Article Abstract
Skin exhibits limited self-regenerative capacity following an injury; therefore, it is imperative to develop appropriate wound dressings capable of expediting postinjury closure to prevent microbial invasion and enhance the wound healing process. In this study, poly--isopropylacrylamide (PNI), sodium dodecyl sulfate/octadecyl methacrylate micellar (SA), and micellar (chitin/lignin)-loaded curcumin (Cur) were used for constructing a thermosensitive and tissue-adhesive hydrogel (PNI-SA@Cur), aiming to develop a wound dressing that enhanced wound healing. The results demonstrated that PNI-SA@Cur hydrogel exhibited superior thermal shrinkability, along with excellent adhesion and self-healing capabilities, and it also showed good hemocompatibility and cytocompatibility. Additionally, PNI-SA@Cur as a sealant significantly achieved suture-free postwound closure in the early stages of wound healing, and it demonstrated a substantial capacity to promote wound healing by reducing inflammatory cell infiltration, facilitating favorable collagen deposition, and stimulating abundant angiogenesis. The thermoresponsive and tissue-adhesive hydrogel dressing represents a promising material for promoting wound healing.

Background: Current management of pediatric cutaneous abscesses involves either spontaneous healing by secondary intention or suturing through tertiary intention, which are often lengthy processes that cause discomfort and distress among children. As it is noninvasive and simple, a novel zipper device is widely used for the primary wound closure of surgical incisions.
Objective: To describe the effectiveness of novel zipper device use for pediatric cutaneous abscess wound closure in an outpatient context.
Background: This retrospective analysis is a derivative cohort study based on a prior retrospective investigation by this author group.
Objective: To assess the effect of the number of cellular and/or tissue-based product (CTP) applications on healing outcomes and wound area reduction (WAR) rates in patients with chronic wounds of multiple etiologies.
Methods: Data from a multicenter private wound care practice electronic health record database were analyzed for Medicare patients receiving CTPs from January 2018 through December 2023.

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.
