Abstract
Chronic wounds, especially those that are hard-to-heal, constitute a serious public-health problem. Although progress has been made in the development of wound dressings for healing, there is little high-quality evidence of their efficacy, with no evidence of superiority in the use of one hydrogel over another. To evaluate the superiority of a hydrogel (EHO-85), containing Olea europaea leaf extract (OELE), over a standard hydrogel (SH), the promotion and/or improvement of healing of difficult-to-heal wounds was compared in a prospective, parallel-group multicenter, randomized, observer-blinded, controlled trial ("MACAON"). Non-hospitalized patients with pressure, venous or diabetic foot-ulcers difficult-to-heal were recruited and treated with standard care, and EHO-85 (n = 35) or VariHesive (n = 34) as SH. Wound-area reduction (WAR; percentage) and healing rate (HR; mm2/day) were measured. EHO-85 showed a statistically significant superior effect over VariHesive. At the end of the follow-up period, the relative WAR decreased by 51.6% vs. 18.9% (p < 0.001), with a HR mean of 10.5 ± 5.7 vs. 1.0 ± 7.5 mm2/day (p = 0.036). EHO-85 superiority is probably based on its optimal ability to balance the ulcer bed, by modulating pH and oxidative stress. That complements the wetting and barrier functions, characteristics of conventional hydrogels. These results support the use of EHO-85 dressing, for treatment of hard-to-heal ulcers.

Abstract
Venous leg ulcers and chronic oedema including lymphoedema are lifelong conditions that cause great distress to sufferers due to psychophysical symptoms. Time and resources spent on managing chronic wounds place an economic burden on healthcare providers, particularly with an anticipated increase in an ageing population and diminishing numbers of those providing long-term care. Resources are further challenged if wounds remain unhealed. The human costs are even greater, with patients often facing a lifetime of discomfort due to low awareness of venous disease, despite epidemiological studies. Possible causes of persistent venous disease may be misdiagnosis, mismanagement, or simply, no management if help is not sought. Therefore, it is important that chronic leg ulcers are managed with clinically effective regimes, reassessment, monitoring and appropriate referrals for adjunct management, alongside patient education. This article provides simple timescaled measurements to ensure timely interventions and appropriate care at each stage.

The development of a core outcome set for clinical effectiveness studies of bordered foam dressings in the treatment of complex wounds. J Tissue Viability 2023:S0965-206X(23)00046-3.

Abstract
AIM The aim of this project was to develop a core outcome set (COS) for clinical effectiveness studies of bordered foam dressings in the treatment of complex wounds. METHODS The research project followed the Core Outcome Measures in Effectiveness Trials (COMET) initiative and consisted of two phases. The first phase prepared the background and process, while the second phase had three steps: outcome list generation via systematic review and qualitative study, Delphi consensus study, and consensus meeting. The study has been registered in the Core Outcome Measures in Effectiveness Trials database. RESULTS The systematic review resulted in 82 outcomes and 20 additional outcomes were obtained during the interviews. After refinement, 111 panellists from 23 countries rated a list of 51 outcomes. In the following consensus meeting, six outcomes were prioritized to be included in the core outcome set. After the consensus meeting, a patient-reported outcome was added to the core outcome set. CONCLUSION The COS for evaluating the effectiveness of bordered foam dressings in treating complex wounds includes 7 outcomes: "ability to stay in place", "leakage", "pain", "dressing related periwound skin changes", "change in wound size over time", and "overall satisfaction". These identified outcomes are correlated with contemporary bioengineering testing and evaluation methods for dressing performance, which underpins the need for a close multidisciplinary collaboration to advance the field of wound dressings. The outcome 'overall satisfaction' reflects the impact of complex wounds and their treatment on a patient's daily life. The use of these outcomes is recommended to improve data synthesis and promote evidence-based practice. Future developments in COS development involve creating measurement instruments and relevant endpoints for these outcomes.

Abstract
OBJECTIVE This audit was designed to identify the need of the population and the clinical activity associated with wounds and the management of lower limb swelling. The exploration focused on lower leg wound management, access to diagnostics and compression therapy across each audit site. The variation across the sites was explored to gather insight into the real-world barriers to providing evidence-based management for leg ulceration. METHOD We undertook wound prevalence audits across six diverse community provider sites in England. The audit was undertaken by the local providers, with the inclusion of tissue viability and podiatry leads and key local stakeholders, often local quality leads, primary care leads and nursing directors. Each audit was undertaken with full engagement of local clinicians. Data were collected centrally, and each audit site received their own local analysis and report, with additional analytical support from the local tissue viability lead to ensure the feedback was contextualised for their stakeholders. Analysis was provided by Accelerate CIC Lymphoedema & Leg Ulcer Clinic. RESULTS A total of 2885 patients were reviewed via an online or a paper audit tool. In total, 2721 patients had one or more active wounds. However, 1350 patients had one or more lower leg wounds, with 164 patients being managed for lower limb swelling or prevention of leg ulceration; bilateral conditions ranged from 11-43% across audit sites. Of the six sites, two included both community and primary care providers, thus generating wound point prevalence data. The remaining four sites audited community nursing and podiatry services only, with two sites collecting data on lower limb wounds only rather than all wounds, generating point prevalence for their services only. Compression usage varied across care locations, with the greatest use being seen in community leg ulcer clinics, where it was >96% for 234 residents. Compression usage was lower in the home with a range of 14-62% among 692 residents. For 263 residents, where the cause of their lower leg wound was unknown, compression usage was very low at 12%. Compression usage decreased with age; for three audit sites this was noteworthy, with 65% of those aged >80 years not in receipt of compression. Compression usage had a direct impact on nursing activity; non-use of compression increased activity by 37%. CONCLUSION Through the identification of wound location, this series of wound prevalence audits identified a greater number of patients with lower limb wounds than those recognised and classified as a leg ulcer. Substantial variation in access to diagnostics and compression therapy was observed between audit sites, and also between locations within their boroughs. The factors that reduced access to compression therapy included not classifying the lower leg wound as a leg ulcer, being cared for in the home and increasing age of the patient. Lack of compression usage increased nursing activity. Where there is lack of access to therapeutic intervention, the resultant patient harm is not systematically recognised or documented.

Abstract
Hard-to-heal wounds are a problem for both patients and caregivers. The biofi lm is one of the local factors of delayed healing. Wound hygiene carried out in 4 steps (cleansing, debridement, refashion - care of the edges, and dressing) constitutes the basis of proactive and curative anti-biofi lm strategies.

Abstract
Cell regenerative therapy is a modern solution for difficult-to-heal wounds. Keratinocytes, the most common cell type in the skin, are difficult to obtain without the creation of another wound. Stem cell differentiation towards keratinocytes is a challenging process, and it is difficult to reproduce in chemically defined media. Nevertheless, a co-culture of keratinocytes with stem cells usually achieves efficient differentiation. This systematic review aims to identify the secretions of normal human keratinocytes reported in the literature and correlate them with the differentiation process. An online search revealed 338 references, of which 100 met the selection criteria. A total of 80 different keratinocyte secretions were reported, which can be grouped mainly into cytokines, growth factors, and antimicrobial peptides. The growth-factor group mostly affects stem cell differentiation into keratinocytes, especially epidermal growth factor and members of the transforming growth factor family. Nevertheless, the reported secretions reflected the nature of the involved studies, as most of them focused on keratinocyte interaction with inflammation. This review highlights the secretory function of keratinocytes, as well as the need for intense investigation to characterize these secretions and evaluate their regenerative capacities.

Abstract
The clinical and economic burden associated with hard-to-heal wounds is high and evidence suggests that it continues to increase. Healthcare resources consumed during the provision of wound care can be saved by implementing strategies and actions aimed at promoting wound healing. When these are successful, the frequency distribution curve for time to healing and for the consumption of healthcare resources should 'move to the left' and the extent to which it is 'skewed to the right' would be reduced, resulting in a reduction in the population mean for time to wound healing, and correspondingly, healthcare resources. Not only would this release healthcare resources in the short term, but, if these changes are maintained, would render savings sustainable, thereby contributing to lowering the overall burden of wounds and wound care. In this article, we present evidence that suggests that the adoption of adjunct topical haemoglobin spray can effect these desired changes in the wound healing curve and, due to the nature of the technology, it can be easily and sustainably implemented within relevant whole populations requiring wound care. The ease of adoption and impact is further illustrated by a patient case study.
