Intra- and Post-procedural Patient-reported Experience Measures and their Correlation with post-ERCP Adverse Events and Unplanned Healthcare Utilization.

Background and Study Aims Post-endoscopic retrograde cholangiopancreatography (ERCP) adverse events (AEs) are common, as is unplanned healthcare utilization (UHU). We aimed to elucidate potential associations between intra- and post-procedural patient-reported experience measures (PREMs) and post-ERCP AEs and UHU. Patients and Methods Prospective data from a multi-center collaborative were used. A validated 0-10 Likert-based PREM assessing intra- and post-procedural symptoms was applied to patients following ERCP and protocolized follow-up was performed at 30 days to identify AEs and UHU for reasons not meeting the definitions of any AE. Multivariable logistic regression was conducted using PREM domains as exposures and individual AEs and UHU as outcomes, with a priori selected patient- and procedure-related covariates. Test performance characteristics and odds ratios (ORs) and 95% confidence intervals (95% CIs) for each PREM domain were reported. Results From September 2018 through October 2023, 3,434 ERCPs were included. Post-procedural abdominal pain of >3 was predictive of pancreatitis (OR 3.71, 2.37-5.73), while a score >6 was strongly predictive of perforation (OR 9.54, 1.10-59.37). Post-procedural pain was also predictive of UHU within 30 days when used as a continuous predictor (OR 1.08 per point, 1.01-1.16). Post-procedural pain of >6 demonstrated high negative predictive values and specificities for post-ERCP AEs. Conclusions Patient-reported symptom scores from a simple Likert-based PREM at the time of discharge from ERCP are associated with presentations for pancreatitis, perforation, and UHU within 30 days. Applying PREMs post-ERCP could potentially prevent UHU and/or facilitate earlier management and improved outcomes for patients with post-ERCP AEs.

Fibroblast growth factor-2 regulates human cardiac myofibroblast-mediated extracellular matrix remodeling.

BACKGROUND: Tissue fibrosis and chamber remodeling is a hallmark of the failing heart and the final common pathway for heart failure of diverse etiologies. Sustained elevation of pro-fibrotic cytokine transforming growth factor-beta1 (TGFß1) induces cardiac myofibroblast-mediated fibrosis and progressive structural tissue remodeling. OBJECTIVES: We examined the effects of low molecular weight fibroblast growth factor (LMW-FGF-2) on human cardiac myofibroblast-mediated extracellular matrix (ECM) dysregulation and remodeling. METHODS: Human cardiac biopsies were obtained during open-heart surgery and myofibroblasts were isolated, passaged, and seeded within type I collagen matrices. To induce myofibroblast activation and ECM remodeling, myofibroblast-seeded collagen gels were exposed to TGFß1. The extent of ECM contraction, myofibroblast activation, ECM dysregulation, and cell apoptosis was determined in the presence of LMW-FGF-2 and compared to its absence. Using a novel floating nylon-grid supported thin collagen gel culture platform system, myofibroblast activation and local ECM remodeling around isolated single cells was imaged using confocal microscopy and quantified by image analysis. RESULTS: TGFß1 induced significant myofibroblast activation and ECM dysregulation as evidenced by collagen gel contraction, structural ECM remodeling, collagen synthesis, ECM degradation, and altered TIMP expression. LMW-FGF-2 significantly attenuated TGFß1 induced myofibroblast-mediated ECM remodeling. These observations were similar using either ventricular or atrial-derived cardiac myofibroblasts. In addition, for the first time using individual cells, LMW-FGF-2 was observed to attenuate cardiac myofibroblast activation and prevent local cell-mediated ECM perturbations. CONCLUSIONS: LMW-FGF-2 attenuates human cardiac myofibroblast-mediated ECM remodeling and may prevent progressive maladaptive chamber remodeling and tissue fibrosis for patients with diverse structural heart diseases.

End-Stage Liver Disease Models and Outcomes in Pediatric Patients Supported With Short-Term Continuous-Flow Ventricular Assist Devices.

Short-term continuous-flow ventricular assist devices (STCF-VADs) are increasingly being utilized in pediatrics. End-stage liver disease (ELD) models have been associated with outcomes in adult patients on mechanical circulatory support. We sought to determine the relationship between outcomes in children on STCF-VADs and three ELD models: model for end-stage liver disease-excluding international normalized ratio (MELD-XI; all) and MELD-XI (> 1 year), PELD, and a novel score, PedMELD-XI. All patients (< 19 years) supported with STCF-VADs, between June 2009 and December 2016 were included. The MELD-XI, PELD, and PedMELD-XI scores were calculated and their association with adverse events and a composite measure of death, major bleeding, and neurologic dysfunction was analyzed. Of 32 patients, median age was 0.57 years (interquartile range [IQR], 0.10-4.43), median weight was 7.15 kg (IQR, 3.68-16.53), 53.1% had congenital heart disease, and 53.1% were male. In total, 78.1% patients experienced an adverse event (78.1% a major bleed, 25.0% neurologic dysfunction, and 15.6% death). The median MELD-XI score was 11.17 (IQR, 9.44-30.01), MELD-XI (>1 year) 9.44 (IQR, 9.44-24.33), PELD 6.00 (IQR, 4.00-13.75), and PedMELD-XI -14.91 (IQR, -18.85 to -12.25). A higher MELD-XI for all ages (13.80 vs. 9.44, p = 0.037) and less negative PedMELD-XI (-14.16 vs. -19.34, p = 0.028) scores were significantly associated with bleeding and the composite outcome. PedMELD-XI was significantly associated with death (-12.87 vs. -16.84, p = 0.041) while a trend was seen for increased MELD-XI in all ages being associated with death (31.52 vs. 10.11, p = 0.051). Last, there was no association with the models and neurologic events. MELD-XI and PedMELD-XI were significantly associated with major bleeding and the composite endpoints with PedMELD-XI also being associated with death. These results suggest that ELD models can be used to predict outcomes in this specific patient population, however, further analysis in a larger population is required.
