ABSTRACT Disease Overview POEMS syndrome is a life‐threatening syndrome due to an underlying plasma cell neoplasm. The major criteria for the syndrome are polyneuropathy, clonal plasma cell disorder (PCD), sclerotic bone lesions, elevated vascular endothelial growth factor, and the presence of Castleman disease. Minor features include organomegaly, endocrinopathy, characteristic skin changes, papilledema, extravascular volume overload, and thrombocytosis. Diagnosis The diagnosis of POEMS syndrome is made with three of the major criteria, two of which must include polyneuropathy and clonal plasma cell disorder, and at least one of the minor criteria. Risk Stratification Because the pathogenesis of the syndrome is not well understood, risk stratification is limited to clinical phenotype rather than specific molecular markers. Risk factors include low serum albumin, age, pleural effusion, pulmonary hypertension, and reduced eGFR. Risk‐Adapted Therapy For those patients with a dominant plasmacytoma, first line therapy is irradiation. Patients with diffuse sclerotic lesions or disseminated bone marrow involvement should receive systemic therapy. Corticosteroids are temporizing, but alkylators and lenalidomide are the mainstays of treatment, the former either in the form of low dose conventional therapy or as high‐dose conditioning for stem cell transplantation. Thalidomide and bortezomib also have activity, but their benefit needs to be weighed against their risk of exacerbating the peripheral neuropathy. Daratumumab combinations also appear promising based on case series. Prompt recognition and institution of both supportive care measures and therapy directed against the plasma cell result in the best outcomes.

Background: Patients with spontaneous coronary artery dissection (SCAD) are at increased risk of cardiovascular events, including dissection in other arterial territories such as cervical arteries. Those with combined coronary and cervical arterial dissection (CACAD) may have more widespread arterial abnormalities and worse outcomes, underscoring the need for better risk stratification and personalized care. Objective: This study examined the prevalence of cervical artery dissection (CvAD) in patients diagnosed with SCAD, evaluated potential risk factors for developing CvAD, and assessed their impact on clinical outcomes, including all-cause mortality, SCAD recurrence, and stroke. The goal was to enhance risk stratification by identifying SCAD patients at increased risk for CvAD. Design: In this retrospective cohort study, patients diagnosed with SCAD between 2018 and 2024 across Mayo Clinic sites were identified using ICD-10 codes. Manual chart review confirmed CvAD diagnoses. Patients were stratified based on the presence or absence of CvAD. Chi-square and independent t-tests were used to compare risk factors and comorbidities. Univariate screening and multivariable logistic regression were used to identify predictors of CvAD. Results: Among 1380 patients with SCAD, 131 (9.5%) had CvAD. The median follow-up was 2.02 years (IQR: 1.1–5.2 years). All CvAD diagnoses were identified after the index SCAD event through systematic post-SCAD vascular imaging. The mean age was similar between groups (51.5 ± 11.3 years in CACAD vs. 50.9 ± 10.7 years in SCAD-only, p = 0.540), and the majority were female (93.9% vs. 91.9%, p = 0.529). Multivariable regression identified extremity arterial dissection (OR: 8.13, 95% CI: 3.41–19.36, p < 0.001), fibromuscular dysplasia (FMD) (OR: 7.52, 95% CI: 4.67–12.10, p < 0.001), connective tissue disorders (CTDs) (OR: 6.85, 95% CI: 2.35–19.98, p < 0.001), and anxiety (OR: 1.69, 95% CI: 1.01–2.81, p = 0.044) as significant predictors of CvAD. CvAD was a strong independent predictor of stroke (OR: 6.37, 95% CI: 2.93–13.87, p < 0.001). Mortality and SCAD recurrence did not differ significantly between groups. Conclusions: Patients with CACAD demonstrate a systemic vascular phenotype with significantly higher rates of FMD, connective tissue disease, extremity arterial dissection, and stroke. These findings highlight the importance of comprehensive vascular screening and individualized monitoring in at-risk SCAD patients.

ABSTRACT Background Artificial intelligence (AI) and automation offer opportunities to enhance the efficiency, timeliness, and sustainability of living guidelines (LGs). However, how AI and automation have been integrated into existing LG development frameworks remains unclear. This scoping review represents the first step in a broader programme of work aimed at developing a framework which aims to guide responsible and coordinated AI adoption across all phases of LG development. Objective To identify existing frameworks, methods, and approaches that integrate AI or automation into any stage of LG development. Methods We conducted a structured search of PubMed, Embase, Web of Science, Scopus, Cochrane Database for Systematic Review and Cochrane Central Register of Controlled Trials from inception to March 12, 2026. We included peer‐reviewed articles describing frameworks, models, or methods that applied AI or automation in the development of LGs. We extracted data into a standardised form, capturing study characteristics, AI methods, targeted guideline processes, and key findings and synthesised findings using a thematic narrative approach. Results Of 1090 records identified, three studies met the inclusion criteria. The included studies described AI or automation applied to select components of the LG process, to support continuous evidence surveillance, to semi‐automate study screening, and incremental updating of living systematic reviews. None addressed multiple stages of LG development in an integrated manner. Conclusions Current evidence demonstrates fragmented and narrowly focused AI or automation applications within LG development processes. Our findings highlight opportunities for future work to develop and evaluate more comprehensive frameworks that span multiple stages of the LG lifecycle.

ABSTRACT Clinical pharmacists are increasingly recognized as vital contributors to acute stroke care, yet their role remains inconsistently defined and underutilized across health care systems. This consensus statement explores the expanding presence of clinical pharmacists within interdisciplinary stroke teams, particularly in the management of both acute ischemic stroke ( AIS ) and hemorrhagic stroke. This consensus statement panel was composed of clinical pharmacists, emergency medicine physicians, and a vascular neurologist. The Grading of Recommendations, Assessment, Development, and Evaluation ( GRADE ) approach was used to assess the level of certainty and strength of recommendations. We focused on two questions regarding the clinical pharmacist's role in caring for adult patients presenting to the emergency department ( ED ) with AIS or hemorrhagic stroke. Despite the very low level of evidence, a consensus was reached for the following recommendations: (1) clinical pharmacist involvement in AIS care for adult patients presenting to the ED and (2) clinical pharmacist involvement in hemorrhagic stroke care for adult patients presenting to the ED . Based on the available literature, we believe optimizing the clinical pharmacist role is a critical factor in improving time‐sensitive treatment and equity in care delivery.

Abstract INTRODUCTION We integrate visual and quantitative metrics in white matter and medial temporal lobe to examine relationships with neuropathology in a community cohort. METHODS Postmortem in situ MRI (T1, T2, DWI) was performed in 25 human brains, followed by visual ratings (Fazekas, MTA, ERICA, Koedam). Neuropathology included ADNC, LATE-NC, hippocampal sclerosis, PART, ARTAG, Lewy pathology, and CAA. RESULTS Increased Fazekas score was linked to aging, lower education, hypertension, higher basilar artery wall thickness, and greater Braak NFT stage. WMH volume also correlated with lacunes, Thal phase, and CERAD score that was not observed using Fazekas. Hippocampal volumes were lower in elderly, less educated people and were associated with higher atrophy scores and higher Braak NFT stage. Higher amygdala volume was only associated with higher CERAD score. DISCUSSION Quantitative MRI may detect neuropathologic associations more sensitively than visual ratings. Tau pathology is a key predictor of WMH burden and hippocampal atrophy.

Penile squamous cell carcinoma (PSCC) is a rare malignancy with limited therapeutic options in advanced and recurrent diseases. Advanced PSCC is typically managed with multimodal therapy, including neoadjuvant chemotherapy or chemoradiation followed by surgery; however, durable responses remain uncommon, and outcomes after recurrence are poor. Cancer vaccines represent a promising immunotherapeutic strategy, as these treatments induce tumor-specific immunity and heightened immune surveillance against penile cancer cells. While therapeutic cancer vaccines have not yet demonstrated consistent clinical efficacy as monotherapy in PSCC, their integration with complementary immune-modulating approaches, particularly immune checkpoint blockade, represents a rational strategy to enhance antitumor immunity. This review summarizes the rationale for vaccine development in PSCC, with emphasis on HPV-derived antigens, neoantigens, and emerging tumor-associated targets. We examine major vaccine platforms, including viral-vector, peptide-based, nucleic acid, and dendritic cell-based approaches. We also discuss how spatial transcriptomics, single-cell RNA sequencing, artificial intelligence-assisted antigen prediction, and nanotechnology-enhanced delivery systems may support future personalized vaccine development. Overall, therapeutic vaccines remain investigational in PSCC but may become relevant within biomarker-driven, combination-based immunotherapy strategies.
