RESEARCH DESIGN AND METHODS A cross-sectional analysis based on data from the Diabetes-Patienten-Verlaufsdokumentation registry (Diabetes Prospective Follow-up Registry) from 2013 to 2023. Inclusion criteria were T1D, age <18 years, and at least one documented LDL measurement. LDL cut offs of >2.6, >3.4, and >4.1 mmol/L were defined. Application of national and international treatment guidelines was examined. Descriptive analyses and linear and logistic regression models were implemented using SAS 9.4. RESULTS The study included 55,028 participants. Of these, 9.7% and 2.3% had LDL >3.4 mmol/L and >4.1 mmol/L, respectively. The parameters HbA1c (β = 1,142.7; P = 0.001), female sex (β = 861.5; P < 0.001), and BMI >70th percentile (β = 520.1; P < 0.001) had the strongest effect on LDL levels. Only 7.3% of the cohort with elevated LDL levels received LLM. The majority (92.7%) with LDL >3.4 mmol/L and 87.0% with LDL >4.1 mmol/L were not treated. Estimated odds ratios (95% CI) for the use of LLM were 19.13 (15.4–23.7) for LDL >4.1 mmol/L; 3.1 (1.82–5.41) for ages 12–18 years; 2.31 (1.9–2.1) for diabetes duration of 5–10 years; 1.8 (1.5–2.1) for BMI >70th percentile; 1.3 (1.0–1.6) for HbA1c >9%; and 1.18 (1.0–1.4) for female sex. However, only 15.7% of the treated patients (n = 707) reached the LDL target of <2.6 mmol/L, and LDL levels of 55% even remained at >3.4 mmol/L. CONCLUSIONS We found a high prevalence of LDL hypercholesterolemia. The use of LLM was low, despite treatment indication, and treatment targets were mostly not achieved either due to underdosing or nonadherence to LLM. These findings confirm that dyslipidemia remains an underestimated cardiovascular risk factor in pediatric diabetology.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"21 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2026-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147470891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RESEARCH DESIGN AND METHODS In the 2-year Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy 2 (CALERIE-2) trial (n = 220), participants were randomized to 25% CR or control diet. The intervention targeted weight loss over the first 6–12 months, followed by a 12-month maintenance phase. To assess weight-regain consequences, participants were stratified by weight trajectory regardless of randomization, and group differences were balanced by propensity score weighting. Cardiometabolic and hormonal markers of available participants (n = 190), as well as a biomarker-based estimate of biological age, were compared across weight trajectory groups. RESULTS At 12 months, weight loss ranged from 5.0 to 5.8 kg between groups. Between months 12 and 24, most participants either maintained weight (n = 112) or continued to lose weight (n = 58), whereas a smaller group regained >5% of baseline weight (n = 20). This group had the largest initial caloric reductions. Weight regain reversed improvements in insulin area under the curve and the ratio of insulin-like growth factor 1 (IGF-1) to insulin-like growth factor-binding protein 1, and sustained weight loss maintained metabolic benefits and was associated with greater reductions in biological age. CONCLUSIONS Substantial weight loss followed by weight regain can attenuate or reverse CR-induced benefits on key regulators of the insulin–IGF-1 nutrient-sensing pathway and markers of biological aging. Sustained, moderate weight loss more effectively improves insulin resistance and maintains favorable hormonal profiles linked to type 2 diabetes risk and aging biology.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"11 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2026-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147465233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the accuracy, variability, and covariate bias of three glycemic biomarkers compared with glycemia measured by continuous glucose monitor (CGM) among people with and without diabetes treated with maintenance dialysis. RESEARCH DESIGN AND METHODS In a prospective community-based cohort study, 251 participants treated with maintenance dialysis wore a Dexcom G6 Pro CGM for 10 days. We compared correlations of HbA1c, glycated albumin (GA), and fructosamine with CGM-derived mean glycemia and examined sources of bias. RESULTS Participants (43% women; 63% with diabetes) had a median of 9.3 (interquartile range 8.5–9.4) valid days of CGM data. Mean (SD) HbA1c, GA, fructosamine, and mean CGM glucose were 6.2% (1.4%), 19.6% (6.3%), 351 (99) µmol/L, and 170 (63) mg/dL, respectively. HbA1c, GA, and fructosamine all strongly correlated with mean CGM blood glucose, with HbA1c and GA more correlated than fructosamine (overall, r = 0.85, r = 0.87, and r = 0.70, respectively; in diabetes, r = 0.84, r = 0.84, and r = 0.64, respectively). Compared with mean CGM glucose, HbA1c was significantly biased by erythropoiesis-stimulating agent dose, BMI, hemoglobin, and serum albumin; GA and fructosamine were biased by dialysis modality and vintage, residual kidney function, and BMI. CONCLUSIONS HbA1c and GA were strongly correlated with mean CGM blood glucose, but all biomarkers had substantial bias by relevant clinical characteristics. HbA1c and GA may be useful assessments of average glycemia in patients treated with maintenance dialysis, if bias can be adequately addressed.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"80 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2026-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147383341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RESEARCH DESIGN AND METHODS Two target trial emulations included commercially insured adults (June 2022–December 2024) with T2D and ASCVD who initiated subcutaneous tirzepatide, dulaglutide, or semaglutide. The primary outcome was modified major adverse cardiovascular events (MACE), defined as a composite of nonfatal myocardial infarction, nonfatal stroke, and all-cause death. First, new users of tirzepatide and dulaglutide were propensity score (PS) matched one to one. Second, new users of tirzepatide and semaglutide were PS matched one to one. Incidence rates (IRs) per 1,000 person-years and hazard ratios (HRs) were estimated. RESULTS After PS matching, 9,233 pairs of tirzepatide or dulaglutide initiators and 25,266 pairs of tirzepatide or semaglutide initiators were identified. Tirzepatide initiators experienced a lower rate of modified MACE versus dulaglutide initiators (IR 31.3 vs. 39.4, respectively; HR 0.80 [95% CI 0.65–0.99]), which seemed to be driven by lower all-cause mortality among tirzepatide versus dulaglutide initiators (HR 0.60 [95% CI 0.43–0.83]). In post hoc analyses, tirzepatide was associated with lower rates of pneumonia-related hospitalization when compared with dulaglutide.

RESEARCH DESIGN AND METHODS In this 30-week, double-blind trial, 154 participants were randomized to semaglutide (n = 77) or placebo (n = 77); 141 (91.5%) completed the study. Baseline and end-of-study assessments included fasting glucose, insulin, C-peptide, HOMA2 of β-cell function, HOMA2 of insulin sensitivity, HOMA of insulin resistance, and body weight. RESULTS Participants (56% women, mean age 38.3 years) provided complete insulin data in 131 cases. Compared with placebo, semaglutide significantly reduced fasting glucose (−0.87 mmol/L [95% CI −1.15, −0.59]; P < 0.001), improved insulin sensitivity (8.60 [5.82, 13.65]; P = 0.001), and lowered insulin resistance (−0.69 [−1.00, −0.20]; P = 0.006). Mean weight loss was 9.2 kg and mediated improvements in insulin sensitivity (estimate 7.82; P = 0.01) and insulin resistance (estimate −0.75; P = 0.01).

Glycemic management trajectories (optimal ≥80% of glucose values meeting American Diabetes Association targets) were identified from GDM diagnosis to delivery. Associations with offspring BMI and obesity risk were estimated using adjusted generalized estimating equations. RESULTS Among 206,464 pregnant individuals, 14,870 (7.2%) had GDM; among whom four glycemic management trajectories were identified: stably optimal (T1), rapidly improving to optimal (T2), slowly improving to near optimal (T3), and slowly improving to suboptimal (T4). Associations showed a dose-response pattern across T1–T4. By age 10, offspring in T1 had BMI (β = 0.27 [95% CI −0.13, 0.66]) and obesity risk (risk ratios 1.07 [0.91, 1.26]) similar to those unexposed to GDM.

Insulin requirements dropped from 0.75 (IQR = 0.58, 1.00) units/kg/day to 0.32 (IQR = 0.23, 0.43) units/kg/day (P < 0.001), and HbA1c from 64.0 (IQR = 57.0, 74.0) mmol/mol to 60.0 (IQR = 53.4, 68.0) mmol/mol (P < 0.001). LDL, HDL, total cholesterol, and triglyceride levels significantly improved after surgery (P < 0.001). Greater total weight loss was associated with reduced insulin requirements, and higher baseline HbA1c was associated with poorer postsurgery glycemic control. CONCLUSIONS MBS was associated with substantial metabolic improvement in people with T1D and obesity, in particular in those with high HbA1c and insulin need at baseline.","PeriodicalId":11140,"journal":{"name":"Diabetes Care","volume":"180 1","pages":""},"PeriodicalIF":16.2,"publicationDate":"2026-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146215706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
