Evaluation of critical care burden following traumatic injury from two randomized controlled trials. Sci Rep 2023; 13:1106. [PMID: 36670216 PMCID: PMC9860020 DOI: 10.1038/s41598-023-28422-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2022] [Accepted: 01/18/2023] [Indexed: 01/22/2023] Open
Abstract
Trauma resuscitation practices have continued to improve with new advances targeting prehospital interventions. The critical care burden associated with severely injured patients at risk of hemorrhage has been poorly characterized. We aim to describe the individual and additive effects of multiorgan failure (MOF) and nosocomial infection (NI) on delayed mortality and resource utilization. A secondary analysis of harmonized data from two large prehospital randomized controlled trials (Prehospital Air Medical Plasma (PAMPer) Trial and Study of Tranexamic Acid during Air and Ground Medical Prehospital Transport (STAAMP) Trial) was conducted. Only those patients who survived beyond the first 24 hours post-injury and spent at least one day in the ICU were included. Patients were stratified by development of MOF only, NI only, both, or neither and diagnosis of early (≤ 3 days) versus late MOF (> 3 days). Risk factors of NI and MOF, time course of these ICU complications, associated mortality, and hospital resource utilization were evaluated. Of the 869 patients who were enrolled in PAMPer and STAAMP and who met study criteria, 27.4% developed MOF only (n = 238), 10.9% developed NI only (n = 95), and 15.3% were diagnosed with both MOF and NI (n = 133). Patients developing NI and/or MOF compared to those who had an uncomplicated ICU course had greater injury severity, lower GCS, and greater shock indexes. Early MOF occurred in isolation, while late MOF more often followed NI. MOF was associated with 65% higher independent risk of 30-day mortality when adjusting for cofounders (OR 1.65; 95% CI 1.04-2.6; p = 0.03), however NI did not significantly affect odds of mortality. NI was individually associated with longer mechanical ventilation, ICU stay, hospital stay, and rehabilitation requirements, and the addition of MOF further increased the burden of inpatient and post-discharge care. MOF and NI remain common complications for those who survive traumatic injury. MOF is a robust independent predictor of mortality following injury in this cohort, and NI is associated with higher resource utilization. Timing of these ICU complications may reveal differences in pathophysiology and offer targets for continued advancements in treatment.

Characteristics of Prehospital Death in Trauma Victims. J Clin Med 2021; 10:jcm10204765. [PMID: 34682888 PMCID: PMC8540414 DOI: 10.3390/jcm10204765] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Revised: 10/09/2021] [Accepted: 10/11/2021] [Indexed: 12/04/2022] Open
Abstract
Background: Using Injury Severity Score (ISS) data, this study aimed to give an overview of trauma mechanisms, causes of death, injury patterns, and potential survivability in prehospital trauma victims. Methods: Age, gender, trauma mechanism, cause of death, and ISS data were recorded regarding forensic autopsies and whole-body postmortem CT. Characteristics were analyzed for injuries considered potentially survivable at cutoffs of (I) ISS ≤ 75 vs. ISS = 75, (II) ISS ≤ 49 vs. ISS ≥ 50, and (III) ISS < lethal dose 50% (LD50) vs. ISS > LD50 according to Bull’s probit model. Results: In n = 130 prehospital trauma victims (45.3 ± 19.5 years), median ISS was 66. Severity of injuries to the head/neck and chest was greater compared to other regions (p < 0.001). 52% died from central nervous system (CNS) injury. Increasing injury severity in head/neck region was associated with CNS-injury related death (odds ratio (OR) 2.7, confidence interval (CI) 1.8–4.4). Potentially survivable trauma was identified in (I) 56%, (II) 22%, and (III) 9%. Victims with ISS ≤ 75, ISS ≤ 49, and ISS < LD50 had lower injury severity across most ISS body regions compared to their respective counterparts (p < 0.05). Conclusion: In prehospital trauma victims, injury severity is high. Lethal injuries predominate in the head/neck and chest regions and are associated with CNS-related death. The appreciable amount (9–56%) of victims dying at presumably survivable injury severity encourages perpetual efforts for improvement in the rescue of highly traumatized patients.

Abstract
Background Thoracic trauma is a relevant source of comorbidity throughout multiply-injured patient care. We aim to determine a measurable influence of chest trauma’s severity on early resuscitation, intensive care therapy, and mortality in severely injured patients. Methods Patients documented between 2002 and 2012 in the TraumaRegister DGU®, aged ≥ 16 years, injury severity score (ISS) ≥ 16 are analyzed. Isolated brain injury and severe head injury led to exclusion. Subgroups are formed using the Abbreviated Injury ScaleThorax. Results Twenty-two thousand five hundred sixty-five patients were predominantly male (74%) with mean age of 45.7 years (SD 19.3), blunt trauma (95%), mean ISS 25.6 (SD 9.6). Overall mean intubation period was 5.6 days (SD 10.7). Surviving patients were discharged from the ICU after a mean of about 5 days following extubation. Thoracic trauma severity (AISThorax ≥ 4) and fractures to the thoracic cage significantly prolonged the ventilation period. Additionally, fractures extended the ICU stay significantly. Suffering from more than one thoracic injury was associated with a mean of 1–2 days longer intubation period and longer ICU stay. Highest rates of sepsis, respiratory, and multiple organ failure occurred in patients with critical compared to lesser thoracic trauma severity. Conclusion Thoracic trauma severity in multiply-injured patients has a measurable impact on rates of respiratory and multiple organ failure, sepsis, mortality, time of mechanical ventilation, and ICU stay.

Abstract
The development of organ dysfunction (OD) is related to the intensity and balance between trauma-induced simultaneous, opposite inflammatory responses. Early proinflammation via innate immune system activation may cause early OD, whereas antiinflammation, via inhibition of the adaptive immune system and apoptosis, may induce immunoparalysis, impaired healing, infections, and late OD. Patients discharged with low-level OD may develop the persistent inflammation-immunosuppression catabolism syndrome. Although the incidence of multiple organ failure has decreased over time, it remains morbid, lethal, and resource intensive. However, single OD, especially acute lung injury, remains frequent. Treatment is limited, and prevention remains the mainstay strategy.

Abstract
BACKGROUND Acute myocardial infarction (AMI) can be complicated by multiple organ dysfunction syndrome (MODS), but the exact influence of MODS on AMI remains unclear. METHODS This was a retrospective study of 6674 Chinese patients with AMI. The impact of MODS was assessed using the Cox proportional hazard model. Using the occurrence of MODS as the outcome, a prediction model was developed using the factors identified by logistic regression analysis and analyzed using receiving operator characteristic curves. RESULTS Of 6674 patients with AMI, 83 (1.2%) progressed to MODS. MODS independently predicted the risk of 30-day in-hospital mortality [hazard ratio, 2.3; 95% confidence interval (95% CI), 1.7-3.2; P<0.001]. Advanced age [odds ratio (OR), 2.76; 95% CI, 1.26-6.03; P=0.011 for age 65-74 years; OR, 4.85; 95% CI, 2.96-7.93; P<0.001 for age ≥75 years), pneumonia (OR, 4.27; 95% CI, 2.68-6.81; P<0.001), and chronic renal failure (OR, 2.09; 95% CI, 1.09-4.01; P=0.027) were associated independently with MODS. The area under the receiving operator characteristic curve for the predictive model was 0.802, indicating a good predictive value. CONCLUSION MODS can predict the worst severity of AMI. Using common clinical variables, it is possible to identify patients with AMI who are at high risk of MODS. Additional studies are necessary to confirm this model.

Abstract
Trauma still represents one of the major causes of death worldwide. Despite the reduction of post-traumatic sepsis over the past two decades, the mortality of septic trauma inpatients is still high (19.5-23 %). Early prevention of sepsis development can aid in the subsequent treatment of patients and help improve their outcomes. To date, the prevention of trauma-related infection/sepsis has mainly included infection prevention (e.g., surgical management, prophylactic antibiotics, tetanus vaccination, immunomodulatory interventions) and organ dysfunction prevention (e.g., pharmaceuticals, temporary intravascular shunts, lung-protective strategies, enteral immunonutrition, acupuncture). Overall, more efficient ways should be developed to prevent trauma-related infection/sepsis.

Abstract
The standard treatment for acute respiratory distress syndrome (ARDS) is supportive in the form of low tidal volume ventilation applied after significant lung injury has already developed. Nevertheless, ARDS mortality remains unacceptably high (> 40%). Indeed, once ARDS is established it becomes refractory to treatment, and therefore avoidance is key. However, preventive techniques and therapeutics to reduce the incidence of ARDS in patients at high-risk have not been validated clinically. This review discusses the current data suggesting that preemptive application of the properly adjusted mechanical breath can block progressive acute lung injury and significantly reduce the occurrence of ARDS.

Abstract
Multiple organ failure is the leading cause of death in patients with severe multiple trauma in the early stage after injury. Hepatic insufficiency is common in intensive care unit (ICU), and about 27% of the patients with severe trauma suffer hepatic failure. However, the pathogenesis of traumatic liver damage is complicated due to the following main reasons: liver trauma, ischemia-reperfusion injury, severe sepsis, danger associated molecular patterns and so on. Clinically, trauma-induced liver injury can be managed conservatively or surgically, therefore, clarifying the mechanisms of traumatic liver damage, finding a new therapeutic target and improving its diagnosis and treatment are very important. This paper reviews the mechanism of post-traumatic liver injury and its diagnosis and treatment.

Abstract
BACKGROUND The aim of this study was to investigate the influence of the surgical timing in patients with pelvic fractures and severe chest trauma on the clinical course, especially on postoperative lung function. METHODS A total of 47 patients were included in a prospective dual observational study. The study investigated the clinical course depending on the time of operation based on the functional lung parameters, SAPS II, SOFA and total hospital stay. RESULTS The average ISS was 32±6, PTS was 34±11 and TTSS was 9±3 points. The pelvic fractures were stabilized definitively after an average of 7±2 days. The early stabilization correlated significantly with a lower TTSS and SAPS II on admission (p<0.05), shorter time of ventilation (p<0.05) and stay in the intensive care unit (p<0.01) as well as the decreased need for packed red blood cells (p<0.01). CONCLUSIONS In this study patients with pelvic fractures and thoracic trauma benefited positively from an earlier definitive pelvic fracture stabilization with respect to a shorter time of ventilation and stay in the intensive care unit due to a lower need for red cell concentrates.

Abstract
BACKGROUND In the severely injured who survive the early posttraumatic phase, multiple-organ failure (MOF) is the main cause of morbidity and mortality. An enhanced prediction of MOF might influence individual monitoring and therapy of severely injured patients. METHODS We performed a retrospective analysis of a nationwide prospective database, the TraumaRegister DGU of the German Trauma Society. Patients with complete data sets (2002-2011) and a relevant trauma load (Injury Severity Score [ISS] ≥ 16), who were admitted to an intensive care unit, were included. RESULTS Of a total of 31,154 patients enclosed in this study, 10,201 (32.7%) developed an MOF according to the Sequential Organ Failure Assessment score. During the study period, mortality of all patients decreased from 18.1% in 2002 to 15.3% in 2011 (p < 0.001). Meanwhile, MOF occurred significantly more often (24.6% in 2002 vs. 31.5% in 2011, p < 0.001), but mortality of MOF patients decreased (42.6% vs. 33.3%, p < 0.001). MOF patients who died survived 2 days less (11 days in 2002 vs. 8.9 days in 2011, p < 0.001). Independent risk factors for the development of MOF following severe trauma were age, ISS, head Abbreviated Injury Scale (AIS) score of 3 or higher, thoracic AIS score of 3 or higher, male sex, Glasgow Coma Scale (GCS) score of 8 or less, mass transfusion, base excess of less than -3, systolic blood pressure less than 90 mm Hg at admission, and coagulopathy. CONCLUSION Over one decade, we observed an ongoing decrease of mortality after multiple trauma, accompanied by decreasing mortality in the subgroup with MOF. However, incidence of MOF in the severely injured increased significantly. Thus, MOF after multiple trauma remains a challenge in intensive care. The risk factors from multivariate analysis could be instrumental in anticipating the early development of MOF. Furthermore, a reliable prediction model might be supportive for patient enrolment in trauma studies, in which MOF marks the primary end point. LEVEL OF EVIDENCE Epidemiologic study, level III.

Abstract
BACKGROUND While the incidence of postinjury multiple-organ failure (MOF) has declined during the past decade, temporal trends of its morbidity, mortality, presentation patterns, and health care resources use have been inconsistent. The purpose of this study was to describe the evolving epidemiology of postinjury MOF from 2003 to 2010 in multiple trauma centers sharing standard treatment protocols. METHODS "Inflammation and Host Response to Injury Collaborative Program" institutions that enrolled more than 20 eligible patients per biennial during the 2003 to 2010 study period were included. The patients were aged 16 years to 90 years, sustained blunt torso trauma with hemorrhagic shock (systolic blood pressure < 90 mm Hg, base deficit ≥ 6 mEq/L, blood transfusion within the first 12 hours), but without severe head injury (motor Glasgow Coma Scale [GCS] score < 4). MOF temporal trends (Denver MOF score > 3) were adjusted for admission risk factors (age, sex, body max index, Injury Severity Score [ISS], systolic blood pressure, and base deficit) using survival analysis. RESULTS A total of 1,643 patients from four institutions were evaluated. MOF incidence decreased over time (from 17% in 2003-2004 to 9.8% in 2009-2010). MOF-related death rate (33% in 2003-2004 to 36% in 2009-2010), intensive care unit stay, and mechanical ventilation duration did not change over the study period. Adjustment for admission risk factors confirmed the crude trends. MOF patients required much longer ventilation and intensive care unit stay, compared with non-MOF patients. Most of the MOF-related deaths occurred within 2 days of the MOF diagnosis. Lung and cardiac dysfunctions became less frequent (57.6% to 50.8%, 20.9% to 12.5%, respectively), but kidney and liver failure rates did not change (10.1% to 12.5%, 15.2% to 14.1%). CONCLUSION Postinjury MOF remains a resource-intensive, morbid, and lethal condition. Lung injury is an enduring challenge and should be a research priority. The lack of outcome improvements suggests that reversing MOF is difficult and prevention is still the best strategy. LEVEL OF EVIDENCE Epidemiologic study, level III.

Abstract
BACKGROUND Severe trauma is characterized by a pronounced immunologic response with both proinflammatory and anti-inflammatory characteristics. The clinical course of trauma patients is often complicated by late-onset (>5 days) sepsis. However, the underlying mechanisms remain poorly defined. Here we studied the kinetics of systemic activation of neutrophils and monocytes following injury in trauma patients in the context of development of sepsis. METHODS Thirty-six severely injured patients were included and followed up for 10 days in the intensive care unit. Serial blood samples were taken daily and analyzed ex vivo for activation of PMNs (polymorphonuclear leukocytes, i.e., neutrophils) (expression MAC-1 [macrophage-1 antigen], CXCR-1 [CXC-chemokine receptor 1], FcγRII) and expression of human leukocyte antigen DR (HLA-DR) on monocytes. In addition, the functionality of PMNs was measured by activation of the respiratory burst and responsiveness for the innate immune stimulus N-formyl-methionyl-leucyl-phenylalanine (fMLF). RESULTS Ten of 36 patients developed septic shock, invariably 8 to 10 days after admission. CXCR-1 and fMLF-induced active FcγRII showed a gradual decrease in expression before clinical signs of septic shock. Patients who developed septic shock demonstrated a statistically significantly decreased fMLF-induced active FcγRII (P = 0.009) at initial presentation. An immediate decreased percentage of HLA-DR-positive monocytes could be contributed to an increased absolute number of HLA-DR-negative monocytes. CONCLUSIONS Phenotyping blood PMNs enables identification of the kinetics and magnitude of the initial systemic inflammatory response after injury. The decreased functionality of PMNs and monocytes reaches its minimum before the development of sepsis and could be an important contributing factor. This could support the early identification of patients at risk.

Abstract
BACKGROUND Adult respiratory distress syndrome is often refractory to treatment and develops after entering the health care system. This suggests an opportunity to prevent this syndrome before it develops. The objective of this study was to demonstrate that early application of airway pressure release ventilation in high-risk trauma patients reduces hospital mortality as compared with similarly injured patients on conventional ventilation. METHODS Systematic review of observational data in patients who received conventional ventilation in other trauma centers were compared with patients treated with early airway pressure release ventilation in our trauma center. Relevant studies were identified in a PubMed and MEDLINE search from 1995 to 2012 and included prospective and retrospective observational and cohort studies enrolling 100 or more adult trauma patients with reported adult respiratory distress syndrome incidence and mortality data. RESULTS Early airway pressure release ventilation as compared with the other trauma centers represented lower mean adult respiratory distress syndrome incidence (14.0% vs. 1.3%) and in-hospital mortality (14.1% vs. 3.9%). CONCLUSION These data suggest that early airway pressure release ventilation may prevent progression of acute lung injury in high-risk trauma patients, reducing trauma-related adult respiratory distress syndrome mortality.

Abstract
BACKGROUND Recent innovations in care have improved survival following injury. Coincidentally, the population of elderly injured patients with preexisting comorbidities has increased. We hypothesized that this increase in elderly injured patients may have combined with recent care innovations to alter the causes of death after trauma. METHODS We reviewed demographics, injury characteristics, and cause of death of in-hospital deaths of patients admitted to our Level I trauma service from 2000 through 2011. Cause of death was classified as acute hemorrhagic shock; severe traumatic brain injury or high spinal cord injury; complications of preexisting medical condition only (PM); survivable trauma combined with complications of preexisting medical condition (TCoM); multiple-organ failure, sepsis, or adult respiratory distress syndrome (MOF/S/ARDS), or trauma not otherwise categorized (e.g., asphyxiation). Major trauma care advances implemented on our service during the period were identified, and trends in the causes of death were analyzed. RESULTS Of the 27,276 admissions, 819 (3%) eligible nonsurvivors were identified for the cause-of-death analyses. Causes of death were severe traumatic brain injury or high spinal cord injury at 44%, acute hemorrhagic shock at 28%, PM at 11%, TCoM at 10%, MOF/S/ARDS at 2%, and trauma not otherwise categorized at 5%. Mean age at death increased across the study interval (range, 47-57 years), while mean Injury Severity Score (ISS) decreased (range, 28-35). There was a significant increase in deaths because of TCoM (3.3-20.9%) and PM (6.7-16.4%), while deaths caused by MOF/S/ARDS decreased from 5% to 0% by 2007. Compared with year 2000, the annual adjusted mortality rate decreased consistently starting in 2009, after the 2002 to 2007 adoption of four major trauma practice guidelines. CONCLUSION Mortality caused by preexisting medical conditions has increased, while markedly fewer deaths resulted from the complications of injury. Future improvements in outcomes will require improvement in the management of elderly trauma patients with comorbid conditions.

Abstract
BACKGROUND Critically-ill trauma patients have a high mortality. OBJECTIVE To study the factors affecting the mortality of ICU trauma patients treated at Al-Ain Hospital, United Arab Emirates (UAE). METHODS All trauma patients who were admitted to the ICU were prospectively collected over three years (2003-2006). Univariate and multivariate analysis were used to compare patients who died and who did not. Gender, age, nationality, mechanism of injury, systolic blood pressure and GCS on arrival, the need for ventilation, presence of head or chest injuries, AIS for the chest and head injuries and the ISS were studied. RESULTS There were 202 patients (181 males). The most common mechanism of injury was road traffic collisions (72.3 %). The overall mortality was 13.9%. A direct logistic regression model has shown that factors that affected mortality were decreased GCS (p < 0.0001), mechanism of injury (p = 0.004) with burns having the highest mortality, increased age (p = 0.004), and increased ISS (p = 0.02). The best GCS that predicted mortality was 5.5 while the best ISS that predicted mortality was 13.5. CONCLUSION Road traffic collision is the most common cause of serious trauma in UAE followed by falls. Decreased GCS was the most significant factor that predicted mortality in the ICU trauma patients.

Abstract
BACKGROUND The incidence of pulmonary failure in trauma patients is considered to be influenced by several factors such as liver injury. We intended to assess the association of various potential predictors of pulmonary failure following thoracic trauma and liver injury. METHODS Records of 12,585 trauma patients documented in the TraumaRegister DGU® of the German Trauma Society were analyzed regarding the potential impact of concomitant liver injury on the incidence of pulmonary failure using uni- and multivariate analyses. Pulmonary failure was defined as pulmonary failure of ≥ 3 SOFA-score points for at least two days. Patients were subdivided according to their injury pattern into four groups: group 1: AIS thorax < 3; AIS liver < 3; group 2: AIS thorax ≥ 3; AIS liver < 3; group 3: AIS thorax < 3; AIS liver ≥ 3 and group 4: AIS thorax ≥ 3; AIS liver ≥ 3. RESULTS Overall, 2643 (21%) developed pulmonary failure, 12% (n= 642) in group 1, 26% (n= 697) in group 2, 16% (n= 30) in group 3, and 36% (n= 188) in group 4. Factors independently associated with pulmonary failure included relevant lung injury, pre-existing medical conditions (PMC), sex, transfusion of more than 10 units of packed red blood cells (PRBC), Glasgow Coma Scale (GCS) ≤ 8, and the ISS. However, liver injury was not associated with an increased risk of pulmonary failure following severe trauma in our setting. CONCLUSIONS Specific factors, but not liver injury, were associated with an increased risk of pulmonary failure following trauma. Trauma surgeons should be aware of these factors for optimized intensive care treatment.

Abstract
OBJECTIVE Identify the factors of greatest impact in patients with chest trauma. PATIENTS AND METHODS prospective study of 500 patients (425 men and 75 women) with chest trauma treated between January 2006 and December 2008. The parameters assessed include the degree of trauma, the abbreviated injury scale (AIS), the injury severity score (ISS), pre-hospital intubation, duration of mechanical ventilation, stay in the intensive care unit (ICU), number of rib fractures, presence of pulmonary contusion, haemothorax and cardio-pulmonary effects. RESULTS The presence of polytrauma, the number of rib fractures, the presence of flail chest, pulmonary contusion, the delay in mechanical ventilation and age were shown to be effective markers of severity. CONCLUSIONS Thoracic injuries have a number of indicators of severity. The mortality risk is associated with an ISS >25, the presence of 3 or more rib fractures with flail chest, pulmonary contusion, the development of ARDS, and with an age >55 years.

Abstract
OBJECTIVE Open lung and low tidal volume ventilation appear to be a promising ventilation for chest trauma as it can reduce ARDS and improve outcome. Local therapy (e.g. BAL) can be synergic to remove from the lung the debris, mitigate inflammatory cascade and avoid damage spreading to not compromised lung areas. MATERIALS AND METHODS 44 pulmonary contused patients were randomized to receive broncho-suction and volume controlled low tidal volume ventilation-VCLTVV (Control Group) or the same ventilation plus medicated (saline + surfactant) BAL (Treatment Group). Tidal volume <10 ml/kg, PEEP of 10-12 cm H(2)O and PaO(2) 60-100 mm Hg and PaCO(2) 35-45 mm Hg were used in both groups. BAL was performed using a fiberscope. 4 boluses of 25 ml saline with 2.4 mg/ml of surfactant were introduced into each contused lobe in which, subsequently, 240 mg of surfactant was instilled. RESULTS All patients survived. In the Control Group 18 patients developed pneumonia, 5 ARDS and days of intubation were 11.50 (3.83) compared to 5.05 (1.21) of Treatment Group in which OI and PaO(2)/FiO(2) significantly improved from 36 h. CONCLUSIONS VCLTVV alone was not able to prevent ARDS and infection in the Control Group as the reduction of intubation. In the Treatment Group, VCLTVV and medicated BAL facilitated the removal of degradated lung material and recruited the contused lung regions, enabling the healing of the lung pathology.

Modulation of the innate immune response after trauma visualised by a change in functional PMN phenotype. Injury 2009; 40:851-5.

Abstract
BACKGROUND Acute Respiratory Distress Syndrome (ARDS) is a frequent and severe complication after trauma, caused by an excessive inflammatory response mediated by polymorphonuclear granulocytes (PMNs). It was previously demonstrated that patients with activated PMNs in the lungs have PMNs in the peripheral circulation with a reduced active FcgammaRII up-regulating capacity. We tested the hypothesis that a correlation exists between the severity of inflammation and the extent of decreased responsiveness of active FcgammaRII on circulating PMNs, as a sign of altered immunological capacity. METHODS Fifty-two patients were included and injury severity was assessed by clinical injury severity scores and base deficit. Symptoms and signs of inflammation were recorded on a daily basis and fMLP-induced active FcgammaRII on PMNs was assessed by FACS analysis within 24h after injury. Results were compared with 10, age matched healthy controls. RESULTS The baseline PMN membrane expression of Mac-1/CD11b and active FcgammaRII/CD32 did not correlate with injury severity. Levels of the acute phase protein Interleukin 6 (IL-6) correlated significantly with injury severity, indicating that a range in severity of the inflammatory response was present in the studied population. A statistically significant correlation between the PMN responsiveness towards the bacterial derived peptide fMLP of active FcgammaRII and injury severity was demonstrated. In addition, decreasing responsiveness of active FcgammaRII on PMNs was found in patients who developed systemic inflammatory response syndrome (SIRS) or acute lung injury (ALI)/ARDS. CONCLUSIONS The extent of the sustained injury and the subsequent cellular innate immune response is reflected by changes in a functional PMN phenotype of fMLP-induced active FcgammaRII in the peripheral blood.

Abstract
Most multiple organ failure (MOF) scores were developed over a decade ago, but little has been done in terms of validation and to understand the differences between populations identified by each of them. Given the lack of a gold standard, validation must rely on association with objective adverse outcomes. Thus, we propose to (a) validate two widely accepted MOF scores (Denver and Marshall), examining their association with adverse outcomes in a postinjury population; and (b) compare risk factors, characteristics, and outcomes of patients identified by each score. The Denver MOF score grades (from 0-3) four organ dysfunctions (lung, kidney, liver, and heart) and defines MOF as a total score more than 3. The Marshall score grades, in addition, central nervous system and hematologic dysfunction (total of six organs on a 0- to 4-point scale). Using a prospectively collected data set, MOF was scored daily by both scores for 1,389 consecutive trauma patients with Injury Severity Score of more than 15 admitted from 1992 to 2004. Risk factors, clinical outcomes (death, ventilator-free days), and resource utilization outcomes (mechanical ventilation time, length of stay in the intensive care unit) were evaluated. Both scores were associated with areas under the receiver operating characteristic curves of 80 or greater (ideal value = 100), with values for the Denver score being slightly greater (albeit not significantly) regarding prediction of most outcomes. Values of sensitivity and specificity were more than 70% for death and ventilator-free days (with the Denver score showing a consistent trend toward greater specificity), but either sensitivity or specificity was less than 70% for mechanical ventilation time and length of stay in the intensive care unit, suggesting that these scores are appropriately biased toward clinical outcomes as opposed to resource utilization. Both scores performed well, with the Denver MOF score showing greater specificity, which, coupled with its simplicity, makes it an attractive tool for both the research and clinical environments. Basic concepts of each score can probably be combined to produce an improved MOF score.

Abstract
AIM Determining the characteristics and outcomes of multiple organ dysfunction syndrome (MODS) in severe-burn patients. METHOD A prospective study was conducted in 117 severe-burn, adult patients admitted to the National Institute of Burns, Hanoi, Vietnam with burn area > or =40% of the total body surface area. The diagnosis of MODS was based on Sequential Organ Failure Assessment (SOFA) score. RESULTS MODS was recorded in 45.3% of the patients. A higher rate of MODS was recorded in patients over 40 years of age (51.61%), those presenting with inhalation injury (60.37%) and having a large burn surface area. MODS was commonly seen in the second week after-burn (75.47%). Respiratory system failure was the most common (44.44%), followed by circulatory system failure (41.88%) and failure of other systems. MODS was more common among patients developing sepsis and septic shock (69.64% and 87.5%, respectively). The mortality rate was 86.79% among MODS patients and higher in case of SOFA score > or =6. In addition, mortality rate was 22.22% if one organ was involved, 40% for two organs, 93.33% for three organs and 100% if four or more organs were involved. The durations of artificial ventilation, hospitalisation and intensive care unit stay were significant higher than in MODS patients as compared to non-MODS patients. CONCLUSION MODS is still a severe complication, leading to death after-burn. It is important to identify the risk factors and prevention methods to increase the chances of saving severely burned patients.

Abstract
BACKGROUND Acute lung injury (ALI) is a frequent but poorly understood complication of traumatic brain injury (TBI). The Nrf2-ARE pathway has been proved to be essential for protection against diffuse inflammation and oxidative damage, which are both involved in ALI following TBI. However, whether the Nrf2-ARE pathway is activated after TBI in the lung hasn't been studied. METHODS AND PROCEDURES In the present study, the nuclear Nrf2 protein level was detected by Western blot and the mRNA levels of heme oxygenase-1 (HO-1) and NAD(P)H:quinone oxidoreductase-1 (NQO1), two Nrf2-regulated gene products, were determined by RT-PCR at 24 hours after TBI. In addition, the expression of Nrf2 and HO-1 was localized by immunohistochemical study. MAIN OUTCOMES AND RESULTS After TBI, the nuclear Nrf2 protein level in the lung was significantly increased and the mRNA levels of both HO-1 and NQO1 were also up-regulated. Moreover, immunohistochemical study showed that both Nrf2 and HO-1 were mainly localized in tracheobronchial epithelium and alveolar macrophages. CONCLUSION These results suggest that the Nrf2-ARE pathway is activated in the lung after TBI.

Abstract
The acute and early phase of polytrauma management is decisive for determining and implementing priority-based operative strategy. The patient's general condition and pattern of injury have to be considered. The highest priorities in the acute phase of operative treatment are control of mass bleeding and the release of body cavities (life-saving surgery). In the primary phase of surgical management (day 1 surgery), selected injuries are treated in the order of their urgency. Conceptual damage control surgery is distinguished from early total care. Damage control surgery should be performed only in patients meeting certain instability and risk criteria to avoid additionally burdening their condition.
