Acute-on-chronic liver failure (ACLF) has been associated with excellent post-liver transplant (LT) outcomes at 1 year; however, the impact of alcohol as ACLF precipitant, specifically alcohol-associated hepatitis (AH), and as etiology of chronic liver disease remains uncertain. This study aimed to assess the effect of alcohol as ACLF precipitant and chronic liver disease etiology (alcohol-associated liver disease vs. non–alcohol-associated liver disease) on posttransplant outcomes. We performed a retrospective study using the Multi-Organ Dysfunction and Evaluation for LT Consortium database and included 640 patients with ACLF who underwent LT across 15 transplant centers in North America. The primary outcome was 1-year posttransplant survival. We used logistic regression and Cox proportional hazards to compare posttransplant survival, mortality risk, and health care utilization, adjusting for age, ACLF grade, comorbid diabetes mellitus, chronic kidney disease, and HCC. The median follow-up from LT was 2.8 years (P25–P75, 2.2–5.5 y) for patients with AH-ACLF (n=42) and 3.1 years (P25–P75, 1.6–4.9 y) for patients without AH (n=598). No significant difference was observed in 1-year survival after LT in patients with AH-ACLF versus those without AH ( p =0.36). Patients with AH had significantly higher health care utilization evidenced by greater length of stay (28.5 vs. 19.0 d, p =0.004; adjusted linear estimate 16.89, 95% CI: 7.66–26.11, p <0.001), higher rates of rehabilitation placement (71.4% vs. 41.8%, p =0.002; adjusted odds ratio: 4.13, 95% CI: 2.04–8.89, p <0.001), and non-ambulatory status (39.0% vs. 21.0%, p =0.005; adjusted odds ratio: 4.54, 95% CI: 1.90–10.79, p <0.001). Compared with other etiologies, alcohol-associated liver disease was not associated with differences in 1-year mortality, mortality risk over time, or health care utilization, after excluding patients with AH as ACLF precipitant. While there were no differences in 1-year survival, AH-ACLF was associated with higher health care resource utilization compared with other ACLF precipitants. LT centers should ensure adequate resources are allocated for the management of these patients.

ABSTRACTIntroductionEsophageal dysmotility following metabolic bariatric surgery (MBS) may relate to decreased gastric compliance. We investigated high‐resolution esophageal manometry (HRM) and secondary peristalsis assessed by functional lumen imaging probe (FLIP) and their association with intragastric pressure after MBS.MethodsPatients undergoing HRM, FLIP, and barium esophagram (BE) after MBS were included. HRM metrics and proximal intragastric pressure at baseline (IGP baseline), during wet swallow‐induced esophagogastric junction relaxation (IGP EGJ opening), and following wet swallow‐induced esophagogastric junction opening with subsequent closure (IGP post EGJ closure) were measured. Contractile response was assessed during FLIP.ResultsForty patients (26 Roux en Y gastric bypass, 14 sleeve gastrectomy) with FLIP a median of 4 years after MBS, were identified. HRM was normal or consistent with ineffective esophageal motility (IEM) in 33 (82.5%) patients, while the contractile response on FLIP was abnormal (disordered/impaired, absent, or spastic reactive) in 28 (70%). Delayed emptying on BE was numerically more frequent with abnormal FLIP (6% vs. 0%, p = 0.08). IGP post‐EGJ closure (median 21.8 vs. 15 mmHg, p = 0.03) and ∆ IGP post‐EGJ closure—IGP baseline (median 4 vs. 0 mmHg, p = 0.02) were greater and predictive of abnormal contractility on FLIP (OR 1.11, 95% CI 1.00–1.2, p = 0.03 and OR 1.6, 95% CI 1.07–2.39, p = 0.003, respectively).DiscussionAbnormal contractility on FLIP, reflecting disordered secondary peristalsis, frequently occurs despite normal HRM findings after MBS. Secondary peristalsis may be associated with reduced gastric compliance, reflected by elevated proximal intragastric pressure. FLIP contractility could serve as an early marker for post‐MBS esophageal dysfunction.

Abstract Background We aimed to evaluate the effectiveness and safety of risankizumab (RZB) for Crohn’s disease (CD) in routine clinical practice. Methods We performed a retrospective review of a multicenter consortium of CD patients treated with RZB. Co-primary outcomes were week 12 clinical remission (Harvey Bradshaw Index [HBI] score of ≤4 or physician global assessment in those without HBI or with ileostomy) and 6-month endoscopic remission (Simplified Endoscopic Mucosal Assessment for Crohn’s Disease of 0-1 or absence of ulcers). Secondary outcomes included steroid-free clinical remission, clinical response, radiographic response, cumulative clinical and endoscopic remission rates at 6 and 12 months, and adverse events. Results A total of 309 patients were included (median disease duration 14 years [IQR, 6-24]; median follow-up 7.1 months [IQR, 4.1-10.3]). Most patients (85.8%) were advanced therapy (AT)-exposed, and 169 (54.7%) had prior ustekinumab (UST) exposure. Week 12 clinical remission rates were 49.7% (98/197) overall, and 44.2% (50/113) vs 57.1% (48/84) in UST-exposed vs naïve patients (P = .073). Among those with active disease on baseline endoscopy (n = 122) who had an available follow-up at 6 months, 52.4% (22/42) achieved endoscopic remission. Cumulative rates of clinical and endoscopic remission at 12 months were 65.0% and 49.5%, respectively. Cumulative 12-month endoscopic remission was 33.9% (19/56) in UST-exposed and 68.1% (32/47) in UST-naïve patients (P &lt; .001). Risankizumab was well-tolerated with no new safety signals identified. Conclusions In this large multicenter cohort of patients with CD, RZB was well-tolerated and effective in achieving favorable clinical and endoscopic outcomes in both AT-exposed and naïve populations, including those with exposure to UST.

Abstract Background and Aims Patients with inflammatory bowel disease (IBD) face increased risk of colorectal cancer (CRC). While the natural history of conventional dysplastic precursor lesions has been well-studied, the neoplastic potential of recently described nonconventional (NC) IBD-associated colonic mucosal lesions is unclear. We aimed to assess the incidence of antecedent NC lesions in patients with IBD who developed CRC. Methods A case-cohort study was performed to include patients with a diagnosis of IBD with or without CRC who underwent at least 2 surveillance endoscopic procedures at our institution between 1/1/2007 and 5/31/2023. NC lesions included serrated change and indefinite for dysplasia. Detection rates pre- and post-introduction of high-definition (HD) surveillance colonoscopy were compared. Results In total, 87 patients with IBD and CRC and 200 patients with IBD without CRC were identified. Of the cases, a majority had ulcerative colitis (n = 52, 60%), most commonly with extensive involvement (n = 46, 89%). Conventional (hazard ratio [HR] 2.18, 95% confidence interval [CI] 1.34-3.52) and NC (HR 2.28, 95% CI 1.59-3.26) lesions were associated with increased risk of CRC. Conventional lesions in the post-HD era appeared to have a stronger association with CRC (HR 2.79, 95% CI 1.62-4.77) than NC lesions (HR 1.62, 95% CI 0.86-3.06). Conclusions Both conventional and NC lesions seem to be associated with increased risk of CRC. Conventional lesions are more strongly associated with CRC than NC lesions in the post-HD era, but misclassifications in the pre-HD era may have resulted in a biased increased risk estimate for NC lesions.

AbstractBackgroundCochlear implants (CIs) are used to rehabilitate moderate to profound sensorineural hearing loss and stimulate the auditory system via a multichannel electrode array positioned in the scala tympani. Imaging evaluation of CIs is substantially degraded by metallic artifacts. Photon‐counting detector (PCD)‐CT has the potential to minimize such artifacts, though this has not been convincingly established in prior studies. This study compared the visualization of CI electrodes on PCD‐CT to conventional energy integrating detector (EID)‐CT.Materials and MethodsFive patients with CIs were prospectively recruited to undergo temporal bone imaging on both EID‐CT and PCD‐CT scanners yielding 2D and 3D Volume Rendering Technique (VRT) images. Three nonblinded neuroradiologists reviewed 2D and 3D VRT images for the ability to resolve CI electrode leads using a Likert scale. The average Likert scores of PCD‐CT versus EID‐CT were calculated for each reader for both 2D and 3D VRT images. (Likert scores 1–5 based on inferior to superior rating of PCD‐CT compared to EID‐CT). Inter‐rater agreement was assessed using Krippendorff's alpha with ordinal weights. ResultsFive patients underwent temporal bone CT for CI array evaluation. As evidenced by 5‐point Likert scales that were independently used by the three reviewers, this study demonstrated superior resolution of CI electrode array using PCD‐CT as compared to EID‐CT with an average score of 4.2 ± 0.8 for 2D images and 4.9 ± 0.4 for 3D VRT images.ConclusionsPCD‐CT is superior to EID‐CT in the visualization of CI electrodes, particularly in 3D VRT imaging.

Abstract Background & Aims: Sarcopenia is common in patients with liver disease and both sarcopenia and short telomeres are associated with mortality, however their relationship in patients with liver disease remains unknown. Methods: A cohort of 16,072 adults from the National Health and Nutrition Examination Survey from 1999-2006 was analyzed. Liver disease was defined by aminotransferases and classified into etiology-based categories. Sarcopenia was defined by dual-energy x-ray absorptiometry. All analyses were conducted separately on each multiple imputation data set and combined via Rubin’s rules. P-values for group comparisons were calculated by testing logistic regression parameter estimates. Cox proportional hazards regression was used for mortality analysis with mortality data available until 2015. Results:Sarcopenia was present in 9.5% of patients with liver disease. Age, race, income, education, physical inactivity, and certain medical comorbidities were associated with sarcopenia. Patients with liver disease and sarcopenia had significantly shorter telomeres than patients with liver disease without sarcopenia when unadjusted for age. The interaction between telomere length and sarcopenia was significantly associated with all-cause mortality. Conclusions: The implications of telomere length on all-cause mortality in patients with liver disease varied by age and sarcopenia status. Shorter telomeres appear to be more highly associated with increased mortality in older patients without sarcopenia.

Background: Remote patient monitoring (RPM) is an emerging focus in health care, and specialized programs may reduce medical costs, supplement in-office visits, and improve patient satisfaction. In this study, we describe the development, feasibility, and early outcomes of an RPM program for patients with decompensated cirrhosis. Methods: Forty-six patients were offered enrollment at the time of hospital discharge in the cirrhosis RPM program (CiRPM), of which 41 completed at least 30 days of monitoring. Participants were mailed remote monitoring equipment and a tablet to be used for patient-reported outcomes. Alerts were continuously monitored by virtual nursing staff who could perform targeted interventions. A cohort of historical controls (n = 74) was created for comparison using inverse probability of treatment weighting. Results: Patients were enrolled in the program for a mean of 83.9 days, with 28 (68%) completing the full 90-day program. Participants uploaded vital signs and responded to symptom-based questionnaires on 93% of the monitored days. On end-of-program surveys, over 75% of patients expressed satisfaction with the program. Gender, age, and MELD-Na were similar between CiRPM and weighted control groups. The 90-day readmission rate was 34% in CiRPM and 47% in weighted controls. In the CiRPM group, 12% of subjects had 2 or more admissions, compared to 37% in the weighted control group. Conclusion: This study demonstrates the feasibility of a cirrhosis-specific RPM program. Overall, patient satisfaction and utilization of the CiRPM was high. Future studies are needed to confirm the impact of RPM on the reduction of hospital readmissions in decompensated cirrhosis.
