Ret Signaling Pathway And Ret Inhibitors In Human Cancer, Angelina T Regua, Mariana Najjar, Hui-Wen Lo

Faculty, Staff and Student Publications

Rearranged during transfection (RET) receptor tyrosine kinase was first identified over thirty years ago as a novel transforming gene. Since its discovery and subsequent pathway characterization, RET alterations have been identified in numerous cancer types and are most prevalent in thyroid carcinomas and non-small cell lung cancer (NSCLC). In other tumor types such as breast cancer and salivary gland carcinomas, RET alterations can be found at lower frequencies. Aberrant RET activity is associated with poor prognosis of thyroid and lung carcinoma patients, and is strongly correlated with increased risk of distant metastases. RET aberrations encompass a variety of genomic or …

Does The Novel Coronavirus Use The Ocular Surface As An Entrance Into The Body Or As An Infection Site?, Remzi Karadag, Alp Kayiran, Christopher J Rapuano

Wills Eye Hospital Papers

This study attempts to review whether the coronavirus disease-2019 (COVID-19) is transmitted through the ocular surface and examine the symptoms and signs of ocular disease. Considering that COVID-19 is transmitted by airborne droplets and close contact with infected individuals, we will also review the conditions to which eye clinics and ophthalmologists should pay attention to prevent the transmission of the disease. Although some researchers have argued that COVID-19 transmission cannot occur through the ocular surface, most of them are of the opinion that the ocular surface is a potential pathway of transmission. Until date, ocular signs and symptoms have been …

Postoperative Breath-Holding Spells Requiring Cardiopulmonary Resuscitation After Cardiopulmonary Bypass, Rebecca Kreis, Jeffrey A. Robinson, Ali N. Ibrahimiye, Laura Ortmann

Journal Articles: Pediatrics

Breath-holding spells are common in childhood and can be associated with bradycardia and pulselessness. This report details severe breath-holding spells complicating postoperative management after atrial septal defect closure. The patient required cardiopulmonary resuscitation despite the use of a temporary pacemaker to prevent bradycardia. After multiple episodes of chest compressions, the decision was made to not intervene immediately to pulselessness and the patient was able to recover without further intervention.

Children’s Nutrition Research Center Staff Publications

The tissue-specific molecular mechanisms involved in perinatal liver and intestinal farnesoid X receptor (FXR)-fibroblast growth factor 19 (FGF19) signaling are poorly defined. Our aim was to establish how gestational age and feeding status affect bile acid synthesis pathway, bile acid pool size, ileal response to bile acid stimulation, genes involved in bile acid-FXR-FGF19 signaling and plasma FGF19 in neonatal pigs. Term (n = 23) and preterm (n = 33) pigs were born via cesarean section at 100% and 90% gestation, respectively. Plasma FGF19, hepatic bile acid and oxysterol profiles, and FXR target gene expression were assessed in pigs …

Depletion And Enrichment Of Phytosterols In Soybean Oil Lipid Emulsions Directly Associate With Serum Markers Of Cholestasis In Preterm Parenteral Nutrition-Fed Pigs, Greg Guthrie, Barbara Stoll, Shaji Chacko, Mahmoud Mohammad, Candace Style, Mariatu Verla, Oluyinka Olutoye, Deborah Schady, Charlotte Lauridsen, Nick Tataryn, Douglas Burrin

Children’s Nutrition Research Center Staff Publications

Background: Clinical reports show a positive correlation between phytosterol concentrations and severity of cholestatic liver disease markers in infants during long-term administration of parenteral lipid emulsions. Establishing a causal link between phytosterols and cholestasis has been complicated by confounding factors of lipid emulsion load, fatty acid composition, and vitamin E in many of these studies. The goal of this study is to determine whether altering the phytosterol concentration within a common soybean oil-based emulsion will alter the onset and severity of cholestasis in parenterally fed preterm piglets.

Methods: Preterm piglets were administered, for 21 days, either enteral nutrition (ENT) or …

How Do Low-Income Single-Mothers Get By When Unemployment Strikes: Patterns Of Multiple Program Participation After Transition From Employment To Unemployment, Chi-Fang Wu, Yu-Ling Chang, Soohyun Yoon, Salma Musaad

Children’s Nutrition Research Center Staff Publications

Little is known about longitudinal patterns of welfare program participation among single mothers after they transition from employment to unemployment. To better understand how utilization patterns of these welfare programs may change during the 12 months after a job loss, we used the 2008 Survey of Income and Program Participation to examine the patterns of participation in Medicaid, the Supplemental Nutrition Assistance Program, Temporary Assistance for Needy Families, and unemployment insurance among 342 single mothers who transitioned from employment to unemployment during the Great Recession. Using sequence analysis and cluster analysis, this paper identified four distinct patterns of program participation: …

Leveraging Large Multi-Center Cohorts Of Alzheimer Disease Endophenotypes To Understand The Role Of Klotho Heterozygosity On Disease Risk, Muhammad Ali, Yun Ju Sung, Fengxian Wang, Maria V. Fernández, John C. Morris, Anne M. Fagan, Richard J. Perrin, Carlos Cruchaga, Et Al

Open Access Publications

Two genetic variants in strong linkage disequilibrium (rs9536314 and rs9527025) in the Klotho (KL) gene, encoding a transmembrane protein, implicated in longevity and associated with brain resilience during normal aging, were recently shown to be associated with Alzheimer disease (AD) risk in cognitively normal participants who are APOE ε4 carriers. Specifically, the participants heterozygous for this variant (KL-SVHET+) showed lower risk of developing AD. Furthermore, a neuroprotective effect of KL-VSHET+ has been suggested against amyloid burden for cognitively normal participants, potentially mediated via the regulation of redox pathways. However, inconsistent associations and a smaller sample size of existing studies pose …

One-Carbon Metabolism In Children With Marasmus And Kwashiorkor, Thaddaeus May, Bethany De La Haye, Gabrielle Nord, Kevin Klatt, Kevin Stephenson, Sara Adams, Lucy Bollinger, Neil Hanchard, Erland Arning, Teodoro Bottiglieri, Kenneth Maleta, Mark Manary, Farook Jahoor

Open Access Publications

BACKGROUND: Kwashiorkor is a childhood syndrome of edematous malnutrition. Its precise nutritional precipitants remain uncertain despite nine decades of study. Remarkably, kwashiorkor's disturbances resemble the effects of experimental diets that are deficient in one-carbon nutrients. This similarity suggests that kwashiorkor may represent a nutritionally mediated syndrome of acute one-carbon metabolism dysfunction. Here we report findings from a cross-sectional exploration of serum one-carbon metabolites in Malawian children.

METHODS: Blood was collected from children aged 12-60 months before nutritional rehabilitation: kwashiorkor (N = 94), marasmic-kwashiorkor (N = 43) marasmus (N = 118), moderate acute malnutrition (N = 56) and controls (N = …

BACKGROUND: Recent evidence indicates a potential therapeutic role of fluvoxamine for COVID-19. In the TOGETHER trial for acutely symptomatic patients with COVID-19, we aimed to assess the efficacy of fluvoxamine versus placebo in preventing hospitalisation defined as either retention in a COVID-19 emergency setting or transfer to a tertiary hospital due to COVID-19.

METHODS: This placebo-controlled, randomised, adaptive platform trial done among high-risk symptomatic Brazilian adults confirmed positive for SARS-CoV-2 included eligible patients from 11 clinical sites in Brazil with a known risk factor for progression to severe disease. Patients were randomly assigned (1:1) to either fluvoxamine (100 mg twice …

Mean Lifetime Survival Estimates Following Solid Organ Transplantation In The Us And Uk, Christopher N Graham, Crystal Watson, Arie Barlev, Matt Stevenson, Vikas R Dharnidharka

Open Access Publications

AIMS: Accurately estimating mean survival after solid organ transplant (SOT) is crucial for efficient healthcare resource allocation decisions. However, registry-based post-transplant recipient survival estimates vary greatly and are incomplete. Often, the methods used in lifetime survival extrapolation may not fit complex transplant data and therefore alternative methods are required. We aimed to explore the flexible cubic spline methodology as a meaningful alternative for estimating lifetime survival following SOT.

METHODS: Survival analyses were conducted in kidney, liver, heart, and lung transplant recipients. Mean survival was estimated using flexible cubic splines on the hazard scale fitted with three knots, based on where …

High-Dimensional Analysis Reveals Distinct Endotypes In Patients With Idiopathic Inflammatory Myopathies, Erin M Wilfong, Todd Bartkowiak, Katherine N Vowell, Camille S Westlake, Jonathan M Irish, Peggy L Kendall, Leslie J Crofford, Rachel H Bonami

Open Access Publications

The idiopathic inflammatory myopathies (IIM) are a rare clinically heterogeneous group of conditions affecting the skin, muscle, joint, and lung in various combinations. While myositis specific autoantibodies are well described, we postulate that broader immune endotypes exist in IIM spanning B cell, T cell, and monocyte compartments. This study aims to identify immune endotypes through detailed immunophenotyping of peripheral blood mononuclear cells (PBMCs) in IIM patients compared to healthy controls. We collected PBMCs from 17 patients with a clinical diagnosis of inflammatory myositis and characterized the B, T, and myeloid cell subsets using mass cytometry by time of flight (CyTOF). …
