Special Issue Information

Dear Colleagues,

Burn injury is a complex traumatic event with various local, regional, and systemic effects. The pathophysiology of the burn patient shows the full spectrum of the complexity of inflammatory response reactions. In the acute phase, the inflammation mechanism may have negative effects because of capillary leak, the propagation of inhalation injury, and the development of multiple organ failure. Attempts to mediate these processes remain a central subject of burn-care-related research. Conversely, inflammation is a necessary component in the later-stage processes of wound healing. Improvements in acute burn care have enabled patients to survive massive burns that would have once been fatal. Now, up to 70% of patients develop hypertrophic scars after burns. Functional and psychosocial sequelae remain a major rehabilitative challenge, decreasing patients’ quality of life and delaying their reintegration into society. Approaches to optimizing the healing potential of burn wounds use targeted wound care and surgery to minimize the development of hypertrophic scarring. Such approaches often fail, and the modulation of the established scar is continued, although the optimal indication, timing, and combination of therapies are yet to be established. The need for novel treatments is paramount, and future efforts to improve patients’ outcomes and quality of life should include the optimization of wound healing to attenuate or prevent hypertrophic scarring, well-designed trials to confirm treatment efficacy, and the further elucidation of molecular mechanisms to allow the development of new preventive and therapeutic strategies. In this Special Issue of IJMS, we are looking for articles which deliver a profound insight into the current science of burn wound pathophysiology, burn wound healing, and scarring.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Skin microbiome dysbiosis has deleterious effects, and the factors influencing burn scar formation, which affects the scar microbiome composition, are unknown. Therefore, we investigated the effects of various factors influencing scar formation on the scar microbiome composition in patients with burns. We collected samples from the burn scar center and margin of 40 patients with burns, subgrouped by factors influencing scar formation. Scar microbiome composition-influencing factors were analyzed using univariate and multivariate analyses. Skin graft, hospitalization period, intensive care unit (ICU) admission, burn degree, sex, age, total body surface area burned (TBSA), time post-injury, transepidermal water loss, the erythrocyte sedimentation rate, and C-reactive protein levels were identified as factors influencing burn scar microbiome composition. Only TBSA and ICU admission were associated with significant differences in alpha diversity. Alpha diversity significantly decreased with an increase in TBSA and was significantly lower in patients admitted to the ICU than in those not admitted to the ICU. Furthermore, we identified microorganisms associated with various explanatory variables. Our cross-sectional systems biology study confirmed that various variables influence the scar microbiome composition in patients with burns, each of which is associated with various microorganisms. Therefore, these factors should be considered during the application of skin microbiota for burn scar management. Full article
