In recent years, advances in optical coherence tomography (OCT) techniques have increased our understanding of diabetic retinopathy, an important microvascular complication of diabetes. OCT angiography is a non-invasive method that visualizes the retinal vasculature by detecting motion contrast from flowing blood. Visible-light OCT shows promise as a novel technique for quantifying retinal hypoxia by measuring the retinal oxygen delivery and metabolic rates. In this article, we discuss recent insights provided by these techniques into the vascular pathophysiology of diabetic retinopathy. The next milestones for these modalities are large multicenter studies to establish consensus on the most reliable and consistent outcome parameters to study diabetic retinopathy.

Aim: This study aimed to explore the association between the ratio of 4-pyridoxine (4-PA) to pyridoxal 5'-phosphate (PLP) (4-PA/PLP) and diabetic retinopathy (DR) and further assess the mediating effect of Endothelial Activation and Stress Index (EASIX) on the association between 4-PA/PLP and DR.
Methods: In this cross-sectional study, 1,698 patients with diabetes from the National Health and Nutrition Examination Survey were included. According to the median, 4-PA/PLP was categorized into a high-level group (≥0.

This study aimed to the investigate prevalence and factors associated with reduced skeletal muscle mass in non-elderly adults with type 1 diabetes (T1D). Ninety-nine patients (65 women, mean age: 43 ± 11 years, range 20-65 years) with acute-onset T1D who underwent body component analysis between October 2016 and April 2018 were studied. Bioelectrical impedance analysis was used to calculate the skeletal muscle mass index (SMI) of the limbs.

This study explored the role of dentate status and dental caries on diabetes-related complications among patients with type 2 diabetes mellitus (T2DM). A hospital-based cross-sectional design was applied to collect data on diabetic patients attending integrated services for non-communicable diseases and oral health at a public hospital in Thailand. Diabetic complication outcomes included diabetic eye and foot complications and chronic kidney disease (CKD).

Aims/hypothesis: Within the small intestine, neutrophils play an integral role in preventing bacterial infection. Upon interaction with bacteria or bacteria-derived antigens, neutrophils initiate a multi-staged response of which the terminal stage is NETosis, formation of protease-decorated nuclear DNA into extracellular traps. NETosis has a great propensity to elicit ocular damage and has been associated with diabetic retinopathy and diabetic macular oedema (DME) progression.
