Allogeneic and xenogeneic skin are recognized as the best coverings for skin burn wounds, but currently face a supply shortage. To solve this problem, our research group developed a standardized manufactured hydrogel dressing based on a new type of highly bioactive recombinant human collagen. ⋯ During the observation period, the therapeutic effect of the RHCH developed by our group on partial-thickness burn wounds was not significantly different from that of gene-transferred xenogeneic skin. Thus, our designed RHCH shows potential for clinical use to treat burn wounds on the skin.

As recently as 2006, carburetor flash burns comprised as much as 27% of admissions for car-related burns, despite the fact carburetors were last installed in pre-1990 automobiles. The prevalence of this injury pattern is related to the estimated 14 million cars on the road today that were manufactured prior to that year. The aim of this study was to investigate modern sources of automotive burns and describe any new trends in automotive burn-related epidemiology. ⋯ Despite the removal of carburetors from engines and a decrease in this specific mechanism, a significant morbidity remains with gasoline-inflicted burns. More public awareness is needed for the safe removal of radiator caps and handling of chemicals in overheating engines.

Early mechanisms underlying the progressive tissue death and the regenerative capability of burn wounds are understudied in human skin. A clinically relevant, reproducible model for human burn wound healing is needed to elucidate the early changes in the human burn wound environment. This study reports a reproducible contact burn model on human skin that explores the extent of tissue injury and healing over time, and defines the inter-individual variability in human skin to enable use in mechanistic studies on burn wound progression and healing. ⋯ This model represents an invaluable tool to evaluate the inter-individual variability in early burn wound progression and wound healing to complement current animal models and enhance the translation of preclinical research to improvements in patient care.

Previous studies about burns mortality are often exclusively based on hospital and burn centre data. National population-based reports on this topic are rather limited. The aim of this study was to analyse sex- and age-specific mortality rates of burns in Spain during the period 1979-2018. ⋯ Burns mortality rates in Spain have been decreasing during the last decades. Promotion of primary prevention measures should continue.

It had been reported that long non-coding RNA (lncRNA) H19 was associated with the proliferation of fibroblasts. However, the regulatory mechanism of H19 remains unclear. Thus, the study was designed to explore the underlying mechanism of H19 in the process of Hypertrophic scarring (HS). ⋯ Collectively, our results revealed that H19 promoted the proliferation, migration, and invasion, while impeded apoptosis of HS fibroblasts by targeting miR-3187-3p/GAB1 axis.
