Versatility in the use of cadaveric skin grafts for wound management.

BACKGROUND: Cadaveric skin grafts were initially used for the management of acute burn wounds. The biological coverage of the wound improves the quality of the wound bed, which prepares it to receive an autologous skin graft. The benefits of cadaveric skin graft in burn wounds have led to its use in the management of acute and chronic wounds of diverse etiologies. OBJECTIVE: To evaluate the use of cadaveric skin graft and subsequent autologous split-thickness skin graft (STSG) in the management of wounds of diverse etiologies at a single institution. MATERIALS AND METHODS: A retrospective analysis was performed of patients with wounds of different etiologies managed with cadaveric skin grafts followed by a second procedure in which autologous STSG was performed from May 2017 through May 2022 in the Plastic and Reconstructive Surgery Department of German Hospital, Buenos Aires, Argentina. RESULTS: A total of 25 patients with wounds of different etiologies were included. The mean affected body surface area (BSA) was 1.87%. The mean engraftment percentage of the cadaveric skin graft was 96.6%. The mean engraftment percentage of the STSG was 90.6%. All patients demonstrated improvement in local edema and inflammation, reduced secretions, and reduced pain after treatment. Two patients (8%) had complications, with 1 case of delayed healing of the donor site and 1 case of hypertrophic scarring. CONCLUSIONS: Cadaveric skin graft with subsequent STSG is a simple, safe, and effective alternative for the management of complex wounds of diverse etiologies. This technique is particularly useful in patients with multiple comorbidities who are at risk of recurrence and of developing multiple wounds during their lifetime.

Evaluation of the efficacy, safety and satisfaction rates of platelet-rich plasma, non-cross-linked hyaluronic acid and the combination of platelet-rich plasma and non-cross-linked hyaluronic acid in patients with burn scars treated with fractional CO2 laser: A randomized controlled clinical trial.

Skin scarring can result from burns, injuries, stretch marks and acne, leading to cosmetic and functional difficulties. Treatments for burn scars encompass a range of options, such as lasers, corticosteroid injections, surgery and regenerative techniques such as platelet-rich plasma (PRP). Hyaluronic acid-based products offer skin hydration and shield against aging effects. A study is being conducted to evaluate how effective PRP injection, hyaluronic acid and their combination improve burn scars and their effects on quality of life and potential disabilities. In our study, PRP and non-cross-linked hyaluronic acid treatments were compared in 10 individuals with burn scars between 2022 and 2023. Patients received CO2 fractional laser treatment followed by injections in scar areas. Evaluations included the Vancouver scar scale (VSS), biometric assessments, ultrasounds and satisfaction ratings. Two therapy sessions were conducted at 1-month interval, and assessments were done before treatment, 1 month after the first session, and 3 months after the first session. Biometric assessments showed significant improvements in various parameters (tewametry, corneometry, erythema index, melanin index, cutometry, thickness and density) in the intervention groups compared to the placebo group (p <0.05). PRP-non-cross-linked hyaluronic acid, PRP and non-cross-linked hyaluronic acid treatments exhibited the best clinical responses with significant differences between groups (p <0.05). Dermal thickness did not show significant improvement during treatment sessions, and changes among subjects were not significantly different. The colorimetry parameter improved in all groups except the placebo group, with no significant difference between intervention groups. The VSS significantly decreased in all treatment groups except the placebo group. PRP, non-cross-linked hyaluronic acid and especially the combination of these two treatment options are very effective in treating burn scars.

A systematic review of procedural treatments for burn scars in children: Evaluating efficacy, safety, standard protocols, average sessions and tolerability based on clinical studies.

Managing burn scars in children presents significant challenges. This study investigates effective treatment methods for burn scars, focusing on efficacy, safety, standard protocols and tolerability. Major databases such as PubMed, Scopus and Web of Science were thoroughly searched up to August 2024, emphasizing procedural treatments for burn scars in children. Key data collected included participant demographics, sample sizes, intervention methods, follow-up protocols, treatment effectiveness and reported adverse events. A total of 256 children were assessed, with all procedural treatments yielding satisfactory outcomes. Among the various methods, trapeze-flap plasty and percutaneous collagen induction showed improvements in all patients. In the laser treatment group, which included 161 children, the Vancouver Scar Scale (VSS) score reduction ranged from 55.55% to 76.31%, with outcomes rated as good (24.61%) to excellent (60%). Laser treatment using local anaesthesia proved to be well tolerated by children. Our findings indicate that various methods-including trapeze-flap plasty, percutaneous collagen induction, phototherapy and fractional CO2 laser-demonstrate a relatively good response and an acceptable safety profile. Notably, light-based therapies/lasers may serve as safe, effective and tolerable options for scar treatment in this age group, often eliminating the need for general anaesthesia.

Music therapy with adult burn patients in the intensive care unit: short-term analysis of electrophysiological signals during music-assisted relaxation.

Burn patients often face elevated pain, anxiety, and depression levels. Music therapy adds to integrative care in burn patients, but research including electrophysiological measures is limited. This study reports electrophysiological signals analysis during Music-Assisted Relaxation (MAR) with burn patients in the Intensive Care Unit (ICU). This study is a sub-analysis of an ongoing trial of music therapy with burn patients in the ICU. Electroencephalogram (EEG), electrocardiogram (ECG), and electromyogram (EMG) were recorded during MAR with nine burn patients. Additionally, background pain levels (VAS) and anxiety and depression levels (HADS) were assessed. EEG oscillation power showed statistically significant changes in the delta (p < 0.05), theta (p = 0.01), beta (p < 0.05), and alpha (p = 0.05) bands during music therapy. Heart rate variability tachograms high-frequencies increased (p = 0.014), and low-frequencies decreased (p = 0.046). Facial EMG mean frequency decreased (p = 0.01). VAS and HADS scores decreased - 0.76 (p = 0.4) and - 3.375 points (p = 0.37) respectively. Our results indicate parasympathetic system activity, attention shifts, reduced muscle tone, and a relaxed state of mind during MAR. This hints at potential mechanisms of music therapy but needs to be confirmed in larger studies. Electrophysiological changes during music therapy highlight its clinical relevance as a complementary treatment for ICU burn patients.Trial registration: Clinicaltrials.gov (NCT04571255).

Exosomes in nanomedicine: a promising cell-free therapeutic intervention in burn wounds.

Burn injuries are serious injuries that have a big impact on a person's health and can even cause death. Incurring severe burns can incite an immune response and inflammation within the body, alongside metabolic changes. It is of utmost importance to grasp the fact that the effects of the burn injury extend beyond the body, affecting the mind and overall well-being. Burn injuries cause long-lasting changes that need to be taken care of in order to improve their quality of life. The intricate process of skin regeneration at the site of a burn wound involves a complex and dynamic interplay among diverse cells, growth factors, nerves, and blood vessels. Exciting opportunities have arisen in the field of stem cells and regenerative medicine, allowing us to explore the development of cell-free-based alternatives that can aid in the treatment of burn injuries. These cell-free-based therapies have emerged as a promising facet within regenerative medicine. Exosomes, also referred to as naturally occurring nanoparticles, are small endosome-derived vesicles that facilitate the delivery of molecular cargo between the cells, thus allowing intercellular communication. The knowledge gained in this field has continued to support their therapeutic potential, particularly in the domains of wound healing and tissue regeneration. Notably, exosomes derived from mesenchymal stem cells (MSCs) can be safely administered in the system, which is then adeptly uptaken and internalized by fibroblasts/epithelial cells, subsequently accelerating essential processes such as migration, proliferation, and collagen synthesis. Furthermore, exosomes released by immune cells, specifically macrophages, possess the capability to modulate inflammation and effectively diminish it in adjacent cells. Exosomes also act as carriers when integrated with a scaffold, leading to scarless healing of cutaneous wounds. This comprehensive review examines the role of exosomes in burn wound healing and their potential utility in regeneration and repair.

The impact of an open-label design on human amniotic membranes vs. silver sulfadiazine dressings for second-degree burns: a randomized controlled clinical trial.

BACKGROUND: Burn wounds require optimal medical management due to associated psycho-emotional and socioeconomic impacts and severe pain. The use of synthetic and biological dressings improves healing and reduces burn wound complications. The present study aimed to compare the outcomes of using human amniotic membrane (hAM) dressings and conventional silver sulfadiazine (SSDZ) ointment dressings in the management of second-degree burn wounds. METHODS: Fifty patients who participated in this clinical trial were divided into two groups via simple randomization. All the enrolled patients, who had burnt in the last 24 h, had thermal damage mechanisms and were suffering from less than 20% second-degree heat-burn wounds on the skin surface. The target group (n = 25) was treated with hAM, and the control group (n = 25) was treated with SSDZ ointment. The researcher-designed checklist was used to determine the clinical performance in the follow-up assessments on days 7, 14, and 30. RESULTS: No significant differences were detected in terms of sex, age, or percentage of burn wounds (p > 0.05). Wound epithelialization at days 7, 14, and 30, scar formation, wound pigmentation, pain severity, analgesia requirements, and hospital stay length (on day 30) were significantly lower in the target group (treated with hAM) than in the control group (treated with SSDZ ointment) (p < 0.05). However, treatment costs in the target group ($170) were significantly higher than those in the control group ($71) (p < 0.001). CONCLUSION: Despite its higher cost, hAM, as a technology-based therapy dressing, demonstrates superiority over SSDZ ointment in terms of wound healing and pain management.

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.

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.

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.

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.

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.

Photo-Crosslinked Pro-Angiogenic Hydrogel Dressing for Wound Healing.

Severe burns are one of the most devastating injuries, in which sustained inflammation and ischemia often delay the healing process. Pro-angiogenic growth factors such as vascular endothelial growth factor (VEGF) have been widely studied for promoting wound healing. However, the short half-life and instability of VEGF limit its clinical applications. In this study, we develop a photo-crosslinked hydrogel wound dressing from methacrylate hyaluronic acid (MeHA) bonded with a pro-angiogenic prominin-1-binding peptide (PR1P). The materials were extruded in wound bed and in situ formed a wound dressing via exposure to short-time ultraviolet radiation. The study shows that the PR1P-bonded hydrogel significantly improves VEGF recruitment, tubular formation, and cell migration in vitro. Swelling, Scanning Electron Microscope, and mechanical tests indicate the peptide does not affect the overall mechanical and physical properties of the hydrogels. For in vivo studies, the PR1P-bonded hydrogel dressing enhances neovascularization and accelerates wound closure in both deep second-degree burn and full-thickness excisional wound models. The Western blot assay shows such benefits can be related to the activation of the VEGF-Akt signaling pathway. These results suggest this photo-crosslinked hydrogel dressing efficiently promotes VEGF recruitment and angiogenesis in skin regeneration, indicating its potential for clinical applications in wound healing.

[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.

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.

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.

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.

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.

Comparison of the effect of chewing gum with routine method on ileus after burns: a randomized clinical trial.

BACKGROUND: Chewing gum is a healthy, cheap, and familiar solution for patients with premature irritation of the stomach and intestines. This study compared the effect of chewing gum and the routine method on ileus after burns. METHODS: This study is a randomized clinical trial conducted in Valiasr Hospital in Arak, Markazi Province, in the center of Iran, from December 2021 to February 2023. After the diagnosis of intestinal ileus in 83 patients hospitalized in the burn department by a general surgeon, with the available sampling method, these patients were evaluated based on the inclusion and exclusion criteria of the study. As a result, 66 patients were selected and divided into groups A (33 patients in the intervention group: routine care + gum chewing) and B (33 patients in the control group: routine care) by random allocation method. For the intervention group, from entering the ward until the beginning of oral feeding, gum (without sugar) was chewed four times a day for 15 min, while control groups received the routine diet of the department. Both groups' condition of the bowel sounds, time of passing gas, and stool were recorded. The statistical analyses were performed using SPSS version 16. The chi-squared, Fisher's exact, Independent t-test, and Mann-Whitney U tests were utilized. RESULTS: The results showed that the median bowel sound return time, time of the first gas discharge, earliest defecation time, and time to start the diet were significantly shorter in the intervention group than in the control group (P < 0.001). CONCLUSION: This study showed the effect of chewing gum without sugar in shortening the symptoms of intestinal ileus after burns. However, it was not effective in reducing the hospitalization period of patients. According to these results, it is recommended to add chewing gum to the routine care of people hospitalized due to burns.
