Abstract
Diagnosing inflammatory bowel disease (IBD) can often be challenging, and differentiating between Crohn's disease and ulcerative colitis can be particularly difficult. Diagnostic procedures for IBD include laboratory tests, endoscopy, pathological tests, and imaging tests. Serological and stool tests can be easily performed in an outpatient setting and provide critical diagnostic clues. Although endoscopy is an invasive procedure, it offers essential diagnostic information and allows for tissue biopsy and therapeutic procedures. Video capsule endoscopy and device-assisted enteroscopy are endoscopic procedures used to evaluate the small bowel. In addition to endoscopy, magnetic resonance imaging, computed tomography, and ultrasound (US) are valuable tools for small bowel assessment. Among these, US is noninvasive and easily utilized, making its use highly practical in daily clinical practice. Endoscopic biopsy aids in the diagnosis of IBD and is crucial for assessing the histological activity of the disease, facilitating a thorough evaluation of disease remission, and aiding in the development of treatment strategies. Recent advances in artificial intelligence hold promise for enhancing various aspects of IBD management, including diagnosis, monitoring, and precision medicine. This review compiles current procedures and promising future tools for the diagnosis of IBD, providing comprehensive insights.

Kim DS, Hong J, Ryu K, Lee SH, Cho H, Yu J, Lee J, Kim JY. Factors Affecting Adherence to National Colorectal Cancer Screening: A 12-Year Longitudinal Study Using Multi-Institutional Pooled Data in Korea. J Korean Med Sci 2024; 39:e36. [PMID: 38288537 PMCID: PMC10825459 DOI: 10.3346/jkms.2024.39.e36] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 11/23/2023] [Indexed: 02/01/2024] Open
Abstract
BACKGROUND Consistent uptake of colorectal cancer (CRC) screening is important to reduce the incidence and mortality from advanced-stage CRC and increase the survival rate of the patients. We conducted a longitudinal study to determine the factors affecting CRC screening compliance in Korean adults using individual-level linked data from the Korean National Health and Nutrition Examination Survey, Korean National Health Insurance Service, and Korean Health Insurance Review and Assessment Service. METHODS We selected 3,464 adults aged 50-79 years as the study population and followed them for 12 years (January 2007-December 2018). The outcome variable was the level of adherence to CRC screening, categorized as nonadherent, intermittently adherent, and consistently adherent. An ordinal logistic regression model was designed to determine the socioeconomic factors, family history of CRC, and medical conditions that could facilitate the consistent uptake of CRC screening. RESULTS The results showed a significant and positive association between consistent uptake of CRC screening and the 100-150% income category (odds ratio [OR], 1.710; 95% confidence interval [CI], 1.401-2.088); clerical, sales and service job category (OR, 1.962; 95% CI, 1.582-2.433); residency at medium-sized cities (OR, 1.295; 95% CI, 1.094-1.532); high-school graduation (OR, 1.440; 95% CI, 1.210-1.713); married status (OR, 2.281; 95% CI, 1.946-2.674); use of employment-based national health insurance (OR, 1.820; 95% CI, 1.261-2.626); use of private insurance (OR, 2.259; 95% CI, 1.970-2.589); no disability (OR, 1.428; 95% CI, 1.175-1.737); family history of CRC (OR, 2.027; 95% CI, 1.514-2.714); and history of colorectal neoplasm (OR, 1.216; 95% CI; 1.039-1.422). CONCLUSION The lack of regular participation in CRC screening programs in the Republic of Korea was found to be an issue that requires attention. Policies on CRC screening must place increased emphasis on strengthening educational and public relations initiatives.

Abstract
The gut microbiome plays a pivotal role in maintaining human health, with numerous studies demonstrating that alterations in microbial compositions can significantly affect the development and progression of various immune-mediated diseases affecting both the digestive tract and the central nervous system (CNS). This complex interplay between the microbiota, the gut, and the CNS is referred to as the gut-brain axis. The role of the gut microbiota in the pathogenesis of neurodegenerative diseases has gained increasing attention in recent years, and evidence suggests that gut dysbiosis may contribute to disease development and progression. Clinical studies have shown alterations in the composition of the gut microbiota in multiple sclerosis patients, with a decrease in beneficial bacteria and an increase in pro-inflammatory bacteria. Furthermore, changes within the microbial community have been linked to the pathogenesis of Parkinson's disease and Alzheimer's disease. Microbiota-gut-brain communication can impact neurodegenerative diseases through various mechanisms, including the regulation of immune function, the production of microbial metabolites, as well as modulation of host-derived soluble factors. This review describes the current literature on the gut-brain axis and highlights novel communication systems that allow cross-talk between the gut microbiota and the host that might influence the pathogenesis of neuroinflammation and neurodegeneration.

Abstract
Background Objectives The pivotal of the study was to compare the effectiveness of education in disease-associated knowledge of Inflammatory Bowel Disease (IBD) patients between pre-test and post-test using the IBD-KNOW questionnaire and patient educational resources. Methods This study used a patient proforma and IBD- KNOW questionnaire to perform the study prospectively by interviewing method. The patient selection was based on inclusion and exclusion criteria by convenient sampling technique from November 2018 to July 2019 at a multispecialty hospital. Knowledge scores and inter-item correlation were calculated between the pre-test and post-test by R Programming software with p<0.05. Results Among 40 patients with IBD diagnosis, the baseline sociodemographic characteristics were recorded. The response rate of IBD knowledge between the pre-test and post-test resulted in significant differences with varying scales but the response rate was lesser in the domains of management and pregnancy-based questions in the pre-test and post-test. Conclusions Recently there was a swift in IBD incidence, this may be improved by affording suitable patient education and counseling for further knowledge level in managing the disease by coping strategy. On comparison between the pre-test and post-test, this study recommends innovative educational methods to enable continuing education for chronic disease which can be easily accessible and reliable for IBD patients.

Abstract
Since the development of the fiberoptic colonoscope in the late 1960s, colonoscopy has been a useful tool to diagnose and treat various intestinal diseases. This article reviews the clinical use of colonoscopy for various intestinal diseases based on present and future perspectives. Intestinal diseases include infectious diseases, inflammatory bowel disease (IBD), neoplasms, functional bowel disorders, and others. In cases of infectious diseases, colonoscopy is helpful in making the differential diagnosis, revealing endoscopic gross findings, and obtaining the specimens for pathology. Additionally, colonoscopy provides clues for distinguishing between infectious disease and IBD, and aids in the post-treatment monitoring of IBD. Colonoscopy is essential for the diagnosis of neoplasms that are diagnosed through only pathological confirmation. At present, malignant tumors are commonly being treated using endoscopy because of the advancement of endoscopic resection procedures. Moreover, the characteristics of tumors can be described in more detail by image-enhanced endoscopy and magnifying endoscopy. Colonoscopy can be helpful for the endoscopic decompression of colonic volvulus in large bowel obstruction, balloon dilatation as a treatment for benign stricture, and colon stenting as a treatment for malignant obstruction. In the diagnosis of functional bowel disorder, colonoscopy is used to investigate other organic causes of the symptom.

Abstract
Background and Aim The identification of ulcerative colitis (UC) and Crohn's disease (CD) is a key element interfering with therapeutic response, but it is often difficult for less experienced endoscopists to identify UC and CD. Therefore, we aimed to develop and validate a deep learning diagnostic system trained on a large number of colonoscopy images to distinguish UC and CD. Methods This multicenter, diagnostic study was performed in 5 hospitals in China. Normal individuals and active patients with inflammatory bowel disease (IBD) were enrolled. A dataset of 1,772 participants with 49,154 colonoscopy images was obtained between January 2018 and November 2020. We developed a deep learning model based on a deep convolutional neural network (CNN) in the examination. To generalize the applicability of the deep learning model in clinical practice, we compared the deep model with 10 endoscopists and applied it in 3 hospitals across China. Results The identification accuracy obtained by the deep model was superior to that of experienced endoscopists per patient (deep model vs. trainee endoscopist, 99.1% vs. 78.0%; deep model vs. competent endoscopist, 99.1% vs. 92.2%, P < 0.001) and per lesion (deep model vs. trainee endoscopist, 90.4% vs. 59.7%; deep model vs. competent endoscopist 90.4% vs. 69.9%, P < 0.001). In addition, the mean reading time was reduced by the deep model (deep model vs. endoscopists, 6.20 s vs. 2,425.00 s, P < 0.001). Conclusion We developed a deep model to assist with the clinical diagnosis of IBD. This provides a diagnostic device for medical education and clinicians to improve the efficiency of diagnosis and treatment.

Abstract
Clinical investigations in inflammatory bowel disease (IBD) patients have provided increasing evidence that eosinophils contribute to chronic intestinal inflammation. Accumulation of eosinophils in the gastrointestinal tract correlates with the variations of eosinophil regulatory molecules; however, their role in gastrointestinal dysfunction in IBD has not been fully elucidated. This review will describe the development and characterization of gastrointestinal eosinophils, mechanisms of eosinophil recruitment to the gastrointestinal tract. Moreover, the eosinophil-induced changes to the enteric nervous system associated with disease severity and gastrointestinal dysfunction will be analyzed with suggestive molecular pathways for enteric neuronal injury. Current and potential therapeutic interventions targeting eosinophils will be discussed.

Abstract
Cytomegalovirus (CMV) typically causes gastrointestinal infections in immunocompetent patients. Colonic perforations secondary to CMV are exceeding rare. We describe a 88-year-old male presenting with a week-long history of intractable abdominal discomfort, bloating, nausea and diarrhea. Flexible sigmoidoscopy revealed significant ulceration with yellowish slough. Emergency surgery was performed subsequently in view of multiple perforations in the rectosigmoid junction. CMV gastrointestinal infections demonstrated an ischemic process secondary to vasculitis, which accelerated the pathway to colonic perforation. CMV gastrointestinal infection should be considered as a differential diagnosis in patients with colonoscopy findings similar to ischemic colitis and Clostridium difficile infections.

Abstract
This study assessed the occurrence of indicators for suboptimal biologic therapy among ulcerative colitis (UC) and Crohn’s disease (CD) patients over time in the United States (US). Data from a large US claims database (2005–2013) were used to retrospectively identify patients with diagnosed with either UC or CD who were new biologic users. Indicators of suboptimal biologic therapy included: dose escalation during the maintenance phase, discontinuation of the initial biologic, switch to another biologic within 90 days following the last day of supply of the initial biologic, augmentation with a non-biologic systemic therapy, UC- or CD-related surgery, UC- or CD-related urgent care, and development of fistula (for CD only). Kaplan-Meier analyses were used. A total of 1,699 UC and 4,569 CD patients were included. Among UC patients, 51.1% and 90.9% experienced ≥1 indicator of suboptimal biologic therapy within 6 months and 36 months of biologic therapy initiation, respectively. Among CD patients, 54.3% and 91.4% experienced ≥1 indicator of suboptimal biologic therapy within 6 and 36 months of biologic therapy initiation, respectively. For both UC and CD patients, the most frequent indicators of suboptimal biologic therapy were discontinuation, dose escalation and augmentation. In conclusion, this study found that the occurrence of suboptimal biologic therapy is common among patients with UC and CD, with approximately 90% of patients experiencing at least one indicator of suboptimal biologic therapy within 36 months of biologic treatment initiation.

Abstract
AIM: To evaluate significant risk factors for incomplete colonoscopy at a Japanese academic hospital.
METHODS: A total of 11812 consecutive Japanese people were identified who underwent a colonoscopy at an academic hospital. A multiple logistic regression model was used to evaluate retrospectively the significant risk factors for incomplete colonoscopy.
RESULTS: The cecal intubation rate was 95.0%. By univariate analysis, age, female sex, poor bowel cleansing, and a history of abdominal or pelvic surgery were significant risk factors for incomplete colonoscopy (P < 0.001). Moreover, age- and sex-adjusted analysis showed that significant risk factors for incomplete colonoscopy were female sex (OR = 1.38, 95%CI: 1.17-1.64, P = 0.0002), age ≥ 60 years old (OR = 1.44, 95%CI: 1.22-1.71, P < 0.0001), a history of prior abdominal or pelvic surgery (OR = 1.55, 95%CI: 1.28-1.86, P < 0.0001), poor bowel cleansing (OR = 4.64, 95%CI: 3.69-5.84, P < 0.0001), and inflammatory bowel disease (IBD) (OR = 1.48, 95%CI: 1.13-1.95, P = 0.0048). In Japanese men, by age-adjusted analysis, IBD (OR = 1.69, 95%CI: 1.18-2.43, P = 0.005) was an independent risk factor for incomplete colonoscopy.
CONCLUSION: Several characteristics in the Japanese population were identified that could predict technical difficulty with colonoscopy.

Abstract
BACKGROUND AND AIM Focusing on TNFSF15 instead of NOD2, we set out to evaluate whether combining serologic and genetic markers could distinguish between Crohn’s disease (CD) and ulcerative colitis (UC), and whether they could be used to stratify the disease behavior of Taiwanese CD patients. METHODS Clinical information, serum isolation, and DNA were collected after obtaining informed consent. The serological markers were analyzed by ELISA kits and the genetic analysis for TNFSF15 single-nucleotide polymorphisms (SNPs) by Sequenom. Statistic analyses were conducted by SAS 9.2 (Cary, NC, USA). RESULTS This study included 108 patients (55 CD, 53 UC) and 60 healthy controls. An initial low positive rate and low sensitivity for the serological markers led us to reset the cut-off values. This reset cut-off for ASCA IgA yielded a sensitivity of 0.291 and specificity of 0.925 for differentiating CD from UC patients. The reset cut-off value for p-ANCA (anti-MPO) had a sensitivity of 0.461 and a specificity of 0.817 for differentiating inflammatory bowel disease patients from healthy controls. Among the TNFSF15 SNPs, rs4263839 associated with CD in Taiwan (P = 0.005), haplotype analysis did not increase the association. Combining the genetic marker TNFSF15 (rs4263839) and serological marker ASCA IgA increased the area under the curve from 0.61 to 0.70 for predicting stenosis/perforating phenotype, compared to ASCA IgA alone. CONCLUSIONS Serological markers need to be tested and tailored to different countries/ethnicities. Combining the genetic marker TNFSF15 with ASCA IgA increased the power of predicting stenosis/perforating phenotype in CD patients with TNFSF15 but not with a NOD2 genetic background.
