Importance Ischemia-reperfusion injury contributes to graft dysfunction after liver transplant. Hypothermic oxygenated perfusion (HOPE) has been shown to improve liver function, but its benefit in extended criteria donors in a US population remains unclear. Objective To assess whether back-to-base portal-venous HOPE impacts outcomes after liver transplant in the US. Design, Setting, and Participants The Bridge to HOPE Trial is a multicenter, randomized, open-label trial with 1-year follow-up. The study took place at 15 US liver transplant centers and patients were enrolled between January 2021 and May 2023. Central assessment of complications and cholangiograms for nonanastomotic biliary strictures (NAS) was blinded to treatment arm. Participants included 219 recipients of extended-criteria donor livers after brain death (DBD) and after circulatory death (DCD) who were randomized 1:1 to HOPE after static cold storage (SCS) (n = 109) or SCS only (n = 110). Randomization was performed after liver inspection and acceptance for transplant. Data were analyzed from December 2024 to July 2025. Intervention After SCS and transport, livers underwent portal-venous HOPE until implant, using the VitaSmart HOPE System. Main Outcomes and Measures The primary efficacy end point was early allograft dysfunction (EAD). Other main outcomes included model for early allograft function (MEAF) score, hospital length of stay (LOS), patient and graft survival, and biliary complications. Additional post hoc analyses were performed. Results Overall, 219 patients (82 female [37.4%] and 137 male[62.6%]) were included (DCD, 57 of 219 [26%]) with 97% (212 of 219) completing 12-month follow-up. EAD incidence was 20.2% (22 of 109) with HOPE vs 37.3% (41 of 110) with SCS (rate difference, −17.1%; 95% CI, −27.2 to −7.0; noninferiority P < .001; superiority P = .005). HOPE treatment led to significantly lower MEAF mean (SD) scores (HOPE group, 4.28 [1.75]; control group, 4.82 [1.85]; mean difference, −0.54; 95% CI, −1.02 to −0.06; P = .03) and shorter median LOS (hazard ratio, 1.32; 95% CI, 1.01-1.73; P = .04). NAS on imaging and 1-year survivals were comparable between groups (patients: HOPE group, 106 of 109 [97.2%] vs SCS, 106 of 110 [96.4%]; graft: HOPE group, 104 of 109 [95.4%] vs SCS, 102 of 110 [92.7%]). Post hoc analyses showed numerically less graft loss due to NAS after HOPE (4 vs 1) and less major complications (Clavien-Dindo classification ≥IIIa) per patient, respectively. Conclusions and Relevance Back-to-base portal-venous HOPE was compared with SCS alone for extended risk DBD and DCD livers. The HOPE approach was safe and associated with reduced EAD, MEAF score, and LOS. These findings support the use of HOPE as a pragmatic strategy to improve early posttransplant outcomes.

Abstract Background Three-dimensional visualization and quantitative analysis of cerebral arteries on 3DRA are central to endovascular treatment planning, device selection, and cerebrovascular research. Manual segmentation is time-consuming and operator-dependent, yet no open-source deep learning model has been prospectively validated for this task on 3DRA. Methods A nnUNet v2 model was trained for binary cerebral artery segmentation on 400 consecutive 3DRA acquisitions from three angiographic systems, comparing four configurations across architectures and loss functions. The best-performing configurations were prospectively validated on 40 patients using a dual approach: quantitative metrics (DSC, clDice, HD95, ASD, Precision, Recall), and blinded expert qualitative evaluation by two interventional neuroradiologists assessing 12 arterial segments, a global quality score, and clinical usability across 40 test cases. Results The ensemble model achieved median DSC 0.917, clDice 0.932, and HD95 1.494 mm. Global quality scores were significantly lower for nnUNet v2 than for expert segmentations (median 4 vs 5, p<0.001), but nnUNet v2 segmentations were rated clinically usable in 88–90% of cases versus 95–98% for expert segmentations, without significant difference on the binary usability criterion. A consistent proximal-to-distal quality gradient was identified, with comparable scores at proximal arteries and the largest differences at distal arterial segments. Conclusion nnUNet v2 with topology-aware training provides clinically usable cerebral artery segmentations on 3DRA, prospectively validated through both quantitative metrics and structured expert qualitative assessment, and represents a reproducible open-source foundation for endovascular and research applications.

Importance Little is known about how factors external to the workplace, such as spousal support, influence physician attrition. Objectives To explore associations of spousal support among married/partnered physicians with both ‘hard’ attrition ((HA), considering leaving academic medicine within 2 years) and ‘soft’ attrition ((SA), having ever considered part-time work), before and after adjusting for demographic variables, burnout and satisfaction with work-life integration (WLI). Design This cross-sectional survey study was conducted among faculty physicians employed at Mayo Clinic. Outcomes and measures Survey items measured demographics, spousal support (five items), HA, SA, satisfaction with WLI (single-item measure) and burnout (two-item measure). Check-all-that-apply questions explored reasons for considering attrition. We investigated associations of spousal career support with attrition consideration using logistic regression analyses, adjusting for demographic variables then for WLI satisfaction and burnout. Results 739/2103 physicians responded (response rate 35.1%); 666 (90.1%) were married or partnered and responded to the HA question. 42.5% (283/666) reported considering HA and 60.9% of full-time employees (288/473) had ever considered SA. 65.5% (437/666) considered any attrition (AA). Respondents reporting more frequent spousal career support had lower odds of HA (OR 0.80, 95% CI 0.68 to 0.94, p=0.006), though this was not significant when considering AA (OR 0.85, 95% CI 0.71 to 1.01, p=0.07). Neither association was significant after adjusting for WLI satisfaction and burnout (OR 1.01, 95% CI 0.80 to 1.29, p=0.91 (HA), OR 1.10, 95% CI 0.86 to 1.37, p=0.45 (any attrition)). Conclusions While spousal support was no longer significantly associated with attrition after adjusting for WLI satisfaction and burnout, it may mitigate attrition.

Abstract Heart involvement in eosinophilia represents a rare entity with substantial cardiac morbidity and mortality. This disorder is often overlooked and diagnosed in its advanced stages. In a subgroup of patients with eosinophilic heart disease, peripheral blood eosinophilia may not be present, and the biopsy of the affected organ or tissue is essential to establish the correct diagnosis. In this clinical consensus statement, an expert consensus group reviews the epidemiology, aetiology, diagnosis, and management of eosinophilic heart disease. The aim of the document is to increase awareness about the cardiac involvement associated with eosinophilia in order to diagnose the disease in early phases and prevent deleterious heart damage and adverse outcomes of affected individuals. The spectrum of physiological and immunological derangements requires a multidisciplinary approach for optimal management of affected individuals.

Purpose To investigate the clinical features, treatments, and outcomes of patients with secondary orbital lymphoma. Major Findings In this cohort of 31 patients, 15 (48.4%) were female and 27 (87.1%) were white. Follicular lymphoma was the most common subtype (n = 13, 41.9%) and was more associated with unilateral disease compared to other subtypes (p = 0.01). Common presenting symptoms included a palpable mass (n = 17, 54.8%), eyelid swelling (n = 16, 51.6%), and ptosis (n = 12, 38.7%). Patients were most often diagnosed with Ann Arbor Stage IV lymphoma (n = 17, 54.8%) via incisional biopsy (n = 13, 41.9%). Radiation therapy (n = 9, 29.0%) was the most common initial treatment, and most patients received radiation (n = 19, 61.3%) and/or chemotherapy (n = 21, 67.7%). A majority of patients had final best corrected visual acuity (BCVA) within 1 line of initial BCVA (n = 19, 82.6%) and had no local recurrences (n = 21, 67.7%). However, complete remission was rare (n = 3, 9.7%), and systemic recurrence occurred in over half of patients (n = 18, 58.1%). Conclusions Follicular lymphoma was the predominant subtype of secondary orbital lymphoma in this cohort. Most patients with secondary orbital lymphoma presented with advanced disease where few achieved complete remission and more than half of the patients developed systemic recurrence despite majority retaining visual acuity.

Purpose: Neuromuscular ultrasound, including cross-sectional area measurements, adds diagnostic value to the clinical and electrodiagnosis evaluation of ulnar neuropathy at the elbow. Previously published reference values for ulnar nerve size vary widely. Our objective was to establish age-specific reference values for ulnar nerve cross-sectional area at multiple sites in asymptomatic adults for our laboratory. Methods: Healthy adult subjects without neuromuscular symptoms or disease were recruited from our tertiary referral electromyogram laboratory and staff. Ulnar nerve cross-sectional area measurements were made in short axis at the wrist, forearm, cubital tunnel, retrocondylar groove, 2 cm proximal to the medial epicondyle, and mid-upper arm with the elbow flexed to 90°. Dynamic neuromuscular ultrasound evaluated for subluxation and dislocation at the medial epicondyle. Results were stratified by age group (younger than 40, 40–60, and older than 60 years) with at least 20 subjects per sex per group, as well as by sex, body mass index, and handedness. The upper limit of normal was established as two standard deviations above the mean. Results: One hundred forty-two subjects (ages 18–84, mean 47.7 years) were included. Cross-sectional area significantly increased with age at all sites except the wrist. Cross-sectional area cut-offs at the retrocondylar groove were 10.0, 10.9, and 11.4 mm 2 , respectively, by age group. Ratios comparing retrocondylar groove and cubital tunnel to arm and forearm were calculated. Thirty-two percent had subluxation or dislocation in at least one limb. Conclusions: Age-specific cross-sectional area cut-offs and ratios may facilitate a more nuanced interpretation and diagnostic value when used in conjunction with clinical and electrodiagnosis evaluation of ulnar neuropathy at the elbow.

Purpose: To determine the clinical utility of the assessment of preoperative orbital compliance in predicting the amount of postoperative proptosis reduction in patients with stable-phase thyroid eye disease who undergo orbital fat decompression surgery. Methods: A retrospective chart review was conducted of stable-phase thyroid eye disease patients who underwent orbital fat decompression by a single surgeon. Orbital compliance was measured preoperatively as axial globe displacement (in millimeters) using a Hertel exophthalmometer. Displacement ≥2.5 mm was classified as high compliance and <2.5 mm as low compliance. Radiographic thyroid eye disease type, preoperative proptosis, and intraoperative fat volume removed were recorded. Linear regression analysis determined whether orbital compliance independently predicted postoperative proptosis reduction. Levene’s test assessed variability between groups. Results: Forty-six orbits from 24 patients were included, 15 orbits with low compliance and 31 with high orbital compliance. Patients with high orbital compliance had a mean postoperative proptosis reduction of 3.19 mm (range 0.5–6.0 mm) while patients with low orbital compliance had a mean proptosis reduction of 2.67 mm (range 2.0–3.5 mm). On average, higher preoperative orbital compliance led to 0.959 mm greater proptosis reduction compared with low orbital compliance, when accounting for radiographic thyroid eye disease type and volume of fat removed intraoperatively ( p = 0.048). Variability in proptosis reduction was higher among the high orbital compliance group ( p = 0.00085). Conclusions: Higher preoperative orbital compliance results in greater proptosis reduction. However, patients with high orbital compliance have greater variability in proptosis reduction, suggesting that surgical outcomes are less predictable among these patients.

Abstract Background Traumatic brain injury (TBI) in older adults is associated with high mortality and poor functional outcomes. However, optimal management remains uncertain, as evidence comparing surgical and medical strategies is limited, heterogeneous, and extrapolated from younger populations. We conducted a systematic review and meta-analysis to compare outcomes between surgical and medical management in this population. Methods PubMed, Embase, and Web of Science were searched from database inception to December 8, 2025. Studies including adults aged ≥60 years with TBI comparing surgical versus medical management were included. The primary outcome was favorable neurological outcome, while secondary outcomes included hospital length of stay (LOS) and mortality. Pooled estimates were calculated as risk ratios (RR) and mean differences (MD) using random-effects models with restricted maximum likelihood and Hartung–Knapp adjustment. Results Sixteen cohort studies comprising 132,823 patients were included. Surgical management was not associated with improved favorable neurological outcomes at discharge, 3, 6, or 12 months. However, it was associated with longer LOS (MD = 6.35 days, 95% CI: 2.55 to 10.14; p < 0.01). No differences were observed in in-hospital, 30-day, 3-month, 12-month, or 24-month mortality. Notably, surgical management was associated with a reduction in 6-month mortality (RR = 0.68, 95% CI: 0.51–0.92; p = 0.02). Conclusions In older adults with TBI, surgical management was associated with reduced 6-month mortality and longer hospital LOS, but not with improved functional outcomes, highlighting a dissociation between survival and recovery. This dissociation has implications for clinical decision-making and patient and family counseling. Individualized decision-making that incorporates frailty, comorbidities, and potential reversibility of injury is essential, rather than relying solely on age. While this study represents the best available comparative evidence to date on surgical versus non-surgical management in older adults with TBI, findings should be interpreted with caution due to heterogeneity and low to very low certainty of the evidence. High-quality randomized controlled trials are needed to better define the role of surgery in this population.
