BACKGROUND: Burn trauma is one of the major causes of morbidity and mortality worldwide. The standard management of burn wounds consists of early debridement, dressing changes, surgical management, and split-thickness skin autografts (STSGs). However, there are limitations for the standard management that inclines us to find alternative treatment approaches, such as innovative cell-based therapies. We aimed to systematically review the different aspects of cell-based treatment approaches for burn wounds in clinical trials.
METHODS: A systematic search through PubMed, Medline, Embase, and Cochrane Library databases was carried out using a combination of keywords, including \"Cell transplantation\", \"Fibroblast\", \"Keratinocyte\", \"Melanocyte\", or \"Stem Cell\" with \"Burn\", \"Burn wound\", or \"Burn injury\". Firstly, titles and abstracts of the studies existing in these databases until \"February 2024\" were screened. Then, the selected studies were read thoroughly, and considering the inclusion and exclusion criteria, final articles were included in this systematic review. Moreover, a manual search was performed through the reference lists of the included studies to minimize the risk of missing reports.
RESULTS: Overall, 30 clinical trials with 970 patients were included in our study. Considering the type of cells, six studies used keratinocytes, nine used fibroblasts, eight used combined keratinocytes and fibroblasts, one study used combined keratinocytes and melanocytes, five used combined keratinocytes and fibroblasts and melanocytes, and one study used mesenchymal stem cells (MSCs). Evaluation of the preparation type in these studies showed that cultured method was used in 25 trials, and non-cultured method in 5 trials. Also, the graft type of 17 trials was allogeneic, and of 13 other trials was autologous.
CONCLUSIONS: Our study showed that employing cell-based therapies for the treatment of burn wounds have significant results in clinical studies and are promising approaches that can be considered as alternative treatments in many cases. However, choosing appropriate cell-based treatment for each burn wound is essential and depends on the situation of each patient.

Background. Burn is a major public health problem in pediatric populations worldwide. This study aimed to determine the survival status and predictors of mortality among pediatric burn victims admitted to burn centers in Ethiopia. Methods. A retrospective cohort study was conducted on the patient charts of 412 pediatric patients with burn injuries at burn centers in Addis Ababa from the 1st of January 2016 to the 30th of December 2019. Data was entered into the Epi-Data manager. Then, the data was exported to STATA V-14 for cleaning and analysis. For the analysis, the proportional hazard model was used. After the model fitness test, variables with a P-value of <.25 in the bivariate analysis were fitted to the multivariate analysis. Finally, statistical significance was decided at a P-value of <.05, and the hazard ratio was used to determine the strength of the association. Result. The study reported an overall incidence rate of 2.4 per 1000 child days. Additionally, it revealed that the median hospital length of stay was 25.00 days (95% CI: 21.57, 28.45). During the follow-up period, 8.25% of deaths occurred among pediatric patients with burn injuries. Specifically, having a full-thickness burn (adjusted hazard ratio [AHR] 2.51, 95% CI: 1.12, 5.62) and neck burn (AHR 2.82, 95% CI: 1.04, 7.68) were identified as significant predictors contributing to increased mortality among burn-injured pediatric individuals. Conclusion. The study highlighted significant mortality rates among pediatric patients suffering from burn injuries. Based on the findings a full-thickness burn injury and burns in the neck area are independent predictors of mortality in pediatric burn patients. Based on the identified predictors of mortality in pediatric burn patients, clinicians should prioritize early recognition, prompt intervention, multidisciplinary management, vigilant monitoring, and preventive strategies to optimize outcomes and reduce mortality rates in this vulnerable population.

Epithelial damage leads to early reactive oxygen species (ROS) signaling, which regulates sensory neuron regeneration and tissue repair. How the initial type of tissue injury influences early damage signaling and regenerative growth of sensory axons remains unclear. Previously we reported that thermal injury triggers distinct early tissue responses in larval zebrafish. Here, we found that thermal but not mechanical injury impairs sensory axon regeneration and function. Real-time imaging revealed an immediate tissue response to thermal injury characterized by the rapid Arp2/3-dependent migration of keratinocytes, which was associated with tissue scale ROS production and sustained sensory axon damage. Isotonic treatment was sufficient to limit keratinocyte movement, spatially restrict ROS production, and rescue sensory neuron function. These results suggest that early keratinocyte dynamics regulate the spatial and temporal pattern of long-term signaling in the wound microenvironment during tissue repair.

Following burn injury, patients are at increased risk of infection and are often cited as having a high incidence of difficult-to-treat pathogens (DTp). The purpose of this study is to determine the incidence of DTp after burn injury, which factors are associated with their development, and subsequent outcomes. This single-center, retrospective study assessed patients with thermal or inhalation injury who had a positive culture resulting in initiation of treatment (i.e., excision, topical, or systemic antimicrobials). Demographic data, pathogen and resistance profiles, and prior exposure to topical and systemic antimicrobials were collected. Pathogens were considered DTp if they were multi-drug-resistant (MDR), extensively drug-resistant (XDR), methicillin-resistant Staphylococcus aureus (MRSA), extended-spectrum beta-lactamase (ESBL)-producing, AmpC-producing, carbapenem-resistant, difficult-to-treat resistance (DTR) Pseudomonas sp., carbapenem-resistant Acinetobacter baumannii (CRAB), or Stenotrophomonas spp. Sixty-five patients who grew 376 pathogens were included in the final analysis. Two-hundred thirteen (56.7%) pathogens were considered DTp. Prior exposure to 7 of the 11 collected topical antimicrobials and 9 of 11 systemic antimicrobial classes were significantly associated with future development of a DTp. This remained true for six and eight, respectively, after controlling for significant covariates via logistic regression. As there were only four deaths, a Cox-proportional hazard analysis was not feasible. The Kaplan-Meier plot according to DTp revealed a clear divergence in mortality (Log rank p = 0.0583). In this analysis, exposure to topical and systemic antibiotics was associated with the development of DTp. The results from this pilot study will inform the next iteration of multicenter study.

Background: Heat burns are a prevalent type of trauma. Rapid and effective treatment is crucial for deep burns to minimize complications. Autologous skin grafting is a highly effective treatment for full-thickness burns. A multidisciplinary team plays a vital role in managing burn patients undergoing skin grafting, from initial contact to outpatient follow-up. Case Summary: This case study involves a 56-year-old patient who suffered burns on 60% of his body following an alcohol explosion on an open flame. The patient underwent autologous skin grafting at a Major Burn Center. Initial symptoms included severe pain and immobility, but the patient remained alert and breathed spontaneously. The diagnosis was a loss of epidermis and dermis with burns covering 60-69% of the total body surface area (TBSA) and third-degree burns covering 10% TBSA. Post-discharge, the patient showed significant improvement, with complete healing of the grafts and partial resolution of other lesions. Six months after the intervention, the patient significantly improved his autonomy and mobility. Conclusions: This case highlights the importance of burn prevention and the critical role of multidisciplinary teams in the entire care pathway of burn patients. Appropriate diagnosis, complete treatment, and continuous multidisciplinary support are essential to prevent complications and ensure recovery.

UNASSIGNED: Burn injury inevitably leads to changes in the endogenous production of cytokines, as well as adrenal and gonadal steroids. Previous studies have reported gender-related differences in outcome following burn injury, which suggests that gonadal steroids may play a role. The aim of this study was to assess alterations in concentration of endogenous steroids in patients with burn injury.
UNASSIGNED: For this single-center, prospective descriptive study, high-sensitivity liquid chromatography tandem mass spectrometry (LC-MS/MS)-based steroid quantification was used to determine longitudinal profiles of the concentrations of endogenous steroids in plasma from sixteen adult male patients with burn injury (14.5-72% of total body surface area). Steroids were extracted from plasma samples and analyzed using multiple reaction monitoring acquisition, with electrospray ionization on a triple quadruple mass spectrometer. Total protein concentration was measured in the samples using spectrophotometry.
UNASSIGNED: Steroid and total protein concentration distributions were compared to reference intervals characteristic of healthy adult men. Concentrations of the following steroids in plasma of burn injured patients were found to correlate positively to the area of the burn injury: cortisol (r = 0.84), corticosterone (r = 0.73), 11-deoxycortisol (r = 0.72), androstenedione (r = 0.72), 17OH-progesterone (r = 0.68), 17OH-pregnenolone (r = 0.64) and pregnenolone (r = 0.77). Concentrations of testosterone decreased during the acute phase and were up to ten-times lower than reference values for healthy adult men, while concentrations of estrone were elevated. By day 21 after injury, testosterone concentrations were increased in younger, but not older, patients. The highest concentrations of estrone were observed on day 3 after the injury and then declined by day 21 to concentrations comparable to those observed on the day of the injury.
UNASSIGNED: Burn injury alters endogenous steroid biosynthesis, with decreased testosterone concentrations and elevated estrone concentrations, during the first 21 days after the injury. Concentrations of glucocorticoids, progestagens and androgen precursors correlated positively with the area of burn injury. The finding of increased estrone following burn injury needs to be confirmed in a larger hypothesis-driven study.

BACKGROUND: Appearance concerns are common following burns. However, there is a lack of research investigating early psychological interventions for appearance concerns. This qualitative study explored the acceptability of early psychological interventions for appearance concerns after burns.
METHODS: Fifteen adults (nine female; 18-56 years) with appearance concerns were interviewed within three months post-burn to explore their views about the acceptability of early psychological interventions for these concerns. Interviews were audio-recorded and transcribed. Template analysis informed data collection and analysis.
RESULTS: Three themes represented participants\' views about the acceptability of early psychological interventions for appearance concerns: (1) early psychological interventions are absent; (2) early psychological interventions are acceptable within a therapeutic relationship (to manage upsetting emotions and thoughts about appearance, with therapists who are experienced in supporting burns patients); and (3) ambivalence and obstacles exist (e.g., difficulties accepting help, minimising injuries or concerns, and time restrictions following hospital discharge).
CONCLUSIONS: Early psychological interventions for appearance concerns following burns are likely to be acceptable for some patients. However, ambivalence and potential barriers remain to be addressed. Embedding early psychological interventions for appearance concerns into routine burn care could increase acceptability through normalisation.

BACKGROUND: Early retrospective data identify that dysphagia is common in older persons with burn injury, suggesting a rate of 47 %, and that it is associated with medical, burn, and nutritional outcomes.
OBJECTIVE: To prospectively (1) explore the incidence, (2) describe associations, and (3) evaluate risk factors for dysphagia in patients ≥ 75 years old hospitalised with burn injury.
METHODS: All patients > 75 years old admitted to Concord-Repatriation-General-Hospital with burn injury over 4 years (2019-2023) were assessed for dysphagia on presentation and were continually monitored throughout their admission. Burn injury, demographic, and nutritional data were prospectively captured and analysed for association with dysphagia.
RESULTS: Sixty-two patients (33 male) aged 75-95 years (median=83 years) were recruited. Dysphagia was identified in 50 %. Dysphagia was associated with burn size (p = 0.002), pre-existing cognitive impairment (p = 0.000), hospital length of stay (p = 0.001), in-hospital complications (p = 0.000), feeding dependence (p = 0.002), nutritional status (p = 0.013) and enteral feeding duration (p = 0.030). Cognitive impairment was the most sensitive predictor for dysphagia at 100 % (specificity=29 %, NPV=100 %, PPV=59 %). Development of secondary comorbidities was less sensitive at 52 % (NPV 65 %), but was associated with high specificity (90 %) and PPV (84 %).
CONCLUSIONS: One in every two patients ≥ 75 years admitted with burn injury will demonstrate dysphagia during their hospital admission. Those with pre-existing cognitive impairment are most at risk.
