Abstract Multiple myeloma (MM) is a heterogenous cancer that remains mostly incurable. A unifying feature of MM cells is a highly interconnected network of transcription factors and co-factors that coordinate the activity of super-enhancers to enforce myeloma cell identity. Targeting this network offers a promising avenue for therapeutic intervention across genetically diverse myeloma sub-types. Using integrated molecular and functional genomic approaches we identified Menin as a key driver of oncogenic gene expression in MM cells. Menin and its co-factor KMT2A bind at super-enhancers and maintain expression of essential myeloma genes, including IRF4. We demonstrate that Menin inhibitors, which have recently been approved for treatment of acute myeloid leukaemia, are highly active in myeloma cell lines and in vivo models. Combining Menin inhibitors with other super-enhancer targeting therapies such EP300/CREBBP inhibitors or immunomodulatory drugs (IMiDs) overcomes epigenetic plasticity in cells resistant to single agent treatment.

Importance Currently, there are no standardized outcome domains or measures in clinical trials for facial aging. Heterogeneity in outcome domains and measurement instruments across clinical trials creates difficulty in directly comparing interventions, determining superior therapies, and developing high-quality meta-analyses. Objective To develop a core outcome set (COS) of essential domains to be reported in clinical trials evaluating the efficacy of interventions for facial aging. Evidence Review PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials, and CINAHL were searched from September 2005 to September 2015. An updated search of the same databases was performed from September 2015 to February 2026. Studies were included if (1) they were randomized clinical trial or controlled clinical trial in design, (2) they assessed the efficacy or safety of an intervention for facial aging, (3) they were published in English, and (4) they involved human participants. Complementary sources, including patient interviews, were used to capture further relevant outcomes. Two rounds of Delphi surveys, followed by consensus meetings, were used to identify outcome domains considered most important by both patient and physician stakeholders. Findings The final COS consists of 6 outcome domains: (1) overall convenience of treatment; (2) time to return to normal work and social activity; (3) overall assessment of focused area of treatment (at the point in time when treatment is expected to provide peak benefit); (4) duration of treatment effect; (5) severity of persistent local or systemic adverse events, including pigmentary change, skin texture change, delayed healing, scarring, and serious adverse events; and (6) patient satisfaction with treatment. Conclusions and Relevance The 6 outcome domains identified through a Delphi consensus are recommended for reporting in future facial aging trials to ensure that outcomes that matter most to patients and clinicians are measured and that results are comparable across interventions.

ABSTRACT First‐line therapy for mantle cell lymphoma (MCL) represents a critical opportunity for clinical benefit via sustained complete response. We conducted a phase 2 multicenter trial in the academic and community cancer research united (ACCRU) network, testing a multitargeted 1st line regimen. CARiBOU (ACCRU‐LY‐1804) employs alternating VR‐CAP and R‐cytarabine with continuous acalabrutinib, in six 21‐day cycles, for previously untreated MCL. The primary endpoint was complete metabolic response (CMR) rate. Secondary endpoints included safety, feasibility of stem cell collection, proportion proceeding to ASCT, and progression‐free (PFS) and overall survival (OS). Peripheral blood measurable residual disease (MRD) was tested using the ClonoSEQ assay (Adaptive Biotechnologies). Of 41 patients enrolled, 39 (95%) responded to therapy, including 37 patients achieving CMR (90%). Two nonresponders discontinued therapy for toxicity early, prior to study‐defined restaging, and received alternate therapy. Undetectable MRD at a 10 6 threshold was achieved in 26/33 tested patients (79%), and 94% at 10 5 . 18‐month estimated PFS is 79% (95% CI 64%–97%), and OS is 96% (95% CI 88%–100%). Toxicities were primarily hematologic (grade 3 hematologic AE in 32 patients, [78%]). Twelve required platelet transfusions, and one grade 3 bleeding event occurred. Febrile neutropenia occurred in 4 patients, and 6 (14%) experienced SAEs. There were no treatment‐related deaths. CARiBOU is an efficient, highly effective outpatient 1st line MCL regimen, employing intermediate‐dose cytarabine and continuous acalabrutinib for 6 cycles. This multitargeted regimen addresses the biologic heterogeneity of MCL and permits flexible MRD‐guided decisions on consolidation and maintenance.

Purpose: Adolescents and young adults (AYAs) with cancer have unique physical, emotional, and social challenges. We aimed to identify key concerns among AYAs with cancer, evaluate pathways for connecting patients with resources, and inform the development of an AYA oncology program. Methods: This study was conducted at Mayo Clinic in Arizona and included English-speaking patients aged 18–39 years with recently diagnosed cancer. Participants completed a modified Needs Assessment Service Bridge questionnaire, which assessed patient-perceived needs with 39 items spanning 7 domains. An AYA nurse navigator discussed each participant’s results with them and connected them to the desired resources. Results: Of 52 eligible patients, 32 (62%) completed the questionnaire. Among them, 30 (94%) reported unmet needs in at least 1 domain and 19 (59%) reported unmet needs in 5 or more domains. The domains with the most frequently reported needs were health behaviors and wellness (81%), emotional health (72%), finances and everyday needs (59%), and work- and education-related assistance (56%). Younger participants reported more needs related to school life and scholarships/loans than did older participants. No significant differences were observed between the responses of men and women. Of 133 total needs identified by all participants, 93 (70%) were addressed by connecting patients to relevant resources. Conclusion: Systematic assessment of AYA needs and targeted connection to resources are essential for individualized and developmentally appropriate care. The current study identified key service gaps at our institution and will guide the continued evolution of our comprehensive AYA oncology program.

Abstract Genome sequencing of the heterogeneous primary mitochondrial disorders (PMD) frequently reveals variants of uncertain significance that require functional tests for diagnosis, and does not identify variants in all patients. We analyzed mitochondrial enzyme assays, blue native polyacrylamide gel electrophoresis (BN-PAGE) with in-gel activity staining, complex I assembly blot, and select protein abundances in fibroblasts of a case series of 204 PMD patients divided into functional classes, in comparison to 51 controls and 53 differential diagnostic conditions. Overall, sensitivity and specificity for respiratory chain enzyme assays were 46% and 93% respectively, for BN-PAGE 40% and 98%, for complex I assembly assay 49% and 99%. The overall sensitivity of all tests was 76%, specificity 93%, with positive predictive value 96% and negative predictive value 67%. Categories with high sensitivity were isolated complex deficiencies, nuclear DNA-encoded mitochondrial protein synthesis defects, co-factor defects, and mitochondrial amino-acyl-tRNA synthetase conditions when aided by protein abundance. Mitochondrial DNA mutations and maintenance disorders showed poor sensitivities. Secondary dysfunctions were rare. A complete battery of functional tests showed strong diagnostic clinical utility in fibroblasts. One sentence summary A combination of four mitochondrial functional tests to identify or confirm suspected primary mitochondrial disease in fibroblasts had good sensitivity and excellent specificity, well beyond what was perceived using enzyme assays only.

ABSTRACT Background Monoclonal gammopathy of thrombotic significance (MGTS) is a recently described chronic prothrombotic condition characterized by monoclonal anti-PF4 antibodies that are detected above the polyclonal antibody background in patient sera (i.e. present as monoclonal gammopathy of undetermined significance, MGUS). Due to conflicting data in the published literature on antibody clonality in heparin-induced thrombocytopenia (HIT), we evaluated clonality and abundance of anti-PF4 antibodies in HIT, including investigating whether an MGUS, if present in HIT, represents the causative anti-PF4 antibody. Methods Blood samples from 15 patients with HIT were subject to Platelet Factor 4-dependent antigen-based and functional tests. The unmanipulated serum antibody repertoire and isolated anti-PF4 antibodies were subjected to mass spectrometric evaluation. Results Two of the 15 HIT patients had an IgG MGUS. Notably, anti-PF4 antibodies were not synonymous with the MGUS antibody in either of the two patients. Eight of the 15 patients demonstrated monoclonal anti-PF4 antibodies, however, none of the anti-PF4 antibodies were detectable as an MGUS upon evaluation of the entire serum antibody repertoire, reflecting their low abundance. In the seven patients with multiple anti-PF4 antibodies, non-monoclonality was confirmed by analysis of deglycosylated antibody heavy chains. Conclusions Anti-PF4 HIT antibodies are monoclonal in approximately 50% of HIT patients, however, antibody abundance is low such that they are not detectable over the polyclonal IgG background (i.e. are MGUS-negative), differentiating HIT from MGTS. This observation helps explain the transient nature of HIT relative to the persistent prothrombotic state seen in MGTS.

Abstract INTRODUCTION White matter lesions on fluid‐attenuated inversion recovery magnetic resonance imaging (FLAIR‐MRI) reflect small vessel disease (SVD) and aid in identifying vascular contributions to impairment and dementia (VCID). Emerging diffusion MRI (dMRI) biomarkers are sensitive to early SVD but the lack of validated approaches for defining dMRI abnormality has limited their clinical utility. METHODS In 3934 participants (8749 observations) from a population‐based sample, we classified 9% as vascular cognitive impairment versus not (VCI+/VCI−) using abnormal FLAIR‐MRI and cognitive testing. We evaluated four distinct dMRI positivity criteria and assessed performance in an independent clinical sample. RESULTS The young referent criterion performed best and yielded an estimated prevalence of dMRI positivity aligned with pathology literature. About 40% of the population were dMRI positive, and these individuals had lower baseline cognition and faster longitudinal decline. Cutpoints were validated in an independent clinical sample. DISCUSSION The proposed dMRI abnormality framework can detect VCID and aid in identification of individuals at risk of VCI.

BACKGROUND: Surgical management of Crohn’s disease of the colon and rectum frequently requires total proctocolectomy with end ileostomy. There are limited data on the need for Crohn’s disease–directed therapy and the prevalence of recurrence after surgery. OBJECTIVE: To determine the risk of small-bowel Crohn’s disease recurrence and evaluate risk factors for postoperative recurrence after total proctocolectomy with end ileostomy. DESIGN: Retrospective cohort study. SETTINGS: Multistate tertiary health care system. PATIENTS: Adult patients with Crohn’s disease undergoing total proctocolectomy with end ileostomy between 2014 and 2023. MAIN OUTCOME MEASURES: The primary outcome was small-bowel Crohn’s disease recurrence. RESULTS: A total of 193 patients with a median age of 45 years (interquartile range, 34–61) were included. More than half of the patients (n = 102; 52.9%) had a history of small-bowel Crohn’s disease, and the majority (n = 134; 69.4%) received biologic therapy before surgery. The median follow-up time was 4.8 years (interquartile range, 2.0–7.6). Postoperatively, 30.6% of patients (n = 59) received biologic therapy. Thirty-five patients (18.1%) had small-bowel Crohn’s disease recurrence for an estimated 5-year recurrence-free rate of 80.2% (95% CI, 73.0–85.7). Seven patients (3.6%) developed small-bowel Crohn’s disease recurrence requiring surgery for an estimated 5-year surgical recurrence-free rate of 94.7% (95% CI, 89.0–97.5). On multivariable analysis, history of small-bowel Crohn’s disease (HR 2.17; 95% CI‚ 1.04–4.54) and diagnosis at age younger than 18 years (HR 2.31; 95% CI‚1.1–4.86) were associated with small-bowel Crohn’s disease recurrence. LIMITATIONS: Retrospective design and nonstandardized follow-up. CONCLUSIONS: Patients undergoing total proctocolectomy with end ileostomy for Crohn’s disease have approximately a 20% risk of small-bowel recurrence at 5 years but a low risk of requiring surgical intervention. Patients with a history of small-bowel Crohn’s disease and younger age at diagnosis have a higher risk of recurrence and may warrant consideration of more frequent surveillance and medical prophylaxis.

FACTORES DE RIESGO DE RECURRENCIA DE LA ENFERMEDAD DE CROHN DEL INTESTINO DELGADO DESPUÉS DE UNA PROCTOCOLECTOMÍA TOTAL ANTECEDENTES: El tratamiento quirúrgico de la enfermedad de Crohn del colon y el recto frecuentemente requiere proctocolectomía total con ileostomía terminal. Existe información limitada sobre la necesidad de terapia dirigida a la enfermedad de Crohn y la prevalencia de recurrencia tras la cirugía. OBJETIVO: Determinar el riesgo de recurrencia de la enfermedad de Crohn del intestino delgado y evaluar los factores de riesgo de recurrencia posoperatoria tras proctocolectomía total con ileostomía terminal. DISEÑO: Estudio de cohorte retrospectivo. ÁMBITO: Sistema de atención médica terciaria multiestatal. PACIENTES: Pacientes adultos con enfermedad de Crohn sometidos a proctocolectomía total con ileostomía terminal entre 2014 y 2023. PRINCIPALES MEDIDAS DE RESULTADO: El resultado primario fue la recurrencia de la enfermedad de Crohn del intestino delgado. RESULTADOS: Se incluyeron un total de 193 pacientes con una mediana de edad de 45 años (RIC, 34-61). Más de la mitad de los pacientes (n = 102, 52,9 %) tenían antecedentes de enfermedad de Crohn del intestino delgado y la mayoría (n = 134, 69,4 %) recibieron terapia biológica antes de la cirugía. El tiempo medio de seguimiento fue de 4,8 años (RIC, 2,0-7,6). Después de la cirugía, el 30,6 % de los pacientes (n = 59) recibieron terapia biológica. Treinta y cinco pacientes (18,1 %) tuvieron recurrencia de la enfermedad de Crohn del intestino delgado para una tasa estimada libre de recurrencia a 5 años del 80,2 % (IC del 95 %, 73,0-85,7). Siete pacientes (3,6 %) desarrollaron recurrencia de la enfermedad de Crohn del intestino delgado que requirió cirugía para una tasa estimada libre de recurrencia quirúrgica a 5 años del 94,7 % (IC del 95 %, 89,0-97,5). En el análisis multivariable, los antecedentes de enfermedad de Crohn del intestino delgado (HR 2,17; IC del 95%: 1,04-4,54) y el diagnóstico antes de los 18 años (HR 2,31; IC del 95%: 1,1-4,86) se asociaron con la recurrencia de la enfermedad de Crohn del intestino delgado. LIMITACIONES: Diseño retrospectivo y seguimiento no estandarizado. CONCLUSIONES: Los pacientes sometidos a proctocolectomía total con ileostomía terminal por enfermedad de Crohn tienen aproximadamente un 20% de riesgo de recurrencia en el intestino delgado a los 5 años, pero un bajo riesgo de requerir intervención quirúrgica. Los pacientes con antecedentes de enfermedad de Crohn del intestino delgado y menor edad al diagnóstico tienen un mayor riesgo de recurrencia y podrían requerir una vigilancia más frecuente y profilaxis médica.

ABSTRACT Objective To compare antigen removal processing with conventional sodium dodecyl sulfate decellularization for generating laryngotracheoesophageal scaffolds, focusing on preservation of extracellular matrix integrity and removal of immunogenic material. Methods Laryngotracheoesophageal complexes were harvested from C57BL/6 mice and processed using either antigen removal or sodium dodecyl sulfate‐based protocols. Scaffolds were analyzed for residual double‐stranded DNA content, collagen preservation, glycosaminoglycan retention, and ultrastructural integrity via histology, quantitative image analysis, and scanning electron microscopy. Results Both antigen removal and sodium dodecyl sulfate protocols achieved effective decellularization, with comparable dsDNA removal relative to native controls ( p = 0.001; p < 0.001). Antigen removal scaffolds demonstrated better collagen preservation compared to sodium dodecyl scaffolds, which exhibited marked collagen depletion (Muscle: Collagen I, p < 0.001; Collagen III, p < 0.01; Cartilage: Collagen I, p < 0.05; Collagen III, p < 0.01). Both antigen removal and sodium dodecyl sulfate groups showed significant glycosaminoglycan depletion compared with controls ( p < 0.001). Scanning electron microscopy confirmed superior ultrastructural preservation in antigen removal‐treated scaffolds, characterized by intact fibrillar architecture and lacunar morphology, while sodium dodecyl sulfate scaffolds demonstrated collapsed lacunae and irregular extracellular matrix organization. Conclusion Antigen removal processing generates laryngotracheoesophageal scaffolds with enhanced extracellular matrix preservation compared with conventional sodium dodecyl sulfate decellularization, while maintaining equivalent levels of antigen elimination. Retention of collagen and ultrastructure suggests antigen removal scaffolds may provide superior biomechanical and biologic performance for laryngeal tissue engineering. Although glycosaminoglycan depletion remains a limitation in both approaches, antigen removal scaffolds represent a promising pathway toward clinically translatable alternatives to immunosuppression‐dependent laryngotracheoesophageal repair. Level of Evidence Preclinical.

Abstract BACKGROUND Remote, smartphone‐based cognitive testing may improve access to cognitive assessments for Alzheimer's disease and related dementias. We evaluated the feasibility, reliability, and validity of unsupervised smartphone‐based cognitive tests in a registry‐based cohort. METHODS Adults without a record of cognitive impairment ( N = 1815; ages 18–92) were recruited from the University of California, San Francisco (UCSF) Brain Health Registry to complete three unsupervised smartphone cognitive testing sessions within 2 weeks. Reliability was assessed with correlations between sessions. Linear regression models tested associations of smartphone tasks with demographics, self‐ and informant‐rated cognitive concerns, and web‐based cognitive testing (Cogstate Brief Battery). RESULTS Adherence was high (82.2%) and usability favorable. Test–retest reliability was moderate to strong ( ρ ’s = 0.61–0.85, all p ’s < 0.001). Lower smartphone scores were associated with older age, lower education, cognitive concerns, and worse Cogstate performance. DISCUSSION Findings support the feasibility, reliability, and validity of remote digital assessments in adults without a record of cognitive impairment.
