Abstract Background Diabetes mellitus elevates Parkinson’s disease (PD) risk, via hypothesized cerebrovascular mediation. Whether the diabetes/prediabetes vascular-risk phenotype concentrates in cardiometabolic risk or macrovascular events across prodromal and clinically diagnosed PD remains unresolved. Objectives To quantify the vascular-risk burden associated with diabetes/prediabetes across the PPMI diagnostic cohorts to test whether this association differs by cohort. Methods Cross-sectional analysis of 413 PPMI participants (76 healthy controls, 145 prodromal PD, 192 clinically diagnosed PD) examined diabetes/prediabetes (n = 73) and seven vascular risk factors. The Vascular Burden Score (0 to 7) was a priori partitioned into microvascular and macrovascular sub-scores. Modified Poisson regression estimated adjusted prevalence ratios (aPR), adjusted for age, sex, and body mass index. A cohort-by-diabetes interaction tested cross-cohort consistency. Sensitivity analyses incorporated nigral diffusion tensor imaging (PD-risk biomarker) and FreeSurfer white matter hypointensity volume (cerebrovascular marker). Results Diabetes/prediabetes elevated Vascular Burden Score (β = 0.53, 95% CI 0.29 to 0.77, p < 0.001) versus non-diabetic participants, with a non-significant cohort-by-diabetes interaction (F = 0.29, p = 0.747). Three microvascular factors survived false discovery rate correction: obesity (aPR 2.28), hypertension (aPR 1.60), and hyperlipidemia (aPR 1.45). Macrovascular events showed no diabetic amplification (β = −0.06, p = 0.25). In the imaging-phenotyped subset, Vascular Burden Score components contributed classifier variance distinct from nigral microstructure. Conclusions Diabetes/prediabetes operationalize a microvascular cluster stable across prodromal and idiopathic PD. Cardiometabolic phenotyping may complement established PD-risk biomarkers (dopamine transporter SPECT, nigral diffusion), pending longitudinal validation linking vascular phenotype to dopaminergic markers.

Background The optimal imaging guidance for percutaneous coronary intervention (PCI) in complex coronary lesions remains a matter of debate. This meta-analysis compares the efficacy and safety of optical coherence tomography (OCT)-guided PCI versus angiography-guided PCI. Methods Following PRISMA guidelines, we systematically searched PubMed, Embase, Cochrane, and ClinicalTrials.gov from inception to December 2024. Randomized controlled trials (RCTs) comparing OCT-guided PCI to angiography-guided PCI were included. Data analysis was performed using RevMan 5.4, with risk ratios (RR) and 95% confidence intervals (CI) calculated for dichotomous outcomes using a random-effects model. Risk of bias was assessed using the Cochrane RoB 2.0 tool. Results Eleven RCTs involving 6432 participants were included. OCT-guided PCI showed no statistically significant reduction in all-cause mortality compared to angiography-guided PCI (RR 0.72, 95% CI 0.51–1.01, P = 0.06, I 2 = 0%). However, OCT-guided PCI was associated with a significant reduction in cardiac death (RR 0.52, 95% CI 0.30–0.90, P = 0.02, I 2 = 0%), major adverse cardiovascular events (MACE) (RR 0.70, 95% CI 0.55–0.89, P = 0.003, I 2 = 0%), stent thrombosis (RR 0.53, 95% CI 0.33–0.87, P = 0.01, I 2 = 0%), and major edge dissection (RR 0.47, 95% CI 0.34–0.65, P < 0.00001, I 2 = 0%). Upon stratification of studies on the basis of follow-up duration, similar results were noted. Conclusion OCT-guided PCI demonstrated significant benefits in reducing cardiac death, MACE, and procedural complications compared to angiography-guided PCI. These findings support the integration of OCT in complex PCI, although further studies are warranted to assess its impact on long-term mortality.

ABSTRACT Inpatient, acute care clinical pharmacists have contributed to many notable improvements in patient outcomes. Several studies have shown a reduction in mortality and other clinical markers when pharmacists are integrated within the care team. Economic analyses of inpatient clinical pharmacy services (CPS) generally demonstrate cost savings related to specific medication classes, prevention of adverse drug events, decreased length of stay, and decreased rehospitalization. Studies also show high satisfaction from other health care professionals, noting improvements in medication‐related patient safety. Finally, studies conducted in tertiary care hospital settings report high levels of patient satisfaction with CPS. As such, the ECHO framework, based on economic, clinical, and humanistic outcomes, is used herein to organize the summary of literature associated with CPS. Given the growing body of evidence, numerous health professional and government organizations recognize the role of pharmacists as an integral part of the inpatient team. Yet implementation of CPS has not been fully realized by hospitals and health systems. This paper briefly describes inpatient CPS, highlights many benefits of and endorsements for clinical pharmacist participation on interdisciplinary teams, and provides high‐level recommendations for health system administrators and the profession of pharmacy to further encourage broader integration of CPS into patient care teams. Effectively positioning inpatient clinical pharmacists as indispensable team members will require intentional work and strategic planning with a focus on high‐impact value, visibility, and leadership.

Abstract Exposure to asbestos is the primary cause of mesothelioma, however the processes underpinning its initiation and evolutionary trajectory remain elusive. To address this knowledge gap, we conducted whole exome sequencing and phylogenetic analysis of 277 mesotheliomas. Using multidimensional Dirichlet process clustering we inferred phylogenies, uncovering mutation order dominated by early 13q,1p, 8p, 6q and 22q somatic copy number alterations. Mesotheliomas exhibit a spectrum of genomic intra-tumor heterogeneity spanning linear (L) to highly branched (B) tree topologies, quantifiable by the Weighted Shannon Entropy (WSE). Somatic copy number alterations emerge earlier than single nucleotide variants (SNVs), and at a much faster relative rate in L-mesotheliomas. BAP1 is the only positively selected driver in L-mesotheliomas, whereas, B-mesotheliomas harbor multiple positively selected drivers and an aggressive phenotype, including a bias of loss of RPL5, and MTAP deletion linked to breakpoint enriched with long interspersed nuclear elements. L-trees had lower WSE, but greater T-cell inflammation and tertiary lymphoid structures, despite having a lower neoantigen burden. WSE is higher in larger volume, immunologically cold mesotheliomas, and is associated with shorter survival. In summary, progressive genomic heterogeneity is a defining feature of more aggressive mesothelioma yet illuminates opportunities for precision therapeutic intervention.

Purpose: Neuroendocrine neoplasms (NENs) are increasingly recognized to have a hereditary predilection, yet the prevalence and clinical relevance of pathogenic germline variants (PGVs) in unselected patients with NEN remain poorly defined. This prospective, multicenter study aimed to evaluate the prevalence and clinical utility of PGVs through universal multigene panel testing in a diverse cohort of patients with NENs. Patients and Methods: Between 2018 and 2024, we enrolled unselected patients with NENs from 3 Mayo Clinic Cancer Centers. Germline genetic testing was performed using a next-generation sequencing panel of up to 84 cancer predisposition genes. Patients were not selected based on age, disease stage, ethnicity, or family history. Variants were classified as PGVs, variants of uncertain significance (VUS), or negative. Clinical and demographic data were analyzed descriptively. Results: Among 88 patients, PGVs were identified in 15.9% (n=14), most frequently in high- or moderate-penetrance genes including MEN1 , CHEK2 , MITF , and MUTYH . PGVs were most commonly found in pancreatic NENs [n=12/55 (21.8%)], followed by small bowel NENs [n=2/20 (10%)], with no PGVs detected in lung NENs. Mismatch repair (MMR) gene alterations were identified in 5.7% of patients, including 1 MLH1 PGV and 4 MSH2/MSH6 VUS, 2 of which demonstrated MMR deficiency by protein testing. VUS were reported in 34.1% of patients. Notably, 35.7% of PGV-positive patients did not meet current NCCN or ACMG testing criteria, and 53.9% had PGVs in genes outside of cancer-specific guideline recommendations. Conclusions: Universal germline testing in unselected patients with NEN identified clinically relevant PGVs in over 15% of cases. These findings support broader genetic testing approaches to guide treatment, enhance familial risk assessment, and inform cascade testing—regardless of traditional clinical selection criteria.

ABSTRACT Background : Tirofiban is a GP IIb/IIIa inhibitor, an anti‐platelet drug that is used in ischemic stroke or acute coronary syndromes. The goal of this study is to assess the safety and efficacy of the drug in patients who have suffered an acute ischemic stroke. Methods : A comprehensive search of PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov from inception to December 2025 yielded randomized controlled trials (RCTs) comparing Tirofiban and conventional management in patients with acute ischemic stroke. We assessed the risk of bias using the revised Cochrane “Risk of bias” tool for randomized trials (RoB 2.0). We analyzed the outcomes using RevMan 5.4, with risk ratio (RR) as the effect measure. Results : A total of 9 RCTs with 4210 patients were included in our meta‐analysis. According to our meta‐analysis, the tirofiban group was associated with a statistically significant increase in the patients showing functional independence at 90 days, measured by patients with Modified Rankin Score (mRS) of 0–2 (RR 1.13; CI = 1.06–1.20) and excellent outcome (mRS score 0–1) at 90 days (RR 1.17; CI = 1.05–1.29). We found no statistically significant difference between the two groups regarding mortality (RR 0.94; CI = 0.63–1.40). The tirofiban group had an increased incidence of intracranial hemorrhage (ICH) (RR 1.25; CI = 1.06–1.47) but had a similar incidence of symptomatic ICH as compared to the control group (RR 1.48; CI = 0.98–2.24). Conclusion : This meta‐analysis suggests that tirofiban may improve favorable functional outcomes (mRS 0–2) in acute ischemic stroke, although the certainty of evidence was moderate. While no significant increase in sICH was observed, some analyses showed a higher rate of overall intracranial hemorrhage. These findings should therefore be interpreted cautiously, and further high‐quality randomized trials are needed to confirm the efficacy and safety of tirofiban before routine guideline use.

PURPOSE In immunoglobulin light chain (AL) amyloidosis, amyloid fibrils cause organ dysfunction. Anselamimab, a monoclonal antibody, selectively binds to amyloid fibrils, accelerating their clearance. METHODS Newly diagnosed patients with European modification of Mayo 2004 stage IIIa or IIIb AL amyloidosis were randomly assigned to receive anselamimab or placebo with cyclophosphamide, bortezomib, and dexamethasone (with or without daratumumab). The primary end point was a hierarchical composite of time to all-cause mortality (ACM) and frequency of cardiovascular hospitalizations (CVHs), analyzed using the Finkelstein-Schoenfeld test and win ratio estimation. RESULTS Among 406 randomly assigned patients, the primary end point win ratio for anselamimab versus placebo was 1.11 (95% CI, 0.83, 1.50; P = .332) and the hazard ratio (HR) for ACM was 0.80 (95% CI, 0.57, 1.13; P = .290). CVH rates in the anselamimab and placebo groups were 0.59 (95% CI, 0.42, 0.83) and 0.89 (95% CI, 0.55, 1.43), respectively ( P = .145). Among patients with kappa isotype (n = 72), the win ratio was 2.06 (95% CI, 0.98, 4.31; P = .100) and anselamimab reduced ACM by 62% versus placebo (HR, 0.38; 95% CI, 0.17 to 0.86; nominal P = .012), and CVH by 71% (IRR, 0.29; 95% CI, 0.10 to 0.87; nominal P = .028) with improvements in Kansas City Cardiomyopathy Questionnaire-Overall Score. There was no clinical benefit observed in the lambda population. Anselamimab was generally well-tolerated; safety data were comparable between treatment arms overall. CONCLUSION Treatment with anselamimab, an antifibril antibody used alongside antiplasma cell dyscrasia therapy, while not meeting the primary end point in the overall population, significantly improved ACM and CVH in patients with kappa AL, potentially offering a new therapeutic option for this isotype.

Abstract Repetitive head impacts sustained during American football have been associated with neuropathological changes such as white matter shear injuries. However, the impact of specific factors, such as age of first exposure and cumulative head impact burden, on white matter integrity remains unclear. This study investigated in vivo white matter microstructural changes using diffusion tensor imaging and tract-based spatial statistics in 165 male former American football players (mean age 57.3 years, range 45–74) and 52 unexposed asymptomatic male controls (mean age 59.4 years, range 45–74) in the DIAGNOSE CTE Research Project. Compared to controls, former football players exhibited significantly higher fractional anisotropy (FA) in 1.97% of the white matter skeleton (1552 voxels; Cohen’s d = 0.587) and higher tissue-corrected FA (FAt) in 1.48% of the white matter skeleton (1004 voxels; Cohen’s d = 0.616). No significant differences were observed for mean diffusivity, axial diffusivity, radial diffusivity, or free water between football players and controls. Among football players, there were no significant differences in the white matter microstructure between players diagnosed with traumatic encephalopathy syndrome and those without the diagnosis. Lower FA was significantly associated with older age (P &lt; 0.00001) and an earlier age of first exposure to tackle football (P &lt; 0.01), while lower FAt was associated with greater cumulative head impact burden, specifically higher linear acceleration (P &lt; 0.04) and rotational force (P &lt; 0.02). This study highlights the influential role of exposure factors on white matter microstructure in former American football players, as well as the utility of diffusion tensor imaging to aid in characterizing the long-term effects of repetitive head impacts in contact sport athletes.

e20629 Background: Concomitant inhibition of the vascular endothelial growth factor (VEGF) pathway together with PD-1 or PD-L1 immune checkpoint blockade has demonstrated synergistic activity in non-small cell lung cancer (NSCLC). However, comparative evidence across individual immune checkpoint inhibitor (ICI) and anti-VEGF combinations remains limited. This network meta-analysis (NMA) aimed to evaluate and compare the efficacy of available ICI plus anti-VEGF combination strategies in NSCLC. Methods: A systematic search of three electronic databases and two clinical trial registries was conducted to identify randomized controlled trials evaluating combinations of ICIs with anti-VEGF agents. A frequentist NMA framework was applied using the netmeta package in R. Hazard ratios (HRs) were used for overall survival (OS) and progression-free survival (PFS), while odds ratios (ORs) were used for objective response rate (ORR). Treatment ranking was performed using P scores. Results: A total of 24 randomized controlled trials were included in the network. For survival outcomes, the combination of nivolumab plus bevacizumab demonstrated significantly improved OS (HR = 0.66, 95% CI 0.50–0.88) and PFS (HR = 0.46, 95% CI 0.27–0.81) compared with standard chemotherapy. In addition, atezolizumab plus bevacizumab was associated with a significant OS benefit over chemotherapy (HR = 0.79, 95% CI 0.65–0.95). Indirect comparisons showed that nivolumab plus bevacizumab significantly improved PFS compared with pembrolizumab monotherapy, as well as pembrolizumab combined with lenvatinib or chemotherapy. Furthermore, nivolumab combined with sitravatinib demonstrated significantly superior OS and PFS compared with ramucirumab and chemotherapy. For ORR assessed using RECIST 1.1, nivolumab-based combinations could not be incorporated into the network due to insufficient data, and no other combination demonstrated a statistically significant advantage over chemotherapy. However, indirect comparisons showed that pembrolizumab plus lenvatinib was superior to lenvatinib monotherapy (OR = 4.76, 95% CI 1.04–25.0). P-score rankings identified nivolumab plus bevacizumab as the top-ranked regimen for survival outcomes, followed by atezolizumab plus bevacizumab. For ORR, pembrolizumab plus lenvatinib ranked highest, followed by atezolizumab plus bevacizumab. Conclusions: Nivolumab-based ICI and anti-VEGF combinations, particularly with bevacizumab and sitravatinib, demonstrate the most favorable survival outcomes in NSCLC. Evidence for ORR remains limited, and further randomized comparisons are required to better define the relative efficacy of these combinations.

e20139 Background: Extensive-stage small cell lung cancer (ES-SCLC) frequently presents with brain metastases, affecting approximately 20% of the patients at diagnosis. The prognostic impact of baseline brain metastases on survival outcomes in patients treated with contemporary chemo-immunotherapy remains unclear, creating uncertainty in first-line treatment selection for this high-risk population. We conducted a systematic review and meta-analysis to evaluate the impact of baseline brain metastases on treatment outcomes in ES-SCLC. Methods: This PRISMA-compliant systematic review and meta-analysis was prospectively registered in PROSPERO. PubMed, Embase, Cochrane CENTRAL, and ClinicalTrials.gov were systematically searched from database inception through January 2026 to identify randomized controlled trials evaluating PD-1/PD-L1-based chemo-immunotherapy versus platinum-etoposide chemotherapy in adults with ES-SCLC. Two reviewers independently screened studies and extracted data, with discrepancies resolved by consensus. Hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS) were pooled separately for patients with baseline brain metastases (BM+) and without brain metastases (BM−) using random-effects models with Hartung–Knapp adjustment. Analyses were performed using R. Prespecified subgroup analyses were conducted based on follow-up duration and immunotherapy regimen. Results: Twelve randomized controlled trials were included. Among patients with baseline brain metastases (BM+), pooled OS from seven studies did not show a significant survival benefit (HR 0.84, 95% CI 0.66–1.08, I² = 0.0%, P = 0.145), nor did pooled PFS from five studies (HR 1.03, 95% CI 0.60–1.79, I² = 0.0%). Subgroup analyses revealed no significant heterogeneity. In contrast, among patients without baseline brain metastases (BM−), pooled OS from nine studies demonstrated a significant survival benefit (HR 0.72, 95% CI 0.69–0.76, I² = 0.0%, P < 0.001), with corresponding improvement in PFS (HR 0.70, 95% CI 0.60–0.82, I² = 0.0%). These findings indicate a differential treatment effect according to baseline brain metastasis status. Conclusions: First-line chemo-immunotherapy does not apprear to confer a significant survival benefit in ES-SCLC patients with baseline brain metastases, reflecting a differential treatment effect by brain metastasis status. These findings suggest that baseline brain metastases should be considered in treatment selection and future clinical trial design and highlight the need for optimized systemic strategies for this high-risk population.
