Article Abstract
Plasma N-glycan profiles have been shown to be defective in type II diabetes Mellitus (T2DM) and holds a promise to discovering biomarkers. The study comprised 232 T2DM patients and 219 healthy individuals. N-glycans were analysed by high-performance liquid chromatography. The multivariate integrative framework, DIABLO was employed for the statistical analysis. N-glycan groups (GPs 34, 32, 26, 31, 36 and 30) were significantly expressed in T2DM in component 1 and GPs 38 and 20 were related to T2DM in component 2. Four clusters were observed based on the correlation of the expressive signatures of the 39 N-glycans across T2DM and controls. Cluster A, B, C and D had 16, 16, 4 and 3 N-glycans respectively, of which 11, 8, 1 and 1 were found to express differently between controls and T2DM in a univariate analysis [Formula: see text]. Multi-block analysis revealed that trigalactosylated (G3), triantennary (TRIA), high branching (HB) and trisialylated (S3) expressed significantly highly in T2DM than healthy controls. A bipartite relevance network revealed that HB, monogalactosylated (G1) and G3 were central in the network and observed more connections, highlighting their importance in discriminating between T2DM and healthy controls. Investigation of these N-glycans can enhance the understanding of T2DM.

Insulin therapy remains a cornerstone in the management of type 2 diabetes mellitus (T2DM), especially in patients experiencing progressive loss of pancreatic beta-cell function or those with inadequate glycemic control despite oral antidiabetic therapy. This review synthesized clinical outcomes from 44 peer-reviewed case reports published between 2019 and 2024, identified through systematic searches in PubMed and Scopus. The included cases involved 15 males and 29 females, with patient ages ranging from 11 to 91 years (mean 53 ± 20.

Background: The methylation of and its influence on protein stability and degradation could play a crucial role in the pathogenesis of type 2 diabetes mellitus (T2DM), although the underlying molecular mechanisms are not yet fully understood. This study investigates the molecular and bioinformatic features of methylation in T2DM.
Methods: Bioinformatics analyses were conducted on the T2DM database chip.

Objective: This study evaluates cardiac function in older adults with T2DM and preserved LVEF using two-dimensional speckle-tracking echocardiography to explore the risk factors associated with subclinical left ventricular systolic dysfunction (GLS <18%) in this population.
Methods: All patients (n = 87, aged 60 years and above) and controls (n = 20) underwent clinical assessment and echocardiography, including GLS assessment.
Results: Univariate analysis identified gender (OR 3.

Background: Epicardial adipose tissue (EAT) is an indicator of high cardiovascular and metabolic risk. This study aimed to investigate the association between EAT thickness (EATT) and liver fibrosis and steatosis in patients with type 2 diabetes mellitus (T2DM) and metabolic dysfunction-associated steatotic liver disease (MASLD).
Methods: Patients with T2DM and MASLD underwent a complex evaluation, which included clinical, laboratory, and liver and transthoracic cardiac ultrasound assessments.

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are a promising new class of drugs, whose clinical potential has recently been explored. Various preclinical studies and clinical trials initially demonstrated the efficacy of GLP-1RAs in treating type 2 diabetes mellitus (T2DM). However, long-term clinical practice has revealed that GLP-1RAs also exhibit significant efficacy and preventive effects in cardiovascular diseases.
