Abstract Erdheim-Chester disease (ECD) is a rare systemic histiocytic neoplasm, with cardiac morbidities, including cardiovascular (CV) risk factors and cardiac conditions, playing a significant yet poorly understood role in the disease burden. This study evaluated the prevalence, characteristics, and prognosis of ECD in patients with (ECD-C) and without cardiac involvement (ECD-noC) and compared the burden of cardiac morbidities with matched controls. Patients diagnosed with ECD between 1990 and 2021 at a tertiary center were included, with cardiac involvement centrally assessed using radiographic studies. Cardiac morbidities were compared with a control group without ECD, matched for age, sex, body mass index, and smoking history. Among 104 patients with ECD, 39 (37%) had cardiac involvement. Patients with ECD-C had higher rates of hypertension (67% vs 46%), hyperlipidemia (67% vs 40%), heart failure (36% vs 8%), and pericardial effusion (28% vs 2%) than those with ECD-noC. Compared with the matched non-ECD cohort, patients with ECD had higher prevalence of coronary artery disease (20% vs 7%), heart failure (18% vs 4%), and antihypertensive drug use (55% vs 40%). Notably, patients with ECD-C had inferior progression-free survival (PFS) from frontline therapy compared with patients with ECD-noC (5-year PFS, 28.3% vs 70.5%). These findings highlight the burden of CV risk factors and cardiac conditions in ECD, even without a clinical diagnosis of ECD-C. Importantly, this cardiac morbidity burden is substantial for patients with ECD-C compared with ECD-noC. Our findings highlight the need for comprehensive cardiac risk assessment and management strategies to improve patient outcomes.

ABSTRACT Transformed follicular lymphoma (tFL) is typically associated with chemotherapy resistance and a poor prognosis. There are limited data regarding outcomes after CD19‐directed chimeric antigen receptor T‐cell (CAR T) therapy in relapsed/refractory (R/R) tFL. A total of 923 adult patients with R/R tFL who received commercial CD19 CAR T therapy between 2017 and 2023 were identified in the Center for International Blood and Marrow Transplant Research registry. Median age was 64 years (range: 30–86) and median prior lines of therapy was 4 (range: 1–18). Most patients (78%) received axicabtagene ciloleucel, with 67% of patients having resistant disease at the time of CAR T infusion. At a median follow‐up of 25 months (range: 1–72) from CAR T infusion, the 2‐year overall survival (OS) was 57% (95% CI: 53–60) and progression‐free survival (PFS) was 43% (95% CI: 40–47). The 2‐year cumulative incidences of relapse or progression (rel/prog) and non‐relapse mortality (NRM) were 47% (95% CI: 44–51) and 9% (95% CI: 7–11), respectively. The overall response rate to CAR T was 76%, with a complete response rate of 63%. Grade ≥ 3 cytokine release syndrome (CRS) was observed in 7.1% and grade ≥ 3 immune effector cell–associated neurologic syndrome (ICANS) in 21.6% of patients. Multivariable analysis suggested that resistant disease status at the time of CAR T, use of bridging therapy, and high comorbidity index ≥ 3 were associated with inferior PFS and OS. Older age ≥ 60 significantly increased the risk of NRM. Our study suggests that CD19 CAR T is effective and safe for tFL.

Prostate cancer represents a significant health disparity among Black men, who experience higher rates of both incidence and mortality compared to other racial groups. Understanding the complex interplay of cultural, familial, and socioeconomic factors that shape health behaviors is essential for the development of effective interventions. This study sought to explore the lived experiences of ethnically diverse Black men with prostate cancer, focusing on how cultural context, family history, and spirituality influence health decisions and engagement with care. Through a secondary analysis of existing data, personal narratives from 32 Black prostate cancer survivors, primarily U.S.-born Black men, were examined to identify recurring themes that revealed the multifaceted challenges and motivations these men face. The analysis uncovered eight key themes that reflect a complex landscape, including medical distrust fueled by cultural perceptions and past negative experiences, the dual influence of family history on seeking early care versus hesitation, and the role of spirituality as a guiding force in health decisions. Additionally, financial constraints and limited access to comprehensive health information emerged as critical factors affecting engagement with preventive care. The findings underscore the need for culturally sensitive approaches that acknowledge the diverse experiences of Black men in their prostate cancer journey. By understanding the influence of family dynamics, spirituality, and socioeconomic challenges, future research can create targeted interventions that promote informed decision-making and help reduce disparities in prostate cancer outcomes.

Clonus is a disabling symptom of upper motor neuron dysfunction in patients with multiple sclerosis (MS). We report immediate termination of mechanically evoked clonus by epidural lumbosacral spinal cord stimulation (ES) in a 58-year-old man with secondary progressive MS. This observation was captured during training using video and skin surface electromyography of soleus muscle activity. ES immediately reduced mechanically evoked clonus duration and cycle count compared to trials without stimulation, as determined by a Kruskal–Wallis test ( p < 0.05, n = 2–3 trials), and reverted to baseline status when stimulation was off.
