Background: Type 2 diabetes (T2D) has been linked to changes in DNA methylation levels, which can, in turn, alter transcriptional activity. However, most studies for epigenome-wide associations between T2D and DNA methylation comes from cross-sectional design. Few large-scale investigations have explored these associations longitudinally over multiple time-points.

The type 1 diabetes incidence was analyzed in 0- to 14-year-old children in North Rhine-Westphalia, Germany, from 1996 to 2022. The data revealed an overall increasing trend, with variations by age and sex. The incidence increased in boys across age groups but peaked in girls in the 5-9-year age group.

Inflammation is a probable biological pathway underlying the relationship between diabetes and depression, but data on differences between diabetes types and symptom clusters of depression are scarce. Therefore, this cross-sectional study aimed to compare associations of a multimarker panel of biomarkers of inflammation with depressive symptoms and its symptom clusters between people with type 1 diabetes (T1D) and type 2 diabetes (T2D). This cross-sectional study combined data from five studies including 1260 participants (n = 706 T1D, n = 454 T2D).

Prim Care Diabetes

January 2025

Institute for Biometrics and Epidemiology, German Diabetes Center (DDZ), Leibniz Center for Diabetes Research at Heinrich Heine University Düsseldorf, Düsseldorf, Germany; German Center for Diabetes Research (DZD), Partner Düsseldorf, Munich-Neuherberg, Germany. Electronic address:

Aims: There is a lack of studies on the impact of diabetes risk scores on diabetes prevention. The aim of this study was to investigate the effect of applying a non-invasive diabetes risk score as component of routine health checks on counselling intensity and shared decision-making (SDM) in primary care.

Methods: Cluster randomised trial, in which primary care physicians (n = 30) enrolled participants (n = 315) with statutory health insurance without known diabetes, ≥ 35 years of age with a body mass index (BMI) ≥ 27.

The aim of this work was to describe the DNA methylation signature and to identify genes associated with neuropathic pain in type 2 diabetes mellitus. We analyzed two independent diabetic neuropathy cohorts: PROPGER consisting of 72 painful and 67 painless patients recruited at the German Diabetes Center in Düsseldorf (DE), and PROPENG comprising 27 painful and 65 painless diabetic neuropathy patients recruited at the University of Manchester (UK). Genome-wide methylation data was generated using Illumina Infinium Methylation EPIC v1.

Objective: Progression of prediabetes to type 2 diabetes has been associated with β-cell dysfunction, whereas its remission to normoglycemia has been related to improvement of insulin sensitivity. To understand the mechanisms and identify potential biomarkers related to prediabetes trajectories, we compared the proteomics and metabolomics profile of people with prediabetes progressing to diabetes or reversing to normoglycemia within 1 year.

Research Design And Methods: The fasting plasma concentrations of 1,389 proteins and the fasting, 30-min, and 120-min post-oral glucose tolerance test (OGTT) plasma concentrations of 152 metabolites were measured in up to 134 individuals with new-onset diabetes, prediabetes, or normal glucose tolerance.

The athlete's paradox states that intramyocellular triglyceride accumulation associates with insulin resistance in sedentary but not in endurance-trained humans. Underlying mechanisms and the role of muscle lipid distribution and composition on glucose metabolism remain unclear. We compared highly trained athletes (ATHL) with sedentary normal weight (LEAN) and overweight-to-obese (OVWE) male and female individuals.

Background: We aimed to evaluate the incremental predictive value of metabolomic biomarkers for assessing the 10-year risk of type 2 diabetes when added to the clinical Cambridge Diabetes Risk Score (CDRS).

Methods: We utilized 86,232 UK Biobank (UKB) participants (recruited between 13 March 2006 and 1 October 2010) for model derivation and internal validation. Additionally, we included 4383 participants from the German ESTHER cohort (recruited between 1 July 2000 and 30 June 2002 for external validation).

Built-in selection or confounder bias? Dynamic Landmarking in matched propensity score analyses.

BMC Med Res Methodol

December 2024

German Diabetes Center, Leibniz Center for Diabetes Research, Institute for Biometrics and Epidemiology, Heinrich-Heine-University Düsseldorf, Düsseldorf, Germany.

Background: Propensity score matching has become a popular method for estimating causal treatment effects in non-randomized studies. However, for time-to-event outcomes, the estimation of hazard ratios based on propensity scores can be challenging if omitted or unobserved covariates are present. Not accounting for such covariates could lead to treatment estimates, differing from the estimate of interest.

Article Synopsis
  • Distal sensorimotor polyneuropathy (DSPN) is a prevalent neurological condition affecting older adults and those with obesity or diabetes, leading to significant health issues.
  • The Interpretable Multimodal Machine Learning (IMML) framework was used to predict the prevalence and incidence of DSPN by analyzing a diverse set of data from over 1,000 participants, including clinical, genomic, and metabolomic information.
  • Results showed that while clinical data alone could differentiate DSPN cases, combining it with additional molecular data improved prediction accuracy and identified potential biomarkers related to inflammation and fatty acid metabolism, offering new insights for treatment and prevention strategies.

Aims: Two prerequisites must be met for the precision treatment approach to be beneficial for treated individuals. First, there must be treatment heterogeneity; second, in case of treatment heterogeneity, clinical predictors to identify people who would benefit from one treatment more than from others must be available. There is an established meta-regression approach to assess these two prerequisites that relies on measuring the variability of a clinical outcome after treatment in placebo-controlled randomised trials.

Article Synopsis
  • Event-driven trials maintain the target power for treatment effects by focusing on obtaining a required number of events, but they may take longer if the actual event rate is lower than expected.* -
  • Blinded sample size reestimation (BSSR) uses interim data to adjust sample sizes if initial assumptions are incorrect, aiming to achieve the necessary number of events within the planned timeline.* -
  • A new flexible spline-based BSSR method, specifically the Royston-Parmar model, shows improved accuracy in predicting event counts compared to traditional parametric models, as evidenced by simulation studies and real trial applications.*

The role of exosomes for sustained specific cardiorespiratory and metabolic improvements in males with type 2 diabetes after detraining.

EBioMedicine

December 2024

Institute for Clinical Diabetology, German Diabetes Center, Leibniz Center for Diabetes Research at Heinrich-Heine University Düsseldorf, Düsseldorf, Germany; German Center for Diabetes Research, Partner Düsseldorf, München-Neuherberg, Germany; Department of Endocrinology and Diabetology, Medical Faculty and University Hospital, Heinrich-Heine-University, Düsseldorf, Germany. Electronic address:

Background: High-intensity interval training (HIIT) has been shown to improve cardiorespiratory fitness (V˙O max) but may ameliorate insulin sensitivity only in insulin-resistant humans. It is yet unclear whether these benefits persist after detraining and to which extent duration and effectiveness of metabolic improvements differ between individuals without and with prediabetes or type 2 diabetes (T2D). Understanding these differences is relevant for developing targeted exercise training modes for individuals with different stages of dysglycemia.

Aims: Weight loss mediated by glucagon-like peptide-1 (GLP-1) analogues is lower in patients with type 2 diabetes versus those without. Type 2 diabetes and obesity are risk factors for metabolic dysfunction-associated steatotic liver disease (MASLD) and associated steatohepatitis (MASH). We evaluated weight changes in adults with MASLD/MASH with or without type 2 diabetes receiving the GLP-1 analogue semaglutide.
