Advances in biomaterials and regenerative medicine for diabetic foot ulcer therapy

Diabetic foot ulcer (DFU), a severe complication of diabetes mellitus, presents significant clinical challenges due to its rapid deterioration and high morbidity rates. While conventional therapies exist kinds of limitations, their clinical utility is frequently constrained. Recent advancements in biomedical engineering have introduced innovative therapeutic modalities, particularly nanomaterials and hydrogels. However, emerging technologies face translational barriers including immature manufacturing processes leading to elevated costs, and insufficient long-term safety data due to limited clinical validation periods. Current clinical studies remain constrained by small cohort sizes and preliminary-stage investigations. The purpose of this study was to review traditional primary treatment and simultaneously combine clinical data to increase the speed of innovative safety, cost, and effectiveness indicator testing.

The emerging role of nanoscaffolds in chronic diabetic wound healing: a new horizon for advanced therapeutics

Non-healing or chronic wounds in extremities that lead to amputations in patients with Type II diabetes (hyperglycemia) are among the most serious and common health problems in the modern world. Over the past decade, more efficient solutions for diabetic ulcers have been developed. Nanofibers and/or composite materials capable of drug delivery, moisture control, and antibacterial effectiveness are increasingly utilized in the formulation of wound dressings, with a particular focus on the biofunctionalization of polymeric and hydrogel materials. Natural products, including plant extracts, honey, antibacterial agents, nanozymes, and metal nanoparticles, are now commonly and effectively implemented to enhance the functionality of wound dressings. Due to the complicated and dysfunctional physiological structure of the chronic wound sites in the extremities of diabetic patients, formulated nanoscaffold or hydrogel components are becoming more intricate and versatile. This study aimed to investigate the development of wound dressing materials over the years while demonstrating their progressively enhanced complexity in effectively targeting, treating, and managing chronic wounds. The mechanisms of action and bio-functionality of wound dressing technologies were elucidated based on findings from 290 studies conducted over the last decade. A notable observation that emerged from these studies is the evolution of wound dressing development technology, which has led to significant advancements in the operational range of smart systems. These include, but are not limited to, self-healing, self-oxygenation, and adaptable mimicry of human tissue.

Surgical sharp debridement alongside maggot debridement therapy (MDT) for the treatment of diabetic foot ulcers (DFUs): A systematic review of case reports

Objective

The objective of this systematic review of case reports is to evaluate the efficacy and safety of combining surgical sharp debridement with maggot debridement therapy (MDT) for the treatment of diabetic foot ulcers (DFUs).

Methods

A comprehensive literature search was conducted across multiple databases, including PubMed, Embase, Cochrane Library, and Web of Science. Inclusion criteria were studies that reported on the use of surgical sharp debridement alongside MDT for DFUs, while exclusion criteria included insufficient detail on treatment methods or patient outcomes, non-human studies, and non-English publications. Data were extracted using a standardized form, and the quality of case reports was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Case Reports. A narrative synthesis was conducted due to the anticipated heterogeneity of the case reports, and a sensitivity analysis was performed to assess the robustness of the findings.

Results

The review process began with 1003 records, which were narrowed down to 721 unique records after removing duplicates. Following title and abstract screening, and full-text assessment, 8 studies were selected for inclusion in the final analysis. The narrative synthesis identified several key findings, including significant wound size reduction, improved glycemic control, disappearance of foul odor, improved healing rates, infection control, granulation tissue formation, epithelialization, complete wound closure, avoidance of amputation, and pain alleviation. The combination therapy showed promise in managing DFUs effectively.

Conclusion

The systematic review of case reports presents evidence supporting the combined use of surgical sharp debridement and maggot debridement therapy in the management of diabetic foot ulcers. The findings suggest that this approach can lead to successful wound healing and limb preservation, offering a valuable addition to the clinician's toolkit for treating DFUs.

A Dioscorea opposita Polysaccharide-Calcium Carbonate Microsphere-Doped Hydrogel for Accelerated Diabetic Wound Healing via Synergistic Glucose-Responsive Hypoglycemic and Anti-Inflammatory Effects

As common complications of diabetes, long-term hyperglycemia and inflammatory infiltration often lead to prolonged unhealing of chronic diabetic wounds. The natural hydrogel-containing plant polysaccharides were recorded to have effective hypoglycemic and anti-inflammatory effects. This study focused on the accelerating effect of diabetic wound healing of hydrogels doped with Dioscorea opposita polysaccharide (DOP)─calcium carbonate (CaCO3) microspheres, which have glucose-responsive insulin release and anti-inflammatory effects. The hydrogel defined as PL-PVA/DOP-CaCO3 was designed via the borate ester bonds between polylysine-phenylboronic acids (PL-PBA) and dihydroxyl groups of poly(vinyl alcohol) (PVA). DOP modified on the surface of CaCO3 microspheres can simultaneously act with PBA to dope into the PL-PVA hydrogel and maintain glucose sensitivity. The mechanical and swelling properties of the hybrid hydrogels were reinforced by the incorporated microspheres. Meanwhile, the hyperglycemia was also regulated by the released insulin and DOP. The in vitro results indicated that the PL-PVA/DOP-CaCO3 hydrogel had good biocompatibility and inflammatory activity and could promote fibroblast proliferation and migration. In vivo experiments demonstrated that the INS@PL-PVA/DOP-CaCO3 hydrogel can significantly promote wound healing in diabetic rats by glucose-responsive regulation of hyperglycemia, inhibiting inflammation, improving angiogenesis, and accelerating the secretion of endothelial cells and proliferation of fibroblasts on wound tissues. The results bring new insights into the field of glucose-responsive hydrogels, showing their potential as drug delivery systems of macromolecular therapeutics to treat diabetic skin wounds.

An Update on Diabetic Foot Ulcer and Its Management Modalities

One of the most prominent challenges related to the management of diabetes is a diabetic foot ulcer (DFU). It has been noted that > 50% of ulcers become clinically infected in diabetic patients, and up to 15-25% of diabetic patients may acquire DFU in their lifetime. DFU treatment is complicated for immune-compromised individuals and has a low success rate. Therefore, diabetic foot care must begin as soon as possible to avoid negative outcomes such as significant social, psychological, and economic consequences, lower limb amputation, morbidity, and mortality. The information provided in this piece is crucial for assisting clinicians and patients regarding novel and cutting-edge treatments for DFU. Due to irrational recourse to antibiotics, etiological agents like bacteria and fungi are exhibiting multidrug resistance (MDR), making topical antibiotic treatments for wounds ineffective with the drugs we currently have. This review article aims to compile the various strategies presently in use for managing and treating DFUs. The piece covers topics like biofilm, diagnosis, drug resistance, multidisciplinary teamwork, debridement, dressings, offloading, negative pressure therapy, topical antibiotics, surgery, cell and gene therapy, and other cutting-edge therapies.

Stem cell therapy with CRISPR/Cas9-mediated MALAT1 delivery modulates miR-142 and rescues wound healing in rats with age-associated diabetic foot ulcers

BACKGROUND

Diabetic foot ulcer (DFU) is a serious diabetes complication, significantly impacting the quality of life, particularly in the elderly. Age-associated DFUs pose additional challenges due to impaired healing mechanisms. Our study aims to explore the role of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) as a miR-142 sponge in repairing diabetic rat foot ulcer tissue under age-associated diabetes, offering a new theoretical basis and therapeutic target for preventing and treating diabetic vascular disease in the elderly.

METHODS

Using qPCR, we analyzed MALAT1 and miR-142 expression in EPCs and hUC-MSCs. Targetscan predicted potential interaction targets for MALAT1 and miR-142, confirmed by dual luciferase reporter gene assay. An age-associated diabetic rat model was established using Streptozotocin (STZ) injection. Hypoxia, apoptosis, and angiogenesis-related proteins were assessed through Western Blot. In vitro, miR-142 inhibition and MALAT1 overexpression promoted foot ulcer healing in diabetic rats.

RESULTS

MALAT1 acted as a miR-142 sponge, downregulated in hUC-MSCs under high glucose, relevant to age-associated diabetic foot ulcers. MiR-142 negatively regulated SIRT1 and Nrf2. In vitro experiments demonstrated potential significance for age-related DFU treatment.

CONCLUSIONS

MALAT1 in human umbilical cord mesenchymal stem cells expedited foot ulcer healing in diabetic rats, particularly in age-associated diabetes, through miR-142 sponge activity. These findings offer insights for novel therapeutic strategies targeting elderly diabetic foot ulcers, emphasizing exogenous stem cell transplantation's potential in effective DFU treatment for the elderly.

The role of medical-grade maggots in facilitating healing of diabetic foot ulcers in Kano, northern Nigeria: a case series

OBJECTIVE

Approximately 13% of people living with diabetes develop one or more ulcers during the course of the disease, and diabetic foot ulcer (DFU) is responsible for >60% of lower limb amputations worldwide. This case series aimed to demonstrate the effectiveness of medical-grade maggots on DFUs in promoting wound healing and reducing related hospital stays in northern Nigeria.

METHOD

Maggot debridement therapy (MDT) was applied to the DFUs of patients who consented to this treatment between January-August 2021 at the Orthopaedic Unit of the Aminu Kano Teaching Hospital (AKTH), Kano, Nigeria. Sterile first instar larvae of Lucilia sericata were obtained indigenously and applied using the confinement (free-range) method under aseptic procedure.

RESULTS

A total of 15 patients with DFUs of Wagner classification grades III (33.3%) and IV (66.7%), were seen and documented. The patients included 10 (66.7%) females and five (33.3%) males, giving a female:male ratio of 2:1. The mean age (±standard deviation) of the respondents was 51.6±10.8 years. The surface area of the wounds ranged from 24-140cm2, with a median value of 75cm2. Among the patients, 60% had two cycles of MDT, with a median duration of five days. Most of the wounds (53.3%) were debrided within five days; 13.3% (two wounds) took seven days to be fully debrided. A paired sample t-test showed a statistically significant association between wound surface area and therapy duration (t=8.0; p=0.000) and between wound surface area and cycles of therapy (t=8.3; p=0.000). Before maggot application, 14 (93.3%) DFUs were completely (100%) covered with slough and only one (6.7%) was 95% covered with slough. After maggot application, 10 (66.7%) wounds were completely debrided while five (33.3%) wounds required bedside surgical debridement to achieve complete debridement. A paired sample t-test showed statistically significant difference between the pre- and post-MDT slough covering the wounds (t=45.1; p=0.000).

CONCLUSION

In this case series, MDT was successfully used in the debridement of DFUs, which facilitated the healing process with an encouraging clinical outcome.

A systematic review of efficacy on larva debridement in diabetic foot ulcers

Larva therapy, also known as maggot therapy, biodebridement, or maggot debridement therapy, involved the application of live fly larva to a patient’s wound for debridement, disinfection, and wound healing. Despite its wide application in diabetic foot ulcers, the efficacy of this intervention remains uncertain. This review aimed to examine the benefits of larva therapy in diabetic foot ulcers by conducting systematic review. This systematic review sought relevant articles using MeSH-based keywords in databases such as Scopus, PubMed, Science Direct, and ProQuest. The inclusion criteria for the articles were as follows: population - patients with diabetic foot ulcers, intervention - the use of debridement or therapeutic application of maggot therapy with Lucilia sericata, comparison - none, outcome - the results of articles demonstrating the effectiveness of using Lucilia sericata maggot therapy on diabetic foot ulcers. Article quality assessment was conducted using the Joanna Briggs Institute guidelines. Descriptive analysis was performed with a narrative approach, considering articles published from 2018 to 2023. Based on the literature search, 237 articles were found with matching keywords from Scopus (103), PubMed (77), Science Direct (14), and ProQuest (43). After screening for inclusion and exclusion criteria, 11 articles were identified for inclusion in this review. These 11 articles indicate that larva therapy can be an effective method in treating diabetic foot ulcers, especially when used correctly and tailored to each patient’s condition and needs. Green bottle fly larva, Lucilia sericata, produce proteolytic enzymes that can assist in wound healing. Larva therapy is effective when combined with other procedures. In clinical practice, it is highly recommended that nurses provide an individualized approach and assess potential side effects.

The effects of coadministration of curcumin and vitamin E on the reproductive system of diabetic male rats; An experimental study

Introduction

Diabetes causes testicular damage due to oxidative stress. Nowadays, the use of vitamins and antioxidants is one of the common methods to treat this disease. Therefore, the aim of this study is to investigate the effect of single and combined administration of these two substances on the reproductive system of male diabetic rats.

Method and materials

In this study, 48 adult male Wistar rats weighing 250-270 grammes were divided into 6 groups: Control group, diabetic group, vehicle group, vitamin E, curcumin group, and vitamin E and curcumin group. The control group was the healthy group, and in the other groups, the rats were made diabetic by streptozotocin (60 mg/kg/ip). The vehicle group received 1 ml of olive oil, the vitamin E group (100 mg/kg/ip) received Vit.E, and the curcumin group (50 mg/kg/ip) received Cu. The group of rats received vitamin E and curcumin. At the end of the sixth week after treatment, blood was taken from the rats and biochemical analysis was performed to check the amount of malondialdehyde (MDA), LH hormones and serum testosterone, then the rats were killed and their testes and epididymides were removed. The weight of the testes and sperm parameters, the maturity of sperm nuclei and the integrity of their DNA were checked. The number of spermatogenic cells was determined by histological examination.

Results

This study showed that diabetes caused a decrease in testicular weight, sperm count, motility, and viability, an increased percentage of sperm with immature nuclei, and an increased percentage of sperm with denatured DNA. In addition, diabetes decreased the average number of matogenic sperm, and biochemical results showed that diabetes increased the level of MDA and decreased the level of the hormones LH and testosterone. Treatment with vitamin E, curcumin and their combination improved all these parameters, and this improvement was significant in the Toam group.

Conclusion

Combined administration of vitamin E and curcumin in diabetic rats significantly improves sperm parameters, matogenic sperm count, and improves MDA levels, LH, and serum testosterone compared with separate treatment.

Current status and progress in research on dressing management for diabetic foot ulcer

Diabetic foot ulcer (DFU) is a major complication of diabetes and is associated with a high risk of lower limb amputation and mortality. During their lifetime, 19%-34% of patients with diabetes can develop DFU. It is estimated that 61% of DFU become infected and 15% of those with DFU require amputation. Furthermore, developing a DFU increases the risk of mortality by 50%-68% at 5 years, higher than some cancers. Current standard management of DFU includes surgical debridement, the use of topical dressings and wound decompression, vascular assessment, and glycemic control. Among these methods, local treatment with dressings builds a protective physical barrier, maintains a moist environment, and drains the exudate from DFU wounds. This review summarizes the development, pathophysiology, and healing mechanisms of DFU. The latest research progress and the main application of dressings in laboratory and clinical stage are also summarized. The dressings discussed in this review include traditional dressings (gauze, oil yarn, traditional Chinese medicine, and others), basic dressings (hydrogel, hydrocolloid, sponge, foam, film agents, and others), bacteriostatic dressings, composite dressings (collagen, nanomaterials, chitosan dressings, and others), bioactive dressings (scaffold dressings with stem cells, decellularized wound matrix, autologous platelet enrichment plasma, and others), and dressings that use modern technology (3D bioprinting, photothermal effects, bioelectric dressings, microneedle dressings, smart bandages, orthopedic prosthetics and regenerative medicine). The dressing management challenges and limitations are also summarized. The purpose of this review is to help readers understand the pathogenesis and healing mechanism of DFU, help physicians select dressings correctly, provide an updated overview of the potential of biomaterials and devices and their application in DFU management, and provide ideas for further exploration and development of dressings. Proper use of dressings can promote DFU healing, reduce the cost of treating DFU, and reduce patient pain.

Evaluating Classification Systems of Diabetic Foot Ulcer Severity: A 12-Year Retrospective Study on Factors Impacting Survival

(1) Background: This study examines the survival of patients after their first presentation with diabetic foot ulcers (DFUs) to the regional Diabetes, Nutrition, and Metabolic Diseases Clinic within the Emergency Clinical Hospital "Sf. Spiridon", Iaşi, and analyzes the factors associated with this outcome. (2) Methods: In this retrospective study, patients with DFUs consecutively referred between 1 January 2007 and 31 December 2017 were followed up until 31 December 2020 (for 13 years). The study group included 659 subjects. (3) Results: During the study period, there were 278 deaths (42.2%) and the average survival time was 9 years. The length of hospitalization, diabetic nephropathy, chronic kidney disease, glomerular filtration rate, cardiovascular disease, hypertension, anemia, and DFU severity were the most significant contributors to the increase in mortality. Patients with severe ulcers, meaning DFUs involving the tendon, joint, or bone, had a higher mortality risk than those with superficial or pre-ulcerative lesions on initial presentation (Texas classification HR = 1.963, 95% CI: 1.063-3.617; Wagner-Meggitt classification HR = 1.889, 95% CI: 1.024-3.417, SINBAD Classification System and Score HR = 2.333, 95% CI: 1.258-4.326) after adjusting for confounding factors. (4) Conclusions: The findings of this study suggested that patients presenting with severe ulcers involving the tendon, joint, or bone exhibited a significantly higher risk of mortality, even when potential confounders were taken into consideration.

Fighting postsurgical infection after myelomeningocele repair with medical honey (Medihoney): a case report

Surgical site infection (SSI) prolongs the treatment period, delays wound healing, increases antibiotic consumption, and leads to patient death in complicated cases. This case was a 10-day female infant born at 37-week- and 6-day of gestational age with a birth weight of 3700 g and Apgar 5/8 by emergency cesarean section due to spina bifida cystica with myelomeningocele (MMC). She was admitted to the neonatal intensive care unit (NICU) because of respiratory distress and hypotonic lower extremities on June 2, 2022. A cardiovascular and neurosurgery consult was okay for reconstructive surgery, and she had MMC repair surgery by a plastic surgeon on June 5, 2022. The surgical site was infected, and SSI had no improvement, despite regularly receiving wet and Vaseline gauze dressing and intravenous antibiotic therapy. We started the treatment using Medihoney™, honey antibacterial wound dressing, on SSI once a day for 2 weeks, then once every other day for the next 6 weeks. Her SSI was cured entirely after 2 months, and she was discharged from our wound treatment team in satisfactory general condition. Clinicians and wound care management teams could use honey antibacterial wound gel to treat SSI, particularly in newborns with weakened immune systems after spinal birth defects repair.

Invasion of undifferentiated pleomorphic sarcoma (UPS) in breast tissue; a case report study

INTRODUCTION AND IMPORTANCE

Breast sarcomas are scarce, histologically heterogeneous with nonepithelial malignancies that originate from the connective tissue within the parenchyma of breast. They can develop primarily, after radio-therapy (RT), or secondary due to chronic condition, including metastatic cancers.

CASE PRESENTATION

The present case report concerns 58-year-old women which was unbeknown to her malignancy in the early stages, until the mass became substantial in size. Chemotherapy and also radiotherapy were not effective, and the growth of tumor could not be prevented which the patient eventually died, due to respiratory complications.

CLINICAL DISCUSSION

Breast sarcomas are categorized in very rare malignancies, and the mortality of these types of cancers are significantly high as they often are not diagnosed in early stages. Based on the location and condition of the malignant tumor, therapeutic methods considered as chemotherapy, radiotherapy, and surgery.

CONCLUSION

In advance stages of breast sarcoma, chemotherapy, radiotherapy, and even surgery cannot be effectual. Therefore, periodical evaluation of breast wellness by diagnostic methods are recommended to all adult women.

H2O2-PLA-(Alg)2Ca Hydrogel Enriched in Matrigel® Promotes Diabetic Wound Healing

Hydrogel-based dressings exhibit suitable features for successful wound healing, including flexibility, high water-vapor permeability and moisture retention, and exudate absorption capacity. Moreover, enriching the hydrogel matrix with additional therapeutic components has the potential to generate synergistic results. Thus, the present study centered on diabetic wound healing using a Matrigel-enriched alginate hydrogel embedded with polylactic acid (PLA) microspheres containing hydrogen peroxide (H2O2). The synthesis and physicochemical characterization of the samples, performed to evidence their compositional and microstructural features, swelling, and oxygen-entrapping capacity, were reported. For investigating the three-fold goal of the designed dressings (i.e., releasing oxygen at the wound site and maintaining a moist environment for faster healing, ensuring the absorption of a significant amount of exudate, and providing biocompatibility), in vivo biological tests on wounds of diabetic mice were approached. Evaluating multiple aspects during the healing process, the obtained composite material proved its efficiency for wound dressing applications by accelerating wound healing and promoting angiogenesis in diabetic skin injuries.

Glucose and MMP-9 dual-responsive hydrogel with temperature sensitive self-adaptive shape and controlled drug release accelerates diabetic wound healing

Chronic diabetic wounds are an important healthcare challenge. High concentration glucose, high level of matrix metalloproteinase-9 (MMP-9), and long-term inflammation constitute the special wound environment of diabetic wounds. Tissue necrosis aggravates the formation of irregular wounds. All the above factors hinder the healing of chronic diabetic wounds. To solve these issues, a glucose and MMP-9 dual-response temperature-sensitive shape self-adaptive hydrogel (CBP/GMs@Cel&INS) was designed and constructed with polyvinyl alcohol (PVA) and chitosan grafted with phenylboric acid (CS-BA) by encapsulating insulin (INS) and gelatin microspheres containing celecoxib (GMs@Cel). Temperature-sensitive self-adaptive CBP/GMs@Cel&INS provides a new way to balance the fluid-like mobility (self-adapt to deep wounds quickly, approximately 37 °C) and solid-like elasticity (protect wounds against external forces, approximately 25 °C) of self-adaptive hydrogels, while simultaneously releasing insulin and celecoxib on-demand in the environment of high-level glucose and MMP-9. Moreover, CBP/GMs@Cel&INS exhibits remodeling and self-healing properties, enhanced adhesion strength (39.65 ± 6.58 kPa), down-regulates MMP-9, and promotes cell proliferation, migration, and glucose consumption. In diabetic full-thickness skin defect models, CBP/GMs@Cel&INS significantly alleviates inflammation and regulates the local high-level glucose and MMP-9 in the wounds, and promotes wound healing effectively through the synergistic effect of temperature-sensitive shape-adaptive character and the dual-responsive system.

•

The hydrogel with temperature-sensitive adaptive shape can fill irregular wounds.

•

The hydrogel on-demand releases drugs responding to diabetic wound environment.

•

The hydrogel significantly accelerated diabetic wound healing.

Surgical debridement and Maggot Debridement Therapy (MDT) can manage diabetic foot ulcers.

An Overview of Diabetic Foot Ulcers and Associated Problems with Special Emphasis on Treatments with Antimicrobials

One of the most significant challenges of diabetes health care is diabetic foot ulcers (DFU). DFUs are more challenging to cure, and this is particularly true for people who already have a compromised immune system. Pathogenic bacteria and fungi are becoming more resistant to antibiotics, so they may be unable to fight microbial infections at the wound site with the antibiotics we have now. This article discusses the dressings, topical antibacterial treatment, medications and debridement techniques used for DFU and provides a deep discussion of DFU and its associated problems. English-language publications on DFU were gathered from many different databases, such as Scopus, Web of Science, Science Direct, Springer Nature, and Google Scholar. For the treatment of DFU, a multidisciplinary approach involving the use of diagnostic equipment, skills, and experience is required. Preventing amputations starts with patient education and the implementation of new categorization systems. The microbiota involved in DFU can be better understood using novel diagnostic techniques, such as the 16S-ribosomal DNA sequence in bacteria. This could be achieved by using new biological and molecular treatments that have been shown to help prevent infections, to control local inflammation, and to improve the healing process.

A review of current advancements for wound healing: Biomaterial applications and medical devices

Wound healing is a complex process that is critical in restoring the skin's barrier function. This process can be interrupted by numerous diseases resulting in chronic wounds that represent a major medical burden. Such wounds fail to follow the stages of healing and are often complicated by a pro‐inflammatory milieu attributed to increased proteinases, hypoxia, and bacterial accumulation. The comprehensive treatment of chronic wounds is still regarded as a significant unmet medical need due to the complex symptoms caused by the metabolic disorder of the wound microenvironment. As a result, several advanced medical devices, such as wound dressings, wearable wound monitors, negative pressure wound therapy devices, and surgical sutures, have been developed to correct the chronic wound environment and achieve skin tissue regeneration. Most medical devices encompass a wide range of products containing natural (e.g., chitosan, keratin, casein, collagen, hyaluronic acid, alginate, and silk fibroin) and synthetic (e.g., polyvinyl alcohol, polyethylene glycol, poly[lactic‐co‐glycolic acid], polycaprolactone, polylactic acid) polymers, as well as bioactive molecules (e.g., chemical drugs, silver, growth factors, stem cells, and plant compounds). This review addresses these medical devices with a focus on biomaterials and applications, aiming to deliver a critical theoretical reference for further research on chronic wound healing.

Targeting Nrf2-Mediated Oxidative Stress Response in Traumatic Brain Injury: Therapeutic Perspectives of Phytochemicals

Traumatic brain injury (TBI), known as mechanical damage to the brain, impairs the normal function of the brain seriously. Its clinical symptoms manifest as behavioral impairment, cognitive decline, communication difficulties, etc. The pathophysiological mechanisms of TBI are complex and involve inflammatory response, oxidative stress, mitochondrial dysfunction, blood-brain barrier (BBB) disruption, and so on. Among them, oxidative stress, one of the important mechanisms, occurs at the beginning and accompanies the whole process of TBI. Most importantly, excessive oxidative stress causes BBB disruption and brings injury to lipids, proteins, and DNA, leading to the generation of lipid peroxidation, damage of nuclear and mitochondrial DNA, neuronal apoptosis, and neuroinflammatory response. Transcription factor NF-E2 related factor 2 (Nrf2), a basic leucine zipper protein, plays an important role in the regulation of antioxidant proteins, such as oxygenase-1(HO-1), NAD(P)H Quinone Dehydrogenase 1 (NQO1), and glutathione peroxidase (GPx), to protect against oxidative stress, neuroinflammation, and neuronal apoptosis. Recently, emerging evidence indicated the knockout (KO) of Nrf2 aggravates the pathology of TBI, while the treatment of Nrf2 activators inhibits neuronal apoptosis and neuroinflammatory responses via reducing oxidative damage. Phytochemicals from fruits, vegetables, grains, and other medical herbs have been demonstrated to activate the Nrf2 signaling pathway and exert neuroprotective effects in TBI. In this review, we emphasized the contributive role of oxidative stress in the pathology of TBI and the protective mechanism of the Nrf2-mediated oxidative stress response for the treatment of TBI. In addition, we summarized the research advances of phytochemicals, including polyphenols, terpenoids, natural pigments, and otherwise, in the activation of Nrf2 signaling and their potential therapies for TBI. Although there is still limited clinical application evidence for these natural Nrf2 activators, we believe that the combinational use of phytochemicals such as Nrf2 activators with gene and stem cell therapy will be a promising therapeutic strategy for TBI in the future.

Clinical outcome of Maggot Debridement Therapy followed by Negative Pressure Wound Therapy for chronic hand wound with Multi-Drug Resistant Organism infection: Two cases and review of the literature

The advancement in science and research has led to development of medical maggots which feed exclusively on dead tissue. Medical maggots have three important functions namely debridement, disinfection, and stimulation of wound healing. The modern use of medical maggots now goes by the term "Maggot Debridement Therapy" (MDT) for use in wound management. MDT is still used infrequently due to the effectiveness of surgical debridement and antibiotics for treatment of wound infection. Lately, there was emergence of Multi-Drug Resistant Organism (MDRO) likely due to inappropriate antibiotics usage. Maggot secretions have been shown to be effective in inhibiting some MDRO, for example, Methicillin-resistant Staphylococcus aureus, thus making MDT an attractive option for wounds with MDRO. We report two patients with multiple medical comorbidities, diagnosed with serious MDRO Diabetic Hand Infections treated with three cycles of MDT followed by Negative Pressure Wound Therapy.

Coaxial structured drug loaded dressing combined with induced stem cell differentiation for enhanced wound healing

Controllable drug-loaded dressings combined with induced stem cell differentiation have received considerable interest. In this study, a directional core-shell drug-loaded magnetocaloric response PCL/Gelatin-Antibiotics/Fe₃O₄ multifunctional dressing was developed. Due to the magnetothermal heating effect of magnetic nanoparticles and the contraction of elastic electrospun fibers, the fibers release antibiotics as needed to prevent drug-resistant infection. IV collagenase catalyzes the degradation of gelatin by achieving an optimum reaction temperature, the purpose of which is also to reduce the viscosity of liquid gelatin and promote the release of drugs. With the sacrifice of gelatin, the directional structure of scaffold and the internal steric hindrance promoted stem cell differentiation and wound healing. The expression of Vimentin, VEGF, bFGF, TGF-β, and THY1 was confirmed by fluorescence immunostaining and RT-PCR. Western blot was used to detect expression of Vimentin, collagen, CD34, and CD31 in the (5/5, v/v) PCL/gelatin scaffold incubated with mouse wound. Therefore, the functional fibers can significantly accelerate the healing process.

Treating surgical site infection by honey antibacterial wound dressing in a neonate: a case report

Surgical site infection (SSI) increases length of treatment, delays wound healing, increases antibiotic use and causes patient death in severe cases. This case was a boy aged 38 weeks and 4 days with a birthweight of 2100 g, a height of 42 cm and a head circumference of 32 cm. Twelve days after birth, he was admitted to hospital where a surgeon removed a sacrococcygeal teratoma. The surgical site became infected, and the infection failed to improve despite him receiving routine normal saline dressings twice a day and intravenous antibiotic therapy. The authors started treatment using an antibacterial wound dressing containing honey (Medihoney) on the SSI twice a day for a month. The infant's SSI was wholly healed after 3 months, and he was discharged from the wound treatment team in good general condition. This case shows that SSIs can be treated with honey-containing antibacterial wound gel, especially in infants who have weaker immune systems.

Reviving hope by using of maggot debridement therapy in patients with diabetic foot ulcer: A case report study

Introduction and importance

Refractory diabetic foot ulcers (DFUs) do not easily respond to standard therapeutic approaches and the prevention of DFU-related amputation is one of the most important aspects of treatment in patients with DFU.

Case presentation

The present case report is 51-year old male patient with a history of 5-years type 2 diabetes who has had DFU on the first distal phalanx foot of his right foot with size of 2 × 2 cm. The patient was repeatedly hospitalized for receiving DFU treatment, he did not recover using routine wound treatment. The patient was transferred to our wound care team. After ten sessions (one session every 48 h) of maggot debridement therapy (MDT) using sterile Lucilia sericata, the patients' DFU had completely healed.

Clinical discussion

DFUs can change patient's quality of life and lead to infection, amputation, sepsis, and finally death. Thus, efficient therapeutic methods are necessary for management of DFUs.

Conclusion

This case report was revealed that the maggot therapy is an affordable and highly efficacious treatment method to enhance the recuperation of DFUs. Therefore, it is recommended that wound care teams use this approach to speed up the healing process.

•

DFU is one of the most significant complications of diabetes mellitus.

•

Affordable and efficacious treatment is necessary for the management of DFUs.

•

Maggot debridement therapy is effective approach for healing DFUs.
