The survival rate of patients with severe burn is positively associated with increasing the incidence of the Clostridioides difficile (C. difficile) infection (CDI). The surviving rate of severe burn patients now has an improved but the incidence of Clostridioides difficile (C. difficile) infection (CDI) has been continues increasing during recent two decades. This study assessed the molecular typing and phenotypic characterization isolates of C. difficile in burn patients with diarrhea, as well as environmental and skin infections with C. difficile spores at a referral burn hospital in Isfahan, Iran. It mainly aimed to evaluate the dominant bacterial structure in the gut microbiome of burned subjects with and without CDI. ⋯ Despite appropriate infection control strategies in the burn intensive care unit, CDI remains prevalent in severe burn patients. Eventually, the overgrowth of A. muciniphila and the decreased abundance of F. prausnitzii in burn cases with CDI could be potential predictive microbiome biomarkers in burned patients.

We examined the interactive effects of copper (Cu) and overweight (overweight) and obesity on outcomes of burn patients. We posited that higher baseline Cu among burn patients with overweight or obesity will be associated with poor clinical outcomes vs. patients with a normal weight. ⋯ Higher baseline Cu seems associated with adverse outcomes in overweight and obese burn patients. Further research is needed to confirm this association and explore the direction of causality.

Mesenchymal Stem Cells (MSCs) are known to contribute to wound healing by increasing tissue regeneration. This study examined the effect of MSC-Lyophilizate (MSC-L) on the recovery of the zone of stasis in thermal burns. ⋯ Administration of umbilical cord-derived MSC-L is of potential importance in wound healing. In our study, we observed that MSC-L that contained 1.5 million cells contributed significantly to the recovery of the stasis zone of burn.

Skin substitutes are designed dressings intended to promote wound closure. In previous in vitro and in vivo studies on small animal, an acellular skin patch made of collagen hydrogel with dermal fibroblast conditioned medium (Col-DFCM), a collagen sponge scaffold with freshly harvested skin cells (OTC), and a platelet-rich-plasma gel with freshly harvested skin cells (PRP) have been developed and tested for immediate treatment of full-thickness wound. However, to determine the safety and efficacy of these skin patches for clinical applications, further study in a large animal model is needed. ⋯ The results showed that OTC treated wound was more mature as indicated by the presence of a thinner epidermis followed by the Col-DFCM, PRP and NT group. Immunohistochemistry analysis also confirmed the integrity and maturity of the regenerated skin, with positive expression of cytokeratin 10 (CK10) and involucrin in the epidermal layer. In conclusion, Col-DFCM, OTC and PRP treatments promote healing of full-thickness wound and have the potential to be used clinically for rapid treatment of full-thickness wound.
