Article Synopsis
  • The text reviews clinical evidence on systemic factors that could help improve diabetic retinal disease (DRD) staging systems, focusing on predicting the onset, progression, and treatment responses of the disease.
  • Key findings indicate that longer diabetes duration, higher HbA1c levels, and male sex are linked to increased DRD risk, while blood pressure is also a significant factor in both incidence and progression.
  • Despite some associations, multivariate models showed that retinal measures are better predictors of DRD progression than systemic factors, and comprehensive studies validating the prognostic value of treatments are still needed.

Background/objective: Prolonged heart rate-corrected QT interval (QTc) on the electrocardiogram (ECG) is maybe associated with the occurrence of cardiovascular diseases (CVD), but the evidence is inconsistent. Therefore, we investigated whether baseline prolongation of the QTc interval is associated with CVD morbidity and mortality and its subtypes and whether glucose tolerance modifies this association in a population-based cohort study with a mean follow-up of 10.8 years.

Background The association between common carotid artery intima-media thickness (CCA-IMT) and incident carotid plaque has not been characterized fully. We therefore aimed to precisely quantify the relationship between CCA-IMT and carotid plaque development. Methods and Results We undertook an individual participant data meta-analysis of 20 prospective studies from the Proof-ATHERO (Prospective Studies of Atherosclerosis) consortium that recorded baseline CCA-IMT and incident carotid plaque involving 21 494 individuals without a history of cardiovascular disease and without preexisting carotid plaque at baseline.

We identify biomarkers for disease progression in three type 2 diabetes cohorts encompassing 2,973 individuals across three molecular classes, metabolites, lipids and proteins. Homocitrulline, isoleucine and 2-aminoadipic acid, eight triacylglycerol species, and lowered sphingomyelin 42:2;2 levels are predictive of faster progression towards insulin requirement. Of ~1,300 proteins examined in two cohorts, levels of GDF15/MIC-1, IL-18Ra, CRELD1, NogoR, FAS, and ENPP7 are associated with faster progression, whilst SMAC/DIABLO, SPOCK1 and HEMK2 predict lower progression rates.

Article Synopsis
  • Sudden cardiac death accounts for 10% to 20% of deaths in Europe, prompting research to improve prediction models for at-risk individuals.
  • The study used data from the Copenhagen City Heart Study (CCHS) and the Hoorn Study to validate an existing model originally developed in the USA, assessing its performance through various statistical methods.
  • Findings revealed the model had good discrimination (C-statistic of 0.81) and robust calibration, but a low positive predictive value, indicating it might not effectively identify all individuals at risk in the North-West European population.

Purpose Of Review: We aimed to systematically evaluate the content validity of patient-reported outcome measures (PROMs) specifically developed to measure (aspects of) health-related quality of life (HRQOL) in people with type 2 diabetes. A systematic review was performed in PubMed and Embase of PROMs measuring perceived symptoms, physical function, mental function, social function/participation, and general health perceptions, and that were validated to at least some extent. Content validity (relevance, comprehensiveness, and comprehensibility) was evaluated using COSMIN methodology.

Aims: Valid health economic models are essential to inform the adoption and reimbursement of therapies for diabetes mellitus. Often existing health economic models are applied in other countries and settings than those where they were developed. This practice requires assessing the transferability of a model developed from one setting to another.

Article Synopsis
  • - The study focuses on the significant issue of sudden cardiac death (SCD) affecting many individuals, even those without apparent risk factors, and seeks to standardize the definition and classification of SCD for research purposes.
  • - It establishes harmonized case definitions for SCD using multiple data sources and a register-based method, validating this approach against a comprehensive standard using factors like sensitivity and specificity.
  • - The research successfully reached a consensus on classifying SCD cases as "definite," "possible," and "probable," indicating that a standardized method can support better SCD studies and allow comparison across different research cohorts.

Introduction: Although associations of total plasma glycome (TPNG) with type 2 diabetes have been reported, little is known on the role of TPNG in type 2 diabetes complications, a major cause of type 2 diabetes-related morbidity and mortality. Here, we assessed TPNG in relation to type 2 diabetes complications in subsamples of two Dutch cohorts using mass spectrometry (n=1815 in DiaGene and n=1518 in Hoorn Diabetes Care System).

Research Design And Methods: Blood plasma samples and technical replicates were pipetted into 96-well plates in a randomized manner.

Introduction: Early recognition of individuals with increased risk of sudden cardiac arrest (SCA) remains challenging. SCA research so far has used data from cardiologist care, but missed most SCA victims, since they were only in general practitioner (GP) care prior to SCA. Studying individuals with type 2 diabetes (T2D) in GP care may help solve this problem, as they have increased risk for SCA, and rich clinical datasets, since they regularly visit their GP for check-up measurements.
