Engaging in diabetes self-management behaviors (SMB) is essential for optimal health outcomes. Guided by the Information, Motivation, and Behavioral Skills (IMB) model, we explored the SMB, motivations, challenges, and information needs of low-income adults living with T2D. Methods: We conducted semi-structured interviews with 17 adults recruited from the community and online. Data were analyzed using deductive and inductive thematic approaches guided by the IMB model. Results: Participants (11 females, 7 males) ages ranged from 24 to 73 years (mean: 44±18), and 100% earned <$50,000/year. T2D diagnosis duration ranged from 1-20 years. Three main themes related to SMB emerged: 1) self-directed behavioral changes amid challenges, 2) fear, support, and health aspirations drive SMB engagement, and 3) the need for tailored education and skill development for proficient self-management. Participants reported engaging in four common SMBs: dietary modifications, physical activity, medication use, and glucose monitoring using information from family, friends, the internet, and some healthcare professionals. These practices were carried out despite highlighted cultural, psychosocial, financial, and systemic barriers, including limited diabetes education and lack of insurance. Motivators included social support, a desire to improve their health, and the fear of complications, often influenced by observing severe diabetes-related complications in family and friends. Participants expressed the need to better understand T2D and more personalized, comprehensive self-management education. Conclusion: Interventions that increase access to health insurance and personalized diabetes education and strengthen social support networks may reduce disparities in low-income adults with T2D.

However, such surveillance requires a parsimonious case-finding algorithm with high predictive value. Our objective was to determine an algorithm with good performance using EHR. Methods: We conducted chart reviews of 627 Kaiser Permanente Southern California members age 18-44 years, randomly selected from a subgroup of 55,089 patients with presumed diabetes identified by any diabetes-related diagnosis code, medication, or abnormal laboratory result using EHR in 2018. With chart review as the gold standard, we compared the performance of several algorithms when defining diabetes computable phenotypes, indicated by sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). Performance was examined overall and by diabetes type, sex and race-ethnicity. Results: Identifying diabetes with diagnosis codes alone produced the best performance with sensitivity, specificity, PPV, and NPV of 94% [95% Confidence Interval: 91%-95%]; 87% (78%-93%); 98% (97%-99%) and 69% (42%-76%), respectively. When requiring a diagnosis code plus an abnormal lab or a diagnosis code plus diabetes medication, sensitivity dropped to 39% (35%-44%) and 44% (40%-49%), respectively, but specificity increased to 100%. When using a less restrictive algorithm such as requiring an abnormal lab or antidiabetic medication with a diagnosis code, sensitivity increased to 98% (97%-99%) and 97% (95%-98%), respectively, while the specificity dropped to under 50% (range: 0%-48%). Using only a diagnosis code resulted in overall good performance in identifying both T1D and T2D but the sensitivity of identified T1D was lowest among Black individuals [63% (25%-92%)]. We observed no difference in performance by sex. Conclusion: A simple algorithm using a diagnosis code only from the EHR demonstrates good performance in identifying both T1D and T2D diabetes.

Aim: To evaluate this association using SWEET registry data Methods: A cross-sectional analysis of 54,285 individuals with T1D under 25 years, diagnosed for > 3 months, from 130 SWEET centers (2022-2023). Subjects were stratified by country GDP in four groups. Key variables included HbA1c, BMI, insulin dose, use of CGM, insulin pumps, and AID. Height and BMI z-scores followed WHO references. Regression models adjusted for age, diabetes duration, and sex. Results: Height z-scores were lowest in the low GDP group (-0.44) versus +0.24 to +0.50 in higher GDP groups. BMI z-scores increased from +0.04 in the low GDP group to +0.89 in the high GDP group (p < 0.001). Insulin requirements were highest in the low GDP group (0.93 U/kg) versus 0.75-0.79 U/kg in other groups (p < 0.001). CGM use rose from 36% in the low GDP group to 91% in the high GDP group, insulin pump use from 17% to 70%, and AID systems from 11% to 38% (all p < 0.001). HbA1c was highest in the low GDP group (8.7%) and lowest in the lower-middle group (7.5%), followed by 7.7% (upper-middle) and 8.1% (high GDP). DKA was most frequent in the high GDP group, while severe hypoglycemia was most common in the low GDP group (both p < 0.001). Conclusion: A strong association exists between GDP and nutritional status, technology use, and metabolic outcomes in pediatric T1D. Best metabolic control was in countries with lower-middle or upper-middle income. High-GDP countries showed poorer control, higher BMI, and more frequent DKA. These findings stress the need for better resource allocation in pediatric diabetes care. Disclosure C. Martinez Mateu: Other Relationship; Sanofi-Aventis Argentina. S.S. Gupta: None. R.

This study evaluates the feasibility of reporting CGM utilization rates among adults with diabetes, examining uptake, variations by diabetes type, and clinician differences. Methods: A mixed-methods design assessed CGM utilization among 11,270 patients (age 18-39: 8%, 40-75: 92%; type 1: 4%, type 2: 96%) managed by 79 clinicians in 12 sites. Quantitative data included aggregated clinician results and de-identified patient uptake from automated queries of EHRs and manual chart reviews in 2023. Uptake and clinician variations were calculated using aggregated data. Feasibility was evaluated by ranking data element identification via automated queries and qualitative insights about reporting challenges. Data validity was evaluated by pooling results across sites and comparing automated queries to manual reviews, assessing sensitivity, specificity, and predictive values Results: The CGM utilization rate was 5%. Utilization was highest for type 1 diabetes (30%), followed by type 2 diabetes with multiple daily injections, basal insulin or hypoglycemic events (28%). Clinician rates varied widely, with type 1 ranging from 0% to 100% (median 25%), type 2 showing similar medians but narrower variability. Feasibility assessments highlighted challenges in identifying continuous insulin infusion users, CGM metrics, and Ambulatory Glucose Profile reports, due to unstructured documentation and inconsistent EHR capture. Validity testing showed high specificity (99%) but low sensitivity (48%), emphasizing reliance on manual reviews to ensure comprehensive and accurate data. Conclusion: CGM utilization showed significant variability across clinicians and patient groups; low adoption points to gaps in implementation despite guidelines. CGM use among individuals with type 1 diabetes was low, even though strong evidence supports its benefit. Disclosure X. Zhou: None. E. Hubbard: None. K.D. Bishop: None. E. Jun: None. N.

We have previously demonstrated the difference in the effects on insulin and incretin secretion; however, the effect on insulin sensitivity during glucose loading requires further exploration. Methods: Patients with type 2 diabetes were randomized to imeglimin group (IME) or metformin group (MET), and OGTT was performed before and after 12 and 24weeks. Insulin sensitivity was assessed by sensitivity index (SI) calculated using the oral glucose minimal model. For beta-cell function, Φb, Φd, Φs, and Φ were calculated using the oral C-peptide minimal model. Results: SI was significantly increased in both IME and MET at 24 weeks and 12 weeks, respectively. In IME, Φs and Φ were significantly increased, while only limited changes were observed in MET. Furthermore, in IME, no correlation was found between change in Φ and baseline parameters. On the other hand, in MET, change in Φ at 24 weeks was negatively corelated with baseline Φ (ρ=-0.54, p=0.01). Conclusion: Imeglimin enhanced both insulin secretion and sensitivity regardless of patients’ background, while metformin primarily improved insulin sensitivity and exerted heterogeneous effects on beta-cell function, highlighting the distinct mechanisms of action between the two drugs.

To address this gap, we explored barriers and facilitators to sleep health among this high-risk group. Methods: For this qualitative descriptive study, we conducted 45-minute semi-structured in-depth interviews with Chinese Americans living in NYC 0.5-5 years after GDM between November 2023-May 2024 until data saturation. We used thematic analysis to analyze data. Results: Participants’ (n=17) mean age was 37.9 years, 41% were 3-4 years postpartum, and 18% were breastfeeding. Most reported prolonged poor sleep after birth with insufficient sleep duration, poor quality, and/or interrupted sleep. Barriers were psychosocial (e.g., stress, anxiety), cultural (prolonged co-sleeping with kids, mom as pacifier), and environmental (e.g., noise). Facilitators included family support, a quiet living environment, and exercise. Conclusion: We found that cultural sleeping practices became major barriers to sleep health, and poor sleep health was predominant and prolonged among the study population. A culturally tailored sleep intervention that addresses cultural practices, enhances family support, reduces psychosocial and environmental barriers is needed to improve sleep health and decrease risk of T2D.

Caloric restriction (CR) and intermittent fasting (IF) improve metabolic health, but their effects on MAFLD and underlying mechanisms are unclear. This study compared CR and IF regimens in MAFLD models and explored the role of glutathione S-transferase Mu3 (GSTM3) in mediating these effects. Methods: MAFLD was induced in db/db and HFD/STZ-treated C57 mice. Animals underwent ad libitum feeding, CR, or EODF for 56 days. Metabolic parameters, liver pathology, and mitochondrial function were assessed. Transcriptomics identified GSTM3 as a key target, validated by RT-qPCR, Western blot, and immunofluorescence. CREB1 regulation of GSTM3 was confirmed by ChIP assays. Liver-specific GSTM3 overexpression was evaluated in mouse models. Results: Under matched caloric restriction conditions, both CR and EODF similarly improved body weight, liver lipid deposition, inflammatory levels, and glucose metabolism in MAFLD mice. Both CR and EODF significantly upregulated the expression of GSTM3 in the liver, mediated by the transcription factor CREB1. GSTM3 expression was reduced in MAFLD patients and animal models, while overexpression of GSTM3 significantly alleviated liver lipid accumulation, inflammation, and insulin resistance, improved mitochondrial function, and promoted fatty acid oxidation. Mechanistically, GSTM3 localized to the mitochondria, scavenged reactive oxygen species and lipid peroxides, and protected mitochondrial function. Conclusion: The intensity, rather than the type, of caloric restriction plays a key role in ameliorating MAFLD. CR upregulates GSTM3 expression in a CREB1-dependent manner, enhances mitochondrial function, and promotes fatty acid oxidation, thereby effectively improving the pathological state of MAFLD.

The role of GPD2 in energy metabolism has garnered attention from researchers, but its specific function in pancreatic β cells remains unclear. The objective of this study was to explore the role of GPD2 in pancreatic β-cells and its impact on the pathogenesis of diabetes. Methods: GPD2 expression was analyzed through population studies and the GEO database. To further validate this finding, we constructed a pancreatic β-cells specific GPD2 knockout mouse model (βGPD2KO) and utilized GPD2 pAAV-DIO overexpression virus for in vivo experiments. Additionally, we conducted GPD2 knockdown and overexpression experiments in MIN6 cells to investigate its effects on insulin secretion and apoptosis. Results: We observed a significant decline in GTT performance in βGPD2KO, indicating β-cell function impaired. Moreover, GPD2 knockdown in MIN6 cells led to a marked decrease in glucose-stimulated insulin secretion (GSIS) levels. We also found that the reduction of GPD2 was closely associated with an increase in β-cells apoptosis, as demonstrated by TUNEL staining and flow cytometry analysis. The results of RNA sequencing of pancreas islets analysis suggested that the PI3K-AKT pathway could regulate the apoptosis of β-cells. Conclusion: The loss of GPD2 negatively impacts the function of pancreatic β-cells, resulting in a decline in insulin secretion capacity and an increase in β-cells apoptosis. By modulating the expression or activity of GPD2, new avenues for the treatment of diabetic patients may be opened up. Disclosure J. Qiu: None. D. Liu: None. Y. Li: None.
