RESUMO
Severe infection and sepsis are medical emergencies. High morbidity and mortality are linked to CNS dysfunction, excessive inflammation, immune compromise, coagulopathy and multiple organ dysfunction. Males appear to have a higher risk of mortality than females. Currently, there are few or no effective drug therapies to protect the brain, maintain the blood brain barrier, resolve excessive inflammation and reduce secondary injury in other vital organs. We propose a major reason for lack of progress is a consequence of the treat-as-you-go, single-nodal target approach, rather than a more integrated, systems-based approach. A new revolution is required to better understand how the body responds to an infection, identify new markers to detect its progression and discover new system-acting drugs to treat it. In this review, we present a brief history of sepsis followed by its pathophysiology from a systems' perspective and future opportunities. We argue that targeting the body's early immune-driven CNS-response may improve patient outcomes. If the barrage of PAMPs and DAMPs can be reduced early, we propose the multiple CNS-organ circuits (or axes) will be preserved and secondary injury will be reduced. We have been developing a systems-based, small-volume, fluid therapy comprising adenosine, lidocaine and magnesium (ALM) to treat sepsis and endotoxemia. Our early studies indicate that ALM therapy shifts the CNS from sympathetic to parasympathetic dominance, maintains cardiovascular-endothelial glycocalyx coupling, reduces inflammation, corrects coagulopathy, and maintains tissue O2 supply. Future research will investigate the potential translation to humans.

INTRODUCTION: Postoperative (postop) management of pediatric perforated appendicitis varies significantly, and postop intra-abdominal abscesses (IAA) remain a significant issue. Between 2019 and 2020, our standardized protocol included routine postop labs after an appendectomy for perforated appendicitis. However, given the lack of predictive utility of these routine labs, we discontinued this practice in 2021. We hypothesize that discontinuing routine postop labs will not be associated with an increase in complication rates after an appendectomy for pediatric perforated appendicitis. METHODS: A single-institution, retrospective review of all pediatric appendectomies for perforated appendicitis from January 2019 to December 2021 was conducted at University Hospitals Rainbow Babies and Children's Hospital in Cleveland, Ohio. Data were collected on rate of complications (IAA development, re-admissions, bowel obstructions, superficial surgical site infections, intensive care unit transfers, Clostridium difficile infections, allergic reactions, and transfusions), postop imaging, postop interventions, and length of stay. Statistical analysis was completed using Fisher's exact test and Mann-Whitney U-test. RESULTS: A total of 109 patients (2019-2020 n = 61, 2021 n = 48) were included in the study. All 61 patients from 2019 to 2020 had postop labs compared to only eight patients in 2021. There was no statistically significant difference between the two groups in overall complication rates, but there was a decrease in IAAs reported in 2021 (P = 0.03). There were no statistically significant differences in other complications, postop imaging usage, or postop interventions. The median length of stay was 4.5 d in 2021 compared to 6.0 d in 2019-2020 (P = 0.009). CONCLUSIONS: Discontinuing routine postop labs is not associated with an increase in overall complications rates. Further studies are needed to determine whether routine postop labs can be safely removed in pediatric patients with perforated appendicitis, which would reduce patient discomfort and care costs.

INTRODUCTION: One of the significant complications of operative liver trauma is intra-abdominal abscesses (IAA). The objective of this study was to determine risk factors associated with postoperative IAA in surgical patients with major operative liver trauma. METHODS: A retrospective multi-institutional study was performed at 13 Level 1 and Level 2 trauma centers from 2012 to 2021. Adult patients with major liver trauma (grade 3 and higher) requiring operative management were enrolled. Univariate and multivariate analyses were performed. RESULTS: Three hundred seventy-two patients were included with 21.2% (n = 79/372) developing an IAA. No difference was found for age, gender, injury severity score, liver injury grade, and liver resections in patients between the groups (P > 0.05). Penetrating mechanism of injury (odds ratio (OR) 3.42, 95% confidence interval (CI) 1.54-7.57, P = 0.02), intraoperative massive transfusion protocol (OR 2.43, 95% CI 1.23-4.79, P = 0.01), biloma/bile leak (OR 2.14, 95% CI 1.01-4.53, P = 0.04), hospital length of stay (OR 1.04, 95% CI 1.02-1.06, P < 0.001), and additional intra-abdominal injuries (OR 2.27, 95% CI 1.09-4.72, P = 0.03) were independent risk factors for IAA. Intra-abdominal drains, damage control laparotomy, total units of packed red blood cells, number of days with an open abdomen, total abdominal surgeries, and blood loss during surgery were not found to be associated with a higher risk of IAA. CONCLUSIONS: Patients with penetrating trauma, massive transfusion protocol activation, longer hospital length of stay, and injuries to other intra-abdominal organs were at higher risk for the development of an IAA following operative liver trauma. Results from this study could help to refine existing guidelines for managing complex operative traumatic liver injuries.

INTRODUCTION: A dysregulated immune system is a major driver of the mortality and long-term morbidity from sepsis. With respect to macrophages, it has been shown that phenotypic changes are critical to effector function in response to acute infections, including intra-abdominal sepsis. Invariant natural killer T cells (iNKT cells) have emerged as potential central regulators of the immune response to a variety of infectious insults. Specifically, various iNKT cell:macrophage interactions have been noted across a spectrum of diseases, including acute events such as sepsis. However, the potential for iNKT cells to affect peritoneal macrophages during an abdominal septic event is as yet unknown. METHODS: Cecal ligation and puncture (CLP) was performed in both wild type (WT) and invariant natural killer T cell knockout (iNKT-/-) mice. 24 h following CLP or sham operation, peritoneal macrophages were collected for analysis. Analysis of macrophage phenotype and function was undertaken to include analysis of bactericidal activity and cytokine or superoxide production. RESULTS: Within iNKT-/- mice, a greater degree of intraperitoneal macrophages in response to the sepsis was noted. Compared to WT mice, within iNKT-/- mice, CLP did induce an increase in CD86+ and CD206+, but no difference in CD11b+. Unlike WT mice, intra-abdominal sepsis within iNKT-/- mice induced an increase in Ly6C-int (5.2% versus 14.9%; P < 0.05) and a decrease in Ly6C-high on peritoneal macrophages. Unlike phagocytosis, iNKT cells did not affect macrophage bactericidal activity. Although iNKT cells did not affect interleukin-6 production, iNKT cells did affect IL-10 production and both nitrite and superoxide production from peritoneal macrophages. CONCLUSIONS: The observations indicate that iNKT cells affect specific phenotypic and functional aspects of peritoneal macrophages during polymicrobial sepsis. Given that pharmacologic agents that affect iNKT cell functioning are currently in clinical trial, these findings may have the potential for translation to critically ill surgical patients with abdominal sepsis.

BACKGROUND: Peritoneal metastasis of gastric cancer is closely associated with dismal prognosis. In previous preclinical proof-of-concept studies, an amido-bridged nucleic acid (AmNA)-modified antisense oligonucleotide (ASO), designated ASO-4733 that targets the gene encoding synaptotagmin XIII (SYT13), inhibited cellular functions required for the formation of peritoneal metastasis of gastric cancer cells. ASO-4733 achieved therapeutic effects when intra-abdominally administered to mouse xenograft models. Here, we conducted an analysis of Syt13-deficient mice to determine the pharmacokinetics and toxicity of intra-abdominal administration of ASO-4733. METHODS: The effects of Syt13-deficiency in mice were determined. Good Laboratory Practice toxicity tests and the toxicokinetics of intra-abdominal administration of ASO-4733 were conducted in cynomolgus monkeys and rats. The pharmacokinetics of ASO-4733 administered intravenously or intra-abdominally to rats were investigated. RESULTS: Syt13-deficient mice exhibited normal reproduction, organ functions, and motor functions. Weekly intra-abdominal administration of ASO-4733 (125 mg/kg), corresponding to a 50-fold increase of the estimated clinical dose for 4 weeks, was well tolerated by cynomolgus monkeys. In rats, off-target toxicity (not attributable to hybridization) was observed after weekly intra-abdominal administration of ASO-4733. Blood concentrations of ASO-4733 were lower and rose more slowly after intra-abdominal administration compared with intravenous administration. CONCLUSIONS: The preclinical profile of intra-abdominal administration of ASO-4733 demonstrated its suitability for entry into clinical trials of patients with peritoneal metastasis of gastric cancer.
RESUMO
BACKGROUND: Metagenomic next-generation sequencing (mNGS) has been increasingly applied in sepsis. We aimed to evaluate the diagnostic and therapeutic utility of mNGS of paired plasma and peritoneal drainage (PD) fluid samples in comparison to culture-based microbiological tests (CMTs) among critically ill patients with suspected acute intra-abdominal infections (IAIs). METHODS: We conducted a prospective study from October 2021 to December 2022 enrolling septic patients with suspected IAIs (n = 111). Pairwise CMTs and mNGS of plasma and PD fluid were sent for pathogen detection. The mNGS group underwent therapeutic regimen adjustment based on mNGS results for better treatment. The microbial community structure, clinical features, antibiotic use and prognoses of the patients were analyzed. RESULTS: Higher positivity rates were observed with mNGS versus CMTs for both PD fluid (90.0% vs. 48.3%, p < 0.005) and plasma (76.7% vs. 1.6%, p < 0.005). 90% of enrolled patients had clues of suspected pathogens combining mNGS and CMT methods. Gram-negative pathogens consist of most intra-abdominal pathogens, including a great variety of anaerobes represented by Bacteroides and Clostridium. Patients with matched plasma- and PD-mNGS results had higher mortality and sepsis severity. Reduced usage of carbapenem (30.0% vs. 49.4%, p < 0.05) and duration of anti-MRSA treatment (5.1 ± 3.3 vs. 7.0 ± 8.4 days, p < 0.05) was shown in the mNGS group in our study. CONCLUSIONS: Pairwise plasma and PD fluid mNGS improves microbiological diagnosis compared to CMTs for acute IAI. Combining plasma and PD mNGS could predict poor prognosis. mNGS may enable optimize empirical antibiotic use.

PURPOSE OF REVIEW: The management of patients with Crohn's disease (CD) undergoing surgery is complex and optimization of modifiable factors perioperatively can improve outcomes. This review focuses on the perioperative management of CD patients undergoing surgery, emphasizing the need for a multi-disciplinary approach. RECENT FINDINGS: Research highlights the benefits of a comprehensive strategy, involving nutritional optimization, psychological assessment, and addressing septic complications before surgery. Despite many CD patients being on immune-suppressing medications, studies indicate that most of these medications are safe to use and should not delay surgery. However, a personalized approach for each case is needed. This review underscores the importance of multi-disciplinary team led peri-operative management of CD patients. We suggest that this can be done at a dedicated perioperative clinic for prehabilitation, with the potential to enhance outcomes for CD patients undergoing surgery.

AIM: There is ongoing controversy regarding the extent to which Hartmann's procedure (HP) should be used in rectal cancer treatment. This study was designed to investigate 30-day postoperative morbidity and mortality following HP, anterior resection (AR) and abdominoperineal resection (APR) for rectal cancer using a national registry. METHODS: All patients operated for rectal cancer, tumour height 5-15 cm, between the years 2010 and 2017, were identified through the Swedish colorectal cancer registry. RESULTS: A total of 8476 patients were included: 1210 (14%) undergoing HP, 5406 (64%) AR and 1860 (22%) APR. HP was associated with an increased risk of intra-abdominal infection (OR 1.7, CI 1.26-2.28, P = 0.0004) compared to AR and APR, while APR was related to an increased risk of overall complications (OR 1.18, CI 1.01-1.40, P = 0.040). No significant difference was observed in the rate of reoperations and readmissions between HP, AR and APR, and type of surgical procedure was not a risk factor for 30-day mortality. Findings from a subgroup analysis of patients with a tumour 5-7 cm from the anal verge revealed that HP was not associated with increased risk for complications or 30-day mortality. CONCLUSIONS: For patients where AR is not appropriate HP is a valid alternative with a favourable outcome. APR was associated with the highest overall 30-day complication rate.

INTRODUCTION: The advancement of seat belts have been essential to reducing morbidity and mortality related to motor vehicle collisions (MVCs). The "seat belt sign" (SBS) is an important physical exam finding that has guided management for decades. This study, comprising a systematic review and random-effects meta-analysis, asses the current literature for the likelihood of the SBS relating to intra-abdominal injury and surgical intervention. METHODS: PubMed and Scopus databases were searched from their beginnings through August 4, 2023 for eligible studies. Outcomes included the prevalence of intra-abdominal injury and need for surgical intervention. Cochrane's Risk of Bias (RoB) tool and the Newcastle-Ottawa Scale (NOS) were applied to assess risk of bias and study quality; Q-statistics and I2 values were used to assess for heterogeneity. RESULTS: The search yielded nine observational studies involving 3050 patients, 1937 (63.5%) of which had a positive SBS. The pooled prevalence of any intra-abdominal injury was 0.42, (95% CI 0.28-0.58, I2 = 96%) The presence of a SBS was significantly associated with increased odds of intra-abdominal injury (OR 3.62, 95% CI 1.12-11.6, P = 0.03; I2 = 89%), and an increased likelihood of surgical intervention (OR 7.34, 95% CI 2.03-26.54, P < 0.001; I2 = 29%). The measurement for any intra-abdominal injury was associated with high heterogeneity, I2 = 89%. CONCLUSION: This meta-analysis suggests that the presence of a SBS was associated with a statistically significant higher likelihood of intra-abdominal injury and need for surgical intervention. The study had high heterogeneity, likely due to the technological advancements over the course of this study, including seat belt design and diagnostic imaging sensitivity. Further studies with more recent data are needed to confirm these results.

BACKGROUND: Few studies have explored the impact of preoperative frailty on infectious complications in patients with a diagnosis of colorectal cancer (CRC). Therefore, this study aimed to investigate the effect of preoperative frailty on postoperative infectious complications and prognosis in patients with CRC using propensity score matching (PSM). METHODS: This prospective single-centre observational cohort study included 245 patients who underwent CRC surgery at the Department of Gastrointestinal Surgery, The Affiliated Lianyungang Hospital of Xuzhou Medical University between August 2021 to May 2023. Patients were categorised into two groups: frail and non-frail. They were matched for confounders and 1:1 closest matching was performed using PSM. Rates of infectious complications, intensive care unit (ICU) admission, 30-day mortality, and 90-day mortality, as well as postoperative length of hospital stay, total length of hospital stay, and hospital costs, were compared between the two groups. Binary logistic regression using data following PSM to explore independent factors for relevant outcome measures. RESULTS: After PSM, each confounding factor was evenly distributed between groups, and 75 pairs of patients were successfully matched. The incidence of intra-abdominal infectious complications was significantly higher in the frail group than in the non-frail group (10.7% vs. 1.3%, P < 0.05). There were no significant differences in ICU admission rate, postoperative length of hospital stay, total length of hospital stay, hospital costs, 30-day mortality rate, or 90-day mortality rate between the two groups (P > 0.05). Our logistic regression analysis result showed that preoperative frailty (OR = 12.014; 95% CI: 1.334-108.197; P = 0.027) was an independent factor for intra-abdominal infection. CONCLUSIONS: The presence of preoperative frailty elevated the risk of postoperative intra-abdominal infectious complications in patients undergoing CRC surgery. Therefore, medical staff should assess preoperative frailty in patients with CRC early and provide targeted prehabilitation interventions.

PURPOSE: To determine the effectiveness of vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) in patients undergoing open abdomen management (OAM). METHODS: Data from cases with OAM for at least five days who were admitted to our institution between January 2011 and December 2020 were included. We compared the patient's age, sex, medical history, indication for initial surgery, APACHE II scores, indication for OAM, operative time, intraoperative blood loss, intraoperative transfusion, success of primary fascial closure (rectus fascial closure and bilateral anterior rectus abdominis sheath turnover flap method), success of planned ventral hernia, duration of OAM, and in-hospital mortality between patients undergoing VAWCM (VAWCM cases, n = 27) and vacuum-assisted wound closure (VAWC) alone (VAWC cases, n = 25). RESULTS: VAWCM cases had a significantly higher success rate of primary fascial closure (70% vs. 36%, p = 0.030) and lower in-hospital mortality (26% vs. 72%, p = 0.002) than VAWC cases. A multivariate logistic regression analysis showed that VAWCM was an independent factor influencing in-hospital mortality (odds ratio, 0.14; 95% confidence interval: 0.04-0.53; p = 0.004). CONCLUSION: VAWCM is associated with an increased rate of successful primary fascial closure and may reduce in-hospital mortality.
RESUMO
PURPOSE: Pancreatoduodenectomy (PD) is a highly invasive procedure. Intra-abdominal infections and pancreatic fistulas are strongly correlated complications. In the present study, we identified the risk factors for postoperative early drain colonization (POEDC) and established a perioperative management strategy. METHODS: A total of 205 patients who underwent pancreatoduodenectomy were included in the study. POEDC was defined as a positive drain fluid culture before postoperative day (POD) 4. We retrospectively investigated the correlation between POEDC, postoperative outcomes, and clinical factors. RESULTS: POEDC was observed in 26 patients (12.6%) with poor postoperative outcomes, including pancreatic fistulas (P < 0.001). A multivariate analysis demonstrated a correlation between these postoperative outcomes and the age (P = 0.002), body mass index (BMI) (P = 0.002), procalcitonin (PCT) level (P < 0.001), and drain amylase level on POD 1 (P = 0.032). Enterococcus was detected most frequently, being found in 15 patients. CONCLUSION: We observed a strong correlation between POEDC and poor postoperative outcomes. The BMI, age, and PCT and drain amylase level on POD 1 should be considered POEDC risk factors, with the need to propose an antibiotic perioperative strategy. POEDC control may represent the key to improving postoperative outcomes after PD.
