Abstract RATIONALE: Chronic lower respiratory diseases (CLRD) confer higher risks from respiratory viral infections, hence CLRD patients are prioritized for influenza, pneumococcal, and COVID-19 vaccination. Nonetheless, vaccine deferral and declination remain common. Given that COVID-19 vaccination is particularly polarizing, and attitudes toward it may differ from other vaccines, we assessed COVID-19 vaccination behaviors and attitudes in adults with versus without CLRD and/or smoking history, which is strongly associated with CLRD risk. METHODS: We pooled data from 10 cohorts participating in the Collaborative Cohort of Cohorts for COVID-19 Research (C4R) that collected pre-pandemic data on self-reported physician diagnosis of asthma or COPD. C4R assessed COVID-19 vaccination status through three waves of standardized questionnaires (2020-2022, 2021-2023, 2023-2024). Prompt COVID-19 vaccination was defined as self-report of receiving at least one COVID-19 vaccine by May 1, 2021. Cumulative COVID-19 vaccine count was self-reported on the Wave 3 Questionnaire. Vaccine attitudes and receipt of influenza and/or pneumococcal vaccines were self-reported on the Wave 1 or 2 Questionnaire. Age-adjusted Poisson regression was used to test associations of vaccination behaviors with CLRD and smoking status at the most recent pre-pandemic exam. RESULTS: Of 20,034 participants (pre-pandemic COPD, 9.3%; asthma, 11.7%; current smoking, 13.4%; former smoking, 36.3%), 64.2% reported prompt COVID-19 vaccination. Among the subset of 10,626 participants completing the Wave 3 Questionnaire in 2023-24, the median COVID-19 vaccine count was 3 (Q1:2, Q3:4). Compared to participants without CLRD, prompt vaccination was more likely in those with asthma (RR=1.04, 95%CI:1.01-1.07, p=0.008) and less likely with COPD (RR=0.94, 95%CI:0.91-0.98, p=0.001), but there were no differences in doses for asthma and COPD. Compared to never smokers, former smoking participants were more likely to receive prompt vaccination (RR=1.11, 95%CI:1.08-1.13, p<0.0001) and more vaccine doses (RR=1.03, 95%CI:1.01-1.05, p=0.015); conversely, current smoking was inversely associated with prompt vaccination (RR=0.94, 95%CI:0.91-0.97, p=0.001) and was associated with fewer doses (RR=0.93, 95%CI:0.89-0.96, p<0.0001). Participants with CLRD versus without CLRD were more likely to report receiving influenza and pneumococcal vaccines, but they were more likely to believe that vaccines are unsafe or ineffective (figure). CONCLUSIONS: COPD was associated with lower likelihood of prompt COVID-19 vaccination. Current smoking was associated with both lower likelihood of prompt COVID-19 vaccination and a lower number of COVID-19 vaccine doses by 2023-24. These associations may be partly attributed to negative vaccine attitudes and beliefs. How the COVID-19 pandemic may have influenced vaccine behaviors and attitudes merits additional study.

Abstract RATIONALE: Deferral and declination of the COVID-19 vaccine is correlated with many factors, including different health guidelines and difficulties accessing the vaccine. In the US, COVID-19 vaccines were made available in tranches of clinical risk starting in December 2020 and were available to all adults on April 19, 2021. In the post-pandemic period, repeating COVID-19 vaccination with updated formulations is broadly recommended. Given that the public health impact of vaccine allocation strategies depends on public acceptance of vaccination, we aimed to evaluate demographic, clinical and social correlates of (1) receiving at least one COVID-19 vaccine by May 1, 2021 (prompt vaccination) and (2) the total number of vaccine doses received (vaccine count) through 2023-2024. METHODS: The Collaborative Cohort of Cohorts for COVID-19 Research (C4R) is a prospective observational meta-cohort study comprising 14 extant NIH-funded population-based cohorts. C4R assessed COVID-19 vaccination using three waves of standardized questionnaires (2020-2021, 2021-2023, 2023-2024). Prompt vaccination was defined by participant self-report of vaccination before May 1, 2021; participants vaccinated after May1, 2021 were classified as non-prompt; participants with missing vaccination information were excluded. Vaccine count was defined by self-report on the 2023-2024 wave Questionnaire. Demographic, clinical and social factors were classified by self-report and/or objective measures from the most recent pre-pandemic cohort exam. Poisson models regressed either prompt vaccination or vaccine count on pre-pandemic factors. RESULTS: Of 17,866 participants (mean age, 6713 years; 60.1% female; 42.1% non-Hispanic White, 22.0% Black, 28.9% Hispanic/Latino, 3.4% American Indian, 2.3% South Asian, 1.4% East Asian), 11,481 (64.3%) reported prompt vaccination. Of the subset of 14,529 participants completing the Wave 3 questionnaire, the median vaccine count in 2023-24 was 3 (Q1, 2; Q3 4). Likelihood of prompt vaccination was higher with greater age, income, and education and with history of diabetes and hypertension; prompt vaccination was less likely with male sex, current smoking, and non-White race and ethnicity (table). Similar associations were observed with respect to vaccine count (table). CONCLUSIONS: In a diverse C4R cohort community-based sample, earlier and greater COVID-19 vaccination was associated with older age and several clinical comorbidities; in contrast, later and lesser vaccine uptake was observed among historically marginalized groups. Whether disparities in COVID-19 vaccination could contribute to disparities in post-COVID-19 conditions merits further investigation.

Abstract Rationale Pulmonary function tests (PFT) are interpreted in the context of reference values that were based on sex, age, height and previously race/ethnicity. The Global Lung Function Initiative (GLI) published spirometry references equations in 2012 and static lung volume reference equations in 2021. In 2023, the American Thoracic Society recommended removal of race from predictive equations for spirometry using the new race-neutral GLI-Global reference equations. Since the change of spirometry reference equations, we have noticed an increase in number of patients with normal spirometry but a low total lung capacity (TLC), where historically the incidence was less than 5 percent and normal spirometry was used to exclude restriction. The goal of this study was to further investigate this observation and characterize the population of patients with normal spirometry and reduced TLC, which we termed occult restriction. Methods We analyzed our existing PFT database which included 28,415 spirometry tests performed at Mayo Clinic Rochester and Mayo Clinic Florida between 2013 to 2016. 26,856 tests included lung volume measurements. The spirometry was interpreted using both GLI-2012 and GLI-Global reference equations and TLC was interpreted using GLI lung volume reference equations. Patients’ demographics including self-identified race were obtained. Patients with occult restriction were further characterized using descriptive statistics. All data analysis was done using BlueSky Statistics Version 10.3.1. Results Our study showed that 920 (3.4%) patients with normal spirometry using GLI-2012 reference equations had low TLC, while 1526 (5.7%) patients with normal spirometry using GLI-Global reference equations had low TLC. Among these patients, 697 patients had a change from abnormal to normal spirometry interpretation and 91 patients had a change from normal to abnormal spirometry interpretation when using GLI-Global reference equations. Comparing patients of different races and ethnicities, there is increased incidence of occult restriction in Caucasian patients with transition to GLI-Global, while the incidence of occult restriction decreased in African American patients. Patients who identify as African American or Southeast Asian are more likely to have occult restriction than others (Table 1). Conclusions With the change from GLI-2012 to GLI-Global spirometry reference equations, the frequency of occult restriction has increased from 3.4% to 5.7% with predominant effect on Caucasian patients. The clinical implication of this finding requires further study but clinicians need to be vigilant that a normal spirometry may not exclude restrictive lung disease using our current reference equations.

Abstract RATIONALE: Allogeneic hematopoietic stem cell transplant (alloHSCT) is the only curative therapy for multiple hematological malignancies and bone marrow failure syndromes. Graft versus host disease (GvHD), remains one of the leading causes of morbidity and mortality. Bronchiolitis obliterans syndrome (BOS) is the canonical manifestation of chronic GvHD of the lungs, occurring in 3-10% of alloHSCT recipients and conferring poor prognosis. There has been a recent paradigm shift towards using post-transplant cyclophosphamide (PTCy) for GvHD prophylaxis resulting in dramatic decreases in both acute and chronic GvHD compared to traditional regimens using methotrexate and tacrolimus. The effect of PTCy on the development of BOS is not well-studied. METHODS: We performed a retrospective cohort study comparing the cumulative incidence of BOS between 93 patients receiving PTCy and 154 patients receiving non-PTCy containing regimens for GvHD prophylaxis between 2015 and 2023 at a single center (Mayo Clinic, Rochester, MN). Patients were included if they were ever diagnosed with BOS or if they survived and were followed for at least 1 year. BOS was diagnosed using 2014 National Institutes of Health criteria. Patients who met 3 of 4 diagnostic criteria were included if a clinical diagnosis of BOS was made. We performed a competing risks time-to-event analysis to compare the incidence of BOS (or death) between the two cohorts. Outcomes were not adjusted for HSCT type (related, unrelated, or haploidentical [HID]) due to a high degree of collinearity with GvHD prophylaxis strategy. RESULTS: Combined cohorts were median age 55 (40-63), 56% male, and 43% ever smokers. Transplants involved HID donors (59% of PTCy cohort, zero non-PTCy), matched related (10% of PTCy, 44% of non-PTCy), matched unrelated (20% of PTCy, 51% of non-PTCy), and mismatched unrelated donors (11% of PTCy, 5% of non-PTCy). Three-year cumulative incidences of BOS among PTCy and non-PTCy recipients were 7% and 14%, respectively (subdistribution HR 0.52 [95% CI 0.21-1.29], P=0.159). For those who received PTCy, incidence of GvHD was smaller (subdistribution HR 0.64 [95% CI 0.46-0.99], P=0.006) with fewer organs involved (1 versus 2, P=<0.0001) and fewer immunosuppressive therapies employed for treatment (2.0 versus 2.5, P=0.01). CONCLUSION: PTCy may reduce risk of BOS among patients undergoing HSCT. Findings are limited by important differences between the cohorts, such as HCT type, and by small sample size. As PTCy is now increasingly used for non-HID transplants, future studies are needed to examine the effect of PTCy on the development of BOS.

Abstract Objective Rare large B-cell lymphomas (LBCLs) present with concurrent or subsequent lymphomatous effusion (solid-effusion LBCL, SE-LBCL), which may have an inferior prognosis compared with their noneffusion counterpart. In addition, the relationship between SE-LBCL and human herpesvirus 8–negative effusion-based LBCL (EB-LBCL) remains unclear. Methods We collected 141 cases of SE-LBCL and a control cohort of 101 cases of stage IV solid-only LBCL. The clinicopathologic features were analyzed and compared between SE-LBCL and solid-only LBCL. Results Patients with SE-LBCL had a median age of 67 years with a male-to-female ratio of 1.3:1. Eighty-six patients had concurrent solid lymphoma and lymphomatous effusion, whereas 55 developed lymphomatous effusion subsequently. Most cases involved the pleural cavities (79%, 112/141), followed by the peritoneal (21%, 29/141) and pericardial (11%, 16/141) cavities. BCL6, CD10, and MUM1 were expressed in 77% (90/117), 46% (60/130), and 61% (58/95) of cases, respectively, and 58% (71/123) were subclassified into the germinal center B-cell (GCB) subtype. Rearrangements of BCL2, BCL6, and MYC were detected in 42% (31/73), 35% (22/63), and 40% (35/88), respectively, and 22% (19/87) had both MYC and BCL2 rearrangements. The patients with SE-LBCL had a dismal prognosis, with a median survival of 5.7 months, which was significantly worse than solid-only LBCL (147.5 months; P < .0001). Conclusions The pathologic features of SE-LBCL were similar to those of solid-only LBCL but distinct from those of EB-LBCL; in particular, lymphomatous effusion was an independently adverse prognostic factor in LBCL. Our study underscores the need for surveillance of lymphomatous effusion during LBCL staging and development of effective therapeutic regimens for SE-LBCL.

Abstract Single-cell sequencing technologies provide us with information at the level of individual cells. Combining single-cell RNA-seq and single-cell TCR-seq profiling enables the exploration of cell heterogeneity and T-cell receptor repertoires simultaneously. Integrating both types of data can play a crucial role in enhancing our understanding of T-cell-mediated immunity and, in turn, facilitate the advancement of immunotherapy. Here, we present immunopipe, a comprehensive and flexible pipeline to perform integrated analysis of scRNA-seq and scTCR-seq data. In addition to the command line tool, we provide a user-friendly web interface for pipeline configuration and execution monitoring, benefiting researchers without extensive programming experience. With its comprehensive functionality and ease of use, immunopipe empowers researchers to uncover valuable insights from scRNA-seq and scTCR-seq data, ultimately advancing the understanding of immune responses and immunotherapy development.

ABSTRACT Renal epithelial cell senescence and kidney aging have become the focus of scientific investigation. However, how epigenetic regulation in these processes remains elusive. Enhancer of zeste homolog 2 (EZH2), a histone methyltransferase, regulates trimethylation of histone H3 at lysine 27 (H3K27me3) and plays an important role in renal pathophysiology. In this study, we show that the expression of EZH2 is decreased in naturally aged and irradiation (IR)‐induced mouse kidneys, as well as in IR‐induced human renal cortical tubular epithelial (RCTE) cells through proteasome‐mediated degradation. Inhibition of EZH2 with its specific inhibitor 3‐DZNeP promotes tubular cell senescence and kidney aging characterized by an increase in the expression of senescence markers, including p16 and p21, in mouse kidneys and in IR‐induced RCTE cells. We show that EZH2 represses the transcription of p16 through trimethylation of H3K27me3, which directly binds to the promoter of p16. EZH2 represses the transcription of p21 through directly binding to the promoter of p21, and this process is involved in its interaction with p53 and its phosphorylation by ataxia‐telangiectasia mutated (ATM), a critical protein involved in the cellular response to DNA damage. Inhibition of ATM with its inhibitor decreased the phosphorylation of EZH2 and the binding of EZH2 to the promoter of p21 in IR‐treated RCTE cells in a p53‐dependent manner. This study suggests that EZH2 plays a critical role in preventing kidney aging and DNA‐damage‐induced renal tubular cellular senescence, in which senescence and kidney aging also result in the destabilization of EZH2, forming a negative feedback loop.

Abstract Objective Glucocorticoid withdrawal syndrome (GWS) may develop in patients following successful surgery for endogenous hypercortisolism. Effective strategies to minimize GWS and improve quality of life (QoL) are currently lacking. We aimed to determine the impact of hydrocortisone vs prednisone therapy on GWS and QoL during the first 12 weeks postsurgery. Methods Single-center prospective cohort study (2019-2024) of adults with endogenous hypercortisolism who developed postoperative adrenal insufficiency and treated with either prednisone or hydrocortisone. Quality of life was assessed with Short Form-36 (SF-36) and Cushing QoL questionnaires at baseline and at 12 weeks postsurgery. GWS was assessed using weekly AddiQoL questionnaires for the first 12 weeks postsurgery. Results Of 165 patients, 101 (61%) were treated with hydrocortisone and 64 (39%) with prednisone. At baseline, no group differences were found in the hypercortisolism subtype, comorbidities, or QoL assessments. At follow-up, no group differences in final total daily hydrocortisone equivalent dose were seen. When adjusting for the baseline QoL assessment, patients treated with prednisone demonstrated a higher degree of improvement in their QoL, particularly in the SF-36 mental component score (estimate 0.33, 95% CI, 0.04-0.63), SF-36 role-emotional limitation (estimate 0.52, 95% CI, 0.2-0.84), and SF-36 body pain (estimate 0.31, 95% CI, 0.07-0.56) subcomponents. In the multivariable analysis of age, sex, body mass index, glucocorticoid type, baseline clinical severity score, and baseline QoL assessment, prednisone therapy was an independent predictor of better SF-36 mental component at 12 weeks postsurgery. Conclusions Prednisone therapy was associated with better mental health QoL than hydrocortisone at 12 weeks postsurgery in patients with hypercortisolism.

METHODS An Expert Panel including patient representation completed a systematic review of the evidence and made recommendations. RESULTS Depending upon prior treatment received, androgen receptor pathway inhibitors (ARPIs: enzalutamide, abiraterone with prednisone), poly(ADP-ribose) polymerase inhibitors (PARPi), chemotherapeutic agents (docetaxel, cabazitaxel), radiopharmaceuticals (radium 223, 177 Lu-prostate-specific membrane antigen [PSMA]-617), and sipuleucel-T have demonstrated an overall survival (OS) benefit for patients with mCRPC. For patients with BRCA1 / 2 alterations who did not receive prior ARPI, the combination of PARPi and ARPI (talazoparib + enzalutamide, olaparib and/or niraparib + abiraterone) has shown clinical benefit. For patients with BRCA1 / 2 alterations who received prior ARPI or ARPI followed by docetaxel, olaparib showed OS benefit. In select patients with microsatellite instability-high/mismatch repair-deficient, pembrolizumab showed clinical efficacy. RECOMMENDATIONS Prior systemic therapy for castration-sensitive prostate cancer will determine subsequent therapy used for mCRPC. Continue androgen-deprivation therapy for patients with mCRPC indefinitely. Early adoption of somatic genetic testing and palliative care is recommended. Patients with mCRPC and bony metastases should receive a bone-protective agent. The panel recommends the combination of ARPI with PARPi in patients with BRCA1 / 2 alterations who did not receive prior ARPI. For patients who received prior ARPI, the panel recommends docetaxel chemotherapy. The panel recommends 177 Lu-PSMA-617 or cabazitaxel chemotherapy for patients who receive prior ARPI and docetaxel chemotherapy. For patients with BRCA1 / 2 alterations who received prior ARPI, the panel recommends PARPi monotherapy. Radium 223 is recommended for patients with symptomatic bone–only disease. Evidence for optimal sequencing for mCRPC regimens is lacking. Additional information is available at www.asco.org/genitourinary-cancer-guidelines .

PURPOSE The combination of the Bruton tyrosine kinase inhibitor ibrutinib with bendamustine-rituximab for first-line treatment of mantle cell lymphoma (MCL) prolonged progression-free survival (PFS), but without improvement in overall survival (OS), likely because of toxicity. Acalabrutinib was shown to be efficacious and less toxic than ibrutinib in a head-to-head trial in chronic lymphocytic leukemia and therefore might lead to better outcomes in MCL. METHODS Patients 65 years and older with previously untreated MCL received acalabrutinib (100 mg twice daily) or placebo (until disease progression or unacceptable toxicity), plus six cycles of bendamustine (90 mg/m 2 once daily; days 1 and 2) and rituximab (375 mg/m 2 as a single dose; day 1) followed by rituximab maintenance in responding patients for 2 years. Crossover to acalabrutinib at disease progression was permitted. The primary end point was PFS per the independent review committee; overall response rate and OS were secondary end points. RESULTS In total, 598 patients were randomly assigned, with 299 in each arm. At a median follow-up of 49.8 months using the reverse Kaplan-Meier method, the median PFS was 66.4 months in the acalabrutinib arm and 49.6 months in the placebo arm (hazard ratio [HR], 0.73 [95% CI, 0.57 to 0.94]; P = .0160). Benefit was seen across all subgroups, including those with high-risk features. Overall response/complete response rates were 91.0%/66.6% and 88.0%/53.5% in the acalabrutinib and placebo arms, respectively. OS was not significantly different (HR, 0.86 [95% CI, 0.65 to 1.13]; P = .27). Grade 3 or greater adverse events were reported in 88.9% and 88.2% in the acalabrutinib and placebo arms, respectively. CONCLUSION The combination of acalabrutinib with bendamustine-rituximab significantly improved PFS. Clinical benefit of acalabrutinib with bendamustine-rituximab was achieved with manageable toxicity.
