Article Abstract

Objectives: The hypertriglyceridaemic waist (HTGW) phenotype, an indicator to assess metabolic syndrome, could be a useful predictive marker for the risk of acute pancreatitis. This study aimed to evaluate the association between the HTGW phenotype and the risk of acute pancreatitis with a nationwide population-based cohort.

Design: A retrospective, nationwide cohort study.

Setting: Registry of health check-up result from Korean National Health Insurance Service.

Participants: A total of 3 912 551 adults who underwent health checkups under the National Health Insurance Service in 2009 were enrolled in this study.

Interventions: Subjects with both increased waist circumference (WC) and elevated blood triglyceride concentrations were defined as the HTGW phenotype. The participants were divided into four groups, classified as NWNT (normal WC-normal triglycerides), EWNT (elevated WC-normal triglycerides), NWET (normal WC-elevated triglycerides) and HTGW. The WC triglyceride index (WTI) is a quantitative indicator of the HTGW phenotype which is calculated by multiplying WC (cm) by triglyceride levels (mmol/L).

Primary Outcome Measure: The subjects were followed until 31 December 2018. The adjusted HRs of acute pancreatitis in each group were estimated.

Results: During the follow-up, there were a total of 8933 of acute pancreatitis occurrences. The incidence of acute pancreatitis in all subjects was 0.278 per 1000 person-year. The HTGW group had the highest incidence (0.444), followed by the NWET (0.381), and EWNT (0.316) groups. The HTGW group had a significant higher incidence of acute pancreatitis than the NWNT groups (HR 1.364 (95% CI 1.279 to 1.454)). The risk of acute pancreatitis steadily increased as the WTI increased (HR 1.847 (95% CI 1.657 to 2.058) in 10th decile).

Conclusions: The HTGW phenotype is confirmed to be an independent risk factor that increases the risk of acute pancreatitis.

Background: Current scoring systems for hypertriglyceridaemia-induced acute pancreatitis (HTG-AP) severity are few and lack reliability. The present work focused on screening predicting factors for HTG-SAP, then constructing and validating the visualization model of HTG-AP severity by combining relevant metabolic indexes.

Methods: Between January 2020 and December 2024, retrospective clinical information for HTG-AP inpatients from Weifang People's Hospital was examined.

Background: Severe acute pancreatitis (SAP) is a life-threatening condition requiring early risk stratification. While the Bedside Index for Severity in Acute Pancreatitis (BISAP) is widely used, its reliance on complex parameters limits its applicability in resource-constrained settings. This study introduces a decision tree model based on Classification and Regression Tree (CART) analysis, utilizing Neutrophil-to-Lymphocyte Ratio (NLR) and C-reactive Protein (CRP), as a simpler alternative for early SAP prediction.

Purpose: In this retrospective study, whether [Ga]Ga-DOTA-FAPI-04 PET/MR imaging biomarkers can predict the progression-free survival (PFS) and overall survival (OS) of patients with advanced pancreatic cancer was investigated.

Methods: Fifty-one patients who underwent [Ga]Ga-DOTA-FAPI-04 PET/MR scans before first-line chemotherapy were recruited. Imaging biomarkers, including the maximum tumor diameter, minimum apparent diffusion coefficient (ADC), maximum and mean standardized uptake values (SUV and SUV), fibroblast activation protein- (FAP-) positive tumor volume (FTV and W-FTV) and total lesion FAP expression (TLF and W-TLF), were recorded for primary and whole-body tumors.

Objective: To validate and assess clinical efficacy of a prognostic model for predicting severe acute pancreatitis (SAP) based on inflammatory markers (IL-6, ΔIL-22), thromboelastography parameters (K-time) and the BISAP score.

Material And Methods: A prospective observational cohort study enrolled 181 patients with acute pancreatitis. Serum IL-6 and IL-22 were measured in 24 and 48 hours after clinical manifestation, respectively.

Objective: To analyze the most well-known studies devoted to completion pancreatectomy (CP) for postoperative complications after pancreatoduodenectomy.

Material And Methods: We analyzed original articles and reviews between 1992 and 2023 (number of patients ≥5 (5-120)).

Results: Mean blood loss in CP ranged from 500 to 2180 ml, surgery time - from 144 to 340 min.
