Background and Aims: Sarcopenia (SP) is increasingly recognized as a poor prognostic factor for patients with Crohn’s disease (CD). We aimed to use radiographically-measured SP to determine a disease-specific definition and measure its association with CD-related outcomes. Methods: This retrospective study included adults with CD seen at our outpatient tertiary center between 2019 and 2021 who underwent a CT scan within 3 months of visit. Using axial cross-sectional measurements at the L3 vertebral level, skeletal muscle area was indexed to height to derive skeletal muscle index (SMI). Demographics, comorbidities, CD phenotype, and outcomes, including hospitalization at 1 year, were analyzed in univariate and multivariate models. Results: One hundred twenty-four patients with CD were included, with a mean age of 52.2±16.6 years and 53.2% (66/124) women. Overall, 33.1% (41/124) had SP based on sex-specific cutoffs with men representing 75.6% (31/41) of the sarcopenic population. In bivariate analysis, patients with SP had a higher likelihood of hospitalization (43.9% vs. 22.9% for non-SP, P =0.02) and penetrating CD phenotype (20.0% vs. 2.3% for non-SP, P <0.05). On multivariate regression, higher SMI was associated with decreased hospitalization, with each 10-unit increase in SMI conferring 0.54 lower odds (OR: 0.54 [95% CI: 0.32-0.92], P =0.02). Patients with higher SMI trended towards lower use of biologics (OR: 0.70 [95% CI: 0.45-1.09], P =0.12). Our novel SP definition derived from an IBD population performed similarly to definitions from the literature. Conclusion: Our study demonstrates the application of an automated algorithm for the quantification of body composition based on CT scan in patients with CD. SP and low SMI were associated with increased hospitalization at 1 year.

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.

INTRODUCTION: Use of the electronic health record (EHR) has become increasingly widespread. Higher EHR burden is associated with burnout, but this has not been specifically investigated among gastroenterology (GI) providers. METHODS: We retrospectively collected measures of EHR use for outpatient GI providers during a 6-month period. We compared metrics across provider sex, subspecialty, and training (physicians vs nonphysician providers [NPPs]). RESULTS: Data collected represented more than 16,000 appointments from 41 providers across the Division of Gastroenterology and Hepatology. Inflammatory bowel disease (IBD) and hepatology specialists spent more time per appointment in the EHR, clinical review, and outside regular hours compared with other subspecialists. NPPs spent more EHR time than physicians. DISCUSSION: IBD and hepatology specialists and NPPs may have disproportionally high EHR burden. More work is needed to understand differences in provider workload to combat burnout.

Abstract Background Early endoscopic evaluation of patients with ulcerative colitis (UC) enables assessment of disease activity and accurate diagnosis based on exclusion of other similarly presenting conditions including infections. Early endoscopy is also associated with improved outcomes of patients with active UC. The aim of this study was determining temporal trends in endoscopy in patients with UC over a 7-year period from 2012 to 2018. Methods Retrospective cohort study using the National Inpatient Sample 2012–2018. Patients admitted with ICD-9–10 principal codes for UC were included. Early endoscopy using flexible sigmoidoscopy (FS) or colonoscopy was defined as performed within 48 hours of admission. The primary outcome was trends in endoscopy timing. Secondary outcomes were inpatient morbidity, mortality, length of stay (LOS), and hospitalization charges/costs comparing patients undergoing early vs nonearly endoscopy using multivariable regression. Results Of 222 460 patients hospitalized with UC, 5900 (2.7%) underwent FS and 43 345 (19.5%) underwent colonoscopy. The rate of endoscopy increased from 3.9% (2.3% early) to 39.3% (23.3% early) from 2012 to 2018 (P &lt; .01). Early endoscopy was associated with statistically significant decreased mortality, shock, multiorgan failure, and intensive care unit odds, as well as decreased resource utilization and LOS. Conclusions In patients hospitalized with UC, early endoscopy rates were low but performed more frequently from 2012 to 2018. This may reflect increasing awareness of improved outcomes from earlier disease staging and/or diagnosis. Early endoscopy was associated with decreased resource utilization and hospitalization-related outcomes, highlighting the importance of early endoscopy in patients admitted with UC.
