Objective: To evaluate and compare the efficacy and safety of Endoscopic Nasobiliary Drainage (ENBD) and Percutaneous Transhepatic Cholangiography Drainage (PTCD) in patients with advanced Hilar Cholangiocarcinoma (HCCA) through a meta-analysis of clinical studies.
Methods: We searched Chinese and English databases, including China National Knowledge Infrastructure (CNKI), Wanfang database, PubMed, Embase, Scopus, and Web of Science, for relevant literatures on PTCD and ENBD for advanced HCCA clinical trials. Two investigators independently screened the literatures, and the quality of the included studies was evaluated using the Newcastle-Ottawa Scale (NOS). The primary endpoint was the success rate of biliary drainage operation, while secondary endpoints included Total Bilirubin (TBIL) change, acute pancreatitis, biliary tract infection, hemobilia, and other complications. R software was used for data analysis.
Results: A comprehensive database search, based on predefined inclusion and exclusion criteria, yielded 26 articles for this study. Analysis revealed that PTCD had a significantly higher success rate than ENBD [OR (95% CI) = 2.63 (1.98, 3.49), Z=6.70, P<0.05]. PTCD was also more effective in reducing TBIL levels post-drainage [SMD (95%CI) =-0.13 (-0.23, -0.03), Z=-2.61, P<0.05]. While ENBD demonstrated a lower overall complication rate [OR (95%CI) = 0.60 (0.43, 0.84), Z=-2.99, P<0.05], it was associated with a significantly lower incidence of post-drainage biliary hemorrhage compared to PTCD [OR=3.02, 95%CI: (1.94-4.71), Z= 4.89, P<0.01].
Conclusions: This meta-analysis compares the efficacy and safety of ENBD and PTCD for palliative treatment of advanced HCCA. While both are effective, PTCD showed superiority in achieving successful drainage, reducing TBIL, and lowering the incidence of acute pancreatitis and biliary infections. However, ENBD had a lower risk of post-drainage bleeding. Clinicians should weigh these risks and benefits when choosing between ENBD and PTCD for individual patients. Further research is needed to confirm these findings and explore long-term outcomes.
Background: Gastroesophageal reflux disease (GERD) and cholecystitis share overlapping symptoms, including belching, acid reflux, and heartburn. Despite this, the causal relationship between these two conditions remains unclear. This study aimed to investigate the causal link between GERD and cholecystitis using a Mendelian randomization (MR) approach.
Methods: A two-sample MR analysis was conducted using the inverse variance weighted (IVW), weighted median, weighted mode, and MR-Egger method to assess the causal effects of GERD on the cholecystitis risk. Genome-wide association studies (GWASs) on GERD (N cases = 129080; N controls = 473524) and cholecystitis (N cases = 1930; N controls =359264) were obtained from the IEU Open GWAS project. Various techniques were employed to assess pleiotropy and heterogeneity.
Results: Seventy-seven single nucleotide polymorphisms from GERD GWASs were selected as instrumental variables (IVs). The primary IVW method revealed a significant association between GERD and an increased risk of cholecystitis (odds ratio = 1.004; 95% confidence interval = 1.003-1.005, p = 2.68 × 10- 9). The absence of heterogeneity and pleiotropy in the data supports the reliability of the results.
Conclusions: GERD was positively associated with the risk of cholecystitis. This study provides insights into potential avenues for the development of prevention strategies and treatment options for cholecystitis in patients with GERD. These findings contribute to our understanding of the complex interplay between GERD and cholecystitis.
Background: The neutrophil-to-high-density lipoprotein cholesterol ratio (NHR) has emerged as a promising biomarker for assessing inflammation and lipid dysregulation. Increasing evidence indicates that these metabolic disturbances play a crucial role in the development of metabolic dysfunction-associated steatotic liver disease(MASLD). This study aims to investigate the association between NHR, MASLD, and liver fibrosis.
Methods: This cross-sectional study analyzed data from the 2017-2020 National Health and Nutrition Examination Survey (NHANES). Weighted multivariate logistic regression models were used to investigate the association between NHR and both MASLD and liver fibrosis. Smoothed curve fitting and threshold effect analysis were performed to detect potential nonlinear relationships. Subgroup analyses were conducted to assess the consistency of these associations across different groups.
Results: The study involved 4,761 participants. We observed a significant positive association between NHR and MASLD (OR = 1.20, 95% CI: 1.09-1.31). However, there was no significant association between NHR and liver fibrosis (OR = 1.01; 95% CI: 0.94-1.09). The analysis of smoothed curve fitting and threshold effect revealed an inverted U-shaped relationship between NHR and MASLD, with a turning point at 5.63.
Conclusion: Our findings indicate a positive correlation between elevated NHR levels and MASLD prevalence. However, we did not observe a significant association between NHR and liver fibrosis prevalence. Further prospective research is needed to validate these findings in a longitudinal setting.
Background: Increasing evidences suggest that nonalcoholic fatty liver disease (NAFLD) is associated with neuropsychiatric disorders. Nevertheless, whether there were causal associations between them remained vague. A causal association between neuropsychiatric disorders and NAFLD was investigated in this study.
Methods: We assessed the published genome-wide association study summary statistics for NAFLD, seven mental disorder-related diseases and six central nervous system dysfunction-related diseases. The causal relationships were first assessed using two-sample and multivariable Mendelian randomization (MR). Then, sensitivity analyses were performed, followed by a reverse MR analysis to determine whether reverse causality is possible. Finally, we performed replication analyses and combined the findings from the above studies.
Results: Our meta-analysis results showed NAFLD significantly increased the risk of anxiety disorders (OR = 1.016, 95% CI = 1.010-1.021, P value < 0.0001). In addition, major depressive disorder was the potential risk factor for NAFLD (OR = 1.233, 95% CI = 1.063-1.430, P value = 0.006). Multivariable MR analysis showed that the causal effect of major depressive disorder on NAFLD remained significant after considering body mass index, but the association disappeared after adjusting for the effect of waist circumference. Furthermore, other neuropsychiatric disorders and NAFLD were not found to be causally related.
Conclusions: These results implied causal relationships of NAFLD with anxiety disorders and Major Depressive Disorder. This study highlighted the need to recognize and understand the connection between neuropsychiatric disorders and NAFLD to prevent the development of related diseases.
Background: Irritable bowel syndrome (IBS) is a common disease with unknown etiology. Poor dietary intake with nutritional deficiency and overweight have been described to increase the risk of IBS. The aim of the present study was to compare weight and circulating levels of micronutrients in IBS compared with healthy controls.
Design: Cross-sectional study.
Methods: Patients diagnosed with IBS and healthy volunteers were recruited. Participants had to complete a dietary diary book and the questionnaires Rome IV, IBS-severity scoring system (IBS-SSS), and visual analog scale for IBS (VAS-IBS). Weight and height were measured, and blood samples were drawn. C-reactive protein (CRP), cobalamin, folate, iron, total iron-binding capacity (TIBC), and 25-hydroxy (25-OH) vitamin D were analyzed. Differences were calculated between groups and generalized linear model for regressions was adjusted for false discovery rate (FDR).
Results: IBS patients (n = 260) were elder than controls (n = 50) (44.00 (33.25-56.00) vs. 37.85 (30.18-45.48) years; p = 0.012). After adjustment for age, both weight (β: 5.880; 95% CI: 1.433-10.327; p = 0.010, FDR = 0.020) and body mass index (BMI) (β: 2.02; 95% CI: 0.68-3.36; p = 0.003, FDR = 0.012) were higher in patients. Among IBS participants, 48.1% were overweight/obese compared with 26.0% in controls (p = 0.007). Diarrhea-predominated IBS had highest weight (p < 0.001) and BMI (p = 0.077). CRP and cobalamin were higher in patients than controls (p = 0.010 vs. p = 0.007), whereas folate was highest in controls (p = 0.001). IBS patients had lower intake of vegetables (p = 0.026), dairy products (p = 0.004), and cereals (p = 0.010) compared with controls. Despite 21.5% of IBS patients were taking vitamin D supplements, 23.65% of them had vitamin D levels below 50 nmol/L, compared with 26.0% observed in the control group (p = 0.720). Vitamin D levels were lower in overweight than in normal weight IBS patients (60 (48-73) nmol/L vs. 65 (53-78) nmol/L, p = 0.022). Vitamin D correlated with cobalamin and folate but correlated inversely with TIBC and BMI. IBS patients had a high degree of gastrointestinal and extraintestinal symptoms, which were inversely associated with iron levels. Extraintestinal symptoms were associated with increased BMI.
Conclusion: IBS patients were often overweight or obese, with low vitamin D levels. High burden of extraintestinal symptoms were associated with overweight and lower iron levels.

Background: Pyogenic liver abscess (PLA) caused by Klebsiella pneumoniae can vary in severity, and several risk factors for the development of organ dysfunction in PLA have been implicated. However, few studies to date have explored the most common risk factors for clinical severity.
Methods: We conducted a study on patients with PLA caused by Klebsiella pneumoniae between February 2013 and December 2022.Using logistic regression analysis, we sought to identify factors associated with positive blood culture, septic shock, and intensive care unit (ICU) admission.
Results: After included 200 patients, we found that an elevated procalcitonin (PCT) level (p = 0.03), higher glucose level (p = 0.03), and lower total cholesterol (TC) level (p = 0.01) were associated with a higher likelihood of positive blood bacteriological culture. Additionally, an increased PCT level (p = 0.02) and lower TC level (p < 0.01) were associated with an elevated risk of septic shock. Furthermore, a higher PCT level (p < 0.01) was associated with a higher probability of ICU admission.
Conclusion: In patients with PLA caused by Klebsiella pneumoniae, the PCT, glucose, and TC levels were found to be associated with positive blood culture, septic shock, and ICU admission.
Background: Pembrolizumab plus cisplatin and 5-fluorouracil administered as first-line therapy for advanced esophageal cancer patients has shown a better objective response and survival than conventional chemotherapy with less severe hematological adverse events. The safety and efficacy of this regimen were evaluated in patients with T4b esophageal squamous cell carcinoma (ESCC).
Methods: Eight consecutive patients with T4b ESCC received this regimen according to KEYNOTE-590 as induction, and they were evaluated after 1-3 courses. The programmed death-ligand 1 (PD-L1) combined positive score (CPS) was also evaluated before chemotherapy. Efficacy for the primary lesion was evaluated by our original formula for the tumor reduction rate.
Results: The numbers of patients with partial response (PR), stable disease, and progressive disease (PD) were 5, 1, and 2, respectively. The tumor reduction rate ranged from 69 to 87% in PR patients, and all PR patients had relief from T4b. Two patients underwent conversion surgery with R0 resection. PD-L1 CPS was over 90 in 2 PR patients, but under 10 in 2 other PR patients. PD-L1 CPS was under 10 in PD patients. One patient had hyperprogression, resulting in an esophago-pulmonary fistula. Greater than grade 3 adverse events were bleeding gastric ulcer in one patient (12.5%), neutropenia without G-CSF in 3 patients (37.5%), and hypopotassemia in 1 patient (12.5%). No patient had febrile neutropenia.
Conclusions: Marked tumor reduction was confirmed in 62.5% of patients with pembrolizumab plus cisplatin and 5-fluorouracil with less adverse events. This regimen could be administered as induction chemotherapy for patients with T4b ESCC.
Background: An association has been observed between primary biliary cholangitis (PBC) and systemic rheumatic diseases (SRDs) in observational studies, however the exact causal link remains unclear. We aimed to evaluate the causal effects of PBC on SRDs through Mendelian randomization (MR) analysis.
Methods: The genome-wide association study (GWAS) summary data were obtained from MRC IEU OpenGWAS and FinnGen databases. Independent genetic variants for PBC were selected as instrumental variables. Inverse variance weighted was used as the main approach to evaluate the causal effects of PBC on Sjögren syndrome (SS), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), systemic sclerosis (SSc), mixed connective tissue disease (MCTD) and polymyositis (PM). Horizontal pleiotropy and heterogeneity were measured by MR‒Egger intercept test and Cochran's Q value, respectively.
Results: PBC had causal effects on SS (OR = 1.177, P = 8.02e-09), RA (OR = 1.071, P = 9.80e-04), SLE (OR = 1.447, P = 1.04e-09), SSc (OR = 1.399, P = 2.52e-04), MCTD (OR = 1.306, P = 4.92e-14), and PM (OR = 1.416, P = 1.16e-04). Based on the MR‒Egger intercept tests, horizontal pleiotropy was absent (all P values > 0.05). The robustness of our results was further enhanced by the leave-one-out method.
Conclusions: Our research has provided new insights into PBC and SRDs, indicating casual effects on various SRDs.
