The current clinical treatment of diabetic wounds is still based on oxygen therapy, and the slow healing of skin wounds due to hypoxia has always been a key problem in the repair of chronic skin injuries. To overcome this problem, the oxygen-producing matrix CaONPS based on the temperature-sensitive dihydromyricetin-loaded hydrogel was prepared. In vitro activity showed that the dihydromyricetin (DHM) oxygen-releasing temperature-sensitive hydrogel composite (DHM-OTH) not only provided a suitable oxygen environment for cells around the wound to survive but also had good biocompatibility and various biological activities. By constructing a T2D wound model, we further investigated the repairing effect of DHM-OTH on chronic diabetic skin wounds and the mechanisms involved. DHM-OTH was able to reduce inflammatory cells and collagen deposition and promote angiogenesis and cell proliferation for diabetic wound healing. These in vitro and in vivo data suggest that DHM-OTH accelerates diabetic wound repair as a novel method to efficiently deliver oxygen to wound tissue, providing a promising strategy to improve diabetic wound healing.

Background/aim: Hydrogen therapy has demonstrated potential as an antioxidant and anti-inflammatory intervention, particularly in the management of chronic diseases such as chronic kidney disease (CKD) and autoimmune conditions. This case report presents the possible therapeutic benefits of molecular hydrogen capsule treatment in enhancing renal function and alleviating chronic fatigue in an elderly female with coronary artery disease (CAD), type 2 diabetes mellitus (DM) complicated by nephropathy, and systemic lupus erythematosus (SLE). The aim of this study was to investigate the efficacy of adjunctive hydrogen therapy in an elderly patient with multiple chronic comorbidities.

Background: Phage therapy offers a promising alternative for treating serious infections, including diabetic foot ulcers (DFUs), through the lytic action of phages. This randomized double-blind study was conducted to evaluate the safety and tolerability of the TP-102 bacteriophage cocktail in patients with DFUs non-infected and infected with Staphylococcus aureus, Pseudomonas aeruginosa, and/or Acinetobacter baumannii.

Methods: Nineteen participants with DFUs were randomized after susceptibility testing.

Three-dimensional bioprinting is getting enormous attention among the scientific community for its application in complex regenerative tissue engineering applications. One of the focus areas of 3-D bioprinting is Skin tissue engineering. Skin is the largest external organ and also the outer protective layer is prone to injuries due to accidents, burns, pathologic diseases like diabetes, and immobilization of patients due to other health conditions, etc.

Background: Oral ulcers are painful mucosal lesions prone to infection and inflammation. To evaluate the effectiveness of treatments, a suitable experimental animal model with an appropriate healing period is required. The aim of this study was to develop an animal model for oral ulcer research by comparing oral burn wounds of different sizes and locations in diabetic rats.

Wolcott-Rallison Syndrome is an extremely rare syndrome characterized by infantile non-autoimmune diabetes, extensive skeletal dysplasia, and multi-organ failure requiring transplant. Prognosis is very poor, and as such, surgical intervention for symptomatic cervical spine compromise in pediatric patients has not been widely reported in part due to their high fragility. We report a complex case of Wolcott-Rallison Syndrome that presented with cervical myelopathy due to cervicomedullary compression and the exceptional surgical considerations required for successful intervention.
