Cmv-Responsive Cd4 T Cells Have A Stable Cytotoxic Phenotype Over The First Year Post-Transplant In Patients Without Evidence Of Cmv Viremia, Lauren E. Higdon, Ayah A. Amad, Steven Schaffert, Kenneth B. Margulies, Jonathan S. Maltzman

Publications and Research

Cytomegalovirus (CMV) infection is a known cause of morbidity and mortality in solid organ transplant recipients. While primary infection is controlled by a healthy immune system, CMV is never eradicated due to viral latency and periodic reactivation. Transplantation and associated therapies hinder immune surveillance of CMV. CD4 T cells are an important part of control of CMV reactivation. We therefore investigated how CMV impacts differentiation, functionality, and expansion of protective CD4 T cells from recipients of heart or kidney transplant in the fi rst year post-transplant without evidence of CMV viremia. We analyzed longitudinal peripheral blood samples by flow cytometry …

An Epidemic Model With Time-Distributed Recovery And Death Rates, Samiran Ghosh, Vitaly Volpert, Malay Banerjee

Faculty, Staff and Student Publications

A compartmental epidemiological model with distributed recovery and death rates is proposed. In some particular cases, the model can be reduced to the conventional SIR model. However, in general, the dynamics of epidemic progression in this model is different. Distributed recovery and death rates are evaluated from COVID-19 data. The model is validated by the epidemiological data for different countries, and it shows better agreement with the data than the SIR model. The time-dependent disease transmission rate is estimated.

Epigenetic abnormalities in DNA hydroxymethylation (5hmC) have been detected in patients with myeloid neoplasms, suggesting that 5hmC might act as a valuable epigenetic mark to reflect the disease status of myeloid neoplasms. Here, we report systematic genome-wide mapping of the DNA hydroxymethylomes in over 70 patients with myeloid neoplasms. Our integrative analysis leads to the identification of distinct 5hmC signatures that can sensitively discriminate patients from healthy individuals. At the molecular level, we unveiled dynamic 5hmC changes within key transcription factor (e.g., the CEBP family) binding motifs that are essential for hematopoiesis and myeloid lineage specification. 5hmC redistribution was found …

Mexican Americans have a high prevalence of diabetes and burden of diabetes-related complications, highlighting the need for novel preventive strategies and noninvasive predictors of diabetes risk tailored to this population. Changes in the gut microbiome have the potential to predict diabetes. Here, we aimed to identify alterations in the gut microbiome associated with diabetes in the high-risk population of Mexican Americans in South Texas. Stool samples were collected from 216 subjects from the population-based Cameron County Hispanic Cohort. Among them, 75 had type 2 diabetes. Taxonomic and functional profiling of the stool samples were assessed by 16S and shotgun metagenomic …

Divergent Outer Retinal Circuits Drive Image And Non-Image Visual Behaviors, Corinne Beier, Ulisse Bocchero, Lior Levy, Zhijing Zhang, Nange Jin, Stephen C Massey, Christophe P Ribelayga, Kirill Martemyanov, Samer Hattar, Johan Pahlberg

Image- and non-image-forming vision are essential for animal behavior. Here we use genetically modified mouse lines to examine retinal circuits driving image- and non-image-functions. We describe the outer retinal circuits underlying the pupillary light response (PLR) and circadian photoentrainment, two non-image-forming behaviors. Rods and cones signal light increments and decrements through the ON and OFF pathways, respectively. We find that the OFF pathway drives image-forming vision but cannot drive circadian photoentrainment or the PLR. Cone light responses drive image formation but fail to drive the PLR. At photopic levels, rods use the primary and secondary rod pathways to drive the …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) utilizes a number of strategies to modulate viral and host mRNA translation. Here, we used ribosome profiling in SARS-CoV-2-infected model cell lines and primary airway cells grown at an air-liquid interface to gain a deeper understanding of the translationally regulated events in response to virus replication. We found that SARS-CoV-2 mRNAs dominate the cellular mRNA pool but are not more efficiently translated than cellular mRNAs. SARS-CoV-2 utilized a highly efficient ribosomal frameshifting strategy despite notable accumulation of ribosomes within the slippery sequence on the frameshifting element. In a highly permissive cell line model, …

Primary Middle Meningeal Artery Embolization For A Chronic Subdural Hematoma After Non-Accidental Trauma In A Child: A Case Report, Saisree Ravi, Sohum Desai, Ameer E. Hassan, Wondwossen G. Tekle

School of Medicine Publications

Chronic subdural hematoma in children can be pathognomonic of abusive head trauma. Treatment options for these range from observation to surgical evacuation depending on clinical circumstance and presenting features, which can include mental status changes, headaches, focal neurologic deficits, or asymptomatic presentation. Standalone endovascular treatments represent an area of growing interest in the adult population as an effective treatment modality. However, embolization as a singular treatment approach has not been reported in the pediatric population. We report the first case of stand-alone middle meningeal artery (MMA) embolization of a chronic subdural hematoma as a sequela of abusive head trauma in …

Promoting Subjective Well-Being In Middle School: Role Of Internalizing And Externalizing Behaviors In A Targeted Positive Psychology Intervention, Letty Langton Dileo

USF Tampa Graduate Theses and Dissertations

In a dual-factor model, complete mental health entails average-to-high subjective well-being (SWB, happiness) and few internalizing and externalizing behaviors (IEB, mental illness). Although positive psychology interventions (PPIs) have been shown to increase middle school students’ SWB, more research is needed to understand how baseline IEB influences post-intervention outcomes. The current study examined the effect of baseline IEB on SWB outcomes for 122 middle school students who participated in the Well-Being Promotion Program (WBPP). The WBPP is a 10-week, small group, school-based PPI for students with low SWB, as identified from universal screening of life satisfaction. The dataset analyzed is part …

Loss Of Stathmin-2, A Hallmark Of Tdp-43-Associated Als, Causes Motor Neuropathy, Kelsey L Krus, Amy Strickland, Yurie Yamada, Laura Devault, Robert E Schmidt, A Joseph Bloom, Jeffrey Milbrandt, Aaron Diantonio

2020-Current year OA Pubs

TDP-43 mediates proper Stathmin-2 (STMN2) mRNA splicing, and STMN2 protein is reduced in the spinal cord of most patients with amyotrophic lateral sclerosis (ALS). To test the hypothesis that STMN2 loss contributes to ALS pathogenesis, we generated constitutive and conditional STMN2 knockout mice. Constitutive STMN2 loss results in early-onset sensory and motor neuropathy featuring impaired motor behavior and dramatic distal neuromuscular junction (NMJ) denervation of fast-fatigable motor units, which are selectively vulnerable in ALS, without axon or motoneuron degeneration. Selective excision of STMN2 in motoneurons leads to similar NMJ pathology. STMN2 knockout heterozygous mice, which better model the partial loss …

Gain-Of-Signal Assays For Probing Inhibition Of Sars-Cov-2 Mpro/3clpro In Living Cells, Seyed Arad Moghadasi, Morgan A Esler, Yuka Otsuka, Jordan T Becker, Sofia N Moraes, Constance B Anderson, Srinivas Chamakuri, Christopher Belica, Chloe Wick, Daniel A Harki, Damian W Young, Louis Scampavia, Timothy P Spicer, Ke Shi, Hideki Aihara, William L Brown, Reuben S Harris

The main protease, Mpro, of SARS-CoV-2 is required to cleave the viral polyprotein into precise functional units for virus replication and pathogenesis. Here, we report quantitative reporters for Mpro function in living cells in which protease inhibition by genetic or chemical methods results in robust signal readouts by fluorescence (enhanced green fluorescent protein [eGFP]) or bioluminescence (firefly luciferase). These gain-of-signal systems are scalable to high-throughput platforms for quantitative discrimination between Mpro mutants and/or inhibitor potencies as evidenced by validation of several reported inhibitors. Additional utility is shown by single Mpro amino acid variants and structural information combining to demonstrate that …

Expanding Anti-Cd38 Immunotherapy For Lymphoid Malignancies, Xu Wang, Xinfang Yu, Wei Li, Praveen Neeli, Ming Liu, Ling Li, Mingzhi Zhang, Xiaosheng Fang, Ken H Young, Yong Li

Faculty, Staff and Students Publications

BACKGROUND: Lymphoid neoplasms, including multiple myeloma (MM), non-Hodgkin lymphoma (NHL), and NK/T cell neoplasms, are a major cause of blood cancer morbidity and mortality. CD38 (cyclic ADP ribose hydrolase) is a transmembrane glycoprotein expressed on the surface of plasma cells and MM cells. The high expression of CD38 across MM and other lymphoid malignancies and its restricted expression in normal tissues make CD38 an attractive target for immunotherapy. CD38-targeting antibodies, like daratumumab, have been approved for the treatment of MM and tested against lymphoma and leukemia in multiple clinical trials.

METHODS: We generated chimeric antigen receptor (CAR) T cells targeting …

Mycn-Driven Fatty Acid Uptake Is A Metabolic Vulnerability In Neuroblastoma, Ling Tao, Mahmoud A Mohammad, Giorgio Milazzo, Myrthala Moreno-Smith, Tajhal D Patel, Barry Zorman, Andrew Badachhape, Blanca E Hernandez, Amber B Wolf, Zihua Zeng, Jennifer H Foster, Sara Aloisi, Pavel Sumazin, Youli Zu, John Hicks, Ketan B Ghaghada, Nagireddy Putluri, Giovanni Perini, Cristian Coarfa, Eveline Barbieri

Neuroblastoma (NB) is a childhood cancer arising from sympatho-adrenal neural crest cells. MYCN amplification is found in half of high-risk NB patients; however, no available therapies directly target MYCN. Using multi-dimensional metabolic profiling in MYCN expression systems and primary patient tumors, we comprehensively characterized the metabolic landscape driven by MYCN in NB. MYCN amplification leads to glycerolipid accumulation by promoting fatty acid (FA) uptake and biosynthesis. We found that cells expressing amplified MYCN depend highly on FA uptake for survival. Mechanistically, MYCN directly upregulates FA transport protein 2 (FATP2), encoded by SLC27A2. Genetic depletion of SLC27A2 impairs NB survival, and …

2022 Providence Nurse Research Conference

Background:

The American Nurse Credentialing Center’s (ANCC) Magnet® recognition promotes best patient outcomes and nurse practice environments within a healthcare organization and requires nurses to conduct research and disseminate findings. However, while undergraduate nursing programs recognize the need to provide research knowledge, current pre-licensure curriculum is not designed to engage students in research activities to foster competency in this skill. Despite research competencies endorsed by select national nursing organizations and the Magnet® designation requirements, RN competency levels for participating in research activities are reported to be suboptimal. Thus, best practice recommends a formal program to train and guide nurses in …

Podium Presentation: Impact Of An Interprofessional Culture Of Mobility Training On Documentation Of Patient Mobility Activities, Dawn Doud, Micah Kaluzny, Ryan Houser, Teresa Bigand

2022 Providence Nurse Research Conference

Background:

Adults, and particularly elder adults, suffer many adverse consequences when restricted to the bed with no mobility activities for extended periods of time. During a hospital visit, adults are often subjected to bedrest inappropriately, contributing to outcomes such as hospital-acquired infections or injury, muscle wasting, or falls with injury. All outcomes may cause an increased length of stay and risk likelihood of discharge to an extended care facility versus home. At one community-based hospital, a needs assessment revealed several staff self-reported barriers to mobilizing patients. Simultaneously, no evidence-based practice mobility program existed within the hospital.

Purpose:

The purpose of …

Podium Presentation: Continuous Labor Epidural Placement Trends Among Parturients: An Evidence-Based Practice Project, Aleksandr A. Lyakhov, Teresa Bigand, Amanda Affleck, Kenn Daratha, Kris Daratha

2022 Providence Nurse Research Conference

Background:

Childbirth is very painful, and unmanaged pain may reduce patient satisfaction or lead to other complications. Evidence indicates that pain severity is lower among parturient women administered analgesia via a continuous labor epidural (CLE) and that maternal request is sufficient indication for CLE placement to manage labor pain. In some cases, a medical induction of labor may be scheduled, offering an opportunity for proactive pain management from hospital staff. Yet, trends on timing of CLE placement among parturient women with scheduled labor induction versus spontaneous labor in hospitals in Eastern Washington at one health system are unclear.

Purpose:

Sinus Pauses And Asystole As A Rare Presentation Of Thyrotoxic Crisis: A Case Report, Christian Akem Dimala, Charnjeet Sandhu, Oreoluwa Oladiran, Agnieszka Mochon, William Finneran Iii

Transformative Medicine

Introduction

Thyroid crisis is a rare and life-threatening endocrine emergency characterized by exaggerated clinical manifestations of hyperthyroidism with cardiovascular manifestations being the most severe. Rhythm disturbances, sinus tachycardia and atrial fibrillation, are the commonest cardiac manifestations of severe thyrotoxicosis; however, asystole remains a very atypical and uncommon presentation. We present a case of thyrotoxicosis due to Grave’s disease complicated by multiple episodes of asystole.

Case Presentation

A 65-year-old female recently diagnosed with Grave’s disease presented to the hospital with recurrent episodes of syncope. Her hospital course was significant for atrial fibrillation with subsequent progression to sinus pauses and asystole spontaneously …

The Modified Rankin Scale Can Accurately Be Derived From The Electronic Medical Record, Derek Isenberg, Nelson Prus, Frederick Ramsey, Nina T. Gentile

Transformative Medicine

Abstract

Introduction

The modified Rankin Scale (mRS) is used to assess functional outcomes after a stroke and is the primary outcome in many stroke trials. For retrospective stroke research or stroke research in which patients are lost to study follow up, review of the electronic medical record (EMR) may be the sole way to estimate a patient’s functional outcome. The purpose of this study is to determine if a mRS can be accurately derived from the electronic medical record EMR.

Methods

This study used data from completed stroke studies in which in-person 90-day mRS were collected as part of the …
