RESUMO
BACKGROUND & AIMS: Endoscopic ultrasound-guided choledochoduodenostomy with a lumen-apposing metal stent (EUS-CDS) is a promising modality for management of malignant distal biliary obstruction (MDBO) with potential for better stent patency. We compared its outcomes with endoscopic retrograde cholangiopancreatography with metal stenting (ERCP-M). METHODS: In this multicenter randomized controlled trial, we recruited patients with MDBO secondary to borderline resectable, locally advanced, or unresectable peri-ampullary cancers across 10 Canadian institutions and 1 French institution. This was a superiority trial with a noninferiority assessment of technical success. Patients were randomized to EUS-CDS or ERCP-M. The primary end point was the rate of stent dysfunction at 1 year, considering competing risks of death, clinical failure, and surgical resection. Analyses were performed according to intention-to-treat principles. RESULTS: From February 2019 to February 2022, 144 patients were recruited; 73 were randomized to EUS-CDS and 71 were randomized to ERCP-M. The mean (SD) procedure time was 14.0 (11.4) minutes for EUS-CDS and 23.1 (15.6) minutes for ERCP-M (P < .01); 40% of the former was performed without fluoroscopy. Technical success was achieved in 90.4% (95% CI, 81.5% to 95.3%) of EUS-CDS and 83.1% (95% CI, 72.7% to 90.1%) of ERCP-M with a risk difference of 7.3% (95% CI, -4.0% to 18.8%) indicating noninferiority. Stent dysfunction occurred in 9.6% vs 9.9% of EUS-CDS and ERCP-M cases, respectively (P = .96). No differences in adverse events, pancreaticoduodenectomy and oncologic outcomes, or quality of life were noted. CONCLUSIONS: Although not superior in stent function, EUS-CDS is an efficient and safe alternative to ERCP-M in patients with MDBO. These findings provide evidence for greater adoption of EUS-CDS in clinical practice as a complementary and exchangeable first-line modality to ERCP in patients with MDBO.

RESUMO
BACKGROUND AIMS: Clinically significant post-endoscopic retrograde cholangiopancreatography (ERCP) bleeding (CSPEB) is common. Contemporary estimates of risk are lacking. We aimed to identify risk factors for and outcomes following CSPEB. METHODS: We analyzed multi-center prospective ERCP data between 2018-2023 with 30-day follow-up. The primary outcome was CSPEB, defined as hematemesis, melena, or hematochezia resulting in: hemoglobin drop ≥20 g/L or transfusion and/or endoscopy to evaluate suspected bleeding, and/or unplanned healthcare visitation and/or prolongation of existing admission. Firth logistic regression was employed. P-values <0.05 were significant, with odds ratios (ORs) and 95% confidence intervals reported. RESULTS: CSPEB occurred following 129 (1.5%) of 8,517 ERCPs (mean onset 3.2 days), with 110 of 4,849 events (2.3%) occurring following higher-risk interventions (sphincterotomy, sphincteroplasty, pre-cut sphincterotomy, and/or needle-knife access). CSPEB patients required endoscopy and transfusion in 86.0% and 53.5% of cases, respectively, with three cases (2.3%) being fatal. P2Y12 inhibitors were held for a median of 4 days (IQR 4) prior to higher-risk ERCP. Following higher-risk interventions, P2Y12 inhibitors (OR 3.33, 1.26-7.74), warfarin (OR 8.54, 3.32-19.81), dabigatran (OR 13.40, 2.06-59.96), rivaroxaban (OR 7.42, 3.43-15.24) and apixaban (OR 4.16, 1.99-8.20) were associated with CSPEB. Significant intraprocedural bleeding post sphincterotomy (OR 2.32, 1.06-4.60), but not post sphincteroplasty, was also associated. Concomitant cardiorespiratory events occurred more frequently within 30 days following CSPEB (OR 12.71, 4.75-32.54). CONCLUSIONS: Risks of antiplatelet-related CSPEB may be underestimated by endoscopists based on observations of suboptimal holding before higher-risk ERCP. Appropriate periprocedural antithrombotic management is essential and could represent novel quality initiative targets.
RESUMO
BACKGROUND AND AIMS: The incidence, risk factors, and outcomes of post-ERCP cholecystitis are poorly described. We aimed to describe cases of post-ERCP cholecystitis from a prospective multicenter registry with protocolized 30-day follow-up. METHODS: Patient- and procedure-related data from 7 centers were obtained. The primary outcome was post-ERCP cholecystitis, defined according to a Delphi-based criteria and causal attribution system. Risk factors and outcomes were described for all cases. RESULTS: Seventeen cases of post-ERCP cholecystitis were identified among 4428 patients with gallbladders undergoing ERCP between 2018 and 2023 (incidence, 0.38%; 95% confidence interval, 0.20-0.57). In ERCPs with covered metal stenting, 7 of 467 resulted in cholecystitis (incidence, 1.50%; 95% confidence interval, 0.40-2.60). Patients had symptoms at a median of 5 days (interquartile range, 5) after ERCP. Management strategies included cholecystectomy, percutaneous cholecystostomy, and endoscopic stent removal/exchange. CONCLUSIONS: Estimates of post-ERCP cholecystitis incidence can inform discussions around procedural risk.

BACKGROUND AND AIMS: Audit and feedback (A&F) for endoscopic retrograde cholangiopancreatography (ERCP) is relatively understudied despite the demonstrated effectiveness of A&F for endoscopic procedures such as colonoscopy. Endoscopist 'report cards' are one A&F tool. We aimed to develop an ERCP report card and assess its appropriateness, acceptability and feasibility through usability testing. METHODS: A prototype report card was designed using a combination of published quality indicators and established predictors of adverse events (AE). Exploratory analyses from a prospective multi-center registry were performed to further identify novel and/or understudied parameters for possible inclusion. Semi-structured interviews with ERCP endoscopists were conducted and framework analysis performed. Validated post-interview usability instruments were administered. Feedback was incorporated to create a final report card. RESULTS: The report card included domains of technical parameters, AE rates/prevention, and patient-reported experience measures (PREMs). Qualitative feedback was positive, with respondents agreeing with inclusion of relevant content in most domains. Post-interview instruments revealed adequate appropriateness and acceptability. PREMs were felt by respondents to be poorly actionable and were replaced with appropriateness of indication and fluoroscopy usage parameters in the final report card. Concerns were raised regarding the feasibility of implementation due to reliance on difficult-to-obtain granular intraprocedural data. CONCLUSIONS: We designed and tested an ERCP report card that has potential to be an effective A&F intervention for endoscopists in clinical practice. Though feasibility of data capture and implementation are currently limitations, advances in video recording and artificial intelligence technologies could accelerate widespread adoption of such a tool.
RESUMO
The 'first night effect' (FNE) is a well-known phenomenon in polysomnographic (PSG) sleep studies, resulting in significant variations in the macrostructure of wakefulness and sleep states, particularly between the initial and subsequent sleep recording sessions. The FNE phenomenon during sleep has been studied in various species, revealing complex variations between several sessions of sleep recording. The present study used a non-invasive PSG method to examine differences between various vigilance states in four adult female dromedary camels during 4 consecutive nights and days of sleep recording. The results indicate the presence of a FNE in the architecture of the dromedary camel's vigilance states. On the first night, the proportions of wakefulness and light non-rapid eye movment (NREM) sleep (drowsiness) were higher, at a mean (standard error of the mean [SEM]) of 40.92% (0.88%) and 14.93% (0.37%), respectively; while the proportion of rumination (mean [SEM] 29.55% [0.92%]) was lower compared to consecutive nights. No FNE was found on deep NREM sleep, while night-time REM sleep had a shorter proportion during the first night compared to subsequent consecutive nights. A significantly lower REM/total sleep time (TST) ratio was observed on the first night. Daytime comparisons did not show any significant differences for the different vigilance states. The increase in wakefulness and light NREM sleep and the reduction in REM sleep and REM/TST sleep on the first night indicate a decline in sleep quality in the dromedary camel due to the FNE. Thus, we recommend excluding from a PSG sleep study at least the first session/night of the recordings to ensure accurate results.
RESUMO
The progressive inflammatory nature of chronic pancreatitis and its sparse therapeutic toolbox remain obstacles in offering patients durable solutions for their symptoms. Obstruction of the main pancreatic duct by either strictures or stones represents a scenario worthy of therapeutic focus, as nearly all patients with pancreatitis eventually have intraductal stones. A more recent option for removal of main duct stones is extracorporeal shock wave lithotripsy (ESWL). In an effort to explore the role of ESWL in a Canadian setting, we evaluated our initial experience over an 8-year period (2011-2019).

BACKGROUND: Pancreatic fluid collections (PFCs), including walled-off necrosis (WON), are commonly described sequelae of pancreatitis. Endosonography-guided PFC drainage can be performed using plastic stents (PS), fully covered self-expanding metal stents (FCSEMS), or lumen-apposing metal stents (LAMS). We performed a retrospective study comparing clinical outcomes and adverse events by stent type. METHODS: In this historical cohort, patients undergoing endosonography-guided PFC drainage from 2010 to 2019 were divided into groups: those treated with (1) PS, (2) FCSEMS, and (3) LAMS. Clinical success, the primary outcome, was defined as complete resolution or size reduction of ≥ 50%, with resolution of symptoms and no reintervention required at 3 months following the index procedure. Adverse events (AEs) and procedure times were also evaluated. RESULTS: Fifty-eight patients were included. Procedure times were significantly shorter with LAMS (21.4 ± 10.8 min versus 53.0 ± 24.4 min for FCSEMS and 65.9 ± 23.4 min for PS, p < 0.001). Clinical success rates for WON were higher with LAMS compared with FCSEMS (95.7% vs 66.7%, respectively; p = 0.04). For all PFCs, treatment with LAMS trended towards higher clinical success rates compared with PS and FCSEMS (96.3% vs 81.8% vs 77.8%, respectively; p = 0.14). Early AEs (within 1 week) occurred at significantly lower rates in the LAMS group compared to PS and FCSEMS (0% vs 33.3% vs 10.6%, respectively; p = 0.006), as did late AEs (7.4% vs 44.5% vs 40%, respectively; p = 0.01). CONCLUSIONS: LAMS is superior in terms of WON clinical success, favorable in terms of lower adverse event profile, and shorter in terms of procedural time compared to FCSEMS and PS. LAMS can be considered as an initial approach for WON, given that clinical success in WON is lower when using PS or FCSEMS, though more high-quality data are needed.

BACKGROUND: The morphology of the major papilla affects the difficulty of endoscopic retrograde cholangiopancreatography (ERCP), but no associations with adverse events have previously been established. We aimed to assess whether papillary morphology predicts ERCP adverse events. METHODS: A retrospective analysis was performed of a prospective registry of patients undergoing ERCP for biliary indications. The primary outcome was post-ERCP pancreatitis (PEP), with secondary outcomes including other adverse events and procedural outcomes such as inadvertent pancreatic duct cannulation, cannulation time, and attempts. Papillae were classified as normal (Type I), small or flat (Type II), bulging (Type IIIa), pendulous (Type IIIb), creased (Type IV), or peri-diverticular (Type D). Outcomes were ascertained prospectively at 30 days from index procedures. RESULTS: A total of 637 patients with native papillae were included. Compared to Type I papillae, Type II and Type IIIb papillae were associated with PEP, with adjusted odds ratios (AOR) of 7.28 (95% confidence intervals, CI, 1.84-28.74) and 4.25 (95% CI 1.26-14.32), respectively. Type II and IIIb papillae were associated with significantly longer cannulation times by 5.37 (95% CI 2.39-8.35) and 4.01 (95% CI 1.72-6.30) minutes, respectively. Type IIIb papillae were associated with lower deep cannulation success (AOR 0.17, 95% CI 0.06-0.48). CONCLUSION: Papillary morphology is an important factor influencing both ERCP success and outcomes. Understanding this is key for managing intraprocedural approaches and minimizing adverse events. PROSPECTIVE REGISTRY REGISTRATION: Clinicaltrials.gov identifier NCT04259580.

Invariant natural killer T (iNKT) cells are being considered as potential targets for immunotherapeutic strategies in a variety of conditions including sickle cell disease (SCD). However, relatively little is known about the fate of iNKT cell subsets in children with SCD. Herein, quantitative and qualitative analyses of circulating iNKT cell subsets were carried out in 120 children in steady state and 30 healthy controls. Children with SCD displayed significantly elevated levels of circulating iNKT cell subsets with a preferential polarization toward Th2-like cells. The known SCD modifiers did not influence levels of iNKT cell subsets, except that children carrying the Bantu haplotype exhibited elevated levels of CD4iNKT cells, and to a lesser degree CD8iNKT cells. Collectively, these findings indicate that circulating iNKT cell subsets are significantly increased in children with SCD, and highlight the existence of imbalanced production of cytokines toward Th2-like phenotype, which seems to be associated with genetic polymorphisms.

BACKGROUND: Endoscopic retrograde cholangio-pancreatography (ERCP) is commonly performed in the management of pancreatic and biliary disease. Duodenoscopes are specialized endoscopes used to perform ERCP, and inherent to their design, a high rate of persistent bacterial contamination exists even after automated reprocessing and disinfection. Consequently, in recent years, ERCP has been associated with infection transmission, leading to several fatal patient outbreaks. Due to increasing fears over widespread future duodenoscope-related outbreaks, regulatory bodies have called for alterations in the design of duodenoscopes. A duodenoscope has recently been developed that employs a disposable cap. This novel design theoretically eliminates the mechanism behind persistent bacterial contamination and infection transmission. However, there are no data demonstrating persistent bacterial contamination rates, technical success rates, or clinical outcomes associated with these duodenoscopes. METHODS: A parallel arm randomized controlled trial will be performed for which 520 patients will be recruited. The study population will consist of consecutive patients undergoing ERCP procedures for any indication at a high-volume tertiary care centre in Calgary, Alberta, Canada. Patients will be randomized to an intervention group, that will undergo ERCP with a novel duodenoscope with disposable cap, or to a control group who will undergo ERCP with a traditional duodenoscope. Co-primary outcomes will include persistent bacterial contamination rates (post automated reprocessing) and ERCP technical success rates. Secondary outcomes include clinical success rates, overall and specific early and late adverse event rates, 30-day mortality and healthcare utilization rates, procedure and reprocessing times, and ease of device use. DISCUSSION: The ICECAP trial will answer important questions regarding the use of a novel duodenoscope with disposable cap. Specifically, persistent bacterial contamination, technical performance, and relevant clinical outcomes will be assessed. Given the mortality and morbidity burden associated with ERCP-related infectious outbreaks, the results of this study have the capacity to be impactful at an international level. TRIAL REGISTRATION: This trial was registered on clinicaltrials.gov (NCT04040504) on July 31, 2019.

Silicon nanoribbons - one dimensional silicon structures with a pentagonal atomic structure and mixed sp2- and sp3-hybridisation - grow on Ag(110) upon deposition of silicon. These nanostructures are viewed as promising candidates for modern day electronics as they are comprised of the same element as today's semiconductor devices. Even though they have been studied extensively over the last decade, only little is known about their unoccupied band structure which is important for possible future optoelectronics, semiconductor, and spintronics applications. In order to elucidate the unoccupied band structure of the nanoribbons, k-resolved inverse photoemission spectroscopy (KRIPES) studies were performed on both nanoribbon structures reported in the literature as well as on the bare Ag(110) substrate within the energy range of E-EF = 0-6.5 eV. The obtained experimental results are compared to density functional theory (DFT) calculated band structures to assign individual spectral features to specific bands. Since even small changes in the structural model of the nanoribbons lead to a change in the calculated band structure, this comparison allows us to assess the validity of the proposed structural models.
RESUMO
PURPOSE: As treatment options for children with sickle cell anemia (SCA) continue to expand survival, evaluation of factors associated with health-related quality of life (HRQoL) is becoming an important aspect for further improving clinical management. Although the general features of SCA are similar, factors influencing HRQoL within a country may differ from those of other countries, therefore this study aimed to explore factors affecting HRQoL in children with SCA living in the Sultanate of Oman. METHODS: This was a cross-sectional study in which the PedsQL™ Sickle Cell Disease Module was used to evaluate the overall HRQoL in children with SCA. The socio-demographic data, clinical, and treatment outcomes were collected. Univariate and multivariate linear regression analyses were used to identify predictors of HRQoL. RESULTS: A total of 123 children with SCA, aged from 2 to 16 years were enrolled. The mean total HRQoL score was 52 ± 15% (9-94), where Worry II scale recorded the highest score. The multiple regression analysis revealed that the only predictors of total HRQoL score were hemoglobin F (B = 0.64, 95% confidence interval [CI] 0.149-1.118, P = 0.009) and to a lesser degree white blood cell count (B = - 0.99, 95% CI - 1.761 to - 0.198, P = 0.01), independently of other study parameters such as age, gender, spleen status, and hydroxyurea therapy. CONCLUSIONS: Collectively, these findings indicated that hemoglobin F out-weighted white blood cell count in predicting HRQoL in Omani children with SCA. Recognition of these factors could help health professionals to develop effective strategies to improve the overall HRQoL in these young patients.

Summary: Delays in the diagnosis and treatment of colon adenocarcinoma are distressing to patients and clinicians alike. Of 224 patients with resected colon cancer identified via a province-wide administrative database, 170 (76%) received their colonoscopy from a gastroenterologist (GI). Patients waited significantly longer between their colonoscopy and surgical resection when the colonoscopy was performed by a GI within an urban city (43 v. 27 d; p = 0.02). The total time from family practice referral to colonoscopy to surgical resection was shorter when a surgeon performed colonoscopy within an urban setting (105 v. 114 d; p = 0.03). In community settings, there were no significant differences in any interval, regardless of which service performed the colonoscopy.

BACKGROUND: The liver is the most commonly damaged organ in abdominal trauma. The management of liver trauma has experienced many changes over the last two decades. Currently there is a trend toward a non-operative treatment warranted by the successful pediatric experience and better results recorded in many trauma centers worldwide. This study aimed to evaluate outcomes of operative and non-operative management of liver trauma in our institution over the last five years. METHODS: The patients with a diagnosis of blunt or penetrating liver injuries, admitted and managed in our hospital from January 2012 to December 2016 were retrospectively studied. The patients were divided into 2 groups, operated and non-operated groups, according to the initial management considered appropriate at the time of patient admission. Clinical features and outcomes were analyzed. RESULTS: The study involved 83 patients, with a mean age of 33 years and a marked male predominance (85.5%). The most common type of lesions was blunt trauma and the main cause was road traffic accidents. Sixty-eight liver injuries (81.9%) were of low severity (grades I, II, III), while 15 (18.1%) were of high severity (grade IV or greater). Fifty-six patients (67.5%) had multiple injuries. Surgical treatment was performed in 26 (31.3%) patients. Non-operative management was undertaken in 57 cases (68.7%). The morbidity and mortality rates were clearly lower in non-operative patients compared to those in the operated group. CONCLUSIONS: Careful non-operative management is an adequate therapeutic strategy for the patients suffering from liver trauma with stable hemodynamics. Patients with complex hepatic trauma and especially those with other organ injuries continue to have significantly higher mortality.

BACKGROUND AND AIMS: EUS is a potentially useful modality to assess severity of inflammation in ulcerative colitis (UC). We assessed the reliability of existing EUS indices and correlated them with endoscopic and histologic scores. METHODS: Four blinded endosonographers assessed 58 endoscopic and EUS videos in triplicate, from patients with UC. Intrarater and interrater reliability of the hyperemia and Tsuga scores were estimated by using intra-class correlation coefficients (ICCs). Correlation with the Mayo endoscopy score, modified Baron score (MBS), Ulcerative Colitis Endoscopic Index of Severity (UCEIS), and Geboes histopathology score (GHS) were calculated by using bootstrapping methods. A RAND consensus process led to development of standardized definitions and a revised EUS-UC score. RESULTS: ICCs for intrarater reliability were 0.76 (95% confidence interval [CI], 0.71-0.80) for the hyperemia score and 0.85 (95% CI, 0.79-0.89) for the Tsuga score. Corresponding values for interrater reliability were 0.34 (95% CI, 0.25-0.42) and 0.36 (95% CI, 0.24-0.46). Correlation between hyperemia and Tsuga scores to Mayo scoring system, MBS, UCEIS, and the GHS were 0.39 (95% CI, 0.15-0.61) and 0.28 (95% CI, 0.04-0.51), 0.38 (95% CI, 0.16-0.57) and 0.25 (95% CI, -0.01-0.48), 0.41 (95% CI, 0.16-0.62) and 0.27 (95% CI, 0.01-0.50), 0.37 (95% CI, -0.01-0.48) and 0.24 (95% CI, 0.13-0.57), respectively. The revised EUS-UC score included bowel wall thickening, depth of inflammation, and hyperemia. CONCLUSIONS: Although substantial to almost perfect intrarater agreement existed for EUS indices in UC, interrater agreement was fair. Standardization of item definitions with development of a revised evaluative instrument has potential application as an evaluative and prognostic tool for UC.

BACKGROUND AND AIMS: In patients who have undergone ERCP with biliary stenting for postsurgical bile leaks, the optimal method (ERCP or gastroscopy) and timing of stent removal is controversial. We developed a clinical prediction rule to identify cases in which a repeat ERCP is unnecessary. METHODS: Population-based study of all patients who underwent ERCP for management of surgically induced bile leaks between 2000 and 2012. Multivariate and binary recursive partitioning analyses were performed to generate a rule predicting the absence of biliary pathology on repeat endoscopic evaluation. RESULTS: A total of 259 patients were included. On multivariate analysis, postsurgical normal alkaline phosphatase (ALP; OR, 2.26; 95% CI, 1.03-4.99), time from surgery to first ERCP < 8 days (OR, 2.47; 95% CI, 1.15-5.31), and minor leak with no other pathology on initial ERCP (OR, 6.74; 95% CI, 1.75-25.89) were independently associated with the absence of persistent bile leak and other pathology on repeat ERCP. The derived rule included laparoscopic cholecystectomy, normal postsurgical ALP, minor leak with no other pathology on initial ERCP, and an interval from initial to repeat ERCP between 4 and 8 weeks. When all 4 criteria were met, the rule had a sensitivity of 94% (95% CI, 83%-99%) and a negative predictive value of 93% (95% CI, 81%-99%). Optimism-adjusted sensitivity and negative predictive value were 88% (95% CI, 76%-96%) and 86% (95% CI, 73%-96%), respectively. CONCLUSIONS: This clinical decision rule identifies patients who can have their biliary stents removed via gastroscopy, which may improve patient safety and healthcare utilization.

BACKGROUND: As endoscopic ultrasound-guided tissue acquisition techniques evolve, there is increasing interest in obtaining optimal histological samples to improve diagnostic accuracy. In this study, we aimed to assess the tissue acquisition success rate and test performance characteristics of a novel endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) system. METHODS: We performed a retrospective review of consecutive patients undergoing EUS-guided tissue sampling of solid lesions using the SharkCore fine needle system in a tertiary referral facility. At least two passes were submitted for histology and diagnostic accuracy was evaluated. Comparison standard was based on final surgical pathology or minimum six-month clinical follow-up. RESULTS: Seventy-nine patients underwent 85 EUS-FNB procedures. Of the 85 histology specimens, 78 (91.7%) were adequate for diagnostic examination (includes six atypical/suspicious for adenocarcinoma). The sensitivity, specificity, and accuracy for diagnosis of malignancy with FNB were 87.1, 100, and 90.6%, respectively. Cytology was simultaneously sent in 43 cases with the same needle in addition to histology. Out of the 14 cases that were atypical/suspicious for adenocarcinoma or non-diagnostic on cytology, 11 cases (78.6%) achieved definite diagnoses on histology. The overall sensitivity, specificity, and accuracy for diagnosis of malignancy combining histology and cytology were 90.3, 100, and 92.9%, respectively. No complications were reported after the procedures. CONCLUSION: In this initial experience with a new EUS-guided FNB system, obtaining small cores to submit for histological analysis was safe, technically feasible, and highly accurate. Most of the histological cores obtained via FNB yielded a definite diagnosis including in cases with equivocal cytomorphology. Further study is required to confirm these findings.

Atrial fibrillation and hypertension are often coexistent. Their incidence increases with advancing age and they are responsible for considerable morbidity and mortality. The relation between theses 2 diseases has long been discussed and determined by clinical studies. Left ventricular hypertrophy and left atrial remodeling during hypertension favor the development of atrial fibrillation. AF during hypertension increases the risk of thromboembolic complications and heart failure. In patients with hypertension, pharmacological treatment may control the cardiac structural changes and retard or prevent the occurrence of atrial fibrillation. In case of atrial fibrillation, treatment should be focused on the control of heart rate and rhythm and the prevention of thromboembolic accidents. A strict control of blood pressure is highly required in this situation.
