The aim of this study was to explore the effect and mechanism of formononetin (FMNT) in thermal-injured fibroblast proliferation, apoptosis, and oxidative stress. After thermal injury, human skin fibroblast (HSF) cells showed inhibited proliferation, migration, extracellular matrix (ECM) synthesis; and increased apoptosis, reactive oxygen species (ROS) production, and inflammation. Specifically, after thermal injury, cell viability, migration distance, and protein levels of collagen I, collagen III, α-SMA, MMP1, and MMP3 were reduced; cell apoptosis rate and TUNEL-positive cell numbers were increased; the levels of Bax and cleaved caspase-3 were elevated, while Bcl-2 level was reduced. ⋯ Additionally, the levels of the P13K/AKT/mTOR signaling-related proteins (p-P13K, p-AKT, and p-mTOR) were reduced in thermally injured HSF cells, whereas FMNT could promote p-P13K, p-AKT, and p-mTOR levels. FMNT can partially alleviate the thermal injury-induced inhibition of fibroblast proliferation and migration; FMNT also inhibited the apoptosis, ROS level, and inflammation in thermal-injured cells. The effects of FMNT may be mediated by regulating the P13K/AKT/mTOR pathway.

Approximately 120,000 children in the United States are evaluated in the emergency department annually due to burn injuries. Studies have consistently documented that pediatric burns are among the most stressful events for caregivers, resulting in a wide range of emotions, including guilt, anxiety, grief, depression, and posttraumatic stress symptoms, as well as positive psychological changes, a phenomenon known as posttraumatic growth. The present pilot study aimed to explore the prevalence of elevated perceived stress as well as posttraumatic growth among caregivers of pediatric burn patients receiving outpatient burn care and using an mHealth burn platform to administer burn treatment. ⋯ Further, approximately half of the caregiver sample reported moderate to high levels of posttraumatic growth following their child's burn injury. This pilot study clarifies the level of the perceived stress that caregivers of burn-injured children experience, particularly during the treatment phase when they are responsible for their children's outpatient burn care (e.g., dressing changes). Additionally, the results shed light on the high prevalence of moderate to high posttraumatic growth in caregivers, with a prevalence rate similar to other trauma survivors.

Burn injuries pose a significant burden on both patients and healthcare systems. Yet, costs arising from the consumption of resources by these patients are rarely examined in Canada. ⋯ Findings reveal that the total cost of the initial hospitalization, from a public hospital perspective, was $11,714,348. Our study underlines the substantial burden associated with burns and highlights the need for long-term cost evaluations.

To evaluate the efficacy of therapeutic interventions on pediatric burn patients' height, weight, body composition, and muscle strength. ⋯ Each of the interventions had a positive effect on height, weight, body composition, or muscle strength. The decision to initiate an intervention should be made on a case-by-case basis following careful consideration of the benefits and risks. In future research, it is important to evaluate the heterogeneity of intervention effects and whether participation in an intervention allowed pediatric burn patients to reach the physical and functional status of healthy peers.
