Perioperative research into memory (PRiMe), part 2: Adult burns intensive care patients show altered structure and function of the default mode network. Burns 2024; 50:1908-1915. [PMID: 38890052 DOI: 10.1016/j.burns.2024.05.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 03/24/2024] [Accepted: 05/02/2024] [Indexed: 06/20/2024]
Abstract
BACKGROUND Long-term cognitive impairment (LTCI) is experienced by up to two thirds of patients discharged from burns intensive care units (BICUs), however little is known about its neurobiological basis. This study investigated if patients previously admitted to BICU showed structural and functional MRI changes of the Default Mode Network (DMN). METHODS Fifteen patients previously admitted to BICU with a significant burns injury, and 15 matched volunteers, underwent structural and functional MRI scans. Functional connectivity, fractional anisotropy and cortical thickness of the main DMN subdivisions (anterior DMN (aDMN), posterior DMN (pDMN) and right (rTPJ) and left (lTPJ) temporo-parietal junctions) were compared between patients and volunteers, with differences correlated against cognitive performance. RESULTS Functional connectivity between rTPJ and pDMN (t = 2.91, p = 0.011) and between rTPJ and lTPJ (t = 3.18, p = 0.008) was lower in patients compared to volunteers. Functional connectivity between rTPJ and pDMN correlated with cognitive performance (r2 =0.33, p < 0.001). Mean fractional anisotropy of rTPJ (t = 2.70, p = 0.008) and lTPJ (T = 2.39, p = 0.015) was lower in patients but there was no difference in cortical thickness. CONCLUSIONS Patients previously admitted to BICU show structural and functional disruption of the DMN. Since functional changes correlate with cognitive performance, this should direct further research into intensive-care-related cognitive impairment.

Evaluating the association between time to skin grafting for truncal burn patients and complications: a comparative cohort study using the National Trauma Data Bank. Int J Surg 2024; 110:4581-4587. [PMID: 39143705 PMCID: PMC11325990 DOI: 10.1097/js9.0000000000001461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 03/31/2024] [Indexed: 08/16/2024]
Abstract
BACKGROUND The split-thickness skin graft (STSG) procedure is frequently used in the reconstruction of burn-injured patients. This study assessed the impact of graft timing on associated skin complications in patients with torso burns using a comprehensive national database. METHODS Truncal burn (2nd-degree and 3rd-degree burns covering 20-89% TBSA) patients who underwent STSG in the National Trauma Data Bank from 2011 to 2015 were studied. The outcomes examined were graft-related complications (superficial surgical site infections, deep surgical site infections, and graft failure), overall mortality and hospital length of stay (LOS). Patients were compared based on the presence or absence of grafting complications. A linear regression model was used to assess the relationship between hospital LOS and graft timing, considering other variables. RESULTS Among the 853 studied patients, the cohort with graft complications exhibited a significantly prolonged time to STSG (413.0 h compared to 264.6 h, P<0.001) and a higher percentage of patients with pre-existing diabetes (18.5 vs. 8.0%, P=0.008). The multiple logistic regression analysis revealed that both the extended time to STSG (odds=1.001, P=0.003) and pre-existing diabetes (odds=2.790, P=0.010) significantly elevated the likelihood of complications associated with STSG. Notably, this delay did not elevate mortality risks. A positive relationship was found between grafting delay and LOS. CONCLUSION The findings underscore that a prolonged duration to skin grafting contributes to extended hospital stays and increased graft-related complications. However, the role of grafting delay in influencing the mortality of truncal burn patients appeared inconsequential, indicating that mortality may be influenced by various factors.

[PMID: 38307765 DOI: 10.1016/j.burns.2024.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 11/29/2023] [Accepted: 01/10/2024] [Indexed: 02/04/2024]
Abstract
BACKGROUND The disruption to the immune system and profound metabolic response to burn injury gives rise to a unique susceptibility to infection. Indeed, infection is one of the most frequently encountered post-burns complications placing significant burden on patients and healthcare system. Advancements in burn care have led to marked improvements in burn-related mortality and morbidity; however, scarce hospital resources hamper adequate burn-related care, and patient length of stay (LOS) in hospital is an important drain on such resources. The aim of this review was to assess and evaluate the existing literature relating to the impact of infections on LOS in hospitalised, adult burn patients. METHODS Electronic searches were performed in Medline and Embase. Eligible studies were those reporting on LOS and infection in adult burn populations. Articles published before 2000 were excluded to ensure that the analysis was focused on contemporary literature that reflects current, clinical management of burn patients. RESULTS Nineteen studies (54,397 burn patients) were included in the review. All studies were retrospective, with the majority undertaken in North America (14 studies). The mean age range was 38-67 years and the majority of patients were male. Inhalation injury was recorded in eleven studies. The most common types of infection included pneumonia, blood stream infections (BSI) and burn wound infections. Overall, there was a trend towards a positive association between infection and LOS. CONCLUSION The results of this scoping review provide an overview of the existing literature on the relationship between infection and LOS in adult burn populations. However, significant gaps remain in knowledge which call for further high-quality research. Standardised definitions for the collection of infection data and the use of burns specific infection control guidelines are also critical to understanding and improving patient outcomes.

Abstract
Burns in the elderly are a significant cause of morbidity and mortality. Frailty is an important indicator of patient health and physiologic reserve. Comorbidities and typical age-related changes significantly impact the outcomes of elderly burn patients and decisions made during their burn care. It is essential to have early and thorough discussions about the goals of care and rehabilitation plans. Physiologic changes that occur from aging cause slower wound healing and may make operative treatment more challenging, although techniques such as autographing, skin substitutes, and flaps may all play a role in treating this patient population.

Abstract
Burn injury is associated with a high risk of acute kidney injury (AKI) with a prevalence of AKI among patients with burns of 9-50%. Despite an improvement in burn injury survival in the past decade, AKI in patients with burns is associated with an extremely poor short-term and long-term prognosis, with a mortality of >80% among those with severe AKI. Factors that contribute to the development of AKI in patients with burns include haemodynamic alterations, burn-induced systemic inflammation and apoptosis, haemolysis, rhabdomyolysis, smoke inhalation injury, drug nephrotoxicity and sepsis. Early and late AKI after burn injury differ in their aetiologies and outcomes. Sepsis is the main driver of late AKI in patients with burns and late AKI has been associated with higher mortality than early AKI. Prevention of early AKI involves correction of hypovolaemia and avoidance of nephrotoxic drugs (for example, hydroxocobalamin), whereas prevention of late AKI involves prevention and early recognition of sepsis as well as avoidance of nephrotoxins. Treatment of AKI in patients with burns remains supportive, including prevention of fluid overload, treatment of electrolyte disturbance and use of kidney replacement therapy when indicated.

Abstract
BACKGROUND An increasing aging population alongside a potentially increasing injury risk emphasizes a critical need for evidence-based burn care regarding preventive and therapeutic strategies tailored to the unique needs of older adults. However, we note a critical gap in understanding geriatric burn trends on a global scale and the care capacity across settings. Thus, this study sought to ascertain the global trend of geriatric burns with a focus on patient demographics, injury characteristics, capacities of care, and injury outcomes. METHODS A retrospective design focusing on older adults aged ≥ 60 years with burns recorded in the World Health Organization Global Burn Registry as of 31st May 2023 was employed. Descriptive statistics were employed to analyze the data. RESULTS Of the 9277 records obtained from the Global Burn Registry, 849 participants (9.2%) were aged ≥ 60 years with the majority of these reported from the Eastern Mediterranean (EMRO) and Southeast Asia (SEARO) regions. More females than males were involved in burn injuries with the most common aetiological factor being flame. Most burns occurred in the home/ domestic setting with a seasonal variation (more injuries occurred in December and January). In terms of burn care capacity, the data suggest the availability of specialized services in most settings albeit the AFRO and SEARO regions still lacked the resources to offer specialized burn care. While most injured older adults were discharged home with no physical impairment (395, 46.5%), a substantial number died (250, 29.4%) during hospitalization, particularly in the African (AFRO) region and 111 (11.1%) left the facility against medical advice with the majority from the SEARO region (88). CONCLUSION Burn injuries in older adults remain a public health issue. On the preventive aspect, the results demonstrate a need to intensify safety in the home or domestic setting, and during festive seasons. Therapeutically, the findings underscore a need to consider the inclusion of more specialist geriatric and palliative care services in the burn management process. Additionally, we identified a need to strengthen burn care capacity in the AFRO and SEARO regions.

Cohort analysis of 50% lethal area (LA50) and associating factors in burn patients based on quality improvements and health policies. Sci Rep 2023; 13:19034. [PMID: 37923785 PMCID: PMC10624683 DOI: 10.1038/s41598-023-45884-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2023] [Accepted: 10/25/2023] [Indexed: 11/06/2023] Open
Abstract
Burn injuries are among the common traumatic injuries, which can be accompanied with lifelong morbidity and mortality. The Lethal Area Fifty Percent (LA50) index is another reliable outcome measurement tool that assesses the standard of medical care at burn centers. It is widely used as a benchmark for assessing the quality of burn care and is considered the percentage at which 50% of burn patients are expected to die because of burn-related injuries. We aimed to determine and compare the LA50 in burn patients admitted to Shiraz Burn Referral Centers in 2018-2021 and 2011-2018 with regard to improving the quality of special care and infection control in the new hospital. We conducted a retrospective cohort analysis on patients admitted to Amir al-Momenin Burn Injury Hospital in Shiraz, Fars, Southern Iran. Data were retrospectively gathered from March 2011 to January 2022, and subsequently analyzed with standard statistical analysis, and also multivariate and probability analysis. A total of 7382 patients with acute burns injuries were identified. Among them, 4852 (65.7%) patients were men, and the median age was 27 years [Q1-Q3 7-40; range 1-98]. Most of the patients were in the pediatric and early adulthood age range, with 76.2% being younger than 40 years old. The median TBSA was 24% [IQR 14, 43], and the median duration of hospitalization was 11 [IQR 11] days. Most injuries were secondary to flame and fire (33.5%; n = 2472). The mortality rate in our study was 19.0% (n = 1403). We evaluated our patients based on two main time intervals: March 2011 till February 2018 (n = 3409; 46.2%), and March 2018 to January 2022 (n = 3973; 53.8%). Based on multivariate analysis, the second interval of our study was significantly correlated with a more female patients, higher age, lower TBSA, less burn injuries due to scald, contact, but more frequent fire and flame injuries, and also lower mortality rate. Factors correlated with higher mortality included male gender, older age, shorter hospitalization duration, higher TBSA, etiology of fire and flame, and accidental burn injuries. A Baux score of 76.5 had a sensitivity of 81.1%, specificity of 87.3%, accuracy of 86.1% in predicting mortality among our patients. The mortality probability for the study intervals were 20.67% (SD 33.0%) for 2011-2018, and 17.02% (SD 29.9%) for 2018-2022 (P < 0.001). The LA50 was 52.15 ± 2 for all patients. This ammount was 50 ± 2% in 2011-2018, and 54 ± 2 in 2018-2022 (P < 0.001). The mean LA50 values showed significant improvements following significant modifications in our critical care for burn victims, including augmented intensive care unit capacity, prompt relocation of inhalation burn cases to the intensive care unit, establishing a well-trained multidisciplinary team, and improved infection control. To improve outcomes for burn patients in developing countries, major changes should be made in the management of burn patients and LA50 is a reliable assessment tool for evaluating the how these changes affect patient's outcomes.

Abstract
The number of older people is increasing and as a result so will the number of older adult patients who present with a burn injury. There are distinct differences between older and younger burn patients, particularly with respect to skin anatomy and physiology and frailty. These are 2 important factors that influence the rehabilitation efforts with respect to older adult burn patients. There has been minimal work done studying the specific rehabilitation of older adult burn patients. More work is needed to fully understand the rehabilitation needs of older adult burn patients.

Abstract
The treatment of geriatric burn patients represents a major challenge in burn care. The objective of this study was to evaluate the efficacy of enzymatic debridement (ED) in geriatric burn patients. Adult patients who received ED for treatment of mixed pattern and full thickness burns (August 2017–October 2022) were included in this study and grouped in the younger (18–65 years) and geriatric (≥65 years) groups. Primary outcome was a necessity of surgery subsequent to ED. Both groups (patient characteristics, surgical and non-surgical treatment) were compared. Multiple logistic and linear regression models were used to identify the effect of age on the outcomes. A total of 169 patients were included (younger group: 135 patients, geriatric group: 34 patients). The burn size as indicated by %TBSA (24.2 ± 20.4% vs. 26.8 ± 17.1%, p = 0.499) was similar in both groups. The ASA (2.5 ± 1.1 vs. 3.4 ± 1.1, p < 0.001) and ABSI scores (6.1 ± 2.8 vs. 8.6 ± 2.3, p < 0.001) were significantly higher in the geriatric group. The %TBSA treated with ED (5.4 ± 5.0% vs. 4.4 ± 4.3%, p = 0.245) were similar in both groups. The necessity of additional surgical interventions (63.0 % vs. 58.8 %, p = 0.763) and the wound size debrided and grafted (2.9 ± 3.5% vs. 2.2 ± 2.1%; p = 0.301) were similar in both groups. Regression models yielded that age did not have an effect on efficacy of ED. We showed that ED is reliable and safe to use in geriatric patients. Age did not have a significant influence on the surgical outcomes of ED. In both groups, the size of the grafted area was reduced and, in many patients, surgery was avoided completely.

Abstract
The predictive capability of various risk assessment models (RAMs) in evaluating the risk of mortality in burn patients is not well established. It is also unclear which RAM provides the highest discriminative ability and presents the highest clinical utility. We pooled all available studies to establish this validity and compare the predictive capability of the various RAMs. Methods We reviewed PubMed, MEDLINE, and Embase from their inception up until December 2021 for studies evaluating risk of mortality in burn patients as stratified by RAMs. Data were pooled using random-effect models and presented as area under the receiver operating characteristic (AUROC) curve. Results Thirty-four studies, comprising of a total of 98,610 patients, were included in our analysis. Most studies were found to have a low risk of bias and a good measure of applicability. Nine RAMs were evaluated. We discovered that the classic Baux; the revised Baux; and the Fatality by Longevity, APACHE II score, Measured Extent of burn, and Sex (FLAMES) scores presented with the highest discriminative power with there being no significant difference between the results presented by them [AUROCs (95% CI), 0.92 (0.90-0.95), 0.92 (0.90-0.93), 0.94 (0.91-0.97), respectively, with P < 0.00001 for all]. Conclusions Many RAMs exist with no consensus on the optimal model to utilize and assess risk of mortality for burn patients. This study is the first systematic review and meta-analysis to compare the current RAMs' discriminative ability to predict mortality in patients with burn injuries. This meta-analysis demonstrated that RAMs designed for assessing mortality in individuals with burns have acceptable to great discriminative capacity, with the classic Baux, revised Baux, and FLAMES demonstrating superior discriminative performance in predicting death. FLAMES exhibited the highest discriminative ability among the RAMs studied.

Machine learning links different gene patterns of viral infection to immunosuppression and immune-related biomarkers in severe burns. Front Immunol 2022; 13:1054407. [PMID: 36518755 PMCID: PMC9742460 DOI: 10.3389/fimmu.2022.1054407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Accepted: 11/08/2022] [Indexed: 11/29/2022] Open
Abstract
Introduction Viral infection, typically disregarded, has a significant role in burns. However, there is still a lack of biomarkers and immunotherapy targets related to viral infections in burns. Methods Virus-related genes (VRGs) that were extracted from Gene Oncology (GO) database were included as hallmarks. Through unsupervised consensus clustering, we divided patients into two VRGs molecular patterns (VRGMPs). Weighted gene co-expression network analysis (WGCNA) was performed to study the relationship between burns and VRGs. Random forest (RF), least absolute shrinkage and selection operator (LASSO) regression, and logistic regression were used to select key genes, which were utilized to construct prognostic signatures by multivariate logistic regression. The risk score of the nomogram defined high- and low-risk groups. We compared immune cells, immune checkpoint-related genes, and prognosis between the two groups. Finally, we used network analysis and molecular docking to predict drugs targeting CD69 and SATB1. Expression of CD69 and SATB1 was validated by qPCR and microarray with the blood sample from the burn patient. Results We established two VRGMPs, which differed in monocytes, neutrophils, dendritic cells, and T cells. In WGCNA, genes were divided into 14 modules, and the black module was correlated with VRGMPs. A total of 65 genes were selected by WGCNA, STRING, and differential expression analysis. The results of GO enrichment analysis were enriched in Th1 and Th2 cell differentiation, B cell receptor signaling pathway, alpha-beta T cell activation, and alpha-beta T cell differentiation. Then the 2-gene signature was constructed by RF, LASSO, and LOGISTIC regression. The signature was an independent prognostic factor and performed well in ROC, calibration, and decision curves. Further, the expression of immune cells and checkpoint genes differed between high- and low-risk groups. CD69 and SATB1 were differentially expressed in burns. Discussion This is the first VRG-based signature (including 2 key genes validated by qPCR) for predicting survival, and it could provide vital guidance to achieve optimized immunotherapy for immunosuppression in burns.

Abstract
Abstract
Whereas older age predicts higher burn mortality, the impact of age on discharge disposition is less well defined in older adults with burns. This investigation assesses the relationship between older age and discharge disposition after burns in a nationally representative sample. We queried the 2007-2015 National Trauma Data Bank for non-fatal burn hospitalizations in older adults. Pre-defined age categories were 55-64 years (working-age comparison group), 65-74 years (young-old), 75-84 years (middle-old), and 85+ years (old-old). Covariables included inhalation injury, comorbidities, burn total body surface area, injury mechanism, and race/ethnicity. Discharge to non-independent living (nursing home, rehabilitation, and other facilities) was the primary outcome. Logistic regression assessed the association between older age and discharge to non-independent living. There were 25,840 non-fatal burn hospitalizations in older adults during the study period. Working-age encounters comprised 53% of admissions, young-old accounted for 28%, middle-old comprised 15% and old-old comprised 4%. Discharge to non-independent living increased with burn TBSA and older age in survivors. Starting in young-old, the majority (65 %) of patients with burns ≥20% TBSA were discharged to non-independent living. Adjusted odd ratios for discharge to non-independent living were 2.0 for young-old, 3.3 for middle-old and 5.6 for old-old patients, when compared to working-age patients (all p<0.001). Older age strongly predicts non-independent discharge after acute burn hospitalization. Matrix analysis of discharge disposition indicates a stepwise rise in discharge to non-independent living with higher age and TBSA, providing a realistic discharge framework for treatment decisions and expectations about achieving independent living after burn hospitalization.

Abstract
Severe burns may lead to a series of pathophysiological processes that result in death. Machine learning models that demonstrate prognostic performance can be used to build analytical models to predict postoperative mortality. This study aimed to identify machine learning models with the best diagnostic performance for predicting mortality in critically ill burn patients after burn surgery, and then compare them. Clinically important features for predicting mortality in patients after burn surgery were selected using a random forest (RF) regressor. The area under the receiver operating characteristic curve (AUC) and classifier accuracy were evaluated to compare the predictive accuracy of different machine learning algorithms, including RF, adaptive boosting, decision tree, linear support vector machine, and logistic regression. A total of 731 patients met the inclusion and exclusion criteria. The 90-day mortality of the critically ill burn patients after burn surgery was 27.1% (198/731). RF showed the highest AUC (0.922, 95% confidence interval = 0.902–0.942) among the models, with sensitivity and specificity of 66.2% and 93.8%, respectively. The most significant predictors for mortality after burn surgery as per machine learning models were total body surface area burned, red cell distribution width, and age. The RF algorithm showed the best performance for predicting mortality.

Abstract
BACKGROUND Burn injuries in geriatric patients are common and may have significant associated morbidity and mortality. Most research has focused on the care of hospitalized patients after admission to burn units. Little is known about the clinical characteristics of geriatric burn victims who present to the emergency department (ED) and their ED assessment and management. OBJECTIVE Our aim was to describe the clinical characteristics and outcomes of geriatric patients presenting to the ED with burn injuries. METHODS We performed a comprehensive retrospective chart review on all patients 60 years and older with a burn injury presenting from January 2011 through September 2015 to a large, urban, academic ED in a hospital with a 20-bed burn center. RESULTS A total of 459 patients 60 years and older were treated for burn injuries during the study period. Median age of burn patients was 71 years, 23.7% were 80 years and older, and 56.6% were female. The most common burn types were hot water scalds (43.6%) and flame burns (23.1%). Median burn size was 3% total body surface area (TBSA), 17.1% had burns > 10% TBSA, and 7.8% of patients had inhalation injuries. After initial evaluation, 46.4% of patients were discharged from the ED. Among patients discharged from the ED, only 1.9% were re-admitted for any reason within 30 days. Of the patients intubated in the ED, 7.1% were extubated during the first 2 days of admission, and 64.3% contracted ventilator-associated pneumonia. CONCLUSIONS Better understanding of ED care for geriatric burn injuries may identify areas in which to improve emergency care for these vulnerable patients.

Burn injuries in the older population and understanding the common causes to influence accident prevention. Burns 2022; 49:848-853. [PMID: 36813606 DOI: 10.1016/j.burns.2022.06.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 05/18/2022] [Accepted: 06/27/2022] [Indexed: 11/20/2022]
Abstract
INTRODUCTION The over 65 years old are a fast growing population leading to a future increase in patients. Burn injuries can have a serious effect on a patient's health, requiring longer hospital stays and affecting their mortality. The regional burns unit at Pinderfields General Hospital cares for all patients with burn injuries in the Yorkshire and Humber region in the United Kingdom. The aim of this study was to understand the common causes of burn injury in the elderly population and to provide scope on what actions need to be carried out to influence accident prevention in the future. METHODS In this study, patients were aged 65 years or older and had to have been admitted for a minimum of one night to the regional burns unit at Yorkshire, England from January 2012. The data was collected from the International Burn Injury Database (iBID), which included a total number of 5091 patients. After the inclusion and exclusion criteria were applied there were a total number of 442 patients over 65 years old. The data was analysed using descriptive analysis. RESULTS 13.0% of all patients admitted with a burn injury were over 65 years old. In the over 65 years old, 31.2% of burn injuries were most common during the activity of food preparation. Out of all the burn injuries within food preparation 75.4% were due to a scald injury. Additionally, 42.3% of scald burns from food preparation were due to hot fluid spills from a kettle or saucepan, rising to 73.1% after including burns from cups of tea and coffee. 21.2% of scalds from food preparation were caused by cooking with hot oil. CONCLUSIONS The main cause of burn injuries in the elderly of Yorkshire and Humber was food preparation. The majority of the food preparation burn injuries were a scald burn due to the handling of hot fluids, either from a saucepan or a kettle. A prevention strategy aiming to make people aware of this finding can help reduce burn injuries in the over 65 years old age group.

Abstract
BACKGROUND Infections are a major cause of morbidity in burn patients. We aimed to investigate the epidemiology and antibiotic susceptibility of blood stream infections in order to gain a better understanding of their role and burden in our Burn Wound Center. METHODS This retrospective epidemiological investigation analyzed data derived from medical files of patients admitted to our Burn Wound Center having had at least one positive blood culture between 1 January and 31 December 2018. We focused on the prevalence of causative agents in blood stream infections in function of the time after injury and on their drug sensitivity. RESULTS Among the 363 patients admitted to our Burn Wound Center during the study period, 29 had at least one episode of blood stream infection. Gram-negative organisms accounted for 56,36% of the pathogens in blood stream infections, Gram-positives for 38,17%, and yeasts for 5,45%. Pseudomonas aeruginosa was the most common bacterium (20%), followed by Staphylococcus epidermidis (16.36%), Escherichia coli and Klebsiella pneumoniae (9,09% each). A third of the Gram-negative isolates were multidrug resistant. Gram-positive cocci were isolated from blood cultures at a median of 9 days after the injury, earlier than Gram-negative rods (median 15 days). The main sources of blood stream infections were the burn wounds, followed by infected catheters. CONCLUSIONS Multidrug resistant bacteria must be considered when selecting empirical antibiotic therapy in septic burn patients. In our center, we need to update our antibiotic guidelines, to review the hospital infection control measures and to introduce routine typing technology.

Abstract
Background: The older adult population continues to rapidly expand in number, with a projection by the United States (US) Census Bureau that there will be more individuals older than > 65 years (77.0 million) than those younger than < 18 years (76.5 million) by 2034. This review provides an overview of aging as it relates to wound healing and burn injuries in older adult patients, summarizes current treatment practices, and addresses the key challenges and considerations for treating severe burn injuries in this specific patient population. Materials and methods: A narrative literature search was conducted, focusing on recent primary literature on burns and wound healing in elderly patients. Results: Studies showed that the aging process results in both physiologic (eg, nutritional and metabolic status) and anatomic changes (eg, thinning dermis) that contribute to a reduced capacity to recover from burn-injury trauma compared with younger patients. Owing to impaired vision, decreased coordination, comorbidities, and medication-induced side effects, older adults (ie, > 65 years) are susceptible to severe burn injury (deep-partial thickness and full-thickness), which is associated with significant morbidity and mortality. Conclusion: A better understanding of the effects of age-related changes regarding wound healing in older adult patients who incur severe burn injuries may provide insight into clinical strategies to improve outcomes among this population.

Abstract
Burns cause greater morbidity and mortality in older patients owing to the physiological changes and functional status declines with age. We sought to characterize the epidemiology of burn injuries in the patient population aged over eighty years. A retrospective analysis of all patients aged >80 years admitted to a tertiary burn center in Brazil over a 10-year period was conducted. Multiple parameters including comorbidities, body surface area(BSA) burned, intensive care unit(ICU) admissions, inhalation injury and revised Baux score were analyzed to assess association with mortality. 26 patients were identified. The overall mortality rate was 42.3%. The mortality rate increased with the TBSA, with 100% mortality at >20% total BSA involvement(p<0.001). Inhalation injury occurred in 3(11.5%) patients, all of whom suffered mortality(p<0.001). ICU admission was necessary for 14(53.8%) patients, out of which 11(78.6%) did not survive(p<0.001). The revised Baux score had a significant impact on the mortality, with higher values among patients who did not survive(89.2 ± 6.2 versus 110.7 ± 17.9,p < 0.001). Burns cause high mortality in the octogenarian and nonagenarian populations. It is important to stratify patients at high risk, institute prompt treatment and discuss goals of care early on for optimal patient outcomes.

Abstract
OBJECTIVE The burden of the management of problematic skin wounds characterised by a compromised skin barrier is growing rapidly. Almost six million patients are affected in the US alone, with an estimated market of $25 billion annually. There is an urgent requirement for efficient mechanism-based treatments and more efficacious drug delivery systems. Novel strategies are needed for faster healing by reducing infection, moisturising the wound, stimulating the healing mechanisms, speeding up wound closure and reducing scar formation. METHODS A systematic review of qualitative studies was conducted on the recent perspectives of nanotechnology in burn wounds management. Pubmed, Scopus, EMBASE, CINAHL and PsychINFO databases were all systematically searched. Authors independently rated the reporting of the qualitative studies included. A comprehensive literature search was conducted covering various resources up to 2018-2019. Traditional techniques aim to simply cover the wound without playing any active role in wound healing. However, nanotechnology-based solutions are being used to create multipurpose biomaterials, not only for regeneration and repair, but also for on-demand delivery of specific molecules. The chronic nature and associated complications of nonhealing wounds have led to the emergence of nanotechnology-based therapies that aim at facilitating the healing process and ultimately repairing the injured tissue. CONCLUSION Nanotechnology-based therapy is in the forefront of next-generation therapy that is able to advance wound healing of hard-to-heal wounds. In this review, we will highlight the developed nanotechnology-based therapeutic agents and assess the viability and efficacy of each treatment. Herein we will explore the unmet needs and future directions of current technologies, while discussing promising strategies that can advance the wound-healing field.

Abstract
BACKGROUND The treatment and management of massive burns, defined as burns affecting≥ 50% of total body surface area (TBSA) has considerably changed since the 90s. This study aimed at analyzing if the length of intensive care unit (ICU) stay, the success of skin grafting operations and the mortality changed in the last 18 years. METHODS Between 2000 and 2018, 77 patients were admitted for massive burns to the ICU of a university hospital. Transfers and early care withdrawal precluded inclusion for 38 patients, leaving 39 for analysis. Study variables were year of admission, demographics, burn characteristics, critical care treatment (fluid resuscitation, ventilation and nutrition) and surgical therapy. Association between outcomes and year of admission were assessed through correlation and logistic regression analysis. Potential confounders were assessed through stepwise linear regression. RESULTS Patients' characteristics were stable over time with a median age of 36[25.0, 48.0] years, burns 65% [55.0, 83.0] TBSA and deep burns 55% [50.0, 68.0] TBSA . Length of ICU stay remained stable at 0.97 [0.6, 1.5] days/%TBSA. Mortality was stable as well. Energy and carbohydrate delivery decreased in parallel with the number of infectious episodes per patient. Number of operations was stable but the take rate of skin grafts increased significantly. The multivariate analysis retained year of admission, weight, total number of infections, daily lipid intakes and fluid resuscitation as independent predicting variables. CONCLUSION Length of ICU stay and mortality did not change over time but skin grafts take rates improved significantly.

Abstract
BACKGROUND Elderly burn patients exhibit a lower survival rate compared with younger counterparts. The liver is susceptible to damage after burn injury, which predisposes to poor outcomes. Lipid homeostasis and the antioxidant glutathione system play fundamental roles in preserving liver integrity. Herein, we explored changes in these major pathways associated with liver damage in the aging animals after burn injury. METHODS We compared liver enzymes, histology, lipid-peroxidation, and glutathione-metabolism profiles from young and aged female mice after a 15% total body surface area burn. Mice were euthanized at 24 hours after injury, and livers and serum were collected. RESULTS Aged burn animals exhibited elevated (p < 0.05) aspartate aminotransferase and alanine aminotransferase levels and increased inflammatory cell infiltration, edema, and necrosis compared with their younger counterparts. The percentage of adipophilin-stained area in livers from young sham, young burn, aged sham, and aged burn groups was 10%, 44%, 16%, and 78% (p < 0.05), respectively. Liver malondialdehyde levels were 1.4 ± 0.5 nmol/mg, 2.06 ± 0.2 nmol/mg, 1.81 ± 0.12 nmol/mg, and 3.45 ± 0.2 nmol/mg (p < 0.05) in young sham, young burn, aged sham, and aged burn mice, respectively. Oxidized glutathione (GSSG) content increased 50% in the young burn, and 88% in aged burn animals compared with the young sham group (p < 0.05). The reduced glutathione GSH/GSSG ratio was significantly reduced by 54% in aged burn mice compared with young sham animals (p < 0.05). Furthermore, glutathione peroxidase gene expression showed a 96% decrease in the aged burn group compared with young sham mice (p < 0.05). CONCLUSION Aged burn animals exhibit severe liver damage from heightened lipid peroxidation and inadequate antioxidative response. The increased peroxidation is associated with abundant lipid deposits in hepatic tissue postburn and a weak antioxidative response due to hepatic glutathione peroxidase downregulation. Further studies will focus on the functional significance of these findings concerning hepatic homeostasis.

Abstract
Burn is an under-appreciated trauma that is associated with unacceptably high morbidity and mortality. Although the survival rate after devastating burn injuries has continued to increase in previous decades due to medical advances in burn wound care, nutritional and fluid resuscitation and improved infection control practices, there are still large numbers of patients at a high risk of death. One of the most common complications of burn is sepsis, which is defined as “severe organ dysfunction attributed to host's disordered response to infection” and is the primary cause of death in burn patients. Indeed, burn injuries are accompanied by a series of events that lead to sepsis and multiple organ dysfunction syndrome, such as a hypovolaemic state, immune and inflammatory responses and metabolic changes. Therefore, clear diagnostic criteria and predictive biomarkers are especially important in the prevention and treatment of sepsis and septic shock. In this review, we focus on the pathogenesis of burn wound infection and the post-burn events leading to sepsis. Moreover, the clinical and promising biomarkers of burn sepsis will also be summarized.

Abstract
Elderly suffer worse outcomes from burns; thus, it is important to identify the causes of burns in the elderly to develop burn prevention campaigns. We performed a 10-year review of burns that were registered in the NEISS database. We included patients at least 65 years old and analyzed the top five products that caused burn injury. In adults 65 to 74 years old, hot water was the most common cause of burns. Women suffered more burns by candles and cookware. Heaters/heating systems and gasoline were among the top five causes of burns in only men. For the age group 75 to 84 years old, the most common burn was from hot water in women and gasoline in men. For women, the top five included candles, nightwear, and cookware. Only men suffered gasoline burns. The majority of daywear, home/room fire, and ranges/ovens caused burns occurred in men. The majority of burns from hot water, ranges/ovens, electric heating pads, and bathtubs/showers occurred in women. For men, burns from gasoline, structural fires, and heaters are more prevalent. This data can be used to develop age- and gender-specific prevention campaigns to reduce the risk of burn injury.

Abstract
Efforts have been made to determine new predictors of morbidity and mortality in patients with severe burn injuries. This prospective cohort study aimed to determine the association of serum albumin concentration on admission and renal failure, pulmonary infection, sepsis, and death in patients with burn injuries. We included 141 patients, aged >18 years, who were admitted to our institution between April and August 2018. Among them, 59.1% were male and 83.8% had burns covering <20% of the body surface area. Scalds were the most common cause of burns (34.8%). Twelve patients died, of whom eight (66.6%) had an Abbreviated Burn Severity Index (ABSI) ≥8. Patients with serum albumin ≤2.2 g/dL had a higher mortality rate than those with >2.2 g/dL (odds ratios [OR]: 18.7; 95% confidence interval [CI]: 4.9-70.8). Serum albumin ≤2.2 g/dL was also significantly associated with pulmonary infection (OR: 13.1, 95%CI: 3.8-45.7), renal failure (OR: 30.2, 95% CI: 7.4-122.3), and sepsis (OR: 16.9, 95% CI: 4.9-58.3). Serum albumin concentration cut-points and ABSIs were determined to be death predictors using areas under the receiver operating characteristic curves (AUCs). The AUCs with albumin or ABSI alone were 0.89 (95% CI: 0.79-0.98) and 0.92 (95% CI: 0.87-0.96), respectively. The AUC including both albumin and ABSI was 0.96 (95% CI: 0.90-0.98), indicating that the combination is a better death predictor than either measure alone. We confirmed that burn patients with a serum albumin concentration ≤2.2 g/dL on admission have substantially increased morbidity and mortality.

Abstract
PURPOSE To examine the associations between premorbid nutritional status and in-hospital mortality in severe burn patients according to age in Japan. METHODS We retrospectively extracted the data of 14,345 patients aged 18-84 years admitted for burns from April 1, 2014, to March 31, 2018, using the Japanese Diagnosis Procedure Combination database. The exclusion criteria were out-of-hospital cardiac arrest, death in the emergency room, readmission, and planned admission. We collected data on age, sex, height, weight, comorbidities, burn index, and mechanical ventilation use and performed age-stratified multilevel logistic regression analyses to estimate associations between premorbid body mass index (BMI) and in-hospital mortality. RESULTS We analyzed 2968 patients with a burn index ≥10, including 831 elderly aged 75-84 years. In patients aged 18-74 years, being underweight (BMI < 18.5) significantly decreased mortality (0.34 [0.15-0.77]; P = 0.010). In contrast, in patients aged 75-84 years, being underweight significantly increased mortality (2.11 [1.05-4.25]; P = 0.036). Being overweight (BMI >25) increased mortality in both age groups, but not significantly. CONCLUSIONS The results suggest that pre-morbidly underweight elderly patients aged 75-84 years with severe burns have high mortality risks. Further research is needed to identify optimal care strategies for this population.

BURNS & TRAUMA 2020; 8:tkaa027. [PMID: 33123606 PMCID: PMC7579337 DOI: 10.1093/burnst/tkaa027] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/19/2020] [Revised: 03/16/2020] [Accepted: 05/24/2020] [Indexed: 11/14/2022]
Abstract
Background In modern-day burn care, advanced age remains an important predictor for mortality among burn victims. In this study, we compared the complete treatment trajectory (including pre-hospital and surgical treatment) and the outcomes between an elderly burn population and a younger adult burn population. Methods In this nationwide study, data from the Dutch Burn Repository were used. This is a uniform national registration for Dutch specialized burn care. All adult patients that were admitted to one of the three Dutch burn centres from the period 2009 to 2015 were included in the analysis. Burn patients were considered as elderly when ≥65 years of age, and were then further subdivided into three age categories: 65-74, 75-85 and 85+ years. Younger adults in the age category 18-64 years were used as the reference group.Surgical management was studied comprehensively and included timing of surgery, the number of procedures and details on the surgical technique, especially the technique used for debridement and the grafting technique that was applied.For the comparison of clinical outcome, the following parameters were included: mortality, wound infections, length of stay/TBSA (total body surface area) burned, discharge disposition and secondary reconstructions. Results During the study period, 3155 adult patients were included (elderly, n = 505). Burn severity, reflected by the median TBSA, varied between 3.2-4.0% and was comparable, but aetiology and pre-hospital care were different between elderly and the younger adult reference group.Surgical treatment was initiated significantly faster in elderly burn patients (p < 0.001). Less selective techniques for surgical debridement were used in the elderly burns patients (hydrosurgery, 42.0% vs 23.5-22.6%), and on the other hand more avulsion (5.3% vs 7.3-17.6%) and primary wound closure (6.7% vs 24.5%). The most frequently used grafting technique was meshed skin grafts (79.2-88.6%); this was not related to age.Mortality increased rapidly with a higher age and showed a high peak in the 85+ category (23.8%). Furthermore, considerable differences were found in hospital discharge disposition between the elderly and the reference group. Conclusions In conclusion, elderly burn patients who require specialized burn care are vulnerable and medically challenging. Differences in aetiology, comorbidity, physiology and the management prior to admission possibly affect the initial surgical management and result in significantly worse outcomes in elderly. Elderly patients need optimal, timely and specialized burn care to enhance survival after burn injuries.

Abstract
Background: Infection is the greatest cause of mortality in burn patients. As our population ages, the need to care for elderly burn patients will increase, and with it our understanding of how infection affects older patients with burn injuries. This article presents a review of the available literature on the effect of aging on the physiologic response to burns, of the known effects of infection in the elder population, and of the contribution of underlying medical comorbidities to the outcomes for the elderly burn patient. The potential for more serious outcomes from multi-drug resistance in the elder population is also discussed. Methods: This article is a review of the available literature on infection in elderly burn patients. A literature search was performed for key words: elderly; geriatric; burn; infection; comorbidity; multi-drug resistance; central line; urinary tract infection; and burn sepsis. Relevant findings were included in each section. Results: Pre-existing conditions are common in the elderly and contribute to a higher rate of development of pneumonia, cellulitis, urinary tract infection, central line infections, and burn wound infections. Specific data pertaining to infections in the elderly burn population are scarce or confined to single-center reports. Conclusions: Because of the inherent susceptibility of the elder population to infection because of pre-existing medical conditions, immunosenescence, and potential exposure via frequent interaction with the medical system, vigilance must be maintained for preventing and treating infection in elderly burn patients. More research is needed to define the risks and extent of this increasingly important issue.

Abstract
AIM We aim to investigate the diagnostic value of newly defined criteria for the systemic inflammatory response syndrome (SIRS) for paediatric burn patients by the American Burn Association (ABA) by comparing the non-burn-specific SIRS criteria for children. METHODS A total of 147 paediatric burn patients were included in this study. Patients diagnosed with sepsis were included in the sepsis group. Clinical parameters were obtained from the electronic medical records at the time of preliminary sepsis diagnosis. Both the non-burn-specific SIRS criteria and the burn-specific ABA SIRS criteria were applied to both the sepsis group and the non-sepsis group. RESULTS Of 147 patients, 50 had sepsis according to the non-burn-specific sepsis criteria. When the 50-patient sepsis group was compared to the 97-patient non-sepsis group, the sepsis group had a significantly higher duration of hospitalisation, burn percentage, burn state and abbreviated burn scoring index (ABSI) (P < 0.05). The specificity of the two scales was 29.9% for the non-burn-specific SIRS and 74.2% for the burn-specific ABA SIRS. The sensitivity for the burn-specific ABA SIRS was calculated as 58%, the sensitivity for the non-burn-specific SIRS was 100%. While positive predictive value was calculated as 42.4% for the non-burn-specific SIRS, this value was found as 53.7% for the burn-specific ABA SIRS criteria. The correlation coefficient between the non-burn-specific SIRS and the burn-specific ABA SIRS was 0.378 (P < 0.001). CONCLUSIONS Our study underlines the need for widespread use of more specific and sensitive burn-specific clinical criteria to early diagnosis of infection in burn patients to prevent unnecessary antibiotic usage.

Abstract
Nutrition is a critical component of acute burn care and wound healing. There is no consensus over the appropriate timing of initiating enteral nutrition in geriatric burn patients. This study aimed to assess the impact of early enteral nutrition on outcomes in this patient population. We performed a 1-year (2017) analysis of the American College of Surgeons Trauma Quality Improvement Program and included all older adult (age ≥65 years) isolated thermal burn patients who were admitted for more than 24 hr and received enteral nutrition. Patients were stratified into two groups based on the timing of initiation of feeding: early (≤24 hr) vs late (>24 hr). Multivariate logistic regression was performed to control for potential confounding factors. Outcome measures were hospital and intensive care unit lengths of stay, in-hospital complications, and mortality. A total of 1,004,440 trauma patients were analyzed, of which 324 patients were included (early: 90 vs late: 234). The mean age was 73.9 years and mean TBSA burnt was 31%. Patients in the early enteral nutrition group had significantly lower rates of in-hospital complications and mortality (15.6% vs 26.1%; P = 0.044), and a shorter hospital length of stay (17 [11,23] days vs 20 [14,24] days; P = 0.042) and intensive care unit length of stay (13 [8,15] days vs 17 [9,21] days; P = 0.042). In our regression model of geriatric burn patients, early enteral nutrition was associated with improved outcomes. The cumulative benefits observed may warrant incorporating early enteral nutrition as part of intensive care protocols.

Abstract
Because of the intrinsic complexity, the classification of wounds is important for the diagnosis, management, and choosing the correct treatment based on wound type. Generally, burn injuries are classified as a class of wounds in which injury is caused by heat, cold, electricity, chemicals, friction, or radiation. On the other hand, wound healing is a complex process, and understanding the biological trend of this process and differences in the healing process of different wounds could reduce the possible risk in many cases and greatly reduce the future damage to the injured tissue and other organs. The aim of this review is to provide a general perspective for the burn wound location among the other types of injuries and summarizing as well as highlighting the differences of these types of wounds with emphasizing on factors affecting thereof.

Abstract
INTRODUCTION The ageing global population presents a novel set of challenges for trauma systems. Less research has focused on the older adult population with burns and how they differ compared to younger patients. This study aimed to describe, and compare with younger peers, the number, causes and surgical management of older adults with burn injuries in Australia and New Zealand. METHODS The Burns Registry of Australia and New Zealand was used to identify patients with burn injuries between 1 July 2009 and 31 December 2018. Temporal trends in incidence rates were evaluated and categorised by age at injury. Patient demographics, injury severity and event characteristics, surgical intervention and in-hospital outcomes were investigated. RESULTS There were 2394 burn-injured older adults admitted during the study period, accounting for 13.4% of adult admissions. Scalds were the most common cause of burn injury in older adults. The incidence of older adult burns increased by 2.96% each year (incidence rate ratio = 1.030, 95% confidence interval = 1.013-1.046, P < 0.001). Compared to their younger peers, a smaller proportion of older adult patients were taken to theatre for a surgical procedure, though a larger proportion of older adults received a skin graft. DISCUSSION Differences in patient and injury characteristics, surgical management and in-hospital outcomes were observed for older adults. These findings provide the Australian and New Zealand burn care community with a greater understanding of burn injury and their treatments in a unique group of patients who are at risk of poorer outcomes than younger people. LAY SUMMARY The number and proportion of older persons in every country of the world is growing. This may create challenges for healthcare systems. While burn injuries are a unique subset of trauma that affect individuals of all ages, less is known about burns in older adults and how they differ from younger patients.We wanted to look at the number, type, management, and outcomes of burns in older adults in Australia and New Zealand. To do this, we used data from the Burns Registry of Australia and New Zealand, or BRANZ. The BRANZ is a database that collects information on patients that present to Australian and New Zealand hospitals that have a specialist burns unit.Our research found that one in eight adult burns patients was over the age of 65, and that the rate of burn injuries in older adults has increased over the last decade. Older adult burns patients were most commonly affected by scalds after coming in contact with wet heat such as boiling liquids or steam. Fewer older adults went to theatre for an operation or surgical procedure compared to their younger counterparts. However, a larger proportion of older adults that went to theatre had a skin graft (where skin is removed from an uninjured part of the body and placed over the injured part).This research provides important information about a unique and growing group of patients to the local burn care community. It also highlights potential avenues for injury prevention initiatives.

Lip HTC, Idris MAM, Imran FH, Azmah TN, Huei TJ, Thomas M. Predictors of mortality and validation of burn mortality prognostic scores in a Malaysian burns intensive care unit. BMC Emerg Med 2019; 19:66. [PMID: 31699024 PMCID: PMC6839226 DOI: 10.1186/s12873-019-0284-8] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Accepted: 10/24/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Majority burn mortality prognostic scores were developed and validated in western populations. The primary objective of this study was to evaluate and identify possible risk factors which may be used to predict burns mortality in a local Malaysian burns intensive care unit. The secondary objective was to validate the five well known burn prognostic scores (Baux score, Abbreviated Burn Severity Index (ABSI) score, Ryan score, Belgium Outcome Burn Injury (BOBI) score and revised Baux score) to predict burn mortality prediction. METHODS Patients that were treated at the Hospital Sultan Ismail's Burns Intensive Care (BICU) unit for acute burn injuries between 1 January 2010 to 31 December 2017 were included. Risk factors to predict in-patient burn mortality were gender, age, mechanism of injury, total body surface area burn (TBSA), inhalational injury, mechanical ventilation, presence of tracheotomy, time from of burn injury to BICU admission and initial centre of first emergency treatment was administered. These variables were analysed using univariate and multivariate analysis for the outcomes of death. All patients were scored retrospectively using the five-burn mortality prognostic scores. Predictive ability for burn mortality was analysed using the area under receiver operating curve (AUROC). RESULTS A total of 525 patients (372 males and 153 females) with mean age of 34.5 ± 14.6 years were included. There were 463 survivors and 62 deaths (11.8% mortality rate). The outcome of the primary objective showed that amongst the burn mortality risk factors that remained after multivariate analysis were older age (p = 0.004), wider TBSA burn (p < 0.001) and presence of mechanical ventilation (p < 0.001). Outcome of secondary objective showed good AUROC value for the prediction of burn death for all five burn prediction scores (Baux score; AUROC:0.9, ABSI score; AUROC:0.92, Ryan score; AUROC:0.87, BOBI score; AUROC:0.91 and revised Baux score; AUROC:0.94). The revised Baux score had the best AUROC value of 0.94 to predict burns mortality. CONCLUSION Current study evaluated and identified older age, total body surface area burns, and mechanical ventilation as significant predictors of burn mortality. In addition, the revised Baux score was the most accurate burn mortality risk score to predict mortality in a Malaysian burn's population.

Abstract
BACKGROUND In Spain, the number of aged persons is increasing. By the year 2066, it is expected that 34.6% of the Spanish population will be over 65 years of age. Elderly people present a higher burning risk owing in part to impaired balance and decreased physical strength, lower cognitive abilities, or socioeconomic context. OBJECTIVE Burns to the upper body body are common and affect both emotional state and physical function, thus leading to reduced quality of life (QoL). Our objective was to determine the influence of age on the QoL of patients who experienced burns to the upper body, with burns with 2 years. METHODS This is an observational study with a sample of 58 patients with burns only on the upper body. Patients were divided into two groups: 29 patients of age over 65 years and 29 patients under 65 years; all of them attended the Vall d'Hebron Burn Center, Barcelona, between 2011 and 2014. From the original sample, 45 patients had survived by the time the information was gathered. The QoL of these individuals was evaluated with the Spanish version of the Burn Specific Health Scale. Demographic data (sex, age, total burn surface area [TBSA], burn mechanism, pathological history, length of hospital stay, and rehabilitation duration) were collected. Statistical analysis included parametric and nonparametric tests as appropriate with R3.3.3. RESULTS There were no differences between groups regarding the mechanism of burn, TBSA, length of hospital stay, and the domains of QoL test. High blood pressure, diabetes, and other comorbidities were significantly more common in the elderly group than in the younger group. Eleven patients died in the elderly group and two in the younger group (p=0.012). CONCLUSION As opposed to what could be expected, in this study, there were no significant differences between surviving patients in both age groups in terms of perceived QoL. Nevertheless, mortality after a burn in the upper side of the body was significantly higher in elderly people than in younger people. The present study results do not support the use of different rehabilitation approaches in elderly patients.

Abstract
Burns are tissue injuries caused by high temperature, chemicals or electricity. Severe burns may involve all of the organs and tissues of the human body, leading to a series of pathophysiological processes and even death. The present study reviewed the clinical data of burn patients, including cases of burn-associated death, to provide evidence for the strategy of burn prevention. Basic information from 13,205 inpatients treated between January 1, 2009 and December 31, 2016 was extracted from the database of the Institute of Burn Research at Southwest Hospital (Chongqing, China). After excluding 3,426 inpatients who were not primarily treated for burns, 9,779 patients remained; among them, 68 cases (0.7%) had died as a direct consequence of the burns. Based on baseline data, the mortality rate, total body surface area of the burn (TBSA), age, sex, cause of injury and complications were analysed. In general, males accounted for a higher percentage than female burn patients. Of the patients, 95.54% had a TBSA of <50%, and the rate of mortality of the patients was increased when the TBSA was ≥50%. The major causes of injury were scalds (41.60%), fire (26.92%) and electricity (15.29%), and the majority of victims were 14 years or younger. With improvements in burn treatment technology in recent years, burn patient mortality was significantly reduced. Complications, including multiple organ failure and severe systemic infection, may reduce the survival rate of patients. The major risk factors for death included burns resulting from explosions, as well as shock, age (aged 0-1 or ≥50 years), greater TBSA and full-thickness burn area. With increasing length of stay at the hospital, patient mortality decreased. The renewal of treatment concepts and refined patient management contributed to the shorter LOS and lower mortality in 2015 and 2016.

Abstract
Background Prognostic measures to determine burn mortality are essential in evaluating the severity of individual burn victims. This is an important process of triaging patients with high risk of mortality that may be nursed in the acute care setting. Malaysian burn research is lacking with only one publication identified which describes the epidemiology of burn victims. Therefore, the objective of this study was to go one step further and identify the predictors of burn mortality from a Malaysian burns intensive care unit (BICU) which may be used to triage patients at higher risk of death. Methods This is a retrospective cohort study of all admissions to Hospital Sultan Ismail’s BICU from January 2010 till October 2015. Admission criteria were in accordance with the American Burn Association guidelines, and risk factors of interest were recorded. Data was analyzed using simple logistic regression to determine significant predictors of mortality. Survival analysis with time to death event was performed using the Kaplan-Meier survival curve with log-rank test. Results Through the 6-year period, 393 patients were admitted with a male preponderance of 73.8%. The mean age and length of stay were 35.6 (±15.72) years and 15.3 (±18.91) days. There were 48 mortalities with an overall mortality rate of 12.2%. Significant risk factors identified on simple logistic regression were total body surface area (TBSA) > 20% (p < 0.001), inhalation injury (p < 0.001) and presence of early systemic inflammatory response syndrome (SIRS) (p < 0.001). Survival analysis using Kaplan-Meier survival curve showed similar results with TBSA > 20%, presence of SIRS, mechanical ventilation and inhalation injury which were associated with poorer survival (p < 0.001). Conclusion The predictors of mortality identified in a Malaysian BICU were TBSA > 20%, early SIRS, mechanical ventilation and inhalation injury which were associated with poorer survival outcome. The immunological response differs from individual patients and influenced by the severity of burn injury. Early SIRS on admission is an important predictor of death and may represent the severity of burn injury. Patients who required mechanical ventilation were associated with mortality and it is likely related to the severity of pulmonary insults sustained by individual patients. This data is important for outcome prognostication and mortality risk counselling in severely burned patients.

Abstract
INTRODUCTION Severe burns are often associated with high morbidity and unsatisfactory functional and esthetic outcomes. Over the last two decades, stem cells have generated great hopes for the treatment of numerous conditions including burns. The aim of this systematic review is to evaluate the role of stem cell therapy as a means to promote burn wound healing. METHODS Comprehensive searches in major databases were carried out in March 2017 for articles on stem cell therapy in burn wound healing. In total 2103 articles were identified and screened on the basis of pre-determined inclusion and exclusion criteria. RESULTS Fifteen experimental and two clinical studies were included in the review. The majority of studies reported significant improvement in macroscopic burn wound appearance as well as a trend toward improved microscopic appearance, after stem cell therapy. Other parameters evaluated, such as re-vascularization, collagen formation, level of pro- and anti-inflammatory mediators, apoptosis and cellular infiltrates, yielded heterogeneous results across studies. CONCLUSION Stem cell therapy appears to exert a positive effect in burn wound healing. There is, therefore, justification for continued efforts to evaluate the use of stem cells as an adjunct to first-line therapies in burns.

Abstract
Research over the last 50 years has led to significant improvements in outcomes for burn victims. Advances in infection control, attenuation of the hypermetabolic response, and new improved surgical approaches have led to decreased morbidity and mortality. Early wound excision eliminates the devitalized tissue, which is the main reservoir for pathogen propagation. Immediate autografting reestablishes the natural barrier of the skin, which blocks pathogen access to the host. Advances in burn care have increased treatment options for patients with devastating injuries presenting with multiple comorbidities. Over the last 20 years, negative pressure assisted wound therapy (NPWT) has shown to improve wound management and healing as well as decrease the length of recovery in burn patients. As NPWT applications evolve, the development of negative pressure wound therapy with instillation and dwell time (NPWTi-d) for the management of complex and infected wounds has proven vital for patient care. We present the case of a 68-year-old male patient presenting with a three-day-old third-degree burn wound spanning 46% of the total body surface area (TBSA). After the infected wound was treated unsuccessfully with the standard of care (excision, debridement, and grafting), the team utilized NPWTi-d in order to mitigate the infection and promote the formation of granulation tissue, leading to the successful grafting of the burn wound. NPWTi-d was a useful adjunct in treating and stimulating wound healing in a complex patient. This is the first case report of its kind, utilizing a whole-body vacuum assisted closure (VAC) with NPWTi-d, with successful results showing a decreased bacterial burden, decreased morbidity and mortality, and patient wound closure.

Abstract
INTRODUCTION An investigation into long-term cognitive impairment and Quality of Life (QoL) after severe burns. METHODS A proof of principle, cohort design, prospective, observational clinical study. Patients with severe burns (>15% TBSA) admitted to Burns ICU for invasive ventilation were recruited for psychocognitive assessment with a convenience sample of age and sex-matched controls. Participants completed psychological and QoL questionnaires, the Cogstate® electronic battery, Hopkins Verbal Learning, Verbal Fluency and Trail making tasks. RESULTS 15 patients (11M, 4F; 41±14 years; TBSA 38.4%±18.5) and comparators (11M, 4F; 40±13 years) were recruited. Burns patients reported worse QoL (Neuro-QoL Short Form v2, patient 30.1±8.2, control 38.7±3.2, p=0.0004) and cognitive function (patient composite z-score 0.01, IQR -0.11 to 0.33, control 0.13, IQR 0.47-0.73, p=0.02). Compared to estimated premorbid FSIQ, patients dropped an equivalent of 8 IQ points (p=0.002). Cognitive function negatively correlated with burn severity (rBaux score, p=0.04). QoL strongly correlated with depressive symptoms (Rho=-0.67, p=0.009) but not cognitive function. CONCLUSIONS Severe burns injuries are associated with a significant, global, cognitive deficit. Patients also report worse QoL, depression and post-traumatic stress. Perceived QoL from cognitive impairment was more closely associated with depression than cognitive impairment.

Abstract
Burn injury increases the risk of morbidity and mortality by promoting severe hemodynamic shock and risk for local or systemic infection. Graft failure due to poor wound healing or infection remains a significant problem for burn subjects. The mechanisms by which local burn injury compromises the epithelial antimicrobial barrier function in the burn margin, containing the elements necessary for healing of the burn site, and in distal unburned skin, which serves as potential donor tissue, are largely unknown. The objective of this study was to establish defects in epidermal barrier function in human donor skin and burn margin, to identify potential mechanisms that may lead to graft failure and/or impaired burn wound healing. In this study, we established that epidermal lipids and respective lipid synthesis enzymes were significantly reduced in both donor skin and burn margin. We further identified diverse changes in the gene expression and protein production of several candidate skin antimicrobial peptides (AMPs) in both donor skin and burn margin. These results also parallel changes in cutaneous AMP activity against common burn wound pathogens, aberrant production of epidermal proteases known to regulate barrier permeability and AMP activity, and greater production of proinflammatory cytokines known to be induced by AMPs. These findings suggest that impaired epidermal lipid and AMP regulation could contribute to graft failure and infectious complications in subjects with burn or other traumatic injury.

Abstract
Age, burn size, and inhalation injury are the major contributing variables related to burn mortality. While the female gender has been linked to higher mortality, the impact of socioeconomic status has not been well studied. The interplay between these three factors is also unknown. This study sought to clarify the effects of these variables on outcomes in a national sample of patients with burns. A retrospective review of 172,640 patient records of the National Burn Repository (version 8, 2002-2011) data was conducted. Of those records, 36,960 (21.4%) patient entries were excluded for duplicate entries, follow-up visits, readmissions, nonburn injuries, skin diseases, and incompleteness (missing date of admission, date of discharge, race, or TBSA of burn or TBSA). Univariate and multivariate analyses were performed to compare outcomes by race (Caucasian, African-American, and other minority groups). P < .05 was considered significant. The study group included 135,680 patients and was predominately Caucasian (59.0% Caucasian, 19.0% African-American, and 22.0% other minority groups). The African-American race had more females, operations, longer length of stay, ventilator days, septicemia (all P < .001), and urinary tract infections (UTIs, P < .01). Caucasians had the largest burns (9.27 ± 13.22, P <.001) and were more likely to be older, to be intubated, and to have longer intensive care unit stays and higher mortality (all P < .001). Other non-African-American minorities (other minority group) had the second largest burn sizes, most uninsured members, and lowest mortality (P < .001). On multivariate analysis, mortality was related to African-American race, female gender, TBSA, full-thickness burn injury, inhalation injury, uninsured status, and burn mechanism. African-Americans were 50% more likely to have complications (P < .001), 30% more likely to have UTIs (P = .002), and 41% more likely to get septicemia (P < .001). Other racial minority groups had more acute respiratory distress syndrome, pneumonias, septicemia, UTIs, length of stay, and hospital charges when compared with Caucasian patients. Socioeconomic status was related to mortality but inconsistently related to other outcomes. Race appears to play a significant role in burn injury outcomes. Minority groups, especially African-Americans, have a higher risk of morbidity and mortality compared with Caucasian patients with burns. Socioeconomic status and gender also play a significant role in burn outcomes. Future studies should focus on delineating the reasons for this disparity.

Abstract
Introduction Phosphate level is often deranged during acute illness, regardless of the presence of kidney injury or not. A few studies described that hypophosphatemia may associated with outcome in patients admitted to the burn unit, but the literatures for hyperphosphatemia is limited. Our study aims to evaluate if hyperphosphatemia, one of the sign of severe tissue damage or kidney injury, will associate with mortality of patients with severe burns. Materials and methods The study was a post hoc analysis of prospectively collected data from patients admitted to the burn unit between September 2006 and December 2011. Patients were stratified into normophosphatemic or hyperphosphatemic group by baseline plasma phosphate level. The primary endpoint is 90-day mortality. Results Total 301 patients were included (hyperphosphatemia: n = 52; normophosphatemia: n = 249). The hyperphosphatemic group had lower Glasgow Coma Scale, mean arterial blood pressure, hemoglobin level, albumin, and higher TBSA of burns, APACHE II score, ABSI score, Acute kidney injury (AKI), and creatinine. The 90-day mortality was higher in the hyperphosphatemic group than in the normal group (53.8% vs 18.1%, P < .001) and this difference was still significant when adjusting for several confounding factors (hazard ratio, 2.05; 95% CI, 1.17–3.59). Multivariable Cox analysis showed risk factors of mortality included TBSA of burns, hyperphosphatemia, reduced urine output, and APACHE II score. Conclusions Our study found in addition to TBSA of burns and inhalation injury, baseline hyperphosphatemia in patients with severe burns is also associated with higher mortality.

Targeting bacterial adherence inhibits multidrug-resistant Pseudomonas aeruginosa infection following burn injury. Sci Rep 2016; 6:39341.

Abstract
Classical antimicrobial drugs target proliferation and therefore place microbes under extreme selective pressure to evolve resistance. Alternative drugs that target bacterial virulence without impacting survival directly offer an attractive solution to this problem, but to date few such molecules have been discovered. We previously discovered a widespread group of bacterial adhesins, termed Multivalent Adhesion Molecules (MAMs) that are essential for initial binding of bacteria to host tissues and virulence. Thus, targeting MAM-based adherence is a promising strategy for displacing pathogens from host tissues and inhibiting infection. Here, we show that topical application of polymeric microbeads functionalized with the adhesin MAM7 to a burn infected with multidrug-resistant Pseudomonas aeruginosa substantially decreased bacterial loads in the wound and prevented the spread of the infection into adjacent tissues. As a consequence, the application of this adhesion inhibitor allowed for vascularization and wound healing, and maintained local and systemic inflammatory responses to the burn. We propose that MAM7-functionalized microbeads can be used as a topical treatment, to reduce bacterial attachment and hence prevent bacterial colonization and infection of wounds. As adhesion is not required for microbial survival, this anti-infective strategy has the potential to treat multidrug-resistant infections and limit the emergence of drug-resistant pathogens.
