Faculty, Staff and Student Publications

Superior vena cava (SVC) syndrome is a clinical condition characterized by impaired venous return from the upper body due to intrinsic or extrinsic obstruction of the SVC. Endovascular stenting has become an effective intervention for symptomatic relief. However, the procedure carries a rare risk of life-threatening complications, including SVC perforation and cardiac tamponade. This study describes a 60-year-old male with SVC syndrome secondary to squamous cell carcinoma of the lung who developed SVC perforation and cardiac tamponade during endovascular stenting. Despite initial hemodynamic compromise and cardiac arrest, prompt intervention with pericardiocentesis, aggressive resuscitation, and deployment of a covered stent resulted …

Patient Outcomes Following Parasagittal Interlaminar Epidural Steroid Injections For Bilateral Lumbar Radicular Symptoms: Correlation Of Contrast Spread With Symptom Relief, Jamal Hasoon, Omar Viswanath, Alan D Kaye, Alberto Pasqualucci, Giustino Varrassi

Faculty, Staff and Student Publications

Introduction Bilateral lumbar radicular symptoms are commonly treated with interlaminar epidural steroid injections (ILESIs). The parasagittal approach often results in unilateral contrast spread, which may influence the degree of bilateral symptom relief. This study evaluates whether unilateral contrast spread correlates with symptom improvement in both ipsilateral and contralateral symptoms. Methods A retrospective review of six patients with bilateral lumbar radiculopathy secondary to lumbar degenerative disc disease, spondylosis, or disc herniation was conducted. All patients underwent ILESIs using a parasagittal approach. The injectate consisted of bupivacaine, preservative-free normal saline, and triamcinolone. Contrast spread was assessed fluoroscopically, and symptom relief was evaluated …

Faculty, Staff and Student Publications

The recently published DISCHARGE-1 trial supports the observations of earlier autopsy and neuroimaging studies that almost 70% of all focal brain damage after aneurysmal subarachnoid hemorrhage are anemic infarcts of the cortex, often also affecting the white matter immediately below. The infarcts are not limited by the usual vascular territories. About two-fifths of the ischemic damage occurs within ~ 48 h; the remaining three-fifths are delayed (within ~ 3 weeks). Using neuromonitoring technology in combination with longitudinal neuroimaging, the entire sequence of both early and delayed cortical infarct development after subarachnoid hemorrhage has recently been recorded in patients. Characteristically, cortical …

From Stable Teamwork To Dynamic Teaming In The Ambulatory Care Diagnostic Process, Scott I Tannenbaum, Eric J Thomas, Sigall K Bell, Eduardo Salas

Faculty, Staff and Student Publications

Dynamic teaming is required whenever people must coordinate with one another in a fluid context, particularly when the fundamental structures of a team, such as membership, priorities, tasks, modes of communication, and location are in near-constant flux. This is certainly the case in the contemporary ambulatory care diagnostic process, where circumstances and conditions require a shifting cast of individuals to coordinate dynamically to ensure patient safety. This article offers an updated perspective on dynamic teaming commonly required during the ambulatory diagnostic process. Drawing upon team science, it clarifies the characteristics of dynamic diagnostic teams, identifies common risk points in the …

Protein Arginine Methyltransferases As Regulators Of Cellular Stress, Julia Zaccarelli-Magalhães, Cristiane Teresinha Citadin, Julia Langman, Drew James Smith, Luiz Henrique Matuguma, Hung Wen Lin, Mariana Sayuri Berto Udo

Faculty, Staff and Student Publications

Arginine modification can be a "switch" to regulate DNA transcription and a post-translational modification via methylation of a variety of cellular targets involved in signal transduction, gene transcription, DNA repair, and mRNA alterations. This consequently can turn downstream biological effectors "on" and "off". Arginine methylation is catalyzed by protein arginine methyltransferases (PRMTs 1-9) in both the nucleus and cytoplasm, and is thought to be involved in many disease processes. However, PRMTs have not been well-documented in the brain and their function as it relates to metabolism, circulation, functional learning and memory are understudied. In this review, we provide a comprehensive …

Non-Invasive Prenatal Screening: Testing Motivations And Decision Making In The Low-Risk Population, Jenna K Lea, Blair K Stevens, Shannon Mulligan, Syed S Hashmi, Rebecca Lunstroth, Meagan G Choates

Faculty, Staff and Student Publications

Non-invasive prenatal screening provides a risk assessment for aneuploidies by utilizing cell-free DNA (cfDNA). It is recommended that cell-free DNA screening (cfDNA screening) be offered to all pregnant people regardless of a priori risk for aneuploidy. In the absence of an increased risk, alternative motives for electing cfDNA screening and different levels of informed decision making may arise. Therefore, our study aimed to characterize low-risk patients' motivations for cfDNA screening election, determine how often informed decisions are being made, and compare motivations between informed and uninformed decision makers. A survey that included a modified, validated measure of informed choice (MMIC) …

Faculty, Staff and Student Publications

The metabolome and lipidome comprise the thousands of molecular compounds in an organism. Molecular compounds consist of the upstream metabolic components of intracellular reactions or the byproducts of cellular pathways. Molecular and biochemical perturbations are associated with disorders in newborns and infants. The diagnosis of inborn errors of metabolism has relied on targeted metabolomics for several decades. Newer approaches offer the potential to identify novel biomarkers for common diseases of the newborn and infant. They may also elucidate novel predictive or diagnostic measures for a variety of health trajectories. Here, we review the relevance of the metabolome and lipidome for …

Large-scale whole-genome sequencing (WGS) studies have improved our understanding of the contributions of coding and noncoding rare variants to complex human traits. Leveraging association effect sizes across multiple traits in WGS rare variant association analysis can improve statistical power over single-trait analysis, and also detect pleiotropic genes and regions. Existing multi-trait methods have limited ability to perform rare variant analysis of large-scale WGS data. We propose MultiSTAAR, a statistical framework and computationally scalable analytical pipeline for functionally informed multi-trait rare variant analysis in large-scale WGS studies. MultiSTAAR accounts for relatedness, population structure and correlation among phenotypes by jointly analyzing multiple …
