ABSTRACT INTRODUCTION Neighborhood deprivation increases dementia risk, although mechanisms remain unclear. We tested a framework in which modifiable risk factors and cerebral small vessel disease (SVD) mediate the link between neighborhood deprivation and cognition. METHODS In 585 cognitively healthy midlife adults (ages 40–59), neighborhood deprivation was derived from postcodes, cognition was assessed using the COGNITO, lifestyle risk factors were measured using clinical assessments, and SVD (white matter hyperintensities, lacunes, microbleeds, perivascular spaces) was assessed on 3T magnetic resonance imaging. Multivariate analyses examined association pathways among these variables. RESULTS Neighborhood deprivation was associated with poorer cognition ( r = 0.36, p < 0.001), greater prevalence of modifiable risk factors ( r = 0.36, p < 0.001), and greater SVD burden ( β = 0.18, p = 0.008). Serial mediation showed that the effects of deprivation on cognition were indirect, possibly operating via lifestyle risk and SVD, explaining 20% of the total effect, whereas SVD alone explained 28%. DISCUSSION Neighborhood disadvantage relates to poorer cognition, possibly mediated through vascular risk factors and cerebrovascular disease. Highlights Neighborhood deprivation linked to poorer cognition in healthy midlife adults Deprivation linked to small vessel disease (SVD) and modifiable risk factors (chiefly cardiovascular risk) Association between deprivation and cognition mediated by modifiable risk and SVD Mediation was exclusive to hypertensive SVD, but not cerebral amyloid angiopathy (CAA)‐related SVD

Introduction Semaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1RA) used to treat type 2 diabetes mellitus (T2D), has potential associations with higher rates of diabetic retinopathy (DR) complications including proliferative DR (PDR) and diabetic macular edema (DME). The purpose of this study was to determine whether an association exists between semaglutide and PDR and treatment-requiring DR/DME. Research design and methods This was a retrospective cohort study of 14 databases (six administrative claims and eight electronic health records) in the Observational Health Data Sciences and Informatics Evidence Network. Adults with T2D on semaglutide, other GLP-1RA (dulaglutide, exenatide), or non-GLP-1RA medications (empagliflozin, sitagliptin, glipizide) from 1 December 2017 to 31 December 2023 were included. The association between semaglutide and PDR or treatment-requiring DR/DME was assessed using an active-comparator cohort design comparing new users of semaglutide as second-line T2D treatment to those on other GLP-1RAs and non-GLP-1RAs. Propensity score-adjusted Cox proportional hazards models were used to estimate hazard ratios (HRs). Network-wide HR estimates were generated using a random-effects meta-analysis. Results The study included 810 390 new semaglutide users for T2D. PDR risk for semaglutide was similar to dulaglutide (HR 0.81, 95% CI 0.42 to 1.54, p=0.51), empagliflozin (HR 0.83, 95% CI 0.53 to 1.30, p=0.41) and sitagliptin (HR 0.83, 95% CI 0.45 to 1.55, p=0.57) but was lower than glipizide (HR 0.59, 95% CI 0.39 to 0.88, p=0.01). The risk for treatment-requiring DR/DME for semaglutide was similar to empagliflozin (HR 0.66, 95% CI 0.43 to 1.02, p=0.06) but lower than dulaglutide (HR 0.53, 95% CI 0.31 to 0.91, p=0.02), sitagliptin (HR 0.46, 95% CI 0.26 to 0.81, p=0.008) and glipizide (HR 0.55, 95% CI 0.33 to 0.91, p=0.02). Conclusions and relevance We did not identify increased risk for either PDR or treatment-requiring DR/DME comparing semaglutide with other GLP-1RAs or non-GLP-1RAs. Patients with T2D should still undergo close eye care follow-up, particularly when initiating new antihyperglycemic medications.

Abstract The addition of pembrolizumab to preoperative radiotherapy (RT) improved disease-free survival (DFS) for patients with stage III undifferentiated pleomorphic sarcoma (UPS) and dedifferentiated/pleomorphic liposarcoma (LPS) in the randomized SU2C-SARC032 trial. To precisely identify patients who benefit from pembrolizumab and RT, we performed comprehensive multi-omics profiling of pre- and post-treatment tumor and blood samples, including bulk RNA-seq, flow cytometry, and cytometry by time of flight. Additionally, we built a single-cell RNA-seq atlas spanning 65,786 cells from UPS and LPS to recover single-cell states in bulk tumor samples using digital cytometry. Two opposing tumor microenvironments (TMEs), immune-cold sarcoma ecotype 1 (SE1) and immune-hot sarcoma immune class E (SIC E), benefited from pembrolizumab. Pembrolizumab combined with RT caused an overall increase in activated CD8 + T cells, CD56 low NK cells, and T cell receptor diversity, while diminishing matrix-remodeling stromal cells and sarcoma cells. Our findings identify different mechanisms of response to pembrolizumab in localized, high-risk UPS/LPS and suggest that sarcoma TME signatures may identify patients most likely to benefit from adding pembrolizumab to preoperative RT.

Background. Assessment tools in surgical education help identify improvement areas for trainees. We developed and present validity evidence for a novel Transplant Operative Assessment Tool to optimize technical feedback for surgical trainees in transplantation. Methods. The Transplant Operative Assessment Tool assesses learners on anatomy, technical skills, judgment, and communication. Performance is rated across 5 competency levels. Content validity evidence included a construct map using existing literature and expert cognitive interviews. Ratings were used to develop an item response theory calibration, which was then used to evaluate the tool and provide validity evidence. Results. Eighty-two assessments for 28 trainees (16 residents, 12 fellows) were completed by 25 faculty surgeons across 4 programs. Fifty-six kidney transplants, 13 liver transplants, and 13 donor nephrectomies were assessed. The mean assessment completion time was 4.1 ± 4.3 min. Internal structure validity was evaluated by calculating item infit (range, 0.86–1.15), indicating a strong model fit and confirming a high quality of items. Internal consistency was also high (Cronbach’s alpha = 0.94). There was a positive correlation between ratings and training level ( P < 0.01), indicating strong discriminatory power. Warm ischemia time for transplant operations did not correlate with performance ( P = 0.16). Conclusions. These data provide validity evidence for a novel operative assessment tool. This instrument can measure performance, monitor progress, document competency, and has the potential to provide valuable feedback.

Objective A patient‐centered approach for chronic disease management, including systemic lupus erythematosus (SLE), aligns treatment with patients’ values and preferences, leading to improved outcomes. This paper summarizes how patient experiences, perspectives, and priorities informed the American College of Rheumatology (ACR) 2024 Lupus Nephritis (LN) and 2025 SLE screening, treatment guidelines. Methods We completed a cross‐sectional qualitative study using content analysis of two Patient Panel meetings for the ACR LN and SLE guidelines. Key themes were presented by Patient Panel representatives during Voting Panel Meetings along with evidence for each recommendation, to ensure comprehensive discussions and align treatment recommendations with patients’ priorities and values. Results Nineteen people (90% women) with diagnoses of SLE and/or LN participated in the Patient Panels and 17 consented to use their feedback for analysis. Thematic analysis of their discussions revealed nine patient‐reported key themes in three domains: (1) treatment and monitoring of LN and SLE: medication side effects, daily function, treatment goals, and monitoring and screening; (2) clinical communication: strategies to optimize communication and provider and structural impediments to effective communication; and (3) improving transparency and information sharing: clinical trial participation, and medical costs and insurance coverage. These themes were actively incorporated into discussions during the Voting Panels for the ACR LN and SLE guidelines. Conclusion This work supported the integration of patient experiences in the clinical practice guideline development process and aligned recommendations with real‐world patient experiences and priorities, thereby enhancing the clinical applicability of the ACR LN and SLE guidelines. image

Background: Macromastia causes significant physical and psychological distress in adolescents. Although reduction mammaplasty alleviates these symptoms, the mental health impact of macromastia in younger populations remains underexplored. This systematic review and meta-analysis aimed to evaluate mental health and quality of life outcomes in adolescents/young women undergoing reduction mammaplasty. Methods: A systematic search of PubMed, Embase, and the Cochrane Central Register of Controlled Trials was conducted from inception to September 2024. Studies reporting mental health or quality of life outcomes through the BREAST-Q, Short Form-36, Rosenberg Self-Esteem Scale, and Eating Attitudes Test were included. Odds ratios and mean difference with 95% confidence intervals were pooled using a random-effects model. Heterogeneity was assessed with I 2 statistics. The Risk of Bias in Nonrandomized Studies of Interventions tool was used to assess study quality. Meta-analysis was performed on 4 BREAST-Q domains. Results: Of 701 articles identified, 8 observational studies involving 660 patients were included. Pooled BREAST-Q scores postsurgery showed significant improvements across all 4 domains. Improvement in Short Form-36, Rosenberg Self-Esteem Scale, and Eating Attitudes Test scores was noted in individual studies, though meta-analysis was limited by incomplete data. Conclusions: These results indicate that reduction mammaplasty significantly improves the physical, psychosocial, and sexual well-being of adolescents/young women with macromastia.

Background: Atrial fibrillation (AF) significantly impacts quality of life (QoL) and is often observed in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). Acoramidis achieves near-complete (≥90%) transthyretin (TTR) stabilization and is approved in the USA, the UK, Europe and Japan for the treatment of ATTR-CM in adults. In the phase 3 ATTRibute-CM study (NCT03860935), acoramidis treatment significantly reduced the time to all-cause mortality (ACM) or first cardiovascular-related hospitalization (CVH) at Month 30, and resulted in improved 6-minute walk distance (6MWD), Kansas City Cardiomyopathy Questionnaire-Overall Summary (KCCQ-OS) scores and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels relative to placebo. The clinical efficacy of acoramidis has not yet been reported in patients with ATTR-CM and with an AF or atrial flutter (AFL) diagnosis at baseline. Research Question: How does acoramidis treatment affect ACM or first CVH, 6MWD, KCCQ-OS scores, and NT-proBNP levels at Month 30 in participants with ATTR-CM with or without AF/AFL diagnosis at baseline? Methods: The ATTRibute-CM study design has been previously published. This post hoc analysis included participants in the modified intention-to-treat population (N=611) grouped by AF/AFL diagnosis at baseline (defined as recorded AF medical history or the presence of AF or AFL on an ECG at enrollment). The rate of ACM or first CVH at Month 30 was compared between groups using a stratified Cox proportional hazards model. Changes from baseline to Month 30 in 6MWD, KCCQ-OS scores and NT-proBNP levels were summarized descriptively. Results: Overall, 62.8% (384/611) of participants had an AF/AFL diagnosis at baseline (acoramidis: 255/409, placebo: 129/202). These participants had lower mean 6MWD and KCCQ-OS scores and higher median NT-proBNP levels than those without AF/AFL diagnosis at baseline. Treatment with acoramidis reduced ACM or first CVH, slowed the decline in 6MWD and KCCQ-OS scores and blunted the rise in NT-proBNP compared with placebo, regardless of AF/AFL diagnosis at baseline ( Table ). Conclusions: Acoramidis improved clinical outcomes (ACM, CVH), functional status, QoL and NT-proBNP levels relative to placebo in participants with ATTR-CM, regardless of AF/AFL diagnosis at baseline.

Background: Pre-clinical animal studies have demonstrated improved cerebral blood flow and neurological survival with Automated Head Up Position (AHUP) cardiopulmonary resuscitation (CPR) as compared to flat conventional (C) CPR. AHUP CPR consists of 1) automated head and thorax elevation 2) active compression decompression CPR and 3) an impedance threshold device. Subsequently, observational propensity-matched studies of out-of-hospital cardiac arrest (OHCA) patients demonstrated a time-dependent association between survival with intact neurological function (SNF) and application of AHUP CPR. However, comparison of AHUP CPR outcomes with contemporaneous C-CPR controls is lacking. Hypothesis: Use of AHUP CPR for OHCA by first responder agencies will demonstrate a higher incidence of SNF compared to C-CPR outcomes from a national registry Methods: Data from the previous 5 years (2020-2024) from an AHUP-CPR Registry comprised of OHCA patients routinely treated by first responders with AHUP CPR were compared with data from the Cardiac Arrest Registry to Enhance Survival (CARES). Patient demographics, arrest characteristics, ROSC, SHD, and SNF were recorded. SNF was defined as a Cerebral Performance Category 1 or 2 at hospital discharge. A two-sample test of proportions was used for outcome comparisons. Results: Nine AHUP registry sites (MN, FL, TN, IL, OK, VA, AL, IA, MI) were included. Summary 5-year demographics (Table 1) and clinical outcomes (Table 2) are presented. For 2020-2024 AHUP sites, the average time (mm:ss, SD) from 9-1-1 call to start of CPR was 9:09 (4:37) and time to start of AHUP CPR was 12:46 (5:57). The AHUP registry had a higher 5-yr incidence of SNF versus the CARES registry (difference 2.8%, 95% CI 1.8-3.8, p < 0.00001). This difference was consistent year over year (Figure 1). Secondary outcomes of sustained return of spontaneous circulation and survival to hospital discharge in the AHUP registry were also significantly higher than CARES registry data (Table 2). Conclusions: Over a 5-year period, an unadjusted analysis of aggregate data from two OHCA patient registries demonstrated that the incidence of survival with intact neurological function was higher in patients treated with AHUP CPR as part of first responder care versus patients treated with more conventional CPR methods.

Introduction: Cardiovascular risks following SARS-CoV-2 infection are incompletely defined. We evaluated evolving cardiovascular outcomes across COVID-19 variant eras using a large community-based cohort to inform risk stratification and clinical care. Methods: We conducted a retrospective cohort study of 162,471 adults with COVID-19 between March 2020 and December 2023 using the Rochester Epidemiology Project. Patients were stratified by variant era (Pre-Delta, Delta, and Omicron). Cardiovascular outcomes included major adverse cardiovascular events (MACE: myocardial infarction, stroke, death), ischemic and inflammatory heart disease, thrombotic events, and dysrhythmias. Diagnoses were identified using ICD-10 codes and validated in a subset. Cumulative incidence was estimated using Kaplan-Meier and competing risk models. Cox proportional hazards regression was used to assess differences by era and age. Results: MACE occurred in 4,922 patients, primarily in those ≥80 (2-year incidence: 17%). Event rates peaked within 30 days post-infection, with marked variation by variant. In patients ≥80, 30-day MACE risk was highest in the Pre-Delta (HR 3.85; 95% CI, 3.14–4.71) and Delta (HR 2.72; 95% CI, 2.13–3.47) eras versus Omicron. After 30 days, event rates fell and era differences narrowed. Thrombotic events (n=2,090; 1.4%) decreased across eras. Ischemic and inflammatory heart disease rates were stable. Myocarditis/pericarditis were rare (0.1%) without age trends. Dysrhythmias affected 6,765 patients (2-year incidence: 4.9%) and rose with age (2.0% in <40 vs. 19.9% in ≥80). Within 30 days, risk was higher in the Pre-Delta and Delta eras for age ≥40, especially ≥80 (Delta HR 3.08; 95% CI, 2.08–4.56) and 60–79 (HR 2.23; 95% CI, 1.75–2.85). Among those 40–59, Delta posed the highest risk (HR 2.74; 95% CI, 1.94–3.86 vs. Pre-Delta HR 1.77; 95% CI, 1.26–2.49). No differences were observed in <40. Beyond 30 days, risk converged across variants. Conclusion: Cardiovascular risk after SARS-CoV-2 infection was concentrated in the first 30 days, with attenuation thereafter. While MACE and thrombotic event rates declined over time, early dysrhythmia risk varied by variant and age, especially in older adults. These findings define a time-sensitive, variant-specific risk window and support short-term, risk-stratified post-COVID monitoring. This work informs targeted follow-up protocols by infection era and age, with implications for quality improvement, resource use, and equitable care.

Background: Calcific aortic valve stenosis (CAVS) is characterized by the progressive accrual of aortic valvular calcium (AVC), resulting in impaired valvular compliance and mechanics and impaired cardiac function leading to heart failure (HF). In a phase 2 trial of 23 patients with moderate CAVS, ataciguat (ATA), a soluble guanylate cyclase activator, relative to placebo slowed the deposition of AVC, decreases in aortic valve area (AVA; by continuity equation), and increases in diastolic dysfunction and left ventricular (LV) mass. ATA may have other favorable effects on ventricular, valvular, and/or vascular pathophysiology relevant to patients with CAVS. Hypothesis: We hypothesized that slowing the rate of AVC deposition is associated with improvements in valvular compliance and in measures of cardiac structure and function. Methods: A phase 2 study randomized patients with moderate CAVS 1:1 to receive ATA 200 mg/day or placebo for up to 12 months (NCT02481258). The primary endpoint was change in AVC assessed by cardiac CT, and measures of aortic valve function and cardiac structure and function were also assessed. AVA was calculated by the Modified Gorlin (Hakki) equation to additionally assess valvular compliance. Correlations between AVC, AVA, and other measures of cardiac structure and function were assessed by exploratory linear mixed models. Results: Changes in AVC from baseline were negatively correlated with changes in AVA (slope = −0.0002 [95% CI −0.0004, 0.0001]; Figure 1), such that patients with the least AVC deposition had minimal changes in AVA. Reciprocally, changes from baseline in AVA were positively correlated with changes in cardiac output (CO; slope = 0.16 [95% CI 0.13, 0.18]; Figure 2). Treatment with ATA, compared with placebo, was associated with improvements in systolic function. Changes in AVC deposition correlated with changes in CO (slope = −0.0007 [95% CI −0.0021, 0.0008]; Figure 3), and measured improvements in CO were generally more observed in patients with less of an increase in AVC, which were more frequently observed in those treated with ATA compared with placebo. Conclusions: These data suggest that slowing the rate of AVC deposition with ATA may result in improvements in CO through improved myocardial function and valvular compliance. Larger controlled trials are needed to assess such favorable myocardial/valvular effects that may help to preserve functional capacity and slow progression to HF.
