Purpose: To investigate the knowledge, attitudes and practices of intensive care unit (ICU) nurses regarding acute skin failure (ASF) and analyse the influencing factors thereof.

Methods: From 22 December 2023 to 24 January 2024, a cross-sectional study was conducted amongst ICU nurses from 21 hospitals in eight provinces in China. The ASF knowledge, attitude and practice scores were determined using questionnaires, and multiple linear regression was used for further analysis.

Results: Overall, 304 ICU nurses completed the survey. The knowledge, attitude and practice scores were 24.89 ± 10.93, 40.67 ± 5.93 and 43.47 ± 9.19, with scoring rates of 45.25%, 81.34% and 72.45%, respectively. Multiple linear regression analysis showed that being a wound ostomy specialist nurse was positively correlated with the knowledge dimension score (p < 0.05). Nurses' professional titles significantly affected attitude scores (p < 0.05); the higher the professional title, the more positive the attitude towards ASF.

Conclusion: The attitudes and practices of ICU nurses in China towards ASF were found to be positive; however, their knowledge levels need improvement. Nursing managers should conduct targeted training, especially for entry-level nurses.

Wound healing is a central physiological process that restores the barrier properties of the skin after injury, comprising close coordination between several cell types (including fibroblasts and macrophages) in the wound bed. The complex mechanisms involved are executed and regulated by an equally complex, reciprocal signalling network involving numerous signalling molecules such as catabolic and anabolic inflammatory mediators (e.g., cytokines, chemokines). In chronic wound environments, the balance in the molecular signatures of inflammatory mediators is usually impaired. Thus, we compared the ability of a collagen-based wound matrix against a synthetic wound matrix to attract fibroblasts and macrophages that deliver these signalling molecules. In particular, the balance between pro- and anti- inflammatory cytokine secretion was assessed. We found that the natural collagen-based matrix was the most efficient adhesive substrate to recruit and activate fibroblasts and macrophages on its surface. These cells secreted a variety of cytokines, and the natural biomaterial exhibited a more balanced secretion of pro- and anti-inflammatory mediators than the synthetic comparator. Thus, our study highlights the ability of native collagen matrices to modulate inflammatory mediator signatures in the wound bed, indicating that such devices may be beneficial for wound healing in the clinical setting.

Good foot care knowledge and behaviour are very important to prevent the occurrence of diabetic foot, but there are few reports on the foot care knowledge and behaviour of older people with diabetes in the community. The purpose of this study was to understand the foot care knowledge and behaviour of older people with type 2 diabetes in Beijing community, and analyse its influencing factors, so as to provide reference for further intervention. We investigated 254 older people with type 2 diabetes in Xinjiekou community, Beijing, including their general information, chronic complications, foot care knowledge and behaviour. The results showed that the average scores of foot care knowledge and behaviour were 73.38 ± 12.25 and 49.70 ± 8.70, respectively. Multiple stepwise regression analysis showed that the factors affecting the total score of foot nursing knowledge of older people with diabetes in community were gender, duration of diabetes and whether they had received foot nursing education (p < 0.05). The factors influencing the total score of foot nursing behaviour were gender, duration of disease, whether they had received foot nursing education and peripheral vascular disease (p < 0.05). In conclusion, the knowledge of foot care of older people with diabetes in community is in the middle level, and the foot care behaviour is not optimistic. Community healthcare workers can improve patients' knowledge of foot care and improve their compliance with foot care behaviour through foot care health education. At the same time, we should pay more attention to men, those with a shorter duration of diabetes and diabetic patients with peripheral vascular disease to reduce the occurrence of diabetic foot.

Diabetic foot wounds (DFW) are notoriously difficult to treat owing to poor vascularity, delayed healing and higher rates of infection. Human-derived acellular dermal matrices (ADM) have been used in DFW treatment, utilizing a matrix scaffold for new tissue generation. We investigate the efficacy of a micronized injectable human-derived ADM in the treatment of DFW. We retrospectively recruited 13 patients with diabetic foot wounds. Wounds were adequately debrided, and a micronized injectable ADM was applied. Wound sizes were recorded prior to treatment, at 2 and 4 weeks post-treatment. The mean defect of wounds treated was 19.21 cm³. Our results showed a statistically significant reduction in wound size of 45% and 59% at 2 and 4 weeks post-treatment, respectively (p < 0.01). ADM was also effective in infected DFW as 84% of our wounds had positive tissue cultures at the time of application. Micronized injectable ADM has proven to be an effective treatment for DFW. Advantages include a ready-to-use injectable, single-stage treatment, minimal pain, mouldable matrix to fit any wound shape, allows for outpatient treatment and simple wound dressings.

There are two major styles of maggot debridement dressings: (1) confinement dressings that form a cage around the wound, and (2) containment dressings that completely surround the maggots within a sealed porous bag. For producers and clinicians wanting to prepare containment dressings using readily available polyester bags, it is currently difficult to seal these bags without expensive high-temperature plastic welders. This study aimed to identify simple and affordable methods for sealing maggots within polyester net bags. Heat sealing was the most effective and simplest method to seal the polyester net bags, but the high melting point of polyester required industrial grade heat sealers. An inner lining of polyethylene or polypropylene film at the open side of the bag allowed for complete sealing using low-cost hand-actuated impulse heat sealers. This design even facilitated the addition of plastic zipper-locks, allowing secure closure of the bag without electricity or special equipment. Other sealing methods were identified, but most were time-consuming, required practice or not consistently successful. The maggot containment bag designs and closure methods described herein should prove useful to clinicians without access to contained maggots and to maggot producers without the resources to seal polyester containment bags. Clinical trials are expected to follow.

We aimed to compare the scar quality and recovery rate of joint activity for patients with joint-involved burn injuries receiving either artificial dermis (AD) with split-thickness skin graft (STSG) or full-thickness skin graft (FTSG) for reconstruction. The primary outcomes were %skin graft (SG) take. Secondary outcomes included complications such as the infection rate and donor site morbidity, 12-month scar quality evaluated using the Vancouver scar scale (VSS), recovery rate of joint activity and incidence of scar contracture requiring further revision. Twenty-eight patients between 1 August 2021, and 1 August 2023, were enrolled. Twelve patients received AD-STSG while the other 16 patients underwent FTSG for reconstruction. The median %SG take was 95.0% (interquartile range [IQR] 6.3%) and 96.0% (IQR 10.0%) for the AD-STSG and FTSG groups (p = 0.71). The FTSG group had significantly better 12-month scar quality (median VSS 4.0 [IQR 1.3] vs. 6.0 [IQR1.5], p < 0.01) and recovery rate of joint activity (median 82.5% [IQT 15.0%] vs. 70.0% [IQR 7.5%], p < 0.01) compared with AD-STSG group. However, two patients in the FTSG group (12.5%) suffered partial wound dehiscence of the donor site, whereas no patients experienced donor site morbidity in the AD-STSG group (p = 0.49). The incidence of scar contracture requiring further revision was 25.0% (3/12) in the AD-STSG group and 12.5% (2/16) in the FTSG group (p = 0.62). In conclusion, AD-STSG could be an alternative treatment over FTSG for larger joint-involved burn wounds (>200 cm²) owing to lesser donor site morbidity with admissible cosmetic outcomes and functional recovery.
