ImportanceIntraocular pressure (IOP) reduction with phacogoniotomy (phacoemulsification plus goniosynechialysis plus goniotomy) was not less than that of phacotrabeculectomy for advanced primary angle-closure glaucoma (PACG) with cataract at 1-year follow-up, but longer-term outcomes are needed.ObjectiveTo investigate if phacogoniotomy is noninferior to phacotrabeculectomy for advanced PACG with cataract at 2 years.Design, Setting, and ParticipantsThis multicenter, noninferiority, randomized clinical trial took place in 7 ophthalmology centers in China. The trial started May 31, 2021, and 2-year follow-up ended May 31, 2024. Included in this analysis were patients with advanced PACG and cataract. Study data were analyzed from September 2024 to January 2025.InterventionsRandom assignment (1:1) to phacogoniotomy or phacotrabeculectomy.Main Outcomes and MeasuresThe primary outcome measure was reduction in IOP from baseline to the 2-year visit with a noninferiority margin of 4 mm Hg.ResultsA total of 124 participants (124 eyes) were randomized (mean [SD] age, 66.4 [8.6] years; 67 female [54.0%]), 65 (52.4%) to the phacogoniotomy group and 59 (47.6%) to the phacotrabeculectomy group. A total of 59 patients (90.7%) in the phacogoniotomy group and 52 patients (88.1%) in the phacotrabeculectomy group completed 2-year visits. All participants were Chinese. Mean (SD) IOP reduction was −25.6 (10.2) mm Hg and −24.7 (9.4) mm Hg in the phacogoniotomy and phacotrabeculectomy groups, respectively, and the upper boundary of the CI for difference in change between groups was lower than the 4-mm Hg noninferiority margin (mean difference, −0.5 mm Hg; 97.5% CI, −1.7 mm Hg to 0.8 mm Hg; P = .42). The mean difference for complete success for phacogoniotomy vs phacotrabeculectomy was −6.7% (95% CI, −21.4% to 8.8%; P = .47) and for qualified success was 1.4% (95% CI, −11.0% to 14.3%, P = .30). Median (IQR) number of antiglaucomatous medication was 0 (0) vs 0 (0; Hodges-Lehmann estimate of location shift, 0; 95% CI, 0; P =.12) with phacogoniotomy vs phacotrabeculectomy, respectively (mean difference, 0.13; 95% CI, −0.36 to 0.63; P = .60).Conclusions and RelevanceMean IOP reduction with phacogoniotomy was noninferior to phacotrabeculectomy for advanced PACG and cataract at 2-year follow-up with no differences detected in complete or qualified success or mean number of antiglaucomatous medications. These findings support phacogoniotomy as an alternative to phacotrabeculectomy for patients with advanced PACG and cataract.Trial registrationClinicalTrials.gov Identifier: NCT04878458

Abstract INTRODUCTION Biomarkers play a crucial role in understanding Alzheimer's disease (AD) pathogenesis and treatment effects. However, comparing biomarker measures without standardization and appreciating their magnitude relative to the disease can be challenging. METHODS To address this issue, we propose the CentiMarker approach, similar to Centiloid, which provides a standardized scale between normal (0) and nearly maximum abnormal AD (100) ranges. We applied this scale to cerebrospinal fluid (CSF) biomarkers in dominantly inherited AD and sporadic AD cohorts. RESULTS CentiMarkers facilitated the interpretation of disease abnormality, demonstrating comparable changes and distributions of AD biomarkers across disease stages. CentiMarkers make the treatment effect more comparable than their original scales across various biomarkers. DISCUSSION The versatility of CentiMarkers makes it a valuable tool for standardized biomarker comparison in AD research, enabling informed cross‐study comparisons and contributing to accelerated therapeutic development. Adoption of the CentiMarker scale could enhance biomarker reporting and advance our understanding of AD. Highlights Comparing fluid biomarkers without appreciating their magnitude relative to the disease can be challenging. We propose a CentiMarker metric to standardize biomarker measures from normal (0) and nearly maximum abnormal AD (100) ranges. CentiMarkers make the treatment effect more comparable across various biomarkers than when using the original scales.

AbstractObjectiveThis study aims to evaluate the impact of parity on the severity and recurrence rates of idiopathic subglottic stenosis (iSGS) in premenopausal females.Study DesignA retrospective cohort study.SettingTwo tertiary care centers from 2002 to 2024.MethodsWe analyzed premenopausal iSGS patients under 40 years who underwent balloon dilation or laser wedge excision. Clinical features, including demographics and pregnancy history, were examined. Recurrence rates between nulliparous and parous patients were compared using Poisson regression, adjusting for age and follow‐up duration. Linear regression assessed the relationship between pregnancy and iSGS recurrence.ResultsForty‐eight patients were included, with 36 parous and 12 nulliparous. Adjusting for age and follow‐up, the mean recurrence rate was 2.6 times higher in parous patients (95% confidence interval [CI]: [1.5, 4.8], P = .0008). Each additional pregnancy was associated with 0.81 additional recurrences (95% CI: [0.05, 1.57], P = .0375). No significant differences in surgery‐free time were observed between groups.ConclusionParity and pregnancy significantly increase the risk of iSGS recurrence, although they do not accelerate subsequent recurrences. Health care providers should counsel women of childbearing age about these risks in family planning discussions, emphasizing shared decision‐making regarding potential surgical interventions.Level of evidence3.

Abstract ZUMA-8 evaluated the safety of brexucabtagene autoleucel (brexu-cel), a CD19-directed autologous chimeric antigen receptor (CAR) T-cell immunotherapy, for patients with relapsed/refractory chronic lymphocytic leukemia (R/R CLL). Patients with ≥2 prior lines of therapy (including a Bruton tyrosine kinase inhibitor) underwent leukapheresis, optional bridging therapy, and conditioning chemotherapy (fludarabine/cyclophosphamide) before infusion of 1 × 106 (cohort 1) or 2 × 106 (cohort 2) anti-CD19 CAR T cells per kg. Patients in cohort 3 (low tumor burden), and cohort 4A (postibrutinib) received 1 × 106 cells per kg. Fifteen patients, median age of 63 years (range, 52-79), were treated in cohorts 1 (n = 6), 2 (n = 3), 3 (n = 3), and 4A (n = 3). Median follow-up was 24.3 months. One dose-limiting toxicity was observed in cohort 3 (grade 4 cytokine release syndrome). Grade ≥3 neurologic events occurred in 3 patients (20%). Seven of 15 patients responded (overall response rate, 47%; complete response [CR], 7%), including all 3 patients in cohort 3 (1 with CR). CAR T-cell expansion occurred in 4 patients (27%), with an apparent weak inverse correlation with absolute lymphocyte count before apheresis. Brexu-cel had no new safety signals in R/R CLL. CAR T-cell expansion and responses occurred in patients with low tumor burden. This trial was registered at www.clinicaltrials.gov as #NCT03624036.

AbstractA deeper understanding of pathophysiology, from the initiation of tumors of epithelial cells to the outcomes associated with it, is imperative to test potential interventions for these diseases. However, few models can accomplish this because of the complexity of origin cells and their transformation. We established an epithelial cell original tumor mouse model by conditional KrasG12D activation and tumor suppressor gene p53 deletion specifically in epithelial cells of the whole body using Cytokeratin 19 (CK19) promoter via Cre‐ERT mediation. Multiple tumors derived from epithelial cells developed in this novel model. This model can recapitulate the progress of intestinal, pancreatic, liver, lung, and subcutaneous tumors which derive from epithelial cells. This model is suitable for studying the pathophysiology of tumors derived from epithelial cells and may have the potential to test interventions.

Abstract Aims Functional tricuspid regurgitation (FTR) associated with degenerative mitral regurgitation (DMR) accentuates the severity of heart failure and is a marker of poor prognosis. Little is known about FTR associated with asymptomatic DMR. Methods and results The study included 1249 asymptomatic patients with moderate or severe DMR from the Mitral Regurgitation International Database-Quantitative (MIDA-Q) registry (mean age 64 ± 15 years, 25% female). Despite the asymptomatic status, absent/trivial FTR was noted in only 42%, mild in 34.5%, moderate in 11%, and severe FTR in 12.5%. Patients with higher FTR grades were older and more often female and had higher EuroScore II, larger left atrial volumes, and more atrial fibrillation (all P < 0.05). Patients with moderate or severe FTR had comparable 5-year survival (64 ± 4% and 65 ± 4%) and lower than patients with no/trivial FTR(96 ± 1%, P < 0.001). After adjustment for key prognostic factors, including age, left ventricular dilatation and dysfunction, DMR severity, left atrial dilatation, and pulmonary hypertension, ≥moderate FTR remained a strong predictor of mortality (HR = 2.08 [1.17–3.72], P = 0.013). Sensitivity analysis showed stable impact of ≥moderate FTR among patients with/without pulmonary hypertension, in women and men and for any other subset. For patients who underwent mitral valve surgery, post-operative survival rates were similar between those with no/trivial FTR and those with ≥moderate or severe FTR (P = 0.76), suggesting that surgery could reduce the excess mortality related to preoperative FTR. Conclusions Among asymptomatic patients with significant DMR, ≥moderate FTR is frequent and independently associated with higher mortality, independently of traditional guideline-based risk factors. These findings suggest that ≥moderate FTR should lead to consideration of early mitral surgery to improve outcomes.

Abstract Background Atypical teratoid rhabdoid tumor (ATRT) is a deadly central nervous system embryonal tumor caused by loss of SMARCB1, a core subunit of SWItch/Sucrose Non-Fermentable (SWI/SNF) chromatin remodeling complexes. SMARCB1-deficient cancers are defined by loss of cell differentiation-associated enhancers, but how SWI/SNF interacts with other arbiters of cell differentiation (specifically lineage-specific transcription factors [TFs]) remains poorly understood. Methods We leveraged a multi-omics approach, patient-derived ATRT cells, and patient-derived orthotopic xenografts to investigate the interplay of SWI/SNF with lineage-specific TFs in a clinically relevant setting. Results We observe that an activating protein 1 (AP-1)-dependent transcriptional regulatory network is lost in ATRT, and AP-1 and lineage-specific TFs TEAD1 and ZIC2 require SMARCB1 for enhancer binding. SMARCB1-dependent SWI/SNF integrates transcriptional functions of lineage-specific TFs into a core regulatory circuit that depends on the AP-1 subunit c-JUN, whose expression is determined by a SMARCB1-dependent super-enhancer that is lost in ATRT-MYC. In the absence of SMARCB1, lineage-specific TFs are sequestered to promoters, where they maintain core transcriptional programs necessary for cell survival. Targeting residual, promoter-proximal TF activity by a protein degrader of the SWI/SNF ATPase SMARCA4 or small-molecule inhibitors that indirectly inhibit AP-1 and TEAD activity abrogates expression of these networks, reducing cell viability in vitro and prolonging survival in an orthotopic patient-derived xenograft model. Conclusions These results demonstrate SWI/SNF complexes are critical for lineage-specific TF binding and activity at both promoters and enhancers. In the context of ATRT, these findings reveal a previously underappreciated therapeutic vulnerability in targeting residual promoter-proximal TF function in ATRT.

ABSTRACT Recent development of single-cell technology across multiple omics platforms has provided new ways to obtain holistic views of cells to study disease pathobiology. Alzheimer’s disease (AD) is the most common form of dementia worldwide, yet the detailed understanding of its cellular and molecular mechanisms remains limited. In this study, we analyzed paired single-cell transcriptomic (scRNA-seq) and chromatin accessibility (scATAC-seq) data from the Seattle Alzheimer’s Disease Brain Cell Atlas (SEA-AD) Consortium to investigate the molecular mechanisms of AD at a cell-subpopulation-specific resolution focusing on glial cells. We benchmarked various multi-omics integration methods using diverse metrics and built an analytic workflow that enabled effective batch correction and cross-modality alignment, creating a unified cell state space. Through integrative analysis of 26 human brain samples, we uncovered AD-associated gene expression and pathway changes in glial subpopulations and highlighted important transcriptomic and epigenomic signatures via functional inference and interpretable machine learning paradigms, discovering the profound involvement of the Solute Carrier proteins (SLC) family genes in multiple glial cell types. We also identified glial cell-specific regulatory programs mediated by key transcription factors such as JUN and FOSL2 in astrocytes, the Zinc Finger (ZNF) family genes in microglia, and the SOX family of transcription factors in oligodendrocytes. Our study provides a comprehensive workflow and a high-resolution view of how glial regulatory programs are disrupted in AD. Our findings offer novel insights into disease-related changes in gene regulation and suggest potential targets for further research and therapy.

Abstract Purpose: Digital proteomic profiling was performed to identify spatial context in relationship to patient response and survival after anti–PD-1 therapy in metastatic colorectal cancer. Experimental Design: Primary colorectal cancers with deficient mismatch repair from patients treated with anti–PD-1 antibodies were analyzed (N = 30) using digital spatial profiling (GeoMx nCounter). At the invasive margin, 71 proteins were profiled in 10 regions of interest/slide that were segmented into 3 compartments labeled with pan-cytokeratin (epithelia), CD45 (stromal cells), and SYTO13 (nuclei). In an independent cohort (n = 13), digital spatial profiling data and single-cell transcriptomic data were analyzed. Differential protein abundance, after Benjamini–Hochberg correction, was examined by clinical response and progression-free survival (PFS) using multivariable Cox regression. Results: Protein abundance varied significantly between epithelial and stromal compartments. Nonresponders to anti–PD-1 showed higher fibronectin and smooth muscle actin abundance in the epithelial compartment that was associated with significantly shorter PFS (adjusted HR: 6.49 and 4.52, respectively; P < 0.05). In CD45+ stroma, increased expression of proteins related to T cells (CD3 and CD4), NK cells (CD56), antigen presentation (CD40), immune activation (CD27, ICOS), and apoptosis (GZMA) were found in responders (vs nonresponders) to anti–PD-1; each marker was significantly associated with longer patient PFS (0.02 < adjusted HR < 0.17; P < 0.05). In a separate cohort, consistent results by compartment were found for fibronectin and CD56. Gene expression data revealed that fibronectin and smooth muscle actin were primarily derived from cancer-associated fibroblasts. Conclusions: Spatially resolved protein profiles within microenvironments of deficient mismatch repair colorectal cancers can influence patient response and survival after anti–PD-1, highlighting their potential clinical significance.
