Abstract
INTRODUCTION Esophageal foreign bodies are often treated by endoscopy, but the treatment of esophageal perforation caused by foreign bodies remains controversial. The purpose of this study was to investigate the safety and efficacy of nonoperative treatment of esophageal perforation caused by foreign bodies. METHODS We retrospectively analyzed 270 patients admitted to our hospital for esophageal perforation caused by foreign bodies from January 2012 to December 2020, all of whom received nonoperative treatment. RESULTS The mean age of the patients was 56 ± 17 years, and fish bones were the most common type of foreign body. A total of 61.2% of the perforations were in the cervical esophagus. All patients received nonoperative treatment initially, and the foreign body removal rate using endoscopy reached 97%. The perforation healing rate reached 94.8%, whereas 3 patients (1.1%) died during hospitalization. The median (range) duration of hospitalization was 4 days (3-6). Multivariable analysis showed age ≥ 66 years (odds ratio [OR]: 2.196; 95% confidence interval [CI]: 1.232-3.916; P = 0.008), men (OR: 1.934; 95% CI: 1.152-3.246; P = 0.013), and time to treatment (OR: 1.126; 95% CI: 1.027-1.233; P = 0.011) were independent risk factors for infection, whereas the risk of infection was lower when the foreign body type was fish bone (OR: 0.557; 95% CI: 0.330-0.940; P = 0.028). DISCUSSION Nonoperative treatment is safe and effective for esophageal perforation caused by foreign bodies. Even if perforation is combined with infection, active nonoperative treatment can still achieve a good effect. Early intervention can effectively reduce the risk of infection and improve patient outcomes.

Abstract
BACKGROUND Although metal stents have been widely used in the endoscopic step-up approach for necrotizing pancreatitis, the exact timing of transmural stent removal has not been well studied. Here, we report a novel strategy for stent removal and compare it with the conventional strategy. MATERIALS AND METHODS This retrospective, nested, case-control study analyzed all adult necrotizing pancreatitis patients who underwent endoscopic transmural necrosectomy (ETN). Clinical outcomes were compared between case group (a novel strategy in which the stents were removed during the last necrosectomy when the ETN endpoint was achieved) and 1:1 necrosis extent matched control group (the conventional strategy). RESULTS Baseline characteristics was comparable between case group (n=37) and control group (n=37). Three (8.1%) patients in case group and 1 (2.7%) patient in control group needed additional ETN after stent removal (P>0.05). Nearly all patients (case: 97.3%; control: 94.6%) achieved clinical success. There was no difference in disease-related (case: 40.5%; control: 37.8%) or stent-related (case: 27.0%; control: 16.2%) complications. Case group had a trend of shorter length of stent placement (median: 20.0 vs. 29.5 d, P>0.05). CONCLUSIONS The novel strategy of transmural stent removal during last necrosectomy might be feasible which needed further validation. Compared with the convention strategy, the novel strategy avoids one endoscopy procedure and should be considered in clinical practice.

Abstract
The aim of the current systematic review was to summarize and to evaluate the available information on the effectiveness of oral exercise in improving the masticatory function of people ≥18 y. Electronic databases (Medline, Embase, CENTRAL) and gray literatures were searched (up to December 2020) for relevant randomized and nonrandomized controlled clinical trials. Two reviewers independently conducted the study selection, data extraction, and quality assessments. Meta-analysis was conducted for the comparison of bite force and masticatory performance using mean difference (MD) and standardized mean difference (SMD), respectively. GRADE (Grading of Recommendations Assessment, Development, and Evaluation) assessment was adopted for collective grading of the overall body of evidence. Of the 1,576 records identified, 18 studies (21 articles) were included in the analysis. Results of meta-analysis indicated that oral exercise could significantly improve the mean bite force of the participants (parallel comparison: MD, 41.2; 95% CI, 11.6-70.7, P = 0.006; longitudinal comparison: MD, 126.5; 95% CI, 105.2-144.9, P < 0.001). However, the improvement in masticatory performance was not significant (parallel comparison: SMD, 0.11; 95% CI, -0.20 to 0.42, P = 0.48; longitudinal comparison: SMD, 0.4; 95% CI, -0.11 to 0.91, P = 0.13). Results of meta-regression showed that greater improvements in bite force can be achieved among younger adults and with more intensive exercise. Chewing exercise is the most effective oral exercise, followed by clenching exercise, while simple oral exercise may not have a significant effect. Based on the results of the meta-analysis and GRADE assessment, a weak recommendation for people with declined masticatory function to practice oral exercise is made.

Abstract
Renal cell carcinoma (RCC) is the most common renal tumor with a high incidence in the recent decade. Generally, an RCC metastasis mainly occurs via hematogenous and lymphomatous routes. Even though RCC has a potential to metastasize to almost any site, metastasis to the pancreas and duodenal ampulla is a rare event. In this study, we describe a case of pancreatic and periampullary metastatic renal cell carcinoma, which recurred 17 years after surgery. The patient admitted to hospital for severe symptoms of jaundice and skin pruritus after removal of the primary tumor for 17 years. Computer tomography angiography (CTA) scan and endoscopy showed pancreatic and duodenal ampullary metastasis. Finally, it confirmed by histopathologic examination. After some symptomatic treatment has been given the patient remained alive. However, intermittent hematochezia along with these metastatic lesions continue to occur until now as observed during the annual follow-up appointments. This study concludes that metastatic involvement of the pancreas and other organs should be suspected in any patient with a history of an RCC who does not manifest any typical symptom even after more than 10 years of RCC resection. In the case of abnormal symptoms and examination results after several years of RCC surgery, attention should be paid to provide immediate treatment.

BMJ Open Respir Res 2021; 8:8/1/e000819. [PMID: 34452934 PMCID: PMC8404447 DOI: 10.1136/bmjresp-2020-000819] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Accepted: 07/11/2021] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND Despite currently available standard-of-care inhaled corticosteroid (ICS)/long-acting β2-agonist therapies, a substantial proportion of patients with asthma remain inadequately controlled. This pooled analysis evaluated efficacy and safety of mometasone furoate/indacaterol acetate (MF/IND) versus fluticasone propionate/salmeterol xinafoate (FLU/SAL) in patients with inadequately controlled asthma. METHODS This analysis included patients from PALLADIUM (NCT02554786) and IRIDIUM (NCT02571777) studies who received high-dose MF/IND (320/150 µg) or medium-dose MF/IND (160/150 µg) one time a day or high-dose FLU/SAL (500/50 µg) two times a day for 52 weeks. Reduction in asthma exacerbations, improvement in lung function, asthma control, and safety were evaluated for 52 weeks. RESULTS In total, 3154 patients (high-dose MF/IND, n=1054; medium-dose MF/IND, n=1044; high-dose FLU/SAL, n=1056) were included. High-dose MF/IND showed 26%, 22% and 19% reductions in rate of severe, moderate or severe, and all (mild, moderate and severe) exacerbations versus high-dose FLU/SAL, respectively, over 52 weeks (all, p<0.05). High-dose MF/IND improved trough FEV1 versus high-dose FLU/SAL at weeks 26 (Δ, 43 mL, p=0.001) and 52 (Δ, 51 mL, p<0.001). Reductions in asthma exacerbation rate and improvement in trough FEV1 with medium-dose MF/IND were comparable with high-dose FLU/SAL over 52 weeks. All treatments improved Asthma Control Questionnaire-7 score from baseline to 52 weeks with no difference between treatments. Safety was comparable between high-dose MF/IND and high-dose FLU/SAL. CONCLUSIONS One time a day, single-inhaler, high-dose MF/IND reduced asthma exacerbations and improved lung function versus two times a day, high-dose FLU/SAL in patients with inadequately controlled asthma. Similarly, improved outcomes were seen with one time a day, medium-dose MF/IND and two times a day, high-dose FLU/SAL, but at a lower ICS dose.

Abstract
Background: Proton pump inhibitors (PPIs) are validated gastric acid suppressors and have been widely used to treat patients with active duodenal ulcers. Although existing PPIs have shown great efficacy, many scientists are still devoted to developing more effective PPIs with better safety profile. Herein, we aimed to compare the safety and efficacy of anaprazole in duodenal mucosal healing, a novel PPI, to that of rabeprazole. Methods: In this multicenter, randomized, positive-controlled, double-blinded, parallel-group phase II clinical trial, a total of 150 qualified patients with endoscopically confirmed active duodenal ulcers were randomized (1:1:1) to receive rabeprazole 10 mg, anaprazole 20 mg or anaprazole 40 mg for 4 weeks. The ulcer healing rates after 4 weeks of treatment were compared between groups by independent central review and investigator review. In addition, symptoms and safety were evaluated. Results: Based on the independent central review, the ulcer healing rates of the 10 mg rabeprazole, 20 mg anaprazole and 40 mg anaprazole groups were 88.0, 85.1, and 87.5%, respectively, in the FAS population and 88.9, 86.0, and 90.9%, respectively, in the PPS population. The ulcer healing rate difference between anaprazole 20 mg and Rabeprazole 10 mg is −2.9% (95% CI, −16.5–10.7%), and −0.5% (95% CI, −13.5–12.5%) between anaprazole 40 mg and Rabeprazole 10 mg, in the FAS population. Based on the investigator review, the ulcer healing rates of the 10 mg rabeprazole, 20 mg anaprazole, and 40 mg anaprazole groups were 72.0, 70.2, and 77.1%, respectively, in the FAS population and 75.6, 72.1, and 79.5%, respectively, in the PPS population. The ulcer healing rate difference between anaprazole 20 mg and Rabeprazole 10 mg is −1.8% (95% CI, −19.8–16.3%), and 5.1% (95% CI, −12.2–22.3%) between anaprazole 40 mg and Rabeprazole 10 mg, in the FAS population. Most patients (>90%) eventually achieved complete symptom relief. The incidence rates of adverse events were of no significant differences among the treatment groups. Potential possible better liver tolerance was observed in two anaprazole dose groups than rabeprazole 10 mg group. Conclusion: Both at a dosage of 20 and 40 mg daily, anaprazole, is effective with good safety profile in the treatment of active duodenal ulcers in this Phase 2 study, which allows anaprazole to be advanced to a phase III clinical trial.

Abstract
Intestinal tuberculosis (ITB) and Crohn's disease (CD) are chronic inflammatory bowel disorders that are associated with dysregulated mucosal immunity. The gut microbiota plays an important role in the regulation of host immunity and inflammatory response. Although mounting evidence has linked CD with the dysbiosis of gut microbiota, the characteristic profiles of mucosal bacteria in ITB remain unclear. The aim of this study was to assess the alterations of the gut microbiota in ITB and compare the microbial structure of ITB with CD. A total of 71 mucosal samples were collected from patients with ITB, CD, and healthy controls (HC), and then, 16S rRNA gene sequencing was performed. The overall composition of gut microbiota in ITB was strikingly different from HC, with the dominance of Proteobacteria and reduction of Firmicutes. Of note, the short-chain fatty acids (SCFAs)-producing bacteria such as Faecalibacterium, Roseburia, and Ruminococcus were decreased in ITB relative to HC, while Klebsiella and Pseudomonas were enriched. Multiple predictive functional modules were altered in ITB, including the over-representation of lipopolysaccharide biosynthesis, bacterial invasion of epithelial cells, and pathogenic Escherichia coli infection that can promote inflammation. Additionally, the microbial structure in CD was distinctly different from ITB, characterized by lower alpha diversity and increased abundance of Bacteroides, Faecalibacterium, Collinsella, and Klebsiella. These four bacterial markers distinguished ITB from CD with an area under the curve of 97.6%. This study established the compositional and functional perturbation of the gut microbiome in ITB and suggested the potential for using gut microbiota as biomarkers to differentiate ITB from CD.

Abstract
BACKGROUND AND STUDY AIMS This study was conducted to investigate the significance of tumor and biochemical markers in serum and ascitic fluid in the differential diagnosis of tuberculous and malignant ascites. PATIENTS AND METHODS Based on findings from natural orifice transluminal endoscopic surgery and postoperative pathology or cytology of 63 patients, they were divided into the malignant group (31 patients) and the tuberculous group (32 patients). Levels of tumor markers, albumin, globulin, and lactate dehydrogenase were measured simultaneously. Data were statistically analyzed, and a Fisher discriminant model was established. The receiver operating characteristic curve was constructed to confirm the discriminant value. RESULTS The levels of carcinoembryonic antigen (CEA), cancer antigen 125 (CA125), cancer antigen 19-9 (CA 19-9), and globulin in serum and ascitic fluid were different between the tuberculous and malignant ascites groups (P < .05). The ratios of ascites-to-serum levels of CEA, CA125, and CA 19-9, as well as the ratio of serum-to-ascites of globulin levels, were different between the two groups (P < .05). The Fisher discriminant model was established based on the ascites-to-serum ratios of CEA, CA125, and CA 19-9 levels and the serum-to-ascites ratio of globulin levels. The area under the curve was 0.908, the sensitivity was 0.838 (26/31), and the specificity was 0.875 (28/32). CONCLUSION A Fisher discriminant model can be established using serum and ascites tumor markers and globulin ratios, which is valuable in the differential diagnosis of tuberculous versus malignant ascites.

Abstract
Background Endoscopic submucosal dissection (ESD) and endoscopic submucosal excavation (ESE) have been widely used and have gradually become the main endoscopic treatment for gastrointestinal mucosal and submucosal lesions. Whether antibiotics are necessary for fever after gastric ESD and ESE remain unclear. The aim of this study was to analyse the value of using antibiotics in patients without perforation after ESD or ESE with fever. Methods In this retrospective study, patients with fever without perforation after ESD or ESE from January 2014 to January 2019 were included and divided into 2 groups: the antibiotic group and the non-antibiotic group. Fever and hospitalization time were compared between the 2 groups after propensity score matching. Results Overall, 253 patients meeting the inclusion criteria were enrolled in the present study, with 186 patients in the non-antibiotic group and 67 patients in the antibiotic group before matching, 55 patients in the non-antibiotic group and 55 patients in the antibiotic group after matching with all baseline characteristics balanced (p > 0.05). The duration of fever was not significantly different between the 2 groups (p = 0.12). However, the median hospitalization stay in the antibiotic group was longer than that in the non-antibiotic group (8 vs 7, p = 0.007). Conclusions Antibiotics may be unnecessary for fever in patients without perforation and without serious co-morbidities after gastric ESD or ESE.

Abstract
INTRODUCTION To define the best cutoff of the Glasgow-Blatchford score (GBS) for identifying high- and low-risk rebleeding patients with bleeding ulcers and high-risk stigmata after endoscopic hemostasis and compare the efficacy of high-dose and standard-dose intravenous proton pump inhibitors (HD-IVPs and SD-IVPs, respectively) in this patient population. METHODS We retrospectively reviewed the data of 346 patients with bleeding ulcers and high-risk stigmata who underwent endoscopic hemostasis between March 2014 and September 2018 in our center and were divided into an HD-IVP group and an SD-IVP group. Propensity score-matching analysis was performed to control for selection bias and other potential confounders. Recurrent bleeding rates were calculated according to the GBS. RESULTS Overall, 346 patients meeting the inclusion criteria were enrolled, with 89 patients in the SD-IVP group and 89 patients in the HD-IVP group after matching with all baseline characteristics balanced (P > 0.05). GBS = 8 was the best cutoff for identifying high-risk rebleeding patients (GBS ≥ 8) with a significant difference (P = 0.015) in recurrence rate between the SD-IVP (17/61, 27.9%) and HD-IVP (7/65, 10.8%) groups and low-risk rebleeding patients (GBS < 8) with no difference (P = 1) in recurrence rate between the SD-IVP (2/28, 7.1%) and HD-IVP (2/24, 8.3%) groups. DISCUSSION The best cutoff for identifying high-risk and low-risk rebleeding patients with bleeding ulcers and high-risk stigmata after endoscopic hemostasis was GBS = 8. Although HD-IVP is more effective than SD-IVP in high-risk patients, they are equally effective in low-risk patients.

Abstract
Helicobacter pylori (H. pylori) infection is the strongest known risk factor for the development of gastric cancer. DNA damage response (DDR) and autophagy play key roles in tumorigenic transformation. However, it remains unclear how H. pylori modulate DDR and autophagy in gastric carcinogenesis. Here we report that H. pylori infection promotes DNA damage via suppression of Rad51 expression through inhibition of autophagy and accumulation of p62 in gastric carcinogenesis. We find that H. pylori activated DNA damage pathway in concert with downregulation of repair protein Rad51 in gastric cells, C57BL/6 mice and Mongolian gerbils. In addition, autophagy was increased early and then decreased gradually during the duration of H. pylori infection in vitro in a CagA-dependent manner. Moreover, loss of autophagy led to promotion of DNA damage in H. pylori-infected cells. Furthermore, knockdown of autophagic substrate p62 upregulated Rad51 expression, and p62 promoted Rad51 ubiquitination via the direct interaction of its UBA domain. Finally, H. pylori infection was associated with elevated levels of p62 in gastric intestinal metaplasia and decreased levels of Rad51 in dysplasia compared to their H. pylori- counterparts. Our findings provide a novel mechanism into the linkage of H. pylori infection, autophagy, DNA damage and gastric tumorigenesis.

Abstract
Early dysbiosis of the gut microbiota is associated with the severity of acute pancreatitis (AP), although the underlying mechanism is unclear. Here, we investigated the role of crosstalk between NLRP3 and the gut microbiota in the development of AP utilizing gut microbiota deficient mice, as well as NLRP3 knockout (KO) mouse models. Pancreatic damage and systemic inflammation were improved in antibiotic-treated (Abx) and germ-free (GF) mice, accompanied by weakened activity of the intestinal NLRP3 inflammasome. Interestingly, fecal microbiota transplantation (FMT) reactivated the intestinal NLRP3 inflammasome and exacerbated the disease in Abx and GF mice. Although the gut barrier in GF and Abx mice was disrupted, gut microbiota deficiency ameliorated the severity of AP, probably due to the reduction in bacterial translocation from the gut to the pancreas. The composition of the gut microbiota was significantly different between NLRP3 KO mice and wild-type (WT) mice at baseline, and there were alterations in response to the induction of AP. While a dramatic shift in the gut microbiota with overgrowth of Escherichia-Shigella was observed in WT mice suffering from AP, there was no significant change in NLRP3 KO mice with or without AP, suggesting that NLRP3 deficiency counteracts AP-induced microbial disturbance. With a strengthened gut barrier and decreased systemic inflammation, NLRP3 KO mice showed less severe AP, as revealed by reduced pancreatic neutrophilic infiltration and necrosis. Taken together, these results identified the bidirectional modulation between the gut microbiota and NLRP3 in the progression of AP, which suggests the interplay of the host and microbiome during AP.

Abstract
Abstract
Background
Gene mutations have been implicated in DCM. However, due to the difficulty of clinical genetic diagnosis, more causal genes potentially related to DCM remain to be discovered.
Methods
We screened for gene mutations in more than 400 cases from families with hereditary cardiovascular disease using whole-exome sequencing. Then we validated biological functions of CHMP4C mutations in zebrafish models. To further assess the mechanism of CHMP4C mutations, we evaluated the potential signaling pathway in the cells.
Results
We identification of CHMP4C variants that segregated with DCM variants in four families from a total of 411 families via whole-exome sequencing. We further validate the function of CHMP4C in heart function in zebrafish models and found that over-expression of CHMP4C variants in zebrafish resulted in cardiac malformation, pericardial edema and increased heart rate, consistent with CHMP4C mutation-associated findings in DCM patients. Furthermore, we found that mutations in CHMP4C impaired autophagy and activated apoptosis in HEK293T cells, suggesting that the molecular mechanism of CHMP4C is involved in heart development.
Conclusions
CHMP4C is a novel candidate gene for DCM and may play a critical role in cardiac development by regulating autophagy.

Abstract
Abstract
Background
Non-invasive left ventricular (LV) pressure-strain loops (PSLs) which generated by combining LV longitudinal strain with brachial artery blood pressure, provide a novel method of quantifying global and segmental myocardial work (MW) indices with potential advantages over conventional echocardiographic strain which is load-dependent. The method has been introduced in echocardiographic software recently, making MW calculations more effectively and rapidly. The aim was to evaluate the role of non-invasive MW indices derived from LV PSLs in the prediction of cardiac resynchronization therapy (CRT) response.
Methods
106 heart failure (HF) patients scheduled for CRT were included for MW analysis. Global and segmental (septal and lateral at the mid-ventricular level) MW indices were accessed before CRT. Response to CRT was defined as ≥15% reduction in LV end-systolic volume at 6-month follow-up in comparison with baseline value.
Results
CRT response was observed in 78 (74%) patients. At baseline, global work index (GWI) and global constructive work (GCW) were significant higher in CRT responders than in non-responders (both P<0.05). Besides, responders exhibited a significantly higher Mid Lateral MW and Mid Lateral constructive work (CW) (both P<0.001) but a significantly lower Mid Septal MW and Mid Septal myocardial work efficiency (MWE), as well as a significantly higher Mid Septal wasted work (WW) than non-responders (all P<0.01). Baseline Mid Septal MWE (OR 0.975, 95% CI 0.959–0.990, P=0.002) and Mid Lateral MW (OR 1.003, 95% CI 1.002–1.004, P<0.001) were identified as independent predictors of CRT response in multivariate regression analysis. Mid Septal MWE ≤42% combined with Mid Lateral MW ≥740 mm Hg% predicted CRT response with the optimal sensitivity of 79% and specificity of 82% (AUC = 0.830, P<0.001).
Conclusion
Mid Septal MWE and Mid Lateral MW can successfully predict response to CRT, and their combination can further improve the prediction accuracy. Assessment of MW indices before CRT could identify the marked misbalance in LV myocardial work distribution and has the potential to be widely used as a reliable complementary tool for guiding patient selection in clinical practice.

Abstract
RATIONALE Non-variceal gastrointestinal bleeding is a common critical disease worldwide, and according to relevant guidelines, surgery and interventional treatment are the final therapies. However, few studies have reported on therapeutic strategies to employ when the ultimate treatment fails. This report offers a reasonable option for hemostasis after surgery and interventional treatment both fail. PATIENT CONCERNS A 47-year-old man with recurrent bleeding had undergone endoscopy, surgery, and interventional therapy; however, effective hemostasis was not achieved. DIAGNOSIS This patient's clinical manifestations and typical gastroscopic findings confirmed duodenal bulb ulcer with hemorrhage INTERVENTIONS:: A Billroth II + Bancroft operation, interventional treatment, and endoscopic hemostasis with an over-the-scope clip (OTSC) system were administered. OUTCOMES The bleeding was successfully controlled, and the patient remained well during long-term follow-up. LESSONS The OTSC system can represent a reasonable option for ulcer hemostasis after surgery when other interventional therapies have failed.

Abstract
AIM AND OBJECTIVE Fatty acid desaturase 1 (FADS1) has been reported to be a potential biomarker in various cancers. However, no study has explored the relationship between FADS1 expression and bladder cancer. Our study aimed to investigate the role of FADS1 in bladder cancer prognosis via The Cancer Genome Atlas (TCGA). MATERIALS AND METHODS RNA-Seq expression of 414 tumor tissues and 19 paired normal tissues, as well as corresponding clinical data, were downloaded from the TCGA database. Two cancer cases were excluded due to a lack of clinical information. The association between FADS1 and the clinicopathological features of bladder cancer was analyzed. This study was conducted in October 2019 in China. RESULTS The high expression of FADS1 in bladder cancer was significantly related to histological grade (OR = 0.155 for low vs. high), clinical stage (OR=2.074 for III or IV vs. I or II), T classification (OR=2.326 for T3 or T4 vs. T1 or T2), lymphatic metastasis (OR=1.923 for N1 or N2 or N3 vs. N0) and distant metastasis (OR=4.883 for yes vs. no) (all p-values <0.05). Bladder cancer with high FADS1 levels was related to a worse prognosis than bladder cancer with low FADS1 levels (p= 1.626*10-5), according to median expression value 3.622. FADS1 was an independent factor of overall survival in bladder cancer, with a hazard ratio of 1.048 (95%CI: 1.020-1.077, p = 0.001). CONCLUSION Increased FADS1 expression in bladder cancer is associated with advanced clinicopathological features and may be a potential biomarker for poor prognosis.

Abstract
Addressing pancreaticobiliary disorders concomitant with gastroesophageal varices remains challenging. The goal of this study was to evaluate and compare the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) in cirrhotic and noncirrhotic patients with gastroesophageal varices.We retrospectively analyzed the data of consecutive patients with gastroesophageal varices who underwent ERCP.Two hundred seventy ERCP procedures were performed on 208 patients. The overall technical success rate was 98.5%, and no difference was found between cirrhotic and noncirrhotic patients (98.7% vs 97.7%, P = .511); of these, endoscopic retrograde biliary drainage, endoscopic metal biliary endoprosthesis placement, endoscopic retrograde pancreatic drainage, and stone extraction were conducted in 173/270 (64.1%), 27/270 (10.0%), 26/270 (9.6%), and 116/270 (43.0%) cases, respectively. Endoscopic retrograde biliary drainage and stone extraction were more frequently performed in cirrhotic cases (67.7% versus 45.5%, P = .005; 46.5% versus 25.0%, P = .009, respectively), while the noncirrhotic group had significantly higher rates of endoscopic metal biliary endoprosthesis placement (31.8% versus 5.8%, P = .000) and endoscopic retrograde pancreatic drainage (18.2% versus 8.0%, P = .036) than the cirrhotic group. The overall rate of adverse events was 21.1%, including fever (6.7%), post-ERCP pancreatitis ( 3.0%), hyperamylasemia (6.3%), duodenal papilla bleeding (3.3%), cardiac mucosal laceration (1.1%), and perforation (0.4%). No differences in any of the adverse events were found between the 2 groups. Additionally, gastroesophageal variceal bleeding occurred in 1 patient with grade III varices 7 days after ERCP.ERCP may be effective and safe for patients with gastroesophageal varices, irrespective of the etiologies caused by liver cirrhosis.

THE LANCET RESPIRATORY MEDICINE 2020; 8:987-999. [PMID: 32653075 DOI: 10.1016/s2213-2600(20)30178-8] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Revised: 03/24/2020] [Accepted: 04/09/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Fixed-dose combinations (FDCs) of inhaled corticosteroids (ICS) and long-acting β2-adrenoceptor agonists (LABA) are considered safe and efficacious in asthma management. Most available FDCs require twice-daily dosing to achieve optimum therapeutic effect. The objective of the PALLADIUM study was to assess the efficacy and safety of once-daily FDC of mometasone furoate plus indacaterol acetate (MF-IND) versus mometasone furoate (MF) monotherapy in patients with inadequately controlled asthma. METHODS This 52-week, double-blind, triple-dummy, parallel-group, phase 3 study recruited patients from 316 centres across 24 countries. Patients aged 12 to 75 years with a documented diagnosis of asthma for at least 1 year, percentage of predicted FEV1 of 50-85%, and an Asthma Control Questionnaire 7 score of at least 1·5 despite treatment with medium-dose or high-dose ICS or low-dose ICS plus LABA were included. A history of asthma exacerbations was not a study requirement. Participants were randomily assigned (1:1:1:1:1) via interactive response technology to receive one of the following treatments for 52 weeks: high-dose MF-IND (320 μg, 150 μg) or medium-dose MF-IND (160 μg, 150 μg) once daily via Breezhaler; high-dose MF (800 μg [400 μg twice daily]) or medium-dose MF (400 μg once daily) via Twisthaler; or high-dose fluticasone propionate-salmeterol xinafoate (FLU-SAL; 500 μg, 50 μg) twice daily via Diskus. Participants received placebo via inhalation through the Breezhaler, Twisthaler, or Diskus devices in the mornings and evenings, as appropriate. The primary endpoint was improvement in trough FEV1 with high-dose and medium-dose MF-IND versus respective MF doses from baseline at 26 weeks, analysed in the full analysis set by means of a mixed model for repeated measures. High-dose MF-IND once daily was compared with high-dose FLU-SAL twice daily for non-inferiority on improving trough FEV1 at week 26 with a margin of -90 mL using mixed model for repeated measures as one of the secondary endpoints. Safety was assessed in all patients who had received at least one dose of study drug. This study is registered with ClinicalTrials.gov, NCT02554786, and is completed. FINDINGS Between Dec 29, 2015, and May 4, 2018, 2216 patients were randomly assigned (high-dose MF-IND, n=445; medium-dose MF-IND, n=439; high-dose MF, n=442; medium-dose MF, n=444; high-dose FLU-SAL, n=446), of which 1973 (89·0%) completed the study treatment and 234 (10·6%) prematurely discontinued study treatment. High-dose MF-IND (treatment difference [Δ] 132 mL [95% CI 88 to 176]; p<0·001) and medium-dose MF-IND (Δ 211 mL [167 to 255]; p<0·001) showed superiority in improving trough FEV1 over corresponding MF doses from baseline at week 26. High-dose MF-IND was non-inferior to high-dose FLU-SAL in improving trough FEV1 from baseline at week 26 (Δ 36 mL [-7 to 80]; p=0·101). Overall, the incidence of adverse events was similar across the treatment groups. INTERPRETATION Once-daily FDC of ICS and LABA (MF-IND) significantly improved lung function over ICS monotherapy (MF) at week 26; high-dose MF-IND was non-inferior to twice-daily combination of ICS and LABA (high-dose FLU-SAL) for improvement in trough FEV1. The combination of MF-IND provides a novel once-daily dry powder option for asthma control. FUNDING Novartis Pharmaceuticals.

Abstract
BACKGROUND Patients with asthma who are inadequately controlled on inhaled corticosteroid-long-acting β2-adrenoceptor agonist (ICS-LABA) combinations might benefit from the addition of a long-acting muscarinic receptor antagonist. The aim of the IRIDIUM study was to assess the efficacy and safety of a once-daily, single-inhaler combination of mometasone furoate, indacaterol acetate, and glycopyrronium bromide (MF-IND-GLY) versus ICS-LABA in patients with inadequately controlled asthma. METHODS In this 52-week, double-blind, double-dummy, parallel-group, active-controlled phase 3 study, patients were recruited from 415 sites across 41 countries. Patients aged 18 to 75 years with symptomatic asthma despite treatment with medium-dose or high-dose ICS-LABA, at least one exacerbation in the previous year, and a percentage of predicted FEV1 of less than 80% were included. Enrolled patients were randomly assigned (1:1:1:1:1) via interactive response technology to receive medium-dose or high-dose MF-IND-GLY (80 μg, 150 μg, 50 μg; 160 μg, 150 μg, 50 μg) or MF-IND (160 μg, 150 μg; 320 μg, 150 μg) once daily via Breezhaler, or high-dose fluticasone-salmeterol (FLU-SAL; 500 μg, 50 μg) twice daily via Diskus. The primary outcome was change from baseline in trough FEV1 with MF-IND-GLY versus MF-IND at week 26 in patients in the full analysis set, analysed by means of a mixed model for repeated measures. Safety was assessed in all patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, NCT02571777, and is completed. FINDINGS Between Dec 8, 2015, and Jun 14, 2019, 3092 of 4851 patients screened were randomly assigned (medium-dose MF-IND-GLY, n=620; high-dose MF-IND-GLY, n=619; medium-dose MF-IND, n=617; high-dose MF-IND, n=618; high-dose FLU-SAL, n=618). 2747 (88·8%) patients completed the 52-week treatment and 321 (10·4%) started but discontinued study treatment prematurely. Medium-dose MF-IND-GLY (treatment difference [Δ] 76 mL [95% CI 41-111]; p<0·001) and high-dose MF-IND-GLY (Δ 65 mL [31-99]; p<0·001) showed superior improvement in trough FEV1 versus corresponding doses of MF-IND at week 26. Improvements in trough FEV1 were greater for both medium-dose MF-IND-GLY (99 mL [64-133]; p<0·001) and high-dose MF-IND-GLY (119 mL [85-154]; p<0·001) than for high-dose FLU-SAL at week 26. Overall, the incidence of adverse events was balanced across the treatment groups. Seven deaths were reported (one with medium-dose MF-IND-GLY, two with high-dose MF-IND-GLY, and four with high-dose MF-IND) during the study; none of these deaths was considered by the investigators to be caused by study drugs or other study-related factors. INTERPRETATION Once-daily, single-inhaler MF-IND-GLY improved lung function versus ICS-LABA combinations (MF-IND and FLU-SAL) in patients with inadequately controlled asthma. The safety profile was similar across treatment groups. MF-IND-GLY therefore constitutes a good treatment option in these patients. FUNDING Novartis Pharmaceuticals.

Abstract
Aims: This study aimed to identify risk factors related to guidewire insertion (GWI) failure and construct a novel predictive nomogram. In addition, sphincterotome-assisted guidewire insertion (SAGWI) in difficult cases was evaluated for efficacy and safety. Methods: We reviewed the data of 509 patients with malignant colorectal obstruction who underwent endoscopic self-expandable metal stent (SEMS) insertion from 2007 to 2018 in our center, retrospectively. We identify risk factors associated with GWI failure by multivariate logistic regression analysis and construct a novel predictive nomogram. Improvements in the GWI and technical and clinical success rates were assessed for the SAGWI technique. Results: A total of 509 patients with malignant colorectal obstruction were included. Increases of 6.9% and 7.0% were found in the GWI success rate by intention-to-treat (ITT; p < 0.001) and per-protocol (PP; p < 0.001) analyses after SAGWI, respectively. Increases of 6.5% and 6.6% in the technical success rate were found by ITT (p < 0.001) and PP (p < 0.001) analyses after SAGWI, respectively. Increases of 5.8% and 6.0% in the clinical success rate were found by ITT (p < 0.001) and PP (p < 0.001) analyses after SAGWI, respectively. Regarding the GWI failure-related factors, a sharply angulated stricture was an independent risk factor, and an experienced colonoscopist was an independent protective factor. A novel effective predictive nomogram was constructed. Conclusion: The novel predictive nomogram can be conveniently used to identify difficult cases. A sharply angulated stricture and an experienced colonoscopist are independent factors related to GWI failure. The SAGWI technique is an effective and safe method for addressing technically difficult cases.

Abstract
OBJECTIVES To investigate whether second-look endoscopy (SLE)-guided therapy could be used to prevent post-endoscopic variceal ligation (EVL) early bleeding. METHODS Consecutive cirrhotic patients with large esophageal varices (EV) receiving successful EVL for acute variceal bleeding (AVB) or secondary prophylaxis were enrolled. The patients were randomized into a SLE group and a non-SLE group (NSLE) 10 days after EVL. Additional endoscopic interventions as well as proton pump inhibitors and octreotide administration were applied based on the SLE findings. The post-EVL early rebleeding and mortality rates were compared between the two groups. RESULTS A total of 252 patients were included in the final analysis. Post-EVL early rebleeding (13.5% vs 4.8%, P = 0.016) and bleeding-caused mortality (4.8% vs 0%, P = 0.013) were more frequently observed in the NSLE group than in the SLE group. However, post-EVL early rebleeding and mortality rates were reduced by SLE in patients receiving EVL for AVB only but not in those receiving secondary prophylaxis. Patients with Child-Pugh classification B to C at randomization (hazard ratio [HR] 8.77, P = 0.034), AVB at index EVL (HR 3.62, P = 0.003), discontinuation of non-selective β-blocker after randomization (HR 4.68, P = 0.001) and non-SLE (HR 2.63, P = 0.046) were more likely to have post-EVL early rebleeding. No serious adverse events occurred during SLE. CONCLUSION SLE-guided therapy reduces post-EVL early rebleeding and mortality rates in cirrhotic patients with large EV receiving EVL for AVB.

Abstract
It remains challenging for endoscopists to manage pancreaticobiliary diseases in patients with ectopic papilla of Vater by endoscopic retrograde cholangiopancreatography (ERCP). The present study sought to evaluate the efficacy and safety of ERCP for this issue.Consecutive patients with ectopic papilla of Vater who underwent initial ERCP due to pancreaticobiliary diseases were retrospectively analyzed.One hundred seven patients with ectopic papilla of Vater were included. The success rate of cannulation was 83.2%. Endoscopic sphincterotomy, endoscopic papillary balloon dilation, and mechanical lithotripsy were performed in 12 (11.2%), 25 (23.4%), and 1 (0.9%) patients, respectively. The technical success rate was 83.2%; of these, endoscopic nasobiliary drainage, endoscopic retrograde biliary drainage, endoscopic retrograde pancreatic drainage, and stone extraction was conducted in 61 (57.0%), 17 (15.9%), 5 (4.7%), and 45 (42.1%) patients, respectively. Bile duct stone size ≥1 cm, number ≥2, and duodenum stenosis were risk factors for stone extraction inability. Adverse events occurred in 20 (18.7%) patients, including post-ERCP pancreatitis (3.7%), hyperamylasemia (12.1%), and infection of biliary tract (2.8%); all of the adverse events were mild and alleviated by conventional therapies.ERCP is an appropriate choice for pancreaticobiliary diseases in patients with ectopic papilla of Vater due to its high efficacy and safety. Bile duct stone size ≥1 cm, number ≥2, and duodenum stenosis increase difficulties for stone extraction.
