Despite the advantages of using deceased donor skin in the treatment of burns, it is not easy to obtain these grafts due to low tissue donation rates. In order to discover the social representations of family members of organ donors regarding skin donation and to analyze the convergences and divergences of these representations between family members who consented and those who refused to allow skin to be donated for transplantation, we conducted interviews with 20 family members of organ donors in a situation of brain death. ⋯ This study shows that in the opinion of family members who consented and those who did not authorize skin donation, the consideration contains both positive and negative representations, which can have different weights and influence decision-making. This study also highlights, in an unprecedented way, the representation of the animalization of the donor, which can be a reason for the refusal to allow skin to be donated.

Keloid scars occur as a result of abnormal wound healing caused by trauma or inflammation of the skin. The progression of keloids is dependent on genetic and environmental influences. The incidence is more prevalent in people with darker skin tones (African, Asian and Hispanic origin). Studies have demonstrated that transforming growth factor (TGF) β/Smad signalling has an essential function in keloid as well as that USP11 could modulate the activation of TGFβ/Smad signalling and impact the progression of the fibrotic disease. Nonetheless, the potential mechanisms of USP11 in keloid were still unclear. The authors postulated that USP11 up-regulates and augments the ability of proliferation, invasion, migration and collagen deposition of keloid-derived fibroblasts (KFBs) through deubiquitinating TGF-β receptor II (TβRII). ⋯ USP11 elevates the ability of proliferation, collagen deposition, invasion and migration of keloid-derived fibroblasts by deubiquitinating TβRII.

To observe depressive-like behavior and hippocampus monoamine oxidase A (MAOA) changes in burned mice. ⋯ Burned mice showed "delayed" depressive-like behavior combined with a degree of anxiety; this phenomenon is likely associated with the increase in MAOA expression in the hippocampus.

Individuals who present to a hospital for treatment of a burn of any magnitude are more frequently hospitalised for ischemic heart disease, even decades after injury. Blood platelets are key mediators of cardiovascular disease. To investigate platelet involvement in post-burn cardiovascular risk, platelet reactivity was assessed in patients at 2- and 6-weeks after non-severe (TBSA < 20%) burn injury, and in a murine model 30 days after 8% TBSA full-thickness burn injury. ⋯ Platelets from burn injured mice also demonstrated increased response to collagen peptides but did not show any change in thrombosis following vascular injury. This study demonstrates the persistence of a small but significant platelet hyperreactivity following burn injury. Although our data does not suggest this heightened platelet sensitivity modulates thrombosis following vascular injury, the contribution of sub-clinical platelet hyperreactivity to accelerating atherogenesis merits further investigation.

Magnesium (Mg) is an essential factor in the healing process. This study aimed to evaluate the effect of Mg creams on healing burn wounds in the rat model. ⋯ Mg cream was effective in healing burns.
