in hospitalized surgical patients (...) with T2D.This prospective open-label multicenter study randomized T2D patients undergoing non-cardiac surgery with admission blood glucose(BG) 7.8-22.2 mmol/L treated with diet, oral agents or total insulin dose(TDD) ≤0.5 units/kg/day to linagliptin(n=128) daily or basal-bolus(n=122) with glargine once daily and rapid-acting insulin before meals. Both groups received supplemental insulin for BG>7.8 mmol/L. The primary endpoint was difference in mean daily BG between groups.Mean daily BG was inferior
Insulin glargine/lixisenatide fixed-ratio combination improves glycaemic variability and control without increasing hypoglycaemia Maintaining optimal glycaemic control reduces the risk of micro- and macrovascular complications in patients with type 2 diabetes. Typically, glycaemic control is based on glycated haemoglobin (HbA1c) as a measure of mean glucose concentration; however, this marker does not accurately reflect glycaemic variability (GV), which is characterized by the amplitude (...) , frequency and duration of hypo- and hyperglycaemic fluctuations. In the present study, we analysed data from the LixiLan-O trial, which compared iGlarLixi, a titratable fixed-ratio combination of the glucagon-like peptide-1 receptor agonist lixisenatide (Lixi) and long-acting basal insulin glargine 100 units/mL (iGlar), with its individual components, and the LixiLan-L trial, which compared iGlarLixi with iGlar. The GV features that were measured were mean and SD of self-measured plasma glucose (SMPG
Metformin Improves Insulin Sensitivity and Vascular Health in Youth With Type 1 Diabetes Mellitus Cardiovascular disease is the leading cause of mortality in type 1 diabetes mellitus (T1DM) and relates strongly to insulin resistance (IR). Lean and obese adolescents with T1DM have marked IR. Metformin improves surrogate markers of IR in T1DM, but its effect on directly measured IR and vascular health in youth with T1DM is unclear. We hypothesized that adolescents with T1DM have impaired vascular (...) , fasting laboratories after overnight glycemic control, and insulin sensitivity by hyperinsulinemic-euglycemic clamp (glucose infusion rate/insulin). Adolescents with T1DM were randomized 1:1 to 3 months of 2000 mg metformin or placebo daily, after which baseline measures were repeated.Forty-eight adolescents with T1DM who were 12 to 21 years of age (40% body mass index [BMI] ≥90th percentile; 56% female) and 24 nondiabetic control participants of similar age, BMI, and sex distribution were enrolled
DREAM5: An open-label, randomized, cross-over study to evaluate the safety and efficacy of day and night closed-loop control by comparing the MD-Logic automated insulin delivery system to sensor augmented pump therapy in patients with type 1 diabetes at h Previous DREAM studies demonstrated the safety and efficacy of the CE marked MD-Logic closed-loop system (DreaMed GlucoSitter) in different settings for overnight glycaemic control. The present study aimed to evaluate the system for day (...) and night use for 60 hours during the weekend at home compared to sensor-augmented pump (SAP) therapy in participants with type 1 diabetes.This was a prospective, multicentre, crossover, controlled study (clinicaltrials.gov NCT01238406). All participants were connected in randomized order for one weekend to SAP therapy or the MD-Logic System. In the intervention arm only, the amount of carbohydrate was entered into the bolus calculator; the rest of insulin delivery was automated and wireless via
Optimal Insulin Correction Factor in Post-High-Intensity Exercise Hyperglycemia in Adults With Type 1 Diabetes: The FIT Study Postexercise hyperglycemia, following high-intensity interval training (HIIT) in patients with type 1 diabetes (T1D), is largely underrecognized by the clinical community and generally undertreated. The aim of this study was to compare four multipliers of an individual's insulin correction factor (ICF) to treat post-HIIT hyperglycemia.The FIT study had a randomized (...) , crossover design in physically active subjects with T1D (mean ± SD age 34.9 ± 10.1 years, BMI 25.5 ± 2.5 kg/m2, and HbA1c 7.2 ± 0.9%) using multiple daily injections. Following an 8-week optimization period, with 300 units/mL insulin glargine used as the basal insulin, subjects performed four weekly sessions of 25 min of HIIT. If hyperglycemia (>8.0 mmol/L) resulted, subjects received a bolus insulin correction 15 min post-HIIT, based on their own ICF, adjusted by one of four multipliers: 0, 50, 100
Double-blind, randomized clinical trial comparing the efficacy and safety of continuing or discontinuing the dipeptidyl peptidase-4 inhibitor sitagliptin when initiating insulin glargine therapy in patients with type 2 diabetes: The CompoSIT-I Study To compare the effects of continuing versus discontinuing sitagliptin when initiating and intensively titrating insulin glargine.Eligible patients had inadequately controlled type 2 diabetes on metformin (≥1500 mg/d) in combination with a dipeptidyl (...) peptidase-4 (DPP-4) inhibitor and/or a sulphonylurea. Those on metformin + sitagliptin were directly randomized; all others were switched to metformin + sitagliptin (discontinuing other DPP-4 inhibitors and sulphonylureas) and stabilized during a run-in period. At randomization, patients were allocated to continuing sitagliptin or discontinuing sitagliptin, with both groups initiating insulin glargine and titrating to a target fasting glucose of 4.0 to 5.6 mmol/L.A total of 743 participants (mean
A pilot randomized controlled trial of 6-week combined exercise program on fasting insulin and fitness levels in individuals with spinal cord injury. The aim of this randomized controlled trial study was to investigate the effect of combined exercise program on the fasting insulin and fitness levels of people with spinal cord injury (SCI).A total of 19 individuals with SCI participated in a combined exercise program consisting of aerobic and resistance exercises for 60 min per day, 3 days per (...) week for 6 weeks. Peak oxygen consumption, body mass index, percent body fat, waist circumference, shoulder abduction and adduction, shoulder flexion and extension, elbow flexion and extension, fasting insulin levels, and homeostasis model assessment of insulin resistance (HOMA-IR) levels were measured at baseline and after the intervention.The 6-week exercise program significantly decreased the average fasting insulin (baseline: 7.5 ± 4.7 µU/ml vs. post-intervention: 4.5 ± 2.2 µU/ml, p < 0.05
Short-acting insulin analogues versus regular human insulin for adult, non-pregnant persons with type 2 diabetes mellitus. The use of short-acting insulin analogues (insulin lispro, insulin aspart, insulin glulisine) for adult, non-pregnant people with type 2 diabetes is still controversial, as reflected in many scientific debates.To assess the effects of short-acting insulin analogues compared to regular human insulin in adult, non-pregnant people with type 2 diabetes mellitus.For this update (...) we searched CENTRAL, MEDLINE, Embase, the WHO ICTRP Search Portal, and ClinicalTrials.gov to 31 October 2018. We placed no restrictions on the language of publication.We included all randomised controlled trials with an intervention duration of at least 24 weeks that compared short-acting insulin analogues to regular human insulin in the treatment of people with type 2 diabetes, who were not pregnant.Two review authors independently extracted data and assessed the risk of bias. We assessed
Sliding scale insulin for non-critically ill hospitalised adults with diabetes mellitus. Diabetes mellitus is a metabolic disorder resulting from a defect in insulin secretion, function, or both. Hyperglycaemia in non-critically ill hospitalised people is associated with poor clinical outcomes (infections, prolonged hospital stay, poor wound healing, higher morbidity and mortality). In the hospital setting people diagnosed with diabetes receive insulin therapy as part of their treatment (...) in order to achieve metabolic control. However, insulin therapy can be provided by different strategies (sliding scale insulin (SSI), basal-bolus insulin, and other modalities). Sliding scale insulin is currently the most commonly used method, however there is uncertainty about which strategy provides the best patient outcomes.To assess the effects of SSI for non-critically ill hospitalised adults with diabetes mellitus.We identified eligible trials by searching MEDLINE, Embase, LILACS
