Topical Reconstituted High-Density Lipoproteins Elicit Anti-Inflammatory Effects in Diabetic Wounds.

Objective: Reconstituted high-density lipoproteins (rHDL) improve wound healing in diabetes. We aimed to determine if rHDL elicit anti-inflammatory effects in diabetic wounds, as a mechanism to explain their wound healing benefits. Approach: Diabetes was induced using streptozotocin in C57Bl6/J mice. Two full-thickness wounds were placed on the subflanks of diabetic and nondiabetic (ND) mice. Phosphate-buffered saline (PBS) or rHDL (50 µg/wound/day) were applied topically. Wound closure was assessed daily. Inflammatory gene transcripts were measured by qPCR and proteins by Western blotting and enzyme-linked immunosorbent assay in wounds collected at baseline, 24 h, and 3 days postwounding. Wound macrophages were assessed by flow cytometry 7 days postwounding. The fate of fluorescent 3,3-dioctadecyloxacarbocyanine, perchlorate (DiO)-labeled rHDL was tracked by flow cytometry, fluorescent imaging, and microscopy. Results: In diabetic mice, rHDL increased wound closure rates at days 6 (+288%, p < 0.01) and 7 (+639%, p < 0.0001) postwounding, compared with PBS controls. After 3 days, rHDL-treated diabetic wounds had lower Rela (-65%) and C-C motif chemokine ligand 2 (Ccl2) (-59%) mRNA levels and CCL2 protein (29%) than PBS controls, p < 0.05 for all. Wound macrophage content was higher in diabetic than ND wounds, but rHDL did not change macrophage content or polarity. DiO-rHDL were taken up by key wound cells including fibroblasts, macrophages, keratinocytes and endothelial cells, and retained in wounds for at least 48 h. Innovation: rHDL exerts anti-inflammatory effects in diabetic wounds early postwounding, which may contribute to its wound healing properties. Conclusion: The anti-inflammatory properties of rHDL in diabetic wounds present topical rHDL as a novel treatment option for improving healing in patients with diabetic foot ulcers.

Vanillic acid promotes keratinocyte migration, proliferation, and angiogenesis

Wound healing is a complex, multi-phase process involving the coordinated interaction of various cells and molecules. This study evaluates the effects of vanillic acid (VA) on wound healing using HaCaT cells. The results demonstrate that VA treatment increases the levels of phosphorylated AMPK protein, thereby activating the AMPK pathway. This activation leads to an upregulation of PNCA expression and enhances the proliferation of HaCaT cells. Additionally, VA treatment reduces the expression of Bax and cleaved Caspase-3 while increasing Bcl2 expression, which inhibits apoptosis in HaCaT cells. Furthermore, VA treatment upregulates the expression of MMP-2 and MMP-9, promoting HaCaT cell migration. VA also induces the secretion of FGF, VEGF, and PDGF, which enhances tube formation in HUVECs. In conclusion, VA may have potential therapeutic benefits in wound healing by promoting keratinocyte proliferation, migration, and angiogenesis.

Therapeutic potential of cannabis for surgical wound healing in rats.

This study was conducted to evaluate the wound-healing activities of a Cannabis sativa L. plant extract and cannabidiol on incision wounds. An incision was created and sutured in rats under anaesthesia. Routine wound care procedures were applied for 10 days, followed by histological wound examinations. The cellular bioactivities of the hemp extract and CBD were assessed for MCP-1, EGF, BFGF, IL-8, and COL-1 using ELISA on the rat skin wound healing activity. A one-way ANOVA was used for the data analysis. The EGF values in the plasma were similar in the povidone-iodine, hemp seed oil, and hemp essential oil groups (P > 0.05). However, the EGF levels were lower in the CBD group compared to the other groups (P < 0.001, P < 0.005). The MCP-1 values in the hemp seed oil, hemp essential oil, and CBD were similar (P > 0.05), whereas povidone iodine exhibited lower MCP-1 levels compared to the other groups (P < 0.001, P < 0.005). It was determined that the plasma BFGF, IL-8, and COL 1 values of the groups were similar (P > 0.05). To our knowledge, this study is the first to evaluate the effects of CBD, seed oil, and hemp leaf extract on incision wound healing. It demonstrates that hemp extract holds greater potential benefits for wound healing compared to CBD.

Accelerated full-thickness skin wound tissue regeneration by self-crosslinked chitosan hydrogel films reinforced by oxidized CNC-AgNPs stabilized Pickering emulsion for quercetin delivery

BackgroundThe non-toxic self-crosslinked hydrogel films designed from biocompatible materials allow for controlled drug release and have gathered remarkable attention from healthcare professionals as wound dressing materials. Thus, in the current study the chitosan (CS) film is infused with oil-in-water Pickering emulsion (PE) loaded with bioactive compound quercetin (Qu) and stabilized by dialdehyde cellulose nanocrystal-silver nanoparticles (DCNC-AgNPs). The DCNC-AgNPs play a dual role in stabilizing PE and are involved in the self-crosslinking with CS films. Also, this film could combine the advantage of the controlled release and synergistic wound-healing effect of Qu and AgNPs.ResultsThe DCNC-AgNPs were synthesized using sodium periodate oxidation of CNC. The DCNC-AgNPs were used to stabilize oil-in-water PE loaded with Qu in its oil phase by high speed homogenization. Stable PEs were prepared by 20% v/v oil: water ratio with maximum encapsulation of Qu in the oil phase. The Qu-loaded PE was then added to CS solution (50% v/v) to prepare self-crosslinked films (CS-PE-Qu). After grafting CS films with PE, the surface and cross-sectional SEM images show an inter-penetrated network within the matrix between DCNC and CS due to the formation of a Schiff base bond between the reactive aldehyde groups of DCNC-AgNPs and amino groups of CS. Further, the addition of glycerol influenced the extensibility, swelling ratio, and drug release of the films. The fabricated CS-PE-Qu films were analyzed for their wound healing and tissue regeneration potential using cell scratch assay and full-thickness excisional skin wound model in mice. The as-fabricated CS-PE-Qu films showed great biocompatibility, increased HaCat cell migration, and promoted collagen synthesis in HDFa cells. In addition, the CS-PE-Qu films exhibited non-hemolysis and improved wound closure rate in mice compared to CS, CS-Qu, and CS-blank PE. The H&E staining of the wounded skin tissue indicated the wounded tissue regeneration in CS-PE-Qu films treated mice.ConclusionResults obtained here confirm the wound healing benefits of CS-PE-Qu films and project them as promising biocompatible material and well suited for full-thickness wound healing in clinical applications.Graphical

An Over-the-Counter Healing Ointment: Benefits in Dry Skin and Wound Healing.

The use of ointments can be beneficial for dry, chapped, or cracked skin and also for supporting wound healing. We describe the results of 2 studies with an over-the-counter healing ointment (HO) to evaluate the effects on skin hydration and in the setting of wound healing after dermatologic procedures.&nbsp; Methods: Study 1 was a single-center, in-use study using HO on qualified areas at least once daily for 4 weeks in subjects with dry, cracked body skin and self-perceived sensitive skin. Study 2 was a multi-center study of wound healing in subjects using HO on a daily basis after having dermatologic surgical procedures.&nbsp; Results: In Study 1, there was a significant reduction in skin dryness after 1 and 4 weeks of HO use (P&lt;0.05). Image analysis of the skin revealed a significant increase in skin smoothness after the first application of HO in 100% of subjects (P&lt;0.05). Tolerability and safety were excellent, and HO was well-perceived by subjects throughout the study. In Study 2, HO improved clinical assessments at all time points compared with baseline with a decrease in erythema, edema, scabbing/crusting, and an improvement in overall wound appearance (P&lt;0.05). There was no worsening or significant increase in measures for tolerability parameters at any study visits. Additionally, HO achieved a favorable perception by study subjects.&nbsp; Conclusions: HO has a well-established safety profile and has been shown to improve both skin hydration and the overall wound healing process after dermatologic surgical procedures.

Protective and Regenerative Effects of Reconstituted HDL on Human Rotator Cuff Fibroblasts under Hypoxia: An In Vitro Study.

Hypoxia and hypo-high-density lipoproteinemia (hypo-HDLemia) are proposed risk factors for rotator cuff tear. HDL is recognized for its potential benefits in ischemia-driven angiogenesis and wound healing. Nevertheless, research on the potential benefits of reconstituted HDL (rHDL) on human rotator cuff fibroblasts (RCFs) under hypoxia is limited. This study investigates the cytoprotective and regenerative effects of rHDL, as well as N-acetylcysteine (NAC), vitamin C (Vit C), and HDL on human RCFs under hypoxic conditions. Sixth-passage human RCFs were divided into normoxia, hypoxia, and hypoxia groups pretreated with antioxidants (NAC, Vit C, rHDL, HDL). Hypoxia was induced by 1000 µM CoCl2. In the hypoxia group compared to the normoxia group, there were significant increases in hypoxia-inducible factor-1α (HIF-1α), heme oxygenase-1 (HO-1), and Bcl-2/E1B-19kDa interacting protein 3 (BNIP3) expressions, along with reduced cell viability, elevated reactive oxygen species (ROS) production, apoptosis rate, expressions of cleaved caspase-3, cleaved poly ADP-ribose polymerase-1 (PARP-1), vascular endothelial growth factors (VEGF), and matrix metalloproteinase-2 (MMP-2), as well as decreased collagen I and III production, and markedly lower cell proliferative activity (p ≤ 0.039). These responses were significantly mitigated by pretreatment with rHDL (p ≤ 0.046). This study suggests that rHDL can enhance cell proliferation and collagen I and III production while reducing apoptosis in human RCFs under hypoxic conditions.

Antimicrobial photodynamic therapy for dermatological infections: current insights and future prospects

Introduction:Light-based antimicrobial photodynamic therapy (aPDT) shows promise against a wide range of microorganisms, including drug-resistant strains, with low resistance development likelihood. However, its limitations include the need for light exposure, suitability for local infections, and limited industry interest. Relevant studies on aPDT for various infections are discussed.Methods:We conducted an extensive literature review on aPDT encompassing articles published from the year 2000 to the current date. To compile comprehensive data, multiple databases (PubMed, Web of Science, Scopus, and Cochrane Library) were systematically searched for relevant studies in both English and Spanish languages. The search strategy involved a combination of Medical Subject Headings (MeSH) terms and free-text terms. The terms included variations and combinations of “Antimicrobial Photodynamic Therapy,” “aPDT,” “photodynamic inactivation,” “microbial photoinactivation,” among others. To ensure the reliability and quality of the information gathered, articles were screened based on relevance to aPDT in antimicrobial therapy, methodological rigor, and alignment with the objectives of this review.Results:aPDT shows promise in treating various cutaneous infections. It effectively targets fungal infections, including caused by dermatophytes and Malassezia spp., with notable results against dermatophytosis and tinea capitis. New photosensitizers, like nanoencapsulated hypericin, hold potential for treating these infections. In onychomycosis, aminolevulinic acid-aPDT or methylene blue-aPDT offers an alternative to conventional therapies, showing cure rates as high as 90%. For bacterial infections, it presents a solution against antibiotic-resistant strains and infected ulcers, with potential benefits for wound healing. Regarding viral infections, it indirectly targets viruses by impacting host cells’ metabolism, showing efficacy against human papillomavirus and herpes viruses. Lastly, aPDT demonstrates success in treating parasitic infections, particularly leishmaniasis, with cure rates of up to 100%.Discussion:aPDT is increasingly used in dermatological infections, showing efficacy against various microorganisms and stimulating wound healing. It can combat resistant strains and mixed infections, especially in chronic wounds. Combining photodynamic therapy with antimicrobials is a promising strategy to address antimicrobial resistance, but there are practical limitations. Further research is needed for home-based protocols, portable devices, and adapting photosensitizers, as aPDT holds potential as an alternative treatment for recalcitrant infections and immunosuppressed patients, though challenges remain in application.

Characterizations of Centrifugal Electrospun Polyvinyl Alcohol/Sodium Alginate/Tamanu Oil/Silver Nanoparticles Wound Dressing.

Known for its water solubility, flexibility, strong adhesion, and eco-friendly nature, polyvinyl alcohol (PVA) is widely used in various industries. In the medical field, it is used for applications such as creating bandages and orthopaedic devices. Incorporating sodium alginate (SA) into PVA membranes enhances their structural integrity, breathability, and permeability, thereby minimising the risk of cellular damage in the wound zone. Moreover, the addition of tamanu oil (C alophyllum inophyllum L.) and silver nanoparticles, both of which are known for their antibacterial properties and benefits in traditional wound healing, further enhances the membranes' wound-healing effectiveness. Following production, the membranes undergo a series of tests designed to evaluate their physical properties as well as their antioxidant and antibacterial capabilities. Subsequently, in vitro testing is conducted using human skin cells; experiments on Wistar rats are then performed. Numerous experiments have consistently demonstrated that the performance of polyvinyl alcohol/sodium alginate/tamanu oil (PVA/SA/Oil) membrane is superior to that of polyvinyl alcohol/sodium alginate/tamanu oil/silver nanoparticles (PVA/SA/Oil/Ag NP) membrane. Specifically, the polyvinyl alcohol/sodium alginate (PVA/SA) combination exhibits an impressive wound-healing rate of 98.82% after 15 days, with cells maintaining a high viability of 92% in a nourishing environment. Moreover, these membranes exhibit exceptional resistance to the oxidation of free radicals, surpassing the 70% threshold, and they possess antibacterial activity against Staphylococcus aureus subsp. aureus in vitro. Based on the obtained results, the nanofiber membranes composed of polyvinyl alcohol/ alginate/ tamanu oil, with or without silver nanoparticles, have shown potential as wound dressings in the wound care discipline.

Functionalization of cotton nonwoven with cyclodextrin/lawsone inclusion complex nanofibrous coating for antibacterial wound dressing

Functionalizing cotton to induce biological activity is a viable approach for developing wound dressing. This study explores the development of cotton-based wound dressing through coating with biologically active nanofibers. Bioactive compounds like lawsone offer dual benefits of wound healing and infection prevention, however, their limited solubility and viability hinder their applications. To address this, Hydroxypropyl-beta-cyclodextrin (HP-β-CD) and Hydroxypropyl-gamma-cyclodextrin (HP-γ-CD) were employed. Inclusion complexations of CD/lawsone were achieved at 2:1 and 4:1 M ratios, followed by the fabrication of CD/lawsone nanofibrous systems via electrospinning. Phase solubility studies indicated a twofold increase in lawsone water-solubility with HP-β-CD. Electrospinning yielded smooth and uniform nanofibers with an average diameter of ∼300–700 nm. The results showed that while specific crystalline peaks of lawsone are apparent in the samples with a 2:1 M ratio, they disappeared in 4:1, indicating complete complexation. The nanofibers exhibited ∼100 % loading efficiency of lawsone and its rapid release upon dissolution. Notably, antibacterial assays demonstrated the complete elimination of Escherichia coli and Staphylococcus aureus colonies. The CD/lawsone nanofibers also showed suitable antioxidant activity ranging from 50 % to 70 %. This integrated approach effectively enhances lawsone's solubility through CD complexation and offers promise for bilayer cotton-based wound dressings.

A Multicenter Retrospective Study Comparing a Polylactic Acid CAMP With Intact Fish Skin Graft or a Collagen Dressing in the Management of Diabetic Foot Ulcers and Venous Leg Ulcers

Background. Venous leg ulcers (VLUs) and diabetic foot ulcers (DFUs) are examples of chronic wounds that pose an ongoing health care challenge. Despite significant progress in managing such wounds, challenges persist that require innovative solutions. Cellular, acellular, and matrix-like products (CAMPs) are advanced therapies designed to facilitate chronic wound healing. Polylactic acid (PLA) is a synthetic material used in alloplastic CAMPs that has shown promise in the management of burns and traumatic injuries. Objective. To retrospectively assess the effect of PLA in promoting chronic wound healing compared with 2 other well-established CAMPs. Materials and Methods. This retrospective chart review, which was conducted in 3 high-volume wound care clinics, aimed to compare the efficacy of 2 advanced wound care products vs a PLA alloplastic CAMP in promoting DFU and VLU closure. The study included 131 wounds treated with a non-CAMP collagen dressing, fish skin grafts (FSGs), or PLA matrices. Inclusion criteria included single Wagner grade 1 or 2 DFUs or Clinical-Etiology-Anatomy-Pathophysiology classification score C6 VLUs, present for at least 12 to 52 weeks, and measuring between 1 cm² and 20 cm². Patients received weekly treatments with 1 of 3 CAMPs, along with standard care. The primary outcome was time to achieve full healing, and the secondary outcome was the proportion of ulcers healed at 12 weeks. Results. The PLA alloplastic CAMP demonstrated superior outcomes, with a 50% and 20% reduction in time to heal DFUs compared with collagen dressings and FSG, respectively (P &lt; .001). For VLUs, PLA exhibited even more impressive results, achieving 95% and 40% reduction compared with collagen and FSG, respectively (P &lt; .001). PLA allografts displayed a 55% higher rate of full healing by 12 weeks compared with collagen dressings, and a 26% higher rate compared with FSG (P &lt; .001). Conclusion. This study highlights the unique attributes of PLA for achieving wound closure. PLA-based alloplastic CAMPs are promising treatments, offering rapid healing, increased closure rates, and multifaceted benefits for wound healing.

Key outcomes gauged encompassed wound closure rate, size reduction, and other related parameters. While most studies showcased PRP's effectiveness, particularly in dressing form, there was a noticeable heterogeneity among the results. In a side exploration, PRP dressing was juxtaposed against PRP injection, revealing both methods' merits in wound management. In conclusion, while PRP treatments, be it in dressing or injectable form, offer potential benefits for chronic wound healing, the variability in study outcomes highlights the need for more standardized research methodologies.

Honey therapies for dermatological disorders: more than just a sweet elixir.

Honey possesses antibacterial, anti-inflammatory, and healing properties that benefit wound healing and tissue regeneration. For centuries, honey has been utilized in traditional medicine as a binder or vehicle for creams and lotions and also for therapeutic purposes. The overuse of antibiotics and antimicrobial agents leading to drug resistance has emphasized the resurgence of honey's application in wound care. For many dermatological disorders, there is an interest in developing therapeutics with fewer side effects than traditional therapies and enhanced wound healing abilities to expedite tissue regeneration. This paper reviews the properties and components of honey that contribute to its wound-healing-based applications, the types of honey employed in medicine, and its dermatological applications. Based on the evidence from case reports, clinical trials, and invitro studies, honey has been characterized as a safe, cost-effective, and readily available treatment option for many skin conditions, including microbial infections, atopic dermatitis, psoriasis, necrotizing fasciitis, ulcers, as well as thermal and other types of wounds.

Acne Scar Management: Minoxidil as a Promising Approach or a Mirage?

Atrophic and hypertrophic scars can result from various conditions, such as acne, trauma, and surgery. Minoxidil, a medication used for the treatment of severe hypertension and hair loss, has been explored as a potential treatment for scars. This review aims to evaluate the current evidence regarding the role of minoxidil in the treatment of scars. Previously published reviews have primarily focused on the use of minoxidil in hair loss and have only briefly mentioned its potential use for scars. However, minoxidil may have a beneficial effect as an antifibrotic agent. Several studies have reported reduced collagen accumulation and fibrosis after treatment with minoxidil. The proposed mechanism of action is inhibition of the production of lysyl hydroxylases (LHs), which modify and cross-link proteins by converting lysine to hydroxylysine, making collagen more resistant to degradation. Minoxidil, as an LH inhibitor, has been shown to potentially benefit wound healing and regeneration in vitro by inhibiting the proliferation and migration of fibroblasts. To date, direct studies of the efficacy of minoxidil in treating acne scars have not been conducted; however, its inhibitory effects on fibroblast function and antifibrotic outcomes in some in vivo studies suggest that such use may be considered.

How I do it: Pedal access and pedal loop revascularization for patients with chronic limb-threatening ischemia.

An increasing proportion of patients with chronic limb-threatening ischemia are older and have multiple comorbidities, including diabetes and renal failure. For those who are not candidates for a surgical bypass, this set of patients presents a challenge to vascular surgeons and interventionalists owing to the complex below-the-knee and increasingly below-the-ankle disease pattern that can fail traditional approaches for endovascular intervention. Two techniques, the retrograde pedal access and the pedal-plantar loop technique, can be useful in these settings and in skilled hands can be used safely, with a high technical success rate. In patients with chronic limb-threatening ischemia who are not candidates for a single-segment saphenous vein bypass, the retrograde pedal access technique can be used not only in the setting of failed antegrade treatment, but also primarily when faced with a difficult groin or as an adjunct during a planned antegrade-retrograde intervention. The pedal plantar loop technique allows for retrograde access to tibial vessels without retrograde vessel puncture and additionally offers the ability to treat the pedal-plantar arch, which may have added benefit in wound healing. We describe the tips and tricks for these two techniques used in our limb salvage practice.

Potential of nanoemulsions for accelerated wound healing: innovative strategies.

Wounds represent various significant health concerns for patients and also contribute major costs to healthcare systems. Wound healing comprises of overlapped and various coordinated steps such as homeostasis, inflammation, proliferation, and remodelling. In response to the failure of many strategies in delivering intended results including wound closure, fluid loss control, and exhibiting properties such as durability, targeted delivery, accelerated action, along with histocompatibility, numerous nanotechnological advances have been introduced. To understand the magnitude of wound therapy, this systematic and updated review discussing the effectiveness of nanoemulsions has been undertaken. This review portrays mechanisms associated with wound healing, factors for delayed wound healing and various technologies utilized to treat wounds effectively. While many strategies are available, nanoemulsions have attracted tremendous attention of scientists globally for the research in wound therapy due to their long-term thermodynamic stability and bioavailability. Nanoemulsions not only aid in tissue repair, but also considered as an excellent delivery system for various synthetic and natural actives. Nanotechnology provides several pivotal benefits in wound healing, including improved skin permeation, controlled release and stimulation of fibroblast cell proliferation. Significant role of nanoemulsions in improved wound healing along with their preparation techniques has also been highlighted with special emphasis on mechanistic insights. This article illustrates recent research advancements for the utilization of nanoemulsions in wound treatment. Adequate literature search has been conducted using keywords "Nanoemulsions in wound healing", "Wound therapy and nanoemulsions", "Herbal actives in wound therapy", Natural oils and wounds treatment" etc. from PubMed, Science Direct and Google Scholar databases. Referred and original publications in the English language accessed till April 2022 has been included, whereas non-English language papers, unpublished data and non-original papers were excluded from the study.
