Abstract Background Older adults remain underrepresented in prospective trials of immunotherapy for advanced lung cancer. To estimate pembrolizumab adverse events, we conducted a multicenter, nonrandomized, open-label phase 2 trial of oncologist-choice first-line pembrolizumab with or without chemotherapy for older adults with advanced lung adenocarcinoma. Methods Alliance for Clinical Trials in Oncology A171901 enrolled patients aged 70 years and older with stage IV or recurrent lung adenocarcinoma starting oncologist’s choice of first-line pembrolizumab with or without carboplatin and pemetrexed. The primary endpoint was the proportion of patients experiencing a solicited grade 3 or greater adverse event within 6 months. Secondary endpoints included overall survival, quality of life, and association of a geriatric assessment toxicity risk score with severe adverse events. Results Among 95 evaluable patients, 43 (45.3%) received pembrolizumab and 52 (54.7%) received pembrolizumab plus chemotherapy. Median age was 77 years (range = 70-92 years); 11.6% had an E Performance Status of 2 or higher. During 6 months of treatment, 25.6% (95% CI = 13.5% to 41.2%) experienced a solicited grade 3 or greater adverse event in the monotherapy group and 42.3% (95% CI = 28.7% to 56.8%) in the combination group. Median overall survival was 16.4 months (95% CI = 10.1 to not estimable) with monotherapy and 29.9 months (95% CI = 16.4 to not estimable) with combination therapy. Quality of life worsened during treatment. The geriatric assessment toxicity risk score was not associated with severe adverse events with pembrolizumab with or without chemotherapy. Conclusions Older adults with advanced lung adenocarcinoma receiving pembrolizumab with or without chemotherapy had comparable adverse event rates to those in prior registration trials that excluded medically frail patients. These findings can inform shared decision making and support inclusion of older adults in future trials. Clinical Trial NCT04533451 (https://clinicaltrials.gov/study/NCT04533451)

Abstract INTRODUCTION Remote neuropsychological testing can monitor brain health in individuals with or at risk of Alzheimer's disease (AD). We evaluated acceptability and validity of the Cogstate Brief Battery (CBB) for remote administration. METHODS Non‐demented adults from the Alzheimer's Disease Neuroimaging Initiative (ADNI) completed the CBB in‐clinic under supervision, then remotely every six months, with annual in‐clinic reassessments. Groups included cognitively unimpaired (CU) adults with normal amyloid (CU Aβ−) or elevated amyloid (CU Aβ+), and individuals with mild cognitive impairment with or without amyloid (MCI Aβ+, MCI Aβ−). Performance was compared across contexts and longitudinal changes were examined. RESULTS At baseline, MCI Aβ+ participants performed worse than CU Aβ−. CBB performance was similar across contexts, with consistent group differences. Over time, MCI Aβ+ participants showed greater decline on remote CBB measures than CU Aβ− adults. DISCUSSION Remote unsupervised CBB assessments are valid, reliable, and sensitive to AD‐related cognitive impairment.

Inverted sinonasal papilloma (ISP) and respiratory epithelial adenomatoid hamartoma (REAH) are sinonasal lesions with overlapping clinical, radiographic, and histologic features, making accurate diagnosis challenging. ISP is a benign but aggressive tumor with a propensity for local destruction, recurrence, and malignant transformation, whereas REAH is a hamartomatous lesion often arising in the olfactory cleft. We present four patients with lesions initially suspected to be ISP based on intraoperative frozen section but ultimately diagnosed as REAH on permanent pathology. All patients had polypoid sinonasal masses, frequently involving or adjacent to the olfactory cleft. Intraoperative frozen sections were often inconclusive or favored ISP, reflecting the difficulty of distinguishing these entities. Histologic analysis revealed that epithelial thickness served as a key morphologic feature differentiating ISP from REAH, with REAH exhibiting ciliated glandular proliferation and ISP characterized by hyperplastic epithelium with features of columnar and squamous differentiation. These patients underscore the diagnostic pitfalls of small biopsies and frozen sections, and highlight the importance of permanent specimens and collaboration with experienced pathologists. Accurate differentiation is critical, as management strategies differ substantially: ISP requires aggressive resection and long-term surveillance, while REAH may be treated with limited excision and minimal follow-up.

Background: Although donor and recipient characteristics are used to estimate graft failure risk, they remain limited in predicting early acute rejection. We developed and validated a next-generation sequencing (NGS) assay targeting the pre-transplant immunologic profile to predict early acute rejection following kidney transplantation. Methods: This prospective, international study enrolled 321 kidney transplant participants across 13 sites, forming discovery and validation cohorts. Peripheral blood was collected prior to transplant and at 1, 3, 6, 12, and 24 months post-transplant, with protocol biopsies performed at 3 and 12 months, as well as any indication biopsies. Biopsies were assessed by a blinded central pathologist according to the 2019 Banff criteria. The pre-transplant risk assessment (PTRA™) test to evaluate RNA expression of a 29-gene signature algorithm designed to predict early acute rejection risk was clinically validated utilizing 122 deceased donor kidney transplant recipients. Results: PTRA classified 31 of 122 participants (25%) as high-risk and 91 (75%) as low-risk. There were 9 early acute rejection events in the first 60 days post-transplant: 6/31 (19%) in the high-risk group and 3/91 (3%) in the low-risk group. PTRA discrimination for early acute rejection at 60 days post-transplant yielded an AUC of 0.78 (95% confidence interval [CI]: 64.4 to 91.5), p<0.001. A cut-off of ≤45 was defined as low-risk and >45 as high-risk for early acute rejection within 60 days post-transplant. Sensitivity 0.67 (95% CI: 0.36 to 0.97), specificity 0.78 (95% CI: 0.70 to 0.86), positive predictive value 0.19 (95% CI: 0.05 to 0.33), and negative predictive value 0.97 (95% CI: 0.93 to 1.00). The odds ratio comparing patients identified as high- vs low-risk by PTRA was 7.04 (95% CI: 1.64 to 30.2), p=0.009. Conclusions: This study validates the ability of PTRA to stratify kidney transplant recipients as high- or low-risk for early acute rejection using a pre-transplant transcriptomic profile, with implications for graft health and personalized treatment management.

Abstract Aims Trends in upright seated pulmonary artery pressure (PAP) with synchronous measurement of weight, blood pressure (BP), and heart rate (HR) have not been compared prior to heart failure events (HFE) and other causes of hospitalization during remote monitoring. Methods We analysed 24-month data from patients in the PROACTIVE-HF trial. Participants (N = 456) used the CordellaTM HF daily to measure seated PAP, weight, BP, and HR, all taken and transmitted within minutes. Events that were analysed included HFE, those potentially related to HF treatment (HF-TRE), and others (non-HFE). Parameters were trended from 60-days before (D-60) to 30-days after (D + 30) the day of the event (D = 0), and their concurrent changes were compared between D-60 and D = 0, and D = 0 and D + 30 using a mixed effects model. Results There were 196 HFE, 276 non-HFE, and 66 HF-TRE. Prior to HFE, average mean PAP (mPAP) increased from 27.8 ± 10.9 mmHg at D-60 to 32.6 ± 11.2 mmHg at D = 0 (P &lt; .001), and decreased to 30.0 ± 12.4 mmHg at D + 30 (P = .001). Kinetics of mPAP before HFE differed by left ventricular ejection fraction (LVEF); mPAP rose by 3.4 ± 6.8 mmHg in 2 weeks before HFE in those with LVEF &gt;40%, whereas a similar magnitude (3.1 ± 9.1 mmHg) of mPAP rise occurred over 6-weeks before HFE in those with LVEF ≤40%. No consistent changes in weight, SBP, or HR prior to HFE were observed (P &gt; .05). Changes in vital signs but not mPAP were noted prior to HF-TRE and non-HFE. Conclusion Seated mPAP increased weeks in advance of HFE and vital signs did not change consistently before HFE. Differential kinetics of mPAP prior to HFE by the LVEF suggest that an uptrend in seated mPAP may need to be addressed more rapidly in those with LVEF&gt;40%. Changes in vital signs with non-HFE and HF-TRE need further validation.

Abstract Background Meningiomas exhibit clinical heterogeneity. Radiotherapy (RT) remains the only adjuvant therapy, but tumor-control is variable, and biomarkers are limited. NRG/RTOG-0539 is the first prospective phase 2 trial to stratify meningioma patients for adjuvant RT based on clinical risk. Here, we apply modern molecular tools to this cohort and identify correlates of RT response. Methods Tumor tissue from 100 RTOG-0539 patients was profiled using DNA methylation arrays, RNA sequencing, and whole-exome sequencing. Recurrence scores, Molecular Groups, gene expression, and copy number alterations were compared across clinical groups and between RT responders and non-responders; non-response was defined as progression or death within 3 years. Results Modern grading criteria, including brain invasion, TERT mutation, CDKN2A/B deletion, and 1p/1q status, would reclassify 10% of tumors and alter treatment group assignment in 7%. Non-responders to RT exhibited more frequent 1p and 14q loss, and more copy number alterations. Transcriptomic and epigenetic profiling revealed immune-related signatures in responders and cell cycle–related pathways in non-responders, several of which overlapped with targets of vorinostat, a histone deacetylase inhibitor previously validated in aggressive meningioma models. The Proliferative Molecular Group was an independent predictor of post-RT recurrence in multivariable analysis, outperforming WHO grade. Conclusion Multi-omic analysis of the NRG/RTOG-0539 cohort shows that updated WHO grading criteria, incorporating molecular and cytogenetic features, improve risk stratification. However, molecular classification, particularly the Proliferative group, remains an independent and stronger predictor of RT response. These findings support integrating molecular biomarkers alongside modern grading frameworks to guide treatment and trial design in meningioma. Clinical Trial Information NCT00895622.

The NCCN Guidelines for Prostate Cancer include recommendations for staging and risk assessment after a prostate cancer diagnosis and for the care of patients with localized, regional, recurrent, and metastatic disease. These NCCN Guidelines Insights summarize the panel’s discussions on select 2026 updates to the guidelines regarding nonmetastatic disease: the elimination of the very-low-risk group, updates to the Principles of Active Surveillance, and caution in the use of focal therapy in newly diagnosed patients.

Abstract Background T cell activation and polarization drive atherosclerosis. Among the mediators underlying T cell polarization, the epigenetic enzyme EZH2 catalyses the repressive mark H3K27me3. In humans, EZH2 is upregulated in T cells in advanced atherosclerosis, whereas its deficiency in T cells in mice limits plaque formation via an anti-inflammatory response. Emerging evidence indicates that EZH2 can also regulate lncRNAs and miRNAs by depositing H3K27me3 at their loci, repressing transcription. Purpose We hypothesize that EZH2 governs lncRNAs and miRNAs expression in T cells in the context of atherogenesis. Methods CD4+ T cells were isolated from spleens of atherosclerosis-prone T cell-specific Ezh2 (Ezh2cd4)-KO mice and WT littermates. Small RNA-seq (SMARTer® smRNA-Seq) and transcriptomic profiling (Prime-seq) were performed. Differential expression was assessed using edgeR. Selected miRNAs were validated by RT-qPCR. Putative miRNA targets were retrieved from miRTarBase (v. 8) and TargetScan, and gene ontology enrichment was performed using Metascape. Results In CD4+ T cells from Ezh2cd4-KO mice, 41 out of 2,950 mature miRNAs were differentially expressed (log2FC &gt; |0.8|, FDR &lt; 0.05), with 27 upregulated and 14 downregulated. Top upregulated miRNAs included miR-125a-5p, miR-130a-3p, miR-744-5p, miR-181a-5p, miR-181b-5p, miR-374b-5p, miR-99b, miR-3085, and miR-7049-3p. RT-qPCR confirmed that expression of miR-125a-5p, miR-181a-5p, miR-181b-5p, and miR-99b-5p were upregulated in Ezh2-deficient murine CD4+ T cells. GO enrichment analysis of downregulated genes revealed enrichment of IL-4, IL-9, IL-10, and TGF-β pathways, suggesting their relevance in T-cell function and differentiation. In human Jurkat T cells, pharmacological EZH2 inhibition using GSK126 or tazemetostat resulted only in the upregulation of miR-125a-5p and miR-99b-5p, confirming the conservation of the mechanisms in humans. Integration of our Prime-seq transcriptomics and smallRNAseq datasets with human and mouse predicted and experimentally validated targets of miR-125a-5p and miR-99b-5p identified six conserved target genes: STAT1, FAM169B, NDRG3, PSMB9, TRIB1, and RAB3IP. Conclusions Our findings indicate that Ezh2 represses miRNA expression in T cells during atherogenesis, thereby possibly promoting differentiation toward pro-atherogenic subsets while restraining anti-atherogenic transcriptional programs. Further research is needed to elucidate the underlying mechanisms. Ezh2-regulated miRNAs may represent promising targets to direct T cell plasticity to combat atherosclerosis.

Introduction Female distance runners are at elevated risk for impaired bone remodeling due to high mechanical loading, potential low energy availability, and sustained inflammatory stress. Collagen peptide (CP) supplementation has been proposed as a nutritional strategy to support type I collagen synthesis and modulate osteoimmune signaling; however, evidence in premenopausal endurance athletes is limited. This pilot randomized, double-blind, placebo-controlled trial examined the effects of four weeks of high-dose CP supplementation on markers of bone metabolism and inflammatory activity in endurance-trained premenopausal women. Methods Twenty-two participants (18–35 years; ≥35 miles/week [&gt;56km/week]) were randomized to CP (INT; 20 g/day) or isocaloric maltodextrin (CON). Pre- and post-intervention assessments, conducted in the early follicular phase, included serum procollagen type I N-terminal propeptide (P1NP), plasma C-terminal telopeptide of type I collagen (CTX-1), serum soluble receptor activator of nuclear factor-κB ligand (sRANKL), osteoprotegerin (OPG), the sRANKL/OPG ratio, and interleukin-6 (IL-6). Repeated-measures ANCOVAs were performed, adjusting for accumulated running distance and vitamin D status. Results A significant group × time interaction was observed for P1NP ( p = 0.04), with increases in INT and no change in CON. No significant interaction was observed for CTX-1 ( p = 0.13). Significant interactions were also observed for sRANKL ( p = 0.046) and IL-6 ( p = 0.03). No significant interaction effects were detected for sRANKL, OPG, or the sRANKL/OPG ratio. Discussion Short-term CP supplementation increased a marker of bone formation, altered osteoclast-related signaling, and reduced IL-6 in endurance-trained premenopausal women. These findings support the potential for CP-mediated modulation of bone turnover and inflammatory activity and warrant further investigation in larger, adequately powered trials incorporating structural bone outcomes.
