Abstract Family history of hematologic malignancy (FHHM) is an established risk factor for developing lymphoma, but studies examining associations between self-reported FHHM and lymphoma prognosis during the recent treatment era are limited. Utilizing a prospective cohort study, we evaluated associations between FHHM and prognosis for common lymphoma subtypes, including diffuse large B-cell (DLBCL), follicular (FL), marginal zone (MZL), mantle cell (MCL), Hodgkin (HL), and T-cell (TCL) lymphomas. We used the Mayo Clinic component of the Molecular Epidemiology Resource, a prospective cohort study of newly diagnosed lymphoma patients enrolled from 2002 to 2015. Self-reported FHHM (HL, NHL, leukemia, or multiple myeloma) in a first-degree relative was obtained via questionnaire. Primary outcomes were overall survival (OS) and event-free survival (EFS; time from diagnosis to disease progression, initiation of second-line therapy, or all-cause death). Secondary outcomes were failure to achieve 24 months of event-free survival (EFS24; associated with aggressive disease and poor outcomes) and lymphoma-specific survival (LSS; time from diagnosis to death from lymphoma or lymphoma treatment-related complications). We used multivariable Cox proportional hazards regression to estimate hazard ratios (HRs) and 95% confidence intervals (CI) for the association of FHHM with OS, EFS, and LSS, and logistic regression to estimate odds ratios (ORs) and 95% CI for the association with failure to achieve EFS24. All models were adjusted for sex and a lymphoma subtype specific prognostic index. The cohort consisted of 650 DLBCL, 679 FL, 291 MZL, 178 MCL, 254 HL, and 196 TCL patients. The prevalence of FHHM ranged from 9.7% in TCL to 14% in FL. FHHM was not associated with OS in any subtype, but MCL patients with FHHM showed an inferior EFS (HR=1.70, 95% CI 1.02-2.85; p=0.04). For EFS24, FHHM was associated with failure to achieve EFS24 only in FL (OR=1.57, 95% CI 0.99-2.48; p=0.05). Similarly, FHHM was associated with inferior LSS in FL patients (HR=1.98, 95% CI 1.11-3.53; p=0.02). In a treatment subgroup analysis of FL patients, the FHHM associations with failure to achieve EFS24 (OR=2.48, 95% CI 1.04-5.74; p=0.04) and inferior LSS (HR=2.68, 95% CI 1.09-6.58; p=0.03) strengthened among those treated with frontline immunochemotherapy (IC). In summary, there were no evidence of associations between FHHM and OS across lymphoma subtypes, but MCL patients with FHHM displayed inferior EFS. FL patients with FHHM were more likely to not achieve EFS24 and to ultimately die of their lymphoma or a lymphoma treatment-related complication. This finding was stronger in more aggressive FL requiring frontline IC. This novel finding would suggest that genetic or environmental factors associated with FHHM may underlie pathways that impact disease aggressiveness and early clinical failure in FL.

Abstract: A 49-year-old short-board goofy-stance competitive surfer presented with a 3-month history of bilateral, left foot pain associated with tender soft tissue plantar nodules. Magnetic resonance imaging of the left foot revealed foci of fibrotic tissue within the subcutaneous tissue adjacent to the first and fifth metatarsophalangeal joints compatible with surfers' knots . The patient underwent conservative treatment with oral ibuprofen as needed before competitions, topical diclofenac gel, wide toe box shoes, and use of a double-thick traction pad on his surfboard to alleviate the friction between the metatarsophalangeal joints of his left foot and the surfboard. He reported improvement of symptoms and full return to surfing at 8-month follow-up. We present a case of surfers' knots overlying the left first and fifth metatarsophalangeal joints of a male competitive surfer and highlight recommendations for successful conservative treatment options for symptomatic athletes.

Objectives/Goals: To assess the attitudes toward social justice of residents and faculty following the didactic series and evaluate the impact of the longitudinal curriculum on resident engagement in social justice activities through community engagements. Methods/Study Population: Data were gathered through questionnaires collected from participating residents and faculty. The session topics were chosen based on “Precepting Toward Social Justice” curriculum from the University of Minnesota Department of Family Medicine and Community Health, including sessions on advocacy, diversity, and implicit bias, among others. The self-assessment questionnaires were specific to the topics of the lecture, assessing knowledge, skills, and attitudes before and after the education sessions. Participants were asked to rate these aptitudes of each topic from “none” to “expert.” Results/Anticipated Results: Out of 22 total participants, 16 returned surveys. Overall, there was a substantial improvement in aptitudes after the lecture. There was an increase in reported above average knowledge of topics: Agency (12.5% to 56.25%), Humility (18.75% to 62.5%), Dignity (12.5% to 62.5%), Partner (18.75% to 50%), Awaken (37.5% to 75%), Place (12.5% to 43.75%), Asset (0% to 37.5%), Sanctuary (6.25% to 50%), Belonging (0% to 37.5%), Whole (0% to 43.75%), Liberation (12.5% to 68.75%), and Heal (37.5% to 75%). 31% reported that the lectures alone had an above average influence on pursuing more social justice activities through community engagement. 44% reported that the lectures had an above average impact on their subsequent patient encounters. 69% stated that this series helped develop their overall social justice skills. Discussion/Significance of Impact: All patients deserve equitable care. Family physicians have a unique role in addressing social justice concerns to eliminate inequalities and drive for better health outcomes. By enforcing social justice in education and implementing it into practice, satisfaction, trust, and well-being of patient and provider will be improved.

AbstractBackgroundThe 17q21.31 region with various structural forms characterized by the H1/H2 haplotypes and three large copy number variations (CNVs) represents the strongest risk locus in progressive supranuclear palsy (PSP).ObjectiveTo investigate the association between CNVs and structural forms on 17q.21.31 with the risk of PSP.MethodsUtilizing whole genome sequencing data from 1684 PSP cases and 2392 controls, the three large CNVs (α, β, and γ) and structural forms within 17q21.31 were identified and analyzed for their association with PSP.ResultsWe found that the copy number of γ was associated with increased PSP risk (odds ratio [OR] = 1.10, P = 0.0018). From H1β1γ1 (OR = 1.21) and H1β2γ1 (OR = 1.24) to H1β1γ4 (OR = 1.57), structural forms of H1 with additional copies of γ displayed a higher risk for PSP. The frequency of the risk sub‐haplotype H1c rises from 1% in individuals with two γ copies to 88% in those with eight copies. Additionally, γ duplication up‐regulates expression of ARL17B, LRRC37A/LRRC37A2, and NSFP1, while down‐regulating KANSL1. Single‐nucleus RNA‐seq of the dorsolateral prefrontal cortex analysis reveals γ duplication primarily up‐regulates LRRC37A/LRRC37A2 in neuronal cells.ConclusionsThe copy number of γ is associated with the risk of PSP after adjusting for H1/H2, indicating that the complex structure at 17q21.31 is an important consideration when evaluating the genetic risk of PSP. © 2025 The Author(s).

Abstract Background and Aims Over 10% of patients with Crohn’s disease require permanent ileostomy. We aimed to summarize the existing data on diagnosis, definitions of recurrence, and management of Crohn’s disease patients with permanent ileostomy. Methods MEDLINE, Embase, and CENTRAL databases were searched from inception to February 6, 2024. Randomized controlled trials, cohort and cross-sectional studies, and case series of more than 5 patients reporting on postoperative recurrence or the need for surgery in patients with Crohn’s disease and permanent ileostomy were included. Search results were independently screened, and full text of all titles meeting eligibility criteria was obtained. Outcomes of interest included diagnostic techniques, recurrence definitions, and management approaches. We estimated pooled rates (with 95% confidence interval [CI]) of recurrence. Results Thirty cohort studies including 2055 Crohn’s patients with permanent ileostomy were included (53% female, median age at the time of ileostomy creation 32 years, the most common reason for ileostomy was refractory disease). The postoperative recurrence rate was 27% (95% CI, 21.3–33.3, 26 studies, 451/1805 patients). Modalities for diagnosis of Crohn’s disease recurrence were symptoms (15 studies), endoscopy (4 studies), histology from endoscopic biopsies (2 studies), imaging (5 studies), and surgery (22 studies). The reported definitions of recurrence for each modality were heterogeneous. Conclusions There is a lack of standardized monitoring tools and criteria for diagnosing recurrence in patients with Crohn’s disease and permanent ileostomy. The results of this systematic review will form the basis of a global expert recommendation exercise focused on developing management standards and trial endpoints for this condition.

BACKGROUND: Hypertensive disorders of pregnancy (HDP) are a major cause of maternal morbidity and mortality and are associated with acute cardiac events in the peripartum period, as well as cardiovascular disease later in life. Despite the robust association between hypertension and atrial fibrillation (AFib), comparatively little is known about HDP and its subtypes as sex-specific risk factors for AFib. METHODS: A population-based retrospective cohort study was conducted, including 771 521 nulliparous women discharged for obstetrical delivery of their first live or stillborn singleton infant between 2002 and 2017 in Ontario, Canada. Data were obtained from record-level, coded, and linked population-based administrative databases housed at ICES. Using competing risks Cox proportional hazards regression, we estimated crude and multivariable-adjusted cause-specific hazard ratios and 95% CIs for associations between history of any HDP (and its 6 subtypes), and AFib before death, as well as all-cause mortality without a previous AFib diagnosis. RESULTS: Approximately 8% of women were diagnosed with HDP during the 16-year exposure accrual period. The total person-time of follow-up was 7 380 304 person-years, during which there were 2483 (0.3%) incident AFib diagnoses and 2951 (0.4%) deaths. History of any HDP was associated with an increased cause-specific hazard ratios of incident AFib and death without a previous AFib diagnosis (adjusted cause-specific hazard ratios, 1.45 [95% CI, 1.28–1.64] and 1.31 [95% CI, 1.16–1.47], respectively). These associations were observed in relatively young women (median time to event, 7 years postpartum). Associations suggestive of a dose-response relationship were observed, with more severe HDP subtypes and prepregnancy chronic hypertension associated with a 1.5 to 2.2 times higher cause-specific rate of AFib, and a 1.4 to 2.1 times higher cause-specific rate of death compared with no hypertension in pregnancy. CONCLUSIONS: Women exposed to HDP in their first delivery have a significantly increased cause-specific hazard ratios of incident AFib compared to their unexposed counterparts, with higher rates observed in subjects exposed to more severe de novo HDP diagnoses as well as chronic hypertension in pregnancy. These findings underscore the need to consider HDP history in risk calculation/stratification for arrhythmic and nonarrhythmic cardiovascular diseases, improve surveillance of traditional and female-specific cardiovascular disease risk factors, and develop targeted prevention strategies to reduce the occurrence and burden of HDP.

Background and Objectives: Physician scheduling affects job satisfaction and retention. This study explores how family medicine residency inpatient staffing relates to core faculty retention and program director (PD) perception of faculty satisfaction with work-life integration. Methods: A total of 280 family medicine residency PDs responded to the 2023 Council of Academic Family Medicine Education Research Alliance survey. We used the ꭓ2 test to explore associations among program demographics, inpatient staffing characteristics, faculty retention, and PD-reported faculty satisfaction with work-life integration. We measured associations among pairs of ordinal variables with Spearman’s correlation. Results: In two-thirds (66%) of programs, faculty cover the inpatient service at least every 8 weeks, with 40% of programs reporting averages of 70 or more hours per inpatient week; nevertheless, most programs’ faculty were perceived to be satisfied with less than 10% turnover. The number of hours per week was inversely associated with PD-reported faculty satisfaction (r=-0.21, P=.001). Faculty turnover was directly associated with community size (r=0.17, P=.01). Faculty turnover was more likely to be greater than 10% if the number of hours per inpatient week was more than 89 (odds ratio 12.4, P=.02). Faculty turnover, PD-reported faculty dissatisfaction, and plans to change inpatient staffing were all correlated (r>0.28, P<.0001). Conclusions: Most family medicine residencies have core faculty cover the inpatient service at least once every 8 weeks, during which they work at least 60 hours per week. Longer hours are associated with lower perceived faculty satisfaction of work-life integration, with a threshold effect on faculty turnover. Family medicine residency programs must carefully balance the needs of residents, the community served, and faculty themselves.
