The aim in this human trial is to compare the efficacy and safety of polygalacturonic–caprylic acid (PG–CAP) ointment to MediHoney in chronic wounds at three international medical centres. In this prospective open-label study, patients with chronic full-thickness wounds were randomised to daily treatment with PG–CAP ointment or MediHoney. Assessments were obtained weekly for 6 weeks. The validated Pressure Ulcer Scale for Healing (PUSH) score was used to track healing. Efficacies were compared using the Wilcoxon rank-sum test for continuous variables and chi-square or Fisher's exact test for categorical variables. Twenty-six patients with chronic wounds were included. Baseline characteristics were comparable between the groups; however, the history of diabetes mellitus was higher in the PG–CAP group (p = 0.011). All 13 PG–CAP patients showed improvement (100%), compared to only 69% of the 13 MediHoney patients (p = 0.023). Half of the failures in the MediHoney arm were associated with death (15%). No failures, adverse events or deaths occurred in the PG–CAP arm. PG–CAP wound ointment is a novel combination of two plant-based compounds that pose minimal risk of promoting antimicrobial resistance, was highly effective for eradicating wound-pathogen biofilms in vitro and promoted chronic wound healing in vivo with minimal inflammatory reactions. Our findings support PG–CAP as safe, noninferior and possibly more effective than MediHoney in healing chronic contaminated wounds.

Pressure injuries (PI) acquired during surgical procedures remain a serious and under-recognised patient safety concern. Operating room nurses play a critical role in PI prevention; however, their knowledge and attitudes towards preventive practices are often suboptimal and under-explored in the literature. This study aimed to assess the knowledge and attitudes of operating room nurses towards PI prevention and to examine the relationship between the two. This descriptive cross-sectional study included 208 operating room nurses from a city hospital in Istanbul, Turkey, between December 2022 and February 2023. Data were collected using the Modified Pieper Pressure Ulcer Knowledge Test (MPPUKT) and the Attitude Towards Pressure Ulcer Prevention Scale (APUP). Descriptive statistics, Pearson correlation and linear regression analyses were performed using SPSS 25.0. The mean MPPUKT score was 26.63 ± 12.43 (54.5%), with 56.7% of participants scoring below 60%, indicating inadequate knowledge. The lowest subscale scores were observed in staging (44.3%) and wound diagnostics (51.4%). In contrast, the mean APUP score was 38.33 ± 5.38, indicating a generally positive attitude, with the highest scores in the Priority and Impact subdimensions. A moderate, significant positive correlation was found between knowledge and attitude (r = 0.275, p < 0.001). Linear regression analysis confirmed that knowledge significantly predicted attitude scores (β = 0.275, p < 0.001), explaining 7.6% of the variance (R² = 0.076). While operating room nurses exhibit positive attitudes towards PI prevention, their knowledge—particularly in staging and wound assessment—is insufficient. Structured, competency-based educational programmes focusing on high-risk areas may enhance nurses' knowledge and foster more proactive preventive behaviours. Hospital systems should prioritise recurrent training and supportive strategies to promote evidence-based PI prevention practices in surgical settings.

Assessing and treating a patient's wound is something that every medical student may be faced with from day one of their postgraduate clinical career, regardless of their chosen field of specialisation. This includes acute or post-surgical wounds as well as chronic wounds. In contrast, learning content concerning wound care is currently underrepresented in medical school curricula, although there are many possible topics and options to incorporate this subject into medical teaching. As a first step in curriculum development, this study provides a comprehensive yet clinically relevant catalogue of possible learning objectives for medical students in wound care. An interprofessional and interdisciplinary group of wound care experts collected a first draft of learning objectives. Then a group of clinicians from 16 different medical specialties was consulted to additionally rate the relevance of each proposed learning objective. By this approach, a consensus catalogue of 32 relevant learning objectives in wound care for medical students was developed. Furthermore, varying perspectives of experts and clinicians on wound care topics and their relevance for medical students were identified. The findings of this study will facilitate future discussions about implementation of wound care content into medical curricula.

The study aimed to translate the PUKAT 2.0 tool from English to Italian. This was an adaptation and validation study; the validity of the Italian version was determined through content validity, item validity and construct validity. The reliability of the instrument was assessed by conducting a test–retest analysis on a sample of 62 nurses. The I-CVI indices were above the threshold of 0.78 for 91% of the questions, and according to the S-CVI index, 96% of the evaluators agreed that the questionnaire was highly relevant. The overall values for item difficulty were good, with two items being too difficult and none being too easy. The item discriminant index was overall good and reasonable, low for four items. The overall ICC was poor to moderate with a value of 0.48 (95% CI 0.26–0.65). The instrument has proven to be a good starting point although not yet completely reliable, as it clearly requires more basic preparation on the part of the staff, further modifications regarding the reliability and clarity of the questions and more training of the nursing staff if it is to be used in the Italian context.

A comprehensive skincare regimen involves cleansing, moisturising, and using skin barrier protectants. Cyanoacrylate-based protectants safeguard vulnerable skin from damage caused by moisture, friction, and shear. This research involved two ex vivo and two clinical studies comparing the wear duration and wash-off resistance of a 100% cyanoacrylate and a solvent-cyanoacrylate mixture. Effectiveness was assessed using an ex vivo porcine skin model simulating urinary incontinence, evaluated with Lucifer yellow dye penetration and Corneometry, and a clinical model using Corneometry. Two single-blind clinical studies measured skin surface electrical capacitance in healthy volunteers. Study 1 (n = 42) evaluated the wear duration over 8 days, while Study 2 (n = 52) examined wash-off resistance after nine washes with various cleansers. Ex vivo results showed that both products were effective under repeated moisture and abrasion conditions, with the 100% cyanoacrylate outperforming the solvent-cyanoacrylate mixture. In clinical studies, both products maintained barrier protection throughout Study 1 (p < 0.007) and none of the cleansers significantly degraded either product in Study 2. In conclusion, the 100% cyanoacrylate provided superior protection compared to the solvent-cyanoacrylate mixture. Both products demonstrated comparable wear duration and wash-off resistance in clinical studies, but the 100% cyanoacrylate was more effective in ex vivo testing under harsh conditions.

Complex chronic wounds are an increasing health concern, affecting individuals both physically and psychologically. To measure the quality of life of this population properly translated and validated questionnaires in their native language are needed. The aim of this work is to provide a validated instrument for measuring the quality of life in the Catalan speaking population with complex wounds. A cultural adaptation of the Wound-QoL-17 questionnaire into Catalan was carried out by independent official translators and the back translation was approved by the original author. Validity, reliability, responsiveness, and feasibility were assessed. Face and content validity were determined by a group of experts: the 17 items of the Wound-QoL-17 Catalan version were appropriate for their purpose. Reliability was demonstrated by an interclass correlation coefficient of 0.884 for the scores obtained by two different observers and of 0.928 for the same observer on two time points. Chronbach's alpha coefficient was 0.926. Responsiveness was proved by a Pearson's correlation coefficient of 0.661. Feasibility was shown by the time, 3.46 min, taken to complete the questionnaire.

The treatment of chronic wounds in the Aged is often difficult. Masquelet technique is used for the treatment of infected large segmental bone defects as it provides an adequate blood supply for bone and soft tissue reconstruction. In this study, a two-stage wound management strategy was used, consisting of covering the initial wound with bone cement and skin grafting under induced membranes. From September 2020 to September 2022, 20 Aged patients with chronic refractory wounds of the lower extremities with exposed bone or tendons were recruited in the Department of Wound Repair Surgery of the Second Affiliated Hospital of Wenzhou Medical University. Each patient was reconstructed according to a two-stage process. In the first stage, while treating the patient's underlying disease, several debridements were first performed on the wound; subsequently, the Masquelet technique was applied to seal the wound with antibiotic bone cement. Four to 6 weeks later, the second stage was initiated—after confirming the sufficient formation of wound induced membranes, the bone cement was removed, and free skin grafts were finally used to cover the chronic refractory wounds on the extremities. The area of the defects ranged from 4.5 × 3.0 cm to 15.0 × 6.0 cm, and all soft tissue defects were associated with tendon or bone exposure. After the surgery, patients attended regular outpatient visits and were followed up by telephone and video to observe the healing of the wounds and whether there were any complications in the donor site. The Lower Extremity Function Scale (LEFS) score was used to evaluate the functional recovery of the lower extremities. We found that all implants survived without necrosis or infection. All 20 cases were followed up regularly after surgery for 3 to 12 months, with a mean of 7.6 months. In the first stage, Induced Membranes induction was performed 1–4 times, with an average of (1.3 ± 0.7) times, and in the second stage, free skin grafting was performed on the induction membrane, and all 20 cases of skin grafting survived without necrosis or infection; the appearance and texture of the skin in the grafted area were satisfactory, and the postoperative LEFS score was (69.83 ± 10.82). Finally, our strategy for the management of chronic refractory wounds in the Aged can achieve satisfactory clinical results, reduce surgical risk, be simple and reliable, and be an effective addition to the repair modality.

A lack of murine models that mimic impaired wound healing in people with type 2 diabetes has hindered research. The commonly used leptin-receptor knockout model (db/db) fails to accurately reflect the pathophysiology of human disease. This study aimed: (i) to investigate whether our novel murine model of diabetes, whilst less hyperglycaemic and obese than db/dbs, effectively demonstrated impaired wound healing, and (ii) to identify the most robust methods for quantifying wound closure. C57BL/6J mice were high-fat diet fed for a total of 11 weeks and injected with three doses of streptozotocin (65 mg/kg body weight) at week 5 with chow-fed mice as controls. All mice received four excisional wounds and were euthanised at day-4 or day-10 post-wounding (n = 8/group/timepoint). Wound healing was evaluated by digital planimetry, histology, Micro-CT, and tensiometry. Histological analysis was the most sensitive method for identifying impaired wound healing. Our high-fat diet/low-dose streptozotocin model had significantly higher non-fasting blood glucose (25.7 ± 5.4 mmol/L vs. 8.7 ± 0.8 mmol/L) and lower wound quality scores (day-4 post-wounding: 2.6 ± 1.9 vs. 4.4 ± 0.8) than healthy controls (both p < 0.05). At day-10 post-wounding, a linear trend in wound healing was observed between healthy controls, our novel model and the db/db model, indicating that our diabetic murine model may be clinically relevant for studying diabetes-related wound healing.
