Background: The main treatment for Celiac Disease (CD) is the gluten-free diet (GFD). However, in some CD patients, iron deficiency anemia can be persistent despite a GFD.

Aim: In this study, we aim to evaluate the prevalence of anemia in both adults and children with CD at the diagnosis and during the GFD.

Methods: In this cross-sectional study including both adults and children with CD, the demographic characteristics and hemoglobin, iron, folate and vitamin B12 levels were retrospectively retrieved from patients' medical records at the time of diagnosis (T0); after 3-5 years (T1) and after 8-10 years (T2) of GFD.

Results: 311 CD patients (184 adults and 127 pediatric patients) were included in the study. No difference was observed in the prevalence of anemia in the overall population after 3-5 years of GFD in both adult and pediatric patients compared to the diagnosis. At 8-10 years, in the adult patient's group, a significant reduction in the prevalence of anemia was observed (24% vs. 17.8% p = 0.043).

Conclusions: Despite the GFD and a very long observational period the diagnosis of anemia persists in 17.8% and 4.4% of adult and pediatric patients, respectively. The diagnostic delay (longer in adult patients) and a more pronounced ultrastructural mucosal injury could play a role in the persistence of anemia despite the GFD.

Background: To investigate the short-term efficacy of laparoscopic proximal gastrectomy (LPG) with modified side overlap anastomosis in comparison with laparoscopic total gastrectomy (LTG) with Roux-en-Y anastomosis.

Methods: A retrospective cohort study was conducted. The clinicopathological data of 262 patients who underwent LPG or LTG for upper gastric adenocarcinoma from January 2016 to December 2022 were collected. Among 262 patients, 20 who underwent LPG with a modified side overlap anastomosis were assigned to the side overlap group, and 242 who underwent LTG with Roux-en-Y anastomosis were assigned to the Roux-en-Y group. After 1:1 matching of patients in the side overlap and Roux-en-Y groups via the propensity score matching method, 15 patients were included in this study. The outcome measures included the following: (1) intraoperative conditions, (2) postoperative recovery and (3) follow-up information.

Results: (1) Intraoperative conditions. Compared with the Roux-en-Y group, the side overlap group had a longer digestive tract reconstruction time. No significant difference was observed in the total operation time or amount of intraoperative blood loss. (2) Postoperative recovery. No statistically significant difference was detected between the side overlap and Roux-en-Y groups in terms of indicators, such as first anal exhaust time, first postoperative liquid intake time, postoperative hospitalization time and postoperative complications. (3) Follow-up information. The body mass index, haemoglobin, albumin, and Nutritional Risk Screening 2002 scores of the side overlap group were better than those of the Roux-en-Y group at 12 and 18 months after surgery. No significant difference was observed in the gastroesophageal reflux disease scale score or occurrence of ≥ Grade B reflux oesophagitis at 12 and 18 months after surgery between the side overlap and Roux-en-Y groups.

Conclusions: LPG with a modified side overlap anastomosis is safe and feasible for the treatment of upper gastric adenocarcinoma and can achieve good antireflux effects. In addition, compared with traditional LTG, the postoperative nutritional status after LTG is better.

Objective: To determine whether intratumoral and peritumoral radiomics derived from dual-phase contrast-enhanced CT imaging could predict lymph node metastasis (LNM) in gastric cancer.

Methods: Patients with gastric cancer from January 2017 to January 2022 were retrospectively collected and were randomly divided into training cohort (n = 287) and test cohort (n = 121) with a ratio of 7: 3. Clinical features and traditional radiological features were analyzed to construct clinical model. Radiomics features based on intratumoral (ITV) and peritumoral volumetric (PTV) regions of the tumor were extracted and screened to construct radiomics models. Clinical-radiomics combined model was constructed by the most predictive radiomics features and clinical independent predictors. The correlation between LNM predicted by the best model and 2-year disease-free survival (DFS) was evaluated by the Kaplan-Meier analysis.

Results: CT-LNM and CT-T stage were independent predictors of LNM. Compared with other radiomics models, ITV + PTV on atrial and venous phase (ITV + PTV-AP + VP) radiomics model presented moderate AUCs of 0.679 and 0.670 in the training cohort and validation cohort, respectively. Among the models, clinical-radiomics combined model achieved the highest AUC of 0.894 and 0.872 in the training and test cohorts, and 0.744 and 0.784 in the T1-2 and T3-4 subgroups, respectively. Clinical-radiomics combined model based LNM could stratify patients into high-risk and low-risk groups, and 2-year DFS of high-risk group was significantly lower than that of low-risk group (p < 0.001).

Conclusion: Clinical-radiomics combined model integrating CT-LNM, CT-T stage, and ITV-PTV-AP + VP radiomics features could predict LNM, and this combined model based LNM was associated with 2-year DFS.

Background: Gastrointestinal endoscopy examinations were commonly associated with patient uncertainty, anxiety, and sleep disturbances. Simulated animated video education has emerged as a potential intervention to address these psychosocial aspects in the healthcare setting. This study explores the impact of simulated animated video education on patients' disease uncertainty, anxiety, and sleep quality in the context of digestive endoscopy examinations.

Methods: A total 166 patients who underwent digestive endoscopy examinations were conducted and divided into the conventional education group (n = 77) and the simulated animated video education group (n = 89). Disease uncertainty was assessed using the Mishel's Uncertainty in Illness Scale (MUIS), anxiety was evaluated using the Hamilton Anxiety Rating Scale (HAMA), and sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI).

Results: Both conventional and simulated animated video education interventions led to a reduction in disease uncertainty, anxiety levels, and improvement in sleep quality post-education and at the one-month follow-up. However, the simulated animated video education group exhibited greater reductions in disease uncertainty (post-education: 86.69 ± 2.65 vs. 85.65 ± 3.46, P = 0.031; follow-up: 82.57 ± 4.57 vs. 81.21 ± 3.69, P = 0.038), anxiety (post-education: 19.88 ± 3.78 vs.18.75 ± 3.42, P = 0.046; follow-up: 18.59 ± 3.4 vs. 17.54 ± 3.25, P = 0.046), and improvement in sleep quality (post-education: 5.57 ± 1.25 vs. 5.15 ± 1.1, P = 0.023; follow-up: 5.22 ± 1.13 vs. 4.89 ± 0.86, P = 0.038) compared to the conventional education group.

Conclusion: The study findings suggest that simulated animated video education was associated with reduced disease uncertainty, alleviated anxiety, and improved sleep quality among patients undergoing gastrointestinal endoscopy.

Objectives: We evaluated the epidemiology and clinical characteristics of colorectal polyps to formulate an appropriate screening program.

Methods: A retrospective chart review was conducted on all patients who underwent complete colonoscopy at Jordan University Hospital from January to September 2018. Demographics, comorbidities, lifestyle habits, medication history, family history of cancer, laboratory parameters, quality of bowel preparation, and polyp characteristics were evaluated. Binary logistic regression was utilized to find predictors of colorectal polyps.

Results: A total of 965 patients were included in the study, with a mean age of 53.9 ± 17.1 years and a male predominance (52.7%). Polyps were detected in 28.1% of patients, with 18% having one polyp, 10.4% having two polyps, and 3.3% having more than two polyps. Multivariate analysis demonstrated that older age, high BMI, male gender, diabetes mellitus, dyslipidemia, ischemic heart disease, and family history of CRC were positive predictors of polyps. The right colon (cecum and ascending colon) was the most common location for polyps (51%), followed by the sigmoid colon (24.8%). The most common histologic subtype of polyps was tubular adenoma (48.2%). The prevalence of CRC was 18.65 per 1000 patients.

Conclusion: We highlight the fair prevalence of colorectal polyps and CRC in a Jordanian cohort. Awareness campaigns, screening strategies, and promotion of healthy lifestyles could help alleviate the burden of the disease, particularly among patients with classical risk factors for CRC.

Background: The operation sequence of bidirectional endoscopy with topical anesthesia varies among endoscopists, which interferes with clinical procedure. The study aimed to investigate the influence of different operation sequences on the outcomes of quality indicators and improve bidirectional endoscopy performance.

Methods: A randomized trial was conducted at the affiliated hospital of a medical university in China. Outpatients who initially underwent bidirectional endoscopy with topical anesthesia were enrolled. Eligible patients were randomized to either the colonoscopy-first group or the esophagogastroduodenoscopy-first group. Dyclonine hydrochloride mucilage and oxybuprocaine hydrochloride gel were administered for topical anesthesia. After finishing the previous process, the subsequent one was performed immediately. Quality indicators of esophagogastroduodenoscopy and colonoscopy were compared between the groups.

Results: Analyzing 395 combined procedures, the cecal intubation rate, discomfort score during esophagogastroduodenoscopy, examination score of esophagogastroduodenoscopy, and colorectal polyp detection rate were similar between the two groups. The colonoscopy-first group had lower colonic spasm incidence (66.0% vs. 30.3%, p < 0.001), shorter median cecal intubation time (254 s vs. 211 s, p < 0.001), and higher colonoscopy comfort rate (72.5% vs. 85.6%, p < 0.001) compared with the esophagogastroduodenoscopy-first group. Operation sequence significantly affected the incidence of colonic spasm (OR 4.739, 95%CI 3.054-7.352, p = 0.000), which correlated with cecal intubation time (r = 0.196, p < 0.001) and patient discomfort score (r = 0.136, p = 0.007).

Conclusion: In bidirectional endoscopy with topical anesthesia, performing colonoscopy first may improve colonoscopy performance without affecting esophagogastroduodenoscopy examination. The study was registered prior to conducting the research in the Chinese Clinical Trial Registry ( https://www.chictr.org.cn ) on November 7, 2023 with the trial identification number ChiCTR2300077408.

Background: Given the inherent limitations of invasive biopsy and the insufficient accuracy of liver-related serum biomarkers, there is an urgent need for the development of reliable, non-invasive imaging techniques for the diagnosis of liver fibrosis. This study aims to investigate the correlation between magnetic resonance imaging (MRI) T1/T2 mapping sequences and biomarkers of collagen deposition and ongoing systemic inflammation, and to evaluate the potential of T1/T2 mapping as a non-invasive method for the accurate diagnosis of liver fibrosis.

Methods: A mouse model of carbon tetrachloride (CCl₄)-induced liver fibrosis was established and T1/T2 mapping were performed at different weeks of treatment. The histopathological analysis, collagen quantification, and inflammatory factors measurements (IL-1, IL-6, TNF-α) were conducted to correlate MRI parameters with collagen deposition and inflammation. Statistical analysis was performed using IBM SPSS Statistics (version 22.0, Chicago, IL, USA) and Origin 2018 (OriginLab Corporation, Northampton, MA, USA).

Results: The principal findings indicated that T1 and T2 values exhibited a progressive increase with the severity of fibrosis, demonstrating a positive correlation with collagen deposition and inflammatory factors, especially the hydroxyproline content (r = 0.880, P < 0.001). The HYP content exhibited a progressive increase with advancing fibrosis stages (ρ = 0.914, P < 0.001). Similarly, T1 values increased significantly across fibrosis stage(ρ = 0.854, P < 0.001). Statistical comparison of these coefficients revealed no significant difference (Z = 1.031, P = 0.303). ROC curve analysis showed that T1 mapping was more accurate than T2 mapping in detecting collagen deposition and inflammation.

Conclusions: This study highlighted the potential of T1/T2 mapping as non-invasive and quantitative biomarkers for diagnosing and staging liver fibrosis, providing new insights into the onset and progression of liver fibrosis.

Background: The accurate prognosis of gastrointestinal stromal tumors (GISTs) has garnered substantial attention, yet a gap persists in understanding the influence of inflammatory markers on the prognosis of high-risk GIST patients. This study investigated the relationship between various factors and the prognosis of high-risk GIST patients, with a specific focus on first recurrence-free survival (RFS) and overall survival (OS) as crucial prognostic indicators.

Methods: A comprehensive collection of clinical data was conducted on 145 high-risk GIST patients meeting specific inclusion and exclusion criteria at 17 medical centers in Ningxia Hui Autonomous Region, China, covering the period from January 2013 to December 2019. Single-factor analysis and survival curves were used to analyze the variables, while the Cox regression model evaluated independent prognostic factors.

Results: Within the cohort, a balanced male-to-female ratio of 1:1.1 was observed. Univariate analysis revealed compelling associations between RFS and age, preoperative neutrophil-to-lymphocyte ratio (NLR), preoperative platelet-to-lymphocyte ratio (PLR), preoperative systemic immune-inflammatory index (SII), preoperative prognostic nutritional index (PNI), mitotic index, and whether or not imatinib (IM) was taken regularly in high-risk GIST patients (P < 0.05). Except age, these other variables were also significantly correlated with OS (P < 0.05). Cox regression analysis showed that age, preoperative PNI, mitotic index and postoperative IM adjuvant therapy independently affected RFS (P < 0.05). In addition, preoperative PNI and postoperative IM adjuvant therapy were also independent factors of OS, with statistical significance (P < 0.05). Age was negatively correlated with RFS, and early routine IM treatment after operation significantly reduced the risk of recurrence and death. Higher mitotic index is closely related to poor RFS, and higher preoperative PNI indicates a better prognosis.

Conclusion: A close correlation between young age, low preoperative PNI, high mitotic index, and lack of IM treatment had an unfavorable prognosis in high-risk GIST patients. Notably, the PNI was identified as a potential additional prognostic factor, enhancing the accuracy of predicting treatment efficacy and patient outcomes in high-risk patients with GISTs. Therefore, we advocate for the serious consideration of the PNI as a valuable addition to standard clinical practice for managing high-risk GIST patients.

Purpose: This retrospective study evaluates the clinical efficacy of the Intersphincteric Approach with Internal Incision combined with Counter-Drainage (IAICD) for Deep Perianal Abscess (DPA), thereby providing a foundation for selecting optimal surgical treatment methods in clinical practice.

Methods: Using a retrospective cohort study design, we analyzed the clinical data of 120 patients who underwent inpatient surgical treatment for DPA at our hospital from January 2022 to June 2023. Of these, 57 patients underwent the IAICD (treatment group), while 63 patients received incision-drainage (control group). Clinical data from both groups were collected for statistical analysis. The primary outcomes measured were clinical efficacy, anal function scores and appearance scores. Secondary outcomes included postoperative pain, operation time, wound healing time and length of hospital stay.

Results: The treatment group had 52 cured cases, with a cure rate of 52/57 (91.2%), whereas the control group had 48 cured cases, with a cure rate of 48/63 (76.2%). The treatment group's clinical efficacy was significantly better than the control group (P = 0.03). The operation time was longer in the treatment group compared to the control group (P < 0.01). There were no significant differences between the two groups in terms of anal function scores, appearance scores, postoperative pain, wound healing time and length of hospital stay (P > 0.05). Multivariate logistic regression analysis revealed that IAICD was a protective factor for the clinical efficacy of DPA patients (P = 0.01), While wound healing time and a history of perianal surgery were identified as independent risk factors associated with poor prognosis in patients with DPA (P = 0.039, P = 0.032).

Conclusion: For patients with DPA who have high expectations for minimizing postoperative recurrence, a comprehensive preoperative evaluation-including a history of prior perianal surgery-precise intraoperative localization of the internal opening, and meticulous postoperative wound care can collectively optimize clinical outcomes. The IAICD procedure not only preserves anal sphincter function but also effectively reduces the recurrence rate of postoperative abscesses or fistula formation.

Background: Current studies suggest a potential link between inflammatory bowel disease (IBD), comprising Crohn's disease (CD) and ulcerative colitis (UC), and cardiovascular diseases, such as stroke. This study aimed to assess the risk of stroke in IBD patients compared to general population.

Methods: Systematic search was done in PubMed, Embase, CENTRAL, Scopus, and CINAHL databases for studies published till September 2023. Using a random-effects model, the hazard ratios (HRs) with 95% confidence intervals (CIs) for stroke occurrence were calculated. Subgroup analyses were done to estimate pooled HR with 95%CI for CD, UC, and overall IBD cases separately. Publication bias assessment was done by Begg's and Egger's tests.

Results: Thirteen studies with 2,802,955 participants were included. IBD patients in general had significantly higher risk of stroke, with HR of 1.30 [95% CI 1.21-1.39]. Subgroup analysis demonstrated an HR of 1.35 [95% CI 1.22-1.49] for CD and 1.15 [95% CI 1.09-1.22] for UC. Substantial heterogeneity was detected across studies, with no substantial publication bias. Sensitivity analyses affirmed the stability of findings.

Conclusion: IBD in general, and Crohn's disease in particular are associated with significantly higher risk of stroke. Our findings further emphasize the importance of cardiovascular risk assessment and management strategies in IBD care.
