Abstract Background Point-of-care testing (POCT) has expanded rapidly across healthcare systems, increasing both program scale and operational complexity. However, quantitative benchmarking data describing how POCT programs are structured and supported across institutions remain limited. Methods We conducted a cross-sectional survey to characterize POCT program support, including program scope, staffing, operational practices, governance, and challenges. The survey was distributed electronically through professional networks, and 93 institutional responses were analyzed. Descriptive analyses were performed, and derived metrics, including sites per point-of-care testing coordinator (POCC), were used to evaluate the relationship between program scale and staffing. Results POCT programs demonstrated substantial variability in scale, with wide ranges in the number of testing sites and operator populations. Adoption spanned multiple test categories, and many institutions reported use of multiple platforms for the same assays. Training, competency assessment, and quality management activities were primarily supported by laboratory staff and POCCs, with documentation frequently partially electronic. Median POCC staffing increased with program size; however, sites per POCC also increased significantly across program scale tiers (Kruskal–Wallis P < 0.001). Governance structures and operational responsibilities varied across institutions, and common challenges included staffing limitations, training and compliance burden, multisite coordination, and IT/connectivity constraints. Conclusions POCT programs are expanding in scale and complexity, but workforce capacity and governance structures have not scaled proportionally. This mismatch creates a cumulative and multiplicative operational burden. These findings provide benchmarking data to inform scalable staffing models, governance strategies, and infrastructure development for sustainable POCT program management.

Abstract High-risk breast lesions (HRLs) encompass a heterogeneous group of pathologies that coexist with an adjacent or synchronous malignancy, confer an increased risk of future breast cancer, or warrant surgical consideration because of upgrade potential or local behavior. Despite their clinical importance, management of HRLs remains variable. The American Society of Breast Surgeons (ASBrS) and the Society of Breast Imaging are collaborating to establish unified, evidence-based guidelines for managing these lesions. While these recommendations are currently in development, this review summarizes the existing literature and current guidance, including ASBrS recommendations, to provide context for multidisciplinary management. The article reviews the histopathologic features, imaging appearance, and management strategies for HRLs, including atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH), lobular carcinoma in situ (LCIS), flat epithelial atypia (FEA), papillomas with and without atypia, radial scar/complex sclerosing lesion (RS/CSL), mucocele-like lesion (MLL), desmoid tumor, and pseudoangiomatous stromal hyperplasia (PASH). Recent literature supports nonoperative management for specific radiologic-pathologic concordant lesions, particularly limited ADH, pure FEA, and pure RS, highlighting the important role of multidisciplinary discussion for personalized care. Lesions such as LCIS subtypes, papilloma with atypia, and MLL with atypia continue to warrant excision due to higher reported upgrade rates to malignancy. Beyond short-term management, HRLs such as ADH, ALH, and LCIS serve as biomarkers of long-term breast cancer risk, informing recommendations for surveillance, risk assessment, and chemoprevention counseling. Achieving a consensus among radiology, pathology, and surgical disciplines is essential to ensure oncologic safety while minimizing overtreatment in the era of precision breast care.

Abstract Oncogenic BRAF alterations occur in a subset of diffuse gliomas across WHO grades and are increasingly identified through modern molecular diagnostics. In addition to standard glioma therapies, targeted treatments are available for patients with BRAF-altered glioma supported by variable evidence spanning randomized trials, single-arm studies, and real-world evidence. This joint consensus review from the Society for Neuro-Oncology (SNO) and the European Association of Neuro-Oncology (EANO) synthesizes current knowledge on the diagnosis and management of BRAF-altered gliomas across age groups, tumor grades, and lines of therapy. Particular emphasis is placed on expert consensus in clinical scenarios where high-quality trial evidence remains limited. The review addresses rationale testing for BRAF alterations, selection, and monitoring of targeted therapies, management of treatment-related toxicities, approaches to resistance, and priorities for future research. It aims to provide practical, evidence-based guidance for clinicians while highlighting gaps to inform prospective studies.

Abstract Hepatic spheroids are widely used in bioartificial liver (BAL) systems, hepatotoxicology, and pharmacology due to improved functional stability compared with monolayer cultures. However, many existing methods rely on specialized equipment or static platforms that limit scalability and dynamic culture applications. Primary rat hepatocytes were cultured as three‐dimensional spheroids using a rocker‐based suspension system. Spheroid formation was evaluated across a range of rocking speeds (7–18 cycles per minute [cpm]) and inoculation densities. Spheroid morphology was quantified over time using two‐dimensional imaging. Functional performance was assessed by urea and albumin production on days 1, 4, 7, and 10. Spheroid formation efficiency was evaluated using volumetric modeling. Mean spheroid diameter decreased from 199 ± 41 μm at 7 cpm to 80.2 ± 17.6 μm at 18 cpm. The spheroid area was significantly influenced by both culture day ( p < 0.0001) and rocker speed, with significant differences observed across speeds at all time points ( p < 0.001, days 1–7). Mean spheroid area at 10 cpm was 13,750 ± 9051 μm 2 (day 1), 26,730 ± 8658 μm 2 (day 4), and decreased to 22,526 ± 8705 μm 2 (day 7). Urea production differed across speeds (ANOVA, p = 0.043), with peak performance at 12 cpm (median 3.47 μg/μg DNA) compared to 7 cpm (median 0.11 μg/μg DNA). Albumin production was 1086.8 ng/μg DNA on day 1 and 1534.4 ng/μg DNA on day 10. Urea production was 0.62 μg/μg DNA on day 1 and 1.25 μg/μg DNA on day 10. Median hepatocyte incorporation was 86% (range 73%–116%) by day 4. This rocker‐based method provides a simple, low‐cost, and scalable approach for generating hepatic spheroids with tunable size distributions under dynamic conditions. The system supports progressive functional maturation and is compatible with established scale‐up strategies, supporting its potential for translational applications.

Abstract The persistent global rise in atherosclerotic cardiovascular disease (ASCVD) challenges the effectiveness of current risk factor-based algorithms in primary prevention. Most myocardial infarctions occur in individuals without prior symptoms or recognized standard modifiable risk factors, underscoring the need to improve risk stratification. Coronary CT imaging, including coronary artery calcium scoring (CACS) and coronary computed tomography angiography (CCTA), enables direct non-invasive visualization of coronary atherosclerosis, supporting a shift from population-based prevention towards personalized, disease-based risk assessment and targeted preventive treatment. CCTA provides comprehensive evaluation of plaque burden, composition, stenosis severity, and high-risk plaque (HRP) features, thereby refining risk stratification and guiding personalized treatment decisions. The presence and total burden of coronary atherosclerotic plaque are considered the primary CCTA-derived markers for guiding preventive therapy, while noncalcified plaque burden and HRP features may support treatment intensification. Advances in CT technology, including photon-counting CT, and the application of artificial intelligence-based tools may further refine risk assessment by enabling accurate and reproducible plaque quantification and characterization. Although no randomized trials have yet demonstrated that CCTA-based screening improves clinical outcomes in asymptomatic individuals compared with standard care, the same is true of traditional cardiovascular risk scores. Three large ongoing randomized trials are currently evaluating whether CCTA-guided, personalized prevention strategies can reduce ASCVD events. The results are eagerly awaited and may redefine the role of CCTA in asymptomatic individuals.

Abstract This literature‐based systematic review and associated guidelines provide evidence‐based paradigms for the management of locoregionally recurrent rectal cancer (LRRC). This multispecialty committee included gastrointestinal radiation and medical oncology, gastroenterology, radiology, and colorectal surgery. As is the standard, the previously described American Radium Society Appropriate Use Criteria methodology for this project was followed rigorously, with the Population, Intervention, Comparator, Outcome, Timing, and Study Design framework and Preferred Reporting Items for Systematic Reviews and Meta‐Analyses methodology to assess the evidence. RAND/University of California Los Angeles consensus methodology (modified Delphi) was used to rate the appropriateness of treatment options. Published between January 1, 2013, and July 16, 2025, 116 peer‐reviewed trials provided the evidence: 10 were well‐designed randomized phase 2/3 trials, 29 were moderately well designed trials that accounted for most common biases (matched cohort and phase 2), 76 trials had design limitations (retrospective), and one was a meta‐analysis. Clinical cases were created as examples to illustrate current acceptable management of LRRC. Treatment and prognosis are influenced by prior therapy and the site(s) and extent of LRRC. The ability to achieve a margin‐negative surgical resection is the ultimate determinant of survival and local control. Preoperative systemic therapy, radiation therapy, or a combination of the two can facilitate tumor downsizing and improve the likelihood of a margin‐negative resection. An individualized multidisciplinary approach is required to ensure the best outcome. Although this review does not suggest a major alteration of current practice, it provides reassuring evidence of the importance of combined‐modality therapy.

Background/Objectives: Thoracic aortic aneurysm (TAA) often results from structural degeneration of the aortic wall. Traditional management focuses on hemodynamic control using beta-blockers (BB) and angiotensin receptor blockers (ARBs). Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), originally developed for diabetes and weight management, may offer additional vascular protective benefits through anti-inflammatory, antioxidative, and matrix-stabilizing mechanisms. However, their role in reducing mortality and thoracic aortic dissection (TAD) risk in patients with TAA has not been evaluated in human populations. In this study, we aimed to assess the association between GLP-1 RA use and the risks of mortality and thoracic aortic dissection. Methods: We conducted a retrospective cohort study of adults diagnosed with TAA between 2018 and 2024 across three Mayo Clinic sites. Patients receiving GLP-1 RAs were compared with non-users using 1:1 propensity score matching. Outcomes included all-cause mortality, cardiovascular mortality, and incident TAD. Kaplan–Meier and Cox proportional hazards analyses were performed. Results: A total of 32,279 patients with TAA, with a median age of 68.0 [IQR: 59.0–76.0] and 70.7% male, were included in a 1:1 propensity score match. This yielded a balanced cohort of 588 GLP-1 RA users and 588 non-users. Through a median follow-up of 4.1 (2.2, 5.9) years, GLP-1 RA use was associated with significantly lower 5-year cumulative incidence of all-cause mortality (5.0% vs. 14.5%, HR: 0.31; 95% CI: 0.19–0.50; p < 0.001), cardiovascular mortality (1.9% vs. 5.5%, HR: 0.30; 95% CI: 0.13–0.70; p = 0.005), and TAD (0.9% vs. 4.0%, HR: 0.19; 95% CI: 0.06–0.60; p < 0.0004). Conclusions: GLP-1 RAs are associated with reduced incidence of all-cause mortality, cardiovascular mortality, and TAD incidence in patients with TAA. Prospective studies are needed to confirm these findings and evaluate effects on aneurysm progression.
