Introduction: Perioperative goal-directed therapy (PGDT) may improve postoperative outcome in high-risk surgery patients but its adoption has been slow. In 2012, we initiated a performance improvement (PI) project focusing on the implementation of PGDT during high-risk abdominal surgeries. The objective of the present study was to evaluate the effectiveness of this intervention.
Methods: This is a historical prospective quality improvement study. The goal of this initiative was to standardize the way fluid management and hemodynamic optimization are conducted during high-risk abdominal surgery in the Departments of Anesthesiology and Surgery at the University of California Irvine. For fluid management, the protocol consisted in standardized baseline crystalloid administration of 3 ml/kg/hour and any additional boluses based on PGDT. The impact of the intervention was assessed on the length of stay in the hospital (LOS) and post-operative complications (NSQIP database).
Results: In the 1 year pre- and post-implementation periods, 128 and 202 patients were included. The average volume of fluid administered during the case was 9.9 (7.1-13.0) ml/kg/hour in the pre-implementation period and 6.6 (4.7-9.5) ml/kg/hour in the post-implementation period (p < 0.01). LOS decreased from 10 (6-16) days to 7 (5-11) days (p = 0.0001). Based on the multiple linear regression analysis, the estimated coefficient for intervention was 0.203 (SE = 0.054, p = 0.0002) indicating that, with the other conditions being held the same, introducing intervention reduced LOS by 18% (95% confidence interval 9-27%). The incidence of NSQIP complications decreased from 39% to 25% (p = 0.04).
Conclusion: These results suggest that the implementation of a PI program focusing on the implementation of PGDT can transform fluid administration patterns and improve postoperative outcome in patients undergoing high-risk abdominal surgeries.

Superficial duodenal epithelial tumors were previously considered rare. Laparoscopic and endoscopic cooperative surgery for duodenal tumors (D-LECS) has been developed to achieve successful endoscopic treatment. Patients who have undergone living-donor liver transplantation (LDLT) may have severe abdominal adhesions, and immunosuppressive agents (IAs) may affect the degree of postoperative abdominal adhesions and wound healing, but their effects remain unclear.

Background: Non-alcoholic fatty liver disease (NAFLD) is a common chronic liver disease with a high prevalence. Recent data suggest that NAFLD may be an independent risk factor for cardiovascular disease (CVD). This study aimed to investigate the association between NAFLD and carotid high-risk plaque (HRP) as assessed by high-resolution magnetic resonance imaging (MRI), and to examine the diagnostic value of NAFLD.

Background: This study compared anatomical imaging features between high-risk and non-high-risk groups in neuroblastoma with at least one image-defined risk factor (IDRF). It also assessed the diagnostic performance of these features in identifying the high-risk group.
Methods: A retrospective analysis of neuroblastoma patients with at least one IDRF was conducted.

Emerging evidence has shown that the N-methyladenosine (mA) modification of RNA plays key roles in tumorigenesis and the progression of various cancers. However, the potential roles of the mA modification of long noncoding RNAs (lncRNAs) in pancreatic cancer (PaCa) are still unknown. To analyze the prognostic value of mA-related lncRNAs in PaCa, an m6A-related lncRNA signature was constructed as a risk model via Pearson's correlation and univariate Cox regression analyses in The Cancer Genome Atlas (TCGA) database.

Symptomatic abdominal aortic aneurysms carry significant mortality risk. This is supplemented by the Royal College of Emergency Medicine guidelines which suggest imaging for patients 50 years of age or older presenting with unexplained abdominal, flank, or back pain. This study aimed to evaluate the prevalence and mortality rates of patients with symptomatic abdominal aortic aneurysms in a high-risk population and to assess scanning rates in the accident and emergency department.
