Determinants and outcomes of acute pancreatitis in patients hospitalized for COVID-19: Early pandemic experience.

OBJECTIVES: To examine the predictors and outcomes associated with the development of acute pancreatitis (AP) in patients hospitalized with Coronavirus Disease 2019 (COVID-19). METHODS: This is an observational analysis of the 2020 National Inpatient Sample Database. The study includes adult patients who were admitted with a confirmed diagnosis of COVID-19 and stratifies them based on the presence or absence of AP during their hospitalization. Predictors of AP development between the two groups and differences in outcomes are examined. Multivariate logistic regression analysis using Stata/BE 17.0 is conducted, with adjustments made for age, sex, race, and Charlson Comorbidity Index (CCI). Statistical significance is determined at a p-value of <0.05. RESULTS: Significant factors associated with an increased risk of AP in COVID-19 patients include Hispanic ethnicity, higher Charlson Comorbidity Index (CCI) score, residence in states located in the southern region, history of chronic kidney disease, chronic liver disease, malnutrition, portal hypertension, and alcohol use. COVID-19 patients who developed AP were also found to be at higher risk of adverse outcomes, including mortality, acute coronary syndrome, acute kidney injury, sepsis, septic shock, in-hospital cardiac arrest, invasive mechanical ventilation, upper gastrointestinal bleeding, prolonged length of stay, and increased healthcare cost. CONCLUSIONS: In hospitalized patients with COVID-19, the presence of AP is associated with increased mortality and morbidity. Risk factors for developing AP in this population include Hispanic ethnicity, residence in the southern region, higher Charlson Comorbidity Index (CCI) score, history of chronic kidney disease, chronic liver disease, malnutrition, portal hypertension, and alcohol use.

Clinical outcomes and learning curve for ERCP during advanced endoscopy training: a comparison of supine versus prone positioning.

BACKGROUND AND AIMS: No studies have evaluated trainees' outcomes when learning ERCP with patients in the supine and prone positions simultaneously. We aimed to assess whether patient position impacts procedural outcomes and learning curve. METHODS: We prospectively evaluated patients undergoing ERCP by a supervised advanced endoscopy trainee (AET) at a tertiary care center. Adult patients with native papillae were included. The AET was universally given 5 attempts per cannulation. Outcomes were evaluated quarterly. RESULTS: Successful cannulation was achieved in 44 supine (69%) and 17 prone (68%) patients (P = .95). Although mean time to reach the papilla was shorter in the supine patient position, time to biliary cannulation (7.8 vs 9.4 minutes, P = .53) and number of attempts were similar. A stepwise increase was seen in cannulation rates throughout the academic year (P < .01) and increased more in supine patients (P = .01). Procedure and total room times were shorter in supine patients. CONCLUSIONS: Shorter procedure and room turnover times and a comparable cannulation rate were found for supine versus prone ERCP.

Gastroenterologist's Guide to Gastrostomies.

Gastroenterologists are frequently consulted for evaluation feeding tube placement, or for management of complications in an existing feeding tube. Though a frequent topic of consultation for GI Fellows, there are few comprehensive resources for feeding tube placement and troubleshooting available. In this review, we discuss different types of feeding tubes, when each should be considered, and various methods and techniques for placement. Considerations for when one type, method, technique, or specialty may be preferred over the other will be discussed. Additionally, we discuss management of the many complications of indwelling feeding tubes. Our goal is to create a comprehensive review for gastroenterologists to cover clinically relevant questions related to feeding tube placement and management.

"Wet Heparin" and "Wet Saline" EUS-Guided Liver Biopsy Techniques Both Provide High Rates of Specimen Adequacy for Benign Parenchymal Liver Disease.

BACKGROUND: Endoscopic ultrasound-guided liver biopsy (EUS-LB) has emerged as a viable mean to obtain core tissue, but the optimal tools and techniques are still an area of active investigation. AIMS: (1) To compare tissue adequacy using "wet saline" (WS) vs. "wet heparin" (WH) technique (2) To compare post-procedure pain between EUS-LB and percutaneous liver biopsy (PLB). METHODS: Retrospective review of consecutive patients who underwent EUS-LB and PLB for benign parenchymal liver disease between May 2017 to October 2019 at a single tertiary veterans affairs medical center. RESULTS: About 257 biopsies from 217 patients were included. Among the 102 EUS-LB specimens, 53 were obtained using WS technique and 49 were obtained using WH technique. Specimen adequacy was similar in both groups. Median Aggregate Specimen Length (ASL) and length of longest piece did not differ significantly between WS and WH groups. Clots were present more frequently in the WS group. Among patients who underwent EUS-LB of both right and left liver lobes, an adequate biopsy was obtained in 85% of patients in the WS group and 96% of patients in the WH group. The percentage of patients experiencing immediate post-procedure pain was higher with PLB compared to EUS-LB, but these results were not statistically significant. CONCLUSIONS: Both WS and WH EUS-LB techniques can offer high rates of specimen adequacy with low rates of pain and other post-procedure complications.

Gastric intestinal metaplasia: when to treat? How to treat?

PURPOSE OF REVIEW: Gastric intestinal metaplasia (GIM) is an attractive target for surveillance and treatment as it can progress to gastric adenocarcinoma (GAC). Yet, GIM remains a challenging area for clinicians as most patients do not progress to cancer, and there are conflicting data regarding the benefits of surveillance and therapy. This review aims to summarize recently published GIM surveillance guidelines, to discuss, which patients with GIM may benefit from treatment, and to review pivotal and recent literature on GIM therapy. RECENT FINDINGS: Guidelines published by American, British, and European gastroenterology societies do not recommend universal surveillance, but do suggest endoscopic surveillance in patients with risk factors for progression to GAC. Although light examination for at least 7 min and mapping biopsies may increase yield for dysplasia and GAC. In randomized trials, Helicobacter pylori eradication reduced risk of dysplasia and cancer. In GIM with visible dysplasia and early-stage GAC, endoscopic resection improves quality of life without reducing survival compared with surgery. Endoscopic ablation therapies have shown promise for invisible or extensive dysplasia. SUMMARY: Endoscopic resection is appropriate for visible dysplasia and early-stage GAC without high-risk features that persists despite H. pylori eradication therapy. Prospective studies are needed to assess the utility of endoscopic ablation in GIM.

Training of hepatology providers improves the screening and resultant interventions for alcohol use disorder.

Alcohol use disorder (AUD) screening is important but focused training with using AUDIT-10 with counselling/mental health (MH) referral may be needed. We aimed to compare the effect of training on AUD screening/intervention in hepatology clinics in pre vs post-training phases of a quality-improvement initiative. Pre-training encounters were evaluated for inquiry into AUD, AUDIT-10 and MH referrals. Dedicated AUD-related training was provided to hepatology providers and analyses repeated post-training. Pre-training (n = 378) and post-training patients(n = 318) had similar demographics and disease characteristics. Post-training there was higher inquiry about alcohol(92% vs 80%, P < .0001), counselling (82% vs 68%, P < .0001). This led to higher diagnosis of drinkers (49% vs 31%, P < .0001) of whom higher proportion had AUDIT-10 administered(91% vs 34%, P < .0001) and referred to MH(29% vs 8%, P < .0001). On regression presumed alcohol-related aetiology, younger age and post-training period were associated with AUDIT-10 administration. AUD-focused training significantly improves rates of screening and MH referral for problem drinking in a hepatology clinic population.

Tendonitis and Tendon Rupture After Treatment With Rituximab: A Case Series.

CLINICAL DATA: Rituximab is a mouse/human chimeric anti-CD20 IgG1 monoclonal antibody used to treat cancer and autoimmune conditions. Side effects of rituximab include fever, rash, cytopenia and hypotension, back pain, arthralgia, and myalgia. Here, we report on 3 patients who developed moderate to severe tendonitis after the second infusion of rituximab. THERAPEUTIC CHALLENGE: We report 3 patients who developed tendonitis after the second infusion of rituximab. These patients were undergoing treatment for connective tissue diseases. All 3 patients received 2 rituximab infusions, 2 weeks apart. The 3 cases developed clinical tendonitis that was confirmed by magnetic resonance imaging in 2 cases. INTERPRETATION: This is the first case series reporting new onset tendonitis in patients with connective tissue diseases after rituximab therapy. All 3 cases developed tendonitis 1 week after receiving the second dose of rituximab. Clinical features of tendonitis resolved 3-4 months in all cases. The underlying pathogenic mechanism by which rituximab causes tendonitis is not clear, but tendonitis and tendon rupture have been reported after using other medications such as quinolones. The tendon damage was progressive leading to tendon rupture in 1 patient, highlighting the importance of early recognition. It is plausible that there is a cause-effect relation between tendonitis and administration of rituximab in our 3 cases, since none of these cases had previous history of tendonitis; however, more data are needed to confirm this observation.

The National Burden of Colorectal Cancer in the United States from 1990 to 2019.

CRC accounts for approximately a tenth of all cancer cases and deaths in the US. Due to large differences in demographics among the different states, we aim to determine trends in the CRC epidemiology and across different states, age groups, and genders. CRC rates, age-adjusted to the standard US population, were obtained from the GBD 2019 database. Time trends were estimated as annual percentage change (APC). A pairwise comparison was conducted between age- and gender-specific trends using the tests of parallelism and coincidence. Age-specific trends were also assessed in two age subgroups: younger adults aged 15-49 years and older adults aged 50-74 years. We also analyzed the prevalence, incidence, mortality, and DALYs in the US between 1990 and 2019. A total of 5.53 million patients were diagnosed with CRC in the US between 1990 and 2019. Overall, CRC incidence rates have significantly increased in younger adults (11.1 per 100,000 persons) and decreased in older adults (136.8 per 100,000 persons) (AAPC = 1.2 vs. -0.6; AAPC difference = 1.8, p < 0.001). Age-specific trends were neither identical (p < 0.001) nor parallel (p < 0.001), suggesting that CRC incidence rates are different and increasing at a greater rate in younger adults compared to older adults. However, for both men and women (49.4 and 35.2 per 100,000 persons), incidence rates have decreased over the past three decades at the same rate (AAPC = -0.5 vs. -0.5; AAPC difference = 0, p = 0.1). Geographically, the southern states had the highest mortality rates with Mississippi having the highest rate of 20.1 cases per 100,000 population in 2019. Massachusetts, New York, and the District of Colombia had the greatest decreases in mortality over the study period (-42.1%, -41.4%, and -40.9%). Decreased mortality was found in all states except Mississippi, where the mortality of CRC increased over the study period (+1.5%). This research provides crucial insights for policymakers to tailor resource allocation, emphasizing the dynamic nature of CRC burden across states and age groups, ultimately informing targeted strategies for prevention and intervention.

Lumen-Apposing Metal Stent With and Without Concurrent Double-Pigtail Plastic Stent for Pancreatic Fluid Collections: A Comparative Systematic Review and Meta-Analysis.

Background: Lumen-apposing metal stents (LAMSs) are often used to drain pancreatic fluid collections (PFCs). However, adverse events, such as stent obstruction, infection, or bleeding, have been reported. Concurrent double-pigtail plastic stent (DPPS) deployment has been suggested to prevent these adverse events. This meta-analysis aimed to compare the clinical outcomes of LAMS with DPPS vs. LAMS alone in the drainage of PFCs. Methods: An extensive search was conducted in the literature to include all the eligible studies that compared LAMS with DPPS vs. LAMS alone for drainage of PFCs. Pooled risk ratios (RRs) with the 95% confidence intervals (CIs) were obtained within a random-effect model. The outcomes were technical and clinical success, and overall adverse events, including stent migration and occlusion, bleeding, infection, and perforation. Results: Five studies involving 281 patients with PFCs (137 received LAMS plus DPPS vs. 144 received LAMS alone) were included. LAMS plus DPPS group was associated with comparable technical success (RR: 1.01, 95% CI: 0.97 - 1.04, P = 0.70) and clinical success (RR: 1.01, 95% CI: 0.88 - 1.17). Lower trends of overall adverse events (RR: 0.64, 95% CI: 0.32 - 1.29), stent occlusion (RR: 0.63, 95% CI: 0.27 - 1.49), infection (RR: 0.50, 95% CI: 0.15 - 1.64), and perforation (RR: 0.42, 95% CI: 0.06 - 2.78) were observed in LAMS with DPPS group compared to LAMS alone but without a statistical significance. Stent migration (RR: 1.29, 95% CI: 0.50 - 3.34) and bleeding (RR: 0.65, 95% CI: 0.25 - 1.72) were similar between the two groups. Conclusions: Deployment of DPPS across LAMS for drainage of PFCs has no significant impact on efficacy or safety outcomes. Randomized, controlled trials are necessary to confirm our study results, especially in walled-off pancreatic necrosis.

Candida Esophagitis Presenting as an Esophageal Pseudotumor.

The typical appearance of Candida esophagitis is white plaque-like membranes within the esophagus. We describe a unique case of Candida esophagitis that presented as a bulky, malignant-appearing, positron emission tomography-computed tomography-avid mass on endoscopy. Esophageal candidiasis persisted despite a standard course of antifungal medications (fluconazole 400 mg daily for 14 days), and eradication was successful only after fluconazole 800 mg daily was administered. Malignancy was excluded based on 2 separate sessions of endoscopy with multiple biopsies and finally with endoscopic full-thickness resection assisted by preresection closure with an over-the-scope clip.

Causes of Failure to Capture in Pacemakers and Implantable Cardioverter-defibrillators.

The number of patients with implantable electronic cardiac devices is continuously increasing. As more pacemakers and implantable cardioverter-defibrillators (ICDs) are being placed, a basic understanding of some troubleshooting for devices is becoming essential. Loss of capture can be an emergent presentation for an unstable patient and can be encountered intermittently in hospitalized patients. There are many causes for a loss of capture, with the timing of the implant having a high correlation with certain causes over others. The most common acute cause just after the insertion procedure is lead dislodgement or malposition. In comparison, an increase in the required threshold promoting a loss of capture can happen after months to years of insertion of the pacemaker or ICD. This change can be due to a cardiomyopathy, fibrosis medications, metabolic imbalance, lead fracture, or an exit block. Loss of capture can also occur from external electrical stimuli and inappropriate pacemaker or ICD settings. Further, there are also potential noncardiac causes, such as medications, electrolyte imbalance, and acidemia. A knowledge of these factors is essential for health care providers, given the morbidity and mortality that can potentially be associated with device-related issues, especially in patients who are dependent on the included pacing function.
