Aims: Our study aimed to investigate the association between the relative fat mass (RFM) and gallstones in adults.

Methods: Information obtained from the National Health and Nutrition Examination Survey (NHANES) 2017-2023 was utilized to examine the correlation between RFM and gallstones based on weighted multivariable regression analysis, smoothing curve fitting, and threshold effect analyses. Using subgroup analysis and interaction tests, we investigated whether this association remained consistent across different populations. We evaluated the effectiveness of RFM and Body Mass Index (BMI) in detecting gallstones through receiver operating characteristic (ROC) analysis and by calculating the area under the curve (AUC).

Results: The study involved 7618 participants in total. RFM mean was 30.74 ± 5.68. Based on the fully adjusted model, gallstone prevalence was positively associated with RFM (OR = 1.09; 95% CI: 1.07-1.11; p < 0.001), with a 9% increase for each unit increase in RFM. This correlation was particularly evident among individuals under the age of 40 and among females. Smoothing curve fitting revealed a nonlinear association between RFM and the occurrence of gallstones, with an inflection point identified at 19.8. Additionally, ROC analysis showed that RFM (AUC = 0.674) outperformed BMI (AUC = 0.634) as a predictor of gallstone formation.

Conclusions: Higher RFM was associated with higher gallstone prevalence. RFM may be a more useful tool for gallstone prediction than BMI in the general population. Gallstones may be alleviated or improved by RFM management at an early age.

Clinical trial number: Not applicable.

Background: Colorectal cancer (CRC) ranks as the third most prevalent cancer globally and the second leading cause of cancer-related mortality. This study investigates the diagnostic value of peripheral blood inflammatory indices, including the Cancer-Inflammation Prognostic Index (CIPI), Systemic Inflammation Response Index (SIRI), Hemoglobin-Albumin-Lymphocyte-Platelet (HALP) index, Neutrophil-to-Lymphocyte Ratio (NLR), and Platelet-to-Lymphocyte Ratio (PLR), in the early diagnosis of clinicopathological characteristics of CRC.

Method: This retrospective observational study involved 224 patients with CRC aged over 45, admitted to Rasoul-Akram Hospital from September 2019 to 2023, undergoing elective CRC surgery. Key demographic and clinicopathological data were collected alongside blood samples to derive inflammatory indices. Univariate and multivariate analyses were applied to determine metastasis and stage predictors. A receiver operating characteristic (ROC) analysis was performed to evaluate the SIRI diagnostic value in differentiating tumors with and without metastasis and the CIPI diagnostic value in differentiating tumors with high and low stage.

Results: The study identified a significant association between elevated SIRI levels and metastasis in univariate analysis (OR = 2.79, CI = 1.12-6.94). Multivariate analysis shows CIPI is associated with advanced tumor stages (OR = 1.97, CI = 1.14-3.38). According to the ROC curve, the optimal cut-off value of SIRI and CIPI was 1.376 (sensitivity 52.6%, specificity 60.8%, AUC = 61.5%) for diagnosing the metastasis and 7.114 (sensitivity 59.8%, specificity 57%, AUC = 57.9%) for diagnosing the tumor stage, respectively.

Discussion: The findings show that a higher SIRI value is associated with a higher chance of metastasis and a higher CIPI value is associated with a higher chance of advanced stages. Furthermore, the study advocates for the integration of these inflammatory indices into clinical practice to facilitate personalized treatment strategies and early diagnosis, enhancing the prognosis and survival in CRC.

Background: Current prediction models are suboptimal for determining mortality risk in patients with acute pancreatitis (AP); this might be improved by using a machine learning (ML) model. In this study, we aimed to construct an explainable ML model to calculate the risk of mortality in patients with AP admitted in intensive care unit (ICU) and compared it with existing scoring systems.

Methods: A gradient-boosting ML (XGBoost) model was developed and externally validated based on two public databases: Medical Information Mart for Intensive Care (MIMIC, training cohort) and the eICU Collaborative Research Database (eICU-CRD, validation cohort). We compared the performance of the XGBoost model with validated clinical risk scoring systems (the APACHE IV, SOFA, and Bedside Index for Severity in Acute Pancreatitis [BISAP]) by area under receiver operating characteristic curve (AUC) analysis. SHAP (SHapley Additive exPlanations) method was applied to provide the explanation behind the prediction outcome.

Results: The XGBoost model performed better than the clinical scoring systems in correctly predicting mortality risk of AP patients, achieving an AUC of 0.89 (95% CI: 0.84-0.94). When set the sensitivity at 100% for death prediction, the model had a specificity of 38%, much higher than the APACHE IV, SOFA and BISAP score, which had a specificity of 1%, 16% and 1% respectively.

Conclusions: This model might increase identification of very low-risk patients who can be safely monitored in a general ward for management. By making the model explainable, physicians would be able to better understand the reasoning behind the prediction.

Background: The role of ciprofol as a novel anesthetic in gastrointestinal endoscopic surgery is unclear. We conducted a systematic review and meta-analysis to evaluate the efficacy and safety of ciprofol for gastrointestinal endoscopy in patients aged over 65 years and under 65 years, aiming to provide evidence-based information for clinical decision-making.

Methods: We conducted a search for RCTs(randomized controlled trials) comparing ciprofol and propofol in gastrointestinal endoscopy on databases including PubMed, Embase, Cochrane Library, Web of Science, (China National Knowledge Infrastructure)CNKI, Wanfang, and Vipro Chinese Journal Service up to September 15, 2024. The required information was screened and extracted, and the quality of the included research literatures was assessed using the Cochrane Collaboration risk of bias assessment tool, and Meta-analysis of outcome metrics was performed using Revman 5.4 and Stata software.

Results: A total of 17 RCTs involving 2800 patients were included, with 1,450 patients in the ciprofol group and 1350 patients in the propofol group. The results of the meta-analysis indicated that there was no statistically significant difference in the sedation success rate or recovery time between the two groups across all age categories. In patients under 65 years old, the induction time of the ciprofol group (MD = 0.41 min, 95%CI: 0.04 min ∼ 0.78 min, P = 0.03) was longer than that in the propofol group. The incidences of hypotension (OR = 0.48, 95%CI: 0.32 ∼ 0.72, P = 0.004), bradycardia (OR = 0.66, 95%CI: 0.49 ∼ 0.87, P = 0.004), injection pain (OR = 0.08, 95%CI: 0.05 ∼ 0.15, P<0.0001), respiratory depression (OR = 0.21, 95%CI: 0.15 ∼ 0.30, P<0.0001), and hypoxemia (OR = 0.29, 95%CI: 0.20 ∼ 0.43, P<0.0001), in the ciprofol group were much lower than those in the propofol group.

Conclusion: Meta-analysis results indicate that, across various age groups, ciprofol demonstrates a higher safety profile and effectively reduces the incidence of postoperative (ADRs)adverse reactions compared to propofol. However, there is no significant difference in the sedative effects of the two agents. This study categorized elderly patients into subgroups, thereby providing a foundation for the application of ciprofol in gastrointestinal examinations of elderly patients. Consequently, we propose that ciprofol may serve as a safer alternative to intravenous anesthesia compared to propofol; However, this conclusion requires further validation through high-quality studies.

Background: Various oral manifestations are associated with coeliac disease in children, whereas data on adults are scarce. Moreover, possible individual factors predisposing to these manifestations remain unresolved. The aim of this study was to investigate these issues in a large cohort of adult coeliac disease patients both at diagnosis and while on gluten-free diet (GFD).

Methods: This population-based study involved 873 adult patients with coeliac disease and 563 non-coeliac controls. Patients and controls were interviewed and structured questionnaires were used to assess the severity of gastrointestinal symptoms and quality of life at the time of the study. All participants were systematically asked about oral manifestations, including dental enamel defects, recurrent aphthous ulceration and glossodynia. Coeliac disease-related data were collected from medical records. Possible individual factors associated with oral manifestations were studied using logistic regression analysis.

Results: Dental enamel defects were more common among patients than among non-coeliac controls (27% vs. 4%, p < 0.001). Prior to the coeliac disease diagnosis, 56% of the patients had experienced recurrent aphthous ulceration and GFD brought relief to 69% of them. While on GFD, coeliac disease patients had higher prevalence of recurrent aphthous ulceration than did the controls (17% vs. 13%, p = 0.040), but this significance disappeared after adjusting for gender. Glossodynia on GFD was more prevalent in the coeliac cohort than in the controls (14% vs 6%, p < 0.001). Oral manifestations at diagnosis and on GFD were associated with the presence of abdominal symptoms at the time of coeliac disease diagnosis, long diagnostic delay and female gender. At the time of the study, patients with oral symptoms had more severe gastrointestinal symptoms and poorer quality of life than those without these symptoms.

Conclusions: Oral manifestations were more prevalent, at diagnosis and on GFD, in patients with coeliac disease than in the controls, and they were associated with long diagnostic delay, abdominal symptoms, female gender and impaired quality of life. A GFD was shown beneficial in relieving recurrent aphthous ulcerations in patients with coeliac disease.

Background: coeliac disease (CD) is an inflammatory condition of the small intestine caused by immunological intolerance towards dietary gluten. Associations between CD and other autoimmune disorders have been extensively reported. However, the risk in CD patients of developing immune-mediated renal diseases (IMRDs) as a function of the duration of exposure to gluten remains uncharacterized.

Methods: we used data from the Swedish national patient register to retrospectively construct two subcohorts of CD patients by either years before or after CD diagnosis, matched by sex and age to reference individuals (ratio 1:6). Adopting cox regressions, we assessed the risk in CD to develop IMRDs.

Results: we found that unrecognized CD patients had a higher risk to develop the majority of the IMRDs here investigated compared with matched reference individuals. Following a CD diagnosis, the risk was reduced in eight of the twelve IMRDs. Furthermore, if patients were diagnosed with CD earlier in childhood they showed less or no increased risk to develop IMRDs compared with reference individuals. CD patients diagnosed by the age of 15 had an overall 12% increased risk of developing any IMRD, (HR: 1.12; CI = 1.02, 1.24; p < 0.02), as those with a CD diagnosis between 16 and 30 years of age had a 60% increased risk of developing IMRD (HR: 1.61; CI = 1.36, 1.91; p < 0.001).

Conclusions: Our data show that individuals diagnosed with CD at an earlier age have a lower risk of developing immune-mediated kidney conditions.

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.

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.

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.
