BACKGROUND: Bicuspid aortic valve (BAV) is a frequent congenital heart defect with a high heritability. Despite this, only a limited number of genes have been associated with the disease, and the molecular mechanisms remain unexplained in most cases. This study aimed to further understand the genetic architecture of BAV. METHODS: A genome-wide association study meta-analysis including 9631 cases among 65 677 participants was performed. Genes were prioritized using transcriptomic analyses based on RNA sequencing in relevant tissues, including human fetal and adult aortic valves. The impact of the knockdown or knockout of 4 candidate genes on cardiac development was verified in zebrafish. A polygenic risk score was developed, its association with BAV was evaluated in an independent cohort, and its association with a wide range of phenotypes (n=976) was evaluated in UK Biobank (n=355 618 individuals). RESULTS: Thirty-six genomic loci were identified, including 32 that were not described previously. Among the prioritized genes, KANK2 and ERBB4 were identified as potentially causal through transcriptomic analyses, colocalization, and Mendelian randomization based on gene expression in human aortic valves (n=484), whereas PRDM6 and STRN were prioritized using similar analyses from aortic (n=326) and left ventricular tissues (n=326), respectively. Targeting 4 candidate genes ( WNT4 , LEF1 , STRN , and KANK2 ) in zebrafish led to disruption in cardiac development. A polygenic risk score was associated with an odds ratio of 2.07 (95% CI, 1.90–2.25; P =5.43×10 -62 ) per SD for BAV and significantly associated with thoracic aortic aneurysm and atrial fibrillation in UK Biobank. CONCLUSIONS: This study supports a significant polygenic contribution to BAV, where the combination of multiple common variants in genes involved in heart morphogenesis disrupts aortic valve development.

We provide the first longitudinal and most comprehensive analysis of the intrarenal microvasculature in a slowly progressive model of autosomal dominant polycystic kidney disease (ADPKD) and integrate the findings with studies in a young cohort of individuals with ADPKD. We identified vasculature-related pathways that could be targeted for therapeutic interventions and contribute promising, noninvasive biomarkers in patients with ADPKD. Alterations of the intrarenal microcirculation may affect drug delivery; a better understanding of its longitudinal changes may aid in treatment management.

Abstract In a real-world analysis of brexucabtagene autoleucel recipients with relapsed/refractory B-cell acute lymphoblastic leukemia (N = 278), lack of response to prior blinatumomab correlates with significantly worse following chimeric antigen receptor T-cell therapy outcomes.

Importance A greater proportion of older patients (age ≥65 years) are undergoing thyroidectomy amidst an aging population. Given the elusive results in the literature, clarifying whether older patients face different thyroidectomy safety profiles is crucial for optimizing risk assessment and patient counseling. Objective To evaluate the association between older age (age ≥65 years) and thyroidectomy safety by comparing endocrine-related complications, including recurrent laryngeal nerve injury, hypocalcemia, hematoma, and mortality in older compared with younger patients. Data Sources Ovid MEDLINE, CINAHL, Ovid Embase, and the Cochrane Library were systematically searched from inception to May 29, 2025; only English-language studies were included. Study Selection Cohort studies comparing thyroidectomy outcomes between older and younger patients and reporting endocrine-related complications were included. Two independent reviewers screened abstracts and full texts. Of 3192 studies identified, 11 met inclusion criteria. Data Extraction and Synthesis Two independent reviewers extracted data following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Risk of bias across studies was evaluated using the ROBINS-I (Risk of Bias in Nonrandomized Studies of Interventions) tool. Random-effects models were used to pool data. Main Outcomes and Measures Incidence of recurrent laryngeal nerve injury, hypocalcemia, and hematoma; odds ratios (ORs) with 95% CIs were calculated. Results The analysis included 11 studies with a total of 427 886 patients of whom 104 232 (24.4%) were older adults (≥65 years). Older adults had greater odds of overall recurrent laryngeal nerve injury (2.3% vs 1.0%; OR, 1.58; 95% CI, 1.15-2.16; I 2 = 76%), hematoma (2.4% vs 1.0%; OR, 2.32; 95% CI, 1.70-3.16; I 2 = 0%), and mortality at last follow-up (0.3% vs 0.01%; OR, 11.09; 95% CI, 1.77-69.52; I 2 = 90%) compared with younger patients. However, rates of overall hypocalcemia (OR, 0.80; 95% CI, 0.61-1.05; I 2 = 71%) and wound complications (OR, 1.38; 95% CI, 0.92-2.06; I 2 = 0%) were similar. Conclusions and Relevance This systematic review and meta-analysis found that thyroidectomy is safe in older patients, with only small absolute increases in recurrent laryngeal nerve injury, hematoma, and mortality despite statistical significance. These findings support individualized counseling and perioperative planning while acknowledging the overall safety of thyroidectomy in this population.

ABSTRACT Background Immune checkpoint inhibitors (ICIs) have emerged as promising agents for the management of advanced HCC. By reducing tumour burden, ICIs may serve as a downstaging/bridging tool to improve transplant candidacy. The aim of this study was to assess the safety of patients receiving pre‐LT ICIs. Methods Multicenter, retrospective cohort study from January 2018 to December 2024, including 48 patients who received ICIs prior to LT (ICI cohort). A control cohort (non‐ICI cohort) was built (1:3) using propensity score matching including 144 patients who underwent LT for HCC without prior ICI. Results Within the ICI cohort ( N = 48) rejection occurred in 9 patients (18.8%), all biopsy‐proven, with a median onset of 31 days post‐LT (12.0–182.0). The median washout period was 60 days (13–96). Patients experiencing rejection had shorter washout periods ( p = 0.029). All rejection episodes were successfully managed; two were steroid‐resistant, one requiring re‐transplantation. There were no rejection‐related deaths. Of the 5 patients with HCC recurrence, 60% received ICI for < 90 days ( p = 0.027). Comparison between the ICI and non‐ICI cohort revealed no significant differences in rejection rates (18.8% vs. 19.4%, p = 0.916), graft failure, HCC recurrence, or overall mortality. Overall survival (OS) did not differ between ICI and non‐ICI patients ( p = 0.625) or between those with and without rejection ( p = 0.119). Rejection was not associated with increased mortality, with deaths primarily attributed to infection or HCC recurrence. Conclusion Our results demonstrate that rejection rates were similar in patients receiving ICIs pre‐LT and it can be safely managed.

Abstract Rationale Neurodevelopmental disorders (NDDs) are characterised by significant challenges in communication, social interaction, and adaptive function, often impacting quality of life. Previous studies support genetic influences on the communication abilities of individuals with NDD, but were either limited to single genetic conditions or to small cohorts with a limited selection of communication measures. Methods We analysed caregiver-reported communication abilities in 79,518 individuals with NDD from the Simons Searchlight and SPARK registries: 4,439 with a CNV-based or monogenic NDD and 75,079 with autism spectrum disorder (ASD) without a known genetic cause (idiopathic ASD) as controls. For analysis, we a priori selected 10 communication-related measures based on their availability in the study cohorts, coverage of distinct communication aspects, and their frequent use in neurodevelopmental phenotyping, yielding 177,328 data points across all study cohorts. The individuals in the Searchlight registry were divided into a Discovery cohort (the 15 most prevalent genetic NDD conditions) and a Confirmation cohort (all other genetic NDD conditions). A second Confirmation cohort was generated using all individuals with genetic ASD forms from the SPARK registry. We then tested each of the three case cohorts and each genetic condition represented in the Discovery cohort against the ASD control cohort. Developmental trajectories were assessed through testing of participants grouped by age at evaluation. Results Measure-level analyses demonstrated significant associations between genetic status and communication abilities, differences in communication abilities between classes of genetic variants (monogenic vs. CNV-based NDDs), and variability between specific genetic NDD conditions. CNV-based NDDs showed milder communication impairment, outperforming idiopathic ASD controls in 9/10 communication measures, whereas monogenic NDD conditions had more pervasive impairments, especially in verbal communication. Although impaired in verbal communication, five monogenic NDD conditions showed at least suggestive strengths in nonverbal and social communication relative to idiopathic ASD controls ( CSNK2A1 , CTNNB1 , SETBP1 , MED13L , and PPP2R5D ), specifically in using gestures. Developmental trajectory analyses revealed STXBP1 as the gene group at highest risk of developmental stagnation in communication abilities. Conclusions These findings underscore the potential of precision speech-language pathology (SLP) approaches tailored to the specific verbal and nonverbal communication strengths and weaknesses of genetic groups. We also provide evidence for measurable improvements and declines in communication abilities with age at the group level, highlighting the need for developmentally informed care. By integrating genetic insights into clinical practice, precision SLP approaches may enhance communication outcomes and developmental progress and improve quality of life for individuals with genetic NDDs.

Alcohol use disorder (AUD) is a significant public health challenge, affecting multiple organs and organ systems, and fetal health. Additionally, AUD also significantly contributes to self-harm and road accidents. Beyond its health effects, AUD creates economic and political challenges, including escalating treatment costs and the complex alcohol regulation policies. Despite global impact, AUD remains under-addressed in countries like India due to cultural norms and limited resources. Early recognition of AUD is vital for better outcomes, relying on thorough clinical evaluation and patient history. However, denial, inebriation, or lack of awareness often delays diagnosis. Imaging techniques like ultrasound, CT, and MRI effectively depict AUD-related organ damage and aid in detecting chronic alcohol use. Radiologists play a crucial role in identifying these manifestations, contributing to its early detection and treatment. This review article highlights the imaging of alcohol use related disorders and diseases affecting different organs and organ systems at various stages. The review is presented in two parts: the first focuses on alcohol burden, alcohol metabolism and toxicity, and imaging findings of AUD-related abdominal diseases and disorders.

Introduction: Underrepresented in family medicine (URiFM) physicians hold 14.42% of US family medicine faculty positions. Scholarship is critical to academic advancement. We explored family medicine department chairs’ racial allyship, their identification of scholarship barriers faced by URiFM faculty, and the existence of initiatives to increase scholarship. Methods: We used the 2022 Council of Academic Family Medicine Educational Research Alliance (CERA) Department Chair survey to examine the percentage of chair-perceived URiFM departmental faculty members and their scholarly productivity and chair-perceived barriers to productivity and initiatives. We measured chairs’ racial allyship. We calculated descriptive statistics, weighted means, and used regression to identify whether chair characteristics or allyship scores were associated with support of URiFM faculty scholarship initiatives and identification of the minority tax. Results: One hundred nine chairs completed the survey (response rate 48.4%); 13.76% identified as URiFM; 6.4% reported they perceived more than 50% of their faculty were URiFM; 90.8% of chairs did not report programs supporting URiFM scholarship; and 44.9% described URiFM faculty scholarly output as minimal or none. Department chairs’ mean allyship score was 2.59 (SD = 0.80) out of 5. Chairs ranked lack of research skills and lack of funding for protected time higher than the minority tax from a list of scholarship barriers. We found no association between chair allyship scores, chair characteristics, total department full-time equivalents, and the existence of a URiFM faculty scholarly support program. Discussion: Despite chairs reporting low URiFM faculty scholarly output, few departments have a dedicated support program. Chair allyship scores were not associated with identification of scholarship barriers or existence of scholarship programs.

Abstract Metabolic disorders such as obesity, type 2 diabetes, and dyslipidaemia are major drivers of cardiovascular risk and have reached epidemic levels in Western populations. Recent advances in clinical research have uncovered unexpected and often beneficial effects of pharmacological classes of metabolic drugs on cardiovascular outcomes, revealing complex interactions between metabolism and cardiac pathology. Despite their clinical efficacy, the molecular and cellular mechanisms through which many of these agents act remain only partially understood. This gap in knowledge underscores the urgent need for fundamental research that not only dissects the biology of metabolic disorders and cardiovascular disease but also reveals the mechanistic basis of existing and emerging therapies, thereby enabling rational therapeutic development. This scientific statement, developed by researchers from the European Society of Cardiology (ESC) Council on Basic Cardiovascular Science and several ESC Working Groups, provides a state-of-the-art overview of the emerging molecular and cellular pathways linking metabolic abnormalities with vascular and cardiac disease. By illuminating these critical connections and unresolved questions, this article aims to catalyse innovation in the prevention and management of cardiovascular disease in the context of metabolic dysfunction and to suggest new directions for future research.

Background and Objectives: Cervical artery dissection (CeAD) is a leading cause of ischemic stroke in younger adults, yet sex-specific variations in its clinical presentation, imaging characteristics, and outcomes remain underexplored. We aimed to evaluate these differences using data from a large, multicenter registry. Methods: We analyzed data from the STOP-CAD registry, which includes patients with radiologically confirmed non-traumatic CeAD enrolled between 2015 and 2021 across multiple centers. Clinical and imaging characteristics were compared between men and women using multivariable logistic regression. Outcomes assessed included ischemic stroke recurrence at 180 days, excellent functional outcome (modified Rankin Scale [mRS] 0–1) at 90 days, symptomatic intracerebral hemorrhage (sICH), and mortality. Results: Among 4,023 patients with CeAD, 1,783 (44.6%) were women. Compared to men, women were younger (median age: 42 vs 50 years), more likely to have a history of migraine (26.9% vs 8.3%) and connective tissue disorders (14.3% vs 5.8%), and presented more frequently with non-ischemic symptoms such as headache, neck pain, or tinnitus (adjusted OR [aOR] 2.0; 95% CI, 1.8–2.3; p<0.001). Women had significantly higher odds of vertebral artery dissection (OR, 1.3; 95% CI, 1.2-1.5; p<0.001), multivessel involvement (OR, 2.1; 95% CI, 1.7-2.5; p<0.001), and pseudoaneurysm formation (OR, 1.3; 95% CI, 1.1-1.6; p=0.003). Despite these differences, there was no significant sex-based difference in key clinical outcomes: excellent functional recovery at 90 days (OR 0.94; 95% CI 0.76-1.15 p=0.542), ischemic stroke recurrence at 180 days (OR 0.56 CI 0.23-1.3 p=0.213), or mortality (OR 0.83; 95% CI 0.47-1.48, p=0.529). Conclusion: In this large international cohort, we observed women with CeAD were younger, more likely to present with non-ischemic symptoms with distinct imaging features. These underscore the need for heightened clinical suspicion of CeAD in women presenting with atypical symptoms, even in the absence of ischemic deficits or conventional vascular risk factors, and suggest that sex-specific phenotyping may enhance diagnostic accuracy and early management.
