Hypertrophic scars (HTSs) result from excessive collagen accumulation and impaired wound remodelling, leading to considerable aesthetic and functional concerns. Despite the availability of various treatment strategies, their clinical success remains limited, emphasising the need for alternative approaches. Human amniotic fluid (hAF), naturally enriched with cytokines and growth factors, has emerged as a promising biological material for tissue regeneration. This study investigated the therapeutic potential of two forms of hAF—pooled-frozen and pooled-frozen gamma-irradiated—in a rat model of hypertrophic scarring. Fifteen adult male Sprague–Dawley rats were randomly assigned to receive subcutaneous injections of either saline, pooled-frozen hAF, or pooled-frozen gamma-irradiated hAF at the wound margins on days 1, 3 and 5 following the induction of hypertrophic scars via talc powder application. After 21 days, wound healing was evaluated through histological and immunohistochemical analyses. Both treatment groups demonstrated significantly improved wound healing compared to the control group. Granulation tissue formation was enhanced in the treated groups, particularly in animals receiving gamma-irradiated fluid, which also showed superior collagen remodelling characterised by aligned and mature collagen bundles. Both treatment groups demonstrated an increase in M2 macrophage density, as evidenced by elevated Arg⁺/CD68⁺ cell ratios; however, this effect was more pronounced in the gamma-irradiated group, indicating a stronger shift towards a regenerative immune profile. Enhanced reepithelialisation, increased hair follicle density and reduced scar thickness were also observed. These findings suggest that gamma-irradiated hAF provides a more effective and minimally invasive therapeutic option for modulating scar formation and improving wound healing outcomes, supporting its potential translation into clinical applications for the management of hypertrophic scars.

Surgical site infections (SSI) and surgical site complications (SSC) significantly impact surgery outcomes, increasing hospital stays and mortality rates, and negatively affecting patients' quality of life. Closed-incision negative pressure therapy (ciNPT) emerged as a prophylactic strategy to reduce these complications. However, its applicability across different surgical procedures remains unclear. A scoping review was conducted to synthesise the available evidence on the use of ciNPT in different surgical contexts. A multidisciplinary panel of experts from different surgical specialties was assembled to identify patient risk factors for SSCs specific to each modality. Surgical procedures were categorised based on anticipated SSC rates and the impact of SSI. A decision diagram was finally developed, providing tailored recommendations for ciNPT use according to individual surgical circumstances. The findings of the review indicate that ciNPT effectively reduces SSI and SSC in most surgical procedures. Key patient-related factors influencing outcomes, such as age, obesity, and malnutrition, were outlined. Additionally, a specialty-based list of surgical procedures was compiled, specifying whether ciNPT is recommended, not recommended, or conditionally recommended based on specific criteria. This study underscores the benefits of ciNPT and provides a comprehensive guide to its application across several surgical specialties, aiming to optimise patient management and inform clinical practise.

Soft silicone multi-layer dressings are commonly used for pressure ulcer (pressure injury) prevention, yet their effectiveness varies based on design, construct, and material properties. This study evaluated the protective efficacy of a new multi-layer dressing, ALLEVYN COMPLETE CARE (ACC, Smith & Nephew Limited), which incorporates an advanced structure facilitating the dissipation of shear forces through internal layer-on-layer frictional sliding within the dressing. Using a combination of experimental frictional energy absorber effectiveness (FEAE) testing and computational finite element modelling, we quantified the capacity of this dressing to mitigate strain and stress concentrations in the soft tissues of the supported posterior heel. The dressing demonstrated considerable frictional sliding between its adjacent layers, resulting in FEAE = 93% under simulated, clinically relevant usage conditions. This was associated with the dissipation of shear forces and alleviation of strain/stress concentrations in the skin and underlying soft tissues below the dressing. The dressing completely eliminated the stress and strain peaks at the top quartiles of the strain/stress domain (with reference to a no-dressing case). This work provided valuable insights into advanced testing methods and beneficial design principles for pressure ulcer prevention dressings. Earlier investigations concluded that a previous-generation ALLEVYN LIFE dressing achieved high levels of FEAE and thus provided protection. Our findings here establish that the next-generation dressing, ACC, demonstrates even greater protective capacity.

A novel advanced synthetic bioactive glass matrix was studied in patients with non-healing diabetic foot ulcers (DFUs). Bioactive glasses can be constructed to be biocompatible, with water-soluble materials in multiple geometries including fibre scaffolds that mimic the 3D architecture of a fibrin clot. In this trial, chronic, Wagner Grade 1 DFUs were randomised to receive borate-based bioactive glass Fibre Matrix (BBGFM) plus standard of care (SOC) therapy for 12 weeks or SOC alone. The primary study endpoint was the proportion of subjects that obtained complete wound closure at 12 weeks. Secondary endpoints included time to achieve complete wound closure at 12 weeks. In the modified intent-to-treat (mITT) analysis, 48% (32/67) treated with BBGFM plus SOC healed at 12 weeks compared to 24% (16/66) with SOC alone (p = 0.007). In the per protocol (PP) population, 73% (32/44) of subjects treated with BBGFM plus SOC healed versus 42% (16/38) in the SOC group (p = 0.007). Based on the success of this trial, BBGFM demonstrates faster healing of DFUs compared to SOC and should be considered in the treatment armamentarium for Wagner Grade 1 DFUs. Future trials should investigate the use of BBGFM for healing deeper chronic DFUs, other wound aetiologies, or complex surgical wounds.

Limited evidence exists regarding the effectiveness of learning approaches in supporting interprofessional wound care education transnationally. The aim of this pilot study was to explore the feasibility and preliminary impact of an international, online interprofessional masterclass in supporting baccalaureate health students' learning about wound care. Data were collected using multiple methods including quantitative survey, qualitative focus groups, and interviews with baccalaureate nursing, pharmacy, dietetics, podiatry and paramedicine students from two universities based in Australia and Northern Ireland. A retrospective pre-test design was used. A survey retrospectively assessed students' self-reported confidence and understanding before and after the masterclass, while qualitative methods explored students' experiences of interprofessional learning and wound care. Self-reported improvements in students' understanding of wound assessment and management, as well as heightened awareness of interprofessional contributions to patient care indicated the potential value of this interprofessional and international collaboration in supporting wound care education. Qualitative analysis identified four themes: recognising a wound is a person's wound; comparing international healthcare practices; fostering learner engagement; interprofessional recognition, acknowledgment, and understanding of each profession's roles, contributions and expertise. This pilot study has highlighted key issues to be addressed in future research examining the impact of a collaborative online international initiative on baccalaureate students' interprofessional learning about wound care.

Wound care remains a high-priority area for improvement in the Canadian health care system. Older adults aged 65 and older are disproportionately affected by chronic and non-healing wounds and often experience multiple co-morbid conditions, challenges which can be further complicated by living in rural and northern areas. A workshop-based multi-methods study was conducted to describe rural and northern perspectives on opportunities and feasibility to implement innovative wound care technologies. Each workshop included pre- and post- workshop surveys, a live demonstration of Swift Skin and Wound, a Q&A session, and facilitated discussion exploring the technology's feasibility, usability, and accessibility in northern and rural care contexts. Participants who volunteered for the study included care staff and healthcare executives (N = 11), described their perspectives on implementing AI-driven digital wound care management solutions with a focus on integration into health care settings. Three themes were identified including: confidence and optimism in improving wound care management, recognition of the superiority of AI-driven digital wound care solutions over current practices, and the importance of adaptable change processes for successful adoption. While generalizability may be limited, findings suggest that adopting AI-driven wound care tools could improve wound assessment accuracy and streamline care for aging populations in rural and northern areas.

Chronic wounds pose a public health challenge, with community pharmacists increasingly recognised for their potential role in wound care. Since all chronic wounds originate from acute wounds, pharmacists can play a proactive role in preventing chronicity. Assessing pharmacy staff's wound care knowledge is essential as initiatives to enhance their involvement are underway in Australia. This study aimed to assess wound care knowledge among pharmacists and non-pharmacist staff in Australian community pharmacies. A national cross-sectional electronic survey was conducted between January and August 2022. Developed with multidisciplinary experts, it assessed understanding of wound healing, referral protocols, wound identification, management, and dressing selection. Descriptive and content analyses were performed, and multivariate linear regression identified predictors of knowledge scores. Of 120 responses, 70% were pharmacists, 14% non-pharmacist staff, and 16% unspecified. The median knowledge score was 27 out of 37 (IQR = 21, 30; range = 5–37). Profession, experience, and prior training were significant predictors of higher scores (p < 0.001, R² = 0.347). Dressing knowledge was weakest, with only 10 out of 103 respondents (9.7%) correctly identifying all types and applications. Critical knowledge gaps underscore the need for targeted educational interventions for pharmacy staff.

Animal bites, primarily from dogs and cats, pose a significant threat, especially to children. Wound infections are common complications caused by bacterial flora in the animal's mouth, making surgical debridement and delayed primary closure the standard treatment. However, recent studies reported no increased infection rates with primary closure compared to delayed closure after adequate debridement, particularly for facial wounds. Primary closure offers better cosmetic and functional outcomes. This study presents a case series to guide decision-making on primary suturing versus leaving wounds exposed. Thirty patients with animal bites underwent surgery, including 23 dog bites and seven cat bites. Eight patients with deep facial lacerations from dog bites received immediate debridement and primary closure with epidermal and subcutaneous sutures. None developed infections, and the cosmetic results were excellent. In contrast, all seven cat bite wounds and nine infected dog bite wounds involved high-risk factors, such as puncture wounds, hand injuries or diabetes. For high-risk wounds, early debridement and leaving the wound open after initial treatment proved effective. Primary repair of facial dog bite injuries, even complex ones, is safe and yields good aesthetic outcomes. For high-risk wounds, leaving them open after debridement is recommended to minimise infection risks.

Pressure injuries (PIs) remain a problem for patient safety and the sustainability of healthcare systems. Difficulties persist in their assessment, prevention and monitoring by multidisciplinary teams. International recommendations point to this problem as a priority area for resolution in terms of patient safety. Research on the subject has been positive, resulting in several guidelines for clinical practice, but professionals' adherence remains below what is expected for their implementation. This scoping review aimed to identify interventions that increase multidisciplinary teams' adherence to the prevention and management of PIs between hospitals and the communities. The search was carried out in the MEDLINE (via PubMed), CINAHL, Scopus, Web of Science, JBI, Cochrane and grey literature databases by two independent reviewers, and led to the identification of 16 articles that met the eligibility criteria and made it possible to answer the research question. Strategies to improve adherence by health professionals include the creation and training of multidisciplinary teams, the implementation of new risk assessment models, Wound Boards, injury prevention reminders, video consultation apps, multidisciplinary rounds, documentation and recording. No studies were identified that assessed staff adherence to interventions aimed at preventing and managing PIs in the continuum between hospitals and communities, which is suggestive of the need for further research in this area.
