Abstract Alzheimer's disease (AD) continues to pose a major public health challenge. Since its launch in 2004, the Alzheimer's Disease Neuroimaging Initiative (ADNI) has played a pivotal role in advancing the field by providing a comprehensive, open‐access, longitudinal dataset that integrates neuroimaging, biomarker, genetic, and clinical data related to AD. We used standard literature search methods to identify ∼1830 publications from 2023 to mid‐2025 that used ADNI data or samples. This review highlights key ADNI studies with direct clinical applications. We describe how these have impacted the development and validation of plasma biomarkers, improved clinical trials, assessed AD therapies, and developed methods for diagnosis and prediction using clinical, fluid, and imaging biomarkers. These contributions are underlain by an improved understanding of biological mechanisms of disease progression in AD and highlight ADNI's central role in advancing translational research and accelerating progress toward more effective, individualized care for patients with AD.

Abstract Background Immigrants to the United States often face challenges from limited healthcare access and less healthy environments which contribute to rising obesity and cardiovascular risk. Purpose To assess the feasibility and effectiveness of a community-based social network intervention for cardiovascular risk reduction among Hispanic and Somali adults. Methods A social network-informed, community-based participatory research-derived health promotion intervention was delivered by Hispanic and Somali lay health promoters (HPs) to members of their social networks over 1 year (12 biweekly sessions in months 0-6; 12 biweekly check-ins in months 7-12). Using a closed-cohort stepped wedge cluster randomized design, social networks were randomly assigned to receive the intervention immediately or after a delay of 1 year. Measurements at baseline, 6 months, and 12 months were derived from 6 of the American Heart Association’s “Life’s Simple 7”: BMI, blood pressure, fasting glucose, cholesterol, physical activity and dietary quality (range 0-12, with higher values indicating lower cardiovascular risk). Waist circumference and proportion of participants who achieved >5% body weight loss were also assessed. Results Four hundred seventy-five participants were enrolled among 51 HPs (29 Hispanic; 22 Somali). There was a statistically significant improvement in cardiovascular risk in the intervention group (n = 246) compared with controls (n = 229) at 6 months (0.4 [1.8] vs. −0.1 [1.7]; P = .03) that was not sustained at 12 months (0.5 [1.9] vs. 0.3 [1.8]; P = .38). There was a statistically significant higher proportion of participants who lost >5% of body weight in the intervention group compared with controls at 12 months (37% [15] vs. 18% [7.9]; P = .02). Reductions in weight and waist circumference in the intervention group compared with controls did not achieve statistical significance. Conclusion A social network intervention, delivered by lay HPs was feasible and resulted in a modest improvement of cardiovascular risk and clinically significant weight loss. Clinical Trial Identification Number NCT05136339.

Current spatial T cell receptor (TCR) profiling approaches lack the resolution needed to link clonal identity, transcriptional state, and spatial positioning of individual T cells in the tumor microenvironment. Here, we introduce a spatial TCR profiling strategy that resolves individual T cell clones together with their transcriptional states at single-cell resolution and applied the method to human head and neck squamous cell carcinoma. Presumed tumor-specific T cells were broadly dispersed throughout the tumor microenvironment, and cells of the same clone occupied distinct transcriptional states in different locations: Immune-rich regions contained more plastic or progenitor cells, whereas tumor-dense regions were enriched for exhausted states. Patients exhibited notably different spatial architectures of antitumor T cell responses, revealing variation that was not captured by high-resolution, spatially agnostic methods such as spectral flow cytometry and single-cell RNA sequencing. These results provide a blueprint for dissecting antigen-specific T cell states in human tumors and reveal how T cell states are spatially coordinated with local cues across the tumor microenvironment.

Pneumotachographs (also called pneumotachometers and anemometers) measure airflow against a fixed resistance and may be found in respirometers, mechanical ventilators, incentive breathing devices, diagnostic spirometers, and other pulmonary function testing instruments. The Fleisch design is the oldest, but it requires a costly pressure transducer and analog-to-digital converter and its accuracy is affected by gas-viscosity differences and by airflow turbulence. Besides the Fleisch, ceramic, screen, orifice, hot-wire, turbine, vortex, and ultrasonic pneumotachographs are now available. They solve some of the Fleisch's problems but cannot be used in all applications. All instruments with these devices must be carefully and completely calibrated at the time of installation and routinely calibrated or checked thereafter.

PURPOSE Approximately three quarters of patients with sarcoma report financial toxicity, defined as the psychosocial and economic burden of cancer care. The Comprehensive Score for Financial Toxicity (COST) is a screening questionnaire validated in patients with cancer. However, its use is not widespread in sarcoma care, likely in part due to its complexity. This study aimed to characterize financial toxicity in patients with sarcoma and evaluate whether shorter screening tools can identify high-risk patients. METHODS We conducted a survey and retrospective cohort study of patients treated for sarcoma at a large, academic sarcoma center in 2016-2024. Patients completed the COST questionnaire (11 graded questions, each scored on a five-point Likert scale from 0 to 4) and the shorter, four-question Worry about Affording Healthcare Scale (WAHS). We obtained clinical information from the electronic health record. We used descriptive statistics to summarize responses to COST, Pearson's correlation coefficient to assess the association between WAHS and COST, and stepwise Spearman correlations to evaluate whether an abbreviated (1-4 question) version of COST correlated highly with total COST score. RESULTS Among 205 participants, the mean COST score was 20/44 (standard deviation = 6; lower scores indicate greater financial toxicity). Respondents worried most about job loss (mean COST: 0.99) and family finances (mean COST: 1.11). WAHS was weakly correlated with COST (r = 0.47, P < .01). A four-item abbreviated COST tool was strongly correlated with the total COST (ρ = 0.906, P < .0001) and demonstrated high sensitivity (96%) and moderate specificity (75%). CONCLUSION An abbreviated four-item COST tool could act as a clinically feasible, accurate screening tool after external validation. Routine financial toxicity screening could facilitate timely detection and referral to essential financial navigation resources.

Background Psychiatric comorbidities are increasingly recognised in demyelinating diseases, yet their frequency and timing in myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) are not well defined. We aimed to characterise the spectrum and temporal pattern of psychiatric illness in MOGAD and compare to multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) with aquaporin-4 antibody (AQP4-IgG). Methods We conducted a cross-sectional study of patients with MOGAD (n=388), age-matched and sex-matched MS (n=257) and AQP4-IgG-positive NMOSD (n=58) evaluated at Mayo Clinic (1991–2025). Psychiatric diagnoses, timing relative to the first attack and patient-reported outcomes were extracted from electronic health records (EHRs). Complementary analyses were conducted using the NeuroBlu real-world EHR database. Results Among 388 patients with MOGAD, 54.8% had ≥1 psychiatric disorder, most commonly anxiety (47.7%), depression (36.6%) and attention-deficit/hyperactivity disorder (ADHD, 9%). After the first attack, 33.3% of patients with MOGAD developed a new psychiatric disorder, often within the first year. MOGAD showed a lower frequency of depression versus MS (36.6% vs 47.5%, p=0.02) but similar rates of anxiety and ADHD. Temporal patterns differed: psychiatric disorders often appeared years before onset in MS but clustered shortly after onset in MOGAD. NeuroBlu analyses supported high rates of psychiatric disorders across the three conditions. Conclusion Psychiatric comorbidities are common in MOGAD, particularly depression and anxiety, typically emerging close after onset, whereas in MS they often preceded onset by years. These findings underscore the need for routine psychiatric screening in MOGAD and highlight unresolved questions regarding whether, and to what extent, MOG-IgG-mediated inflammatory demyelination contributes to psychiatric vulnerability.

These NCCN Guidelines for Distress Management discuss the identification and treatment of psychosocial problems in patients with cancer. They are intended to assist oncology teams to identify patients who require referral to psychosocial resources and to give oncology teams guidance on interventions for patients with significant distress. These guidelines also provide guidance for social workers, certified chaplains, and mental health professionals by describing treatments and interventions for various psychosocial problems as they relate to patients with cancer. These NCCN Guidelines Insights summarize the panel’s most recent recommendations regarding standards of care for distress management in patients with cancer and implementation of these standards, including application of evidence-based care delivery models, such as the collaborative care model.
