A Review Of Recent Studies On The Pathogenesis Of Systemic Sclerosis: Focus On Fibrosis Pathways, Sergio A. Jimenez, Fabian A. Mendoza, Sonsoles Piera-Velazquez

Scleroderma Center Faculty Papers

Systemic Sclerosis (SSc) is a systemic autoimmune disease of unknown etiology characterized by the development of frequently progressive cutaneous and internal organ fibrosis accompanied by severe vascular alterations. The pathogenesis of SSc is highly complex and, despite extensive investigation, has not been fully elucidated. Numerous studies have suggested that unknown etiologic factors cause multiple alterations in genetically receptive hosts, leading to SSc development and progression. These events may be functionally and pathologically interconnected and include: 1) Structural and functional microvascular and endothelial cell abnormalities; 2) Severe oxidative stress and high reactive oxygen species (3); Frequently progressive cutaneous and visceral fibrosis; …

Department of Medical Oncology Faculty Papers

Metastatic uveal melanoma is an aggressive disease with poor outcome, which is refractory to immune checkpoint inhibitors. A T cell receptor (TCR)-based CD3 bispecific, tebentafusp, delivers clinical benefit in patients with metastatic uveal melanoma. Understanding the molecular basis for the anti-tumor activity of tebentafusp in an indication where checkpoint inhibitors are ineffective could aid in identification of other solid tumor indications where CD3 bispecifics may serve an unmet need. By analyzing tumor biopsies taken prior to treatment, early on-treatment, and at progression (NCT02570308), using RNA sequencing (RNA-seq) and immunohistochemistry (IHC), we show that expression of interferon-related genes in the tumor …

Institute of Emerging Health Professions Faculty Papers

IMPORTANCE: Driving under the influence of cannabis increases the risk of motor vehicle collisions. In some jurisdictions, deterrence rests on the ability to detect delta-9-tetrahydrocannabinol (THC) in blood. Recent evidence suggests that there may be a nuanced relationship of blood THC to driving.

OBJECTIVE: The purpose of this systematic review was to summarize all published papers investigating the presence of a linear relationship between blood THC and driving, primarily measured by simulated driving in the lab.

OUTCOMES: The main outcomes assessed included "weaving"/lateral control (eg, standard deviation of lateral position), speed, car following (following distance; coherence), reaction time, and overall …

Heterozygous Hereditary Vitamin D-Dependent Rickets Type 2a (Vddr2a) In A Patient Presenting With Pseudoarthrosis, Risa Goldberg, Gunjan Umarji, Serge Jabbour

Division of Endocrinology, Diabetes and Metabolic Diseases Faculty Papers

This case report is centered on an atypical presentation of Hereditary Vitamin D-dependent Rickets 2A (VDDR2A), a rare disorder caused by defects in the gene encoding the vitamin D receptor (VDR). While this disorder is primarily autosomal recessive in inheritance, this case demonstrates that a single heterozygous variant in the VDR gene could be linked to both phenotypic and laboratory manifestations of this condition. To understand the pathogenesis of this condition, one must know the typical roles of vitamin D, calcium, and parathyroid hormone (PTH) in maintaining homeostasis in the body. This case report focuses on the underlying pathogenesis of …

This work aimed to develop a workflow for designing and fabricating patient-derived, organ-realistic RPT phantoms and evaluate their feasibility for commissioning patient-specific RPT radioactivity quantification. Methods: We used computed tomographic (CT) and magnetic resonance (MR) imaging of representative patients, computer-aided design, and in-house 3D printing technology to design and fabricate anthropomorphic kidney and parotid phantoms with realistic organ spacing, anatomically correct orientation, and surrounding tissue heterogeneities. We evaluated the fabrication process via geometric verification (i.e., volume comparisons) and leak testing …

Global Leaders Must Be Systems Thinkers. This Is A Problem. What To Do About It., Larry M. Starr, Phd

School of Business Faculty Papers

Two cognitive approaches are described about how people including global organizational leaders understand, formulate and try to intervene and solve problems. The prevailing, conventional approach is based on analytic thinking, established 400 years ago. A second approach is systemic thinking which is less than 100 years old, and unlikely to be taught, learned or applied. Increasing evidence about the nature of problems experienced by global leaders is that the context in which problems are occurring is volatile, uncertain, complex, ambiguous and hyperconnected (VUCAH). While analytic thinking, methods and tools are appropriate and effective for problems in contexts that are stable, …

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. …

Daily Acute Intermittent Hypoxia Elicits Age & Sex-Dependent Changes In Molecules Regulating Phrenic Motor Plasticity, Jayakrishnan Nair, Alexandria Marciante, Carter Lurk, Mia Kelly, Maclain Capron, Gordon Mitchell

Department of Physical Therapy Faculty Papers

Acute intermittent hypoxia (AIH) elicits a form of respiratory motor plasticity known as phrenic long-term facilitation (pLTF). Exposure to repetitive daily AIH (dAIH) enhances pLTF, a form of metaplasticity. Little is known concerning cellular mechanisms giving rise to dAIH-induced metaplasticity and the age-dependent sexual dimorphism of AIH associated pro-plasticity mRNA expression. To test if age, sex, and dAIH effects are associated with differential expression of molecules that regulate the Q- and S-pathways and their cross-talk interactions to phrenic motor facilitation, we analyzed key regulatory molecules in ventral spinal (C3-C5) homogenates from young (3-month) and middle-aged (12-month) male and female Sprague-Dawley …
