Abstract
INTRODUCTION Ventilation of major trauma patients is often needed in both the acute (emergency department and early ICU phase) and subsequent phases of trauma care for those who need ICU admission. What is unclear is whether ICU ventilation strategies should be directly extrapolated to the acute phase of treatment. METHODS This paper reviews the ARDS.net study, highlights recent developments in ventilation strategies, and provides practical ventilation guidance to the trauma surgeon for acute phase (in the ED or ICU) and the subsequent phase of ICU care. RESULTS The acute phase of care in the ED and the ICU is different from the subsequent phases of ICU care as the lung is more recruitable and there are other aspects of resuscitation from metabolic acidosis and traumatic brain injury, which require a different ventilation strategy to the traditional ARDS.net approach. DISCUSSION AND CONCLUSION The acute phase is different from the subsequent phase of care and there appears to be some inappropriate extrapolation of ICU practice to the acute phase. Application of the proposed ventilation strategies should ensure an optimal outcome. It is important to treat patients as individuals during assessment and treatment.

Abstract
Intra-abdominal infections (IAIs) are common surgical emergencies and have been reported as major contributors to non-trauma deaths in the emergency departments worldwide. The cornerstones of effective treatment of IAIs are early recognition, adequate source control, and appropriate antimicrobial therapy. Prompt resuscitation of patients with ongoing sepsis is of utmost important. In hospitals worldwide, non-acceptance of, or lack of access to, accessible evidence-based practices and guidelines result in overall poorer outcome of patients suffering IAIs. The aim of this paper is to promote global standards of care in IAIs and update the 2013 WSES guidelines for management of intra-abdominal infections.

Abstract
Acute appendicitis (AA) is among the most common cause of acute abdominal pain. Diagnosis of AA is challenging; a variable combination of clinical signs and symptoms has been used together with laboratory findings in several scoring systems proposed for suggesting the probability of AA and the possible subsequent management pathway. The role of imaging in the diagnosis of AA is still debated, with variable use of US, CT and MRI in different settings worldwide. Up to date, comprehensive clinical guidelines for diagnosis and management of AA have never been issued. In July 2015, during the 3rd World Congress of the WSES, held in Jerusalem (Israel), a panel of experts including an Organizational Committee and Scientific Committee and Scientific Secretariat, participated to a Consensus Conference where eight panelists presented a number of statements developed for each of the eight main questions about diagnosis and management of AA. The statements were then voted, eventually modified and finally approved by the participants to The Consensus Conference and lately by the board of co-authors. The current paper is reporting the definitive Guidelines Statements on each of the following topics: 1) Diagnostic efficiency of clinical scoring systems, 2) Role of Imaging, 3) Non-operative treatment for uncomplicated appendicitis, 4) Timing of appendectomy and in-hospital delay, 5) Surgical treatment 6) Scoring systems for intra-operative grading of appendicitis and their clinical usefulness 7) Non-surgical treatment for complicated appendicitis: abscess or phlegmon 8) Pre-operative and post-operative antibiotics.

Abstract
Transfusion of autologous blood, recovered from the surgical field, has been widely accepted for use in elective cases with significant blood loss. The use of these techniques in the setting of exsanguinating traumatic haemorrhage has been limited, however, by a number of confounding issues. These include: (a) the potential for increased infectious complications resulting from the reinfusion of blood from a contaminated field; (b) the risk of exacerbating a consumptive coagulopathy; (c) a potential increased risk of multiple organ failure syndrome due to the infusion of cytokines and activated inflammatory mediators; (d) the practicality and logistics of this approach in the moribund patient; and (e) the cost-effectiveness of this technology. The purpose of this review is to evaluate the current literature addressing these issues and better define the role for autologous transfusion in the trauma population.

Abstract
Acute calculus cholecystitis is a very common disease with several area of uncertainty. The World Society of Emergency Surgery developed extensive guidelines in order to cover grey areas. The diagnostic criteria, the antimicrobial therapy, the evaluation of associated common bile duct stones, the identification of “high risk” patients, the surgical timing, the type of surgery, and the alternatives to surgery are discussed. Moreover the algorithm is proposed: as soon as diagnosis is made and after the evaluation of choledocholitiasis risk, laparoscopic cholecystectomy should be offered to all patients exception of those with high risk of morbidity or mortality. These Guidelines must be considered as an adjunctive tool for decision but they are not substitute of the clinical judgement for the individual patient.

Abstract
Introduction Trauma systems were developed to improve the care for the injured. The designation and elements comprising these systems vary across countries. In this study, we have compared the demographic patterns and patient outcomes of Level I trauma centers in three international trauma systems. Methods International multicenter prospective trauma registry-based study, performed in the University Medical Center Utrecht (UMCU), Utrecht, the Netherlands, John Hunter Hospital (JHH), Newcastle, Australia, and Harborview Medical Center (HMC), Seattle, the United States. Inclusion: patients ≥18 years, admitted in 2012, registered in the institutional trauma registry. Results In UMCU, JHH, and HMC, respectively, 955, 1146, and 4049 patients met the inclusion criteria of which 300, 412, and 1375 patients with Injury Severity Score (ISS) > 15. Mean ISS was higher in JHH (13.5; p < 0.001) and HMC (13.4; p < 0.001) compared to UMCU (11.7). Unadjusted mortality: UMCU = 6.5 %, JHH = 3.6 %, and HMC = 4.8 %. Adjusted odds of death: JHH = 0.498 [95 % confidence interval (CI) 0.303–0.818] and HMC = 0.473 (95 % CI 0.325–0.690) compared to UMCU. HMC compared to JHH was 1.002 (95 % CI 0.664–1.514). Odds of death patients ISS > 15: JHH = 0.507 (95 % CI 0.300–0.857) and HMC = 0.451 (95 % CI 0.297–0.683) compared to UMCU. HMC = 0.931 (95 % CI 0.608–1.425) compared to JHH. TRISS analysis: UMCU: Ws = 0.787, Z = 1.31, M = 0.87; JHH, Ws = 3.583, Z = 6.7, M = 0.89; HMC, Ws = 3.902, Z = 14.6, M = 0.84. Conclusion This study demonstrated substantial differences across centers in patient characteristics and mortality, mainly of neurological cause. Future research must investigate whether the outcome differences remain with nonfatal and long-term outcomes. Furthermore, we must focus on the development of a more valid method to compare systems.

Abstract
Intra-abdominal infections (IAI) are an important cause of morbidity and are frequently associated with poor prognosis, particularly in high-risk patients. The cornerstones in the management of complicated IAIs are timely effective source control with appropriate antimicrobial therapy. Empiric antimicrobial therapy is important in the management of intra-abdominal infections and must be broad enough to cover all likely organisms because inappropriate initial antimicrobial therapy is associated with poor patient outcomes and the development of bacterial resistance. The overuse of antimicrobials is widely accepted as a major driver of some emerging infections (such as C. difficile), the selection of resistant pathogens in individual patients, and for the continued development of antimicrobial resistance globally. The growing emergence of multi-drug resistant organisms and the limited development of new agents available to counteract them have caused an impending crisis with alarming implications, especially with regards to Gram-negative bacteria. An international task force from 79 different countries has joined this project by sharing a document on the rational use of antimicrobials for patients with IAIs. The project has been termed AGORA (Antimicrobials: A Global Alliance for Optimizing their Rational Use in Intra-Abdominal Infections). The authors hope that AGORA, involving many of the world's leading experts, can actively raise awareness in health workers and can improve prescribing behavior in treating IAIs.

Abstract
PURPOSE The purpose of this study was to determine the proportion of children who survived after emergency department thoracotomy (EDT) for blunt trauma using a national database. METHODS A review of the National Trauma Data Bank was performed for years 2007-2012 to identify children <18 years of age who underwent EDT for blunt trauma. RESULTS Eighty-four children <18 years of age underwent EDT after blunt trauma. Every child died during their hospitalization. The median age was 15 (IQR 6-17) years. Mean injury severity score (ISS) was 34.2 (SD 20.8), and 56% had an ISS of 26-75. Data for "signs of life" were available for 21 children. Fifteen (71%) had signs of life upon ED arrival. Sixty percent of children died in the ED. Of those who survived to the operating room (OR), 66% died in the OR. Four children (5%) survived more than 24 hours in the intensive care unit, three of whom had a maximum head abbreviated injury score of 5. CONCLUSION There were no survivors after EDT for blunt trauma in the pediatric population in this national dataset. Usual indicators for EDT after blunt trauma in adults may not apply in children, and use should be discouraged without compelling evidence of a reversible cause of extremis.

Abstract
IMPORTANCE Necrotizing soft-tissue infections (NSTI) have high morbidity and mortality rates despite aggressive surgical debridement and antibiotic therapy. AB103 is a peptide mimetic of the T-lymphocyte receptor, CD28. We hypothesized that AB103 will limit inflammatory responses to bacterial toxins and decrease the incidence of organ failure. OBJECTIVES To establish the safety of AB103 in patients with NSTI and evaluate the potential effects on clinically meaningful parameters related to the disease. DESIGN, SETTING, AND PARTICIPANTS A prospective, randomized, placebo-controlled, double-blinded study was performed in 6 academic medical centers in the United States. Participants included adults with NSTI. Of 345 patients screened, 43 were enrolled for the intent-to-treat analysis, and 40 met criteria for the modified intent-to-treat analysis; 15 patients each were included in the high-dose and low-dose treatment arms, and 10 in the placebo arm. INTERVENTION Single intravenous dose of AB103 (0.5 or 0.25 mg/kg) within 6 hours after diagnosis of NSTI. MAIN OUTCOMES AND MEASURES Change in the Sequential Organ Failure Assessment score within 28 days, intensive care unit-free and ventilator-free days, number and timing of debridements, plasma and tissue cytokine levels at 0 to 72 hours, and adverse events. RESULTS Baseline characteristics were comparable in the treatment groups. The Sequential Organ Failure Assessment score improved from baseline in both treatment groups compared with the placebo group at 14 days (change from baseline score, -2.8 in the high-dose, -2 in the low-dose, and +1.3 in the placebo groups; P = .04). AB103-treated patients had a similar number of debridements (mean [SD], 2.2 [1.1] for the high-dose, 2.3 [1.2] for the low-dose, and 2.8 [2.1] for the placebo groups; P = .56). There were no statistically significant differences in intensive care unit-free and ventilator-free days or in plasma and tissue cytokine levels. No drug-related adverse events were detected. CONCLUSIONS AND RELEVANCE AB103 is a safe, promising new agent for modulation of inflammation after NSTI. Further study is warranted to establish efficacy. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01417780.

Abstract
OBJECTIVES Acute traumatic coagulopathy is associated with adverse outcomes including death. Previous studies examining acute traumatic coagulopathy's relation with mortality are limited by inconsistent criteria for syndrome diagnosis, inadequate control of confounding, and single-center designs. In this study, we validated the admission international normalized ratio as an independent risk factor for death and other adverse outcomes after trauma and compared two common international normalized ratio-based definitions for acute traumatic coagulopathy. DESIGN Multicenter prospective observational study. SETTING Nine level I trauma centers in the United States. PATIENTS A total of 1,031 blunt trauma patients with hemorrhagic shock. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS International normalized ratio exhibited a positive adjusted association with all-cause in-hospital mortality, hemorrhagic shock-associated in-hospital mortality, venous thromboembolism, and multiple organ failure. Acute traumatic coagulopathy affected 50% of subjects if defined as an international normalized ratio greater than 1.2 and 21% of subjects if defined by international normalized ratio greater than 1.5. After adjustment for potential confounders, acute traumatic coagulopathy defined as an international normalized ratio greater than 1.5 was significantly associated with all-cause death (odds ratio [OR], 1.88; p < 0.001), hemorrhagic shock-associated death (OR, 2.44; p = 0.001), venous thromboembolism (OR, 1.73; p < 0.001), and multiple organ failure (OR, 1.38; p = 0.02). Acute traumatic coagulopathy defined as an international normalized ratio greater than 1.2 was not associated with an increased risk for the studied outcomes. CONCLUSIONS Elevated international normalized ratio on hospital admission is a risk factor for mortality and morbidity after severe trauma. Our results confirm this association in a prospectively assembled multicenter cohort of severely injured patients. Defining acute traumatic coagulopathy by using an international normalized ratio greater than 1.5 but not an international normalized ratio greater than 1.2 identified a clinically meaningful subset of trauma patients who, adjusting for confounding factors, experienced more adverse outcomes. Targeting future therapies for acute traumatic coagulopathy to patients with an international normalized ratio greater than 1.5 may yield greater returns than using a lower international normalized ratio threshold.

Abstract
BACKGROUND Many general surgical residency programs lack a formal international component. We hypothesized that most surgery programs do not have international training or do not provide the information to prospective applicants regarding electives or programs in an easily accessible manner via Web-based resources. MATERIALS AND METHODS Individual general surgery program Web sites and the American College of Surgeons residency tool were used to identify 239 residencies. The homepages were examined for specific mention of international or global health programs. Ease of access was also considered. Global surgery specific pages or centers were noted. Programs were assessed for length of rotation, presence of research component, and mention of benefits to residents and respective institution. RESULTS Of 239 programs, 24 (10%) mentioned international experiences on their home page and 42 (18%) contained information about global surgery. Of those with information available, 69% were easily accessible. Academic programs were more likely than independent programs to have information about international opportunities on their home page (13.7% versus 4.0%, P = 0.006) and more likely to have a dedicated program or pathway Web site (18.8% versus 2.0%, P < 0.0001). Half of the residencies with global surgery information did not have length of rotation available. Research was only mentioned by 29% of the Web sites. Benefits to high-income country residents were discussed more than benefits to low- and middle-income country residents (57% versus 17%). CONCLUSIONS General surgery residency programs do not effectively communicate international opportunities for prospective residents through Web-based resources and should seriously consider integrating international options into their curriculum and better present them on department Web sites.

Abstract
BACKGROUND Surgical intervention for severe traumatic brain injury (TBI) caused by extra-axial hemorrhage has declined in recent decades. The effect of this change on patient outcomes is unknown. OBJECTIVE To determine the change over time in surgical intervention in this population and to assess changes in patient outcomes. METHODS In this retrospective cohort study, the Washington State Trauma Registry was queried from 1995 to 2012 for patients with extra-axial hemorrhage and head Abbreviated Injury Scale score of 3 to 5. Data were linked to the state-wide death registry to analyze long-term mortality. The primary outcome was inpatient mortality. Secondary outcomes included 6- and 12-month mortality and modified Functional Independence Measure at discharge. Multivariable analyses were completed for all outcomes. RESULTS A total of 22974 patients met inclusion criteria. Over the study period, surgical intervention for severe TBI declined from 36% to 7%. There was a decline in case fatality from 22% to 12%. In 2012, the relative risk of inpatient mortality was 23% lower compared with 1995 (adjusted mortality risk ratio, 0.77; 95% confidence interval, 0.63-0.94). Changes in 6- and 12-month adjusted mortality and modified Functional Independence Measure were not statistically significant. CONCLUSION The decline in surgical intervention for severe TBI caused by extra-axial hemorrhage in Washington State was ubiquitous across regional, demographic, and injury characteristic strata. There was concurrently a reduction in inpatient mortality in this population. Functional status and long-term mortality, however, have remained the same. Future studies are needed to better identify modifiable risk factors for improvement in functional status and long-term mortality in this population.

Abstract
INTRODUCTION We wished to characterize the relationship of advanced age to clinical outcomes and to transcriptomic responses after severe blunt traumatic injury with hemorrhagic shock. METHODS We performed epidemiological, cytokine, and transcriptomic analyses on a prospective, multi-center cohort of 1,928 severely injured patients. RESULTS We found that there was no difference in injury severity between the aged (age ≥55, n = 533) and young (age <55, n = 1395) cohorts. However, aged patients had more comorbidities. Advanced age was associated with more severe organ failure, infectious complications, ventilator days, and intensive care unit length of stay, as well as, an increased likelihood of being discharged to skilled nursing or long-term care facilities. Additionally, advanced age was an independent predictor of a complicated recovery and 28-day mortality. Acutely after trauma, blood neutrophil genome-wide expression analysis revealed an attenuated transcriptomic response as compared to the young; this attenuated response was supported by the patients' plasma cytokine and chemokine concentrations. Later, these patients demonstrated gene expression changes consistent with simultaneous, persistent pro-inflammatory and immunosuppressive states. CONCLUSIONS We concluded that advanced age is one of the strongest non-injury related risk factors for poor outcomes after severe trauma with hemorrhagic shock and is associated with an altered and unique peripheral leukocyte genomic response. As the general population's age increases, it will be important to individualize prediction models and therapeutic targets to this high risk cohort.

Abstract
OBJECTIVES Bacteremic trauma victims have a higher risk of death than their nonbacteremic counterparts. The role that altered immunity plays in the development of bacteremia is unknown. Using an existing dataset, we sought to determine if differences in early postinjury immune-related gene expression are associated with subsequent Gram-negative bacteremia. DESIGN Retrospective cohort study, a secondary analysis of the Glue Grant database. SETTING Seven level I trauma centers across the United State. SUBJECTS Severely injured blunt trauma patients. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Total leukocyte gene expression was compared between the subjects in whom Gram-negative bacteremia developed and those in whom it did not develop. We observed that Gram-negative bacteremia was an independent risk factor for death (odds ratio, 1.86; p = 0.015). We then compared gene expression at 12 and 96 hours after injury in 10 subjects in whom subsequently Gram-negative bacteremia developed matched to 26 subjects in whom it did not develop. At 12 hours, expression of 64 probes differed more than or equal to 1.5-fold; none represented genes related to innate or adaptive immunity. By 96 hours, 102 probes were differentially expressed with 20 representing 15 innate or adaptive immunity genes, including down-regulation of IL1B and up-regulation of IL1R2, reflecting suppression of innate immunity in Gram-negative bacteremia subjects. We also observed down-regulation of adaptive immune genes in the Gram-negative bacteremia subjects. CONCLUSIONS By 96 hours after injury, there are differences in leukocyte gene expression associated with the development of Gram-negative bacteremia, reflecting suppression of both innate and adaptive immunity. Gram-negative bacteremia after trauma is, in part, consequence of host immunity failure and may not be completely preventable by standard infection-control techniques.

Abstract
BACKGROUND Despite evidence that electronic medical record (EMR) information technology innovations can enhance the quality of trauma center care, few investigations have systematically assessed United States (US) trauma center EMR capacity, particularly for screening of mental health comorbidities. STUDY DESIGN Trauma programs at all US level I and II trauma centers were contacted and asked to complete a survey regarding health information technology (IT) and EMR capacity. RESULTS Three hundred ninety-one of 525 (74%) US level I and II trauma centers responded to the survey. More than 90% of trauma centers reported the ability to create custom patient tracking lists in their EMR. Forty-seven percent of centers were interested in automating a blood alcohol content screening process; only 14% reported successfully using their EMR to perform this task. Marked variation was observed across trauma center sites with regard to the types of EMR systems used as well as rates of adoption and turnover of EMR systems. CONCLUSIONS Most US level I and II trauma centers have installed EMR systems; however, marked heterogeneity exists with regard to EMR type, available features, and turnover. A minority of centers have leveraged their EMR for screening of mental health comorbidities among trauma inpatients. Greater attention to effective EMR use is warranted from trauma accreditation organizations.

Abstract
Inflammatory signaling pathways, such as p38 mitogen-activated protein kinase (MAPK) play a central role in host responses to injury. In previous studies by the authors, topical p38 MAPK inhibitors effectively attenuated inflammatory signaling in a partial-thickness scald burn model, when applied to the burn wound immediately after injury. However, clinically relevant full-thickness scald burn wounds may act as a barrier to topical immune modulators, and delayed application of topical p38 MAPK inhibitors may not be effective. In this study, the authors evaluate the efficacy of topical p38 MAPK inhibition on full-thickness scald burns with immediate and delayed treatment. C57/BL6 mice received "Sham" or 30% TBSA full-thickness scald burn injury. After injury, the burn wounds were treated with a topical p38 MAPK inhibitor or vehicle. The treatment group received topical p38 MAPK inhibitor either immediately after burn or 4 hours (delayed) after injury. All animals were killed at 12 or 24 hours. Burn wounds underwent histological analyses. Skin and plasma were analyzed by enzyme-linked immunosorbent assay or real-time quantitative polymerase chain reaction for cytokine expression. Full-thickness scald burns resulted from immersion in 62°C water for 25 seconds. Topical p38 MAPK inhibitor attenuated dermal interleukin (IL)-6, MIP-2, and IL-1β expression and plasma IL-6 and MIP-2 cytokine expression. In addition, delayed application of topical p38 MAPK inhibitors significantly reduced dermal and plasma cytokine expression compared with vehicle control. Topical p38 MAPK inhibitors remain potent in reducing full-thickness burn wound inflammatory signaling, even when treatment is delayed by several hours postinjury. Topical application of p38 MAPK inhibitor may be a clinically viable treatment after burn injury.

Abstract
PURPOSE Polymorphonuclear neutrophils (PMNs) play an important role in mediating the innate immune response after severe traumatic injury; however, the cellular proteome response to traumatic condition is still largely unknown. EXPERIMENTAL DESIGN We applied 2D-LC-MS/MS-based shotgun proteomics to perform comparative proteome profiling of human PMNs from severe trauma patients and healthy controls. RESULTS A total of 197 out of ~2500 proteins (being identified with at least two peptides) were observed with significant abundance changes following the injury. The proteomics data were further compared with transcriptomics data for the same genes obtained from an independent patient cohort. The comparison showed that the protein abundance changes for the majority of proteins were consistent with the mRNA abundance changes in terms of directions of changes. Moreover, increased protein secretion was suggested as one of the mechanisms contributing to the observed discrepancy between protein and mRNA abundance changes. Functional analyses of the altered proteins showed that many of these proteins were involved in immune response, protein biosynthesis, protein transport, NRF2-mediated oxidative stress response, the ubiquitin-proteasome system, and apoptosis pathways. CONCLUSIONS AND CLINICAL RELEVANCE Our data suggest increased neutrophil activation and inhibited neutrophil apoptosis in response to trauma. The study not only reveals an overall picture of functional neutrophil response to trauma at the proteome level, but also provides a rich proteomics data resource of trauma-associated changes in the neutrophil that will be valuable for further studies of the functions of individual proteins in PMNs.

Abstract
All surgeons want the best, safest care for their patients, but providing this requires the complex coordination of multiple disciplines to ensure that all elements of care are timely, appropriate, and well organized. Quality-improvement initiatives are beginning to lead to improvements in the quality of care and coordination amongst teams in the operating room. As the population ages and patients present with more complex disease pathology, the demands for efficient systematization will increase. Although evidence suggests that postoperative mortality rates are declining, there is substantial room for improvement. Multiple quality metrics are used as surrogates for safe care, but surgical teams--including surgeons, anaesthetists, and nurses--must think beyond these simple interventions if they are to effectively communicate and coordinate in the face of increasing demands.
