Comparison of two advanced hybrid closed loop in a pediatric population with type 1 diabetes: a real-life observational study.

The Advanced Hybrid Closed Loop (AHCL) systems have provided the potential to ameliorate glucose control in children with Type 1 Diabetes. The aim of the present work was to compare metabolic control obtained with 2 AHCL systems (Medtronic 780G system and Tandem Control IQ system) in a pediatric real-life clinical context. It is an observational, real-life, monocentric study; thirty one children and adolescents (M:F = 15:16, age range 7.6-18years, mean age 13.05 ± 2.4years, Diabetes duration > 1year) with T1D, previously treated with Predictive Low Glucose Suspend (PLGS) systems and then upgraded to AHCL have been enrolled. CGM data of the last four weeks of "PLGS system" (PRE period) with the first four weeks of AHCL system (POST period) have been compared. For both AHCL systems, Medtronic 780G and Tandem Control IQ, respectively TIR at 4weeks significantly increased, from 65.7 to 70.5% (p < 0.01) and from 64.8 to 70.1% (p < 0.01). (p < 0.01). The comparison between CGM metrics of the 2 evaluated systems doesn't show difference at baseline (last four weeks of PLGS system) and after four weeks of AHCL use. To our knowledge, this study is the first real-life one comparing 2 AHCL systems in a pediatric population with T1D. It shows an improvement in glucose control when upgrading to AHCL. The comparison between the two AHCL systems did not show significant differences in the analyzed CGM metrics, meaning that the algorithms currently available are equally effective in promoting glucose control.

Diabetes-Modifying Antirheumatic Drugs: The Roles of DMARDs as Glucose-Lowering Agents.

Systemic inflammation represents a shared pathophysiological mechanism which underlies the frequent clinical associations among chronic inflammatory rheumatic diseases (CIRDs), insulin resistance, type 2 diabetes (T2D), and chronic diabetes complications, including cardiovascular disease. Therefore, targeted anti-inflammatory therapies are attractive and highly desirable interventions to concomitantly reduce rheumatic disease activity and to improve glucose control in patients with CIRDs and comorbid T2D. Therapeutic approaches targeting inflammation may also play a role in the prevention of prediabetes and diabetes in patients with CIRDs, particularly in those with traditional risk factors and/or on high-dose corticosteroid therapy. Recently, several studies have shown that different disease-modifying antirheumatic drugs (DMARDs) used for the treatment of CIRDs exert antihyperglycemic properties by virtue of their anti-inflammatory, insulin-sensitizing, and/or insulinotropic effects. In this view, DMARDs are promising drug candidates that may potentially reduce rheumatic disease activity, ameliorate glucose control, and at the same time, prevent the development of diabetes-associated cardiovascular complications and metabolic dysfunctions. In light of their substantial antidiabetic actions, some DMARDs (such as hydroxychloroquine and anakinra) could be alternatively termed “diabetes-modifying antirheumatic drugs”, since they may be repurposed for co-treatment of rheumatic diseases and comorbid T2D. However, there is a need for future randomized controlled trials to confirm the beneficial metabolic and cardiovascular effects as well as the safety profile of distinct DMARDs in the long term. This narrative review aims to discuss the current knowledge about the mechanisms behind the antihyperglycemic properties exerted by a variety of DMARDs (including synthetic and biologic DMARDs) and the potential use of these agents as antidiabetic medications in clinical settings.

Hybrid Close-Loop Systems Versus Predictive Low-Glucose Suspend and Sensor-Augmented Pump Therapy in Patients With Type 1 Diabetes: A Single-Center Cohort Study.

IntroductionPredictive low-glucose suspend (PLGS) and hybrid closed-loop (HCL) systems may improve glucose control and quality of life in type 1 diabetic individuals. This is a cross-sectional, single-center study to compare the effect on metabolic control and glucose variability of PLGS and HCL systems as compared to standard sensor-augmented pump (SAP) therapy.MethodsWe retrospectively analyzed 136 adults (men/women 69/67, mean age 47.3 ± 13.9 years) with T1D on insulin pump therapy, divided accordingly to type of insulin pump system (group 1: SAP, 24 subjects; group 2: PLGS, 49 subjects; group 3: HCL, 63 subjects). The groups were matched for age, gender, years of disease, years of CSII use, and CGM wear time.ResultsThe analysis of CGM metrics, in the three groups, showed a statistically significant different percentage of time within the target range, defined as 70–180 mg/dl, with a higher percentage in group 3 and significantly less time spent in the hypoglycemic range in groups 2 and 3. The three groups were statistically different also for the glucose management indicator and coefficient of variation percentage, which were progressively lower moving from group 1 to group 3. In the HCL group, 52.4% of subjects reached a percentage of time passed in the euglycemic range above 70%, as compared to 32.7% in those with PLGS and 20.2% in those with SAP. A positive correlation between the higher percentage of TIR and the use of auto-mode was evident in the HCL group. Finally, the three groups did not show any statistical differences regarding the quality-of-life questionnaire, but there was a significant negative correlation between CV and perceived CSII-use convenience (r = -0.207, p = 0.043).ConclusionHCL systems were more effective in improving glucose control and in reducing the risk of hypoglycemia in patients with type 1 diabetes, thereby mitigating risk for acute and chronic complications and positively affecting diabetes technologies’ acceptance.

Effectiveness of adding alarms to flash glucose monitoring in adults with type 1 diabetes under routine care

AimWhether glucose sensor alarms improve metabolic control and are accepted by individuals with diabetes is unclear. Here, we investigated whether switching from a standard flash glucose monitoring system (FGM1) to a system equipped with hypo- and hyperglycemia alarms (FGM2) improves glycemic control and psychological outcomes in adults with type 1 diabetes (T1D).MethodsSubjects with T1D and > 4% of time in hypoglycemia or > 40% of time in hyperglycemia were studied while wearing FGM1 (4 weeks) and after switching to FGM2 for 8 weeks. The primary endpoint was the change in time in range (TIR 70–180 mg/dl [3.9–10.0 mmol/L]) after 4 weeks of FGM2 use. Time below range (TBR), time above range (TAR), mean glucose, coefficient of variation (CV), sensor scans, treatment satisfaction, and hypoglycemia fear were secondary outcomes.ResultsWe included 38 subjects aged 33.7 ± 12.6 year. During 4 weeks of FGM2 use, TIR increased from 52.8 to 57.0% (p = 0.001), TBR decreased from 6.2 to 3.4% (p < 0.0001) as did time < 54 mg/dl (from 1.4 to 0.3%, p < 0.0001) and CV (from 39.6% to 36.1%, p < 0.0001). These changes were confirmed after 8 weeks of FGM2 use. Treatment satisfaction improved and fear of hypoglycemia decreased.Subjects who had > 4% of time in hypoglycemia at baseline showed the greatest improvements in glucose control and treatment satisfaction.ConclusionSwitching from FGM1 to FGM2 improved TIR and treatment satisfaction and reduced fear of hypoglycemia. Participants who benefited most from switching from FGM1 to FGM2 were those prone to hypoglycemia.

Digital Solutions to Diagnose and Manage Postbariatric Hypoglycemia.

Postbariatric hypoglycemia (PBH) is an increasingly recognized late metabolic complication of bariatric surgery, characterized by low blood glucose levels 1–3 h after a meal, particularly if the meal contains rapid-acting carbohydrates. PBH can often be effectively managed through appropriate nutritional measures, which remain the cornerstone treatment today. However, their implementation in daily life continues to challenge both patients and health care providers. Emerging digital technologies may allow for more informed and improved decision-making through better access to relevant data to manage glucose levels in PBH. Examples include applications for automated food analysis from meal images, digital receipts of purchased food items or integrated platforms allowing the connection of continuously measured glucose with food and other health-related data. The resulting multi-dimensional data can be processed with artificial intelligence systems to develop prediction algorithms and decision support systems with the aim of improving glucose control, safety, and quality of life of PBH patients. Digital innovations, however, face trade-offs between user burden vs. amount and quality of data. Further challenges to their development are regulatory non-compliance regarding data ownership of the platforms acquiring the required data, as well as user privacy concerns and compliance with regulatory requirements. Through navigating these trade-offs, digital solutions could significantly contribute to improving the management of PBH.

A Normalized Real-Life Glucose Profile After Diet-Induced Remission of Type 2 Diabetes: A Pilot Trial.

Background/objectiveType 2 diabetes related to metabolic syndrome is often partially reversible after weight loss. We conducted a pilot trial on whether complete remission to the point of a normalized real-life glucose profile, measured by continuous subcutaneous monitoring, can be achieved.MethodsWe conducted a mono-center, single-arm intervention trial between January 20, 2020, and January 12, 2021, in Munich, Germany. Ten participants had type 2 diabetes related to metabolic syndrome for a maximum of six years. They received a six-month lifestyle intervention including up to three months of a very-low-calorie formula diet, followed by stepwise food reintroduction and regular behavioral lifestyle counseling. The primary outcome was the status of glucose control at the end of the intervention. Complete remission was defined as normalization of the real-life glucose profile without glucose-lowering medication over at least five days. We measured anthropometric and biochemical parameters, body fat distribution by MRI, and insulin secretory reserve by an arginine stimulation test.ResultsSeven participants completed the trial, one reached complete remission, three achieved partial remission, and three displayed improved glucose control still in the diabetic range. A reduction of median glycosylated hemoglobin by −10 mmol/mol (−22.0 to −5.0; p = 0.016) co-occurred with weight loss of −6.4 kg (−14.2 to −3.5; p = 0.031). The insulin secretory reserve remained unchanged.ConclusionsComplete remission of type 2 diabetes related to metabolic syndrome to the point of a normalized real-life glucose profile is possible through lifestyle intervention. Full intervention success remains challenging even with intensive counseling and support.

IDF21-0043 Technology Trio: Continuous Glucose Monitoring, Telehealth, and Electronic Messaging for Insulin-Treated Patients

Background: The recent accelerated super-imposition of telemedicine on advances in continuous glucose monitoring (CGM) and electronic patient portal communication has brought about major changes in the delivery of diabetes care. Aim: We evaluated the impact of clinic-monitored proactive CGM, frequent virtual video visits, and an electronic patient-nurse-physician messaging system on glycemic parameters in patients on intensive insulin therapy. Method: In a newly-established academic endocrinology practice consisting of a diabetes specialist and a nurse clinician, CGM data was downloaded proactively every 2 weeks from computer cloud-based device accounts (LibreView for Freestyle Libre and Clarity for Dexcom G6) in 146 patients with diabetes on multiple (2-5) daily insulin injections or insulin pump therapy. The diabetes specialist interpreted the ambulatory glucose profile and individually advised patients of modifications in diet, behavior, and components of the insulin regimen by electronic portal communication linked to email, and during telehealth and in-person office visits. Results: The average time-in-range (TIR) increased from 63% to 69% (p<0.05), while the average hemoglobin A1c decreased from an inpatient value of 9.46% to 7.36% (p<0.05) over a mean period of 12 months. The CGM adherence rate was close to 100%. Discussion: Improved glucose control is seen in insulin-treated outpatients when CGM data analysis by remote upload capabilities is employed in a routine clinician-initiated and proactive fashion and coupled with convenient interactive technology like telehealth and electronic messaging. Impact on hypoglycemia rates and patient satisfaction levels remain to be determined.

A role for the diabetes nurse educator to telemedically support children with type 1 diabetes on continuous glucose monitoring? The COVID-19 lockdown experience

The role of diabetes nurse educators during the COVID-19 lockdown to telematically provide routine reviews of glycaemic control in children with type 1 diabetes (T1D) using continuous glucose monitoring systems is evaluated. Implementing these routines in the day-to-day clinical practice could reduce in-person clinic visits and improve glucose control.

Long-term cost-effectiveness of Dexcom G6 real-time continuous glucose monitoring system in people with type 1 diabetes in Australia.

IntroductionReal‐time continuous glucose monitoring (rt‐CGM) allows patients with diabetes to adjust insulin dosing, potentially improving glucose control. This study aimed to compare the long‐term cost‐effectiveness of the Dexcom G6 rt‐CGM device versus self‐monitoring of blood glucose (SMBG) and flash glucose monitoring (FGM) in Australia in people with type 1 diabetes (T1D).MethodsLong‐term costs and clinical outcomes were estimated using the CORE Diabetes Model. Clinical input data for the analysis of rt‐CGM versus SMBG and FGM were sourced from the DIAMOND study and a network meta‐analysis, respectively. Rt‐CGM and FGM were associated with quality of life (QoL) benefits due to reduced fear of hypoglycaemia (FoH) and fingerstick testing. Analyses were performed over a lifetime time horizon from an Australian healthcare payer perspective, including direct costs from published data. Future costs and clinical outcomes were discounted at 5% per annum.ResultsRt‐CGM was associated with an increased quality‐adjusted life expectancy of 1.199 quality‐adjusted life years (QALYs), increased mean total lifetime costs of AUD 21,596 and an incremental cost‐effectiveness ratio (ICER) of AUD 18,020 per QALY gained compared with SMBG.Compared with FGM, rt‐CGM was associated with an increased quality‐adjusted life expectancy of 0.569 QALYs, increased mean total lifetime costs of AUD 11,064 and an ICER of AUD 19,455 per QALY gained. Key drivers of outcomes included HbA1c benefits and QoL benefits associated with reduced FoH and fingerstick testing.ConclusionsDue to improved clinical outcomes and QoL gains rt‐CGM is highly cost‐effective compared with SMBG and FGM in people with T1D in Australia.

Effective Overall Glycaemic Control with Fast-Acting Insulin Aspart Across Patients with Different Baseline Characteristics: A Post Hoc Analysis of the Onset 9 Trial

AimsTo investigate the efficacy and safety of fast-acting insulin aspart (faster aspart) compared with insulin aspart (IAsp) in participants with type 2 diabetes (T2D) across different subgroups.MethodsWe report on a post hoc analysis of onset 9, a 16-week trial of participants with T2D randomised to faster aspart (n = 546) or IAsp (n = 545). Participants were grouped by baseline HbA1c (< 7.0%, ≥ 7.0%), meal test bolus insulin dose (≤ 10 units [U], > 10 U to ≤ 20 U, > 20 U), body mass index (< 30 kg/m2, ≥ 30 to < 35 kg/m2, ≥ 35 kg/m2), and age (< 65 years, ≥ 65 years). Outcomes assessed were change from baseline in HbA1c and in 1-h postprandial glucose (PPG) increment, and severe or blood glucose (BG)-confirmed hypoglycaemia.ResultsFaster aspart provided reductions in HbA1c comparable to IAsp across all subgroups, with improved 1-h PPG control compared with IAsp in several subgroups. Faster aspart had comparable or improved rates of severe or BG-confirmed hypoglycaemia versus IAsp, particularly in participants with good glycaemic control (HbA1c < 7.0%), the elderly (≥ 65 years old), and those with insulin resistance (> 20 U meal test bolus insulin dose).ConclusionsFaster aspart provides effective overall glycaemic control, with improved early PPG control compared with IAsp across a range of patient characteristics.Clinical Trial RegistrationNCT03268005.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13300-022-01213-3.

PalatinoseTM (Isomaltulose) and Prebiotic Inulin-Type Fructans Have Beneficial Effects on Glycemic Response and Gut Microbiota Composition in Healthy Volunteers-A Real-Life, Retrospective Study of a Cohort That Participated in a Digital Nutrition Program.

It is well-appreciated that the diet is a crucial tool to counteract cardiometabolic disturbances due to its impact on blood glucose concentration and gut microbiome. This retrospective analysis aimed to examine whether the inclusion of isomaltulose and prebiotic inulin-type fructans (ITF) into the habitual diet has an impact on glycemic control and gut microbiota. Furthermore, we examined interindividual differences in glycemic response to sugar replacement with isomaltulose. We retrospectively analyzed data of 117 individuals who participated in a digital nutrition program including a 14-day continuous glucose measurement. Participants underwent six test days with sweetened drinks (isomaltulose vs. sucrose) consumed with their usual breakfasts and lunches. Dinner was supplemented with ITF for 11 days. Postprandial glycemia and 24 h-glycemic variability were determined following test meals and days, respectively. Fecal microbiota was analyzed by 16S rRNA sequencing before and after test phase. Meals with isomaltulose-sweetened drinks compared to meals with sucrose-sweetened drinks induced lower postprandial glycemia. Moreover, glucose oscillations over 24 h were lower on isomaltulose when compared to sucrose test days and improved further during ITF supplementation. Furthermore, ITF modulated gut microbiota composition beneficially. Responder analysis revealed that 72% of participants benefited from the sugar replacement with isomaltulose and that their gut microbiota differed from the low responders. Taken together, the incorporation of isomaltulose and ITF into the habitual diet was shown to be an effective strategy to improve glucose control and beneficially modulate gut microbiota, and thereby aid to maintain metabolic health. Data indicate interindividual differences in glycemic response to ingredients and suggest that gut microbiota might be somehow related to it.

The Effects of C. lacerata on Insulin Resistance in Type 2 Diabetes Patients.

Background Several experimental studies have suggested beneficial effects of Ceriporia lacerata on glucose metabolism. However, there has been no human study assessing the effects of C. lacerata on glucose metabolism. Therefore, we investigated whether C. lacerata improves glucose control and insulin resistance in type 2 diabetes patients. Methods Ninety patients diagnosed with type 2 diabetes (T2DM) for more than 6 months were enrolled. Subjects were randomly divided into placebo (n = 45) or C. lacerata (n = 45) groups and then assigned to take placebo or C. lacerata capsules (500 mg/capsule) for a 12-week intervention period. Biochemical markers, including fasting glucose, 2-hour postprandial plasma glucose, and lipid profile levels, as well as insulin, c-peptide, and Hba1c, were measured. Furthermore, insulin sensitivity indices, such as HOMA-IR, HOMA-beta, and QUICKI, were assessed before and after the 12-week administration. Results Eighty-four patients completed the study. There were no significant differences in fasting, postprandial glucose, HbA1c, or lipid parameters. HOMA-IR and QUICKI indices were improved at week 12 in the C. lacerata group, especially in subjects with HOMA-IR of 1.8 or more (p < 0.05). Fasting, postprandial c-peptide, and insulin levels decreased at week 12 in the C. lacerata group (p < 0.05). These significant differences were not observed in the placebo group. Conclusion Twelve-week administration of C. lacerata in T2DM patients resulted in significant improvement in insulin resistance, especially in those with lower insulin sensitivity. A larger population study with a longer follow-up period and an effort to elucidate the mechanism is warranted to further assess the effects of C. lacerata on T2DM patients.

Switching from predictive low glucose suspend to advanced hybrid closed loop control: Effects on glucose control and patient reported outcomes

AimsAutomated insulin delivery improves glucose control. Aim of this study was to compare in real life the effects on glucose control and patient reported outcomes of an advanced hybrid closed loop system (Control-IQ), versus a simpler system with predictive low glucose suspend function (Basal-IQ). MethodsThirty-one type 1 diabetic subjects were studied during Basal-IQ and after switching to Control-IQ. Variables analyzed were time spent in range (70–180 mg/dL), in tight range (70–140 mg/dL), above range (>180 mg/dL), below range (<70 mg/dL), mean glucose, coefficient of variation and glycated hemoglobin. Questionnaires were administered regarding therapy satisfaction (Diabetes Treatment Satisfaction Questionnaire in status/change form), fear of hypoglycemia (Hypoglycemia Fear Survey), quality of sleep (Pittsburgh Sleep Quality Index). ResultsAfter 12 weeks of Control-IQ, time in range increased from 62.7 to 74.0%, p < 0.0001, time in tight range increased from 37.1 to 44.6 %, p < 0.001, time above range decreased from 35.6 to 24.4% p < 0.0001. Improvements were observed in mean glucose and glucose variability. Glycated hemoglobin decreased from 7.0% (53 mmol/mol) to 6.6% (49 mmol/mol), p < 0.0001. Subjects using Control-IQ manifested greater satisfaction and less fear of hypoglycemia. ConclusionCompared to Basal-IQ, Control-IQ improves glucose control and therapy satisfaction.

Effect of the New Nordic Diet compared with usual care on glucose control in gestational diabetes mellitus: Study protocol for the randomized controlled trial intervention with new Nordic DIet in women with GestatiOnal diabetes mellitus (iNDIGO)

BackgroundGestational diabetes mellitus (GDM) is a pregnancy complication associated with short- and long-term health consequences for mother and child. First line treatment is diet and exercise but there is a recognized knowledge gap as to what diet treatment is optimal. A healthy Nordic diet has been associated with improved health but no studies in women with GDM exist. The New Nordic Diet (NND) is an initiative with the purpose to develop a healthy Nordic diet including foods with the potential to grow in Nordic countries; including fruit, berries, vegetables, whole-grain cereal products, nuts, fish, and rapeseed oil. The purpose of the intervention with new Nordic DIet in women with GestatiOnal diabetes mellitus (iNDIGO) is to test if the NND compared with usual care improves glucose control in women with GDM. MethodsThe iNDIGO study is a randomized parallel controlled trial where 50 women with GDM will be randomized to either an NND or usual care for 14 days (30–32 weeks of gestation). Participants in the NND group will receive menus and food bags containing foods to be consumed. Primary outcome is glycemic control (time in target) measured using continuous glucose monitoring. Compliance to the dietary intervention will be tested using dietary biomarkers and adherence questionnaires. ConclusionDiet treatment represents first line treatment in GDM but it remains unclear what type of diets are effective. iNDIGO is an efficacy study and will provide evidence as to whether a healthy Nordic diet can improve glucose control in women with GDM.Trial registration: ClinicalTrials.gov registration Number: NCT04169243.

The impact of type 1 diabetes mellitus in childhood on academic performance: A matched population-based cohort study.

Background and ObjectiveThe impact of type 1 diabetes mellitus (T1D) on academic performance is inconclusive. This study aims to compare scholastic performance and high‐school completion in young people hospitalized with T1D compared to matched peers not hospitalized with diabetes.Research DesignRetrospective case‐comparison cohort study.MethodA population‐level matched case‐comparison study of people aged ≤18 hospitalized with T1D during 2005–2018 in New South Wales, Australia using linked health‐related and education records. The comparison cohort was matched on age, gender, and residential postcode. Generalized linear mixed modeling examined risk of school performance below the national minimum standard (NMS) and generalized linear regression examined risk of not completing high school for young people hospitalized with T1D compared to peers. Adjusted relative risks (ARR) were calculated.ResultsYoung females and males hospitalized with T1D did not have a higher risk of not achieving the NMS compared to peers for numeracy (ARR: 1.19; 95%CI 0.77–1.84 and ARR: 0.74; 95%CI 0.46–1.19) or reading (ARR: 0.98; 95%CI 0.63–1.50 and ARR: 0.85; 95%CI 0.58–1.24), respectively. Young T1D hospitalized females had a higher risk of not completing year 11 (ARR: 1.73; 95%CI 1.19–2.53) or 12 (ARR: 1.65; 95%CI 1.17–2.33) compared to peers, while hospitalized T1D males did not.ConclusionsThere was no difference in academic performance in youth hospitalized with T1D compared to peers. Improved glucose control and T1D management may explain the absence of school performance decrements in students with T1D. However, females hospitalized with T1D had a higher risk of not completing high school. Potential associations of this increased risk, with attention to T1D and psycho‐social management, should be investigated.

Sensor-Based Technology: Bringing Value to People with Diabetes and the Healthcare System in an Evolving World.

PurposeEvidence demonstrates that glucose-sensing technologies have enabled effective glycemic control for adults and children with type 1 diabetes (T1DM) or adults with type 2 diabetes (T2DM) on insulin therapy or non-insulin therapy. Here, we report on the wider value of glucose-sensing technology from the perspectives of person living with diabetes (PWD), healthcare providers (HCPs), and healthcare policy stakeholders.MethodologyLiterature searches were conducted to identify published records and analysis, including across various healthcare organizations and agencies, of the impact of the FreeStyle Libre® flash glucose monitoring system in diabetes. These findings were combined with the outcomes of three healthcare attitudes surveys among PWD and diabetes healthcare professionals in Canada, including two commissioned for this purpose.ResultsClinical trials data and real-world evidence have proven the benefits of the FreeStyle Libre system on limiting hypoglycemia, lowering HbA1c, optimizing metrics of glucose control and reducing hospital admissions. These benefits are accompanied by improvements in patients’ quality of life, work productivity, and savings to the health system. The FreeStyle Libre system has created an opportunity to change the organization and delivery of care, including during COVID-19 restrictions on access to standard care, thus generating system-wide benefits in addition to those accrued by patients and HCPs.ConclusionEvidence-based improvements in glucose control for PWD using flash glucose monitoring are accompanied by increased treatment satisfaction and quality of life. Telemedicine with such remote monitoring systems increases the opportunities for simultaneous review of glucose data with HCPs and shared decision-making, thus encouraging adherence with treatment.

Diabetes workshops for providers improve glucose control in coronary artery bypass grafting patients.

Postoperative hyperglycemia occurs in up to 80% of cardiac surgery patients and is associated with poor outcomes. We sought to determine if case-based diabetes workshops for providers would improve postoperative glycemic control and outcomes in patients undergoing coronary artery bypass grafting (CABG). Healthcare providers taking care of patients in the cardiothoracic step-down unit underwent 30-min weekly case-based diabetes workshops over 6 months. Workshops focused on initiation of insulin treatment, titration of insulin dosing, and transitioning from insulin drips to subcutaneous insulin. Isolated-CABG patients were recorded during 29-month periods before (Jan 2013-June 2015) and after training (Jan 2016-June 2018). Glycemic control and outcomes were compared between groups balanced for preoperative risk factors using inverse probability treatment weights. A total of 938 and 1032 patients were included in pre- and posttraining groups, respectively. Compared to the pretraining period, the posttraining period had a lower median of mean patient day glucose levels (151 vs. 144 mg/dl, p < .001) and percentage of patient days with a glucose level >250 mg/dl (20% vs. 14%, p < .001). The percentage of patient days with mean glucose values in the target range (80-180 mg/dl) increased from 71% to 77% (p < .001). The incidence of hypoglycemic events did not significantly change after training (p = .15). The incidence of sepsis was significantly lower in the posttraining period (1.7% vs. 0.2%, p < .001). Weekly diabetes workshops for healthcare providers were associated with improved glycemic control and reduced postoperative sepsis among isolated CABG patients.

Tolerability, Safety, Pharmacokinetics, and Pharmacodynamics of SY-004, a Glucokinase Activator, in Healthy Chinese Adults: A Randomized, Phase Ia, Single-Ascending Dose Study

PurposeSY-004, a dual-acting full glucokinase activator, is under development to provide a dose-dependent improvement of glucose control. This study aimed to assess the tolerability, safety, and pharmacokinetic and pharmacodynamic properties of SY-004 in healthy Chinese adults. MethodsTwo study participants were administered 2 mg of SY-004 in the 2-mg cohort, whereas 6 study participants were randomized with 4 study participants receiving SY-004 and 2 receiving placebo in the 20-mg cohort. In each of other 3 dose cohorts (40, 80, and 120 mg), 12 participants were randomized in a 10:2 ratio to receive single oral SY-004 capsules or placebos. Drug concentrations, glucose and insulin levels, and safety data were assessed and analyzed. Noncompartmental analysis was used to determine SY-004 pharmacokinetic parameters. FindingsSY-004 was generally well tolerated. Nine of the 44 study participants reported 17 treatment-related adverse events, and most treatment-related adverse events were mild. SY-004 had approximately dose-proportional increases in systemic exposure. The mean t½ ranged from 37.6 to 49.9 hours, and CL/F values ranged from 67.1 to 110 L/h across all doses. The cumulative amounts of the unchanged drug excreted in urine were very low, accounting for no more than 1.53% of the given doses. No significant difference in sex was observed in pharmacokinetic parameters. The pharmacodynamic response appeared to slightly correlate with dose. ImplicationsSY-004, a new potential glucokinase activator, had favorable safety profiles and good PK characteristics. The glucose-lowering effects were slightly dose related. The SY-004 data in healthy Chinese adults supports further development. ClinicalTrials.gov identifier: NCT03171623.

Comparison of the Outcomes of Single Anastomosis Duodeno-Ileostomy with Sleeve Gastrectomy (SADI-S), Single Anastomosis Sleeve Ileal (SASI) Bypass with Sleeve Gastrectomy, and Sleeve Gastrectomy Using a Rodent Model with Diabetes.

Single anastomosis duodeno-ileostomy with sleeve gastrectomy (SADI-S) is a powerful form of bariatric surgery; however, it has a high risk of malnutrition. Single anastomosis sleeve ileal (SASI) bypass with sleeve gastrectomy may be used as an alternative procedure to avoid malnutrition associated with SADI-S; however, no comparison between the two procedures has been performed. Sprague-Dawley rats with diabetes (n = 32) were divided into four groups: SADI-S (n = 8), SASI (n = 8), SG (n = 8), and SHAM (n = 8). Body weight, food intake, and fasting blood glucose were measured, and the oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were performed before and after surgery. Blood samples were collected before and after the surgery to assess the levels of glucagon-like peptide-1 (GLP-1), hemoglobin, albumin, vitamin B12, calcium, and iron. The SADI-S and SASI groups showed significantly greater weight loss and better glucose control than the SG group postoperatively. The SADI-S and SASI groups showed similar improvements in glucose control throughout the study. The SADI-S and SASI groups had significantly higher GLP-1 levels than the SG group at 6months. The SADI-S and SASI groups presented with various degrees of deficiencies, with the SADI-S group showing a higher risk for hypoalbuminemia and iron deficiency than the SASI group. The SASI procedure may be a better alternative as it has excellent bariatric and metabolic results with lower risk for hypoalbuminemia and can be easily converted into either SADI-S or SG procedures. Nevertheless, further clinical results are needed.

Correlations between Diabetes Mellitus Self-Care Activities and Glycaemic Control in the Adult Population: A Cross-Sectional Study.

Although it is well known that lifestyle changes can affect plasma glucose levels, there is little formal evidence for the sustained effectiveness of exercise and diet in diabetes mellitus (DM) management. Self-care in DM refers to the real-life application of the knowledge that the patient gained during the education programmes. The goals are to bring about changes in the patient’s behaviour, thus improving glycaemic control. We evaluated the influence of DM self-care activities (SCA) on glycaemic control in a total of 159 patients with DM. Plasma glycated haemoglobin (HbA1c) levels were used to monitor glycaemic control, while SCA were assessed using the standardised Diabetes Self-Management Questionnaire (DSMQ). In our study, 53% of the patients had a HbA1c ≥ 7%. In univariate linear regression models, a statistically significant inverse association was observed between the HbA1c (the dependent variable) and both the DSMQ Dietary Control Score (R2 = 0.037, p = 0.0145) and the DSMQ Sum Score (R2 = 0.06, p = 0.0014). The mean absolute change in the HbA1c% associated with one standard deviation (SD) change in the DSMQ Sum Score, independent of the other significant variables retained in the compacted multivariate regression model, was −0.419% (confidence interval: 95%: from −0.18 to −0.65). Although the impact of the DSMQ Score was modest when compared to the other independent variables in the multivariate model, the findings emphasise the importance of maintaining optimal lifestyle changes to avoid hyperglycaemia and its complications. In conclusion, enhanced self-management of DM is associated with improved glucose control. In patients with chronic diseases such as DM, the role of streamlining SCA encompassing physical activity and proper dietary choices is imperative because of a significantly reduced access to healthcare globally as a result of the COVID-19 pandemic.
