Abstract
Intra-abdominal infections (IAIs) are common surgical emergencies and have been reported as major contributors to non-trauma deaths in hospitals worldwide. The cornerstones of effective treatment of IAIs include early recognition, adequate source control, appropriate antimicrobial therapy, and prompt physiologic stabilization using a critical care environment, combined with an optimal surgical approach. Together, the World Society of Emergency Surgery (WSES), the Global Alliance for Infections in Surgery (GAIS), the Surgical Infection Society-Europe (SIS-E), the World Surgical Infection Society (WSIS), and the American Association for the Surgery of Trauma (AAST) have jointly completed an international multi-society document in order to facilitate clinical management of patients with IAIs worldwide building evidence-based clinical pathways for the most common IAIs. An extensive non-systematic review was conducted using the PubMed and MEDLINE databases, limited to the English language. The resulting information was shared by an international task force from 46 countries with different clinical backgrounds. The aim of the document is to promote global standards of care in IAIs providing guidance to clinicians by describing reasonable approaches to the management of IAIs.

Abstract
Background: Pancreatic trauma surgery is a complicated surgical procedure for severe pancreatic injuries, accompanied by a high incidence of complications and mortality. This study was designed to explore the long-term prognosis of pancreatic surgery because of abdominal trauma. Patients and Methods: The clinical data of 103 patients who were admitted to Jinling Hospital between August 2012 and August 2019 who had pancreatic trauma surgery were analyzed retrospectively. Results: All admissions involved pancreatic trauma surgery performed at an outside hospital network, which later transferred patients to our institution because of post-operative later-stage complications. Eight patients received American Association for the Surgery of Trauma (AAST) grade 1 or 2 pancreatic injuries and 95 received AAST grade 3, 4, or 5 pancreatic injuries. The primary surgical management of pancreatic injuries included drainage of the pancreatic injury (n = 28), repair of the pancreas (n = 35), partial pancreatectomy (n = 15), pancreaticojejunostomy (n = 6), and pancreaticoduodenectomy (n = 19). The most common mechanism of trauma was motor vehicle collision (n = 72), crush injury (n = 26), and stab wound (n = 5). Of 103 patients suffered varying degrees of gastrointestinal fistulae and intra-abdominal infections, there were 66 cases of pancreatic fistulae (64.1%), 49 cases of enteric fistulae (47.6%), 26 cases of colonic fistulae (25.2%), 14 cases of gastric or gastrointestinal anastomotic fistulae (13.6%), and 13 cases of biliary fistulae (12.6%). Ninety-five patients survived and eight patients died after therapy; the mean length of intensive care unit stay was 33 days. The number of patients who underwent emergency pancreaticoduodenectomy (EPD), the incidence of blood transfusion, the number of fistulae per patient, and the duration of mechanical ventilation and bacteremia in the mortality group were substantially higher than in the survival group (p < 0.05 each). The patients who underwent EPD had more grade 5 pancreatic injuries, more blood transfusions, higher peak total bilirubin, greater numbers of fistulae and open abdomen, and longer duration of mechanical ventilation and mortality than other patients (p < 0.05 each). Conclusions: The grade of pancreatic injury was associated with mortality and post-operative complications. The post-operative mortality and occurrence of complications of EPD because of abdominal trauma were significant; use of damage control surgery could potentially reduce the morbidity and mortality related to this procedure.

Abstract
Background: Pseudomonas aeruginosa is isolated at variable rates from intra-abdominal infections (IAI). Not all recommended empiric regimens for IAI include anti-Pseudomonas aeruginosa activity, for example, ceftriaxone and metronidazole. We hypothesized that within an adult population, Pseudomonas aeruginosa is a relatively rare isolate and has no association with mortality, and thus, empiric therapy with anti-Pseudomonas aeruginosa activity is not warranted. Patients and Methods: All IAI with positive cultures treated between 1997 and 2017 at a single institution were analyzed. This data set was divided into two cohorts, namely, those with cultures positive for Pseudomonas aeruginosa and those without. Demographics and in-hospital mortality were compared by Student t-test and χ2 analysis. Predictors of isolation of Pseudomonas aeruginosa and in-hospital mortality were done by logistic regression (LR) analysis. Results: In total, 2,420 IAIs were identified, 104 (4.3%) with Pseudomonas aeruginosa and 2,316 (95.7%) without. Major demographic differences between patients with Pseudomonas aeruginosa and those without included a higher rate of health-care-associated infections (87/104, 83.7% vs. 621/2316, 26.8%; p = 0.02), a higher rate of intensive care unit (ICU)-acquired infections (23/104, 22.1% vs. 329/2316, 14.2%; p = 0.04) and a higher Acute Physiology and Chronic Health Evaluation (APACHE) II score (17.7 ± 0.8 vs. 14.5 ± 0.2; p < 0.0001). There was an increased rate of Pseudomonas aeruginosa isolation with increasing APACHE II score. Independent predictors of isolation of Pseudomonas aeruginosa by LR included APACHE II score and days of hospitalization prior to diagnosis. Crude in-hospital mortality was similar between groups: Pseudomonas aeruginosa 14/104 (13.5%) and 276/2316 (11.9%), p = 0.79. After controlling for age, gender, APACHE II, prior transfusion, immunosuppression status, solid organ transplant status, healthcare-association, and days of hospitalization prior to diagnosis, the isolation of Pseudomonas aeruginosa was not associated with mortality. Conclusion: Pseudomonas aeruginosa is infrequently isolated and overall not associated with mortality. Nonetheless, there may be a population that merits empiric anti-Pseudomonas aeruginosa therapy: those with APACHE II ≥20 or a significant length of hospitalization prior to diagnosis.

Abstract
BACKGROUND The spleen is an important contributor to the uncontrolled, excessive release of proinflammatory signals during sepsis that leads to the development of tissue injury and diffuse end-organ dysfunction. Therapeutic pulsed ultrasound (pUS) has been shown to inhibit splenic leukocyte release and reduce cytokine production in other inflammatory disease processes. We hypothesized that pUS treatment inhibits spleen-derived inflammatory responses and increases survival duration in rats with severe intra-abdominal sepsis leading to septic shock. MATERIALS AND METHODS Rats with intra-abdominal sepsis, induced by cecal ligation and incision, underwent abdominal washout, intra-peritoneal administration of cefazolin, and then either no further treatment (control), splenectomy, or pUS of the spleen. Animals were observed for the primary endpoint of survival duration. RESULTS Survival curves were significantly different for all groups (P < 0.01). Median survival increased from 9.5 h in control rats to 19.8 h in pUS rats and 35.0 h in splenectomy rats (P < 0.01). At 4 h after cecal ligation and incision, the pUS group had decreased splenic contraction and leukocyte count (P = 0.03) compared with control, indicating reduced exodus of splenic leukocytes. In addition, elevation in plasma TNF-α and MCP-1 was significantly attenuated in the pUS group (P < 0.05 versus control). Splenic β2 adrenergic receptor levels and phosphorylated Akt were significantly more elevated in the pUS group (P < 0.01 versus control). CONCLUSIONS pUS significantly prolonged the survival duration of rats with severe intra-abdominal sepsis. This treatment may be an effective, noninvasive therapy that dampens detrimental immune responses during septic shock by activating β2 adrenergic receptor-Akt phosphorylation in the cholinergic anti-inflammatory pathway.

Abstract
OBJECTIVES Coagulopathy of coronavirus disease 2019 is largely described as hypercoagulability, yet both thrombotic and hemorrhagic complications occur. Although therapeutic and prophylactic anticoagulant interventions have been recommended, empiric use of antifactor medications (heparin/enoxaparin) may result in hemorrhagic complications, including death. Furthermore, traditional (antifactor) anticoagulation does not address the impact of overactive platelets in coronavirus disease 2019. The primary aim was to evaluate if algorithm-guided thromboelastography with platelet mapping could better characterize an individual's coronavirus disease 2019-relatedcoagulopathic state and, secondarily, improve outcomes. DESIGN SETTING AND PATIENTS Coronavirus disease 2019 patients (n = 100), receiving thromboelastography with platelet mapping assay upon admission to an 800-bed tertiary-care hospital, were followed prospectively by a hospital-based thromboelastography team. Treating clinicians were provided with the option of using a pre-established algorithm for anticoagulation, including follow-up thromboelastography with platelet mapping assays. Two groups evolved: 1) patients managed by thromboelastography with platelet mapping algorithm (algorithm-guided-thromboelastography); 2) those treated without thromboelastography with platelet mapping protocols (non-algorithm-guided). Outcomes included thrombotic/hemorrhagic complications, pulmonary failure, need for mechanical ventilation, acute kidney injury, dialysis requirement, and nonsurvival. INTERVENTIONS Standard-of-care therapy with or without algorithm-guided-thromboelastography support. MEASUREMENTS AND MAIN RESULTS Although d-dimer, C-reactive protein, and ferritin were elevated significantly in critically ill (nonsurvivors, acute kidney injury, pulmonary failure), they did not distinguish between coagulopathic and noncoagulopathic patients. Platelet hyperactivity (maximum amplitude-arachidonic acid/adenosine diphosphate > 50 min), with or without thrombocytosis, was associated with thrombotic/ischemic complications, whereas severe thrombocytopenia (platelet count < 100,000/μL) was uniformly fatal. Hemorrhagic complications were observed with decreased factor activity (reaction time > 8 min). Non-algorithm-guided patients had increased risk for subsequent mechanical ventilation (relative risk = 10.9; p < 0.0001), acute kidney injury (relative risk = 2.3; p = 0.0017), dialysis (relative risk = 7.8; p < 0.0001), and death (relative risk = 7.7; p < 0.0001), with 17 of 28 non-algorithm-guided patients (60.7%) dying versus four algorithm-guided-thromboelastography patients (5.6%) (p < 0.0001). Thromboelastography with platelet mapping-guided antiplatelet treatment decreased mortality 82% (p = 0.0002), whereas non-algorithm-guided (compared with algorithm-guided-thromboelastography) use of antifactor therapy (heparin/enoxaparin) resulted in 10.3-fold increased mortality risk (p = 0.0001). CONCLUSIONS Thromboelastography with platelet mapping better characterizes the spectrum of coronavirus disease 2019 coagulation-related abnormalities and may guide more tailored, patient-specific therapies in those infected with coronavirus disease 2019.

Abstract
Antimicrobial stewardship efforts that include surgeons rely on healthy and open communications between surgeons, infectious diseases specialists, and pharmacists. These efforts most frequently are related to surgical prophylaxis, the management of surgical infections, and surgical critical care. Policy should be based on best evidence and timely interactions to develop consensus on how to develop appropriate guidelines and protocols. Flexibility on all sides leads to increasingly strong relationships over time.

Abstract
BACKGROUND The long-term implications of tracheostomy in cardiac surgical patients are largely unknown. We sought to investigate outcomes including decannulation and long-term mortality in a population of post-cardiac surgery patients. METHODS All patients undergoing cardiac surgery at a single institution between 1997 and 2016 were evaluated for postoperative tracheostomy placement, time to decannulation, and mortality. Patients were stratified by tracheostomy placement, as well as by successful decannulation for comparison. Kaplan-Meier analysis identified time to decannulation and mortality and a Fine-Gray's competing risk regression, accounting for mortality, identified predictors of time to decannulation. RESULTS Of 14,600 total cardiac surgery patients, only 309 required tracheostomy. Patients with tracheostomy had high rates of perioperative comorbidities, including 60% with heart failure and 24% with postoperative stroke. Tracheostomy patients had high short-term and long-term mortality, with a median survival of 152 days, 1-year survival of 41%, and 5-year survival of 29.1%. Patients remained with tracheostomy in place for a median of 59 days, with a 1-year decannulation rate of 80% in living patients. Patients with older age (hazard ratio 0.98, P = .01), chronic lung disease (hazard ratio 0.66, P = .03), and preoperative or postoperative dialysis (hazard ratio 0.45, P < .01) were less likely to have their tracheostomy removed. CONCLUSIONS Tracheostomy is associated with poor long-term survival of cardiac surgery patients. However, patients who do survive have a short duration of tracheostomy with almost all surviving patients eventually decannulated. This finding provides valuable information for pre-procedural counseling for these high-risk patients and their families.

Abstract
Laparotomy has been the favored approach regarding surgical management of small bowel obstruction (SBO); however, laparoscopy may offer improved outcomes. Patients undergoing laparoscopic lysis of adhesions (LOA) at our institution for SBO will have lower postoperative morbidity and 30-day mortality. Patients undergoing LOA at our institution, from 2000 to 2011, were reviewed. Categorical data were analyzed with χ2or Fisher's exact tests. Continuous data were analyzed with Student's t test or Wilcoxon rank sum. One hundred two (38 laparoscopic, 64 open) LOA cases were selected. Perioperative contamination and conservative management were higher in the open group. Open cases had a greater incidence of intensive care unit (ICU) admissions and longer length of stay. Stratified analysis determined a strong association between perioperative contamination and a higher incidence of ICU admission, perioperative contamination and longer LOS, and conservative management and longer LOS. Finally, patient outcome did not differ between those treated by surgeons trained in minimally invasive surgery (MIS) compared with those not trained in MIS. Careful consideration of surgical approach and timing is called for in all patients with SBO; however, whenever possible, laparoscopic preference should be given to most patients in an expeditious fashion irrespective of MIS training.

Abstract
Elderly patients are at high risk for mortality after injury. We hypothesized that trauma benchmarking efforts would benefit from development of a geriatric-specific model for risk-adjusted analyses of trauma center outcomes. A total of 57,973 records of elderly patients (age older than 65 years), which met our selection criteria, were submitted to the National Trauma Database and included within the National Sample Project between 2003 and 2006. These cases were used to construct a multivariable logistic regression model, which was compared with the American College of Surgeons Committee on Trauma's Trauma Quality Improvement Project's (TQIP) existing model. Additional spline regression analyses were performed to further objectively quantify the physiologic differences between geriatric patients and their younger counterparts. The geriatric-specific and TQIP mortality models shared several covariates: age, Injury Severity Score, motor component of the Glasgow Coma Scale, and systolic blood pressure. Our model additionally used temperature and the presence of mechanical ventilation. Our geriatric-specific regression mode generated a superior c-statistic as compared with the TQIP approximation (0.85 vs 0.77; P = 0.048). Spline analyses demonstrated that elderly patients appear to be less likely to tolerate relative hypotension with higher observed mortality at initial systolic blood pressures of 90 to 130 mmHg. Although the TQIP model includes a single age component, these data suggest that each variable needs to be adjusted for age to more accurately predict mortality in the elderly. Clearly, a separate geriatric model for predicting outcomes is not only warranted, but necessary.

Abstract
Background: Surgical site infection (SSI) surveillance programs are strongly recommended as a core component of effective national infection prevention and control (IPC) programs. Participation in national SSI surveillance (nSSIS) programs has been shown to decrease reported SSIs among high-income countries (HICs), and it is expected that the same is possible among low- and middle-income countries (LMICs). We sought to determine what, if any nSSIS programs exist among LMICs. Methods: A cross-sectional survey was performed to evaluate existence of nSSIS of World Bank-defined LMICs. A digital survey assessment for presence of national IPC and nSSIS programs was delivered to persons capable of identifying the presence of such a program. Statistical analysis was performed using STATA. Institutional Review Board approval was obtained for this study. Results: Of the 137 countries identified, 55 (40%) were upper middle income (UMI), 47 (34%) were lower middle income (LMI), and 34 (25%) were low income. Representatives from 39 (28%) LMICs completed the survey. Of these respondent countries, 13 (33%) reported the presence of a national IPC program. There was no difference between countries with IPC programs and those without with respect to country income designation, population size, World Health Organization region, or conflict status. Only five (13% of all respondents) reported presence of a nSSIS program. Conclusions: National surgical site infection surveillance programs are an integral component of a country's ability to provide safe surgical procedures. Presence of nSSIS was reported infrequently in LMICs. International governing bodies should be encouraged to guide LMIC leadership in establishing a nSSIS infrastructure that will help enable safe surgical procedures.

Abstract
Background: Fever is a common response to both infectious and non-infectious physiologic insults in the critically ill, and in certain populations it appears to be protective. Fever is particularly common in trauma patients, and even more so in those with infections. The relationship between fever, trauma status, and mortality in patients with an infection is unclear. Patients and Methods: A review of a prospectively maintained institutional database over a 17-year period was performed. Surgical and trauma intensive care unit (ICU) patients with a nosocomial infection were extracted to compare in-hospital mortality among trauma and non-trauma patients with and without fever. Univariable analyses compared patient and infection characteristics between trauma and non-trauma patients. A multivariable logistic regression model was created to identify predictors of in-hospital mortality, with a focus on fever and trauma status. Results: Nine hundred forty-one trauma patients and 1,449 non-trauma patients with ICU-acquired infections were identified. Trauma patients were younger (48 vs. 59, p < 0.001), more likely to be male (73% vs. 56%, p < 0.001), more likely to require blood transfusion (74% vs. 47%, p < 0.001), had lower Acute Physiology and Chronic Health Evaluation (APACHE) II scores (18 vs. 19, p = 0.02), and had lower rates of comorbidities. Trauma patients were more likely to develop a fever (72% vs. 43%, p < 0.001) and had lower in-hospital mortality (9.6% vs. 22.6%, p < 0.001). In multivariable analysis, non-trauma patients with fever had a lower odds of mortality compared with non-trauma patients without fever (odds ratio [OR] 0.63, p = 0.004). Trauma patients with fever had the lowest odds ratio for mortality when compared to non-trauma patients without fever (OR 0.25, p < 0.001). Conclusions: In this large cohort of trauma and surgical ICU patients with ICU-acquired infections, fever was associated with a lower odds of mortality in both trauma and non-trauma patients. Further investigation is needed to determine the mechanisms behind the interplay between trauma status, fever, and mortality.

Abstract
Optimal energy goals for adult, obese critically ill surgical patients are unclear. To date, there has been little data comparing feeding regimens for obese and non-obese critically ill surgical patients and the effect on outcomes. The objective was to compare the effect of hypoenergetic and euenergetic feeding goals in critically ill obese patients on outcomes, including infection, intensive care unit length of stay, and mortality. We hypothesized that hypoenergetic feeding of patients with premorbid obesity (body mass index ≥ 30 kg•m-2) during critical illness does not affect clinical outcomes. Post hoc analyses were performed on critically ill surgical patients enrolled in a randomized controlled trial. Patients were randomized to receive 25-30 kcal•kg-1•d-1 (105-126 kJ.kg-1•d-1, euenergetic) or 12.5-15 kcal•kg-1•d-1 (52-63 kJ.kg-1 •d-1, hypoenergetic), with equal protein allocation (1.5 g•kg-1•d-1). The effect of feeding regimen on outcomes in obese and nonobese patients were assessed. Of the 83 patients, 30 (36.1%) were obese (body mass index ≥ 30 kg•m-2). Average energy intake differed based on feeding regimen (hypoenergetic: 982±61 vs euenergetic: 1338±92 kcal•d-1, P = .02). Comparing obese and nonobese patients, there was no difference in the percentage acquiring an infection (66.7% [20/30] vs 77.4% [41/53], P = .29), intensive care unit length of stay (16.4±3.7 vs 14.3±0.9 days, P = .39), or mortality (10% [3/30] vs 7.6% [4/53], P = .7). Within the subset of obese patients, the percentage acquiring an infection (hypoenergetic: 78.9% [15/19] vs euenergetic: 45.5% [5/11], P = .11) was not affected by the feeding regimen. Within the subset of nonobese patients, there was a trend toward more infections in the euenergetic group (hypoenergetic: 63.6% [14/22] vs euenergetic: 87.1% [27/31], P = .05). Hypoenergetic feeding does not appear to affect clinical outcomes positively or negatively in critically ill patients with premorbid obesity.

Abstract
BACKGROUND A subset of patients who undergo cardiac surgery require percutaneous endoscopic gastrostomy (PEG) tube for enteral access to receive nutritional support. There are limited data evaluating the outcomes of these patients and the duration of nutritional support required. METHODS All cardiac surgery patients (1994 to 2017) were stratified by postoperative PEG requirement. Patients were excluded if they required preoperative nutritional support, began nutritional support more than 30 days postoperatively, or if the PEG was placed more than 90 days after the index cardiac operation. Kaplan-Meier survival analysis was used to estimate overall survival and time to PEG removal. A Fine-Gray competing risk model was constructed to determine factors impacting PEG removal. RESULTS A total of 16,727 cardiac surgery patients were included, with 310 (1.9%) requiring PEG. The median time to PEG placement was 14.5 (interquartile range, 10 to 22) days with 1 (0.3%) PEG procedural mortality. One-year survival was 50.4% vs 91.8% in the general cardiac surgery population. A total of 113 patients had their PEG removed at a median of 255 days. Of living PEG patients at 1 year, 52.1% had their PEG removed. Factors that were associated with PEG removal were age (hazard ratio [HR], 0.98; P = .03), ejection fraction (HR, 1.03; P < .01), and renal failure (HR, 0.50; P < .01). CONCLUSIONS Patients who require PEG after cardiac surgery are a high-risk cohort. However, those who survive their acute illness often recover to a point where nutrition can be maintained without a feeding tube. These data provide meaningful information for counseling patients and their families that are considering PEG after cardiac surgery.

Abstract
Background: Surgical site infection (SSI) continues to be a common and costly complication after surgery. The current commonly used definitions of SSI were devised more than two decades ago and do not take in to account more modern technology that could be used to make diagnosis more consistent and precise. Patient-generated health data (PGHD), including digital imaging, may be able to fulfill this objective. Methods: The published literature was examined to determine the current state of development in terms of using digital imaging as an aide to diagnose SSI. This information was used to devise possible methodology that could be used to integrate digital images to more objectively define SSI, as well as using these data for both surveillance activities and clinical management. Results: Digital imaging is a highly promising means to help define and diagnose SSI, particularly in remote settings. Multiple groups continue to actively study these emerging technologies, however, present methods remain based generally on subjective rather than objective observations. Although current images may be useful on a case-by-case basis, similar to physical examination information, integrating imaging in the definition of SSI to allow more automated diagnosis in the future will require complex image analysis combined with other available quantified data. Conclusions: Digital imaging technology, once adequately evolved, should become a cornerstone of the criteria for both the clinical and surveillance definitions of SSI.

Abstract
Background: Infections caused by Staphylococcus aureus continue to plague surgical patients, whether as surgical site infections or other nosocomial infections that complicate surgical care. The only meaningful methods available to decrease the risk of developing such infections are topical skin antisepsis (pre-operative skin preparation) and peri-operative antibiotic prophylaxis, neither of which offer a panacea. Alternatives to the latter are sought so as to minimize antibiotic selection pressure as a factor in the increasing problem of antimicrobial drug resistance. This review considers the possibility that immunization against S. aureus may offer a viable alternative for prophylaxis. Methods: Review and synthesis of pertinent English-language medical literature. Results: Vaccination against viral pathogens has been in successful clinical use for more than two centuries and was instrumental in the eradication of smallpox and the near-elimination of diseases such as poliomyelitis. Vaccinations against a limited number of bacterial pathogens (e.g., Bordetella pertussis, Clostridium tetanii, Corynebacterium diphtheriae, Haemophilus influenzae type b, Neisseria meningiditis, Streptococcus pneumoniae) have also been introduced with success, whereas others against bacteria are in development (C. difficile, Pseudomonas aeruginosa, S. aureus). Vaccination against S. aureus infection is in current veterinary use (e.g., to prevent mastitis among dairy cattle) but has not been successful to date in human beings despite multiple attempts, although development continues. Conclusions: Because of its complex microbiology, including multiple virulence factors and the ability to evade host immune surveillance, S. aureus presents numerous antigenic targets for vaccine development. Failure of two prior single-antigen vaccines in clinical trials has led to the consensus that future vaccine candidates must be directed against multiple antigens. Two distinct four-antigen vaccines are in clinical trials, but efficacy is yet to be determined.

Abstract
The appropriate duration of surgical antibiotic prophylaxis in orthotopic liver transplantation (OLT) in the presence of significant iatrogenic immunosuppression is unclear. We hypothesized that 72 hours of perioperative antibiotic prophylaxis would decrease rates of surgical site infection (SSI) in OLT patients when compared with intraoperative antibiotic prophylaxis alone. OLT recipients were randomized to receive either intraoperative antibiotics only (short antibiotics [SAs]) or 72 hours of perioperative antibiotics (extended antibiotics [EAs]). A total of 102 patients were randomized: 51 to the EA group and 51 to the SA group. Rates of SSI and nosocomial infection (NI) in the SA group were 19% and 17%, respectively, compared with 27% (SSI; P = 0.36) and 22% (NI; P = 0.47) in the EA group, although these differences were not statistically significant. Intensive care unit (ICU) length of stay (LOS), hospital LOS, 30-day mortality, and time to infection were also similar between the 2 groups. Patients developing infections had longer ICU LOS and hospital LOS and a higher association with reoperation, endoscopic retrograde cholangiopancreatography, and 30-day readmission. In conclusion, extending perioperative antibiotics to 72 hours from intraoperative dosing alone in OLT patients does not appear to decrease the incidence of SSI or NI. The results from this pilot trial with 60% power suggest that it is acceptable for OLT recipients to receive intraoperative antibiotic prophylaxis alone.

Abstract
Stimulator of interferons genes (STING) is an adaptor protein that plays a critical role in the secretion of type I interferons and pro-inflammatory cytokines in response to cytosolic nucleic acid. Recent research indicates the involvement of the STING pathway in uncontrolled inflammation, sepsis, and shock. STING signaling is significantly up-regulated in human sepsis, and STING agonists are suggested to contribute to the pathogenesis of sepsis and shock. Nevertheless, little is known about the consequences of activated STING-mediated signaling during sepsis. It has been shown that aberrant activation of the STING-dependent way can result in increased inflammation, type I interferons responses, and cell death (including apoptosis, necroptosis, and pyroptosis). In addition, autophagy modulation has been demonstrated to protect against multiple organs injuries in animal sepsis model. However, impaired autophagy may contribute to the aberrant activation of STING signaling, leading to uncontrolled inflammation and cell death. Here we present a comprehensive review of recent advances in the understanding of STING signaling, focusing on the regulatory mechanisms and the roles of this pathway in sepsis.

Abstract
BACKGROUND The Sequential Organ Failure Assessment (SOFA) and quick SOFA (qSOFA) scores replaced the Systemic Inflammatory Response System (SIRS) criteria for defining sepsis, and are often utilized to identify infection, however remain understudied in surgical populations. METHODS Daily SOFA, qSOFA, and SIRS scores were prospectively collected in a surgical/trauma intensive care unit (ICU), comparing scores between patients with and without new infection. Multivariable analysis controlled for ICU type and pre-existing infection. RESULTS Scores were recorded for 1942 patient-days, including 1385 (71%) with no infection, 439 (23%) with existing/treated infection, and 120 (6.2%) with new infection. Scores were globally elevated, with 98% having SOFA score ≥2, 82% with qSOFA score ≥2, and 92% meeting ≥2 SIRS criteria. Neither univariate nor multivariate analysis revealed a correlation between SOFA, qSOFA, or SIRS score and infection. CONCLUSION No scores correlated with new infection, potentially related to increased existing inflammation in this population. SUMMARY The Sequential Organ Failure Assessment (SOFA) and quick SOFA (qSOFA) have replaced the Systemic Inflammatory Response System (SIRS) criteria for sepsis, however are not well investigated in surgical populations or for identifying infections, as they are often used in practice. In this study, neither daily SOFA, qSOFA, nor SIRS criteria correlated with new infection in a population of critically ill surgical patients. Scores were globally elevated in non-infected patients, potentially related to high levels of existing inflammation in this population.

Abstract
Despite evidence supporting the effectiveness of best practices of infection prevention and management, many surgeons worldwide fail to implement them. Evidence-based practices tend to be underused in routine practice. Surgeons with knowledge in surgical infections should provide feedback to prescribers and integrate best practices among surgeons and implement changes within their team. Identifying a local opinion leader to serve as a champion within the surgical department may be important. The “surgeon champion” can integrate best clinical practices of infection prevention and management, drive behavior change in their colleagues, and interact with both infection control teams in promoting antimicrobial stewardship.

Abstract
BACKGROUND Recent anti-microbial exposure has been associated with poor outcomes after infection in a mixed population. We hypothesized that recent anti-microbial exposure would be associated with poor outcomes of elective surgery. METHODS From August 2015 to August 2016, all elective surgical patients were questioned prospectively about anti-microbial exposure during the prior three months. Multivariable models were used to calculate risk-adjusted odds ratios for anti-microbial exposure controlling for surgeon influence. Primary outcomes were any serious complication, any complication, any infection, and surgical site infection. Secondary outcomes were length of stay, C. difficile infection, and death. A separate analysis of patients excluding those having colorectal surgery who had undergone an oral antibiotic bowel preparation also was performed. RESULTS Ninety-four percent of eligible patients (n = 1,538) answered the exposure question, with a three-month anti-microbial exposure rate of 34.1%. Colorectal surgery patients had the highest exposure rate, whereas hernia patients had the lowest. Exposed patients had higher rates of any complication, any infection, and surgical site infection, as well as a median two-day longer hospital stay. There were no differences in C. difficile infection or death between the groups. After risk adjustment, anti-microbial exposure was independently associated with any serious complication for all patients as well as with complications and infection in patients having an operation other than colorectal surgery. CONCLUSION Recent anti-microbial exposure is associated with more complications of elective surgery. Anti-microbial drug-induced alterations in microbiome-related inflammatory responses may play a role, highlighting an opportunity for pre-surgical intervention in this at-risk population.

Abstract
BACKGROUND Surgical site infections (SSIs) are among the most common complications after definitive treatment for intestinal fistulae. Serum inflammatory markers including white blood cell count (WBC), C-reactive protein (CRP), interleukin-6 (IL-6), as well as procalcitonin (PCT) have been used to help diagnosis post-operative complications. OBJECTIVE The goal of this study was to assess the clinical value of inflammatory markers, specifically IL-6, in predicting SSIs after intestinal fistulae resection. METHODS A total of 184 consecutive patients who underwent elective intestinal fistula resection were enrolled prospectively. All patients were screened to exclude patients with existing clinical infection. Plasma IL-6 concentrations, serum PCT, and CRP concentrations were measured pre-operatively and on post-operative days one, three, and seven. The predictive value of each laboratory marker for SSI was calculated. RESULTS The incidence of SSI after elective intestinal fistula resection was 26.7%. Interleukin-6, PCT, and CRP concentrations were higher in patients with SSIs compared with patients without. In contrast, there was no statistical difference for WBC counts between the two groups. Receiver operating characteristic curves demonstrated that IL-6 had the highest diagnostic effectiveness for post-operative SSI on post-operative day one, with an area under the curve of 0.77, and a sensitivity of 85.7% and specificity of 63.9%. CONCLUSION A concentration of IL-6 above 95.6 ng/L on post-operative day one and 52.5 ng/L on post-operative day three, and a concentration of PCT exceeding 0.61 mcg/L predict the occurrence of SSI after definitive operations for gastrointestinal fistulae.

Abstract
BACKGROUND Critically ill surgical patients often receive inadequate enteral nutrition using traditional rate-based feeding methods. An alternative strategy is volume-based feeding, in which feeding rates are adjusted to deliver a goal volume per day. METHODS This prospective quality improvement study in a single surgical, trauma, and burn ICU compared volume-based feeding to rate-based feeding in a before-and-after design. Outcomes included calories and protein delivered, length of stay, infection, and mortality. RESULTS A total of 50 patients received volume-based feeding and 49 rate-based feeding. The volume-based group received a higher proportion of goal calories (84.5% vs. 73.4%; p = 0.005) and protein (86.2% vs. 77.4%; p = 0.01), as well as increased total daily calories (1604 vs. 1356 kcal; p = 0.02). There was no difference in length of stay, mortality, aspiration, or gastrointestinal intolerance. CONCLUSIONS Volume-based feeding improved nutritional intake in critically ill surgical patients, although this study was underpowered to determine differences in clinical outcomes.
