Abstract
INTRODUCTION Male urethral injuries are uncommon, and the ideal timing of the definitive treatment remains controversial. This study aimed to compare the outcomes of early and delayed interventions (1 month or more after the injury) for male urethral injuries. PATIENT AND METHODS We conducted a retrospective review of the medical records of 67 male patients with urethral injuries treated at our institution between 2011 and 2020. We examined patient age, injury severity score (ISS), abbreviated injury scale, mechanism, location and severity of injury, presence of pelvic fractures, surgical interventions, timing of treatment, and complications. We analysed factors associated with urinary complications based on the location of urethral injury. Additionally, we performed a subset analysis of patients with severe injuries (ISS≥16) to assess the impact of delayed surgery. RESULTS Overall, 47 %, 37 %, and 27 % of patients in the delayed treatment group (N = 30) had urethral stricture (US), erectile dysfunction (ED), and/or urinary incontinence (UI). These rates were greater than the 22 % US, 3 % ED, and 11 % UI rates in the early treatment group (N = 37). The subgroup analysis revealed that patients with anterior urethral injury (AUI) who underwent delayed treatment (N = 18) tended to be more severely injured (ISS, 19 vs 9, p = 0.003) and exhibited higher rates of US (44% vs 21 %, p = 0.193) and ED (39% vs 0 %, p = 0.002) than those who received early treatment (N = 24). In the case of posterior urethral injury (PUI), the delayed treatment group (N = 13) had higher rates of US (50% vs 23 %, p = 0.326), ED (33% vs 8 %, p = 0.272), and UI (42% vs 0 %, p = 0.030) than the early treatment group. Regarding study limitations, more than 45 % of the enrolled patients were severely injured (ISS≥16), which may have potentially influenced the timing of urethral injury repair. CONCLUSIONS The treatment of male urethral injuries may be delayed due to concurrent polytrauma and other associated injuries. However, delayed treatment is associated with higher rates of urinary complications. Early treatment of urethral injuries may be beneficial to male patients with urethral trauma, even in cases of severe injury.

Abstract
Trauma-induced coagulopathy (TIC) is a leading contributor to preventable mortality in severely injured patients. Understanding the molecular drivers of TIC is an essential step in identifying novel therapeutics to reduce morbidity and mortality. This study investigated multiomics and viscoelastic responses to polytrauma using our novel swine model and compared these findings with severely injured patients. Molecular signatures of TIC were significantly associated with perturbed coagulation and inflammation systems as well as extensive hemolysis. These results were consistent with patterns observed in trauma patients who had multisystem injuries. Here, intervention using resuscitative endovascular balloon occlusion of the aorta following polytrauma in our swine model revealed distinct multiomics alterations as a function of placement location. Aortic balloon placement in zone-1 worsened ischemic damage and mitochondrial dysfunction, patterns that continued throughout the monitored time course. While placement in zone-III showed a beneficial effect on TIC, it showed an improvement in effective coagulation. Taken together, this study highlights the translational relevance of our polytrauma swine model for investigating therapeutic interventions to correct TIC in patients.

Abstract
Sepsis as a severe systemic inflammation leads oftentimes to organ dysfunction and subsequently to death. In polytrauma patients, septic complications represent with 45% the predominant cause of late death and are responsible for extremely high costs in the healthcare system. Therefore, clinicians have to detect as early as possible the begin of sepsis to improve the patient's outcome. One new promising diagnostic tool to diagnose septic complications in polytraumatized patients are exosomes. Plasma samples from polytraumatized patients (Injury Severity Score (ISS) ≥16) which developed sepsis (n = 10) and without sepsis (n = 10), were collected at emergency room (ER), 24h and 5 days after trauma. The EVs subpopulations were investigated by a bead-based multiplex flow cytometry measurement of surface epitopes and were compared with plasma EVs from healthy controls (n = 10). Moreover, exosomal cytokine concentrations were measured via high-sensitive ELISA and were correlated with systemic concentrations. For miRNA cargo analysis, we analysed the miRNAs miR-1298-5p, miR-1262, miR-125b-5p, miR-92a-3p, miR-93-5p, miR-155-5p and miR-21-5p and compared their exosomal concentrations by means of RT-qPCR. CD62p + exosomes were significantly increased in septic polytrauma-patients (p ≤ 0.05), while CD40+exosomes, as well as CD49e + exosomes were diminished (p ≤ 0.05). Furthermore, we observed that the exosomal IL-6 concentration reflects the systemic IL-6 concentration (r2 = 0.63) and did not significantly alter between patients with and without sepsis. The exosomal IL-10 concentration seemed to be constant in all patients and healthy controls. We observed that a decrease of miR-21-5p in exosomes was associated with the development of sepsis (p ≤ 0.05), while exosomal miR-93-5p, miR-155-5p and miR-92a-3p were not specifically altered in septic patients. Taken together, the present study in polytraumatized patients demonstrated that the development of sepsis is associated with an increase of CD62p + exosomes. Furthermore, the exosomal cargo was changed in septic patients: miR-21-5p was diminished.

Abstract
INTRODUCTION This study aims to analyze the clinical characteristics, demographic features, and injury circumstances of patients admitted to the Emergency Department (ED) at Fondazione Policlinico Universitario A. Gemelli (IRCCS) in Rome, Italy, due to bicycle accidents. METHODS Data on clinical characteristics, accident timing, injury circumstances, and helmet use were collected for ED patients involved in bicycle accidents from January 2019 to December 2022. Subsequently, Abbreviated Injury Scale codes of all diagnoses were recorded and the Injury Severity Score was calculated. RESULTS Over the study period, 763 patients were admitted to the ED following bicycle accidents, with a 0.3 % fatality rate and a 30.4 % frequency of multitrauma. Multivariate analysis revealed that collisions with other vehicles increased trauma severity and the risk of ICU admission. Conversely, helmet use was associated with reduced severity of head trauma and a lower likelihood of ICU admission. Notably, toxicological investigations were not conducted for any ED-admitted patients. CONCLUSIONS Although a low mortality rate and a low incidence of multi-trauma have been shown in comparison to other nations, it is necessary to adopt prevention strategies like safety devices, more cycle paths, and better infrastructures on the one hand, and stricter laws on the other. It is essential to require toxicological testing in Italy for all accidents involving this means of transport, and to make helmet use compulsory for all ages.

Abstract
INTRODUCTION Fluid resuscitation has long been a cornerstone of pre-hospital trauma care, yet its optimal approach remains undetermined. Although a liberal approach to fluid resuscitation has been linked with increased complications, the potential survival benefits of a restrictive approach in blunt trauma patients have not been definitively established. Consequently, equipoise persists regarding the optimal fluid resuscitation strategy in this population. METHODS We analysed data from the two largest European trauma registries, the UK Trauma Audit and Research Network (TARN) and the German TraumaRegister DGU® (TR-DGU), between 2004 and 2018. All adult blunt trauma patients with an Injury Severity Score > 15 were included. We examined annual trends in pre-hospital fluid resuscitation, admission coagulation function, and mortality rates. RESULTS Over the 15-year study period, data from 68,510 patients in the TARN cohort and 82,551 patients in the TR-DGU cohort were analysed. In the TARN cohort, 3.4% patients received pre-hospital crystalloid fluids, with a median volume of 25 ml (20-36 ml) administered. Conversely, in the TR-DGU cohort, 91.1% patients received pre-hospital crystalloid fluids, with a median volume of 756 ml (750-912 ml) administered. Notably, both cohorts demonstrated a consistent year-on-year decrease in the volume of pre-hospital fluid administered, accompanied by improvements in admission coagulation function and reduced mortality rates. CONCLUSION Considerable variability exists in pre-hospital fluid resuscitation strategies for blunt trauma patients. Our data suggest a trend towards reduced pre-hospital fluid administration over time. This trend appears to be associated with improved coagulation function and decreased mortality rates. However, we acknowledge that these outcomes are influenced by multiple factors, including other improvements in pre-hospital care over time. Future research should aim to identify which trauma populations may benefit, be harmed, or remain unaffected by different pre-hospital fluid resuscitation strategies.

Abstract
BACKGROUND Occult hypoperfusion describes the absence of sufficient microcirculation despite normal vital signs. It is known to be associated with prolonged elevation of serum lactate and later complications in severely injured patients. We hypothesized that changes in circulating lipids are related to responsiveness to resuscitation. The purpose of this study is investigating the relation between responsiveness to resuscitation and lipidomic course after poly trauma. METHODS Twenty-five male pigs were exposed a combined injury of blunt chest trauma, liver laceration, controlled haemorrhagic shock, and femoral shaft fracture. After 1 h, animals received resuscitation and fracture stabilization. Venous blood was taken regularly and 233 specific lipids were analysed. Animals were divided into two groups based on serum lactate level at the end point as an indicator of responsiveness to resuscitation (<2 mmol/L: responder group (R group), ≧2 mmol/L: occult hypoperfusion group (OH group)). RESULTS Eighteen animals met criteria for the R group, four animals for the OH group, and three animals died. Acylcarnitines showed a significant increase at 1 h compared to baseline in both groups. Six lipid subgroups showed a significant increase only in R group at 2 h. There was no significant change at other time points. CONCLUSIONS Six lipid groups increased significantly only in the R group at 2 h, which may support the idea that they could serve as potential biomarkers to help us to detect the presence of occult hypoperfusion and insufficient resuscitation. We feel that further study is required to confirm the role and mechanism of lipid changes after trauma.

Abstract
BACKGROUND Immunological disorder remains a great challenge in severe poly-trauma, in which lymphopenia is an important contributor. The purpose of present study is to explore whether ferroptosis, a new manner of programmed cell death (PCD), is involved in the lymphocyte depletion and predictive to the adverse prognosis of severe injuries. PATIENTS AND METHODS Severe polytrauma patients admitted from January 2022 to December 2022 in our trauma center were prospectively investigated. Peripheral blood samples were collected at admission (day 1), day 3 and day 7 from them. Included patients were classified based on whether they developed sepsis or not. Clinical outcomes, systematic inflammatory response, lymphocyte subpopulation, CD4 + T cell ferroptosis were collected, detected and analyzed. RESULTS Notable lymphopenia was observed on the first day after severe trauma and failed to normalize on the 7th day if patients were complicated with sepsis, in which CD4 + T cell was the subset of lymphocyte that depleted most pronouncedly. Lymphocyte loss was significantly correlated with the acute and biphasic systemic inflammatory response. Ferroptosis participated in the death of CD4 + T cells, potentially mediated by the downregulation of xCT-GSH-GPX4 pathway. CD4 + T cells ferroptosis had a conducive predicting value for the development of sepsis following severe trauma. CONCLUSIONS CD4 + T cells ferroptosis occurs early in the acute stage of severe polytrauma, which may become a promising biomarker and therapeutic target for post-traumatic sepsis.

Abstract
INTRODUCTION Pneumonia is a common complication after severe trauma that is associated with worse outcomes with increased mortality. Critically ill trauma patients also have persistent inflammation and bone marrow dysfunction that manifests as persistent anemia. Terminal erythropoiesis, which occurs in bone marrow structures called erythroblastic islands (EBIs), has been shown to be impacted by trauma. Using a preclinical model of polytrauma (PT) and pneumonia, we sought to determine the effect of infection on bone marrow dysfunction and terminal erythropoiesis. METHODS Male and female Sprague-Dawley rats aged 9 to 11 weeks were subjected to either PT (lung contusion, hemorrhagic shock, cecectomy, and bifemoral pseudofracture) or PT with postinjury day 1 Pseudomonas pneumonia (PT-PNA) and compared with a naive cohort. Erythroblastic islands were isolated from bone marrow samples and imaged via confocal microscopy. Hemoglobin, early bone marrow erythroid progenitors, erythroid cells/EBI, and % reticulocytes/EBI were measured on day 7. Significance was defined as p < 0.05. RESULTS Day 7 hemoglobin was significantly lower in both PT and PT-PNA groups compared with naive (10.8 ± 0.6 and 10.9 ± 0.7 vs. 12.1 ± 0.7 g/dL [ p < 0.05]). Growth of bone marrow early erythroid progenitors (colony-forming units-granulocyte, erythrocyte, monocyte, megakaryocyte; erythroid burst-forming unit; and erythroid colony-forming unit) on day 7 was significantly reduced in PT-PNA compared with both PT and naive. Despite a peripheral reticulocytosis following PT and PT-PNA, the percentage of reticulocytes/EBI was not different between naive, PT, and PT-PNA. However, the number of erythroblasts/EBI was significantly lower in PT-PNA compared with naive (2.9 ± 1.5 [ p < 0.05] vs. 8.9 ± 1.1 cells/EBI macrophage). In addition to changes in EBI composition, EBIs were also found to have significant structural changes following PT and PT-PNA. CONCLUSION Multicompartmental PT altered late-stage erythropoiesis, and these changes were augmented with the addition of pneumonia. To improve outcomes following trauma and pneumonia, we need to better understand how alterations in EBI structure and function impact persistent bone marrow dysfunction and anemia.

Abstract
ABSTRACT Background: After severe injury, optical measures of microvascular blood flow (MBF) decrease and do not normalize with resuscitation to normal blood pressure. These changes are associated with organ dysfunction, coagulopathy, and death. However, the pathophysiology is not well understood. Several possible pathways could also contribute to the development of trauma-induced coagulopathy (TIC). A small-animal model of trauma-related MBF derangement that persists after resuscitation and includes TIC would facilitate further study. Parametric contrast-enhanced ultrasound (CEUS) is particularly advantageous in this setting, because it noninvasively assesses MBF in large, deep vascular beds. We sought to develop such a model, measuring MBF with CEUS. Methods: Sixteen male Sprague-Dawley rats were anesthetized, ventilated, and cannulated. Rats were subjected to either no injury (sham group) or a standardized polytrauma and pressure-targeted arterial catheter hemorrhage with subsequent whole blood resuscitation (trauma group). At prespecified time points, CEUS measurements of uninjured quadriceps muscle, viscoelastic blood clot strength, and complete blood counts were taken. Results: After resuscitation, blood pressure normalized, but MBF decreased and remained low for the rest of the protocol. This was primarily driven by a decrease in blood volume with a relative sparing of blood velocity. Viscoelastic blood clot strength and platelet count also decreased and remained low throughout the protocol. Conclusion: We present a rat model of MBF derangement in uninjured skeletal muscle and coagulopathy after polytrauma that persists after resuscitation with whole blood to normal macrohemodynamics. Parametric CEUS analysis shows that this change is primarily due to microvascular obstruction. This platform can be used to develop a deeper understanding of this important process.

Abstract
BACKGROUND Andexanet alfa (andexanet) is a reversal agent for use in patients with life-threatening or uncontrolled bleeding treated with oral factor Xa (FXa) inhibitors. There are limited data on the dose-response relationship of andexanet and FXa inhibitor-related bleeding. OBJECTIVE The aim of this study was to assess the dose-related effectiveness of andexanet in reducing blood loss, improving survival, and reversing apixaban anticoagulation in a porcine polytrauma model. METHODS Apixaban was given orally to 40 male pigs for 3 days at a dose of 20 mg/d. On day 3, following bilateral femur fractures and blunt liver injury, animals (n = 8/group) received andexanet (250-mg bolus, 250-mg bolus + 300-mg 2-hour infusion, 500-mg bolus, or 500-mg bolus + 600-mg 2-hour infusion) or vehicle (control). Total blood loss was the primary endpoint. Coagulation parameters were assessed for 300 minutes or until death. Data were analyzed with a mixed-model analysis of variance. RESULTS Administration of 250-mg bolus + 300-mg infusion, andexanet 500-mg bolus, and 500-mg bolus + 600-mg infusion significantly decreased total blood loss by 37, 58, and 61%, respectively (all p < 0.0001), with 100% survival. Andexanet 250-mg bolus was ineffective in reducing total blood loss (6%) and mortality (63% survival) versus controls. Andexanet 500-mg bolus ± infusion neutralized anti-FXa activity to less than 50 ng/mL. Andexanet neutralization of thrombin generation and thromboelastometry parameters was dose and infusion time dependent. CONCLUSION In a porcine polytrauma model with major bleeding on apixaban, andexanet dose dependently decreased anti-FXa activity. Lower anti-FXa levels (<50 ng/mL) with andexanet 500-mg bolus ± infusion were correlated with 60% less blood loss and 100% survival versus controls.

Abstract
BACKGROUND Deep vein thrombosis (DVT) is a common complication in orthopedic patients. Previous studies have focused on major orthopedic surgery.There are few studies with multiple trauma. We aimed to describe the prevalence of DVT and compare the predictive power of the different risk assessment scales in patients with multiple trauma. METHODS This prospective cohort study involved multiple trauma patients admitted to our hospital between October 2021 and December 2022. Data were prospectively collected for thrombotic risk assessments using the Risk Assessment Profile for thromboembolism(RAPT), the DVT risk assessment score (DRAS), and the Trauma Embolic Scoring System (TESS), respectively. The receiver operation characteristic (ROC) curve and the area under the curve (AUC) were evaluated to compare the predictive power. The whole leg duplex ultrasound of both lower extremities Doppler ultrasound was used to determine DVT incidence. RESULTS A total of 210 patients were included, and the incidence of DVT was 26.19%. Distal DVT accounted for 87.27%; postoperative DVT, 72.73%; and bilateral lower extremity thrombosis, 30.91%. There were significant differences in age, education degree, pelvic fracture, surgery, ISS, D-dimer level, length of hospital stay and ICU stay between the thrombosis group and the non-thrombosis group. The AUCs for RAPT, DRAS, and TESS were 0.737, 0.710, and 0.683, respectively. There were no significant differences between the three ROC curves. CONCLUSIONS The incidence of DVT was relatively high during hospitalization. We prospectively validated the tests to predict risk of DVT among patients with multiple trauma to help trauma surgeons in the clinical administration of DVT prophylaxis.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a major complication of trauma. Currently, there are few studies summarising the evidence for prophylaxis in trauma settings. This review provides evidence for the use of VTE prophylactic interventions in trauma patients to produce evidence-based guidelines. METHODS A PRISMA-compliant review was conducted from Sep 2021 to June 2023, using Embase, Medline and Google Scholar. The inclusion criteria were: randomized-controlled trials (RCTs) in English published after 2000 of adult trauma patients comparing VTE prophylaxis interventions, with a sample size higher than 20. The network analysis was conducted using RStudio. The results of the pairwise comparisons were presented in the form of a league table. The quality of evidence and heterogeneity sensitivity were assessed. The primary outcome focused on venous thromboembolism (VTE), and examined deep vein thrombosis (DVT) and pulmonary embolism (PE) as separate entities. The secondary outcomes included assessments of bleeding and mortality. PROSPERO registration: CRD42021266393. RESULTS Of the 7,948 search results, 23 studies with a total of 21,312 participants fulfilled screening criteria, which included orthopaedic, spine, solid organ, brain, spinal cord, and multi-region trauma. Of the eight papers comparing chemical prophylaxis medications in patients with hip or lower limb injuries, fondaparinux and enoxaparin were found to be significantly superior to placebo in respect of prevention of DVT, with no increased risk of bleeding. Regarding mechanical prophylaxis, meta-analysis of two studies of inferior vena cava filters failed to provide significant benefits to major trauma patients. CONCLUSION Enoxaparin and fondaparinux are safe and effective options for VTE prevention in trauma patients, with fondaparinux being a cheaper and easier administration option between the two. Inconclusive results were found in mechanical prophylaxis, requiring more larger-scale RCTs.

Abstract
BACKGROUND There are multiple reported injuries associated with cardiopulmonary resuscitation, most of them caused by the force of compressions, like sternal and rib fractures, abdominal organ injuries like splenic rupture, liver lacerations, and injuries to the upper airway and skin. Injuries related to defibrillation and cardioversion are rare, mostly related to skin and muscle injuries on where the defibrillation paddles were placed. CASE REPORT A 52-year-old man presented to the Emergency Department with crushing chest pain. The patient was suffering from a myocardial infarction, and during percutaneous coronary intervention, had to be defibrillated on the angioplasty table. This resulted in fracture-dislocations on both shoulders. The patient was transferred to our orthopedics clinic and was operated on within 5 days of angioplasty. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Early diagnosis and treatment are important, and can prevent long-term morbidity. However, cardiopulmonary resuscitation and defibrillation are acts that are most commonly performed in the emergency department. Injury prevention by controlling the patient's position, in this case, positions of the shoulders, is an important factor that emergency physicians can control and effect.

Abstract
BACKGROUND Surgical treatment of pelvic and acetabular fractures is an advanced intervention with a high risk of subsequent complications. These patients are often polytrauma patients with multiple injuries in several organ systems. The optimal timing for the definitive surgery of these fractures has been debated. The primary aim of this study was to investigate the influence of timing of definitive surgery on the rate of unplanned reoperations. Secondary aims included its influence on the occurrence of adverse events and mortality. METHODS All patients from 18 years with a surgically treated pelvic or acetabular fracture operated at the Karolinska University Hospital in Sweden during 2010 to 2019 were identified and included. Data was collected through review of medical records and radiographs. Logistic regression analysis was performed to evaluate factors associated with unplanned reoperations and other adverse events. RESULTS A total of 419 patients with definitive surgical treatment within 1 month of a pelvic (n = 191, 46%) or an acetabular (n = 228, 54%) fracture were included. The majority of the patients were males (n = 298, 71%) and the mean (SD, range) age was 53.3 (19, 18-94) years. A total of 194 (46%) patients had their surgery within 72 h (early surgery group), and 225 (54%) later than 72 h (late surgery group) after the injury. 95 patients (23%) had an unplanned reoperation. There was no difference in the reoperation rate between early (n = 44, 23%) and late (n = 51, 23%) surgery group (p = 1.0). A total of 148 patients (35%) had any kind of adverse event not requiring reoperation. The rate was 32% (n = 62) in the early, and 38% (n = 86) in the late surgery group (p = 0.2). When adjusting for relevant factors in regression analyses, no associations were found that increased the risk for reoperation or other adverse events. The 30-day mortality was 2.1% (n = 4) for the early and 2.2% (n = 5) for the late surgery group (p = 1.0). The 1-year mortality was 4.1% (n = 8) for the early and 7.6% (n = 17) for the late surgery group (p = 0.2). CONCLUSIONS Early (within 72 h) definitive surgery of patients with pelvic or acetabular fractures seems safe with regard to risk for reoperation, other adverse events and mortality.

Abstract
BACKGROUND Our objective was to optimize a novel damage control resuscitation (DCR) cocktail composed of hydroxyethyl starch, vasopressin, and fibrinogen concentrate for the polytraumatized casualty. We hypothesized that slow intravenous infusion of the DCR cocktail in a pig polytrauma model would decrease internal hemorrhage and improve survival compared with bolus administration. METHODS We induced polytrauma, including traumatic brain injury (TBI), femoral fracture, hemorrhagic shock, and free bleeding from aortic tear injury, in 18 farm pigs. The DCR cocktail consisted of 6% hydroxyethyl starch in Ringer's lactate solution (14mL/kg), vasopressin (0.8U/kg), and fibrinogen concentrate (100mg/kg) in a total fluid volume of 20mL/kg that was either divided in half and given as two boluses separated by 30 minutes as control or given as a continuous slow infusion over 60 minutes. Nine animals were studied per group and monitored for up to 3 hours. Outcomes included internal blood loss, survival, hemodynamics, lactate concentration, and organ blood flow obtained by colored microsphere injection. RESULTS Mean internal blood loss was significantly decreased by 11.1mL/kg with infusion compared with the bolus group (p = .038). Survival to 3 hours was 80% with infusion and 40% with bolus, which was not statistically different (Kaplan Meier log-rank test, p = .17). Overall blood pressure was increased (p < .001), and blood lactate concentration was decreased (p < .001) with infusion compared with bolus. There were no differences in organ blood flow (p > .09). CONCLUSION Controlled infusion of a novel DCR cocktail decreased hemorrhage and improved resuscitation in this polytrauma model compared with bolus. The rate of infusion of intravenous fluids should be considered as an important aspect of DCR.

Abstract
BACKGROUND Manubriosternal dislocations are a rare entity and frequently associated with thoracic spine fractures and, in minority of cases, with cervical or thoracolumbar fractures. METHODS Our case represents a 38-year-old male who fell from a height resulting in multiple fractures, amongst others of the first lumbar vertebra. At primary survey and computed tomography scan no manubriosternal injury was apparent. After posterior stabilization of the thoracolumbar vertebrae a manubriosternal dislocation was identified and stabilized using plate-and-screw fixation. RESULTS Clinical findings of a manubriosternal dislocation are not always obvious, allowing them to be missed at initial assessment. CONCLUSIONS Manubriosternal dislocations can be missed at the initial investigation, even on cross-sectional imaging, and only become visible after spine stabilization because of the tight relationship between sternum and vertebrae in the thoracic cage. There is no unanimity in literature for surgical treatment of manubriosternal dislocations, although plate fixation is generally considered a safe and effective treatment option.

Abstract
OBJECTIVE This study aimed to explore potential risk factors for the occurrence of multiple organ dysfunction syndrome (MODS) in patients with multiple injuries by evaluating neutrophil-to-lymphocyte ratio (NLR)-associated trauma severity. METHODS This retrospective case-control study included 95 patients with multiple injuries, who were admitted to our hospital (between January 2018 and December 2020). Clinical data including gender, age, underlying disease, number of injury sites (NIS), injury severity score (ISS), hemoglobin level within 24 h of admission (HL-24h), neutrophil count (NC), white blood cell count, platelet count (PC), NLR, d-dimer level, activated partial thromboplastin time (APTT), complicated shock within 24 h of admission (CS-24h), length of stay, as well as prognostic outcome was systematically analyzed. According to MODS occurrence, patients were divided into a MODS group (n = 27) and a non-MODS group (n = 68). The risk factors affecting patients with multiple injuries complicated by MODS were identified using univariate and multivariate logistic regression analyses. Candidate risk factors were further analyzed using receiver operating characteristic (ROC) curves. RESULTS Univariate analysis revealed a significant difference between the MODS and non-MODA groups in terms of NIS, ISS, HL-24h, PC, APTT, d-dimer level, CS-24h, NLR, NC, prognostic outcome, and other indicators (p < .05). Multivariate logistic regression analysis showed that d-dimer levels within 24 h of admission and ISS, NLR, and CS-24h were significantly associated with multiple injuries complicated by MODS. Compared with the non-MODS controls, the NLR in the MODS group showed a much higher level and tended to rise with the increase in ISS score, indicating a significant intergroup difference (p < .05). The ROC curve analysis results suggested that the NLR had good sensitivity and specificity for predicting the prognosis of patients with MODS with multiple injuries. CONCLUSION d-dimer level, ISS, NLR, and CS-24h are important risk factors for MODS in patients with multiple injuries. Notably, NLR expression may be a good indicator of injury severity and predictor of the occurrence of MODS in patients with multiple injuries. Therefore, assessment of injury severity and coagulation function, active resuscitation, as well as prevention of infection should be emphasized during treatment of multiple injuries, to reduce and prevent the risk of MODS in patients with multiple injuries.

Abstract
ABSTRACT Background: Pneumonia is a frequent complication after polytrauma. This study aims to evaluate the ability of different serum markers to identify patients at risk of developing pneumonia after polytrauma. Methods: A retrospective analysis of prospectively collected data in polytraumatized patients with concomitant thoracic trauma (Injury Severity Score ≥16, Abbreviated Injury Scale Thorax ≥ 3) was performed. The study cohort was divided into patients with and without pneumonia during the clinical course. Serum levels of lung epithelial (CYFRA 21-1), endothelial (Ang-2), and inflammatory (PTX-3, sRAGE, IL-6, IL-10) markers were measured upon arrival in the trauma room and on days 2 and 5. Results: A total of 73 patients and 16 healthy controls were included in this study. Of these, 20 patients (27.4%) developed pneumonia. Polytraumatized patients showed significantly increased CYFRA 21-1 levels with a distinct peak after admission compared with healthy controls. Serum PTX-3 significantly increased on day 2 in polytraumatized patients compared with healthy controls. Injury Severity Score and demographic parameters were comparable between both groups (pneumonia vs. no pneumonia). No statistically significant difference could be observed for serum levels of CYFRA 21-1, Ang-2, PTX-3, sRAGE, IL-6, and IL-10 between the groups (pneumonia vs. no pneumonia) on all days. Logistic regression revealed a combination of IL-6, IL-10, sRAGE, and PTX-3 to be eventually helpful to identify patients at risk of developing pneumonia and our newly developed score was significantly higher on day 0 in patients developing pneumonia ( P < 0.05). Conclusion: The investigated serum markers alone are not helpful to identify polytraumatized patients at risk of developing pneumonia, while a combination of IL-6, IL-10, PTX-3, and sRAGE might be.

Abstract
INTRODUCTION Traumatic brain injury (TBI) can trigger vision-based sequelae such as oculomotor and accommodative abnormalities, visual-vestibular integrative dysfunction, visual field loss, and photosensitivity. The need for diagnosis and management of TBI-related vision impairment has increased because of the increasing frequencies of combat warfighters returning from Iraq and Afghanistan with TBIs. The purpose of this research was to learn the sequelae of rehabilitation service delivery to veterans with TBI-related visual dysfunction after they are diagnosed. To accomplish this, we investigated vision rehabilitation assessments and interventions provided to veterans with TBI-related visual dysfunction at the Department of Veterans Affairs (VA) specialty polytrauma facilities for the 2 years following their injury. The research questions asked what assessments, interventions, and prescribed assistive devices were provided by VA specialty clinics (e.g., occupational therapy, polytrauma, and blind rehabilitation) and how service delivery was affected by demographic and clinical variables. MATERIALS AND METHODS A retrospective design was used to analyze VA data using natural language processing of unstructured clinician notes and logistic regression of structured data. Participants included 350 veterans with TBI who received rehabilitation at one of the five VA Polytrauma Rehabilitation Centers (Tampa, FL; Richmond, VA; Minneapolis, MN; San Antonio, TX; and Palo Alto, CA) between 2008 and 2017 and who were administered the 2008 congressionally mandated "Traumatic Brain Injury Specific Ocular Health and Visual Functioning Exam." The outcome variables were vision assessments, interventions, and prescribed assistive technology discovered via natural language processing of clinician notes as well as the vision rehabilitation specialty clinics providing the clinical care (polytrauma, occupational therapy, outpatient blind rehabilitation, inpatient blind rehabilitation, optometry, and low vision) extracted from VA structured administrative data. RESULTS Veterans receiving rehabilitation for TBI-related vision dysfunction were most frequently assessed for saccades, accommodation, visual field, and convergence. Intervention was provided most frequently for eye-hand coordination, saccades, accommodation, vergence, and binocular dysfunction. Technology provided included eyeglasses, wheelchair/scooter, walker/cane, aids for the blind, and computer. There was an overlap in the services provided by specialty clinics. Services available and delivered were significantly associated with the comorbidities of each patient and the specialty clinics available at each VA Polytrauma Rehabilitation Center. CONCLUSIONS The delivery of patient services should be driven by the needs of veterans and not by system-level factors such as the availability of specific vision rehabilitation services at specific locations. Traditional low vision and blind rehabilitation programs were not designed to treat the comorbidities and symptoms associated with TBI. To address this challenge, blind rehabilitation and neurologic recovery cross training is needed. Our findings document how five VA Polytrauma Rehabilitation Centers implemented this training in 2008. The next step is to extend and standardize this new paradigm to community care, where these post-deployment patients now reside.

Abstract
INTRODUCTION Blast injury is a unique condition that carries a high rate of morbidity and mortality, often with mixed penetrating and blunt injuries. OBJECTIVE This review highlights the pearls and pitfalls of blast injuries, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION Explosions may impact multiple organ systems through several mechanisms. Patients with suspected blast injury and multisystem trauma require a systematic evaluation and resuscitation, as well as investigation for injuries specific to blast injuries. Blast injuries most commonly affect air-filled organs but can also result in severe cardiac and brain injury. Understanding blast injury patterns and presentations is essential to avoid misdiagnosis and balance treatment of competing interests of patients with polytrauma. Management of blast victims can also be further complicated by burns, crush injury, resource limitation, and wound infection. Given the significant morbidity and mortality associated with blast injury, identification of various injury patterns and appropriate management are essential. CONCLUSIONS An understanding of blast injuries can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Abstract
BACKGROUND Rapid triage of blunt agonal trauma patients is necessary to maximize survival, but autopsy is uncommon, slow, and rarely informs resuscitation guidelines. Postmortem computed tomography (PMCT) can serve as an adjunct to autopsy in guiding blunt agonal trauma resuscitation. METHODS Retrospective cohort review of trauma decedents who died at or within 1 hour of arrival following blunt trauma and underwent noncontrasted PMCT. Primary outcome was the prevalence of mortal injury defined as potential exsanguination (e.g., cavitary injury, long bone and pelvic fractures), traumatic brain injury, and cervical spine injury. Secondary outcomes were potentially mortal injuries (e.g., pneumothorax) and misplacement airway devices. Patients were grouped by whether arrest occurred prehospital/in-hospital. Univariate analysis was used to identify differences in injury patterns including multiple-trauma injury patterns. RESULTS Over a 9-year period, 80 decedents were included. Average age was 48.9 ± 21.7 years, 68% male, and an average ISS of 42.3 ± 16.3. The most common mechanism was motor vehicle accidents (67.5%) followed by pedestrian struck (15%). Of all decedents, 62 (77.5%) had traumatic arrest prehospital while 18 (22.5%) arrived with pulse. Between groups there were no significant differences in demographics including ISS. The most common mortal injuries were traumatic brain injury (40%), long bone fractures (25%), moderate/large hemoperitoneum (22.5%), and cervical spine injury (25%). Secondary outcomes included moderate/large pneumothorax (18.8%) and esophageal intubation rate of 5%. There were no significant differences in mortal or potentially mortal injuries, and no differences in multiple-trauma injury patterns. CONCLUSION Fatal blunt injury patterns do not vary between prehospital and in-hospital arrest decedents. High rates of pneumothorax and endotracheal tube misplacement should prompt mandatory chest decompression and confirmation of tube placement in all blunt arrest patients. LEVEL OF EVIDENCE Prognostic and Epidemiological; Level IV.

Abstract
ABSTRACT Several studies have demonstrated the clinical utility of tranexamic acid (TXA) for use in trauma patients presenting with significant hemorrhage. Tranexamic acid is an antifibrinolytic that inhibits plasminogen activation, and plasmin activity has been shown to mitigate blood loss and reduce all-cause mortality in the absence of adverse vascular occlusive events. Recent clinical developments indicate TXA is safe to use in patients with concomitant traumatic brain injury (TBI); however, the prehospital effects are not well understood. Importantly, TXA has been associated with seizure activity. Therefore, this study sought to evaluate the effects of early administration of TXA on neurological recovery and electroencephalogram (EEG) abnormalities following penetrating TBI with concomitant hypoxemia and hemorrhagic shock. We hypothesized that early administration of TXA will provide hemodynamic stabilization and reduce intracerebral hemorrhage, which will result in improved neurological function. To test this hypothesis, Sprague-Dawley rats received a unilateral, frontal penetrating ballistic-like brain injury by inserting a probe into the frontal cortex of the anesthetized rat. Five minutes following brain injury, animals underwent 30 min of respiratory distress and 30 min of hemorrhage. Upon completion of the hemorrhage phase, animals received the initial dose of drug intravenously over 10 min after which the prehospital phase was initiated. During the prehospital phase, animals received autologous shed whole blood as needed to maintain a MAP of 65 mm Hg. After 90 min, "in-hospital" resuscitation was performed by administering the remaining shed whole blood providing 100% oxygen for 15 min. Upon recovery from surgery, animals were administered their second dose of vehicle or TXA intravenously over 8 h. Tranexamic acid induced an early improvement in neurologic deficit, which was statistically significant compared with vehicle at 24, 48, and 72 h at three doses tested. Analysis of cerebral hemoglobin content and intracerebral lesion progression revealed 100 mg/kg provided the optimal effects for improvement of neuropathology and was continued for determination of adverse treatment effects. We observed no exacerbation of cerebral thrombosis, but TXA treatment caused an increased risk of EEG abnormalities. These results suggest that TXA following polytrauma with concomitant brain injury may provide mild neuroprotective effects by preventing lesion progression, but this may be associated with an increased risk of abnormal EEG patterns. This risk may be associated with TXA inhibition of glycine receptors and may warrant additional considerations during the use of TXA in patients with severe TBI.

Abstract
Traumatic brain injury (TBI) survivors often experience debilitating consequences. Due to the high impact nature of TBI, patients often experience concomitant peripheral injuries (ie, polytrauma). A common, yet often overlooked, comorbidity of TBI is chronic pain. Therefore, this study investigated how common concomitant peripheral injuries (ie, femoral fracture and muscle crush) can affect long-term behavioral and structural TBI outcomes with a particular focus on nociception. Rats were randomly assigned to 1 of 4 groups: polytrauma (POLY; ie, fracture + muscle crush + TBI), peripheral injury (PERI; ie, fracture + muscle crush + sham TBI), TBI (ie, sham fracture + sham muscle crush + TBI), and sham-injured (SHAM; ie, sham fracture + sham muscle crush + sham TBI). Rats underwent behavioral testing at 3-, 6-, and 11-weeks postinjury, and were then euthanized for postmortem magnetic resonance imaging (MRI). POLY rats had a persisting increase in pain sensitivity compared to all groups on the von Frey test. MRI revealed that POLY rats also had abnormalities in the cortical and subcortical brain structures involved in nociceptive processing. These findings have important implications and provide a foundation for future studies to determine the underlying mechanisms and potential treatment strategies for chronic pain in TBI survivors. PERSPECTIVE: Rats with TBI and concomitant peripheral trauma displayed chronic nociceptive pain and MRI images also revealed damaged brain structures/pathways that are involved in chronic pain development. This study highlights the importance of polytrauma and the affected brain regions for developing chronic pain.

Abstract
BACKGROUND Trauma patients are at high risk of Venous thromboembolism (VTE), but compared to well-established deep venous thrombosis (DVT), data specifically evaluating post-traumatic pulmonary embolism (PE) are scarce. The aim of this study is to assess whether PE represents a distinct clinical entity with injury pattern, risk factors, and prophylaxis strategy different from DVT, among severe poly-trauma patients. PATIENTS AND METHODS We retrospectively enrolled patients admitted to our level I trauma center from January 2011 to December 2021 who were diagnosed with severe multiple traumatic injuries and identified thromboembolic events among them. We regarded four groups as None (without thromboembolic events), DVT only, PE only, and PE with DVT. Demographics, injury characteristics, clinical outcomes, and treatments were collected and analyzed in individual groups. Patients were also classified according to the occurring time of PE, and indicative symptoms and radiological findings were compared between early PE (≤ 3 days) and late PE (> 3 days). Logistic regression analyses were conducted to explore independent risk factors for different VTE patterns. RESULTS Among 3498 selected severe multiple traumatic patients, there were 398 episodes of DVT only, 19 of PE only, and 63 of PE with DVT. Injury variables associated with PE only included shock on admission and severe chest trauma. Severe pelvic fracture and mechanical ventilator days (MVD) ≥ 3 were the independent risk factors for PE with DVT. There were no significant differences in the indicative symptoms and location of pulmonary thrombi between the early and late PE groups. Obesity and severe lower extremity injury might have an impact on the incidence of early PE, while patients with a severe head injury and higher ISS are particularly at risk for developing late PE. CONCLUSION Occurring early, lacking association with DVT, and possessing distinct risk factors warrant PE in severe poly-trauma patients special attention, especially for its prophylaxis strategy.

Abstract
ABSTRACT Background : Overall outcomes for trauma patients have improved over time. However, mortality for postinjury sepsis is unchanged. The use of relevant preclinical studies remains necessary to understand mechanistic changes after injury and sepsis at the cellular and molecular level. We hypothesized that a preclinical rodent model of multicompartmental injury with postinjury pneumonia and chronic stress would replicate inflammation and organ injury similar to trauma patients in the intensive care unit. Methods : Male and proestrus female Sprague-Dawley rats ( n = 16/group) were subjected to either polytrauma (PT) (lung contusion, hemorrhagic shock, cecectomy, and bifemoral pseudofracture), PT with daily chronic restraint stress (PT/CS), PT with postinjury day one Pseudomonas pneumonia (PT + PNA), PT/CS with pneumonia (PT/CS + PNA) or naive controls. Weight, white blood cell count, plasma toll-like receptor 4 (TLR4), urine norepinephrine (NE), hemoglobin, serum creatinine, and bilateral lung histology were evaluated. Results : PT + PNA and PT/CS + PNA groups lost more weight compared with those without sepsis (PT, PT/CS) and naive rats ( P < 0.03). Similarly, both PT + PNA and PT/CS + PNA had increased leukocytosis and plasma TLR4 compared with uninfected counterparts. Urine NE was elevated in PT + PNA and PT/CS + PNA compared with naive ( P < 0.03), with PT/CS + PNA exhibiting the highest levels. PT/CS + PNA exhibited worse acute kidney injury with elevated serum creatinine compared with PT/CS ( P = 0.008). PT/CS + PNA right and left lung injury scores were worse than PT + PNA ( P < 0.01). Conclusions : Sepsis, with postinjury pneumonia, induced significant systemic inflammation, organ dysfunction following polytrauma and chronic stress. Advanced animal models that replicate the critically ill human condition will help overcome the classic limitations of previous experimental models and enhance their translational value.

Abstract
This review summarises the principles for diagnosing and treating acute urological trauma. Renal trauma can be life threatening, although most injuries are self-limiting. Development in imaging and non-operative measures allows for a more conservative and nephron-sparing approach. Pelvic fracture urethral injury is often associated with multiple injuries. Strategy for intervention depends on whether the injury is partial or complete, anterior or posterior. Penile fracture is a rare but acute urological condition. Surgical treatment is necessary to minimize risk of complications. If handled accordingly, the functional outcome is good.

Abstract
ABSTRACT Background: Traumatic brain injury (TBI) is a significant cause of morbidity and mortality in the United States, with an annual cost of 60 billion dollars. There is evidence suggesting that in the post-TBI period, the gastrointestinal tract plays a central role in driving organ and immune dysfunction and may be the source of increased circulating proinflammatory mediators. In this study, we examined systemic inflammation and bacterial dysbiosis in patients who sustained a TBI with or without polytrauma. Using a mouse model of TBI, we further show how neuroinflammation after TBI is potentially linked to disruptions in gut homeostasis such as intestinal transit and inflammation. Methods: During a study of trauma patients performed from September 1, 2018, to September 1, 2019, at a single, level 1 trauma center, TBI patients aged 21 to 95 years were enrolled. Patients were categorized as TBI based on evidence of acute abnormal findings on head computed tomographic scan, which was a combination of isolated TBI and TBI with polytrauma. Blood and stool samples were collected between 24 h and 3 days after admission. Twelve plasma samples and 10 fecal samples were used for this study. Healthy control samples were obtained from a healthy control biobank. We examined systemic inflammation and bacterial changes in patients who sustained a TBI. In addition, TBI was induced in 9- to 10-week-old male mice; we assessed neuroinflammation, and intestine transit (motility) and bacterial changes 24 h after TBI. Results: When compared with healthy controls, TBI patients had increased systemic inflammation as evidenced by increased levels of IFN-γ and MCP-1 and a trend toward an increase of IL-6 and IL-8 ( P = 0.0551 and P = 0.0549), respectively. The anti-inflammatory cytokine, IL-4, was also decreased in TBI patients. Although there was a trend of an increase in copy number of Enterobacteriaceae and a decrease in copy number of Lactobacillus in both patients and mice after TBI, these trends were not found to be significantly different. However, TBI significantly increased the copy number of another potential pathogenic bacteria Bilophila wadsworthia in TBI patients compared with healthy controls. After a moderate TBI, mice had increased expression of TNF-α, IL-6 and IL-1β, CXCL1, s100a9, and Ly6G and decreased IL-10 in the brain lesion after TBI. This accompanied decreased transit and increased TNF-α in the small intestine of mice after TBI. Conclusions: Our findings suggest that TBI increases systemic inflammation, intestinal dysfunction, and neuroinflammation. More studies are needed to confirm whether changes in intestinal motility play a role in post-TBI neuroinflammation and cognitive deficit.

Abstract
INTRODUCTION Traumatic spinal injuries are frequent and their management is debated, especially in major trauma patients. This study aims to describe a large population of major trauma patients with vertebral fractures to improve prevention measures and fracture management. PATIENTS AND METHODS Retrospective analysis of 6274 trauma patients prospectively collected between October 2010 and October 2020. Collected data include demographics, mechanism of trauma, type of imaging, fracture morphology, associated injuries, injury severity score (ISS), survival, and death timing. The statistical analysis focused on mechanism of trauma and the search of predictive factors for critical fractures. RESULTS Patients showed a mean age of 47 years and 72.5% were males. Trauma included 59.9% of road accidents and 35.1% of falls. 30.7% patients had at least a severe fracture, while 17.2% had fractures in multiple spinal regions. 13.7% fractures were complicated by spinal cord injury (SCI). The mean ISS of the total population was 26.4 (SD 16.3), with 70.7% patients having an ISS≥16. There is a higher rate of severe fractures in fall cases (40.1%) compared to RA (21.9% to 26.3%). The probability of a severe fracture increased by 164% in the case of fall and by 77% in presence of AIS≥3 associated injury of head/neck while reduced by 34% in presence of extremities associated injuries. Multiple level injuries increased with ISS rise and in the case of extremities associated injuries. The probability of a severe upper cervical fracture increased by 5.95 times in the presence of facial associated injuries. The mean length of stay was 24.7 days and 9.6% of patients died. CONCLUSIONS In Italy, road accidents are still the most frequent trauma mechanism and cause more cervico-thoracic fractures, while falls cause more lumbar fractures. Spinal cord injuries represent an indicator of more severe trauma. In motorcyclists or fallers/jumpers, there is a higher risk of severe fractures. When a spinal injury is diagnosed, the probability of a second vertebral fracture is consistent. These data could help the decisional workflow in the management of major trauma patients with vertebral injury.

Abstract
BackgroundTrauma is still a leading cause of morbidity and mortality, especially in the younger population. Trauma patients need a precise, early diagnostic to avoid complications like multiorgan failure and sepsis. Exosomes were described as markers and mediators in trauma. The aim of the present study was to analyze, whether the surface epitopes of plasma-exosomes can reflect the injury pattern in polytrauma.Material and MethodsPolytraumatized patients (Injury Severity Score = ISS ≥16, n = 38) were subdivided according to the predominant injury in either abdominal trauma, chest trauma or traumatic brain injury (TBI). Plasma exosomes were isolated via size exclusion chromatography. The concentration and size distribution of the plasma exosomes from emergency room samples were measured by nanoparticle tracking analysis. The exosomal surface antigens were investigated by bead-based multiplex flow cytometry and compared with healthy controls (n=10).ResultsIn contrast to other studies, we did not observe an increase in the total amount of plasma exosomes in polytrauma patients (1,15x109 vs. 1,13x109 particles/ml), but found changes in the exosomal surface epitopes. We found a significant reduction of CD42a+ (platelet-derived) exosomes in polytrauma patients, CD209+ (dendritic cell-derived) exosomes in the patients with predominant abdominal trauma, and CD11+ (monocyte-derived) exosomes in the patients with chest trauma. The group of patients with TBI was characterized in contrast by an increase of CD62p+ (endothelial/platelet-derived) exosomes (*p<0.05).ConclusionOur data showed that the polytrauma injury pattern might be reflected by the cellular origin/surface epitopes of plasma-released exosomes immediately after trauma. The observed reduction of CD42+ exosomes in polytrauma patients was not associated with a reduction of total platelets in polytrauma patients.

Abstract
Spondyloptosis in the clinic is rarely reported. We herein present a 47-year-old female, who suffered from a crush injury directly by a heavy cylindrical object from the lateral side. She was diagnosed to have traumatic L3 spondyloptosis with multiple traumas. Staged surgical procedures were conducted and a three-year follow-up was obtained. Eventually, normal spinal alignment was restored, and neurological deficits were gradually improved. At three years follow-up, the motor strength scores and function of the sphincters were incompletely improved. Previously published reports on traumatic lumbar spondyloptosis were reviewed and several critical points for management of this severe type of spinal injury were proposed. First, thoracolumbar and lumbosacral junction were mostly predilection sites. Second, numerous patients involving traumatic lumbar spondyloptosis were achieved to American Spinal Injury Association grade A. Third, lumbar spondyloptosis was commonly coupling with cauda equina injury. Finally, the outcomes were still with poorly prognosis and recovery of patients was correlation to spondyloptosis severity. Based on this case report and literatures review, we highlighted that the spinal alignment restoration relying on staged operations and following rehabilitation hereof are both important once facing with multiple traumas. Furthermore, we suggested to perform routine CT angiography during lumbar spondyloptosis to justify whether there are large vessel compression or injury.

Abstract
BACKGROUND Patients suffering from severe trauma experience substantial immunological stress. Lung injury is a known risk factor for the development of posttraumatic complications, but information on the long-term course of the pulmonary inflammatory response and treatment with mild hypothermia are scarce. AIM To investigate the pulmonary inflammatory response to multiple trauma and hemorrhagic shock in a porcine model of combined trauma and to assess the immunomodulatory properties of mild hypothermia. METHODS Following induction of trauma (blunt chest trauma, liver laceration, tibia fracture), two degrees of hemorrhagic shock (45 and 50%) over 90 (n = 30) and 120 min. (n = 20) were induced. Animals were randomized to hypothermia (33°C) or normothermia (38°C). We evaluated bronchoalveolar lavage (BAL) fluid and tissue levels of cytokines and investigated changes in microRNA- and gene-expression as well as tissue apoptosis. RESULTS We observed a significant induction of Interleukin (IL) 1β, IL-6, IL-8, and Cyclooxygenase-2 mRNA in lung tissue. Likewise, an increased IL-6 protein concentration could be detected in BAL-fluid, with a slight decrease of IL-6 protein in animals treated with hypothermia. Lower IL-10 protein levels in normothermia and higher IL-10 protein concentrations in hypothermia accompanied this trend. Tissue apoptosis increased after trauma. However, intervention with hypothermia did not result in a meaningful reduction of pro-inflammatory biomarkers or tissue apoptosis. CONCLUSION We observed signs of a time-dependent pulmonary inflammation and apoptosis at the site of severe trauma, and to a lower extent in the trauma-distant lung. Intervention with mild hypothermia had no considerable effect during 48 hours following trauma.

Abstract
BACKGROUND The aim is to investigate the predictive values of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1), procalcitonin (PCT) and C-reactive protein (CRP) for multiple trauma-induced acute respiratory distress syndrome (ARDS) complicated with pulmonary infection. METHODS One hundred and twelve patients with multiple trauma-induced ARDS admitted from April 2019 to April 2021 were selected and divided into infection group (n = 49) and non-infection group (n = 63). Their general data and laboratory test indicators were compared. Multivariate logistic regression analysis was utilized to identify the influencing factors for concurrent pulmonary infection. Pearson's analysis was employed to analyze the correlations of sTREM-1, PCT, and CRP with other influencing factors. The predictive values of sTREM-1, PCT, and CRP for pulmonary infection in ARDS patients were evaluated using receiver operating characteristic (ROC) curves. Based on the cutoff values, the patients were assigned to low-, medium-, and high-risk groups. Survival curves were plotted by Kaplan-Meier method to compare the 28-day survival. RESULTS The infection group had significantly higher injury severity score (ISS), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, sTREM-1, PCT, CRP, and macrophage inflammatory protein (MIP)-1α, longer tracheal intubation time and intensive care unit (ICU) stay time, and lower oxygenation index than those of the non-infection group (p < 0.05). Multivariate logistic regression analysis revealed that increased ISS, APACHE II score, as well as elevated blood concentrations of sTREM-1, PCT, CRP and MIP-1α were risk factors for concurrent pulmonary infection (p < 0.05). sTREM-1, PCT, and CRP were positively correlated with ISS, APACHE II score, and MIP-1α (p < 0.05). The areas under ROC curves of sTREM-1, PCT, CRP, and their combination were 0.795, 0.784, 0.756, and 0.860, respectively (p < 0.001), indicating high predictive values. The survival rate of the high-risk group (46.43%) was significantly lower than those of the low-risk group (89.58%) and medium-risk group (75.00%) (p < 0.05). CONCLUSIONS sTREM-1, PCT, and CRP are highly expressed in serum of patients with multiple trauma-induced ARDS complicated with pulmonary infection. The combined detection of three markers is of high predictive value.

Abstract
Background and Objectives: Although urogenital injuries are common in severely injured patients, their diagnosis is often delayed. Predicting genitourinary injuries (GUI), especially in the immediate stages post injury, remains a challenge. This study aims to evaluate and determine positive predictive factors for the presence of GUI in polytrauma patients. Subsequently, these factors shall be used to develop an easy-to-use scoring system, deployable directly in the emergency setting. Materials and Methods: This study evaluates all severely injured patients with an Injury Severity Score (ISS) ≥ 16 admitted to the emergency departments of two German university hospitals between 2016 and 2020. These patients were retrospectively scanned for injuries of the thoracic and/or lumbar spine and/or the pelvic girdle. Demographic data was analyzed alongside trauma mechanism, type of injuries, mortality, length of hospital stays, surgeries, laboratory results, and urological treatment. Subgroup analysis was performed to compare patients with and without GUIs using t-tests. Conducting a binary logistic regression model, the significant factors were combined to create a scoring system, which was further analyzed for accuracy. Results: In total, 413 patients with an average ISS of 33.8 ± 15.0 were identified, and 47 patients (11.4%) sustained urogenital injuries with an average Abbreviated Injury Scale (AIS) score of 2.3 ± 1.1 (range: 1−5). The severity of the pelvic girdle injury correlated with the presence of urogenital injuries (p = 0.002), while there was no correlation with spinal injuries. Moreover, most GUIs resulted from motorcycle accidents (p < 0.001) and 87.2% of these patients were male. Patients with GUI were significantly more likely to show macrohematuria (p < 0.001) on admission and were more severely injured overall (ISS > 34). There was no significant difference in the length of intensive care unit (ICU) stay, the days until discharge, or death rates. Conclusions: Factors or circumstances which reliably predict the presence of GUI were found to include the male sex, a motorcycle accident, high severity of pelvic girdle fractures, macrohematuria on admission to the emergency department, and an ISS > 34. With these findings, we introduce the ‘Urotrauma in Polytrauma patients with Pelvic and/or Spinal injuries’ (UPPS) score for easier prediction of GUI in the emergency setting.

Abstract
Complementopathy, endotheliopathy, and coagulopathy following a traumatic injury are key pathophysiological mechanisms potentially associated with multiple-organ failure (MOF) and mortality. However, the heterogeneity in the responses of complementopathy, endotheliopathy, and coagulopathy to trauma, the nature and extent of their interplay, and their relationship to clinical outcomes remain unclear. Fifty-four poly-trauma patients were enrolled and divided into three subgroups based on their ISS. Biomarkers in blood plasma reflecting complement activation, endothelial damage, and coagulopathy were measured starting from admission to the emergency department and at 3, 6, 12, 24, and 120 hours after admission. Comparative analyses showed that severely injured patients (ISS>24) were associated with longer days on mechanical ventilation, in the intensive care unit and hospital stays, and a higher incidence of hyperglycemia, bacteremia, respiratory failure and pneumonia compared to mildly (ISS<16) or moderately (ISS=16-24) injured patients. In this trauma cohort, complement was activated early, primarily through the alternative complement pathway. As measured in blood plasma, severely injured patients had significantly higher levels of complement activation products (C3a, C5a, C5b-9, and Bb), endothelial damage markers (syndecan-1, sTM, sVEGFr1, and hcDNA), and fibrinolytic markers (D-dimer and LY30) compared to less severely injured patients. Severely injured patients also had significantly lower thrombin generation (ETP and peak) and lower levels of coagulation factors (I, V, VIII, IX, protein C) than less severely injured patients. Complement activation correlated with endothelial damage and hypocoagulopathy. Logistic regression analyses revealed that Bb >1.57 μg/ml, syndecan-1 >66.6 ng/ml or D-dimer >6 mg/L at admission were associated with a higher risk of MOF/mortality. After adjusting for ISS, each increase of the triadic score defined above (Bb>1.57 µg/ml/Syndecan-1>66.6 ng/ml/D-dimer>6.0mg/L) was associated with a 6-fold higher in the odds ratio of MOF/death [OR: 6.83 (1.04-44.96, P=0.046], and a 4-fold greater in the odds of infectious complications [OR: 4.12 (1.04-16.36), P=0.044]. These findings provide preliminary evidence of two human injury response endotypes (traumatized triad and non-traumatized triad) that align with clinical trajectory, suggesting a potential endotype defined by a high triadic score. Patients with this endotype may be considered for timely intervention to create a pro-survival/organ-protective phenotype and improve clinical outcomes.

Abstract
INTRODUCTION The elderly is at risk for traumatic brain injury (TBI), but local data on their morbidity and mortality outcomes was lacking. This study aims to assess the outcome in mortality and functional outcome, Glasgow Outcome Scale (GOS) and factors associated with poor outcomes in patients with TBI more than 60 years old. MATERIALS AND METHODS This single centre retrospective cohort study was carried out involving patients age 60 years old and above with TBI between June 2018 to May 2021. The mortality and GOS at hospital discharge, 30th day, and 90th day of trauma were analysed. The simple logistic regression (SLR) and multiple logistic regression (MLR) were performed to determine factors associated with poor outcomes and mortality. RESULTS A total of 248 patients were analysed. The mean age was 67.5 ± 6.31 years. 156 (62.9%), 26 (10.5%), and 66 (26.6%) had mild, moderate, and severe TBI, respectively. The overall mortality rate was 9.7% and the median(IQR) GOS score were 4(2); p<0.001 at hospital discharge, 30th day and 90th day. There was significant difference in GOS outcomes after 90 days χ2(2) = 136.76 p<0.001. Upon MLR, there was a significant association of polytrauma, Adj. OR 11.04 (2.503-48.711); p < 0.002 and TBI severity: moderate TBI, Adj. OR 71.44(13.028-391.782); p < 0.001 and severe TBI, Adj OR 2533.51 (213.050-30127.644); p<0.001 towards poor outcome. However, only severity of TBI: moderate TBI, Adj. OR 19.48 (1.899-199.094); p=0.012 and severe TBI, Adj OR 26.42 (2.864-243.722); p=0.004 is associated with mortality. CONCLUSION Polytrauma and moderate-severe head injury are associated with poor outcomes and moderate-severe head injury is associated with high mortality.

Abstract
Dysfunctional complement activation and Toll-like receptor signaling immediately after trauma are associated with development of trauma-induced coagulopathy and multiple organ dysfunction syndrome. We assessed the efficacy of the combined inhibition therapy of complement factor C5 and the TLR co-receptor CD14 on thrombo-inflammation and organ damage in an exploratory 72-h polytrauma porcine model, conducted under standard surgical and intensive care management procedures. Twelve male pigs were subjected to polytrauma, followed by resuscitation (ATLS® guidelines) and operation of the femur fracture (intramedullary nailing technique). The pigs were allocated to combined C5 and CD14 inhibition therapy group (n=4) and control group (n=8). The therapy group received intravenously C5 inhibitor (RA101295) and anti-CD14 antibody (rMil2) 30 min post-trauma. Controls received saline. Combined C5 and CD14 inhibition reduced the blood levels of the terminal complement complex (TCC) by 70% (p=0.004), CRP by 28% (p=0.004), and IL-6 by 52% (p=0.048). The inhibition therapy prevented the platelet consumption by 18% and TAT formation by 77% (p=0.008). Moreover, the norepinephrine requirements in the treated group were reduced by 88%. The inhibition therapy limited the organ damage, thereby reducing the blood lipase values by 50% (p=0.028), LDH by 30% (p=0.004), AST by 33%, and NGAL by 30%. Immunofluorescent analysis of the lung tissue revealed C5b-9 deposition on blood vessels in five from the untreated, and in none of the treated animals. In kidney and liver, the C5b-9 deposition was similarly detected mainly the untreated as compared to the treated animals. Combined C5 and CD14 inhibition limited the inflammatory response, the organ damage, and reduced the catecholamine requirements after experimental polytrauma and might be a promising therapeutic approach.

Abstract
RATIONALE Cardiac arrest due to thyroid storm is a very rare clinical feature with high mortality that presents as multiorgan dysfunction. The mortality rate under this condition is close to 30%, even with appropriate treatment. Most thyroid storms occur in patients with long-standing untreated hyperthyroidism. PATIENT CONCERNS A 67-year-old woman, who had no specific medical history, was admitted with stupor mentality after a pedestrian traffic accident. DIAGNOSIS The patient had a Burch and Wartofsky score of 80, well beyond the criteria for diagnosis of a thyroid storm (>45 points). INTERVENTIONS Venoarterial extracorporeal membrane oxygenation (ECMO) was performed due to persistent unstable vital signs and findings of right ventricular dysfunction after return of spontaneous circulation after cardiopulmonary resuscitation. Circulatory assist with ECMO was performed for 8 days using a beta blocker, steroids, thionamide, and Lugol iodine solution. OUTCOMES Myocardial function and thyroid hormone levels were rapidly normalized. The patient's mental state recovered, and patient was discharged on day 36 maintaining medication. LESSONS Diagnosis of a thyroid storm in patients with multiple trauma is very difficult, because most trauma patients have symptoms of tachycardia, altered mental status, and abdominal pain that appear in thyrotoxic events. However, when unexplained shock without bleeding evidence occurs in patients with multiple trauma, a thyroid function test should be performed to rule out thyroid storm. Moreover, if hyperthyroidism is observed in a trauma patient, even if there is no history of hyperthyroidism, the possibility of a thyroid storm must be considered along with medical support treatment such as ECMO in patient with cardiogenic shock.

Abstract
Background and objective: Platelets contribute to the immunological response after multiple trauma. To determine the clinical impact, this study analyzes the association between platelets and creatinine concentration as an indicator of kidney function in polytraumatized patients. Methods: We investigated all patients presenting an Injury Severity Score (ISS) ≥16 for a 2-year period at our trauma center. Platelet counts and creatinine concentrations were analyzed, and correlation analysis was performed within 10 days after multiple trauma. Results: 83 patients with a median ISS of 22 were included. Platelet count was decreased on day 3 (p ≤ 0.001) and increased on day 10 (p ≤ 0.001). Platelet count was elevated on day 10 in younger patients and diminished in severely injured patients (ISS ≥35) on day 1 (p = 0.012) and day 3 (p = 0.011). Creatinine concentration was decreased on day 1 (p = 0.003) and day 10 (p ≤ 0.001) in female patients. Age (p = 0.01), male sex (p = 0.004), and injury severity (p = 0.014) were identified as factors for increased creatinine concentration on day 1, whereas platelets (p = 0.046) were associated with decreased creatinine concentrations on day 5 after multiple trauma. Conclusions: Kinetics of platelet count and creatinine concentration are influenced by age, gender, and trauma severity. There was no clear correlation between platelet counts and creatinine concentration. However, platelets seem to have a modulating effect on creatinine concentrations in the vulnerable phase after trauma.

Abstract
IntroductionOccult hypoperfusion (OH) is defined as persistent lactic acidosis despite normalization of vital parameters following trauma. The aim of this study was to analyze the association of occult hypoperfusion with local circulation and inflammation of injured soft tissue in a porcine polytrauma model.MethodsThis experimental study was performed with male landrace pigs who suffered a standardized polytrauma, including a femoral fracture, blunt chest trauma, liver laceration and a mean arterial pressure (MAP) controlled hemorrhagic shock. One hour after induction of trauma, the animals were resuscitated with retrograde femoral nailing, liver packing and volume replacement. Animals were stratified into Group Norm (normalizing lactate levels after resuscitation) and Group occult hypoperfusion (OH) (persistent lactate levels above 2 mmol/l with normalizing vital parameters after resuscitation). Local circulation (oxygen saturation, hemoglobin amount, blood flow) was measured with optical sensors at the subcutaneous soft tissue at the fractured extremity as well as at the stomach and colon. Local inflammatory parameters [interleukin (IL) 6, 8, 10, and heat shock protein (HSP)] were analyzed in the subcutaneous tissue of the fractured extremity.ResultsGroup Norm (n = 19) and Group OH (n = 5) were comparable in baseline vital and laboratory parameters. The shock severity and total amount of blood loss were comparable among Group Norm and Group OH. Following resuscitation Group OH had significantly lower local relative hemoglobin amount at the injured soft tissue of the fractured extremity when compared with Group Norm (39.4, SD 5.3 vs. 63.9, SD 27.6 A.U., p = 0.031). The local oxygenation was significantly lower in Group OH compared to Group Norm (60.4, SD 4.6 vs. 75.8, SD 12.8, p = 0.049). Local IL-6 in the fatty tissue was significantly higher in Group OH (318.3, SD 326.6 [pg/ml]) when compared with Group Norm (73.9,SD 96.3[pg/ml], p = 0.03). The local circulation at the abdominal organs was comparable in both groups.ConclusionOH is associated with decreased local circulation and increased local inflammation at the injured soft tissue of the extremity in polytrauma. OH might reflect the severity of local soft tissue injuries, and guide treatment strategies.

Abstract
OBJECTIVE To identify early prognostic factors that lead to an increased risk of unfavorable prognosis. DESIGN Observational cohort study from October 2002 to October 2017. SETTING AND PATIENTS Patients with severe TBI admitted to intensive care were included. VARIABLES AND INTERVENTIONS Epidemiological, clinical, analytical and therapeutic variables were collected. The functional capacity of the patient was assessed at 6 months using the Glasgow Outcome Scale (GOS). An unfavorable prognosis was considered a GOS less than or equal to 3. A univariate analysis was performed to compare the groups with good and bad prognosis and their relationship with the different variables. A multivariate analysis was performed to predict the patient's prognosis. RESULTS 98 patients were included, 61.2% males, median age 6.4 years (IQR 2.49-11.23). 84.7% were treated by the out-of-hospital emergency services. At 6 months, 51% presented satisfactory recovery, 26.5% moderate sequelae, 6.1% severe sequelae, and 2% vegetative state. 14.3% died. Statistical significance was found between the score on the prehospital Glasgow coma scale, pupillary reactivity, arterial hypotension, hypoxia, certain analytical and radiological alterations, such as compression of the basal cisterns, with an unfavorable prognosis. The multivariate analysis showed that it is possible to make predictive models of the evolution of the patients. CONCLUSIONS it is possible to identify prognostic factors of poor evolution in the first 24 h after trauma. Knowledge of them can help clinical decision-making as well as offer better information to families.

Abstract
<b>Introduction:</b> Injuries of the carotid artery constitute a rare group of injuries. This study presents results of the treatment of 44 patients with iatrogenic carotid artery injuries for over 20 years. The patients were treated by the team of doctors of the Department of Vascular, General and Transplant Surgery in Wroclaw in the years 1997-2017 (Head of the Department Prof. Klemens Skóra, MD, and Prof. Piotr Szyber, MD, PhD - material used with permission). </br></br> <b>Aim:</b> Aims of the analysis are: to estimate the frequency of different forms of iatrogenic injuries to the common and internal carotid artery, to evaluate the results of treatment, to assess the most effective surgical method depending on the type of injury, and develop an effective preoperative, intraoperative and postoperative regimen.</br></br> <b>Discussion and results:</b> The frequency of various carotid artery injuries (blunt, acute, traffic) was constant between years, but the number of iatrogenic injuries definitely increased over time. The prognosis for patients with carotid artery injury, especially when combined with multi-organ trauma, is the gravest. Significantly better treatment results were achieved with both acute and iatrogenic injuries. This is mainly due to easier and quicker diagnosis and better conditions for assisting patients.</br></br> <b>Conclusions:</b> In iatrogenic injuries, a well-designed surgical scheme, i.e. primarily the administration of UTH and placing a temporary flow drain by the first operating team, reduces the risk of neurological complications.

Abstract
BACKGROUND For identifying hemorrhagic shock in trauma patients, some objective data are needed. The use of base excess (BE) and lactate values have been originated. In this study, it was aimed to determine the usability of end tidal carbon dioxide (ETCO₂) in patients with multiple trauma for recognizing hemorrhagic shock. METHODS Patients who were admitted to the emergency department between June 2019 and February 2020 with highenergy multiple trauma were included in the study. ETCO₂ and BE values were measured. Correlation coefficients were calculated to determine correlations between ETCO₂ and BE levels. RESULTS One hundred and twenty-two patients were included in the study. Eighty-nine (73%) were men and 33 (27%) were women, and the mean age of the study population was 38.70 ± 19.18. The mortality rate was 14.8% in the study population. The correlation between ETCO₂ and BE values was significant (r: 0.27) and in the same range in the Bland-Altmann analysis. ETCO₂ levels above 35 were specific for stage 1 hemorrhagic shock. ETCO2 levels below 30 were sensitive for stage 2 and 3 hemorrhagic shocks and when the levels were measured below 22 it was found specific for stage 4 shock. The specificity increased to 99% at levels below 18. The sensitivity for ETCO₂ values below 22 for predicting mortality was 33.33%, the specificity was 89.42%, the positive predictive value was 35.29% and the negative predictive value was 88.57%. The sensitivity for BE values below -10 for predicting mortality was 50%, the specificity was 93.27%, the positive predictive value was 56.25% and the negative predictive value was 91.51%.

Abstract
OBJECTIVE The aim: To study the influence of chronic heart failure of different origin on the energetics of blood circulation in case of polytrauma without myocardial damage. PATIENTS AND METHODS Materials and methods: 32 patients with polytrauma without myocardial injury were examined that was assessed by the level of Troponin I not exceeding 0.3 ng/ml. The patients were divided into two groups: 1st group (n=15) without chronic heart failure (CHF), and the 2nd one - with CHF. The absence of CHF was proved by the level of NT-proBNP not exceeding 90 pg/ml. Circulatory reserve (CR) was an integral energy index. All measurements were made at the patients' admittance to the hospital, on the 3rd and the 7th day after admittance. RESULTS Results: During admittance, CR in the groups was low without a significant difference (in the 1st group - 117±44, in the 2nd group - 99±39 mW/m2, p = 0.2). CR was increasing in the 1st group quicker than in the 2nd one; on the seventh day it reached 414±128 mW/m2 growing out of dangerous values, while the 2nd group showed only up to 295±96 mW/m2 (p = 0.005), which is lower than reference values. CONCLUSION Conclusions: A severer disorder occurs in patients with initial CHF. The treatment requires the improvement of myocardium metabolism. An important prognosis criterium of severity can be represented by the level of circulatory reserve; its value below 100-120 mW/m2 is a worse outcome predictor.

Abstract
BACKGROUND Although 17α-ethinyl estradiol-3-sulfate (EES) reduces mortality in animal models of controlled hemorrhage, its role in a clinically relevant injury model is unknown. We assessed the impact of EES in a swine model of multiple injuries and hemorrhage. METHODS The study was performed under Good Laboratory Practice, with 30 male uncastrated swine (25-50 kg) subjected to tibial fracture, pulmonary contusion, and 30% controlled hemorrhage for an hour. Animals were randomized to one of five EES doses: 0 (control), 0.3, 1, 3, and 5 mg/kg, administered postinjury. Subjects received no resuscitation and were observed for 6 hours or until death. Survival data were analyzed using Cox-proportional hazard regression. Left ventricular pressure-volume loops were used to derive preload recruitable stroke work as a measure of cardiac inotropy. Immediate postinjury preload recruitable stroke work values were compared with values at 1 hour post-drug administration. RESULTS Six-hour survival for the 0, 0.3, 1, 3, and 5 mg/kg groups was 0%, 50%, 33.3%, 16.7%, and 0%, respectively. Following Cox regression, the hazard (95% confidence interval) of death was significantly reduced in the 0.3 (0.22 [0.05-0.93]) and 1 (0.24 [0.06-0.89]) mg/kg groups but not the 3 (0.49 [0.15-1.64]) and 5 (0.46 [0.14-1.47]) mg/kg groups. Mean survival time was significantly extended in the 1 mg/kg group (246 minutes) versus the 0 mg/kg group (96 minutes) (p = 0.04, t test). At 1 hour post-drug administration, inotropy was significantly higher than postinjury values in the 0.3 and 1 mg/kg groups (p = 0.003 and p < 0.001, respectively). Inotropy was unchanged in the 3 and 5 mg/kg groups but significantly depressed in the control (p = 0.022). CONCLUSION Administration of EES even in the absence of fluid resuscitation reduces mortality and improves cardiac inotropy in a clinically relevant swine model of multiple injuries and hemorrhage. These findings support the need for a clinical trial in human trauma patients.

Abstract
Trauma is the leading cause of death in individuals under 44 years of age. Thorax trauma (TxT) is strongly associated with trauma-related death, an unbalanced innate immune response, sepsis, acute respiratory distress syndrome, and multiple organ dysfunction. It is shown that different in vivo traumata, such as TxT or an in vitro polytrauma cytokine cocktail trigger secretion of small extracellular nanovesicles (sEVs) from endothelial cells with pro-inflammatory cargo. These sEVs transfer transcripts for ICAM-1, VCAM-1, E-selectin, and cytokines to systemically activate the endothelium, facilitate neutrophil-endothelium interactions, and destabilize barrier integrity. Inhibition of sEV-release after TxT in mice ameliorates local as well as systemic inflammation, neutrophil infiltration, and distant organ damage in kidneys (acute kidney injury, AKI). Vice versa, injection of TxT-plasma-sEVs into healthy animals is sufficient to trigger pulmonary and systemic inflammation as well as AKI. Accordingly, increased sEV concentrations and transfer of similar cargos are observed in polytrauma patients, suggesting a fundamental pathophysiological mechanism.

Abstract
INTRODUCTION Tranexamic acid (TXA) has shown to be beneficial in selected patients with hemorrhagic shock. Recently, TXA has gained interest in isolated traumatic brain injury (TBI) patients with variable results. There are limited data on TXA in polytrauma with associated TBI. This study investigated the role of TXA in severely injured patients with associated severe TBI. METHODS A 7.5-year prospective cohort study was performed to investigate the relation between prehospital TXA and mortality in consecutive trauma patients with associated severe TBI (Abbreviated Injury Scale (AIS)head ≥ 3) admitted to a Level-1 Trauma Center ICU. Indication for prehospital TXA administration was (suspicion of) hemorrhagic shock, and/or systolic blood pressure (SBP) ≤ 90 mmHg. Demographics, data on physiology, resuscitation, and outcomes were prospectively collected. RESULTS Two hundred thirty-four patients (67% males) with median age of 49 years and ISS 33 (98% blunt injuries) were included. Thirteen patients (6%) developed thromboembolic complications; mortality rate was 24%. Fifty-one percent of patients received prehospital TXA. TXA patients were younger, had more deranged physiology on arrival, and received more crystalloids and blood products ≤ 24 h. There was, however, no difference in overall outcome between TXA patients and no-TXA patients. CONCLUSIONS Despite having a more deranged physiology TXA patients had similar outcome compared to no-TXA patients who were much older. Thromboembolic complication rate was low. Prehospital tranexamic acid has no evident effect on outcome in polytrauma patients with associated critical brain injury.

Abstract
BACKGROUND After severe trauma, the older host experiences more dysfunctional hematopoiesis of bone marrow (BM) hematopoietic stem and progenitor cells (HSPCs), and dysfunctional differentiation of circulating myeloid cells into effective innate immune cells. Our main objective was to compare BM HSPC microRNA (miR) responses of old and young mice in a clinically relevant model of severe trauma and shock. METHODS C57BL/6 adult male mice aged 8 to 12 weeks (young) and 18 to 24 months (old) underwent multiple injuries and hemorrhagic shock (polytrauma [PT]) that engenders the equivalent of major trauma (Injury Severity Score, >15). Pseudomonas pneumonia (PNA) was induced in some young and old adult mice 24 hours after PT. MicroRNA expression patterns were determined from lineage-negative enriched BM HSPCs isolated from PT and PT-PNA mice at 24 and 48 hours postinjury, respectively. Genome-wide expression and pathway analyses were also performed on bronchoalveolar lavage (BAL) leukocytes from both mouse cohorts. RESULTS MicroRNA expression significantly differed among all experimental conditions (p < 0.05), except for old-naive versus old-injured (PT or PT-PNA) mice, suggesting an inability of old mice to mount a robust early miR response to severe shock and injury. In addition, young adult mice had significantly more leukocytes obtained from their BAL, and there were greater numbers of polymorphonuclear cells compared with old mice (59.8% vs. 2.2%, p = 0.0069). Despite increased gene expression changes, BAL leukocytes from old mice demonstrated a more dysfunctional transcriptomic response to PT-PNA than young adult murine BAL leukocytes, as reflected in predicted upstream functional pathway analysis. CONCLUSION The miR expression pattern in BM HSPCs after PT (+/-PNA) is dissimilar in old versus young adult mice. In the acute postinjury phase, old adult mice are unable to mount a robust miR HSPC response. Hematopoietic stem and progenitor cell miR expression in old PT mice reflects a diminished functional status and a blunted capacity for terminal differentiation of myeloid cells.

Abstract
BACKGROUND Aeromedical evacuation can expose traumatically injured patients to low pressure (hypobaria) and hypoxia. Here, we sought to assess the impact of hypobaria on inflammation, organ injury, and mortality in a mouse model of polytrauma. METHODS Eight to 12-week-old male C57BL/6J mice were subjected to sham or polytrauma consisting of bowel ischemia by superior mesenteric artery occlusion, hindlimb muscle crush, and tibia fracture. Two hours after injury, animals were randomized to undergo either 6 h of hypobaria or sea-level, room air conditions. At 8 or 24 h after injury, transthoracic echocardiography was performed. Acute kidney injury (AKI) biomarkers were measured by qRT-PCR. Plasma cytokine and endothelial injury markers were determined by enzyme-linked immunosorbent assay. RESULTS Eight hours after traumatic injury, mice exhibited a marked increase in plasma IL-6 (57 pg/mL vs. 1,216 pg/mL), AKI with increased Ngal and Kim-1, and endothelial injury as evidenced by significantly increased plasma hyaluronic acid (96 ng/mL vs.199 ng/mL), thrombomodulin (23.2 ng/mL vs. 58.9 ng/mL), syndecan-1 (0.99 ng/mL vs. 4.34 ng/mL), and E-selectin (38.6 ng/mL vs. 62.7 ng/mL). The trauma mice also developed cardiac dysfunction with decreased cardiac output and stroke volume at 8 h postinjury. Hypobaric exposure after polytrauma led to decreased ejection fraction (81.0% vs. 74.2%, P < 0.01) and increased plasma hyaluronic acid (199 ng/mL vs. 260 ng/mL, P < 0.05), thrombomodulin (58.9 ng/mL vs. 75.4 ng/mL, P < 0.05), and syndecan-1 (4.34 ng/mL vs. 8.33 ng/mL, P < 0.001) at 8 h postinjury. CONCLUSIONS Hypobaria exposure appeared to worsen cardiac dysfunction and endothelial injury following polytrauma and thus may represent a physiological "second hit" following traumatic injury.

Abstract
CASE We report 2 patients who were involved in high-velocity road traffic accidents. Both these patients had congenital pubic diastasis with very subtle clinical and radiological signs that were misdiagnosed as posttraumatic diastasis on initial radiographic evaluation. CONCLUSION Trauma surgeons should be aware of this anomaly because congenital pubic diastasis could present without any major clinical signs and could easily be mistaken for a traumatic diastasis.
