Objective: Adults with type 1 diabetes (T1D) are increasingly overweight or obese, in part due to intensive insulin therapy. Newer non-insulin medications targeting both hyperglycemia and weight loss are approved for people with type 2 diabetes. These drugs also reduce cardiovascular disease, the major cause of mortality in people with diabetes. We assessed the real-world use of semaglutide and tirzepatide, in adults with T1D followed in a specialty diabetes clinic. Materials and Methods: This retrospective chart review included 100 adults who were prescribed semaglutide or tirzepatide (50 each) and 50 controls frequency matched for age, sex, diabetes duration, body mass index, and glycosylated hemoglobin (HbA1c) and who did not receive any weight loss medications during the study period. Data were collected prior to initiation of weight loss medications (baseline) and then for up to 1 year for each patient. Results: Matching characteristics did not differ between cases and controls. There were declines in weight in both semaglutide (-19.2 ± standard error (SE) 2.9 lbs. [9.1% body weight lost]) and tirzepatide (-49.4 ± SE 3.0 lbs. [21.4% body weight lost]) groups, and HbA1c decreased in both semaglutide (-0.54 ± SE 0.14%, P = 0.0001) and tirzepatide users (-0.68 ± SE 0.16%, P < 0.0001) over 12 months. Weight and HbA1c didn't change in controls. Conclusions: We observed weight loss of 9.1% and 21.4% and improved glucose control in semaglutide and tirzepatide users, respectively, after 1 year of off-label use. As off-label use of these drugs is increasing in patients with T1D, larger, prospective safety and efficacy trials are needed.

Aim: The real-world benefits of continuous glucose monitoring (CGM) in the broad type 2 diabetes (T2D) population are not well studied. Our study evaluated the impact of CGM use on health care resource utilization over 12 months in adults with T2D., Materials and Methods: This retrospective cohort analysis used Optum's de-identified Market Clarity data of >79 million people to evaluate CGM use in people with T2D who were treated with non-insulin (NIT), basal insulin (BIT) and prandial insulin therapy (PIT). The primary outcomes were changes in all-cause hospitalizations, acute diabetes-related hospitalizations and acute diabetes-related emergency room visits during the 6- and 12-month post-index period following transition from blood glucose monitoring to CGM. A pre-specified subgroup analysis assessed glucose control and medication changes among people with T2D over 1 year., Results: The analysis included 74 679 adults with T2D (NIT; n = 25 269), (BIT; n = 16 264) and (PIT; n = 33 146). Significant reductions in all-cause hospitalizations, acute diabetes-related hospitalizations and acute diabetes-related emergency room visits were observed in the 6-month post-index period that were sustained during the 6-12 month post-index period (NIT, -10.1%, -31.0%, -30.7%; BIT, -13.9%, -47.6%, -28.2%; and PIT, -22.6%, -52.7%, -36.6%, respectively). A subgroup analysis of 6030 people showed mean glycated haemoglobin reductions at approximately 3 months, which were also sustained throughout the post-index period: NIT, -1.1 (0.05)%; BIT, -1.1 (0.06)%; and PIT, -0.9 (0.04)%, p < 0.0001., Conclusions: CGM use in real-life across different therapeutic regimens in adults with T2D was associated with reductions in health care resource utilization with improved glucose control over 1 year., (© 2024 The Author(s).

Introduction and Objective: Most patients with type 1 diabetes (T1D) in the United States are overweight (OW) or obese (OB), contributing to insulin resistance and suboptimal glucose control. The primary Food and Drug Administration-approved treatment for T1D is insulin, which may adversely affect weight. Tirzepatide is approved for managing type 2 diabetes, improves glucose control, facilitates weight loss, and improves cardiovascular disease outcomes. We assessed the use of tirzepatide in OW/OB subjects with T1D. Methods: This was a retrospective single-center real-world study in 62 OW/OB adult patients with T1D who were prescribed tirzepatide (treated group) and followed for 1 year. At least 3 months of use of tirzepatide was one of the inclusion criteria. Based on the inclusion criteria, this study represents 62 patients out of 184 prescribed tirzepatide. The control group included 37 OW/OB patients with T1D (computer frequency matched by age, duration of diabetes, gender, body mass index (BMI), and glucose control) who were not using any other weight-loss medications during the same period. The mean (±standard deviation [SD]) dose of weekly tirzepatide at 3 months was 5.6 ± 1.9 mg that increased to 9.7 ± 3.3 mg at 1 year. Results: The gender, mean baseline age, duration of diabetes, and glycosylated hemoglobin (HbA1c) were similar in the two groups, whereas BMI and weight were higher in the treated group. There were significantly larger declines in BMI and weight in the treated group than in controls across all time points among those in whom data were available. HbA1c decreased in the treated group as early as 3 months and was sustained through a 1-year follow-up (-0.67% at 1 year). As expected, insulin dose decreased at 3 months and throughout the study period. There were no reported hospitalizations from severe hypoglycemia or diabetic ketoacidosis. The mean glucose, time-in-range, time-above-range, SD, and coefficient of variation (continuous glucose monitoring metrics) significantly improved in the treated group. Conclusions: In this pilot (off label) study, we conclude that tirzepatide facilitated an average 18.5% weight loss (>46 pounds) and improved glucose control in OW/OB patients with T1D at 1 year. For safe use of tirzepatide in patients with T1D, we strongly recommend a large prospective randomized control trial in OW/OB patients with T1D.

Aim: The impact of weight gain on insulin dosage and glycemic control in adults with type 1 diabetes (T1D) aged 25 years and older was investigated in the T1D Exchange Registry participants. Methods: Participants were categorized into four groups based on their change in weight from T1D Exchange registry enrollment to year 5: stable weight (-5 to <5 lb), gained 5 to <10 lb, gained 10 to <20 lb, or gained ≥20 lb. Those who lost >5 lb were excluded. The primary outcomes were glucose control, as measured by glycosylated hemoglobin (HbA1c), and total daily insulin dose (TDD) at year 5. Linear regression models were used to evaluate the association between weight gain, HbA1c, and TDD. Results: There were 1969 participants included in the analyses. The mean ± standard deviation age was 45 ± 13 years, 57% were female, and 92% were White non-Hispanic. For those with an enrollment HbA1c <8.0%, the mean HbA1c at year 5 was higher for those who gained ≥20 lb compared to those with a stable weight of -5 to <5 lb (7.4% ± 1.1% vs. 7.2% ± 0.8%, respectively; P  = 0.005). For this cohort, the mean TDD at year 5 increased from 49 ± 25 to 61 ± 29 U for those who gained ≥20 lb, while decreased from 45 ± 27 to 44 ± 25 U for those with stable weight of -5 to <5 lb ( P  < 0.001). Among participants with an enrollment HbA1c ≥9.0%, the mean HbA1c at year 5 was statistically insignificant at 8.4% ± 1.3% for those who gained ≥20 lb compared to 9.2% ± 1.7% for those with a stable weight of -5 to <5 lb ( P  = 0.09). Conclusion: Significant weight gain in adults with T1D who had good to adequate glycemic control was associated with modest deterioration in glucose control despite an increase in TDD. Worsening glucose control may indicate insulin resistance related to weight gain despite significantly increased insulin dosage which was insufficient to maintain adequate glycemic control.

Introduction: More than two-thirds of patients with type 1 diabetes (T1D) are overweight (OW) and/or obese (OB) in the USA and Western Europe, resulting in insulin resistance as in type 2 diabetes. None of the currently available glucagon like polypeptide 1 (GLP-1) analogs are approved for patients with T1D. A higher dose of semaglutide has been approved by the Food and Drug Administration (FDA) for subjects with body mass index (BMI) >27 kg/m 2 . We evaluated the real-world use of semaglutide in patients with T1D. Methods: This was a retrospective chart review study of 50 OW or OB patients with T1D who were initiated on semaglutide and followed for 1 year. The control group comprised of 50 computer-matched patients (for sex, race, weight, BMI, and diabetes duration) during a similar time period and were not on any weight loss medications. Results: Most patients (92%) were non-Hispanic white in both arms. Mean ± standard deviation (SD) age and duration of diabetes were 42 ± 11 and 27 ± 12 years, respectively. The continuous glucose monitors (CGM), insulin pump use, baseline BMI and body weight were also similar in the two groups. Baseline glycosylated hemoglobin (HbA1c) was insignificantly lower in the semaglutide group (7.6% vs. 8.2%, respectively; P  = non-significant [NS]). Total daily insulin dose (TDD) and insulin dose per kg body weight were higher in the semaglutide group at baseline with no difference in basal or prandial insulin dose. There were significantly greater declines in mean (±SD), BMI (7.9% ± 2.6%), body weight (15.9 lbs ± 5.4 lbs), HbA1c, CGM glucose SD and coefficient of variation (CV), and increase in CGM time in range (TIR) in the semaglutide group compared to the control group with no difference in insulin dose changes, time above range (TAR), or time below range (TBR). Conclusions: We conclude that use of semaglutide in patients who are OW and/or OB with T1D was effective in lowering body weight and BMI, and improving glycemic metrics in this pilot real-world study. We strongly recommend performing prospective, large-randomized clinical trials with newer GLP-1 analogs like semaglutide and tirzepatide (twin-cretin) for subjects with T1D associated with OW and/or OB.

Purpose: Hyporeactivity to vasopressors leading to multiple organ failure is a serious clinical implication in sepsis. Though the regulatory role of purinoceptors in inflammation is reported, their involvement in sepsis-induced vasoplegia is still unknown. Thus we investigated the effect of sepsis on vascular AT1 and P 2 Y 6 receptors., Materials and Methods: Polymicrobial sepsis was induced by cecal ligation and puncture in mice. Vascular reactivity was assessed by organ bath study and aortic mRNA expression of AT1 and P 2 Y 6 was quantified by qRT-PCR., Results: Both angiotensin-II and UDP produced higher contractions in the absence of endothelium as well as following inhibition of nitric oxide synthase. Angiotensin-II mediated aortic contraction was antagonized by losartan (AT1 antagonist), but not by PD123319 (AT2 antagonist) whereas UDP-induced aortic contraction was significantly inhibited by MRS2578 (P 2 Y 6 antagonist). In addition, MRS2578 significantly inhibited the contractile response of Ang-II. Compared to SO mice, angiotensin-II and UDP-induced maximum contraction were found to be significantly attenuated in sepsis. Accordingly, aortic mRNA expression of AT1a receptors was significantly down-regulated while that of P 2 Y 6 receptors was significantly increased in sepsis. 1400 W (a selective iNOS inhibitor) significantly reversed angiotensin-II-induced vascular hyporeactivity in sepsis without affecting UDP-induced hypo-reactivity., Conclusion: Sepsis-induced vascular hyporeactivity to angiotensin-II is mediated by enhanced expression of iNOS. Moreover, AT1R-P 2 Y 6 cross talk/heterodimerization could be a novel target for regulating vascular dysfunction in sepsis.

Aims: We aimed to determine whether plasma advanced glycation end products or oxidation products (AGE/oxidation-P) predict altered renal function and/or preeclampsia (PE) in pregnant women with type 1 diabetes., Methods: Prospectively, using a nested case-control design, we studied 47 pregnant women with type 1 diabetes, of whom 23 developed PE and 24 did not. Nineteen nondiabetic, normotensive pregnant women provided reference values. In plasma obtained at ~12, 22, and 32 weeks' gestation (visits 1, 2, and 3; V1-V3), we measured five AGE products (carboxymethyllysine (CML), carboxyethyl-lysine (CEL), methylglyoxal-hydroimidazolone (MGH1), 3-deoxyglucosone hydroimidazolone (3DGH), and glyoxal-hydroimidazolone (GH1)) and four oxidation products (methionine sulfoxide (MetSO), 2-aminoadipic acid (2-AAA), 3-nitrotyrosine (3NT), and dityrosine (DT)), by liquid chromatography/mass spectroscopy. Clinical outcomes were "estimated glomerular filtration rate" (eGFR) at each visit and onset of PE., Results: In diabetic women, associations between AGE/oxidation-P and eGFR were found only in those who developed PE. In this group, CEL, MGH1, and GH1 at V2 and CML, CEL, MGH1, and GH1 at V3 were inversely associated with contemporaneous eGFR, while CEL, MGH1, 3DGH, and GH1 at V2 were inversely associated with eGFR at V3 (all p < 0.05). There were no associations of plasma AGE or oxidation-P with pregnancy-related development of proteinuria or PE., Conclusions: Inverse associations of second and early third trimester plasma AGE with eGFR among type 1 diabetic women who developed PE suggest that these patients constitute a subset susceptible to AGE-mediated injury and thus to cardiorenal complications later in life. However, AGE/oxidation-P did not predict PE in type 1 diabetic women., Competing Interests: The authors have declared that no conflict of interest exists., (Copyright © 2023 Clare B. Kelly et al.)

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., Competing Interests: Conflict of interestRelated to this manuscript, there are no conflicts of interest for all three authors., (© Indian Institute of Science 2023, Springer Nature or its licensor (e.g. a society or other partner) holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Present study was designed to evaluate toxic effects of copper (Cu) (@ 33 mg/kg b.wt.) and flubendimide (Flb) (@ 200 mg/kg b.wt.) alone and/or in combination on blood-biochemical indices, oxidative stress, and drug metabolizing enzymes (DMEs) in vivo in male Wistar rats following oral exposure continuously for 90 days and their immunotoxic (cyto-genotoxic and apoptotic) potential in vitro on thymocytes. In in vivo study, ameliorative potential of α-tocopherol was assessed, whereas α-tocopherol, curcumin, resveratrol, and catechin were evaluated for protective effect in vitro . Significantly ( P  < 0.05) increased AST activity and increment in total bilirubin, uric acid, creatinine, and BUN levels; however, reduction in total protein, GSH content, reduced activities of SOD and GST, and increased lipid peroxidation and GPx activity with severe degenerative changes in histopathological examination of liver and kidney in group of Cu and Flb were observed. Treatment with α-tocopherol improved biochemical variables, redox status, and histoarchitecture of liver and kidney tissues. Reduced hepatic CYP 450 , CYP b5 , APH, UGT, and GST activities observed in both Cu and α-tocopherol alone and their combination groups, whereas significant increment in Flb alone, while α-tocopherol in combination with xenobiotics improved the activities of hepatic DMEs. Primary cell culture of thymocytes (10 6 cells/ml) exposed to Cu and Flb each @ 40 μM increased TUNEL +ve cells, micronuclei induction, DNA shearing, and comet formation establishes their apoptotic and genotoxic potential, whereas treatment with antioxidants showed concentration-dependent significant reduction and their order of potency on equimolar concentration (10 μM) basis is: curcumin > resveratrol > catechin = α-tocopherol., Competing Interests: There is no conflict of interests., (© The Author(s) 2023.

The significant and growing global prevalence of diabetes continues to challenge people with diabetes (PwD), healthcare providers, and payers. While maintaining near-normal glucose levels has been shown to prevent or delay the progression of the long-term complications of diabetes, a significant proportion of PwD are not attaining their glycemic goals. During the past 6 years, we have seen tremendous advances in automated insulin delivery (AID) technologies. Numerous randomized controlled trials and real-world studies have shown that the use of AID systems is safe and effective in helping PwD achieve their long-term glycemic goals while reducing hypoglycemia risk. Thus, AID systems have recently become an integral part of diabetes management. However, recommendations for using AID systems in clinical settings have been lacking. Such guided recommendations are critical for AID success and acceptance. All clinicians working with PwD need to become familiar with the available systems in order to eliminate disparities in diabetes quality of care. This report provides much-needed guidance for clinicians who are interested in utilizing AIDs and presents a comprehensive listing of the evidence payers should consider when determining eligibility criteria for AID insurance coverage., (© The Author(s) 2022.

Objective: To evaluate safety and effectiveness of MiniMed™ 670G hybrid closed loop (HCL) in comparison with continuous subcutaneous insulin infusion (CSII) therapy for 6 months in persons with type 1 diabetes (T1D). Methods: Adults (aged 18-80 years), adolescents, and children (aged 2-17 years) with T1D who were using CSII therapy were enrolled and randomized (1:1) to 6 months of HCL intervention (n = 151, mean age of 39.9 ± 19.8 years) or CSII without continuous glucose monitoring (n = 151, 35.7 ± 18.4 years). Primary effectiveness endpoints included change in A1C for Group 1 (baseline A1C >8.0%), from baseline to the end of study, and difference in the end of study percentage of time spent below 70 mg/dL (%TBR <70 mg/dL) for Group 2 (baseline A1C ≤8.0%), to show superiority of HCL intervention versus control. Secondary effectiveness endpoints were change in A1C and %TBR <70 mg/dL for Group 2 and Group 1, respectively, to show noninferiority of HCL intervention versus control. Primary safety endpoints were rates of severe hypoglycemia and diabetic ketoacidosis (DKA). Results: Change in A1C and difference in %TBR <70 mg/dL for the overall group were significantly improved, in favor of HCL intervention. In addition, a significant mean (95% confidence interval) change in A1C was observed for both Group 1 (-0.8% [-1.1% to -0.4%], P  < 0.0001) and Group 2 (-0.3% [-0.5% to -0.1%], P  < 0.0001), in favor of HCL intervention. The same was observed for difference in %TBR <70 mg/dL for Group 1 (-2.2% [-3.6% to -0.9%]) and Group 2 (-4.9% [-6.3% to -3.6%]) ( P  < 0.0001 for both). There was one DKA event during run-in and six severe hypoglycemic events: two during run-in and four during study (HCL: n = 0 and CSII: n = 4 [6.08 per 100 patient-years]). Conclusions: This RCT demonstrates that the MiniMed 670G HCL safely and significantly improved A1C and %TBR <70 mg/dL compared with CSII control in persons with T1D, irrespective of baseline A1C level.

Hyperglucagonemia contributes to hyperglycemia in patients with type 1 diabetes (T1D); however, novel therapeutics that block glucagon action could improve glycemic control. This phase 2 study evaluated the safety and efficacy of volagidemab, an antagonistic monoclonal glucagon receptor (GCGR) antibody, as an adjunct to insulin therapy in adults with T1D. The primary endpoint was change in daily insulin use at week 12. Secondary endpoints included changes in hemoglobin A1c (HbA1c) at week 13, in average daily blood glucose concentration and time within target range as assessed by continuous blood glucose monitoring (CGM) and seven-point glucose profile at week 12, incidence of hypoglycemic events, the proportion of subjects who achieve HbA1c reduction of ≥0.4%, volagidemab drug concentrations and incidence of anti-drug antibodies. Eligible participants (n = 79) were randomized to receive weekly subcutaneous injections of placebo, 35 mg volagidemab or 70 mg volagidemab. Volagidemab produced a reduction in total daily insulin use at week 12 (35 mg volagidemab: -7.59 units (U) (95% confidence interval (CI) -11.79, -3.39; P = 0.040 versus placebo); 70 mg volagidemab: -6.64 U (95% CI -10.99, -2.29; P = 0.084 versus placebo); placebo: -1.27 U (95% CI -5.4, 2.9)) without meeting the prespecified significance level (P &lt; 0.025). At week 13, the placebo-corrected reduction in HbA1c percentage was -0.53 (95% CI -0.89 to -0.17, nominal P = 0.004) in the 35 mg volagidemab group and -0.49 (95% CI -0.85 to -0.12, nominal P = 0.010) in the 70 mg volagidemab group. No increase in hypoglycemia was observed with volagidemab therapy; however, increases in serum transaminases, low-density lipoprotein (LDL)-cholesterol and blood pressure were observed. Although the primary endpoint did not meet the prespecified significance level, we believe that the observed reduction in HbA1c and tolerable safety profile provide a rationale for further randomized studies to define the long-term efficacy and safety of volagidemab in patients with T1D., (© 2022.

Aim: To investigate whether an increased bolus: basal insulin ratio (BBR) with liver-targeted bolus insulin (BoI) would increase BoI use and decrease hypoglycaemic events (HEv)., Patient Population and Methods: We enrolled 52 persons (HbA1c 6.9% ± 0.12%, mean ± SEM) with type 1 diabetes using multiple daily injections. Hepatic-directed vesicle (HDV) was used to deliver 1% of peripheral injected BoI to the liver. A 90-day run-in period was used to introduce subjects to unblinded continuous glucose monitoring and optimize standard basal insulin (BaI) (degludec) and BoI (lispro) dosing. At 90 days, BoI was changed to HDV-insulin lispro and subjects were randomized to an immediate 10% or 40% decrease in BaI dose., Results: At 90 days postrandomization, total insulin dosing was increased by ~7% in both cohorts. The -10% and -40% BaI cohorts were on 7.7% and 13% greater BoI with 6.9% and 30% (P = .02) increases in BBR, respectively. Compared with baseline at randomization, nocturnal level 2 HEv were reduced by 21% and 43%, with 54% and 59% reductions in patient-reported HEv in the -10% and -40% BaI cohorts, respectively., Conclusions: Our study shows that liver-targeted BoI safely decreases HEv and symptoms without compromising glucose control. We further show that with initiation of liver-targeted BoI, the BBR can be safely increased by significantly lowering BaI dosing, leading to greater BoI usage., (© 2022 The Authors.

Background: Standard insulin infusion sets (IISs) are to be replaced every 2 to 3 days to avoid complications and diabetic ketosis due to set failure. This pivotal trial evaluated the safety and performance of a new extended-wear infusion set (EIS) when used for 7 days by adults with type 1 diabetes (T1D). Methods: This single-arm, nonrandomized trial enrolled adults (18-80 years of age) with T1D, who used their own MiniMed™ 670G system with insulin lispro or insulin aspart and the EIS for up to 7 days, across 12 consecutive wears. Safety endpoints included incidence of serious adverse events (SAEs), serious adverse device effects (SADEs), unanticipated adverse device effects (UADEs), severe hypoglycemia (SevHypo), severe hyperglycemia (SevHyper), diabetic ketoacidosis (DKA), and skin infection. The EIS failure rate due to unexplained hyperglycemia (i.e., suspected occlusion), the overall EIS survival rate, glycemic control outcomes (i.e., A1C, mean sensor glucose and time spent in established glucose ranges), total daily insulin delivered, and satisfaction with the EIS were determined. Results: The intention to treat population ( n  = 259, 48% men, 45.0 ± 14.1 years) wore a total of 3041 EIS devices. No SADE, UADE, or DKA events was reported. Overall rates of SAEs, SevHypo, SevHyper, and skin infection were 3.8, 2.5, 104.1, and 20.1 events per 100 participant-years. The rate of EIS failure due to unexplained hyperglycemia at the end of day 7 was 0.1% (95% confidence interval [CI]: 0.03-0.51) and 0.4% (95% CI: 0.16-1.00) for insulin lispro and aspart use, respectively. Overall EIS survival rate at the end of day 7 was 77.8% (95% CI: 76.2-79.3), glycemic control did not change, and participants reported greater satisfaction with the EIS compared with standard IISs worn before the study ( P  < 0.001). Conclusions: This investigation demonstrates that the EIS, when worn for up to 7 days, was safe and rated with high satisfaction, without adversely affecting glycemic control in adults with T1D. Clinical Trial Registration number: NCT04113694 (https://clinicaltrials.gov/ct2/show/NCT04113694).

Background: We evaluated the accuracy and safety of a seventh generation (G7) Dexcom continuous glucose monitor (CGM) during 10.5 days of use in adults with diabetes. Methods: Adults with either type 1 or type 2 diabetes (on intensive insulin therapy or not) participated at 12 investigational sites in the United States. In-clinic visits were conducted on days 1 or 2, 4 or 7, and on the second half of day 10 or the first half of day 11 for frequent comparisons with comparator blood glucose measurements obtained with the YSI 2300 Stat Plus glucose analyzer. Participants wore sensors concurrently on the upper arm and abdomen. Accuracy evaluation included the proportion of CGM values within 15% of comparator glucose levels >100 mg/dL or within 15 mg/dL of comparator levels ≤100 mg/dL (%15/15), along with the %20/20 and %30/30 agreement rates. The mean absolute relative difference (MARD) between temporally matched CGM and comparator values was also calculated. Results: Data from 316 participants (619 sensors, 77,774 matched pairs) were analyzed. For arm- and abdomen-placed sensors, overall MARDs were 8.2% and 9.1%, respectively. Overall %15/15, %20/20, and %30/30 agreement rates were 89.6%, 95.3%, and 98.8% for arm-placed sensors and were 85.5%, 93.2%, and 98.1% for abdomen-placed sensors. Across days of wear, glucose concentration ranges, and rates of change, %20/20 agreement rates varied by no more than 9% from the overall %20/20. No serious adverse events were reported. Conclusions: The G7 CGM provides accurate glucose readings with single-digit MARD with arm or abdomen placement in adults with diabetes. Clinicaltrials.gov: NCT04794478.

Introduction: This trial assessed safety and effectiveness of an advanced hybrid closed-loop (AHCL) system with automated basal (Auto Basal) and automated bolus correction (Auto Correction) in adolescents and adults with type 1 diabetes (T1D). Materials and Methods: This multicenter single-arm study involved an intent-to-treat population of 157 individuals (39 adolescents aged 14-21 years and 118 adults aged ≥22-75 years) with T1D. Study participants used the MiniMed™ AHCL system during a baseline run-in period in which sensor-augmented pump +/- predictive low glucose management or Auto Basal was enabled for ∼14 days. Thereafter, Auto Basal and Auto Correction were enabled for a study phase (∼90 days), with glucose target set to 100 or 120 mg/dL for ∼45 days, followed by the other target for ∼45 days. Study endpoints included safety events and change in mean A1C, time in range (TIR, 70-180 mg/dL) and time below range (TBR, <70 mg/dL). Run-in and study phase values were compared using Wilcoxon signed-rank test or paired t -test. Results: Overall group time spent in closed loop averaged 94.9% ± 5.4% and involved only 1.2 ± 0.8 exits per week. Compared with run-in, AHCL reduced A1C from 7.5% ± 0.8% to 7.0% ± 0.5% (<0.001, Wilcoxon signed-rank test, n  = 155), TIR increased from 68.8% ± 10.5% to 74.5% ± 6.9% (<0.001, Wilcoxon signed-rank test), and TBR reduced from 3.3% ± 2.9% to 2.3% ± 1.7% (<0.001, Wilcoxon signed-rank test). Similar benefits to glycemia were observed for each age group and were more pronounced for the nighttime (12 AM-6 AM). The 100 mg/dL target increased TIR to 75.4% ( n  = 155), which was further optimized at a lower active insulin time (AIT) setting (i.e., 2 h), without increasing TBR. There were no severe hypoglycemic or diabetic ketoacidosis events during the study phase. Conclusions: These findings show that the MiniMed AHCL system is safe and allows for achievement of recommended glycemic targets in adolescents and adults with T1D. Adjustments in target and AIT settings may further optimize glycemia and improve user experience. Clinical Trial Registration number: NCT03959423.

Inhibition of Notch signaling in macrophages is known to reduce inflammation, however, its role in regulating vascular hyporeactivity in sepsis is unknown. Thus we aimed to evaluate the effect of sepsis on vascular Notch signaling. Polymicrobial sepsis was induced by caecal ligation and puncture (CLP) in mice. mRNA expressions of Notch receptors (Notch1,3) and ligands (Jag1, Dll4), and downstream effector genes (Hey1, MLCK, MYPT1) were assessed by RT-qPCR. Protein level of activated Notch (NICD) was assessed by Western blot and immuno-histochemistry. Isometric tension in isolated aortic rings was measured by wire myography.CLP down-regulated aortic expression of Notch3, Jag1 and Dll4 as compared to control mice. Additionally, the protein level of NICD was found to be lesser in aortic tissue sections from CLP mice. Expression of Hey1 and MLCK were attenuated whereas MYPT1 expression was increased in septic mouse aorta. DAPT pretreatment did not improve CLP-induced vascular hyporeactivity to NA, CaCl 2 and high K + (80 mM), rather significantly attenuated the aortic response to these vasoconstrictors in control mice. Treatment with 1400 W reversed attenuated Notch3 (but not Jag1 and MLCK) expression in septic mouse aorta. In conclusion, sepsis significantly attenuated the Notch (especially Notch3) signaling in mouse aorta along with reduction in contractile gene expression and vasoconstriction response. Further, iNOS/NO pathway was involved in sepsis-induced down-regulation of Notch3 receptor. Thus systemic inhibition of Notch signaling during sepsis may have serious impact on sepsis-induced vascular hyporeactivity., (© 2022. The Author(s).)

Background: Use of continuous glucose monitoring (CGM) systems is being rapidly adopted as standard of care for insulin-requiring patients with diabetes. The PROMISE study (NCT03808376) evaluated the accuracy and safety of the next-generation implantable Eversense CGM system for up to 180 days. Methods: This was a prospective multicenter study involving 181 subjects with diabetes at 8 USA sites. All subjects were inserted with a primary sensor. Ninety-six subjects had a second sensor, either an identical sensor or a modified sensor (sacrificial boronic acid [SBA]), inserted in their other arm (53 and 43 subjects, respectively). Accuracy was evaluated by comparing CGM to YSI 2300 glucose analyzer (Yellow Springs Instrument [YSI]) values during 10 clinic visits (day 1-180). Confirmed event detection rates, calibration stability, sensor survival, and serious adverse events (SAEs) were evaluated. Results: For primary sensors, the percent CGM readings within 20%/20% of YSI values was 92.9%; overall mean absolute relative difference (MARD) was 9.1%. The confirmed alert detection rate at 70 mg/dL was 93% and at 180 mg/dL was 99%. The median percentage of time for one calibration per day was 56%. Sixty-five percent of the primary sensors survived to 180 days. For the SBA sensors, the percent CGM readings within 20%/20% of YSI values was 93.9%; overall MARD was 8.5%. The confirmed alert detection rate at 70 mg/dL was 94% and at 180 mg/dL was 99%. The median percentage of time for one calibration per day was 63%. Ninety percent of the SBA sensors survived to 180 days. No device- or insertion/removal procedure-related SAEs were reported. Conclusion: These data show the next-generation Eversense CGM system had sustained accuracy and safety up to 180 days, with an improved calibration scheme and survival, using the primary or SBA sensors.

Atopic dermatitis (AD) is one of the most common skin diseases of dogs. Defects in the skin barrier and overproduction of inflammatory cytokines may be the pathogenesis of canine AD. Therefore, the present study was aimed to quantify the gene expression of certain skin barrier proteins and inflammatory cytokines in dogs with AD. Eleven dogs with AD and three healthy dogs were included in the present study. The skin barrier proteins, namely Filaggrin (FLG) and Involucrin (IVL), gene expression was quantified by Real-time PCR in the lesional skin tissues of the atopic dogs and normal skin of the healthy dogs. In addition to the skin proteins, the gene expressions of the interleukin (IL)-13, IL-31, and tumour necrosis factor (TNF)-α were also quantified in the peripheral blood mononuclear cells (PBMCs) of these dogs. Compared to the healthy dogs, significantly higher (P ≤ 0.01) FLG gene expression and significantly (P ≤ 0.05) lower expression of the IVL gene were quantified in the skin of atopic dogs. Further, the dogs with AD revealed significantly higher expression of TNF-α (P ≤ 0.01), IL-31 (P ≤ 0.05), and IL-13 (P ≤ 0.05) as compared to the healthy dogs. The findings of our present study evidently suggest significantly increased and decreased expressions of FLG and IVL genes, respectively, which may be responsible for disruption of the skin barrier in dogs with AD. While, the over-expressions of TNF-α, IL-31, and IL-13 genes might be attributed to the clinical pathology and manifestations of AD in dogs. However, further studies are warranted to substantiate our hypothesis about pathogenesis and clinical manifestation of AD in dogs by including a large number of animals.

The hybrid closed-loop (HCL) system has been shown to improve glycemic control and reduce hypoglycemia. Optimization of HCL settings requires interpretation of the glucose, insulin, and factors affecting glucose such as food intake and exercise. To the best of our knowledge, there is no published guidance on the standardized reporting of HCL systems. Standardization of HCL reporting would make interpretation of data easy across different systems. We reviewed the literature on patient and provider perspectives on downloading and reporting glucose metric preferences. We also incorporated international consensus on standardized reporting for glucose metrics. We describe a single-page HCL data reporting, referred to here as "artificial pancreas (AP) Dashboard." We propose seven components in the AP Dashboard that can provide detailed information and visualization of glucose, insulin, and HCL-specific metrics. The seven components include (A) glucose metrics, (B) hypoglycemia, (C) insulin, (D) user experience, (E) hyperglycemia, (F) glucose modal-day profile, and (G) insight. A single-page report similar to an electrocardiogram can help providers and patients interpret HCL data easily and take the necessary steps to improve glycemic outcomes. We also describe the optimal sampling duration for HCL data download and color coding for visualization ease. We believe that this is a first step in creating a standardized HCL reporting, which may result in better uptake of the systems. For increased adoption, standardized reporting will require input from providers, patients, diabetes device manufacturers, and regulators.

Injectable trace minerals (ITMs) could provide a potential alternative way of trace mineral delivery for sick animals. Therefore, evaluation of ameliorative potentials of ITMs (copper, manganese, selenium, and zinc) on the circulating Th1/Th2 cytokine misbalance in Theileria annulata-infected calves was aimed. Forty-three T. annulata-infected newborn calves were randomly allocated into four groups: buparvaquone alone-treated group (BUPA), buparvaquone + oxytetracycline (BUPA + OXY)-treated group, buparvaquone + injectable trace minerals (BUPA + ITMs)-treated group, and BUPA + OXY + ITM-treated group. Blood samples were collected from each of the calves before the start of therapy (day 0) and on day 14 post-therapy. Serum contents of pro- and anti-inflammatory cytokines were estimated by bovine specific ELISA kits. On day 14 post-therapy, significant amelioration in the circulating levels of the studied cytokines was not observed in the calves treated with BUPA, while the calves treated with BUPA + OXY revealed significant (P ≤ 0.04) amelioration in the circulating tumour necrosis factor-α (TNF-α) level. The calves treated with BUPA + ITMs revealed significant (P ≤ 0.041) elevation in the circulating interferon-γ (IFN-γ) and significant (P ≤ 0.011) reduction in the interleukin-10 (IL-10) levels. Moreover, the calves treated with BUPA + OXY + ITMs revealed significant reduction in TNF-α (P ≤ 0.0001) and IL-10 (P ≤ 0.012) contents, and significant elevation in IFN-γ (P ≤ 0.0002) content on day 14 post-therapy. None of the treated calve group revealed significant alteration in the circulating level of transforming growth factor-β (TGF-β) on day 14 post-therapy. In conclusion, administration of ITMs to the therapeutic regimen of newborn calves with tropical theileriosis could be a promising therapeutic strategy. ITMs can be recommended for the amelioration of immunological misbalance due to tropical theileriosis in newborn calves.

Background: Recent development and availability of several connected insulin pens with digital memory are likely to expand the availability of glucose and insulin metrics that previously had been available only for the much smaller number of people using insulin pumps. It would be highly desirable to standardize data presentations to avoid the chaotic emergence of multiple formats that might reduce the clinical utility of connected pens. Methods: We reviewed the literature and analyzed data displays from multiple blood glucose monitoring, continuous glucose monitoring (CGM), insulin pump, and automated insulin delivery systems, and methods for combination of glucose and insulin data. We examined multiple forms of presentation and now propose a prototype for a standardized method for data analysis and display, focusing on the content and format of a one-page dashboard summary for patients on multiple daily injection (MDI) insulin regimens. Results: We propose the following metrics to be included in the one-page report: (A) glucose metrics: simplified glucose distribution in the form of a stacked bar chart showing percentages of time below-, above-, or within-target ranges overall and (optionally) by date, by time of day, or day of the week; (B) insulin metrics: types and doses, and timing of basal and bolus insulin; (C) an enhanced ambulatory glucose profile or "AGP+" showing glucose data points and/or distributions (10th to 90th percentiles), dosages and timing of basal and bolus insulins and (optionally) graphical display of risk of hypoglycemia and hyperglycemia; and (D) user experience regarding technology usage, frequency of alerts for hypo- and hyperglycemia, and information regarding lifestyle, meals, exercise, and sleep, if available; and (E) clinical insights and interpretation. Conclusion: We propose a prototype for a dashboard summary report of glucose, insulin, meals, and activity data intended for providers and patients on MDI using connected pens and CGM. Our goal is to stimulate development of a standardized approach.

Background: The coronavirus disease 2019 (COVID-19) pandemic disrupted the lives of people with diabetes. Use of real-time continuous glucose monitoring (rtCGM) helped manage diabetes effectively. Some of these disruptions may be reflected in population-scale changes to metrics of glycemic control, such as time-in-range (TIR). Methods: We examined data from 65,067 U.S.-based users of the G6 rtCGM System (Dexcom, Inc., San Diego, CA) who had uploaded data before and during the COVID-19 pandemic. Users associated with three counties that included the cities of Los Angeles, Chicago, and New York or with five regions designated by the Centers for Disease Control and Prevention (CDC) were compared. Public data were used to associate regions with prepandemic and intrapandemic glycemic parameters, COVID-19 mortality, and median household income. Results: Compared with an 8-week prepandemic interval before stay-at-home orders (January 6, 2020, to March 1, 2020), overall mean (standard deviation) TIR improved from 59.0 (20.1)% to 61.0 (20.4)% during the early pandemic period (April 20, 2020 to June 14, 2020, P  < 0.001). TIR improvements were noted in all three counties and in all five CDC-designated regions. Higher COVID-19 mortality was associated with higher proportions of individuals experiencing TIR improvements of ≥5 percentage points. Users in economically wealthier zip codes had higher pre- and intrapandemic TIR values and greater relative improvements in TIR. TIR and pandemic-related improvements in TIR varied across CDC-designated regions. Conclusions: Population-level rtCGM data may be used to monitor changes in glycemic control with temporal and geographic specificity. The COVID-19 pandemic is associated with improvements in TIR, which were not evenly distributed across the United States.

The increasing prevalence of diabetes, combined with a growing global shortage of health care professionals (HCP), necessitates the need to develop new approaches to diabetes care delivery to expand access to care, lessen the burden on people with diabetes, improve efficiencies, and reduce the unsustainable financial liability on health systems and payers. Use of digital diabetes technologies and telehealth protocols within a digital/virtual diabetes clinic has the potential to address these challenges. However, several issues must be resolved to move forward. In February 2020, organizers of the Advanced Technologies & Treatments for Diabetes Annual Conference convened an international panel of HCP, researchers, patient advocates, and industry representatives to review the status of digital diabetes technologies, characterize deficits in current technologies, and identify issues for consideration. Since that meeting, the importance of using telehealth and digital diabetes technologies has been demonstrated amid the global coronavirus disease (COVID-19) pandemic. This article summarizes the panel's discussion of the opportunities, obstacles, and requisites for advancing the use of these technologies as a standard of care for the management of diabetes.

Background: Ultra rapid lispro (URLi) is a new insulin lispro formulation that has accelerated absorption and improved postprandial glucose control compared with insulin lispro (Humalog ® ). The compatibility and safety of URLi versus lispro were evaluated in patients with type 1 diabetes using continuous subcutaneous insulin infusion (insulin pump). Methods: In this phase 3, double-blind, crossover study, 49 patients were randomized to two 6-week treatment periods, after a 2-week lead-in period on lispro. The primary endpoint was the rate of infusion set failures due to a pump occlusion alarm, or unexplained hyperglycemia with blood glucose >13.9 mmol/L (250 mg/dL) that did not decrease within 1 h after a correction bolus. Results: There was no significant difference in the rate of infusion set failures between URLi and lispro (0.03 vs. 0.05 events/30 days, P  = 0.375). A higher rate of premature infusion set changes was observed with URLi (1.13 vs. 0.78 events/30 days; P  = 0.028), translating to one additional infusion set change approximately every 3 months. A trend toward improved glycemic control was observed with URLi treatment: Time in range 3.9-10.0 mmol/L (71-180 mg/dL) was 65.7% ± 1.3% versus 63.0% ± 1.3%. Treatment-emergent adverse events (TEAEs) were reported by 46.9% of patients on URLi treatment and 18.8% on lispro. This difference was driven by an increase in infusion site reactions-more than 90% were mild. Incidence of all other TEAEs and severe hypoglycemia was similar between treatments. Conclusions: URLi was compatible with insulin pump use with a safety profile similar to lispro.

The present study aimed to evaluate the pathology of the exophthalmia and the host-immune response in naturally Theileria annulata-infected calves. The newborn calves detected positive for theileriosis were grouped into calves with theileriosis and absence of exophthalmia (n = 30), and calves with theileriosis and the presence of exophthalmia (n = 13). Sixteen healthy calves, free from any haemoprotozoal infection, were kept as healthy controls. A significantly (P ≤ .001) higher circulating levels of tumour necrosis factor-α (TNF-α) and interleukin-10 (IL-10) were estimated in diseased calves with and without exophthalmia as compared to healthy controls. Contrarily, significantly (P ≤ .01) lower interferon-γ (IFN-γ) level was estimated in diseased calves. The diseased calves with exophthalmia revealed significantly higher levels of TNF-α (P ≤ .001) and IL-10 (P ≤ .006) as compared to the diseased calves without exophthalmia. The diseased calves were not found to have an elevated intraocular pressure; rather they had significantly (P ≤ .001) lower intraocular pressure compared to the healthy controls. An elevated systemic TNF-α level might be attributed to the exophthalmia in calves with tropical theileriosis. The elevated circulatory IL-10 and reduced IFN-γ levels could be one of the strategies of Theileria annulata to escape the host immunity., (© 2020 John Wiley & Sons Ltd.)

Background: The aim was to assess the safety and tolerability of the insulin aspart biosimilar/follow-on product SAR341402 (100 U/mL solution; SAR-Asp) and originator insulin aspart (100 U/mL; NN-Asp; NovoLog ® ) self-administered through an insulin pump. Materials and Methods: This randomized, open-label, 2 × 4-week crossover study enrolled 45 adults with type 1 diabetes (T1D). Participants were randomized 1:1 to the treatment sequence SAR-Asp/NN-Asp or NN-Asp/SAR-Asp. The basal and prandial insulin doses were individually titrated. The primary outcome was the number of participants with at least one infusion set occlusion (infusion set change due to failure-to-correct hyperglycemia [plasma glucose ≥250 mg/dL] by insulin pump bolus) during the 4-week treatment. The main secondary outcome was the number of participants with at least one episode of unexplained hyperglycemia (regardless of correction by an insulin pump bolus without apparent material defect, medical, dietary, insulin dosing reason, or pump problem). Results: The number of participants reporting ≥1 infusion set occlusion were similar between treatments: 14/43 on SAR-Asp (33 events) and 12/43 on NN-Asp (24 events). The estimated difference in infusion set occlusion risk for SAR-Asp versus NN-Asp was 4.1% (95% confidence interval: -9.3% to 17.4%). The number of participants with ≥1 episode of unexplained hyperglycemia was similar between treatments (31/43 on SAR-Asp [154 events]; 32/43 on NN-Asp [175 events]). Hypoglycemia, treatment-emergent adverse events, hypersensitivity, and injection site reactions were similar between treatments. Conclusions: SAR-Asp and NN-Asp were well tolerated and had similar infusion set occlusions over a 4-week period in insulin pump users with T1D.

Background: The efficacy of basal insulin (BI) for adequate glycemic control in patients with type 2 diabetes mellitus (T2DM) has been well documented by randomized clinical trials. This post hoc analysis of the Observational Registry of Basal Insulin Treatment (ORBIT) study was performed to explore the 6-month dose of BI used in insulin-naïve T2DM patients achieving HbA1c target (<7%) and determine the patient characteristics that affect the 6-month dose of BI in the setting of real-world clinics in China., Methods: This multicenter observational registry screened 19 894 adult T2DM patients with inadequately controlled hyperglycemia and treated with oral antidiabetic drugs (OADs) in China. Of these patients, 5191 who continued to receive BI after 6 months and achieved HbA1c target were analyzed. Patient characteristics including age, body weight, fasting plasma glucose (FPG), use of OADs, insulin (type and dose), and glycemic control were recorded at baseline and 6-month follow-ups., Results: The 6-month dose of BI needed for effective glycemic control was 0.20 ± 0.08 U/kg/day. High body mass index, high FPG, young age, longer duration of diabetes or OAD treatment, a greater number of OADs at baseline, and allocation to detemir and glargine were significant independent predictors for high dose of BI at 6 months., Conclusions: This post hoc analysis of the ORBIT registry provides key information on the 6-month dose of BI needed for effective glycemic control in Chinese T2DM patients. Furthermore, it identified crucial patient characteristics that are significant determinants of the dose of BI in a real-world setting., (© 2020 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.)

The risk for preeclampsia (PE) is enhanced ~4-fold by the presence of maternal type 1 diabetes (T1DM). Vitamin D is essential for healthy pregnancy. We assessed the total, bioavailable, and free concentrations of plasma 25-hydroxyvitamin D (25(OH)D), 1,25-dihydroxyvitamin D (1,25(OH) 2 D), and vitamin D binding protein (VDBP) at ~12, ~22, and ~32 weeks' gestation ("Visits" (V) 1, 2, and 3, respectively) in 23 T1DM women who developed PE, 24 who remained normotensive, and 19 non-diabetic, normotensive women (reference controls). 25(OH)D deficiency was more frequent in diabetic than non-diabetic women (69% vs. 22%, p < 0.05), but no measure of 25(OH)D predicted PE. By contrast, higher 1,25(OH) 2 D concentrations at V2 (total, bioavailable, and free: p < 0.01) and V3 (bioavailable: p < 0.05; free: p < 0.01), lower concentrations of VDBP at V3 ( p < 0.05), and elevated ratios of 1,25(OH) 2 D/VDBP (V2, V3: p < 0.01) and 1,25(OH) 2 D/25(OH)D (V3, p < 0.05) were all associated with PE, and significance persisted in multivariate analyses. In summary, in women with T1DM, concentrations of 1,25(OH) 2 D were higher, and VDBP lower, in the second and third trimesters in women who later developed PE than in those who did not. 1,25(OH) 2 D may serve as a new marker for PE risk and could be implicated in pathogenesis.

Background: SAR341402 (SAR-Asp) is a biosimilar/follow-on of the originator insulin aspart-NovoLog ® /NovoRapid ® (NN-Asp). This study investigated whether the efficacy, safety, and immunogenicity findings for SAR-Asp versus NN-Asp, observed over 6 months in people with type 1 ( n  = 497) or type 2 diabetes ( n  = 100) treated with multiple daily injections in combination with insulin glargine (Lantus ® ), are maintained after 12 months. Materials and Methods: GEMELLI 1 was a multicenter, randomized, open-label, phase 3 study. Participants completing the initial 6-month treatment period continued on SAR-Asp or NN-Asp, as randomized, for a 6-month safety extension. Results: Of the 597 participants randomized, 264 out of 301 (87.7%) and 263 out of 296 (88.9%) assigned to SAR-Asp and NN-Asp, respectively, completed 12 months of treatment. Improved glycemic control was sustained at 12 months in both treatment groups, with similar least-squares mean reductions in glycated hemoglobin (HbA1c) from baseline (SAR-Asp: -0.25%; NN-Asp: -0.26%). Fasting plasma glucose and seven-point self-monitored plasma glucose profile changes, including postprandial glucose excursions, and changes in mealtime and basal insulin dosages were similar between groups. Safety and tolerability, including anti-insulin aspart antibodies (AIAs; incidence, prevalence, titers, cross-reactivity to human insulin), neutralizing antibodies (incidence, prevalence), hypoglycemia, and treatment-emergent adverse events (including hypersensitivity events and injection site reactions), were similar between groups. No relationship was observed between maximum individual AIA titers and change in HbA1c or insulin dose, hypoglycemia, or hypersensitivity reactions or between efficacy/safety measures and subgroups by presence or absence of treatment-emergent AIA. Conclusions: SAR-Asp and NN-Asp demonstrated similar efficacy and safety (including immunogenicity) in people with diabetes over 12 months of treatment.

Background: The Stay at Home order in Colorado and The Stay Safe at Home order in California during COVID-19 pandemic have forced a majority of the endocrinologists/diabetologists to adapt to providing diabetes care remotely through telehealth. This may provide increased access to diabetes health care in certain settings. However, health care disparities continue to challenge availability of diabetes technologies for underprivileged communities. We report our experience with two patients providing diabetes care effectively and preventing hospital admissions by using telehealth. Methods: Two adult patients with type 1 diabetes (T1D): one new onset and the other one with established T1D are presented where telehealth facilitated by Clarity Software and the "Share" feature with the use of Dexcom G6 continuous glucose monitoring (CGM) for management of diabetic ketosis and hyperglycemia. Results: Both patients were managed effectively virtually despite higher risk of diabetic ketoacidosis (DKA). Shared glucose data through CGM facilitated frequent insulin dose adjustments, increased fluid and carbohydrate intake, and prevented hospital admissions in both cases. In the case of new onset patient with T1D, most of the education was done remotely by certified diabetes care and education specialists. Conclusion: Acute diabetes complication like DKA increases morbidity and mortality in addition to adding cost to the health care system. The current pandemic of COVID-19 has allowed newer ways (with the help of newer technologies) to manage high-risk patients with T1D and DKA through telehealth and may result in lasting benefits to people with T1D.

Background: The current COVID-19 pandemic provides an incentive to expand considerably the use of telemedicine for high-risk patients with diabetes, and especially for the management of type 1 diabetes (T1D). Telemedicine and digital medicine also offer critically important approaches to improve access, efficacy, efficiency, and cost-effectiveness of medical care for people with diabetes. Methods: Two case reports are presented where telemedicine was used effectively and safely after day 1 in person patient education. These aspects of the management of new-onset T1D patients (adult and pediatric) included ongoing diabetes education of the patient and family digitally. The patients used continuous glucose monitoring with commercially available analysis software (Dexcom Clarity and Glooko) to generate ambulatory glucose profiles and interpretive summary reports. The adult subject used multiple daily insulin injections; the pediatric patient used an insulin pump. The subjects were managed using a combination of e-mail, Internet via Zoom, and telephone calls. Results: These two cases show the feasibility and effectiveness of use of telemedicine in applications in which we had not used it previously: new-onset diabetes education and insulin dosage management. Conclusions: The present case reports illustrate how telemedicine can be used safely and effectively for new-onset T1D training and education for both pediatric and adult patients and their families. The COVID-19 pandemic has acutely stimulated the expansion of the use of telemedicine and digital medicine. We conclude that telemedicine is an effective approach for the management of patients with new-onset T1D.

The proliferation of Demodex mites is mainly controlled by host immunity; however, the precised mechanism of host-mite interplay and host immune response in the cutaneous microenvironment of dogs with generalized demodicosis (GD) are not yet established. In the present study, we envisaged the alterations in the expression of toll-like receptors (TLRs) and immuno-regulatory cytokine gene in the skin lesions and peripheral blood mononuclear cells (PBMCs) of dogs with GD. The expression of TLR2, TLR6, IFN-γ, TGF-β and IL-10 genes in the skin lesions and PBMCs of 15 dogs with GD was quantified by qRT-PCR. Compared to healthy dogs, significantly elevated expression of TLR2 (P = 0.048), TGF-β (P = 0.04) and IL-10 (P = 0.012) were found in the PBMCs of dogs with GD. Conversely, there was significantly reduced expression of TLR6 gene (P = 0.021) in the PBMCs of these dogs. The infested dogs also revealed significantly elevated expression of TLR2 gene (P = 0.034) in the skin lesions, while, the expression of the TLR6 gene was found to be significantly (P = 0.004) reduced. Interestingly, significant alterations in TGF-β (P = 0.105) and IL-10 (P = 0.162) genes expression were not observed in the skin lesions of diseased dogs. Our findings suggest that Demodex mites contribute to a different systemic and cutaneous immune response in dogs for their proliferation, and consequently the development of GD. Therefore, Demodex mites might be inducing the immunosuppression through activating the systemic over-expression of immunosuppressive cytokines; however, in the cutaneous lesions, the expression of immunosuppressive cytokines remained unaltered. Both systemic and local over-expression of TLR2 and reduced expression of TLR6 genes might be responsible for the inflammatory signs of canine demodicosis and helping to the mite to escape the host immunity., Competing Interests: Declaration of Competing Interest None., (Copyright © 2020 Elsevier B.V.
