Cholangiocytes are specialized epithelial cells that line the intrahepatic and extrahepatic biliary tree and play a critical role in bile modification, liver homeostasis, and response to injury. Cholangiocytes exhibit notable heterogeneity and plasticity, and their dysfunction is central to a spectrum of diseases targeting the bile ducts, collectively called cholangiopathies. These disorders include genetic, infectious, immune-mediated, and malignant diseases, with primary sclerosing cholangitis (PSC) representing one of the most complex and enigmatic of these disorders. PSC is a progressive, fibro-inflammatory disease of the bile ducts that is closely linked to inflammatory bowel disease, carries a heightened risk of cancer, and lacks any approved therapies. This review explores the biology of cholangiocytes, including their development, functional plasticity, and roles in secretion, absorption, and cellular signaling. We provide a detailed examination of cholangiopathies, particularly PSC, a complex cholangiopathy characterized by a paradoxical state of cholangiocyte senescence and hyperproliferation. We describe how immune cell dysfunction, the gut microbiome, genetic predispositions, and environmental factors converge to mediate PSC pathogenesis. We revisit the foundational technologies that empowered early discoveries and shaped the field as we know it today. We also explore how newer techniques such as organoid cultures, single-cell transcriptomics, epigenomics, and spatialomics have transformed our modern understanding of biliary pathophysiology. Finally, we provide an overview of existing rodent models of cholangiopathies and discuss their relevance to human disease. PSC remains therapeutically unaddressed, and thus ongoing multidisciplinary efforts are essential to developing targeted interventions. This review serves as a comprehensive resource for researchers and clinicians navigating the rapidly evolving landscape of cholangiocyte-centered liver disease research.

Circulating extracellular vesicles, proinflammatory/pro-oxidant metabolites, and history of preeclampsia may be used as biomarkers for diagnosis of early CAC in postmenopausal women.

Importance Transcatheter tricuspid valve replacement (TTVR) demonstrated superior outcomes over medical therapy in patients with severe tricuspid regurgitation (TR) in the Edwards EVOQUE Transcatheter Tricuspid Valve Replacement: Pivotal Clinical Investigation of Safety and Clinical Efficacy Using a Novel Device II (TRISCEND II) randomized clinical trial, and received regulatory approval in the US in 2024. Contemporary real-world data on its effectiveness and safety remain limited. Objective To evaluate 30-day clinical, echocardiographic, and health status outcomes of TTVR in real-world use. Design, Setting, and Population Retrospective cohort study of all consecutive patients who underwent TTVR in the US from February 2024 through March 2025 in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry. Patients had symptomatic, severe TR despite optimal medical therapy and TTVR was deemed appropriate by a heart team. Statistical analysis was conducted from September 2025 to February 2026. Exposure Device-enabled TTVR. Main Outcomes and Measures Thirty-day event rates (all-cause death, stroke, bleeding, new cardiac implantable electronic device [CIED] implantation, heart failure hospitalizations), TR reduction, and changes in health status (New York Heart Association [NYHA] functional class and Kansas City Cardiomyopathy Questionnaire Overall Summary [KCCQ-OS] score) are reported. Subgroup analyses examined the impact of baseline CIED status on outcomes. Results Among 1034 attempted procedures at 82 centers (mean [SD] age, 77.1 [10.6] years; 69.1% female; 73.2% NYHA functional class III/IV), a valve was successfully implanted in 1017 patients (98.4%). Mild or less TR was achieved in 98.4% of patients post procedure and in 97.7% at 30 days. At 30 days, all-cause mortality was 3.1%; stroke, 0.2%; bleeding, 7.9%; new CIED, 15.9% in CIED-naive patients; and heart failure hospitalization, 3.1%. There were significant improvements in NYHA functional class (class I/II, 82.7%; P < .001) and mean KCCQ-OS score (22.4 points; P < .001) from baseline to 30 days. There were no significant differences in 30-day mortality ( P = .47), heart failure hospitalization ( P > .99), and functional outcomes ( P = .55) when patients were stratified by baseline CIED status. Conclusions and Relevance Early US real-world experience with TTVR confirms safety and effectiveness in patients with severe TR. Thirty-day outcomes are consistent with the TRISCEND II pivotal trial, demonstrating acceptable safety, near-complete TR elimination, and significant health status improvements in an older, comorbid population. Rates of new CIED implantation and bleeding were lower than randomized clinical trial experience.

OBJECTIVE This study investigated the relationship between diabetes and the incidence of postoperative dysphagia following cervical spine surgery (CSS). METHODS A prospectively collected multi-institutional quality registry was retrospectively reviewed. Patients who underwent CSS were categorized on the basis of diabetes status, and correlations with preoperative and postoperative Eating Assessment Tool-10 (EAT-10) dysphagia questionnaire scores were assessed. Mixed-effects logistic regressions were performed to examine the impact of preoperative diabetes on postoperative dysphagia. RESULTS Of the 2001 patients who met the inclusion criteria, 400 (20%) had diabetes. Baseline dysphagia rates were not significantly different between groups (18% vs 14%, p = 0.08). Patients with diabetes had a significantly higher incidence of dysphagia at 1 month (66% vs 54%, p = 0.002), 3 months (39% vs 26%, p < 0.001), and 12 months (33% vs 24%, p = 0.004) after surgery compared to patients without diabetes. Including baseline dysphagia as a fixed effect, multivariable analysis indicated that diabetes was a significant predictor of postoperative dysphagia at 1 month (OR 1.46, p = 0.041) and 3 months (OR 1.63, p = 0.001) but not at 12 months (OR 1.21, p = 0.3). In patients with no baseline dysphagia, those with diabetes (329 of 400 [82.3%]) had a significantly higher incidence of new dysphagia than nondiabetics at 1 month (62% vs 50%, p = 0.003), 3 months (34% vs 21%, p < 0.001), and 12 months (27% vs 18%, p = 0.001). The mean change in EAT-10 scores between baseline and 12 months was significantly worse in patients with preoperative diabetes (2.440 ± 5.013 vs 1.688 ± 4.139, p = 0.025). Multivariable analysis indicated that diabetes was a significant predictor of new postoperative dysphagia at 1 month (OR 1.49, p = 0.040) and 3 months (OR 1.81, p < 0.001) but not at 12 months (OR 1.31, p = 0.2). CONCLUSIONS Diabetes is a significant risk factor for experiencing postoperative dysphagia following CSS. Diabetes correlated with higher incidence of dysphagia at all postoperative time points and was a strong independent predictor of postoperative dysphagia at 1 and 3 months.

Background: Rib remodeling, particularly targeting ribs 11 and 12, is gaining popularity in aesthetic body contouring to reduce waist circumference. Although rib manipulation techniques have been applied in other surgical fields, their use in plastic surgery has focused on achieving aesthetic goals. This study investigates the complications associated with rib remodeling techniques to enhance waistline contouring. Methods: A global cross-sectional survey was conducted among board-certified plastic surgeons who perform rib remodeling. Data from 2351 patient records (2018–2024) were collected, including demographic details, surgical information, and complications. Rib remodeling techniques assessed included surgical greenstick fracture modification and osteosynthesis. Results: The overall complication rate was 3.7% (86 of 2351 patients). Hyperpigmentation (17.4%), nonconsolidation (15.1%), burns (12.7%), and corset-related pressure ulcers (12.7%) were the most common complications. Major complications such as pneumothorax were rare (0.17%) and occurred only in RibXcar cases. Rib extraction/removal techniques had no reported complications, whereas Riboss had the lowest complication rate (1.96%) due to the use of osteosynthesis material for fracture stabilization. Conclusions: The incidence of complications related to the rib remodeling procedures in our study was 3.7%. However, some procedure-related complications—such as pneumothorax and hemothorax—can pose serious risks to the patient’s life. Nevertheless, when performed by a well-trained surgeon with an adequate learning curve, these procedures can be considered safe.

Abstract Background: Specialised knowledge in adult congenital heart disease is crucial but often lacking, particularly in resource-limited settings. The Global Conversations in Adult Congenital Heart Disease webinar series was initiated to provide accessible, global education via virtual platforms. Objective: This study evaluates the attendance patterns, participant demographics, knowledge outcomes, and audience feedback of the Global Conversations in Adult Congenital Heart Disease webinar series , analysing 19 monthly sessions conducted from October 2023 to April 2025. Methods: Registration data, session viewership, and total series reach were recorded. Demographics were collected per session. Pre- and post-session quizzes were used to assess changes in knowledge; scores from these independent groups were compared using the Mann–Whitney U test. Post-webinar surveys collected improvement suggestions. Results: Out of 1,956 registrants from 89 countries, 54.6% attended the sessions, representing 1,068 participants from 64 nations: mainly Colombia (30.9%), Peru (18%), the USA (14.1%), and Mexico (9.9%). Median quiz scores improved from 50% pre-session ( n = 120) to 100% post-session ( n = 108), a statistically significant gain ( p = 0.035). Notably, 29% had no prior adult congenital heart disease education. Most post-webinar survey respondents rated case presentations and discussions as excellent (75.0%) or good (20.1%). Qualitative feedback suggested areas for improvement included audiovisual quality, audience engagement, content delivery, and language accessibility. Conclusion: The Global Conversations in Adult Congenital Heart Disease webinar series successfully engaged a diverse international audience and showed significant differences in quiz scores between pre- and post-session independent groups, demonstrating the potential benefit and feasibility of virtual education in bridging gaps in adult congenital heart disease training, particularly in resource-limited countries.
