Abstract This real-world retrospective cohort study evaluated utilization and comparative effectiveness of covalent Bruton tyrosine kinase inhibitor (cBTKi) monotherapies in relapsed/refractory mantle cell lymphoma (R/R MCL) from electronic health records in the United States. Adults with R/R MCL who received second- or third-line (2L/3L) zanubrutinib, acalabrutinib, or ibrutinib monotherapy, on or after 1 January 2018, were included. Inverse probability of treatment weighting was used in adjusted Cox models to compare real-world time-to-next treatment (rwTTNT) and overall survival (rwOS). Among 698 patients who received 2L/3L cBTKi monotherapy, 49%, 32%, and 19% received acalabrutinib, ibrutinib, and zanubrutinib, respectively. Unadjusted analyses showed median rwTTNT for 2L zanubrutinib, acalabrutinib, and ibrutinib was 14.5 (95% confidence interval [CI], 11.0-23.2), 12.8 (95% CI, 10.5-15.6), and 10.3 (95% CI, 7.6-13.7) months, and median rwOS was 26.4 (95% CI, 23.2 to not reached [NR]), 29.2 (95% CI, 22.9-38.1), and 29.3 (95% CI, 21.8-41.6) months, respectively. Median rwTTNT for 3L zanubrutinib, acalabrutinib, and ibrutinib was 21.1 (95% CI, 3.9 to NR), 9.2 (95% CI, 6.8-14.7), and 9.6 (95% CI, 4.8-18.0) months, and median rwOS was NR (95% CI, 27.3 to NR), 27.4 (95% CI, 15.1-42.2), and 27.0 (95% CI, 15.6 to NR) months, respectively. Adjusted models in the 2L/3L cohorts combined showed numerically longer rwTTNT and statistically significantly longer rwOS for zanubrutinib vs ibrutinib (hazard ratio, 0.63; 95% CI, 0.42-0.96), and trends for improved rwTTNT and rwOS for zanubrutinib over acalabrutinib. Toxicity was a frequent reason for changing to another cBTKi. These findings suggest potential improvements in rwTTNT and rwOS with the use of second- and next-generation cBTKis for R/R MCL from 2018 and beyond.

Abstract BACKGROUND The phase III ECOG-ACRIN E3F05 trial tested whether combined therapy with radiation and concomitant followed by adjuvant temozolomide is more effective than radiation alone in patients with grade II gliomas. The study incorporated 1p/19q analysis but predated assessment of IDH mutational status. We previously reported that the addition of temozolomide to radiotherapy significantly improved overall survival in grade II gliomas, with similar hazard ratios in co-deleted (0.56) and non-codeleted (0.53) tumors. Herein we incorporate the results of DNA methylation profiling to examine outcomes in IDHmt, non-codeleted subjects as well as co-deleted ones. METHODS All 172 subjects underwent 1p/19q co-deletion analysis as a stratification factor, 1p and 19q deletion analysis was performed on formalin-fixed paraffin-embedded (FFPE) gliomas by Fluorescent In Situ Hybridization (FISH) following standard methods, 97/172 (56.3%) had tissue with 60% or more tumor content available for DNA methylation profiling using Heidelberg classifier v12 and Bethesda Classifier 2.0 to ascertain classification as IDH mutant glioma and alternative evaluation of 1p/19q co-deletion status. RESULTS Of the 172 subjects, 74 (43.0%) had 1p/19q codeletion by FISH, 38 (22.1%) were IDHmt without codeletion, 14 (8.1%) were IDHwt, and 46 (26.7%) were non-codeleted with unknown IDH status (these include n=4 pts originally classified as 1p/19q undetermined). With a median follow-up of 130 months, the addition of TMZ to RT improved OS in patients with IDHmt, non-codeleted tumors (HR 0.15 (0.03-0.74)) and 10-year OS from 39% to 80%. In codeleted tumors, the addition of TMZ improved OS (HR 0.51 (0.19-1.42)) and 10-year OS from 68% to 90%. CONCLUSION The addition of temozolomide to radiation improves overall survival in both co-deleted and IDHmt, non-co-deleted grade II gliomas.

Importance Transthyretin amyloid cardiomyopathy (ATTR-CM) is underdiagnosed despite expanding treatment options. Objective To develop and evaluate an artificial intelligence (AI)–augmented clinical program for ATTR-CM detection. Design, Setting, and Participants This nonrandomized clinical trial involved constructing an AI model, ATTRACTnet, using electrocardiogram waveforms, echocardiographic measurements, demographics, and diagnosis codes for orthopedic manifestations of amyloidosis. A single-system, multisite, single-arm, open-label trial was conducted to evaluate its real-world performance. The model was trained and validated at a large academic referral site for ATTR-CM with external validation at an academic site. The trial was conducted as a single-system, multisite trial. Patients with left ventricular (LV) wall thickness 12 mm or more and an ATTRACTnet score 0.5 or higher were eligible. Exclusions included prior ATTR-CM testing, hypertrophic cardiomyopathy, expected life span less than 1 year, nursing home residence, advanced dementia, or LV wall thickness less than 14 mm explained by uncontrolled hypertension or moderate/severe aortic stenosis. Intervention Eligible patients were notified and offered nuclear scintigraphy testing, monoclonal protein testing, and follow-up care on agreement from the treating physician. Main Outcomes and Measure The primary outcome was a diagnosis of ATTR-CM by consensus criteria. ATTR-CM testing positivity was compared with historical and contemporary controls. Results ATTRACTnet was developed in an internal test set of 799 patients (mean [SD] age, 75.1 [11.1] years; 516 [64.7%] male and 283 [35.3%] female) using 5-fold cross-validation with an additional external test set of 422 patients. It had good discrimination for ATTR-CM detection with an area under the receiver operator characteristic curve of 0.85 (5-fold cross-validation, 0.77-0.85) in the internal set and 0.82 (95% CI, .81-0.83) in the external test set with similar performance in Hispanic, non-Hispanic Black, and non-Hispanic White patients. A total of 1471 patients were identified with positive AI model scores 0.5 or more during the study period, with 256 eligible patients who met study criteria. Of these patients, 50 underwent amyloidosis testing after physician and patient approval; 24 (48%) were diagnosed with ATTR-CM, and 21 (88%) initiated treatment within 3 months. The positivity rate was more than 2.8 times higher than historical controls (15.3%; 95% CI, 13.1%-17.9%; P < .001), with an 18% relative increase in new diagnoses vs the prior year. Conclusions and Relevance AI-augmented screening may improve ATTR-CM detection and identify patients who are missed by usual care. Prospective randomized trials are needed to determine if outcomes are improved. Trial Registration ClinicalTrials.gov Identifier: NCT06469372

Importance Adjuvant radiotherapy can improve locoregional control and survival in patients with olfactory neuroblastoma (ONB), particularly with advanced-stage and histologic-grade disease. Standard radiotherapy treatment is with intensity-modulated radiotherapy (IMRT). Proton beam radiotherapy (PBRT) provides theoretical advantages in greater sparing of dose to uninvolved organs at risk. Objective To investigate if there are differences in the effectiveness and radiation treatment–related adverse events (RTAEs) between adjuvant IMRT and PBRT for patients with ONB. Design, Setting, and Participants This propensity score–matched cohort study included patients with ONB treated between February 2005 and April 2021 with either IMRT or PBRT at 9 academic tertiary care centers in North America. Patients were matched 1:2 based on age, modified Kadish stage, and Hyams grade. Data were analyzed from July 2024 to January 2025. Exposure Adjuvant IMRT or adjuvant PBRT. Main Outcomes and Measures Local recurrence-free survival (RFS), any RFS, and overall survival (OS). RTAEs, ie, grade 2 events or higher based on Common Terminology Criteria for Adverse Events, were recorded for both modalities. Results Of 54 included patients, 27 (50%) were female, and the mean (SD) age was 46.2 (15.4) years. A total of 18 were treated with PBRT and 36 were treated with IMRT. Most patients had modified Kadish stage C disease (33 of 54 [61%]), and 24 patients (44%) had Hyams grade III or IV disease. The RTAE rate was 20% (8 of 40); IMRT had a rate of 21% (6 of 29), and PBRT had a rate of 18% (2 of 11). The difference in the point estimates for 10-year RFS showed a potential clinical benefit favoring IMRT, although the wide confidence interval indicates uncertainty (10-year RFS: IMRT, 63.3%; 95% CI, 44.6-89.8; PBRT, 37.8%; 95% CI, 14.2-100; difference, 25.5 percentage points; 95% CI, −17.6 to 68.6). There were no clinically meaningful differences in 10-year local RFS (IMRT, 75.6%; 95% CI, 59.8-95.4; PBRT, 72.7%; 95% CI, 45.2-100; difference, 2.9 percentage points; 95% CI, −35.9 to 41.7) or 10-year OS (IMRT, 61.8%; 95% CI, 42.8-89.1; PBRT, 57.1%; 95% CI, 24.3-100; difference, 4.7 percentage points; 95% CI, −49.2 to 58.6), although wide confidence intervals indicate considerable uncertainty. Conclusions and Relevance Due to the imprecision of estimates, no definitive conclusions can be made regarding the comparative effectiveness of IMRT vs PBRT for patients with ONB. These preliminary data may inform the design of appropriately powered prospective studies evaluating the efficacy of PBRT vs IMRT in this population.

Abstract Background and Aims PKD1 and PKD2 are the two major genes in autosomal dominant polycystic kidney disease (ADPKD). Up to 15% of patients with ADPKD-like phenotype are genetically unresolved (GUR) or carry variants in minor cystogenes including IFT140. Here, we describe features of an ADPKD-like phenotype linked to monoallelic predicted loss-of-function (pLoF) variants in a new candidate cystogene, IFT172. The IFT172 protein is part of the IFT-B subcomplex and plays a role in protein trafficking within primary cilia. Biallelic variants in IFT172 cause a severe ciliopathy. Method A total of ∼3200 unrelated individuals with cystic kidney disease (CyKD) underwent genetic testing employing whole-exome sequencing (WES) or massive-parallel-sequencing (MPS) gene panels in Brest, Lyon and in Rochester, MN. In addition, 185 individuals ICD coded as CyKD from Mayo Clinic Biobank (MCBB) underwent WES. Clinical and genetic data of individuals with predicted loss-of-function variants of IFT172 were collected and analyzed. Also, the Genomics England 100kG Project cohort was screened for pLoF variants in IFT172. Results In the CyKD population, 18 patients with a monoallelic pLoF variant in IFT172 were identified. In the MCBB CyKD cohort, 3 individuals had IFT172 pLoF variants. We describe the clinical presentation of these 21 affected individuals (15 males). Median age at CyKD diagnosis was 67 (range 34–88) years. Family history for CyKD was positive in 10 (48%), negative in 9 (42%) and not known in 2 (10%) individuals. Arterial hypertension was present in 9 (45%) patients, in three of them diagnosed before age of 50 years and in 6 at a later age. Hypertension status was not known in 10 of them. A majority of the patients presented with multiple bilateral cortical kidney cysts with moderate kidney enlargement or normal-sized kidneys with large, exophytic kidney cysts and were classified as Mayo Imaging Class 2A. In one patient, unilateral CyKD was present with >10 cysts. Liver cysts were present in 4 (19%) and gout in three (15%) patients. None of the three patients who underwent screening were found to have intracranial aneurysm. Median eGFR at diagnosis (N = 19) was 53 (range 29–119) ml/min/1.73 m2. Of 15 patients older than 60 y, one had CKD stage G1, 5 stage G2, 3 stage G3a, 5 stage G3b and one G4. Only one patient of African descent (APOL1 G1/G0) reached kidney failure at age of 43 y, likely due to additional contribution of uncontrolled hypertension and poorly controlled diabetes. In addition, in two patients, the IFT172 pLoF variant was identified alongside a pathogenic variant in PKD1 (p.Gln2519*) or PKD2 (c.844-1G>T). Both progressed to kidney failure at an earlier age than typically observed with PKD1 or PKD2 alone, at 29 and 52 years, respectively. Familial segregation is ongoing. Of the total of 94,799 patients recruited in “rare disease program” within 100kG Project, 51 carried monoallelic pLoF variants in IFT172 (genetic prevalence: 5.38 [0.95 CI 3.9–6.86] per 10,000). Four of them (7.8%) had CyKD. Conclusion Carriers of monoallelic pLoF variants in IFT172 are likely to develop cystic kidney disease (CyKD) that is atypical of classical ADPKD, generally associated with a favorable kidney prognosis. Nonetheless, individuals over the age of 60 may have an increased risk of progressing to CKD stage G3 or worse. Disease penetrance in IFT172 pLoF variant carriers appears to be incomplete, similar to what is observed in IFT140.

Abstract Aims Endogenous endophthalmitis (EE) is a rarely reported complication of infective endocarditis (IE). In an international series, we sought to determine the clinical and microbiological profile, treatment, and outcome of patients presenting with IE-related EE. Methods and results Cases recorded from 2014 to 2023 in nine centres in Europe and the United States were collected. Results were compared to a matched control group. Conclusion Sixty-six patients with EE were reported, mean age of 65.2 ± 14.9 years, 71% (n = 47) male. Blood cultures were positive in 97% (64 cases) of patients, with a predominance of streptococci (46%, n = 30). As compared with the control group (n = 264), the EE group presented with more frequent diabetes (35% vs. 21%, P = 0.02), history of cirrhosis (9% vs. 3%, P = 0.04), glomerulonephritis (15% vs. 0.4%, P < 0.001), embolism before admission (92% vs. 55%, P < 0.001), and Janeway lesions (9% vs. 1%, P = 0.002). Streptococcal infection (46% vs. 26%, P = 0.001) was more frequent and Enterococcal infection (0% vs. 18%, P < 0.001) less frequent in the EE group. The main ocular symptoms were a decrease in visual acuity (96%), red eye (55%), and ocular pain (55%). Treatment of EE consisted of intravitreal antibiotic injection in 55 (83%) patients and vitrectomy in 17 (26%). Improvement of visual acuity was observed in 36 (55%) patients. Conclusion EE is a serious complication of IE with severe residual vision impairment. Patients with IE should be evaluated for ocular complications, since early detection of EE is crucial to prevent delays in management and to preserve visual function.

The clinical courses of 51 patients with postherpetic pain who were referred to the Pain Clinic were reviewed. Twenty-three patients were treated on a trial basis with an intensive series of sensory and sympathetic blocks, whereas 28 control patients, who were seen before the initiation of this study, were treated with other modalities. Fifteen control patients (54%) were disabled by postherpetic neuralgia, as compared with four patients (17%) in the trial group.
