Introduction: Over 80,000 new cases of Non-Hodgkin's Lymphoma (NHL) are diagnosed annually, but modifiable risk factors are largely unknown. Circadian disruption has been identified as a risk factor for several cancers, including breast and prostate cancer, and affects immune cells such as Natural Killer (NK) cells and T-helper cells. Disruptions in circadian rhythms can lead to aberrant immune cell trafficking and proliferation. Despite this biological connection, evidence linking circadian disruptions to NHL remains inconclusive. Only single Mendelian Randomization (MR) study (PMID: 32895918) has explored the causal relationship between sleep traits and overall NHL risk, without examining NHL subtypes. Studies have shown distinct risk factor profiles among NHL subtypes. Therefore, this study aims to investigate the causal relationship between sleep traits and NHL subtypes in European populations using MR. Methods: We conducted a two-sample MR analyses using genome-wide association studies (GWAS) summary data on sleep traits and NHL subtypes. The GWAS summary statistics on sleep traits were obtained from publicly available UKBiobank datasets. The sleep traits analyzed included chronotype (N=449,734), insomnia (N=237,627), sleep duration (N=446,118), daytime sleepiness (N=452,071), short sleep (N=411,934), and long sleep (N=339,926). Only independent, genome-wide significant SNPs (p < 5×10-8) were considered as valid instruments. The NHL subtype-specific summary statistics came from the InterLymph including follicular lymphoma (FL: N=6,508 cases / 64,183 controls), mantle cell lymphoma (MCL: N=1,169 cases / 61,603 controls), and Waldenström macroglobulinemia/lymphoplasmacytic lymphoma (WM/LPL: N=1,697 cases / 59,333 controls). Our primary analysis used the random-effects inverse-variance weighted (IVW) method. In addition, we employed MR-Egger to adjust for directional pleiotropy. Heterogeneity in the MR results was evaluated with Cochran's Q statistic. Results: The IVW method did not identify any statistically significant causal association between sleep traits and the risk of NHL subtypes (FL,MCL,WM/LPL), but did yield several intriguing associations. Chronotype (early rising) showed a tendency towards a marginally an increased NHL risk across subtypes [Odds ratio (OR) range: 1.07 - 2.56]. Conversely, a decreased risk was noted for long sleep (≥ 9 hours vs. 7-8 hours) [OR range: 0.19 - 0.62], insomnia [OR range: 0.72 - 0.88], and short sleep (excludes MCL) [OR range: 0.12 - 0.72]. Confidence limit for long sleep was wide due to small number of variants (N=8). The MR-Egger regression analysis did not provide evidence of significant directional horizontal pleiotropy. The F-statistics for all sleep traits were greater than 10 indicating absences of weak instrument bias. Conclusions: Our study found no statistically significant associations between sleep traits and three NHL subtypes (FL, MCL, WM/LPL) in European populations. However, we observed potential influences of chronotype, long and short sleep, and insomnia on NHL risk. These findings align with and extend previous MR study by providing subtype-specific insights. Future directions include expanding our analysis to additional NHL subtypes, generating polygenic risk scores, and conducting stratified analyses using the InterLymph population. These efforts aim to further elucidate the complex relationship between sleep characteristics and NHL risk across diverse subtypes and populations.

Abstract Background Recurrent pericarditis (RP) is a chronic autoinflammatory disease mediated by IL-1 that requires long-term treatment. While the 2015 European Society of Cardiology Guidelines position IL-1 pathway inhibition only after corticosteroids, complications associated with long-term steroid use underscore the importance of steroid-sparing strategies. Rilonacept, an IL-1α and IL-1β cytokine trap, is the only FDA-approved treatment for RP (available since April 2021). RESONANCE, an ongoing 5-year non-interventional US registry of patients (pts) with RP, has collected real-world data from pts cared for by cardiologists with a focus on pericardial disease, with a goal of informing contemporary RP clinical management. Purpose Analysis of temporal trends in RP management from RESONANCE. Methods From a database cut-off (DCO) on 21 December 2023, patient demographics and disease characteristics are reported for 242 active RP pts (excluding RHAPSODY prior participants) at 20 US sites (median [Q1:Q3] 2.1 [1.5:2.6] years and 556 patient-years [PY] of observation). Complete medication class use data were available for 239 pts (total 546 PY). Proportional medication class use prior to initiating rilonacept was analyzed annually across the observation period. Results Mean (standard deviation) age at DCO was 50.2 (16.6) years; 58.1% were female. Median [Q1:Q3] disease duration at DCO from index pericarditis episode was 3.1 [2.2:5] years. Median [Q1:Q3] number of prior recurrences at enrollment was 3 [2:5]. Prior to rilonacept availability, NSAIDs/Colchicine/Aspirin represented the highest proportion of treatment (73% of PY); steroid use was 9% of PY, IL-1 pathway inhibition (anakinra) was 13% of PY, and conventional synthetic disease modifying antirheumatic drugs (csDMARDs) were 0.46% PY (no RP-specific treatment was 5% of PY) (Fig 1). In the years since rilonacept availability, proportional IL-1 pathway inhibition use has increased, from 13% of PY in 2020-21 to 26% of PY in 2023, driven by an increase in rilonacept use (6%, 13%, 16% of PY in 2021, 2022, and 2023, respectively). Over that same period, proportional NSAIDs/Colchicine/Aspirin use (57%-63% of PY) has been consistently 6-times more than proportional steroid use (10%-11% of PY). Among pts who initiated rilonacept (n=81), similar proportions transitioned from NSAIDs/Colchicine/Aspirin as from corticosteroids (Fig 2), a robust trend observed each year. Of those pts transitioning from corticosteroids, 1/3 had used corticosteroids for <30 days and 1/3 for >6 months. Conclusions Real-world data from the RESONANCE registry reveal a temporal shift in RP management in US centers with RP-focused cardiologists, with increased proportional IL-1 pathway inhibition use since rilonacept availability in 2021. Advancing beyond 2015 guideline recommendations, IL-1 pathway inhibition is often being used as steroid-sparing treatment, i.e., after colchicine instead of chronic corticosteroids.

Introduction The implementation of cervical cancer screening and human papillomavirus (HPV) vaccination has significantly reduced cervical cancer rates. However, it remains the fourth most common cancer among women globally. Barriers to screening include personal, health system, and insurance factors. Methods To address these barriers, a “Saturday Pap smear Clinic” was established to increase accessibility. The study included female patients aged 21 to 65 from Southeast Minnesota, USA, who attended the clinic from September 2021 to April 2023. Results A total of 357 women attended the Saturday clinic, with a median age of 44 years; 70.6% were White. Abnormal Pap smear results were found in 13.8% of attendees, with 7.8% testing positive for HPV. Additional health maintenance was addressed. The majority of patients had a physician primary care provider (58.3%), followed by residents (26.3%), and nurse practitioner/physician associates (15.4%). Discussion The clinic demonstrated a high fill rate of 86.15%, indicating demand for non-traditional appointment times. Despite this, disparities in access were noted, with primarily White and English-speaking women utilizing the clinic. The clinic showed improved outcomes compared to national screening rates, highlighting the importance of timely preventative care.

ABSTRACT Background and Objectives Hepatic epithelioid hemangioendothelioma (HEHE) is an uncommon vascular neoplasm characterized by variable clinical behavior. Our aim was to describe the therapeutic approach for HEHE at diagnosis and define clinicopathological characteristics associated with tumor progression and long‐term survival. Methods This is a retrospective study that includes patients with HEHE who received treatment at Mayo Clinic Rochester between 1984 and 2023. Results Eighty patients were included in the study (median age: 44 years; 62.5% female), 24 underwent liver transplantation, 26 underwent liver resection, and 30 were managed medically. The 3‐year overall survival rates were 86.7%, 80.9%, and 51.1%, respectively. Notably, 26 patients had extrahepatic metastases at the time of diagnosis, four (16.7%) in the transplantation group, four (15.4%) in the resection group, and 18 (69.2%) in the nonsurgical group. On multivariable modeling, bone metastasis was independently associated with long‐term mortality (HR 6.3, p < 0.001) while lung metastasis and surgical intervention were not associated with long‐term mortality (HR 0.8, p = 0.8; HR 1.1, p = 0.9, respectively). Conclusion Bone metastasis emerged as a strong predictor of poor survival. Hence, aggressive surgical intervention may not be advantageous in patients with skeletal metastases but can still be offered for those with other extrahepatic metastases.

Background: Myxoid liposarcoma predominantly affects young and middle-aged individuals, and little is known regarding treatment tolerability and outcomes in older patients. This study aims to better understand this older patient population. Methods: This single institution retrospective study included patients aged 70 years and older with localized (non-metastatic) myxoid liposarcoma. Results: Sixteen patients were included. The median age was 75 years, and 9 (56%) were female. Fourteen (88%) were extremity tumors and two (12%) were trunk. The median tumor size was 10.4 cm (range, 3.6 to 28 cm). Five (31%) tumors had a round cell component. All patients had surgery. Fourteen (88%) had perioperative radiation, and three (19%) had perioperative chemotherapy. One patient had postoperative infection, and one patient had neutropenic fever from preoperative chemotherapy. The median follow up from surgery was 6.3 years. Eight (50%) patients died from MLPS. The median relapse-free survival and overall survival were 34 months and 75 months, respectively. Conclusions: Most older patients with localized MLPS received perioperative radiation therapy with surgery, and few serious toxicities were reported. Even with treatment, half of the patients relapsed.

Abstract Introduction: In an effort to ensure an all-inclusive initiative that would close the disparity gap among the immigrant communities in Florida, we developed a pilot project under the Inclusive Cancer Care Research Equity (iCCaRE) for Black Men Consortium with generous support from the Mayo Clinic Comprehensive Cancer Center (MCCCC). The objective is to train cancer advocates to engage their communities and develop and implement cancer prevention and screening navigation programs. The central hypothesis for this program is that community-driven cancer advocacy will significantly improve cancer awareness, knowledge, prevention, risk reduction, screening uptake, and early detection among Black immigrants. Methods: We collaborated with immigrant communities’ leaders to brainstorm on the current state of healthcare access and disparities experienced by Black immigrants and to set program and research priorities through listening sessions. Cancer advocates were trained to engage their communities to (1) develop and implement cancer risk reduction and education programs using train-the-trainer approach, (2) mobilize the resources within the community for cancer health promotion, prevention, and screening strategies, (3) partner with key stakeholders to accomplish targeted objectives; (4) raise funds to support advocacy activities; and (5) develop and successfully organize community-centered programs. Results: We are currently working with 10 Black immigrant organizations, including immigrant churches across different ethnicities, including Nigeria, Ghana, Cameroon, Liberia, South Africa, Haiti, Jamaica, and across different cities in the United States. Eighteen community cancer advocates, including breast and prostate cancer survivors, caregivers, and community influencers, were trained to engage the immigrant communities in cancer risk reduction and research in Florida using multiple channels, including in-person community programs and online engagement approaches. We have engaged 720 immigrants in cancer risk reduction education and the need to participate in research during advocate-led in-person community outreaches. We currently have 26 immigrants who have volunteered in the Mayo Clinic Community Research Registry. The program is ongoing, and we anticipate that more than 750 will be engaged, and 100 will volunteer to be registered in the Mayo Clinic Community Research Registry. Conclusion: Advocate-led advocacy in immigrant communities will provide evidence for compelling arguments about the feasibility and availability of the Black immigrant population for robust and sustainable research and program engagements to eliminate disparity and advance cancer health equity.

Importance The role of air pollution in risk and progression of Parkinson disease (PD) is unclear. Objective To assess whether air pollution is associated with increased risk of PD and clinical characteristics of PD. Design, Setting, and Participants This population-based case-control study included patients with PD and matched controls from the Rochester Epidemiology Project from 1998 to 2015. Data were analyzed from January to June 2024. Exposures Mean annual exposure to particulate matter with a diameter of 2.5 µm or less (PM 2.5 ) from 1998 to 2015 and mean annual exposure to nitrogen dioxide (NO 2 ) from 2000 to 2014. Main Outcomes and Measures Outcomes of interest were PD risk, all-cause mortality, presence of tremor-predominant vs akinetic rigid PD, and development of dyskinesia. Models were adjusted for age, sex, race and ethnicity, year of index, and urban vs rural residence. Results A total of 346 patients with PD (median [IQR] age 72 [65-80] years; 216 [62.4%] male) were identified and matched on age and sex with 4813 controls (median [IQR] age, 72 [65-79] years, 2946 [61.2%] male). Greater PM 2.5 exposure was associated with increased PD risk, and this risk was greatest after restricting to populations within metropolitan cores (odds ratio [OR], 1.23; 95% CI, 1.11-1.35) for the top quintile of PM 2.5 exposure compared with the bottom quintile. Greater NO 2 exposure was also associated with increased PD risk when comparing the top quintile with the bottom quintile (OR, 1.13; 95% CI, 1.07-1.19). Air pollution was associated with a 36% increased risk of akinetic rigid presentation (OR per each 1-μg/m 3 increase in PM 2.5 , 1.36; 95% CI, 1.02-1.80). In analyses among patients with PD only, higher PM 2.5 exposure was associated with greater risk for developing dyskinesia (HR per 1-μg/m 3 increase in PM 2.5 , 1.42; 95% CI, 1.17-1.73), as was increased NO 2 exposure (HR per 1 μg/m 3 increase in NO 2 , 1.13; 95% CI, 1.06-1.19). There was no association between PM 2.5 and all-cause mortality among patients with PD. Conclusions and Relevance In this case-control study of air pollution and PD, higher levels of PM 2.5 and NO 2 exposure were associated with increased risk of PD; also, higher levels of PM 2.5 exposure were associated with increased risk of developing akinetic rigid PD and dyskinesia compared with patients with PD exposed to lower levels. These findings suggest that reducing air pollution may reduce risk of PD, modify the PD phenotype, and reduce risk of dyskinesia.

Background: Synovial sarcoma is rare and may present as a small, slow-growing mass. These tumors are often mistaken as benign and are therefore prone to unplanned and/or non-oncologic excision. We sought to identify the rate of unplanned excision of synovial sarcoma and risk factors for recurrence and survival among this cohort. Methods: The medical records of 246 patients evaluated at a single institution for synovial sarcoma between 1997 and 2022 were retrospectively reviewed. Of these, 87 (35%) underwent unplanned, non-oncologic excision. The mean age of the cohort was 49 years. Primary tumors were located in the extremity (n = 63), abdomen (n = 6), thorax (n = 7), head/neck (n = 8), and paraspinal region (n = 3). The median maximum pre-treatment dimension of the primary tumor was 4.8 cm (IQR 7–2.4). Seventy-seven (86%) patients underwent re-excision of the tumor bed, 39 (45%) received chemotherapy, and 63 (72%) received radiation therapy. Results: Among patients who underwent unplanned excision, local recurrence-free survival (LRFS) was 98% at 1 year and 82% at 5 years. Metastasis-free survival (MFS) was 91% at 1 year and 72% at 5 years. Disease-specific survival (DSS) was 98% at 1 year and 72% at 5 years. When adjusting for tumor size, tumors which underwent unplanned excision did not have worse recurrence or survival compared to those which had planned excision (p > 0.10). Size > 5 cm, monophasic subtype, and axial location were associated with increased risk of disease recurrence. Forty-six patients had residual tumor following re-excision, which was associated with worse MFS (HR 8.17, 95% CI [1.89, 35.2], p < 0.01) and DSS (HR 7.66, 95% CI [1.76, 33.4], p < 0.01). Patients who received radiotherapy had improved MFS (HR 6.4, 95% CI [1.42, 29.0], p = 0.02) and DSS (HR 5.86, 95% CI [1.27, 26.9], p = 0.02). Conclusions: One-third of patients presenting with synovial sarcoma were diagnosed after unplanned, non-oncologic excision. Patients with large, axial tumors had worse survival. Approximately half of patients who underwent unplanned excision had no residual tumor after pre-operative radiation. The use of radiation was associated with decreased rates of recurrence and improved disease-specific survival. Our results suggest that margin-negative re-resection and radiotherapy should be considered when feasible following unplanned excision of synovial sarcoma.
