ABSTRACT
BACKGROUND: Adequate response to moderate (conscious) sedation varies significantly between individuals. Polymorphisms in genes encoding drug metabolizing enzymes can lead to inter-individual variability in drug efficacy, potentially influencing sedation requirements during endoscopic procedures. OBJECTIVES: The aim of this study was to assess the potential role of inter-individual variation in inherited polymorphisms of drug-metabolizing enzymes, cytochrome P450 (CYP450), specifically CYP3A4 and CYP3A5, in sedation requirements for outpatient endoscopic procedures. METHODS: A retrospective analysis of sedation requirements and pharmacogenomics data in 106 unique patients who received outpatient esophagogastroduodenoscopy (EGD), colonoscopy, or both between December 2011 and February 2019 was conducted. Patients were divided into two groups based on their sedation requirements during endoscopy (high vs. normal sedation). RESULTS: Patients with reduced a CYP2C19 metabolism (poor + intermediate metabolizers) (odds ratio [OR] = 0.38, 95% confidence interval [CI]: 0.16-0.91, p = 0.03), poor CYP3A5 metabolism (OR = 0.25, 95% CI: 0.095-0.65, p = 0.0046), and poor UGT1A1 (OR = 2.76, 95% CI: 1.07-7.13, p = 0.08) had higher odds of requiring normal sedation compared to those with CYP2C19 increased metabolism, CYP3A5 intermediate metabolism, and UGT1A1 intermediate metabolism. CONCLUSION: Information about inter-individual variation in (CYP450) genes may be useful for determining the sedation requirements for outpatient endoscopic procedures. We found that patients with reduced CYP2C19 metabolism, poor CYP3A5 metabolism, and poor UGT1A1 metabolism were more likely to require normal sedation requirements during outpatient endoscopic procedures.
ABSTRACT
Mpox is a rare infection caused by the zoonotic orthopoxvirus. We present the case of a 44-year-old man with HIV and a history of kidney transplant who presented with mpox and developed proctitis-associated bowel obstruction, urinary retention, and eosinophilia. Our case highlights potential gastrointestinal manifestations of severe mpox infection.
ABSTRACT
BACKGROUND: Post-operative cardiac complications occur infrequently but contribute to mortality after liver transplantation (LT). Artificial intelligence-based algorithms based on electrocardiogram (AI-ECG) are attractive for use during pre-operative evaluation to screen for risk of post-operative cardiac complications, but their use for this purpose is unknown. AIMS: The aim of this study was to evaluate the performance of an AI-ECG algorithm in predicting cardiac factors such as asymptomatic left ventricular systolic dysfunction or potential for developing post-operative atrial fibrillation (AF) in cohorts of patients with end-stage liver disease either undergoing evaluation for transplant or receiving a liver transplant. METHODS: A retrospective study was performed in two consecutive adult cohorts of patients who were either evaluated for LT or underwent LT at a single center between 2017 and 2019. ECG were analyzed using an AI-ECG trained to recognize patterns from a standard 12-lead ECG which could identify the presence of left ventricular systolic dysfunction (LVEF < 50%) or subsequent atrial fibrillation. RESULTS: The performance of AI-ECG in patients undergoing LT evaluation is similar to that in a general population but was lower in the presence of prolonged QTc. AI-ECG analysis on ECG in sinus rhythm had an AUROC of 0.69 for prediction of de novo post-transplant AF. Although post-transplant cardiac dysfunction occurred in only 2.3% of patients in the study cohorts, AI-ECG had an AUROC of 0.69 for prediction of subsequent low left ventricular ejection fraction. CONCLUSIONS: A positive screen for low EF or AF on AI-ECG can alert to risk of post-operative cardiac dysfunction or predict new onset atrial fibrillation after LT. The use of an AI-ECG can be a useful adjunct in persons undergoing transplant evaluation that can be readily implemented in clinical practice.

Luminal strictures can occur as part of many different gastrointestinal (GI) disorders anywhere along the GI tract and affect all age groups. The end goal of managing any stricture is to re-establish an adequate and durable luminal patency that is sufficient to resolve the presenting clinical symptoms. Treatment options can be generally categorized into medical, endoscopic, and surgical. However, within each of these categories, multiple different options are available. Therefore, choosing the best treatment modality is often challenging and depends on multiple factors including the type, location, and complexity of the stricture, as well as the preference of the treating physician. In this article, we will review the most current literature regarding foregut strictures, particularly esophageal and gastric, beyond dilation.

OBJECTIVE: To reduce health care facility-onset (HCFO) Clostridioides difficile infection (CDI) incidence by improving diagnostic stewardship and reducing the inappropriate testing of C difficile assays. PATIENTS AND METHODS: A multidisciplinary team conducted a quality improvement initiative from January 1, 2020, through March 31, 2021. Clostridioides difficile infection and inappropriate testing were identified via electronic health records using predefined criteria related to stool quantity/caliber, confounding medications, and laboratory data. An intervention bundle was designed including (1) provider education, (2) implementation of an appropriate testing algorithm, (3) expert review of C difficile orders, and (4) batch testing of assays to facilitate review and cancellation if inappropriate. RESULTS: Compared with a baseline period from January to September 2020, implementation of our intervention bundle from December 2020 to March 2021 resulted in an 83.6% reduction in inappropriate orders tested and a 41.7% reduction in HCFO CDI incidence. CONCLUSION: A novel prevention bundle improved C difficile diagnostic stewardship and HCFO CDI incidence by reducing testing of inappropriate orders. Such initiatives targeting HCFO CDI may positively affect patient safety and hospital reimbursement.
ABSTRACT
Background and study aims Anticoagulation (AC) and antiplatelet (AP) therapy may increase the risk of gastrointestinal bleeding after double balloon enteroscopy (DBE); however, limited data are currently available regarding the incidence. The aim of this study was to assess the incidence and clinical characteristics of post-DBE bleeding in patients on AC and AP therapy. Patients and methods The medical records of patients who underwent DBE between 2009 and 2013 at Mayo Clinic, Florida, were retrospectively reviewed. Patients were divided into three groups: 1) continued AP therapy; 2) AC therapy; and 3) neither AP nor AC at the time of DBE. Follow-up data were collected at 60 days and 1 year. Results A total of 683 patients were identified; 43 on AC, 183 on AP and 457 not on AP or AC therapy. The most common indication for DBE was obscure gastrointestinal bleeding in the groups on and not on AP (85.3â% vs 70.9â%, P â<â0.0001). There was no statistical difference in post-DBE bleeding rates in patients on AP vs not on AP at 60 days (11.5â% vs 7.5â%, P â=â0.12) or 1 year (19.9â% vs 15.7â%, P â=â0.23). Rates of bleeding in patients on AC were 11.6â% within 60 days and 22.5â% within 1 year. Multivariate analysis reflected American Society of Anesthesiologist >â3 and indication for DBE of GI bleeding were independent risk factors for post-DBE bleeding within 1 year. Conclusions Continued antiplatelet use at the time of DBE was not an independent risk factor for bleeding post-DBE at 60 days or 1 year of follow up.
ABSTRACT
Insulinomas are rare, with an annual incidence of 1-4 people per mission. Insulinomas are the most common functioning endocrine neoplams of the pancreas. Endoscopic ultrasound has both diagnostic and therapeutic yield in undifferentiated pancreatic tumors. We present a case of a recurrent insulinoma, refractory to surgical and medical management diagnosed with endoscopic ultrasound. Our case uniquely conveys a successful, alternative approach to addressing symptomatic insulinomas refractory to surgical or medical management through computed tomography-guided percutaneous ethanol-lipiodol injection.

BACKGROUND/AIMS: The number of cases with coronavirus disease 2019 (COVID-19) has exceeded seven million worldwide. However, the data describing the global prevalence of liver injury associated with COVID-19 is lacking secondary to the novelty of this ongoing pandemic. Therefore, we conducted a meta-analysis to determine the association between COVID-19 and liver injury. METHODS: A systematic literature search of indexed databases including, PubMed, Medline, and Embase databases from inception to 14 April 2020, was used to identify studies that reported data of liver chemistry in patients diagnosed with COVID 19. The overall prevalence of abnormal liver chemistry and relevant 95% confidence interval was used to estimate the pooled results studies. RESULTS: Sixty-four studies with 11 245 patients with COVID-19 were included. The pattern of abnormal liver enzymes was notable for higher aspartate aminotransferase (AST) than alanine aminotransferase (ALT) levels. The overall global prevalence of elevated AST, ALT, total bilirubin, gamma-glutamyltransferase (GGT), and alkaline phosphatase was 23.2, 21.2, 9.7, 15.0, and 4.0%, respectively. The prevalence of elevated AST was substantially higher among those with severe cases (45.5%) compared to non-severe cases (15.0%). Co-existing chronic liver disease presented up to 37.6% of patients with COVID-19. CONCLUSION: A fourth of COVID-19 patients had elevated liver enzymes and associated with disease severity. Our study may be used as a guide for clinicians and epidemiologists to proactively identify other sources of injury and illness in patients diagnosed with COVID-19. Intensive monitoring for liver injury may be needed in cases with severe COVID-19.

BACKGROUND: Lymphocytic esophagitis is a rare esophageal condition. Our knowledge of potential risk factors and treatment outcomes of lymphocytic esophagitis is limited. AIM: To investigate potential risk factors associated with the development of lymphocytic esophagitis and compare clinical characteristics and treatment outcomes of patients diagnosed with lymphocytic esophagitis to patients diagnosed with eosinophilic esophagitis. METHODS: This is a multicenter retrospective study. Lymphocytic esophagitis patients were identified based on pathology results between 1997 and 2019. Control groups consisted of patients with normal esophageal biopsies and patients diagnosed with eosinophilic esophagitis. Thirteen potential risk factors for lymphocytic esophagitis were analyzed using univariate and multivariate models including IBD, achalasia, hyperlipidemia, hypothyroidism, celiac sprue, CVID, H. pylori, thymoma, aspirin, opioids, ACE-I, metformin, and statin use. Comparative statistics were performed. RESULTS: Ninety-four adult patients with lymphocytic esophagitis, 344 with eosinophilic esophagitis, and 5202 control patients with normal esophageal biopsies were analyzed. Age older than 60 [adjusted odd ratio (AOR) 1.03, 95% CI 1.02-1.05, p = 0.001], aspirin use (2.7, 95% CI 1.4-4.9, p = 0.001), statin use (2.2, 95% CI 1.2-4.2, p = 0.01), or a diagnosis of achalasia (2.4, 95% 1.08-5.67, p = 0.03) were associated with lymphocytic esophagitis. Compared to eosinophilic esophagitis, lymphocytic esophagitis patients were more likely to respond to medical treatment (95% CI 2.54-12.8, p = 0.0001). CONCLUSIONS: Our data suggests that lymphocytic esophagitis is more likely to be found in older female patients and is significantly associated with achalasia, statin, and aspirin use. Compared to eosinophilic esophagitis, lymphocytic esophagitis is more likely to respond to treatment with medical therapy.
