Purpose To explore the relationship between systemic comorbidities and presenting tumor T category in patients with uveal melanoma. Methods Single-center, retrospective cohort study of patients with posterior uveal melanoma initially diagnosed between January 2000 and December 2016. Univariate and multivariate ordinal logistic regression analyses were performed to identify comorbidities associated with presenting tumor T category, as classified by AJCC criteria. Results Initial presenting AJCC T category was T1 in 190 (43%), T2 in 130 (29%), T3 in 89 (20%), and T4 in 38 (9%). The most common comorbidities present were hypertension (250 patients, 56%), hyperlipidemia (211, 47%), obesity (137, 31%), and diabetes mellitus (87, 19%). Of these, obesity ( p = 0.034), hypertension ( p = 0.017), and diabetes mellitus ( p < 0.001) were associated with earlier presenting T category on univariate ordinal logistic regression. After multivariate regression, only diabetes mellitus ( p = 0.01) and obesity ( p = 0.04) remained significantly associated with earlier T category on initial presentation. Conclusion Among patients presenting with uveal melanoma, diabetes mellitus and obesity were associated with earlier presenting T category, which could reflect earlier detection of uveal melanoma in patients undergoing annual diabetic retinopathy screening examinations or having more frequent contact with the healthcare system. Larger studies should further explore this association and examine the utility of increased ocular screening in early detection of uveal melanoma.

Abstract High-grade gliomas (HGGs) are aggressive tumors with poor outcomes and limited treatment options. Here, we combined genomic and transcriptomic tumor profiling with drug testing in a patient-derived 3-dimensional culture model to identify individualized treatments and predictive biomarkers. Activity of single agents targeting frequently dysregulated glioma pathways was relatively poor ex vivo and generally reflected historical patient data. However, compounds targeting PI3K, epigenetic, and survival/senescence signaling were effective in some cases. Drug sensitivity correlated with transcriptional rather than genomic features and suggested heterogeneity as a resistance mechanism. Bromodomain and extraterminal domain inhibition was particularly effective in tumors enriched in the mesenchymal transcriptional subtype, promoted proneural transition, and was overcome by upregulated PI3K signaling. Notably, combinations were largely effective, with 6 strategies exhibiting stronger efficacy than corresponding single agents in most cases (58-77%). This study identifies HGG vulnerabilities and associated biomarkers, resistance mechanisms, and effective combination strategies that warrant further clinical validation. Graphical Abstract

Introduction: Underrepresented in family medicine (URiFM) physicians hold 14.42% of US family medicine faculty positions. Scholarship is critical to academic advancement. We explored family medicine department chairs’ racial allyship, their identification of scholarship barriers faced by URiFM faculty, and the existence of initiatives to increase scholarship. Methods: We used the 2022 Council of Academic Family Medicine Educational Research Alliance (CERA) Department Chair survey to examine the percentage of chair-perceived URiFM departmental faculty members and their scholarly productivity and chair-perceived barriers to productivity and initiatives. We measured chairs’ racial allyship. We calculated descriptive statistics, weighted means, and used regression to identify whether chair characteristics or allyship scores were associated with support of URiFM faculty scholarship initiatives and identification of the minority tax. Results: One hundred nine chairs completed the survey (response rate 48.4%); 13.76% identified as URiFM; 6.4% reported they perceived more than 50% of their faculty were URiFM; 90.8% of chairs did not report programs supporting URiFM scholarship; and 44.9% described URiFM faculty scholarly output as minimal or none. Department chairs’ mean allyship score was 2.59 (SD = 0.80) out of 5. Chairs ranked lack of research skills and lack of funding for protected time higher than the minority tax from a list of scholarship barriers. We found no association between chair allyship scores, chair characteristics, total department full-time equivalents, and the existence of a URiFM faculty scholarly support program. Discussion: Despite chairs reporting low URiFM faculty scholarly output, few departments have a dedicated support program. Chair allyship scores were not associated with identification of scholarship barriers or existence of scholarship programs.

Background and Aims: Cholangiocarcinoma (CCA) is a rare but aggressive malignancy with poorly understood genetic susceptibility. To date, genome-wide association studies (GWAS) investigating germline variants associated with CCA risk remain limited. We aimed to identify genetic risk loci for CCA and its clinical subtypes through comprehensive GWAS and post-GWAS analyses. Approach and Results: We conducted a GWAS of 2366 CCA cases and 11,750 controls of European ancestry. Genome-wide significant loci ( p <5×10 −8 ) were identified and further examined through fine-mapping, functional annotation, and HLA imputation. Subgroup analyses were conducted by CCA subtypes and primary sclerosing cholangitis (PSC) status. Cross-trait linkage disequilibrium score regression and Mendelian randomization were employed to investigate the shared genetic architecture and potential causal relationships with a diverse range of traits. We identified 1 new genome-wide significant variant, rs535777 (OR=1.44), near HLA-DRB1/DQA1 associated with CCA, and 2 variants associated with extrahepatic CCA: rs116224263 (OR=0.17) in LINC02506 at 4p15.1 and rs6914950 (OR=1.63) near HLA-DRB1/DQB1 . Stratified analyses revealed rs2395184 (OR=3.51) near HLA-DRA/DRB5 associated with PSC-related CCA, and rs142674434 (OR=2.98) in THSD7A at 7p21.3 associated with non-PSC-related CCA. HLA imputation uncovered new amino acid residues associated with disease risk. Cross-trait analyses identified shared genetic signals between CCA and anthropometric, lipidemic, lifestyle, and medical traits. Mendelian randomization supported putative causal associations for 12 traits with CCA or its subtypes. Conclusions: Our large-scale GWAS highlights new genetic variants and HLA-linked mechanisms underlying CCA susceptibility. Integrating multi-step post-GWAS approaches enhances understanding of CCA pathogenesis and may facilitate the development of risk biomarkers for early detection and precision prevention strategies.

Abstract INTRODUCTION Associations of short‐term use of menopausal hormone therapy (mHT) with Alzheimer's disease (AD) and structural magnetic resonance imaging (MRI) biomarkers were investigated 10 years after an mHT trial. METHODS Recently menopausal women with good cardiovascular health were randomized to oral conjugated equine estrogens (oCEE) or transdermal 17β‐estradiol (tE2) and micronized progesterone, or placebo for 4 years. Amyloid beta (Aβ) on positron emission tomography, hippocampal atrophy, and dorsolateral prefrontal cortex thickness on MRI were assessed 10 years after completion of the mHT trial ( n = 266). RESULTS Aβ and structural MRI biomarkers were not different in the oCEE and tE2 groups compared to placebo. Apolipoprotein E ε4 status did not modify the findings. DISCUSSION There was no evidence of adverse effects or benefits associated with 4 years of use of oral or transdermal mHT on Aβ and structural MRI biomarkers in relatively healthy women, 10 years after mHT. Findings support the long‐term safety of short‐term use of mHT on brain health. CLINICAL TRIALS REGISTRATION NCT00154180 Kronos Early Estrogen Prevention Study (KEEPS) Highlights There were no menopausal hormone therapy–related adverse effects or benefits on amyloid beta and magnetic resonance imaging biomarkers in the long term. Apolipoprotein E ε4 carrier status did not modify these findings. Findings align with neutral cognitive and cerebrovascular outcomes in this cohort.

Background Light chain (AL) amyloidosis is a rare disease caused by the misfolding of immunoglobulin light chains produced by a plasma cell dyscrasia. Patients can present with involvement of many organs, including the heart, kidneys, liver, nerves, and other sites, resulting in a high symptom burden. Timely and accurate diagnosis is important to prevent organ failure and improve patient survival. Objective These evidence-based guidelines of the American Society of Hematology (ASH) are intended to support patients and clinicians in the timely and effective diagnosis of AL amyloidosis. Methods ASH formed a multidisciplinary guideline panel that included 22 individuals representing various medical specialties (academic and community hematology, nephrology, neurology, cardiology, internal medicine, and pathology) as well as 1 patient representative. The group was balanced to minimize potential bias from conflicts of interest. The University of Kansas Medical Center supported the guideline development process, including updating or performing systematic evidence reviews (up to 6 March 2023). The panel prioritized clinical questions and outcomes according to their importance for clinicians and patients. The panel used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, including GRADE evidence-to-decision frameworks, to assess evidence and make recommendations, which were subject to public comment. Results The panel agreed on 12 recommendations. Conclusions The use of serum immunofixation, urine immunofixation, and serum free light chains enhances the clinical suspicion of AL amyloidosis. The diagnosis of AL amyloidosis can be made effectively through surrogate biopsies, which require both a bone marrow biopsy and fat-pad sampling; however, target organ biopsies may be favored in certain clinical situations.

Importance Acute invasive fungal rhinosinusitis (AIFRS) is a rapidly progressive and potentially life-threatening infection that predominantly affects immunocompromised patients. Recent advances in diagnostic imaging, antifungal therapy, and surgical techniques may have altered its incidence, morbidity, and mortality. Objective To evaluate temporal trends in the pooled proportion, morbidity, and mortality of AIFRS in immunocompromised patients and assess the association of diagnostic and therapeutic advances. Data Sources Systematic searches of Ovid MEDLINE, Ovid Embase, PubMed, Scopus, Web of Science, Cochrane, and Google Scholar from 1977 through October 20, 2025, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Study Selection Prospective, retrospective, and cross-sectional studies and case series reporting pooled proportion, morbidity, or mortality of AIFRS in immunocompromised patients were included. Non-English articles, reviews, editorials, and studies with fewer than 10 patients were excluded. Data Extraction and Synthesis Two independent reviewers extracted data using standardized templates; disagreements were resolved by consensus. Risk of bias was assessed using the Newcastle-Ottawa Scale and Murad tool for case series. Random-effects meta-analysis generated pooled proportion, morbidity, and mortality rates with 95% CIs. Heterogeneity was quantified using I 2 statistics. Meta-regression and sensitivity analyses evaluated temporal trends and study-level effects. Main Outcomes and Measures Pooled proportion, morbidity, and mortality rates of AIFRS stratified by publication period (1983-2012 vs 2013-2025). Results A total of 205 studies comprising 48 437 immunocompromised patients (median [range] age, 49.4 [5.2-68.8] years), including 10 311 (21.3%) with AIFRS, were analyzed. The pooled proportion was 11.8% (95% CI, 7.9%-17.2%), rising to 16.6% (95% CI, 8.7%-29.2%) in studies from 2013 to 2025. Overall mortality was 31.2% (95% CI, 28.3%-34.3%), declining from 41.9% (95% CI, 35.0%-49.1%) before 2013 to 28.2% (95% CI, 25.1%-31.4%) after 2013. Morbidity was 37.0% (95% CI, 32.9%-41.4%), with similar rates across periods (39.3% before 2013 vs 36.4% after 2013). The most common complications were vision loss, exophthalmos/proptosis, and orbital exenteration. Conclusions and Relevance This systematic review and meta-analysis suggests that the pooled proportion of AIFRS among immunocompromised patients has increased while mortality has declined, reflecting advances in diagnostic and therapeutic approaches. Early detection and aggressive management remain critical to improving outcomes.

Background In pediatric patients presenting after blunt trauma, the incidence of clinically significant cervical spine injury (CSI) is approximately 1%. Although multidetector CT (MDCT) is widely accepted for cervical spine clearance in adults, its utility in children remains uncertain. The purpose of this study is to evaluate the sensitivity of MDCT in identifying clinically significant CSI in pediatric patients, stratified by age groups: adolescents (12 years to 17 years) and children (0 years to 11 years). Methods We designed a national, multicenter, prospective observational study to assess the diagnostic performance of MDCT in detecting clinically significant CSI in pediatric trauma patients. Data are being collected from participating centers on imaging findings, clinical outcomes, and the presence of confirmed CSIs after blunt trauma. The analysis plan includes stratification by age group and calculation of sensitivity, specificity, and predictive values of MDCT for CSI. Results This abstract outlines the background, methodology, and analytical framework of the study. Data collection and analysis are ongoing. This study represents the largest known cohort of pediatric patients undergoing cervical spine imaging after blunt trauma and is the first prospective study of its kind focused exclusively on this population. Conclusions This study will provide critical data to inform guidelines for pediatric cervical spine clearance after blunt trauma. By evaluating the sensitivity of MDCT in detecting clinically significant CSI, the findings aim to support evidence-based imaging strategies and improve the safety and efficiency of pediatric trauma care.

Abstract Measurable residual disease (MRD) assessment has become central to risk-adapted treatment strategies in multiple myeloma, yet the prognostic value of MRD negativity following autologous stem cell transplantation (ASCT) across individual high-risk cytogenetic abnormalities (HRCAs) remains unclear. We analyzed 351 newly diagnosed patients who achieved MRD negativity (sensitivity 2.4×10 − 6 ) at Day 100 following ASCT and had baseline cytogenetic data available. Median follow-up was 50.4 months. Standard-risk cytogenetics were present in 46% (n = 162), while 34% (n = 118) had one HRCA and 20% (n = 71) had ≥ 2 HRCAs. Despite uniform MRD negativity, several HRCAs continued to confer inferior progression-free survival (PFS). Compared with the standard-risk group (4-year PFS 84%), patients with del(17p), 1q21+, t(4;14), or MAF translocations [t(14;16)/t(14;20)] had significantly lower 4-year PFS rates: 56% (HR 2.89; p = 0.0001), 60% (HR 2.46; p = 0.0001), 43% (HR 3.50; p = 0.0001), and 58% (HR 2.51; p = 0.01), respectively. Isolated del(17p) and 1q21 + also conferred inferior PFS. The 4-year PFS was 65% for patients with one HRCA (HR 2.31; p = 0.0004) and 55% for those with ≥ 2 HRCAs (HR 2.75; p = 0.0001). In this large MRD-negative post-ASCT cohort, several HRCAs, including isolated HRCAs, remained clinically meaningful drivers of inferior PFS, highlighting that early MRD negativity does not uniformly mitigate the impact of high-risk biology.
