Respiratory syncytial virus (RSV) bronchiolitis is not only the leading cause of hospitalization in U.S. infants, but also a major risk factor for asthma development. While emerging evidence suggests clinical heterogeneity within RSV bronchiolitis, little is known about its biologically-distinct endotypes. Here, we integrated clinical, virus, airway microbiome (species-level), transcriptome, and metabolome data of 221 infants hospitalized with RSV bronchiolitis in a multicentre prospective cohort study. We identified four biologically- and clinically-meaningful endotypes: A) clinical

Usage Of 3d Models Of Tetralogy Of Fallot For Medical Education: Impact On Learning Congenital Heart Disease., Yue-Hin Loke, Ashraf S Harahsheh, Axel Krieger, Laura J Olivieri

Pediatrics Faculty Publications

BACKGROUND: Congenital heart disease (CHD) is the most common human birth defect, and clinicians need to understand the anatomy to effectively care for patients with CHD. However, standard two-dimensional (2D) display methods do not adequately carry the critical spatial information to reflect CHD anatomy. Three-dimensional (3D) models may be useful in improving the understanding of CHD, without requiring a mastery of cardiac imaging. The study aimed to evaluate the impact of 3D models on how pediatric residents understand and learn about tetralogy of Fallot following a teaching session.

METHODS: Pediatric residents rotating through an inpatient Cardiology rotation were recruited. The …

Prevention Of Recurrent Affective Episodes Using Extinction Training In The Reconsolidation Window: A Testable Psychotherapeutic Strategy., Robert M Post, Robert Kegan Mar 2017

Prevention Of Recurrent Affective Episodes Using Extinction Training In The Reconsolidation Window: A Testable Psychotherapeutic Strategy., Robert M Post, Robert Kegan

Psychiatry and Behavioral Sciences Faculty Publications

Stressors may initially precipitate affective episodes, but with sufficient numbers of recurrences, episodes can occur more autonomously. It is postulated the memory engram for these recurrent depressions moves from the conscious representational memory system to the unconscious habit memory system encoded in the striatum. If this were the case, cognitive behavior therapy targeted toward extinction of habit memories could be an effective maneuver for helping reverse the automaticity of affective episode recurrence. Extinction training in the reconsolidation window (which opens about 5 min to 1 h after active memory recall) can revise, reverse, or eliminate the long term memories associated …


Sustained Nitric Oxide-Releasing Nanoparticles Interfere With Methicillin-Resistant Staphylococcus Aureus Adhesion And Biofilm Formation In A Rat Central Venous Catheter Model., Mircea Radu Mihu, Vitor Cabral, Rodney Pattabhi, Moses T Tar, Kelvin P Davies, Adam J Friedman, Luis R Martinez, Joshua D Nosanchuk Jan 2017

Sustained Nitric Oxide-Releasing Nanoparticles Interfere With Methicillin-Resistant Staphylococcus Aureus Adhesion And Biofilm Formation In A Rat Central Venous Catheter Model., Mircea Radu Mihu, Vitor Cabral, Rodney Pattabhi, Moses T Tar, Kelvin P Davies, Adam J Friedman, Luis R Martinez, Joshua D Nosanchuk

Dermatology Faculty Publications

Staphylococcus aureus is frequently isolated in the setting of infections of indwelling medical devices, which are mediated by the microbe's ability to form biofilms on a variety of surfaces. Biofilm-embedded bacteria are more resistant to antimicrobial agents than their planktonic counterparts and often cause chronic infections and sepsis, particularly in patients with prolonged hospitalizations. In this study, we demonstrate that sustained nitric oxide-releasing nanoparticles (NO-np) interfere with S. aureus adhesion and prevent biofilm formation on a rat central venous catheter (CVC) model of infection. Confocal and scanning electron microscopy showed that NO-np-treated staphylococcal biofilms displayed considerably reduced thicknesses and bacterial …

Training Us Health Care Professionals On Human Trafficking: Where Do We Go From Here?, Clydette Powell, Kirsten Dickins, Hanni Stoklosa

Pediatrics Faculty Publications

Some 21 million adults and children are labor-trafficked or sex-trafficked through force, fraud, or coercion. In recognition of the interface between trafficking victims and the healthcare setting, over the last 10 years there has been a notable increase in training of health care professionals (HCPs) on human trafficking (HT) and its health implications. Many organizations have developed curricula and offered training in various clinical settings. However, methods and content of this education on trafficking vary widely, and there is little evaluation of the impact of the training. The goal of this study was to assess the gaps and strengths in …

Method And Phantom To Study Combined Effects Of In-Plane (X,Y) And Z-Axis Resolution For 3d Ct Imaging., David Goodenough, Josh Levy, Smari Kristinsson, Jesper Fredriksson, Hildur Olafsdottir, Austin Healy

Radiology Faculty Publications

Increasingly, the advent of multislice CT scanners, volume CT scanners, and total body spiral acquisition modes has led to the use of Multi Planar Reconstruction and 3D datasets. In considering 3D resolution properties of a CT system it is important to note that both the in-plane (x,y) and z-axis (slice thickness) influence the visual-ization and detection of objects within the scanned volume. This study investigates ways to consider both the in-plane resolution and the z-axis resolution in a single phantom wherein analytic or visualized analysis can yield information on these combined effects. A new phantom called the "Wave Phantom" is …

How Complicated Can It Be? The Link Between Apol1 Risk Variants And Lipoprotein Heterogeneity In Kidney And Cardiovascular Diseases., Chien-An A Hu, Patricio E Ray

Pediatrics Faculty Publications

The beginning of human apolipoprotein L1 study (gene: APOL1; protein: ApoL1) originated from the identification of circulating ApoL1 as an interacting protein of ApoA1 and a minor component of high-density lipoprotein subfraction 3 (HDL3) in 1997 [1]. In the past 18 years, ApoL1 has been investigated in the context of complex human diseases such as African sleeping sickness, schizophrenia, host innate immunity, cancer, hyperlipidemia, cardiovascular diseases, stroke and type 2 diabetes [2–10]. A major breakthrough, however, was the documentation of two haplotypes of APOL1, harboring three coding-sequence mutations as risk variants associated with non-diabetic …
