Burns are a major cause of morbidity in Yemen, and their prevention relies heavily on community knowledge and safe practices. Understanding gaps in awareness and behaviour is essential for designing effective interventions. This study assessed the knowledge, attitudes and practices (KAP) regarding burn prevention and first aid among a Yemeni community. A cross-sectional survey was conducted among 380 participants using a structured questionnaire distributed via social media and community networks. Data were collected on demographics, educational level, occupation, residential area and KAP related to household, electrical and chemical burns. Associations between participant characteristics and burn-related KAPs were analysed. Participants were predominantly female (63.7%), aged 15–45 years (79.8%), urban residents (92.9%) and university-educated (82.1%). Healthcare workers comprised 50.8% of respondents. Knowledge of burn prevention and first aid was highest among university-educated and healthcare participants, with 84.6% correctly identifying initial burn management. Unsafe practices, such as applying honey or toothpaste and improper handling of chemical or electrical injuries, were more common among less-educated, rural and nonhealthcare respondents. Urban participants demonstrated better preventive practices, while cultural reliance on traditional remedies persisted across all groups. Among predominantly urban and educated populations in Yemen, knowledge and attitudes toward burn prevention and first aid are generally favourable; however, gaps persist, particularly in rural and less-educated communities. Cultural practices and misconceptions continue to limit optimal care. These findings underscore the urgent need for culturally sensitive, literacy-appropriate, community-based interventions to improve burn prevention, first aid practices and equitable health outcomes.
Scar outcomes are known to vary by skin tone and race, yet few studies have systematically evaluated these differences using validated tools. To evaluate differences in scar maturation across Fitzpatrick skin types and racial groups from 3 to 12 months postoperatively using the modified Patient and Observer Scar Assessment Scale (POSAS) scale. We conducted a prospective observational study of 40 patients undergoing breast surgery at a single academic centre. All scars were assessed at 3 and 12 months postoperatively using the modified POSAS. Fitzpatrick skin types were categorized into I–II, III–IV, and V–VI, and racial groups included Caucasian, Black, and Hispanic patients. Fitzpatrick Types I–II had the greatest vascularity reduction (–2.06 ± 2.10), while Types V–VI showed the least improvement (–0.80 ± 1.61). Pigmentation increased in Types V–VI (+0.35 ± 1.89) and improved in lighter skin tones. Black and Hispanic patients had significantly lower odds of favourable pigmentation outcomes (p < 0.07). Fitzpatrick Types V–VI also had lower odds of improved scar relief (OR = 0.125, p = 0.034). This study highlights differences in scar maturation across skin tone and racial categories using a standardized scale. These trends underscore the importance of tailoring postoperative scar counselling and interventions to individual patients’ skin types and racial backgrounds.
Pressure injury (PI) is common in the ICU and not well captured by single-risk tools such as the Braden scale. We aimed to develop and internally validate a machine-learning model to predict new-onset PI using routinely collected ICU data. This retrospective single-centre cohort included adult ICU patients with length of stay ≥ 48 h (2018–2023). The primary outcome was new-onset PI during ICU stay. Candidate predictors were pre-specified: minimum albumin, maximum lactate, SOFA, APACHE II, first recorded Braden score, age, BMI, a nutrition score and treatment indicators. Missing values were imputed (median/mode). A gradient boosting model (GBM) was evaluated with stratified 3-fold cross-validation; a random forest (RF) served as a benchmark (stratified 70/30 train–test split). Discrimination (AUC) was primary; calibration, Brier score, decision-curve analysis (DCA) and feature importance were secondary. Logistic regression quantified independent associations. Among included ICU stays, 14.6% developed PI. On multivariable analysis, higher lactate, lower albumin, lower Braden scores, older age, CRRT, prone positioning, enteral nutrition and analgesic exposure were associated with increased PI risk, whereas sedatives showed an inverse association. The GBM achieved AUC≈0.69 with acceptable calibration and net clinical benefit across thresholds commonly used in preventive workflows (≈0.10–0.50). Single markers or simple combinations displayed only modest discrimination. A GBM built from routine ICU data provided moderate, well-calibrated discrimination for predicting new-onset PI and demonstrated decision-relevant net benefit. The model can complement Braden-based screening by refining risk stratification and prioritising intensified prevention for patients most likely to benefit. External validation and prospective evaluation are warranted.
Hidradenitis suppurativa is a chronic inflammatory skin disorder causing painful nodules, abscesses and scarring, with the anogenital region presenting particular functional and reconstructive challenges. Although biologic therapy is commonly used in moderate to severe disease, its limitations highlight the role of surgery in advanced cases. This single-centre retrospective case series included five male patients with Hurley stage III perineal, anorectal, genital or gluteal disease treated surgically between 2021 and 2023 following failure of biologic therapy. Management consisted of two-stage radical excision, negative-pressure wound therapy and reconstruction with meshed split-thickness skin grafts. All patients achieved more than 90% graft take and complete wound healing. No recurrence occurred during a median follow-up of 19.2 months. One patient developed a keloid scar at the donor site, and one experienced delayed healing. Functional and aesthetic results were satisfactory in all cases. Two-stage surgical excision with split-thickness skin graft reconstruction was associated with sustained wound healing and favourable functional outcomes in selected patients with severe anogenital hidradenitis suppurativa refractory to biologic therapy.
Hand burns, although often limited in surface area, have a major impact on function and quality of life. Debridement—surgical or enzymatic—is a key component of treatment, with enzymatic debridement increasingly used for its selectivity and potential to preserve viable dermis. To evaluate and compare the functional outcomes of hand burns treated with surgical versus enzymatic debridement, using the DASH/Quick-DASH and Michigan Hand Questionnaire (MHQ) assessment tools. A systematic review was conducted according to PRISMA guidelines and registered in PROSPERO (CRD420251034408). Searches were performed in PubMed, Scopus, and Web of Science without date restrictions. Inclusion criteria focused on studies evaluating hand burn function using DASH, Quick-DASH, or MHQ after enzymatic or surgical debridement in patients aged 16 or older. Methodological quality was assessed using the ROBINS-I tool. Of 547 studies identified, 7 met inclusion criteria: 4 surgical and 3 enzymatic. Functional recovery was generally better in cases where enzymatic debridement preserved viable dermis and avoided grafting. DASH and MHQ scores favoured enzymatic approaches, especially when conservative management followed debridement. However, methodological limitations and clinical heterogeneity limited direct comparison. Enzymatic debridement, through preservation of viable dermis and reduced grafting need, appears associated with improved functional outcomes in hand burns. Whilst surgical debridement remains essential for deeper burns, enzymatic methods may offer functional advantages and support early rehabilitation in appropriate cases.
This study aimed to explore informal caregivers' (family members of patients) perspectives on their involvement in ongoing multidisciplinary treatment of diabetes-related foot ulcers in a highly specialised outpatient service with a multidisciplinary team structure that was still evolving. Using focus group interviews and template analysis, we identified patterns in caregivers' experiences, needs, and preferences. The findings suggest considerable potential to improve patient care through earlier caregiver involvement. While some caregivers reported positive experiences, many rarely or never attended consultations and struggled to define involvement in practical terms. However, caregivers consistently expressed a strong wish for earlier involvement—ideally at the time of diabetes diagnosis—to acquire the knowledge and skills needed to support patients between clinical visits. Caregivers play an important role in foot ulcer management, as complex regimens such as wound care, offloading, and lifestyle adjustments require ongoing support outside clinical settings. However, involvement may also create strain. Participants described emotional and practical burden, feelings of guilt, and uncertainty about their roles. The study highlights the need for structured caregiver education, clear communication, and systemic support to balance the benefits of caregiver involvement with the risk of caregiver burden.
Pressure injury represents a significant but preventable health problem, especially in clinical settings characterised by a high degree of risk. Despite the critical role played by nurses in pressure injury prevention, evidence suggests that inconsistencies remain concerning their knowledge and skill levels. This study aimed to determine the level of knowledge amongst nurses regarding pressure injury prevention and the factors associated with this level. The sample of this cross-sectional study consisted of 346 nurses reached through convenience sampling. The research data were collected online using the nurse descriptive form and the Pieper–Zulkowski Pressure Injury Knowledge Test, accessed through a Google Forms link shared on various social media platforms between December 2023 and February 2025. Most of the 346 nurses who participated in the study were female (89.0%), and the mean age was 36.19 years (±8.52 years). Most participants had a bachelor's degree (76.8%), and 35.6% had more than 20 years of professional experience. The pressure injury knowledge test score of the nurses was 43.00 (10.50). There was a significant difference in knowledge scores between clinical units (p = 0.009); the highest scores were found in nurses working in high-risk units (e.g., operating theatre) (p = 0.029). The study demonstrated that the implementation of unit-specific, practise-based training programmes is imperative to enhance nurses' knowledge. It is suggested that future studies utilise a combination of methods in order to address the individual, environmental and organisational factors that have a bearing on knowledge levels.
Hyperbaric oxygen therapy (HBOT) enhances wound healing by promoting angiogenesis and reducing hypoxia. However, the role of air-breaks—intermittent exposures to ambient air during HBOT—remains unclear. We investigated the effects of air-breaks on HBOT-mediated wound healing, particularly in combination with adipose-derived stromal cells (ASCs). Full-thickness wounds were created in C57BL/6 mice (n = 36) and assigned to control, HBOT (1 h/day, 2 ATA for 11 days), or HBOT with a 10-min air-break groups. In a second experiment, we evaluated ASC treatment combined with HBOT and air-breaks. Wound healing was assessed via gross examination, histology and gene expression analysis of collagen type 1 alpha 1 (Col1a1), hypoxia-inducible factor 1 alpha (Hif1a) and tumour necrosis factor (Tnf-α). Compared with HBOT alone, air-breaks significantly improved wound closure, epithelial regeneration and collagen deposition (p < 0.05). Gene analysis showed higher Col1a1 expression and lower Hif1a and Tnf-α levels in the air-break group. In ASC-treated wounds, air-breaks further accelerated healing, enhancing collagen synthesis and reducing hypoxia and inflammation. These findings suggest that incorporating air-breaks into HBOT protocols improves wound healing outcomes, both generally and in ASC-based therapies, by modulating collagen production, hypoxia and inflammation, and could optimise HBOT efficacy, particularly in cell-based regenerative therapies.
Chronic wounds pose a substantial global health challenge, marked by persistent inflammation, infection, hypoxia, and impaired tissue regeneration. Traditional oxygen-based therapies, including hyperbaric and topical oxygen treatments, often suffer from limited efficacy, high costs, restricted accessibility, and difficulties in achieving sustained oxygen delivery. In contrast, microalgae offer a promising and sustainable alternative, owing to their biocompatibility, glucose consumption, and continuous oxygen production via photosynthesis. Innovative delivery platforms, such as hydrogels, scaffolds, sutures, microneedles, and microrobots, have demonstrated enhanced wound healing by mitigating hypoxia, reducing infection, and modulating inflammation. Recent advances in genetic engineering and 3D bioprinting further enhance the therapeutic potential of these systems. This review explores current progress in microalgae-based wound healing approaches, with a particular focus on photosynthesis-driven oxygen delivery technologies.
To assess the potential for microbial contamination of open-but-unused portions of wound dressings stored under real-life conditions in healthcare facilities, to inform safer and evidence-based wound care practices. Observational, descriptive, longitudinal, prospective study. Eleven types of non-adhesive wound dressings were sampled after opening and storage under usual clinical conditions in a hospital inpatient unit and a primary care centre in Andalusia, Spain. Samples were collected on six predefined sampling days (Days 0, 2, 3, 4, 5 and 6 after opening), cultured under standardised laboratory conditions and microorganisms were identified using mass spectrometry. Differences in contamination were examined by dressing type, healthcare setting, storage time and handling conditions. Microbial growth was frequently detected in open-but-unused dressings from the first day after opening, particularly after enrichment culture and increased with handling and time. The most frequent microorganisms were coagulase-negative staphylococci and Staphylococcus aureus. Contamination patterns were similar across settings, although microbial diversity was higher in the hospital. Silver-containing dressings showed slightly lower contamination, but not enough to indicate protection. Scissors used for cutting dressings had high microbial loads, suggesting a potential source of cross-contamination. Open-but-unused dressings may become contaminated shortly after opening under routine clinical practice conditions, across different healthcare settings and dressing types.
Negative-pressure wound therapy (NPWT) is widely used in clinical practise to enhance wound healing; however, its biological effects on intact skin remain poorly understood. Given the expanding applications of NPWT, understanding its impact beyond open wounds is increasingly important. This study aimed to evaluate the biological responses of intact skin to negative-pressure, specifically focusing on epithelial-mesenchymal transition (EMT). The effects of negative-pressure loading were assessed using an in vitro model of non-diabetic human keratinocytes and an in vivo model of intact diabetic mouse skin. Human keratinocytes exposed to negative-pressure exhibited increased expression of thrombospondin-1 (THBS1), transforming growth factor-beta 1 (TGF-β1), plasminogen activator inhibitor-1 (PAI-1), and hypoxia-inducible factor 1-alpha (HIF-1α), alongside decreased epithelial markers and increased mesenchymal markers. These EMT-related changes were mitigated by inhibiting the THBS1-TGF-β1 interaction. Similarly, in diabetic mice, intermittent negative-pressure loading applied to intact dorsal skin significantly increased THBS1 and TGF-β1 levels, resulting in epidermal and dermal thickening, and promoted hypoxic, prothrombotic and angiogenic responses, as evidenced by increased HIF-1α, PAI-1, fibrinogen and vascular endothelial growth factor expression. These findings suggest that negative-pressure loading can induce EMT-like responses and tissue remodelling in intact skin primarily via mechanisms involving the THBS1-TGF-β1 signalling axis. This study expands the understanding of the biological influence of NPWT beyond traditional wound treatment applications, potentially informing future therapeutic considerations and safety guidelines.
Venous leg ulcers (VLU) are a major complication of chronic venous disease, with compression therapy as the gold-standard treatment. This 2 × 2 factorial randomised open-label trial assessed the effect and three-month sustainability of a one-hour training intervention on compression bandaging quality among 50 advanced practice nursing students (APNS) in France, using two different compression bandage types (system A or system B) on a mannequin leg. The primary outcome was the Control Score of compression bandaging (CCB score, 0–7). Secondary outcomes included installation conformity, application time, and satisfaction. At baseline, mean CCB score was 3.78, with 52% installation conformity. The intervention did not significantly improve the CCB score compared to controls (adjusted difference: −0.43; 95% CI: −1.01 to 0.15). A significant interaction between bandage type and intervention was found for installation conformity: a tendency to improve with system B and decrease with system A. Improvements observed at 1 month were not sustained at 3 months. Application time decreased over follow-up, and system B was applied more efficiently than system A. Brief, behaviourist-based training was insufficient to achieve lasting skill improvement. Findings highlight the need for repeated group practice, feedback, and integration into relevant clinical contexts to enhance compression bandaging proficiency.
To measure and compare the temporal variations in sub-bandage pressure compression systems in the Andalusian Health System (SAS). Additional objectives included assessing the relationship between pressure and healing, analysing the influence of the healthcare professional applying the bandage, and determining bandage stiffness. This prospective observational and multicentre study included 140 patients with active VLUs in Andalusia. Sub-bandage pressures were measured at three anatomical points in the leg for 96 h, under different positions and activities. The bandage application technique was standardised through specific training provided to advanced practice nurses. The initial pressures were higher than those recommended by guidelines, but showed a notable reduction within the first 24 h, stabilising within therapeutic ranges for the remainder of the 96-h study period. Most systems showed low dynamic and static stiffness. No significant pressure differences were found attributable to the nurses or the location of the injury. The observed pressure dynamics, initially high, with a subsequent drop and final stabilisation, suggest a high material settlement or application to compensate for the expected loss. The sustained pressure stability confirms the effectiveness of the systems over 96 h.

The ‘Wound Hygiene Italia’ project was designed to provide expert-driven recommendations for the assessment, management and monitoring of venous leg ulcers, tailored to diverse settings of care (hospital, ambulatory and home care). The recommendations, developed by a multidisciplinary panel, emphasise the implementation of the Wound Hygiene strategy, a systematic approach targeting biofilm as a primary barrier to wound healing. Wound management is structured around four steps: cleansing, debridement, edge refashioning and dressing selection adapted to the wound bed characteristics, care setting and clinical capabilities, embedded in a holistic approach through comprehensive patient assessment and monitoring of overall well-being. The findings highlight the necessity of interdisciplinary collaboration, standardised tools and continuous patient monitoring, as assessed by objective metrics, such as wound size measurements and photographic documentation. Effective communication with patients and caregivers is also essential to ensure treatment adherence and foster trust in the care process. This framework integrates evidence-based practices to optimise outcomes and patient quality of life. By addressing both clinical and psychosocial factors, the recommendations promote a holistic, patient-centred approach that underscores the importance of education, structured follow-ups and tailored interventions.
Exosome therapy has emerged in recent years as a promising acellular approach for the treatment of tissue regeneration and wound healing. Initial preclinical investigations have demonstrated accelerated fibroblast proliferation, improved angiogenesis and reduced scar formation. It is evident that patients are more likely to gain an understanding of these treatments and acquire information from digital platforms as opposed to from peer-reviewed scientific publications. This study assessed the credibility and instructional merit of exosome therapy content on YouTube, a prominent source of online health information. A cross-sectional study was performed on the initial 50 videos in English obtained using the keyword ‘exosome therapy’ (15 July 2025). The videos were independently assessed by two plastic surgeons and a dermatologist using three validated scoring systems. The scoring system was based on the Journal of the American Medical Association (JAMA) reference criteria for transparency and reliability, the Global Quality Score (GQS) for overall educational quality and the modified DISCERN tool for content reliability and balance. The median scores obtained were consistently low (DISCERN: 2.67; GQS: 2.67; JAMA: 2.00). However, videos created by doctors exhibited a statistically significant higher average score compared to videos published by patients, companies and YouTubers (p < 0.05). A robust positive correlation was identified between DISCERN and GQS (ρ = 0.95, p < 0.001). Despite the substantial experimental evidence that confirms the efficacy of exosome therapy for acute and chronic wounds, none of the videos addressed the recognised wound healing applications of exosome therapy. In contrast, the contents primarily focus on cosmetic enhancement, anti-ageing interventions and beauty-related applications. The discrepancy between the scientific advancements in the fields of regenerative medicine, dermatology and plastic surgery and the accessibility of online educational resources, highlights the necessity for professional health organisations to furnish accessible, evidence-based materials that accurately demonstrate the therapeutic potential of exosomes in wound healing.
Negative pressure wound therapy (NPWT) is widely used to facilitate healing by improving local perfusion, reducing edema and controlling exudate. The porous foam dressing is central to NPWT effectiveness, however, its performance in viscous, particle-rich exudates remains challenging. Standard industry tests often rely on protein-free aqueous solutions, which overlook the complex rheology and particulate load of real wounds. This study reports a bench evaluation of a multilayer foam prototype compared with three commercial dressings under NPWT, using a simulated viscous exudate with suspended particles. We recorded 60-min drainage curves and quantified effluent turbidity as a simple, interpretable proxy for particulate transport, summarised as percentage of input turbidity recovered. The mass-based endpoint (percent solid matter recovered) showed the same ranking as turbidity. At −75 mmHg, the prototype recovered 31.6% of input turbidity, exceeding commercial foams (≤ 9.7%). At −125 mmHg, particulate recovery decreased across all dressings (≤ 9.1%). A matrix-only control indicated that commercial effluents, particularly at −75 mmHg, clustered near background level, whereas the prototype evacuated substantially more particulate while maintaining robust fluid drainage. These findings suggest that moderate negative pressure and multilayer architecture can help preserve channel patency and reduce clogging in complex exudates. We highlight the need for test methodologies that incorporate viscosity and particulate content, and for practical guidance that links dressing architecture and pressure settings to exudate characteristics. Prospective validation, including larger-sample confirmation, particle-size distributions and ultimately clinical endpoints, is warranted.
