Abstract
BACKGROUND Data on the correlation between inflammatory mesenteric fat (i-fat), detected by intestinal ultrasound (IUS), and the prognosis of Crohn's disease (CD) remains limited. AIMS To investigate the impact of IUS-detected i-fat on long-term clinical outcomes. METHODS We retrospectively enrolled 171 active CD patients who initiated infliximab. Clinical remission (CR), mucosal healing (MH) and transmural healing (TH) were assessed at week-14 and 1 year. RESULTS Baseline i-fat was detected in 107 patients, while 64 without i-fat. At week-14 and 1 year, patients with i-fat showed lower rates of CR (61.7% vs. 87.5%; 62.3% vs. 86.7%), MH (20.6% vs. 46.9%; 38.6% vs. 65.0%) and TH (10.3% vs. 31.3%; 21.6% vs. 51.7%), compared to those without (all p<0.01). Multivariable analysis revealed that baseline i-fat was a negative predictor for CR (OR=0.212) and MH (OR=0.425) at week-14, and CR (OR=0.340) and TH (OR=0.364) at 1 year (all p<0.05). At week-14, 56 patients with baseline i-fat recovered to without i-fat. Patients with i-fat recovery had higher rates of CR (86.8% vs. 23.1%), MH (58.5% vs. 7.7%) and TH (34.0% vs. 2.6%) at 1 year than those with i-fat at week-14 (all p<0.001). CONCLUSION IUS-detected i-fat correlated poor long-term clinical outcomes in CD with infliximab.

Abstract
This systematic review evaluated the current status of AI-assisted colonoscopy to identify histologic remission and predict the clinical outcomes of patients with ulcerative colitis. The use of artificial intelligence (AI) has increased substantially across several medical fields, including gastrointestinal endoscopy. Evidence suggests that it may be helpful to predict histologic remission and relapse, which would be beneficial because current histological diagnosis is limited by the inconvenience of obtaining biopsies and the high cost and time-intensiveness of pathological diagnosis. MEDLINE and the Cochrane Central Register of Controlled Trials were searched for studies published between January 1, 2000, and October 31, 2023. Nine studies fulfilled the selection criteria and were included; five evaluated the prediction of histologic remission, two assessed the prediction of clinical outcomes, and two evaluated both. Seven were prospective observational or cohort studies, while two were retrospective observational studies. No randomized controlled trials were identified. AI-assisted colonoscopy demonstrated sensitivity between 65 %-98 % and specificity values of 80 %-97 % for identifying histologic remission. Furthermore, it was able to predict future relapse in patients with ulcerative colitis. However, several challenges and barriers still exist to its routine clinical application, which should be overcome before the true potential of AI-assisted colonoscopy can be fully realized.

Abstract
Advancements in murine modeling systems for ulcerative colitis have diversified our understanding of the pathophysiological factors involved in disease onset and progression. This has fueled the identification of molecular targets, resulting in a rapidly expanding therapeutic armamentarium. Subsequently, management strategies have evolved from symptomatic resolution to well-defined objective endpoints, including clinical remission, endoscopic remission and mucosal healing. While the incorporation of these assessment modalities has permitted targeted intervention in the context of a natural disease history and the prevention of complications, studies have consistently depicted discrepancies associated with ascertaining disease status through clinical and endoscopic measures. Current recommendations lack consideration of histological healing. The simultaneous achievement of clinical, endoscopic, and histologic remission has not been fully investigated. This has laid the groundwork for a novel therapeutic outcome termed disease clearance (DC). This article summarizes the concept of DC and its current evidence.

Abstract
OBJECTIVE(S) Our aim is to investigate the effects of the submucoperichondrial application of Platelet Rich Plasma (PRP) on nasal mucosal healing after septoplasty surgery. METHOD(S) This prospective randomized observational study was conducted between July 2019 and February 2021, with 40 patients aged 18-60 years who underwent closed the only septoplasty operation for similar septal deviations. Patient divided into two group; 21 patients were placed in PRP group to which PRP was applied on all mucosal surface and submucoperichondrial area of septum and 19 patients were placed in control group to which saline solution was applied on same regions. Nasal obstruction score, mucociliary clearance time, presence of nasal crusting, and bleeding time were evaluated on 5th, 10th, 15th day after surgery and compared between groups. RESULTS Intranasal crusting on day 10 was found to be lower in the PRP group (n:13 68.4 %) than control group (n:7 33.3 %) with a statistically significant difference (p = 0.028). The nasal obstruction score on day 10 and 15 were found to be lower in the PRP group (3,33 ± 2,75, 2,07 ± 2,20) (than the control group (5,44 ± 2,26, 3,37 ± 1,92) with a statistically significant difference (p = 0,003,p = 0,009). The mucociliary clearance rate was found to be higher and the bleeding time was found to be lower in the PRP group, but a statistically significant difference was not observed. CONCLUSIONS Application of submucoperichondrial PRP could have beneficial effects on nasal mucosal repair, nasal crusting, and congestion after septoplasty surgery.

Abstract
PURPOSE Behçet's disease (BD) is a complex disorder affecting multiple systems and organs, and gastrointestinal BD is poorly understood. We aimed to identify factors influencing the long-term outcomes of patients with gastrointestinal BD. METHODS Consecutive patients with gastrointestinal BD were analyzed retrospectively. Data on the following clinical characteristics were collected: sex, age at diagnosis, symptoms, endoscopic findings, medical treatments, and surgery. Mucosal healing and surgical rates at 1, 2, and 5 years were evaluated. Log-rank test and Cox proportional hazards regression models were used to evaluate the factors affecting long-term outcomes. FINDINGS Baseline data of 175 patients with gastrointestinal BD were included. The mean (SD) age at diagnosis was 38.3 (12.9) years. The typical clinical symptoms were oral ulcer (72.6%), abdominal pain (71.4%), and weight loss (41.1%). The most commonly involved location was the ileocecum; isolated oval ulcer was the most common ulcer type. Seventeen patients (9.7%) underwent 18 surgeries after inclusion. The cumulative surgical rates were 8.6% (n/N = 15/175), 8.6% (n/N = 15/175), and 9.1% (n/N = 16/175) in 1, 2, and 5 years, respectively. Data from 101 patients who underwent at least 2 endoscopies were included in the analysis for mucosal healing. Kaplan-Meier curve showed that the cumulative mucosal healing rates at 1, 2, and 5 years were 34.7% (n/N = 35/101), 41.6% (n/N = 42/101), and 61.4% (n/N = 62/101), respectively. We compared cumulative mucosal healing rates between 4 treatment groups, including 5-aminosalicylic acid (3% [n/N = 3/101]), mono-immunosuppressant (31.7% [n/N = 32/101]), combined therapy (36.6% [n/N = 37/101]), and escalation therapy (28.7% [n/N = 29/101]), and found that mono-immunosuppressant achieved earlier mucosal healing than combined therapy (P = 0.0008) and escalation therapy (P = 0.0008). The univariate analysis showed that moderate to severe disease activity (P = 0.013, P = 0.004), diameter of the maximal ulcer >4 cm (P = 0.002), and nonsimple esophageal involvement (P < 0.001) were risk factors, and number of ulcers between 2 and 5 was the protective factor of mucosal healing (P = 0.001). Multivariate regression analysis indicated that nonsimple esophageal involvement (P < 0.001) and the maximal ulcer >4 cm (P = 0.041) were independent risk factors of mucosal healing. IMPLICATIONS Most patients with gastrointestinal BD need long-term treatment to achieve mucosal healing. The location and size of ulcers have a significant impact on the mucosal healing of gastrointestinal BD.

Abstract
Colonic mucosal defect constitutes the major reason of recurrence and deterioration of ulcerative colitis (UC), and mucosal healing has become the therapeutic endpoint of UC. Unfortunately, specific promoter of mucosal healing is still absent. Our previous researches demonstrated that arctigenin could alleviate colitis symptoms in mice, but whether it has a positive impact on colonic mucosal healing remains unclear. This study explores whether and how arctigenin promotes mucosal healing. Orally administered arctigenin was shown to alleviate colitis in mice primarily by enhancing mucosal healing. In vitro, arctigenin was shown to promote the wound healing by accelerating colonic epithelial cell migration but not proliferation. Acceleration of the focal adhesion turnover, especially assembly, is crucial for arctigenin promoting the cell migration. Arctigenin was able to activate focal adhesion kinase (FAK) in colonic epithelial cells through directly binding with Tyr251 site of FAK, as evidenced by surface plasmon resonance assay and site-directed mutagenesis experiment. In the colonic epithelial cells of UC patients and colitis mice, FAK activation was significantly down-regulated compared with the controls. Arctigenin promoted colonic epithelial cell migration and mucosal healing in dextran sulphate sodium (DSS)-induced colitis mice dependent on activating FAK, as confirmed by combined use with FAK inhibitor. In summary, arctigenin can directly promote mucosal healing in colitis mice through facilitating focal adhesion turnover, especially assembly, and consequent migration of epithelial cells via targeting FAK. Arctigenin may be developed as a mucosal healing promoter, and FAK is a potential therapeutic target for UC and other mucosal defect-related diseases.

Abstract
INTRODUCTION Adherence to the Mediterranean diet (MD) was shown to be associated with decreased disease activity in adult patients with Crohn's disease (CD). Nevertheless, data on its association with fecal calprotectin (FC), particularly in children, remain limited. This study aimed to assess the association between adherence to the MD and FC as an indicator of mucosal healing in patients who are predominantly in remission while undergoing biological therapy. METHODS This was a cross-sectional study among children with CD. Adherence to MD was evaluated using both the KIDMED questionnaire and a food frequency questionnaire (FFQ). Israeli Mediterranean Diet Adherence Screener (I-MEDAS) score was calculated, and FC samples were obtained. RESULTS Of 103 eligible patients, 99 were included (mean age 14.3 ± 2.6 years; 38.4% females); 88% were in clinical remission, and 30% presented with elevated FC. The mean KIDMED score was higher among patients who had FC <200 μg/g compared to patients with FC >200 μg/g (5.48 ± 2.58 vs. 4.37 ± 2.47, respectively; p = 0.04). A moderate correlation between the KIDMED score and the I-MEDAS score was observed (r = 0.46; p = 0.001). In a multivariate regression analysis, adherence to MD was associated with decreased calprotectin levels, OR 0.75 [95% CI: 0.6-0.95], p = 0.019. Vegetable consumption was found to be inversely associated with elevated FC (0.9 portion/day [0.3-2.9] in FC >200 μg/g vs. 2.2 portions/day [0.87-3.82] in FC <200 μg/g; p = 0.049). CONCLUSIONS In children with CD who are mostly in clinical remission under biological therapy, high adherence to MD is associated with decreased FC levels. Encouraging vegetable consumption, especially during remission, may benefit these patients.

Abstract
BACKGROUND Mume Fructus (MF) is the fruit of Prunus mume Sieb. et Zucc, a plant of Rosaceae family. Previous studies demonstrated that MF was capable of ameliorating ulcerative colitis (UC) in mice, its action mechanism needs to be clarified. PURPOSE This study deciphered whether and how MF extract accelerates colonic mucosal healing, the therapeutic endpoint of UC. METHODS Biochemical, histopathological and qRT-PCR analyses were utilized to define the therapeutic efficacy of MF on dextran sulfate sodium (DSS)-induced colitis in mice. UHPLC-QTOF-MS/MS-based metabolomics technique was adopted to explore the changes of endogenous metabolites associated with UC and responses to MF intervention. qRT-PCR analysis was performed to confirm the molecular pathway in vivo. The effects of MF and lysophosphatidylcholine (LPC) on cell viability, wound healing, proliferation, and migration were examined through a series of in vitro experiments. Moreover, the effects of different subtypes of phospholipase A2 (PLA2) inhibitors on MF-treated colonic epithelial cells were detected by wound healing test and transwell assay. RESULTS Orally administered MF could alleviate colitis in mice mainly by accelerating the healing of colonic mucosa. Guided by an unbiased metabolomics screen, we identified LPC synthesis as a major modifying pathway in colitis mice after MF treatment. Notably, MF facilitated the synthesis of LPC by enhancing the expression of PLA2 in colitis mice. Mechanistically, MF and LPC accelerated wound closure by promoting cell migration. Moreover, the promotion of MF on wound healing and migration of colonic epithelial cells was blunted by a cytosolic phospholipase A2 (cPLA2) inhibitor. CONCLUSION MF can facilitate colonic mucosal healing of mice with colitis through cPLA2-mediated intestinal LPC synthesis, which may become a novel therapeutic agent of UC.

Abstract
Inflammatory bowel diseases (IBDs) treatments have shifted from small-molecular therapeutics to the oncoming biologics. The first-line biologics against the moderate-to-severe IBDs are mainly involved in antibodies against integrins, cytokines and cell adhesion molecules. Besides, other biologics including growth factors, antioxidative enzyme, anti-inflammatory peptides, nucleic acids, stem cells and probiotics have also been explored at preclinical or clinical studies. Biologics with variety of origins have their unique potentials in attenuating immune inflammation or gut mucosa healing. Great advances in use of biologics for IBDs treatments have been archived in recent years. But delivering issues for biologic have also been confronted due to their liable nature. In this review, we will focus on biologics for IBDs treatments in the recent publications; summarize the current landscapes of biologics and their promise to control disease progress. Alternatively, the confronted challenges for delivering biologics will also be analyzed. To combat these drawbacks, some new delivering strategies are provided: firstly, designing the functional materials with high affinity toward biologics; secondly, the delivering vehicle systems to encapsulate the liable biologics; thirdly, the topical adhering delivery systems as enema. To our knowledge, this review is the first study to summarize the updated usage of the oncoming biologics for IBDs, their confronted challenges in term of delivery and the potential combating strategies.

Abstract
Hydrogels are a class of biocompatible materials with versatile functions that have been increasing explored for the localized treatment of ulcerative colitis (UC), but various mechanical stimuli may cause premature hydrogel breakage and detachment, impeding their further clinical translation. Here we report a multifunctional mechanically-resilient self-healing hydrogel for effective UC treatment, which is synthesized through the host-guest interaction between dopamine/β-cyclodextrin-modified hyaluronic acid (HA-CD-DA) and amantadine-modified carboxymethyl chitosan (CMCS-AD). The excessive β-CD cavities allow the incorporation of dexamethasone (DEX), while the porous hydrogel network potentiates the encapsulation of basic fibroblast growth factor (bFGF) and L-alanyl-l-glutamine (ALG). DA moieties in HA components allow firm adhesion of the hydrogel to the ulcerative lesions after in-situ implantation, while the reversible host-guest interaction between CD and AD could enhance the persistence of hydrogel. The hydrogel demonstrated favorable biocompatibility and could continuously release DEX to induce M1-to-M2 repolarization of mucosal macrophages through inhibiting the toll-like receptor 4 (TLR4)-nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) axis. Furthermore, the co-delivered bFGF and ALG facilitates the regeneration of ulcerative mucosa and restore its barrier functions to ameliorate UC symptoms. The mechanically resilient hydrogel offers an integrative approach for UC therapy in the clinics.

Abstract
INTRODUCTION Discordance between gastrointestinal (GI) symptoms and endoscopic inflammation in patients with ulcerative colitis (UC) is known. However, the correlations between symptoms and endoscopic and histologic (endo-histologic) mucosal healing and remains unknown. METHODS We performed a secondary analysis of prospectively collected clinical, endoscopic, and histologic data on 254 colonoscopies from 179 unique adults at a tertiary referral center from 2014 to 2021. Spearman's rank was used to assess the correlation between patient reported outcomes and objective assessments of disease activity, as measured by validated instruments: Two-item patient-reported outcome measure (PRO-2) for stool frequency and rectal bleeding, the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) for endoscopic inflammation, and the Geboes score for histologic inflammation. The predictive value of objective assessments of inflammation and clinical symptoms was described using sensitivity, specificity, and positive/negative predictive value. RESULTS One-quarter (28%, 72/254) of cases were in endo-histologic remission; of these, 25% (18/72) report GI symptoms (22% diarrhea; 6% rectal bleeding). Endo-histologically active disease had higher sensitivity (95% rectal bleeding; 87% diarrhea) and negative predictive value (94% rectal bleeding, 78% diarrhea) for clinically active disease compared to active disease on endoscopic (77%) or histologic assessment only (80%). The specificity of endo/histologic inflammation for GI symptoms was < 65%. PRO-2 was positively correlated with endoscopic disease activity (Spearman's rank 0.57, 95% CI 0.54-0.60, p < 0.0001) and histologic disease activity (Spearman's rank 0.49, 0.45-0.53, p < 0.0001). CONCLUSION One-quarter of patients with ulcerative colitis in endo-histologic (deep) remission have gastrointestinal symptoms, more commonly with diarrhea than rectal bleeding. Endo-histologic inflammation has high sensitivity (≥ 87%) for diarrhea/rectal bleeding.

Abstract
BACKGROUND At present, the most studied inflammatory markers of Crohn's disease (CD) are C-reactive protein, but CD cannot be predicted by a single index. In recent years, studies have found that the combined application of serum markers can be more accurate for prediction, and platelet/serum albumin (PLT/ALB) and C-reactive protein/serum albumin (CRP/ALB) ratios have high specificity in evaluating inflammatory activity.
AIM To explore the value of serological platelet/albumin and C-reactive protein/albumin ratios in evaluating mucosal healing and disease recurrence in patients with CD.
METHODS Eighty-five patients with CD treated at Xinzhou District People's Hospital from April 2019 to April 2021 were selected. According to the clinical and endoscopic healing criteria, the patients were divided into either a mucosal healing group or a mucosal non-healing group. The general data, serum ALB, PLT, and CRP levels, and PLT/ALB and CRP/ALB ratios were recorded before and after treatment. The correlation between serum indexes and SES-CD score was analyzed to evaluate their value in assessing mucosal healing. The patients were divided into a recurrent group and a non-recurrent group according to whether they relapsed. The value of serum indexes in predicting disease recurrence was assessed.
RESULTS After 6 mo of treatment, the level of ALB in the mucosal healing group (n = 44) was significantly higher than that in the mucosal non-healing group (n = 41), while the levels of PLT, CRP, PLT/ALB ratio, and CRP/ALB ratio significantly decreased (P < 0.05). Serum ALB, PLT, CRP, PLT/ALB ratio, and CRP/ALB ratio were significantly correlated with SES-CD score. The AUC values of ALB, PLT, CRP, CRP/ALB ratio, and PLT/ALB ratio in assessing mucosal healing were 0.712, 0.662, 0.774, 0.776, and 0.719, respectively (all AUC values > 0.5). After treatment, ALB in the recurrent group was significantly lower than that in the non-recurrent group, while the levels of PLT, CRP, PLT/ALB ratio, and CRP/ALB ratio were significantly higher in the recurrent group (P < 0.05). The AUC values of ALB, PLT, CRP, CRP/ALB ratio, and PLT/ALB ratio for predicting disease recurrence were 0.641, 0.628, 0.643, 0.652, and 0.651, respectively (all AUC values > 0.5).
CONCLUSION PLT/ALB and CRP/ALB ratios have high clinical value in evaluating mucosal healing and disease recurrence in patients with CD.

Abstract
Mucosal healing is essential for treating ulcerative colitis (UC), which results from imbalanced macrophage polarization and dysregulated inflammatory responses. However, the mechanisms of cellular communication and signal transduction that regulate mucosal healing among macrophage subtypes require further investigation. We use bulk and single-cell RNA sequencing analysis to reveal that macrophage subtypes vary in different UC states. At the same time, chemokine and angiogenesis signaling is strongly associated with M2 macrophage's infiltrated proportion. To get more insight into subtypes of macrophages in mucosal healing, we divided macrophages into M1, M2b, and M2d macrophages. Based on the differentially expressed genes (DEGs) between M2d and M1 macrophages, KEGG and GO analysis highlights M2d macrophages' ability to alleviate inflammation and promote epithelial healing. Trajectory analysis revealed opposite differentiation of macrophage subsets between UC and healthy groups, with M1 and M2d macrophages coexisting in the same differentiation branch under UC conditions. Along the pseudotime axis, CCL3 and VEGFA expression increased in UC, while IL10RA remained stable in UC but increased in healthy controls. CellChat identified CCL3-CCR1 has strong communication between M1 and M2d macrophages, while the IL10 signaling pathway is activated explicitly in M2d macrophages to mitigate inflammation and promote epithelial healing. We also speculate that high levels of VEGFA activate endothelial cells expressing VEGFR and worsen inflammation. To conclude, we suggested IL10 and VEGF signaling in M2d macrophages as potential therapeutic targets for mucosal healing. However, it is necessary to establish reliable methods for isolating and purifying M2d macrophages before these targets can be effectively utilized.

Abstract
BACKGROUND Glucagon-like peptide-2 (GLP-2) enhances intestinal repair and attenuates inflammation in preclinical inflammatory bowel disease (IBD) models, making GLP-2 analogues attractive candidates for IBD therapy. Glepaglutide is a long-acting GLP-2 receptor agonist in clinical development for treatment of short bowel syndrome. Here, we investigated if glepaglutide is therapeutically beneficial in rats with small intestinal inflammation. METHODS Small intestinal inflammation was induced with indomethacin in naive Wistar rats, followed by glepaglutide administration at different disease stages. Glepaglutide was administered in co-treatment and post-treatment regimens. Small intestinal length and concentrations of inflammatory markers α-1-acid glycoprotein and myeloperoxidase were used to assess anti-inflammatory effects. Small intestinal mass was evaluated to determine intestinotrophic effects. RESULTS Glepaglutide co- and post-treatment significantly reduced severity of small intestinal inflammation, evidenced by reversed small intestinal shortening and decreased α-1-acid glycoprotein and/or myeloperoxidase concentration(s). Co- and post-treatment with glepaglutide also significantly increased small intestinal mass, indicating intestinal regenerative effects. Similar effects were observed in naive rats after glepaglutide treatment. CONCLUSION Glepaglutide has anti-inflammatory and intestinotrophic effects without the need for pre-treatment in a rat model of small intestinal inflammation. Thus, glepaglutide is of potential clinical interest for patients with IBD.

Abstract
Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease with serious mucosal inflammation mainly in the colon and rectum. Currently, there is no effective therapeutics for UC. Indoximod (IND) is a water-insoluble inhibitor for indolamine 2, 3-dioxygenase (IDO) and has been mainly reported in cancer therapy. Here, we prepared orally administrated IND nanoparticles (IND-NPs) for UC treatment and investigated their functions and mechanisms in cellular and animal inflammatory models. Confocal imaging demonstrated that IND-NPs maintained the expression level of ZO-1, Occludin and E-cadherin, thereby stabilizing of intercellular junction in Caco-2 cells. It was found that IND-NPs could lower the ROS level and increase mitochondrial membrane potential as well as ATP level, indicating that IND-NPs could restore DSS-induced mitochondrial dysfunction. In the mice model with DSS-induced colitis, IND-NPs were found to alleviate UC-associated symptoms, inhibit inflammatory response, and improve the integrity of epithelial barrier. The untargeted metabolomics analysis validated that IND-NPs also contributed to regulate the metabolite levels to normal. As an agonist of aryl hydrocarbon receptor (AhR), IND-NPs might repair mucosa via the AhR pathway. These findings demonstrated that IND-NPs prominently ameliorated DSS-induced colonic injury and inflammation and preserved intestinal barrier integrity, showing a promising potential in UC treatment.

Abstract
Mucosal healing (MH) is vital in maintaining homeostasis within the gut and protecting against injury and infections. Multiple factors and signaling pathways contribute in a dynamic and coordinated manner to maintain intestinal homeostasis and mucosal regeneration/repair. However, when intestinal homeostasis becomes chronically disturbed and an inflammatory immune response is constitutively active due to impairment of the intestinal epithelial barrier autoimmune disease results, particularly inflammatory bowel disease (IBD). Many proteins and signaling pathways become dysregulated or impaired during these pathological conditions, with the mechanisms of regulation just beginning to be understood. Consequently, there remains a relative lack of broadly effective therapeutics that can restore MH due to the complexity of both the disease and healing processes, so tissue damage in the gastrointestinal tract of patients, even those in clinical remission, persists. With increased understanding of the molecular mechanisms of IBD and MH, tissue damage from autoimmune disease may in the future be ameliorated by developing therapeutics that enhance the body’s own healing response. In this review, we introduce the concept of mucosal healing and its relevance in IBD as well as discuss the mechanisms of IBD and potential strategies for altering these processes and inducing MH.

Abstract
BACKGROUND Mucosal healing (MH) is recognized as a therapeutic target in ulcerative colitis (UC) because of evidence that it is associated with favorable clinical outcomes. Current endoscopic assessment of MH by conventional white-light endoscopy is subject to several important clinical issues including the subjective nature of assessment, intra- and interobserver variability, and persistent microscopic inflammation, even in mucosa it was observed as quiescent on conventional endoscopy. SUMMARY Advances in image-enhancement technologies enable the provision of high-contrast images that emphasize the mucosal structures, blood vessel patterns, and color tones of the intestinal mucosa, and recently, several image-enhanced endoscopy (IEE) techniques have become available for the assessment of MH in UC. Narrow-band imaging and dual-red imaging facilitate visualization of mucosal vascular structures, which is useful for detecting minor inflammation and predicting relapse because of the capturing of information on incomplete vascular regeneration in patients with UC. Linked-color imaging (LCI) is optimized to emphasize the redness of the mucosa and blood vessels, and is superior for depicting subtle color changes arising from mucosal inflammation. LCI could possibly be used to stratify UC patients with MH on conventional endoscopy. Autofluorescence imaging and i-scan can also depict subtle histological changes underlying the healing of mucosa in UC, revealing them as simple color changes. KEY MESSAGES Accumulating evidence suggests that IEE techniques could overcome current unmet needs in the endoscopic assessment of MH in UC and contribute to improving therapy based on treat-to-target strategies.

Abstract
Aim The present study aims to determine the rate of mucosal recovery and predictors of persistent mucosal damage after gluten free diet (GFD). Background Celiac disease (CD) is a complex multi-systemic autoimmune disease triggered by exposure to dietary gluten in genetically predisposed individuals. There is still little evidence on the best method for assessing GFD adherence and mucosal recovery during treatment. Methods The retrospective study included only adult patients (age≥18 years old), with biopsy-proven CD evaluated at a tertiary referral centre between 2016 and 2021. We performed a logistic regression analysis to identify factors associated with partial mucosal recovery (MR) after GFD. We included in the multivariate analysis parameters available at the time of CD diagnosis. Results A total of 102 patients were enrolled, two thirds were females, median age of 39 years (yrs). The initial biopsy analysis showed different stages of villous atrophy (VA) in 79 (77.4%) cases, while in 23(22.5%) cases showed mild enteropathy (Marsh 1, 2). After at least 12 months of GFD, 26 (25.5%) patients had persistent VA despite good or excellent adherence to GFD. Younger patients (< 35yrs), who showed severe mucosal damage (Marsh 3c lesions) and who had increased anti-gliadin antibody (AGA) levels were at risk for failure to obtain mucosal recovery (MR). Logistic regression analysis demonstrated that complete mucosal atrophy (P=0.007) and high AGA antibody levels (cutoff 129 U/ml, P=0.001) were independent risk factors for lack of mucosal improvement after at least 12 months of GFD. Interestingly, genotype, tTG-IgA antibody levels, or duration of GFD levels did not influence the occurrence of MR. Conclusion Although AGA seropositivity has lost much of their diagnostic significance in recent years due to the introduction of the more sensitive and specific antibody tests, our study reported that patients aged < 35 yrs, who showed severe mucosal damage (Marsh 3c lesions) and who had increased AGA antibody levels at diagnosis were at risk for failure to obtain MR. The elevated AGA levels at diagnosis could be used as a prognostic tool for assessing MR.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) injure the proximal and distal gut by different mechanisms. While many drugs reduce gastrointestinal injury, no drug directly stimulates mucosal wound healing. Focal adhesion kinase (FAK), a non-receptor tyrosine kinase, induces epithelial sheet migration. We synthesized and evaluated a water-soluble FAK-activating small molecule, M64HCl, with drug-like properties. Monolayer wound closure and Western blots measured migration and FAK phosphorylation in Caco-2 cells, in vitro kinase assays established FAK activation, and pharmacologic tests assessed drug-like properties. 30 mg/kg/day M64HCl was administered in two murine small intestine injury models for 4 days. M64HCl (0.1-1000 nM) dose-dependently increased Caco-2 FAK-Tyr 397 phosphorylation, without activating Pyk2 and accelerated Caco-2 monolayer wound closure. M64HCl dose-responsively activates the FAK kinase domain vs. the non-salt M64, increasing the Vmax of ATP-binding. Pharmacologic tests suggested M64HCl has drug-like properties and is enterally absorbed. M64HCl 25 mg/kg/day continuous infusion promoted healing of ischemic jejunal ulcers and indomethacin-induced small intestinal injury in C57Bl/6 mice. M64HCl-treated mice exhibited smaller ulcers 4 days after ischemic ulcer induction or indomethacin injury. Renal histology and plasma creatinine were normal. Mild hepatic inflammatory changes and ALT elevation were similar among M64HCl-treated mice and controls. M64HCl was concentrated in kidney and gastrointestinal mucosa and functional nephrectomy studies suggested predominantly urinary excretion. Little toxicity was observed in vitro or in single-dose mouse toxicity studies until >1000x higher than effective concentrations. M64HCl, a water-soluble FAK activator, promotes epithelial restitution and intestinal mucosal healing and may be useful to treat gut mucosal injury.

Abstract
BACKGROUND Although expression of interleukin (IL)-34 is upregulated in active ulcerative colitis (UC), the molecular function and underlying mechanism are largely unclear.
AIM To investigate the function of IL-34 in acute colitis, in a wound healing model and in colitis-associated cancer in IL-34-deficient mice.
METHODS Colitis was induced by administration of dextran sodium sulfate (DSS), and carcinogenesis was induced by azoxymethane (AOM). Whether the impact of IL-34 on colitis was dependent on macrophages was validated by depletion of macrophages in a murine model. The association between IL-34 expression and epithelial proliferation was studied in patients with active UC.
RESULTS IL-34 deficiency aggravated murine colitis in acute colitis and in wound healing phase. The effect of IL-34 on experimental colitis was not dependent on macrophage differentiation and polarization. IL-34-deficient mice developed more tumors than wild-type mice following administration of AOM and DSS. No significant difference was shown in degree of cellular differentiation in tumors between wild-type and IL-34-deficient mice. IL-34 was dramatically increased in the active UC patients as previously reported. More importantly, expression of IL-34 was positively correlated with epithelial cell proliferation in patients with UC.
CONCLUSION IL-34 deficiency exacerbates colonic inflammation and accelerates colitis-associated carcinogenesis in mice. It might be served as a potential therapeutic target in UC.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Inflammatory bowel disease (IBD) is pathologically characterized by an immune response accommodative insufficiency and dysbiosis accompanied by persistent epithelial barrier dysfunction, and is divided into ulcerative colitis (UC) and Crohn's disease (CD). Its progression increases the susceptibility to colitis-associated cancer (CAC), as well as other complications. The Xiao-Jian-Zhong (XJZ) formula has a historical application in the clinic to combat gastrointestinal disorders. AIM OF THE STUDY The investigation aimed to explore the molecular and cellular mechanisms of XJZ. MATERIALS AND METHODS Dextran sodium sulfate (DSS) was diluted in drinking water and given to mice for a week to establish murine models of experimental colitis, and the XJZ solution was administered for two weeks. Network pharmacology analysis and weighted gene co-expression network analysis (WGCNA) were utilized to predict the therapeutic role of XJZ against UC and CAC. 16S rRNA sequencing and untargeted metabolomics were conducted utilizing murine feces to examine the changes in the microbiome profile. Biochemical experiments were conducted to confirm the predicted functions. RESULTS XJZ treatment markedly attenuated DSS-induced experimental colitis progression, and the targets were enriched in inflammation, infection, and tumorigenesis, predicted by network pharmacology analysis. Based on The Cancer Genome Atlas (TCGA) database, the XJZ-targets were related to the survival probability in patients with colorectal cancer, underlying a potential therapeutic value in cancer intervention. Moreover, the XJZ therapy successfully rescued the decreased richness and diversity of microbiota, suppressed the potentially pathogenic phenotype of the gut microorganisms, and reversed the declined linoleic acid metabolism and increased cytochrome P450 activity in murine colitis models. Our in-vitro experiments confirmed that the XJZ treatment suppressed Caspase1-dependent pyroptosis and increased peroxisome proliferators-activated receptor-γ(PPAR-γ) expression in the colon, facilitated the alternative activation of macrophages (Mφs), inhibited tumor necrosis factor-α (TNFα)-induced reactive oxygen species (ROS) level in intestinal organoids (IOs), thereby favoring the mucosal healing. CONCLUSION The XJZ formula is efficacious for colitis by a prompt resolution of inflammation and dysbiosis, and by re-establishing a microbiome profile that favors re-epithelization, and prevents carcinogenesis.

Abstract
PURPOSE Fecal calprotectin (FC) levels can reflect the level of intestinal inflammation. Crohn's disease (CD), which affects the small bowel, has not been linked to FC levels. We determined if FC levels and endoscopic activity were related by performing double-balloon endoscopy (DBE). METHODS Herein, patients with small bowel CD diagnosed by DBE between January 2020 and January 2022 were prospectively observed. Feces and blood samples of patients were collected before performing DBE and checked for the levels of FC and serological biomarkers. The endoscopic activity and mucosal healing (MH) were evaluated using the partial simple endoscopic score (pSES-CD). RESULTS In all 254 CD patients, FC levels were correlated with pSES-CD (r = 0.775, P < 0.001). Even in patients with isolated small bowel CD, FC levels were strongly correlated with pSES-CD (r = 0.753, P < 0.001). In all patients, FC as an endoscopic remission indicator was found to have an area under the curve (AUC) of 0.872, with a cut-off value of 156.09 µg/g. In patients with isolated small bowel CD, FC yielded a high AUC of 0.865 for predicting endoscopic remission, with a cut-off value of 211.48 µg/g, sensitivity of 73.95%, and specificity of 91.30%. FC was optimally cut-off at 76.99 µg/g to predict MH in accordance with the AUC of 0.877. CONCLUSIONS Using DBE findings, FC was found to be significantly correlated with pSES-CD. Even in isolated small bowel CD, FC may be a more reliable marker of accurately predicting endoscopic remission and MH.

Abstract
BACKGROUND Optimal management of patients with ulcerative colitis (UC) requires the accurate, objective assessment of disease activity. AIMS We aimed to determine how strong patient-reported outcomes, clinical scores and symptoms correlate with endoscopy and biomarkers for assessment of disease activity in patients with UC. METHODS Consecutive patients with UC followed at the McGill University IBD Center and referred for endoscopy (surveillance or flare) were included prospectively between September 2018 and August 2020. Patient-reported outcome (PRO2), partial Mayo, Simple Clinical Colitis Activity Index (SCCAI), Mayo endoscopic subscore (MES) and Baron and Ulcerative Colitis Endoscopic Index of Severity (UCEIS) scores were calculated. C-reactive protein (CRP) and fecal calprotectin (FCAL) were collected. RESULTS A total of 171 patients with UC [age: 49(IQR:38-61) years, female: 46.2%, 57.3% extensive disease, 42.7% on biologicals] were included prospectively. Rectal bleeding (RBS), stool frequency (SF) subscore of 0, or total PRO2 remission (RBS0 and SF ≤ 1), partial Mayo (≤ 2) and SCCAI (≤ 2.5) remission were similarly associated with mucosal healing defined by MES (0 or ≤ 1), Baron (0 or ≤ 1) or UCEIS (≤ 3) scores in ROC analysis (AUC:0.93-0.72). There was a moderate-to-strong agreement between MES Baron and UCEIS (K = 0.91-0.41). A UCEIS of ≤ 3 was identified as the best cutoff to clinical or endoscopic remission. Agreement between CRP and clinical remission or endoscopic healing (MES/Baron) was poor (K ~ 0.2), while agreement between FCAL and RBS-PRO2 or MES/Baron/UCEIS was moderate to strong (K = 0.44-0.70). CONCLUSIONS Agreement between RBS, SF, PRO2, partial Mayo and SCCAI in predicting endoscopic healing was moderate to strong, while no clinically meaningful difference was found in accuracy across the scores and definitions. FCAL, but not CRP, was associated to clinical and endoscopic remission.

Abstract
INTRODUCTION Ulcerative colitis (UC) is a chronic disease characterized by diffuse inflammation of the mucosa of colon and rectum. Interferon regulatory factor 4 (IRF4) mediates macrophage anti-inflammatory phenotype (alternatively activated macrophages [M2]). This study aimed to investigate the mechanism of IRF4 in lipopolysaccharide (LPS)-induced colonic mucosal epithelial cell proliferation via the regulation of macrophage polarization. METHODS Human bone marrow-derived macrophages were subjected to interleukin 4 (IL-4) induction. M2 macrophages were identified using flow cytometry and quantitative real-time polymerase chain reaction (qRT-PCR). IRF4 expression in M2 macrophages was detected using Western blot and qRT-PCR. IRF4 expression was silenced in M2 macrophages. IL-10 mRNA expression and protein level were detected using qRT-PCR and Western blot. The binding relation between IRF4 and IL-10 was verified using dual-luciferase and chromatin immunoprecipitation assays. Macrophages under different treatments were cocultured with LPS-induced human colonic mucosal epithelial cells. The levels of inflammatory factors (TNF-α, IL-6, and IL-1β) were detected using enzyme-linked immunosorbent assay. The proliferation of inflammatory cells was measured using Cell Counting Kit-8 assay, and the healing of inflammatory cells was detected using wound healing assay. RESULTS M2 macrophages alleviated LPS-induced inflammatory responses. IRF4 bound to IL-10 and promoted IL-10 expression. Inhibition of IRF4 reduced IL-10 expression and attenuated the alleviating effect of M2 macrophages on inflammatory responses. Inhibition of IRF4 combined with IL-10 overexpression enhanced the promoting effect of M2 macrophages on inflammatory healing. CONCLUSION IRF4 promoted colonic mucosal epithelial cell proliferation by increasing IL-10 expression and regulating macrophage polarization to M2 phenotype, which might be related to UC mucosal healing.

Abstract
Ulcerative colitis (US) is a chronic disease of unknown etiology. It is incurable and its clinical course is intermittent, characterized by periods of remission and relapse. The prevalence and incidence of the disease has been increasing worldwide. The update presented herein includes the participation of healthcare professionals, decision-makers, and a representative of the patients, all of whom declared their conflicts of interest. Answerable clinical questions were formulated, and the outcomes were graded. The information search was conducted on the Medline/PubMed, Embase, Epistemonikos, and LILACS databases, and covered grey literature sources, as well. The search was updated on November 30, 2020, with no restrictions regarding date or language. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) classification system was implemented to establish the strength of the recommendation and quality of evidence. A formal consensus was developed, based on the RAND/UCLA methodology and the document was peer reviewed. The short version of the Clinical Practice Guidelines for the Treatment of Ulcerative Colitis in the Adult Population is presented herein, together with the supporting evidence and respective recommendations. In mild-to-moderate UC, budesonide MMX is an option when treatment with 5-ASA fails, and before using systemic steroids. In moderate-to-severe UC, infliximab, adalimumab, vedolizumab, ustekinumab, and tofacitinib can be used as first-line therapy. If there is anti-TNF therapy failure, ustekinumab and tofacitinib provide the best results. In patients with antibiotic-refractory pouchitis, anti-TNFs are the treatment of choice.

Abstract
Endoscopy is vital for diagnosing, assessing treatment response, and monitoring surveillance in patients with inflammatory bowel disease (IBD). With the growing importance of mucosal healing as a treatment target, the assessment of disease activity by endoscopy has been accepted as the standard of care for IBD. There are many endoscopic activity indices for facilitating standardized reporting of the gastrointestinal mucosal appearance in IBD, and each index has its strengths and weaknesses. Although most endoscopic indices do not have a clear-cut validated definition, endoscopic remission or mucosal healing is associated with favorable outcomes, such as a decreased risk of relapse. Therefore, experts suggest utilizing endoscopic indices for monitoring disease activity and optimizing treatment to achieve remission. However, the regular monitoring of endoscopic activity is limited in practice owing to several factors, such as the complexity of the procedure, time consumption, inter-observer variability, and lack of a clear-cut, validated definition of endoscopic response or remission. Although experts have recently suggested consensus-based definitions, further studies are needed to define the values that can predict long-term outcomes.

Abstract
BACKGROUND Mucosal healing, the result of endoscopic remission, is associated with prolonged clinical remission and delayed deterioration of Crohn's disease, which is significant and accompanied by reduced hospitalizations and surgeries. Currently, the relationship between ultrasonic parameters and mucosal healing remains controversial. To establish an ultrasonic regression model to evaluate mucosal healing, we conducted this preliminary study using multiple parameters from B-mode ultrasonography, colour Doppler flow imaging and shear wave elastography systematically. METHODS This study consisted of two single-centre investigations based on development and validation populations who received endoscopies (as the gold standard) and ultrasound. The involved bowel segments were divided into mucosal healing (MH) and nonmucosal healing (NMH) groups according to endoscopic results. Eight ultrasonic parameters were observed, including bowel wall thickness (BWT), mesenteric fat thickness (MFT), median modulus of elasticity (Emean), average shear wave velocity (SWV), Limberg scoring (LG), bowel wall stratification (BWS), ascites (AS) and lymph node enlargement (LN). We developed an ultrasonic regression model in the development phase to evaluate segmental mucosal healing and undertook prospective validation of this model. RESULTS A total of 124 patients with 380 involved bowel segments from the development and validation cohorts were evaluated. Eight ultrasonic parameters were significantly different between the two groups (P<0.05) in the development phase. Four significant parameters with better AUC performance were selected to establish an ultrasonic regression model to predict mucosal healing. The AUCs of this ultrasonic model were 0.975 and 0.942 in the development and validation cohorts, respectively. CONCLUSION The multimodal ultrasonic model has the potential to evaluate segmental mucosal healing in Crohn's disease.

Abstract
BACKGROUND Assessment of mucosal healing is important for the management of patients with inflammatory bowel disease (IBD), but endoscopy can miss microscopic disease areas that may relapse. Histological assessment is informative, but no single scoring system is widely adopted. We previously proposed an eight-item histological scheme for the easy, fast reporting of disease activity in the intestine. The aim of the present study was to evaluate the performance of our Simplified Histologic Mucosal Healing Scheme (SHMHS). METHODS Between April and May 2021 pathologists and gastroenterologists in Italy were invited to contribute to this multicenter study by providing data on single endoscopic-histological examinations for their IBD patients undergoing treatment. Disease activity was expressed using SHMHS (maximum score, 8) and either Simple Endoscopic Score for Crohn's Disease (categorized into grades 0-3) or Mayo Endoscopic Subscore (range 0-3). RESULTS Thirty hospitals provided data on 597 patients (291 Crohn's disease; 306 ulcerative colitis). The mean SHMHS score was 2.96 (SD = 2.42) and 66.8% of cases had active disease (score ≥ 2). The mean endoscopic score was 1.23 (SD = 1.05), with 67.8% having active disease (score ≥ 1). Histologic and endoscopic scores correlated (Spearman's ρ = 0.76), and scores for individual SHMHS items associated directly with endoscopic scores (chi-square p < 0.001, all comparisons). Between IBD types, scores for SHMHS items reflected differences in presentation, with cryptitis more common and erosions/ulcerations less common in Crohn's disease, and the distal colon more affected in ulcerative colitis. CONCLUSIONS SHMHS captures the main histological features of IBD. Routine adoption may simplify pathologist workload while ensuring accurate reporting for clinical decision making.

Abstract
PURPOSE Mucosal healing (MH) has become the treatment goal of patients with Crohn's disease (CD). This study aims to develop a noninvasive and reliable clinical tool for individual evaluation of mucosal healing in patients with Crohn's disease. METHODS A multicenter retrospective cohort was established. Clinical and serological variables were collected. Separate risk factors were incorporated into a binary logistic regression model. A primary model and a simple model were established, respectively. The model performance was evaluated with C-index, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy. Internal validation was performed in patients with small intestinal lesions. RESULTS A total of 348 consecutive patients diagnosed with CD who underwent endoscopic examination and review after treatment from January 2010 to June 2021 were composed in the derivation cohort, and 112 patients with small intestinal lesions were included in the validation cohort. The following variables were independently associated with the MH and were subsequently included into the primary prediction model: PLR (platelet to lymphocyte ratio), CAR (C-reactive protein to albumin ratio), ESR (erythrocyte sedimentation rate), HBI (Harvey-Bradshaw Index) score and infliximab treatment. The simple model only included factors of PLR, CAR and ESR. The primary model performed better than the simple one in C-index (87.5% vs. 83.0%, p = 0.004). There was no statistical significance between these two models in sensitivity (70.43% vs. 62.61%, p = 0.467), specificity (87.12% vs. 80.69%, p = 0.448), PPV (72.97% vs. 61.54%, p = 0.292), NPV (85.65% vs. 81.39%, p = 0.614), and accuracy (81.61% vs. 74.71%, p = 0.303). The primary model had good calibration and high levels of explained variation and discrimination in validation cohort. CONCLUSIONS This model can be used to predict MH in post-treatment patients with CD. It can also be used as an indication of endoscopic surveillance to evaluate mucosal healing in patients with CD after treatment.

Abstract
BACKGROUND Optimal strategies for using small-bowel capsule endoscopy (SBCE) in established small-bowel Crohn's disease (CD) remain uncertain. Mucosal healing (MH) has emerged as a valuable predictor of a flare-free disease. We aimed to evaluate the occurrence of disease flare on patients with small-bowel CD and MH, as well as to create a score identifying patients in higher risk for this outcome. METHODS We analyzed consecutive patients submitted to SBCE for assessment of MH and included those where MH was confirmed. The incidence of disease flare was assessed during follow-up (minimum 12 months). A score predicting disease flare was created from several analyzed variables. RESULTS From 47 patients with MH, 12 (25.5%) had a flare (versus 48.3% in excluded patients without MH; p = 0.01). Age ≤ 30 years (OR = 70; p = 0.048), platelet count ≥ 280 × 103/L (OR = 12.24; p = 0.045) and extra-intestinal manifestations (OR = 11.76; p = 0.033) were associated with increased risk of CD flare during the first year after SBCE with MH. These variables were used to compute a risk-predicting score-the APEX score-which assigned the patients to having low (0-3 points) or high-risk (4-7 points) of disease flare and had excellent accuracy toward predicting disease relapse (AUC = 0.82; 95%CI 0.64-0.99). CONCLUSION Patients with small-bowel CD and MH were not free of disease flares on the subsequent year, despite presenting lower rates when compared to those without MH. The APEX score demonstrated excellent accuracy at stratifying patients relapse risk and guiding further therapeutic options for patients achieving MH.

Abstract
Inflammatory bowel disease (IBD), with its 2 subtypes, Crohn's disease and ulcerative colitis, is a complex chronic condition. A precise definition of disease activity and appropriate drug management greatly improve the clinical course while minimizing the risk or cost. Artificial intelligence (AI) has been used in several medical diseases or situations. Herein, we provide an overview of AI for endoscopy in IBD. We discuss how AI can improve clinical practice and how some components have already begun to shape our knowledge. There may be a time when we can use AI in clinical practice. As AI systems contribute to the exact diagnosis and treatment of human disease, we should continue to learn best practices in health care in the field of IBD.

Abstract
OBJECTIVE To observe the effect of topical application of recombinant human basic fibroblast growth factor (bFGF) in patients with nasal vestibulitis. METHODS One hundred patients with nasal vestibulitis were randomly divided into two groups. Local application of bFGF + conventional medication was administered in the treatment group, while conventional medication was conducted in the control group. The healing of the nasal vestibular mucosa was observed. RESULTS The mucosal healing time was 18.3 ± 4.8 days in the treatment group and 36.2 ± 6.2 days in the control group. The data comparison revealed that the difference between groups was statistically significant (P < 0.01). The total effective rate was 98.0% in the treatment group and 90.0% in the control group, and the difference was not statistically significant between the two groups (P > 0.05). CONCLUSION Topical application of bFGF in patients with nasal vestibulitis could promote the growth of nasal mucosa, shorten the healing time of mucosal erosion, enhance the clinical treatment effect, and save a lot of treatment time for patients.

Abstract
To induce remission in luminal paediatric Crohn's disease (CD), the ESPGHAN/ECCO guideline recommends treatment with exclusive enteral nutrition (EEN) or oral corticosteroids. In newly diagnosed moderate-to-severe paediatric CD patients, we determined the proportion of patients in which EEN or corticosteroids induced remission and maintained remission on azathioprine monotherapy. We included patients from the "TISKids" study assigned to the conventional treatment arm. Patients were aged 3-17 years and had new-onset, untreated luminal CD with weighted paediatric CD activity index (wPCDAI) > 40. Induction treatment consisted of EEN or oral corticosteroids; all received azathioprine maintenance treatment from start of treatment. The primary outcome of this study was endoscopic remission defined as a SES-CD score < 3 without treatment escalation at week 10. Secondary outcomes included proportion of patients without treatment escalation at week 52. In total, 27/47 patients received EEN and 20/47 corticosteroids. At baseline, patient demographics and several inflammation parameters were similar between the two treatment groups. At 10 weeks, clinical remission rates were 7/23 (30%) for EEN and 7/19 (37%) for corticosteroids (p = 0.661). Twenty-nine of 47 consented to endoscopy at 10 weeks, showing endoscopic remission rates without treatment escalation in 2/16 (13%) of EEN-treated patients and in 1/13 (8%) of corticosteroid-treated patients (p = 1.00). At week 52, 23/27 (85%) EEN-treated patients received treatment escalation (median 14 weeks) and 13/20 (65%) corticosteroid-treated patients (median 27 weeks), p = 0.070.Conclusion: In children with moderate-to-severe newly diagnosed CD, induction treatment with EEN or CS regularly is insufficient to achieve endoscopic remission without treatment escalation at week 10. Trial registration number: NCT02517684 What is Known: • Endoscopic remission is associated with a low risk of disease progression. • FL-IFX was superior to conventional treatment in achieving and maintaining remission in paediatric patients with moderate-to-severe CD the first year from diagnosis. What is New: • In children with newly diagnosed moderate-to-severe CD, clinical remission rates and endoscopic remission rates without treatment escalation at week 10 were 30% and 13% after EEN and 37% and 8% after corticosteroid induction treatment. • The current treatment target was often not achieved by either EEN or corticosteroid induction treatment after bridging to azathioprine.

Abstract
BACKGROUND Optimization of treatment with biologics is currently an unmet need for patients with ulcerative colitis (UC). Real-world studies provide neutral estimates of drug efficacy and safety within unselected patient populations and allow for the recognition of specific characteristics that affect response to therapy. AIMS We aimed to depict the efficacy of vedolizumab in patients with UC in a real-world setting and identify prognosticators of improved outcomes. METHODS Patients with active UC who commenced treatment with vedolizumab were prospectively followed up. Patient-reported outcomes (PROs) and clinical/endoscopic-reported outcomes were recorded at baseline and at weeks 14 and 54. Predefined endpoints of early and persistent efficacy were analyzed against clinical characteristics to identify prognostic factors for response. RESULTS We included 96 patients (anti-TNF-exposed = 38.5%). At week 14, 73 patients (76%) had clinical response and 54 (56.3%) clinical remission. At week 54, the primary endpoint of vedolizumab persistence was met by 72 patients (75%), whereas steroid-free clinical remission by 59.4%. Among patients who had endoscopy, rates for mucosal healing (Mayo endoscopic score of 0) were 29.8% at week 14 and 44.6% at week 54, respectively. Vedolizumab treatment led to significant improvements in quality of life. Corticosteroid-refractory or anti-TNF-refractory disease, articular manifestations, and high baseline UC-PRO2 were associated with decreased efficacy of vedolizumab in the primary and secondary outcomes. CONCLUSIONS Vedolizumab is characterized by high efficacy and long-term treatment persistence in UC. More aggressive disease, as indicated by refractoriness to steroids or anti-TNFs and elevated baseline PROs, may predict suboptimal response and help pre-treatment prognostic stratification of patients.

Abstract
INTRODUCTION Physicians are often required to make treatment decisions for patients with Crohn's disease on the basis of limited objective information about the state of the patient's gastrointestinal tissue while aiming to achieve mucosal healing. Tools to predict changes in mucosal health with treatment are needed. We evaluated a computational approach integrating a mechanistic model of Crohn's disease with a responder classifier to predict temporal changes in mucosal health. METHODS A hybrid mechanistic-statistical platform was developed to predict biomarker and tissue health time courses in patients with Crohn's disease. Eligible patients from the VERSIFY study (n = 69) were classified into archetypical response cohorts using a decision tree based on early treatment data and baseline characteristics. A virtual patient matching algorithm assigned a digital twin to each patient from their corresponding response cohort. The digital twin was used to forecast response to treatment using the mechanistic model. RESULTS The responder classifier predicted endoscopic remission and mucosal healing for treatment with vedolizumab over 26 weeks, with overall sensitivities of 80% and 75% and overall specificities of 69% and 70%, respectively. Predictions for changes in tissue damage over time in the validation set (n = 31), a measure of the overall performance of the platform, were considered good (at least 70% of data points matched), fair (at least 50%), and poor (less than 50%) for 71%, 23%, and 6% of patients, respectively. CONCLUSION Hybrid computational tools including mechanistic components represent a promising form of decision support that can predict outcomes and patient progress in Crohn's disease.

Abstract
BACKGROUND Crohn's disease is a progressive inflammatory bowel disease. Persistent untreated inflammation can cumulatively result in bowel damage in the form of strictures, fistulas, and fibrosis, which can ultimately result in the need for major abdominal surgery. Mucosal healing has emerged as an attractive, yet ambitious goal in the hope of preventing long-term complications. SUMMARY Clinical remission is an inadequate measure of disease activity. Noninvasive markers such as fecal calprotectin, CRP, or small bowel ultrasound are useful adjunct tools. However, endoscopic assessment remains the cornerstone in building a treatment plan. Achieving complete mucosal healing has proved to be an elusive goal even in the ideal setting of a clinical trial. KEY MESSAGES Aiming for complete mucosal healing in all patients may result in overuse of medications, higher costs, and potential side effects of aggressive immunosuppressive treatment. More practical goals such as relative or partial healing, for example, 50% improvement in inflammation and reduction in size of ulcers, ought to be considered, particularly in difficult-to-treat populations.

Abstract
BACKGROUND Endoscopic remission is an increasingly recognized important therapeutic endpoint in the management of patients with UC. SUMMARY The Mayo Endoscopic Score (MES) remains the most common endoscopic index recommended in guidelines and widely used in clinical trials and in clinical practice. The MES is easy, simple, and practical but is suboptimal at providing an accurate depiction of segmental healing and/or at measuring a substantial but incomplete response across the spectrum of endoscopic inflammation. Other endoscopic scores have been proposed but have not received wide recognition or adoption.

Abstract
BACKGROUND Crohn's disease (CD) is a chronic inflammatory disorder affecting the gastrointestinal tract with disease behaviour based on the depth and severity of mucosal injury. Cumulative injury can result in complications including stricture formation and penetrating complications which often require surgical resection of diseased segments of the intestine resulting in significant morbidity. Accurate assessment of disease activity and appropriate treatment is essential in preventing complications. SUMMARY Treatment targets in the management of CD have evolved with the advent of more potent immunosuppressive therapy. Targeting the resolution of sub-clinical inflammation and achieving mucosal healing is associated with the prevention of stricturing and penetrating complications. Identifying non-invasive modalities to assess mucosal healing remains a challenge. KEY MESSAGES Mucosal healing minimizes the risk of developing disease complications, prolongs steroid-free survival, and reduces hospitalization and the need for surgical intervention.

Abstract
Background Epidemiological evidence on the association between physical activity (PA) and ulcerative colitis (UC) is limited, and the effect of PA on the prognosis of UC is currently unknown. We evaluated the association between PA and clinical outcomes, including clinical remission and mucosal healing (MH), in Japanese patients with UC. Methods The study subjects were 327 Japanese patients with UC. Subjects were asked about the average time spent per day on 4 types of PA (sedentary, standing, walking, and strenuous activity) and metabolic equivalents (METs) using a validated questionnaire. Clinical outcomes were complete MH, MH, and clinical remission. The association between PA, including hours spent on each type of PA and average daily METs, and clinical outcomes was assessed by multivariate logistic regression. Results Plentiful strenuous activity was significantly inversely associated with MH and complete MH after adjustment (MH: adjusted odds ratio [OR] 0.45, 95% confidence interval [CI] 0.23-0.89; complete MH: adjusted OR 0.24, 95%CI 0.07-0.62; P for trend=0.008). A very high daily MET total was significantly inversely associated with complete MH after adjustment (adjusted OR 0.37, 95%CI 0.16-0.80; P for trend=0.010). In contrast, no association between PA and clinical remission was found (plentiful strenuous activity: adjusted OR 1.10, 95%CI 0.55-2.23; very high daily total METs: adjusted OR 0.74, 95%CI 0.37-1.46). Conclusion In Japanese patients with UC, time spent per day on strenuous activity and total PA per day may be significantly inversely associated with complete MH, but not with clinical remission.

Abstract
BACKGROUND AND AIM Epithelial regeneration, a critical step for the mucosal healing in inflammatory bowel disease, is tightly regulated by stem cells. Therefore, identification of the specific factors that induce stem cell proliferation could contribute to the development of effective strategies for treating inflammatory bowel disease. Recombinant soluble thrombomodulin (rsTM) has previously been shown to promote cell proliferation in skin and corneal wound healing in murine models, but its effects on intestinal epithelial cell proliferation remains unclear. METHODS Mouse intestinal organoids and dextran sulfate sodium (DSS)-induced colitis mouse model were used to assess the effects of rsTM on proliferation of intestinal epithelial cells. The size and budding morphologies of organoids were studied by confocal microscopy. The gene expression levels were analyzed by quantitative real-time polymerase chain reaction and immunofluorescence analysis. The effects of rsTM on DSS-induced colitis were investigated by evaluating body weight changes, colon length, histological score, and survival rate. RESULTS The rsTM markedly stimulated the growth of intestinal organoids, thereby increasing the surface areas and budding phenotypes of the organoids. rsTM also significantly upregulated the gene expression of intestinal stem cell-specific and epithelial cell-specific markers in a dose-dependent manner. Furthermore, the treatment with high concentrations of rsTM significantly improved the recovery of body weight, histological outcomes, colon length shortening, and prolonged the survival of mice with colitis. CONCLUSIONS The rsTM promotes intestinal stem cell proliferation in intestinal organoids and enhances the mucosal healing during recovery phase in DSS-induced colitis.

Abstract
BACKGROUND Data concerning of the effectiveness of infliximab in very early onset Crohn's disease patients are rare. AIM To assess the effectiveness and safety issues of infliximab treatment for this rare cohort. METHODS The pediatric Crohn's disease activity index, Crohn's disease endoscopic index score, height, and weight were retrospectively recorded at baseline, week 14, and week 54. The rates of clinical remission and mucosal healing and growth of patients were compared between patients younger and older than 6 years of age. Loss of response or non-response to infliximab and adverse events were assessed during the entire treatment period. RESULTS Sixty-five patients were enrolled in the study. Sixty-four percent and 40.0% of very early onset Crohn's disease patients achieved clinical remission and mucosal healing after induction therapy. Adjusted for the covariances, very early disease onset had no association with primary non-response (p = 0.360) or mucosal healing (p = 0.361). Early disease onset was associated with discontinuation of infliximab due to adverse events (hazard ratio [HR] 7.15, 95% CI 1.73-29.51, p = 0.006). Patients < 6 years had lower body mass index for age z score improvement during the induction phase (p = 0.04). CONCLUSIONS Very early onset Crohn's disease patients had similar non-response rates and mucosal healing rates as those who were 6 years or older during induction therapy. Greater discontinuation of infliximab due to adverse events was observed in very early onset Crohn's disease patients.

Abstract
Background/Aims We evaluated whether anti-Saccharomyces cerevisiae antibody (ASCA) titers are associated with diagnostic findings, disease activity, Paris classification phenotypes, and persistence after infliximab (IFX) treatment in children with Crohn’s disease (CD). We also investigated the role of ASCA as a predictor of mucosal healing (MH) and clinical remission (CR). Methods This study included 61 CD patients aged 19 years or younger who were diagnosed and treated between September 2010 and January 2019 and followed for at least 1 year. ASCA was regularly measured at the diagnosis of CD and at least 1 year after IFX therapy. Results The average follow-up period was 3.8±3.4 years (range, 1.0 to 7.2 years). Regression analysis showed that the ASCA titer was the only factor associated with Simple Endoscopic Score for Crohn's Disease (SES-CD) or CR among all the parameters. In patients who had achieved MH (SES-CD=0), ASCA immunoglobulin G (IgG) was not associated with MH, but in patients without MH, ASCA IgG was associated with SES-CD (p=0.005) and CR (p<0.001). The cutoff value of ASCA IgG in patients with CR was 21.8 units. However, there was no difference in the relapse rate between the ASCA IgG-positive and -negative groups during the follow-up period. Conclusions In patients who have not achieved MH, ASCA IgG is closely related to mucosal damage and CR. Unlike Western studies, ASCA IgG may be more helpful in predicting prognosis than immunoglobulin A in Korean patients, but it is not an appropriate indicator to predict the relapse of CD.

Abstract
BACKGROUND Anastomotic failure causes morbidity and mortality even in technically correct anastomoses. Initial leaks must be prevented by mucosal reapproximation across the anastomosis. Healing is a concerted effort between intestinal epithelial cells (IECs), immune cells, and commensal bacteria. IEC TLR4 activation and signaling is required for mucosal healing, leading to inflammatory factor release that recruits immune cells to limit bacteria invasion. TLR4 absence leads to mucosal damage from loss in epithelial proliferation, attenuated inflammatory response, and bacteria translocation. We hypothesize after anastomosis, an imbalance in microbiota will occur due to a decrease in TLR4 expression and will lead to changes in the immune milieu. RESULTS We isolated fecal content and small intestinal leukocytes from murine, Roux-en-Y and end-to-end anastomoses, to identify microbiome changes and subsequent alterations in the regulatory and pro-inflammatory immune cells 3 days post-operative. TLR4+ IECs were impaired after anastomosis. Microbiome diversity was reduced, with Firmicutes, Bacteroidetes, and Saccharibacteria decreased and Proteobacteria increased. A distinct TCRβhi CD4+ T cells subset after anastomosis was 10-20-fold greater than in control mice. 84% were Th17 IL-17A/F+ IL-22+ and/or TNFα+. iNKT cells were increased and TCRβhi. 75% were iNKT IL-10+ and 13% iNKTh17 IL-22+. Additionally, Treg IL-10+ and IL-22+ cells were increased. A novel dendritic cell subset was identified in anastomotic regions that was CD11bhi CD103mid and was 93% IL-10+. CONCLUSIONS This anastomotic study demonstrated a decrease in IEC TLR4 expression and microbiome diversity which then coincided with increased expansion of regulatory and pro-inflammatory immune cells and cytokines. Defining the anastomotic mucosal environment could help inform innovative therapeutics to target excessive pro-inflammatory invasion and microbiome imbalance.

Abstract
BACKGROUND Mucosal healing (MH) has emerged as a key therapeutic target in inflammatory bowel disease (IBD), and achievement of this goal is documented by endoscopy with biopsy. However, colonoscopy is burdensome and invasive, and substitution with an accurate noninvasive biomarker is desirable.
AIM To summarize published data regarding the performance of noninvasive biomarkers in assessing MH in IBD patients.
METHODS We conducted a systematic review of studies that reported the performance of biomarkers in diagnosing MH in patients with IBD. The main outcome measure was to review the diagnostic accuracy of serum and fecal markers that showed promising utility in assessing MH.
RESULTS We screened 1301 articles, retrieved 46 manuscripts and included 23 articles for full-text analysis. The majority of the included manuscripts referred to fecal markers (12/23), followed by circulatory markers (8/23); only 3/23 of the included manuscripts investigated combined markers (serum and/or fecal markers). Fecal calprotectin (FC) was the most investigated fecal marker for assessing MH. In ulcerative colitis, for cutoff levels ranging between 58 mcg/g and 490 mcg/g, the sensitivity was 89.7%-100% and the specificity was 62%-93.3%. For Crohn’s disease, the cutoff levels of FC ranged from 71 mcg/g to 918 mcg/g (sensitivity 50%-95.9% and specificity 52.3%-100%). The best performance for a serum marker was observed for the endoscopic healing index, which showed a comparable accuracy to the measurement of FC and a higher accuracy than the measurement of serum C-reactive protein.
CONCLUSION Several promising biomarkers of MH are emerging but cannot yet substitute for endoscopy with biopsy due to issues with reproducibility and standardization.

Abstract
BACKGROUND Daphnein is the first new drug in China. In addition to the treatment of cardiovascular diseases and coronary heart disease, daphnein also has anti-inflammatory, anti-apoptosis, analgesia, and immunity-enhancing activities. Some studies have reported that daphnetin may inhibit the activities of cyclooxygenase and 5-ester oxidase and produce anti-inflammatory and anti-allergic reactions by inhibiting the synthesis of prostaglandin and leukotriene.
AIM To explore the efficacy of daphnetin in the treatment of colitis, and observe its effect on the composition of microbiota and the balance of regulatory T cells (Treg)/helper Th17 cells (Th17).
METHODS One hundred and eight patients with ulcerative colitis (UC) admitted to our hospital from June 2017 to November 2019 were selected and randomly divided into either a control group or an observation group, with 54 cases in each group. Both groups were given conventional Western medicine treatment, and the observation group was additionally given daphnetin. The total effective rate, Baron endoscopic score, Geboes mucosal histology score, modified Mayo activity index, intestinal flora distribution, Treg/Th17 balance changes [CD4+CD25+Foxp3+ Treg, interleukin-10 (IL-10), transforming growth factor β (TGF-β), CD3+CD4+IL-17A+ Th17, interleukin-17 (IL-17), and interleukin-21 (IL-21)], the simplified Chinese version of the Inflammatory Bowel Disease Quality of Life Scale (IBDQ) score, and adverse reactions of the two groups were compared.
RESULTS The total effective rate of the observation group was 90.74%, which was higher than that of the control group (70.37%; P < 0.05). Baron endoscopy score, Geboes mucosal histology score, and modified Mayo activity index of the observation group after treatment were significantly lower than those of the control group (P < 0.05). The numbers of E. coli, Bacteroides, and Enterococcus in the observation group were significantly lower and those of Lactobacillus and Bifidobacterium were significantly higher in the observation group than in the control group (P < 0.05). CD4+CD25+Foxp3+ Treg, IL-10, and TGF-β were significantly higher and CD3+CD4+IL-17A+ Th17, IL-17, and IL-21 were significantly lower in the observation group than in the control group (P < 0.05). The scores of emotional ability, intestinal symptoms, social ability, and systemic symptoms on the IBDQ scale were significantly higher in the observation group than in the control group (P < 0.05).
CONCLUSION Daphnetin can promote the healing of the intestinal mucosa of UC patients by modulating the microbiome composition and Treg/Th17 balance and effectively improve the patient's condition and quality of life, which is safe and reliable.

Abstract
PURPOSE Bilirubin is known to have antioxidant effects. Several pieces of evidence regarding association between serum bilirubin and UC exist. Three studies found that serum bilirubin was inversely associated with severity of ulcerative colitis (UC), but no evidence regarding an association between serum bilirubin and mucosal healing (MH) has yet been shown. Thus, we evaluated this issue among Japanese patients with UC. METHODS The study subjects consisted of 304 Japanese patients with UC. Serum total bilirubin and indirect bilirubin were divided into quartiles on the basis of the distribution of all study subjects (low, moderate, high, and very high). Several endoscope specialists were responsible for evaluating MH, which was defined as a Mayo endoscopic subscore of 0. The information on clinical remission was collected using medical records. RESULTS The mean age was 49.9 years, the percentage of male patients was 59.2%, and the percentage of MH was 29.3%. High serum total bilirubin was independently positively associated with MH (OR 2.26 [95%CI 1.13-4.61]. However, after adjustment for confounding factors, the association between total bilirubin and MH disappeared. Very high serum indirect bilirubin was independently positively associated with MH (OR 2.31 [95%CI 1.10-5.00], p for trend = 0.026). No association between bilirubin and clinical remission was found. CONCLUSIONS Among Japanese patients with UC, serum indirect bilirubin, but not total bilirubin, was significantly positively associated with MH but not clinical remission.

Abstract
Ultrasound has an excellent diagnostic performance when Crohn's disease is suspected, when performing an activity assessment, or determining the extension and location of Crohn's disease, very similar to other examinations such as MRI or CT. It has a good correlation with endoscopic lesions and allows the detection of complications such as strictures, fistulas or abscesses. It complements colonoscopy in the diagnosis and, given its tolerance, cost and immediacy, it can be considered as a good tool for disease monitoring. In ulcerative colitis, its role is less relevant, being limited to assessing the extent and activity when it is not possible with other diagnostic techniques or if there are doubts with these. Despite its advantages, its use in inflammatory bowel disease (IBD) is not widespread in Spain. For this reason, this document reviews the advantages and disadvantages of the technique to promote knowledge about it and implementation of it in IBD Units.

Abstract
BACKGROUND Mucosal healing is the main treatment goal for Crohn's disease. In this situation, some patients have difficulty with endoscopic evaluation of the entire small intestine. Crohn's disease is closely associated with the gut microbiota, but the relationship between the microbiome and disease activity in the small intestine remains unclear. We examined the association between the microbiome and endoscopic findings in the small intestine and determined whether the microbiome can predict mucosal healing. METHODS The patients with Crohn's disease who were scheduled for capsule or balloon-assisted endoscopy were included in this prospective study. Patients whose entire small intestine was evaluated were divided into two groups based on ulcerative findings. The microbiomes in the fecal samples were analyzed using 16S rRNA sequencing. RESULTS The 38 enrolled patients were divided into the ulcer group (24) and mucosal healing group (14). The ulcer group exhibited lower α diversity. Six genera, namely Faecalibacterium (P = 0.008), Lachnospira (P = 0.009), Paraprevotella (P = 0.01), Dialister (P = 0.012), Streptococcus (P = 0.025), and Clostridium (P = 0.028) were enriched in the mucosal healing group. A predictive score for mucosal healing was defined using these six genera. The area under the curve was 0.795 and the sensitivity and specificity for predicting mucosal healing were 0.643 and 0.917, respectively. CONCLUSIONS Fecal microbiome is corelated with disease activity in the entire small intestine in Crohn's disease patients. The predictive score proposed by microbiota characteristics was a potential biomarker for mucosal healing in the small intestine.

Abstract
BACKGROUND Perianal disease is associated with a disabling course of Crohn's disease (CD). We aim to study the impact of perianal disease on CD remission rates, after a 1-year course of infliximab in combination therapy with azathioprine. METHODS This was a retrospective, single-center cohort study, including consecutive CD patients on combination therapy, followed for 1 year since induction. The outcome variable was split into clinical and endoscopic remissions. The correlation toward the outcome variable was assessed with univariate and multivariate analysis and a survival assessment, using SPSS software. RESULTS We assessed 74 CD patients, of whom 41 (55.4%) were female, with a mean age of 36 years. Thirty-nine percent of the patients presented perianal disease at diagnosis (n = 29). We documented 70.3% clinical and 47.2% endoscopic remissions. Several variables had statistical significance toward the outcomes (endoscopic and clinical remissions) in the univariate analysis. After adjusting for confoundment, patients with perianal disease presented an odds ratio (OR) of 0.201 for achieving endoscopic remission (CI: 0.054-0.75, p value 0.017) and an OR of 0.203 for achieving clinical remission (CI: 0.048-0.862, p value 0.031). Sixty-six patients (89.2%) presented an initial response to treatment, from whom, 20 (30.3%) exhibited at least 1 disease relapse (clinical and/or endoscopic). Patients with perianal disease presented higher probability of disease relapse, displaying statistically significant difference on Kaplan-Meier curves (Breslow p value 0.043). CONCLUSION In the first year of combination therapy, perianal disease is associated with an 80% decrease in endoscopic and clinical remission rates and higher ratio of disease relapse.

Abstract
Background Mucosal healing (MH) has been indicated as the therapeutic goal for ulcerative colitis (UC). Platelet count is known as an inflammation evaluation. However, the association between platelet count and MH among patients with UC is still scarce. We therefore assessed this issue among Japanese patients with UC. Methods The study subjects consisted of 345 Japanese patients with UC. Platelet count was divided into quartiles on the basis of the distribution of all study subjects (low, moderate, high, and very high). Several endoscope specialists were responsible for evaluating MH and partial MH, which was defined as a Mayo endoscopic subscore of 0 and 0–1, respectively. Estimations of crude odds ratios (ORs) and their 95% confidence intervals (CIs) for partial MH and MH in relation to platelet count were performed using logistic regression analysis. Age, sex, CRP, steroid use, and anti-Tumor necrosis factor α (TNFα) preparation were selected a priori as potential confounding factors. Results The percentage of partial MH and MH were 63.2 and 26.1%, respectively. Moderate and very high was independently inversely associated with partial MH (moderate: OR 0.40 [95%CI 0.19–0.810], very high: OR 0.37 [95%CI 0.17–0.77], p for trend = 0.034). Similarly, moderate, high, and very high were independently inversely associated with MH (moderate: OR 0.37 [95% CI 0.18–0.73], high: OR 0.41 [95% CI 0.19–0.83], and very high: OR 0.45 [95% CI 0.21–0.94], p for trend = 0.033) after adjustment for confounding factors. Conclusions Among patients with UC, platelet count was independently inversely associated with MH
