INTRODUCTION: Accurate risk prediction can facilitate screening and early detection of pancreatic cancer (PC). We conducted a systematic review to critically evaluate effectiveness of machine learning (ML) and artificial intelligence (AI) techniques applied to Electronic Health Records (EHR) for PC risk prediction. METHODS: Ovid MEDLINE(R), Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, Scopus, and Web of Science were searched for articles that utilized ML/AI techniques to predict PC, published between January 1st, 2012 to February 1st, 2024...

BACKGROUND: It is unknown whether concomitant esophageal involvement or anatomic location of eosinophilic infiltration impact the natural history of eosinophilic gastrointestinal disease (EGID). METHODS: A retrospective cohort study was performed utilizing the University of North Carolina EGID Clinicopathologic Database. Patients were adults and children with a prior EGID diagnosis based on clinicopathologic features. Demographics, clinical characteristics, treatment information, and procedural data were extracted from medical records...

OBJECTIVES: The early detection of gastric neoplasms (GNs) leads to favorable treatment outcomes. The latest endoscopic system, EVIS X1, includes third-generation narrowband imaging (3G-NBI), texture and color enhancement imaging (TXI), and high-definition white-light imaging (WLI). Therefore, this randomized phase II trial aimed to identify the most promising imaging modality for GN detection using 3G-NBI and TXI. METHODS: Patients with scheduled surveillance endoscopy after a history of esophageal cancer or GN or preoperative endoscopy for known esophageal cancer or GN were randomly assigned to the 3G-NBI, TXI, or WLI groups...

OBJECTIVES: Hepatitis B virus (HBV) vaccination is recommended in patients with inflammatory bowel disease (IBD). Although the two-dose Heplisav-B vaccine has proven effective, more than 20% of patients with IBD do not seroconvert. We prospectively evaluated the effectiveness of a third Heplisav-B dose in patients with IBD lacking HBV immunity despite two-dose vaccination. METHODS: Adults with IBD who had received two-dose Heplisav-B vaccination between 2018-2023 were identified...

BACKGROUND AND AIMS: Personalized management strategies are pivotal in addressing Irritable Bowel Syndrome (IBS). This multicenter randomized controlled trial focuses on comparing the efficacy of a microbiome-based artificial intelligence (AI)-assisted personalized diet (PD) with a low FODMAP diet (LFD) for IBS management. METHODS: One hundred and twenty-one patients participated, with 70 assigned to the PD group and 51 to the LFD group. IBS subtypes, demographics, symptom severity (IBS-SSS), anxiety, depression, and quality of life (IBS-QOL) were evaluated...

OBJECTIVE: Bile acid diarrhea (BAD) is an underrecognized and socially debilitating disease caused by high concentrations of bile acids in the colon. Bile acids directly and indirectly promote carcinogenesis. Here, we investigated if individuals with BAD have an increased risk of gastrointestinal (GI) cancers. DESIGN: By using the Danish health registries, adult individuals with BAD were identified by international classification of disease 10th revision (ICD10) code K90...

INTRODUCTION: Excess weight is an established risk factor for colorectal cancer (CRC). However, evidence is lacking on how its impact varies by polygenic risk at different stages of colorectal carcinogenesis. METHODS: We assessed the individual and joint associations of body mass index (BMI) and polygenic risk scores (PRSs) with findings of colorectal neoplasms among 4,784 participants of screening colonoscopy. Adjusted odds ratios (aORs) for excess weight derived by multiple logistic regression were converted to genetic risk equivalents (GREs) to quantify the impact of excess weight compared to genetic predisposition...

BACKGROUND: Preliminary data suggest that an encapsulated balloon (EsoCheckTM), coupled with a two methylated DNA biomarker panel (EsoGuardTM), detects Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) with high accuracy. The initial assay required sample freezing upon collection. AIM: Assess a next-generation EsoCheck sampling device and EsoGuard assay in a much-enlarged multicenter study clinically enhanced by utilizing a CLIA-compliant assay and samples maintained at room temperature...

BACKGROUND: Indeterminate liver nodules (ILNs) are frequently encountered on diagnostic imaging after positive hepatocellular carcinoma (HCC) surveillance results, but their natural history remains unclear. METHODS: We conducted a multi-center retrospective cohort study among patients with ≥1 newly detected LI-RADS 3 (LR-3) lesion ≥1 cm or LI-RADS 4 (LR-4) lesion of any size (per LI-RADS v2018) between January 2018 and December 2019. Patients were followed with repeat imaging at each site per institutional standard of care...

INTRODUCTION: This trial was to shorten the duration of both vasoconstrictors and prophylactic antibiotics to only 2 days in the therapy of acute gastroesophageal variceal hemorrhage. METHODS: After successful endoscopic hemostasis of gastroesophageal variceal hemorrhage, eligible patients were randomized to receive terlipressin infusion 1 mg per 6 hours and ceftriaxone 1 g daily for 5 days (group A) or a similar regimen for 2 days (group B). Primary end points were very early rebleeding at 5 days, and secondary end points included 48-hour hemostasis, 42-day rebleeding, and hospitalization days...

OBJECTIVE: To evaluate the effect of Embrella, a novel-designed colonoscopic distal attachment, on adenoma detection rate (ADR) and adenoma per colonoscopy (APC), compared with standard colonoscopy in routine practice. METHODS: All consecutive patients who underwent routine colonoscopic examinations at three endoscopy centers in China were enrolled. Participants were randomly assigned in a 1:1 ratio to the Embrella-assisted colonoscopy (EAC) or standard colonoscopy (SC) groups...

OBJECTIVES: There is limited longitudinal data on the impact of chronic therapy on the natural history of eosinophilic esophagitis [EoE], a chronic allergic disease of the esophagus. The purpose of this study was to evaluate if patients with well-controlled EoE were less likely to develop fibrostenotic complications. METHODS: Subjects were identified from a database of pediatric EoE patients at the Children's Hospital of Philadelphia started in 2000. Patients were then searched in adult medical records to identify patients who transitioned care...

OBJECTIVE: Assessing the cumulative degree of bowel injury in ileal Crohn's disease (CD) is difficult. We aimed to develop machine learning (ML) methodologies for automated estimation of cumulative ileal injury on CT-enterography (CTE) to help predict future bowel surgery. METHODS: Adults with ileal CD using biologic therapy at a tertiary care center underwent ML analysis of CTE scans. Two fellowship trained radiologists graded bowel injury severity at granular spatial increments along the ileum (1cm), called mini-segments...
