Impact of Wound Malodour: VOCs and Health-Related Quality of Life



Impact of Wound Malodour: VOCs and Health-Related Quality of Life

Summary: This feasibility study examines how malodour from chronic wounds, driven by volatile organic compounds (VOCs) from bacterial colonization and necrosis, affects patients’ health-related quality of life (HRQoL). Analyzing 92 wounds from 66 patients, it identifies key VOCs like dimethyl disulphide and diacetyl, correlates them with pathogens such as Pseudomonas aeruginosa, and highlights a trend toward greater HRQoL impairment in malodorous cases. The findings advocate for innovative, VOC-targeted therapies to reduce social stigma and support wound healing.

Key Highlights:

  • Malodour stems from bacterial VOCs (e.g., dimethyl disulphide from prokaryotes) and necrosis, with biofilms linked to higher odour perception.
  • Patients with moderate-to-severe odour showed higher HRQoL impairment (Wound-QoL-14 score 2.1 vs. 1.8), correlating with social isolation and delayed care.
  • Pathogen-specific biomarkers identified, such as dimethyl trisulphide for P. aeruginosa and indole for E. coli, enabling targeted antimicrobial strategies.
  • Current dressings like activated charcoal offer partial relief (48% efficacy); future VOC antagonists could enhance biomaterials for odour control and tissue regeneration.
  • Epithializing wounds had lower VOCs and odour, underscoring malodour as a stalled healing marker.

Phytotherapy for Chronic Wound Management in the Era of Antibiotic Resistance

Phytotherapy for Chronic Wound Management in the Era of Antibiotic Resistance

Summary: This literature review explores the potential of plant-derived compounds (phytocompounds) in managing chronic wounds, particularly in the context of rising antimicrobial resistance (AMR) and biofilm-associated infections. Chronic wounds often stall in the inflammatory phase, complicated by polymicrobial biofilms that protect pathogens and resist antibiotics. Phytotherapy offers biocompatible, low-toxicity, and cost-effective alternatives with antimicrobial, antibiofilm, and wound-healing properties. Compounds such as flavonoids, terpenoids, alkaloids, tannic acid, coumarin, resveratrol, berberine, and curcumin show promise in reducing oxidative stress, promoting clotting, stimulating collagen synthesis, and combating infections. Combining natural agents with conventional therapies could enhance outcomes and reduce reliance on resistant antibiotics.

Key Highlights:

  • Background: Chronic wounds are characterized by impaired healing, prolonged inflammation, and frequent biofilm-driven infections. AMR limits the effectiveness of antibiotics, underscoring the need for novel strategies.
  • Mechanisms: Phytocompounds disrupt quorum sensing, suppress virulence factors, reduce oxidative stress, and stimulate angiogenesis and fibroblast activity. They enhance all four healing phases: hemostasis, inflammation, proliferation, and remodeling.
  • Examples:
    • Coumarin: reduces oxidative stress, stabilizes clotting, improves perfusion.
    • Tannic acid: promotes coagulation, wound contraction, and capillary growth.
    • Curcumin: modulates growth factors, reduces oxidative stress, enhances collagen synthesis.
    • Resveratrol: anti-inflammatory, reduces cytokine activity, supports angiogenesis.
    • Berberine: antimicrobial and vascular-stabilizing effects.
  • Clinical potential: Phytocompounds offer synergy with conventional care, biocompatibility, and lower costs. Their antioxidant and antimicrobial effects make them attractive for integration into wound care regimens.
  • Limitations: Evidence remains largely preclinical or early clinical. More controlled trials are required to standardize dosing, delivery, and long-term outcomes.

Mechanism of Action of Astragalus membranaceus for Treating Diabetic Foot Ulcers

Mechanism of Action of Astragalus membranaceus for Treating Diabetic Foot Ulcers Based on Single-Cell RNA Sequencing Data and Network Pharmacology

Summary: Published March 10, 2026 in Scientific Reports (Nature), this open-access study from Kunming University of Science and Technology and affiliated hospitals in Yunnan, China integrates single-cell RNA sequencing (scRNA-seq) and network pharmacology to elucidate the molecular mechanisms by which Astragalus membranaceus (AM, Huangqi) — a widely used traditional Chinese medicinal herb — may modulate the pathological wound microenvironment in diabetic foot ulcers (DFUs). AM has well-documented anti-inflammatory, immunomodulatory, angiogenic, and antioxidant properties across multiple diabetic complications, but its specific mechanisms in DFU had not previously been characterised at single-cell resolution. The study analysed publicly available scRNA-seq data from the Gene Expression Omnibus (accession GSE245703), encompassing 4 non-diabetic foot ulcer (NFU) and 5 DFU samples. UMAP-based dimensionality reduction and CellChat cell-communication analysis identified 10 major cell types within the DFU microenvironment, with macrophage heterogeneity emerging as the dominant pathological feature — consistent with the established role of dysregulated macrophage polarisation (excess M1 pro-inflammatory activity, insufficient M2 repair-promoting transition) in chronic non-healing DFU inflammation. Network pharmacology analysis identified 14 bioactive AM compounds — including quercetin, astragaloside IV, and calycosin — and their computationally predicted molecular targets, a subset of which overlapped significantly with macrophage-associated differentially expressed genes between NFU and DFU samples. Molecular docking analysis confirmed strong calculated binding affinities between selected AM compounds and macrophage hub genes implicated in MMP regulation, BCL-2/apoptosis pathways, and inflammatory cytokine signalling. Clinical qPCR validation in a cohort of 6 NFU and 9 DFU patients confirmed differential expression of several candidate hub genes consistent with computational predictions. The authors present this as a hypothesis-generating, systems-level framework intended to guide future functional and translational studies on AM’s therapeutic potential in DFU.

Key Highlights:

  • Integrative design: scRNA-seq (GSE245703; 4 NFU + 5 DFU) + network pharmacology + molecular docking + clinical qPCR validation (n=15); Yunnan University of Science and Technology, China
  • scRNA-seq: 10 cell types identified in DFU microenvironment; macrophage heterogeneity is dominant — excess M1 polarisation and insufficient M2 transition characterises chronic DFU inflammation
  • 14 bioactive AM compounds identified via SwissADME pharmacokinetic screening, including quercetin, astragaloside IV, and calycosin — each with established anti-inflammatory and immunomodulatory activity
  • Network pharmacology: predicted AM compound targets overlap with macrophage-associated DEGs in DFU vs. NFU — particularly genes regulating MMP activity, apoptosis pathways, and pro-inflammatory cytokine signalling
  • Molecular docking: strong calculated binding affinities between AM bioactive compounds and macrophage hub genes — supports plausibility of the predicted therapeutic interaction
  • qPCR validation (6 NFU, 9 DFU): differential expression of candidate hub genes confirmed in clinical samples; study is explicitly hypothesis-generating — functional in vitro/in vivo validation studies are required before clinical translation

Phytotherapy for Chronic Wound Management in the Era of Antibiotic Resistance



Phytotherapy for Chronic Wound Management in the Era of Antibiotic Resistance

Summary: This literature review examines the potential of phytotherapy—using plant-derived compounds like flavonoids, polyphenols, and alkaloids—as an alternative to antibiotics for managing chronic wounds such as diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs) amid rising antimicrobial resistance (AMR) and biofilm challenges. Drawing from preclinical and early clinical studies, it highlights how phytocompounds disrupt bacterial virulence, reduce oxidative stress and inflammation, and enhance hemostasis, proliferation, and remodeling phases of healing via pathways like TGF-β, NF-κB, and MAPK. Cost-effective and biocompatible, these agents show synergy with antibiotics and promise in topical formulations, though larger RCTs are needed for clinical adoption.

Key Highlights:

  • Key phytocompounds: Curcumin (anti-inflammatory, collagen stimulation), quercetin (biofilm inhibition, M2 macrophage polarization), berberine (DNA disruption, vascular regeneration), resveratrol (COX inhibition, neutrophil reduction), and tannic acid (clotting promotion, free radical scavenging).
  • Mechanisms: Disrupt quorum sensing and EPS in biofilms; modulate cytokines (IL-1, TNF-α), growth factors (VEGF, PDGF), and pathways (AGE-RAGE, IL-17) to counter AMR and oxidative damage in chronic wounds.
  • Evidence: In vitro/animal studies show enhanced closure (e.g., quercetin + gentamicin in diabetic mice); clinical potential in bromelain (NexoBrid for debridement) and curcumin hydrogels; synergy against MRSA in combinatorial therapies.
  • Applications to DFUs/VLUs: Promote granulation, angiogenesis, and ECM synthesis; reduce infection risks in high-burden settings, with nanophytosomes improving delivery.
  • Implications: Affordable adjuncts to standard care; limitations include bioavailability issues and need for standardized trials to integrate into wound protocols.

Development of a Film-Forming Wound Dressing from Periplaneta americana Grease



Development of a Film-Forming Wound Dressing from Periplaneta americana Grease: Formulation, Characterization, and Bioevaluation

Summary: Researchers at Dali University (Yunnan, China) have developed and characterized PAP, a novel film-forming topical wound agent derived from Periplaneta americana grease (PAG) — the lipid-rich fraction of a traditional Chinese medicine source with documented wound-repair properties. PAG was formulated into a PVA-124/PVP-based film-forming system using orthogonal experimental design, producing a transparent, flexible, adherent film that conforms to wound surfaces, maintains a moist environment, and localizes bioactive compounds at the wound site. GC-MS characterization revealed PAG’s complex composition, rich in heterocyclic compounds, terpenoids, sterols, and alkanolamines. In vitro, PAP demonstrated potent free radical scavenging activity comparable to vitamin C and selective antibacterial activity against Staphylococcus aureus. In a murine full-thickness wound model, PAP achieved a 98.2% healing rate by day 10 — comparable to bFGF and the established wound treatment Kangfuxin solution — with vehicle controls confirming that all bioactivity was attributable to the PAG fraction. Histological analysis demonstrated enhanced re-epithelialization, reduced inflammation, and superior collagen organization. Authors note further validation in chronic wound models (diabetic, ischemic) and comprehensive safety assessment are needed before clinical translation.

Key Highlights:

  • 98.2% wound closure rate at day 10, matching bFGF and Kangfuxin liquid positive controls
  • Multifunctional: antioxidant (DPPH/ABTS), antibacterial (S. aureus-selective), and pro-regenerative
  • Vehicle control confirms healing effects are attributable to PAG, not the film matrix
  • Shear-thinning rheology supports easy application; superior mechanical properties vs. vehicle film
  • GC-MS profiling identifies terpenoids, sterols, and heterocyclic compounds as key bioactive classes
  • Relevance: Novel insect-derived biomaterial approach to multifunctional, patient-friendly topical wound management

Pharmacological Advancements of Novel Natural-Based Nanomedicines

Editorial: Pharmacological Advancements of Novel Natural-Based Nanomedicines

Summary: Published March 19, 2026 in Frontiers in Pharmacology (Vol. 17, DOI: 10.3389/fphar.2026.1823081), this editorial by Marios Spanakis (University of Crete, Greece), Ana Isabel Fraguas (Complutense University, Madrid), and Sofia Papadimitriou (Prolepsis Institute, Athens) closes out a Frontiers Research Topic on pharmacological advancements of novel natural-based nanomedicines — an 8-article collection bridging nanoformulation science, translational pharmacology, and regulatory strategy. Natural-based nanomedicines combine biologically derived materials (plant extracts, plant-derived exosome-like nanoparticles, bioactive phytochemicals) with nanotechnology platforms (solid lipid nanoparticles, liposomes, drug-drug nanocrystals, nanoparticle-decorated scaffolds) to overcome the principal limitations of natural compounds in clinical use: poor aqueous solubility, low systemic bioavailability, rapid enzymatic degradation, and limited targeting specificity. The editorial summarises key contributions across metabolic liver disease, wound healing, neurological injury, and oncology. In diabetic wound care — the application most directly relevant to this audience — the collection includes a review by Yadav et al. on nano-enabled delivery systems for plant-derived bioactive formulations in diabetic wound management, discussing how polymeric or metallic nanocarriers can enhance targeted delivery, antimicrobial action, and tissue regeneration, while contextualising emerging nano-therapies within ongoing clinical and patent developments. Other articles cover piperine-loaded solid lipid nanoparticles for non-alcoholic fatty liver disease, ursolic acid drug-drug nanocrystals for cholestatic liver injury (restoring liver function via oxidative stress and bile acid metabolism modulation), and a Rosa canina oligosaccharide liposome for spinal cord injury neuroprotection. In oncology, two articles address green-synthesised silver nanoparticles from plant extracts (biosynthesis review, anticancer profiling) and plant-derived extracellular nanovesicles from Citrus limon showing PI3K/AKT and MAPK/ERK modulation in triple-negative breast cancer models. A bibliometric analysis of plant-derived exosome nanovesicle theranostics rounds out the collection. Cross-cutting themes highlighted by the editors are: (1) nano-encapsulation consistently enhances pharmacokinetics and therapeutic stability of natural compounds; (2) sustainability and biosafety remain essential design considerations; (3) mechanistic understanding linking nanostructure to biological function is increasingly emphasised; and (4) translational progress requires predictive modeling, standardised characterisation, and engagement with regulatory frameworks before preclinical success can translate to clinical practice.

Key Highlights:

  • Diabetic wound relevance: Yadav et al. review covers how nano-enabled delivery of plant-derived bioactives (curcumin, Aloe vera, centella, etc.) can enhance targeted delivery to the wound bed, improve antimicrobial activity, and promote tissue regeneration — linking traditional phytomedicine to modern nanocarrier platforms
  • Formulation science showcase: piperine SLNs enhance oral bioavailability and prolong hepatic circulation; ursolic acid drug-drug nanocrystals with α-tocopherol succinate restore liver function in cholestatic injury — demonstrating how rational nano-design enables synergistic pharmacodynamics not achievable with free compounds
  • Plant-derived nanovesicles: Citrus limon-derived extracellular nanovesicles showed cellular uptake and suppression of proliferation/migration in triple-negative breast cancer models via PI3K/AKT and MAPK/ERK — a field converging green chemistry, nanotechnology, and precision oncology
  • Spinal cord injury application: Rosa canina oligosaccharide liposome improved sensory-motor function, enhanced antioxidant defenses, and promoted neuronal survival in SCI rats — extending natural nanomedicine into neuroprotective contexts
  • Four translational imperatives identified by editors: optimising nano-encapsulation for pharmacokinetic performance; ensuring biosafety and sustainability in green-synthesised materials; advancing mechanistic understanding of nano-bio interactions; and engaging with regulatory frameworks (FDA, EMA) for clinical translation
  • Research Topic scope: 8 articles, 32,000+ views; covers metabolic disorders, oncology, wound healing, neurological injury, and nanovesicle theranostics — reflecting the breadth of natural-based nanomedicine applications now under active investigation

How to apply silver nitrate

Topical application of silver nitrate is often used in wound care to help remove and debride hypergranulation tissue or calloused rolled edges in wounds or ulcerations. It’s also an effective agent to cauterize bleeding in wounds. Silver nitrate is a highly caustic material, so it must be used with caution to prevent damage to healthy tissues.

 

Application method
Silver nitrate applicators are firm wooden sticks with 75% silver nitrate and 25% potassium nitrate embedded on the tip. Moistening the tip sparks a chemical reaction that burns organic matter (skin), coagulates tissue, and destroys bacteria.

Hydrogel Dressings an emerging area for wound care

 

By Liji Thomas, MD

 

An emerging area for wound care is hydrogel dressings as they increase success and speed of wound healing due to the ability to maintain optimum wound healing environment superseding conventional dressings.

 

Hydrogel dressings consist of 90% water suspended in a gel made of insoluble hydrophilic polymers that swell up on contact with water, which are typically synthetic molecule polymers such as polyvinylpyrrolidine and polymethacrylate combined with alginate dressings, that control fluid exchange on wound-bandage interface with sodium and/or other molecules in wound discharge being exchanged for hydrogel compounds.

 

Hydrogel provides moisture to enable painless debridement of infected and necrotic tissues, promoting granulation while encouraging complete healing. Hydrogel dressings have high water content which makes them not completely absorbent and appropriate only for wounds with light to moderate exudation. Skin maceration and/or multiplication of microbes can result from water accumulation which can lead to foul smelling infected wounds. The cooling hydrogels can alleviate some pain, which flatten out the wound surface contours and prevent dead space from getting infected, while providing support for surface healing.

 

Hydrogel sheets are polymeric cross linked molecules capable of absorbing some water helping to prevent wounds with light exudation from becoming to wet with semipermeable polymer film backings. Evaporation is regulated with the backing and keeps wounds from drying out. Sheets can be cut to shape and size, and may be used as secondary or primary dressings … read more

Microvascular complications are responsible for a major proportion of the burden associated with diabetes contributing to substantial morbidity, mortality, and healthcare burden in people with diabetes. Retinopathy, nephropathy, and neuropathy constitute the leading causes of blindness, end-stage renal disease, and lower-extremity amputations, respectively. Since the efficacy of causal therapies of diabetic microvascular complications is limited, especially in type 2 diabetes, there is an unmet need for adjunct treatments which should be effective despite ongoing hyperglycemia. Experimental studies have indicated that diabetic microvascular complications can be prevented or ameliorated by various biofactors in animal models by interfering with the pathophysiology of the underlying condition. Some of the findings related to biofactors, like α-lipoic acid and benfotiamine, could be translated into the clinical arena and confirmed in clinical trials, especially in those focusing on diabetic polyneuropathy. Given the micronutrient nature of these compounds, their safety profile is excellent. Thus, they have the potential to favorably modify the natural history of the underlying complication, but long-term clinical trials are required to confirm this notion. Ultimately, biofactors should expand our therapeutic armamentarium against these common, debilitating, and even life-threatening sequelae of diabetes … read more

Biocomposites to present data on STIMULAN® and genex® at ECCMID 2022

Research findings from two studies demonstrate the antimicrobial effectiveness of STIMULAN® and genex®, when mixed with antibiotics

 

KEELE, England, April 12, 2022 /PRNewswire/ — Biocomposites, an international medical devices company that engineers, manufactures and markets world leading products for use in infection management in bone and soft tissue, today announces the acceptance of two posters at the 32nd European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) being held in Lisbon, Portugal on 23-26 April 2022. The company’s in-vitro research findings demonstrate the antimicrobial effectiveness of both STIMULAN® and genex® when mixed with antibiotics.

 

The first abstract demonstrates that STIMULAN® beads containing vancomycin and gentamicin were able to inhibit bacterial growth, when applied to tissue taken from diabetic foot infections, with zone of inhibition diameters ranging from 12-40mm.

 

The second abstract demonstrates the ability of genex® when mixed with combinations of vancomycin/gentamicin and vancomycin/tobramycin to prevent the formation of bacterial biofilms by MRSA, S. epidermidis and P. aeruginosa for up to 7 days on orthopaedic implant materials.

 

Both studies were co-authored by Julie Fletcher from the University of Exeter whom Biocomposites first funded in 2017 through the Daphne Jackson Trust, the UK’s leading organisation and independent registered charity dedicated to realising the potential of returners to research careers following a career break.

 

Dr Julie Fletcher, Research Fellow, The University of Exeter, said: “This research highlights the potential to use STIMULAN to achieve high local concentrations of antibiotic within poorly vascularised tissue to inhibit bacterial growth at a wound site, with the possibility of facilitating clearance of bacterial infection and improving wound outcomes. The genex research shows the potential to use genex as a carrier of antibiotics to prevent the formation of bacterial biofilm for up to 7 days on orthopaedic implants.”

 

Michael Harris, Chief Executive Officer of Biocomposites, added: “By presenting this new data at this important annual congress, we are pleased to further support the vital research being carried out by leading scientists. STIMULAN and genex are valuable tools for a surgeon and together help over 65,000 patients every year.”

 

STIMULAN® is the only calcium matrix antibiotic carrier approved to treat bacterial infection in surrounding soft tissue in Canada and for use in bone and soft tissue in EU, UK, and Saudi Arabia. STIMULAN® offers surgeons the flexibility to apply broad spectrum ‘off-the-shelf’ antibiotics at concentrations that will support their patient-specific treatment plans – dramatically improving patient outcomes and redefining standard of care.

 

genex is a biphasic composite of exceptional purity that is specifically formulated to balance osteoconductive scaffold strength and persistence in the body to enable the optimal remodelling of bone architecture.

Microbion Corporation Receives up to $2.1 million in Funding Support from the US Navy

in Partnership with CUBRC, Inc. to Advance Topical Pravibismane

 

Funding will support exploratory phase 2 proof-of-concept study in patients hospitalized for moderate to severe diabetic foot ulcer infection (DFI)

 

BOZEMAN, Mont. and VANCOUVER, BC, June 7, 2022 /PRNewswire/ – Microbion Corporation of Bozeman, MT, today announced that it has received non-dilutive funding through its strategic partnership with CUBRC, Inc., a Buffalo-based, independent not-for-profit research company, of up to $2.1 million from the US Navy through the Medical Technology Enterprise Consortium (MTEC) partnership. The funding project is titled “Pravibismane Suspension as a Topical, Broad Spectrum Anti-Infective Wound Care Treatment and Prevention for Combat Injury-Related Infections”. The funding received will be used to support the conduct of an exploratory phase 2 proof of concept trial in patients hospitalized for moderate to severe diabetic foot ulcer infection with enrollment expected to begin in Q2 2022.

 

“We are pleased to be supported by the US Navy and MTEC and are working closely with them to advance our topical pravibismane through phase 2 proof-of-concept studies,” said Karim Lalji, CEO of Microbion Pharma Corp. “Our topical diabetic foot ulcer infection program is well aligned to the Navy’s interest in innovative wound care technologies to treat and prevent biofilm-related infections, since biofilm contamination is a hallmark characteristic of chronic foot ulcer infections. Further exploration of pravibismane’s safety and efficacy in overcoming biofilm-related DFI may potentially expand the clinical utility of topical pravibismane to treat combat wound infections in a variety of settings, including in the field and hospital.”

 

Lester Martinez, MD, MPH, Major General (Retired), U.S. Army, President and Chairman of MTEC Board commented on the importance of Microbion’s research. “Though diabetic foot ulcer infections aren’t traditionally thought of as a combat related wound suffered in the field, diabetes is a serious disease that affects a significantly high percentage of our veterans and its complications such as DFI contributes to decline in health, quality of life and are responsible for the vast majority of non-combat amputations among veterans. Microbion’s research into healing these wounds with the ultimate goal of preventing or delaying amputations can potentially improve the daily lives of these patients and return normal mobility,” Dr. Martinez stated.

 

Pravibismane is the first in a new class of anti-infective drugs structurally unrelated to other clinically utilized antibiotics. With a novel mechanism of action, pravibismane shuts down bacterial ATP production thereby halting global bacterial cellular metabolism. In in vitro studies, pravibismane exhibits broad-spectrum, potent activity against DFI-relevant pathogens and their biofilms including MRSA and drug resistant P. aeruginosa.

 

In a randomized, double-blind, placebo-controlled Phase 1b trial treating patients with chronic moderate to severe diabetic foot ulcer infection, topical pravibismane treatment plus standard of care demonstrated a numeric 85% wound size reduction versus 30% placebo plus standard of care. Pravibismane also demonstrated a numeric reduction in ulcer-related amputation (2.6% in the pravibismane group vs 15.4% placebo).

 

DFIs are a major health concern in the Veterans Health Administration as DFUs are associated with a substantial mortality rate (five-year mortality rates are as high as 45% for neuropathic ulcers and 55% for ischemic ulcers1) and often require amputation to fully address the nidus of infection.2 Approximately 28.5 million adults in the US are diagnosed with diabetes, of whom 15 – 25% are at risk of developing a foot ulcer.3,4 More than half of diabetic foot ulcers become infected.5 DFIs remain the most frequent diabetic complication requiring hospitalization and are the most common precipitating event leading to lower extremity amputation.6 Furthermore, recent studies suggest that many DFIs are caused by bacteria in a biofilm mode.6 In 2018, there were ~8.25 million hospital discharges with diabetes reported, including 154,000 for a lower-extremity amputation.3 US Veterans Affairs estimates there were 20.3 million living Veterans in 2018.7 The overall prevalence of diabetes among US veterans is ~25%, which is higher than the US civilian population at ~9%.8

Title: Broad-Spectrum, Potent Activity of Pravibismane Versus Comparators Against Diabetic Foot Ulcer Infection Patient Isolates Collected in a Phase 1b Study

Presenter: Dr. Jeff Millard, CSO

Poster Highlights:
  • Most common pathogens isolated from DFI subjects (N = 44) at baseline were: methicillin-susceptible Staphylococcus aureus [MSSA (25%)]; methicillin-resistant Staphylococcus aureus [MRSA (18.2%)]; Enterococcus faecalis (13.6%); and Pseudomonas aeruginosa (11.4%).
  • Mean pravibismane minimum inhibitory concentration (MIC) (µg/mL) for S. aureus MSSA was 0.21, S. aureus MRSA was 0.17, E. faecalis was 2.53, and P. aeruginosa was 1.43.
  • Mean pravibismane MICs for 12 of the 13 anaerobic bacteria was ≤1 µg/mL, including against Finegoldia magna and Anaerococcus spp.
  • Pravibismane exhibited similar or lower MIC relative to a panel of comparator antibiotics, including (but not limited to) levofloxacin, linezolid, clindamycin, and piperacillin-tazobactam, against Gram-positive and Gram-negative, susceptible and resistant, aerobes and anaerobes.

"We are pleased that pravibismane demonstrated extremely potent MIC activity against clinical DFI isolates, which was in line with in vitro AST microbial pre-clinical studies," said Dr. Jeff Millard, CSO of Microbion Corp. "Diabetic foot infections are often infected by several different bacterial species concurrently, which may change over the chronicity of the wound, from predominantly aerobic to anaerobic. We believe pravibismane’s potent broad-spectrum activity is potentially a key treatment advantage since a single agent could eradicate both aerobic and anaerobic bacteria, thereby decreasing the need for multiple systemic therapies."

Bacterial cultures for this study were grown from swabs collected at the wound bed at baseline visit and antimicrobial susceptibility testing (AST) was performed on isolated pathogens. Pathogen isolation and AST was performed at Investigational Health Management Associates (IHMA, IL), using the Clinical & Laboratory Standards Institute (CLSI) standard methods.

Topical pravibismane has received QIDP and Fast Track drug designation from the US FDA for the adjunctive treatment of moderate and severe diabetic foot ulcer infections. Topical pravbismane is currently enrolling in a Phase 2 clinical study to further evaluate its safety and efficacy in subjects suffering from moderate infections associated with chronic diabetic foot ulcers.

Research Progress of Multifunctional Hydrogels in Promoting Wound Healing of Diabetes

Advances in Multifunctional Hydrogels for Wound Healing

A comprehensive review published in the *International Journal of Nanomedicine* explores the emerging role of multifunctional hydrogels in wound management—especially for chronic wounds such as diabetic foot ulcers. These hydrogels are designed not just to maintain a moist environment but to actively participate in different stages of the healing process.

Key Insights:

  • Hydrogel Benefits: Hydrogels are biocompatible, water-rich materials that support wound hydration, absorb exudate, reduce pain, and allow for close contact with irregular wound surfaces. They can also serve as delivery vehicles for drugs, growth factors, or cells.
  • Multi-Stage Action: Advanced hydrogels are now being engineered to address specific wound-healing phases—such as controlling bleeding, reducing infection, modulating inflammation, and encouraging angiogenesis and tissue regeneration.
  • Smart Materials: Some hydrogels respond to environmental stimuli like pH, temperature, glucose levels, or oxidative stress. These “smart” systems can release active compounds only when needed, reducing dosing errors and improving treatment outcomes.
  • Antimicrobial & Antioxidant Functions: Silver or copper nanoparticles, along with natural or synthetic antioxidants, are being incorporated into hydrogels to prevent infection and reduce oxidative damage at the wound site.
  • Pro-Angiogenic Design: Hydrogels that deliver VEGF (vascular endothelial growth factor), promote macrophage polarization, or improve blood vessel formation are gaining attention for their regenerative potential.
  • Emerging Technologies: Techniques like 3D bioprinting, microneedle delivery systems, and self-healing injectable hydrogels are pushing the boundaries of design, offering new hope for hard-to-heal wounds.

Challenges: Despite their promise, the clinical translation of multifunctional hydrogels faces hurdles—such as manufacturing complexity, regulatory approval, and ensuring reproducibility and safety across diverse patient populations.

This review emphasizes the transformative potential of hydrogel-based dressings—not only as passive wound covers but as active therapeutic platforms that engage with the biology of wound healing.

Antimicrobial resistance and antimicrobial stewardship: an update

Antimicrobial Resistance & Stewardship: A Wound-Care Update

Published in Volume 33, Issue 2 of Wound Practice & Research (June 2025), this narrative review by Mark G. Rippon, Alan A. Rogers, and Karen Ousey explores the growing global challenge of antimicrobial resistance (AMR) and its implications for wound care. The article underscores the urgency of implementing robust antimicrobial stewardship (AMS) strategies in both acute and chronic wound management.

Key Highlights:

  • Rising Threat of AMR: The misuse and overuse of antibiotics have contributed to rising resistance in wound pathogens, particularly in biofilm-associated infections that are difficult to eradicate.
  • Core Elements of Stewardship: AMS programs emphasize the judicious use of antimicrobials—optimizing drug selection, dosage, treatment duration, and administration route to reduce resistance and improve outcomes.
  • Biofilm Considerations: Biofilms in chronic wounds complicate treatment due to their tolerance to antibiotics and host defenses, reinforcing the need for tailored AMS approaches in wound care settings.
  • Alternative Strategies: The review discusses the role of antimicrobial dressings, bacteriophage therapy, and novel bioengineered compounds as potential tools to reduce reliance on systemic antibiotics.
  • Global AMS Initiatives: Effective stewardship requires a multidisciplinary approach, incorporating surveillance, diagnostic stewardship, prescribing audits, and education at all levels of care.

As wound-related infections continue to evolve, the integration of AMS principles into clinical practice is critical to sustaining effective treatment options and minimizing the spread of resistance.

The Role of Probiotics in Healing Burns and Skin Wounds

The Role of Probiotics in Healing Burns and Skin Wounds: An Integrative Review in Regenerative Medicine

Summary: In an open-access review published in Life (2025, Vol. 15, Issue 9), Lenuta Ambrose, Ciprian Adrian Dinu, Gabriela Gurau, Nicoleta-Maricica Maftei, Madalina Nicoleta Matei, Maria-Andrada Hincu, Marius Radu, and Mihaela-Cezarina Mehedinti examine the evolving evidence supporting use of probiotics and postbiotics in burn care and skin wound healing. The review connects mechanistic insights—anti-inflammatory, immunomodulatory, antimicrobial, regenerative—with translational and pilot clinical outcomes, emphasizing safety, strain selection, and formulation options (topical, systemic) in different wound contexts.

Key Highlights:

  • Probiotics are being investigated not only for gut health but also topically in gels, biofilms, and impregnated dressings, showing promise in reducing bacterial colonization, accelerating re-epithelialization, and promoting angiogenesis.
  • Postbiotics—non-living bioactive compounds produced by probiotic organisms (like peptides, short-chain fatty acids, polysaccharides)—offer similar regenerative benefits with potentially fewer risks.
  • The gut–skin axis is considered: systemic health, microbiota balance, and immune modulation are recognized as contributing to outcomes in burn and wound care.
  • Preclinical models (animal and in vitro) and early clinical studies show positive outcomes, but heterogeneity in strains, dosage, mode of delivery, and timing remain major barriers to standardization.
  • In the context of antimicrobial resistance, probiotics/postbiotics are seen as potential adjunct or alternative therapies, helping reduce dependency on systemic antibiotics.

Research Progress on the Role and Mechanisms of Ferroptosis in Diabetic Wound Repair



Research Progress on the Role and Mechanisms of Ferroptosis in Diabetic Wound Repair

Summary: This review explores ferroptosis—an iron-dependent cell death driven by lipid peroxidation and antioxidant dysregulation—as a key contributor to delayed diabetic wound healing, particularly in diabetic foot ulcers (DFUs). High-glucose environments exacerbate ferroptosis in repair cells (macrophages, fibroblasts, endothelial cells, keratinocytes), disrupting inflammation, angiogenesis, and re-epithelialization. Mechanisms include Fenton reactions from Fe²⁺, PUFA peroxidation via ACSL4/lipoxygenases, and impaired GPX4/GSH defenses. Therapeutic inhibition with Ferrostatin-1, deferoxamine, or natural compounds (resveratrol, PRP, MSC-EVs) reduces ferroptosis, enhancing granulation and closure in diabetic models, while activation targets bacterial biofilms. The review calls for clinical trials on ferroptosis biomarkers and multimodal therapies to overcome DFU chronicity.

Key Highlights:

  • Ferroptosis disrupts diabetic healing via iron overload, ROS, and GPX4 inhibition; key in DFU refractory cases.
  • Cell-specific effects: Macrophages shift to M1; fibroblasts impair ECM; endothelial cells reduce VEGF; keratinocytes delay migration.
  • Inhibitors like Ferrostatin-1 or 4-octyl itaconate accelerate closure 40-60% in diabetic rats by boosting Nrf2/GPX4.
  • Bacterial role: Ferroptosis-sensitive pathogens (E. coli) cleared by iron-loaded hydrogels; aids infection control.
  • Implications: Ferroptosis as DFU biomarker; training for multimodal (topical/systemic) interventions needed.

Mitochondria-mediated inflammation and diabetic wound healing



Mitochondria-mediated inflammation and diabetic wound healing: mechanisms and therapeutic strategies

Summary: This 2026 review by Yao Chen, HuLi Li, and WenJie He systematically examines how mitochondrial dysfunction mediates inflammatory responses and impairs diabetic wound (DW) healing. Hyperglycemia induces excessive ROS production, mtDNA damage, and activation of pathways like NLRP3 inflammasome and cGAS-STING, leading to prolonged inflammation, reduced angiogenesis, and stalled repair. The article details mechanisms linking mitochondrial quality control failure to chronic non-healing ulcers and reviews emerging therapies: mitochondria-targeted antioxidants, nanomaterials, natural compounds, and strategies to restore bioenergetics and reduce oxidative stress. Highlights the need for translational approaches to address this core pathological driver in diabetic foot ulcers and other chronic wounds.

Key Highlights:

  • Mitochondrial ROS and dysfunction central to prolonged inflammation in DFUs
  • Key pathways: NLRP3, cGAS-STING, impaired angiogenesis/collagen deposition
  • Therapeutic targets: Antioxidants, nanomaterials, natural mitochondrial modulators
  • Authors: Yao Chen, HuLi Li, WenJie He

The Crosstalk Between Efferocytosis and Macrophage Polarization in Diabetic Wounds



The Crosstalk Between Efferocytosis and Macrophage Polarization in Diabetic Wounds: A Comprehensive Review

Summary: This comprehensive 2026 review examines how defective efferocytosis (clearance of apoptotic cells) in the diabetic wound microenvironment impairs the transition of macrophages from pro-inflammatory M1 to pro-healing M2 phenotype, leading to persistent inflammation and delayed healing. Hyperglycemia, AGEs, oxidative stress, hypoxia, biofilms, and senescence disrupt efferocytosis receptors (e.g., MerTK) and signaling pathways including JAK/STAT, PI3K/Akt, NLRP3 inflammasome, NF-κB, and MAPK. Failed efferocytosis deprives macrophages of anti-inflammatory signals (TGF-β, IL-10), locking them in M1 dominance. The review discusses therapeutic strategies such as small molecules, natural compounds, and biomaterials (e.g., MerTK nanoparticles, hydrogels) to restore efferocytosis and promote M2 polarization, offering new avenues to overcome limitations in current diabetic wound treatments.

Key Highlights:

  • Impaired efferocytosis blocks M1-to-M2 switch in diabetic wounds
  • Key disrupted pathways: MerTK downregulation, NLRP3 activation, NF-κB sustained signaling
  • Potential therapies target AC clearance and polarization reprogramming
