Burn care continues to improve and larger total body surface area (TBSA) burn survival is increasing. These survivors require more extensive care than smaller burns and are at higher risk for wound/scar-related complications. Prior work has shown low rates of follow-up for burn survivors linked to socioeconomic factors such as housing insecurity and substance use. There are limited studies that evaluate socioeconomic factors that contribute to follow-up and reconstructive surgery rates in massively burned patients. Patients who survived to discharge with >50% TBSA burns and planned return to the treating institution were included in the study. Univariate and multivariate analyses were performed on the data collected. Sixty-five patients were included with an average TBSA of 63.1%. Fifty-three patients (81.5%) attended at least one follow-up appointment with median of 4 follow-up appointments. Younger patients (33 ± 9 vs 44 ± 11; P = .0006), patients with larger TBSA burns (65 ± 13 vs 55 ± 5%; P = .02), those with private insurance, and those without housing insecurity (1.8% vs 45.4%; P = .003) were more likely to follow up. On multivariate regression analysis, patients with housing insecurity were independently associated with lack of follow-up (OR: 0.009; CI: 0.00001-0.57). Thirty-five patients had at least one reconstructive surgery and 31 patients had reconstructive surgery after discharge. No patients with housing insecurity underwent reconstructive surgery. Follow-up rates in massive burns were higher than reported for smaller TBSA burns and more than half received reconstructive surgery. Housing-insecure patients should be targeted for improved follow-up and access to reconstructive surgery.

Adequate and effective pain management and prevention of depression are essential in patients with burns. This study aims to explore the effects of ketamine sedation in patients with burns in terms of mood disorders, depression, anxiety, and suicidality during postoperative follow-up in the intensive care unit. This study targeted subjects aged 18-65 years, in the ASA I-II class, with basic communication skills, no history of diagnosed mental illness, and no history of neuropsychiatric or cognitive disorders or related treatment. The study was conducted on 67 patients. After preoxygenation, anesthesia induction was practiced with 2 mg/kg intravenous (IV) propofol and 1 mcg/kg IV fentanyl in the general anesthesia group. Anesthesia was continued with a mixture of 0.3-0.5 mcg/kg/min remifentanil, 2% sevoflurane, 50% air, and 50% oxygen. In the sedation group, 1 mcg/kg IV fentanyl and 1 mg/kg IV ketamine were administered at induction; anesthesia was maintained by adding 30-50 mg IV propofol if necessary. The Montgomery-Asberg Depression Rating Scale (MADRS), Hamilton Anxiety Rating Scale (HAM-A), and Beck Scale for Suicidal Ideation (BSSI) have been administered via way of means of a psychiatrist preoperatively and on the primary postoperative day. In intragroup evaluations, MADRS values for the sedation anesthesia group decreased statistically significantly after the anesthesia (11.63 ± 5.49) compared to the preanesthesia period (14.44 ± 7.22) (P < .001). HAM-A scores of both anesthesia groups decreased statistically significantly after anesthesia. No patient was found to have suicidal ideation in all evaluations in which BSSI was used. Patients with burns may have a high potential for depression, anxiety disorders, and suicidal tendencies due to the trauma they have experienced. In these patients, sedation anesthesia with ketamine may reduce negative mood, depression, anxiety, and suicidal tendencies in the postoperative period.

This study utilized CiteSpace software to conduct a bibliometric analysis of the literature related to the use of growth hormones in treating burns. The results showed that the research on this topic has attracted increasing attention from scholars worldwide, with the number of publications increasing annually. The research teams and institutions involved in this field are mainly concentrated in China, followed by the United States, Russia, and other countries. The analysis also revealed the prominent co-cited literature and the most influential authors in the field, such as D. N. Herndon and Y. Li. The main research themes identified in the literature included the effects of growth hormones on wound healing, tissue repair and regeneration, inflammatory responses, and cell proliferation. In addition, the research on the clinical applications of growth hormone in burn treatment has been expanded to include areas such as metabolic regulation, immune function, and the prevention of infections. The findings of this study provide useful insights into the current status and future directions of research in the field of growth hormone treatment of burns.

Finding a perfect epidermal transplant remains a holy grail of burn surgery. The epidermis is a site of stem cells that allows for epithelial regeneration. The use of cultured epithelial autografts (CEA) for the treatment of major burns was first reported in 1981. CEA requires specialized skills; thus, reports from different burn centers have shown mixed results. Comparing our modern data with past data shows how this field has advanced while maintaining institutional control. We performed a retrospective analysis of all patients admitted between January 1, 1988 and December 31, 2021 for massive burns that were managed with CEA. Patients were divided into pre-defined groups: G1 (early-era) = 1988-1999, G2 (pre-modern-era) = 2000-2010, and G3 (modern-era) = 2011-2021. We compared demographics, %TBSA, presence of inhalation-injury, length of hospital stay (LOS), complications, and mortality. We treated 52 patients with CEA during the study period. In the modern-era, we found 11 patients; in the pre-modern-era, 10; and in the early-era, 31. Injury characteristics, including %TBSA and the presence of inhalation-injury, were not significantly different between the groups. We observed lower mortality rates in G1 and G3 (G1:20% vs. G2:42% vs. G3:27%, P < 0.05), although the predicted mortality was not significantly different between the groups (G1:50% vs. G2:47% vs. G3:49%, NS). Patients in G1 also had a shorter hospital LOS, in days, (G1:90 vs. G2:127 vs. G3:205, P < 0.05). Finally, the surface-area grafted per patient was the highest in G2 (G1:2,000cm2 vs. G2:4,187cm2 vs. G3:4,090cm2, P < 0.01). CEA has not gained popularity despite proven positive outcomes. Our retrospective analysis showed that CEA should be considered as a treatment option for patients with large burns, given proper training and infrastructure.

Burn reconstruction outcomes are an area of growing investigation. Although there is evidence of measured physical improvements in scar characteristics after laser treatment, there is little information on patient-reported outcomes. The purpose of this study is to compare patient-reported outcomes between burn survivors with and without laser treatment. The study included participants in the Burn Model System National Database at a single center; participants that received outpatient laser treatment for burn scars were compared to a matched group of burn survivors that did not receive laser. The following outcomes were examined: Satisfaction With Life Scale, Mental and Physical Component Summary of the Veterans Rand Survey, and the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Intensity Scale. Regression analyses examined the associations between laser treatment and each outcome at 12 and 24 months. The study population included 287 adult burn survivors (65 laser group and 222 control group). The significant differences found between the 2 groups included: burn size (laser: 14.9, 13.5 SD, control: 8.9, 11.1 SD; P < .001), insurance type (P = .036), inhalation injury (laser: 17.2%, control: 2.7%; P < .001), and ventilator requirement (laser: 27.7%, control: 13.5%; P = .013). Laser treatment was not associated with any of the outcomes at both follow-up time points. Further research is needed to develop patient-reported outcome measures that are more sensitive to the clinical changes experienced by burn survivors receiving laser treatment.

It has long been known that T cells participate in wound healing; however, the landscape of the signaling derived from T cells in the process of wound healing is still enigmatic. With the advantages of scRNA-seq, in combination with immunofluorescent imaging, we identified activated T cells, cytotoxic T cells (CTLs), exhausting T cells, and Tregs existing in the inflammation phase of wound healing. Further analysis revealed each T cell population possess distinguished signals contributed to wound healing, some are critical for improving the wound healing quality. Besides, this study discovered and validated the existence of exhausting T cells among the T cells accumulated in the skin during wound healing, and the molecular mechanism(s) and contribution of exhausting T cells to wound healing deserve extensive studies in the future.

Pediatric burn injuries are a leading cause of morbidity with infections being the most common acute complication. Thermal injuries elicit a heightened cytokine response while suppressing immune function; however, the mechanisms leading to this dysfunction are still unknown. Our aim was to identify extracellular proteins and circulating phosphoprotein expression in the plasma after burn injury to predict the development of nosocomial infection (NI). Plasma was collected within 72 hours after injury from 64 pediatric burn subjects; of these, 18 went on to develop an NI. Extracellular damage-associated molecular proteins, FAS(APO), and protein kinase b (AKT) signaling phosphoproteins were analyzed. Subjects who went on to develop an NI had elevated high-mobility group box 1, heat shock protein 90 (HSP90), and FAS expression than those who did not develop an NI after injury (NoNI). Concurrently, phosphorylated (p-)AKT and mammalian target of rapamycin (p-mTOR) were elevated in those subjects who went on to develop an NI. Quadratic discriminant analysis revealed distinct differential profiles between NI and NoNI burn subjects using HSP90, FAS, and p-mTOR. The area under the receiver-operator characteristic curves displayed significant ability to distinguish between these 2 burn subject cohorts. These findings provide insight into predicting the signaling proteins involved in the development of NI in pediatric burn patients. Further, these proteins show promise as a diagnostic tool for pediatric burn patients at risk of developing infection while additional investigation may lead to potential therapeutics to prevent NI.

Autologous skin cell suspension (ASCS) is an adjunct to conventional split-thickness skin grafts (STSG) for acute burns, enhancing healing and reducing donor site requirements. This study validates ASCS's predictive benefits in hospital stay reduction and cost savings by analyzing outcomes and real-world charges post-ASCS implementation at a single institution. A retrospective study (2018-2022) included burn patients with ≥10% TBSA. The study population comprised 2 groups: burns treated either with a combination of ASCS ± STSG or with STSG alone. Outcomes included LOS, surgeries, infection, complications, days on antibiotics, and adjusted charge per TBSA. The ASCS ± STSG group demonstrated significantly shorter LOS (Mdn: 16.0 days, IQR: 10-26) than the STSG group (Mdn: 20.0 days, IQR: 14-36; P = .017), and fewer surgeries (Mdn: 1.0, IQR: 1-2) versus the STSG group (Mdn: 1.0, IQR: 1-4; P = .020). Postoperative complications were significantly lower in ASCS ± STSG (11% vs. 36%; P < .001). The STSG group had a longer distribution of antibiotic days (IQR: 0-7.0, min-max: 0-76) than the ASCS ± STSG group (IQR: 0-0, min-max: 0-37; P = .014). Wound infection incidence did not differ (P = .843). ASCS ± STSG showed a lower distribution of adjusted charge per TBSA (IQR: $10 788.5-$28 332.6) compared to the STSG group (IQR: $12 336.8-$29 507.3; P = .602) with a lower mean adjusted charge per TBSA ($20 995.0 vs. $24 882.3), although this was not statistically significant. ASCS ± STSG utilization demonstrated significant reductions in LOS, surgeries, postoperative complications, antibiotics, and potential cost savings. These findings underscore the practicality of integrating ASCS in burn management, offering substantial benefits to patients and healthcare institutions.

Considering the high consumption of and preference for traditional treatments among people and the lack of enough studies on the effectiveness of these treatments, we aimed to review articles on the use of traditional and complementary medicine, focusing on how they affect healing, debridement, and hypertrophic scars. In this study, we conducted the literature search in international databases PubMed, Google Scholar, Ovid, Scopus, Web of Science, and Cochrane Library, as well as Persian databases Scientific Information Database (SID), Magiran, Iranmedex, and IranDoc. Retrieved hits were reviewed by three authors for screening based on inclusion and exclusion criteria, and the screening process is expressed as Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework flow chart. Twenty-two studies were included. The evaluated outcomes were wound healing in 19, pain control in 5, itching in 4, and scar appearance in 2 studies. All of the studies showed equal or improved effects compared to common treatments. Aloe vera, Centella asiatica, and Arnebia euchroma were the most common plants. We revealed that traditional medicine is beneficial in burn wound treatment. The diversity in ingredients that are used in traditional medicine brings up the need for further controlled prospective studies to evaluate the precise superiority of these treatments compared to standard care.
