Importance Transcatheter tricuspid valve replacement (TTVR) demonstrated superior outcomes over medical therapy in patients with severe tricuspid regurgitation (TR) in the Edwards EVOQUE Transcatheter Tricuspid Valve Replacement: Pivotal Clinical Investigation of Safety and Clinical Efficacy Using a Novel Device II (TRISCEND II) randomized clinical trial, and received regulatory approval in the US in 2024. Contemporary real-world data on its effectiveness and safety remain limited. Objective To evaluate 30-day clinical, echocardiographic, and health status outcomes of TTVR in real-world use. Design, Setting, and Population Retrospective cohort study of all consecutive patients who underwent TTVR in the US from February 2024 through March 2025 in the Society of Thoracic Surgeons/American College of Cardiology Transcatheter Valve Therapy Registry. Patients had symptomatic, severe TR despite optimal medical therapy and TTVR was deemed appropriate by a heart team. Statistical analysis was conducted from September 2025 to February 2026. Exposure Device-enabled TTVR. Main Outcomes and Measures Thirty-day event rates (all-cause death, stroke, bleeding, new cardiac implantable electronic device [CIED] implantation, heart failure hospitalizations), TR reduction, and changes in health status (New York Heart Association [NYHA] functional class and Kansas City Cardiomyopathy Questionnaire Overall Summary [KCCQ-OS] score) are reported. Subgroup analyses examined the impact of baseline CIED status on outcomes. Results Among 1034 attempted procedures at 82 centers (mean [SD] age, 77.1 [10.6] years; 69.1% female; 73.2% NYHA functional class III/IV), a valve was successfully implanted in 1017 patients (98.4%). Mild or less TR was achieved in 98.4% of patients post procedure and in 97.7% at 30 days. At 30 days, all-cause mortality was 3.1%; stroke, 0.2%; bleeding, 7.9%; new CIED, 15.9% in CIED-naive patients; and heart failure hospitalization, 3.1%. There were significant improvements in NYHA functional class (class I/II, 82.7%; P < .001) and mean KCCQ-OS score (22.4 points; P < .001) from baseline to 30 days. There were no significant differences in 30-day mortality ( P = .47), heart failure hospitalization ( P > .99), and functional outcomes ( P = .55) when patients were stratified by baseline CIED status. Conclusions and Relevance Early US real-world experience with TTVR confirms safety and effectiveness in patients with severe TR. Thirty-day outcomes are consistent with the TRISCEND II pivotal trial, demonstrating acceptable safety, near-complete TR elimination, and significant health status improvements in an older, comorbid population. Rates of new CIED implantation and bleeding were lower than randomized clinical trial experience.

Purpose: To determine the incidence of secondary IOL implantation in a cohort of children randomized to aphakia after unilateral congenital cataract surgery. Setting: Twelve clinical sites in the United States. Design: Randomized clinical trial. Data regarding secondary IOL implantation was collected retrospectively when patients were age 10½ years. Methods: We calculated the cumulative incidence of secondary IOL implantation in participants in the Infant Aphakia Treatment Study (IATS) who were randomized to aphakia to age 4½ years and were followed at age 10½ years. Results: Twenty-two (43%, 95% CI 29%,58%) of the 51 participants left aphakic to age 4½ years who had better than light perception vision at age 4½ years received a secondary IOL by age 10½. More than half (59%) of these were implanted by age 6 (Median 64.5 months, IQR 60,80). Secondary IOLs were implanted in children with good visual acuity (<20/40), as well as those with poor visual outcomes (>20/200) (39% and 44% respectively). Children who received a secondary IOL did not report less contact lens wear than those remaining aphakic (average of 94% of waking hours versus 90%, respectively). However, the proportion of children receiving a secondary IOL varied substantially by study center. Conclusions: Many children with unilateral congenital cataract who are initially left aphakic remain aphakic throughout the elementary school years. Practice patterns and family preference seem to be important drivers of the decision to implant a secondary IOL in these children.

BACKGROUND: Burnout remains prevalent among anesthesiology residents. Contributing workplace factors include limited control over scheduling, unpredictable hours, critical patient care needs, and other residency challenges. The Family Anesthesia Experience (FAX) is a program designed to educate residents and their support persons on wellness and residency demands. The focus of this multisite study was to evaluate the impact of FAX on first year clinical anesthesiology (CA1, ie, PGY2s) residents’ wellness. METHODS: This was a prospective evaluation study involving 15 US anesthesiology residency programs, 13 of which completed FAX. CA1 wellness was evaluated through surveys assessing perceived stress as the primary outcome, with exploratory outcomes including burnout, depression, psychological wellness, and social support. Additionally, changes in support persons’ understanding and knowledge of residency demands were tracked over time. The study included a historical control group of 302 CA1s (2019-2021) who did not participate in FAX, and an intervention group of 88 CA1s that participated in FAX (2021-2022). Statistical analyses compared changes in metrics between groups using linear mixed models and generalized linear models. RESULTS: Significant reductions in perceived stress were observed in the intervention group at 6 months post-FAX (mean change = –2.14, 95% CI, –3.95 to –0.34; P = .021, effect size = 0.58) relative to the control group, but there was no sustained difference at 12 months. Compared to the control support persons, intervention support persons reported increased understanding of residency demands, with significant improvements at 6 (mean change = 2.80, 95% CI, 1.12–4.48; P = .001, effect size = 0.77) and 12 (mean change = 2.59, 95% CI, 0.12–5.05; P = .039, effect size = 0.71) months. Improvement in support persons’ understanding did not predict changes in CA1 wellness outcomes. First generation physician residents reported lower family support at baseline but showed significant improvements in family support at 6 months (mean change = 3.05 points; 95% CI, 0.25–5.84; P = .033; effect size = 1.23) compared to their non first generation peers. CONCLUSIONS: FAX participation was associated with reduced perceived stress in residents up to 6 months post-intervention. First generation physicians experienced greater improvements in perceived family support compared to their non first generation peers. Our findings suggest that resident wellness may be enhanced by engaging both residents and their support persons in an educational wellness program that outlines the professional expectations and demands of anesthesiology residency training.

ABSTRACT Introduction Right ventricular pacing (RVP) has long been the standard therapy for bradyarrhythmias but may induce ventricular dyssynchrony and adverse cardiac remodeling. Physiologic pacing strategies that preserve the native conduction system, particularly left bundle branch area pacing (LBBAP), have emerged as promising alternatives. This study aimed to evaluate the comparative efficacy and safety of LBBAP versus RVP through an updated meta‐analysis. Methods Following PRISMA guidelines, we systematically searched PubMed, Cochrane CENTRAL, and ClinicalTrials.gov for relevant studies published through June 2025. Studies comparing LBBAP and RVP in patients undergoing pacemaker implantation were included. Pooled estimates were calculated using random‐effects models. Results A total of 40 studies comprising 8290 patients were included. LBBAP was associated with significantly shorter QRS duration compared with RVP (30 studies, n = 5510; MD −35.56 ms, 95% CI −41.88 to −29.24; p < 0.0001). Structural remodeling also favored LBBAP, with greater improvement in left ventricular ejection fraction (16 studies, n = 1693; MD +3.77%, 95% CI 2.43–5.12; p < 0.0001) and greater reduction in left ventricular end‐diastolic diameter (13 studies, n = 1666; MD −2.33 mm, 95% CI −3.59 to −1.07; p < 0.0001). Clinically, LBBAP was associated with lower heart failure hospitalization (RR 0.38, 95% CI 0.29–0.52; p < 0.0001) and reduced all‐cause mortality (RR 0.55, 95% CI 0.41–0.72; p < 0.0001), along with greater reduction in NT‐proBNP levels. Conclusion LBBAP provides superior electrical synchrony, improved cardiac remodeling, and favorable clinical outcomes compared with RVP, while maintaining a comparable procedural safety profile.

These NCCN Guidelines for Distress Management discuss the identification and treatment of psychosocial problems in patients with cancer. They are intended to assist oncology teams to identify patients who require referral to psychosocial resources and to give oncology teams guidance on interventions for patients with significant distress. These guidelines also provide guidance for social workers, certified chaplains, and mental health professionals by describing treatments and interventions for various psychosocial problems as they relate to patients with cancer. These NCCN Guidelines Insights summarize the panel’s most recent recommendations regarding standards of care for distress management in patients with cancer and implementation of these standards, including application of evidence-based care delivery models, such as the collaborative care model.

Abstract Specialized immune niches located in the stroma-tumor junction promote interactions between tumor-resident antigen-presenting cells and effector lymphocytes that are required for immunotherapy efficacy. We have hypothesized that this stromal-based immune crosstalk may be regulated by provisional extracellular matrix signals, analogous to the early-stages of wound healing where provisional matrix hosts robust immune activity. A cardinal provisional matrix remodeling event, the regulated proteolysis of the large proteoglycan versican (VCAN) generates an immunomodulatory fragment (matrikine), versikine, that engages adaptive immunity. We have previously shown that VCAN proteolysis correlates with T-cell infiltration across multiple solid and liquid cancers with the most immune-evasive cancers showing low to negligible rates of VCAN proteolysis (e.g., 0% in pancreatic adenocarcinoma). A recent clinical trial generated informative prospective data linking VCAN proteolysis with immunotherapy outcomes: patients whose metastatic colorectal tumors categorized as VCAN proteolysis-weak (VPW, 60% of cases) demonstrated inferior responses to checkpoint inhibition (CPI, pembrolizumab) and worse outcomes compared to VCAN proteolysis-predominant (VPP, 40%) cases. Leveraging these prospective trial data, we hypothesized that versikine therapy may rationally reverse the immunosuppression associated with the prevalent VPW phenotype. To tailor versikine therapy to specific human biomarker-stratified tumor phenotypes, we studied experimental models replicating partially T-permissive VPW-VCANlo human cancers and poor-prognosis, immune-exclusionary VPW-VCANhi cancers. Across VPW-like tumors, versikine promoted the stromal accumulation of CD40lghiIcoshiFoxp3neg Tfh-like CD4+ T cells that engaged dendritic cells (DC) and CD8+ T cells in “immune triads” even at baseline (prior to CPI), concurrently with the intratumoral expansion of activated CD8+ T cells expressing cytolytic molecules (granzymes, perforin). In VPW-VCANlo tumors, versikine delivered as LNP-mRNA or recombinant protein demonstrated monotherapy activity, dependent on Batf3-lineage DC and CD8+ T cells. When combined with single-agent CPI, versikine cured most VPW-VCANlo tumors with memory to tumor re-challenge. In VPW-VCANhi tumors, versikine synergized with combination immunotherapy modulating “mature DCs enriched in immunoregulatory molecules” (mregDC). Our data provide mechanistic rationale for the biomarker-stratified, therapeutic restoration of a provisional matrix-regulated immune signaling network to reverse resistance to CPI. Moreover, the data highlight the need to reevaluate prior approaches to globally disrupt tumor stroma in favor of biomarker-driven, pathway-focused harnessing of stromal signals that modulate anti-tumor immunity.

Abstract The CoMMpass study (NCT01454297) is a prospective, longitudinal observational study involving 1,141 newly diagnosed multiple myeloma (NDMM) patients. Bone marrow aspirates from the study participants were collected for comprehensive molecular characterization of tumor (using bulk RNA sequencing and whole genome sequencing) and tumor immune microenvironment using 3’ single-cell RNA sequencing (scRNA-seq). To support exploration of this rich multi-omic dataset, we developed CoMMpass Explorer (CE), an intuitive interactive platform that enables real-time analysis of clinical and genomic data from CoMMpass. A central feature of CE is cohort building, where users can filter and stratify patients by clinical, genomic, and survival data elements to create custom cohorts for analysis. CE provides five main views: Overall Summary for clinical feature distribution, Kaplan-Meier curves, and multivariate Cox proportional hazards models; Mutational Profile for visualizing and comparing somatic mutations; Tumor Profile for bulk differential expression and gene set enrichment; Immune Microenvironment for comparing cell type abundance and cell cycle dynamics between cohorts using scRNA-seq data; and Pseudo-Bulk, which aggregates single-cell expression by cell type to enable cohort-level comparisons of transcriptional programs using DEseq2. CE reproduces prior CoMMpass studies, including WEE1 expression being associated with poorer progression-free survival (Simhal, et al.) and different mutation frequencies between African American and European American patients (Manojlovic, et al.). We further demonstrate CE’s utility by interrogating the 2025 Consensus Genomic Staging (CGS) risk classification system (Avet-Loiseau, et al). We compared CGS high-risk (HR, n=249) vs. CGS standard-risk (SR, n=573) patients. HR patients have significantly worse progression-free survival, overall survival, and time to second-line therapy compared with SR patients. Univariate models recapitulated expected differences in the clinical features that define CGS risk. Bulk tumor RNA-seq and ssGSEA highlighted a more proliferative and genomically unstable transcriptional program in HR group, with upregulation of angiogenesis and cell-cycle-related pathways. In the immune microenvironment, monocytes were more abundant in the SR group. Pseudo-bulk RNA-seq of plasma cells showed overexpression of ANXA1, NSD2, IGF1R, MAF and related genes in HR. CE democratizes access to the CoMMpass multi-omic resource, allowing researchers to interrogate clinical and molecular heterogeneity. By enabling hypothesis generation and replication of published results, CE serves as a valuable tool for identifying prognostic biomarkers and meaningful patterns in gene expression, mutation profiles, and the immune microenvironment.

Abstract Amyotrophic lateral sclerosis (ALS) affects approximately 1.5 per 100,000 person-years in the United States, with a point prevalence of 3.8-5.6 per 100,000. ALS arises from the intersection of diverse pathogenic mechanisms spanning genetic mutations (C9orf72, SOD1, FUS, TARDBP), protein misfolding, RNA-metabolism defects, nucleocytoplasmic transport failure, prion-like propagation, mitochondrial dysfunction, and neuroinflammation. Increasing evidence from plasma proteomics and machine-learning studies indicates that these perturbations emerge years prior to clinical onset, highlighting an urgent need for mechanistically grounded patient stratification. At the same time, epidemiologic and molecular studies suggest unexpected parallels between ALS and cancer—including dysregulated DNA-damage responses, cell-cycle control, metabolic rewiring, and aberrant immune signaling—yet these cross-disease links remain fragmented and poorly mapped. We developed a multi-scale ALS-cancer knowledge graph integrating genetic, transcriptomic, proteomic, neuropathological, and longitudinal clinical datasets. Knowledge-graph completion approaches, including link prediction, graph embeddings, and embedding-based reasoning, were applied to infer missing edges and reveal latent modules connecting ALS-associated genetic lesions to oncogenic pathways implicated in genome instability, altered proliferation, metabolic remodeling, and immune dysregulation. This approach enables systematic interrogation of shared molecular programs across ALS and cancer, exposing under-characterized immune, metabolic, and axonal-transport circuits whose dual roles have been suggested but never comprehensively mapped. Predicted associations were evaluated using enrichment for established ALS genes, overlap with curated oncogenic and neurodegenerative pathways, and their ability to stratify patients by site of onset, progression rate, and biomarker signatures. These analyses generated patient-specific pathway fingerprints that (i) resolve dominant biological mechanisms across clinical subgroups, (ii) illuminate mechanistic intersections between neurodegeneration and malignancy, and (iii) prioritize repurposed oncology targets with potential relevance to ALS. This knowledge-graph framework provides a scalable and mechanistically informed strategy for classifying ALS patients, uncovering ALS-cancer pathway convergence, and supporting targeted therapeutic discovery across traditionally siloed disease domains.

Abstract Background: Multiple myeloma is the second most common adult blood cancer and remains incurable, despite recent advances. The IMWG/IMS recently published updated risk criteria, Consensus Genomic Staging (CGS), combining genomic events with clinical measures to identify high-risk patients (Avet-Loiseau, et al. JCO 2025). We applied CGS risk criteria to baseline samples from the Multiple Myeloma Research Foundation CoMMpass Study (NCT01454297), a prospective, longitudinal observational study that enrolled more than1100 participants between 2011-2017. Methods: We assessed patient risk following CGS criteria. Criteria 1: del(17p), with a cutoff of &gt;20% clonal fraction, and/or TP53 mutation. Criteria 2: an IgH translocation including t(4;14), t(14;16), or t(14;20) along with 1q+ and/or del(1p32). Criteria 3: monoallelic del(1p32) along with 1q+ or biallelic del(1p32). Criteria 4: beta-2 microglobulin &gt;= 5.5 mg/L with normal creatinine. Patients meeting one or more criteria were classified as High Risk. To test if risk showed association with genetic ancestry, we grouped patients into those with high African genetic ancestry and those with low African genetic ancestry. Genetic ancestry was measured using ADMIXTURE in comparison to 1000 Genomes. Results: We evaluated the CGS risk status of 877 CoMMpass patients, finding 69.2% (573/828) to be Standard Risk (SR) and 30.8% (255/828) to be High Risk (HR). HR patients showed worse progression-free survival (median PFS 26.3 months vs. 42.5 months; log rank test, p &lt; 0.0001) and overall survival (median OS 63.9 months vs. median not reached; p &lt; 0.0001). 10.6% (91/858) of patients met Criteria 1, 10.7% (93/873) met Criteria 2, 5.6% (49/877) met Criteria 3, and 8.7% (73/835) met Criteria 4. We found 14.2% (123/867) of patients to have high African-like genetic ancestry (AFR-high) and 85.8% (744/867) to have low African-like genetic ancestry (AFR-low). We observed significantly fewer HR patients within the AFR-high group (20%, 23/115) than in the AFR-low group (32.4%, 231/712) (Fisher’s exact test, p = 0.0065). The AFR-high group met HR criteria at a lower rate across all criteria, but only with Criteria 3 was the difference significant (p-value = 0.03). Higher levels of creatinine in AFR-high patients may have impacted meeting the normal creatinine requirement of Criteria 4. Conclusions: HR patients comprise 30.8% of CoMMpass subjects and show significantly worse PFS and OS than SR patients. AFR-high patients met HR criteria at a lower rate than AFR-low patients according to the CGS criteria. Clinical trials that utilize CGS criteria to determine patient eligibility may be challenged to enroll a representative patient population, including AFR-high patients. Screening and eligibility criteria should be carefully considered to mitigate potential enrollment disparities. Citation Format: Steven M. Foltz, Chaitanya R.

Abstract Professional identity is defined as the attitudes, behaviors, values, and experiences by which individuals define themselves in a professional role and is influenced by socialization during training and in the workplace. As professional identity develops and is integrated with one's personal identities, it allows an individual to think, act, and feel like a member of their chosen profession and to develop a sense of meaning, confidence, and satisfaction in their work. Conflicts may arise due to perceived differences between one's professional identity and the collective identity of the profession, resulting in stress, burnout, and attrition, all of which can negatively impact patient care and the collective identity of the genetic counseling profession. Using Social Identity Theory (SIT) as a theoretical framework to develop the semi‐structured interview protocol, recorded interviews were conducted with 50 genetic counselors who were purposefully sampled to ensure diversity of personal demographics (gender, race/ethnicity, sexual orientation, disability, and caregiver status), as well as years, settings, and roles in genetic counseling practice. Transcripts were coded and subjected to codebook thematic analysis using NVivo. Genetic counselors described their professional identity in terms of who they are (characteristics and attributes), what they do (actions and skills), and what they have (training and knowledge). The majority of participants had a multidimensional perspective of what it means to be a genetic counselor, noting the transferability of their skills to a broad set of roles and settings, which supported their sense of professional identity, particularly for those who were no longer seeing patients. Yet many expressed tension with the collective identity of the profession. Expanded opportunities for genetic counselors to work in new settings and roles require review and revision of key professional documents to ensure they are reflective of the collective identity of the genetic counseling profession.
