Smart wound dressings aim to enable early diagnosis and treatment of wound infections to accelerate wound healing. This paper summarizes the latest research progress of smart wound dressings, including smart dressings for monitoring different parameters of wounds, smart dressings that can realize wound management, and advanced smart wound dressings that integrate monitoring and treatment into one, and systematically discusses and analyzes them. [Display omitted] • A comprehensive review of the latest developments in intelligent wound dressings. • Explored various wound dressing design concepts and developed applications. • Discussed the future prospects and challenges of intelligent wound dressings. Wound management has long been a significant concern within the healthcare industry. However, conventional passive wound dressings often fail to meet the requirements for effective wound management. As a result, there is a growing emergence of intelligent wound dressings that aim to address this issue. These smart wound dressings incorporate one or more electrochemical or optical sensors, enabling real-time monitoring of wound conditions. Furthermore, they also integrate various stimulation techniques, including photostimulation, electrostimulation, and pharmacological stimulation, in order to facilitate accelerated wound healing. This integration of sensing and stimulation capabilities holds immense potential for personalized wound care. This paper offers a comprehensive review of recent advancements in the field of wearable, novel dressings designed for the purpose of chronic wound monitoring and management. It examines various design concepts and applications that have been developed. Additionally, the paper discusses the future prospects and challenges associated with wearable bioelectronics in wound care, as well as their potential for clinical utilization. Furthermore, it explores the areas in which further development and research are needed, with a focus on establishing the priorities for the next generation of wound dressings.

The treatment and care of human wounds represent an enormous burden on the medical system and patients alike. Chronic or delayed healing wounds are characterized by the inability to form proper granulation tissue, followed by deficiencies in keratinocyte migration and wound re-epithelialization, leading to increased likelihood of infection and poor wound outcomes. Human reticular acellular dermal matrix (HR-ADM) is one type of tissue graft developed to enhance closure of delayed healing wounds that has demonstrated clinical utility through accelerating closure of lower extremity diabetic ulcers, but the mechanisms underlying this clinical success are not well understood. The authors utilized a diabetic murine splinted excisional wound model to investigate the effects of HR-ADM application on wound closure. The authors demonstrate that application of HR-ADM served as a dermal scaffold and promoted rapid re-epithelialization and keratinocyte proliferation, resulting in accelerated wound closure while minimizing granulation tissue formation. HR-ADM-applied wounds also demonstrated evidence of cellular infiltration, neovascularization and collagen remodeling by the host organism. These data suggest that HR-ADM supports epidermal closure in delayed healing wounds and remodeling of the matrix into host tissue, lending further support to the clinical success of HR-ADM described in clinical reports.

Abstract: Research to quantify the potency of larval excretion/secretion from Lucilia sericata using liquid culture assays has produced contradictory results. In this study, viable counting was used to investigate the effectiveness of excretion/secretion against three marker bacterial species (Pseudomonas aeruginosa, Staphylococcus aureus, and Escherichia coli) and the effects of varying growing conditions in assays. Results demonstrate that factors such as number of larvae, species of bacteria and addition of nutrient influence its antibacterial potency. Therefore a standardised method should be employed for liquid culture assays when investigating the antibacterial activity of larval excretion/secretion from L. sericata. [ABSTRACT FROM AUTHOR]
