Article Abstract
Aims: To investigate the association of glycated albumin to hemoglobin A1c (GA/HbA1c) ratio, an indicator of blood glucose fluctuations, with all-cause and cardiovascular mortality among US adults.
Methods: This cohort study used data from the National Health and Nutrition Examination Survey 1999-2004. Participants were linked to National Death Index mortality data through December 31, 2015. Cox proportional hazards model was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs), and restricted cubic spline (RCS) regression was conducted.
Results: A total of 11,508 US adults (weighted mean age, 43.9 years; 5748 males [weighted, 48.9 %]) were included. During a median follow‑up of 13.6 years, 1963 total deaths occurred, including 383 cardiovascular deaths. After multivariable adjustments, a higher GA/HbA1c ratio was associated with a higher risk of all-cause (tertiles: P for trend < 0.001; continuous: HR 1.49 [95 % CI 1.32-1.69]) and cardiovascular (tertiles: P for trend = 0.048; continuous: HR 1.65 [95 % CI 1.27-2.14]) mortality. RCS revealed a linear relationship of GA/HbA1c ratio to mortality.
Conclusions: In the nationally representative cohort of US adults, GA/HbA1c ratio was significantly associated with the risk of all-cause and cardiovascular mortality. These findings suggest that GA/HbA1c ratio may serve as an effective indicator for identifying high-risk individuals.

Background: We investigated circulating protein profiles and molecular pathways among various chronic kidney disease (CKD) etiologies to study its underlying molecular heterogeneity.
Methods: We conducted a proteomic biomarker analysis in the DAPA-CKD trial recruiting adults with and without type 2 diabetes with an eGFR of 25 to 75 mL/min/1.73m2 and a UACR of 200 to 5000 mg/g.
Automated Insulin Delivery Systems and Glucose Management in Children and Adolescents With Type 1 Diabetes: A Systematic Review and Meta-Analysis.
JAMA Pediatr
September 2025
Diabetes Research Envisioned and Accomplished in Manitoba (DREAM) Research Theme, Children's Hospital Research Institute of Manitoba, Winnipeg, Canada.
Importance: Youth living with type 1 diabetes (T1D) are increasingly choosing automated insulin delivery (AID) systems to manage their blood glucose. Few systematic reviews meta-analyzing results from randomized clinical trials (RCTs) are available to guide decision-making.
Objective: To study the association of prolonged AID system use in an outpatient setting with measures of glucose management and quality of life in youth with T1D.

Graduate School of Physical Education, Myongji University, Yongin, Republic of Korea.
Background: High levels of glycated haemoglobin (HbA1c) in people with type 1 diabetes (T1D) are associated with high mortality and cardiovascular risk. Physical activity is an affordable intervention that is available to most people, but the type and amount of exercise to induce metabolic benefits in T1D are not known with certainty.
Objective: To determine the comparative effectiveness of diverse exercise modes and dosages to influence HbA1c in patients with T1D.

Aims: The estimated glucose disposal rate (eGDR) is a simple, non-invasive measure of insulin resistance. In this exploratory analysis of FINEARTS-HF, we evaluated whether lower eGDR, reflecting greater insulin resistance, is associated with adverse outcomes in heart failure (HF).
Methods And Results: The eGDR was calculated at baseline using waist circumference, glycated haemoglobin, and hypertension status.

Aims: To identify risk factors for hyperglycemia in emergency department visits within 1 year following type 2 diabetes diagnosis.
Methods: In this retrospective cohort study, electronic medical record data from 3333 adult patients newly diagnosed with type 2 diabetes across 57 primary care clinics in West Michigan between April 2021 and January 2023 were analyzed. The primary outcome was hyperglycemia at ED encounters within 12 months of diagnosis.
