In chronic wounds, the regeneration process is compromised, which brings complexity to the therapeutic approaches that need to be adopted, while representing an enormous loss in the patients’ quality of life with consequent economical costs. Chronic wounds are highly prone to infection, which can ultimately lead to septicemia and morbidity. Classic therapies are increasing antibiotic resistance, which is becoming a critical problem beyond complex wounds. Therefore, it is essential to study new antimicrobial polymeric systems and compounds that can be effective alternatives to reduce infection, even at lower concentrations. The biological potential of polyphenols allows them to be an efficient alternative to commercial antibiotics, responding to the need to find new options for chronic wound care. Nonetheless, phenolic compounds may have some drawbacks when targeting wound applications, such as low stability and consequent decreased biological performance at the wound site. To overcome these limitations, polymeric-based systems have been developed as carriers of polyphenols for wound healing, improving its stability, controlling the release kinetics, and therefore increasing the performance and effectiveness. This review aims to highlight possible smart and bio-based wound dressings, providing an overview of the biological potential of polyphenolic agents as natural antimicrobial agents and strategies to stabilize and deliver them in the treatment of complex wounds. Polymer-based particulate systems are highlighted here due to their impact as carriers to increase polyphenols bioavailability at the wound site in different types of formulations.

Viable Approach

: Chronic wounds remain a significant public problem and the development of wound treatments has been a research focus for the past few decades. Despite advances in the products derived from endogenous substances involved in a wound healing process (e.g. growth factors, stem cells, and extracellular matrix), effective and safe wound therapeutics are still limited. There is an unmet need to develop new therapeutics. Various new pathways and targets have been identified and could become a molecular target in designing novel wound agents. Importantly, many existing drugs that target these newly identified pathways could be repositioned for wound therapy, which will facilitate fast translation of research findings to clinical applications. This review discusses the newly identified pathways/targets and their potential uses in the development of wound therapeutics. Some herbs and amphibian skins have been traditionally used for wound repairs and their active ingredients have been found to act in these new pathways. Hence, screening these natural products for novel wound therapeutics remains a viable approach. The outcomes of wound care using natural wound therapeutics could be improved if we can better understand their cellular and molecular mechanisms and fabricate them in appropriate formulations, such as using novel wound dressings and nano-engineered materials. Therefore, we also provide an update on the advances in the wound therapeutics from natural sources. Overall, this review offers new insights into novel wound therapeutics.

Resistance to antimicrobial agents by pathogenic bacteria has emerged in recent years and is a major health problem. In this context silver and silver nanoparticles (AgNP) have been known to have inhibitory and bactericidal effects and was used throughout history for treatment of skin ulcer, bone fracture, and supporting wound healing. In all of these applications prevention and treatment of bacterial colonized/infected wounds are critical. In this context silver and its derivatives play an important role in health care. Silver is widely used in clinical practice in the form of silver nitrate and/or silver sulfadiazine. In the last few years silver nanoparticles entered into clinical practice as both antimicrobial and antifungal agents. In addition, nanosilver is used in coating medical devices (catheters) and as component of wound dressings. In this paper we present summarized information about silver and nanoparticles made of silver in the context of their useful properties, especially antibacterial ones, being of a great interest for researchers and clinicians.

Collagen plays a significant role in treating acute and chronic wounds such as cuts, burns, ulcers associated with other illness via enhancing the debridement of infected tissues, angiogenesis and promoting natural growth. There are several types of collagen, which can be obtained from various animal sources such as chicken, bovine, porcine, fish etc. Among that bovine based collagen contributed many shares towards biomedical application. Nowadays using bovine based collagen biomaterials for wound care is in trend to minimize the negative impacts such as infection, pain and other side effects. However, its applicable and effectiveness are not fully revealed. At the same time, clinicians and researchers are exploring and implementing advanced techniques and treatment procedures to reduce the wound healing burden effectively. In this review, we aimed to focus on the fundamental information about types of wound dressings, collagen dressings and the clinical utility of bovine based collagen dressings in providing essential knowledge in advanced wound care management.

Wound Bed Preparation

Preparation of the wound bed is a key step in the use of cell- and tissue-based therapy (CTP). In particular, good pre-application debridement is an essential component of CTP. However, there are many situations in which the wound bed is not adequately debrided, including trauma, burn, and in cases of chronic wounds with significant biofilm. In the setting of inadequate wound bed preparation, the use of a CTP that has either added or intrinsic antimicrobial properties is attractive. Some CTPs include added antimicrobial agents such as PHMB or silver, while others have intrinsic antimicrobial components, such as Omega 3 fatty acids. In addition, some wound-covering dressings are completely synthetic, and therefore simply do not become infected. A full understanding of the basic science and clinical data supporting the use of these therapies is important for the advanced wound care practitioner.

Preliminary Study

Abstract Introduction Silver has long been known for its antimicrobial effects and has been commonly applied topically to burn wounds for years. More recently, wound dressings compounded with silver ions, have been developed to prevent and treat wound infection in both burn and chronic wounds. Methods This preliminary study evaluates the effect of a proprietary silver oxynitrate creams on Pseudomonas aeruginosa (PA) biofilms using a well-established burn wound porcine model model. Swine were used due to their skins similarities to humans and response to wound treatments. Briefly, second degree burn wounds were created and inoculated with PA. Wounds were then covered for 24 hours with a polyurethane dressing to allow for biofilm formation. The polyurethane dressing was removed and wounds were randomly assigned to one of the following treatment groups: 1) silver oxynitrate cream 0%, 2) silver oxynitrate cream 4%, 3) silver oxynitrate cream 7%, 4) silver oxynitrate cream * 10%, 5) silver oxynitrate powder, 6) silver sulfadiazine cream (SSD)~, or 7) untreated control. All treatments groups were covered with a polyurethane dressing to prevent any cross contamination. On days 3 and 7 after wounding wounds were cultured using an established scrub technique. Results Silver oxynitrate powder was the most effective treatment group at reducing PA counts. Silver oxynitrate 10% formulation had a high percentage of bacterial reduction. On day 7, compared to untreated control the silver oxynitrate 4, 7 and 10% treatments showed a 3.45, 4.05, and 4.30 log CFU/ml reduction, respectively. Conclusions These studies suggest that the silver oxynitrate formulations can reduce the bacterial bioburden in vivo against wounds that have PA biofilms. Additional animals are needed to substantiate these findings. Applicability of Research to Practice Gram-negative bacteria such as PA pose a challenge for wound care practitioners and new effective therapies are needed.

Management of wound care mainly depends upon the advancement of innovative and effective wound care product to achieve speedy recovery and minimising scar formation. Wound healing management has been always an interesting field of research till date due to serious need for new wound treatment. Appropriate wound care is a significant challenge because of the complications associated with wounds as well as low permeability through the skin. The interconnected events of wound healing occur simultaneously to restore the tissue integrity and functions of the cells. Wound healing gets hampered by numerous factors. These physiological events occur easily in normal human being, but in some situations these molecular events are affected, resulting in hard to heal/ chronic wounds. In current years nanotechnology has emerged as an exciting field with several applications in skin regeneration. These nanoscale delivery systems have numerous benefits in the healing process such as decrease in drug’s cytotoxicity, administration of poorly water-soluble drugs, better skin permeation, controlled release behaviour, antimicrobial activity, as well as stimulation of fibroblast proliferation and reduced inflammation. Thus, emerged as an effective strategy and approach for the treatment of chronic wounds. This review briefly discusses about the wounds, characteristics of an ideal wound dressings along with a special mention regarding the several strategies of wound healing by nanotechnology with their functions and advantages.
