Abstract
The 21st century has started with several innovations in the medical sciences, with wide applications in health care management. This development has taken in the field of medicines (newer drugs/molecules), various tools and technology which has completely changed the patient management including abdominal surgery. Surgery for abdominal diseases has moved from maximally invasive to minimally invasive (laparoscopic and robotic) surgery. Some of the newer medicines have its impact on need for surgical intervention. This article focuses on the development of these emerging molecules, tools, and technology and their impact on present surgical form and its future effects on the surgical intervention in gastroenterological diseases.

Abstract
PURPOSE Children with anorectal malformation (ARM) and Hirschsprung's disease (HD) often experience bowel symptoms into adulthood, despite definitive surgery. This study evaluates the quality of life (QOL) and bowel functional outcome of children treated for ARM and HD in comparison to healthy controls. METHODS Between December 2020 and February 2023, we recruited patients with ARM and HD aged 3-17 years at four tertiary referral centres, who had primary corrective surgery done >12 months prior. Healthy controls were age-matched and sex-matched. All participants completed the Pediatric Quality of Life Inventory Generic Core Scales 4.0, General Well-Being (GWB) Scale 3.0 and Family Impact (FI) Module 2.0 Questionnaires. Bowel Function Score (BFS) Questionnaires were also administered. We also performed subgroup analysis according to age categories. Appropriate statistical analysis was performed with p<0.05 significance. Ethical approval was obtained. RESULTS There were 306 participants: 101 ARM, 87 HD, 118 controls. Patients with ARM and HD had significantly worse Core and FI Scores compared with controls overall and in all age categories. In the GWB Scale, only ARM and HD adolescents (13-17 years) had worse scores than controls. ARM and HD had significantly worse BFSs compared with controls overall and in all age categories. There was significant positive correlation between BFS and Core Scores, GWB Scores and FI Scores. CONCLUSION Patients with ARM and HD had worse QOL than controls. Lower GWB Scores in adolescents suggests targeted interventions are necessary. Bowel function influences QOL, indicating the need for continuous support into adulthood.

Abstract
Paediatric-onset inflammatory bowel disease (IBD) is a complex and heterogenous condition. Incidence of disease in those aged <18 years has doubled over the last 25 years, with concurrent increased prevalence and no decrease in disease severity. The tools available at diagnosis for investigation have developed over the last 10 years, including better utilisation of faecal calprotectin, improved small bowel imaging and video capsule endoscopy. Alongside this, management options have increased and include biological and small molecule therapies targeting alternative pathways (such as interleukin 12/23, integrins and Janus kinase/signal transducers and activators of transcription, JAK-STAT pathways) and better understanding of therapeutic drug monitoring for more established agents, such as infliximab. Dietary manipulation remains an interesting but contentious topic.This review summarises some of the recent developments in the diagnosis, investigation and management of IBD in children and young people. IBD is increasingly recognised as a continuum of disease, with a proportion of patients presenting with classical Crohn's disease or ulcerative colitis phenotypes. Future implementation of personalisation and stratification strategies, including clinical and molecular biomarkers, implementation of predictors of response and outcome and use of additional therapies, will continue to require working within clinical networks and multiprofessional teams.

Abstract
BACKGROUND Many women grow up dreaming of becoming doctors, preferring specialties that allow more focus on time outside the hospital and on family life. Nowadays, specialties, like gastroenterology, have still a significant gender gap. METHODS Based on this known discrepancy, a web-based questionnaire was designed by the Young Component of the Scientific Committee of the Federation of Italian Scientific Societies of Digestive Diseases 2023 (FISMAD) to examine the current situation of female gastroenterologists in Italy. The survey, designed specifically for this study, was sent by email to all female gastroenterologists and residents gastroenterologists, members of the three major Italian societies of Gastroenterology. RESULTS A total of 423 female physicians responded to the survey: 325 (76.8%) had full-time employment, and only a few had an academic career (7.2%). The main occupations were outpatient clinics (n = 288, 68%) and diagnostic endoscopy (n = 289, 68.3%); only 175 (41.3%) performed interventional endoscopy. One hundred and forty-seven (34.7%) had the chance to attend a master in advanced or interventional endoscopy, while 133 (31.4%) faced disadvantages that enabled them to attend. Of the 244 (58%) who reported feeling underappreciated, 194 (79.5%) said it was due to gender bias. We found that women doctors considered themselves disadvantaged compared with men doctors due to career opportunities (n = 338), salary negotiations (n = 64), and training opportunities (n = 144). CONCLUSIONS In conclusion, gastroenterology still has a long way to go before approaching greater gender parity.

Abstract
Autism spectrum disorder (ASD) is a multifactorial, pervasive neurodevelopmental disorder affecting 1 in 36 children in the United States. Given the rising prevalence and significant economic and social costs associated with ASD, it is critical that continued efforts be made towards better understanding the underlying etiology as well as management of the condition and its commonly associated comorbidities. It has been estimated that upwards of 70% of children with ASD have a positive history of gastrointestinal (GI) symptoms. In this retrospective, descriptive study, we identified 131 patients with diagnosis of autism spectrum disorder who presented for initial evaluation by pediatric gastroenterology at the Baystate Children's Specialty Center. We collected data from chart review of these patients with a particular focus on reason for referral, components of evaluation as well as results of said evaluation. Of the 131 patients, the most frequent reason for referral included constipation (42.7%), abdominal pain (27.5%), and feeding difficulties (26.7%). After completion of the evaluation, 60.3% of patients were ultimately diagnosed with a functional gastrointestinal condition. Of patients who completed endoscopic evaluation, 40% of patients were found to have grossly abnormal and 40% were found to have pathologically abnormal EGD. The majority of patients were recommended to have diagnostic evaluation; however, a large proportion of them were unable to complete said evaluation. The majority of patients were found to have abnormal testing; however, the majority of patients were additionally diagnosed with a functional gastrointestinal condition.

Abstract
INTRODUCTION Metabolic dysfunction-associated fatty liver disease (MASLD) is the hepatic manifestation of metabolic syndrome and the leading cause of chronic liver disease worldwide. Given that there is no pharmacological treatment for MASLD, it is imperative to understand whether lifestyle modifications may improve biochemical and pathological outcomes. One commonly proposed dietary modification is the Mediterranean diet; however, vegetarianism may also be a promising intervention. Vegetarianism has been shown to be associated with reduced morbidity and mortality in metabolic syndrome outcomes in coronary artery disease and diabetes; however, the relationship between vegetarian diet and MASLD is less clear. In this scoping review, we will provide a comprehensive overview of the current body of evidence related to a vegetarian diet and MASLD. METHODS AND ANALYSIS The aim of this scoping review is to describe and summarise the current body of evidence related to MASLD and a vegetarian diet. This review will be conducted using Arksey and O'Malley's framework. The literature review will be conducted using the following databases: SCOPUS, Web of Science, CINAHL-Plus, Cochrane Library and Medline. No restriction will be made on publication date. Included studies will encompass clinical trials and observational designs that examine effects or association of vegetarian diet in adults (≥16 years) and report on the incidence, prevalence or progression of MASLD. Grey literature, non-human studies and articles focusing on changes in a specific food or nutraceutical will be excluded. Articles must have an English-language abstract available to be considered for inclusion. Screening and data extraction will be conducted by two independent reviewers. The findings will be summarised with descriptive statistics. ETHICS AND DISSEMINATION Approval from a medical ethics committee is not required for this review. Once the review is complete, the findings will be submitted to a peer-reviewed journal.

Abstract
Fibroblast growth factor 15/19 (FGF15/19, mouse/human ortholog) is expressed in the ileal enterocytes of the small intestine and released postprandially in response to bile acid absorption. Previous reports of FGF15-/- mice have limited our understanding of gut-specific FGF15's role in metabolism. Therefore, we studied the role of endogenous gut-derived FGF15 in bile acid, cholesterol, glucose, and energy balance. We found that circulating levels of FGF19 were reduced in individuals with obesity and comorbidities, such as type 2 diabetes and metabolic dysfunction-associated fatty liver disease. Gene expression analysis of ileal FGF15-positive cells revealed differential expression during the obesogenic state. We fed standard chow or a high-fat metabolic dysfunction-associated steatohepatitis-inducing diet to control and intestine-derived FGF15-knockout (FGF15INT-KO) mice. Control and FGF15INT-KO mice gained similar body weight and adiposity and did not show genotype-specific differences in glucose, mixed meal, pyruvate, and glycerol tolerance. FGF15INT-KO mice had increased systemic bile acid levels but decreased cholesterol levels, pointing to a primary role for gut-derived FGF15 in regulating bile acid and cholesterol metabolism when exposed to obesogenic diet. These studies show that intestinal FGF15 plays a specific role in bile acid and cholesterol metabolism regulation but is not essential for energy and glucose balance.

Abstract
BACKGROUND Functional constipation (FC) in children is a common gastrointestinal disorder with a worldwide-pooled prevalence of 9.5%. Complaints include infrequent bowel movements, painful defecation due to hard and/or large stools, faecal incontinence, and abdominal pain. Prebiotic oligosaccharides have been shown to relieve constipation symptoms in young adults and elderly. However, sufficient evidence is lacking linking additional prebiotic intake to improve symptoms in children with FC. We hypothesise that prebiotic oligosaccharides are able to relieve symptoms of constipation in young children as well. METHODS In the present randomised, double-blind, placebo-controlled, multi-centre study, we will study the effects of two prebiotic oligosaccharides in comparison to placebo on constipation symptoms in children of 1-5 years (12 to 72 months) of age diagnosed with FC according to the Rome IV criteria for functional gastrointestinal disorders. The primary outcome measure will be change in stool consistency. Secondary outcomes include stool frequency and stool consistency in a number of cases (%). Tertiary outcomes include among others painful defecation, use of rescue medication, and quality of life. In addition, the impact on gut microbiome outcomes such as faecal microbiota composition and metabolites will be investigated. Participants start with a run-in period, after which they will receive supplements delivered in tins with scoops for 8 weeks, containing one of the two prebiotic oligosaccharides or placebo, followed by a 4-week wash-out period. DISCUSSION This randomised double-blind, placebo-controlled multi-centre study will investigate the effectiveness of prebiotic oligosaccharides in children aged 1-5 years with FC.

Abstract
INTRODUCTION Hepatic encephalopathy (HE) is a major complication of acute liver failure, cirrhosis and transjugular intrahepatic portosystemic shunt (TIPS) placement. Its clinical manifestations range from mild cognitive deficits to coma. Furthermore, HE is a financial burden to a patient's family and significantly affects the patient's quality of life. In clinical practice, proton pump inhibitors (PPIs) are widely used for the treatment of HE. The use of PPIs is associated with an increased risk of post-TIPS HE; however, findings on the risk relationship between PPIs and post-TIPS HE are inconsistent. Therefore, a systematic evaluation of the relationship is needed to further provide valid evidence for the rational use of PPIs in patients who undergo TIPS. METHODS AND ANALYSIS PubMed, Web of Science, Cochrane Library and Embase will be searched extensively for relevant information. Information from 1 July 2023 to 31 July 2023 in these databases will be included. Primary outcomes will be the use of PPIs and incidence of HE after TIPS; secondary outcomes will be survival, dose dependence and adverse events. This meta-analysis will be reported in accordance with the 50 Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020. The risk of bias, heterogeneity and quality of evidence of the included studies will be evaluated prior to the data analysis. All data will be analysed using Review Manager (V.5.4.1) and Stata (V.17.0) statistical software. ETHICS AND DISSEMINATION Ethical approval will not be necessary for this review and meta-analysis. The results of the study will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER CRD42022359208.

Abstract
Neutrophil (PMN) tissue accumulation is an established feature of ulcerative colitis (UC) lesions and colorectal cancer (CRC). To assess the PMN phenotypic and functional diversification during the transition from inflammatory ulceration to CRC we analyzed the transcriptomic landscape of blood and tissue PMNs. Transcriptional programs effectively separated PMNs based on their proximity to peripheral blood, inflamed colon, and tumors. In silico pathway overrepresentation analysis, protein-network mapping, gene signature identification, and gene-ontology scoring revealed unique enrichment of angiogenic and vasculature development pathways in tumor-associated neutrophils (TANs). Functional studies utilizing ex vivo cultures, colitis-induced murine CRC, and patient-derived xenograft models demonstrated a critical role for TANs in promoting tumor vascularization. Spp1 (OPN) and Mmp14 (MT1-MMP) were identified by unbiased -omics and mechanistic studies to be highly induced in TANs, acting to critically regulate endothelial cell chemotaxis and branching. TCGA data set and clinical specimens confirmed enrichment of SPP1 and MMP14 in high-grade CRC but not in patients with UC. Pharmacological inhibition of TAN trafficking or MMP14 activity effectively reduced tumor vascular density, leading to CRC regression. Our findings demonstrate a niche-directed PMN functional specialization and identify TAN contributions to tumor vascularization, delineating what we believe to be a new therapeutic framework for CRC treatment focused on TAN angiogenic properties.

Abstract
Introduction Mobile Health (mHealth) applications allow for new possibilities and opportunities in patient care. Their potential throughout the whole patient journey is undisputed. However, the eventual adoption by patients depends on their acceptance of and motivation to use mHealth applications as well as their adherence. Therefore, we investigated the motivation and drivers of acceptance for mHealth and developed an adapted model of the Unified Theory of Acceptance and Use of Technology (UTAUT2). Methods We evaluated 215 patients with chronic gastroenterological diseases who answered a questionnaire including all model constructs with 7-point Likert scale items. Our model was adapted from the Unified Theory of Acceptance and Use in Technology 2 and includes influencing factors such as facilitating conditions, performance expectancy, hedonic motivation, social influence factors, effort expectancy, as well as personal empowerment and data protection concerns. Model evaluation was performed with structural equation modelling with PLS-SEM. Bootstrapping was performed for hypothesis testing. Results and Conclusion Patients had a median age of 55.5 years, and the gender ratio was equally distributed. Forty percent received a degree from a university, college, technical academy, or engineering school. The majority of patients suffered from chronic liver disease, but patients with inflammatory bowel diseases, GI cancers, and pancreatic diseases were also included. Patients considered their general technology knowledge as medium to good or very good (78%). Actual usage of mHealth applications in general was rare, while the intention to use them was high. The leading acceptance factor for mHealth applications in our patient group was feasibility, both in terms of technical requirements and the intuitiveness and manageability of the application. Concerns about data privacy did not significantly impact the intention to use mobile devices. Neither the gamification aspect nor social influence factors played a significant role in the intention to use mHealth applications. Interpretation Most of our patients were willing to spend time on a mHealth application specific to their disease on a regular basis. Acceptance and adherence are ensured by efficient utilization that requires minimum effort and compatible technologies as well as support in case of difficulties. Social influence and hedonic motivation, which were part of UTAUT2, as well as data security concerns, were not significantly influencing our patients' intention to use mHealth applications. A literature review revealed that drivers of acceptance vary considerably among different population and patient groups. Therefore, healthcare and mHealth providers should put effort into understanding their specific target groups' drivers of acceptance. We provided those for a cohort of patients from gastroenterology in this project.

Abstract
INTRODUCTION Gastro-oesophageal reflux disease (GORD) is a chronic progressive disease, associated with substantial clinical and economic burden. Proton pump inhibitors (PPIs) are considered first-line treatment; however, there are concerns around the long-term impact of their usage. Surgical treatment with Nissen fundoplication can be considered but, because of the potential side effects, few patients undergo surgery and there remains a substantial therapeutic gap within the current treatment pathway. Laparoscopic magnetic sphincter augmentation (MSA) using the LINX® device is an alternative surgical approach. METHODS The objective of this study was to investigate patient-reported outcomes following laparoscopic MSA surgery using the LINX® device in a UK setting. A retrospective questionnaire obtained data regarding postoperative symptoms, medication use and patient satisfaction. RESULTS Out of 131 patients surveyed, 97 responses were received, with a minimum follow-up time of 1 year. In those who reported heartburn and regurgitation preoperatively, improvement was reported in 93% (84/90) and 90% (86/96) of patients, respectively. Eighty-eight per cent (73/83) of patients were able to completely stop or reduce their medication by at least 75%. Seventy-seven per cent (73/95) of patients were "very satisfied" or "satisfied". CONCLUSIONS This study is the first to present patient-reported outcomes of MSA using the LINX® device for patients with GORD in the UK. It demonstrates that the device has favourable outcomes and could effectively bridge the current therapeutic gap that exists between PPI medication and Nissen fundoplication.

Abstract
A woman in her late 50s on mycophenolate for limited systemic sclerosis presented with abdominal pain. Vital signs and investigative evaluations were normal. Cross-sectional imaging identified gastric and small bowel wall thickening, free fluid, and pneumoperitoneum. In the operating room, a small bowel perforation was found and resected. Postoperatively, immunosuppression was held and she completed a course of amoxicillin/clavulanate. She discharged home and re-presented on postoperative day 8 with seizures and was found to have a frontal brain mass which was biopsied. Pathology from both the resected bowel and brain biopsy demonstrated Epstein-Barr virus-positive B-cell lymphoproliferative disorder with polymorphic B-cell features. The patient's immunosuppression was discontinued, and she was enrolled in a clinical trial for chemotherapy. Lymphoproliferative disorder can present years after immunosuppression initiation with either spontaneous perforation or solid tumour. Pathological assessment determines treatment options. Heightened concern for atypical clinical presentations in immunosuppressed patients is always warranted.

Abstract
Autoimmune disorders have a wide spectrum of symptoms, often with multiorgan involvement. Multiple autoimmune disorders also often occur concurrently in the same patient. These two possibilities must be distinguished in patients with multiorgan involvement to ensure early diagnosis and treatment. Here, we report a case of a previously healthy man who presented with simultaneous Takayasu arteritis and Crohn's disease. He presented with heart failure with reduced ejection fraction and severe aortic regurgitation. An echocardiogram demonstrated a greatly dilated aorta, and a diagnosis of Takayasu arteritis was made, confirmed with CT aortogram. Inpatient treatment was begun, but the patient subsequently developed bloody diarrhoea a few days after admission. Colonoscopy done to locate the source of bleeding showed colonic ulcers; a biopsy confirmed a diagnosis of Crohn's disease. The patient was successfully managed with medical management of heart failure, steroids, mesalamine and azathioprine, and has been in remission for the last 2 years.

Abstract
Bacterial translocation from the gut microbiota is a source of sepsis in susceptible patients. Previous work suggests that overgrowth of gut pathobionts, including Klebsiella pneumoniae, increases the risk of disseminated infection. Our data from a human dietary intervention study found that in the absence of fiber, K. pneumoniae bloomed during microbiota recovery from antibiotic treatment. We thus hypothesized that dietary nutrients directly support or suppress colonization of this gut pathobiont in the microbiota. Consistent with our human subject study, complex carbohydrates in dietary fiber suppressed colonization of K. pneumoniae and allowed for recovery of competing commensals in mouse modeling. In contrast, through ex-vivo and in vivo modeling, we identify simple carbohydrates as a limiting resource for K. pneumoniae in the gut. As proof of principle, supplementation with lactulose, a non-absorbed simple carbohydrate and an FDA approved therapy, increased colonization of K. pneumoniae. Disruption of the intestinal epithelium led to dissemination of K. pneumoniae into the bloodstream and liver, which was prevented by dietary fiber. Our results show that dietary simple and complex carbohydrates are critical not only in the regulation of pathobiont colonization but also disseminated infection, suggesting that targeted dietary interventions may offer a preventative strategy in high-risk patients.

Abstract
Eosinophilic gastroenteritis (EGE) is a rare disease which mainly consists of an abnormal eosinophile infiltration of the gastrointestinal tract. It's classified according to its location: eosinophilic esophagitis, eosinophilic gastritis, eosinophilic enteritis (including duodenum, jejunum and/or ileum) and eosinophilic colitis and degree of infiltration (mucosal, muscular, serosal). Depending on eosinophile concentration, type of EGE and the patient's condition it may manifest with different clinical presentations such as functional dyspepsia, abdominal pain, irritability, hypoproteinemia, diarrhea, anemia, among others. Few research has been done on such an uncommon pathology to the extent that treatment evidence is mostly limited to small case series. This case study reports an infrequent presentation of EGE in the small and large intestine as an undifferentiated gastrointestinal disease and successful corticoid management given to the patient in order to further broaden knowledge on this subject and facilitate an established clinical conduct for the treating physician.

Abstract
Gastrointestinal immune cells, particularly muscularis macrophages (MM) interact with the enteric nervous system and influence gastrointestinal motility. Here we determine the human gastric muscle immunome and its changes in patients with idiopathic gastroparesis (IG). Single cell sequencing was performed on 26,000 CD45+ cells obtained from the gastric tissue of 20 subjects. We demonstrate 11 immune cell clusters with T cells being most abundant followed by myeloid cells. The proportions of cells belonging to the 11 clusters were similar between IG and controls. However, 9/11 clusters showed 578-11,429 differentially expressed genes. In IG, MM had decreased expression of tissue-protective and microglial genes and increased the expression of monocyte trafficking and stromal activating genes. Furthermore, in IG, IL12 mediated JAK-STAT signaling involved in the activation of tissue-resident macrophages and Eph-ephrin signaling involved in monocyte chemotaxis were upregulated. Patients with IG had a greater abundance of monocyte-like cells. These data further link immune dysregulation to the pathophysiology of gastroparesis.

Abstract
OBJECTIVES A deeper understanding of the lived experiences of Hispanic patients with non-alcoholic fatty liver disease (NAFLD) can help guide the development of behavioural programmes that facilitate NAFLD management. This paper explores Hispanic women's experiences living with NAFLD. DESIGN, SETTING, PARTICIPANTS We collected brief sociodemographic questionnaires and conducted in-depth interviews with 12 low-income (all had household income ≤USD$55 000 per year) Hispanic women with NAFLD from the Houston area. Transcripts were audio-recorded and transcribed. We developed a coding scheme and used thematic analysis to identify emergent themes, supported by Atlas.ti. RESULTS Participants identified physicians as their main information source on NAFLD but also consulted the internet, family, friends and peers. Many were still left wanting more information. Participants identified family history, sedentary lifestyles, poor diet and comorbid conditions as causes for their NAFLD. Participants also reported emotional distress after diagnosis. Participants experienced both successes and challenges in making lifestyle changes in nutrition and physical activity. Some participants received desired social support in managing NAFLD, although there were conflicting feelings about spousal support. CONCLUSION Multifaceted programming that improves patient-provider communication, conveys accurate information and enhances social support is needed to support Hispanic women in managing NAFLD.

Abstract
BACKGROUND There are limited studies on the impact of gender on training and career advancement in gastroenterology. AIM The aim was to study this impact and understand the perceptions of work-life balance and beliefs regarding gender dynamics among gastroenterologists in India and other South Asian countries. METHODS A web-based survey was conducted among trainees and attending physicians in South Asia from November 15, 2021, to March 30, 2022. The survey instrument had four components: demographic features, training, career advancement and work-life balance. RESULTS As many as 622 gastroenterologists completed the survey, of which 467 responses were from India (mean age: 41.1 years; females: 11.5%). A higher proportion of female respondents from India believed that gender bias in recruiting and training had negatively impacted their careers (40.7% females vs. 1.5% males). Radiation hazard for fertility (11.1% females vs. 1.9% males, p < 0.001) and as a health concern (14.8% females vs. 5.1% males, p = 0.005) were significant career deterrents for females. A higher proportion of female participants from India faced a career interruption (59.3% females vs. 30.3% males, p ≤ 0.001). Common reasons were pregnancy (37%) and childcare provision (25.9%). More females believed that women were more productive than men (40.8% females vs. 16.9% males, p < 0.001) and that a salary gap existed (44.7% females vs. 29.1% males, p < 0.001). The incidence of self-perceived burnout was 63% among females and 51.6% among males (p = 0.115). CONCLUSION Gender-related factors impact the training and career of female gastroenterologists.

Abstract
Gastrointestinal (GI) complications frequently necessitate intensive care unit (ICU) admission. Additionally, critically ill patients also develop GI complications requiring further diagnostic and therapeutic interventions. However, these patients form a vulnerable group, who are at risk for developing side effects and complications. Every effort must be made to reduce invasiveness and ensure safety of interventions in ICU patients. Artificial intelligence (AI) is a rapidly evolving technology with several potential applications in healthcare settings. ICUs produce a large amount of data, which may be employed for creation of AI algorithms, and provide a lucrative opportunity for application of AI. However, the current role of AI in these patients remains limited due to lack of large-scale trials comparing the efficacy of AI with the accepted standards of care.

Abstract
A male patient in his 30s presented with complaints of acute abdominal pain, black stools and red-coloured urine. CT revealed thrombi in the splenic and left renal veins, leading to infarctions. An endoscopy displayed scalloping of the duodenal folds, indicative of intestinal malabsorption syndrome (IMS). Histopathological examination confirmed IMS. Due to the presence of intravascular haemolysis, haemoglobinuria and thrombotic complications, paroxysmal nocturnal haemoglobinuria (PNH) was suspected and subsequently confirmed by flow cytometry. Thus, a diagnosis of classic PNH with IMS and thrombotic complications was established. This unique case highlights the coexistence of PNH and IMS, resembling the complement hyperactivation, angiopathic thrombosis and protein-losing enteropathy disease, suggesting potential shared pathophysiology.

Abstract
OBJECTIVE To evaluate the impact of a quality improvement project of the adoption of standard parenteral nutrition (SPN) in preterm infants. DESIGN Retrospective, multicentre, whole-population, non-concurrent control study using data from the UK National Neonatal Research Database between 1 January 2014 and 31 December 2020. SETTING Neonatal units in London UK organised by geographical network. PATIENTS Preterm infants <31 weeks' gestation. INTERVENTIONS Introduction of two SPN formulations previously tested in randomised controlled trials (NEON and SCAMP). SCAMP delivers a higher target macronutrient intake. MAIN OUTCOME MEASURES The primary outcome was survival to discharge from neonatal care without major morbidities. Secondary outcomes included the individual components of the primary outcome and a comparison of outcomes between the NEON and the SCAMP formulations. RESULTS Of 6538 eligible infants, 4693 were admitted to neonatal care before and 1845 after the adoption of SPN. Morbidity-free survival decreased by an average of 8.6% (95% CI 5.8% to 11.4%, p<0.0001) following adoption. The effect varied by type of formulation; the cohort that adopted NEON showed no difference in morbidity-free survival, whereas the cohort that adopted SCAMP showed a statistically significant decrease in morbidity-free survival. Overall survival decreased by an average of 2.0% (95% CI 0.01% to 4.0%, p=0.048). CONCLUSIONS Research is urgently needed to identify the optimal composition of parenteral nutrition for preterm babies. This study also adds to the growing body of evidence that suggests that early and high intakes of macronutrients in preterm babies may be harmful.

Abstract
During the three or more years of GI Fellowship, trainees acquire a large percentage of the specialized medical knowledge that they will carry throughout their careers. It is thus important to foster a commitment to continuous learning and practices during fellowship intended to extend beyond training. Since relying solely on traditional textbooks is no longer adequate, numerous valuable resources exist as supplementary aids for learning and studying. Nevertheless, lacking a practical structure to navigate the sheer volume of these resources can be overwhelming. The sources of knowledge in gastroenterology during the digital age include published guidelines, eBooks, podcasts, board examination preparation, mobile applications, and engagement with social media. This article seeks to offer trainees and early career gastroenterologists' guidance for effectively utilizing diverse digital tools for ongoing and lifelong education.

Abstract
Crohn's disease (CD) is a chronic inflammatory gut disorder. Molecular mechanisms underlying the clinical heterogeneity of CD remain poorly understood. MicroRNAs (miRNAs) are important regulators of gut physiology, and several have been implicated in the pathogenesis of adult CD. However, there is a dearth of large-scale miRNA studies for pediatric CD. We hypothesized that specific miRNAs uniquely mark pediatric CD. We performed small RNA-Seq of patient-matched colon and ileum biopsies from treatment-naive pediatric patients with CD (n = 169) and a control cohort (n = 108). Comprehensive miRNA analysis revealed 58 miRNAs altered in pediatric CD. Notably, multinomial logistic regression analysis revealed that index levels of ileal miR-29 are strongly predictive of severe inflammation and stricturing. Transcriptomic analyses of transgenic mice overexpressing miR-29 show a significant reduction of the tight junction protein gene Pmp22 and classic Paneth cell markers. The dramatic loss of Paneth cells was confirmed by histologic assays. Moreover, we found that pediatric patients with CD with elevated miR-29 exhibit significantly lower Paneth cell counts, increased inflammation scores, and reduced levels of PMP22. These findings strongly indicate that miR-29 upregulation is a distinguishing feature of pediatric CD, highly predictive of severe phenotypes, and associated with inflammation and Paneth cell loss.

Abstract
BACKGROUND Colorectal cancer (CRC) is the third highest incidence cancer and is the leading cause of cancer mortality worldwide. Metastasis to distal organ is the major cause of cancer mortality. However, the underlying genetic factors are unclear. This study aimed to identify metastasis-relevant genes and pathways for better management of metastasis-prone patients. METHODS A case-case genome-wide association study comprising 2677 sporadic Chinese CRC cases (1282 metastasis-positive vs 1395 metastasis-negative) was performed using the Human SNP6 microarray platform and analysed with the correlation/trend test based on the additive model. SNP variants with association testing -log10 p value ≥5 were imported into Functional Mapping and Annotation (FUMA) for functional annotation. RESULTS Glycolysis was uncovered as the top hallmark gene set. Transcripts from two of the five genes profiled, hematopoietic substrate 1 associated protein X 1 (HAX1) and hyaluronan-mediatedmotility receptor (HMMR), were significantly upregulated in the metastasis-positive tumours. In contrast to disease-risk variants, HAX1 appeared to act synergistically with HMMR in significantly impacting metastasis-free survival. Examining the subtype datasets with FUMA and Ingenuity Pathway Analysis (IPA) identified distinct pathways demonstrating sexual dimorphism in CRC metastasis. CONCLUSIONS Combining genome-wide association testing with in silico functional annotation and wet-bench validation identified metastasis-relevant genes that could serve as features to develop subtype-specific metastasis-risk signatures for tailored management of patients with stage I-III CRC.

Abstract
OBJECTIVE Gastro-oesophageal reflux disease (GORD) is a common condition affecting children, characterised by the passage of gastric contents into the oesophagus causing pain, vomiting and regurgitation. Children with neurodisability (such as cerebral palsy; CP) are predisposed to more severe GORD due to coexisting gut dysmotility and exclusive/supplementary liquid diet; however, there are no existing tools or outcome measures to assess the severity of GORD in this patient group. For children without CP, the 'Paediatric Gastro-oesophageal Symptom and Quality of Life Questionnaire' (PGSQ) assesses symptoms and response to treatment, but the questions are not suitable for children with significant cognitive impairment. We aimed to adapt the existing PGSQ assessment tool to enable use in evaluating children with CP and GORD. PATIENTS/INTERVENTIONS Cognitive interviews were conducted by the research team with six parents/carers of children (aged 3-15) with CP (Gross Motor Function Classification System level V) who have current or past symptoms of reflux. They were asked to interpret the questionnaire using a 'think-aloud technique,' and offer suggestions on alterations to questions. Reasons for changing questions included confusing/difficult to understand questions, differing interpretations of questions and response choices not applying to the patient group. RESULTS The PGSQ was modified iteratively following each interview. Overall, parents/carers reported that it was acceptable to recall information over the past 7 days. In the final version, it was felt the questions were relevant, useful and related to symptoms that they observed. It was easy to comprehend with no uncomfortable questions. Suggestions for future work included a section specifically focusing on the school day answered by school staff and home life answered by carers who assist them in the home. CONCLUSIONS We have adapted the PGSQ to improve relevance and acceptability for families/carers of children with symptoms of GORD and neurodisability. Further work is needed to validate the questionnaire for this patient group.

Abstract
An early-adolescent boy with a background of Pitt-Hopkins syndrome was transferred to a tertiary paediatric hospital with symptoms of a functional large bowel obstruction. He required extensive surgical intervention including a transverse colectomy, drainage of an abdominal abscess, laparotomy and adhesionolysis, and insertion of a gastrostomy and jejunostomy. He had significant ongoing issues with visceral hyperalgesia that was refractory to a wide range of pharmacological treatments and required admission to the intensive care unit on multiple occasions, and consultations with international experts in Pitt-Hopkins syndrome and pain specialists. An individualised pain plan was created and adjusted over time, with eventual good effect, and he was transferred back to his regional hospital and subsequently discharged home.

Abstract
OBJECTIVE To determine the impact of transanastomotic tube (TAT) feeding in congenital duodenal obstruction (CDO). DESIGN Systematic review with meta-analysis. PATIENTS Infants with CDO requiring surgical repair. INTERVENTIONS TAT feeding following CDO repair versus no TAT feeding. MAIN OUTCOME MEASURES The main outcome was time to full enteral feeds. Additional outcomes included use of parenteral nutrition (PN), cost and complications from either TAT or central venous catheter. Meta-analyses were undertaken using random-effects models (mean difference (MD) and risk difference (RD)), and risk of bias was assessed using the Risk Of Bias In Non-randomised Studies - of Interventions (ROBINS-I) tool. RESULTS Twelve out of 373 articles screened met the inclusion criteria. All studies were observational and two were prospective. Nine studies, containing 469 infants, were available for meta-analysis; however, four were excluded due to serious or critical risk of bias. TAT feeding was associated with reduced time to full enteral feeds (-3.34; 95% CI -4.48 to -2.20 days), reduced duration of PN (-6.32; 95% CI -7.93 to -4.71 days) and reduction in nutrition cost of £867.36 (95% CI £304.72 to £1430.00). Other outcomes were similar between those with and without a TAT including inpatient length of stay (MD -0.97 (-5.03 to 3.09) days), mortality (RD -0.01 (-0.04 to 0.01)) and requirement for repeat surgery (RD 0.01 (-0.03 to 0.05)). CONCLUSION TAT feeding following CDO repair appears beneficial, without increased risk of adverse events; however, certainty of available evidence is low. Earlier enteral feeding and reduced PN use are known to decrease central venous catheter-associated risks while significantly reducing cost of care. PROSPERO REGISTRATION NUMBER CRD42022328381.

Abstract
We present an unusual case of achalasia presenting with dyspnoea and persistent cough. These symptoms persisted for months, leading to the patient undergoing a chest X-ray by her general practitioner which showed right basal consolidation and a density extending along the right mediastinum. CT scan was done which revealed megaoesophagus with a diameter of 7 cm causing tracheal compression, as well as right basal consolidation, consistent with aspiration. Further history revealed 6-month history of progressive swallowing difficulty, retrosternal chest pain and shortness of breath which worsened when eating solid foods. After thorough workup, a diagnosis of idiopathic achalasia (type II) was made. She was treated with laparoscopic Heller cardiomyotomy and Dor fundoplication with significant improvement at follow-up. Dyspnoea and respiratory symptoms are unusual presenting symptoms, suggesting a need to consider achalasia in a wider range of presentations. Successful treatment of achalasia depends on timely diagnosis and intervention prior to oesophageal failure.

Abstract
In recent decades, physicians have diagnosed fictional and non-fictional characters through portraits, biographies and writing. We argue that such an exercise can be beneficial for a uniquely health humanities reason-better understanding of our current world and the social determinants of health. Drawing on the method of health and social justice studies, we explore the character of Shosha, who appears repeatedly in the writings of Nobel Prize winner Isaac Bashevis Singer. Singer's strong story-telling skill and commitment to writing about the Jewish communities of prewar Poland in vivid detail preserve a slice of history, ensure that future generations will better understand what was destroyed by Nazi extermination policies, and provide lessons for modern political, hunger and war threats to human health. Shosha suffers from a lifelong debilitating disease that neither Singer nor subsequent commentaries ever name. The authors focus first on diagnosing the disease by consulting medical literature and experts. They then examine the value and pitfalls of this exercise and suggest that the lessons of understanding the disease historically, for teaching physicians how to recognise diseases rooted in war and poverty, and for enlightening all of us to the risks faced in human health by a world increasingly taking up arms and sliding towards fascism make diagnosing Shosha necessary and meaningful.

Abstract
The role of long noncoding RNAs (lncRNAs) in disease is incompletely understood, but their regulation of inflammation is increasingly appreciated. We addressed the extent of lncRNA involvement in inflammatory bowel disease (IBD) using biopsy-derived RNA-sequencing data from a large cohort of deeply phenotyped patients with IBD. Weighted gene correlation network analysis revealed gene modules of lncRNAs coexpressed with protein-coding genes enriched for biological pathways, correlated with epithelial and immune cell signatures, or correlated with distal colon expression. Correlation of modules with clinical features uncovered a module correlated with disease severity, with an enriched interferon response signature containing the hub lncRNA IRF1-AS1. Connecting genes to IBD-associated single nucleotide polymorphisms (SNPs) revealed an enrichment of SNP-adjacent lncRNAs in biologically relevant modules. Ulcerative colitis-specific SNPs were enriched in distal colon-related modules, suggesting that disease-specific mechanisms may result from altered lncRNA expression. The function of the IBD-associated SNP-adjacent lncRNA IRF1-AS1 was explored in human myeloid cells, and our results suggested IRF1-AS1 promoted optimal production of TNF-α, IL-6, and IL-23. A CRISPR/Cas9-mediated activation screen in THP-1 cells revealed several lncRNAs that modulated LPS-induced TNF-α responses. Overall, this study uncovered the expression patterns of lncRNAs in IBD that identify functional, disease-relevant lncRNAs.

Abstract
The gut and local esophageal microbiome progressively shift from healthy commensal bacteria to inflammation-linked pathogenic bacteria in patients with gastroesophageal reflux disease, Barrett's esophagus, and esophageal adenocarcinoma (EAC). However, mechanisms by which microbial communities and metabolites contribute to reflux-driven EAC remain incompletely understood and challenging to target. Herein, we utilized a rat reflux-induced EAC model to investigate targeting the gut microbiome-esophageal metabolome axis with cranberry proanthocyanidins (C-PAC) to inhibit EAC progression. Sprague-Dawley rats, with or without reflux induction, received water or C-PAC ad libitum (700 μg/rat/day) for 25 or 40 weeks. C-PAC exerted prebiotic activity abrogating reflux-induced dysbiosis and mitigating bile acid metabolism and transport, culminating in significant inhibition of EAC through TLR/NF-κB/TP53 signaling cascades. At the species level, C-PAC mitigated reflux-induced pathogenic bacteria (Streptococcus parasanguinis, Escherichia coli, and Proteus mirabilis). C-PAC specifically reversed reflux-induced bacterial, inflammatory, and immune-implicated proteins and genes, including Ccl4, Cd14, Crp, Cxcl1, Il6, Il1b, Lbp, Lcn2, Myd88, Nfkb1, Tlr2, and Tlr4, aligning with changes in human EAC progression, as confirmed through public databases. C-PAC is a safe, promising dietary constituent that may be utilized alone or potentially as an adjuvant to current therapies to prevent EAC progression through ameliorating reflux-induced dysbiosis, inflammation, and cellular damage.

Abstract
INTRODUCTION Heterogeneity in reported outcomes of infants with oesophageal atresia (OA) with or without tracheo-oesophageal fistula (TOF) prevents effective data pooling. Core outcome sets (COS) have been developed for many conditions to standardise outcome reporting, facilitate meta-analysis and improve the relevance of research for patients and families. Our aim is to develop an internationally-agreed, comprehensive COS for OA-TOF, relevant from birth through to transition and adulthood. METHODS AND ANALYSIS A long list of outcomes will be generated using (1) a systematic review of existing studies on OA-TOF and (2) qualitative research with children (patients), adults (patients) and families involving focus groups, semistructured interviews and self-reported outcome activity packs. A two-phase Delphi survey will then be completed by four key stakeholder groups: (1) patients (paediatric and adult); (2) families; (3) healthcare professionals; and (4) researchers. Phase I will include stakeholders individually rating the importance and relevance of each long-listed outcome using a 9-point Likert scale, with the option to suggest additional outcomes not already included. During phase II, stakeholders will review summarised results from phase I relative to their own initial score and then will be asked to rescore the outcome based on this information. Responses from phase II will be summarised using descriptive statistics and a predefined definition of consensus for inclusion or exclusion of outcomes. Following the Delphi process, stakeholder experts will be invited to review data at a consensus meeting and agree on a COS for OA-TOF. ETHICS AND DISSEMINATION Ethical approval was sought through the Health Research Authority via the Integrated Research Application System, registration no. 297026. However, approval was deemed not to be required, so study sponsorship and oversight were provided by Alder Hey Children's NHS Foundation Trust. The study has been prospectively registered with the COMET Initiative. The study will be published in an open access forum.

Abstract
INTRODUCTION Acute diverticulitis is a condition commonly seen in the emergency department (ED). Therefore, it is important for emergency medicine clinicians to be aware of the current evidence regarding the diagnosis and management of this disease. OBJECTIVE This paper evaluates key evidence-based updates concerning acute diverticulitis for the emergency clinician. DISCUSSION Diverticulitis is a complication of diverticulosis and most commonly affects the sigmoid and descending colon in Western countries. History and examination can suggest the diagnosis, with abdominal pain and tenderness in the left lower quadrant being the most common symptom and sign, respectively. Change in bowel habits and fever may also occur. Laboratory testing may demonstrate leukocytosis or an elevated C-reactive protein. Imaging options can include computed tomography (CT) of the abdomen and pelvis with intravenous contrast, magnetic resonance imaging (MRI), or ultrasound (US), though most classification systems for diverticulitis incorporate CT findings. While the majority of diverticulitis cases are uncomplicated, complications may affect up to 25% of patients. Treatment of complicated diverticulitis requires antibiotics and surgical consultation. Antibiotics are not required in select patients with uncomplicated diverticulitis. Appropriate patients for supportive care without antibiotics should be well-appearing, have pain adequately controlled, be able to tolerate oral intake, be able to follow up, have no complications, and have no immunocompromise or severe comorbidities. CONCLUSIONS An understanding of literature updates can improve the ED care of patients with acute diverticulitis.

Abstract
INTRODUCTION Immune-mediated inflammatory diseases including rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), non-radiographic axial spondylarthritis (nr-axSpA), atopic dermatitis (AD), ulcerative colitis (UC), and Crohn's disease (CD) pose a substantial burden on patients and their quality of life. Upadacitinib is an orally administered, selective, and reversible Janus kinase inhibitor indicated for seven conditions, but data on its safety versus other active treatments are limited. A systematic literature review of indirect and direct treatment comparisons of randomized controlled trials (RCTs) was conducted to assess the safety profile of upadacitinib. METHODS MEDLINE, Embase, and Cochrane Library databases were searched for indirect and direct treatment comparisons of RCTs that (1) included licensed upadacitinib dosages; (2) studied any of the seven conditions; (3) reported any adverse events (AEs), serious AEs (SAEs), AEs leading to discontinuation, major adverse cardiovascular event, venous thromboembolism, malignancies, infections or serious infections, and death; and (4) were published between January 2018 and August 2022. RESULTS A total of 25 studies were eligible for inclusion. SAEs, AEs leading to discontinuation, and any AEs were commonly studied. RA was the most studied condition, followed by AD and UC. Most studies (16/25, 64%) reported no statistically significant difference in the studied safety outcomes between upadacitinib and other active treatments (e.g., tumor necrosis factor blockers, interleukin receptor antagonists, integrin receptor antagonists, T cell co-stimulation modulator), or placebo (placebo ± methotrexate or topical corticosteroids). Other studies (9/25, 36%) reported mixed results of no statistically significant difference and either statistically higher (8/25, 32%) or lower rates (1/25, 4%) on upadacitinib. CONCLUSION Most studies suggested that upadacitinib has no statistically significant difference in the studied safety outcomes compared to active treatments or placebo in patients with RA, PsA, AS, AD, UC, and CD. A few studies reported higher rates, but findings were inconsistent with limited interpretation.

Abstract
Artificial Intelligence [AI] has been a trendy topic in recent years, with many developed medical applications. In gastrointestinal endoscopy, AI systems include computer-assisted detection [CADe] for lesion detection as bleedings and polyps and computer-assisted diagnosis [CADx] for optical biopsy and lesion characterization. The technology behind these systems is based on a computer algorithm that is trained for a specific function. This function could be to recognize or characterize target lesions such as colonic polyps. Moreover, AI systems can offer technical assistance to improve endoscopic performance as scope insertion guidance. Currently, we believe that such technologies still lack legal and regulatory validations as a large sector of doctors and patients have concerns. However, there is no doubt that these technologies will bring significant improvement in the endoscopic management of patients as well as save money and time.

Abstract
A man in his 40s presented to an emergency department after experiencing worsening abdominal pain for 2 days. Contrast-enhanced CT of the abdomen and pelvis revealed circumferential mural thickening and luminal narrowing of the distal ileum and upstream dilatation of the small intestine, indicating small intestine obstruction. This prompted emergency laparotomy, where two lesions in the distal ileum were identified as the source of his bowel obstruction and resected. Immunohistochemistry of the resected segment revealed a primary small intestine angiosarcoma acting positively for vascular markers ERG and CD31. A subsequent positron emission tomography (PET) scan revealed positive mediastinal metastatic lymphadenopathy without organ metastases.Following his surgery, the patient recovered well and was promptly referred to an oncology unit at a specialised health centre for further treatment. Primary small intestine angiosarcoma is a rare entity in which patients present with non-specific symptoms requiring prompt tissue diagnosis to facilitate multidisciplinary management.

Abstract
Purpose Various complications are associated with percutaneous endoscopic gastrostomy (PEG) procedures in children. The push technique is being increasingly used, but its complications are insufficiently characterized. We aimed to assess all complications related to PEG procedures and compare the safety of the pull and push techniques. Methods Retrospective review of consecutive pediatric patients who underwent PEG between 2002 and 2020. Results In total, 216 children underwent 217 PEG procedures. The push technique was used in 138 (64%) cases, and the pull technique in 79 (36%) cases. The median follow-up time was 6.1 (0.1-18.3) years. The complication rate was high (57%) and patients experienced complications years after the procedure. Overall, 51% and 67% of patients experienced complications in the push and pull groups, respectively. The rates of minor and major complications were higher in the pull group than in the push group (63% vs 48%, p=0.028; and 11% vs 6%, p=0.140, respectively). Reoperation was also more common in the pull group (17% vs 7%, p=0.020). Conclusions The overall complication rate of PEG procedures is high. Fortunately, most complications are mild and do not require reoperations. The increasing push technique appears to be safer than the traditional pull technique. Significant long-term morbidity is related to gastrostomies in children.

Abstract
BACKGROUNDThe tumor immune microenvironment can provide prognostic and therapeutic information. We aimed to develop noninvasive imaging biomarkers from computed tomography (CT) for comprehensive evaluation of immune context and investigate their associations with prognosis and immunotherapy response in gastric cancer (GC).METHODSThis study involved 2,600 patients with GC from 9 independent cohorts. We developed and validated 2 CT imaging biomarkers (lymphoid radiomics score [LRS] and myeloid radiomics score [MRS]) for evaluating the IHC-derived lymphoid and myeloid immune context respectively, and integrated them into a combined imaging biomarker [LRS/MRS: low(-) or high(+)] with 4 radiomics immune subtypes: 1 (-/-), 2 (+/-), 3 (-/+), and 4 (+/+). We further evaluated the imaging biomarkers' predictive values on prognosis and immunotherapy response.RESULTSThe developed imaging biomarkers (LRS and MRS) had a high accuracy in predicting lymphoid (AUC range: 0.765-0.773) and myeloid (AUC range: 0.736-0.750) immune context. Further, similar to the IHC-derived immune context, 2 imaging biomarkers (HR range: 0.240-0.761 for LRS; 1.301-4.012 for MRS) and the combined biomarker were independent predictors for disease-free and overall survival in the training and all validation cohorts (all P < 0.05). Additionally, patients with high LRS or low MRS may benefit more from immunotherapy (P < 0.001). Further, a highly heterogeneous outcome on objective response rate was observed in 4 imaging subtypes: 1 (-/-) with 27.3%, 2 (+/-) with 53.3%, 3 (-/+) with 10.2%, and 4 (+/+) with 30.0% (P < 0.0001).CONCLUSIONThe noninvasive imaging biomarkers could accurately evaluate the immune context and provide information regarding prognosis and immunotherapy for GC.

Abstract
Patients with cholangiocarcinoma have poor clinical outcomes due to late diagnoses, poor prognoses, and limited treatment strategies. To identify drug combinations for this disease, we have conducted a genome-wide CRISPR screen anchored on the bromodomain and extraterminal domain (BET) PROTAC degrader ARV825, from which we identified anticancer synergy when combined with genetic ablation of members of the mTOR pathway. This combination effect was validated using multiple pharmacological BET and mTOR inhibitors, accompanied by increased levels of apoptosis and cell cycle arrest. In a xenograft model, combined BET degradation and mTOR inhibition induced tumor regression. Mechanistically, the 2 inhibitor classes converged on H3K27ac-marked epigenetic suppression of the serine glycine one carbon (SGOC) metabolism pathway, including the key enzymes PHGDH and PSAT1. Knockdown of PSAT1 was sufficient to replicate synergy with single-agent inhibition of either BET or mTOR. Our results tie together epigenetic regulation, metabolism, and apoptosis induction as key therapeutic targets for further exploration in this underserved disease.

Abstract
Bile acids (BAs) affect the intestinal environment by ensuring barrier integrity, maintaining microbiota balance, regulating epithelium turnover, and modulating the immune system. As a master regulator of BA homeostasis, farnesoid X receptor (FXR) is severely compromised in patients with inflammatory bowel disease (IBD) and colitis-associated colorectal cancer (CAC). At the front line, gut macrophages react to the microbiota and metabolites that breach the epithelium. We aim to study the role of the BA/FXR axis in macrophages. This study demonstrates that inflammation-induced epithelial abnormalities compromised FXR signaling and altered BAs' profile in a mouse CAC model. Further, gut macrophage-intrinsic FXR sensed aberrant BAs, leading to pro-inflammatory cytokines' secretion, which promoted intestinal stem cell proliferation. Mechanistically, activation of FXR ameliorated intestinal inflammation and inhibited colitis-associated tumor growth, by regulating gut macrophages' recruitment, polarization, and crosstalk with Th17 cells. However, deletion of FXR in bone marrow or gut macrophages escalated the intestinal inflammation. In summary, our study reveals a distinctive regulatory role of FXR in gut macrophages, suggesting its potential as a therapeutic target for addressing IBD and CAC.

Abstract
Targeted metagenomic sequencing is an emerging strategy to survey disease-specific microbiome biomarkers for clinical diagnosis and prognosis. However, this approach often yields inconsistent or conflicting results owing to inadequate study power and sequencing bias. We introduce Taxa4Meta, a bioinformatics pipeline explicitly designed to compensate for technical and demographic bias. We designed and validated Taxa4Meta for accurate taxonomic profiling of 16S rRNA amplicon data acquired from different sequencing strategies. Taxa4Meta offers significant potential in identifying clinical dysbiotic features that can reliably predict human disease, validated comprehensively via reanalysis of individual patient 16S data sets. We leveraged the power of Taxa4Meta's pan-microbiome profiling to generate 16S-based classifiers that exhibited excellent utility for stratification of diarrheal patients with Clostridioides difficile infection, irritable bowel syndrome, or inflammatory bowel diseases, which represent common misdiagnoses and pose significant challenges for clinical management. We believe that Taxa4Meta represents a new "best practices" approach to individual microbiome surveys that can be used to define gut dysbiosis at a population-scale level.

Abstract
Circular RNAs (circRNAs) are highly expressed in the mammalian intestinal epithelium, but their functions remain largely unknown. Here, we identified the circRNA Cdr1as as a repressor of intestinal epithelial regeneration and defense. Cdr1as levels increased in mouse intestinal mucosa after colitis and septic stress, as well as in human intestinal mucosa from patients with inflammatory bowel disease and sepsis. Ablation of the Cdr1as locus from the mouse genome enhanced renewal of the intestinal mucosa, promoted injury-induced epithelial regeneration, and protected the mucosa against colitis. We found approximately 40 microRNAs, including miR-195, differentially expressed between intestinal mucosa of Cdr1as-knockout (Cdr1as-/-) versus littermate mice. Increasing the levels of Cdr1as inhibited intestinal epithelial repair after wounding in cultured cells and repressed growth of intestinal organoids cultured ex vivo, but this inhibition was abolished by miR-195 silencing. The reduction in miR-195 levels in the Cdr1as-/- intestinal epithelium was the result of reduced stability and processing of the precursor miR-195. These findings indicate that Cdr1as reduces proliferation and repair of the intestinal epithelium at least in part via interaction with miR-195 and highlight a role for induced Cdr1as in the pathogenesis of unhealed wounds and disrupted renewal of the intestinal mucosa.

Abstract
BACKGROUND Faecal microbiota transplantation (FMT) has mainly been studied in quantitative research to investigate effect rates. However, there is a lack of qualitative studies to explore patient perspectives. AIM To explore perceptions of quality of life in older patients with Clostridioides difficile infection (CDI) at least 1 week after receiving FMT. METHOD A qualitative study examining quality of life for patients treated with FMT. FINDINGS Patients with a permanent or transient treatment effect experienced an increase in quality of life in the physical, psychological and social domains. However, patients who did not respond to the treatment experienced negative impacts on their psychological, physical, and social domains. Although patients found the content unappealing, none had reservations about receiving the treatment. CONCLUSION This study highlights the importance of considering the psychological, social and physical wellbeing of patients when assessing the efficacy of FMT as a treatment option for patients with CDI. It further emphasises the importance of health professionals identifying patients' individual ways of handling the disease and everyday life to improve their quality of life.
