A Case Of A Massive Right Atrial Thrombus Removal Under Transesophageal Echocardiographic Guidance, Justin Phillips, Max Kabolowsky, Alex M. Hendon, Samantha Arzillo

HCA Healthcare Journal of Medicine

Background

With the advent of catheter guided interventions, practitioners have added another tool alongside chemical lysis and surgical removal to reduce the clot burden of patients with large emboli and thrombi. Due to comorbid conditions, many patients are poor candidates for surgical or chemical clot treatment but may present optimally for catheter-based thromboembolectomy. In this case, we highlight the benefits of mechanical thrombectomy with transesophageal echocardiographic guidance to reduce the clot burden of a patient who would otherwise be considered a poor candidate for surgical or chemical treatment.

The Impact Of Biomaterial Characteristics On Macrophage Phenotypes In Tissue Engineering: A Review, Julian Jackson, Hani Samarah, William Palmer, Zachary Kaplan, Marianna Nicodem, Parvesh Kumar, Spenser Short, Kelly Bridgham, Larry Harshyne, Joseph Curry

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Macrophages are highly plastic cells central to pathogen removal, tissue regeneration, and inflammation, making them key targets in biomaterial design for improved clinical outcomes. Foreign body responses (FBRs) to implanted biomaterials often involve excessive macrophage-mediated inflammation, leading to fibrotic encapsulation, infection, and implant failure. Advances in tissue engineering demonstrate that macrophage polarization - the transition from pro-inflammatory M1 to anti-inflammatory M2 phenotypes - can be influenced by biomaterial properties to mitigate these responses and enhance regeneration. This review synthesizes the relationship between biomaterial properties, such as surface chemistry, structure, and stiffness, and their ability to modulate macrophage behavior. Key innovations, …

Endocarditis Prophylaxis In Vulnerable Valve; Antibiotic Stewardship Or Suboptimal Care?, Zachary Taylor, Andrea Roast, Michael Layoun

Providence Portland Medical Center Internal Medicine 2025

Introduction Infective endocarditis (IE) is a relatively uncommon disease with an annual incidence of 5 per 100,000 people in the U.S.. Dental procedures are an exceptionally rare cause of IE. Amidst a global emphasis on antibiotic stewardship, U.S. and European guidelines only recommend antibiotic prophylaxis for dental procedures in high-risk groups. Having a bicuspid aortic valve (BAV) confers an 11-fold risk of endocarditis compared to the general public, and yet, is not classified as high-risk per AHA/IDSA guidelines. We present a patient with BAV who developed IE following a noninvasive dental procedure and review whether patients with BAV are under-classified …

Network-Based Clustering Unveils Interconnected Landscapes Of Genomic And Clinical Features Across Myeloid Malignancies, Fritz Bayer, Marco Roncador, Giusi Moffa, Kiyomi Morita, Koichi Takahashi, Niko Beerenwinkel, Jack Kuipers

Faculty, Staff and Student Publications

Myeloid malignancies exhibit considerable heterogeneity with overlapping clinical and genetic features among subtypes. We present a data-driven approach that integrates mutational features and clinical covariates at diagnosis within networks of their probabilistic relationships, enabling the discovery of patient subgroups. A key strength is its ability to include presumed causal directions in the edges linking clinical and mutational features, and account for them aptly in the clustering. In a cohort of 1323 patients, we identify subgroups that outperform established risk classifications in prognostic accuracy. Our approach generalises well to unseen cohorts with classification based on our subgroups similarly offering advantages in …

Neurotransmitter Power Plays: The Synaptic Communication Nexus Shaping Brain Cancer, Jayanta Mondal, Jason T Huse

Faculty, Staff and Student Publications

Gliomas and brain metastases are notorious for their dismal prognosis and low survival rates, a challenge exacerbated by our incomplete grasp of the complex dynamics that govern brain cancers. Recently, a groundbreaking paradigm shift has emerged, highlighting the crucial role of synaptic communication between neurons and brain tumor cells in reshaping neuronal signaling to favor tumor growth. This review delves into the pivotal interplay of synaptic mechanisms, focusing on excitatory glutamatergic and inhibitory GABAergic pathways. Glutamatergic synapses utilize glutamate to propagate excitatory signals, while GABAergic synapses employ gamma-aminobutyric acid (GABA) to inhibit neuronal firing. Glutamatergic signaling can be broadly classified …
