Structural and functional alterations in the brain's reward circuitry are present in cocaine use disorder (CocUD), but their molecular underpinnings remain unclear. To investigate these mechanisms, we performed single-nuclei multiome profiling on postmortem caudate nucleus tissue from six individuals with CocUD and eight controls. We profiled 30,030 nuclei, identifying 13 cell types including D1- and D2-medium spiny neurons (MSNs) and glial cells. We observed 1485 differentially regulated genes and 10,342 differentially accessible peaks, with alterations in MSNs and astrocytes related to neurotransmitter activity and synapse organization. Gene regulatory network analysis identified transcription factors including ZEB1 as exhibiting distinct CocUD-specific subclusters, …

Hypertensive disorders of pregnancy (HDP), including preeclampsia, affect 1 in 6 pregnancies, are major contributors to maternal morbidity and mortality, yet lack precision medicine strategies. Analyzing transcriptomic data from a prospectively-collected diverse cohort (n = 9102), this study reveals distinct RNA subtypes in maternal blood, reclassifying clinical HDP phenotypes like early/late-onset preeclampsia. The placental gene PAPPA2 strongly predicts the most severe forms of preeclampsia in individuals without pre-existing high risk factors, months before symptoms, and its overexpression correlates with earlier delivery in a dose-dependent manner. Further, molecular subtypes characterized by immune genes are upregulated in less severe forms of HDP. …

Sports cardiology broadly encompasses the cardiovascular care of individuals who place a high premium on habitual exercise, sports performance, and/or sports competition. Some of the essential aspects within sports cardiology include the preparticipation cardiac evaluation and the management of cardiac diseases in athletes. Although most sports cardiology practitioners are trained in adult cardiology, a significant number of individuals who participate in sports are pediatric-aged, < 18 years old. Up to two-thirds of children in middle and high school participate in organized sports or are involved in nonorganized recreational sports. The cardiovascular care of pediatric-aged athletes can be challenging because many of the classic tenets and principles in adult sports cardiology do not fully generalize to pediatrics, and there is a lack of the evidence base that may be present for adult athletes. The epidemiology, presentation, and progression of cardiovascular diseases can be significantly different between pediatric and adult athletes. The evaluation of potential diseases and management considerations may also differ between pediatric and adult athletes. Similar to adults, there are "gray zones" where it is difficult to differentiate between normal exercise-induced cardiac remodeling and true cardiac pathology, but the additional lack of normative standards further complicates assessments in pediatric athletes. Management decisions for pediatric athletes are generally based on limited data but carry substantial short- and long-term implications. Thus, shared decision-making as part of the determination of clinical management strategies and for sports participation is critical and requires the participation of the parents or guardian(s). In this state-of-the-art review, key differences between pediatric and adult-aged athletes are highlighted. Specifically, how to define the "pediatric athlete," consider cardiovascular adaptations observed among pediatric athletes, determine preparticipation screening options and optimal symptom-driven evaluations in children, and consider best practices for pediatric athletes with several key cardiac conditions are detailed. The purpose of this document is to represent the first primary reference available to providers who care for pediatric athletes with cardiovascular concerns.

Tumor-Derived Arachidonic Acid Reprograms Neutrophils To Promote Immune Suppression And Therapy Resistance In Triple-Negative Breast Cancer, Liqun Yu, Keziah Liebenberg, Yichao Shen, Fengshuo Liu, Zhan Xu, Xiaoxin Hao, Ling Wu, Weijie Zhang, Hilda L Chan, Bo Wei, Philip L Lorenzi, Yang Gao, Igor Bado, Luis Becerra-Dominguez, Charlotte Helena Rivas, Sergio Aguirre, Bradley C Pingel, Yi-Hsuan Wu, Yunfeng Ding, Jun Liu, David G Edwards, Livia S Eberlin, Xiang H-F Zhang

The combination of immune checkpoint blockade and chemotherapies is the standard of care for triple-negative breast cancer (TNBC). However, initially, responsive tumors can still develop recurrences, suggesting acquired resistance mechanisms that remain poorly understood. Herein, we discover that TNBC cells surviving anti-programmed cell death protein-1 (anti-PD-1) and chemotherapy treatment accumulate neutral lipids. Disrupting lipid droplet formation in cancer cells reverses resistance and mitigates the immunosuppressive microenvironment. Single-cell RNA sequencing reveals a subset of neutrophils exhibiting a lipid-laden phenotype similar to adjacent tumor cells. Mechanistically, tumor-derived extracellular vesicles carrying lipids, including arachidonic acid (AA), mediate neutrophil reprogramming. Blocking dietary intake of …

INTRODUCTION: Acute pain is commonly experienced by millions of patients who undergo outpatient surgical procedures. Moreover, an increasing number of procedures are performed on an outpatient basis, requiring greater postoperative planning to ensure effective pain management. Analgesic approaches commonly involve prescription opioids and non-steroidal anti-inflammatory drugs (NSAIDs), but an optimal regimen that balances pain and adverse effects has not been identified. In addition, critical gaps in evidence exist regarding how opioids and NSAIDs compare as analgesic regimens after surgery.

METHODS AND ANALYSIS: The Comparing Analgesic Regimen Effectiveness and Safety after Surgery (CARES) trial is a pragmatic, international, multicentre randomised trial …

Background: Exposomes are critical drivers of carcinogenesis. However, how they modulate tumor behavior remains unclear. Extensive clinical data show cigarette smoke to be a key exposome that promotes aggressive tumors, higher rates of metastasis, reduced response to chemoradiotherapy, and suppressed anti-tumor immunity. We sought to determine whether smoke itself can modulate aggressive tumor behavior in head and neck squamous cell carcinoma (HNSCC) through reprogramming of the cellular reductive state.

Methods: Using established human and murine HNSCC cell lines and syngeneic mouse models, we utilized conventional western blotting, steady state and flux metabolomics, RNA sequencing, quantitative proteomics and flow cytometry to …

Clear cell renal cell carcinoma (ccRCC), despite having a low mutational burden, is considered immunogenic because it occasionally undergoes spontaneous regressions and often responds to immunotherapies. The signature lesion in ccRCC is inactivation of the VHL tumor suppressor gene and consequent upregulation of the HIF transcription factor. An earlier case report described a ccRCC patient who was cured by an allogeneic stem cell transplant and later found to have donor-derived T cells that recognized a ccRCC-specific peptide encoded by a HIF-responsive endogenous retrovirus (ERV), ERVE-4. We report that ERVE-4 is one of many ERVs that are induced by HIF, translated …

The Role Of Non-Statin Lipid Lowering Therapies To Reduce Ascvd Events In Primary Prevention, Chukwuemezie Mamanu, Dean Karalis

Division of Cardiology Faculty Papers

PURPOSE OF REVIEW: Atherosclerotic cardiovascular disease (ASCVD) remains a leading global health challenge, with low-density lipoprotein (LDL) cholesterol a pivotal risk factor. While statins are cornerstone therapy for lowering LDL cholesterol, many high-risk primary prevention patients are unable to tolerate statin therapy and do not achieve their guideline directed LDL cholesterol goal. For these patients, non-statin therapies offer complementary and alternative approaches to LDL cholesterol reduction.

RECENT FINDINGS: Recent advancements in non-statin therapies have expanded the options available to clinicians to lower LDL cholesterol in high-risk primary prevention patients. Yet these medications are often under-utilized in clinical practice. Observational studies, …

Conformal Predictive Intervals In Survival Analysis: A Resampling Approach, Jing Qin, Jin Piao, Jing Ning, Yu Shen

Faculty, Staff and Student Publications

The distribution-free method of conformal prediction has gained considerable attention in computer science, machine learning, and statistics. Candès et al. extended this method to right-censored survival data, addressing right-censoring complexity by creating a covariate shift setting, extracting a subcohort of subjects with censoring times exceeding a fixed threshold. Their approach only estimates the lower prediction bound for type I censoring, where all subjects have available censoring times regardless of their failure status. In medical applications, we often encounter more general right-censored data, observing only the minimum of failure time and censoring time. Subjects with observed failure times have unavailable censoring …

Computational Sensitivity Evaluation Of Ultrasound Neuromodulation Resolution To Brain Tissue Sound Speed With Robust Beamforming, Boqiang Fan, Wayne Goodman, Sameer A Sheth, Richard R Bouchard, Behnaam Aazhang

Faculty, Staff and Student Publications

Low-intensity focused ultrasound (LIFU) neuromodulation requires precise targeting and high resolution enabled by phased array transducers and beamforming. However, focusing optimization usually relies on phantom measurements or simulations with inaccurate acoustic properties to degrade neuromodulation resolution. Therefore, this work analyzes the sensitivity of neuromodulation resolution, measured by off-target activation area (OTAA), to brain tissue sound speed. A Robust Optimal Resolution (ROR) beamforming method is proposed to minimize the worst-case OTAA with restricted sound speed inaccuracy and propagation information estimated with deviated sound speed. The propagation estimation model utilizes equivalent source method (ESM) to map sound field between different acoustic parameter …

We have developed a family of biology-based mathematical models of high-grade glioma (HGG), capturing the key features of tumour growth and response to chemoradiation. We now seek to quantify the accuracy of parameter estimation and determine, when given a virtual patient cohort, which model was used to generate the tumours. In this way, we systematically test both the parameter and model identifiability. Virtual patients are generated from unique growth parameters whose growth dynamics are determined by the model family. We then assessed the ability to recover model parameters and select the model used to generate the tumour. We then evaluated …

Natural killer T cells (NKTs) are a promising platform for cancer immunotherapy, but few genes involved in the regulation of NKT therapeutic activity have been identified. To find regulators of NKT functional fitness, we developed a CRISPR/Cas9-based mutagenesis screen that uses a guide RNA (gRNA) library targeting 1,118 immune-related genes. Unmodified NKTs and NKTs expressing a GD2-specific chimeric antigen receptor (GD2.CAR) were transduced with the gRNA library and exposed to CD1d+ leukemia or CD1d-GD2+ neuroblastoma cells, respectively, over six challenge cycles in vitro. Quantification of gRNA abundance revealed enrichment of PRDM1-specific gRNAs in both NKTs and GD2.CAR NKTs, a result …
