Real-life Achievements of MiniMed™ 780G Advanced Closed Loop System in Youth With Type 1 Diabetes: AWeSoMe Study Group Multi-Center Prospective Trial.

We assessed real-life glycemic outcomes and predictors of composite measures of optimal glycemic control in children and adolescents with type 1 diabetes (T1D) during their initial 12 months of the MiniMed™ 780G use. This prospective observational multicenter study collected demographic, clinical, and two-week 780G system data at five timepoints. Optimal glycemic control was defined as a composite glycemic control (CGC) score requiring the attainment of four recommended continuous glucose monitoring (CGM) targets, as well as the glycemia risk index (GRI) of hypoglycemia and hyperglycemia and composite CGM index (COGI). Outcome measures included longitudinal changes in multiple glycemic parameters and CGC, GRI, and COGI scores, as well as predictors of these optimal measures. The cohort included 93 children, 43% girls, with a median age of 15.1 years [IQR 12.9,17.0]. A longitudinal analysis adjusted for age and socioeconomic index yielded a significant improvement in glycemic control for the entire cohort (ptime<0.001) after the transition to 780G. The mean HbA1c (SE) was 8.65%(0.12) at baseline and dropped by more than 1% after one year to 7.54%(0.14) (ptime<0.001). Optimal glycemic control measures improved at 12 months post 780G; CGC improved by 5.6-fold (p<0.001) and was attained by 24% of the participants, the GRI score improved by 10-fold (p=0.009) and was achieved by 10% of them, and the COGI improved by 7.6-fold (p<0.001) and was attained by 20% of them. Lower baseline HbA1c levels and increased adherence to AHCL usage were predictors of achieving optimal glycemic control. The AHCL 780G system enhances glycemic control in children and adolescents with T1D, demonstrating improvements in HbA1c and CGM metrics, albeit most participants did not achieve optimal glycemic control. This highlights yet ongoing challenges in diabetes management, emphasizing the need for continued proactive efforts on the part of healthcare professionals, youth, and caregivers.

Increasing dietary fiber intake for type 2 diabetes mellitus management: A systematic review.

Type 2 diabetes is a chronic, non-communicable disease with a substantial global impact, affecting a significant number of individuals. Its etiology is closely tied to imbalanced dietary practices and sedentary lifestyles. Conversely, increasing die-tary fiber (DF) intake has consistently demonstrated health benefits in numerous studies, including improvements in glycemic control and weight management. To investigate the efficacy of DF interventions in the management of type 2 diabetes mellitus (T2DM). A systematic literature review was conducted to explore the association between DF intake and the management of T2DM. Following the inclusion and exclusion criteria, a total of 26 studies were included in this review. The main strategies implied to increased DF intake were: High DF diet plus acarbose (2 studies); DF supplements (14 studies); and high DF diets (10 studies). Overall, most studies indicated that increased DF intake resulted in im-provements in glycemic control and weight management in T2DM patients. DF represents a valuable strategy in the treatment of type 2 diabetes, improving health outcomes. DF intake offers the potential to improve quality of life and reduce complications and mortality associated with diabetes. Likewise, through supplements or enriched foods, DF contributes significantly to the control of several markers such as HbA1c, blood glucose, triglycerides, low-density lipoprotein, and body weight.

Albumin Oxidation and Albumin Glycation Discordance During Type 2 Diabetes Therapy: Biological and Clinical Implications.

Aims: Cys34 albumin redox modifications (reversible "cysteinylation" and irreversible "di/trioxidation"), besides being just oxidative stress biomarkers, may have primary pathogenetic roles to initiate and/or aggravate cell, tissue, and vascular damage in diabetes. In an exploratory "proof-of-concept" pilot study, we examined longitudinal changes in albumin oxidation during diabetes therapy. Methods: Mass spectrometric analysis was utilized to monitor changes in human serum albumin (HSA) post-translational modifications {glycation [glycated albumin (GA)], cysteinylation [cysteinylated albumin (CA) or human non-mercaptalbumin-1; reversible], di/trioxidation (di/trioxidized albumin or human non-mercaptalbumin-2; irreversible), and truncation (truncated albumin)} during ongoing therapy. Four informative groups of subjects were evaluated [type 1 diabetes (T1DM), type 2 diabetes (T2DM), prediabetes-obesity, and healthy controls] at baseline, and subjects with diabetes were followed for a period up to 280 days. Results: At baseline, T2DM was associated with relatively enhanced albumin cysteinylation (CA% total) compared with T1DM (P = 0.004), despite comparable mean hyperglycemia (P values: hemoglobin A1c = 0.09; GA = 0.09). T2DM, compared with T1DM, exhibited selectively and significantly higher elevations of all the "individual" glycated cum cysteinylated ("multimodified") albumin isoforms (P values: CysHSA+1G = 0.003; CysHSA+2G = 0.007; and CysHSA+3G = 0.001). Improvements in glycemic control and decreases in albumin glycation during diabetes therapy in T2DM were not always associated with concurrent reductions of albumin cysteinylation, and in some therapeutic situations, albumin cysteinylation worsened (glycation-cysteinylation discordance). Important differences were observed between the effects of sulfonylureas and metformin on albumin molecular modifications. Conclusions: T2DM was associated with higher oxidative (cysteinylation) and combined (cysteinylation plus glycation) albumin molecular modifications, which are not ameliorated by improved glucose control alone. Further studies are required to establish the clinical significance and optimal therapeutic strategies to address oxidative protein damage and resulting consequences in diabetes.

The Use of SMS Text Messaging to Improve Glycemic Control, Diabetes Self-Management, and Patient Satisfaction

The prevalence of diabetes in the United States continues to grow at an alarming rate. Nonadherence to diabetes self-management leads to morbidity and mortality. Short message service (SMS) text messaging is an effective method for delivering support to increase patient engagement with diabetes self-care management. This quality improvement project evaluated the effectiveness of a unidirectional SMS text messaging intervention to improve glycemia targets in adult patients with diabetes in the primary care setting. Results showed significant improvements in glycemic control (ie, decrease in A1C of 1.04%; P = 0.05). The SMS text messaging intervention effectively supports this modality in providing ongoing motivation and support patients with diabetes.

Unveiling Pharmacokinetics and Drug Interaction of Linagliptin and Pioglitazone HCl in Rat Plasma Using LC-MS/MS.

The linagliptin (LIN) and pioglitazone HCl (PIO) combination, currently undergoing phase III clinical trials for diabetes mellitus treatment, demonstrated significant improvements in glycemic control. However, the absence of an analytical method for simultaneous determination in biological fluids highlights a crucial gap. This underscores the pressing need for sensitive bioanalytical methods, emphasizing the paramount importance of developing such tools to advance diabetes management strategies and enhance patient care. Herein, a sensitive reverse-phase high-performance liquid chromatography-electrospray ionization-tandem mass spectrometry method was developed for simultaneous determination of LIN and PIO in rat plasma using alogliptin as an internal standard. Chromatographic separation was performed on an Agilent Eclipse Plus C18 (4.6 × 100 mm, 3.5 μm) using an isocratic mobile phase system consisting of ammonium formate (pH 4.5) and methanol using an acetonitrile-induced protein precipitation technique for sample preparation. Multiple reaction monitoring in positive ion mode was used for quantitation of the precursor to production at m/z 473.2 → 419.9 for LIN, 357.1 → 134.2 for PIO, and 340.3 → 116.1 for ALO. The linearity range was 0.5 to 100 and 1 to 2000 ng/mL for LIN and PIO, respectively. The developed method was validated as per US-FDA guidelines and successfully applied to clinical pharmacokinetic and drug-drug interaction studies with a single oral administration of LIN and PIO in rat plasma. Pharmacokinetic parameters of LIN were significantly influenced by the concomitant administration of PIO and vice versa. Molecular modeling revealed the significant interaction of LIN and PIO with P-glycoprotein. Therefore, the drug-drug interaction between LIN and PIO deserves further study to improve drug therapy and prevent dangerous adverse effects.

The Effect of Telemedicine on Self-Care Activities of Patients with Type 2 Diabetes Mellitus and Patient Satisfaction During the Coronavirus-19 (COVID-19) Pandemic: A Repeated Cross-Sectional Study

Introduction: Patients with diabetes require regular follow-ups to achieve optimal glycemic targets. The coronavirus- 19 (COVID-19) pandemic resulted in interruptions in healthcare delivery placing greater importance on patient’s self-management of their condition. Telemedicine bridged the gap between the physician and patient that was created by community quarantines. Objective: To determine if there is a difference in patient’s self-care activities before and after using telemedicine using the Diabetes Self-Management Questionnaire (DSMQ). Methodology: A descriptive repeated cross-sectional study of patients with type 2 diabetes mellitus at the University of Santo Tomas Hospital who consulted via telemedicine using different available platforms were included. Self-care was measured using the DSMQ. Patient satisfaction with telemedicine was also assessed using a patient satisfaction survey. Results: An improvement in self-care practices was seen as significantly higher mean DSMQ scores after telemedicine consultations (6.79 ± 1.33 to 7.32 ± 1.21, p = 0.0015), with the highest scores on dietary control and physical activity. There was a statistically significant reduction in HbA1c on follow up (8.37 ± 2.31 to 7.31 ± 1.36; p&lt;0.00001). Those with well-controlled diabetes (n = 14) at baseline remained to have good control while the proportion of those with poorly controlled diabetes (n = 34) showed improved glycemic control on follow up (p = 0.0045). Most patients were highly satisfied with telemedicine. Conclusion: The use of telemedicine by patients with diabetes showed numerical improvement in both self-care practices and glycemic control. These findings imply that telemedicine may be mainstreamed as part of diabetes care among Filipinos. Keywords: COVID-19, telemedicine, diabetes, self-care activities

A register-based study describing time trends in risk factor control and serious hypoglycaemia together with the effects of starting continuous glucose monitoring in people with type 1 diabetes in Norway.

To describe trends in risk factor control and serious hypoglycaemia in people with type 1 diabetes and to assess the effect of starting continuous glucose monitoring (CGM) in the real-world setting. Two cross-sectional surveys including 5746 individuals in 2012 and 18,984 individuals in 2020 based on data recorded in the Norwegian Diabetes Register for Adults (NDR-A) and an analysis of a longitudinal cohort of 2057 individuals where data on CGM and HbA1c were available in the NDR-A in 2012 and 2020. In the cross-sectional surveys mean HbA1c decreased from 66 mmol/mol (99% CI 65, 66) (8.2%) in 2012 to 61 mmol/mol (99% CI 61, 61) (7.7%) in 2020 (p < 0.0001). The proportion reporting serious hypoglycaemia decreased from 16.9 to 6.2% in 2020 (p < 0.0001). Mean LDL-cholesterol decreased from 2.80 (99% CI 2.78, 2.83) to 2.63 (99% CI 2.61, 2.65) mmol/l in 2020 (p < 0.0001). Mean blood pressure increased slightly. In the CGM cohort, we found a 3 mmol/mol (0.3%) greater improvement in mean HbA1c and a greater reduction in serious hypoglycaemia (-12.3% vs. -6.2%) among individuals that had started using CGM between 2013 and 2020 when compared with individuals that had not started using CGM. Between 2012 and 2020, we found marked improvements in glycaemic control and a considerable decrease in the proportion of individuals reporting serious hypoglycaemia. The proportion of individuals using CGM increased substantially and individuals that had started using CGM by 2020 showed greater improvement in glycaemic control and less serious hypoglycaemia.

The psychosocial outcomes of advanced hybrid closed-loop system in children and adolescents with type 1 diabetes.

The study was carried out to determine the psychosocial outcomes of advanced hybrid closed-loop (AHCL) systems in children and adolescents with type 1 diabetes (T1D).Single-center and cohort study with a duration 6 months consisted of 60 children and adolescents with T1D. Standard clinical procedures, including both glycemic indicators, e.g., sensor-measured time within the 70-180 mg/dL range and glycated hemoglobin (HbA1c) levels, and psychosocial metrics were used for data collection. The psychosocial metrics included the Pediatric Quality of Life Inventory (PedsQL) 3.0 Diabetes Module for both children (8-12 years) and parents; the Quality of Life for Youth scale for adolescents (13-18 years); the Strengths and Difficulties Questionnaire (SDQ); the Hypoglycemia Fear Survey for Children (HFS-C); the Revised Child Anxiety and Depression Scale (R-CADS); and AHCLS-specific DTSEQ satisfaction and expectation survey. These metrics were evaluated at the baseline and after 6 months of AHCL use.Of the 60 children and adolescents with T1D for whom the AHCL system was utilized, 41 of them, 23 female and 18 male, completed the surveys. The mean age of the 41 children and adolescents was 12.5 ± 3.2 (min. 6.7, max. 18) years. The time spent within the target glycemic range, i.e., time-in-range (TIR), improved from 76.9 ± 9% at the baseline to 80.4 ± 5% after 6 months of AHCL system use (p = 0.03). Additionally, HbA1c levels reduced from 7.1% ± 0.7% at the baseline to 6.8% ± 0.8% after 6 months of AHCL system use (p = 0.03). The most notable decline in HbA1c was observed in participants with higher baseline HbA1c levels. All patients' HFS-C and AHCL system-specific DTSEQ satisfaction and expectation survey scores were within the normal range at the baseline and remained unchanged during the follow-up period. No significant difference was found in the R-CADS scores of children and adolescents between baseline and after 6 months of AHCL system use. However, there was a significant decrease in the R-CADS scores of the parents. Patients' PedsQL scores were high both at the baseline and after 6 months. The SDQ scores were high at baseline, and there was no significant improvement at the end of 6 months. Conclusion: This is the first study to investigate in detail the psychosocial outcomes of AHCL system use in T1D patients and their parents. Although state-of-the-art technologies such as AHCL provide patients with more flexibility in their daily lives and information about glucose fluctuations, the AHCL resulted in a TIR above the recommended target range without a change in QOL, HFS-C, SDQ, and R-CADS scores. The scores obtained from the R-CADS conducted by the parents of the children indicated that the use of pumps caused a psychological improvement in the long term, with a significant decrease in the R-CADS scores of the children and adolescents with T1D. What is Known: • Previous studies focused on clinical outcomes of AHCL systems in pediatric T1D patients, showing glycemic control improvements. • Limited attention given to psychosocial outcomes of AHCL systems in children and adolescents with T1D. • Crucial psychosocial factors like quality of life, emotional well-being, and fear of hypoglycemia underexplored in AHCL system context. What is New: • First study to comprehensively examine psychosocial outcomes of AHCL systems in pediatric T1D patients. • Study's robust methodology sets new standard for diabetes technology research and its impact on qualiy of life.

Positive Airway Pressure and Metabolic Markers in Children With Obstructive Sleep Apnea.

Increasing evidence suggests an association between childhood obstructive sleep apnea (OSA) and metabolic syndrome, with more research available on the potential impacts of positive airway pressure (PAP) on metabolic markers in children. The purpose of this systematic review is to provide a systematic synthesis of the evidence on the effect of PAP use on metabolic markers in children with OSA. A search strategy with terms for "OSA" and metabolic markers in pediatrics was run to systematically assess 5 databases until August 26, 2022. Two reviewers independently screened eligible articles, extracted data, and conducted quality appraisal. Meta-analysis was done using random-effects models. Body mass index (BMI), glycemic, lipid, cardiovascular, and other metabolic and inflammatory markers were reported. Sixteen studies (N = 1,213) were included, 15 observational studies and 1 randomized controlled trial (RCT); most reported outcomes in children with obesity. Meta-analysis of 4 studies found no changes in BMI at median average follow-up of 12 months after PAP initiation. A reduction in heart rate and blood pressure parameters was demonstrated in several studies in children with OSA with and without obesity at a median average follow-up of 4.9 months after PAP initiation. Research in echocardiographic outcomes is limited, including one RCT in children with Down syndrome and OSA showing no changes in heart rate variability parameters. Evidence of improvements in glycemic and/or lipid control, liver enzymes, and inflammatory markers with PAP therapy is even more limited and of limited clinical importance. Risk of bias was moderate to critical and outcome evidence very low. Although evidence on effects of PAP on metabolic markers in children with OSA is encouraging, available literature is limited. Longitudinal studies are still required to further assess the long-term influence of PAP on metabolic and inflammatory markers, particularly in children with obesity.

Evaluating the Efficacy, Safety, and Tolerability of Combination Therapy of Dapagliflozin and Linagliptin Over Dapagliflozin and Vildagliptin in Patients With Type 2 Diabetes Mellitus Inadequately Controlled With Metformin.

Background Type 2 diabetes mellitus (T2DM) patients commonly undergometformin monotherapy.This study aims to compare the efficacy, safety, and tolerability of combination therapy of dapagliflozin plus linagliptin versus dapagliflozin plus vildagliptin as add-on therapy in T2DM patients inadequately controlled on metformin. Methodology This was an 18-week, multicenter, randomized, double-blind, active-controlled, parallel-group, phase III clinical study. About 236 participants were randomly assigned to receive either a fixed-dose combination of dapagliflozin 10 mg plus linagliptin 5 mg tablets or a fixed-dose combination of dapagliflozin 10 mg plus vildagliptin SR 100 mg tablets added to metformin monotherapy. The primary outcome was the mean change in hemoglobin A1c (HbA1c) from baseline to the end of week 16. The key secondary endpoints were mean change in postprandial blood glucose (PPBG), fasting blood glucose (FBG), body weight, and the proportion of participants achieving HbA1c less than 7.0%. Results The dapagliflozin/linagliptin combination therapy showed a more significant change in HbA1c from baseline to the end of 16 weeks (mean reduction: -1.59% vs. -1.25%) compared to dapagliflozin/vildagliptin (p < 0.0001). Additionally, compared to the dapagliflozin/vildagliptin group, the dapagliflozin/linagliptin group demonstrated a significant reduction in both PPBG (mean reduction: -59.99 mg/dL vs. -55.34 mg/dL) and FPG (mean reduction: -32.91 mg/dL vs. -26.78 mg/dL). A total of 18 adverse events were reported in 17 (7.20%) participants, all of which were mild and resolved completely. There were no serious adverse events. Conclusions Compared to dapagliflozin and vildagliptin combination therapy, dapagliflozin and linagliptin fixed-dose combination provided clinically significant improvements in glycemic control. Because of its effectiveness, safety, and tolerability, the fixed-dose combination of dapagliflozin and linagliptin was a better option for treating T2DM patients who had previously only received metformin monotherapy.

Quality of Life and Its Association With Time in Range Among People With Type 2 Diabetes Mellitus Following Different Dietary Interventions: A Crossover Clinical Trial.

Background Quality of Life (QoL) is an essential consideration in healthcare. Numerous studies have examined QoL in India; however, data on QoL following different dietary interventions are lacking. Similarly, the use of technology such as continuous glucose monitoring (CGM) for diabetes care has independently demonstrated improvements in glycemic control; however, its association with QoL remains limited. Purpose The purpose was to study the role of different dietary interventions on QoL and its association with Time in Range (TIR), Time Above Range (TAR), and Time Below Range (TBR) among the Type 2 Diabetes Mellitus (T2DM) population. Methodology A crossover interventional clinical trial (CTRI/2022/07/044356) was conducted among participants with T2DM of less than 5 years' duration, aged between 25 and 55 years, with an HbA1c level of less than 8%, and who were on Metformin only. Their QoL was assessed after following two diet patterns: the Continuous Calorie Restricted Diet (CCRD) - calorie reduction with small frequent meals, and Time Restricted Intermittent Fasting (TRIF) - calorie reduction with only two meals a day, using the Modified QoL (MDQOL-17) questionnaire. The association between post-dietary interventions QoL and TIR was studied using a 14-day CGM device. Results The overall QoL of 51 participants at the end of the dietary interventions was significantly better compared to their QoL before any dietary intervention (85.6±19.0% and 63.1±13.0%, respectively, p = 0.000). Decreased TIR correlated with increased role limitations due to physical functioning (p = 0.002) and decreased energy levels (p = 0.00). As TBR increased, role limitation due to emotional well-being increased, and energy levels decreased significantly (p = 0.01). As TAR increased, energy levels decreased (p = 0.01). A simple linear regression model was statistically significant for role limitations due to physical functioning (p = 0.003) and energy fatigue (p = 0.000), suggesting that higher TIR is associated with higher scores in these domains. Conclusion Dietary interventions that improve the TIR and reduce the TAR and TBR can enhance the QoL of individuals with T2DM.

Glucagon-like Peptide 1, Glucose-Dependent Insulinotropic Polypeptide, and Glucagon Receptor Agonists in Metabolic Dysfunction-Associated Steatotic Liver Disease: Novel Medication in New Liver Disease Nomenclature.

Glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are incretins that regulate postprandial glucose regulation, stimulating insulin secretion from pancreatic β-cells in response to food ingestion. Modified GLP-1 receptor agonists (GLP-1RAs) are being administered for the treatment of obesity and type 2 diabetes mellitus (T2DM). Strongly related to those disorders, metabolic dysfunction-associated steatotic liver disease (MASLD), especially its aggressive form, defined as metabolic dysfunction-associated steatohepatitis (MASH), is a major healthcare burden associated with high morbidity and extrahepatic complications. GLP-1RAs have been explored in MASH patients with evident improvement in liver dysfunction enzymes, glycemic control, and weight loss. Importantly, the combination of GLP-1RAs with GIP and/or glucagon RAs may be even more effective via synergistic mechanisms in amelioration of metabolic, biochemical, and histological parameters of MASLD but also has a beneficial impact on MASLD-related complications. In this current review, we aim to provide an overview of incretins' physiology, action, and signaling. Furthermore, we provide insight into the key pathophysiological mechanisms through which they impact MASLD aspects, as well as we analyze clinical data from human interventional studies. Finally, we discuss the current challenges and future perspectives pertinent to this growing area of research and clinical medicine.

The impact of handgrip strength and waist circumference on glycemic control: Prospective, observational study using outpatient clinical data in Japanese patients with type 2 diabetes mellitus.

Loss of muscle mass and the accumulation of visceral fat are known risk factors for the deterioration of glycemic control in type 2 diabetes mellitus. This study looked at the effects of such factors on glycemic control in Japanese patients with type 2 diabetes mellitus in the form of handgrip strength (HGS) and waist circumference (WC). In this prospective, observational study, 233 patients with type 2 diabetes mellitus and a HbA1c level of ≥7.0% were followed for around 1 year, during which time they were studied for an understanding of the association between handgrip strength, waist circumference, and glycemic control (HbA1c <7.0%). Hazard ratios (HRs) and 95% confidence intervals (CIs) for glycemic control improvement by Cox hazards models were analyzed for handgrip strength and waist circumference. Compared with the low tertile, patients in the middle and high tertiles of handgrip strength when adjustment was carried out for waist circumference were 2.117 (1.142-3.924) and 4.670 (2.526-8.632), respectively. The HRs of patients in the middle and high tertiles of WC when adjustment was made for HGS were 0.442 (0.269-0.725) and 0.339 (0.191-0.604), respectively. Within the low, middle, and high HGS tertiles, the HRs for WC were 0.863 (0.797-0.934), 0.940 (0.899-0.982), and 1.009 (0.984-1.035), respectively, although the HRs for HGS within each WC tertile remained significant. Handgrip strength and waist circumference demonstrated independent associations for glycemic control, but the effect of waist circumference appeared to be at least partially canceled out by increased handgrip strength. The data suggest that handgrip strength might help to mitigate the negative impact of waist circumference on glycemic control.

The effects of Fc fusion protein glucagon-like peptide-1 and glucagon dual receptor agonist with different receptor selectivity in vivo studies

BackgroundGlucagon-like peptide-1 (GLP-1)/glucagon (GCG) dual receptor agonists with different receptor selectivity are under investigation and have shown significant improvement in both weight loss and glycemic control, but the optimal potency ratio between the two receptors to balance efficacy and safety remains unclear. Experimental approachWe designed and constructed several dual receptor agonists with different receptor potency ratios using Fc fusion protein technology. The long-term effects of the candidates on body weight and metabolic dysfunction-associated steatotic liver disease (MASLD) were evaluated in diet-induced obese (DIO) model mice, high-fat diet (HFD)-ob/ob mice and AMLN diet-induced MASLD mice. Repeat dose toxicity assays were performed to investigate the safety profile of the candidate (HEC-C070) in Sprague Dawley (SD) rats. Key resultsThe high GCG receptor (GCGR) selectivity of HEC-C046 makes it more prominent than other compounds for weight loss and most MASLD parameters but may lead to safety concerns. The weight change of HEC-C052 with the lowest GCG agonism was inferior to that of selective GLP-1 receptor agonist (GLP-1RA) semaglutide in DIO model mice. The GLP-1R selectivity of HEC-C070 with moderate GCG agonism has a significant effect on weight loss and liver function in obese mice, and its lowest observed adverse effect level (LOAEL) was 30 nmol/kg in the repeat dose toxicity study. ConclusionWe compared the potential of the Fc fusion protein GLP-1/GCG dual receptor agonists with different receptor selectivity to provide the setting for future GLP-1/GCG dual receptor agonists to treat obesity and MASLD.

Health benefits of interval walking training.

Interval walking training (IWT) is a free-living training intervention involving alternating fast and slow walking cycles. IWT is efficacious in improving physical fitness and muscle strength, and reducing factors associated with lifestyle-related diseases. In individuals with type 2 diabetes, IWT improves glycemic control directly through enhanced glucose effectiveness, challenging conventional views on mechanisms behind training-induced improvements in glycemic control. Whereas adherence to IWT in short-term studies is high, ensuring long-term adherence remains a challenge, particularly in populations with chronic diseases and/or overweight/obesity. Long-term studies in real-world settings are imperative to ascertain the widespread effectiveness of IWT and elucidate its impact on hard endpoints.

Abstract P435: Trends and Disparities in Glycemic Control Among Youth and Adults With Type 1 Diabetes in the US Health System: 2008-2022

Introduction: Glycemic control is crucial for type 1 diabetes (T1D) management, yet contemporary data in the US are scarce. This study aims to investigate trends in glycemic control among US youth and adults with T1D from 2008 through 2022. Hypothesis: Glycemic control has improved over time. Methods: We used a well-validated algorithm to identify patients with T1D using de-identified electronic health record data from the Optum Labs Data Warehouse. We characterized trends in hemoglobin A1c (HbA1c) &lt;7% from 2008-2010 to 2020-2022, overall and by age, sex, and race/ethnicity. Results: We included 128,821 patients with T1D (17% youth under age 18 years, mean age 38 years, 48% female, 78% non-Hispanic White). Among youth, mean HbA1c decreased from 8.9% in 2008-2010 to 8.5% in 2020-2022 ( P&lt;.001 ), and the percentage with HbA1c &lt;7% increased from 8% to 16% ( P&lt;.001 ). The percentage with HbA1c &lt;7% did not differ by age or sex, and it was notably higher in Non-Hispanic White youth than racial/ethnic minority youth in 2020-2022 ( Figure A-D ). Among adults, mean HbA1c decreased from 8.2% in 2008-2010 to 8.1% in 2020-2022 ( P&lt;.001 ). Trend in percentage with HbA1c &lt;7% among adults increased significantly from 20% in 2008-2010 to 26% in 2020-2022 ( P&lt;.001 ). Adults who were older and White were more likely to have HbA1c &lt;7% compared to younger and Black or Hispanic adults in all years ( Figure E-F ). Conclusion: There have been marginal improvements in glycemic control among patients with T1D over the last 15 years. Overall, percentage with HbA1c&lt;7% remains low, particularly among youth and racial/ethnic minority patients. There is an urgent need to expand access to care and diabetes technology to enhance management in the population.

Momordica charantia fruit reduces plasma fructosamine whereas stems and leaves increase plasma insulin in adult mildly diabetic obese Göttingen Minipigs.

Traditionally Momordica charantia (Bitter gourd) is known for its blood glucose lowering potential. This has been validated by many previous studies based on rodent models but human trials are less convincing and the physiological mechanisms underlying the bioactivity of Bitter gourd are still unclear. The present study compared the effects of whole fruit or stems-leaves from five different Bitter gourd cultivars on metabolic control in adult diabetic obese Göttingen Minipigs. Twenty streptozotocin-induced diabetic (D) obese Minipigs (body weight ~85 kg) were subdivided in mildly and overtly D pigs and fed 500 g of obesogenic diet per day for a period of three weeks, supplemented with 20 g dried powdered Bitter gourd or 20 g dried powdered grass as isoenergetic control in a cross-over, within-subject design. Bitter gourd fruit from the cultivars "Palee" and "Good healthy" reduced plasma fructosamine concentrations in all pigs combined (from 450±48 to 423±53 and 490±50 to 404±48 μmol/L, both p<0.03, respectively) indicating improved glycemic control by 6% and 17%. These effects were statistically confirmed in mildly D pigs but not in overtly D pigs. In mildly D pigs, the other three cultivars of fruit showed consistent numerical but no significant improvements in glycemic control. The composition of Bitter gourd fruit was studied by metabolomics profiling and analysis identified three metabolites from the class of triterpenoids (Xuedanoside H, Acutoside A, Karaviloside IX) that were increased in the cultivars "Palee" (>3.9-fold) and "Good healthy" (>8.9-fold) compared to the mean of the other three cultivars. Bitter gourd stems and leaves from the cultivar "Bilai" increased plasma insulin concentrations in all pigs combined by 28% (from 53±6 to 67±9 pmol/L, p<0.03). The other two cultivars of stems and leaves showed consistent numerical but no significant increases in plasma insulin concentrations. The effects on plasma insulin concentrations were confirmed in mildly D pigs but not in overtly D pigs. Fruits of Bitter gourd improve glycemic control and stems-leaves of Bitter gourd increase plasma insulin concentrations in an obese pig model for mild diabetes. The effects of Bitter gourd fruit on glycemic control seem consistent but relatively small and cultivar specific which may explain the varying results of human trials reported in the literature.

Herbal Nanoformulations for Diabetes: Mechanisms, Formulations, and Clinical Impact.

Diabetes mellitus remains a global health challenge, demanding innovative therapeutic strategies. Herbal remedies have garnered attention for their potential in diabetes management, and recent advancements in nanotechnology have enabled the development of herbal nanoformulations with enhanced efficacy and bioavailability. This review aimed to comprehensively analyze the mechanisms, formulations, and clinical impact of herbal nanoformulations in managing diabetes mellitus. A systematic literature search was conducted to identify relevant studies exploring the mechanisms of action, various formulations, and clinical outcomes of herbal nanoformulations in diabetes management. Herbal nanoformulations exert their anti-diabetic effects through multiple mechanisms, including enhanced bioavailability, improved tissue targeting, and potentiation of insulin signaling pathways. Various herbal ingredients, such as bitter melon, fenugreek, and Gymnema sylvestre, have been encapsulated into nanocarriers, like liposomes, polymeric nanoparticles, and solid lipid nanoparticles, to enhance their therapeutic potential. Clinical studies have demonstrated promising results, showing improvements in glycemic control, lipid profile, and antioxidant status with minimal adverse effects. Herbal nanoformulations represent a promising avenue for the management of diabetes mellitus, offering improved therapeutic outcomes compared to conventional herbal preparations. Further research is warranted to optimize formulation strategies, elucidate long-term safety profiles, and explore the potential synergistic effects of herbal nanoformulations in combination therapies for diabetes management.
