Renal failure is the most common organ failure in severely burned patients. However, defining acute kidney injury and renal failure is very challenging. This study was designed to determine the relationship between a biomarker commonly measured on admission, serum creatinine, and outcomes in burn patients. ⋯ Elevated creatinine on admission is associated with an increased risk of morbidity and mortality. We suggest that admission creatinine can be used as a "red flag" to identify patients at a higher risk for poor outcomes.

Physical changes to appearance caused by burn injuries can have significant psychological consequences. Medical tattooing is an intervention aimed at restoring appearance but little is known about the experiences of patients or the psychological impact of medical tattooing following burns. This study aimed to explore burn patients' psychological experiences of medical tattooing. ⋯ Medical tattooing may be a potentially valuable intervention psychologically, although support and information seem important and further research is required.

Multicenter Study
A multicenter study analyzing the association of vitamin D deficiency and replacement with infectious outcomes in patients with burn injuries.
Vitamin D (25OHD) deficiency is associated with poor outcomes in intensive care populations. The primary objective of this 7-center study was to determine if 25OHD deficiency is associated with infectious outcomes in adult burn patients. Generalized linear mixed modeling was used to control for center effect, percent total body surface area burn (% TBSA), age, and presence of inhalation injury. ⋯ Deficient patients were more likely to have an infectious outcome (52.1% vs 36.0%, p = 0.002), acute kidney injury with renal replacement therapy (p = 0.009), less ventilator free days in the first 28 days (p < 0.001), and vasopressors (p = 0.01). After controlling for center, % TBSA, age, and inhalation injury the best model also included presence of deficiency (OR 2.425 [CI 1.206-4.876]), days until 25OHD supplement initiation (OR 1.139 [CI 1.035-1.252]), and choice of cholecalciferol over ergocalciferol (OR 2.112 [CI 1.151-3.877]). To the authors' knowledge, this is the first multicenter study to evaluate the relationship between 25OHD and infectious complications in burn patients.

Patients with burns commonly present to Emergency Departments (EDs), in addition to burn centers. Patients at burn centers typically have more severe burns than those at EDs, and previous studies have analyzed burn center databases. To update the overall burn epidemiology in the United States (US), we analyzed burn injury trends and sources across all age groups using the National Electronic Injury Surveillance System (NEISS), which collects all injuries reported to US EDs. ⋯ The most common injured region was the hand for all age groups (34.44%). Although most burn injuries were potentially preventable, the overall burn rate did not decrease 2000-2018. Therefore, we offer guidance on prevention strategies for high-risk sources and age groups.

Alu elements are retrotransposons related to epigenetic modifications. To date, the role of epigenetics in hypertrophic scars from burn remains unknown. Here, our aim was to examine the pathophysiology of hypertrophic scars from an epigenetic perspective. ⋯ Alu total methylation (mC) and the uCmC pattern were significantly lower, whereas uCuC was significantly higher, in hypertrophic scar tissues than in normal skin (p < 0.0001). Receiver operating characteristic analysis indicated that the uCmC and uCuC patterns are useful as hypertrophic scar DNA methylation markers after burn, with 91.30% sensitivity and 96.23% specificity and 100% sensitivity and 94.23% specificity, respectively. Our findings suggest that epigenetic modifications play a major role in hypertrophic scar pathogenesis, and may be the starting point for developing a novel technique for burn scar treatment.
