Changes in fluconazole pharmacokinetics can impact on antifungal effectiveness in critically ill burn patients: a Pharmacokinetic-Pharmacodynamic (PK/PD) approach.

OBJECTIVES: The Fluconazole pharmacokinetic-pharmacodynamic relationship was investigated in a few clinical settings and only limited studies regarding burned patients are available. Thus, the authors aimed to investigate fluconazole pharmacokinetics changes and its impact on antifungal therapy coverage against dose-dependent Candida spp. applying the PK/PD approach in critically ill severely burned patients. METHODS: Fluconazole was administered as a one-hour intravenous infusion of 200 mg q12h. Doses were increased according to the coverage based on the PK/PD approach. Blood samples were collected at the end of the infusion (1st hour), two hours after (3rd hour), and before the next dose (12th or 24th hour). Serum concentrations were obtained by HPLC-UV. Pharmacokinetic parameters were estimated by noncompartmental analysis and compared with data described in healthy subjects. The effectiveness predictive index was based on the AUCss0-24h/MIC ratio, with a target above 25. RESULTS: Every pharmacokinetic parameter was reduced throughout all three sets of the study. Compared to healthy subjects, the volume of distribution was decreased about 3‒7 times, biological half-life was 2‒3 times shorter and total body clearance was slightly altered but statistically significant. Both half-life and total body clearance were correlated to the volume of distribution. Consequently, an increase in fluconazole daily dose was necessary to improve empiric coverage. CONCLUSIONS: Fluconazole pharmacokinetics is altered in critically ill severely burned patients, mainly related to the volume of distribution. Doses higher than usual may be necessary to reach the PK/PD target and guarantee antifungal coverage against dose-dependent Candida spp. up to MIC 32 mg/L.

Awareness of Burn First Aid Management among Undergraduate Medical Students at a Medical College Teaching Hospital.

Background First aid training, educational degree of health sector employee is linked to greater levels of knowledge, awareness and positive outcome in burn injury and its management but studies have shown insufficient level of awareness with unsatisfactory skills not only among professional healthcare workers but also in medical students. Objective To assess the knowledge and confidence of our medical students towards basic burn first aid and management. Method Cross sectional observational study was done using a structured, self-reported 16 multiple choice questionnaire with total marks of 30. Students was graded accordingly: more than 25 points: good, 16-25 points: satisfactory and less than 16 points: poor level of awareness about burn first aid management. Confidence in management of burn related victims, information on receiving of prior formal training in burns and sources of knowledge in students were also evaluated. Result Only a satisfactory level of awareness is seen in medical students 62.1%, 98.2% had not received any kind of formal training and the medical college curriculum was the main source of information (69.2%) followed by journals (47.1%) and internet (26%). 78.4% students felt that the curriculum provided to them was inadequate and only 5.3% students were confident in managing burn first aid. Conclusion There was inadequacy in the knowledge of burn first aid amongst undergraduate students therefore clinical course in managing burns into the undergraduate curriculum is vital.

Assessing the Feasibility of Using Parents' Social Media Conversations to Inform Burn First Aid Interventions: Mixed Methods Study.

BACKGROUND: Burns are common childhood injuries, which can lead to serious physical and psychological outcomes. Appropriate first aid is essential in managing the pain and severity of these injuries; hence, parents who need timely access to such information often seek it from the web. In particular, social media allow them to reach other parents, hence these conversations may provide insight to aid the design and evaluation of burn first aid interventions for parents. OBJECTIVE: This study aims to determine the feasibility of finding, accessing, and analyzing parent burn first aid conversations on social media to inform intervention research. METHODS: The initial choice of the relevant social media was made based on the results of a parent focus group and survey. We considered Facebook (Meta Platforms, Inc), Mumsnet (Mumsnet Limited), Netmums (Aufeminin Group), Twitter (subsequently rebranded as "X"; X Corp), Reddit (Reddit, Inc), and YouTube (Google LLC). To locate the relevant data on these platforms, we collated a taxonomy of search terms and designed a search strategy. A combination of natural language processing and manual inspection was used to filter out irrelevant data. The remaining data were analyzed manually to determine the length of conversations, the number of participants, the purpose of the initial post (eg, asking for or offering advice), burn types, and distribution of relevant keywords. RESULTS: Facebook parenting groups were not accessed due to privacy, and public influencer pages yielded scant data. No relevant data were found on Reddit. Data were collected from Mumsnet, Netmums, YouTube, and Twitter. The amount of available data varied across these platforms and through time. Sunburn was identified as a topic across all 4 platforms. Conversations on the parenting forums Mumsnet and Netmums were started predominantly to seek advice (112/116, 96.6% and 25/25, 100%, respectively). Conversely, YouTube and Twitter were used mainly to provide advice (362/328, 94.8% and 126/197, 64%, respectively). Contact burns and sunburn were the most frequent burn types discussed on Mumsnet (30/94, 32% and 23/94, 25%, respectively) and Netmums (2/25, 8% and 14/26, 56%, respectively). CONCLUSIONS: This study provides a suite of bespoke search strategies, tailored to a range of social media platforms, for the extraction and analysis of burn first aid conversation data. Our methodology provides a template for other topics not readily accessible via a specific search term or hashtag. YouTube and Twitter show potential utility in measuring advice offered before and after interventions and extending the reach of messaging. Mumsnet and Netmums present the best opportunity for informing burn first aid intervention design via an in-depth qualitative investigation into parents' knowledge, attitudes, and behaviors.

Application of Problem-Based Learning Combined with Micro-Video Teaching in Burn Surgery and Its Impact on Satisfaction with Teaching.

OBJECTIVE: This article aimed to ascertain the application of problem-based learning (PBL) combined with micro-video teaching in burn surgery teaching and its impact on satisfaction with teaching. METHODS: Fifty clinical medical students who were interns at our hospital from November 2022 to October 2023 were selected as the study subjects and randomly separated into the control group (n = 25) and the observation group (n = 25). The control group adopted traditional teaching methods. The observation group employed PBL combined with micro-video teaching mode. The scores of theory tests and skill tests, the critical thinking capability, the students' evaluation of teaching methods, the scores of teachers for teaching methods, and the scores of interns for teaching satisfaction were compared. RESULTS: The observation group possessed higher scores on theory tests and skill tests, greater critical thinking ability after teaching, higher evaluation of teaching methods and more satisfaction with their internships versus the control group (all p < 0.05). CONCLUSION: The application of PBL combined with micro-video teaching in the teaching of burn surgery can improve students' thinking ability and their satisfaction with teaching.

Plasma-derived extracellular vesicles (EVs) as biomarkers of sepsis in burn patients via label-free Raman spectroscopy.

Sepsis following burn trauma is a global complication with high mortality, with ∼60% of burn patient deaths resulting from infectious complications. Diagnosing sepsis is complicated by confounding clinical manifestations of the burn injury, and current biomarkers lack the sensitivity and specificity required for prompt treatment. There is a strong rationale to assess circulating extracellular vesicles (EVs) from patient liquid biopsy as sepsis biomarkers due to their release by pathogens from bacterial biofilms and roles in the subsequent immune response. This study applies Raman spectroscopy to patient plasma-derived EVs for rapid, sensitive, and specific detection of sepsis in burn patients, achieving 97.5% sensitivity and 90.0% specificity. Furthermore, spectral differences between septic and non-septic burn patient EVs could be traced to specific glycoconjugates of bacterial strains associated with sepsis morbidity. This work illustrates the potential application of EVs as biomarkers in clinical burn trauma care and establishes Raman analysis as a fast, label-free method to specifically identify features of bacterial EVs relevant to infection amongst the host background.

Suppression of overactivated immunity in the early stage is the key to improve the prognosis in severe burns.

Background: Severe burns can lead to systemic inflammatory response syndrome (SIRS) and multiple organ dysfunction syndrome (MODS) due to inflammation-immunity dysregulation. This study aimed to identify key immune-related molecules and potential drugs for immune regulation in severe burn treatment. Method: Microarray datasets GSE77791 and GSE37069 were analyzed to identify immune-related differentially expressed genes (DEGs), enriched pathways and prognosis-related genes. The DGIdb database was used to identify potentially clinically relevant small molecular drugs for hub DEGs. Hub DEGs were validated by total RNA from clinical blood samples through qPCR. The efficacy of drug candidates was tested in a severe burn mouse model. Pathologic staining was used to observe organ damage. Enzyme Linked Immunosorbent Assay (ELISA) was used to detect the serum IL-1b, IL-6, TNF-a and MCP-1 contents. Activation of the NF-κB inflammatory pathway was detected by western blotting. Transcriptome sequencing was used to observe inflammatory-immune responses in the lung. Results: A total of 113 immune-related DEGs were identified, and the presence of immune overactivation was confirmed in severe burns. S100A8 was not only significantly upregulated and identified to be prognosis-related among the hub DEGs but also exhibited an increasing trend in clinical blood samples. Methotrexate, which targets S100A8, as predicted by the DGIdb, significantly reduces transcription level of S100A8 and inflammatory cytokine content in blood, organ damage (lungs, liver, spleen, and kidneys) and mortality in severely burned mice when combined with fluid resuscitation. The inflammatory-immune response was suppressed in the lungs. Conclusion: S100A8 with high transcription level in blood is a potential biomarker for poor severe burn prognosis. It suggested that methotrexate has a potential application in severe burn immunotherapy. Besides, it should be emphasized that fluid resuscitation is necessary for the function of methotrexate.

Human breast milk isolated lactic acid bacteria: antimicrobial and immunomodulatory activity on the Galleria mellonella burn wound model.

Introduction: Managing burn injuries is a challenge in healthcare. Due to the alarming increase in antibiotic resistance, new prophylactic and therapeutic strategies are being sought. This study aimed to evaluate the potential of live Lactic Acid Bacteria for managing burn infections, using Galleria mellonella larvae as an alternative preclinical animal model and comparing the outcomes with a common antibiotic. Methods: The antimicrobial activity of LAB isolated from human breast milk was assessed in vitro against Pseudomonas aeruginosa ATCC 27853. Additionally, the immunomodulatory effects of LAB were evaluated in vivo using the G. mellonella burn wound infection model. Results and discussion: In vitro results demonstrated the antimicrobial activity of Lactic Acid Bacteria against P. aeruginosa. In vivo results show that their prophylactic treatment improves, statistically significant, larval survival and modulates the expression of immunity-related genes, Gallerimycin and Relish/NF-κB, strain-dependently. These findings lay the foundation and suggest a promising alternative for burn wound prevention and management, reducing the risk of antibiotic resistance, enhancing immune modulation, and validating the potential G. mellonella as a skin burn wound model.

Burn Injuries in the Pediatric Population - The Experience of a Single Center Over a Period of Two Years.

Introduction: The study investigated the therapeutic approach and clinical management of pediatric burn patients admitted to the Pediatric Surgery and Orthopedics Clinic of the County Emergency Hospital Craiova over a two-year period (2017-2018). The primary objective was to evaluate the effectiveness of the treatments applied, including grafting procedures and their impact on long-term prognosis. Material and Methods: The cases of 80 children with burns of varying severity were retrospectively analyzed. Patients were classified according to the severity and the mechanism of burn injury. The collected data were processed using Microsoft Excel 2021. Patients were classified into three categories based on the affected body surface area (BSA): Category 1 patients, with a BSA = 10%, showed very good results and required less intensive care. Category 2 patients, with a BSA between 10% and 50%, had good outcomes but needed more prolonged care. Category 3 patients, with a BSA = 50%, had satisfactory results but faced more challenges in recovery, highlighting the need for enhanced prevention measures and better treatment protocols. Results: The majority of patients came from rural areas, and thermal burns were the most common. The effectiveness and safety of the treatments applied were highlighted, with a generally favorable impact on long-term prognosis. Treatment included both surgical and non-surgical approaches, with generally favourable clinical outcomes. Conclusion: The study highlights significant differences between rural and urban environments, suggesting the need for prevention and education campaigns regarding pediatric burns and improved access to medical services. It also emphasizes the need for integrated management to reduce the severity and complications associated with burns. The results provide a solid foundation for future strategies aimed at improving the care of paediatric burn patients.

Exosomes and microRNAs: insights into their roles in thermal-induced skin injury, wound healing and scarring.

A burn is a type of injury to the skin or other tissues caused by heat, chemicals, electricity, sunlight, or radiation. Burn injuries have been proven to have the potential for long-term detrimental effects on the human body. The conventional therapeutic approaches are not able to effectively and easily heal these burn wounds completely. The main potential drawbacks of these treatments include hypertrophic scarring, contracture, infection, necrosis, allergic reactions, prolonged healing times, and unsatisfactory cosmetic results. The existence of these drawbacks and limitations in current treatment approaches necessitates the need to search for and develop better, more efficient therapies. The regenerative potential of microRNAs (miRNAs) and the exosomal miRNAs derived from various cell types, especially stem cells, offer advantages that outweigh traditional burn wound healing treatment procedures. The use of multiple types of stem cells is gaining interest due to their improved healing efficiency for various applications. Stem cells have several key distinguishing characteristics, including the ability to promote more effective and rapid healing of burn wounds, reduced inflammation levels at the wound site, and less scar tissue formation and fibrosis. In this review, we have discussed the stages of wound healing, the role of exosomes and miRNAs in improving thermal-induced wounds, and the impact of miRNAs in preventing the formation of hypertrophic scars. Research studies, pre-clinical and clinical, on the use of different cell-derived exosomal miRNAs and miRNAs for the treatment of thermal burns have been documented from the year 2000 up to the current time. Studies show that the use of different cell-derived exosomal miRNAs and miRNAs can improve the healing of burn wounds. The migration of exosomal miRNAs to the site of a wound leads to inhibition of apoptosis, induction of autophagy, re-epithelialization, granulation, regeneration of skin appendages, and angiogenesis. In conclusion, this study underscores the importance of integrating miRNA and exosome research into treatment strategies for burn injuries, paving the way for novel therapeutic approaches that could significantly improve patient outcomes and recovery times.

Crocin-1 laden thermosensitive chitosan-based hydrogel with smart anti-inflammatory performance for severe full-thickness burn wound therapeutics.

Burns are the fourth most common type of civilian trauma worldwide, and the management of severe irregular scald wounds remains a significant challenge. Herein, crocin-1 laden hydroxybutyl chitosan (CRO-HBC) thermosensitive hydrogel with smart anti-inflammatory performance was developed for accelerating full-thickness burn healing. The injectable and shape adaptability of the CRO-HBC gel make it a promising candidate for effectively filling scald wounds with irregular shapes, while simultaneously providing protection against external pathogens. The CRO-HBC gel network formed by hydrophobic interactions exhibited an initial burst release of crocin-1, followed by a gradual and sustained release over time. The excessive release of ROS and pro-inflammatory cytokines should be effectively regulated in the early stage of wound healing. The controlled release of crocin-1 from the CRO-HBC gel adequately addresses this requirement for wound healing. The CRO-HBC hydrogel also exhibited an excellent biocompatibility, an appropriate biodegradability, keratinocyte migration facilitation properties, and a reactive oxygen species scavenging capability. The composite CRO-HBC hydrogel intelligently mitigated inflammatory responses, promoted angiogenesis, and exhibited a commendable efficacy for tissue regeneration in a full-thickness scalding model. Overall, this innovative temperature-sensitive CRO-HBC injectable hydrogel dressing with smart anti-inflammatory performance has enormous potential for managing severe scald wounds.

Photothermal enhanced antibacterial chitosan-based polydopamine composite hydrogel for hemostasis and burn wound repairing.

Bleeding and bacterial infection are common problems associated with wound treatment, while effective blood clotting and vessel regeneration promotion are the primary considerations to design the wound dressing materials. This research presents a chitosan-based hydrogel with grafted quaternary ammonium and polyphosphate (QCSP hydrogel) as the antibacterial hemostatic dressing to achieve burn wound treatment. The tissue adhesion of the hydrogel sealed the blood flow and the polyphosphate grafted to the chitosan promoted the activation of coagulation factor V to enhance the hemostasis. At the same time, the grafted quaternary ammonium enhanced the antibacterial ability of the biodegradable hydrogel wound dressing. In addition, the polydopamine as a photothermal agent was composited into the hydrogel to enhance the antibacterial and reactive oxygen scavenging performance. The in vivo hemostasis experiment proved the polyphosphate enhanced the coagulation property. Moreover, this photothermal property of the composite hydrogel enhanced the burn wound repairing rate combined with the NIR stimulus. As a result, this hydrogel could have potential application in clinic as dressing material for hemostasis and infection prone would repairing.

Experimenting with Pig-based Skin Model for Burns. Testing of Mean Literature Findings.

Introduction: Animal models that closely mimic human burn wound healing processes are essential for developing effective burn wound treatments. Pigs are useful animal models for studying burn wound healing. From their extensive literature review, Andrews and Cuttle (2017) reported mean temperature and exposure time values. This study was done to provide initial burn depth for another experiment comparing two burn wound treatments. The secondary goal was to validate a systematic review on porcine burn model standardization. Material and Methods: Six four-week-old Large White x Landrace gilts were housed in a closed structure for 10 days to acclimatize. The procedures were performed under general anesthesia. A round 2.5 cm copper plate welded to an aluminum rod with a wooden handle caused the injuries. The burning device was used to reach a contact temperature of 110 C on the pig's skin. The objective was to create a superficial partial thickness (SPT) burn for 10 seconds (Group 10s) and a deep partial thickness (DPT) burn for 20 seconds (Group 20s) using a plate heated at 110ºC. No stabilizer or pressure controller was used. Wounds were conclusively dressed and harvested 24 hours later. The usual hematoxylin-eosin protocol was used to cut and stain 4-micron sections. Results: A significant difference (p 0.01) was observed in dermis involvement, with a mean of 85.61 % (95% CI= 80.62 to 90.61) for group 10s and 123.71% (95% CI= 114.91 to 132.50) for group 20s. An exposure time of 20 seconds increased dermis depth-related total collagen denaturation by almost 50% compared to 10 seconds. Conclusions: In conclusion, our experiment produced DPT burns in 10 seconds and FT burns in 20 seconds without a pressure application device.

Frailty as a sequela of burn injury: a post hoc analysis of the "RE-ENERGIZE" multicenter randomized-controlled trial and the National Health Interview Survey.

BACKGROUND: With advancements in burn treatment and intensive care leading to decreased mortality rates, a growing cohort of burn survivors is emerging. These individuals may be susceptible to frailty, characterized by reduced physiological reserve and increased vulnerability to stressors commonly associated with aging, which significantly complicates their recovery process. To date, no study has investigated burns as a potential risk factor for frailty. This study aimed to determine the short-term prevalence of frailty among burn survivors' months after injury and compare it with that of the general population. METHODS: A post hoc analysis was conducted on the Randomized Trial of Enteral Glutamine to Minimize the Effects of Burn Injury (RE-ENERGIZE) trial, an international randomized-controlled trial involving 1200 burn injury patients with partial- or full-thickness burns. Participants who did not complete the 36-Item Short Form Health Survey (SF-36) questionnaire were excluded. Data for the general population were obtained from the 2022 National Health Interview Survey (NHIS). Frailty was assessed using the FRAIL (Fatigue, Resistance, Ambulation, Illness, Loss of weight) scale. Due to lack of data on loss of weight, for the purposes of this study, malnutrition was used as the fifth variable. Illness and malnutrition were based on admission data, while fatigue, resistance, and ambulation were determined from post-discharge responses to the SF-36. The burn cohort and general population groups were matched using propensity score matching and compared in terms of frailty status. Within the burn group, patients were divided into different subgroups based on their frailty status, and the differences in their (instrumental) activities of daily living (iADL and ADL) were compared. A multivariable analysis was performed within the burn cohort to identify factors predisposing to frailty as well as compromised iADL and ADL. RESULTS: Out of the 1200 burn patients involved in the study, 600 completed the required questionnaires [follow-up time: (5.5 ± 2.3) months] and were matched to 1200 adults from the general population in the U.S. In comparison to the general population, burn patients exhibited a significantly higher likelihood of being pre-frail (42.3% vs. 19.8%, P < 0.0001), or frail (13.0% vs. 1.0%, P < 0.0001). When focusing on specific components, burn patients were more prone to experiencing fatigue (25.8% vs. 13.5%, P < 0.0001), limited resistance (34.0% vs. 2.7%, P < 0.0001), and restricted ambulation (41.8% vs. 3.8%, P < 0.0001). Conversely, the incidence rate of illness was observed to be higher in the general population (1.2% vs. 2.8%, P = 0.03), while no significant difference was detected regarding malnutrition (2.3% vs. 2.6%, P = 0.75). Furthermore, in comparison with robust burn patients, it was significantly more likely for pre-frail and frail patients to disclose compromise in ADL and iADL. The frail cohort reported the most pronounced limitation. CONCLUSIONS: Our findings suggest a higher incidence of post-discharge frailty among burn survivors in the short-term following injury. Burn survivors experience compromised fatigue, resistance, and ambulation, while rates of illness and malnutrition were lower or unchanged, respectively. These results underscore the critical need for early identification of frailty after a burn injury, with timely and comprehensive involvement of a multidisciplinary team including burn and pain specialists, community physicians, physiotherapists, nutritionists, and social workers. This collaborative effort can ensure holistic care to address and mitigate frailty in this patient population.

Effects of a nurse-led aftercare telehealth programme on sleep and psychological outcomes of adult burn survivors: A randomized controlled trial.

INTRODUCTION: Burn survivors often experience a plethora of post-burn residual needs following their discharge including psychological issues and poor sleep. These needs are often overlooked with a significant focus on resolving physical issues. Aftercare support is particularly limited. The emergence of the Coronavirus pandemic worsened the situation as burn survivors were unable to return to utilise available services outpatient basis. Thus, an innovative nurse-led aftercare programme was developed and delivered via WeChat social medial platform. The current study sought to examine the effects of the intervention on anxiety, depression, and sleep pattern among adult burn survivors. METHODS: This is a randomised controlled trial. Sixty adult burn survivors were randomly assigned to intervention and control groups. Participants in the intervention group received the nurse-led aftercare programme which involved pre-discharge support and active follow-up on WeChat over an 8-week period and an additional 4 weeks to examine the sustained effects of the intervention. Data were collected at three timepoints: baseline (T0), post-intervention (T1), and follow-up (T2). Generalised estimating equation was employed to ascertain the group, time, and interaction effects. RESULTS: Using Bonferroni corrected p value (0.017), Anxiety and depression improved at T1 and sustained at T2 with mean scores demonstrating a reduction in both variables and total score. No statistically significant improvement was however observed regarding sleep. CONCLUSION: Continuous, comprehensive support is required by burn survivors following discharge to improve psychological outcomes. Delivering aftercare via WeChat should be considered a feasible option to supporting burn survivors following discharge.

Expanding horizons in burn care: a new paradigm for General Surgeons in Brazil.

The role of the burn surgeon in Burn Treatment Centers (BTCs) is crucial for complementing the multidisciplinary approach in the treatment of burn patients. Globally, the areas of General Surgery and Plastic Surgery are the primary surgical specialties dedicated to this function. The structuring of the Burn Patient Care Line in Minas Gerais highlighted the need to expand the "Burn Care" Field of Expertise, extending it to General Surgery. With the inevitable expansion of the Care Line, pioneered by the state of Minas Gerais, to the federal level, the need for specialized surgical training encompasses both the state context and anticipates the national scenario in the short term. Therefore, the expansion of the "Burn Care" Field of Expertise is fundamental to meeting specific demands and improving the quality of care offered to burn patients, in accordance with international standarts.

Design and Evaluation of Microemulsion-Based Drug Delivery Systems for Biofilm-Based Infection in Burns.

Normal skin is the first line of defense in the human body. A burn injury makes the skin susceptible to bacterial infection, thereby delaying wound healing and ultimately leading to sepsis. The chances of biofilm formation are high in burn wounds due to the presence of avascular necrotic tissue. The most common pathogen to cause burn infection and biofilm is Pseudomonas aeruginosa. The purpose of this study was to create a microemulsion (ME) formulation for topical application to treat bacterial burn infection. In the present study, tea tree oil was used as the oil phase, Tween 80 and transcutol were used as surfactants, and water served as the aqueous phase. Pseudo ternary phase diagrams were used to determine the design space. The ranges of components as suggested by the design were chosen, optimization of the microemulsion was performed, and in vitro drug release was assessed. Based on the characterization studies performed, it was found that the microemulsion were formulated properly, and the particle size obtained was within the desired microemulsion range of 10 to 300 nm. The I release study showed that the microemulsion followed an immediate release profile. The formulation was further tested based on its ability to inhibit biofilm formation and bacterial growth. The prepared microemulsion was capable of inhibiting biofilm formation.

[Research progress on the application of artificial intelligence in the early diagnosis and treatment of burn diseases].

Artificial intelligence (AI) technology is advancing rapidly, constantly presenting its application value and broad prospects in the medical field. Especially in the early intervention of burn diseases, the new developments, applications, and challenges of AI technology have a significant impact on the clinical outcomes of burn patients. Based on this, this article reviews the concept, classification, learning style, and application of AI in the early diagnosis and treatment of burn diseases, with a focus on discussing the challenges and suggestions of the application of AI technology in the medical field, in order to provide reference and suggestions for the better application of AI in the early diagnosis and treatment of burn diseases.

Advancements in cell-based therapies for thermal burn wounds: a comprehensive systematic review of clinical trials outcomes.

BACKGROUND: Burn trauma is one of the major causes of morbidity and mortality worldwide. The standard management of burn wounds consists of early debridement, dressing changes, surgical management, and split-thickness skin autografts (STSGs). However, there are limitations for the standard management that inclines us to find alternative treatment approaches, such as innovative cell-based therapies. We aimed to systematically review the different aspects of cell-based treatment approaches for burn wounds in clinical trials. METHODS: A systematic search through PubMed, Medline, Embase, and Cochrane Library databases was carried out using a combination of keywords, including "Cell transplantation", "Fibroblast", "Keratinocyte", "Melanocyte", or "Stem Cell" with "Burn", "Burn wound", or "Burn injury". Firstly, titles and abstracts of the studies existing in these databases until "February 2024" were screened. Then, the selected studies were read thoroughly, and considering the inclusion and exclusion criteria, final articles were included in this systematic review. Moreover, a manual search was performed through the reference lists of the included studies to minimize the risk of missing reports. RESULTS: Overall, 30 clinical trials with 970 patients were included in our study. Considering the type of cells, six studies used keratinocytes, nine used fibroblasts, eight used combined keratinocytes and fibroblasts, one study used combined keratinocytes and melanocytes, five used combined keratinocytes and fibroblasts and melanocytes, and one study used mesenchymal stem cells (MSCs). Evaluation of the preparation type in these studies showed that cultured method was used in 25 trials, and non-cultured method in 5 trials. Also, the graft type of 17 trials was allogeneic, and of 13 other trials was autologous. CONCLUSIONS: Our study showed that employing cell-based therapies for the treatment of burn wounds have significant results in clinical studies and are promising approaches that can be considered as alternative treatments in many cases. However, choosing appropriate cell-based treatment for each burn wound is essential and depends on the situation of each patient.

PROTECTIVE EFFECT OF A NEW SUPEROXIDE-PRODUCING ENZYME COMPLEX FROM RASPBERRY IN RATS WITH THIRD-DEGREE THERMAL BURNS.

Thermal burns are the most common type of burn injuries. Medical treatment for burns is crucial, especially for third-degree burns and when a significant surface area of the body is affected. One of the most pressing issues in modern medicine is the search for new effective means to accelerate the healing of burn wounds. Oxygen radicals play a significant role in maintaining homeostasis, forming the body's resistance to infection, and ensuring the regeneration of organs and tissues. In this study, a superoxide (O2-)-producing enzyme (SPE) from raspberries was applied (topically to the skin, injected under the wound surface, with solution concentrations of 12.75% and 5%) after a third-degree thermal burn to determine its reparative effects on the skin. To assess the condition of the animals that had suffered burn injuries and the healing process, blood parameters were analyzed, and cytogenetic indices of bone marrow from the femur of the animals were studied: mitotic index, number of polyploid cells, and chromosomal aberrations. When analyzing hematological, cytogenetic, and histological parameters, significant differences were found between the «clean burn¼ groups and the groups in which SPE was used in different concentrations and methods of application. The use of SPE in both concentrations contributed to a reduction in the area of burn wounds compared to a «clean burn¼. The survival rate of animals for 30 days (before the end of the experiment) was 100% when using a 12.75% SPE solution and 50% when using a 5% SPE solution. The use of SPE led to significant differences in hematological parameters from the «clean burn¼ group throughout the entire duration of the experiment, showing a tendency to normalize the parameters. Under the influence of the 12.75% SPE solution, there was a tendency toward normalization of the mitotic index, along with a significant reduction in the percentage of polyploid cells and chromosomal aberrations, which may indicate its beneficial effects. This study found that a 12.75% SPE solution derived from raspberries was more effective and had healing properties on third-degree thermal burns, promoting rapid healing of the burn wound.

Hydrogel-Based Dressings and Multidisciplinary Care in Severe Pediatric Burns: A Case Report of Successful Healing and Hypertrophic Scar Prevention.

BACKGROUND Pediatric burn injuries are a global health concern, particularly in infants and toddlers, who face increased risks owing to their higher water content. Despite substantial medical treatment, the mortality rates remain challenging, especially in severe cases. This study explored non-surgical interventions for pediatric burn injuries, aiming to enhance care and alleviate the burden on affected children. CASE REPORT A 16-month-old boy with 30% mixed second- and third-degree burns presented with a scald injury. Initial measures included dressing and analgesia. The Plastic Surgery team led the treatment. Upon admission, the patient experienced convulsions due to hyponatremia in the burn unit and was subsequently transferred to the Pediatric Intensive Care Unit (PICU). Burn care management included the use of hyaluronic acid and occupational therapy. Scheduled dressing changes, including the use of glycerin-based dressings, resulted in satisfactory wound healing. Split skin grafting from the right thigh was performed to prevent elbow joint contracture. Preventive measures against hypertrophic scarring were also implemented. The patient was discharged after follow-up appointments. Consent for publication of case details and photographs was obtained from the patient's father. CONCLUSIONS The presented non-surgical approach, incorporating hyaluronic acid, Bactigras, Elasto-Gel, and a multidisciplinary team, can effectively treat mixed partial- and full-thickness burn injuries in pediatric populations. Split-thickness grafts may be required in functional areas. Therefore, a comprehensive management strategy that considers tissue damage, electrolyte balance, and infection is crucial. This report underscores the importance of meticulous assessment and correction of overall patient condition, especially in pediatric cases of electrolyte imbalance.
