Type 2 diabetes is associated with several potential comorbidities, among them impaired wound healing, chronic ulcerations, and the requirement for lower extremity amputation. Disease-associated abnormal cellular responses, infection, immunological and microvascular dysfunction, and peripheral neuropathy are implicated in the pathogenesis of the wound healing impairment and the diabetic foot ulcer. The skin houses a dense network of sensory nerve afferents and nerve-derived modulators, which communicate with epidermal keratinocytes and dermal fibroblasts bidirectionally to effect normal wound healing after trauma. However, the mechanisms through which cutaneous innervation modulates wound healing are poorly understood, especially in humans. Better understanding of these mechanisms may provide the basis for targeted treatments for chronic diabetic wounds. This review provides an overview of wound healing pathophysiology with a focus on neural involvement in normal and diabetic wound healing, as well as future therapeutic perspectives to address the unmet needs of diabetic patients with chronic wounds.

Penetrating orocutaneous or oropharyngeal fistulas (POFs), severe complications following unsuccessful oral or oropharyngeal reconstruction, remain complex clinical challenges due to lack of supportive tissue, contamination with saliva and chewed food, and dynamic oral environment. Here, we present a Janus hydrogel adhesive (JHA) with asymmetric functions on opposite sides fabricated via a facile surface enzyme-initiated polymerization (SEIP) approach, which self-entraps surface water and blood within an in-situ formed hydrogel layer (RL) to effectively bridge biological tissues with a supporting hydrogel (SL), achieving superior wet-adhesion and seamless wound plugging. The tough SL hydrogel interlocked with RL dissipates energy to withstand external mechanical stimuli from continuous oral motions like chewing and swallowing, thus reducing stress-induced damage.

Despite the variety of proposed solutions, anastomotic leakage is still a critical complication after colorectal surgery, which causes increased clinical mortality and morbidity. By enhancing microcirculation in the colonic mucosa, the use of Iloprost (Ilo) has shown promising results for the healing of anastomosis. The purpose of this study is to examine the performance of Ilo-impregnated Polycaprolactone:Gelatin electrospun membranes (PCL/Gel/Ilo) on anastomosis repair and intra-abdominal adhesion behavior in the Rat colon.

IntroductionProlonged hyperglycemia in diabetic patients often impairs wound healing, leading to chronic infections and complications. This study aimed to evaluate the potential of fresh Tilapia fish skin as a treatment to enhance wound healing in diabetic rats. MethodsThirty-nine healthy adult albino rats, weighing between 150 and 200 g, were divided into three groups: non-diabetic rats with untreated wounds [C-], diabetic rats with untreated wounds [C+], and diabetic rats treated with fresh Tilapia skin [TT].
