563. Exercise, the Gut Microbiome and Gastrointestinal Diseases: Therapeutic Impact and Molecular Mechanisms.
The benefits of regular physical activity (PA) on disease prevention and treatment outcomes have been recognized for centuries. However, only recently has interorgan communication triggered by the release of "myokines" from contracting skeletal muscles emerged as a putative mechanism by which exercise confers protection against numerous disease states. Cross-talk between active skeletal muscles and the gut microbiota reveal how regular PA boosts host immunity, facilitates a more diverse gut microbiome and functional metabolome, and plays a positive role in energy homeostasis and metabolic regulation. In contrast, and despite the large interindividual variation in the human gut microbiome, reduced microbial diversity has been implicated in several diseases of the gastrointestinal (GI) tract, systemic immune diseases, and cancers. Although prolonged, intense, weight-bearing exercise conducted in extreme conditions can increase intestinal permeability, compromising gut-barrier function and resulting in both upper and lower GI symptoms, these are transient and benign. Accordingly, the gut microbiome has become an attractive target for modulating many of the positive effects of regular PA on GI health and disease, although the precise dose of exercise required to induce favourable changes in the microbiome and enhance host immunity is currently unknown. Future efforts should concentrate on gaining a deeper understanding of the factors involved in exercise-gut interactions through the generation of functional 'omics readouts (ie, metatranscriptomics, metaproteomics, and metabolomics) that have the potential to identify functional traits of the microbiome that are linked to host health and disease states, and validating these interactions in experimental and preclinical systems. A greater understanding of how PA interacts with the GI tract and the microbiome may enable targeted therapeutic strategies to be developed for individuals and populations at risk for a variety of GI diseases.

Gastrointestinal bleeding is a significant cause of morbidity and mortality among emergency unit patients. Several scoring systems are verified for predicting hospitalization and mortality such as Glasgow Blatchford Bleeding Score (GBS), AIMS65 score, Rockall score (RS), and International Bleeding Risk Score (INBS; ABC score). The aim of this study is to evaluate the efficacy and predictive value of these scoring systems.
566. A retrospective, observational study to examine the effect of early tumor necrosis factor inhibitor use on rates of surgery for Crohn's disease in Japan.
Crohn's disease (CD) is an incurable inflammatory condition that often requires multiple surgeries, negatively impacting quality of life. As such, treatment strategies that aim to prevent damage to the bowel and reduce the burden of surgeries for patients with CD are important. This retrospective, long-term, observational study investigated whether tumor necrosis factor inhibitor (TNFi) treatment was associated with decreased rates of abdominal surgery in Japanese patients with CD.

The most important step in endoscope retreatment is careful manual cleaning before disinfection. Selecting the proper brushes is critical to disinfection. The study investigated the effectiveness of a novel double-headed disposable brush for cleaning flexible gastrointestinal endoscopes.

Colorectal cancer (CRC) is a prevalent and lethal malignancy. This study examines differences in clinical and prognostic characteristics of CRC between patients under 50 years and those aged 50 and above, treated at a reference hospital in Southern Brazil.
570. Systematic review and meta-analysis: no evidence that low-dose non-steroidal anti-inflammatory drugs (NSAIDs) reduce the risk of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP).
Currently, many studies focus on the use of high-dose NSAIDs, showing significant effectiveness in preventing post-ERCP pancreatitis after surgery. However, some studies suggest that low-dose NSAIDs can also have certain effects. Nevertheless, after using propensity score matching to balance potential biases, the results do not seem ideal and fail to demonstrate clear effectiveness.
571. Impact of duration to endoscopy in patients with non-variceal upper gastrointestinal bleeding: propensity score matching analysis of real-world data from Thailand.

The findings on mortality, rebleeding rate, and hospital stay in patients who underwent early vs. late endoscopy are conflicting. We aimed to compare in-hospital outcomes and medical resource use in patients with acute non-variceal upper gastrointestinal bleeding.

Tumor blood vessels are tortuous and dilated, contributing to the aberrant tumor microenvironment. CD93 is a newly reported transmembrane receptor, mainly expressed in tumor endothelial cells, that has demonstrated prognostic value in some cancer types. However, the role of CD93 in the vasculature of colorectal cancer (CRC) tissues and its prognostic significance remain unknown. It is therefore necessary to explore the effect of CD93 in patients with CRC.
573. Short- and long-term outcomes of neoadjuvant chemotherapy compared with neoadjuvant chemoradiotherapy for locally advanced rectal cancer: an updated meta-analysis.

Neoadjuvant chemoradiotherapy (NACRT) is the standard treatment regimen for locally advanced rectal cancer (LARC) but has unavoidable radiation toxicity. With the advent of more optimized chemotherapy regimens, neoadjuvant chemotherapy (NAC) is sometimes offered as an alternative to NACRT. The purpose of this meta-analysis was to compare the short- and long-term outcomes of NAC and NACRT for LARC patients.

Sarcopenia, characterized by loss of muscle mass and function, has gained importance in the evaluation of cirrhotic patients. Evidence suggests its role in adverse clinical outcomes, including minimal hepatic encephalopathy (MHE). This study aimed to investigate the association between sarcopenia and MHE in patients with cirrhosis.

Cyclic vomiting syndrome (CVS) is a phasic disorder of gut-brain interaction characterized by episodes of severe nausea and vomiting. In-depth qualitative research on phase-specific CVS symptoms and impacts is lacking. The study objectives were to explore the experience of patients with CVS in the United States and to identify CVS symptoms and impacts on adults, adolescents, and caregivers.

Pancreatic ductal adenocarcinoma (PDAC) has a complex tumor microenvironment enriched with tumor-associated macrophages. Triggering receptor expressed on myeloid cells 2 (TREM2) is highly expressed by a subset of macrophages in PDAC. However, the functional role of TREM2 in PDAC progression remains elusive.
