Faculty, Staff and Students Publications

Objectives: Congenital diaphragmatic hernia (CDH) often coexists with fetal growth restriction (FGR). The observed-to-expected (O/E) total fetal lung volume (TFLV) is used to assess CDH severity, predict outcomes, and direct fetal interventions. Expected TFLV measurements traditionally rely only on gestation age (GA). This simulation assesses how incorporating weight-adjusted GA norms affects O/E TFLV calculations in patients with isolated CDH and FGR.

Methods: A simulated dataset (n=1,005) utilized published mean fetal weight and TFLV references. Computer-generated variables included observed weights (3rd-10th %ile), O/E TFLV (10-65 %), and percent liver herniation (0-42 %). GA estimates were corrected by weight and used to …

Left Atrial Appendage Closure Devices: A Contemporary Review Of Techniques, Tips And Tricks, Kamran Namjouyan, Hafeez Ul Hassan Virk, Affan Rizwan, Muzamil Khawaja, Mahboob Alam, Markus Strauss, Chayakrit Krittanawong

Faculty, Staff and Students Publications

Atrial fibrillation (AF) affects approximately 3%-5% of adults and is projected to double in prevalence by 2060, significantly increasing the burden of thromboembolic stroke. This risk is largely attributed to thrombus formation within the left atrial appendage (LAA), particularly in nonvalvular AF, where the LAA's trabeculated anatomy, diverse morphologies (e.g., chicken wing, windsock, cactus, cauliflower), and impaired contractility allows for blood stasis and thrombogenesis. As a result, the LAA has become a focus for stroke prevention strategies. This review demonstrates current evidence on LAA closure by discussing patient selection, anatomical feasibility, procedural workflow, imaging guidance (transesophageal echocardiography vs. intracardiac echocardiography), …

Mutational Analysis Of Human Norovirus Vp2 Elucidates Critical Molecular Interactions For Virus Assembly, Janam J Dave, Sue E Crawford, Robert L Atmar, Khalil Ettayebi, B V Venkataram Prasad, Mary K Estes

Faculty, Staff and Students Publications

Human noroviruses (HuNoVs) are the leading cause of viral gastroenteritis, with ≥80% of infections caused by the GII genogroup. HuNoVs are non-enveloped, with an icosahedral capsid composed of 90 dimers of the major capsid protein VP1, which encloses a minor structural protein, VP2, and a VPg-linked, positive-sense ssRNA genome. Although the atomic structure of the icosahedral capsid formed by VP1 is well characterized using crystallography and cryo-electron microscopy analyses of HuNoV virus-like particles, the structures and the localization of VP2 and VPg inside the capsid, how they are incorporated into the capsid, and whether this process requires interactions between them …

A Spatiotemporal Model Of Cxcl10 As A Master Regulator Of Immune Evasion And Metastasis In Osteosarcoma, Benjamin B Gyau, Tsz-Kwong Man

Faculty, Staff and Students Publications

The C-X-C motif chemokine ligand 10 (CXCL10) is implicated in the progression of osteosarcoma (OS), the most aggressive pediatric bone malignancy. However, its role often presents a profound clinical paradox: although high circulating levels are strongly linked to poor prognosis, its canonical function is to recruit anti-tumor immune cells. This review unravels these contrasting roles by proposing a novel spatiotemporal model. We argue that in the early stages, immune-evading OS cells initiate the formation of a pre-metastatic niche (PMN) in the lungs, creating a localized inflammatory environment that becomes the primary source of elevated circulating CXCL10. As the disease progresses, …
