Burn patients receiving split thickness skin grafting are left with scarring and chronically dysfunctional grafted skin. Given evidence that patients' preoperative expectations mediate postoperative outcomes and satisfaction, we described burn patients' experience, expectations, and satisfaction with their skin graft, their views towards a cell based clinical trial to improve their graft and identified graft outcome measures for use in future studies. ⋯ Outcome measures in trials advancing skin grafting should reflect chronic, patient prioritized limitations. We recommend preoperative educational interventions for burn patients receiving grafting to improve postoperative satisfaction.

Quick, easy access to data-driven community risk assessment principles and to related community risk reduction activities can encourage fire departments to learn about, conduct, and complete district risk reduction practices. With the ultimate goal of creating web-based community risk assessment and community risk reduction resources, we first evaluated fire department needs. ⋯ Respondents described data use for community risk assessment and for planning community risk reduction activities; how a lack of time, personnel, and funding impacts community risk assessment and community risk reduction activities; and how to involve both firefighters and the community in the process. Innovative solutions such as a website containing resources on how to assess community risk information along with resources such as community risk assessment/ reduction education, program planning, and tools, can assist departments to use community risk assessment data in the development of community risk reduction activities.

To assess the readability, accountability, and quality of burns first aid information available online. ⋯ Much of the burns first aid information available online is written above the recommended reading level and fails to meet standards of accountability or quality.

Skin scarring is a frequent complication of the wound healing process. Bacterial contamination and prolonged inflammation in wounds are thought to play significant roles during scar formation, but little is known about their specific mechanisms of action. In this study, hypertrophic scar derived fibroblasts (HSFs) and paired normal skin derived fibroblasts (NSFs) were used to evaluate the effects of lipopolysaccharide (LPS) on inflammation-induced skin scarring and explore the inflammation-mediated mechanism of activity of LPS on dermal fibroblasts. ⋯ Blocking Myd88 expression with T6167923 downregulated the expression of Col I, Col III, and α-SMA, whereas activating Myd88 expression with CL075 significantly upregulated their expression in LPS-treated NSFs. LPS was found to delay wound healing and increase skin scarring in cell and mouse models. These results showed that LPS could induce scar formation through the TLR4/Myd88 signaling pathway in dermal fibroblasts, suggesting that the downregulation of excessive inflammation in wound tissues inhibits skin scarring and improves scar appearance.

Exosomes and hyaluronic acid influence tissue regeneration and may be used as an alternative to more conventional wound treatment methods. This study compared how well hyaluronic acid from the human umbilical cord and exosomes from fibroblast cells heal burn wounds in a preclinical model. ⋯ The results showed that hyaluronic acid and exosomes improved wound healing. Also, the study demonstrated that hyaluronic acid has better effects in the re-epithelization. The exosome was more effective than HA in eschar formation. Both compounds were more influential in the PMNs and LYMs parameters than other groups. The combination of both compounds should be assessed further to achieve better therapeutic effects on wound healing.
