Adhesion of E. coli to the urinary tract epithelium is a critical step in establishing urinary tract infections. FimH is an adhesin positioned on the fimbrial tip which binds to mannosylated proteins on the urinary tract epithelium via its lectin domain (FimHLD). FimH is of interest as a target of vaccines to prevent urinary tract infections (UTI). Previously, difficulties in obtaining purified recombinant FimH from E. coli along with the poor inherent immunogenicity of FimH have hindered the development of effective FimH vaccine candidates. To overcome these challenges, we have devised a novel production method using mammalian cells to produce high yields of homogeneous FimH protein with comparable biochemical and immunogenic properties to FimH produced in E. coli. Next, to optimize conformational stability and immunogenicity of FimH, we used a computational approach to design improved FimH mutants and evaluated their biophysical and biochemical properties, and murine immunogenicity using a bacterial adhesion inhibition assay. This approach identified an immunogenic FimH variant (FimH-donor-strand complemented with FimG peptide 'triple mutant', FimH-DSG TM) capable of blocking bacterial adhesion that is produced at high yields in mammalian cells. By x-ray crystallography, we confirmed that the stabilized structure of the FimHLD in FimH-DSG TM is similar to native FimH on the fimbrial tip. Characterization of monoclonal antibodies elicited by FimH-DSG TM that can block bacterial binding to mannosylated surfaces identified 4 non-overlapping binding sites whose epitopes were mapped via a combinatorial cryogenic electron microscopy approach. Novel inhibitory epitopes in the lectin binding FimH were identified, revealing diverse functional mechanisms of FimH-directed antibodies with relevance to FimH-targeted UTI vaccines., Competing Interests: I have read the journal's policy and the authors of this manuscript have the following competing interests: all authors were employees of Pfizer Inc during the conduct of this work and may hold Pfizer stock and/or stock options., (Copyright: © 2025 Silmon de Monerri et al.

Background: Cholangiocarcinoma (CCA) has rising incidence and mortality rates. Outcomes from combination systemic, loco-regional therapy (LRT) and liver transplantation (LT) are improving, but more granular data are needed to inform evidence-based management, including patient selection and immunosuppression., Methods: Patients with peri-hilar (PH) and intrahepatic (IH) CCA who underwent LT at a single center between January 2008 and February 2023 were reviewed retrospectively. Primary outcomes were overall survival (OS) and recurrence-free survival (RFS) with significance determined by Cox proportional hazards model., Results: During the study period, 53 patients underwent LT for either PH (n = 27), or IH (26). Cohort had mean age 58.5 years old (IQR, 47.0-63.0), body mass index (BMI) 25.9 (IQR, 22.9-30.0) kg/m 2 , and mean biologic MELD 9 (IQR, 7-17). Most frequent etiology was PSC (n = 12, 22.6%). Forty-nine patients (92.5%) received neoadjuvant therapy, including systemic (n = 48, 90.6%) and locoregional therapy (LRT) (n = 22, 41.5%), to which PH tumors were both most and least responsive (P = .03). On explant pathology, tumor were a median size of 3.5 cm and lympho-vascular invasion (LVI) was present in 13 (24.5%) cases. Median follow-up post-transplant was 910 days (IQR, 407-1509). Probabilities of OS and RFS at 3-years post-LT were 69.2% (95% CI, 56.9%-84.2%) and 57.4% (95% CI, 43.7%-75.4%). In multivariable analysis, OS was associated with tumor type and LVI, and RFS with age, BMI, PSC and LRT. After a median post-LT period of 38 days (IQR, 27-79.5), 39 (71.7%) patients started mTOR inhibition with lowered tacrolimus goal. Cox proportional hazard model showed significant association of OS with mTOR inhibition, though this was not validated by a time-dependent co-variate approach., Conclusions: In this single center cohort of CCA, post-LT outcomes were significantly greater for patients with IH tumors and no LVI. Immunosuppression with mTOR inhibition was not consistently associated with outcomes., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025 Elsevier Inc.

Background: Perihilar cholangiocarcinoma (phCCA) has excellent outcomes following liver transplantation (LT). Neoadjuvant radiation-based locoregional therapy is standard-of-care. Gemcitabine and cisplatin (gem/cis) combination systemic therapies have improved outcomes in advanced settings, but their efficacy pre-LT has not been studied., Methods: We review our experience following neoadjuvant gem/cis alone versus radiation-based approaches. Patients with phCCA undergoing LT at a single center between January 2008 and February 2023 were identified retrospectively. Neoadjuvant therapy was categorized as gem/cis systemic therapy (ST) alone, or any ST and radiotherapy (RT). Outcomes were posttransplant overall survival (OS), recurrence-free survival (RFS), waitlist time, and pathologic tumor response., Results: During study period, 27 phCCA patients underwent LT. One patient decompensated with neoadjuvant therapy and was excluded. Median age was 61 y (interquartile range, 53-68 y) and 14 (54%) were male. Of 26 patients, 12 (46%) received ST and 14 (54%) RT. Six RT patients received gem/cis ST. Median waitlist time was 199 d (interquartile range, 98-405 d) and did not differ by neoadjuvant regimen. Explanted tumors were predominantly T1 stage, without lymphovascular invasion or nodal involvement. Neither pathologic features nor percent tumor necrosis differed by regimen. OS probabilities at 1 and 3 y were 84% and 55% for the cohort. There was no significant difference in OS and RFS when stratified by regimen., Conclusions: Post-LT OS, RFS, waitlist time, and tumor response were similar in the 2 groups. Patients with phCCA who do not undergo RT may still be considered for LT under appropriate institution-based protocols that adhere to other established criteria., (Copyright © 2025 The Author(s).

Purpose of Review: Transplant oncology encompasses and utilizes liver transplantation (LT) in combination with other aspects of cancer care to offer improved long-term outcomes for patients with liver cancer, but not all patients have equal access and ability to undergo LT. Social determinants of health may negatively impact a patient's ability to receive liver-related oncologic care, including LT. This review highlights recent work exposing gaps in access to LT, including transplant oncology, and interventions to ameliorate these disparities., Recent Findings: Members of racial and ethnic minorities and indigenous groups, females, socioeconomically disadvantaged persons, and patients from rural areas are less likely to undergo LT. Recent studies have also described programs that have successfully mitigated some of the barriers in access to transplant oncology that these patients experience, including targeted outreach programs and access to virtual healthcare., Summary: Disparities in access to LT for liver cancer are increasingly well described, but additional research is needed to find effective ways to ameliorate these differences., (Copyright © 2024 Wolters Kluwer Health, Inc.

Objective: Data on treatment outcomes among minority populations treated with remdesivir are limited. We sought to evaluate outcomes among patients hospitalized with COVID-19 and treated with remdesivir among a predominantly Black and LatinX population., Methods: This was a retrospective cohort study of adult patients hospitalized with COVID-19 and treated with remdesivir at an urban hospital in Newark, NJ, between May 1, 2020, and April 30, 2021, prior to widespread COVID-19 vaccination uptake. We describe 28-day mortality by demographic, socio-economic, and clinical factors, including clinical status by World Health Organization's (WHO) 8-point Ordinal Scale for Clinical Improvement., Results: A total of 206 patients met study inclusion criteria (52% were male, 41% non-Hispanic Black and 42% Hispanic). Overall mortality at 28 days was 11%. Eighty-one percent of patients with baseline WHO status of 4 or greater recovered by day 14. Mortality was higher among those who were older (p = 0.01), those with underlying diabetes mellitus (p = 0.047), those with more severe illness on admission by WHO Ordinal Scale (WHO status ≥ 4), and those on concomitant tociluzimab or convalescent plasma use., Conclusions: We found that remdesivir was effective in treating most COVID-19 patients in our study. Traditional risk factors, such as advanced age and underlying co-morbidities, were associated with worse clinical outcomes and deaths., Competing Interests: Declarations.

Fate decisions during immune cell development require temporally precise changes in gene expression. Evidence suggests that the dynamic modulation of these changes is associated with the formation of diverse, membrane-less nucleoprotein assemblies that are termed biomolecular condensates. These condensates are thought to orchestrate fate-determining transcriptional and post-transcriptional processes by locally and transiently concentrating DNA or RNA molecules alongside their regulatory proteins. Findings have established a link between condensate formation and the gene regulatory networks that ensure the proper development of immune cells. Conversely, condensate dysregulation has been linked to impaired immune cell fates, including ageing and malignant transformation. This Review explores the putative mechanistic links between condensate assembly and the gene regulatory frameworks that govern normal and pathological development in the immune system., Competing Interests: Competing interests: The authors declare no competing interests., (© 2025.

Transcatheter tricuspid valve replacement (TTVR) has emerged as a promising intervention for the treatment of severe tricuspid regurgitation with complex valve morphology. This consensus document provides a comprehensive overview of the current state of orthotopic TTVR, focusing on patient selection, procedural details, and follow-up care. Clinical outcomes from initial studies and compassionate use cases are discussed, highlighting the effectiveness of TTVR in reducing tricuspid regurgitation, inducing reverse right ventricular remodeling, and enhancing patients' quality of life. This review paper also addresses potential complications and challenges associated with TTVR, such as new-onset conduction disturbances, bleeding complications, and afterload mismatch, and provides expert recommendations for the periprocedural management, anticoagulation strategies, and long-term follow-up. With the commercial approval of the first TTVR system in the United States and Europe, it intends to serve as a reference for clinicians and researchers involved in the evolving field of transcatheter tricuspid valve interventions., Competing Interests: Funding Support and Author Disclosures Dr Hausleiter has received research support and speaker honoraria from Edwards Lifesciences.

Background: The impact of tricuspid regurgitation (TR) on cardiac remodeling has not been thoroughly studied in a randomized controlled trial using advanced imaging., Objectives: The goal of this analysis was to provide comparative longitudinal changes in right heart remodeling using cardiac magnetic resonance and time-resolved functional computed tomography (4D-CT) in patients with symptomatic severe TR randomized to TriClip vs medical therapy (control)., Methods: TRILUMINATE Pivotal (Clinical Trial to Evaluate Cardiovascular Outcomes In Patients Treated With the Tricuspid Valve Repair System Pivotal) is an international randomized controlled trial in symptomatic patients with severe TR. A prospective imaging substudy was performed on TRILUMINATE Pivotal subjects at 10 sites. Cardiac magnetic resonance and 4D-CT were performed following dedicated imaging protocols at baseline and at 30 days, and a final 4D-CT at 1 year (all assessed by an imaging core lab)., Results: Sixty-nine randomized subjects (31 TriClip, 38 control) were enrolled. TR volume significantly decreased with TriClip at 30 days (P < 0.0001; 70% reduction). A strong association (r = 0.90; P < 0.0001) was observed between changes in TR volume and right ventricular end-diastolic volume at 30 days. Significant reductions in right ventricular end-diastolic volume (12% reduction; P < 0.001) and tricuspid annular area (11% reduction; P < 0.0001) were seen at 30 days and sustained through 1 year with TriClip. No meaningful changes were observed in the control group., Conclusions: Advanced imaging from the TRILUMINATE Pivotal imaging substudy demonstrated that TriClip effectively reduced TR. Significant cardiac remodeling was observed at 30 days and sustained at 1 year. With TriClip, the extent of cardiac remodeling was associated with the degree of TR reduction.

Background: Severe tricuspid regurgitation (TR) often causes substantial impairment in patient-reported health status (ie, symptoms, physical and social function, and quality of life), which may improve with transcatheter tricuspid valve replacement (TTVR)., Objectives: The authors performed an in-depth analysis of health status of patients enrolled in the TRISCEND (Edwards EVOQUE Transcatheter Tricuspid Valve Replacement: Pivotal Clinical Investigation of Safety and Clinical Efficacy using a Novel Device) II pivotal trial to help quantify the benefit of intervention to patients., Methods: The TRISCEND II pivotal trial randomized 400 patients with symptomatic and severe or greater TR 2:1 to TTVR with the EVOQUE tricuspid valve replacement system plus optimal medical therapy (OMT) or OMT alone. Health status was assessed with the Kansas City Cardiomyopathy Questionnaire and the 36-Item Short Form Health Survey. Changes in health status over 1 year were compared between treatment groups using mixed-effects repeated-measures models., Results: The analysis cohort included 392 patients, of whom 259 underwent attempted TTVR and 133 received OMT alone (mean age 79.2 ± 7.6 years, 75.5% women, 56.1% with massive or torrential TR). Patients had substantially impaired health status at baseline (mean Kansas City Cardiomyopathy Questionnaire Overall Summary Score [KCCQ-OS] 52.1 ± 22.8; mean 36-Item Short Form Health Survey physical component summary score 35.2 ± 8.4). TTVR+OMT patients reported significantly greater improvement in both disease-specific and generic health status at each follow-up time point. Mean between-group differences in the KCCQ-OS favored TTVR+OMT at each time point: 11.8 points (95% CI: 7.4-16.3 points) at 30 days, 20.8 points (95% CI: 16.1-25.5 points) at 6 months, and 17.8 points (95% CI: 13.0-22.5 points) at 1 year. In subgroup analyses, TTVR+OMT improved health status to a greater extent among patients with torrential or massive TR vs severe TR (treatment effect 23.3 vs 22.6 vs 11.3; interaction P = 0.049). At 1 year, 64.6% of TTVR+OMT patients were alive and well (KCCQ-OS ≥60 points and no decline of ≥10 points from baseline) compared with 31.0% with OMT alone., Conclusions: Compared with OMT alone, treatment of patients with symptomatic and severe or greater TR with TTVR+OMT resulted in substantial improvement in patients' symptoms, function, and quality of life. These benefits were evident 30 days after TTVR, continued to increase through 6 months, and remained durable through 1 year.

Background: Hepatocellular carcinoma (HCC) has a rising incidence and mortality in North America. Liver transplantation (LT) with adjunctive therapies offers excellent outcomes. However, HCC recurrences are associated with high mortality. We investigate whether adjuvant systemic therapy can reduce recurrence, as shown with other malignancies., Methods: Medical records of patients undergoing LT for HCC at a single center between January 2016 and December 2022 were retrospectively reviewed. Patients were stratified into 3 groups: (1) recipients of adjuvant sorafenib, (2) nonrecipients at high recurrence risk, and (3) nonrecipients at low risk by explant pathology features. The outcomes were overall survival (OS) and recurrence-free survival (RFS). Adjuvant sorafenib recipients were also propensity score matched 1:2 to nonadjuvant recipients based on recurrence risk features., Results: During the study period, 273 patients with HCC underwent LT and 16 (5.9%) received adjuvant sorafenib therapy. Adjuvant sorafenib recipients were demographically similar to nonrecipients and, on explant pathology, had greater tumor burden, lymphovascular invasion, and poorer differentiation (all P  < 0.001). Adverse events were observed in 12 adjuvant sorafenib recipients (75%). OS was similar among the 3 groups ( P  = 0.2), and adjuvant sorafenib was not associated with OS in multivariable analysis (hazard ratio, 1.31; 95% confidence interval, 0.45-3.78; P  = 0.62). RFS was significantly lower in sorafenib patients (hazard ratio, 6.99; 95% confidence interval, 2.12-23.05; P  = 0.001). Following propensity matching, adjuvant sorafenib use was not associated with either OS ( P  = 0.24) or RFS rates ( P  = 0.65)., Conclusions: In this single-center analysis, adjuvant sorafenib was not associated with OS. Recipients were observed to have shorter RFS, likely due to the increased prevalence of high-risk features, and sorafenib use was associated with high frequencies of adverse events., (Copyright © 2025 The Author(s).

Human pluripotent stem cells (hPSCs) exist in multiple, transcriptionally distinct states and serve as powerful models for studying human development. Despite their significance, the molecular determinants and pathways governing these pluripotent states remain incompletely understood. Here, we demonstrate that transposable elements act as sensitive indicators of distinct pluripotent cell states. We engineered hPSCs with fluorescent reporters to capture the temporal expression dynamics of two state-specific transposable elements, LTR5&#95;Hs, and MER51B. This dual reporter system enables real-time monitoring and isolation of stem cells transitioning from naïve to primed pluripotency and further towards differentiation, serving as a more accurate readout of pluripotency states compared to conventional systems. Unexpectedly, we identified a rare, metastable cell population within primed hPSCs, marked by transcripts related to preimplantation embryo development and which is associated with a DNA damage response. Moreover, our system establishes the chromatin factor NSD1 and the RNA-binding protein FUS as potent molecular safeguards of primed pluripotency. Our study introduces a novel system for investigating cellular potency and provides key insights into the regulation of embryonic development., Competing Interests: Disclosure and competing interests statement.
