Importance Standard adjuvant therapy for human papillomavirus–associated oropharyngeal squamous cell carcinoma (HPV-OPSCC) is radiation therapy 60 Gy with or without cisplatin delivered in 30 fractions during 6 weeks. A phase 3 randomized clinical trial demonstrated decreased toxic effects and improved patient-reported outcomes with de-escalated adjuvant radiation therapy (DART) compared with standard therapy; however, outcomes for patients treated in the clinical practice setting following trial adoption remain unknown. Objective To compare characteristics and oncologic outcomes of patients treated with DART during clinical trials (on study) and in clinical practice settings (off study) and report progression-free survival (PFS) by risk category. Design, Setting, and Participants This retrospective cohort study included patients treated with DART in the MC1273 and MC1675 trials and in clinical practice after study completion at a multisite tertiary care center. Patients with surgically resectable HPV-OPSCC who underwent margin-negative resection between August 20, 2013, and March 21, 2023, and were treated with DART were included in the analysis. Those with prior head and neck cancer, pT0 or pT4 disease, unknown HPV status, metastatic disease at presentation, synchronous primary tumors, induction chemotherapy, or treatment at an outside institution were excluded. Data were analyzed from July 1, 2024, to July 18, 2025. Interventions DART consisting of 30 to 36 Gy in 1.5- to 1.8-Gy fractions twice daily with docetaxel 15 mg/m 2 on days 1 and 8. Main Outcomes and Measures Progression-free survival as measured via Kaplan-Meier analysis. Results A total of 282 patients were included in the analysis: 176 (62.4%) in the on-study group and 106 (37.6%) in the off-study group (252 [89.4%] male; mean [SD] age, 59.1 [9.3] years). Both groups were predominantly male (157 [89.2%] and 95 [89.6%], respectively) and consisted mostly of never smokers (118 [67.0%] and 62 [58.5%], respectively). Pathologic features were similar between groups except for nodal stage (pN1: 155 [88.1%] on study vs 102 [96.2%] off study; pN2: 21 [11.9%] on study vs 4 [3.8%] off study; P = .02). The median follow-up times were 5.2 years (95% CI, 5.2-5.8 years) in the on-study group and 2.2 years (95% CI, 1.9-2.4 years) in the off-study group. Two-year PFS was similar (93% [95% CI, 88%-97%] on study vs 93% [95% CI, 88%-99%] off study). For patients with pN1 and no extranodal extension (ENE), 2- and 5-year PFS were 97% (95% CI, 93%-100%) and 96% (95% CI, 92%-100%), respectively. Patients with pN1 and ENE had a 2- and 5-year PFS of 93% (95% CI, 89%-98%) and 87% (95% CI, 81%-94%), respectively. Conclusions and Relevance In this retrospective cohort study of patients receiving DART on and off study, oncologic outcomes were similar between the 2 groups. Fewer patients with pN2 received DART off study, given the interim results of MC1675. Patients with pN1 and no ENE treated with DART had excellent 2- and 5-year PFS, supporting DART as a compelling treatment option in well-selected patients. An additional study that is currently underway will evaluate biomarker risk-stratified treatment of patients with pN1 and ENE receiving DART.

Preeclampsia (PE) is a multifactorial hypertensive disorder of pregnancy that significantly increases both short- and long-term cardiovascular risk for affected women. PE and cardiovascular disease (CVD) share common risk factors, including endothelial dysfunction, obesity, insulin resistance, and dyslipidemia. Women with a history of PE face a markedly elevated risk of chronic hypertension, heart failure, and adverse cardiac remodeling, with evidence suggestive of persistent vascular and myocardial changes after pregnancy. The complex pathophysiology of PE is multifactorial and is thought to involve a combination of abnormal placentation, immune dysregulation, and anti-angiogenic factors, which may induce permanent cardiovascular alterations. Genetic predispositions may further link PE with cardiomyopathies and peripartum cardiomyopathy. However, despite these well-established risks, standardized long-term surveillance and management strategies for women with prior PE remain lacking. Early identification and targeted intervention in women with a history of PE represent critical opportunities to mitigate future cardiovascular morbidity and mortality. This review highlights the urgent need for comprehensive, evidence-based strategies that incorporate personalized follow-up and risk stratification to improve cardiovascular outcomes in this high-risk population.

OBJECTIVES We aimed to characterize the frequency of major complications of acute COVID-19 and multisystem inflammatory syndrome in children (MIS-C) and adolescents present at 6 months after initial presentation. METHODS The Pediatric Research Immune Network on SARS-CoV-2 and MIS-C (PRISM) study was a prospective cohort at 20 US pediatric academic medical centers. Individuals aged younger than 21 years meeting any of the following were enrolled: SARS-CoV-2 detection within 7 days, Centers for Disease Control and Prevention (CDC) MIS-C criteria, or CDC MIS-C criteria except having involvement of 1 organ system. The study was designed to assess the proportion of children with major complications (cardiovascular, pulmonary, gastrointestinal/hepatic, renal, and/or neurologic) 6 months after presentation. RESULTS Data were analyzed on 229 hospitalized participants: 59 with COVID-19 (mean age 10.4 years; SD, 5.5) and 170 with MIS-C (mean age 10.1 years; SD, 4.8). Overall, 42.8% were female, making up 55.9% and 38.2% of the COVID-19 and MIS-C groups, respectively. Overall, the frequencies of major complications at 6 months after initial presentation were: 16/195 (8.2%) cardiovascular, 11/154 (7.1%) pulmonary, 11/154 (7.1%) gastrointestinal/hepatic, 3/152 (2.0%) renal, and 3/189 (1.6%) neurologic. Organ system complications did not differ significantly between the COVID-19 and MIS-C groups. Six of 14 (42.9%) COVID-19 and 21/26 (80.7%) MIS-C participants with at least 1 six-month complication had no underlying medical condition that may have been associated with their complication(s). CONCLUSIONS Major complications were infrequent but observed in children without underlying medical conditions, underscoring the importance of prospective follow-up to optimize management and elucidate the complications associated with severe SARS-CoV-2 infection in children.

RELA-related disease is a rare, autosomal-dominant condition presenting with immune dysregulation and immunodeficiency. RELA encodes the p65 subunit, a component of the canonical NFκB pathway. The underlying pathogenesis, at least in part, involves impaired NFκB activation, increased susceptibility to TNFα-induced apoptosis, and hyperinflammation. To date, only a modest number of cases have been documented worldwide, and the full clinical and functional spectrum of disease remains incompletely defined. This study represents a large global cohort identified with RELA variants, comprising 40 patients from 30 institutions, expanding our previous report of a single large kindred (1). The clinical spectrum includes arthritis, mucocutaneous ulcers, uveitis, dermatitis, irritable bowel disease, recurrent infections, lymphopenia, hypogammaglobulinemia, recurrent fevers, and susceptibility to neoplasia. The patients represent 36 kindreds with 28 unique RELA variants, of which 15 are missense, 7 nonsense, and 6 frameshift variants. Fifteen are in the Rel homology domain, 7 in the transcriptional activation domain, and 6 in the C-terminal region proximal to TAD (Fig. 1). Functional studies assessed the canonical NFκB pathway in 27% of the cohort (n = 11; healthy controls = 40). Patient peripheral blood mononuclear cells (PBMCs) were used to quantify total and phosphorylated p65 (ph-p65, Ser529) by flow cytometry after stimulation with PMA (100 ng/ml) and ionomycin (1 uM). In 8 patients, we assessed the kinetics of IκBα degradation, required for p65 phosphorylation and nuclear translocation of p65/p50. All patients tested had decreased total p65, while 64% had decreased ph-p65 with altered phosphorylation kinetics. Nearly 45% had impaired IκBα degradation. One patient (P4) demonstrated increased IκBα degradation and ph-p65, while a related proband (P1) had decreased ph-p65. Additionally, P4 did not have the same mucocutaneous clinical phenotype as P1 despite sharing the same RELA variant. This could reflect the effect of other genetic modifiers, epigenetic, environmental, or stochastic variations, which could lead to variable expressivity and/or incomplete penetrance. All patients appeared to have haploinsufficiency, as none had normal levels of p65. This study expands the clinical and genetic spectrum of RELA-related disease and provides mechanistic insights into the impact of these variants on p65 phosphorylation and downstream function, resulting in variable expressivity.

Abstract Spatial transcriptomics links gene expression to tissue architecture, providing a mechanistic view of cellular organization. Yet existing datasets cover few donors and miss the complexity of human disease. Experimental costs remain prohibitive, and large-scale profiling is impractically slow for population-level studies. Accurate computational methods are urgently needed. Predicting gene expression from standard histology, however, remains an open problem, as current approaches transfer poorly to unseen cohorts and diseases. Here, we present Phoenix, a (latent) flow matching generative model that infers pan-cancer spatially resolved single-cell gene expression with high accuracy. Phoenix analyzes treatment response in silico: Applied to 763 head and neck cancer patients, it identified three new spatial biomarkers that we validated across two cancers (breast cancer, n = 84; ovarian cancer, n = 157) and treatment regimens (platinum, trastuzumab). Phoenix generalizes beyond carcinomas: In a large sarcoma cohort (802 tissue microarray cores), it accurately predicted cell-type-specific signatures in held-out samples and captured chemotherapy-induced immune remodeling. Phoenix also extends across species: In a mouse model, it accurately predicted the expression of pancreatic cancer lineage markers and the mutant mKras^G12D allele in silico. In total, we evaluated Phoenix on over 10,000 patients. Our results establish virtual spatial transcriptomics as a scalable framework for studying tissue organization, therapeutic response, and disease mechanisms.

ABSTRACT Background Retrospective evaluations of multidisciplinary team (MDT) review of pancreatic cystic lesions (PCL) demonstrate improved PCL management. Endoscopic ultrasound (EUS) evaluates PCL for worrisome features; however, its influence on MDT is unclear and may be attenuated by anchoring/confirmation bias. We aimed to evaluate the impact of EUS and the overall performance of MDT evaluation of PCL. Methods Four mock MDT sessions at two institutions were presented imaging from 40 consecutive PCL cases (20 “high‐risk” with advanced neoplasia, 20 “low‐risk” with pathologic low‐grade dysplasia or ≥ 3 years of non‐progression on surveillance), with and without upfront EUS/FNA (cytology, CEA, Amylase), in a randomized, crossover design. Group 1 adjudicated without EUS, Group 2 adjudicated with EUS, and Group 3 adjudicated with EUS after initially adjudicating without it. Results The cohort included branch‐duct ( n = 20), mixed type ( n = 6), and main duct ( n = 4) IPMN, MCN ( n = 5), and non‐mucinous PCL ( n = 5). Group 2 (EUS) correctly identified mucinous PCL with 97% sensitivity and 70% specificity, significantly higher than Group 1 (No EUS) (Sensitivity 91%, Specificity 20%; p = 0.04). Group 3 (Unblinded to EUS) performed significantly worse in mucinous PCL identification compared with Group 2, indicating cognitive bias (Sensitivity 97%, Specificity 10% ( p = 0.0003)). Group 2 correctly identified high‐risk PCL that required surgical intervention with 85% sensitivity and 85% specificity, significantly higher than Group 1 (Sensitivity 60%, Specificity 75%; p = 0.0016) and Group 3 (Sensitivity 73%, Specificity 80%, p = 0.0485). Conclusion While susceptible to cognitive bias, EUS significantly improves MDT assessment of PCL. MDT establishes a high bar for iterative additions of biomarkers to PCL analysis.

Abstract Solitary bone plasmacytoma (SBP) and SBP with minimal marrow involvement (SBPmm) are treated similarly with definitive radiation therapy (RT) followed by observation. However, differences in the natural disease course after RT between the two, are not well described. We performed a multicenter study assessing outcomes after RT in 141 patients with SBP and 102 with SBPmm diagnosed between January 2010 and December 2024. About 92% of patients with SBPmm progressed to multiple myeloma (MM) vs 76% of those with SBP (P = .01). Among patients with SBP, 21% progressed with a second solitary bone lesion vs 4% with SBPmm (P< .01). Patients with longer time to progression (TTP) after initial RT could achieve durable responses with RT to a second solitary plasmacytoma in the absence of other myeloma-defining events (MDE). Multifocal lytic bone lesions were the most common MDE, occurring in 89% and 81% of patients with SBPmm and SBP, respectively. Patients with SBPmm had a median TTP of 15 months (95% confidence interval [CI], 14-21) compared to 43 months (95% CI, 34-55) for those with SBP (P< .0001); 67% with SBPmm progressed within 2 years of diagnosis. Del(17p) and 1q+ (gain or amplification) were associated with shorter TTP to MM in SBPmm, with 2-year progression rates of 100% and 82%, respectively. We report significant differences in risk and modes of progression between SBP and SBPmm. Patients with SBPmm are at particularly high risk for early progression to MM, with most developing bone disease as the MDE. These findings support prospective studies incorporating frontline systemic therapy for SBPmm.

Importance Prepregnancy care and counseling optimize maternal health before conception to improve outcomes for mothers and infants. In the US, 66.4% of reproductive-aged women have at least 1 modifiable risk factor for adverse pregnancy outcomes. Observations For all individuals desiring pregnancy, recommended interventions include folic acid supplementation; cessation of tobacco, alcohol, cannabis, and opioids; immunizations against hepatitis B virus, varicella, and rubella; and screening for syphilis and HIV. Folic acid use before pregnancy is associated with reduced fetal neural tube defects (relative risk [RR], 0.67; 95% CI, 0.52-0.87). Maternal tobacco smoking is associated with increased risks of stillbirth (summary RR [sRR], 1.46; 95% CI, 1.38-1.54), neonatal death (sRR, 1.22; 95% CI, 1.14-1.30), and perinatal death (sRR, 1.33; 95% CI, 1.25-1.41). Screening for and treatment of syphilis and HIV prior to and during pregnancy decrease rates of fetal and neonatal infection. Prepregnancy immunizations against hepatitis B virus, varicella, and rubella decrease neonatal infection and mortality. Individuals using tobacco, alcohol, cannabis, and opioids should receive counseling and treatment prior to pregnancy (eg, buprenorphine or methadone for opioid use disorder). For individuals with chronic disease, routine health examinations and contraceptive care in the year before conception can optimize pregnancy timing and are associated with decreased risk of severe maternal morbidity. Compared with planned pregnancies, unintended pregnancies are associated with increased risk of postpartum depression (15.7% vs 9.6%; adjusted odds ratio [aOR], 1.51; 95% CI, 1.40-1.70), preterm birth (9.4% vs 7.7%; aOR, 1.21; 95% CI, 1.12-1.31), and low infant birth weight (7.3% vs 5.2%; aOR, 1.09; 95% CI, 1.02-1.21). Weight loss prior to conception is recommended for individuals with a body mass index of 25 or greater because overweight and obesity are associated with increased risk of gestational diabetes, gestational hypertension, and cesarean delivery. Among patients with pregestational diabetes (type 1 or 2), hemoglobin A 1c of less than 6.5% is associated with a decreased risk of fetal anomaly compared with hemoglobin A 1c of 6.5% or greater. Cardiovascular complications such as hypertension and heart failure occur in 15% of pregnancies and are more common among those with preexisting cardiovascular disease. These patients should receive counseling on maternal and neonatal risk, monitoring, and medication management by specialists in cardiology and maternal fetal medicine. Conclusions and Relevance Prepregnancy counseling and care reduce maternal morbidity and neonatal morbidity and mortality. Primary care–based discussion of reproductive goals, immunizations, screening for infections and substance use, and risk-reducing interventions such as folate supplementation can optimize outcomes in individuals contemplating pregnancy.

Purpose: During diagnostic cerebral angiography, catheter navigation requires manual contrast “puff” injections, while subsequent 2D/3D runs often use automated power injectors. Using power injectors for navigation puffs has not been described. We present a closed-circuit dual-port injector system (Nemoto Press Duo Elite) that integrates both navigation puff delivery and diagnostic run injection into a single automated platform, eliminating all manual tableside contrast handling. A foot pedal interface enables operator-controlled puff timing, potentially reducing contrast waste and air embolism risk while improving single-operator ergonomics with future remote robotic implications.Materials and Methods: This retrospective comparative cohort study compared 19 consecutive patients undergoing diagnostic cerebral angiography with foot pedal-controlled puff injections (June–July 2023) to 19 historical controls using manual hand injections (May 2021). Both groups used 90% contrast concentration. Fluoroscopy time, radiation dose, contrast utilization, and safety outcomes were compared.Results: Groups were demographically matched (mean age 52.1±14.2 vs. 50.2±12.9 years; 73.7% female). All 38 procedures achieved diagnostic adequacy with no complications. The foot pedal group demonstrated significantly shorter procedure time per vessel (11.5±4.4 vs. 18.9±10.5 min/vessel, P=0.010) with no significant differences in fluoroscopy time (P=0.171), radiation dose (P=0.690), or contrast delivered (88.7±30.9 vs. 88.2±42.5 mL, P=0.966). A trend toward improved contrast efficiency was observed (23.4±9.4 vs. 27.4±10.4 mL/vessel, P=0.226). Despite undergoing significantly more 3D rotational runs (1.3±1.0 vs. 0.6±0.7, P=0.030), the foot pedal group maintained comparable safety metrics, strengthening the non-inferiority findings.Conclusion: A closed-circuit dual-port injector system integrating automated navigation puff delivery with diagnostic run injection demonstrates non-inferiority to manual injection for diagnostic cerebral angiography, with shorter procedure time per vessel (39% reduction, P=0.010), though interpretation is limited by differences in indication distribution. By eliminating manual tableside contrast handling, this approach enables precise digital contrast accounting and reduces air embolism risk, establishing a foundation for remote and robotic angiography applications.

Abstract Background: Zedoresertib (zedo) and lunresertib (lunre) are oral, highly selective WEE1 and PKMYT1 inhibitors, respectively. Inhibition of these targets leads to premature mitotic entry, and in the presence of high replication stress causes mitotic catastrophe. In preclinical models, the combination of the zedo and lunre is synthetically lethal, supporting this first-in-class trial combination (NCT04855656). Methods: In this Phase 1 trial, patients (pts) with advanced solid tumors with CCNE1 amplification (amp), or FBXW7 or PPP2R1A deleterious mutations (mut) were treated with zedo (daily dosing) plus lunre (3 days on/4 days off), guided by preclinical modelling of the pharmacological contributions of WEE1 and PKMYT1 inhibition in achieving tumor regression. Objectives included safety, tolerability, recommended doses (RD), pharmacokinetics (PK), pharmacodynamics (PDy), antitumor activity and molecular response rate (MRR; ≥50% decline in circulating tumor DNA). Results: As of 18 Nov 2025, 54 pts (55.6% female ; prior lines of therapy 1 - 9, main cancer types: ovarian (OC) (35.2%), colorectal (31.5%), pancreatic (7.4%) and breast (5.6%)) were treated at 5 dose levels (DL) from 150 mg to 260 mg of zedo plus 60 mg or 80 mg of lunre. The most common ≥G3 treatment related adverse events (TRAEs) were anemia (9.3%), neutropenia (7.4%) and Palmar Plantar Erythrodysesthesia (PPE) (7.4%). There were no G5 TRAEs. 4 (9.3%) of 54 pts had a dose-limiting toxicity (G3 pain in extremity and G1 rash in same pt (zedo 150 mg / lunre 60 mg), G3 rash (200 mg / 80 mg), G3 PPE (260 mg / 60 mg), G3 vomiting (260 mg / 60 mg)). PK/PDy analyses showed dose-dependent exposures for both zedo and lunre and target engagement in most pts, with reductions in pCDK1 Thr14 and Tyr15 and yH2AX induction. 24 (55.5%) of 44 RECIST v1.1 evaluable pts showed tumor shrinkage (3 cCR, 5 uPR, 15 SD and 1 PD). Of 16 evaluable pts with advanced OC (12 platinum resistant , 2 unknown and 2 platinum sensitive) with CCNE1 amp (13 pts) or FBXW7 mut (3 pts), 13 (81.3%) showed tumor shrinkage (3 cCR, 3 uPR and 7 SD); clinical benefit rate (pts with CR, PR or SD) was 93.8%; 7 (43.8%) OC pts were on treatment for at least 16 weeks; 4 (25%) OC pts achieved GCIG CA-125 responses. Of 23 pts with a post baseline ctDNA analysis, a MRR of 39% was seen across all DLs. Conclusion: We report the first disclosure of clinical data of the first-in-field synthetic lethal combination of WEE1 and PKMYT1 inhibitors in a molecularly defined pt population. The safety profile of zedo and lunre was expected and manageable. Promising antitumor activity was observed in pts with CCNE1 amp or FBXW7 mut solid tumors, especially pts with OC. Further dose optimization of this combination is ongoing. Citation Format: Timothy A. Yap, Rahul Aggarwal, Elisa Fontana, Martin Hojgaard, Benedito A.
