Neutrophil extracellular traps (NETs) have a dual role in the innate immune response to thermal injuries. NETs provide an early line of defence against infection. However, excessive NETosis can mediate the pathogenesis of immunothrombosis, disseminated intravascular coagulation (DIC) and multiple organ failure (MOF) in sepsis. Recent studies suggest that high interleukin-8 (IL-8) levels in intensive care unit (ICU) patients significantly contribute to excessive NET generation. This study aimed to determine whether IL-8 also mediates NET generation in patients with severe thermal injuries. IL-8 levels were measured in serum samples from thermally injured patients with ≥15% of the total body surface area (TBSA) and healthy controls (HC). Ex vivo NET generation was also investigated by treating isolated neutrophils with serum from thermal injured patients or normal serum with and without IL-8 and anti-IL-8 antibodies. IL-8 levels were significantly increased compared to HC on days 3 and 5 (p < 0.05) following thermal injury. IL-8 levels were also significantly increased at day 5 in septic versus non-septic patients (p < 0.001). IL-8 levels were also increased in patients who developed sepsis compared to HC at days 3, 5 and 7 (p < 0.001), day 10 (p < 0.05) and days 12 and 14 (p < 0.01). Serum containing either low, medium or high levels of IL-8 was shown to induce ex vivo NETosis in an IL-8-dependent manner. Furthermore, the inhibition of DNase activity in serum increased the NET-inducing activity of IL-8 in vitro by preventing NET degradation. IL-8 is a major contributor to NET formation in severe thermal injury and is increased in patients who develop sepsis. We confirmed that DNase is an important regulator of NET degradation but also a potential confounder within assays that measure serum-induced ex vivo NETosis.

BACKGROUND: There is no standardized practice in pediatric pain assessment with burn injuries in the outpatient clinic setting.
OBJECTIVE: This review aims to identify reliable, validated tools to measure pain in the pediatric burn clinic population.
METHODS: The literature search for this integrative review was conducted using the databases of PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Cochrane, and Embase from 2011 to 2023. Quality and relevance were appraised using the Johns Hopkins Nursing Evidence-Based Practice Model. Reporting was done according to a Preferred Reporting Items for Systemic Reviews and Meta-Analysis checklist.
RESULTS: Fourteen articles and two clinical practice guidelines met inclusion criteria and were included in this review.
CONCLUSIONS: The Pain Observation Scale for Young Children and the COMFORT Behavior Scale tools have shown good reliability and construct validity and can be safely used to measure background and procedural pain in daily burn practice. Further research on reliable, validated pain assessment techniques in the pediatric burn population is needed.

UNASSIGNED: Burn injuries lead to dysregulation of immune molecules, impacting cellular and humoral immune pathways. This study aims to determine the prediction of immune molecule activity during burn wound healing among elderly patients.
UNASSIGNED: The current study utilized the Gene Expression Omnibus (GEO) database to extract the proper gene set. Also, the literature review was conducted in the present study to find immune signatures. The study used the \"enrich r\" website to identify the biological functions of extracted genes. The critical gene modules related to mortality were identified using the weighted gene co-expression network analysis (WGCNA) R package.
UNASSIGNED: The appreciated GSE was extracted. According to the data, the most upregulated signatures were related to natural killer (NK) cells, and the most downregulated signatures were associated with M1 macrophages. Also, the results of WGCNA have shown that the most related gene modules (P<107 and score 0.17) to mortality were investigated, and the modules 100 first genes were extracted. Additionally, the enrich r analysis has demonstrated related pathways, including the immune process, including regulation of histamine secreted from mast cell (P<0.05), T helper 17 cell differentiation (P<0.05), and autophagy (P<0.05) were obtained. Finally, by network analysis, the critical gene \"B3GNT5\" were obtained (degree>ten and \"betweenness and centrality\">30 were considered).
UNASSIGNED: The study identified significant changes in macrophage and NK cell expression patterns post-burn injury, linking them to potential improvements in clinical outcomes and wound healing. The gene B3GNT5, associated with mortality, was highlighted as a key marker for prognostic evaluation.

UNASSIGNED: Burns are a prevalent form of unintentional injury and a significant public health concern in developing countries. We aimed to investigate the epidemiological and clinical characteristics of adult burn patients at a major center in Eastern China.
UNASSIGNED: This 6-year retrospective study analyzed patients with varying degrees of burns between January 2017 and December 2022 at the Suzhou Burns and Trauma Center. The study extracted demographic, clinical, and epidemiological data from electronic medical records for analysis.
UNASSIGNED: The study included 3,258 adult patients, of which 64.3% were male. The largest age group affected 30-59-year-old adults (63.04%). Scalds were the leading cause of burns (1,346, 41.31%), followed by flames (1,271, 39.01%). The majority of burn hospitalizations were those with moderate burns (1791, 54.97%). The morbidity rate was low at 0.68%, while mortality was strongly associated with age, etiology, and total body surface area. Patients with certain types of burns, such as explosions, hot crush injuries, and electric burns had more operations, longer lengths of hospital stay, and higher costs compared to those with scalds and flame injuries.
UNASSIGNED: Different prevention strategies should be formulated according to different etiologies, ages, and genders.

Although our understanding of frailty has evolved and multiple indices have been developed, the impact of burn injuries on long-term health has been overlooked. With over 11 million annual cases globally, burns affect all demographics, although socioeconomic disparities are evident. With survival rates improved, morbidity among survivors is becoming more evident, and shows similarity to predictors of frailty. Some of the chronic effects of burns, including mental health issues and increased risks of disease, mirror frailty markers. Studies show burn survivors have lower life expectancy, independent of burn severity. Integrating burn history into frailty assessments and establishing specialized long-term care can mitigate this frailty risk. Improved interdisciplinary follow-up and research are vital for enhancing burn survivors\' quality of life and longevity.

For over five decades, many experimental and clinical studies have shown predominantly positive but controversial results on the efficacy of hyperbaric oxygen (HBO2) therapy in burns. The study aimed to define a common denominator or constellations, respectively, linked to the effects of HBO2 in burns with a special focus on dosage parameters. Based on original work since 1965, species, number of individuals, type of study, percentage of total body surface area (TBSA), region, depth of burn, causative agent, interval between burn and first HBO2 session, pressure, duration of individual session, number of HBO2 sessions per day, cumulative number of HBO2 sessions and type of chamber were assessed. Out of 47 publications included, 32 were animal trials, four were trials in human volunteers, and 11 were clinical studies. They contained 94 experiments whose features were processed for statistical evaluation. 64 (67.4%) showed a positive outcome, 16 (17.9%) an ambiguous one, and 14 (14.7%) a negative outcome. The only factor independently influencing the results was pressure with ATA (atmospheres absolute) lower than 3 ATA being significantly associated with better outcomes (p=0.0005). There is a dire need for well-designed clinical studies in burn centers equipped with hyperbaric facilities to establish dedicated treatment protocols.

BACKGROUND: Patients with severe burn injuries are at risk of venous thromboembolism (VTE) and associated sequelae. Burn-injured patients may require larger doses of VTE prophylaxis so underdosing may occur with standard regimens. Monitoring anti-factor Xa (AFXa) levels may allow tailoring of dosage but is currently uncommon. The purpose of this systematic review was to methodically review the available literature with respect to AFXa in severe burn-injured patients, and thereby assess its efficacy.
METHODS: Using PRISMA guidelines, \"Xa\" and \"burns\" were used to systematically review MEDLINE (1946 - present) and EMBASE (1974 - present) databases for publications regarding the monitoring of AFXa levels for thromboprophylaxis in burn-injured patients.
RESULTS: Eight studies (432 patients) met inclusion. Peak AFXa level at initial measurement was reported in all studies and was within the range for prophylaxis in 184 of 432 cases (42.6%), below range in 246 of 432 cases (56.9%) and above range for 2/432 (0.5%). Complications were reported in 7 studies (412 patients), with a total of 30 (7.3%) complications, comprising of 16 (53.3%) VTE events and 14 (46.7%) mortalities. Three studies comprising 270 patients compared complications between patients who were within the reference range with patients who were below the range. There were 164 patients from the \'within the reference range\' groups that had a total of 6 (3.7%) complications, comprised of 4 (66.7%) VTE events and 2 (33.3%) mortalities. There were 106 patients from the \'below reference range group\' that had a total of 11 (10.4%) complications, comprised of 9 (81.8%) VTE events and 2 (18.2%) mortalities.
CONCLUSIONS: Our findings suggest standard prophylactic anticoagulation dosing risks underdosing and therefore, an increased risk in the development of VTE. AFXa monitoring allows individually tailored dose adjustment to reach therapeutic levels, which may be efficacious in reducing VTE events and is therefore recommended where possible.

BACKGROUND: Nosocomial infections contribute significantly to mortality and morbidity in burn patients. Selective decontamination of the digestive tract is an infection prevention measure that has been shown to improve survival in mechanically ventilated intensive care unit (ICU) patients. It has been hypothesized that burn patients may benefit from selective decontamination of the digestive tract.
METHODS: We will conduct a systematic review with meta-analysis and trial sequential analysis of randomized clinical trials (RCTs) assessing the patient-important effects of selective decontamination of the digestive tract in burn patients, as compared with placebo or no intervention/standard of care. The primary outcome will be 30-day mortality. Secondary outcomes include serious adverse events, anti-microbial resistance, pneumonia, blood stream infections, ICU- and hospital-free days and 90-day mortality. We will search the following databases: CENTRAL, MEDLINE, EMBASE, BIOSIS, Web of Science and CINAHL and follow the recommendations provided by the Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The certainty of evidence will be assessed according to the GRADE approach: Grading of Recommendations Assessment, Development and Evaluation.
CONCLUSIONS: There is clinical equipoise about the use of selective decontamination of the digestive tract in burn patients. In the outlined systematic review and meta-analysis, we will assess the desirable and undesirable effects of selective decontamination of the digestive tract in burn patients.

Genital burns are unique and complex injuries that impact patients physically and emotionally. This study investigates the specific impact of genital burns on psychosocial and physical outcomes. A retrospective cohort study was conducted using the TriNetX database, encompassing over 117 million patients from U.S. healthcare institutions. Patients with genital burns were identified and categorized into sub-cohorts based on TBSA and burn degree. Propensity score matching and cohort balancing were performed based on age, gender, race, and ethnicity. Outcomes were analyzed both short-term (1 month) and long-term (5 years), focusing on psychiatric and physical aspects. This study identified 3,496 genital burn patients over a 15-year period. Analyses revealed that genital burns significantly increased short-term risk of death (RR: 2.8), anxiety (RR: 2.656), hospitalization (RR: 2.167), and any anxiety, PTSD, or depression (RR: 2.363), and long-term risk of death (RR: 1.658) and pruritus (RR: 1.58) (all p<0.05). Interestingly, genital burn patients showed a lower risk of chronic joint pain compared to other burn injuries (RR: 0.815) (p<0.05). These results occurred independently of the extent of TBSA. Genital burns have a distinctive impact on patients, leading to higher rates of certain psychiatric morbidities and physical complications. This study highlights the need for tailored care and consideration of the unique challenges faced by patients with genital burns, both in the immediate aftermath and in the long term. Understanding the specific impacts of genital burns is vital for healthcare practitioners to develop care strategies and better support for patients recovering from such injuries.

Shewanella putrefaciens is an opportunistic pathogen rarely responsible for human infection. However, it has been reported that it causes skin and soft tissue infections and bacteremia in immune-compromised patients, such as cellulitis, abscesses, bacteremia, and wound infection. It is an oxidase and catalase-positive non-fermenter gram-negative rod that produces hydrogen sulfide. We report the case of a 90-year-old woman, who presented an invasive infectious burn wound associated with Shewanella putrefaciens bacteremia. She was admitted into the burn center of the military hospital M.S Nekkache of Algiers, suffering from 40% TBSA with a history of diabetes. After one week of admission, the patient complained of a high fever. Microbiological culture of the catheter tip was positive and showed pale colonies on the MacConkey agar, non-lactose fermenting plate. Nutritive agar medium culture showed red pale tan colonies with a concentration >103 CFU. Identification and antibiotic susceptibility were obtained by the Phoenix system (Becton-Dickinson, USA) as Shewanella putrefaciens. This was confirmed by standards and semi-automated microbiological techniques. Gram stain showed Gram-negative bacilli with positive oxidase and catalase reactions. Production of hydrogen sulfide was confirmed by the semi-automated API 20NE method (biomerieux, France). The isolate was resistant to gentamicin, amikacin, ceftazidime, aztreonam, amoxicillin- clavulanic acid, cefepime, trimethoprim/sulfamethoxazole, and nitrofurantoin. In our case, S. putrefaciens was found in a mixed culture with Klebsiella pneumoniae. No earlier exposure of the patient to marine water had been noticed. Blood culture indicated colonies growth of Acinetobacter baumannii. No further isolation of this bacteria was noticed after treatment. The patient was given imipenem, vancomycin and colistin. Despite our best efforts, the patient could not be saved because of sepsis and renal function failure.
Shewanella putrefaciens est une bactérie opportuniste, rarement responsable d’infections humaines. Elle a toutefois été rapportée comme cause d’infections de la peau et des tissus mous (cellulites, abcès, surinfections de plaies) et de bactériémies chez des patients immunodéprimés. C’est un bacille à Gram négatif non fermentant, oxydase et catalase +, producteur de sulfure d’hydrogène. Nous présentons le cas d’une patiente diabétique de 90 ans ayant subi une bactériémie issue d’une surinfection de brûlure à Shewanella putrefaciens. Elle était hospitalisée dans l’hôpital militaire MS. Nekkache d’Alger à la suite d’une brûlure touchant 40% SCT. Une fièvre élevée a été constatée à J7. La culture de l’extrémité distale du cathéter montrait, sur gélose de McConkey, des colonies pâles non fermentantes. Sur milieu enrichi, on observait >103 CFU rouge pâle, identifiées à Shewanella putrefaciens par le système Phoenix (Beckton-Dickinson), identification confirmée par les techniques microbiologiques standard et semi- automatiques. La coloration de Gram était négative, les réactions catalasique et oxydasique étaient positives. La production de sulfure d’hydrogène était par API 20NE semi- automatique (BioMérieux). La bactérie résistait à gentamicine, amikacine, ceftazidime, aztréonam, amoxicilline- acide clavulanique, céfépime, triméthoprime- sulfaméthoxazole et nitrofurantoïne. Shewanella putrefaciens était associée à Klebsiella pneumoniæ et les hémocultures poussaient à Acinetobacter baumannii. Il n’y avait pas de notion d’exposition antérieure à l’eau de mer. La bactérie n’a pas été retrouvée après traitement par imipénème, vancomycine et colimycine. La patiente est toutefois décédée de sepsis et insuffisance rénale aiguë.
