OBJECTIVE Chordomas are rare, locally aggressive primary neoplasms. Resection with negative margins is the primary recommended therapeutic approach, while adjuvant radiotherapy and chemotherapy can also play a role in their treatment in certain situations, including lesions with positive margins or those that are poorly differentiated or dedifferentiated. Cervical spine chordomas pose significant surgical challenges given their proximity to critical anatomical structures and the mechanical constraints of the cervical spine. In the current case series, authors aimed to explore the clinical and patient-reported outcomes (PROs) of the surgical treatment of cervical chordomas in a large multicenter cohort. METHODS This multicenter case series analysis utilized data from the prospectively collected Primary Tumor Research and Outcomes Network (PTRON) registry, from its inception (May 16, 2016) to data extraction (February 29, 2024). The study population was restricted to patients with histologically confirmed cervical chordomas involving levels C0–7, who underwent surgical treatment at one of the participating centers, and for whom both the initially planned and postoperatively pathologically confirmed surgical margins were documented. Patient demographics, tumor characteristics, surgical and adjuvant treatments, local recurrence–free survival (LRFS), overall survival (OS), and perioperative adverse events were retrieved. PROs included the Spine Oncology Study Group Outcomes Questionnaire version 2.0 (SOSGOQ2.0), EQ-5D, and SF-36 version 2.0 (SF-36v2). RESULTS Thirty-eight patients were identified, 12 of whom underwent true en bloc resection (EBR), 18 of whom underwent deliberate intralesional resection, and 8 of whom underwent EBR after intralesional surgery or in whom EBR failed. True EBR led to better LRFS (92% vs 83% vs 63%, respectively) and OS (83% vs 39% vs 50%, respectively). Surgical adverse events within 1 year were more frequent with true EBR (100% vs 39% vs 75%, respectively). EQ-5D, SOSGOQ2.0, and SF-36v2 showed improvement with true EBR, whereas the trends for PROs from the other groups were more variable. CONCLUSIONS This multicenter case series analysis provides critical insights into the clinical outcomes and PROs in the largest cohort of surgically treated cervical spine chordomas described to date. It underscores the importance and challenges of wide resection for oncological control. It establishes the associated morbidity and provides an overview of PROs following surgery. These findings contribute valuable evidence to inform shared decision-making and optimize patient care.

Abstract Background Recurrent pericarditis (RP) predominantly shows features consistent with IL-1-mediated chronic autoinflammatory disease (1-4). A recent analysis suggested that supplementing anakinra with colchicine incrementally reduced pericarditis recurrence vs. anakinra alone (5). Rilonacept (a weekly IL-1α and IL-1β cytokine trap with 6-week washout) prevents engagement with IL-1 receptor, inhibiting both IL-1α and IL-1β activity (6). The Phase 3 trial RHAPSODY demonstrated rilonacept efficacy in two independent analyses: Randomized Withdrawal (RW) and Long-Term Extension (LTE) periods (7,8). Purpose Assess long-term recurrence-free persistence with rilonacept as monotherapy in pts with RP during the combined RW and LTE periods of RHAPSODY. Methods Post-hoc analysis. Freedom from recurrence on rilonacept monotherapy was quantified using the Kaplan-Meier (KM) method from RW start (if randomized to rilonacept) or from initiation of bailout rilonacept (if randomized to placebo) until the end of treatment. Prespecified recurrence adjudication criteria were pericarditis pain (numerical rating scale [NRS]) ≥4 plus C-reactive protein (CRP) ≥1 mg/dL. Per RHAPSODY protocol, background therapies were discontinued during the Run-In Period before randomization. In pts treated with rilonacept, concomitant colchicine was not added during the RW period. In the LTE, 6.8% (5/74) of pts added colchicine: one for 2 days of chest pain without CRP elevation, 4 in the absence of chest pain, CRP elevation, or recurrence; these 5 pts were censored in the KM curve at 6 days after last rilonacept dose or at colchicine initiation (whichever was first). One additional pt added colchicine prophylactically before an intentional rilonacept treatment interruption for elective cardiac surgery and experienced a recurrence after this interruption; this pt was not censored from the recurrence-free persistence analysis at colchicine initiation in order to capture this event. Results 74 pts (mean [SD] age 43.9 [15.7] years, 83.8% idiopathic pericarditis, mean [SD] disease duration 2.5 [3.2] years) were analyzed over three years. Rilonacept was well tolerated. Recurrence-free persistence was 95.9% (n=71/74) while receiving rilonacept as monotherapy (Figure 1). The three observed adjudicated recurrences were each associated with temporary interruptions of 1-3 doses of rilonacept. Conclusions Rilonacept as monotherapy provided recurrence-free persistence over the three-year trial duration when used continuously without interruption; pericarditis recurrences occurred only after interruptions. These findings support evidence-based use of rilonacept as monotherapy, minimizing the need for adjunctive treatments and reducing polypharmacy in long-term RP management. Further investigations are warranted to address how to assess pts as candidates for long-term treatment with rilonacept and when to cease rilonacept treatment.

Abstract Background Recurrent pericarditis (RP) is an IL-1-mediated chronic autoinflammatory disease (1,2). The phase 3 trial RHAPSODY demonstrated that rilonacept (IL-1α and IL-1β cytokine trap), the first and only FDA-approved treatment for RP, was effective in treating RP not only as a third-line agent (3L; after corticosteroids) but also as a second-line agent (2L; instead of corticosteroids) and reduced recurrence risk as monotherapy (3). The REgiStry Of the NAtural history of recurreNt periCarditis in pEdiatric and adult patients (RESONANCE) has been collecting long-term combined prospective and retrospective data from US-based pericardial-disease-dedicated programs since 2020 (4). Purpose To assess the efficacy of rilonacept in RP in a real-world setting, extending the clinical trial findings of RHAPSODY. Methods Database cut-off (DCO) was 05 February 2025. Data on RP management were collected and analyzed from pts with ≥2 years of observation in RESONANCE. Disease duration at DCO was defined as time from RP diagnosis to either disease resolution (no disease flares while off all RP treatments for ≥6 months before DCO) or last follow-up (for pts with ongoing treatment at DCO). Pericarditis recurrences (investigator-assessed) were confirmed based on RP symptom data and/or objective findings. Annualized recurrence rates were calculated per RP treatment regimen as total pericarditis recurrences divided by total patient-years (PY) while receiving that treatment. Wilcoxon signed-rank test was utilized to analyze the significance in change of annualized recurrence rates before and after rilonacept initiation. Results At DCO, 81 pts had ≥2 years of follow-up data in RESONANCE; mean (SD) age was 51.0 (16.8) years; most (66.7%) were female; 84% had idiopathic etiology; median (Q1-Q3) disease duration was 3.1 (2.6-3.7) years; and median observation was 2.93 (2.54-3.38) years. Patient-year treatment exposures per treatment were: NSAIDS ± colchicine (n=79; 187.8 PY), corticosteroids (n=30; 61.1 PY), anakinra (n=1; 1.2 PY) and rilonacept (n=35; 72.8 PY). Of the 35 pts treated with rilonacept for any duration (median observation: 3.2 years; median time on rilonacept: 2.08 years), the most common reason for rilonacept initiation was chest pain/recurrence on prior treatment (n=28). The annualized recurrence rate while receiving rilonacept was significantly lower versus all combined prior lines of treatment (4.00 vs. 0.02 events per PY; p=0.002); this outcome was consistent across line of treatment for rilonacept use (2L: 3.73 vs. 0.06 events per PY, p=0.02; 3L: 4.14 vs. 0 events per PY, p<0.001; Table 1). Conclusions This first report of real-world outcomes from RESONANCE shows that rilonacept-containing regimens for RP as 1st, 2nd, or 3rd line therapy reduced recurrence risk over long- term (>2 year) treatment, supporting prolonged management during RP natural history.

Abstract Background Loss-of-function variants in TTN-encoded titin are the most common genetic cause of dilated cardiomyopathy (DCM). In addition, titin truncating variants (TTNtvs) are over-represented in early-onset atrial fibrillation (AF) and unexplained sudden cardiac arrest/death (SCA/SCD) suggesting that in rare circumstances TTNtvs may cause arrhythmias in a pre-cardiomyopathic electrical phase. Purpose To compare the prevalence of AF, sustained ventricular arrhythmias (VAs) and SCA/SCD between TTNtv-positive patients with genotype-positive but phenotype-negative (G+/P-) disease, non-dilated left ventricular cardiomyopathy (NDLVC) and DCM. Methods Retrospective review of 1,229 patients in our Arrhythmogenic/Dilated Cardiomyopathy Registry was used to identify those with TTNtvs in high proportion spliced-in (>90%) exons classified as pathogenic or likely pathogenic according to current American College of Medical Genetics and Genomics variant classification guidelines. Demographic, electrocardiographic, imaging and outcome data were extracted from the electronic record. After exclusion of those without satisfactory imaging data, each TTNtv-positive patient was classified as having G+/P- disease, NDLVC, or DCM according to the 2023 European Society of Cardiology Guidelines for the management of cardiomyopathies. The prevalence of AF, non-SCA major VA events (sustained VT and appropriate VT/VF-terminating ICD therapies), and SCA/SCD was then compared between the three left ventricular morphofunctional subgroups. Results Overall, 232 TTNtv-positive patients (mean age of 44 ± 17 years; 57% male) were included (average LVEF of 39 ± 17%; 32% with a history of AF; 23% with a history of non-SCA VA event and 6% with a history of SCA). Forty-nine (21%) were G+/P-, 45 (19%) had NDLVC, and 138 (59%) had DCM at the time of their most recent clinical evaluation. As expected, the prevalence of AF was higher in TTNtv-DCM patients when compared to both TTNtv-NDLVC [56/138 (41%) vs. 11/45 (24%); p=0.04] and G+/P- disease [56/138 (41%) vs. 5/49 (10%); p<0.001]. Similarly, the number of patients who experienced a non-SCA major VA event was higher in TTNtv-DCM than either TTNtv-NDLVC [44/138 (32%) vs. 6/45 (9%); p=0.01] or G+/P- disease [44/138 (31%) vs. 4/49 (8%); p<0.001]. Interestingly, no difference in the number of TTNtv-positive patients who experienced a SCA/SCD was observed across subgroups [2/49 (4%) for G+/P-; 2/45 (4%) for NDLVC; and 8/138 (6%) for DCM; p=ns for all comparisons]. Conclusion In patients with TTNtv substrates who were evaluated at a quaternary medical center, the prevalence of AF and major VA events correlates with left ventricular morphology/function with the greatest risk observed in those with DCM. However, the prevalence of AF and major VA events, including SCA, in TTNtv-positive patients with G+/P- and NDLVC disease is not trivial and highlights the ability of TTNtvs to present in a pre-cardiomyopathic electrical phase.

Abstract Background Cardiovascular disease (CVD) is the leading cause of death globally for both men and women, yet women remain historically underrepresented in cardiovascular clinical trials (CV trials), despite facing a disproportionately high burden of morbidity and mortality in many forms of CVD. Purpose We aim to determine the representation of women across a broad range of CV trials. Methods The participation of women in CV trials registered on ClinicalTrials.gov from 2017 to 2023 was systematically determined through the extraction of publicly available information. Data was extracted to identify the country of study, disease type, trial size, clinical intervention and age of the participants. We calculated the proportion of women and the ratio of number of females to male participants (F:M ratio) for each trial. The female participation to prevalence ratio (PPR) was estimated for each trial based on the relative prevalence of the disease by sex in the specified region. Results We identified 1,079 registered CV trials, which included 1,396,104 participants, of whom 571,641 (41.0%) were women. The median F:M ratio was significantly lower for studies on arrhythmia (0.5), coronary heart disease (CHD) (0.39), acute coronary syndrome (ACS) (0.32) and heart failure (HF) (0.51), but was higher for obesity (1.44) and pulmonary hypertension (PH) (2.86) CV trials. F:M ratio was higher for trials on lifestyle intervention (1.51) than for drug trials. PPRs were low for clinical trials on CHD (0.66), ACS (0.79), and stroke (0.74). There was a trend to increasing PPR from 2017 to 2023, p=0.056. Conclusion Representation of women in CV trials varies by disease state, region, intervention, and sponsor type. Better understanding of reasons for these differences may enable more tailored interventions to improve representation of women globally and across therapeutic areas.Figure 1 Figure 2

Abstract Purpose Clinician educators are essential to the academic medicine workforce, yet understanding how they assess their own teaching competencies is limited. The Clinical Educator Milestones (CEMs) guide growth across key educator domains, but their use and perceived relevance remain underexplored. This study aims to (1) evaluate clinician educators’ self-reported performance on the CEMs; (2) examine differences by career level, specialty, and experience; and (3) inform faculty development efforts through a clearer understanding of educators’ perceived strengths and gaps. Method Clinician educators from 9 US academic institutions completed a self-assessment rating their performance across 4 universal pillars and 11 educational theory and practice competencies on a 1- (novice) to 5- (expert) point scale in 0.5-point increments from August to November 2024. Descriptive statistics and mean difference tests were used to analyze variation across demographic and professional characteristics. Results A total of 484 responses to at least 1 CEM were received. Respondents rated themselves highest in commitment to professional responsibilities (mean [SD], 4.30 [0.68]), teaching and facilitating learning (mean [SD], 3.96 [0.74]), and professionalism (mean [SD], 3.93 [0.73]) and lowest in medical education scholarship (mean [SD], 3.11 [1.15]), program evaluation (mean [SD], 3.33 [1.03]), and the science of learning (mean [SD], 3.43 [1.10]). Statistically significant group differences were found by years of posttraining clinical experience (F2,413 = 16.87, P < .001, η2 = .076), years of teaching experience (F2,433 = 20.87, P < .001, η2 = .088), and academic rank (F2,403 = 13.96, P < .001, η2 = .065). Conclusions This study identifies key trends in self-perceived strengths and needs among clinician educators and highlights the limited awareness of the CEM framework. As institutions aim to build effective educator development systems, the CEMs can serve as a useful structure for tailoring support to individuals and identifying institutional needs.

Abstract Background The extravascular implantable cardioverter defibrillator (EV-ICD) was designed to avoid lead-related complications associated with transvenous systems and deliver features such as anti-tachycardia pacing (ATP) and reduced generator size that provide an advantage over a subcutaneous ICD (S-ICD). As such, the EV-ICD is an attractive alternative for younger patients with genetic heart diseases (GHDs) who are not in need of permanent pacing. Objective To examine the indications, complications, and the clinical outcomes of patients with GHDs who received an EV-ICD. Methods A retrospective review of the electronic record was done for all GHD patients evaluated in genetic heart rhythm and/or cardiomyopathy clinics who had an EV-ICD implanted between 1/2021 and 2/2025. Basic demographic, ICD indications, complications, and therapy data were then extracted for all study patients. Results Overall, 23 patients (35% female; mean age 39 ± 16 years; 61% with a disease-causative genetic variant; mean LVEF 57%) with an underlying GHD (hypertrophic cardiomyopathy in 9, arrhythmogenic cardiomyopathy in 8, idiopathic ventricular fibrillation in 3, dilated cardiomyopathy in 2, and long QT syndrome in 1) had an EV-ICD implanted. For the majority, an EV-ICD was implanted for primary prevention (15/23; 65%) and represented their first ICD system (21/23; 91%). The success rate of the procedure was 96% with only one abandoned procedure because of poor R-wave sensing. Inadvertent intraprocedural lead placement in the pericardial space occurred in 1 patient with previous thoracotomy and surgically placed epicardial lead without sequelae or need for revision. Over a mean follow-up of 8±9 months, the rate of complications was low (1/23; 4%) with one electrode displacement and this patient underwent defibrillation threshold testing (DFT), the device properly detected VF and emitted a successful shock 30 J. Thus far, 2 patients have received appropriate VT/VF-terminating therapies (3 ICD shocks, 0 ATP) with successful conversion to sinus rhythm. One patient died following an electrical storm. One patient had 3 inappropriate ICD shock for sinus tachycardia while exercising followed by 1 successful shock for VF. Conclusion In this early experience, EV-ICDs appear to be safe and effective in younger patients with genetic arrhythmogenic and hypertrophic cardiomyopathies. Future studies are needed to better understand the utility of EV-ICDs in patients with cardiac channelopathies and advantages of EV-ICDs over transvenous and S-ICD systems in patients with an array of sudden death-predisposing GHDs.

Abstract High-grade gliomas (HGGs) are aggressive tumors with poor outcomes and limited treatment options. Here, we combined genomic and transcriptomic tumor profiling with drug testing in a patient-derived 3-dimensional culture model to identify individualized treatments and predictive biomarkers. Activity of single agents targeting frequently dysregulated glioma pathways was relatively poor ex vivo and generally reflected historical patient data. However, compounds targeting PI3K, epigenetic, and survival/senescence signaling were effective in some cases. Drug sensitivity correlated with transcriptional rather than genomic features and suggested heterogeneity as a resistance mechanism. Bromodomain and extraterminal domain inhibition was particularly effective in tumors enriched in the mesenchymal transcriptional subtype, promoted proneural transition, and was overcome by upregulated PI3K signaling. Notably, combinations were largely effective, with 6 strategies exhibiting stronger efficacy than corresponding single agents in most cases (58-77%). This study identifies HGG vulnerabilities and associated biomarkers, resistance mechanisms, and effective combination strategies that warrant further clinical validation. Graphical Abstract

Abstract Background Relapsed medulloblastoma remains a significant therapeutic challenge as it is near universally fatal. The tumor microenvironment of medulloblastoma plays a critical role in tumor progression, influencing tumor growth, immune evasion, and therapeutic resistance. We hypothesized that defining tumor-immune interactions in diagnostic and relapsed medulloblastoma may uncover mechanisms of immune evasion and identify novel therapeutic targets. Methods We analyzed paired primary and recurrent RNA-sequencing data from 140 medulloblastoma patients to profile immune cell composition and validate spatial relationships within the TME. To identify key tumor-immune interactions, we developed a novel algorithm to detect receptor-ligand pairs using single-cell RNA-sequencing data. These interactions were validated across RNA and proteomic datasets. Their functional significance was empirically demonstrated in newly developed immunocompetent models of recurrent medulloblastoma that closely recapitulate the human disease. Results We observed a shift toward a heightened immunosuppressive TME at relapse. Using our algorithm, we identified biologically significant receptor-ligand interactions, most notably MIF-CD74, constitutively expressed at RNA and protein levels across medulloblastoma subgroups, at diagnosis and relapse. Disrupting MIF-CD74 interactions led to significant alterations in the tumor microenvironment, highlighting its functional significance. Conclusions Our multifaceted approach identified key tumor-immune interactions in medulloblastoma. Among these, MIF-CD74 was validated as a targetable interaction, demonstrating the utility of our integrative approach for identifying novel therapeutic targets across multiple tumor types.
