Whether burn injury affects boys and men differently is currently unknown. To test the hypothesis that burned boys have lower exercise capacity and exercise training-induced responses compared with burned men, 40 young boys (12 ± 4 years, 149 ± 20 cm, 46 ± 18 kg) were matched to 35 adult men (33 ± 9 years, 174 ± 10 cm, 84 ± 16 kg) based on extent of burn injury (total body surface area burned, boys 46 ± 14% vs men 47 ± 30, P = .85) and length of hospital stay (boys 33 ± 23 vs men 41 ± 32 days, P = .23). Strength (peak torque) and cardiorespiratory fitness (peak VO2) were normalized to kg of lean body mass for group comparisons. ⋯ Boys strength were 13-15 per cent lower than men at discharge and after RET (main effect for group, P < .0001). Cardiorespiratory fitness improved to a greater extent in men (19%) compared with boys (10%) after the RET (group × time interaction, P = .011). These results show that at discharge and after RET, burn injury may have age-dependent effects and should be considered when evaluating efficacy and progress of the exercise program.

Mafenide acetate is an effective but costly antimicrobial solution used for burn wounds. The package insert instructs the user to discard unused solution within 48 hours of opening. The purpose of this study is to evaluate the antimicrobial activity of mafenide acetate beyond 48 hours after reconstitution, to possibly reduce cost by eliminating product waste. ⋯ This in vitro study demonstrates that the antimicrobial activity of mafenide acetate remains present for at least 60 days after reconstitution. Unused mafenide may not need to be discarded at 48 hours after opening. Reducing wasted product has the potential to translate into cost savings.

The intrinsic relationship between fluid volume and open wound size (%) has not been previously examined. Therefore, we conducted this study to investigate whether open wound size can be predicted from fluid volume plus other significant factors over time and to evaluate how machine learning may perform in predicting open wound size. This retrospective study involved patients with at least 20% TBSA burned. ⋯ Bland-Altman analysis showed that there were no biases in the models. Open wound size can be predicted reliably using machine learning and fluid volume, days since admission, TBSA burned, and age. Future work will be needed to validate the utility of this study's models in a clinical environment.

Recent evidence indicates that increased frailty is associated with increased mortality in patients with burn over the age of 65 years. However, the effect of frailty may not be restricted to those over the age of 65 years. We hypothesize that admission frailty is associated with mortality in patients with burn ≥50 years of age. ⋯ Multivariate logistic regression revealed that increased admission FS is associated with increased mortality to a greater extent in the 50- to 65-year-old group (age 50-65 years: OR, 2.5; 95% CI, 1.4 to 4.6; age ≥ 65 years: OR, 1.63; 95% CI, 1.003 to 2.7). FS on admission allow for an improved assessment of preinjury physiological condition in patients with burn aged ≥50 years. Poor preinjury physiological fitness is associated with increased risk of death in patients with burn aged ≥50 years.

When treating burn injuries, to date, there still remains significant disagreement whether presence of hypothermia (HT) on burn centers' intensive care unit (BICU) admission improves or worsens outcomes. The presented single burn center experiences set out to further evaluate the incidence, cause, and potential effects of HT on outcomes in severely burned patients. Between January 2015 and February 2017, 142 severely burned patients were admitted to a BICU. ⋯ HT at admission remains a common problem following burn injury. Main risk factors include inappropriate temperature management after injury and during transport, extent of TBSA burn, and quantity of resuscitation. Given the high incidence, the involved health care and, especially, also prehospital providers should be further educated about existing recommendations and guidelines to prevent HT.
