Article Abstract
Aims: Glycated albumin (GA) is a biomarker, whose level reflects glycemic control status over the previous 2 weeks. To develop a non-invasive method for evaluating glycemic control in people with diabetes mellitus, we investigated the measurement of GA levels in tears and saliva, which could be collected noninvasively.
Methods: Tear and saliva samples were collected from 48 participants with diabetes mellitus. The GA levels in the tear and saliva specimens were measured by Liquid Chromatography-Mass Spectrometry (LC-MS/MS).
Results: GA levels in both tear and saliva samples were significantly correlated with the GA levels in the blood (P < 0.001). Multiple regression analysis revealed that these correlations were maintained even after adjustments for the BMI, age, and nephropathy stage (P < 0.001).
Conclusion: GA levels in tear and saliva specimens, as diabetes-related biomarkers, can be measured non-invasively. Since this measurement can be performed noninvasively and not as frequently as compared with the more invasive finger prick method, it is expected to reduce the burden on people with diabetes in terms of both the invasiveness and cost-effectiveness. In the future, we would like to verify the effect of regular GA measurement on the glycemic control while considering the clinical cost-effectiveness.

Background: Chronic kidney disease (CKD) management was largely centered around renin-angiotensin-aldosterone system inhibitors (RAASi) optimization, until recent emergence of novel therapeutics. However, slow adoption of guideline-directed therapy leaves patients vulnerable to disease progression. In 2022, a data-driven informatics approach was introduced to track real-time adherence to best practices.

Background: The long-term clinical efficacy of intraportal islet transplantation is hampered by islet loss due to inflammation, oxidative stress, and insufficient vascularization. This study explores the venous sac as an alternative implantation site for islet transplantation in large animal models.
Methods: An immunosuppressed, diabetic cynomolgus monkey received allogeneic islet implants in its mesenteric venous sac, with metabolic assessments over 112 days.

Background: Diabetic foot ulcer (DFU) represents a challenging complication of diabetes mellitus, characterized by slow healing processes. Protein kinase C delta (PKCδ) has been identified as a significant factor in the pathogenesis of various diabetic complications, including DFU. However, the precise underlying mechanisms remain to be fully elucidated.

For individuals with diabetes, maintaining optimal glycaemic control is essential to reduce the risk of long-term complications. However, as patients approach the end of life, the emphasis on tight glycaemic targets becomes less relevant. Instead, the primary goal shifts to maintaining blood glucose levels within a range that minimises the risk of hypoglycaemia and prevents symptomatic hyperglycaemia, thereby ensuring comfort and quality of life.

Background: Postoperative complications significantly impact outcomes in head and neck free-flap reconstruction. The comprehensive complication index (CCI) offers a continuous measure of complication burden but is rarely applied in head and neck surgery compared to the Clavien-Dindo Classification (CDC).
Methods: This retrospective study analyzed 354 patients who underwent head and neck free-flap reconstruction.
