Giving a glance to the report of Wound Care Market by Product updated in 2017, we can see that wound care market is expected to reach USD 22.01 billion by 2022 from USD 18.35 billion at a CAGR of 3.7%. Numerous factors are driving the growth of this market, including the increasing prevalence of chronic wounds and acute wounds, increasing aged population, rising R&D activities and advancement in the field of wound care research. Advanced wound management products are accounted for the largest market share in 2017. These evidences mean that the wound care research represents a Clinical Emergency other than an interesting Marketing tool. Drug therapies so far fight efficaciously with the opportunistic pathologies derived from chronic wounds, although an unsolved challenge is still finding a useful remedy to correct the impaired wound healing process and overcome the chronic wound state, to avoid bacterial rising and severe pain. Traditional medicinal plants have been widely used in the management of wounds and different plant extracts have been evaluated for their wound healing properties through both in vitro and in vivo studies. Their phytochemical components in particular quercetin, contribute to their remedial properties in wound repair. Quercetin has important biological activities related to the improvement of the wound healing process. The present review discusses and focuses on the latest findings of the wound healing properties of quercetin, alone or as a part of plant extract, and its role as a new frontier in wound repair.

Impaired Wound Healing

Impaired wound healing is an encumbering public health issue that increases the demand for developing new therapies in order to minimize health costs and enhance treatment efficacy. Available conventional therapies are still unable to maximize their potential in penetrating the skin at the target site and accelerating the healing process. Nanotechnology exhibits an excellent opportunity to enrich currently available medical treatments, enhance standard care and manage wounds. It is a promising approach, able to address issues such as the permeability and bioavailability of drugs with reduced stability or low water solubility. This paper focuses on nanosized-lipid-based drug delivery systems, describing their numerous applications in managing skin wounds. We also highlight the relationship between the physicochemical characteristics of nanosized, lipid-based drug delivery systems and their impact on the wound-healing process. Different types of nanosized-lipid-based drug delivery systems, such as vesicular systems and lipid nanoparticles, demonstrated better applicability and enhanced skin penetration in wound healing therapy compared with conventional treatments. Moreover, an improved chemically and physically stable drug delivery system, with increased drug loading capacity and enhanced bioavailability, has been shown in drugs encapsulated in lipid nanoparticles. Their applications in wound care show potential for overcoming impediments, such as the inadequate bioavailability of active agents with low solubility. Future research in nanosized-lipid-based drug delivery systems will allow the achievement of increased bioavailability and better control of drug release, providing the clinician with more effective therapies for wound care.

Chronic wound is an important national healthcare problem, compounded by the fact that patients with chronic diseases such as diabetes are always vulnerable to develop chronic wounds. Wound care research has two strands: clinical and computational. On the clinical side, research has been focusing on how to effectively treat wounds. This includes measuring wounds, tracking their progression with time, and assessing their health. On the computational side, little has been done to treat a wound as an engineering system that needs to be modeled and analyzed with the ultimate goal of predicting the progress of wound healing and determining the factors that influence wound healing.

Impaired Wound Healing

Skin wound healing is influenced by two kinds of environment i.e., exterior environment that is nearby to wound surface and interior environment that is the environment of the adjacent part under wound surface. Both types of environment play a vital role in wound healing, which may contribute to continuous or impaired wound healing. Although, different previous studies provided wound care solutions, but they focused on single environmental factors either wound moisture level, pH value or healing enzymes. Practically, it is insignificant to consider environmental effect by determination of single factors or two, as both types of environment contain a lot of other factors which must be part of investigation e.g., smoke, air pollution, air humidity, temperature, hydrogen gases etc. Also, previous studies didn’t classify overall healing either as continuous or impaired based on exterior environment effect. In current research work, we proposed an effective wound care solution based on exterior environment monitoring system integrated with Neural Network Model to consider exterior environment effect on wound healing process, either as continuous or impaired. Current research facilitates patients by providing them intelligent wound care solution to monitor and control wound healing at their home.

The Impact

Background Chronic wounds affect an estimated 2.21 per 1000 population. They are a significant source of morbidity and affect individuals physically, psychologically, socially and financially. Person-centered care is one approach to improve patient outcomes in wound care as it values patients' perspectives, beliefs and autonomy and considers the person as a whole within the cultural context in which care is provided. Aim We aimed to review the evidence on the use of person-centered care (PCC) in chronic wound care management and provide recommendations for practice and future research. Method Using a systematic review methodology, we searched six databases for full-text papers from 2009–2019 published in peer-reviewed journals with no limits on language. Results Eighteen articles on studies involving 3149 patients from nine countries were identified. Studies were conducted under three broad intervention categories: healthcare professional education (n=1); patient education (n=14) and telemedicine (n=3). Studies were equally focused on prevention and treatment of chronic wounds. Significant improvements were reported in patient knowledge, pain and self-care behaviours. Only two studies evaluated the impact on wound healing and one study estimated the cost of implementing person-centered care. Conclusions The evidence base to support PCC in wound management is developing and based on our review has shown improved outcomes in areas of pressure ulcer prevention, patient satisfaction, patient knowledge and quality of life, but clinical outcomes such as wound healing were less well explored. Further research with more objective outcome measures are required.

Age Related

Chronic wounds mainly affect elderly individuals and persons with comorbid diseases due to a compromised immune status. An age-related decline in immune function deters proper healing of wounds in an orderly and timely manner. Thus, older adults with 1 or more concomitant illnesses are more likely to experience and suffer from a nonhealing wound, which may drastically decrease their quality of life and financial resources. Novel therapies in wound care management rely heavily on our current knowledge of wound healing physiology. It is well established that normal wound healing occurs sequentially and is strictly regulated by pro-inflammatory cytokines and growth factors. A multitude of commercial products such as growth factors are available; however, their effectiveness in healing chronic wounds has yet to be proven. Recently, investigators have implicated nitric oxide (NO) in the exertion of regulatory forces on various cellular activities of the inflammatory and proliferative phases of wound healing. Gene therapy in animal studies has shown promising results and is furthering our understanding of impaired wound healing. The purpose of this article is to review the literature on NO and its role in wound healing. A discussion of the physiology of normal healing and the pathophysiology of chronic wounds is provided.

Infection Models

: Wound research is an evolving science trying to unfold the complex untold mechanisms behind the wound healing cascade. In particular, interest is growing regarding the role of microorganisms in both acute and chronic wound healing. Microbial burden plays an important role in the persistence of chronic wounds, ultimately resulting in delayed wound healing. It is therefore important for clinicians to understand the evolution of infection science and its various etiologies. Therefore, to understand the role of bacterial biofilm in chronic wound pathogenesis, various in vitro and in vivo models are required to investigate biofilms in wound-like settings. Infection models should be refined comprising an important signet of biofilms. These models are eminent for translational research to obtain data for designing an improved wound care formulation. However, all the existing models possess limitations and do not fit properly in the model frame for developing wound care agents. Among various impediments, one of the major drawbacks of such models is that the wound they possess does not mimic the wound a human develops. Therefore, a novel wound infection model is required which can imitate the human wounds. : This review article mainly discusses various in vitro and in vivo models showing microbial colonization, their advantages and challenges. Apart from these models, there are also present ex vivo wound infection models, but this review mainly focused on various in vitro and in vivo models available for studying wound infection in controlled conditions. This information might be useful in designing an ideal wound infection model for developing an effective wound healing formulation.

Abstract Background Chronic wounds constitute a significant medical and social problem. Chronic wound treatment may be supported by various techniques, such as negative pressure therapy, phototherapy or stem cells therapy, yet most of those supporting therapies need more evidence to be used for standard wound care. Current study covers the use of sonicated Antlerogenic Stem Cells (ASC) extract on chronic wounds. Methods Study was performed on 20 dermatological patients with venous leg ulcers, divided into two groups – treated with and without ASC extract respectively. The area and circumference of the wounds during the follow-up visits were measured on the wound imprint. Dynamics of wound healing was determined and compared between control and study group; statistics includes changes in absolute values (wound area, circumference), as well as relative (percentage of wound decrease, circumference/area ratio) and their change in time. For the purpose of Ki-67 immunohistochemical staining, sections were sampled from the wound edge at distinct check-points during therapy. Results of both groups were compared with Student test or Mann-Whitney test, depending on results distribution. Results Besides Ki-67 expression, all tested wound healing parameters (including relative and absolute wound decrease and changes in circumference/area ratio) were statistically significant more favorable in experimental group. Conclusion ASC extract significantly supported standard chronic wound treatment. Due to small population of study the results should be considered preliminary, yet promising for further research.

Endothelial Growth Factor

Here, we developed a combinatorial delivery platform for chronic wound healing applications. A microfluidic system was utilized to form a series of biopolymer-based microparticles with enhanced affinity to encapsulate and deliver vascular endothelial growth factor (VEGF). Presence of heparin into the structure can significantly increase the encapsulation efficiency up to 95% and lower the release rate of encapsulated VEGF. Our in vitro results demonstrated that sustained release of VEGF from microparticles can promote capillary network formation and sprouting of endothelial cells in 2D and 3D microenvironments. These engineered microparticles can also encapsulate antibiotic-loaded nanoparticles to offer a dual delivery system able to fight bacterial infection while promoting angiogenesis. We believe this highly tunable drug delivery platform can be used alone or in combination with other wound care products to improve the wound healing process and promote tissue regeneration.
