A critical need exists for early, accurate diagnosis of burn wound severity to help identify the course of treatment and outcome of the wound. Laser speckle imaging (LSI) is a promising blood perfusion imaging approach, but it does not account for changes in tissue optical properties that can occur with burn wounds, which are highly dynamic environments. Here, we studied optical property dynamics following burn injury and debridement and the associated impact on interpretation of LSI measurements of skin perfusion. ⋯ SFDI measurements demonstrate that optical properties change in response to burn injury in a porcine model. We then apply theoretical modeling to demonstrate that the measured range of optical property changes can affect the interpretation of LSI measurements of blood flow, but this effect is minimal for most of the measured data. Collectively, our results indicate that, even with a dynamic burn wound environment, blood-flow measurements with LSI can serve as an appropriate strategy for accurate assessment of burn severity.

Rapid diagnosis of microbes in the burn wound is a big challenge in the medical field. Traditional biochemical detection techniques take hours or days to identify the species of contaminating and drug-resistant microbes. Near-infrared spectroscopy (NIRS) is evaluated to address the need for a fast and sensitive method for the detection of bacterial contamination in liquids. ⋯ Our findings validate for the first time a novel technique aimed at the rapid, noncontacted, highly sensitive, and specific recognition of several microbial species including drug-resistant ones. This technique could represent a promising approach to identify diverse microbial species and a potential bedside device to rapidly diagnose infected wounds.

Observational Study
ABO blood group and effects on ventilatory time, length of stay and mortality in major burns a retrospective observational outcome study.
A total of 225 patients were included (2008-2019) with median TBSA of 26%; interquartile range (IQR) of 20-37%; median age 45 years (IQR 22-65 years); median Baux score (age + TBSA%); 76 (IQR 53- 97); 168 (75%) were male; median duration of hospital stay was 31 days (IQR 19-56); a total of 138 (61%) received treatment with mechanical ventilation; and 29 (13%) died. In a multivariable regression model, we were unable to isolate any significant effect of any blood group (O, A, B, AB) on the outcome measures studied (ventilatory time, LOS, and mortality). IN ⋯ contrary to many other major areas of disease in which ABO blood groups affect outcome, we were unable to find any such effect on patients with burns. Given the precision of the outcome models presented (AUC 0.93) any such an effect, if missed due to the limited study cohort, may be considered limited and to have only a minor clinical impact.

Although burns most often result in negative psychological consequences, some studies have identified self-reported, positive psychological growth after such injuries. Post-traumatic growth is a positive psychological change in which an individual develops stronger functioning, beliefs, and values following a trauma. To date, no quantitative analysis has been done of post-traumatic growth in young adult burn survivors. ⋯ Results of the hierarchical multiple regression analysis indicated that change in a family relationship after the burn experience, treatment situation, and level of interpersonal relationship skills, were statistically significant in young adult burn survivors' post-traumatic growth. Results support good interpersonal relationship skills and positive family relationships appear to facilitate the positive growth after burn experience. Clinical implications are presented in the discussion.

Patients with burn injuries cause significant healthcare economic burden, often utilising extra-hospital resources, caregiving, and specialized care. ⋯ We are the first to our knowledge to report the association of treatment outcomes and opioid dependence in patients hospitalized at the national level with a burn injury. We show that there were higher 30-day all-cause readmission rates and in-hospital resource utilization among patients with opioid-dependence.
