Abstract
Diabetic wounds are a common complication of diabetes. The prolonged exposure to high glucose and oxidative stress in the wound environment increases the risk of bacterial infection and abnormal angiogenesis, leading to amputation. Microneedle patches have shown promise in promoting the healing of diabetic wounds through transdermal drug delivery. These patches target the four main aspects of diabetic wound treatment: hypoglycemia, antibacterial action, inflammatory regulation, and tissue regeneration. By overcoming the limitations of traditional administration methods, microneedle patches enable targeted therapy for deteriorated tissues. The design of these patches extends beyond the selection of needle tip material and biomacromolecule encapsulated drugs; it can also incorporate near-infrared rays to facilitate cascade reactions and treat diabetic wounds. In this review, we comprehensively summarize the advantages of microneedle patches compared to traditional treatment methods. We focus on the design and mechanism of these patches based on existing experimental articles in the field and discuss the potential for future research on microneedle patches.

Abstract
Background Chronic limb-threatening ischemia (CLTI) is a severe peripheral artery disease with rest pain and lower limb ulceration. After revascularization, limb ulceration treatment should be completed quickly before restenosis. We aimed to investigate the effect of negative pressure wound therapy with instillation and dwell (NPWTi-d) using an antiseptic solution (AS) versus a saline solution (SS) in CLTI. There is no research limited to CLTI on this topic. Methods All patients underwent revascularization and surgical debridement. NPWTi-d was applied after surgical debridement. We evaluated wound tissue cultivation from pre- and post-NPWTi-d, length of NPWTi-d, and laboratory data pre- and post-NPWTi-d. All data are presented as the median, interquartile range. For univariate analysis, nonnormally distributed data were examined using the Wilcoxon rank sum test between the two groups of NPWTi-d (AS and SS group). A P value of less than 0.05 was considered statistically significant. Results Forty-eight CLTI patients participated. The SS group included 24 patients (19 men, five women, average age 68.8 years) and the AS group included 24 patients (16 men, eight women, average age 67.4 years). The comorbidities included 23 and 19 patients with diabetes mellitus and hemodialysis in the SS group, and 22 and 16 patients in the AS group, respectively. There were no adverse events in either group. Both groups reduced the number of bacteria. The AS group required shorter NPWTi-d time (P = 0.02). Conclusion The AS group was able to shorten the treatment duration in CLTI.

Abstract
Introduction Negative Pressure Wound Therapy (NPWT) is a well-established method to promote wound healing by delivering negative pressure (a vacuum) at the wound site. Enhancement of NPWT techniques may allow an innovative way of treating trauma and orthopaedic wounds which provide unique challenges. We explore the role of negative pressure wound therapy with instillation and dwell time (NPWTi-d-) in the management of trauma and orthopaedic wounds. Materials and Methods A comprehensive search strategy was conducted using databases of PubMed, Web of Science, Google Scholar, and Cochrane Library with the search words of 'NPWTid' or 'NPWTi-d-' or 'NPWT with instillation' or 'Negative pressure wound treatment with instillation' to generate this narrative review. The mechanism of action of NPWTi-d-, installation solutions and current applications in the trauma and orthopaedic wounds is evaluated. Results NPWTi-d- provides additional mechanism to promote wound healing in a spectrum of acute and chronic orthopaedic wounds. The technique allows local delivery of hydration and elution of antibiotics to support growth of healthy granulation tissue. Various mechanism of actions contribute in drawing the wound edges together, reduce oedema, help decontamination, deliver local antibiotic and promote healing. Conclusion NPWTi-d- permits an enhanced, supplementary technique to encourage wound healing in challenging traumatic and orthopaedic wounds. Future applications of NPWTi-d- will depend on cost-effectiveness analysis and development of its application guidelines based on longitudinal, randomized controlled research trials.

Abstract
Heel ulcer is one of the severe complications of patients with diabetes mellitus, which poses a high risk for foot infection and amputation, especially in patients with peripheral arterial disease and neuropathy. Researchers have searched for new treatments for treating diabetic foot ulcers in recent years. In this case report, we demonstrated the treatment of large ischemic ulcers for the first time in a diabetic patient. The overall treatment goal of this patient was designed to improve blood supply to her diseased lower extremities and close the ulcer. This two-stage reconstruction approach resulted in an ulcer-free, stable, plantigrade foot at postoperative follow-up.

Abstract
Advanced modalities are used for wounds where conventional treatment is insufficient in diabetic foot patients. In this study, we investigated the effects of using Epidermal growth factor (EGF) and NPWTmodalities alone or in combination on the frequency and level of amputation. In the retrospective study, which included 286 patients in total, 76 patients were referred with the decision of amputation or amputation was planned during hospitalization. After the treatments, amputation and distalization of amputation were found 73.3% and 33.3% in the conventional treatment patients. While 86.4% amp and 18.2% amp distalization were found in negative pressure wound therapy (NPWT) only patients, this rate was 52.4% and 90.5% in EGF + NPWT patients, 50% and 83.3% in EGF only patients. While amp and distalization rates were found to be significantly better in those receiving only EGF or EGF + NPWT (P = .015, P = .017 respectively for amputation and P = .000 for distalization), no difference was found in those receiving EGF and EGF + NPWT. As a result of our study, although npwt contributed positively to the number and level of amputations compared to conventional treatment, a significant improvement was found in the number and level of amps when EGF was used alone or combined with NPWT. With this result, EGF was thought to be an important treatment modality that should be evaluated in diabetic foot ulcers (DFUs) without amputation decision.

Abstract
Weakened wound healing is a popular, severe complication of patients with diabetes which poses a risk for foot infection and amputation. Researchers have searched for new treatments for treating diabetic foot ulcers (DFUs) in recent years. In this case report, for the first time, we applied photobiomodulation therapy (PBMT) and Altrazeal powder together to treat a severe case of DFU in a 47-year-old woman who was suffering from type 1 diabetes. Along with the progress of combination therapy, we observed that the ulcer area was significantly reduced, and the wound healed within 16 weeks. Furthermore, dermatitis and purulent secretion were treated, and the pain was reduced. This reported case study indicated the beneficial effect of the combination of PBMT and Altrazeal powder for the healing of a severe DFU in a patient with type one diabetes. The combined application of PBMT plus Altrazeal powder demonstrated an additive effect. Further clinical trials in the clinical setting are suggested to validate the results further. Besides, more studies in preclinical models are suggested to find the mechanism of the action of combination therapy.

Abstract
OBJECTIVE Mechanical negative pressure wound therapy is an ultraportable, light weight and disposable single-use device that has been shown to promote wound healing. This study evaluated home use of a mechanically powered negative pressure wound therapy (NPWT) in diabetic foot wounds. METHODS Patients underwent revascularisation and/or debridement or amputation before starting mechanical NPWT. Wound outcomes and images of the wounds were recorded at each follow-up visit by the wound nurse. Patients were followed up until wound closure or end of therapy. RESULTS A total of 12 patients (each with one wound) were included in the study. Of the 12 wounds, 33.3% (n=4) of wounds achieved primary wound closure while the remaining 66.6% (n=8) of wounds demonstrated a mean wound size reduction of 37.5±0.13%. Of the closed wounds, mean time to healing was 4.75±2.50 weeks. There was 100% limb salvage with no further debridement or amputations, and no 30-day unplanned readmissions. Mean length of hospital stay before starting home NPWT was 9.75±6.31 days. Mean number of NPWT changes was 8.33±2.67 sessions, while mean duration of therapy was 4.0±1.54 weeks. Mean cost of home NWPT therapy was US$1904±731 per patient. CONCLUSION The home use of mechanically powered NPWT in diabetic foot wounds demonstrated excellent wound healing rates and 100% limb salvage, with no complications.

Abstract
Objective: To analyze long-term outcomes following inpatient treatment of infected wounds with antimicrobial or normal saline instillation during negative pressure wound therapy (NPWT). Approach: This was a single-center retrospective study analyzing the course of patients receiving 0.9% normal saline or 0.1% polyhexanide plus 0.1% betaine as instillation for wounds requiring surgery. Measured outcomes included rates of dehiscence, new wounds, re-operations, amputations, and mortality over 5 years. The article adheres to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement. Results: Forty-two patients received normal saline instillation and 41 the antiseptic solution. Rates of dehiscence, wound recurrence, and re-operations in the saline and antiseptic cohorts were 6.3% and 5.6%, 9.4% and 5.6%, and 14.3% and 9.8%, respectively (p > 0.05). In patients requiring further surgery, time to wound closure averaged 104 and 130 days in the saline and antiseptic cohorts, respectively (p = 0.81). Five-year amputation and mortality rates were 14.3% and 22% (p = 0.36) and 24% and 17% (p = 0.45) in the saline and antiseptic cohorts, respectively. Innovation: To compare clinical outcomes associated with two fundamentally different instillation solutions over the full wound care episode and elucidate the potential impact of these results for future applications. Conclusion: This is the first evaluation of nonsurrogate outcomes of different instillations for NPWT in infected wounds. The results indicate that normal saline instillation outcomes are comparable to those of 0.1% polyhexanide plus 0.1% betaine. The clinical success, cost benefit, and accessibility of normal saline can expand the utilization of this therapeutic approach for larger patient populations.

Abstract
Because China is becoming an aging society, the incidence of diabetes and diabetic foot have been increasing. Diabetic foot has become one of the main health-related killers due to its high disability and mortality rates. Negative pressure wound therapy (NPWT) is one of the most effective techniques for the treatment of diabetic foot wounds and great progress, both in terms of research and its clinical application, has been made in the last 20 years of its development. However, due to the complex pathogenesis and management of diabetic foot, irregular application of NPWT often leads to complications, such as infection, bleeding and necrosis, that seriously affect its treatment outcomes. In 2020, under the leadership of Burns, Trauma and Tissue Repair Committee of the Cross-Straits Medicine Exchange Association, the writing group for ‘Consensus on the application of negative pressure wound therapy of diabetic foot wounds’ was established with the participation of scholars from the specialized areas of burns, endocrinology, vascular surgery, orthopedics and wound repair. Drawing on evidence-based practice suggested by the latest clinical research, this consensus proposes the best clinical practice guidelines for the application and prognostic evaluation of NPWT for diabetic foot. The consensus aims to support the formation of standardized treatment schemes that clinicians can refer to when treating cases of diabetic foot.

Surgical OFF-LOADING of the diabetic foot. J Clin Orthop Trauma 2021; 16:182-188.

Abstract
Diabetic foot ulcer treatment is a challenge for the healthcare world. Widespread infection and the presence of critical ischemia (especially with end-stage renal disease) can lead to major amputation rather than amenable to conservative treatment. Surgical strategies of the diabetic foot have been changing over the past 10 years and are now focused on reconstructive treatment and limb salvage. These goals were achieved, thanks to an evolution of distal revascularization techniques and a distinct approach, which integrates various methods focused on limb salvage. Podoplastic techniques of the diabetic foot are focused on infection clearance, the surgical treatment of corrective deformities, soft tissue coverage and limb ischemia correction along with the management of diabetes and the comorbidities that compromise tissue repair processes. The reconstructive techniques used in diabetic foot treatment owe their effectiveness in part to the results of technological improvements such as the circular external fixator as a tool for stabilization and surgical site protection. In the last decade, many studies have shown that circular external fixation should be considered as the most useful method to protect the reconstructive surgical site in limb salvage of the diabetic foot. The objective of this review is to highlight the role of surgical offloading using circular external fixation as an adjunct to the podoplastic diabetic foot reconstruction procedures.

Abstract
Aim: This work aims to explore the biological role of negative pressure wound therapy (NPWT) in the treatment of diabetic ulcer. Materials & methods: Full-thickness skin defects were created in diabetic (db/db) and non diabetic (db/m) mice to create wound models. The mice were received NPWT or rapamycin injection. Mouse macrophage cells (Raw264.7) were treated with lipopolysaccharide to induce inflammatory response, and then received negative pressure treatment. We observed the wound healing of mice and examined gene and protein expression and CD68+ macrophage levels. Results: NPWT notably enhanced the wound closure ratio, and inhibited the LC3-II/LC3-I ratio and Beclin-1 expression in diabetes mellitus (DM) mice. NPWT decreased CD68+ macrophage levels in wound tissues of DM mice. The influence conferred by NPWT was abolished by rapamycin treatment. Negative pressure repressed the LC3-II/LC3-I ratio and the expression of Beclin-1, TNF-α, IL-6 and IL-1β in the Raw264.7 cells. Conclusion: NPWT promotes wound healing by suppressing autophagy and macrophage inflammation in DM.

Abstract
1. Introduction Since its introduction in clinical practice in the early 1990's negative pressure wounds therapy (NPWT) has become widely used in the management of complex wounds in both inpatient and outpatient care.1 NPWT has been described as a effective treatment for wounds of many different aetiologies2,3 and suggested as a gold standard for treatment of wounds such as open abdominal wounds,4-6 dehisced sternal wounds following cardiac surgery7,8 and as a valuable agent in complex non-healing wounds.9,10 Increasingly, NPWT is being applied in the primary and home-care setting, where it is described as having the potential to improve the efficacy of wound management and help reduce the reliance on hospital-based care.11 While the potential of NPWT is promising and the clinical use of the treatment is widespread, highlevel evidence of its effectiveness and economic benefits remain sparse.12-14 The ongoing controversy regarding high-level evidence in wound care in general is well known. There is a consensus that clinical practice should be evidence-based, which can be difficult to achieve due to confusion about the value of the various approaches to wound management; however, we have to rely on the best available evidence. The need to review wound strategies and treatments in order to reduce the burden of care in an efficient way is urgent. If patients at risk of delayed wound healing are identified earlier and aggressive interventions are taken before the wound deteriorates and complications occur, both patient morbidity and health-care costs can be significantly reduced. There is further a fundamental confusion over the best way to evaluate the effectiveness of interventions in this complex patient population. This is illustrated by reviews of the value of various treatment strategies for non-healing wounds, which have highlighted methodological inconsistencies in primary research. This situation is confounded by differences in the advice given by regulatory and reimbursement bodies in various countries regarding both study design and the ways in which results are interpreted. In response to this confusion, the European Wound Management Association (EWMA) has been publishing a number of interdisciplinary documents15-19 with the intention of highlighting: The nature and extent of the problem for wound management: from the clinical perspective as well as that of care givers and the patients Evidence-based practice as an integration of clinical expertise with the best available clinical evidence from systematic research The nature and extent of the problem for wound management: from the policy maker and healthcare system perspectives The controversy regarding the value of various approaches to wound management and care is illustrated by the case of NPWT, synonymous with topical negative pressure or vacuum therapy and cited as branded VAC (vacuum-assisted closure) therapy. This is a mode of therapy used to encourage wound healing. It is used as a primary treatment of chronic wounds, in complex acute wounds and as an adjunct for temporary closure and wound bed preparation preceding surgical procedures such as skin grafts and flap surgery. Aim An increasing number of papers on the effect of NPWT are being published. However, due to the low evidence level the treatment remains controversial from the policy maker and health-care system's points of view-particularly with regard to evidence-based medicine. In response EWMA has established an interdisciplinary working group to describe the present knowledge with regard to NPWT and provide overview of its implications for organisation of care, documentation, communication, patient safety, and health economic aspects. These goals will be achieved by the following: Present the rational and scientific support for each delivered statement Uncover controversies and issues related to the use of NPWT in wound management Implications of implementing NPWT as a treatment strategy in the health-care system Provide information and offer perspectives of NPWT from the viewpoints of health-care staff, policy makers, politicians, industry, patients and hospital administrators who are indirectly or directly involved in wound management.

Abstract
BACKGROUND Chronic wounds have become an increasing medical and economic problem of aging societies because they are difficult to manage. Skin grafting is an important treatment method for chronic wounds, which are refractory to conservative therapy. The technique involving epidermal cell suspensions was invented to enable the possibility of treating larger wounds with only a small piece of donor skin. Both uncultured and cultured autologous epidermal cell suspensions can be prepared and survive permanently on the wound bed. METHODS A systematic search was conducted of EMBASE, Cochrane Library, PubMed and web of science by using Boolean search terms, from the establishment of the database until May 31, 2014. The bibliographies of all retrieved articles in English were searched. The search terms were: (epithelial cell suspension OR keratinocyte suspension) and chronic and wound. RESULTS From the included, 6 studies are descriptive interventions and discussed the use of autologous keratinocyte suspension to treat 61 patients' chronic wound. The various methods of preparation of epidermal cell suspension are described. The advantages and shortcomings of different carriers for epidermal cell suspensions are also summarised. Both uncultured and cultured autologous epidermal cell suspensions have been used to treat chronic wounds. CONCLUSION Although the limitations of these studies include the small number of patient populations with chronic wounds and many important problems that remain to be solved, autologous epidermal cell suspension is a promising treatment for chronic wounds.

Novel negative pressure wound therapy with instillation and the management of diabetic foot infections. Curr Opin Infect Dis 2015; 28:151-7.

Abstract
PURPOSE OF REVIEW The use of negative pressure wound therapy with instillation (NPWTi) in complex or difficult-to-treat acute and chronic wounds has expanded rapidly since the introduction of commercially available NPWTi systems. We summarize the evidence related to NPWTi and particularly focus on the application of this technology in diabetic foot ulcers, diabetic foot infections and postoperative diabetic wounds. RECENT FINDINGS The benefits of negative pressure wound therapy (NPWT) are well documented in the treatment of complex acute and chronic wounds, including noninfected postoperative diabetic wounds and diabetic foot ulcers. Combining intermittent wound irrigation with NPWT may offer additional benefits compared to NPWT alone, including further reduction of wound bed bioburden, increased granulation tissue formation and provision of wound irrigation in a sealed environment, thus preventing potential cross-contamination events. Recently, available evidence suggests that adjunctive NPWTi may be superior to standard NPWT in the management of diabetic infections following surgical debridement and may promote granulation tissue formation in slow-to-heal wounds. SUMMARY Available evidence relating to the utilization of NPWTi in diabetic foot infections is promising but limited in quality, being derived mostly from case series or small retrospective or prospective studies. In order to confirm or refute the potential benefits of NPWTi in this patient cohort, well designed randomized controlled studies are required that compare NPWTi to NPWT or standard wound care methodologies.

Abstract
Significance: Chronic wounds include, but are not limited, to diabetic foot ulcers, venous leg ulcers, and pressure ulcers. They are a challenge to wound care professionals and consume a great deal of healthcare resources around the globe. This review discusses the pathophysiology of complex chronic wounds and the means and modalities currently available to achieve healing in such patients. Recent Advances: Although often difficult to treat, an understanding of the underlying pathophysiology and specific attention toward managing these perturbations can often lead to successful healing. Critical Issues: Overcoming the factors that contribute to delayed healing are key components of a comprehensive approach to wound care and present the primary challenges to the treatment of chronic wounds. When wounds fail to achieve sufficient healing after 4 weeks of standard care, reassessment of underlying pathology and consideration of the need for advanced therapeutic agents should be undertaken. However, selection of an appropriate therapy is often not evidence based. Future Directions: Basic tenets of care need to be routinely followed, and a systematic evaluation of patients and their wounds will also facilitate appropriate care. Underlying pathologies, which result in the failure of these wounds to heal, differ among various types of chronic wounds. A better understanding of the differences between various types of chronic wounds at the molecular and cellular levels should improve our treatment approaches, leading to better healing rates, and facilitate the development of new more effective therapies. More evidence for the efficacy of current and future advanced wound therapies is required for their appropriate use.

Abstract
Chronic wounds such as diabetic foot wounds are a tremendous burden to the health care system and often require a multidisciplinary approach to prevent amputations. Advanced technologies such as negative pressure wound therapy (NPWT) and bioengineered tissues have been successfully used in the treatment of these types of complex wounds. However, the introduction of NPWT with instillation (NPWTi) has provided an alternative treatment for treating complex and difficult-to-heal wounds. This article provides an overview of NPWT and the new NPWTi system and describes preliminary experience using NPWTi on patients with complicated infected diabetic foot wounds after surgical debridement and in a multidisciplinary setting.
