The burn wound is one of the health problems in the world that affects physical and mental health. Today, adipose-derived mesenchymal stem cells (ADSCs) have received medical attention for their accessibility and the ability to reproduce and repair. The present study was designed to investigate the effect of ADSCs on burn wound healing. The present experimental study was performed on 36 male Wistar rats divided into 1 control group and 3 experimental groups. The second-degree burns with a radius of 10 mm were induced after anesthesia. ADSCs and Dulbecco's Modified Eagle Medium (DMEM) were injected into the dermis around the burn area in the ADSCs and DMEM groups, respectively. Silver sulfadiazine (SSD) ointment was applied topically once daily as the SSD group. The control group did not receive any treatment. The rats were evaluated for 21 days. Wound healing rate, histopathological parameters, and the number of fibroblasts were evaluated by the immunofluorescence technique and vascular endothelial growth factor and transforming growth factor β (TGF-β) gene expression by reverse transcription-polymerase chain reaction. The results were entered into SPSS software (SPSS Inc) and analyzed with 1-way analysis of variance and repeated measures analysis. The number of fibroblasts, the number of vessels, TGF-β, and VEGF gene expression in the burn area were significantly higher in the ADSCs group than in the SSD, DMEM, and control groups. The results also showed that the amount of inflammation was significantly lower in the ADSCs group compared with the control group (p<0.001). Moreover, the percentage of wound recovery was significantly higher in the ADSCs group compared with other groups (p<0.001). ADSCs accelerate and improve burn wound healing by affecting fibroblasts, keratinocytes, and inflammatory cells as well as increasing the expression of the TGF-β and VEGF genes, and thus increase in angiogenesis.

Background: Diabetic foot ulcers (DFU) are a prevalent complication of diabetes, leading to significant morbidity, mortality, and amputation rates. Chronic non-healing DFU often result from peripheral neuropathy, microvascular issues, and infection, with poor blood and oxygen supply being critical factors in delayed healing. The development of new treatments to promote blood supply and accelerate ulcer healing is a significant area of research for DFU management.

Skin scar formation is a critical pathological process in wound healing, but its underlying regulatory mechanisms remain incompletely elucidated. By integrating analyses of Bulk-RNA seq and single-cell RNA sequencing (scRNA-seq) data, we identified that ferroptosis-related biological processes potentially play a key role in skin scar formation. Further mechanistic studies demonstrated that in human dermal fibroblast cells, the ferroptosis regulator TIMP metallopeptidase inhibitor 1 (TIMP1) significantly promotes fibroblast differentiation toward a mature phenotype through interactions with cystatin C (CST3), characterized by upregulated expression of myofibroblast differentiation markers such as α-smooth muscle actin (α-SMA) and connective tissue growth factor (CTGF), along with enhanced cell proliferation and migration abilities.

Background: There is conflicting literature regarding mortality outcomes associated with REBOA usage in patients with severe thoracic or abdominal trauma. Our study aims to assess the benefits and negative implications of REBOA use in adult trauma patients in hemorrhagic shock with severe thoracic or abdominal injuries.
Methods: This retrospective cohort analysis utilized the American College of Surgeons Trauma Quality Improvement Program Participant Use File (ACS-TQIP-PUF) database from 2017 to 2023 to evaluate adult patients with severe isolated thoracic or abdominal trauma undergoing REBOA placement.

Background: The paper addresses an important section of pediatric combustiology - generalized meningococcal infection, associated with a severe course, the risk of disabling complications, life-threatening conditions, and high mortality.
Objective: The purpose of the study was to share the experience of treating patients with the sequelae of generalized bacterial infection caused by in a children's burn center.
Material And Methods: We conducted a retrospective analysis of the medical records of 23 patients treated in the burn department for babies from 0 to 3 years of the Children's City Clinical Hospital No.

Severe burns are a major global health concern, and are associated with long-term physical and psychological impairments, multi-organ dysfunction, and substantial morbidity and mortality. While burn injuries in adults trigger systemic immuno-metabolic alterations-characterized by white adipose tissue browning, elevated resting energy expenditure, widespread catabolism, and inflammation-these adaptive responses are considerably impaired in older adults, with molecular mechanisms behind these differences remaining largely unclear. As a key regulator of systemic metabolism, investigating the pathological role of adipose tissue (AT) postburn may reveal novel targets that could potentially improve patient outcomes.
