Article Abstract
Nuclear factor erythroid-2-related factor 2 (Nrf2) is a protein of the leucine zipper family, which mitigates inflammation and employs cytoprotective effects. Attempting to unravel the epigenetic regulation of type 2 diabetes mellitus (T2DM) and diabetic foot ulcer (DFU), we profiled the expression of eleven isoform-specific histone deacetylases () and correlated them with and cytokines. This study recruited a total of 60 subjects and categorized into DFU patients ( = 20), T2DM patients ( = 20), and healthy controls ( = 20). The DFU patients were subcategorized into uninfected and infected DFU ( = 10 each). We observed a progressive decline in the expression of and its downstream targets among T2DM and DFU subjects. The inflammatory markers and were significantly upregulated, whereas anti-inflammatory marker was significantly downregulated in DFU. Of note, a significant upregulation of and downregulation of among DFU patients were observed. The significant positive correlation between and in DFU patients suggested the vital role of in redox homeostasis and angiogenesis. In contrast, the significant negative correlation between and , and , implied an imbalance in circuit. Furthermore, a significant positive correlation was observed between and and the negative correlation between and suggested the pro-inflammatory role of and the anti-inflammatory role of in signaling. In conclusion, the epigenetic changes such as upregulation of and downregulation of and their association with as well as inflammatory markers are suggestive of their roles in pathophysiology of T2DM and DFU.

Background: Diabetic foot ulcers (DFUs) are a major clinical challenge, particularly among patients with refractory ulcers, that often lead to severe complications such as infection, amputation, and high mortality. Innovations supported by strong clinical evidence have the potential to improve healing outcomes, enhance quality of life, and reduce the economic burden on individuals and health care systems.
Objective: To describe the design of the concurrent optical and magnetic stimulation (COMS) therapy Investigational Device Exemption (IDE) study for refractory DFUs (MAVERICKS) trial.

Background: Diabetic foot ulcers (DFU) are a prevalent complication of diabetes, leading to significant morbidity, mortality, and amputation rates. Chronic non-healing DFU often result from peripheral neuropathy, microvascular issues, and infection, with poor blood and oxygen supply being critical factors in delayed healing. The development of new treatments to promote blood supply and accelerate ulcer healing is a significant area of research for DFU management.

Background Diabetic foot ulcers (DFUs) are a major complication of diabetes, posing significant challenges due to impaired wound healing, increased infection risk, and frequent need for surgical intervention. Optimal wound care is essential to reduce morbidity, hospital stay, and healthcare costs. While povidone iodine is a common antiseptic dressing, Metrogyl (metronidazole) targets anaerobic bacteria and may offer superior outcomes in chronic, infected wounds.

Diabetic foot ulcers (DFUs) represent a prevalent complication of diabetes, with a lifetime risk ranging from 15% to 25% among diabetic patients. Research indicates that anticoagulation plays a crucial role in the management of newly diagnosed cases of diabetic lower extremity atherosclerotic obliterative disease. However, in the present case, the patient developed dry gangrene in both toes after receiving vasodilator drugs during an emergency intervention for sudden aortic dissection.

Introduction: Charcot neuroarthropathy (CNO) of foot characterised by an increased bone turnover denoted by serological markers of bone resorption. However, histological characteristics of foot bones in people with CNO are not well elucidated.
Methods: The foot bone samples were collected from patients who had either surgical reconstruction or below-knee amputations for chronic CNO foot ( = 10, Group A), unsalvageable diabetic foot ulcer ( = 16, Group B), and non-diabetic healthy controls following road traffic accident ( = 16, group C).
