Introduction Women residing in rural areas or belonging to lower socioeconomic status (SES) strata experience disproportionately low rates of breast cancer screening, contributing to delayed diagnoses and poorer prognoses. In addition, their participation in clinical trials remains markedly limited, reducing opportunities to access preventive and screening interventions. Promoting research preparedness among women before disease onset may empower them to make informed decisions regarding their health and willingness to participate in clinical research with fewer emotional and logistical barriers. Methods and analysis This project applies a community-based participatory research approach to develop and refine the WeCARE (Women’s Engagement for Cancer Awareness, Resources and Education) intervention for women aged 50–74 years who have either never undergone breast cancer screening or have not received screening in the past 5 years and who reside in rural areas or belong to low SES groups. The intervention consists of two components. Component 1 is a single-day, in-person community forum that includes (a) an educational seminar led by an oncologist to address breast cancer risk and screening guidelines, (b) survivor storytelling to enhance emotional engagement and cultural resonance and (c) facilitated navigation to breast cancer screening and future research participation. Component 2 involves structured post-forum follow-up through multiple touchpoints (phone calls and mailed boosters) to reinforce knowledge, address barriers and support screening completion and research enrolment. Quantitative data (eg, screening completion, satisfaction and follow-up engagement) will be summarised using descriptive statistics to assess feasibility and reach on 50 participants. Qualitative feedback from participants will undergo thematic analysis to identify barriers, facilitators and perceived cultural relevance. Integrated mixed-method interpretation will inform iterative refinement of the WeCARE intervention and guide design of subsequent larger trials. Ethics and dissemination Approved by the Mayo Clinic Institutional Review Board (IRB #25–008934). All participants will provide informed consent. Procedures ensure confidentiality, cultural sensitivity and participant safety. Data will be stored in REDCap and disseminated through publications, conferences, local town halls and community reports.

Background: EUS-guided gastroenterostomy (EUS-GE) is an effective option for the management of gastric outlet obstruction (GOO). Due to the poor prognosis of patients undergoing it, data on its long-term adverse events (AE) is scarce. Herein, we describe a cohort of patients with gastro-entero-colic fistula (GECF) as a late AE of previously successful EUS-GE. Methods: Patients who developed a GECF after EUS-GE from 10 high-volume centers were analyzed. Information collected included demographic characteristics, indications, clinical and technical success rates, stent type and size, fistula characteristics, management, and outcomes. Results: Sixteen cases were identified. The mean interval from index EUS-GE to the diagnosis of GECF was 4 to 8 weeks. The most common cause of GOO was pancreatic adenocarcinoma (PDAC). The transverse colon was the most common site for the GECF (14 patients). A 20×10 mm lumen apposing metal stent (LAMS) was utilized in 10 patients. Endoscopic management with a variety of modalities was successful in 13 cases. Follow-up interval after endoscopic management of the fistula averaged 2 to 4 weeks. At the time of the manuscript elaboration, 10 patients had died, 5 were alive, and 1 was lost to follow-up. Conclusions: This is the first description of a cohort of patients with GECF after EUS-GE. The exact mechanisms leading to GECF in these cases are unknown. Possible explanations include inadvertent colon puncture during the index procedure and/or entrapment of mesocolon. More data is needed to further characterize this AE.

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.

Modulating immune function is a critical strategy in cancer and atherosclerosis treatments. For cancer, boosting or maintaining the immune system is crucial to prevent tumor growth. However, in vascular disease, mitigating immune responses can decrease inflammation and slow atherosclerosis progression. Anti-inflammatory therapy, therefore, presents a unique dilemma for cancer survivors: while it may decrease cardiovascular risk, it might also promote cancer growth and metastasis by suppressing the immune response. Senescence presents a potentially targetable solution to this challenge; senescence increases the risk of both cancer therapy resistance and vascular disease. Exercise, notably, shows promise in delaying this premature senescence, potentially improving cancer outcomes and lowering vascular disease risk post-treatment. This review focuses on the long-term impact of cancer therapies on vascular health. We underscore the importance of modulating senescence to balance cancer treatment’s effectiveness and its vascular impact, and we emphasize investigating the role of exercise-mediated suppression of senescence in improving cancer survivorship.

Abstract Background The recognition of autoimmune causes of encephalitis has led to epidemiological shifts in the worldwide characteristics of encephalitis. N-methyl-D-aspartate receptor (NMDAR) antibody encephalitis leads to well-established complex neuropsychiatric manifestations. In low- and middle-income countries, including Vietnam, its relative incidence, especially in children, is unknown and most neurologists currently consider infectious encephalitis prior to autoimmune etiologies. Methods The study was prospectively conducted at Children's Hospital 1 in Ho Chi Minh City between March 2020 and December 2022. Any child admitted to the Department of Infectious Diseases and Neurology fulfilling the case definition of encephalitis was eligible to participate. Cerebrospinal fluid samples were collected alongside meta-clinical data for analysis. Results We recruited 164 children with a clinical diagnosis of encephalitis. Etiologies were determined as NMDAR antibody encephalitis in 23 of 164 cases (14.0%), Japanese encephalitis virus in 14 of 164 (8.5%), and herpes simplex virus in 4 of 164 (2.4%). Clinical categorizations suggested idiopathic viral encephalitis in another 71 (43.3%), and autoimmune encephalitis of unknown origin in the remaining 52. Factors including demographics, specific clinical features, cerebrospinal fluid and electroencephalogram findings, and length of hospital stay were significantly different between NMDAR antibody encephalitis and Japanese encephalitis. Conclusions At a tertiary children's hospital in Vietnam, the prevalence of NMDAR antibody encephalitis exceeds that of Japanese encephalitis, the most common infectious encephalitis cause in Southeast Asia. NMDAR antibody encephalitis is associated with long hospital stay and poor outcomes. These findings should change pediatric diagnostics, to earlier consider autoimmune treatments in this clinical setting.

ABSTRACT. Encephalitis is a significant global health problem, especially in children. Knowledge of its economic burden is essential for policymakers in prioritizing the development and implementation of interventions but remains limited. An observational study was prospectively conducted at a major children’s hospital in Ho Chi Minh City, Vietnam from 2020 to 2022. Data on direct medical costs, direct nonmedical costs, and productivity costs were collected alongside demographic information, clinical features, diagnosis, severity, and outcomes of study participants. This was used to undertake a cost of illness analysis from a societal perspective. Data were collected from a total of 164 pediatric patients. The median cost of illness was estimated at US $1,859 (interquartile range [IQR]: US $1,273–$3,128). The direct costs were the main cost driver, accounting for 83.9% of the total cost of illness (US $1,560; IQR: US $975–$2,460). The productivity costs accounted for a median of US $275 (IQR: US $154–$474). The cost of illness was higher in more severe patients, patients with sequelae, patients with morbidities, and ventilated patients. Most direct medical costs were attributed to hospitalization and resulted in out-of-pocket payments from the patient’s family (30.2%; US $316). The results showed that the cost of illness of encephalitis in children is considerable and will be useful for policymakers in prioritizing resources for the development and implementation of intervention strategies to reduce the burden of pediatric encephalitis.

Background: D-flow’s impact on metabolic reprogramming, particularly glycolysis, needs reevaluation due to its conflicting role in atherosclerosis. We show that d-flow reduces LATS1/2 expression, leading to both EC proliferation and senescence. However, the exact molecular mechanisms remain elusive. Methods: We utilized EC-specific Lats1 +/- /Lats2 -/- knockout (LATS1/2-EKO) mice in a partial left carotid ligation (PLCL) model under hypercholesterolemia with AAV-PCSK9 injection to mimic d-flow. Anti-CD38 antibody (Ab68) and IgG2a control were administered intraperitoneally every 5 days at a dose of 5 mg/kg starting one day before PLCL. Plaque characterization was performed using imaging mass cytometry and sequential immunofluorescence (COMET TM ), integrating spatial metabolite data from Bruker timsTOF Flex Mass Spectrometer, and spatial single-cell metabolite data via the Visiopharm platform. Results: EC LATS1/2 depletion induced a unique atherothrombosis lesion with induced EC proliferation and senescence-associated secretory phenotype (SASP). Utilizing spatial single-cell metabolomics, we cataloged 134 distinct metabolites within the ECs. Subsequent overrepresentation analysis revealed that pathways related to glutamate and the citric acid cycle were enhanced in LATS1/2-EKO mice. Specifically, CD38-dependent downregulation of the pyruvate dehydrogenase (PDH) substrate lipoamide decreased PDH enzymatic activity, linking to CD38 to senescence induction. This inhibition led to a metabolic shift towards YAP-dependent glutaminolysis, and upregulated the citric acid cycle. The use of a glutaminase 1 inhibitor (CB-839) significantly curtailed senescence-associated stemness (SAS), underscoring the pivotal role of CD38 in driving glutaminolysis that contributes to d-flow-induced SAS. Moreover, the application of Ab68 but not IgG2a control decreased atherothrombosis formation following PLCL in LATS1/2-EKO mice. However, the effectiveness of Ab68 in attenuating atherosclerosis in wild-type mice was less pronounced. Conclusions: In the presence of d-flow, upregulated CD38, resulting from reduced LATS1/2 expression, triggers EC responses characterized by increased glutaminolysis and the emergence of an EC SAS phenotype. These processes play a crucial role in a unique form of atherothrombosis. Additionally, CD38’s impact on reducing PDH activity, along with YAP and CD38-mediated enhancement of glutaminolysis, constitutes critical pathways for inducing EC SAS by d-flow.

Background: Atherosclerotic plaques, especially high-risk ones, form in blood vessel regions exposed to d-flow. EC dysfunction induced by d-flow likely contributes to plaque development. In contrast, regions with laminar flow (l-flow) are less susceptible to plaque formation. Although the Hippo pathway is implicated in mechano-transduction, the exact role and molecular mechanisms of LATS1/2 in response to d-flow remain incompletely understood. Methods: We employed endothelial cell (EC)-specific Lats1 and Lats2 knockout mice within a partial left carotid ligation (PLCL) model to simulate disturbed flow conditions. We characterized plaques using imaging mass cytometry (IMC) and sequential immunofluorescence via COMET TM . Results: We investigated the effects of d-flow on YAP activity and LATS1/2 expression. While both l-flow and d-flow activate YAP activity, only d-flow leads to decreased LATS1/2 expression. We induced Lats1/2 deletion in tamoxifen-inducible Lats1 -/- /Lats2 -/- EKO mice. Within 14 days, all mice (27/27) died due to severe systemic edema and increased vascular permeability. In Lats1 +/- /Lats2 -/- EKO mice (LATS1/2-EKO), we observed atherothrombotic lesions characterized by increased EC proliferation and a senescence-associated secretory phenotype (SASP) in vivo . Mechanistically, d-flow reduces LATS1/2 expression, leading to increased CD38 expression. CD38 triggers not only SASP, but also senescence-associated stemness (SAS) via NAD + depletion, dependent on Lamin A but independent of YAP. We also explored the relationship between CD38 and Ki67 in plaques in vivo. We calculated the logarithm of the Ki67:CD38 expression ratio at the single-cell level using IMC/COMET data. Based on the trimodal density distribution of this parameter, we found that in one group, CD38 and Ki67 were linearly co-expressed, and the percentage of LATS1/2-depleted cells in this group exceeded that of wild type (WT) cells, suggesting that CD38’s pro-proliferative effects dominate under LATS1/2 depletion conditions, despite its role in inducing senescence. Lastly, inhibiting CD38 mitigated d EC SAS/SASP, and atherothrombosis under LATS1/2 depletion conditions. Conclusions: Reduced LATS1/2-mediated CD38 expression in response to d-flow leads to an EC response marked by increased SASP/SAS, ultimately contributing to atherothrombosis. While this phenomenon is common in human advanced coronary atherosclerosis, it is not observed in commonly used mouse models of atherosclerosis.

Abstract VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome, caused by somatic mutations in UBA1, is an autoinflammatory disorder with diverse systemic manifestations. Thrombosis is a prominent clinical feature of VEXAS syndrome. The risk factors and frequency of thrombosis in VEXAS syndrome are not well described, due to the disease’s recent discovery and the paucity of large databases. We evaluated 119 patients with VEXAS syndrome for venous and arterial thrombosis and correlated their presence with clinical outcomes and survival. Thrombosis occurred in 49% of patients, mostly venous thromboembolism (VTE; 41%). Almost two-thirds of VTEs were unprovoked, 41% were recurrent, and 20% occurred despite anticoagulation. The cumulative incidence of VTE was 17% at 1 year from symptom onset and 40% by 5 years. Cardiac and pulmonary inflammatory manifestations were associated with time to VTE. M41L was positively associated specifically with pulmonary embolism by univariate (odds ratio [OR]: 4.58, confidence interval [CI] 1.28-16.21, P = .02) and multivariate (OR: 16.94, CI 1.99-144.3, P = .01) logistic regression. The cumulative incidence of arterial thrombosis was 6% at 1 year and 11% at 5 years. The overall survival of the entire patient cohort at median follow-up time of 4.8 years was 88%, and there was no difference in survival between patients with or without thrombosis (P = .8). Patients with VEXAS syndrome are at high risk of VTE; thromboprophylaxis should administered be in high-risk settings unless strongly contraindicated.
